Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a magnetic ring seat assembly and a pump device. Background Technology

[0002] Most existing medical pumps are centrifugal pumps, which generally consist of a pump motor and a pump head. Blood flow is achieved by the centrifugal pump motor driving the rotation of the pump head. Mature centrifugal medical pumps currently available in the domestic market can generally be divided into "single-point pumps" and "dual-point pumps" based on pump head type. "Single-point pumps" and "dual-point pumps" refer to single-pivot centrifugal blood pumps and dual-pivot centrifugal blood pumps, respectively. The main difference lies in the fulcrum supporting the centrifugal impeller within the pump head and its magnetic coupling. Due to this difference in magnetic coupling, the pump head and pump motor are not interchangeable. The pump heads and pump motors of "single-point pumps" and "dual-point pumps" are incompatible. Therefore, depending on the usage environment and needs, users need to replace different pump motors to assemble "single-point pumps" and "dual-point pumps" to meet the needs of different emergency situations. The wide variety of pump heads and pump motors, lacking compatibility and interchangeability, increases material and product management costs. The diverse product development not only reduces product convenience but also increases development and material costs.

[0003] Therefore, it is necessary to provide a novel magnetic ring seat assembly and pump device to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0033] The main advantages of the magnetic ring seat assembly and pump device described in this application are as follows:

[0034] The magnetic ring seat assembly integrates and fixes the first magnet and the second magnet on the same magnetic ring seat, so that a number of the first magnets form a first magnetic ring and a number of the second magnets form a second magnetic ring, which respectively cooperate with the iron ring to form the first ring component and the second ring component. The magnetic fields of the two types of magnetic rings do not interfere with each other, and can be used with single-point pump heads and double-point pump heads respectively to assemble "single-point pumps" and "double-point pumps". This solves the problems of incompatibility between pump heads and pump machines of "single-point pumps" and "double-point pumps", which are numerous, non-interchangeable, increase the management cost of materials and products, reduce the convenience of products, and increase development and material costs.

[0035] The pump unit not only allows for the matching of single-point and dual-point pump heads on a single pump, but also enables seamless switching between electric and manual modes in emergency situations. This eliminates the need for manual disassembly and installation of the pump, saving time and reducing the risk of errors during rescue operations. Furthermore, the integration of two drive mechanisms reduces redundant components and lightens the overall weight of the transmission and medical pump. This pump unit integrates a single-point pump, a dual-point pump, an electric pump, and a hand-cranked pump into a single, four-in-one medical centrifugal pump. This optimizes the existing structure of medical centrifugal pumps, saves costs, simplifies product variety, increases functionality and portability, and only increases size and weight by about 10%. This reduces the burden on medical personnel during outdoor emergency rescues and the associated material management costs, while also lowering the risk of errors during replacement.

[0048] Figure 1 This is a schematic diagram of the pump device according to an embodiment of this application; Figure 2 for Figure 1 The diagram shown is an exploded view of the pump unit.

[0049] To overcome the problems existing in the prior art, embodiments of this application provide a magnetic ring seat assembly and a pump device. (Reference) Figure 1 and Figure 2 The pump device includes a pump motor 10, a magnetic ring seat assembly 20, a pump motor cover assembly 30, and a pump head 40. One end of the magnetic ring seat assembly 20 is connected to the pump head 40 via the pump motor cover assembly 30, and the other end of the magnetic ring seat assembly 20 is connected to the pump motor 10. The pump device is operated by the pump motor 10 driving the magnetic ring seat assembly 20 to rotate. The magnetic ring seat assembly 20 and the pump head 40 form a magnetic coupling, thereby driving the impeller in the pump head 40 to rotate under the action of the magnetic moment.

[0050] In some embodiments of this application, the pump 10 includes a pump base assembly 11, a display module 12, a pump base 13, a pump base top cover 14, and a foldable handle 15. The display module 12 is disposed on the outer wall of the pump housing (not shown in the figure) of the pump base assembly 11. The pump base 13 is fixedly disposed on the bottom of the pump base assembly 11, and the pump base top cover 14 is fixedly disposed on the top of the pump base assembly 11. The pump base 13 and the pump housing (not shown in the figure) are provided with a communicating receiving portion 16, and the foldable handle 15 is folded and received in the receiving portion 16 (e.g., ...).

[0053] In some embodiments of this application, the pump base cover 14 serves to position, seal, and facilitate installation. The structure of the pump base cover 14 is common knowledge in the art and will not be described in detail here.

