[0034] Please refer to Figures 1 to 10 The embodiment of the utility model provides an integrated warm air water spray pressure reducing instant heating device, comprising a fixed bracket 1 installed in the toilet, a water inlet 2 fixedly arranged in the fixed bracket 1, a pressure reducing and constant pressure module 3 fixedly arranged in the fixed bracket 1 and one end of which is fixedly connected to the water inlet 2 by bolts, a flow meter 4 fixedly arranged in the fixed bracket 1 and one end of which is fixedly connected to the other end of the pressure reducing and constant pressure module 3, a heating and pressure relief module 5 fixedly arranged in the bracket and one end of which is fixedly connected to the other end of the flow meter 4, a distribution valve 6 fixedly arranged in the fixed bracket 1 and one end of which is fixedly connected to the other end of the heating and pressure relief module 5, a water sprayer 7 fixedly arranged in the fixed bracket 1 and connected to the distribution valve 6, and a warm air module 8 fixedly arranged in the fixed bracket 1.

[0035] like Figure 1 and Figure 2As shown, the fixed bracket 1 fixes the water inlet 2, the pressure reducing and constant pressure module 3, the flow meter 4, the heating and pressure relief module 5, the distribution valve 6, the sprinkler 7, and the warm air module 8 in itself, so that the device becomes an integrated module state, which is convenient for integrated installation in the toilet and also convenient for the overall module to leave the factory. When maintenance is needed, the entire device can be replaced as a whole and then brought back to the manufacturer for problem analysis, which reduces the maintenance time at the customer's place and improves maintenance efficiency. In addition, the water inlet 2, the pressure reducing and constant pressure module 3, the flow meter 4, the heating and pressure relief module 5, the distribution valve 6, and the sprinkler 7 are all connected in a fixed manner, without the need for conventional hoses on the market to connect to each other, thereby avoiding the problem of hose connections easily falling off, reducing the occupied space, saving the occupied volume, and ensuring the sealing and stability between each other.

[0036] Regarding the specific structural setting of the fixing bracket 1, as shown in FIG. Figure 2 and Figure 3 As shown, the fixed bracket 1 includes a lower bracket 12 fixedly installed in the toilet, and an upper bracket 11 fixedly connected to the lower bracket 12 by bolts, and the water inlet 2, pressure reducing and constant pressure module 3, flow meter 4, heating and pressure relief module 5, distribution valve 6, sprinkler 7, and warm air module 8 are respectively fixed on the lower bracket 12 and the upper end stroke is limited by the upper bracket 11, so as to achieve the effect of fixing the upper and lower ends at the same time, improve the stability of the device, make the device an integrated module, facilitate the overall installation in the toilet, and also facilitate the delivery of the overall module. When maintenance is needed, the entire device can be replaced as a whole and then brought back to the manufacturer for problem analysis, which reduces the maintenance time at the customer's place and improves the maintenance efficiency.

[0037] Regarding the specific structural setting of the water inlet 2, as shown in FIG. Figure 4As shown, the water inlet 2 includes a water inlet valve body 21 connected to an external water source, a one-way valve body 22 disposed in the water inlet valve body 21, at least one first water inlet sealing ring 23 disposed between the water inlet valve body 21 and the one-way valve body 22, a one-way valve plug 24 disposed in the one-way valve body 22, a water inlet spring 25 with one end pressed against the one-way valve plug 24, and a one-way valve cover 26 pressed against by the other end of the water inlet spring 25. By arranging the one-way valve plug 24 and the water inlet spring 25 pressed against the one-way valve plug 24 on the one-way valve body 22, the water inlet spring 25 is compressed when water source enters the one-way valve body 22 from the outside, and water flows normally. When water does not need to flow, the water inlet spring 25 presses against the one-way valve plug 24, and the water source is blocked by the one-way valve plug 24, so as to prevent the water source from flowing back, thereby ensuring the normal operation of the device. By setting a first water inlet sealing ring 23 between the water inlet valve body 21 and the one-way valve body 22, sealing between the water inlet valve body 21 and the one-way valve body 22 is achieved, avoiding the problem of the hose connection easily falling off, preventing water from seeping out, and improving the sealing performance of the device.

By providing a first pressure reducing sealing ring 33 between the water inlet valve body 21 and the pressure reducing valve body 31, sealing between the water inlet valve body 21 and the pressure reducing valve body 31 is achieved, thereby avoiding the problem of the hose connection easily falling off, preventing water from leaking out, and improving the sealing performance of the device.

By setting a fourth special-shaped sealing ring 59 between the pressure relief valve body 58 and the heating main shell 55, the sealing between the pressure relief valve body 58 and the heating main shell 55 is achieved. The special-shaped structure of the fourth special-shaped sealing ring 59 matches the pressure relief valve body 58, so as to better wrap the pressure relief valve body 58 for sealing, and further improve the sealing performance. By setting a fifth pressure relief sealing ring 512 between the pressure relief valve core 511 and the pressure relief spring 510, the sealing between the pressure relief valve core 511 and the pressure relief spring 510 is achieved, and the situation that the pressure relief spring 510 cannot be driven when the water pressure of the water source is too large is prevented.
