[0001] This utility model relates to the technical field of fans, and in particular to fans for air-conditioned clothing. [Background technology]

[0002] Air-conditioned clothing is a cool and comfortable product that has two small fans attached to the left and right waistbands of a shirt or pants, drawing outdoor air into the clothing and absorbing heat from the surface of the body through the evaporative cooling of sweat.However, existing air-conditioned clothing and the fans are fixed together, making it difficult to remove and very inconvenient to put on and take off the fans. Summary of the Invention [Problem to be solved by the invention]

[0003] The technical problem to be solved by this utility model is to provide a fan for air-conditioned clothing. A locking snap ring removably connected to the fan body allows for easy attachment and detachment of the two, facilitating removal of the fan body and facilitating subsequent maintenance. At the same time, the installation of a locking member ensures that the fastening force between the locking snap ring and the fan body after assembly is very strong, making them less likely to come apart. [Means for solving the problem]

[0004] The solution adopted by this utility model to solve the above technical problems is as follows: A fan for air-conditioned clothing, comprising: a fan body; and a locking mechanism capable of locking the fan body to the air-conditioned clothing, the locking mechanism including a locking snap ring detachably connected to the outside of the fan body; and at least one locking member movably connected to the locking snap ring and capable of passing through the locking snap ring to engage with and lock the fan body.

[0005] With the above solution, the locking snap ring is removably connected to the fan body, making it easy to attach and detach the two, facilitating removal of the fan body and facilitating subsequent maintenance. At the same time, the installation of the locking member ensures that the fastening force between the locking snap ring and the fan body after assembly is very strong, making them less likely to come apart.

[0006] In some embodiments, the locking member includes a locking portion protruding from and adjacent to the fan body, and a corresponding locking engagement portion is provided on the outer wall of the fan body to engage with the locking portion for locking, and the locking snap ring has an opening through which the locking portion passes.

[0007] Specifically, the opening can realize the locking and unlocking between the locking part and the locking fitting part, which is stable in structure and convenient in operation.

[0008] By using the above solution, the locking member and the fan body can be locked by the engagement of the locking portion with the locking fitting portion, thereby realizing the locking and fixing between the locking snap ring and the fan body.

[0009] In some embodiments, the locking portion includes a first mating surface extending along the longitudinal direction and a second mating surface extending at an angle along the axial direction, and the first mating surface and the second mating surface intersect at an end proximate to the locking portion, and correspondingly, the locking portion includes a first abutment surface abutting the first mating surface and a second abutment surface abutting the second mating surface.

[0010] Specifically, after the locking portion engages with the locking fitting portion, the first fitting surface abuts against the first abutment surface, and the second fitting surface abuts against the second abutment surface, which can restrict the axial movement of the locking portion, thereby achieving a strong lock between the locking portion and the locking fitting portion.

[0011] In some embodiments, the locking member is rotatably connected to the locking snap ring via a rotating shaft, and the locking member has a locking end and a free end at both ends of a rotational connection with the rotating shaft, and the locking end and the free end can rotate around the rotating shaft, and the locking portion is installed on the locking end.

[0012] Specifically, the locking end has three locking portions arranged toward the fan body, and they are arranged at equal intervals along the axial direction.

[0013] In some embodiments, the rotating shaft is fixed to the locking snap ring, and the locking snap ring has openings on both sides of the rotating shaft to ensure normal rotation between the locking end and the free end.

[0014] In some embodiments, the free end and the locking end are integrally connected along the circumferential direction of the locking snap ring and are rotatable about the rotation axis.

[0015] Specifically, when the locking member rotates around the rotation axis, its locking end moves toward the fan body until its locking portion engages with the locking fitting of the fan body, thereby locking the locking end to the fan body, thereby realizing a fixed connection between the locking snap ring and the fan body. When the locking end moves toward the fan body, the free end moves synchronously in a direction away from the housing. Similarly, when the free end is pressed and moved toward the fan body, the locking end is driven to move synchronously in a direction away from the fan body, thereby disengaging the locking portion from the locking fitting of the fan body and realizing the lock release between the locking end and the fan body. This releases the lock between the locking snap ring and the fan body, allowing the fan body and the locking snap ring to be separated.

