Description

Technical Field

[0001] This utility model relates to the technical field of breast pumps, and specifically to a quick-release assembly mechanism for a breast pump. Background Technology

[0002] As an aid in infant feeding, the core function of a baby shaker is to rotate the bottle using a cradle to fully dissolve the formula. However, existing designs have significant shortcomings in terms of cleaning and maintenance. Specifically, the bottom of the bottle needs to be placed inside the cradle. If the bottom of the bottle gets dirty and the user doesn't wipe it before placing it on the cradle, the cradle will also become dirty during operation. Furthermore, the cradle is usually fixed with screws, requiring the user to unscrew it to remove it from the main body of the shaker. Some users are unwilling to disassemble the cradle and wash it directly on the machine. Because the cradle is tightly connected to the body and the internal space is small, it's difficult for users to reach the corners and crevices during cleaning, leading to long-term accumulation of dirt.

[0003] In addition, the cradle of a breast pump is usually made of plastic, which easily attracts stains and is difficult to wipe clean. Due to structural limitations, users can only use wet wipes or a small brush for spot cleaning and cannot rinse thoroughly. Utility Model Content

[0004] This invention proposes a quick-release mechanism for a baby shaker. By movably mounting the connecting arm on the bottle holder, the connection between the bottle holder and the shaking mechanism becomes detachable. When cleaning is required, the bottle holder can be easily detached from the shaking mechanism. This design completely solves the problem of cumbersome disassembly caused by turning screws when disassembling the cradle in existing technologies. Furthermore, eliminating the screw fixing structure improves assembly efficiency.

[0005] A quick-release mechanism for a milk shaker designed for this purpose includes:

[0006] The main unit is equipped with a milk shaking mechanism;

[0007] A bottle rack, wherein the bottle rack has an internal section for accommodating baby bottles;

[0008] The connecting arm is detachably connected to the milk shaking mechanism. The connecting arm is movably mounted on the bottle holder. When the connecting arm is locked to the milk shaking mechanism, the bottle holder is positioned on the milk shaking mechanism. When the connecting arm is disassembled from the milk shaking mechanism, the bottle holder can be separated from the milk shaking mechanism.

[0009] The bottle rack has open sections at both the top and bottom, and the two ends of the bottle rack are connected.

[0010] The connecting arm is elastically rotatably mounted on the bottle holder, and there are two connecting arms, which are respectively located on the left and right sides of the bottle holder;

[0011] The upper part of the connecting arm is rotatably connected to the bottle holder, and the lower part of the connecting arm is detachably connected to the milk shaking mechanism.

[0012] The bottle holder and the connecting arm are provided with an inner gap for the connecting arm to rotate. During the rotation of the connecting arm, the inner gap between the bottle holder and the connecting arm gradually decreases.

[0013] The milk shaking mechanism includes a movable tray, and a fastening structure is provided between the tray and the connecting arm;

[0014] In the locked state, the connecting arm is fixedly connected to the tray via a snap-fit ​​structure;

[0015] In the detached state, the connecting arm can be easily detached from the tray;

[0016] The fastening structure includes a fastening hole on the tray and a buckle on the connecting arm; the connecting arm is fixedly connected to the tray, and the buckle fastens to the fastening hole.

[0017] The bottle holder has a notch at the connection point between the tray and the connecting arm.

[0018] A rotatable connection structure is provided between the bottle holder and the connecting arm, and the connecting arm is rotatably connected to the bottle holder through the rotatable connection structure.

[0019] The rotating connection structure includes a connecting ear on the bottle holder and a bushing on the connecting arm. The bushing abuts against the inner side of the connecting ear, and a connecting shaft is inserted between the connecting ear and the bushing. When the connecting arm rotates, it rotates around the axis of the connecting shaft, and the connecting shaft forms the rotation fulcrum of the connecting arm.

