Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to an intelligent toilet sensor device and toilet that facilitates the identification of the sensing area. Background Technology

[0002] With the popularization of smart home technology, smart toilets have gradually become mainstream products in the bathroom market due to their automated functions (such as automatic lid opening and flushing). In existing technologies, toilet foot switches detect the user's foot or leg movements through infrared sensing, microwave sensing, etc., to achieve contactless control. For example, the smart toilet foot switch disclosed in Chinese patent document CN222745222U identifies user movements through the sensing area and triggers corresponding functions, effectively improving the convenience and hygiene of use.

[0003] However, these foot-activated switches still have significant drawbacks in practical applications: the sensing area lacks clear markings, making it difficult for users to quickly and accurately determine the position of their feet or legs, causing the toilet to malfunction (such as failing to open the lid or accidentally flushing), thus affecting the smoothness of use. Existing solutions include marking the "sensor area" on the toilet shell, but this method relies on the user's visual perception and the markings are easily blurred by water stains and dirt. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose an intelligent toilet sensor device and toilet that facilitates the identification of the sensing area, so as to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution:

[0006] A smart toilet sensor device for easy identification of sensing areas includes a toilet body and a projection identification sensing device disposed on the toilet body. The projection identification sensing device includes a detection element and a projection element. The detection element emits a detection signal to the ground to create a detection area, and the projection element projects a graphic image to the ground to create a display area. The distance between the display area and the toilet body is smaller than the distance between the detection area and the toilet body.

[0007] Furthermore, it also includes a connecting component, which includes a mounting shell and connectors disposed at both ends of the mounting shell. The connectors are rotatably connected to the mounting shell, and the other end of the connectors is fixedly connected to the toilet body. The projection marking sensor is built into the mounting shell.

[0008] Furthermore, the mounting shell has connection portions at both ends that connect to the two connecting members. The outer circumference of the connection portion is arranged with a plurality of grooves. The connecting member has a plurality of protrusions that are embedded in the grooves. The connection portion has a limiting rib extending along the axial direction. The mounting shell has two limiting blocks that cooperate with the limiting rib.

[0009] Furthermore, the projection marking sensing device also includes a light-blocking sleeve with a light-transmitting hole, the projection element is built into the light-transmitting hole, and the detection element is fixedly connected to the light-blocking sleeve.

[0010] Furthermore, the angle between the central axis of the projection element and the detection element is 2° to 8°.

[0011] Furthermore, the projection components include LED lights, film, and lens arranged sequentially from the inside out.

[0012] Furthermore, the detection component is a position-sensitive detector.

[0013] On the other hand, this utility model provides a toilet, including an intelligent toilet sensor device as described in any of the preceding claims, which facilitates the identification of the sensing area.

[0014] The beneficial effects of this utility model are as follows: A smart toilet sensor device that facilitates the identification of the sensing area includes a toilet body and a projection identification sensor device disposed on the toilet body. The projection identification sensor device includes a detection element and a projection element. The detection element emits a detection signal from the ground to create a detection area, and the projection element projects a graphic image onto the ground to create a display area. The distance between the display area and the toilet body is smaller than the distance between the detection area and the toilet body. With the above settings, when a user's foot or leg enters the display area, it will first pass through the detection area. The detection area identifies the user's leg or foot movement, enabling the toilet lid and toilet seat to open or close, effectively improving ease of use and hygiene. The display area provides visual guidance, ensuring that the user can accurately pass through the detection area and thus control the toilet to perform corresponding actions, especially in low light conditions or first-time use scenarios, improving operational efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figures 1 to 7 As shown, a smart toilet sensor device for easy identification of the sensing area includes a toilet body 1 and a projection identification sensor 2 disposed on the toilet body 1. The projection identification sensor 2 includes a detection element 21 and a projection element 22. The detection element 21 emits a detection signal from the ground to have a detection area 21A, and the projection element 22 projects a graphic image 22A towards the ground. The distance between the graphic image 22A and the toilet body 1 is smaller than the distance between the detection area 21A and the toilet body 1.

[0026] When in use, when the user's feet or legs enter the display area 22A, they will first pass through the detection area 21A. The detection area 21A identifies the user's leg or foot movement and controls the opening or closing of the toilet lid and toilet seat, effectively improving convenience and hygiene. The display area 22A provides visual guidance to ensure that the user can accurately pass through the detection area 21A and control the toilet to perform the corresponding actions, especially in low light or first-time use scenarios, improving operational efficiency.

[0027] Reference Figure 2 and Figure 3 As shown, the black area is the detection area 21A, and the red area is the display area 22A. Preferably, the detection element 21 and the projection element 22 are emitted directly in front of the toilet's central axis. The user can kick their leg, and when the user's toes enter the display area 22A, their foot will sweep across the detection area 21A, thereby controlling the opening or closing of the toilet lid and toilet seat. This is simple to operate and avoids user misoperation.

