The invention relates to a portable cleaning device, in particular to a portable vacuum cleaner. More specifically the invention relates to a portable cleaning device with a cyclone separator.

Portable vacuum cleaners are well known and are manufactured and sold by various manufacturers for several years. Usually portable vacuum cleaner includes a housing that encloses the motor and fan unit for drawing air into the vacuum cleaner through the entrance, and a separating device, such as a filter or bag, for separating dirt and dust from the incoming air stream. An example of such a vacuum cleaner is described in the document GB 1207278.

Recently developed portable vacuum cleaners with built-in cyclone separator systems, which are able to remove larger particles of debris from the air stream before removing smaller particles using a filter or other barrier methods. For example, such a device is sold by Black & Decker under the trade name DUSTBUSTER. An additional example of a portable vacuum cleaner with a cyclone separator described in the document GB 2035787 A.

The disadvantage of portable vacuum cleaners that use cyclonic separators, is that when there is only one cyclone, followed by a filter or a bag filter requires rinse the deposits or by washing, or replacement. Lack of maintenance leads to poor performance.

The objective of the invention is to provide a portable cleaning device that would be able to maintain high performance for longer than known portable vacuum cleaners. Additional objectives of the present invention is to provide a portable cleaning device, which would require less maintenance than existing devices, and would be able to develop and maintain greater suction power than existing portable vacuum cleaners.

Portable cleaning device according to the invention contains the inlet for dirty air, an outlet for clean air and separating device located in the path of air flow between the inlet and outlet of air for separating dirt and dust from the air stream, and separating device comprises a cyclone separator with at least one first cyclone, with a cyclone separator further comprises multiple second cyclones arranged in parallel to each other further along from one or each of the first cyclone.

Because of the presence of a cyclone separator with multiple second cyclones arranged in parallel, portable cleaning device is able to separate fine particles of dirt and dust without the use of barrier with the of edst, for example, filters or bags that need maintenance to maintain high performance over a certain period of time. Up to this time was considered to be difficult to create a cyclone separator of this type of portable vacuum cleaner, because it takes too much and ill suited for a handheld device. An additional advantage of installing the cyclone separator of this type of portable vacuum cleaner is that the vacuum in this case is able to maintain a high suction power, because there is no filter means barrier type, causing a decrease with time of suction power and, therefore, collecting ability.

Preferably, the portable cleaning device includes a handle, and a cyclone separator located between the handle and inlet for dirty air. This location provides good balance for the user of this type of cleaning device.

Preferably a cyclone separator is essentially parallel to the handle and it is desirable that it was located essentially vertically. This embodiment of the vacuum cleaner simplifies the manipulation of the device and increases as a convenience store, and remove dirt and dust from the cyclone separator.

In a preferred embodiment of the invention portable Chi is shining, the device contains one first cyclone, and the second cyclones arranged around the axis of the first cyclone. This provides a compact design and balance for ease of manipulation. More preferably, the second ends of the cyclones went into the first cyclone to ensure consistency between pylesobirajushchaja capacity and total cyclone separator.

Option of carrying out the invention is described hereinafter with reference to the accompanying drawings.

Figure 1 shows the portable cleaning device according to the invention;

figure 2 is a side view of the device shown in figure 1;

figure 3 is a longitudinal cross-section of the cyclone separating device of the device shown in figure 1.

As shown in figures 1 and 2, a portable vacuum cleaner 10 includes a main body 12 that houses a motor and fan unit (not shown). The main body 12 also includes a source 14 of the power supply such as a battery. On the main body 12 has a handle 16 for manipulating the vacuum cleaner 10 during use.

At the far end of the entrance 18 adjustably mounted brush nozzle 22. In the main body 12 made a number of outlet openings 24 for withdrawal of air from a portable vacuum cleaner 10.

clanny separator 100 is located between the main body 12 and the inlet 18 for dirty air. Thus, a cyclone separator 100 is located between the handle 16 and inlet 18 for dirty air. The longitudinal axis 26 of the cyclone separator 100 is held essentially in the vertical direction, so that the axis 26 and, therefore, a cyclone separator 100 are essentially parallel to the handle 16.

The orientation of the handle 16 is such that when the gripping hand of the user clenches into a fist just as it happens when you capture saws. In the wrist of the user is not strained more than is needed during the manipulation portable vacuum cleaner 10 during cleaning. A cyclone separator 100 is located close to the handle 16, which also reduces the torque applied to the wrist of the user during use of the portable vacuum cleaner 10. The handle 16 has a switch 20 in the form of a lever to turn on and turn off the engine of a vacuum cleaner.

Figure 3 depicts the cyclone separation device 100, which forms part of a portable vacuum cleaner 10. Cyclone separation device 100 includes the first cyclone 102 with a longitudinal axis X-X, which has a wall 104. On the upper wall section 104 log 110. Input 110 is connected to the input 18 for dirty air and forms a connecting channel between the inlet 18 for dirty air and the inner part of the first cyclone 102. Input 110 for air is tangent to the first cyclone 102, the AK that the incoming air is forced to follow a spiral around the inner space of the first cyclone 102.

