[0067] Reference below Figure 1-Figure 18 An air inlet assembly 100 of an air treatment device according to an embodiment of the present invention is described.

[0068] like Figure 1-Figure 18 As shown, the air inlet assembly 100 of the air treatment device according to the embodiment of the present invention comprises: an air inlet housing 10, a filter 50, the air inlet housing 10 is used to define an air inlet cavity 101, and the air inlet housing 10 comprises a connector 11, the connector 11 defines an air inlet channel 111, the air inlet channel 111 is connected with the air inlet cavity 101, and thus the air enters the air inlet cavity 101 through the air inlet channel 111. The filter 50 is disposed in the air inlet cavity 101, and is used to filter the air entering the air inlet cavity 101 from the air inlet channel 111, and can filter the air to purify the air.

[0069] The air inlet assembly 100 of the air treatment device also includes a charging module 60, which is arranged on the connecting head 11, and the charging module 60 includes a first electrode 61 and a second electrode 62. The first electrode 61 and the second electrode 62 are arranged relative to each other, and can generate a high-voltage electric field in the air inlet channel 111 to achieve corona discharge, effectively sterilize, and play a role in pre-cleaning the air, thereby improving the air purification effect, and at the same time can reduce the workload of the filter element 50, increase the service life of the filter element 50, and reduce maintenance costs.

[0070] According to the air inlet assembly 100 of the air treatment device according to the embodiment of the present invention, by arranging a charging module 60 capable of corona discharge in the air inlet channel 111, and arranging a filter element 50 in the air inlet chamber 101, and the air inlet channel 111 is connected to the air inlet chamber 101, the air can be first treated by the corona discharge generated by the charging module 60 and then flow through the filter element 50, which can improve the air purification effect and reduce the workload of the filter element 50, thereby increasing the service life of the filter element 50 and reducing the maintenance cost; in addition, the charging module 60 and the filter element 50 are both installed in the air inlet shell 10, and the charging module 60 and the filter element 50 cooperate with each other to achieve air purification, with a simple structure and easy assembly, which is conducive to improving production and assembly efficiency.

[0071] In some examples, the first electrode 61 may be a pointed electrode, the second electrode 62 is disposed on the periphery of the first electrode 61 , and the second electrode 62 is spaced apart from the first electrode 61 , or the second electrode 62 may be a pointed electrode, and the first electrode 61 is disposed on the periphery of the second electrode 62 .

[0072] Among them, corona discharge can be achieved by applying a high voltage to a pointed electrode to generate an electric field. The electric field can ionize gas molecules in the air. The ionized gas molecules will react with particulate matter or pollutants in the air to form larger particles. These larger particles will settle due to their heavy weight. The filter element 50 of the air conditioner can capture the particles to purify the air. At the same time, the ionized gas molecules will also attach to the tiny particles in the air, thereby increasing their weight, making the tiny particles easier to be captured by the filter.

[0073] In addition, corona discharge can decompose organic pollutants through electrochemical reactions, that is, when an electric field is applied to organic matter in the air, the organic matter will undergo oxidation or reduction reactions, thereby decomposing the organic matter into harmless substances.

[0074] It can be understood that the first electrode 61 and the second electrode 62 cooperate with each other, that is, using the corona discharge technology, pollutants and odors in the air can be removed, thereby improving the cleaning effect of the air.

[0075] like Figure 2As shown, according to some embodiments of the present invention, the air inlet shell 10 also includes a shell body 12, and the shell body 12 is used to define the air inlet cavity 101, thereby defining the flow path of the air, and is conducive to the installation of air purification components such as the filter 50 on the flow path of the air, which can improve the space utilization rate in the air inlet shell 10 and is conducive to the miniaturization of the product.

[0076] Among them, the connecting head 11 includes a first connector 20 and a second connector 30, the first connector 20 and the second connector 30 are detachably connected, the first connector 20 can be fixedly connected to the shell body 12, and the second connector 30 can be used to connect the air inlet pipe, or the second connector 30 can be fixedly connected to the shell body 12, and the first connector 20 is used to connect the air inlet pipe, thereby ensuring the normal air intake effect of the air intake assembly 100, facilitating the loading and unloading of the charging module 60, which is beneficial to improving the production and assembly efficiency of the product.

