Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, and more specifically, to a vacuum cleaner for cleaning filters. Background Art

[0002] In the design of modern vacuum cleaners, filters play a crucial role. Their main function is to effectively filter the particulate matters such as sundries and dust inhaled by the vacuum cleaner during operation, ensuring that the discharged air is clean and avoiding secondary pollution. However, with the frequent use of the vacuum cleaner, the filter will gradually be blocked by dust and sundries. If the filter is not cleaned in time, its filtering effect will be significantly reduced, which will not only cause the suction of the vacuum cleaner to weaken, affecting its overall performance, but also may increase the load on the blower, shortening the service life of the vacuum cleaner. Therefore, how to improve the cleanliness and maintenance convenience of the filter has become the key to improving the performance of the vacuum cleaner and the user experience. Summary of the Invention

[0003] The utility model aims to solve one of the technical problems in the related technologies to a certain extent. For this purpose, the utility model provides a vacuum cleaner for cleaning filters, which realizes the automatic cleaning function of the filter through valve switching, avoids manual disassembly, improves the cleaning efficiency and extends the service life of the vacuum cleaner.

[0004] The technical solution adopted by the utility model is as follows: a vacuum cleaner for cleaning filters is provided, which includes a body, a filter, a dust collection bucket, a blower providing suction power, and a valve. The valve moves between a first position and a second position. A cleaning air duct and an exhaust hole are provided on the body. The cleaning air duct is used to apply the inflowing air to the outside of the filter.

[0005] Wherein, when the valve is in the first position, the valve connects the air outlet end of the blower, the exhaust hole and the external space of the vacuum cleaner, and blocks the passage between the air outlet end of the blower and the cleaning air duct.

[0006] When the valve is in the second position, the valve connects the air outlet end of the blower and the cleaning air duct, and blocks the passage between the air outlet end of the blower and the exhaust hole.

[0007] After adopting the above structure, when it is necessary to clean the filter, the user only needs to switch the valve to the second position. The blower will inhale air from the outside through the cleaning air duct and apply it to the outside of the filter. At this time, the dust and sundries on the filter will be effectively removed under the action of the air flow and sent into the dust collection bucket, thus realizing the function of automatically cleaning the filter.

[0008] After cleaning is completed, the user can switch the valve back to the first position to restore the normal working state of the vacuum cleaner. With this design, the user does not need to frequently manually disassemble and clean the filter, which not only improves the cleaning efficiency but also reduces the maintenance cost. At the same time, since the filter always remains in the optimal working state, the suction power of the vacuum cleaner is kept stable, extending the service life of the device.

[0009] According to an embodiment of the present invention, the body includes a top cover and a housing, and the fan is disposed in the space enclosed by the top cover and the housing.

[0010] According to an embodiment of the present invention, the housing is provided with the exhaust hole, and the exhaust hole is used to communicate the air outlet end of the fan with the external space of the vacuum cleaner. When the valve is in the second position, the exhaust hole is blocked.

[0011] According to an embodiment of the present invention, the valve has a first sealing portion corresponding to the exhaust hole, and the first sealing portion is used to block or open the exhaust hole; when the valve is in the first position, the first sealing portion is open, allowing air to be discharged through the exhaust hole, while the second sealing portion is blocked, preventing air from entering the cleaning air duct. When the valve is in the second position, the first sealing portion is blocked, preventing air from being discharged through the exhaust hole, while the second sealing portion is open, allowing air to enter the cleaning air duct to clean the filter.

[0012] According to an embodiment of the present invention, the body further includes an air duct housing, and the air duct housing and the top cover enclose to form the cleaning air duct.

[0013] According to an embodiment of the present invention, the top cover has a plurality of cleaning air holes for applying the air in the cleaning air duct to the outside of the filter; the cleaning air holes are spaced around the outer periphery of the filter, so that the cleaning air flow can evenly cover the entire outer surface of the filter, thereby ensuring that dust and debris in all areas of the filter can be effectively removed. The spaced distribution of the cleaning air holes can also reduce the eddy current and dead angle of the air flow outside the filter, improve the cleaning efficiency, and avoid the problem of incomplete cleaning.

[0014] According to an embodiment of the present invention, the air duct housing is provided with a cleaning hole, and the cleaning hole is used to communicate the cleaning air duct with the air outlet end of the fan. When the valve is in the first position, the cleaning hole is blocked.

[0015] According to an embodiment of the present utility model, the valve has a second sealing portion corresponding to the cleaning hole, and the second sealing portion is used to block or open the cleaning hole; the design of the second sealing portion ensures that when the valve is switched to the first position, the cleaning hole is completely blocked, preventing air flow from entering the cleaning air duct by mistake, thereby ensuring the normal exhaust function of the vacuum cleaner. When the valve is switched to the second position, the second sealing portion opens the cleaning hole, enabling the air outlet end of the fan to communicate with the cleaning air duct, and the air flow can enter the cleaning air duct through the cleaning hole and act on the filter to achieve automatic cleaning of the filter.

