Dosing device

Abstract

The invention provides a dosing device which is placed in a filter element and used for disinfecting water filtered by the filter element, and the dosing device comprises a shell and a tablet cylinder; the shell comprises a water inlet, a water outlet, a containing cavity and a water outlet control assembly, and the water outlet control assembly is used for controlling the water outlet to be opened when the water flow direction in the filter element is consistent with the water flow direction of the containing cavity and controlling the water outlet to be closed when a water flow in the filterelement is static. The dosing device w realizes automatic opening and closing according to flowing or standing of water in the filter element, the water outlet is opened when the water in the filterelement flows from the water inlet direction to the water outlet direction, and the water outlet is closed when the water in the filter element is static. And meanwhile, the water outlet control assembly can realize rigid sealing of the water outlet when the water in the filter element is static, so that the dosing device can work in an acid environment for a long time. The tablet cylinder is placed in the containing cavity, a preset number of tablets are placed in the tablet cylinder, and when the water enters the water inlet, the water is contacted with the tablets and then flows out of thewater outlet.

Description

technical field [0001] The invention relates to a liquid filtration and disinfection device, in particular to a drug dispenser. Background technique [0002] A drug dispenser is a common device used to purify pool water. A common drug dispenser includes a closed container in which tablets capable of purifying water are housed. In order to prevent the drug dispenser from sinking into the bottom of the water after being put into the pool, foam is generally placed in the container of the drug dispenser to increase the buoyancy of the drug dispenser, so that the drug dispenser placed in the pool can float on the water surface, which is convenient for users to observe And change the tablet in the container at any time. [0003] However, most of the current drug dispensers only contact the tablets with the water in contact with the drug dispenser, and the water in other areas needs to be circulated through all the water to achieve the purpose of disinfection. In this way, there ...

Problems solved by technology

[0003] However, most of the current drug dispensers only touch the tablets when they are in contact with the drug dispenser, and the water in other areas needs to be circulated through all the water to achieve the purpose of disinfection

In this way, there will be problems such as uneven delivery of tablets and low disinfection efficiency.

At the same time, some of the dosing devices on the market do not have a switch function, so that the opening and closing of the dosing device cannot be controlled, resulting in the dosing device being in use for a long time. Another part of the dosing device with a switch function also has a defect, that is, it needs to be opened manually. Switch to control the start and stop of the doser, making it not convenient to use
