Description

Technical Field

[0001] This utility model relates to the field of direct drinking water technology, specifically to a direct drinking water device with a segmented purification process. Background Technology

[0002] Direct drinking water equipment is a point-of-use water purification system that directly treats tap water or other water sources into drinking water that meets drinking standards, allowing for direct consumption without additional boiling. Its core function is to remove harmful substances from the water through multi-stage filtration and purification technology. Common filtration technologies include PP cotton filtration, activated carbon adsorption, and reverse osmosis membrane separation. PP cotton can filter large particles such as sediment and rust, activated carbon can adsorb residual chlorine, odors, and some organic matter, while reverse osmosis membranes can retain tiny contaminants such as bacteria, viruses, and heavy metal ions.

[0003] In areas with poor water quality, tap water often contains a large amount of sediment, rust, colloidal impurities, and microorganisms. When directly connected to a water purifier, these contaminants quickly adhere to the surface of the filter element. This is especially true for PP cotton filters used as pre-filters, which can become clogged with impurities in a short time, leading to a significant decrease in water flow or even complete blockage. Users are forced to frequently stop the purifier to replace the filter, disrupting daily water use and significantly increasing maintenance costs. If not replaced in time, clogged filters can also breed bacteria, further affecting the quality of the output water. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a direct drinking water device with a pretreatment structure that performs multi-level filtration to prevent rapid clogging of the filter element, and has a segmented purification process.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a direct drinking water device with a segmented purification process, comprising:

[0006] Cabinet;

[0007] The coarse filter tank is fixed on one side of the cabinet, with an inlet at the top and multiple filter discs inside, with the mesh size of the filter discs increasing from top to bottom.

[0008] The processing box is fixedly installed inside the cabinet. Its upper wall is connected to the lower end of the side wall of the coarse filter tank through a water inlet pipe. The inside is arranged from top to bottom as a PP cotton filter element, an activated carbon filter element and a reverse osmosis membrane filter element. A water pump is installed on the water inlet pipe.

[0009] The water intake tank is fixedly installed on the side of the cabinet away from the coarse filter tank. The upper part of the interior is provided with a water storage chamber. The water storage chamber is connected to the lower end of the side wall of the treatment tank through a second water inlet pipe. A second water pump is provided on the second water inlet pipe. A heater is built into the water storage chamber. The side wall of the water intake tank is provided with a treatment status display panel and a heating status display panel. A water intake slot is provided in the middle. A water intake button is provided at the upper edge of the water intake slot.

[0010] Furthermore, the upper end of the coarse filter tank is detachably equipped with a sealing top plate.

[0011] Furthermore, the side wall of the processing box is provided with a loading and unloading port for matching PP cotton filter cartridges, activated carbon filter cartridges and reverse osmosis membrane filter cartridges, and the loading and unloading port is provided with a sealing cap.

[0012] Furthermore, flow sensors are fixedly installed on the inner wall of the treatment chamber below the PP cotton filter, activated carbon filter, and reverse osmosis membrane filter, and the flow sensors are electrically connected to the treatment status display panel.

[0013] Furthermore, the heating status display panel is electrically connected to the heater.

[0014] Furthermore, a drain tray is provided on the bottom surface of the water intake trough.

[0015] Compared with existing technologies, the advantages of this invention are as follows: The equipment first utilizes a multi-layered filter disc in the coarse filtration stage, with the filter pore size increasing from top to bottom, to progressively filter impurities of different particle sizes in the water. Large particles are intercepted first, followed by smaller particles, preventing impurities from directly entering subsequent treatment stages. After this pretreatment, the impurities in the water entering the treatment tank are significantly reduced. Subsequent PP cotton filters, activated carbon filters, and reverse osmosis membrane filters do not need to frequently filter large amounts of impurities, thus reducing the probability of filter clogging, extending filter lifespan, and lowering maintenance frequency and costs.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Combined with appendix Figure 1Appendix Figure 2 Appendix Figure 4 A direct drinking water device with a segmented purification process includes: a cabinet 1; and a coarse filter tank 2, fixedly mounted on one side of the cabinet 1, with a water inlet at the top and multiple filter discs 3 inside, the mesh size of the filter discs 3 increasing from top to bottom. The coarse filter tank 2 has a detachable sealing top plate 15 at its upper end, allowing for easy opening and replacement or cleaning of the multiple filter discs 3 without disassembling the entire tank, significantly simplifying maintenance. Simultaneously, the sealed design prevents impurities from entering, ensuring the filtration effect of the coarse filtration stage.

