[0002] Air-conditioned clothing consists of two small fans installed on the left and right sides of a person's upper garment or trousers. These fans draw outdoor air into the clothing and absorb heat from the body's surface through the vaporization of sweat, thus cooling the body and providing a refreshing and comfortable feeling. However, current air-conditioned clothing and fans are fixed together, making disassembly and assembly cumbersome and inconvenient. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this utility model is to provide an air conditioning fan, which can be easily disassembled and assembled by a locking ring that is detachably connected to the fan body, making it easy to remove the fan body and facilitate subsequent maintenance; at the same time, the locking mechanism ensures a strong locking force between the locking ring and the fan body after assembly, making it difficult to detach.

[0005] (II) Technical Solution

[0006] The solution adopted by this utility model to solve the above-mentioned technical problems is an air-conditioning clothing fan, including a fan body and a locking structure that can lock the fan body onto the air-conditioning clothing; the locking structure includes a locking ring detachably connected to the fan body, and at least one locking member movably connected to the locking ring and capable of passing through the locking ring and engaging with the fan body for locking.

[0007] By adopting the above solution, the locking ring that is detachably connected to the fan body allows for easy assembly and disassembly of the two, making it convenient to remove the fan body and facilitating subsequent maintenance. At the same time, the locking mechanism ensures a strong locking force between the assembled locking ring and the fan body, making it difficult for them to come loose.

[0008] In some embodiments, the locking member includes a locking portion protruding from one side near the fan body, and correspondingly, a locking engagement portion is provided on the outer wall of the fan body to engage with the locking portion for locking; and the locking ring is provided with an opening through which the locking portion passes.

[0009] Specifically, the opening enables locking and unlocking between the locking part and the locking mating part, resulting in a stable structure and convenient operation.

[0010] By adopting the above solution, the locking part and the locking mating part cooperate to achieve locking between the locking member and the fan body, thereby achieving locking between the locking ring and the fan body.

[0011] In some embodiments, the locking portion includes a first mating surface extending in a longitudinal direction and a second mating surface extending obliquely in an axial direction, wherein the first mating surface and the second mating surface intersect at one end near the locking mating portion; correspondingly, the locking mating portion includes a first abutting surface abutting against the first mating surface and a second abutting surface abutting against the second mating surface.

[0012] Specifically, after the locking part engages with the locking mating part, the first mating surface abuts against the first abutting surface, and the second mating surface abuts against the second abutting surface, which can restrict the movement of the locking part in the axial direction, thereby achieving a firm lock between the locking part and the locking mating part.

[0013] In some embodiments, the locking member is rotatably connected to the locking ring via a rotating shaft, and the two ends of the locking member at the rotatable connection point with the rotating shaft are respectively formed with a locking end and a free end; and the locking end and the free end are rotatable around the rotating shaft; wherein the locking end is provided with the locking portion.

[0014] Specifically, the locking end has three locking parts on the side facing the fan body, and they are arranged at equal intervals along the axial direction.

[0015] In some embodiments, the rotating shaft is fixed to the locking ring, and the locking ring has openings on both sides of the rotating shaft to ensure normal rotation of the locking end and the free end.

[0016] In some embodiments, the free end and the locking end are connected as a single unit along the outer periphery of the locking ring, and are capable of rotating about the rotation axis.

[0017] Specifically, when the locking member rotates around the rotating shaft, when its locking end moves towards the direction of the fan body, and the locking part on the locking end engages with the locking engagement part on the fan body, the locking end can be locked on the fan body, thereby achieving a fixed connection between the locking ring and the fan body; and, when the locking end moves towards the direction of the fan body, the free end moves synchronously away from the housing; similarly, when the free end is pressed and moved towards the direction of the fan body, the locking end will be driven to move synchronously away from the fan body, so that the locking part disengages from the locking engagement part on the fan body, thereby unlocking the locking end and the fan body, and thus unlocking the locking ring and the fan body; thus, the fan body and the locking ring can be separated.

[0018] In some embodiments, a mounting groove is provided near the free end of the locking ring, and an elastic element is provided in the mounting groove. One end of the elastic element abuts against the mounting groove, and the other end abuts against the free end. Furthermore, the elastic element can provide the free end with a force that always tends to move outward.

