Description

Technical Field

[0001] This application relates to the field of air purification equipment, and in particular to a rotatable air purifier. Background Technology

[0002] Traditional air purifiers have a fixed air outlet angle, which cannot be adjusted to suit different usage scenarios, resulting in inconvenience. To address this, some air purifiers with adjustable air outlet angles have appeared on the market. These purifiers typically have their main body rotatably connected to a base, allowing the angle to be adjusted by rotating relative to the base. The adjusted position is then secured by a friction damping structure or spring-loaded points between the purifier and the base. While these air purifiers can adjust the air outlet angle, they have the following drawbacks and limitations:

[0003] After the air purifier body is adjusted to the desired angle, its position is fixed by the friction damping structure or spring protrusions between it and the base. However, when the weight of the air purifier body itself or the adjustment angle is large, the resistance provided by the friction damping structure and spring protrusions is relatively limited, resulting in an unstable fixation and affecting the reliability of the product.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0024] The rotatable air purifier of this application has its main body connected to a base via a rotating assembly.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] Traditional air purifiers have a fixed air outlet angle, making them unsuitable for diverse usage scenarios and causing inconvenience for users. To address this issue, a series of air purifiers with adjustable air outlet angles have emerged on the market. These new air purifiers generally feature a design where the purifier body is rotatably connected to the base, allowing users to adjust the air outlet angle by rotating the purifier body to meet different usage needs. To achieve stable positioning after adjustment, these products typically incorporate a friction damping structure or a spring-loaded protrusion structure between the purifier body and the base. The spring-loaded protrusion structure consists of a set of springs and protrusions on the purifier body, with a positioning groove on the base. The springs push the protrusions into the positioning groove, fixing their positions. However, while these air purifiers with angle adjustment functions have solved the problem of fixed air outlet angles to some extent, they still have the following drawbacks: when the purifier body is heavy or the user chooses an extreme usage angle, the limited resistance provided by the friction damping structure or spring-loaded protrusion structure for fixing often makes it difficult to ensure stability after adjustment. This lack of secure fixing can not only lead to unexpected changes in the angle of the air outlet during use, but may also affect the overall performance and lifespan of the air purifier, thereby reducing the reliability of the product.

[0036] To address the aforementioned technical problems, this embodiment provides a rotatable air purifier. (See also...) Figures 1 to 5 As shown, Figure 1 This is a top view of the rotatable air purifier in the embodiments of this application. Figure 2 This is a front view of the rotatable air purifier in the embodiments of this application. Figure 3 This is an exploded view of the rotatable air purifier in the embodiments of this application. Figure 4 It is the connecting component in Figure 1 Cross-sectional perspective view of section A. Figure 5 It is the connecting component in Figure 2 A three-dimensional sectional view of section B.

[0037] The rotatable air purifier in this embodiment includes: a base 1, a purifier body 2, a rotating shaft 3, and a fixing cover 4.

[0038] like Figure 3 As shown, the base 1 is provided with a shaft hole 11, and at least two slots 12 are provided inside the shaft hole 11. The slots 12 are evenly arranged along the circumferential direction of the shaft hole 11.

[0039] The rotating shaft 3 and the fixed cover 4 are components of the rotating assembly, such as... Figure 4 As shown, one end of the rotating shaft 3 is connected to the purifier body 2 and is fixed relative to the purifier body 2 in the circumferential direction, as... Figure 5As shown, the other end of the rotating shaft 3 is rotatably disposed in the shaft hole 11 and is provided with at least two locking points 31 that are adapted to the slots 12. The locking points 31 have elastic deformation capability so as to engage and release with the slots 12 during the rotation of the rotating shaft 3. Release refers to the process of the locking point 31 rotating from one slot 12 to another slot 12. The fixed cover 4 is fixedly connected to the base 1 and seals one end of the shaft hole 11. The other end of the rotating shaft 3 is located between the base 1 and the fixed cover 4 in the axial direction. When the purifier body 2 rotates relative to the base 1 to the use angle, each locking point 31 engages with one slot 12.