[0016] In some embodiments, the locking snap ring has a mounting groove disposed near the free end, and an elastic member disposed within the mounting groove, one end of the elastic member abutting the mounting groove and the other end abutting the free end, and the elastic member can apply a force to the free end that constantly tends to move it outward.

[0017] In some embodiments, two sets of locking members are symmetrically arranged on the fixed snap ring, each set of locking members includes two locking members, and two symmetrically arranged elastic members are arranged on the fixed snap ring, each elastic member is associated with two locking members, the free ends of the two locking members are arranged close to each other, the locking end of one of the locking members is located at the end of the free end away from the other locking member, and the free ends of the two locking members are all connected to the elastic members, the free ends include connecting portions for connecting the elastic members, and the connecting portions are formed on the sides of the free ends facing the fan body, and the connecting portions are arranged on the free ends of the two locking members and are engaged into the elastic members, thereby realizing that the locking members are connected to the elastic members and will not come off.

[0018] Specifically, after the locking member is rotated until the locking portion of its locking end engages with the locking mating portion of the fan body and is locked, the elastic member applies an outward thrust to the free end, so that the locking portion can be firmly engaged in the locking mating portion and will not come off. When the free end is pressed, the locking end moves away from the fan body, the locking portion disengages from the locking mating portion, and the lock is released. After the hand is released, the elastic member applies an outward thrust to the free end, so that the locking end tends to move toward the fan body.

[0019] In some embodiments, the fan body includes an outer housing, fan blades disposed within the outer housing, a motor powering the fan blades, a PCB board electrically connected to the motor, and a DC male connector electrically connected to the PCB board.

[0020] Specifically, the DC male connector is a metal copper DC male connector that is fixed to the PCB board, has good conductivity, is compact and not easy to disconnect, and the thinner fan blades can increase the fan's rotation speed and air volume, effectively reducing the load on the motor and extending its service life. At the same time, the reduced load can reduce power consumption and extend the service life of the external power battery. The motor uses a brushless motor, which has a long service life, high efficiency and small volume.

[0021] In some embodiments, the outer housing includes a rear casing having an open front end and a front cover plate connected to the rear casing with screws, the lock snap ring is covered by the rear casing, and the lock member can pass through the lock snap ring and engage with the rear casing to lock it.

[0022] With the above solution, the front cover plate and the rear casing are detached in a spiral manner, which is convenient for cleaning dirt and dust from the fan blades later.

[0023] In some embodiments, the front cover plate includes a flexible annular wall extending into the rear casing, and a front mesh cover connected to a front end of the annular wall for enclosing the fan blades, wherein an external thread is formed on the outer wall of the annular wall, an internal thread that fits onto the external thread is formed on the inner wall of the rear casing, and a circular protrusion that protrudes outward in the circumferential direction is formed at the connection portion of the annular wall with the front mesh cover, and the circular protrusion exceeds the outer wall of the lock snap ring.

[0024] Specifically, the provision of the annular protrusion makes it easier to attach and detach the fixing snap ring to the fan body, and also makes it easier to attach and detach the front cover plate to the rear casing.

[0025] In some embodiments, the rear end of the rear casing has an inwardly recessed accommodating groove for accommodating the motor, the PCB board, and the DC male connector, the bottom wall of the accommodating groove has a through-hole through which the driving end of the motor passes and engages with the fan blade, and a motor rear cover is detachably connected to the top of the accommodating groove, and the motor rear cover is made of a silicone material, which can effectively fulfill the role of waterproofing.

[0026] Specifically, an opening communicating with the receiving groove is provided on the side wall of the rear casing, thereby exposing the DC male connector for connection to an external driving battery, and the motor rear cover is covered by the DC male connector, ensuring a tight seal between the motor rear cover and the DC male connector and providing excellent waterproofing.

[0027] In some embodiments, a groove is provided at the end of the bottom wall of the accommodating groove that is close to the fan blade, and the groove is filled with lubricating grease, which can lubricate the motor bearings, extend the service life of the motor, and prevent water molecules from entering the motor and damaging it.

[0042] Also, in the following description, specific details are provided to provide a thorough understanding of the examples, but it will be apparent to those skilled in the art that the examples may be practiced without these specific details.

