Abstract
Description
Technical Field
[0001] The present application relates to the technical field of smoke detection, and in particular to a vertical support structure of a smoke detector, a smoke chamber structure and a smoke detector. Background Art
[0002] At present, in order to install the transmitting light source and the receiver in the smoke detector to form a smoke detection area in the smoke detector, most smoke detectors will set a horizontal bracket inside the smoke chamber of the smoke detector to install the transmitting light source and the receiver. After installation, the transmitting light source and the receiver are flat on the horizontal bracket, so that the smoke detection area is on the same plane as the transmitting light source and the receiver. When the smoke detector performs smoke detection, when the smoke particles from the outside enter the smoke detector area, they will be blocked by the transmitting light source and the receiver, causing the smoke detector to be unable to detect the incoming smoke in time, resulting in poor smoke detection performance of the smoke detector.

[0030] Example
[0031] See also Figure 1 A schematic diagram of a vertical support structure of a smoke detector is shown in FIG. Figure 2 The cross-sectional view of the vertical support structure of the smoke detector without the light source and the receiver installed is shown in FIG. Figure 3 The structural diagram of the vertical bracket shown in FIG. Figure 4 The cross-sectional view of the vertical support structure of the smoke detector with the transmitting light source and the receiver installed as shown in FIG. Figure 5The side view of the vertical support structure of the smoke detector is shown. This embodiment provides a vertical support structure of the smoke detector, including: a vertical support 2, a circuit board 4, an emitting light source 1 and a receiver 3.
[0032] The vertical bracket 2 is fixed on the circuit board 4 .
[0033] The vertical bracket 2 is provided with a first mounting hole 21 and a second mounting hole 22 on both sides thereof; the extending direction of the first mounting hole 21 and the extending direction of the second mounting hole 22 form an angle with the horizontal direction respectively.
[0034] The emitting light source 1 is fixed in the first mounting hole 21 ; the receiver 3 is fixed in the second mounting hole 22 .
[0035] The emitting light source 1 fixed in the first mounting hole 21 and the receiver 3 fixed in the second mounting hole 22 are both facing upward of the vertical bracket, so that a smoke detection area is formed above the vertical bracket 2 .
[0036] The angle formed between the extension direction of the first mounting hole 21 and the horizontal direction is the same as the angle formed between the extension direction of the second mounting hole 22 and the horizontal direction.
[0037] An included angle formed between an extending direction of the first mounting hole 21 and an extending direction of the second mounting hole 22 is an obtuse angle.
[0038] In the vertical bracket structure of the smoke detector proposed in this embodiment, the first mounting hole 21 and the second mounting hole 22 are both inert holes; one end of the first mounting hole 21 is located on one side of the vertical bracket 2, and the other end of the first mounting hole 22 is located on the top surface of the vertical bracket 2; one end of the second mounting hole 21 is located on the other side of the vertical bracket 2, and the other end of the second mounting hole 22 is located on the top surface of the vertical bracket 2.
[0039] A plurality of tooth structures 23 are disposed at one end of the second mounting hole 22 located on the top surface of the vertical bracket 2 ; each tooth structure 23 of the plurality of tooth structures 23 is vertically disposed at one end of the second mounting hole 22 located on the top surface of the vertical bracket 2 .
[0040] Optionally, in each tooth-like structure 23 , adjacent tooth-like structures 23 and the inner side wall of the second mounting hole 22 in contact with each other form a dust-proof groove.
[0041] In one embodiment, the tooth-like structure 23 can be replaced by various plate-like structures, which will not be described in detail here.
[0042] The emitting light source 1 is provided with a first fixing pin 11, and the receiver 3 is provided with a second fixing pin 31; the emitting light source 1 is fixed to the circuit board 4 through the first fixing pin 11; the receiver 3 is fixed to the circuit board 4 through the second fixing pin 31; by fixing the emitting light source 1 and the receiver 3 on the circuit board 4, the vertical bracket is fixed to the circuit board.
[0043] Specifically, the emitting light source 1 is fixed on the circuit board 4 by welding the first fixing pin 11 ; the receiver 3 is fixed on the circuit board 4 by welding the second fixing pin 31 .
