Description

TECHNICAL FIELD

The present disclosure relates to the technical field of ignition tools, and in particular, to an igniter capable of monitoring a gas output of gas in real time.

BACKGROUND

Ignition guns generally include a pulse ignition gun and an open flame ignition gun. The pulse ignition gun uses a battery and is generally used on a gas stove in a kitchen. The open flame ignition gun uses butane gas and is commonly used in outdoor camping, barbecue, metal surface processing, partial heating and bending of plastic, glass burr edge finishing, small object processing and welding, and the like.

An existing gas igniter includes a gas storage tank, a mounting base, and a fire outlet mechanism. The mounting base is mounted on the gas storage tank. A gas channel for gas flowing is provided on the mounting base. A gas inlet of the gas channel is communicated with the gas storage tank, and a gas outlet of the gas channel is disposed forward. The mounting base is provided with a gas adjustment mechanism for adjusting opening and closing of the gas channel. The fire outlet mechanism includes a housing, a gas outlet pipe, and a piezoelectric igniter. The gas outlet pipe is fixedly mounted on the housing. An inlet of the gas outlet pipe corresponds to the gas outlet of the gas channel. The piezoelectric igniter is fixedly mounted on the mounting base. The mounting base is provided with a push switch for driving the piezoelectric igniter to work.

The above igniter opens the gas channel by operating the gas adjustment mechanism, so that gas flows to the gas outlet pipe of the housing. The push switch is operated for electrification and ignition. The gas adjustment mechanism can open or close the gas channel, and can further adjust a gas volume to control fire. However, all the existing igniters are unable to monitor a gas pressure inside the gas channel to ensure whether the gas pressure is within a safe range. When the gas pressure is too high, excessively large flame, backfire, and even equipment damage are caused. When the pressure is too low, an ignition failure or unstable flame occurs, and it fails in accurately adjusting the fire. Moreover, when the igniter malfunctions, a large troubleshooting range is required.

SUMMARY

A purpose of the present disclosure: to overcome the defects of the existing technology, the present disclosure provides an igniter capable of monitoring a gas output of gas in real time, so that an operator can observe a gas pressure inside a gas outlet channel in real time, so as to facilitate the adjustment and accurate control of fire and also facilitate the maintenance and fault diagnosis of the igniter.

A technical solution of the present disclosure is as follows: An igniter capable of monitoring a gas output of gas in real time includes a handheld portion and a body of a flame spraying portion. A gas adjustment member and an ignition member are disposed within the handheld portion. The gas adjustment member is provided with a gas inlet channel and a gas outlet channel. The gas outlet channel is communicated with the flame spraying portion through a gas outlet pipe. The body is provided with an adjustment rod. The adjustment rod is configured to: control connection and disconnection between the gas inlet channel and the gas outlet channel, and adjust the gas output. The body is further provided with a pressure gauge. A sensing head of the pressure gauge is disposed within the gas outlet channel or the gas outlet pipe to monitor a volume of gas flowing inside the gas outlet channel or the gas outlet pipe.

By using the above technical solution, the adjustment rod controls the connection and disconnection between the gas inlet channel and the gas outlet channel and the gas output, so that the gas can flow from the gas storage tank to the gas outlet pipe, and the ignition member can be pressed for electrification and ignition. By the arrangement of the pressure gauge, a real-time flow rate value of the gas in the gas outlet channel or the gas outlet pipe can be measured. Furthermore, the gas output can be accurately adjusted, and whether gas leakage exists can be monitored. When the igniter is not used, if gas is detected to exist in the gas outlet pipe or the gas outlet channel, it can check whether the gas leakage is caused because the adjustment rod does not completely cut off the connection between the gas inlet channel and the gas outlet channel or because the sealing performance is poor due to looseness of a sealing ring on the adjustment rod after prolonged use of the adjustment rod resulting in poor sealing. To prevent the gas from flowing out to cause air pollution, the sensing head of the pressure gauge is placed inside the gas outlet pipe or the gas outlet channel. Meanwhile, it is also convenient for the maintenance and fault diagnosis of the igniter. Whether there is still gas in the gas storage tank based on a pressure value, and whether an igniter fault is related to the gas storage tank can be quickly found out.

