Description

Technical Field

[0001] The utility model relates to household appliances, in particular to a dust collection device. Background Art

[0002] The existing dust collection device mainly consists of a vacuum cleaner and a garbage recycling station. During cleaning, the vacuum cleaner can be removed from the garbage recycling station and used separately. After use, the vacuum cleaner is reinstalled on the garbage recycling station, and the garbage and dust inside the vacuum cleaner can be cleaned through the garbage recycling station. For example, the utility model patent with the publication number CN219229728U discloses a dust collection device, including a vacuum cleaner and a recycling station. The vacuum cleaner includes a housing, a suction nozzle, a dust bin, an air suction channel, a filtering component, a dust suction motor and an exhaust channel arranged inside the housing. The suction nozzle is communicated with the dust bin through the air suction channel. The filtering component is arranged between the dust bin and the dust suction motor. The exhaust channel is located downstream of the filtering component and communicated with the outside of the vacuum cleaner. The recycling station recycles the garbage in the dust bin to the recycling station through the air suction channel. The housing is provided with an air inlet communicated with the exhaust channel, and an air inlet cover for keeping the air inlet normally closed is arranged on the outer side of the housing. The recycling station is provided with a pushing member, and the pushing member acts on the air inlet cover after the vacuum cleaner is received in the recycling station, so that the air inlet cover is opened outwards to open the air inlet. The specific use process is as follows: After the vacuum cleaner is received in the garbage recycling station, the sealing protrusion cooperates with the opening of the suction nozzle to seal the suction nozzle. The housing acts on the trigger point to start the recycling motor of the garbage recycling station. The pushing member acts on the air inlet cover to open the air inlet cover outwards. The air flow enters from the air inlet hole and sequentially passes through the exhaust channel, the filtering component and the dust bin. Then the air flow pushes open the check valve to bring the garbage in the dust bin into the air suction channel, and then is input from the discharge port to the recycling port and sent to the garbage recycling station for recycling.

[0003] In the above-mentioned dust collection device, since the air inlet is located downstream of the filtering component, during the operation of the garbage recycling station, the filtering component can be back-blown and dusted, thereby preventing the filtering component from being blocked. However, the back-blowing air flow impacts the filtering component for a long time, which is likely to cause the filter holes on the filtering component to become larger, thus affecting the filtering accuracy and service life of the filtering component. Therefore, it still needs to be improved. Summary of the Utility Model

[0004] Aiming at the shortcomings of the existing technology, the utility model provides a dust collection device. The air flow entering the housing of the vacuum cleaner through the air inlet can directly blow the outer wall of the filtering component, which can not only clean the garbage and dust attached to the filtering component, but also prevent the filter holes on the filtering component from becoming larger, thereby prolonging the service life of the filtering component.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A dust collection device includes a vacuum cleaner and a garbage recycling station. The vacuum cleaner includes a housing and a filter assembly disposed inside the housing. The garbage recycling station is used to accommodate the vacuum cleaner and recycle the garbage inside the vacuum cleaner. An air inlet communicating with the inner cavity of the housing is provided on the side wall of the housing. An air inlet cover for keeping the air inlet normally closed is provided outside the housing. The garbage recycling station is provided with a pushing member. When the vacuum cleaner is accommodated in the garbage recycling station, the pushing member acts on the air inlet cover to open the air inlet outward. The air inlet is directly opposite to the side surface of the filter assembly. When the air inlet cover is opened outward, the airflow entering the housing through the air inlet cover can blow and remove dust from the outer side wall of the filter assembly.

[0007] With the above solution, when the vacuum cleaner is accommodated in the garbage recycling station, the pushing member on the garbage recycling station can drive the air inlet cover to open outward, so that the air inlet is opened. At this time, the airflow outside the vacuum cleaner can enter the interior of the housing of the vacuum cleaner through the air inlet to blow and remove dust from the outer side wall of the filter assembly. In this way, it can not only clean the garbage and dust adsorbed on the filter assembly, but also prevent the pores of the filter assembly from expanding, thereby prolonging the service life of the filter assembly.

[0008] Preferably, one end of the air inlet cover is pivotally connected to one side of the air inlet and the rotation plane is perpendicular to the direction of the airflow inside the housing. When the air inlet cover is opened outward, the airflow can enter the air inlet tangentially; an elastic member for driving the air inlet cover to close the air inlet is provided between the air inlet and the air inlet cover.

