Description

[Detailed description of the invention] This invention relates to a portable electric sprayer that uses a pump to draw up liquid in a container, pressurizes it, and sprays it from a spray nozzle.The power battery and spray nozzle can be easily replaced. The purpose is to provide structure.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

1 to 3, 1 is a container for storing liquid, 2 is a container for storing liquid,
Reference numeral 3 indicates a pump that sucks up and pressurizes the liquid in the container 1, and 3 indicates a drive device that drives the pump 2. Power from a motor 4 is transmitted to the pump 2 via a drive mechanism 5.

6, 6 A power supply battery for driving the drive device 3, 7 is the container 1
A box which is installed above and houses the pump 2, the drive device 3 button and the power battery 6°6', and the box 7 is integrally formed with a partition wall 8 that partitions the inside of the box 7 into upper and lower parts. are doing.

Further, the pump 2 has a discharge port 9 facing the partition wall 8, and a spray nozzle 10 is detachably attached to the discharge port 9.

Reference numeral 11 denotes an ejection window provided on the circumferential surface of the box 7;
The spray nozzle 10 is facing toward the front.

Reference numeral 12 denotes an insertion opening for the power batteries 6, 6' formed in the partition wall 8, from which the power batteries 6, 6' protrude upward.

13 is a spray nozzle 10, a power supply battery 6, a motor 4
f: A lid removably attached to the case 7 so as to cover it, and its attachment/detachment structure is such that the lid 13 is provided with a protrusion 14 and the case 7 is provided with a recess 15, and the two are elastically engaged. I try to let them do it.

16 is an elastic switch plate provided on the lid 13 so as to correspond to the power batteries 6, 6'; one end of this switch plate 16 contacts the positive electrode 17, and the other end contacts the lid 13.
A push button 18, which is vertically slidably held at 3, is always urged upward.

Further, the lid body 13 is designed so that a predetermined gap 20 is maintained between the tip 1σ of the switch plate 16 and the negative side electrode 19.
A protrusion 21 that protrudes downward is integrally formed.

Reference numeral 22 denotes a lip formed integrally with the lid body 13 to prevent the spray nozzle 10 from being removed.

The spraying operation of the above configuration will be explained.

When the push button 18 is pressed, the tip 16' of the switch plate 16 comes into contact with the negative electrode 19 of the power battery 6', and the motor 4
Powered by

The power of the motor 13 is then transmitted to the pump 2 via the drive mechanism 5 to operate the pump 2.

By operating the pump 2, the liquid in the container 1 is sucked up, pressurized, and atomized outward from the spray nozzle 10.

In this case, the nozzle opening of the spray nozzle 10 is made as small as possible because the sprayer is used for cosmetic sprays that require relatively fine spray.

Therefore, there are many cases where the nozzle opening is clogged and spraying cannot be performed.
Since the spray nozzle 10 is exposed, the spray nozzle 10 is removed.

In the above embodiment, the lid 13 is provided with a protrusion 14 and the case 7 is provided with a recess 15 to elastically engage the two, but conversely, the lid 13 is provided with a recess, In addition, a protrusion may be provided on the box 7 to elastically engage the two.

Further, although the push button 18 is held on the lid 13 so as to be slidable up and down, the push button 18 may be exposed to the side surface of the lid 13 or the case 7.

As described above, according to the present invention, a partition wall is formed that partitions the interior of the box into upper and lower parts, the power supply battery and the pump discharge port are exposed to this partition wall, and the spray nozzle is detachably attached to the pump discharge port. In addition, the lid is detachably attached to the case to cover the spray nozzle button and power battery, so if one of the spray nozzle ports becomes clogged, cleaning or replacing the battery can be done by simply removing the lid. It is something that can be done easily.
