[0006] In the aforementioned waist support cushion with wide applicability, an electric heating wire is further arranged between the memory cotton backrest main part and the support plate, and the electric heating wire is connected with the battery group.

[0007] In the aforementioned waist support cushion with wide applicability, the inflation and deflation mechanism includes an inflation pipe and an exhaust pipe connected with the inflation port and the exhaust port at the bottom of the inflation and deflation bag layer, and control valves are arranged on the inflation pipe and the exhaust pipe. The inflation pipe is further connected with a gas pump, and the gas pump is connected with the battery group.

[0008] Compared with the prior art, the utility model discloses by backboard, with support plate's memory cotton back cushion main part and be located between the inflation and deflation bag layer composition, through the inflation and deflation bag layer's inflation condition is controlled, the support thickness of waist support pad is adjusted for can satisfy different use scene and different user, effectively expand the scope of application. Meanwhile, the present application is through setting up telescopic link and spring between support plate and backboard, can assist the smooth progress of blowing and deflation process. By setting up blow and deflation mechanism and battery pack, can realize electric inflation, convenient operation and adjustment. In summary, the utility model has the characteristics that can effectively expand the applicable range of waist support pad support thickness. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 1 It is the structural schematic diagram of the utility model.

[0010] The mark in the drawing is: 1-back plate, 2-memory cotton back cushion main body, 3-support plate, 4-inflation and deflation bag layer, 5-telescopic link, 6-tension spring, 7-bottom support plate, 8-blow and deflation mechanism, 9-battery pack, 81-inflation pipe, 82-outlet pipe, 83-control valve, 84-air pump. DETAILED DESCRIPTION

[0011] The utility model is further explained in connection with the drawings and examples below, but does not serve as the basis for the limitation of the utility model.

[0012] Example. A wide applicability waist support pad, constitutes as shown in Figure 1 The back surface of memory cotton back cushion main body 2 is equipped with support plate 3, and the upper and lower ends between support plate 3 and backboard 1 are equipped with telescopic link 5 and tension spring 6 that are sleeved on telescopic link 5, and the both ends of tension spring 6 are fixed on support plate 3 and backboard 1 respectively. The bottom of backboard 1 is equipped with bottom support plate 7, and bottom support plate 7 is equipped with blow and deflation mechanism 8 connected with inflation and deflation bag layer 4, and blow and deflation mechanism 8 is connected with battery pack 9.

[0013] Memory cotton back cushion main body 2 surface is equipped with antibacterial fabric.

[0014] The memory cotton back cushion main body 2 and support plate 3 are also equipped with electric heating wire, and the electric heating wire is connected with the battery pack.

[0015] The blow and deflation mechanism 8 includes inflation pipe 81 and outlet pipe 82 connected with the inflation port and outlet of the bottom of inflation and deflation bag layer 4, and control valve 83 is arranged on inflation pipe 81 and outlet pipe 82, and air pump 84 is also connected with inflation pipe 81, and air pump 84 is connected with battery pack 9.

[0016] The surface of support plate is equipped with wire groove for placing electric heating wire.

[0017] Preferably, through the setting of the antibacterial fabric, the antibacterial performance of the waist support cushion can be achieved.

[0018] Preferably, through the increase of the electric heating wire, the memory cotton cushion body can be heated, thereby heating the waist.

[0019] As preferred, the memory cotton cushion body is provided with grid-shaped air holes, which can improve the air permeability and also quickly conduct heat.

[0020] The working process of the utility model: when the air charging and discharging bag layer is not inflated, the tension spring provides a part of elastic support force, the memory cotton cushion body provides support force for the waist, and the two can well provide support force in cooperation; when it is needed to increase the support thickness, the battery pack supplies power, the air charging and discharging mechanism starts to inflate the air charging and discharging bag layer, and the corresponding support thickness is increased.

[0021] The operation process of the air charging and discharging mechanism: the air outlet pipe is communicated with the air bag main channel, and the air inlet pipe is communicated with the inflation opening; when it is needed to inflate, the control valve at the inflation pipe is opened, the control valve at the air outlet pipe is closed, the air pump starts to work, and the air charging and discharging bag layer is inflated to the set size, thereby meeting the use requirement; when inflating, the distance between the support plate and the back plate is expanded, and the tension spring is stretched.

[0022] When it is needed to deflate, the control valve at the inflation pipe is closed, the control valve at the air outlet pipe is opened, and deflation starts; at the same time, the tension spring is contracted and reset under the action of the spring force, the air charging and discharging bag layer is further compressed, and deflation is accelerated.

[0023] Further comprising a control main plate connected with the electric heating wire and the air charging and discharging mechanism, and the control main plate is connected with operation buttons (including a heating button, an inflation button and a deflation button).