[0020] An elastic element is also provided between the bottle holder and the connecting arm. The elastic element has a connecting part sleeved on the outside of the connecting shaft. The first end of the elastic element elastically abuts against the outside of the bottle holder, and the second end of the elastic element elastically abuts against the inside of the connecting arm, so as to realize the elastic rotation of the connecting arm on the bottle holder.

[0021] The bottle holder has a limiting groove on its outer side, and the first end of the elastic element is installed on the limiting groove.

[0022] The bottle holder has a slot on its outer side, and the connecting arm has an extension block on the upper part of its bushing. The extension block has an inner cavity. The extension block of the connecting arm is installed in the slot. An inner distance is formed between the extension block and the slot to allow the connecting arm to rotate. An installation cavity is formed between the extension block and the slot to accommodate the installation of the elastic element. When the connecting arm rotates, the elastic element is limited and deformed within the installation cavity.

[0023] The inner side of the bottle holder is provided with elastic blocks for elastically holding the bottle. There are several elastic blocks arranged in a circularly spaced array on the inner side of the bottle holder.

[0024] The bottle rack is equipped with vents for the intake of hot air.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0037] See Figures 1-9 A quick-release mechanism for a breast pump includes:

[0038] Main unit 21, wherein the main unit 21 is equipped with a milk shaking mechanism;

[0039] Bottle rack 1, wherein the bottle rack 1 has an internal section for accommodating baby bottles;

[0040] The connecting arm 2 is detachably connected to the milk shaking mechanism. The connecting arm 2 is movably mounted on the bottle holder 1. When the connecting arm 2 is locked to the milk shaking mechanism, the bottle holder 1 is positioned on the milk shaking mechanism. When the connecting arm 2 is disassembled from the milk shaking mechanism, the bottle holder 1 can be separated from the milk shaking mechanism.

[0041] The bottle holder 1 has an open portion 1.1 at both the upper and lower ends, and the upper and lower ends of the bottle holder 1 are in a through state. The open upper and lower ends of the bottle holder 1 facilitate cleaning. After the user removes the bottle holder 1, the inner cavity of the main unit 21 where the bottle holder 1 is installed becomes wider, and the user can reach into the inner cavity to wipe the tray 3.

[0042] By movably mounting the connecting arm 2 onto the bottle holder 1, the connection between the bottle holder 1 and the shaking mechanism becomes detachable. When cleaning is required, the bottle holder 1 can be easily detached from the shaking mechanism. This design completely solves the problem of cumbersome disassembly caused by turning screws when removing the cradle in existing technologies. Users can move the bottle holder 1 to a suitable location, such as the sink, for a thorough cleaning, no longer limited by the confined internal space of the shaker. Furthermore, the connecting arm 2, fastened to one end of the shaking mechanism, ensures a stable transmission connection between the bottle holder 1 and the shaking mechanism during operation, guaranteeing the normal operation of the shaking process. This movable mounting and fastening connection not only improves the convenience of cleaning and maintenance but also ensures stability during use, providing users with great convenience and significantly improving the user experience and hygiene of the shaker.

[0043] The connecting arm 2 is elastically rotatably mounted on the bottle holder 1. There are two connecting arms 2, which are respectively mounted on the left and right sides of the bottle holder 1.

[0044] The upper part of the connecting arm 2 is rotatably connected to the bottle holder 1, and the lower part of the connecting arm 2 is detachably connected to the milk shaking mechanism;

[0045] The bottle holder 1 and the connecting arm 2 are provided with an inner distance 6 for the connecting arm 2 to rotate. During the rotation of the connecting arm 2, the inner distance 6 between the bottle holder 1 and the connecting arm 2 gradually decreases.

