Description

Technical Field

[0001] This application relates to the field of bathroom equipment, and specifically discloses a cleaning mechanism. This application also discloses a smart toilet seat using the cleaning mechanism and a toilet using the cleaning mechanism. Background Technology

[0002] Existing smart toilets are equipped with a washing device for cleaning the anus and / or vulva. This device includes a water outlet that sprays water to rinse the anus and / or vulva. However, because there is a certain distance between the water outlet and the user's anus and vulva, the outlet is often located below and behind the user. The cleaning fluid is sprayed from below and forward and upward, resulting in a relatively fast flow rate. Especially when rinsing the anal area, the cleaning fluid flowing through the anal area can easily wet and contaminate the male or female external genitalia in front of the anus. The fast flow rate also causes the cleaning fluid to splash and flow, wetting a large area of ​​the user's body. Furthermore, while the rinsing area of ​​the existing toilet's washing device is relatively fixed, individual differences among users or variations in the same user's sitting posture each time mean that the rinsing cannot be accurately aimed at the user's anus and / or vulva, easily wetting and contaminating parts of the body outside the target cleaning area. Summary of the Invention

[0003] To address one of the technical problems existing in the prior art, this application provides a cleaning mechanism equipped with a cleaning hood. When cleaning is required, the cleaning hood is placed around the anus of the toilet user to prevent cleaning fluid from leaking out of the opening of the cleaning hood and to limit the area to be wetted to the area covered by the cleaning hood, thereby preventing the cleaning fluid from wetting and contaminating the male or female external genitalia in front of the anus during rinsing.

[0004] A cleaning mechanism according to a first aspect of the present invention, applied to a toilet, includes a cleaning hood, a first cleaning nozzle, and a displacement driving mechanism. The cleaning hood has an opening at the top and a drain outlet at the bottom; the opening and the drain outlet of the cleaning hood are connected. The outlet of the first cleaning nozzle is located inside the cleaning hood, and the first cleaning nozzle sprays cleaning fluid onto the anal area of ​​the user of the toilet for rinsing and cleaning. The displacement drive mechanism is installed on the toilet and is connected to the cleaning cover. The cleaning cover has a storage position and a working position. The cleaning cover is driven by the displacement drive mechanism to switch between the storage position and the working position. When the cleaning cover is in the storage position, it does not affect the normal use of the toilet. When the cleaning cover is in the working position, the cleaning cover is driven to change its spatial position by the displacement driving mechanism, so that the opening of the cleaning cover is placed around the anus of the user of the toilet to prevent the cleaning liquid from leaking out of the opening of the cleaning cover to the outside of the cleaning cover. The first cleaning nozzle rinses and cleans the anal area.

[0005] The cleaning mechanism according to the first aspect of the present invention has at least the following beneficial effects: The cleaning mechanism of this application includes a cleaning hood, which has a storage position and a working position. The cleaning hood is driven to switch between the storage position and the working position by a displacement driving mechanism.

[0039] In the description of this application, for the convenience of describing this patent, the terms "front, back, left, right, up, and down" are introduced to facilitate the description of spatial relationships. The specific coordinates are based on the coordinate system in the accompanying drawings. It should be understood that the description of spatial relationships does not indicate or imply that the device or element referred to must have a specific orientation, a specific positional relationship, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0040] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The present invention will be further described with reference to several embodiments.

[0041] This invention provides a cleaning mechanism 01, such as Figure 2 , Figure 6 and Figure 8 As shown, the cleaning mechanism 01 is applied to a toilet. It should be noted that the toilet described in this invention includes a latrine, a commode chair, a bedpan, and other forms of toilets. Figure 2 , Figure 6 and Figure 8 The diagrams shown are schematics of the cleaning mechanism 01 applied to a toilet. However, the cleaning mechanism 01 of the present invention can also be applied to commode chairs, bed urinals and other types of toilets, which will not be discussed in detail here.

[0042] Specifically, refer to Figures 2 to 4, Figures 6 to 11 In several embodiments provided by the present invention, the cleaning mechanism 01 of the present invention includes at least a cleaning hood 7, a first cleaning nozzle 8 and a displacement driving mechanism 02.

[0043] like Figure 3 , Figure 7 , Figures 9 to 11 As shown, the cleaning cover 7 is a hollow, regular or irregular cylindrical structure. An opening is provided at the top of the cleaning cover 7 to cover the area around the anus of the toilet user, blocking the cleaning fluid from reaching the anal area. This ensures the cleaning fluid is confined to the area covered by the opening of the cleaning cover 7, preventing splashing and leakage. The cleaning cover 7 can be made of one or more materials selected from metal, ceramic, glass, and plastic, with ceramic being the most preferred material because its glazed surface becomes smooth, making it less prone to dirt adhesion and facilitating surface cleaning. Furthermore, a coating can be applied to the surface of the cleaning cover 7, such as a wear-resistant oleophobic or hydrophobic coating. This coating makes the surface of the cleaning cover 7 smooth, preventing liquids, cleaning agents, excrement, and dirt from adhering to the surface and making it easy to rinse off, thus facilitating cleaning and self-cleaning. Figure 3 As shown, in the first embodiment provided by the present invention, the cross-section of the cleaning hood 7 can be a regular shape such as a rounded rectangle, circle, or ellipse, which is simple in structure, easy to manufacture, and helps to reduce costs. Alternatively, the cross-section of the cleaning hood 7 can be an irregular shape; furthermore, as... Figure 7 , Figure 9 and Figure 11 As shown in the second, third, and fourth embodiments provided, the curve of the upper opening of the cleaning cover 7 can also be set to conform to the ergonomic curve around the human anus, so that the upper opening of the cleaning cover 7 can fit more closely to the part of the human body that is in contact, which is more effective in blocking the cleaning liquid and at the same time increases the comfort of use.

[0044] like Figure 7 , Figures 9 to 11 As shown in the second, third and fourth embodiments provided, a drain port 7a is provided at the lower part of the cleaning hood 7, and an operable drain valve is provided on the drain port 7a. After the drain valve is opened, the sewage in the cleaning hood 7 is discharged through the drain port 7a.

