Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, specifically to a breast pump with a quick-release mechanism for pressing and releasing a baby bottle. Background Technology

[0002] Currently, few wearable breast pumps on the market use a press-type bottle disassembly mechanism. The more common press-type disassembly method uses a modular structure mounted on the main unit. This structure integrates the retaining ring, button, and fixing plug. The main characteristic of this method is that the bottle-holding structure is a closed ring. This necessitates a bottle cap that engages with the ring. The cap must be installed on the bottle first, and alignment with the markings during assembly is crucial; otherwise, it won't press in. This adds an extra, cumbersome disassembly and assembly step, and the inconvenience of cleaning and sterilizing an additional component. Furthermore, the clips securing the cap to the bottle are typically inside the bottle opening and protrude from the inner surface. This can cause cuts during cleaning, and the clips are prone to breaking after repeated use, leading to poor fit with the cap and the need for replacement. Utility Model Content

[0039] Example 1

[0040] Combined with appendix Figure 1-12 A breast pump with a quick-release mechanism for pressing and releasing a baby bottle includes a base plate 1. A main unit 2 is fixedly mounted on the base plate 1. The base plate 1 and the main unit 2 are fixed together to realize the breast pump's milk pumping function. The base plate 1 is a mounting base. The main unit 2 is abutted against and fixed together with the front and upper sides of the base plate 1. The side of the breast pump that is in contact with the user's chest is the front side.

[0041] The main unit 2 has a groove 3 inside, which is formed by the inward indentation of the front side of the main unit 2. The groove 3 consists of three spaces: the suction pump groove 31 at the top, the connecting groove 33 at the bottom, and the breast pad groove 32 between the suction pump groove 31 and the connecting groove 33. The three grooves are interconnected. The breast pad groove 32 is used to install the breast pad 6. The suction pump groove 31 has an opening at the top, which is used to install the suction pump. The suction pump is used to provide suction to the breast pad 6. The connecting groove 33 is in contact with the base plate 1 and is used to install the milk collection bottle 4. The bottom of the connecting groove 33 is designed with an opening. The bottom opening of the connecting groove 33 is a rectangular opening at the front and a semi-circular opening at the rear end of the rectangular opening.

[0042] The base plate 1 is provided with a connection opening 13, which is set to correspond with the bottom opening of the connection groove 33. The connection opening 13 and the connection groove 33 are used to facilitate the installation of the milk collection bottle 4. The base plate 1 is provided with a contour plate 12 that corresponds to the inner wall of the connection groove 33. The contour plate 12 is set along the edge of the connection opening 13. The contour plate 12 corresponds to and is fixedly connected to the bottom wall of the connection groove 33 to form a complete downward opening groove 3.

[0043] A symmetrical positioning plate 11 is fixed on the base plate 1. The positioning plate 11 is located outside the contour plate 12. The positioning plate 11 has an arc-shaped structure and is symmetrically arranged on the base plate 1. The positioning plate 11 extends from the rear end of the base plate 1 to the front sides of the base plate 1. The two sides of the positioning plate 11 are vertical plates. The vertical plates are perpendicular to the front end face of the main unit 2. The rear end of the vertical plates on both sides is provided with a plate extending towards the rear end of the base plate 1. The extended plates at the rear end of the vertical plates on both sides are close to each other in an arc shape. The rear end of the extended plates on both sides is provided with a gap to form a button opening. The front end of the vertical plate is a bent end. The bent end extends forward from the front end of the vertical plate. The front end of the bent end is a plate that is inclined towards the connecting opening 13 and towards the rear side. The bent end and the vertical plate are designed as an integral unit.

[0044] A fixing opening 35 is provided on the contour plate 12 at the position corresponding to the vertical plate. The fixing opening 35 is used to hold the components of the collection bottle 4 that extend into the connecting groove 33. The inclined part of the bent end extends to the front end of the fixing opening 35 of the contour plate 12.

