[0042] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0043] like Figures 1 to 11 As shown, the present invention discloses an intelligent membrane replacement system for toilets, which includes a toilet cover 1 and an intelligent control box 2; wherein the toilet cover 1 includes a base A and a seat ring B hinged to the base A, and the base A is equipped with a membrane replacement device C for replacing the sanitary membrane sleeved on the seat ring B and a remaining amount monitoring device D for monitoring the remaining amount of sanitary membrane usage; the intelligent control box 2 includes a box body 21, a control module 22 installed in the box body 21 and a transceiver antenna 23 for wireless communication with a cloud server, the transceiver antenna 23 is equipped with the box body 21 and the transceiver antenna 23 is electrically connected to the control module 22, and the control module 22 is communicatively connected to the membrane replacement device C and the remaining amount monitoring device D.

[0044] The control module 22 of the present invention is communicatively connected to the remainder detection device D for monitoring the remaining usage of the sanitary membrane, and the control module 22 can communicate wirelessly with the cloud server through the transceiver antenna 23. Therefore, when the control module 22 detects that the remaining usage of the sanitary membrane is insufficient through the remainder monitoring device D, the control module 22 automatically sends the information that the sanitary membrane needs to be replaced to the cloud server through the transceiver antenna 23, and the cloud server then sends the corresponding information to the operation and maintenance personnel, so that the operation and maintenance personnel can replace the sanitary membrane in time.

[0045] In the present invention, the surface of the box body 21 of the smart control box 2 may be provided with a QR code for mobile terminals to scan and access a cloud server. Users can scan the QR code via a mobile terminal (such as a smartphone or tablet) to access the cloud server, which then issues instructions to the control module 22 of the smart control box 2 to control the control module 22. The present invention allows users to control the control module 22 through the cloud server by viewing advertisements or paying a fee. This allows businesses that provide the present invention's smart toilet membrane replacement system to users to profit from advertising or user payments. The QR code can be printed on a sticker that is adhered to the surface of the box body 21; the QR code can also be applied to the surface of the box body 21 by spraying.

[0046] Cooperate Figure 2 and Figure 4As shown, the base A of the toilet cover 1 includes a detachably connected upper cover A1 and a base A2, an openable and closable installation cavity is formed between the upper cover A1 and the base A2, and a film outlet A3 and a film receiving port A4 communicating with the installation cavity are provided on the front side of the base A1. The film outlet A3 and the film receiving port A4 can be formed between the upper cover A1 and the base A2, and the film outlet A3 and the film receiving port A4 can also be provided on the base A2; the seat ring B is a U-shaped structure, and the two ends of the seat ring B are divided into a movable end B1 and a hinged end B2, and the hinged end B1 of the seat ring B is hinged to the base A2 of the base A, and the film outlet A3 and the film receiving port A4 of the base A are respectively The film-changing device C includes a film-discharging roller C1 for outputting sanitary film, a film-collecting roller C2 for winding the sanitary film, and a film-collecting motor C3 for driving the film-collecting roller C2 to rotate. The film-discharging roller C1 and the film-collecting roller C2 can both be rotatably fitted in the mounting cavity of the base A, and the film-discharging roller C1 and the film-collecting roller C2 are respectively arranged corresponding to the film-discharging port A3 and the film-collecting port A4. The film-collecting motor C3 is installed in the mounting cavity of the base A and the film-collecting motor C3 drives the film-collecting roller to rotate. The control module 22 is communicated with the film-collecting motor C3 to control whether the film-collecting motor C3 works or not. In the present invention, the working principle of the film changing device C is as follows: a clean sanitary film is wound on the film discharging roller C1, the free end of the sanitary film first passes through the base A from the film discharging port A3 and is sleeved on the seat ring B, then the free end of the sanitary film enters the installation cavity of the base A from the film receiving port A4, and finally the free end of the sanitary film is wound on the film receiving roller C2; when the film receiving motor C3 drives the film receiving roller C2 to rotate, the film receiving roller C2 will rewind the sanitary film and pull the sanitary film sleeved on the seat ring B to move, thereby replacing the sanitary film sleeved on the seat ring B. Figure 2 and Figure 6 As shown, 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 ensures 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.

