Description

Cleaning utensils, cleaning units, toilets and smart toilet seats Technical Field

[0001] The present application relates to the field of bathroom equipment, and specifically discloses a female-specific cleaning appliance and a cleaning unit. The present application also discloses a toilet and an intelligent toilet seat using the cleaning unit. Background Art

[0002] Existing smart toilets are equipped with a cleaning device for cleaning the anus and / or vulva. The cleaning device includes a water outlet pipe that sprays water to flush the anus and / or vulva. However, because the outlet of the water outlet pipe is a certain distance from the user's anus and vulva, the outlet is often located below and behind the user. The liquid column formed by the cleaning liquid sprays from the rear and below to the front and above, and the liquid column has a high flow rate. The cleaning liquid has a high flow rate, and the cleaning liquid splashes and flows over a large area of ​​the user's body. In addition, the flushing area of ​​the water outlet of the existing toilet cleaning device is relatively fixed. However, due to individual differences in users or the same user's inconsistent sitting posture from time to time, the flushing may not be properly aimed at the user's anus and / or vulva, easily wetting and contaminating parts of the body outside the target cleaning area.

[0003] Summary of the Invention

[0004] In order to solve one of the technical problems existing in the prior art, the present application provides a cleaning device specifically for women, and a cleaning unit based on the cleaning device, which is used to clean the female vulva without wetting or contaminating parts of the human body other than the target cleaning area.

[0005] The present application also provides a toilet and an intelligent toilet seat using the above-mentioned cleaning unit.

[0006] According to a first aspect of an embodiment of the present invention, a cleaning device is used for cleaning the female vulva, comprising a first cleaning cover having an upper opening, a sewage outlet provided at a lower portion of the first cleaning cover, the upper opening of the first cleaning cover being in communication with the sewage outlet at the lower portion of the cleaning cover, a cleaning nozzle provided within the first cleaning cover, the cleaning nozzle being connected to a liquid supply pipe for spraying liquid for cleaning, and the cleaning nozzle cleaning the female vulva from inside and / or outside the vaginal vestibule;

[0007] When the cleaning nozzle cleans the vulva from the inside of the vaginal vestibule, the cleaning nozzle includes a first cleaning nozzle, which is configured to match the shape of the female vaginal vestibule so as to enter between the two labia minora for cleaning. When the upper opening of the first cleaning cover is located at the vulva, the first cleaning nozzle extends into the vaginal vestibule area to clean the vulva from the inside of the vaginal vestibule.

[0008] When the cleaning nozzle cleans the vulva from outside the vaginal vestibule, the cleaning nozzle includes a second cleaning nozzle. When the upper opening of the first cleaning cover is located at the vulva, the second cleaning nozzle is located outside the vaginal vestibule area, and the second cleaning nozzle cleans the vulva from outside the vaginal vestibule.

[0009] The cleaning device according to the first embodiment of the present invention has at least the following beneficial effects: the cleaning device of the present application includes a first cleaning cover and a cleaning nozzle. When the opening of the first cleaning cover is placed on the user's vulva on the toilet seat, the cleaning nozzle on the first cleaning cover performs a close flushing and cleaning of the vulva. The first cleaning cover can prevent the cleaning liquid from leaking out of the opening of the first cleaning cover to the outside of the first cleaning cover, and limit the wetting range to the range covered by the first cleaning cover, thereby preventing the cleaning liquid from wetting and contaminating the human body parts outside the first cleaning cover during flushing; the cleaning nozzle cleans the user's vulva from the inside of the user's vaginal vestibule or / and from the outside of the vaginal vestibule, and can perform zoned cleaning on different parts of the female vulva.

[0010] In addition, since a cleaning tool is used for close cleaning, and the first cleaning cover can prevent the cleaning liquid from wetting and contaminating the human body parts outside the first cleaning cover during flushing, the liquid outlet of the first cleaning nozzle can use a larger interception area to form a thicker liquid column for cleaning, making the cleaning more thorough, and the flow rate of the cleaning liquid column can be appropriately reduced to reduce the discomfort during flushing of the cleaning liquid column.

