Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a water outlet component and water supply equipment. Background Technology

[0002] To prevent residual water in the water outlet pipes from affecting the quality of drinking water, a backflow device is usually installed in the water outlet pipes to drain any remaining water after the water has been dispensed. However, during this backflow process, if the faucet is submerged in liquid, the faucet will draw the liquid back into the pipes. If the backflowed liquid is coffee, milk, or similar liquid, it can contaminate the water outlet pipes and may even damage the backflow pump in the backflow device. Utility Model Content

[0003] To address the problem in existing technologies that the back-suction of residual water may lead to the intake of other liquids, resulting in pipe contamination and damage to the back-suction pump, this invention provides a water outlet component and a water supply device.

[0004] This application provides a water outlet assembly, including a water outlet faucet, a backflow pump, and a detection component. The water outlet faucet is connected to a water outlet pipe and has a water outlet. The backflow pump is connected to the water outlet pipe. The detection component is connected to the water outlet faucet and is located near the water outlet. When the detection component detects that the water outlet is submerged in liquid, it can control the backflow pump to be in a closed state.

[0005] In some embodiments, the detection component includes a control module and a sensor, the control module being electrically connected to both the sensor and the backflow pump, and the sensor being positioned near the outlet.

[0006] In some embodiments, the sensor is disposed inside or outside or at the end of the water outlet, and the sensor can come into contact with the water flow when water is discharged from the water outlet.

[0007] In some embodiments, the sensor is disposed around the inside of the outlet.

[0008] In some embodiments, the sensor includes a first electrode and a second electrode, the first electrode and the second electrode being disposed at a relative interval;

[0009] Both the first electrode and the second electrode are electrically connected to the control module, which includes a conductivity detection module electrically connected to the first electrode and the second electrode.

[0010] In some embodiments, the thickness of the first electrode gradually decreases along the direction of the first electrode relative to the second electrode to form a wedge-shaped structure, and the second electrode is a mirror image of the first electrode.

[0011] In some embodiments, a baffle is provided on the side of the sensor that is closer to the external environment.

[0012] In some embodiments, the detection component includes a control module, a sensor, and a float. The sensor is connected to the control module and the float, respectively. The control module is electrically connected to the back-suction pump, and the float is positioned near the outlet.

[0013] When the outlet is submerged in liquid, the float can float to a predetermined position so that the sensor sends a signal to the control module.

[0014] In some embodiments, the water outlet assembly is further provided with a one-way valve, and along the extension direction of the water outlet pipe, the connection between the back suction pump and the water outlet pipe is located between the one-way valve and the water outlet tap.

[0015] This application provides a water supply device, including the aforementioned water outlet component.

[0016] Compared with existing technologies, the water outlet assembly provided by this utility model has the following advantages: the detection assembly is connected to the faucet and positioned near the water outlet; when the detection assembly detects liquid immersion, it can control the back suction pump to be in a closed state. Through this design, after the water flow from the faucet ends, if the water outlet is submerged in liquid, the detection assembly will control the back suction pump to be in a closed state, thereby preventing the back suction pump from drawing external liquid into it. This avoids contaminating the water outlet pipe and faucet with external liquid, and also prevents damage to the back suction pump if external liquid is drawn in. Attached Figure Description

[0029] like Figures 1 to 3The water outlet assembly shown includes a faucet 100, a backflow pump 200, and a detection component 300. The faucet 100 is connected to a water outlet pipe 500 and has a water outlet 11. Drinking water flows into the faucet 100 through the water outlet pipe 500 and then flows out from the water outlet 11. The backflow pump 200 is connected to the water outlet pipe 500 to extract water generated inside the water outlet pipe 500 and the faucet. The detection component 300 is connected to the faucet 100 and is located near the water outlet 11. When the detection component 300 detects that the faucet is submerged in liquid, it can control the backflow pump 200 to be in a closed state. With the above design, after the water outlet 100 finishes dispensing water, if the outlet 11 is submerged in liquid, the detection component 300 will control the back suction pump 200 to be in a closed state, thereby preventing the back suction pump 200 from sucking external liquid into the back suction pump 200. This not only prevents external liquid from contaminating the water outlet pipe 500 and the water outlet 100, but also prevents external liquids and other substances from being sucked into the back suction pump 200 and causing damage to the back suction pump 200.

[0030] The technical details of each component will be introduced below.

