[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] See also Figures 1 to 5 The utility model provides a portable oil smoke detector calibration device; comprising an oil smoke generating device 1, a pipeline 2, an oil smoke detection standard 3 and an oil smoke detection calibrator 4;

[0016] The front of the oil fume generating device 1 is connected to the box door through a hinge. One end of the pipe 2 is arranged at the top of the oil fume generating device 1 and is connected to the interior thereof. The oil fume detection standard 3 and the oil fume detection calibrator 4 are symmetrically arranged with the pipe 2 and are located at the other end of the pipe 2. An oil fume generating component is provided inside the oil fume generating device 1, and is used in conjunction with the oil fume detection standard 3 and the oil fume detection calibrator 4 through the pipe 2. The other end of the pipe 2 is connected to a butt joint pipe 5 through a clamp, and the other end of the butt joint pipe 5 is connected to a smoke exhaust pipe 6 through a clamp.

[0017] like Figure 1As shown, the surfaces of the oil smoke detection standard 3 and the oil smoke detection calibrator 4 are fixedly connected with auxiliary tubes, the other ends of which are detachably mounted on the surface of the pipe 2. The surface of the butt joint 5 is provided with a docking port for connecting with the auxiliary tube. The butt joint 5 can be spliced with multiple tubes through a clamp to extend the length of the pipe. The purpose of this arrangement is to facilitate the installation of multiple oil smoke detection calibrators 4, so as to facilitate batch detection and calibration and improve calibration efficiency.

[0018] The bottom of the oil smoke detection standard device 3 and the oil smoke detection calibrator 4 can be provided with a support platform for support (such as Figure 1 to maintain stability during use;

[0019] like Figure 1 As shown, one end of the exhaust pipe 6 can be connected to an external filtering device to facilitate filtering of the exhausted oil smoke. A supporting platform (not shown in the figure) can be set at the bottom of the oil smoke generating device 1 to facilitate its support for detection and calibration.

[0020] The oil fume generating assembly includes a furnace lining 7 arranged inside the oil fume generating device 1, an electromagnetic heating plate 19 arranged at the bottom of the furnace lining 7, a heating pot 8 arranged on the top of the electromagnetic heating plate 19, a first peristaltic pump 9 and a second peristaltic pump 10 arranged on the side wall of the furnace lining 7. The peristaltic pump is an existing technology and is only referenced here. The specific structure will not be described in detail.

[0021] An oil storage bottle 11 and a water storage bottle 12 are provided inside the oil fume generating device 1. The sampling ends (referring to oil and water) of the first peristaltic pump 9 and the second peristaltic pump 10 are connected to the oil storage bottle 11 and the water storage bottle 12 through connecting pipe 1 and connecting pipe 2, and the sampling ends (referring to oil and water) extend to the interior of the heating pot 8.

[0022] The furnace lining 7 is detachably mounted inside the oil fume generating device 1. The connecting pipes 1 and 2 at the sampling ends of the first peristaltic pump 9 and the second peristaltic pump 10 penetrate the inner wall of the furnace lining 7 and are connected to the sampling ends (referring to oil and water) at the bottom of the oil storage bottle 11 and the water storage bottle 12. The sampling ends (referring to oil and water) communicating with the oil storage bottle 11 and the water storage bottle 12 are located on the back of the oil fume generating device 1.

[0023] The furnace lining 7 is installed in a detachable manner to facilitate subsequent disassembly and assembly, and to facilitate cleaning of the internal oil smoke.

[0024] The oil and water in the oil storage bottle 11 and the water storage bottle 12 can be extracted by the first peristaltic pump 9 and the second peristaltic pump 10 and injected into the heating pot 8. The oil and water in the heating pot 8 are heated by the electromagnetic heating plate 19 at the bottom of the furnace lining 7. The generated oil fume enters the oil fume detection standard 3 and the oil fume detection calibrator 4 through the pipe 2, which is convenient for the detection and calibration of the oil fume detection calibrator 4.

[0025] A smoke exhaust port connected to the pipe 2 is provided at the top of the furnace lining 7. A fan 13 is provided inside the pipe 2 near the end of the oil fume generating device 1 and inside the smoke exhaust pipe 6. The end of the smoke exhaust pipe 6 away from the docking pipe 5 is connected to a closing cover 14 through a hinge, and a tension spring 15 is provided on the side of the closing cover 14 near the smoke exhaust pipe 6.

