DETAILED DESCRIPTION

[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0052] A mite remover is a cleaning device used to remove dust, mites and other allergens from textile items such as beds, sofas, carpets, and clothing. A mite remover usually includes a body and components such as a fan, a roller brush, and a dust cup installed inside the body. The suction port at the bottom of the cleaning device is in contact with the surface to be cleaned, and the roller brush is installed at the suction port. The suction force provided by the fan causes dust to be sucked from the suction port into the dust cup to achieve the dust removal function.

[0053] After using the self-cleaning device, you need to disassemble the dust cup, pour out the dust collected in the dust cup, and then install it. However, this method cannot clean the hair adhering to the filter screen, or the fine dust adhering to the dust cup wall and the narrow gap of the cup body. Although it can be cleaned by flushing, the fine floating dust with strong electrostatic adsorption is easy to adhere to the dust cup wall and the inside of the filter screen, and it is necessary to reach into the dust cup to clean it, which makes cleaning difficult.

[0054] Based on the above technical problems, an embodiment of the present invention is proposed, and the embodiment of the present invention may include a device body 1, a dust cup assembly 2, a first valve assembly 3, and a dust blower 4. A dust suction inlet 101 is provided on the device body 1, and the dust cup assembly 2 includes a cup body 21, a filter 22 located in the cup body 21, and a self-cleaning assembly 23 detachably connected to the cup body 21, wherein the cup body 21 is provided with a dust cup air inlet 2101 connected to the outside of the filter 22, and a dust cup air outlet 2102 connected to the inside of the filter 22, the dust cup air inlet 2101 is connected to the dust suction inlet 101 by air path, and the outside of the filter 22 is connected to the self-cleaning assembly 23 by air path. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the connection state of the dust cup air inlet 2101. The dust blower 4 is embedded in the device body 1 and is connected to the dust cup air outlet 2102 by air path. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 works to generate dust blowing airflow, driving the first valve assembly 3 to close the dust cup air inlet 2101, so as to blow the dust in the filter 22 into the self-cleaning assembly 23 through the dust blowing airflow. Through the pressure of the dust blowing fan 4, the fine dust attached to the filter screen of the filter 22, the back wall of the cup body 21, and the narrow slit of the cup body 21 are blown into the self-cleaning assembly 23. In this way, the self-cleaning assembly 23 can be disassembled to clean the fine dust attached to the surface, and there is no need to deeply clean different positions of the cup body 21, which reduces the difficulty of cleaning the dust cup.

[0055] Reference Figure 1-10The embodiment of the present invention provides a self-cleaning device, which may include a device body 1, a dust cup assembly 2, a first valve assembly 3 and a dust blower 4. The device body 1 is provided with a dust suction inlet 101. The dust cup assembly 2 includes a cup body 21, a filter 22 located in the cup body 21 and a self-cleaning assembly 23 detachably connected to the cup body 21, wherein the cup body 21 is provided with a dust cup air inlet 2101 connected to the outside of the filter 22, and a dust cup air outlet 2102 connected to the inside of the filter 22, the dust cup air inlet 2101 is connected to the dust suction inlet 101 in an air path, and the outside of the filter 22 is connected to the self-cleaning assembly 23 in an air path. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the connection state of the dust cup air inlet 2101. The dust blower 4 is embedded in the device body 1 and is connected to the dust cup air outlet 2102 in an air path. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 operates to generate dust blowing airflow, driving the first valve assembly 3 to close the dust cup air inlet 2101, so as to blow the dust in the filter 22 into the self-cleaning assembly 23 through the dust blowing airflow.

[0056] In the embodiment of the present invention, the device body 1 is used to provide the assembly of various components and the enclosure of the air duct involved in the embodiment of the present invention. A dust suction inlet 101 is provided on the device body 1. For example, the dust suction inlet 101 can be arranged at the bottom of the device body 1, so that it can form an abutment with the area to be dusted to adsorb dust and dirt. The dust cup assembly 2 is used to accommodate the dust and dirt adsorbed by the self-cleaning device during the dust suction process. The dust cup assembly 2 may include a cup body 21, a filter 22 and a self-cleaning assembly 23, wherein the cup body 21 can be connected to the device body 1, and the filter 22 is used to separate the dust and dirt adsorbed into the cup body 21 from air and dust. Air-dust separation can be understood as filtering the dust suction airflow, leaving the dust and dirt in the dust suction airflow in the cup body 21, and the filtered dust suction airflow can flow to the power source, thereby ensuring the service life of the power source.

