Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a semiconductor refrigeration component. Background Art

[0002] The invention of the air conditioner has greatly improved people's lives, but the air conditioner is only suitable for use in relatively closed spaces, and cannot be used outdoors or in some special occasions, such as die-casting workshops, heat treatment workshops, etc. This makes the working environment of people working in the above occasions harsh. The high temperature and high cold environment will seriously endanger human health and easily cause work errors.

[0003] In order to improve the comfort of workers in the above environment, a contact semiconductor refrigeration air-conditioning suit is disclosed in the patent document with the announcement number CN215873526U. The scheme discloses a refrigeration unit, which includes an outer shell, an inner shell, a fan, a semiconductor refrigeration sheet and a cooling shell. The outer shell is connected to the inner shell, and the fan and the semiconductor refrigeration sheet are arranged between the outer shell and the inner shell. The cooling shell is fixed on the inner shell near the inner side of the clothing body. The outer shell is provided with an air outlet and the inner shell is provided with an air inlet. The control unit is connected with a wiring harness and connected to the refrigeration unit through the wiring harness. The scheme adopts semiconductor temperature control technology to achieve good body-sensing cooling effect and is comfortable and convenient to wear.

[0004] The structure of the refrigeration unit of this scheme is that the cooling shell contacts the human body, the refrigeration unit clamps the clothing body through the fixing ring and the inner shell, the air inlet channel of the radiator is on the inner shell, and the exhaust channel of the radiator is on the outer shell. It can be seen from the specification and the drawings of the specification that the distance from the clothing body to the cooling shell is large. In this way, after the refrigeration unit is assembled on the clothing body and then worn on the body, the refrigeration component will hold the clothing body very high, and the air-conditioned clothing will appear bloated when worn on the body, affecting the appearance. In addition, the air inlet channel of the radiator of this scheme is on the inner shell, and the cooling shell is also fixed on the inner shell. In this design, the airflow formed when the fan is working will take away the cold of the cooling shell, greatly reducing the refrigeration effect. In addition, since there is no anti-slip device on the inner shell, relative movement will occur between the clothing body and the inner shell when the refrigeration component is installed, which is easy to cause the clothing body to deform and the installation position of the refrigeration component to be uncertain; the fixing ring of this scheme is a circular ring structure, and no anti-slip structure is set. Therefore, when the fixing ring is rotated for tightening, it is not easy to tighten the fixing ring on the inner shell, so that the refrigeration unit is easy to fall off from the clothing body.

[0005] Therefore, it is necessary to invent a refrigeration assembly with a simple structure, anti-slip during installation and the ability to easily tighten the fixing ring on the inner shell to solve the above problems. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the utility model provides a semiconductor refrigeration component. By changing the structural design and simplifying the structure, the distance between the refrigeration component and the installation point of the clothing body to the human body is shortened, thereby making the air-conditioned clothing more close-fitting and beautiful. In addition, an anti-slip structure is provided to facilitate installation and prevent the refrigeration component from falling off the clothing body.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a semiconductor refrigeration component, including a shell, the shell including a main frame and a mesh cover and a fastener detachably mounted on the main frame; the main frame includes a first extension portion with a circular cross-section, and a first stop portion extending radially outward is provided at one end of the first extension portion; a surface cover is provided at the end outside the first extension portion; a refrigeration component mounting portion and a radiator mounting portion are provided inside the first extension portion; an air inlet hole and an exhaust hole are provided on the mesh cover, and the mesh cover is installed on the side of the first stop portion away from the surface cover; an anti-slip protrusion is provided on the side of the stop portion close to the surface cover; the fastener has a second extension portion, and a second stop portion extending radially outward is provided at one end of the second extension portion; more than two anti-slip portions are arranged in an array on the outer edges of the first stop portion and the second stop portion; more than two anti-slip ribs are provided between the second extension portion and the second stop portion.

