Description

[Detailed explanation of the invention] A. Industrial application field This invention is applicable to restaurants, public halls, event halls,
This invention relates to a disinfection sprayer suitable for safely disinfecting relatively large rooms such as offices and warehouses in an unattended state.

B. Prior Art Conventionally, as a device for disinfecting relatively large rooms such as restaurants, public halls, event halls, offices, warehouses, etc., for example, as disclosed in Japanese Utility Model Application Publication No. 103445/1983, a chemical solution tank 7 has been used. A mount 2 is provided in which the holder can be freely accessed and removed, and an air outlet 12 with a bellows 13 is installed on the front.
A case 1 having a blower 6 on the back, an electromagnetic timer 34 and various switches 35, 36, 37 on the side, and a built-in flow regulating valve 10 mounted on the pedestal 2 is known. It's summery.

C. Problems to be solved by the invention In the above conventional example, the flow rate regulating valve 10 is interposed in the middle of the tube 11 through which the chemical solution 9 is fed, and
The operating switch 35 for the flow rate adjustment valve 10 was attached to the side of the case 1, and the spray test of the chemical solution 9 was conducted before the spraying operation to adjust the amount of spray, so there was no risk of the chemical solution 9 being inhaled into the human body. In addition, the case 1 becomes large and heavy due to the flow rate adjustment valve 10 and the operation switch 35, which increases the price, and there is a high risk of failure due to the equipment.
This was accompanied by other inconveniences.

D. Means for Solving the Problems In view of the above problems, the present invention provides a disinfectant sprayer that is small, lightweight, easy to carry, and inexpensive, which allows safe disinfection work without the need for a spray test. A tank case 6 is provided in which a chemical solution tank 7 is stored in a manner that it can be freely taken out and removed.A case 1 is provided with a spray port 4 opened in the front, a spray nozzle 3 is attached to the front, and a blower 2 is attached to the back. In the disinfection sprayer mounted on the sprayer, a supporting base 12 is provided on the inner surface side of the spray port 4, a tapered pipe 11a is formed on one side to which a hose 9 for feeding a chemical solution is connected, and a nozzle 10 is screwed on the other side. The approximate center of the joint 11, in which a screw rod 21 with a connection screw 11c is embedded, is fixed to the support base 12, and the center nozzle hole 10b has a different diameter and is screwed into the screw 11c of the joint 11 on the distal side. A plurality of nozzles 10 each having a cylinder 10d in which a fittable nut 20 is embedded, a hexagonal nut 10a is formed on the outside, and a tapered hole 10c communicating with the nozzle hole 10b is formed on the tip side.
The nozzle 10 is made replaceable by squarely fitting a box wrench 14 into the hexagonal nut 10a from the spray tube opening 3 of the case 1.

To replace the nozzle, first insert the tip of the box wrench into the nozzle's hexagonal nut through the front spray barrel opening, and turn it to the left.The nozzle will come off the joint screw.

Next, replace the removed nozzle with another nozzle tube with a different diameter into the box wrench, and screw it into place from the front spray tube opening to the thread of the insert joint while turning it to the right to make it ready for spraying.

EXAMPLE Hereinafter, one example of implementing the present invention will be described in detail based on the drawings.

1 is a case in which a blower 2 for supplying compressed air for spraying the chemical solution 13 is attached to the rear side, and a spray port 4 is attached to the front side to which the spray nozzle 3 for spraying the chemical solution 13 is attached.
is open, and a carrying handle 5 is fixed to the top surface.

Reference numeral 6 denotes a tank case on which the case 1 on the front side is mounted, and a chemical solution tank 7 is accommodated in a manner that it can be moved in and out, and leg pieces 8 are attached to the lower surface to buffer vibrations during spraying operations.

One end of the hose 9 and a nozzle 10 are installed inside the spray nozzle 3 attached to the spray nozzle 4 of the case 1.
A support base 12 of a joint 11 for connecting is fixed.

The hose 9, which has one end connected to the inside of the joint 11, has the other end connected to the chemical liquid tank 7 outside the case 1, and the air blown from the blower 2 causes the chemical liquid 13 in the tank to flow through the hose 9 and from the nozzle 10. Spray.

As shown in FIGS. 3 and 4, the joint 11 fixed to the support base 12 has a tapered pipe 11a formed on one side to which the hose 9 is connected, and a bulge 11b for fixation formed in the center. At the same time, a screw rod 21 having a screw 11c carved therein for screwingly connecting the nozzle 10 is buried in the other side.

On the other hand, the nozzle 10 that is threadedly connected to the joint 11 has a nut 20 that is threadedly connected to the thread 11c of the joint 11 on the distal side, as shown in FIGS. 3 and 5.
is buried and the outside thereof is covered with a hexagonal nut 10a.
A cylinder 10d is integrally formed with a nozzle hole 10b and a tapered hole 10c communicating with each other on the distal end side, and the chemical liquid 1 is discharged from the nozzle hole 10b.
3 is diffused and sprayed through the tapered hole 10c.

This nozzle 10 has several types with different diameters of the nozzle hole 10b (for example, 0.3, 0.35, 0.40, 0.45,
Prepare 5 types of 0.5mm).

The attachment and detachment of each nozzle 10 is performed by the third
As shown in the figure, the tip of the box wrench 14 is squarely fitted into the hexagonal nut 10a of the nozzle 10.

15 is a timer for operating the blower 2 attached to the side of the case 1 for a certain period of time; 16 is an electric cord connected to the blower 2 via the timer 15, and a plug 17 is connected to the tip.

G. Effect of the invention As described above, the disinfectant sprayer according to the invention allows various nozzles 10 with different diameters of the nozzle holes 10b to be easily replaced from the outside using the box wrench 14 without providing a flow rate adjustment valve inside the case 1. As a result, the entire sprayer can be made smaller and lighter, it can be manufactured at a lower cost, disinfection can be done without the need for dangerous spray adjustments, and the lighter weight makes it easier to carry. , has economic effects. In addition, since a flow rate regulating valve that is prone to failure is not used, reliable disinfection work can be performed.

Furthermore, since the screw rod 21 and nut 20 are separately provided for both the joint 11 and the nozzle 10, manufacturing is easy and the product cost is reduced.
