Description

Technical Field

[0001] The utility model relates to the technical field of temperature regulating equipment, in particular to a portable temperature regulating device. Background Art

[0002] The emergence of portable fans has solved the application limitations brought by large fans. Whether in sports, outdoor activities or office use scenarios, people can carry a portable fan to meet the need of blowing wind anytime and anywhere. At present, most of the portable fans on the market are provided with a thermoelectric cooler. The thermoelectric cooler has a cold end and a hot end. The cold end can transfer cold quantity, and a large amount of heat will be generated at the corresponding hot end. Therefore, it is necessary to dissipate the heat at the hot end of the thermoelectric cooler.

[0003] Currently, the adopted means is to set a fixed air duct inside the shell of the portable fan, so as to divide the wind blown by the fan into two streams. One stream is used to dissipate the heat at the hot end of the thermoelectric cooler, and the other stream is used to blow wind to cool the user. When the cold end of the thermoelectric cooler is attached to the user to transfer cold quantity to the user, the fan can also blow wind to cool the user. However, since the fan needs to dissipate heat for the thermoelectric cooler and the air duct cannot be changed, it cannot be realized when the user only hopes to cool by the cold end of the thermoelectric cooler without the fan blowing wind. Summary of the Utility Model

[0004] In view of at least some of the problems and defects in the prior art, embodiments of the present utility model disclose a portable temperature regulating device to solve the problem that the existing portable fan cannot only cool without blowing wind.

[0005] Specifically, a portable temperature regulating device provided by an embodiment of the present utility model includes a shell, which is internally provided with a first air duct and a second air duct. The shell is provided with a shell air outlet and a heat dissipation air outlet. The first air duct communicates with the shell air outlet, and the second air duct communicates with the heat dissipation air outlet; a refrigerating member, which is arranged in the second air duct, and the refrigerating member includes a cold end and a hot end, and the cold end is used to provide cold quantity to realize refrigeration; an air duct baffle, which is arranged inside the shell and can be selectively located at a first position or a second position; a fan, which is arranged inside the shell; wherein, when the air duct baffle is located at the first position, the air flow generated by the fan blows out through the second air duct to the heat dissipation air outlet; when the air duct baffle is located at the second position, the air flow generated by the fan blows out through the first air duct and the second air duct to the shell air outlet and the heat dissipation air outlet.

One end of the connecting member is connected to the rotating shaft end and the other end is connected to the magnetic driving member.

The connecting member can move under the drive of the magnetic driving member to drive the air duct baffle to rotate, and the elastic reset member can reset the driving end of the magnetic driving member.

[0012] In an embodiment of the present invention, it further includes: a heat dissipation member, which is arranged in the second air duct and is thermally conductively connected to the hot end.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model. For the sake of understanding and convenience of description, the dimensions and thicknesses of each component shown in the drawings are arbitrarily shown, but the present utility model is not limited thereto.

[0031] It can be understood that when a component such as a layer, film, region or substrate is referred to as "on" another component, the component can be directly on the other component, or there may also be an intermediate component. Additionally, in the specification, unless explicitly described to the contrary, the word "comprising" will be understood to mean including the component, but not excluding any other components. Furthermore, in the specification, "on..." means located above or below the target component, and does not mean that it must be located on the top above based on gravity.

[0032] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] See Figure 1 , the embodiments of the present utility model provide a portable temperature regulating device 10. The portable temperature regulating device 10 provided by the embodiments of the present utility model can, for example, be used as a convenient fan (such as a neck fan, a waist fan or a hand-held fan, etc.) and / or a cooling patch. Of course, the portable temperature regulating device 10 is not limited to the above specific production equipment. For example, when the portable temperature regulating device 10 is used as a cooling patch, it can be attached to the user's skin to cool the user's skin; when the portable temperature regulating device 10 is used as a convenient fan, it can blow air for the user to cool the user.

