DETAILED DESCRIPTION

[0036] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0037] As shown in Figures 1 to 16 , the embodiment of the present application provides an air conditioning equipment 10, wherein the air conditioning equipment 10 can include but not limited to air purifier, air conditioner, humidifier and other equipment, and the present application takes the air purifier as an example for description.

[0038] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 , the air conditioning equipment 10 provided by the embodiment of the present application includes: a main body 100, a cleaning assembly 400, and a filter screen 140 and a power assembly arranged on the main body 100, the cleaning assembly 400 includes a comb piece 410, the power assembly is connected with the comb piece 410 to drive the comb piece 410 to move relative to the filter screen 140; the comb piece 410 is provided with a first comb part 4101 and a second comb part 4102, the first comb part 4101 is configured to clean the filter screen 140 by abutting against the filter screen 140 and moving relative to the filter screen 140, and the second comb part 4102 is directed to at least part of the power assembly to scrape off dirt near at least part of the power assembly.

[0039] As shown in Figure 1 and Figure 2As shown, the air conditioning device 10 can include a main body 100, a cleaning assembly 400, a filter screen 140 and a power assembly, the filter screen 140 and the power assembly are arranged on the main body 100, and the airflow flows through the filter screen 140, and the airflow flowing through the filter screen 140 can be filtered by the filter screen 140, so that the dirt carried in the airflow is filtered by the filter screen 140 and collected on the filter screen 140.

[0040] As shown, Figure 5 The cleaning assembly 400 provided by the embodiment includes a comb tooth piece 410, and the power assembly is connected with the comb tooth piece 410 to drive the comb tooth piece 410 to move relative to the filter screen 140. The comb tooth piece 410 is provided with a first comb tooth part 4101 and a second comb tooth part 4102. When the comb tooth piece 410 moves relative to the filter screen 140 with the power assembly, the first comb tooth part 4101 is abutted with the filter screen 140, so that the first comb tooth part 4101 can clean the filter screen 140 during the movement relative to the filter screen 140, and at least part of the dirt on the filter screen 140 is removed, thereby realizing the self-cleaning operation of the filter screen 140, so that the filter screen 140 has high cleanliness, which is beneficial to improve the ventilation of the filter screen 140 and reduce the phenomenon of filter screen 140 blockage caused by dust and particle dirt accumulation, thereby improving the purification efficiency of the air conditioning device 10. At the same time, compared with manual cleaning of the filter screen 140, this design simplifies the manual cleaning operation of the user, improves the cleaning experience of the filter screen 140, is beneficial to reduce the maintenance demand of the user to the equipment, and improves the use convenience and user experience.

[0041] By arranging the second comb tooth part 4102 towards at least part of the power assembly, when the comb tooth piece 410 moves relative to the filter screen 140 with the power assembly, the second comb tooth part 4102 can scrape off at least part of the dirt such as hair balls near the power assembly, thereby reducing the problem that the dirt such as hair balls affects the smoothness of the power connection between the power assembly and the comb tooth piece 410, such as reducing the phenomenon that the dirt such as hair balls causes the threaded transmission connection between the power assembly and the comb tooth piece 410 to be blocked or stuck. Therefore, by arranging the second comb tooth part 4102, the cleanliness near at least part of the power assembly can be improved, so that the power assembly and the comb tooth piece 410 can be smoothly and reliably power connected, so that the cleaning assembly 400 can move smoothly relative to the filter screen 140, and the problem that the performance may be reduced or the equipment may be malfunctioned due to the blockage of the connection position between the power assembly and the comb tooth piece 410 can be reduced, so that the equipment can still run smoothly after a long time of operation, the maintenance frequency is reduced, and a more reliable and low-maintenance use experience is provided for the user.

[0042] The second comb tooth part 4102 and the first comb tooth part 4101 are arranged in different directions, so that the second comb tooth part 4102 does not hinder the first comb tooth part 4101 from smoothly abutting against the filter screen 140, and the first comb tooth part 4101 does not hinder the second comb tooth part 4102 from smoothly scraping off dirt near the partial power assembly, so that the two can reliably work, and the cleanliness of the filter screen 140 and the cleanliness near the partial power assembly are improved.

[0043] That is, the cleaning assembly 400 provided by the embodiment of the present application is provided with the first comb tooth part 4101 and the second comb tooth part 4102 on the comb tooth piece 410, the first comb tooth part 4101 is configured to abut against the filter screen 140, and the second comb tooth part 4102 is arranged towards the at least partial power assembly. In this way, during movement of the power assembly relative to the filter screen 140, the first comb tooth part 4101 can perform a cleaning operation on the filter screen 140, and the second comb tooth part 4102 can scrape off dirt near the at least partial power assembly. Thus, by using the comb tooth piece 410, dual cleaning of the filter screen 140 and the environment near the partial power assembly is achieved, the functionality is diversified, the cleanliness of the filter screen 140 is improved, the equipment can still run smoothly after a long time of operation, the maintenance frequency is reduced, a more reliable and low-maintenance use experience is provided for the user, and the application is suitable for popularization and application.

[0044] In some embodiments, as shown in Figure 5 The first comb tooth part 4101 is provided with the first cleaning tooth 411 which can abut against the filter screen 140. The first cleaning tooth 411 is used to abut against the filter screen 140 to scrape off dirt on the filter screen 140. The scraping action of the first cleaning tooth 411 is conducive to improving the cleaning efficiency and cleaning effect of the cleaning assembly 400 on the filter screen 140, and further improving the cleanliness of the filter screen 140. Meanwhile, the arrangement of the first cleaning tooth 411 can reduce the possibility of the comb tooth piece 410 being entangled with hair. As the first cleaning teeth 411 are arranged in rows, the entanglement risk of long and thin dirt such as hair between the teeth during the cleaning process is reduced, the possibility of performance degradation or equipment failure caused by the entanglement of the first cleaning tooth 411 is reduced, the equipment can still maintain high filtering and cleaning effect after a long time of operation, and a more reliable and low-maintenance use experience is provided for the user.

[0045] It can be understood that in some examples, the comb tooth piece 410 can be made of a material that does not stick to hair, so that the comb tooth piece 410 itself is not easy to stick to hair, and the possibility of performance degradation or equipment failure caused by the entanglement of the first cleaning tooth 411 is further reduced.

[0046] Further, as shown in Figure 6As shown, the tooth tip of the first cleaning tooth 411 is provided with a first circular arc structure 412, that is, the first cleaning tooth 411 is a circular arc tooth structure. This design makes the outer edge of the entire first cleaning tooth 411 a relatively smooth curved surface structure, which can reduce the possibility of the outer edge of the first cleaning tooth 411 having a sharp corner structure and scratching the user, thereby improving the safety of use by the user. At the same time, the tooth tip of the first cleaning tooth 411 is provided with the first circular arc structure 412, so that the tooth tip of the first circular arc structure 412 can penetrate deeply into the inside of the hair mass and other accumulated dirt, effectively removing hair and other dirt, thereby improving the cleaning effect of the dirt and further improving the cleanliness of the filter screen 140. At the same time, this design makes the first cleaning tooth 411 contact the filter screen 140 through the first circular arc structure 412, that is, the outer edge of the first cleaning tooth 411 contacting the filter screen 140 can be a relatively smooth curved surface structure. Therefore, it can reduce the possibility of the outer edge of the first cleaning tooth 411 contacting the filter screen 140 having a sharp corner structure and scratching or wearing the filter screen 140, which is conducive to reducing the wear of the filter screen 140 by the first cleaning tooth 411 and improving the service life of the filter screen 140. Overall, this design improves the cleaning effect of the first cleaning tooth 411, plays a role in preventing scratching and wearing of the filter screen 140, improves the safety of use by the user, and is conducive to prolonging the service life of the filter screen 140.