[0011] According to the cleaning device described in the embodiment of the first aspect of the present invention, when the cleaning nozzle includes the first cleaning nozzle and the second cleaning nozzle at the same time, that is, when the cleaning nozzle cleans the user's vulva from inside and outside the vaginal vestibule of the user, the height of the first cleaning nozzle is higher than the height of the second cleaning nozzle, and the second cleaning nozzle and the first cleaning nozzle are connected to the same liquid supply pipe or to different liquid supply pipes.

When the upper opening of the first cleaning cover is located at the vulva position, the third cleaning nozzle is used to clean the female labia majora and the area around the labia majora.

[0013] According to the cleaning device described in the embodiment of the first aspect of the present invention, when the cleaning nozzle includes the first cleaning nozzle, a buffer structure in the up and down directions is arranged below the first cleaning nozzle, and the buffer structure can be extended and retracted up and down. When the first cleaning nozzle enters the user's vaginal vestibule area, the height of the first cleaning nozzle is adjusted by the up and down extension and retraction of the buffer structure, so that the height of the first cleaning nozzle can match the height of the user's vaginal vestibule, and at the same time, the collision force between the first cleaning nozzle and the vaginal vestibule area can be reduced, thereby protecting the female body.

[0014] According to the cleaning device described in the embodiment of the first aspect of the present invention, when the cleaning nozzle includes the first cleaning nozzle, a depth limiter is provided on the outer periphery of the first cleaning nozzle. When the upper opening of the first cleaning cover is located at the user's vulva, when the first cleaning nozzle is extended into the user's vaginal vestibule area, the depth limiter is stuck on the outside of the user's labia minora, which can prevent the first cleaning nozzle from entering the vaginal vestibule area too deeply, so as to prevent the first cleaning nozzle from extending into the vagina; when the depth limiter is stuck on the outside of the labia minora, the top end of the first cleaning nozzle can also be prevented from contacting the human body, thereby avoiding contact and damage to the vaginal vestibule area. The top end of the first cleaning nozzle not contacting the human body can also avoid leaving a blind spot for cleaning; and a gap is left between the top of the first cleaning nozzle and the top of the vaginal vestibule area, which can prevent the user's body from blocking the liquid outlet of the first cleaning nozzle, so as to achieve a more stable liquid outlet speed of the first cleaning nozzle.

[0052] The present invention will be further described below with reference to several embodiments in conjunction with Figures 1 to 11 .

[0053] As shown in Figures 1, 2, and 6 to 11, the present invention provides various embodiments of cleaning devices 01. It should be noted that all embodiments of cleaning devices 01 provided herein can be used to clean the female vulva. The female vulva referred to herein corresponds to the female perineum in a broad sense.

