When a closet seat cover 93 is opened by a user, then by the light sensor 8, it is detected that the closet seat cover 93 is opened by the light of the infrared ray or the like passing the light transmitting plate 4 of the cover 3, and by a control circuit 6, a solenoid device 9 is driven for a fixed time, and by a plunger 9b, the stem 14 of a disinfectant vessel 13 is pushed down via a pressing body 23. Disinfectant comes to a pair of respective nozzles 27 through a disinfectant feeding tube 25 and a flow distributing device 26 and is turned into spray through the nozzle opening of the cover 3 from nozzle holes 28, and germs are sufficiently removed from the whole closet seat 92.

Description

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

(Means for Solving the Problems) In order to achieve the above objects, the present invention includes: 1. A device body attached to the rear part of the toilet bowl; and a device installed on both sides of the device body to spray a medicine onto the toilet seat. The present invention proposes a nozzle device for a toilet seat sterilization device consisting of a pair of nozzles.

(Function) (1) Since the device of the present invention has a pair of nozzles, it is possible to reliably spray the medicine onto the toilet seat, and as a result, the entire surface of the toilet seat can be thoroughly sterilized.

(2) Since the device of the present invention has a pair of nozzles particularly arranged at the rear of the toilet bowl, it does not cause any problems when using the toilet bowl.

(Example) The nozzle device of the toilet seat sterilization device of the present invention will be described below according to an 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 body (1) is attached to a bottom plate (2) made of polycarbonate resin or the like and made of ABS.
It consists of a cover (3) made of 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, 3 J/cm2) 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 (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 a warning is issued by lighting up the light emitting diode D, and it is also possible to switch to a 100V commercial power source.

The control circuit (6) includes the light source (7) and the optical 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 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

4) The channel (■5) and hole (16) are the drug container (13)
are blocked from internal drugs.

The medicine always reaches the housing chamber (20) due to the pressure of the enclosed waste.

Next, the pressing body (23) (see FIG. 7) has a flow path (24) of the stem (14) in addition to the v1 function of transmitting the force of the plunger (9b) to the stem (14).
15) 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 nozzle device of the toilet seat sterilization 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 1f (93) is 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 gasket (18) and the drug passes from the housing chamber (2o) through the hole (16) and the flow path (15) under gas pressure (for example, 3 Kg/cn+") to the pressing body (23).
into the flow path (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).

Here, spray A is a spray with a flat elliptical cross section as shown in Fig. 9, and is tilted downward by approximately 1°0 from the horizontal plane, with the left and right angle α expanding to approximately 15° as shown in Fig. 8. desirable.

(Effects of the Invention) The embodiments of the nozzle 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 has a pair of nozzles, it is possible to reliably spray the medicine onto the toilet seat, and as a result, the entire surface of the toilet seat can be thoroughly sterilized.

(2) Since the device of the present invention has a pair of nozzles particularly arranged at the rear of the toilet bowl, it does not cause any problems when using the toilet bowl.
