Description

Technical Field

[0001] This utility model relates to the technical field of fruit and vegetable beverage processing equipment, and in particular to a fruit and vegetable beverage concentration adjustment device. Background Technology

[0002] To meet the diverse taste preferences and nutritional needs of different groups, the market demands higher levels of personalization and diversification in fruit and vegetable beverages, such as variations in juice consistency and sweet-to-sour ratio. Currently, the concentration adjustment of fruit and vegetable beverages primarily relies on two methods: Fixed-concentration pre-packaged mode: The vast majority of bottled or boxed fruit and vegetable beverages on the market have fixed formulas and concentrations. The concentration cannot be changed after purchase. If consumers find the beverage too strong or too weak, they can only manually dilute or mix it by adding water or other beverages. Simple manual adjustment device: Some high-end water dispensers or beverage machines are equipped with a simple concentrate-water mixing function, allowing users to roughly control the mixing ratio using knobs or buttons. However, existing technologies have the following problems: Manual addition makes it difficult to precisely control the proportions, often relying on personal intuition, resulting in inconsistent taste and failing to achieve the ideal drinking state. Simple manual adjustment devices usually suffer from uneven mixing, inaccurate proportion control, and cross-contamination due to residual liquid. Their adjustment mechanisms are often crude and cannot achieve fine-grained, stepless adjustment of the concentration of fruit and vegetable beverages. In addition, the flow channel design of existing devices is usually simple, and concentrated fruit and vegetable juice is prone to sedimentation and adhesion to the walls of internal pipes or containers, which not only causes waste but also makes the initial concentration of each batch unstable, affecting the user experience.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figures 1 to 6 As shown, a fruit and vegetable beverage concentration adjustment device includes an L-shaped box 1. A receiving plate 2 is fixedly installed at the front vertical part of the L-shaped box 1. Several mixing mechanisms 16 are evenly arranged in the horizontal part of the inner cavity of the L-shaped box 1. A water volume control mechanism 17 is provided on the front side of each of the several mixing mechanisms 16. A fruit and vegetable concentrate storage bottle 15 is provided on the rear side of each of the several mixing mechanisms 16. The mixing mechanism 16 includes an electric push rod 161, with a mixing bottle 162 fixedly mounted on its top. The output end of the electric push rod 161 extends into the inner cavity of the mixing bottle 162 and is fixedly mounted with a pressure plug 163. A rubber ring 164 is fitted around the outer ring of the pressure plug 163, and the rubber ring 164 fits against the inner ring of the mixing bottle 162 to ensure a tight seal when the pressure plug 163 moves within the mixing bottle 162. A concentrate injection pump 165 is fixedly mounted on the top of the mixing bottle 162. The input end of the liquid injection pump 165 is connected to the bottom of the inner cavity of the fruit and vegetable concentrate storage bottle 15 corresponding to the rear side of the mixing bottle 162 through the filling pipe 166. The output end of the liquid injection pump 165 is connected to the inner cavity of the mixing bottle 162 and is located below the lower pressure plug 163. The bottom of the mixing bottle 162 is fixedly connected to the outlet pipe 167 that passes through its inner cavity. The bottom end of the outlet pipe 167 passes through to the lower horizontal position of the L-shaped box 1 and is fixedly installed with a beverage nozzle 168. The beverage nozzle 168 is located above the receiving plate 2. The L-shaped housing 1 integrates a PLC microcontroller. Users can input their concentration preferences (such as low, medium, high concentration or specific ratio values) through a touch screen or knob located at the front of the housing. Based on the user input, the microcontroller calculates the required volume of concentrate and water, and controls the running time of the concentrate injection pump 165 (to control the amount of concentrate) and the stroke of the electric push rod 172 (to control the amount of water), achieving stepless adjustment.

