Description

Technical Field

[0001] The present application relates to the technical field of stoves, and in particular to a valve body and a stove using the valve body. Background Art

[0002] The performance of gas stoves is constantly changing and improving with the needs of different users. Considering that some users need to stir-fry when cooking, a stove with a one-button stir-fry function has emerged. When this function is activated, the stove's firepower will instantly increase to meet the user's needs for stir-frying ingredients.

[0003] Currently, there are two ways to start stir-frying. One is to control stir-frying by touch panel, and the other is to start stir-frying by the stopcock on the stove. For example, the Chinese utility model patent with application number CN202221820498.2 discloses a technology for starting stir-frying by the stopcock on the stove. When the stopcock is rotated to a certain angle, the micro switch can be triggered to start the stir-frying function.

[0004] The technology in the above patent replaces the high-fire state with the stir-fry state. On the one hand, the heat load state of the high-fire point is lost, and it is impossible to switch from the high-fire state to the stir-fry state. Summary of the Invention

[0005] The purpose of this application is to provide a valve body, which retains the heat load state of the high fire point, and mechanically limits the stove to be able to switch to the stir-fry state only in the high fire state, so that the firepower change is smoother and safer.

[0006] This application is achieved through the following technical solutions:

[0007] A valve body comprises a base, a rotary rod, a dial, a first switch, a second switch and a switch pressing piece;

[0008] The rotary rod is rotatably arranged on the base; the dial is arranged on the rotary rod, and the dial can rotate as the rotary rod rotates, and the dial is provided with a radially protruding dial edge;

[0010] The switch pressing piece is sleeved on the rotary rod and is located above the first switch. The switch pressing piece is configured to allow the rotary rod to push the switch pressing piece downward, but prohibit the rotary rod from driving the switch pressing piece to rotate.

[0011] When the rotary rod rotates, it can drive the dial edge to rotate to the second position so that the stove gradually changes from a low-fire state to a high-fire state. At the same time, the dial edge triggers the second switch action. At this time, the rotary rod is pressed down, and the rotary rod drives the switch pressing piece to be pressed down to trigger the first switch action, thereby starting the stir-fry function of the stove.

[0012] Preferably, the first switch and the second switch are both micro switches; a self-locking circuit is provided in the first switch so that when the first switch is triggered, the triggered switch state is maintained until the next triggering.

[0013] Preferably, when the rotary rod is in the pressed state or the non-pressed state, the prying edge in the second position can trigger the second switch.

[0014] Preferably, a line connecting the first position and the rotation axis of the rotating rod is recorded as a first line, a line connecting the second position and the rotation axis of the rotating rod is recorded as a second line, and an angle formed by the first line and the second line is 90 degrees.

[0015] Preferably, it further comprises a limiter fixed to the base, wherein the limiter is provided with a vertical guide portion, and the switch pressing piece can move up and down along the vertical guide portion and is restricted by the vertical guide portion to rotate around the rotating rod.

[0016] Preferably, the limiting member is an upper shell, the vertical guide portion is a notch opened in the upper shell, and the switch pressing piece is at least partially located in the notch.

[0017] Preferably, the rotary rod is provided with a retaining spring above the switch pressing piece, and the rotary rod is provided with a spring below the switch pressing piece.

[0018] Preferably, the dial includes a base plate and a surrounding edge, the surrounding edge is arc-shaped and partially surrounds the periphery of the base plate, and the dial edge is located on the surrounding edge.

[0019] Preferably, a third switch for ignition is further included, wherein the third switch is arranged at a third position on one side of the dial, and the third switch is triggered when the end of the surrounding edge reaches the third position.

[0020] Compared with the prior art, this application has the following advantages:

[0021] The valve body in the embodiment of the present application is rotated to the high fire position and then pressed to start stir-frying, which retains the heat load state of the high fire point. By setting a switch structure in series with the said dial edge, the stove is mechanically restricted from being able to and only being able to switch to the stir-fry state under the high fire state. The firepower change is smoother and safer, avoiding the occurrence of fire.

[0022] This embodiment also provides a stove including the valve body, which uses the valve body and thus has corresponding beneficial effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] like Figures 1 to 6 As shown, an embodiment of the present application provides a valve body for use on a cooker, which includes a base 1, a rotary rod 2, a dial 3, a first switch 4, a second switch 5 and a switch pressing piece 6.

