Description

Technical Field

[0001] This utility model relates to the field of pump technology, and in particular to a blood pressure monitor valve integrated pump. Background Technology

[0002] In existing technology, electronic blood pressure monitors typically use an inflation pump and a solenoid valve to inflate and deflate the cuff or wristband. However, this design has some drawbacks:

[0003] 1. Size and cost issues: The air pump and solenoid valve are relatively large, which increases the overall size and manufacturing cost of the blood pressure monitor;

[0004] 2. Reliability issues: The adhesive on the valve core of the solenoid valve is prone to falling off, which affects the performance and safety of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide an integrated pump for a blood pressure monitor with an integrated valve.

[0006] To achieve the above objectives, the following technical solution is adopted:

[0007] A sphygmomanometer valve integrated pump includes a motor, the output shaft of which is connected to an output wheel. The output wheel is eccentrically connected to an output frame. The output frame is provided with multiple impact parts, which are connected to a movable cylinder. The movable cylinder is elastic and has one or more first cavities. The movable cylinder causes the first cavities to expand or contract under the eccentric movement of the impact parts. A liner is provided on the movable cylinder. The liner is provided with multiple output holes and mounting holes respectively connected to different first cavities. An umbrella-shaped valve plate is inserted into the mounting hole, and the valve plate covers the corresponding output hole. A venting groove is also provided on the side of the liner facing the movable cylinder. A first input hole is provided on one side of the first cavity of the movable cylinder. An elastic baffle is provided in the first input hole. When the movable cylinder is in contact with the liner, the venting groove connects the first cavity and the first input hole.

[0008] It also includes a fixing bracket, which is used to make the movable cylinder fit against the underside of the pad. The fixing bracket is provided with a second input hole corresponding to the first input hole. Under normal conditions, the elastic baffle blocks the second input hole.

[0009] It also includes a top cover, one side of which is provided with an output nozzle, and the other side is provided with a second cavity for the movement of the umbrella-shaped valve plate, the second cavity being connected to the output nozzle.

[0010] Furthermore, the output frame includes an output rod and a plurality of impact parts rotatably connected to one end of the output rod. The output rod is eccentrically connected to the output wheel, and a connecting rod is provided on the outer surface of the first cavity of the movable cylinder. The impact parts are limited and connected to the connecting rod. When the output wheel is driven to rotate by the motor, one end of the output rod of the output frame revolves, and its other end is rotatably connected to the impact parts. Therefore, the output rod forms a pressing cycle, that is, it alternately presses down on each impact part, which can drive the movable cylinder to move alternately. Specifically, a connecting part is formed at the midpoint of the plurality of impact parts, and one end of the output rod is rotatably limited within the connecting part.

[0011] Furthermore, the integrated pump also includes a support frame, which is mounted in the fixed frame and serves to provide support for the midpoints of the plurality of impact parts, thus providing a fulcrum for the movement of the impact parts.

[0012] Furthermore, the support frame is located between the movable cylinder and the fixed frame, a sealing plug is inserted into the center of the support frame, and the fixed frame has an insertion hole that mates with the sealing plug at its center.

[0013] Furthermore, the first cavity has three parts.

[0014] Furthermore, the integrated pump also includes a housing, which is disposed between the mounting bracket and the motor.

[0015] Furthermore, the padding, the fixing bracket, and the housing are fixed to the motor after being passed through by the same bolt.

[0016] By adopting the above solution, the beneficial effects of this utility model are:

[0017] The output frame and the movable cylinder are driven by the eccentric movement of a motor, which allows the movable cylinder to draw in and output gas. The overall structure is compact and small in size, which can effectively reduce manufacturing costs. Attached Figure Description