[0019] In some embodiments, the retaining ring is symmetrically provided with two sets of locking members, each set including two locking members, and the retaining ring is provided with two symmetrically arranged elastic members, each elastic member cooperating with the two locking members; wherein, the free ends of the two locking members are arranged close to each other, the locking end of any one locking member is located at the end of its free end away from the other locking member, and the free ends of both locking members are connected to the elastic members; the free end includes a connecting portion connected to the elastic member; and the connecting portion is formed on the side of the free end facing the fan body, and the free ends of both locking members are provided with the connecting portion, fastening into the elastic member to achieve the connection of the locking members on the elastic member, so as not to disengage.

[0020] Specifically, after the locking member rotates to engage with the locking part of the fan body, the elastic member applies an outward thrust to the free end, ensuring that the locking part is firmly engaged within the locking part and will not disengage. Pressing the free end causes the locking end to move away from the fan body and disengage from the locking part, thus unlocking the device. Releasing the hand causes the elastic member to apply an outward thrust to the free end, causing the locking end to move towards the fan body.

[0021] In some embodiments, the fan body includes a housing, fan blades disposed within the housing, a motor that powers the fan blades, a PCB board electrically connected to the motor, and a DC male connector electrically connected to the PCB board.

[0022] Specifically, the DC male connector is made of copper and fixed on the PCB board, which has good conductivity, tight insertion and removal, and is not easy to fall off. In addition, the fan blades are thinner, which can increase the fan speed and air volume, effectively reduce the load on the motor and extend the service life of the motor. At the same time, reducing the load can also reduce power consumption and extend the usage time of the external drive battery. The motor is a brushless motor, which has a long life, high efficiency, and small size.

[0023] In some embodiments, the housing includes a rear cover with an open front end and a front cover that is threadedly connected to the rear cover; wherein the locking ring is disposed on the rear cover, and the locking member can pass through the locking ring and engage with the rear cover to lock.

[0024] Using the above solution, the front cover and the rear cover are disassembled and assembled by a screw, which facilitates the subsequent cleaning of dirt and dust on the fan blades.

[0025] In some embodiments, the front cover includes an annular wall that can extend into the rear cover body, and a front grille connected to the front end of the annular wall for closing the fan blades; the outer wall of the annular wall is provided with external threads, and the inner wall of the rear cover body is provided with internal threads that engage with the external threads; and, at the junction of the annular wall and the front grille, an annular protrusion is formed protruding outward along the circumferential direction, the annular protrusion extending beyond the outer wall of the locking ring.

[0026] Specifically, the annular protrusion makes it easier to assemble and disassemble the retaining ring and the fan body; at the same time, it also makes it easier to assemble and disassemble the front cover and the rear cover.

[0027] In some embodiments, the rear end of the rear cover is recessed inward to form a receiving groove for accommodating the motor, the PCB board and the DC male connector. The bottom wall of the receiving groove has a through hole for the drive end of the motor to pass through and cooperate with the fan blade. The top of the receiving groove is detachably connected to a motor rear cover, and the motor rear cover is made of silicone material, which can effectively play a waterproof role.

[0028] Specifically, the side wall of the rear cover is provided with an opening that communicates with the receiving groove to expose the DC male connector for connecting an external drive battery; and the motor rear cover covers the DC male connector to ensure a good seal and waterproof performance between the motor rear cover and the DC male connector.

[0029] In some embodiments, a groove is provided on the bottom wall of the receiving tank near the end of the fan blade. The groove is filled with lubricating grease, which can lubricate the motor bearing, extend the motor life, and at the same time drive away water molecules from entering the motor and damaging it.

[0059] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0060] like Figures 1-11 As shown, this utility model provides an air-conditioning garment fan, including a fan body 100 and a locking structure 200 capable of locking the fan body 100 onto an air-conditioning garment. The locking structure 200 includes a locking ring 201 detachably connected to the outside of the fan body 100, and a locking member 202 movably connected to the locking ring 201 and capable of passing through the locking ring 201 to engage with and lock the fan body 100. With this solution, the locking ring 201, detachably connected to the fan body 100, allows for easy assembly and disassembly, facilitating the removal of the fan body and subsequent maintenance. Simultaneously, the locking member 202 ensures a strong locking force between the assembled locking ring 201 and the fan body 100, preventing easy detachment.