[0057] The self-cleaning component 23 is detachably connected to the cup body 21 and communicated with the outside of the filter 22. The outside of the filter 22 is in air communication with the dust cup air inlet 2101 provided on the cup body 21. The dust cup air inlet 2101 is in air communication with the dust suction inlet 101, so that the adsorbed dust can enter the cup body 21 through the dust cup air inlet 2101, and is separated from the air and dust by the filter 22, and the filtered dust is accumulated in the cup body 21 and located on the outside of the filter 22. Thus, the fine dirt on the outside of the filter 22 and in the cup body 21 can be blown into the self-cleaning component 23 under the action of external force.

[0058] The first valve assembly 3 is located at the dust cup air inlet 2101 and is used to control the connection state of the dust cup air inlet 2101. For example, the airflow path of the self-cleaning device in different operating modes can be changed by controlling the closing and opening of the dust cup air inlet 2101.

[0059] The dust blowing fan 4 is embedded in the device body 1 and is connected to the dust cup air outlet 2102. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 generates dust blowing airflow and flows to the dust cup air outlet 2102, and then flows from the dust cup air outlet 2102 to the inside of the filter 22, and flows from the inside of the filter 22 to the outside of the filter 22, and blows up the fine dust adhering to the filter screen of the filter 22 and the fine dust accumulated in the cup body 21. The first valve assembly 3 is actuated by the driving force of the dust blowing airflow and closes the dust cup air inlet 2101. The dust blowing airflow with fine dust flows to the self-cleaning assembly 23 connected to the outside of the filter 22, and the fine dust is accumulated through the self-cleaning assembly 23. Therefore, the self-cleaning component 23 can be disassembled to clean the fine dust adhering to the surface, and there is no need to perform in-depth cleaning of different positions of the cup body 21, thereby reducing the difficulty of cleaning the dust cup.

[0060] The embodiment of the present invention also provides another self-cleaning device, which may include a device body 1, a dust cup assembly 2, a first valve assembly 3, a dust suction motor 5, a dust blowing motor and a second valve 61 assembly 6, wherein a dust suction inlet 101 is provided on the device body 1. The dust cup assembly 2 includes a cup body 21, a filter 22 located in the cup body 21 and a self-cleaning assembly 23 detachably connected to the cup body 21, wherein the cup body 21 is provided with a dust cup air inlet 2101 connected to the outside of the filter 22, and a dust cup air outlet 2102 connected to the inside of the filter 22, the dust cup air inlet 2101 is connected to the dust suction inlet 101 in an air path, and the outside of the filter 22 is connected to the self-cleaning assembly 23 in an air path. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the connection state of the dust cup air inlet 2101. The dust suction motor 5 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. The dust blowing fan 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. The second valve 61 assembly 6 is located at the air communication point between the dust suction motor 5 and the dust blowing fan 4.

[0061] In the embodiment of the present invention, the device body 1 is used to provide the assembly of various components and the enclosure of the air duct involved in the embodiment of the present invention. A dust suction inlet 101 is provided on the device body 1. For example, the dust suction inlet 101 can be arranged at the bottom of the device body 1, so that it can form an abutment with the area to be dusted to adsorb dust and dirt. The dust cup assembly 2 is used to accommodate the dust and dirt adsorbed by the self-cleaning device during the dust suction process. The dust cup assembly 2 may include a cup body 21, a filter 22 and a self-cleaning assembly 23, wherein the cup body 21 can be connected to the device body 1, and the filter 22 is used to separate the dust and dirt adsorbed into the cup body 21 from air and dust. Air-dust separation can be understood as filtering the dust suction airflow, leaving the dust and dirt in the dust suction airflow in the cup body 21, and the filtered dust suction airflow can flow to the power source, thereby ensuring the service life of the power source.

