Abstract

Provided is a sprayer usable as a cosmetic mist device and an inhaler. The sprayer includes an air pump, a motor, a battery, a mist nozzle, a tank for storing a mist liquid concentrate, and a vertically long, cylindrical, main body case. The main body case is divided into front and back chambers by a division wall, and the tank is housed in the front chamber. The air pump, the motor, and an electrical component section including the battery are disposed, in this order, in the back chamber. The tank is formed in a vertically long shape occupying most of the front chamber without affecting an outer shape of the main body case. A grip portion is formed in a recessed manner at an upper portion of a back face of the main body case and the air pump and the motor are disposed near the grip portion.

First claim

The invention claimed is:

1. A sprayer comprising:
a mist nozzle; a tank for storing a mist liquid concentrate; an air pump; a motor and a battery for driving the pump; and a main body case for housing these respective devices,
wherein the mist nozzle is supported by a nozzle case fixed in the main body case, and
an air supply opening of the mist nozzle and a discharge portion of the air pump are connected via an air supply tube,
wherein the nozzle case is formed by a left case body and a right case body which are two parts divided in a left-right direction, the mist nozzle is pinched and fixed by the left and right case bodies, and the left and right case bodies pinch a plurality of positions of an upper portion of an electrical component case to thereby integrate the electrical component case and the nozzle case into an actuation unit,
a middle portion of the air supply tube is pinched and fixed by a retaining hole provided in a junction between the left case body and the right case body so as not to move freely, and
wherein the actuation unit is detachably inserted and mounted into the main body case.

2. The sprayer according to claim 1 ,
wherein the nozzle case is mounted to an upper portion in the main body case, a switch operating member for switching a switch for the motor is disposed above the main body case, and
an upper wall of the nozzle case serves also as a switch base for supporting the switch operating member.

3. The sprayer according to claim 2 ,
wherein a seal body for sealing a switch window, which is open in the upper wall of the nozzle case, in a watertight manner is mounted to an opening edge of the switch window and
a switching operation by the switch operating member is transmitted to the switch via the seal body.

4. The sprayer according to claim 1 ,
wherein a coupling member, to which a connection portion provided to an upper portion of the tank is to be connected, is fixed to a lower end of the nozzle case,
the mist nozzle and the coupling member are connected via a liquid supply tube, and
bent passage portions are formed at two positions of a middle portion of the liquid supply tube so that a center of a connection between the mist nozzle and the liquid supply tube is positioned forward of a center of a connection between the coupling member and the liquid supply tube.

5. The sprayer according to claim 1 ,
wherein partition walls crossing the air supply tube are provided to the left case body and the right case body,
the retaining hole and a tube support wall for supporting the middle portion of the air supply tube are formed at a junction of the partition walls, and
the tube support wall guides the middle portion of the air supply tube in a curved manner to retain a bent portion of the air supply tube in a predetermined shape.

6. A sprayer comprising:
a mist nozzle; a tank for storing a mist liquid concentrate; an air pump; a motor and a battery for driving the pump; and a main body case for housing these respective devices,
wherein the mist nozzle is supported by a nozzle case fixed in the main body case,
wherein an air supply opening of the mist nozzle and a discharge portion of the air pump are connected via an air supply tube,
wherein an electrical component case is disposed below a back portion of the nozzle case,
wherein the air pump and the motor are mounted in an upper portion of the electrical component case,
wherein the air pump, the motor, the battery, and a circuit board are mounted in the electrical component case,
a fastening member fastens a left case body and a right case body of the nozzle case while both the case bodies pinch a plurality of positions of the upper portion of the electrical component case to thereby integrate the electrical component case and the nozzle case into an actuation unit, and
the actuation unit is detachably inserted and mounted into the main body case.

7. A sprayer comprising:
an air pump; a motor and a battery for driving the pump; a mist nozzle; a tank for storing a mist liquid concentrate; and a cylindrical main body case for housing these respective devices,
wherein a mist opening is open in an upper portion of a front wall of the main body case, the mist nozzle is disposed on an inner side of the mist opening,
the air pump for supplying pressurized air to the mist nozzle, the motor for driving the pump, and an electrical component section including the battery are disposed on a back half side in the main body case, and
the tank extending from a bottom portion of the main body case to a position below the mist nozzle is detachably housed on a front half side in the main body case;
wherein an inside of the main body case is divided into a front chamber on a front side and a back chamber on a back side by a division wall continuous in the vertical direction, the tank is housed in the front chamber, and the air pump, the motor, and the electrical component section including the battery are housed in the back chamber; and
wherein a coupling member, to which a connection portion provided to an upper portion of the tank is to be connected, is fixed to an upper end of the front chamber, and
a positioning portion, configured to receive a peripheral face of the tank and position the connection portion with respect to the coupling member, is formed on an inner face of an upper portion of the front chamber,
wherein an upper portion of the division wall is brought closer to the front wall of the main body case than the other portion of the division wall so as to form the positioning portion integrally with the division wall.

8. The sprayer according to claim 7 ,
wherein the mist nozzle and the tank are disposed on the front half side in the main body case, and the air pump, the motor, and the electrical component section are disposed on the back half side in the main body case, and
the tank is formed to be vertically long so that an upper end of the tank reaches a middle portion in a vertical direction of the air pump.

9. The sprayer according to claim 8 ,
wherein the air pump, the motor, and the electrical component section are disposed, in order from above, on the back half side in the main body case.

10. The sprayer according to claim 7 ,
wherein a front-back width in the back chamber is larger than a front-back width in the front chamber.

11. The sprayer according to claim 7
wherein a bottom lid for opening and closing a bottom opening of the main body case is provided to a lower end of the main body case,
