A hand powered liquid atomizer has a pistol-like housing with a union nut supported at the free, lower end of a handle part thereof so that the nut may be screwed onto a liquid vessel. The nut is supported on the housing by a holding part. The holding part is made of an elastic material and is stepped. It has a cylindrical part with a large diameter joined by a ring-like shoulder with a cylindrical headpiece having a middle hole and a diameter smaller than the large diameter. A pocket in the handle part of the housing is stepped in a way matching the step of the holding part, and has a first part which receives the cylindrical part of the holding part and which is joined by an annular step with a second part having a smaller diameter which receives the headpiece. The step has therethrough at least one air inlet hole which communicates with the outside air, and the shoulder has therethrough an air inlet hole which communicates with the inside of the vessel. In the space between the step and the shoulder there is an elastic annular diaphragm which is molded on and integral with the holding part in a manner so that the diaphragm is seated elastically on the annular step and covers the air inlet hole.