[0045] The first cleaning nozzle 8 is mounted on the cleaning hood 7, such as Figure 3 , Figure 10 and Figure 11 The first and fourth embodiments provided are shown in ( Figure 7 , Figure 9The provided second and third embodiments conceal the first cleaning nozzle 8. The cleaning cover 7 in the above embodiments has a mounting hole 7b for mounting the first cleaning nozzle 8. The first cleaning nozzle 8 is used to spray cleaning fluid onto the anal area of ​​the toilet user for rinsing and cleaning. The first cleaning nozzle 8 is connected to a main water supply pipe 14, which is connected to a main water supply source, including a tap water pipe. In some embodiments, such as... Figure 10 and Figure 11 As shown, the main liquid supply pipe 14 is connected to the liquid supply element of the support platform 6 via a quick connector 15. The quick connector 15 facilitates disassembly, assembly, and maintenance. The outlet of the first cleaning nozzle 8 is located inside the cleaning hood 7, and preferably, the outlet of the first cleaning nozzle 8 is arranged obliquely upwards to achieve the effect of spraying cleaning liquid upwards and forwards, resulting in better cleaning. Alternatively, the outlet of the first cleaning nozzle 8 can be arranged only forwards or only upwards; this invention does not impose specific limitations on this. Because the outlet of the first cleaning nozzle 8 is located inside the cleaning hood 7, it is close to the anus for rinsing during operation. Furthermore, when the cleaning hood 7 is placed around the anus, it prevents the cleaning liquid from wetting and contaminating the body parts outside the cleaning hood 7. Therefore, the outlet of the first cleaning nozzle 8 can have a larger cutoff area. Specifically, the total intercepting area of ​​the outlet of the first cleaning nozzle 8 in this invention is between 0.12 square centimeters and 2.5 square centimeters. A larger intercepting area results in a larger flow rate of the cleaning fluid column and a larger cleaning area, leading to better cleaning performance. It should be noted that this invention does not limit the total intercepting area of ​​the outlet of the first cleaning nozzle 8; the total intercepting area can be outside the range of 0.12 square centimeters to 2.5 square centimeters. Furthermore, the flow velocity of the cleaning fluid sprayed from the first cleaning nozzle 8 is generally selected between 0.5 m / s and 2.8 m / s. Of course, a flow velocity greater than 2.8 m / s can also be selected for high-flow, high-velocity rinsing to produce a better cleaning effect. In contrast, the water outlet of existing smart toilets is generally a round hole with a diameter of about 2 mm, and the interception area of ​​the outlet is about 0.03 square centimeters. The flow velocity of the cleaning fluid at the outlet is generally about 3.2 meters per second. The interception area of ​​the water outlet in existing smart toilets is small, the flow rate of the cleaning fluid column is small, and the flow velocity is relatively high. When rinsing the anal area, the cleaning area is small and the impact is strong, which can cause some discomfort. When the cleaning mechanism 01 of this invention is working, the interception area of ​​the outlet of the first cleaning nozzle 8 is large, the flow rate of the cleaning fluid column is high, and the flow velocity is relatively low. When rinsing the anal area, the cleaning area is large, and the impact of the water flow can be appropriately reduced, thus reducing discomfort. The first cleaning nozzle 8 of this invention can adopt various structural forms, such as... Figure 3 As shown, in the first embodiment, the first cleaning nozzle 8 can be a spray pipe, or as... Figure 10 and Figure 11 As shown, in the fourth embodiment, the first cleaning nozzle 8 can also be a small shower head with several slit-shaped liquid outlets. The longitudinal section of the shower head along the spray direction is trapezoidal or fan-shaped, and the shower head sprays out a fan-shaped liquid column. The shower head outlets have a large interception area, resulting in a larger cleaning area and a larger cleaning liquid flow rate, making the cleaning more thorough. Regardless of the structural form of the first cleaning nozzle 8, it should fall within the protection scope of this invention.

[0046] The cleaning hood 7 has at least a storage position and a working position. Driven by the displacement drive mechanism 02, the cleaning hood 7 switches between the storage position and the working position. For example... Figure 2 , Figure 6 and Figure 8 As shown in the first, second, and third embodiments, the displacement drive mechanism 02 is mounted on the toilet. Figures 3 to 4 , Figure 7 , Figures 9 to 11 As shown, the displacement drive mechanism 02 includes a support platform 6, a moving part, and a control device. The moving part is connected to the support platform 6, and the cleaning cover 7 is mounted on the support platform 6. When the moving part moves, it drives the support platform 6 to move. The control device is used to control the movement of the moving part, so that the cleaning cover 7 on the support platform 6 can accurately reach the required position. When the cleaning cover 7 changes position and reaches the storage position through the drive of the displacement drive mechanism 02, the cleaning cover 7 is in a stored state, which does not affect the user of the toilet from defecating or urinating into the toilet bowl. When the cleaning cover 7 changes position and reaches the working position through the drive of the displacement drive mechanism 02, the opening of the cleaning cover 7 is positioned around the anus of the user of the toilet. The first cleaning nozzle 8 sprays and cleans the anal area. The opening of the cleaning cover 7 around the anus of the user of the toilet can effectively prevent the cleaning liquid from leaking out of the opening of the cleaning cover 7 to the outside of the cleaning cover 7.

[0047] The cleaning mechanism 01 of the present invention is provided with a cleaning cover 7, and the outlet of the first cleaning nozzle 8 is located inside the cleaning cover 7. When the cleaning mechanism 01 of the present invention is working, the opening of the cleaning cover 7 is placed around the anus of the user of the toilet, and the first cleaning nozzle 8 rinses and cleans the anus. The cleaning cover 7 effectively prevents the cleaning liquid from leaking out of the opening of the cleaning cover 7 to the outside of the cleaning cover 7, avoiding splashing and flowing of the cleaning liquid during rinsing and wetting or contaminating the male or female external genitalia in front of the anus, and limiting the wet area to the area covered by the cleaning cover 7. With the outlet of the first cleaning nozzle 8 located inside the cleaning cover 7, the outlet of the first cleaning nozzle 8 can use a larger interception area to rinse the anal area close to it, so as to form a larger liquid column to clean the anal area, making the cleaning more thorough, and can appropriately reduce the flow rate of the cleaning liquid column, reducing the discomfort when the cleaning liquid column rinses the anal area.

[0048] Furthermore, such as Figure 3 , Figure 7 , Figures 9 to 11 As shown, the edge of the upper opening of the cleaning cover 7 (where it contacts the human body) is preferably provided with a curved transition. It should be noted that the curved transition here includes both the structure in which the inner and outer walls of the cleaning cover 7 are connected by a curved transition at the upper opening, and the connection between the lines that form the shape of the upper opening of the cleaning cover 7 by a curved transition. By using a curved transition, the sharp corners and edges at the upper opening of the cleaning cover 7 can be reduced or even completely eliminated, avoiding injury to the human body from sharp corners and edges, and improving comfort.

[0049] Furthermore, the opening of the cleaning cover 7 of the present invention can also be provided with a sealing ring made of soft material to further improve sealing performance and comfort. In addition, since the sealing ring covers the upper opening of the cleaning cover 7, the requirements for the curve design of the upper opening of the cleaning cover 7 can be appropriately reduced, thereby simplifying some processes.

[0050] Furthermore, such as Figure 3 and Figure 4As shown, in the first embodiment provided by the present invention, the cleaning cover 7 can also be composed of an upper cover component 7e and a lower cover component 7f; wherein, the upper cover component 7e serves as a support, and an opening is provided at the upper part of the upper cover component 7e. In use, the open cover is placed around the user's anus. The upper cover component 7e is generally made of a rigid material. The upper cover component 7e is mounted on the support platform 6, and a mounting hole 7b is provided on the upper cover component 7e. The first cleaning nozzle 8 passes through the mounting hole 7b, so that the first cleaning nozzle 8... The liquid outlet is located inside the upper cover component 7e; the lower cover component 7f is generally made of soft material and fits over the bottom opening of the upper cover component 7e. A drain port 7a is located at the bottom of the lower cover component 7f, and the opening of the upper cover component 7e and the drain port 7a of the lower cover component 7f are connected. The lower cover component 7f can deform and bend. When the cleaning cover 7 is stored in the storage box 3, the lower cover component 7f deforms and bends, saving vertical space and facilitating the miniaturization of the storage box 3. Furthermore, the lower cover component 7f can be designed to be replaceable, allowing users to easily replace it.

