[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] An embodiment of this utility model provides a refrigeration device 10, such as... Figures 1 to 5 As shown, the refrigeration device 10 includes a housing 110, a liquid storage tank 120, and a pump body 130. The liquid storage tank 120 is located inside the housing 110 and installed on the inner wall of the housing 110. A contoured groove 121 is provided on the side of the liquid storage tank 120 facing the base 111. The pump body 130 is located inside the housing 110 and positioned at the contoured groove 121, and is connected to the liquid storage tank 120. This application solves the problem of low internal space utilization leading to a large size in existing refrigeration devices 10. This refrigeration device 10, while having a refrigeration function, has a more compact overall structure, is easier to carry, and provides a better user experience.

[0040] Specifically, the overall layout of the refrigeration device 10 is optimized. A contoured groove 121 is provided on the liquid storage tank 120, and the pump body 130 is installed in the contoured groove 121. While fixing the pump body 130, the space around the pump body 130 can be fully utilized, which improves the utilization rate of the internal space of the housing 110. This makes the overall structure of the refrigeration device 10 more compact, effectively reduces the volume of the entire housing 110, and improves the portability of the refrigeration device 10.

[0041] In this application, the shape of the contour groove 121 can be freely adjusted according to the outer contour shape of the pump body 130, and is not limited herein. Preferably, in this application, the pump body 130 is cylindrical, and the contour groove 121 has a first arc-shaped surface that matches the outer contour shape of the pump body 130. The first arc-shaped surface of the contour groove 121 can increase the contact area with the pump body 130, so as to better limit and fix the pump body 130. In one embodiment, a contour seat 1111 is provided on the inner wall of the housing 110. The contour seat 1111 is disposed opposite to the contour groove 121 to clamp the pump body 130 between the contour groove 121 and the contour seat 1111. In this way, the contour seat 1111 provides good support for the pump body 130, and the pump body 130 is clamped between the contour seat 1111 and the contour groove 121, which further strengthens the limiting installation of the pump body 130.

[0042] Preferably, the contour seat 1111 has a second arc-shaped surface on the side facing the pump body 130. The second arc-shaped surface is adapted to the outer contour shape of the pump body 130 to improve the reliability of the connection with the pump body 130 and improve the connection stability.

[0043] Reference Figure 5 and Figure 6 In one embodiment, the housing 110 has a plurality of connecting posts 1112 on the side facing the liquid storage tank 120 where the contour groove 121 is provided. The plurality of connecting posts 1112 are arranged around the contour base 1111. The liquid storage tank 120 has a plurality of connecting ears 124, and the positions of the plurality of connecting ears 124 correspond one-to-one with the plurality of connecting posts 1112. The refrigeration device 10 also includes a plurality of screws, each screw passing through a corresponding connecting ear 124 and threadedly connected to a corresponding connecting post 1112. In this way, the fastening force formed by the screws and connecting posts 1112 allows the liquid storage tank 120 to apply pressure to the pump body 130, thereby allowing the pump body 130 to be securely clamped at the mounting position of the contour groove 121 and the contour base 1111.

[0044] Refer again Figure 5In one embodiment, the refrigeration device 10 further includes a control circuit board 150, which is electrically connected to the pump body 130. The control circuit board 150 is installed inside the housing 110 and located between the liquid storage tank 120 and the housing 110. The control circuit board 150 has a clearance hole 151, through which the pump body 130 passes to be sandwiched between the contour groove 121 and the contour seat 1111. Thus, the clearance hole 151 allows the control circuit board 150 to be accommodated between the liquid storage tank 120 and the housing 110, further utilizing the remaining space between the pump body 130, the liquid storage tank 120, and the housing 110, improving the utilization rate of the internal space of the housing, making the overall layout more compact, and reducing the volume of the housing.

[0045] It is worth mentioning that the control circuit board 150 is adjacent to the pump body 130, which facilitates the connection and conduction of the two circuits, reduces the length of the circuits, and makes the circuit layout easier.

[0046] Reference Figure 1 - Figure 3 In one embodiment, the refrigeration device 10 further includes a control switch 160 located beside the liquid storage tank 120 and exposed outside the housing 110. The control switch 160 is electrically connected to the pump body 130 via a control circuit board 150. Specifically, the control switch 160 is located in the liquid storage tank 120 in a first direction (e.g., Figure 3 On one side of the housing 110 (as shown in the X direction), and close to the control circuit board 150, the housing 110 has a first opening 1121, which corresponds to the position of the control switch 160, allowing the operating end of the control switch 160 to be exposed outside the housing 110. The portion of the control switch 160 located inside the housing 110 is close to the liquid storage tank 120 and the housing 110. This reduces the spacing between components, making the overall layout more compact.