[0045] There is a gap between the positioning plate 11 and the contour plate 12. The gap between the positioning plate 11 and the contour plate 12 is used to install the quick-release button 5. The quick-release button 5 consists of a push button 51 located at the rear end and buckles 52 located on both sides in front of the push button 51. An elastic connecting arm 53 for fixed connection is provided between the push button 51 and the buckles 52 located on both sides. The elastic connecting arm 53 is an arc-shaped connection structure. The elastic connecting arm 53 extends arc-shaped from the front end face of the push button 51 to the outer end face of the buckle 52. Alternatively, the elastic connecting arm 53 on the outer side of the buckle 52 can be a straight structure. The elastic connecting arm 53 at the front end of the push button 51 extends arc-shaped to the rear end of the elastic connecting arm 53 on the outer side of the buckle 52. Preferably, the elastic connecting arm 53 is a C-shaped or U-shaped structure.

[0046] Multiple reinforcing ribs can be provided on the positioning plate 11 and the elastic connecting arm 53 to enhance their load-bearing capacity and improve their service life.

[0047] The front end of the buckle 52 has a beveled structure, which corresponds to the bent end on the positioning plate 11. The beveled structure of the buckle 52 is inclined towards the inside of the connecting opening 13 and towards the rear end of the buckle 52. The beveled structure of the buckle 52 abuts against the beveled end on the positioning plate 11. When the buckle 52 moves toward the bent end, the buckle 52 will expand outward toward the outside of the connecting opening 13 due to the cooperation between the beveled end and the beveled front end of the buckle 52.

[0048] On the elastic connecting arm 53, the front end of the push button 51 and the outer side of the corresponding buckle 52 position of the elastic connecting arm 53 are both fixedly provided with elastic elements 54. The elastic elements 54 can be any component that can play a rebound role, and the elastic elements 54 are preferably serpentine springs or other forms of elastic elements or springs. The rear end of the contour plate 12 is provided with a locking step 121 corresponding to the elastic element 54 at the front end of the push button 51. The locking step 121 has protrusions on both sides that protrude to the rear end. The locking step 121 is used to install the elastic element 54 corresponding to the push button 51 and prevent the elastic element 54 from moving. The protrusions of the locking step 121 can restrict the elastic element 54 within the locking step 121. When installing the quick-release button 5, the push button 51 is placed at the button opening 14, and the elastic element 54 corresponding to the push button 51 is placed within the locking step 121. The elastic element 54 corresponding to the position of the buckle 52 is installed on the vertical plate. The elastic element 54 at the rear end of the elastic connecting arm 53 is used to push the push button 51 forward after the user presses it. When the user releases the push button 51, the elastic element 54 moves the push button 51 backward, so that the push button 51 returns to its original position. The elastic elements 54 on both sides of the elastic connecting arm 53 are used to move the entire elastic connecting arm 53 forward when the user presses the push button 51. At this time, due to the bend end and the inclined surface on the buckle 52, the buckle 52 expands outward to both sides. When the user releases the push button 51, the elastic elements 54 on both sides of the buckle 52 move the buckle 52 inward, returning it to its original position.

[0049] The inner side of the buckle 52 is provided with an engaging slope 521. The engaging slope 521 is inclined from the outside to the inside in the direction from bottom to top of the buckle 52. The engaging slope 521 is used to cooperate with the milk collection bottle 4, thereby holding the milk collection bottle 4. The fixing opening 35 on the contour plate 12 is used for the buckle 52 to extend into the connecting groove 3, thereby cooperating with the milk collection bottle 4 installed in the connecting groove 3. The engaging slope 521 of the buckle 52 extends completely into the connecting groove 3 through the fixing opening 35.

