Description

Technical Field

[0001] This invention relates to the field of water filtration equipment technology, and more specifically, to a rocker-type cutoff water purification device and its application. Background Technology

[0002] A water purifier is a device that filters and purifies water. As people's demands for quality of life increase, small water purifiers suitable for home use are becoming increasingly popular. Current water purification devices include water purifier tanks that do not require electricity and electric machine-type water purifiers. Water purifier tanks that do not require electricity generally use a built-in filter cartridge to filter the water; however, this filtration method can only remove large impurities and is not suitable for deeper water quality regulation.

[0003] To obtain better quality purified water, electric mechanical water purifiers are usually required. These purifiers use electrically driven power devices such as pumps to control the water inlet and outlet. Sometimes, due to power or water pressure issues, the water inlet and outlet cannot be reliably controlled, rendering the purifier unusable. In addition, the water purifier is noisy when it is powered on. Therefore, there is an urgent need for a mechanical water purifier that can achieve water purification without electricity.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a rocker-type shut-off water purification device and its application, which can automatically control the opening and closing of the water path during the filtration process, requires no electricity, has a simple structure, and high reliability.

[0006] The embodiments of the present invention are implemented as follows:

[0007] In a first aspect, the present invention provides a rocker-type cut-off water purification device, comprising a water flow cut-off unit, a water filtration unit, and a water storage unit connected in sequence.

[0008] The water flow interruption unit includes an inlet control valve and a control valve on / off assembly. The inlet control valve is connected to the water filter unit through a pipe. Therefore, water does not pass through the control valve on / off assembly during the process of flowing from the water flow interruption unit to the water filter unit. Instead, it flows directly from the inlet water passage of the inlet control valve to the water filter unit.

[0009] The control valve on / off assembly includes a mounting base, a counterweight, an on / off control water tank, and a connector. The connector is rotatably connected to the mounting base and can rotate relative to the mounting base. The rotation is centered on a fixed point between the connector and the mounting base.

[0010] The counterweight and the on / off control water tank are fixed to both sides of the mounting base by connectors. Therefore, the counterweight, the on / off control water tank and the connectors form a seesaw structure. The position of the counterweight and the on / off control water tank is controlled according to the gravity difference between the two ends of the seesaw.

[0011] The counterweight is positioned at intervals corresponding to the inlet control valve, and its contact with the valve is selective. This selective contact can be understood as follows: because the counterweight, the on / off control tank, and the connecting parts form a seesaw structure, when the inlet control valve is above the counterweight and the weight of the on / off control tank is greater than the weight of the counterweight, the counterweight contacts the inlet control valve, ensuring the water inlet path remains unobstructed. When the inlet control valve is below the counterweight and the weight of the on / off control tank is less than the weight of the counterweight, the counterweight contacts the inlet control valve, ensuring the water inlet path remains unobstructed.

[0012] The first inlet of the on / off control water tank is connected to the inlet of the water storage unit, and when the counterweight is far away from the water inlet control valve, the first inlet of the on / off control water tank and the water storage warning line of the water storage unit are on the same plane.

[0013] Since the first water inlet serves to connect with the water storage unit, the on / off control system forms a communicating vessel between the water tank, the water storage unit, and the connecting pipes. The water level in the water storage unit, where the filtered water is stored, can be determined by controlling whether there is water in the tank and how high or low the water level is once water is present. To facilitate adjustment of the filtration progress, a water level warning line can be pre-set in the water storage unit. When the water level reaches the warning line, the water supply to the filtration unit should be shut off to prevent overflow due to excessive water storage in the storage unit.

[0014] Therefore, the weight of the counterweight is related to the position and on / off process of the inlet control valve. If the inlet control valve is closed after contact and open when not in contact, the weight of the counterweight and the position of the inlet control valve can be adjusted according to the actual situation.