[0047] In some embodiments, the diameter of the first circular arc structure 412 is as shown by D1 in Figure 8 The diameter D1 of the first circular arc structure 412 ranges from 1.5 mm to 2.5 mm. By reasonably setting the range of the diameter of the first circular arc structure 412, the tooth tip of the first cleaning tooth 411 can have a good anti-scratching effect, which reduces the possibility of the first cleaning tooth 411 scratching the user and wearing the filter screen 140, while enabling the first cleaning tooth 411 to have a good cleaning effect. Specifically, the diameter of the first circular arc structure 412 can range from 1.5 mm, 2 mm, 2.5 mm, or any size within the range of 1.5 mm to 2.5 mm.

[0048] The spacing between the two adjacent first cleaning teeth 411 is as shown by S1 in Figure 8 The spacing S1 between the two adjacent first cleaning teeth 411 can range from 6 mm to 8 mm, that is, the spacing between the first cleaning teeth 411 arranged in a row ranges from 6 mm to 8 mm. The tooth height of the first cleaning tooth 411 is as shown by H1 in Figure 8 The tooth height H1 of the first cleaning tooth 411 ranges from 1.8 mm to 2 mm. The side edge angle of the first cleaning tooth 411 is as shown by a in Figure 8The side edge included angle a of the first cleaning tooth 411 is in the range of 42° to 62°, as indicated by a in the figure. By reasonably setting the spacing S1 between the two adjacent first cleaning teeth 411, and / or, by reasonably setting the tooth height H1 of the first cleaning tooth 411, and / or, by reasonably setting the side edge included angle a of the first cleaning tooth 411, the tooth tip of the first cleaning tooth 411 can smoothly drill into the hair ball and other dirt, so that the hair ball and other dirt can be smoothly and effectively scraped off by the first cleaning tooth 411, so that the row of first cleaning teeth 411 has good effect of scraping off dirt, at the same time, the risk of the hair and other elongated dirt winding around the first cleaning tooth 411 during cleaning the filter screen 140 can be reduced, so that the device can still maintain high filtering and cleaning effect after long time running, the problem of performance degradation or device failure caused by the first cleaning tooth 411 being wound by dirt can be reduced, and a more reliable and low-maintenance use experience is provided for the user.

[0049] Specifically, the spacing S1 between the two adjacent first cleaning teeth 411 can be 6mm, 7mm, 8mm, or any size in the range of 6mm to 8mm. The tooth height H1 of the first cleaning tooth 411 can be 1.8mm, 1.9mm, 2mm, or any size in the range of 1.8mm to 2mm. The side edge included angle a of the first cleaning tooth 411 can be 42°, 47°, 52°, 57°, 62°, or any angle in the range of 42° to 62°.

[0050] As shown in FIG. 6, Figure 7 , Figure 8 and Figure 9 The first cleaning tooth 411 is arranged in a row on the comb piece 410, and the row of first cleaning teeth 411 includes first sub cleaning teeth 413 at both ends and second sub cleaning teeth 414 between the two first sub cleaning teeth 413, that is, among the plurality of first cleaning teeth 411 arranged in a row, the first sub cleaning teeth 413 are located at the two side ends, and the second sub cleaning teeth 414 are located in the middle. Among them, the diameter of the first circular arc structure 412 of the first sub cleaning tooth 413 is greater than the diameter of the first circular arc structure 412 of the second sub cleaning tooth 414, and / or the thickness of the first sub cleaning tooth 413 is greater than the thickness of the second sub cleaning tooth 414.

[0051] That is, in some examples, as Figure 7 and Figure 8As shown, by setting the diameter of the first arc structure 412 of the first sub-cleaning tooth 413 to be larger than the diameter of the first arc structure 412 of the second sub-cleaning tooth 414, the tooth tips of the two first sub-cleaning teeth 413 located at both ends are larger in the tooth width direction than the tooth tip of the second sub-cleaning tooth 414 located in the middle, thereby achieving the blunting treatment of the tooth tips of the first sub-cleaning teeth 413. The tooth width direction can be parallel to the direction of the distance between two adjacent first cleaning teeth 411. The tooth width direction can be as follows: Figure 8 As indicated by the arrow X in the diagram.

[0052] In some examples, such as Figure 5 and Figure 6 As shown, by setting the thickness of the first sub-cleaning tooth 413 to be greater than the thickness of the second sub-cleaning tooth 414, the tooth tips of the two first sub-cleaning teeth 413 located at both ends are larger in the tooth thickness direction than the tooth tip of the second sub-cleaning tooth 414 located in the middle, thereby achieving a blunting treatment of the tooth tips of the first sub-cleaning teeth 413. The tooth thickness direction can be perpendicular to the direction of the distance between two adjacent first cleaning teeth 411. The tooth height direction can be as follows... Figure 6 As shown by arrow Y in the diagram, the direction of the tooth width can be as follows: Figure 6 As indicated by the arrow X in the diagram.

[0053] In other examples, such as Figure 6 and Figure 8 As shown, by setting the diameter of the first arc structure 412 of the first sub-cleaning tooth 413 to be larger than the diameter of the first arc structure 412 of the second sub-cleaning tooth 414, and setting the thickness of the first sub-cleaning tooth 413 to be larger than the thickness of the second sub-cleaning tooth 414, the tooth tips of the two first sub-cleaning teeth 413 located at both ends are increased in the tooth width direction and the tooth thickness direction of the tooth tip of the second sub-cleaning tooth 414 located in the middle, so as to achieve the passivation treatment of the tooth tips of the first sub-cleaning tooth 413.

[0054] In the above embodiment, since the probability of the user touching the first sub-cleaning tooth 413 located at the end is greater than the probability of the user touching the second sub-cleaning tooth 414 located in the middle when the user holds or transports the cleaning component 400, by blunting the tip of the first sub-cleaning tooth 413, the possibility of the first sub-cleaning tooth 413 scratching the user can be greatly reduced, and the safety of the user can be further improved.

[0055] Furthermore, the first cleaning teeth 411 arranged in a row can be arranged parallel to the plane containing the filter screen 140, so that most or every one of the first cleaning teeth 411 can abut against the filter screen 140, increasing the coverage area of ​​the first cleaning teeth 411 on the filter screen 140, thereby improving the cleaning efficiency and effect of the first cleaning teeth 411.Figure 2 As shown, the first cleaning teeth 411 are arranged in a row along the width direction of the filter screen 140.

