Description

Technical Field

[0001] The present application relates to the technical field of gas stove accessories, and more specifically to a gas stove shutter. Background Art

[0002] A gas stove is a kitchen appliance that uses natural gas or other gaseous fuel as a medium for open flame heating. When the gas stove is working, the gas fuel enters the stove from the air inlet pipe, flows to the burner after passing through the switch valve, and forms a flame after being ignited by the ignition device, which is used to heat the cooker placed on the pot support. The switch valve includes a valve stem and a closure, which is also called a valve core. The two ends of the valve stem are respectively connected to the closure and the knob. The closure has a number of flow holes. When the valve stem rotates a predetermined angle, it drives the closure to rotate a predetermined angle, and makes the flow holes face the corresponding gas outlet channel, so that the gas fuel flows to the burner.

[0003] The patent document (CN108869776A) discloses a gas stove switch valve, including a valve core, a valve stem, a valve cup and a plurality of air outlet pipes. The valve core is rotatably installed in the valve cup. The valve stem is connected to the valve core and drives the valve core to rotate. The valve core has a plurality of air guide holes. When the valve stem rotates and drives the valve core to rotate a predetermined angle, the air guide holes on the valve core are directly opposite to the inner wall of the air outlet pipe or the valve cup. When the air guide holes are directly opposite to the air outlet pipe, the gas fuel flows out from the air outlet pipe. When the air guide holes are directly opposite to the inner wall of the valve cup, the gas fuel is blocked because the outer wall of the valve core fits the inner wall of the valve cup. However, since the outer wall of the valve core fits the inner wall of the valve cup, after the valve core is used for a long time, the outer wall of the valve core or the inner wall of the valve cup is worn, and there is a gap between the outer wall of the valve core and the inner wall of the valve cup, so that the gas fuel can flow to any air outlet pipe along the gap, that is, leakage, and the size of the flame is difficult to control.

[0004] Therefore, there is a need to provide a gas stove closure that is leak-proof. Summary of the invention

[0032] Schematic gas stove with a shutoff,

[0033] refer to Figures 1 to 8 According to a preferred embodiment of the utility model, a gas stove shutter is rotatably mounted on an external valve cup 90 and includes a core body 10 and five anti-leakage components 20.

[0034] Specifically, Figure 2 As shown, the core body 10 has five air outlet holes 101 , an air inlet hole 102 and a hollow cavity 103 , and the hollow cavity 103 connects each of the air outlet holes 101 and the air inlet hole 102 .

[0035] In addition, if Figure 3As shown, each of the air outlet holes 101 is provided with an anti-leakage component 20, and each of the anti-leakage components 20 includes a deformable seal 201, and the deformable seal 201 is slidably arranged in the air outlet hole 101, and the two ends of the deformable seal 201 are respectively provided with a closing portion 2011 and an elastic deformable portion 2012, and the side wall of the closing portion 2011 is in contact with the hole wall of the air outlet hole 101, and the elastic deformable portion 2012 is close to the hole opening of the air outlet hole 101, and the deformable seal 201 has a through-going flow hole 2013.

[0036] It should be noted that the gas fuel flows into the hollow cavity 103 from the gas inlet 102, and flows to the external gas outlet pipeline 91 from the gas outlet 101; since the side wall of the closing portion 2011 is in contact with the hole wall of the gas outlet 101, the gas fuel placed in the hollow cavity 103 flows to the outside through the flow hole 2013. It should also be noted that the deformable seal 201 normally extends out of the hole opening of the gas outlet 101 by a predetermined distance, and when the deformable seal 201 is subjected to force, it can be retracted into the gas outlet 101 by a predetermined distance.

[0037] The gas stove closure is briefly described below: Assume that the outer wall of the core 10 is in contact with the inner wall of the outer valve cup 90. Figure 5 As shown in the figure, when the core 10 is rotated and the air outlet 101 is arranged in a staggered manner with the external air outlet pipeline 91, since the edge of the air outlet 101 is in contact with the inner wall of the external valve cup 90, there is no space for the deformable seal 201 to extend outward, and the deformable seal 201 is forced to retract into the air outlet 101. However, it should be emphasized that at this time, the elastic deformation portion 2012 of the deformable seal 201 is still in contact with the inner wall of the external valve cup 90, that is, at this time, the inner wall of the external valve cup 90 blocks the flow hole 2013, and the gas fuel cannot flow out from the flow hole 2013. In addition, as Figure 6 As shown, when the air outlet 101 is facing the external air outlet pipeline 91, since the external air outlet pipeline 91 provides a space for the deformable seal 201 to extend outward, the deformable seal 201 extends out of the orifice of the air outlet 101 by a predetermined distance, and the flow hole 2013 is not blocked at this time, the gas fuel can flow from the flow hole 2013 to the external air outlet pipeline 91.

