Description

Technical Field

[0001] This utility model relates to the field of flame injector technology, specifically to a segmented folding flame injector. Background Technology

[0002] Flame throwers are among the most common pieces of equipment in industrial applications. Pneumatic flame throwers use the combustion of combustible gas, typically a mixture of hydrogen or acetylene and air, to provide a heat source for human use. Flame throwers can also be used for everyday recreational purposes, such as grilling steaks or burning grass. The main structure of a flame thrower includes a nozzle and a body. A four-way valve is installed on the body, connecting to a gas cylinder. The gas cylinder supplies gas to the body and nozzle through the four-way valve. A piezoelectric generator is installed on the nozzle, acting as an ignition device to ignite the gas and produce a flame at the tip of the nozzle.

[0003] To improve the flamethrower's appearance, the casing was designed in the shape of a rifle, with the nozzle and body housed inside. A trigger connected to a four-way valve was mounted on the body, allowing the flame size to be controlled by pressing the trigger. However, the relatively long casing makes the flamethrower less portable and inconvenient to store, and adjusting the flame size by pressing the trigger is quite strenuous. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a segmented folding flamethrower to solve the technical problems of poor portability and inconvenience in storage of existing flamethrowers.

[0005] To solve the above-mentioned technical problems, this utility model provides a segmented folding flame injector, comprising:

[0006] The gun head and the gun body are connected detachably, with the rear end of the gun head and the front end of the gun body having a detachable connector.

[0007] The gun consists of a first housing, a second housing, and a stock. The gun head is connected to the first housing and its front and rear ends protrude from the front and rear sides of the first housing, respectively. The gun body is connected to the second housing and its insertion port is exposed. The first housing is detachably connected to the front end of the second housing, and the stock is connected to the rear end of the second housing.

[0008] A first fixing component is used to fix or separate the first housing and the second housing.

[0009] With the above structure, the segmented folding flamethrower of this utility model has the following advantages: the nozzle and the body are respectively connected to the first housing and the second housing. When the first housing is connected to the second housing, the rear end of the nozzle is inserted into the socket, and the connection between the nozzle and the body is completed at the same time. The first housing and the second housing are fixed by the first fixing component. The first housing and the second housing are released by the first fixing component, so that the first housing and the second housing are separated. When the first housing and the second housing are separated, the nozzle and the body are separated simultaneously, making the flamethrower easy to carry and store.

[0010] As an improvement, the rear end of the first housing is provided with a protrusion, and the front end of the second housing is provided with a slot for the protrusion to be inserted; this structure makes the connection between the first housing and the second housing more stable.

[0011] As an improvement, the first fixing component includes a first movable member, a first spring, a first buckle, and a first slot. The outer wall of the second housing is provided with a first mounting hole. The first movable member is movably connected to the first mounting hole in the left-right direction. The first buckle is provided on the first movable member and located in the slot. The first slot is provided on the outer wall of the protrusion. The first spring is provided between the first movable member and the inner wall of the second housing, so that a part of the first movable member is exposed outside the first mounting hole and the first buckle is engaged in the first slot. With this structure, by pressing the first movable member, the first buckle is driven to leave the first slot, so that the first housing and the second housing can be separated. When the first housing and the second housing are connected, the first spring drives the first movable member to be exposed outside the first mounting hole and drives the first buckle to be engaged in the first slot, thus completing the fixing of the first housing and the second housing.

[0012] As an improvement, the stock is rotatably connected to the rear end of the second housing, and the stock and the second housing are provided with a second fixing component for fixing or rotating the second housing and the stock; with this structure, the rotatable stock can further make the flamethrower easier to carry and store.

[0013] As an improvement, the second fixing component includes a second movable member, a second spring, a second latch, and a second slot. A second mounting hole is provided on the outer wall of the stock. The second movable member is movably connected to the second mounting hole in the left-right direction. The second latch is provided on the second movable member. An extension is provided at the rear end of the second housing. The second slot is provided on the extension. The second spring is provided between the second movable member and the inner wall of the stock, so that a part of the second movable member is exposed outside the second mounting hole and the second latch is engaged in the second slot. With this structure, by pressing the second movable member, the second latch is driven to move away from the second slot, so that the stock can rotate relative to the second housing. When the stock is unfolded, the second spring drives the second movable member to be exposed outside the second mounting hole and drives the second latch to engage in the second slot, thus completing the fixing of the second housing and the stock.