[0047] In the above embodiments, the control switch 160 can be a toggle switch or a rotary switch. For example, in this application, the control switch 160 is a rotary switch. The user can turn the refrigeration device 10 on or off by rotating the control terminal of the control switch 160, or adjust the refrigeration device 10 to the desired setting to control the output force of the pump body 130, thus enabling the refrigeration device 10 to have different cooling intensities and making the refrigeration device 10 more versatile.

[0048] Reference Figure 7In one embodiment, the liquid storage tank 120 has a liquid inlet 122 on the side facing away from the base 111, and the liquid inlet 122 is exposed outside the housing 110; the refrigeration device 10 also includes a cover 190 and a snap-fit ​​structure 200, and the cover 190 is detachably connected to the liquid inlet 122 through the snap-fit ​​structure 200. Specifically, the snap-fit ​​structure 200 includes a snap-fit ​​groove 201 and a snap-fit ​​block 202; the snap-fit ​​groove 201 and the snap-fit ​​block 202 cooperate to allow the cover 190 to be detachably connected to the injection port 122; the snap-fit ​​groove 201 is disposed on one of the cover 190 or the injection port 122, and the snap-fit ​​block 202 is disposed on the other of the cover 190 or the injection port 122; the snap-fit ​​groove 201 includes an inlet / outlet groove section 2011 and a snap-fit ​​groove section 2012; one end of the inlet / outlet groove section 2011 is connected to the snap-fit ​​groove section 2012, and the other end extends in a first straight direction to allow the snap-fit ​​block 202 to be inserted or removed; the snap-fit ​​groove section 2012 extends in a first rotation direction, and the horizontal plane of the first rotation direction is set at an angle to the first straight direction. Thus, when removing the cover 190, simply rotate the cover 190 in the first rotational direction. The locking block 202 moves from the locking groove section 2012 into the inlet / outlet groove section 2011. Then, the cover 190 moves in the first linear direction until the locking block 202 disengages from the inlet / outlet groove section 2011, at which point the cover 190 can be separated from the injection port 122, completing the disassembly. When installation is required, the cover 190 is fastened to the injection port 122, and then rotated in the opposite direction. The upper and lower shells can then be locked again by the snap-fit ​​structure 200. In the above operation process, the cover 190 only needs to rotate a small range relative to the injection port 122 to complete the installation and disassembly, making the operation more convenient and efficient. Furthermore, the snap-fit ​​structure 200 ensures that the injection port 122 and the cover 190 are not easily separated after installation, resulting in better connection stability.

[0049] Preferably, the cover 190 has a protrusion 193 on the side facing away from the injection port 122. The protrusion 193 makes it easier for the user to apply force to the cover 190, facilitating its installation or removal.

[0050] To prevent leakage from the injection port 122 and the cap 190 after installation, refer to... Figure 7 and Figure 8 In one embodiment, the refrigeration device 10 further includes a sealing ring 240, which is fitted onto the cover 190 to improve sealing.

[0051] Specifically, the cover 190 includes a main body 191 and a cylindrical body 192. The cylindrical body 192 is located on the side of the main body 191 facing the injection port 122. The cylindrical body 192 passes through the injection port 122, and the sealing ring 240 is fitted onto the cylindrical body 192 near the main body 191.

[0052] Reference Figure 5 In one embodiment, in the second direction (e.g.) Figure 3As shown in the Y direction, the contoured groove 121 extends toward both sides of the liquid storage tank 120 and penetrates the surface wall of the liquid storage tank 120, so that both sides of the pump body 130 are exposed outside the liquid storage tank 120, which facilitates the installation and maintenance of the pump body 130.

