DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Figure 1 FIG. is a schematic structural diagram of an automatic dust cleaning device for a vacuum cleaner filter element provided by an embodiment of the present utility model, Figure 2 FIG. is a schematic structural diagram of the automatic dust cleaning device for a vacuum cleaner filter element provided by an embodiment of the present utility model after being installed at the vacuum cleaner filter element.

[0025] As Figure 1As shown in the figure, the automatic dust cleaning device for the vacuum cleaner filter element provided by the embodiment of the present utility model includes a vibration assembly 1 and a knocking assembly 2. The vibration assembly 1 includes a vibration driving member 11 and a vibration mounting portion 12. The vibration driving member 11 is fixedly mounted on the filter element 31 through the vibration mounting portion 12. The knocking assembly 2 includes a knocking driving member 21, a knocking connecting member 22 and a knocking member 23. The knocking connecting member 22 is connected to the output end of the knocking driving member 21, and the knocking member 23 is mounted inside the filter element 31 through the knocking connecting member 22.

[0026] The vibration driving member 11 outputs vibration power, and the vibration mounting portion 12 fixedly mounted on the filter element 4 conducts the vibration power to the filter element 31, so that the filter element 31 vibrates with the vibration driving member 11, and the dust and other sundries adsorbed on the filter element 31 can, when moving with the filter element, break away from the filter element 31 under the action of inertia, thereby cleaning the filter element 31. By the knocking driving member 21 outputting knocking power, the knocking connecting member 22 and the knocking member 23 move relative to the filter element inside the filter element 31, so that the knocking member 23 knocks on the inner wall of the filter element 31. The wall body of the filter element 31 generates local instantaneous high-speed vibration movement after being knocked, so that the sundries adsorbed on the corrugated outer surface of the filter element 31 fall off, improving the cleaning effect on the filter element 31.

[0027] By applying vibration and knocking actions to the filter element 31 through the vibration assembly 1 and the knocking assembly 2 installed inside the vacuum cleaner, the sundries adsorbed outside the filter element 31 can be effectively cleaned, without the need to manually clean the filter element after removing it additionally, improving work efficiency.

[0028] In one preferred embodiment, the vibration mounting portion 12 is fixedly connected to a plurality of positions distributed at intervals along the circumference inside the filter element 31.

[0029] As Figure 2 shown, the knocking assembly 2 further includes a knocking mounting portion 24. One end of the knocking mounting portion 24 is mounted on the filter element mounting seat 32, and the other end is located inside the filter element 31. The knocking driving member 21 is mounted inside the filter element 31 through the knocking mounting portion 24, which can reduce the amplitude of the knocking assembly 2 shaking together with the vibration driving member 11 and improve the installation stability of the knocking assembly 2. The knocking mounting portion 24 can also be partially overlapped with the vibration mounting portion 12. When the vibration driving member 11 outputs vibration power, the knocking member 23 in the knocking assembly 2 also vibrates, and when vibrating, it knocks on the inner wall of the filter element 31, which can further increase the relative movement speed of the knocking member 23 and the filter element 31, thereby increasing the impact force of the knocking member 23 knocking on the filter element and improving the cleaning effect.

[0030] In one preferred embodiment, the knocking power output by the knocking driving member 21 is a rotational power. The rotational axis of the output end of the knocking driving member 21 coincides with the axis of the filter element 31. One end of the knocking member 23 is connected to the knocking connecting member through an elastic element 231. The end of the knocking member 23 away from the knocking connecting member 22 extends into the folds on the inner wall of the filter element 31. When the knocking driving member 21 outputs rotational power, the knocking connecting member 22 drives the knocking member 23 to rotate around the axis of the filter element 31, causing an interaction force at the part where the knocking member 23 contacts the folds, further causing the elastic element 231 to undergo elastic deformation. Under the action of the rotational power and the elastic force, the knocking member 23 can spring into the fold gap and knock against and press on the folds.

[0031] Among them, the vibration driving member 11 can adopt electric vibration driving or pneumatic vibration driving, etc., and can output stable and strong vibration power; the knocking driving member 21 can adopt a rotating motor, and the knocking connecting member 22 is fixedly connected to the output end of the rotating motor; the elastic element 231 can adopt a spring, a elastic rod, etc.

[0032] In addition, it is also possible to set the power output by the knocking driving member 21 as the force for driving the knocking member 23 to reciprocate radially along the filter element 31. An air cylinder or an electric telescopic cylinder, etc. is used as the knocking driving member 21. The knocking driving member 21 drives the knocking member 23 towards the center of the filter element 31, and then drives the knocking member 23 close to the inner wall of the filter element 31, so that the knocking member 23 hits the inner wall of the filter element 31, and the effect of cleaning the filter element 31 can also be achieved.

[0033] Figure 3 is a schematic structural diagram of another perspective of the automatic dust cleaning device for the vacuum cleaner filter element provided by an embodiment of the present invention.

[0034] As Figure 1 shown in Figure 3 In one preferred embodiment, the knocking connecting member 22 includes a first part 221 connected to the knocking driving member 21, and a second part 222 formed by the first part 221 extending axially along the filter element 31. The knocking member 23 is installed on the second part 222. Among them, the first part 221 and the second part 222 can be a detachable connection as Figure 1 shown, or a fixed connection such as welding or integral molding.