[0054] In some embodiments of this application, the pump cover assembly 30 is used to support and lock the pump head 40 and seal the pump 10. Specifically, the structure of the pump cover assembly 30 is common knowledge in the art and will not be described in detail here.

[0055] Figure 3 for Figure 1 The diagram shows the structure of the magnetic ring seat assembly in the pump device. Figure 4 for Figure 3 A top view of the magnetic ring seat assembly shown; Figure 5 for Figure 3 The magnetic ring seat assembly shown is a cross-sectional view along line A-A1.

[0056] In some embodiments of this application, reference is made to Figures 3 to 5 The magnetic ring assembly includes a magnetic ring seat 21, a first magnet 22 (e.g., a magnet used in a single-point pump), a second magnet 23 (e.g., a magnet used in a two-point pump), and an iron ring 24. A plurality of first magnets 22 are provided, and the plurality of first magnets 22 are disposed on the magnetic ring seat 21 and arranged to form a first magnetic ring 221 (e.g., a magnet used in a two-point pump). Figure 4 (As shown). A plurality of second magnets 23 are provided, and the plurality of second magnets 23 are disposed on the magnetic ring seat 21 and surround to form a second magnetic ring 231 (as shown). Figure 4 (As shown). The iron ring 24 is disposed on the magnetic ring seat 21, and the iron ring 24 and the first magnetic ring 221 form a first annular component (e.g., a single-point magnetic ring for a single-point pump), and the iron ring 24 and the second magnetic ring 231 form a second annular component (e.g., a dual-point magnetic ring for a dual-point pump). The iron ring 24 is used in conjunction with the first magnetic ring 221 or the second magnetic ring 231 to strengthen the magnetic field strength in a specific direction.

[0057] In some embodiments of this application, the iron ring is a pure iron ring, which is electrical pure iron, currently the material with the highest magnetic permeability. Electrical pure iron, also known as industrial pure iron, is a high-quality steel with an iron content of over 99.5%, and is a low-carbon, low-sulfur, and low-phosphorus iron.

[0058] In some embodiments of this application, the first magnet 22 and the second magnet 23 are fixedly disposed on the magnetic ring seat 21 by adhesive, and the iron ring 24 is fixedly disposed on the magnetic ring seat 21 by adhesive or screw.

[0059] In some embodiments of this application, reference is made to Figures 3 to 5 The magnetic ring seat 21 is generally groove-shaped and includes a mounting wall 211, a base 212, and a rotating shaft connector 213. The mounting wall 211 and the base 212 form a mounting cavity (not shown in the figure). The iron ring 24 and the first magnetic ring 221 are disposed at the open end of the mounting wall 211. The base 212 is located at the bottom of the mounting wall 211. The rotating shaft connector 213 is disposed at the center of the base 212 for connecting the rotating shaft of the pump in the pump device (not shown in the figure). The second magnetic ring 231 is disposed on the upper end surface of the base 212 and surrounds the rotating shaft connector 213.

[0060] In some embodiments, reference Figure 5 The second magnet ring 231 is disposed on the first horizontal plane, and the first magnet ring 221 is disposed on the second horizontal plane. The axial distance H between the first horizontal plane and the second horizontal plane is not less than 5 mm. This specific distance H ensures that the second magnet ring 231 and the first magnet ring 221 do not interfere with each other.

[0061] In some specific embodiments, the axial distance H between the first horizontal plane and the second horizontal plane is 8.5 mm. This ensures that the second magnet ring 231 and the first magnet ring 221 do not interfere with each other, and also prevents the axial distance H between the first horizontal plane and the second horizontal plane from being too large, thus avoiding increasing the volume of the magnetic ring seat assembly. Of course, in other embodiments, the distance H can be selected as a value between 5 mm and 8.5 mm, for example, 5.5 mm or 6 mm, or, depending on actual needs, H can be selected as greater than 8.5 mm.

[0062] Figure 6 for Figure 5 A partial structural diagram of A in the magnetic ring seat assembly shown.

[0063] In some embodiments of this application, reference is made to Figures 3 to 6 The mounting wall 211 has an opening end with a mounting platform 2111. The first magnet 22 is disposed on the mounting platform 2111, and the end of the first magnet 22 away from the mounting platform 2111 is inclined to the outside of the mounting wall 211. The acute angle α formed between the bottom of the first magnet 22 and the mounting platform 2111 is greater than or equal to 5° and less than or equal to 10°. The selection of this angle is beneficial for the first magnet 22 to provide effective and reliable axial force and radial force, so that the first magnet 22 can maintain dynamic balance during operation.

