[0020] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0021] This utility model discloses a heat dissipation structure for the main unit of a food purifier, as follows: Figure 1 As shown, the system includes a main unit housing 10, and an oxygen generator 20 (generating tube), a high-voltage transformer 30, an air pump 40, a main control board 50, an electronic speed controller 60, a duct housing 70, and at least one fan disposed within the main unit housing 10. The main unit housing 10 has an air outlet 111 on one side and an air inlet 112 on the other side (either side or opposite side). The at least one fan includes a first fan 81 positioned at the air outlet 111 to force airflow from the main unit housing 10 into the air inlet 112 and out through the air outlet 111. The duct housing 70 extends laterally and is fitted onto the air outlet 111, enclosing the first fan 81. The oxygen generator 20 is disposed within the duct housing 70 and located laterally outside the first fan 81. The high-voltage transformer 30... The main control board 50 is positioned on the outer side of the air inlet end of the air duct housing 70, and the main control board 50 is positioned at the air inlet 112. Thus, under the action of the first fan 81, the externally flowing cold air first passes through the main control board 50, and finally through the high-voltage transformer 30 and the oxygen generator 20. The electronic speed controller 60 and the air pump 40 are positioned on the airflow path between the main control board 50 and the high-voltage transformer 30. By placing the high-voltage transformer 30 and the oxygen generator 20, which generate the most heat, at the end of the airflow path, and placing the main control board 50, which generates less heat and whose performance is more significantly affected by temperature, at the air inlet 112, the heat energy within the main housing housing 10 is distributed in a generally increasing manner along the airflow path. This effectively ensures the heat dissipation performance of the main unit and effectively avoids mutual interference between components, ensuring the stability and reliability of the main unit's operation.
[0022] In this embodiment, specifically as follows: Figure 1 As shown, the main unit casing 10 has an air outlet 111 at the upper end of the left side wall and an air inlet 112 at the lower end of the right side wall. According to the principle that hot air rises and cold air falls, this arrangement is more conducive to the exhaust of hot air. At the same time, the ESC 60 is arranged on the right side of the main control board 50, and the air pump 40 is arranged between the main control board 50 and the high voltage transformer 30. Preferably, the right side wall of the main unit casing 10 is provided with a second air inlet 112 corresponding to the air pump 40. At least one fan also includes a second fan 82 corresponding to the air inlet 112 and the second air inlet 112.
[0023] In this embodiment, as Figure 2As shown, the main unit housing 10 includes a front shell 11 and a rear cover 12 made of sheet metal. The front shell 11 is a thin shell structure with an open rear end. The rear cover 12 is fitted onto the rear end of the front shell 11 to form a mounting cavity. The rear cover 12 is provided with a louver structure and is used to increase the auxiliary air inlet 121 for increasing air intake. The active oxygen generator 20, high-pressure transformer 30, air pump 40, electronic speed controller 60, and air duct housing 70 are all fixedly mounted on the front side panel of the front shell 11. The air inlet 112 and air outlet 111 are respectively located on the left side panel and right side panel of the front shell 11. Preferably... The front side plate of the front shell 11 has a rearwardly raised portion 113 corresponding to the air duct shell 70. The air duct shell 70 is disposed on the raised portion 113 so that the air inlet port of the air duct shell 70 is at least partially exposed on the end face of the high voltage transformer 30. Preferably, the rear end face of the high voltage transformer 30 is located between the front wall and the rear wall of the air inlet port of the air duct shell 70. In this way, by arranging the high voltage transformer 30 next to the air inlet port of the air duct shell 70 and partially blocking the air inlet port, it is possible to ensure that the airflow can be smoothly discharged through the air duct shell 70 while improving the effect of the airflow on the high voltage transformer 30 to improve the heat dissipation performance.
[0024] In this embodiment, as Figure 3 As shown, the ESC 60 has a metal heat sink housing 61, on which a plurality of heat sink fins 611 are provided. The heat sink fins 611 can effectively increase the heat dissipation area to improve the heat dissipation performance of the ESC 60.
[0025] Compared with the prior art, this utility model has a simple and reasonable structure. It forces airflow into the main unit casing by strong suction, and places the high-pressure pack and active oxygen generator, which generate the most heat, at the end of the airflow path. This makes the heat energy in the main unit casing basically increase with the airflow path, which effectively improves the heat dissipation of the main unit and effectively reduces the mutual influence between the components, thus ensuring the stability and reliability of the main unit's operation.
[0026] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
