In addition, a gas control valve 7 can be arranged at one end of the handle 3, which is close to the first gas outlet pipe 4, and the gas control valve 7 can be used for adjusting gas flow and controlling the size of flame.
To improve the reliability of the first air outlet pipe 4, referring to fig. 2, in one embodiment, the automatic ignition flame gun may further include a protection pipe 204, the protection pipe 204 is sleeved on the outer side of the first air outlet pipe 4, and an end of the first air outlet pipe 4 near the handle 3 extends out of the protection pipe 204, so as to facilitate the installation of the conical stand 201 and the flame switch 203.
In order to prevent backfire accidents during stopping operation, referring to fig. 2 and 3, fig. 3 is a schematic diagram illustrating a positional relationship between a toothed ring and an end cover according to an embodiment of the present application, in an embodiment, the automatic ignition flame gun may further include a gas storage tube 406, a toothed ring 505, a second gas outlet tube 506, a gas inlet tube 402, a ball valve 405, a first connecting rod 403, a sealer 303, a valve rod 302, and a hand wheel 301.
The gas storage tube 406 is sleeved on the outer side of the protection tube 204, and the gas storage space between the gas storage tube 406 and the protection tube 204 is blocked by the end cover 60, it is understood that the end cover 60 is an annular cover plate, so that the first gas outlet tube 4 passes through the annular cover plate to be connected with the nozzle 5. The end cap 60 is provided with a through hole 601. One end of the second air outlet pipe 506 is connected to the nozzle 5, and the other end is connected to the through hole 601. The toothed ring 505 is rotatably sleeved on the outer side of the protection pipe and is attached to the end cover 60 in the air storage space, namely, the toothed ring 505 is attached to the inner side surface of the end cover 60, and the toothed ring 505 is provided with air outlet holes 507 opposite to the through holes 601, so that the second air outlet pipe 506 is communicated with the air storage space. After the toothed ring 505 rotates by a first preset angle relative to the protection tube 204, the air outlet holes 507 are staggered from the through holes 601, so that the communication between the second air outlet pipe 506 and the air storage space can be blocked. It should be noted that the sizes of the air outlet holes 507 and the through holes 601 may be the same or different, so that the air outlet holes 507 and the through holes 601 can be communicated after the toothed ring 505 rotates by a certain angle. One end of the air inlet pipe 402 communicates with the air storage space, and the other end communicates with the air passage of the handle 3. A ball valve 405 is disposed in the inlet pipe 402 for allowing gas to enter from the inlet pipe 402 and flow into the gas storage space after rotating a second predetermined angle. One end of the first connecting rod 403 penetrates through the first air outlet pipe 4 and the air inlet pipe 402 to be connected with the ball valve 405, and is used for rotating the ball valve 405. The sealer 303 is disposed at one end of the first air outlet pipe 4 near the handle 3, and is configured to block the air from flowing from the first air outlet pipe 4 after rotating by a third preset angle. One end of the valve rod 302 penetrates through the side wall of the first air outlet pipe 4 and is connected with the sealer 303. A handwheel 301 is connected to the other end of the valve stem 302 for rotating the obturator 303 via the valve stem 302.
The working principle of the automatic ignition flame gun of the embodiment is as follows: when the operation needs to be stopped, the hand wheel 301 can be rotated, the hand wheel 301 drives the sealer 303 to rotate by a third preset angle through the valve rod 302, and the circulation of gas from the first air outlet pipe 4 is blocked, namely, the interior of the first air outlet pipe 4 is divided into two parts which are not communicated with each other through the sealer 303, so that the effects of blocking the transportation of liquefied gas and preventing backfire accidents caused by the backflow of the gas can be achieved, and the sealer 303 is preferably made of fireproof ceramic materials, so that the effect of thoroughly blocking is achieved. In addition, the ball valve 405 can be driven to rotate by controlling the first connecting rod 403 to a second preset angle, so that gas can enter from the gas inlet pipe 402 and flow into the gas storage space, and meanwhile, the toothed ring 505 is controlled to rotate by a first preset angle, so that the gas outlet holes 507 are staggered with the through holes 601 on the end cover 60, and the gas is blocked from flowing into the second gas outlet pipe 506 from the gas storage space. At this time, the gas in the hose 2 can flow into the gas storage space through the gas inlet pipe 402 to achieve the effect of gas storage, and at the same time, the excessive pressure in the hose 2 can be prevented. When the stored liquefied gas is continuously used, the stored liquefied gas can be reused, and waste is avoided.