[0054] Specifically, the cleaning device 01 includes a first cleaning cover 1 with an upper opening. A first sewage outlet 1a is provided at the lower portion of the first cleaning cover 1. The upper opening of the first cleaning cover 1 is connected to the first sewage outlet 1a. A cleaning nozzle 2 is provided within the first cleaning cover 1. The cleaning nozzle 2 is connected to a liquid supply pipe for spraying liquid for cleaning. The cleaning nozzle 2 cleans the user's vulva from the inside of the user's vaginal vestibule, or the cleaning nozzle 2 cleans the user's vulva from the outside of the user's vaginal vestibule, or the cleaning nozzle 2 cleans the user's vulva from both the inside and outside of the user's vaginal vestibule. When the cleaning nozzle 2 cleans the user's vulva from inside the user's vaginal vestibule, the cleaning nozzle 2 includes a first cleaning nozzle 2a. The first cleaning nozzle 2a is configured to match the shape of the female vaginal vestibule so as to enter between the two labia minora for cleaning. When the upper opening of the first cleaning cover 1 is positioned at the user's vulva, the first cleaning nozzle 2a extends into the user's vaginal vestibule and cleans the vulva from inside the vaginal vestibule. When the cleaning nozzle 2 cleans the user's vulva from outside the vaginal vestibule, the cleaning nozzle 2 includes a second cleaning nozzle 2b. When the upper opening of the first cleaning cover 1 is positioned at the user's vulva, the second cleaning nozzle 2b is located outside the user's vaginal vestibule and cleans the vulva from outside the vaginal vestibule. When the cleaning nozzle 2 includes the first cleaning nozzle 2a and the second cleaning nozzle 2b at the same time, that is, when the cleaning nozzle 2 cleans the user's vulva from the inside and outside of the user's vaginal vestibule, the height of the first cleaning nozzle 2a is higher than the height of the second cleaning nozzle 2b, and the second cleaning nozzle 2b is distributed around the first cleaning nozzle 2a. The second cleaning nozzle 2b and the first cleaning nozzle 2a are connected to the same liquid supply pipe or to different liquid supply pipes. When the first cleaning nozzle 2a and the second cleaning nozzle 2b are set at the same time, the first cleaning nozzle 2a is used to clean the inside of the user's vaginal vestibule, and the second cleaning nozzle 2b is used to clean the outside of the user's vaginal vestibule area. Depending on the different ways of connecting the liquid supply pipes, the first cleaning nozzle 2a and the second cleaning nozzle 2b can use a common liquid supply or a separate liquid supply; when the first cleaning nozzle 2a and the second cleaning nozzle 2b are respectively connected to different liquid supply pipes, the user can choose to open the liquid supply of different cleaning nozzles 2 to achieve zoned cleaning. The user can choose different areas for cleaning. The user can choose the size of the cleaning range according to the size of the contamination range of the vulva, so as to achieve a more accurate cleaning range and avoid wetting too large an area.

[0055] Based on the above structure, a third cleaning nozzle 2c may also be provided within the first cleaning cover 1. The third cleaning nozzle 2c is located outside the second cleaning nozzle 2b. When the upper opening of the first cleaning cover 1 is positioned at the vulva, the third cleaning nozzle 2c is used to clean the labia majora and the surrounding areas. The provision of the third cleaning nozzle 2c to spray liquid on the labia majora and the surrounding areas of the labia majora can expand the cleaning range of the cleaning nozzle 2. Furthermore, the third cleaning nozzle 2c can be connected to the same liquid supply pipe as the first cleaning nozzle 2a and the second cleaning nozzle 2b to achieve liquid supply and cleaning together; the third cleaning nozzle 2c can also be connected to different liquid supply pipes with the first cleaning nozzle 2a and the second cleaning nozzle 2b. In addition, the third cleaning nozzle 2c can also be connected to different liquid supply pipes with the first cleaning nozzle 2a, and the third cleaning nozzle 2c and the second cleaning nozzle 2b are connected to the same liquid supply pipe, and the first cleaning nozzle 2a and the second cleaning nozzle 2b can be connected to different liquid supply pipes. By separately controlling the liquid supply pipes, the user can choose to open different cleaning nozzles 2 to achieve cleaning of specific areas.

