The exhaust filter 15 has an outer shell portion 17. Filter unit 20 integrally inserted into the exhaust port 18 of the vehicle
Are configured.

With this structure, the joint between the exhaust filter 15 and the exhaust port 18 of the outer shell 17 can be kept completely airtight, and minute dust does not leak from the gap between the joints, and minute dust to the exhaust gas. Leakage can be prevented.

Further, since the exhaust filter 15 and the exhaust port 18 of the outer shell 17 are integrated, there is no need to provide a separate component for mounting the exhaust filter 15, and the vacuum cleaner body 11
Can be miniaturized.

Further, by providing a lattice-shaped molded product 33, which is a member having a ventilation performance, on the exhaust gas downstream side of the exhaust filter 15, the exhaust filter 15 integrally molded with the exhaust port 18 of the outer shell 17 is externally provided. It can be prevented from being easily damaged by a shock or pressure from.

Further, assembling work for assembling the exhaust filter 15 into the outer shell 17 is not necessary, the assembling cost can be reduced, and the shape of the exhaust filter 15 to be inserted is pleated so that the separator 19 for holding the pitch of the exhaust filter 15 is provided. It is also possible to mold it together with the lattice-shaped molded product 33, and by using a polymer filter material or HEPA filter material as the material, the purification effect can be improved and the exhaust pressure loss can be reduced, and a filter with high dust collection property. The unit can be configured.

[0031]

As described above, according to the present invention, by integrally forming the exhaust filter with the vacuum cleaner body forming component, the joint portion with the exhaust filter can be kept completely airtight, and the exhaust gas It is possible to prevent unnecessary dust leakage. Further, the complexity of assembling the electric vacuum cleaner and the assembling cost can be reduced.