[0053] Reference Figure 5 and Figure 6 In one embodiment, the pump body 130 includes a peripheral wall 131 opposite to the contoured groove 121, and two end walls 132 disposed opposite to each other and connected to the peripheral wall 131. One end wall 132 is provided with a first interface 1321. The liquid storage tank 120 is provided with a notch 123 on one side of the contoured groove 121. The notch 123 penetrates the groove wall of the contoured groove 121. A second interface 1231 is provided at the opening wall of the notch 123. The first interface 1321 and the second interface 1231 are located on the same side of the liquid storage tank 120. The second interface 1231 is used to connect to the interior of the liquid storage tank 120. The refrigeration device 10 also includes a first connecting pipe 140. The first connecting pipe 140 is accommodated at the notch 123, and the two ends of the first connecting pipe 140 are respectively connected to the first interface 1321 and the second interface 1231. The liquid storage tank 120 is connected to the pump body 130 via the first connecting pipe 140, enabling the pump body 130 to act on the liquid in the liquid storage tank 120, causing the liquid to flow within the first connecting pipe 140. Thus, the first connecting pipe 140 is accommodated in the notch 123, which provides wiring space for the first connecting pipe 140, effectively reducing the space occupied by the first connecting pipe 140 within the housing 110. Simultaneously, the first interface 1321 is adjacent to the second interface 1231, shortening the length of the first connecting pipe 140, making the overall structural layout more compact and reducing the volume of the refrigeration device 10.

[0054] In one embodiment, a third interface 1322 is also provided on the end wall 132 where the first interface 1321 is provided; the refrigeration device 10 further includes a cooling component 170 and a second connecting pipe 180. The cooling component 170 is located inside the housing 110 and is installed inside the housing 110 and located next to the liquid storage tank 120; the cooling component 170 includes a cold head 171, which has a refrigeration chamber. A fourth interface 1711 is provided on the side of the cold head 171 facing the liquid storage tank 120; the fourth interface 1711 communicates with the refrigeration chamber; the second connecting pipe 180 is placed at the notch 123, and the two ends of the second connecting pipe 180 are respectively connected to the third interface 1322 and the fourth interface 1711. The cooling head 171 of the cooling assembly 170 is used to cool the liquid. The third interface 1322 and the fourth interface 1711 are connected by the second connecting pipe 180, so that the cooling chamber is connected to the pump body 130, allowing the pump body 130 to transfer the liquid to the cooling chamber for cooling. In this way, the second connecting pipe 180 is partially accommodated in the notch 123, and the notch 123 also provides wiring space for the second connecting pipe 180, effectively reducing the space occupied by the second connecting pipe 180 inside the housing 110. At the same time, the cooling assembly 170 is located next to the liquid storage tank 120, so that the third interface 1322 is adjacent to the fourth interface 1711, which also shortens the length of the second connecting pipe 180, further optimizing the overall structural layout, making the structure more compact, and reducing the volume of the refrigeration device 10.

[0055] Similarly, the installation method of the cold head 171 and the housing 110 is the same as that of the liquid storage tank 120 and the housing 110, and will not be repeated here.

[0056] In one embodiment, the cooling assembly 170 further includes a thermoelectric cooler 172, which is mounted on the side of the cold head 171 facing away from the base 111 to cool the cold head 171.

[0057] In one embodiment, the cooling device 10 further includes a heat dissipation component 210, which includes a cooling fan 211 and a heat sink 212. The heat sink 212 is sandwiched between the cooling fan 211 and the thermoelectric cooler 172. The heat sink 212 can absorb the heat from the thermoelectric cooler 172, and the cooling fan 211 dissipates the heat collected by the heat sink 212 to the outside, thereby achieving heat dissipation.

[0058] Specifically, the housing 110 is provided with an air outlet 1123, which is arranged opposite to the air outlet direction of the cooling fan 211. The heat sink 212 includes a substrate and several heat sink fins, which are arranged on the side of the substrate away from the semiconductor cooling chip 172.

[0059] Reference Figure 1 and Figure 2In one embodiment, the housing 110 is further provided with two air inlets 1124, which are located on both sides of the housing 110 in the first direction to increase the air intake and ensure heat dissipation.

[0060] In one embodiment, the housing 110 includes a base 111, on which the liquid storage tank 120 and the cooling assembly 170 are both mounted. This mounting of the liquid storage tank 120 and the cooling assembly 170 on the base 111 facilitates installation and ensures their relative positions, reducing the possibility of assembly errors.

[0061] In one embodiment, the housing 110 further includes an outer cover 112, which together with the base 111 encloses a space for installing various components. An air inlet 1124, an air outlet 1123, a first opening 1121, and a second opening 1122 are all provided on the outer cover 112. The outer cover 112 and the base 111 are detachably connected to facilitate installation and maintenance.