[0077] The first electrode 61 and the second electrode 62 can be arranged on the first connector 20, and the first electrode 61 and the second electrode 62 can also be arranged on the second connector 30. The first connector 20 is connected to the second connector 30 to complete the assembly of the charging module 60, which can improve the convenience of installing the charging module 60.

[0078] like Figure 2 As shown, in some examples, the first connector 20 includes: a first annular plate 21 and a mounting seat 23, the first annular plate 21 defines an installation space, the installation space may be a part of the air inlet channel 111, or the air inlet channel 111 as a whole may be located in the installation space, the mounting seat 23 is arranged in the installation space, and the first electrode 61 is arranged on the mounting seat 23, and the second electrode 62 is arranged on the first annular plate 21, so that the second electrode 62 can be arranged around the periphery of the first electrode 61, which is beneficial to improve the corona discharge effect of the first electrode 61, and is beneficial to the particulate matter in the air to fully react with the negative ions generated by the corona discharge in the process of entering the air inlet chamber 101, thereby improving the air purification effect.

[0079] like Figure 2 As shown, in some examples, the first electrode 61 can form a pointed electrode with good discharge effect, and the second electrode 62 can form a ring electrode. The second electrode 62 is arranged on the outer periphery of the first electrode 61, and the first electrode 61 and the second electrode 62 are arranged at intervals, so that the electric field between the first electrode 61 and the second electrode 62 can be evenly distributed, which can improve the corona discharge effect of the first electrode 61, and is beneficial for the particulate matter in the air to fully react with the negative ions generated by the corona discharge in the process of entering the air inlet chamber 101, thereby improving the air purification effect.

[0080] In other examples, the second electrode 62 may be formed into a plate-shaped electrode or a pointed electrode, and there are multiple second electrodes 62 , which are arranged at equal intervals around the periphery of the first electrode 61 , thereby reducing production costs.

[0081] like Figure 7 As shown, in some examples, the mounting seat 23 may form a strip-shaped structure, and the mounting seat 23 extends along the radial direction of the first annular plate 21, and one end of the mounting seat 23 (such as Figure 7 The left end) is connected to the inner wall surface of the first annular plate 21, and the other end of the mounting seat 23 (such as Figure 7 The right end) is located in the central area of ​​the installation space, which can make the electric field between the first electrode 61 and the second electrode 62 evenly distributed, thereby improving the corona discharge effect of the first electrode 61, and is beneficial for the particulate matter in the air to fully react with the negative ions generated by the corona discharge during the process of entering the air inlet chamber 101, thereby improving the air purification effect.

[0082] like Figure 5 As shown, in some examples, the first electrode 61 is located at the center of the installation space, that is, the first electrode 61 is arranged at the other end of the mounting seat 23 (such as Figure 5 The right end of the first electrode 61 is arranged at equal intervals everywhere, so that the electric field between the first electrode 61 and the second electrode 62 is evenly distributed, which can improve the corona discharge effect of the first electrode 61, and is beneficial for the particulate matter in the air to fully react with the negative ions generated by the corona discharge during the process of entering the air inlet chamber 101, thereby improving the air purification effect.

[0083] like Fig.14 As shown, in some examples, the air inlet assembly 100 of the air treatment device also includes: a protective cover 70, the protective cover 70 is arranged on the mounting seat 23, and a mounting cavity 701 is defined between the protective cover 70 and the mounting seat 23, and the first electrode 61 is arranged in the mounting cavity 701, which can prevent the first electrode 61 from being directly exposed to the air inlet channel 111, thereby improving the protection of the first electrode 61 and reducing the probability of dust accumulation on the first electrode 61, which is conducive to maintaining the corona discharge effect of the first electrode 61 for a long time, thereby ensuring the clean wind effect of the charging module 60 for a long time, and reducing the maintenance frequency of the charging module 60, thereby improving the user experience.

[0084] Among them, the protective cover 70 has a through hole 711, and the through hole 711 can connect the installation cavity 701 and the air inlet channel 111. That is, by setting the through hole 711, the end of the protective cover 70 can form a hollow structure, which can improve the release efficiency of the negative ions generated by the corona discharge of the first electrode 61, and thus facilitate the particulate matter in the air to fully react with the negative ions in the process of entering the air inlet cavity 101, thereby improving the air purification effect. At the same time, the protective cover 70 is set to cover the first electrode 61, which can prevent the first electrode 61 from causing harm to the human body during the disassembly and assembly of the connecting head 11, thereby improving the safety of the product.

