[0019] like Figure 1 、 Figure 2 As shown, the utility model provides a hot air detection device that simulates the internal working environment of a printer, including a frame 2, an electrical box 1, a fan hood 4, two opposing lamp tube racks 2-2, an air supply pipe group 3 and a blower (not shown in the figure), the lamp tube rack 2-2 is fixed in the frame 2, and the lamp tube rack 2-2 has a power electrode (not shown in the figure) for energizing the lamp tube 5. The frame 2 has a group of mounting brackets 2-1 for hanging the fan hood 4, and the fan hood 4 is located directly above the lamp tube rack 2-2. The cross-section of the fan hood 4 is trapezoidal, and the lower side of the trapezoid is long. A plurality of blowing holes are provided on the bottom surface of the small fan hood 4. The length of the area where the blowing holes are arranged is equivalent to the length of the bottom surface of the air hood, which is equivalent to that the blowing holes are arranged on the bottom surface of the entire air hood 4. The air supply pipe group 3 is connected to the blower, and the air supply port of the air supply pipe group 3 is connected to the air inlet pipe 4-1. The air supply pipe group 3 has a connecting cover 3-1 that corresponds one-to-one to the air inlet pipe 4-1. The connecting cover 3-1 can be buckled on the air inlet pipe 4-1. In order to prevent air leakage, a rubber pad is provided in the connecting cover 3-1 to increase the sealing between the connecting cover 3-1 and the air inlet pipe 4-1. The powered electrode and the blower are electrically connected to the control system in the electrical box 1.

[0020] Mounting brackets 2-1 are located on either side of the hood 4. Mounting brackets 2-1 have mounting plates 2-4 with longitudinal slots. The hood 4 has fixing plates 4-2 corresponding to the mounting plates 2-4. Fixing plates 4-2 have fixing holes. The hood 4 and mounting brackets 2-1 are connected by fixing bolts that pass through the fixing holes and slots. Adjusting the position of the fixing bolts in the slots adjusts the height of the hood 4, thereby varying the distance between the air outlet at the bottom of the hood 4 and the light tube 5.

[0021] Two parallel mounting rods 2-3 are provided in the frame 2. Each lamp tube holder 2-2 spans the two mounting rods 2-3. A plurality of mounting holes are provided at intervals on the mounting rods 2-3. The lamp tube holders 2-2 are connected to the mounting rods 2-3 by bolts passing through the mounting holes. By fixing the lamp tube holders 2-2 to different mounting holes on the mounting rods 2-3, the spacing between the two lamp tube holders 2-2 can be adjusted to accommodate lamp tubes 5 of different lengths.

[0022] like Figure 3 、 Figure 4 As shown, two opposing reflecting plates 6 arranged in an eight-shaped shape are provided on the bottom surface of the wind hood 4, and the length of the reflecting plates 6 is equal to the length of the wind hood 4. A temperature measuring thermocouple 6-1 is provided in the middle position of the outer side surface of the reflecting plate 6, and the temperature measuring thermocouple 6-1 is electrically connected to the controller in the electrical box 1. The blowing holes include an air outlet 4-4 located in the area between the two reflecting plates 6 and a reflecting plate blowing hole 4-3 located above the outer side surfaces of the two reflecting plates 6. The setting of the reflecting plate 6 is used to gather the wind blown out from the blowing hole between the two reflecting plates 6 onto the lamp tube 5, and at the same time prevent the heat from rising when the lamp tube 5 is powered on for heating. The reflecting plate blowing hole 4-3 above the outer side of the reflecting plate 6 is used to cool the reflecting plate 6 so that the heat on the reflecting plate 6 dissipates as soon as possible.

[0023] When the above-mentioned device is in use, the lamp tube 5 is first placed on the lamp tube rack 2-2. At this time, the lamp tube 5 is located directly below the area between the two reflective plates 6. The lead connectors at both ends of the lamp tube 5 are connected to the powered electrodes on the lamp tube rack 2-2, the lamp tube 5 is energized, and the blower is turned on to allow the wind delivered by the blower to enter the wind hood 4 through the air supply pipe group 3. The wind hood 4 gathers the wind and blows it out from the blowing holes at the bottom. The air outlet located between the reflective plates 6 is aimed at the lamp tube 5, and the reflective plate blowing holes 4-3 located outside the reflective plate 6 are aimed at the outer wall of the reflective plate 6. The device simulates the working environment of the lamp tube 5 in the printer copy, which provides assistance for the measurement of the performance of the lamp tube 5 under the working state.

[0024] The above embodiments of the present invention are described in detail.
