Description

Technical Field

[0001] The invention relates to maternal and infant products, and in particular to a waterproof integrated electric breast pump. Background Art

[0002] A breast pump is a tool used to squeeze out breast milk accumulated in the mammary glands. Currently, the commonly used breast pumps are divided into two types: manual control and electric control. Manually controlled breast pumps cannot guarantee the same strength and speed each time, so the uniformity and stability of milk extraction are poor.

[0003] The electric breast pump includes a vacuum pump to provide power for sucking milk, but most existing electric breast pumps adopt a split design, in which the vacuum pump is separated from the milk suction mechanism. When in use, the vacuum pump is connected to the milk suction mechanism through a straw to work. This type of breast pump is large in size and occupies a large space during storage and transportation. In the existing waterproof integrated electric breast pump, the vacuum pump is arranged in the motor housing, and is detachably connected to the milk suction mechanism through the motor housing. However, since a through hole connected to the milk suction mechanism is provided on the motor housing, the motor housing cannot be cleaned, which may cause bacteria breeding problems, and it is inevitably necessary to touch it during use. Therefore, there is still room for improvement. Summary of the invention

[0040] The milk suction assembly 2 includes a three-way housing 21, which has a lotion inlet 211, a lotion outlet 212, a connection interface 214 for installing the housing 11, and a negative pressure chamber 213 arranged in the three-way housing 21, wherein the lotion inlet 211 is connected to a trumpet-shaped silicone milk cup 23, and the lotion outlet 212 is connected to the milk bottle 3. The negative pressure chamber 213 is in communication with the lotion inlet 211, a leather cup 22 is arranged in the negative pressure chamber 213, and a concave air cavity 221 is formed in the leather cup 22, the air inlet 111 and the exhaust hole 112 are both in communication with the concave air cavity 221, and the leather cup 22 can be made to concave upwards by the operation of the vacuum pump 12 and the solenoid valve 13, so that the lotion is sucked out and injected into the milk bottle 3 connected to the milk outlet.

[0041] Specifically, two concentric annular flanges 1732 extend downward from the bottom of the shell 11, and the opening edge of the leather cup 22 is bent outward and overlapped at the connection interface 214 of the three-way shell 21. Then, the shell 11 and the three-way shell 21 are installed by inserting the leather cup 22 and the connection interface 214 into the two annular flanges 1732.

[0042] Combination Figure 7-10 As shown, the bottom of the housing 11 is provided with an air inlet 111, and a first foolproof column 141 is inserted in the air inlet 111. The first foolproof column 141 moves upward or downward, so that the vacuum pump 12 is connected or disconnected with the inner cavity of the milk suction assembly 2, that is, connected or disconnected with the concave air cavity 221. In this specific embodiment, the bottom of the housing 11 is provided with a vertically extending first hollow cylinder 151, the air inlet 111 is located in the first hollow cylinder 151, the side of the first hollow cylinder 151 is provided with a first vent 1511, and the bottom of the first hollow cylinder 151 is provided with a constricted opening, and the outer side of the first foolproof column 141 is sleeved with at least one first sealing ring 161.

[0043] When the first anti-foolproofing column 141 moves upward, the first sealing ring 161 moves upward with the first anti-foolproofing column 141, and makes the first anti-foolproofing column 141 and the first sealing ring 161 move to above the first vent 1511, so that the air in the milk suction assembly 2 can be sucked into the vacuum pump 12 through the air inlet 111 and the first vent in sequence; when the first anti-foolproofing column 141 moves downward, the lower end of the first anti-foolproofing column 141 abuts against the bottom of the first hollow cylinder 151, and is sealed through the gapless connection between the first sealing ring 161 located below the first vent 1511 and the inner wall of the first hollow cylinder 151.

[0044] The bottom of the housing 11 is also provided with an exhaust hole 112 connected to the inner cavity of the milk suction assembly 2, that is, the exhaust hole 112 connected to the concave air cavity 221, which is used to accelerate the leather cup 22 to recover its deformation. The exhaust hole 112 is located between the two annular convex edges 1732. The exhaust hole 112 is inserted with a second foolproof column 142. The lower end of the second foolproof column 142 passes through the housing 11, and the first foolproof column 141 and the second foolproof column 142 are fixedly connected by a horizontally extending connecting rod 143, so that the first foolproof column 141 and the second foolproof column 142 can move upward or downward synchronously. When the housing 11 is installed on the three-way housing 21, the second foolproof column 142 is lifted up by the three-way housing 21 and the leather cup 22, and drives the first foolproof column 141 to move upward at the same time.

[0045] Specifically, a second hollow cylinder 152 extending vertically is provided at the bottom of the shell 11, the exhaust hole 112 is located in the second hollow cylinder 152, a second vent 1521 is provided on the side of the second hollow cylinder 152, and at least one second sealing ring 162 is sleeved on the outer side of the second anti-foolproof column 142. When the second fool-proofing column 142 moves upward, the second sealing ring 162 moves upward with the second fool-proofing column 142, so that the sealing ring moves to the top of the second vent 1521, and the lower end of the second fool-proofing column 142 is inserted into the second hollow cylinder 152 and blocks the second vent 1521. The air in the shell 11 can enter the inner cavity of the milk suction assembly 2 through the second vent 1521 and the gap between the second fool-proofing column 142 and the second hollow cylinder 152 in sequence; when the second fool-proofing column 142 moves downward, the second sealing ring 162 located below the second vent 1521 and the inner wall of the second hollow cylinder 152 are connected without a gap for sealing.

