DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1-Figure 3 As shown, a bathroom mirror anti-fog testing device proposed in this embodiment includes a speaker cover 1, a cylinder 2, an exhaust mechanism hot air blower 3, a mounting bracket 4 and an atomizer 5.

[0021] The horn cover 1 is made of a transparent material, and the ring of the horn cover 1 has a sealing strip 9; a handle 6 is fixed to the bottom end of the cylinder 2, and the handle 6 has a wavy convex structure on the side adjacent to the horn cover 1; a partition 10 is provided on the inner side of the cylinder 2, and the spaces separated by the two sides of the partition 10 are chamber A201 and chamber B202 respectively, and chamber A201 is connected to the inner cavity of the horn cover 1.

[0022] The exhaust mechanism is installed on the cylinder 2, and is used to exhaust the gas in the horn cover 1 so that the horn cover 1 is adsorbed on the mirror to be tested. The exhaust mechanism includes a sealing piston 11, a piston rod 12, a push plate 13, a connecting pipe 14, a ventilation pipe 15, a one-way valve A16 and a one-way valve B17. The sealing piston 11 is movably arranged on the inner side of the chamber B202. The sealing piston 11 is fixedly connected to the push plate 13 through the piston rod 12. The piston rod 12 movably passes through the end of the cylinder 2. The connecting pipe 14 passes through both ends of the partition 10. The one-way valve A16 is installed on the connecting pipe 14. The ventilation pipe 15 is fixed on the cylinder 2, and its two ends are respectively connected to the chamber B202 and the outside world. The one-way valve B17 is installed on the ventilation pipe 15.

[0023] The mounting bracket 4 is fixed on the barrel 2, and the hot air blower 3 and the atomizer 5 are both mounted on the mounting bracket 4. The output end of the hot air blower 3 is connected to the hot air pipe 301, and the output end of the hot air pipe 301 is connected to the chamber A201. The output end of the mounting bracket 4 is connected to the chamber A201, and its input end is connected to the water pipe 501.

[0024] A temperature sensor 18 and a humidity sensor 19 are installed on the inner side of chamber A201, and a controller 8 is installed on the cylinder 2. The controller 8 is electrically connected to the temperature sensor 18 and the humidity sensor 19. The set temperature sensor 18 and humidity sensor 19 can monitor the temperature and humidity during the test process and feed back the detection signal to the controller 8.

[0025] In this embodiment, when performing the test, the sealing strip 9 is first wetted with water, and then the sealing strip 9 is pressed on the mirror surface to be tested, and then the sealing piston 11 is driven to move repeatedly in the chamber B202. When the sealing piston 11 moves to the side away from the chamber A201, the gas inside the chamber A201 and the horn cover 1 enters the chamber B202 through the connecting pipe 14, and the one-way valve A16 only allows the gas to flow into the chamber B202. When the sealing piston 11 moves to the side adjacent to the chamber A201, the gas in the chamber B202 is discharged through the vent pipe 15, so that the horn cover 1 Negative pressure is formed inside and adsorbed on the mirror surface; then the anti-fog test can be started. During the test, the water pipe 501 is connected to the water source, and the hot air blower 3 and the atomizer 5 are started. The hot air blower 3 blows out hot air into the inner cavity of the speaker cover 1 to simulate the temperature in the bathroom.
