The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1The water supply device shown includes a water pipe 100, a faucet 200, a drain valve 300, and a sterilization component 400. The water pipe 100 forms a sterilization water path for the flow of sterilization water. The faucet 200 is connected to the water pipe 100. The drain valve 300 is connected to either the water pipe 100 or the faucet 200. The sterilization component 400 includes a heating device 41 connected to the water pipe 100. The sterilization water can be selectively discharged through the drain valve 300. With this design, after the sterilization water enters the water pipe 100, it flows into the sterilization component 400, is heated to a predetermined sterilization temperature, and then flows back into the water pipe 100 through a pump to sterilize the water pipe 100. The sterilized water is then discharged from the water pipe 100 through the drain valve 300. This method effectively sterilizes the water pipe 100 to ensure safe drinking water.

[0027] The technical details of each component will be introduced below.

[0028] In some implementations, such as Figure 1 As shown, the faucet 200 is equipped with at least one-way valve 01. The water outlet direction of the one-way valve 01 is consistent with the water outlet direction of the faucet 200 to prevent external water from being drawn back into the water pipe 100 through the faucet 200, thus avoiding contamination of the faucet 200 and the internal pipes of the water supply device.

[0029] In practical use, two check valves 01 can be connected in series along the water outlet direction of the faucet 200. Since the check valve 01 may leak, connecting the two check valves 01 in series ensures that if one check valve 01 leaks, the other check valve 01 can still prevent external water from being drawn back into the water pipe 100 through the faucet 200, thus enhancing the stability of the faucet 200's ability to prevent external water from being drawn back.

[0030] It is understandable that the aforementioned one-way valve 01 could also be a duckbill valve. The duckbill valve has a simpler structure than the one-way valve 01, which can save on production costs.

[0031] In some embodiments, the water supply device provided in this application further includes a detection mechanism connected to each one-way valve 01 to display the leakage status of each one-way valve 01. Based on the above structure, each one-way valve 01 is detachably connected to the faucet 200. The detection mechanism can test the performance of each one-way valve 01. When a one-way valve 01 leaks, the detection mechanism can display the leakage through sound or light, making it easy for the user to know and replace the one-way valve 01.

[0032] In some implementations, such as Figure 1As shown, the water supply device also includes a hot water NTC 700, which is installed at the faucet 200 to allow selective connection between the water pipe 100 and the faucet 200. In practical use, when the water supply device dispenses hot water, the first hot water flowing out is often at a lower temperature, failing to reach the user's desired temperature, thus affecting the user experience. Through the above design, the hot water NTC 700 can detect the temperature of the hot water about to be discharged through the faucet 200. If the hot water temperature is insufficient, the hot water NTC 700 will close the internal passage of the faucet 200, preventing the insufficiently heated water from being discharged. The insufficiently heated water will then be discharged from the water supply device through the drain valve 300. When the temperature of the hot water about to be discharged through the faucet 200 reaches the predetermined temperature, the hot water NTC 700 will open the internal passage of the faucet 200, allowing sufficiently heated water to be discharged for the user, thus ensuring that the hot water temperature is sufficient to meet the user's needs.

[0033] In some implementations, such as Figure 1 As shown, the sterilization component 400 is equipped with an inlet end 02, an outlet end 03, and a pump body. Both the inlet end 02 and the outlet end 03 are connected to different parts of the water pipe 100. The pump body is installed along the pipe from the inlet end 02 to the outlet end 03. Sterilizing water, under the action of the pump body, enters the sterilization component 400 from the water pipe 100 through the inlet end 02, is heated, and then flows back into the water pipe 100 from the outlet end 03. The heated sterilizing water can flow through the water pipe 100 back to the inlet end 02 and re-enter for reheating. Through this design, the sterilization component 400 can cyclically heat the sterilizing water. In actual use, if it is necessary to heat the sterilizing water to a higher temperature at once, a higher-power heating device 41 is required. Using the above-mentioned cyclic heating method, continuous cyclic heating of the sterilizing water can be achieved, allowing the sterilizing water to gradually reach the predetermined sterilization temperature.

