[0027] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] Example Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the material cart 100 provided in this embodiment. Figure 2 The diagram shown is a schematic of the internal structure of the small material cart 100.

[0029] The condiment cart 100 provided in this embodiment is applied in a milk tea shop. Specifically, it includes a cart body 110 and a condiment box 120. The condiment box 120 is detachably connected to the cart body 110 and is used to hold condiments needed for making milk tea, such as raisins, crushed peanuts, and hawthorn slices. The cart body 110 can transport the condiment box 120 to different areas of the milk tea shop to facilitate the shop staff in making milk tea.

[0030] In this embodiment, the vehicle body 110 is provided with a liquid-cooled cleaning chamber 111, which is used to selectively contain coolant or cleaning fluid. When the small material box 120 is connected to the vehicle body 110, its end away from the opening extends into the liquid-cooled cleaning chamber 111 to exchange heat with the coolant inside. The small material box 120 is also used to detach from the vehicle body 110 and be placed inside the liquid-cooled cleaning chamber 111 so that the cleaning fluid inside the liquid-cooled cleaning chamber 111 can clean the small material box 120.

[0031] During the milk tea making process, the small ingredient box 120 is connected to the vehicle body 110 and extends into the liquid-cooled cleaning chamber 111. The liquid-cooled cleaning chamber 111 contains coolant, which exchanges heat with the small ingredient box 120 in real time, absorbing the heat of the small ingredient box 120, thereby achieving low-temperature preservation of the ingredients and extending their shelf life.

[0032] When the small material box 120 needs to be cleaned, simply drain the coolant from the liquid-cooled cleaning chamber 111, inject cleaning fluid, place the small material box 120 inside the liquid-cooled cleaning chamber 111, and clean it using the cleaning fluid. Therefore, the small material cart 100 can achieve in-situ cleaning of the small material box 120, avoiding the need to move the small material box 120, reducing operational difficulty, improving operational efficiency, and preventing secondary contamination of the small material box 120.

[0033] In this embodiment, the small material cart 100 also includes a material box bracket 130, which is detachably connected to the cart body 110, and the small material box 120 is detachably connected to the material box bracket 130. That is, the small material box 120 is detachably connected to the small material cart 100 through the material box bracket 130.

[0034] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The diagram shown is a structural schematic of the material box support 130. Figure 4 The diagram shown is a structural schematic of the small material box 120.

[0035] In this embodiment, the opening of the liquid-cooled cleaning chamber 111 is located on the top wall of the vehicle body 110. The material box bracket 130 is detachably connected to the vehicle body 110 and covers the opening. The material box bracket 130 is provided with a hollow part 131 that communicates with the liquid-cooled cleaning chamber 111. The small material box 120 passes through the hollow part 131 with its opening facing upward and is hung on the edge of the hollow part 131.

[0036] In this embodiment, the material box bracket 130 is placed on the top wall of the vehicle body and covers the compartment opening. When the small material boxes 120 need to be cleaned, the material box bracket 130 can be moved to expose the opening of the liquid-cooled cleaning compartment 111, and then the multiple small material boxes 120 on the material box bracket 130 can be placed into the liquid-cooled cleaning compartment 111. In other embodiments, in order to ensure the stability of the overall structure, the material box bracket 130 can also be connected to the vehicle body 110 using fasteners, bolts, or other connecting parts.

[0037] In this embodiment, the material box support 130 is provided with multiple hollowed-out portions 131, which are arranged in an array. Multiple small material boxes 120 are attached to each of the multiple hollowed-out portions 131. Specifically, the openings of the small material boxes 120 are folded outwards on opposite sides to form two folded edges 121. During assembly, the small material boxes 120 pass through the hollowed-out portions 131 from bottom to top until the two folded edges 121 of the top opening contact and are supported by the opposite sides of the hollowed-out portions 131.

