Detailed Description

For the purpose of illustrating the technical contents, structural features, and objects and functions of the invention in detail, reference will be made to the following detailed description taken in conjunction with the accompanying drawings. The up, down, left, right, front, and rear positional relationships described in the present embodiment correspond to the positional relationships of the vending machine shown in fig. 1, respectively.

As shown in fig. 1, the vending machine includes a rectangular parallelepiped body 11, an opening is provided at the front of the body 11, a front door 113 is installed at the opening, a goods taking opening 111 and a control panel 18 for user operation are provided on the front door 113, the goods taking opening 111 and the control panel 18 are both located at the right side of the front door 113, the goods taking opening 111 is located at the lower side of the control panel 18, and an advertisement window or a transparent viewing window is installed at the left side of the front door 113.

As shown in fig. 2, the inside of the machine body 11 has a commodity storage chamber, the commodity storage chamber is divided into multiple storage spaces from top to bottom, a drawer 12 is disposed in each storage space, and a pulling mechanism 13 is disposed between each drawer 12 and two inner side wall plates of the machine body 11. Specifically, as shown in fig. 5, the left side wall plate and the right side wall plate of the machine body 11 are provided with first sliding bars 131 extending in the front-back direction, and a second sliding bar 132 slidably engaged with the first sliding bars 131 is installed at a corresponding position of each layer of drawers 12, so that each layer of drawers 12 can be freely drawn out of the machine body 11 from the machine body 11 or pushed out of the machine body 11 into the machine body 11, thereby facilitating the addition of commodities by a user. Of course, the specific implementation manner of the drawing mechanism 13 is various, and is not limited to the structure in which two sliding bars are matched, and may also be a structure in which a sliding rail sliding block, a sliding block sliding groove, and the like are in sliding fit through two corresponding sliding pieces.

As shown in fig. 3, the rear portion of the body 11 is also provided with an opening, and for the sake of convenience, in this embodiment, the opening at the front portion of the body 11 is referred to as a first opening 112, and the opening at the rear portion of the body 11 is referred to as a second opening 114. Referring to fig. 2, when the front door 113 is opened and the rear door 115 is closed, similar to the vending machine of the prior art, the drawer 12 is drawn out of the machine body 11 from the rear to the front from the first opening 112, and the user can add the goods to the machine body 11 from the front. When the front door 113 of the machine body 11 is opened and the rear door 115 is closed, the front part of the machine body 11 functions as a vending window, and the rear part of the machine body 11 can be used as a commodity supply window, so that a vending mode of a front shop and a rear shop can be realized.

As shown in fig. 4 and 5, each tier of drawers 12 includes a drawer body 121 and a delivery mechanism 122 mounted on the drawer body 121, the drawer body 121 has a cargo passage 1211 extending in the left-right direction, and the delivery mechanism 122 is used for pushing the goods out of the cargo passage 1211 from left to right. The delivery mechanism 122 includes a delivery motor 1221 mounted on the drawer body 121 and located on the left side of the cargo passage 1211, and a delivery spring 1222 drivingly connected to the delivery motor 1221 and located in the cargo passage 1211, wherein the goods are stacked on the delivery spring 1222, and the delivery motor 1221 drives the delivery spring 1222 to rotate to deliver the goods from the cargo passage 1211. Specifically, there are two discharging springs 1222, and the two discharging springs 1222 are respectively located at two sides of the width direction of the cargo passage 1211, that is, are arranged opposite to each other in the front-rear direction. Both of the two shipment springs 1222 extend in a length direction of the shipment passage 1211, i.e., in a left-right direction. A gear box 1223 is arranged between the goods discharging motor 1221 and the two goods discharging springs 1222 in a transmission manner, the gear box 1223 is provided with an input shaft and two output shafts which rotate synchronously, the input shaft of the gear box 1223 is fixedly connected with the shaft of the goods discharging motor 1221, and the two output shafts of the gear box 1223 are respectively fixedly connected with the two goods discharging springs 1222.
