And after the present invention separates the upper cover A1 and the base A2 of the base A, if the upper cover A1 and the base A2 are to be connected, the operator aligns the upper cover A1 and the base A2, and then presses down the upper cover A1 so that the left buckle block A522 of the left elastic buckle A52 and the right buckle block A622 of the right elastic buckle A62 are respectively buckled with the left buckle hole A71 of the left fixing member A7 and the right buckle hole A81 of the right fixing member A8, thereby completing the installation and connection of the upper cover A1 and the base A2, and the whole installation process is also very convenient; a slope inclined from top to bottom to the right is provided on the left side of the left buckle block A522 of the left elastic buckle A52, and a slope inclined from top to bottom to the left is provided on the right side of the right buckle block A622 of the right elastic buckle A62, so that when the upper cover A1 is pressed down, the left buckle block A522 of the left elastic buckle A52 and the right buckle block A622 of the right elastic buckle A62 can be smoothly snapped into the left buckle hole A71 of the left fixing member A7 and the right buckle hole A81 of the right fixing member A8 respectively.

[0059] Cooperate Figure 1 And Figure 3As shown, the film changing seat ring B is of a U-shaped structure, and the two ends of the film changing seat ring B are divided into a movable end B1 and a hinged end B2. The hinged end B1 of the film changing seat ring B is hinged to the base A2 of the base A, and the film outlet A3 and the film collection port A4 of the base A are respectively arranged corresponding to the movable end B1 and the hinged end B2 of the film changing seat ring B; the film changing device C includes a film outlet roller C1, a film collection roller C2 and a film collection motor C3, the film outlet roller C1 and the film collection roller C2 can be rotatably matched in the installation space of the base A, and the film outlet roller C1 and the film collection roller C2 are respectively arranged corresponding to the film outlet A3 and the film collection port A4, the film collection motor C3 is installed in the installation space of the base A and the film collection motor C3 drives the film collection roller to rotate, and the controller E is electrically connected to the film collection motor C3 to control whether the film collection motor C3 works or not. The principle of replacing the sanitary film sleeved on the membrane replacement seat ring B of the present invention is as follows: a clean sanitary film is wound on the film outlet roller C1, the free end of the sanitary film first passes through the outside of the base from the film outlet port A3 and is sleeved on the membrane replacement seat ring B, then the free end of the sanitary film enters the installation space of the base A from the film collection port A4, and finally the free end of the sanitary film is wound on the film collection roller C2; in this way, when the controller E controls the film collection motor C3 to drive the film collection roller C2 to rotate, the film collection roller C2 will roll up the sanitary film and pull the sanitary film sleeved on the membrane replacement seat ring B to move, thereby replacing the sanitary film sleeved on the membrane replacement seat ring B. The film collecting roller C2 is provided with an elastic clip C21, and the free end of the sanitary film can be first wrapped around the elastic clip C21 and then wrapped around the entire side wall of the film collecting roller C2. This can ensure that the friction resistance between the sanitary film and the film collecting roller C2 is large, so that the rotation of the film collecting roller 42 can stably pull the sanitary film; the elastic clip C21 is elastic, so that people can bend the elastic clip C21 to facilitate wrapping the sanitary film around the elastic clip C21.

[0060] Cooperate Figure 5 and Figure 10 As shown, the human body sensor D is installed on the base A and is used to sense human body signals. The controller E is electrically connected to the human body sensor D. The human body sensor D can use a pyroelectric sensor or an infrared photoelectric switch. The sensing direction of the human body sensor D can be oriented obliquely forward and upward, so that as long as people stand in front of the toilet, the human body sensor 3 can sense the human body, and the controller E then controls the membrane changing device C to perform the membrane changing operation. This usage method is more in line with people's habits of using toilets, making it more convenient for people to use. The human body sensor D can be installed in the installation space of the base A. The upper cover A1 of the base A is provided with a window corresponding to the human body sensor D, and the window is equipped with a light-transmitting protective cover A13 to protect the human body sensor D.

[0061] Cooperate Figure 8 and Figure 10As shown, the controller E is installed in the installation space of the base A. The controller E can be fitted in an installation box F. The installation box F is accommodated in the installation space of the base A and is connected to the base A2. The installation box F can be composed of a box base F1 and a box cover F2 that covers the box base F1. The box base F1 is connected to the base A2, and the box cover F2 is detachably connected to the box base F1. The film winding motor C3 of the film changing device C can be installed in the installation box F. The output shaft of the film winding motor C3 extends out of the installation box F and is connected to the film winding roller C2, so that the film winding motor C3 can drive the film winding roller C2 to rotate. Two fitting gaps are respectively formed between the left and right side walls of the installation box F and the left and right side walls of the base base A2. The film outlet roller C1 and the film winding roller 3 can be respectively fitted in the two fitting gaps. The human body sensor D is installed in the installation box F. A fixing seat F4 is fitted on the box cover F2 of the installation box F. The human body sensor D is fitted in the fixing seat F4, so that the human body sensor D is convenient to disassemble and assemble.