[0035] In one preferred embodiment, a plurality of knocking members 23 can be arranged at intervals along the axis of the filter element 31 on the second part 222 to knock on multiple parts inside the filter element 31 and improve the cleaning effect on the filter element 31. Further, as Figure 1 shown in Figure 3As shown, the output end of the knocking driving member 21 can be set at the inner bottom of the filter element 31. Correspondingly, the first part 221 is also located at the inner bottom of the filter element 31, so that the second part 222 is formed by extending upward along the axis from the bottom of the filter element 31. The height of the second part 222 is close to the axial length of the filter element 31. After installing a plurality of knocking members 23 at intervals on the second part 222, the filter element 31 can be more comprehensively covered, improving the cleaning effect on the filter element 31.

[0036] As Figure 1 shown Figure 3 As shown, the knocking members 23 arranged on the second part 222 can be distributed along a spiral line, and this spiral line is a spiral line centered on the axis of the filter element 31. That is, a plurality of knocking members 23 penetrate into a plurality of folds distributed at intervals along the circumferential direction of the filter element 31, so as to simultaneously knock on a plurality of folds inside the filter element 31, enabling the filter element 31 to be fully and evenly knocked, improving the cleaning effect on the filter element.

[0037] In one preferred embodiment, an adjusting device 223 can be arranged on the second part 222, and the adjusting device 223 can adjust the installation position of the knocking member 23 on the second part 222.

[0038] Specifically, as Figure 3 shown, it can be set that the adjusting device 223 includes an oblong installation groove opened on the second part 222. Adjusting threaded holes are opened on both sides of the installation groove, and adjusting screws are inserted into the adjusting threaded holes on both sides thereof. The adjusting screws are in threaded cooperation with the first threaded holes. An adjusting part is clamped between the ends of the two adjusting screws. The knocking member 23 is installed on the adjusting part through an elastic element 231. By adjusting the length of the parts of the adjusting screws on both sides of the installation part screwed into the installation groove, the adjusting part can be reciprocally moved along the axial direction of the screws, that is, moved along the installation groove, so as to adjust the installation position of the knocking member 23 on the second part 222. Specifically, when it is necessary to drive the adjusting part to move to the left in the installation groove, the adjusting screw on the left side of the adjusting part is loosened and screwed out of the installation groove by a certain length, so that there is a space for movement on the left side of the adjusting part. Subsequently, the adjusting screw on the right side of the adjusting part is screwed into the installation groove by a certain length, so that the two adjusting screws tightly press the adjusting part here, that is, the adjustment of the position of the adjusting part is completed.

[0039] Furthermore, recessed grooves can be opened at the parts on both sides of the adjusting part in contact with the ends of the adjusting screws, and the ends of the adjusting screws extend into the recessed grooves and press against the bottom of the recessed grooves, making the clamping of the two adjusting screws on the adjusting part more stable.

[0040] In addition, an installation groove may be formed in the second part 222. The adjusting part is arranged on the outer side of the second part 222 close to the inner wall of the filter element. An elastic element 231 and a knocking part 23 are installed on the side of the adjusting part away from the second part 222. A screw rod is installed on the side of the adjusting part close to the second part 222. The screw rod passes through the installation groove, and an internally threaded block is sleeved on the screw rod on the other side of the installation groove. The outer dimension of the adjusting part and the outer dimension of the internally threaded block are both larger than the installation groove. When the internally threaded block is tightened, the internally threaded block and the adjusting part can be clamped on the second part 222 outside the installation groove, so as to fix the knocking part 23 on the second part 222. By loosening the internally threaded block, the screw rod on the adjusting part can move along the installation groove, so as to adjust the installation position of the knocking part 23 on the second part 222.

[0041] It should be noted that the above is only a preferred technical solution that can realize the function of adjusting the installation position of the knocking part 23 on the second part 222, rather than all technical solutions. As long as the installation position of the knocking part 23 is adjusted by the adjusting device, it should be regarded as within the protection scope of the present utility model.

[0042] By adjusting the installation position of the knocking part 23 on the second part 222 through the adjusting device 223, the knocking part 23 can penetrate into different folds along the circumferential direction of the filter element 31, so that more positions inside the filter element 31 are knocked, and the cleaning effect on the filter element 31 is improved.

[0043] In one preferred embodiment, the first part 221 of the knocking connecting part 22 is provided with at least two branches, and at least two branches meet at the output end of the knocking driving part. According to the number of branches of the first part 221, it forms a "one" shape, a "person" shape, a "ten" shape, a "*" shape or even a "rice" shape, etc. The second part 222 is installed at the end of each branch of the first part 221, and the knocking part 23 is installed on the second part 222. By increasing the number of the first part 221 and the second part 222 arranged inside the filter element 31, the number of the knocking parts 23 can be increased, so that the inner wall of the filter element 31 is knocked more fully, and the cleaning effect on the filter element is improved. Among them, the first part 221 and the second part 222 can be detachably connected by screws as shown in Figure 1 and Figure 3 shown, or can be integrally formed.

[0044] The present utility model also provides a vacuum cleaner, in which the above-mentioned filter element cleaning device is installed at the filter element of the vacuum cleaner, and the filter element of the vacuum cleaner is automatically cleaned through the filter element cleaning device, so that the use of the vacuum cleaner is more durable and convenient.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit them. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that any modification or equivalent replacement of the technical solutions of the present utility model does not depart from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
