Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and in particular to a peristaltic pump assembly. Background Technology

[0002] A peristaltic pump is a pump that delivers fluid by squeezing a hose. It mainly consists of a driver, a hose, and rollers. When it is working, the rollers roll along the inner surface of the hose. As the rollers roll, they flatten the hose, thus preventing the fluid in the part of the hose in front of the rollers from flowing. Meanwhile, the part of the hose behind the rollers gradually returns to its original shape, creating a vacuum, which allows the fluid to be drawn into the hose at the inlet.

[0003] Currently, many industries require the mixing of various solutions. For example, in the hairdressing industry, when performing hair softening or hair repair operations, it is often necessary to mix solutions with different properties in a certain proportion. Another example is the bartending industry, which requires the blending of various types of beverages in a specific ratio. Traditional peristaltic pumps can usually only stably deliver a single flow rate of solution, making it difficult to meet the mixing needs of different flow rates and types of solutions at the same time. Utility Model Content

[0005] To achieve the above objectives, the peristaltic pump assembly proposed in this utility model...

[0006] The driver has at least two output terminals, and the output power of the two output terminals is adjustable;

[0007] Pump body, one pump body corresponding to each output end, the pump body includes a pump casing and a turntable, the turntable is disposed inside the pump casing and forms a channel with the inner wall of the pump casing, and the output end of the driver is driven and connected to the turntable; and

[0008] A hose is provided for each of the channels to be squeezed by the rotation of the turntable. One end of the hose is connected to a first connector and the other end of the hose is connected to a second connector. Both the first connector and the second connector are located outside the pump housing.

[0009] In one embodiment, the driver includes a motor and a gearbox. At least two motors are provided, and at least two planetary gear sets are provided inside the gearbox. Each motor is driven and connected to one of the planetary gear sets, and the end of the planetary gear set away from the motor is driven and connected to the turntable.

[0010] In one embodiment, the motor has a rotating shaft, and the peristaltic pump assembly includes a controller and a speed detection component. Each motor is provided with one speed detection component, and the controller is communicatively connected to the motor. The speed detection component includes:

[0011] The mounting base is coaxially connected to the rotating shaft;

[0012] A triggering element is disposed on the mounting base and rotates synchronously with the mounting base;

[0013] A detection sensor is communicatively connected to the input terminal of the controller. The detection sensor is used to detect the trigger element and transmit a signal to the controller so that the controller adjusts the output speed of the motor.

[0014] In one embodiment, the triggering element is configured with a reflector, which is mounted on the end of the mounting base away from the motor, and the detection sensor is configured as a grating sensor.

[0015] In one embodiment, the mounting base has a mounting groove at the end away from the motor. There are two mounting grooves, which are symmetrically arranged on the mounting base. The reflector is disposed in the mounting groove.

[0016] In one embodiment, the triggering element is configured as a magnet, and the detection sensor is configured as a Hall sensor.

[0017] In one embodiment, the speed detection component further includes a counterweight, which is symmetrically arranged with respect to the magnet.

[0018] In one embodiment, the pump housing includes an upper cover and a lower cover, which are connected together to form an installation cavity. The turntable is installed in the installation cavity. The turntable includes a bracket and rollers disposed on the bracket. The motor is connected to the bracket through the planetary gear set to drive the rollers to rotate, so that the rollers squeeze the hose in the channel.

[0019] In one embodiment, the first connector includes a first tube body and a first connecting portion, the first tube body is connected to the first connecting portion and bent, the first connecting portion is connected to one end of the hose, and the first connecting portion is rotatably connected to the hose;

[0020] And / or, the second connector includes a second tube body and a second connecting part, the second tube body communicating with and being bent to connect the second connecting part, the second connecting part communicating with one end of the hose, and the second connecting part being rotatably connected to the hose.

[0021] In one embodiment, a seal is provided at the connection between the first connector and / or the second connector and the hose.

[0022] In this invention, the peristaltic pump assembly includes a driver connected to the pump body. The driver drives a rotating disc within the pump body to rotate, causing the disc to compress a flexible tube within the pump body. The flexible tube is connected to a liquid source via either a first or second connector, serving as an inlet port. The other connector serves as an outlet port. When the disc is in its initial position within the pump housing and not rotating, the flexible tube is not compressed. At this time, the internal cavity of the flexible tube is relatively large. After the liquid enters the flexible tube, as the disc rotates, it pushes the liquid forward, causing the liquid to flow along the flexible tube in the discharge direction. When the flexible tube is compressed to a certain extent, the liquid at the outlet port is squeezed out, completing the discharge process. The process involves the continuous squeezing and releasing of the hose as the turntable rotates, thereby continuously drawing in and expelling liquid, allowing the liquid to flow continuously inside the hose. Since the driver has multiple output ends, each output end corresponds to a pump body, and each pump body has a corresponding hose. The inlet port of each hose can be connected to the same type of liquid or different types of liquid. When the same type of liquid is connected, activating the driver can increase the output volume at the same time. If different types of liquid are connected, when the driver is activated, the turntable in each pump body squeezes its respective hose, and the liquid in each pump body is squeezed out, thereby realizing the simultaneous delivery of multiple solutions and the mixing of multiple solutions.

