[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0039] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0040] To address the technical problem of the single air outlet direction in existing air purifiers, this application provides an air purifier housing structure and an air purifier 1 that enables multi-angle adjustment of the air outlet direction of the air purifier 1.

[0041] like Figures 1 to 7 As shown, in a first aspect, embodiments of this application provide an air purifier housing structure, including a support assembly 10 and a housing 20. The support assembly 10 includes a base 11 and a support rod 12, with the support rod 12 vertically mounted on the base 11. The housing 20 has an air inlet 21 and an air outlet 22, and the housing 20 rotates around a horizontal axis of rotation in coordination with the support rod 12.

[0042] The technical solutions provided in this application have the following advantages compared with the prior art:

[0043] The air purifier housing structure provided in this application embodiment includes a support assembly 10 and a housing 20. The support assembly 10 includes a base 11 and a support rod 12. The housing 20 has an air inlet 21 and an air outlet 22. The housing 20 is rotatably mounted on the support rod 12. The tilt angle of the housing 20 can be adjusted as needed to change the direction of the air outlet 22, so that the air outlet 22 faces upward or horizontally, to meet the user's needs for different air outlet directions.

[0044] In this embodiment, the support component 10 includes a base 11 and a support rod 12. The base 11 serves as the bottom support component of the air purifier 1 and can be circular, square, or other shapes. The support rod 12 is mounted on the base 11 and is used to support the outer casing 20.

[0045] The outer casing 20 serves as a protective shell for the air purifier 1, and its shape is generally cylindrical or square. The outer casing 20 has an air inlet 21 and an air outlet 22. The air inlet 21 is usually located on the side wall of the outer casing 20 and has a densely packed mesh. The air outlet 22 is usually located on the top of the outer casing 20 and has an air outlet grille. When the outer casing 20... Figure 3 When the air outlet 22 shown is horizontal, it can be used as a fan to blow air.

[0046] The base 11, support rod 12, and outer shell 20 can be made of metal (such as stainless steel, aluminum alloy, etc.), or engineering plastic, carbon fiber, etc., and users can choose the appropriate materials according to their needs.

[0047] The outer casing 20 and the support rod 12 rotate together to achieve pitch adjustment of the air outlet direction. Optionally, a motor or other rotary drive mechanism can be installed on the support rod 12 to drive the outer casing 20 to rotate, thereby achieving automatic adjustment of the air outlet direction. Alternatively, a rotating shaft and a limiting clip can be installed between the outer casing 20 and the support rod 12 to achieve manual adjustment of the air outlet direction.

[0048] Depending on the requirements, the maximum pitch angle range of the housing 20 can be 90° up or down or other angles, which can be set according to the user's needs.

[0049] Please see Figure 1 and Figure 2 In some possible embodiments, the support rod 12 is rotatably engaged with the base 11, and the support assembly 10 also includes a rotating mechanism 13 disposed on the base 11, the rotating mechanism 13 being used to drive the support rod 12 to rotate about a vertical axis.

[0050] In this embodiment, a rotating mechanism 13 is provided inside the base 11. The rotating mechanism 13 can drive the support rod 12 to rotate around a vertical axis, thereby realizing the left and right tilting of the outer shell 20. When the outer shell 20 is in the position... Figure 3 When the air outlet 22 is horizontal, it can be used as a fan to blow air. In conjunction with the rotating mechanism 13, it can swing left and right to increase the air blowing range.

[0051] When the base 11 is a solid structure, the rotating mechanism 13 can be located outside the base 11; when the base 11 is a hollow structure, the rotating mechanism 13 can be located inside the base 11.

[0052] Optionally, the rotating mechanism 13 includes a motor, the output shaft of which outputs rotational power and drives the support rod 12 to rotate through gear meshing, chain drive, belt drive, or other means.

[0053] Please see Figure 2Furthermore, the support rod 12 can be a hollow tube with a wire-passing channel 121 inside. The wire-passing channel 121 is used to pass through the power supply wire 50, which is used to connect with the rotating mechanism 13 to realize the circuit conduction. Optionally, the support rod 12 can be a circular tube, a square tube, etc.

[0054] Please see Figure 1 and Figure 3 In some possible embodiments, the outer shell 20 is a hollow cylindrical component, the air inlet 21 is opened on the side wall of the outer shell 20, and the air outlet 22 is opened on one of the shaft ends of the outer shell 20. During the rotation of the outer shell 20, the outer shell 20 has at least a first posture with the air outlet 22 vertically upward, a second posture with the air outlet 22 obliquely upward, and a third posture with the air outlet 22 horizontal.

[0055] In this embodiment, the side wall of the outer casing 20 is provided with a dense array of air inlets 21, which are mesh-like and have a large air intake area. An air outlet 22 is provided on the top of the outer casing 20, and an air outlet grille is provided at the air outlet 22. Users can adjust the pitch angle of the outer casing 20 as needed to achieve airflow at different angles.

[0056] Figure 1 The middle arrow indicates the direction of airflow. Under the action of the internal air outlet component 40, air enters the outer casing 20 through the side air inlet 21, passes through the filter component 30, and is blown out from the air outlet 22.

