DETAILED DESCRIPTION

[0051] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although 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 described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] A mite remover is a cleaning device used to remove dust, mites, and other allergens from textiles like beds, sofas, carpets, and clothing. It typically consists of a main unit, along with a fan, roller brush, and dust cup. The suction port at the bottom of the cleaning unit contacts the surface being cleaned, while the roller brush is located at the inlet. The fan provides suction, drawing dust from the inlet into the dust cup, completing the dust removal process.

[0053] After using the self-cleaning device, you need to remove the dust cup, empty the collected dust, and then reinstall it. However, this method cannot clean hair stuck to the filter screen or fine dust stuck to the dust cup walls or narrow crevices. While flushing can be used to clean, fine dust particles with strong electrostatic attraction tend to adhere to the dust cup walls and filter screen, requiring you to reach into the dust cup to clean them, making cleaning difficult.

[0054] Based on the above technical problems, an embodiment of the present invention is proposed. 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. 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. 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 in air communication with the dust suction inlet 101, and the outside of the filter 22 is in air communication with the self-cleaning assembly 23. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the communication state of the dust cup air inlet 2101. The dust blower 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. When the self-cleaning device is in self-cleaning mode, the dust blower 4 operates to generate a dust-blowing airflow, driving the first valve assembly 3 to close the dust cup air inlet 2101. This dust-blowing airflow blows dust and dirt from the filter 22 into the self-cleaning assembly 23. The pressure from the dust blower 4 blows fine dust and dirt adhering to the filter screen of the filter 22, the back wall of the cup 21, and the narrow slits of the cup 21 into the self-cleaning assembly 23. This allows the self-cleaning assembly 23 to be disassembled to clean fine dust and dirt adhering to its surface, eliminating the need for in-depth cleaning of different locations on the cup 21 and reducing the difficulty of cleaning the dust cup.

[0055] Reference Figure 1-10The 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. 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 in air communication with the dust suction inlet 101, and the outside of the filter 22 is in air communication with the self-cleaning assembly 23. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the communication state of the dust cup air inlet 2101. The dust blower 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 works to generate a 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 set 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 collection 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 and 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 assembly 23 is detachably connected to the cup body 21 and communicates 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, and the dust cup air inlet 2101 is in air communication with the dust suction inlet 101. Thus, adsorbed dust and dirt can enter the cup body 21 through the dust cup air inlet 2101, and then be separated from the air and dust by the filter 22. The filtered dust and dirt is accumulated in the cup body 21 and located on the outside of the filter 22. Thus, under the action of an external force, fine dirt on the outside of the filter 22 and in the cup body 21 can be blown into the self-cleaning assembly 23.

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

[0059] The dust-blowing fan 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. When the self-cleaning device is in self-cleaning mode, the dust-blowing fan 4 generates a dust-blowing airflow that flows toward the dust cup air outlet 2102, and then flows from the dust cup air outlet 2102 to the inner side of the filter 22, and flows from the inner side of the filter 22 to the outer side 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 carrying fine dust flows to the self-cleaning assembly 23 that is in communication with the outer side of the filter 22, and accumulates the fine dust through the self-cleaning assembly 23. Thus, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhering 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.

[0060] 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 assembly 6. 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. 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 in air communication with the dust suction inlet 101, and the outside of the filter 22 is in air communication with the self-cleaning assembly 23. The first valve assembly 3 is located at the dust cup air inlet 2101 to control the communication 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 blower 4 is embedded in the device body 1 and is in air communication with the dust cup air outlet 2102. The second valve assembly 6 is located at the air communication point between the dust suction motor 5 and the dust blower 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 set 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 collection 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 and 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 assembly 23 is detachably connected to the cup body 21 and communicates 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, and the dust cup air inlet 2101 is in air communication with the dust suction inlet 101. Thus, adsorbed dust and dirt can enter the cup body 21 through the dust cup air inlet 2101, and then be separated from the air and dust by the filter 22. The filtered dust and dirt is accumulated in the cup body 21 and located on the outside of the filter 22. Thus, under the action of an external force, fine dirt on the outside of the filter 22 and in the cup body 21 can be blown into the self-cleaning assembly 23.