[0014] As an improvement, this utility model also includes a trigger assembly. The gun body is equipped with a multi-way valve, which is connected to an adjustment connector. The trigger assembly includes a first trigger and a second trigger. The first trigger is rotatably connected to the multi-way valve via a first rotating shaft. The first trigger is arranged in the front-to-back direction and its rotation axis is arranged in the left-to-right direction. One end of the first trigger is connected to the adjustment connector. The distance between the other end of the first trigger and the first rotating shaft is greater than the distance between the first trigger's first end and the first rotating shaft. The second trigger is rotatably connected to the second housing via a second rotating shaft. One end of the second trigger abuts against the other end of the first trigger. The other end of the second trigger protrudes outside the second housing. The distance between the other end of the second trigger and the second rotating shaft is greater than the distance between the second trigger's first end and the second rotating shaft. By rotating the second trigger, the first trigger is rotated, causing the adjustment connector to adjust the flame size. With this structure, the two lever structures of the first and second triggers make adjusting the flame size more effortless.

[0015] As an improvement, the gun body is equipped with a multi-way valve, which is connected to a pressure regulating valve. The pressure regulating valve is connected to a connector for connecting to a gas cylinder via a pipeline, and the connector is connected to the second housing. With this structure, the stability of the airflow is improved by setting up a pressure regulating valve, thereby improving the stability of the flame.

[0016] As an improvement, a piezoelectric generator is connected to the gun head. The piezoelectric generator is located inside the first housing, with its pressing part protruding outside the first housing. A fixing knob is threaded onto the piezoelectric generator. An abutment part is provided on the inner wall of the first housing. By rotating the fixing knob, the fixing knob abuts against the abutment part. A limiting groove is provided on the piezoelectric generator, and a limiting protrusion is provided on the inner wall of the first housing. The limiting protrusion is engaged in the limiting groove. This structure improves the stability of the connection between the piezoelectric generator and the first housing.

[0017] As an improvement, the rear end of the gun head is provided with an insertion end, which can be detachably inserted into the socket. The gun body is provided with a self-locking component. When the insertion end is inserted into the socket, the rear end of the insertion end is inserted into the self-locking component, which allows airflow to pass through the gun body. With this structure, airflow can only pass through the gun body through the self-locking component when the insertion end is inserted into the socket, preventing air leakage caused by accidental contact with the first fixing component during use, which could lead to separation of the first and second housings, and separation of the gun head and gun body.

[0018] As an improvement, both the gun head and the gun body are equipped with fixing components. The inner walls of the first and second housings are equipped with locking plates for fixing the fixing components. Fixing bolts pass through the first and second housings respectively and are threadedly connected to the fixing components. This structure improves the stability of the connection between the gun head and the gun body and the first and second housings. Attached Figure Description

[0035] The following is a detailed description of a segmented folding flame injector according to the present invention, with reference to the accompanying drawings.

[0036] like Figures 1 to 15 As shown, a segmented folding flamethrower includes a nozzle 1, a body 2, a first housing 4, a second housing 5, and a stock 6. The rear end of the nozzle 1 is detachably connected to the insertion port 3 at the front end of the body 2. The nozzle 1 is connected inside the first housing 4, with its front and rear ends protruding from the front and rear sides of the first housing 4, respectively. (The last sentence appears to be incomplete and possibly refers to a different part of the flamethrower.) Figure 4 and Figure 8 As shown, the rear end of the gun head 1 is provided with an insertion end 26, which can be detachably inserted into the socket 3. The gun body 2 is provided with a self-locking component 27, such as... Figure 13 As shown, when the insertion end 26 is inserted into the socket 3, the rear end of the insertion end 26 is inserted into the self-locking component 27, thus allowing airflow within the gun body 2. The first housing 4, the second housing 5, and the stock 6 are all assembled from left and right halves.

