Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and more specifically to a modular peristaltic pump and equipment. Background Technology

[0002] Peristaltic pumps are used to pump flowing liquids. Their design typically involves fixing the pump within a space inside the equipment, which is divided into inner and outer chambers. The outer chamber is located at the front of the machine, and the inner chamber at the back. The peristaltic pump drive motor and its control board are fixed in the inner chamber, while the pump head and pump tubing are placed in the outer chamber. Removing the pump head requires disconnecting the pump head tubing from the internal tubing using specialized tools from the front of the equipment before replacing the pump head or tubing. If the internal motor or control board needs replacement, the equipment must be moved out and disassembled from the rear for replacement. This operation is extremely labor-intensive and time-consuming. Furthermore, for equipment with different channel requirements, the entire layout needs to be redesigned, resulting in poor versatility.

[0003] In view of the above-mentioned shortcomings, this utility model patent provides a modular peristaltic pump that can be quickly disassembled, independently tested and verified, and has a certain degree of versatility, as well as equipment using the modular peristaltic pump. Utility Model Content

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a modular peristaltic pump, comprising: a pump assembly body, a built-in peristaltic pump, and a control board; the pump assembly body forms a chamber inside, and the built-in peristaltic pump and the control board are assembled within the chamber; the built-in peristaltic pump has a flexible fluid conduit; the pump assembly body is provided with a first connector for liquid inlet, a second connector for liquid outlet, and a first power connector exposed on its outer surface; the first and second connectors are connected to the fluid conduit; the first power connector and the control board are electrically connected.

[0005] This technology integrates a built-in peristaltic pump and control board into a chamber on the outside of the pump unit, forming an independent modular peristaltic pump. This allows for easy installation of the modular peristaltic pump onto other equipment. The equipment is equipped with a third connector, a fourth connector, and a second power connector. After the modular peristaltic pump is installed on the equipment, the first and third connectors can be connected, the second and fourth connectors can be connected to complete the water circuit connection, and the first and second power connectors can be connected to complete the electrical circuit connection. The modular peristaltic pump can be quickly installed on the equipment, is simple and quick to operate, and can be quickly removed from the equipment as a whole.

[0006] As a preferred embodiment of this utility model, the pump assembly body includes: a middle shell, a front sealing plate detachably mounted on the front of the middle shell, and a rear sealing plate located on the back of the middle shell; the first connector, the second connector, and the first power connector are disposed on the rear sealing plate;

[0007] This technology allows the front cover plate to be detachably installed in the middle shell. When certain components of the built-in peristaltic pump, such as the built-in pump head assembly, are damaged and require repair or replacement, the entire modular peristaltic pump can be removed from the equipment, and the front cover plate can be removed for repair or replacement. Alternatively, the built-in pump head assembly can be repaired or replaced without removing the modular peristaltic pump, only by removing the front cover plate, making it more convenient to use. The first connector, the second connector, and the first power connector are located on the rear cover plate. When the modular peristaltic pump is pushed into the equipment, the rear cover plate is pushed into the installation cavity of the equipment first, enabling the first connector and the third connector, the second connector and the fourth connector, and the first power connector and the second power connector to be inserted into each other.

[0009] This technology specifically defines a locking method for the front cover plate and the middle shell. By rotating the handle, the locking block is moved inward and outward. When the locking block moves inward and leaves the lock hole, the front cover plate and the middle shell are unlocked, allowing the front cover plate to be removed for easy maintenance and replacement of parts. When the locking block moves outward and inserts into the lock hole, the front cover plate and the middle shell are locked.

[0010] In a preferred embodiment of this invention, the handle is rotatable to at least a first position and a second position, wherein...

[0011] In the first position, the locking block moves inward and disengages from the lock hole; the front cover and the middle shell are unlocked; in the second position, the locking block moves outward and inserts into the lock hole; the front cover and the middle shell are locked.

[0012] In a preferred embodiment of this utility model, the built-in peristaltic pump includes: a motor, a built-in pump housing, and a built-in pump head assembly.

The built-in pump head assembly corresponds to the front sealing plate. The motor is electrically connected to the control board.