[0056] like Figure 5 and Figure 14 As shown, in some embodiments, the second comb portion 4102 is provided with second cleaning teeth 415, which are arranged along the thickness direction of the filter screen 140. The thickness direction of the filter screen 140 is perpendicular to the direction of the plane containing the filter screen 140, and can also be understood as the direction in which airflow passes through the filter screen 140. The thickness direction of the filter screen 140 can be as follows: Figure 2 As indicated by arrow Y. It can be understood that the comb tooth 410 can move up and down along the height direction of the filter screen 140, as shown by the power assembly. Figure 2 As indicated by arrow Z in the diagram. The first cleaning tooth 411 is arranged along the width direction of the filter screen 140, and the width direction of the filter screen 140 can be as follows: Figure 2 As indicated by the arrow X in the diagram.

[0057] In this embodiment, the scraping action of the second cleaning teeth 415 helps improve the cleaning efficiency and effect of the cleaning component 400 on the environment near some power components, further improving the smoothness of the power connection between the power component and the comb tooth 410. At the same time, the arrangement of the second cleaning teeth 415 can reduce the possibility of the comb tooth 410 itself being entangled in hair, enabling the device to continue operating smoothly after long-term operation and reducing the maintenance frequency. Furthermore, the second cleaning teeth 415 arranged along the thickness direction of the filter screen 140 can be arranged adjacent to the first cleaning teeth 411 arranged along the width direction of the filter screen 140, that is, the first comb tooth 4101 and the second comb tooth 4102 can be arranged adjacent to each other to meet the design requirements of the entire comb tooth 410 having a compact structure and small size.

[0058] The second cleaning teeth 415 are arranged perpendicular to the arrangement direction of the first cleaning teeth 411. For example, the first cleaning teeth 411 can be understood as being arranged in rows laterally along the width direction of the filter screen 140, while the second cleaning teeth 415 can be understood as being arranged in rows vertically along the thickness direction of the filter screen 140. This ensures that the second cleaning teeth 415 do not obstruct reliable contact between the first cleaning teeth 411 and the filter screen 140. Simultaneously, the second cleaning teeth 415 have a good scraping effect on lint and other dirt near some power components.

[0059] Furthermore, such as Figure 9 and Figure 10 As shown, the tooth height direction of the first cleaning tooth 411 can be aligned with... Figure 2The Z-direction is parallel, such as the tooth height direction of the first cleaning tooth 411 being parallel to the height direction of the filter screen 140. In this way, when the first cleaning tooth 411 contacts the filter screen 140, under the drive of the power component, the comb tooth 410 moves downward along the height direction of the filter screen 140, so that the dirt on the filter screen 140 can be scraped off by the first cleaning tooth 411. At the same time, the second cleaning tooth 415 scrapes off some of the dirt near the power component.

[0060] Furthermore, Figure 9 and Figure 10 As shown, the tooth height direction of the second cleaning tooth 415 is parallel to... Figure 2 The X direction is parallel, such as the tooth height direction of the second cleaning tooth 415 being parallel to the width direction of the filter screen 140. It can also be understood that the tooth height direction of the second cleaning tooth 415 is perpendicular to the movement direction of the comb 410 relative to the filter screen 140. In this way, during the process of the comb 410 moving up and down relative to the filter screen 140 along the height direction of the filter screen 140, the second cleaning tooth 415 can smoothly scrape away some of the dirt near the power components.

[0061] In some embodiments, such as Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, the cleaning assembly 400 further includes: a fixing frame 420, a comb tooth 410 connected to the fixing frame 420, and a power assembly configured to be poweredly connected to the fixing frame to drive the comb tooth 410 to move relative to the filter screen 140. Thus, during the relative movement of the comb tooth 410 and the filter screen 140, the first cleaning teeth 411 on the comb tooth 410 interfere with the filter screen 140, scraping away dirt from the filter screen 140 and achieving the cleaning effect on the filter screen 140.

[0062] Furthermore, such as Figure 2 As shown, the power assembly drives the comb teeth 410 to move vertically relative to the filter screen 140 via the fixed frame 420. The vertical direction is as follows: Figure 2 As shown by arrow Z, the first cleaning teeth 411 are arranged in a row along the horizontal direction, and the horizontal direction can be as follows: Figure 2 As indicated by arrow X in the diagram. Thus, during the vertical relative movement of the comb teeth 410 and the filter screen 140, the horizontally arranged rows of first cleaning teeth 411 contact the filter screen 140, providing a large contact area that comprehensively covers the entire surface area of ​​the filter screen 140. This effectively removes dirt from the filter screen 140, improving cleaning efficiency and effectiveness. It is understood that in some examples, the power assembly drives the comb teeth 410 to move relative to the filter screen 140 horizontally or in other directions via the mounting bracket 420, and the first cleaning teeth 411 can be arranged in rows vertically or in other directions.

[0063] It can be understood that, Figure 2 The arrow Z in the filter screen 140 can also represent the height direction, Figure 3 The arrow X in the filter screen 140 can also represent the width direction, Figure 2 The arrow Y in the filter screen 140 can also represent the thickness direction, and the cleaning principle is the same as described above, which will not be repeated here.

[0064] In some embodiments, as shown in Figure 5 、 Figure 7 、 Figure 9 、 Figure 10 Two comb teeth 410 are connected on both sides of the fixed frame 420, that is, the fixed frame 420 is located between the two comb teeth 410, so that the fixed frame 420 located in the middle is power connected with the power assembly, that is, the two comb teeth 410 can be driven to move relative to the filter screen 140. That is, by power connecting the power assembly with the fixed frame 420 located in the middle, the entire cleaning assembly 400 can be driven to move relative to the filter screen 140. Compared with two power assemblies connected with the cleaning assembly 400 from both sides to drive the entire cleaning assembly 400 to move relative to the filter screen 140, the number of power assemblies is simplified, which is conducive to saving cost and meeting the design requirements of compact structure and small size of the air conditioning equipment 10, and is suitable for popularization and application.

[0065] In the above embodiment, as shown in Figure 2 、 Figure 5 、 Figure 6 and Figure 10 The power assembly includes a transmission assembly 300, the transmission assembly 300 is in transmission connection with the cleaning assembly 400, and the transmission assembly 300 includes a dustproof piece 310, and the second comb tooth part 4102 is arranged towards the dustproof piece 310.

[0066] The transmission assembly 300 is in transmission connection with the cleaning assembly 400, so that the movement of the transmission assembly 300 can drive the cleaning assembly 400 to move. Specifically, the transmission assembly 300 can further include a transmission rod 320, and the transmission rod 320 is connected with the cleaning assembly 400, such as the transmission rod 320 being connected with the fixed frame 420 of the cleaning assembly 400. Thus, the power assembly drives the fixed frame 420 to move through the transmission rod 320, which can drive the two comb teeth 410 to move relative to the filter screen 140, and the structure is simple and the volume is small.

[0067] The dust cover 370 of the transmission assembly 300 can at least partially shield the periphery of the transmission rod 320, thereby reducing the possibility of dirt such as hair being clamped in the matching structure of the transmission rod 320 and the fixing frame 420, reducing the possibility of the transmission assembly 300 and the cleaning assembly 400 being not smoothly connected, and dirt such as hair being difficult to clean, thereby improving the smoothness of the movement of the cleaning assembly 400, simplifying the operation of cleaning the hair, improving the reliability of the equipment operation, and being conducive to improving the user's satisfaction.