[0040] It is understandable that the number and distribution range of the slots 12 can be set according to the preset usage angle of the purifier body 2. For example, when the usage angle range of the purifier body 2 is large, the distribution range of the slots 12 also becomes more adaptable. The higher the precision required for the angle adjustment of the purifier body 2, the more slots 12 there are, and the smaller the spacing between the slots 12.

[0041] For example, each slot 12 is evenly arranged in the circumferential direction inside the shaft hole 11 and fills the inside of the shaft hole 11. The spacing between the slots 12 is less than the width of the slot 12, thereby improving the accuracy of angle adjustment.

[0042] It is understandable that the number of checkpoints 31 can be set according to the resistance required for the purifier body 2 to be stably placed at the extreme angle; that is, the greater the required resistance, the more checkpoints 31 there are.

[0043] For example, each locking point 31 is evenly arranged in the circumferential direction of the rotating shaft 3, and there are 3 to 4 of them, so as to improve the stability of the purifier body 2 after the angle is adjusted.

[0044] The purifier body 2 of the rotatable air purifier described above is connected to the base 1 via a rotating assembly. This assembly allows the purifier body 2 to rotate around the base 1 to adjust its operating angle and ensures stability after adjustment. Specifically, one end of the rotating shaft 3 of the rotating assembly is connected to the purifier body 2 and is fixed relative to it in the circumferential direction, allowing the rotating shaft 3 to rotate when the purifier body 2 rotates. The other end of the shaft 3 is rotatably disposed within a shaft hole 11 and has a locking point 31 with elastic deformation capability. This allows the shaft 3 to engage and disengage with the slot 12 of the base 1 during rotation. Simultaneously, the other end of the shaft 3 is axially limited between the base 1 and the fixed cover 4 to prevent disengagement. This configuration ensures that when the purifier body 2 rotates relative to the base 1 to the operating angle, each locking point 31 of the shaft 3 engages with a slot 12, and the resistance between the locking points 31 and the slots 12 fixes the position of the purifier body 2. Compared to existing air purifiers that fix the operating angle using friction damping structures or spring protrusions, the rotatable air purifier with the above technical solution improves the stability of the purifier body 2 after adjusting the operating angle through the interlocking action of at least two sets of locking points 31 and locking slots 12. This avoids angle changes caused by wear of the friction damping structure or failure of the spring protrusions, thereby improving the safety of product use. At the same time, the interlocking fixing method of locking points 31 and locking slots 12 reduces the failure rate caused by improper angle adjustment or fixing failure, thereby enhancing the reliability and durability of the product. Equally important, users can easily adjust the operating angle of the purifier body 2 according to actual needs and obtain stable use results through the reliable fixing of locking points 31 and locking slots 12, thereby improving the user experience and satisfaction.

[0045] For example, see Figure 5 As shown, in order to improve the smoothness of the angle adjustment operation, the slots 12 are smoothly transitioned and the edges of the locking points 31 are chamfered. These designs not only reduce the frictional resistance of the locking points 31 when switching between the slots 12, but also improve their fitting accuracy and lifespan.

[0046] In one embodiment where one end of the aforementioned rotating shaft 3 is connected to the purifier body 2 and is relatively fixed to the purifier body 2 in the circumferential direction, see [reference needed]. Figure 3 and Figure 4As shown, the purifier body 2 includes a housing 21, which has a fixing hole 22. The rotating assembly also includes a fixing shaft 5, which is sleeved inside the fixing hole 22 and fixed relative to the fixing hole 22 in the circumferential direction. One end of the fixing shaft 5 has a first shoulder 51, which is used to limit the fixing shaft 5 to the inside of the housing 21 in the axial direction, preventing the fixing shaft 5 from moving towards the base 1. The other end of the fixing shaft 5 is fixedly connected to the rotating shaft 3, such as by screws. One end of the rotating shaft 3 is limited to the outside of the housing 21 in the axial direction.

[0047] For example, see Figure 3 As shown, the cross-sectional shape of the fixing hole 22 and the fixing shaft 5 is the same and is not circular, such as square or partially circular. Thus, when the fixing shaft 5 is sleeved inside the fixing hole 22, it can be fixed relative to the fixing hole 22 in the circumferential direction.