[0008] In the above scheme, the mesh cover is separately arranged on the shell, and the face cover is arranged on the other side of the mesh cover relative to the main frame, and the face cover is in contact with the human body. In this way, the main frame is used to be connected to the clothing body, and the distance between the clothing body and the human body is greatly reduced. When the clothing is worn on the human body, the refrigeration component will not prop up the clothing, thereby improving the aesthetic effect; the air inlet and exhaust holes are arranged on the mesh cover at the same time to prevent the fan from taking away the cold generated by the refrigeration plate; an anti-skid protrusion is arranged on the side of the resisting part close to the face cover. Since the refrigeration component is connected to the power cord, when the fastener is tightened, the air-conditioning clothing body will not rotate with the rotation of the fastener, so that the refrigeration component can be quickly installed in the correct position to avoid the power cord facing an inappropriate position; more than two anti-skid ribs are arranged between the second extending part and the second resisting part, and the anti-skid ribs can increase the friction when the fastener is rotated to prevent the fastener from being reliably tightened on the main frame due to slipping, thereby preventing the refrigeration component from falling off from the clothing body.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figures 1 to 7 As shown, a semiconductor refrigeration component includes a shell, which includes a main frame 1 and a mesh cover 2, a fastener 3 and a surface cover 7 detachably mounted on the main frame.

[0018] like Figure 6 As shown, the main frame 1 includes a first extending portion 10 with a circular cross-section, and a first blocking portion 11 extending outward is provided at one end of the first extending portion 10. The cross-sectional area of ​​the first blocking portion 11 is larger than the cross-sectional area of ​​the first extending portion 10. When installed, the first extending portion 10 passes through a through hole opened on the air-conditioning clothing body, and the first blocking portion 11 abuts against one side of the through hole.

[0019] like Figure 5 As shown, a refrigeration component mounting portion 12 and a radiator mounting portion 13 are provided inside the first extending portion 10 , a refrigeration fin 4 is provided on the refrigeration component mounting portion 12 , and a radiator 5 is provided on the radiator mounting portion 13 .

[0020] The refrigeration assembly mounting portion 12 includes a stopper 121 extending from the inner wall of the first extension portion 10 toward the center, and the stopper 121 encloses a refrigeration fin accommodating cavity 122 that can accommodate the refrigeration fin 4. The refrigeration fin 4 is transitionally matched with the refrigeration fin accommodating cavity 122. Usually, the refrigeration fin 4 is made into a rectangular shape, so the refrigeration fin accommodating cavity 122 is formed into a rectangular shape.

[0021] In order to enhance the strength of the limiting block 121 and increase the contact area between the cooling fin accommodating cavity 122 and the cooling fin 4 , a reinforcing rib 123 is further provided between the limiting block 121 and the first extending portion 10 .

[0022] like Figure 2As shown, a non-slip protrusion 110 is provided on one side of the first stopper 11 close to the cover 7. Since the refrigeration components are connected to power lines, after the non-slip protrusion 110 is provided, when the fastener 3 is tightened, the air-conditioning clothing body will not rotate with the rotation of the fastener 3, so that the refrigeration component can be quickly installed in the correct position, avoiding the power line facing an inappropriate position, and facilitating installation.

[0023] like Figure 5 As shown, the radiator mounting portion 13 includes more than two radiator limiting columns 124 extending from the limiting block 121 toward the first stop portion 11; in order to enhance the strength of the radiator limiting columns 124, a second reinforcing rib is also provided between the radiator limiting columns 124 and the inner wall of the first extension portion 10, and the second reinforcing rib extends to the limiting block 121.

[0024] The radiator 5 is provided with a mounting hole 50 that matches the radiator limiting column 124; during installation, the mounting hole 50 of the radiator is passed through the radiator limiting column 124, and the end surface of the radiator limiting column 124 contacts the limiting block 121. Usually, the radiator 5 is made of aluminum profiles, and in order to reduce the weight of the radiator 5 and improve the heat dissipation efficiency, a concave cavity 51 is milled out of the center of the radiator 5.

