Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to a rotatable separation mechanism and an air purifier. Background Technology

[0002] With increasing attention to personal and public environmental health, air purifiers are used in homes, medical facilities, and industrial settings. Their primary function is to remove particulate matter from the air, including various allergens, PM2.5, PM10, toxic gases, and bacteria.

[0003] Currently, most air purifiers on the market require filter replacement by opening the filter compartment door from the bottom or rear side. This method is relatively complex, has high material costs, and is inconvenient to operate. Furthermore, the air outlet direction of most air purifiers is fixed and cannot be adjusted, which leads to inconvenience and a poor user experience, impacting the product's market competitiveness. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotatable separation mechanism that facilitates quick and easy disassembly of the housing for filter replacement. In addition, the user can also adjust the direction of the air outlet as needed using this separation mechanism, which can effectively improve the user experience.

[0005] Another objective of this invention is to provide an air purifier having the aforementioned rotatable separation mechanism.

[0006] The technical solution of this utility model is as follows: a rotatable separation mechanism, including a button, a locking pin, a compression spring, a sub-locking ring, a torsion spring, a female locking ring, a rotating locking seat, and a locking groove on the housing, all mounted in a base bracket. The rotating locking seat is located on one side of the base bracket, and its outer side is connected to the locking groove on the housing. The female locking ring is connected to the rotating locking seat and is located inside the base bracket. The sub-locking ring is located inside the female locking ring and engages with it. A torsion spring is also provided between the sub-locking ring and the female locking ring. The locking pin passes through the center of the base bracket and the rotating locking seat, and a compression spring is provided between the locking pin and the rotating locking seat. The button is located at one end of the locking pin, and the other end of the locking pin is connected to the locking groove on the housing. By pressing the button, the spring force can be used to extend the locking pin out of the rotating seat and fix it to the locking groove on the housing, or to retract the locking pin and separate it from the locking groove on the housing. When the housing is connected to the base bracket, the housing can be rotated manually, and the female locking ring can rotate relative to the female locking ring. Under the action of the torsion spring, the housing can rotate a certain angle relative to the base bracket and be fixed, thereby changing the direction of the air outlet.

[0007] The button, locking pin, compression spring, and rotating bracket together form a press-locking assembly. By pressing the button, the base bracket and the housing can be locked or separated. The sub-locking ring, torsion spring, female locking ring, and rotating bracket together form a rotating assembly. By manually rotating the housing, the housing can be rotated relative to the base bracket, thereby adjusting the direction of the air outlet.

[0008] The button is also provided with a button cover on its outer periphery, and the inner side of the button cover is embedded in the base bracket.

[0009] The base bracket has a central baffle. The side of the central baffle facing the housing is the inner side of the baffle, and the other side is the outer side of the baffle. A first through hole is also provided on the central baffle. The central baffle provides a mounting base for the main components inside the base bracket, and the button and the rotating bracket coaxially pass through the first through hole.

[0010] The button is installed on the outer side of the baffle and passes through the first through hole. The end of the button is also provided with a first limiting block, which is engaged with the inner side of the inner side of the baffle.

[0011] The inner side of the baffle is also provided with an inwardly protruding retaining ring. The diameter of the retaining ring is larger than the diameter of the first through hole. The outer circumference of the retaining ring is provided with several first retaining grooves, and the inner circumference of the retaining ring is provided with torsion spring retaining grooves.

[0012] The sub-clamp ring has an overall ring structure. The inner circumference of the sub-clamp ring is provided with several claws that cooperate with the first clamping groove, and the outer circumference of the sub-clamp ring is provided with external teeth. The claws on the sub-clamp ring are elastic, and each claw of the sub-clamp ring can reciprocate within the first clamping groove using its own plastic elastic force (that is, when the mother clamp ring rotates, the inner teeth of the mother clamp ring squeeze the outer teeth of the sub-clamp ring, causing the claws of the sub-clamp ring to retract and reciprocate within the first clamping groove).

