Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-4 are referred to, the utility model provides a kind of technical scheme：A kind of exhaust fan motor case, including upper shell
1st, lower house 5, motor mount 7, support supporting plate 12 and silencing cotton 14, the bottom of upper shell 1 are connected with junction button 2, and upper shell 1
Lower section is provided with connection housing 3, and the connection upper and lower ends of housing 3 are provided with O-ring seal 9, junction can be made more to have preferably
Sealing property, prevent lubricating oil and machine oil that motor internal uses etc. from leaking, connection housing is respectively and fixedly provided with company in both sides about 3
Access slot 4, the top of lower house 5 is provided with connection housing 3, and is provided with ventilation outside lower house 5, connection housing 3 and upper shell 1
Hole 6, motor mount 7 are externally connected to lower house 5, and connection housing 3 is internally provided with damping board slot 10, and in damping board slot 10
