Abstract

The utility model relates to a toilet lid for removing odour and preventing infection for toilets. The utility model is composed of a photochemical oxidant generator, a human body toilet sensor, a replaceable isolating towel and an O-shaped soft seat cushion, wherein, the oxidant generator produces strong oxidant under the control of an electronic circuit to oxidate and decompose various odor components produced when a human body relieves nature. The utility model is provided with an electronic circuit module, a human body toilet sensor and the photochemical oxidant generator can be solely arranged on a bracket and arranged on an original O-shaped toilet lid of a user.

Description

Deodorizing and infection-preventing toilet cover

The utility model relates to a device for deodorizing a toilet bowl and preventing indirect contact and infection of skin diseases.

The toilet bowl is an indispensable device for modern toilets, and the toilets of residential buildings newly built in China from nine years to nine years and two years are all provided with the sitting toilets. The water sealing technology is adopted, so that the problem that stink is emitted from a pit bottom pipeline when the pit type toilet bowl is pedaled is solved, but the stink generated in the defecation process of a human body cannot be eliminated. But also can not eliminate the odor remained in the toilet bowl when the human body leaves the toilet bowl. The existing technology for eliminating the peculiar smell in the toilet is summarized into two types, one is toutilize special smell emitted by a certain chemical substance to interfere the peculiar smell, the other is to use a ventilation method, and the main peculiar smell in the toilet is the stink from urine and excrement. The two technologies can not eliminate the odor fundamentally, and on the other hand, the prior toilet seat cover can cause the cross infection of skin disease, gynecological disease and venereal disease when being used in public places (such as hotels and restaurants) where people flow.

The utility model aims at providing a can be at the device of defecation in-process automatic work production photochemistry oxidant ozone (O3), utilize ozone rapid oxidation decomposition foul smell and reach deodorant day, simultaneously the utility model discloses the cushion is sheathe in, has designed the isolation piece of cloth that can conveniently change, and this kind of isolation piece of cloth can be changed every day or along with using along with changing.

The specific technical scheme of the utility model is realized like this. A soft sleeve can be arranged outside an O-shaped plastic seat ring plate (or a hard bottom plate can be additionally arranged) of the prior closestool, and sponge is filled between the surface of the soft sleeve and the O-shaped seat ring plate. An electronic control module of the photochemical oxidant ozone generator is simultaneously installed in the soft sleeve, and the electronic module is encapsulated by insulating glue such as epoxy glue and the like. Meanwhile, a sensor switch is arranged in the sponge, so that the sponge can automatically work when a human body sits on the sponge. The photochemical oxidant generating device is arranged below the cushion cover and can not be contacted with or even seen by a human body, so that the photochemical oxidant generating device can not affect the appearance, but also can be directly contacted with odor, and the electronic module is provided bylow-voltage direct current (less than or equal to 12V). The power supply exchanger is led out by two flexible wires and placed outside the toilet bowl, and is generally inserted into an indoor power supply socket, a plurality of nylon buttons are arranged on an inner ring and an outer ring on the surface of the O-shaped cushion sleeve to stick and suck the isolation towel, the isolation towel can be stuck and torn slightly when in use, and a plurality of glue spots can be smeared on the isolation towel and directly stuck on the surface of the cushion. The isolation towel can be cloth or paper product.

The photochemical oxidant is used for deodorization, a power supply converter converts commercial power into low-voltage direct current, a digital integrated circuit oscillates to generate high-frequency pulse, the power is amplified to drive a pulse transformer, the generated high-frequency high-voltage ionizes air around an ozone generating tube to generate ozone (O3), the ozone is a very strong oxidant and can rapidly oxidize and decompose odor generated when a human body defecates, and the odor is changed into odorless and harmless substances through chemical action. Taking odor methyl mercaptan as an example, the reaction mechanism of ozone (O3) and the action thereof is as follows: ，，

it can be seen that the odor is finally converted into water, carbon dioxide and oxygen, and the reaction speed is extremely high.

The specific structure of the utility model is given by the following embodiments and the accompanying drawings, fig. 1 is a structure diagram, fig. 2 is an electrical control schematic diagram, fig. 1 (1) is an isolationtowel, (2) is a cushion face sleeve, (3) is a sponge cushion, (4) is a nylon button or adhesive sticker (5) is an O-shaped seat cover, (also can be an original O-shaped seat cover), (6) is a human body sensor, namely T in fig. 2, (7) is a photochemical oxidant generator, (8) is A, B2 in fig. 2 of an electronic circuit module, (9) a low-voltage power line is led out, and (10) is an external power converter, namely B1 in fig. 2. The soft cushion face sleeve (2) is made of high-grade waterproof artificial leather fabric, the electronic module (8) and the human body sensor (6) are embedded in the sponge in the face sleeve, and the sponge is sealed by the face sleeve (2). And the oxidant generator (7) is arranged below the O-shaped seat cover surface sleeve. The power converter (10) is sealed by the shell and is directly plugged into a power socket in a toilet. The electronic module, the human body sensor and the photochemical oxidant generator can also be made into a bracket to be directly arranged on the original O-shaped seat cover.
