[0040] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0041] Embodiment 1:

[0042] like Figure 1-Figure 5 As shown, the utility model discloses a damping type rotation adjustment assembly, comprising a mounting seat 2 and a rotating seat 1;

[0043] The rotating seat 1 is provided with a shift portion 3, wherein a plurality of blocking protrusions 32 are provided on the shift portion 3 along the circumferential direction, so that a shift slot 31 is formed between adjacent blocking protrusions 32, and each shift slot 31 is separated under the action of the blocking protrusions 32, and an elastic member 4 is provided on the mounting seat 2, and the elastic member 4 is clamped in any shift slot 31 to limit the relative rotation of the mounting seat 2 and the rotating seat 1;

[0044] In addition, when the mounting base 2 rotates relative to the rotating base 1, the elastic member 4 is elastically deformed by the inner wall of the gear slot 31, so that the elastic member 4 is disengaged from the current gear slot 31, and elastically resets after being located in the adjacent gear slot 31 and re-engages in the new gear slot 31, so that the rotating base 1 rotates relative to the mounting base 2 so that the elastic member 4 realizes damped rotation through elastic deformation in the process of the elastic member 4 passing from one side of the blocking protrusion 32 to the other side thereof.

[0045] Therefore, after the rotating seat 1 and the mounting seat 2 are respectively assembled on the regulating valve, the rotating seat 1 is controlled to rotate so that the elastic member 4 is matched in different gear slots 31. Since the elastic member 4 jumps from the current gear slot 31 to the adjacent gear slot 31, the elastic member 4 needs to be elastically deformed under the action of the blocking protrusion 32. The elastic deformation will hinder the rotation of the rotating seat 1, which is manifested as damped rotation in terms of tactile sense. In addition, when the elastic member 4 completely escapes from the current gear slot 31 and enters the adjacent gear slot 31, the elastic member 4 will automatically reset. Under the reset action, the elastic member 4 rebounds quickly and hits the inner wall of the gear slot 31 to make a "click" sound, so that the operator can judge the change of the flame by touch and hearing, and the increase and decrease of the flame between the gears are relatively constant, making the control more precise.

[0046] In other embodiments, the shift portion 3 is mounted on the mounting seat 2 , and the elastic member 4 is mounted on the rotating seat 1 .

[0047] Specifically, the elastic member 4 in this embodiment includes a snap-fitting portion 41 and mounting pins 42 located at both ends of the snap-fitting portion 41; wherein the snap-fitting portion 41 is used to cooperate with the gear slot 31 for limiting, and the mounting pins 42 are used to bend and deform when the snap-fitting portion 41 escapes from the gear slot 31.

[0048] Preferably, the snap-fitting portion 41 in this embodiment is U-shaped, V-shaped or arc-shaped. Specifically, the blocking protrusion 32 is semi-cylindrical, so that during the transition process, the snap-fitting portion 41 can be fitted on the arc-shaped outer wall of the blocking protrusion 32 under the action of the tip shrinkage or arc shrinkage of the snap-fitting portion 41 itself, and can be disengaged more smoothly.

[0049] Preferably, each mounting pin 42 in this embodiment is in the shape of a thin rod extending in a straight line, and the mounting pin 42 and the snap-fitting portion 41 are an integral piece. Specifically, each mounting pin 42 is formed on the snap-fitting portion 41 in a bending manner.

[0050] Therefore, the overall structure of the elastic member 4 is simpler, the processing is more convenient, and the production cost is lower.

[0051] In addition, a second mounting ring 21 is integrally formed on the side of the mounting seat 2 facing the rotating seat 1 in this embodiment, and a first mounting ring 11 is integrally formed on the side of the rotating seat 1 facing the mounting seat 2, and the second mounting ring 21 is sleeved on the outer periphery of the first mounting ring 11, so that with the cooperation of the first mounting ring 11 and the second mounting ring 21, the relative rotation of the mounting seat 2 and the rotating seat 1 is more stable.

