[0032] like Figures 1 to 9 As shown, the utility model provides a toilet tank sensor panel, focusing on Figure 1-2 As shown, it includes a panel body 1, a mounting bracket 2 and a first elastic member 3; the panel body 1 is used to sense the human body, so as to drive the toilet drain valve 100 to open and drain water to the toilet through electric control. A sensor 15 is provided on the panel body 1. The sensor 15 is used to sense the human body and also includes an electric drainage drive mechanism 300. The sensor 15 is communicatively connected to the electric drainage drive mechanism 300. The electric drainage drive mechanism 300 is transmission-connected to the toilet drain valve 100, driving the toilet drain valve 100 to open and drain water to the toilet. Specifically, the sensor 15 is an infrared sensor. A PCB board (not shown in the figure) and a solenoid valve switch (not shown in the figure) are provided in the electric drainage drive mechanism 300. When the sensor 15 senses a waving motion of a human hand or senses a human body approaching, the collected signal is sent to the PCB board. The PCB board is connected to an external power supply and is electrically connected to the solenoid valve switch for controlling the solenoid valve switch to open or close the toilet drain valve 100, focusing on Figure 6As shown, a first drainage sensing area 16 and a second drainage sensing area 17 are formed on the panel body 1. When the first drainage sensing area 16 senses a human body, the toilet drain valve 100 opens for full drainage. When the second drainage sensing area 17 senses a human body, the toilet drain valve 100 opens for half drainage. Draining the toilet by electric induction is an existing technology and will not be elaborated on in detail. On the basis of the panel body 1 achieving drainage by induction, the utility model drives the panel body 1 to slide by hand to open the toilet drain valve 100. While maintaining the integrity of the panel appearance, manual drainage can be performed in the event of an accidental power outage.

[0033] In this specific embodiment, the mounting frame 2 is fixedly arranged, and the panel body 1 is slidably arranged on the mounting frame 2, and forms an initial position and a drainage position along the sliding path. The panel body 1 is transmission-connected to the toilet drain valve 100, so that when the panel body 1 slides to the drainage position, the toilet drain valve 100 is driven to open and drain water to the toilet. The mounting frame 2 is used to be installed on the toilet water tank 200, combined with Figure 8-9 As shown, the toilet water tank 200 is a hidden water tank, and the toilet water tank 200 is installed in the wall. After the mounting bracket 2 is installed on the toilet water tank 200, the panel body 1 is exposed outside the wall for the hand to press to drive the panel body 1 to slide. The panel body 1 can slide back and forth, up and down, left and right, or diagonally, and can be transmitted and connected to the toilet drain valve 100 to open the toilet drain valve 100. The first elastic member 3 is connected to the panel body 1 and is used to elastically drive the panel body 1 back to the initial position.

[0034] This specific embodiment takes the panel body 1 sliding downward as an example to illustrate its specific structure. The drainage position of the panel body 1 is set directly below the initial position. The panel body 1 slides downward from the initial position to the drainage position, and the panel body 1 slides upward from the drainage position to the initial position.