[0032] Among them, the rotary rod 2 is rotatably provided on the base 1; the dial 3 is provided on the rotary rod 2, and the dial 3 can rotate with the rotation of the rotary rod 2, and the dial 3 is provided with a radially protruding dial edge 30; the first switch 4 is provided at a first position on one side of the dial 3; the second switch 5 is provided at a second position on one side of the dial 3, and the second switch 5 is provided in series with the first switch 4, that is, only when the second switch 5 and the first switch 4 are turned on at the same time can the circuit be connected; the switch pressing piece 6 is sleeved on the rotary rod 2 and located above the first switch 4, and the switch pressing piece 6 is configured to allow it to be pressed down by the rotary rod 2, but to prohibit it from being driven to rotate by the rotary rod 2.

[0033] When the rotary rod 2 rotates, it can drive the dial edge 30 of the dial 3 to rotate to the second position so that the stove gradually changes from a low-fire state to a high-fire state. At the same time, the dial edge 30 triggers the second switch 5 to operate. At this time, the rotary rod 2 is pressed down, and the rotary rod 2 drives the switch pressing piece 6 to press down to trigger the first switch 4 to operate, thereby starting the stir-fry function of the stove.

[0034] It should be noted that the stove is provided with a gas circuit that can increase the firepower to achieve stir-frying. The gas circuit is controlled by a solenoid valve. When the first switch 4 and the second switch 5 are both triggered to the passage state, the solenoid valve controls the stir-frying gas circuit to open, realizing the stir-frying function.

[0035] The valve body in the embodiment of the present application is rotated to the high fire position and then pressed to start stir-frying, thereby retaining the heat load state of the high fire point. By setting a switch structure in series with the said dial edge 30, the stove is mechanically restricted from being able to and only being able to switch to the stir-frying state under the high fire state, and the firepower change is smoother and safer, avoiding the occurrence of fire.

[0036] Preferably, the line connecting the first position and the axis of rotation of the rotary rod 2 is recorded as the first line, and the line connecting the second position and the axis of rotation of the rotary rod 2 is recorded as the second line, and the angle formed by the first line and the second line is 90 degrees. Its function is to make the stopcock on the rotary rod 2 in the first position be in the initial closed state, and reach the second position after rotating 90 degrees. It should be noted that in this embodiment, during the process of rotating the stopcock 90 degrees from the first position to the second position, the firepower is controlled to gradually change from low to high. When the stopcock is in the high fire state, that is, in the 90-degree position, pressing the stopcock starts stir-frying.

[0037] Furthermore, both the first and second switches 4, 5, are microswitches equipped with paddles. A self-locking circuit is incorporated into the first switch 4, ensuring that once activated, the first switch 4 remains in this state until the next activation. Furthermore, the paddle edge 30 in the second position can trigger the second switch 5, whether the rotary lever 2 is in the depressed or non-depressed state. This technical solution allows the first and second switches to remain in contact even after the rotary lever 2 is depressed and reactivated in the second position, maintaining the stir-frying state until the next press of the rotary lever 2, freeing the user's hands for other cooking operations.

[0038] The valve body also includes a limiter 7 fixed to the base 1, and a vertical guide portion 71 is provided on the limiter 7. The switch pressing piece 6 can move up and down along the vertical guide portion 71, and is restricted by the vertical guide portion 71 from rotating around the rotating rod 2. Through this technical solution, the switch pressing piece 6 is set to allow the rotating rod 2 to push down, but prohibit the rotating rod 2 from rotating.

[0039] More specifically, the stopper 7 is the upper shell, and the vertical guide portion 71 is a notch formed in the upper shell. The switch pressing piece 6 is at least partially located within the notch. Integrating the fiber structure into the upper shell allows the upper shell to function as both a protector and a stopper, saving parts and facilitating manufacturing and assembly.

[0040] In order to enable the rotary rod 2 to drive the switch pressing piece 6 to press down and automatically reset upward, the rotary rod 2 is provided with a retaining spring 21 above the switch pressing piece 6 and a spring 22 below the switch pressing piece 6.

[0041] In this embodiment, the dial 3 includes a base plate 31 and a peripheral edge 32. The peripheral edge 32 is arc-shaped and partially surrounds the periphery of the base plate 31. The paddle edge 30 is located on the peripheral edge 32. The raised paddle edge 30 can trigger the paddle action of the micro switch.

[0042] Furthermore, the valve body of this embodiment also includes a third switch 8 for ignition. The third switch 8 is located at a third position on one side of the dial 3. When the end of the edge 32 reaches the third position, the third switch 8 is activated. The third switch 8 can be activated by the end, without the need for a separate edge.

[0043] It should be understood that the terms "first", "second", etc. are used in this application to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information. In addition, the orientation or positional relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