One end of the first cyclone 102 is closed by the base 116. The base 116 is installed on the lower end wall 104 of the first cyclone can be rotated by means of hinges 118. The base 116 is held in the closed position (as shown in the drawings) with the latch 120.

Inside wall 104 of the first cyclone 102 is a housing 121 containing a cylindrical wall 122 with many through holes 123. The casing 121 surrounds the output 124 from the first cyclone 102. The output 124 forms a connecting channel between the first cyclone 102 and the block 126 of second cyclones. At the base of the casing 121 is made protrusion 128 with many through holes 129, through which may pass through the air, capturing dirt and dust.

Block 126 of second cyclones contains several arranged parallel to each of the second cyclones 130. In this embodiment, the invention provides for a six second cyclones 130. Second cyclones 130 are arranged around the axis x-X of the first cyclone 102. The location of the second cyclones 130 such that the second cyclones are spaced at equal angles around the axis X-X. Each of the second cyclone 130 is tangent input 132 for air and exit 134 for air. Each inlet 132 and outlet 134 for air are located on the first end of the respective second cyclone 130. On the second end of each second cyclone 130 is tapered hole 136. PL is scost conical holes 136 of each of the second cyclone 130 is inclined relative to the longitudinal axis (not shown) corresponding to the next cyclone 130. Tapered bore 136 of each of the second cyclones 130 is connected with the channel 138 formed by the wall 140 located inside the casing 121.

The second end of each second cyclone 130 is inside the first cyclone 102. The first end of each second cyclone 130 is located outside the housing of the first cyclone 102. In the form shown in the drawing, the orientation of the lower end of each of the second cyclone 130 is in the upper end of the first cyclone 102. On the upper end of the first cyclone 102 is input 110 so that the input 110 is located in the cyclone separator 100 in which the first and second cyclones 102, 130 overlap. Because the first ends of the second cyclones 130 is located outside the housing of the first cyclone, this area of cyclone separator 100 is located between the upper and lower ends of the cyclone separator 100. Inlet connection 18 for dirty air from the cyclone separator 100 at its intermediate section is useful for manipulating portable vacuum cleaner 10 and prevents accidental bumps on the lower legs of the device on the surface, remote from the working area.

At the lower end of the channel 138 is manifold 142, which contains the first section 144 in the form of a truncated cone and a cylindrical second section 146. The inner space of the collector 142 is limited by the base 116 and the sides of the first and the second phase is at 144, 146 collector 142.

Each of the outputs 134 for air second cyclones 130 is connected with the tube 150, providing air flow from the cyclone separation device 100 in other parts of the portable vacuum cleaner 10. At the far end of the tube 150 is motor filter 152. Motor filter 152 contains a porous material, for example foam, and may also include filtering material fine cleaning. Motor filter 152 is designed to prevent any fine dust particles into the engine and damage.

During use, when pressed the switch 20, the motor and fan unit sucking air stream saturated with dirt air into the inlet 18 and then into a cyclone separator 100. Saturated with dirt air enters the cyclone separator 100 through the inlet 110. Due to the location of the tangent of the input 110 of the air flow is forced to follow a spiral along the inner surface of the wall 104. Larger particles of dirt and dust is separated and then collected at the base 116 of the first cyclone 102.

Partially cleaned air stream then flows back into the inner space of the first cyclone 102 and exits through apertures in the casing 121. After the air stream passes through the casing 121, it enters the outlet 124 and there is shared between the tangential inlets 132 of each and the second cyclones 130. The diameter of each of the second cyclones 130 less than the diameter of the first cyclone 102, therefore, the second cyclones 130 is able to separate smaller particles of dirt and dust from the partially cleaned air stream than the first cyclone 102. The separated dirt and dust out of second cyclones 130 through conical holes 136. After that separated dirt and dust passes down the channel 138 and into the reservoir 142. The separated dirt and dust to settle on the bottom of the manifold 142 on the base 116.

Then the cleaned air is supplied again to the second cyclones 130, out of them through the outputs 134 and enters the tube 150. Next, the cleaned air leaves the tube 150, and sequentially passes through the motor filter 152, the motor fan unit and another filter before the release of the vacuum cleaner 10 through the air holes 24.

The first cyclone 102 and the collector 142 can be emptied simultaneously by opening the latches 120, resulting in the base 116 can be rotated around the hinges 118 and separated dirt and dust can fall out of the cyclone separator 100. This ensures an efficient and reliable removal of dirt and dust from the cyclone separator 100 at periodic intervals, convenient for the user.

The invention is not limited to the exact details described above variants of its implementation. For example, you may change the number of second C the clones, and the details of their design, such as the cone angle, the tilt axis and the slope of the tapered holes. The collected dirt and dust can be removed in other ways, such as complete removal of the bottom portion 102 may also vary and the location of the switch.
