A battery compartment 7 is provided on the side of the lighter body 1 away from the mounting groove 4, the battery compartment 7 is provided with a polarity contact spring corresponding to a storage battery 8, the storage battery 8 is movably connected inside the battery compartment 7, a compartment cover 9 is provided on one side of the battery compartment 7, a snap-fit component 10 is provided between the compartment cover 9 and the battery compartment 7, a transmission component 12 is provided on one side of the lighter body 1, and a prompting component 11 is provided on one side of the transmission component 12.
[0024] refer to Figure 1 The top of the blocking cover 5 is fixedly connected with an anti-slip protrusion 6, and there are multiple anti-slip protrusions 6. When it is necessary to slide the blocking cover 5, the operator's fingers come into contact with the multiple anti-slip protrusions 6 at the top of the blocking cover 5, increasing the friction. The operator can slide the blocking cover 5 with less effort and less slippage.
[0025] refer to Figure 2-3The snap-fit assembly 10 includes a slot 101 located inside the battery compartment 7. A snap-fit block 102 is engaged inside the slot 101, and one side of the snap-fit block 102 is fixedly connected to one side of the compartment cover 9. A slot 103 is located on the side of the battery compartment 7 away from the slot 101, and an insert block 104 is inserted into the slot 103. One side of the insert block 104 is fixedly connected to one side of the compartment cover 9. The snap-fit assembly 10 is thus used to secure the battery compartment 7. When installing the cover 9, align the locking block 102 on one side of the cover 9 with the slot 101 of the battery compartment 7 and insert it. At the same time, insert the plug 104 on the other side of the cover 9 into the slot 103 of the battery compartment 7. The cover 9 is connected to the battery compartment 7 by the engagement of the elastic locking block 102 with the elastic slot 101 and the insertion of the plug 104 with the slot 103. When removing the cover 9, apply external force to disengage the locking block 102 from the slot 101 and pull out the plug 104 to open the cover 9.
[0026] refer to Figure 5-6 The prompting component 11 includes a touch block 111, which is movably connected to one side of the cavity of the battery compartment 7 via a transmission component 12. A touch switch 112 is fixedly connected above the touch block 111 inside the cavity of the battery compartment 7. One side of the touch block 111 is movably connected to one side of the touch switch 112. A buzzer 113 is fixedly connected to one side of the lighter body 1. The transmission component 12 includes a sliding plate 122, which is slidably connected to one side of the internal cavity of the battery compartment 7. An arc block 121 is fixedly connected to the bottom end of the sliding plate 122. One side of the insert block 104 is movably connected to the arc block 121. A spring 123 is fixedly connected between the sliding plate 122 and one side of the cavity of the battery compartment 7. Guide grooves 126 are provided on both sides of the cavity of the battery compartment 7. A guide block 127 is slidably connected inside the guide groove 126. One side of the guide block 127... One side of the slide plate 122 is fixedly connected. By setting the prompt component 11 and the transmission component 12, when the compartment cover 9 is installed in place, the insert block 104 contacts the arc block 121 and pushes the slide plate 122 to compress the spring 123. The slide plate 122 maintains stable sliding under the restriction of the guide groove 126 and the guide block 127. When the compartment cover 9 is loose and not installed in place, the force of the insert block 104 on the arc block 121 decreases, the spring 123 resets and pushes the slide plate 122 to slide in the opposite direction, causing the touch block 111 to move. The touch block 111 does not contact the touch switch 112, the touch switch 112 becomes open, the alarm circuit where the buzzer 113 is located forms a circuit, triggering the buzzer 113 to emit an alarm sound to remind the user that the compartment cover 9 is installed abnormally. The touch block 111 contacts the touch switch 112. At this time, the touch switch 112 is in the closed state, the alarm circuit where the buzzer 113 is located is short-circuited, the current cannot flow through the buzzer 113, and the buzzer 113 does not work.
[0027] refer to Figure 5 The slide plate 122 is fixedly connected to both sides of the touch block 111. The battery compartment 7 is fixedly connected to both sides of the touch switch 112. One side of the balance bar 124 is slidably connected to one side of the balance sleeve 125. When the slide plate 122 slides, the balance bars 124 on both sides slide synchronously in the balance sleeve 125 inside the battery compartment 7, ensuring that the touch block 111 can accurately contact or separate from the touch switch 112.
[0028] Operating principle and advantages: If it is necessary to replace the battery 8, apply external force to disengage the locking block 102 on one side of the cover 9 from the slot 101 of the battery compartment 7, and at the same time pull out the plug 104 from the slot 103. After opening the cover 9, put the battery 8 into the battery compartment 7. The battery 8 will contact the battery 8 polarity contact spring in the battery compartment 7 to provide power. Then, reset the cover 9, so that the locking block 102 is engaged in the slot 101 and the plug 104 is inserted into the slot 103, completing the replacement and installation of the battery 8. At this time, the cover 9 is in place, the plug 104 contacts the arc block 121 in the transmission assembly 12 and pushes the slide plate 122 to compress the spring 123. The slide plate 122 slides stably under the restriction of the guide groove 126 and the guide block 127, causing the touch block 111 to contact the touch switch 112. The touch switch 112 is in the closed state, and the buzzer 1... When the alarm circuit containing 13 is short-circuited, buzzer 113 does not work. When the lighter needs to be used, the operator slides the blocking cover 5. The anti-slip ridge 6 at the top of the cover increases the friction, making the sliding easier. After the blocking cover 5 is removed, the push switch 3 is exposed. The push switch 3 can then be used to ignite the lighter head 2. When not in use, the blocking cover 5 is pushed back to cover the push switch 3, protecting it and preventing accidental activation. If the compartment cover 9 is loose or not properly installed during use, the force of the insert block 104 on the arc block 121 is reduced. The spring 123 resets and pushes the slide plate 122 to slide in the opposite direction, causing the contact block 111 to move. This separates the contact block 111 from the touch switch 112, and the touch switch 112 becomes open. The alarm circuit containing buzzer 113 is now open, and buzzer 113 sounds an alarm to remind the user to adjust the compartment cover 9.