[0064] In some specific embodiments of this application, the acute angle α formed between the bottom of the first magnet 22 and the mounting platform 2111 is 6°, 7°, 8.5° or 9°, etc.

[0065] In some embodiments of this application, reference is made to Figures 3 to 6 The iron ring 24 is disposed on the mounting platform 2111, and the central axis of the iron ring 24 is perpendicular to the mounting platform 2111. The radial thickness of the iron ring 24 gradually decreases in the direction away from the mounting platform 2111. This is beneficial for the first magnet 22 to be disposed at an angle on the mounting platform 2111, while providing more effective and reliable axial and radial forces.

[0066] In some specific embodiments of this application, reference is made to Figure 3 The upper surface of the base 212 is provided with a plurality of reinforcing ribs 25, and the plurality of reinforcing ribs 25 are arranged at equal intervals. The arrangement of the plurality of reinforcing ribs 25 is beneficial to improving the strength of the base 212.

[0067] In some embodiments of this application, reference is made to Figure 3 and Figure 4The central axis of the iron ring 24, the central axis of the first magnet ring 221, and the central axis of the second magnet ring 231 coincide. When a ray parallel to the central axis of the iron ring 24 projects onto the iron ring 24, the first magnet ring 221, and the second magnet ring 231, the projection of the iron ring 24 is located on the outer circumference of the projection of the first magnet ring 221, and the projection of the second magnet ring 231 is located on the inner circumference of the projection of the first magnet ring 221. Figure 4 A top view of the magnetic ring assembly is shown. Specifically, the diameter of the iron ring 24 is larger than the diameter of the first magnetic ring 221, and the diameter of the second magnetic ring 231 is smaller than the diameter of the first magnetic ring 221.

[0068] In some embodiments of this application, reference is made to Figures 3 to 5 The first magnet ring 221 is disposed against the iron ring 24, and the second magnet ring 231 is disposed at a distance from the first magnet ring 221 and is disposed near the center of the magnet ring seat 21.

[0069] In some specific embodiments of this application, reference is made to Figures 3 to 5 The first magnet 22 has an arc-shaped structure, and multiple first magnets 22 are arranged at equal intervals around the center of the magnetic ring seat 21 to form the first magnet ring 221.

[0070] In some specific embodiments of this application, reference is made to Figures 3 to 5 The first magnetic ring 221 includes eight first magnets 22. The radius of curvature R1 of the outer wall of each first magnet 22 is 29.5 mm, the radius of curvature R2 of the inner wall is 27.5 mm, and the height is 5 mm. The central angle β of each first magnet 22, i.e., the angle β between the lines connecting the two ends of each first magnet 22 to the center of the magnetic ring seat, is 45°. The spacing between adjacent first magnets 22 is 3 mm. This design facilitates ideal magnetic attraction between the first annular component formed by the first magnetic ring 221 and the iron ring 24, and the single magnetic ring in the pump head. If the dimensions of the first magnet 22 are too large, the high magnetic field strength, magnetic moment, and magnetic force will result in excessive friction between the first magnet 22 and other structures, thus shortening the product's lifespan. If the dimensions of the first magnet 22 are too small, the low magnetic field strength, magnetic moment, and magnetic force will affect the magnetic coupling between the first annular component and the single magnetic ring in the pump head.

[0071] Wherein, the radius of curvature R1 of the outer wall of the first magnet 22 refers to the distance between the outer wall of the first magnet 22 and the center of the magnetic ring seat 21, and the radius of curvature R2 of the inner wall of the first magnet 22 refers to the distance between the inner wall of the first magnet 22 and the center of the magnetic ring seat 21.

[0072] In some specific embodiments of this application, reference is made to Figures 3 to 5 The second magnet 23 has an arc-shaped structure, and multiple second magnets 23 are arranged at equal intervals around the center of the magnetic ring seat 21 to form the second magnet ring 231.

[0073] In some specific embodiments of this application, reference is made to Figures 3 to 5 The second magnetic ring 231 includes eight second magnets 23. The radius of curvature R3 of the outer wall of each second magnet 23 is 19.5 mm, the radius of curvature R4 of the inner wall is 14.5 mm, and the height is 2.5 mm. The central angle γ of each second magnet 23, i.e., the angle between the lines connecting the two ends of each second magnet 23 to the center of the magnetic ring seat 21, is 60°. The spacing between adjacent second magnets 23 is 1 mm. This facilitates ideal magnetic attraction between the second annular component formed by the second magnetic ring 231 and the iron ring 24, and the double magnetic ring in the pump head. If the dimensions of the second magnet 23 are too large, the high magnetic field strength, magnetic moment, and magnetic force will result in excessive friction between the second magnet 23 and other structures, thus shortening the product's lifespan. If the dimensions of the second magnet 23 are too small, the low magnetic field strength, magnetic moment, and magnetic force will affect the magnetic coupling between the second annular component and the double magnetic ring in the pump head.

