[0015] 2) Insert the card to discharge water: Hold the IC card and insert it into the card slot, press the IC card downwards, so that the bottom of the IC card contacts the moving contact, and the connector connected to the moving contact moves downward along the strip groove, so that the moving contact moves downward, and the moving contact contacts the spring and the static contact, so that the manual normally open switch is closed, and the closed circuit in the water discharge control module is turned on.

[0017] The beneficial effects of the present invention are:
[0018] 1. The card-insertion type water intake control device provided by the present invention comprises a water outlet pipe and a waterproof shell. A water outlet control module is arranged in the waterproof shell. The module controls the normally closed solenoid valve to be energized to discharge water from the water outlet pipe after the card is inserted into the card slot. The module controls the normally closed solenoid valve to be de-energized to stop the water outlet pipe from discharging water when the water level in the water intake container reaches the upper limit. The water outlet control module and the water stop control module are integrated in the waterproof shell, so that the overall appearance and structure are simpler and more convenient to use. Manual card insertion water outlet and intelligent water stop are realized, which not only ensures that students can get enough water, but also effectively avoids the situation where water resources are wasted or scalding accidents occur due to excessive water intake. The module is highly practical and worthy of popularization and use.
[0019] 2. Specifically, the water outlet control module includes a power supply I, a sensor, a controller and a manual normally open switch. The normally closed solenoid valve is connected in series with the water outlet control module. Insert the IC card into the card slot, and then press the IC card downward to make the bottom of the IC card contact with the moving contact of the manual normally open switch, so that the moving contact moves downward, the manual normally open switch is closed, and the closed loop in the water outlet control module is turned on. At the same time, the magnetic sensor (infrared sensor) senses the magnetic sheet in the IC card (the infrared sensor senses the human hand) and transmits the signal to the controller. The controller controls the normally closed solenoid valve to open, so that boiling water flows out from the water outlet pipe, avoiding the boiling water flowing out at the moment the IC card is inserted into the card slot, which may easily cause scalding to the first-time user. The boiling water can only flow out by pressing the IC card downward to make the moving contact slide downward along the waterproof shell to close the manual normally open switch, thereby further improving the safety of water collection.
[0020] 3. Specifically, the heat-conductive and electrically conductive component in the water-stop control module can be adjusted according to the shape and capacity of the water intake container by adjusting the length of the bellows so that the contact head at the end thereof extends into the upper limit of the water level of the water intake container. When the water level in the water intake container reaches the upper limit, the water-stop control module can automatically control to stop the water discharge, thereby improving the versatility of the device. Moreover, when the heat-conductive and electrically conductive component is not in use, the heat-conductive and electrically conductive component can be positioned on the clamping ring outside the waterproof shell, so that the overall structural design is more reasonable and the storage property is better.
[0021] In summary, the card-type water intake control device has a simple overall structure, strong versatility, and is easy to use. It realizes manual card insertion and intelligent water shut-off, which not only ensures that students can get enough water, but also effectively avoids excessive water intake that causes water resource waste or scalding accidents.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0030] The specific implementation scheme of the present invention is: Figure 1 and Figure 2As shown, a card-insertion water intake control device includes a water outlet pipe 1 and a waterproof housing 2. A normally closed electromagnetic valve 3 is arranged on the water outlet pipe 1, a card slot 4 is arranged on the waterproof housing 2, and a water outlet control module 5 and a water stop control module 6 are arranged in the waterproof housing 2. When an IC card is inserted into the card slot 4, the water outlet control module 5 can energize the normally closed electromagnetic valve 3 and make the boiling water flow out of the water outlet pipe 1. When the water level in the water intake container reaches the upper limit, the water stop control module 6 can de-energize the normally closed electromagnetic valve 3 and stop the boiling water from flowing out. The device integrates the water outlet control module 5 and the water stop control module 6 in the waterproof housing 2, making the overall appearance structure simpler and more convenient to use, and realizing manual card insertion water outlet and intelligent water stop, which not only ensures that students can get enough water, but also effectively avoids the situation where excessive water intake causes water resource waste or scalding accidents. It is highly practical and worthy of popularization.
