Description

Fuel gas and gas switching switch and ignition and gas regulating device for shared stove

The utility model relates to a switching switch for fuel gas and gas and an ignition and gas regulating device for a shared stove, in particular to an air adjustment button to form fuel and gas fuels that can light a strong fire and use and supply different air volumes Stove improved structure.

Commonly used gas stoves are all designed for gas as fuel, and it is not yet possible to share oil and gas such as fuel oil without adjusting the air intake.

It has been found through actual testing that both fuels and gas with a larger air intake can be ignited independently.

At present, about 99% of households or catering establishments use gas as the main fuel, and a small number of equipment use electrical appliances.

Since the suction adjustment of the gas stove does not need to be adjusted in long-term use after the suction volume is set, the suction adjustment plates are all located on the inner surface of the furnace body, and cannot be adjusted directly from the outside. The bottom of the stove or raise the stove obliquely can be adjusted. In addition, the ignition nozzle attached to the electronic switch installed on the gas stove, because the gas injection force is concentrated, if the same method and structure are applied to the fuel gas, if the fuel gas is ignited under the fire state The road guides the flow at a high speed, and the oil and gas provided by the fuel cannot be ignited because the flow speed is too fast. It can only be replaced with a dedicated stove or a pre-set medium-volume gas supply. So far, there is no available fuel gas and gas in the market or households that can be switched at any time and used in one stove. Therefore, the promotion of fuel oil, Encountered a lot of obstacles, because it is a burden to the user to replace the stove when switching between shared fuel gas and gas, and because the use of fuel (green) oil requires electricity, if there is a power outage, unless there is an attached There is a battery, that is, the use of oil and gas cannot be provided, and the special stove needs to be equipped with a transformer, an automatic gas control switch and a special electronic switch, which doubles the cost, so it is not popular. In order to solve the above-mentioned problems, the creator actively developed the utility model. Oils with names such as green seed oil, atomic oil and Quaker oil are all called fuel oils in the utility model, so that they can be used in the utility model. in the structure. Because the main components of the above-mentioned various oils have similarities and differences, mainly containing about 62% of isopentane and about 19% of n-pentane, etc., they have the characteristics of high ignition point, no gas explosion, no poisoning, and high combustion energy.

The purpose of this utility model is to provide a fuel gas and gas switching switch and an ignition and gas regulating device for a shared stove, so that fuel gas and gas can be used in both old and new stoves, and the effect in use is better than that of gas, which can not only solve the Use problems, and can solve the problem of storage.

When the fuel gas and gas in use can be shared in the same stove, because the electronic ignition device of the commonly used stove is made with gas as fuel, it is necessary to improve the electronic ignition structure using fuel gas as a raw material.

The ignition point of the gas is low, and the jet force of its ignition can attract a large amount of air to support combustion and completely burn the gas at the same time. However, fuel gas has a higher ignition point, and the air content after mixing with air in the barrel is high, so it is not easy to ignite under strong jet concentration. Therefore, it is necessary to add barrier oil and gas in the duct or net groove of electronic ignition to block the powerful jet of oil and gas, so that the oil and gas can be ejected. If the flow is eased, it is very easy to ignite the burner nozzle with fuel gas or gas in the state of a big fire.

In addition, the large amount of air required for gas and the adjustment of a small amount of air required for fuel gas can be changed to operate outside the stove. However, because the brands and structures of gas stoves used in general households are different, it is difficult to install components with fixed dimensions. It must be divided into two categories: (1) stoves in use; (2) new product specifications; for various brands in use, the simplest and most economical method is to drill a hole in the ear of the original suction plate, and then connect it. After the last iron wire passes through the side of the furnace, the iron wire is connected with a stop ring, which can be pushed and pulled to adjust the diameter of the suction hole in the range of 50 to 60 degrees, realizing one adjustment method; the other preset is used for new On the furnace, add a coil spring to the center of the suction adjustment plate forward to the suction port, so that its outer diameter is set as a cap edge lip facing forward, and then it is set at about 70 degrees into a perforated female tooth shape, and the side is meshed In the same way, only a male gear with an angle of about 50 degrees is set, so that the two mesh and open and close the valve in the range of 50 to 60 degrees, so as to be suitable for the maximum air demand of gas and the minimum intake of fuel. The tail end of a shaft is inserted through the rear wall of the stove or the U-shaped cross bar so that it can be clamped back and forth so that it can be twisted, but it will not move forward and backward. The rod seat is fixed, and a twist sleeve is added to the front end of the shaft rod to adjust the air intake required for fuel and gas.