In a further setting of the present disclosure, a connection channel is further provided at a position, located at the gas outlet channel, on the gas adjustment member. The connection channel is communicated with the gas outlet channel. The pressure gauge is fixedly connected to the connection channel. The sensing head of the pressure gauge is located inside the connection channel or passes through the connection channel and is disposed within the gas outlet channel.

By using the above further setting, the pressure gauge is mounted in the connection channel communicated with the gas outlet pipe. This can reduce the interference of gas flow fluctuations and environmental factors, and enhance the measurement accuracy and the equipment durability. Meanwhile, it is also convenient for later maintenance, verification, and inspection. This protects the pressure gauge and can also ensure that a pressure monitoring result is more stable and reliable.

In a further setting of the present disclosure, the gas adjustment member is further provided with an adjustment channel communicated with the gas inlet channel and the gas outlet channel. The gas inlet channel, the adjustment channel, and the gas inlet channel are arranged in a T shape. The gas inlet channel and the adjustment channel are located on the same axis. An axis of the gas outlet channel is perpendicular to an axis of the gas inlet channel. An axis of the connection channel is perpendicular to the axis of the gas outlet channel and the axis of the gas inlet channel.

By using the above further setting, a resistance to fluid during turning can be reduced, generation of turbulent flow can be mitigated, and the gas flowing efficiency can be enhanced. The design in which the adjustment channel and the gas inlet channel are on the same axis makes the adjustment on the gas flow more direct and flexible. It helps to achieve accurate flow rate control, thus more easily maintaining uniform pressure distribution, and also helps to avoid local overpressure or underpressure situations, thus enhancing the system stability. A T-shaped structure can usually better use a limited space, so that the overall layout is more compact.

In a still further setting of the present disclosure, a front end of the adjustment rod is located inside the adjustment channel and is in threaded and sealed fit with the adjustment channel. An adjustment knob is mounted at a rear end of the adjustment rod. The adjustment knob is exposed out of the body.

By using the above still further setting, it is convenient to drive the adjustment rod to rotate. The rotation of the adjustment rod within the adjustment channel can control the connection or disconnection between the gas inlet channel and the gas outlet channel and the gas volume. A sealing element is arranged on the adjustment rod to ensure a good sealing effect and avoid gas leakage. The adjustment knob is located outside the body for easy operation.

In a still further setting of the present disclosure, the body is further provided with a connection portion. The connection portion is located between the handheld portion and the flame spraying portion. The gas adjustment member is mounted inside the connection portion.

By using the above still further setting, the connection portion and the handheld portion are integrally formed. The flame spraying portion is located at a front end of the connection portion and the handheld portion is located at a rear end of the connection portion. This can more directly control a flow rate of gas entering the flame spraying portion, so that a user can conveniently and quickly adjust the flow rate of the gas to meet different application needs.

In a still further setting of the present disclosure, the body includes a left shell and a right shell that are separately arranged. Positioning plates are arranged on inner side walls of the left shell and the right shell. The positioning plates are provided with arc-shaped slots adapting to the gas adjustment member. An extension sheet is arranged on an outer side wall of the gas adjustment member. The left shell is provided with a connection column. The extension sheet is connected to the connection column through a screw. The connection channel extends towards the right shell.

By using the above still further setting, the separate design facilitates the mounting, the removal, and the replacement of the components inside the body. The two shells are connected through the screw, and the arc-shaped slots clamp and position the gas adjustment member, making the structure of the gas adjustment member stable. The mounting and removal of the gas adjustment member through the screw are convenient and quick, and have good firmness.

