[0034] refer to Figure 2-9, a vacuum cleaner 101 is disclosed in the figure. The vacuum cleaner 101 includes a main body 1 and a dust cup assembly 2 arranged on the main body 1. The main body 1 includes a shell 11, and the shell 11 defines a storage space. A suction motor 12 can be arranged in the storage space, and the suction motor 12 can generate a suction airflow. A battery pack can also be installed on the main body 1, and the suction motor 12 is powered by the battery pack. A circuit board (controller) is also arranged in the main body 1, and the suction motor 12 is controlled by the circuit board. The above structure is relatively common in the prior art and will not be described in detail here. The dust cup assembly 2 is detachably mounted on the main body 1, or the dust cup assembly 2 cannot be removed from the main body 1, or only a part of the structure of the dust cup assembly 2 can be removed from the main body 1, for example: only the filter is removed or only the dust cup shell 11 is removed. An annular filter screen 21 is arranged in the dust cup. The overall shape of the annular filter screen 21 is cylindrical. The side of the annular filter 21 is covered with filter holes or only part of the surface of the annular filter 21 is provided with filter holes. After the airflow enters the internal space defined by the dust cup housing 11 from the air inlet of the dust cup, it is filtered through the annular filter 21. The filtered airflow flows out of the dust cup assembly 2 or enters the next level of filtering structure to continue filtering. The specific filtering structure is not described in detail here. In order to effectively remove the dirt adhered to the periphery of the annular filter 21. A scraping mechanism 22 is provided on the periphery of the annular filter 21, and the scraping mechanism 22 is used to scrape at least part of the dirt on the surface of the annular filter 21. A driving device 3 is also provided on the main body 1. The driving device 3 includes a driver 31 and a transmission mechanism 32, and the driver 31 is arranged in the accommodating space. The driver 31 can be a motor, and a driving element that can generate a driving force such as a hydraulic drive can also be used, which is not described in detail here. One end of the transmission mechanism 32 is in transmission connection with the driver 31, and the other end of the transmission mechanism 32 acts on the scraping mechanism 22. The driver 31 is used to generate a driving force to move the scraping mechanism 22 along the axial direction of the annular filter screen 21 from the initial position of the scraping mechanism 22 (reference Figure 6 ) moves to the scraping end position (reference Figure 7 ). In this application, we will refer to the moving direction from the initial scraping position to the final scraping position as the scraping direction. The vacuum cleaner 101 includes a controller, through which the driving device 3 can be controlled to push the scraping mechanism 22. When the user finds that there is dirt adhering to the annular filter 21, the user can control the scraping mechanism 22 to automatically scrape the dust through the controller, and the user does not need to clean it manually. By arranging the driving device 3 in the main body 1 and controlling the operation of the driver 31, the scraping action of the scraping mechanism 22 is realized, and the dirt on the annular filter 21 is scraped off, avoiding the user from manually cleaning the annular filter 21.

[0035] refer to Figure 5-9The driver 31 adopts an electric motor, and the output shaft of the electric motor is connected to the transmission mechanism 32. In one embodiment, the transmission mechanism 32 includes a screw rod 33 that is transmission-connected to the driver 31 and a push rod 34 that is transmission-connected to the screw rod 33. One end of the push rod 34 is provided with a threaded structure that matches the screw rod 33. The screw rod 33 rotates to drive the push rod 34 to move in the scraping direction. The driving device 3 also includes at least one limit switch for controlling the stroke of the push rod 34. When the push rod 34 moves to a preset position, the limit switch is triggered. When the limit switch is triggered, the driver 31 stops working.

[0036] In another embodiment, the transmission mechanism 32 includes a push rod 34, and the push rod 34 is configured to abut against the scraping mechanism 22 to push the scraping mechanism 22 to move downward during the movement along the scraping direction. The push rod 34 can be connected to the output member of the driver 31 by other forms of transmission members. The transmission member can be a transmission structure such as a gear and a connecting rod. The scraping mechanism 22 includes an annular bracket 24 and a scraping bar 25 arranged on the annular bracket 24, and the scraping bar 25 is used to scrape at least part of the dirt attached to the surface of the annular filter 21. The push rod 34 can be configured to directly push the annular bracket 24 to move downward. The driving device 3 also includes at least one limit switch for controlling the stroke of the push rod 34. When the push rod 34 moves to a preset position, the limit switch is triggered. After the limit switch is triggered, the driver 31 stops working.

