Description

Technical Field

[0001] The utility model specifically relates to a novel grinding wheel lighter. Background Art

[0002] Most of the grinding wheel lighters are disposable lighters. Specifically, the flint in the grinding wheel lighter is usually designed as a non-replaceable assembly. When the flint fails, it is not convenient to replace the flint. When the flint is consumed, the entire lighter will be discarded as waste, which is not in line with the trend of environmental protection.

[0003] In view of this, existing grinding wheel lighters have gradually developed replaceable flint types, such as the grinding wheel lighter disclosed in Chinese patent CN219756436U. Although the flint can be replaced, it is necessary to disassemble the entire support frame and then remove the sparking wheel 12 to replace the flint. The replacement method is relatively complicated, and during the disassembly process, the sparking wheel is easily lost, making it impossible to reassemble, and then the lighter needs to be discarded.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] As shown in the figure, the utility model discloses a novel grinding wheel lighter, which comprises a lighter body 1,

[0024] The lighter body includes a fuel tank 11, a middle frame 13 fixedly connected to the fuel tank 11, a fire-discharging assembly 12 arranged on the middle frame, and a sparking wheel 2 and a flint 6 arranged on one side of the fire-discharging assembly. The lighter body is also provided with a flint replacement mechanism, which is arranged on one side of the fire-discharging assembly for placing the flint, and the sparking wheel is arranged above the flint. By rotating the sparking wheel, it can rub against the flint to generate sparks, and then generate flames at the fire-discharging assembly.

[0025] The flint replacement mechanism comprises:

[0026] The flint chamber 8 is integrally formed in the middle frame 13 of the lighter body, and its upper end is open and located at the lower side of the sparking wheel 2. The opening is used to expose the flint 6 and make the flint contact with the sparking wheel. A replacement port 5 is provided on one side of the flint chamber. The replacement port is in the shape of a long strip and is arranged on one side of the middle frame along the moving direction of the flint. It is connected with the flint chamber, and the flint can be put into the flint chamber from there. At the same time, the upper part of the replacement port is a complete structure for supporting and fixing the flint, playing a guiding role for the flint, so that the flint always moves upward and is always in contact with the sparking wheel.

[0027] The push button 4 is provided with an operating part 41 covering the replacement port and a linkage part 42 arranged on the back of the operating part. The linkage part extends from the replacement port into the flint cavity and can move up and down along the replacement port. The linkage part is arranged to drive the flint to move upward. The upper side of the linkage part forms a flint placement cavity. The lower side of the linkage part is provided with an elastic member for driving the flint to move toward the flint wheel. The elastic member is a spring. After the flint is placed in the flint placement cavity, the complete flint will cause the linkage part to compress the spring. When the flint is gradually worn out, the spring is gradually released, thereby causing the linkage part to move upward, thereby driving the flint to move upward, so that the flint can always be in contact with the flint wheel.

[0028] Since the push button needs to move up and down in the replacement port, the linkage part of the push button is placed in the middle position by relying on the restriction of the elastic member 7 and the flint. Preferably, the downward movement path is greater than the upward movement path, so that the upper replacement port can be exposed by sliding down, that is, the push button has a first position in which the elastic member is moved downward to compress the replacement port and expose the replacement port, and a second position in which the replacement port is covered under the action of the elastic member.

[0029] A flint rod 43 for supporting the flint is provided on the upper side of the linkage part. The flint rod can be independently arranged or integrally formed on the linkage part. It is used to drive a large amount of worn flint to continue to move upward, so as to realize the full use of the flint. If the flint rod is not used, a new flint can be added after the linkage part fails to drive the flint to move, and the new flint can drive the old flint to continue to move upward. It can be set according to needs. A positioning column 45 is provided on the lower side for positioning the spring to prevent the spring from falling out.

[0030] The length of the operating part is greater than or equal to the length of the replacement port, and the length of the upper operating part should be slightly greater, that is, after filling with a new flint, its upper side can cover the replacement port, and when the flint needs to be replaced, it only needs to be pulled down to expose the upper replacement port, and the length of the lower side can be longer, which can ensure that when the linkage part moves to the uppermost side, the lower operating part can still cover the replacement port. For this reason, the length of the operating part located on the upper side of the linkage part is smaller than the length of the operating part located on the lower side of the linkage part, that is, when the operating part is in the position when filling with a new flint, its upward movement distance A is smaller than the downward movement distance B, so that its downward movement can expose a larger replacement port, which is more convenient for replacing a new flint. Preferably, the length of the exposed replacement port is adapted to the length of the flint.

[0031] When the push button moves downward, the operating part switches from covering the replacement opening to exposing the replacement opening, and the replacement opening is opened by sliding the push button downward, which is simple and convenient. At the same time, the flint can be replaced more quickly by using this method.

[0032] Both sides of the linkage part extend outward to form a slider 44 for limiting the push button from leaving the lighter body. The slider and the shell form a limit fit to maintain the push button always in contact with the shell and enable the push button to only move up and down.

[0033] There is an annular structure 14 above the replacement port, and a plurality of scale lines 3 are arranged on the outside of the annular structure. The scale lines are used to indicate the wear and tear of the flint, and the scale lines are used in conjunction with a push button. When the flint is worn out, the push button will move upward under the action of a spring, and as it gradually moves upward, it will gradually cover the corresponding scale lines. The user can know the current wear and tear of the flint by observing the scale lines outside the push button, and can replace the flint in time, without having to look for the flint everywhere when needed, or being unable to use it when going out.

[0034] The scale lines are arranged in an array along the moving direction of the flint, and are arranged corresponding to the moving direction of the flint, so as to more accurately know the wear and tear of the flint.

[0035] The push button is also provided with a plurality of concave and convex surfaces 46 on its surface to increase the friction of the push button and make it more convenient to use.

[0036] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
