Abstract
Description
Technical Field
[0001] The utility model relates to an adaptive water inlet control device. Background Art
[0002] Currently, in common drinking fountains and water purifier systems, in order to more accurately control the water inlet and avoid the occurrence of water shortage or excessive water inlet in the system, various water level sensors are often separately set to monitor the water level and solenoid valves are used to switch on and off the water inlet waterway. According to the data transmitted back by the water level sensor, the solenoid valve is controlled to switch on and off through a program to achieve the control of the water inlet. However, setting the water level sensor and the solenoid valve means that circuits need to be laid in the system. Since the waterway system has very strict safety requirements for the circuits, in order to meet the circuit safety requirements, the structure in the system will become very complex, causing many obstacles and difficulties for product design. In addition, setting the water level sensor and the solenoid valve will also lead to a substantial increase in cost.
[0003] Therefore, how to overcome the above-mentioned existing defects has become an important issue that needs to be solved urgently by those skilled in the art. Summary of the Utility Model
[0004] The utility model overcomes the above technical deficiencies and provides an adaptive water inlet control device.
[0005] To achieve the above object, the utility model adopts the following technical solutions:
[0006] An adaptive water inlet control device includes a magnetically controlled water inlet valve 1 without electric drive. An inlet 11 for connecting the water inlet pipeline is provided on the magnetically controlled water inlet valve 1. The magnetically controlled water inlet valve 1 controls the opening and closing of the valve itself according to the strength / weakness of the magnetic force. The magnetically controlled water inlet valve 1 is connected to a water outlet valve 3 through a waterway. An outlet 31 for docking and communicating with the bottom of an external water storage container is provided on the water outlet valve 3. The outlet 31 is opened when it is docked with the water storage container in place and is normally closed at other times. The inner cavity of the water outlet valve 3 is connected to a magnetically controlled component 4 without electric drive through a pipeline 34. The magnetically controlled component 4 controls whether to apply a strong magnetic force to the magnetically controlled water inlet valve 1 according to the high / low water pressure.
[0007] Preferably, the magnetically controlled component 4 is attached to the outer wall surface of the magnetically controlled water inlet valve 1.
[0008] Preferably, the magnetically controlled component 4 includes a sealing cover 44 connected to the pipeline 34. A rolling diaphragm 41 is fixed on the sealing cover 44. The rolling diaphragm 41 is located between the sealing cover 44 and the magnetically controlled water inlet valve 1. The opening of the rolling diaphragm 41 is attached and sealed to the sealing cover 44 to form a sealing cavity 413 communicating with the pipeline 34. A magnet 42 is fixed on the outer surface of the end of the rolling diaphragm 41 away from the sealing cover 44. The rolling diaphragm 41 deforms according to the magnitude of the water pressure borne by the sealing cavity 413 to drive the magnet 42 to approach / away from the magnetically controlled water inlet valve 1.
[0009] Preferably, a guiding post 12 protrudes from the outer surface of the magnetically controlled water inlet valve 1. Both the rolling diaphragm 41 and the magnet 42 are sleeved on the guiding post 12.
[0010] Preferably, a guiding groove 412 for sleeving on the guiding post 12 is concavely provided on the end surface of the rolling diaphragm 41 close to the magnetically controlled water inlet valve 1.
[0011] Preferably, a first return spring 43 is provided between the rolling diaphragm 41 and the magnetically controlled water inlet valve 1. The first return spring 43 is used to push the end of the rolling diaphragm 41 close to the magnetically controlled water inlet valve 1 away from the magnetically controlled water inlet valve 1; or a first return spring 43 is provided between the magnet 42 and the magnetically controlled water inlet valve 1. The first return spring 43 is used to push the magnet 42 away from the magnetically controlled water inlet valve 1.
[0012] Preferably, a wavy fold is provided on the side wall surface of the rolling diaphragm 41.
[0013] Preferably, a valve core 32 and a second return spring 33 are provided in the water outlet valve 3. The valve core 32 is inserted through the water outlet 31. The second return spring 33 is used to drive the valve core 32 to move outward and reset to block the water outlet 31. The valve core 32 is pushed inward and opened and does not block the water outlet 31 after the water outlet 31 is docked with the water storage container in place.
