Description

Technical Field

[0001] The present invention relates to the technical field of beverage machines, and more specifically to a peristaltic discharging anti-pulse backflow precise discharging structure. Background Art

[0002] Beverage machines use peristaltic pumps to precisely control the flow rate and delivery of beverages, thereby providing consumers with various flavored beverages. Such devices usually have multiple functions, such as selecting beverage types, adjusting beverage concentrations, adding toppings, etc., to meet the needs of different consumers. The peristaltic pump pumps fluid by alternately squeezing and releasing an elastic delivery hose with rollers. When the roller moves forward, it squeezes a part of the hose, causing the fluid in that part to move forward. As the roller continues to move, the fluid is continuously pumped out.

[0003] There is a dripping phenomenon at the water outlet of beverage machines that utilize peristaltic pumps. This is a relatively common and complex fluid phenomenon. When the peristaltic pump stops working, the liquid in the pipeline will naturally drop along the edge of the outlet due to its own gravity and ductility. When the peristaltic pump transports liquid, due to the squeezing and releasing of the hose by the rollers, a pulse phenomenon will occur, causing the beverage machine to discharge water intermittently and unable to discharge stably. And affected by the pulse, when the peristaltic pump stops working, some droplets in the hose will continue to drip, requiring staff to clean the tabletop. Summary of the Invention

[0004] (1) Technical problems to be solved: Aiming at the deficiencies of the prior art, the present invention provides a peristaltic discharging anti-pulse backflow precise discharging structure, which has the advantages of precise and uniform discharging and avoiding dripping, and solves the problem of the beverage machine being affected by the pulse of the peristaltic pump.

[0005] (2) Technical solutions: To achieve the above-mentioned purpose of precise and uniform discharging and avoiding dripping, the present invention provides the following technical solutions: A peristaltic discharging anti-pulse backflow precise discharging structure, including a beverage machine body. A refrigerated cabinet for placing beverages is provided at the bottom of the beverage machine body. A pump body groove is provided on the tabletop of the beverage machine body. A peristaltic pump is provided in the pump body groove. A hose connection is provided between the peristaltic pump and the cold beverage placed in the refrigerated cabinet. An outlet is provided on the side of the pump body groove. The peristaltic pump is connected to the outlet through a hose to transport the beverage from the refrigerated cabinet to the outlet. An elastic bladder is provided on the hose between the peristaltic pump and the outlet. After the beverage flows to the peristaltic pump, it first flows into the elastic bladder and then flows to the outlet. The elastic bladder has elasticity and can produce a certain deformation. Adjusting components are provided at both ends of the elastic bladder. The adjusting components are arranged at both ends of the elastic bladder, can wrap the elastic bladder, and the distance between the two adjusting components can be adjusted to change the surface area of the elastic bladder wrapped by the adjusting components.

[0006] The adjustment assembly is composed of a control ring and a moving ring. The control ring and the moving ring are arranged at both ends of the elastic capsule. An electromagnetic module is provided on the control ring, and a permanent magnet is provided on the moving ring. By energizing the electromagnetic module to generate a magnetic field that is the same as or different from that of the permanent magnet, the moving ring drives one end of the elastic capsule to move.

[0007] The moving ring is fixed on the wall surface of the pump body groove and is on the same wall surface as the peristaltic pump.

[0008] The control ring is in the shape of a sleeve and is arranged outside the elastic capsule. An elliptical disc is provided at one end of the control ring close to the moving ring, and the electromagnetic module is arranged on the disc. The shape of the moving ring is the same as that of the disc.

[0009] There are two electromagnetic modules in total, which are respectively located above and below the elastic capsule. The number and position of the permanent magnets correspond to those of the electromagnetic modules.

[0010] The electromagnetic module is in the shape of a circular ring and is arranged outside the elastic capsule. The shape and position of the permanent magnet correspond to those of the electromagnetic module.

[0011] A ring-shaped positioning protrusion is provided on the outer surface of the elastic capsule, and depressions with the same shape as the positioning protrusion are provided on the inner sides of the control ring and the moving ring.