[0074] Wherein, the radius of curvature R3 of the outer wall of the second magnet 23 refers to the distance between the outer wall of the second magnet 23 and the center of the magnetic ring seat 21, and the radius of curvature R4 of the inner wall of the second magnet 23 refers to the distance between the inner wall of the second magnet 24 and the center of the magnetic ring seat 21.

[0075] The transmission device of the pump assembly of this application will be further described below.

[0076] In some embodiments of this application, the transmission device includes a first drive mechanism, a second drive mechanism, a rotating mechanism, a first transmission mechanism, and a second transmission mechanism. The first drive mechanism is connected to the rotating mechanism via the first transmission mechanism, and the second drive mechanism is connected to the rotating mechanism via the second transmission mechanism. The first drive mechanism and the second drive mechanism are used to selectively drive the rotating mechanism to rotate. When the first drive mechanism drives the rotating mechanism to rotate, the second drive mechanism remains in a closed or running state; when the second drive mechanism drives the rotating mechanism to rotate, the first drive mechanism remains in a closed or running state. The transmission device integrates two drive mechanisms, allowing it to operate under the drive of either drive mechanism, saving time on changing drive mechanisms, reducing the risk of rescue errors, and reducing the need for redundant mechanisms. The integration of the two drive mechanisms reduces the overall weight of the transmission device and medical pump, thereby reducing the burden on medical personnel during outdoor emergency rescue and the cost of material management. Moreover, the two drive mechanisms do not interfere with each other and can operate independently.

[0077] In some specific embodiments of this application, when the first driving mechanism provides driving force, the first driving mechanism drives the rotating part in the first transmission mechanism to rotate. At this time, the rotating part in the first transmission mechanism and the connecting part in the first transmission mechanism are in a linked state, so that the connecting part in the first transmission mechanism rotates with the rotating part in the first transmission mechanism, thereby driving the rotating mechanism connected to the rotating part in the first transmission mechanism to rotate. The rotation of the rotating mechanism will drive the connecting part in the second transmission mechanism connected to the rotating mechanism to rotate. However, since the rotating part in the second transmission mechanism and the connecting part in the second transmission mechanism are in an idle state at this time, the rotating part in the second transmission mechanism will not rotate with the connecting part in the second transmission mechanism. That is, the first transmission mechanism can transmit the driving force of the first driving mechanism to the rotating mechanism, but the driving force transmitted by the first driving mechanism to the rotating mechanism cannot be transmitted to the second driving mechanism through the second transmission mechanism. At this time, the second driving mechanism remains in a closed or running state, that is, the first transmission mechanism performs unidirectional power transmission, realizing that when the first transmission mechanism drives the rotating mechanism to rotate, it will not interfere with or affect the operation and opening and closing of the second driving mechanism.

[0078] In other specific embodiments of this application, when the second driving mechanism provides driving force, the second driving mechanism drives the rotating part in the second transmission mechanism to rotate. At this time, the rotating part in the second transmission mechanism and the connecting part in the second transmission mechanism are in a linked state, so that the connecting part in the second transmission mechanism rotates with the rotating part in the second transmission mechanism, thereby driving the rotating mechanism connected to the rotating part in the second transmission mechanism to rotate. The rotation of the rotating mechanism will drive the connecting part in the first transmission mechanism connected to the rotating mechanism to rotate. However, since the rotating part in the first transmission mechanism and the connecting part in the first transmission mechanism are in an idle state at this time, the rotating part in the first transmission mechanism will not rotate with the connecting part in the first transmission mechanism. That is, the second transmission mechanism can transmit the driving force of the second driving mechanism to the rotating mechanism, but the driving force transmitted by the second driving mechanism to the rotating mechanism cannot be transmitted to the first driving mechanism through the first transmission mechanism. At this time, the first driving mechanism remains in a closed or running state, that is, the second transmission mechanism performs unidirectional power transmission, realizing that when the second transmission mechanism drives the rotating mechanism to rotate, it will not interfere with or affect the operation and opening and closing of the first driving mechanism.

