Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and more specifically to a neck-hanging breast pump. Background Technology

[0002] The existing neck-hook breast pump structure, such as the neck-hook breast pump disclosed in Chinese Patent Publication No. CN222738295U, includes a neck-hook main unit and a breast pump cup. The neck-hook main unit is equipped with an air pump and is connected to the breast pump cup through an air tube. The neck-hook main unit includes a neck hanging part and hanging arms connected to both sides of the neck hanging part. The free ends of the two hanging arms form a wearing opening. However, the aforementioned neck-hook breast pumps have the following structural problems: First, because different users have different body shapes and require different pump positions, and the two arms of the aforementioned breast pumps are not extendable, the position of the pump cup is not adjustable. Therefore, these breast pumps cannot meet the needs of users of different body types and are inconvenient to use. Second, the aforementioned neck-hook double breast pumps usually use silicone tubing to connect the air pump and the pump cup, which is prone to falling off during use, resulting in an unstable fixation. Moreover, other items are needed to secure the pump cup when wearing it. In addition, because the fixed position of the air pump in the aforementioned neck-hook double breast pumps is close to the user's ear, the noise emitted during use is directly transmitted to the user's ear, making it inconvenient and uncomfortable for the user to wear. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a neck-hanging breast pump with adjustable breast pumping position and convenient use.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a neck-hanging breast pump, including a neck-hanging component and one or two milk-suction components, each with an air pump; the milk-suction components are connected to the end of the neck-hanging component via an adjustable-length connector, one end of which is fixedly connected to the milk-suction component, and the other end of which is retractably inserted into the end of the neck-hanging component; the neck-hanging component has a locking component for locking the connector. This utility model breast pump adds a retractable function to the milk-suction components, allowing users to easily adjust the milk-suction position according to their body shape during use, without needing to hold the milk-suction components by hand, making it very convenient to use. This retractable breast pump can adapt to breastfeeding women of different heights and body types, and is compatible with different models of breast pumps on the market, allowing two breast pumps to work together without interfering with each other.

[0005] In a preferred embodiment, the locking component locks the connector by means of a concave-convex positioning fit or a pressing method, and the connector is a connecting strap or a connecting rope.

[0006] In a preferred embodiment, the neck assembly has an installation channel for inserting a connector. One end of the installation channel is open at the end of the neck assembly. The cross-section of the installation channel is rectangular or circular, and the connector can be locked in the installation channel by a locking component.

[0007] In a preferred embodiment, the connector is a connecting strip with multiple slots spaced apart along its length. The locking component is an elastic locking buckle, and the slots and the elastic locking buckle are positioned and matched. The structure of this utility model is reasonable and the connector is securely locked.

[0008] In a preferred embodiment, the first end of the elastic locking buckle is connected to the neck hanging component and located on one side of the connector. The second end of the elastic locking buckle is provided with a buckle, which engages with the groove to lock the connector and fix the position of the breast pump component.

[0009] In a preferred embodiment, the buckle is spherical, and there is an arc transition structure between two adjacent slots, which facilitates easy buckling and locking / unlocking of the buckle and slots.

[0010] In a preferred embodiment, the connecting strap has slots on both sides, and the neck strap assembly has elastic locking buckles on both sides of the connecting strap, thereby further improving the reliability of the connector.

[0011] In a preferred embodiment, the neckband assembly includes a pull-back spring, one end of which is fixedly connected to the inner end of the connector. The pull-back spring pulls the connector back into the neckband assembly, facilitating user adjustment of the connector's position. The connector is preferably a connecting strap.

[0012] The locking assembly includes a compression spring, a compression top block, and an unlocking button. The two ends of the compression spring abut against the compression top block and the neck hanging assembly, respectively. The compression top block is slidably disposed inside the neck hanging assembly and located on one side of the connector. The unlocking button is exposed on the side wall of the neck hanging assembly and located on the other side of the connector. The unlocking button is integrally formed with the compression top block or is connected by transmission.

[0013] When the user presses the unlock button inward, the unlock button directly pushes the clamping block inward, or the unlock button and the clamping block slide inward simultaneously, causing the clamping block to disengage from the connector. The clamping block no longer presses against the connector, thus unlocking it. The connector can then retract upward into the neck assembly or extend downward outside the neck assembly. The user can push the breast pump assembly upward or pull downward. If no external force pulls the connector, it will be pulled back into the neck assembly by the return spring. When the user releases the unlock button, the clamping spring pushes the clamping block outward, causing the clamping block to slide outward and push out the unlock button, or the clamping block and unlock button slide outward simultaneously. The clamping block presses the connector against the inner wall of the installation channel, thus securing the connector. The connector cannot extend or slide. In summary, by pressing the unlock button, pulling or pushing the breast pump assembly, or automatically pulling the connector with the return spring, the user can adjust the length of the connector and ultimately adjust the position of the breast pump assembly.

