[0002] For traditional toilets on the current market, their flushing functions almost invariably rely on manual operation. Whenever we use the toilet, users need to search for the flushing switch in the toilet tank and press it to perform flushing. However, such an operation method is not only cumbersome but also hides huge hygienic hazards. Due to this repeated pressing behavior, the flushing button of the toilet is prone to accumulating dirt and bacteria, and these bacteria may be invisible to the naked eye. They breed quietly and threaten our health.

[0003] Today, with the rapid development of technology, people are increasingly pursuing the convenience and intelligence of life. The traditional manual flushing method obviously can no longer meet the needs of modern people.

[0028] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of this disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0029] As Figures 1 to 5 shown, the present utility model provides a side-pull flushing drive device applied to a toilet, which is installed below the side-pull switch 6 of the toilet and includes a housing 1, a drive mechanism 2, and an induction component 3; the drive mechanism 2 includes a linkage component 4 and a drive component 5; the linkage component 4 is used to connect with the side-pull switch 6 of the toilet; the drive component 5 is arranged inside the housing 1 and is drivingly connected with the linkage component 4, and is used to drive the linkage component 4 to reciprocally open or close the side-pull switch 6 of the toilet; the induction component 3 is connected with the drive component 5, and is used to sense and receive an induction signal and input it to the drive component 5 to control the drive component 5 to drive the linkage component 4 to work. There is no need to manually operate the side-pull switch 6 of the toilet, which can effectively improve the intelligence level of the flushing of the toilet 2 and the simplicity of the flushing control operation, and meet the convenient use needs of users.

[0030] Specifically, as Figure 4 shown, the drive component 5 includes a controller 7, a power supply module 8, and an electric motor 9, and the power supply module 8 is electrically connected with the controller 7; the controller 7 is connected with the induction component 3 and is used to receive an externally input induction signal; at the same time, it can also be operated through a wireless remote control and / or a mobile terminal such as a mobile phone to directly send an induction signal to the controller 7 for control.

[0031] Among them, in addition to being powered by the power supply module 8, that is, the battery, the controller 7 can be powered by accessing a power supply through a USB interface 25 provided. The USB interface 25 is arranged on the side wall of the housing 1 and is covered with a USB cover plate 26. When the USB interface 25 is not needed, it can be blocked by the USB cover plate 26 to make the overall device beautiful and tidy.

[0032] The controller 7 is electrically connected with the electric motor 9. The controller 7 includes the functions of battery management and driving the motor, and uses the MCU to control the electric motor 9 to work according to the externally received induction signal. The user triggers the induction component 3 (an in-built or external sensor in the machine body), and the induction component 3 transmits the induction signal to the controller 7. After receiving the induction signal, the controller 7 drives the electric motor 9 to rotate and work, and the electric motor 9 drives the linkage component 4 to reciprocally open or close the side-pull switch 6 of the toilet, thereby realizing automatic flushing.

[0033] As Figure 3 With Figure 7As shown, it is a specific implementation of the linkage component 4. The linkage component 4 includes a pull wire 10 and a wire wheel 11 for tightening and / or loosening the pull wire 10. One end of the pull wire 10 passes through the housing 1 and is connected to the side pull switch 6 of the toilet. If the pull wire is too short at the beginning, a small section of the pull wire 10 can be pulled out through the wire outlet hole 23 by force to adjust the desired length. The other end of the pull wire 10 is tied and wound around the wire wheel 11. The wire wheel 11 is drivingly connected to the electric motor 9. The wire wheel 11 is fixed to the output shaft of the electric motor 8. The electric motor 9 drives the wire wheel 11 to rotate to tighten the pull wire 10, so as to realize that the pull wire 10 pulls the side pull switch 6 of the toilet downward, which is equivalent to pressing the side pull switch 6 of the toilet downward for a flushing operation. The electric motor 9 stops rotating when realizing the downward pulling of the side pull switch 6 of the toilet. After the flushing operation is completed, the electric motor 9 rotates the wire wheel 11 in the opposite direction to loosen the pull wire 10, thereby releasing the side pull switch 6 of the toilet and enabling the side pull switch 6 of the toilet to automatically reset to end the flushing operation. The electric motor 9 stops rotating when realizing the release and reset of the side pull switch 6 of the toilet. The time duration between the electric motor 9 tightening and stopping rotating and loosening can be adjusted for the main controller according to the user's preference or the characteristics of half of the water valves on the market, so as to control the electric motor 9 to immediately or delay for a certain number of seconds to control the length of the flushing time. For example, after pulling the side pull switch 6 of the toilet downward for 3 seconds, the electric motor 9 rotates in the opposite direction to drive the wire wheel 11 to rotate and loosen the pull wire 10, thereby realizing the length of the flushing time, avoiding wasting water resources due to too long flushing time and avoiding incomplete flushing due to too short flushing time. This function cooperates with the drain valve and its settings used by the user himself to achieve the desired effect.

