[0036] Infrared detectors work by detecting infrared rays emitted by objects (such as humans, animals, and moving vehicles) through infrared detection heads. Infrared detectors can detect the activity status of objects at a certain distance and generate various alarms or event upload platforms after data collection and processing. They can be used in application scenarios such as intelligent security protection and elderly care monitoring.

[0037] In related technologies, different use cases require different detection ranges, and the detection range of infrared detectors is closely related to the shielding range of the cover. Therefore, in order to adapt infrared detectors to various use cases, the cover is designed to be detachable so that it can be replaced, making the infrared detector adaptable to various use cases. However, after the infrared detector is installed, it is quite troublesome to replace the cover. The infrared detector needs to be removed from the ceiling or equipment, and then the cover is unscrewed and replaced, which is inefficient.

[0038] In view of the above problems, an embodiment of the present application provides a detector to solve the technical problem of low replacement efficiency of a cover in the detector.

[0039] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0040] Please refer to Figure 2 and Figure 3 An embodiment of the present application provides a detector, including a main body component 1, a sensing component 2 and a cover 3.

[0041] The main body component 1 has a receiving hole 121, and a support block 11 is provided on the main body component 1; the sensing component 2 is arranged in the receiving hole 121; the blocking cover 3 is provided with a receiving groove 33, the main body component 1 is inserted into the receiving groove 33 along the first direction and the main body component 1 and the blocking cover 3 are snap-fitted together, the bottom wall of the receiving groove 33 covers the opening of the receiving hole 121, and the blocking cover 3 is provided with a prying groove 321, which passes through the side wall of the receiving groove 33, and the support block 11 is located in the prying groove 321, and a gap is provided between the surface of the support block 11 facing the first direction and the inner wall surface of the prying groove 321 facing away from the first direction.

[0042] Compared with the threaded connection between the baffle 3 and the main body component 1 in the related art, the baffle 3 in the detector provided by the present application is snap-connected with the main body component 1, which can simplify the steps of connecting the baffle 3 and the main body component 1 to improve the assembly efficiency of the baffle 3 and the main body component 1; after the baffle 3 is snap-connected with the main body component 1, the support block 11 is pried into the slot 321. When disassembling the detector, a rod-shaped object such as a screwdriver is inserted into the prying slot 321, and then the screwdriver or other rod-shaped object is tilted with the support block 11 as a fulcrum so that the end of the screwdriver or other rod-shaped object is against the baffle 3, so that the baffle 3 can be pried, so that the baffle 3 moves relative to the main body component 1 to remove the baffle 3 from the main body component 1, which can simplify the steps of disassembling the baffle 3 and the main body component 1 to improve the disassembly efficiency of the baffle 3 and the main body component 1; thereby solving the technical problem of low replacement efficiency of the baffle 3.

[0043] It should be noted that the first direction is the X direction in the figure.

[0044] Please refer to Figure 2 In some embodiments, the prying groove 321 passes through the side wall of the receiving groove 33, and the direction of the notch of the prying groove 321 is opposite to the first direction. When the cover 3 is engaged with the main assembly 1, the support block 11 is accommodated in the prying groove 321 through the notch of the prying groove 321. The support block 11 and the prying groove 321 can enclose to form a prying hole for inserting a rod-shaped object such as a screwdriver. In this embodiment, after the cover 3 is engaged with the main assembly 1, the support block 11 is flush with the notch of the prying groove 321, or the support block 11 is recessed in the prying groove 321, which can prevent the support block 11 from occupying additional space and make the structure of the detector more compact.

[0045] Please refer to Figure 3 In some embodiments, in a direction away from the axis of the accommodating hole 121, the support block 11 includes a supporting portion 111 and a avoiding portion 112 distributed in sequence, and the end of the avoiding portion 112 away from the supporting portion 111 is inclined in a direction opposite to the first direction.

[0046] Through the above-mentioned arrangement, the supporting portion 111 can serve as a fulcrum for a rod-shaped object such as a screwdriver, and the avoiding portion 112 can avoid tilted rod-shaped objects such as a screwdriver, reserving sufficient space for rod-shaped objects such as a screwdriver, so that rod-shaped objects such as a screwdriver can have a larger tilt angle, so that the end of the rod-shaped object such as a screwdriver drives the blocking cover 3 to move a larger distance relative to the main assembly 1, so as to release the connection structure between the blocking cover 3 and the main assembly 1 and remove the blocking cover 3 from the main assembly 1.

