Description

The present invention relates to a deodorizing and fragrance device of an automatic spraying type equipped with a chemical spraying mechanism for forcibly spraying a fragrance or a deodorant, and more particularly to a deodorizing and fragrance device effective for removing excretion odor in a flush toilet.

As a spraying method of the fragrance or deodorant used in the toilet, a normal spraying method, a manual spraying method, or an electric weak spraying method is generally used. The constant spraying method is by natural evaporation, and the manual spraying method is a spray method in which the spray can is operated by hand when necessary. The electric weak spraying method is a constant amount spraying method using an electric fan. The natural evaporation or electric weak spraying method has a small amount of chemical spraying and continues constantly, but has a problem in effect. The spray type has the advantage that it can be sprayed as needed, but there is a problem that it is impossible to avoid forgetting operation and bothering. In order to solve such a problem, an automatic spraying method that automatically sprays a large amount of fragrance or deodorant is considered. In this system, a spraying device provided with a drug spraying mechanism automatically sprays a drug at a preset timing. According to this method, the medicine is efficiently used at a preset timing. Moreover, it is freed from complicated operations. However, an important point in this method is the setting of the timing for spraying the fragrance or deodorant. That is, depending on the timing setting, the medicine is wasted or the deodorizing effect is insufficient. From this point of view, in the conventional automatic spraying, the spraying is basically performed during the period in which humans exist, the period during which the indoor lighting is lit, or the period spraying mechanism in which the human body detector senses the human body. This is described in Patent Document 1. Further, Patent Document 2 describes that a spraying mechanism is operated by using a human weighted operation. Further, Patent Document 3 describes that the water washing sound that operates after defecation is detected and the spray mechanism is operated.

However, these automatic spraying methods have the following inconveniences when considering removal of defecation odors in flush toilets.
It is unreasonable for the spraying mechanism to work while a person defecates in a flush toilet. In other words, since the defecation time in the flush toilet is usually several minutes, if the spraying mechanism is kept operating during that time, the medicine will be consumed more than necessary, and the medicine may be applied to the user. There is also. Also, it is not reasonable to spray at the start of use. This is because a defecation odor remains after use, and the next user will feel uncomfortable.
In addition, the method of operating the spraying mechanism by detecting the drainage sound may be caused by malfunction due to other sounds.

An object of the present invention is to provide an automatic spraying type deodorizing fragrance device that can effectively remove a defecation odor in a flush toilet with a small amount of medicine at a reliable timing.
In order to achieve the above object, a deodorizing fragrance device according to the present invention contains a fragrance or a deodorant and forcibly sprays the fragrance or the deodorant to the outside by a drug spraying mechanism. The apparatus includes a detection circuit for detecting a flush tank replenishment water flow after defecation and a drive circuit for operating the medicine spraying mechanism when a feed water flow to the flush tank of the flush toilet is detected.
The spraying of chemicals at the time when the feed water flow to the flush tank after use of the flush toilet is detected is the best spraying timing. This is because after the toilet is used, the deodorizing effect is high, the amount of medicine used can be saved, and the next user does not feel uncomfortable.
Also, the chemical spraying period takes about 70 seconds on average until the water supply to the washing tank is full and stops, and the chemical forcible spraying at this time has a sufficient deodorizing effect for the next user.
By adding a timer circuit for controlling the spraying time, the deodorizing effect can be adjusted, and the variation in the deodorizing effect due to the size of the toilet and the type of deodorizing agent can be adjusted.