[0038] Understandably, the multiple small ingredient boxes 120 are used to hold different ingredients. In order to facilitate employees to quickly find the ingredients needed to make the current milk tea, in this embodiment, multiple indicator lights 132 are provided on the ingredient box support 130 corresponding to multiple hollow parts 131. The multiple indicator lights 132 are connected to the order system of the milk tea shop or the control system of the automatic milk tea production line. According to the order information, the indicator light 132 at the corresponding position of the small ingredient box 120 can be lit to prompt the store staff to obtain the ingredients that match the order information from the corresponding small ingredient box 120.

[0039] For example, if the current order contains raisins, the indicator light 132 corresponding to the small container 120 containing the raisins will be lit.

[0040] In this embodiment, multiple hollow sections 131 are arranged in an array on the material box support 130, and multiple indicator lights 132 are respectively set on the same side of each corresponding hollow section 131.

[0041] Furthermore, in this embodiment, a display 210 is also provided on the vehicle body 110. The display 210 is also connected to the order system of the milk tea shop or the control system of the automatic milk tea production line. It can display the required toppings according to the order information, as well as the required amount of different toppings and the order in which different toppings are added.

[0042] With the small material box 120 hanging on the hollowed-out portion 131 of the material box bracket 130, the opening of the small material box 120 faces upward, and the bottom of the small material box 120 extends into the liquid-cooled cleaning chamber 111 and is immersed below the surface of the coolant. Preferably, in this embodiment, both the coolant and the cleaning fluid are water, which is input to and output to the liquid-cooled cleaning chamber 111 through different paths.

[0043] Specifically, the liquid-cooled cleaning chamber 111 has a coolant inlet 112 and a coolant outlet 113 respectively provided on its two opposite side walls. The small material cart 100 also includes a water chiller 140, which is installed inside the cart body 110. The output end of the water chiller 140 is in fluid communication with the coolant inlet 112, and the input end of the water chiller 140 is in fluid communication with the coolant outlet 113.

[0044] In practical applications, the water chiller 140 outputs low-temperature water through its own refrigeration system. The low-temperature water flows into the liquid-cooled cleaning chamber 111 through the coolant inlet 112 for storage, in order to dissipate heat and cool the small material box 120 that extends into the liquid-cooled cleaning chamber 111. With heat exchange between the water chiller and the small material box 120, the temperature of the low-temperature water in the liquid-cooled cleaning chamber 111 gradually rises. When its temperature exceeds the preset value, it flows back to the water chiller 140 through the coolant outlet 113. The water chiller 140 then replenishes the liquid-cooled cleaning chamber 111 with low-temperature water that meets the temperature requirements through the coolant inlet 112.

[0045] Preferably, in this embodiment, the temperature of the low-temperature water in the liquid-cooled cleaning chamber 111 needs to be controlled between 0°C and 8°C. In order to achieve precise control of the liquid level and temperature of the coolant in the liquid-cooled cleaning chamber 111, a liquid level sensor 180 and a temperature sensor are also provided on the side wall of the liquid-cooled cleaning chamber 111 in this embodiment.

[0046] In another embodiment, in order to further improve the preservation effect, the liquid-cooled cleaning chamber 111 can form a circulation path with the water chiller 140 through the coolant outlet 113 and the coolant inlet 112 to provide a continuous flow of low-temperature water. The low-temperature water in the liquid-cooled cleaning chamber 111 continuously carries away the heat of the small material box 120 during the flow process, thereby obtaining a better heat exchange effect.

[0047] Please refer to the following: Figure 5 and Figure 6 , Figure 5 The diagram shows the internal structure of the liquid-cooled cleaning chamber 111. Figure 6 The diagram shows the structure of the small material box 120 placed inside the liquid-cooled cleaning chamber 111.

[0048] In this embodiment, the bottom of the liquid-cooled cleaning chamber 111 is provided with a guide wall 114 and a drain trough 115. The guide wall 114 is inclined relative to the horizontal plane, and the lower end of the guide wall 114 is connected to one side wall of the drain trough 115.

[0049] In practice, the coolant inlet 112 is located on the side wall of the liquid-cooled cleaning chamber 111, corresponding to the higher end of the guide wall 114, while the coolant outlet 113 is located on the side wall of the liquid-cooled cleaning chamber 111, corresponding to the lower end of the guide wall 114. Furthermore, a cleaning fluid inlet 116 is located on the side wall of the liquid-cooled cleaning chamber 111, corresponding to the higher end of the guide wall 114, and a drain outlet 117 is located on the drain tank 115.