[0014] Compared with the prior art, the beneficial effects of the present utility model are:
[0015] The adaptive water inlet control device in this case controls whether water enters through the opening and closing of a magnetically controlled water inlet valve. The magnetically controlled water inlet valve does not require electricity to operate. The opening and closing of the magnetically controlled water inlet valve is controlled by a magnetic control component, which also does not require electricity to operate. The magnetically controlled water inlet valve will close when affected by a strong magnetic force. Conversely, if it is not affected by a magnetic force or only affected by a weak magnetic force, it will open. The magnetic control component is connected to the water outlet valve through a pipeline and incorporated into the water circuit. When the water pressure in the water circuit is high, that is, when there is no water storage container connected to the water outlet and the magnetic control component directly bears the water inlet pressure, and when there is a water storage container connected to the water outlet and the water level in the water storage container has reached the specified height, and the magnetic control component is connected to the water storage container and bears the water pressure at the deepest level, the magnetic control component will apply a strong magnetic force to the magnetically controlled water inlet valve to control it to close. At other times, the magnetic control component will not apply a strong magnetic force to the magnetically controlled water inlet valve, and the magnetically controlled water inlet valve will remain open. When the water storage container is properly connected to the water outlet and the magnetically controlled water inlet valve is open, the water in the water inlet pipeline can flow into the water storage container. In this way, through the cooperation of the magnetically controlled water inlet valve, the water outlet valve, and the magnetic control component, the adaptive water inlet control device in this case can adaptively complete water inlet control without using a water level sensor and a solenoid valve and without electricity, which can greatly reduce the complexity of the water inlet control structure and also significantly reduce the manufacturing cost.

[0021] The features of the present utility model and other related features are further described in detail below through embodiments for the understanding of those skilled in the same industry:
[0022] As Figures 1 to 5As shown in the figure, an adaptive water inlet control device includes a magnetically controlled water inlet valve 1 driven without electricity. The magnetically controlled water inlet valve 1 is provided with a water inlet 11 for connecting to a water inlet pipeline. The magnetically controlled water inlet valve 1 controls the opening and closing of the valve itself according to the strength / weakness of the magnetic force. The magnetically controlled water inlet valve 1 is connected to a water outlet valve 3 through a waterway. The water outlet valve 3 is provided with a water outlet 31 for docking and communicating with the bottom of an external water storage container. The water outlet 31 is opened when it is docked with the water storage container in place and is normally closed at other times. The inner cavity of the water outlet valve 3 is connected to a magnetically controlled component 4 driven without electricity through a pipeline 34. The magnetically controlled component 4 controls whether to apply a strong magnetic force to the magnetically controlled water inlet valve 1 according to the high / low water pressure.
[0023] As described above, the adaptive water inlet control device in this case controls whether to let water in through the opening and closing of the magnetically controlled water inlet valve 1. The magnetically controlled water inlet valve 1 does not need to be powered on for use. The opening and closing of the magnetically controlled water inlet valve 1 are controlled by the magnetically controlled component 4, and the magnetically controlled component 4 also does not need to be powered on for use. The magnetically controlled water inlet valve 1 will close when affected by a strong magnetic force. Conversely, if it is not affected by a magnetic force or only affected by a weak magnetic force, it will open. The magnetically controlled component 4 is connected to the water outlet valve 3 through the pipeline 34 and is connected to the waterway. When the water pressure in the waterway is relatively high, that is, when there is no water storage container docked on the water outlet 31 and the magnetically controlled component 4 directly bears the water inlet pressure, and when there is a water storage container docked on the water outlet 31 and the water level in the water storage container has reached the specified height, the magnetically controlled component 4 is connected to the water storage container and bears the water pressure at the deepest level, the magnetically controlled component 4 will apply a strong magnetic force to the magnetically controlled water inlet valve 1 to control the magnetically controlled water inlet valve 1 to close. At other times, the magnetically controlled component 4 will not apply a strong magnetic force to the magnetically controlled water inlet valve 1, and the magnetically controlled water inlet valve 1 will remain open. When the water storage container is docked in place with the water outlet 31 and the magnetically controlled water inlet valve 1 is open, the water in the water inlet pipeline can flow into the water storage container. In this way, through the cooperation of the magnetically controlled water inlet valve 1, the water outlet valve 3 and the magnetically controlled component 4, the adaptive water inlet control device in this case can complete the water inlet control adaptively without using a water level sensor and a solenoid valve and without electricity, which can greatly reduce the complexity of the water inlet control structure and also significantly reduce the manufacturing cost.
