[0002] With the improvement of people's material and cultural level, people pay more and more attention to the safety of drinking water. Water purifiers, or water purifiers as drinking water purification equipment, are increasingly entering people's lives.

[0003] The water purification system of the water purifier mainly includes a water supply pipeline that transports the incoming water to the tap, a filter element that filters the incoming water in the water supply pipeline, and a booster pump that provides the delivery power.

[0004] When the booster pump is working, it sucks the water flowing into the water supply pipeline, pressurizes it through the internal structure, and discharges the pressurized water into the discharge pipe of the water supply pipeline. It should be noted that in winter or in some cold areas, when the ambient temperature is 0℃ to 4℃, the density of water increases as the temperature decreases, causing the water to become heavier and the flow rate to slow down. At this time, the booster pump in the water purification system often cannot effectively suck the water in the water supply pipeline and discharge it at a higher pressure. The water inlet pipe of the booster pump is prone to water stagnation due to the slow water flow, resulting in water production difficulties or low water production efficiency in the water purification system. Summary of the invention

[0036] The present invention is specifically described below with reference to the embodiments:

[0037] The water purifier comprises a water purification system for receiving water, filtering the water and then discharging the water, and a shell structure for accommodating the water purification system.

[0038] Water purification system, such as attached Figure 1 To Attachment Figure 5 As shown, it includes a water supply pipeline, one end of which has a water supply port 1.11 for water to flow in, and the other end is connected to the water inlet of the water outlet faucet 2, so that water can flow into the water supply pipeline from the water supply port 1.11 and can transport the inflowing water to the water outlet faucet 2.

[0039] As attached Figure 1As shown in the figure, a plurality of functional components are arranged in the water supply pipeline. In the direction from the water supply port 1.11 of the water supply pipeline to the water outlet faucet 2, the plurality of functional components are in sequence: a first control valve 3 for controlling the opening / closing of the pipeline, a water purification filter element 4 for filtering the water in the pipeline, a booster pump 5 for pressurizing the water in the pipeline and delivering it to the water outlet faucet 2, and a second control valve 6 for controlling the opening / closing of the pipeline. Among them, the booster pump 5 includes a pump water inlet 5.1 for supplying water into the inner cavity of the booster pump 5 for pressurization, and a pump water outlet 5.2 for discharging the pressurized water from the inner cavity of the booster pump 5.

[0040] Adapt the settings of the above multiple functional components, such as the attached Figure 1 As shown in the figure, the water supply pipeline is divided, that is, in the direction from the water supply port 1.11 of the water supply pipeline to the water tap 2, the water supply pipeline is divided into: a water inlet pipe 1.1 with a water supply port 1.11, a first water pipe 1.2, a second water pipe 1.3, a third water pipe 1.4 and a water outlet pipe 1.5.

[0041] The water supply pipeline may also be provided with a pressure sensor 12 for measuring the water pressure of the water flowing inside the water supply pipeline.

[0042] When the first control valve 3 and the second control valve 6 both control the pipeline to be unblocked:

[0043] Water flows into the water inlet pipe 1.1 from the water supply port 1.11, and flows through the first control valve 3 and the first water pipe 1.2 in sequence, and then enters the water purification filter element 4 from the water inlet of the water purification filter element 4 for filtration. The filtered water flows out from the water outlet of the water purification filter element 4 to the second water pipe 1.3, and then flows through the second water pipe 1.3 and flows into the inside of the booster pump 5 from the pump water inlet 5.1 of the booster pump 5. Through the pressurization effect of the internal pressurization structure of the booster pump 5, it flows into the third water pipe 1.4 from the pump water outlet 5.2 of the booster pump 5, and then flows through the second control valve 6 and the water outlet pipe 1.5 in sequence, and enters the water inlet of the water outlet faucet 2. At this time, open the water outlet faucet 2 to discharge water.

[0044] To drain the water in the pipes when the system is in a long-term standby state.

[0045] As attached Figure 1 As shown in the figure, the water outlet pipe 1.5 is connected to the first water delivery pipe 1.2 through the first water return pipe 1.6, and the first water return pipe 1.6 is provided with a third control valve 7 for controlling its opening / closing. In addition, the third water delivery pipe 1.4 is connected to a drain pipe 1.7 for discharging water to the outside, and the drain pipe 1.7 is provided with a fourth control valve 8 for controlling its opening / closing.

[0046] accomplish:

[0047] When normal usage needs are met, the water purification system can be driven into water production mode, that is, by controlling the first control valve 3 and the second control valve 6 to be in an open state for water supply and circulation, and the third control valve 7 and the fourth control valve 8 to be in a closed state for blocking water circulation, and at the same time controlling the operation of the booster pump 5; that is, water production can be carried out as described above for water circulation.

[0048] Alternatively, when the water purification system needs to be in a long-term standby state, the water purification system can be driven into a drainage mode, that is, by controlling the first control valve 3 and the second control valve 6 to be in a closed state to block the flow of water, and the third control valve 7 and the fourth control valve 8 to be in an open state to supply water, and at the same time controlling the boost pump 5 to operate, drainage can be performed.

[0049] Specifically, when draining water, under the suction action of the booster pump 5, its pump water inlet 5.1 will form a negative pressure to suck the water flow in the pipeline, and then slowly draw the water in the outlet pipe 1.5, the first return pipe 1.6, the first water pipe 1.2, the water purification filter element 4, and the second water pipe 1.3 into the interior of the booster pump 5, and through the pressurization effect of the internal boosting structure of the booster pump 5, it is discharged from the pump water outlet 5.2 into the third water pipe 1.4, and then flows from the third water pipe 1.4 into the drain pipe 1.7, and is discharged outward from the drain pipe 1.7.

