The gas stove is one of the most commonly used electric appliances in daily life and plays an important role in the cooking process of people. People may leave the kitchen due to external interference such as telephone or forget to turn off the gas stove after cooking, which may result in waste of gas, and may damage the cooker in serious cases, even cause fire, and threaten the personal safety of users.

Based on this, the embodiment of the utility model provides a gas-cooker switch and gas-cooker is proposed to alleviate some users in the technique because forget and close the gas-cooker, lead to the waste of gas, probably destroy the pan when serious, arouse the conflagration even, cause dangerous technical problem.

The present embodiment provides a gas stove switch, as shown in fig. 1 to 3, comprising a regulating valve 100, a valve shaft 110 motion recognition mechanism and a control valve set 400; the regulating valve 100 comprises a valve shaft 110 and a first microswitch 120, wherein the valve shaft 110 is used for rotating and regulating the degree of heating, and the first microswitch 120 is used for igniting; the valve shaft 110 action recognition mechanism is arranged on the regulating valve 100 and comprises a gear ring 200 and a second microswitch 300, the gear ring 200 is coaxially fixed and sleeved on the valve shaft 110, the second microswitch 300 is arranged on the periphery of the gear ring 200, and the gear ring 200 can rotate along with the valve shaft 110 to be closed and opened with the second microswitch 300; the control valve set 400 is electrically connected with the second microswitch 300 and is connected with the gas path of the gas stove, and whether the gas path of the gas stove is closed or not is judged by acquiring the information of the on/off of the second microswitch 300 and the gear ring 200.

Through the embodiment of the utility model provides a, when the user left or forgot to close the gas-cooker after the culinary art finishes at the in-process of culinary art, whether the valve shaft 110 rotated through the information that acquires the closure of second micro-gap switch 300 and gear ring 200, disconnection, if valve shaft 110 did not rotate, whether the length of judging that valve shaft 110 did not rotate exceeded the predetermined settlement length in advance in the valve group 400, if exceeded, then closed the gas-cooker.

Specifically, the first microswitch 120 is used only for ignition, regardless of the valve shaft 110 motion recognition mechanism. When the valve shaft 110 rotates, the gear ring 200 fixed to the valve shaft 110 rotates synchronously, and is continuously switched between the closed state and the open state with the second microswitch 300 disposed on the outer circumferential side of the gear ring 200 during the rotation. The control valve assembly 400 judges whether the gas path of the gas range needs to be closed by judging the state of the second microswitch 300.

The gear ring 200 is coaxially fixed to the valve shaft 110, and the gear ring 200 and the valve shaft 110 may be connected by a key or other connection methods as long as the function of axially fixing the gear ring 200 is achieved, and the rotational motion and the torque of the valve shaft 110 are transmitted to the gear ring 200.

The second microswitch 300 may be provided at any position on the outer peripheral side of the gear ring 200, and the gear ring 200 may be in contact with the second microswitch 300 during rotation with the valve shaft 110. The specific position can be determined according to the positions of other parts in the gas stove.

In this embodiment, the information on the on/off of the second microswitch 300 and the gear ring 200 indicates whether the second microswitch 300 is switched between on and off. For example, if the second microswitch 300 remains closed or open for a period of time, this indicates that the valve shaft 110 has not rotated during the period of time.

In this embodiment, the regulator valve 100 is a stopcock valve. It should be noted that the adjusting valve 100 is not limited to the plug valve used in the present embodiment as long as it can adjust the fire of the gas range by rotating the valve shaft 110.

As shown in fig. 3, gear teeth for closing the second microswitch are uniformly distributed on the outer peripheral wall of the gear ring 200. The gear ring 200 and the gear teeth may be integrally formed, or may be fixedly connected with each other in a split structure. In this embodiment, the gear ring 200 and the gear teeth are integrally formed. When the valve shaft 110 rotates, the gear ring 200 thereon rotates, and the gear teeth of the gear ring 200 also rotate, so as to contact the second microswitch 300.

Specifically, the teeth of a cogwheel evenly distributed is at ring gear 200 periphery wall, and "evenly distributed" here does not require the interval between every two adjacent teeth of a cogwheel to all be identical, as long as guarantee that the interval between every two adjacent teeth of a cogwheel differs lessly, can not appear the very big condition of certain two adjacent teeth of a cogwheel intervals. This is because if there are two adjacent gear teeth with a large distance, the user may rotate the plug valve, so that during the rotation of the valve shaft 110, the two gear teeth with a large distance are located at the side where the second microswitch 300 is located, and during the rotation, the second microswitch 300 is always located in the distance and does not contact with the gear teeth, so that the valve shaft 110 rotates, the state of the second microswitch 300 is always off, and the second microswitch 300 cannot accurately determine whether the valve shaft 110 rotates.

It should be noted that the gear ring 200 and the gear teeth thereon form a structure like a gear, and may not have the transmission function of the gear.

In this embodiment, the radius of the tip of the gear tooth is greater than the distance between the second microswitch 300 and the center of the gear ring 200; the radius of the root end of the gear teeth is smaller than the distance between the second microswitch 300 and the centre of the gear ring 200. Specifically, the radius of the tip of the gear refers to the length from the center of a circle of the gear tooth to the tip of the gear; the radius of the root end of the gear refers to the length from the center of the gear teeth to the root end of the gear. When the tip of the gear rotates to the position of the second microswitch 300, the tip will contact with the second microswitch 300 to make the second microswitch 300 in a closed state, after the tip leaves the position of the second microswitch 300, the next tip adjacent to the tip comes before the position of the second microswitch 300, because the radius of the root end of the gear teeth is smaller than the distance between the second microswitch 300 and the center of the gear ring 200, the gear does not contact with the second microswitch 300, and the state of the second microswitch 300 is in an open state. In this case, when the user uses the gas stove to switch the plug valve between different gears, the second microswitch 300 can be switched back and forth between the closed state and the open state; when the cock valve is not rotated, the second microswitch 300 will remain in the closed or open state.

