Description

Technical Field

[0001] This invention relates to the field of water storage and extraction technology, and more particularly to a water storage and extraction device. Background Technology

[0002] Water storage and retrieval devices typically include a base and a water tank that can be detachably placed on the base. After the water tank is placed on the base, the water supply pipeline fills the water tank with water as needed. Existing water storage and retrieval devices are usually also equipped with a liquid level detection and control device to detect the liquid level in the water tank and control the filling of water into the water tank.

[0003] However, existing liquid level detection and control devices are limited by their working principle and need to be installed on the water tank, for example, in the inner cavity of the water tank or on the outer wall of the water tank. This results in problems such as complex water tank structure, high processing and installation difficulty, and inconvenience in cleaning. Summary of the Invention

[0004] To address the aforementioned technical problems in the prior art, embodiments of the present invention provide a water storage and extraction device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of the present invention is as follows:

[0006] A water storage and retrieval device includes: a base and a water tank detachably placed on the base. After the water tank is placed on the base, a water injection channel is formed between the base and the water tank. A water supply pipeline injects water into the water tank through the water injection channel. A switch valve for controlling the on / off state of the water supply pipeline is provided on the water supply pipeline. The water storage and retrieval device also includes a fluid control valve disposed in the base.

[0007] The fluid control valve includes: a valve core mechanism, a triggering mechanism, and a controlled mechanism;

[0008] The valve core mechanism includes:

[0009] The valve body contains an active valve chamber.

[0010] An active valve core is disposed in the active valve chamber and is movable along the active valve chamber, such that the active valve core has a first position and a second position located at both ends of the moving stroke;

[0011] A magnet component for applying a magnetic force to the active valve core;

[0012] A force-applying component, disposed in the valve body, for applying force to the active valve core;

[0013] The triggering mechanism includes: a pressure acquisition port, a flexible membrane disposed at the pressure acquisition port, and a contact connected to the active valve core and driven by the flexible membrane through contact with the flexible membrane. The pressure acquisition port is connected to the water tank through the water injection channel to collect the pressure of the water in the water tank.

[0014] The controlled mechanism responds to the action of the active valve core by sending a control signal to at least control the on / off state of the switching valve; wherein:

[0015] After the active valve core switches to the first position, the magnetic force exerted by the magnet component on the active valve core constitutes a first magnetic holding force for holding the active valve core in the first position; after the active valve core switches to the second position, the magnetic force exerted by the magnet component on the active valve core constitutes a second magnetic holding force for holding the active valve core in the second position.

[0016] The direction of the pressure exerted by the water at the pressure acquisition port on the flexible membrane is opposite to the direction of the force exerted by the force-applying component on the active valve core.

[0017] Preferably,

[0018] The magnet component includes an active magnet and a positioning magnet. The active magnet is disposed in the active valve core, and the positioning magnet is disposed in the valve body and adjacent to the active magnet.

[0020] Preferably, the fluid control valve further includes a bias magnet;

[0021] The magnetic forces between the active magnet, the positioning magnet, and the bias magnet constitute a first magnetic holding force for holding the active valve core in a first position and a second magnetic holding force for holding the active valve core in a second position. The bias magnet causes the first magnetic holding force to be greater than or less than the second magnetic holding force.

[0022] Preferably, the bias magnet is configured to be position-adjustable for adjusting the magnitude of the first magnetic holding force and / or the second magnetic holding force.

[0023] Preferably, the first magnetic holding force and / or the second magnetic holding force are adjusted by selectively replacing bias magnets with different magnetic induction intensities.

[0028] A passive magnet is disposed in the passive valve core;

[0029] A controlled port is disposed at the axial end of the passive valve chamber, and the controlled port is connected to a fluid line downstream of the switching valve; wherein:

[0030] The passive valve core is driven by the active valve core through the magnetic force between the passive magnet and the active magnet, so that when the active valve core switches between the first position and the second position, the passive valve core moves along the passive valve cavity to control the opening and closing of the controlled port.

[0031] The switching valve is a diaphragm valve, and the accumulator port of the diaphragm valve is connected to the controlled port. When the controlled port is open, the accumulator port releases pressure and opens the diaphragm valve. When the controlled port is closed, the accumulator port stores pressure and closes the diaphragm valve.