[0085] like Fig.12 and Fig.15 As shown, in some examples, a bypass channel 702 and a wire outlet 721 are further defined between the protective cover 70 and the mounting seat 23. The bypass channel 702 extends along the length direction of the mounting seat 23 (eg, Fig.15 , and avoids one end of the passage 702 (as shown in the left and right directions). Fig.15 The right end of the avoidance channel 702 is connected to the installation cavity 701, and the other end of the avoidance channel 702 (such as Fig.15 The left end as shown in the figure is connected to the wire outlet 721 , and the connecting wire 611 of the first electrode 61 is passed through the avoidance channel 702 .

[0086] In the above technical solution, by setting the avoidance channel 702 and the wire outlet 721, the arrangement of the connecting wire 611 is made neater, and the connecting wire 611 is prevented from being exposed to the air inlet channel 111 to affect the cleaning effect of the air, thereby improving the reliability of the charging module 60. The connecting wire 611 passes through the wire outlet 721 to realize the electrical connection between the first electrode 61 and the power supply, so as to ensure the normal operation of the charging module 60.

[0087] like Figure 3 , Figure 5 and Figure 7 As shown, in some examples, the mounting seat 23 defines a mounting slot 231, and the mounting slot 231 is along the length direction of the mounting seat 23 (such as Figure 3 The first electrode 61 extends in the mounting groove 231.

[0088] For example, the first electrode 61 can be directly bonded into the mounting groove 231 , or fixed into the mounting groove 231 by a snap-fit ​​method, etc., to prevent the first electrode 61 from shaking during discharge, thereby improving the working stability of the charging module 60 .

[0089] The two oppositely disposed groove side walls of the mounting groove 231 are respectively provided with guide grooves 232, and the guide grooves 232 extend along the length direction of the mounting seat 23. The protective cover 70 has two guide ribs 731, which are arranged opposite to each other, and the guide ribs 731 correspond to the guide grooves 232 in position. The guide ribs 731 and the guide grooves 232 are slidably matched, which not only facilitates the connection between the protective cover 70 and the mounting seat 23, but also enables the protective cover 70 to be slidably connected in one dimensional direction (such as Figure 2 The limit in the front-to-back direction (as shown in the figure) can improve the connection effect between the protective cover 70 and the mounting base 23, prevent the protective cover 70 from being separated from the mounting base 23, and improve the reliability of the charging module 60.

[0090] like Figure 3 As shown, in some examples, one end of the mounting base 23 close to the center of the mounting space (such as Figure 3 The protective cover 70 is provided with a limit member 233. During the installation of the protective cover 70, the protective cover 70 moves relative to the mounting seat 23 in a direction close to the center of the mounting space (such as Figure 3 The protective cover 70 is slid from left to right as shown in the figure until it abuts against the limiting member 233, thereby preventing the protective cover 70 from excessively sliding and disengaging from the mounting base 23, thereby improving the reliability of the charging module 60.

[0091] It should be noted that the limiting member 233 may be a limiting plate, and the limiting plate may be a hollow plate. After the protective cover 70 is installed, the limiting plate abuts against the protective cover 70 to limit the protective cover 70.

[0092] There may also be two limit plates 233, which are located on opposite sides of the protective cover 70 (eg Figure 3 The first electrode 61 is located between the two limiting plates, so that the limiting member 233 can limit the protective cover 70 while making the protective cover 70 evenly stressed, thereby improving the limiting effect of the protective cover 70.

[0093] In addition, the stopper 233 can be integrally formed, and the shape of the stopper 233 is consistent with the end of the protective cover 70 close to the center of the installation space (such as Figure 3 The shape of the right end of the protective cover 70 can be matched, which can increase the contact area between the limiting member 233 and the protective cover 70, and further improve the limiting effect of the protective cover 70.

[0094] like Fig.15 As shown, in some examples, one end of the guide rib 731 close to the center of the installation space (such as Fig.15 The right end as shown in the figure may have a guiding slope 7311, which can guide the guiding rib 731 and facilitate the plug-in fit between the guiding rib 731 and the guiding groove 232.

[0095] The end of the guide groove 232 away from the center of the installation space (such as Figure 3 The right end as shown in the figure may also have a guiding slope 7311, which can also play a guiding role for the guiding rib 731, so as to facilitate the plug-in fit between the guiding rib 731 and the guiding groove 232.

