Description

Technical Field

[0001] The invention relates to the technical field of intelligent toilets, and in particular to an intelligent toilet control method based on a single infrared sensor. Background Art

[0002] The automatic flap function of a smart toilet usually uses two or more sensors to cooperate with each other to control the automatic flap of the toilet seat and toilet lid, as well as the automatic flushing of the toilet. Although this design improves the convenience and hygiene of use, it also increases the manufacturing cost of the toilet. The signals of multiple sensors work alternately with each other, which not only increases the technical complexity, but may also cause functional failure or reduced user experience due to signal interference or asynchrony between sensors. For example, if the sensitivity of the sensor is not set properly, it may cause the toilet lid to accidentally flip up when not needed, or not flip up when needed, causing inconvenience to the user. In addition, the increase in sensors also means an increase in the user's cost of use. Therefore, smart toilet manufacturers need to find a balance between improving product intelligence and controlling costs to ensure the product's cost-effectiveness and market competitiveness. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to propose an intelligent toilet control method based on a single infrared sensor to solve the problems mentioned in the above background technology section.

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

[0005] A smart toilet control method based on a single infrared sensor comprises the following steps:

[0006] Step S1, detecting by a gyroscope whether the toilet lid is in an open position or a closed position, when the gyroscope detects that the toilet lid is in the closed position and when the infrared sensor detects the target person, executing step S2, when the gyroscope detects that the toilet lid is in an open position and when the infrared sensor detects the target person, executing step S3;

[0007] Step S2, the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to open the toilet cover. In the process of the toilet cover switching from the closed position to the open position, the flipping mechanism drives the infrared sensor to flip so that the detection direction of the infrared sensor extends horizontally, and then enters step S3;

[0008] Step S3, the infrared sensor determines whether the target person is at the first distance or the second distance, and when the infrared sensor detects that the target person is within the range of the first distance, step S4 is executed; when the infrared sensor detects that the target person is within the range of the second distance, step S5 is executed; when the infrared sensor does not detect the target person, step S6 is executed;

[0009] Step S4, the infrared sensor transmits a signal to the controller to control the second opening and closing mechanism to open the toilet seat;

[0010] Step S5, the infrared sensor maintains a continuous monitoring state until the target person leaves the range of the second distance, and the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to close the toilet lid, and transmits a signal to the controller to control flushing;

[0011] Step S6: When the infrared sensor does not detect the target person within the first set time period, the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to close the toilet lid.

[0012] The beneficial effects of the present invention are as follows: the present invention provides an intelligent toilet control method based on a single infrared sensor, which cooperates with a gyroscope, a first opening and closing mechanism, a second opening and closing mechanism, and a flipping mechanism, so that when the toilet lid is in the open or closed position, the single infrared sensor detects in the horizontal direction, which is convenient for the target person to pass through the detection range, thereby realizing the control of the toilet lid, toilet seat and flushing, thereby improving the user experience.

[0020] 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. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] The present invention provides a smart toilet control method based on a single infrared sensor, wherein, referring to Figures 2 to 5 As shown, the smart toilet specifically includes a toilet body 1, a toilet cover 2 rotatably connected to the toilet body 1, a toilet seat 3 rotatably connected to the toilet body 1, a first opening and closing mechanism for controlling the opening and closing of the toilet cover 2, and a second opening and closing mechanism for controlling the opening and closing of the toilet seat 3, wherein the first opening and closing mechanism and the second opening and closing mechanism belong to the prior art. It also includes a gyroscope for detecting the flip angle of the toilet cover 2, a flip mechanism 4 rotatably connected to the toilet cover 2, and an infrared sensor arranged on the flip mechanism 4; when the gyroscope detects that the toilet cover 2 is switching between the open position and the closed position, the flip mechanism 4 drives the infrared sensor to flip so that the detection direction of the infrared sensor remains extended in the horizontal direction.