[0062] The self-cleaning component 23 is detachably connected to the cup body 21 and communicated with the outside of the filter 22. The outside of the filter 22 is in air communication with the dust cup air inlet 2101 provided on the cup body 21. The dust cup air inlet 2101 is in air communication with the dust suction inlet 101, so that the adsorbed dust can enter the cup body 21 through the dust cup air inlet 2101, and is separated from the air and dust by the filter 22, and the filtered dust is accumulated in the cup body 21 and located on the outside of the filter 22. Thus, the fine dirt on the outside of the filter 22 and in the cup body 21 can be blown into the self-cleaning component 23 under the action of external force.

[0063] The first valve assembly 3 is located at the dust cup air inlet 2101 and is used to control the connection state of the dust cup air inlet 2101. For example, the airflow path of the self-cleaning device in different operating modes can be changed by controlling the closing and opening of the dust cup air inlet 2101.

[0064] The dust suction motor 5 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. The dust suction motor 5 serves as a power source when the self-cleaning device is in the dust suction mode, and generates a dust suction airflow. The dust suction airflow can be driven by the pressure of the dust suction airflow to adsorb the dust and dirt at the dust suction inlet 101 to the dust cup air inlet 2101, and enter the cup body 21 through the dust cup air inlet 2101, and then enter the inner side of the filter 22 from the outer side of the filter 22, and flow from the inner side of the filter 22 through the dust cup air outlet 2102, and flow into the dust suction motor 5 through the dust cup air outlet 2102, and flow to the external environment through the dust suction motor 5.

[0065] The dust blowing fan 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. Thus, the dust blowing air duct between the dust cup air outlet 2102 and the dust blowing fan 4 and the dust suction air duct between the dust blowing fan 4 and the dust cup air outlet 2102 can form a part of common use. For example, a connecting air duct extends from the dust cup air outlet 2102, and the connecting air duct is in air communication with the air outlet duct of the dust blowing fan 4 and the air inlet duct of the dust suction motor 5, respectively. And the air outlet duct of the dust blowing fan 4 and the air inlet duct of the dust suction motor 5 are arranged at an angle.

[0066] The second valve 61 assembly 6 is located at the gas path connection between the dust suction motor 5 and the dust blowing fan 4. Thus, the dust cup air outlet 2102 can be controlled to communicate with the dust suction motor 5 or the dust blowing fan 4 through the second valve 61 assembly 6. For example, when the second valve 61 assembly 6 closes the air outlet duct of the dust blowing fan 4, the dust cup air outlet 2102 is in gas path communication with the dust suction motor 5. When the second valve 61 assembly 6 closes the air inlet duct of the dust suction motor 5, the dust cup air outlet 2102 is in gas path communication with the dust blowing fan 4.

[0067] When the self-cleaning device is in the dust suction mode, the dust suction motor 5 works to generate dust suction airflow, the first valve assembly 3 is in an open state, and the second valve 61 assembly 6 controls the air path between the dust cup air outlet 2102 and the dust blowing fan 4 to be closed. Thus, driven by the pressure of the dust suction airflow, the dust at the dust suction inlet 101 can be adsorbed to the dust cup air inlet 2101, and enter the cup body 21 through the dust cup air inlet 2101, and then enter the inner side of the filter 22 from the outer side of the filter 22, and flow from the inner side of the filter 22 through the dust cup air outlet 2102, flow into the dust suction motor 5 through the dust cup air outlet 2102, and flow to the external environment through the dust suction motor 5.

[0068] When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 works to generate dust blowing airflow, and the second valve 61 assembly 6 operates under the driving force of the dust blowing airflow, and controls the air path between the dust cup air outlet 2102 and the dust suction motor 5 to be closed. As a result, the dust blowing airflow flows from the dust cup air outlet 2102 to the inside of the filter 22, and flows from the inside of the filter 22 to the outside of the filter 22, and blows up the fine dust adhering to the filter screen of the filter 22 and the fine dust accumulated in the cup body 21. The first valve assembly 3 operates under the driving force of the dust blowing airflow, and closes the dust cup air inlet 2101. The dust blowing airflow with fine dust flows to the self-cleaning assembly 23 connected to the outside of the filter 22, and the fine dust is accumulated through the self-cleaning assembly 23. Therefore, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhered to the surface, and there is no need to perform in-depth cleaning of different positions of the cup body 21, which reduces the difficulty of cleaning the dust cup.

