Limited drainage controller with liquid arranged in middle

Abstract

A limited drainage controller with liquid arranged in the middle comprises a liquid storage tank, and the liquid storage tank is connected with a dosage tank. A communicating opening is formed betweenthe liquid storage tank and the dosage tank. A first control valve is mounted in the communicating opening, and a drainage opening is formed below the dosage tank. A second control valve is arrangedin the drainage opening, and when the second control valve is closed, the first control valve is opened, the liquid storage tank communicates with the dosage tank, and liquid in the liquid storage tank flows into the dosage tank. When the second control valve is opened, the first control valve is closed, liquid in the dosage tank is drained out of the drainage opening. The first control valve andthe second control valve form a linkage valve, the linkage valve comprises a pull rod, and a top valve block is arranged on the upper portion of the pull rod. The top valve block is in contact with the bottom of the liquid storage tank, and a bottom valve block is arranged on the lower portion of the pull rod. The bottom valve block is in contact with the lower face of the bottom of the dosage tank, and toilet cleaner is placed in the liquid storage tank. The storage tank communicates with the dosage tank, and the dosage tank determines the volume according to the liquid dosage requirement. The drained liquid reaches the use effect and is not wasted. By means of valve control, high reliability is achieved, and the service life is long.

Description

[0001] This patent application is a divisional application of the case of "Patent name: liquid central-mounted limited discharge controller, application number: 2016101750822, and application date is March 25, 2016". technical field [0002] The invention relates to a liquid-mounted limited discharge controller, which is mainly used for the packaging of toilet cleaning liquid to limit the discharge flow, and can also be used on taps for each hand-washing discharge. Background technique [0003] Existing lavatory cleaners are divided into bottled lavatory cleaners and tube-packed lavatory cleaners. Bottled lavatory cleaners are liquids that can be poured directly into the toilet bowl without flow restrictions. The waste of toilet liquid, when pouring less, can not achieve the effect of cleaning the toilet. The toilet cleaner in the tube is a paste, which needs to be squeezed out and applied on the inner wall of the toilet. When the paste toilet cleaner on the toilet is used, ...

[0003] Existing lavatory cleaners are divided into bottled lavatory cleaners and tube-packed lavatory cleaners. Bottled lavatory cleaners are liquids that can be poured directly into the toilet bowl without flow restrictions. The waste of toilet liquid, when pouring less, can not achieve the effect of cleaning the toilet. The toilet cleaner in the tube is a paste, which needs to be squeezed out and applied on the inner wall of the toilet. When the paste toilet cleaner on the toilet is used, due to the washing of the toilet wall by the water flow, the amount of the paste toilet cleaner on the inner wall of the toilet is increased at first, and then less, which will cause uneven effect on the toilet

In addition, on faucets in public toilets and other places, in order to achieve the purpose of saving water, in the prior art, spring switches or sensor switches are installed on the faucets. The spring switches will reduce the performance of the springs and affect the control effect as the time of use increases. When the sensor switch is in use, it is easy to fail, which will affect the water saving effect
