The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0041] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0042] The embodiment of the present application provides a liquid supply device 100, which is used to supply liquid to a liquid-requiring device. The liquid may be tap water, purified water, distilled water, etc. The liquid supply device may be a household appliance, a bathroom facility, or an industrial device, such as a smart toilet, a water heater, or a liquid phase analyzer, etc. In the following embodiments of the present application, a smart toilet is taken as an example for description.

[0043] like Figure 1 and Figure 2 As shown, the liquid supply device 100 includes a liquid storage component 1, a liquid pump component 2, an air intake component 3, an air exhaust component 4 and a liquid outlet pipe 5. The liquid storage component 1 includes a liquid storage tank 11, the liquid storage tank 11 has a liquid storage cavity 111, the liquid storage cavity 111 is used to store liquid, the liquid pump component 2, the air intake component 3, the air exhaust component 4 and the liquid outlet pipe 5 are all connected to the liquid storage cavity 111, the liquid pump component 2 is used to replenish liquid to the liquid storage cavity 111, the air intake component 3 is used to replenish gas to the liquid storage cavity 111, the air exhaust component 4 is used to discharge the gas in the liquid storage cavity 111, and the liquid outlet pipe 5 is used to discharge the liquid in the liquid storage cavity 111.

[0044] It should be noted that in the above embodiment, by adding gas to the liquid storage chamber 111 or discharging gas from the liquid storage chamber 111, the gas pressure above the liquid in the liquid storage chamber 111 can be adjusted, thereby adjusting the hydraulic pressure of the liquid in the liquid storage chamber 111, that is, adjusting the hydraulic pressure of the liquid discharged from the liquid outlet pipe 5. When the hydraulic pressure of the liquid discharged from the liquid outlet pipe 5 is high, the hydraulic pressure can be lowered, and when the hydraulic pressure of the liquid discharged from the liquid outlet pipe 5 is low, the hydraulic pressure can be increased, so that the hydraulic pressure of the liquid discharged from the liquid outlet pipe 5 is maintained within a range, improving the problem of poor stability of the liquid supply hydraulic pressure. When the liquid is water, the problem of unstable water supply pressure can be improved.

[0045] Moreover, the volume of gas has little effect on hydraulic pressure, that is, compared with directly controlling the increase or decrease of liquid in the liquid storage chamber 111 to control the hydraulic pressure of the liquid, to change the same hydraulic pressure, the volume of gas increase or decrease is larger, that is, indirectly controlling the hydraulic pressure through air pressure has higher accuracy and is more convenient to control the hydraulic pressure.

[0046] For the above liquid storage component 1, Figure 2As shown, the liquid storage assembly 1 also includes a pressure sensor 12 , a liquid level sensor 13 , a temperature sensor 14 , a safety valve 15 and a waste pipe 16 .

[0047] The liquid storage tank 11 may be cylindrical, and the two ends of the cylinder are hemispherical, and the shape of the liquid storage cavity 111 may be the same as the shape of the liquid storage tank 11, that is, the liquid storage tank 11 is a container with equal wall thickness. Optionally, the liquid storage tank 11 may be set to a larger volume to enhance the buffering capacity of the hydraulic pressure. Optionally, the liquid storage tank 11 is made of metal, such as steel or iron, to ensure that the liquid storage tank 11 has a strong pressure bearing capacity.

[0048] The pressure sensor 12, the liquid level sensor 13, the temperature sensor 14 and the safety valve 15 are all arranged on the liquid storage tank 11, for example, directly installed on the tank body of the liquid storage tank 11. Specifically, a plurality of mounting tubes 112 are arranged on the tank body of the liquid storage tank 11, and the mounting tubes 112 are connected with the liquid storage chamber 111. The liquid level sensor 13 and the temperature sensor 14 are respectively arranged in a mounting tube 112, and one end of the liquid level sensor 13 and the temperature sensor 14 extends into the liquid storage chamber 111 to detect the liquid level and temperature of the liquid in the liquid storage chamber 111; the pressure sensor 12 and the safety valve 15 are respectively arranged at the end of a mounting tube 112 away from the liquid storage chamber 111, the pressure sensor 12 is used to detect the air pressure in the liquid storage chamber 111, and the safety valve 15 is used to release the gas in the liquid storage chamber 111 when the air pressure is too high. It is understandable that the pressure sensor 12 , the liquid level sensor 13 , the temperature sensor 14 and the safety valve 15 all seal the mounting tube 112 in which they are located, so as to isolate the liquid storage chamber 111 from the external environment.

[0049] Furthermore, the mounting tube 112 where the liquid level sensor 13 and the temperature sensor 14 are located are both located at the top of the liquid storage tank 11, and the liquid level sensor 13 and the temperature sensor 14 both extend to the bottom of the liquid storage cavity 111, so that the requirements of the liquid level sensor 13 and the temperature sensor 14 on the liquid level in the liquid storage cavity 111 are reduced, that is, when the liquid level in the liquid storage cavity 111 changes within a large range, the liquid level sensor 13 and the temperature sensor 14 can still work normally.