[0069] An optional embodiment of the invention, referring to Figure 3 and Figure 4 As shown, the second valve 61 assembly 6 includes a second valve 61 and a second torsion spring 62, and the second valve 61 is rotatably connected to the device body 1. One end of the second torsion spring 62 is fixed to the second valve 61, and the other end is in contact with the device body 1. When the dust blowing fan 4 is stationary, the second torsion spring 62 is in an initial state and closes the air outlet of the dust blowing fan 4. When the dust blowing fan 4 is working, the second torsion spring 62 is deformed under the action of the dust blowing airflow, driving the second valve 61 to rotate and close the air inlet of the dust suction motor 5.

[0070] In the embodiment of the present invention, the second valve 61 can be rotatably connected to the device body 1. For example, it can be rotatably connected to the connection between the air outlet duct of the dust blower 4 and the air inlet duct of the dust suction motor 5. In addition, one end of the second torsion spring 62 is fixedly connected to the second valve 61, and the other end of the second torsion spring 62 abuts against the device body 1, for example, the other end of the second torsion spring 62 abuts against the connection between the air outlet duct of the dust blower 4 and the air inlet duct of the dust suction motor 5. Therefore, the rotation of the second valve 61 can be controlled by the deformation state of the second torsion spring 62.

[0071] When the second torsion spring 62 is in the initial state (the torsion spring is not deformed), the second valve 61 closes the air outlet of the dust blower 4. Therefore, the dust cup air outlet 2102 is only connected to the air path of the dust suction motor 5, so that when the self-cleaning device is in the dust suction mode, the dust suction airflow will not flow to the air outlet of the dust blower 4.

[0072] When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 works and generates dust blowing airflow, thereby driving the second valve 61 to rotate in the direction away from the dust blowing fan 4 and approaching the air inlet of the dust suction motor 5. Under the action of the stable wind pressure of the dust blowing fan 4, the torsion spring is deformed, and the second valve 61 closes the air inlet of the dust suction motor 5. As a result, the dust cup air outlet 2102 is only connected to the air path of the dust blowing fan 4, thereby ensuring that the dust blowing airflow will not flow to the air inlet of the dust blowing fan 4 when the self-cleaning device is in the self-cleaning mode.

[0073] In some embodiments, the second valve 61 may be provided with an assembly hole near the second torsion spring 62, and one end of the second torsion spring 62 may be embedded in the assembly hole and abutted against the second valve 61. The other end of the second torsion spring 62 may be hinged to the device body 1. After the self-cleaning device stops the self-cleaning mode, the dust blower 4 stops working. The second torsion spring 62 recovers its deformation, so that the second valve 61, under the driving action of the second torsion spring 62, performs a rotational movement close to the dust blower 4 and closes the air outlet of the dust blower 4.

[0074] An optional embodiment of the invention, referring to Figure 5 and Figure 6 As shown, the cup body 21 may include a separation chamber 2103 and a dust collecting chamber 2104 connected to the separation chamber 2103, the filter 22 is located in the separation chamber 2103, and the self-cleaning component 23 is located in the dust collecting chamber 2104, wherein the outer side of the filter 22 is connected to the self-cleaning component 23 through an air path.

[0075] In an embodiment of the present invention, the cup body 21 may include a separation chamber 2103 and a dust collecting chamber 2104 connected to the separation chamber 2103. The separation chamber 2103 and the dust collecting chamber 2104 may be arranged side by side. The separation chamber 2103 is used to store dust and install the filter 22, and the filter 22 is located in the separation chamber 2103. The dust cup air outlet 2102 and the dust cup air inlet 2101 are respectively connected to the air path of the separation chamber 2103. Thus, during the dust cleaning process, the dust enters the separation chamber 2103 through the dust cup air inlet 2101, that is, it is located on the outside of the filter 22. Then it enters the inner side of the filter 22, and flows through the dust cup air outlet 2102 from the inner side of the filter 22, flows into the dust suction motor 5 through the dust cup air outlet 2102, and flows to the external environment through the dust suction motor 5.