[0079] In some embodiments of this application, the direction in which the first driving mechanism drives the rotating shaft to rotate is the same as the direction in which the second driving mechanism drives the rotating shaft to rotate. Specifically, please refer to... Figures 7 to 9 The following describes the transmission device. Figure 7 for Figure 1 A schematic diagram of the pump base assembly and display module in the pump device shown; Figure 8 for Figure 1 The side view of the pump unit shown; Figure 9 for Figure 8 The pump assembly shown is a cross-sectional view along line B-B1.

[0080] In some embodiments of this application, the rotating mechanism includes a first transmission part, a second transmission part, a main transmission part, and a rotating shaft, and the main transmission part is respectively connected to the first transmission part and the second transmission part. The transmission connection can be either a gear transmission connection or a belt transmission connection.

[0081] In some specific embodiments of this application, the transmission connection is a gear transmission connection; for details, please refer to... Figure 7 and Figure 9The first transmission part includes a first transmission gear 111, the second transmission part includes a second transmission gear 113, and the main transmission part includes a main transmission gear 112. The main transmission gear 112 meshes with both the first transmission gear 111 and the second transmission gear 113 to achieve gear transmission connection. That is, the rotating mechanism (not shown in the figure) includes the first transmission gear 111, the main transmission gear 112, the second transmission gear 113, and a rotating shaft 114. The main transmission gear 112 is sleeved on the rotating shaft 114, and the rotating shaft 114 is connected to the rotating shaft connector 213 in the magnetic ring seat 21. The rotating mechanism has a simple structure, few parts, reduces the overall weight of the transmission device, is easy to assemble, and lowers investment costs.

[0082] In some embodiments of this application, the first transmission mechanism is a first one-way bearing, and the second transmission mechanism is a second one-way bearing. The direction of the driving force transmitted by the first one-way bearing is from the first driving mechanism to the rotating mechanism, and the direction of the driving force transmitted by the second one-way bearing is from the second driving mechanism to the rotating mechanism. The one-way bearing is a type of bearing that can only rotate in one direction; that is, it can rotate freely in one direction (free-spinning) while locking in the other direction to transmit torque. One-way bearings are also called overrunning clutches, but the name varies depending on the industry and its function. The metal housing of a one-way bearing contains many rollers, needle rollers, or balls, and the shape of its rolling seat or rolling cavity allows it to roll only in one direction, while generating significant resistance in the other direction—hence the term "one-way." One-way bearings have a simple structure, fewer parts, reduce the overall weight of the transmission device, are easy to assemble, and lower investment costs.

[0083] In some specific embodiments of this application, reference is made to Figure 7 and Figure 9The first drive mechanism (not shown in the figure) includes the motor 121 and a drive shaft 122 connected to the motor 121. A first one-way bearing 131 is sleeved on the drive shaft 122, and a first transmission gear 111 is sleeved on the first one-way bearing 131, with the first one-way bearing 131 and the first transmission gear 111 engaging. The second drive mechanism (not shown in the figure) includes a transmission assembly (not shown in the figure) and an external force drive unit (not shown in the figure). The transmission assembly (not shown in the figure) includes a gearbox 141 and a rotating shaft 142 connected to the gearbox 141, with the gearbox 141 connected to the external force drive unit (not shown in the figure). A second one-way bearing 151 is sleeved on the rotating shaft 142, and a second transmission gear 113 is sleeved on the second one-way bearing 151, with the second one-way bearing 151 and the second transmission gear 113 engaging. The rotation mechanism (not shown in the figure) transmits the power from the motor 121 or the gearbox 141 to the magnetic ring seat assembly.

[0084] In some possible embodiments of this application, the external force driving unit includes at least one of a manual driving unit and a foot pedal driving unit. Specifically, the external force driving unit includes at least one of a hand crank handle and a foot pedal actuator.

[0085] In some specific embodiments of this application, reference is made to Figure 1 The external force driving unit is a foldable handle 15, which includes a first handle 1501 and a second handle 1502, which are movably connected. In manual mode, after the foldable handle 15 is removed and unfolded, rotating the foldable handle 15 will drive the rotating shaft 142 connected to the transmission 141 to rotate. This allows the power accelerated by the transmission 141 to be transmitted to the rotating shaft 114 through the second transmission gear 113 and the main transmission gear 112, thereby enabling the pump device to operate in manual mode.

[0086] In some possible embodiments of this application, the electric drive unit is a motor. The specific structure and performance of the motor are conventional in the art and will not be described in detail here.

[0087] In some specific embodiments of this application, the motor is a DC brushless motor.

[0088] Figure 10 This is a schematic diagram of the assembly of the first one-way bearing with the drive shaft and the first transmission gear according to an embodiment of this application; Figure 11 This is a schematic diagram of the assembly of the second one-way bearing, the rotating shaft, and the second transmission gear according to an embodiment of this application.