[0031] In some implementations, such as Figure 2 , Figure 3 As shown, the detection component 300 includes a control module and a sensor 31. The control module is electrically connected to both the sensor 31 and the backflow pump 200. The sensor 31 is positioned near the outlet 11. The sensor 31 can detect liquids. When the sensor 31 is submerged in liquid, it sends a signal to the control module. Upon receiving the signal from the sensor 31, the control module prevents the backflow pump 200 from operating, thereby preventing other liquids or substances from being drawn into the backflow pump 200 through the outlet 11.

[0032] In practical use, when a user uses the water outlet component provided in this application to brew a beverage, if the liquid level of the beverage exceeds the water outlet 11 after the brewing is finished, and if the detection component 300 does not prevent the back suction pump 200 from doing so, the back suction pump 200 will suck back the residual water in the water outlet pipe 500 and the water tap 100 after the water is dispensed. This will then suck the beverage into the water tap 100 and the water outlet pipe 500, and finally into the back suction pump 200, which will contaminate the water outlet pipe 500 and the water tap 100. If the beverage contains particulate matter, it may even damage the back suction pump 200. This application uses a sensor 31 installed at the outlet 11 to detect whether the outlet 11 is submerged in liquid. When liquid is submerged, a signal is sent to the control module to prevent the back suction pump 200 from working. When the outlet 11 is not submerged in liquid, the back suction pump 200 can back suction the residual water inside the outlet pipe 500 and the faucet 100 after the water is discharged, effectively avoiding the above-mentioned problems.

[0033] In some embodiments, the sensor 31 is disposed on the inner or outer side or end of the outlet 11, so that the sensor 31 can come into contact with the water flow when water flows from the outlet 11. Preferably, as... Figure 2 As shown, the sensor 31 is located inside the outlet 11. In this way, when water flows out of the outlet 11, the sensor 31 can come into contact with the water flow, preventing the backflow pump 200 from working while also rinsing the sensor 31. This ensures that the sensor 31 is cleaned every time water is discharged from the outlet 11, preventing the sensor 31 from being inaccurate due to the adhesion of other objects, which would affect the stability of the control of the backflow pump 200.

[0034] In addition to the aforementioned beneficial effects, placing the sensor 31 inside the water outlet 11 has two advantages: first, it reduces the probability of the sensor 31 colliding with or being impacted by external objects; second, it does not affect the external outline of the faucet 100. Therefore, it not only provides some protection for the sensor 31, but also maintains the original visual outline of the faucet 100.

[0035] Please see Figure 2 To more accurately determine whether the outlet 11 is submerged in liquid, multiple sensors 31 can be configured. These sensors 31 are arranged around the inner edge of the outlet 11 and are all connected to the control module. In practical use, if any one sensor 31 is submerged in liquid, the control module can receive the signal emitted by the sensor 31 and then prevent the backflow pump 200 from operating, thus improving the sensitivity and comprehensiveness of the detection device for the outlet 11.

[0036] Conversely, if the sensor 31 is only installed at one point on the inner edge of the outlet 11, when liquid is present on the side of the faucet 100 away from the sensor 31, the sensor 31 will not send a signal to the control module, and thus will not prevent the back suction of the back suction pump 200. Therefore, in actual use, there is still a high probability that the back suction pump 200 will suck external liquids and other substances into the back suction pump 200 through the faucet 100 and the outlet pipe 500.

[0037] In some implementations, such as Figure 3As shown, the sensor 31 includes a first electrode 311 and a second electrode 312, which are arranged at a distance from each other. Both the first electrode 311 and the second electrode 312 are electrically connected to a control module, which includes a conductivity detection module electrically connected to the first electrode 311 and the second electrode 312. It is understood that, due to the predetermined interval between the first electrode 311 and the second electrode 312, when the outlet 11 is not submerged in liquid, there is air between the first electrode 311 and the second electrode 312, and air has very low conductivity. If the outlet 11 is submerged in liquid, the interval between the first electrode 311 and the second electrode 312 is filled with liquid, and the conductivity of liquid is higher than that of air. As is well known, under normal circumstances, the conductivity of liquid is much higher than that of air. In other words, in the living environment, liquid conducts current more easily than air. The conductivity detection module can detect the conductivity between the first electrode 311 and the second electrode 312. If the outlet 11 is submerged in liquid, the spacer material between the first electrode 311 and the second electrode 312 will change from air to liquid, which greatly increases the conductivity between the first electrode 311 and the second electrode 312. By observing the change in conductivity, it is possible to effectively determine whether the outlet 11 is submerged in liquid, thereby effectively preventing the back suction pump 200 from sucking external liquids and other substances into the back suction pump 200 through the outlet pipe 500 and the faucet 100.