[0024] Specifically, the on-off structure of the magnetically controlled water inlet valve 1 is the same as that of a conventional solenoid valve. The difference between the two is that the magnetically controlled water inlet valve 1 is not powered on and does not have an electromagnetic coil for generating magnetic force by itself.
[0025] As Figure 2 shown, preferably, the magnetically controlled component 4 is attached to the outer wall surface of the magnetically controlled water inlet valve 1. In this way, it can be ensured that the distance between the magnetically controlled water inlet valve 1 and the magnetically controlled component 4 is relatively close, ensuring that the magnetically controlled water inlet valve 1 can effectively respond to the magnetic force applied by the magnetically controlled component 4 to achieve opening and closing.
[0026] As Figure 3 、Figure 5 As shown, preferably, the magnetically controlled component 4 includes a sealing cover 44 connected to the pipeline 34. A rolling diaphragm 41 is fixed on the sealing cover 44. The rolling diaphragm 41 is located between the sealing cover 44 and the magnetically controlled water inlet valve 1. An opening of the rolling diaphragm 41 is attached to and sealed with the sealing cover 44 to form a sealed cavity 413 communicating with the pipeline 34. A magnet 42 is fixed on the outer surface of the end of the rolling diaphragm 41 away from the sealing cover 44. The rolling diaphragm 41 deforms according to the magnitude of the water pressure borne by the sealed cavity 413 to drive the magnet 42 to approach / away from the magnetically controlled water inlet valve 1.
[0027] As described above, the magnetically controlled component 4 of this case includes a rolling diaphragm 41, a sealing cover 44, and a sealed cavity 413 formed therebetween and communicating with the inner cavity of the water outlet valve 3. When the external water storage container is docked with the water outlet 31 in place, a communicating vessel is formed between the water storage container and the rolling diaphragm 41. Since the water outlet 31 is docked with the bottom of the water storage container, when the water level in the water storage container rises, the water pressure borne inside the rolling diaphragm 41 will also increase. Under the action of the water pressure, the rolling diaphragm 41 will gradually unfold. Driven by the unfolding and deformation of the rolling diaphragm 41, the magnet 42 will also approach the magnetically controlled water inlet valve 1. When the water level in the water storage container reaches the specified height, the corresponding rolling diaphragm 41 will also unfold to a certain extent, making the magnet 42 close to the magnetically controlled water inlet valve 1. In this way, the magnetically controlled water inlet valve 1 will close under the influence of the magnetic force of the magnet 42, and the water inlet will stop. Additionally, when there is no water storage container docked on the water outlet 31, the water outlet 31 is closed, and the water entering from the water inlet 11 will directly enter the sealed cavity 413, which will also increase the water pressure borne by the sealed cavity 413, prompting the rolling diaphragm 41 to unfold and making the magnet 42 close to the magnetically controlled water inlet valve 1 to close it and stop the water inlet. Conversely, when there is a water storage container docked on the water outlet 31, but the water level in the water storage container does not reach the specified water level height, due to the relatively small water pressure borne by the rolling diaphragm 41, the rolling diaphragm 41 is difficult to fully unfold in place, so that the magnet 42 cannot close to the magnetically controlled water inlet valve 1, and the magnetically controlled water inlet valve 1 will not close, and water can continue to flow into the water storage container. Thus, the magnetically controlled component 4 of this case can adaptively control the opening and closing of the magnetically controlled water inlet valve 1 based on whether there is a water storage container docked on the water outlet 31 and the water level height of the water storage container without electric drive through the rolling diaphragm 41 and the magnet 42.