[0015] In some embodiments of the present invention, water flows into the filtration unit from the inlet control valve of the water flow cut-off unit for filtration. The filtered water flows from the filtration unit to the storage unit. Since the on / off control water tank is connected to the inlet of the storage unit, the amount of water stored in the storage unit can be determined by the amount of water in the on / off control water tank. By setting the first inlet of the on / off control water tank to be on the same plane as the water storage warning line of the storage unit, when water begins to enter the on / off control water tank, it indicates that the amount of water in the storage unit has reached the water storage warning line. As the amount of water entering increases, the overall weight of the on / off control water tank increases. When the total weight of the on / off control water tank and the water inside it exceeds the weight of the counterweight, the counterweight can be lifted by the connector so that the counterweight does not contact the inlet control valve. The valve core of the inlet control valve rebounds to close the inlet water passage, and the water supply to the filtration unit is cut off. When the water in the storage unit is used until it falls below the water level warning line, the water level in the on / off control tank drops synchronously, causing the tank's weight to decrease. When the total weight of the on / off control tank and its contents is less than the weight of the counterweight, the counterweight, through a connector, tilts the on / off control tank upwards and then downwards, bringing it into contact with the inlet control valve. At this point, the inlet water passage of the inlet control valve opens, and water re-enters the filtration unit for filtering. This cycle repeats, achieving automated water purification and preventing overflow due to prolonged filtration and unused purified water.

[0016] Since the device of the present invention can achieve automated control of the water filtration process without electricity, it is understood that the water inlet path of the water inlet control valve of the present invention should be a continuously connected path, and the water inlet path will only be disconnected when it is necessary to stop water filtration.

[0017] In an optional implementation, the on / off control water tank can be a closed tank or an open tank, preferably a closed tank.

[0018] In an optional implementation, the sealed on / off control water tank can be a one-piece sealed structure or a split structure consisting of a tank body and a cover body.

[0019] In an optional implementation, for ease of installation, the top of the mounting base is on the same plane as the top of the water storage unit.

[0020] In an optional embodiment, the inlet control valve includes a valve core and a valve body, with the valve core disposed within the valve body. A fixing member is provided on the counterweight, and when the counterweight contacts the inlet control valve, the fixing member secures the valve core. In the above embodiment, the structure is designed so that the inlet water passage is unobstructed when the valve core of the inlet control valve is extended; therefore, after the fixing member secures the valve core, the inlet water passage remains unobstructed.

[0021] The valve core of the inlet control valve includes a valve core housing, a valve core body housed within the valve core housing, and a valve core elastic element. The valve core elastic element is fixed to the side of the valve core body away from the valve body. The valve core elastic element can apply elastic force to the valve core to ensure that the valve core can open and close the inlet water passage within the valve body.

[0022] The valve core controls the opening and closing of the water inlet path within the inlet control valve. When the water inlet path is open, the valve core is fixed by the fixing component, causing the counterweight to contact the inlet control valve. When water enters the tank and its weight exceeds the counterweight, the counterweight rises and moves away from the inlet control valve. The valve core then disengages from the fixing component and moves towards the water inlet path, blocking it and effectively cutting off the water inlet. When the water level in the tank decreases and its weight is less than the counterweight, the counterweight descends and moves towards the inlet control valve. The valve core is then fixed by the fixing component, opening the inlet path and allowing water to enter.

[0023] In an optional implementation, the water inlet control valve is a solenoid valve, and the fixing component is a magnetic component.

[0024] In an optional embodiment, the inlet control valve further includes a valve core elastic element, which is disposed within the valve body and fixed to the valve core, and is located at the end of the valve core near the counterweight. The valve core elastic element can push the valve core to move.

[0025] In an optional implementation, to avoid excessive weight of the counterweight or the water tank used for on / off control leading to a short lifespan for the connector, the connector is a zigzag-shaped connector, with the midpoint of the zigzag line rotatably connected to the mounting base. The zigzag-shaped connector allows the heavier end to experience an upward force when it sinks, parallel to the direction of the connector, thus extending its service life.

[0026] In an optional embodiment, the counterweight is located below the on / off control water tank, and the weight of the counterweight is greater than the weight of the on / off control water tank but less than the weight of the on / off control water tank when it is full of water. In other embodiments, the counterweight can also be located above the on / off control water tank, as long as contact control on / off can be achieved.

[0027] Understandably, because the counterweight is located below the on / off control tank, there is no water in the on / off control tank during normal filtration. When it is necessary to shut off the water inlet, the water level in the storage unit rises, causing the on / off control tank to go from empty to filled with water, and the water level gradually increases. When the total weight of the on / off control tank after filling with water exceeds the counterweight, the entire on / off control tank moves downward, causing the water level in the on / off control tank to be inconsistent with the water level in the storage unit. The water level in the on / off control tank is lower. To balance this water level difference, the water level in the storage unit will drop slightly, forming a buffer zone for clean water storage. During the downward movement of the entire on / off control tank, the counterweight moves upward and disengages from the valve core of the inlet control valve. The valve core moves towards the inlet water path due to the rebound force of the valve core elastic element, thus shutting off the inlet water path and preventing clean water from overflowing from the storage unit.

