Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, and in particular to a device for preventing peristaltic pump leakage from damaging the motor. Background Technology

[0002] Current peristaltic pumps work by using a motor to drive a squeezing wheel, which squeezes the pipes inside the pump, forcing the liquid out of the outlet. After a period of use, the continuous squeezing of the pipes can cause them to break. When the pipes break, the liquid inside will flow towards the motor's main shaft and into the motor, damaging it and reducing its lifespan. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device to prevent leakage of peristaltic pump from damaging the motor, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A device for preventing leakage from a peristaltic pump from damaging the motor includes a motor, a peristaltic pump, a first gear, a second gear, and a fixed base; the motor is fixedly connected to the fixed base, the second gear is rotatably connected to the fixed base, the fixed base is provided with a liquid collection tank, the main shaft of the motor is connected to the first gear, the second gear is fixedly connected to the central shaft of the peristaltic pump, the second gear and the first gear mesh with each other, the liquid collection tank is located on one side of the second gear and away from the first gear, and the main shaft of the motor and the peristaltic pump are offset from each other.

[0006] A preferred embodiment of the device for preventing leakage from the peristaltic pump from damaging the motor further includes a fixing block, which is positioned directly above the fixing base. The upper surface of the fixing block has a first fixing groove, in which the fixing plate of the peristaltic pump is fixed. The lower surface of the fixing block has a second fixing groove, in which an upper bearing is installed. The upper surface of the fixing base has a third fixing groove, in which a lower bearing is installed. The center of the second gear has a fixing shaft, the lower end of which is rotatably connected to the lower bearing, and the upper end of which passes through the upper bearing and is connected to the central shaft of the peristaltic pump.

[0007] A preferred embodiment is that the third fixing tank is connected to the liquid collection tank.

[0008] In a preferred embodiment, the fixed stop is fixedly connected to the fixed seat via a support column, and an installation space is formed between the fixed stop and the fixed seat.

[0009] A preferred embodiment is that the bottom of the liquid collection tank is provided with a liquid outlet.

[0010] The device for preventing motor damage from peristaltic pump leakage provided in this embodiment of the invention has at least the following beneficial effects: The peristaltic pump has a pipe inside, with one end as the inlet and the other end as the outlet. When the motor is working, the motor drives the first gear to rotate, the first gear drives the second gear to rotate, the second gear drives the central shaft of the peristaltic pump to rotate, and the central shaft of the peristaltic pump drives the squeezing wheel of the peristaltic pump to rotate. The liquid in the pipe flows out from the outlet after being squeezed by the squeezing wheel. When the pipe is damaged, the liquid in the pipe will flow out of the peristaltic pump and then flow to the second gear or the collection tank. The liquid on the second gear eventually flows to the collection tank. Because the motor shaft and the peristaltic pump are offset from each other, it prevents the liquid in the pipe from flowing to the motor shaft, thus improving the service life of the motor. When a certain amount of liquid is collected in the collection tank, it can be poured out.

[0011] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0016] To illustrate the ideas and objectives of this application, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," "left," "right," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] like Figures 1 to 4 As shown, a device for preventing leakage from a peristaltic pump 20 that could damage a motor 10 includes a motor 10, a peristaltic pump 20, a first gear 30, a second gear 40, and a fixed base 50. The motor 10 is fixedly connected to the fixed base 50, and the second gear 40 is rotatably connected to the fixed base 50. The fixed base 50 is provided with a liquid collection tank 51. The main shaft of the motor 10 is connected to the first gear 30, and the second gear 40 is fixedly connected to the central shaft 24 of the peristaltic pump 20. The second gear 40 and the first gear 30 mesh with each other. The liquid collection tank 51 is located on one side of the second gear 40 and away from the first gear 30. The main shaft of the motor 10 and the peristaltic pump 20 are offset from each other.

[0020] like Figures 1 to 4 As shown, the peristaltic pump 20 has a pipe inside, with one end being the inlet 21 and the other end being the outlet 22. When the motor 10 is working, the motor 10 drives the first gear 30 to rotate, which in turn drives the second gear 40 to rotate. The second gear 40 drives the central shaft 24 of the peristaltic pump 20 to rotate, which in turn drives the squeezing wheel of the peristaltic pump 20 to rotate. The liquid in the pipe is squeezed by the squeezing wheel and flows out from the outlet 22. When the pipe is damaged, the liquid in the pipe will flow out of the peristaltic pump 20 and then flow to the second gear 40 or the collection tank 51. The liquid on the second gear 40 eventually flows to the collection tank 51. Because the main shaft of the motor 10 and the peristaltic pump 20 are offset from each other, it prevents the liquid in the pipe from flowing to the main shaft of the motor 10, thus improving the service life of the motor 10. When a certain amount of liquid is collected in the collection tank 51, it can be poured out.

[0021] like Figures 1 to 4As shown, the device for preventing leakage of the peristaltic pump 20 from damaging the motor 10 also includes a fixing block 60. The fixing block 60 is located directly above the fixing base 50. The upper surface of the fixing block 60 is provided with a first fixing groove 61. The fixing plate 23 of the peristaltic pump 20 is fixed in the first fixing groove 61. The lower surface of the fixing block 60 is provided with a second fixing groove 62. The second fixing groove 62 is provided with an upper bearing 63. The upper surface of the fixing base 50 is provided with a third fixing groove 52. The third fixing groove 52 is provided with a lower bearing 53. The center of the second gear 40 is provided with a fixing shaft 41. The lower end of the fixing shaft 41 is rotatably connected to the lower bearing 53. The upper end of the fixing shaft 41 passes through the upper bearing 63 and is connected to the central shaft 24 of the peristaltic pump 20.

[0022] like Figures 1 to 4 As shown, when the pipe is damaged, the liquid inside the pipe will flow out of the peristaltic pump 20 and then flow to the second gear 40 or the liquid collection tank 51. The liquid on the second gear 40 will eventually flow to the liquid collection tank 51. The fixed stop 60 is set directly above the fixed base 50, which plays a certain role in isolation and further prevents the liquid in the pipe from flowing to the main shaft of the motor 10, thereby improving the service life of the motor 10.

[0023] like Figures 1 to 4 As shown, the third fixing tank 52 is connected to the liquid collection tank 51.

[0024] like Figures 1 to 4 As shown, when the pipe is damaged, the liquid inside will flow out of the peristaltic pump 20, and then flow to the second gear 40 or the collection tank 51. The liquid on the second gear 40 flows to the third fixed tank 52, which is connected to the collection tank 51. The liquid in the third fixed tank 52 eventually flows to the collection tank 51. This prevents the liquid in the pipe from flowing to the main shaft of the motor 10, thus improving the service life of the motor 10.

[0025] like Figures 1 to 4 As shown, the fixed stop 60 is fixedly connected to the fixed base 50 through the support column 70, and an installation space is formed between the fixed stop and the fixed base 50.

[0026] like Figures 1 to 4 As shown, the bottom of the liquid collection tank 51 is provided with a liquid outlet 511. When a certain amount of liquid is collected in the liquid collection tank 51, it can flow out from the liquid outlet 511.

[0027] The above are specific embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