[0013] This technology defines the specific structure of the built-in peristaltic pump. The built-in pump head assembly corresponds to the front cover plate. After removing the front cover plate, the built-in pump head assembly can be quickly repaired and replaced without removing the motor, which is simple and quick.

[0014] As a preferred embodiment of this utility model, a sensor is also installed inside the pump unit, and the sensor is electrically connected to the control board. In this technology, the sensor may include a temperature sensor and a pressure sensor. The temperature sensor can detect the temperature inside the cavity of the pump unit, especially the temperature near the motor, to prevent the motor from being damaged due to excessively high temperature during long-term operation. The pressure sensor detects the pressure of the pipe wall of the fluid pipeline to prevent blockage or leakage.

[0015] As a preferred embodiment of this utility model, the outer surface of the middle shell is provided with a guide block or guide groove to facilitate the installation of the modular peristaltic pump in the equipment.

[0016] The second aspect of this utility model provides a device having a housing and further comprising: the aforementioned modular peristaltic pump; the housing having a mounting cavity, the modular peristaltic pump being able to be placed into and removed from the mounting cavity; the housing being provided with a third connector, a fourth connector, and a second power connector;

[0017] After the modular peristaltic pump is installed in the mounting cavity, the third connector and the first connector are matched and connected; the fourth connector and the second connector are matched and connected; and the second power connector and the first power connector are matched and connected.

[0018] The equipment in this technology can quickly install and remove modular peristaltic pumps; when multiple modular peristaltic pumps are installed in the equipment, each modular peristaltic pump can be independently debugged, repaired, and replaced, making the modular peristaltic pump highly versatile.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Example 1:

[0036] Modular peristaltic pump, please refer to Figure 1-4 As shown, the system includes: a pump assembly body 100, a built-in peristaltic pump 200, and a control board 300; the pump assembly body 100 has an internal chamber, in which the built-in peristaltic pump 200 and the control board 300 are assembled; the built-in peristaltic pump 200 has a flexible fluid conduit; the pump assembly body 100 is provided with a first connector 101 for liquid inlet, a second connector 102 for liquid outlet, and a first power connector 103 exposed on its outer surface; the first connector 101 and the second connector 102 are connected to the fluid conduit; the first power connector 103 and the control board 300 are electrically connected, specifically, the first power connector 103 and the control board 300 can be connected by an electrical wire;

[0037] Specifically, such as Figure 1 As shown, the pump unit's outer casing 100 is a box-type structure. The built-in peristaltic pump 200 and control board 300 are installed within the chamber, allowing the entire modular peristaltic pump to be installed as a single, independent unit, enabling rapid installation into the equipment. Figure 5 As shown, multiple modular peristaltic pumps can be installed independently in the housing 400 of the equipment for independent testing and verification. If a modular peristaltic pump is damaged, it can be directly removed from the housing 400 for repair and replacement. The modular peristaltic pump has strong versatility.

[0038] The specific structure of the first connector 101 and the second connector 102 is not limited, as long as it can achieve pipeline connection. Optionally, the first connector 101 and the second connector 102 can be common quick connectors on the market.

[0039] Inside the cavity of the pump set body 100, the fluid pipe is connected to the first connector 101 and the second connector 102; the first connector 101 and the second connector 102 are exposed on the outer surface of the pump set body 100, so that the modular peristaltic pump can be connected to the interface of the equipment when it is installed in the equipment.

[0040] The specific structure of the first power connector 103 is not limited. The first power connector 103 may serve to conduct electricity or to provide both electricity and communication connection. Those skilled in the art can adapt the specific structure of the first power connector 103 according to actual needs.

[0041] The equipment is provided with a second power connector 413, and the first power connector 103 is exposed on the outer surface of the pump body 100, so that when the modular peristaltic pump is installed on the equipment, the first power connector 103 can be connected to the second power connector 413 of the equipment.

[0042] In one embodiment, the pump assembly body 100 includes: a middle shell 120, a front sealing plate 110 detachably mounted on the front of the middle shell 120, and a rear sealing plate 130 located on the back of the middle shell 120; a first connector 101, a second connector 102, and a first power connector 103 are disposed on the rear sealing plate 130.

