[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] refer to Figure 1-3 A wearable electric breast pump comprises: a main unit 1 having a body 11, a driving pump 12 installed in the body 11, and a negative pressure chamber 13, wherein a mounting chamber 14 is formed inwardly on one side of the body 11, and the negative pressure chamber 13 is located in the mounting chamber 14; a storage bottle 2 is installed at the bottom of the body 11; a tee 3 is located in the mounting chamber 14, and has a first connecting port 31 that is interconnected and connected to the negative pressure chamber 13, a second connecting port 32 that is connected to the storage bottle 2, and a third connecting port 33 that extends outwardly toward the outside of the mounting chamber 14 to form a trumpet shape, and the third connecting port 33 is close to the second connecting port 32; a breast shield 4 is attached to the third connecting port 33, and the outer ring has an extension portion 41 that exceeds the second connecting port 32, and the extension portion 41 is tightly attached to the side wall of the body 11 on the side where the mounting chamber 14 is formed.

[0028] It is understandable that the body 11 is a main structure for installing other components, for example, it can be an integral molding or an assembly of multiple shells, etc., but it is not limited to this. The drive pump 12 is a component that provides suction, which is connected to the negative pressure chamber 13, and then drives the negative pressure chamber 13 to perform negative pressure adsorption. The storage bottle 2 is a component for storing milk, for example, it can be a bottle body or a packaging bag, etc., but it is not limited to this. The three-way piece 3 is a component for connecting the storage bottle 2, the negative pressure chamber 13 and the breast shield 4 to realize the milk suction work, and its connection with the storage bottle 2 and the negative pressure chamber 13 can be, for example, a threaded connection or a snap-on connection, etc., but it is not limited to this. The breast shield 4 is a component that seals and fits the breast, for example, it can be made of silicone, rubber, thermoplastic elastomer, etc., but it is not limited to this.

[0029] Thus, when in use, the breast shield 4 is attached to the breast, and the nipple directly enters the tee 3. At this time, the pump 12 is driven to drive the negative pressure chamber 13 to suck milk, and the milk directly enters the storage bottle 2 through the second connection port 32. The short stroke setting can be worn directly while lying down or reclining, and there is no problem of milk backflow.

[0030] In some embodiments, reference Figure 2-3 The side of the housing 11 defining the mounting cavity 14 is provided with a first arc groove 5 that mates with the trumpet-shaped third connection port 33. Furthermore, the side of the housing 11 defining the mounting cavity 14 is provided with a second arc groove 6 that mates with the extension 41. As will be appreciated, the provision of the first arc groove 5 and the second arc groove 6 respectively provides inwardly compatible mounting for the third connection port 33 and the breast shield 4, thereby enhancing the overall structural compactness and stability.

[0031] In some embodiments, a one-way valve 7 is installed within the second connection port 32 to prevent milk from flowing into the storage bottle 2 in a one-way manner. It is understood that the one-way valve 7, which prevents milk from flowing into the storage bottle 2 in a one-way manner, may be, for example, a duckbill valve, a spring-loaded check valve, or a lift-type check valve, but is not limited thereto. This prevents milk from flowing back from the storage bottle 2 into the tee 3.

[0032] In some embodiments, the negative pressure chamber 13 is provided with corresponding upper and lower sealing grooves 131, and the outer wall of the second connection port 32 is provided with a sealing ring 311 that seals with the sealing groove 131. The shape of the sealing groove 131 is designed to match the outer shape of the second connection port 32. For example, if the outer circle of the second connection port 32 is circular, the sealing groove 131 can be designed as a vertically symmetrical arc, but is not limited to this. The sealing ring 311 is an elastic sealing member, such as rubber or silicone, but is not limited to this. This configuration can enhance the sealing performance of the connection between the tee 3 and the negative pressure chamber 13.

[0033] In some embodiments, limiting protrusions 141 are provided on both side walls of the installation cavity 14 near one end of the negative pressure cavity 13, and limiting holes 312 are provided on both sides of the outer wall of the second connection port 32 to align with the limiting protrusions 141. Here, the limiting protrusions 141 and the limiting holes 312 are aligned with the shaft holes. During installation, the tee 3 is inserted into the installation cavity 14. Installation is complete until the limiting protrusions 141 are embedded in the limiting holes 312.

[0034] Furthermore, positioning grooves 51 are defined on both sides of the first arc groove 5, and an insert 331 is provided on the outer wall of the third connection port 33 to engage with the positioning grooves 51. It is understood that during installation, the tee 3 may deflect, causing the stop protrusion 141 to misalign with the stop hole 312. In this case, the tee 3 needs to be rotated to find the mating position. The coordination between the positioning grooves 51 and the insert 331 allows the tee 3 to be positioned in the deflected direction, allowing the stop protrusion 141 to quickly engage with the stop hole 312, thereby improving installation efficiency.

[0035] In some embodiments, the body 11 further includes a vibration motor 8 mounted therein, which drives the breast shield 4 to perform a vibrating massage. Furthermore, the main unit 1 includes a control panel 9 for controlling the breast pump. One or more vibration motors 9 can be installed. The control panel 9 can control the pump 12 on / off, the vibration motor 9 on / off, and the vibration power of the vibration motor 9.

[0036] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