[0044] like Figures 1 to 5 As shown, the vertical bracket 2 is an inverted “concave” structure; after the vertical bracket 2 is fixed on the circuit board 4, an accommodating space 5 is formed between the vertical bracket 2 and the circuit board 4.
[0045] The electronic components on the circuit board 4 are all placed in the accommodating space 5 .
[0046] From the above description, it can be seen that after the vertical bracket 2 is fixed on the circuit board 4, a receiving space 5 is formed between the vertical bracket 2 and the circuit board 4, thereby allowing the circuit board 4 to arrange more electronic components in the receiving space 5, thereby achieving the purpose of reducing the overall size of the device 4.
[0047] The vertical support structure of the smoke detector proposed in this embodiment further includes: a top baffle 6 ; the top baffle 6 is respectively fixed to the two ends of the top surface of the vertical support 2 .
[0048] The setting direction of the top baffle plate 6 located on one side of the emitting light source 1 is consistent with the extension direction of the first mounting hole 21 ; the setting direction of the top baffle plate 6 located on one side of the receiver 3 is consistent with the extension direction of the first mounting hole 21 .
[0049] The vertical support structure of the smoke detector proposed in this embodiment further includes: side baffles 7 ; the side baffles 7 are respectively arranged on both sides of the vertical support 2 .
[0050] In one embodiment, the side baffle 7 is in a triangular shape and is integrally formed with the sides of the vertical bracket 2 .
[0051] From the above description, it can be known that by fixing the top baffle 6 at both ends of the top surface of the vertical bracket 2 and respectively providing side baffles 7 on both sides of the vertical bracket 2, it is possible to prevent external light from entering the emitting light source 1 and the receiver 3, thereby reducing the influence of external light on the emitting light source 1 and the receiver 3.
[0052] In one embodiment, the light source 1 and the receiver 2 are both light emitting diodes.
[0053] This embodiment also provides a smoke chamber structure of a smoke detector, including: the above-mentioned vertical support structure of the smoke detector.
[0054] This embodiment also provides a smoke detector, including: the above-mentioned smoke detector smoke chamber structure.
[0055] The present embodiment proposes a vertical bracket structure, a smoke chamber structure and a smoke detector for a smoke detector. A vertical bracket is used in the vertical bracket structure of the smoke detector. The transmitting light source and the receiver can be fixed on the vertical bracket to form a transmitting and receiving component, and then the transmitting and receiving component is fixed on the circuit board by welding. There is a toothed structure on the surface of the vertical bracket, which can reflect excess light signals and reduce the impact of excess light signals on the receiver. When external dust enters, it will stay in the dustproof groove formed by adjacent toothed structures, so that the function of the receiver will not be affected by excessive dust accumulation.
[0056] In summary, the present embodiment proposes a vertical bracket structure of a smoke detector, a smoke chamber structure and a smoke detector. In the vertical bracket structure of the smoke detector, the vertical bracket is fixed on a circuit board; a first mounting hole and a second mounting hole are respectively provided on both sides of the vertical bracket; an extension direction of the first mounting hole and an extension direction of the second mounting hole respectively form an angle with a horizontal direction; a transmitting light source is fixed in the first mounting hole; a receiver is fixed in the second mounting hole; the fixed transmitting light source and receiver are both oriented toward the top of the vertical bracket, thereby forming a smoke detection area above the vertical bracket, which is aligned with the corresponding Compared with the method in which the smoke detection area is arranged on the same plane with the light source and the receiver in the related technology, a smoke detection area is formed above the vertical bracket using a vertical bracket having a first mounting hole and a second mounting hole for respectively fixing the light source and the receiver, so that the light source and the receiver are not in the same plane as the smoke detection area, and smoke particles entering the smoke detection area from the outside will no longer be blocked by the light source and the receiver, and smoke particles in any direction can quickly reach the smoke detection area and be detected by the smoke detector, thereby ensuring that the smoke detection performance of the smoke detector is always in the optimal performance state.
[0057] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