[0051] In addition, the cleaning cover 7 can also be composed of an outer cover component and an inner cover component. The outer cover component does not contact the human body, only the inner cover component contacts the human body. The outer cover component serves as a supporting frame and has openings at both the top and bottom. The inner cover component has an opening at the top. When in use, the opening of the inner cover component is placed around the user's anus. The lower part of the inner cover component has a drain port, and the opening of the inner cover component is connected to the drain port at the bottom of the inner cover component. After the inner cover component is fitted inside the outer cover component, the outer cover component snaps into and supports the inner cover component, fixing the position of the inner cover component and preventing it from falling off. When in use, only the inner cover component contacts the user. The inner cover component has a mounting hole, through which the first cleaning nozzle passes, so that the liquid outlet of the first cleaning nozzle is located inside the inner cover component. The inner cover component is preferably made of inexpensive materials, such as plastic or rubber bags, or rigid paper materials with a waterproof film. This allows for easy replacement of the inner cover component. The ultimate goal of this design is to create a simple, portable, disposable, and replaceable component (inner cover component). This design is suitable for use on toilets in public places. By replacing the disposable component (inner cover component) before use, cross-infection can be avoided. Furthermore, the first cleaning nozzle 8 can also be integrally mounted on the inner cover component. When the cleaning cover 7 is composed of an outer cover component and an inner cover component, the first cleaning nozzle 8 is equipped with a liquid collection tube for connecting to the liquid supply pipe on the support platform 6. Both the liquid collection tube and the inner cover component are disposable and replaceable. The first cleaning nozzle 8, the inner cover component, and the liquid collection tube are all disposable components, making installation and replacement more convenient.

[0052] The displacement drive mechanism 02 includes a support platform 6, a moving part, and a control device. The cleaning hood 7 is mounted on the support platform 6, the moving part is connected to the support platform 6, and the control device is connected to the moving part. The displacement drive mechanism 02 is used to drive the cleaning hood 7 to change its spatial position, allowing the cleaning hood 7 to reach the desired position. Specifically, the control device controls the movement of the moving part, which in turn controls the movement of the support platform 6. The moving part can drive the support platform 6 to change the spatial position of the cleaning hood 7 on the support platform 6, thereby allowing the cleaning hood 7 to reach the desired position.

[0053] The motion section includes at least one motion device. The motion device constituting the motion section can take many forms, such as electric actuators, pneumatic / hydraulic cylinder propulsion devices, airbag lifting devices, robotic arms, electric displacement vehicles, etc. It should be noted that the aforementioned electric linear actuator includes a drive motor, a transmission mechanism, a lead screw, a nut, a motion output, and a base connection. The drive motor is connected to the control device, the motion output is the motion output end of the electric linear actuator, and the base connection is used to fix the electric linear actuator. The drive motor can drive the lead screw to rotate via the transmission mechanism. The rotation of the lead screw drives the nut on the guide rail to move linearly. The nut is connected to the motion output, and the nut drives the motion output to move linearly. Alternatively, the drive motor can drive the nut to rotate via the transmission mechanism. The lead screw is connected to the motion output, and the motion output restricts the lead screw from rotating, or the guide rail restricts the lead screw from rotating. The rotation of the nut drives the lead screw to move linearly along its longitudinal axis. The lead screw is connected to the motion output, and the lead screw drives the motion output to move linearly. The drive motor is preferably a servo motor or a stepper motor. It should also be noted that the aforementioned robotic arm is preferably a multi-joint robotic arm 21 with multiple degrees of freedom. The robotic arm can be in the form of a series robotic arm or a parallel robotic arm. Furthermore, the motion unit can have various combinations of motion devices. For example, the motion unit can be a combination of at least one set of electric actuators, or a combination of at least one set of pneumatic / hydraulic cylinder propulsion devices, or a multi-degree-of-freedom robotic arm, or a combination of a multi-degree-of-freedom robotic arm and at least one electric actuator, or a combination of an electric displacement vehicle and at least one set of electric actuators, or a combination of at least one airbag lifting device and at least one set of electric actuators, etc.

[0054] The moving part will now be described in detail with reference to several embodiments provided in this application.

[0055] like Figure 2As shown, in the first embodiment of the present invention, the cleaning mechanism is located behind the toilet seat. It should be noted that the position of the cleaning mechanism can vary depending on actual requirements. The cleaning mechanism can also be located to the side or front of the toilet seat, and can also be located at positions such as above and behind, below and behind, above and to the side, below and to the side, above and to the front, or below and to the front of the toilet. This patent does not limit its placement in these positions. Figure 3 , Figure 4As shown, the moving part of the cleaning mechanism consists of three sets of electric actuators: a first lifting electric actuator 10, a second lifting electric actuator 11, and a front and rear electric actuator 12. The first lifting electric actuator 10 includes a first base connecting part 10a, a first lifting motor 10b, a first lead screw 10c, and a first lifting output part 10d. The output end of the first lifting motor 10b is connected to the first lead screw 10c. A nut is provided on the first lifting output part 10d, and the nut of the first lifting output part 10d cooperates with the first lead screw 10c. The second lifting electric actuator 11 includes a second base connecting part 11a, a second lifting motor 11b, a second lead screw 11c, and a second lifting output part 11d. The output end of the second lifting motor 11b is connected to the second lead screw 11c. A nut is provided on the second lifting output part 11d, and the second lifting output part 11d cooperates with the first lead screw 10c. The nut portion of the cleaning arm 12d engages with the second lead screw 11c; the front and rear electric push rod device 12 includes a third base connecting part 12a, a third motor 12b, a third lead screw 12c, and a cleaning arm 12d. The output end of the third motor 12b is connected to the third lead screw 12c. A nut portion is provided on the cleaning arm 12d, and the nut portion of the cleaning arm 12d engages with the third lead screw 12c; wherein, the first lead screw 10c and the second lead screw 11c are arranged vertically, the third lead screw 12c is arranged in the front-rear direction, and the third lead screw 12c can be arranged horizontally or inclined. Preferably, part or all of the cleaning arm 12d is parallel to the third lead screw 12c; the support platform 6 is provided at the front end of the cleaning arm 12d. The support platform 6 and the cleaning arm 12d can be an integral structure, or the support platform 6 and the cleaning arm 12d are not an integral structure, and the support platform 6 is installed on the front end of the cleaning arm 12d. The base connection portion of the first lifting electric push rod device 10 and the second lifting electric push rod device 11 is used to fix the first lifting electric push rod device 10 and the second lifting electric push rod device 11 to the toilet. The first lifting electric push rod device 10 and the second lifting electric push rod device 11 are arranged front and back. The motion output portion of the first lifting electric push rod device 10 and the second lifting electric push rod device 11 is connected to the third base connection portion 12a of the front and rear electric push rod devices 12. That is, the front and rear electric push rod devices 12 are connected to the motion output portion of the first lifting electric push rod device 10 and the second lifting electric push rod device 11. The first lifting electric push rod device 10 and the second lifting electric push rod device 11 can drive the third base connection portion 12a on the front and rear electric push rod devices 12 to move up and down, so as to drive the support platform 6 to move up and down. The front and rear electric push rod devices 12 are used to drive the washing arm 12d to move in the back and forth direction, so as to drive the support platform 6 to move back and forth.