[0026] Note: The tension spring 15 uses an elastic coefficient that is smaller than the thrust of the airflow when the fan 13 rotates at a certain speed, so as to avoid the problem that the airflow cannot push the closing cover 14 due to the large elastic coefficient of the tension spring 15.

[0027] like Figure 4 and Figure 5 As shown, there are two closing covers 14 provided at one end of the exhaust pipe 6, which are symmetrically arranged with the vertical center line of the exhaust pipe 6 as the symmetry axis. They can be flipped to the right and left by a hinge connection to facilitate the exhaust of oil smoke.

[0028] Note: Display screen 17 on the side of the oil smoke generating device 1;

[0029] The oil fume generating device 1 is equipped with a sensor and a control module, which can detect the oil fume concentration inside the device, and can control the temperature of the electromagnetic heating plate 19 through the display 17. The control module can also control the amount of water and oil delivered to the heating pot 8 by the first peristaltic pump 9 and the second peristaltic pump 10.

[0030] The oil smoke generating device can be operated through the display screen 17, and can record the concentration, temperature, and amount of oil and water of the oil smoke generated. At the same time, it can be connected to external electronic devices to export relevant records for easy viewing;

[0031] When the oil smoke inside the pipe 2 needs to be discharged, the display screen 17 sends a signal to the control module inside it, thereby controlling the fan 13 to increase its speed. At this time, the closing cover 14 drives the tension spring 15 to open one end of the exhaust pipe 6, allowing the oil smoke to be discharged quickly;

[0032] like Figure 2 As shown, a stirring module is provided on the bracket portion at the top of the heating pot 8, comprising a drive motor provided at the bottom of the bracket and a stirring rod provided at the output end of the drive motor. The purpose of such a configuration is to stir the oil inside the heating pot 8 evenly, which is beneficial to the stability of the smoke concentration.

[0033] A temperature probe is provided on the surface of the top bracket of the heating pot 8, near the stirring module. The temperature detection end thereof extends into the interior of the heating pot 8, and can detect the internal heating temperature, which is convenient for use with the warning light 16.

[0034] A warning light 16 is provided at the edge of the upper surface of the oil fume generating device 1, a display screen 17 is provided on the front near the door, a heat dissipation hole is provided on one side of the oil fume generating device 1, a support frame 18 is provided at the connection between the pipe 2 and the docking pipe 5 and the bottom of the clamp, and a handle rod is provided on the side of the door to facilitate opening the door.

[0035] like Figure 1 and 2 As shown, the warning light 16 is activated according to the temperature limit. When the temperature value is exceeded, the warning light 16 flashes (red and green alternately), thereby alerting the operator that the temperature is too high. A transparent layer is provided on the side of the box door to observe the internal heating situation;

[0036] The support frame 18 adopts a triangular bracket and is an existing technology. It is only cited here and will not be described in detail. The top is retractable, and the connection between the pipe 2 and the butt pipe 5 is fixed by a clamp. The bottom of the clamp is fixedly connected with a screw, and the bottom end of the screw is threadedly connected to the top of the support frame 18. The purpose of this arrangement is to facilitate disassembly at a later time for easy transportation.

[0037] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0038] In the present invention, the working steps of the device are as follows:

[0039] 1. When using, if Figure 1 As shown, the oil fume detection standard 3 and the oil fume detection calibrator 4 are assembled and in working condition. A plurality of connecting pipes 5 can be added and spliced as needed. The connecting pipes 5 are connected to the oil fume detection standard 3 and the oil fume detection calibrator 4 through the connecting ports on the surface thereof. The supporting frame 18 is used to support the pipes and increase the length of the connecting pipe 5 to measure the concentration of oil fume in different positions of the pipes.

[0040] 2. The oil storage bottle 11 and the water storage bottle 12 inside the oil fume generating device 1 store an appropriate amount of oil and water. The display screen 17 controls the first peristaltic pump 9 and the second peristaltic pump 10 to extract the oil and water from the oil storage bottle 11 and inject them into the heating pot 8. At the same time, the electromagnetic heating plate 19 is controlled to heat the heating pot 8, thereby generating oil fume;

[0041] Next, the fan 13 above the furnace lining 7 is controlled to draw the oil smoke into the pipe 2, the docking pipe 5 and the exhaust pipe 6. After the oil smoke is evenly mixed inside the pipe, the test value of the oil smoke detection standard 3 is used as the standard value, thereby completing the calibration of the oil smoke detection calibrator 4.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