[0089] In some specific embodiments of this application, the one-way bearing has a ring structure, the rotating part is an inner ring body, the connecting part is an outer ring body, and the inner ring body and the outer ring body are coaxially connected. (Reference) Figures 9 to 11 The first one-way bearing 131 includes a first inner ring 1311 and a first outer ring 1312. The first inner ring 1311 is connected to the drive shaft 122, and the first outer ring 1312 is engaged with the first transmission gear 111. The second one-way bearing 151 includes a second inner ring 1511 and a second outer ring 1512. The second inner ring 1511 is connected to the rotating shaft 142, and the second outer ring 1512 is engaged with the second transmission gear 113.

[0090] For details, please refer to Figures 9 to 11 The transmission device described in this application can realize the following two working scenarios.

[0091] Scenario 1: When the motor 121 is working, the drive shaft 122 rotates clockwise, driving the first one-way bearing 131 to rotate. At this time, the first inner ring 1311 and the first outer ring 1312 of the first one-way bearing 131 are locked together, achieving linkage. This ensures that when the drive shaft 122 rotates clockwise, the first inner ring 1311 and the first outer ring 1312 rotate clockwise together, transmitting the torque of the drive shaft 122 to the first transmission gear 111. In other words, the motor 121 drives the first transmission gear 111 to rotate through the first one-way bearing 131, thus enabling the first one-way bearing 131 to drive the first transmission gear 111 to rotate clockwise. Then, the first transmission gear 111 transmits power to the main transmission gear 112, which meshes with it. The main transmission gear 112 drives the rotating shaft 114 to rotate counterclockwise, thereby outputting torque. Simultaneously, the main drive gear 112 transmits power to the second drive gear 113, which meshes with the main drive gear 112, causing the second drive gear 113 to rotate clockwise. At this time, the second inner ring 1511 and the second outer ring 1512 in the second one-way bearing 151 between the second drive gear 113 and the rotating shaft 142 slide relative to each other. That is, the second drive gear 113 drives the second outer ring 1512 to rotate, but the second outer ring 1512 and the second inner ring 1511 idle and do not transmit power to the rotating shaft 142, thus preventing the rotating shaft 142 of the transmission 141 from rotating. This achieves the effect that the motor 121 does not interfere with the operation of the transmission 141.

[0092] Scenario 2: When the user provides manual driving force using the external force drive unit, the external force drive unit inputs torque to the transmission 141, causing the rotating shaft 142 of the transmission 141 to rotate clockwise. The rotating shaft 142 drives the second one-way bearing 151 to rotate. At this time, the second inner ring 1511 and the second outer ring 1512 in the second one-way bearing 151 are locked together to achieve linkage. Thus, when the rotating shaft 142 rotates clockwise, the second inner ring 1511 and the second outer ring 1512 rotate clockwise together to transmit the torque of the rotating shaft 142 to the second transmission gear 113. That is, at this time, the transmission 141 drives the second transmission gear 113 to rotate through the second one-way bearing 151, so that the second one-way bearing 151 can drive the second transmission gear 113 to rotate clockwise. Then, the second transmission gear 113 transmits power to the main transmission gear 112 meshing with it. The main transmission gear 112 drives the rotating shaft 114 to rotate counterclockwise, thereby outputting torque. Simultaneously, the main transmission gear 112 transmits power to the first transmission gear 111 meshing with it, causing the first transmission gear 111 to rotate clockwise. At this time, the first inner ring 1311 and the first outer ring 1312 in the first one-way bearing 131 between the first transmission gear 111 and the drive shaft 122 slide relative to each other. That is, the first transmission gear 111 drives the first outer ring 1312 to rotate, but the first inner ring 1311 and the first outer ring 1312 idle without transmitting power to the drive shaft 122, so that the drive shaft 122 of the motor 121 does not rotate. This achieves the effect that the transmission 141 does not interfere with the operation of the motor 121.