[0037] A peristaltic pump is a pump that delivers fluid by squeezing a hose. It mainly consists of a driver, a hose, and rollers. When it is working, the rollers roll along the inner surface of the hose. As the rollers roll, they flatten the hose, thus preventing the fluid in the part of the hose in front of the rollers from flowing. Meanwhile, the part of the hose behind the rollers gradually returns to its original shape, creating a vacuum, which allows the fluid to be drawn into the hose at the inlet.

[0038] Currently, many industries require the mixing of various solutions. For example, in the hairdressing industry, when performing hair softening or hair repair operations, it is often necessary to mix solutions with different properties in a certain proportion. Another example is the bartending industry, which requires the blending of various types of beverages in a specific ratio. Traditional peristaltic pumps can usually only stably deliver a single flow rate of solution, making it difficult to meet the mixing needs of different flow rates and types of solutions at the same time.

[0039] This utility model proposes a peristaltic pump.

[0040] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the peristaltic pump includes a driver 100, a pump body 200, and a hose 300. The driver 100 has at least two output ends 101, and the output power of the two output ends 101 is adjustable. Each output end 101 is correspondingly provided with a pump body 200. The pump body 200 includes a pump housing 210 and a turntable 220. The turntable 220 is disposed inside the pump housing 210 and forms a channel with the inner wall of the pump housing 210. The output end 101 of the driver 100 drives and connects to the turntable 220. Each channel is correspondingly provided with a hose 300, so that the hose 300 is squeezed by the rotation of the turntable 220. One end of the hose 300 is connected to a first connector 310, and the other end of the hose 300 is connected to a second connector 320. Both the first connector 310 and the second connector 320 are disposed outside the pump housing 210.

[0041] In the technical solution of this utility model, the peristaltic pump assembly includes a driver 100, which is connected to the pump body 200 and drives the turntable 220 inside the pump body 200 to rotate. This causes the turntable 220 to compress the hose 300 inside the pump body 200. The hose 300 is connected to a liquid source through either a first connector 310 or a second connector 320, serving as an inlet port. The other connector serves as an outlet port. When the turntable 220 is not rotating at its initial position inside the pump housing 210, the hose 300 is in an uncompressed state. At this time, the internal cavity space of the hose 300 is relatively large. After the liquid enters the hose 300, as the turntable 220 rotates, it pushes the liquid forward, causing the liquid to flow along the hose 300 in the discharge direction. When the hose 300 is compressed to a certain extent, the liquid at the outlet port... The liquid is squeezed to the outside, completing the liquid discharge process. As the turntable 220 rotates, the hose 300 is continuously squeezed and released, thereby continuously drawing in and discharging liquid, allowing the liquid to flow continuously inside the hose 300. Since the driver 100 has multiple output ends 101, each output end 101 corresponds to a pump body 200, and each pump body 200 is equipped with a hose 300. The liquid inlet port of each hose 300 can be connected to the same type of liquid or different types of liquid. When the same type of liquid is connected, starting the driver 100 can increase the liquid discharge volume at the same time. If different types of liquid are connected, when the driver 100 is started, the turntable 220 in each pump body 200 squeezes its respective hose 300, and the liquid in each pump body 200 is squeezed out, thereby realizing the simultaneous delivery of multiple solutions and thus realizing the mixing of multiple solutions.

[0042] Specifically, the driver 100 has two output terminals 101, each with adjustable power. For example, the motor 110 adjusts the speed of its shaft to adjust the power, thereby regulating the liquid output speed and flow rate, and thus adjusting the mixing ratio of various solutions. The pump body 200 includes a pump housing 210 and a turntable 220. The turntable 220 is inside the pump housing 210 and forms a channel with the inner wall of the pump housing 210. The hose 300 is disposed in the channel. The pump housing 210 has openings corresponding to the two ends of the hose 300. The first connector 310 extends into one of the openings and communicates with the hose 300. The second connector 320 extends into the other opening and communicates with the other end of the hose 300, thereby enabling liquid to enter the hose 300 and flow out of the hose 300 to achieve continuous liquid delivery. In one embodiment, the hose 300 can be made of rubber or plastic dynamic material. When the turntable 220 squeezes the hose 300, the hose 300 undergoes elastic deformation, and the inner cavity of the hose 300 is compressed and reduced. When the turntable 220 leaves the squeezed area, the hose 300 rebounds and returns to its original shape, forming a negative pressure, which in turn draws liquid into the hose 300. As the turntable 220 rotates, it pushes the liquid in the hose 300 forward, that is, towards the liquid outlet. With the continuous rotation of the turntable 220, the liquid continues to flow in the hose 300.