[0014] In a preferred embodiment, the neck strap assembly has a receiving channel for accommodating a compression spring and a compression top block. One end of the receiving channel is closed and the other end is open. The compression top block is slidably disposed at the open end of the receiving channel. The two ends of the compression spring abut against the inner wall of the receiving channel and the compression top block, respectively. The structure of this utility model is reasonable and the connecting parts are securely locked.

[0015] In a preferred embodiment, the top of the breast pump assembly is provided with a connecting seat, and the outer end of the connector is connected to the connecting seat, which is made of a soft material. The connecting seat can be made of silicone or other soft materials, thereby facilitating the left and right movement of the breast pump assembly and adjusting its position.

[0016] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are:

[0017] A neck-hook breast pump with an extendable pumping unit is designed to allow users to easily adjust the pumping position according to their body shape, without needing to hold the pumping unit with their hands, making it very convenient to use.

[0018] The above-mentioned breast pumps can be adapted to breastfeeding women of different heights and body types, and are compatible with different models of breast pumps on the market, so that two breast pumps can work together without interfering with each other.

[0019] Meanwhile, by placing the air pump inside the breast pump assembly instead of fixing it inside the neck strap assembly, the breast pump assembly can be kept away from the ears when it is working, thus achieving the effects of noise reduction and vibration damping.

[0020] In addition, other advantages of this invention will be set forth in the description which follows, in part will be obvious from the description, or may be learned by practice of this invention. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] Reference Figure 1-13 This invention describes a neck-hook type breast pump according to an embodiment of the present invention.

[0038] Example 1, as Figure 1-8 As shown, it includes a neck-hanging assembly 1 and one or two breast pumping assemblies 2. The breast pumping assembly 2 is equipped with an air pump 22. The breast pumping assembly 2 is connected to the end of the neck-hanging assembly 1 through a length-adjustable connector 3. One end of the connector 3 is fixedly connected to the breast pumping assembly 2, and the other end of the connector 3 is retractably inserted into the end of the neck-hanging assembly 1. The neck-hanging assembly 1 is equipped with a locking assembly 5 for locking the connector 3.

[0039] In this embodiment, the neck hanging assembly 1 is a C-shaped hollow shell, and the connector 3 is telescopically located at the end of the neck hanging assembly 1.

[0040] Furthermore, the locking component 5 can lock the connector 3 through a concave-convex positioning fit or a pressing method. The connector 3 can be a connecting strap or a connecting rope.

[0041] In this embodiment, the neck-hanging assembly 1 is provided with an installation channel 11 for inserting the connector 3. One end of the installation channel 11 is open at the end of the neck-hanging assembly 1, and the cross-section of the installation channel 11 is rectangular or circular.

[0042] In a specific implementation, the breast pump assembly 2 may include a housing 20 and a breast pump cover 21 disposed on the housing 20. The housing 20 contains an air pump 22, a suction bowl 23, a milk collection chamber 24, a battery 26, a display screen 29, a milk outlet 27, a sealing plug 28, control buttons 211, a three-way tube 215, a retaining ring 213, a milk collection chamber 25, a milk collection silicone pad 212, and a control circuit board 210. The aforementioned components of the breast pump assembly 2 and their connections are all existing technology and will not be described in detail here.

[0043] In this embodiment, the neckband assembly 1 is provided with a pull-back coil spring 51, one end of which is fixedly connected to the inner end of the connector 3.

[0044] The locking component 5 includes a compression spring 52, a compression top block 53, and an unlocking button 54. The two ends of the compression spring 52 abut against the compression top block 53 and the neck hanging component 1, respectively. The compression top block 53 is slidably disposed inside the neck hanging component 1 and is located on one side of the connector 3. The unlocking button 54 is exposed on the side wall of the neck hanging component 1 and is located on the other side of the connector 3. The unlocking button 54 is integrally formed with the compression top block 53 or is connected by transmission.

[0045] The neckband assembly 1 has a receiving channel 55 that accommodates a compression spring 52 and a compression top block 53. One end of the receiving channel 55 is closed and the other end is open. The compression top block 53 is slidably disposed at the open end of the receiving channel 55. The two ends of the compression spring 52 abut against the inner wall of the receiving channel 55 and the compression top block 53, respectively.

[0046] Furthermore, the top of the breast pump assembly 2 is provided with a connector 214, and the outer end of the connector 3 is connected to the connector 214. The connector 214 is made of a soft material. The connector 214 is preferably made of silicone.