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

[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, generating 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 outside 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 then flow to the external environment through the dust suction motor 5.

[0065] The dust blower 4 is embedded in the device body 1 and is in air communication with the dust cup outlet 2102. Thus, the dust blowing duct between the dust cup outlet 2102 and the dust blower 4 and the dust collection duct between the dust blower 4 and the dust cup outlet 2102 can partially share a common duct. For example, a connecting duct can extend from the dust cup outlet 2102, and the connecting duct can be in air communication with the outlet duct of the dust blower 4 and the inlet duct of the dust collection motor 5, respectively. Furthermore, the outlet duct of the dust blower 4 and the inlet duct of the dust collection motor 5 are arranged at an angle.

[0066] The second valve assembly 6 is located at the air path connecting the dust collection motor 5 and the dust blower 4. Thus, the second valve assembly 6 can be used to control the air path connection between the dust cup air outlet 2102 and the dust collection motor 5, or the dust blower 4. For example, when the second valve assembly 6 closes the air outlet duct of the dust blower 4, the dust cup air outlet 2102 is in air path connection with the dust collection motor 5. When the second valve assembly 6 closes the air inlet duct of the dust collection motor 5, the dust cup air outlet 2102 is in air path connection with the dust blower 4.

[0067] When the self-cleaning device is in the dust collection mode, the dust collection motor 5 operates to generate dust collection airflow, the first valve assembly 3 is in an open state, and the second valve 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 collection airflow, dust and dirt at the dust collection inlet 101 are adsorbed onto the dust cup air inlet 2101, enter the cup body 21 through the dust cup air inlet 2101, then enter the filter 22 from the outside to the inside, and then flow from the inside of the filter 22 through the dust cup air outlet 2102, into the dust collection motor 5 through the dust cup air outlet 2102, and finally flow to the external environment through the dust collection motor 5.

[0068] When the self-cleaning device is in self-cleaning mode, the dust-blowing fan 4 operates to generate a dust-blowing airflow. The second valve assembly 6 is actuated by 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 then flows from the inside of the filter 22 to the outside of the filter 22, blowing 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 carrying fine dust flows to the self-cleaning assembly 23 connected to the outside of the filter 22, and the fine dust is accumulated by the self-cleaning assembly 23. Thus, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhering 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 utility model, referring to Figure 3 and Figure 4 As shown, the second valve assembly 6 includes a second valve 61 and a second torsion spring 62. 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 abuts the device body 1. When the dust blower 4 is stationary, the second torsion spring 62 is in an initial state and closes the air outlet of the dust blower 4. When the dust blower 4 is operating, the second torsion spring 62 deforms 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 this embodiment of the utility model, 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. Furthermore, 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 the device body 1. For example, the other end of the second torsion spring 62 abuts the connection between the air outlet duct of the dust blower 4 and the air inlet duct of the dust suction motor 5. Thus, 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 its initial state (no deformation), the second valve 61 closes the air outlet of the dust blower 4. As a result, the dust cup air outlet 2102 is only connected to the air path of the dust suction motor 5, thereby ensuring that the dust suction airflow does not flow to the air outlet of the dust blower 4 when the self-cleaning device is in the dust suction mode.

[0072] When the self-cleaning device is in self-cleaning mode, the dust blower 4 operates and generates a dust-blowing airflow, thereby driving the second valve 61 to rotate away from the dust blower 4 and toward the air inlet of the dust suction motor 5. Under the action of the stable wind pressure of the dust blower 4, the torsion spring deforms, 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 in air communication with the dust blower 4, thereby ensuring that the dust-blowing airflow does not flow toward the air inlet of the dust blower 4 when the self-cleaning device is in self-cleaning mode.

[0073] In some embodiments, the second valve 61 may have an assembly hole near the second torsion spring 62, and one end of the second torsion spring 62 may be inserted into the assembly hole, abutting 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 operating. The second torsion spring 62 recovers its shape, allowing the second valve 61, driven by the second torsion spring 62, to rotate closer to the dust blower 4 and close the air outlet of the dust blower 4.