[0068] In the embodiment, the second comb tooth part 4102 is arranged towards the dustproof member 310, and dirt such as hair clumps on the periphery of the dustproof member 310 can be scraped off by the second comb tooth part 4102, thereby reducing the problem that the dirt such as hair clumps enters the inside of the dustproof member 310 and affects the smoothness of the power connection between the transmission assembly 300 and the comb tooth part 410, such as reducing the phenomenon that the dirt such as hair clumps approaches the transmission rod 320 through the dustproof member 310 and causes the transmission rod 320 and the fixing frame 420 to be blocked and stuck in the transmission connection, thereby enabling the transmission assembly 300 and the cleaning assembly 400 to be smoothly and reliably power connected, so that the cleaning assembly 400 can be smoothly moved relative to the filter screen 140, reducing the problem that the performance may be reduced or the equipment may be malfunctioned due to the blockage of the transmission assembly 300 and the cleaning assembly 400 by the dirt, enabling the equipment to still be smoothly operated after a long time of operation, and reducing the maintenance frequency.

[0069] In the above embodiment, as Figure 5 , Figure 6 and Figure 10As shown, the two comb elements 410 form an avoidance space 416 for avoiding the transmission assembly 300, that is, the part of the transmission assembly 300 between the two comb elements 410 is connected with the comb elements 410 through the avoidance space 416. The dustproof member 310 is also located in the avoidance space 416, and the second comb portion 4102 is arranged towards the dustproof member 310, that is, the second comb portion 4102 is located on the side of the comb element 410 facing the avoidance space. Thus, by using the second comb portion 4102, the dirt such as hair balls on the side of the dustproof member 310 in the avoidance space 416 can be scraped off, reducing the problem of the dirt such as hair balls affecting the smoothness of the power connection between the transmission rod 320 and the fixed frame 420 inside the dustproof member 310, such as reducing the phenomenon of the transmission rod 320 and the fixed frame 420 being blocked or jammed in threaded transmission connection caused by the dirt such as hair balls, thereby enabling the transmission assembly 300 and the cleaning assembly 400 to be smoothly and reliably connected in power, so that the cleaning assembly 400 can move smoothly relative to the filter screen 140, reducing the problem of performance degradation or equipment failure that may be caused by the blocking of the transmission assembly 300 and the cleaning assembly 400 due to pollution, so that the equipment can still run smoothly after a long time of operation, reducing the maintenance frequency. That is, in the present embodiment, by using the dual dustproof effect of the dustproof member 310 and the second comb portion 4102, the cleanliness of the environment near the power connection structure of the transmission assembly 300 and the cleaning assembly 400 can be greatly improved, such as the cleanliness of the environment near the transmission connection structure of the transmission rod 320 and the fixed frame 420, further reducing the problem of performance degradation or equipment failure that may be caused by the blocking of the transmission assembly 300 and the cleaning assembly 400 due to dirt.

[0070] Further, the dustproof member 310 can be a dust cover or a dust plate, and the dustproof member 310 is provided or formed with an avoidance passage away from the filter screen 140, and the fixed frame 420 of the cleaning assembly 400 is sleeved on the transmission rod 320 through the avoidance passage and connected in transmission with the transmission rod 320. It can be understood that the cleaning assembly 400 can move relative to the transmission rod 320 along the avoidance passage to move relative to the filter screen 140.

[0071] In some embodiments, the air conditioning device 10 is provided with an air inlet 130 on the main body 100, and a filter screen 140 is in communication with the air inlet 130. The air inlet 130 is located at the central position of the filter screen 140, so that the dirt such as hair filtered by the filter screen 140 is mostly concentrated in the middle of the filter screen 140, and the middle position of the filter screen 140 is located between the two comb teeth members 410, and the transmission assembly 300 is also located between the two comb teeth members 410. Therefore, there is a possibility that the transmission assembly 300 cannot rotate smoothly due to the large amount of dirt such as hair near the transmission assembly 300, and the cleaning assembly 400 cannot run smoothly relative to the filter screen 140. For example, the transmission assembly 300 includes a transmission rod 320 in threaded transmission with the comb teeth member 410. If there is a large amount of dirt such as hair in the avoidance space 416, the dirt such as hair will be wound around the transmission rod 320, or the transmission rod 320 and the cleaning assembly 400 connected by threaded transmission will be stuck, so that the cleaning assembly 400 cannot run smoothly. Therefore, the dustproof member 310 is arranged on part of the circumference of the transmission rod 320, which blocks the dirt such as hair from approaching the transmission rod 320, so as to reduce the possibility that the dirt such as hair causes the transmission rod 320 and the cleaning assembly 400 to be stuck or blocked at the transmission connection position, and enables the cleaning assembly 400 to move smoothly relative to the filter screen 140. The second comb tooth part 4201 is arranged on the side of the comb teeth member 410 facing the avoidance space 416, i.e. the second comb tooth part 4201 faces the dustproof member 310 located in the avoidance space 416, which scrapes the dirt such as hair on the circumference of the dustproof member 310 in the avoidance space 416, reduces the possibility that the dirt such as hair approaches the transmission rod 320 through the dustproof member 310, and enables the transmission rod 320 and the cleaning assembly 400 to be connected by power smoothly, so as to enable the cleaning assembly 400 to move smoothly relative to the filter screen 140. This automatic cleaning mode reduces the need for manual intervention and reduces the complexity of maintenance, providing users with a more convenient use experience. At the same time, the dual cleaning protection of the dustproof member 310 and the second comb tooth part 4201 can further reduce the possibility of performance degradation or equipment failure of the transmission assembly 300 and the cleaning assembly 400 caused by dirt blockage.

[0072] In some embodiments, as shown in Figure 14 , Figure 15 , Figure 16 The comb teeth member 410 includes a connecting part 417 and an elastic connecting part 418. The connecting part 417 is connected with the fixed frame 420, and the elastic connecting part 418 connects the top of the first comb tooth part 4101 and the connecting part 417. The elastic connecting part 418 is configured to be elastically deformed under the abutment of the filter screen 140 to make the first comb tooth part 4101 abut against the filter screen 140.

[0073] Due to the dimensional tolerance of the filter screen 140 in the thickness direction, by arranging the elastic abutment part 418, the first comb part 4101 of the comb part 410 can be kept in a pressed state with the filter screen 140 at all times. For example, when an external force acts on the cleaning assembly 400, for example, when the first comb part 4101 abuts against the filter screen 140, the elastic abutment part 418 can absorb and buffer these forces, so as to keep the first comb part 4101 and the filter screen 140 in a pressed state at all times, and reduce the possibility of damage to the first comb part 4101 and other components, so that the comb part 410 has good cleaning effect, and is conducive to prolonging the service life of the cleaning assembly 400. At the same time, the arrangement makes the friction between the first comb part 4101 and the filter screen 140 not too large to cause excessive noise and excessive load of the power assembly, improves the comfort of use of the user, and improves the stability of operation of the power assembly.

