1. Field of the Invention
The present invention relates to a sensor-activated toilet seat.
2. Description of the Prior Art
The conventional toilet seat includes a base body, a seat and a toilet lid. The seat and the toilet lid close the toilet when they are not used. When users need to use the toilet, they have to lift the toilet lid by hands, and then sit down on the seat. For gentlemen, they have to lift both the toilet lid and the seat to urinate. However, sometimes users' hands would touch fecal matters. If users use hands with fecal matters to put down the seat or the toilet lid on the toilet, the toilet would be stained with fecal matters. Besides, some gentlemen often urinate without lifting the seat. As a result, the seat and the inner side of the toilet lid would be stained with urine. And other users have to clean the surface of the seat and the inner side of the toilet before using. Otherwise, users' body would touch the fecal matters and feel uncomfortable. Moreover, uses have dangers of being exploded to those diseases infected by urine.
The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages.
The main object of the present invention is to provide a sensor-activated toilet seat which has an automatic function of lifting a toilet lid.
To achieve above, the sensor-activated toilet seat of the present invention includes a base body, a toilet lid, a seat, a controller, a first lid lifter, a second lid lifter, a first sensor, a second sensor and an electricity device.
The base body can be disposed on a toilet. The seat is located between the toilet and the toilet lid. The controller comprises a micro processor. The first lid lifter is used for making the toilet lid pivot with respect to the base body. The second lid lifter is used for making the seat pivot with respect to the base body. The first sensor is disposed on the toilet lid. The second sensor is disposed on a closing surface of the toilet lid.
When the first sensor detects movements of a human body, the micro processor starts up the second sensor and the first lid lifter so that the toilet lid pivots to a lifting position.
When the first sensor detects movements of the human body again, the micro processor starts up the second lid lifter so that the seat pivots to the lifting position as well.
When people is out of a detecting range of the second sensor, the micro processor starts up the first lid lifter and the second lifter with closing the second sensor so that the toilet lid and the seat would pivot back to a closing position.
The present invention provides a two-stage method of an auto-lifting toilet lid. Thus, users can choose to sit down on the toilet or lift the seat according to their needs. And after being used, the toilet lid and the seat can move back to the closing position automatically.

The toilet lid 20 includes a first end 21 and a second end 22. The first end can be pivotally disposed with the base body 10, and the second end 22 is on one end away from the base body 10. That is, the first end can be pivotally disposed on the shell 11 of the base body 10.
The seat 30, located between the toilet 1 and the toilet lid 20, can be pivotally disposed on the base body 10. That is, the seat 30 can be pivotally disposed on the shell 11 of the base body 10.
In the preferred embodiment of the present invention, as shown in
The second lid lifter 60 is disposed in the base body 10. To increase a perfection of the present invention, the second lid lifter 60 is disposed in the containing room 111. The second lid lifter 60 connects to the micro processor 41 electrically. The second lid lifter is used for making the seat 30 pivot with respect to the base body 10 so that the seat 30 can pivot between the lifting position and the closing position. In the preferred embodiment of the present invention, the second lid lifter 60 includes a second motor 61 and a second rotator 62. The second motor 61 connects to the micro processor 41. The micro processor 62 drives the second motor 61, and then the second motor 61 drives the second rotator 62. Thus, the second rotator 62 can rotate upward to lift or downward to close the seat 30.

The first adjusting unit is used for choosing one detecting range out of the detecting ranges of the first sensor. The first adjusting unit includes an auto-switching member 423, disposed in the detecting module 42 and connecting to the first adjusting member 421 electrically. When the toilet lid 20 pivots to the lifting position or the closing position, the auto-switching member 423 would make the first adjusting member 421 change the detecting range. In a preferred embodiment with more perfection, the first adjusting member 421 is assigned with a larger detecting range and a smaller detecting range. Therefore, when the toilet lid 20 pivots to the lifting position, the auto-switching member 423 would have the first adjusting member 421 switch the detecting range from the smaller detecting range to a larger one. When the toilet lid 20 pivots to the closing position, the auto-switching member 423 would have the first adjusting member 421 switch the detecting range from the larger detecting range to a smaller one.
The second adjusting unit, including an adjusting button 113, is used for choosing one detecting range out of the detecting ranges of the second sensor. The adjusting button 113 is disposed on the operation panel 112 with connecting to the second adjusting member 422. The adjusting button 113 offers a function of choosing a detecting range of the second sensor.

When people is out of the detecting range of the second sensor 80, the micro processor 41 starts up the first lid lifter 50 and the second lid lifter 60 with closing the second sensor 80, and the toilet lid 20 and the seat 30 would pivot to the closing position. At this moment, the auto-switching member 423 would switch the detecting range from the smaller one to the larger one. Thus, the first sensor and the second sensor are back to a condition that nobody uses. And users do not have to close the seat or the toilet lid by hands after using, so the seat and the toilet lid would not be stained by the urine or fecal matters on hands. Furthermore, the micro processor would close the second sensor to reach a goal of saving electricity as well.
By what is described above, when the toilet is positioned in a narrow lavatory, the second sensor would detect other objects even nobody is in the detecting range, causing a problem that the toilet lid or the seat could not pivot to the closing position. However, a combination of the second adjusting member and the adjusting button offers users to adjust the detecting range of the second sensor according to the size of the lavatory.
