Description

Technical Field

[0001] The invention relates to the technical field of gas stove valve bodies, in particular to a flat-plate ultra-thin safety valve with an angle. Background Art

[0002] A gas stove refers to a kitchen appliance that uses liquefied petroleum gas (liquid), artificial coal gas, natural gas and other gas fuels for direct fire heating. A gas stove is also called a gas stove, stove plate, stove top and stove. Its popularity is well known to everyone, but it is difficult to see a common concept. 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.

[0003] At present, the use of gas stoves is inseparable from the use of gas stove switch valve bodies. The gas stove switch valve body is a component used to turn on and off the gas stove and control the size of the fire. However, the existing gas stove switch valve body has a complex structure and a large size. At the same time, the knob must be pressed down to ignite the fire. If it is released halfway, the fire will not burn, which is time-consuming and laborious. Secondly, it is not convenient to adjust the air volume during the transfer. It takes a lot of time to try to make the flame reach the best blue combustion effect. Therefore, a flat-plate ultra-thin safety valve with an angle is proposed to solve the above problem. Summary of the invention

[0004] 1. Technical issues to be resolved

Secondly, it is inconvenient to adjust the air volume during conversion, and a lot of time and effort is required to make the flame achieve the optimal blue combustion effect.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1In this embodiment, a flat-plate ultra-thin safety valve with an angle includes an adjusting mechanism 1 and a burner air inlet pipe 2 located above the adjusting mechanism 1. Two gas distribution pipes 201 are arranged on the burner air inlet pipe 2. An ignition knob 3 for controlling the burner air inlet pipe 2 is installed below the adjusting mechanism 1. A solenoid valve 4 is connected to one end of the burner air inlet pipe 2. The connection between the burner air inlet pipe 2 and the solenoid valve 4 can be integrally formed, and the lower end of the solenoid valve 4 is in contact with the adjusting mechanism 1. A valve body air inlet 402 is arranged on the outside of the solenoid valve 4, which solves the problem of large air pressure loss caused by conventional multi-channel conversion air intake. A damper regulator 5 is mounted on the air outlet end of the burner air inlet pipe 2 to adjust the air volume.

[0028] Among them, the air door regulator 5, the stove head air inlet pipe 2, the regulating mechanism 1, the solenoid valve 4 and the ignition knob 3 are all installed on the same plane with a tilt angle of zero, and the structure is ultra-thin, saving space.

[0029] See also Figure 2-3 The regulating mechanism 1 includes a shell 101 located below the burner air inlet pipe 2 and a cam 102 located inside the shell 101. A hollow cavity opening upward is formed in the shell 101, and the hollow cavity is used for movably installing the cam 102, so that the cam 102 can rotate inside the shell 101 through the hollow cavity. A valve stem 103 penetrating the shell 101 is connected to the lower surface of the cam 102, and a fitting groove 104 is provided at one end of the valve stem 103 away from the cam 102. A sleeve 301 adapted to the valve stem 103 is formed inside the ignition knob 3, which can be mounted on the outside of the valve stem 103. At the same time, a plug plate 302 adapted to the fitting groove 104 is formed in the sleeve 301, so that when the sleeve 301 is mounted on the outside of the valve stem 103, the plug plate 302 is inserted into the fitting groove 104 to complete the clamping, thereby using the ignition knob 3 to rotate the cam 102.

[0030] Among them, the interior of the solenoid valve 4 is provided with a switch contact 401, and the switch contact 401 extends to the interior of the hollow cavity of the shell 101. The outer wall of the cam 102 is connected to the inclined block 105, and the upper surface of the inclined block 105 is inclined from bottom to top, so that when the valve stem 103 is rotated to drive the cam 102 to rotate, the inclined block 105 can be used to support the switch contact 401 until the temperature reaches the self-priming of the solenoid valve 4. When the solenoid valve 4 is in a fully opened and closed state, the ignition knob 3 will automatically reset and rotate upward, which ensures the normal operation of the valve and makes the performance more stable. At the same time, when using the inclined block 105, there is no need to continuously press down the ignition knob 3 to control the switch of the solenoid valve 4, which is simple and labor-saving.

[0031] One end of the burner air inlet pipe 2 connected to the shell 101 is connected with a closing plate 202 for sealing the opening above the shell 101. The closing plate 202 is provided with a threaded hole. The outside of the shell 101 is provided with a through tube 106. The through tube 106 is penetrated by a mounting screw 107 threadedly connected to the threaded hole, thereby completing the connection between the shell 101 and the burner air inlet pipe 2.

[0032] See also Figure 4-5 The air flap regulator 5 includes a fixed air flap 501 mounted on the two air distribution pipes 201 and two movable air flaps 502, wherein the fixed air flap 501 is composed of two circular air flaps, and the movable air flap 502 is composed of two fan-shaped air flaps. The centers of the fixed air flap 501 and the movable air flap 502 are both provided with a through hole 503, so that the fixed air flap 501 and the movable air flap 502 are mounted on the two air distribution pipes 201 through the through hole 503, and the movable air flap 502 is arranged below the fixed air flap 501, and the fixed air flap 501 is provided with four air slots 503. 4, two of them form a group and are respectively located on both sides of the through hole 503 for the passage of wind. The two air flaps of the fixed air flap 501 are both provided with scale gears 505, and the number of gears is ten. The movable air flap 502 is fixedly connected with an adjusting handle 506, so that the movable air flap 502 can be rotated under the fixed air flap 501 by adjusting the handle 506, so that the fan-shaped air flap can cover the air slot 504, and then adjust the size of the air volume. At the same time, referring to the scale gear 505, the effect of precise adjustment can be achieved when the gas cooker is assembled, so that the flame can achieve the best blue combustion effect.

[0033] In addition, an integrally formed protrusion 507 is provided on one side of the adjustment handle 506 close to the fixed air flap 501, and a latching hole 508 engaged with the protrusion 507 is formed on the fixed air flap 501. The number of the latching holes 508 is the same as the scale of the scale gear position 505, so that when the adjustment handle 506 is rotated, the protrusion 507 is engaged with the latching hole 508 to generate a rebound, which can make the gear position adjustment more precise.

[0034] When in use, the ignition knob 3 is pressed to rotate, thereby controlling the valve stem 103 and the cam 102 to rotate in the housing 101, and the solenoid valve 4 is opened by the interference between the inclined block 105 and the switch contact 401. At this time, there is no need to press the ignition knob 3 for a long time, so that the gas enters the burner inlet pipe 2 and ignites. At the same time, by using the slope of the inclined block 105, when the solenoid valve 4 is in a fully opened and closed state, the ignition knob 3 will automatically reset and rotate upward, that is, to ensure the normal operation of the valve;

[0035] During assembly, the movable air flap 502 can be rotated under the fixed air flap 501 by adjusting the handle 506, and then the air volume can be adjusted by covering the air slot 504. The scale gear 505 is convenient for accurately adjusting the covering area, so as to achieve the effect of quickly adjusting to the best blue combustion state.