[0052] Specifically, the elastic member 4 is arranged on the first mounting ring 11, and the shift portion 3 is arranged on the second mounting ring 21, wherein the snap-fit ​​portion 41 passes through from the inner periphery of the first mounting ring 11 to the outer periphery of the first mounting ring 11, so that the mounting pin 42 is installed on the inner peripheral side of the first mounting ring 11, and the shift portion 3 is a partial structure integrally formed on the second mounting ring 21, so that the blocking protrusion 32 is integrally formed on the inner peripheral wall of the second mounting ring 21, and is arranged at circumferential spacing along the inner peripheral wall of the second mounting ring 21.

[0053] Therefore, the first mounting ring 11 is covered by the second mounting ring 21 so that the elastic member 4 and the gear slot 31 cannot interfere from the outside, thereby ensuring the stability of the internal structure during use, and the mounting pin 42 is located on the side of the first mounting ring 11 away from the second mounting ring 21, so that when the two rotate relative to each other, the second mounting ring 21 cannot interfere with the mounting pin 42, thereby further ensuring the stability of the deformation and reset of the mounting pin 42.

[0054] In other embodiments, the first mounting ring 11 is sleeved on the outer circumference of the second mounting ring 21 .

[0055] Among them, in this embodiment, an L-shaped mounting cavity 22 is respectively provided on the inner circumference side of the first mounting ring 11 corresponding to each mounting pin 42, and an assembly opening 221 is provided at one end of the L-shape of the mounting cavity 22, and the direction of the assembly opening 221 is along the axial direction of the first mounting ring 11, and a positioning end 222 is provided at the other end of the L-shape of the mounting cavity 22; therefore, each mounting pin 42 enters the mounting cavity 22 from the assembly opening 221, and is elastically reset at the L-shaped intersection of the mounting cavity 22 and abuts against the positioning end 222 toward the positioning end 222, thereby realizing limited installation in the mounting cavity 22.

[0056] In addition, the first mounting ring 11 in the present embodiment is provided with a radially penetrating groove 211, and the penetrating groove 211 is extended along the axial direction of the first mounting ring 11; in addition, a C-shaped mounting portion 23 is integrally formed on the inner circumference of the first mounting ring 11, and structural protrusions 231 are integrally formed on both sides of one end of the mounting portion 23, so that the structural protrusion 231, the mounting portion 23, and the first mounting ring 11 are combined to form a mounting cavity 22, and in addition, a first limiting surface 24 is provided on the mounting portion 23, and a second limiting surface 25 is provided on the penetrating groove 211, and the spacing between the first limiting surface 24 and the second limiting surface 25 is s, and s is adapted to the thickness of the elastic member 4.

[0057] Therefore, when installing the elastic member 4, first align the installation pin 42 with the assembly opening 221, and the snap-fitting part 41 with the space between the first limiting surface 24 and the second limiting surface 25. Then, while the installation pin 42 gradually extends into the installation cavity 22, the snap-fitting part 41 gradually inserts into the penetration groove 211 by utilizing the axially extending penetration groove 211. Finally, the installation pin 42 is installed to the L-shaped intersection of the installation cavity 22. The snap-fitting part 41 is flipped to allow the installation pin 42 to enter the installation cavity 22 from a section corresponding to the assembly opening 221 of the installation cavity 22 to a section corresponding to the positioning end 222. The installation pin 42 is elastically reset and abuts against the positioning end 222 to complete the assembly. At this time, the flipped snap-fitting part 41 passes through the penetration groove 211 radially outwardly of the first installation ring 11. The overall installation process is more convenient and the installation stability is better.

[0058] In addition, each mounting pin 42 is bent at one end away from the locking portion 41 to form a bent abutment portion 43 , which abuts against the inner circumferential wall of the first mounting ring 11 to further ensure the stability of the mounting pin 42 in fitting with the positioning end 222 .