[0028] The system also includes a connecting component 3, which comprises a mounting shell 31 and connectors 32 disposed at both ends of the mounting shell 31. The connectors 32 are rotatably connected to the mounting shell 31, and the other end of each connector 32 is fixedly connected to the toilet body 1. The projection indicator sensor 2 is built into the mounting shell 31. Users can adjust the distance between the detection area 21A of the projection indicator sensor 2 and the toilet body 1 by rotating the mounting shell 31, allowing for adaptive adjustments based on user needs and bathroom size to meet the personalized needs of different user groups.

[0029] The mounting shell 31 has connection portions at both ends that connect to the two connecting members 32. The outer circumference of the connection portion is arranged with a plurality of grooves 311. The connecting member 32 has a plurality of protrusions 321 that are embedded in the grooves 311. The connection portion has a limiting rib 312 extending axially. The mounting shell 31 has two limiting blocks 322 that cooperate with the limiting rib 312.

[0030] When it is necessary to adjust the distance between the detection area 21A and the toilet body 1, the mounting shell 31 is grasped and rotated. At this time, the protrusion 321 of the connector 32 and the groove 311 of the connecting part sequentially engage, thereby achieving fine adjustment of the tilt angle of the detection area 21A. When the appropriate angle is reached and the mounting shell 31 is released, the protrusion 321 and the groove 311 fit tightly together, forming a limiting structure that effectively restricts the arbitrary rotation of the mounting shell 31, ensuring that the angle of the detection area 21A remains stable.

[0031] With the cooperation of the two limiting blocks 322 and the limiting ribs 312, the rotation angle of the mounting shell 31 can be adjusted between 36° and 72°.

[0032] The connecting assembly 3 also includes a screw 33 and a washer 34 disposed between the screw 33 and the connector 32. The screw 33 is threadedly connected to the connecting part, thereby enabling the assembly of the connector 32 and the mounting housing 31.

[0033] The projection label sensing device 2 also includes a light-blocking sleeve 23, which has a light-transmitting hole 231. The projection element 22 is built into the light-transmitting hole 231, and the detection element 21 is fixedly connected to the light-blocking sleeve 23. Through these settings, the light source can be effectively constrained and guided, concentrating the light in a specific direction and area, avoiding light scattering and diffuse reflection, thereby improving the brightness of the display area 22A and achieving a clearer and brighter display effect.

[0034] Reference Figure 7 As shown in angle A, the angle between the projection element 22 and the detection element 21 is 2°~8°, thereby avoiding the display area 22A and the detection area 21A being too far apart, so that when the user operates the toilet, he / she can more intuitively combine visual observation with actual detection results, thus improving the operating experience.

[0035] Furthermore, the projection element 22 includes an LED lamp 211, a film 212, and a lens 213 arranged sequentially from the inside out. The LED lamp 211 serves as the light source, emitting light that first passes through the film 212. The film 212 provides initial control and guidance for the light, ensuring a more uniform distribution and propagation in a specific direction. Subsequently, the light enters the lens 213, which further focuses and collimates the light, projecting it more concentratedly and directionally onto the target area. This structure effectively improves light utilization efficiency, reduces light scattering and loss, and ensures that more light accurately reaches the display area 22A, thereby enhancing the brightness and clarity of the display area 22A. Furthermore, the film 212 can carry preset image or pattern information. When light passes through the film 212, it will image or display a specific graphic according to the pattern on the film 212, giving the display area 22A specific text or image markings.

[0036] Furthermore, the detection element 21 is a position-sensitive detector, i.e., PSD. The signal output by the PSD is stable and less affected by environmental factors (such as temperature and humidity). This allows the PSD to maintain a stable working state under various environmental conditions, making it suitable for the humid working environment of the toilet and ensuring its service life.

[0037] The projection sign sensing device 2 also includes a circuit board 24. During assembly, the lens 213, film 212, LED light 211, and position sensitive detector are first installed in the light-blocking sleeve 23, and then installed in the mounting shell 31. The circuit board 24 is used to press the light-blocking sleeve 23 and the mounting shell 31 together in an inverted fit.

[0038] On the other hand, this utility model provides a toilet, including a smart toilet sensor device as described in any of the above claims that facilitates the identification of the sensing area, so that the toilet has the beneficial effects of the smart toilet sensor device that facilitates the identification of the sensing area. When the user's foot or leg enters the display area 22A, it will scan the detection area 21A, thereby realizing the automatic opening or closing of the toilet lid and toilet seat.
