Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, in particular to a seat cushion. Background Art

[0002] In modern home and office environments, people have increasingly higher requirements for the comfort of seats. However, common chairs on the market often have some design flaws, such as the seat surface is too hard or lacks sufficient softness, which may make people feel uncomfortable after long-term use, and even affect their health. In order to solve this problem, many people choose to buy cushions to improve the comfort of the seats. However, although the existing cushions have increased the softness to a certain extent, they still have some deficiencies in functionality. In the hot summer, due to the limitations of the cushion material, they often do not have good breathability. Long-term use will make people feel stuffy and even sweat, which will undoubtedly reduce the user's comfort and work efficiency. Or in the cold winter, the cushion faces the problem of insufficient warmth, which is also inconvenient. Utility Model Content

[0011] The beneficial effects of the present invention are: the present invention provides a seat cushion, compared with the existing technology, the present invention has at least the following technical effects: 1. By opening a accommodating cavity between the upper gasket and the lower gasket, the accommodating cavity can be filled with liquid, and the filled liquid can be a special cooling liquid or a special heating liquid. Filling with different liquids can be used as a summer version and a winter version, respectively, which are suitable for scenes that need cooling in summer and scenes that need heating in winter, and each accommodating cavity is independent of each other and cannot be connected. Therefore, the liquid in each accommodating cavity is independent of each other and will not transfer heat to each other. Compared with all liquids being contained in one chamber, the heat transfer efficiency is lower, and it can have a more lasting thermal insulation effect, providing users with a more lasting cold source and heat source, and increasing the comfort when sitting; there are gaps between adjacent accommodating cavities, which can play a role in ventilation and air permeability, thereby improving comfort. 2. The accommodating cavity protrudes from the surface of the upper gasket and the lower gasket at the same time, so that a breathable gap can be formed between adjacent accommodating cavities, that is, there are breathable gaps on both the upper and lower surfaces, which can maximize the breathability of the cushion and provide suitable temperature and comfort in both summer and winter. 3. The protruding height of the accommodating cavity in contact with the buttocks of the human body is lower than the protruding height of the other accommodating cavities to adapt to the curve of the human body. On the one hand, it can reduce the pressure on the buttocks and increase the comfort of sitting for a long time. On the other hand, it can also increase the contact surface with other parts such as the thighs to provide a certain amount of heat or cooling. If there is no such design, the cushion may only have greater skin contact at the buttocks and pelvis, while the rest of the parts may not have contact or the release area is small, which cannot play the role of cooling and providing heat.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] See also Figures 1 to 2A seat cushion comprises an upper pad 1 and a lower pad 2. The upper pad 1 is fixed to the lower pad 2. A plurality of accommodating cavities 3 are formed between the lower pad 2 and the upper pad 1. Adjacent accommodating cavities 3 are independent of each other and have ventilation gaps 4 between adjacent accommodating cavities 3. The accommodating cavities 3 are filled with liquid. By forming the accommodating cavities 3 between the upper pad 1 and the lower pad 2, the accommodating cavities 3 can be filled with liquid. The liquid filled can be a cooling liquid or a heating liquid. Filling different liquids can provide a summer version and a winter version, respectively suitable for cooling in summer and heating in winter. Each accommodating cavity 3 is independent and cannot communicate with each other. Therefore, the liquid in each accommodating cavity 3 is independent of each other and does not transfer heat to each other. Compared with all liquids being contained in a single cavity, the heat transfer efficiency is lower, and the cushion can have a longer-lasting heat preservation effect, providing a longer-lasting cooling and heating source for the user, and improving the comfort of the user. The gaps 4 between adjacent accommodating cavities 3 can provide ventilation and air permeability, thereby improving the comfort. The cooling liquid may be, but is not limited to, a silicone coolant, a hydrocarbon coolant, etc. The heating liquid may be, but is not limited to, some heat transfer oil, or water, etc.

[0020] See also Figures 1 to 2 Preferably, the accommodating cavities 3 protrude from the upper surface of the upper gasket 1, and the gap 4 is located above the upper surface of the upper gasket 1. Since the accommodating cavities 3 are independent of each other, when they protrude from the surface of the upper gasket 1, a breathable gap 4 is naturally formed between the two accommodating cavities 3, which can enhance the breathability of the seat cushion, especially when used in summer, reducing the feeling of stuffiness and improving the user's comfort experience.

[0021] See also Figures 1 to 2 Preferably, the raised height of the accommodating cavity 3 in contact with the buttocks of the human body is lower than the raised height of the other accommodating cavities 3. This adapts to the curves of the human body. On the one hand, it can reduce the pressure on the buttocks and increase the comfort of sitting for a long time. On the other hand, it can also increase the contact surface with other parts of the body, such as the thighs, to provide a certain amount of heat or cooling. Without this design, the seat cushion may only have greater skin contact at the buttocks and pelvis, while the rest of the area has no contact or a small contact area, which cannot achieve the cooling and heat providing effects.

[0022] See also Figures 1 to 2 Preferably, the plurality of accommodating cavities 3 are arranged in a rectangular array to facilitate production and manufacturing.

[0023] See also Figures 1 to 2 Preferably, the cross section of the accommodating cavity 3 is circular or rectangular. Adjust according to actual needs.

[0024] See also Figures 1 to 2Preferably, the upper gasket 1 and the lower gasket 2 are made of flexible materials, preferably flexible ABS, TPU, PVC, HDPE, CPE, etc., but not limited thereto.

[0025] See also Figures 1 to 2 Preferably, a coat can also be applied to the cushion.

[0026] Example 2

[0027] See also Figures 3 and 4 This embodiment differs from the first embodiment in that the accommodating cavities 3 protrude from the upper surface of the upper gasket 1 and the lower surface of the lower gasket 2, and a gap 4 is defined between the upper side of the upper surface of the upper gasket 1 and the lower side of the lower surface of the lower gasket 2. The accommodating cavities 3 protrude from both the upper gasket 1 and the lower gasket 2, creating breathable gaps 4 between adjacent accommodating cavities 3. This means that breathable gaps 4 are present on both the upper and lower surfaces, maximizing the breathability of the seat cushion and ensuring a comfortable temperature and comfort in both summer and winter.

[0028] Example 3

[0029] The difference between this embodiment and the first embodiment is that the accommodating cavity 3 is protruded from the lower surface of the lower gasket 2, and the gap 4 is located on the lower side of the lower surface of the lower gasket 2. Protruding the accommodating cavity 3 from the lower surface of the lower gasket 2 and adjacent to each other helps to improve the air circulation between the cushion and the seat, further enhancing the heat dissipation effect. Figure 1 , but the structure of embodiment 1 is reversed.

[0030] The utility model has the following working principle:

[0031] The accommodating chamber 3 is filled with liquid. During production, it is filled with cooling liquid or heating liquid according to the summer version or winter version, which are respectively suitable for scenes requiring cooling in summer and heating in winter. Each accommodating chamber 3 is independent of each other and cannot be connected. Therefore, the liquid in each accommodating chamber 3 is independent of each other and will not transfer heat to each other. Compared with all liquids being contained in one chamber, the efficiency of heat transfer is lower, and it can have a more lasting heat preservation effect, providing a more lasting cold source and heat source for the user sitting there. For example, before use, the summer version can be placed in the refrigerator to cool down first and then used, while the winter version can be heated with hot water before use. There is a gap 4 between adjacent accommodating chambers 3, which can play a role in ventilation and improve comfort. During production, the upper gasket 1 is first turned upside down and then the accommodating chamber 3 is filled with liquid, and then the lower gasket 2 is fitted with the upper gasket 1.
