As shown in fig. 4, fig. 4 is a longitudinal sectional view of the main tank 4 and the pressure tank 5.

In an alternative embodiment of the heating pipe 6, the heating pipe 6 is specifically distributed at the bottom of the main water tank 4 and is arranged in line with the length direction of the pressure water tank 5, and the shape of the pressure water tank 5 is generally rectangular or round rectangular. Meanwhile, the adapter is additionally arranged in the embodiment, so that the heating pipe is connected with the pressure water tank conveniently. Specifically, the adapter is connected between the water inlet of heating pipe and pressure water tank's delivery port, and the both ends of adapter can be respectively the mouth of pipe of adaptation heating pipe and the mouth of pipe of pressure water tank. So set up, because heating pipe 6 is linear array with pressure tank 5, consequently, liquid flows into pressure tank 5 back from main water tank 4, can be along the flow direction quick through heating pipe 6 to accelerate the circulation velocity of flow of liquid, reduce noise and flow resistance simultaneously as far as possible.

As shown in fig. 5 and 6, fig. 5 is a schematic view illustrating an integrated mounting structure of the check valve module 11 and the relief valve module 12 on the isolation plate 10, and fig. 6 is a schematic view illustrating another view angle of fig. 5.

In an alternative embodiment with respect to the partition board 10, the partition board 10 mainly comprises an upper support board 101 and a lower support board 102. The upper support plate 101 and the lower support plate 102 are fastened together to form a boundary between the main tank 4 and the pressurized water tank 5. The surface of the upper support plate 101 is located in the main tank 4, and the bottom surface of the lower support plate 102 is located in the pressurized water tank 5. An installation cavity with a certain volume is formed between the upper support plate 101 and the lower support plate 102, and the number of the installation cavities is two, and the two installation cavities are respectively used for installing the one-way valve module 11 and the pressure relief valve module 12, so that the one-way valve module 11 and the pressure relief valve module 12 are integrally installed. Of course, the inner cavities of the two are not communicated.

In an alternative embodiment of the check valve module 11, in order to facilitate the steam pressure acting on the slit 113 to close it tightly, in this embodiment, flat curved surfaces 114 are formed on both side walls of the elastic portion 112. Generally, the two flat arcs 114 are symmetrical to each other, which is equivalent to a wedge-shaped portion cut off from the two side walls of the elastic portion 112 having a flat rectangular shape or a flat rounded rectangular shape, so that the shape of the elastic portion 112 gradually shrinks and becomes flat, and the slit 113 is formed at the end or bottom of the two flat arcs 114. So set up, when heating pipe 6 heats the liquid and produces steam pressure in pressure water tank 5, steam pressure will be acted on the flat cambered surface 114 in both sides of elasticity portion 112 simultaneously to form two-way extrusion effect to slit 113, and then make the flat cambered surface 114 in both sides produce the elastic compression, with slit 113 closed completely.

Meanwhile, in order to ensure that the liquid in the main tank 4 can smoothly pass through the check valve module 11, the water through hole 101 is specifically formed on the bottom surface of the mounting groove 102, so that the liquid in the main tank 4 can pass through the water through hole 101 and then enter the connecting portion 111, and then enter the pressure tank 5 through the elastic portion 112 and the slit 113.

In order to facilitate the assembling and disassembling operation between the connection portion 111 and the mounting groove 102, in the embodiment, the connection portion 111 also has elasticity, such as a rubber body, a silicon body, and the like, and the elastic portion 112 can also be made of an elastic material such as rubber, silicon gel, and the like. Meanwhile, the volume of the connecting portion 111 is slightly larger than that of the mounting groove 102, so that when the mounting is performed, the connecting portion 111 needs to generate certain elastic compression to be mounted in the mounting groove 102, and then the connecting portion 111 and the mounting groove 102 form an interference type clamping connection. With such an arrangement, the elasticity of the connecting portion 111 can also enhance the sealing performance, and when the detachment is required, the connecting portion 111 can be pulled out from the mounting groove 102 by force.

The float ring plate 1222 is connected to the sliding rod 1221, and is distributed along the circumferential direction of the sliding rod 1221, has a large surface area, and is mainly used for sensing steam pressure, so as to drive the sliding rod 1221 to perform vertical ascending motion. Meanwhile, the relief valve sealing gasket 125 is sleeved on the upper end area of the sliding rod 1221 and forms a tight fit with the float ring plate 1222 so as to abut against the exhaust port 124 of the relief valve when the sliding rod 1221 is lifted in place.