[0034] As Figure 5As shown, it is an embodiment 1 of the sensing component 3 in the utility model, the sensing component 3 is arranged inside the housing 1, the sensing component 3 includes a human body sensor 12, the human body sensor 12 is electrically connected to the controller 7, the human body sensor 12 is a human body sensing switch, which can sense the infrared rays emitted by the sensing component 3 through the reflection of the human body, or sense through the human body sensor 12, the human body sensing switch is also called a pyroelectric human body sensing switch or an infrared intelligent switch, when the user enters the sensing range of the human body sensor 12, the human body sensor 12 can detect the change of the infrared spectrum of the human body, confirming that the user is using it, the human body sensor 12 continues to wait and confirm that the user is in the area, until the user leaves the sensing range of the human body sensor 12, and immediately automatically sends a sensing signal to the controller 7 to control the electric motor 9 to work, the sensing signal is used to control the electric motor 9 to rotate the wire wheel 11 to tighten the pull line 10; The pull wire 10 tightens and pulls the toilet side pull switch 6, which is equivalent to toggling the toilet side pull switch 6 to perform a flushing operation. The electric motor 9 stops rotating after toggling the toilet side pull switch 6; after completing the flushing operation, the electric motor 9 rotates the wire wheel 11 in the opposite direction to loosen the pull wire 10, thereby loosening the toilet side pull switch 6, so that the toilet side pull switch 6 is automatically reset, thereby ending the flushing operation and closing the water valve to allow it to be refilled with water. The electric motor 9 stops rotating after loosening the toilet side pull switch 6 and resetting it.

[0035] Among them Figures 1 to 3 as well as Figure 7 As shown, the housing 1 is provided with a sensing window 13 at a position corresponding to the human body sensor 12. The sensing window 13 is made of a transparent material such as glass or acrylic or a film that filters out infrared rays. The infrared rays of the human body sensor 12 can be emitted and / or received through the sensing window 13, so that the human body sensor can be effectively sensed, and while improving its sensing sensitivity, it can be convenient for users to identify the sensing position and facilitate users to perform sensing triggering.

[0036] like Figure 6As shown, this is the second embodiment of the induction component 3 in the present utility model. The induction component 3 includes a sensor 14 and a signal receiving module 15. In addition to being installed inside the body, the sensor 14 can also be externally placed and set at any position within the toilet 2 where the user can reach and sense, such as on the side wall of the toilet 2, on the seat ring of the toilet 2, on the water tank of the toilet 2, etc. The installation and setting methods can be in the forms of inlaying, attaching, and placing, etc.; the sensor 14 is set at any position outside the toilet 2 where the user can reach and sense, such as on the wall or floor of the toilet, or the user can hold the sensor 14; the sensor 14 is connected to the signal receiving module 15 through a wireless communication module and / or through a wired line to transmit the induction signal. The signal receiving module 15 is electrically connected to the controller 7. After the user triggers and senses the sensor 14, an induction signal is sent to the signal receiving module 15, and the signal receiving module 15 transmits this induction signal to the controller 7 to control the electric motor 9 to work. The specific working method refers to the embodiment of the induction component 3 in the present utility model.

