This utility model relates to the field of gearbox top cover technology and discloses a novel gearbox top cover, including a connecting straight pipe. The upper end of the connecting straight pipe is connected to the gearbox cover body by bolts. A nut is threaded onto the axial side wall of the bolts. A filter assembly for filtering grease is provided on the connecting straight pipe. A fixing assembly for clamping and fixing felt is provided on the connecting straight pipe. A discharge assembly for venting steam is provided on the gearbox cover body. Grease is filtered by a filter plate. Because the filter plate is inclined downwards, when there is too much grease on the filter plate, it will flow down due to gravity. When the grease leaves the filter plate, the weight of the filter plate decreases. At this time, the torsion spring will cause the filter plate to vibrate, thereby shaking the grease off the filter plate and preventing the filter plate from being filled with grease, which would affect the filtration effect.

The invention provides a liquid storage part and an electronic atomization device, and relates to the technical field of electronic atomization. The liquid storage part is used for the electronic atomization device and comprises a liquid storage bin and a ventilation part. A liquid storage cavity is formed in the liquid storage bin, the liquid storage cavity is used for storing an aerosol generating substrate, and the liquid storage bin is provided with a liquid outlet and a ventilation port which are communicated with the outside; the ventilation part comprises a ventilation pipeline, one end of the ventilation pipeline communicates with the ventilation opening, and the other end of the ventilation pipeline communicates with the liquid storage cavity through airflow. According to the liquid storage part provided by the invention, in the process that the aerosol generating matrix in the liquid storage bin is discharged through the liquid outlet for use, along with the reduction of liquid in the liquid storage bin, airflow of external atmosphere can enter the liquid storage bin through the ventilation port and the ventilation channel to perform automatic supplementation, so that the air pressure in the liquid storage bin can be effectively maintained to be the same as the atmospheric pressure; smooth liquid supply of the liquid storage part is ensured, and the use experience of a user is ensured.

The utility model discloses a pressure-equalizing air distribution disc which is provided with an inner air channel and an outer air channel, the inner air channel extends up and down, the outer air channel is annularly arranged outside the inner air channel, the outer air channel is communicated with the inner air channel through a communication port, a baffle is arranged in the outer air channel, the baffle extends outwards from the upper side of the communication port, and the baffle and the lower wall of the outer air channel are arranged at intervals to form a pressurization space. The baffle is provided with a vertically-extending air passing hole. The baffle is arranged in the outer air channel, the baffle extends outwards from the upper side of the communicating opening and is spaced from the lower wall of the outer air channel to form the pressurizing space, after air flows into the pressurizing space from the communicating opening, one part of the air flows into the position, away from the communicating opening, of the outer air channel towards the front / rear end of the baffle, and the other part of the air flows into the air outlet space through the air hole.
