Abstract

(1) The technical field to which the invention described in the claims belongs

Technique to put toilet cleaning liquid into water tank only a certain amount every time water is lowered

(2) Technical Problems to be Solved by the Invention

The commercially available toilet cleanser is wasted on the cleaning agent since it is continuously released into the water after being put into the water tank. For example, if you leave your home for a month and go on a trip, the cleanser must be completely unwound and replaced with a new one, which is no different than throwing a cleaning agent into the river. The object of the present invention is to inject only a certain amount of cleaning liquid each time water in the toilet water tank is crushed.

(3) The point of the solution of the invention

The water in the toilet water tank changes the mark level when you lower the water, and this change means energy. Accordingly, it is possible to operate the apparatus by changing the water level. In this apparatus, by using the difference in buoyancy of the two pistons according to the water level change, a certain amount of water is discharged from the toilet bowl Lt; RTI ID = 0.0 > of the < / RTI >

(4) Important Uses of the Invention

It can be installed in all household toilets, especially in public toilets where hygiene control is important and the users are constantly changing, even if the water is not frequent.

Description

Toilet flushing liquid injection device

It is a technology that automatically puts a certain amount of toilet cleanser into the market. As a commercially available toilet cleanser, it is solid form.

A certain amount of toilet cleanser is automatically injected using the change of the water level of the toilet water tank.

Fig. 1 shows the state of putting the toilet flushing liquid dosing device in the water tank. Use a heavy scaffold to prevent water from drifting and install a plastic case on top of it. In Figure 2, the case contains a rechargeable "wash tube" and the needle is plugged into the wash tube to feed the wash solution to the piston device. The dowels consist of a hollow glass buoyancy piston and a buoyancy piston, which protruded into a disk with a flat bottom (Fig. 2). The valve piston enters the 'cylinder 1' of the case and moves the buoyancy piston up and down in 'cylinder 2'. The figure is a real size, and 'L' is the distance that each piston moves.

The injection device can be roughly divided into 'case part' and 'piston device part'. The case part is shown in Fig. Figure 3 shows that the user drains the water in the toilet tank. The 'cylinder 1' of the injector and the 'upper box' containing the washing liquid and the tube have the same liquid level (the height of the water) and the tube is crushed by using the cleaning solution in the tube for a while. However, . By keeping the water level constant, the supply pressure of the washing liquid supplied through the 'injection needle' to the cylinder 1 is made constant (as the density of the washing liquid is close to the density of the water, accurate washing liquid can be supplied). The liquid in the cylinder 1 is a mixture of water and the washing liquid, and the concentration of the washing liquid (in the injection needle) under the rubber bore is not changed because the rubber ball at the bottom is blocking the hole of the 'washing liquid supplying needle'. A horizontal line was drawn and the cross-sectional shape of the corresponding position of the case was shown at the end thereof. A piston device is required to suck up the flushing fluid with cylinder 1 (because the injection needle is clogged with a rubber ball), as shown in Fig. The first one in Figure 4 shows the piston device installed in the case. The water tank is now filled with water, and the valve piston comes down and touches the rubber ball (pushing the rubber ball slightly). The disc portion of the valve piston (marked in black) has a circumferential spacing of 0.1 to 1.0 mm with cylinder 1, so that as the valve piston descends through cylinder 1, the already sucked wash fluid escapes into this gap. The upper end of the valve piston and the buoyant piston are spaced apart from each other by a greater distance of 0.5 to 2.0 mm from the cylinder in contact therewith, which is used to accelerate the movement of each piston.

The operation sequence is as follows. When the water in the toilet water tank is drained from the state shown in Figure 4 (water in the water tank is full), the valve piston moves upward (the buoyant piston descends) As the pressure is low, the cleaning fluid is sucked upwards. (There is a gap between the piston and the cylinder, so the cleaning fluid is sucked out by a volume that is smaller than the travel distance of the piston, but the amount is constant). When the movement speed of the valve piston drops, the rubber ball returns to its original position and the supply of the cleaning liquid is stopped. The water tank is soon filled with water. In the water, the weight of the valve piston is lower than the weight of the buoyancy piston (in this case, the buoyancy piston rises). In this process, the washing liquid, which has been sucked under the valve piston, 1, and mix it with the surrounding water. The valve piston pushes out the cleaning fluid and presses the rubber ball gently to prevent the cleaning fluid from leaking.

To repeat this process, the piston device shall satisfy the following conditions.

[Figure 5]

First, the valve piston in air is lighter than the buoyant piston.

Second, both the valve piston and the buoyant piston sink into the water.

Third, the valve piston in the water is heavier than the buoyancy piston.

The above relationship is expressed in terms of hydrodynamics as follows.

Mass of valve piston: m ₁

Mass of buoyancy piston: m ₂

Volume of valve piston: V ₁

Volume of buoyancy piston: V ₂

Density of water: ρ _u

, If the valve piston in the water is heavier than the buoyant piston

(m ₁ -ρ _w * V ₁ ) (m ₂ -ρ _w * V ₂ ). Rewrite

ρ _w * (V _{2 -} V ₁ ) (m _{1 -} m ₂ ), where V _{2 -} V ₁ .

Therefore, the above three operating conditions

Since the cleaning liquid injector proposed in the present invention has a structure in which two pistons are held in respective cylinders, it is not necessary to make the density of the buoyant pistons larger than the density of the water to sink into the water. therefore,

Thus, in Equation 2, if the volume V ₂ of the buoyant piston is increased and the density of the buoyant piston is made smaller than the density of water

, So that Equation 3 is satisfied.

Therefore, the conditions for this device are

Explaining

First, the buoyancy piston in the atmosphere is heavier than the valve piston.

Second, the buoyant piston floats in the water.

Third, the valve piston sinks in the water.

The piston is designed using these conditional expressions.

The washing liquid dispenser of the present invention automatically changes the level of the water tank to a predetermined amount to automatically remove the toilet cleaner even when the toilet bowl is not used for a long time, It saves resources by putting in a fixed amount.
