The arranged USB power supply unit 33a is located. A plurality of LED lamps (indicators) 34 indicating the remaining battery capacity of the generator 10 are arranged below the USB port. The user of the power generator 10 can check the remaining battery capacity by the number of lights of the LED lamp 34, and can easily identify the time to replace the power generator tank 40 and/or its components.

The USB power supply section 33a and the LED lamp 34 are surrounded by a peripheral wall 33b for protecting them. By arranging the USB power supply part 33a in the area surrounded by the peripheral wall 33b, even if the reaction liquid drips down to the front surface 10a side, it is possible to suppress the reaction liquid from directly entering the USB port. A port 37 for outputting a serial connection as a parallel connection is arranged on the side of the USB power supply section 33a.

The lid body 30 has a concave portion 35 extending rearward from the central portion on the upper surface 10c and extending in the vertical direction Y on the rear surface 10b. At the front end of the concave portion 35, an injection port for injecting the reaction liquid into the internal space S and an injection port cap 36 for sealing it are arranged.

In the present embodiment, since the water injection port is located in the recess 35 of the lid 30, even if the reaction liquid comes out of the water injection port when injecting the reaction liquid, the recess 35 serves as a barrier to the front surface. It is possible to prevent the reaction liquid from dripping down to 10a. Further, the reaction liquid that has flowed out into the recessed portion 35 of the lid 30 is guided downward by the recessed portion 22 of the case body 20 .

The generator power switch 14 is located on the front of the case body. Hooks 24 are arranged on the side of the first and second side surfaces 10e and 10f of the case body 20 so as to engage the fittings of the belt (shoulder belt) 15. As shown in FIG. The load capacity of the hook 24 is at least 15 kg or more, preferably 30 kg or more. The machine 10 can be safely carried in a suspended state.

In addition, the first side surface 10e of the first and second side surfaces 10e and 10f of the case main body 20 is provided with an intake port 25A for taking in outside air into the inside of the case main body 20. 10f is provided with an exhaust port 25B for discharging the air in the case body 20 to the outside.

A rear internal space S2 is formed between the rear face portion. That is, since the generator tank 40 and the case main body 20 are positioned apart from each other inside the generator 10, the reaction gas generated by the electrochemical reaction easily flows inside, thereby preventing the internal pressure from rising. In addition, it is possible to prevent the case body 20 from becoming hot due to heat generated by power generation.

In particular, since the USB power supply unit 33a is located on the front surface 10a of the case body 20, the case body 20 tends to become hot when the generator tank 40 is in contact with or close to the case body 20. By providing S1, such a situation can be suppressed. In the present embodiment, since the case body 20 has a shape that is convexly curved forward, the front internal space S1 can be formed larger than the rear internal space S2, and the front internal space S1 allows the case body 20 to move forward. It is possible to effectively suppress the front part side of the from being tinged with heat. In order to achieve such an effect, the distance between the front surface of the generator tank 40 and the front portion of the case body 20, that is, the dimension R of the front internal space S1 in the front-rear direction Z is 20% greater than the dimension in the front-rear direction Z of the generator 10. In the case of ~40 cm, it is at least 5 cm or more, preferably 5 to 15 cm.

In addition to providing the front and rear internal spaces S1 and S2 in the case main body 20, through holes may be formed in the front and rear surfaces 10a and 10b in order to prevent the case main body 20 from becoming hot. , a cooling fan may be placed.