[0037] In order to more precisely control the number of turns of the electric motor 9 when driving the wire wheel 11 to rotate, and to realize that the wire wheel 11 appropriately tightens and / or relaxes the pull wire 10 to operate the flushing switch of the toilet, the following are the specific embodiments for the design of the electric motor 9 for detecting and controlling its rotation:

[0038] The first embodiment is: A travel switch can be set to control the number of turns of the electric motor 9 through the travel switch, so as to realize the travel of the pull wire 10 to accurately complete the operation of the flushing switch.

[0039] The second embodiment is: The electric motor 9 adopts a stepper motor or a motor with an encoder. By sending a step signal from the controller 7 to the electric motor 9, the number of turns of the electric motor 9 can be accurately controlled, thereby avoiding excessive rotation of the wire wheel 11 to tighten and / or relax the pull wire 10.

[0040] The third embodiment is: A current detection circuit is connected in series to the electric motor 9. Since the working current of the electric motor 9 is related to its working load, by detecting the change in current, the tightening and relaxation conditions of the pull wire 10 are determined to judge the working state of the flushing switch, thereby avoiding excessive rotation of the wire wheel 11 to tighten and / or relax the pull wire 10.

[0041] Specifically, as Figure 7As shown, a fastening component 18 is provided at the connection between the pull wire 10 and the side pull switch 6 of the toilet. The fastening component 18 includes a sling 19 and a lock 20. The sling 19 and the lock 20 are respectively arranged corresponding to the pull wire 10 and the side pull switch 6 of the toilet. The pull wire 10 is connected to the side pull switch 6 of the toilet by being fastened to each other through the sling 19 and the lock 20. Through the arrangement of the sling 19 and the lock 20, the installation and / or disassembly between the pull wire 10 and the side pull switch 6 of the toilet can be facilitated, and the disassembly and installation efficiency can be improved. Moreover, the pull wire 10 can be pulled out to a suitable length at will, which is convenient for installing the sling 19 on the side pull switch 6 of the toilet. In order to facilitate the installation on the side pull switch 6 of the toilet without causing damage, a glue-bonding method can be adopted for fixation, that is, for the sling 19 installed on the side pull switch 6 of the toilet, one end thereof is provided with a glue-bonded film, and the film can be directly pasted on the surface of the side pull switch 6 of the toilet. A buckling hole is provided at the other end of the sling 19, and the connection between the two is realized by opening the lock 20 and buckling it with the buckling hole. If the side pull type flushing driving device of the present utility model is not used, it is only necessary to simply remove the side pull type flushing driving device from the toilet 2 and tear off the film pasted on the side pull switch 6 of the toilet, and the original state of the toilet can be restored without damage.

[0042] Specifically, as Figure 2 shown, in order to facilitate the pull wire 10 to pass through the outside and be connected to the side pull switch 6 of the toilet, the housing 1 includes an outer shell 21 and a bottom plate 22 installed at the bottom of the outer shell 21. The outer shell 21 is provided with an outlet hole 23, and the pull wire 10 passes through the outlet hole 23 and is connected to the side pull switch 6 of the toilet.

[0043] As Figure 2 with Figure 3 shown, in order to facilitate the installation and fixation of the present device on the toilet 2 and be connected to the side pull switch 6 of the toilet, the bottom plate 22 is provided with a double-sided tape 24. Therefore, during installation, the present device can be pasted below the side pull switch 6 of the toilet through the double-sided tape 24; at the same time, in addition to the double-sided tape 24, the present device can also be installed and fixed at the toilet 2 by means of a suction cup or magnetic attraction, etc.

[0044] The above is only the preferred embodiment of the present utility model. The present utility model is not limited to the above implementation manners. As long as it achieves the technical effects of the present utility model by the same means, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