[0093] By cooperating with the first transmission gear 111, the main transmission gear 112, the second transmission gear 113, the first one-way bearing 131, and the second one-way bearing 151, when the motor 121 provides electric driving force, the drive shaft 122 sequentially drives the first one-way bearing 131, the first transmission gear 111, the main transmission gear 112, and the second transmission gear 113 to rotate. Because the second one-way bearing 151 is a one-way transmission, the electric driving force provided by the motor 121 will not be transmitted to the transmission 141. When the external driving unit (not shown in the figure) provides manual driving force to make the transmission 141 operate, the rotating shaft 142 sequentially drives the second one-way bearing 151, the second transmission gear 113, the main transmission gear 112, and the first transmission gear 111 to rotate. Because the first one-way bearing 131 is a one-way transmission, the manual driving force provided by the external driving unit (not shown in the figure) will not be transmitted to the motor 121. That is, the motor 121, the external force drive unit (not shown in the figure), and the transmission 141 are combined in the same pump. However, when the motor 121 drives the main transmission gear 112 to rotate, it will not interfere with the opening and closing and movement state of the transmission 141. When the external force drive unit (not shown in the figure) and the transmission 141 cooperate to drive the main transmission gear 112 to rotate, they will not interfere with the opening and closing and movement state of the motor 121. The two drive mechanisms achieve independent operation. The user can freely choose to start either the motor 121 or the external force drive unit (not shown in the figure) to drive the main transmission gear 112 to rotate as needed. Furthermore, the integration of the electric and manual drive mechanisms optimizes the product model. The manual drive function, integrated into the electric pump, can serve as a backup power source. In situations where power is unavailable during prolonged outdoor rescue operations, the electric drive can be quickly and easily switched to manual drive, achieving seamless switching of the drive mechanism. This eliminates the need for manual disassembly and installation of the pump, saving time on pump replacement, reducing the risk of rescue errors, and minimizing the need for redundant mechanisms. The overall size and weight of the pump can remain largely unchanged, reducing the burden on medical personnel during outdoor emergency rescues and material management costs. This also solves the inconvenience of carrying and switching between two pumps simultaneously in emergencies, reducing the risk of errors by medical personnel when switching pumps.

[0094] The above scenario uses the example of driving the rotating shaft 114 to rotate counterclockwise. In other embodiments, the rotating shaft 114 can also be driven to rotate clockwise. The specific setting method can be adapted to the rotation direction of the above scenario, and will not be described in detail here.

[0095] In other possible embodiments of this application, the transmission connection is a belt drive connection, the first transmission part includes a first transmission pulley, the second transmission part includes a second transmission pulley, the main transmission part includes a main transmission pulley, and any one of the first transmission part, the second transmission part and the main transmission part further includes a belt or a toothed belt, and the main transmission gear, the first transmission gear and the second transmission gear are connected by the belt or the toothed belt to realize the belt drive connection.

[0096] In some specific embodiments of this application, reference is made to Figure 7 and Figure 9 The motor 121 and the gearbox 141 are defined by a portion of the pump housing 17 and fixedly mounted within the pump housing 17 by mounting screws. Specifically, the pump housing 17 is a mounting housing.

[0097] In some specific embodiments of this application, reference is made to Figure 7 and Figure 9 The first transmission gear 111 has a first washer 1111 and a first baffle 1112 respectively provided on its bottom and top surfaces to limit its vertical movement. The second transmission gear 113 has a second washer 1131 and a first retaining ring 1132 provided on its top and bottom surfaces to limit its vertical movement. The rotating shaft 114 is connected to the ball bearing 1121 and is disposed within the pump housing 17 to ensure coaxiality and smooth rotation. The top surface of the main transmission gear 112 has a third washer 1122 and a second retaining ring 1123 to limit its upper movement; the bottom of the main transmission gear 112 abuts against the shoulder of the rotating shaft 114 to limit its lower movement.

[0098] In some possible embodiments of this application, the first gasket 1111, the second gasket 1131, and the third gasket 1122 are all wear-resistant gaskets with a low coefficient of friction.

[0099] In other possible embodiments of this application, the first gasket 1111, the second gasket 1131 and the third gasket 1122 can all be replaced with end face bearings to increase wear resistance and reduce friction.

[0100] In some embodiments of this application, the transmission device further includes a power generation component, which is connected to the transmission component and is used to supply power to the electrical components. Even after a power outage, the transmission component can still be driven to rotate by an external force drive unit. In this case, the transmission component transmits the driving force to the power generation component, causing the power generation component to operate and generate electricity. This allows power to be supplied to the electrical components through manual driving force, ensuring the basic operation of the power supply components.

