Description

Technical Field

[0001] This utility model relates to the technical field of lighter refilling equipment, specifically to an automatic lighter refiller. Background Technology

[0002] A lighter is a small fire-starting device, mainly used for starting a fire, smoking, and also for cooking and other fire-starting purposes. The main components of a lighter are the ignition mechanism and the gas tank. When the ignition mechanism is activated, it emits a spark that shoots towards the gas compartment, igniting the gas. During the manufacturing process of a lighter, a gas filling device is needed to fill it with gas.

[0003] Existing automatic lighter refillers work by placing the lighter in a slot and having the operator hold a refill nozzle connected to the lighter to control the refilling mechanism. This method results in a fixed amount of gas being added, but because the operator is directly and completely exposed to the gas during refilling, there is a risk of sudden explosion. The lack of operator protection leads to a low safety factor and affects the device's usability. Therefore, there is an urgent need for an automatic lighter refiller to solve these problems.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1-3As shown, an automatic lighter refiller in this embodiment includes a gas canister 7 for storing gas. A metering pump 8 is installed on the output end of the gas canister 7 to refill the lighter with a fixed amount of gas. A gas guide tube 6 is connected to the output port of the gas canister 7, and one end of the gas guide tube 6 is connected to a refill nozzle 9, which can be connected to the lighter to refill it. A handheld rod 4 is fixed on one side wall of the refill nozzle 9. A telescopic protective plate 5 is provided on the handheld rod 4 to protect the operator. The protective plate 5 is transparent and has a built-in spring 12. An operation button 11 is installed on one side wall of the handheld rod 4 to control the operation of the metering pump 8.

[0024] like Figures 1-3 In this embodiment, the metering pump 8 is fixed to the output end of the gas tank 7 by bolts, the gas guide pipe 6 is connected to the gas tank 7 and the filling nozzle 9 by threads, the hand lever 4 is fixed to the filling nozzle 9 by screws, the operation button 11 is electrically connected to the metering pump 8, the protective plate 5 is fixed to the hand lever 4 by screws, and the spring 12 is welded between the fixed part and the telescopic part of the protective plate 5. The protective plate 5 has an arc-shaped structure. During the inflation process, the operator connects the filling nozzle 9 to the lighter through the hand lever 4, and then controls the metering pump 8 to work through the operation button 11, so that it quantitatively extracts the gas in the gas pipe 6 and injects it into the lighter through the gas guide pipe 6 and the filling nozzle 9, thereby inflating the lighter. During the inflation process, the telescopic protective plate 5 can ensure that its bottom end is always in contact with the support seat 2 under the action of the spring 12, thus effectively protecting the operator and avoiding injury caused by explosion. It also ensures the normal operation of the operator and effectively improves the safety and effectiveness of the device.

[0025] like Figures 1-3 In this embodiment, a gas injection nozzle 13 is reserved at the top of the gas tank 7, a bearing ring 10 is fixed on the outer wall of the gas tank 7, a support 1 is welded on one side wall of the bearing ring 10, the support 1 is an L-shaped structure, a bearing seat 2 is fixed at the upper end of the support 1, and a slot 3 is opened at the upper end of the bearing seat 2. The gas injection nozzle 13 facilitates the injection of gas into the gas tank 7, and the slot 3 can limit and fix the lighter.

[0026] The specific implementation process of this embodiment is as follows: Place the device in place and connect it to an external power source. During use, place the lighter in the slot 3 to limit and fix the lighter. Then, the operator connects the charging nozzle 9 to the lighter using the hand lever 4. Then, the metering pump 8 is controlled by the operation button 11 to extract the gas from the gas pipe 6 and inject it into the lighter through the gas pipe 6 and the charging nozzle 9, thus charging the lighter. During the charging process, the telescopic protective plate 5 can ensure that its bottom end is always in contact with the support seat 2 under the action of the spring 12. Thus, the protective plate 5 can effectively protect the operator and avoid injury caused by explosion. It also ensures the normal operation of the operator and effectively improves the safety and effectiveness of the device.