The structure of the utility model is: because the fuel gas needs to share the stove with the gas, the problem of ignition must be solved first. Since the ignition point of the gas is lower than that of the fuel oil, the ignition outlet hole of the gas is slightly larger, and it is easy to ignite, because the greater the injection force, The more air follows, the higher the probability of gas being ignited. On the contrary, the gas ignition point of fuel is higher, and it is not easy to ignite under the large injection of fuel gas. The space between the boards is equipped with cap-shaped iron nets, torsion iron nets, torsion springs, irregular twisted iron wires, etc. as obstacles to obstruct the air, so that the jet oil and gas can flow gently after passing through the obstacles. Easy to ignite.

The gas suction adjustment structure of the furnace nozzle is aimed at the low ignition point of the gas, so it is necessary to absorb a large amount of external air and enter it from the suction port to support the combustion. On the contrary, the fuel oil has a high ignition point and requires a small amount of external air. Under this difference, When cooking, the fire of fuel is used as the main source; when cooking soup, it is used instead of gas. This switch needs to adjust the amount of suction so that the fuel can fully burn completely. The manual operation structure originally installed in the furnace is very inconvenient. In order to facilitate the adjustment outside the furnace, there are two methods. One is applied to the old furnace, and the suction adjustment plate is connected by the hole at the protruding ear. There is an iron wire, so that after the iron wire passes through the side of the furnace, the iron wire is connected with a retaining ring, which can be pushed and pulled to adjust the diameter of the suction hole in the range of 50 degrees, realizing an adjustment method; another preset is used for new On the furnace, set the suction adjustment plate forward and put a coil spring on the periphery of the fuel injection pipe against the suction port, so that the outer diameter is facing the front lip of the cap, and then set its eighty-degree diameter to be the same as the perforated female tooth-shaped meshing side Only set the male gear with a diameter of 50 to 60 degrees, so that the two mesh with each other to open and close the valve within 50 to 60 degrees, so as to be suitable for the maximum air demand of gas and the minimum intake of fuel oil. Connect the tail end of a shaft and insert it through the rear wall of the stove or the U-shaped cross bar so that it can be clamped back and forth so that it can be twisted, but it will not move back and forth. A rod seat is fixed, and a twist sleeve is added to the front end of the shaft rod to adjust the required air intake for fuel and gas.

However, when the above-mentioned shared stove burns fuel gas alone instead of using gas as fuel, it can be exempted from installing gas regulating components and dissimilar fuel switching switches, and still needs to be improved by adding obstacles between the electronic ignition and the fuel injection port. , and after adjusting the gas, there is no need to adjust the gas again, that is, the burner nozzle can be ignited for a long time.

As shown in Figures 1 to 10, it is a fuel gas and gas switching switch and an ignition and gas regulating device for a shared stove of the present utility model, including: a gas barrel 1, a fuel barrel 2, and a shared stove 3 1, a switching switch 8 and other components, the gas barrel 1 is screwed to fix an air pressure regulator, and connected to a switching switch 8 with a pipeline 11, and the electromagnetic pump 4 presses the air into the barrel through the pipeline and overflows through the straight-through pipe. Air and fuel are stirred into oil and gas, and after the fuel tank 2 is screwed into an air pressure regulator, it is also connected to the switch 8 with a pipeline 21, and the switch 8 is connected to the shared stove 3 with a common pipeline 31, and the common The structure on the stove 3 is basically the same as the general gas stove, and also has a burner 32 and an electronic ignition device 33. The difference of the present utility model is that the structure at the ignition nozzle is improved and the external control type is added. The suction adjustment device 40 at the mouth of the burner.

