Technical Field

[0001] The utility model relates to the technical field of kitchen gas control, in particular to a gas control device suitable for kitchens. Background Art

[0002] As a clean and efficient energy source, gas is widely used in residential, industrial, and commercial sectors. Traditional gas systems are facing obsolescence. With the advent of digitalization and intelligentization, gas safety faces industrial transformation and upgrading. When a residential user is at the scene of a gas leak, they can detect the leak by sensing the odor and shut off the gas. However, if a gas leak occurs while the user is away from the site, they cannot detect it in time, resulting in immeasurable consequences. Therefore, a smart gas system is needed that can effectively improve the safety and protection of gas use. Utility Model Content

[0007] The output end of the central controller is electrically connected to a wire, and one end of the wire is electrically connected to the input end of the solenoid valve.

[0008] Furthermore, a radar detection sensor is embedded in the upper center position of the front of the central controller, and a cooking button and a bathing button are embedded in the lower end of the front of the central controller. A first LED indicator light and a second LED indicator light are respectively provided above the cooking button and the bathing button.

[0009] Furthermore, a protective shell is provided on the outer surface of the central controller, and slots are provided in the middle sections of the inner walls of both sides of the protective shell, and the middle protrusions on both sides of the central controller slide in the slots with damping.

[0010] Furthermore, it also includes an anti-theft structure, which includes a buzzer, a pressure sensor, a connecting column and a contact head. The buzzers are symmetrically embedded in the back end of the protective shell, and the pressure sensor is embedded in one end of the buzzer. One end of the connecting column passes through the buzzer, the pressure sensor, the protective shell and the back end of the central controller and is fixed, and the other end of the connecting column is threaded with a contact head.

[0011] Furthermore, a rubber pad is bonded to one side of the abutment head opposite to the pressure sensor, and the abutment head is configured to be hexagonal.

[0012] Furthermore, the gas control structure also includes a second gas riser, a first gas branch and a second gas branch. The second gas riser is threadedly connected to the other side of the upper part of the gas meter, and the upper end of the second gas riser is threaded with the first gas branch, and the upper part of one side of the outer surface of the second gas riser is threaded with the second gas branch.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] First, this utility model utilizes a central controller in conjunction with a solenoid valve, using a radar sensor to detect whether someone is in front of the stove. If a person is detected, the central controller opens the solenoid valve to connect the gas, and the first LED indicator lights up. If the radar sensor doesn't detect a person in front of the stove within ten minutes, the central controller closes the solenoid valve, cutting off the gas. If the user wishes to bathe with gas, they press the bath button, at which point the second LED indicator lights up and the central controller opens the solenoid valve. If the radar sensor doesn't detect a person in front of the stove or the bath button is pressed after an hour, the central controller closes the solenoid valve, cutting off the gas. This gas control method helps reduce the probability of gas leaks and greatly improves gas safety.

[0015] 2. Based on the above beneficial effects, while the protective shell is used to protect the central controller externally, if the central controller is taken, the sliding central controller will be linked to the connecting column to move its position after being subjected to force. After the contact head contacts the pressure sensor, the pressure sensor can be used to control the buzzer through the central controller to sound, giving an alarm, thereby preventing theft and being convenient to use.

The cooking button 52 and the bathing button 53 are used to control cooking and bathing. The first LED indicator 55 and the second LED indicator 56 are used to indicate the cooking and bathing status respectively. The outer surface of the central controller 5 is provided with a protective shell 54, and the middle section of the two side walls of the protective shell 54 is provided with a groove. The middle part of the two sides of the central controller 5 has a damping sliding in the groove. The protective shell 54 provides external protection for the central controller 5, which can reduce the probability of damage and save the cost of use. The damping sliding of the protrusion in the groove ensures that the central controller 5 can be operated. The gas control structure also includes a second gas riser 3, a first gas branch pipe 7 and a second gas branch pipe 8. The second gas riser 3 is threadedly connected to the other side of the upper part of the gas meter 1, and the upper end of the second gas riser 3 is threaded with the first gas branch pipe 7, and the upper part of one side of the outer surface of the second gas riser 3 is threaded with the second gas branch pipe 8.

The contact between the contact head 543 and the pressure sensor 544 can activate the buzzer 541 to alarm. A rubber pad is adhered to the side of the contact head 543 opposite to the pressure sensor 544, and the contact head 543 is set to a hexagonal shape. The rubber pad can avoid hard contact between the contact head 543 and the pressure sensor 544 to cause damage. The hexagonal setting of the contact head 543 meets the application of disassembly and assembly force.

[0029] Working principle: When the central controller 5 is taken out from the protective shell 54, the linkage connecting column 542 moves its position. After the moving contact head 543 contacts the pressure sensor 544, the pressure sensor 544 under force transmits data wirelessly to the central controller 5 to control the buzzer 541 to alarm, thereby achieving the anti-theft purpose. This solution can protect the central controller 5 from theft and appearance, reduce the probability of damage and loss, and save costs.