[0074] An optional embodiment of the utility model, referring to Figure 5 and Figure 6As 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 forms an air path connection with the self-cleaning component 23.

[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. 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 separation chamber 2103 by air. 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 from the inner side of the filter 22 through the dust cup air outlet 2102, 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 assembly 23 is located in the dust collection chamber 2104 and is in air communication with the outside of the filter 22. The size of dust entering the dust collection chamber 2104 can be controlled by adjusting the gap between the dust collection chamber 2104 and the separation chamber 2103. For example, the self-cleaning assembly 23 is primarily used to trap fine dust, thereby reducing the gap between the dust collection chamber 2104 and the separation chamber 2103 and preventing larger dust or larger particles from entering the dust collection chamber 2104.

[0077] An optional embodiment of the utility model, referring to Figure 6 、 Figure 9 as well as Figure 10As 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. A self-cleaning chamber 23101 is defined within the self-cleaning box 231. The self-cleaning chamber 23101 is in air communication with the dust collection chamber 2104 and the external environment. The partition 232 is located within the self-cleaning chamber 23101. The filter 233 is disposed on the partition 232 to collect dust blown out of the separation chamber 2103. The self-cleaning valve 234 is located on the end face of the partition 232 away from the filter 233. When the dust suction motor 5 is operating, the self-cleaning valve 234 closes the dust collection chamber 2104. When the dust blower 4 is operating, the self-cleaning valve 234 is driven open by the dust blowing airflow to direct the dust blowing airflow into 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 wall of the dust collecting chamber 2104. The detachable connection may include one of the following methods: the self-cleaning box 231 is threadedly engaged 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] The self-cleaning box 231 defines a self-cleaning chamber 23101, wherein the self-cleaning chamber 23101 has two openings: one opening of the self-cleaning chamber 23101 is in air communication with the dust collection 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 grid structure, which is horizontally arranged in the self-cleaning chamber 23101. In addition to ensuring air communication with the self-cleaning chamber 23101, the partition 232 is also used to install components such as the filter 233 and the self-cleaning valve 234. For example, the partition 232 may be an integral structure with the self-cleaning box 231. The filter 233 is disposed on the partition 232. For example, a protrusion may be provided in the center of the partition 232, and the filter 233 may be mounted on the protrusion. This makes it easier to disassemble, assemble, and clean the filter 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 carrying fine dust enters the dust collection chamber 2104, it first flows toward the filter 233. After being filtered by the filter 233, it flows through the partition 232 and the self-cleaning valve 234, and finally flows out to the external environment. As a result, fine dust accumulates on the end surface of the filter 233 near the dust collection chamber 2104. After the self-cleaning mode ends, the self-cleaning box 231 can be removed 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 seal 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 the on state, so that the self-cleaning chamber 23101 and the dust collecting chamber 2104 are connected by air. This allows the dust blowing airflow to flow into the external environment through the dust collecting chamber 2104 when the self-cleaning device is in the self-cleaning mode.

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

[0084] In an optional embodiment of the utility model, 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. Furthermore, when the self-cleaning device is in dust collection mode, the self-cleaning torsion spring is in an initial state, and the two valve bodies cooperate to form a seal on the dust collection chamber 2104. When the self-cleaning device is in 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 collection chamber 2104, so that the dust-blowing airflow is introduced into the external environment through the valve body.

[0085] In this embodiment of the present invention, the self-cleaning valve 234 may include two valve bodies and a self-cleaning torsion spring. When the two valve bodies are placed flush with each other, the cross-section of the two valve bodies may be circular. Accordingly, the self-cleaning box 231 may also be a circular tubular structure, and the filter 233, partition 232, and self-cleaning valve 234 may be coaxially arranged within 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 seal 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 achieving air communication between the dust collecting chamber 2104 and the self-cleaning chamber 23101. 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 utility model, referring to Figure 9 and Figure 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 face 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 utility model, 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 disassembling and assembling 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. 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 utility model, referring to Figure 7 and Figure 8 As shown, the first valve assembly 3 may include a first valve and a first torsion spring. 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 its initial state in the absence of external force. That is, it can be understood that when the dust blower 4 and the dust suction motor 5 are both in a stationary state, the first torsion spring is in its initial state, i.e., no twisting occurs, and the dust cup air inlet 2101 is kept closed.