[0056] Furthermore, such as Figure 4As shown, the washing arm 12d forms a certain angle with the horizontal plane, with the front end of the washing arm 12d lower and the rear end higher. When the washing arm 12d moves forward, the washing cover 7 on the front end of the washing arm 12d moves from the upper rear to the lower front. Because the anus is located below the toilet seat when the user is sitting on it, when the user defecates, the washing cover 7 is in the storage position, at which time the washing cover 7 is above the user's anus. At this time, the height of the upper opening of the washing cover 7 is higher than the height of the user's anus. If the forward and backward movement direction of the washing cover 7 is parallel to the horizontal plane, the forward and backward movement path of the washing cover 7 will be blocked by the user's body, and the washing cover 7 cannot reach the user's anus. When the washing arm 12d forms a sufficiently large angle with the horizontal plane, and the front end of the washing arm 12d is lower and the rear end higher, when the washing arm 12d moves forward, the washing cover 7 on the front end of the washing arm 12d moves from the upper rear to the lower front. During the forward movement, the washing cover 7 also has a downward displacement, which can avoid the user's body, and the washing cover 7 can reach the user's anus. When storing, it follows the same path back. When anal cleaning is required, the cleaning cover 7 moves forward and downward to the working position. When the cleaning cover 7 reaches below the anus, the motion output parts of the first lifting electric push rod device 10 and the second lifting electric push rod device 11 simultaneously move upward, causing the cleaning cover 7 to rise to contact and conform to the area around the user's anus. When the vertical displacement of the motion output parts of the first lifting electric push rod device 10 and the second lifting electric push rod device 11 is not the same, the angle between the horizontal planes of the cleaning arm 12d can be changed to change the angle between the cross-section of the cleaning cover 7 and the horizontal plane. This angle change allows the cleaning cover 7 to better conform to the user's body. After cleaning the anal area, the first lifting electric push rod device 10 and the second lifting electric push rod device 11 activate, driving the cleaning cover 7 to move downward first, and then the front and rear electric push rod devices 12 activate, causing the cleaning cover 7 to move from the lower front to the upper rear, finally bringing the cleaning cover 7 to the storage position.

[0057] It is readily understood that in other embodiments, only one set of lifting electric actuators and one set of front and rear electric actuators may be provided. The base connection of the lifting electric actuator fixes the lifting electric actuator to the toilet, and the motion output of the lifting electric actuator connects to the base connection of the front and rear electric actuators. Furthermore, in other embodiments, when the washing arm 12d is horizontally arranged, to ensure that the height of the upper opening of the washing cover 7 is lower than the height of the user's anus, it is necessary to increase the thickness of the toilet seat and / or add a buttock-supporting inner seat ring to the toilet seat. Increasing the thickness of the toilet seat and adding a buttock-supporting inner seat ring both raise the user's anus position, reserving vertical space for the front and rear movement of the washing cover 7, so that when the washing cover 7 is in the storage or working position, the height of the upper opening of the washing cover 7 is lower than the height of the user's anus. Based on this, when the user defecates, the cleaning cover 7 is in the storage position, that is, the cleaning cover 7 is located below and behind the user's anus; when it is necessary to clean the anus, the cleaning cover 7 moves forward. When the cleaning cover 7 reaches below the anus, the motion output part of the lifting electric push rod device moves upward, and the cleaning cover 7 rises to contact and fit around the user's anus; at this time, the cleaning cover 7 is preferably rotatably mounted on the support platform 6. When the cleaning cover 7 contacts the human body, the angle between the cross-section of the cleaning cover 7 and the horizontal plane can change automatically so that the cleaning cover 7 fits the user's body better; after the anal area is cleaned, the cleaning cover 7 first moves downward, and then moves from front to back, and the cleaning cover 7 reaches below and behind the user's anus. At this time, the cleaning cover 7 is in the storage position.

[0058] like Figure 6 and Figure 7As shown, in the second embodiment provided by the present invention, the moving part includes a multi-joint robotic arm 21, preferably a five-bar linkage robotic arm. In this embodiment, the base end 21a of the multi-joint robotic arm 21 is disposed inside the storage box 3, and the free end 21b of the multi-joint robotic arm 21 is connected to the support platform 6. Driven by the multi-joint robotic arm 21, the cleaning cover 7 can switch between a storage position and a working position. The advantage of using a robotic arm is that it does not require guide rails, making it easy to work in confined spaces and reducing the size of the cleaning mechanism 01. Furthermore, when the multi-joint robotic arm 21 is a five-bar linkage robotic arm, and the free end of the five-bar linkage robotic arm moves back and forth on a plane parallel to the horizontal plane, in order to ensure that the initial height of the upper opening of the cleaning cover 7 is lower than the height of the user's anus, it is necessary to increase the thickness of the toilet seat and / or add a buttock-supporting inner seat ring to the toilet seat. Based on this, in order to achieve the lifting and lowering action of the cleaning cover 7, multiple vertical displacement devices 22 are provided on the support platform 6. The vertical displacement device 22 can be at least one of an electric push rod device, a winch lifting device, or a cylinder / hydraulic cylinder device. In this embodiment, the vertical displacement device 22 is a winch lifting device. The vertical displacement devices 22 are separately arranged on both sides or at the four corners of the cleaning cover 7. A winch motor 22a is provided on each vertical displacement device 22. The vertical displacement device 22 is used to lift and lower the cleaning cover 7, so that the opening of the cleaning cover 7 ultimately covers the area around the anus. When the user defecates, the cleaning cover 7 is in the storage position, that is, the cleaning cover 7 is located below and behind the user's anus. At this time, the height of the upper opening of the cleaning cover 7 is lower than the height of the user's anus. When it is necessary to clean the anus, the cleaning cover 7 moves forward under the drive of the five-bar linkage robotic arm. When the cleaning cover 7 reaches below the anus, the up-down displacement device 22 is activated, causing the cleaning cover 7 to move upward. The cleaning cover 7 rises to contact and fit around the user's anus. After the anal area is cleaned, the up-down displacement device 22 is activated, and the cleaning cover 7 first moves downward. Then, the cleaning cover 7 moves backward under the drive of the five-bar linkage robotic arm and returns to the storage position.