[0022] Through the cooperation of the gyroscope, the first opening and closing mechanism, the second opening and closing mechanism, the flip mechanism 4, etc., when the toilet lid 2 is in the open or closed position, the single infrared sensor detects in the horizontal direction, which is convenient for the target person to pass through the detection range, and then the toilet lid 2, toilet seat 3 and flushing are controlled, thereby improving the user experience and reducing the manufacturing cost of the smart toilet.

[0023] The method specifically comprises the following steps:

[0024] Step S1, detecting by a gyroscope whether the toilet lid 2 is in an open position or a closed position, when the gyroscope detects that the toilet lid 2 is in the closed position and when the infrared sensor detects the target person, executing step S2, when the gyroscope detects that the toilet lid 2 is in an open position and when the infrared sensor detects the target person, executing step S3;

[0025] Step S2, the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to open the toilet cover 2. When the toilet cover 2 is switched from the closed position to the open position, the flipping mechanism 4 drives the infrared sensor to flip so that the detection direction of the infrared sensor extends horizontally, and then enters step S3;

[0026] Step S3, the infrared sensor determines whether the target person is at the first distance or the second distance, and when the infrared sensor detects that the target person is within the range of the first distance, step S4 is executed; when the infrared sensor detects that the target person is within the range of the second distance, step S5 is executed; when the infrared sensor does not detect the target person, step S6 is executed;

[0027] Step S4, the infrared sensor transmits a signal to the controller to control the second opening and closing mechanism to open the toilet seat 3;

[0028] Step S5, the infrared sensor maintains a continuous monitoring state until the target person leaves the range of the second distance, and the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to close the toilet lid 2, and transmits a signal to the controller to control flushing;

[0029] Step S6: When the infrared sensor does not detect the target person within the first set time period, the infrared sensor transmits a signal to the controller to control the first opening and closing mechanism to close the toilet lid 2.

[0030] Furthermore, in step S4, the infrared sensor maintains a continuous monitoring state until the target person leaves the range of the first distance, and the infrared sensor transmits a signal to the controller to control the second opening and closing mechanism to close the toilet seat 3, and transmits a signal to the controller to control the first opening and closing mechanism to close the toilet lid 2, and transmits a signal to the controller to control flushing.

[0031] Furthermore, in step S5, when the target person is at the second distance for a time period exceeding a second set time period, the infrared sensor transmits a signal to the controller to control the sedentary reminder mechanism to start reminding.

[0032] Among them, the reminders include sedentary reminders and accident reminders. The second set time corresponding to the sedentary reminder is any value between 5min and 15min, and the second set time corresponding to the accident reminder is any value between 15min and 30min. When the target person uses the toilet for a period of time exceeding the sedentary reminder, a sedentary reminder will be issued. Sitting on the toilet for a long time can easily affect blood circulation and increase the risk of hemorrhoids. And if the target person is an elderly or disabled person, when the use time exceeds the accident reminder time, an accident reminder will be issued to avoid accidents to the target person using the toilet.

[0033] Furthermore, in step S6, the first set time length is 5s to 10s.

[0034] Furthermore, the first distance ranges from 0.6 meters to 1.5 meters, and the second distance ranges from 0 to 0.5 meters.

[0035] When in use, the infrared sensor sends out a detection signal. When the gyroscope detects that the toilet lid 2 is in the closed position and when the infrared sensor detects the target person, the toilet lid 2 automatically opens. In the process of the toilet lid 2 switching from the closed position to the open position, the flipping mechanism 4 drives the infrared sensor to flip.

[0036] When the gyroscope detects that the toilet lid 2 is completely opened, the infrared sensor is used to determine the distance between the target person and the toilet lid 2.

[0037] When the infrared sensor detects that the target person is within the range of the first distance, it indicates that the user is in a standing urinating state. At this time, the infrared sensor transmits a signal to the controller to control the second opening and closing mechanism to open the toilet seat 3, and waits for the target person to finish urinating, that is, when the target person leaves the range of the first distance, the toilet seat 3 and the toilet lid 2 are closed, and then flushing is performed.