Further, the present application also provides a structure for cooperative movement of the rotation of the obturator 303, the ball valve 405 and the toothed ring 505. Referring to fig. 2-5, fig. 4 is an enlarged schematic view of a portion C in fig. 1, and fig. 5 is a schematic view of a partial perspective view of an automatic ignition gun according to an embodiment of the present application. The auto-ignition gun of the present embodiment may further include a positioning plate 304, a stopper 305, a first flat gear 401, a second flat gear 404, a first bevel gear 501, a second connecting rod 502, a third flat gear 504, and a second bevel gear 503.
The positioning plate 304 is disposed on the valve rod 302 and is perpendicular to the valve rod 302, and when the valve rod 302 rotates, the positioning plate 304 is driven to rotate, for example, the positioning plate 304 and the valve rod 302 form a cross shape. The limiting frame 305 is disposed on an end of the outer wall of the first air outlet pipe 4, which is close to the valve rod 302, and is used for limiting the maximum rotation angle of the positioning plate 304 to be a third preset angle. Taking the third preset angle as 90 ° as an example, the limiting frame 305 may include two limiting portions located on the rotation track of the positioning plate 30, where one limiting portion blocks when the positioning plate 304 rotates 90 ° counterclockwise, and another limiting portion blocks when the positioning plate 304 rotates 90 ° clockwise. The positioning plate 304 and the limiting frame 305 limit that the sealer 303 can only rotate anticlockwise or clockwise by a third preset angle, thereby facilitating manual operation and reducing operation difficulty.
The first flat gear 401 is sleeved on the outer side of the valve rod 302, and the second flat gear 404 is connected to the other end of the first connecting rod 403 and is meshed with the first flat gear 401. The first flat gear 401 rotates along with the valve rod 302, and drives the ball valve 405 to rotate by a second preset angle through the second flat gear 404 and the first connecting rod 403, so as to control the circulation and blocking of the gas from the gas inlet pipe 402. That is, when the valve rod 302 rotates by the third preset angle, the ball valve 405 can be just driven to rotate by the second preset angle, and the relationship between the second preset angle and the third preset angle can be designed according to the transmission ratio of the first flat gear 401 and the second flat gear 404.
The first bevel gear 501 is sleeved outside the valve rod 302, the second connecting rod 502 is in the air storage space and extends out from one end close to the valve rod 302, the third flat gear 504 is sleeved outside the second connecting rod 502 in the air storage space and meshed with the toothed ring 505, and the second bevel gear 503 is sleeved outside one end of the second connecting rod 502 in the air storage space and meshed with the first bevel gear 501. The first bevel gear 501 rotates along with the valve rod 302, and drives the toothed ring 505 to rotate by a first preset angle through the second bevel gear 503, the second connecting rod 502 and the third flat gear 504.
When the traditional flame gun is indirectly used, the flame gun is easy to always flame, namely, liquefied gas is continuously conveyed to the nozzle 5, so that empty burning occurs, loss of the liquefied gas is caused, certain threat is caused to surrounding personnel, and if the fire is liable to be caused by carelessness. In this embodiment, the valve rod 302 may drive the positioning plate 304 to rotate by a third preset angle, so as to block the gas flowing from the first gas outlet pipe 4. The first flat gear 401 rotates along with the valve rod 302, and drives the ball valve 405 to rotate by a second preset angle through the second flat gear 404 and the first connecting rod 403, so that gas circulates from the gas inlet pipe 402, meanwhile, the first bevel gear 501 rotates along with the valve rod 302, and drives the toothed ring 505 to rotate by a first preset angle through the second bevel gear 503, the second connecting rod 502 and the third flat gear 504, so that the second gas outlet pipe 506 is staggered with the gas outlet hole 507, and the gas is blocked from entering the second gas outlet pipe 506 from the gas storage space, thereby realizing temporary gas storage of the gas storage space. The embodiment can solve the problem of empty burning, does not need to switch the gas tank valve 6 and the gas control valve 7 for multiple times, and is simpler to operate.
