The utility model discloses a small experimental animal bladder water dilation perfusion device, which is provided with a T-shaped tee joint, a flat needle and a catheter, the rear end of the catheter sequentially penetrates through a left port and a right port of the T-shaped tee joint and is hermetically connected with the left port through a first pipe connecting piece, and the right port of the T-shaped tee joint is connected with a plug through a second pipe connecting piece. The plug is provided with an axial through hole, the rear end of the catheter penetrates through the second pipe connecting piece to be tightly inserted into the axial through hole, a needle head of the flat-end needle penetrates into the catheter through the through hole and penetrates out of the front end of the catheter, a water inlet hole is formed in the side wall of the front end of the catheter, and a water outlet hole is formed in the position, located at a lower through opening of the T-shaped tee joint, of the side wall of the catheter. And a lower port of the T-shaped tee joint is connected with a water outlet pipe through a third pipe connecting piece. Compared with the prior art, the device has the advantages of simplicity in operation, safety, reliability, accuracy in metering, high repeatability and the like.

This invention proposes an air guiding device and an energy storage system. The air guiding device includes a mounting component and an air guiding assembly. The mounting component has a mounting opening and includes a mounting structure adapted to connect to the energy storage device, and the mounting opening covers the heat dissipation opening. The air guiding assembly forms an air guiding channel, extending upwards from the center of the heat dissipation opening towards the center of the mounting opening. In this invention, because the air guiding channel extends obliquely upwards away from the ground, it helps to avoid adverse phenomena caused by the heat dissipation opening being located on the same side or concentrated with other airflow inlets or outlets of the energy storage device. Furthermore, since the air guiding device can be adapted to the energy storage device through the mounting structure, the installation and operation of the air guiding device are more convenient. Therefore, the air guiding device of this invention is easy to install and can improve the heat dissipation effect of the energy storage device.

The utility model relates to a cylinder assembly, pump body structure and compressor, cylinder assembly includes cylinder body, sliding block, the middle part of cylinder body is passed through its axial both ends and is provided with compression cavity, the inside wall of compression cavity is recessed and is formed with the sliding slot along the radial direction, the side of sliding slot away from compression cavity is spaced and is provided with the first cooperation part and the second cooperation part with the distance not equal with the center line of compression cavity along the axial direction, sliding block is slidably arranged in the sliding slot, the side surface of sliding block close to compression cavity is eccentric circular surface, the side of sliding block away from compression cavity is spaced and is provided with the first abutment of abutting with the first cooperation part and the second abutment of abutting with the second cooperation part along the axial direction, the utility model promotes the back pressure of sliding block through reducing the pressure of the end of sliding block and piston contact, and through the design of the first abutment and the second abutment of unequal length, prevent the adverse condition of reverse installation of sliding block, effectively solve the adverse phenomenon of "KATA" noise.
