DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] A device for detecting the smoke point of edible oil comprises a base 1, heating furnaces 2 are respectively installed on both sides of the base 1, when measuring the smoke point, a sample cup of edible oil is placed on the heating furnace 2 for heating, the heating furnace 2 can be built in the base 1, and it is only necessary to expose the heating element of the heating furnace 2; by arranging two heating furnaces 2, two edible oil sample cups can be heated at the same time, and the two heating furnaces 2 can be heated independently.

[0024] A display panel 20 may be installed at the front end of the base 1 , and the display panel 20 may be used to display the temperature detected by the temperature sensor 6 , the heating power and heating time of the heating furnace 2 , and the sensing result of the photoelectric sensor, etc.

[0025] A support frame 3 is installed on the base 1. The support frame 3 is respectively installed with a detection housing 4 on the upper side of the heating furnaces 2 on both sides. A flue 5 is opened in the middle of the detection housing 4. Since the detection housing 4 is directly above the heating furnace 2, the oil smoke generated by the edible oil in the sample cup during the heating process of the heating furnace 2 will enter the flue 5. Since a photoelectric sensor that cooperates with the flue 5 is also installed in the detection housing 4, the photoelectric sensor can detect the oil smoke in the flue 5. The photoelectric sensor and the temperature sensor 6 are both connected to the controller. When the photoelectric sensor detects the oil smoke in the flue 5, it will transmit a signal to the controller. The controller records the oil temperature of the edible oil in the sample cup sensed by the temperature sensor 6 at this time, and displays the oil temperature on the display panel 20. The temperature sensor 6 at the bottom of the detection housing 4 can be inserted into the edible oil in the sample cup to a certain depth to accurately detect the oil temperature of the edible oil in the sample cup.

[0026] The side surface of the support frame 3 close to the detection shell 4 is provided with a slide groove 7, and the slide groove 7 can be set as a T-shaped slide groove 7. The detection shell 4 is installed with a slide rail 8 that cooperates with the slide groove 7. The slide rail 8 is inserted into the slide groove 7, and the detection shell 4 can slide up and down along the slide groove 7 through the slide rail 8. Before the test, we can lift up the detection shell 4 to move the temperature sensor 6 at the bottom of the detection shell 4 upward by a certain distance, and then place the sample cup containing the edible oil sample on the heating furnace 2, and then put the detection shell 4 down until the slide rail 8 contacts the bottom of the slide groove 7. At this time, the temperature sensor 6 is inserted into the sample cup to a certain depth. When the test is completed, lift up the detection shell 4 again.

[0027] The top of the support frame 3 and the detection housing 4 of the utility model are respectively provided with mutually matching plug holes 21, and a plug pin 22 is inserted between the plug hole on the support frame 3 and the plug hole 21 on the detection housing 4, so that the detection housing 4 can be fixed at a higher position of the support frame 3. When no detection is performed, the utility model can fix the detection housing 4 at a higher position of the support frame 3 through the plug pin 22, so that the temperature sensor 6 at the bottom of the detection housing 4 is on the upper side of the edible oil sample cup. When the detection is performed, the plug pin 22 can be removed, which is very convenient and simple.

[0028] A handle 9 is installed on the top of the detection housing 4, so that people can easily lift the detection housing 4 upwards.

[0029] A transparent tube 10 is installed in the flue 5. By installing the transparent tube 10, when the oil smoke enters the smoke pipe, it will pass through the transparent tube 10 and will not directly contact the inner wall of the smoke pipe, which can effectively ensure that the oil stains will not contaminate the photoelectric sensor during long-term use. The detection shell 4 is provided with a material cavity 11 on both sides of the flue 5. The photoelectric sensor includes a light emitter 12 and a receiver 13. The light emitter 12 and the receiver 13 are respectively installed in the material cavity 11 on both sides. The light emitter 12 and the receiver 13 are arranged in a straight line. The transparent tube 10 is between the light emitter 12 and the receiver 13. During detection, the light emitted by the light emitter 12 passes through the transparent tube 10 to reach the receiver 13. When oil smoke enters the transparent tube 10, the receiver 13 detects the oil smoke in the transparent tube 10 and transmits a signal to the controller. The controller then records the temperature of the temperature sensor 6 at this time. The light emitter 12 and the receiver 13 are connected to the controller respectively.

[0030] The transparent tube 10 is in a square shape; a gripping hole 14 is provided on the top of the transparent tube 10 , and the gripping hole 14 is provided to facilitate people to lift the transparent tube 10 upwards.

[0031] The detection housing 4 is provided with a mounting platform 15 at the edge of the bottom of the flue 5. When in use, the transparent tube 10 is placed on the mounting platform 15 and supported by the mounting platform 15. The top surface of the mounting platform 15 is provided with a sealing groove 16 for the transparent tube 10 to be inserted. The transparent tube 10 is inserted into the sealing groove 16, which can effectively prevent oil smoke from entering between the transparent tube 10 and the smoke pipe.

[0032] A smoke collecting hood 17 is installed at the bottom of the detection shell 4. The smoke collecting hood 17 is conical. By setting the smoke collecting hood 17, the smoke generated by the edible oil in the sample cup can enter the transparent tube 10 in the smoke pipe as much as possible, thereby improving the accuracy of detection. The smoke collecting hood 17 rises and falls with the detection shell 4.

[0033] A fixing cylinder 18 is installed at the bottom of the detection shell 4 on the outside of the flue 5. The fixing cylinder 18 is fixed to the detection shell 4 by welding. An internal thread is provided on the fixing cylinder 18. A connecting cylinder 19 is provided on the top of the smoke hood 17. The connecting cylinder 19 has an external thread that matches the fixing cylinder 18. The connecting cylinder 19 is threadedly connected to the fixing cylinder 18, so that the smoke hood 17 can be detachably installed on the detection shell 4, which facilitates the cleaning of the smoke hood 17.