The deodorizing fragrance apparatus according to the present invention contains a fragrance or a deodorant, and in the deodorizing fragrance apparatus forcibly spraying the fragrance or the deodorant to the outside by a drug spraying mechanism, the water supply water flow to the flush toilet is provided. Equipped with a detection circuit to detect and a drive circuit that activates the medicine spraying mechanism when the water supply flow to the tank of the flush toilet is detected, effectively removing the defecation odor in the flush toilet with a small amount of medicine Therefore, there is an effect that the amount of medicine used and power consumption can be greatly saved while maintaining high performance without causing discomfort to the next person's use.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of a deodorizing fragrance device showing an embodiment of the present invention. FIG. 2 is a configuration diagram of the deodorizing fragrance device. FIG. 3 is a circuit configuration diagram of the deodorizing fragrance device.
The deodorizing fragrance apparatus according to the present embodiment is an automatic deodorizing fragrance apparatus that is installed in a flush toilet room and automatically sprays a fragrance or a deodorant at a predetermined timing.
As shown in FIG. 2, the deodorizing fragrance device includes a case 1 placed on a toilet flush tank 4 in a toilet room.
In front of the case 1, a blowout port 2 and a suction port 3 are provided, and a water receiving port 5 for taking in water to the washing tank is provided.
In FIG. 1, the case 1 of the deodorizing apparatus is divided into upper and lower parts, a fan 8 constituting a medicine spraying mechanism is provided at the upper part of the case, and a medicine container 9, a printed circuit board 14, and a battery box 15 are provided at the lower part of the case. .
The fan 8 is driven by a drive motor (not shown) using a dry battery in the battery box 15 as a power source, thereby sucking air from the suction port and forcibly spraying the fragrance or deodorant into the toilet room from the blow-out port. The drive motor and the fan 8 constitute a medicine spraying mechanism, and a control circuit for controlling the operation of the drive motor is mounted on the printed circuit board 14.
The medicine container can be detached by separating the case 1 into an upper part and a lower part. A water flow detection unit 12 is provided at the lower part of the case 1 to detect the water flow of the washing tank water taken from the water receiving port 5 and generate the drive timing of the medicine spraying mechanism.

As shown in FIG. 3, the control circuit for controlling the operation of the fan drive motor comprises a water flow sensor 17, an energization control circuit 16 for controlling on / off of the fan drive motor 18 by the output of the water flow sensor 17, and a power supply unit 19 for driving the fan motor. Has been.
As described above, the water flow detection unit 12 is attached to the lower part of the case 1, and when water supply to the washing tank is started at the water receiving port on the upper part of the case 1, the water flow passes through the path in the apparatus, and the water flow detection unit 12 After being led to, it is discharged from the drain outlet at the bottom and falls into the washing tank. When the water flow detection unit detects the supply of water to the washing tank, the water flow detection unit gives an ON signal to the energization control circuit constituting the drive circuit of the medicine spraying mechanism. As a result, the fan drive motor 18 operates while water supply to the flush tank continues, and a necessary and sufficient aroma / deodorant effect is obtained. A plurality of slit-like air inlets are opened on the upper back surface of the case 1, and a plurality of slit-like air outlets are opened on the upper front surface of the case 1. In the upper space of the case 1, an air flow path portion that connects the air inlet and the air outlet is formed. In addition, a container 9 in which a liquid fragrance or a liquid deodorant is enclosed is disposed under the case 1. From the upper end opening 10 of the container 9, a water absorbing material 11 such as a sponge immersed in the container 9 protrudes outward as an evaporating and diverging part of the liquid fragrance or deodorant, and the air above the case 1 It extends to the channel part.

Next, operation | movement of the deodorizing apparatus concerning this embodiment is demonstrated.
When defecation is completed in the flush toilet and drainage is performed, water supply to the flush tank is started in preparation for the next drainage. This water supply is led to the water receiving port of the deodorizing fragrance device of the present invention installed between the water supply faucet and the water washing tank, detected by the water flow detection unit, and while the water supply to the water washing tank continues, the fan drive motor and The fan operates.
Thereby, a fragrance | flavor or a deodorizer is forcedly sprayed in a toilet room.
That is, after the defecation, the medicine is sprayed for a predetermined time simultaneously with the start of the drainage only when the drainage is performed. As a result, the defecation odor accumulated in the room is removed.
According to this, since spraying is performed after defecation in the flush toilet, the defecation odor trapped in the room is effectively removed. Moreover, since there is no reoccurrence of the defecation odor after spraying, there is no odor during the next use, and the next user will not have any discomfort. That is, despite the short spraying, deodorization is performed effectively and no residual odor is produced. Needless to say, the consumption of the drug is significantly reduced compared with the case of continuing spraying during use.
In addition, if a timer circuit is added to the control circuit, the electric fan operation time from the start of water supply can be set regardless of the time required for water supply in the flush tank, and the deodorization time after defecation can be adjusted arbitrarily, and Variations in the time required for water supply to the washing tank due to differences can be corrected.
