Description

Technical Field

[0001] The invention relates to the technical field of toilets, in particular to a toilet with a switching detection mode. Background Art

[0002] Existing smart toilets with radar need to be turned on and off according to the status of the cover ring. Or the radar sends all scanning data to the main control board of the whole machine, which processes the radar scanning data, obtains the scanning results, and performs corresponding actions. When the radar module is turned off and on, the chip will have a restart process. The restart process takes a long time, which will make the radar react slower, and there will be a delay in judging the user's actions, which is not a good experience. Sending all data to the whole machine will increase the computing power of the whole machine and occupy the chip resources of the whole machine. For this reason, a simple and efficient radar working mode is provided to improve the experience. For this reason, we provide a toilet with a switching detection mode to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a toilet with a switch detection mode.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A toilet with a switchable detection mode comprises a toilet body, on which a seat ring and an upper cover are mounted, and also comprises an environmental sensor for detecting the state of the surrounding environment, a cover plate state sensor for detecting the open and closed states of the upper cover and the seat ring, and a main control board, wherein the main control board is used to connect signals with the environmental sensor and the cover plate state sensor and to control the operation of several functional components, wherein the environmental sensor has several detection modes, wherein the detection modes include a urination detection mode, and when the cover plate state sensor detects a signal indicating that the seat ring is open, the main control board controls the environmental state sensor to switch to the urination detection mode.

[0006] Preferably, the environmental status sensor is a radar sensor, an infrared sensor, a camera or a combination thereof.

[0007] Preferably, the cover plate status sensor comprises an upper cover status sensor for detecting an open or closed status of the upper cover and a seat ring status sensor for detecting an open or closed status of the seat ring.

[0008] Preferably, when the cover plate status sensor detects that the seat ring is closed and the upper cover is closed, the environmental status sensor switches to the first detection mode; when the cover plate status sensor detects that the seat ring is closed and the upper cover is opened, the environmental status sensor switches to the second detection mode.

[0009] Preferably, the signals detected by the environmental status sensor in the first detection mode are large-range human body signals and usage intention signals; the signals detected by the environmental status sensor in the second detection mode are small-range human body signals and large-range human body signals; the signals detected by the environmental status sensor in the urination detection mode are urination signals, small-range human body signals and large-range human body signals.

[0010] Preferably, in the urination detection mode, the environment detection sensor detects the urine column to determine whether there is a urination start signal and a urination end signal, and when the urination end signal is detected, the flushing component is started to flush, or, when the urination start signal is detected, the flushing component is started to flush after a preset time, or, when the urination end signal is detected and the small-range human body signal disappears, the flushing component is started to flush.

[0011] Preferably, the environmental sensor detects whether there is someone in the second preset area to determine whether there is a large-scale human body signal, and determines whether there is an intention to use signal by detecting the speed and stay time of the human body in the first preset area. The environmental sensor detects whether the human body makes a limb movement in the third preset area and determines it as a gesture signal. The environmental sensor determines whether there is a small-scale signal by detecting whether there is someone in a small area in the third preset area.

If there is a use intention signal, the upper cover is opened through the upper cover control component; if there is no use intention signal, the upper cover is not opened. If there is a large-scale signal, the various functional components of the toilet enter the standby state, and if there is no large-scale human signal, the smart toilet function enters hibernation; in the second detection mode, the environmental status sensor determines whether there is a small-scale human signal by detecting whether there is someone in the third preset area, and determines whether there is a gesture signal by whether someone makes a body movement; in the second detection mode, the gesture signal is detected on the basis of detecting the presence of a large-scale human signal, and if there is a gesture signal and a use intention signal, the seat is opened through the seat control component.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1 —3 shown in the embodiment:

[0025] A toilet with a switchable detection mode comprises a toilet body 1, on which a seat ring 2 and an upper cover 3 are mounted, and is characterized in that it also comprises an environmental sensor 4 for detecting the state of the surrounding environment, a cover plate state sensor for detecting the open and closed states of the upper cover 3 and the seat ring 2, and a main control board, wherein the main control board is used to connect signals with the environmental sensor 4 and the cover plate state sensor and to control the operation of several functional components, wherein the environmental sensor 4 has several detection modes, wherein the detection modes include a urination detection mode, and when the cover plate state sensor detects a signal that the seat ring 2 is open, the main control board controls the environmental state sensor to switch to the urination detection mode.

