In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] Reference below Figure 1-Figure 12 The air treatment device 100 according to an embodiment of the present invention is described. The air treatment device 100 can be applied to a cabinet unit. The air treatment device 100 can purify and humidify indoor air to better meet the actual needs of users.

[0037] According to the air treatment device 100 of the embodiment of the present invention, Figure 1 and Figure 3 As shown, it includes: a panel 1, a face frame 2 and a Hall switch 3.

[0038] Specifically, Figure 1 and Figure 2 As shown, the face frame 2 is detachably connected to the panel 1, and the user can remove the panel 1 from the face frame 2 as needed. For example, a water tank and a filter net can also be provided in the air treatment device 100, and the panel 1 can be removed from the face frame 2 when the user needs to add water to the water tank, or needs to replace or clean the filter net.

[0039] like Figure 3 and Figure 4 As shown, the Hall switch 3 is arranged on the face frame 2, one of the face frame 2 and the Hall switch 3 is provided with a stop protrusion 21, and the other of the face frame 2 and the Hall switch 3 is provided with a limit groove 31 that cooperates with the stop protrusion 21, and the distance between at least one pair of opposite side walls on the Hall switch 3 and the limit groove 31 is not equal.

[0040] It can be understood that the face frame 2 may be provided with a stop protrusion 21, and the Hall switch 3 may be provided with a limit groove 31 that cooperates with the stop protrusion 21; or, the Hall switch 3 may be provided with a stop protrusion 21, and the face frame 2 may be provided with a limit groove 31 that cooperates with the stop protrusion 21.

[0041] Specifically, when the Hall switch 3 is loaded into the face frame 2 in the forward direction, the stop protrusion 21 can avoid the other parts of the Hall switch 3 with the help of the limit groove 31, so that the correct installation of the stop protrusion 21 can be completed; when the Hall switch 3 is loaded into the face frame 2 in the reverse direction, since the distances between at least one pair of opposite side walls of the Hall switch 3 and the limit groove 31 are not equal, the stop protrusion 21 cannot cooperate with the limit groove 31, resulting in interference between the stop protrusion 21 and the Hall switch 3. At this time, the assembler can find the problem in time and adjust the Hall switch 3 to the correct installation angle, so that the Hall switch 3 has an anti-fool effect, thereby avoiding incorrect installation of the Hall switch 3, and then improving the assembly efficiency of the Hall switch 3 and reducing the cost of assembly and rework.

[0042] For example, in Figure 3 and Figure 4 In the illustrated embodiment, a stop protrusion 21 is provided on the face frame 2, and a limiting groove 31 cooperating with the stop protrusion 21 is provided on the Hall switch 3. The distances between the left and right walls of the Hall switch 3 and the limiting groove 31 are not equal.

[0043] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the air treatment device 100 may also be provided with a fan 4 and a first magnetic member 51 (see Figure 2 ), the first magnetic member 51 can be arranged on the panel 1, and the fan 4 can be arranged on the face frame 2. When the panel 1 is mounted on the face frame 2, the Hall switch 3 is located within the magnetic range of the first magnetic member 51. When the panel 1 is removed, the fan 4 stops running, thereby ensuring the safety of the air treatment device 100 and further ensuring the safety of the user; when the panel 1 is closed, the fan 4 can be started and stopped normally, ensuring the normal operation of the air treatment device 100.

[0044] The Hall switch 3 can be connected to the circuit where the fan 4 is located. Of course, the Hall switch 3 can also be connected to the controller of the air treatment device 100. Therefore, when the panel 1 is installed on the face frame 2, the Hall switch 3 is closed by the magnetic field of the magnetic part, and the fan 4 can start and stop normally; when the panel 1 is removed from the face frame 2, the magnetic part is away from the Hall switch 3, and the Hall switch 3 is not affected by the magnetic field of the magnetic part, and the Hall switch 3 is disconnected, so that the fan 4 stops working.

[0045] According to the air treatment device 100 of the embodiment of the present invention, a stop protrusion 21 is provided on one of the face frame 2 and the Hall switch 3, and a limit groove 31 is provided on the other of the face frame 2 and the Hall switch 3 to cooperate with the stop protrusion 21, and the distance between at least one pair of opposite side walls of the Hall switch 3 and the limit groove 31 is not equal. When the Hall switch 3 is forwardly loaded into the face frame 2, the stop protrusion 21 can avoid other parts of the Hall switch 3 with the help of the limit groove 31, so that the correct installation of the stop protrusion 21 can be completed; when the Hall switch 3 is reversely loaded into the face frame 2, the stop protrusion 21 cannot cooperate with the limit groove 31, thereby causing interference between the stop protrusion 21 and the Hall switch 3, and at this time, the assembler can find the problem in time and adjust the Hall switch 3 to the correct installation angle. In this way, the foolproof effect of the Hall switch 3 can be improved, thereby improving the assembly efficiency of the Hall switch 3 and reducing the cost of assembly and rework.

