Description

Technical Field

[0002] Currently, most smart toilets achieve lid flipping and flushing by setting a mechanical switch or sensor switch at the bottom of the side.

[0003] The induction switch mainly includes laser sensing and infrared sensing. During installation, a rubber sleeve is usually put on the outside of the shell and then inserted into the installation hole of the toilet. When the rubber surface is wet, the friction with the ceramic surface will decrease a lot. When the user touches the product when cleaning the toilet or mopping the floor, it is easy to cause it to rotate and change its sensing area, which will cause the product to be unable to be used normally. In addition, the rubber sleeve will expand and rebound after compression, causing the product that has been installed to rebound after a period of use and significantly protrude from the ceramic surface, affecting the user experience.

[0004] In addition, the current infrared sensing device has a complex structure, which leads to an increase in the number of parts, affecting production costs and installation difficulty. Utility Model Content

[0016] The second object of the present invention is to provide an electronic device comprising the infrared sensing device as described above.

[0017] Compared with the prior art, the present invention has significant advantages and beneficial effects, which are specifically reflected in the following aspects:

[0018] The infrared sensing device realizes high-precision detection of objects by emitting lasers and detecting the reflected laser beams. The tubular bracket is composed of a tube body and two arc columns (a first arc column and a second arc column).

[0039] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0040] To solve the above problems, Figure 1-6 As shown, the embodiment of the present invention provides an infrared sensing device, including a tubular support 3, a laser sensing body 5 and an electronic wire 6, wherein:

[0041] The tubular bracket 3 includes a tube body 31 and a first arc column 32 and a second arc column 33 symmetrically and evenly spaced on the outer circumference of one end of the tube body 31. The first arc column 32 and the second arc column 33 extend along the central axis of the tube body 31; the laser sensing body 5 is suitable for being obliquely supported and connected to the end of the first arc column 32 and the second arc column 33 away from the tube body 31. The laser sensing body 5 includes a PCBA board 51, a laser emitting tube 52, a laser receiving tube 53 and an indicator light 54 installed on one side of the PCBA board 51, and a terminal 56 installed on the other side of the PCBA board 51; an isolation cover 55 integrally connected to the PCBA board 51 is provided on the outside of the laser emitting tube 52 and the laser receiving tube 53; one end of the electronic wire 6 is located in the tube body 31, and a bell mouth 312 is provided inside the side of the tube body 31 away from the PCBA board 51. The electronic wire 6 is suitable for passing through the bell mouth 312 and electrically connected to the terminal 56.

[0042] Thus, the infrared sensing device achieves high-precision detection of objects by emitting laser light and detecting the reflected laser beam. This infrared sensing device takes into account stability, anti-interference, and adaptability, and can be widely used in various automatic control and detection scenarios. The tubular support 3 consists of a tubular body 31 and two curved columns (a first curved column 32 and a second curved column 33). These two curved columns extend along the central axis of the tubular body 31 and are symmetrically distributed on the outer circumference of one end of the tubular body 31. Such a design helps to stably support the laser sensor body 5 and helps to adjust the angle of laser emission and reception; the laser sensor body 5 includes a PCBA board 51, a laser emitting tube 52, a laser receiving tube 53, an indicator light 54, an isolation cover 55 and a terminal 56. These components together realize the emission, reception and signal processing of the laser, wherein the laser emitting tube 52 is located on one side of the PCBA board 51 to emit a laser beam. When the laser beam encounters an obstacle, it will be reflected back. At this time, the laser receiving tube 53 is located on the other side of the PCBA board 51 to receive the reflected laser beam; the outside of the laser emitting tube 52 and the laser receiving tube 53 is provided with an isolation cover 55 that is integrally connected to the PCBA board 51, which can not only be completed by integral casting, but also reduce the number of parts and avoid later installation. The light 54 is used to indicate the working status of the device. For example, when an object is detected, the light 54 may light up or flash. The terminal 56 is used to connect the electronic wire 6 to achieve connection with the external circuit and signal transmission. One end of the electronic wire 6 is located in the tube body 31, and the other end passes through the horn 312 provided inside the side of the tube body 31 away from the PCBA board 51 and is electrically connected to the terminal 56. This design can protect the electronic wire 6 from being affected by the external environment, and is also convenient for installation and maintenance. The processed signal is transmitted to the external circuit through the electronic wire 6, and the control system determines whether an object passes according to the received signal and performs corresponding actions, such as triggering an alarm, opening a door, etc.