[0096] Of course, the end of the guide rib 731 close to the center of the installation space and the end of the guide groove 232 away from the center of the installation space can be respectively provided with a guide slope 7311, and the inclination directions of the two guide slopes 7311 are the same, which can improve the guiding effect of the guide rib 731, facilitate the plug-in cooperation between the guide rib 731 and the guide groove 232, and facilitate the loading and unloading of the protective cover 70.

[0097] like Fig.15 As shown, in some examples, the protective cover 70 includes: a guide section 73 and a first cover body 71, the guide section 73 is along the length direction of the mounting seat 23 (such as Fig.15 The guide section 73 is slidably matched with the mounting seat 23, so that the protective cover 70 can be moved relative to the mounting seat 23 in a direction close to the center of the installation space (such as Figure 3 Sliding the protective cover 70 in the direction from left to right as shown in the figure is beneficial to the installation of the protective cover 70.

[0098] One end (eg, Fig.16 The first cover plate 71 is connected to the mounting seat 23, and a mounting cavity 701 is defined between the first cover body 71 and the mounting seat 23. By installing the first electrode 61 into the mounting cavity 701, the first electrode 61 can be confined in the center of the mounting space, which is convenient for operation. At the same time, the first cover plate and the mounting seat 23 cooperate to cover the first electrode 61, which can improve the protection effect of the first electrode 61, increase the service life of the first electrode 61, and prevent the operator from directly contacting the first electrode 61 when maintaining the product, thereby improving the safety of the product.

[0099] Among them, the through hole 711 is arranged on the first cover body 71, and the through hole 711 can connect the air inlet channel 111 and the installation cavity 701, which is beneficial to the outward diffusion of negative ions generated by corona power generation of the first electrode 61, and further beneficial to the particulate matter in the air to fully react with the negative ions generated by corona discharge in the process of entering the air inlet cavity 101, which can improve the air purification effect.

[0100] like Figure 4 and Fig.12As shown, in some examples, the first joint 20 also includes a first outer ring plate 22, which is sleeved on the outside of the first annular plate 21, and the first outer ring plate 22 is connected to the first annular plate 21, wherein the first outer ring plate 22 has an opening 221, and the opening 221 is connected to the installation space, so that the first cover body 71 and the guide section 73 can extend into the installation space through the opening 221, which is conducive to the installation of the protective cover 70 and is easy to operate.

[0101] In addition, by providing the opening 221, and the opening 221 is located on the side of the first joint 20, the protective cover 70 can enter the installation space from the side of the first joint 20 to reach the designated installation position to complete the installation, without the need for the protective cover 70 to be moved along the axial direction of the first annular plate 21 (such as Figure 4 The front and rear directions shown in the figure can be used to enter the installation space, which can make full use of the space and facilitate operation.

[0102] like Fig.12 and Fig.15 As shown, in some examples, the protective cover 70 further includes: a second cover body 72, the second cover body 72 has a thickness direction (such as Fig.15 side (as shown in the left and right directions) Fig.15 The right side shown in FIG. 1 and the length direction of the guide section 73 (as shown in FIG. Fig.15 The other end (as shown in the left and right directions) Fig.15 The left end of the protective cover 70 is connected, and the second cover body 72 is connected to the first outer ring plate 22 by clamping, and is used to open and close the opening 221, that is, when the first cover body 71 abuts against the limiting member 233, the second cover body 72 is clamped with the first outer ring plate 22, so that the installation of the protective cover 70 can be realized and the fixing effect of the protective cover 70 can be improved.

[0103] In some examples, a sealing strip may be provided on the outer edge of the second cover body 72. After the second cover body 72 is snapped onto the first outer ring plate 22, the sealing strip may be located between the outer edge of the second cover body 72 and the inner edge of the opening 221, thereby sealing the opening 221 and improving the sealing effect on the connector 11. At the same time, the second cover body 72 may be interference fit with the edge of the opening 221, thereby improving the fixing effect on the protective cover 70.

[0104] Among them, the sealing strip can be made of flexible materials such as silicone or rubber. Since its surface has adsorption ability, it can increase the resistance between the second cover body 72 and the opening 221, further improve the fixing effect of the protective cover 70, and improve the working stability of the charging module 60.