[0032] Preferably, the passive valve chamber includes multiple passive valve chambers, each of which is provided with a passive valve core for controlling the opening and closing of the corresponding controlled port. The opening and closing of the diaphragm valve is controlled by controlling the opening and closing of the controlled port of one of the passive valve chambers, and the controlled equipment is controlled by controlling the opening and closing of the controlled ports corresponding to the remaining passive valve chambers.

[0033] Preferably, the controlled mechanism is an electromagnetic controlled mechanism, which is an electromagnetic sensor, and the electromagnetic sensor sends an electrical signal in response to the change in magnetic field caused by the change in the position of the active valve core.

[0034] Preferably, a docking valve is provided between the water tank and the base; the docking valve includes a first docking mechanism disposed on the platform of the base and a second docking mechanism disposed on the bottom of the water tank. After the water tank is docked to the base, the first docking mechanism and the second docking mechanism cooperate to form the water injection channel.

[0035] Preferably, the water injection channel is opened after the water tank is connected to the base and twisted.

[0036] Preferably, the force-applying component is a spring.

[0037] Compared with the prior art, the beneficial effects of the water storage and extraction device disclosed in this invention are:

[0038] 1. The present invention utilizes a fluid control valve installed on a base to collect the pressure of water in a water tank and controls the opening and closing of a switch valve based on the collected pressure, thereby controlling the injection of water into the water tank. This avoids the need to install relevant liquid level detection and control devices on the water tank and control the injection of water into the water tank based on the detected liquid level.

[0056] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0057] like Figure 2A and Figure 2B As shown, this invention discloses a water storage and retrieval device, which includes: a base 200, a water tank 100, a water supply pipeline 500, a switching valve 400, a docking valve 600, and a fluid control valve 300. The water tank 100 is detachably placed on the base 200, and the water supply pipeline 500 is connected to the water supply port at the upper part of the base 200. The docking valve 600 includes a first docking mechanism 601 and a second docking mechanism 602. The first docking mechanism 601 is installed at the water supply port of the base 200, and the second docking mechanism 602 is installed at the water inlet at the bottom of the water tank 100. When the water tank 100 is separated from the base 200, the first docking mechanism 601 closes the water supply port of the base 200, thereby... To prevent water supplied by the water supply pipe 500 from overflowing, the second docking mechanism 602 closes the water inlet at the bottom of the water tank 100, thereby preventing water in the water tank 100 from leaking through the water inlet. After the water tank 100 is placed on the base 200 and docking is completed, the first docking mechanism 601 and the second docking mechanism 602 are opened, so that a water injection channel 610 is formed between the water tank 100 and the base 200, and the water supply pipe 500 can inject water into the water tank 100 through the water injection channel 610.

[0058] The switch valve 400 is installed on the water supply pipeline 500 and is located in or outside the base 200. The switch valve 400 is used to directly control the opening and closing of the water supply pipeline 500. After the switch valve 400 opens the water supply pipeline 500, the water supply pipeline 500 fills the water tank 100 with water. After the switch valve 400 closes the water supply pipeline 500, the water supply pipeline 500 stops filling the water tank 100 with water.

[0059] In this invention, the fluid control valve 300 is mounted on the base 200 rather than the water tank 100. This invention aims to use the fluid control valve 300 mounted on the base 200 to collect the pressure of the water in the water tank 100 and control the opening and closing of the switch valve 400 based on the collected pressure, thereby controlling the on / off state of the water supply pipeline 500. This invention further aims to control the liquid level difference of a single water injection, the liquid level height when water injection stops (upper liquid level height), and the liquid level height when water injection starts (lower liquid level height) by setting an action threshold for the fluid control valve 300. This invention further aims to adjust the liquid level difference of a single water injection, the liquid level height when water injection stops, and the liquid level height when water injection starts by setting the action threshold of the fluid control valve 300 to be adjustable.

[0060] like Figure 2A and Figure 2B As shown, the fluid control valve 300 includes: a valve core mechanism 10, a triggering mechanism 20, and a controlled mechanism.

[0061] The valve core mechanism 10 includes a valve body 11, an active valve core 121, a magnet component, and a force-applying component 30. The valve body 11 has a linearly extending active valve chamber 111. The active valve core 121 is disposed within the active valve chamber 111 and is capable of linear movement along the active valve chamber 111, thus having a first position and a second position located at both ends of its displacement stroke. The force-applying component 30 is disposed in the valve body 11 for applying force to the active valve core 121.