[0056] Furthermore, the first cleaning cover 1 is a cover structure with an upper opening, an opening is provided on the upper portion of the first cleaning cover 1, and a first sewage outlet 1a is provided on the lower portion, and the opening on the upper portion of the first cleaning cover 1 is communicated with the first sewage outlet 1a. The first cleaning cover 1 can be made of one or more materials selected from metal, ceramic, glass and plastic, wherein ceramic material is most preferred because the surface of the ceramic material becomes smooth after glazing, and dirt is not easily adhered, which is convenient for cleaning the surface of the first cleaning cover 1. In addition, a coating can also be provided on the surface of the first cleaning cover 1, such as using a wear-resistant oleophobic and hydrophobic coating on the surface of the first cleaning cover 1. The coating makes the surface of the first cleaning cover 1 smooth, and liquids, cleaning agents, excrement, dirt, etc. are not easily adhered to the surface of the first cleaning cover 1, and are easily rinsed clean, making the surface of the first cleaning cover 1 easy to clean and self-cleaning. The cross section of the first cleaning cover 1 can be a regular shape such as a rounded rectangle, a circle, an ellipse, etc., with a simple structure, easy to make, and conducive to reducing costs. The curve of the upper opening of the first cleaning cover 1 can also be set to an ergonomic curve that conforms to the position of the human vulva, so that the upper opening of the first cleaning cover 1 can fit more closely with the part of the human body it contacts, which is more effective in blocking the cleaning liquid and increases the comfort of use.

[0057] Furthermore, a buffer structure 21 in the up and down directions is provided below the first cleaning nozzle 2a. The buffer structure 21 includes an upper telescopic tube, a lower telescopic tube, a spring, and a bellows. The upper end of the upper telescopic tube is connected to the first cleaning nozzle 2a, and the lower end of the lower telescopic tube is connected to the first cleaning cover 1. The upper telescopic tube can be slid up and down and is sleeved on the lower telescopic tube. There is a longitudinal slider protruding outward on the outer wall of the upper telescopic tube, and there is a slot on the lower telescopic tube that cooperates with the longitudinal slider of the upper telescopic tube. The longitudinal slider on the outer wall of the upper telescopic tube and the slot on the lower telescopic tube cooperate to realize that the upper telescopic tube can be slid up and down and is sleeved on the lower telescopic tube, and the upper telescopic tube cannot rotate along its longitudinal axis. The spring is sleeved on the upper telescopic tube and the lower telescopic tube, one end of the spring is stuck on the upper telescopic tube, and the other end of the spring is stuck on the lower telescopic tube. The bellows is sleeved on the outside of the upper telescopic tube, the lower telescopic tube and the spring, the upper end of the bellows is sealed and connected to the upper end of the upper telescopic tube, and the lower end of the bellows is sealed and connected to the lower end of the lower telescopic tube. The bellows can seal the buffer structure 21 to prevent the buffer structure 21 from leaking. When a downward force is applied to the first cleaning nozzle 2a, the upper telescopic tube slides downward, the spring and the bellows are compressed, and the buffer structure 21 shortens; when the downward force on the first cleaning nozzle 2a disappears, the spring and the bellows are extended, and the spring drives the upper telescopic tube to slide upward to reset. The buffer structure 21 can be extended and retracted up and down. When the first cleaning nozzle 2a enters the user's vaginal vestibule area, the height of the first cleaning nozzle 2a is adjusted by the up and down extension of the buffer structure 21, so that the height of the first cleaning nozzle 2a can match the height of the user's vaginal vestibule. At the same time, the collision force between the first cleaning nozzle 2a and the vaginal vestibule area can be reduced to protect the female body. It should be noted that the buffer structure 21 can also be made of other structures and components to achieve upward and downward extension. Those skilled in the art can select appropriate structures and components to make the buffer structure 21 according to actual conditions.

[0058] Furthermore, when the cleaning nozzle 2 cleans the user's vulva from the inside of the user's vaginal vestibule, or when the cleaning nozzle 2 cleans the user's vulva from both the inside and outside of the user's vaginal vestibule, a depth stopper 20 is provided on the first cleaning nozzle 2a or the second cleaning nozzle 2b. When the upper opening of the first cleaning cover 1 is provided at the user's vulva, the first cleaning nozzle 2a extends into the user's vaginal vestibule area, and the depth stopper 20 is stuck on the outside of the user's labia minora, thereby preventing the first cleaning nozzle 2a from entering the vaginal vestibule area. The depth of the first cleaning nozzle 2a is too deep to prevent the first cleaning nozzle 2a from extending into the vagina; when the depth limiter 20 is stuck on the outside of the labia minora, the top of the first cleaning nozzle 2a will not touch the human body, avoiding contact and damage to the vaginal vestibule area. The top of the first cleaning nozzle 2a not touching the human body can also avoid leaving a cleaning blind spot; the depth limiter 20 is stuck on the outside of the labia minora to leave a gap between the top of the first cleaning nozzle 2a and the top of the vaginal vestibule area, so as to avoid the user's body blocking the liquid outlet of the first cleaning nozzle 2a, so as to achieve a more stable liquid outlet speed of the first cleaning nozzle 2a.