[0016] The water control mechanism 17 includes a metering water bottle 171. An electric push rod 172 is fixedly installed on the top of the metering water bottle 171. The output end of the electric push rod 172 passes through the inner cavity of the metering water bottle 171 and is fixedly installed with a pressure stopper 173. The side wall of the pressure stopper 173 fits against the inner ring of the metering water bottle 171 to ensure the sealing when the pressure stopper 173 moves inside the metering water bottle 171. An annular tube 174 is sleeved under the outer wall of the mixing bottle 162. The metering water bottle 171 communicates with the inner cavity of the annular tube 174. Several concentration adjustment spray heads 175 that communicate with the inner cavity of the mixing bottle 162 are fixedly connected to the inner ring array of the annular tube 174. A water supply connection pipe 14 that communicates with the inner cavity of the metering water bottle 171 is fixedly connected to the front side of the metering water bottle 171. The communication point between the water supply connection pipe 14 and the inner cavity of the metering water bottle 171 is located below the pressure stopper 173. The concentration adjustment spray head 175 sprays water tangentially toward the inner wall of the mixing bottle 162, forming a vortex to fully mix the concentrate with water. In addition, the electric push rod 161 can drive the lower stopper 163 to move up and down several times during the mixing process. The friction between the rubber ring 164 and the inner wall of the mixing bottle 162 generates shear force, which further enhances the mixing effect and avoids sedimentation. The second pressure plug 173 has a ring array with several through holes 1731 extending vertically. Each of the through holes 1731 has a duckbill check valve 1732 with the water inlet facing upward. The duckbill check valve 1732 allows water to flow from below the second pressure plug 173 to the top, but seals the through holes 1731 when the second pressure plug 173 descends to prevent water from flowing back. A water pump 11 is fixedly installed on the right side of the horizontal inner cavity of the L-shaped box 1. The input end of the water pump 11 is fixedly connected to the water inlet pipe 12. The other end of the water inlet pipe 12 passes through to the right side of the L-shaped box 1 and is connected to a clean water pipe. The output end of the water pump 11 is fixedly connected to the water outlet pipe 13. The other ends of several water supply connection pipes 14 connected to several metering water bottles 171 are respectively fixedly connected to the inner cavity of the water outlet pipe 13. The top of each fruit and vegetable concentrate storage bottle 15 is fixedly connected to an injection tube 151. The top ends of several injection tubes 151 extend to the top of the L-shaped box 1. The outer wall of the top of several injection tubes 151 is provided with an external thread wall. The top of the injection tube 151 is threaded with a threaded cap 152 through the external thread wall for sealing and replenishing the concentrate. The device has a cleaning mode. After the user starts it through the controller, the water pump 11 pumps clean water into the metering water bottle 171 through the water supply connection pipe 14, and then rinses the mixing bottle 162 through the ring pipe 174 and the concentration adjustment spray head 175. At the same time, the electric push rod 161 pushes the lower stopper 163 to the bottom of the mixing bottle 162, and discharges the residual liquid from the liquid outlet pipe 167. In addition, the fruit and vegetable concentrate storage bottle 15 can be disassembled and cleaned by unscrewing the threaded cap 152. The rubber ring 164 and the lower stopper 173 are made of food-grade silicone material, which is corrosion-resistant and easy to clean. The L-shaped housing 1 is equipped with a 24V DC power supply module, which is connected to a microcontroller, electric actuator 161, electric actuator 2172, concentrate injection pump 165 and water pump 11 via cables. The microcontroller controls the movement speed of the electric actuator and the start and stop of the water pump through PWM signals.

[0017] The working principle of this fruit and vegetable beverage concentration adjustment device will be explained in detail below.

[0018] like Figure 1-6 As shown, when a user needs to adjust the concentration of the fruit and vegetable beverage, a certain amount of concentrate is first drawn from the fruit and vegetable concentrate storage bottle 15 by the concentrate injection pump 165 and injected into the mixing bottle 162 through the filling pipe 166. The injection volume of the concentrate is precisely controlled by the control system of the concentrate injection pump 165 to adapt to different concentration requirements. Subsequently, the water volume control mechanism 17 starts to work. The water pump 11 draws purified water from the external purified water pipe through the water inlet pipe 12 and sends the water into the metering water bottle 171 through the water outlet pipe 13 and the water supply connection pipe 14. When the water enters the metering water bottle 171, the pressure stopper 173 is in the initial position. The water enters the space above the pressure stopper 173 through the duckbill one-way valve 1732. When water needs to be added, the electric push rod 172 pushes the pressure stopper 173 downward. The duckbill one-way valve 1732 closes under pressure, sealing the through hole 1731. The water is pressed down and flows through the annular pipe 174 from the concentration adjustment spray. Water is sprayed into the mixing bottle 162 by the nozzle 175. The amount of water added is precisely controlled by the stroke of the electric push rod 172, thus achieving stepless adjustment of the water volume. In the mixing bottle 162, the concentrate and water are fully mixed by the spray of the concentration adjustment nozzle 175, ensuring uniform mixing. After mixing, the electric push rod 161 pushes the lower stopper 163 downward. Using the sealing effect of the rubber ring 164, the mixed beverage is pushed out from the outlet pipe 167 and flows out through the beverage nozzle 168 into the container on the receiving plate 2. Users can achieve fine adjustment of concentration by controlling the ratio of concentrate to water. Throughout the process, the device ensures the accuracy and stability of concentration adjustment through the coordinated work of the electric push rod, pump and one-way valve, avoiding the inconvenience of manual adjustment and the problem of uneven mixing. At the same time, the design of the annular tube and the concentration adjustment nozzle promotes mixing, reduces residue and cross-contamination, and improves the user experience.