[0047] Cooperate Figure 2 and Figure 4As shown, the base A of the toilet lid 1 can be equipped with a hinged plate A5 connected to the base A2. The hinged plate A5 passes through the film receiving opening A4, and the end of the hinged plate A5 outside the base A is hinged to the hinged end B2 of the seat ring B. The hinge between the seat ring B and the hinged plate A5 is equipped with a torsion spring E, which is used to drive the seat ring B to tilt upward. The present invention provides the seat ring B with an upward tendency by providing the torsion spring E. When the seat ring B is not under pressure, the torsion spring E can cause the seat ring B to tilt upward, causing the bottom of the sanitary membrane mounted on the seat ring B to be suspended in the air, thereby reducing the resistance of the sanitary membrane mounted on the seat ring B when the membrane replacement device C is pulled, thereby preventing the sanitary membrane mounted on the seat ring B from being damaged or stuck. The hinged plate A5 is provided with a cutting portion A51, which can be used to cut the sanitary membrane, so that the sanitary membrane can pass smoothly through the hinged plate A5 when the membrane replacement device C pulls the sanitary membrane.

[0048] Cooperate Figure 2 As shown, the remaining amount monitoring device D includes a reflective photoelectric sensor D1 installed in the installation cavity of the base A, and the reflective photoelectric sensor D1 can be fixed on the base A2 of the base A. The reflective photoelectric sensor D1 is communicatively connected with the control module 22 of the intelligent control box 2; the light emitter of the reflective photoelectric sensor D1 is used to emit light to the sanitary film wound on the film discharge roller C1, and the light receiver of the reflective photoelectric sensor D1 is used to receive the light reflected by the sanitary film wound on the film discharge roller C1; the working principle of the remaining amount monitoring device D of the present invention is: when the sanitary film wound on the film discharge roller C1 has sufficient remaining amount, the light emitted by the light emitter of the reflective photoelectric sensor D1 will be reflected by the sanitary film wound on the film discharge roller C1. The light is emitted and received by the light receiver of the reflective photoelectric sensor D1, causing the reflective photoelectric sensor D1 to emit a first signal indicating that there is sufficient remaining sanitary film; and as the film-winding motor C3 continuously drives the film-winding roller C2 to wind up the sanitary film and replace the sanitary film sleeved on the seat ring B, the thickness of the sanitary film wound on the film-discharging roller C1 gradually decreases. When the thickness of the sanitary film wound on the film-discharging roller C1 decreases to the point where the light emitted by the light emitter of the reflective photoelectric sensor D1 does not irradiate the sanitary film, the remaining sanitary film wound on the film-discharging roller C1 is insufficient, and the light receiver of the reflective photoelectric sensor D1 cannot receive the light emitted by the light emitter, causing the reflective photoelectric sensor D1 to emit a second signal indicating that there is insufficient remaining sanitary film.

