In order to solve to invent the technical problem and realize goal of the invention, the invention adopts the following technical scheme:
A kind of Intelligent toilet cover and gasket assembly, including motor, upper cover and washer, the upper cover and washer pass through hinge and connect
It connects, the motor is for driving the upper cover to overturn；It is characterized by: being additionally provided with ultraviolet lamp, the ultraviolet lamp is arranged in institute
It states on upper interior surface and in face of the washer；The upper cover and washer are by sandwich layer, and are covered on the sandwich layer outer surface
Coating composition, and include nanometer anatase titania, irradiation of the titanium dioxide in ultraviolet lamp in the coating
It issues raw light-catalyzed reaction and generates hydroxyl radical free radical, to play the role of sterilization and eliminate stink.
Wherein, the Intelligent toilet cover and gasket assembly further include anion generator, speaker, WIFI transceiver module and control
Device processed；The controller is connect by PCB circuit board with motor, ultraviolet lamp and anion generator；The controller passes through function
Electric discharge road is connect with speaker；The controller is also connect with WIFI transceiver module, and the WIFI transceiver module passes through wireless routing
It is connect with intelligent mobile terminal.
Wherein, the intelligent mobile terminal is smart phone or PAD, and the intelligent mobile terminal sends a command to described
Controller, for controlling the motor, ultraviolet disinfecting, anion generator and speaker.
Compared with the immediate prior art, Intelligent toilet cover and gasket assembly of the present invention have below beneficial to effect
Fruit:
Intelligent toilet cover and gasket assembly of the invention can be controlled by intelligent mobile terminal, be sprayed without using sterilization
Agent or sanitary thin-film can be realized as eliminating peculiar smell and play bactericidal effect, guarantee clean hygiene.And it is sent out by anion
Raw device and speaker, are capable of providing music and the pure and fresh air rich in anion, and family can be used and obtain preferably experience.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of Intelligent toilet cover of the present invention and gasket assembly.
Fig. 2 is the functional block diagram of Intelligent toilet cover of the present invention and gasket assembly.
Specific embodiment
Intelligent toilet cover of the present invention and gasket assembly are further elaborated below with reference to specific embodiment,
To help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the invention, technical solution.
As shown in Figure 1, Intelligent toilet cover and gasket assembly of the invention, including upper cover 10 and washer 20, the upper cover 10
It is connected with washer 20 by hinge 30.Further include the motor for driving upper cover overturning, and be provided with ultraviolet lamp, bear from
Electronic generator, speaker, WIFI transceiver module and controller 40；The ultraviolet lamp is arranged on the upper interior surface and faces institute
State washer；The upper cover and washer are by sandwich layer, and are covered on the coating composition of the sandwich layer outer surface, and the covering
It include nanometer anatase titania in layer, light-catalyzed reaction occurs under the irradiation of ultraviolet lamp and generates hydroxyl for the titanium dioxide
Base free radical, to play the role of sterilization and eliminate stink.
As shown in Fig. 2, the controller is connect by PCB circuit board with motor, ultraviolet lamp and anion generator；It is described
Controller is connect by power amplifier with speaker；The controller is also connect with WIFI transceiver module, the WIFI transceiver module
It is connect by wireless routing with intelligent mobile terminal.It is net that Intelligent toilet cover and gasket assembly of the invention increases anion air
The functions such as change, music, act on toilet not only by anion generator and sterilamp and can sterilize and deodorization, but also
Elimination peculiar smell, the air of pure and fresh toilet can be played to clothing.Built-in WIFI transceiver module may be coupled to the nothing of household
Line router, so as to be connected to controller by the APP software of Intelligent mobile equipment such as smart phone or PAD, so as to
Realize the function of utilizing network-control.The intelligent mobile terminal sends a command to the controller by network, can be convenient
Ground controls the motor, ultraviolet disinfecting, anion generator and speaker.
In the present invention, the sandwich layer of the upper cover and washer defines the shape of the upper cover and washer, and the covering
The outer surface that finished product is constituted on the outer surface of sandwich layer is arranged in layer, and there is no particular restriction for the shape of the upper cover and washer, as long as
It can be matched with closestool, such as the washer can be oval structure for intermediate open O shape structure, the upper cover.It is described
Sandwich layer is preferably molded using the synthetic resin material of enhancing, and the synthetic resin for example can be polyolefin resin, such as
Common polyethylene, acrylic resin etc. are molded, and the coating is preferably that TPU resin (thermoplastic elastomer (TPE)) passes through note
It penetrates moulding process and is covered on the core layer surface.
In order to obtain wearability, resistance to soiling, product having enhanced antibacterial action TPU resin, TPU resin of the invention include with the following group
Point: the base polyurethane prepolymer for use as of 100 parts by weight, 2.0~3.2 parts by weight bisphenol-A sealing end dimethyl silicone polymer, 2.0~
The chain extender of the polyester diol of 10.0 parts by weight, 2.0~10.0 parts by weight, the modified nano-silica of 5.0~12.0 parts by weight
Change titanium (anatase titanium dioxide).Wherein, there is no particular restriction for the chain extender, such as optional common glycols, polynary
Alcohols or Diamines chain extender, specifically, in the present invention, the chain extender for example can choose 1,4-butanediol, second two
One or more of alcohol, propylene glycol, hexylene glycol, 1,6- hexylene glycol or hydroquinone two hydroxy ethyl ether.Wherein, the polyurethane
Performed polymer is prepared by the following method to obtain: by the benzene dimethylene diisocyanate (XDI) of 30~35 parts by weight, 45~50 weights