As shown in FIGS. 1-6, an igniter capable of monitoring a gas output of gas in real time includes a body 1 with a handheld portion 11 and a flame spraying portion 12. The handheld portion 11 is provided with a gas adjustment member 2 and an ignition member 3. The gas adjustment member 2 is provided with a gas inlet channel 21 and a gas outlet channel 22. The gas outlet channel 22 is communicated with the flame spraying portion 12 through a gas outlet pipe 4, and the ignition member 3 employs a piezoelectron. A lead of the ignition member extends into the flame spraying portion 12 and is located on one side of the gas outlet pipe 4. The ignition member 3 can be provided with a push switch 31. The push switch 31 is exposed outside the handheld portion 11. By operating the push switch 31, the ignition member 3 can be triggered, or the ignition member 3 can be directly pressed. The main body 1 is provided with an adjustment rod 5. The adjustment rod 5 is configured to: control connection and disconnection between the gas inlet channel 21 and the gas outlet channel 22 and adjust the gas output. The adjustment rod 5 is provided with a sealing element. the sealing element uses a sealing ring to ensure a good sealing effect and avoid gas leakage. A sensing head of the pressure gauge responds to a pressure change through elastic deformation (such as displacement of a diaphragm, a corrugated pipe, or a spring tube), and transmits this change to an indication mechanism (such as pointer) or an electronic conversion circuit, thereby displaying or transmitting a pressure value. In a traditional mechanical pressure gauge, the sensing head is mostly a metal diaphragm or a spring tube. In a smart pressure gauge, the sensing head is integrated with an electronic sensor (such as a piezoresistive or capacitive sensor) which supports a wireless transmission function. The body 1 is provided with a pressure gauge 6, and a sensing head of the pressure gauge 6 is placed inside the gas outlet channel 22 or the gas outlet pipe 4 to monitor a volume of gas flowing in the gas outlet channel 22 or the gas outlet pipe 4. The adjustment rod 5 controls the connection and disconnection between the gas inlet channel 21 and the gas outlet channel 22 and the gas output, so that the gas can flow from the gas storage tank to the gas outlet pipe 4, and the ignition member 3 can be pressed for electrification and ignition. By the arrangement of the pressure gauge 6, a real-time flow rate value of the gas in the gas outlet channel 22 or the gas outlet pipe 4 can be measured. Furthermore, the gas output can be accurately adjusted, and whether gas leakage exists can be monitored. When the igniter is not used, if gas is detected to exist in the gas outlet pipe or the gas outlet channel, it can check whether the gas leakage is caused because the adjustment rod does not completely cut off the connection between the gas inlet channel and the gas outlet channel or because the sealing performance is poor due to looseness of a sealing ring on the adjustment rod after prolonged use of the adjustment rod resulting in poor sealing, so as to prevent the gas from flowing out to cause air pollution. Meanwhile, it is also convenient for the maintenance and fault diagnosis of the igniter. Whether there is still gas in the gas storage tank based on a pressure value, and whether an igniter fault is related to the gas storage tank can be quickly found out. The body 1 is connected to the gas storage tank and can be mounted through threaded fit, so that the mounting is convenient. The gas storage tank can be configured as a cylindrical structure for easy grasping operation. A specific structure of the gas storage tank belongs to the existing technology. The present disclosure does not improve the gas storage tank, so it will not be described in detail. As not shown in the accompanying drawings of the present disclosure, a plurality of through holes can be formed in a rear end surface of the flame spraying portion 12 for entry of external air.

