Detailed Description
Referring to fig. 1 to 9, a novel ventilation cap comprises a main body 3, the main body 3 is composed of a head portion located on the upper side and a tail portion located on the lower side, a chamber is arranged in the head portion, baffle plates 7 (two in the embodiment, oppositely arranged, and the number and arrangement form of the baffle plates can be arranged in other forms according to needs) for preventing oil splashing are arranged in the chamber, a plurality of locking portions 6 (four in the embodiment) are circumferentially arranged on the outer side of the head portion, the tail portion is used for connecting ventilation ports, an air passage is arranged inside the tail portion, and the air passage is communicated with the chamber.
The filter element 2 is mounted at the outlet of the chamber. The filter core is used for oil mist filtration.
The shell 1 is circumferentially provided with a plurality of locking ports (in the embodiment, 4 locking ports are rectangular ports), the shell 1 is buckled at the head of the main body 3, the locking part 6 is matched with the locking ports to realize locking, and an overflowing channel is arranged between the shell 1 and the head of the main body 3; wherein, gas flow channel is formed to air flue, cavity, filter core and flow passage.
In the embodiment, a connecting column 9 is arranged at the top of the air passage, the connecting column 9 is connected to the side wall of the air passage through a bracket, and the oil level monitoring pipe 8 is connected with the connecting column 9 (the connection mode includes but is not limited to threaded connection).
In the embodiment, the baffle 7 is arranged obliquely. The splash-proof structure is favorable for splash-proof, and simultaneously, the splashed oil liquid can flow back.
In the embodiment, the top of the outer side of the tail part is provided with a sealing gasket 4.
In an embodiment, the vent cap is attached to the vent port at its rear portion by threads 5, as shown in fig. 2. Or the tail part of the vent cap is matched with the O-shaped sealing ring 10 to be connected with the vent hole (directly pressed into the vent hole), and the installation state refers to fig. 4.
In the embodiment, the oil level monitoring pipe 8 is provided with oil level scales.
One way of assembling the vent cap is as follows: the filter element 2 is placed into the shell 1, the main body 3 is connected with the shell 1 through the locking part 6 matched with the locking port, then the sealing gasket 4 is installed, and finally the oil level monitoring pipe 8 is installed to complete the assembly.
The filter element 2 increases the oil mist filtering function of the ventilation cap. The baffle 7 increases the oil splash-proof function of the ventilation cap. The oil level monitoring pipe 8 has oil level scales, and can have different coordinates (scales) according to different bearing boxes and different liquid levels. The function of oil level monitoring of the ventilation cap is added.
