CONSTANT-VOLTAGE POWER SUPPLY MECHANISM OF A LOTTERY TICKET VENDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/242149
Kind Code:
A1
Abstract:
The present application discloses a constant-voltage power supply mechanism of a lottery ticket vending machine, comprising: a support frame plate, snap plates, and a constant-voltage power supply device. A mounting frame and a bearing frame are fixed on the left end face of the support frame plate; a cover is fitted at the right side of the support frame plate; a desiccant block is fixed on the right inner wall of the cover by means of bolts; the constant-voltage power supply device is fixed on the right side of the support frame plate; connecting lines are fixed at the upper and lower sides of the constant-voltage power supply device; the connecting lines pass through openings; and the openings are formed on the upper and lower sides of the cover. The constant-voltage power supply mechanism of the lottery ticket vending machine can be mounted at a required position by means of the mounting frame and external bolts. The cover produces an isolation protection function for the constant-voltage power supply device. The desiccant block produces drying and dehumidification function to prevent affecting the normal operation of the constant-voltage power supply device due to dampness inside the cover. During the operation of the constant-voltage power supply device, fans blows air to the right to facilitate the cooling and heat dissipation of the constant-voltage power supply device.
