[0023] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0024] Please refer to Figures 1 to 3A retractable pull ring heater includes a housing 1, a heating and cooling component and a pull ring 7. The heating and cooling component is provided inside the housing 1, and the pull ring 7 is rotatably provided on both sides of the housing 1. The housing 1 has a fixing groove 123 on both sides corresponding to the pull ring 7.

[0025] As can be seen from the above description, the beneficial effects of this utility model are as follows: the pull ring 7 of the heat exchanger is used to connect with the strap to fix the heat exchanger to the treatment area; through the rotatable setting of the pull ring 7, the angle of the treatment area can be adjusted by rotating the pull ring 7 after the strap is tied; and the pull ring 7 can be stored in the fixing groove 123 to reduce the overall volume and facilitate carrying.

[0026] Furthermore, the pull ring 7 is detachably connected to the fixing groove 123.

[0027] As can be seen from the above description, the detachable connection between the pull ring 7 and the fixing groove 123 prevents the pull ring 7 from rotating and falling out of the fixing groove 123 when it is stored due to shaking or other reasons.

[0028] Furthermore, the fixing groove 123 is provided with a slot 124, and the pull ring 7 is provided with a locking point 71 on the side of the fixing groove 123 where the slot 124 is provided.

[0029] As can be seen from the above description, the snap-fit ​​of the slot 124 in the fixing groove 123 with the snap-fit ​​point 71 on the pull ring 7 achieves a detachable connection between the pull ring 7 and the fixing groove 123.

[0030] Furthermore, a notch 125 is provided in the middle of one side edge of the fixing groove 123, and a protruding lifting block 72 is provided on the pull ring 7, the lifting block 72 pressing against the notch 125.

[0031] As can be seen from the above description, the recess 125 of the fixing groove 123 provides clearance space, and when the user needs to lift the pull ring 7, he / she can lift the lifting block 72 at the recess 125 so that the pull ring 7 can rotate out of the fixing groove 123.

[0032] Furthermore, one side of the housing 1 is a working surface, and the heating and cooling components are located on the working surface; a vibration motor 9 is provided inside the housing 1, and the vibration motor 9 abuts against the working surface.

[0033] As can be seen from the above description, the vibration function of the device is achieved by arranging the vibration motor 9 against the working surface.

[0034] Furthermore, it also includes a fan 5, which is disposed inside the housing 1; the upper side of the housing 1 is provided with an air inlet 112, and the side of the housing 1 is provided with an air outlet 122; an air guide cover 4 is provided between the fan 5 and the air inlet 112, and the middle part of the air guide cover 4 is connected to the fan 5; the air guide cover 4 is disc-shaped, and its edge and the middle part have an arc-shaped connecting surface.

[0035] As described above, the fan 5 dissipates heat from the heating and cooling components. Outside air is drawn into the housing 1 from the air inlet 112 on the upper side of the housing 1 by the fan 5 and exchanges heat with the heating and cooling components before being discharged from the air outlet 122 on the side of the housing 1. The arc-shaped connecting surface of the air guide cover 4 allows the air drawn in from the air inlet 112 to quickly gather in the middle of the air guide cover 4 under the guidance of the arc-shaped connecting surface and exchange heat with the heating and cooling components quickly through the fan 5.

[0036] Furthermore, it also includes a battery 8, which is disposed between the side of the heating and cooling component and the inner wall of the housing 1. The battery 8 is electrically connected to the heating and cooling component, and the battery 8 is a pouch battery 8.

[0037] As described above, the design of using a pouch battery 8 between the side of the heating and cooling component and the inner wall of the housing 1 utilizes the flat structure of the pouch battery 8 to fill the space between the heating and cooling component and the housing 1, making the structure more compact and effectively reducing the size of the device and the large space occupied by the traditional cylindrical battery 8.

[0038] Furthermore, it also includes a radiator 6, which is disposed between the fan 5 and the heating / cooling components.

[0039] As can be seen from the above description, heat exchange over a larger area is achieved through radiator 6, thereby accelerating heat dissipation efficiency.

[0040] Furthermore, the housing 1 includes an upper housing 11 and a lower housing 12, the upper housing 11 and the lower housing 12 being fastened together; a first mounting bracket 111 extends from the interior of the upper housing 11 toward the lower housing 12, and a second mounting bracket 121 extends from the interior of the lower housing 12 toward the upper housing 11; a fan 5 is provided in the first mounting bracket 111, and a heat sink 6 is provided in the second mounting bracket 121.

