[0024] like Figure 1 - Figure 5 As shown, the gas stove burner with good airtightness in the utility model is similar to the existing gas stove burner with good airtightness, such as a gas stove burner disclosed in the patent with announcement number CN211060180U. The main improvement of the utility model is to reduce the influence of oil pollution on the connection between the gas stove burner 1 and the fire cover 2, and improve the sealing of the installation position of the burner and the fire cover 2. Figures 1 to 5As shown, when the gas stove burner with good airtightness in the utility model is in use, the fire cover 2 is first installed above the gas burner 1, and then the first annular oil baffle plate 3 is put on the gas burner 1, and at the same time, the gap at the connection between the gas burner 1 and the fire cover 2 is blocked, and the top of the first annular oil baffle plate 3 is ensured to be located below the fire hole 201 on the fire cover 2, so as to avoid the first annular oil baffle plate 3 blocking the fire hole 201 and affecting the gas ignition. During use, when splashed oil drips onto the gas burner 1, it will be blocked on the outside by the first annular oil baffle plate 3, so as to avoid the oil from contacting the gas burner 1 and the gap position where the fire cover 2 and the gas burner 1 are connected, thereby avoiding the high temperature from causing the oil to agglomerate and affecting the sealing of the connection between the fire cover 2 and the gas burner 1, further improving the airtightness during the use of the burner, reducing the possibility of gas leakage from the connection between the gas burner 1 and the fire cover 2, and improving the safety of the use of the gas burner 1.

[0025] like Figure 1 - Figure 5 As shown, the outer wall of the gas burner head 1 at one end away from the fire cover 2 is connected with a positioning ring 4, the positioning ring 4 is sleeved with the gas burner head 1 and fixedly connected thereto, the end of the first annular oil baffle plate 3 away from the fire cover 2 is connected with a telescopic component, the other end of the telescopic component is connected to the positioning ring 4, and the inner wall of the first annular oil baffle plate 3 is slidably connected with the outer walls of the gas burner head 1 and the fire cover 2. By setting the telescopic component, the first annular oil baffle plate 3 is installed above the positioning ring 4, so that the first annular oil baffle plate 3 can slide up and down on the outer walls of the gas burner head 1 and the fire cover 2, so that when installing the fire cover 2, the first annular oil baffle plate 3 can be pressed downward to facilitate the installation of the fire cover 2, and after the fire cover 2 is installed, the first annular oil baffle plate 3 can be driven to automatically rise through the telescopic component, so as to cover the connection between the gas burner head 1 and the fire cover 2.

[0026] like Figure 1 - Figure 5 As shown, the telescopic assembly includes a plurality of telescopic springs 5, the same end of which is fixedly connected to the side of the positioning ring 4 close to the fire cover 2, and the other end is fixedly connected to the side of the first annular oil baffle plate 3 away from the fire cover 2, and the plurality of telescopic springs 5 ​​are evenly and equidistantly distributed along the ring wall of the positioning ring 4. By distributing a plurality of telescopic springs 5 ​​on the positioning ring 4, the entire bottom of the first annular oil baffle plate 3 can be lifted at the same time, so that the first annular oil baffle plate 3 can slide up and down more stably and smoothly.

[0027] like Figure 1 - Figure 5As shown, the outer wall of the first annular oil baffle plate 3 away from the fire cover 2 is connected with the second annular oil baffle plate 6, the second annular oil baffle plate 6 is sleeved with the first annular oil baffle plate 3 and fixedly connected thereto, and the second annular oil baffle plate 6 is also sleeved with the positioning ring 4 at one end away from the first annular oil baffle plate 3 and is slidably connected with the positioning ring 4. By fixing the second annular oil baffle plate 6 on the outer wall at the bottom of the first annular oil baffle plate 3, the telescopic spring 5 at the bottom of the first annular oil baffle plate 3 is shielded inside, thereby preventing the oil splashed on the first annular oil baffle plate 3 from dripping down onto the telescopic spring 5, affecting the telescopic elasticity of the telescopic spring 5, and improving the stability of the telescopic spring 5.

[0028] like Figure 1 - Figure 5 As shown, the outer ring wall of the first annular oil baffle plate 3 near one end of the fire cover 2 is an arc surface. The outer wall of the top of the first annular oil baffle plate 3 is designed as an arc surface, so that the oil splashed on the top of the first annular oil baffle plate 3 can flow downward more smoothly, avoiding the accumulation of oil on the top of the first annular oil baffle plate 3 and causing the top of the first annular oil baffle plate 3 to adhere to the fire cover 2.

[0029] like Figure 1 - Figure 5 As shown, one end of the first annular oil baffle plate 3 close to the telescopic spring 5 is fixedly connected with a plurality of limiting rods 7, and one end of the plurality of limiting rods 7 away from the first annular oil baffle plate 3 respectively penetrates the plurality of telescopic springs 5 ​​and the positioning ring 4, and is slidably connected with the positioning ring 4. When the first annular oil baffle plate 3 is pressed downward, the telescopic spring 5 is compressed on the limiting rod 7, which can prevent the telescopic spring 5 from being twisted and deformed when being compressed, thereby improving the stability of the telescopic spring 5.

[0030] like Figure 1 - Figure 5 As shown, the end of the limit rod 7 away from the first annular oil baffle plate 3 is fixedly connected with an anti-slip block 8, and the side of the anti-slip block 8 close to the limit rod 7 abuts against the side of the positioning ring 4 away from the first annular oil baffle plate 3. After pressing the first annular oil baffle plate 3 and installing the fire cover 2 on the gas burner head 1, the first annular oil baffle plate 3 is loosened, and at this time, multiple telescopic springs 5 ​​lift the first annular oil baffle plate 3 upward. Through the action of the anti-slip block 8 and the limit rod 7, the first annular oil baffle plate 3 rises to the bottom of the fire hole 201 and stops rising, limiting the first annular oil baffle plate 3 below the fire hole 201 to prevent the first annular oil baffle plate 3 from blocking the fire hole 201.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