[0059] like Figure 8 and Figure 9As shown, in the third embodiment of the present invention, the moving part includes a linearly arranged track 23a and an electric displacement cart 23. The track 23a is set on the toilet and is a foldable track, which is divided into a toilet bowl section track and a storage box section track. The toilet bowl section track can be flipped backward for storage, and during operation, it is flipped forward and laid on the toilet bowl. The electric displacement cart 23 moves only on the track 23a, and the support platform 6 is set on the electric displacement cart 23. The electric displacement cart 23 is provided with at least one set of wheels 23b, and each set of wheels 23b includes one axle and two wheels 23b. Specifically, in this embodiment, the electric displacement cart 23 is provided with two axles and four wheels 23b; the wheels 23b always roll on the track 23a. The electric displacement vehicle 23 is equipped with a wheel axle motor 23c that drives the axle to rotate. The wheel axle motor 23c drives the axle to rotate through a worm gear transmission device. The rotation of the axle drives the wheels 23b to rotate, causing the electric displacement vehicle 23 to move back and forth along the track 23a. The electric displacement vehicle 23 is equipped with several vertical displacement devices 22 and a horizontal electric push rod device 24. The base connection of the transverse electric push rod device 24 is mounted on the electric displacement vehicle 23. The motion output part of the transverse electric push rod device 24 is equipped with a vertical displacement device 22, and the motion output end of the vertical displacement device 22 is mounted on the support platform 6. Specifically, the transverse electric push rod device 24 includes a transverse lead screw arranged in the left-right direction and a transverse motor 24a that drives the transverse lead screw to rotate. The vertical displacement device 22 is provided with a screw hole that cooperates with the transverse lead screw. The transverse lead screw passes through the screw hole on the vertical displacement device 22. When the transverse motor 24a drives the transverse lead screw to rotate, the vertical displacement device 22 can move in the left-right direction along the transverse lead screw, and finally drive the support platform 6 on the vertical displacement device 22 to move in the left-right direction. Since the forward and backward movement of the electric displacement cart 23 and the movement of the support platform 6 driven by the lateral electric push rod device 24 in the forward, backward, left and right directions are all on a plane parallel to the horizontal plane, in order to make the initial height of the upper opening of the cleaning cover 7 lower than the height of the user's anus, it is necessary to increase the thickness of the toilet seat and / or add a buttock pad inner seat ring on the toilet seat. On this basis, it is necessary to set up a vertical displacement device 22 to drive the lifting and lowering movement of the support platform 6, so that the opening of the cleaning cover 7 on the support platform 6 is finally covered around the anus. The vertical displacement device 22 can be at least one of the electric push rod device, the winch lifting device, or the airbag lifting device, and the vertical displacement device 22 is separately set on both sides or at the four corners of the cleaning cover 7.When the user defecates, the cleaning cover 7 is in the storage position, that is, the cleaning cover 7 is located below and behind the user's anus. At this time, the height of the upper opening of the cleaning cover 7 is lower than the height of the user's anus. When it is necessary to clean the anus, the electric displacement cart 23 moves forward along the track 23a. When the cleaning cover 7 reaches below the anus, the horizontal electric push rod device 24 drives the support platform 6 to move left and right, so that the cleaning cover 7 is aligned with the midline of the user's body on the toilet. The vertical displacement device 22 is activated, and the cleaning cover 7 rises to contact and fit around the user's anus. After the anal area is cleaned, the cleaning cover 7 moves downward first under the action of the vertical displacement device 22, and then the electric displacement cart 23 moves backward along the track 23a back to the storage position.

[0060] Furthermore, in the second and third embodiments described above, multiple vertical displacement devices 22 are provided. When the vertical displacement devices 22 are controlled separately, the angle between the support platform 6 and the horizontal plane can be changed by controlling the movement path of different vertical displacement devices 22, thereby changing the angle between the cross-section of the cleaning cover 7 and the horizontal plane. This angle change can make the cleaning cover 7 fit the user's body better.

[0061] like Figure 10 and Figure 11As shown, in the fourth embodiment of the present invention, the moving part includes a fourth electric push rod device arranged in a front-to-back direction, and the base connection part of the fourth electric push rod device is disposed on the toilet. Specifically, the fourth electric push rod device includes a fourth lead screw 25, a fourth motor 25a that drives the fourth lead screw 25 to rotate, a first guide rail 25b, and a first moving bracket 6a. The first moving bracket 6a is provided with a screw hole that mates with the fourth lead screw 25, and a first guide sliding hole that mates with the first guide rail 25b. The first guide rail 25b serves to limit and guide the movement of the first moving bracket 6a and to bear the weight. The fourth lead screw 25 passes through the corresponding screw hole on the first motion bracket 6a. When the fourth motor 25a drives the fourth lead screw 25 to rotate, the fourth lead screw 25 and the first guide rail 25b cooperate to make the first motion bracket 6a move back and forth along the first guide rail 25b under the rotational drive of the fourth lead screw 25. Furthermore, in order to improve the stability of the movement and load-bearing capacity of the first motion bracket 6a, first guide rails 25b with parallel axes can be provided on the left and right sides of the first motion bracket 6a respectively, and the fourth lead screw 25 is set on one side of the first motion bracket 6a, with the axes of the fourth lead screw 25 and the first guide rail 25b being parallel to each other. In addition, a transverse electric push rod device 24 is provided on the first motion bracket 6a, the base connection part of the transverse electric push rod device 24 is provided on the first motion bracket 6a, and a second motion bracket is provided on the motion output part of the transverse electric push rod device 24. Specifically, the transverse electric actuator 24 includes a transverse lead screw arranged in the left-right direction, a transverse motor 24a driving the transverse lead screw to rotate, a second guide rail, and a second motion support. The second motion support is provided with a screw hole that mates with the transverse lead screw, and a second guide sliding hole that mates with the second guide rail. The second guide rail serves to limit and guide the movement of the second motion support and bear the weight. The transverse lead screw passes through the corresponding screw hole on the second motion support. When the transverse motor 24a drives the transverse lead screw to rotate, the transverse lead screw and the second guide rail cooperate to make the second motion support move left and right along the second guide rail under the rotation drive of the transverse lead screw. Furthermore, in order to improve the stability of the movement and weight bearing of the second motion support, second guide rails with parallel axes can be provided on the front and rear sides of the second motion support, and the axes of the transverse lead screw and the second guide rails are parallel to each other. Since the forward and backward movement of the first motion support and the left and right movement of the second motion support in this embodiment are all performed on a plane parallel to the horizontal plane, and a cleaning cover 7 is connected to the second motion support, in order to make the initial height of the upper opening of the cleaning cover 7 lower than the height of the user's anus, it is necessary to increase the thickness of the toilet seat and / or add a buttock pad inner seat ring to the toilet seat. On this basis, a second vertical displacement device is provided on the second motion support, and a support platform 6 is provided on the second vertical displacement device. The second vertical displacement device is used to realize the lifting and lowering movement of the cleaning cover 7 on the support platform 6.The second motion support is equipped with two second vertical displacement devices. The base connection of the second vertical displacement device is connected to the second motion support. The two second vertical displacement devices are arranged front and rear. The support platform 6 is rotatably and slidably connected to the motion output of the two second vertical displacement devices. When the user defecates, the cleaning cover 7 is in the storage position, that is, the cleaning cover 7 is located below and behind the user's anus. At this time, the height of the upper opening of the cleaning cover 7 is lower than the height of the user's anus. When it is necessary to clean the anus, the fourth electric push rod device is activated, driving the support platform 6 to move forward. When the cleaning cover 7 reaches below the anus, the horizontal electric push rod device 24 drives the support platform 6 to move left and right, so that the cleaning cover 7 is aligned with the midline of the user's body on the toilet. The second vertical displacement device is activated, and the cleaning cover 7 rises to contact and fit around the user's anus. After cleaning the anal area, the cleaning cover 7 moves downward first under the drive of the second vertical displacement device, and then the fourth electric push rod device drives the support platform 6 to move backward, returning to the storage position. Of course, in this embodiment, the support platform 6 can be connected to the motion output end of the second vertical displacement device through a cleaning arm. The cleaning arm extends forward a certain distance, and the front end of the cleaning arm is connected to the support platform 6.

