[0004] In order to solve the above technical problems, the present invention provides an automatic auxiliary device for flushing a toilet, including a horizontally arranged body, a servo motor, a controller and a power supply are arranged in the body, the servo motor body is installed in the body and is connected to the power supply through the controller, the output shaft of the servo motor runs forward and backward, and a first gear and a second gear are coaxially connected in series on the output shaft of the servo motor, a first rack arranged horizontally and meshing with the first gear is provided beside the first gear, one end of the first rack in the length direction is flexibly connected with a horizontal axis, an end of the horizontal axis away from the first rack is provided with a vertically extending downward vertical axis, a first push rod extending along the left and right direction toward the side close to the servo motor is provided at the lower end of the vertical axis, a second rack arranged vertically and meshing with the second gear is provided beside the second gear, a vertically arranged second push rod is connected to the upper side of the second rack, the upper side of the second push rod protrudes out of the body, a vertically arranged third push rod is flexibly connected to the lower side of the second rack, the lower side of the third push rod protrudes out of the body, a human body sensor arranged horizontally and forward is provided on the body, and the human body sensor is connected to the controller.

[0005] For the purpose of simple explanation, the automatic auxiliary device for flushing toilet described in the present invention is referred to as the device below.

[0006] How to use this device:

[0007] For a water tank with a top-press flush switch, the horizontal axis, the vertical axis connected to the horizontal axis, and the first push rod are removed from the end of the first rack, and then the body is installed on the top of the water tank so that the lower side of the third push rod is directly opposite to the flush switch of the original water tank. In actual use, when the human body sensor first captures the human body, and after a certain period of time, the human body is separated from the human body sensor, the controller controls the servo motor to rotate, and the second gear on the output shaft of the servo motor drives the second rack downward. The third push rod is driven by the second rack to trigger the flush switch. After a short delay, the controller controls the servo motor to reverse and reset the third push rod. The delay time is proportional to the flush volume of the toilet. The human body sensor starts counting from the time when the human body is captured until the human body is separated from the human body sensor again. The interval time is the toilet time. According to the length of the toilet time, it is judged whether it is urination / defecation, thereby controlling the delay time after the servo motor triggers the flush switch, that is, controlling the flush volume. When the circuit is interrupted or the control system fails, the second push rod is pressed downward, and the second push rod pushes the third push rod downward through the second rack, triggering the flush switch to complete the flushing operation. After flushing, the second push rod is pulled upward to reset the third push rod upward.

[0008] For the water tank with the side-press flush switch, the third push rod is removed from the lower side of the second rack, and then the machine body is installed on the top of the water tank so that the end of the first push rod is against the flush switch on the side of the water tank. In actual use, when the human body sensor first captures the human body, and after a certain period of time, the human body is separated from the human body sensor, the controller controls the servo motor to rotate, and the first gear on the output shaft of the servo motor drives the first rack to move in the left-right direction away from the vertical axis. The first push rod triggers the flush switch driven by the vertical axis. After a short delay, the controller controls the servo motor to reverse and reset the first push rod. The delay time is proportional to the flush volume of the toilet. The human body sensor starts counting from the time when the human body is captured until the human body is separated from the human body sensor again. The interval time is the toilet time. According to the length of the toilet time, it is judged whether it is urination / defecation, thereby controlling the delay time after the servo motor triggers the flush switch, that is, controlling the flush volume. When the circuit is interrupted or the control system fails, the second push rod is pressed downward, and the second push rod drives the second gear to rotate through the second rack. The first gear coaxial with the second gear drives the first rack to move to the side away from the vertical axis. The first push rod is driven by the vertical axis to trigger the flush switch to complete the flushing operation. After flushing, the second push rod is pulled upward to reset the first push rod.

[0009] Advantages of this device: This device is based on the existing traditional toilet and is installed on the existing toilet. It detects the toilet time through a human body sensor, then provides the corresponding flushing volume according to the toilet time, and automatically performs the flushing operation. In addition, according to the two flushing switch arrangements of the existing toilet water tank, a dual-purpose control component is provided, which can be disassembled and assembled as needed. In addition, when the circuit is interrupted or the control system fails, the flushing effect can also be achieved by manually controlling the second push rod without affecting the flushing of the toilet.

[0010] In order to achieve better use effect of this device, the preferred scheme is as follows:

[0011] Preferably, an external foot switch assembly is provided on the side of the machine body, a signal transmitter is provided inside the foot switch assembly, and a signal receiver matching the signal transmitter is provided inside the machine body.

[0012] The addition of the foot switch can facilitate the user to manually control the flushing operation when the toilet needs to flush outside the automatic flushing trigger conditions. This can make the toilet function more complete and more in line with people's usage habits and requirements.

[0013] Preferably, a horizontally arranged outer frame is provided on the outer circumferential side of the machine body, the machine body is connected to the outer frame via a plurality of connecting columns, and the end of the transverse axis away from the first rack and the upper end of the second push rod both pass through the outer frame.

[0014] The outer frame structure matches the upper part of the water tank. During installation, first remove the upper cover of the water tank, and then install the outer frame directly on the upper side of the water tank. According to the layout of the flush switch of the water tank itself, disassemble and assemble the relevant components, and make them cooperate with the original flushing mechanism. Finally, the water tank cover is set on the upper side of the outer frame. Such a structure makes the body position as the preferred one. The human body sensor is set on the inner side of the body, and its probe extends to the front side of the outer frame.

[0015] The human body sensor adopts an internal layout and does not need to be extended outside the water tank, which makes the overall appearance more beautiful.

[0016] Preferably, a horizontally arranged pancake-shaped control head is provided at the upper end of the second push rod.

[0017] The round pancake-shaped control head is more convenient for manual operation and more beautiful.

[0018] Preferably, the human body sensor is equipped with a voice receiving control module, and the voice receiving control module is connected to the controller.

[0019] Through the voice receiving control module, you can control the flushing by voice commands, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

In actual use, when the human body sensor 7 first captures the human body, and after a certain period of time, the human body is separated from the front of the human body sensor 7, the controller controls the servo motor 2 to rotate, and the first gear 21 on the output shaft of the servo motor 2 drives the first rack 4 to move in the left-right direction away from the side of the vertical axis 42. The first push rod 43 is driven by the vertical axis 42 to trigger the flush switch 62. After a short delay, the controller controls the servo motor 2 to reverse and reset the first push rod 43. The delay time is proportional to the flushing volume of the toilet. The human body sensor 7 starts counting from the capture of the human body until the human body is separated from the front of the human body sensor 7. The interval time is the toilet time. According to the length of the toilet time, it is judged whether it is urination / defecation, so as to control the delay time after the servo motor 2 triggers the flush switch 62, that is, the flushing volume is controlled. When the circuit is interrupted or the control system fails, the second push rod 31 is pressed downward, and the second push rod 31 drives the second gear 22 to rotate through the second rack 3. The first gear 21 coaxial with the second gear 22 drives the first rack 4 to move to the side away from the vertical axis 42. The first push rod 43 is driven by the vertical axis 42 to trigger the flush switch 62 to complete the flushing operation.
