Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to a cooling device. Background Art

[0002] Neck-hanging fans and clamping thermostats are portable heat dissipation devices that help the human body cool down. They can free the user's hands and are convenient for the user to use during outdoor activities to cool the user's body. However, existing neck-hanging fans can usually only be hung on the user's neck, and cannot be inserted into the inside of clothes to blow air or cool down. The heat dissipation port and air inlet of existing clamping thermostats are usually integrated. When the user clamps the clamping thermostat on the clothes, although the clamping thermostat can cool down the user's body and achieve the effect of temperature regulation and heat dissipation, the heat dissipation port of the clamping thermostat will inevitably blow the hot air inside it toward the human body, giving the user a bad experience; and the air inlet will be blocked by the clothes and cannot be smoothly intake.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the utility model, not all the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application.

[0025] Neck hanging fans and clamping temperature control devices are portable heat dissipation devices that help cool the human body. They can free the user's hands and are convenient for users to use during outdoor activities to cool the user's body.

[0026] However, existing neck-hanging fans can usually only be hung on the user's neck and blow air to the user's neck or face and other exposed skin, but cannot extend into the clothes to blow air or cool the skin wrapped inside the clothes. The cooling efficiency and cooling effect of existing neck-hanging fans are both low.

[0027] The heat dissipation port of the existing clamping thermostat is usually integrated. When the user clips the clamping thermostat on the clothes, although the clamping thermostat can blow air to the user's body to achieve the effect of cooling and dissipating heat, the heat dissipation port of the clamping thermostat will inevitably blow the hot air inside to the human body, which will give the user a bad experience. Specifically, the existing clamping thermostat can usually only fan the airflow but does not have a cooling function. The heat on the user's skin is taken away by the airflow. The cooling efficiency and cooling effect of the existing clamping thermostat are both low.

[0028] Based on the above problems, an embodiment of the present application provides a cooling device, which can be used to cool the user's body. When the user wears clothes, the cooling device can be hung on the clothes and inserted into the clothes to cool the user's body.

[0029] For details, please refer to Figure 1 and Figure 2 The cooling device 1 provided in the embodiment of the present application may include: a shell 10, a refrigeration component 20 and a fan 30. The refrigeration component 20 may be arranged in the shell 10 and used to generate cold energy to cool down the user. The fan 30 may also be arranged in the shell 10 and used to generate airflow to blow away the heat generated by the refrigeration component 20 in the process of generating cold energy, so as to avoid heat accumulation inside the shell 10.

[0030] In this embodiment, the shell 10 may include a first structure portion 110 and a second structure portion 130 , wherein the second structure portion 130 may include a connecting portion 120 , and the connecting portion 120 may be connected to the first structure portion 110 , that is, in this embodiment, the second structure portion 130 may be connected to the first structure portion 110 through the connecting portion 120 .

[0031] Furthermore, the connecting portion 120 is a hollow structure, and the connecting portion 120 can be configured to be deformable, that is, the second structural portion 130 can be folded back relative to the first structural portion 110, and a hanging space 70 is formed between the first structural portion 110. It should be noted that the above-mentioned hanging space 70 can be used for users to wear. When the user wears the cooling device 1, the collar can be located in the hanging space 70, the first structural portion 110 can be located on the inside of the clothes, and the second structural portion 130 can be hung on the outside of the clothes. It should be noted that the above-mentioned folding setting refers to a structure in which one end of the first structural portion 110 extends toward the other end of the first structural portion 110, so that the second structure is stacked with the first structural portion.

[0032] It is understandable that the embodiment of the present application does not limit the specific deformable mode of the above-mentioned connecting portion 120. For example, in addition to the above-mentioned folding, it can also be bent, curved, etc., which can be set according to actual conditions. The first structural portion 110 and the second structural portion 130 are internally connected. It should be noted that the embodiment of the present application does not limit the specific form and structure of the first structural portion 110 and the second structural portion 130. For example, in one embodiment, the first structural portion 110 and the second structural portion 130 can be set as a sheet-like structure, and the second structural portion 130 can be folded back to be stacked with the first structural portion 110. By extending the collar into the hanging space 70, it is convenient for the user to hang the second structural portion 130 on the outside of the collar and extend the first structural portion 110 into the clothes to cool the user's body.

[0033] In this embodiment, the first structural part 110 may include a contact surface 112 that fits against the skin and a side surface 113 connected to the contact surface 112. When the user installs the cooling device 1 on the collar, the contact surface 112 of the first structural part 110 can fit against the user's skin, and the cold energy generated by the refrigeration component 20 can be transferred to the user through the contact surface 112, thereby cooling the user.