[0062] The triggering mechanism 20 includes: a pressure acquisition port 21, a flexible diaphragm 22 disposed at the pressure acquisition port 21, and a contact 23 connected to the active valve core 121 and driven by the flexible diaphragm 22 through contact with it. The pressure acquisition port 21 is connected to the water tank 100 through the water injection channel 610 to collect the pressure of the water at the bottom of the water tank 100. Thus, the water acts on the flexible diaphragm 22 and exerts force on the contact 23 through the flexible diaphragm 22, thereby exerting force on the active valve core 121. The force exerted by the water on the active valve core 121 is opposite to the force exerted by the force-applying component 30 on the active valve core 121.

[0063] The controlled mechanism is used to send a control signal to the switching valve in response to the action of the active valve core 121 to control the opening and closing of the switching valve 400. Specifically, when the active valve core 121 switches from the first position to the second position, the controlled mechanism controls the switching valve 400 to close. After the switching valve 400 is closed, the water supply pipeline 500 stops injecting water into the water tank 100. When the active valve core 121 switches from the second position to the first position, the controlled mechanism controls the switching valve 400 to open. After the switching valve 400 is opened, the water supply pipeline 500 starts injecting water into the water tank 100.

[0064] For ease of explanation of the fluid control valve 300, it can be assumed that the first position of the active valve core 121 is aligned with the direction of the force applied by the force-applying component 30 to the active valve core 121, and thus, the second position of the active valve core 121 is aligned with the direction of the force applied by the water to the active valve core 121. Figure 1A , Figure 1B Taking the disclosed structure as an example, the force exerted by water on the active valve core 121 is downward, while the force exerted by the force-applying component 30 on the active valve core 121 is upward. Therefore, as... Figure 1A As shown, the high position of the active valve core 121 is the first position of the active valve core 121, as... Figure 1B As shown, the lower position of the active valve core 121 is the second position of the active valve core 121.

[0065] A magnetic component is disposed in the valve body 11 to apply a magnetic force to the active valve core 121. Specifically, after the active valve core 121 is switched to the first position, the magnetic force exerted by the magnetic component on the active valve core 121 constitutes a first magnetic holding force for holding the active valve core 121 in the first position; after the active valve core 121 is switched to the second position, the magnetic force exerted by the magnetic component on the active valve core 121 constitutes a second magnetic holding force for holding the active valve core 121 in the second position.

[0066] In this invention, the first magnetic holding force and the second magnetic holding force should be understood as:

[0067] The first magnetic holding force is a magnetic force used to prevent the active valve core 121 from switching from the first position to the second position. Accordingly, the magnitude of the first magnetic holding force should be equal to the force that drives the active valve core 121 to switch from the first position to the second position. The direction of the first magnetic holding force is opposite to the direction of movement of the active valve core 121. The second magnetic holding force is a magnetic force used to prevent the active valve core 121 from switching from the second position to the first position. Accordingly, the magnitude of the second magnetic holding force should be equal to the force that drives the active valve core 121 to switch from the second position to the first position. The direction of the second magnetic holding force is opposite to the direction of movement of the active valve core 121.

[0068] Since the direction of the force exerted by the water on the active valve core 121 is towards the second position, and is opposite to the direction of the first magnetic holding force and the same as the direction of the second magnetic holding force, and the direction of the force exerted by the force-applying component 30 on the active valve core 121 is towards the first position, and is the same as the direction of the first magnetic holding force and the opposite to the direction of the second magnetic holding force, and the direction of the force exerted by the water on the active valve core 121 is opposite to the direction of the force exerted by the force-applying component 30 on the active valve core 121, the mechanical inequality that causes the active valve core 121 to switch between the first position and the second position is as follows.

[0069] The mechanical inequality that causes the active valve core 121 to switch from the first position to the second position is:

[0070] F 流体 =P 流体 S>F 施力部件 +F 磁1

[0071] The mechanical inequality that causes the active valve core 121 to switch from the second position to the first position is:

[0072] F 流体 =P 流体 S < F 施力部件 -F 磁2

[0073] in:

[0074] F 施力部件 F is the force applied by the force-applying component 30 to the active valve core 121. 施力部件 F is a constant; 磁1 For the first magnetic holding force, F 磁2 For the second magnetic holding force, F 磁1 F 磁2 F is a constant; 流体 P is the force exerted by the water at the bottom of the water tank 100 on the active valve core 121. 流体 S is the water pressure (or intensity), S is the projected area of ​​water acting on the flexible membrane 22 in the direction of movement of the active valve core 121, S is a constant, and P is a constant. 流体 As a variable, therefore, F 流体 F is a variable. 流体 With P 流体 They exhibit a linear proportional relationship.

