Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a water purifier with a gas leakage detection function. Background Technique

[0002] A water purifier, also known as a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water quality according to the usage requirements of water. Generally, the water purifier mentioned usually refers to a small purifier for household use.

[0003] Existing water purifiers, as Figures 1-2 shown, three filters are adopted inside the water purifier body, and the filters are respectively a PP cotton carbon rod composite filter, a granular activated carbon filter, and an RO reverse osmosis membrane filter. However, the function of the water purifier is only to purify water. Since such water purifiers are generally installed inside a cabinet adjacent to a gas pipe, the water purifier does not have an alarm reminder function for excessive gas concentration, resulting in occupying a certain space inside the cabinet, but without adding functions and unable to meet the needs of users. Although a small number of them will have an alarm for excessive gas concentration, the water purifier is inside the cabinet and the cabinet door is generally in a closed state, so the sound transmitted is too small to easily alert people in the family. Content of the Utility Model

The microcontroller is respectively in signal connection with the motor and the electromagnet. The output shaft of the motor penetrates into the interior of the housing and is fixed to the driving bevel gear.

[0009] Furthermore, the shaft rod is connected to the inner rear side of the housing through a bearing. The driven bevel gear is fixed to the outside of the shaft rod. The driven bevel gear is located in front of the driving bevel gear and is in meshing connection with the driving bevel gear. There are a pair of rope pulleys which are respectively fixed to the left and right sides of the outside of the shaft rod. There are a pair of pulling ropes which are respectively wound around the outside of the rope pulleys in a one-to-one correspondence. The push plate is fixed between the ends of the pulling ropes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Please refer to Figures 3-5 , a water purifier with a gas leakage detection function, including a water purifier body 1. A row of supporting feet 2 are fixed on both sides of the lower end of the water purifier body 1. The lower ends of the supporting feet 2 are fixedly connected with suction cups 3. When the water purifier body 1 is placed in the kitchen cabinet, the suction cups 3 can suck the ground to ensure the stability of the placement of the water purifier body 1. Then the water purifier body 1 can be connected to the water tank and the faucet through a water pipe, so that the kitchen water can be filtered and purified through the internal filter element. The model of the water purifier body 1 is WK-Q4RO3B-4. Since the water purification principle of the water purifier body 1 is the prior art, it will not be elaborated in this application;

[0022] A gas detection mechanism is installed at the upper end of the top cover of the water purifier body 1. The gas detection mechanism includes a machine box 4, a gas sensor 5, an alarm 6, a power supply 9, a control circuit board 10 and a door-pushing component. The machine box 4 is fixed to the top cover of the water purifier body 1. The gas sensor 5 is installed inside the machine box 4. The air inlet end of the gas sensor 5 penetrates through the side surface of the machine box 4. The alarm 6 is located on one side of the gas sensor 5 and is installed inside the machine box 4. The sound-emitting end of the alarm 6 penetrates through the side surface of the machine box 4. The power supply 9 and the control circuit board 10 are installed inside the machine box 4. The door-pushing component is installed on the front side inside the machine box 4. The gas sensor 5 is signal-connected to the control circuit board 10. The control circuit board 10 is signal-connected to the alarm 6. The control circuit board 10 includes a substrate and a microcontroller and an NB-IOT module installed on the substrate. The gas sensor 5 is signal-connected to the microcontroller. The microcontroller is respectively signal-connected to the NB-IOT module and the alarm 6. By setting the gas detection mechanism at the upper end of the water purifier body 1, when the gas sensor 5 detects the gas leaked from the gas pipe, it transmits a signal to the microcontroller of the control circuit board 10. The microcontroller controls the alarm 6 and the power supply 9 to be energized to give an alarm. At the same time, it can also transmit a signal to the NB-IOT module of the control circuit board 10. The NB-IOT module then sends a message to the user's mobile phone to remind that there is a gas leak at home. In this way, even if the user is outside, they can receive the alarm;