[0061] In some embodiments, the locking member 202 includes a locking portion 2021 protruding from one side near the fan body 100. Correspondingly, a locking engagement portion 101 is provided on the outer wall of the fan body 100 to engage with the locking portion 2021 for locking. Furthermore, the locking ring 201 has an opening 2011 through which the locking portion 2021 passes. Specifically, the opening 2011 enables locking and unlocking between the locking portion 2021 and the locking engagement portion 101, resulting in a stable structure and convenient operation. Using the above solution, the engagement of the locking portion 2021 and the locking engagement portion 101 achieves locking between the locking member 202 and the fan body 100, thereby securing the locking ring 201 and the fan body 100. In some embodiments, the locking portion 2021 includes a first mating surface 2021a extending in the longitudinal direction and a second mating surface 2021b extending obliquely in the axial direction, wherein the first mating surface 2021a and the second mating surface 2021b intersect at one end near the locking mating portion 101; correspondingly, the locking mating portion 101 includes a first abutting surface 1011 abutting against the first mating surface 2021a and a second abutting surface 1012 abutting against the second mating surface 2021b. Specifically, after the locking portion 2021 is engaged with the locking mating portion 101, the first mating surface 2021a and the first abutting surface 1011 abut against each other, and the second mating surface 2021b and the second abutting surface 1012 abut against each other, which can restrict the movement of the locking portion 2021 in the axial direction, thereby achieving a firm lock between the locking portion 2021 and the locking mating portion 101.

[0062] In some embodiments, the locking member 202 is rotatably connected to the locking ring 201 via a rotating shaft 203, and the two ends of the locking member 202 at the rotatable connection point with the rotating shaft 203 are respectively formed with a locking end 2022 and a free end 2023; and the locking end 2022 and the free end 2023 are rotatable around the rotating shaft 203; wherein the locking end 2022 is provided with a locking portion 2021. Specifically, the locking end 2022 has three locking portions 2021 on the side facing the fan body 100, and they are arranged at equal intervals along the axial direction. In some embodiments, the rotating shaft 203 is fixed to the locking ring 201, and the locking ring 201 is provided with openings 2011 on both sides of the rotating shaft 203 to ensure the normal rotation of the locking end 2022 and the free end 2023. In some embodiments, the free end 2023 and the locking end 2022 are connected as a single unit along the outer periphery of the locking ring 201, and are capable of rotating around the rotation axis 203. Specifically, when the locking member 202 rotates around the rotation axis 203, when its locking end 2022 moves toward the fan body 100, until the locking part 2021 on the locking end 2022 engages with the locking engagement part 101 on the fan body 100, the locking end 2022 can be locked on the fan body 100, thereby achieving a fixed connection between the locking ring 201 and the fan body 100; and, when the locking end 2022 moves toward the fan body 100, the free end 2023 moves synchronously. Moving the free end 2023 away from the housing, similarly, pressing the free end 2023 to move it closer to the fan body 100 will cause the locking end 2022 to move synchronously away from the fan body 100, thereby disengaging the locking part 2021 from the locking engagement part 101 on the fan body 100, thus unlocking the locking end 2022 and the fan body 100, and unlocking the locking ring 201 and the fan body 100; thus, the fan body 100 and the locking ring 201 can be separated. In some embodiments, the locking ring 201 is provided with a mounting groove 2012 near the free end 2023, and an elastic member 204 is provided in the mounting groove 2012. One end of the elastic member 204 abuts against the mounting groove 2012, and the other end abuts against the free end 2023. Furthermore, the elastic member 204 can provide the free end 2023 with a force that always tends to move outward.In some embodiments, the retaining ring is symmetrically provided with two sets of locking members 202, each set of locking members 202 including two locking members 202, and the retaining ring is provided with two symmetrically arranged elastic members 204, each elastic member 204 cooperating with two locking members 202; wherein, the free ends 2023 of the two locking members 202 are arranged close to each other, and the locking end 2022 of any locking member 202 is located at the end of its free end 2023 away from the other locking member 202, and the two locking members 202... The free ends 2023 of the two locking members 202 are all connected to the elastic member 204. The free ends 2023 include connecting portions 2023a that connect to the elastic member 204. The connecting portions 2023a are formed on the side of the free ends 2023 facing the fan body 100, and the free ends 2023 of the two locking members 202 are provided with the connecting portions 2023a, which are fastened in the elastic member 204 to realize the connection of the locking members 202 on the elastic member 204 and prevent them from coming off. Specifically, after the locking member 202 rotates until its locking end 2022's locking part 2021 engages with the locking engagement part 101 of the fan body 100, the elastic member 204 applies an outward pushing force to the free end 2023, so that the locking part 2021 can be firmly engaged in the locking engagement part 101 and will not disengage; then, after pressing the free end 2023, the locking end 2022 will move away from the fan body 100 and cause the locking part 2021 to disengage from the locking engagement part 101, thereby unlocking; after releasing the hand, the elastic member 204 can apply an outward pushing force to the free end 2023, so that the locking end 2022 tends to move towards the fan body 100.