[0075] When F 流体 Increased and greater than F 施力部件 With F 磁1 When F is in the same position, the active valve core 121 will switch from the first position to the second position; and when F 流体 Decrease and less than F 施力部件 With F 磁2 When the difference is reached, the active valve core 121 will switch from the second position to the first position, thus obtaining the following balance equation:

[0076] The mechanical equilibrium equation that causes the active valve core 121 to switch from the first position to the second position is:

[0077] F 流体1 =P 流体1 S = F 施力部件 +F 磁1

[0078] The mechanical equilibrium equation that causes the active valve core 121 to switch from the second position to the first position is:

[0079] F 流体2 =P流体2 S = F 施力部件 -F 磁2

[0080] Combining the two equilibrium equations above, we can derive:

[0081] F 流体1 -F 流体2 =(P 流体1 -P 流体2 S = F 磁1 +F 磁2

[0082] in:

[0083] F 流体1 To enable the active valve core 121 to switch from the first position to the second position, the force application node of the water at the bottom of the water tank 100, F 流体2 To enable the active valve core 121 to switch from the second position to the first position, the water at the bottom of the water tank 100 applies force to the water. 流体1 To allow the active valve core 121 to switch from the first position to the second position, the water pressure node at the bottom of the water tank 100, P 流体2 The water pressure node at the bottom of the water tank 100 is used to switch the active valve core 121 from the second position to the first position.

[0084] From the above inequalities and equilibrium equations, it can be seen that:

[0085] 1. P 流体1 To switch the active valve core 121 to the second position of the water pressure node, this pressure node P 流体1 Depends on F 施力部件 With F 磁1 The sum of, therefore, while maintaining F 施力部件 Under the premise of constant, by increasing F 磁1 It can increase P 流体1 The value of , accordingly, is obtained by decreasing F. 磁1 It can reduce P 流体1 The value of P. Because after the active valve core 121 switches to the second position, the switch valve 400 closes and the water supply pipeline 500 closes, therefore, P 流体1 This is also the node pressure that causes water supply line 500 to stop filling water tank 100, P 流体1 This determines the height of the upper liquid level in water tank 100, thus, F 磁1 The height of the upper liquid level is determined by increasing F. 磁1 The height of the upper liquid level can be increased by reducing F. 磁1 This can lower the height of the upper liquid level. 流体2 To enable the active valve core 121 to switch to the first position of the water pressure node, this pressure node P 流体2 Depends on F施力部件 With F 磁2 The difference, therefore, in order to ensure F 施力部件 Under the premise of constant, by increasing F 磁2 It can reduce P 流体2 The value of F is determined by decreasing F. 磁2 It can increase P 流体2 The value of P. Because after the active valve core 121 switches to the first position, the switch valve 400 opens and the water supply pipeline 500 opens, therefore, P 流体2 This is also the node pressure at which the water supply line 500 begins to fill the water tank 100, P. 流体2 This determines the height of the lower liquid level in water tank 100, thus, F 磁2 The height of the liquid level is determined by increasing F. 磁2 The height of the lower liquid level can be reduced by decreasing F. 磁2 This can increase the height of the lower liquid level.

[0086] 2. P 流体1 -P 流体2 The pressure change range node for the active valve core 121 to switch between the first and second positions is also the pressure change range node for the water supply pipeline 500 to stop supplying water to the water tank 100 and start supplying water to the water tank 100. This pressure change range node characterizes the action threshold of the fluid control valve 300 of the present invention, and also characterizes the liquid level height difference of a single water injection in the water supply pipeline 500. As can be seen from the above equation, this pressure change range node depends on the first magnetic holding force F. 磁1 With the second magnetic holding force F 磁2 The sum, by adjusting F 磁1 With F 磁2 The sum of these can be used to adjust the liquid level difference in a single injection.

[0087] In some embodiments, the magnet component includes only an active magnet 131 and a passive magnet 133, and the first magnetic holding force and the second magnetic holding force are formed by the magnetic force between the active magnet 131 and the positioning magnet 132 (this case is not shown in the figures).

