The air intake methods of gas stoves are divided into upper air intake, lower air intake, full air intake, etc., and can be divided into multiple types according to different classification standards. According to the gas source, gas stoves are mainly divided into liquefied gas stoves, coal gas stoves, and natural gas stoves. According to the stove eyes, they are divided into single stoves, double stoves and multi-burner stoves. During the use of gas stoves, a filling valve is required. The filling valve is a valve that closes the system from the outside world. A filling valve cap is installed on the filling valve.

[0003] When the current filling valve cap is connected to the filling valve control, several sets of sealing rings are arranged inside the valve cap to block the gap between the valve port and the outside. This operation is convenient and quick. However, when the valve cap is unscrewed and tightened, the internal thread groove will wear, resulting in a gap between the sealing ring and the thread groove, causing external air to enter the interior of the filling valve.

[0004] Therefore, it is particularly important to improve the existing filling valve bonnet and design a new filling valve bonnet to solve the above technical defects and improve the practicability of the overall filling valve bonnet. Utility Model Content

[0021] Example:

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] A filling valve cap comprises a valve cover 1, the outer surface of the valve cover 1 is provided with anti-skid patterns, the anti-skid patterns are distributed at equal intervals, a reinforcing ring 2 is fixedly connected to the bottom of the valve cover 1, an inner cover 3 is plugged and connected to the inner side of the valve cover 1, a fixing frame 4 is fixedly connected to the top of the valve cover 1, support rods 5 are fixedly connected to the left and right ends of the top of the fixing frame 4, a barrier strip 6 is fixedly connected to the top of the support rod 5, a limiting rod 7 is slidably connected to the middle of the fixing frame 4, a rubber plug 8 is fixedly connected to the bottom of the limiting rod 7, a first sealing ring 9 is fixedly sleeved on the outside of the rubber plug 8, and a first sealing ring 9 is fixedly sleeved on the outside of the rubber plug 8. The valve cover 1 is sleeved on the outside of the valve port. By rotating the valve cover 1 and through the design of anti-slip grooves, the friction between the hand and the anti-slip grooves is increased, and the valve cover 1 can be easily tightened and loosened, so that the inner cover 3 can tightly wrap the outside of the valve port, greatly improving its sealing performance, and squeezing the limit rod 7 downward to allow the rubber plug 8 to enter the inside of the valve port. The soft material of the rubber plug 8 fits tightly with the inner wall of the valve port, and the first sealing ring 9 is used to increase the anti-slip performance between the inner wall of the valve port and the rubber plug 8 to prevent the rubber plug 8 from shifting due to gas expansion.

[0024] For further information, see Figure 1 and Figure 2In this embodiment, the outside of the limiting rod 7 is slidably connected to a blocking ring 10, and a first spring 11 is sleeved on the outside of the limiting rod 7 and between the blocking ring 10 and the fixing frame 4. The top of the blocking strip 6 is fixedly connected to an elastic sheet 12. The limiting rod 7 extends to the outside of the elastic sheet 12. When the limiting rod 7 moves downward, it is limited by the fixing frame 4 and the elastic sheet 12, so that the limiting rod 7 moves along a predetermined route when it descends, thereby completing the precise insertion of the rubber plug 8 into the inside of the valve port.

[0025] For further information, see Figure 1 and Figure 2 The support rod 5 is fixedly connected with an auxiliary handle 13 on the outside, and a separator 14 is fixedly connected with the bottom of the auxiliary handle 13. The outer part of the separator 14 is symmetrically rotatably connected with a pressing handle 15. The pressing handle 15 is fixedly connected with an extrusion rod 16 on the inside of the end away from the auxiliary handle 13. The extrusion rod 16 is adapted for use with the barrier ring 10. The ends of the auxiliary handle 13 and the pressing handle 15 away from each other are coated with anti-slip particles. The operator holds the auxiliary handle 13 and the pressing handle 15 and pinches the pressing handle 15 to realize the upward movement of the right end of the pressing handle 15 and the downward movement of the left end of the pressing handle 15, so that the extrusion rod 16 squeezes the barrier ring 10, thereby completing the compression of the first spring 11, driving the limit rod 7 to press down, and then releasing the pressing handle 15 to realize the expansion and contraction of the first spring 11 and the energy storage to achieve reset, and then applying pressure to the pressing handle 15 again. The operation is repeated to realize the gradual downward movement of the limit rod 7.