[0059] Preferably, the number of elastic members 4 is multiple, and two are specifically used in this embodiment. Each elastic member 4 is arranged along the circumferential spacing of the first mounting ring 11, and the number of the gear portions 3 is the same as the number of the elastic members 4. Each gear portion 3 is arranged along the circumferential spacing of the second mounting ring 21. In addition, a smooth arc segment 5 is arranged between each gear portion 3 on the inner circumference of the second mounting ring 21, and the elastic member 4 can rotate to the smooth arc segment 5. The clamping portion 41 abuts against the circumferential wall of the smooth arc segment 5 and maintains a stable elastic deformation, so that the elastic member 4 is in a stable state during the rotation process, does not produce a damped rotation tactile sensation, and does not produce a sound, and is a silent rotation, which can be used to turn off and start the fire. When the elastic member 4 is matched with the gear portion 3, it can be used to adjust the flame size in the firing state.

[0060] Therefore, by cooperating with the plurality of elastic members 4 and the second mounting ring 21 , the circumferential force of the second mounting ring 21 is made more uniform to ensure the rotation stability.

[0061] Embodiment 2:

[0062] like Figure 6-Figure 7 As shown, the utility model discloses an adjusting knob, comprising the damping type rotary adjusting assembly and the knob member 6 described in the first embodiment, wherein the knob member 6 and the rotating seat 1 are fixedly connected.

[0063] Therefore, the rotating seat 1 and the knob 6 cooperate, so that when the user rotates the knob 6, the rotating seat 1 can be driven to rotate synchronously, and the rotating seat and the mounting seat 2 can be rotated relative to each other for coordinated use.

[0064] The outer periphery of the knob 6 is provided with convex strips 61 to increase friction and ensure the stability of the force.

[0065] Specifically, the knob member 6 in this embodiment is located on a side of the rotating base 1 of the rotary adjustment assembly that is away from the mounting base 2 of the rotary adjustment assembly.

[0066] In addition, the fixing matching manner of the rotating seat and the knob member 6 includes the knob member 6 and the rotating seat 1 being integrally formed or being directly attached with glue.

[0067] The method of this embodiment is as follows: a first snap-fitting protrusion 13 with a cylindrical outer circumference is protruded from the rotating seat 1 toward the side of the knob member 6, and a plurality of second snap-fitting protrusions 14 are arranged at circumferential intervals along the first snap-fitting protrusion 13; correspondingly, the knob member 6 is provided with a first installation slot 62 for the first snap-fitting protrusion 13 to be inserted into, and a second installation slot 63 for each second snap-fitting protrusion 14 to be inserted into, so that assembly is performed in a double snap-fitting manner. In addition, according to requirements, the rotating seat 1 and the knob member 6 can be bonded or only snap-fitted, and the snap-fitting method is convenient for disassembly, replacement and maintenance.

[0068] The end of the knob 6 facing away from the rotating seat 1 is also provided with an indicator 64, so that when the knob 6 is rotated, the indicator 64 rotates circumferentially to indicate the rotation amplitude of the knob 6, which has a visual indication function.

[0069] Embodiment three:

[0070] like Figure 8-Figure 9 As shown, the utility model discloses a regulating valve, including a regulating valve body 7 and the regulating knob described in the second embodiment, wherein an adjusting shaft 71 is rotatably arranged on the regulating valve body 7; wherein the mounting seat 2 is fixedly mounted on the regulating valve body 7 by bonding, bolting, clamping, etc.; wherein, in this embodiment, the adjusting shaft 71 is plug-in fixedly connected to the knob member 6, and in other embodiments, the adjusting shaft 71 may also be fixedly connected to the rotating seat 1.

[0071] Therefore, the regulating valve formed by assembling the above structure drives the rotating seat 1 to rotate relative to the mounting seat 2 by rotating the knob member 6, thereby realizing tactile and auditory prompts through the cooperation of the elastic member 4 and the shift portion 3, and the operation indication capability is stronger.

[0072] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