[0049] Cooperate Figure 2 and Figure 4As shown, the toilet cover 1 may also include a film-discharging metering device F, which includes a metering roller F1 and a proximity sensor F2; the metering roller F1 is rotatably fitted in the mounting cavity of the base A, and the metering roller F1 is arranged parallel to the film-discharging roller C1; the proximity sensor F2 is fitted in the mounting cavity of the base A, and the proximity sensor F2 is communicatively connected to the control module 22 of the intelligent control box 2; the metering roller F1 is provided with a proximity component F3 that cooperates with the proximity sensor F2, and the present invention measures the number of rotations of the metering roller F1 by cooperating with the proximity sensor F2 and the proximity component F3. The metering roller F1 of the present invention is used to tension the sanitary film. Due to the friction between the sanitary film and the metering roller F1, when the film-rewinding roller C2 of the film-changing device C rewinds the sanitary film, the sanitary film drives the metering roller F1 to rotate synchronously, so that the number of rotations of the metering roller F1 can reflect the output of the sanitary film. Each time the metering roller F1 rotates one circle, the proximity sensor F2 senses the proximity component F3 once and outputs a counting signal. In this way, the number of rotations of the metering roller F1 can be obtained by measuring the number of outputs of the counting signal. Then, the output of the sanitary film can be calculated based on the number of rotations of the metering roller F1 and the radius of the contact point between the metering roller F1 and the sanitary film. It can be seen from this that The present invention can obtain the output of the sanitary film through the film metering device F. In this way, when the film-receiving motor C3 of the film-replacing device C is controlled to rotate and perform the film-replacing operation, when the output of the sanitary film obtained by the film-replacing metering device F meets the preset value, the film-receiving motor C3 of the film-replacing device C is controlled to stop rotating and the film-replacing operation is ended. In this way, the output of the sanitary film can be accurately controlled to ensure that the film-replacing device C can completely replace the sanitary film sleeved on the seat ring B. Since the metering roller F1 rotates synchronously with the movement of the sanitary film, the number of rotations of the metering roller F1 can accurately reflect the output of the sanitary film, so that the present invention can accurately obtain the output of the sanitary film. Figure 4As shown, the proximity sensor F2 is a Hall proximity switch, and the proximity component F3 is a magnet. The Hall proximity switch outputs a counting signal each time it senses the magnetic field of the magnet. The present invention detects the number of turns of the metering roller F1 by cooperating with the Hall proximity switch and the magnet, which is relatively stable and helps to ensure the stability of the output of the metered sanitary film of the present invention. The magnet can be fixed to the end of the metering roller F1 and the magnet is eccentrically arranged with the metering roller F1. The Hall switch can be fixed in the connecting seat F4, which is matched in the mounting cavity of the base A and is connected to the base A2. One end of the metering roller F1 can be rotatably connected to the connecting seat F4. It should be noted that the proximity sensor F2 of the present invention may also adopt other proximity switches, and the proximity component is a component that can be sensed by the corresponding proximity switch. In the present invention, it is sufficient as long as the proximity sensor F2 senses the proximity component F3 once and sends a counting signal every time the metering roller F1 rotates one circle. For example, the proximity sensor F2 may also be a reflective photoelectric proximity switch, and the proximity component F3 is a reflective sheet that movably covers the detection port of the reflective photoelectric proximity switch. Every time the metering roller F1 rotates one circle, the reflective sheet blocks the reflective photoelectric proximity switch once, causing the reflective photoelectric proximity switch to output a counting signal.

[0050] Cooperate Figure 2 and Figure 4 As shown, the toilet cover 1 may also include an electronic limit device G that is in communication with the control module 22. The electronic limit device G is used to limit the free rotation of the film roller C1 and release the rotation restriction of the film roller C1. When the electronic limit device limits the free rotation of the film roller C1, people cannot pull the sanitary film freely, thereby preventing people from maliciously pulling the sanitary film. Figure 5As shown, the side wall of the film-discharging roller C1 is provided with a limit plate C11, and the end face of the limit C11 is provided with at least two limit blocks C12, and the limit blocks C12 are centrally symmetrically distributed about the rotation center line of the film-discharging roller C1; the electronic limit device G is installed in the installation cavity of the base A and is communicatively connected with the control module 22 of the intelligent control box 2, and the electronic limit device G has a retractable limit rod, which moves in and out of the gap between two adjacent limit blocks C12, and the side of the limit rod moves against the side of the rotation direction of each limit block C12. In the present invention, when the sanitary film of the membrane replacement device C needs to be replaced, the limit rod of the electronic limit device G retracts and exits the gap between two adjacent limit blocks C12, preventing the limit rod from abutting against the limit blocks C12, allowing the film delivery roller C1 to rotate freely. When the sanitary film of the membrane replacement device C does not need to be replaced, the limit rod of the electronic limit device G extends and enters the gap between two adjacent limit blocks C12. The side of the limit rod abuts against the rotational side of the two adjacent limit blocks C12, restricting the free rotation of the film delivery roller C1. This prevents people from freely pulling the sanitary film, thereby preventing malicious human pulling of the sanitary film. The electronic limit device G can be a push-pull electromagnet, the push rod of which serves as the limit rod; the electronic limit device G can also be a telescopic motor, the output shaft of which serves as the limit rod.

