Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of herbal tea vending equipment, in particular to a herbal tea vending machine. BACKGROUND

[0002] With the improvement of consumers' health awareness and the progress of technology, traditional single-function vending machines have been unable to meet market demand. Although existing intelligent vending machines have achieved product recommendation and service automation to some extent, they still lack personalized health management. In particular, in traditional Chinese medicine, different people with different constitutions are suitable for different herbal tea formulas, which requires vending machines to have a higher degree of intelligence to achieve accurate recommendation.

[0003] Since herbal tea is a traditional Chinese medicine drink, its taste and quality are sensitive to temperature. Appropriate temperature can maximize the retention of effective components and unique flavors of traditional Chinese medicine. At the same time, the quality of herbal tea is also easily affected by bacteria. Since metal has good heat conduction performance, existing vending machines usually use metal heat conduction materials to control the temperature of the drink. Moreover, existing vending machines use pumps to transport the drink. However, metal can react with herbal tea to produce unknown chemical substances, which may cause poisoning of the drinker.

The outlet end is connected to the inlet section of the Chinese medicine filling switch 2131 through a flexible medical grade silicone hose. In order to further improve the safety, the hose adopts one-way valve protection measures throughout the process to prevent cross contamination caused by residual liquid backflow.

[0048] The working principle of the embodiment is that when the double-layer insulation container 21 needs to be filled with herbal tea, the herbal tea filling switch 2131 is opened, the medicine filling barrel 4 is placed on the top of the cabinet shell 1 and connected with the filling switch, the herbal tea flows through the pipe under the action of gravity, passes through the herbal tea filling switch 2131 and is filled into the inner container 211 of the double-layer insulation container 21, the heating tank 32 and the refrigeration tank 33 control the temperature of the insulation liquid 215 through the circulation pipeline 31, and the insulation liquid 215 transmits its temperature to the herbal tea in the inner container 211, so as to control the temperature of the herbal tea and avoid chemical reaction caused by contact between the herbal tea and the metal material. When the user opens the herbal tea outlet switch 121, the herbal tea filling switch 2131 is closed, the gas tank 131 sends sterile gas into the inner container 211, and the tea in the inner container 211 flows into the herbal tea outlet switch 121 through the outlet pipeline 214 under the action of gravity.

[0049] Embodiment 2,

[0050] Please refer to Figure 4 , Figure 4 The internal structure diagram of the cross-sectional view of the herbal tea vending machine provided in the second embodiment of the application, the structure of the embodiment is basically the same as that of the above-mentioned embodiment, and the difference lies in that the double-layer insulation container 21 only includes one, since the herbal tea is suitable for cold storage, only the refrigeration tank 33 works at this time, which is used for cold storage of the herbal tea, so as to achieve better storage effect. At this time, in order to avoid the problem of local freezing caused by excessive accumulation of refrigerant, a set of electronic expansion valve flow regulating device is specially added to intervene in the management link, which monitors and feeds back the current liquid working medium pressure parameter index data information in real time. At the same time, the outlet pipeline used in combination is changed to a double-channel separated layout form, which is respectively a heating pipe 2141 and a cold water pipe 2142, and the two branch lines are switched between synchronous operation modes. The heating pipe 2141 is a quick-heating pipe, which can be made of quartz glass material, has excellent electric heating efficiency characteristics, and is coated with an oxidation-resistant protective film to prolong the service life. The cold water pipe 2142 follows the standard specification requirements of ordinary silica gel pipe material to perform the production and processing process steps.

[0051] The implementation principle of the embodiment is that the structure of the temperature control assembly 3 is simplified, the complexity and cost of the equipment are reduced, and the storage effect of the herbal tea is improved.

[0052] The above are preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