[0088] In some embodiments, such as Figure 1A and Figure 1B As shown, in addition to the active magnet 131 and the positioning magnet 132, the magnet component also includes a bias magnet 134. The first magnetic holding force and the second magnetic holding force are formed by the magnetic forces between the active magnet 131, the positioning magnet 132 and the bias magnet 134.

[0089] In some embodiments, the active magnet 131 and the positioning magnet 132 in the magnet component can both be magnets, or one of them can be a magnet and the other can be an iron component that can form a magnetic force with the magnet.

[0090] This invention discloses the following arrangements of magnet components.

[0091] The first arrangement of the magnet components:

[0092] like Figure 1A and Figure 1B As shown, the magnet component includes an active magnet 131, a positioning magnet 132, and a bias magnet 134.

[0093] An active magnet 131 is disposed on an active valve core 121, and a positioning magnet 132 is disposed on a valve body 11. The magnetic pole direction of the active magnet 131 is consistent with the moving direction of the active valve core 121. The active magnet 131 is arranged around the positioning magnet 132, and the magnetic pole direction of the active magnet 131 is the same as that of the positioning magnet 132. The opposite magnetic poles of the active magnet 131 and the positioning magnet 132 are oriented in the same direction. The positioning magnet 132 is formed by stacking two magnet units in the length direction. The active magnet 131 includes one magnet unit, and the length of the active magnet 131 is half the length of the positioning magnet 132.

[0094] The bias magnet 134 is disposed on the valve body 11 and located on one side of the second position of the active valve core 121 in the axial direction and opposite to the active magnet 131. Furthermore, the bias magnet 134 is opposite to the opposite magnetic pole of the active magnet 131.

[0095] like Figure 1B As shown, after the active valve core 121 switches to the second position, the active magnet 131 approaches the bias magnet 134 and forms a magnetic attraction between them, as... Figure 1A As shown, after the active valve core 121 switches to the first position, the active magnet 131 moves away from the bias magnet 134 and the magnetic attraction almost disappears. Therefore, the bias magnet 134 makes the force that drives the active valve core 121 to switch from the first position to the second position to overcome the first magnetic holding force less than the force that drives the active valve core 121 to switch from the second position to the first position to overcome the second magnetic holding force. Therefore, the magnet components arranged in this way make the first magnetic holding force less than the second magnetic holding force.

[0096] If the bias magnet 134 and the active magnet 131 are aligned with the same magnetic poles, after the active valve core 121 switches to the second position, the active magnet 131 approaches the bias magnet 134 and forms a magnetic repulsion force between them. After the active valve core 121 switches to the first position, the active magnet 131 moves away from the bias magnet 134 and the magnetic repulsion force almost disappears. Therefore, the bias magnet 134 makes the force that drives the active valve core 121 from the first position to the second position to overcome the first magnetic holding force greater than the force that drives the active valve core 121 from the second position to the first position to overcome the second magnetic holding force. Thus, the magnetic components arranged in this way make the first magnetic holding force greater than the second magnetic holding force.

[0097] It should be noted that:

[0098] In this invention, "opposite magnetic poles facing the same direction" means that the magnetic poles of different polarities of two magnets face the same direction. For example, if the N pole of one magnet faces upward (downward) and the S pole of the other magnet also faces upward (downward), then the opposite magnetic poles of the two magnets are said to face the same direction. Correspondingly, if the N pole of one magnet faces upward and the N pole of the other magnet also faces upward, then the like magnetic poles of the two magnets are said to face the same direction.

[0099] Magnetic pole direction refers to the indicated direction of the N and S poles of a magnet. For example, for a magnet with the N pole pointing upwards (downwards) and the S pole pointing downwards (upwards), the magnetic pole direction is vertical. Conversely, for a magnet with the N pole pointing to the left (right) and the S pole pointing to the right (left), the magnetic pole direction is horizontal. Generally, two magnets with the same magnetic pole direction can be understood as being parallel; two magnets with perpendicular magnetic pole directions can be understood as being perpendicular; the length of a magnet can be understood as its dimension along the magnetic pole direction, and the thickness of a magnet can be understood as its dimension perpendicular to the magnetic pole direction.

