DETAILED DESCRIPTION of EXEMPLARY embodiments of the INVENTION

Below with reference to pilage what's drawings are described in more detail with some exemplary embodiments of the present invention.

In the description below, in all the drawings to designate the same elements are the same item numbers. The objects specified in the description, such as detailed construction and elements are provided only to facilitate a comprehensive understanding of the invention. Thus, it is obvious that this invention can be made without specifying these objects. In addition, no detailed description of known functions or constructions, since the presence of excessive detail would confuse the invention.

Figure 1 is a perspective view of a vacuum cleaner made according to the approximate variant of execution of this invention.

The cleaner made according to the approximate variant of carrying out the invention contains the brush node 110, the receiver 120, the exhaust from the brush unit, a flexible hose 130, a case 140 of the vacuum cleaner and the node 150 of the handle.

Node 110 is in contact with the cleaned surface and extends from the surface of the dust-Laden air. Inverted dust-Laden air is passed into the housing 140 of the vacuum cleaner through the tube 120 extending from the node 110, and through a flexible hose 130. Site dust (not shown)mounted in the housing 140 of the vacuum cleaner, emit dust or other objects out of the air, venutolo through the node 110. In the housing 140 of the vacuum cleaner has a motor (not shown)designed to create a suction which subsequent efforts to draw dust-Laden air into the housing 140 of the vacuum cleaner through the node 110.

Node 150 of the handle is located between the tube 120 and a flexible hose 130. The user grasps the handle 170, available at node 150 of the handle, and manipulates the tube 120 and the host 110 to clean the surface.

Figure 2 is a view in axonometric node 150 of the handle in a disassembled state, Fig 3 is a longitudinal section of the node 150 arm, figure 4 is a top view in section of the node 150 of the handle.

Node 150 of the handle has a casing 160, the handle 170, the connecting node 180 and elastic node 190.

The casing 160 forms the outer part of the node 150 of the handle.

The handle 170 can be rotated in all directions, including left, right, up and down, and she can hold a user to move the vacuum cleaner.

Connecting node 180 connects the casing 160 with arm 170 that can rotate in all directions. Connecting node 180 is the axis 181 and the guide node 183.

Axis 181 passes through the handle 170 and the handle 170 can be rotated up or down around the axis 181.

Axis 181 is located in the pilot node 183 to rotate and guide the node 183 is located in the casing 160. Axis 181 slidable turns in the pilot site 183, and consequently the handle 170 can be rotated left and right.

Axis 181 and the guide node 183 to hold the handle 170 that provide the twist in all directions, including left, right, up and down. The above-described connecting node 180 in an exemplary embodiment of the present invention are given by way of example, but connecting node 180 may have different forms and is used only to attach the handle 170, so that it could be rotated in all directions, including left, right, up and down.

In view of the fact that the handle 170 is rotated in all directions, including left, right, up and down, the user can hold the handle 170, located in different positions without moving the tube 120. Thus, decreases the angle of flexion of the hand or elbow of the user when the cleaning. Consequently, the user is less anxious and experiencing less discomfort when using the tube 120.

Elastic node 190 elastically pressed the lever 170 in the neutral position. In the neutral position, the handle 170 can't turn in any direction and is located in the center of the casing 160. That is, if the lever 170 is in the neutral position, the resultant force exerted by the node 190 of the handle 170, equal to zero. Node 190, performed according to an exemplary variant of implementation of the present invention, has four elastic element 191, 192,193 and 194, which are in contact with the handle 170.

If the handle 170 is rotated upward, the elastic element 191 elastic is about pressing the handle 170 to the neutral position, if the handle 170 is rotated downward, the elastic element 192 elastically pressed the handle 170 to the neutral position when the handle 170 is rotated to the left, the elastic element 193 elastically pressed the handle 170 to the neutral position, and when the handle 170 is rotated to the right, the elastic element 194 elastically pressed the handle 170 to the neutral position.

In an exemplary embodiment of the present invention, the elastic elements 191, 192, 193 and 194 are made in the form of leaf springs. However, it should be taken into account that this invention is not limited to these configurations, and in an alternative embodiment, the elastic elements 191, 192, 193 and 194 may be a torsion spring or a compression spring.

Figure 5 is a view in axonometric node handle, made according to an exemplary variant of implementation of the present invention, in a disassembled state. Node 150 of the handle presented on figure 5, is essentially the same as the node 150 of the handle, are presented in figure 2, except that the node 150 of the handle presented on figure 5, further comprises a flange 182, performed at both ends of the axis 181. The cross-section of the flange 182 corresponds to the guiding node 183 and, thus, the flange 182 may be inserted into the guide node 183 and has the possibility of sliding in the specified node. Since the flange 182 can slide napravlyaem node 183, and the axis 181 can be rotated, arm 170 has the ability to move left and right.

6 is a top view illustrating the position of the vacuum cleaner made according to the approximate variant of implementation of the present invention, in the process.

As can be seen from Fig.6, the handle 170 is rotated left and right, so the user can easily perform cleaning of corners (A). If the handle 170 was still attached to the tube 120, to perform cleaning of the angle (A), the user would have to move your hand in the position shown by dashed line. However, since the arm 170 of the vacuum cleaner made according to the approximate variant of implementation of the present invention, can be rotated left and right, the user has no need to move to the corner (A). Using a vacuum cleaner made according to the approximate variant of implementation of the present invention, the user can easily manipulate the tube 120.

Fig.7 is a side view illustrating a vacuum cleaner, presented in figure 1, in the process.

As can be seen from Fig.7, the user must vigorously move the tube 120 in order to perform cleaning of the angle (In). If the handle 170 was still attached to the tube 120, the user would have to bend my wrist or elbow in an awkward position. However, recoat is and 170 of the vacuum cleaner, performed according to an exemplary variant of implementation of the present invention, can be rotated up and down. Therefore, even if the tube 120 is tilted limit angle, the angle between the handle 170 and the surface being cleaned is changed slightly. That is, the angle θ1between the handle 170 and the surface being cleaned, formed in the position of the brush unit, marked by a solid line, is approximately equal to the angle θ2between the handle 170 and the cleaned surface formed at the position of the brush unit, indicated by the dashed line. Thus, the user conveniently to perform cleaning of the angle (In), essentially without changing the position of the hand or elbow.

According to the site handles approximate variant of implementation of the present invention the handle is rotated in all directions, including left, right, up and down. Thus, the brush or the elbow of the user is bent at a slight angle, and the user feels less tension in the joints.

Accordingly, the user can easily manipulate the handle by its rotation.

At process of cleaning changing characteristics of compressed air pulses, orientation and shape of air streams while changing frequency of compressed air pulses, their duty factor, amplitude of flow rate and pressure of compressed air according to condition providing maximum activation of dust without damaging members. Pulses of compressed air flows are applied by bursts during phase of dust activation. At cleaning process number of pulses in bursts, shape, duty factor, frequency of pulses, duty factor of pulse bursts are changed according to condition providing maximum rate of dust activation for cleaned surface. 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.
