Liquid sprayer

Abstract

A transducer type liquid sprayer in which a storage tank for storing spray liquid can be easily replaced together with a core for soaking up the spray liquid from the storage tank is provided. The liquid sprayer includes a spray liquid storage unit and a main body for supporting the spray liquid storage unit and a power supply unit. The spray liquid storage unit includes a core for soaking up spray liquid and the main body includes a lid member attached to a support member for supporting the spray liquid storage unit so that the lid member can be opened and closed. A spray hole is formed in the lid member and a transducer is also disposed inside the lid member and electrically connected to the power supply unit. The transducer disposed inside the lid member is in close contact with and pressed against the core.

What is claimed is: 
     
         1 . A liquid sprayer for dispensing a spray liquid comprising:
 (a) a main body comprising:
 a support member having a back face, an upper portion, and a lower portion; 
 a power supply unit positioned on the upper portion of the support member; 
 a lid member having a front face, wherein the lid member is rotatably connected to the support member to an open position, which reveals the upper portion and lower portion of the support member, and a closed position; 
 a spray hole formed on the front face of the lid member; and 
   (b) a spray liquid storage unit which is supported by and positioned on the lower portion of the support member, the spray liquid storage unit comprising:
 a spray liquid housed in a storage tank; and 
 a core for soaking up spray liquid, wherein the spray liquid storage unit is removable from the main body when the lid member is in the open position; and 
   (c) a transducer disposed inside the lid member and electrically connected to the power supply unit, such that when the lid member is in the closed position, the transducer is in close contact with an pressed against a section of the core, and the core, transducer and spray hole are substantially aligned, such that when electric power is supplied from the power supply unit to the transducer, the spray liquid retained in the core is turned into a spray mist by vibration of the transducer and sprayed outside the main body through the spray hole.   
     
     
         2 . The liquid sprayer according to  claim 1  wherein when the lid member is in an open position, the upper portion and lower portion of the support member are revealed, and wherein when the lid member is in a closed position, the transducer disposed in the lid member is disposed parallel to a front face of the core. 
     
     
         3 . The liquid sprayer according to  claim 1  wherein the lid member further comprises side faces rising from opposite sides of the front face of the lid member, and wherein a support arm is positioned between opposite side faces of the lid member and the transducer is affixed to the support arm, which raises and lowers the transducer with lid member and aligns the transducer with the spray hole and core. 
     
     
         4 . The liquid sprayer according to  claim 1  wherein the support member further comprises one or more support members for supporting one or both of the power supply unit and the spray liquid storage unit. 
     
     
         5 . The liquid sprayer according to  claim 1  wherein the spray mist sprayed outside the main body through the spray hole is projected outside the main body in a substantially horizontal direction. 
     
     
         6 . The liquid sprayer according to  claim 1  wherein the spray mist comprises droplets from about 1 um to 10 um. 
     
     
         7 . The liquid sprayer according to  claim 1  wherein the spray mist comprises droplets of less than 7 um. 
     
     
         8 . The liquid sprayer according to  claim 1  wherein the lid member further comprises a lock hole, which restricts opening of the lid member. 
     
     
         9 . The liquid sprayer according to  claim 1  wherein the main body further comprises a key pad for setting automatic spray intervals for release of the spray mist. 
     
     
         10 . The liquid sprayer according to  claim 9  wherein key pad is an electronic display. 
     
     
         11 . The liquid sprayer according to  claim 1  wherein the main body further comprises a power indicator display. 
     
     
         12 . The liquid sprayer according to  claim 1  wherein the main body further comprises a light sensor for automatic turn off or turn on of the device. 
     
     
         13 . The liquid sprayer according to  claim 1 , wherein the spray liquid storage unit further comprises a cap for reducing evaporation of the spray liquid from the storage tank. 
     
     
         14 . The liquid sprayer according to  claim 1 , wherein the core comprises a tip end portion and a base end portion, the tip end portion including a front face to be in close contact with the transducer, and the base end portion extending from the tip end portion into the storage tank.