[0028] In an optional implementation, the weight of the counterweight is greater than the weight of the on / off control water tank, but less than the total weight of the on / off control water tank, which has a water volume of 1 / 5 to 4 / 5 of the on / off control water tank volume.

[0029] In an optional implementation, the weight of the counterweight is greater than the weight of the on / off control water tank, but less than the total weight of the on / off control water tank, which has a water volume of 1 / 3 to 2 / 3 of the on / off control water tank volume.

[0030] In an optional implementation, the weight of the counterweight is greater than the weight of the on / off control water tank, but less than the total weight of the on / off control water tank when the water volume is half the volume of the on / off control water tank.

[0031] The above are just examples of possible weight ranges for the counterweight in this invention. The specific weight setting of the counterweight can be set according to the actual situation. For example, the weight of the counterweight can be set according to factors such as the water filtration capacity of the water filtration unit, the position of the water storage warning line of the water storage unit, and the capacity of the on / off control water tank.

[0032] In an optional implementation, the water filtration unit is a filter, and the water storage unit is a water storage tank.

[0033] Preferably, any commercially available filter can be used, and the shape and size of the water storage tank can be conventionally set according to specific needs.

[0034] Secondly, the present invention provides an application of the rocker-type cut-off water purification device as described in any of the foregoing embodiments in the field of water purification or water filtration.

[0035] The beneficial effects of the embodiments of the present invention are:

[0036] This invention provides a rocker-type shut-off water purification device and its application. Water flows into the filtration unit from the inlet control valve of the water flow shut-off unit for filtration. The filtered water flows from the filtration unit to the storage unit. Since the shut-off control tank is connected to the inlet of the storage unit, the amount of water stored in the storage unit can be determined by the amount of water in the shut-off control tank. By setting the first inlet of the shut-off control tank to be on the same plane as the water storage warning line of the storage unit, when water begins to enter the shut-off control tank, it indicates that the amount of water in the storage unit has reached the water storage warning line. As the amount of water entering increases, the overall weight of the shut-off control tank increases. When the total weight of the shut-off control tank and the water inside exceeds the weight of the counterweight, the counterweight can be tilted up through the connector to prevent it from contacting the inlet control valve. The valve core of the inlet control valve then rebounds to close the inlet water path, thus shutting off the water supply to the filtration unit. When the water level in the storage unit is used down to below the warning line, the water level in the on / off control tank drops synchronously, causing the tank's weight to decrease. When the total weight of the on / off control tank and its contents is less than the weight of the counterweight, the counterweight, through a connector, tilts the on / off control tank upwards, causing the counterweight to descend and contact the inlet control valve. At this point, the inlet water path of the inlet control valve opens, and water re-enters the filtration unit for filtering. This device has a simple structure and relies on the principle of consistent water level in the connected water paths to automatically control whether the filtration unit filters water without consuming electricity. It offers high filtration reliability, low risk of machine failure, and is applicable to various water filtration machines, making it widely applicable. Attached Figure Description

[0049] First Embodiment

[0050] Please refer to Figure 1 Cooperate Figure 2 This embodiment provides a rocker-type cut-off water purification device 100, which includes a water flow cut-off unit, a water filtration unit 120 and a water storage unit 130 connected in sequence.

[0051] The water filtration unit 120 is an RO filter, and the water storage unit 130 is a water storage tank.

[0052] The water flow interruption unit includes an inlet control valve 111 and a control valve on / off assembly. The inlet control valve 111 is connected to the water filter unit 120 through a pipe. Therefore, water does not pass through the control valve on / off assembly during the process of flowing from the water flow interruption unit to the water filter unit 120. Instead, it flows directly from the inlet water passage of the inlet control valve 111 to the water filter unit 120.

[0053] The control valve on / off assembly includes a mounting base 1121, a counterweight 1122, an on / off control water tank 1123, and a connector 1124. The connector 1124 is rotatably connected to the mounting base 1121 and can rotate relative to the mounting base 1121. The rotation is centered on the fixed point between the connector 1124 and the mounting base 1121.

[0054] The counterweight 1122 and the on / off control water tank 1123 are both fixed to both sides of the mounting base 1121 by the connector 1124. Therefore, the counterweight 1122, the on / off control water tank 1123 and the connector 1124 form a seesaw structure. The position of the counterweight 1122 and the on / off control water tank 1123 is controlled according to the gravity difference between the two ends of the seesaw.