[0046] Due to the elastic rotation characteristics of the connecting arm 2, users can easily engage it with the milk-shaking mechanism. When the connecting arm 2 approaches the corresponding connection point on the milk-shaking mechanism, it remains engaged with one end of the mechanism under the action of elastic force. For disassembly, the user only needs to apply a certain external force to make the connecting arm 2 rotate against the elastic force, thus detaching it from the milk-shaking mechanism – a simple operation. Furthermore, during the rotation of the connecting arm 2, the inner distance 6 between the bottle holder 1 and the connecting arm 2 gradually decreases, providing space for the user to press the connecting arm 2. When the user presses the connecting arm 2, one end of the connecting arm 2 gradually moves closer to the bottle holder 1, thus gradually reducing the inner distance 6 between the bottle holder 1 and the connecting arm 2.

[0047] The milk shaking mechanism includes a movable tray 3, and a fastening structure is provided between the tray 3 and the connecting arm 2;

[0048] In the locked state, the connecting arm 2 is fixedly connected to the tray 3 via a fastening structure;

[0049] In the detached state, connecting arm 2 can be detached from tray 3;

[0050] The fastening structure includes a fastening hole 4 on the tray 3 and a buckle 5 on the connecting arm 2; the connecting arm 2 is fixedly connected to the tray 3, and the buckle 5 fastens to the fastening hole 4.

[0051] The snap-fit ​​structure makes the connection between the connecting arm 2 and the tray 3 simple and reliable. When the shaker is working, the buckle 5 and the snap-fit ​​hole 4 are tightly engaged, effectively transmitting power and ensuring that the bottle rack 1 moves stably with the tray 3, thus guaranteeing the shaking effect. When it is necessary to clean the bottle rack 1, the user can easily move the connecting arm 2 to disengage the buckle 5 from the snap-fit ​​hole 4, separating the connecting arm 2 from the tray 3, and then removing the bottle rack 1 from the shaking mechanism for cleaning. In addition, the movable tray 3 can adapt to different working needs to a certain extent. For example, when adjusting the placement or angle of the shaker, the movable nature of the tray 3 can reduce the impact of positional changes on the bottle rack 1 and the connecting structure, further improving the flexibility and stability of the shaker.

[0052] The tray 3 is provided with a bottom cover, and the lower part of the bottle rack 1 is supported on the bottom cover. The bottom cover covers the open part 1.1 at the bottom of the bottle rack 1.

[0053] The milk shaking mechanism also includes a motor drive assembly. The output end of the motor drive assembly is connected to the tray 3 to drive the tray 3 to rotate. The motor drive assembly can be directly connected to the tray 3, or it can indirectly drive the tray 3 by means of belt drive or chain drive.

[0054] The bottle holder 1 has an avoidance notch 7 at the fastening point between the tray 3 and the connecting arm 2.

[0055] When the connecting arm 2 and the tray 3 are fastened together, the clearance notch 7 can prevent the structure of the bottle holder 1 from obstructing the fastening action, so that the buckle 5 on the connecting arm 2 can be fastened smoothly with the fastening hole 4 on the tray 3, which improves the convenience and ease of installation.

[0056] A rotatable connection structure is provided between the bottle holder 1 and the connecting arm 2, and the connecting arm 2 is rotatably connected to the bottle holder 1 through the rotatable connection structure.

[0057] The rotating connection structure includes a connecting ear 8 on the bottle holder 1 and a bushing 9 on the connecting arm 2. The bushing 9 abuts against the inner side of the connecting ear 8, and a connecting shaft 10 is inserted between the connecting ear 8 and the bushing 9. When the connecting arm 2 rotates, it rotates around the axis of the connecting shaft 10, and the connecting shaft 10 forms the rotation fulcrum of the connecting arm 2.

[0058] The bottle holder 1 has two spaced connecting ears 8 on its outer side. The connecting ears 8 have a first shaft hole and the bushing 9 has a second shaft cavity. When the bottle holder 1 and the connecting arm 2 are installed, the bushing 9 is installed between the two connecting ears 8. The connecting shaft 10 is inserted into the first shaft hole and the second shaft cavity, so that the bottle holder 1 and the connecting arm 2 are rotatably connected. When the connecting arm 2 rotates, the connecting arm 2 is positioned and rotated on the outer side of the bottle holder 1.

