The gas cooker 100 is a common kitchen utensil, and is widely used in life due to its advantages of high efficiency and low cost, and becomes a necessary household utensil. And the gas cooker 100 can adjust the size of the flame according to the cooking of the user, which is very convenient. The knob 3 for adjusting the size of the flame is generally a T-shaped knob 3 or a cylindrical knob 3 with a plane top surface. The T-shaped knob 3 is easy to operate, but a part of the T-shaped knob is highlighted, so that the visual appearance of the knob 3 is poor. Although the cylindrical knob 3 has higher integrity and higher surface consistency, when oil drops drip on the outer surface of the knob 3, the surface of the cylindrical knob 3 is easy to slip, which is not beneficial to the operation of a user. On this basis, the utility model provides a cooking utensils 100, as shown in fig. 1, this cooking utensils 100 can include combustor 1, valve rod 2 and knob 3. Wherein, one end of a valve rod 2 in the knob 3 is connected with the burner 1, and the other end is connected with the knob 3 of the cover of the cooker 100.

In this case, as shown in fig. 1, the user can control the rotation of the valve rod 2 by the rotation of the knob 3, and since the valve rod 2 is connected to the burner 1, the knob 3 can indirectly control the flame size of the burner 1, thereby satisfying the user's demand. When the flame needs to be adjusted to be large, the flame can rotate clockwise or anticlockwise, and when the flame needs to be adjusted to be small, the flame rotates in the opposite direction. The utility model discloses clockwise and anticlockwise when adjusting the flame do not do the injecion, can satisfy the adjustment flame size can.

The above mentioned knob 3 structure is exemplified below, for example, in some embodiments of the present application, as shown in fig. 2, it can be seen that the knob 3 may include a knob cap 32 and a housing 33. Wherein the button cap 32 protrudes above the outer cover 33. As shown in fig. 3, the knob 3 may further include an inner cover 31, and the inner cover 31 may include an inner cover body 311 and a first boss 312 connected to the inner cover body 311. The outer cover 33 covers the outer cover 31, and the inner cover body 311 is connected to the above-mentioned valve rod 2. The button cap 32 has a mounting groove 321, and a portion of the first boss 312 is located in the mounting groove 321.

In this case, as shown in fig. 3, the button cap 32 may move up and down along the first boss 312, i.e., in the Y-axis direction, so that when a user applies an external force downward to the button cap 32, the button cap 32 may move in the Y-axis direction toward the inner cover 31, so that the button cap 32 may enter the outer cover 33, so that the button cap 32 is not exposed to the upper surface of the outer cover 33, so that the knob 3 may look integral and the outer aesthetic sense of the knob 3 may be improved. Along with the progress of cooking, the oil smoke in the pot on combustor 1 can spill to make the dustcoat 33 of knob 3 drop oil on every side, at this moment, if rotatory dustcoat 33 produces the skid easily, is unfavorable for the user to carry out the control to the flame. The user can apply an external force to the button cap 32 to eject the button cap 32 from the housing 33, and the cross section of the button cap 32 in the plane X may be polygonal, so as to facilitate the user to apply a rotational external force to the button cap 32, thereby rotating the housing 33 or the valve stem 2.

As shown in fig. 4, for 3 bottom schematics of knob, knob 3 passes through the notch in the middle and 2 joints of valve rod to 3 rotations of knob can drive valve rod 2 and rotate, control flame size.

To prevent the button cap 32 from being ejected from the housing 33, in some embodiments of the present application, the knob 3 may further include a stopper 322, as shown in fig. 5, connected to an outer surface of the button cap 32. As shown in FIG. 6, it can be seen that the stop portions 322 can be disposed on both sides of the button cap 32. Fig. 7 is a schematic view of the outer cover 33, and fig. 8 is a cross-sectional view taken along the direction BB in fig. 7, in which the outer cover 33 has a receiving groove 331, and an opening 3311 is opened at the bottom of the receiving groove 331. The inner cover 31 is disposed in the receiving groove 331 and connected to the outer cover 33. Wherein the button cap 32 is installed at the opening 3311. In fig. 8, the knob cap 32 is pressed into the receiving groove 331, and the limiting portion 322 is used to abut against the bottom wall of the receiving groove 331 when the knob cap 32 extends out of the opening 3311.

