Description

[Detailed description of the invention] This invention relates to an electric sprayer.

Conventionally, in sprayers, liquid and compressed gas are simultaneously sealed in a container and sprayed by pressing the nozzle, or compressed air is automatically supplied by turning a cylinder placed in the container upward or downward. However, with the former method, the container must be thrown away when the sprayed liquid is used up, which is uneconomical, and with the latter method, it is not necessary to refill the liquid. However, it has the drawbacks of being able to spray (use) only one type of liquid and having to move it upward many times, resulting in a failure rate.

The object of the present invention is to propose an electric sprayer that can eliminate the above-mentioned drawbacks, that is, a container containing a spraying liquid and a pump section that generates compressed air are formed separately, and they are The container is configured to be separably connected, and the container is provided with a liquid inlet and a spray nozzle,
The pump section has a built-in pump device operated by an electromagnet or a motor, and the connection section between the container and the pump section is provided with means for introducing compressed air generated by the pump device into the connected container. This is characterized in that the introduced compressed air is used to atomize the liquid.

Next, embodiments of the invention shown in the drawings will be described.

1 to 3 show three examples of electrical circuits for driving the electromagnet 9 of the atomizer shown in FIG. 4. FIG.

In the circuit of the embodiment shown in FIG. 1, the (-@ terminal of a DC power supply 1 and a pushbutton switch 2 are connected in series, and the other end of the pushbutton switch 2 is connected in series with a resistor 6 and a capacitor 5, and a relay Alternatively, the coil 4 of the reed relay 3 is connected in parallel.

The other terminal of capacitor 5 is relay or reed relay 3
The other end of the switch 7 is connected to one terminal of a DC power supply.

One end of the other normally open switch 8 is connected to the pushbutton switch 2 , and the other end is connected to the electromagnet 9 , and the other end of the electromagnet 9 is connected to the (→ terminal of the DC power supply 1 ).

In the circuit of FIG. 1, when push button switch 2 is pressed, current from DC power supply 1 flows through coil 4, a series circuit of capacitor 5 and resistor 6, and returns to DC power supply 1 via switch 7.

Initially, if there is no charge in the capacitor 5, a current flows through the coil 4 and a current suppressed by the resistor 6 flows through the capacitor 5.

The switch 7 is immediately opened by the magnetic action, but during this time, the capacitor 5 stores an electric charge, so that the electric charge stored in the capacitor 5 is discharged through the coil 4 and the resistor 6.

During this discharge, switch 8 is closed.

When discharged, the switch 7.8 returns to its original state due to the spring force applied to the relay or reed relay 3.

Then, switch 7 is closed and current flows to capacitor 5, which operates in the same manner as described above to oscillate and electromagnet 9 to operate continuously.

When the push button switch 2 is released, the current is no longer supplied and the above operation is stopped.

FIG. 2 shows another embodiment of the circuit.

This circuit connects the power source of an unstable multi-by break 10 to the (1) terminal of a DC power source 1 through a push button switch 2, and the output terminal of the un-stable multi-by break 10 is connected to the base of a transistor 12 through a resistor 11. It is connected to the.

The collector of the transistor 12 is connected to one end of the electromagnet 9, and the other end of the electromagnet 9 is connected to the (G) terminal of the push button switch 2.

The emitter is connected to the (to) terminal of the DC power supply 1.

In the embodiment of the circuit shown in FIG. 2, when the pushbutton switch 2 is pressed, the well-known unstable multi-vibration break 10 oscillates and a rectangular wave appears at the output terminal.

This output voltage activates the transistor 12 and continuously activates the electromagnet 9.

FIG. 3 shows another embodiment of the circuit.

In this circuit, a low voltage is generated from a commercial power source (100 V) using a transformer 13, a diode 14 is connected to one end of the low voltage coil, and a push button switch 2 and an electromagnet 9 are connected in series to form a closed circuit.

In the embodiment of FIG. 3, when the plug is inserted into the commercial power source, a low voltage is excited in the secondary coil of the transformer 13,
When the push button switch 2 is pressed in this state, the half-wave component is supplied to the electromagnet 9, and the electromagnet 9 is continuously operated.

The same effect can be achieved even without the transformer 13.

Next, a sprayer incorporating the above electric circuit will be explained with reference to FIG.

The atomizer consists of a liquid container 15 and a pump part 16.

In the container 15, an outer cylinder 17 and an inner cylinder 18 are welded all around at a portion a.

A tube 19 is fixed to the upper part of the outer cylinder 17, and a resin tube 20 is fitted to the lower end of the tube 19 and extends downward.

A diaphragm 28 is provided in the pump section 16 with its outer periphery sandwiched between a cylinder 29 and a plate 27 .

Further, the inner periphery of the diaphragm 28 has a shell 30 and a magnetic book 3.
1 and held airtight by rivets 32.

Thereby, the shell 30 and the magnetic body 31 are provided so as to be able to rise and fall freely, and are always urged upward by the spring 45.

At the center of the shell 30 and the magnetic body 31, a one-way valve 33 that allows ventilation only upward is provided, and a ventilation hole 34 is formed.

A disk 35 is fixed in the cylinder 29 by welding its periphery to the inner surface of the cylinder 29.

Above it is a cylinder 36, which is fixed to the disk 35 by welding.

A filter 37 is placed between the cylindrical body 29 and the cylinder 36 to prevent dust from entering.

Further, there are holes 38 around the cylindrical body 29 and the cylinder 36, so that air passes through the filter 37 and flows into the inner cylinder 36.

A U-shaped cylindrical magnetic body 39 is fixed to the lower surface of the disk 35, and a coil 40 is wound inside.

A board 41 incorporating the above-mentioned electric circuit is placed in the center of the cylinder 29, and a stopper 42 and a battery receiver welded to the cylinder 29 are fixed to the cylinder 43 so as not to move.

The receiver cylinder 43 is fitted into the cylinder body 29 so that it cannot easily slip out.

A lid 44 is fitted into the lower end of the cylindrical body 29 so that it can be easily removed by hand.

The lid 44 is for replacing the battery.

In the embodiment of the atomizer shown in FIG. 4, when the push button switch 2 is pressed, the electromagnet 9 is activated, the magnetic body 31 is attracted downward, and the upper chamber of the diaphragm 28 becomes under negative pressure.
As a result, the one-way valve 33 is opened and the air inside the cylinder body 29 is introduced into the upper chamber.

When the electromagnet 9 stops operating, the magnetic body 31 rises due to the action of the spring 45, the air in the upper chamber of the diaphragm is compressed, and the air is released through the hole 26 by opening the one-way valve 25 and flowing into the container 1.
It is supplied into the outer cylinder 17 of No. 5.

On the other hand, as the magnetic body 31 rises, external air flows from the hole 38 through the filter 37 and between the inner cylinders 36 to the magnetic body 31.
is introduced into the interior of the room.

By continuously pumping compressed air into the container 15 in this way, the inside of the container 15 is pressurized, and the liquid Bw in the container 15 is atomized through the throttle 22.

The same applies to the case where an AC power source is used, but it is necessary to use an AC motor as the motor 50.

Next, the effect will be explained.

When the switch 2 is pressed, a current flows from the DC power source 1 to the motor 50, the shaft 49 rotates, and the guide 46 moves up and down by the cam 48, causing the diaphragm 28 to move up and down, thereby acting as a pump.