[0023] Combined with appendix Figure 1 Appendix Figure 2 The treatment box 4 is fixedly installed inside the cabinet 1. Its upper wall is connected to the lower end of the side wall of the coarse filter tank 2 through a water inlet pipe 5. The inside is arranged from top to bottom with PP cotton filter element, activated carbon filter element and reverse osmosis membrane filter element. A water pump 6 is installed on the water inlet pipe 5. The side wall of the treatment box 4 is provided with a pick-up and drop port for matching PP cotton filter element, activated carbon filter element and reverse osmosis membrane filter element. The pick-up and drop port is provided with a sealing cover 16. When replacing PP cotton filter element, activated carbon filter element and reverse osmosis membrane filter element, there is no need to disassemble the entire treatment box 4. The operation can be carried out directly through the pick-up and drop port, which improves the filter element replacement efficiency. The sealing cover 16 can prevent water leakage or contamination during the purification process.

[0024] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The water intake tank 7 is fixedly installed on the side of the cabinet 1 away from the coarse filter tank 2. An internal water storage chamber is located at the upper end of the tank. This chamber is connected to the lower side wall of the treatment tank 4 via a second water inlet pipe 8. A second water pump 9 is installed on the second water inlet pipe 8. A heater 10 is built into the water storage chamber. A treatment status display panel 11 and a heating status display panel 12 are located on the side wall of the water intake tank 7. Flow sensors are fixedly installed on the inner wall of the treatment tank 4 below the PP cotton filter, activated carbon filter, and reverse osmosis membrane filter. These flow sensors are electrically connected to the treatment status display panel 11, allowing real-time monitoring of the water flow below the three types of filters. If a filter becomes clogged, causing abnormal flow, the treatment status display panel 11 will promptly remind the user to replace it, preventing filter failure from affecting the purification effect. The heating status display panel 12 is electrically connected to the heater 10, allowing for a direct view of the water heating status in the storage chamber, such as whether heating is in progress or whether the preset temperature has been reached, preventing scalding or receiving unheated water due to blindly taking water.

[0025] Combined with appendix Figure 1 Appendix Figure 3 The water tank 7 has a water inlet 13 in the middle, and a water dispensing button 14 is located at the upper edge of the water inlet 13. The bottom surface of the water inlet 13 is provided with a drain tray 17, which can catch water droplets when dispensing water and prevent water from flowing to the outside of the equipment or the ground, causing wetness and slipping.

[0026] The specific implementation method of this utility model is as follows: The water to be purified is connected to the inlet of the coarse filter tank 2 on one side of the cabinet 1. The water undergoes preliminary filtration in the coarse filter tank 2 through multiple filter discs 3, and large particles of impurities are intercepted. Then, the water pump 6 on the water inlet pipe 5 is started, and the filtered water is transported to the treatment tank 4 inside the cabinet 1 through the water inlet pipe 5. It then undergoes deep purification by passing through the PP cotton filter, activated carbon filter, and reverse osmosis membrane filter in the treatment tank 4 in sequence, removing fine impurities, odors, and harmful substances. After purification is completed, the water pump 9 on the water inlet pipe 8 is turned on, and the water is injected into the water storage chamber at the upper end of the water intake tank 7 through the water inlet pipe 8. If hot water is needed, the heater 10 in the water storage chamber can be started, and the heating status can be viewed through the heating status display panel 12 on the side wall of the water intake tank 7. At the same time, the flow sensor on the inner wall of the treatment tank 4 monitors the water flow in real time, and the data is fed back to the treatment status display panel 11 for easy viewing of the filter status. When taking water, press the water taking button 14 on the upper edge of the water taking trough 13 to collect water. The drain tray 17 inside the water taking trough 13 can catch dripping water droplets to prevent the ground from getting wet.