[0043] For further information, see Figure 4 As shown, the end of the first arc column 32 away from the tube body 31 has an inclined support portion, and the height of the first arc column 32 is lower than the height of the second arc column 33.

[0044] Therefore, one end of the first curved column 32 has a tilted support portion, the purpose of which is to adapt the PCBA board 51 to a specific installation angle or space limitation, and further provide additional support and stability to the PCBA board 51; the height of the first curved column 32 is lower than the height of the second curved column 33, and this height difference is mainly used to adjust the emission and receiving angles of the laser sensing body 5.

[0045] For further information, see Figure 1As shown, the two second arc columns 33 are respectively provided with a first boss 331 and a second boss 332 on the inner wall of the side away from the tube body 31, and the first boss 331 is located on the high point side close to the support part, and the second boss 332 is located on the low point side close to the support part.

[0046] Specifically in this embodiment, the arrangement of the first boss 331 and the second boss 332 is related to the tilt support connection of the laser sensing body 5 , and their positions and designs help to adjust the angle and position of the laser sensing body 5 to adapt to different installation and usage requirements.

[0047] For further information, see Figure 1 As shown, the infrared sensing device also includes an optical window 1 covered on the outside of the tubular bracket 3 and the laser sensing body 5, the first end 11 of the optical window 1 has a sensing window, and the second end 12 of the optical window 1 has an opening 121, wherein the first end 11 has a concave arc surface 111, and the sensing window is formed on the concave arc surface 111; one end of the tubular bracket 3 located at the first arc column 32 and the second arc column 33 is suitable for being inserted into the optical window 1 through the opening 121 of the second end 12, so that the laser sensing body 5 is close to the sensing window side of the optical window 1.

[0048] Thus, the optical window 1 is covered on the outside of the tubular bracket 3 and the laser sensing body 5. The first end 11 of the optical window 1 has a sensing window, and the second end 12 has an opening 121. The sensing window of the first end 11 is set on the concave arc surface 111, which helps to concentrate and guide the laser beam and receive the reflected laser beam.

[0049] For further information, see Figure 2 、 3 As shown in Figure 4, the infrared sensing device also includes a sealing ring 4 arranged between the tubular bracket 3 and the optical window 1. A sealing groove 311 is provided on the outer circumference of the tube body 31 on the side away from the laser sensing body 5. The sealing ring 4 is suitable for being installed in the sealing groove 311 so that the outer ring of the sealing ring 4 is suitable for being squeezed on the inner wall of the optical window 1.

[0050] Therefore, the sealing ring 4 is arranged between the tubular bracket 3 and the optical window 1. Its main purpose is to ensure that the working environment of the laser sensing body 5 is isolated from the external environment, preventing external dust, moisture or other pollutants from entering, thereby ensuring the accuracy of laser sensing and the long-term stability of the device.

[0051] For further information, see Figure 2 、 3 As shown, the infrared sensing device also includes a sealing sleeve 2 mounted on the outer circumference of the optical window 1. An inner stop is provided inside the sealing sleeve 2 on the side away from the optical window 1, and the second end 12 of the optical window 1 is suitable for abutting against the inner stop of the sealing sleeve 2.

[0052] Thus, the provision of the sealing sleeve 2 further enhances the protection performance of the device and ensures a stable working environment for the laser sensor body 5. Through the design of the inner stop, the sealing sleeve 2 and the optical window 1 are tightly matched, ensuring that the working environment of the laser sensor body 5 is effectively isolated from the external environment.

[0053] For further information, see Figure 2 As shown, the infrared sensing device further includes a decorative ring 21 sleeved on the outer peripheral wall of the sealing sleeve 2 close to the first end 11 , and the decorative ring 21 is suitable for covering the outer circumference of the concave arc surface 111 .

[0054] Therefore, the addition of the decorative ring 21 not only improves the appearance of the device, but also plays a certain auxiliary role in the protection and function of the device.

[0055] Another embodiment of the present invention further provides an electronic device, comprising the infrared sensing device as described above.

[0056] This enables the electronic device to detect the target object without touching it, which is very useful for application scenarios where physical contact needs to be avoided, such as in medical equipment or industrial automation.

[0057] Second, the electronic device can quickly respond to changes in the target object and provide immediate feedback, which is crucial for systems that require fast reactions.

[0058] The above disclosure of the present invention is intended to protect the present invention in a manner not limited to the above disclosure. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and such changes and modifications shall fall within the scope of protection of the present invention.
