[0006] Furthermore, the demonstration system also includes a pressure reducing valve arranged at the water outlet end of the water pump, and the pressure reducing valve is used to reduce the water flow pressure sucked by the water pump to the water purifier.

[0007] Furthermore, the demonstration system also includes a high-pressure switch disposed between the water outlet of the water pump and the pressure reducing valve, wherein the high-pressure switch is electrically connected to the water pump to control the start or shut down of the water pump.

[0008] Furthermore, the demonstration system also includes a rocker switch electrically connected to the water pump, and the rocker switch is used to perform power-off protection on the water pump.

[0009] Furthermore, the faucet includes a water purification faucet for outputting purified water treated by the water purifier, and a pure water faucet for outputting pure water treated by the water purifier. The water purification faucet and the pure water faucet are both connected to the water outlet of the water purifier, and the water receiving tank receives the water output by the water purification faucet and the pure water faucet.

[0010] Furthermore, the water receiving tank includes a clean water tank for receiving water output from the clean water faucet, a pure water tank for receiving water output from the pure water faucet, and a partition arranged between the clean water tank and the pure water tank, wherein the partition is used to separate the clean water tank from the pure water tank.

[0011] Furthermore, the water circulation port is arranged on the clean water tank, and the water pump draws water in the clean water tank to the water purifier.

[0015] The utility model provides a water supply demonstration system for a water purifier with the following gain effects:

[0016] (1) This demonstration system pumps water from the water tank into the water purifier, and the faucet outputs the treated water from the water purifier. The water tank receives the water output from the faucet outlet, thereby facilitating the use of the water purifier in an environment without water supply. This solves the problem that offline stores are limited by the lack of water sources and cannot demonstrate the normal working conditions of the water purifier during experience promotion, thereby increasing users' purchasing desire;

[0017] (2) In this demonstration system, the water treated by the water purifier is delivered to the faucet, which then outputs the water to the water receiving tank. The water in the receiving tank is then pumped into the water purifier by a water pump for treatment. In this process, water is recycled and resources are saved.

[0018] (3) A pressure reducing valve is provided between the water outlet of the water pump of this demonstration system and the water purifier. When the water pump supplies water to the water purifier, the water flow is first reduced in pressure by the pressure reducing valve before entering the water purifier. Thus, the water flow pressure entering the water purifier is reduced by the pressure reducing valve, thereby protecting the water purifier and extending the service life of the water purifier.

[0019] (4) This demonstration system is provided with a high-pressure switch between the water outlet of the water pump and the pressure reducing valve. The high-pressure switch controls the start and shut down of the water pump, so that the switch from the working state to the non-working state of this demonstration system can be completed without manual operation, thereby making the use of this demonstration system simpler, more convenient and easier to implement;

[0020] (5) The water receiving tank of the demonstration system includes a clean water tank, a pure water tank and a partition. The clean water tank receives the water output from the clean water faucet, and the pure water tank receives the water output from the pure water faucet. The partition separates the clean water tank from the pure water tank, so that the water purifier demonstration system can better display the working conditions of the water purifier and enhance the user's purchasing desire;

[0021] (6) The height of the partition of this demonstration system is less than the depth of the clean water tank and the pure water tank. When the water output from the pure water faucet reaches the upper limit of the water level in the pure water tank, it will flow from the top of the partition into the clean water tank and then be pumped into the water purifier by the water pump. This can prevent the water in the pure water tank from overflowing and affecting the on-site environment, and also recycle the water in the pure water tank to save resources, thereby making this water purifier demonstration system more practical.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 to Figure 3 A water supply demonstration system of a water purifier according to an embodiment of the utility model comprises a water pump 1, a faucet, and a water receiving tank 2. The water receiving tank 2 is provided with a water circulation port 21. The water inlet end of the water pump 1 is connected with the water circulation port 21, and the water outlet end is connected with the water inlet of the water purifier 8, so as to pump the water in the water receiving tank 2 to the water purifier 8. The faucet is connected with the water outlet of the water purifier 8, so as to output the water treated by the water purifier 8. The water receiving tank 2 is arranged under the faucet to receive the water outputted from the faucet.

[0029] In the present application, the water purifier demonstration system is connected to the water circulation port 21 through the water inlet of the water pump 1, and the water outlet is connected to the water inlet of the water purifier 8, so that the water pump 1 pumps the water in the water tank 2 into the water purifier 8. The water outlet of the water purifier 8 is connected to the faucet, and the treated water in the water purifier 8 can be output by turning on the faucet. The water tank 2 is set below the water outlet of the faucet, so that the water tank 2 receives the water output from the water outlet of the faucet, thereby facilitating the use of the water purifier 8 in an environment without water supply, thereby solving the problem that offline stores are limited by the lack of water sources and cannot show the normal working conditions of the water purifier 8 during experience promotion, thereby enhancing users' desire to buy.

