[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figure 1 and Figure 2 The air purifier 10 in one embodiment of the present invention can at least achieve the convenience of installation. Specifically, the air purifier 10 includes a purification body 100 and an air duct assembly 200 , and a vent 110 is formed on the purification body 100 .

[0038] Please also read Figure 3 The air duct assembly 200 includes a mounting member 210 and an air duct member 220. The mounting member 210 is formed with a connecting cavity 211. The connecting cavity 211 runs through the two surfaces of the mounting member 210 and respectively forms a first opening 212 and a second opening 213. The side of the mounting member 210 formed with the first opening 212 is installed at the vent 110 of the purification body 100, so that the connecting cavity 211 can be connected to the vent 110 through the first opening 212. The air duct member 220 is formed with an air supply channel 221, and the air supply channel 221 runs through both ends of the air duct member 220 and respectively forms a first air outlet 222 and a second air outlet 223. One end of the air duct member 220 formed with the first air outlet 222 is rotatably arranged on a side of the mounting member 210 formed with the second opening 213, so that the air supply channel 221 is connected to the connecting cavity 211, and the opening direction of the second air outlet 223 is set at a non-straight angle to the opening direction of the first opening 212.

[0039] When the air purifier 10 and the air duct assembly 200 are in use, one end of the air duct member 220 of the air duct assembly 200 having the first air outlet 222 is rotatably arranged on the side of the mounting member 210 having the second opening 213, so that the air supply channel 221 is connected to the connecting cavity 211. The side of the mounting member 210 having the first opening 212 is mounted at the vent 110 of the purification body 100, so that the connecting cavity 211 can be connected to the vent 110 through the first opening 212, thereby realizing the communication between the air supply channel 221 and the vent 110 of the purification body 100. By setting the mounting member 210, the installation of the air duct member 220 on the purification body 100 can be facilitated, thereby realizing the rotation of the air duct member 220 relative to the purification body 100, and avoiding the need to change the structure of the purification body 100 due to the setting of the air duct member 220. During the installation of the air purifier 10, the opening direction of the second air outlet 223 can be adjusted to a suitable position by rotating the air duct member 220, so as to facilitate the connection between the second air outlet 223 and other channels, avoid the distortion of the air duct connected to the second air outlet 223, and ensure the stability of air flow. Through the above-mentioned air purifier 10, the convenience of installation of the air purifier 10 can be effectively improved, and the position of the purification body 100 can be adjusted due to the need to adjust the direction of the second air outlet 223.

[0040] In this embodiment, the opening direction of the second air outlet 223 is set at a right angle to the opening direction of the first opening 212, and the second air outlet 223 can be adjusted to different directions on a plane by rotating the air duct member 220. In other embodiments, the opening direction of the second air outlet 223 can also be set at an acute angle or an obtuse angle to the opening direction of the first opening 212.

[0041] In one embodiment, at least two vents 110 are formed on the purification body 100, at least one of the vents 110 is an air inlet, and at least another of the vents 110 is an air outlet. There are two air duct components 200, and the two air duct components 200 are respectively arranged at the air inlet and the air outlet. In the process of purifying air, the purification body 100 can take in air from the air inlet and discharge it from the air outlet after purification. By respectively arranging the air duct components 200 at the air inlet and the air outlet, it is possible to further facilitate the connection between the air inlet and the air outlet of the purification body 100 and other components, and further improve the convenience of installing the air purifier 10.

[0042] In another embodiment, the air duct assembly 200 may be provided only at the air inlet to improve the stability of the air inlet communicating with other components, or the air duct assembly 200 may be provided only at the air outlet to improve the stability of the air outlet communicating with other components.

[0043] In one embodiment, the side of the mounting member 210 having the first opening 212 is mounted on the vent 110 of the purification body 100 by screws. In other embodiments, the mounting member 210 can also be mounted on the vent 110 of the purification body 100 by welding, clamping, gluing, etc.