[0050] Furthermore, if Figure 2 As shown, the mounting tube 112 where the pressure sensor 12 and the safety valve 15 are located are both located at the top of the liquid storage tank 11, and the pressure sensor 12 and the safety valve 15 are both located above the liquid storage chamber 111, so that when the liquid level in the liquid storage chamber 111 reaches the top of the liquid storage chamber 111, the pressure sensor 12 and the safety valve 15 will not contact the liquid, and the pressure sensor 12 and the safety valve 15 can still work normally.

[0051] The safety valve 15 is used to discharge the gas in the liquid storage chamber 111 when the air pressure in the liquid storage chamber 111 is greater than the safety air pressure, so as to improve the problem of excessive air pressure in the liquid storage chamber 111. Excessive air pressure may cause the pressure sensor 12, the liquid level sensor 13 and the temperature sensor 14 to be separated from the liquid storage tank 11, or cause the pipeline to be separated from the liquid storage tank 11 under hydraulic pressure or air pressure. The safety air pressure can be set to 90% of the maximum value of the working air pressure range of the liquid supply device 100 to ensure the safety of the liquid supply device 100.

[0052] The waste pipe 16 is connected to the liquid storage chamber 111, so that the waste water in the liquid storage chamber 111 can be discharged. It should be noted that the main impurities in the waste water are sediments, which will settle to the bottom of the liquid storage chamber 111. Therefore, the water inlet of the waste pipe 16 is located at the lowest point of the liquid storage chamber 111. Figure 1 and 2 As shown, the water inlet of the waste pipe 16 is lower than the water inlet of the liquid outlet pipe 5. When the liquid supply device 100 works normally, the liquid below the water inlet of the liquid outlet pipe 5 is not easy to flow, and the impurities in the liquid in the liquid storage chamber 111 will gradually accumulate. When the accumulation reaches a certain level, the waste water can be discharged by opening the waste pipe 16. It can be understood that the waste pipe 16 is provided with a valve (not shown) to open or close the waste pipe 16.

[0053] For the above-mentioned liquid pump assembly 2, as Figure 3 As shown, the liquid pump assembly 2 includes a liquid pump 21, a first pump pipe 22 and a second pump pipe 23. The liquid pump 21 is connected to the first pump pipe 22 and the second pump pipe 23 respectively. The first pump pipe 22 is connected to an external liquid source, and the second pump pipe 23 is connected to the liquid storage chamber 111 to replenish liquid into the liquid storage chamber 111. It can be understood that the water inlet of the second pump pipe 23 is higher than the water inlet of the liquid outlet pipe 5. Optionally, the liquid pump 21 is a centrifugal pump.

[0054] Furthermore, if Figure 3 As shown, the liquid pump assembly 2 also includes a third valve 24, which is arranged on the first pump pipe 22. The third valve 24 is used to control the opening and closing of the first pump pipe 22, thereby controlling the liquid to enter the liquid storage chamber 111. When the liquid pump 21 is closed, the first pump pipe 22 can be closed to improve the problem of liquid backflow. Optionally, the third valve 24 is an electric ball valve or a one-way valve. It is understandable that in some other embodiments, the third valve 24 can also be arranged on the second pump pipe 23, which is not limited here.

[0055] Furthermore, if Figure 3As shown, the liquid pump assembly 2 also includes a first flow meter 25, which is arranged on the second pump pipe 23. The first flow meter 25 is used to detect the flow rate of the liquid in the second pump pipe 23, so as to display the liquid inlet speed of the liquid storage chamber 111 in real time, so as to facilitate the staff to adjust the liquid inlet speed and to locate the fault when the liquid supply device 100 is abnormal. It can be understood that in some other embodiments, the first flow meter 25 can also be arranged on the first pump pipe 22, which is not limited here.

[0056] For the above-mentioned air intake component 3, if Figure 4 As shown, the air intake assembly 3 includes an air intake pipe 31 and a first valve 32. The air intake pipe 31 connects the external air source and the liquid storage chamber 111. The first valve 32 is arranged on the air intake pipe 31. The first valve 32 is used to control the opening and closing of the air intake pipe 31, thereby controlling the gas to enter the liquid storage chamber 111 to increase the air pressure above the liquid in the liquid storage chamber 111.

[0057] Optionally, the air inlet of the air inlet pipe 31 is located at the top of the liquid storage chamber 111, so as to avoid the introduction of gas into the liquid in the liquid storage chamber 111, thereby improving the problem of hydraulic instability caused by the liquid in the liquid storage chamber 111 being blown by the gas.

