Description

Technical Field

[0001] The utility model belongs to the technical field of infrared switches, and particularly relates to a novel infrared switch. Background Art

[0002] An infrared switch is an automatic control switch based on infrared sensing technology. It realizes its automatic control function by sensing the infrared heat emitted from the outside world. Specifically, this switch can quickly turn on various electrical equipment such as lamps, automatic doors, and burglar alarms. The working principle of the infrared switch is mainly based on passive infrared sensing technology, and its core sensing device is the human body pyroelectric infrared sensor.

[0003] A Chinese patent with publication number "CN220342300U" discloses a new type of infrared switch, including an optical system, a detection element and a conversion circuit. The detection element is encapsulated in a hemispherical receiving cover. The detection element is divided into a photoelectric detection element. The inner side of the receiving cover is an inner cover surface composed of multiple convex lenses. The focus of the convex lenses is concentrated on the photoelectric detection element. A rotating shielding mechanism is arranged in the middle of the base of the photoelectric detection element. The shielding piece is fan-shaped. There are at least two photoelectric detection elements, and the shielding piece covers one of the photoelectric detection element areas at a time.

[0004] However, the shells of existing infrared switches are mostly connected by a bottom shell and a top cover, and then combined by screw fixing. When the shell needs to be disassembled to check the internal workpiece, the user needs to first screw out each corresponding bolt from the screw hole, and then open the connected top cover to check the internal workpiece. This is inconvenient for disassembly and assembly, and also reduces the efficiency of later maintenance of the internal workpiece of the shell. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a new type of infrared switch to solve the problems mentioned in the background technology.

On the inner side of the protective shell, the bottom end of the bottom shell is threadedly connected to a mounting frame, and a strip opening is opened on one side of the mounting frame, which passes through the mounting frame and passes through the spring seat, so as to facilitate the up and down shaking of the mounting plate. When the top cover needs to be opened to view the interior of the bottom shell, the user can directly pull the top cover through the sliding principle. When the top cover is pulled, the bottom corner of the top cover will slide along the inclined surface of the protrusion. Affected by the inclined surface, the protrusion will be pressed downward accordingly, and the protrusion can drive the mounting plate to be pressed downward together, thereby avoiding the workpiece on the top of the mounting plate from colliding with the bottom end of the top cover. The top cover can be directly removed through the sliding principle, thereby achieving the purpose of convenient disassembly and assembly of the top cover.

[0008] As a preferred technical solution, a first sliding groove matching the mounting plate is provided on the inner wall of the bottom shell, and the outer wall of the mounting plate is slidably connected to the inner wall of the bottom shell through the first sliding groove. The opening of the first sliding groove facilitates the up and down sliding of the mounting plate, and while not hindering the pushing and retracting elastic force of the spring seat, the height adjustment angle of the mounting plate can be effectively limited, thereby effectively improving the stability of the height adjustment of the mounting plate.

[0009] As a preferred technical solution, a second slide groove is opened at the top of the bottom shell, and a slider matching the second slide groove is fixedly connected to the bottom end of the top cover. The top cover is slidably connected to the top of the bottom shell through the second slide groove and the slider. A handle is fixedly connected to the top of the top cover. The shape of the handle is concave, and the shape of the corner of the handle is arc-shaped. The second slide groove is opened to facilitate the front and back sliding of the top cover. The handle can provide the user with a gripping point, and it will be more convenient and quick to pull the top cover open through the handle.

[0010] As a preferred technical solution, a socket is provided at the top of the top cover, and the sockets pass through the top of the top cover and the top of the bottom shell. A plug-in board is plugged into the inner side of the socket, and the bottom end of the plug-in board is plugged into the interior of the bottom shell through the socket. By inserting the plug-in board into the socket, the position of the top cover can be effectively limited, which not only avoids the displacement of the top cover position, but also effectively improves the stability of the top cover position fixation.

[0011] As a preferred technical solution, a first screw hole is provided at the top of the connecting plate, and the first screw holes penetrate the top of the connecting plate and the top cover. The inner side of the first screw hole is threadedly connected with a first bolt, and the bottom end of the first bolt is threadedly connected to the inside of the top cover through the first screw hole. The connecting plate is threadedly connected to the top of the top cover through the first screw hole and the first bolt, and the first bolt is screwed into the first screw hole, so that the position of the connecting plate can be effectively fixed. When the connecting plate needs to be removed, the first bolt can be screwed out of the first screw hole. After the connecting plate is removed, the protective cover will also be taken out together. Through the circular hole, the user can also directly view the internal workpiece of the bottom shell.

[0012] The filter plate can effectively filter the air circulating through the vent, and can also effectively protect the inner side of the vent, and the dustproof cloth can block a large amount of dust and pollutants in the air, thereby preventing dust or pollutants from entering the interior of the bottom shell through the vent and causing damage to the workpiece.

[0013] As a preferred technical solution, a second screw hole is provided at the bottom end of the mounting bracket, and the second screw holes both penetrate the bottom ends of the mounting bracket and the bottom shell, a second bolt is threadedly connected to the inner side of the second screw hole, and the top end of the second bolt is threadedly connected to the inside of the bottom shell through the second screw hole, and the mounting bracket is threadedly connected to the bottom end of the bottom shell through the second screw hole and the second bolt. Due to the existence of the mounting bracket, the mounting bracket can effectively support the bottom end of the bottom shell, and the opening of the strip-shaped opening can facilitate normal ventilation of the vent. When the mounting bracket needs to be disassembled, the user can screw the second bolt out of the second screw hole, thereby achieving the purpose of facilitating the user to disassemble and assemble the mounting bracket.