[0092] When the dust suction motor 5 is in operation, the first torsion spring is deformed by the dust suction airflow, driving 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 through the dust cup air inlet 2101. When the dust blowing fan 4 is in operation, the first valve is pressed against the dust cup air inlet 2101 by the dust blowing airflow. At this time, the first torsion spring can generate less deformation force, and the dust cup air inlet 2101 is kept closed by the dust blowing airflow.

[0093] An optional embodiment of the utility model, referring to Figure 5 and Figure 6 As shown, the dust cup assembly 2 further includes a cup cover 24 , which is detachably connected to the cup body 21 and is located near 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, which is detachably connected to the cup body 21. The detachable connection may include, but is not limited to, a snap-on connection, a threaded connection, and an interference fit. The cup cover 24 is located near the outside of the filter 22. In other words, dust accumulated during the vacuuming mode is located in the space formed by the outside 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 remove the dust from the cup body 21. Fine dust adhering to the filter screen of the filter 22 and fine dust accumulated in the cup body 21 are blown into the self-cleaning assembly 23 connected to the outside of the filter 22 by operating 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 removed to clean fine dust adhering to the surface, eliminating the need for in-depth cleaning of different locations of the cup body 21, thereby reducing the difficulty of cleaning the dust cup.

[0095] In summary, the present invention discloses a self-cleaning device. When the self-cleaning device is in suction mode, the dust suction motor 5 operates to generate a dust suction airflow, drawing dust located at the dust suction inlet 101 into the filter 22 for air-dust separation. The separated dust suction airflow then flows from the dust cup air outlet 2102 into the dust suction motor 5. When the self-cleaning device is in suction mode, the dust blower 4 operates to generate a dust blowing airflow, driving the second valve 61 assembly 6 to open and close the air inlet of the dust suction motor 5, and driving the first valve assembly 3 to close the dust cup air inlet 2101. The dust blowing airflow flows through the filter 22, blowing dust in the filter 22 into the self-cleaning assembly 23. The pressure from the dust blower 4 blows fine dust adhering to the filter screen of the filter 22, the back wall of the cup 21, and the narrow slit of the cup 21 into the self-cleaning assembly 23. Thus, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhering 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.

[0096] The embodiment of the present utility model further discloses a mite removal device, which may include the self-cleaning device described in any one of the above-mentioned embodiments of the utility model.

[0097] In the embodiments of the present invention, the mite remover is a cleaning device used to remove dust, mites, and other allergens from textile items such as beds, sofas, carpets, and clothing. The mite remover incorporates the self-cleaning device described in any of the aforementioned embodiments, eliminating the need for in-depth cleaning of different locations within the dust cup, thus reducing the cleaning effort.

[0098] In summary, the present invention also discloses a mite removal device. When the self-cleaning device is in the dust collection mode, the dust collection motor 5 operates to generate a dust collection airflow, which draws dust and dirt located at the dust collection inlet 101 into the filter 22 for air-dust separation. The separated dust collection airflow flows from the dust cup air outlet 2102 into the dust collection motor 5. When the self-cleaning device is in the self-cleaning mode, the dust blowing fan 4 operates to generate a dust blowing airflow, driving the second valve 61 assembly 6 to open and close the air inlet of the dust collection motor 5, and driving the first valve assembly 3 to close the dust cup air inlet 2101. The dust blowing airflow flows through the filter 22, blowing dust and dirt in the filter 22 into the self-cleaning assembly 23. The pressure of the dust blowing fan 4 blows fine dust and dirt 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 into the self-cleaning assembly 23. Thus, the self-cleaning component 23 can be disassembled to clean the fine dust and dirt adhering 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.