[0059] It should be understood that the cleaning device 01 also includes a second cleaning cover 3 for covering the anus. The second cleaning cover 3 is provided with an opening at the top, and a second sewage outlet 3a is provided at the bottom of the second cleaning cover 3. The opening at the top of the second cleaning cover 3 is connected to the second sewage outlet 3a. A fourth cleaning nozzle 4 is provided in the second cleaning cover 3. When the opening at the top of the second cleaning cover 3 is located at the anus, the fourth cleaning nozzle 4 rinses and cleans the anus area. The arrangement of the second cleaning cover 3 and the fourth cleaning nozzle 4 can be used to clean the anus area.

[0077] In some embodiments of the present application, the cleaning nozzle 2 and the fourth cleaning nozzle 4 of the cleaning device 01 are connected to tap water via a liquid supply pipe, and tap water is used for rinsing and cleaning. Referring to Figures 3 and 4, in the embodiments shown in Figures 3 and 4, the cleaning unit 02 may also include a liquid storage mechanism 11, the liquid storage mechanism 11 includes a plurality of liquid reservoirs 11a, the interior of the liquid reservoirs 11a is respectively used to hold cleaning liquids added with cleaning agents or specific drugs, the liquid storage mechanism 11 is provided with a cleaning liquid output pipe, the cleaning liquid output pipe is connected to a pipeline distributor, the cleaning liquid in the liquid reservoir 11a is transported to the pipeline distributor through the cleaning liquid output pipe, the pipeline distributor is used for selecting and switching pipeline connections; the pipeline distributor is provided with a plurality of liquid supply pipes connected to the cleaning nozzles on the cleaning device 01. The pipes on the cleaning device 01 and the pipes on the support platform 7 are connected by a quick connector 12. The liquid supply pipes are respectively connected to the cleaning nozzle 2 and the fourth cleaning nozzle 4 of the cleaning device 01. The cleaning liquid passes through the pipe distributor and is finally provided to the cleaning nozzle 2 or the fourth cleaning nozzle 4. The pipe distributor can control the liquid output of the cleaning nozzle 2 or the fourth cleaning nozzle 4.

[0078] In some embodiments of the present application, to facilitate cyclic cleaning, a liquid storage mechanism 11 is further provided in the cleaning unit 02. The liquid storage mechanism 11 may include a first liquid reservoir, a first liquid supply device, a second liquid reservoir, and a second liquid supply device. The first liquid reservoir is connected to the pipeline distributor via a first liquid supply pipe; the second liquid reservoir is connected to the pipeline distributor via a second liquid supply pipe.

[0079] The cleaning nozzle 2 and the fourth cleaning nozzle 4 are connected to the first liquid reservoir and the second liquid reservoir respectively. The first liquid reservoir can be divided into two chambers, one chamber can supply liquid to the cleaning nozzle 2, and the other chamber can supply liquid to the fourth cleaning nozzle 4; the first liquid reservoir can also be a single chamber. The second liquid reservoir can be divided into two chambers, one chamber can supply liquid to the cleaning nozzle 2, and the other chamber can supply liquid to the fourth cleaning nozzle 4; the second liquid reservoir can also be a single chamber. The first liquid supply device can pump the liquid in the first liquid reservoir into the cleaning nozzle 2 and / or the fourth cleaning nozzle 4. The second liquid supply device can pump the liquid in the second liquid reservoir into the cleaning nozzle 2 and / or the fourth cleaning nozzle 4.