[0062] It should be noted that the moving parts of the present invention are not limited to the types disclosed in the above embodiments. Any structure that can drive the support platform 6 to move so as to change the spatial position of the cleaning cover 7 on the support platform 6 falls within the scope of the moving parts of the present invention. Of course, two or more moving parts can be provided in the storage box 3, and each moving part is provided with the support platform 6 and the cleaning cover 7.

[0063] Furthermore, the displacement drive mechanism 02 of the present invention includes a control device (not shown in the figure). The control device is connected to the moving part and controls the movement of the moving part by controlling its position, posture, trajectory, operation sequence, and action time in the workspace, so that the cleaning cover 7 on the support platform 6 reaches the desired position. The control device includes various sensors, among which the controller includes an image-assisted positioner connected to the control device. The image-assisted positioner includes at least one camera, which is mounted on at least one of the support platform 6 or the cleaning cover 7. The camera feeds back the acquired image information to the control device. The control device determines the spatial position of the cleaning cover 7 based on the image information fed back by the camera and controls the movement of the moving part to bring the cleaning cover 7 to the desired position. The image-assisted positioner also includes an illumination component and a laser pointer. The illumination component provides sufficient auxiliary light for the camera to capture images. The laser pointer projects a light spot onto the user's body on the toilet seat to assist in determining the positional relationship between the anus and the cleaning cover 7, so that the cleaning cover 7 can accurately cover the user's anus.

[0064] Furthermore, such as Figure 1 and Figure 2 , Figure 5 and Figure 6 , Figure 8 As shown in the first, second, and third embodiments, the control device further includes a control panel 5. The control panel 5 is equipped with a touchscreen that can display image information fed back from the camera. Users can control the functions by manipulating the control panel 5, including but not limited to: starting the cleaning function, stopping the cleaning function, adjusting the position (e.g., using directional keys for position adjustment), disinfection, and blowing air. In the embodiments provided by this invention, the control panel 5 is fixed to the toilet seat by a foldable bracket. The foldable bracket is composed of several connecting rods 5a and universal adapters 5b, allowing the foldable bracket to move, rotate, and fold. The control panel 5 is located at the end of the foldable bracket, such as... Figure 1 As shown; the control panel 5 can be moved to the side of the toilet so as not to obstruct the user from sitting on or getting off the toilet; when the user sits on the toilet, the control panel 5 on the foldable bracket can be moved to the front of the toilet for easy operation.

[0065] Furthermore, such as Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown in the second, third, and fourth embodiments, an observation window 7d is provided at the lower part of the cleaning hood 7. A transparent cover, preferably glass, is provided on the observation window 7d. The cover is sealed to the observation window 7d to prevent liquid leakage. Below the observation window 7d, a camera, lighting components, and a laser pointer (not shown in the figure) are located. The camera, lighting components, and laser pointer are positioned below the cover, and the camera captures images of the interior of the cleaning hood 7 through the cover. When the cleaning mechanism 01 is working, the lighting components are turned on to supplement light, and the laser pointer projects a light spot onto the user's body. The spatial position of the cleaning hood 7 is adjusted according to the position of the light spot projection, so that the cleaning hood 7 more accurately covers the user's anus. Furthermore, the camera can capture images of the interior of the cleaning hood 7 and display them on the control panel 5, allowing the user to observe the flushing effect and ensure a more thorough flush.

[0066] Furthermore, such as Figures 1 to 2 , Figures 5 to 6 , Figures 8 to 9 As shown in the first, second, and third embodiments, the cleaning mechanism 01 of the present invention further includes a storage box 3. Only one storage box 3 may be provided, such as... Figure 5 and Figure 6 As shown; storage box 3 can also be set in multiple forms, such as Figure 1 and Figure 2The illustrated embodiment includes a first storage box 3a and a second storage box 3b; the storage box 3 can be installed as an external accessory above the toilet body 1, such as... Figures 1 to 2 , Figures 5 to 6 As shown, the storage box 3 can also be fixedly installed inside the toilet (not shown in the figure). The storage box 3 can be a detachable box, or it can be a box-like space integrated with the toilet. An openable airtight door 4 is provided at the front of the storage box 3. The airtight door 4 can have various connection and opening methods, such as hinged to the storage box 3 and opened by rotation. Figure 2 As shown; alternatively, the airtight door 4 can also be slidably installed in front of the storage box 3 and opened by sliding to both sides (not shown in the figure), and the present invention does not specifically limit this. The storage box 3 is used to store the cleaning cover 7 and the displacement drive mechanism 02. Figure 9 The vertical plane P shown is the plane where the sealed door 4 is located. This plane P is the interface between the storage position and the working position. This plane P separates the storage box 3 and the toilet bowl. It is easy to see that plane P is an imaginary plane and does not affect the entry and exit of the components. When the cleaning cover 7 and the displacement drive mechanism 02 are both inside the storage box 3, and the cleaning cover 7 and the displacement drive mechanism 02 do not pass through plane P, the sealed door 4 is in the closed state, and the cleaning cover 7 is in the storage position, which does not affect the normal use of the toilet. When the displacement drive mechanism 02 drives the cleaning cover 7 to switch from the storage position to the working position, the sealed door 4 opens, the cleaning cover 7 passes through plane P, enters the toilet bowl area, and finally reaches the working position. After the cleaning mechanism 01 completes its work, the displacement drive mechanism 02 drives the cleaning cover 7 to switch from the working position to the storage position. The cleaning cover 7 passes through plane P from the toilet bowl area and returns to the storage box 3. The sealed door 4 closes, and the cleaning cover 7 returns to the storage position. The airtight door 4 is designed to physically separate the storage box 3 from the toilet bowl. When the cleaning cover 7 is in the stored position, the airtight door 4 is closed, separating the storage box 3 from the outside. The airtight door 4 prevents liquid and dirt from the toilet bowl area from falling into the storage box 3, thus avoiding contamination of the cleaning cover 7 and the displacement drive mechanism 02. Using the storage box 3 to store the cleaning cover 7 and the displacement drive mechanism 02 protects them from contamination and makes the toilet more neat and aesthetically pleasing. In addition, when the storage box 3 is detachable, it makes it easier to move the cleaning cover 7 and the displacement drive mechanism 02.

[0067] Furthermore, as a preferred embodiment, the storage box 3 may also be equipped with a disinfection device (not shown in the figure), which includes at least one of an ultraviolet lamp and an ozone generator. Ultraviolet light is generated by the ultraviolet lamp, or ozone is generated by the ozone generator, thereby disinfecting the cleaning cover 7 and the displacement drive mechanism 02 in their stored state inside the storage box 3.