[0016] According to an embodiment of the present utility model, the top cover is provided with a first spring groove, the valve is provided with a second spring groove, one end of an elastic member is connected to the first spring groove, and the other end of the elastic member is connected to the second spring groove.

[0036] As Figure 1-8 shown, in this embodiment, a filter 20 cleaning vacuum cleaner is disclosed, which includes a body 10, a filter 20, a dust collection bucket 30, a fan 14 providing suction power, and a valve 16. The valve 16 is movable between a first position and a second position. The body 10 is provided with a cleaning air duct 15a and an exhaust hole 13a. The cleaning air duct 15a is used to apply the inflowing air to the outside of the filter 20;

[0037] Wherein, when the valve 16 is in the first position, the valve 16 communicates the air outlet end of the fan 14, the exhaust hole 13a with the external space of the vacuum cleaner, and blocks the passage between the air outlet end of the fan 14 and the cleaning air duct 15a;

[0038] When the valve 16 is in the second position, the valve 16 communicates the air outlet end of the fan 14 with the cleaning air duct 15a, and blocks the passage between the air outlet end of the fan 14 and the exhaust hole 13a.

[0039] Further, in combination with Figure 3 .7 and Figure 8 As shown in Figure 8 , in this embodiment, the valve 16 is floatingly mounted on the body 10. The valve 16 has a first sealing portion 16a and a second sealing portion 16b. The first sealing portion 16a and the second sealing portion 16b are spaced apart and are integrally connected by a connecting portion 16d. That is, one end of the rod-shaped connecting portion 16d is connected to the first sealing portion 16a, and the other end is connected to the second sealing portion 16b. A second spring groove 16c is provided at the bottom of the second sealing portion 16b.

[0040] Furthermore, in this embodiment, the body 10 includes a housing 11, a top cover 12, and a casing 13. The top cover 12 is detachably connected to the dust collection bucket 30 and forms a dust collection chamber. The dust collection bucket 30 is connected by a hose to a handle with a suction port. The filter 20 is detachably mounted at the bottom of the top cover 12. The blower 14 that provides suction power has an air inlet end and an air outlet end. The air inlet end communicates with the dust collection chamber through the filter 20. The negative pressure in the dust collection bucket 30 sucks external dust from the suction port on the handle into the dust collection chamber, and the dust passing through the filter 20 stays in the dust collection chamber. Correspondingly, the air outlet end of the blower 14 discharges the flowing air to the outside.

[0041] Specifically, the body 10 includes a top cover 12 and a casing 13. The blower 14 is disposed in the space surrounded by the top cover 12 and the casing 13. The casing 13 is provided with the exhaust hole 13a, and the exhaust hole 13a is used to communicate the air outlet end of the blower 14 with the external space of the vacuum cleaner. When the valve 16 is in the second position, it blocks the exhaust hole 13a. The valve 16 has a first sealing portion 16a corresponding to the exhaust hole 13a, and the first sealing portion 16a is used to block or open the exhaust hole 13a. The body 10 further includes an air duct housing 15, and the air duct housing 15 and the top cover 12 surround and form the cleaning air duct 15a. The top cover 12 has a plurality of cleaning air holes 12a for applying the air in the cleaning air duct 15a to the outside of the filter 20.

[0042] Furthermore, in combination with Figure 4 As shown in Figure 4 , the air duct housing 15 is fixedly connected to the top cover 12 and forms an annular cleaning air duct 15a. A circle of cleaning air holes 12a is provided on the top cover 12 in the cleaning air duct 15a. The inner diameter of the distribution of the cleaning air holes 12a is greater than the outer diameter of the filter 20. In this embodiment, the blower 14 and the filter 20 are coaxially distributed, and the cleaning air holes 12a are annularly distributed around this axis.

[0043] Furthermore, in combination with Figure 6As shown, the air duct housing 15 is provided with a cleaning hole 15b. The cleaning hole 15b is used to communicate the cleaning air duct 15a with the air outlet end of the blower 14. When the valve 16 is in the first position, it blocks the cleaning hole 15b. The valve 16 has a second sealing portion 16b corresponding to the cleaning hole 15b. The second sealing portion 16b is used to block or open the cleaning hole 15b. The top cover 12 is provided with a first spring groove 12b, and the valve 16 is provided with a second spring groove 16c. One end of an elastic member 17 is connected to the first spring groove 12b, and the other end of the elastic member 17 is connected to the second spring groove 16c. The body 10 further includes a housing 11. The housing 11 has a mounting hole 11a. One end of the valve 16 is slidably engaged with the mounting hole 11a.

[0044] Further, in this embodiment, the elastic member 17 is a helical spring.