[0080] Furthermore, the first liquid reservoir is provided with an openable inlet for adding liquid medicine, and the second liquid reservoir 30 is provided with detergent to achieve different usage effects. After the liquid medicine in the first liquid reservoir is pumped into the cleaning cover to be applied (the first cleaning cover 1 and / or the second cleaning cover 3) via the first liquid supply device, the circulating cleaning function of the corresponding cleaning cover to be applied is activated to achieve a circulating medicinal bath for the female user's anus and / or vulva. After the medicinal bath is completed, the cleaning nozzle 2 and the fourth cleaning nozzle 4 can be connected to a clean water source such as tap water or a water purifier to flush out the liquid medicine. The cleaning agent in the second liquid reservoir 30 is pumped into the second liquid supply pipe through the second liquid supply device. The second liquid supply pipe is also connected to a water source. The water and detergent are mixed in the second liquid supply pipe and then sent into the cleaning cover to be circulated (the first cleaning cover 1 and / or the second cleaning cover 3). The circulating cleaning function of the corresponding cleaning cover to be circulated is turned on to realize the circulating cleaning of the anus and / or vulva of the female user. After the washing is completed, the cleaning nozzle 2 and the fourth cleaning nozzle 4 are connected to the water source to flush out the detergent with water.

[0081] Furthermore, the cycle cleaning process is as follows:

[0082] In the first case, the circulation cleaning can be divided into two stages. The first stage is the circulation flushing of the detergent aqueous solution or the liquid medicine. The second stage is the water flushing. Taking the circulation cleaning of the first cleaning cover 1 as an example, when the circulation cleaning of the first stage is completed, the first sewage outlet 1a is opened, the first circulation outlet 1b is opened, and the first circulation drive mechanism operates until the cleaning liquid in the first circulation pipe and the first circulation drive mechanism is drained, and the first circulation drive mechanism stops operating. During the second stage of water cleaning, the first sewage outlet 1a is opened, the first circulation outlet 1b is also opened, and the water from the water source is sprayed through the cleaning nozzle 2 to flush the vulva. At the same time, the water from the water source flows in the reverse direction through the first circulation pipe. The first circulation drive mechanism drives the water flow in the reverse direction, and the water flows out through the first circulation outlet 1b. After the flushing is completed, the cleaning nozzle 2 stops spraying liquid, and the first circulation drive mechanism continues to operate until the water in the first circulation pipe and the first circulation drive mechanism is drained, the first circulation drive mechanism stops operating, and the first circulation outlet 1b is closed.

[0083] In addition, in the second case, the circulation cleaning of the first cleaning cover 1 can also include four stages: the first stage: the first sewage outlet 1a is opened and the first circulation outlet 1b is closed; water from the water source is sprayed through the cleaning nozzle 2 to clean the dirt (leucorrhea, menstruation, urine, dirt, secretions, etc.) adhered to the female vulva; the second stage: first, the first sewage outlet 1a is closed and the first circulation outlet 1b is opened, and then, the liquid medicine in the first liquid reservoir is pumped into the first cleaning cover 1 by the first liquid supply device, or the detergent and water in the second liquid reservoir are mixed and sent into the first cleaning cover 1; the third stage: the first circulation drive mechanism is operated to carry out local circulation flushing of the liquid medicine or detergent water solution, and the end of this stage , the first sewage outlet 1a is opened, the first circulation outlet 1b is opened, and the first circulation drive mechanism continues to operate until the cleaning liquid in the first circulation pipe and the first circulation drive mechanism is drained; the fourth stage: the first sewage outlet 1a is opened, the first circulation outlet 1b is opened, and the water from the water source is sprayed out through the cleaning nozzle 2 to rinse the vulva position and the inside of the first cleaning cover 1, and flows in the reverse direction through the first circulation pipe. The first circulation drive mechanism reversely drives the water to flow, and the water flows out through the first circulation outlet 1b. After the flushing is completed, the cleaning nozzle 2 stops spraying liquid, and the first circulation drive mechanism continues to operate until the water in the first circulation pipe and the first circulation drive mechanism is drained, the first circulation drive mechanism stops operating, and the first circulation outlet 1b is closed.

