Description

Technical Field

[0001] This utility model relates to the medical field, specifically a portable breastfeeding device. Background Technology

[0002] Breast milk is the most natural and safe food for infants. It contains the nutrients and antibodies that infants need, which can improve newborns' resistance and immunity and promote their growth.

[0003] Some mothers produce a lot of breast milk, while their babies have limited appetites, often resulting in spitting up. Some mothers use breast pumps to express the milk and refrigerate or freeze it for later use, then warm it in a bottle and feed it to their newborns when needed.

[0004] The above operations not only require hot water or a special bottle warmer, which is cumbersome and inconvenient, but also pose a risk of external infection during the transfer to the bottle, making each feeding of a newborn time-consuming and laborious.

[0005] Therefore, a special device is needed that can easily collect, heat up, and feed the food in order to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a portable breast milk feeder that integrates collection, refrigeration, heating and feeding, while meeting multiple feeding needs and avoiding cumbersome transfer operations, preventing external contamination, increasing the hygiene of breast milk, and ensuring the healthy growth of newborns.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A portable breast milk feeder includes a storage cylinder, a collection cover, a nipple, a collection structure, and a temperature control structure. The collection cover and the nipple are detachably connected to the storage cylinder. The collection structure includes a negative pressure plug, a control button, a locking element, and a linkage assembly. The control button is movably located at the end of the storage cylinder away from the collection cover. The negative pressure plug is movably located inside the storage cylinder. The linkage assembly is located between the control button and the negative pressure plug. The locking element is located on the control button to restrict its movement. A sealing element is movably located between the storage cylinder and the collection cover. The control button is connected to the sealing element through a control assembly. After breast milk is collected into the storage cylinder, the control button drives the sealing element to seal the cylinder. The temperature control structure is located on the outer wall of the storage cylinder to maintain or increase the temperature inside the storage cylinder.

[0009] Compared with existing technologies, the portable breastfeeding device using the above-mentioned technical solution has the following beneficial effects:

[0010] I. This portable breastfeeding device utilizes a combination of control knobs, a negative pressure plug, and linkage components. Combined with the use of a collection cover and the mother's nipple, it allows for the negative pressure collection of breast milk into a storage container. Through the cooperation of locking components, control components, and sealing components, the negative pressure plug is locked while the storage container is simultaneously sealed. In this sealed state, it can be used with existing capped nipples, allowing the collection cover to be replaced with a capped nipple for refrigerated storage. This effectively reduces the probability of external contamination of the breast milk, ensuring its cleanliness and hygiene. Furthermore, the locking and sealing operations are performed simultaneously, making it portable and efficient, requiring no additional or separate steps; mothers can use it directly themselves.

[0011] Second, when using it later, the storage tube, combined with the nipple structure, can be used directly for feeding the baby with the bottle, eliminating the need for cumbersome transfer operations and avoiding a series of hygiene problems caused by improper transfer.

[0012] Third, the constant temperature structure can effectively maintain the low temperature inside the storage container. For home use, when taking other items from the refrigerator door, it can effectively reduce the risk of breast milk spoiling due to temperature changes. Furthermore, it can be heated before subsequent feeding to bring the breast milk to a temperature that meets the feeding requirements, avoiding the cumbersome operation of additional hot water or bottle warmers.

[0013] Preferably, the linkage assembly includes a linkage rod and a rotating rod. The end of the storage cylinder with the control button is a fixed base. The rotating rod is rotatably disposed within the fixed base and connected to the control button. A groove is provided between the fixed base and the storage cylinder for the linkage rod to move. The linkage rod passes through the groove and connects to the negative pressure plug. The linkage rod and the rotating rod are engaged. Rotating the control button causes the linkage rod to move. By utilizing the engagement relationship between the rotating rod and the linkage rod, rotating the control button causes the linkage rod and the negative pressure plug to move, thereby achieving negative pressure suction of breast milk. Mothers only need to apply wrist force when using this device; no large movements are required. It is portable, efficient, and easy to use.

[0014] Preferably, the groove area of ​​the rod is much smaller than the coverage area of ​​the negative pressure plug. Upon completion of suction, the negative pressure plug seals the space between the breast milk and the rod groove, reducing the risk of breast milk leakage and facilitating subsequent feeding operations, thereby improving breast milk utilization.

[0015] Preferably, the locking element comprises a shaped block and a shaped groove. The shaped block is disposed on the rotating rod, and the shaped groove is disposed inside the fixed base. Pressing the control button causes the shaped block to enter the shaped groove. A damping layer is also provided between the control button and the fixed base. Through the cooperation of the shaped block and the shaped groove, the rotation state of the rotating rod is restricted, thereby restricting the movement of the control button, the linkage rod, and the negative pressure, and realizing its locking function. In addition, with the deceleration and limiting effect of the damping layer, excessive operation amplitude can be avoided when rotating to suck breast milk. When the control button is locked and not subjected to external force, the locked state can be effectively restricted and maintained. Furthermore, the damping layer can effectively seal the fixed base, preventing external forces from entering the rod groove through the edge of the control button.