[0030] Specifically, at the beginning of the demonstration, the water circulation port 21 of the water receiving tank 2 is first closed, and an appropriate amount of water to be purified is added to the water receiving tank 2; then the water circulation port 21 of the water receiving tank 2 is opened, and the water pump 1 is started at the same time, so that the water pump 1 pumps the water in the water receiving tank 2 to the water purifier 8, and the water purifier 8 purifies the water; the water treated by the water purifier 8 is transported to the faucet, and the faucet outputs the water to the water receiving tank 2; the water in the water receiving tank 2 is then sucked by the water pump 1, so that in this process, water recycling is realized and resources are saved.

[0031] In this embodiment, the demonstration system further includes a pressure reducing valve 3 provided at the water outlet of the water pump 1, and the pressure reducing valve 3 is used to reduce the water flow pressure pumped by the water pump 1 to the water purifier 8. In this application, the demonstration system further includes a pressure reducing valve 3, and since the water outlet of the water pump 1 is connected to the water purifier 8, the pressure reducing valve 3 is provided between the water outlet of the water pump 1 and the water purifier 8.

[0032] Since during the water supply demonstration, when the water supply pressure of the water pump 1 is too high, long-term use is not conducive to the service life of the water purifier 8, in this application, a pressure reducing valve 3 is provided between the water outlet of the water pump 1 and the water purifier 8. When the water pump 1 supplies water to the water purifier 8, the water flow is first reduced in pressure by the pressure reducing valve 3 and then enters the water purifier 8, thereby reducing the pressure of the water flow entering the water purifier 8 through the pressure reducing valve 3, protecting the water purifier 8 and extending the service life of the water purifier 8.

[0033] Example 1, see Figure 1 :

[0034] In this embodiment, the demonstration system further includes a high-pressure switch 4 disposed between the water outlet of the water pump 1 and the pressure reducing valve 3, and the high-pressure switch 4 is electrically connected to the water pump 1 to control the start or shut down of the water pump 1. In this application, the demonstration system further includes a high-pressure switch 4, and the high-pressure switch 4 is disposed between the water outlet of the water pump 1 and the pressure reducing valve 3. When the water pump 1 supplies water to the water purifier 8, the water flow output from the water outlet of the water pump 1 first passes through the high-pressure switch 4, then passes through the pressure reducing valve 3, and finally is delivered to the water purifier 8.

[0035] During the water supply demonstration, the faucet is opened, and the water flow delivered to the water purifier 8 is output through the faucet. The water supply of the water pump 1 and the water delivery of the faucet reach a balance state, so that a low water flow pressure is maintained in the water channel. At this time, the high-pressure switch 4 is used for control to put the water pump 1 in a working state; when the water supply demonstration is not being carried out, the faucet is closed and no water flow is output, while the water pump 1 continues to pump water, resulting in an increase in the water flow pressure at the outlet of the water pump 1. After reaching the rated water flow pressure of the high-pressure switch 4, the water pump 1 is controlled to be closed through the high-pressure switch 4. Therefore, after the water supply demonstration is over, only the faucet needs to be closed, and no other manual operation is required to complete the conversion of the demonstration system from the working state to the non-working state, thereby making the use of the demonstration system simpler, more convenient and easier to implement.

[0036] Since in this application, water is supplied to the water purifier 8 by the water pump 1, the flow rate of the water pump 1 can be configured according to the required water volume L of the water purifier 8. In this application, since the high-pressure switch 4 controls the start or stop of the water pump 1 by the water flow pressure in the water path, the selection of the high-pressure switch 4 is related to the water supply of the water pump 1 and the water output of the water purifier 8.

[0037] The water outlet flow rate of the water purifier 8 is V1, and the water outlet flow rate of the water pump 1 when working is V2. The pressure formed by the height difference of the water supplied by the water pump 1 can be ignored. According to the Bernoulli equation, the water flow pressure on the water supply pipeline is P = 0.5ρ (V2 2-V1 2), so the rated disconnection pressure of the high-pressure switch 4 should not be lower than the pressure P on the water supply pipeline. Preferably, the water outlet pressure of the water pump 1 is 0.2MPa, the water outlet flow rate of the water pump 1 reaches L, and the rated disconnection pressure of the high-pressure switch 4 can be selected to be ≥ 0.5MPa.