[0038] In some implementations, such as Figure 4 As shown, along the direction of the first electrode 311 relative to the second electrode 312, the thickness of the first electrode 311 gradually decreases to form a wedge-shaped structure, and the second electrode 312 is a mirror image of the first electrode 311. It should be noted that due to the surface tension of the liquid, the gap between the first electrode 311 and the second electrode 312 is small. Under the action of the liquid surface tension, liquid may remain in the gap between the first electrode 311 and the second electrode 312, leading to a decrease in the conductivity between them. Through the above structural design, liquid can be prevented from remaining in the gap between the first electrode 311 and the second electrode 312, thereby ensuring the consistency between the detection status of the detection component 300 and the actual situation.

[0039] In some implementations, such as Figure 5As shown, a baffle 313 is provided on the side of the sensor 31 closest to the external environment. Since the outlet 11 is open, other external objects may collide with the sensor 31 through the outlet 11, thereby affecting the safety of the sensor 31. The sensor 31 is generally a relatively delicate structure and is easily damaged by collisions. Through the above design, when an external object collides with the sensor 31, the baffle 313 can block the external object, thus providing good protection for the sensor 31.

[0040] Furthermore, the aforementioned baffle 313 is a grid structure with multiple gaps, through which liquid can contact the sensor 31. This allows the baffle 313 to protect the sensor 31 without obstructing the contact between the liquid and the sensor 31.

[0041] In other embodiments, the detection component 300 includes a control module, a sensor 31, and a float. The sensor 31 is connected to both the control module and the float. The control module is electrically connected to the backflow pump 200. The float is positioned near the outlet 11. When the outlet 11 is submerged in liquid, the float can float to a predetermined position to allow the sensor 31 to send a signal to the control module. With this design, the float can effectively detect liquid, and thus can accurately detect whether the outlet 11 is submerged in liquid.

[0042] In some embodiments, the water outlet assembly provided in this application is further provided with a one-way valve 400. Along the extension direction of the water outlet pipe 500, the connection between the back suction pump 200 and the water outlet pipe 500 is located between the one-way valve 400 and the water tap 100. The one-way valve 400 has a predetermined water outlet resistance (the water flow needs to have a predetermined pressure to pass through). The connection direction of the one-way valve 400 is the water outlet direction of the water outlet pipe 500. When the back suction pump 200 back suctions residual water, the one-way valve 400 can preferentially allow the water remaining in the water outlet pipe 500 and the water tap 100 to be sucked away by the back suction pump 200. Since the one-way valve 400 has a predetermined water outlet resistance, the back suction pump 200 will not draw out drinking water from the inlet side of the one-way valve 400 when it is working.

[0043] The water supply device provided in this application includes the above-mentioned water outlet component, which can prevent other external liquids or substances from being sucked into the back suction pump 200 through the water outlet faucet 100 and the water outlet pipe 500 when the back suction pump 200 is working. This avoids pipe contamination and protects the back suction pump 200.

[0044] The aforementioned water supply equipment also includes a heat exchanger 01 and a heat storage tank 02. The heat storage tank 02 contains a heat exchange medium and is equipped with an inlet and an outlet for the circulation of the heat exchange medium. The heat exchanger 01 has a heat exchange medium channel 011 and a drinking water channel 012, which are spaced apart. The two ends of the heat exchange medium channel 011 are connected to the inlet and outlet of the heat storage tank 02, respectively. A water pump 03 is also installed between the heat exchanger 01 and the heat storage tank 02 to drive the circulation of the heat exchange medium. When the water pump 03 is working, it circulates the heat exchange medium with a higher temperature inside the heat storage tank 02 to the heat exchange medium channel 011 of the heat exchanger 01. At this time, the heat of the heat exchange medium enters the drinking water channel 012 through the heat exchange medium channel 011 to heat the drinking water. The heated drinking water flows out from the drinking water channel 012, then flows into the outlet pipe 500 through the pipe and can be discharged from the faucet 100.

[0045] The aforementioned method of heating drinking water via a heat storage tank 02 and a heat exchanger 01 allows the water supply equipment to store heat in advance through the heat storage tank 02. When heating is needed, the heat is transferred to the drinking water through the heat exchanger 01. This eliminates the need for pre-heating and storing the drinking water, enabling instant hot water supply and ensuring the quality of the drinking water. Existing instant hot water supply equipment typically uses high-power electric heating devices to quickly heat the flowing drinking water. However, the water supply equipment provided in this application uses a heat exchanger 01 and a heat storage tank 02 to exchange heat with the drinking water, allowing for pre-heat storage and instant hot water supply without the need for a high-power heating device.