Because the electronic ignition device 33 in the commonly used stove 3 is specially designed to use gas as fuel, the ignition point of gas is low, and the gas ejection speed of gas is slow, so it is very suitable for large fires where strong jets attract external air. Ignition, on the contrary, fuel oil has a high ignition point and is saturated with air, so it is not easy to ignite under a strong jet. Therefore, commonly used electric fuel tanks are equipped with air pressure regulators to set the flow of oil and gas at a medium fire state so that it can be easily ignited. , that is, in addition to the operation of not being able to ignite the fire, the related costs will also increase significantly. Therefore, the price of this type of electro-pneumatic oil tank is high and cannot be accepted by consumers, which will affect the utilization rate of fuel and the sales of stoves and fuel tanks. But did not expect to be improved by the jet structure of the ignition device, the utility model at first improves at above-mentioned position, to produce the shared stove 3 that can be applicable to fuel gas and gas simultaneously.

As shown in Figures 2 and 3, the switch button 34 of the ignition device 33 is installed on the front end surface 30 of the stove 3. When the switch button 34 is pressed and turned to the left to 90 degrees, a lightning bolt extending in the furnace will appear. The needle 35 generates electricity due to the friction between each other while rotating, so that the lightning needle 35 generates an electric current, and conducts electricity towards the opposite lightning sharp plate 36 to generate sparks. The fuel gas leads the air to pass through, and the gas will instantly ignite with lightning. However, when the fuel gas is ejected at a slightly stronger pressure, it cannot be ignited. Different, some are equipped with conduits, and some are provided with mesh grooves, that is, one of the following obstacle oil and gas objects 39 is added and fixed in the conduit or mesh grooves, which are: (1) more than one layer of cap-shaped refractory ferroalloy mesh, Such as white iron net; (2) twisted iron net; (3) hat-shaped torsion spring; (4) iron wire twisted into irregular shape; (5) tube cap-shaped porous barrier body; When the flow of fuel gas is relaxed, it is very easy to ignite the fire source at the burner nozzle in a state of high fire.

In addition, the suction adjustment device 40, as shown in Figures 2, 4, and 5, is provided with a twist sleeve 41 on the front end 30 of the stove 3, and the twist sleeve 41 is sleeved with a front and rear shaft 42, the shaft 42 is a pivot Connected between a front fixing seat 43 and a rear fixing seat 44, each fixing seat is screw-fixed on the front and rear end surfaces of the stove 3, and the front section of the shaft rod 42 is provided with a driving tooth with only a seventy-degree range near the air suction plate 47. The gear 45 of the part 46 is meshed with the passive tooth part 48 in the range of 50 to 60 degrees on the air suction plate 47, which can make the torsional movement adjustment space of about 50 to 60 degrees between the two teeth. It can cooperate with the required small air intake of fuel gas, and the air intake 49 can be closed down. In addition, when it needs a large air intake when cooperating with gas, it can be adjusted on and off. Because the air intake plate 47 is worn Fixed in the furnace inside the fuel injection pipe 510 peripheral sleeve through a helical spring 51 bounce against the mouth of the burner at the right side of the outer ring suction port 49, so that the air from the hole 52 on the suction plate of the suction port together The outer ring burner nozzle of the gas or oil suction burner head, and the air required for burning fuel gas or gas from the suction port 50 of the inner ring on the left to the central burner nozzle is not much different, so no adjustment is made to avoid increasing the complexity of the operation And increase cost, just this suction plate is locked on the required average suction volume of two kinds of fuels and also has same effect by the firepower of outer ring again.

The above-mentioned structure cooperates with the domestic gas stove for fuel gas sharing, so that different fuels can be completely burned, and the suction adjustment must be done. The above-mentioned structure may not be suitable for all types or sizes of stoves. In the past, this kind of stove was only aimed at using a single type of gas as fuel, and its air intake would not be adjusted for several years after the new furnace set the air intake. The suction demand is different, so it is necessary to switch the fuel and adjust the suction volume at the same time. For convenience, the old stoves in use can be shared. There is also the simplest and most economical method, which is to drill a hole in the ear part 54 of the original suction plate 53 55, after piercing a white iron wire 56 and passing through the small hole on the furnace front face or the top side right side, the upper end of the white iron wire 56 is twisted into a twisted pull ring 57, so that the suction port 49 when pulling upwards is drawn Suction plate 53 blocks into small holes and is suitable for fuel gas burning in burner nozzle 3 fires, otherwise the pull and pressure handle 274 is pushed downwards to make the suction port hole enlarged, suitable for gas burner nozzle 32 to ignite a large fire that burns completely. Furnace nozzle 3 is all made two mouthfuls with general family, also has one mouthful or three mouthfuls, all can be it with identical structure, but when burning fuel oil gas alone, can exempt above-mentioned gas-regulating structure and different fuel switching switch.

