[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0034] For an anti-loosening breast pump, please refer to [link / reference]. Figure 1 As shown in Figure 4, it includes: a first fuselage 100 and a second fuselage 200, which are separate structures.

[0035] The first body 100 is equipped with an air pump assembly 110, which functions to draw in and release air.

[0036] The second body 200 is configured with a breast cup 210 and a milk collection bin 220. The breast cup 210 can accommodate a breast, and the milk collection bin 220 is used to collect the pumped breast milk.

[0037] As shown in Figure 2 , the breast cup 210 opens outwardly toward the paper surface. Assuming that the user is in a sitting position at this time, the breast cup 210 is pressed against the user's breast vertically outwardly when the breast pump is used;

[0038] As shown in Figure 3 , the breast cup 210 opens downwardly. Assuming that the user is in a supine position at this time, the breast cup 210 is pressed against the user's breast from top to bottom when the breast pump is used;

[0039] As shown in Figure 3 and Figure 4 , the first body 100 is assembled to the second body 200 in a direction in which the breast cup 210 is pressed against the breast;

[0040] As shown in Figure 5 , when in use, the breast pump is located between the breast cup 00 and the breast. As shown in Figure 5 , assuming that the user is in a supine position, the breast cup 210 is tightly attached to the user's breast. After the user wears the breast cup 210, the first body 100 and the second body 200 are squeezed downwardly by the breast cup 00 and pressed against the breast.

[0041] Therefore, the first body 100 and the second body 200 are always in a pressed state to prevent loosening during use of the breast pump. Regardless of whether the user is in a sitting position or a supine position, the first body 100 and the second body 200 are always in a pressed state to prevent loosening, thereby ensuring normal operation of the breast pump.

[0042] It should be noted that the breast cup 00 is not specifically shown in the drawings. The breast cup 00 can be a common breast cup that is usually worn by the user. The breast pump is placed in the cup and is pressed against the user's breast by the elastic force of the breast cup 00.

[0043] Alternatively, the breast cup 00 can be specially designed to be adapted to the breast pump and have a specific position for installing the breast pump.

[0044] In an embodiment, as shown in Figure 3 , the second body 200 is further configured with a milk collection bin 230. The milk collection bin 230 is in communication with the breast cup 210.

[0045] The milk collection bin 230 and the air pump assembly 110 form a first fluid path a. The first fluid path a is provided with a suction silicone bowl 120. The suction silicone bowl 120 separates the first fluid path a.

[0046] The second fluid path b is formed between the breast milk suction chamber 230 and the breast milk collection chamber 220, and a one-way valve 250 is installed in the second fluid path b to control the flow of fluid along the second fluid path b into the breast milk collection chamber 220.

[0047] Specifically, as shown in Figure 3 The breast milk suction chamber 230 is arranged opposite to the breast milk cup 210, and the direction of fluid flow from the breast milk cup 210 into the breast milk suction chamber 230 is axial (i.e. Figure 3 vertical in the middle), and the distribution direction between the air pump assembly 110, the suction silicone bowl 120, and the one-way valve 250 is radial, i.e. Figure 3 horizontal in the middle.

[0048] Further, the air pump assembly 110 has a suction state and a pressure relief state when it is running:

[0049] In the suction state, the suction silicone bowl 120 deforms to generate negative pressure in the breast milk suction chamber 230, the breast milk cup 210 is tightly attached to the breast, and the breast milk is sucked in under the action of the negative pressure in the breast milk suction chamber 230;

[0050] In the pressure relief state, the suction silicone bowl 120 resets to push the breast milk in the breast milk suction chamber 230 into the breast milk collection chamber 220 for collection;

[0051] Therefore, the air pump assembly 110 continuously performs the cycle of suction-exhalation, establishes an action similar to that of a baby sucking, and the breast milk continuously flows out of the breast and into the breast milk suction chamber 230, and is finally collected in the breast milk collection chamber 220.

[0052] In use, since the breast pump is clamped between the user's breast and the breast cup 00, it is not necessary to manually hold the breast pump during the breast pumping process, effectively freeing the user's hands; in particular, for women at work, the impact on work can be minimized, and the breast pumping can be performed during work or during the process of resting on the back.

