The flashlight further includes a flashlight tail 3 connected to another end of the flashlight body 1 away from the lamp base 2, a control assembly fixedly provided inside the flashlight tail 3 and in signal connection with a lamp bead driving circuit and the illumination switch 7 respectively, and a toggle switch 5 slidably mounted on an outer side of the flashlight tail 3 and provided with at least two gears in a direction parallel to an axial direction of the flashlight body 1, where the toggle switch 5 is configured to toggle in a reciprocating manner between the two adjacent gears so as to transmit a locking signal or an unlocking signal to the control assembly, and when the control assembly receives the locking signal from the toggle switch 5, the control assembly transmits a disconnection instruction to the lamp bead driving circuit; and when the control assembly receives the unlocking signal from the toggle switch 5, the control assembly recognizes a switch signal of the illumination switch 7 and transmits a connection instruction or the disconnection instruction to the lamp bead driving circuit according to a recognition result.

During practical application of this embodiment, by pushing the toggle switch 5 provided on the flashlight tail 3, switching of the different gears is achieved and a corresponding signal is transmitted to the control assembly, and after receiving the corresponding signal, the control assembly performs adjustment and outputs a corresponding instruction, thereby connecting or disconnecting the lamp bead driving circuit, and then achieving one-key locking of the illumination switch 7 of the flashlight. After locking, the lamp bead cannot emit light no matter whether a user presses the illumination switch 7 of the flashlight, thereby avoiding power waste caused when the user touches the illumination switch 7 by mistake; in addition, by means of the toggle switch 5 located on the flashlight tail 3 and capable of moving in the direction parallel to the axial direction of the flashlight body 1, when the flashlight body 1 is held by one hand, the gears can be changed by pushing the toggle switch 5 directly in the axial direction of the flashlight body 1, then one-key locking of the flashlight can be achieved, the operation process is relatively convenient, and use requirements of the user can be met.

It should be noted that, as shown in FIGS. 7 and 8, which correspond to structure diagrams of the flashlight in an unlocked state and in a locked state in sequence, when the lamp bead driving circuit is locked, the illumination switch 7 of the flashlight is also disabled, thereby achieving one-key locking of the flashlight.

In one case of this embodiment, the gears of the toggle switch 5 can be set as required, thereby achieving the states of the lamp bead driving circuit in correspondence to the different gears, for example, in addition to connecting and disconnecting the lamp bead driving circuit, the different gears can also correspond to different brightness or colors of the lamp bead, and thus the number of the gears of the toggle switch 5 is not specified restrictively.

During practical application of this embodiment, the control assembly includes an MCU and a Hall sensor 4 which are fixedly provided inside the flashlight tail 3. The Hall sensor 4 is electrically connected to the MCU, the MCU is in signal connection with the lamp bead driving circuit and the illumination switch 7 respectively, the toggle switch 5 is disposed close to the Hall sensor 4 and is configured to change an external magnetic field of the Hall sensor so as to change a voltage signal transmitted to the MCU by the Hall sensor 4, and the MCU is configured to recognize the locking signal or the unlocking signal according to different voltage signals.

It can be seen that the external magnetic field of the Hall sensor 4 is changed by means of the toggle switch 5, then the voltage signal transmitted to the MCU by the Hall sensor 4 is changed, and the MCU can recognize the locking signal or the unlocking signal according to the different voltage signals, thereby connecting or disconnecting the lamp bead driving circuit.

It can be seen that by means of the sliding groove 6 formed in the flashlight tail 3, the toggle switch 5 can be mounted conveniently, and the toggle direction thereof can be limited, thereby ensuring that the actual toggle direction is parallel to the axial direction of the flashlight body 1; and the toggle switch 5 is in contact with the inner walls of the two sides of the sliding groove 6 respectively, thereby achieving switching of the two gears, which correspond to unlocking and locking of the flashlight.

Further, as shown in FIGS. 5 and 6, the toggle switch 5 includes a toggle key 51, a magnetic block 52 and a gear slider 53 which are sequentially connected from outside to inside, the gear slider 53 is slidably mounted inside the sliding groove 6, and an outer side wall of the toggle key 51 is exposed out of an end port of the sliding groove 6.

Further, the sliding groove 6 includes a first square groove 61 and a second square groove 62 which are sequentially connected from outside to inside and have lengthwise directions parallel to the axial direction of the flashlight body 1. The length of the first square groove 61 is less than the length of the second square groove 62, and the width of the first square groove 61 is less than the width of the second square groove 62. The gear slider 53 is slidably connected inside the second square groove 62, outer walls of two sides of the gear slider respectively abut against inner walls of two sides of the second square groove 62 in a widthwise direction, and outer walls of another two sides of the gear slider are configured to be in contact with inner walls of two sides of the second square groove 62 in a lengthwise direction respectively so as to achieve change of the magnetic field of the Hall sensor 4; and the outer side wall of the toggle key 51 is exposed out of the first square groove 61.

It can be seen that the toggle switch 5 is configured to include the toggle key 51, the magnetic block 52 and the gear slider 53 which are assembled sequentially, and the gear slider 53 slidably abuts against the inner walls of the two sides of the second square groove 62 in the widthwise direction, such that the entire toggle switch 5 reciprocates in the direction parallel to the axial direction of the flashlight body 1, and there is a certain pre-tightening force with the inner walls of the two sides, which prevents the gear slider 53 from moving freely in an unrestrained manner inside the second square groove 62; and the inner walls of the two sides of the second square groove 62 in the lengthwise direction can sequentially correspond to the two gears of the toggle switch 5, thereby achieving switching of the two states.

It should be noted that the Hall sensor 4 can be subjected to magnetic induction with the magnetic block 52 of the toggle switch 5. The toggle switch 5 drives the magnetic block 52 to move in the toggle process, the Hall sensor 4 detects the change of the magnetic field so as to convert a changed magnetic field signal into the voltage signal and output the same to the MCU, the MCU can detect the position of the toggle switch 5 after processing the voltage signal and can receive the locking signal or the unlocking signal of the toggle switch, in combination with a digital signal of the illumination switch 7, after program logic operation, the MCU can obtain an instruction for controlling connection and disconnection of the lamp bead driving circuit and transmit the instruction to the lamp bead driving circuit, thereby adjusting the working state thereof, and achieving connection and disconnection of the lamp bead driving circuit.

As an example, in this embodiment, signal transmission can be performed on the MCU by means of a toggle stop block and an optical sensor, thereby transmitting the locking signal or the unlocking signal. An external signal transmission element can also be used to transmit the locking signal or the unlocking signal to the MCU, and then the MCU further recognizes and judges the digital signal of the illumination switch 7 so as to determine transmission of the connection instruction or the disconnection instruction to the lamp bead driving circuit. Therefore, the transmission manner for the locking signal and the unlocking signal is not specified restrictively in this embodiment.