[0100] In a more preferred arrangement of this configuration, such as Figure 1A and Figure 1B As shown, the bias magnet 134 is arranged on the valve body 11 in an adjustable manner. Specifically, a stud is provided on one side of the valve body 11 in the axial direction of the second position of the active valve core 121, and an adjusting nut is sleeved on the stud. The bias magnet 134 is arranged on the adjusting nut. In this way, the axial position of the bias magnet 134 can be adjusted by turning the adjusting nut, thereby adjusting the relative position between the bias magnet 134 and the active magnet 131, thereby adjusting the magnitude of the second magnetic holding force. Since the second magnetic holding force determines the height of the lower liquid level in the water tank 100, the height of the lower liquid level can be adjusted.

[0101] It is understandable that by arranging the bias magnet 134 to be able to adjust the magnitude of the first magnetic holding force, the height of the upper liquid level can be adjusted.

[0102] It is understandable that by adjusting the magnetic field strength of the bias magnet 134, for example, by replacing the bias magnet 134 with a different magnetic field strength, the magnitude of the first magnetic holding force or the second magnetic holding force can also be adjusted, thereby achieving the purpose of adjusting the height of the upper liquid level or the height of the lower liquid level.

[0103] The second arrangement of the magnet components:

[0104] like Figure 2A and Figure 2BAs shown, the difference between this arrangement and the first arrangement is that in the first arrangement, the active magnet 131 is arranged around the positioning magnet 132, while in this arrangement, the positioning magnet 132 is arranged around the active magnet 131.

[0105] A third arrangement of the magnet components:

[0106] like Figure 3A and Figure 3B As shown, the magnet component includes an active magnet 131, a positioning magnet 132, and a bias magnet 134. The active magnet 131 is disposed on the active valve core 121, and the positioning magnet 132 is fixedly disposed on the valve body 11. The magnetic pole direction of the active magnet 131 is consistent with the moving direction of the active valve core 121. The positioning magnet 132 is located on one side of the radial direction of the active magnet 131, and the magnetic pole direction of the positioning magnet 132 is perpendicular to the magnetic pole direction of the active magnet 131. The active magnet 131 is composed of two magnet units stacked in the length direction, and the positioning magnet 134... Body 132 is composed of two magnetic units stacked in the thickness direction. The two magnetic units of the positioning magnet 132 have opposite magnetic poles facing the same direction. The thickness of the positioning magnet 132 is equal to the length of one magnetic unit of the active magnet 131. The bias magnet 134 is disposed on the valve body 11 and is located at the second position. The magnetic pole direction of the bias magnet 134 is perpendicular to the magnetic pole direction of the active magnet 131. When the active valve core 121 switches to the second position, the opposite magnetic poles of the active magnet 131 and the bias magnet 134 approach each other. Thus, as... Figure 3B As shown, after the active valve core 121 switches to the second position, the active magnet 131 approaches the bias magnet 134 and forms a magnetic attraction between them, as... Figure 3A As shown, after the active valve core 121 switches to the first position, the active magnet 131 moves away from the bias magnet 134 and the magnetic attraction almost disappears. Therefore, the bias magnet 134 makes the force that drives the active valve core 121 to switch from the first position to the second position to overcome the first magnetic holding force less than the force that drives the active valve core 121 to switch from the second position to the first position to overcome the second magnetic holding force. Therefore, the bias magnet 134 arranged in this way makes the first magnetic holding force less than the second magnetic holding force.

[0107] Accordingly, it can be understood that by aligning the bias magnet 134 with the same magnetic poles of the active magnet 131, the bias magnet 134 makes the force that drives the active valve core 121 from the first position to the second position to overcome the first magnetic holding force greater than the force that drives the active valve core 121 from the second position to the first position to overcome the second magnetic holding force. Therefore, the bias magnet 134 arranged in this way makes the first magnetic holding force greater than the second magnetic holding force.

[0108] The force-applying component 30 can be two magnets (not shown) respectively disposed on the active valve core 121 and the valve body 11, and the magnetic force between the two magnets is used to apply force to the active valve core 121; such as Figure 1A and Figure 1B As shown, the force-applying component 30 can also be a spring, which applies elastic force to the active valve core 121. More preferably, a spring with a very small elastic coefficient is selected as the force-applying component 30, and the initial compression of the spring is maximized. In this way, the spring can not only provide sufficient elastic force, but also the elastic force provided by the spring does not change much when the active valve core 121 switches between the first position and the second position and the spring extends or retracts.

