Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stove nozzle technology, and in particular to a gas stove nozzle assembly. Background Technology
[0002] Among the core components of a gas stove, the nozzle assembly plays a crucial role in gas delivery and initial air mixing. Its performance directly affects the gas stove's combustion efficiency, safety, and ease of maintenance.
[0003] Existing devices are difficult to clean when the filter holes are clogged. Current filter structures are mostly fixed and integrated, requiring special tools for disassembly and cleaning after the filter holes become clogged. This process is complex and can easily damage the sealing structure, leading to gas leaks. Furthermore, the backfire protection mechanism is insufficient. The temperature sensor solution at the bottom of the burner has a delayed response and cannot directly block the spread of flames. The one-way valve solution inside the nozzle has low reliability due to the need for additional assembly and the rigid structure being prone to jamming. This poses safety hazards such as gas pipeline explosions and component burnout. To overcome these disadvantages, this utility model provides a gas stove nozzle assembly. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas stove nozzle assembly.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas stove nozzle assembly, including a connecting pipe, a connecting ring disposed inside the connecting pipe, a nozzle body slidably connected to the connecting ring and located inside the connecting pipe, a filter assembly disposed on one side of the connecting ring and located inside the connecting pipe, a cleaning assembly disposed on one side of the connecting ring and located inside the connecting pipe, a connecting frame fixedly connected inside the nozzle body, an anti-backfire assembly disposed on one side of the connecting frame, and a slide rail fixedly connected inside the connecting pipe, with the slide rail and the connecting ring slidably connected.
[0006] Furthermore, the filter assembly includes a filter tube fixedly connected to one side of the connecting ring and inside the connecting tube, and the filter tube has a plurality of filter holes fixedly connected to it.
[0007] Furthermore, the cleaning assembly includes a first spring fixedly connected to one side of the connecting ring and inside the connecting tube, a sliding plate fixedly connected to the nozzle body, the sliding plate being slidably connected to the inside of the connecting tube, and one side of the sliding plate being fixedly connected to one end of the first spring.
[0008] Furthermore, a sealing ring is fixedly connected to one side of the skateboard.
[0009] Furthermore, the backfire prevention assembly includes a second spring fixedly connected to one side of the connecting frame, and a sealing plate is fixedly connected to one end of the second spring.
[0010] Furthermore, the connecting pipe has internal threads.
[0011] The beneficial effects of this utility model are:
[0012] When using this utility model,
[0013] 1. By cooperating with the first spring and the sliding plate in the cleaning assembly, when the filter holes on the filter tube become clogged due to the accumulation of impurities over a long period of use, the operator only needs to block the air outlet of the nozzle body with his hand and then press down on the nozzle body. At this time, the nozzle body drives the sliding plate to slide along the inner wall of the connecting tube, which compresses the first spring. The internal space of the connecting tube shrinks and the air pressure increases. The high-pressure gas can quickly rush out from the filter holes of the filter tube, and the impurities blocking the filter holes are removed by the impact force of the airflow.
[0014] 2. Through the coordinated action of the second spring, sealing plate and connecting frame on the backfire prevention component, an automatic backfire prevention protection mechanism is formed. When backfire occurs in the gas stove, the flame will enter the nozzle body in the opposite direction, causing a reverse airflow in the nozzle body. This creates a significant pressure difference on both sides of the sealing plate. Driven by the pressure difference, the sealing plate will overcome the elasticity of the second spring and move upward until it tightly fits against the inner wall of the nozzle body's gas outlet, thereby quickly blocking the gas outlet channel of the nozzle body.

