Description

[Detailed description of the invention] <Industrial application field> This invention uses various interval timers,
This invention relates to an improvement of an intermittent aerosol injection device that is used to maintain a constant indoor environment by continuously injecting an aerosol liquid for a certain period of time intermittently.

<Conventional technology> Intermittent aerosol injection devices that use a timer to maintain a constant indoor environment by continuously injecting aerosol liquid for a certain period of time have existed for a long time. It was designed to suck up and spray a chemical solution.

<Problem that the invention seeks to solve> However, even though this product is small, its size is
Not only is it large at 15 x 24 x 35 cm, but it is also heavy.
It was heavy at 5.8 kg and also expensive at about 200,000 yen, making it difficult to use in small stores or ordinary households.

The present invention aims to solve the above problems and provide an intermittent aerosol injection device that can be used in general households.

<Means to solve the problem> Interval timer 12 that outputs signals intermittently
2a, and a timer 1 that operates the relay 122c for a certain period of time based on the signal from the interval timer 122a.
22b, a relay 122c that passes current through the solenoid 121 in response to a signal from a timer 122b, a solenoid 121 that operates the injection valve of the aerosol can 10, and the aerosol can 10, so as to continue intermittently injecting for a certain period of time. Solved the problem.

<Operation> The timer 122b is operated intermittently using the interval timer 122a.

The timer 122b is a predetermined time relay 122c.
Continue to send a signal to relay 1 while sending the signal.
Keep 22c ON.

The relay 122c in the ON state causes current to flow through the solenoid 121, attracting the movable iron core 121a in the solenoid 121, and causing the aerosol can 10 to
Activate the injection valve.

When the signal from the timer 122b is interrupted, the self-restoring force of the injection valve returns the injection valve to its original position and injection is stopped.

<Embodiment> FIG. 1 is a partially cutaway side view showing an air freshener injection device which is a preferred embodiment of this invention, and FIG. 2 is a circuit diagram of FIG. 1.

A detailed description will be given below with reference to this drawing. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this example are not intended to limit the scope of this invention, unless specifically stated. , is merely an illustrative example.

The fragrance spraying device of this embodiment is used by being fixed to the upper part of the wall 1 with nails or double-sided tape (not shown) as appropriate.

The injection device is divided into a main body and an aerosol can 10, and the upper end 11 and lower end 12 of the aerosol can 10 are removably engaged with a locking part protruding from a case 110 of the main body. When the aerosol liquid runs out, the entire aerosol can 10 is replaced.

The aerosol can 10 has a generally commercially available tilt valve (tilt operating valve) structure, and a nozzle 14 is mounted on a stem 13 at the tip of the valve.

The main body includes a case 110 and a drive device that operates the injection valve of the aerosol can 10.

The drive device includes a solenoid 121, an electronic circuit section 122, a dry battery 123, and a switch 125.

The solenoid 121 is a coil having a movable iron core 121a, and the right end of the movable iron core 121a in the drawing is connected to the nozzle 14 of the aerosol can 10 via a locking tool. The locking tools in this embodiment are a hook 15 and a wire 16 provided on the side surface of the nozzle 14.

The electronic circuit section 122 includes an interval timer 122a and a timer 122b as shown in FIG.
and a relay 122c, and the relay 122c uses an NPN type transistor in this example.

Then, the dry battery 123 is connected to the interval timer 122a through the switch 125, the interval timer 122a is connected to the timer 122b, the timer 122b is connected to the relay 122c, and the relay 122
c is connected to a solenoid 121, and the solenoid 121 is connected to a dry battery 123.

Next, the operating state when the switch 125 is turned on will be explained.

a The interval timer 122a operates and issues a signal.

b The signal of interval timer 122a activates timer 122b.

c The timer 122b applies a current to the base side of the transistor, which is a relay, for a certain period of time.

d The transistor turns on and current begins to flow from the collector side to the emitter side.

e The solenoid 121 is energized, and the movable iron core 12
Pull 1a to the left as shown in Figure 1.

f The nozzle 14 of the aerosol can 10 is the movable iron core 1
21a is pulled and the tail valve opens.

g Aerosol liquid is sprayed from the nozzle 14.

h After a certain period of time, the timer 122b stops applying current to the base side of the transistor.

i The transistor turns OFF and current no longer flows from the collector side to the emitter side.

j The energization of the solenoid 121 is stopped, and the force that pulls the movable iron core 121a toward the center of the coil (leftward as shown in FIG. 1) disappears.

k The nozzle 14 of the aerosol can 10 moves to the right in FIG. 1 due to its self-restoring force and returns to its original position, stopping the injection.

l From then on, the interval timer 122
a is activated and the above operation is performed by turning switch 125.
Continue until you turn it off.

The injector of the present invention thus constructed is an intermittent aerosol injector that continues to inject at regular intervals for a predetermined period of time.

It goes without saying that the interval timer of this embodiment may be appropriately selected from commercially available ones, and the injection time and the setting time of the injection interval may also be changed depending on the purpose. Alternatively, the tail valve may be replaced with another valve, and the mounting direction of the solenoid may be changed accordingly.

For reference, the following are possible uses of the present invention.

(a) Air freshener spray that is sprayed at regular intervals in public restrooms (b) Disinfectant spray that is used in small food factories and cafeterias when unattended to maintain a certain level of sanitary conditions (c) Constantly eliminates room odors A deodorant spray that maintains a constant state <Effects of the invention> The intermittent aerosol spray device of this invention sprays aerosol liquid from the nozzle at regular intervals for a fixed period of time, so just by turning on the switch, it is safe for people. To provide a useful and practical aerosol intermittent injection device capable of keeping a room in a constant state at all times without bothering the operator.