[0062] Reference Figure 9 and Figure 10 This utility model embodiment also provides a refrigeration system 1000, which includes a refrigeration device 10, a pad 20 and a connecting pipe 30 as described in the above embodiments. A circulation pipe 21 is provided on the pad 20. The refrigeration device 10 is connected to the circulation pipe 21 through the connecting pipe 30 to cool the pad 20.

[0063] Specifically, the transfer pipe 30 also includes an inlet pipe 31 and a return pipe 32. One end of the inlet pipe 31 is connected to the cooling chamber of the cold head 171, and the other end of the inlet pipe 31 is connected to the circulation pipe 21, so that the liquid cooled by the cooling chamber can be directly transported to the pad 20 through the pump body 130. One end of the return pipe 32 is connected to the storage tank 120, and the other end of the return pipe 32 is connected to the circulation pipe 21, so that the liquid that has absorbed heat from the pad 20 can be transported to the storage tank 120 through the pump body 130. The storage tank 120 can collect the liquid that has absorbed heat. The liquid that has absorbed heat from the pad 20 is not directly transported to the cooling chamber for cooling. The storage tank 120 increases the total amount of liquid in the entire liquid circulation pipeline and allows the liquid that has absorbed heat to cool down on its own in the storage tank 120, thereby making the cooling effect of the refrigeration device 10 better.

[0064] More specifically, the liquid storage tank 120 is provided with a fifth interface 1232, and one end of the return pipe 32 is connected to the fifth interface 1232; the cold head 171 is also provided with a sixth interface 1712 on the side facing the liquid storage tank 120. The sixth interface 1712 is symmetrically arranged with the fourth interface 1711, and one end of the inlet pipe 31 is connected to the sixth interface 1712; the shell 110 is provided with a second opening 1122, which is arranged facing the liquid storage tank 120. The inlet pipe 31 and the return pipe 32 pass through the second opening 1122 to the outside of the shell 110 and are connected to the circulation pipe 21. The second opening 1122 is set close to the other end wall 132 of the liquid storage tank 120 to reduce the gap between the components and make the overall structure more compact.

[0065] In one embodiment, the circulation pipe 21 includes a first connecting part 21a, a second connecting part 21b, and a plurality of branches 21c. The other end of the inlet pipe 31 is connected to the first connecting part 21a, and the other end of the return pipe 32 is connected to the second connecting part 21b. The first connecting part 21a and the second connecting part 21b are interconnected through the plurality of branches 21c.

[0066] Preferably, the first connecting portion 21a and the second connecting portion are located on the same side of the pad 20. One end of some branches 21c is connected to the first connecting portion 21a, and one end of other branches 21c is connected to the second connecting portion 21b. Along the length of the pad 20, the other ends of several branches 21c extend away from the first connecting portion 21a and the second connecting portion 21b and are interconnected. In this way, the branches 21c can fully cover the pad 20 to improve the cooling effect.

[0067] Preferably, each branch 21c is arranged in a serpentine shape, bending and extending along the length of the pad 20 to lengthen the path of each branch 21c, so that the branch 21c is more evenly distributed on the pad 20, increasing the contact area and further improving the cooling effect.

[0068] In one embodiment, the pad 20 is provided with a fixing structure 22 for connecting to an external component. The fixing structure 22 can be configured in many ways; for example, it can be a Velcro or zipper structure, or it can be a snap-on structure 200. No limitation is made here regarding the configuration of the fixing structure 22.

[0069] In one embodiment, both the pad 20 and the circulation pipe 21 are made of soft material, which makes it easy to fit with external components and achieve a more efficient cooling effect.

[0070] This utility model embodiment also provides a wearable device (not shown in the figure), which includes the cooling system 1000 of the above embodiments and a wearable component (not shown in the figure). The pad 20 of the cooling system 1000 is installed at the wearable component. This wearable component is worn by the human body so that the cooling system 1000 can provide a cooling effect to the human body in high-temperature environments. For example, when a user is working outdoors in high temperatures in summer, they can regulate their body temperature by wearing this wearable device, enabling them to work in a safe environment and ensuring personal safety.

[0071] There are many ways to set up this wearable device, which will be described below through several embodiments. In Embodiment 1, the wearable device is clothing, and the pad 20 of the cooling system 1000 is set on the clothing. Thus, the clothing is a cooling garment. After a person wears the clothing, it can effectively regulate the body temperature, provide a comfortable working environment, and allow people to feel a continuous cooling effect, helping them stay cool in high-temperature environments, ensuring personal safety and work efficiency.

[0072] In the second embodiment, the wearable device is a backpack, which includes a bag body.