[0105] like Fig.15 As shown, in some examples, the second cover 72 faces one side of the guide section 73 (eg Fig.15The right side of the figure is shown in the figure, and two hooks 722 are provided. The two hooks 722 are arranged at intervals in the circumferential direction of the first outer ring plate 22, and the hook heads of the two hooks 722 are arranged back to back. When the first cover body 71 abuts against the limiting member 233, the hook heads of the two hooks 722 are respectively engaged with the two opposite edges of the opening 221, so that the second cover body 72 can be engaged with the first outer ring plate 22, thereby realizing the installation of the protective cover 70, improving the fixing effect of the protective cover 70, preventing the protective cover 70 from sliding out through the opening 221 to disengage from the mounting seat 23, and facilitating operation.

[0106] It is understandable that the number of hooks 722 can be greater, and multiple hooks 722 are arranged at intervals along the edge of the second cover plate. When the first cover body 71 abuts against the limiting member 233, the hook heads of the multiple hooks 722 are respectively engaged with the edges of the opening 221, which can improve the engaging effect between the second cover body 72 and the first outer ring plate 22, thereby improving the fixing effect of the protective cover 70.

[0107] like Figure 2 and Fig.14 As shown, in some examples, the second joint 30 includes: a second annular plate 31 and a second outer ring plate 32, the second annular plate 31 can define a portion of the air inlet channel 111, or the entire air inlet channel 111 is located in the second annular plate 31, the second outer ring plate 32 is sleeved on the outside of the second annular plate 31, and the second outer ring plate 32 is connected to the second annular plate 31.

[0108] Among them, the first outer ring plate 22 can be sleeved on the outer side of the second outer ring plate 32, or the second outer ring plate 32 can be sleeved on the outer side of the first outer ring plate 22, and the first outer ring plate 22 and the second outer ring plate 32 can be detachably connected, so that the first joint 20 and the second joint 30 can be detachably connected, and the second outer ring plate 32 has an avoidance gap 321, and the avoidance gap 321 is used to avoid the protective cover 70, that is, the avoidance gap 321 corresponds to the position of the opening 221, so that the protective cover 70 can enter the installation space through the avoidance gap 321 and the opening 221 in turn, which is conducive to the installation of the protective cover 70.

[0109] like Figure 2 As shown, in some examples, the outer periphery of the second outer ring plate 32 is provided with a bent portion 33, and the bent portion 33 is oriented toward the direction close to the first joint 20 (such as Figure 2 The outer periphery of the first outer ring plate 22 extends in a direction away from the second joint 30 (as shown in the figure from the back to the front). Figure 2 The second connector 30 is recessed (from the back to the front direction as shown) to form a groove 24, and the position of the groove 24 corresponds to the position of the bent portion 33, so that the bent portion 33 can be inserted into the groove 24 during the installation process of the second connector 30.

[0110] Among them, the outer wall surface of the bending portion 33 has a locking protrusion 331, and the side wall of the groove 24 has a through-hole 241. After the bending portion 33 and the groove 24 are plugged into each other, the locking protrusion 331 and the through-hole 241 are snap-fitted into each other, which can realize the connection between the first connector 20 and the second connector 30, and can improve the fixing effect of the second connector 30, which is convenient for operation.

[0111] It should be noted that the number of the bending portions 33 and the grooves 24 can both be one, which is convenient for processing, can reduce production costs, and can save space and facilitate loading and unloading; of course, the number of the bending portions 33 and the grooves 24 can be multiple respectively, and the multiple grooves 24 are arranged at intervals around the outer periphery of the first outer ring plate 22, and the protrusions 331 on the multiple bending portions 33 are snap-fitted with the through-holes 241 on the groove side walls of the multiple grooves 24 in a one-to-one correspondence.

[0112] In some examples, the first electrode 61 and the second electrode 62 may be disposed on the first connector 20, and since after the first connector 20 is connected to the second connector 30, the first connector 20 is located on the inner side of the second connector 30, the charging module 60 may be assembled before the first connector 20 is connected to the second connector 30, thereby improving the working stability of the charging module 60 and reducing the effect of the disassembly of the second connector 30 on the charging module 60.

[0113] The first electrode 61 and the second electrode 62 can also be arranged on the second connector 30, so that the charging module 60 can be assembled with the second connector 30 outside the shell body 12, which is easy to operate. Then, the first connector 20 is connected to the second connector 30 to complete the assembly of the charging module 60, which can improve the convenience of installing the charging module 60.