[0058] Optionally, the first valve 32 is a high-speed solenoid valve, which is a fast-response valve with a fast response speed and a short action time, and can achieve precise flow control.

[0059] Furthermore, if Figure 4 As shown, the air intake component 3 also includes a first flow regulating valve 33, which is arranged in the air intake pipe 31. The first flow regulating valve 33 is used to control the flow rate of gas when it is introduced, so that the gas can enter the liquid storage chamber 111 at a uniform speed, thereby improving the problem of large hydraulic pressure fluctuations in the liquid storage chamber 111 caused by unstable air intake speed.

[0060] For the above exhaust assembly 4, if Figure 4 As shown, the exhaust assembly 4 includes an exhaust pipe 41 and a second valve 42. The exhaust pipe 41 connects the external environment with the liquid storage chamber 111; the second valve 42 is arranged on the exhaust pipe 41, and the second valve 42 is used to control the opening and closing of the exhaust pipe 41, thereby controlling the gas to be discharged from the liquid storage chamber 111 to reduce the air pressure above the liquid in the liquid storage chamber 111.

[0061] The exhaust pipe 41 is connected to the top of the liquid storage tank 11 or close to the top of the liquid storage tank 11 to improve the problem of liquid flowing into the exhaust pipe 41. Optionally, the second valve 42 is a high-speed solenoid valve.

[0062] Furthermore, if Figure 4As shown, the exhaust component 4 also includes a second flow regulating valve 43, which is arranged in the exhaust pipe 41. The second flow regulating valve 43 is used to control the flow rate of gas during exhaust, so that the gas can be discharged from the liquid storage chamber 111 at a uniform speed, thereby improving the problem of large hydraulic pressure fluctuations in the liquid storage chamber 111 caused by unstable exhaust speed.

[0063] Furthermore, if Figure 4 As shown, the exhaust assembly 4 further includes a muffler 44, which is disposed on the exhaust pipe 41, specifically, on the exhaust port of the exhaust pipe 41, thereby reducing the noise generated by the exhaust assembly 4 when exhausting the gas, and reducing noise pollution.

[0064] Alternatively, if Figure 4 As shown, in some embodiments, the liquid supply device 100 further includes a connecting pipe 6, one end of which is in communication with the liquid storage chamber 111, and the other end of the connecting pipe 6 is respectively connected to the air inlet pipe 31 and the exhaust pipe 41, that is, the connecting pipe 6, the air inlet pipe 31 and the exhaust pipe 41 are connected in a "Y" shape. When the liquid storage chamber 111 needs to be inlet, the first valve 32 controls the air inlet pipe 31 to be in communication with the connecting pipe 6, the second valve 42 controls the exhaust pipe 41 to be closed with the connecting pipe 6, and the external air source enters the liquid storage chamber 111 through the air inlet pipe 31 and the connecting pipe 6. When the liquid storage chamber 111 needs to be exhausted, the first valve 32 controls the air inlet pipe 31 to be in communication with the connecting pipe 6, the second valve 42 controls the exhaust pipe 41 to be in communication with the connecting pipe 6, and the gas in the liquid storage chamber 111 is discharged through the connecting pipe 6 and the exhaust pipe 41.

[0065] For the above-mentioned liquid outlet pipe 5, if Figure 5 As shown, the liquid outlet pipe 5 is provided with a fourth valve 51, and the fourth valve 51 is used to control the opening and closing of the liquid outlet pipe 5, thereby controlling the liquid to be discharged from the liquid storage chamber 111. Optionally, the fourth valve 51 is an electric ball valve.

[0066] Furthermore, if Figure 5 As shown, the liquid outlet pipe 5 is also provided with a second flow meter 52, which is used to detect the flow rate of the liquid in the liquid outlet pipe 5, so as to display the liquid outlet speed of the liquid storage chamber 111 in real time, so as to facilitate the staff to adjust the liquid outlet speed and to locate the fault when the liquid supply device 100 is abnormal.

[0067] The embodiment of the present application also provides a smart toilet (not shown), which includes a liquid supply device 100. The liquid supply device 100 is used to supply water to the flushing structure of the smart toilet. The smart toilet has the structural features and beneficial effects of the liquid supply device 100, which will not be described in detail here.

[0068] The liquid supply device 100 and the smart toilet of the embodiment of the present application can adjust the hydraulic pressure of the liquid discharged from the liquid outlet pipe 5 by replenishing gas into the liquid storage chamber 111 or discharging gas from the liquid storage chamber 111, and can thereby lower the hydraulic pressure when the hydraulic pressure is too high, and increase the hydraulic pressure when the hydraulic pressure is too low, thereby improving the problem of poor stability of the liquid supply hydraulic pressure, and the hydraulic control is more accurate and more convenient to control.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments may also be combined, the steps may be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
