Detailed description of the invention

Below with reference to the accompanying drawings described first and second exemplary embodiments of the present invention.

As can be seen from figure 2 and figure 3, the suction nozzle 100, made in accordance with the first exemplary embodiment of the present invention contains the activator 200 located rotatably within the housing 110 of the suction nozzle.

Suction nozzle 100 has a suction hole 120. For connection to the suction hole 120 with the extension tube includes a connector, so that the suction hole 120 is communicated with the main body of the vacuum cleaner (not shown).

Activator 200 includes a housing 210 and a blower device 223.

The housing 210 activator has a cylindrical configuration, and the outer periphery of the housing has bristles 201. The bristles 201 can be located essentially parallel to the axis of the housing 210 activator (figure 2 and figure 4), or alternatively can be located on the sine wave (figure 1).

Blower device 223 has a first and second blower nodes 221 and 222, performed at both ends of the housing 210 activator, and dedicated to superior quality products is expected to generate air flow in the space (S), formed between the inner side of the housing 110 of the suction nozzle and the outer side of the housing 210 activator.

The first and second blower nodes 221 and 222 are of arcuate guides the blades are located at intervals along the outer periphery of the housing 210 activator. The first and second nodes 221 and 222 can be implemented as a single unit with the housing 210, or alternatively, may be made separately and attached to the chassis 210.

While the first and second blower nodes 221 and 222 having arcuate guides blades, curved in opposite directions, forcing the air to move from both ends of the suction nozzle 100 toward the center, which performed the suction hole 120. Therefore, as the rotation of the activator 200 air in the space (S)formed between the inner side of the housing 110 of the suction nozzle and the outer side of the activator 200 is sent from the ends of the suction nozzle 100 to the center. In accordance with this air flow dust particles swept from the working surface near the two ends of the suction nozzle 100, successfully moved to the hole 120.

Despite the fact that the first node 221, presented in figure 3, has four arcuate guides the blades situated essentially at right angles, it is suitable for the em approximate variant of implementation of the present invention. Accordingly, if necessary, can be performed in two, three, four or more than four arcuate guide blades. Although not shown, the second node 222 is made symmetrically on the opposite end of the activator 200. The first and second nodes 221 and 222 may have different designs, provided that they are made on both ends of the activator 200, forming an air stream directed to the hole 120.

Figure 4 and figure 5 shows the suction nozzle 100'having the activator 200', performed according to the second exemplary variant implementation of the invention.

Activator 200'having a blower device 223', which made directing blades, is located in the suction nozzle 100' with the possibility of rotation.

Suction nozzle 100' has a suction hole 120', made approximately in the center, and an extension tube (not shown) connected with the suction hole 120' to supply vacuum to the suction nozzle 100' vacuum cleaner, vacuum formed by the engine main body of the vacuum cleaner (not shown). The above elements of the second exemplary variant of implementation of the present invention virtually the same as the elements described in the first embodiment.

Activator 200' includes a housing 210' and blower unit 223'. In the activator 200' made bristles 201.

Blower device is istwo 223' has first and second blower nodes 221' and 222', which can be made in the form of curved guiding vanes curved in the opposite direction relative to the suction hole 120'.

As can be seen from the expanded image presented on figure 5, the first and second nodes 221' and 222' are set at the same intervals as in the direction of the axis of the housing 210' activator, and in the direction perpendicular to the axis of the housing 210' of the activator. As a result, when the rotation of the activator 200' are formed oppositely directed streams of air.

Considering the fact that the first and second nodes 221' and 222' are designed to facilitate the flow of air from both ends of the suction nozzle 100' toward the suction hole 120', and in places, facing to the suction hole 120', there is no need to create a stream of air, these nodes 221' and 222' can not be performed at the locations facing to the suction hole 120' body 210' of the activator.

Moreover, it is desirable that the first and second nodes 221' and 222' were located, not touching the bristles 201. If the first and second nodes 221' and 222' touch the bristles 201, the bristles 201 may prevent air flow between the first and second nodes 221' and 222', or the first and second nodes 221' and 222' can prevent the collision of the bristles 201 with the working surface.

Figure 6 compares the efficacy of conventional activator and efficiency is the efficiency of the activator 200', performed according to an exemplary variants of execution of the present invention. In particular, figure 6 shows the pattern in the left part of which is made of conventional activator, whereas on the right made the activator performed according to the second exemplary variant implementation of the invention.

When you start cleaning with the use of the suction nozzle, dust particles, under the setae on the left, with difficulty moved to the suction hole, while having in the right side of blower unit 223', dust particles, under the bristles 201, move quickly to the hole 120' in the air formed by the device 223', so that dust particles do not accumulate in the right part of the suction nozzle.

Although not shown, the suction hole 120 or 120' may be located in the Central part, and be located closer to one or the other end of the suction nozzle 100 or 100', depending on the specific goals set by the developer. In this case, the air-blowing device 223' may be not necessarily around the suction hole 120 or 120' activator 200.

Novelty is feed of train of short pulses in phase of dust activation before feeding one long pulse in order to create pulsating flows of compressed air providing pressure drop. It allows accelerate dust particle tearing from surface due to creation of pulsating turbulent air flows near cleaned surface. Dust-laden air is sucked by means of pulses of directed suction flows of air. Method may be used in home and industrial rooms for cleaning complex-profile surfaces.

EFFECT: enhanced quality and rate of cleaning complex-profile articles.