[0114] like Figure 5 As shown, in some examples, the second electrode 62 is arranged on the inner side of the first annular plate 21, and the second electrode 62 extends along the circumference of the first annular plate 21. Since the first electrode 61 is located at the center of the installation space, the entire second electrode 62 is located at the periphery of the first electrode 61, which can improve the uniformity of the electric field distribution between the first electrode 61 and the second electrode 62, which is beneficial for the particulate matter in the air to fully react with the negative ions generated by corona discharge during the process of entering the air inlet chamber 101, thereby improving the air purification effect.

[0115] Among them, a limiting portion is provided on the first annular plate 21 , and the limiting portion cooperates with the second electrode 62 to limit the second electrode 62 , thereby improving the fixing effect of the second electrode 62 and further improving the working reliability of the charging module 60 .

[0116] In some examples, there may be multiple limiting portions, and the multiple limiting portions are arranged circumferentially on the first annular plate 21, so that the second electrode 62 cooperates with multiple limiting portions at the same time, which can further improve the limiting effect on the second electrode 62, prevent the second electrode 62 from shaking during the operation of the charging module 60, and improve the working stability of the charging module 60.

[0117] like Figure 4 and Figure 7 As shown, in some examples, the number of the limiting parts can be multiple, and the multiple limiting parts include a limiting rib 43 and a first limiting groove 41, the first limiting groove 41 can limit the radial movement of the second electrode 62 along the first annular plate 21, and the first limiting groove 41 can also limit the axial movement of the second electrode 62 toward the first annular plate 21 (such as Figure 4 The front-to-back direction shown) on one side (such as Figure 4 The limiting rib 43 can limit the second electrode 62 from moving to the other side of the axial direction of the first annular plate 21 (such as Figure 4 The second electrode 62 moves along the axial direction of the first annular plate 21, and then the limiting rib 43 and the first limiting groove 41 cooperate with each other.

[0118] The limiting rib 43 can stop the second electrode 62 at the first side (eg, Figure 4 The first limiting groove 41 and the second electrode 62 are on the second side of the first annular plate 21 in the axial direction (as shown in FIG. Figure 4 The front side as shown in the figure is plugged into and matched to stop the second electrode 62 on the second side of the first annular plate 21 in the axial direction, thereby limiting the second electrode 62 in the axial direction of the first annular plate 21 and preventing the second electrode 62 from being disengaged from the first annular plate 21, thereby improving the reliability of the charging module 60.

[0119] In some examples, the first annular plate 21 includes an annular plate body 211 , and the limiting rib 43 is disposed on the inner side of the annular plate body 211 , so that the limiting rib 43 stops the second electrode 62 , thereby improving the limiting effect on the second electrode 62 .

[0120] The first annular plate 21 also includes a limiting baffle 212, which is arranged on the inner side of the annular plate body 211. A first limiting groove 41 is defined between the limiting baffle 212 and the annular plate body 211, so that after the second electrode 62 is plugged into the first limiting groove 41, the axial movement of the second electrode 62 along the first annular plate 21 can be limited. The limiting baffle 212 and the limiting rib 43 are arranged at circumferential intervals on the annular plate body 211, so that in the process of limiting the second electrode 62, the second electrode 62 can be subjected to uniform force, thereby preventing the second electrode 62 from being broken or damaged, and improving the service life of the charging module 60.

[0121] It should be noted that the limiting baffle 212 protrudes toward the inner side of the annular plate body 211, and the protruding limiting baffle 212 can extend backward to form a retaining rib. After the second electrode 62 is plugged into the first limiting groove 41, the retaining rib can abut against the inner circumferential wall surface of the second electrode 62, thereby achieving the radial limitation of the second electrode 62 on the first annular plate 21, which can improve the stability of the second electrode 62, thereby improving the stability of the charging module 60.

[0122] like Figure 7 and Fig. 9 As shown, in some examples, there can be multiple limiting portions, and the multiple limiting portions include two second limiting grooves 42. The second limiting grooves 42 can limit the radial movement of the second electrode 62 along the first annular plate 21, thereby improving the stability of the second electrode 62 and preventing the second electrode 62 from shaking during the operation of the charging module 60, thereby improving the stability of the operation of the charging module 60.