[0050] At this time, most of the water in the water purification system pipes will be discharged, achieving the drying of the water purification system pipes, which can meet the needs of long-term dry placement, reduce bacterial growth during placement, and thus increase the service life of the water purification system.

[0051] It is additionally noted that, in the above-mentioned drainage process, the booster pump 5 suctions the pipeline, and while the water in the pipeline (mainly the water in the water pipe 1.5, the first water return pipe 1.6, the first water delivery pipe 1.2, the water purification filter element 4, and the second water delivery pipe 1.3) is suctioned and discharged, a vacuum effect is also formed, driving the air pressure in the pipeline to decrease. In this way, when the water in the pipeline is drained to only a small part of liquid water that is difficult to discharge, vacuum drying or reduced pressure drying is achieved under the dual effects of pressure reduction and suction, so that this part of water is easy to vaporize and easier to discharge, thereby better drying the pipeline.

[0052] It should be noted that when the ambient temperature is low and the water flow rate in the water supply pipeline is slow, the booster pump 5 in the water purification system is often unable to effectively suck the water in the water supply pipeline and discharge it at a high pressure. The pump inlet pipe 5a of the booster pump 5 is prone to water stagnation due to the slow water flow, resulting in water production difficulties or low water production efficiency in the water purification system.

[0053] Based on this, a booster pump assembly having a heater 9 is provided in this embodiment.

[0054] Specifically, as attached Figure 2 To Attachment Figure 5 As shown, for the booster pump assembly, the booster pump 5 is fixedly connected with: a pump water inlet pipe 5a with one end open and the other end connected to the pump water inlet 5.1, which is used to receive water and supply water to the pump water inlet 5.1.

[0055] When attached Figure 1 As shown in , when the booster pump assembly is installed in a water purification system, the pump water inlet pipe 5a is detachably connected to the second water delivery pipe 1.3 so as to deliver water in the second water delivery pipe 1.3 to the pump water inlet 5.1.

[0056] The heater 9 is fixedly connected to the booster pump 5 or the pump water inlet pipe 5a, and is configured to fit the pump water inlet pipe 5a so as to transfer the generated heat to the inside of the pump water inlet pipe 5a. The booster pump 5, the pump water inlet pipe 5a and the heater 9 form a booster pump assembly that can be integrally installed / detached from the water purification system.

[0057] In this way, by setting the heater 9, when the ambient temperature is low and the booster pump 5 cannot pump water smoothly or there is a problem of water retention in the water inlet pipe, the heater 9 can be driven to heat, thereby increasing the temperature of the water inlet area of ​​the booster pump 5, so that the booster pump 5 can pump water smoothly and efficiently. Moreover, when draining water as described above, on the one hand, the water in the water supply pipeline can be heated to promote the flow of water and speed up the drainage efficiency; on the other hand, as described above, when the water in the pipeline is drained to only a small part of liquid water that is difficult to drain, heating and raising the temperature can further promote the vaporization of water and promote the flow of water vapor, making it easier to drain, so as to improve the drying effect of the pipeline.

[0058] The heater 9 is preferably detachably fixed to the booster pump 5 or the pump water inlet pipe 5 a using structures such as screws, so as to facilitate the removal and replacement of the heater 9 .

[0059] Furthermore, as attached Figure 4 As shown, the outer periphery of the pump water inlet pipe 5a is provided with a flange portion 5a.1, and the side of the flange portion 5a.1 facing the heater 9 is provided with: a receiving groove 5a.2 for accommodating the heater 9; at least a portion of the heater 9 is accommodated in the receiving groove 5a.2 and protected by the flange portion 5a.1, which can also form heat insulation protection, so that the heat generated by the heater 9 can act on the pump water inlet pipe 5a to a greater extent.

[0060] At this time, if the attached Figure 4 As shown in FIG. 1 , the heater 9 includes: a first heating portion 9.1 having a heating structure inside and surrounding the outer circumference of the pump water inlet pipe 5a; so as to perform surrounding heat transfer to the pump water inlet pipe 5a to improve the heating effect.

[0061] Furthermore, the heater 9 may further include: a second heating portion 9.2 protruding from the outer edge of the first heating portion 9.1 and having a heating structure inside; the second heating portion 9.2 is fitted to the flange portion 5a.1 to increase the contact area between the heater 9 and the pump water inlet pipe 5a, thereby improving the heating effect.

[0062] Based on the fitting arrangement of the flange portion 5a.1 and the heater 9, and taking into account the problem of poor heat transfer due to the high-speed movement of water in the pump water inlet pipe 5a, a cavity is also provided in this embodiment to slow down the water flow and temporarily hold the water for a short period of time, and the side wall of the cavity is matched and connected to the flange portion 5a.1, so as to transfer the heat generated by the heater 9 to the water in the cavity to improve the heating effect.

[0063] In one form, such as Figure 4 As shown, the interior of the flange 5a.1 is hollow and has a stagnation cavity 5a.3 connected to the internal flow channel of the pump water inlet pipe 5a. In this case, the stagnation cavity 5a.3 is the cavity body.

[0064] In another formation, such as Figure 2 To Attachment Figure 5 As shown, the booster pump 5 is provided with: an insertion slot 5.3 opening toward the pump water inlet pipe 5a and connected to the pump water inlet 5.1; the end of the pump water inlet pipe 5a has an interface section 5a.4 with an enlarged pipe diameter, and the flange portion 5a.1 is configured as a component of the pipe wall of the interface section 5a.4; and the slot of the insertion slot 5.3 and the pipe opening of the interface section 5a.4 are relatively grounded to form a water accumulation chamber 5c, and the pump water inlet pipe 5a is connected to the pump water inlet 5.1 through the water accumulation chamber 5c. At this time, the water accumulation chamber 5c is the above-mentioned cavity.
