[Prior Art] For the switch of the flashlight used for diving, since the switch must be partially exposed outside the barrel for the user to operate, and partially disposed in the barrel to control the circuit of the flashlight to be electrically connected or disconnected, it is generally in the barrel The body forms a hole for the switch to pass through, but the disadvantage is that water is easily infiltrated into the flashlight from the switch. The diving flashlight of the existing push switch is disclosed in the Republic of China Patent No. 160151, which is a mounting hole for forming a switch in the barrel body, but because the barrel and the switch are not formed, even with a waterproof rubber pad The tightness is used to strengthen the watertight effect. When the switch is pressed, the water will seep from the pressing of the switch button. Especially when the water pressure is high, the button of the switch will not be able to return to the original position due to the pressure of the water, so that the operation cannot be continued. In order to improve the watertight effect of the switch, for example, the diving flashlight using the rotary switch disclosed in the Republic of China patent M261652, since the switch is disposed at the rear end of the barrel and conforms to the shape of the ring column of the barrel, only a majority of waterproofing is required. The apron can effectively block the infiltration of water from the switch, but the disadvantage is that the two hands must be operated 'but the diving equipment must be operated at the same time', which is inconvenient to use.

The rear cover 22 has a base wall 221, a ring wall 222 extending from the base wall 221 away from the tubular body 21, and a lean wall 221 On the contrary, the annular wall 222 extends in the direction of the tubular body 21 and can be separately screwed to the surrounding wall 223 of the tubular body 21 and the through hole 224 of the annular wall 222. The surrounding wall 223 ′ The tube body 21 cooperates to define the first space 23, and in this example, a waterproof rubber ring 2〇〇 is disposed on the surface of the wall 223 of the rear cover 22 and the barrel body 21, thereby making the first A space 23 achieves a better watertight effect, and in addition, only two perforations 224 can be illustrated in Figure 1 due to the graphical perspective. 5 M399939 The light source unit 3 is disposed in the first space 23 away from the back cover, and emits light when the electrical connection unit 4 receives the electrical energy of the power storage device 100 received in the first space 23, and the emitted light passes through The tube body 21 is incident on the outside, the electrical connection unit 4 is connected to the light source unit 3 and the power storage unit 1 is disposed in the first space 23, and the light source unit 3, the electrical connection unit 4, the A circuit in which the switching unit 5 is controllably electrically connected is formed between the electric storage devices 1 . The 6-Hui switch unit 5 includes a magnetic 51, a resilient member 52, and a circuit board 53. One end of the elastic member 52 abuts against the base wall 221 of the rear cover 22, and the other end is embedded with the bottom edge of the button 5丨; in this example, the elastic member 52 is made of a non-metallic and elastic material. Made of, for example, rubber or silicone, to avoid rust and facilitate the use of water. The bottom edge of the button 5 靠 is abutted against the ring wall 222 of the rear cover 22, and defines a second space 5 连通 with the base wall 221 and the ring wall 222 communicating with the outside through the three through holes 224. The circuit board 53 is disposed in the first space 23 adjacent to the base wall 221, and is electrically connected to the power storage unit 10A and the light source unit 3 by the electrical connection unit 4 to make the two units 3 and 4 It can be electrically connected or disconnected in a controlled manner. The button 51 can be in a first position X1 which is adjacent to the base wall 221 of the rear cover 22 and causes the circuit board 53 to induce a magnetic force, and a second position away from the base wall 221 and the circuit board 53 cannot sense the magnetic force. χ 2 displacements, and returning from the first position XI to the second position X2 by the restoring force accumulated when the elastic member 52 is deformed. When the button 51 is displaced to cause the circuit board 53 to induce a magnetic force, the electrical connection unit 4 and the light source unit 3 can be switched between the on and off states of the electric 6 M399939, so that the light source unit 3 is electrically connected. In the state, the light is received by the electric energy, or the light is stopped when the electric power is not received in the disconnected state. The flashlight with the magnetic switch mainly uses the button 51 and the circuit board 53 respectively located outside and outside the barrel unit 2, and controls the light source unit 3 at intervals through the magnetic induction of the button 51.