[0050] The cleaning fluid inlet 116 is used to input external cleaning fluid into the liquid-cooled cleaning chamber 111. In this embodiment, there are two cleaning fluid inlets 116, which are used to input low-temperature cleaning fluid and high-temperature cleaning fluid, respectively. In this embodiment, they are used to input cold water and hot water.

[0051] It should be noted that the drain trough 115 is located at the lowest position in the liquid-cooled cleaning chamber 111. The drain outlet 117 of the drain trough 115 is used to drain the sewage mixed with cleaning fluid and dirt in the liquid-cooled cleaning chamber 111 after cleaning is completed, and also to drain the coolant in the liquid-cooled cleaning chamber 111 before cleaning begins.

[0052] Multiple longitudinal guide ribs 118 are arranged side-by-side and spaced apart on the bottom wall 114 of the guide flow. A guide groove 1181 is formed between any two adjacent longitudinal guide ribs 118, extending from the higher end to the lower end of the bottom wall 114. The multiple longitudinal guide ribs 118 are used to place the small material box 120. Limiting transverse ribs 1182 are provided across the surface of the multiple longitudinal guide ribs 118. The multiple limiting transverse ribs 1182 are arranged at intervals in the extending direction of the longitudinal guide ribs 118, and the limiting transverse ribs 1182 are used to stop and limit the small material box 120.

[0053] Understandably, before cleaning the small material boxes 120, multiple small material boxes 120 are placed on multiple guide ribs 118 with their openings tilted downwards, and positioned between two adjacent limiting ribs 1182. The front and rear stops of the two limiting ribs 1182 limit the small material boxes 120, ensuring their stability during cleaning. Following the tilted guide ribs 118, the downward tilt of the openings of the small material boxes 120 ensures that internal contaminants can flow out smoothly during cleaning, preventing residue.

[0054] Furthermore, since a guide channel 1181 is formed between two adjacent guide longitudinal ribs 118, after the material box is placed, the guide channel 1181 is located below the material box, which can effectively receive the cleaning liquid flowing down from the outer wall and bottom of the small material box 120, and quickly guide it into the drain trough 115 along the inclined direction to prevent dirt residue. At the same time, the guide channel 1181 and the inclined guide bottom wall 114 work together to significantly improve the flow efficiency of the cleaning liquid, avoid liquid stagnation or accumulation, ensure the continuous flushing effect of the cleaning liquid on the small material box 120, and facilitate the thorough drainage of sewage, reducing residue, thereby significantly improving the cleaning effect.

[0055] In order to achieve the desired cleaning effect, in this embodiment, an ultrasonic transducer 150 is also provided on the side wall of the liquid-cooled cleaning chamber 111. The ultrasonic transducer 150 is configured to operate when cleaning the small material box 120 to achieve efficient cleaning of the small material box 120.

[0056] To achieve rapid drying of the small material box 120 after cleaning and prevent bacterial growth, in this embodiment, a heating element 160 is also provided on the side wall of the liquid-cooled cleaning chamber 111. The heating element 160 is configured to generate heat after the small material box 120 is cleaned to dry it. It should be noted that the heating principle of the heating element 160 can be resistance heating, that is, the heating element 160 can be provided with a heating resistor connected to the circuit.

[0057] Furthermore, in this embodiment, the material cart 100 is also equipped with a dosing device 170, which is configured to add cleaning and disinfecting agents into the liquid-cooled cleaning chamber 111 to further improve the cleaning effect.

[0058] Please refer to the following: Figure 7 , Figure 7 The image shown is a cross-sectional view of the dosing device 170.

