[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] like Figure 1-2 As shown, the present application provides a smoke detection device, comprising a workbench 1, a work station disc 10 is rotatably connected to the center of the surface of the workbench 1, a plurality of inclined wedge blocks 3 are fixedly connected to the surface of the work station disc 10, and the gap between two adjacent inclined wedge blocks 3 constitutes a slot 2 for placing a circular membrane clamp, and the slot 2 can place the circular membrane clamp with a sample;

[0027] An outlet 7 and an inlet 6 are provided on the same side of the workbench 1, and the outlet 7 has a certain slope to facilitate the unloading of the circular film clamp. A baffle 8 is fixedly installed on the workbench 1, and the baffle 8 is arranged above the outlet 7. The baffle 8 is used to squeeze and eject the circular film clamp;

[0028] A detection mechanism is installed on the workbench 1, and the detection mechanism includes a detection device transmitting end 4 and a detection device receiving end 5. The detection device transmitting end 4 is installed on the workbench 1, and the detection device receiving end 5 is installed on a side of the workbench 1 away from the detection device emitting end 4;

[0029] like Figure 1 and Figure 3-5As shown, a limiting hole 101 is provided on the workbench 1 and below the outlet 7, and a placing mechanism 9 is provided on one side of the workbench 1. The placing mechanism 9 is used to temporarily place the circular film clamp ejected by the blocking piece 8. The placing mechanism 9 includes an insertion rod 901 slidably connected to the limiting hole 101. The insertion rod 901 and the limiting hole 101 are detachably installed, which can facilitate personnel to assemble and disassemble according to needs;

[0030] Meanwhile, a first rotating column 902 is fixedly connected to the other end of the insertion rod 901, a first fixed block 903 is rotatably connected to the first rotating column 902, a placement plate 904 is fixedly connected to the first fixed block 903, a second fixed block 905 is fixedly installed on a side of the placement plate 904 close to the insertion rod 901, a second rotating column 916 is rotatably connected to the second fixed block 905, and a fixing rod 906 is fixedly installed on the second rotating column 916;

[0031] A circular rod 907 is movably sleeved on one end of the fixed rod 906, and a base (not shown in the figure) is fixedly installed on the other end of the circular rod 907. The base has a certain weight, and a layer of anti-skid sheet is glued on the lower surface of the base. The anti-skid sheet contacts the ground to increase the friction between the base and the ground.

[0032] Before the equipment is operated, personnel can first insert the insertion rod 901 into the limiting hole 101. When the insertion rod 901 is fully inserted into the limiting hole 101, the placement mechanism 9 and the workbench 1 are assembled. At this time, when the equipment has completed the inspection through the detection mechanism, the circular membrane clamp with the sample will be squeezed and ejected from the outlet 7 by the blocking piece 8, and then fall on the placement plate 904.

[0033] In order to prevent the circular film clip from hitting the inner wall of the placement plate 904 and being easily ejected by the placement plate 904 and falling to the ground, a sponge sheet 910 is glued to the inner wall of the placement plate 904, and the sponge sheet 910 can reduce the buffering force when the circular film clip hits the inner wall of the placement plate 904;

[0034] In order to adjust the inclination angle of the placement plate 904 and to adjust the falling speed of the circular film clamp on the placement plate 904, a threaded rod 908 is threadedly connected to the circular rod 907, and a rotating block 909 is fixedly connected to one end of the bolt rod 908. The rotating block 909 facilitates the rotation of the bolt rod 908. When the overall height of the circular rod 907 and the fixed rod 906 is adjusted, the personnel can rotate the rotating block 909, and the rotating threaded rod 908 squeezes the surface of the fixed rod 906, so that the fixed rod 906 is close to the inner wall of the circular rod 907, thereby completing the position limitation of the fixed rod 906, so that the adjustable fixed rod 906 moves up and down in the circular rod 907, so as to drive one end of the placement plate 904 to rotate along the first rotating column 902, thereby changing the inclination angle of the placement plate 904.

[0035] A rotating rod 911 is rotatably connected to the side of the placement plate 904 close to the outlet 7. When the inclination angle of the placement plate 904 is different, the sliding speed of the circular membrane clamp inside the placement plate 904 is different. At this time, the personnel can adjust the angle of the placement plate 904 according to the needs, and the setting of the rotating rod 911 can facilitate the personnel to rotate the placement plate 904, and prevent the side of the placement plate 904 close to the workbench 1 from being parallel to the workbench 1 when the placement plate 904 is rotated, thereby causing the placement plate 904 to be difficult to rotate.

[0036] like Figure 4 and Figure 5 As shown, the bottom surface of the inner wall of the placement plate 904 is rotatably connected with a plurality of rollers 915. The setting of the rollers 915 can reduce the friction between the ejected circular film clamp and the bottom wall of the placement plate 904, and avoid the circular film clamp stopping in the center of the placement plate 904 due to excessive friction, thereby affecting the moving path of the next ejected circular film clamp;

[0037] Limiting grooves 912 are provided on opposite sides of the inner wall of the placement plate 904 away from the outlet 7, and a baffle 913 is clamped in the limiting groove 912. The baffle 913 has a rectangular block 914 that is adapted to the size of the limiting groove 912. The rectangular block 914 can slide in the limiting groove 912, and the setting of the baffle 913 can intercept the circular membrane clamp to prevent the circular membrane clamp from falling on the ground.

[0038] It is additionally noted that the detachable installation of the baffle plate 913 can make the use of the entire placement mechanism 9 more flexible. For example, the overall tilt angle of the placement plate 904 can be adjusted, so that when the placement plate 904 is separated from the workbench 1, it can be used as a storage place for the circular film clips.

[0039] The placement plate 904 is U-shaped, and the opening range gradually decreases radially. The opening range of the placement plate 904 allows the circular membrane clamps inside the placement plate 904 to be distributed inside the placement plate 904 in a pop-up order, making it convenient for personnel to find the circular membrane clamps after detection.

[0040] To sum up: personnel can place the circular membrane clamp with the sample from the inlet 6 to the slot 2, and the work station disk 10 will drive the slot 2 to rotate. When the slot 2 rotates to the detection device transmitting end 4, the detection device transmitting end 4 and the detection device receiving end 5 will detect the circular membrane clamp. After the detection is completed, the circular membrane clamp will be squeezed out from the outlet 7 by the blocking piece 8. When personnel need to use the placement mechanism 9, personnel can directly insert the insertion rod 901 into the corresponding limiting hole 101, and pull out the fixing rod 906 from the circular rod 907, so as to adjust the height of the placement plate 904. The inclination angle of the placement plate 904 can be adjusted by the cooperation between the rotating column and the fixing block. When personnel do not need to use the mechanism, personnel only need to pull out the insertion rod 901 to complete the disassembly between the mechanism and the equipment. At the same time, this mechanism occupies a small volume and can be easily stored in a corner.

[0041] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
