Description

Technical Field

[0001] This utility model belongs to the field of lighter technology, and in particular relates to a heat-insulating cup and a gasifier and lighter that are used with the heat-insulating cup. Background Technology

[0002] The heat-insulating cup is an accessory of a lighter. Together with the gas outlet, air mixing tube, and conductive cup, it forms a vaporization furnace. A combustion chamber is formed inside the heat-insulating cup, and the mixed gas flows into the heat-insulating cup and is ignited to form a flame. Existing heat-insulating cups are cylindrical, with a conductive cup fitted on the outside and top of the heat-insulating cup, and the gas outlet is located inside the heat-insulating cup. To ensure the ignition rate, as disclosed in a lighter gas outlet structure with application number CN202420944701X, a conductive head is set on the gas outlet. The conductive component on the conductive cup cooperates with the conductive head to form an electric spark, which ignites the mixed gas inside the heat-insulating cup.

[0003] In conventional designs, conductive components often employ conductive rings, which are pressed against the upper surface of the insulated cup and do not extend into the inner area of ​​the cup's rim to avoid interfering with the normal diffusion of the gas mixture. However, during actual ignition, the rim of the insulated cup may obstruct the connection between the conductive ring and the conductive head. Since the formation of an electric spark depends on the electric field strength between the two points reaching the air breakdown threshold, the rim not only alters the electric field distribution but may also interrupt the electric field due to the insulating material, thus inhibiting the normal generation of an electric spark and hindering reliable ignition. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Example 1: As Figure 1 As shown, an insulated cup includes a cup body 11, an installation port 12 is provided on the inner bottom surface of the cup body 11, and at least one groove 13 is provided on the upper end of the cup body 11, the groove 13 penetrating the inner and outer side walls of the cup body 11.

[0021] When there are multiple grooves 13, the multiple grooves 13 are distributed at equal intervals along the circumferential direction.

[0022] Example 2: Figure 2As shown, the rest of the parts are the same as in Embodiment 1, except that the sidewalls of the groove 13 are inclined from bottom to top and away from the other sidewall to increase the opening size of the groove 13, making the discharge channel wider and easier to form an electric spark. In addition, the cup body 11 is usually made of ceramic. By setting the sidewalls inclined, the sidewalls are less likely to collapse during firing, which helps to ensure the yield rate.

[0023] Example 3: Figure 3 and Figure 4 As shown, the rest of the structure is the same as in Embodiment 1, except that the cross-section of the cup body 11 is elliptical, and the groove 13 is located at the long axis end of the cup body 11. In this structure, one or two grooves 13 are provided.

[0024] In this embodiment, the bottom of the groove 13 is inclined downward from the outside to the inside.

[0025] In this embodiment, the groove 13 is divided into an upper section 131 and a lower section 132. The sidewall of the upper section 131 of the groove 13 is inclined from bottom to top and away from the other sidewall. The sidewall of the lower section 132 of the groove 13 extends in the vertical direction.

[0026] See Figure 7 The structure of the second conductive element 41 is provided on the windproof cover 4. The groove 13 in this design can avoid interference between the second conductive element 41 and the heat insulation cup 1. The inclined setting of the upper section 131 helps to quickly align and assemble the middle part of the second conductive element 41 with the groove 13.

[0027] The elliptical cup body 11 is designed for two purposes: first, it facilitates the operator to assemble the cup body 11 at the specified angle, so that the second conductive component 41 is aligned with the groove 13 and can be smoothly inserted into the cup body 11; second, when the short axis end of the cup body 11 abuts against the inner wall of the windproof cover 4, it can prevent the cup body 11 from rotating during the flame adjustment process, thus avoiding collision damage between the cup body 11 and the second conductive component 41.