[0028] Specifically, when the magnet 42 is attached to the magnetically controlled water inlet valve 1, it exerts a strong magnetic force on it.
[0029] As Figure 3 、 Figure 5As shown, preferably, a guiding post 12 protrudes from the outer surface of the magnetically controlled water inlet valve 1, and both the rolling diaphragm 41 and the magnet 42 are sleeved on the guiding post 12. In this way, when the rolling diaphragm 41 expands and contracts, the magnet 42 can be ensured to be accurately aligned with the magnetically controlled water inlet valve 1, so as to achieve precise control and avoid affecting the magnitude of the magnetic force applied to the magnetically controlled water inlet valve 1 due to the offset of the magnet 42.
[0030] As Figure 3 , Figure 5 shown, preferably, a guiding groove 412 for sleeving on the guiding post 12 is concavely provided on the end surface of the rolling diaphragm 41 close to the magnetically controlled water inlet valve 1. In this way, the rolling diaphragm 41 can be sleeved on the guiding post 12 through the guiding groove 412.
[0031] As Figure 3 , Figure 5 shown, preferably, a first return spring 43 is provided between the rolling diaphragm 41 and the magnetically controlled water inlet valve 1, and the first return spring April 1, 2023 43 is used to push the end of the rolling diaphragm 41 close to the magnetically controlled water inlet valve 1 away from the magnetically controlled water inlet valve 1; or a first return spring 43 is provided between the magnet 42 and the magnetically controlled water inlet valve 1, and the first return spring 43 is used to push the magnet 42 away from the magnetically controlled water inlet valve 1.
[0032] As described above, by providing the first return spring 43 between the rolling diaphragm 41 and the magnetically controlled water inlet valve 1 or between the magnet 42 and the magnetically controlled water inlet valve 1, it can be effectively ensured that when the rolling diaphragm 41 does not bear a large water pressure, the magnet 42 can be away from the magnetically controlled water inlet valve 1 under the elastic force of the first return spring 43, so as to ensure the smooth opening of the magnetically controlled water inlet valve 1. In addition, due to the provision of the first return spring 43, when the rolling diaphragm 41 unfolds, it is necessary to overcome the elastic force of the first return spring 43 synchronously. In this way, by adjusting the elastic coefficient of the first return spring 43, the magnitude of the water pressure inside the rolling diaphragm 41 when the magnet 42 approaches the magnetically controlled water inlet valve 1 can be accurately controlled, and then the water level height at which the magnetically controlled water inlet valve 1 closes can be accurately controlled.
[0033] Specifically, the first return spring 43 is also sleeved on the guiding post 12.
[0034] As Figure 3 , Figure 5 shown, preferably, a wavy fold is provided on the side wall surface of the rolling diaphragm 41. In this way, when the water pressure borne by the rolling diaphragm 41 changes, the rolling diaphragm 41 can be better deformed through the unfolding and folding of the wavy fold, so as to drive the displacement of the magnet 42.
[0035] As Figure 2 , Figure 4As shown, preferably, a valve core 32 and a second reset spring 33 are provided in the water outlet valve 3, and the valve core 32 is arranged in the water outlet 31. The second reset spring 33 is used to drive the valve core 32 to move outward to reset and block the water outlet 31. After the water outlet 31 is docked with the water storage container, the valve core 32 is pushed inward without blocking the water outlet 31.
[0036] As described above, when the water outlet valve 3 is not connected to the water outlet 31, the valve core 32 is driven back by the second return spring 33 to block the water outlet 31, preventing water from flowing out of the water outlet valve 3. Only when the water outlet 31 is properly connected to the water outlet 31 will the water outlet overcome the elastic force of the second return spring 33 and push the valve core 32 open, allowing water to flow into the water outlet 31 through the water outlet 31.
[0037] As mentioned above, this case protects an adaptive water inlet control device, and all technical solutions that are identical or similar to this case should be deemed to fall within the scope of protection of this case.