[0034] The second structural portion 130 may include an inner surface facing the neck hanging space 70, an outer surface opposite to the inner surface, and a side surface connected between the inner surface and the outer surface. When the cooling device 1 is installed on the user's collar, the inner surface may contact the user's collar, and the outer surface may face away from the collar and toward the outside of the collar.

[0035] Furthermore, in one embodiment, the connecting portion 120 can be set as a flexible structure to realize the deformable property of the connecting portion 120. When the connecting portion 120 is configured as a flexible structure, the user can bend the connecting portion 120 to change the relative position relationship between the second structural portion 130 and the first structural portion 110, thereby making it easier for the user to hang the cooling device 1 on the collar.

[0036] Furthermore, the embodiments of the present application do not limit the specific structure of the connection portion 120 . For example, in one embodiment, the connection portion 120 may be silicone, and the flexibility of the silicone is utilized to achieve the bendable property of the connection portion 120 .

[0037] For another example, in one embodiment, a rotating shaft structure may be provided inside the connecting portion 120. Specifically, in this embodiment, the connecting portion 120 may be provided with a rotating shaft coated with silicone to ensure that a closed structure is formed between the first structural portion 110, the second structural portion 130 and the outer surface of the connecting portion 120. The structure may be provided specifically according to actual conditions and is not limited here. It should be noted that when the connecting portion 120 is a rotating shaft coated with silicone, the rotating shaft is configured to drive the first structural portion 110 to move closer to or farther from the second structural portion 130 when the rotating shaft rotates, so that the user can hang the cooling device on the collar and clamp or remove it from the collar.

[0038] In addition, the embodiment of the present application also does not limit the specific connection method of the first structural part 110, the connecting part 120 and the second structural part 130. For example, in one embodiment, the first structural part 110, the connecting part 120 and the second structural part 130 can be set as an integrally formed structure, which can improve the structural strength of the entire housing 10. For example, in another embodiment, the first structural part 110, the connecting part 120 and the second structural part 130 can be set in a detachable connection form, such as a snap connection, bonding or interference connection, etc. When the housing 10 is damaged, the detachable connection form can facilitate the user to replace the first structural part 110, the connecting part 120 and the second structural part 130 separately, which is conducive to reducing the user's use cost. It can be set according to actual conditions and is not limited here.

[0039] Furthermore, the shell 10 may be provided with an air inlet 160 and an air outlet 170, and an air flow channel 140 may be formed inside the shell 10. The air inlet 160 and the air outlet 170 may be connected to the air flow channel 140. External air may enter the air flow channel 140 from the air inlet 160 and flow out of the air flow channel 140 from the air outlet 170. The air flow channel 140 may enable air flow exchange between the inside of the shell 10 and the outside of the shell 10.

[0040] It should be noted that the embodiment of the present application does not limit the specific number and shape of the air inlet 160 and the air outlet 170. For example, the air inlet 160 can be set to multiple, and the air outlet 170 can also be set to multiple, which can promote the flow of air in the housing 10. In addition, in the present embodiment, the air inlet 160 can be set to a strip structure. In some other embodiments, the air inlet 160 can also be set to a circular, elliptical or other structure, which can be set specifically according to the user's preferences. The air outlet 170 can be set to the same structure as the air inlet 160, which can reduce the difficulty of production. The specific structure of the air outlet 170 can refer to the structure of the air inlet 160, and will not be repeated here.

[0041] Specifically, in the present embodiment, the air outlet 170 can be disposed on the second structural portion 130. For example, in one embodiment, the air outlet 170 can be disposed on the outer surface of the second structural portion 130. In another embodiment, the air outlet 170 can be disposed on the side surface of the second structural portion 130. In yet another embodiment, the air outlet 170 can be disposed on both the outer surface and the side surface of the second structural portion 130. This can prevent the air outlet 170 from discharging hot air from the first structural portion 110, thereby preventing the hot air from blowing toward the user's body.

[0042] Preferably, the air outlet 170 can be arranged on the surface of the second structure part 130 away from the first structure part 110, that is, the air outlet 170 can be arranged on the outer surface of the second structure part 130. It should be noted that since the refrigeration component 20 also generates heat while generating cold, the setting of the above-mentioned air outlet 170 is conducive to discharging the heat away from the first structure part 110, thereby avoiding the heat generated by the refrigeration component 20 from being transferred to the user, which is conducive to improving the refrigeration effect of the cooling device 1 and improving the user experience.

