Description

Technical Field

[0001] This utility model relates to the technical field of ice cream and milk tea carts, specifically a mobile DC inverter ice cream and milk tea cart. Background Technology

[0002] The cold beverage market is currently booming, with various brands of milk tea and ice cream shops enjoying immense popularity, especially among young people. However, franchising a branded cold beverage shop can easily cost tens of thousands of yuan, and with rent and renovations, the cost can reach hundreds of thousands more. This high barrier to entry discourages those with insufficient capital from entering the industry. Business is good if the surrounding area is bustling, but if the location and environment are unfavorable, profits can be low, leading to losses. This has led to the emergence of mobile milk tea carts, which offer convenience, speed, and flexible operation. Unaffected by geographical conditions, they can be moved to different locations with higher foot traffic. Furthermore, some tourist attractions lack power, preventing the establishment of mobile milk tea carts. Therefore, some businesses have placed commonly used cold beverage and milk tea equipment in mobile street vendor carts or customized food trucks.

[0003] However, existing milk tea and cold drink equipment often consumes a relatively large amount of power due to refrigeration and heating functions. The external power supply is generally insufficient in terms of wiring or switch capacity, making it difficult to meet the power demand and easily causing the wiring or switch to burn out. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a mobile DC inverter ice cream and milk tea cart.

[0005] To solve the above problems, the technical solution of this utility model is: a mobile DC inverter ice cream and milk tea cart, comprising: The vehicle body has wheels installed underneath it, and an ice maker, an ice cream machine, and milk tea processing equipment are installed on the vehicle body. A clean water tank, which is installed inside the lower part of the vehicle body; Wastewater tank, wherein the wastewater tank is installed inside the vehicle body below the clean water tank, located in front of the clean water tank; A power system, the power system including a storage-type silent generator set, the storage-type silent generator set having at least two sets of batteries; A power control converter is electrically connected to a storage-type silent generator set. When the voltage of the currently supplied battery pack is lower than a first set value, the power control converter automatically switches to another battery pack for power supply and controls the storage-type silent generator set to start, charging the battery pack with the low voltage. A low-voltage DC inverter refrigeration system, which is connected to an ice maker and an ice cream maker.

[0006] Furthermore, the low-voltage DC inverter refrigeration system includes a refrigeration compressor and refrigeration pipes, and the refrigeration pipes are connected to an ice maker and an ice cream machine.

[0007] Furthermore, the refrigeration compressor includes a DC inverter compressor connected to refrigeration pipes, a radiator, a fan for forced cooling of the radiator, and a housing for overall protection.

[0008] Furthermore, the power system consists of three sets of twelve-volt lead-acid batteries connected in series to provide a 2-4 volt DC operating voltage for the entire vehicle equipment.

[0009] Furthermore, the power system is a lithium battery pack.

[0010] Furthermore, a sales window is also provided on one side of the vehicle.

[0011] Furthermore, the vehicle body is modified from a new energy chassis.

[0012] The advantages of this invention compared to existing technologies are as follows: This utility model ice cream and milk tea cart borrows the general shape and driving mechanism of common electric food carts on the market. It uses six 12-volt batteries as the main power source to support the cart's movement and provide power for cold drink preparation. It is also equipped with a 24V silent self-starting and stopping generator to supplement the cart's power supply, ensuring that it still has enough power for normal operation after work. It also employs DC low-voltage frequency conversion technology for energy efficiency. When the refrigeration equipment is operating, the main power is divided into three groups, each consisting of two 24V batteries. All refrigeration and milk tea equipment on the cart operate on this voltage. When the equipment is running, if the voltage of the first group of batteries falls below a set value, the power automatically switches to the second group of batteries to continue operation. At this time, the hidden silent generator automatically starts to charge the first group of batteries. When the voltage of the second group of batteries falls below the set value, the power switches to the third group of batteries. After the first group of batteries is fully charged, the silent generator switches back to the second group of batteries to continue charging. This process can be repeated cyclically. This invention is not limited to lead-acid batteries; lithium batteries can be used to increase costs. Attached Figure Description

[0018] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figures 1 to 2 As shown, the technical solution of this utility model is as follows: a mobile DC inverter ice cream and milk tea cart, comprising: a vehicle body 1 with wheels installed below it, the vehicle body 1 serving as the main carrier for easy movement via the wheels; an ice maker 2, an ice cream machine 3, and milk tea processing equipment 8 installed on the vehicle body 1; a clean water tank 5 installed inside the lower part of the vehicle body 1; and a wastewater tank 4 installed inside the lower part of the vehicle body 1, located in front of the clean water tank 5. The wastewater tank 4 and the clean water tank 5 are used to recycle wastewater and store clean water, respectively. The power system includes a storage-type silent generator set 6, which contains at least two sets of batteries. A power control converter 7 is electrically connected to the storage-type silent generator set 6. The power control converter 7 is activated when the voltage of the currently supplied battery set is lower than a first preset value. When on duty, it automatically switches to another set of battery power supply and controls the start of the energy storage silent generator set 6 to charge the battery pack with low voltage, so as to achieve a continuous supply of power and ensure that the vehicle still has the power required for movement after the business ends. The low-voltage DC inverter refrigeration system is connected to the ice maker 2 and the ice cream machine 3. The ice maker 2 and the ice cream machine 3 provide a cold source. The low-voltage DC inverter refrigeration system includes a refrigeration compressor 10 and a refrigeration pipe 11. The refrigeration pipe 11 is connected to the ice maker 2 and the ice cream machine 3. The refrigeration compressor 10 includes a DC inverter compressor 1004 connected to the refrigeration pipe 11, a radiator 1002, a fan 1003 for forced cooling of the radiator, and a housing 1001 for overall protection.

[0020] like Figures 1 to 2As shown, the power system consists of three sets of twelve-volt lead-acid batteries connected in series to provide a 24-volt DC working voltage for the entire vehicle equipment. The power system is a lithium battery pack. A sales window 9 is also opened on one side of the vehicle body 1 for displaying and selling products to customers. The vehicle body is modified from a new energy chassis.

[0021] In practical use, after the vehicle is driven to a suitable location and the equipment power is turned on, the power control converter 7 first uses the power from the first set of batteries. When the voltage is detected to be lower than the set value, the power supply line is automatically switched to the second set of batteries to ensure that the equipment does not stop. At the same time, the energy storage silent generator set 6 is immediately started, and the generated power is converted to charge the first set of batteries. When the second set of batteries is about to run out of power, the controller switches to the third set of batteries for power supply and switches the generator to charge the second set of batteries. This cycle ensures a continuous supply of energy. The clean water tank 5 provides water for all equipment, and the wastewater after use is collected in the wastewater tank 4 for centralized treatment. When the ice cream machine 3 and the ice maker 2 are working, the DC inverter compressor 1004, the radiator 1002 and the fan 1003 work together to cool and dissipate heat.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