[0023] The control circuit board 10 is connected to the door-pushing assembly. The door-pushing assembly includes a push plate 7, a housing 8, a motor 11, a driving bevel gear 12, a shaft rod 13, a driven bevel gear 14, a rope pulley 15, a pulling rope 16, a ratchet and pawl assembly 19, and an electromagnet 20. The housing 8 is fixed to the machine box 4. The motor 11 is fixedly installed at the rear end of the housing 8. There are a pair of electromagnets 20 which are respectively fixedly installed on the left and right sides of the inner rear end of the housing 8. The microcontroller is respectively in signal connection with the motor 11 and the electromagnet 20. The output shaft of the motor 11 penetrates into the interior of the housing 8 and is fixed to the driving bevel gear 12. The shaft rod 13 is connected by bearings at the rear side inside the housing 8. The driven bevel gear 14 is fixed to the outside of the shaft rod 13. The driven bevel gear 14 is located in front of the driving bevel gear 12 and is meshed and connected with the driving bevel gear 12. There are a pair of rope pulleys 15 which are respectively fixed to the left and right sides of the outside of the shaft rod 13. There are a pair of pulling ropes 16 which are respectively wound around the outside of the rope pulleys 15 in a one-to-one correspondence. The push plate 7 is fixed between the ends of the pulling ropes 16. The front end of the push plate 7 movably penetrates through the front parts of the housing 8 and the machine box 4. Convex platforms 17 are fixed to both the left and right ends of the inner wall of the housing 8. The convex platforms 17 are located in front of the shaft rod 13. A spring 18 is connected between the front end of the convex platform 17 and the rear end of the push plate 7. There are two groups of ratchet and pawl assemblies 19 which are respectively installed on the left and right sides of the outside of the shaft rod 13. The ratchet and pawl assemblies 19 are located outside the rope pulleys 15. The ratchet and pawl assembly 19 includes a ratchet box, a ratchet, a pawl, and an elastic member. The ratchet box is fixed to the inner wall of the housing 8. The shaft rod 13 movably penetrates through the ratchet box. The ratchet is located inside the ratchet box and is fixed to the outside of the shaft rod 13. The pawl is rotatably connected to the rear side inside the ratchet box. The pawl is connected to the ratchet. The elastic member is connected between the rear end of the pawl and the rear end inside the ratchet box. The pawl is made of iron. The electromagnet 20 is located directly behind the ratchet and pawl assembly 19. When the user is sleeping at night, if the gas sensor 5 detects the gas leaking from the gas pipe, while the microcontroller controls the alarm 6 to sound an alarm and the NB-IOT module to send information, it can also control the electromagnet 20 to be energized and attract the pawl, so that the pawl rotates and is no longer connected to the ratchet. The pawl can also squeeze the elastic member. After that, the ratchet is no longer self-locked. The spring 18 in a compressed state pushes the push plate 7 forward. At least four springs 18 can be used to increase the pushing force of the push plate 7. At this time, the pulling rope 16 is unwound from the outside of the rope pulley 15, and the push plate 7 moves out of the machine box 4 and pushes open the cabinet door. At this time, the bottom of the water purifier body 1 is sucked by the suction cup 3, and the water purifier body 1 will not be displaced. After the cabinet door is opened, the alarm sound emitted by the alarm 6 can be transmitted out of the cabinet to remind the sleeping user. In this way, the versatility of the water purifier body 1 is improved;

[0024] When the gas sensor 5 does not detect gas, the microcontroller controls the alarm 6 to cut off power and the electromagnet 20 to cut off power. The pawl is no longer attracted, and then it will be reset and connected to the ratchet through the elastic member. However, the microcontroller will also control the motor 11 to start and stop after a period of time. As the motor 11 drives the driving bevel gear 12 to rotate, the driving bevel gear 12 meshes with the driven bevel gear 14, driving the shaft rod 13 to rotate. The shaft rod 13 drives the rope pulley 15 and the ratchet to rotate. The ratchet and the pawl do not prevent the rotation of the shaft rod 13 when the rope pulley 15 is winding, but can lock the shaft rod 13 when the rope pulley 15 is unwinding to prevent the rope pulley 15 from unwinding. In this way, the rope pulley 15 will wind the pulling rope 16. After the pulling rope 16 pulls the push plate 7 into the inner part of the housing 8, it will compress the spring 18. Then, as the motor 11 stops, through the cooperation of the ratchet and the pawl, the rope pulley 15 will not unwind automatically and the push plate 7 will not move forward, so it can be reused.