[0043] In one embodiment, the setting position of the air inlet 160 can be the same as the setting position of the air outlet 170. For example, the air inlet 160 can be set on any surface of the second structure part 130 except the surface close to the first structure part 110, that is, the air inlet 160 can be set on any surface of the second structure part 130 except the inner surface, so that the surface of the second structure part 130 away from the first structure part 110 can be fully utilized, and the user's clothes can be prevented from blocking the air inlet 160. Preferably, in one embodiment, the air inlet 160 can be set on the surface of the second structure part 130 away from the first structure part 110 and located on one side of the air outlet 170, that is, in this embodiment, the air inlet 160 and the air outlet 170 can be both set on the outer surface of the second structure part 130.

[0044] For further information, see Figure 3 In the present embodiment, a partition 150 may be further provided in the housing 10. The partition 150 may be provided in the first structural portion 110 and the second structural portion 130. It can be understood that the partition 150 is also provided in the connecting portion 120. The partition 150 may separate the airflow channel 140 into an air inlet channel 141 and an air outlet channel 142. The air inlet channel 141 and the air outlet channel 142 may also be interconnected to form the airflow channel 140 together.

[0045] The embodiment of the present application does not describe the specific structure of the separator 150. For example, in the present embodiment, the separator 150 may be a sheet-like structure or a plate-like structure. A connecting port 151 may be provided on the separator 150 so that the air inlet channel 141 and the air outlet channel 142 are connected. Specifically, one end of the separator 150 may be located in the second structural part 130 and between the air inlet 160 and the air outlet 170. For another example, in other embodiments, a gap may be provided between the separator 150 and the inner wall of the first structural part 110. The gap may be used to connect the air inlet channel 141 and the air outlet channel 142 and serve as the connecting port 151. Specifically, the air inlet 160 can be connected to the air inlet channel 141, and the air outlet 170 can be connected to the air outlet channel 142. The outside air can enter the air inlet channel 141 from the air inlet 160, and after passing through the connecting point between the air inlet channel 141 and the air outlet channel 142 on the partition 150, the air enters the air outlet channel 142 from the air inlet channel 141, and finally flows out of the interior of the outer shell 10 from the air outlet 170.

[0046] Please continue reading Figure 3 In this embodiment, the refrigeration assembly 20 may include a refrigeration element 210 , a heat dissipation element 220 and a thermal conductive sheet 230 .

[0047] Specifically, the refrigeration component 210 can be used to generate cold. The embodiment of the present application does not limit the specific form of the refrigeration component 210. For example, in one embodiment, the refrigeration component 210 can be a semiconductor refrigeration plate, which is a thermoelectric module based on the Peltier effect. The Peltier effect is used to conduct heat from one side to the other side through a direct current, which will cause one surface of the semiconductor refrigeration plate to generate cold and the other surface to generate heat. The cold can be used to transfer to the user and cool the user. The heat can be discharged from the interior of the housing 10 through the fan 30. For the sake of ease of explanation, the surface of the refrigeration component 210 that generates cold is referred to as the cold end, and the surface of the refrigeration component 210 that generates heat is referred to as the hot end.

[0048] In this embodiment, the refrigeration component 210 can be arranged in the air flow channel 140. Specifically, the cold end of the refrigeration component 210 can be arranged on the surface of the first structural part 110 away from the second structural part 130, so that the cold generated by the refrigeration component 210 can be directly transferred to the first structural part 110 through heat transfer, which can further improve the refrigeration effect of the cooling device 1. The hot end of the refrigeration component 210 can be arranged toward the air flow channel 140, specifically, it can be arranged toward the air outlet channel 142, so that the heat generated by the refrigeration component 210 can be discharged from the air flow channel 140.

[0049] The heat sink 220 can be used to dissipate heat from the refrigeration element 210. Specifically, since the refrigeration element 210 generates heat while generating cold, the heat sink 220 can be used to assist in dissipating the heat generated by the refrigeration element 210, thereby enabling the refrigeration element 210 to generate more cold, thereby improving the refrigeration effect of the refrigeration element 210. The embodiment of the present application does not limit the specific structure of the heat sink 220, for example, it can be silicone grease, or it can be a heat sink fin, etc., and can be specifically configured according to actual conditions.

[0050] In this embodiment, the heat sink 220 can be arranged in the air flow channel 140, specifically in the air outlet channel, and thermally coupled with the hot end of the refrigeration element 210, so that the heat generated by the refrigeration element 210 can be directly transferred to the heat sink 220 by heat transfer, which is beneficial to improving the heat dissipation efficiency of the heat sink 220.

[0051] The thermal conductive sheet 230 can be used to receive the cold energy generated by the refrigeration element 210 and transfer the cold energy to the user. In this embodiment, the thermal conductive sheet 230 can be arranged on the outside of the first structural part 110, and the thermal conductive sheet 230 can be thermally coupled with the refrigeration element 210. Specifically, in this embodiment, the thermal conductive sheet 230 can be arranged on the surface of the first structural part 110 away from the second structural part 130, that is, the thermal conductive sheet 230 can be arranged on the contact surface 112, so that the thermal conductive sheet 230 can transfer the cold energy to the user.

