Description

Technical Field

[0001] This utility model relates to the technical field of gas stove accessories, and in particular to the structure of the venturi tube in a gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses combustible gas as fuel for direct-fire heating. It is extremely common in modern homes and commercial kitchens. Combustible gas is introduced into the stove through a gas pipeline. When the user opens the gas valve and presses the ignition device, the ignition device generates an electric spark or a continuous flame, which ignites the mixture of gas and air sprayed from the nozzle, forming a stable combustion flame. The heat generated by the flame is used to heat the pots and pans placed on the stove rack, thereby achieving the purpose of cooking food.

[0003] When using a gas stove, air and gas are usually introduced and mixed. However, in the current technology, when air is mixed with gas through the air inlet and gas through the gas inlet, the mixing is not very uniform. If the air and gas are not mixed uniformly, some gas may not burn completely due to insufficient oxygen. These unburned gases will be discharged with the exhaust gas, which will result in energy waste. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a venturi tube structure for gas stoves.

[0006] The mixing assembly includes a mixing chamber located inside the housing. One end of the gas intake pipe is connected to two Venturi pipes, and the upper surface of the Venturi pipes has an outlet.

[0007] As a further description of the above technical solution:

[0008] Two mounting boxes are fixedly connected to the upper surface of the air intake pipe, and bolts pass through the interior of the mounting boxes.

[0011] As a further description of the above technical solution:

[0012] One of the mounting boxes has a first insert bracket inside, and the other mounting box has a second insert bracket inside. Both the first insert bracket and the second insert bracket have through holes inside, and the bolt passes through the through holes.

[0013] As a further description of the above technical solution:

[0014] A spiral blade is fixedly connected between the first and second inserts, and the spiral blade is positioned above the two air outlets.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the air intake pipe is provided with a filter assembly, which includes a mounting ring and is fixedly connected to the inner wall of the air intake pipe.

[0017] As a further description of the above technical solution:

[0018] The mounting ring has a filter screen connected to its internal threads, and a handle is fixedly connected to the lower surface of the filter screen.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the mixing component, places the gas outlet above the air inlet pipe, and uses a venturi pipe to transport the gas from the outlet. The relatively flat shape of the outlet helps to increase the pressure of the gas when it is released, which facilitates mixing with the incoming air.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As attached Figure 1-6 As shown, one embodiment of this utility model is provided: a gas stove venturi tube structure, including a shell 1, a plurality of protrusions 2 are fixedly connected to the outside of the shell 1, and mounting holes 3 are opened inside the protrusions 2 to facilitate the installation and connection of the shell 1. An air intake pipe 4 is connected through the lower surface of the shell 1, and a gas intake pipe 5 is connected through the side of the shell 1. A gas intake port 6 is opened inside the gas intake pipe 5, and a mixing component is provided inside the shell 1.

[0032] The mixing assembly includes a mixing chamber 7, which is located inside the housing 1. One end of the gas inlet pipe 5 is connected to two venturi pipes 8. The upper surface of the venturi pipes 8 is provided with an outlet 9 to facilitate the gas entering the interior of the mixing chamber 7.

[0033] As attached Figure 5As shown, two mounting boxes 10 are fixedly connected to the upper surface of the air intake pipe 4 for the installation of the first bracket 14 and the second bracket 15. A bolt 11 passes through the inside of the mounting box 10. One end of the bolt 11 is threaded with a nut 12 to facilitate locking the first bracket 14 and the second bracket 15. A silicone pad 13 is provided on one side of the nut 12. When the silicone elasticity is applied to one side of the mounting box 10 and deformed, the nut 12 can be tightened.

[0034] As attached Figure 6 As shown, one of the mounting boxes 10 has a first insert 14 inside, and the other mounting box 10 has a second insert 15 inside, which is convenient for insertion into the mounting box 10. Both the first insert 14 and the second insert 15 have through holes 17 inside for bolts 11 to pass through. The bolts 11 pass through the through holes 17. A spiral blade 16 is fixedly connected between the first insert 14 and the second insert 15 to guide the gas. The spiral blade 16 is located above the two gas outlets 9.

[0035] As attached Figure 3 As shown, the inner wall of the air intake pipe 4 is provided with a filter assembly, which includes a mounting ring 18 for easy threading. The mounting ring 18 is fixedly connected to the inner wall of the air intake pipe 4. The internal thread of the mounting ring 18 is connected to a filter screen 19. The outer ring of the filter screen 19 is threaded. The lower surface of the filter screen 19 is fixedly connected to a handle 20 for easy rotation of the filter screen 19.

[0036] Working principle: In use, connect the gas inlet pipe 5 to the external gas delivery pipe and the air inlet pipe 4 to the external air delivery pipe. Then, install the outer casing 1 before the mixed gas delivery pipe. When the gas is delivered, it enters through the gas inlet pipe 5 and the gas inlet port 6, reaching the Venturi pipe 8, where a negative pressure is formed. The gas exits through the outlet port 9 of the Venturi pipe 8 and then reaches the interior of the mixing chamber 7. At the same time, the air inlet pipe 4 delivers air into the mixing chamber 7, causing the air to mix with the gas. Simultaneously, the air and gas flow through the spiral blades 16. Under the guidance of the spiral, the spiral moves and mixes, which helps to improve the uniformity of the air and gas mixture. When the spiral blade 16 does not need to be installed, the nut 12 is used to pull the silicone pad 13 off the external thread of the bolt 11 by unscrewing. Then the bolt 11 is slid out from one side of the mounting box 10 and the inside of the through hole 17, so that the first bracket 14 and the second bracket 15 are released from the limit of the mounting box 10. The spiral blade 16 is moved up, which drives the first bracket 14 and the second bracket 15 to slide out from the inside of the mounting box 10, thereby removing the spiral blade 16.

[0037] When air is intake, it is filtered through filter screen 19 to block particles in the air. When filter screen 19 begins to become clogged, grasp and turn handle 20 so that handle 20 drives filter screen 19 to be unscrewed from the inside of mounting ring 18, thereby facilitating the removal and cleaning of filter screen 19.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
