By setting the inverter 6 and the adjustment knob 13, the user can control the size of the working suction force of the vacuum pump 3 by adjusting the knob 13, so that the breast pump can adapt to different occasions.

[0043] A protective cover 12 is mounted on the tank cover 2 by snap-fitting, and the battery 4, vacuum pump 3, controller 5 and inverter 6 are all located inside the protective cover 12. The protective cover 12 can protect the various components inside from the influence of the external environment. The switch 9 and the charging interface 10 are both mounted on the outer wall of the protective cover 12. The adjustment knob 13 is also mounted on the outer wall of the protective cover 12 so that the adjustment knob 13 is exposed outside the protective cover 12, so that the user can directly turn the adjustment knob 13 outside the breast pump. At the same time, the protective cover 12 is provided with a plurality of avoidance holes corresponding to the indicator lights 11, so that each indicator light 11 can extend from these corresponding avoidance holes to the outside of the protective cover 12, so that the user can directly see the indicator lights 11 outside the breast pump.

[0044] Specifically, Figure 8 As shown, the milking head 7 includes a milk cup 14 and a milk lining inner tube 15, wherein the milk lining inner tube 15 is located inside the milk cup 14, so that a closed pulsating space 16 is formed between the milk cup 14 and the milk lining inner tube 15, wherein the milk lining inner tube 15 is a component made of a flexible material, such as a silicone tube, which can produce elastic deformation. The milking head 7 is provided with a pulsating joint 17 and a milking joint 19, wherein the pulsating joint 17 is arranged on the milk cup 14 and connected to the pulsating space 16, and the milking joint 19 is connected to the milk lining inner tube 15. An exhaust joint 25 connecting the inside and outside of the tank body 1 is installed on the tank cover 2, and the vacuum pump 3 is connected to the exhaust pipe, and the vacuum pump 3 is connected to the exhaust joint 25 through one end of the exhaust pipe to extract the air inside the tank body 1, so that negative pressure is generated inside the tank body 1. Among them, in addition to the above-mentioned structure, the milking head 7 can also be a milking device described in the Chinese patent document with the authorization announcement number CN206547543U.

[0045] like Figure 5-Figure 7As shown, the protective cover 12 is provided with a first joint 21, which is connected to the inner and outer sides of the protective cover 12. The exhaust pipe is provided with a pulsating pipe connected thereto, which is divided into a first pipe section 28 and a second pipe section 18, one end of the first pipe section 28 is connected to the exhaust pipe, the other end of the first pipe section 28 is connected to one end of the first joint 21, the other end of the first joint 21 is connected to one end of the second pipe section 18, and the other end of the second pipe section 18 is connected to the pulsating joint 17. At the same time, the exhaust pipe is divided into a third pipe section 29 and a fourth pipe section 30. A tee 26 is installed in the protective cover 12, and the tee 26 has three joints, and the first pipe section 28, the third pipe section 29 and the fourth pipe section 30 are respectively connected to a joint, wherein the third pipe section 29 is also connected to the vacuum pump 3, and the fourth pipe section 30 is also connected to the exhaust joint 25.

[0046] A pulser 31 is installed on the first pipe section 28, and the pulser 31 is electrically connected to the controller 5, so that the controller 5 can control the operation of the pulser 31, and the pulser 31 is located inside the protective cover 12. The pulser 31 can make the pulsation space 16 and the space inside the tank body 1 communicate with each other at intervals, so that the milk lining inner tube 15 is deformed periodically, so that the milking head 7 produces an action similar to that of a cow or calf drinking milk, thereby improving the efficiency of milk production of cows and sheep. The pulser 31 in this embodiment can be a solenoid valve, which is used to control the on and off of the first pipe section 28.

[0047] The tank cover 2 is provided with a second joint 22 for connecting the inside and outside of the tank body 1. The second joint 22 has two ends disposed on both sides of the tank cover 2. A milking tube 20 is connected between the end of the second joint 22 located outside the tank cover 2 and the milking joint 19. In order to facilitate users to distinguish the pulsating tube and the milking tube 20 and enable the pulsating tube and the milking tube 20 to be correctly connected to the corresponding joints, the outer diameters of the pulsating tube and the milking tube 20 may be different, that is, one has a larger diameter and the other has a smaller diameter.

[0048] In order to reduce the noise generated when the vacuum pump 3 is working, a muffler 23 is connected to the vacuum pump 3 , and the muffler 23 is installed on the protective cover 12 .

At the same time, in order to prevent foreign matter in the external environment from entering the protective cover 12, an isolation net 24 can be installed at the notch, and the isolation net 24 can be formed integrally with the protective cover 12.

[0050] By installing the vacuum pump 3 on the tank cover 2, the need to carry the vacuum pump 3 as a power component separately is avoided, which makes it convenient for users to carry it. At the same time, because the vacuum pump 3 is directly installed on the tank cover 2, the vacuum pump 3 can be directly connected to the interior of the tank body 1, thereby extracting the air in the tank body 1 to generate negative pressure in the tank body 1. Because the vacuum pump 3 and the tank cover 2 are integrated together, the connection between the vacuum pump 3 and the tank body 1 does not need to be disassembled, and can be permanently connected. Therefore, in actual use, users can reduce the connection of two joints, which greatly improves the probability of users making correct connections.

[0051] Meanwhile, in this embodiment, the controller 5 is electrically connected to three indicator lights 11, which have an indicating function. The three indicator lights 11 correspond to the indicator light of the power supply, the indicator light of the vacuum pump and the indicator light of the charging, respectively.

[0052] The working process of this utility model is as follows:

[0053] When using the breast pump, the milk cup 14 is sleeved on the milk source, and the milk liner inner tube 15 will fit on the milk source. The breast pump is started, and the sucked milk will flow into the tank body 1 along the milk liner inner tube 15 and the milking tube 20 in sequence. While the milk flows in the milking tube 20, the pulser 31 will be opened and closed at intervals, so that the pulsation space 16 and the space inside the tank body 1 are connected at intervals, so that the milk liner inner tube 15 is deformed periodically, so that the milking head 7 produces an action similar to that of a cow or calf drinking milk.

[0054] Example 2

[0055] The difference between this embodiment and embodiment 1 is that there are two milking heads 7 in this embodiment, the milking tube 20 is connected to the two milking heads 7 at the same time, and the pulsation tube is also connected to the two milking heads 7 at the same time.