[0044] See also Figure 2 and Figure 3 In one embodiment, the air duct member 220 includes an air duct portion 224 and a rotating portion 225. The air duct portion 224 is formed with the air supply channel 221. The first air outlet 222 and the second air outlet 223 are respectively formed at opposite ends of the air duct portion 224. The rotating portion 225 is disposed on one end of the air duct portion 224 where the first air outlet 222 is formed. A rotating hole 2251 is provided on the rotating portion 225. The mounting member 210 is provided with a mounting hole 214, which is communicated with the rotating hole 2251. The rotating portion 225 is rotatable relative to the mounting member 210. The rotating portion 225 is rotated relative to the mounting member 210 to facilitate the adjustment of the opening direction of the second air outlet 223 of the air duct member 220. After the second air outlet 223 is adjusted to a proper position, it is further connected to the mounting hole 214 through the rotating hole 2251, so that the connecting screw passes through the rotating hole 2251 and is inserted into the mounting hole 214, so as to fix the rotating part 225 on the mounting member 210, and further fix the air duct part 224 on the mounting member 210.

[0045] In this embodiment, the rotating hole 2251 is an annular hole, and the axis of the rotating hole 2251 is the rotating axis of the air duct member 220 relative to the mounting member 210. Since the axis of the rotating hole 2251 is the same as the axis of the rotating member of the air duct member 220, the mounting hole 214 can be stably connected to the rotating hole 2251 during the rotation process, so that the rotating part 225 can be installed on the mounting member 210.

[0046] In other embodiments, the rotating hole 2251 may be a circular hole, and the mounting hole 214 may be an annular hole. Different rotating holes 2251 are arranged around the rotating axis of the air duct member 220, and different rotating holes 2251 can all be connected to the mounting hole 214. In addition, when the rotating portion 225 rotates relative to the mounting member 210, different rotating holes 2251 can all be effectively connected to the mounting hole 214.

[0047] See also Figure 3 and Figure 4In one embodiment, the rotating portion 225 includes a first matching portion 2252 and a second matching portion 2253. The first matching portion 2252 and the second matching portion 2253 are both annular structures, and the first matching portion 2252 is disposed in the area surrounded by the inner circle of the second matching portion 2253. The first matching portion 2252 and the second matching portion 2253 are spaced apart to form the rotating hole 2251. The first matching portion 2252 is disposed on the air duct portion 224. The first matching portion 2252 and the second matching portion 2253 are spaced apart to facilitate the formation of the rotating hole 2251.

[0048] In this embodiment, the rotating portion 225 further includes a connecting portion 2254, one end of which is connected to the first matching portion 2252, and the other end of which is connected to the second matching portion 2253. The connecting portion 2254 is provided to facilitate the connection between the first matching portion 2252 and the second matching portion 2253, thereby facilitating the first matching portion 2252 and the second matching portion 2253 to form the rotating hole 2251 more stably, thereby preventing the first matching portion 2252 and the second matching portion 2253 from moving relative to each other, thereby affecting the stability of the connection between the rotating hole 2251 and the mounting hole 214.

[0049] Specifically, the connecting portion 2254 is arranged on the side of the first matching portion 2252 facing away from the mounting member 210, and a connecting groove 2256 is provided on the side of the connecting portion 2254 facing the mounting member 210, and the connecting groove 2256 is connected to the rotating hole 2251. When in use, when one end of the connecting screw is passed through the rotating hole 2251 and inserted into the mounting hole 214, the connecting screw is not tightened at this time. The rotating portion 225 is rotated relative to the mounting member 210 to adjust the second air outlet 223 to a suitable position. During the adjustment process, since the connecting screw is inserted into the rotating hole 2251, the connecting screw is prevented from interfering with the rotation of the rotating portion 225. By providing the connecting groove 2256, a certain amount of movable space can be reserved for the connecting screw. In other embodiments, the connecting groove 2256 may also be omitted, and the connecting screws may be inserted into the rotating hole 2251 and the mounting hole 214 after the position of the second air outlet 223 is adjusted to fix the air duct member 220 on the mounting member 210.