[0074] Further, in order to reliably abut the first comb part 4101 against the filter screen 140, a pre-pressing amount is usually arranged for the first comb part 4101. However, due to the dimensional tolerance of the filter screen 140 in the thickness direction in the actual application scene, there is a possibility that the first comb part 4101 cannot be reliably pressed against the filter screen 140. Therefore, by arranging the elastic abutment part 418, the elastic abutment part 418 has good deformation ability, which, in combination with the pre-pressing amount of the first comb part 4101, can keep the first cleaning tooth 411 of the first comb part 4101 in close contact with the filter screen 140, so as to improve the cleaning effect. At the same time, the friction between the first cleaning tooth 411 of the first comb part 4101 and the filter screen 140 will not be too large to cause excessive noise and excessive load of the power assembly, improve the comfort of use of the user, and improve the stability of operation of the power assembly.

[0075] In the above embodiment, the elastic abutment part 418 is in a plate structure, and the thickness of the elastic abutment part 418 is shown as D0 in FIG. 11, wherein the thickness of the elastic abutment part 418 ranges from 0.8 mm to 1.2 mm. Figure 16 The plate-shaped elastic abutment part 418 has good elastic deformation ability and a large connection area, so that the connection between the first comb part 4101 and the connecting part 417 can be reliably realized through the elastic abutment part 418, which is conducive to improving the overall reliability of the comb part 410.

[0076] By reasonably setting the thickness range of the elastic connecting part 418, the elastic deformation ability of the elastic connecting part 418 can be controlled within a certain range. In combination with the pre-pressing amount of the first cleaning tooth 411 of the first comb tooth part 4101, the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 can be kept in close contact, and the cleaning operation can be better achieved. At the same time, the friction between the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 will not be too large to cause excessive noise and excessive load of the power assembly, thereby improving the comfort of use of the user and improving the stability of the operation of the power assembly. Specifically, the thickness D0 of the elastic connecting part 418 can be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, or any size within the range of 0.8 mm to 1.2 mm.

[0077] Further, the elastic connecting part 418 is arranged at an angle with the connecting part 417, that is, the elastic connecting part 418 is arranged at an angle with the connecting part 417. Thus, when the first cleaning tooth 411 of the first comb tooth part 4101 contacts and is stressed by the filter screen 140, the elastic connecting part 418 and the connecting part 417 are easily deformed at the bending part, so that the angle between the elastic connecting part 418 and the connecting part 417 changes, thereby adjusting the fitting state of the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140, so that the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 are kept in close contact, and the problem that the friction between the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 is not too large to cause excessive noise and excessive load of the power assembly does not occur.

[0078] Further, the elastic connecting part 418 is arranged at an angle with the first comb tooth part 4101, that is, the elastic connecting part 418 is arranged at an angle with the first comb tooth part 4101. Thus, when the first cleaning tooth 411 of the first comb tooth part 4101 contacts and is stressed by the filter screen 140, the elastic connecting part 418 and the first comb tooth part 4101 are easily deformed at the bending part, so that the angle between the elastic connecting part 418 and the first comb tooth part 4101 changes, thereby adjusting the fitting state of the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140, so that the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 are kept in close contact, and the problem that the friction between the first cleaning tooth 411 of the first comb tooth part 4101 and the filter screen 140 is not too large to cause excessive noise and excessive load of the power assembly does not occur.

[0079] It can be understood that the elastic connecting part 418 can be arranged at an angle with the connecting part 417, or the elastic connecting part 418 can be arranged at an angle with the first comb tooth part 4101, or one end of the elastic connecting part 418 can be arranged at an angle with the connecting part 417, and the other end of the elastic connecting part 418 can be arranged at an angle with the first comb tooth part 4101.

[0080] In some embodiments, as shown in Figure 5 The comb tooth piece 410 and the fixing frame 420 are in a split structure, and the comb tooth piece 410 and the fixing frame 420 are configured to be detachably connected. In this design, the comb tooth piece 410 and the fixing frame 420 can be disassembled and separated for individual maintenance or replacement, which helps to improve the maintenance efficiency and save the maintenance cost. Specifically, the comb tooth piece 410 and the fixing frame 420 can be detachably connected by at least one of a bolt structure, a clamping structure, a plug-in structure, a mortise and tenon structure, and a magnetic attraction structure. Specifically, as shown in Figure 4 The cleaning assembly further includes a connecting screw 440, and zero comb tooth pieces 410 are fixed on the fixing frame 420 by the connecting screw 440, which is convenient to disassemble. Figure 5 The comb tooth piece 410 and the fixing frame 420 are connected by the connecting screw 440.

[0081] In some embodiments, as shown in Figure 10 The comb tooth piece 410 and the fixing frame 420 are in an integrated structure, such as an integrally formed structure. This design improves the structural strength and stability of the cleaning assembly 400, eliminates the loosening or misalignment problem caused by the connection between multiple independent components, simplifies the manufacturing process, reduces the assembly steps and time, and helps to reduce the production cost. In addition, the integrally formed structure reduces potential failure points and improves the durability and reliability of the cleaning assembly 400. Since there is no extra connecting piece, the cleaning assembly 400 can more efficiently transfer force and motion during operation, improving its work efficiency.

[0082] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 3 The air conditioning device 10 further includes a collection box 150 located below the filter screen 140, and the comb tooth piece 410 is configured to clean the dirt on the filter screen 140 and collect the dirt into the collection box 150. After the first cleaning tooth 411 scrapes the dirt on the filter screen 140, the dirt will fall and collect in the collection box 150 located below the filter screen 140 under the action of gravity. At the same time, the dirt can gradually accumulate and finally collect in the collection box 150 during the movement of the comb tooth piece 410 towards the collection box 150, so as to realize the centralized collection of the dirt during the cleaning of the filter screen 140 by the cleaning assembly 400, prevent secondary pollution, and enable the cleaning assembly 400 to maintain a clean state for a long time, so that the device can operate efficiently for a long time. At the same time, through the collection box 150, the dirt can be conveniently collected and treated, so that the user can clean the collected dirt more conveniently, and only needs to empty the collection box 150 periodically, which is convenient to operate.

[0083] More specifically, the collecting box 150 is detachably connected with the main body 100, for example, the collecting box 150 is detachably connected with the main body 100 through a pulling mode, a clamping mode, a plug-in mode, etc. Thus, the collecting box 150 and the main body 100 are convenient to disassemble and assemble, and the dirt collected in the collecting box 150 is convenient to process, for example, the collecting box 150 is taken out from the main body 100, and the dirt collected in the collecting box 150 is poured out, which is convenient to operate. Meanwhile, the collecting box 150 is convenient to clean. Specifically, the first cleaning tooth 411 is located on the side of the comb tooth piece 410 close to the collecting box 150, so that the first cleaning tooth 411 can scrape the dirt on the filter screen 140 and collect the dirt in the collecting box 150.