[0055] In this embodiment, the counterweight 1122 is located below the on / off control water tank 1123, and the weight of the counterweight 1122 is greater than the weight of the on / off control water tank 1123, but less than the weight of the on / off control water tank 1123 when it is full of water.

[0056] The counterweight 1122 is spaced apart from the inlet control valve 111 and can selectively contact the inlet control valve 111. It can be understood that the selective contact here means that since the counterweight 1122, the on / off control water tank 1123 and the connecting part 1124 form a seesaw structure, when the inlet control valve 111 is below the counterweight 1122 and the weight of the on / off control water tank 1123 is less than the weight of the counterweight 1122, the counterweight 1122 contacts the inlet control valve 111 to ensure that the water inlet path is unobstructed.

[0057] Specifically, since the counterweight 1122 is located below the on / off control water tank 1123, there is no water in the on / off control water tank 1123 during normal water filtration. When it is necessary to shut off the water supply, the water level in the storage unit 130 rises, causing the on / off control water tank 1123 to go from empty to filled with water, and the water level gradually increases. When the total weight of the on / off control water tank 1123 after being filled with water exceeds that of the counterweight 1122, the entire on / off control water tank 1123 moves downward, causing the water level in the on / off control water tank 1123 to rise relative to the storage unit 130. The water levels in water units 130 are inconsistent, and the water level in the on / off control water tank 1123 is low. In order to balance this water level difference, the water level in the water storage unit 130 will drop slightly to form a clean water storage buffer. During the process of the on / off control water tank 1123 moving downward, the counterweight 1122 moves upward and disengages from the valve core 1111 of the inlet control valve 111. The valve core 1111 moves towards the inlet water path under the rebound force of the valve core elastic element and cuts off the inlet water path, so as not to cause clean water to overflow from the water storage unit 130.

[0058] The first inlet 1125 of the on / off control water tank 1123 is connected to the inlet of the water storage unit 130, and when the counterweight 1122 is far away from the water inlet control valve 111, the first inlet 1125 of the on / off control water tank 1123 and the water storage warning line 131 of the water storage unit 130 are located on the same plane.

[0059] Since the first water inlet 1125 serves to form a communication channel with the water storage unit 130, the on / off control system connects the water tank 1123, the water storage unit 130, and the connecting pipes. The water level in the water storage unit 130 of the purified water filtered by the water filtration unit 120 can be determined by whether there is water in the water tank 1123 and the water level thereafter. To facilitate adjustment of the filtration progress of the water filtration unit 120, a water storage warning line 131 can be pre-set in the water storage unit 130. When the water level reaches the water storage warning line 131, it is necessary to prepare to cut off the water inlet of the water filtration unit 120 to prevent the water in the water storage unit 130 from overflowing due to excessive water storage.

[0060] In this embodiment, the on / off control water tank 1123 is an open tank, and for ease of installation, the top of the mounting base 1121 and the top of the water storage unit 130 are located on the same plane.

[0061] Please refer to Figure 4 In this embodiment, the water inlet control valve 111 includes a valve core 1111 and a valve body 1112, with the valve core 1111 disposed within the valve body 1112. A fixing member 1126 is provided on the counterweight 1122. When the counterweight 1122 contacts the water inlet control valve 111, the fixing member 1126 fixes the valve core 1111. In the above embodiment, the structure is designed so that the water inlet passage is unobstructed when the valve core 1111 of the water inlet control valve 111 is extended. Therefore, after the fixing member 1126 fixes the valve core 1111, the water inlet passage remains unobstructed.

[0062] The valve core 1111 of the solenoid valve includes a valve core 1111 housing, a valve core 1111 body housed within the valve core 1111 housing, and a valve core elastic element. The valve core elastic element is fixed to the side of the valve core 1111 body away from the valve body 1112. The valve core elastic element can apply elastic force to the valve core 1111 to ensure that the valve core 1111 can open and close the water inlet passage within the valve body 1112.

[0063] In this embodiment, the water inlet control valve 111 is a solenoid valve, and the fixing member 1126 is a magnetic member.

[0064] Furthermore, the inlet control valve 111 also includes a valve core elastic element, which is disposed within the valve body 1112 and fixed to the valve core 1111, and is located at one end of the valve core 1111 near the counterweight 1122. The valve core elastic element can push the valve core 1111 to move.