[0052] It should be noted that the embodiment of the present application does not limit the thermal coupling method between the thermal conductive sheet 230 and the refrigeration element 210. For example, a thermal conductive medium 240 can be provided between the thermal conductive sheet 230 and the refrigeration element 210 to achieve thermal coupling between the thermal conductive sheet 230 and the refrigeration element 210. The embodiment of the present application does not limit the specific form of the thermal conductive medium 240. For example, it can be silicone oil, or it can be an organic heat carrier, etc., which can be specifically set according to actual conditions. It can be understood that in one embodiment, a thermal conductive medium can be provided between the refrigeration element 210, the thermal conductive sheet 230 and the heat sink 220, which can further promote the refrigeration element 210 to transfer heat to the heat sink 220, and transfer heat to the thermal conductive sheet 230, which is beneficial to improve the refrigeration efficiency of the refrigeration element 210, and then improve the cooling efficiency of the cooling device 1.

[0053] For further information, see also Figure 4 and Figure 5In one embodiment, a window 111 may be provided on the contact surface 112 of the first structural part 110, and the refrigeration part 210 may be exposed from the window 111 and thermally coupled with the thermal conductive sheet 230. The embodiment of the present application does not limit the shape of the window 111, for example, it may be square, circular, or other user-defined shapes, etc., which may be set according to actual conditions. In this embodiment, the thermal conductive sheet 230 may be set to at least cover the window 111, for example, the coverage area of ​​the thermal conductive sheet 230 may be set to be the same as the area of ​​the window 111, and the thermal conductive sheet 230 covers the window 111, and for another example, the coverage area of ​​the thermal conductive sheet 230 may be set to be the same as the area of ​​the contact surface 112, and the thermal conductive sheet 230 covers the window 111. When the first structural part 110 and the thermal conductive sheet 230 are thermally coupled through the thermal conductive medium 240, the thermal conductive medium 240 may be set at the above-mentioned window 111.

[0054] The fan 30 can be disposed in the air flow channel 140. Specifically, the fan 30 can be disposed at the connection point between the air inlet channel 141 and the air outlet channel 142. The fan 30 can be used to generate airflow through the refrigeration component 20 and be discharged from the air outlet 170. Specifically, when the outside air flows into the air inlet channel 141 from the air inlet 160, the fan 30 can suck the air into the air outlet channel 142 and blow the air toward the air outlet 170 to achieve heat dissipation of the refrigeration component 210.

[0055] The embodiment of the present application does not limit the specific position of the fan 30. For example, in one embodiment, the fan 30 can be arranged in the air outlet channel 142 and correspondingly arranged at the connecting port 151, so as to suck the air in the air inlet channel 141 into the air outlet channel 142 and generate airflow in the airflow channel 140. For another example, in another embodiment, the fan 30 can also be arranged at the connecting port 151, so that the air in the air inlet channel 141 can also be sucked into the air outlet channel 142 and generate airflow in the airflow channel 140.

[0056] Furthermore, in one embodiment, the housing 10 may also be provided with a blowing port 180, which may be provided on the first structural portion 110 and located on a side of the refrigeration assembly 20 close to the air inlet 160, and the blowing port 180 is connected to the air flow channel 140, so that the blowing port 180 may be prevented from blowing the heat generated by the refrigeration assembly 20 to the user. The embodiment of the present application does not limit the specific structure of the blowing port 180, for example, it may be provided with the same structure as the air inlet 160, which will not be described in detail herein.

[0057] Specifically, in this embodiment, the air outlet 180 can be set on the side 113 of the first structural part 110. The embodiment of the present application does not limit which side 113 the air outlet 180 is set on, and it can be set according to actual conditions. Preferably, in this embodiment, the heat sink 220 and the fan 30 can both be arranged in the air outlet channel 142, and the heat sink 220 can be arranged close to the connecting portion 120, the blowing port 180 can be arranged on the side 113 of the first structural portion 110 away from the connecting portion 130, and the blowing port 180 is located on the side of the fan 30 away from the heat sink 220. When the cooling device 1 is installed on the user's collar, the side 113 of the first structural portion 110 away from the connecting portion 130 can point to the user's back. The blowing port 180 is arranged here to blow air to the user's back for cooling, and at the same time, it can avoid blowing the heat generated by the refrigeration component 20 toward the user. In this embodiment, the fan 30 can simultaneously achieve the effect of dissipating heat to the heat sink 220 and blowing air to the user, which is beneficial to improving the cooling effect of the cooling device 1.