[0084] It is understood that the cyclic cleaning of the second cleaning cover 3 can also be carried out in either of the above two situations. The specific principles and processes refer to the principles and steps of the cyclic cleaning of the first cleaning cover 1. Among them, the cyclic cleaning of the second cleaning cover 3 can be carried out simultaneously with the cyclic cleaning of the first cleaning cover 1, or they can be carried out separately.

[0085] Furthermore, the cleaning unit 02 includes an enema tube, which is disposed on the support platform 7 or the cleaning device 01. The enema tube is located outside the first cleaning cover 1 and the second cleaning cover 3. In the embodiment provided in FIG3 , the enema tube is fixed to the second mounting bracket 6. On the one hand, the enema tube can be used before defecation. After the user controls the driving device via the control device to move the open end of the enema tube into the anal canal or rectum, the enema tube injects liquid into the user's large intestine through the anus, thereby helping constipated users to defecate smoothly. On the other hand, after completing defecation and cleaning the anal area, the user can control the driving device via the control device to move the open end of the enema tube into the anal canal or rectum, and use the enema tube to inject liquid into the user's rectum, thereby cleaning a small amount of feces that may remain in the rectum or anal sinus. Since enema requires a completely different pressure from flushing (the water pressure required for flushing is higher than that required for enema), in order to ensure safety, a special transfer container is required for the enema pipeline. An enema pump device is provided on the transfer container to provide enema pressure. The enema pump device provides power for the enema by pumping air into the transfer container. The transfer container can be integrated with the first liquid reservoir, and the two share the same container, that is, the transfer container can be the same container as the first liquid reservoir to save space for components and layout. On this basis, a communication control valve is also required on the first liquid reservoir to control whether the interior of the first liquid reservoir is connected to the external atmosphere. When the first liquid supply device on the first liquid reservoir is working, the communication control valve is opened to connect the interior of the first liquid reservoir with the external atmosphere; when the enema pump device is working, the communication control valve is closed to isolate the interior of the first liquid reservoir from the external atmosphere.

[0086] Furthermore, as a preferred solution, a heater can also be provided on the cleaning unit 02. The heater can be provided on at least one of the cleaning tool 01, the support platform 7, and the inside of the storage box 19. The heater is used to heat the first cleaning cover 1 and the second cleaning cover 3 so that they have a temperature close to that of the human body, thereby improving the comfort of the user when using the cleaning tool 01.

[0087] Furthermore, cleaning unit 02 includes a blower, the air outlet of which is disposed on support platform 7 and / or cleaning device 01. The blower is used to blow air over the vulva and anus after cleaning, accelerating the evaporation of moisture. Furthermore, the blower is preferably equipped with a heating element, which heats the air to be blown, producing warm air. This improves comfort, accelerates moisture evaporation, and shortens drying time.

[0088] The cleaning unit 02 of the present application includes a cleaning tool 01 and a displacement drive mechanism. The cleaning tool 01 has a storage position and a working position. The cleaning tool 01 is driven by the displacement drive mechanism to switch between the storage position and the working position. When the cleaning tool 01 is in the storage position, it does not affect the normal use of the toilet. When the cleaning tool 01 is in the working position, the opening of the first cleaning cover 1 covers the vulva of the user on the toilet, and the cleaning nozzle 2 in the first cleaning cover 1 performs close flushing and cleaning of the vulva. The first cleaning cover 1 can prevent the cleaning liquid from leaking from the opening of the first cleaning cover 1 to the outside of the first cleaning cover 1, and limit the wetting range to the range covered by the first cleaning cover 1, so as to avoid the cleaning liquid wetting and contaminating the area outside the first cleaning cover 1 during flushing. In addition, since the cleaning tool 01 is used for close cleaning, the liquid outlet of the first cleaning nozzle 2a can use a larger cross-flow area to form a thicker liquid column for cleaning, making the cleaning more thorough, and the flow rate of the cleaning liquid column can be appropriately reduced to reduce the discomfort during flushing of the cleaning liquid column.

