Pressure-differential edible liquid vending system with fresh-keeping function

Abstract

The invention relates to the field of vending machines. The pressure-differential edible liquid vending system with a fresh-keeping function comprises a liquid storage system, an electrical control system and a charging system. The liquid storage system comprises tank bodies for storing edible liquid, on which liquid collecting pipes for draining the edible liquid and a replenishing port for replenishing the edible liquid to the tank bodies are arranged, the liquid collecting pipes are provided with electromagnetic stop valves for switching the liquid collecting pipes in open or closed status,electronic flow meters for measuring outflow volume of the edible liquid, and liquid collecting buttons for manually controlling working status of the electromagnetic stop valves The electrical control system is connected with the electromagnetic stop valves and the electronic flow meters by signals and can select the tank bodies. The charging system is connected with the electrical control system signals. A printing system is used to print an invoice corresponding to an amount paid out after payment. The system of the invention has functions of keeping freshness of beverages, ensuring quality under control in the whole process from a manufacturer to a consumer and cultivating good habit of self-conscious tax payment by consumers and businesses in buying and selling process.

Description

technical field [0001] The invention relates to the field of automatic vending devices, in particular to the field of automatic vending of liquid beverages. Background technique [0002] At present, there are two main forms of edible liquid sales in the domestic market: bulk and bottled. According to the analysis of the national per capita income and expenditure, taking liquor as an example, the share of bulk liquor accounts for more than 60% of the total edible liquid sales, and bottled liquor is a waste of packaging. Consumables and bulk retail liquor are faced with counterfeiting and non-payment of consumption tax by merchants. [0003] In the prior art, bulk beverages are seldom sold automatically because it is difficult to control the quality of the beverages. For example, the existing water dispenser uses municipal tap water, does not need to store water, and can be supplied and filtered at any time, so there is no freshness preservation feature.

[0002] At present, there are two main forms of edible liquid sales in the domestic market: bulk and bottled. According to the analysis of the national per capita income and expenditure, taking liquor as an example, the share of bulk liquor accounts for more than 60% of the total edible liquid sales, and bottled liquor is a waste of packaging. Consumables and bulk retail liquor are facing counterfeiting and non-payment of consumption tax by merchants

[0003] In the prior art, bulk beverages are seldom sold automatically because it is difficult to control the quality of the beverages. For example, the drinking fountains in the prior art use municipal tap water, do not need to store water, and can supply water at any time and filter it at any time, so there is no freshness preservation feature

[0004] Also some technical schemes adopt the mode of bottled water storage to store drinking water, for example Chinese patent (publication number: CN201556251U) proposes a kind of automatic vending water dispenser, this water dispenser stores drinking water, and it mainly adopts bottled water, Water sales can be completed only by controlling the switch during automatic sales. This method has many problems such as the inability to guarantee the quality of water.
