Description

Technical Field

[0002] The main components of a lighter are the ignition mechanism, gas tank, and casing. The ignition mechanism and gas tank are assembled in the casing, which protects them. When the ignition mechanism is activated, sparks fly towards the gas area, igniting the gas. The ignition mechanism is the most active part of the lighter's evolution and also the most complex in structure. Based on the characteristics of the ignition mechanism, lighters can be divided into flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters, microcomputer lighters, etc. The gas used in lighters is mainly flammable gas. In the early days, gasoline was mostly used. Today, butane, propane, and liquefied petroleum gas are commonly used. These gases are pressurized and filled into the gas tank. Once released into the air, they absorb heat, vaporize, and expand rapidly, making them extremely easy to ignite. Lighters are a ubiquitous sight in people's daily lives.

DETAILED DESCRIPTION

[0030] The present invention provides a casing structure and a lighter. To make the purpose, technical solution and effects of the present invention clearer and more specific, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0031] In the description of the present invention, it should be understood that the terms "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and should not be understood as limitations on the present invention. In addition, the terms "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figures 1 to 10 The present invention provides a shell structure, which includes a shell 1 for being sleeved on the outside of an ignition mechanism and an air storage box. A movable unit is provided on an outer side wall of the shell 1, and is characterized in that the movable unit includes a movable block assembly 2, a center plate 3, a spring assembly 5, an assembly plate 6 and a driving mechanism 7. The movable block assembly 2 and the center plate 3 are respectively arranged on the assembly plate 6 through the spring assembly 5, and the movable block assembly 2 is movably connected to the edge of the center plate 3 through the spring assembly 5. The assembly plate 6 is connected to the outer side wall of the shell 1. The driving mechanism 7 is provided on the shell 1, and the driving mechanism 7 is transmission-connected to the spring assembly 5. The driving mechanism 7 is used to drive the spring assembly 5 to perform telescopic movement, and the spring assembly 5 is used to drive the movable block assembly 2 to form a dynamic effect.

[0033] During actual use, the spring assembly 5 is driven to perform telescopic movement by operating the driving mechanism 7, so that the spring assembly 5 drives the movable block assembly 2 to form a dynamic effect. The shell structure is connected to the ignition mechanism through the shell 1 to form a lighter, making the lighter more functional and greatly improving the user experience.

[0034] In certain embodiments, in combination Figure 2 、 Figure 5 and Figure 7 It can be understood that an assembly groove 61 is provided on the assembly plate 6, and the center plate 3 and the movable block assembly 2 are respectively arranged in the assembly groove 61 through the spring assembly 5. The assembly groove 61 accommodates part of the structure of the center plate 3 and the movable block assembly 2 to prevent the center plate 3 and the movable block assembly 2 from protruding too much from the surface of the assembly plate 6. After the assembly plate 6 is installed on the shell 1, it does not affect the comfort of holding the shell 1.

[0035] In certain embodiments, as Figure 7 and Figure 8 As shown, a movable pressure block assembly 8 is provided on the center plate 3. The spring assembly 5 and the drive mechanism 7 are respectively connected to the pressure block assembly 8. The drive mechanism 7 is used to drive the pressure block assembly 8, which in turn causes the spring assembly 5 to extend and retract. During actual operation, the drive mechanism 7 drives the pressure block assembly 8 to exert pressure on the spring assembly 5, causing it to elastically deform. This elastic deformation of the spring assembly 5 then drives the movable block assembly 2 to create a dynamic effect.
