Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, and in particular to a gear adjustment device and a flow control valve. Background Art

[0002] With the development of society, people's pursuit of spiritual and sensory aspects has gradually been higher than that of the material surface, and the control requirements for gas stove products during the cooking process are also getting higher and higher. Currently, most gas stoves on the market use mechanical gear valves to control the size of the flame, but users often have the pain point of bending down and lowering their heads to check the flame condition to adjust the flame size during use.

[0003] To solve this problem, in the prior art, a gear adjuster is arranged inside the valve body of the mechanical gear valve to control the gear, and the gear feeling is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a gear adjustment device and a flow control valve to alleviate the technical problem that in the prior art, a gear adjuster is arranged inside the valve body of the mechanical gear valve to control the gear, and the gear feeling is poor.

[0005] In a first aspect, the present invention provides a gear adjustment device, including: a regulator housing and a rotating ring disposed inside the regulator housing and capable of rotating relative to the regulator housing, the rotating ring being capable of being inserted into the regulator housing or taken out from the regulator housing;

[0006] The regulator housing and the rotating ring have coaxial and through valve rod mounting holes;

[0007] The rotating ring is provided with a plurality of gear holes on its rotation trajectory;

[0008] The regulator housing is provided with an elastic member capable of elastic deformation, the elastic member has an elastic convex portion, and the elastic convex portion can be engaged with the gear hole and can be disengaged from the gear hole under the relative extrusion with the rotating ring.

[0009] Further, the regulator housing includes a regulator upper cover and a regulator base, and the regulator upper cover is snap-fitted with the regulator base.

[0010] Further, the elastic convex portion includes an elastic bottom plate portion and elastic side plate portions provided on opposite sides of the elastic bottom plate portion;

[0011] When the elastic convex portion and the rotating ring are mutually extruded, the elastic side plate portions can generate deformation displacement relative to the regulator upper cover.

[0012] Further, the elastic side plate portions are slidably connected to the regulator upper cover.

[0013] Further, a first sliding groove and a second sliding groove are provided on the upper cover of the regulator.

[0014] The elastic side plate parts on both sides are respectively in sliding fit with the first sliding groove and the second sliding groove, and the elastic bottom plate part is located between the first sliding groove and the second sliding groove.

[0015] Further, the distance between the elastic side plate parts on both sides gradually increases in the direction away from the elastic bottom plate part.

[0016] Further, the connection part between the elastic bottom plate part and the elastic side plate part is connected by an arc transition.

[0017] Further, the elastic member adopts a "Ji"-shaped elastic structure provided integrally.

[0018] Further, the valve rod mounting hole corresponding to the rotating ring is a special-shaped hole;

[0019] The valve rod mounting hole corresponding to the regulator housing is a circular hole.

[0020] Further, a connecting seat extends radially outward along the edge of the regulator base, and a connecting hole is provided on the connecting seat;

[0021] Alternatively, the regulator base is provided with a snap connection structure.

[0022] Beneficial effects:

[0023] The gear shifting device provided by the present invention includes a regulator housing and a rotating ring. The rotating ring can be inserted into or taken out of the regulator housing to complete the disassembly and assembly of the rotating ring in the regulator housing. Since the regulator housing and the rotating ring have coaxial and through valve rod mounting holes, therefore, in specific use, the valve rod of the flow control valve for controlling the flow rate of the valve body can be inserted into the valve rod mounting hole for installation. The rotating ring can be driven to rotate relative to the regulator housing through the valve rod. During the rotation of the rotating ring, since a plurality of gear holes are provided on the rotation trajectory of the rotating ring, and the regulator housing is provided with an elastic member capable of elastic deformation, and the elastic member has an elastic convex part, therefore, when the gear hole of the rotating ring rotates to directly below the elastic convex part of the elastic member, the elastic convex part can be snapped into the gear hole. Continuing to rotate the rotating ring, under the action of the elastic deformation of the elastic member, the elastic convex part can be disengaged from the gear hole, so as to realize the change of gears on the rotation trajectory of the rotating ring.

[0024] It can be seen that the gear shifting device realizes the change between gears through the cooperation of the elastic member and the gear holes. When the elastic convex part of the elastic member snaps into or disengages from the gear hole, a jamming or vibration feeling can be generated, so that it has an obvious gear feeling.

[0025] In a second aspect, the present invention provides a flow control valve, comprising: the gear shifting adjustment device according to any one of the foregoing embodiments.

[0026] Beneficial effects:

[0027] The flow control valve provided by the present invention includes the aforementioned gear shifting adjustment device. Thus, the technical advantages and effects that the flow control valve can achieve also include the technical advantages and effects that the gear shifting adjustment device can achieve, which will not be elaborated herein.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0049] Referring to Figures 1 to 3 , the present invention provides a gear shifting device, which includes a regulator housing 100 and a rotating ring 200 disposed inside the regulator housing 100 and capable of rotating relative to the regulator housing 100. The rotating ring 200 can be inserted into the regulator housing 100 or taken out from the regulator housing 100; the regulator housing 100 and the rotating ring 200 have coaxial and through valve rod mounting holes 300; the rotating ring 200 is provided with a plurality of gear holes 210 on its rotation trajectory; the regulator housing 100 is provided with an elastic member 400 capable of elastic deformation. The elastic member 400 has an elastic boss portion, and the elastic boss portion can be snapped into the gear hole 210 and can be disengaged from the gear hole 210 under the relative extrusion action with the rotating ring 200.