[0084] As shown in Figure 2 , Figure 3 and Figure 4 , the comb tooth piece 410 is further provided with a material pressing structure 430. The material pressing structure 430 is arranged on the side of the comb tooth piece 410 close to the collecting box 150, and the material pressing structure 430 is used to press the dirt in the collecting box 150. The dirt in the dust box is compressed under the action of the material pressing structure 430, so as to increase the capacity utilization of the collecting box 150. In this way, more dirt can be accommodated without increasing the volume of the collecting box 150, the period of emptying the collecting box 150 is prolonged, and the maintenance frequency of the user is reduced. Meanwhile, the arrangement of the material pressing structure 430 can reduce the phenomenon of loose accumulation of the dirt in the collecting box 150, so that the dirt is relatively compact in the collecting box 150. The possibility of scattering of the dirt when the collecting box 150 is emptied is reduced, and the secondary pollution of the dirt is further reduced.

[0085] As shown in Figure 14 , in the above embodiment, the first comb tooth part 4101 is located on the side of the material pressing structure 430 close to the filter screen 140, and the second comb tooth part 4102 is located on the side of the material pressing structure close to the filter screen. This arrangement makes the material pressing structure 430 not hinder the first comb tooth part 4101 and the filter screen 140 from abutting smoothly, and the material pressing structure 430 does not hinder the second comb tooth part 4102 and the partial power assembly from being arranged oppositely, so that the functions of the first comb tooth part 4101 and the second comb tooth part 4102 can be realized smoothly. Figure 2 and Figure 6As shown, the pressing structure 430 and the first cleaning tooth 411 are located on the side of the comb tooth piece 410 close to the collection box 150, and the bottom end of the pressing structure 430 is located below the bottom end of the first cleaning tooth 411. Thus, when the cleaning assembly 400 moves towards the collection box 150, the pressing structure 430 will extend into the collection box 150 in advance to compress the dirt in the collection box 150 in advance, so as to increase the capacity utilization of the collection box 150, provide a space for the dirt scraped by the first cleaning tooth 411 located behind the pressing structure 430 to continue to move towards the collection box 150, so that the collection box 150 can accommodate more dirt and reduce the possibility of dirt overflowing from the collection box 150, so that the space in the collection box 150 can be effectively utilized, further improve the capacity utilization of the collection box 150, reduce the frequency of the user emptying the collection box 150, and be more conducive to maintenance.

[0086] As shown in Figure 5 , Figure 7 in some embodiments, the pressing structure 430 includes a pressing plate 431 located at the bottom end, and the pressing plate 431 is arranged parallel to or inclined to the bottom wall of the collection box 150. Since the bottom end of the pressing structure 430 is in contact with the dirt in the collection box 150 in advance and directly, by arranging the pressing plate 431 parallel to the bottom wall of the collection box 150, or arranging the pressing plate 431 inclined to the bottom wall of the collection box 150, the projection area of the pressing plate 431 on the plane where the bottom wall of the collection box 150 is located is larger, which increases the contact area between the pressing structure 430 and the dirt in the collection box 150, and can improve the compression amount of the dirt in the collection box 150, which is conducive to further increasing the capacity utilization of the collection box 150, so that more dirt can be accommodated without increasing the volume of the collection box 150.

[0087] In some embodiments, as shown in Figure 7 , the pressing structure 430 further includes a connecting plate 432 bent with the pressing plate 431, the first end of the connecting plate 432 is connected with the pressing plate 431, and the second end of the connecting plate 432 is located above the first cleaning tooth 411. By bending the connecting plate 432 with the pressing plate 431, the pressing plate 431 has a larger contact area with the dirt in the collection box 150. By arranging the second end of the connecting plate 432 above the first cleaning tooth 411, the pressing structure 430 and the first cleaning tooth 411 do not interfere with each other, for example, the pressing structure 430 does not block the cleaning tooth, so that the cleaning tooth has good cleaning and anti-winding effects.

[0088] Further, the connecting plate 432 is connected to the pressing plate 431 near the side of the filter screen 140, so that the entire pressing structure 430 is located on the side of the first cleaning tooth 411 away from the filter screen 140. This design makes the connecting plate 432 not hinder the abutment of the first cleaning tooth 411 and the filter screen 140, so that the first cleaning tooth 411 has good cleaning effect. At the same time, the connecting plate 432 can hinder the dirt on the filter screen 140 from falling above the pressing plate 431, so that the pressing structure 430 has good cleaning performance, and the dirt on the filter screen 140 can be more concentratedly dropped into the collection box 150, reducing the possibility of secondary pollution of the dirt.

[0089] In some embodiments, as shown in Figure 5 and Figure 7 The pressing structure 430 further includes support plates 433 located on both sides of the connecting plate 432, and the support plates 433 connect the pressing plate 431 and the connecting plate 432. The arrangement of the support plates 433 can improve the reliability and stability of the connection between the connecting plate 432 and the pressing plate 431, improve the strength of the pressing structure 430, so that the pressing plate 431 has good ability to extrude dirt, and is not easy to be damaged, which is beneficial to prolong the service life of the pressing structure 430, and further improve the overall service life of the cleaning assembly 400. At the same time, the support plates 433 are located on the side of the second cleaning tooth 415 away from the part of the power assembly, so that the support plates 433 do not hinder the second cleaning tooth 415 from scraping the dirt near the part of the power assembly, so as to improve the length of time during which the equipment can run smoothly.

[0090] The pressing structure 430 has an opening on the side away from the filter screen 140. Since the opening is located away from the filter screen 140, the possibility of dirt on the filter screen 140 falling above the pressing plate 431 can be reduced, so as to improve the cleaning performance of the pressing structure 430, so that the dirt on the filter screen 140 can be more concentratedly dropped into the collection box 150, reducing the possibility of secondary pollution of the dirt. At the same time, the arrangement of the opening can reduce the material of the pressing structure 430, which is beneficial to save cost.

[0091] In some embodiments, as shown in Figure 14As shown, the comb tooth piece 410 is an integrated structure, such as the material pressing structure 430, the first comb tooth part 4101, the second comb tooth part 4102, the connecting part 417, the elastic connecting part 418, etc. on the comb tooth piece 410 are integrated into an integrated structure. This design improves the structural strength and stability of the comb tooth piece 410, eliminates the loosening or misalignment problems that may be caused by the connection between multiple independent parts, simplifies the manufacturing process, reduces the assembly steps and time, and is conducive to reducing production costs. In addition, the integrated structure reduces potential failure points and improves the durability and reliability of the comb tooth piece 410. Since there are no extra connecting parts, the comb tooth piece 410 can more efficiently transfer force and motion during operation, improving its work efficiency. It can be understood that, as shown in Figure 2 and Figure 3 , the comb tooth piece 410 can reciprocate relative to the filter screen 140, such as the comb tooth piece 410 can move up and down relative to the filter screen 140 in the vertical direction. The vertical direction can be indicated by the arrow Z in Figure 2 , Figure 3 . Among them, the position of the comb tooth piece 410 relative to the filter screen 140 includes the extreme position close to the collection box 150 and the extreme position away from the collection box 150. Specifically, Figure 2 shows that the comb tooth piece 410 is in the extreme position close to the collection box 150 relative to the filter screen 140, that is, the comb tooth piece 410 runs to the bottom, Figure 3 shows that the comb tooth piece 410 is in the extreme position away from the collection box 150 relative to the filter screen 140, that is, the comb tooth piece 410 runs to the top. Specifically, when the comb tooth piece 410 runs to the lowest position relative to the filter screen 140 in the direction close to the collection box 150, as shown in Figure 2 , that is, the comb tooth piece 410 cannot continue to move in the direction close to the collection box 150, indicating that the comb tooth piece 410 runs to the extreme position close to the collection box 150 relative to the filter screen 140. When the comb tooth piece 410 runs to the highest position relative to the filter screen 140 in the direction away from the collection box 150, as shown in Figure 3 , that is, the comb tooth piece 410 cannot continue to move in the direction away from the collection box 150, indicating that the comb tooth piece 410 runs to the extreme position away from the collection box 150 relative to the filter screen 140. In actual application scenarios, the comb tooth piece 410 moves relative to the filter screen 140 and alternates between the extreme position close to the collection box 150 and the extreme position away from the collection box 150 to realize the reciprocating motion of the comb tooth piece 410 relative to the filter screen 140.