[0035] Focus on combination Figure 6-7 As shown, the panel body 1 is connected to the toilet drain valve 100 through the transmission assembly 4. The transmission assembly 4 includes a transmission rod 5 and a reversing member 6. The transmission rod 5 extends forward and backward, with its front end connected to the panel body 1 and its rear end connected to the reversing member 6. A clearance hole 22 is provided on the mounting frame 2 for the transmission rod 5 to pass through from front to back. The reversing member 6 is connected to the lifting rod 101 of the toilet drain valve 100. When the panel body 1 slides between the initial position and the drain position, the transmission rod 5 is driven to move forward and backward, so that the reversing member 6 drives the lifting rod 101 to rise and fall, thereby driving the toilet drain valve 100 to open or close to drain water to the toilet. Figure 7As shown, the reversing member 6 includes a rotating shaft 61, which is laterally pivoted on the toilet water tank 200. A swing hook 62 is radially protruded on the rotating shaft 61. The swing hook 62 swings up and down with the pivot of the rotating shaft 61. The swing hook 62 is used to connect the lifting rod 101 of the toilet drain valve 100. A driving arm 63 is also radially protruded on the rotating shaft 61. The transmission rod 5 is connected to the driving arm 63, so that when the panel body 1 slides, the transmission rod 5 moves back and forth to push the driving arm 63 to drive the rotating shaft 61 to pivot, so that the swing hook 62 swings up and down, and drives the lifting rod 101 to rise and fall to open or close the toilet drain valve 100; the connection structure between the swing hook 62 and the lifting rod 101 can be any existing structure for lifting the lifting rod 101 by the swinging of the swing hook 62. Specifically in this embodiment, a lifting hole is formed on the lifting rod 101, and the end of the swing hook 62 is inserted into the lifting hole. Then, in the process of the swing hook 62 swinging upward, it hooks the lifting hole and lifts the lifting rod 101 upward to open the toilet drain valve 100 for drainage. Drainage through the lifting type drain valve switch is an existing technology and will not be elaborated in detail. After the swing hook 62 stops swinging upward, the lifting rod 101 descends to close the drainage. In the process of the lifting rod 101 descending, the lifting hole pulls down the swing hook 62, and the swing hook 62 swings down to reset. The connection structure between the driving arm 63 and the transmission rod 5 can be any existing mechanism that converts the linear motion of the transmission rod 5 into a mechanism for driving the rotating shaft 61 to rotate, and is not specifically limited. In this specific embodiment, the driving arm 63 is a cylindrical structure, and its inner circumference forms an internal thread, and the outer circumference of the transmission rod 5 forms an external thread. The two are threadedly connected, so that the transmission rod 5 is screwed and fixed to the driving arm 63. When the transmission rod 5 moves back and forth, the driving arm 63 drives the rotating shaft 61 to pivot. In this specific embodiment, there are two transmission rods 5, the lifting rod 101 includes a full-row lifting rod and a half-row lifting rod, and the number of reversing members 6 is also two. The swing hook 62 on one reversing member 6 is connected to the full-row lifting rod, and the swing hook 62 on the other reversing member 6 is connected to the half-row lifting rod. The two transmission rods 5 are respectively connected to the two reversing members 6. When the panel body 1 slides downward from the initial position to the drainage position, the full-row lifting rod and the half-row lifting rod are opened at the same time.

[0036] Focus on combination Figure 1-2 As shown, the panel body 1 is provided with an inclined wedge surface 11, and the front end of the transmission rod 5 is wedge-matched with the inclined wedge surface 11, so that when the panel body 1 slides linearly between the initial position and the drainage position along the longitudinal plane, the inclined wedge surface 11 drives the transmission rod 5 to move forward and backward. Specifically, the inclined wedge surface 11 is set backward and tilted upward, focusing on the combination Figure 5 As shown, when the panel body 1 slides downward from the initial position to the drainage position, the inclined wedge surface 11 moves downward, pushing the driving rod 5 to move backward. Figure 5The middle arrow indicates that the drive rod 5 moves backward; of course, in other embodiments, the inclination direction of the inclined wedge surface 11 is changed, and it is set to be inclined downward, or inclined to the left, or inclined to the right, or inclined in other directions. When in use, the panel body 1 can be slid upward, left and right, or obliquely slid to make the inclined wedge surface 11 push the drive rod 5 to move backward.

