Description

Technical Field

[0001] This utility model relates to an ignition device, specifically a flamethrower. Background Technology

[0002] Currently, flamethrowers are commonly used for outdoor barbecues, jewelry welding, and car repair. Existing flamethrowers generally consist of a flamethrower body, which mainly includes a piezoelectric device, an ignition switch, a gas chamber, and a gas valve assembly. In use, simply turning on the ignition switch compresses the piezoelectric cap within the device. When the compression stroke reaches the ignition stroke, the piezoelectric device releases high-voltage electrical energy by striking the piezoelectric crystal with its internal hammer. This energy is then transmitted to the generator connected to the lead wire, producing an electric spark at the gas outlet in the nozzle. Simultaneously, the ignition switch presses one end of a rocker arm, which pushes up the gas outlet needle, releasing gas from the outlet valve. The released gas ignites upon contact with the electric spark. However, adjusting the flame size usually requires adjusting the gas flow rate. Therefore, operating existing flamethrowers typically involves holding and pushing the piezoelectric switch with one hand while simultaneously rotating it with the other to adjust the flame size, making operation inconvenient.

Detailed Implementation

[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0031] Depend on Figure 1 Combination Figure 2-9As shown, a flamethrower includes a housing 1, and further includes:

[0032] Air box 2 is located inside housing 1;

[0033] Gasifier 3 is mounted on shell 1;

[0034] Gas outlet assembly 4 is mounted on gas box 2 and connected to gasifier 3; gas outlet assembly 4 includes mounting component 41, gas outlet pipe 42, gas outlet needle 43 and spring plate 44; spring plate 44 is connected to gas outlet needle 43 and is used to drive gas outlet needle 43 to move and release gas; gas outlet pipe 42 is inserted into mounting component 41.

[0035] Ignition device 5, the ignition device 5 includes ignition switch 51 and first circuit board 52, the ignition switch 51 is connected to the first circuit board 52 and controls ignition through the first circuit board 52;

[0036] The adjusting component 6, by rotating, causes the gas outlet pipe 42 to move relative to the mounting component 41, adjusting the gas output and thus switching the ignition switch 51 for ignition. The beneficial effect of this invention is that by providing an adjusting component, the ignition switch can be switched and the gas output adjusted simultaneously when the adjusting component rotates. This allows for automatic ignition and flame size control by rotating the adjusting component with one hand, freeing up both hands and facilitating operation. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. Specifically, this invention has a built-in ignition switch; rotating the adjusting component controls the ignition switch for ignition, and simultaneously controlling the flame size.

[0037] The air box 2 is equipped with a lifting track 21, and the adjusting member 6 is equipped with an adjusting block 61. The adjusting block 61 is located on the lifting track 21. When the adjusting member 6 rotates, the adjusting block 61 moves along the lifting track 21, thereby causing the adjusting member 6 to move vertically relative to the air box 2, which in turn causes the springboard 44 to move vertically. The lifting track allows the adjusting member to move vertically when rotating, thereby causing the springboard to move vertically and opening the air outlet needle to rise synchronously and release air. Specifically, the air outlet assembly is actually implemented using an existing structure, which will not be described in detail here.

[0038] The air outlet needle 43 is inserted into the air outlet pipe 42. The spring plate 44 is mounted on the adjusting member 6 and is linked to the adjusting member 6. The adjusting member 6 rotates to drive the spring plate 44 to move vertically, causing the air outlet needle 43 to slide relative to the air outlet pipe 42. Specifically, the adjusting member 6 is provided with a receiving groove 62, and the spring plate 44 is located in the receiving groove 62 and moves vertically when the adjusting member 6 rotates. This structure allows the air outlet needle to rise reliably when the adjusting member rotates, at which point the air outlet assembly can be opened to release air.

