[0072] The utility model will be described below in a preferred embodiment, and in combination with the drawings more clearly and completely.

[0073] As Figures 1-11 shown, the embodiment provides a stove, the stove includes panel 4 and gas valve 1, and the gas valve 1 includes valve stem 11 and knob 2, and the gas valve 1 further includes elastic connection structure 3, and the elastic connection structure 3 is arranged between valve stem 11 and knob 2, and knob 2 is connected to valve stem 11 through elastic connection structure 3. Figure 2 And Figure 4 As shown, the elastic connection structure 3 has elasticity along the axial direction of valve stem 11, and when knob 2 is pressed along the axial direction of valve stem 11 towards the elastic connection structure 3, the elastic connection structure 3 can switch between the first state and the second state along the axial direction of valve stem 11. Figure 2 As shown, when the elastic connection structure 3 is in the first state, the top surface 21 of knob 2 is higher than the upper surface of panel 4, and as Figure 4 shown, when the elastic connection structure 3 is in the second state, the top surface 21 of knob 2 is flush with the upper surface of panel 4. By setting the elastic connection structure 3, knob 2 is switched between extending out of panel 4 and being stored in panel 4 in the manner of pressing knob 2, so that knob 2 can extend out of panel 4 to ignite knob 2, and can also be stored in panel 4, which is convenient for cleaning and more beautiful. The position switching is realized in the manner of pressing knob 2, which conforms to the user's operation habit.

[0074] In the embodiment, the top surface 21 of knob 2 refers to the end surface of knob 2 away from the gas valve 1 along the axial direction of valve stem 11, and similarly, the upper surface of panel 4 refers to the surface of panel 4 away from the gas valve 1 along the axial direction of valve stem 11. In simple terms, the top surface 21 of knob 2 refers to the end surface pressed by the user when pressing knob 2, and the upper surface of panel 4 refers to the surface of panel 4 visible to the user.

[0075] In particular, in the embodiment, asFigure 1 、 Figure 2 and Figure 3 When the elastic connection structure 3 is in the first state, the lower part 22 of the knob 2 is located inside the panel 4, that is, when the knob 2 is popped out, the lower part 22 of the knob 2 is still hidden inside the panel 4. Compared with the scheme that the lower part 22 of the knob 2 is flush with the panel 4 when the elastic connection structure 3 is in the first state, the scheme that the lower part 22 of the knob 2 is located inside the panel 4 when the elastic connection structure 3 is in the first state in the embodiment can avoid the situation that the knob 2 cannot be accommodated due to the distortion of the knob 2 when the pressure for pressing the knob 2 is not parallel to the axial direction of the valve rod 11. At the same time, compared with the scheme that the lower part 22 of the knob 2 is arranged to be about 3 mm away from the panel 4 outside the panel 4 in the prior art, the scheme that the lower part 22 of the knob 2 is located inside the panel 4 when the elastic connection structure 3 is in the first state in the embodiment can further avoid the hidden dirt between the knob 2 and the panel 4 on the basis of arranging the knob 2 to be poppable and accommodable.

[0076] Of course, in other embodiments, it is also possible to arrange the knob 2 to be flush with or higher than the upper surface of the panel 4 when the elastic connection structure 3 is in the first position.

[0077] In the embodiment, as shown in Figure 4 and Figure 5 When the elastic connection structure 3 is in the second state, the upper surface of the knob 2 is flush with the upper surface of the panel 4. When the elastic connection structure 3 is in the second state, by arranging the knob 2 to be flush with the upper surface of the panel 4, the connection between the knob 2 and the panel 4 is not easy to hide dirt.

[0078] Of course, in other embodiments, it is also possible that the upper surface of the knob 2 is located inside the panel 4 when the elastic connection structure 3 is in the second state, which is also convenient for cleaning.

[0079] At the same time, in the embodiment, as shown in Figure 1 The upper surface of the panel 4 has a through hole 401 penetrating the panel 4 along the axial direction of the valve rod 11, the knob 2 is arranged in the through hole 401, and the inner diameter of the through hole 401 is equal to the outer diameter of the knob 2. By arranging the inner diameter of the through hole 401 to be equal to the outer diameter of the knob 2, the knob 2 occupies the volume of the through hole 401, and the through hole 401 is not easy to hide dirt.

