A heating air bag

Abstract

The utility model discloses a heating airbag, including an airbag shell, a heating tube fixed in the middle of the airbag shell cavity, and a temperature sensor installed at the side end of the heating tube. The utility model can heat the airbag shell in the cavity, and the heating temperature does not exceed 60 degrees Celsius. Unlike a traditional heating airbag, the surface of the airbag shell is not covered with heating wires, which may cause direct contact with the user and burn the user's skin. The utility model is worthy of promotion and application.

Description

Technical Field

[0001] The utility model relates to an extrusion massage device, in particular to an air bag, particularly a heating air bag. Background Art

[0002] Airbags can be used to squeeze and massage the body, such as leg massage and shoulder massage on a massage chair. However, when the existing airbags are used at very low temperatures, the airbag squeezing massage will feel very cold and uncomfortable, and cannot relieve fatigue. There are also heating airbags currently available. The heating method is to fix the heating wire on the outer surface of the airbag. This setting not only makes the heating wire easy to wear and damage, but also when the airbag is inflated, the volume will increase, and the heating wire will often be involved, which is easy to cause breakage and heating failure. The most important thing is that the heating wire is in direct contact with the user, causing the local temperature to be too high and easy to cause burns, which is not conducive to the needs of comfortable and safe use.

[0003] Chinese utility model patent CN 220370137 U discloses a laryngoscope pillow, including a laryngoscope pillow assembly, wherein the front and rear sides of the interior of the laryngoscope pillow assembly are respectively a telescopic auxiliary plate assembly A and a telescopic auxiliary plate assembly B, the inner centers of the two telescopic auxiliary plate assemblies A and B are connected with a telescopic column screw assembly, an inflatable heating assembly is provided at the inner top of the laryngoscope pillow assembly, a buckle groove is provided at the junction of the telescopic column screw assembly and the laryngoscope pillow assembly, and the inside of the buckle groove is covered with a locking buckle cover. This heating method adopts a surface heating method, and although the heating effect is faster, the temperature is more difficult to control, which is easy to cause burns. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings of the prior art and provide a heating airbag with in-airbag cavity heating, which meets the demand for comfortable use in low temperature weather environment.

[0005] The utility model solves the technical problem by adopting a technical solution: the heating airbag includes an airbag shell, a heating tube is fixed in the middle of the airbag shell cavity, and a temperature sensor is installed at the side end of the heating tube. The airbag shell and the heating tube are used to heat the airbag cavity after the airbag shell is inflated. The upper limit temperature of the heating tube is controlled at 60 degrees Celsius by the temperature sensor to avoid scalding to the user. The temperature sensor is an existing product on the market, and products of companies such as Beijing Saiyi Ling Technology Co., Ltd. and Wika Automation Instrument (Suzhou) Co., Ltd. can be selected.

[0006] Further improvement, temperature sensors are installed on both sides of the heating tube. Here, temperature sensors are installed on both sides of the heating tube to improve the sensitivity of sensing temperature in the airbag shell, avoid uneven temperature in the airbag cavity, and stop heating the heating tube after sensing the upper limit temperature.

[0007] Further improvement, the head end of the heating tube is set in a polygonal shape, and the polygon is a hexagon. The head end of the heating tube is a polygon here to increase the heating range, so that the airbag cavity is heated quickly and evenly.

[0008] Further improvement, the heating tube is provided with a support sleeve sleeved on the heating tube, and the bottom of the support sleeve is fixed to the airbag housing. Here, the function of the support sleeve is to support the heating tube to prevent the airbag housing from touching the heating tube when it is not inflated, thereby causing the heating tube to bend.

[0009] Further improvement, the corners of the support sleeve are fixed with reinforcing ribs. The function of the reinforcing ribs here is to increase the strength of the support sleeve.

[0010] The beneficial effects of the utility model are:

[0011] 1). It can heat the inside of the airbag cavity, and the upper limit temperature is controlled at 60 degrees Celsius, which will not cause burns;

[0012] 2). The heating tube in the airbag cavity heats quickly and evenly, avoiding discomfort caused by different temperatures in different areas;

[0013] 3). The supporting sleeve can support the heating tube to avoid the heating tube being accidentally bumped or twisted, which can prevent it from being used normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Referring to the accompanying drawings: this heating airbag includes an airbag shell 1, a heating tube 2 is fixed in the middle position of the cavity of the airbag shell 1, and a temperature sensor 3 is installed at the side end of the heating tube 2.

[0021] Temperature sensors 3 are installed on both sides of the heating tube 2 .

[0022] The head end of the heating tube 2 is arranged in a polygonal shape 2-1, and the polygonal shape 2-1 is a hexagon.

[0023] A supporting sleeve 4 which is sleeved on the heating tube 2 is provided on the heating tube 2 , and the bottom of the supporting sleeve 4 is fixed on the airbag housing 1 .

[0024] A reinforcing rib 4 - 1 is fixed at the corner of the supporting sleeve 4 .

[0025] The working principle of the utility model is as follows: when using the airbag for squeeze massage, it is only necessary to inflate and deflate the airbag through the airbag inflation port 5 repeatedly, and then turn on the power to heat the heating tube 2. After the air in the airbag shell is heated to an upper limit of 60 degrees Celsius, the temperature sensor 3 will sense the temperature and cut off the power to the heating tube 2, so that the temperature in the airbag is always controlled at 60 degrees Celsius, so that the user can comfortably use the airbag for massage in an extremely low temperature environment, and it is worthy of promotion and application.

[0026] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