[0037] like Figure 1 As shown, a universal mounting rail 38 is also provided on the upper end of the first housing 4 and the second housing 5. The mounting rail 38 extends from the upper end of the first housing 4 to the upper end of the second housing 5 and can be used to mount scopes, red dot sights, etc. to increase the fun.

[0038] The gas-blocking principle of the self-locking component 27 is existing technology. For example, the tower-shaped spring in the self-locking component 27 works with the sealing ring to seal the gas outlet. When the insertion end 26 is inserted into the self-locking component 27 through the insertion port 3, the insertion end 26 pushes open the sealing ring, allowing the gas to flow out through the self-locking component 27 into the nozzle 1.

[0039] like Figure 7 As shown, the gun body 2 is connected inside the second housing 5 and the socket 3 is exposed. That is to say, the socket 3 is located at the front end of the second housing 5. The first housing 4 is detachably connected to the front end of the second housing 5, and the stock 6 is connected to the rear end of the second housing 5. It should be noted that in this embodiment, the front end is taken as the direction of the flame jet, and the front, back, left and right directions are defined based on this.

[0040] like Figure 4 As shown, the rear end of the first housing 4 has a protrusion 8, such as... Figure 7 As shown, the front end of the second housing 5 is provided with a slot 9 for the protrusion 8 to be inserted. Furthermore, to make the connection between the first housing 4 and the second housing 5 more stable, a limiting guide groove 34 is provided along the contour of the rear end of the first housing 4. Correspondingly, a limiting part 35 is provided along the contour of the front end of the second housing 5. The limiting part 35 matches the limiting guide groove 34. When the first housing 4 and the second housing 5 are connected, the protrusion 8 is inserted into the slot 9, and the limiting part 35 is engaged in the limiting guide groove 34. The insertion port 3 is located above the slot 9, and correspondingly, the insertion end 26 is also located above the protrusion 8. A slide rail 36 is also provided at the upper part of the rear end of the first housing 4 to make the engagement of the first housing 4 and the second housing 5 more stable.

[0041] The nozzle 1 and the body 2 are respectively connected to the first housing 4 and the second housing 5. When the first housing 4 is connected to the second housing 5, the rear end of the nozzle 1 is inserted into the socket 3, thus completing the connection between the nozzle 1 and the body 2. The first housing 4 and the second housing 5 are fixed by the first fixing component 7. The first housing 4 and the second housing 5 are released by the first fixing component 7, so that the first housing 4 and the second housing 5 are separated. When the first housing 4 and the second housing 5 are separated, the nozzle 1 is simultaneously driven to separate from the body 2, making the flamethrower easy to carry and store.

[0042] The first fixing component 7 is used to fix or separate the first housing 4 and the second housing 5; such as Figure 4 , Figure 8 and Figure 9 As shown, the first fixing component 7 includes a first movable member 71, a first spring 72, a first buckle 73, and a first slot 74. The outer wall of the second housing 5 is provided with a first mounting hole 10. The first movable member 71 is movably connected to the first mounting hole 10 in the left-right direction. The first buckle 73 is provided on the first movable member 71 and located in the slot 9. The first slot 74 is provided on the outer wall of the protrusion 8. The first spring 72 is provided between the first movable member 71 and the inner wall of the second housing 5, so that a part of the first movable member 71 is exposed outside the first mounting hole 10 and the first buckle 73 is engaged in the first slot 74.

[0043] In this embodiment, the end face where the first mounting hole 10 is located is opposite to the end face where the first slot 74 is located. That is, taking this embodiment as an example, the first mounting hole 10 is located on the left end face of the first housing 4, the first spring 72 is located between the first movable member 71 and the right inner wall of the second housing 5, and the first slot 74 is located on the right end face of the protrusion 8. Pressing the first movable member 71 causes the first movable member 71 to move to the right. At this time, the first buckle 73 moves to the right away from the first slot 74 and separates the first housing 4 from the second housing 5. After releasing the first movable member 71, the compressed first spring 72 causes the first movable member 71 and the first buckle 73 to return to their original positions. When connecting the first housing 4 and the second housing 5, the first housing 4 is inserted into the second housing 5. The first buckle 73 is provided with a guide arc surface. During the insertion process, the protrusion 8 contacts the guide arc surface, causing the first buckle 73 to move to the right. As the protrusion 8 is inserted, the first buckle 73 is engaged in the first slot 74 under the action of the first spring 72.