[0109] The controlled mechanism includes various types. For example, the controlled mechanism is an electromagnetic controlled mechanism. Specifically, an electromagnetic sensor 123 is selected as the electromagnetic controlled mechanism. When the active valve core 121 switches between the first position and the second position, the electromagnetic sensor responds to the change in magnetic field caused by the position change of the active valve core 121 and sends an electrical signal. The switching valve 400 receives the electrical signal and acts to control the opening and closing of the water supply pipeline 500. Specifically, as shown in... Figure 4B As shown, when the active valve core 121 of the fluid control valve 300 switches from the first position to the second position, the electromagnetic sensor 123 sends a first electromagnetic signal to the electromagnetic actuator 403. The electromagnetic actuator 403 receives the first electromagnetic signal and drives the electromagnetic spindle 4031 to push against the diaphragm 402 of the switching valve 400 to close the valve port; Figure 4A As shown, when the active valve core 121 of the fluid control valve 300 switches from the second position to the first position, the electromagnetic sensor 123 sends a second electromagnetic signal to the electromagnetic actuator 403. The electromagnetic actuator 403 receives the second electromagnetic signal and drives the electromagnetic spindle 4031 away from the diaphragm 402, thereby opening the valve port by the thrust of the fluid on the diaphragm 402.

[0110] like Figure 1A and Figure 1BAs shown, the controlled mechanism can also be a fluid controlled mechanism. Specifically, the fluid controlled mechanism includes: a passive valve chamber 112, a passive valve core 122, a passive magnet 133, and a controlled port. The passive valve chamber 112 is disposed in the valve body 11. The passive valve core 122 is disposed in the passive valve chamber 112 and can move along the passive valve chamber 112. The passive magnet 133 is disposed in the passive valve core 122. The passive valve core 122 is driven by the active valve core 121 through magnetic force. The controlled port is disposed at the axial end of the passive valve chamber 112. The controlled port includes a first port 113 and a second port 114. The switching valve 400 is a diaphragm valve with a diaphragm 402 and a accumulator port 401. The first port 113 and the second port 114 are respectively connected to the downstream water supply pipeline of the switching valve 400 and the accumulator port 401 of the switching valve 400. Thus, when the active valve core 121 switches between the first position and the second position, the passive valve core 122 closes or opens the first port 113 and the second port 114. When the two ports are open, the accumulator port 401 of the diaphragm 402 valve releases pressure, thereby opening the valve port of the diaphragm 402, which in turn opens the water supply pipeline 500. When the two ports are closed, the accumulator port 401 accumulates pressure, thereby closing the valve port of the diaphragm 402, which in turn disconnects the water supply pipeline 500.

[0111] In some more preferred configurations, the controlled mechanism comprises multiple groups, for example, such as Figure 1A and 1B As shown, the controlled mechanism includes two sets. Specifically, each controlled mechanism includes a passive valve chamber 112, a passive valve core 122, a passive magnet 133, and a controlled port. One set of controlled mechanisms is used to control the switching valve 400, while the controlled port of the other set of controlled mechanisms is connected to other controlled devices 700 (e.g., other flow valves, switching valves 400, etc.) to control the other controlled devices 700.

[0112] The docking valve 600 can have various structural forms. In one structure, such as Figure 2A and Figure 2B As shown, the first docking mechanism 601 has a first docking valve core 603, and the second docking mechanism 602 has a second docking valve core 604. After the water tank 100 is placed on the base 200, the first docking valve core 603 and the second docking valve core 604 come into contact and open the water supply port and the water inlet port respectively, thereby opening the water injection channel 610. After the water tank 100 is removed from the base 200, the first docking valve core 603 and the second docking valve core 604 are separated and reset, thereby closing the water supply port on the base 200 and closing the water inlet port at the bottom of the water tank 100.

[0113] In some preferred structures, the two docking mechanisms are formed by stacking disc-shaped components 605 with water holes (the applicant's prior patent details the docking valve 600 of this structure). After the water tank 100 is placed on the base 200, the water tank 100 needs to be rotated by a certain angle to align the water holes and open the water injection channel 610. Before the water tank 100 is separated, it needs to be rotated in the opposite direction by a certain angle to misalign the water holes. The advantages of this docking valve 600 structure compared to the docking valve 600 with a docking valve 600 core are: 1. It can prevent water leakage from both the water tank 100 and the base 200 at the moment of separation from the base 200, which could lead to malfunction of the switch valve 400 and environmental pollution; 2. By arranging more water holes on the disc-shaped component 605, multiple sets of through holes can be formed between the water tank 100 and the base 200 (the water injection channel 610 is only one set of holes).