[0016] Preferably, the control component includes a movable rod and a locking button. The movable rod is movably located on the side wall of the storage cylinder where the control button is located, and one end of the movable rod is connected to the sealing component. The portion of the rotating rod near the control button is a relatively thin connecting strip, and the other end of the movable rod is movably sleeved on the connecting strip. The locking button is movably located on the side wall of the storage cylinder and is connected to the movable rod. Pressing the control button or the locking button causes the sealing component to block the passage between the storage cylinder and the collection cover. When the control button is moved towards the groove to lock or the locking button is pressed, the movable rod and the sealing component will be displaced by the pushing force of the control button to achieve the sealing purpose. When the control button is pulled out to unlock, due to the thickness relationship between the connecting strip and the rotating rod body, the movable rod and the sealing component will be displaced by force to achieve the purpose of opening the passage. The locking structure and the operation of opening and closing the passage can cooperate synchronously and smoothly, which is easy to operate and can avoid the risk of forgetting to lock or seal.

[0017] Preferably, the storage cylinder has a countersunk groove on its side wall that matches the locking button. The locking button is highlighted with a color. When the lever is not locked, the outer surface of the locking button does not extend beyond the plane of the countersunk groove opening. The collection cover and nipple can both be threaded onto the storage cylinder, and the nipple is secured with a cap. Before collecting breast milk or feeding, the feedback on the access status is intuitive and clear. Users can determine whether the access is active by looking at the prominent outer side of the locking button.

[0018] Preferably, the temperature-controlled structure is a temperature-controlled layer that surrounds the outer wall of the storage cylinder. This temperature-controlled layer can maintain a low-temperature environment for storing breast milk for a certain period, preventing it from being affected by changes in external temperature and effectively ensuring the safety of the breast milk.

[0019] Preferably, the constant temperature structure further includes a heating layer and a temperature control device. The heating layer is arranged around the outer wall of the constant temperature layer, and a heating patch is provided inside the heating layer. The temperature control device is located at the end of the storage cylinder away from the collection cover, and the temperature control device is electrically connected to the heating patch. Using the temperature control device and the surrounding heating layer, heat is evenly and gradually conducted to the breast milk through the constant temperature layer. Furthermore, due to the connection between the storage cylinder body and the temperature control device, it can be easily shaken by hand to increase the heating and temperature control effect. In addition, in cases where the newborn is uncooperative or feeding is interrupted, temporary warming can be provided, and feeding can resume afterwards, avoiding the problem of breast milk losing temperature and being wasted when comforting the newborn or handling other matters.

[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] like Figures 1 to 7 The portable breastfeeding device shown includes a storage cylinder 1, a collection cover 2, a nipple 3, a collection structure 4, and a temperature control structure.

[0030] The collection cover 2 and the nipple 3 can be detachably connected to the storage cylinder 1, such as through a plug-in or threaded connection structure. In this embodiment, in order to ensure the connection stability and sealing during use, the collection cover 2 and the nipple 3 can be threaded to the storage cylinder 1, and a cap 30 is fastened to the nipple 3.

[0031] The collection structure 4 includes a negative pressure plug 40, a control button 41, a locking member 5, and a linkage assembly 6. The control button 41 is movably located at the end of the storage cylinder 1 away from the collection cover 2. The negative pressure plug 40 is movably located in the storage cylinder 1. The linkage assembly 6 is located between the control button 41 and the negative pressure plug 40. The locking member 5 is located on the control button 41 to limit the movement of the control button 41.

[0032] The linkage assembly 6 includes a linkage rod 60 and a rotating rod 61.

[0033] The storage cylinder 1 has a control knob 41 at one end, which is a fixed base 10. The rotating rod 61 is rotatably disposed in the fixed base 10 and connected to the control knob 41. A rod groove 11 is provided between the fixed base 10 and the storage cylinder 1 to allow the linkage rod 60 to move. The linkage rod 60 passes through the rod groove 11 and is connected to the negative pressure plug 40. The linkage rod 60 is engaged with the rotating rod 61. Rotating the control knob 41 causes the linkage rod 60 to move.

[0034] To reduce the risk of breast milk leaking from the groove 11, the groove area of ​​the groove 11 is much smaller than the coverage area of ​​the negative pressure plug 40, meaning that the negative pressure plug 40 can cover the groove 11 after suctioning.

[0035] A sealing element 7 is movably provided between the storage cylinder 1 and the collection cover 2. The control button 41 is connected to the sealing element 7 through the control component. After the breast milk is collected into the storage cylinder 1, the sealing element 7 is sealed by controlling the control button 41.

[0036] The locking element 5 consists of a shaped block 50 and a shaped groove 51. The shaped block 50 is located on the rotating rod 61, and the shaped groove 51 is located inside the fixed base 10. Pressing the control button 41 causes the shaped block 50 to enter the shaped groove 51. A damping layer 52 is also provided between the control button 41 and the fixed base 10.

[0037] The irregular block 50 has a polygonal and non-circular structure. When the irregular block 50 is inserted into the irregular groove 51, it can restrict the rotation of the rotating rod 61 and the control button 41.

