Description

Technical Field

[0001] This utility model relates to the field of water purification device technology, and in particular to a water purifier with a kettle that is electric, pump-free, and has no built-in kettle. Background Technology

[0002] Reverse osmosis water purifiers are drinking water devices used to provide purified water, and are widely used in homes, offices, and public service venues. Currently, reverse osmosis water purifiers are equipped with booster pump systems, but these systems increase production costs and maintenance difficulties. Additionally, the booster pumps generate significant noise during operation, affecting the user experience. Furthermore, reverse osmosis water purifiers have the problem of low desalination rates in the first cup of water after overnight storage. The current solution is to flush the purifier with a large amount of water when it is not in operation, resulting in significant water waste.

[0003] On the other hand, for reverse osmosis water purifiers, the lack of a booster pump system will result in a relatively slow water output speed. It will also be impossible to control the automatic start and stop of the water purification process from the filter cartridge, making the water purifier lack intelligent and stable water output function. It is also necessary to realize water leakage protection for the water purifier in the absence of electricity, so that the water circuit of the water purifier can be automatically controlled without electricity. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a water purifier with a kettle that is electric-free and pump-free. It can automatically start and stop water production and output without the need for a booster pump system or electricity, ensuring the quality of the output water and automatically controlling water leakage without the need for electricity.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A water purifier with a kettle and no electricity or pump includes a housing. Inside the housing are a filter assembly, a water circuit board, a mechanical inlet valve, a leak protector, a kettle, and a level control component. The water circuit board has a tap water inlet and a wastewater inlet, and multiple independent water pipes. The water circuit board connects to the filter assembly via different water pipes to form different water paths. The water circuit board is connected to the kettle via water pipes. The kettle is connected to the level control component via water pipes. The level control component is fixedly mounted to the mechanical inlet valve. The opening and closing of the mechanical inlet valve is controlled by the liquid level in the level control component. The mechanical inlet valve is located on the water pipe between the water circuit board and the filter assembly. A leak protector is installed on the water pipe between the water circuit board and the mechanical inlet valve. The leak protector cuts off the water path due to buoyancy.

[0007] Compared with the prior art, this utility model uses a kettle and a liquid level control component that are in a communicating vessel relationship to indirectly control the opening and closing of the mechanical inlet valve according to the level of purified water stored in the kettle. This automatically controls the water supply path to the filter element assembly, eliminating the need for a booster pump and enabling automatic water production start and stop without electricity. Multiple independent water pipes on the water circuit board connect different water circuit relationships, ensuring independent water flow. This separates the kettle and filter element assembly, preventing the purified water in the kettle from being permeated by overnight water in the filter element assembly. The included leakage protector can automatically control the opening and closing of the water circuit in the absence of electricity.

[0008] Preferably, the liquid level control component includes a liquid level tank, a first float, a rocker arm, and a magnet. A water tank pipe is provided at the bottom of the liquid level tank, connecting it to the kettle via a water passage pipe. The first float is housed within the liquid level tank and floats up and down with the water level. The mechanical inlet valve includes a main body located outside the liquid level tank and a mechanical trigger rod located inside the tank. A magnet is mounted on the first float. When the first float rises and falls around the rocker arm with changes in the water level in the liquid level tank, the magnet moves closer to or away from the mechanical trigger rod to control the opening and closing of the mechanical inlet valve. The height of the liquid level tank within the housing is related to the water level line in the kettle, ensuring that when the purified water in the kettle is below the water level line, the water level in the liquid level tank also drops. This causes the magnet to move closer to the mechanical trigger rod as the water level drops, and the mechanical trigger rod, influenced by the magnet, controls the opening of the mechanical inlet valve to replenish purified water in the kettle and restore the stored purified water.

[0009] Furthermore, a regulating valve is installed on the water pipe between the kettle and the liquid level control component to regulate the amount of purified water flowing from the kettle into the liquid level tank. By installing the regulating valve, manual intervention can be performed when there is a large difference in liquid level between the liquid level tank and the kettle to prevent water overflow.

[0010] Furthermore, the leakage protector includes a second float, a slide, a first inlet and a second outlet. The first inlet and the second outlet form a connected protective water passage. The second float moves up and down in the slide with the buoyancy of the water while controlling the opening and closing of the protective water passage.

