Description

Technical Field

[0001] The utility model relates to the technical field of unmanned vending, and in particular to an unmanned vending monitoring device. Background Art

[0002] Unmanned vending machines are commonly used equipment in commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as a 24-hour mini supermarket. At present, the common unmanned vending machines in China are usually divided into four types: beverage unmanned vending machines, food unmanned vending machines, comprehensive unmanned vending machines, and adult products unmanned vending machines. In order to ensure the safety of the operation of unmanned vending machines, monitoring devices are often installed on the unmanned vending machines.

[0003] For example, the Chinese utility model patent with application number: 202021279192.1 discloses an unmanned vending monitoring device, including an unmanned vending machine body, a camera and transparent tempered glass. A top plate is installed on the top of the unmanned vending machine body, and a left-right symmetrical camera, a mounting plate and transparent tempered glass are installed below one side of the top plate. The utility model improves the overall protection performance of the unmanned vending monitoring device by arranging transparent tempered glass on the outside of the camera, and is provided with a fan and a dustproof net, which has a certain dustproof and heat dissipation effect, prolongs the service life of the unmanned vending monitoring device, and is installed with a cleaning mechanism to facilitate the cleaning of the transparent tempered glass surface, ensuring the clarity of the monitoring screen.

[0004] The above patent can ventilate and dissipate heat for the camera through the setting of the fan, and can filter and intercept dust impurities in the air through the setting of the dustproof net to protect the camera. However, the dustproof net in the above patent is arranged between the camera and the fan, so the dustproof net cannot protect the fan from dust. When used for a long time, the fan blades are prone to absorb a large amount of dust impurities, which increases the load of the fan, affects the efficient operation of the fan, and reduces the heat dissipation effect of the camera. Moreover, the dustproof net in the above patent is located between the camera and the fan, which is not convenient for the user to remove it for cleaning and maintenance. When the dustproof net is used for a long time, its surface is prone to absorb a large amount of dust. If it is not cleaned and maintained in time, it will cause poor air circulation, which is not conducive to the ventilation and heat dissipation of the camera. Utility Model Content

[0009] In actual application, when the dust screen needs to be removed for cleaning and maintenance, the user holds the pull rod and rotates it to overcome the damping force of the damping shaft to drive the limit plate to rotate, and rotates the limit plate to the side away from the installation frame to release the limit fixation of the installation frame. The user can then easily remove the installation frame from the vent, thereby indirectly realizing the disassembly of the dust screen and the fan, making it convenient for the user to clean and maintain the dust screen and the fan, thereby ensuring the cleanliness of the dust screen and the fan, which is beneficial to the efficient operation of the fan and can improve the air intake unobstructedness of the dust screen.

[0010] As a further description of the above technical solution: the side of the limiting piece close to the unmanned vending machine body is arranged to abut against the edge of the installation frame.

[0026] The limit assembly 8 includes a damping shaft 801 which is mounted on the vending machine body 1 for damping rotation. The end of the damping shaft 801 away from the vending machine body 1 is fixedly connected to a limit plate 802. The side of the limit plate 802 away from the vending machine body 1 is fixedly connected to a pull rod 803. The side of the limit plate 802 close to the vending machine body 1 is arranged to abut against the edge of the mounting frame 5.

[0027] Working principle: During the use of the unmanned vending machine body 1, the surrounding environment is monitored through the camera 4, and the temperature in the protection frame 3 can be monitored through the setting of the temperature sensor 10, and the monitored data is transmitted to the PLC controller 9. When the temperature in the protection frame 3 is higher than the preset value, the fan 7 is turned on by the PLC controller 9 to accelerate the circulation speed of the gas in the protection frame 3 and the external gas, so as to realize ventilation and heat dissipation of the camera 4 installed in the protection frame 3, so as to avoid the working environment temperature of the camera 4 being too high and affecting the performance;

[0028] Furthermore, by setting the dustproof net 6, dust impurities in the gas entering the protection frame 3 can be filtered and intercepted, so as to prevent dust impurities from being adsorbed on the fan 7 or the camera 4, thereby providing dustproof protection for the fan 7 and the camera 4;

[0029] After the dust screen 6 has been used for a period of time, its surface tends to absorb a lot of dust and impurities. When the dust screen 6 needs to be removed for cleaning and maintenance, the user holds the pull rod 803 and rotates it to overcome the damping force of the damping shaft 801 and drive the limit plate 802 to rotate. The limit plate 802 is rotated to the side away from the installation frame 5, and the limit fixation of the installation frame 5 can be released. Then the user can easily remove the installation frame 5 from the vent 2, thereby indirectly realizing the disassembly of the dust screen 6 and the fan 7, making it convenient for the user to clean and maintain the dust screen 6 and the fan 7 to ensure the cleanliness of the dust screen 6 and the fan 7.
