Description

Technical Field

[0001] This invention belongs to the field of toilet technology, and relates to a toilet seat and a smart toilet. Background Technology

[0002] Smart toilets include flushing and drying functions. The flushing nozzle assembly and the drying assembly are fixed in the toilet seat. Currently, the toilet seat has a baffle plate at the front of the flushing nozzle assembly and the drying assembly. The baffle plate has openings that are aligned with the flushing nozzle assembly and the drying assembly, respectively. A sealing cover is rotated on the opening. When not in use, the sealing cover closes the opening. When in use, the sealing cover can be opened to realize the flushing or drying function.

[0003] Existing patents include a smart toilet vent structure for improving drying effect disclosed in Chinese patent documents [application number 202220159839X], an improved smart toilet [application number 201921665980], and a compact smart toilet seat [application number 2019204467406]. In these patents, the baffle is integrally formed on the toilet back cover, and the sealing cap is rotatably connected to the opening of the baffle. After the toilet back cover is installed with the toilet body, only the outer side of the baffle and the outer side of the sealing cap are exposed on the outside.

[0004] In actual use, urine splashing and water spray from the flushing nozzle will wet and soil the toilet seat cover and the toilet lid. In the humid environment inside the toilet, bacteria will grow on the inside and outside of the toilet seat cover and the gaps between the toilet seat cover and the toilet lid, which will contaminate the flushing nozzle and cause the hot air to dry to carry bacteria and odors. Currently, routine cleaning of the toilet seat cover and lid only allows for wiping the outer surfaces of these surfaces. While the lid can be manually rotated for cleaning, limitations in operating space and opening angle prevent complete cleaning, especially of the gap between the lid and cover. Cleaning the inside of the cover requires removing the entire toilet seat from the toilet body, which is difficult for ordinary users due to wiring and water pipe constraints. Cleaning the bidet nozzle requires activating the toilet's cleaning mode and then immediately disconnecting the power after the nozzle extends. Similarly, cleaning the drying unit's air outlet requires removing the entire toilet seat from the toilet body. Therefore, the current flushing and drying functions of smart toilets pose hygiene and safety risks, and ordinary users cannot easily achieve comprehensive disinfection and cleaning to address these risks through simple operations. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a toilet seat cover. The technical problem solved by this invention is to enable the entire flushing and drying baffles to be detachable and washable.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A toilet seat cover includes a seat cover shell, characterized in that the front end of the seat cover shell is provided with a mounting part, and the mounting part has an opening communicating with the inner cavity of the seat cover shell; the toilet seat cover also includes a cover, the cover is detachably connected to the mounting part, and a flushing cover and a drying cover are rotatably connected on the cover directly in front of the opening.

[0008] After the toilet seat cover, flushing baffle, and drying baffle become contaminated, the cover can be removed. The removed cover and its flushing and drying baffles can be thoroughly cleaned, and the exposed mounting parts can also be thoroughly cleaned. This simple operation allows for comprehensive disinfection and cleaning of the flushing and drying areas of the toilet seat, ensuring the hygiene and safety of the smart toilet's flushing and drying functions.

[0009] In the aforementioned toilet seat cover, a magnet is fixed to the inner side of the cover, and a magnet is fixed to the mounting part. When the cover is connected to the mounting part, magnets one and two adhere and attract each other. This magnetic attraction allows the cover to be detachably connected to the mounting part, making disassembly and installation convenient.

[0010] In the aforementioned toilet seat cover, the inner side of the cover is provided with a positioning cylinder, a magnet is fixed inside the positioning cylinder, a mounting part is provided with a positioning protrusion, and a magnet is fixed to the end of the positioning protrusion. When the cover is connected to the mounting part, the positioning protrusion is inserted into the positioning cylinder, and magnets one and two are attracted to each other. This structure improves the stability of the cover.

[0011] In another scenario, in the toilet seat described above, the cover is connected to the mounting part via a snap-fit ​​assembly. This snap-fit ​​assembly allows the cover to be detachably connected to the mounting part, facilitating easy installation and removal.

[0012] In the aforementioned toilet seat cover, a receiving space is formed between the cover and the mounting part. During use, splashed liquid and water remaining on the flush nozzle will enter this receiving space, preventing it from entering the interior of the seat cover.

[0013] In the aforementioned toilet seat cover, a positioning protrusion is provided near the edge of the mounting portion. The positioning protrusion includes an upper protrusion segment and side protrusion segments at both ends of the upper protrusion segment. When the cover is attached to the mounting portion, the inner side of the cover's sidewall fits against the positioning protrusion. The positioning protrusion ensures a more secure connection when the cover is attached.

[0014] In the aforementioned toilet seat cover, the opening includes a flushing opening and a drying opening, and the positioning ridge also includes a lower convex section located below the drying opening. The lower convex section engages with the side panel of the cover to prevent liquid from flowing from below the drying opening to the drying opening location.

[0015] In the aforementioned toilet seat cover, two water-retaining plates are provided on the inner side of the cover. These plates are located on both sides of the flushing cover, and their inner edges are abutted against the mounting portion when the cover is attached to it. The two water-retaining plates separate the accommodating space, preventing water from the flushing nozzle from flowing onto the drying cover and thus avoiding contamination of the drying area.

[0016] In the aforementioned toilet seat cover, a drain notch is provided at the lower edge of the side panel of the cover, aligned with the flushing baffle. Water from the flushing nozzle can flow directly out through the drain notch, reducing bacterial growth and decreasing the frequency of disinfection and cleaning.

[0017] In the aforementioned toilet seat cover, the upper or lower side of the cover is connected to the mounting part via a hinge. The cover is detachable by rotating the hinge, allowing for cleaning of its interior and the mounting part when opened.

[0018] The purpose of this invention is to address the aforementioned problems in existing technologies and to propose an intelligent toilet. The technical problem solved by this invention is to achieve hygienic and safe washing and drying.

[0019] A smart toilet, characterized in that it includes a toilet body and a toilet cover fixed to the rear of the toilet body, wherein a flushing nozzle assembly and a drying assembly are installed inside the toilet cover, the flushing nozzle assembly includes a retractable flushing nozzle, wherein when the flushing nozzle is in the retracted state, the head of the flushing nozzle is located inside the flushing baffle, and the drying assembly includes a drying fan, wherein the air outlet of the drying fan is directly opposite the drying baffle.

[0020] After opening the cover, the cleaning nozzle head and the air outlet of the drying fan are exposed, allowing for direct disinfection and cleaning of these components. This simple operation enables comprehensive disinfection and cleaning of the cleaning nozzle head and the air outlet of the drying fan, ensuring the hygiene and safety of the smart toilet's flushing and drying functions.

[0021] In the aforementioned smart toilet, a receiving groove is provided in the middle of the toilet body, and the cover is located in the receiving groove.

[0022] Compared with existing technologies, this smart toilet has the advantage of achieving comprehensive disinfection and cleaning of the washing and drying areas through simple operation, thus ensuring the hygiene and safety of the flushing and drying functions. Attached Figure Description