[0034] See Figure 1, The portable temperature regulation device 10 includes, for example, a housing 100. The housing 100 includes a wearing bracket 108 and wearing arms connected to both ends of the wearing bracket. The wearing arms include a first wearing arm 106, a second wearing arm 107, and the wearing bracket 108. The wearing bracket 108 is, for example, connected between the first wearing arm 106 and the second wearing arm 107, and the first wearing arm 106 and the second wearing arm 107 extend toward the same side of the wearing bracket 108, so that the portable temperature regulation device 10 is generally in a U-shaped or C-shaped structure for easy clamping on the user's neck, wrist, etc. The first wearing arm 106, the second wearing arm 107, and the wearing bracket 108 together form a neck wearing space 109, for example. Among them, the wearing bracket 108 can be made of an elastic material. For example, a silica gel pad can be provided on the side of the wearing bracket 108 close to the user to improve the user's wearing comfort. The first wearing arm 106 and the second wearing arm 107 are used as clamping arms, and the two wearing arms can, for example, move closer to or away from each other to adapt to necks of different sizes. In a specific embodiment, the portable temperature regulation device 10 can also be provided with only the first wearing arm 106, for example, to be used as a hand-held fan.

[0035] Further, referring to Figure 2 , The portable temperature regulation device 10 includes, for example: a housing 100, a refrigerating element 200, an air duct baffle 300, and a fan 400. Among them, the housing 100 is, for example, the outer housing of the first wearing arm 10, and a cavity is formed inside it. A first air duct 110 and a second air duct 120 are provided inside the housing 100. A housing air outlet 101 and a heat dissipation air outlet 102 are provided on the housing 100. The first air duct 110 communicates with the housing air outlet 101, for example, and the second air duct 120 communicates with the heat dissipation air outlet 102. The refrigerating element 200 is, for example, disposed in the second air duct 120. The refrigerating element 200 includes a cold end and a hot end, and the cold end is used to be attached to the user to provide cold quantity to achieve refrigeration. Referring to Figure 3 and Figure 4, the air duct baffle 300 is disposed, for example, inside the housing 100 and is selectively located at the first position 111 or the second position 121. The fan 400 is disposed, for example, inside the housing 100. Wherein, when the air duct baffle 300 is located at the first position 111, the air flow generated by the fan 400 passes through the second air duct 120 to the hot end to dissipate heat from the hot end, and is blown out from the heat dissipation air outlet 102; when the air duct baffle 300 is located at the second position 121, the air flow generated by the fan 400, for example, passes through the first air duct 110 to be discharged from the housing air outlet 101, and the air flow generated by the fan 400, for example, passes through the second air duct 120 to the hot end to dissipate heat from the hot end, and is blown out from the heat dissipation air outlet 102. That is, when the air duct baffle 300 is located at the second position 121, the air flow generated by the fan 400 is divided into two streams, passing through the first air duct 110 and the second air duct 120 respectively. For example, the refrigerating member 200 mentioned above is a thermoelectric cooler. The thermoelectric cooler can achieve cooling at the cold end and heat release at the hot end based on the Peltier principle. Its working principle and specific structure can refer to the relevant technical solutions in the prior art and will not be elaborated here.

[0036] Specifically, referring to Figure 3 , a fan volute 103 is disposed inside the housing 100, and the fan 400 is disposed inside the fan volute 103. When the air duct baffle 300 is disposed at the first position 111, the air duct baffle 300 abuts against the fan volute 103, so that the air duct baffle 300 can completely block the first air duct 110. Further, the air flow generated by the fan 400 only passes through the second air duct 120 to the hot end to dissipate heat from the hot end without passing through the first air duct 110, and is blown out from the heat dissipation air outlet 102, and no air is blown out from the housing air outlet 101. That is, the portable temperature regulating device 1 does not have a blowing function and only has a refrigerating function. At this time, the fan 400 is, for example, only used as a cooling fan for the refrigerating sheet 200. Referring to Figure 4, for example, an air duct bracket 130 is provided inside the housing 100, and the two sides of the air duct bracket 130 respectively form the first air duct 110 and the second air duct 120 with the housing 100. For example, when the air duct baffle 300 is located at the second position 121, since the air duct baffle 300 cannot completely block the second air duct 120 at the second position 121, at this time, a part of the airflow generated by the fan 400 is discharged from the housing air outlet 101 through the first air duct 110, and another part of the airflow generated by the fan 400 passes through the second air duct 120 to the hot end to dissipate heat from the hot end. That is, the airflow generated by the fan 400 is divided into two parts. One part is used to dissipate heat from the cooling fin 200, and the other part is blown out from the housing air outlet 101 to cool the user. At this time, the portable temperature control device 1 has both a blowing function and a refrigerating function. The fan 400 is, for example, a cooling fan for the cooling fin 200 and a cooling fan capable of blowing air to the user.