[0043] Optionally, in an embodiment of the present invention, the driver 100 includes a motor 110 and a gearbox 120. At least two motors 110 are provided, and at least two planetary gear sets are provided inside the gearbox 120. Each motor 110 is driven and connected to a planetary gear set, and the end of the planetary gear set away from the motor 110 is driven and connected to the turntable 220.

[0044] Please refer to Figure 4 The gearbox 120 is an integrated structure, containing multiple planetary gear sets. Each planetary gear set is connected to a motor 110, and the other end is connected to the turntable 220 of the corresponding pump body 200, so that one motor 110 drives one turntable 220 to rotate. The gearbox 120 ensures high efficiency and coaxiality of power transmission, and the speed of each motor 110 can be adjusted individually, thereby adjusting the power of each output end 101 and the liquid discharge speed of each pump body 200. The multiple pump bodies 200 and the gearbox 120 are arranged compactly, making the entire peristaltic pump set an integrated structure. While achieving solution mixing, it also saves the installation space of the peristaltic pump set, has a wide range of applications, a compact structure, and can also improve the power transmission efficiency of the motor 110.

[0045] In an embodiment of this utility model, the motor 110 has a rotating shaft 111, and the peristaltic pump assembly includes a controller and a speed detection component 400. Each motor 110 is provided with a corresponding speed detection component 400. The controller is communicatively connected to the motor 110, and the speed detection component 400 includes:

[0046] Mounting base 410 is coaxially connected to rotating shaft 111;

[0047] A triggering element is provided on the mounting base 410 and rotates synchronously with the mounting base 410;

[0048] The detection sensor is connected to the input terminal of the controller. The detection sensor is used to detect the trigger element and transmit signals to the controller so that the controller can adjust the output speed of the motor 110.

[0049] Please refer to Figure 2 and Figure 3 The motor 110's rotating shaft 111 is coaxially connected to the mounting base 410, allowing the mounting base 410 to rotate synchronously with the turntable 220. A trigger element is mounted on the mounting base 410, and a detection sensor detects the trigger element. The trigger element rotates together with the rotating shaft 111 on the mounting base 410. Each time the detection sensor detects the trigger element, it sends a signal to the controller, which then controls the speed of the motor 110 to control the liquid output flow rate. Each motor 110 is equipped with a corresponding speed detection component 400, which can detect the speed of each motor 110 individually and monitor each motor 110 and the pump body 200 in real time. By setting a controller to individually control the speed and running time of each motor 110, different solutions are delivered and precisely mixed according to a set ratio and sequence, ensuring the quality of solution mixing. The speed of the motor 110 can also be adjusted in real time according to actual temporary needs, realizing dynamic mixing control and improving the working efficiency of the peristaltic pump group.

[0050] In one embodiment, please refer to Figure 2 The mounting base 410 has a cylindrical structure. This cylindrical structure reduces the resistance to rotation, allowing for more accurate detection of the trigger element by the sensor and thus obtaining the motor 110 speed. In another embodiment, please refer to... Figure 3 The mounting base 410 can also adopt a frustum structure, that is, the diameter of the end of the mounting base 410 closer to the motor 110 is larger than the diameter of the end farther away from the motor 110, which is not restricted here.

[0051] In this embodiment of the invention, the triggering element is configured with a reflector 420, which is mounted on the end of the mounting base 410 away from the motor 110. The detection sensor is configured as a grating sensor. The reflector 420 rotates on the mounting base 410 along with the shaft 111 of the motor 110, that is, it rotates with the turntable 220. The light source of the grating sensor emits light towards the mounting base 410, and the reflector 420 is used for reflection. When the reflector 420 rotates to reflect all the light, the reflected light is received by the photodetector on the grating sensor and converted into an electrical signal, which is transmitted to the controller. The photodetector generates an electrical signal each time it receives a light signal. The controller calculates the speed of the motor 110 based on the received signal. The speed of the reflector 420 is proportional to the number of electrical signals. The speed of the motor 110 is adjusted and controlled by PID control to output different flow rates.

[0052] Optionally, in one embodiment, a mounting groove is provided at the end of the mounting base 410 away from the motor 110. Two mounting grooves are provided and symmetrically arranged on the mounting base 410. The reflector 420 is disposed in the mounting groove. By symmetrically arranging two reflectors 420 on the mounting base 410, the weight on both sides of the mounting base 410 can be balanced, ensuring that the mounting base 410 is in a dynamic balance state when rotating, avoiding irreversible shaft damage caused by excessive centrifugal force during rotation. Furthermore, the mounting groove is provided at the position where the reflector 420 is installed on the mounting base 410. The reflector 420 can be installed in the mounting groove by means of adhesive or snap-fit, which can avoid the reflector 420 protruding on the mounting base 410 and causing damage to the reflector 420.