[0039] The air outlet pipe 42 is inserted into the mounting component 41 and threadedly connected to it. The mounting component 41 is connected to the air box 2. The adjusting component 6 rotates to move the air outlet pipe 42 relative to the mounting component 41, thereby adjusting the air output. Specifically, the adjusting component 6 is provided with locking teeth 63, which are sleeved on the outside of the air outlet pipe 42 and, when the adjusting component 6 rotates, drive the air outlet pipe 42 to rotate relative to the mounting component 41 to adjust the air output. This structure allows the air outlet pipe to rotate relative to the mounting component when the adjusting component rotates, thus adjusting the air output. Adjusting the air output by changing the relative position of the air outlet pipe and the mounting component is existing technology; specifically, all air outlet components are implemented using existing technology.

[0040] The adjusting member 6 is provided with a pressing part 64, which has a first position for pressing the ignition switch 51 and a second position for separating from the ignition switch 51 when the adjusting member 6 rotates, switching the ignition switch 51. The pressing part allows the ignition switch to be pressed; when the adjusting member rotates upwards, the pressing part separates from the ignition switch, opening the gas outlet needle and simultaneously switching the ignition switch to achieve ignition. Continued rotation of the adjusting member adjusts the gas output and flame size. This invention allows for one-handed rotation of the adjusting member and automatic ignition via circuitry. It incorporates an ignition switch, eliminating the need to press the ignition switch; ignition is achieved simply by rotating the adjusting member.

[0041] This utility model also includes a central frame 7 and a limiting member 8. The central frame 7 is connected to the housing 1 and / or the air box 2. The adjusting member 6 is provided with an operating part 65. The operating part 65 is sleeved on the outside of the central frame 7 and / or the housing 1 and rotates relative to the central frame 7 and / or the housing 1. The limiting member 8 has a first position that limits the adjusting member 6 and a second position that unlocks the adjusting member 6 to rotate freely. In this utility model, the adjusting member is limited by the limiting member. Generally, the adjusting member has a notch that matches the limiting member. Specifically, the operating part of the adjusting member is located on the outer side of the outer wall of the housing, and the receiving groove of the adjusting member is located on the inner side of the inner wall of the housing. The operating part and the receiving groove are connected by a connecting plate and have an arc-shaped cavity. Specifically, the operating part of the adjusting member is sleeved on the outside of the housing and / or the central frame and cooperates with the circumferential rotation and vertical sliding of the housing and / or the central frame. That is, when the operating part of the adjusting member rotates, the adjusting block moves along the lifting track, causing the adjusting member to slide vertically relative to the housing and / or the central frame.

[0042] This utility model also includes a high-pressure transformer 53 and an air inlet 54. The air inlet 54 is connected to the gasifier 3. The gasifier 3 has a ceramic seat 31 at its end. The high-pressure transformer 53 is connected to a first circuit board 52, enabling the first circuit board 52 to achieve arc ignition at the ceramic seat 31. The ignition switch 51 is built into the housing 1. This utility model uses arc ignition, resulting in a higher flame temperature and more stable performance. In fact, the gasifier is implemented using existing technology, but a simplified explanation is provided for ease of understanding. Specifically, the gasifier includes a main body and a separate tail section. The ceramic seat is located at the top of the main body's atomization. Gas is accelerated and ejected upwards through small holes in the silver sheet at the tail section. The separation in the middle requires a certain distance, which is within a controllable range. At this time, air can be mixed in, achieving fuel-gas mixing. After the mixed gas reaches the main body's atomization, it is ignited by an arc at the ceramic seat.

[0043] This utility model also includes a lamp holder 91, which houses a second circuit board 92 and a lighting lamp 93. A lighting switch 94 is mounted on the lamp holder 91, connected to the lighting lamp 93 via the second circuit board 92 and used to control the switching of the lighting lamp 93. The lighting lamp 93 is located on the housing 1 at the opposite end from the gasifier 3. A high-powered flashlight is provided at the rear of the housing to enhance the product's practicality.