[0031] Specifically, Figure 2As shown, the water outlet control module 5 includes a power supply I51, a sensor 52, a controller 53 and a manual normally open switch 54 connected in series with the normally closed solenoid valve 3. The sensor 52 is connected to the normally closed solenoid valve 3 through the controller 53. The sensor 52 is arranged at the card slot 4. The sensor 52 can be set as a magnetic sensor or an infrared sensor. When a person holds an IC card and inserts it into the card slot 4, the magnetic sensor senses the magnetic sheet in the IC card (the infrared sensor senses the hand), and transmits the sensing signal to the controller, and the controller controls the action of the normally closed solenoid valve. The manual normally open switch 54 is arranged at the bottom of the card slot 4, and the manual normally open switch 54 includes a spring piece 541, a moving contact 542 and a static contact 543. The middle part of the spring piece 541 is fixed to the upper and lower ends of the waterproof housing 2 through a fixed shaft 544. A through hole is arranged in the middle part of the spring piece 541, and the fixed shaft 544 is interference fit with the through hole; the moving contact 542 and the static contact 543 are respectively arranged on the upper and lower sides of one end of the spring piece 541, and the moving contact 542 is slidably connected to the waterproof housing 2. Specifically, the waterproof housing 2 is provided with a strip groove 21, and the moving contact 5 The end of 42 is slidably matched with the strip groove 21 through a connecting piece, and the connecting piece includes a bolt and a nut. One end of the bolt is passed through the strip groove 21 and connected and fixed with the end of the moving contact 542. The other end of the bolt is limited by the nut. The bolt and the strip groove 21 are gap-matched. The bolt slides up and down along the strip groove 21 to drive the moving contact 542 to move up and down. The bolt and the nut can be set as lightweight plastic parts, so that the weight of the moving contact 542 and the connecting piece is less than the weight of the spring 541. In the initial state, the moving contact 542 is connected to the upper end of the spring 541. The moving contact 542 is touched but will not be pressed down to contact the static contact 543, so that the manual normally open switch 54 is in the off state; the upper end of the moving contact 542 extends out from the bottom of the slot 4, and the static contact 543 is fixed on the waterproof shell 2. Specifically, the waterproof shell 2 is connected to the U-shaped shell 7 outside to form the slot 4, and the bottom of the waterproof shell 2 is provided with an extension portion 24, and the upper end of the extension portion 24 is in sealing contact with the bottom end of the U-shaped shell 7, and the upper end of the extension portion 24 is provided with a strip opening 241 perpendicular to the horizontal direction, and the moving contact 542 passes through the strip opening 241.The working principle of the water outlet control module 5 is: insert the IC card into the card slot 4, then manually press the IC card downward gently, so that the bottom of the IC card contacts the moving contact 542, so that the connecting piece connected to the moving contact 542 moves downward along the strip groove 21, so that the moving contact 542 moves downward, so that the moving contact 542 contacts the spring 541 and the static contact 543, so that the manual normally open switch 54 is closed, so that the closed loop in the water outlet control module is turned on, and at the same time the magnetic sensor (infrared sensor) senses the magnetic sheet in the IC card (the infrared sensor senses the human hand), and transmits the signal to the controller 53, and the controller 53 controls the normally closed solenoid valve 3 to open. (The controller controls the action of the solenoid valve according to the signal of magnetic induction and infrared induction, which belongs to the prior art. The principle of the controller is the same as that of the existing IC card water control machine. Its technical parameters include: Card reader type: MiFare one, card reading distance: 2-7cm, card reading speed: <1s, working voltage: DC12V, working power: 5W, standby power: <1W, billing accuracy: 1 cent - 1 second, data storage: 30,000 pieces of streaming storage, external dimensions: 140mm*100mm*40mm), so that the boiling water flows out from the water outlet pipe 1, avoiding the boiling water flowing out at the moment the IC card is inserted into the card slot 4, which may easily cause scalding to the first user. Only by pressing the IC card downward to make the moving contact 542 slide downward along the waterproof shell 2 to close the manual normally open switch 54 can the boiling water flow out, further improving the safety of water collection.