[0037] The portable temperature control device provided in this embodiment can only refrigerate when the air duct baffle 300 is located at the first position 111 and can refrigerate and blow air when the air duct baffle 300 is located at the second position 121 by providing an air duct baffle 300 with a selectable position. The portable temperature control device 1 has two freely selectable temperature control methods, so as to meet various different needs of users.

[0038] Furthermore, referring to Figure 5 , the portable temperature control device 10 further includes, for example, a driving component 500. The driving component 500 is, for example, arranged inside the housing 100 and connected to one end of the air duct baffle 300. The other end of the air duct baffle 300 can move under the drive of the driving component 500. For example, the driving component 500 is a structure that can drive the air duct baffle 300 to move, and the present application does not specifically limit this.

[0039] Continuing from the above, referring to Figure 6 , the air duct baffle 300 includes, for example, a free end 320 and a rotating shaft end 310 arranged opposite to each other. The rotating shaft end 310 is, for example, arranged on the housing 100. For example, a fixing plate or a support plate is arranged on the housing 100, and the rotating shaft end 310 is, for example, arranged on the fixing plate or the support plate. For example, the rotating shaft end 310 has a columnar rotating shaft structure, and the rotating shaft end 310 has the same effect as the rotating shaft. Specifically, the rotating shaft end 310 is, for example, arranged on the air duct bracket 130. The driving component 500 is, for example, connected to the rotating shaft end 310, and the free end 320 can rotate around the rotating shaft end 310 under the drive of the driving component 500. Specifically, the driving component 500 drives the rotating end 310 to rotate, and further, the free end 320 can rotate around the rotating shaft end 310 under the rotation of the rotating end 310.

[0040] In a specific embodiment, referring again to Figure 6 , the driving assembly 500 includes, for example, a driving member 510 and a first gear 520, and the first gear 520 is connected to the rotating shaft end 310. A second gear 511 is, for example, provided on the driving member 510, and the first gear 520 meshes with the second gear 511. For example, the driving member 510 is a motor. By driving the rotation between the first gear 520 and the second gear 511 by the motor, the rotating shaft end 310 connected to the first gear is driven to rotate, and thus the free end 320 can be switched between the first position 111 and the second position 121 under the rotation of the rotating shaft end 310.

[0041] In addition, referring to Figure 3 , the air duct baffle 300 is also selectively arranged at the third position 122. For example, the third position 122 is close to the refrigerating member 200. When the air duct baffle 300 is located at the third position 122, the air duct baffle 300 closes the second air duct 120 so that the air flow generated by the fan 400 is discharged through the first air duct 110 to the housing air outlet 101. Specifically, when the air duct baffle 300 is arranged at the third position 122, the air duct baffle 300 can completely block the second air duct 120. At this time, the air flow generated by the fan 400 is only discharged through the first air duct 110 to the housing air outlet 101 without passing through the second air duct 120 to dissipate heat from the refrigerating sheet 200, that is, the portable temperature regulating device 1 does not have a refrigerating function and only has a blowing function. At this time, the fan 400 only serves as a cooling fan for blowing air to cool the user. It should be noted that when the air duct baffle 300 is arranged at the third position 122, since the air flow blown by the fan 400 does not pass through the hot end of the refrigerating sheet 200 and thus cannot dissipate heat from the hot end, it is necessary to turn off the refrigerating sheet 200 to avoid damage to the refrigerating sheet 200 caused by the too high temperature of the hot end.

[0042] In another specific embodiment, referring to Figure 7 and Figure 8, the driving assembly 500 includes, for example, a magnetic driving member 530 and a connecting member 540. One end of the connecting member 540 is connected to the rotating shaft end 310, and the other end is connected to the magnetic driving member 530. The connecting member 540 is connected to the driving end of the magnetic driving member 530, for example. The magnetic motor 530 further includes an elastic reset member 550 sleeved on the driving end of the magnetic driving member 530. For example, when the magnetic driving member 530 is energized, it adsorbs and drives the connecting member 540 to move away from the air duct baffle 300. Then, the connecting member 540 drives the rotating end 310 to rotate, and the elastic reset member 550 is compressed. When the magnetic driving member 530 is de-energized, it does not adsorb, and the driving end of the magnetic driving member 530 can be reset under the elastic action of the elastic reset member 550, thereby driving the connecting member 540 to move towards the air duct baffle 300 and further driving the rotating end 310 to rotate.