[0048] For example, the fixing hole 22 and the fixing shaft 5 can also be fixed relative to each other in the circumferential direction by key connection or tight fit.

[0049] For example, see Figure 4 As shown, the upper limit of one end of the rotating shaft 3 in the axial direction on the outside of the housing 21 can be achieved in the following way: one end of the rotating shaft 3 is provided with a sleeve hole 32, and the other end of the fixed shaft 5 is sleeved on the inside of the sleeve hole 32; one end of the rotating shaft 3 in the axial direction is limited to the outside of the housing 21 by the end face of the sleeve hole 32, so that the rotating shaft 3 cannot move towards the base 1.

[0050] In another embodiment (not shown), where one end of the aforementioned rotating shaft 3 is connected to the purifier body 2 and is relatively fixed to the purifier body 2 in the circumferential direction, the rotating shaft 3 and the purifier body 2 are fixedly connected by bolts or clips.

[0051] See Figure 4 and Figure 5 As shown, the aforementioned rotating shaft 3 is provided with locking points 31 that have elastic deformation capability, which can be achieved in the following way: The other end of the rotating shaft 3 is provided with an annular convex wall 33. The convex wall 33 has several notches, and ribs 34 are formed between the notches. The number of ribs 34 is the same as the number of locking points 31. The ribs 34 have the ability to elastically bend towards the center of the convex wall 33. It can be understood that this elastic bending capability is achieved by using a material with elastic deformation capability for the convex wall 33, such as plastic or metal that can deform to a certain extent. The ribs 34 have locking points 31 on their outer sides. Thus, when the locking points 31 switch between the locking slots 12, the protruding part between the locking slots 12 pushes the locking points 31, causing the ribs 34 to bend inward until the locking points 31 are aligned with the locking slot 12 corresponding to the target angle, and then reset, engaging with the locking slot 12.

[0052] The aforementioned rotating shaft 3 is provided with a locking point 31 that has elastic deformation capability, which can also be achieved in the following way (not shown in the figure): the locking point 31 is bonded or embedded on the outside of the rotating shaft 3, and the locking point 31 is a material such as rubber or spring sheet that can be squeezed and reset.

[0053] To limit the range of usability angle of the purifier body 2, and to axially limit the rotation shaft 3, please refer to... Figure 3 and Figure 5 As shown, the base 1 has a limiting groove 13 extending circumferentially on the end face of the shaft hole 11, and the other end of the rotating shaft 3 has a limiting protrusion 35 extending outward. The limiting protrusion 35 is rotatably disposed in the limiting groove 13. During the rotation of the rotating shaft 3, the limiting protrusion 35 moves within the limiting groove 13 and is limited by the groove wall of the limiting groove 13, thus limiting the rotation range of the rotating shaft 3. At the same time, the limiting protrusion 35 abuts against the bottom of the limiting groove 13, preventing the rotating shaft 3 from moving towards the purifier body 2, thereby achieving axial limitation of the rotating shaft 3.

[0054] To prevent the rotating shaft 3 from disengaging from the shaft hole 11 in the direction of the purifier body 2, see [reference needed]. Figure 4 As shown, the shaft hole 11 is provided with a shoulder 14, and the rotating shaft 3 is provided with a second shoulder 36, which limits the shaft to the side of the shoulder 14 away from the base 1.

[0055] To improve the stability of the purifier body 2 on the base 1 and to make the force on the purifier body 2 more even after angle adjustment, please refer to... Figure 1 and Figure 2 As shown, the base 1 is provided with two support arms 15, and the support arms 15 are provided with shaft holes 11. The shaft holes 11 of the two support arms 15 are arranged coaxially. The purifier body 2 is located between the two support arms 15, and each of the opposite sides of the purifier body 2 is connected to the two support arms 15 through a set of rotating components.

[0056] For example, see Figure 3 and Figure 4 As shown, the support arm 15 is connected to a cover 16 by a snap fastener, and the cover 16 seals the internal structure.

[0057] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