[0053] In an embodiment, the second body 200 is further provided with a milk outlet 201, which communicates with the breast milk collection chamber 220, and a sealing plug 202 is arranged at the milk outlet 201. After the breast pumping action is completed, the sealing plug 202 is opened, and the breast milk in the breast milk collection chamber 220 is poured into a milk bottle or other container through the milk outlet 201.

[0054] In an embodiment, the second body 200 further includes a second housing 240, which, after being assembled with the breast milk cup 210, forms the breast milk collection chamber 220 and the milk outlet 201.

[0055] As Figure 3 and Figure 4As shown, the breast cup 210 and the second housing 240 are in a split structure; the breast cup 210 comprises an expansion part 211 and a tube part 212, and the breast cup 210 is made of soft silica gel material.

[0056] The expansion part 211 is trumpet-shaped, facilitating the accommodation of the user's breast; the support part 213 is formed radially from the expansion part 211, and when assembled, the support part 213 can be combined with the edge of the second housing 240 by a snap-fit manner, and the disassembly manner is very simple.

[0057] The tube part 212 is inserted into the second housing 240, and the breast cup 212 and the second housing 240 form a breast milk collection chamber 230 therebetween.

[0058] When the breast cup 210 and the second housing 240 are disassembled, it is convenient to clean the breast cup 210 and the second housing 240, and the breast milk collection chamber 230 and the milk collection chamber 220 can be washed clean, and the breast cup 210 and the second housing 240 can be drained or dried for disinfection.

[0059] Among the first body 100 and the second body 200, the first body 100 can further be arranged with a battery, a circuit board and other structures, while the second body 200 is free of electronic components, and the entire second body 200 can be cleaned by soaking in water.

[0060] Continuing as Figure 4 As shown, the breast cup 210 is further formed with a sealing plug 202, which is separated from the milk outlet 201 when the breast cup 210 is disassembled from the second housing 240.

[0061] The sealing plug 202 can be made of silica gel material, and when the breast cup 210 is not disassembled from the second housing 240, the user can exert force to remove the sealing plug 202, and then pour out the breast milk in the milk collection chamber 220.

[0062] The sealing plug 202 and the breast cup 210 are designed as a whole, preventing the sealing plug 202 from being lost.

[0063] In an embodiment, the first body 100 or the second body 200 is provided with a cavity for assembling the suction silica gel bowl 120.

[0064] As shown in Figure 3 and Figure 4 The second housing 240 of the second body 200 is provided with a cavity 260 for assembling the suction silica gel bowl 120, and the cavity 260 is open upward;

[0065] The suction silica gel bowl 120 is bowl-shaped, and the open position of the suction silica gel bowl 120 is formed with a folded edge, which can be clamped at the opening edge of the cavity 260 and close the opening of the cavity 260, thereby blocking the first fluid path a;

[0066] When the air pump assembly 110 inhales, the suction silicone bowl 120 deforms, the gas in the breast milk collection chamber 230 enters the chamber 260, the air pressure in the breast milk collection chamber 230 decreases, that is, negative pressure is generated, and the suction force is generated to suck the breast milk in the breast into the breast milk collection chamber 230.

[0067] When the air pump assembly 110 is released, the suction silicone bowl 120 returns to the original position, and the air in the chamber 260 is pushed into the breast milk collection chamber 230, and then the breast milk in the breast milk collection chamber 230 is pushed into the breast milk collection chamber 220.

[0068] As shown in Figure 3 The shape of the chamber 260 is substantially consistent with the shape of the suction silicone bowl 120 when the suction silicone bowl 120 is not deformed.

[0069] Further, the one-way valve 250 can be an anti-reflux duckbill valve; as shown in Figure 4 The one-way valve 250 is installed at the joint of the breast milk collection chamber 220 and the breast milk collection chamber 230; the one-way valve 250 controls the breast milk to flow from the breast milk collection chamber 230 to the breast milk collection chamber 220, and cannot flow from the breast milk collection chamber 220 to the breast milk collection chamber 230.

[0070] When the second machine body 200 and the first machine body 100 are disassembled, the second machine shell 240 and the breast milk cover 210 are further disassembled, and the suction silicone bowl 120 and the one-way valve 250 can be conveniently disassembled and cleaned.
