Description

Technical Field

[0001] This utility model relates to the field of lighter technology and is a head structure for a grinding wheel lighter. Background Technology

[0002] As an important branch of modern ignition tools, the background of the flint lighter encompasses multiple dimensions, including historical evolution, technological principles, and cultural value. Its main structure includes a flint wheel, a firestone, and fuel, primarily compressed gases such as butane and propane, which are flammable and odorless. Based on industry design experience and a search of existing solutions, most flint lighter patents describe the overall structural components, with fewer detailing the construction of the lighter head itself. Currently, most lighters on the market use a combination of inner and outer heads. This structure, when applied to flint lighters, is prone to problems such as component misalignment. The reason for this is that the inner and outer heads are detachable, while flint lighters rely mainly on the friction between the flint wheel and the flint, resulting in significant vibration. A search revealed patent application CN200910162026.5, entitled "Method for Manufacturing a Battery Lighter," which proposes a one-piece injection-molded independent body, summarizing the construction of the casing, inner head, and outer head. This led to the discovery that, in fully integrated production, the materials used for the casing storing gases such as butane, as well as the assembly units formed by internal and external mechanisms, are often the same. However, in reality, the actual usage requirements of the two are different, and the materials should also be different. These designs essentially increase the cost of using two different materials. Utility Model Content

[0003] Purpose of the utility model: Based on the problems mentioned in the background art, a head structure for a grinding wheel lighter is proposed.

[0004] Technical solution: A head structure for a grinding wheel lighter, comprising: The main body is symmetrically designed and includes a first annular portion, an assembly portion connected to the top of the first annular portion, and a second annular portion connected to the bottom of the first annular portion. The bottom of the second annular portion has three holes, which respectively form a valve portion, a bearing portion, and a safety portion. The valve section is a tubular structure, with its bottom extending out from the bottom of the second annular section and its top extending into the interior of the second annular section. The supporting part is a tubular structure closed at one end; One end of the safety part extends out of the bottom of the second annular part, and the safety part has a safety hole that is connected to the lighter fuel tank. The first annular part, the second annular part, the valve part, the bearing part, and the safety part are integrally formed.

[0005] Furthermore, the assembly part has a first mounting hole, a second mounting hole, and a slot located inside the assembly part, respectively, from top to bottom.

[0006] Furthermore, the area formed by the circumference of the second annular portion is smaller than the area formed by the circumference of the first annular portion.

[0007] Furthermore, the safety hole is a T-shaped hole.

[0008] A fuselage assembly includes any one of the above-mentioned head structures for a grinding wheel lighter, and also includes a fuselage, wherein the open end face of the fuselage is adapted to a first annular portion, and the inner surface of the open end is adapted to the outer peripheral surface of a second annular portion.

[0009] Furthermore, the interior of the fuselage is divided into three vertical regions, corresponding to the valve section, the load-bearing section, and the safety section, respectively; the tops of the three vertical regions are interconnected.

[0010] Furthermore, the cross-sections of the bottom end faces of the valve section, the bearing section, and the safety section are all smaller than the cross-sections of their corresponding three vertical regions.

[0011] Furthermore, the length of the supporting part is between 1 / 4 and 1 / 3 of the fuselage length.

[0012] Furthermore, the outer surface of the fuselage has a multi-level stepped design.

[0013] Furthermore, the outer surface of the fuselage is provided with multiple sets of symmetrical oblique grooves or multiple sets of symmetrical protrusions.

[0014] Beneficial effects

[0015] 1. Unlike existing solutions, this application integrates the first annular part, the second annular part, the valve part, the load-bearing part, the safety part, and the assembly part into one piece, reducing assembly complexity. Furthermore, it assembles the parts with the fuselage. In actual use, the materials of the head structure and the fuselage can be selected according to the specified requirements.

[0016] 2. Compared to existing designs, the safety hole in the safety section of this application is equipped with a sealed steel ball. When the gas inside the machine body encounters high temperature and the internal pressure rises to a predetermined pressure, the steel ball pops out to automatically release pressure, thus preventing the sudden explosion of butane at high temperature.

[0017] 3. Furthermore, the optimization of this application lies in that by dividing the fuselage into sections, the double-ribbed sections make the gas container more pressure resistant and reduce the risk of gas explosion. At the same time, the safety hole is used in conjunction with one of the sections, so that under high pressure, the gas inside can break through the sealed steel ball in the safety hole to achieve the purpose of pressure relief, further reducing the risk of explosion.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] This application relates to the installation scheme of specific components such as air valves and flints, as well as the contents of each component. Existing grinding wheel parts can be referenced, and there are also many patent contents that can be referenced, such as patent application numbers CN200910162026.5, CN201811509634.4, and CN202022866478.6. Therefore, the existing technical contents will not be described in this application.