[0050] For the gear shifting device provided in this embodiment, the rotating ring 200 can be inserted into the regulator housing 100 or taken out from the regulator housing 100, and the disassembly and assembly of the rotating ring 200 in the regulator housing 100 can be completed. Since the regulator housing 100 and the rotating ring 200 have coaxial and through valve rod mounting holes 300, therefore, in specific use, the valve rod of the flow control valve for controlling the flow rate of the valve body can be inserted into the valve rod mounting hole 300 for installation, and the rotating ring 200 can be driven to rotate relative to the regulator housing 100 through the valve rod. During the rotation of the rotating ring 200, since the rotating ring 200 is provided with a plurality of gear holes 210 on its rotation trajectory and the regulator housing 100 is provided with an elastic member 400 capable of elastic deformation, and the elastic member 400 has an elastic boss portion, therefore, when the gear hole 210 of the rotating ring 200 rotates to directly below the elastic boss portion of the elastic member 400, the elastic boss portion can be snapped into the gear hole 210. Continuing to rotate the rotating ring 200, under the acting force of the elastic deformation of the elastic member 400, the elastic boss portion can be disengaged from the gear hole 210, so as to realize the change of gears on the rotation trajectory of the rotating ring 200.

[0051] It can be seen that the gear shifting device realizes the shifting between gears through the cooperation of the elastic member 400 and the gear holes 210. When the elastic boss portion of the elastic member 400 is engaged with or disengaged from the gear holes 210, a jamming or vibration feeling can be generated to make it have an obvious gear feeling.

[0052] Specifically, the elastic boss portion of the elastic member 400 is located directly above the rotation trajectory of the rotating ring 200, so that when the rotating ring 200 rotates, the gear hole 210 can rotate to a position corresponding to the elastic boss portion of the elastic member 400.

[0053] In this embodiment, two groups of elastic members 400 are provided, and the two elastic members 400 are arranged oppositely at 180°. Such an arrangement can make the force on the rotating ring 200 more stable when it contacts the elastic member 400, and can relatively improve the gear feeling.

[0054] In other embodiments, the elastic member 400 can also be provided in three or four groups. When the elastic member 400 is provided in more than two groups, the multiple groups are evenly arranged.

[0055] Refer to Figure 1 , the regulator housing 100 includes a regulator upper cover 110 and a regulator base 120. The regulator upper cover 110 and the regulator base 120 are snap-connected to facilitate the disassembly and assembly between the two; wherein, a snap is provided on either of the two, and a card slot for cooperating with the snap is provided on the other.

[0056] Furthermore, refer to Figure 4 and Figure 5 , the elastic boss portion includes an elastic bottom plate portion 410 and elastic side plate portions 420 provided on opposite sides of the elastic bottom plate portion 410; when the elastic bottom plate portion 410 of the elastic boss portion and the rotating ring 200 are mutually extruded, the elastic side plate portions 420 can generate a deformation displacement relative to the regulator upper cover 110.

[0057] Briefly speaking, in specific use, the valve stem rotates to drive the rotating ring 200 to rotate. When the elastic bottom plate portion 410 contacts the surface of the rotating ring 200, the elastic member 400 is compressed. When the gear hole 210 on the rotating ring 200 rotates to the lower part of the corresponding elastic member 400, the elastic member 400 restores its elasticity and collides with the gear hole 210, thereby generating a gear feeling.

[0058] In this embodiment, the elastic side plate portions 420 are slidably connected to the regulator upper cover 110.

[0059] Specifically, please continue to refer to Figure 5The regulator upper cover 110 is provided with a first slide groove 111 and a second slide groove 112; the elastic side plate portions 420 on both sides are respectively slidably matched with the first slide groove 111 and the second slide groove 112, and the elastic bottom plate portion 410 is located between the first slide groove 111 and the second slide groove 112.

[0060] Please refer again Figure 5 The distance between the elastic side plates 420 on both sides is gradually increased in the direction away from the elastic bottom plate 410. Such a configuration can relatively increase the overall deformation capacity of the elastic member 400, making the gear shift smoother.

[0061] The connection between the elastic bottom plate portion 410 and the elastic side plate portion 420 is connected by an arc transition to further increase the overall deformation capacity of the elastic member 400 .

[0062] In an optional embodiment, the elastic member 400 adopts an integrally arranged “J”-shaped elastic structure.

[0063] Based on the above embodiments, Figure 3 The valve stem mounting hole 300 corresponding to the rotating circle 200 is a special-shaped hole 211; the valve stem mounting holes 300 corresponding to the regulator cover 110 and the regulator base 120 are both round holes. With such an arrangement, after the gear adjustment device is installed on the valve stem of the flow control valve, the rotation of the valve stem can drive the rotating circle 200 to rotate.

[0064] Reference Figure 6 The edge of the regulator base 120 is radially extended outward to form a connecting seat 121, and the connecting seat 121 is provided with a connecting hole 1211. The regulator base 120 can be installed on the valve body of the flow control valve through fasteners.

[0065] Alternatively, a snap-fit ​​connection structure is provided on the side of the regulator base 120 facing away from the rotating circle 200, and the regulator base 120 can be snap-fitted onto the valve body of the flow control valve through the snap-fit ​​connection structure.

[0066] Refer to 1 to Figure 7 The present embodiment further provides a flow control valve, which includes the aforementioned gear adjustment device. The flow control valve provided in the present embodiment includes the aforementioned gear adjustment device, and thus, the technical advantages and effects that can be achieved by the flow control valve also include the technical advantages and effects that can be achieved by the gear adjustment device, which will not be repeated here.

[0067] Specifically, the flow control valve also includes a valve body, which includes a valve stem 500. The regulator housing 100 and the rotating ring 200 are both mounted on the valve stem 500 through the valve stem mounting hole 300, wherein the rotating ring 200 is fixedly mounted on the valve stem 500 to rotate with the valve stem 500.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