In this case, as shown in fig. 8, when the knob cap 32 moves at the opening 3311 in the Y direction, the stopper 322 may abut on the bottom wall of the accommodation groove 331, and as the stopper 322 is connected to the outer surface of the knob cap 32, it is possible to prevent the knob cap 32 from being popped up at the opening 3311, thereby forming a stopper effect on the knob cap 32.

When the user releases the button cap 32 in the Y direction to remove the external force, an assisting force is required to make a portion of the button cap 32 pop out from the opening 3311, in which case, in some embodiments of the present application, the knob 3 may further include a spring 34 as shown in fig. 9, and the spring 34 is disposed between the first boss 312 and the bottom of the mounting groove 321 as shown in fig. 10. The spring 34 of the present invention is used to provide a force assist in the Y direction for the button cap 32, thereby allowing the button cap 32 to pop out of the outer cover 33 more quickly.

Thus, as shown in fig. 10, when a user applies a downward force to the button cap 32 in the Y direction, the button cap 32 is pressed downward, so that the spring 34 between the first boss 312 and the mounting groove 321 is compressed, and the spring 34 starts to accumulate force. When the user removes the external force applied to the button cap 32, the spring 34 starts to restore its shape, so that the spring 34 exerts an upward external force on the button cap 32, so that a portion of the button cap 32 can be ejected out of the outer cover 33, thereby facilitating the user's manipulation of the button cap 32.

In order to prevent the spring 34 from being trapped and affecting the movement of the knob cap 32, in some embodiments of the present invention, the knob 3 may further include at least one second protrusion 323 as shown in fig. 10, the at least one second protrusion 323 is disposed in the mounting groove 321 and connected to the bottom of the mounting groove 321, and a first fixing groove 3231 as shown in fig. 11 is formed at an end of the second protrusion 323 away from the bottom of the mounting groove 321. As shown in fig. 12, a second fixing groove 3121 is opened at one side of the first protruding platform 312 close to the spring 34. One end of the spring 34 is positioned in the first fixing groove 3231 and the other end is positioned in the second fixing groove 3121.

In this case, when the button cap 32 moves up and down in the Y direction, the first fixing groove 3231 and the second fixing groove 3121 may fix both upper and lower ends of the spring 34, thereby preventing the position of the spring 34 from being changed, so that the spring 34 may be stably deformed between the second boss 323 and the first boss 312.

To move the button cap 32 up and down in the Y direction, it can be fixed when the button cap 32 is pressed into the housing 33, the spring 34 is prevented from being deformed again, and it can be fixed when the button cap 32 is extended out of the housing 33. In some embodiments of the present application, as shown in fig. 13, the sliding groove 3122 is formed in the first boss 312, and as shown in fig. 14, a first groove 31221 is formed in a side of the first boss 312 away from the inner cover body 311, a second groove 31222 is formed in a side of the first boss 312 close to the guide groove 324, and the second groove 31222 is communicated with the first groove 31221 to form the sliding groove 3122. The inner side of the groove wall of the mounting groove 321 opposite to the sliding groove 3122 is provided with a guide groove 324 in fig. 16.

As shown in fig. 15, the sliding groove 3122 is opened on the first protruding platform 312, the knob 3 may further include a guiding element 35, one end of the guiding element 35 is located in the sliding groove 3122, and the other end is located in the guiding groove 324. The guide 35 is configured to move within the guide groove 324 and the slide groove 3122 in the first direction (X direction) and move within the guide groove 324 in the second direction (Y direction) when an external force is applied to the button cap 32, so that the button cap 32 protrudes or protrudes into the housing 33. The second direction is the same as the extension direction of the valve stem 2 (not shown in fig. 15).

