[0056] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0057] In this article, the term "comprising" is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0058] In a first aspect, this embodiment discloses Figure 1 A method for identifying a cleaning position based on an intelligent toilet is shown, the method comprising the following steps:

[0059] Configure smart toilet, such as Figure 2 and Figure 3 As shown, the smart toilet includes a toilet seat body 1, a toilet seat ring 2 installed on the toilet seat body 1, a spray rod 3 installed in the toilet seat body 1, and a laser sensor 4 arranged on the upper side of the nozzle on the spray rod 3. Here, the spray rod 3 includes a mounting end and a nozzle end. As the name implies, the mounting end is an end mounted with the toilet seat body 1, and the nozzle end is an end of the spray rod 3 for spraying water;

[0060] Detect whether cleaning is needed; when cleaning is detected, the spray bar 3 is started to move outward from the initial position (i.e. the position when it is not moved), and the laser sensor 4 performs a distance scan of the user's buttocks as the spray bar 3 moves outward;

[0061] Calculate the distance between each scanning point collected by the laser sensor 4 and the plane where the toilet seat 2 is located and form a buttocks contour;

[0062] Comparing the obtained buttocks contour with the cleaning position data pre-stored in the storage module to obtain the cleaning position;

[0063] Based on the cleaning position, the spray bar 3 moves and sprays water to clean the user's buttocks.

[0064] In this embodiment, detecting whether cleaning is required specifically includes:

[0065] A plurality of seat sensors 5 are provided on the toilet seat 2. The installation positions of the seat sensors 5 are as follows: Figure 3 As shown;

[0066] When the seat sensor 5 does not detect that a user sits on the smart toilet, it indicates that cleaning is not required;

[0067] When the seat sensor 5 detects that a user sits on the smart toilet, it determines whether a cleaning instruction is issued. If a cleaning instruction is issued, it means that cleaning is required, otherwise, it means that cleaning is not required. It should be noted that the cleaning instruction can be issued by the user manually through the relevant control component. Specifically, for example, when the user finishes using the toilet and does not stand up, by pressing the control component (such as a button), it means that a cleaning instruction is issued.

[0068] The spray rod structures commonly used in smart toilets on the market include straight spray rods (i.e., spray rod structures with an overall straight structure) and curved spray rods (i.e., spray rod structures with an overall curved structure). For spray rod structures of different shapes, it is unreasonable to use the same algorithm to determine the position that needs to be cleaned. It may even cause cleaning errors due to factors such as the user's body shape or the influence of the algorithm itself, which has a great impact on the user's experience. In this regard, the present application provides algorithms corresponding to when the spray rod 3 is a straight spray rod and when the spray rod 3 is a curved spray rod. See below for details.

[0069] In this embodiment, combined with Figure 4 As shown, when the spray rod 3 is a straight spray rod, the laser beam of the laser sensor 4 is set vertically to the top of the spray rod 3, and the distance between each scanning point collected by the laser sensor 4 and the plane where the toilet seat 2 is located is calculated, specifically including:

[0070] The distance L between the user's buttocks and the plane where the toilet seat 2 is located straight Calculated by the following formula:

[0071] L straight =b×sin(β)+Ca×cos(β)

[0072] Wherein, C is the distance between the nozzle of the spray bar 3 and the plane where the toilet seat 2 is located in the initial state, b is the distance moved by the spray bar 3, a is the distance between the spray bar 3 and the user's buttocks obtained by scanning with the laser sensor 4, and β is the acute angle between the spray bar 3 and the plane where the toilet seat 2 is located;

[0073] Based on the distance L straight The calculation formula is used to obtain the distance between the user's buttocks and the plane where the toilet seat 2 is located corresponding to each position of the spray rod 3 during movement.

[0074] In this embodiment, combined with Figure 5 and 6 As shown, when the spray rod 3 is an arc-shaped spray rod, the laser beam of the laser sensor 4 is set perpendicular to the top of the spray rod 3, and the distance between each scanning point collected by the laser sensor 4 and the plane where the toilet seat 2 is located is calculated, specifically including:

[0075] The distance L between the user's buttocks and the plane where the toilet seat 2 is located curved Calculated by the following formula:

[0076] L curved =R×cos(θ)+C-(a+R)×cos(θ+ω)

[0077] Wherein, C is the distance between the nozzle of the spray rod 3 and the plane where the toilet seat 2 is located in the initial state, R is the arc radius corresponding to the arc spray rod, a is the distance between the laser sensor 4 and the user's buttocks, ω is the movement angle formed by the nozzle of the spray rod 3 after the spray rod 3 moves and the nozzle in the initial state with the center of the arc corresponding to the arc spray rod, θ is the acute angle formed by the nozzle of the spray rod 3 and the vertical plane with the center of the arc corresponding to the arc spray rod in the initial state;

[0078] Based on the distance L curved The calculation formula is used to obtain the distance between the user's buttocks and the plane where the toilet seat 2 is located corresponding to each position of the spray rod 3 during movement.

[0079] Based on the above, by designing corresponding algorithms for spray bars 3 of different structural shapes, the optimized distance between the user's buttocks and the plane where the toilet seat 2 is located is obtained, thereby ensuring accurate acquisition of the cleaning position and improving the user experience.

[0080] In summary, the method for identifying the cleaning position based on the smart toilet provided in this embodiment scans the user's buttocks through the laser sensor 4 that moves with the spray rod 3 to obtain the user's buttocks position and buttocks shape, and then determines the cleaning position based on the comparison of the buttocks model, and finally sprays water to clean the cleaning position, ensuring that users of different body shapes can accurately clean the buttocks part that needs to be cleaned when using it, thereby improving the user experience.