[0046] A reset member 181 is also provided in the housing 11, and the reset member 181 can move the first anti-foolproof column 141 and the second anti-foolproof column 142 downward, so that the disassembled driving assembly 1 is in a sealed state.

[0047] Specifically, a horizontally extending positioning plate 144 is provided in the housing 11, and a positioning hole 1441 is provided on the positioning plate 144. The upper end of the first foolproofing column 141 or the second foolproofing column 142 is inserted into the positioning hole 1441. The reset member 181 is a compression spring, and the upper end of the reset member 181 abuts against the positioning plate 144, and the lower end of the reset member 181 abuts against the connecting rod 143. In this specific embodiment, the compression spring is sleeved on the second foolproofing column 142, and the upper end of the compression spring abuts against the positioning plate 144, and the lower end of the compression spring abuts against the connecting rod 143. Under the action of the reset member 181, the second foolproofing column 142 extends downward from the housing 11 and is located in the two annular convex edges 1732. When the housing 11 is installed on the three-way housing 21, the second foolproofing column 142 can be pushed up, and then the first foolproofing column 141 can be pushed up.

[0048] The second hollow cylinder 152 has a third hollow cylinder 153 extending outward from the edge of the second vent 1521. Sound-absorbing cotton 1531 is arranged in the third hollow cylinder 153 to reduce the noise generated during exhaust. In this embodiment, the outer side of the vacuum pump 12 is also provided with sound-absorbing cotton 1531 to reduce the noise generated during the operation of the vacuum pump 12.

[0049] A fourth hollow cylinder 154 extending vertically is provided in the shell 11, the bottom of the fourth hollow cylinder 154 is closed, the upper end of the fourth hollow cylinder 154 is connected with the vacuum pump 12 through the air duct 121, and two air vents are provided on the side of the fourth hollow cylinder 154, one of which is connected with the second air vent 1521, and the other is connected with the valve port 1312 of the solenoid valve 13.

[0050] like Fig.11 As shown, the solenoid valve 13 includes an electromagnetic coil (not shown in the figure), a valve core (not shown in the figure) which is actuated by the power on or off of the electromagnetic coil, and a valve body 131 which cooperates with the valve core. The valve body 131 is provided with a side inflation hole 1311 and a valve port 1312 which is arranged opposite to the valve core. The side inflation hole 1311 is arranged at a position where the valve core and the valve port 1312 cooperate. The electromagnetic valve 13 is connected with the fourth hollow cylinder 154 through the valve port 1312. The valve core abuts against or leaves the valve port 1312 as the electromagnetic coil is powered on or off, so that outside air cannot or can enter the housing 11 through the side inflation hole 1311.

[0051] A one-way valve 4 is provided at the lotion outlet 212 of the three-way housing 21, so that the lotion can only enter the milk bottle 3 from the lotion outlet 212. The one-way valve 4 includes a valve body 41 and two valve plates 42 located at the bottom of the valve body 41. The bottoms of the two valve plates 42 fit each other. After the lotion enters the valve body 41, the two valve plates 42 are separated from each other under the action of gravity, so that the lotion enters the bottle body. Specifically, the valve plates 42 are made of suction silicone material. The valve body 41 of the one-way valve 4 is detachably connected to the lotion outlet 212 of the three-way housing 21.

[0052] The working process of the waterproof integrated electric breast pump in this embodiment is as follows:

[0053] The valve body 131 of the solenoid valve 13 extends out, and the vacuum pump 12 sucks the gas in the leather cup 22, causing the leather cup 22 to sag upward and deform. At this time, the pressure in the negative pressure chamber 213 is less than the atmospheric pressure, so that the lotion can be sucked out and injected into the bottle 3; when the vacuum pump 12 is exhausted, the valve body 131 of the solenoid valve 13 retracts, so that part of the gas ejected by the solenoid valve 13 can be discharged from the valve port 1312 and the side inflation hole 1311 into the shell 11.

[0054] Compared with the prior art, the waterproof integrated electric breast pump of the present invention has the advantage that after the shell 11 is removed from the three-way shell 21, under the action of the reset member 181, the first anti-fool column 141 and the second anti-fool column 142 move downward, and the sealing of the shell 11 is achieved through the gapless connection between the sealing ring and the hollow cylinder, so that the shell 11 can be rinsed with water, solving the problem that the surface of the shell 11 cannot be cleaned. After the shell 11 is installed on the three-way shell 21, the three-way shell 21 can lift the second anti-fool column 142, thereby driving the first anti-fool column 141 to lift up, so that the vacuum pump 12 and the solenoid valve 13 can work normally.

[0055] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
