A peristaltic pump generally consists of three parts: the driver, the pump head, and the hose. The fluid is isolated in the hose. The peristaltic pump is like a hose filled with fluid clamped with your fingers. As the fingers slide forward, the hose is The fluid is driven to move forward.

How to pump out the care products and realize the recovery of care products, the peristaltic pump is a better choice, but the current user demand for the care device is that the volume needs to be small, but the existing peristaltic pumps are all large in size, and the peristaltic pump The use of the pump in the nursing device can easily cause the size of the nursing device to be too large, causing inconvenience to use. Therefore, it is necessary to consider providing a peristaltic pump capable of miniaturizing the care device.

Based on the above requirements, the peristaltic pump of the embodiment of the present application is proposed.

As shown in Figures 1 to 4, an embodiment of the present application provides a peristaltic pump 54 that includes a housing 10, a motor 20, and a first conduit 40.

The size of the peristaltic pump 54 is small. When applied to the nursing device 50, it can Effectively control the size of the nursing device. Specifically, the suction or discharge of liquid is achieved by controlling the rotation direction of the rotating shaft 21 of the motor 20. One end of the first pipe 40 extends into the outer container 53, the motor 20 works to make the rotating shaft 21 rotate, and the rotating shaft 21 drives the eccentric 30 to rotate and squeeze the first pipe 40 outside the eccentric 30.

The gearbox 23 is arranged on the side of the body 22 close to the rotating shaft 21. The size of the gearbox 23 is larger than the size of the plug hole 121. The gearbox 23 is clamped in the container. It is placed in the cavity 11, and the body 22 extends from the casing. By arranging the gearbox 23 on the motor 20, the gearbox 23 can be clamped and fixed with the first housing 12, and the end of the motor 20 away from the gearbox 23 can pass through the insertion hole 121 to realize the rotation of the motor 20 The shaft 21 is stably fixed in the housing 10, and the end of the motor 20 away from the gearbox 23 protrudes from the insertion hole 121, which is convenient for fixing the motor 20 in the housing 10 firmly.

Further, in this embodiment, the eccentric 30 is connected to the slot of the rotating shaft 21. Since the fixing method of the slot connection is simple and the connection method is relatively stable, the slot connection of the eccentric wheel 30 and the rotating shaft 21 can effectively ensure the assembly efficiency and the stability of the peristaltic pump 54.

Specifically, in this embodiment, the connection mode of the eccentric 30 and the rotating shaft 21 may also be any one of keyway connection, snap-fit connection, chuck connection, slot connection, pin connection or threaded connection. The connection mode of the eccentric wheel 30 and the rotating shaft 21 is not uniquely limited here. Taking the meshing connection as an example, the end of the rotating shaft 21 is provided with teeth, and the eccentric wheel 30 is meshed and connected with the rotating shaft 21. Specifically, the eccentric wheel 30 is provided with an eccentric hole, and the inner wall of the eccentric hole is provided with an engaging structure corresponding to the tooth, so that the eccentric wheel 30 and the rotating shaft 21 can be meshed and connected with the tooth through the engaging structure.

Example two

Based on the above requirements, how to pump out the care products drop by drop and realize the recovery of the care products? Peristaltic pumps are a better choice. However, the existing portable peristaltic pumps are relatively small in size, but the existing peristaltic pumps are all in size. If the peristaltic pump is used in the nursing device, the size of the nursing device is too large, which can cause inconvenience to use. Therefore, it is necessary to consider how to design and install a peristaltic pump.

As shown in Figures 1-7, the embodiment of the present application also provides a nursing device 50, which includes a mounting shell 51, a control device 52, a container 53, and a peristaltic pump 54. The peristaltic pump 54 and the control device 52 are all arranged in the mounting shell 51 The peristaltic pump 54 and the control device 52 are both arranged in the mounting shell 51. One end of the first tube 40 of the peristaltic pump 54 is connected to the container 53, and the other end of the first tube 40 extends outside the mounting shell 51. The container 53 is used for Store care products. The peristaltic pump 54 includes a housing 10, a motor 20, and a first duct 40. The housing 10 is provided with a duct opening 26, the housing 10 is provided with an annular abutment portion extending inward, and the rotating shaft 21 of the motor 20 is inserted into the housing 10. An eccentric wheel 30 is fixed on the rotating shaft 21, a groove 25 is formed between the abutting portion and the eccentric wheel 30, the first pipe 40 is embedded in the groove 25, and both ends of the first pipe 40 extend to the pipe opening 26. 40 is a flexible tube, and the eccentric wheel 30 rotates with the rotation shaft 21 to press the first pipe 40 against the abutting portion so that the first pipe 40 can transport liquid.

The care device 50 of the embodiment of the present application is provided with a container 53 and a peristaltic pump 54. The container 53 stores care products that increase fragrance or lubrication, such as essential oils. The peristaltic pump 54 removes the care products from the container 53 through the first conduit 40. Pump out, and then transport to the outside of the mounting shell 51. Through the control device 51, the work of the rotating shaft 21 can be controlled in real time, so that the care instrument can output the care products/nursing solution regularly and quantitatively. The user can adjust the care solution in real time according to specific needs. The amount of liquid.

Of course, the nursing device 50 of the embodiment of the present application can also adopt the peristaltic pump 54 of the first embodiment, and the technical features of the peristaltic pump 54 can all be introduced into the second embodiment.

Further, in another embodiment, a second pipe (not shown in the figure) is further provided in the housing 10, one end of the second pipe extends to the surface of the housing 10, and the other end extends into the container 53. By arranging a second pipe, one end of the second pipe can be synchronously connected with the external container 53. The second pipe can simultaneously replenish gas into the container 53 or from the container 53 when the first pipe 40 is squeezed by the eccentric 30. The gas is output outside, so that the air pressure in the outer container 53 is balanced.

In another embodiment, the second duct is spaced apart from the eccentric 30. In addition, the second tube and the eccentric wheel 30 are spaced apart, that is, the second tube does not contact the eccentric wheel, and the first tube 40 and the second tube will not interfere with each other. Furthermore, a pressure balance device is provided at one end of the second conduit away from the container 53.

In this way, on the one hand, when the care device 50 is working normally, the peristaltic pump 54 draws out the care products in the container 53, and the pressure balance device inflates the container 53, so that the air pressure in the container 53 is balanced; on the other hand, the care device 50 stops working Later, in order to prevent care products from remaining in the first catheter 40, the control device 52 can control the peristaltic pump 54 to work in reverse so that the care products in the first catheter 40 can flow back into the container 53, in order to maintain the balance of the air pressure in the container 53, The air in the container 53 will be discharged through the second duct, but since the care device 50 is placed at a random angle after use, when the second duct discharges air, the care products will be discharged from the second duct at the same time. The pressure balance device can prevent care products from being discharged from the second conduit, thereby preventing liquid leakage and waste of care products.

In another embodiment, the second conduit may not be provided, but a one-way valve 58 is provided on the cap of the container 53.
