Description

Technical Field

[0001] This utility model relates to the field of water purification device technology, specifically a novel water outlet pipeline system based on a desktop water purifier to solve the problem of excessively high TDS in the first cup of water. Background Technology

[0002] Desktop water purifiers combine water purification and drinking in one unit, offering convenient adjustment of water temperature and volume. The purified water produced after passing through a pre-filter, nanofiltration or reverse osmosis membrane, and a post-activated carbon filter is safe and stable. However, the water spout and upstream piping are constantly exposed to air, allowing organic pollutants and bacteria to contaminate the spout. Furthermore, the TDS value of the first cup of water dispensed after the purifier has been idle for a period of time will significantly increase, exceeding the standard, which may affect water safety.

[0003] Therefore, this utility model provides a novel water outlet pipeline system based on a desktop water purifier to solve the problem of excessively high TDS in the first cup of water, thereby addressing the aforementioned technical issues. Utility Model Content

[0004] Purpose of this utility model: To solve the problems in the existing technology where the water outlet and the preceding pipeline of the water purifier are exposed to the air for a long time, allowing organic pollutants and bacteria to contaminate the water outlet through the air; and the TDS value of the first cup of water dispensed after the water purifier has been idle for a period of time increases significantly and exceeds the standard, which has a certain impact on water safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel water outlet piping system based on a desktop water purifier to solve the problem of excessively high TDS in the first cup of water, comprising:

[0007] Raw water tank;

[0008] A filter module is provided, with a pre-module high-pressure pump installed between the filter module and the raw water tank. The filter module is used to filter the water in the circular raw water tank.

[0009] A pure water tank, wherein the pure water tank stores pure water filtered by the filter module;

[0010] An instant heating element, wherein the instant heating element is used to heat water pumped from a pure water tank;

[0011] A water tap alternation module is installed at the outlet of the instant heating pipe;

[0012] A cooling tank is used to collect and cool the water flowing out of the water tap alternation module after high-temperature disinfection.

[0013] Furthermore, the water tap alternation module includes;

[0014] Stepper screw motor;

[0015] A crank turntable is connected to a stepper screw motor via a connecting rod. One end of the connecting rod is mounted on the slider of the stepper screw motor, and the other end is fixed to the crank turntable. The crank turntable is driven to rotate by the stepper screw motor.

[0016] The solenoid valve includes a first solenoid valve and a second solenoid valve, which are respectively installed at both ends of the Y-shaped water outlet pipe.

[0017] The water outlet includes a first water outlet and a second water outlet, which are respectively disposed at both ends of the water outlet pipe connecting the first solenoid valve and the second solenoid valve. The water outlet pipe is supported externally by an extension rod.

[0018] The return water pipe is equipped with a first return water funnel and a second return water funnel at both ends, which are used to receive the high-temperature water flowing out of the first water outlet and the second water outlet, respectively. The return water pipe is connected to the cooling box.

[0019] Furthermore, the filtration module includes: a pre-filter composite filter, a reverse osmosis filter, and a post-activated carbon filter arranged in sequence.

[0020] Furthermore, the cooling box is equipped with a temperature sensor. When the temperature is below 30°C, the third solenoid valve is opened and the peristaltic pump is activated to pump water from the cooling box into the filter module.

[0021] Furthermore, the pure water tank is equipped with an ultraviolet lamp.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The high-temperature cleaning process for the water nozzles has been enhanced. Two water outlets and a return water reuse pipeline are provided, allowing the water nozzles to be used alternately. When the user presses the water outlet button, the internal water nozzles first undergo high-temperature water flow sterilization. Then, a stepper motor drives a crank-slider structure to place the sterilized water nozzles onto the user's water inlet. The return water flows back to the cooling tank through a funnel-connected pipeline. After the water temperature drops, it is pumped back to the original water tank by a peristaltic pump. The peristaltic pump ensures that the original water side is completely isolated from the cooling tank, preventing contamination of the return pipeline. Attached Figure Description

[0031] The novel water outlet pipeline system 13 based on the desktop water purifier in this embodiment, which solves the problem of excessively high TDS in the first cup of water, may further optionally include a filter module 16 comprising: a pre-filter composite filter, a reverse osmosis filter, and a post-activated carbon filter arranged in sequence.

[0032] The novel water outlet pipeline system 13 based on the desktop water purifier in this embodiment can be further optionally configured such that when the temperature is below 30°C, the third solenoid valve 15 is opened and the peristaltic pump 11 is activated to pump the water in the cooling tank 9 into the filter module 16.

[0034] Working principle: 1. When the user presses the water outlet button, the system starts working. The second solenoid valve 3 opens, and pure water flows through the instant heating tube 1 for heating. After passing through the second solenoid valve 3, it passes through the second water outlet 5 for high-temperature sterilization. It then flows into the second return water funnel 6 and enters the return water pipe 14, flowing into the cooling tank 9. After high-temperature sterilization, the second solenoid valve 3 closes, the lead screw stepper motor starts, and the slider moves to the end of the motor. Through the connecting rod, the crank turntable 1203 is driven to rotate counterclockwise, which drives the first water outlet 4 fixed on the extension rod to rotate to the first return water funnel 8. The sterilized second water outlet 5 rotates to the water outlet 7 of the water purifier, and the second solenoid valve 3 starts to dispense water.

[0035] 2. The next time the user presses the water dispensing button, the first solenoid valve 2 opens, and pure water flows through the instant heating element 1 for heating, then through the first solenoid valve 2, and then through the first water outlet 4 for high-temperature sterilization. It then flows into the first return water funnel 8 and into the return water pipe 14, before flowing into the cooling tank 9. After sterilization, the first solenoid valve 2 closes, the lead screw stepper motor starts, and the slider moves to the front of the motor, driving the crank turntable 1203 to rotate clockwise via the connecting rod. This causes the second water outlet 5, fixed on the extension rod, to rotate to the second return water funnel 6, and the first water outlet 4 to the water outlet 7 of the water purifier. The first solenoid valve 2 then opens, and water begins to flow. This cycle repeats.

[0036] 3. A PT100 temperature sensor 10 is connected inside the cooling tank 9. When the detected temperature is below 30°C, the peristaltic pump 11 is turned on to pump the return water in the cooling tank 9 back to the original water tank 19.