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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1-2 As shown, a gas stove nozzle assembly is disclosed, including a connecting pipe 1, a connecting ring 3 inside the connecting pipe 1, a nozzle body 2 slidably connected to the connecting ring 3 inside the connecting pipe 1, a filter assembly inside the connecting pipe 1 on one side of the connecting ring 3, a cleaning assembly inside the connecting pipe 1 on one side of the connecting ring 3, a connecting bracket 11 fixedly connected inside the nozzle body 2, an anti-backfire assembly on one side of the connecting bracket 11, and a slide rail 6 fixedly connected inside the connecting pipe 1, with the slide rail 6 and the connecting ring 3 slidably connected.
[0022] As shown in the figure, the filter assembly includes a filter tube 4 fixedly connected to one side of the connecting ring 3 and inside the connecting pipe 1. Several filter holes 5 are fixedly connected on the filter tube 4 for filtering impurities entering the nozzle.
[0023] As shown in the figure, the cleaning assembly includes a first spring 10 fixedly connected to one side of the connecting ring 3 and inside the connecting tube 1. A slide plate 8 is fixedly connected to the nozzle body 2. The slide plate 8 is slidably connected to the inside of the connecting tube 1. One side of the slide plate 8 is fixedly connected to one end of the first spring 10, which is used to remove impurities in the filter hole 5.
[0024] As shown in the figure, a sealing ring 9 is fixedly connected to one side of the slide plate 8 to seal the connection between the slide plate 8 and the connecting pipe 1, so as to prevent gas from leaking from the connection.
[0025] As shown in the figure, the backfire prevention assembly includes a second spring 12 fixedly connected to one side of the connecting frame 11. A sealing plate 13 is fixedly connected to one end of the second spring 12 to prevent backfire accidents.
[0026] As shown in the figure, the connecting pipe 1 has an internal thread 7, which is used to connect the device to the gas stove.
[0027] Working Principle: Before use, first check if the component is intact. After inspection, connect the device to the gas stove via the internal thread 7 on the connecting pipe 1. During use, gas enters the connecting ring 3 and passes through several filter holes 5 on the filter pipe 4 into the nozzle body 2. The filter holes 5 filter impurities in the gas, such as tiny particles and dust, preventing them from entering the nozzle body 2 with the gas. The gas is then sprayed out from the outlet of the nozzle body 2, mixing with air and achieving stable combustion at the burner, providing normal heat to the gas stove. After use or before each use, the operator can block the outlet of the nozzle body 2 with their hand and quickly press down on the nozzle body 2. Because the nozzle body 2 is slidably connected to the connecting ring 3 via the sliding plate 8, the nozzle body 2, under pressure, drives the sliding plate 8 to slide down along the inner wall of the connecting pipe 1. During the sliding process, the sliding plate 8 compresses the first spring 10 in the cleaning assembly, causing the first spring 10 to undergo elastic deformation. At this time, the volume of space in the connecting pipe 1 decreases, and the gas is sprayed out from the outlet. When the gas nozzle body 2's outlet is blocked by the operator, the internal airflow reverses and rushes out through the filter holes 5 of the filter tube 4. The impact force of the airflow washes away the impurities blocking the filter holes 5, thus clearing the filter holes 5. After cleaning, the operator releases their hand from the gas nozzle body 2's outlet. The first spring 10, under the action of elastic deformation, pushes the sliding plate 8 upward to reset, causing the nozzle body 2 to return to its initial position. When backfire occurs in the gas stove, the reverse flame and high-temperature airflow generated by the backfire enter the interior of the nozzle body 2, causing the airflow direction inside the nozzle body 2 to change. The reverse airflow creates a significant pressure difference on both sides of the sealing plate 13 in the backfire prevention assembly. Under the action of the pressure difference, the sealing plate 13 will overcome the elastic force of the second spring 12 and move upward until the sealing plate 13 tightly adheres to the inner wall of the nozzle body 2's outlet, thereby blocking the outlet of the nozzle body 2 and cutting off the channel for the backfire airflow to spread to the connecting pipe 1 and the external gas pipeline, preventing backfire from causing gas explosion in the connecting pipe 1 or fire in the external gas pipeline, and other safety accidents.