[0092] Specifically, when the comb tooth piece 410 runs downward relative to the filter screen 140, i.e. when the comb tooth piece 410 moves from the extreme position away from the collection box 150 to the extreme position close to the collection box 150, the comb tooth piece 410 interferes with the filter screen 140 to achieve the cleaning operation of the filter screen 140, and the scraped dirt is collected in the collection box 150, and the dirt in the collection box 150 is compressed by the pressing structure 430. When the comb tooth piece 410 runs to the extreme position close to the collection box 150, i.e. when the comb tooth piece 410 runs to the bottom, the comb tooth piece 410 will move upward for a short time, i.e. the comb tooth piece 410 will move away from the extreme position of the collection box 150 for a short time, and when the comb tooth piece 410 reaches the extreme position away from the collection box 150, i.e. when the comb tooth piece 410 runs to the top, the comb tooth piece 410 will continue to run toward the extreme position close to the collection box 150 for a short time, and the cycle will continue.

[0093] In some embodiments, as shown in Figure 2 、 Figure 11 、 Figure 12 and Figure 13 , the collection box 150 is located below the filter screen 140, the bottom edge of the filter screen 140 is spaced apart in the width direction of the filter screen 140, and the comb tooth piece 410 runs to the extreme position close to the collection box 150 relative to the filter screen 140, the tooth tip of the first cleaning tooth 411 is located below the tooth tip of the scale-resistant tooth 141, and the comb tooth piece 410 moves away from the collection box 150 along the extreme position to interfere with the scale-resistant tooth 141 to scrape the residual dirt on the comb tooth piece 410.

[0094] When the comb tooth piece 410 runs to the extreme position close to the collection box 150 relative to the filter screen 140, i.e. when the comb tooth piece 410 runs to the extreme position close to the collection box 150 relative to the filter screen 140, the tooth tip of the first cleaning tooth 411 is located below the tooth tip of the scale-resistant tooth 141, and the comb tooth piece 410 moves away from the collection box 150 along the extreme position to interfere with the scale-resistant tooth 141 to scrape the residual dirt on the comb tooth piece 410. Figure 2 、 Figure 13As shown, the tip of the first cleaning tooth 411 is located below the tip of the scale-inhibiting tooth 141. Therefore, when the comb member 410 moves from its extreme position near the collection box 150 to a position away from the collection box 150 under the drive of the power component—that is, when the comb member 410 moves towards the collection box 150 to below the filter screen 140 and then rises again to move away from the collection box 150—the scale-inhibiting tooth 141 can abut against the comb member 410. The scale-inhibiting tooth 141 can effectively scrape away residual dust, hair, and other dirt from the comb member 410, thus cleaning the comb member 410. Specifically, since the comb member 410 and the filter screen 140 are in close contact, when the comb member 410 moves upward again, the scale-inhibiting tooth 141 will scrape away hair and other dirt trapped between the filter screen 140 and the first cleaning tooth 411. This scraped-off dirt will fall off and be collected in the collection box 150 below. In other words, the anti-fouling tooth 141 can clean the first cleaning tooth 411 to improve the cleanliness of the comb component 410, making the comb component 410 cleaner after the cleaning cycle, thereby improving the overall efficiency and performance of the cleaning component 400.

[0095] This design enables the first cleaning tooth 411 of the cleaning component 400 to automatically clean the filter screen 140, while the scale-inhibiting tooth 141 on the filter screen 140 can self-clean the cleaning component 400. The two work together to clean each other, making the functions more diverse. Furthermore, this automated cleaning method reduces the need for manual intervention, lowers the complexity of maintenance, and provides users with a more convenient user experience.

[0096] Among them, such as Figure 13 As shown, the scale-inhibiting teeth 141 and the first cleaning teeth 411 are arranged alternately, that is, the gaps between the scale-inhibiting teeth 141 and the two adjacent first cleaning teeth 411 are arranged accordingly, and the gaps between the first cleaning teeth 411 and the two adjacent scale-inhibiting teeth 141 are arranged accordingly. This design allows the scale-inhibiting teeth 141 to reliably scrape the dirt remaining in the gaps between the two adjacent first cleaning teeth 411, thereby removing the residual dirt to the maximum extent, reducing the possibility of dirt remaining on the comb tooth 410, and improving the cleaning effect of the comb tooth 410.

[0097] More specifically, the tooth height of the scale-inhibiting tooth 141 is as follows: Figure 12 As shown in H2, the tooth height H2 of the scale-inhibiting tooth 141 ranges from 2 mm to 3 mm, and the spacing between two adjacent scale-inhibiting teeth 141 is as follows: Figure 12As shown in S2, the distance S2 between two adjacent scale-inhibiting teeth 141 ranges from 6mm to 7mm. By rationally designing the tooth height H2 of the scale-inhibiting teeth 141 and / or rationally setting the distance S2 between two adjacent scale-inhibiting teeth 141, the tips of the scale-inhibiting teeth 141 can smoothly penetrate into the gap between two adjacent first cleaning teeth 411. This allows the scale-inhibiting teeth 141 to effectively scrape away residual dirt in the gap between the two adjacent first cleaning teeth 411, resulting in a good dirt-scraping effect. Simultaneously, it reduces the risk of long, thin dirt such as hair becoming entangled in the scale-inhibiting teeth 141 during the cleaning comb part 410 process. This ensures that the scale-inhibiting teeth 141 maintain a high cleaning efficiency even after long-term operation, reducing potential performance degradation or equipment failure caused by scale-inhibiting teeth 141 becoming entangled, and providing users with a more reliable and low-maintenance user experience.

[0098] Specifically, the spacing S2 between two adjacent scale-inhibiting teeth 141 can be 6 mm, 6.5 mm, 7 mm, or any size from 6 mm to 7 mm. The tooth height H2 of the scale-inhibiting teeth 141 can be 2 mm, 2.5 mm, 3 mm, or any size from 2 mm to 3 mm.

