1. A powder sprayer, comprising a sprayer body holding a powder in a powder bottle thereof and a dip tube in said powder bottle, and a spraying mechanism installed in said sprayer body and operable through an inflation bulb thereof to force said powder out of said sprayer body in a mist, wherein: said sprayer body comprises a bottle cap fastened to said powder bottle and a nozzle head mounted on a top side of said bottle cap, said bottle cap having a through hole vertically cut through top and bottom sides thereof for guiding in said powder from said powder bottle through said dip tube, said nozzle head having a transverse mounting hole transversely cut through the periphery thereof in communication with the through hole of said bottle cap and a guide notch located on the periphery at one end of said transverse mounting hole;said spraying mechanism comprises a nozzle tube positioned in said transverse mounting hole, said nozzle tube having a guide block protruding from the periphery thereof and fitting the guide notch of said nozzle head, an air passage axially cut through two distal ends thereof and connected to said inflation bulb and a transverse suction hole located on the periphery thereof and disposed in communication between said air passage and the through hole of said bottle cap for sucking said powder from said powder bottle through said dip tube into said air passage when said inflation bulb is compressed by a user to force air out of said inflation bulb through said air passage;wherein said bottle cap has a top neck upwardly protruded from a top side thereof around said through hole and a first endless rib protruded from and extending around the periphery thereof; said nozzle head having a bottom hole coupled to said top neck of said bottle cap and a first inside annular groove disposed in said bottom hole and forced into engagement with said first endless rib. 2. The powder sprayer as claimed in claim 1, wherein said dip tube has a top end connected to a bottom side of said bottle neck of bottle cap and a bottom end suspending in said powder bottle and inserted into said powder in said powder bottle. 3. A powder sprayer, comprising a sprayer body holding a powder in a powder bottle thereof and a dip tube in said powder bottle, and a spraying mechanism installed in said sprayer body and operable through an inflation bulb thereof to force said powder out of said sprayer body in a mist, wherein: said sprayer body comprises a bottle cap fastened to said powder bottle and a nozzle head mounted on a top side of said bottle cap, said bottle cap having a through hole vertically cut through top and bottom sides thereof for guiding in said powder from said powder bottle through said dip tube, said nozzle head having a transverse mounting hole transversely cut through the periphery thereof in communication with the through hole of said bottle cap and a guide notch located on the periphery at one end of said transverse mounting hole;said spraying mechanism comprises a nozzle tube positioned in said transverse mounting hole, said nozzle tube having a guide block protruding from the periphery thereof and fitting the guide notch of said nozzle head, an air passage axially cut through two distal ends thereof and connected to said inflation bulb and a transverse suction hole located on the periphery thereof and disposed in communication between said air passage and the through hole of said bottle cap for sucking said powder from said powder bottle through said dip tube into said air passage when said inflation bulb is compressed by a user to force air out of said inflation bulb through said air passage;wherein said nozzle head has an inside annular groove disposed in one end of said transverse mounting hole; said nozzle tube has an endless rib protruded from and extending around the periphery thereof and forced into engagement with said inside annular groove. 4. A powder sprayer, comprising a sprayer body holding a powder in a powder bottle thereof and a dip tube in said powder bottle, and a spraying mechanism installed in said sprayer body and operable through an inflation bulb thereof to force said powder out of said sprayer body in a mist, wherein: said sprayer body comprises a bottle cap fastened to said powder bottle and a nozzle head mounted on a top side of said bottle cap, said bottle cap having a through hole vertically cut through top and bottom sides thereof for guiding in said powder from said powder bottle through said dip tube, said nozzle head having a transverse mounting hole transversely cut through the periphery thereof in communication with the through hole of said bottle cap and a guide notch located on the periphery at one end of said transverse mounting hole;said spraying mechanism comprises a nozzle tube positioned in said transverse mounting hole, said nozzle tube having a guide block protruding from the periphery thereof and fitting the guide notch of said nozzle head, an air passage axially cut through two distal ends thereof and connected to said inflation bulb and a transverse suction hole located on the periphery thereof and disposed in communication between said air passage and the through hole of said bottle cap for sucking said powder from said powder bottle through said dip tube into said air passage when said inflation bulb is compressed by a user to force air out of said inflation bulb through said air passage;wherein said spraying mechanism further comprises a connection tube that connects said inflation bulb to said nozzle tube, said connection tube having an endless rib protruded from and extending around the periphery thereof; said nozzle tube has an inside annular groove disposed in one end of said air passage and forced into engagement with said third endless rib. 5. The powder sprayer as claimed in claim 4, wherein said spraying mechanism further comprises a valve tube connected between said connection tube and said inflation bulb, said valve tube having an axial air hole extending through the two distal ends thereof and disposed in air communication between said inflation bulb and said connection tube, a stop flange protruded from an inside wall thereof near one end of said axial air hole and a constricted portion disposed at an opposite end of said axial air hole, and a ball moving in axial air hole of said valve tube between said top flange and said constricted portion for closing/opening said axial air hole subject to the operation status of said inflation bulb.