[0038] Example 2, see Figure 2 :

[0039] In this embodiment, the demonstration system further includes a rocker switch 5 electrically connected to the water pump 1, and the rocker switch 5 is used to power off the water pump 1. In the present application, the demonstration system further includes a rocker switch 5, and the rocker switch 5 is electrically connected to the water pump 1, so that the water pump 1 can be started or shut down by the rocker switch 5. When performing a water supply demonstration, the button of the rocker switch 5 is first turned on, so that the water pump 1 is powered on by the rocker switch 5, and the water pumping function is started; after the demonstration, the button of the rocker switch 5 is turned off, so that the water pump 1 is powered off by the rocker switch 5, and the water pumping function is shut down.

[0040] It is foreseeable that the boat switch 5 can not only control the start and stop of the water pump 1 in a normal state, but also cut off the power supply to protect the water pump 1 in an emergency state. For example, during the water supply demonstration, when the water outlet of the water purifier 8 is blocked or the faucet is blocked, resulting in the inability to output water, the water pump 1 continues to pump water, resulting in an increase in the water flow pressure at the outlet of the water pump 1, which will not only increase the workload of the pressure reducing valve 3, but may also cause damage to the water pump 1 and the water purifier 8. At this time, the button of the boat switch 5 can be manually controlled to be closed, and the water pump 1 can be powered off to stop pumping water, thereby protecting the water pump 1, the pressure reducing valve 3 and the water purifier 8.

[0041] Since in the present application, both the high-voltage switch 4 and the rocker switch 5 can provide overcurrent protection for the water pump 1, in actual implementation, the high-voltage switch 4 in Example 1 and the rocker switch 5 in Example 2 can be used separately, that is, one of the high-voltage switch 4 and the rocker switch 5 can be selected for use according to actual production needs.

[0042] The high-pressure switch 4 and the boat-type switch 5 can also be used in combination, that is, the high-pressure switch 4 and the boat-type switch 5 are simultaneously provided at the water outlet of the water pump 1. When the water flow pressure at the water outlet of the water pump 1 reaches the rated disconnection pressure of the high-pressure switch 4, the high-pressure switch 4 automatically turns off the water pump 1. However, when the high-pressure switch 4 fails, the button of the boat-type switch 5 can be manually controlled to turn off, so that the water pump 1 is powered off, thereby providing double protection for the water pump 1 and further improving the safety performance of the water purifier demonstration system. It can be foreseen that: in the specific implementation, no matter which implementation method is adopted, the high-pressure switch 4 and the boat-type switch 5 need to be connected to the mains 10 through the adapter 9, so as to realize the power-on of the high-pressure switch 4 and the boat-type switch 5.

[0043] In this embodiment, the faucet includes a clean water faucet 6 for outputting clean water treated by the water purifier 8, and a pure water faucet 7 for outputting pure water treated by the water purifier 8. The clean water faucet 6 and the pure water faucet 7 are both connected to the water outlet of the water purifier 8, and the water receiving tank 2 receives the water outputted by the clean water faucet 6 and the pure water faucet 7. An existing water purifier 8 has two functions of water purification and pure water. The water purification function of the water purifier 8 refers to removing impurities, odors, residual chlorine and other organic pollutants in the water through multi-stage filtration and activated carbon filtration, so that the water quality is cleaner and suitable for daily household use such as drinking, cooking, and washing.

[0044] The pure water function of the water purifier 8 means that it first uses multi-stage filtration to remove large particles, odors, residual chlorine and other organic pollutants in the water, and then further filters through a reverse osmosis membrane to remove trace bacteria, viruses and heavy metals in the water, and adjusts the pH of the water, thereby achieving high-purity water quality for production and manufacturing in laboratories, cosmetics, electronic products and other fields.

[0045] Therefore, the water treated by the water purifier 8 is divided into clean water and pure water. In the present application, the faucet includes a clean water faucet 6 and a pure water faucet 7. The clean water faucet 6 and the pure water faucet 7 are both connected to the water outlet of the water purifier 8, so that the clean water treated by the water purifier 8 is output through the clean water faucet 6, and the pure water treated by the water purifier 8 is output through the pure water faucet 7. The water receiving tank 2 receives the water output from the clean water faucet 6 and the pure water faucet 7, thereby making the application range of the water purifier demonstration system wider and more practical.