[0101] Specifically, when the electric drive unit in the first drive mechanism is underpowered or malfunctioning, the external drive unit in the second drive mechanism is directly removed and installed on the transmission. The transmission is then driven by the hand-cranked drive unit or the foot pedal drive unit, causing the rotating shaft to rotate, which in turn drives the rotating mechanism and the power generation component to generate electricity. After the electric drive unit regains power, because the electric drive unit drives the rotating mechanism to rotate quickly, the rotating mechanism rotates along with the faster-rotating drive unit, thus rotating under the drive of the electric drive unit. At this time, the transmission continues to operate under the hand-cranked drive unit or the foot pedal drive unit, thereby driving the rotating shaft to rotate and causing the power generation component to generate electricity. Since the rotation of the rotating shaft only drives the power generation component to generate electricity, it is relatively less strenuous. At this time, the first drive mechanism drives the rotating mechanism to rotate, while the second drive mechanism remains in the off state. Alternatively, the hand-cranked drive unit or the foot pedal drive unit can be removed to stop driving the transmission; that is, the operation of the first drive mechanism will not affect the off or active state of the second drive mechanism.

[0102] In some embodiments of this application, the electrical components include display modules and indicator lights, etc.

[0103] In some specific embodiments of this application, the indicator light includes at least one of an indicator light indicating whether the pump is working, an indicator light indicating whether the rotating shaft is rotating, and an indicator light indicating the pump speed.

[0104] In some embodiments of this application, the transmission connection between the power generation component and the transmission component includes either a gear transmission connection or a belt transmission connection.

[0105] In some embodiments of this application, the power generation component includes a generator, a generator transmission part, and a third transmission part. The generator is connected to the generator transmission part, the third transmission part is connected to the rotating shaft, and the generator transmission part is drivingly connected to the third transmission part.

[0106] In some specific embodiments of this application, the transmission is used to amplify the rotational speed of the hand crank, and the transmission ratio is at least 1:30.

[0107] In some possible embodiments of this application, the generator is a micro-motor. The micro-motor is small in size and capacity, and its output power is generally below several hundred watts.

[0108] In some specific embodiments of this application, the generator includes any one of the following: DC motor, AC motor, self-regulating angle motor, stepper motor, rotary transformer, shaft angle encoder, AC / DC universal motor, tachogenerator, inductive synchro, linear motor, piezoelectric motor, motor unit, and other special motors.

[0109] In some embodiments of this application, the power generation assembly further includes a fourth transmission unit, which is connected to both the generator transmission unit and the third transmission unit. This achieves a two-stage transmission, reduces installation space, and effectively avoids interference with the operation of other components.

[0110] In some specific embodiments of this application, the power generation component and the transmission component are connected by gear transmission; that is, the generator transmission part includes a generator transmission gear, the third transmission part includes a third transmission gear, and the fourth transmission part includes a fourth transmission gear and a transmission shaft. (Reference) Figure 7 and Figure 9 The generator drive gear 161 is sleeved on the output shaft 163 of the generator 162, the third drive gear 164 is sleeved on the rotating shaft 142, and the fourth drive gear 165 is sleeved on the drive shaft 166. The generator 162 and the drive shaft 166 are fixedly mounted on the pump housing 17. The fourth drive gear 165 meshes with the generator drive gear 161 and the third drive gear 164 respectively. The third drive gear 164 is coaxially arranged with the second drive gear 113. When the external force drive unit (not shown in the figure) drives the transmission 141 to move, thereby driving the rotating shaft 142 to rotate, the third drive gear 164 and the second drive gear 113 rotate with the rotating shaft 142, thereby transmitting the manual driving force to the rotating shaft 114 and the output shaft 163 respectively, so as to drive the rotating shaft 114 to rotate and drive the generator 162 to run.

[0111] For details, please refer to Figure 9 The bottom and top surfaces of the fourth transmission gear 165 are each provided with a third retaining ring 1651.

[0112] In other embodiments of this application, the generator drive unit includes a generator pulley, the third drive unit includes a third pulley, and either the generator drive unit or the third drive unit further includes a belt or a toothed belt. The generator pulley and the third pulley are connected by the belt or the toothed belt. This reduces the installation space.

[0113] In other embodiments of this application, the structures of the first driving mechanism and the second driving mechanism are identical. Both the first and second driving mechanisms include an electric driving unit and a drive shaft. The electric driving unit is connected to the drive shaft and provides electric driving force. The rotating part in the first transmission mechanism is disposed on the drive shaft in the first driving mechanism, and the rotating part in the second transmission mechanism is disposed on the drive shaft in the second driving mechanism. Either the first or the second driving mechanism can be used as a backup driving mechanism, so that if one driving mechanism fails, the rotating mechanism can still be driven to rotate by the other driving mechanism.

[0114] In some possible embodiments of this application, the transmission device further includes a switching mechanism for switching the opening and closing of the first drive mechanism and the second drive mechanism.

[0115] While the embodiments of this application have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of this application as set forth in the claims. Furthermore, the application described herein may have other embodiments and can be implemented or carried out in various ways.