[0068] Furthermore, as a preferred embodiment, the cleaning mechanism 01 may also be equipped with a cleaning cover 7 heater (not shown in the figure). The cleaning cover 7 heater is located at least one position on the support platform 6 or inside the storage box 3. The cleaning cover 7 heater is used to heat the cleaning cover 7 to a temperature close to that of the human body, thereby improving the comfort of the user when using the cleaning cover 7.

[0069] Furthermore, such as Figure 3 and Figure 4 , Figure 10 and Figure 11 As shown in the first and fourth embodiments, the cleaning mechanism 01 further includes a second cleaning nozzle 9, which is mounted on at least one of the support platform 6 or the cleaning hood 7. The second cleaning nozzle 9 cleans the vulva of the female user. The second cleaning nozzle 9 is connected to a second main water supply pipe, which is connected to a main water supply source, including a tap water pipe. The second cleaning nozzle 9 is provided with a plurality of nozzles 9a. The second cleaning nozzle 9 is located outside the cleaning hood 7 and in front of the cleaning hood 7. The second cleaning nozzle 9 is used to clean the vulva of the woman. The second cleaning nozzle 9 is preferably configured to match the shape of the vaginal vestibule area of ​​the woman. The second cleaning nozzle 9 is designed as a trapezoid with a narrower upper section and a wider lower section to facilitate insertion into the vaginal vestibule area and to open the labia minora on both sides. Figure 3 and Figure 4 , Figure 10 and Figure 11 The second cleaning nozzle 9 shown has a trapezoidal shape in both its left and right longitudinal sections. The nozzles 9a are distributed on the top and sides of the second cleaning nozzle 9. This structure allows for a more comprehensive cleaning of the female genital area. It should be noted that the second cleaning nozzle 9 can be configured to clean in contact with the genital area, or it can be configured to clean without contact with the genital area.

[0070] Furthermore, such as Figure 10 and Figure 11As shown in the fourth embodiment, to improve cleanliness, a circulating cleaning device is provided on the cleaning mechanism 01. The circulating cleaning device includes a circulating opening 7c, a circulating pipe 27, a circulating valve, and a circulating drive mechanism. The circulating opening 7c is located in the lower part inside the cleaning hood 7. One end of the circulating pipe 27 is connected to the circulating opening 7c, and the other end is connected to the first cleaning nozzle 8 via a main liquid supply pipe 14. The circulating valve is located on the cleaning hood 7 and controls the opening and closing of the drain port 7a and the circulating opening 7c. During circulating cleaning operation, the drain port 7a is closed and the circulating opening 7c is open; when circulating cleaning is not operating, the drain port 7a is open and the circulating opening 7c is closed. The circulating drive mechanism is connected to the circulating pipe 27. During circulating cleaning operation, the cleaning fluid, driven by the circulating drive mechanism, enters the circulating pipe 27 from inside the cleaning hood 7 through the circulating opening 7c. After passing through the circulating pipe 27, it is sprayed out by the first cleaning nozzle 8 to rinse the anus, and the cleaning fluid returns to the cleaning hood 7. The cleaning fluid circulates repeatedly between the cleaning hood 7 and the circulating cleaning device under the drive of the circulating drive mechanism. The cleaning solution can be tap water, an aqueous solution containing cleaning agents, or an aqueous solution of medicine, hereinafter the same. By circulating the cleaning solution through a circulating cleaning device, continuous local rinsing with a cleaning agent solution can be achieved, enhancing the cleaning effect and conserving cleaning agents; it can also achieve continuous local rinsing with a medicinal solution, conserving medication.

[0071] Furthermore, such as Figure 10 and Figure 11As shown in the fourth embodiment, to enhance the effect of cyclic cleaning, a liquid reservoir is also provided in the cleaning mechanism 01. In this embodiment, a first liquid reservoir 29 and a second liquid reservoir 30 are respectively provided. The first liquid reservoir 29 is provided with a first water supply pipe 29b, and the first liquid reservoir 29 is connected to the main liquid supply pipe 14 via a first liquid supply pipe 29a to connect to the first cleaning nozzle 8. A first liquid supply device is provided along the path of the first liquid supply pipe 29a, which provides power for the liquid flow between the first liquid reservoir 29 and the first cleaning nozzle 8. The second liquid reservoir 30 is provided with a second water supply pipe 30b, and the second liquid reservoir 30 is connected to the main liquid supply pipe 14 via a second liquid supply pipe 30a to connect to the first cleaning nozzle 8. A second liquid supply device is provided along the path of the second liquid supply pipe 30a, which provides power for the liquid flow between the second liquid reservoir 30 and the first cleaning nozzle 8. With the above setup, any of the liquid supply devices can provide the cleaning solution from the reservoir to the first cleaning nozzle 8 during operation. The first reservoir 29 is typically used to add chemicals, while the second reservoir 30 is typically used to add cleaning agents to achieve different cleaning effects. Both the first reservoir 29 and the second reservoir 30 are equipped with a stirrer to ensure the cleaning solution is evenly mixed with the cleaning agent or chemical. The first reservoir 29 has an openable inlet for adding chemicals for localized application. The second reservoir 30 is connected to a cleaning agent container via a pipe. The cleaning agent container contains cleaning agent, which is then pumped into the second reservoir 30 by a pumping device. After entering the second reservoir 30, the cleaning agent is diluted with water and stirred evenly by the stirrer before use.