[0013] The inner circumference of the female retaining ring has internal teeth, and the external teeth on the female retaining ring mesh with the internal teeth on the female retaining ring. A second through hole is located in the center of the female retaining ring, and a connecting shaft is located on the rotating base. The connecting shaft passes sequentially through the second through hole on the female retaining ring and the first through hole on the base bracket. A torsion spring is sleeved on the connecting shaft, with one end embedded in a torsion spring slot on the base bracket, and the other end passing through the female retaining ring and fixed to the rotating base. During operation, the rotating base rotates, causing the female retaining ring to reciprocate. The external teeth of the female retaining ring, utilizing their own elasticity, are always meshed with the various levels of internal teeth within the female retaining ring, producing a "clicking" sound. The meshing between the female and female retaining rings, along with the torsion spring providing auxiliary support, allows the housing to be suspended and fixed within 100 degrees to the left and right during manual rotation.

[0014] In the rotating bracket, the end of the connecting shaft is provided with an annular groove, and an E-type retaining spring is provided in the annular groove. The E-type retaining spring is located on one side of the outer side of the baffle, and a flat washer is provided between the E-type retaining spring and the outer side of the baffle. The E-type retaining spring is used to fix the connecting shaft of the rotating bracket to the middle baffle, and the flat washer makes its fixing structure more stable and reliable.

[0015] In the rotating bracket, a sliding through hole is provided on the cylindrical surface of the connecting shaft. A second limiting block is provided in the middle of the locking pin. The second limiting block is embedded in the sliding through hole and slides axially along the sliding through hole. After the end of the locking pin facing the rotating bracket passes through the connecting shaft of the rotating bracket, it is detachably connected to the slot on the housing. A compression spring is sleeved between the locking pin and the connecting shaft.

[0016] The rotating bracket also has a T-shaped bracket on the side facing the housing. Correspondingly, the housing has a T-shaped slot on the slot portion. The T-shaped bracket and the T-shaped slot cooperate with each other. When the locking pin disengages from the slot hole, the T-shaped slot can slide and disengage from the T-shaped bracket by lifting the housing. The slot portion also has a slot hole. When the housing is fixed to the base bracket, the end of the locking pin is embedded in the slot hole.

[0017] This utility model discloses an air purifier having the aforementioned rotatable separation mechanism. The housing is the air purifier body, generally the lower body. Rotatable separation mechanisms are respectively provided on opposite sides of the air purifier, and the two sets of separation mechanisms are symmetrically arranged.

[0018] The aforementioned rotatable separation mechanism simultaneously allows for rotation and separation between the housing and the base support. In use, its principle is as follows: When the housing needs to be rotated to adjust the air outlet direction, the housing is manually rotated. The housing, through the slot, drives the rotating bracket to rotate, which in turn drives the female retaining ring to rotate. The female retaining ring rotates relative to the female retaining ring, and under the action of the torsion spring, the housing can rotate a certain angle relative to the base support and remain fixed, thus changing the air outlet direction. When it is necessary to disassemble and separate the housing and base support, the button is manually pressed, utilizing the elastic force of the compression spring. The button retracts, disengaging the locking pin from the slot hole on the housing. Lifting the housing then causes the T-shaped locking groove in the housing to slide upwards, disengaging from the T-shaped retaining plate on the rotating base, thus separating the housing from the base bracket. To secure the housing to the base bracket, first insert the housing, allowing the T-shaped locking groove to slide along the T-shaped retaining plate until they are fixed. Then press the button. The button pushes the locking pin along the connecting shaft of the rotating base, compressing the spring. The end of the locking pin extends out of the rotating base and inserts into the slot hole in the housing, thus securing the housing to the base bracket. The principle of the press-locking component is similar to that of a ballpoint pen's press mechanism; users can quickly install or detach the housing from the base bracket simply by pressing the button.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This rotatable separation mechanism allows for both rotation and separation between the housing and the base support. This enables quick separation of the housing, facilitating filter replacement or equipment maintenance, and also allows for easy adjustment of the air outlet direction, enhancing user convenience. When applied to air purifiers, it can improve the air purification efficiency of local indoor spaces and also enable the air purifier to function as a small fan, improving the user experience and enhancing the product's market competitiveness.

