[0019] The following is a further description of this product in conjunction with the accompanying drawings: Figure 1 The surface of the middle control box 1 is a display screen for displaying temperature and adjusting gears. The box is equipped with an air pump, a circuit board, and other electronic devices. The airbag 2 is an integrated distribution; Figure 1 The front of the knee pad is provided with a heating patch, which is mainly distributed along the herbal bag 3, from top to bottom, from the upper edge of the airbag 2 to the lower edge of the airbag 2, from the left to the leftmost end of the airbag 2, and from the right to the rightmost end of the airbag 2. The airbag ring 202 is where the herbal bag is placed, and the herbal bag 3 can be placed in the compartment; the patellar strap 4 is a built-in patellar strap, located on the back of the airbag.

[0020] Figure 2 It is a side view of the product, and the control box 1 is provided with an air inlet 5, an air inlet 6 and a charging port 7.

[0021] Figure 3In the figure, a knee pad belt 8 is provided on the back of the knee pad, and Velcro 1 9 and Velcro 2 10 are provided on the upper and lower parts of the knee pad belt 8 respectively; the wearing method shown in the figure is to loosen Velcro 1 9 and Velcro 2 10 first, put the knee pad belt 8 (with elastic part) into the knee first, and then place the patella belt 4 on the inside of the patella to fix the position, place it in the patellar groove of the knee, tighten Velcro 1 9 and Velcro 2 1, adjust the tightness by yourself, and complete the wearing.

[0022] The massage raised point 11 is located on the back of the airbag, separated from the heating patch; the raised point is in direct contact with the skin, and can massage the muscles when the airbag is inflated. At the same time, the raised point is cross-distributed with the airbag. When the airbag is inflated, the raised point can press around our knees to avoid the raised point pressing too hard on the leg muscles when the airbag is inflated, causing pain, and at the same time prevent the heating patch from producing unnecessary deformation.

[0023] Figure 4 This is a diagram showing the airbag 2. The gas is input by the air pump in the control box 1, flows through the airbag inlet 201 (marked by arrows) and enters the airbag ring 202, and then enters the left and right upper airbag channels 203 and the lower airbag channel 204 from the airbag ring 202, wherein the lower airbag channel 204 is in the shape of a "big" character. When the pressure sensor in the control box 1 reaches the set value, the air pump stops working, and the gas is released from the air leakage hole 4 in reverse.

[0024] The inflatable airbag 2 is combined with a control chip and a pressure sensor through an external air pump to play a pressing function. At the same time, the convex points 11 are evenly distributed on the inner side close to the skin, which can increase the comfort of massage and relieve the tension around muscles and joints.

[0025] Of course, the convex point 11 can also be matched with the acupuncture points on the knee pad to play the role of acupuncture point massage.

[0026] The heating patch of the knee pad adopts the commonly used polyimide PI heating film in the market, which has ideal strength and flexibility, good high temperature resistance, chemical stability and insulation performance, and is suitable for applications in heating environments. PI The shape of the heating film can be customized. PI The heating film is soft and plastic, and can be customized according to the customer's knee pad needs to produce a heating film that meets specific shape and size requirements.

[0027] This compression airbag is located in the interlayer of the knee pad and is made of TPU composite material. It has the characteristics of good toughness and wear resistance. The airbag structure is a full-body type, and each airbag chamber is connected by a trachea. The direction of the airbag is distributed according to the direction of the muscle, and a small protrusion is provided on the skin-friendly end to better achieve the massage effect. The upper end of the airbag is the main control room and the electric air pump is placed. The control room is equipped with a control chip 89C51 and an integrated circuit, and is equipped with an air inlet and an air outlet, which are all connected to the trachea. The user selects parameters such as massage program, massage intensity, and massage part through buttons. After the control chip receives the user's operation instructions, it calculates the airbag's inflation and deflation control signal, massage intensity control and other signals through a pre-set control algorithm. The calculated control signal is output to the airbag's inflation and deflation control valve to control the inflation and deflation and massage intensity of the airbag. This airbag realizes the massage function by cyclically inflating and deflation to change the air pressure in the bag. A gas pressure sensor and an air pump are placed in the interlayer of the sac. Similar to a cuff-type blood pressure meter, the control room is controlled by a wire connection. When the gas pressure in the sac reaches a certain value, the sensor transmits a signal to the electric air pump through a wire for inflation and deflation. The control room includes a manual button to adjust the inflation and deflation switch or an intensity button and a real-time pressure display, which allows users to better adjust the massage intensity. This massage function can massage muscles and relieve muscle soreness. For elderly patients, it can properly activate muscle levels and restore muscle activity. Relax the knees and promote blood circulation.