[0072] The specific process of circulating cleaning is as follows: In the first case, circulating cleaning can be divided into two stages. The first stage is the circulating rinsing of the cleaning agent aqueous solution or chemical solution. The second stage is the circulating rinsing of the water in the circulating cleaning device. After the first stage of circulating cleaning is completed, the drain outlet 7a is opened, and the circulating drive mechanism continues to operate until the cleaning liquid in the circulating pipe 27 and the circulating drive mechanism is drained. Then, the circulating drive mechanism stops operating, and the circulating opening 7c is closed. During the second stage of circulating cleaning, the circulating valve controls the drain outlet 7a to open, and the circulating opening 7c is also opened. Water from the main supply pipe 14 is sprayed out through the first cleaning nozzle 8 to rinse the anal area and the inside of the cleaning hood 7. At the same time, the water in the main supply pipe 14 flows in the reverse direction through the circulating pipe 27. The circulating drive mechanism drives the water flow in the reverse direction, and the water flows out through the circulating opening 7c. After rinsing is completed, the first cleaning nozzle 8 stops spraying liquid, and the circulating drive mechanism continues to operate until the water in the circulating pipe 27 and the circulating drive mechanism is drained. Then, the circulating drive mechanism stops operating, and the circulating opening 7c is closed. In addition, the second scenario includes four stages: Stage 1: The drain outlet 7a is open, and the circulation opening 7c is closed; water from the main supply pipe 14 is sprayed through the first cleaning nozzle 8a to clean fecal matter or secretions adhering to the anal area. Stage 2: First, the circulation valve controls the drain outlet 7a to close and the circulation opening 7c to open; then, the solution in the first reservoir 29 is pumped by the first supply device and sprayed through the first cleaning nozzle 8a to rinse the anal area, and the solution enters the cleaning hood 7 for future circulation cleaning; or, the cleaning solution in the second reservoir 30 is pumped by the second supply device and sprayed through the first cleaning nozzle 8a to rinse the anal area, and the cleaning solution enters the cleaning hood 7 for future circulation cleaning. Stage 3: The circulation drive mechanism operates, driving the solution or cleaning solution in the cleaning hood 7 to enter the circulation pipe 27 through the circulation opening, and sprayed through the first cleaning nozzle 8a to rinse the anal area. The cleaning solution then re-enters the cleaning hood 7, thus achieving localized circulation rinsing with the solution or cleaning solution. At the end of this stage, the circulation valve controls the opening of the drain port 7a and the circulation opening 7c, and the circulation drive mechanism continues to operate until the cleaning fluid in the circulation pipe 27 and the circulation drive mechanism is completely drained. Fourth stage: The circulation valve controls the opening of the drain port 7a and the circulation opening 7c; water from the main supply pipe 14 is sprayed out through the first cleaning nozzle 8a to rinse the anal area and the inside of the cleaning hood. At the same time, the water from the main supply pipe 14 enters the circulation pipe 27 and flows in reverse within the circulation pipe 27. The circulation drive mechanism drives the water flow in reverse, and the water flows out through the circulation opening. After rinsing is completed, the main supply pipe 14 stops supplying liquid, and the circulation drive mechanism continues to operate until the water in the circulation pipe 27 and the circulation drive mechanism is completely drained. The circulation drive mechanism then stops operating, and the circulation valve controls the circulation opening 7c to close.

[0073] Furthermore, such as Figure 10 and Figure 11As shown in the fourth embodiment, the cleaning mechanism 01 includes an enema tube 26, which is mounted on the support platform 6 or the cleaning hood 7, and is located outside the cleaning hood 7. The position of the enema tube 26 can be adjusted using the position adjustment function provided by the control panel 5, so that the opening end of the enema tube 26 reaches its working position (inside the anal canal or rectum). On the one hand, the enema tube 26 can be used before defecation, whereby liquid is injected into the user's large intestine through the anus, which can help users with constipation to defecate smoothly. On the other hand, after defecation and cleaning of the anal area, the control panel 5 can be used to control the opening end of the enema tube 26 to reach inside the anal canal or rectum, and liquid is injected into the user's rectum through the enema tube 26, thereby cleaning any remaining feces in the rectum or anal sinuses. Since enemas require a completely different pressure than rinsing (rinsing requires a higher water pressure than enemas), a special transfer container is needed for the enema tube 26 to adjust the enema pressure in order to ensure safety. To address this issue, this embodiment connects a third reservoir to the enema tube 26. This third reservoir serves as a transfer container, primarily used to regulate the pressure of the fluid within the enema tube 26 to protect the human intestines. An enema pump is installed on the third reservoir, providing power for the enema. Specifically, the pump pumps the liquid from the third reservoir into the enema tube 26. A pressure protector is installed on the pump to prevent excessive enema pressure from damaging the intestines. Furthermore, the third reservoir has an openable inlet for adding medication, allowing for local application. Even further, the third reservoir can be integrated with the first reservoir 29, sharing the same container to save space in terms of components and arrangement. Figure 10 and Figure 11 As shown, based on this, a connection control valve also needs to be installed on the first liquid reservoir 29 or the third liquid reservoir. The connection control valve controls whether the inside of the first liquid reservoir 29 or the third liquid reservoir is connected to the outside atmosphere. When the first liquid supply device on the first liquid reservoir 29 is working, the connection control valve opens to connect the inside of the first liquid reservoir 29 to the outside atmosphere; when the enema pump device is working, the connection control valve closes to isolate the inside of the first liquid reservoir 29 from the outside atmosphere.

[0074] Furthermore, the cleaning mechanism 01 of the present invention may also be equipped with a blower (not shown in the figure). The air outlet of the blower is located on the support platform 6 and / or the cleaning hood 7. The first cleaning nozzle 8 may also be connected to the blower as the air outlet of the blower. The blower is used to blow air onto the cleaned anal area or vulva to make the moisture evaporate more quickly. Furthermore, the blower is preferably equipped with a heating element to heat the air to be blown out, thereby blowing out warm air, improving comfort, and also making the moisture evaporate more quickly and shortening the drying time.

[0075] This invention also provides a smart toilet seat, such as... Figure 5 As shown, the smart toilet seat includes a toilet seat 2, a seat ring, a storage box 3, and a cleaning mechanism 01 of this invention, which is housed inside the storage box 3. When the cleaning mechanism 01 is not cleaning, the cleaning cover 7 is stored inside the storage box 3. When the cleaning mechanism 01 is cleaning, the cleaning cover 7 extends from inside the storage box 3 to the working position. The smart toilet seat also includes a control panel 5. The aforementioned smart toilet seat can be used to retrofit existing toilets, such as... Figure 5 and Figure 8 As shown, the smart toilet seat can be fixed to the toilet via the mounting plate 20, thereby converting the existing toilet into a new type of toilet with a cleaning mechanism 01. Figure 6 and Figure 8 As shown, since the modified new toilet includes the cleaning mechanism 01 of the present invention, it can obtain some or all of the functions of the cleaning mechanism 01 described above.

[0076] Furthermore, such as Figure 5 , Figure 6 and Figure 8 As shown, the raised seat 13 provides space for the position switching of the washing cover 7 in the cleaning mechanism 01. The raised seat 13 or the toilet also has a supporting accessory 19a to support some components of the cleaning mechanism 01, making the cleaning mechanism 01 more stable. Figure 5 As shown, it is easy to understand that the raised seat ring 13 increases the user's height. To prevent the user's feet from dangling when sitting on the toilet, the invention also includes a footrest 16. By stepping on the footrest 16, the user can more easily sit on the toilet. Additionally, the footrest 16 can be used to elevate the user's feet while using the toilet, improving comfort. Furthermore, a handle 17 can be provided on the footrest 16, allowing for easy movement of the footrest 16.

[0077] The present invention also provides a toilet with the cleaning mechanism 01 described above, see reference. Figure 1 and Figure 5The two smart toilets provided include a toilet body 1, a toilet seat 2, a storage box 3, and a cleaning mechanism 01 of the present invention, which is housed inside the storage box 3. The toilet also includes a control panel 5. Since the above-mentioned toilets include the cleaning mechanism 01 of the present invention, users can experience some or all of the functions of the cleaning mechanism 01 described above. Figure 1 , Figure 2 The first type of smart toilet shown has a second storage box 3b at the rear. The top cover 3c of the second storage box 3b can be opened. The second storage box 3b is mainly used to store the displacement drive mechanism 02; as shown Figure 5 As shown, the second type of smart toilet has a foot pad 16 and a handrail 17. A storage box 18 can also be set at the back of the second type of smart toilet. The storage box 18 is used to store items such as a washing cover 7. Before use, the user can take out their own washing cover 7 from the storage box 18 and replace it, thereby avoiding cross-infection.