[0038] When the infrared sensor detects that the target person is within the range of the second distance, it indicates that the user is sitting or standing to use the toilet. At this time, the infrared sensor maintains a continuous monitoring state until the target person leaves the range of the second distance, the toilet lid 2 is closed, and then flushing is performed.

[0039] When the infrared sensor fails to detect that the target person is within the detection range, the toilet lid 2 automatically closes after waiting for a first set time.

[0040] The endpoints set by the first distance range and the second distance range do not overlap, so as to avoid ambiguity in judgment when the user is at the endpoint position. Preferably, the infrared sensor is a transceiver integrated sensor, the power of the infrared sensor is constant, and the user distance is identified by the infrared sensor, so as to judge whether the user is in the first distance range or the second distance range, without adjusting the driving power of the infrared sensor, which is convenient for programming operation of the above method, and without reciprocatingly adjusting the driving power of the infrared sensor, resulting in misjudgment caused by power switching error.

[0041] The present invention provides an embodiment of the flipping mechanism 4, which is specifically as follows:

[0042] Reference Figures 3 to 5 As shown, the first embodiment of the flip mechanism 4 is: the flip mechanism 4 is a mounting shell 41, the mounting shell 41 is rotatably connected to the toilet cover 2, the infrared sensor is fixed in the mounting shell 41, and the mounting shell 41 is a light-upper-and-heavy-lower structure. Under the action of gravity, when the toilet cover 2 is in the open position or the closed position, the detection direction of the infrared sensor expands in the horizontal direction.

[0043] Specifically, the toilet cover 2 is fixed with two installation plates 22 arranged at intervals, and a rotating shaft 23 connecting the two installation plates 22. The upper end of the installation shell 41 is rotatably connected to the toilet cover 2 through the rotating shaft 23. The weight of the side of the installation shell 41 away from the rotating shaft 23 is greater than the weight of the side of the installation shell 41 close to the rotating shaft 23. Through the principle similar to that of a tumbler, the installation shell 41 is kept vertical. When the toilet cover 2 is rotating, the detection direction of the infrared sensor expands in the horizontal direction.

[0044] Furthermore, the flip mechanism 4 also includes a connecting rope 42, one end of the connecting rope 42 is connected to the mounting shell 41, and the other end of the connecting rope 42 is connected to the toilet cover 2. When the toilet cover 2 is in the closed position, the connecting rope 42 is taut and makes the angle between the mounting shell 41 and the toilet cover 2 less than 90°, so that the detection angle of the infrared sensor is tilted toward the ground, which is in line with the usage scenario, and when the toilet cover 2 is rotated from the open position to the closed position, the lower end of the mounting shell 41 abuts against the toilet body 1 or the toilet seat 3 and can only be rotated in the connection direction of the connecting rope 42 and the toilet cover 2.

[0045] Among them, the toilet cover 2 is provided with an extension part 21 protruding from the toilet body 1, and the extension part 21 is provided with a light-transmitting hole 211 for the infrared sensor to transmit light. The extension part 21 is provided with an installation chamber for installing the flip mechanism 4. By hiding the flip mechanism 4 in the toilet cover 2, the overall product is beautiful.

[0046] A clearance groove 31 of the clearance flip mechanism 4 can be provided on the toilet seat 3 to reduce the overall thickness of the toilet cover 2 and the toilet seat 3, making the overall structure of the toilet more compact.

[0047] When in use, the infrared sensor sends out a detection signal. When the gyroscope detects that the toilet lid 2 is in the closed position and when the infrared sensor detects the target person, the toilet lid 2 automatically opens. In the process of the toilet lid 2 switching from the closed position to the open position, the flipping mechanism 4 drives the infrared sensor to flip.

[0048] When the gyroscope detects that the toilet lid 2 is completely opened, the infrared sensor is used to determine the distance between the target person and the toilet lid 2.
