The radial direction oil return hole is two, is arranged symmetrically.
The air-cooled respirator of the utility model, may be implemented to prevent the lubricating oil splash in gear-box from coming out, and flowed to
In filter pulp, pollution of the waterproof lubricating oil to filter cotton, to influence respiratory function.
Detailed description of the invention
Fig. 1 is the appearance schematic diagram of air-cooled respirator；
Fig. 2 is the schematic diagram of the section structure of air-cooled respirator.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-2, a kind of air-cooled respirator including the threaded connector 3 for connecting with fuel tank and is used
In the filter cotton 5 filtered the air, the filter cotton is set in the lid 4 connecting with main body screw, the bottom of the lid
There is stomata 6 on face, the main body includes the outer tube 1 that an outer surface is formed with the cyclic annular radiating fin of integral type, described outer
The inside of casing is equipped with splashproof oil return pipe 2, and the outer wall of the splashproof oil return pipe 2 and being spaced apart for the inner wall of outer tube 1 are certain
Distance, to form the respiration channel 8 of air circulation, the external thread part and the screw thread that splashproof oil return pipe bottom end is formed connect
The internal thread part of connector 3 is threadedly coupled, the internal thread part of the bottom end of the external thread part and outer tube 1 of the threaded connector 3
It is connected, the internal thread part on the top of the outer tube 1 is connect with the external screw thread of top connection 7, and the lid 4 passes through the outer of protrusion
Threaded portion 41 is connect with the internal screw thread of top connection 7.
Wherein, it is formed with symmetrically on side opposite on the outer wall of the splashproof oil return pipe 2 to the threaded connector
Multiple spaced arc-shaped through-holes 21 up and down that direction is obliquely installed, the lower part of the outer wall of the splashproof oil return pipe is equipped with radial
Oil return hole 22, by blocking closing, lower end forms opening 23 for the upper end of the splashproof oil return pipe, for the circulation of air, realizes
The function of breathing.
Wherein, it is formed with drainback passage 9 between the outer wall of the splashproof oil return pipe and the inner wall of threaded connector, described time
Oily channel is communicated with the radial oil return hole 22.
Wherein, the external thread part that splashproof oil return pipe bottom end is formed is in the lower part of the radial oil return hole.
Wherein, the radial oil return hole 22 is two, is arranged symmetrically.
Air inside and outside fuel tank be connected through a screw thread first 3 (external screw thread on 31 side of opening of the nearly bottom end of threaded connector 3 with
Respirator mounting hole on fuel tank is threadedly coupled) opening 31 of bottom end, arc-shaped through-hole 21, respiration channel 8 through splashproof oil return pipe,
The through-hole of the centre of top connection 7, through-hole 11 and lid inside the external thread part 41 of the protrusion of lid are intracorporal to have through-hole 10
The partition for being used to support filter cotton 5, realize and communicated with extraneous air, realize and breathe.
It, can be logical from arc after the opening that lubricating oil is connected through a screw thread first 3 intermediate throughholes enters in splashproof oil return pipe
Hole 21 is flowed out, and is flow back into the opening 31 of the bottom end of the intermediate throughholes of threaded connector 3 downwards and by radial oil return hole 22, is returned