[0047] Please refer to Figure 3 and Figure 4In some embodiments, a first clamping structure 322 is provided on the inner wall of the accommodating groove 33, and a second clamping structure 122 is provided on the outer wall of the main body component 1, and the first clamping structure 322 and the second clamping structure 122 are clamped to each other.

[0048] When assembling the cover 3 and the main body component 1, align the notch of the accommodating groove 33 with the main body component 1, and then move the cover 3 in the direction opposite to the first direction to approach the main body component 1, so that the bottom wall of the accommodating groove 33 covers the opening of the accommodating hole 121, and the first clamping structure 322 and the second clamping structure 122 can be clamped.

[0049] Please refer to Figure 3 and Figure 4 In some embodiments, the first engaging structure 322 is a block, and the second engaging structure 122 is a slot, with the slot opening facing the inner wall of the accommodating groove 33 .

[0050] In the above embodiment, the card block is accommodated in the card slot to connect the cover 3 and the main body component 1; the card block is detached from the card slot to separate the cover 3 and the main body component 1 to simplify the connection structure of the cover 3 and the main body component 1.

[0051] Please refer to Figure 3 In some embodiments, the main body component 1 has a guide slope 123 facing the bottom wall of the accommodating groove 33, and in the first direction, the guide slope 123 is located on one side of the card slot; in the direction away from the axis of the accommodating hole 121, the guide slope 123 has a first end and a second end arranged in sequence, the second end is located on the side of the first end close to the card slot, and the second end is flush with the notch of the card slot.

[0052] In the above embodiment, when the blocking cover 3 and the main body assembly 1 are assembled, the blocking block first contacts the guide slope 123 during the movement of the blocking cover 3 in the direction opposite to the first direction. As the blocking cover 3 moves, the blocking block slides relative to the guide slope 123, and the guide slope 123 helps the blocking block enter the slot.

[0053] Please refer to Figure 4 In some embodiments, the surface of the block facing away from the inner wall of the accommodating groove 33 is a curved surface convex toward the accommodating groove 33 .

[0054] Through the above-mentioned setting, the card block is in linear contact with the main component 1 to reduce the contact area between the card block and the main component 1, thereby reducing the friction between the card block and the main component 1, so as to facilitate the installation of the baffle cover 3 on the main component 1 and the removal of the baffle cover 3 from the main component 1.

[0055] Please refer to Figure 4, in some embodiments, the retaining cover 3 includes a shielding portion 31 and a connecting portion 32. The connecting portion 32 is connected to the shielding portion 31, and the connecting portion 32 and the shielding portion 31 enclose a receiving groove 33. The shielding portion 31 covers the aperture of the receiving hole 121, the connecting portion 32 surrounds the outer peripheral side of the main body assembly 1, a pry groove 321 is formed on the connecting portion 32, and a support block 11 is provided on the outer wall surface of the main body assembly 1.

[0056] In the above embodiment, the pry groove 321 is formed on the connecting portion 32 and communicates with the receiving groove 33. When a rod-shaped object such as a screwdriver is inserted into the pry groove 321, the end of the rod-shaped object such as a screwdriver can enter the receiving groove 33, and the end of the rod-shaped object such as a screwdriver can abut against the shielding portion 31 to prevent the rod-shaped object such as a screwdriver from disengaging from the pry groove 321.

[0057] And, please refer to Figure 3 and Figure 4 , in the above embodiment, the connecting portion 32 surrounds the outer peripheral side of the main body assembly 1. There are multiple first clamping structures 322, and the multiple first clamping structures 322 are distributed at intervals along the circumferential direction of the receiving hole 121. There are also multiple second clamping structures 122, and the second clamping structures 122 are arranged corresponding to the first clamping structures 322 one by one, which can enhance the stability of the connection structure between the retaining cover 3 and the main body assembly 1.

[0058] Optionally, the multiple first clamping structures 322 are evenly distributed along the circumferential direction of the receiving hole 121, which can make the connection structure between the retaining cover 3 and the main body assembly 1 more stable.