[0037] In other embodiments, the transmission structure may also adopt transmission forms such as gear transmission, connecting rod transmission or belt transmission.

[0038] In all the above embodiments, the driving device 3 can be installed in the main body 1 through the mounting plate 36. The mounting plate 36 can also be provided with a guide hole for guiding the movement of the push rod 34.

[0039] Based on any of the above embodiments, in order to ensure that the scraping mechanism 22 can move axially along the surface of the annular filter 21 without deviation as much as possible, the dust cup assembly 2 also includes a guide rod 23, which is installed on the dust cup assembly 2 and is used to guide the scraping mechanism 22 to move along the scraping direction.

[0040] refer to Figure 4 and 5In a specific embodiment, the scraping mechanism 22 includes an annular bracket 24 and a scraping strip 25 disposed on the annular bracket 24. The scraping strip 25 is used to scrape off at least part of the dirt attached to the surface of the annular filter 21. The scraping mechanism 22 also includes a connecting structure fixedly connected to the annular bracket 24. The connecting structure includes an extension rod 26 fixedly connected to the annular bracket 24 and a guide portion 27 fixedly connected to the extension rod 26; the guide portion 27 can reciprocate along the guide rod 23 installed on the dust cup assembly 2 to guide the annular bracket 24 to move along the guide rod 23 in the scraping direction. As shown in the embodiment shown in the figure, the push rod 34 can directly contact the position between the extension rod 26 and the guide portion 27 during the downward movement, which is conducive to the smooth movement of the scraping mechanism 22.

[0041] In order to facilitate the cleaning of the dust cup assembly 2, the transmission mechanism 32 and the scraping mechanism 22 are not fixedly connected. When the dust cup assembly 2 is separated from the main body 1, the scraping mechanism 22 can be separated from the driving device 3, especially from the transmission mechanism 32.

[0042] In order to enable the scraping mechanism 22 to return to the initial position smoothly, a rebound structure is provided at the guide rod 23, and the rebound structure is used to generate a driving force to move the scraping mechanism 22 from the scraping end position to the scraping initial position. In other embodiments, when the dust cup assembly 2 (scraping mechanism 22) is designed to be non-detachable, the push rod 34 can be fixedly connected to the transmission assembly, so that the rebound structure can be cancelled, and the reciprocating motion of the scraping mechanism 22 can be driven by the driver 31.

[0043] refer to Figure 8 In order to further ensure the stability of the operation of the scraping mechanism 22, the extension rod 26 is located on the inner side of the circumference defined by the side wall 35 of the dust cup, and the guide rod 23 is arranged on the outer side of the circumference defined by the side wall 35 of the dust cup.

[0044] refer to Figure 1 , the figure also discloses a cleaning system 100, which includes a vacuum cleaner 101 and a base station 102 docked with the vacuum cleaner 101. The base station 102 includes a dust storage space, which is used to store dirt transferred from the dust cup assembly 2. The base station 102 may include a fan for generating suction to transfer the dirt in the dust cup assembly 2 to the dust storage space. The base station 102 may not include a fan, and the dirt in the dust cup assembly 2 may be transferred to the dust storage space through the airflow generated by the suction motor 12 on the vacuum cleaner 101. The specific structure involved here will not be described in detail.

[0045] In a specific embodiment, the cleaning system 100 further includes a controller, which can be disposed in the base station 102 or in the vacuum cleaner 101. The controller is configured to control the driving device 3 to drive only after the vacuum cleaner 101 is docked to the base station 102. Specifically, when the controller receives or detects a charging signal, the controller is activated and can control the driving device 3. Alternatively, after the vacuum cleaner 101 is docked to the base station 102, the switch device is triggered, and after the switch device is activated, the controller can control the driving device 3.

[0046] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described here.