In this case, the valve rod 2 of the cooker 100 is connected to the inner cover body 311, and thus, the valve rod 2 can be driven to rotate by the rotation of the inner cover body 311 to control the size of the flame. Set up the first boss 312 that links to each other on the inner cover body 311, a part of first boss 312 is located the mounting groove 321 of button cap 32, and the user can drive first boss 312 rotatory through the rotation of button cap 32 to make the inner cover body 311 rotatory reach the effect of control flame size. One end of the guide 35 is positioned in the sliding groove 3122 of the first boss 312 and the other end is positioned in the guide groove 324 in the mounting groove 321, and the guide 35 can perform a movement in the first and second directions in the first guide groove 324, so that the knob cap 32 is in a process of ascending or descending when the guide 35 moves in the second direction since the second direction is the same as the extending direction of the valve stem 2. The guide 35 effects switching of the up and down movement in the second direction by the movement in the first direction. Further, the spring 34 is disposed between the first boss 312 and the bottom of the mounting groove 321, in which case, when a user applies a downward force to the button cap 32 in the second direction, the spring 34 is compressed, the button cap 32 moves downward, and the button cap 32 can be inserted into the housing 33, thereby making the appearance of the knob 3 more uniform overall. When the user unclamped button cap 32, spring 34 began to extend in the second direction to recovering deformation state, and this moment, button cap 32 is by jack-up on the second direction to button cap 32 stretches out dustcoat 33, makes the user carry out the rotation control flame size through button cap 32, thereby can solve the problem of the inconvenient operation of the dustcoat 33 drippage greasy dirt of button cap 32.

Specifically, the first direction and the second direction are perpendicular. So that one end of the guide 35 can be slid in the second direction to enable the button cap 32 to be moved up and down. The direction of movement of the steering element in the second direction can be switched by the first direction.

Specifically, the above-mentioned guide groove 324 is exemplified below, for example, in some embodiments of the present application, as shown in fig. 17, the guide groove 324 may further include a first guide sub-groove 3241, a second guide sub-groove 3242, a third guide sub-groove 3243, and a fourth guide sub-groove 3244. Wherein the first guide sub-groove 3241 extends in the second direction (Y-direction). The second guide sub-groove 3242 is opposite to the first guide sub-groove 3241 and is disposed in parallel. The third guide sub-groove 3243 extends in the first direction (X direction) and communicates with the first guide sub-groove 3241 and the second guide sub-groove 3242, and the third guide sub-groove 3243 serves to guide the guide 35 to the first guide sub-groove 3241. The fourth guide sub-groove 3244 is disposed opposite to the third guide sub-groove 3243 and communicates with the first guide sub-groove 3241 and the second guide sub-groove 3242, and the fourth guide sub-groove 3244 serves to guide the guide 35 to the second guide sub-groove 3242.

One end of the guide 35 may move in a zigzag along the first, second, third and fourth guide sub-grooves 3241, 3242, 3243 and 3244 in the guide groove 324, and in some embodiments, one end of the guide 35 may rotate counterclockwise or clockwise in a zigzag. The other end of the guide 35 slides within the slide groove 3122.

