Technical Field

[0001] This utility model relates to the field of neck pillow technology, and in particular to a novel hot and cold neck pillow. Background Technology

[0002] A Chinese utility model patent, published on October 17, 2023, with publication number CN219836045U, describes a shoulder-hugging U-shaped neck pillow. Through the design of Velcro A, Velcro B, and a self-heating pulse electrode, an automatic heating and electromagnetic pulse structure can be conveniently established on the inner arc surface and bottom of the U-shaped neck pillow. When the user uses the U-shaped neck pillow, it facilitates electromagnetic pulse therapy on the user's neck muscles, allowing for better relief and relaxation of the neck muscles. It also provides some heat in cold environments, effectively improving the user's comfort and sleep quality.

[0003] However, this neck pillow only has a heating function and no cooling function, making it limited in function and unable to meet people's different needs. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of hot and cold neck pillow to solve the problem that the existing neck pillows only have a heating function and no cooling function, which is a single function and cannot meet people's different needs.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel hot and cold neck pillow, comprising an outer shell, the outer shell having an accommodating space, the outer shell including a fitting plate that fits against the neck and a back plate facing away from the neck, the back plate having several air holes on its surface, and the neck pillow further comprising:

[0006] A heating and cooling assembly is disposed within an accommodating space. The heating and cooling assembly includes a temperature-conducting element, a semiconductor cooling chip, a heat sink, and a fan arranged sequentially from a bonding plate to a back plate. The temperature-conducting element is attached to the bonding plate, and the heat sink has several airflow channels.

[0007] At least one air guide is provided within the accommodating space, which divides the accommodating space into an air inlet area and an air outlet area. Both the air inlet area and the air outlet area are connected to the air intake channel. The air inlet is connected to the air inlet area and the air outlet is connected to the air outlet area.

[0008] Preferably, the outer shell is U-shaped and includes a first shell and a second shell. Both ends of the first shell are provided with flexible tubes. One end of the flexible tube is fixedly connected to the second shell. There is a gap between the first shell and the second shell. A silicone shell is provided between the first shell and the second shell. The silicone shell covers the gap and is sleeved around the flexible tube.

[0009] Preferably, there are two air guides and two air outlet areas. The air guides are symmetrically arranged on both sides of the heat sink. The air guide is a frame plate with two openings. One opening is fitted to the back plate, and the other opening is connected to the air intake channel.

[0010] Preferably, the fan is fixedly connected to the frame, and the air guide, the frame, and the heat sink are detachably and fixedly connected.

[0011] Preferably, the heating and cooling components are detachably and fixedly connected within the accommodating space. At least one threaded post is provided within the accommodating space.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0022] like Figures 1-3 As shown, this utility model provides a novel hot and cold neck pillow, including a shell 1, which has an accommodating space inside. The shell 1 includes a fitting plate 111 that fits against the neck and a back plate 112 that faces away from the neck. Several air holes are opened on the surface of the back plate 112. The neck pillow also includes a hot and cold component 2 and at least one air guide 3.

[0023] The heating and cooling component 2 is located within the accommodating space. The heating and cooling component 2 includes a heat-conducting element 22 (which can be a copper sheet), a semiconductor cooling chip 21 (the characteristic of the semiconductor cooling chip 21 is that it can quickly cool when the positive and negative polarities are connected when the input power supply voltage is applied, and can quickly heat when the polarities are reversed; this is also an existing technology, and the specific principle will not be elaborated here. Thus, when the semiconductor cooling chip 21 is cooling or heating, its temperature is transferred through the heat-conducting element 22 to apply cold and hot compresses to the neck), a heat sink 23, and a fan 24 (an intake fan 24 is used here, and the intake fan 24 is located in the intake area). The heat-conducting element 22 is attached to the bonding plate 111, and the heat sink 23 has several air-guiding channels.

[0024] The air guide 3 is located in the accommodating space. The air guide 3 divides the accommodating space into an air inlet area and an air outlet area. Both the air inlet area and the air outlet area are connected to the air duct. The air hole connected to the air inlet area is the air inlet 1121, and the air hole connected to the air outlet area is the air outlet 1122.