[0123] Among them, the two ends of the second electrode 62 in the circumferential direction of the first annular plate 21 can respectively pass through the two second limiting grooves 42, that is, the second electrode 62 is plugged into the second limiting grooves 42 to achieve the limitation of the second electrode 62, and the two ends of the second electrode 62 extending out of the second limiting grooves 42 respectively have a first anti-detachment part 621, and the size of the first anti-detachment part 621 is larger than the groove width of the second limiting groove 42, which can prevent the two ends of the second electrode 62 from moving radially along the first annular plate 21 to disengage from the second limiting groove 42, thereby improving the limiting effect of the second electrode 62.

[0124] like Fig. 9 As shown, in some examples, a second anti-detachment portion 421 is provided at the notch of the second limiting groove 42, and the second anti-detachment portion 421 can stop the second electrode 62 to achieve the limitation of the second electrode 62, wherein, after the second electrode 62 is plugged into the second limiting groove 42, both ends of the second electrode 62 are clamped with the second anti-detachment portion 421 at the corresponding position of the second limiting groove 42, which can prevent the second electrode 62 from moving axially along the first annular plate 21 to disengage from the second limiting groove 42, and can improve the limiting effect of the second electrode 62.

[0125] like Fig. 9 As shown, in some examples, the second limiting groove 42 has a first groove side wall and a second groove side wall, the first groove side wall and the second groove side wall are arranged opposite to each other, and the second anti-detachment portion 421 is arranged at a position of the first groove side wall close to the groove opening, so that the second anti-detachment portion 421 can stop the second electrode 62 after the second electrode 62 is plugged into the second limiting groove 42, thereby preventing the second electrode 62 from being disengaged from the second limiting groove 42, and improving the limiting effect on the second electrode 62.

[0126] Among them, the side wall of the second groove has a second guide surface 422, the second guide surface 422 extends from the bottom of the second limiting groove 42 to the groove opening, and in the direction from the bottom of the groove to the groove opening, the second guide surface 422 extends obliquely in the direction away from the second anti-detachment portion 421, which can expand the groove opening and can play a guiding role for the second electrode 62, which is beneficial to the plug-in cooperation between the second electrode 62 and the second limiting groove 42.

[0127] It is understandable that the second guide surface 422 can be an inclined surface for easy processing; the second guide surface 422 can also be a curved surface to improve the guiding effect on the second electrode 62 and facilitate the plug-in fit between the second electrode 62 and the second limiting groove 42.

[0128] like Figure 7 As shown, in some examples, the two second limiting grooves 42 are located on both sides of the mounting seat 23 (such as Figure 7 The upper and lower sides shown in the figure can avoid interference between the second electrode 62 and the mounting seat 23, which is beneficial to the installation of the second electrode 62. At the same time, it can play a role in avoiding the protective cover 70, which is beneficial to the installation of the protective cover 70.

The electrostatic dust filter element 52 is arranged in the installation space, so that air can enter the room through the electrostatic dust filter element 52, and the air can fully contact the electrostatic dust filter element 52, thereby improving the filtering effect of the air.

[0130] In some examples, the electrostatic dust removal filter element 52 can be an MSCD washable and consumable-free filter element with a long service life, which can be recycled for up to 10 years and improves the filtration efficiency of the electrostatic dust removal filter element 52; the electrostatic dust removal filter element 52 can also be an IFD filter, an ESP filter or a friction filter, etc., which can improve the filtration efficiency of tiny particles such as dust, pollen, bacteria or viruses.

[0131] like Figure 1 As shown, in some examples, the filter element 50 also includes: a primary filter 53, which is arranged in the air inlet channel 111, and the primary filter 53 is located upstream of the electrostatic dust filter element 52 in the direction of air flow, and can play a role in pre-filtering the air. On the one hand, the primary filter 53 cooperates with the electrostatic dust filter element 52 to improve the filtering effect of the air. On the other hand, it can reduce the working pressure of the electrostatic dust filter element 52, increase the service life of the electrostatic dust filter element 52, and reduce maintenance costs.

[0132] In some examples, the primary filter 53 can capture large particles and coarse particles, wherein the primary filter 53 can be composed of a 200-mesh PET mesh to improve the filtering effect on fine particles in the air, and prevent wind and sand from entering the electrostatic dust filter 52 to damage the electrostatic dust filter 52, thereby increasing the service life of the electrostatic dust filter 52 and reducing maintenance costs.