[0021] This rotatable separation mechanism has a simple structure, is easy to assemble and maintain, and is convenient for daily maintenance and use of equipment. At the same time, its components can be mass-produced and assembled, and its material cost is also low, which makes it easy to promote and apply it on a large scale in air purifiers and even other small household appliances.

Detailed Implementation

[0035] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0036] Example

[0037] This embodiment describes a rotatable separation mechanism and an air purifier.

[0038] like Figure 1 and Figure 8 As shown, the rotatable separation mechanism includes a button 2, a locking pin 3, a compression spring 4, a daughter locking ring 5, a torsion spring 6, a mother locking ring 7, a rotating locking seat 8, and a locking groove 10 on the housing 9, all mounted in the base bracket 1. The rotating locking seat is located on one side of the base bracket, and its outer side is connected to the locking groove on the housing. The mother locking ring is connected to the rotating locking seat and is located inside the base bracket. The daughter locking ring is located inside the mother locking ring and engages with it. A torsion spring is also provided between the daughter locking ring and the mother locking ring. The locking pin passes through the center of the base bracket and the rotating locking seat, and a compression spring is provided between the locking pin and the rotating locking seat. The button is located at one end of the locking pin, and the other end of the locking pin is connected to the locking groove on the housing. By pressing the button, the spring force can be used to extend the locking pin out of the rotating seat and fix it to the locking groove on the housing, or to retract the locking pin and separate it from the locking groove on the housing. When the housing is connected to the base bracket, the housing can be rotated manually, and the female locking ring can rotate relative to the female locking ring. Under the action of the torsion spring, the housing can rotate a certain angle relative to the base bracket and be fixed, thereby changing the direction of the air outlet.

[0039] Among the aforementioned components, the button, locking pin, compression spring, and rotating base constitute a press-lock assembly (such as...). Figure 5As shown), pressing the button can lock or separate the base bracket from the housing; the female retaining ring, torsion spring, female retaining ring, and rotating bracket form a rotating assembly (as shown). Figure 3 or Figure 4 As shown, by manually rotating the housing, the housing can be rotated relative to the base support, thereby adjusting the direction of the air outlet.

[0040] like Figure 1 As shown, a button cover 11 is also provided around the button, and the inner side of the button cover is fitted into the base bracket (e.g. Figure 10 (As shown).

[0041] like Figure 2 and Figure 4 As shown, the base support has a central baffle 12. The side of the central baffle facing the housing is the inner side 12-1, and the other side is the outer side 12-2. A first through hole 12-3 is also provided on the central baffle. The central baffle provides a mounting base for the main components inside the base support, and the button and the rotating bracket coaxially pass through the first through hole.

[0042] like Figure 10 or Figure 11 As shown, the button is mounted on the outer surface of the baffle, and the button passes through the first through hole. The end of the button is also provided with a first limiting block 2-1 (as shown). Figure 5 As shown), the first limiting block is engaged with the inner side of the inner side of the baffle.

[0043] like Figure 2 As shown, the inner side of the baffle is also provided with an inwardly protruding retaining ring 13. The diameter of the retaining ring is larger than the diameter of the first through hole. The outer circumference of the retaining ring is provided with several first retaining grooves 13-1, and the inner circumference of the retaining ring is provided with torsion spring retaining grooves 13-2. The sub-retaining ring is generally in the form of a ring structure. The inner circumference of the sub-retaining ring 5 is provided with several retaining claws 5-1 that cooperate with the first retaining grooves, and the outer circumference of the sub-retaining ring is provided with external teeth 5-2. Among them, the retaining claws on the sub-retaining ring are elastic, and each retaining claw of the sub-retaining ring can reciprocate in the first retaining groove using its own plastic elastic force (that is, when the mother retaining ring rotates, the inner teeth of the mother retaining ring squeeze the outer teeth of the sub-retaining ring, so that the retaining claws of the sub-retaining ring reciprocate in the first retaining groove). Figure 3As shown, the inner circumference of the female retaining ring 7 is provided with internal teeth 7-1, and the external teeth on the female retaining ring mesh with the internal teeth on the female retaining ring; the female retaining ring has a second through hole 7-2 in the middle, and the rotating retaining base 8 has a connecting shaft 8-1, which passes through the second through hole on the female retaining ring and the first through hole on the base bracket in sequence; a torsion spring is sleeved on the connecting shaft, one end of the torsion spring is embedded in the torsion spring slot on the base bracket, and the other end of the torsion spring passes through the female retaining ring and is fixed on the rotating retaining base. During operation, the rotating retaining base rotates, driving the female retaining ring to reciprocate. The external teeth of the female retaining ring always mesh with the internal teeth of the female retaining ring using their own elasticity, thus producing a "clicking" sound. The meshing between the female and female retaining rings and the torsion spring provide auxiliary support, so that when manually rotated, the housing is suspended and fixed at various angles within 100 degrees to the left and right.