[0024] Example 1

[0025] Based on the problems mentioned in the background art, the core content of this embodiment lies in the description of the various functional parts inside the machine head structure. Unlike the machine body proposed in application number CN200910162026.5, which is a single injection-molded independent body and summarizes the structure of the casing, inner machine head, and outer machine head, this application proposes that the inner and outer machine heads are integrally molded and designed separately, which differs from the above. The specific structure is as follows, such as... Figure 1 and Figure 3As shown, the device includes a main body comprising a first annular portion 1, an assembly portion 2 connected to the first annular portion 1, and a second annular portion 3 connected to the bottom of the first annular portion 1. The bottom of the second annular portion has three holes, forming a valve portion 4, a support portion 5, and a safety portion 6, respectively. The valve portion 4 is a tubular structure, with its bottom extending beyond the bottom of the second annular portion 3 and its top extending into the interior of the second annular portion 3. One end of the safety portion 6 extends beyond the bottom of the second annular portion 3, and the safety portion 6 has a safety hole 10 connected to the lighter body 11. In this embodiment, the first annular portion 1, the second annular portion 3, the valve portion 4, the support portion 5, and the safety portion 6 are integrally formed, and the main body has a symmetrical design. Through the above design, this application integrates the first annular portion 1, the second annular portion 3, the valve portion 4, the support portion 5, the safety portion 6, and the assembly portion 2, reducing assembly complexity. Furthermore, when assembled with the lighter body 11, the materials of the head structure and the lighter body 11 can be selected according to specified requirements during actual use. The support portion 5 is used for the flexible mounting of the flint.

[0026] Furthermore, safety hole 10 is a T-shaped hole. Therefore, safety hole 10 in safety section 6 is used to assemble explosion-proof steel balls to prevent the liquid inside the fuselage 11 from exploding at high temperatures. For example, if the pressure of butane rises rapidly at high temperatures, it can be depressurized through safety hole 10 without directly exploding. That is, when the gas inside the fuselage encounters high temperature and its internal pressure rises to a predetermined pressure, the steel ball pops out to automatically depressurize.

[0027] Meanwhile, the T-hole design makes installation easier compared to traditional straight holes, such as... Figure 1 As shown, the safety hole 10 is a T-shaped hole with a round hole at the bottom and a horizontal groove area at the top. A limiting structure can be further installed in the horizontal groove area to prevent the sealed steel ball from moving during transportation or other vibration conditions.

[0028] Furthermore, the assembly part 2 has a first mounting hole 7, a second mounting hole 8, and a slot 9 located inside the assembly part 2, respectively, from top to bottom. The slot 9 is used to install a bracket, the first mounting hole 7 is used to install a grinding wheel, and the second mounting hole 8 is used to install a windproof cover.

[0029] Furthermore, such as Figure 1 As shown, the area formed by the circumference of the second annular portion is smaller than the area formed by the circumference of the first annular portion.

[0030] Example 2

[0031] In conjunction with the solution mentioned in Embodiment 1, this application also proposes a fuselage 11, which is used in conjunction with the solution of Embodiment 1 above, such as... Figure 3As shown, in the scheme where the area formed by the circumference of the second annular portion corresponding to the head structure is smaller than the area formed by the circumference of the first annular portion 1, in this embodiment, the opening end face of the fuselage 11 is adapted to the first annular portion 1, and the inner surface of its opening end is adapted to the outer peripheral surface of the second annular portion.

[0032] At the same time, such as Figure 2 As shown, the interior of the fuselage 11 is divided into three vertical regions 12, which correspond to the valve section 4, the support section 5, and the safety section 6, respectively. The tops of the three vertical regions 12 are interconnected and are inflated through explosion-proof pressure relief holes.

[0033] Correspondingly, such as Figure 2 and Figure 3 As shown, the cross-sections of the bottom end faces of the valve section 4, the bearing section 5, and the safety section 6 are all smaller than the cross-sections of their corresponding three vertical regions 12.

[0034] Meanwhile, the length of the bearing section 5 is 1 / 4 to 1 / 3 of the length of the fuselage 11, which is used to store more flints and extend the service life of the machine.

[0035] Through the above design, the butane liquid is separated by three vertical regions 12, enhancing the strength of the body 11 and reducing the amount of butane. Simultaneously, the longer length of the support section 5 means that the middle vertical region 12 holds less butane liquid. In actual use, the butane content in the vertical region 12 connected to the valve section 4 decreases first, and then the body 11 is manually inverted, allowing the butane to flow from the middle, third vertical region 12 into this region. Furthermore, the third vertical region 12 is connected to the safety section 6, allowing for pressure relief in dangerous situations, thus ensuring the lighter's safety.

[0036] By dividing the fuselage into sections with double ribs, the gas tank becomes more pressure-resistant, reducing the risk of liquid explosion. At the same time, a safety vent is used in one of the sections, allowing the gas inside to break through the sealed steel ball in the safety vent under high pressure, thus achieving pressure relief and further reducing the risk of explosion. This also significantly reduces the risk of the fuselage exploding.

[0037] Furthermore, the outer surface of the fuselage 11 has a multi-level stepped design, and the outer surface of the fuselage 11 is provided with multiple sets of symmetrical oblique grooves or multiple sets of symmetrical protrusions.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