[0089] As shown in Figures 4 and 5 , the third embodiment of the present application further provides a toilet, comprising a toilet body. In this embodiment, the toilet body is a toilet bowl 13, which is provided with a seat 14 and a toilet lid 15. The toilet body is also provided with the aforementioned cleaning unit 02 and a storage box 19. The cleaning unit 02 is disposed within the storage box 19, and an openable storage door 16 is provided in front of the storage box 19. When the cleaning device 01 is in the storage position, the cleaning unit 02 is entirely located within the storage box 19, and the storage door 16 is closed, preventing wastewater from the toilet bowl 13 from splashing into the storage box 19. When the cleaning device 01 is driven by the displacement drive mechanism to switch positions, the storage door 16 opens, and the drive device 8 is activated. Part of the drive device 8 and the entire cleaning device 01 pass through the storage door 16 and reach the toilet bowl 13. After the cleaning device 01 has been adjusted in position, it enters the operating position. The toilet of the present application includes a cleaning unit 02 according to the second embodiment of the present invention, which can be used by women to clean their vulva on the toilet. Normally, the cleaning device 01 is in a storage position, which does not affect the normal use of the toilet. When the cleaning device 01 is driven to the working position by the displacement drive mechanism, the first cleaning cover 1 in the cleaning device 01 is placed on the vulva of the user on the toilet. The cleaning nozzle 2 performs a close-range flushing and cleaning of the vulva, limiting the wetting range to the interior of the first cleaning cover 1. The liquid outlet of the cleaning nozzle 2 can use a larger interception area to form a thicker liquid column to clean the vulva, making the cleaning more thorough and reducing the flow rate of the cleaning liquid column, thereby reducing discomfort during flushing. The storage box 19 serves to store and protect the cleaning unit 02. At the same time, the provision of the storage box 19 can make the overall appearance of the toilet more concise.

[0090] Furthermore, an ultraviolet lamp or an ozone generator for disinfection is provided inside the storage box 19, which can disinfect the cleaning unit 02 stored inside the storage box 19 by irradiating ultraviolet light or releasing ozone.

[0091] In addition, the present application also provides a smart toilet seat (not shown in the figure), which is applied to a toilet. The smart toilet seat includes the above-mentioned cleaning unit 02 and a storage box 19, and the cleaning unit 02 is disposed in the storage box 19. The smart toilet seat provided by the present application includes the cleaning unit 02 of the second embodiment. The smart toilet seat provided by the present application can be used to modify an existing toilet. After the modification, the toilet has the cleaning unit 02 of the second embodiment of the present application. Women can use the cleaning unit 02 to clean their vulva on the modified toilet. Normally, the cleaning device 01 is located in the storage position and does not affect the normal use of the toilet. When the cleaning device 01 is driven to switch to the working position by the displacement drive mechanism, the first cleaning cover 1 in the cleaning device 01 is set on the vulva position of the user on the toilet, and the cleaning nozzle 2 performs close flushing and cleaning of the vulva position, limiting the wetting range to the inside covered by the first cleaning cover 1. The liquid outlet of the cleaning nozzle 2 can use a larger interception area to form a thicker liquid column to clean the vulva position, making the cleaning more thorough, and can reduce the flow rate of the cleaning liquid column, reducing the discomfort during flushing of the cleaning liquid column.