[0063] In some embodiments, the fan body 100 includes a housing 102, fan blades 103 disposed within the housing 102, a motor 104 powering the fan blades 103, a PCB board 105 electrically connected to the motor 104, and a DC male connector 106 electrically connected to the PCB board 105. Specifically, the DC male connector 106 is a copper DC male connector, fixed on the PCB board 105, which has good conductivity, tight insertion and removal, and is not easy to fall off; furthermore, the fan blades 103 are thinner, which can increase the fan speed and air volume, effectively reduce the load on the motor 104 and extend the service life of the motor 104. At the same time, reducing the load can also reduce power consumption and extend the usage time of the external drive battery; the motor 104 is a brushless motor 104, which has a long life, high efficiency, and small size.

[0064] In some embodiments, the housing 102 includes a rear cover 1021 with an open front end and a front cover 1022 threadedly connected to the rear cover 1021; wherein, a locking ring 201 is fitted onto the rear cover 1021, and the locking member 202 can pass through the locking ring 201 to engage and lock with the rear cover 1021. With this design, the front cover 1022 and the rear cover 1021 are disassembled and reassembled by a screw mechanism, facilitating subsequent cleaning of dirt and dust on the fan blades 103. In some embodiments, the front cover 1022 includes an annular wall 1022a that can extend into the rear cover 1021, and a front grille 1022b connected to the front end of the annular wall 1022a for closing the fan blades 103; the outer wall of the annular wall 1022a is provided with an external thread 1022c, and the inner wall of the rear cover 1021 is provided with an internal thread 1021a that engages with the external thread 1022c; and, at the junction of the annular wall 1022a and the front grille 1022b, an annular protrusion 1022d is formed by protruding outward in the circumferential direction, and the annular protrusion 1022d extends beyond the outer wall of the locking ring 201. Specifically, the annular protrusion 1022d makes it easier to assemble and disassemble the locking ring and the fan body 100; at the same time, it also makes it easier to assemble and disassemble the front cover 1022 and the rear cover 1021.

[0065] In some embodiments, the rear end of the rear cover 1021 is recessed inward to form a receiving groove 1021b for accommodating the motor 104, the PCB board 105, and the DC male connector 106. The bottom wall of the receiving groove 1021b has a through hole 1021c for the drive end of the motor 104 to pass through and cooperate with the fan blade 103. The top end of the receiving groove 1021b is detachably connected to a motor rear cover 1023, which is made of silicone material and can effectively provide waterproofing. Specifically, the side wall of the rear cover 1021 has an opening communicating with the receiving groove 1021b to expose the DC male connector 106 for connecting an external drive battery; and the motor rear cover 1023 covers the AC connector to ensure a tight seal between the motor rear cover 1023 and the DC male connector 106, providing excellent waterproofing. In some embodiments, a groove 1021d is provided on the bottom wall of the receiving groove 1021b near the end of the fan blade 103. The groove 1021d is filled with lubricating grease, which can lubricate the bearing of the motor 104, extend the life of the motor 104, and at the same time drive away water molecules from entering the motor 104 and damaging the motor 104.