[0046] In this embodiment, the water receiving tank 2 includes a clean water tank 22 for receiving water output from the clean water faucet 6, a pure water tank 23 for receiving water output from the pure water faucet 7, and a partition 24 provided between the clean water tank 22 and the pure water tank 23, the partition 24 being used to separate the clean water tank 22 from the pure water tank 23. In the present application, the water receiving tank 2 includes the clean water tank 22, the pure water tank 23 and the partition 24, the clean water tank 22 is provided below the clean water faucet 6, and receives water output from the clean water faucet 6; the pure water tank 23 is provided below the pure water faucet 7, and receives water output from the pure water faucet 7.

[0047] The partition 24 is arranged between the clean water tank 22 and the pure water tank 23, and is used to separate the clean water tank 22 from the pure water tank 23. That is, when the water receiving tank 2 receives the water output by the clean water faucet 6 and the pure water faucet 7, the clean water output by the clean water faucet 6 is located in the clean water tank 22, and the pure water output by the pure water faucet 7 is located in the pure water tank 23. The two are separated by the partition 24 in the water receiving tank 2, so that the water purifier demonstration system can better display the working condition of the water purifier 8 and enhance the user's desire to buy.

[0048] In this embodiment, the clean water tank 22 receives the water output by the clean water faucet 6, the water circulation port 21 is set on the clean water tank 22, and the water inlet end of the water pump 1 is connected with the water circulation port 21, so that when the water pump 1 supplies water to the water purifier 8, the water in the clean water tank 22 is sucked into the water purifier 8, thereby realizing the recycling of water in this water purifier demonstration system and saving resources.

[0049] In this embodiment, the height of the partition 24 is less than the depth of the clean water tank 22 and the pure water tank 23. Since in this application, the water circulation port 21 is set on the clean water tank 22, the water pump 1 only sucks the water in the clean water tank 22 through the water circulation port 21. When demonstrating the pure water function of the water purifier 8, when the water output from the pure water faucet 7 reaches the upper limit of the water level of the pure water tank 23, it will overflow outward in the pure water tank 23, thereby affecting the on-site environment.

[0050] Therefore, in the present application, the height of the partition 24 is set to be smaller than the depth of the clean water tank 22 and the pure water tank 23. When demonstrating the pure water function of the water purifier 8, when the water output by the pure water faucet 7 reaches the upper limit of the water level in the pure water tank 23, it will flow from above the partition 24 to the clean water tank 22, and then be pumped into the water purifier 8 by the water pump 1. This can prevent the water in the pure water tank 23 from overflowing and affecting the on-site environment, and can also recycle the water in the pure water tank 23 to save resources, thereby making the water purifier demonstration system more practical.

[0051] It is foreseeable that: in actual implementation, a drain port can also be provided at the bottom of the pure water tank 23. When demonstrating the pure water function of the water purifier 8, the drain port is closed. When the water output from the pure water tap 7 reaches the upper limit of the water level of the pure water tank 23, it flows from above the partition 24 to the pure water tank 22, and then is sucked into the water purifier 8 by the water pump 1, which not only prevents the water in the pure water tank 23 from overflowing and affecting the on-site environment, but also allows the water in the pure water tank 23 to be recycled and save resources. After the demonstration, the drain port can be opened to transport the remaining water in the pure water tank 23 to the water tank for storage.

[0052] In this embodiment, a wastewater recovery port 25 is further provided on the clean water tank 22, and the wastewater pipe of the water purifier 8 is connected to the wastewater recovery port 25, so as to recover the wastewater generated in the water purifier 8 to the clean water tank 22. Since the water purifier 8 generates wastewater in addition to clean water and pure water during the water treatment process, the water purifier 8 is usually provided with a wastewater pipe for discharging the wastewater.

[0053] In the present application, a wastewater recovery port 25 is also provided on the clean water tank 22, and the wastewater pipe of the water purifier 8 is connected to the wastewater recovery port 25, so that the wastewater generated in the water purifier 8 flows into the clean water tank 22 through the wastewater pipe and the wastewater recovery port 25, and then the water pump 1 sucks the water in the clean water tank 22 through the water circulation port 21, thereby realizing the recycling of wastewater and further saving resources.

[0054] In this embodiment, a clean water faucet interface 26 and a pure water faucet interface 27 are provided on the water receiving tank 2. The clean water faucet 6 is installed above the clean water tank 22 through the clean water faucet interface 26, so that the clean water tank 22 can receive the water output by the clean water faucet 6; the pure water faucet 7 is installed above the pure water tank 23 through the pure water faucet interface 27, so that the pure water tank 23 can receive the water output by the pure water faucet 7, thereby facilitating the use of the water purifier 8 in an environment without water supply, thereby solving the problem that offline stores are limited by the lack of water source and cannot display the normal working conditions of the water purifier 8 during experience promotion, thereby enhancing users' desire to buy.