[0065] The valve core 1111 controls the opening and closing of the water inlet passage within the water inlet control valve 111. When the water inlet passage is open, the valve core 1111 is fixed by the fixing member 1126, causing the counterweight 1122 to contact the water inlet control valve 111. When water enters the on / off control tank 1123 and its weight exceeds that of the counterweight 1122, the counterweight 1122 rises and moves away from the water inlet control valve 111. The valve core 1111 then disengages from the fixing member 1126 and moves towards the water inlet passage, blocking it and effectively cutting off the water inlet passage. When the water level in the on / off control tank 1123 decreases and its weight is less than that of the counterweight 1122, the counterweight 1122 descends and moves towards the water inlet control valve 111. At this point, the valve core 1111 is fixed by the fixing member 1126, opening the water inlet passage and allowing water to enter.

[0066] In this embodiment, to prevent the counterweight 1122 or the water tank 1123 filled with water from becoming too heavy and shortening the lifespan of the connector 1124, the connector 1124 is a zigzag-shaped connector, with the midpoint of the zigzag line rotatably connected to the mounting base 1121. The zigzag-shaped connector 1124 allows the heavier end to receive an upward force when it sinks, parallel to the direction of the connector 1124, thus extending the service life of the connector 1124.

[0067] The present invention provides a rocker-type cut-off water purification device 100, the working principle of which is as follows:

[0068] Water filtration process: Please refer to Figure 2 The counterweight 1122 has a mass greater than the weight of the on / off control water tank 1123 itself. Therefore, the counterweight 1122 descends to magnetically engage with the fixing part 1126 on the water inlet control valve 111, and the water inlet path of the water inlet control valve 111 is opened. Water flows along the water inlet path of the water inlet control valve 111 into the water filter unit 120 for filtration. The filtered water flows from the water filter unit 120 to the water storage unit 130.

[0069] The process for determining when to stop filtration and its working principle: Please refer to... Figure 3 As purified water continues to flow into the water storage unit 130, the water level in the water storage unit 130 continues to rise. Since the on / off control water tank 1123 is connected to the water inlet of the water storage unit 130, the amount of water stored in the water storage unit 130 can be determined by the amount of water in the on / off control water tank 1123. By setting the first inlet 1125 of the on / off control water tank 1123 to be on the same plane as the water storage warning line 131 of the water storage unit 130, when water begins to enter the on / off control water tank 1123, it indicates that the water volume in the water storage unit 130 has reached the water storage warning line 131. As the amount of water entering increases, the overall weight of the on / off control water tank 1123 increases. When the total weight of the on / off control water tank 1123 and the water inside it exceeds the weight of the counterweight 1122, the counterweight 1122 can be lifted by the connector 1124 so that the counterweight 1122 does not contact the water inlet control valve 111. At this time, the actual water level line 132 in the water storage unit 130 exceeds the water storage warning line 131. The valve core 1111 of the inlet control valve 111 is released from the fixing action of the fixing member 1126 and moves towards the inlet water passage under the elastic force of the valve core elastic member, and closes the inlet water passage of the inlet control valve 111. The water source of the filter unit 120 is cut off. After the water in the filter unit 120 is completely filtered and flows into the water storage unit 130, the filter unit 120 stops filtering water.

[0070] The process and working principle for determining when to restore filtered water quality: Please refer to... Figure 2When the purified water in the water storage unit 130 is used, the water level in the water storage unit 130 drops, and similarly, the water level in the on / off control water tank 1123 also drops, reducing the weight of the on / off control water tank 1123. When the total weight of the on / off control water tank 1123 and the water inside is less than the weight of the counterweight 1122, the counterweight 1122 tilts the on / off control water tank 1123 up via the connector 1124, causing the counterweight 1122 to drop down and come into contact with the inlet control valve 111. The valve core 1111 of the inlet control valve 111 is magnetically fixed by the fixing member 1126 and moved away from the inlet water path. At this time, the inlet water path of the inlet control valve 111 opens, and water enters the water filtration unit 120 for filtration again through the inlet control valve 111. This cycle repeats, achieving automated water purification and avoiding the situation where purified water cannot be consumed and overflows due to prolonged filtration.

[0071] Because the device of the present invention can achieve automated control of the water filtration process without electricity, the device has a simple structure, high water filtration reliability, low risk of machine failure, and can be applied to a variety of water filtration machines, it has a wide range of applications.

[0072] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
