[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-4 As shown:
[0026] A pressure-sensitive regulating water pump includes a booster pump 1, the inlet end 101 of the booster pump 1 is connected to a water storage tank, the outlet end 102 of the booster pump 1 is connected to an inlet pipe 2, the inlet pipe 2 is connected to an outlet pipe 4 through a regulating container 3, a flow sensor is installed at one end of the outlet pipe 4, and a one-way valve to prevent liquid backflow is installed at one end of the inlet pipe 2.
[0027] Air is always present at the top of the regulating container 3, and a pressure sensor 7 is installed at one end of the regulating container 3 to detect changes in the internal air pressure.
[0028] An air intake and exhaust pump 9 is installed at one end of the regulating container 3 to control the amount of gas inside the regulating container 3.
[0029] In this embodiment: the booster pump 1 will transport water from the water storage tank to the inside of the regulating part 302, and always leave air at the top of the inside of the regulating part 302. Moreover, this air has a certain pressure, which will increase the water pressure in the regulating container 3. The water pressure in the regulating container 3 can meet the user's water demand.
[0030] The gas pressure in the regulating container 3 needs to change with the user's water consumption. For example, if a user uses a small amount of water at night, the water pressure generated by the gas pressure in the regulating container 3 will meet the water consumption, causing the water level in the regulating container 3 to drop within a reasonable range. Due to the reduction in water volume, the gas pressure inside the regulating container 3 will also drop. The gas pressure sensor 7 can detect this change in gas pressure. At this time, it is only necessary to fill the regulating container 3 with gas through the air intake and exhaust pump 9 to keep the gas pressure inside the regulating container 3 constant. When the water volume in the regulating container 3 drops below the reasonable range, it is necessary to add water to the regulating container 3 through the booster pump 1. While adding water, the air intake and exhaust pump 9 needs to control the gas discharge to keep the gas pressure inside the regulating container 3 constant. This can avoid the frequent start-up of the booster pump 1 and meet the water demand in different scenarios. If the booster pump 1 is relied upon to meet the user's water pressure, frequent start-up will also lead to large fluctuations in water pressure. With the buffering of gas pressure, even if the water pressure changes, there will be no large fluctuations in water pressure.
[0031] Moreover, this method also reduces costs. Currently, there are alternatives to this device, such as constant pressure tanks or products with the same principle. However, constant pressure tanks rely on air bladders to provide pressure, which can pollute domestic water, are easily damaged, and have relatively high maintenance costs.
[0032] Furthermore;
[0033] In an optional embodiment, a temperature sensor 6 is installed at one end of the regulating container 3 to detect changes in the internal temperature of the regulating container 3. Changes in the external ambient temperature will cause changes in the gas pressure in the regulating container 3. By detecting the internal temperature of the regulating container 3, it is easy to determine whether the device is operating normally. For example, if no one is using water and the temperature does not change, but the gas pressure changes, it is necessary to check whether the regulating container 3 is leaking or has other malfunctions.
[0034] In an optional embodiment, a water level sensor 8 is installed at one end of the regulating container 3 to detect changes in the water level inside the regulating container 3. The water level sensor 8 can detect the water level in the regulating container 3.
[0035] In an optional embodiment, the regulating container 3 includes a water passage 301 and a regulating part 302. The water passage 301 is located below the regulating part 302, and the volume of the water passage 301 is smaller than the volume of the regulating part 302. The inlet pipe 2 and the outlet pipe 4 are both connected to the water passage 301. The regulating part 302 is mainly used to store water. The water in the inlet pipe 2 will enter the water passage 301 and then enter the outlet pipe 4. This will cause the water in the water passage 301 to fluctuate greatly. Since the volume of the water passage 301 is smaller than that of the regulating part 302, the water fluctuation mainly exists in the water passage 301 and has little impact on the water in the regulating part 302. This can reduce the degree of mixing between air and water and prevent the water from becoming acidic.
[0036] In an optional embodiment, a porous pipe 10 is connected between the inlet pipe 2 and the outlet pipe 4 located inside the water passage 301. When the impact generated by water fluctuation is transmitted to this area through the porous pipe 10, the water will disperse and flow through the numerous small holes on the porous pipe 10, thereby changing the movement form and energy distribution of the water flow. This dispersion effect can effectively buffer the energy impact brought by water fluctuation, further reduce the impact on the regulating unit 302, and ensure that the regulating unit 302 works normally in a relatively stable water flow environment.
[0037] In an optional embodiment, a partition 3021 is provided at the bottom of the regulating part 302, and a plurality of through holes 3022 are provided on the partition 3021. Through the partition 3021 and the through holes 3022, the fluctuation of water in the regulating part 302 can be further reduced.
[0038] In an optional embodiment, a water supply pipe 5 is connected between the water outlet pipe 4 and the regulating part 302. When the partition 3021, through hole 3022 and porous pipe 10 are provided, the water in the regulating part 302 is not easy to enter the water outlet pipe 4 stably. Therefore, the water supply pipe 5 is provided so that the water in the regulating part 302 can enter the water outlet pipe 4 directly, ensuring the stability of the water output from the water outlet pipe 4.
[0039] In an optional embodiment, the regulating container 3 further includes a detection unit 303, which is located above the regulating unit 302. The volume of the detection unit 303 is smaller than that of the regulating unit 302. The temperature sensor 6, the air pressure sensor 7, the water level sensor 8, and the air intake and exhaust pump 9 are all mounted on the detection unit 303. Because the detection unit 303 is relatively small in size, the chance and area of contact with water are reduced accordingly, which is more conducive to preventing water intrusion. It can prevent water from entering its interior and prevent the temperature sensor 6, the air pressure sensor 7, the water level sensor 8, and the air intake and exhaust pump 9 from getting wet. It should be noted that the temperature sensor 6, the air pressure sensor 7, the water level sensor 8, and the air intake and exhaust pump 9 all have waterproof and high temperature resistance properties.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