[0027] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0028] like Figure 1-7 As shown, a sphygmomanometer valve integrated pump includes a motor 1, the output shaft of the motor 1 is connected to an output wheel 2, the output wheel 2 is eccentrically connected to an output frame 3, the output frame 3 is provided with multiple impact parts 31, the impact parts 31 are connected to a movable cylinder 4, the movable cylinder 4 is elastic and has one or more first cavities 41, the movable cylinder 4 is driven by the eccentric movement of the impact parts 31 to cause the first cavities 41 to expand or contract, a pad 5 is provided on the movable cylinder 4, the pad 5 is provided with multiple output holes 51 and mounting holes 52 respectively connected to different first cavities 41, an umbrella-shaped valve plate 6 is inserted into the mounting hole 52, the valve plate covers the corresponding output hole 51, the side of the pad 5 facing the movable cylinder 4 is also provided with a venting groove 53, a first input hole 42 is provided on one side of the first cavity 41 of the movable cylinder 4, an elastic baffle 43 is provided in the first input hole 42, when the movable cylinder 4 is in contact with the pad 5, the venting groove 53 connects the first cavity 41 and the first input hole 42;

[0029] It also includes a fixing frame 7, which is used to make the movable cylinder 4 fit under the pad 5. The fixing frame 7 is provided with a second input hole 71 corresponding to the first input hole 42. Under normal conditions, the elastic baffle 43 blocks the second input hole 71.

[0030] It also includes a top cover 8, one side of which is provided with an output nozzle 81, and the other side is provided with a second cavity 82 for the movement of the umbrella-shaped valve plate 6, the second cavity 82 being connected to the output nozzle 81.

[0031] The output frame 3 includes an output rod 32 and multiple impact parts 31 rotatably connected to one end of the output rod 32. The output rod 32 is eccentrically connected to the output wheel 2. A connecting rod 44 is provided on the outer surface of the first cavity 41 of the movable cylinder 4, and the impact parts 31 are limited and connected to the connecting rod 44. When the output wheel 2 is driven to rotate by the motor 1, one end of the output rod 32 of the output frame 3 revolves, and its other end is rotatably connected to the impact parts 31. Therefore, the output rod 32 forms a pressing cycle, that is, it alternately presses down on each impact part 31, which can drive the movable cylinder 4 to move alternately. Specifically, a connecting part 33 is formed at the midpoint of the multiple impact parts 31, and one end of the output rod 32 is rotatably limited within the connecting part 33.

[0032] The integrated pump also includes a support frame 9, which is mounted in the fixed frame 7 and provides support for the midpoint of the multiple impact parts 31. That is, it provides a fulcrum for the movement of the impact parts 31. The support frame 9 is located between the movable cylinder 4 and the fixed frame 7, and a sealing plug 91 is inserted into the center of the support frame 9. The fixed frame 7 has a socket 72 at its center that mates with the sealing plug 91.

[0033] The first cavity 41 has three parts.

[0034] The integrated pump also includes a housing 10, which is disposed between the mounting bracket 7 and the motor 1.

[0035] After the padding 5, the fixing bracket 7, and the housing 10 are passed through by the same bolt 11, they are fixed to the motor 1.

[0036] Explanation of the principle:

[0037] When motor 1 rotates, output wheel 2 is driven to rotate by motor 1, causing one end of output rod 32 of output frame 3 to revolve. Since its other end is rotatably connected to impact part 31, output rod 32 will form a pressing cycle, that is, it will alternately press down each impact part 31, which can drive the movable cylinder 4 to move in turn. Specifically, a connecting part 33 is formed at the midpoint of the multiple impact parts 31, and one end of output rod 32 is rotatably limited within the connecting part 33.

[0038] When the first chamber 41 of the movable cylinder 4 expands, the umbrella-shaped valve 6 on the output port 51 blocks gas from entering through it. Since the vent 53 connects the first chamber 41, the first input port 42, and the second input port 71, gas flows in through the second input port 71, pushing open the elastic baffle 43 on the first input port 42 and entering the first chamber 41. When the first chamber 41 contracts, the elastic baffle 43 blocks the second input port 71, allowing gas to pass only through the output port 51, pushing open the umbrella-shaped valve 6, converging in the second chamber 82 and the output nozzle 81, and then being ejected to inflate the sphygmomanometer's strap.

[0039] Beneficial effects:

[0040] The output frame 3 and the movable cylinder 4 are driven by the eccentric movement of a motor 1, so that the movable cylinder 4 can extract and output gas. The overall structure is compact and small in size, which can effectively reduce manufacturing costs.

[0041] Although this disclosure has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Because this disclosure can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
