Description

Mechanical double-sleeve adjusting mechanism and commercial cooking stove Technical Field The invention relates to the technical field of stoves, in particular to a mechanical double-sleeve adjusting mechanism and a commercial stove. Background The cooking range is kitchen equipment for cooking, and heat is supplied to the cookware by burning fuel. In the field of liquid or gaseous fuel burners, it is critical to achieve high combustion efficiency, with a near or even optimal air-to-fuel ratio. The air-fuel ratio and the air-fuel ratio of the stove refer to the ratio of air quality to fuel quality in the mixed gas, and the combustion efficiency and stability are directly affected. For example, a gas stove using natural gas as fuel needs to be accurately controlled to be 10.5:1, the insufficient air can cause incomplete fuel combustion, harmful gases such as carbon monoxide and the like are generated, meanwhile, the flame is yellow and low in temperature, and the excessive air can reduce the combustion efficiency and even cause flame extinction. The realization path of the traditional commercial stove using fuel oil/gas as fuel and air as combustion improver is as follows: 1. The wind is controlled by manually adjusting the wind door. For the fuel flow under different firepower, an operator manually adjusts the opening and closing degree of the air door under the condition that the fan does not regulate the speed, so as to achieve the purpose of matching oxygen supply with fuel supply. The scheme is difficult to realize accurate air-fuel ratio/air-fuel ratio matching, and operators tend to be flawless in actual operation and accurately debug the operation in time, so that the combustion efficiency is low; 2. the fuel proportioning valve is matched with the air supply for control. The controller controls the fuel proportioning valve to control the fuel supply for different fire gears. Meanwhile, the frequency conversion speed regulation of the fan or the control of the opening and closing degree of the air door is used for matching air supply. The scheme needs to apply a large number of electronic components and wiring connectors, and has limited tolerance to high temperature, high humidity, high oil smoke, even acid-base environment; 3. The fuel valve is matched and adjusted in rough association with the throttle opening and closing degree. The specific method is that under the condition that the fan does not carry out speed regulation, the fuel supply valve and the air supply valve realize shaft-shaft mechanical linkage control through coaxial control or a gear, a connecting rod mechanism or a belt type fixed transmission ratio mechanical structure. The throttle of this mode opens and shuts mostly and rotates the butterfly valve design, and the trompil design of seting up cylindrical channel on most spherical case of fuel valve case is because the ratio of fuel and air is fixed numerical value, consequently, this design can only realize the positive correlation control of fuel and air feed, can't reach the effect of accurate control. In summary, the manual air door is manually operated, the air-fuel ratio/air-fuel ratio is difficult to be precisely matched, the efficiency is low, the frequency conversion or air door linkage control of the fuel proportional valve and the fan is required, more electronic elements are required, the reliability is limited in severe environments such as high temperature, high humidity, lampblack and the like, the mechanical linkage control is carried out, and the fuel valve and the air door are synchronously regulated through mechanisms such as a coaxial mechanism, a gear mechanism and the like, but only the fixed proportion can be realized, and the precise control requirement cannot be met. All three have limitations in terms of control accuracy, environmental adaptability, or structural complexity. Disclosure of Invention The invention provides a mechanical double-sleeve adjusting mechanism and a commercial stove, which can be widely applied to fuel oil and gas type stoves, and a combustion improver can be air, oxygen or other combustion-supporting media. The method can solve the problems that in the prior art, a manual air door is dependent on manual operation and is difficult to accurately match with the air-oil ratio/air-fuel ratio, so that the combustion efficiency is low, in the variable frequency control of a fuel proportional valve and a fan or the linkage control of the air door, the reliability is limited in severe environments such as high temperature, high humidity, lampblack and the like, and in the mechanical linkage control, only fixed proportion can be realized and the accurate control requirement cannot be met. The invention discloses a mechanical double-sleeve adjusting mechanism which comprises an inner cylinder and an outer cylinder, wherein the inner cylinder and the outer cylinder are coaxially arranged, the inner cylinder can coaxially rotate in the outer