[0025] When the neck pillow is used for cold compress, the thermoelectric cooler 21 is controlled to cool. The surface of the thermoelectric cooler 21 that is in contact with the heat-conducting component 22 is the cold end, and the surface that is in contact with the heat sink 23 is the hot end. The temperature difference between the cold end and the hot end is large. Therefore, the hot end of the thermoelectric cooler 21 needs to be actively cooled by the fan 24 and the heat sink 23 to reduce the temperature of the hot end. The temperature of the cold end will also decrease accordingly, thereby achieving a lower temperature and providing better cold compress for the neck. (Specifically, the cold air outside the outer shell 1 enters the air intake area through the air inlet 1121 of the outer shell 1 and then passes through the fan 24 and the heat sink 23 to cool the thermoelectric cooler 21. The heat dissipated by the fan 24 and the heat sink 23 enters the air outlet area through the air intake channel and is finally dissipated from the air outlet 1122, thereby reducing the temperature of the hot end of the thermoelectric cooler 21.)

[0026] When the neck pillow is used for heat therapy, the semiconductor cooling chip 21 is controlled to generate heat. At this time, the fan 24 and heat sink 23 are not working, and the heat conduction component 22 provides heat therapy to the neck. Thus, the neck pillow can have both heating and cooling functions at the same time, making it more versatile and able to meet different needs.

[0027] like Figure 4 As shown, the outer shell 1 is U-shaped and includes a first shell 11 and a second shell 12. Both ends of the first shell 11 are provided with flexible tubes 6 (here, the flexible tube 6 is a corrugated tube, which can be bent and shaped). One end of the flexible tube 6 is fixedly connected to the second shell 12. There is a gap between the first shell 11 and the second shell 12. A silicone shell 5 is provided between the first shell 11 and the second shell 12. The silicone shell 5 covers the gap and is sleeved around the flexible tube 6.

[0028] By incorporating a flexible and shape-adjustable tube 6, the distance between the two second housings 12 can be adjusted and shaped, allowing the neck pillow to be adapted to people with different neck sizes. This avoids the problems of traditional neck pillows having a fixed opening size, which can cause a feeling of tightness when worn by people with large necks and easily fall off when worn by people with small necks.

[0029] like Figure 2 and Figure 3 As shown, there are two air guides 3 and two air outlet areas. The air guides 3 are symmetrically arranged on both sides of the heat sink 23. The air guide 3 is a frame plate with two openings. One opening is attached to the back plate 112, and the other opening is connected to the air intake channel. Figure 2 The middle arrow indicates the direction of gas flow;

[0030] By using the two frame plates in this way, the heat dissipated by the fan 24 and the heat sink 23 can be ensured to enter the air outlet area through the air intake channel and finally be dissipated from the air outlet 1122, thereby reducing the hot end temperature of the semiconductor cooling chip 21. The air duct design with air intake in the middle and air outlet on both sides increases the airflow through the heat sink 23, accelerates the heat exchange efficiency, and dissipates heat faster.

[0031] like Figure 2 and Figure 3 As shown, the fan 24 is fixedly connected to the frame 4, and the air guide 3, the frame 4 and the heat sink 23 are detachably fixedly connected.

[0032] The frame 4 can support the fan 24. By setting a detachable fixed connection between the air guide 3, the frame 4 and the heat sink 23, it is convenient to disassemble, repair or replace a component when it is damaged.

[0033] Specifically, the heating and cooling component 2 is detachably and fixedly connected to the accommodating space. At least one threaded post 1111 is provided in the accommodating space. The threaded post 1111 is fixed to the bonding plate 111 and passes through the heat sink 23. The air guide 3 and the frame 4 are respectively provided with a first horizontal plate 31 and a second horizontal plate 41 on the opposite side. The first horizontal plate 31, the second horizontal plate 41 and the threaded post 1111 are fixed together by screws. The heat sink 23 is a heat sink fin. The bottom surface of the first horizontal plate 31 or the second horizontal plate 41 is attached to the top surface of the heat sink fin. The two sides of the semiconductor cooling chip 21 are fixedly attached to the heat sink 23 and the temperature conducting component 22 respectively.

[0034] Here, we take the example of the second horizontal plate 41 being attached to the top surface of the heat sink fins as an example: the heat sink 23 can be positioned by passing through the threaded post 1111. Screws are used to pass through the first horizontal plate 31 and the second horizontal plate 41 in sequence and enter the threaded post 1111, thereby completing the fixation of the first horizontal plate 31, the second horizontal plate 41 and the heat sink 23, which facilitates the assembly and disassembly of the air guide 3, the frame 4 and the heat sink 23.

[0035] It should be noted that the threaded post 1111 can also penetrate the first horizontal plate 31 and the second horizontal plate 41. The top of the threaded post 1111 is flush with the top surface of the first horizontal plate 31. At this time, the first horizontal plate 31 and the second horizontal plate 41 can be quickly positioned, thereby completing the rapid fixation between the first horizontal plate 31, the second horizontal plate 41 and the heat sink 23.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
