[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-2 The embodiment of the present invention discloses a toilet auxiliary flushing device, which is used to press a flushing button in a toilet water tank, comprising:

[0026] case;

[0027] The driving part includes a driving mechanism 1 and a push rod 3. The driving mechanism 1 is arranged in the housing. The push rod 3 is connected to one end of the driving mechanism 1 close to the flush button. The end of the push rod 3 away from the driving mechanism 1 can extend out of the housing. The driving mechanism 1 controls the push rod 3 to approach or move away from the flush button.

[0028] The control unit includes a sensor 2 and a control system. The sensor 2 is electrically connected to the control system. The control system is electrically connected to the driving mechanism. The control system controls the driving mechanism to drive the push rod 3.

[0029] In some embodiments, the sensor 2 is fixed on the housing.

[0030] In some embodiments, the sensor 2 is fixed to a fixed object around the toilet.

[0031] In some embodiments, the sensor is a distance sensor, a human body sensor, or a sound sensor.

[0032] When sensor 2 is a distance sensor, an infrared transmitting system and an infrared receiving system are provided on the distance sensor. The distance information between the human body and the toilet is obtained through the cooperation of the infrared transmitting system and the infrared receiving system. When the distance sensor senses that the distance between the human body and the toilet is gradually increasing, the distance sensor sends an electrical signal to the control system, and the control system controls the driving mechanism to drive the driving push rod 3 to push the flush button to complete the flushing.

[0033] When sensor 2 is a human body sensor, the human body sensor can sense the infrared light emitted by the human body to determine whether the human body is close to or away from the toilet. When the human body sensor detects that the human body has left the toilet, the human body sensor detects the need to flush.

[0034] When the human body sensor senses the need for flushing, the human body sensor sends an electrical signal to the control system, and the control system controls the drive mechanism 1 to start. The movement of the drive mechanism 1 drives the push rod 3 to press the flush button. After a period of time, the control system controls the drive mechanism 1 to move again, so that the push rod 3 moves away from the flush button to complete the flushing work.

[0035] When the sensor 2 is a sound sensor, a detection system is provided inside the sound sensor, and the flushing command issued by the human body is detected by the detection system. When the sound sensor detects the flushing command, the sound sensor sends an electrical signal to the control system to realize the control of the movement of the push rod 3.

[0036] In some embodiments, the push rod 3 contacts the flush button on the outer wall of the toilet under the drive of the driving mechanism, and the driving mechanism continuously drives the push rod 3 to move downward. The push rod 3 pushes the flush button on the outer wall of the toilet and then pushes the flush button inside the toilet tank to complete the flushing.

[0037] In some embodiments, the pressing piece at the bottom end of the push rod 3 extends into the toilet water tank and is connected to the flush button in the toilet water tank. When the push rod 3 moves downward under the action of the driving mechanism, it directly contacts and squeezes the flush button inside the toilet water tank to complete the flushing. There is no need to set a flush button on the outer wall of the toilet, saving production costs.

[0038] In some embodiments, a limiting mechanism is also included, which includes a limiting block 4 and a guide rail 5. The limiting block 4 is connected to the moving end of the driving mechanism 1, and the guide rail 5 is installed in the shell. The limiting block 4 slides in the guide rail 5.

[0039] During the movement of the push rod 3, the cooperation between the limit block 4 and the guide rail 5 ensures the movement direction of the push rod 3 and ensures that the push rod 3 can accurately press the flush button.

[0040] In some embodiments, the driving mechanism 1 includes a motor 12, a reducer 11, a driving screw 13 and a driving nut 14. The motor 12 is fixed inside the shell, the output shaft of the motor 12 is connected to the input shaft of the reducer 11, the output shaft of the reducer 11 is connected to the driving screw 13, the driving screw 13 is connected to the driving nut 14, the driving nut 14 is threadedly connected to the driving screw 13, the end of the driving nut 14 close to the flush button is connected to the push rod 3, and the limit block 4 is set on the driving nut 14.

[0041] After receiving the electrical signal from the sensor 2, the control system controls the motor 12 to start. The rotation of the motor 12 drives the reducer 11 and thus drives the driving screw 13 to rotate. The driving screw 13 drives the driving nut 14 to move toward the end close to the flush button by cooperating with the thread of the driving nut 14, thereby pushing the push rod 3 to move downward, pressing the flush button to complete the flushing. When the push rod 3 pushes the flush button to the bottom end, the motor 12 cannot rotate due to the limiting effect of the limit block 4. After a period of time, the control system controls the motor 12 to reverse, so that the push rod 3 returns to its initial position.

[0042] In some embodiments, the driving mechanism 1 includes a hydraulic cylinder, a moving end of the hydraulic cylinder is connected to the push rod 3, and a limit block 4 is fixed to the moving end of the hydraulic cylinder.

[0043] The control system controls the extension and contraction of the hydraulic cylinder, thereby driving the push rod 3 to move back and forth to complete the flushing work.

[0044] In some embodiments, a position sensor 6 is further included, and at least one position sensor 6 is provided. When one position sensor 6 is provided, the position sensor 6 is provided at an end of the guide rail 5 away from the flush button. When multiple position sensors 6 are provided, multiple position sensors 6 are provided along the length of the guide rail 5.

[0045] When one position sensor 6 is provided, the control system controls the motor 12 to rotate, thereby driving the driving screw 13 to rotate, so that the driving nut 14 moves downward under the action of the guide rail 5 and the limit block 4. After a period of time, the control system controls the motor 12 to reverse, and the driving nut 14 moves upward. When the position sensor 6 senses that the limit block 4 has returned to its initial position, it sends an electrical signal to the control system, and the control system controls the motor 12 to stop rotating to complete the flushing work.

[0046] When there are multiple position sensors 6, during the downward movement of the limit block 4, the position information of the limit block 4 is collected by the position sensor 6 and sent to the control system. After receiving the position information, the control system issues a command to the motor 12. When the control system receives the signal from a position sensor 2 closest to the flush button, the motor 12 is controlled to stop rotating. After a period of time, the motor 12 is controlled to reverse until the control system receives the signal from the uppermost position sensor 2, and the motor 12 stops rotating. At this time, the limit block 4 returns to the initial position and the flushing operation is completed.

[0047] In some embodiments, a voice system is also included, which is electrically connected to the control system. The control unit also includes a display system for detecting and displaying the surrounding environment, and the display system is electrically connected to the application software.

[0048] The environment around the toilet is detected through the display device, and the detected information is sent to the application software to realize remote monitoring of the environment around the toilet.

[0049] In some embodiments, an induction light is also included.

[0050] In some embodiments, the housing is secured to the toilet and / or fixtures around the toilet.

[0051] The housing is fixed to the toilet or to a fixing member around the toilet by a suction cup or a telescopic rod to prevent the housing from moving due to the reaction force when the push rod 3 pushes the flush button, thereby affecting the flushing effect.

[0052] In some embodiments, one end of the shell is abutted against the outer wall of the toilet through a suction cup or a telescopic rod, and the other end of the shell is abutted against the wall around the toilet through a suction cup or a telescopic rod, ensuring the stability of the shell during flushing.

[0053] In some embodiments, the control system is electrically connected to the remote electronic device.

[0054] The control system sends the detected information to the remote electronic device via an electrical signal, and the information detected by the control system is viewed via the remote electronic device.

[0055] When flushing is required, the user operates the remote electronic device, which sends an electrical signal to the control system, so that the control system controls the drive unit to push the push rod 3 to press the flush button, completes the remote control of the drive unit, and realizes the remote implementation of the flushing instruction.