[0076] The self-cleaning component 23 is located in the dust collecting chamber 2104 and is connected to the outside of the filter 22 through an air path. Thus, the size of dust entering the dust collecting chamber 2104 can be controlled through the communication gap between the dust collecting chamber 2104 and the separation chamber 2103. For example, the self-cleaning component 23 is mainly used to adhere to fine dust, so that the communication gap between the dust collecting chamber 2104 and the separation chamber 2103 can be made smaller, thereby preventing dirt with a larger area or larger particle size from entering the dust collecting chamber 2104.

[0077] An optional embodiment of the invention, referring to Figure 6 , Fig. 9 as well as Fig.10 As shown, the self-cleaning assembly 23 may include a self-cleaning box 231, a partition 232, a filter 233 and a self-cleaning valve 234. The self-cleaning box 231 is detachably connected to the cup body 21, wherein a self-cleaning chamber 23101 is provided in the self-cleaning box 231, and the self-cleaning chamber 23101 is in air communication with the dust collecting chamber 2104 and is also in air communication with the external environment. The partition 232 is located in the self-cleaning chamber 23101, and the filter 233 is arranged on the partition 232 to collect dust and dirt blown out from the separation chamber 2103. The self-cleaning valve 234 is located on the end surface of the partition 232 away from the filter 233, wherein the self-cleaning valve 234 closes the dust collecting chamber 2104 when the dust suction motor 5 is working, and the self-cleaning valve 234 is driven to open by the dust blowing airflow when the dust blowing fan 4 is working, so as to guide the dust blowing airflow out of the external environment.

[0078] In the embodiment of the present invention, the self-cleaning assembly 23 may include a self-cleaning box 231, a partition 232, a filter 233 and a self-cleaning valve 234. The self-cleaning box 231 is detachably connected to the cup body 21. Specifically, the self-cleaning box 231 may be detachably connected to the cavity wall of the dust collecting chamber 2104. The detachable connection may include one of the following ways: the self-cleaning box 231 is threadedly matched with the cup body 21; an elastic fastener is sleeved between the self-cleaning box 231 and the cup body 21, so that the self-cleaning box 231 and the cup body 21 form an interference fit through the elastic fastener; the self-cleaning box 231 and the cup body 21 are snap-fitted, etc.

[0079] A self-cleaning chamber 23101 is provided in the self-cleaning box 231, wherein the self-cleaning chamber 23101 has two openings, one opening of the self-cleaning chamber 23101 is in air communication with the dust collecting chamber 2104, and the other opening of the self-cleaning chamber 23101 is in air communication with the external environment. The partition 232 is located in the self-cleaning chamber 23101. The partition 232 may be a mesh structure, which is horizontally arranged in the self-cleaning chamber 23101. The partition 232 is used for the installation of the filter 233 and the self-cleaning valve 234 and other devices on the basis of ensuring the air communication of the self-cleaning chamber 23101. For example, the partition 232 may be an integrated structure with the self-cleaning box 231. The filter 233 is arranged on the partition 232, for example, a protrusion may be arranged at the center of the partition 232, and the filter 233 may be sleeved on the protrusion. This makes it easier to disassemble, assemble and clean the filter sheet 233 .

[0080] In some embodiments, the self-cleaning box 231 is close to the end surface of the dust collecting chamber 2104 and is flush with the bottom wall of the dust collecting chamber 2104, thereby preventing fine dust from accumulating in the gap at the connection between the dust collecting chamber 2104 and the self-cleaning box 231.

[0081] When the dust-blowing airflow with fine dust enters the dust collecting chamber 2104, it will first flow to the filter 233, and then flow through the partition 232 and the self-cleaning valve 234 after being filtered by the filter 233, and finally be guided out of the external environment. As a result, the fine dust will accumulate on the end surface of the filter 233 close to the dust collecting chamber 2104. After the self-cleaning mode ends, the self-cleaning box 231 can be disassembled and the filter 233 can be cleaned.

[0082] The self-cleaning valve 234 can be located on the end surface of the partition 232 away from the filter 233, and is used to control the on-off of the air path between the dust collecting chamber 2104 and the self-cleaning chamber 23101. When the self-cleaning device is in the dust suction mode, the self-cleaning valve 234 forms a closure on the self-cleaning chamber 23101. This ensures that when the self-cleaning device is in the dust suction mode, the dust suction airflow will not flow into the external environment through the dust collecting chamber 2104. When the self-cleaning device is in the self-cleaning mode, the self-cleaning valve 234 is in a conducting state, so that the self-cleaning chamber 23101 and the dust collecting chamber 2104 are connected by air. Therefore, when the self-cleaning device is in the self-cleaning mode, the dust blowing airflow can flow into the external environment through the dust collecting chamber 2104.