As an example, the second preset angle and the third preset angle may be 90 °, and the first preset angle may be sufficient to enable the second air outlet pipe 506 to be staggered from the air outlet hole 507. For example, when the flame gun is indirectly used, the hand wheel 301 can be rotated, and since the positioning plate 304 on the hand wheel 301 is locked by the limiting frame 305, the positioning plate 304 can only rotate 90 ° anticlockwise based on the top-down view, and the positioning plate 304 drives the sealer 303 to rotate 90 ° anticlockwise through the valve rod 302, so that the sealer 303 cuts off the first air outlet pipe 4, and the liquefied gas cannot continuously flow to the nozzle 5 through the first air outlet pipe 4, and along with the cut off of the flowing of the liquefied gas, the flame at the nozzle 5 gradually decreases until the residual liquefied gas at one side of the first air outlet pipe 4 near the nozzle 5 is burned out. If the interval time of intermittent operation is short, the liquefied gas remained in the first air outlet pipe 4 can realize the flame spraying of the nozzle 5 in a short time, namely in a working state, secondary ignition is not needed, and if the interval time is long, secondary ignition is carried out when working again. When the valve rod 302 rotates 90 degrees anticlockwise, the valve rod 302 synchronously drives the first flat gear 401 and the first bevel gear 501 to rotate 90 degrees anticlockwise, the first flat gear 401 drives the second flat gear 404 to rotate 90 degrees clockwise, the second flat gear 404 drives the ball valve 405 to rotate 90 degrees clockwise through the first connecting rod 403, the air inlet pipe 402 is in a communicating state, air can enter an air storage space of the air storage pipe 406 through the air inlet pipe 402, the air storage effect is further achieved, the air pressure in the hose 2 is prevented from being overlarge, and meanwhile stored liquefied gas can be reused when the flame gun is continuously used, and waste is avoided.
When the first bevel gear 501 rotates 90 ° anticlockwise, based on the right-to-left view, the first bevel gear 501 synchronously drives the second bevel gear 503 to rotate 90 ° anticlockwise, the second bevel gear 503 drives the third flat gear 504 to rotate 90 ° anticlockwise through the second connecting rod 502, the third flat gear 504 drives the toothed ring 505 to rotate clockwise by a certain angle, so that the gas outlet 507 rotates to a position staggered with the second gas outlet pipe 506, further, during intermittent operation, the liquefied gas stored in the gas storage space cannot flow to the nozzle 5 through the second gas outlet pipe 506, and when the flame gun is used again, the worker rotates the sealer 303 back to the original position, so that the gas outlet 507 is aligned with the second gas outlet pipe 506 again, and then the liquefied gas in the gas storage space can flow to the nozzle 5, thereby realizing the utilization of the liquefied gas and reducing waste.
When the flame gun is stopped, the air supply can be stopped firstly, then the hand wheel 301 is rotated again, the inner part of the first air outlet pipe 4 is blocked by the sealer 303 again, backfire is prevented from occurring until flame is extinguished, meanwhile, the liquefied gas remained in the hose 2 enters the air storage space from the air inlet pipe 402, the air control valve 7 is closed, finally, the sealer 303 is rotated back to the initial state by rotating the hand wheel 301, a small amount of residual liquefied gas in the air storage space is discharged, and the liquefied gas can be effectively prevented from being remained in the hose 2 and the inner part of the first air outlet pipe 4, so that safety threat is avoided.