[0011] Furthermore, the second float has an inverted T-shaped longitudinal section, including an integrally formed bottom floating surface and an upper float rod. A protective cavity is provided at the lower end of the leak protector to accommodate the floating surface. The slide is perpendicular to the protective water passage, and the float rod slides up and down within the slide. The diameter of the float rod is larger than that of the protective water passage. After water accumulates at the bottom of the water purifier, the second float rises and blocks the protective water passage, preventing water from being supplied to the mechanical inlet valve and shutting off the water supply to the water purifier, thus preventing further leakage.

[0012] Furthermore, the filter element assembly includes a fixedly connected composite filter element and a filter base. The bottom of the composite filter element is connected to the filter base. The filter base has independent waste outlet, clean outlet, and water supply outlet, which are respectively connected to different water pipes on the water circuit board. A check valve is installed on the clean outlet. The different outlets on the filter base connected to different water pipes on the water circuit board allow different types of water to flow through different water circuits, ensuring clean and safe water use. The check valve prevents the purified water produced by the filter element assembly from flowing back into the filter element assembly.

[0013] Furthermore, the composite filter element is composed of a four-layer filtration structure, consisting of a pleated PP filter element, a carbon fiber layer, a reverse osmosis membrane, and a carbon rod layer from the inside out. The inner wall of the kettle is coated with an antibacterial material.

[0014] Furthermore, a three-way connector is provided between the kettle and the mechanical water inlet valve. The three-way connector includes a first connector, a second connector, and a third connector. The first connector is connected to the kettle, the second connector is connected to the water circuit board, and the third connector is connected to the liquid level control component. The diameter of the first connector is larger than that of the second and third connectors.

[0015] Furthermore, a regulating valve is installed on the wastewater outlet to control the discharge of wastewater from the water purifier.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By using a kettle and a liquid level control component that are connected by a communication vessel, the mechanical inlet valve is opened and closed indirectly by mechanical control based on the level of purified water stored in the kettle. This automatically controls the water supply path to the filter element assembly and automatically adjusts the opening and closing of the mechanical inlet valve to complete the automatic water production start and stop. This enables automatic start and stop water production in the absence of electricity and pump.

[0018] 2. Multiple independent water pipes are set on the water circuit board to connect different water circuits, making the water flow independent and separating the water jug ​​and filter assembly. This prevents the purified water in the water jug ​​from being permeated by overnight water in the filter assembly, resulting in a high desalination rate in the water jug ​​and eliminating the need for large amounts of water to rinse it, thus preventing stagnant water.

[0019] 3. The added leak protector can prevent water from accumulating at the bottom of the water purifier. The second float will rise and block the water passage, preventing the mechanical inlet valve from supplying tap water and shutting off the water supply to the water purifier. The water purifier will not continue to leak. This process does not require electricity and only uses the buoyancy generated by the leak to cut off the water supply. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. The components of this utility model, typically described and shown in the drawings herein, can be arranged and designed in various different configurations. Therefore, the following detailed description of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] In this article, purified water refers to water that has undergone multiple filtrations by the filter cartridge assembly and is suitable for direct drinking and heating. Wastewater refers to tap water that cannot be used after being filtered by the filter cartridge assembly.

[0032] To address the problem in the background technology that existing water purifiers, without a booster pump system, cannot automatically start and stop water production and output in the absence of electricity and pump, thus ensuring water quality and eliminating the low desalination rate of the first cup of water from overnight water.

[0033] Please see Figure 1-2 This utility model proposes a water purifier with a kettle that is electric and pump-free, and includes a housing 1. Inside the housing 1, a filter assembly 2, a water circuit board 4, a mechanical inlet valve 6, a check valve 12, a kettle 3, a level control assembly 5, and a leak protector 7 are arranged in a reasonable manner. The mechanical inlet valve 6 and the level control assembly 5 are fixed together by bolts and nuts. The kettle 3 and the level control assembly 5 have a communicating vessel relationship, ensuring that the water level in the kettle 3 is synchronized with the water level in the level control assembly 5. The system is highly interconnected, and the opening and closing of the mechanical inlet valve 6 is indirectly controlled by the change in liquid level through mechanical linkage, so as to achieve automatic start and stop of water production and output in the water circuit. On the other hand, the water leakage protector 7 is installed on the water pipe between the water circuit plate 4 and the mechanical inlet valve 6. Its bottom floating surface 701 is housed in the bottom of the housing 1. When the water purifier leaks, the accumulated water will gather at the bottom of the housing 1, lifting the floating surface 701 at the bottom of the water leakage protector 7. The float rod 702 rises to cut off the water circuit and prevent water leakage.