[0050] A milk collection bottle 4 is installed at the bottom of the base plate 1. The milk collection bottle 4 consists of a bottle mouth 41 and a bottle body 42. The top of the bottle body 42 is a cylindrical bottle mouth 41. The bottle mouth 41 of the milk collection bottle 4 has a fastening position 411 corresponding to the position of the buckle 52. The fastening position 411 of the bottle mouth 41 of the milk collection bottle 4 has a mating inclined surface 4111. The mating inclined surface 4111 abuts against the locking inclined surface 521. The mating inclined surface 4111 slopes from bottom to top and from outside to inside. Through the engagement of the locking inclined surface 521 and the mating inclined surface 4111, when the milk collection bottle 4 is installed with the buckle 52, the buckle 52 of the bottle mouth 41 of the milk collection bottle 4 abuts against the buckle 52. As the milk collection bottle 4 rises, the locking position 411... The engagement ramp 4111 will cause the buckle 52 to expand outward through the engagement ramp 521, so that the buckle 411 passes over the buckle 52 until the bottom surface of the buckle 411 abuts against the top surface of the buckle 52. At this time, because the engagement ramp 4111 and the engagement ramp 521 are misaligned, the top part of the buckle 52 is the innermost part due to the presence of the engagement ramp 521, and the bottom part of the buckle 411 is the outermost part due to the presence of the engagement ramp 4111. After the engagement ramp 4111 and the engagement ramp 521 are misaligned, the buckle 52 will engage the buckle 411 of the bottle mouth 41 of the milk collection bottle 4 with the buckle 52, thereby fixing the milk collection bottle 4.

[0051] The milk collection bottle 4 is installed by aligning the bottle mouth 41 with the buckle 52 and lifting it upwards into the connecting groove 33. At this time, the buckle 411 of the bottle mouth 41 of the milk collection bottle 4 expands outwards through the cooperation of the bevel 4111 and the engaging bevel 521. When the buckle 411 of the milk collection bottle 4 passes the buckle 52, the elastic members 54 on both sides of the buckle 52 push the buckle 52 back to its original shape. At this time, the top surface of the buckle 52 abuts against the bottom surface of the buckle 411, and the milk collection bottle 4 is fixed by the cooperation of the buckle 52 and the buckle 411. The buckle 411 of the bottle mouth 41 of the milk collection bottle 4 can be a connecting ear that extends to both sides and corresponds to the position of the buckle 52, or an outwardly expanding ring directly provided on the bottle mouth 41. In other embodiments, the buckle 411 can be fixedly installed on the bottle mouth 41 in a detachable form. The milk collection bottle 4 has a buckle 411 located on the outside of the bottle opening 41, while there is no protruding structure on the inside of the bottle opening 41, so it will not cause inconvenience when cleaning the milk collection bottle 4.

[0052] The body 42 of the milk collection bottle 4 is located on the lower side of the base plate 1, with only the bottle mouth 41 of the milk collection bottle 4 located in the connecting opening 13. It extends into the connecting groove 3 through the connecting opening 13 and engages with the buckle 52 to fix the milk collection bottle 4. When it is necessary to remove the milk collection bottle 4, it is only necessary to press the push button 51. Due to the engagement of its bent end and the inclined surface on the buckle 52, the buckle 52 will expand outward to both sides when it moves forward. At this time, since the top surface of the buckle 52 no longer abuts against the bottom surface of the buckle 411, the buckle 52 no longer limits the buckle position 411 of the bottle mouth 41, and the user can pull out the milk collection bottle 4.

[0053] The inner walls of the contour plate 12 and the connecting groove 33 are respectively provided with limiting ribs 34 on the front side of the fixed opening 35. The limiting ribs 34 are used to prevent the milk collection bottle 4 from being pulled out from the opening in front of the connecting groove 3 or the connecting opening 13, thereby fixing the milk collection bottle 4 on the rear side of the connecting groove 3 or the connecting opening 13.