[0044] Furthermore, the airflow inside the gun body 2 can only be facilitated by the self-locking component 27 when the insertion end 26 is inserted into the socket 3, preventing air leakage caused by accidental contact with the first fixing component 7 during use, which would result in the separation of the first housing 4 and the second housing 5, and the separation of the gun head 1 and the gun body 2.

[0045] like Figure 10 As shown, the stock 6 is rotatably connected to the rear end of the second housing 5, and the stock 6 and the second housing 5 are provided with a second fixing component 11 for fixing or rotating the second housing 5 and the stock 6.

[0046] like Figure 10 and Figure 11 As shown, the second fixing component 11 includes a second movable member 111, a second spring 112, a second buckle 113, and a second slot 114. A second mounting hole 12 is provided on the outer wall of the stock 6. The second movable member 111 is movably connected to the second mounting hole 12 in the left-right direction. The second buckle 113 is provided on the second movable member 111. An extension 13 is provided at the rear end of the second housing 5. The second slot 114 is provided on the extension 13. The second spring 112 is provided between the second movable member 111 and the inner wall of the stock 6, so that a part of the second movable member 111 is exposed outside the second mounting hole 12 and the second buckle 113 is engaged in the second slot 114.

[0047] Taking this embodiment as an example, the extension 13 is located on the left side of the rear end of the second housing 5, the second mounting hole 12 is located on the left end face of the stock 6, the second spring 112 is located between the second movable member 111 and the inner wall of the right side of the stock 6, the second latch 113 is located on the left end face of the second movable member 111, the extension 13 covers the second latch 113, and pressing the second movable member 111 causes it to move to the right. At this time, the second latch 113 moves to the right away from the second latch 114, and the stock 6 can rotate. The pivot of the stock 6 is located on its right side. Figure 11 As shown, the stock 6 rotates to the right and folds into the right end face of the second housing 5; when the stock 6 is unfolded, it rotates in the opposite direction, and a guide ramp is provided on the second latch 113. The extension 13 abuts against the guide ramp, causing the second latch 113 to move to the right. As the stock 6 rotates, the second latch 113 is engaged in the second latch 114 under the action of the second spring 112, thus completing the fixation of the second housing 5 and the stock 6.

[0048] This utility model also includes a trigger assembly 16, such as Figure 12 As shown, the gun body 2 is equipped with a multi-way valve 14, specifically a four-way valve. The front end of the four-way valve is connected to the gun body 2, and the rear end of the four-way valve is connected to a pressure regulating valve 19. The pressure regulating valve 19 is connected to a connector 20 for connecting to a gas cylinder via a pipeline. The connector 20 is connected to the second housing 5. Specifically, the connector 20 is located at the bottom of the second housing 5, so the gas cylinder (gas source) is also connected to the bottom of the second housing 5. An adjustment knob 30 is connected to the upper end of the four-way valve. By rotating the adjustment knob 30, the gas output is changed, thereby adjusting the size of the small flame. An adjustment connector 15 is connected to the lower end of the four-way valve. Moving the adjustment connector 15 downward can increase the gas output, thereby adjusting the size of the large flame.

[0049] like Figure 15 As shown, the pipeline in this embodiment is a brass tube 39. After the brass tube 39 is placed into the pressure plate, it is bent and upset. The two ends are connected to the pressure regulating valve 19 and the connector 20 by screws and sealing rings to connect the airflow.