[0062] fit Figure 1 、 Figure 3 and Figure 10 As shown, the base A can be fitted with a hinge plate A9 connected to the base A2. The hinge plate A9 passes through the film outlet opening A4, and the end of the hinge plate A9 outside the base A is hinged to the hinge end B2 of the film changing seat ring B. A torsion spring G is fitted at the hinge between the film changing seat ring B and the hinge plate A9. The torsion spring G is used to drive the film changing seat ring B to tilt upward. In the present invention, by setting the torsion spring G, the film changing seat ring B has a tendency to tilt upward. In this way, when the film changing seat ring B is not pressed, the torsion spring G can make the film changing seat ring B tilt upward, so that the bottom of the sanitary film sleeved on the film changing seat ring B is suspended, thereby reducing the resistance when the sanitary film sleeved on the film changing seat ring B is pulled by the film changing device C and avoiding the problems of breakage or jamming of the sanitary film sleeved on the film changing seat ring B. The hinge plate A9 is provided with a cutting portion A91, and the cutting portion A91 can be used to cut the sanitary film, so that the sanitary film can pass through the hinge plate A9 smoothly when the film changing device C pulls the sanitary film.

[0063] fit Figure 1 、 Figure 3 and Figure 10 As shown, the present invention may further include a spare seat ring H. The spare seat ring H is hinged to the base A1 of the base A. The spare seat ring H of the present invention can be used by users who do not like to use sanitary films, while the film changing seat ring B can be used by users who need to use sanitary films. In this way, the applicable range of the present invention is wider; fit Figure 1 As shown, when the spare seat ring H and the film changing seat ring B are in a flat state, the spare seat ring H is located below the film changing seat ring B. In this way, when the spare seat ring H is used alone, the spare seat ring H will not press the sanitary film sleeved on the film changing seat ring B, thus avoiding the breakage of the sanitary film.

[0064] fit Figure 3 and Figure 10As shown in the figure, the present invention may further include a film-out metering device J. The film-out metering device J1 includes a metering roller J1 and a proximity sensor J2. The metering roller J1 is rotatably fitted in the installation space of the base A and the metering roller J1 is arranged parallel to the film-out roller C1. The proximity sensor J2 is fitted in the installation space of the base A and the proximity sensor J2 is electrically connected to the controller E. The metering roller J1 is provided with a proximity component J3 that cooperates with the proximity sensor J2. The controller E measures the number of rotations of the metering roller J1 through the cooperation of the proximity sensor J2 and the proximity component J3. The metering roller J1 of the present invention is used to tension the sanitary film. Thus, due to the frictional force between the sanitary film and the metering roller J1, when the film-receiving roller C2 of the film-changing device C pulls the sanitary film to move, the sanitary film will drive the metering roller J1 to rotate synchronously, so that the number of rotations of the metering roller J1 can reflect the movement amount of the sanitary film. And every time the metering roller J1 rotates one circle, the proximity sensor J2 senses the proximity component J3 once and sends an induction signal to the controller E. The controller E obtains the number of rotations of the metering roller J1 by counting the number of received induction signals. The controller E then calculates and obtains the movement amount of the sanitary film through the number of rotations of the metering roller J1 and the radius at the contact between the metering roller J1 and the sanitary film. It can be seen from this that the controller E of the present invention can obtain the movement amount of the sanitary film through the film-out metering device J. In this way, when the controller E controls the film-receiving motor C3 of the film-changing device C to rotate for film-changing operation, when the movement amount of the sanitary film obtained by the controller E through the film-out metering device J meets the preset value, the controller E controls the film-receiving motor C3 of the film-changing device C to stop rotating and ends the film-changing operation. In this way, the movement amount of the sanitary film can be accurately controlled to ensure that the film-changing device C can completely replace the sanitary film sleeved on the film-changing seat ring B. Among them, since the metering roller J1 will rotate synchronously with the movement of the sanitary film, the number of rotations of the metering roller J1 can accurately reflect the movement amount of the sanitary film, so that the controller E can accurately obtain the movement amount of the sanitary film.

[0065] fit Figure 10As shown, in the present invention, the proximity sensor J2 is a Hall proximity switch, and the proximity component J3 is a magnet. Each time the Hall proximity switch senses the magnetic field of the magnet, it generates an induction signal for the controller E. In the present invention, the cooperation between the Hall proximity switch and the magnet is used to detect the number of turns of the metering roller J1, which is relatively stable and helps to ensure the stability of the usage amount of the hygienic film measured by the present invention. The magnet can be fixed at the end of the metering roller J1 and is eccentrically arranged with the metering roller J1. The Hall switch can be fixed in the connecting seat J4. The connecting seat J4 is fitted in the installation space of the base A and is connected to the base A2. One end of the metering roller J1 can be rotatably connected to the connecting seat J4. It should be noted that the proximity sensor J2 of the present invention can also adopt other proximity switches, and the proximity component is a component that can be sensed by the corresponding proximity switch. As long as the proximity sensor J2 senses the proximity component J3 once and sends an induction signal to the controller E each time the metering roller J1 rotates one circle in the present invention. For example, the proximity sensor J2 can also be a reflective photoelectric proximity switch, and the proximity component J3 is a reflective sheet that actively covers the detection port of the reflective photoelectric proximity switch. Each time the metering roller J1 rotates one circle, the reflective sheet blocks the reflective photoelectric proximity switch once, causing the reflective photoelectric proximity switch to sense the reflective sheet once.