[0044] like Figure 4 or Figure 10 As shown, in the rotating bracket, the end of the connecting shaft is also provided with an annular groove 8-2, and an E-type retaining spring 14 is provided in the annular groove. The E-type retaining spring is located on one side of the outer side of the baffle, and a flat washer 15 is provided between the E-type retaining spring and the outer side of the baffle. The E-type retaining spring is used to fix the connecting shaft of the rotating bracket to the middle baffle, and the flat washer makes its fixing structure more stable and reliable. Figure 4 or Figure 5 As shown, in the rotating bracket, a sliding through hole 8-3 is provided on the cylindrical surface of the connecting shaft. A second limiting block 3-1 is provided in the middle of the locking pin. The second limiting block is embedded in the sliding through hole and slides axially along the sliding through hole. After the end of the locking pin facing the rotating bracket passes through the connecting shaft of the rotating bracket, it is detachably connected to the locking groove on the housing. A compression spring is sleeved between the locking pin and the connecting shaft.

[0045] like Figure 8 As shown, the rotating bracket also has a T-shaped bracket 8-4 on the side facing the housing. Correspondingly, the housing has a T-shaped slot 10-1 on the slot portion. The T-shaped bracket and the T-shaped slot cooperate with each other. When the locking pin disengages from the slot hole, the T-shaped slot can slide and disengage from the T-shaped bracket by lifting the housing. The slot portion also has a slot hole 10-2. When the housing is fixed to the base bracket, the end of the locking pin is embedded in the slot hole.

[0046] This embodiment also provides an air purifier having the above-mentioned rotatable separation mechanism, wherein the housing is the air purifier body, generally the lower body; rotatable separation mechanisms are respectively provided on opposite sides of the air purifier, and the two sets of separation mechanisms are symmetrically arranged.

[0047] The aforementioned rotatable separation mechanism simultaneously allows for rotation and separation between the housing and the base support. In use, its principle is as follows: Figure 6 and Figure 7As shown, when it is necessary to rotate the housing to adjust the direction of the air outlet, the housing is rotated manually. The housing drives the rotating bracket to rotate via the slot, and the rotating bracket drives the female retaining ring to rotate. The female retaining ring rotates relative to the female retaining ring, and simultaneously, under the action of the torsion spring, the housing can rotate a certain angle relative to the base bracket and be fixed, thus changing the direction of the air outlet. Figure 8 and Figure 10 As shown, when it is necessary to disassemble the housing and base bracket, manually pressing the button utilizes the elastic force of the compression spring to retract the locking pin and disengage it from the locking slot on the housing. Then, lifting the housing causes the T-shaped locking slot in the housing to slide upwards and disengage from the T-shaped locking seat on the rotating bracket, thus separating the housing from the base bracket. Figure 9 and Figure 11 As shown, when it is necessary to fix the housing and the base bracket, first insert the housing, allowing the T-shaped slot to slide along the T-shaped bracket until they are fixed. Then press the button. The button pushes the locking pin to slide along the connecting shaft of the rotating bracket, compressing the spring. The end of the locking pin extends out of the rotating bracket and inserts into the slot hole in the slot section, thus achieving the fixed installation between the housing and the base bracket. The principle of the press-locking component is similar to that of a ballpoint pen's press mechanism; the user can quickly install or detach the housing and the base bracket simply by pressing the button.

[0048] As described above, the present invention can be well implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made in accordance with the content of the present invention are covered by the scope of protection claimed by the claims of the present invention.