[0032] like Figure 2As shown, a water-stop control module 6 is arranged above the other end of the above-mentioned shrapnel 541, and the water-stop control module 6 includes a power supply II 61, a heat-conductive conductive member 62, a normally closed thermal switch 63, a coil 64, an iron core 65 and an iron block 66. The coil 64 is wound around the iron core 65, and the power supply II 61 is connected in series with the heat-conductive conductive member 62, the normally closed thermal switch 63 and the coil 64 in sequence. The heat-conductive conductive member 62 extends out of the waterproof housing 2; the heat-conductive conductive member 62 is inserted into the water intake container so that the end of the heat-conductive conductive member 62 is located below the water level line of the water intake container. When the boiled water in the water intake container reaches the upper limit of the water level, the temperature of the boiled water can be transmitted to the normally closed thermal switch 63 through the heat-conductive conductive member 62. The normally closed thermal switch 63 can open by sensing the temperature of the heat-conductive conductive member 62 when its temperature reaches the operating temperature of the normally closed thermal switch 63. The iron core 65 One end of is connected to the iron block 66 through an insulating wire. The weight of the iron block 66 is greater than the weight of the spring 541, which is enough to make the other end of the spring 541 tilt up when the iron block 66 falls on one end of the spring 541, so that the spring 541 is separated from the static contact 543, and the manual normally open switch 54 is in an open state. The length of the insulating wire is greater than the vertical distance between the end of the iron core 65 and the spring 541. When the normally closed thermal switch 63 is disconnected and the closed circuit of the water stop control module 6 is disconnected, the coil 64 loses power, the magnetism of the iron core 65 disappears, and the iron block 66 is separated from the iron core 65 and falls. The iron block 66 is opposite to one end of the spring 541. Since the length of the insulating wire is greater than the vertical distance between the end of the iron core 65 and the spring 541, the iron block 66 can collide with one end of the spring 541, so that the circuit of the water outlet control module 5 is disconnected and the water outlet stops.
[0033] In addition, the waterproof housing 2 is optimally provided with a positioning chamber 22 for accommodating the power supply II 61, the normally closed thermal switch 63, the coil 64 and the iron core 65, and a guide plate 23 for making the iron block 66 collide with one end of the spring 541 after falling, so that when the iron block 66 falls, it contacts the spring 541 under the guidance of the guide plate 23, so that the action response is more accurate. The material of the heat-conducting and electrically conductive member 62 is set to be a heat-conducting plastic, such as Figure 1 and Figure 2 As shown, the heat-conducting and electrical-conducting member 62 includes a bellows 621, a positioning section 622 connected to one end of the bellows 621, and a contact head 623 connected to the other end of the bellows 621. The positioning section 622 is connected in series with the normally closed thermal switch 63 through a wire. The bellows 621 can adjust the length of the heat-conducting and electrical-conducting member 62. According to the shape and capacity of the water intake container, the length of the bellows 621 can be adjusted so that the contact head 623 at its end extends into the upper limit of the water level of the water intake container, thereby improving the versatility of the device. The diameter of the positioning section 622 is larger than the outer diameter of the bellows 621. A clamping ring 8 is also provided outside the waterproof housing 2. Figure 1 and Figure 3As shown, the snap ring 8 includes an opening 81 and a clamping portion 82, the outer diameter of the bellows 621 is larger than the caliber of the opening 81 and smaller than the caliber of the clamping portion 82, the caliber of the clamping portion 82 is smaller than the diameter of the positioning section 622, when the heat-conducting and electrically conductive member 62 is not used, the bellows 621 of the heat-conducting and electrically conductive member 62 can be clamped in the clamping portion 82 through the opening 81, after letting go, the positioning section 622 is positioned at the upper end of the snap ring 8, and its overall structural design is more reasonable and has better storage performance. A display screen connected to the controller 53 can also be provided outside the waterproof housing 2 to display the balance of the IC card.
