[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0024] As Figure 1 、 Figure 2, A row-connected low-noise and low-temperature-rise air valve, comprising a number of air valve units 1, the number of air valve units 1 being arranged side by side and pneumatically connected. The air valve unit 1 includes an upper valve body cover 11, a lower valve body 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. There is an upper and lower cover sealing ring between the upper valve body cover and the lower valve body cover, and they are locked and fixed on the fastening iron sheet by a pair of cover top screws. A silica gel sealing cap is provided at the center of the lower valve body cover. The valve body iron frame is riveted and fixed to the bottom of the fastening iron sheet. The winding support frame is arranged inside the valve body iron frame and its top is assembled and connected to the bottom of the fastening iron sheet. The copper wire coil is wound around the winding support frame. The valve body moving core is inserted into the inner cavity of the winding support frame and its top extends upward through the fastening iron sheet and is tightly connected to the silica gel sealing cap. The valve body fixed core is riveted and fixed at the center 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 this application lies in the creative improvement on the winding support frame. Among them, as Figure 3 shown, a number of outer ventilation channels 151 are provided on the outer side surface of the winding support frame 15, and a number of inner air guiding grooves 152 are provided on the inner side surface. The outer ventilation channels and the copper wire coil are on the same side. The ventilation channels can take away a large amount of heat generated by the energized power of the copper wire coil during ventilation, achieving an obvious cooling effect. This is a pioneering structural improvement. The inner air guiding grooves and the valve body moving core are on the same side, which can take away a large amount of heat generated during the movement of the valve body moving core, achieving the effect of rapid cooling of the valve body moving core heated in the magnetic field, reducing the temperature rise without weakening the multiple suction function. The gas in the inner air guiding grooves will also pass through the return spring synchronously, taking away the heat generated by the return spring during ventilation. A deflation buffer groove 153 is provided on the upper surface of the winding support frame 15. The upper surface fits with the fastening iron sheet, synchronously connecting the upper valve body cover and the lower valve body cover to form a relatively large buffer cavity. The buffer groove and the buffer cavity play a great pressure-reducing role at the moment when the gas is discharged under high pressure, reducing the deflation pressure of the gas during deflation and achieving the effect of reducing 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 effects achieved are also very obvious.

[0025] As Figure 4As shown, on both sides of the lower tabletop of the winding support frame 15, there are several air release grooves 154, and in the middle, there are matrix-type sound-absorbing columns 155. Similarly, the matrix-type sound-absorbing columns here are also a very important technological innovation and a breakthrough improvement. Previous products did not have such sound-absorbing improvements. The lower tabletop contacts the iron frame of the valve body. The sound-absorbing columns perform internal matrix gas cutting, and the air release grooves are matrix air release ports for gas to leak out to the outside. After the gas is first divided inside, the gas intensity decreases, and then it leaks out into the air through the air release grooves. The air release grooves serve as the last gas division, making the gas sound relatively loose and not generating a very strong gas noise, thereby reducing noise and improving the comfort of the human ear.

[0026] Figure 3 In it, on the corners of the upper tabletop of the winding support frame 15, there are connection positioning columns 156. On the fastening iron sheet 13, there are connection positioning holes corresponding to the positions of the connection positioning columns 156 and with completely matching shapes and dimensions. The fastening iron sheet and the winding support frame are assembled and fastened through the connection positioning columns and connection positioning holes. In this way, the winding support frame can be fixed very firmly, making it not easy to shake, and the moving core of the valve body can work better, with better use effects.

[0027] As Figure 5 shown, at the bottom of the upper cover 11 of the valve body, there is an assembly groove 111. At the top of the lower cover 12 of the valve body, there is an assembly boss 121 corresponding to the position of the assembly groove 111 and with completely matching shapes and dimensions. The upper cover of the valve body and the lower cover of the valve body are assembled and fastened through the assembly groove and the assembly boss. At the bottom of the lower cover 12 of the valve body, there is an assembly positioning column 122. On the fastening iron sheet 13, there is an assembly through hole 131 corresponding to the position of the assembly positioning column 122 and with completely matching shapes and dimensions. The lower cover of the valve body 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 more firm, there is no need for manual correction, the assembly efficiency is high, the components are not easy to fall off, the product consistency is good, and the use effect is better.

[0028] Preferably, the number of the air valve units 1 is more than one. Figure 6 、 Figure 7 、 Figure 8 They are in a row structure of 3, 5, and 6 respectively, not limited to this. The specific number can be determined according to actual needs. During production, the same mold can be used for production. For example, a 6-row mold can produce various row products with 1 to 6 valve body units. The mold cost is low and the production efficiency is high.

[0029] In order to further have a deeper understanding of the structure of the air valve, the air circuits for inflation and deflation will be described in detail below. As Figure 9As shown in the figure, when inflating, gas enters from the right port in the direction of the arrow and exits from the top air outlet to the container that requires gas. The specific working process is that after the copper wire coil conducts electricity, the moving core of the valve body is attracted by the magnetic field, compressing the return spring and causing it to suck in towards the fixed core of the valve body. The moving core of the valve body pulls the silica gel sealing cap, creating a gap between the originally tightly sealed upper cover of the valve body and the silica gel sealing cap. Gas then enters through the gap to achieve inflation. As Figure 10 shown in the figure, when deflating, gas enters the interior of the valve body from the top air 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 moving core of the valve body, under the action of the return spring bouncing back, pushes the silica gel sealing cap to fit and seal on the upper cover of the valve body, and the gas can then deflate in the direction of the arrow. Figure 10 It still doesn't look intuitive enough. As Figure 11 shown in the figure, the gas passes through the lower buffer chamber from the gap between the bottom of the silica gel sealing cap and the lower cover of the valve body, and then is discharged after secondary buffering. The gas flows as shown by the arrow.

[0030] The beneficial effects of the present utility model are as follows: By respectively arranging an air passage and an air guide groove on the inner and outer sides of the winding support frame, the temperature can be quickly exported and reduced. And buffer grooves, air release grooves, and matrix sound-absorbing columns are respectively arranged at its top and bottom. The buffer effect is good, the air release speed is fast, and the noise is small, greatly improving the noise reduction and temperature reduction effects. The product has good use effects, excellent user experience, low failure rate, long service life, low use cost, and effectively meets the use requirements.

[0031] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