[0050] like Figure 12 As shown, the trigger assembly 16 includes a first trigger 161 and a second trigger 162. The first trigger 161 is rotatably connected to the multi-way valve 14 via a first rotating shaft 17. The first trigger 161 is arranged in the front-to-back direction and its rotation axis is arranged in the left-to-right direction. One end of the first trigger 161 is connected to an adjusting connector 15. The distance between the other end of the first trigger 161 and the first rotating shaft 17 is greater than the distance between one end of the first trigger 161 and the first rotating shaft 17. The second trigger 162 is located below the first trigger 161. The second trigger 162 is rotatably connected to the second housing 5 via a second rotating shaft 18. One end of the second trigger 162 abuts against the other end of the first trigger 161. The other end of the second trigger 162 protrudes outside the second housing 5. The distance between the other end of the second trigger 162 and the second rotating shaft 18 is greater than the distance between one end of the second trigger 162 and the second rotating shaft 18. By rotating the second trigger 162, the first trigger 161 is rotated, thereby adjusting the flame size via the adjusting connector 15.

[0051] In this embodiment, one end of the second trigger 162 and the other end of the second trigger 162 are bent together. In the initial state, one end of the second trigger 162 is set horizontally and located below the other end of the first trigger 161, and the other end of the second trigger 162 is set vertically. A second through hole 32 is provided on the second housing 5, and the other end of the second trigger 162 is exposed in the second through hole 32.

[0052] When the second trigger 162 is pressed, the other end of the second trigger 162 deflects backward, and one end of the second trigger 162 deflects upward, causing the other end of the first trigger 161 to deflect upward, causing one end of the first trigger 161 to deflect downward, causing the adjusting joint 15 to move downward. After the second trigger 162 is released, the spring at the adjusting joint 15 causes the adjusting joint 15 to return to its original position, and at the same time the first trigger 161 and the second trigger 162 return to their original positions synchronously.

[0053] The connector 20 is located in front of the second trigger 162. When in use, the user has one hand on the second trigger 162 and the other hand holding the bottom of the first housing 4. At this time, the connector 20 (gas cylinder) is between the two hands, which makes it easier to use.

[0054] In addition, a third through hole 33 is provided on the upper part of the second housing 5 for hand-held use.

[0055] like Figure 5 As shown, the gun head 1 is connected to a piezoelectric generator 21. The piezoelectric generator 21 is located inside the first housing 4 and the pressing part of the piezoelectric generator 21 is exposed outside the first housing 4. The first housing 4 is provided with a first through hole 31, and the pressing part of the piezoelectric generator 21 is exposed inside the first through hole 31.

[0056] like Figure 5 and Figure 6 As shown, a fixing knob 22 is threaded onto the piezoelectric element 21, and an abutment portion 23 is provided on the inner wall of the first housing 4. In this embodiment, the abutment portion 23 is located in front of the fixing knob 22. By rotating the fixing knob 22, the fixing knob 22 abuts against the abutment portion 23. A limiting groove 24 is provided on the piezoelectric element 21, and a limiting protrusion 25 is provided on the inner wall of the first housing 4. Figure 6 The limiting protrusion 25 is engaged within the limiting groove 24. Furthermore, snap-fit ​​pieces are respectively provided on the left and right inner walls of the first housing 4, allowing the piezoelectric 21 to be secured between the snap-fit ​​pieces on both sides. Compared to the prior art method of fixing the piezoelectric 21 with a bracket, the fixing method in this embodiment is more stable. In addition, the prior art piezoelectric 21 is equipped with structures such as a copper sleeve, and the copper sleeve is connected to the gun head 1 through a metal bracket for conductivity, resulting in a relatively complex structure. Figure 14 As shown, in this embodiment, the copper sleeve and other structures are omitted, and the conductive rod 37 on the piezoelectric 21 is directly connected to the gun head 1 to achieve conductivity.

[0057] like Figure 5 and Figure 8As shown, both the gun head 1 and the gun body 2 are equipped with fixing parts 28, such as... Figure 14 As shown, in this embodiment, the fixing member 28 is a hexagonal nut, which is fixed to the gun head 1 and the gun body 2 by bolts. The inner wall of the first housing 4 and the inner wall of the second housing 5 are provided with a locking platform 29 for fixing the fixing member 28. The locking platform 29 is set on the left and right inner walls of the first housing 4 and the left and right inner walls of the second housing 5. The fixing bolts pass through the first housing 4 and the second housing 5 respectively and are threadedly connected to the fixing member 28.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