[0047] The position adjustment principle of the breast pumping component in Embodiment 1 of this utility model is as follows:

[0048] When the user presses the unlock button 54 inward, the unlock button 54 directly presses the clamping block 53 inward, or the unlock button 54 and the clamping block 53 slide inward simultaneously, causing the clamping block 53 to leave the connector 3 and no longer clamp the connector 3, thereby unlocking the connector 3. The connector 3 can retract upward into the neck hanging assembly 1 or extend downward out of the neck hanging assembly 1. The user can push upward or pull downward on the breast pumping assembly 2 to adjust the position of the breast pumping assembly 2. If there is no external pulling force to pull the connector 3, the connector 3 will be pulled back into the neck hanging assembly 1 by the pull-back spring 51. When the user releases the unlock button 54, the compression spring 525 pushes the compression block 53 outward, and the compression block 53 slides outward and pushes out the unlock button 54. Alternatively, the compression block 53 and the unlock button 54 slide outward simultaneously. The compression block 53 presses the connector 3 against the inner wall of the installation channel 11, thereby pressing the connector 3. The connector 3 cannot extend or slide. In summary, the user can adjust the length of the connector 3 by pressing the unlock button 54, pulling or pushing the milk pumping component 2, or automatically pulling the connector 3 by the pull-back spring 51, thereby adjusting the position of the milk pumping component 2.

[0049] In practice, the connector 3 uses a connecting belt, which has a large contact area with the pressing block 53, thus increasing friction.

[0050] The working principle of the above-mentioned neck-hook breast pump is as follows:

[0051] In the breast pump assembly 2, the air pump 22 operates in both an intake and a release state. When the breast pump assembly 2 begins pumping, the air pump 22 is in the intake state, and the suction bowl 23 deforms to create negative pressure in the milk collection chamber 24, drawing in milk. In the release state, the suction bowl 23 springs back to its original position, squeezing the breast milk in the milk collection chamber 24 into the milk collection chamber 25 until the milk collection chamber 25 is full. The inlet of the milk collection chamber 25 is equipped with a milk-collecting silicone sealant to prevent backflow, meaning that breast milk can only enter the milk collection chamber 25 from the milk collection chamber 24 and cannot flow back from the milk collection chamber 25 to the milk collection chamber 24. The air pump 22 continuously performs an intake-exhaustion cycle, similar to the sucking action of an infant, with breast milk continuously flowing from the breast into the milk collection chamber 24 and finally being collected in the milk collection chamber 25. The milk outlet 27 is connected to the milk collection chamber 25. A sealing plug 28 is provided at the milk outlet 27. After the milk pumping action is completed, the sealing plug 28 can be opened to pour the breast milk in the milk collection chamber 25 into a bottle or other container through the milk outlet 27.

[0052] Example 2, as Figure 9-13 As shown, the implementation method of Embodiment 2 is similar to that of Embodiment 1. The connector 3 also uses a connecting strip. The only difference is that multiple slots 31 are provided at intervals along the length direction of the connecting strip, and the locking component 5 is an elastic locking buckle 56. The slots 31 and the elastic locking buckle 56 are positioned and matched in a concave-convex manner.

[0053] The buckle 57 is spherical, and the two adjacent slots 31 are connected by an arc transition structure. The first end of the elastic locking buckle 56 is connected to the neck hanging assembly 1 and is located on one side of the connector 3. The second end of the elastic locking buckle 56 is provided with a buckle 57, which is positioned and engaged with the slot 31.

[0054] More specifically, the first end of the elastic locking buckle 56 is connected to the neck hanging assembly 1 and is located on one side of the connector 3. The second end of the elastic locking buckle 56 is provided with a buckle 57, which is engaged with the groove 31 for positioning.

[0055] Furthermore, the connecting belt has slots 31 on both sides, and the neck strap assembly 1 has elastic locking buckles 56 on both sides of the connecting belt.

[0056] In this embodiment, when the user wants to adjust the position of the breast pump component 2, the user only needs to push the breast pump component 2 upward or pull it downward. The connector 3 retracts upward into the neck hanging component 1 or extends downward into the neck hanging component 1. The slot 31 disengages from the buckle 57. The multiple slots 31 on the connector 3 slide over the buckle 57 until the user stops pushing or pulling the breast pump component 2, so that the breast pump component 2 is in the position that the user wants to adjust. The new slot 31 engages with the buckle 57, and the connector 3 is locked, thereby realizing the adjustment of the position of the breast pump component 2.

[0057] Other components and operations of the neck-hanging breast pump according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