[0034] When no water is taken, the water stop control module 6 forms a conductive loop, so that the iron core 65 generates magnetism and attracts the iron block 66. The method of using the card-insertion water intake control device includes the following steps: 1) Preparation before card insertion: First, hold the heat-conductive and electrically conductive member 62, adjust the length of the heat-conductive and electrically conductive member 62, and insert its contact head 623 into the position where the upper limit of the water level of the bottle mouth of the water intake container is downward; 2) Insert the card to discharge water: Hold the IC card and insert it into the card slot 4, gently press the IC card downward, so that the bottom of the IC card contacts the moving contact 542, so that the connecting member connected to the moving contact 542 moves downward along the strip groove 21, so that the moving contact 542 moves downward, so that the moving contact 542 contacts the spring 541 and the static contact 543, so that the manual normally open switch 54 is closed, so that the closed circuit in the water outlet control module is turned on, and at the same time, the magnetic sensor (infrared sensor) senses the magnetic sheet in the IC card (the infrared sensor senses the human hand), and transmits the signal to the controller 53, and the controller 53 controls the normally closed electromagnetic The valve 3 is opened to allow the boiling water to flow out of the water outlet pipe 1; 3) The water supply is automatically stopped after the water is full: when the water in the water collection container contacts the contact head 623 of the heat-conductive conductive element 62, the temperature of the boiling water is transmitted to the heat-conductive conductive element 62, and the normally closed thermal switch 63 senses the temperature of the heat-conductive conductive element 62. When the temperature of the heat-conductive conductive element 62 reaches the operating temperature of the normally closed thermal switch 63, the normally closed thermal switch 63 is opened, the magnetism of the iron core 65 disappears, and the iron block 66 is separated from the iron core 65 and falls to one end of the spring 541 under the traction of the insulating wire, so that the other end of the spring 541 is tilted, and the spring 541 is disconnected from the static contact 543, so that the manual normally open switch 54 is disconnected, and the closed circuit of the water outlet control module 5 is disconnected, so that the normally closed solenoid valve 3 loses power and stops discharging water, and at the same time gives the human hand an upward elastic force, at this time, the hand can be released, and then the IC card is taken out from the card slot 4.
[0035] In summary, the card-type water intake control device has a simple overall structure, strong versatility, and is easy to use. It realizes manual card insertion and intelligent water shut-off, which not only ensures that students can get enough water, but also effectively avoids excessive water intake that causes water resource waste or scalding accidents. It is highly safe and practical, and is worthy of popularization and use.

5. A method for using the card-insertion water intake control device according to any one of claims 1 to 4, characterized in that: The following steps are involved: 1) Preparation before card insertion: Hold the heat-conducting and electrically conductive member (62), adjust the length of the heat-conducting and electrically conductive member (62), and insert its contact head (623) into the position where the upper limit of the water level of the bottle mouth of the water collection container is downward; 2) Inserting the IC card to discharge water: insert the IC card into the card slot (4), press the IC card downward, so that the bottom of the IC card contacts the moving contact (542), and the connecting piece connected to the moving contact (542) moves downward along the strip groove (21), so that the moving contact (542) moves downward, so that the moving contact (542) contacts the spring (541) and the static contact (543), so that the manual normally open switch (54) is closed, so that the closed circuit in the water discharge control module is turned on, and at the same time, the sensor transmits the sensing signal to the controller (53), and the controller (53) controls the normally closed solenoid valve (3) to open, so that boiling water flows out of the water discharge pipe (1); 3) Automatic water shut-off after water is full: When the water in the water collection container contacts the contact head (623) of the heat-conducting and electrically conductive member (62), the temperature of the boiling water is transmitted to the heat-conducting and electrically conductive member (62), and the normally closed thermal switch (63) senses the temperature of the heat-conducting and electrically conductive member (62). When the temperature of the heat-conducting and electrically conductive member (62) reaches the operating temperature of the normally closed thermal switch (63), the normally closed thermal switch (63) is opened, causing the magnetism of the iron core (65) to disappear, and causing the iron block (66) to separate from the iron core (65). 65) and falls to one end of the spring (541) under the traction of the insulating wire, causing the other end of the spring (541) to tilt up, disconnecting the spring (541) from the static contact (543), thereby disconnecting the manual normally open switch (54), disconnecting the closed circuit of the water outlet control module (5), de-energizing the normally closed solenoid valve (3), stopping the water outlet pipe (1) from discharging water, and giving the hand an upward elastic force, at which time the hand can be released and the IC card can be removed from the card slot (4).
