Description

Technical Field

[0001] The utility model relates to the field of seat cushions, in particular to a silica gel seat cushion with a heating function. Background Art

[0002] Silicone seat cushion is a seat cushion made of silicone material. Because of its good elasticity, breathability and high temperature resistance, it is widely used in scenes such as office chairs and car seats.

[0003] Some silicone seat cushions also feature heating to enhance user comfort. However, because the heating element is typically located directly inside the silicone seat cushion, when a user sits down, the pressure exerted by their buttocks on the surface of the silicone seat cushion causes it to move downward, squeezing the heating element and causing it to deform or damage. This can cause the silicone seat cushion to lose its heating function, severely impacting the user experience. Utility Model Content

[0004] Based on this, it is necessary to provide a silicone seat cushion with a heating function to solve the technical problems existing in the above background technology.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3 As shown, a silicone seat cushion with a heating function includes: a first silicone layer 10 and a second silicone layer 20, the first silicone layer 10 is located above the second silicone layer 20 and connected to the second silicone layer 20, the first silicone layer 10 is provided with a plurality of buffer cavities 11 spaced apart, the vertical cross-section of the first silicone layer 10 is wavy, the buffer cavity 11 is located on the side of the first silicone layer 10 close to the second silicone layer 20, and the second silicone layer 20 is provided with a plurality of heating elements 30, each of the heating elements 30 is located in one of the buffer cavities 11.

[0023] Specifically, when in use, the user sits on the silicone cushion, and the pressure exerted by the user's buttocks causes the outer surface of the first silicone layer 10 to move downward. Since the vertical cross-section of the first silicone layer 10 is wavy, the buffer cavity 11 can provide sufficient downward movement space for the outer surface of the first silicone layer 10, thereby reducing the pressure exerted by the outer surface of the first silicone layer 10 on the heating element 30, thereby preventing the heating element 30 on the second silicone layer 20 from being crushed when the user sits down. It should be noted that the heating element 30 is an electric heater. Since the electric heater is a common structure used by those skilled in the art, its working principle and structure will not be described in detail.

[0024] In one embodiment, Figure 2 As shown, a plurality of placement cavities 21 are provided on the second silicone layer 20, and each of the heating elements 30 is located in one of the placement cavities 21. Specifically, the depth of the placement cavity 21 is adapted to the height of the heating element 30, so that the surface of the heating element 30 placed in the placement cavity 21 is flush with the surface of the second silicone layer 20, thereby enhancing the comfort of the user when sitting on the silicone pad.

[0025] In one embodiment, the heating elements 30 are connected in series to form an electrical connection, so that only one power supply is needed to drive the heating elements 30 to work.

[0026] In one embodiment, an insulating layer is provided on each of the heating elements 30. Specifically, the insulating layer is made of alumina. Since alumina is resistant to high temperatures and is insulating, the insulating layer made of alumina can ensure the normal operation of the heating element 30 while also improving the safety of the user.

[0027] In one embodiment, Figure 2 and Figure 4 As shown, the silicone seat cushion with heating function also includes: a third silicone layer 40, a mounting cavity 41 is defined in the middle of the third silicone layer 40, and the second silicone layer 20 is mounted in the mounting cavity 41. A plurality of elastic members 50 are disposed in the mounting cavity 41, and the ends of the elastic members 50 are respectively connected to the second silicone layer 20 and the bottom of the mounting cavity 41. Specifically, the elastic members 50 are springs, which can further absorb the pressure exerted by the user's buttocks and further protect the heating element 30.

[0028] In one embodiment, Figure 2 and Figure 4 As shown, a positioning block 22 is provided on each side of the second silicone layer 20, and a positioning groove 42 is formed on the third silicone layer 40, which corresponds in position and size to the two positioning blocks 22. Each positioning block 22 is installed in a positioning groove 42. Specifically, the positioning groove 42 can provide installation positioning, so that the second silicone layer 20 can be accurately installed in the installation cavity 41.

[0029] In one embodiment, Figure 4 As shown, two elastic card blocks 12 are spaced apart on the first silicone layer 10, a through hole 220 is formed on each of the two positioning blocks 22, and two card holes 43 are spaced apart at the bottom of the mounting cavity 41. The elastic card blocks 12, the through holes 220, and the card holes 43 are aligned. After each elastic card block 12 passes through a through hole 220 and a card hole 43, it abuts against the side of the third silicone layer 40 away from the second silicone layer 20. Specifically, the elastic card blocks 12 are made of silicone. After the two elastic card blocks 12 are passed through the two through holes 220 and the two card holes 43, they pass out of the card holes 43, so that the elastic card blocks 12 abut against the side of the third silicone layer 40 away from the second silicone layer 20, thereby forming a stable connection between the first silicone layer 10, the second silicone layer 20, and the third silicone layer 40, forming a whole.

[0030] In one embodiment, the third silicone layer 40 is provided with an anti-slip layer on a surface away from the second silicone layer 20. The material of the protective layer is cotton cloth, and since the surface of the cotton cloth is rough, it can prevent the silicone seat cushion from sliding when the user uses it.

[0031] In one embodiment, Figure 1-Figure 3 As shown, a plurality of ventilation holes 13 are spaced apart on the side wall of each buffer cavity 11, and the ventilation holes 13 are set through the outer surface of the first silicone layer 10. Specifically, the ventilation holes 13 can discharge more heat generated by the heating element 30, thereby improving the heating effect when the user is using it.