In this embodiment, the valve shaft 110 is provided with a clamping groove, the two sides of the gear ring are respectively sleeved with a split retaining ring 500 along the axis of the valve shaft 110, and the split retaining ring 500 is clamped in the clamping groove. Specifically, the clamping grooves are formed from the outer peripheral wall of the valve shaft 110 to the axis, the two clamping grooves are the same in size, the distance between the upper surface and the lower surface of the two clamping grooves is equal to the thickness of the split retainer ring 500, and the distance between the lower surface of the upper clamping groove and the upper surface of the lower clamping groove is equal to the thickness of the gear ring 200. In this case, both the gear ring 200 and the split collars 500 can remain stationary in the direction of the valve shaft 110. The gear ring 200 is fixed in the middle by the two split collars 500 without axial displacement, which ensures that the gear ring 200 can only rotate around the valve shaft 110, thereby always keeping on a horizontal plane with the second microswitch 300.

In this embodiment, the gas range switch further includes a mounting plate 600, and the second microswitch 300 is mounted on the mounting plate 600. The second microswitch 300 and the mounting plate 600 may be connected by a screw or other connection means which prevents them from being displaced relative to each other.

The regulator valve 100 further includes an upper cover plate on which the mounting plate 600 is fixedly disposed. The mounting plate 600 and the upper cover plate may be fixed by screws or may be fixedly connected by other methods.

In this embodiment, the control valve assembly 400 includes a controller 410 with a timing function, and the controller 410 starts timing every time the second micro switch 300 is switched between the closed state and the open state. Specifically, the timing module of the controller 410 starts timing after receiving the start message. The start information means that a timing module reset instruction is received. The reset instruction of the timing module can be sent out under two conditions, one is when the gas stove is started; the other is that during use by the user, the controller 410 detects that the second microswitch 300 is switching between the closed and open states, which indicates that the user is adjusting the stopcock valve and the controller 410 needs to count again.

Optionally, the control valve assembly 400 further includes a main solenoid valve for connecting with a gas circuit of the gas stove, and the controller 410 is electrically connected with the second micro switch 300 and the main solenoid valve respectively; the controller 410 is set to have a first set time period, the controller 410 compares the timing time period with the first set time period inside the controller 410, and when the timing time period is longer than the first set time period, the controller 410 controls the main solenoid valve to close the gas path.

Optionally, as shown in fig. 4, the control valve assembly 400 further includes a big fire solenoid valve 700 and a small fire solenoid valve 710 for connecting with a gas path of the gas stove, and the controller 410 is electrically connected to the second micro switch 300, the big fire solenoid valve 700 and the small fire solenoid valve 710, respectively; the controller 410 is set with a first set time period and a second set time period, wherein the first set time period is longer than the second set time period; when the timing duration is longer than a second set duration, the controller 410 controls the big fire solenoid valve 700 to close and keeps the small fire solenoid valve 710 to continue opening so as to adjust the fire of the gas stove to be small fire, and continues to time; when the timed duration is longer than the first set duration, the controller 410 controls the soft fire solenoid valve 710 to close the gas path.

It should be noted that, in general, the first set duration and the second set duration are factory settings, and the first set duration is greater than the second set duration.

The embodiment also provides a gas stove, as shown in fig. 4, comprising the gas stove switch.

The embodiment of the utility model provides a working process explanation of gas-cooker switch is introduced below:

in the present embodiment, as shown in fig. 5, when the user starts cooking, the gas stove is started, the control valve set 400 is started accordingly, and the controller 410 in the control valve set 400 instructs the built-in timing module to reset and time. When the timing module starts timing, the controller 410 determines whether the valve shaft 110 rotates by detecting and determining whether the on/off state of the second microswitch 300 changes, and if the state of the second microswitch 300 changes, the valve shaft 110 rotates, and the timing module resets; if the state of the second microswitch 300 is not changed, which indicates that the valve shaft 110 is not rotating, the timing module continues to count time and continuously detects the state of the valve shaft 110.

When the valve shaft 110 is detected not to rotate, comparing the timing duration with a second set duration, and if the timing duration is less than the second set duration, returning to detect whether the valve shaft 110 rotates, and repeating the above process; if the timing duration is longer than the second set duration, the controller 410 controls the strong fire solenoid valve 700 to close to change the gas stove fire to the weak fire.

When the gas stove is turned into small fire, the timer is not reset and continues to count time, and whether the valve shaft 110 rotates or not is judged by continuously detecting and judging whether the on-off state of the second microswitch 300 is changed or not; if the valve shaft 110 is rotating, the timing module is reset; if the valve shaft 110 is not rotating, the timing module continues to count and continuously detect the state of the valve shaft 110.

At this time, when it is detected that the valve shaft 110 is not rotated, the timing duration is compared with the first set duration, and if the timing duration is less than the first set duration, the process returns to detecting whether the valve shaft 110 is rotated, and the above process is repeated; if the timing duration is longer than the first set duration, the controller 410 controls the small ignition solenoid valve 710 to close the whole gas path, so that the gas stove is extinguished.

Through the above process, the valve control unit 400 can determine whether the valve shaft 110 rotates by acquiring the information of the on/off of the second micro switch 300 and the gear ring 200, and detect the length of time that the valve shaft 110 does not rotate. And determining whether to perform an operation of turning down the fire to the gas cooker by comparing the timed period with a second set period, and determining whether to perform an operation of turning off the fire to the gas cooker by comparing the timed period with the first set period.