[0012] The adjustment assembly is composed of a control ring and a moving ring. The control ring and the moving ring are in a sleeve structure. Threads are provided on the outer side of the control ring. By rotating the control ring, the distance between the control ring and the moving ring can be changed.

[0013] Both the elastic capsule and the hose are made of food-grade silica gel.

[0014] (III)Advantages: Compared with the prior art, the present invention provides a peristaltic discharging anti-pulse backflow precise discharging structure, which has the following advantages: 1. In this peristaltic discharging anti-pulse backflow precise discharging structure, the peristaltic pump pumps fluid by alternately squeezing and releasing the hose with rollers. This working method will generate periodic pressure fluctuations in the hose, namely the pulse phenomenon. The elastic bladder, as a key component in the fluid delivery system, is designed to absorb and relieve these pulse pressures. When the peristaltic pump roller squeezes the hose, the pressure inside the hose increases, and the elastic bladder will be compressed, storing the excess fluid and pressure. In this process, the elastic bladder acts as a "pressure absorber", effectively reducing the pressure fluctuations during fluid delivery. When the peristaltic pump roller releases the hose, the pressure inside the hose decreases, and the elastic bladder will release the previously stored fluid and pressure, thus smoothing the fluid flow and preventing the flow instability caused by sudden pressure changes. When the peristaltic pump stops working, due to the gravity and inertia of the liquid in the hose, dripping usually occurs at the water outlet. The design of the elastic bladder allows it to deform when the peristaltic pump stops. Especially when the bladder is stretched (such as controlled by the adjustment component), its volume will increase. During this process, a negative pressure area will be formed inside the elastic bladder, that is, an area where the pressure is lower than the external environmental pressure. The existence of the negative pressure area can generate a "backflow" effect, that is, attracting the beverage in the hose to flow towards the elastic bladder direction, thus preventing it from dripping at the water outlet. The adjustment component plays a crucial role in the deformation and backflow process of the elastic bladder. By adjusting the parameters of the adjustment component (such as the stretching degree, recovery speed, etc.), the deformation degree of the elastic bladder and the size of the negative pressure area can be precisely controlled, thereby optimizing the backflow effect and the uniform outflow of the beverage. In addition, the adjustment component can also adjust the volume and elasticity of the elastic bladder according to actual needs to adapt to the changes in different beverage types and flow requirements.

[0015] 2. This peristaltic discharging anti-pulse back-suction precise discharging structure can achieve precise control of the control ring through the interaction between the magnetic field generated by the electromagnetic module and the permanent magnet. This non-contact control method not only reduces mechanical wear but also improves the control accuracy and response speed. During the operation of the beverage machine, the deformation degree of the elastic bladder and the size of the negative pressure area can be dynamically adjusted according to actual needs. For example, when the peristaltic pump stops working, the position of the control ring can be quickly adjusted to make the elastic bladder generate sufficient negative pressure to effectively prevent beverage dripping; when the peristaltic pump resumes work, the position of the control ring can be quickly adjusted again to make the elastic bladder return to its original state and absorb the pulsating pressure. Since the non-contact electromagnetic control method is adopted, mechanical failures and wear problems that may occur in the traditional mechanical adjustment method are avoided, improving the stability and reliability of the system. This structure can adapt to changes in different beverage types and flow requirements. By adjusting the magnitude and direction of the current in the electromagnetic module, the magnetic field strength can be changed, thereby achieving precise control of the moving speed and distance of the control ring to meet the needs of different beverage deliveries.

[0016] 3. This peristaltic discharging anti-pulse back-suction precise discharging structure has two electromagnetic modules, which are respectively located above and below the elastic bladder. The number and position of the permanent magnets correspond to those of the electromagnetic modules. Since the electromagnetic modules are respectively located above and below the elastic bladder, bidirectional control of both ends of the elastic bladder can be achieved. This control method is more flexible and can adjust the deformation degrees of the upper and lower ends of the elastic bladder simultaneously or separately according to needs, thereby achieving more precise regulation of the beverage flow rate.

