Aspirator shell

The aspirator shell comprises a bottom shell and an upper shell which is assembled and connected with the bottom shell, a fixed bracket for positioning each component is arranged on the inner side, close to the upper shell, of the bottom shell; the fixed bracket is connected with the upper shell through a fastener; according to the technical scheme, the electronic devices are directly installed on the bottom shell of the aspirator, so that the electronic devices are directly positioned on the bottom shell in the assembling process, the electronic devices can be directly installed on the bottom shell of the aspirator, and therefore the electronic devices can be directly installed on the bottom shell of the aspirator in the assembling process. Meanwhile, wires related to electronic devices are directly connected with the sockets in the bottom shell in an inserted mode, after insertion is completed, the upper shell and the bottom shell are assembled and connected, the one-step assembly mode is high in assembly e