[0034] Furthermore, such as Figure 1 As shown, the water pipe 100 includes an inlet end 11 and an outlet end 12. The inlet end 02 is located near the inlet end 11, and the outlet end 03 is located near the outlet end 12. The inlet end 11 and the outlet end 12 can be selectively connected. In this way, the sterilizing water can flow through more parts of the water pipe 100 during the circulation process, thereby making the sterilization of the water pipe 100 more comprehensive.

[0035] In some implementations, such as Figure 1As shown, the sterilization component 400 also includes a solenoid valve, which is located at the water inlet 02 to control the selective connection between the water inlet 02 and the water pipe 100. The solenoid valve allows drinking water in the water pipe 100 to flow into the pipe of the sterilization component 400 and accumulate when the water supply device is not initiating the sterilization process, which can have an adverse effect on drinking water hygiene over a long period of time.

[0036] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a back suction component 500, which is connected to a drain valve 300. The back suction component 500 can be selectively connected to the water pipe 100 and the sterilization component 400 through the drain valve 300 to draw out sterilized water, so as to avoid the sterilized water from causing adverse effects on drinking water hygiene.

[0037] Specifically, such as Figure 1 As shown, the aforementioned back-suction assembly 500 includes a back-suction pump 51, a back-suction pipe 52, and a waste discharge pipe 53. The back-suction pipe 52 and the waste discharge pipe 53 are respectively connected to the suction port and the discharge port of the back-suction pump 51. The end of the back-suction pipe 52 away from the back-suction pump 51 is connected to the drain valve 300. When discharging the sterilized water, the solenoid valve and the drain valve 300 are opened and the back-suction pump 51 is started. The back-suction pump 51 will suck out the sterilized water in the pipeline of the water pipe 100 and the sterilization assembly 400 through the back-suction pipe 52 and the drain valve 300, and then discharge it from the water supply device through the waste discharge pipe 53, so as to avoid the sterilized water from causing adverse effects on drinking water hygiene.

[0038] It is understandable that the aforementioned solenoid valve, waste discharge valve, and back suction pump 51 are all controlled by a preset control device.

[0039] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a heat exchange assembly 600, which includes a heat exchanger 61 and a heat storage tank 62. The heat exchanger 61 and the heat storage tank 62 are connected. The heat storage tank 62 contains a heat exchange medium. The heat exchange medium can circulate between the heat exchanger 61 and the heat storage tank 62 to provide heat to the heat exchanger 61. The heat exchanger 61 is used to transfer the heat of the heat exchange medium to the drinking water.

[0040] Specifically, the aforementioned heat storage tank 62 is equipped with an electric heating device, which is used to heat the heat exchange medium so that the heat exchange medium can absorb and store heat. A heat pump is provided between the heat exchanger 61 and the heat storage tank 62, which is used to drive the heat exchange medium to circulate between the heat exchanger 61 and the heat storage tank.

[0041] It should be noted that the heat exchange is only used for storing and releasing heat. During the flow of the heat exchange medium between the heat storage tank 62 and the heat exchanger 61, it continuously transfers the heat it carries to the drinking water, and finally flows back to the heat storage tank 62 for storage. In this way, heat can be stored in advance. When it is necessary to heat the drinking water, the heat in the heat exchange medium is transferred to the drinking water through the heat exchanger 61 to heat the water. Because heat can be stored in advance, the electric heating device installed in the heat storage tank 62 does not require a large power output, resulting in a smaller load on the circuit and safer operation.

[0042] Specifically, such as Figure 1 As shown, the heat exchanger 61 is provided with a water flow channel 612 and a medium channel 611 arranged at intervals. The water flow channel 612 is used for drinking water, and the medium channel 611 is used for heat exchange medium. The heat storage tank 62 is provided with an inlet 621 and an outlet 622, which are connected to the two ends of the medium channel 611 by pipes. The heat exchange medium flows out of the heat storage tank 62 through the outlet 622 and into the medium channel 611, and then flows back into the heat storage tank 62 from the inlet 621 to form a circulation. The medium channel 611 and the water flow channel 612 are spaced apart, and during the heat exchange process, the drinking water and the heat exchange medium only exchange heat in the heat exchanger 61 and do not come into contact with each other.

[0043] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