[0026] For further information, see Figure 1 and Figure 2 In this embodiment, a second spring 17 is sleeved on the outside of the limit rod 7 and between the elastic sheet 12 and the barrier strip 6. A recessed block is symmetrically provided on the outside of the limit rod 7. A barrier pad is fixedly connected to the inside of the fixing frame 4 at a position corresponding to the recessed block. When the first spring 11 is reset, the limit rod 7 is fixed by the design of the second spring 17 and the elastic sheet 12 to prevent the limit rod 7 from moving upward when the first spring 11 is reset, and the barrier pad can increase the friction between the outside of the limit rod 7 and the fixing frame 4. When the valve cover 1 is opened, the limit rod 7 is pulled upward to enable the rubber plug 8 to leave the inside of the valve port.

[0027] For further information, see Figure 1 and Figure 3In this embodiment, a thread groove is provided on the inner wall of the inner cover 3, and a clamping groove 18 is provided on the inner wall of the valve cover 1. The inner cover 3 is plugged and unpluggedly connected to the valve cover 1 through the clamping groove 18. A second sealing ring 19 is fixedly connected to the inner cover 3 at a position close to the clamping groove 18. By rotating the valve cover 1, the thread groove and the external thread of the valve port are connected, and the valve cover 1 and the inner cover 3 are rotated and pressed down, so that the inner cover 3 wraps the valve port. The valve port will exert an outward expansion force on the inner cover 3, so that the second sealing rings 19 are pressed against each other, thereby further improving the sealing performance.

[0028] For further information, see Figure 1 and Figure 3 In this embodiment, a guide block 20 is symmetrically fixedly connected to the top of the inner side of the inner cover 3, a third sealing ring 21 is fixedly connected to the inside of the inner cover 3, an extension plate 22 is fixedly connected to the inside of the inner cover 3 and located at the bottom of the third sealing ring 21, a damping block 23 is provided on the inner side wall of the extension plate 22, and the guide block 20 is designed to be inclined so that the guide block 20 can buckle the top of the valve port, and the extension plate 22 is inserted into the inside of the clamping groove 18 to realize the synchronous rotation of the inner cover 3 and the valve cover 1, and the air between the third sealing ring 21 and the outside of the valve port is sealed, and the damping block 23 makes the air between the extension plate 22 and the clamping groove 18 compressed when the valve port squeezes the inner cover 3.

[0029] In this embodiment, the implementation scenario is specifically as follows: by sleeve-mounting the valve cover 1 on the outside of the valve port, by rotating the valve cover 1, and by the design of the anti-slip pattern, the friction between the hand and the anti-slip pattern is increased, the thread groove and the external thread connection of the valve port are realized, the valve cover 1 and the inner cover 3 are rotated and pressed down, the inner cover 3 wraps the valve port, and the guide block 20 buckles the top of the valve port. The valve port will exert an outward expansion force on the inner cover 3, so that the second sealing ring 19 presses against each other, and the air between the outside of the valve port is sealed by the third sealing ring 21. The operator holds the auxiliary handle 13 and the pressing handle 15 and squeezes the pressing handle 15, so that the right end of the pressing handle 15 moves upward and the left end of the pressing handle 15 moves downward, so as to achieve squeezing. The pressure rod 16 squeezes the barrier ring 10, thereby completing the compression of the first spring 11, driving the limit rod 7 to press down, and then releasing the pressing handle 15 to realize the expansion and contraction energy storage of the first spring 11 to achieve reset, and applying pressure to the pressing handle 15 again, and repeating the operation to realize the gradual decline of the limit rod 7. The limit rod 7 is fixed by the design of the second spring 17 and the elastic sheet 12 to prevent the limit rod 7 from moving upward when the first spring 11 is reset, and the barrier pad can increase the friction between the outside of the limit rod 7 and the fixing frame 4, so that the rubber plug 8 can enter the inside of the valve port, and the soft material of the rubber plug 8 fits tightly with the inner wall of the valve port, and the first sealing ring 9 increases the anti-slip property between the inner wall of the valve port and the rubber plug 8 to prevent the rubber plug 8 from shifting due to gas expansion.