[0046] According to some embodiments of the present invention, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the face frame 2 is provided with a receiving groove 22, the Hall switch 3 is arranged in the receiving groove 22, and a stop protrusion 21 is provided on the bottom wall of the receiving groove 22. The receiving groove 22 has a protective and limiting function for the Hall switch 3, which can prevent the components inside the air treatment device 100 from colliding with the Hall switch 3, thereby improving the reliability of the Hall switch 3. In addition, the stop protrusion 21 is arranged on the bottom wall of the receiving groove 22, which can reduce the difficulty of manufacturing the stop protrusion 21 and reduce the manufacturing cost of the stop protrusion 21. For example, the stop protrusion 21 and the receiving groove 22 can be integrally formed.

[0047] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 8 As shown, one side of the stop protrusion 21 extends to one of the side walls of the receiving groove 22, and the limiting groove 31 extends to the corresponding side wall of the Hall switch 3. Thus, the manufacturing difficulty of the stop protrusion 21 can be reduced, the complexity of the structure of the stop protrusion 21 can be simplified, the manufacturing difficulty of the stop protrusion 21 can be reduced, the production efficiency of the stop protrusion 21 can be improved, and the production cost of the stop protrusion 21 can be further reduced. For example, the left side of the stop protrusion 21 can extend to the left side wall of the receiving groove 22, and the limiting groove 31 extends to the left side wall of the Hall switch 3.

[0048] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 8As shown, the adjacent two sides of the stop protrusion 21 extend to the adjacent two side walls of the receiving groove 22, and the corresponding two sides of the limit groove 31 extend to the corresponding two adjacent side walls of the Hall switch 3. In this way, the connection area between the stop protrusion 21 and the receiving groove 22 can be increased, thereby increasing the connection strength between the stop protrusion 21 and the receiving groove 22, thereby ensuring the reliability of the stop protrusion 21. For example, Figure 4 and Figure 8 In the illustrated embodiment, the upper side and left side of the stop protrusion 21 extend to the upper side wall and left side wall of the accommodating groove 22 respectively, and the corresponding two sides of the limiting groove 31 extend to the upper side wall and left side wall of the Hall switch 3 respectively.

[0049] Furthermore, if Figure 5 , Figure 8 and Fig. 9 As shown, along the installation direction of the Hall switch 3, the limit groove 31 passes through the Hall switch 3. Thus, the complexity of the structure of the limit groove 31 can be simplified, the difficulty of manufacturing the limit groove 31 can be reduced, the production efficiency of the limit groove 31 can be improved, and the production cost of the limit groove 31 can be reduced. Specifically, when manufacturing the limit groove 31, only a turning tool is used to process along the installation direction of the Hall switch 3 to complete the processing of the limit groove 31.

[0050] Preferably, if Figure 4 , Figure 8 and Fig. 9 As shown, a hand-removal groove 32 is provided on the side wall of the Hall switch 3, and the side of the hand-removal groove 32 away from the face frame 2 is open. By providing the hand-removal groove 32 on the side of the Hall switch 3 away from the face frame 2, it is convenient for technicians to take the Hall switch 3 out of the receiving groove 22, thereby reducing the difficulty of disassembling and repairing the Hall switch 3 and improving the efficiency of repairing and replacing the Hall switch 3.

[0051] Furthermore, if Fig. 9 and Fig.10 As shown, the two ends of the finger-taking groove 32 extend to the two side walls of the Hall switch 3 adjacent to the limit groove 31 (refer to Fig.11 ). Thus, the complexity of the structure of the hand-taking groove 32 can be simplified, the manufacturing difficulty of the hand-taking groove 32 can be reduced, the production efficiency of the hand-taking groove 32 can be improved, and the production cost of the hand-taking groove 32 can be reduced. Specifically, when manufacturing the hand-taking groove 32, only a turning tool is used along the pre-extended direction of the hand-taking groove 32 to complete the processing of the hand-taking groove 32.