[0051] Cooperate Figure 4As shown, a toilet cover controller H can be fitted in the base mounting cavity of the toilet cover 1, and the film collecting motor C3 of the film changing device C, the reflective photoelectric sensor D1 of the remaining amount monitoring device D, the proximity sensor F2 of the film discharging metering device F and the electronic limit device G are electrically connected to the toilet cover controller H, and the toilet cover controller H is connected to the control module 22 of the intelligent controller 2 via wireless communication or wired communication; wherein when the control module 22 receives the film changing instruction issued by the cloud server through the transceiver antenna 23, the control module 22 sends a signal to the toilet cover controller H sends a film change command. After receiving the command, toilet controller H first controls the electronic limiter G to release the rotation limit on the film delivery roller C1. It then controls the film take-up motor C3 to drive the film take-up roller C2 to rotate and change the film. Simultaneously, toilet controller H uses the film delivery metering device F to measure the output of the sanitary film. When the output of the sanitary film reaches a preset value, toilet controller H controls the film take-up motor C3 of the film change device C to stop rotating. At the same time, toilet controller H controls the electronic limiter G to restrict the free rotation of the film delivery roller C1. When the remaining sanitary film wrapped around the film delivery roller C1 is insufficient, the reflective photoelectric sensor D1 sends a second signal indicating insufficient sanitary film to the toilet lid controller H. The toilet lid controller H then sends this information to the control module 22. The control module 22 then automatically sends a message to the cloud server via the transceiver antenna 23 indicating that the sanitary film needs to be replaced. The toilet lid controller H, electronic limit device G and film collecting motor C3 can be installed in an installation box L, which can be spliced ​​together by a box cover L1 and a box seat L2. The installation box L is fitted in the installation cavity of the base A and is connected to the base A2 of the base A. The installation box L can be provided with a battery compartment, which contains a toilet lid battery J for powering the toilet lid controller H, the electronic limit device G, the proximity sensor F2, the reflective photoelectric sensor D1 and the film collecting motor C3; two fitting gaps can be formed between the left and right side walls of the installation box L and the left and right side walls of the base A2, respectively, and the film delivery roller C1 and the film collecting roller 3 can be fitted in the two fitting gaps respectively. The limit rod of the electronic limit device G extends out of the installation box L, and the output shaft of the film collecting motor C3 extends out of the installation box L and is connected to the film collecting roller 3.

The fragrance spraying device 24 includes a solenoid valve 241 and a spray can 242 for containing fragrance gas. The box body 21 is provided with a fragrance spraying port 2121. The inlet and outlet of the solenoid valve 241 are respectively connected to the nozzle 2421 of the spray can 242 and the fragrance spraying port 2121 of the box body 21. The solenoid valve 241 is electrically connected to the control module 22, which controls the opening and closing of the solenoid valve 241. The intelligent control box 2 and toilet lid 1 of the present invention are used in the bathroom. The user can control the opening and closing of the solenoid valve 241 through the control module 2. When the solenoid valve 241 is opened, the fragrance gas in the spray can 242 is sprayed out of the box body 21 through the solenoid valve 241 and the fragrance spraying port 2121, thereby improving the ambient odor of the bathroom. The present invention can be that the user first scans the code through the smart phone to access the cloud server, and the cloud server then sends the fragrance instruction to the control module 22 according to the user's fragrance demand, and the control module 22 then controls the solenoid valve 241 to open for a certain period of time.

When people want to install the spray can 242 on the mounting seat 214, they first put the spray can 242 into the mounting groove 2141. The spray can 242 is installed in the mounting groove 2141, and then the pressing buckle 215 is rotated so that the pressing buckle 215 squeezes one end of the spray can 242 and drives the other end of the spray can 242 against the side wall of the mounting groove 2141, thereby fixing the spray can 242 in the mounting groove 2141, which is very convenient for installation.