[0054] The top of the suction pump slot 31 is provided with a suction pump mounting hole 311 for installing a suction pump. A suction pump mounting shell 312 is fixed inside the suction pump mounting hole 311. The suction pump mounting shell 312 can be installed in the position of the suction pump mounting hole 311 by means of snap-fit ​​or other fixing methods. The edge of the suction pump mounting shell 312 is fixed to the suction pump mounting hole 311. The suction pump is fixed inside the suction pump mounting shell 312. The suction pump can be directly fixed in the suction pump mounting hole 311 by means of snap-fit ​​or other matching methods. The suction pump is used to provide negative pressure to complete the milk suction action.

[0055] A breast pad 6 is installed in the breast pad groove 32. The breast pad 6 is inserted into the breast pad groove 32. The two side walls of the breast pad groove 32 are provided with fixing ribs 321 arranged from front to back along the inner wall of the breast pad groove 32. The fixing ribs 321 are strip-shaped structures protruding into the breast pad groove 32. The fixing ribs 321 are used to make an interference fit with the breast pad 6. Since the breast pad 6 is made of non-toxic plastic material, when the breast pad 6 is installed in the breast pad groove 32, the breast pad 6 abuts against the fixing ribs 321. The breast pad 6 is squeezed by the fixing ribs 321 and fixed in the breast pad groove 32 through slight elastic deformation. The rear end of the breast pad groove 32 is also provided with a connecting hole 322. The rear end of the breast pad 6 is provided with a positioning pin for cooperating with the connecting hole 322. The positioning pin is inserted into the connecting hole 322. By inserting the positioning pin into the connecting hole 322, it can be further ensured that the breast pad 6 will not move. At the same time, the cooperation between the connecting hole 322 and the positioning pin can also help to install the breast pad 6 in the correct position. It can also help to fix the fixing rib 321 to the breast pad 6, and prevent the fixing rib 321 from loosening due to the movement of the breast pad 6.

[0056] A through hole is provided between the suction pump mounting housing 312 and the breast pad 6. By inserting the suction end of the suction pump into the through hole of the breast pad 6, a negative pressure is generated inside the breast pad 6, thereby enabling the breast pad 6 to suck out milk.

[0057] The end of the nursing pad 6 is the milk outlet 61, which faces the mouth 41 of the milk collection bottle 4. The milk outlet 61 has a double-layered ring, with a collector 62 installed between the inner and outer rings. The collector 62 is fitted outside the inner ring. When in use, the milk collection bottle 4 is snapped upwards onto the buckle 52. At this time, the mouth 41 of the milk collection bottle 4 is fitted outside the milk outlet 61, and the collector 62 is directly inserted into the milk collection bottle 4. When pumping, the milk flows through the milk outlet 61 and the collector 62 to the milk collection bottle 4.

[0058] A sealing ring 63 can be installed between the outer ring of the milk outlet 61 and the bottle mouth 41 of the milk collection bottle 4 to prevent milk overflow. The sealing ring 63 can be pre-fitted onto the outside of the milk outlet 61 or the collector 62. After the bottle mouth 41 of the milk collection bottle 4 is fitted onto the outside of the milk outlet 61 or the collector 62, the sealing ring 63 is directly positioned between the milk outlet 61 and the bottle mouth 41 of the milk collection bottle 4 to provide a seal.

[0059] A housing 7 can be installed on the main unit 2, forming a complete structure with the milk collection bottle 4. This improves the user experience and enhances the aesthetics of the breast pump. A switch for controlling the suction pump can be located on the side of the housing 7. The intermittent switching of the suction pump completes the pumping process. Milk enters the nursing pad 6 and is collected in the milk collection bottle 4 through the outlet 61. A charging port for charging the suction pump can also be located on the side of the housing. The suction pump includes the main unit and related accessories. The suction pump provides sufficient negative pressure.

[0060] The connecting groove 33 and the connecting opening 13 are used to facilitate the installation of the breast pad 6. When in use, the user first connects the breast pad 6 to the suction end of the suction pump, then installs the breast pad 6 into the breast pad groove 32, and finally inserts the milk collection bottle 4, thereby connecting the breast pad 6 and the milk collection bottle 4.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
