Spray device

Abstract

A spray device includes a device body, an upper cover, and a movable member. The device body defines a mist generation chamber. The upper cover is connected to the device body and defines an installation cavity and a through hole, and the through hole is in communication with the installation cavity. The movable member is movably mounted in the installation cavity and is rotatable relative to the upper cover. The movable member is provided with a mist outlet being in communication with the mist generation chamber. At least a portion of the movable member is exposed to the installation cavity through the through hole. As the movable member rotates, the mist outlet is oriented in different directions.

         8 . The spray device according to  claim 1 , wherein the upper cover is removably connected to the device body. 
     
     
         9 . The spray device according to  claim 1 , wherein the movable member is configured with a contour that is at least partially spherical, the through hole is round hole, and a diameter of the through hole is smaller than a maximum radial dimension of the movable member. 
     
     
         10 . The spray device according to  claim 7 , wherein the cover plate and the mounting component are connected in a swivel snap way. 
     
     
         11 . The spray device according to  claim 3 , wherein the control handle abuts against an edge of the through hole when the movable member is rotated to a maximum extent. 
     
     
         12 . The spray device according to  claim 5 , wherein the movable member further defines a mist channel and an inlet, the inlet and the mist outlet are respectively arranged at substantially opposite ends of the mist channel, and a limiting edge is arranged around the inlet; the limiting surface abuts against the limiting edge when the movable member is rotated to a certain position. 
     
     
         13 . The spray device according to  claim 6 , wherein the obround hole of the mist outlet is curved. 
     
     
         14 . The spray device according to  claim 2 , wherein at least a portion of the first spherical surface where the mist outlet is located is exposed to the outside of the spray device through the through hole. 
     
     
         15 . The spray device according to  claim 14 , wherein as the movable member rotates, the mist outlet switches between states where it is not exposed through the through hole, partially exposed through the through hole, and fully exposed through the through hole. 
     
     
         16 . The spray device according to  claim 7 , wherein the device body further comprises housing that defined a second opening; the cover plate is mounted over the second opening.