[0043] Specifically, such as Figure 1-3 As shown, the middle shell 120 is hollow frame-shaped, the front sealing plate 110 is installed on the front of the middle shell 120, the rear sealing plate 130 is located on the back of the middle shell 120, and the entire pump set body 100 is rectangular.

[0044] Optionally, the shapes of the middle shell 120, the front sealing plate 110 and the rear sealing plate 130 can be changed so that the entire pump set body 100 is arranged in a columnar shape.

[0045] Furthermore, such as Figure 1-2 As shown, the rear cover 130 is divided into two parts, which together seal the back of the middle shell 120. The rear cover 130 includes a first plate 131 and a second plate 132. The first plate 131 is integrally formed with the middle shell 120, while the second plate 132 is separable from the middle shell 120. A first connector 101 and a second connector 102 are distributed on the first plate 131, and a first power connector 103 is distributed on the second plate 132.

[0046] When it is necessary to repair the motor or control board 300 of the built-in peristaltic pump 200, the second board 132 can be removed. Since the first connector 101 and the second connector 102 are distributed on the first board 131, the water circuit connection inside the modular peristaltic pump will not be affected when repairing the circuit part.

[0047] The second plate 132 can be fixed to the back of the middle shell 120 with screws or with clips. Since the first power connector 103 is installed on the second plate 132, when the modular peristaltic pump is installed on or removed from the equipment, the insertion or extraction force of the first power connector 103 is transmitted to the second plate 132 to prevent the second plate 132 from separating from the middle shell 120 during the installation or removal of the modular peristaltic pump. The second plate 132 is preferably fixed to the back of the middle shell 120 with screws.

[0048] The front cover plate 110 can also be installed on the middle shell 120 by means of a snap-on or locking mechanism, which can achieve the purpose of quick removal of the front cover plate 110. When maintenance is required, the front cover plate 110 can be removed.

[0049] Furthermore, the front cover plate 110 is provided with a pump unit locking assembly 140, which is used to lock or unlock the front cover plate 110 and the middle shell 120.

[0050] The pump unit locking assembly 140 includes: a rotatable handle 141 mounted on the front sealing plate 110 and a locking block 142 mounted on the front sealing plate 110. The locking block 142 is located on the inner side of the front sealing plate 110, and the handle 141 is located on the outer side of the front sealing plate 110, making it convenient for the user to apply force to rotate the handle 141. The handle 141 is connected to the locking block 142, and the handle 141 drives the locking block 142 to move. The middle shell 120 is provided with a locking hole 121 corresponding to the locking block 142.

[0051] Furthermore, the handle 141 can be rotated to at least a first position and a second position, wherein,

[0052] In the first position, the locking block 142 moves inward and disengages from the lock hole 121; the front cover plate 110 and the middle shell 120 are unlocked, and the front cover plate 110 can be removed from the middle shell 120.

[0053] In the second position, the locking block 142 moves outward and inserts into the lock hole 121, locking the front cover plate 110 and the middle shell 120, and the front cover plate 110 cannot be removed from the middle shell 120.

[0054] More specifically, the first structural configuration of the pump unit locking assembly 140 is: it also includes a turntable, on which an arc-shaped groove is provided extending from the center to the outer edge;

[0055] The handle 141 is connected to the center of the turntable, and the turntable rotates when the handle 141 rotates.

[0056] There are two locking blocks 142, one of which is located above the left side of the front sealing plate 110 and the other is located below the right side of the front sealing plate 110. Each locking block 142 has a pin at its end, which passes through the arc groove and can move along the arc groove.

[0057] The inner side of the front cover plate 110 is also provided with a limiting sleeve or limiting groove that limits the linear inward and outward movement of the locking block 142. When the handle 141 is rotated in the forward direction, it pushes the pin from the beginning to the end of the arc groove, pushing the locking block 142 outward to insert into the lock hole 121; when the handle 141 is rotated in the reverse direction, it pushes the pin from the end to the beginning of the arc groove, causing the locking block 142 to move inward away from the lock hole 121.

