DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] This embodiment provides a pressure water tank used in a pressure system. The pressure in the pressure water tank can be stably monitored and adjusted, and the scale in the pressure water tank can be quickly cleaned, thereby ensuring a stable supply of hot water in the water tank.

[0025] Combination Figures 1 to 3 As shown, the pressure water tank of this embodiment includes a tank body 10, a regulating part 20, a cleaning part 30 and a control part 40. Hot water is stored in the tank body 10, and a pressure sensor is provided in the tank body 10. The pressure sensor monitors the pressure in the tank body 10 in real time. The regulating part 20 can regulate the pressure in the tank body 10 to keep the pressure in the tank body 10 in a stable state to ensure the hot water supply, while the cleaning part 30 can clean the scale in the water tank to ensure the water quality, and the control part 40 can exchange information and perform control to make each component work in an orderly manner.

[0026] In this embodiment, the regulating part 20 includes a first valve body 21 and a second valve body 22. The first valve body 21 and the second valve body 22 are both connected to the interior of the box body 10. The first valve body 21 is connected to an external air pump to inflate the box body 10, and the second valve body 22 is used to deflate the box body 10. When the pressure sensor detects that the air pressure in the box body 10 is lower than the set air pressure, the first valve body 21 is opened, and the external air pump is used to inflate the box body 10 until the air pressure in the box body 10 reaches the set air pressure. When the air pressure in the box body 10 is higher than the set air pressure, the second valve body 22 is opened to deflate the box body 10 until the air pressure in the box body 10 reaches the set air pressure.

[0027] Combination Figure 1 and Figure 3As shown, the cleaning part 30 includes a driver 31 and a cleaning roller 32 located at the driving end of the driver 31. The cleaning roller 32 is arranged at the bottom of the box body 10 to clean the scale at the bottom of the box body 10. The cleaning roller 32 is connected to the driver 31 through a coupling 60. The driver 31 of this embodiment is a driving motor. The driver 31 is installed on the surface of the box body 10 through an insulating block 50 to drive the cleaning roller 32. The cleaning roller 32 is driven by the driver 31 to clean the scale in the box body 10. The presence of the insulating block 50 of this embodiment can prevent the driver 31 from directly contacting the surface of the box body 10 and protect the driver 31. In addition, the cleaning part 30 of this embodiment is composed of two groups, which can better clean the scale in the box body 10.

[0028] Specifically, a plurality of roller brushes 321 are provided on the cleaning roller 32, and the roller brushes 321 scrub the scale on the inner wall of the box body 10. When the cleaning roller 32 rotates, it drives the roller brushes 321 to rotate. The roller brushes 321 are evenly distributed on the cleaning roller 32 to clean the scale on the inner wall of the box body 10.

[0029] Furthermore, a feed port 13 is provided on the box body 10, through which a cleaning liquid is introduced into the box body 10 to dissolve the scale in the box body 10. In this embodiment, the cleaning liquid provided by the feed port 13 is a citric acid solution. The citric acid forms a mixed liquid with the water in the box body 10. The mixed liquid can react with the scale. After standing for a period of time, the liquid can be discharged from the box body 10.

[0030] In this embodiment, a water inlet valve 11 is provided on the top of the box body 10, and a water outlet valve 12 is provided on the bottom. Water is injected into the box body 10 through the water inlet valve 11, and water is drained from the box body 10 through the water outlet valve 12. The presence of the water inlet valve 11 and the water outlet valve 12 is conducive to rapid water replenishment and drainage in the box body 10, and after cleaning the inside of the box body 10, the liquid in the box body 10 can be discharged by opening the water outlet valve 12, which is conducive to the rapid discharge of impurities.

[0031] In this embodiment, the control unit 40 is connected to the pressure sensor, the first valve body 21, the second valve body 22 and the driver 31 for information exchange and control. The control unit 40 of this embodiment is a control cabinet, which is installed on the surface of the box body 10 through an insulation pad. The pressure sensor feeds back the pressure signal inside the box body 10 to the control unit 40, and the control unit 40 controls the first valve body 21, the second valve body 22 and the driver 31 individually.

[0032] In actual use of the pressure water tank of this embodiment, when the pressure sensor located in the box body 10 monitors that the pressure in the box body 10 is not within the set air pressure range, the box body 10 is inflated through the first valve body 21 or the box body 10 is deflated through the second valve body 22. When the box body 10 has been used for a long time and there is a lot of scale inside it, the cleaning liquid is introduced into the box body 10 through the feed port 13. When the cleaning liquid is mixed with the water in the box body 10 to form a mixed liquid, the driver 31 of the cleaning part 30 drives the cleaning roller 32 to rotate, and the roller brush 321 on the cleaning roller 32 cleans the scale in the box body 10. After the cleaning is completed, the liquid can be discharged through the drain valve.

[0033] In summary, the pressure water tank of the present embodiment has a simple structure. With the cooperation of the pressure sensor and the regulating part 20, the pressure in the water tank can be monitored and adjusted, which is beneficial to maintaining a stable pressure in the water tank to ensure a stable supply of hot water. The presence of the cleaning part 30 can quickly clean the scale in the water tank, avoid the situation where the water quality is affected by scale accumulation in the water tank, and ensure the water quality in the water tank.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