[0026] The environmental sensor 4 first detects the opening status of the seat ring 2 and the upper cover 3 through the cover status sensor, so as to facilitate the environmental sensor 4 to detect which detection mode to use, which can reduce the environmental sensor 4 to detect all modes, thereby reducing the increase in data leading to an increase in the amount of calculation of the whole chip and occupying more chip resources, reducing the delay in judging the user's actions, improving the overall fluency, and improving the user's experience.

[0027] The environmental status sensor 4 is a combination of one or more of a radar sensor, an infrared sensor, and a camera. The human body's movements are collected in real time through one or more of the radar sensor, the infrared sensor, and the camera, and the collected movement information and / or body information is transmitted to the main control board. The main control board analyzes the information and controls each functional component (such as a seat control component, an upper cover control component, a seat heating component, a voice component, a human body cleaning component, a drying component, a flushing component, etc.) to be turned on or off. The environmental sensor 4 is installed on the toilet body 1 according to different types or different usage requirements, or is installed on the side wall of the space where the toilet body 1 is installed (such as a toilet) to collect and scan the human body's movements. Figure 1 The position where the radar sensor 4 is installed is shown, and the radar sensor can also be installed in other positions as needed.

[0028] The cover plate status sensor includes an upper cover status sensor for detecting the opening and closing status of the upper cover and a seat ring status sensor for detecting the opening and closing status of the seat ring. The upper cover filling sensor and the seat ring status sensor can be pressure sensors, which can be installed on the bottom surfaces of the upper cover and the seat ring respectively. The opening and closing status of the upper cover and the seat ring can be judged by pressure changes, and whether there is a person on the seat ring can also be judged by the pressure sensor on the bottom surface of the seat ring.

[0029] When the cover plate status sensor detects that the seat ring is closed and the upper cover is closed, the environmental status sensor switches to the first detection mode; when the cover plate status sensor detects that the seat ring is closed and the upper cover is opened, the environmental status sensor switches to the second detection mode.

[0030] The signals detected by the environmental status sensor in the first detection mode are large-range human body signals and usage intention signals; the signals detected by the environmental status sensor in the second detection mode are small-range human body signals and large-range human body signals; the signals detected by the environmental status sensor in the urination detection mode are urination signals, small-range human body signals and large-range human body signals.

[0031] In the urination detection mode, the environment detection sensor detects the urine column to determine whether there is a urination start signal and a urination end signal. When the urination end signal is detected, the flushing component is started to flush. Alternatively, when the urination start signal is detected, the flushing component is started to flush after a preset time. Alternatively, when the urination end signal is detected and the small-range human body signal disappears, the flushing component is started to flush.

[0032] In this embodiment, the range of urine column (water column) detection for urine detection is a long water column larger than φ2*10mm. In actual use, the range value of the urine column (water column) can be set according to the applicable population of different ages.

[0033] First, the seat ring state sensor and the upper cover state sensor are used to detect the opening and closing states of the seat ring and the upper cover. When the seat ring and the upper cover are both detected to be in the closed state, the environmental sensor 4 switches to the first detection mode. At this time, the detected signal is a large-scale human body signal and a use intention signal. At this time, the signal is transmitted to the main control board, and the main control board controls the upper cover control component to start opening the upper cover;

[0034] At this time, the upper cover is opened and the seat is closed, and the environmental sensor 4 switches to the second detection mode. The second detection mode detects gesture signals and large-scale human body signals, and detects whether there is a gesture signal from the human body. When the gesture signal is detected, it also detects whether there is someone on the seat, that is, the seat detection mode. If there is someone, it is determined that someone is sitting. If there is no one, the signal is transmitted to the main control board and the seat control component is started by the main control board to start opening the seat;

[0035] When someone is judged to be in the seat mode, the seat heating component and / or voice component can be started through the main control panel, and the voice component can be used to detect the voice command issued by the person, and the voice component can be used to detect the voice command issued by the person to start the human body cleaning component, drying component, etc. and start the components with corresponding functions. After detecting that the human body has left the seat, the flushing component can be automatically started to flush, or the cleaning component, drying component, seat heating component, etc. can be started by setting corresponding buttons on the toilet.

[0036] When the seat state sensor is a pressure sensor, it is also possible to determine whether someone is sitting or leaving the seat by detecting the pressure change. In this case, the determination of whether someone is sitting is completed by the pressure sensor detection, and no environmental sensor is required for detection;

[0037] The upper cover is opened, the seat is opened, and the environmental sensor 4 is switched to the urination detection mode. When a urination signal is detected, a 10-second countdown is performed. If a urination signal is detected during the countdown, the countdown is restarted. After the countdown, the flushing component is started to flush. The specific countdown time is set according to actual needs. When it is detected that there is no one, the seat and the upper cover are closed through the seat control component and the upper cover control component.

