As shown in FIGS. 1, 5, 6, 7 and 8, in order to facilitate opening of the compartment cover 4, a valve hole 13 is arranged at the upper wall of the compartment cover 4 and positioned between the two locking holes 5, and a lower wall of an inner side of the valve hole 13 is provided with a press type exhaust valve. The press type exhaust valve is composed of a joint 21, a valve housing 22, a press head 23, a sliding block 33 and a valve core 24, the joint 21 is fixedly connected to the lower wall of the inner side of the valve hole 13 in a penetrating manner, and a lower end of the joint 21 extends into the lower side of the compartment cover 4. The valve housing 22 is fixedly connected to an upper end of the joint 21, and a valve cavity is arranged inside the valve housing 22. An inner wall of the joint 21 is provided with a through hole penetrating up and down, the sliding block 33 is slidably connected inside the valve cavity, the valve core 24 is fixedly connected at a lower end of the sliding block 33, and the end, far away from the sliding block 33, of the valve core 24 penetrates an inner side wall of the through hole and is slidably connected to the through hole. The press head 23 is fixedly connected at an upper end of the sliding block 33, and the end, far away from the sliding block 33, of the press head 23 penetrates an upper wall of the valve housing 22 and extends out to an upper side of the valve housing 22. The portion, located inside the valve cavity, of an outer wall of the valve core 24 is provided with a spring 25 in a sleeved manner, and an upper end and a lower end of the spring 25 abut against a lower end of the sliding block 33 and an upper end of the joint 21 respectively. When the spring 25 is in a free state, a second air hole 28 is positioned inside the through hole, and when the spring 25 is pressed by pressing the press head 23, the second air hole 28 extends out to a lower side of the joint 21. The spring 25 acts to keep the sliding block 33 lifted when the press head 23 is not pressed, and to keep a cut-off state of the press type exhaust valve. The press type exhaust valve is arranged on the compartment cover 4, and when necessary, the press head 23 can be pressed to make the interior of the battery compartment 3 lose a negative pressure state due to entry of air, so as to open the compartment cover 4 conveniently.

As shown in FIGS. 7 and 8, in order to realize the press type exhaust and release type cut-off effects of the press type exhaust valve, a ventilation structure is arranged between the valve core 24 and the valve housing 22, and the ventilation structure includes a communication hole 26, a first air hole 27, the second air hole 28 and a third air hole 32. The communication hole 26 is arranged at an inner wall of the valve core 24, and the communication hole 26 does not penetrate a lower wall of the valve core 24. The first air hole 27 and the second air hole 28 are arranged at a side wall of the valve core 24 and are distributed up and down, and the ends, facing a center of the valve core 24, of the first air hole 27 and the second air hole 28 are in communication with the communication hole 26. The first air hole 27 and the second air hole 28 are close to an upper end and a lower end of the valve core 24 respectively, and the third air hole 32 is arranged at an outer wall of the valve housing 22 and is positioned at the end close to the joint 21. When the spring 25 is in the free state, the sliding block 33 is pushed up to an upward stroke. In this case, the second air hole 28 is located at the inner side wall of the through hole. A second sealing member 29 on the outer wall of the valve core 24 makes the interior of the battery compartment 3 sealed from the outside. When the press head 23 is pressed down to make the sliding block 33 move downwards, the valve core 24 is driven to move downward until the second air hole 28 is displaced below the joint 21. In this case, the interior of the battery compartment 3 is in communication with the outside through the second air hole 28, the communication hole 26, the first air hole 27 and the third air hole 32, and the external air quickly enters the interior of the battery compartment 3 through a passage, such that the negative pressure state inside the battery compartment 3 is lost, and the compartment cover 4 can be open by rotating the knob 6 to release the locking state between the locking tongue 18 and the locking block 19 in this case.

As shown in FIGS. 7 and 8, in order to keep the sealing property of the interior of the press type exhaust valve, a second sealing structure is arranged between the valve core 24 and the through hole and between the sliding block 33 and the inner side wall of the valve cavity. The second sealing structure includes two second sealing members 29, and the two second sealing members 29 are arranged on an outer wall of the valve core 24 and an outer wall of the sliding block 33 respectively. The second sealing member 29 on the outer wall of the valve core 24 is located at the position close to a lower end of the valve core 24, and an outer wall of the second sealing member 29 is in sliding connection to an inner side wall of the through hole. The second sealing member 29 on the outer wall of the sliding block 33 is located at the position close to the upper end of the sliding block 33, and an outer wall of the second sealing member 29 is in sliding connection to an inner side wall of the valve cavity. By means of the two sealing members 29, a sealing effect is achieved when the press type exhaust value is in the cut-off state.

As shown in FIG. 6, in order to form the negative pressure state inside the battery compartment 3, a first sealing structure is arranged between the knobs 6 and the locking holes 5, and between the compartment cover 4 and the battery compartment 3. The first sealing structure includes three first sealing members 16, and the three first sealing members 16 are arranged between the battery compartment 3 and the compartment cover 4, and between outer walls of the two knobs 6 and inner side walls of the two locking holes 5 respectively. Sealing between the battery compartment 3 and the compartment cover 4 and sealing between the knobs 6 and the locking holes 5 are achieved by the three first sealing members 16, and after the compartment cover 4 is closed, a sealed state is formed, such that negative pressure inside the battery compartment 3 is formed by means of suction of the vacuum pump 15.

As shown in FIGS. 1 and 6, in order to improve a waterproof effect of the battery compartment 3, a lower end of the vacuum suction pump 15 is detachably connected to the inner side wall of the valve hole 13, when the vacuum suction pump 15 is detachably connected to the inner side wall of the valve hole 13, the lower end of the vacuum suction pump 15 abuts against the upper end of the press head 23, and the interior of the battery compartment 3 is sucked into a negative pressure state by the vacuum pump 15. After the interior of the battery compartment 3 is sucked into the negative pressure state by the vacuum pump 15, external air pressure presses the battery compartment 3 and the compartment cover 4, such that the compartment cover 4 is more tightly combined with the battery compartment 3, thereby achieving a better waterproof effect.
