The flow guide channel 24 is communicated with the main channel 22 and the auxiliary channel 23, and is used for discharging the liquid retained in the auxiliary channel 23 into the main channel 22, so that the liquid in the auxiliary channel 23 is continuously updated.
The pressure relief box of this embodiment can directly utilize the liquid that flows into in the auxiliary flow channel 23 to flow back to the main flow channel 22 and produce certain resistance to the liquid flow of the main flow channel 22 to prevent the liquid flow of the main flow channel 22 from being too urgent, thereby producing the pressure relief effect, the pressure relief effect of this structure is obvious, and the flow guiding channel 24 can solve the problem that some liquid remains in the auxiliary flow channel 23.

The cross-sectional area of the flow guide 24 of the present embodiment is smaller than the cross-sectional area of the secondary flow channel 23, which allows a large portion of the liquid flowing into the flow guide 24 to flow back into the primary flow channel 22 for imparting resistance to the flow of the liquid in the primary flow channel 22. The cross-sectional area here refers to the cross-sectional area of the flow channel perpendicular to the direction of liquid flow.
In some embodiments, as shown in fig. 3, the secondary flow channel 23 is a U-shaped flow channel that includes two opposing side channel portions and a curved channel portion that communicates the two side channel portions. The port of one of the side channel portions communicates with the main channel 22 as an inlet of the sub channel 23, and the port of the other side channel portion communicates with the main channel 22 as an outlet of the sub channel 23.
The inlet of the flow guide 24 communicates with the curved portion of the U-shaped flow channel, so that it is possible to prevent excessive liquid from remaining in the curved portion and being unable to be discharged.

Wherein the inlet of each secondary flow passage 23 is communicated with the upstream of the corresponding broken line segment, and the outlet is communicated with the downstream of the corresponding broken line segment, so that the secondary flow passages 23 can respectively decompress the liquid flowing in each broken line segment of the main flow passage 22.
In some embodiments, as shown in fig. 3, the number of the main channels 22 in the case is two, and the two main channels 22 are independent and symmetrical to each other. Therefore, the internal layout of the pressure relief box is more compact, and the volume is smaller.