[0009] With the above solution, when the air inlet cover is opened outward, it can form a tangential opening at the air inlet to guide the airflow to enter the air inlet transversely, so as to drive the airflow to circle around the periphery of the filter assembly, thereby improving the efficiency and uniformity of blowing and dust removal. The elastic member can make the air inlet cover have a tendency to close the air inlet, thus realizing the normally closed function of the air inlet cover.

[0010] Preferably, a pushed convex member for being squeezed by the pushing member to drive the air inlet cover to turn outward is provided at the pivotally connected end of the air inlet cover.

[0011] With the above solution, by squeezing the pushed convex member on the air inlet cover with the pushing member, the air inlet cover can be quickly driven to open outward and the stability after opening can be ensured.

[0012] Preferably, an avoidance groove for accommodating the opened air inlet cover is provided on the outer side of the garbage recycling station.

[0013] With the above solution, the avoidance groove can allow the air inlet cover on the housing of the vacuum cleaner to be opened smoothly, thus ensuring the smooth operation of the garbage recycling station.

[0014] Due to the adoption of the above technical solutions, the utility model has remarkable technical effects: when the vacuum cleaner is stored in the garbage recycling station, the pushing member on the garbage recycling station can drive the air inlet cover to open outwards, so that the air inlet is opened. At this time, the air flow outside the vacuum cleaner can enter the interior of the outer shell of the vacuum cleaner through the air inlet to blow and dust the outer side wall of the filter assembly. In this way, it can not only clean the garbage and dust adsorbed on the filter assembly, but also prevent the filter holes of the filter assembly from expanding, thereby extending the service life of the filter assembly.

[0025] The present utility model will be further described in detail below with reference to the drawings and embodiments.

[0026] AsFigures 1 to 7 As shown in the figure, a dust collection device disclosed in this embodiment includes a vacuum cleaner 1 and a garbage recycling station 2. The vacuum cleaner 1 includes a housing 3, a suction nozzle 11, a dust bin 12, an air suction channel 13, a filtration component 4, a dust collection motor 14, and an exhaust channel 15 disposed inside the housing 3. The suction nozzle 11 is communicated with the dust bin 12 through the air suction channel 13. The filtration component 4 is disposed between the dust bin 12 and the dust collection motor 14. The exhaust channel 15 is located downstream of the filtration component 4 and is communicated with the outside of the vacuum cleaner 1. The garbage recycling station 2 is used to receive the vacuum cleaner 1 and recycle the garbage in the dust bin 12. The garbage recycling station 2 recycles the garbage in the dust bin 12 to the garbage recycling station 2 through the air suction channel 13. An air inlet 5 communicating with the inner cavity of the housing 3 is formed in the side wall of the housing 3. An air inlet cover 6 for keeping the air inlet 5 normally closed is provided on the outside of the housing 3. The garbage recycling station 2 is provided with a pushing member 7. When the vacuum cleaner 1 is received in the garbage recycling station 2, the pushing member 7 acts on the air inlet cover 6 to drive the air inlet cover 6 to open the air inlet 5 outward. The air inlet 5 is directly opposite to the side surface of the filtration component 4. When the air inlet cover 6 is opened outward, the airflow entering the housing 3 through the air inlet cover 6 can blow and remove dust on the outer side wall of the filtration component 4. In this way, it can not only clean the dust and garbage adsorbed on the filtration component 4, but also avoid the expansion of the filter holes on the filtration component 4, thereby prolonging the service life of the filtration component 4.

[0027] As Figure 8 and Figure 9 shown in the figure, in order to improve the cleaning effect of the filtration component 4, one end of the air inlet cover 6 is pivotally connected to one side of the air inlet 5 through a hinge 16, and the rotation plane is perpendicular to the direction of the airflow inside the housing 3. In this embodiment, when the air inlet cover 6 is opened outward, the airflow can enter the air inlet 5 tangentially. An elastic member 8 for driving the air inlet cover 6 to close the air inlet 5 is disposed between the air inlet 5 and the air inlet cover 6. The elastic member 8 is preferably a torsion spring, one end of which is fixed to the pivoting end of the air inlet cover 6, and the other end is fixed to the side wall of the air inlet 5, thereby realizing the elastic reset function of the air inlet cover 6.

[0028] As Figure 6 and Figure 9 shown in the figure, a pushed convex member 9 for being squeezed by the pushing member 7 to drive the air inlet cover 6 to turn outward is disposed at the pivoting end of the air inlet cover 6. An avoidance groove 10 for accommodating the opened air inlet cover 6 is formed on the outside of the garbage recycling station 2.
