Description

Technical Field

[0001] The present invention relates to the technical field of breast pumps, and in particular to a vacuum pump and a breast pump with integrated pump and valve. Background Art

[0002] A breast pump is a device used to help mothers extract breast milk, usually during breastfeeding. These devices help mothers collect breast milk when needed for later feeding or storage. Breast pumps not only help maintain milk supply and resolve breast discomfort during breastfeeding, but also provide more options and flexibility for breastfeeding, allowing mothers to better manage their breastfeeding process while ensuring that their babies are adequately nourished. The vacuum pump in a breast pump is one of the core components, which is responsible for generating negative pressure to simulate the sucking action of a baby and help the mother to discharge milk.

[0003] A vacuum pump with integrated pump and valve usually refers to a vacuum pump device that integrates the pump body and valve control functions. This design aims to improve the system integration, simplify the operation process and optimize the performance. A vacuum pump with integrated pump and valve may adopt a compact integrated design, which closely combines the pump body and the valve control unit, reduces the pipe connection and leakage points, and improves the overall performance and reliability of the system.

[0004] Traditional breast pumps need to be held manually when in use. Since pumping milk takes a certain amount of time, holding the hands will cause hand fatigue and discomfort. When the hands shake, it will be difficult to maintain a constant position and angle of the breast pump, which will affect the efficiency of milk extraction.

[0005] In summary, the prior art lacks a technology for automatically positioning a breast pump instead of holding it by hand. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a vacuum pump and a breast pump with integrated pump and valve.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: a vacuum pump and breast pump with integrated pump and valve, including a vacuum pump body, two suction pipes are plugged into the vacuum pump body, a milk suction cover is plugged into the other end of the suction pipe, a positioning cover is provided on one side of the milk suction cover, a placement seat is connected and fixed to the bottom of the positioning cover, a rotating ring is rotatably connected inside the positioning cover, a fixed frame is connected and fixed to the rotating ring, a transmission mechanism is rotatably connected to the fixed frame, and an auxiliary milk suction mechanism is slidably provided on the fixed frame.

[0008] Preferably, a guide tube is threadedly connected to the milk suction cover, a silicone breast shield is threadedly connected to one end of the guide tube, and a feeding bottle is threadedly connected to the bottom of the guide tube.

[0009] Preferably, the two positioning covers are connected and fixed by an elastic band, a shoulder strap is connected and fixed to the positioning cover, and one end of the shoulder strap is connected and fixed to a Velcro.

[0010] Preferably, the positioning cover is arranged in a conical structure, the inner wall of one end of the positioning cover is adapted to the outer wall of the silicone breast shield, a hollow rubber layer is connected and fixed inside the positioning cover, the hollow rubber layer is filled with water, a plurality of electric heating wires A are installed and fixed on the inner wall of one end of the positioning cover, a heat conducting plate is connected and fixed to the inner wall of the positioning cover located at the electric heating wires A, and the other end of the heat conducting plate extends into the hollow rubber layer.

[0011] Preferably, a plurality of clamping blocks are slidably provided inside the placement seat, a spring is connected and fixed between the clamping blocks and the inner wall of the placement seat, and a plurality of electric heating wires B are installed and fixed on the inner wall of the bottom end of the placement seat.

[0012] Preferably, an annular rack A is fixedly connected to one end of the rotating ring, a driving wheel is meshingly and transmission-engaged on one side of the annular rack A, a motor is fixedly connected to the driving wheel, and the motor is fixedly connected to the inner wall of the positioning cover.

[0013] Preferably, the transmission mechanism comprises a reciprocating screw rod, which is rotatably connected to a fixed frame, one end of which is fixedly connected to a transmission wheel, and the transmission wheel is meshed with an annular rack B fixedly connected to the positioning cover for transmission.

[0014] Preferably, a driving wheel is fixedly connected to one end of the reciprocating screw rod, a driven wheel is meshingly and transmission-equipped with the driving wheel, a transmission rod is fixedly connected to the driven wheel, and the transmission rod is rotatably connected to the fixed frame.

[0015] Preferably, the auxiliary milk suction mechanism includes a moving block, the moving block is threadedly connected to the reciprocating screw, the moving block is rotatably connected with a transmission sleeve, the transmission sleeve is slidably matched with the transmission rod, both ends of the transmission sleeve are connected and fixed with incomplete gears, the moving block is rotatably connected with a worm, one end of the worm is connected and fixed with a bevel gear, the bevel gear is meshed with the incomplete gear, both sides of one end of the worm are meshed and transmitted with worm wheels, the worm wheel is rotatably connected to the moving block, and a breast massage rod is connected and fixed to the worm wheel.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When breast milk needs to be pumped, the positioning shield can be fixed to the breast through the shoulder straps and Velcro, and then the positioning shield can pressurize the silicone breast shield so that the silicone breast shield can be closely attached to the breast. By placing the milk bottle in the placement seat and fixing it through the clamping block, the breast pump can maintain a fixed position and angle during use, and the user does not need to hold it, freeing up both hands, reducing hand fatigue and shaking that cause gaps between the silicone breast shield and the skin, thereby ensuring the efficiency and effect of milk pumping; When pumping breast milk, the water in the hollow rubber layer can be heated to provide a hot compress to the breast, which can help relax the mammary glands and milk ducts and promote the flow of milk. This makes it easier to collect enough milk when using a breast pump, improving efficiency and time utilization. At the same time, the heated placement seat can be set to keep the milk in the bottle warm to avoid the breast milk temperature being too low, thereby ensuring the safety and comfort of feeding the baby. When expressing breast milk, massaging the breasts with a breast massage rod can help promote the flow of milk in the mammary glands and milk ducts, relieve pain and discomfort, and effectively solve the problem of milk accumulation when milk blockage occurs. At the same time, it can improve breast blood circulation, promote the delivery of nutrients and the synthesis of milk, contribute to the health and function of the breasts, and improve the efficiency and comfort of using a breast pump.

DETAILED DESCRIPTION

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] like Figure 1-Figure 8 The vacuum pump and breast pump with integrated pump and valve shown in the figure include a vacuum pump body 1, two suction pipes 2 are plugged into the vacuum pump body 1, a milk suction cover 3 is plugged into the other end of the suction pipe 2, a positioning cover 4 is arranged on one side of the milk suction cover 3, a placement seat 5 is connected and fixed to the bottom of the positioning cover 4, a rotating ring 6 is rotatably connected and arranged in the positioning cover 4, a fixed frame 7 is connected and fixed to the rotating ring 6, a transmission mechanism is rotatably arranged on the fixed frame 7, and an auxiliary milk suction mechanism 8 is slidably arranged on the fixed frame 7. The model of the vacuum pump body 1 is a membrane pump, and its working principle is as follows: the membrane pump changes the volume of the pump chamber through the reciprocating motion of the diaphragm, thereby forming a vacuum. There are one or more diaphragms in the pump chamber, which reduce the pressure in the pump chamber by compressing air or liquid, thereby generating a vacuum. A vacuum layer is arranged in the outer shell of the vacuum pump body 1, so that the vacuum pump body 1 can play a silencing role when in use.
