In other words, the stem 14 of a disinfectant vessel 13 is pushed down by the slender tip of a plunger 9b via a pressing body 23. Disinfectant comes to a pair of respective nozzles 27 through a a disinfectant feeding tube 25 and a flow distributing device 26 and is turned into spray through the nozzle opening 5a of the cover 3 from nozzle holes 28, and germs are removed from a closet seat 92.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a spray control circuit 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) An object of the present invention is to provide a spray control circuit for a toilet seat sterilization device that solves the above-mentioned conventional problems and enables reliable sterilization.

(Means for Solving the Problems) In order to achieve the above objects, the present invention includes: 1. an optical detection means for detecting that the toilet seat lid is opened;
The present invention proposes a spray control circuit for a toilet seat sterilization device that includes a timer circuit that sprays a chemical for a certain period of time based on detection by the optical detection means.

(Function) (1) Since the circuit of the present invention specifically performs detection using an optical detection means, reliable detection is performed.

(2) Since the circuit of the present invention particularly includes a timer circuit, the chemical is reliably sprayed for a certain period of time and sterilization is performed.

(Example) The spray control circuit of the toilet seat sterilization device of the present invention will be described below according to an example shown in the drawings.

1 to 4 show a toilet seat sterilization device using the circuit of the present invention, and the device has a device main 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).
will be 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 source (7) that emits infrared rays and the like and a light sensor (8) that receives 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, 3g/cff12) 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 (10) or a commercial power source.

The battery (lO) 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 a warning is issued by lighting up the light emitting diode D, and it is also possible to switch to a commercial power source of 100 cm.

The control circuit (6) includes the light source (7) and the optical sensor (8).
When it is detected that the toilet seat fi (93) has been 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 has a tapered tip.

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).
It is blocked from internal drugs.

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 spray control circuit of the toilet seat sterilizing device of the present invention shown in the above embodiments are as follows.

That is, the user opens 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, as shown in Fig. 7, the shoulder (1) of the stem (T1)
7) is separated from the packing (18), and the drug passes from the housing chamber (2o) through the hole (I6) and the flow path (15) under the pressure of the residue (for example, 3 K3/cm") to the flow path of the pressing body (23). (24).

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).

As shown in FIG. 9, the spray A is a spray with a flat circular cross section, extending approximately l downward from the horizontal plane.

° In the tilted state, the left and right angle α is approximately 15 as shown in Figure 8.
It is desirable that it spreads to 100°.

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

(1) Since the circuit of the present invention specifically performs detection using optical detection means, reliable detection is performed.

(2) Since the circuit of the present invention particularly includes a timer circuit, the chemical is reliably sprayed for a certain period of time and sterilization is performed.