[0041] As can be seen from the above description, the housing 1 adopts a combination of upper housing 11 and lower housing 12; the fan 5 and the heat sink 6 are fixed by the first mounting bracket 111 of the upper housing 11 and the second mounting bracket 121 of the lower housing 12 respectively, forming a compact installation structure.

[0042] Furthermore, it also includes a battery 8, and the first mounting bracket 111 and the second mounting bracket 121 have a space with the inner wall of the upper shell 11 and the inner wall of the lower shell 12, and the battery 8 is assembled in the space.

[0043] As can be seen from the above description, the first mounting bracket 111 and the second mounting bracket 121 are not only the fixing structures for the tail fan 5 and the heat sink 6, but also cooperate with the inner wall of the housing 1 to form the assembly space for the battery 8. The reasonable arrangement of the structural space makes the device compact.

[0044] Example 1:

[0045] like Figures 1 to 3 As shown, the retractable pull ring heat exchanger of this embodiment includes a housing 1, a heat exchange component, a fan 5, a radiator 6, a battery 8, a circuit component, a vibration motor 9, and a pull ring 7.

[0046] The housing 1 includes an upper shell 11 and a lower shell 12, which are fastened together. An air inlet 112 is provided at the top of the upper shell 11. A first mounting bracket 111 extends from the interior of the upper shell 11 toward the lower shell 12, and a second mounting bracket 121 extends from the interior of the lower shell 12 toward the upper shell 11. A fan 5 is disposed within the first mounting bracket 111, and a heat sink 6 is disposed within the second mounting bracket 121. An air guide cover 4 is provided between the upper shell 11 and the fan 5, and the middle part of the air guide cover 4 communicates with the fan 5. The air guide cover 4 is disc-shaped, with an arc-shaped connecting surface between its edge and its center. A snap-fit ​​block is provided on the side of the air guide cover 4 near the fan 5, which is fixedly engaged with the edge of the fan 5.

[0047] The lower shell 12 has an air outlet 122 on its side and a contact port at its bottom. The heating and cooling assembly includes a semiconductor heating and cooling sheet 2 and a heating and cooling conductor 3. The heating and cooling conductor 3 is snapped into the contact port to form a working surface, serving as a contact structure with the care area. The vibration motor 9 is located inside the lower shell 12 and abuts against the heating and cooling conductor 3. The semiconductor heating and cooling sheet 2 is provided between the heat sink 6 and the heating and cooling conductor 3.

[0048] The first mounting bracket 111 and the second mounting bracket 121 have spaces with the inner walls of the upper shell 11 and the lower shell 12, respectively, and the battery 8 is assembled within these spaces. The battery 8 is a flat, pouch battery. Specifically, a circuit assembly for adjusting the function of the device is also provided within this space. The circuit assembly is electrically connected to the battery 8, the heating / cooling assembly, and the fan 5.

[0049] Pull rings 7 are rotatably provided on both sides of the lower shell 12, and fixing grooves 123 are provided on both sides of the shell 1 corresponding to the pull rings 7. A slot 124 is provided in the fixing groove 123, and a locking point 71 is provided on the side of the pull ring 7 and the fixing groove 123 where the slot 124 is provided; a notch 125 is provided in the middle of one side edge of the fixing groove 123, and a protruding lifting block 72 is provided on the pull ring 7, which abuts against the notch 125.

[0050] Specifically, the housing 1 is generally rectangular, the lower housing 12 has four sides, the pull ring 7 is located on the side of the lower housing 12 parallel to its length direction, and the air outlet 122 is located on the side of the lower housing 12 parallel to its width direction. The circuit assembly has a charging port and an operation button on the side of the upper housing 11 on the same side as the air outlet 122.

[0051] The edges of the upper shell 11 with the air inlet 112 and the lower shell 12 with the air outlet 122 are both curved. This curved surface design ensures that even if the sides of the upper shell 11 and the lower shell 12 are parallel and close to the care area, the air inlet 112 or the air outlet 122 at the curved surface can still ensure the heat dissipation of the device.

[0052] In summary, the present invention provides a retractable pull ring for a heat exchanger. The pull ring of the heat exchanger is used to connect with a strap to fix the heat exchanger to the treatment area. Due to the rotatable design of the pull ring, the angle of the treatment area can be adjusted by rotating the pull ring after the strap is attached. The retractable design of the pull ring in the fixing groove can reduce the overall volume and make it easy to carry.
