As shown in FIG. 1, the various pressure relief valves 130 disclosed in the present invention (as described later) have the same effect, so that any one of the pressure relief holes 111 and/or the external pressure relief holes 121 can be used. The inner compartment 112 and the outer compartment 122 are kept sealed at ordinary times to maintain a waterproof and pressure-resistant state, and when the internal pressure rises, the pressure can be allowed to be discharged outward in a unidirectional manner.

In this way, when the battery 113 disposed inside the inner compartment 112 generates gas due to a charging/discharging effect or an abnormal condition, and a larger pressure is formed inside the inner compartment 112, the pressure will be more than a predetermined value. The inner pressure relief hole 111, the outer chamber 122 and the outer pressure relief hole 121 can be sequentially discharged to the outside of the outer casing 120.

As shown in FIG. 1 , the inner casing 110 is preferably composed of a first inner casing 114 and a second inner casing 115 , and the first inner casing 114 and the second inner casing 115 are sandwiched between each other. A first seal 116 is provided to ensure its tightness. Similarly, the outer casing 120 of the present invention preferably has a The first outer casing 123 and the second outer casing 124 are formed, and a second sealing member 125 is interposed between the first outer casing 123 and the second outer casing 124 to ensure the pressure resistance and the sealing property. As a result, the air density of the multiple pressure relief valve housing structures 100 can be effectively maintained by the arrangement of the first sealing member 116 and the second sealing member 125.

It should be noted that those skilled in the art can also easily drive the driving device 141, the transmission device 143 and the driven device 142 to other components, such as a motor-driven linkage device, and thus are not limited thereto.

The various aspects of the foregoing pressure relief valve 130 will be further described below.

Please refer to the first embodiment of the pressure relief valve shown in Fig. 3. It should be noted that in the first embodiment of the pressure relief valve shown in FIG. 3, the relief valve 130 is replaced by a pressure relief valve 200 for convenience of explanation.

As shown in FIG. 3, the first embodiment of the pressure relief valve 200 includes a first socket 210, a first elastic seal 220, a first spring member 230, and a first position restraining member 240.

The first socket 210 has an outer end 211 and an inner end 212 opposite to the outer end 211. The outer end 211 has a cover portion 211a extending radially outward, and the inner end 212 is disposed. The first elastic sealing member 220 is disposed on the lower side of the inner side of the outer end 211, and the first elastic member 230 is disposed on the annular groove 212a of the inner end 212, and the first position is restrained. The member 240 is disposed on the annular groove 212a of the inner end 212 and is used for clamping the first elastic member 230.

Therefore, when the pressure relief valve 200 is installed in the inner pressure relief hole 111 and/or the outer pressure relief hole 121 of the multiple pressure relief valve housing structure 100 as shown in FIG. 1, as shown in FIG.

Inward pulling force with the first position restraining member 240 against the first socket 210 causes the first socket 210 of the pressure relief valve 200 to be pushed away by the pressure from the inside to the outside, and the internal excessive pressure is self-induced The gap 250 is vented to the outside of the multiple pressure relief valve housing structure 100.

Preferably, as shown in Fig. 5, the gap 250 is formed with a slope 250a for multiple discharges when the first socket 210 of the pressure relief valve 200 is pushed upward by the aforementioned greater pressure from the inside to the outside. The gas inside the pressure valve housing structure 100 can be vented to the outside of the multiple pressure relief valve housing structure 100 in a smoother and more precise manner.

In addition, as shown in FIG. 3 , the first socket 210 of the pressure relief valve 200 further has a through hole 213 , and the through hole 213 extends through the outer end 211 and the inner end 212 of the first socket 210 , and the through hole A transparent plate 213a is disposed adjacent to the outer end 211 as an inspection window for viewing the inner side of the multiple pressure relief valve housing structure 100.

In addition, as shown in FIG. 3, in a preferred embodiment, the first elastic seal 220 of the pressure relief valve 200 is an O-ring, and the first elastic member 230 is a wave washer, and the first The one position restraint 240 is a C-type clasp, but is not intended to be a limitation of the present invention. In other words, those skilled in the art can easily associate other components having equivalent functions, and such equivalent elements can be the scope of the claimed invention.

The pressure valve housing structure 100 is exhausted. At the same time, external gases or liquids cannot enter. However, when the inner side of the multiple pressure relief valve housing structure 100 (eg, the inner compartment 112) is formed with a larger pressure, the pressure is suitable to push the second socket 320 and the second elastic member 330 to reduce the elastic seal. The member 340 is compressed such that gas having a high pressure can be discharged from the inner pressure relief holes 111 and/or the outer pressure relief holes 121 through the first opening 313 of the second position restraining member 310.