[0038] The control assembly includes a movable lever 80 and a locking button 81. The movable lever 80 is movably located on the side wall of the storage cylinder 1 where the control button 41 is located, and one end of the movable lever 80 is connected to the sealing member 7. The part of the rotating rod 61 near the control button 41 is a relatively thin connecting strip 62, and the other end of the movable lever 80 is movably sleeved on the connecting strip 62. The locking button 81 is movably located on the side wall of the storage cylinder 1 and is connected to the movable lever 80. Pressing the control button 41 or the locking button 81 will cause the sealing member 7 to block the passage between the storage cylinder 1 and the collection cover 2.

[0039] In addition, the surface of the control button 41 is provided with a raised ring 42 for easy removal.

[0040] The storage cylinder 1 has a countersunk groove 12 on its side wall that is adapted to the locking button 81. The surface of the locking button 81 is marked with a color (such as red or orange). When the rotating rod 61 is not locked, the outer surface of the locking button 81 does not extend beyond the plane of the opening of the countersunk groove 12.

[0041] A constant temperature structure is installed on the outer wall of the storage cylinder 1 to maintain or increase the temperature inside the storage cylinder 1.

[0042] The temperature-controlled structure is a temperature-controlled layer 9 made of insulation cotton or foam cotton, which surrounds the outer wall of the storage cylinder 1.

[0043] The constant temperature structure of this case also includes a heating layer 90 and a temperature control device 91. The heating layer 90 is arranged around the outer wall of the constant temperature layer 9, and a heating patch is provided inside the heating layer 90. The temperature control device 91 is located at the end of the storage cylinder 1 away from the collection cover 2 (i.e., the position of the fixing seat 10), and the temperature control device 91 is connected to the heating patch circuit.

[0044] The temperature control device 91 can refer to the temperature control structure of existing micro intelligent temperature control devices (such as electric hot water bags and hand warmers), and is equipped with a corresponding power interface for pre-charging.

[0045] The constant temperature layer 9 and the heating layer are provided with a visible part 92 for exposing the countersunk groove 12. The visible part 92 can be an open structure or a transparent setting of the constant temperature layer 9 and the heating layer at the corresponding position.

[0046] During use, first connect the collection cover 2 to the storage cylinder 1 via thread, place the collection cover 2 at the nipple, and turn the control knob 41, as shown. Figure 5 As shown, when the control button 41 drives the rotating rod 61 to rotate, due to the meshing relationship between the rotating rod 61 and the connecting rod 60, Figure 4The negative pressure plug 40 will gradually move towards the fixed seat 10, drawing the breast milk into the storage cylinder 1. After the breast milk is drawn out, the control knob 41 can be slightly rotated to make it pressable (the state corresponding to the irregular block 50 and the irregular groove). Since the end of the movable rod 80 and the connecting strip 62 are in a relatively independent state, pressing the control knob 41 allows the rotating rod 61 to move towards the irregular groove, causing the irregular block 50 to embed into the irregular groove, restricting the rotation of the control knob 41. This restricts the displacement of the connecting rod 60 and the negative pressure plug 40, locking the position of the negative pressure plug 40. Simultaneously, without external force, the damping layer 52 will stably restrict the current state of the control knob 41.

[0047] Additionally, when the control button 41 is pressed, it pushes the movable lever 80 and the sealing member 7 to move, thus blocking the passage between the collection cover 2 and the storage cylinder 1. At this time, the collection cover 2 can be rotated and unscrewed, the cap 30 can be fastened to the nipple 3, and the nipple 3 can be threaded onto the storage cylinder 1. It can then be placed in a refrigerator for refrigeration. With the help of the temperature-regulating layer 9, the breast milk in the storage cylinder 1 can be kept at a low temperature for a period of time when the refrigerator is opened and closed or when it is temporarily removed.

[0048] To feed breast milk to an infant, the temperature control device 91 can be used to intelligently raise the temperature. The heat from the heating layer will gradually warm the breast milk in the storage cylinder 1 through the constant temperature layer 9. The temperature control device 91 has a preset intelligent temperature control program based on the material thickness and thermal conductivity of the constant temperature layer 9 and the storage cylinder 1. Once the temperature feedback from the temperature control device 91 is appropriate, the heating will be paused, and the control button 41 will be pulled outward by the convex ring 42. As the mechanical structure described above works on the opposite principle, since the connecting strip 62 is thinner than the rotating rod 61, when the control button 41 moves outward, the rotating rod 61 will drive the movable rod 80 and the sealing piece 7 to move synchronously, so as to realize the connection between the nipple 3 and the storage cylinder 1, and the irregular block will disengage from the irregular groove. The movable rod 80 will drive the locking button 81 to reset. The user can clearly see the conspicuous outer side of the locking button 81, which is flush with the countersunk groove 12, through the visible part 92, and know that the breast milk can be released through the nipple 3 at this time. Pulling and removing the cap 30 allows the infant to be breastfed.

[0049] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