[0025] like Figure 5 As shown, more than two first fan limiting posts 14 are provided inside the first extension portion 10 . The first fan limiting posts 14 are used to prevent the fan bracket from rotating. A fan 6 is provided between the first fan limiting posts 14 .

[0026] In the present embodiment, the number of the first fan limiting columns 14 is four, which are divided into two large and two small ones. The two large first fan limiting columns 14 are provided with limiting grooves 140 toward the center of the first extension portion 10, and the limiting grooves 140 are used to accommodate the bracket of the fan 6. The two small first fan limiting columns 14 block the bracket of the fan 6 from both sides to prevent the fan 6 from rotating as a whole.

[0027] like Figure 7 As shown, in order to further improve the positioning accuracy of the fan 6, more than two second fan limiting columns 21 for radial limiting the fan 6 are provided on the inner wall of the mesh cover 2; in this embodiment, the number of the second fan limiting columns 21 is six.

[0028] like Figure 1 and Figure 3 As shown, the mesh cover 2 is installed on the side of the first blocking portion 11 away from the surface cover 7 .

[0029] like Figure 7 As shown, the mesh cover 2 is a U-shaped structure, and includes a bottom wall 22 and a side wall 23 . An exhaust hole 220 is opened on the bottom wall 22 ; and an air inlet hole 230 is opened on the side wall 23 .

[0030] like Figure 3 As shown, the lowest position of the blade 60 of the fan 6 is higher than the lowest position of the air inlet 230 .

[0031] The exhaust hole 220 and the air inlet hole 230 are arranged on the same side of the clothing body. In the above structure, the exhaust hole 220 and the air inlet hole 230 can be integrally formed with the mesh cover by injection molding, which can prevent the fan 6 from taking away the cold energy generated by the refrigeration plate 4, and can also simplify the structure of the refrigeration component and reduce costs.

[0032] like Figure 6 and Figure 7 As shown, more than two locking screw columns 231 are provided on the inner side of the side wall 23; a locking screw hole 112 corresponding to the locking screw column 231 is provided on the first retaining portion 11; a positioning boss 232 which can be inserted into the groove 113 on the end face of the first retaining portion 11 is also provided on the end face of the side wall 23, and the positioning boss 232 is arranged along the circumferential direction.

[0033] When installing the net cover 2, the positioning boss 232 is inserted into the groove 113, and the locking screw column 231 is aligned with the locking screw hole 112, and then the screw is tightened. The operation is simple and the installation is reliable.

[0034] The side wall 23 of the mesh cover 2 is also provided with a power line passing hole 233 .

[0035] like Figure 3 and Figure 7 As shown, an axial limiting boss 234 for axially limiting the fan 6 is provided inside the bottom wall 22 of the mesh cover 2. When the mesh cover 2 is installed, the axial limiting boss 234 will support the end surface of the fan 6.

[0036] like Figure 3 and Figure 4 As shown, the fastener 3 has a second protruding portion 31 , and a second blocking portion 32 extending outward is provided at one end of the second protruding portion 31 .

[0037] like Figure 2 As shown, more than two anti-skid portions 115 are arranged in an array on the outer edges of the first stop portion 11 and the second stop portion 32. In this embodiment, the anti-skid portions 115 are arc-shaped, eight in number, and evenly distributed on the outer edges of the first stop portion 11 and the second stop portion 32. The anti-skid portions 115 can effectively prevent skidding when installing the refrigeration assembly.

[0038] like Figure 1 and Figure 3 As shown, more than two anti-slip ribs 33 are provided between the second protruding portion 31 and the second resisting portion 32 .

[0039] The anti-skid ribs 33 can increase the friction between the hand and the fastener 3 when rotating the fastener 3, preventing the fastener 3 from being reliably tightened on the main frame 1 due to slipping, thereby preventing the refrigeration component from falling off the clothing body.

