Description

Technical Field

[0001] The utility model relates to the field of kitchen utensils and equipment, in particular to a double-damping gear adjustment handle. Background Art

[0002] At present, in the kitchen stove equipment, the fuel delivery amount is generally changed by adjusting the mechanical handle valve or the straw hat knob encoder to achieve the change of firepower. The mechanical handle valve is easy to operate and has a uniform feel, but it has the following disadvantages: 1. The fuel is delivered by changing the opening and closing degree of the valve, which is not precise. It is not easy for the chef to master the fine control of the firepower and cannot achieve fine adjustment of the firepower; 2. The seals of the mechanical valve are easily corroded by the fuel for a long time, which can easily lead to valve leakage and safety accidents. The straw hat knob encoder adjustment uses a microcomputer controller to adjust, and the controller outputs different voltages to the electromagnetic pump (valve), which controls the pressure and flow of the fuel delivery, and achieves precise control and fine adjustment of firepower. However, there are also the following disadvantages: 1. The straw hat knob encoder is small in size, has no suitable grip and damping, and is difficult to control during adjustment; 2. The chef's hands are full of oil and water during operation, which increases the risk of misoperation.

[0003] Therefore, the field of kitchen utensils and appliances is in urgent need of a technology and product that fully solves the above problems. Utility Model Content

[0024] The partition 5 is provided with a circuit board mounting column 13 and a spring column 14 in the direction of the lower cavity 7. The partition 5 is provided with a first pressing plate 15, a grinding plate 16 and a second pressing plate 17 in sequence in the direction of the lower cavity 7. One end of the rotating shaft 12 passes through the first pressing plate 15, the grinding plate 16 and the second pressing plate 17. The first pressing plate 15 and the second pressing plate 17 are both provided with a mounting column avoidance hole 18 and a spring column avoidance hole 19. The mounting column avoidance hole 18 is slidably connected with the mounting column 13, and the spring column avoidance hole 19 is slidably connected with the spring column 14.

[0025] The partition plate 5 is further provided with a limit stopper 20 and a spring hole 21 in the direction toward the lower cavity 7 . The limit stoppers 20 are arranged in groups of two, and there are two groups in total. The two groups of limit stoppers 20 are symmetrically arranged on the partition plate 5 .

[0026] The spring column 14 and the spring hole 21 are both provided with springs.

[0027] Blocks 24 are disposed at both ends of the second pressing plate 17 , and the two blocks 24 are respectively disposed between the two groups of limit blocks 20 .

[0028] The upper surface and the lower surface of the second pressing plate 17 are both provided with grinding grooves 25, and the grinding grooves are annular grooves.

[0030] A stud 22 is disposed at the side end of the middle cover 1 , and a reinforcing rib 23 is disposed on the stud 22 .

[0031] Specifically, the spring on the spring column presses the second pressure plate, and the second pressure plate presses the grinding plate after being subjected to force. At the same time, the spring on the spring hole presses the first pressure plate, and the first pressure plate presses the grinding plate. Therefore, the grinding plate is subjected to elastic pressure at both ends, so that the rotation of the handle has a damping feeling. Due to the double-sided pressure, it has double damping.

[0032] Specifically, the grinding plate adopts an annular grinding pattern, and the grinding pattern is provided with lubricating oil, so when the grinding plate rotates, it is not easy to wear.

[0033] Specifically, a waterproof gasket is provided, and the circuit board is arranged in the lower cavity, so that oil and water are not easy to enter the circuit board.

[0034] Specifically, reinforcing ribs are provided to make the overall structure less likely to loosen or be damaged.

[0035] Specifically, the end of the rotating shaft is connected to an adjustable element of a circuit board. By turning the handle, the adjustable element on the circuit board changes its value and transmits it to the processor, thereby controlling the change in the output of firepower.

[0036] Specifically, the circuit board is installed in the lower cavity 7 and connected to one end of the rotating shaft.

[0037] Specifically, the end of the rotating shaft is connected to the adjustable element of the circuit board, and one end of the circuit board is connected to the microcomputer controller through a transmission line. By turning the handle, the rotating shaft also changes its angle accordingly, and the adjustable element generates a uniform electrical signal which is transmitted to the microcomputer controller through the transmission line. The controller outputs different voltages to the electromagnetic pump (valve) accordingly, and the electromagnetic pump (valve) controls the pressure and flow of fuel delivery, thereby achieving precise control and fine-tuning of firepower. The technical difficulties of the above-mentioned background technology are completely solved.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