[0038] Assume that after the gas switch valve has been used for a long time, there is a gap between the outer wall of the core 10 and the inner wall of the outer valve cup 90 due to wear. Figure 7As shown in FIG. 1 , when the gas outlet 101 and the external gas outlet pipeline 91 are arranged in a staggered manner, due to the gap between the outer wall of the core 10 and the inner wall of the external valve cup 90, the deformable seal 201 will partially retract into the gas outlet 101, but the end of the deformable seal 201 away from the hollow cavity 103, that is, the elastic deformation portion 2012 still extends out of the hole of the gas outlet 101 by a predetermined distance and fits with the inner wall of the external valve cup 90, and the flow hole 2013 is closed by the inner wall of the external valve cup 90 to achieve sealing of the gas fuel; and as shown in FIG. Figure 8 As shown, when the air outlet hole 101 is facing the external air outlet pipe 91, since the gas fuel flows into the external air outlet pipe 91 through the flow hole 2013, when the deformable seal 201 extends into and closes the inlet of the external air outlet pipe 91, and the flow hole 2013 is connected to the external air outlet pipe 91, the gas fuel can still flow smoothly to the external air outlet pipe 91.

[0039] Furthermore, in order to realize that the deformable seal 201 normally extends out of the hole edge of the air outlet 101 by a predetermined distance, and can be retracted into the air outlet 101 by a predetermined distance after being subjected to force, as Figure 3 and Figure 4 As shown, each of the anti-leakage components 20 includes an elastic member 202 , which is a spring. Two ends of the elastic member 202 are respectively connected to the deformable sealing member 201 and the core body 10 .

[0040] Furthermore, in order to realize the connection between the elastic member 202 and the core body 10, as Figure 1 and Figure 3 As shown, each of the air inlet holes 102 has an annular abutment portion 1021 on one side close to the hollow cavity 103 , and both ends of the elastic member 202 are fixedly connected to the annular abutment portion 1021 and the end surface of the closing portion 2011 , respectively.

[0041] Furthermore, in order to further improve the sealing performance between the sealing portion 2011 and the wall of the air outlet 101, as Figure 3 and Figure 4 As shown, each of the anti-leakage components 20 includes a sealing ring 203 , and the side wall of the closing portion 2011 has a first annular groove 20111 , and each of the first annular grooves 20111 is provided with a sealing ring 203 .

[0042] Furthermore, in order to improve lubrication and reduce wear between the sealing portion 2011 and the wall of the air outlet 101, as Figure 3 and Figure 4As shown, each of the anti-leakage components 20 includes a lubricating grease 204 , and the side wall of the closing portion 2011 has a second annular groove 20112 , and each of the second annular grooves 20112 is provided with the lubricating grease 204 .

[0043] Furthermore, in order to facilitate the deformation seal 201 to retract after being in contact with the inner wall of the outer valve cup 90 during the circumferential rotation of the core body 10, as shown in FIG. Figure 3 and Figure 4 As shown, there is a spherical portion 2014 between the sealing portion 2011 and the elastic deformation portion 2012 .

[0044] It should be noted that the closing portion 2011 and the spherical portion 2014 are both made of metal, the material of the elastic deformation portion 2012 is preferably rubber, the two ends of the elastic member 202 are respectively welded to the annular abutment portion 1021 and the closing portion 2011, and the elastic deformation portion 2012 is connected to the spherical portion 2014 by bonding.

[0045] Furthermore, in order to facilitate the connection between the core body 10 and the external valve stem, as Figure 1 and Figure 2 As shown, the core 10 has a clamping groove 104 at one end away from the air outlet 101. It should be noted that one end of the external valve stem extends into the clamping groove 104 and is interference fit with the core 10. When the external valve stem rotates, the core 10 rotates circumferentially.

[0046] Further, in the embodiments of the present application, Figure 1 and Figure 2 As shown, the core 10 includes a cylindrical portion 105 and a conical portion 106, the embedded groove 104 extends a predetermined distance from an end surface of the cylindrical portion 105 away from the conical portion 106 toward the conical portion 106, the air outlet 101 is located on the side of the conical portion 106, and the air inlet 102 is located on an end surface of the conical portion 106 away from the cylindrical portion 105.

[0047] It should be noted that, in the embodiment of the present application, the five air outlet holes 101 are respectively an inner ring high fire air guide hole, a first inner ring low fire air guide hole, a second inner ring low fire air guide hole, an outer ring high fire air guide hole, and an outer ring low fire air guide hole.

[0048] In addition, in order to improve the sealing performance between the top of the core 10 and the external valve cup 90, as shown in FIG. Figure 1 and Figure 2 As shown, a ring-shaped sealing groove 107 is provided at the connection between the cylindrical surface portion 105 and the conical surface portion 106 , and a sealing ring (not shown in the figure) is sleeved in the ring-shaped sealing groove 107 .

[0049] In summary, the gas stove closure according to the embodiment of the present application is explained, which provides the gas stove closure with advantages such as preventing gas leakage.