A connection channel 23 is further provided at a position, located at the gas outlet channel 22, on the gas adjustment member 2. The connection channel 23 is communicated with the gas outlet channel 22. The pressure gauge 6 is fixedly connected to the connection channel 23. The sensing head of the pressure gauge 6 is located inside the connection channel 23 or passes through the connection channel 23 and is disposed within the gas outlet channel 22. The pressure gauge (6) is mounted inside the connection channel 23 communicated with the gas outlet channel 22. This can reduce the interference of gas flow fluctuations and environmental factors, and enhance the measurement accuracy and the equipment durability. Meanwhile, it is also convenient for later maintenance, verification, and inspection. This protects the pressure gauge and can also ensure that a pressure monitoring result is more stable and reliable. The gas adjustment member 2 is further provided with an adjustment channel 24 communicated with the gas inlet channel 21 and the gas outlet channel 22. The gas inlet channel 21, the adjustment channel 24, and the gas inlet channel 22 are arranged in a T shape. The gas inlet channel 21 and the adjustment channel 24 are located on the same axis. An axis of the gas outlet channel 22 is perpendicular to an axis of the gas inlet channel 21. An axis of the connection channel 23 is perpendicular to the axis of the gas outlet channel 22 and the axis of the gas inlet channel 21. This can reduce a resistance to fluid during turning, generation of turbulent flow can be mitigated, and the gas flowing efficiency can be enhanced. The design in which the adjustment channel 24 and the gas inlet channel 21 are on the same axis makes the adjustment on the gas flow more direct and flexible. It helps to achieve accurate flow rate control, thus more easily maintaining uniform pressure distribution, and also helps to avoid local overpressure or underpressure situations, thus enhancing the system stability. A T-shaped structure can usually better use a limited space, so that the overall layout is more compact. A front end of the adjustment rod 5 is located inside the adjustment channel 24 and is in threaded and sealed fit with the adjustment channel 24. An adjustment knob 51 is mounted at a rear end of the adjustment rod 5. It is convenient to drive the adjustment rod 5 to rotate. The rotation of the adjustment rod 5 within the adjustment channel 24 can control the connection or disconnection between the gas inlet channel 21 and the gas outlet channel 22 and the gas volume.

The body 1 is further provided with a connection portion 16. The connection portion 16 is located between the handheld portion 11 and the flame spraying portion 12. The gas adjustment member 2 is mounted inside the connection portion 16. The connection portion 16 and the handheld portion 11 are integrally formed. The flame spraying portion 12 is located at a front end of the connection portion 16 and the handheld portion 11 is located at a rear end of the connection portion 16. This can more directly control a flow rate of gas entering the flame spraying portion, so that a user can conveniently and quickly adjust the flow rate of the gas to meet different application needs. The adjustment knob 51 is exposed out of the connection portion 16.

The body 1 includes a left shell 13 and a right shell 14 that are separately arranged. It is convenient to mount, remove, and replace components inside the body 1, and the two shells are connected through a screw. Specifically, for the mounting of the gas adjustment member 2, positioning plates 15 are arranged on inner side walls of the left shell 13 and the right shell 14. The positioning plates 15 are provided with arc-shaped slots adapting to the gas adjustment member 2. An extension sheet 25 is arranged on an outer side wall of the gas adjustment member 2. The left shell 13 is provided with a connection column 131. The extension sheet 25 is connected to the connection column 131 through a screw. The connection channel 23 extends towards the right shell 14. The arc-shaped slots clamp and position the gas adjustment member 2, making the structure of the gas adjustment member stable. The mounting and removal of the gas adjustment member 2 through the screw are convenient and quick, and have good firmness. Meanwhile, the internal structural layout of the body 1 is proper and will not affect the mounting of the pressure gauge 6.

A piezoelectron is a commonly used structure in an ignition tool. The piezoelectron is arranged at a rear end portion of the handheld portion 11. The handheld portion 11 is provided with an electronic wire pipeline. One end of the electronic wire of the piezoelectron is connected to the piezoelectron, and another end is located inside the electronic wire pipeline, extends into the flame spraying portion 12, and is located on one side of the gas outlet pipe 4. The electronic wire pipeline is parallel to the gas outlet pipe 4 and is spaced apart from the gas outlet pipe by a distance to prevent heat transfer from causing the temperature of the electronic wire pipeline to be too high, which may affect the use and lifespan of an internal electronic wire. When the igniter is activated, the gas enters the gas outlet channel from the gas storage tank, and then enters the gas outlet pipe 4. A through hole is formed in the flame spraying portion 12 for entry of the external air. The ignition member 3 is activated to spark an electronic wire at the flame spraying portion 12, to generate flames.
