Description

Technical Field

[0001] The present invention relates to the technical field of bathroom equipment, and in particular to a smart toilet cover and a smart toilet using the smart toilet cover. Background Art

[0002] A toilet is also called a toilet. As a commonly used sanitary ware, toilets are mainly divided into two types: ordinary toilets and smart toilets. Compared with traditional toilets, smart toilets have at least one of the following functions: automatic flushing, buttocks cleaning, automatic lid opening, automatic cover changing, seat ring insulation, warm air drying, automatic deodorization, silent seating, etc. The above functions can be controlled by button panels, remote control devices, automatic sensors, etc., so that people can have a comfortable toilet experience. Therefore, smart toilets are becoming more and more popular.

[0003] At present, smart toilets mainly realize the buttocks cleaning function and warm air drying function of smart toilets by setting a spray cleaning component and a dryer. The Chinese invention patent application with application number CN202010901732.3 (application publication number CN112196047A) discloses an integrated smart toilet, including a toilet body with a flushing cavity inside, a spray gun is provided on the toilet body, and the end of the spray gun close to the flushing cavity can inject water into the flushing cavity, and also includes a drying component for blowing air into the flushing cavity, and the drying component is arranged on the toilet body and located below the spray gun. The smart toilet sets the drying component in the middle of the toilet body and directly below the spray gun, so that the drying device can be aimed at the human buttocks, thereby improving the drying effect. However, during the use of the spray gun, especially when the spray gun is self-cleaning the nozzle, some of the water sprayed from the spray gun drips due to gravity. This part of water can easily enter the dryer from the air outlet, causing the dryer circuit to short-circuit and be damaged, affecting the normal use of the smart toilet.

[0004] At the same time, there is also a smart toilet cover for replacing ordinary toilet covers. After the user removes the toilet cover of the existing toilet and installs the smart toilet cover, the user can obtain the functions of the smart toilet, such as buttocks cleaning, seat heating, warm water washing, warm air drying, automatic deodorization, etc. Whether it has one or more functions depends on the functional positioning of the product. Compared with the aforementioned integrated smart toilet, it is cheaper to replace the smart toilet cover on the traditional toilet, so further improvement is needed. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a smart toilet cover that is not easily damaged by water in the dryer in view of the current status of the prior art. Compared with an integrated smart toilet, the cost of replacing a traditional toilet with the smart toilet cover is lower.

[0006] The second technical problem to be solved by the present invention is to provide a smart toilet whose dryer is not easily damaged by water ingress, in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: an intelligent toilet cover, comprising a base for connecting to a toilet body, the base having an inner cavity; a seat ring, the rear side of which is rotatably connected to the base; characterized in that: it also includes a spray gun installed in the inner cavity for spraying water toward the middle of the seat ring; a dryer installed outside the base and located below the spray gun.

[0008] In order to facilitate the installation of the spray gun and the dryer, the base includes a bottom plate and an upper cover covering the bottom plate, and the bottom plate and the upper cover together form an inner cavity; the spray gun is installed above the bottom plate, and the dryer is installed below the bottom plate.

[0009] In a further design, the front end of the spray gun has a water spray port, the bottom plate is recessed downward to form a guide groove located below the water spray port, the bottom wall of the guide groove gradually tilts downward from the back to the front to guide water to the front of the guide groove, and the front of the guide groove is provided with two water drop holes at intervals, the two water drop holes are respectively located on the left and right sides of the dryer, and can make water fall into the toilet bowl of the toilet body. The design of the guide groove can make the water dripping from the water spray port be guided by the bottom wall of the guide groove and flow obliquely downward to the front of the guide groove, avoid the air outlet of the dryer and flow out from the water drop holes located on the left and right sides of the dryer, preventing the water dripping from the water spray port from entering the dryer, thereby making the dryer less likely to be damaged by water.