[0052] In some embodiments of the present invention, Figure 8 and Fig. 9As shown, the hand-removing groove 32 and the limiting groove 31 are located on the same side of the Hall switch 3 and are connected. Therefore, when processing the hand-removing groove 32 and the limiting groove 31, the processing of the hand-removing groove 32 and the limiting groove 31 can be completed on the same side of the Hall switch 3, so that there is no need to adjust the processing surface of the Hall switch 3, thereby saving processing time and improving the production efficiency of the Hall switch 3. For example, Figure 8 In the illustrated embodiment, the finger removal slot 32 and the limit slot 31 are both located on the left side of the Hall switch 3 and are connected.

[0053] According to some embodiments of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, the face frame 2 has a fixing plate 23, the panel 1 covers the fixing plate 23, and the Hall switch 3 is arranged on a side of the fixing plate 23 away from the panel 1 (such as Figure 3 As a result, when the panel 1 is removed from the face frame 2, the fixing plate 23 can shield the Hall switch 3, preventing the Hall switch 3 from being exposed within the user's visible range, thereby improving the aesthetics of the air treatment device 100.

[0054] Furthermore, if Figure 1 and Figure 3 As shown, there are two fixing plates 23, which are respectively arranged on both sides of the width direction of the face frame 2, and the Hall switch 3 is arranged on the side of one of the fixing plates 23 away from the panel 1. Therefore, the Hall switch 3 can be arranged on the side of one of the fixing plates 23 away from the panel 1 as needed to meet the needs of different models of air treatment devices 100. For example, the Hall switch 3 can be arranged on the side of the fixing plate 23 on the right side of the face frame 2 in the width direction away from the panel 1.

[0055] According to some embodiments of the present invention, Figure 1 , Figure 2 , Figure 4 and Fig.12 As shown, the side of the fixing plate 23 away from the panel 1 (such as Figure 3 The right side of the figure) is provided with a second magnetic member 52 (refer to Figure 3 ), the first magnetic member 51 and the second magnetic member 52 attract each other. Thus, the panel 1 and the face frame 2 can be connected by the attraction between the first magnetic member 51 and the second magnetic member 52, and it is convenient for the user to install and remove the panel 1. In addition, the first magnetic member 51 is arranged on the side of the panel 1 facing the face frame 2, and the second magnetic member 52 is arranged on the side of the fixing plate 23 facing away from the panel 1. The panel 1 can shield the first magnetic member 51, and can shield the second magnetic member 52 while covering the fixing plate 23.

[0056] When the air treatment device 100 is viewed from the front, that is, when the face frame 2 is viewed from the panel 1, the first magnetic member 51 and the second magnetic member 52 are not visible, thereby ensuring the aesthetics of the air treatment device 100. In addition, since the second magnetic member 52 is disposed on the side of the fixing plate 23 that is away from the panel 1, even when the panel 1 is removed, the second magnetic member 52 is not visible when the air treatment device 100 is viewed from the front, thereby further increasing the aesthetics of the air treatment device 100.

[0057] In some embodiments of the present invention, Figure 3 , Figure 4 and Figure 6 As shown, the face frame 2 is provided with a first stopper 24, which is located on a side of the fixing plate 23 away from the panel 1 and is spaced apart from the fixing plate 23, and the second magnetic member 52 is limited between the fixing plate 23 and the first stopper 24. In this way, the second magnetic member 52 can be fixed and limited, the reliability of the second magnetic member 52 fixing can be improved, and the second magnetic member 52 can be prevented from moving in the direction toward the panel 1 and in the direction away from the panel 1.

[0058] Furthermore, if Figure 3 , Figure 4 and Figure 7 As shown, the face frame 2 is provided with a second stopper 25, which defines a receiving space for the second magnetic member 52 together with the first stopper 24 and the fixing plate 23, and the second stopper 25 has a first guide slope, which is inclined in a direction away from the fixing plate 23 in the direction from the second stopper 25 to the first stopper 24. The first guide slope guides the installation of the second magnetic member 52, facilitates the assembly of the second magnetic member 52, and thus improves the assembly efficiency.

[0059] In some embodiments of the present invention, Figure 1 and Figure 8 As shown, the Hall switch 3 further includes a connecting column 33. When the Hall switch 3 is installed in place, the connecting column 33 is connected in series with the circuit where the fan 4 is located, or the connecting column 33 is connected to the controller of the air treatment device 100. Thus, the electrical connection between the Hall switch 3 and the circuit where the fan 4 is located can be achieved, or the connection between the Hall switch 3 and the controller of the air treatment device 100 can be achieved.
