Description

Technical Field

[0001] The utility model relates to the technical field of stove accessories, in particular to a gas pressurizing mechanism for a gas stove. Background Art

[0002] A gas stove is a kitchen appliance for heating and cooking food. When the gas stove is working, gas enters the stove from the air inlet pipe, enters the burner after being adjusted by the regulating valve (the user adjusts it through the knob), and mixes with a part of the air at the same time. After the mixed gas enters the ignition distributor, it is ignited by the ignition device and ejected from the fire hole to form a flame, which is used to heat the pot placed on the pot support.

[0003] Since the cooking time of household users is relatively concentrated, and the gas pressure supplied by the external gas supply department is certain, when multiple users use the gas stove to cook at the same time, there will be insufficient gas supply pressure, insufficient firepower of the gas stove or even failure to ignite. In addition, during the cooking process, some users like to cook dishes that suit their taste by stir-frying with high heat. However, during the working process of the existing gas stove, its firepower cannot meet the burning flame for stir-frying with high heat, so that when users cook dishes at home, it is difficult to obtain the same taste as the dishes stir-fried with high heat using commercial stoves in hotels, which greatly reduces the user experience.

[0004] The prior art device generally sets an additional mixing valve between the gas pipe and the regulating valve. The mixing valve is generally a one-way valve. The mixing valve is generally provided with a gas pressurizing structure, such as a fan light structure. Air is injected into the mixing valve through the gas pressurizing structure. The air and gas are mixed in the mixing valve and then enter the regulating valve.

[0005] In the actual use process of the prior art, the adjustment range of the amount of air injected into the mixing valve is reduced and cannot meet the diverse needs. Therefore, we believe that a gas boosting mechanism for a gas stove with greater adjustment is needed. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model proposes a gas booster mechanism for a gas stove, which has the advantages of a wide adjustment range and meeting diverse needs, and solves the shortcomings of the prior art devices that have a small adjustment range and cannot meet user needs.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A gas booster mechanism for a gas stove comprises a mounting shell, wherein upper and lower sides of one end of the mounting shell are respectively fixedly connected with a left and right axial flow tube, the flow tube is communicated with the mounting shell, a driven ring is coaxially arranged in the inner cavity of each flow tube, a baffle is rotatably connected to the inner side of the driven ring through a pin shaft, each baffle is rotatably connected to a follower rod near one end of the mounting shell, the upper and lower sides inside the mounting shell are respectively rotatably connected with a drive plate, a drive shaft is eccentrically fixedly connected to the drive plate, two drive plates correspond to the two flow tubes one by one, and the movable end of each follower rod is rotatably connected to the drive shaft.

[0009] Preferably, among the two flow pipes, the relatively upper flow pipe is the air outlet pipe, and the relatively lower flow pipe is the air inlet pipe. The inner side of the driven ring is fixedly connected to the limiting plate, the driven ring in the air outlet pipe is fixedly connected to the limiting plate on the side close to the mounting shell, and the driven ring in the air inlet pipe is fixedly connected to the limiting plate on the side away from the mounting shell, and the limiting plate abuts against the corresponding baffle.

[0010] Preferably, a sealing ring I made of rubber is coaxially fixedly connected to the outer side of the driven ring and the inner side of the circulation tube, and the sealing ring on the outer side of the driven ring and the sealing ring I on the inner side of the circulation tube are interference fit.

[0011] Preferably, both flow pipes are trumpet-shaped structures, and the diameter of the air inlet pipe close to the mounting shell is larger than the diameter of the air inlet pipe away from the mounting shell, and the diameter of the air outlet pipe close to the mounting shell is smaller than the diameter of the air outlet pipe away from the mounting shell.

[0012] Preferably, a sealing ring II made of rubber is fixedly connected to the inner side of the driven ring, and the difference between the outer diameter of the baffle and the inner diameter of the driven ring is smaller than the thickness of the sealing ring II.

