[0022] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 A row of low-noise and low-temperature rise gas valves, comprising a plurality of gas valve units 1, the plurality of gas valve units 1 are arranged side by side and the gas paths are connected, the gas valve unit 1 comprises a valve body upper cover 11, a valve body lower cover 12, a fastening iron sheet 13, a valve body moving core 14, a winding support frame 15, a copper wire coil 16, a valve body fixed core 17 and a valve body iron frame 18, upper and lower cover sealing rings are arranged between the valve body upper cover and the valve body lower cover and are fastened to the fastening iron sheet by a pair of cover top screws, a silicone sealing cap is arranged at the center of the valve body lower cover, and the valve body iron frame is riveted and fixed to the bottom of the fastening iron sheet, The winding support frame is arranged in the valve body iron frame and the top is assembled and connected with the bottom of the fastening iron sheet. The copper wire coil is wound on the winding support frame. The valve body moving core is inserted into the inner space of the winding support frame and the top extends upward through the fastening iron sheet and is fastened with the silicone sealing cap. The valve body fixed core is riveted and fixed in the middle of the bottom of the valve body iron frame and is located directly below the valve body moving core. A return spring and a buffer gasket are provided between the valve body moving core and the valve body fixed core. This is the basic structure of the air valve and there is nothing special about it. The special feature of the present application is that creative improvements are made on the winding support frame, wherein, for example Figure 3As shown, the outer side of the winding support frame 15 is provided with a plurality of outer air passages 151, and the inner side is provided with a plurality of inner air guide grooves 152. The outer air passage is on the same side as the copper wire coil. The air passage can take away a large amount of heat generated by the power of the copper wire coil during ventilation, thereby achieving a significant cooling effect. This is a groundbreaking structural improvement. The inner air guide groove is on the same side as the valve body moving core, thereby taking away a large amount of heat generated by the valve body moving core during movement, thereby achieving the effect of rapid cooling of the valve body moving core when heated in the magnetic field, thereby reducing the temperature rise without weakening the multiple suction function. The gas in the inner air guide groove The heat generated by the return spring will also be taken away synchronously through the return spring during ventilation. The upper surface of the winding support frame 15 is provided with a deflation buffer groove 153, and the upper surface is fitted with the fastening iron sheet, and the valve body upper cover and the valve body lower cover are synchronously connected to form a larger buffer cavity. The buffer groove and the buffer cavity play a great role in reducing pressure at the moment when the high-pressure gas is released, so that the gas reduces the deflation pressure when deflated, thereby achieving the effect of reducing the deflation noise. Although these three points seem to be just simple improvements, they are breakthrough innovations in the industry. No product has been improved in this way, and the effect is also very obvious.

[0024] like Figure 4 As shown, a plurality of air relief grooves 154 are provided on both sides of the lower surface of the winding support frame 15, and a matrix silencer column 155 is provided in the middle. Similarly, the matrix silencer column here is also a very important technological innovation and a breakthrough improvement. Previous products have not had such silencer improvements. The lower surface is in contact with the valve body iron frame, the silencer column is the internal matrix gas cutting, and the air relief groove is the matrix air relief port for gas to be discharged to the outside. The gas is first divided internally and then the gas strength is reduced, and then it is discharged into the air through the air relief groove. The air relief groove serves as the last gas division, which makes the gas sound looser and does not produce strong gas noise, thereby reducing noise and improving people's ear comfort.

[0025] Figure 3 In the embodiment, the upper corners of the table top of the winding support frame 15 are provided with connecting positioning columns 156, and the fastening iron sheet 13 is provided with connecting positioning holes corresponding to the positions of the connecting positioning columns 156 and completely matching in shape and size. The fastening iron sheet and the winding support frame are assembled and fastened together through the connecting positioning columns and the connecting positioning holes. In this way, the winding support frame can be fixed very firmly, making it not easy to shake, and the valve body moving core can work better and have a better use effect.

[0026] like Figure 5As shown, the bottom of the valve body upper cover 11 is provided with an assembly groove 111, the top of the valve body lower cover 12 is provided with an assembly boss 121 and corresponds to the position of the assembly groove 111, and the shape and size are completely matched. The valve body upper cover and the valve body lower cover are assembled and fastened through the assembly groove and the assembly boss. The bottom of the valve body lower cover 12 is provided with an assembly positioning column 122, and the fastening iron sheet 13 is provided with an assembly through hole 131 and corresponds to the position of the assembly positioning column 122, and the shape and size are completely matched. The valve body lower cover and the fastening iron sheet are assembled and fastened through the assembly positioning column and the assembly through hole. In this way, the assembly is more convenient and simple, the connection is also tighter, no manual correction is required, the assembly efficiency is high, the parts are not easy to fall off, the product consistency is good, and the use effect is better.

[0027] Preferably, the number of the gas valve units 1 is more than one. Figure 6 , Figure 7 , Figure 8 The structures are 3, 5 and 6 in a row respectively, but not limited to them. The specific number can be determined according to actual needs. The mold can be shared during production. For example, a 6-row mold can produce a variety of row products of 1 to 6 valve body units. The mold cost is low and the production efficiency is high.

[0028] In order to have a deeper understanding of the structure of the air valve, the following is a detailed description of the air circuit for inflation and deflation. Fig. 9 As shown, when inflating, the gas enters from the right side port in the direction of the arrow, and is discharged from the top outlet to the container that requires gas. The specific working process is that after the copper wire coil is conductive, the valve body moving core is pulled by the magnetic field, compressing the reset spring to make it close to the valve body fixed core, and the valve body moving core pulls the silicone sealing cap to create a gap between the valve body upper cover and the silicone sealing cap that originally fit the seal, and the gas enters from the gap to achieve inflation; Fig.10 As shown in the figure, when the air is deflated, the gas enters the valve body from the top outlet in the direction of the arrow, while the air inlet on the right is closed. After the copper wire coil is powered off, the valve body moving core pushes the silicone sealing cap to fit and seal on the valve body cover under the rebound effect of the reset spring, and the gas can be deflated in the direction of the arrow. Fig.10 It doesn't seem intuitive enough. Fig.11 As shown, the gas passes through the gap between the bottom of the silicone sealing cap and the lower cover of the valve body through the lower buffer cavity and is discharged after secondary buffering. The gas flows as shown by the arrow.

[0029] The beneficial effects of the present invention are as follows: by respectively arranging air ducts and air guide grooves on the inside and outside of the winding support frame, the temperature is quickly discharged and reduced, and buffer grooves, air discharge grooves and matrix silencer columns are respectively arranged on the top and bottom thereof, the buffering effect is remarkable, the air discharge speed is fast and the noise is low, the noise reduction and cooling effect is greatly improved, the product has a remarkable use effect, the user experience is excellent, the failure rate is low, the use cycle is long, the use cost is low, and the use requirements are effectively met.

[0030] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