[0043] Hereinafter, the technical solutions provided by the embodiments of the present application will be described with reference to the drawings. As shown in Figures 1 to 11, this utility model provides a fan for air-conditioned clothing, including a fan body 100 and a locking structure 200 capable of locking the fan body 100 to the air-conditioned clothing, the locking structure 200 including a locking snap ring 201 detachably connected to the outside of the fan body 100, and a locking member 202 movably connected to the locking snap ring 201 and passing through the locking snap ring 201 to engage with and lock the fan body 100. Using the above solution, the locking snap ring 201 detachably connected to the fan body 100 allows for easy attachment and detachment of the two, facilitating removal of the fan body and facilitating subsequent maintenance. At the same time, the installation of the locking member 202 ensures a strong fastening force between the locking snap ring 201 and the fan body 100 after assembly, making them less likely to come apart.

[0044] In some embodiments, the locking member 202 includes a locking portion 2021 protruding from and adjacent to 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, and an opening 2011 is provided in the locking snap ring 201 for the locking portion 2021 to pass through. Specifically, the provision of 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 locking between the locking member 202 and the fan body 100 is achieved by the engagement between the locking portion 2021 and the locking engagement portion 101, thereby achieving the locking and fixing between the locking snap ring 201 and the fan body 100. In some embodiments, the locking portion 2021 includes a first mating surface 2021a extending along the vertical direction and a second mating surface 2021b extending at an angle along the axial direction, and the first mating surface 2021a and the second mating surface 2021b intersect at an end close to the locking mating portion 101, and correspondingly, the locking mating portion 101 includes a first abutment surface 1011 abutting the first mating surface 2021a and a second abutment surface 1012 abutting the second mating surface 2021b. Specifically, after the locking portion 2021 engages with the locking fitting portion 101, the first fitting surface 2021a abuts against the first abutment surface 1011, and the second fitting surface 2021b abuts against the second abutment surface 1012, thereby restricting the axial movement of the locking portion 2021, thereby achieving a strong lock between the locking portion 2021 and the locking fitting portion 101.

[0045] In some embodiments, the locking member 202 is rotatably connected to the locking snap ring 201 via a rotating shaft 203, and the locking member 202 has a locking end 2022 and a free end 2023 formed at both ends of a rotational connection portion with the rotating shaft 203, and the locking end 2022 and the free end 2023 can rotate around the rotating shaft 203, and the locking portion 2021 is provided on the locking end 2022. Specifically, three locking portions 2021 are provided on the locking end 2022 facing the fan body 100, and they are equally spaced along the axial direction. In some embodiments, the rotating shaft 203 is fixed to the locking snap ring 201, and the openings 2011 are provided on both sides of the rotating shaft 203 in the locking snap ring 201, thereby ensuring normal rotation of the locking end 2022 and the free end 2023. In some embodiments, the free end 2023 and the lock end 2022 are integrally connected along the circumferential direction of the lock snap ring 201 and can rotate around the rotation axis 203.Specifically, when the locking member 202 rotates around the rotation axis 203, the locking end 2022 moves toward the fan body 100 until the locking portion 2021 of the locking end 2022 engages with the locking fitting 101 of the fan body 100, thereby realizing a fixed connection between the locking snap ring 201 and the fan body 100. Furthermore, when the locking end 2022 moves toward the fan body 100, the free end 2023 moves away from the housing. Similarly, when the free end 2023 is pressed and moved in a direction approaching the fan body 100, the locking end 2022 is driven to move synchronously in a direction away from the fan body 100, whereby the locking portion 2021 disengages from the lock fitting portion 101 of the fan body 100, and unlocking is achieved between the locking end 2022 and the fan body 100, whereby the locking snap ring 201 and the fan body 100 are unlocked, and the fan body 100 and the locking snap ring 201 can be separated. In some embodiments, therefore, the locking snap ring 201 has a mounting groove 2012 disposed near the free end 2023, and an elastic member 204 disposed in the mounting groove 2012, one end of the elastic member 204 abutting against the mounting groove 2012 and the other end abutting against the free end 2023, and the elastic member 204 can apply a force to the free end 2023 that constantly tends to move it outward.In some embodiments, the fixed snap ring has two sets of locking members 202 symmetrically arranged, each set of locking members 202 includes two locking members 202, and the fixed snap ring has two symmetrically arranged elastic members 204, each elastic member 204 is associated with two locking members 202, the free ends 2023 of the two locking members 202 are arranged close to each other, and the locking end 2022 of one of the locking members 202 is connected to the end of its free end 2023 away from the other locking member 202. The free ends 2023 of the two locking members 202 are all connected to the elastic member 204, and the free ends 2023 include connecting portions 2023a of the elastic member 204, and the connecting portions 2023a are formed on the side of the free ends 2023 facing the fan body 100. The connecting portions 2023a are installed on the free ends 2023 of the two locking members 202 and are engaged into the elastic member 204, thereby realizing that the locking members 202 are connected to the elastic member 204 and will not come off. Specifically, after the locking member 202 is rotated until the locking portion 2021 of its locking end 2022 engages with the locking mating portion 101 of the fan body 100 and is locked, the elastic member 204 applies an outward thrust to the free end 2023, so that the locking portion 2021 can be firmly engaged in the locking mating portion 101 and will not come off. When the free end 2023 is pressed, the locking end 2022 moves away from the fan body 100, and the locking portion 2021 disengages from the locking mating portion 101, thereby releasing the lock. After the hand is released, the elastic member 204 applies an outward thrust to the free end 2023, so that the locking end 2022 tends to move toward the fan body 100.