[0080] In the embodiment, as shown in Figure 3 , Figure 5 and Figure 6As shown, the gas valve 1 further comprises a valve rod sleeve 12 sleeved on the outer circumferential side of the valve rod 11, the elastic connection structure 3 is connected with the valve rod sleeve 12, the valve rod sleeve 12 is provided with a first limiting protrusion 121 protruding outward along the radial direction of the valve rod sleeve 12 at one end of the valve rod sleeve 12 close to the valve body 13 of the stove, and the valve body 13 is provided with a second limiting protrusion 131 protruding along the axial direction of the valve rod 11 towards the valve rod 11. When the knob 2 is at the initial angle, the first limiting protrusion 121 abuts against the second limiting protrusion 131 along the axial direction of the valve rod 11, and the pressing stroke of the knob 2 is smaller than the pressing stroke of the knob 2 when the stove is ignited. When the knob 2 is not at the initial angle, the first limiting protrusion and the second limiting protrusion are arranged in a circumferential direction of the valve rod 11, and the pressing stroke of the knob 2 is equal to the pressing stroke of the knob 2 when the stove is ignited. By arranging the first limiting protrusion 121 and the second limiting protrusion 131, when the knob 2 is received at the initial angle, the valve of the valve body 13 is prevented from being opened by mistake.

[0081] Specifically, when the knob 2 is at the initial angle, the first limiting protrusion 121 abuts against the second limiting protrusion 131 along the axial direction of the valve rod 11, and the pressing stroke of the knob 2 is smaller than the pressing stroke of the knob 2 when the stove is ignited. At this time, pressing the knob 2 can only achieve the receiving of the knob 2. Due to the limitation of the first limiting protrusion 121 and the second limiting protrusion 131, the pressing stroke of the knob 2 cannot reach the pressing stroke required for ignition, thereby avoiding the valve from being opened by mistake at the initial angle. When the knob 2 is not at the initial angle, the first limiting protrusion 121 and the second limiting protrusion 131 are arranged in a circumferential direction of the valve rod 11, and there is no limitation of the first limiting protrusion 121 and the second limiting protrusion 131, and the pressing stroke of the knob 2 can reach the pressing stroke of the knob 2 required for ignition when the stove is ignited, thereby achieving ignition when the knob 2 is not at the initial angle, and the knob 2 can be rotated to adjust the fire size. Compared with the scheme of setting the pressing stroke to be greater than the pressing stroke of the knob 2 when the stove is ignited, by setting the pressing stroke of the knob 2 when the knob 2 is not at the initial angle to be exactly equal to the pressing stroke of the knob 2 required for ignition, reasonable limiting is achieved, and the stove is prevented from being damaged due to the user pressing the knob 2 too hard.

[0082] Of course, in other embodiments, the pressing stroke of the knob 2 when the knob 2 is not at the initial angle can also be greater than the pressing stroke of the knob 2 when the stove is ignited, but at this time the user needs to control the pressing force well to prevent the stove from being damaged due to the pressing force being too large.

[0083] Specifically in the embodiment, as shown in Figure 2 and Figure 4 the second limiting protrusion 131 is located directly below the valve rod 11. By arranging the second limiting protrusion 131 directly below the valve rod 11, the positioning and alignment of the first limiting protrusion 121 and the second limiting protrusion 131 are facilitated.

[0084] Of course, in other embodiments, the second limiting protrusion 131 can also be arranged in any direction, and it is more convenient to position it directly above or on the left and right sides of the valve rod 11 compared to other directions, which will not be described here.

[0085] In the present embodiment, as shown in Figure 3 and Figure 5 , the gas valve 1 further comprises a first elastic member 14, which is located between the valve rod 11 and the valve body 13 of the gas valve 1, and is used for ignition rebound. The elastic coefficient of the first elastic member 14 is smaller than that of the elastic connection structure 3. The first elastic member 14 in the present embodiment is a coil spring 34. By setting the elastic coefficient of the first elastic member 14 to be smaller than that of the elastic connection structure 3, when the knob 2 is not at the initial angle, pressing the knob 2 first realizes ignition, and further pressing the knob 2 realizes storage.

[0086] That is, when the pressing force is small, the elastic connection structure 3 will not be compressed or the compression amount will be small, but the first elastic member 14 in the gas valve 1 has already started to be pressed to open the valve of the gas valve 1, thereby achieving the purpose of ignition. Only by increasing the pressing force can the elastic connection structure 3 switch state, thereby storing the knob 2.