[0059] The dosing device 170 provided in this embodiment includes a linear motor 171 and a dosing tank 172. The linear motor 171 and the dosing tank 172 are disposed on the top wall of the vehicle body. The dosing tank 172 has a stacking channel 1721 and a dropping channel 1722 that are adjacent to each other and connected. The stacking channel 1721 is used to stack solid cleaning and disinfecting agents, and the dropping channel 1722 extends downward and communicates with the liquid-cooled cleaning chamber 111. The output end of the linear motor 171 extends into the stacking channel 1721 from the side of the stacking channel 1721 away from the dropping channel 1722, and is used to push the cleaning and disinfecting agent at the bottom of the stacking channel 1721 into the dropping channel 1722, so that the cleaning and disinfecting agent can fall into the liquid-cooled cleaning chamber 111 along the dropping channel 1722.

[0060] In addition, in this embodiment, a UV disinfection lamp 220 is also provided on the top wall of the vehicle body. The UV disinfection lamp 220 is located above the opening of the liquid-cooled cleaning chamber 111 and can irradiate and disinfect the internal environment of the liquid-cooled cleaning chamber 111. It can also irradiate and disinfect the multiple small material boxes 120 hanging on the material box bracket 130 and the small materials contained in each small material box 120 when the material box bracket 130 covers the opening of the liquid-cooled cleaning chamber 111.

[0061] In fact, the material cart 100 provided in this embodiment also includes a controller 190, which is installed on the vehicle body. The controller 190 is communicatively connected to the liquid level sensor 180, the temperature sensor, and the water chiller 140. Based on the detection results of the liquid level sensor 180 and the temperature sensor, the controller controls the operation of the water chiller 140 to control the content and temperature of the cleaning fluid in the liquid-cooled cleaning chamber 111.

[0062] In another embodiment, the controller 190 can also be communicatively connected to the display 210, the ultrasonic transducer 150, the heating element 160, and the linear motor 171 of the dosing device 170, respectively, to realize automated control of the cleaning process.

[0063] Specifically, the cleaning fluid inlet 116 is connected to an external cleaning fluid supply path, and the drain outlet 117 is connected to an external drain path. Both the cleaning fluid inlet 116 and the drain outlet 117 are equipped with electrically controlled valves that communicate with the controller 190. The display 210 is equipped with an emptying button for employees to input emptying commands and a cleaning button for inputting cleaning commands. Upon receiving an emptying command, the controller 190 controls the electrically controlled valve at the drain outlet 117 to open, thereby emptying the coolant from the liquid-cooled cleaning chamber 111.

[0064] Next, the employee places the small material box 120 into the liquid-cooled cleaning chamber 111 and presses the cleaning button to input the cleaning command. Upon receiving the cleaning command, the controller 190 controls the linear motor 171 of the dosing device 170 to add cleaning and disinfecting agents into the liquid-cooled cleaning chamber 111. Then, the controller 190 opens the electrically controlled valve at the cleaning fluid inlet 116 to introduce cleaning fluid into the liquid-cooled cleaning chamber 111. Afterward, the controller 190 controls the ultrasonic transducer 150 to clean the small material box 120 immersed in the cleaning fluid.

[0065] After the preset cleaning time is reached, the controller 190 controls the electrically controlled valve at the drain port 117 to open, thereby emptying the wastewater in the liquid-cooled cleaning chamber 111. Then, the controller 190 controls the electrically controlled valve at the cleaning fluid inlet 116 to reopen, introducing cleaning fluid to rinse the material box. After rinsing, the controller controls the electrically controlled valve at the drain port 117 to reopen, emptying the wastewater again. After emptying, the controller 190 controls the heating element 160 to start, drying the small material box 120. After the preset time is reached or the humidity sensor detects that the small material box 120 is dry, the controller 190 controls the heating element 160 to stop operating.

[0066] After cleaning, employees can remove the small material box 120 and re-hang it on the material box bracket 130. The material box bracket 130 is then placed on the top wall of the vehicle body 110 to cover the opening of the liquid-cooled cleaning chamber 111. After completion, the UV disinfection lamp 220 is turned on to disinfect and sterilize the small material box 120.

[0067] In summary, the small ingredient cart 100 provided in this embodiment can keep small ingredients fresh at low temperatures and can also clean the small ingredient box 120 in situ, reducing the difficulty of operation, improving the efficiency of operation and preventing secondary pollution.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
