Example 1
The embodiment provides an inductive switch of a toilet seat ring, which comprises a first conducting piece 103 and a second conducting piece 104 which are arranged on the toilet seat ring 1, wherein the first conducting piece 103 and the second conducting piece 104 are arranged oppositely; the first conducting piece 103 or the second conducting piece 104 is elastically connected with the seat ring 2; the elastic connection part of the first conduction part 103 or the second conduction part 104 and the seat ring 2 is stressed or not through whether the seat ring 2 is pressed or not, and the first conduction part 103 and the second conduction part 104 are controlled to be contacted or not, so that the flushing of the toilet is controlled to be opened or closed. As shown in fig. 1-3.
The first conducting member 103 or the second conducting member 104 is elastically connected to the race 2, in other words, in practical applications, the first conducting member 103 may be elastically connected to the race 2, and the second conducting member 104 may be inelastically connected to the race 2; alternatively, the second conducting member 104 is elastically connected with the seat ring 2, and the first conducting member 103 is inelastically connected with the seat ring 2; the first and second conduction members 103 and 104 may be elastically connected to the race 2.
The first conduction piece 103 is in contact with the second conduction piece 104, and after conduction, the on or off of flushing of the toilet can be controlled in a mode of an electromagnetic valve or a control center of the toilet and the on or off time of the flushing of the toilet can be controlled in a mode of the electromagnetic valve or the control center of the toilet, so that the automatic flushing function of the toilet can be realized. When the inductive switch does not work, namely the first conducting piece 103 and the second conducting piece 104 are not in contact and are arranged oppositely and kept separated, the inductive switch of the embodiment does not need to consume electric energy, saves electricity, thereby reducing the overall power consumption of the toilet and prolonging the service life. When the power failure, rely on the battery power of squatting pan self, need to last the power supply and cause the great condition of power consumption to compare with electrostatic sensor normal during operation, the inductive switch of this embodiment saves the electric energy, can ensure that the squatting pan bath function lasts effectively for a long time.
The shape and structure of the first conducting piece 103 and the second conducting piece 104 are not limited, and in a non-use state, the first conducting piece 103 and the second conducting piece 104 are arranged oppositely, and a gap is kept between the first conducting piece 103 and the second conducting piece 104 without contact; once the elastic connection between the first conducting member 103 and the seat ring 2 is stressed, the first conducting member 103 moves towards the second conducting member 104, that is, the position where the first conducting member 103 and the second conducting member 104 are opposite to each other is located in the stress direction of the elastic connection between the first conducting member 103 and the seat ring 2; when the seat ring 2 is pressed, the first conduction piece 103 moves to enable the first conduction piece 103 and the second conduction piece 104 to be in contact with each other, and the flushing of the toilet bowl is controlled; when the seat ring 2 is not pressed, the acting force disappears, the elastic force rebounds due to the elastic connection relationship between the first conducting piece 103 and the seat ring 2, the first conducting piece 103 automatically resets, the first conducting piece 103 and the second conducting piece 104 are separated, a gap is still kept between the first conducting piece 103 and the second conducting piece 103, the first conducting piece 103 and the second conducting piece 104 are disconnected, the signal disappears, and the toilet does not flush; the length of the flushing time of the toilet is related to the length of the contact time between the first conduction member 103 and the second conduction member 104, and further related to the length of the force applied to the first conduction member 103, in other words, the length of the time that the seat ring 2 is pressed.
The first conducting piece 103 or the second conducting piece 104 is elastically connected with the seat ring 2, the specific elastic connection relationship is not limited by the description of the embodiment, and in practical application, after the seat ring 2 is subjected to seat pressure, the first conducting piece 103 and the second conducting piece 104 can be in contact with each other; when the seating pressure on the seat ring 2 disappears, the first conducting piece 103 or the second conducting piece 104 can be reset to a state that the first conducting piece 103 and the second conducting piece 104 keep a gap and are not in contact with each other by virtue of the elastic connection relation; thereby controlling the on or off of the flushing of the toilet. After the seat ring 2 is placed on the ceramic body 401, under the condition of no sitting pressure, the first conducting piece 103 and the second conducting piece 104 are arranged oppositely, the kept gap is enough to reach the non-conducting electric gap, the misoperation is prevented, and the condition that the toilet can still flush when no sitting pressure occurs is avoided.
It is conceivable that, in order to ensure the reliability of the above-mentioned inductive switch 1 to implement the flushing function, the number of the inductive switches 1 on the seat ring 2 may be set to more than one, and the inductive switches 1 may be set according to the needs in practical application, and may be uniformly distributed on the seat ring 2, or may be distributed according to the use habits of people and different seating positions; however, at least at the portion where the seat ring 2 is necessarily seated when seated, an inductive switch 1 is provided to ensure the effectiveness of the flushing function.