[0087] In the present embodiment, as shown in Figure 3 , Figure 5 and Figure 6 , the elastic connection structure 3 comprises a coil spring 34, a sliding limiting sleeve 33, a top rod 32 and a guide sleeve 31. The coil spring 34 is sleeved on the outer circumferential side of the valve rod 11. The coil spring 34, the sliding limiting sleeve 33 and the top rod 32 are coaxially arranged and sequentially arranged, that is, along the direction of the pressure that the knob 2 receives when the button is pressed, the top rod 32, the sliding limiting sleeve 33 and the coil spring 34 are sequentially arranged. At the same time, the guide sleeve 31 is connected with the valve rod sleeve 12 through a screw. The coil spring 34 abuts against the sliding limiting sleeve 33, and the guide sleeve 31 is sleeved on the outer circumferential side of the sliding limiting sleeve 33 and the top rod 32. As shown in Figure 7 and Figure 8 , the inner circumferential side of the guide sleeve 31 has first protrusions 311 arranged at intervals, the first protrusions 311 extend along the axial direction of the valve rod 11, and first grooves 313 are formed between adjacent first protrusions 311. The end of the first protrusion 311 close to the coil spring 34 has a first sawtooth 312, and the first sawtooth 312 is a double-tooth structure. As shown in Figure 9 , the outer circumferential side of the top rod 32 has a second protrusion 321, which extends along the axial direction of the valve rod 11. The first end of the top rod 32 close to the coil spring 34 has a second sawtooth 322, which is a single-tooth structure, and the second protrusion 321 is embedded in the first groove 313, as shown in Figure 3 and Figure 5As shown, the size of the second protrusions 321 is smaller than the first grooves 313 along the axial direction of the valve stem 11. As shown, Figure 10 and Figure 11 As shown, the outer circumferential side of the sliding limiting sleeve 33 is provided with the first protrusions 311 at intervals, the third protrusions 331 extend along the axial direction of the valve stem 11, the third protrusions 331 have the third serrations 332 at one end close to the top rod 32, the third serrations 332 are single-tooth structures, and the third protrusions 331 can be embedded in the first grooves 313 and slide along the axial direction of the valve stem 11. When the top rod 32 is subjected to the pressure along the axial direction of the valve stem 11 close to the sliding limiting sleeve 33, the second serrations 322 push the third serrations 332 to move along the axial direction of the valve stem 11 close to the coil spring 34, and the third serrations 332 slide into the first grooves 313 and abut against the second protrusions 321 located in the first grooves 313 under the elastic force of the coil spring 34 and the guiding effect of the first serrations 312, so that the top surface of the knob 2 is flush with or lower than the upper surface of the panel 4, or the third serrations 332 slide into the gaps between the first serrations 312 and abut against the first serrations 312, so that the top surface of the knob 2 is higher than the upper surface of the panel 4. Through the cooperation of the top rod 32, the sliding limiting sleeve 33 and the guide sleeve 31, the state switching of the elastic connection structure 3 is realized.

[0088] Of course, in other embodiments, other elastic connection structures 3 in the prior art can also be used to meet the requirement that the elastic connection structure 3 extends along the axial direction of the valve stem 11 to switch between the first state and the second state, which will not be described here.

[0089] Specifically, in the present embodiment, as shown, Figures 7-11 the number of the first protrusions 311 is four, and correspondingly, the number of the first grooves 313 and the third protrusions 331 is also four, and the number of the second protrusions 321 is eight.

[0090] Meanwhile, in the present embodiment, as shown, Figure 8 the first serrations 312 have serration one 3121 and serration two 3122, and the sum of the tooth width of the serration one 3121 and the width of the first grooves 313 is equal to the tooth width of the serration two 3122. By setting the width relationship of the serration one 3121 and the serration two 3122 in the first serrations 312 as: the sum of the tooth width of the serration one 3121 and the width of the first grooves 313 is equal to the tooth width of the serration two 3122, the angle turned by the sliding limiting sleeve 33 is equal each time the elastic connection structure 3 switches states.

[0091] Specifically, in the process of switching the elastic connection structure 3 from the first state to the second state, the third convex strip 331 moves along the circumference by a distance equal to the sum of the tooth width of the sawtooth one 3121 and the width of the first groove 313; in the process of switching the elastic connection structure 3 from the second state to the first state, the third convex strip 331 moves along the circumference by a distance equal to the tooth width of the sawtooth two 3122.

[0092] In the embodiment, the top rod 32 is inserted between the knob 2, the knob 2 has an insertion hole in the interior, the cross-sectional shape of the insertion hole is not circular, the top rod 32 is inserted into the insertion hole and is fitted with the inner circumferential side of the insertion hole, and the valve rod 11 and the valve rod sleeve 12 are also inserted in the same way to realize that when the knob 2 is screwed, the knob 2 drives the top rod 32, the guide sleeve 31, the valve rod sleeve 12 and the valve rod 11 and other structures to rotate synchronously.

[0093] Of course, in other embodiments, the knob 2 and the top rod 32 can also be integrally formed. By integrally forming the top rod 32 and the knob 2, the reliability of the connection between the top rod 32 and the knob 2 is improved.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