[0083] In some optional embodiments, the filter sheet 233 may be a high efficiency particulate air filter 22 (HEPA, Hing Efficiency Particulate Air).

[0084] An optional embodiment of the invention, the self-cleaning valve 234 includes two valve bodies and a self-cleaning torsion spring, wherein the two valve bodies are rotatably connected to the partition 232, and the two ends of the self-cleaning torsion spring are respectively connected to the two valve bodies. In addition, when the self-cleaning device is in the dust suction mode, the self-cleaning torsion spring is in the initial state, and the two valve bodies cooperate to form a closure on the dust collecting chamber 2104. When the self-cleaning device is in the self-cleaning mode, the self-cleaning torsion spring is deformed by the pressure of the dust blowing airflow, driving the valve body to rotate away from the dust collecting chamber 2104, so that the dust blowing airflow is introduced into the external environment through the valve body.

[0085] In the embodiment of the present invention, the self-cleaning valve 234 may include two valve bodies and a self-cleaning torsion spring, wherein when the two valve bodies are placed flush, the cross-sectional shape of the two valve bodies may be circular. Correspondingly, the self-cleaning box 231 may also be a circular tubular structure, and the filter 233, the partition 232 and the self-cleaning valve 234 may be coaxially arranged in the self-cleaning box 231.

[0086] The two valve bodies are rotatably connected to the partition 232, and are fixedly connected to the valve bodies through the two ends of the self-cleaning torsion spring. Therefore, when the self-cleaning torsion spring is in the initial state, the valve bodies are in a flush state under the action of the self-cleaning torsion spring, and cooperate with each other to form a closure on the dust collecting chamber 2104. When the self-cleaning device is in the self-cleaning mode, the dust blowing airflow applies a thrust to the valve body away from the dust collecting chamber 2104. Under the pressure of the dust blowing airflow, the two valve bodies rotate away from the dust collecting chamber 2104, thereby realizing the air path connection between the dust collecting chamber 2104 and the self-cleaning chamber 23101, and the dust blowing airflow flows into the external environment through the dust collecting chamber 2104. At this time, the self-cleaning torsion spring is deformed. When the self-cleaning mode stops, the thrust on the valve body is canceled, and the self-cleaning torsion spring recovers its deformation, thereby driving the two valve bodies to rotate close to the dust collecting chamber 2104 and close the dust collecting chamber 2104 again.

[0087] In the embodiment of the present invention, the first valve, the second valve 61 and the valve body can all be made of rubber valves, which have certain deformation properties, so as to better achieve the air path connection and air tightness in the embodiment of the present invention.

[0088] An optional embodiment of the invention, referring to Fig. 9 and Fig.10 As shown, the self-cleaning component 23 may also include a self-cleaning cover 235 and a gripping portion 236, wherein the self-cleaning cover 235 is fixed on the end surface of the self-cleaning box 231 away from the dust collecting chamber 2104, wherein the gripping portion 236 is located on the end of the cleaning cover away from the dust collecting chamber 2104.

[0089] In an embodiment of the present invention, the self-cleaning component 23 may include a self-cleaning cover 235 and a gripping portion 236. The self-cleaning cover 235 is located on the end face of the self-cleaning box 231 away from the dust collecting chamber 2104, that is, on the end face close to the external environment. This can prevent dirt from the external environment from entering the self-cleaning chamber 23101. The gripping portion 236 is located on the end of the cleaning cover away from the dust collecting chamber 2104, that is, on the end face close to the external environment. As a result, when the user disassembles and assembles the self-cleaning box 231, it is more convenient to apply a screwing force, or a push-pull force, through the gripping portion 236. The convenience of disassembly and assembly of the self-cleaning box 231 is improved.

[0090] When cleaning the self-cleaning component 23, the self-cleaning box 231 can be disassembled, and the filter 233 can be removed for cleaning, and the cleaned filter 233 or the replaced filter 233 can be installed on the partition 232, and finally the self-cleaning box 231 can be installed in the dust collecting chamber 2104.