[0050] In one embodiment, one end of the connecting portion 2254 is integrally formed on the first matching portion 2252, and the other end of the connecting portion 2254 is integrally formed on the second matching portion 2253. This can effectively improve the stability of the connecting portion 2254 connecting the first matching portion 2252 and the second matching portion 2253, thereby ensuring the stability of the rotation hole 2251. In other embodiments, one end of the connecting portion 2254 can also be connected to the first matching portion 2252 by welding, gluing, clamping, screw connection, etc. The other end of the connecting portion 2254 can also be connected to the second matching portion 2253 by welding, gluing, clamping, screw connection, etc.

[0051] In one embodiment, there may be at least two connecting parts 2254, and at least two connecting parts 2254 are arranged at intervals around the rotation axis of the air duct member 220. By providing at least two connecting parts 2254, the stability of the connection between the first matching part 2252 and the second matching part 2253 can be improved. In this embodiment, there are four connecting parts 2254, and the four connecting parts 2254 are evenly spaced around the rotation axis of the air duct member 220. In other embodiments, the number of connecting parts 2254 can also be other numbers, as long as the connection between the first matching part 2252 and the second matching part 2253 can be easily achieved.

[0052] See also Figure 3 and Figure 5 In one embodiment, there are a plurality of mounting holes 214, which are arranged at intervals around the rotation axis of the air duct member 220, and each mounting hole 214 can be connected to the rotation hole 2251. By providing a plurality of mounting holes 214, it is convenient for the connecting screw to pass through the rotation hole 2251 and further penetrate into the mounting hole 214, thereby realizing the installation of the connecting screw, so as to realize the installation of the rotating part 225 on the mounting member 210.

[0053] In this embodiment, the mounting member 210 is provided with a plurality of support portions 215, and the plurality of support portions 215 are arranged at intervals around the rotation axis of the air duct member 220, and each support portion 215 is provided with a corresponding mounting hole 214. By providing the support portion 215 on the mounting member 210, it is convenient to open the mounting hole 214, and then it is convenient for the connecting screw to be stably fixed on the mounting member 210. In other embodiments, the support portion 215 can also be omitted, and the mounting hole 214 can be directly opened on the mounting member 210.

[0054] See also Figure 3 and Figure 5In one embodiment, the mounting member 210 is provided with at least eight mounting holes 214 arranged at intervals, so that the rotating portion 225 and the mounting member 210 can be installed and connected by at least eight connecting screws. Specifically, at least eight mounting holes 214 are evenly arranged around the rotation axis of the air duct member 220. In this embodiment, there are four connecting portions 2254, and the four connecting portions 2254 are evenly arranged around the rotation axis of the air duct member 220. When the air duct member 220 is rotated, after the position is adjusted, if the connecting portion 2254 covers the mounting hole 214, at this time, at least four mounting holes 214 are not covered. This ensures that the second air outlet 223 can be fixed in any direction by at least four connecting screws.

[0055] In this embodiment, the number of the support portions 215 is consistent with the number of the mounting holes 214 , so as to facilitate the opening of the mounting holes 214 .

[0056] In one embodiment, a guide groove 216 is formed on one side of the mounting member 210 where the second opening 213 is formed. The guide groove 216 is an annular groove. The second opening 213 is located in the area surrounded by the inner circle of the guide groove 216. The rotating portion 225 can be inserted into the guide groove 216 and can rotate in the guide groove 216. The support portion 215 is disposed in the guide groove 216. By forming the guide groove 216 on the mounting member 210, the stability of the rotating portion 225 relative to the mounting member 210 can be further improved, and the position of the rotating portion 225 relative to the mounting member 210 can be prevented from being offset during the rotation process. In other embodiments, the guide groove 216 can also be omitted.