[0010] It is further designed that the front side of the dryer has an air outlet, and a self-weight baffle for opening and closing the air outlet is provided at the air outlet, and the lower side of the self-weight baffle is hinged at the air outlet, and when the wind force of the dryer drives the self-weight baffle to open the air outlet, the self-weight baffle is in an upward tilted state, and when the dryer is closed, the self-weight baffle will seal the air outlet under the action of its own gravity. The design of the self-weight baffle can not only prevent the water sprayed from the spray gun from entering the dryer, but also prevent the excrement from falling or the sewage from splashing into the dryer when flushing the toilet, which can make the dryer less prone to damage, and the lower side of the self-weight baffle is hinged at the air outlet, which can guide the air outlet direction of the dryer to tilt upward and directly aim at the user's buttocks, instead of drying the user's buttocks by diffusing into the toilet bowl to increase the overall temperature of the toilet bowl, so that the warm air is more concentrated, the drying efficiency is higher, and the heat loss is less.

[0011] The technical solution adopted by the present invention to solve the second technical problem is: a smart toilet, including a toilet body, characterized in that: the toilet body is connected to the above-mentioned smart toilet cover, the rear part of the toilet body is downwardly provided with a recessed area connected to the outside, and the dryer is located in the recessed area. By providing a recessed area on the toilet body so that the dryer can be accommodated therein, the internal space of the toilet body can be more effectively utilized, the height of the smart toilet can be reduced, the rear part of the smart toilet is not too high compared to the front part, and the smart toilet can be made more beautiful as a whole.

[0012] Further design, the front part of the toilet body has a toilet bowl, and the bottom of the toilet bowl is provided with a sewage pipe; it also includes a water tank whose water inflow is controlled by an inlet valve, the water tank is connected to the toilet bowl through a flushing waterway, and the upper part of the water tank is also provided with an overflow pipe connected to the sewage pipe, and a first one-way valve is provided in the overflow pipe. The design of the water tank can prevent the flushing water pressure of the smart toilet from being affected by the living floor, ensure the flushing pressure of the smart toilet, and make the smart toilet flush more cleanly; the inlet valve is usually an electric control valve. When the inlet valve is damaged and cannot normally control whether the water tank is filled with water, the overflow pipe is designed to guide the excess water in the water tank into the sewage pipe, thereby preventing the water in the water tank from entering the base and damaging the circuit components; the design of the first one-way valve can prevent the sewage in the toilet bowl from backflowing into the water tank when the toilet is blocked. The water tank can be integrated with the toilet body, or it can be set separately from the toilet body; the position of the water tank can be set behind the toilet bowl, or it can be set above the rear of the toilet body.

[0013] Further design, the first one-way valve includes a mounting tube sealed and plugged into the overflow pipe, a mounting frame clamped in the mounting tube, a valve port is provided in the mounting tube, a through hole is provided on the mounting frame, a valve plug for opening or closing the valve port can be axially slidably penetrated in the through hole, a sealing ring which seals with the inner wall of the mounting tube is clamped on the valve plug, and a spring which is used to make the valve plug always have an upward movement tendency is also constrained between the mounting frame and the valve plug; the distance between the inlet of the overflow pipe and the top of the water tank is 30 to 50 mm; the inner diameter of the overflow pipe is 15 to 45 mm; the valve port is higher than the inlet of the S-bend pipe, and the distance between the valve port and the inlet of the overflow pipe is 60 to 120 mm; the opening pressure of the spring is 1 to 3 KPA. The installation of the valve plug is realized by the mounting tube, and it is more convenient to control the water pressure on the valve plug. The relevant parameter settings of each component can make the first one-way valve better in preventing sewage backflow.

[0014] In order to facilitate flushing of the toilet, the flushing water circuit includes a water outlet valve for controlling whether the water tank is flushed or not, and an annular tube connected to the water outlet valve and arranged on the upper part of the toilet body, the annular tube includes an annular portion and a connecting portion for connecting the water outlet valve and the annular portion, the annular portion is arranged on the top of the toilet bowl, and the annular portion is provided with a plurality of flushing holes aligned with the inlet of the sewage pipe at intervals, the connecting portion is provided with a water inlet connected to the water outlet valve, and the recessed area is located in the connecting portion. The relative positional relationship between the connecting portion and the recessed area of ​​the annular tube can facilitate the reasonable arrangement of the annular tube on the toilet body.

[0015] When the user uses a smart toilet in dim light or at night, the user needs to turn on the bathroom lighting to see the specific location and use of the smart toilet. In order to enable the user to use the smart toilet in a dark environment without turning on the bathroom lighting, a sensor is provided on the toilet body and / or the smart toilet cover, and a controller is provided in the base.
