Description

Technical Field

[0001] This utility model relates to the technical field of intelligent bathroom equipment, specifically to a sensing module integrating laser sensing and pattern projection, and an intelligent toilet. Background Technology

[0002] Early smart toilets were operated via control panels. With technological advancements, smart toilets have gained popularity due to their ability to perform increasingly sophisticated functions, such as automatic flushing and drying. However, these functions still require manual operation by pressing corresponding buttons on a remote control. The frequent use of certain buttons can cause wear and tear, even damage, to some of them. Furthermore, common remote controls need to be installed separately in a specific location within the bathroom, affecting its overall aesthetics. Additionally, remote control development is costly, and manual operation can increase the risk of cross-infection. Therefore, there is an urgent need for a smart toilet that can be controlled without physical contact. Utility Model Content

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figure 1-3 This embodiment provides a sensing module integrating laser sensing and pattern projection. The sensing module 8 is used to install on the side wall of a floor-mounted toilet. The sensing module 8 includes a housing assembly 1, a laser sensing module 2, a pattern projection module 3, and a control module 4. The housing assembly 1 has a first mounting cavity 11 and a second mounting cavity 12 spaced apart internally. The housing assembly 1 has a light-transmitting sidewall 14, and the first mounting cavity 11 and the second mounting cavity 12 share the light-transmitting sidewall 14. The laser sensing module 2 is disposed in the first mounting cavity 11 and electrically connected to the control module 4, and the pattern projection module 3 is disposed in the second mounting cavity 12 and electrically connected to the control module 4. The sensing area 21 of the laser sensing module 2 on the ground and the projection area 31 of the pattern projection module 3 on the ground at least partially overlap. The control module 4 is used to connect to external devices to control the external devices to perform preset functions based on the information from the laser sensing module 2. Thus, the laser sensing module 2 and the pattern projection module 3 are respectively installed in the first mounting cavity 11 and the second mounting cavity 12 in the housing assembly 1. The overall structure is compact and small in size, integrating laser sensing and pattern projection functions, which is convenient for assembly on the toilet 7; there is no need to use a contact remote control for control, avoiding cross-infection.

[0023] Furthermore, in this embodiment, the center of the sensing area 21 of the laser sensing module 2 and the center of the projection area 31 of the pattern projection module 3 coincide, ensuring the accuracy of the pattern projection indication. When the sensing module 8 is set horizontally, the light output path of the laser sensing module 2 is inclined downward relative to the horizontal plane, and similarly, the light output path of the pattern projection module 3 is inclined downward.

[0024] Furthermore, the laser sensing module 2 includes a transmitter 22 and a receiver 23, and an isolation plate 111 is provided in the first mounting cavity 11 to separate the transmitter 22 and the receiver 23. The isolation plate 111 prevents light crosstalk, which could cause the laser sensing module 2 to malfunction. The laser sensing module 2 includes a ranging chip, on which the transmitter 22 and the receiver 23 are arranged.

[0025] Furthermore, the pattern projection module 3 includes a light source 32, a miniature projection sheet 33, a lens 34, and a reflector 35. The light source 32, miniature projection sheet 33, lens 34, and reflector 35 are arranged sequentially and at intervals within the second mounting cavity 12. The miniature projection sheet 33 has a miniature pattern, which can be a logo, indicator icon, or other symbol. The reflector 35 is arranged at an angle relative to the lens 34 so that the light emitted from the light source 32 is reflected by the reflector 35 and then emitted from the light-transmitting sidewall 14. The light source 32 uses an LED light, which has flashing, gradation, and breathing modes, and is controlled by the control module 4.

[0026] Furthermore, the housing assembly 1 also includes a third mounting cavity 13, within which the control module 4 is installed. The control module 4 is connected to the laser sensing module 2 via a flexible wire, and similarly, it is connected to the light source 32 of the pattern projection module 3 via a flexible cable. The control module 4 is also connected to an external wiring harness 5, which extends out of the housing assembly 1 for connecting to external devices. The external wiring harness 5 also serves as a power supply harness for the entire sensing module 8. The control module 4 can receive signals from the laser sensing module 2 and provide feedback to external devices, and it can control the switching on / off state and illumination mode of the light source 32.

[0027] Furthermore, the housing assembly 1 includes an outer shell 15 and an inner shell 16, with the outer shell 15 fitted over the inner shell 16. The laser sensing module 2, the pattern projection module 3, and the control module 4 are installed inside the inner shell 16. One end wall of the outer shell 15 along its length serves as a light-transmitting sidewall 14, and the outer shell 15 is made of a white transparent material. The inner shell 16 is made of an opaque material and is open on the side facing the light-transmitting sidewall 14. The second mounting cavity 12 is divided into a first light cavity 121, a second light cavity 122, and a third light cavity 123 by the lamp source 32, the miniature projection sheet 33, the lens 34, and the light-transmitting sidewall 14. The opaque material of the inner shell 16 ensures the optical path isolation of the pattern projection module 3, preventing mutual interference between the light from the first light cavity 121, the second light cavity 122, and the third light cavity 123. The third mounting cavity 13 is located inside the inner shell 16.

[0028] Furthermore, the length of the outer shell 15 is greater than the length of the inner shell 16, and a cavity 6 is formed between the end wall of the inner shell 16 away from the light-transmitting side wall 14 and the inner wall of the outer shell 15. The external wiring harness 5 passes through the cavity 6 and then through the end wall of the inner shell 16 away from the light-transmitting side wall 14 to connect to the control module 4. The cavity 6 is used to fill with sealant to prevent the internal electronic components of the sensing module 8 from being damaged by moisture in a humid environment.

[0029] Furthermore, the inner housing 16 includes a first half-housing 161 and a second half-housing 162, with the first half-housing 161 detachably connected to the second housing. This facilitates the installation of the laser sensing module 2, the control module 4, and the pattern projection module 3 within the inner housing 16.

[0030] Furthermore, the housing assembly 1 also includes an outer rubber sleeve 17, which is fitted and fixed to the outer wall of the housing 15 and can be deformed by compression. The outer rubber sleeve 17 facilitates the interference fit of the entire sensing module 8 into the side wall hole of the toilet 7, enabling the detachable installation of the sensing module 8 and the toilet 7.

[0031] This embodiment also provides a smart toilet, including a toilet 7 and a sensor module 8 installed on the side wall of the toilet 7. The toilet 7 is a floor-standing toilet. Specifically, the control module 4 is connected to the main control board of the toilet 7. The control module 4 transmits the information fed back by the laser sensing module 2 to the main control board, and the main control board then controls the actuator to perform preset functions. That is, when the user's foot moves to the projection area 31 of the pattern projection module 3, it falls into the sensing area 21 of the laser sensing module 2. After receiving the information, the control module 4 transmits it to the main control board of the toilet 7, and the main control board controls the actuator to perform preset actions such as flushing or opening the lid, without the need for a contact remote control.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
