Description

Technical Field

[0001] This utility model belongs to the field of maternal and infant products technology, specifically relating to a combination structure of a breast pump and its accessories. Background Technology

[0002] Breast pumps are divided into manual and electric breast pumps. Manual breast pumps are time-consuming, laborious, and have low milk extraction efficiency, so they have been gradually replaced by electric breast pumps. Currently, most electric breast pumps are handheld or wearable. Handheld electric breast pumps require users to hold the pump with their hands, which cannot free their hands and affects the user experience. Wearable electric breast pumps require the main unit to be placed, which affects the user's normal movement. In addition, due to the increased weight and size of wearable electric breast pumps, they are prone to shifting and leaking air during movement, which restricts normal movement during milk extraction and affects the user experience.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a breast pump main unit and a breast pump [202322815743.1], which includes an air pump, a battery, a valve body, and a neck-hanging structure. The neck-hanging structure has a first enclosing shell and a second enclosing shell at both ends. At least one of the air pump and at least one of the batteries has a portion disposed within the first enclosing shell and another portion disposed within the second enclosing shell. At least one of the first and second enclosing shells has an air vent communicating with the air pump.

[0004] The above solution addresses the issues of existing breast pumps not freeing up hands and being inconvenient to carry to some extent. However, the solution still has many shortcomings. For example, the breast pump main unit and the neck-hanging structure are integrated into one assembly. If either side of the breast pump main unit is damaged, it cannot be replaced, and the entire machine must be purchased, increasing the user's cost. Furthermore, the breast pump can only be used in the neck-hanging manner, which limits its applicability. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a matching structure for a breast pump and its accessories.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a breast pump and accessory combination structure, including a breast pump main unit, wherein the breast pump main unit cooperates with a magnetic suction accessory or a hanging accessory, the magnetic suction accessory and the breast pump main unit are connected by a concave-convex limiting magnetic connection structure, and the hanging accessory includes a curved hanging part, and both ends of the hanging part are respectively provided with a main unit mounting sleeve, the main unit mounting sleeve is made of elastic material, the main unit mounting sleeve has a main unit mounting cavity inside, and one side of the main unit mounting sleeve is provided with a main unit mounting inlet communicating with the main unit mounting cavity. The main unit mounting inlet facilitates the placement of the breast pump main unit in the main unit mounting cavity, and the elastic main unit mounting sleeve can wrap and clamp the breast pump main unit to ensure the installation stability of the breast pump main unit in the main unit mounting sleeve.

[0007] In the above-mentioned combination structure of breast pump and accessories, the magnetic accessory is in the shape of a flat box, and the size of the magnetic accessory is smaller than the size of the breast pump main unit.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, a breast pump and accessory assembly structure includes a breast pump main unit 1, which cooperates with a magnetic attachment 2 or a hanging attachment 3. This allows for the detachment and removal of the breast pump main unit 1, and users can select different mounting accessories for the breast pump main unit 1 according to their usage, improving the user experience. The magnetic attachment 2 and the breast pump main unit 1 are connected by a concave-convex limiting magnetic connection structure 4. This structure facilitates the magnetic attachment 2 and the breast pump main unit 1 during installation, ensuring a secure and effective installation. The suspension accessory 3 includes a curved suspension part 31, and the two ends of the suspension part 31 are respectively provided with main unit mounting sleeves 32. The main unit mounting sleeves 32 are made of elastic material. The main unit mounting sleeves 32 have a main unit mounting cavity 33 inside, and a main unit mounting inlet 34 connected to the main unit mounting cavity 33 is provided on one side of the main unit mounting sleeves 32. The main unit mounting inlet 34 makes it easy to place the breast pump main unit 1 into the main unit mounting cavity 33. The elastic main unit mounting sleeves 32 can wrap and clamp the breast pump main unit 1 to ensure the installation stability of the breast pump main unit 1 in the main unit mounting sleeves 32.

[0031] Specifically, the magnetic attachment 2 is in the shape of a flat box, and its size is smaller than that of the breast pump main unit 1. This makes it easy for the magnetic attachment 2 to be magnetically attached to clothing, reducing its impact on the user and allowing the user to move around more easily during breast pumping.

[0032] The concave-convex limiting magnetic connection structure 4 includes a concave-convex limiting component 41 and a magnetic connection component 42 disposed between the magnetic accessory 2 and the breast pump main unit 1. The concave-convex limiting component 41 facilitates the positioning and installation between the magnetic accessory 2 and the breast pump main unit 1, and the magnetic connection component 42 facilitates the magnetic connection between the magnetic accessory 2 and the breast pump main unit 1 after the magnetic connection component 42 is positioned and installed, thus ensuring the connection effect between the magnetic accessory 2 and the breast pump main unit 1 and improving the connection efficiency.