[0099] Among them, such as Figure 12 As shown, the tips of the scale-inhibiting teeth 141 are configured as a second arc structure 142. This means that the scale-inhibiting teeth 141 on the filter screen 140 also have arc-shaped tips. This design makes the outer edge of the entire scale-inhibiting tooth 141 a relatively smooth curved surface structure, reducing the possibility of the scale-inhibiting teeth 141 having sharp corners that could scratch the user, thus improving user safety. Simultaneously, configuring the tips of the scale-inhibiting teeth 141 as a second arc structure 142 allows the tips of the second arc structure 142 to penetrate into the gaps between two adjacent first cleaning teeth 411, effectively scraping away residual dirt from the gaps between adjacent first cleaning teeth 411, improving the cleaning effect, and thus improving the cleanliness of the comb component 410.

[0100] Furthermore, the diameter of the second circular arc structure 142 is as follows: Figure 12 As shown in D2, the diameter D2 of the second arc structure 142 ranges from 1.4mm to 1.8mm. By reasonably setting the range of the diameter of the second arc structure 142, the tips of the scale-inhibiting teeth 141 have a good anti-scratch effect, while the scale-inhibiting teeth 141 have a good cleaning effect. Specifically, the diameter of the second arc structure 142 can be any size from 1.4mm, 1.6mm, 1.8mm, or 1.4mm to 1.8mm.

[0101] In some embodiments, such as Figure 11As shown, the filter screen 140 includes a frame 143 and a filter screen portion 144 embedded in the frame 143. The frame 143 provides structural support and stability, enabling the filter screen portion 144 to maintain its shape and position, thereby improving the stability and consistency of the filtering effect. In addition, this combined structure allows for the selection of different materials and techniques during the design and manufacturing process to optimize filtering performance.

[0102] Specifically, the frame 143 is integrally injection molded with the filter screen portion 144. The integrally injection molding process simplifies the production process, reduces production costs, improves manufacturing efficiency, and shortens the production cycle. Moreover, integrally injection molding eliminates seams or connection points between the frame 143 and the filter screen portion 144, thereby enhancing the strength and stability of the overall structure and reducing the risk of damage due to stress or pressure during use.

[0103] Specifically, in some embodiments, the filter screen portion 144 is a PET mesh or a stainless steel mesh. The mesh density of the filter screen portion 144 is 50 to 70 meshes per square inch. The mesh density of the filter screen portion 144 is set to 50 to 70 meshes per square inch, enabling the filter screen to effectively filter particles of a specific size while maintaining good flow properties. Specifically, the mesh density of the filter screen portion 144 can be set to 50, 60, 70 meshes per square inch, or any value within the range of 50 to 70 meshes per square inch.

[0104] In some embodiments, as shown in Figure 2 and Figure 3 The power assembly further includes a drive assembly 200 disposed in the main body 100, and a transmission assembly 300 disposed in the main body 100 and connected to the drive assembly 200, wherein the transmission assembly 300 is in threaded transmission with the cleaning assembly 400. The threaded transmission design can convert rotary motion into linear motion, and the threaded transmission of the cleaning assembly 400 has higher precision, enabling the cleaning assembly 400 to have stable speed and direction during transmission without sliding or deviation. The precision of the threaded transmission enables the cleaning assembly 400 to move in small steps, thereby achieving more comprehensive and uniform cleaning of the filter screen 140, enabling the cleaning assembly 400 to move smoothly and accurately along the surface of the filter screen 140 under the drive of the transmission assembly 300. This design not only improves the stability and reliability of the cleaning process, but also effectively reduces the problem of uneven cleaning and damage to the filter screen 140 that may occur during manual cleaning, making it suitable for widespread application.

[0105] In some embodiments, as shown in Figure 2 and Figure 3As shown, the transmission assembly 300 includes a transmission rod 320 rotatably arranged on the main body 100, and the transmission rod 320 is connected with the driving assembly 200, such as the transmission rod 320 penetrating the dustproof member 310 and being power-connected with the driving assembly 200. Among them, the transmission rod 320 can be a screw rod, such as Figure 5 As shown, the cleaning assembly 400 is provided with a threaded hole 421, such as the threaded hole 421 arranged on the fixing frame 420 of the cleaning assembly 400, and the cleaning assembly 400 is sleeved on the screw rod through the threaded hole 421 and is in threaded transmission with the screw rod, so that the cleaning assembly 400 can move along the axial direction of the screw rod under the driving of the screw rod and clean the filter screen 140. The transmission assembly 300 is designed to include a rotatable screw rod, and the cleaning assembly 400 is provided with a threaded hole 421 matched with the screw rod, so that the cleaning assembly 400 can be connected with the transmission rod through threaded transmission. When the transmission rod rotates, the cleaning assembly 400 moves along the axial direction of the transmission rod under the action of the thread. This design enables the cleaning assembly 400 to effectively perform linear motion under the driving of the transmission rod, thereby performing cleaning operation relative to the filter screen 140.

[0106] In some embodiments, as shown in Figure 2 、 Figure 3 and Figure 4 As shown, the driving assembly 200 includes a driving member 210, a driving gear 220 connected with the driving member 210, and a transmission gear 230 in transmission connection with the driving gear 220, and the screw rod has a transmission end, and the transmission gear 230 is in transmission connection with the transmission end to drive the rotation of the screw rod.

[0107] Among them, the driving assembly 200 is composed of the driving member 210, the driving gear 220 and the transmission gear 230. The driving member 210 can be a motor or other type of power device, which transmits power to the transmission gear 230 through the driving gear 220, and the transmission gear 230 is further connected with the transmission end of the screw rod, so as to realize the rotation driving of the screw rod. This design effectively transmits the power of the driving member 210 to the screw rod through the gear transmission system, so that the screw rod can stably and efficiently rotate. This structure not only improves the efficiency of the transmission system, but also makes the operation of the whole device more accurate and reliable.

[0108] Specifically, as shown in Figure 4As shown, in some of the embodiments, the driving assembly 200 further comprises at least one transition gear 240 connected in transmission between the driving gear 220 and the transmission gear 230. Thus, the power of the driving member 210 is transmitted to the screw through the driving gear 220, the transition gear 240 and the transmission gear 230 to drive the screw to rotate. The driving gear 220, the transition gear 240 and the transmission gear 230 are arranged to achieve the purpose of speed regulation. For example, by reasonably arranging the number of teeth of the driving gear 220, the transition gear 240 and the transmission gear 230, and reasonably arranging the transmission ratio, the screw can run smoothly at a suitable speed, thereby improving the stability of the operation of the cleaning assembly 400.

[0109] In some embodiments, as Figure 1 As shown, the main body 100 comprises a front cover 110 and a shell 120 connected detachably. For example, the shell 120 can be connected with the front cover 110 detachably by clamping, threaded connection, interference fit, etc. The shell 120 and / or the front cover 110 form the air inlet. For example, the front cover 110 and the shell 120 are connected to jointly enclose the air inlet in communication with the filter screen 140. For another example, the air inlet is directly arranged on the front cover 110. For another example, the air inlet is directly arranged on the shell 120. Here, only examples are given for illustration, and it is not indicated or implied that the arrangement of the air inlet can only be as such. Specifically, the filter screen 140 is arranged in the shell 120, the driving assembly 200 is arranged in the shell 120, and the transmission assembly 300 is arranged in the shell.