[0038] The environmental sensor detects whether there is someone in the second preset area to determine whether there is a large-scale human signal. By detecting the speed of human movement and the length of stay in the first preset area, it determines whether there is an intention to use signal. The environmental sensor detects whether the human body makes a limb movement in the third preset area to determine it as a gesture signal. The environmental sensor determines whether there is someone in a small area in the third preset area to determine whether there is a small-range signal.

[0039] In the first detection mode, the environmental status sensor determines whether there is a use intention signal by detecting the speed of human movement or the stay time in the first preset area; the environmental status sensor determines whether there is a large-scale human signal by detecting whether there is someone in the second preset area. If there is a use intention signal, the upper cover will be opened through the upper cover control component. If there is no use intention signal, the upper cover will not be opened. If there is a large-scale signal, the various functional components of the toilet enter the standby state, and if there is no large-scale human signal, the smart toilet function enters sleep; in the second detection mode, the environmental status sensor determines whether there is a small-scale human signal by detecting whether there is someone in the third preset area, and determines whether there is a gesture signal by whether someone makes a body movement; in the second detection mode, the gesture signal is detected on the basis of detecting the presence of a large-scale human signal. If there is a gesture signal and a use intention signal, the seat will be opened through the seat control component.

[0040] The first preset area, the second preset area and the third preset area can be set according to different heights, ages and different sensors used, as long as the environmental sensor can detect the human body and the position where the human body makes corresponding actions;

[0041] Reference Figure 3Specifically, the detection orientation of the first preset area, the second preset area and the third preset area is fan-shaped, and the first preset area is located between the second preset area and the third preset area. When someone enters the second preset area, it is determined that there is a large-scale human body signal, and when the person stays in the second preset area for a certain time or moves at a certain speed to determine whether there is a use intention signal. Specifically, the stay time and the movement speed can be set as needed. When there is a large-scale signal and a use intention signal, the upper cover is opened;

[0042] The upper cover is opened, the environmental sensor switches to the second detection mode, and when the human body continues to pass through the second preset area and enters the third preset area, if a gesture or body movement made by the human body in the third preset area is detected, it is considered as a gesture signal, and the seat ring is opened at this time;

[0043] At this time, the seat cover and the seat are opened at the same time. After the seat is opened, the environmental sensor enters the third detection mode. At this time, the environmental sensor detects whether there is a urination signal in the third preset area. If there is a urination signal, the seat and the cover remain in the open state.

[0044] In this embodiment, the second preset area is larger than the first preset area and the second preset area, and the range of the second preset area may be equal to the sum of the ranges of the first preset area and the second preset area. In practice, it can be set according to actual needs.

[0045] More specifically, the gesture signal may be a human palm flip, hand waving, translation, hand raising and other actions, the gesture signal may be set by oneself, and the gesture signal may also be other body movements or pre-set actions, including but not limited to the above gestures;

[0046] The above-mentioned various functional components of the toilet entering the standby state means that the various functional components are ready to work.

[0047] The environmental state sensor also includes a seating detection mode, in which the environmental state detection sensor detects whether there is an object on the seat ring to determine whether there is a seating signal, and if there is a seating signal, it is determined to be seating.

[0048] When there is a large-scale human body signal in the first detection mode, the night light will be turned on when it is night, otherwise the night light will be turned off. That is, the night light will be turned on when a large-scale human body signal is detected when the human body enters the second preset area and the use environment is at night. The night light will only be turned on when both conditions are met. Otherwise, the night light will be turned off if only one condition is met.

[0049] The working process of the present invention is as follows: Figure 2As shown, first, the cover state sensor is used to detect whether the upper cover and the seat ring are in an open or closed state. When the upper cover and the seat ring are both in a closed state, the environmental sensor switches to the first detection mode. When a large range of human body signals are detected in the second preset area and a use intention signal is detected in the first preset area, the signal is transmitted to the main control board for processing. After the main control board calculates and processes the signal, the upper cover control component is started to open the upper cover;

[0050] When the upper cover is opened, the environmental sensor switches to the second detection mode. In the second detection mode, when the environmental sensor detects a gesture signal from a person and no one is on the seat, the signal is transmitted to the main control board. After the main control board calculates and processes the transmitted signal, it starts the seat control component to open the seat; when it detects that there is someone on the seat, it is determined to be in the seat mode;

[0051] When the upper cover and the seat are both open, the environmental sensor switches to the urination detection mode. When the environmental sensor detects a urination signal through the urine column, the upper cover and the seat are kept in the open state. When the urination signal disappears, the flushing component is started to flush.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