[0057] Please see Figures 4 to 7 In some possible embodiments, the top end of the support rod 12 is formed with a hinge portion 122, and the inside of the housing 20 is provided with a connecting seat 24, which is rotatably engaged with the hinge portion 122. The side wall of the housing 20 is provided with a relief groove 23, and during the rotation of the housing 20, the upper part of the support rod 12 is accommodated in the relief groove 23.

[0058] The connecting seat 24 is located inside the housing 20. The connecting seat 24 can be integrally formed with the housing 20, or it can be detachably connected by fasteners such as screws. The connecting seat 24 is rotatably engaged with the hinge part 122. When in the first posture, the housing 20 and the support rod 12 are coaxial. In order to avoid interference between the housing 20 and the support rod 12 when rotating, the housing 20 is provided with a relief groove 23. During rotation, the upper part of the support rod 12 is accommodated in the relief groove 23.

[0059] Please see Figures 4 to 7In some possible embodiments, the hinge portion 122 is cylindrical, and the end of the hinge portion 122 is provided with a mounting groove 1221. The connecting seat 24 is provided with a receiving groove 241, which is used to accommodate the hinge portion 122. The support assembly 10 also includes a positioning mechanism 14 disposed in the mounting groove 1221. During the rotation of the housing 20, the positioning mechanism 14 can limit the connecting seat 24.

[0060] The positioning mechanism 14 can be an electric telescopic rod, etc., which can limit the outer shell 20 when extended and release the limit when retracted. Alternatively, the positioning mechanism 14 can also be a locking block, limit pin, etc. with elastic clamping force, which can automatically lock and limit the outer shell 20 after it rotates to a certain angle.

[0061] Please see Figures 4 to 7 In some possible embodiments, the positioning mechanism 14 includes a positioning plate 141, a ball bearing 142, and an elastic element 143. The positioning plate 141 is disposed in the receiving groove 241 and is engaged with the connecting seat 24 via a snap-fit ​​ear 1412. The positioning plate 141 can rotate together with the connecting seat 24, and the positioning plate 141 has a plurality of positioning holes 1411 along the rotation direction of the connecting seat 24. The ball bearing 142 is disposed in the mounting groove 1221 and abuts against the positioning plate 141. The elastic element 143 is disposed in the mounting groove 1221 along the rotation axis of the hinge portion 122, and the elastic element 143 is configured with a preload force to press the ball bearing 142 against the positioning holes 1411.

[0062] The positioning mechanism 14 includes a positioning plate 141, a ball bearing 142, and an elastic element 143. During assembly, the spring and ball bearing 142 are first placed into the mounting groove 1221, with the spring compressed. Then, the positioning plate 141 is placed over the opening of the mounting groove 1221. Finally, the assembled positioning mechanism 14 is placed into the receiving groove 241 of the connecting seat 24, so that the snap-fit ​​ears 1412 of the positioning plate 141 and the snap-fit ​​grooves on the connecting seat 24 engage and fit, limiting the positioning plate 141 so that it can rotate with the connecting seat 24. When the positioning plate 141 rotates with the connecting seat 24, once the ball bearing 142 aligns with the positioning hole 1411, it can engage and limit the connection seat 24. One or more balls bearing 142 and elastic elements 143 can be provided as needed. After assembly, the power cord is then connected along... Figure 2 The path shown is used to insert the wires into the support pipe.

[0063] Please see Figure 5 and Figure 6 Furthermore, mounting grooves 1221 are respectively provided at both ends of the hinge portion 122, and two positioning mechanisms 14 are provided corresponding to the mounting grooves 1221, which helps to stabilize the force on the connecting seat 24 and prevent malfunctions such as rotation jamming and excessive wear.

[0064] Please see Figure 5 , Figure 6 and Figure 7 Furthermore, a connecting bolt 15 passes between the hinge portion 122 and the connecting seat 24. A fixing nut 16 is threaded onto the connecting bolt 15. The fixing nut 16 and the nut of the connecting bolt 15 form a clamping space for accommodating the hinge portion 122 and the connecting seat 24. The connecting bolt 15 and the fixing nut 16 coaxially connect the hinge portion 122 and the connecting seat 24 into a single unit. The clamping force between the connecting bolt 15 and the fixing nut 16 should not be too large to ensure that the connecting seat 24 can rotate smoothly.

[0065] Please see Figures 1 to 4 Secondly, this application provides an air purifier 1, including the air purifier housing structure, filter assembly 30, and air outlet assembly 40 as described in any of the above embodiments. The filter assembly 30 is disposed inside the housing 20 and corresponds to the air inlet 21; the air outlet assembly 40 includes a fan disposed inside the housing 20 and a motor for driving the fan to rotate.

[0066] The air purifier 1 provided in this application has a tilt adjustment function, allowing for adjustment of the airflow direction as needed. The filter assembly 30 can be a single-layer or multi-layer filter, capable of filtering dust, pet hair, pollen, etc., and also adsorbing odors, formaldehyde, etc. When the air outlet assembly 40 is working, it generates airflow, allowing outside air to enter the outer casing 20, be filtered and adsorbed by the filter assembly 30, and then blown out from the air outlet 22, maintaining the cleanliness of indoor air.