[0017] 4. This peristaltic discharging anti-pulse back-suction precise discharging structure has a circular electromagnetic module arranged outside the elastic bladder. The shape and position of the permanent magnet correspond to those of the electromagnetic module. The circular electromagnetic module can achieve uniform control of the entire circumference of the elastic bladder. This control method can ensure better uniformity and stability of the elastic bladder during deformation, avoiding problems such as unstable fluid delivery or mechanical failures caused by local excessive deformation. Since the electromagnetic module is circular and arranged outside the elastic bladder, the space in the pump body groove can be fully utilized, reducing unnecessary waste and occupied space. This compact structure design makes the volume of the entire beverage machine smaller and the structure more compact.

[0018] 5. The peristaltic discharging anti-pulse back-suction precise discharging structure can ensure the precise positions of the control ring and the moving ring on the elastic bladder through the cooperation of the positioning protrusions and depressions. This positioning method not only improves the assembly accuracy but also ensures that the control ring and the moving ring will not be displaced due to vibration or external forces during operation, thus guaranteeing the stability and reliability of the beverage machine. Through the tight cooperation of the positioning protrusions and depressions, a stable connection between the control ring, the moving ring, and the elastic bladder can be achieved. This connection method not only enhances the integrity of the structure but also improves the connection strength between components, enabling the beverage machine to maintain good working performance even when subjected to large pressures or tensile forces.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1: Please refer to Figures 1 - 4 , a peristaltic discharging anti-pulse back-suction precise discharging structure, including a beverage machine body 1. A refrigerating cabinet 11 for placing beverages is provided at the bottom of the beverage machine body 1. A pump body groove 12 is provided on the tabletop of the beverage machine body 1. A peristaltic pump 121 is provided in the pump body groove 12. A hose 125 is connected between the peristaltic pump 121 and the cold drink placed in the refrigerating cabinet 11. An outlet 13 is provided on the side of the pump body groove 12. The peristaltic pump 121 is connected to the outlet 13 through the hose 125 to realize the transportation of the beverage from the refrigerating cabinet 11 to the outlet 13. An elastic bladder 122 is provided on the hose 125 between the peristaltic pump 121 and the outlet 13. After the beverage flows to the peristaltic pump 121, it first flows into the elastic bladder 122 and then flows to the outlet 13. The elastic bladder 122 has elasticity and can generate a certain deformation. Adjusting components are provided at both ends of the elastic bladder 122. The adjusting components are arranged at both ends of the elastic bladder 122. The adjusting components can wrap the elastic bladder 122, and the distance between the two adjusting components can be adjusted to change the surface area of the elastic bladder 122 wrapped by the adjusting components.

[0030] The water outlet 13 is connected to the peristaltic pump 121 through a hose 125. The peristaltic pump 121 pumps the beverage out of the refrigerator 11 by squeezing and releasing the hose 125. When the peristaltic pump 121 stops working, due to the influence of its own gravity and inertia, the liquid in the hose 125 will drip at the water outlet 13. The working principle of the peristaltic pump 121 is to pump fluid by alternately squeezing and releasing the hose 125 with rollers. When the pump stops working, the pressure on the hose 125 disappears. However, since the elastic tension of the hose 125 itself is less than the downward force of the liquid, including the force generated by gravity and ductility, the liquid will still continue to drip. And when the peristaltic pump 121 works, due to the squeezing and releasing of the hose 125 by the rollers, a pulsation phenomenon will occur. An elastic bladder 122 is provided at the hose 125 connecting the peristaltic pump 121 and the water outlet 13. The elastic bladder 122 can serve as a flexible liquid storage or buffer device, capable of coping with the flow rate fluctuations during fluid transportation, making the entire transportation system more stable. The elastic bladder 122 has a certain elasticity, which can absorb and relieve the pulsation pressure generated during the operation of the peristaltic pump 121, protect the hose 125 from the influence of excessive pressure, and extend the service life of the hose 125. By adjusting the volume and elasticity of the elastic bladder 122, the transportation speed and pressure of the fluid can be conveniently controlled. During the working process, the change in the volume of the elastic bladder 122 can back-suck the beverage in the hose 125 directly between the elastic bladder 122 and the water outlet 13 to prevent dripping. By adjusting the wrapping effect of the adjusting component on the elastic bladder 122, the deformation of the elastic bladder 122 can be restricted. When the peristaltic pump 121 finishes working, increasing the distance between the two adjusting components means that the surface area of the elastic bladder 122 not wrapped by the adjusting component increases, making the deformation amount that the elastic bladder 122 can generate increase, the volume increases, and back-suction occurs, absorbing part of the liquid in the hose after the elastic bladder 122, so that the liquid level about to drip at the water outlet 13 can generate an upward displacement. At the same time, because the deformation amount is limited, the upward displacement will not be too large, effectively avoiding excessive air contact with the internal pipeline of the water outlet, resulting in bacterial contamination. The increase in volume can generate negative pressure when the peristaltic pump 121 stops working, back-sucking the beverage in the hose 125 between the elastic bladder 122 and the water outlet 13 to avoid dripping. After the peristaltic pump 121 resumes working, making the adjusting component and the elastic bladder 122 return to their original state can absorb the pulsation while buffering the originally intermittently flowing beverage in the elastic bladder 122, enabling it to flow out evenly from the water outlet 13.

