Description

Technical Field

[0001] This application relates to the field of smoke detector technology, and in particular to a linear beam smoke fire detector with an obliquely placed circuit board. Background Technology

[0002] Smoke detectors are installed at a high position, and if their indicator lights and operation buttons are set downwards or forwards, they are not easy to observe and operate. Later, a technical solution was developed in which the indicator lights and operation buttons are tilted downwards. However, in this solution, the circuit board is fixed to the housing by screws, which requires the screw posts and screw holes to be tilted. Because the draft direction at this position is tilted, it is necessary to add inclined ejectors and slides, which increases the difficulty of mold manufacturing. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a linear beam smoke detector with an obliquely positioned circuit board.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A linear beam smoke detector with an obliquely positioned circuit board, comprising:

[0006] A base, used to fix it to the wall;

[0007] The circuit board is equipped with indicator lights and button units;

[0008] The inner shell is detachably connected to the base and is provided with a mounting bracket for supporting the circuit board tilted downwards.

[0009] The outer casing is detachably connected to the inner casing; the outer casing is provided with an indicator panel that is tilted downwards corresponding to the circuit board, and a through hole provided on the indicator panel for the button unit to be exposed;

[0010] The mounting bracket includes an L-shaped lower bracket and an upper bracket. The lower bracket extends downward and then forward to support the lower end of the circuit board. The upper bracket extends forward and then downward to restrict the downward movement of the circuit board. The circuit board is secured between the upper bracket and the lower bracket.

[0011] As described above, a linear beam smoke detector with an obliquely placed circuit board has a central support on its inner shell and a limiting groove on its circuit board. After the central support is inserted laterally into the limiting groove, it restricts the circuit board from flipping downwards.

[0012] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the central support includes a back frame in the shape of a right trapezoid, the oblique side of which is used to support the back of the circuit board.

[0013] As described above, in a linear beam smoke detector with a circuit board placed at an angle, the central support includes a limiting frame extending forward from the bottom of the inclined side, forming a limiting portion between the limiting frame and the inclined side. After passing through the limiting groove, the limiting frame, together with the back frame, clamps the circuit board.

[0014] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the two lower brackets are located on both sides of the circuit board, and the upper bracket is located in the middle of the circuit board. The three brackets are arranged in a triangular shape to fix the circuit board.

[0015] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the button unit includes a switch module disposed on the circuit board and a button for triggering the switch module. The button moves along the exposed through hole and in a direction perpendicular to the circuit board.

[0016] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the button includes a body extending at both ends along the direction of the indicator panel and upward, respectively, and a button cap disposed on one end of the body and corresponding to the switch module.

[0017] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the button further includes a limiting cap located at the other end of the main body, and a limiting post is provided on the inner side of the housing, with the limiting cap sleeved on the limiting post.

[0018] As described above, in a linear beam smoke detector with an obliquely placed circuit board, the limiting cap has an inner cavity so that when the button is moved, the limiting post moves relative to the inner cavity.

[0019] The beneficial effects of this application are:

[0020] This invention provides a linear beam smoke detector with an angled circuit board. By using an upper and lower bracket to hold the circuit board in place, screw posts are avoided, reducing installation steps and simplifying the mold structure, making it easier to manufacture. The downward-sloping indicator panel makes it easier to observe the indicator lights and operate the button unit. Attached Figure Description
