Description

Technical Field

[0001] This utility model relates to the field of moisture determination technology, and in particular to a furnace heat dissipation device and a moisture meter. Background Technology

[0002] A moisture meter, also known as a moisture analyzer, is an instrument used to detect the moisture content in a sample. Currently, after completing a test, existing instruments require the furnace lid to be manually opened to allow the furnace to cool naturally to room temperature. The main problem with this method is the long cooling time, resulting in very low efficiency for continuous sample measurement.

[0003] Each time a sample is completed, the furnace needs to be opened manually in a timely manner. When there are no test personnel on site, the furnace cools down more slowly. No cold air enters the furnace and the interior is always kept in a heat preservation state, which leads to a longer cooling time and lower efficiency. Utility Model Content

[0004] To address the technical problems in the prior art, this utility model provides a furnace heat dissipation device and a moisture meter that can achieve rapid cooling of the furnace.

[0005] A furnace cooling device for dissipating heat from the furnace of a moisture meter, comprising: Air inlet cavity, which is connected to the furnace chamber; An air guide mechanism, which is located below the air inlet cavity and is connected to the air inlet cavity; A blower, connected to an air guide mechanism, is used to blow air from outside the furnace into the furnace through the air inlet chamber via the air guide mechanism.

[0006] Preferably, it also includes a sealing mechanism for sealing the air inlet cavity to prevent air blown in by the blower from entering the furnace.

[0007] Preferably, the air inlet cavity has an opening at the bottom, and the sealing mechanism includes a sealing door and a driving mechanism. The driving mechanism is connected to the sealing door and is used to drive the sealing door to switch between a sealed state and an open state. In the sealed state, the sealing door seals the opening, and in the open state, the sealing door does not seal the opening.

[0008] Preferably, it also includes a control mechanism, which is connected to the drive mechanism and the fan, and is used to control the operation of the drive mechanism and the fan so that the sealing door automatically opens and the fan starts after the test.

[0009] Preferably, the driving mechanism includes an electromagnet and a magnetic link. The magnetic link is connected to the sealing door. The electromagnet moves the magnetic link by switching the power on and off, which in turn moves the sealing door, allowing the sealing door to switch between a sealed state and an open state.

[0010] Preferably, the air guiding mechanism includes an upper shell, a lower shell, a left shell, a right shell, a front shell, and a rear shell, which together form a cavity.

[0011] Preferably, the fan is installed in the air guide mechanism.

[0012] Preferably, the air guide mechanism has multiple air inlets near the fan location.

[0013] Preferably, the air inlet cavity is vertically mounted on the upper housing, the electromagnet is vertically mounted on the lower housing, and the magnetic connecting rod extends downward into the cavity of the air guiding mechanism and is opposite to the electromagnet.

[0014] A moisture meter, comprising: The main body has a furnace chamber on its upper surface and an outer shell around its perimeter; The upper cover is pivotally connected to the main body and can be opened or closed with the main body; The main body is also equipped with a furnace heat dissipation device as described above, and the outer shell has multiple through holes near the fan, allowing outside air to enter the air guide mechanism through the through holes under the action of the fan.

[0021] like Figures 1 to 5 As shown, this utility model embodiment provides a moisture meter, which includes: Main body 1, with a furnace chamber 11 on the upper surface of the main body 1 and an outer shell 12 around it; The upper cover 2 is pivotally connected to the main body 1 and can be opened or closed with the main body 1. The main body 1 is also equipped with a furnace heat dissipation device for dissipating heat from the furnace 11 of the moisture meter.

[0022] The furnace cooling system includes: Air inlet chamber 13, which is connected to furnace chamber 11, has an opening at the bottom (unnumbered). Air guide mechanism 14 is located below and connected to air inlet cavity 13; The blower 15 is connected to the air guide mechanism 14 and is used to blow air from outside the furnace 11 into the furnace 11 through the air inlet chamber 13 via the air guide mechanism 14.

[0023] In this embodiment, the furnace heat dissipation device further includes a sealing mechanism for sealing the air inlet cavity 13 to prevent air blown in by the fan 15 from entering the furnace 11. The sealing mechanism includes a sealing door 16 and a driving mechanism. The sealing door 16 is located in the air inlet cavity. The driving mechanism is connected to the sealing door 16 to drive the sealing door 16 to switch between a sealed state and an open state. In the sealed state, the sealing door 16 seals the opening; in the open state, the sealing door 16 does not seal the opening. In this embodiment, the driving mechanism includes an electromagnet 17 and a magnetic connecting rod 18. The magnetic connecting rod 18 can be attracted by the energized electromagnet 17, is connected to the sealing door 16, and passes downward through the opening into the air guiding mechanism 14. By switching the electromagnet 17 on and off, the magnetic connecting rod 18 moves, thereby driving the sealing door 16 to move, so that the sealing door 16 switches between a sealed state and an open state.

[0024] In this embodiment, the furnace heat dissipation device also includes a control mechanism (not shown). The control mechanism connects the drive mechanism and the fan 15, and is used to control the operation of the drive mechanism and the fan 15, so that the sealing door 16 automatically opens and the fan 15 starts after the test. The control mechanism can adopt a single-chip microcomputer structure, and the control logic can be set by instructions. This is a common method, so it will not be described in detail here.

[0025] In this embodiment, the air guiding mechanism 14 includes an upper housing 141, a lower housing 142, a left housing 143, a right housing 144, a front housing 145, and a rear housing 146. The upper housing, lower housing 142, left housing 143, right housing 144, front housing 145, and rear housing 146 form a cavity. A fan 15 is installed in the air guiding mechanism 14. The air guiding mechanism 14 has multiple air inlets (not shown) near the position of the fan 15.

[0026] In this embodiment, the air inlet cavity 13 is vertically mounted on the upper housing 141, the electromagnet 17 is vertically mounted on the lower housing 142, and the magnetic connecting rod 18 extends downward into the cavity of the air guiding mechanism 14 and is opposite to the electromagnet 17.

[0027] In this embodiment, the outer casing 12 is provided with a plurality of through holes 121 near the fan 15, so that outside air can enter the air guide mechanism 14 through the through holes 121 under the action of the fan 15.

[0028] In this embodiment, during the operation of the moisture meter, the sealing door 16 of the air inlet chamber 13 is closed, preventing hot air from flowing through and effectively ensuring uniform temperature in the furnace 11. After the moisture meter finishes operation, the sealing door 16 automatically opens, and the fan 15 automatically starts, drawing cool air from outside into the instrument at high speed through the air duct. This rapidly cools the interior of the furnace 11, allowing the next test to proceed once the internal temperature reaches ambient temperature. This device ensures both uniform temperature within the furnace 11 and rapid cooling, significantly improving work efficiency.

[0029] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