[0028] Example 4: Figure 5 As shown, a gasification furnace includes a gas outlet 2, a conductive cup 3, and a heat-insulating cup 1 as described in Embodiments 1, 2, or 3. The gas outlet 2 is disposed inside the heat-insulating cup 1, and the conductive cup 3 is sleeved on the outside of the heat-insulating cup 1. A first conductive element 31 extending to the upper end of the heat-insulating cup 1 is disposed on the conductive cup 3. The first conductive element 31 covers a groove 13, and the distance between the first conductive element 31 covering the groove 13 and the gas outlet 2 is within the ignition distance range. Preferably, the conductive cup 3 is an iron cup, and the first conductive element 31 is preferably annular and integrally formed with the iron cup.

[0029] Example 5: Figure 6As shown, the rest of the parts are the same as in Embodiment 4, except that the gas outlet 2 includes a gas outlet head 21 and a conductive head 22 fixedly mounted on the gas outlet head 21. The distance between the first conductive member 31 covering the groove 13 and the conductive head 22 is within the ignition distance range. Preferably, the conductive head 22 and the gas outlet head 21 are integrally formed, which facilitates one-time processing.

[0030] It should be noted that the air outlet 21 can adopt a pagoda structure or a direct-flow structure, which are conventional structures in this field.

[0031] Example 6: Figure 3 , Figure 7 and Figure 8 As shown, a lighter includes a windproof cover 4, a gas outlet 2, an air mixing tube 5, a piezoelectric ceramic 6, a rocker arm 7, and a heat-insulating cup 1 as described in Embodiments 1, 2, or 3. The windproof cover 4 covers the heat-insulating cup 1, the gas outlet 2 is disposed inside the heat-insulating cup 1, and at least one second conductive element 41 is provided on the windproof cover 4. The second conductive element 41 extends into the heat-insulating cup 1, with its middle portion located at a groove 13. The distance between the second conductive element 41 and the gas outlet 2 is within the ignition distance range. The upper end of the air mixing tube 5 is connected to the gas outlet 2. The rocker arm 7 abuts against the air mixing tube 5 and the piezoelectric ceramic 6, respectively. The wire 61 on the piezoelectric ceramic 6 is directly or indirectly connected to the second conductive element 41. A direct connection means that the wire 61 is directly connected to the second conductive element 41, while an indirect connection means that the wire 61 is connected to the second conductive element 41 through the windproof cover 4. Furthermore, when an elliptical cup body 11 is used, the short axis end of the cup body 11 abuts against the inner wall of the windproof cover 4.

[0032] In this embodiment, the second conductive element 41 is in the form of a sheet or a needle. When it is in the form of a sheet, the side of the second conductive element 41 that extends into the heat insulation cup 1 is preferably pointed.

[0033] When the piezoelectric ceramic 6 is discharged by pressing the button 8 directly or indirectly, the piezoelectric ceramic 6, the windproof cover 4, the second conductive element 41, the gas outlet 2, the air mixing pipe 5, and the rocker 7 form a discharge circuit. At the same time, the rocker 7 rotates and lifts the gasification furnace composed of the air mixing pipe 5, the heat insulation cup 1, and the gas outlet 2 to open the gas valve of the gas storage tank 9. The gas in the gas storage tank 9 is mixed with air through the air mixing pipe 5 to form a mixed gas. The mixed gas flows into the heat insulation cup 1, and an electric spark is formed between the second conductive element 41 and the gas outlet 2 to ignite the mixed gas and form a flame.

[0034] It should be noted that when the rocker arm 7 rotates and lifts the gasifier consisting of the air mixing pipe 5, the insulation cup 1, and the gas outlet 2, the distance between the second conductive component 41 and the gas outlet 2 is within the ignition distance range. When the rocker arm 7 is in its initial state without pressing the button 8, the gasifier is not lifted, and the distance between the second conductive component 41 and the gas outlet 2 may not be within the ignition distance range. Accordingly, in the design, a gap of at least the lifting displacement is reserved between the bottom of the groove 13 and the second conductive component 41 to ensure that the insulation cup 1 and the second conductive component 41 will not collide when the gasifier is lifted.

[0035] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