[0033] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the concave-convex limiting component 41 includes a first magnetic suction surface 411 disposed on one side of the magnetic suction accessory 2. The first magnetic suction surface 411 abuts against a second magnetic suction surface 412 on one side of the breast pump host 1. The first magnetic suction surface 411 is provided with an inwardly recessed magnetic suction surface concave surface 413, and the second magnetic suction surface 412 is provided with an outwardly protruding magnetic suction surface convex surface 414. The magnetic suction surface concave surface 413 and the magnetic suction surface convex surface 414 are engaged with each other. The magnetic suction surface concave surface 413 and the magnetic suction surface convex surface 414 can ensure that the first magnetic suction surface 411 and the second magnetic suction surface 412 can be quickly positioned and abutted, thereby improving the installation efficiency of the magnetic suction accessory 2 and the breast pump host 1.

[0034] Furthermore, the magnetic connection assembly 42 includes a first magnet 421 installed inside the magnetic accessory 2 and near the concave side 413 of the magnetic surface, and a second magnet 422 provided inside the breast pump main unit 1 near the convex side 414 of the magnetic surface. The first magnet 421 and the second magnet 422 correspond to each other and are magnetically connected. The first magnet 421 and the second magnet 422 can ensure the magnetic attraction effect after the magnetic accessory 2 and the breast pump main unit 1 come into contact with each other.

[0035] The magnetic accessory 2 includes a flat accessory box 21. The flat shape can effectively reduce the impact on the user. One side of the accessory box 21 is open 211 and closed by the accessory cover 22. The magnetic concave surface 413 is located on the side of the accessory box 21 away from the accessory cover 22. The open 211 makes it easy to place the first magnet 421, and the accessory cover 22 can protect the first magnet 421 and improve the service life of the first magnet 421.

[0036] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the first magnet 421 is installed in the mounting groove 212 at the bottom of the accessory box 21, and the inner side of the accessory cover 22 is provided with a positioning ring 221 that abuts against the first magnet 421.

The reinforcing ribs 222 can improve the overall structural strength of the positioning ring 221 and the accessory cover 22, thereby increasing its service life.

[0037] Both the suspension part 31 and the main unit mounting sleeve 32 are made of silicone material. The main unit mounting sleeve 32 is symmetrically arranged at both ends of the suspension part 31. The silicone material facilitates contact with the skin, improving the user experience. Furthermore, the main unit mounting sleeve 32 can simultaneously install two breast pump main units, ensuring milk pumping efficiency.

[0038] Specifically, the mounting sleeve 32 has a notch 321 on one side that communicates with the mounting inlet 34. The notch 321 corresponds to the button 11 on one side of the breast pump main unit 1. The mounting sleeve 32 also has several slots 322 on the outside. The slots 322 correspond to the charging port 12 and interface 13 on the outer periphery of the breast pump main unit 1. The notch 321 facilitates the placement of the button 11, making it easy for the user to control the breast pump main unit 1. The slots 322 facilitate the user to charge the breast pump main unit 12 and connect it to the breast pump device, making it easier for the user to control the breast pump main unit 1 and improving the user experience.

[0039] Combination Figure 4 As shown, the suspension part 31 and the main unit mounting sleeve 32 are integrated into one structure. The inner side of the middle part of the suspension part 31 is provided with several anti-slip textures 311, and the diameter of the middle part of the suspension part 31 gradually decreases to the diameter of both ends. The anti-slip textures 311 can prevent the suspension part 31 from shifting and ensure the milk pumping effect.

[0040] The principle of this embodiment is that the breast pump main unit 1 can be connected to the breast pump main unit 1 by either magnetic attachment 2 or hanging attachment 3, depending on the usage. When magnetic attachment 2 is used, the concave and convex limiting magnetic connection structure 4 can magnetically connect the magnetic attachment 2 to the breast pump main unit 1, making it easy to magnetically attach the breast pump main unit 1 to clothing. When hanging attachment 3 is used, the breast pump main unit 1 can be movably mounted and dismounted with the hanging attachment 3 through the main unit mounting sleeve 32, improving the applicability of the breast pump main unit 1 and facilitating the replacement and maintenance of the breast pump main unit 1.