In some embodiments of the present application, one end of the guide 35 may move clockwise or counterclockwise in the guide groove 324, wherein the guide groove 324 is arranged in a mirror image when rotating counterclockwise and when rotating clockwise. For example, in some embodiments of the present application, as shown in fig. 17, the third guide sub-groove 3243 may include a first groove wall 32431 and a second groove wall 32432 that are oppositely disposed. The first groove wall 32431 and the second groove wall 32432 are protruded in a direction away from the fourth guide sub-groove 3244, and the protruded position of the first groove wall 32431 is close to the first guide sub-groove 3241 with respect to the protruded position of the second groove wall 32432. The fourth guide sub-slot 3244 may include third and fourth slot walls 32441, 32442 that are oppositely disposed. The third groove wall 32441 is protruded in a direction to be close to the third guide sub-groove 3243, the fourth groove wall 32442 is partially protruded in a direction to be away from the third guide sub-groove 3243, and the fourth groove wall 32442 further has a portion protruded in a direction to be close to the third guide sub-groove 3243. The convex position of the third groove wall 32441 is adjacent to the second guide sub-groove 3242 relative to the convex position of the fourth groove wall 32442 adjacent to the third guide sub-groove 3243.

Thus, as shown in fig. 17, when one end of the guide 35 is at the protruding position on the first groove wall 32431, the knob cap 32 is exposed to the upper portion of the housing 33 (see fig. 3), and the protruding position on the first groove wall 32431 can limit the guide 35 to a certain extent. When a user applies downward pressure to the button cap 32, one end of the guide 35 slides into the first guide sub-groove 3241 along the slope of the second groove wall 32432, thereby moving downward in the second direction. When one end of the guide 35 is pressed to the depressed convex portion of the fourth groove wall 32442, the button cap 32 is released, and the guide 35 moves up along the third groove wall 32441 to a convex position due to the elastic force of the spring 34, thereby being caught by the member, at which time the button cap 32 is in the housing 33, and the top surface of the button cap 32 may be parallel to the top surface of the housing 33. The outer surface of the cover 33 is more aesthetically pleasing (see fig. 15). The button cap 32 is continuously pressed, and at this time, one end of the guide 35 moves to the bottom corner of the guide groove 324 along the slope of the fourth groove wall 32442. When the button cap 32 is released, the guide 35 slides upward along the second guide sub-groove 3242 (under the action of the return deformation of the spring 34), and the guide 35 finally falls down along the slope of the first groove wall 32431 to a convex position on the first groove wall 32431, thereby forming a loop.

The above-mentioned structure of the guide 35 is exemplified below, for example, in some embodiments of the present application, as shown in fig. 18, the guide 35 may include a roller 351 and a round cap 352, wherein the roller 351 has a first end and a second end opposite to the first end, and the first end is located in the guide groove 324 through the sliding groove 3122. The round cover 352 is vertically connected to the second end of the roller 351, the round cover 352 is disposed in the sliding groove 3122 and rolls along the sliding groove 3122 in a first direction, and the first end moves in the guide groove 324 in the first direction and a second direction.

Thus, when the dome 352 rolls in the first direction in the sliding groove 3122, the roller 351 can slide along the third guide sub-groove 3243 or the fourth guide sub-groove 3244, so that the guide 35 can be switched between the first direction and the second direction.

The above-mentioned structure of the sliding groove 3122 is exemplified below, for example, in some embodiments of the present application, in which, as shown in fig. 19, the first groove 31221 and the second groove 31222 extend in a first direction, a portion of the roller 351 is located in the second groove 31222, and the dome 352 is disposed in the first groove 31221 and rolls along the extending direction of the first groove 31221.

In this case, the dome 352 may roll in the first groove 31221, and the roller 351 may protrude into the guide groove 324 through the second groove 31222. When the dome 352 rolls in the first groove 31221, the roller 351 may slide in the second groove 31222, and the other end of the roller 351 may slide in the guide groove 324 (not shown in fig. 19).

To sum up, the present invention can realize the conversion between the first guiding sub-groove 3241 and the second guiding sub-groove 3242 by the rolling matching roller 351 of the round cover 352 of the guiding element 35 in the first groove 31221 moving in the third guiding sub-groove 3243 and the fourth guiding sub-groove 3244 of the guiding element 324, so as to achieve the effect of ascending or descending the button cap 32. The power source user applies an external force to cooperate with the elastic force of the spring 34. The utility model is not only simple in structure, installation convenient operation moreover.