[0031] See Figures 3 - 4, the adjustment assembly consists of a control ring 123 and a moving ring 124. The control ring 123 and the moving ring 124 are arranged at both ends of the elastic bladder 122. An electromagnetic module 1231 is provided on the control ring 123, and a permanent magnet 1232 is provided on the moving ring 124. By connecting the electromagnetic module 1231 to an electric circuit to generate a magnetic field that is the same as or different from that of the permanent magnet 1232, the control ring 124 is caused to move. The moving ring 123 is fixed to the wall surface of the pump body groove 12 and is on the same wall surface as the peristaltic pump 121. The control ring 123 is in the shape of a sleeve and is arranged outside the elastic bladder 122. By moving the control ring 123 on the surface of the elastic bladder 122, the surface area wrapped by the control ring 123 can be changed. One end of the control ring 123 close to the moving ring 124 is provided with an elliptical disc, and the electromagnetic module 1231 is arranged on the disc. The shape of the moving ring 124 is the same as that of the disc.

[0032] There are two electromagnetic modules 1231 in total, which are respectively located above and below the elastic bladder 122. The number and position of the permanent magnets 1232 are corresponding to those of the electromagnetic modules 1231. Since the electromagnetic modules 1231 are respectively located above and below the elastic bladder 122, two-way control of both ends of the elastic bladder 122 can be achieved. This control method is more flexible and can adjust the deformation degrees of the upper and lower ends of the elastic bladder 122 simultaneously or separately as needed, so as to achieve more precise regulation of the beverage flow rate.

[0033] Refer to Figure 7 , a ring-shaped positioning protrusion 1221 is provided on the outer surface of the elastic bladder 122, and depressions having the same shape as the positioning protrusion 1221 are provided on the inner sides of the control ring 123 and the moving ring 124.

[0034] Both the elastic bladder 122 and the hose 125 are made of food-grade silica gel.

[0035] Embodiment 2: Please refer to Figures 1 - 2 and Figures 5 - 6, the peristaltic discharging anti-pulse back-suction precise discharging structure, including the beverage machine body 1, a refrigerator 11 for placing beverages is provided at the bottom of the beverage machine body 1, a pump body groove 12 is provided on the tabletop of the beverage machine body 1, a peristaltic pump 121 is provided in the pump body groove 12, a hose 125 is connected between the peristaltic pump 121 and the cold drink placed in the refrigerator 11, a water outlet 13 is provided on the side of the pump body groove 12, and the peristaltic pump 121 is connected to the water outlet 13 through the hose 125, so as to transport the beverage from the refrigerator 11 to the water outlet 13. An elastic bladder 122 is provided on the hose 125 between the peristaltic pump 121 and the water outlet 13. After the beverage flows to the peristaltic pump 121, it first flows into the elastic bladder 122 and then flows to the water outlet 13. The elastic bladder 122 has elasticity and can generate a certain deformation. Adjusting components are provided at both ends of the elastic bladder 122. The adjusting components are arranged at both ends of the elastic bladder 122. The adjusting components can wrap the elastic bladder 122, and the distance between the two adjusting components can be adjusted to change the surface area of the elastic bladder 122 wrapped by the adjusting components.