[0046] In some embodiments, the fan body 100 includes an outer housing 102, fan blades 103 disposed within the outer housing 102, a motor 104 for 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 metal copper DC male connector 106 fixed to the PCB board 105, and has the advantages of good conductivity, compactness, and durability. The thin fan blades 103 can increase the rotation speed and airflow of the fan, effectively reducing the load on the motor 104 and extending its service life. At the same time, the reduced load can reduce power consumption and extend the service life of an external battery. The motor 104 is a brushless motor 104, which has a long service life, high efficiency, and small volume.

[0047] In some embodiments, the outer housing 102 includes a rear casing 1021 with an open front end and a front cover plate 1022 connected to the rear casing 1021 with screws, the locking snap ring 201 is covered by the rear casing 1021, and the locking member 202 can penetrate the locking snap ring 201 and engage with and lock into the rear casing 1021. Using the above solution, the front cover plate 1022 and the rear casing 1021 can be attached and detached in a spiral manner, which makes it convenient to clean dirt and dust from the fan blades 103 later. In some embodiments, the front cover plate 1022 includes a flexible annular wall 1022a extending into the rear casing 1021 and a front mesh cover 1022b connected to the front end of the annular wall 1022a and enclosing the fan blades 103. An external thread 1022c is formed on the outer wall of the annular wall 1022a, an internal thread 1021a is formed on the inner wall of the rear casing 1021 and is fitted with the external thread 1022c. Furthermore, a circular protrusion 1022d is formed at the connection portion of the annular wall 1022a and the front mesh cover 1022b, protruding outward in the circumferential direction, and the circular protrusion 1022d extends beyond the outer wall of the locking snap ring 201. Specifically, the presence of the circular protrusion 1022d facilitates the attachment and detachment of the fixing snap ring to the fan body 100, and also facilitates the attachment and detachment of the front cover plate 1022 to and from the rear casing 1021.

[0048] In some embodiments, a receiving groove 1021b is recessed inward at the rear end of the rear casing 1021 to receive the motor 104, the PCB board 105, and the DC male connector 106. A through-hole 1021c is formed in the bottom wall of the receiving groove 1021b, through which the driving end of the motor 104 passes and engages with the fan blades 103. A motor rear cover 1023 is detachably connected to the top of the receiving groove 1021b, and the motor rear cover 1023 is made of a silicone material to effectively provide waterproofing. Specifically, an opening communicating with the receiving groove 1021b is formed in the side wall of the rear casing 1021, thereby exposing the DC male connector 106 for connection to an external driving battery. The motor rear cover 1023 is covered by an AC connector, ensuring 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 at the end of the bottom wall of the accommodating groove 1021b close to the fan blade 103, and the groove 1021d is filled with lubricating grease, which can lubricate the bearings of the motor 104, extend the service life of the motor 104, and prevent water molecules from entering the motor 104 and damaging it.