[0043] In addition, a circuit board is provided in the housing 100. A main control switch is provided on the circuit board. The driving assembly, the fan, and the refrigerating member are respectively electrically connected to the circuit board. The main control switch is used to control the working states of the fan, the refrigerating member, and / or the driving assembly.

[0044] In addition, referring again to Figure 2 and Figure 5 , the portable temperature regulating device 10 further includes a heat dissipating member 600 and a heat conducting member 700. The heat dissipating member 600 is disposed in the second air duct 120 and is thermally conductively connected to the hot end, for example. The heat conducting member 700 is disposed on the housing 100 and is thermally conductively connected to the cold end. The side of the heat conducting member 700 away from the refrigerating member 200 faces the neck wearing space 40, or the heat conducting member 700 is exposed outside the housing 100. For example, the heat dissipating member 600 mentioned above is a heat dissipating fin, and the heat conducting member 700 mentioned above is a metal heat conducting member, which can be a heat conducting aluminum sheet, for example. The heat conducting member 220 can also be a heat conducting silicone, for example. The present application does not limit this. It should be noted that the above-mentioned "thermally conductively connected" means that heat transfer can be formed by direct contact or indirect contact between two objects. For example, heat transfer can be formed by indirect contact through an intermediate heat conducting medium such as thermal grease / silicone or graphite. By providing the heat dissipating member 600, the heat dissipation efficiency of the refrigerating sheet 200 is improved, and thus the refrigerating efficiency of the refrigerating sheet 200 is improved. By providing the heat conducting member 700, the heat conduction efficiency of the refrigerating sheet 200 is improved.

[0045] Continuing from the above, referring again to Figure 5, a heat dissipation air outlet 102 is further provided on the housing 100, and the second air duct 120 communicates with the heat dissipation air outlet 102. When the air duct baffle 300 is disposed at the first position 111, the airflow generated by the fan 400 passes through the second air duct 120 to the heat dissipation member 600 and is discharged from the heat dissipation air outlet 102; when the air duct baffle 300 is disposed at the second position 121, the first airflow generated by the fan 400 is discharged from the housing air outlet 101 through the first air duct 110, and the second airflow generated by the fan 400 passes through the second air duct 120 to the heat dissipation member 600 and is discharged from the heat dissipation air outlet 102.

[0046] It should be noted that the above-mentioned air duct baffle 300 and the first air duct 110 and the second air duct 120 are all disposed, for example, in the first wearing arm 10, the second wearing arm 20 and / or the wearing bracket 30. For example, the above-mentioned structures are all disposed in the first wearing arm 10. It can be understood that the second wearing arm 20 has, for example, the same structure as the first wearing arm 10 to further improve the temperature regulation effect. Of course, the above-mentioned structure can also be disposed only in the first wearing arm 10, and the present application does not specifically limit this. That is, the internal structure of the first wearing arm 10 and the internal structure of the second wearing arm 20 can be the same or different. Preferably, the second wearing arm 20 has the same above-mentioned structure as the first wearing arm 10. And, the wearing bracket 30 also has, for example, the same structure as the first wearing arm 10 to further improve the temperature regulation effect. Of course, the above-mentioned structure can also be disposed only in the wearing bracket 30, and the present application does not specifically limit this. That is, the internal structure of the wearing bracket 30 and the internal structure of the first wearing arm 10 can be the same or different. Preferably, the wearing bracket 30 has the same above-mentioned structure as the first wearing arm 10.

[0047] In summary, the portable temperature regulation device provided by the embodiment of the present invention has two freely selectable temperature regulation methods by setting an air duct baffle with a switchable position, so that when the air duct baffle is in the first position, the portable temperature regulation device only cools, and when the air duct baffle is in the second position, the portable temperature regulation device can cool and blow air at the same time, thus meeting various different needs of users.

[0048] It can be understood that the foregoing embodiments are only exemplary descriptions of the present invention. On the premise that the technical features do not conflict, the structures do not contradict, and the invention purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