[0036] The water outlet 13 is connected to the peristaltic pump 121 through a hose 125. The peristaltic pump 121 pumps and releases the hose 125 to draw the beverage out of the refrigerator 11 and transport it to the water outlet 13. When the peristaltic pump 121 stops working, due to the influence of its own gravity and inertia, the liquid in the hose 125 will drip at the water outlet 13. The working principle of the peristaltic pump 121 is to pump the fluid by alternately squeezing and releasing the hose 125 with rollers. When the pump stops working, the pressure on the hose 125 disappears. However, since the elastic tension of the hose 125 itself is less than the downward force of the liquid, including the force generated by gravity and ductility, the liquid will still continue to drip. And when the peristaltic pump 121 is working, due to the squeezing and releasing of the hose 125 by the rollers, a pulsation phenomenon will occur. An elastic bladder 122 is provided at the hose 125 connecting the peristaltic pump 121 and the water outlet 13. The elastic bladder 122 can act as a flexible liquid storage or buffer device, capable of coping with the flow fluctuations during fluid transportation, making the entire transportation system more stable. The elastic bladder 122 has a certain elasticity and can absorb and relieve the pulsation pressure generated during the operation of the peristaltic pump 121, protecting the hose 125 from the influence of excessive pressure and extending the service life of the hose 125. By adjusting the volume and elasticity of the elastic bladder 122, the transportation speed and pressure of the fluid can be conveniently controlled. During the working process, the change in the volume of the elastic bladder 122 can back-suck the beverage in the hose 125 directly between the elastic bladder 122 and the water outlet 13 to prevent dripping. By adjusting the wrapping effect of the adjusting component on the elastic bladder 122, the deformation of the elastic bladder 122 can be restricted. After the peristaltic pump 121 finishes working, increasing the distance between the two adjusting components indicates that the surface area of the elastic bladder 122 not wrapped by the adjusting component increases, making the deformation amount that the elastic bladder 122 can generate increase, the volume increases, and back-suction occurs, absorbing part of the liquid in the hose after the elastic bladder 122, so that the liquid level about to drip at the water outlet 13 can generate an upward displacement. At the same time, because the deformation amount is limited, the upward displacement will not be too large, effectively avoiding excessive air contact with the internal pipeline of the water outlet, resulting in bacterial contamination. The increase in volume can generate a negative pressure when the peristaltic pump 121 stops working, back-sucking the beverage in the hose 125 between the elastic bladder 122 and the water outlet 13 to avoid dripping. After the peristaltic pump 121 resumes working, making the adjusting component and the elastic bladder 122 return to their original state can absorb the pulsation while buffering the originally intermittently flowing beverage in the elastic bladder 122, enabling it to flow out evenly from the water outlet 13.

[0037] Refer to Figures 5 - 6, the adjustment assembly is composed of a control ring 123 and a moving ring 124. The control ring 123 and the moving ring 124 are arranged at both ends of the elastic bladder 122. An electromagnetic module 1231 is provided on the control ring 123, and a permanent magnet 1232 is provided on the moving ring 124. By energizing the electromagnetic module 1231 to generate a magnetic field that is the same as or different from that of the permanent magnet 1232, the control ring 124 can be moved. The moving ring 123 is fixed on the wall surface of the pump body groove 12 and is arranged on the same wall surface as the peristaltic pump 121. The control ring 123 is in the shape of a sleeve and is arranged outside the elastic bladder 122. By moving the control ring 123 on the surface of the elastic bladder 122, the surface area wrapped by the control ring 123 can be changed. An elliptical disc is provided at one end of the control ring 123 close to the moving ring 124, and the electromagnetic module 1231 is arranged on the disc. The shape of the moving ring 124 is the same as that of the disc.