[0037] Focus on combination Figure 4-5 As shown, the panel body 1 slides up and down relative to the mounting frame 2. The rear side of the panel body 1 is opened. The panel body 1 is mounted on the mounting frame 2 from the open end to the rear. Specifically, the panel body 1 is placed on the mounting frame 2 backward, and its outer side wall surrounds the outer periphery of the mounting frame 2. A limit block 13 is formed on the side wall of the panel body 1. The limit block 13 protrudes on the moving path of the mounting frame 2 in the direction away from the panel body 1, limiting the front and rear movement of the panel body 1 relative to the mounting frame 2. The panel body 1 and the mounting frame 2 are both square structures. The rear side opening of the panel body 1 is a square structure. The longitudinal dimension of the opening on the rear side of the panel body 1 is larger than the longitudinal dimension of the outer diameter of the mounting frame 2, and a longitudinal gap is formed between the two. The longitudinal gap is designed according to the inclination angle of the inclined wedge surface 11 and the specific size of the inclined wedge surface 11, which can just open the toilet drain valve 100 so that the two can slide up and down relative to each other. When in use, when the panel body 1 slides downward, the toilet drain valve 100 is opened, and the first elastic member 3 elastically drives the panel body 1 to slide upward and reset, closing the toilet drain valve 100; the limit block 13 includes a first limit block 131 and a first limit block 132. Two limit blocks 132; the first limit block 131 is formed on the inner top wall of the panel body 1, and a first slot 12 is formed between the first limit block 131 and the inner side wall of the panel body 1. The top side of the mounting frame 2 is provided with a first lock tongue 7 that cooperates with the first slot 12 for sliding up and down. The first elastic member 3 is connected to the bottom side of the first lock tongue 7. The first elastic member 3 is used to push the first lock tongue 7 to insert into the first slot 12. The first lock tongue 7 is provided with a first inclined surface 71 away from the first elastic member 3 to facilitate sliding into or out of the first slot 12; the number of the second limit blocks 132 is two, respectively formed on the panel A second slot 14 is formed on the left and right side walls of the main body 1 and between the inner wall of the panel main body 1. Second lock tongues 8 are slidably provided on the left and right sides of the mounting frame 2, and the second lock tongue 8 is extended left and right. The second lock tongue 8 is connected to a second elastic member 9, so that when the panel body 1 is installed on the mounting frame 2, the second elastic member 9 is used to push the second lock tongue 8 into the second slot 14 to limit the panel body 1 from slipping out of the mounting frame 2. Preferably, a second inclined surface 81 is provided on the end of the second lock tongue 8 facing away from the second elastic member 9 to facilitate sliding in or out of the second slot 14.

[0038] Preferably, the second limiting block 132 is a rear side wall of the second slot 14, the second limiting block 132 forms a stepped structure, so that when the second lock tongue 8 is inserted into the second slot 14, the second limiting block 132 is clamped with the second lock tongue 8, so as to limit the rear movement of the second lock tongue 8, the second limiting block 132 comprises a first rear side wall 141 and a second rear side wall 142, the first rear side wall 141 is formed by extending downward from the bottom end of the second rear side wall 142, the transverse width of the first rear side wall 141 is smaller than that of the second rear side wall 142, so that when the panel body 1 is located at the initial position, the second lock tongue 8 is clamped with the first rear side wall 141, and since the first rear side wall 141 is thin, it is convenient to install and disassemble, so that when the panel body 1 is slid downward to the drainage position, the second lock tongue 8 is clamped with the second rear side wall 142, and in the process of sliding downward of the panel body 1, the inclined wedge surface 11 pushes against the transmission rod 5, so that in the process of moving rearward of the transmission rod 5, the transmission rod 5 may pull the mounting frame 2 to move rearward, and through the clamping of the second rear side wall 142 with the second lock tongue 8, the stability between the panel body 1 and the mounting frame 2 can be effectively improved, so as to avoid that the mounting frame 2 is separated from the panel body 1 in the process of sliding downward of the panel body 1.

[0039] In use, as shown in the arrow in FIG. 10, Figure 9 Figure 9 indicates that the panel body 1 is slid downward, the hand presses downward on the top end of the panel body 1, so that the panel body 1 is slid downward from the initial position to the drainage position and the first elastic member 3 is compressed, the inclined wedge surface 11 moves downward and pushes against the transmission rod 5 to move rearward, the transmission rod 5 pushes against the driving arm 63 to drive the rotating shaft 61 to pivot, so that the swing hook 62 swings upward and drives the pull rod 101 to rise, and the closestool drainage valve 100 is opened; the hand is released, the swing hook 62 stops swinging upward, the pull rod 101 descends, the closestool drainage valve 100 is closed, and in the process of descending of the pull rod 101, the swing hook 62 is swung downward and reset, the rotating shaft 61 is pivoted, the driving arm 63 drives the transmission rod 5 to move forward, and at the same time, the elastic force of the first elastic member 3 drives the panel body 1 to slide upward from the drainage position to the initial position, the panel body 1 is reset, the inclined wedge surface 11 moves upward and is reset, and the transmission rod 5 is reset.