[0057] See also Figure 2 and Figure 3 In one embodiment, the duct member 220 includes at least two components, each of which is formed with a component groove, and different components are connected to each other so that different component grooves can be connected to each other to form an air supply channel 221. By arranging the duct member 220 into different components, it is easy to process the duct member 220, reduce the difficulty of processing the duct member 220, and form the air supply channel 221 by combining.

[0058] In other embodiments, the air duct member 220 may also be divided into other number of components along the axial direction of the air supply channel 221 , and different components are connected to each other so that different component grooves can be connected to form the air supply channel 221 .

[0059] In this embodiment, for example, the air duct member 220 includes a first component part 226 and a second component part 227, a first component groove 2262 is formed on the first component part 226, and a second component groove 2272 is formed on the second component part 227, and the first component part 226 and the second component part 227 are connected to each other so that the first component groove 2262 and the second component groove 2272 are connected to form the air supply channel 221.

[0060] Specifically, the air channel portion 224 can be divided into two parts, and the two parts can respectively become parts of the first component 226 and the second component 227. The rotating portion 225 can be divided into two parts, and the two parts can respectively become other parts of the first component 226 and the second component 227.

[0061] Optionally, the air duct member 220 is divided into a first component 226 and a second component 227 along the axial direction of the air supply channel 221. In other embodiments, the air duct member 220 can also be divided into two parts along other directions to improve the convenience of processing.

[0062] In one embodiment, the first component 226 is provided with a first clamping portion 2264, and the second component 227 is provided with a second clamping portion 2274, and the second clamping portion 2274 can be clamped on the first clamping portion. The clamping of the first clamping portion 2264 and the second clamping portion 2274 facilitates the installation of the first component 226 and the second component 227, and facilitates the combination to form the air duct member 220.

[0063] In other embodiments, the first component 226 and the second component 227 may be connected by welding, gluing, screw connection, etc., as long as the air supply channel 221 can be formed. Alternatively, the air duct member 220 may also be an integrally formed structure, which can improve the stability of the air duct member 220 structure.

[0064] In one embodiment, an elevator includes a car and the air purifier 10 in any of the above embodiments, wherein an air vent is formed on the car; the air purifier 10 is disposed on the car, and the second air vent 223 can be communicated with the air vent.

[0065] In the elevator, the air purifier 10 is arranged on the elevator car, and according to the position of the air vent on the car, the air duct member 220 is rotated so that the second air vent 223 of the air duct member 220 can be connected to the air vent in correspondence. Since other components for realizing the operation of the car need to be installed on the car, the space for installing the air purifier 10 on the car is very limited. Further, since the opening direction of the second air vent 223 of the air duct member 220 is arranged at a non-straight angle with the opening direction of the first opening 212 of the mounting member 210, the opening direction of the second air vent 223 can be adjusted to a suitable position by rotating the air duct member 220, so that the second air vent 223 can be connected to the air vent in correspondence, reducing the difficulty of connecting the second air vent 223 to the air vent. In the process of preventing the second air vent 223 from being connected to the air vent, the air duct connecting the second air vent 223 and the air vent will be twisted, resulting in obstruction of air flow, thereby affecting the efficiency of the use of the air purifier 10.

[0066] In one embodiment, at least two vents are formed on the car, and at least two vents 110 are formed on the purification body 100, at least one of the vents 110 is an air inlet, and at least another of the vents 110 is an air outlet. There are two air duct components 200, and the two air duct components 200 are respectively arranged at the air inlet and the air outlet. The second air vent 223 of one of the air duct components 200 is connected to a corresponding air vent, so that the purified air is blown into the car through the air vent to purify the air in the car. The second air vent 223 of the other air duct component 200 can be connected to the other air vent.

[0067] In use, the purification body 100 extracts the air in the car through an air duct assembly 200, and the air enters the purification body 100 through the air inlet of the purification body 100.