[0058] Here, the end of the arc groove closest to the center of the turntable is the beginning, and the end furthest from the center of the turntable is the end; optionally, the number of locking blocks 142 can be adapted, and the number of arc grooves can also be adapted.

[0059] Of course, the handle 141 can also be rotated to other positions.

[0060] Optionally, the second structural configuration of the pump unit locking assembly 140 further includes: a first connecting rod and a second connecting rod; two locking blocks 142 are provided, one located above the left side of the front sealing plate 110 and the other located below the right side of the front sealing plate 110, each locking block 142 having a pin at its end, and each locking block 142 being connected to the handle 141 via the first connecting rod and the second connecting rod respectively; specifically, the first end of the first connecting rod is connected to the handle 141, the second end is connected to the first end of the second connecting rod, and the second end of the second connecting rod is connected to the locking block 142; a straight groove is provided on the inner side of the front sealing plate 110, and the locking block 142 is installed in the straight groove, limiting the locking block 142 to only move in a straight line to achieve inward and outward movement; rotating the handle 141 can drive the locking block 142 to move inward and outward along the straight groove.

[0061] In one embodiment, the built-in peristaltic pump 200 includes: a motor 210, a built-in pump housing 220, and a built-in pump head assembly 230. The built-in pump housing 220 is located on the front of the motor 210, and the built-in pump head assembly 230 is mounted on the front of the built-in pump housing 220. The built-in pump head assembly 230 corresponds to the front cover plate 110, allowing for easy replacement or repair of the built-in pump head assembly 230 after removing the front cover plate 110. The motor 210 is electrically connected to the control board 300, specifically, the motor 210 and the control board 300 are connected via wires. The built-in pump head assembly 230 and the built-in pump housing 220 are fixed together with screws.

[0062] A fluid pipe is provided in the cavity of the pump unit body 100. The first end of the fluid pipe is connected to the first connector 101 and the second end is connected to the second connector 102. Fluid flows into the fluid pipe from the first connector 101. The built-in pump head assembly 230 should include at least a roller. The roller acts on a certain section of the fluid pipe to push a certain amount of fluid out from the second connector 102.

[0063] In one embodiment, a sensor 150 is also installed inside the pump assembly body 100, and the sensor 150 is electrically connected to the control board 300.

[0064] Sensor 150 includes: a temperature sensor and a pressure sensor;

[0065] The temperature sensor is installed inside the pump unit body 100 near the motor 210 to better sense the temperature near the motor 210, and then determine whether the motor 210 is overheating, preventing the motor 210 from overheating due to prolonged use of the modular peristaltic pump; when applied to equipment, the signal of the temperature sensor can be transmitted to the equipment's control system, and then notify the user that the modular peristaltic pump is overheating and needs to be stopped or cooled down.

[0066] Pressure sensors detect the pressure on the walls of fluid pipelines to prevent blockages or leaks. When applied to equipment, temperature sensors can transmit signals to the equipment's control system, thereby notifying the user of any pipeline blockages or leaks that should be repaired promptly.

[0067] Furthermore, the outer surface of the middle shell 120 is provided with guide blocks or guide grooves, such as... Figure 2 As shown, guide blocks 122 are provided on the upper and lower surfaces of the middle shell 120. The guide blocks 122 are strip-shaped and extend from the front to the back of the middle shell 120. The diameter of the guide blocks 122 gradually decreases near the back, which facilitates the installation of the modular peristaltic pump in the equipment.

[0068] Optionally, the number of guide blocks 122 can be changed.

[0069] A guide groove 414 should be provided in the mounting cavity 410 of the equipment corresponding to the guide block 122.

