Referring to Figure 1, the toilet tank 2 and the water used for flushing the toilet are combined. A water tank 4 for storing by force is shown. In addition, the aquarium also flushes the toilet A flash lever 6 that can be operated by hand to access the inside of the aquarium. A removable lid 8 is provided.

Each of the above elements may be of conventional construction.

Figure 1 is also. Also shown is a toilet deodorizing device, indicated schematically at 10. This deodorizer uses water A deodorizer installed in tank 4 and dispensed to remove or hide unpleasant odors. It accommodates.

As shown in detail in FIGS. 2 to 4, the deodorizing device 10 is.

The housing 12 is fixed to a pair of metal pieces 14 and 16 having an inverted U shape. . Each metal piece has a short leg (e.g., 1 in FIG. 4a) and, spaced from the short leg, connected to the short leg by a web (14-c) It has long legs (14b).

In particular, as shown in FIG. Used to removably attach 12. Metal piece 14.16 is metal. Because.

To sense the toilet flush in order to cause the deodorizer 10 to dispense deodorizer It is also used as an electrode.

In particular, as shown in FIGS. 3 and 4, the housing 12 has a cylindrical shape. A cylindrical side wall 18, a circular rear wall 20, and a substantially open deodorizer cartridge. It has a front wall that supports the ridge 22. The cartridge 22 also has a cylindrical shape. in the form of an annular flange in the center of the front wall with multiple radially extending ribs. Cartridge holder 2 attached to side wall 18 of the housing by 26 4 is supported. The front wall of the housing 12 is defined by the spaces 28 between the ribs 26. The area is essentially open.

There is an electric fan 30 inside the housing 12, and the fan 30 connects the space 28 and the car. A plurality of brakes provided within the housing are aligned with the cartridge holder ribs 24. It has an electric motor M that drives a board 32. When electric motor M is excited, Blade 32 forces air into space 28 and cartridge holder 24. The deodorizer is passed through the receiving cartridge 22, thereby removing the deodorizer from the cartridge. Dispense.

The housing 12 further includes a reservoir compartment 32 for holding a battery 34 and an electric motor. There is another compartment 36 for holding an electrical circuit 38 for controlling the motor M.

FIG. 5 shows an example of an electric circuit that can be used in the deodorizing device shown in FIGS. 1 to 4. shows. This electrical circuit responds to flushing the toilet with a manual switch MS, 2 An amplifier A that controls the motor 19 via two relays R1, R and a timer T. have.

Figure 5 shows the initial state of the electric circuit, particularly the contacts of relays R1 and R2 and timer T. state, e.g. the device is not yet attached to the aquarium 4 and therefore the two electrodes 1 manual switch in this initial state, indicating when 14°16 is not submerged in water. circuit is closed, but the two relays R, R2, timer T and motor M are energized. I can see that it hasn't woken up.

The device is attached to the aquarium 4, the aquarium is filled with water and the two electrodes 1.4.16 When submerged in water in the aquarium, relay R1 is energized and its contacts R1 are closed. At the same time, it can be seen that the contact R1 is opened. When contact R8 is closed, the reset occurs. When relay R1 is excited and contact R1 is opened, the circuit to timer T is cut off and the timer starts. remains unexcited.

Activation of relay R2 closes its contacts R2, thereby providing protection to the relay. Establish a maintenance circuit. Also, the contact R1 in the circuit to timer T is also closed. Since contact R1 is still open, the timer remains unenergized.

Activate the flush lever 6 to flush water from the water tank 4 into the toilet bowl 2 As a result, the water level WL (Fig. 2) in the water tank decreases, and the two electrodes 14 and 16 are exposed. put out This de-energizes relay R1, opens its contacts R, and Close contacts R and b. Even if contact R8, opens, it is not established by contact R2. Due to the holding circuit, relay R2 will not stop excitation, however, the contact When R1 closes, timer T is excited because contact R1m was closed first.

The excitation of timer T opens its contact T, which energizes relay R2. The stop, its contacts T, close, thereby energizing the motor M. Therefore, During this time interval when T is energized, motor M rotates the blades 32 of the fan. rotation to force air through space 28 and cartridge 22 and out of the cartridge. Dispense the deodorizer from the bottle.

After a predetermined time interval, e.g. 1 to 5 minutes, preferably about 2 minutes, timer T times out. , thereby opening contact T, thereby stopping the excitation of motor M. At the same time, contact T is closed, which causes relay R2 to switch to the next toilet flush. state for excitation by relay R1.

FIG. 6 shows another electrical circuit that can be used in the apparatus of FIGS. 1-4. No. The circuit of FIG. 6 is considerably simpler than the circuit of FIG. This circuit The time for refilling the tank 4 with water is used to excite the motor M that drives the blade 32. This is because that.

Thus, the circuit shown in FIG. 6 has an amplifier A controlling a single relay R. . This relay consists only of a pair of contacts R6 that control the excitation of the motor M. relay When R1 is not energized, contact R1 is normally in the closed position shown, so that There is one manual switch MS, which activates the motor M when the device is not installed in the aquarium. must be in the open position shown to prevent

When the device is installed in an aquarium and there is no water in the aquarium, electrodes 14.16 Submerged in water, closing manual switch MS immediately energizes relay R.

When relay R is energized, its contacts R1 open, thus.

Motor M remains unenergized. Now turn on the flush to flush the water. After actuating the lever 6, the water level in the tank 4 will drop below the electrode 14.16. Gari.

This stops the excitation of relay R. At the same time, contact R0 is closed normally. Return to position and excite motor M. When the aquarium begins to fill again, electrode 14. 16 is again immersed in water, thereby energizing relay R, opening its contacts, and causing this This stops the excitation of motor M.

In this way, the motor M of the circuit shown in FIG. 6 is excited, and the water level in the water tank 4 reaches two levels. begins when the water level falls below the level of electrode 14.16, and the water level submerges the two electrodes again. Dispense the deodorizer from the cartridge 24 until the end of the cycle. Figure 6 The simplified system shown in Figure 1 is thus first emptied and then refilled. A timer and a timer to energize the motor M to dispense the deodorizer determine the amount of time the aquarium takes to dispense the deodorizer. and use it.