[0013] Preferably, a driven gear is fixedly connected to one side of each of the driving plates, the two driven gears are in the same vertical plane, and the two driven gears are meshed and transmission-connected with a driving gear.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model sets a driven ring in the flow pipe, and shields the inner cavity of the driven ring by a baffle rotatably connected to the driven ring, so that the device can press the external gas into the corresponding valve body through the flow pipe to mix with the fuel gas by changing the direction of the central axis of the baffle as needed. Compared with the existing technology device, the device is more proactive and can flexibly adjust the rate of pressing air into the corresponding valve body as needed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Please refer to Figure 1-4 A gas boosting mechanism for a gas stove includes an installation shell 2. In practice, the installation shell 2 is fixed in the inner cavity of the stove body. In this application, for ease of understanding, the stove body related structure is omitted. This is common knowledge known to those skilled in the art and will not be repeated here.

[0024] Similarly, the device is connected to a left and right axial flow pipe 1 on the upper and lower sides of one end of the installation shell 2, wherein the relatively upper flow pipe 1 is the air outlet pipe 102. In practice, the air outlet pipe 102 needs to be connected to the gas pipe through the corresponding valve body, and the air inlet pipe 101 and the gas pipe synchronously inject gas into the corresponding valve body, which is then sprayed out through the burner after mixing.

[0025] It should be noted that, of the two flow pipes 1 , the relatively lower one is the air inlet pipe 101 , and the outside air enters the installation shell 2 through the air inlet pipe 101 , and then flows into the air outlet pipe 102 through the installation shell 2 .

[0026] Specifically, the device is provided with a driven ring 8 inside the two circulation tubes 1, and the inner side of the driven ring 8 is rotatably connected with a baffle 10 through a pin shaft 11. Therefore, when the central axis of the baffle 10 coincides with the central axis of the driven ring 8, the baffle 10 can shield the central cavity of the driven ring 8. At this time, when the driven ring 8 moves inside the circulation tube 1, it can drive the gas to move. When the central axis of the baffle 10 does not coincide with the central axis of the driven ring 8, the central cavity of the driven ring 8 is exposed. At this time, the gas can flow on the left and right sides of the driven ring 8.

[0027] Furthermore, in the device, a sealing ring II9 made of rubber is fixedly connected to the inner side of the driven ring 8. The sealing ring II9 ensures that when the central axis of the driven ring 8 coincides with the central axis of the baffle 10, the baffle 10 can completely shield the central cavity of the driven ring 8.

[0028] Therefore, in the device, a limit plate 12 is fixedly connected to the inner side of the driven ring 8 , and the rotation range of the baffle 10 is restricted by the limit plate 12 .

[0029] Specifically, in this device, each baffle 10 is rotatably connected to a follower rod 6 near the mounting shell 2 , which cooperates with the pin shaft 11 so that the user can pull the baffle 10 and the driven ring 8 through the follower rod 6 to perform linear motion in the corresponding flow pipe 1 .

[0030] Therefore, the device constrains the driven ring 8 in the outlet pipe 102 to be fixedly connected to the limiting plate 12 near the side of the mounting shell 2. This ensures that when the driven ring 8 in the near pipe is pushed to move to the left by the follower rod 6, the central axis of the driven ring 8 and the baffle 10 do not coincide. At this time, the outside gas enters the right side of the driven ring 8. After that, the driven ring 8 in the intake pipe 101 continues to be pulled to the right by the follower rod 6. Then, when the amount of gas inside the mounting shell 2 does not change, the gas in the intake pipe 101 can be pressed into the mounting shell 2 by utilizing the characteristic that the central axis of the driven ring 8 and the baffle 10 coincide. At this time, the air pressure value inside the mounting shell 2 increases.

[0031] This device constrains the driven ring 8 in the air inlet pipe 101 to be fixedly connected to the limiting plate 12 away from one side of the mounting shell 2. This ensures that when the driven ring 8 in the air outlet pipe 102 is pushed to the right by the follower rod 6, the central axis of the driven ring 8 and the baffle 10 do not coincide. At this time, the internal gas of the mounting shell 2 enters the right side of the driven ring 8. Thereafter, the driven ring 8 in the air outlet pipe 102 is continued to be pulled to the left by the follower rod 6. Under the condition that the amount of gas in the mounting shell 2 does not change, the gas in the air outlet pipe 102 can be pressed into the corresponding valve body to mix with the fuel gas by utilizing the characteristic that the central axis of the driven ring 8 and the baffle 10 coincide. At this time, the internal air pressure value of the mounting shell 2 is reduced.