[0014] As a preferred technical solution, a rubber pad is fixedly connected to the inner bottom end of the bottom shell, the vent is located on the inner side of the rubber pad, and the top of the rubber pad is located in contact with the bottom end of the mounting plate. Due to the presence of the rubber pad, the rubber pad has a good anti-slip and shock-absorbing effect, thereby preventing the mounting plate from being bumped when moving downward, and can also effectively provide shock-absorbing and buffering functions for the bottom end of the mounting plate.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] First, when in use, the top cover and the protective shell can effectively protect the workpiece on the top of the mounting plate, and the spring seat can facilitate the up and down shaking of the mounting plate. When the top cover needs to be removed to check or maintain the workpiece on the mounting plate, the user can directly pull the top cover through the sliding principle. When the top cover is pulled, the bottom corner of the top cover will slide along the inclined surface of the protrusion. Affected by the inclined surface, the protrusion will be pressed downward, and the protrusion can drive the mounting plate to be pressed downward together, thereby avoiding the collision between the workpiece on the top of the mounting plate and the bottom of the top cover. The top cover can be directly removed through the sliding principle, thereby achieving the purpose of convenient disassembly and assembly of the top cover. While facilitating the disassembly and assembly of the top cover, it also effectively improves the maintenance efficiency of the workpiece on the top of the mounting plate in the later stage.

[0017] Secondly, due to the opening of the vents, the interior of the bottom shell can be effectively ventilated, thereby improving the heat dissipation effect of the bottom shell itself. When the workpiece on the top of the mounting plate releases heat, the heat can be effectively discharged through the vents, which can effectively increase the service life of the workpiece itself. The filter plate can effectively filter the air flowing through the vents, and can also protect the inside of the vents. The dust cloth can block a large amount of dust and pollutants in the air, thereby preventing dust or pollutants from entering the interior of the bottom shell through the vents and causing harm to the workpiece. Because the dust cloth is attached to the bottom of the filter plate with a Velcro hook, when removing the dust cloth, you can directly tear it off, which is also convenient for the user to replace the dust cloth later.

The top of the bottom shell 1 is slidably connected to a top cover 11, and the top cover 11 covers the top of the bottom shell 1. A protrusion 9 is fixedly connected to the top of the mounting plate 4, and the shape of the top of the protrusion 9 is an inclined surface. The top of the protrusion 9 is in contact with the bottom of the top cover 11. A circular hole 12 is opened at the bottom of the top cover 11, and the position of the circular hole 12 is symmetrical with the position of the transmitter 6. The top end is threadedly connected with a connecting plate 14, and a protective shell 15 is installed on the top end of the connecting plate 14. The transmitter 6 is located on the inner side of the protective shell 15. The bottom end of the bottom shell 1 is threadedly connected with a mounting frame 25. A strip opening 26 is opened on one side of the mounting frame 25, and the strip opening 26 runs through the mounting frame 25. The infrared electric switch mainly consists of three parts: a transmitter 6, a receiver 7 and a detection circuit 8. The main task of the transmitter 6 is to aim at the target and emit light beams. These light beams usually come from light-emitting diodes or laser diodes. The light beams can be emitted continuously or with varying pulse widths. During the emission process, the radiation intensity of these light beams is selected multiple times, and then they run toward the target. The receiver 7 is composed of a photoelectric diode. The infrared switch is composed of a transistor or a phototransistor, and optical elements such as a lens and an aperture are installed in front of it. The task of the receiver 7 is to receive the infrared light emitted by the transmitter 6 and reflected by the target. The detection circuit 8 is located behind the receiver 7. Its main task is to filter out the effective signal and apply the signal. When the receiver 7 receives infrared light of sufficient intensity, the detection circuit 8 will output an electrical signal, which can be used to control the on and off of the switch. In addition, the infrared switch also includes a power supply circuit for providing a stable power supply for the entire system, and a switch control circuit for controlling the on and off of the switch according to the received signal. When in use, the top cover 11 and the protective shell 15 can be used to control the workpiece on the top of the mounting plate 4. Effective protection can effectively improve the safety and service life of the transmitter 6 itself. Due to the presence of the spring seat 2, the spring seat 2 can facilitate the up and down shaking of the mounting plate 4. When the top cover 11 needs to be removed to check or maintain the workpiece on the mounting plate 4, the user can directly pull the top cover 11 through the sliding principle. When the top cover 11 is pulled, the bottom corner of the top cover 11 will slide along the inclined surface of the top of the protrusion 9. Affected by the inclined surface, the protrusion 9 will be pressed downward accordingly. The protrusion 9 can drive the mounting plate 4 to be pressed downward together, thereby avoiding the workpiece on the top of the mounting plate 4 from colliding with the bottom of the top cover 11. The top cover 11 can be directly removed through the sliding principle.

The filter plate 22 can effectively filter the air flowing through the vents 21, and can also protect the inside of the vents 21. The dustproof cloth 24 can block a large amount of dust and pollutants in the air, thereby preventing dust or pollutants from entering the interior of the bottom case 1 through the vents 21 and causing harm to the workpiece. Because the dustproof cloth 24 is attached to the bottom end of the filter plate 22 by the Velcro hook surface 23, when removing the dustproof cloth 24, it can be directly torn off, so it is also convenient for the user to replace the dustproof cloth 24 later.