[0034] Please see Figure 3 Overall structure diagram of water circuit board and Figure 6The diagram shows the assembly of the filter base and check valve. The water circuit board 4 has multiple independent water pipes for different connections, forming different water circuits through connections with different components of the water purifier. Specifically, the first water pipe 401 on the water circuit board 4 connects to the tap water valve 10 and the mechanical inlet valve 6, introducing tap water into the mechanical inlet valve 6. The second water pipe 402 connects to the wastewater regulating valve 11 and the first waste outlet 407. The third water pipe 403 connects to the first water supply port 405 and the mechanical inlet valve 6. The fourth water pipe 404 connects to the filter element assembly 2 through the first outlet 406 and to the kettle 3 through the tee connector 8. The first water supply port 405 on the water circuit board 4 is connected to the second water supply port 202 of the filter base 202. 21 is connected to allow tap water to flow into the filter element assembly 2. The first outlet 406 is connected to the second outlet 2022 of the filter base 202, which is used to allow the filtered water to flow from the filter base 202 to the water circuit plate 4 and then into the water tank 3. A check valve 15 is set between the first outlet 406 and the second outlet 2022 to control the water to flow only through the filter base 202 to the water circuit plate 4 and not back from the water circuit plate 4 to the filter base 202, thus ensuring the separation of the functions of filtering and storing purified water. The first waste outlet 407 is connected to the second waste outlet 2023 of the filter base 202, which is used to discharge the filtered wastewater from the water purifier. The wastewater discharge is controlled by the regulating valve 13 for centralized treatment.

[0035] Please see Figure 4 Overall cross-sectional view of the liquid level control component 2 and Figure 5The assembly cross-sectional view shows that the liquid level control component 5 includes a liquid level tank 501, a vent 502, a first float 503, and a rocker arm 504. The bottom of the liquid level tank 501 has a hole connecting to a water tank pipe 506, which in turn connects to a kettle 3. A regulating valve 9 is installed on the water pipe to control the water level in and out of the liquid level tank 501. Normally, the regulating valve 9 is not needed. When the water level in the liquid level tank 501 is high and prone to overflow, the regulating valve 9 closes the water passage. The rocker arm 504 is integrally connected to the first float 503. The liquid level tank 501... A fixing part 505 is provided on the side wall, so that the first float 503 is raised and lowered by buoyancy control around the fixing part 505 via the rocker arm 504. A limiting part 5031 is provided at the lower part of the first float 503. The mechanical water inlet valve 6 is fixed to the outer wall of the liquid level tank 501 by bolts, and one end extends into the liquid level tank 501 through the opening on the side wall. The part extending into the liquid level tank 501 is a mechanical trigger rod 603. An anti-overflow ring is provided between the mechanical trigger rod 603 and the wall of the liquid level tank 501 to prevent leakage. The mechanical trigger rod 603 and the limiting part Limiting valve 5031: A magnet is installed on limiting part 5031. The portion of mechanical water inlet valve 6 located outside liquid level tank 501 connects to the second water inlet 601 and the second water outlet 602. When the mechanical trigger rod 603 is affected by the magnet approaching or moving away, it controls the opening and closing of the water passage connecting the second water inlet 601 and the second water outlet 602 on mechanical water inlet valve 6. After water in kettle 3 flows into liquid level tank through water tank pipe 506, the first float 503 rises. When the magnet rises and moves away from mechanical trigger rod 603, mechanical water inlet valve 6 is closed. The water passage between the second inlet 601 and the second outlet 602 prevents tap water from flowing into the filter assembly 2 to produce purified water. Conversely, when the water level in the level tank 501 drops with the water level in the kettle 3, the first float 503 descends, the magnet approaches the mechanical trigger rod 603, and the mechanical inlet valve 6 controls the opening of the water passage between the second inlet 601 and the second outlet 602. Tap water flows into the filter assembly 2 through the mechanical inlet valve 6 to produce purified water, and then replenishes the kettle 3 with purified water to restore the stored purified water. When purified water is needed, it is poured directly from the kettle 3 into a cup.