[0059] Please refer to Figure 6 , in some embodiments, a first through hole 34 is provided on the retaining cover 3. The sensing component 2 includes a circuit board 21, a sensor 22 and a lens 23. The circuit board 21 is arranged in the receiving hole 121, and both the sensor 22 and the lens 23 are arranged on the circuit board 21. The sensor 22 is located on the side of the circuit board 21 close to the aperture of the receiving hole 121, the lens 23 covers the sensor 22, and the lens 23 passes through the retaining cover 3 through the first through hole 34.

[0060] In the above embodiment, an integral detector can sense whether there are objects such as a human body, an animal, or a running vehicle nearby through the sensor 22.

[0061] Setting the lens 23 can adjust the infrared light sensing of the sensor, making it easier for the sensor to sense the presence of objects such as a human body, an animal, or a running vehicle. Through the lens 23, the infrared sensing angle of the sensor 22 can be increased, thereby increasing the sensitivity of the sensor 22. Various different lenses 23 can be selected according to requirements, for example, a lens 23 with a large sensing range or a small sensing range can be selected.

[0062] The shielding range of the shielding cover 3 is closely related to the aperture of the first through hole 34 on the shielding cover 3. The shielding cover 3 with different apertures of the first through hole 34 can be made according to requirements, so that the detector can be adapted to different usage scenarios.

[0063] Please refer to Figure 6 , in some embodiments, the detector further includes a cover plate 4. The cover plate 4 is connected to the main body assembly 1, and the cover plate 4 covers the hole opening of the accommodating hole 121. The cover plate 4 is provided with a second through hole 41 coaxially arranged with the first through hole 34.

[0064] In the above embodiment, the cover plate 4 can press and fix the circuit board 21 and the lens 23 in the accommodating hole 121, so as to fix the sensing component 2 in the main body assembly 1.

[0065] Please refer to Figure 5 and Figure 6 , an installation post 124 is provided in the accommodating hole 121. A threaded hole 1241 is provided on the installation post 124. The circuit board 21 is sleeved on the installation post 124. The detector further includes a screw (not shown in the figure). The screw passes through the cover plate 4 and is threadedly connected in the accommodating hole 121, so as to press and fix the circuit board 21 and the lens 23 in the accommodating hole 121.

[0066] Please refer to Figure 5 and Figure 6 , the installation post 124 is arranged at the bottom of the accommodating hole 121. Reinforcing ribs 125 are provided in the accommodating hole 121. The reinforcing ribs 125 are respectively connected between the installation post 124 and the side wall of the accommodating hole 121, so as to make the structure of the installation post 124 more stable.

[0067] Please refer to Figure 1 and Figure 6 , in some embodiments, the detector further includes a connecting wire 5 and a power supply component 6. One end of the connecting wire 5 is plugged into the circuit board 21, and the other end of the connecting wire 5 is electrically connected to the power supply component 6.

[0068] Please refer to Figure 4 , a through hole 126 is opened at the bottom of the accommodating hole 121. The connecting wire 5 passes through the through hole 126 and is plugged into the circuit board 21.

[0069] When the detector is installed on the ceiling or the wall, an installation hole is opened on the ceiling or the wall. The main body assembly 1 is snap-fitted in the installation hole, and the power supply component 6 and the connection are located in the installation hole.

[0070] Please refer to Figure 3The main assembly 1 includes a main member 12 and an elastic member 13. The receiving hole 121 is formed on the main member 12. The elastic member 13 is located on the side of the main member 12 that is away from the axis of the receiving hole 121. The elastic member 13 is fixed to the main member 12, and there is a certain distance between the elastic member 13 and the outer wall of the main member 12. When the main assembly 1 is clamped into the mounting hole, pressure is applied to the elastic member 13 in a direction toward the main member 12, so that the elastic member 13 can approach the main member 12, thereby reducing the width of the main assembly 1 in the radial direction of the mounting hole and allowing the main assembly 1 to enter the mounting hole. After the pressure applied to the elastic member 13 is removed, the elastic member 13 returns to its original state under the action of its own elastic force, so that the elastic member 13 can abut against the hole wall of the mounting hole to fix the main assembly 1 in the mounting hole.