[0032] Therefore, it is necessary to emphasize that, in practice, by constraining the driven rings 8 in the two flow pipes 1 to maintain a moving state with opposite directions of movement, the external air can be continuously pressed into the corresponding valve body to mix with the fuel gas.

[0033] Furthermore, the device has a sealing ring Ⅰ7 made of rubber coaxially fixedly connected to the outside of the driven ring 8 and the inside of the circulation tube 1, which constrains the interference fit between the sealing ring on the outside of the driven ring 8 and the sealing ring Ⅰ7 on the inside of the circulation tube 1, thereby promoting the gas flow to change the internal air pressure value of the installation shell 2 when the central axis of the driven ring 8 and the baffle 10 coincide.

[0034] Furthermore, the present device constrains the two circulation pipes 1 to be a trumpet-shaped structure, and the diameter of the air inlet pipe 101 close to the mounting shell 2 is larger than the diameter of the air inlet pipe 101 away from the mounting shell 2, and the diameter of the air outlet pipe 102 close to the mounting shell 2 is smaller than the diameter of the air outlet pipe 102 away from the mounting shell 2. This can fully ensure that when the air pressure value inside the mounting shell 2 is not equal to the atmospheric pressure, the driven ring 8 and the circulation pipe 1 can still maintain a sealed state.

[0035] Furthermore, the trumpet-shaped structure enables the driven ring 8 to push a larger amount of gas during the process of moving the driven ring 8 , and the air pressure value inside the mounting shell 2 changes more dramatically.

[0036] Specifically, in order to achieve completely opposite movement directions of the two driven rings 8, the device is rotatably connected to a drive plate 5 at the movable end of each follower rod 6, and a drive shaft is eccentrically fixedly connected to the drive plate 5, and the drive shaft is rotatably connected to the follower rod 6. At this time, it is only necessary to keep the two drive plates 5 rotating in opposite directions.

[0037] Specifically, the device is provided with a driven gear 3 on one side of the two driving plates 5, the two driven gears 3 are in the same vertical plane, and a driving gear 4 is meshingly connected between the two driven gears 3. The single driving gear 4 can fully ensure that the two driven gears 3, that is, the two driving plates 5 keep rotating in opposite directions.

[0038] It should be noted that, as shown in the figure, the device is also provided with a corresponding driving mechanism on one side of the driving gear 4 to ensure that the device can function normally, and the corresponding driving mechanism can be in the form of a driving motor.

[0039] In the actual use of the utility model, as the driving gear 4 rotates, the two driven gears 3 drive the driving plate 5 to rotate in opposite directions. At this time, the two driven rings 8 move in completely opposite directions driven by the follower rod 6.

[0040] Therefore, in practice:

[0041] First, the driven ring 8 in the air inlet pipe 101 moves to the left, and the driven ring 8 in the air outlet pipe 102 moves to the right. At this time, the central axes of the two driven rings 8 do not coincide with the central axis of the baffle 10, and the outside air directly enters the air outlet pipe 102;

[0042] Afterwards, driven by the follower rod 6, the driven ring 8 in the air inlet pipe 101 moves to the right, and the driven ring 8 in the air outlet pipe 102 moves to the left. At this time, the central axes of the two driven rings 8 coincide with the central axis of the baffle 10. At this time, the driven ring 8 in the air inlet pipe 101 presses the gas in the air inlet pipe 101 into the installation shell 2, and the driven ring 8 in the air outlet pipe 102 presses the gas in the air outlet pipe 102 into the corresponding valve body. At this time, the interior of the installation shell 2 is basically kept at atmospheric pressure;

[0043] Finally, the two driven rings 8 continuously perform left-right linear reciprocating motion, and the device continuously presses gas into the corresponding valve body.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