[0059] An elastic element 11 is also provided between the bottle holder 1 and the connecting arm 2. The elastic element 11 has a connecting part 12 sleeved on the outside of the connecting shaft 10. The first end 13 of the elastic element 11 elastically abuts against the outside of the bottle holder 1, and the second end 14 of the elastic element 11 elastically abuts against the inside of the connecting arm 2, so as to realize that the connecting arm 2 can be elastically rotated on the bottle holder 1.

[0060] The presence of the elastic element 11 gives the connecting arm 2 the function of automatic reset. When the user presses the connecting arm 2 to remove the bottle holder 1, the connecting arm 2 rotates on the bottle holder 1, the elastic element 11 is compressed and stores elastic potential energy. When the removal is completed and the bottle holder 1 needs to be reinstalled, the connecting arm 2 remains fastened to the tray 3 under the elastic action of the elastic element 11.

[0061] The elastic element 11 is a torsion spring.

[0062] The bottle holder 1 has a limiting groove 15 on its outer side, and the first end 13 of the elastic element 11 is installed on the limiting groove 15.

[0063] The bottle holder 1 has an inverted U-shaped opening on its outer side, protruding from the outer side of the bottle holder 1. A limiting groove 15 is formed between the bottle holder 1 and the opening block, and the first end 13 of the elastic member 11 is limited in the limiting groove 15. The limiting groove 15 provides precise positioning for the installation of the elastic member 11, ensuring that the first end 13 of the elastic member 11 can be stably fixed on the bottle holder 1, and preventing the elastic member 11 from shifting or falling off during use.

[0064] The bottle holder 1 has a slot 16 on its outer side. The connecting arm 2 has an extension block 17 on its upper part corresponding to its bushing 9. The extension block 17 has an inner cavity 18. The extension block 17 of the connecting arm 2 is installed in the slot 16. An inner distance 6 is formed between the extension block 17 and the slot 16 to allow the connecting arm 2 to rotate. An installation cavity for accommodating the elastic element 11 is formed between the extension block 17 and the slot 16. When the connecting arm 2 rotates, the elastic element 11 is limited and deformed in the installation cavity.

[0065] The cooperation between the slot 16 and the extension block 17 provides a stable track for the rotation of the connecting arm 2, making its rotation smoother and more reliable. Combined with the design of the inner spacing 6, it better adapts to the positional changes of the connecting arm 2 during rotation. Simultaneously, the specially designed mounting cavity provides suitable installation space for the elastic element 11, allowing it to better exert its elastic effect during operation. Furthermore, the limiting deformation of the elastic element 11 within the mounting cavity during the rotation of the connecting arm 2 is effectively controlled, ensuring the normal operation of the elastic element 11 while preventing excessive deformation or displacement from affecting the performance of the connection structure. In addition, this structural design makes the entire connection part more compact and rational, improving space utilization and enhancing the overall stability of the milk shaker.

[0066] The bottle holder 1 has an elastic block 19 for elastically holding the bottle on its inner side. There are several elastic blocks 19 arranged in a circular array on the inner side of the bottle holder 1.

[0067] Several elastic blocks 19 are arranged in a circumferentially spaced array on the inner side of the bottle holder 1. During the operation of the shaker, the elastic blocks 19 can hold the bottle tightly, preventing the bottle from shaking or shifting within the bottle holder 1, thus ensuring the stability of the shaking process.

[0068] The bottle rack 1 is provided with a ventilation opening 20 for hot air to enter. The shaker is equipped with a hot air mechanism, which includes an air guide shroud, a fan installed inside the air guide shroud, and a heating element installed at the air outlet of the fan. When the hot air mechanism is working, it dries and sterilizes the bottles.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