[0036] See Figure 8 The three-way connector 8 is located at the bottom of the kettle 3, including a first connector 801 with a larger diameter and a second connector 802 and a third connector 803 with smaller diameters. The first connector 801 is connected to the bottom of the kettle 3. The second connector 802 is connected to the liquid level control component 5 through the water tank pipe 506 at the bottom of the liquid level tank 501. The third connector 803 is connected to the fourth water pipe 404 for introducing filtered purified water into the kettle. In addition, a regulating valve 9 or a check valve 12 can be installed on the second connector 1002 and the third connector 1003 to control the opening and closing of the water circuit.

[0037] A regulating valve 9 is installed on the water pipe between the kettle 3 and the liquid level control component 5 to regulate the amount of purified water flowing from the kettle 3 into the liquid level tank 501. By installing the regulating valve 9, manual intervention can be performed when there is a large difference in liquid level between the liquid level tank 501 and the kettle 3 to prevent excessive water production and overflow into the kettle 3.

[0038] Please see Figure 7 The longitudinal section view of the water leakage protector 7 shows that the water leakage protector 7 is installed in the water passage between the water passage plate 4 and the mechanical inlet valve 6, controlling the tap water supply to the mechanical inlet valve 6. The water leakage protector 7 includes a protective water passage 702 formed by a first inlet 703 and a first outlet 704, with a protective cavity 706 at its lower part. It also includes a second float 701 that rises and falls within the protective cavity 706 under buoyancy. The second float includes a lower floating surface 7011 and an upper float rod 7012, which are integrally formed, making the longitudinal section of the second float... The device is T-shaped, and a slide 705 is vertically installed inside the leak protector 7, which communicates with the water circuit protection channel 702. When the float 7011 rises and falls in the protection cavity 706, it drives the float rod 7012 to rise and fall in the slide 705. The diameter of the float rod 7012 is larger than that of the water circuit protection channel 702. When the water purifier leaks, the water will collect at the bottom of the housing 1, lifting the float 701 at the bottom of the leak protector 7. The float rod 702 rises in the slide 705 to block and cut off the water circuit protection channel 702, stopping the water supply to the mechanical water inlet valve 6 and preventing further leakage.

[0039] The liquid level control component 5 is located between the kettle 3 and the filter element component 2. This arrangement makes the overall structure of the water purifier more compact and reduces the overall size of the water purifier.

[0040] The filter element assembly 2 of this utility model includes a composite filter element 201 and a filter base 202. The bottom of the composite filter element 201 is connected to the filter base 202. The composite filter element 201 is composed of a four-layer filtration structure, which consists of a pleated PP filter element, a carbon fiber layer, a reverse osmosis membrane, and a carbon rod layer from the inside to the outside. The inner wall of the water bottle 3 is coated with an antibacterial material.

[0041] Please see Figure 9 The water circuit diagram of this utility model water purifier shows that the water purifier can be used in the following water supply modes:

[0042] Mode 1: Tap water flows through tap water valve 10, through the first water pipe 401, into the mechanical inlet valve 11, and then through the mechanical inlet valve 6 to the third water pipe 403 to enter the filter element assembly 2 for water supply.

[0043] Mode 2: Wastewater treated by filter element 2 flows through the first waste outlet 407 and is discharged through the second water pipe 402;

[0044] Mode 3: The purified water filtered by the filter element assembly 2 flows through the check valve 7, the first outlet 406, the fourth water pipe 404, and the tee connector 10 into the kettle 3 for storage.

[0045] This utility model uses a kettle 3 and a liquid level control component 5, which are in a communicating vessel relationship, to control the opening and closing of the mechanical inlet valve 6 indirectly according to the water level of the purified water stored in the kettle 3. This automatically controls the water supply path to the filter element assembly 2 and automatically adjusts the opening and closing of the mechanical inlet valve 6 to complete the automatic water production start and stop, thus realizing automatic start and stop water production without a pump.

[0046] The water circuit board 4 is equipped with multiple independent water circuit pipes to connect different water circuits, making the water flow independent and separating the water jug ​​3 and the filter element assembly 2. This prevents the purified water in the water jug ​​3 from being penetrated by the overnight water in the filter element assembly 2, resulting in a high desalination rate in the water jug ​​3. It also eliminates the need for rinsing with large amounts of water and prevents the presence of stagnant water.

[0047] The added water leakage protector 7 can prevent water from accumulating at the bottom of the water purifier. The second float 701 will rise and block the water passage, preventing the mechanical water inlet valve 6 from supplying tap water and shutting off the water circuit of the water purifier. The water purifier will not continue to leak. This process does not require electricity and only requires the buoyancy generated by the leakage to cut off the water circuit.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
