Description
Technical Field
The invention relates to a toilet cover plate, in particular to an automatic closing device of the toilet cover plate.
Background
The existing toilet cover plate has no automatic closing function, and a user needs to use hands to close the cover plate after using a toilet, so that the use of the user is inconvenient.
Disclosure of Invention
The invention aims to provide an automatic closing device for a toilet cover plate, which does not need to be closed by a user after the toilet is used.
In order to implement the purposes, the invention adopts the following technical scheme:
the automatic closing device of the toilet cover plate comprises a fixed sleeve, a linkage head, a rotating head, a spring, a clutch, a driving executing piece and a control circuit;
the linkage head is arranged in the fixed sleeve and is in running fit with the fixed sleeve, one end of the linkage head is connected with an upper cover of an external toilet, the linkage head is tightly matched with one end of the rotating head through a claw with a spiral end face which is correspondingly arranged on the linkage head and the rotating head, the rotating head is arranged in the fixed sleeve, when the linkage head rotates, the rotating head axially moves in the fixed sleeve, the other end of the rotating head is abutted against one end of a spring, the other end of the spring is abutted against the left half body of the clutch, the left half body of the clutch is in meshed connection with the right half body of the clutch through a claw which is correspondingly arranged, the other end of the linkage head is connected with the left half body of the clutch, when the linkage head rotates, the clutch is also arranged at one end of the fixed sleeve, the driving executing piece is positioned at one side of the right half body of the clutch, and the driving executing piece is electrically connected with the control circuit; the control circuit comprises a PCB and an inductor used when a human body leaves, the inductor is arranged on the PCB and is electrically connected with the PCB, and the PCB is arranged in the fixing sleeve.
Further:
the sensor is an infrared sensor.
The driving executing piece can be an electromagnet, a miniature motor and the like.
Compared with the prior art, the invention has the following beneficial effects:
when in use, the invention is arranged in the pivot tube which is rotatably connected with the seat ring by the upper cover at the rear part of the toilet cover plate (the control circuit can be arranged outside the pivot tube). The working principle of the invention is as follows: 1) The energy storage process comprises the following steps: after the cover plate is opened by a certain angle, the upper cover starts to drive the linkage head and the clutch a to rotate together when the cover plate is continuously opened, the rotating head compresses the spring to perform energy storage action, and when the cover plate is opened to a certain angle (for example, 105 degrees is set), the claw on the left half body of the clutch is clamped on the claw on the right half body of the clutch, so that the linkage head cannot reset because the spring pushes the rotating head. Ensuring that the cover plate is not automatically closed; 2) Energy release: after the toilet is finished, a person leaves the toilet, an inductor (such as an infrared inductor) on the PCB senses that no obstacle exists in front of the toilet, and then the control circuit enables the electromagnet to start working, and the electromagnet pulls the right half of the clutch, so that the right half of the clutch is separated from the left half of the clutch. Because the spring is always in a compressed state before, the first clutch is separated, the spring pushes the rotating head to reset, and the rotating head drives the linkage head to rotate. The linkage head drives the upper cover to rotate, so that the opening angle of the cover plate is smaller than a certain angle (for example, 90 degrees is set), and the upper cover performs automatic closing action due to the gravity.