The diverter switch 8 for different fuels is used to switch between gas and fuel gas, which can prevent the fuel oil used in cooking from being cut off due to power failure or running out of individual fuels. The pipe connected to the diverter switch 8 is connected to the fuel gas at one end The oil and gas outlet pipeline 21, the other end is connected to the gas outlet pipeline 11 of gas gas. When the handle is turned to turn to the fuel gas pipe, the fuel gas is delivered to the common stove 3 by the switch through the shared air guide pipe 31, otherwise the switch 8 When turning to the gas, the gas will be transported to the common stove 3 through the switch 8 through the common air duct 31 pipeline. If only one kind of fuel gas is used alone, there is no need to install the switch.

The diverter switch 8 is provided with two different structures, as shown in the conical plug two-way valve in Figures 9 and 10 and the columnar two-way ball valve in Figures 7 and 8 respectively. The on-off valve 81A formed by the switching switch 8 is a longitudinal circular diameter rod. The inner diameter of the upper half section 82A is the same, and the lower half section is tapered downward by 82A to become a narrower rod diameter 83A, which is wide at the top and narrow at the bottom. Two rubber rings 84A are added at appropriate places on the upper part of the diameter section 83A, and an angular perforation 88 is provided in the lower end of the rod diameter section 83A. OD threaded screw-on. As shown in Figures 7 and 8, the entire section of another switch valve 81B has the same circumference, and two rubber rings 84B are added at appropriate places between the upper sections of the cylinder, and the slightly lower end is set to be larger. Add a horizontal convex key 83B at the bottom of the diameter, which can be embedded in the horizontal notch at the top of the ball 85B, so that the twist handle 86 drives the ball 85B to follow and turn when turning. The ball 85B between the switch and the three-terminal pipe is provided with a ball seat 82B, and an angular perforation 88 is provided in each ball seat 86, and the three-end pipe is extended by the seat body 80B, 80A to form a ratchet on the outside. Shape joint 87, for inserting pipeline 11,21,31. The different fuel changeover switch 8 is similar in that a twist handle 86 is screwed on the top of each switch seat. The angular perforation 88 is set so that when the twist handle 86 is turned towards the fuel gas outlet pipeline 21, the oil and gas of the fuel will be diverted and transported to the stove 3 by the common air guide pipe 31, otherwise the twist handle 86 will be turned towards the gas gas The gas outlet pipeline 11 is about to transport the gas from the common pipeline of the gas guide pipe 31 to the common stove 3 for use with the ignition switch 34 for lightning ignition and combustion. The direction of the above-mentioned knob 86 can also be changed according to the needs and different positions of the pipe holes. The different fuel switching switch can use either gas or fuel gas, and can switch to gas at any time, which can prevent the oil and gas from being cut off due to power failure. And it can achieve the state of closing and not switching. Among them, because the gas content of the fuel gas is relatively rich, and the gas output volume adjusted by the air pressure is large, and the gas has a low ignition point, its air pressure is low, and the fuel tank 2 is equipped with an air pressure regulator and is assisted by the air at the suction port. Therefore, the gas It will never intrude into the fuel barrel, and vice versa, the fuel will not invade the gas barrel. Another function of the air pressure regulator is to only allow the fuel in the barrel to output and prevent the external air pressure from entering. Therefore, the mixed fuel supply of the two is absolutely safe. Closing unused gas or fuel gas switch can burn a single fuel, and if the aperture of the angular perforation 88 of the switch valve 81 is enlarged, when the twist handle 86 is turned to the center, the two fuels can be used simultaneously, but only Make firepower slightly increase, but can't shut down two kinds of fuels simultaneously.

To sum up, the utility model achieves the function of easy ignition by the obstacle oil and gas on the ignition device, and the additional suction adjustment device is suitable for the new model and the old model respectively, which can burn oil and gas separately, and then The function of changing the fuel type is achieved by a switch, which can be replaced with fuel oil or gas as needed. There are not many structures added overall, but it can improve its commonality and produce different effects from the past.
