Description

A deodorant toilet seat

Technical field:

The invention belongs to the technical field of sanitary ware and relates to an efficient and comfortable deodorizing toilet seat.

Background technique:

In daily life, the main way to deodorize the bathroom is the exhaust fan. After going to the toilet, the odor first diffuses in the bathroom, and then it can be exhausted by the exhaust fan after a period of time. This not only affects the air quality of the bathroom, but also affects the towels and bath towels in the bathroom. Therefore, the research and design of deodorant toilets have begun to attract people's attention. At present, the design ideas of deodorant toilets mainly include the following: one is the built-in exhaust device of the deodorant toilet seat, and the flushing port is used as the exhaust air. For toilets that have been installed and used without deodorizing functions, they can only be replaced by spending money, which is time-consuming, laborious, and expensive; After being adsorbed by activated carbon, it is discharged into the bathroom. Due to the high resistance of activated carbon, the adsorption capacity and adsorption efficiency are also limited, which affects the air suction volume, and the activated carbon needs to be replaced frequently, and the deodorization effect is not ideal; the other is to discharge the odor directly. , this way is the best, but the design of the exhaust system does not consider the changes in the air outlet area of the seat ring caused by going to the toilet, after going to the toilet, and people of different sizes, which will affect the collection efficiency of odor, and the air flow will It causes discomfort to the toilet user. Moreover, most of the existing deodorizing devices are controlled by touch pressure, and the exhaust air will stop when the person leaves, causing the exhaust gas and residual exhaust gas generated by the negative pressure in the center of the vortex to volatilize into the toilet space when flushing the toilet, causing pollute.

Invention content:

The purpose of the present invention is to overcome the shortcomings of the prior art, and seek to design and provide an efficient and comfortable deodorizing toilet seat, which can not only ensure the efficient deodorizing effect, but also give the toilet user a comfortable feeling.

In order to achieve the above object, the main structure of the present invention includes a toilet seat, a toilet seat, an air inlet, a hinge, a seat air pipe interface, a universal joint, a one-way valve, an axial flow fan, a wind pressure sensor converter, an extension Time display, fan switch, delay time adjustment button, control box, heating button, O-shaped silicone seal ring, toilet cover and air duct; The inner surface of the contact is covered with a carbon fiber electric heating film, which can be heated when going to the toilet in cold weather; the inner edge of the toilet seat is evenly spaced with multiple air inlets, and the bottom of the toilet seat is in contact with the toilet seat. An O-shaped silicone seal is made The O-shaped silicone sealing ring seals the gap between the toilet seat and the toilet seat body, so that when the axial flow fan sucks air, a slight negative pressure area is generated above the toilet seat to prevent the odor from spreading; there is a seat on one side of the hinge The air duct interface of the circle, the axial flow fan and the seat ring air duct interface are connected through the air duct, and the connection between the axial flow fan and the seat ring air duct interface is provided with a universal joint, so that the air duct does not affect the opening and closing of the toilet seat; The air duct between the axial flow fan and the toilet seat is equipped with a wind pressure sensing frequency converter, and the wind pressure sensing frequency converter automatically adjusts the speed of the axial flow fan according to the change of wind pressure caused by the area of the seat blocked by the toilet user. Air volume, maintain a stable micro-negative pressure value, prevent excessive negative pressure and excessive wind speed in the gap from causing discomfort to the toilet user, cover the toilet cover after going to the toilet, and use the gap between the toilet cover and the toilet seat to enter the air High-efficiency removal of residual odor can prevent the spread of odor to the greatest extent, reduce the exhaust air volume, and save electricity; the axial flow fan is directly connected to the exhaust channel of the bathroom, and the odor is directly discharged outside; the tail of the axial flow fan There is a one-way valve on the air duct to prevent the air flow back; the control box is fixedly connected with the axial flow fan, and the control box is equipped with a fan switch, a delay display, a delay time adjustment button and a seat heating button. Switch and adjust according to your own situation. The delay time adjustment button can collect and eliminate the residual odor. After going to the toilet, the delay running time of the fan can be adjusted through the delay time adjustment button. If the constipation does not come out for a long time, the time to go to the toilet Temporarily turn off the axial flow fan through the fan switch for a long time; the axial flow fan and the control box are installed on the left or right side of the toilet seat to suit the layout of the toilet.

Compared with the prior art, the present invention only needs to replace the toilet seat to realize functions such as deodorization, comfort and power saving, and will not bring about any change in operation and future troubles; its structure is simple and easy to operate , easy to produce, low in cost and environmentally friendly.
