Embodiment 1

[0029] In this embodiment, a chlorine dioxide slow-release gel device for toilets, a chlorine dioxide slow-release gel device for toilets, includes a housing 1 and a container 2; the housing 1 is provided with a fixing device 5, and the housing 1 Air holes 4 are distributed on the surface; the container 2 is located in the shell 1 and is equipped with chlorine dioxide slow-release gel;

[0030] like figure 1 , the shell 1 includes a box body and a cover body 3, the box body is provided with a cavity inside, and the cover body 3 and the box body can be opened and closed by locks, buckles, knobs or threads. When the cover body 3 is opened, the container 2 can be loaded into or replaced in the cavity, and when closed, the two are sealed. In practical application, the cover body 3 can be hinged on one side of the box body, and when the cover body 3 is closed, it can be locked by a lock, buckle or knob; or the box body is provided with external threads, and the cover body 3 is pro...

Embodiment 2

[0035] The difference between this embodiment and Example 1 is that the chlorine dioxide slow-release gel in the device is prepared in the following way:

[0036] Put 1kg of polyvinyl alcohol particles into a slow kneader, directly add 3L of sodium chlorite aqueous solution with a concentration of 1.3mg / L, and disperse evenly for 20min to obtain chlorine dioxide precursor hydrogel; then take 50g of In the container 2 of the slow-release gel plastic device; dissolve oxalic acid in water (0.8ppm), and pack it into a small package of 20g; directly add 1 pack of oxalic acid aqueous solution into the container 2 of the device, shake evenly for 1min, and the product is made Slow-release chlorine dioxide hydrogel.

[0037] The air purification and bactericidal effects of the chlorine dioxide gel device prepared in this example were detected, and the removal rate to ammonia was 91%, the removal rate to formaldehyde was 85%, and the bactericidal rate to Escherichia coli was 100%. , ha...

Embodiment 3

[0039] The difference between this embodiment and Embodiment 1 is that a suction cup device is installed on the side of the casing 1, and the device is fixed on the bathroom mirror surface by adsorption during use. The chlorine dioxide sustained-release gel in the device is prepared by:

[0040] Put 1 kg of polyethylene glycol particles into a slow kneader, directly add 4L potassium chlorite aqueous solution, the concentration of which is 0.8 mg / L, and disperse evenly for 20 minutes to obtain chlorine dioxide precursor hydrogel; then take 50 g and distribute it in In the container 2 of the slow-release gel plastic device; dissolve citric acid in water (1.2ppm), and pack it into small packages of 20g; directly add 1 pack of citric acid aqueous solution into the container 2 of the device, shake evenly for 1min, and prepare into a slow-release chlorine dioxide hydrogel.

[0041] The air purification and bactericidal effects of the chlorine dioxide gel device prepared in this exa...

Abstract

The invention discloses a chlorine dioxide slow-release gel device for a toilet and a sterilization toilet lid of the chlorine dioxide slow-release gel device. The slow-release gel device comprises a shell and a container, the shell is provided with a fixing device, and air holes are distributed in the surface of the shell; the container is positioned in the shell and is filled with chlorine dioxide slow-release gel; the chlorine dioxide slow-release gel is prepared by mixing and reacting precursor gel and a sensitizing agent in the container according to the mass ratio of 5: 2 for 1-3 minutes; the concentration of the sensitizing agent is 0.8-2.0 ppm, and the precursor gel is formed by adding 2-4L of a chlorine dioxide precursor solution with the concentration of 0.8-5.1 mg / L into each kg of hydrophilic resin, uniformly performing stirring for 10-30 minutes and performing kneading. The slow-release gel device is arranged on the inner side of the cover plate of the sterilization closestool cover, sterilization, disinfection and deodorization are carried out on a closestool and a toilet, and the sterilization closestool cover has the advantages of being simple in structure, good in sterilization and disinfection effect, safe, stable, long in continuity, free of power consumption and the like.

Description

technical field [0001] The invention belongs to the field of bathrooms, and in particular relates to a chlorine dioxide slow-release gel device for toilets and a sterilizing toilet cover thereof. Background technique [0002] With the improvement of living standards and the enhancement of environmental protection awareness, people pay more and more attention to the sterilization and deodorization in home life. The bathroom is an indispensable facility for family life. Its internal hygiene is mainly through spraying various disinfectants or other toilets However, because there are dead corners inside the bathroom, the use of disinfectant and other disinfection methods often miss the dead corners, resulting in incomplete disinfection. Over time, bacteria in the dead corners continue to breed and reproduce, making the bathroom smell bad, and some bacterial spores It will disperse in the bathroom and bring harm to users. In the prior art, active carbon or ultraviolet lamps are ...