[0070] Example 2:

[0071] A device, such as Figure 5-6 As shown, the device has a housing 400 and a modular peristaltic pump as in Embodiment 1; the housing 400 has multiple mounting cavities 410, the modular peristaltic pump can be placed into the mounting cavity 410 and removed from the mounting cavity 410, and the multiple modular peristaltic pumps are independently installed in the mounting cavity 410, and can be independently tested, verified and operated after installation;

[0072] The housing 400 is provided with a third connector 411, a fourth connector 412, and a second power connector 413; after the modular peristaltic pump is installed in the mounting cavity 410, the third connector 411 and the first connector 101 are matched and connected; the fourth connector 412 and the second connector 102 are matched and connected; and the second power connector 413 and the first power connector 103 are matched and connected.

[0073] The specific structures of the third connector 411 and the fourth connector 412 are set according to the specific structures of the first connector 101 and the second connector 102.

[0074] The specific structure of the second power connector 413 is set according to the specific structure of the first power connector 103. It can be understood that if the first power connector 103 is a conductive male terminal, then the second power connector 413 is a conductive female terminal.

[0075] When in use, simply push the modular peristaltic pump into the mounting cavity 410; when not in use, simply pull the modular peristaltic pump out of the mounting cavity 410.

[0076] During installation, the rear sealing plate 130 of the modular peristaltic pump first enters the installation cavity 410. During the process of pushing the modular peristaltic pump into the installation cavity 410, the third connector 411 and the first connector 101 are connected; the fourth connector 412 and the second connector 102 are connected; and the second power connector 413 and the first power connector 103 are connected.

[0077] The third connector 411 and the fourth connector 412 are connected to other external pipes accordingly, and the second energized connector 413 is connected to external power accordingly.

[0078] Furthermore, the inner wall of the mounting cavity 410 is provided with a locking groove 401; the locking groove 401 cooperates with the locking block 142 provided on the outer body 100 of the pump unit; the handle 141 provided on the outer body 100 of the pump unit can be rotated to a third position, wherein, when the handle 141 is in the third position, the locking block 142 moves outward to be inserted into the locking groove 401; the modular peristaltic pump is locked to the housing 400;

[0079] Specifically, such as Figure 4 As shown, the third position is when the handle 141 is rotated to the horizontal position; the first position is when the handle 141 is rotated to the vertical position; the second position is when the handle 141 is rotated to a position that tilts from the upper left to the lower right. Figure 4 The dotted line section is a schematic diagram showing the handle rotated to the first and second positions.

[0080] During installation, first rotate the handle 141 to the second position, locking the front cover plate 110 and the middle shell 120. After pushing the modular peristaltic pump into the installation cavity, rotate the handle 141 to the third position, locking the modular peristaltic pump and the shell 400.

[0081] When the built-in pump head assembly needs to be repaired, simply rotate the handle 141 to the first position and remove the front cover plate 110.

[0082] More specifically, the pump unit locking assembly 140 adopts the first structural method. When the handle 141 is rotated to the first position and the handle 141 is vertical, the pin of the locking block 142 is located at the beginning of the arc groove. The locking block 142 leaves the locking groove 401 and the locking hole 121. The front sealing plate 110 can be pulled outward through the handle 141.

[0083] Rotate the handle 141 forward to the second position. The pin moves along the arc groove towards the end of the arc groove. When it moves to about halfway, the handle 141 rotates to the second position. The locking block 142 moves outward and inserts into the locking hole 121, locking the front cover plate 110 and the middle shell 120. The entire modular peristaltic pump can be pushed into or pulled out of the equipment.

[0084] After the modular peristaltic pump is installed on the equipment, the handle 141 continues to rotate forward to the third position, the pin moves to the end of the arc groove, and the locking block 142 continues to move outward and insert into the locking groove 401, thus limiting the modular peristaltic pump and the housing 400.

[0085] Furthermore, the inner wall of the mounting cavity 410 is provided with a guide groove or guide block for guiding the installation of the modular peristaltic pump. Specifically, the upper and lower surfaces of the shell 120 in Embodiment 1 are provided with guide blocks 122, and the inner wall of the mounting cavity 410 is provided with a guide groove 414.

[0086] Optionally, the upper and lower surfaces of the middle shell 120 may be provided with guide grooves, and the inner wall of the mounting cavity 410 may be provided with guide blocks.

[0087] Furthermore, the device in this embodiment can be applied to beverage machines.

[0088] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