[0040] like Figure 4 and Figure 6 As shown, an external thread 102 is provided on the outside of the first extending portion 10 , and an internal thread 302 is provided on the inside of the second extending portion 31 , and the internal thread 302 cooperates with the external thread 102 .

[0041] In this embodiment, the external thread 102 is a trapezoidal thread, and the external thread 102 is evenly distributed on the outer circumference of the first extension portion 10 in three sections, and the internal thread 302 is evenly distributed inside the second extension portion 31 in two sections to reduce friction during screwing.

[0042] The main frame 1, the mesh cover 2 and the fastener 3 are all made of plastic injection molding. In this embodiment,

[0043] The main frame 1, the mesh cover 2 and the fastener 3 can be made of injection molding of materials such as ABS, nylon or nylon plus fiber.

[0044] like Figure 1 and Figure 3 As shown, the cover 7 is arranged at the end outside the first extension portion 10 .

[0045] like Figure 6 As shown, a face cover mounting portion 103 having an outer diameter smaller than that of the first extending portion 10 is provided at the outer end of the first extending portion 10, and more than three mounting bosses 104 are provided on the outer peripheral surface of the face cover mounting portion 103, and the mounting bosses 104 extend along the axial direction of the face cover 7 mounting portion, and a chamfer is provided at one end of the mounting boss 104 close to the end of the first extending portion 10, and the face cover 7 is fixed to the first extending portion 10 through the mounting bosses 104.

[0046] Usually, the mounting boss 104 is designed to be arc-shaped, and the face cover 7 is usually stamped from a stainless steel sheet. The face cover 7 and the mounting boss 104 form an interference fit. To ensure the reliability of the connection, glue can be applied between the face cover 7 and the face cover mounting portion 103, or a chamfer can be provided at one end of the mounting boss 104 close to the first stop portion 11. After the face cover 7 is put on the mounting boss 104, the end of the face cover 7 is bent toward the chamfer to form a barb to prevent the face cover 7 from falling off the first protruding portion 10.

[0047] In order to make the cooling fins 4 and the surface cover 7 closely connected and improve the effect of cold transfer, silicone grease is coated between the cooling fins 4 and the surface cover 7.

[0048] The refrigeration assembly further includes a power cord (not shown) and a PCB board 8. The power cord, the refrigeration plate 4 and the fan 6 are all electrically connected to the PCB board 8. A connector and a control switch are also provided on the power cord.

[0049] The cooling sheet 4 can switch the direction of the cooling surface and the heating surface by switching the polarity of the positive and negative electrodes. When it is necessary to switch from cold compress to hot compress, it can be switched by controlling the switch.

[0050] When the refrigeration component is installed on the air-conditioning clothing body, the first extension part 10 is first passed through the installation hole on the air-conditioning clothing body, and then the fastener 3 is tightened on the main frame 1. After installation, the distance between the air-conditioning clothing body and the face cover 7 is short. Therefore, when the clothes are worn on the human body, the refrigeration component will not prop up the clothes, thereby improving the aesthetic effect. In this scheme, the mesh cover 2 is arranged at the end away from the face cover 7, and the exhaust hole 220 and the air inlet hole 230 are both arranged on the mesh cover 2. The exhaust hole 220 and the air inlet hole 230 are arranged on the outer side of the clothing body. The above structure can prevent the fan 6 from taking away the cold generated by the refrigeration plate 4, which can simplify the structure of the refrigeration component and reduce the cost.

[0051] After the anti-skid protrusion 110 is provided, when the fastener 3 is tightened, the air-conditioning clothing body will not rotate with the rotation of the fastener 3, so that the refrigeration component can be quickly installed in the correct position, avoiding the power cord from being directed to an inappropriate position, and facilitating installation; the anti-skid rib 33 can increase the friction between the hand and the fastener 3 when rotating the fastener 3, preventing the fastener 3 from being reliably tightened on the main frame 1 due to slipping, thereby preventing the refrigeration component from falling off the clothing body.