[0038] The electromagnetic module 1231 is circular and is arranged outside the elastic bladder 122. The shape and position of the permanent magnet 1232 correspond to those of the electromagnetic module 1231. The circular electromagnetic module 1231 can achieve uniform control over the entire circumference of the elastic bladder 122. This control method can ensure that the elastic bladder 122 maintains good uniformity and stability during the deformation process, avoiding problems such as unstable fluid transportation or mechanical failures caused by local excessive deformation. Since the electromagnetic module 1231 is circular and is arranged outside the elastic bladder 122, the space inside the pump body groove 12 can be fully utilized, reducing unnecessary waste and occupied space. This compact structural design makes the entire beverage machine smaller in volume and more compact in structure.

[0039] Refer to Figure 7 , a ring-shaped positioning protrusion 1221 is provided on the outer surface of the elastic bladder 122, and depressions having the same shape as the positioning protrusion 1221 are provided on the inner sides of the control ring 123 and the moving ring 124.

[0040] Both the elastic bladder 122 and the hose 125 are made of food-grade silicone.

[0041] In other embodiments, refer to Figure 8 , the adjustment assembly is composed of a control ring 123 and a moving ring 124. The control ring 123 and the moving ring 124 are in a sleeve structure. Threads are provided on the outer side of the control ring 123. By rotating the control ring 123, the distance between the control ring 123 and the moving ring 124 can be changed.

[0042] Working principle: The water outlet 13 is connected to the peristaltic pump 121 through a hose 125. The peristaltic pump 121 pumps the beverage out of the refrigerator 11 by squeezing and releasing the hose 125. When the peristaltic pump 121 stops working, due to the gravity and inertia of the liquid in the hose 125, dripping will occur at the water outlet 13. The working principle of the peristaltic pump 121 is to pump fluid by alternately squeezing and releasing the hose 125 with rollers. When the pump stops working, the pressure on the hose 125 disappears. However, since the elastic tension of the hose 125 itself is less than the downward force of the liquid, including the force generated by gravity and ductility, the liquid will still continue to drip. And when the peristaltic pump 121 is working, due to the squeezing and releasing of the hose 125 by the rollers, a pulsation phenomenon will occur. An elastic bladder 122 is provided at the hose 125 connecting the peristaltic pump 121 and the water outlet 13. The elastic bladder 122 can serve as a flexible liquid storage or buffer device, capable of coping with the flow fluctuations during fluid transportation, making the entire transportation system more stable. The elastic bladder 122 has a certain elasticity, which can absorb and relieve the pulsation pressure generated during the operation of the peristaltic pump 121, protect the hose 125 from excessive pressure, and extend the service life of the hose 125. By adjusting the volume and elasticity of the elastic bladder 122, the transportation speed and pressure of the fluid can be conveniently controlled. During the working process, the change in the volume of the elastic bladder 122 can back-suck the beverage in the hose 125 directly between the elastic bladder 122 and the water outlet 13 to prevent dripping. By adjusting the wrapping effect of the adjusting component on the elastic bladder 122, the deformation of the elastic bladder 122 can be restricted. After the peristaltic pump 121 finishes working, increasing the distance between the two adjusting components means that the surface area of the elastic bladder 122 not wrapped by the adjusting component increases, enabling the elastic bladder 122 to generate a larger deformation amount and an increased volume, resulting in back-sucking, absorbing part of the liquid in the hose after the elastic bladder 122, causing the liquid level about to drip at the water outlet 13 to generate an upward displacement. At the same time, because the deformation amount is limited, the upward displacement will not be too large, effectively avoiding excessive air contact with the internal pipeline of the water outlet, resulting in bacterial contamination. The increase in volume can generate a negative pressure when the peristaltic pump 121 stops working, back-sucking the beverage in the hose 125 between the elastic bladder 122 and the water outlet 13 to avoid dripping. After the peristaltic pump 121 resumes working, restoring the adjusting component and the elastic bladder 122 to their original state can absorb the pulsation while buffering the originally intermittently flowing beverage in the elastic bladder 122, enabling it to flow out evenly from the water outlet 13.