[0053] It should be noted that since there are two reflectors 420 set symmetrically, the number of reflectors 420 detected by the grating sensor is doubled, and the corresponding adjustment is made when calculating the speed of motor 110.

[0054] In this embodiment of the invention, the triggering element is configured as a magnet 430, and the detection sensor is configured as a Hall sensor. The magnet 430 can be mounted on the mounting base 410 by means of bonding or other methods. The magnet 430 can generate a magnetic field. When the rotating shaft 111 rotates, the mounting base 410 rotates together with the rotating shaft 111. The Hall sensor generates a corresponding electrical signal by detecting the change in the magnetic field of the magnet 430 to measure the rotational speed of the motor 110. Then, the controller compares the detected rotational speed with the preset speed and adjusts the rotational speed of the motor 110 through PID control to output different flow rates.

[0055] In an embodiment of this utility model, the speed detection component 400 further includes a counterweight 440, which is symmetrically arranged with the magnet 430. Accordingly, the mounting base 410 can be in a dynamic balance state during rotation, avoiding irreversible shaft damage caused by excessive centrifugal force during rotation.

[0056] In the embodiments of this utility model, please refer to Figure 4 The pump housing 210 includes an upper cover 211 and a lower cover 212, which are connected to form an installation cavity. A turntable 220 is installed in the installation cavity. The turntable 220 includes a bracket 221 and a roller 222 mounted on the bracket 221. A motor 110 is connected to the bracket 221 via a planetary gear set to drive the roller 222 to rotate, causing the roller 222 to compress the hose 300 in the channel. The pump housing 210 can adopt a structure with an upper cover 211 and a lower cover 212. The upper cover 211 and the lower cover 212 are connected by screws, and the upper cover 211 and the lower cover 212 are connected by screws. An installation cavity is formed between the two, and the inner wall of the installation cavity abuts against the turntable 220. As the turntable 220 rotates, the hose 300 is squeezed in the installation cavity. The turntable 220 includes a bracket 221, on which rollers 222 are arranged circumferentially. Preferably, three rollers 222 are arranged on the bracket 221. The bracket 221 is connected to a planetary gear set to realize the rotation of the bracket 221 and the rollers 222 on the bracket 221. The rollers 222 squeeze the hose 300 in the channel while rotating, pushing the liquid in the hose 300 towards the liquid outlet port.

[0057] It should be noted that the pump housings 210 of multiple pump bodies 200 can be integrated into a whole, that is, a top cover 211 and a bottom cover 212 are provided to form an installation cavity. Multiple chambers are independently set in the installation cavity, and each chamber is provided with a turntable 220 and a corresponding channel is formed to place the hose 300. This can realize the delivery of various solutions and reduce the footprint of the pump body 200, which is conducive to the lightweight structure.

[0058] In the embodiments of this utility model, please refer to Figure 4 The first connector 310 includes a first tube body and a first connecting part. The first tube body is connected to the first connecting part and bent. The first connecting part is connected to one end of the hose 300 and is rotatably connected to the hose 300. The first tube body is connected to one end of the hose 300 through the first connecting part. One end of the first connecting part is integrally formed and connected to the first tube body, and the other end is inserted into the hose 300. The first tube body can rotate relative to the hose 300 through the first connecting part. That is, the first connector 310 can rotate 360° with the end of the hose 300 as the central axis to adapt to different liquid inflow / outflow directions, ensure that the flow resistance of the liquid is minimized when entering and exiting the pump body 200, and facilitate smoother liquid delivery in the hose 300.

[0059] In one embodiment, the second connector 320 has the same structure as the first connector 310. The second connector 320 includes a second tube body and a second connecting part. The second tube body and the second connecting part are connected and bent. The second connecting part is connected to one end of the hose 300 and is rotatably connected to the hose 300. The second connector 320 and the first connector 310 are installed at both ends of the hose 300. By rotating the first connector 310 and the second connector 320, different inflow and outflow directions of liquid can be achieved, reducing the retention of liquid in the hose 300 and making liquid transportation more efficient.

[0060] In the embodiments of this utility model, please refer to Figure 4 A sealing element 330 is provided at the connection between the first connector 310 and / or the second connector 320 and the hose 300. That is, a sealing element 330 is provided at the end of the first connector away from the first tube body. When the first connector is inserted into the hose 300, the sealing element 330 seals the connection between the first connector and the hose 300 to prevent liquid from leaking when it flows into the hose 300. The same applies to the second connector 320 to prevent liquid from leaking when it flows out of the hose 300.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model.
