DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an optical detection device for a toilet seat sterilization device that sprays a chemical onto a toilet seat to sterilize it.

(Prior Art) In the past, several methods have been proposed regarding the sanitary use of toilet seats, but these have been accompanied by many problems in usability that should be improved.

(Problems to be Solved by the Invention) It is an object of the present invention to provide an optical detection device for a toilet seat sterilization device that solves the above-mentioned conventional problems and allows reliable detection and easy control.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention has the following features: 1. A device body attached to the rear of a toilet bowl, a light source and a light sensor provided on the device body to detect opening and closing of the toilet seat lid. This paper proposes an optical detection device for a toilet seat sterilization device consisting of:

(Function) (1) Since the device of the present invention optically detects opening and closing of the toilet seat cover, reliable detection is possible.

(2) Since the device of the present invention optically detects opening and closing of the toilet seat cover, control becomes easy.

(Example) The optical detection device of the toilet seat sterilization device of the present invention will be explained below according to the example shown in the drawings.

Figures 1 to 4 show the device of the invention, which has a device body (1) attached to the rear of a toilet bowl (91).

The device main body (1) consists of a bottom plate (2) made of polycarbonate resin or the like, and a cover (3) attached to the bottom plate (2) and made of ABS resin or the like.

Next, when the toilet seat lid (93) is opened, a light transmitting plate (4) is placed in the appropriate place on the cover (3) located on the back of the toilet seat lid (93).
is provided.

A film that allows light such as infrared light to pass through is attached to the light transmitting plate (4).

Further, inside the light transmitting plate (4), as shown in FIGS. 3 and 5, a light R (7) for emitting infrared rays and the like and a light sensor (8) for receiving the reflected light are provided.

Next, a pair of nozzles (2) are installed in both sides of the cover (3).
7) is placed and fixed.

The nozzle hole (28) of the nozzle (27) is positioned in the nozzle opening (5a) of the cover (3).

Next, a drug container (13) containing a drug such as a disinfectant under pressure (for example, 3 Kg/cm") is hung from one of both sides of the bottom plate (2). .

Next, as shown in FIG. 5, a control circuit (6) is provided, and the control circuit (6) is powered by a battery (IO) or a commercial power source.

The battery (10) is, for example, a 12V lead-acid battery (13V at the beginning of charging), and the voltage drop (for example, from 13V to 12V) is used.
When the voltage drops to V), a circuit is formed so that an alarm is issued by lighting up a light emitting diode F'D, and it is also possible to switch to a commercial power supply of 100 cm.

The control circuit (6) connects the light R (7) and the light sensor (8).
When it is detected that the toilet seat cover (93) is opened, the solenoid device (9) is actuated.

That is, as shown in Figs. 4 and 5, the solenoid device (
9) has a coil (9a) and a plunger (9b) which is moved by the excitation of the coil (9a) and whose tip is wrapped.

The thin tip of the plunger (9b) is a pressing body (23) (
(See Figure 7) through the stem (14) of the drug container (13).
).

The stem (14) is fitted with a spring (21) as shown in detail in FIG.
), it is constantly receiving a force in the direction of protrusion.

The force of this spring (21) causes the shoulder (1) of the stem (14) to
7) is in close contact with the packing (18), which causes the stem (1
The channel (15) and hole (16) of 4) are connected to the drug container (13).
The drugs inside are blocked.

The drug always reaches the housing chamber (20) under the pressure of the enclosed gas.

Next, the pressing body (23) (see FIG. 7) has the function of transmitting the force of the plunger (9b) to the stem (14), and also has the function of transmitting the force of the plunger (9b) to the stem (14).
) to the drug delivery tube (25).

The drug delivery tube (25) is then connected to the pair of nozzles (26) by a T-shaped flow distributor (26) mounted in the drug path.
27).

The functions of the optical detection device of the toilet seat sterilization device of the present invention shown in the above embodiments are as follows.

That is, the user touches the toilet seat cover (93) from the state shown in FIG.

As a result, the optical sensor (8) detects that the toilet seat lid (93) has been opened by light such as infrared rays passing through the light transmitting plate (4) of the cover (3).

This detection causes the control circuit (6) to control the solenoid device (9).
is driven by a timer circuit for a certain period of time (for example, 2 seconds).

In other words, the thin tip of the plunger (9b) is connected to the pressing body (2).
3) by pressing down on the stem (14) of the drug container (13).

As a result, the shoulder (1) of the stem (14) as shown in FIG.
7) is separated from the seal (18) and the drug is released from the housing chamber (20) through the hole (20) under gas pressure (e.g. 3 g/cm2).
16) and the flow path (I5) into the flow path (24) of the pressing body (23).

Additionally, the drug is delivered through the drug delivery tube (25) and the flow distributor (
26) to each of a pair of nozzles (27).

As a result, the medicine passes through the nozzle opening (5a) of the cover (3) from the nozzle hole (28), becomes spray A as shown in FIG. 8, and sterilizes the toilet seat (92).

Here, the spray A is preferably a spray with a flat elliptical cross section as shown in Fig. 9, and is inclined downward by approximately 1° from the horizontal plane, and the horizontal angle α widens to approximately 156 as shown in Fig. 8. .

(Effects of the Invention) The embodiments of the optical detection device of the toilet seat sterilization device of the present invention are as described above, and the effects thereof are listed below.

(1) Since the device of the present invention optically detects opening and closing of the toilet seat cover, reliable detection is possible.

(2) Since the device of the present invention optically detects opening and closing of the toilet seat cover, control becomes easy.