[0091] An optional embodiment of the invention, referring to Figure 7 and Figure 8 As shown, the first valve assembly 3 may include a first valve and a first torsion spring, wherein the first valve is rotatably connected to the cup body 21 and is located at the dust cup air inlet 2101. One end of the first torsion spring is fixed to the first valve, and the other end is in contact with the cup body 21. The first torsion spring maintains an initial state in the absence of external force. That is, it can be understood that when the dust blowing fan 4 and the dust suction motor 5 are both in a stationary state, the first torsion spring is in an initial state, that is, no twisting occurs, and the dust cup air inlet 2101 is kept closed.

[0092] When the dust suction motor 5 is working, the first torsion spring is deformed under the influence of the dust suction airflow, and drives the first valve to rotate and open the dust cup air inlet 2101, so that the dust suction airflow enters the dust cup assembly 2 from the dust cup air inlet 2101. When the dust blowing fan 4 is working, the first valve is pressed against the dust cup air inlet 2101 under the influence of the dust blowing airflow, and at this time, the first torsion spring can generate less deformation force and keep the dust cup air inlet 2101 in a closed state under the influence of the dust blowing airflow.

[0093] An optional embodiment of the invention, referring to Figure 5 and Figure 6 As shown, the dust cup assembly 2 also includes a cup cover 24 , which is detachably connected to the cup body 21 and is located close to the outer side of the filter 22 .

[0094] In an embodiment of the present invention, the dust cup assembly 2 may further include a cup cover 24, and the cup cover 24 is detachably connected to the cup body 21. The detachable connection may include, but is not limited to, a snap connection, a threaded connection, and an interference fit. The cup cover 24 is located in the outer direction close to the filter 22. That is, the dust accumulated by the dust suction mode is located in the space formed by the outer side of the filter 22 and the cup body 21. When the dust is full, the cup cover 24 can be removed to pour out or take out the dust in the cup body 21. The fine dust adhered to the filter screen of the filter 22 and the fine dust accumulated in the cup body 21 are blown to the self-cleaning assembly 23 connected to the outer side of the filter 22 by running the dust blowing mode, and the fine dust is accumulated by the self-cleaning assembly 23. As a result, the self-cleaning assembly 23 can be disassembled to clean the fine dust adhered to the surface, and there is no need to perform in-depth cleaning of different positions of the cup body 21, which reduces the difficulty of cleaning the dust cup.

[0095] In summary, the embodiment of the present invention discloses a self-cleaning device, wherein when the self-cleaning device is in the dust suction mode, the dust suction motor 5 operates to generate dust suction airflow, and the dust located at the dust suction inlet 101 is sucked into the filter 22 for air-dust separation, and the dust suction airflow after separation flows into the dust suction motor 5 from the dust cup air outlet 2102. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 operates to generate dust blowing airflow, drives the second valve 61 component 6 to open and close the air inlet of the dust suction motor 5, drives the first valve component 3 to close the dust cup air inlet 2101, and the dust blowing airflow flows through the filter 22, and blows the dust in the filter 22 into the self-cleaning component 23. Through the pressure of the dust blowing fan 4, the fine dust attached to the filter screen of the filter 22, the back wall of the cup body 21, and the narrow slit of the cup body 21 are blown into the self-cleaning component 23. Therefore, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhered to the surface, and there is no need to perform in-depth cleaning of different positions of the cup body 21, which reduces the difficulty of cleaning the dust cup.

When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 operates to generate dust blowing airflow, drives the second valve 61 component 6 to open and close the air inlet of the dust suction motor 5, drives the first valve component 3 to close the dust cup air inlet 2101, and the dust blowing airflow flows through the filter 22, and blows the dust in the filter 22 into the self-cleaning component 23. Through the pressure of the dust blowing fan 4, the fine dust attached to the filter screen of the filter 22, the back wall of the cup body 21, and the narrow slit of the cup body 21 are blown into the self-cleaning component 23. Therefore, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhered to the surface, and there is no need to perform in-depth cleaning of different positions of the cup body 21, which reduces the difficulty of cleaning the dust cup.
