Description

Technical Field

[0001] The present invention relates to a breast pump, and in particular to a breast pump, a milk pumping device and a control method for the breast pump. Background Art

[0002] In recent years, wearable breast pumps have become popular, allowing users to place them inside their underwear for hands-free use. For example, in a Chinese utility model patent with authorization publication number CN216571014U, a wearable breast pump is disclosed, which includes a breast pump main unit, a breast pump cylinder, a milk storage cup, a bell housing, and a duckbill valve. The breast pump main unit is connected to the breast pump cylinder, the breast pump cylinder is connected to the milk storage cup, the milk storage cup is connected to the bell housing, and the duckbill valve is connected to the bell housing. The breast pump main unit is used to contract the breast pump cylinder to generate negative pressure at the bell housing, thereby allowing the bell housing to suck milk. The duckbill valve is a one-way valve that is sealed when the breast pump cylinder contracts and is opened when the breast pump cylinder returns to its original shape, connecting the bell housing and the milk storage cup to drain milk into the milk storage cup. The horn cover includes a horn-shaped cover body and an assembly portion that are interconnected. An assembly through hole for installing the duckbill valve is provided below the assembly portion, and the assembly portion is connected to the milk suction channel. One of the problems with the existing technology is that the wearable breast pump relies on underwear to hold the horn cover close to the breast. This causes the wearable breast pump to slide down due to gravity, causing the horn cover to be misaligned with the breast. Once the horn cover is misaligned with the breast, it will further lead to the inability to properly suck milk. One of the problems with the existing technology is that the wearable breast pump cannot massage the breast during the milk suction process, which not only leads to low milk suction efficiency but also a small amount of milk.

[0046] Reference is made to the accompanying drawings of the present invention. Figures 1 to 6 A breast pump according to a preferred embodiment of the present invention will be disclosed and explained in the following description, wherein the breast pump includes at least a milk pumping device 1000 and a host 2000, and the milk pumping device 1000 is connected to the host 2000.

[0047] Specifically, the milk pumping device 1000 includes an assembly part 10 , an elastic diaphragm 20 , a milk discharge one-way valve 30 and a speaker cover 40 .

[0048] More specifically, see the attached Figure 5 and Figure 6 The assembly part 10 has a milk suction chamber 101, a first gas channel 102, a second gas channel 103, an assembly opening 104 and a milk discharge channel 105. The first gas channel 102, the second gas channel 103, the assembly opening 104 and the milk discharge channel 105 are respectively connected to the milk suction chamber 101. Figures 1 to 6 In the specific example of the breast pump of the present invention shown, the assembly part 10 can be an injection molded part, and the plastic material can be formed into an integral assembly part 10 by means of an injection molding process.

[0049] The elastic diaphragm 20 is provided on the assembly 10 to drive the gas in the milk suction chamber 101 of the assembly 10 to be discharged through the first gas channel 102 , so as to generate high and low negative pressures in the milk suction chamber 101 of the assembly 10 alternately.

[0050] Specifically, the elastic diaphragm 20 is deformable. When the elastic diaphragm 20 is deformed, the elastic diaphragm 20 drives the gas in the milk suction chamber 101 of the assembly 10 to be discharged through the first gas channel 102. In this way, the air pressure in the milk suction chamber 101 of the assembly 10 can be reduced, so that the milk suction chamber 101 of the assembly 10 generates high and low negative pressures alternately. Figures 1 to 6 In the specific example of the breast pump of the present invention shown, the elastic membrane 20 may be made of a silicone material so that the elastic membrane 20 is deformable.

[0051] The specific method of arranging the elastic membrane 20 on the assembly part 10 can be referred to in the attached Figure 5 and Figure 6 The assembly 10 has a diaphragm groove 106 , with the first gas channel 102 communicating with the diaphragm groove 106 . The elastic diaphragm 20 is bowl-shaped, defining a concave cavity 21 . Thus, when the edge of the elastic diaphragm 20 seals against the edge of the diaphragm groove 106 of the assembly 10 , the entire elastic diaphragm 20 sinks into the diaphragm groove 106 of the assembly 10 , thereby reducing the overall volume of the breast pump. In other words, the elastic diaphragm 20 seals the notch of the diaphragm groove 106 of the assembly 10 .

[0052] Preferably, the shape of the elastic diaphragm 20 matches the shape and size of the diaphragm groove 106 of the assembly 10, so that the outer wall of the elastic diaphragm 20 and the inner wall of the assembly 10 defining the diaphragm groove 106 can fit in contact with each other. When the bottom of the elastic diaphragm 20 deforms in a direction away from the bottom of the diaphragm groove 106 of the assembly 10, gas within the milk suction chamber 101 of the assembly 10 can be forced to discharge through the first gas channel 102 into the diaphragm groove 106, thereby reducing the air pressure within the milk suction chamber 101 of the assembly 10 and creating a higher negative pressure within the milk suction chamber 101 of the assembly 10. When the bottom of the elastic diaphragm 20 is deformed toward the bottom of the diaphragm groove 106 of the assembly 10, the gas in the diaphragm groove 106 of the assembly 10 can be driven into the milk suction chamber 101 through the first gas channel 102, so as to increase the air pressure in the milk suction chamber 101 of the assembly 10, so that the milk suction chamber 101 of the assembly 10 has a lower negative pressure. In this way, the elastic diaphragm 20 causes the milk suction chamber 101 of the assembly 10 to alternately generate high and low negative pressures to achieve milk suction.

[0053] The elastic diaphragm 20 can be driven to deform by changing the negative pressure of the concave cavity 21 of the elastic diaphragm 20. When the negative pressure of the concave cavity 21 of the elastic diaphragm 20 increases, the bottom of the elastic diaphragm 20 deforms in a direction away from the bottom of the diaphragm groove 106 of the assembly 10. At this time, the gas in the milk suction cavity 101 of the assembly 10 can be driven to be discharged to the diaphragm groove 106 through the first gas channel 102, so as to reduce the negative pressure in the milk suction cavity 101 of the assembly 10. The air pressure in the milking chamber 101 is increased, resulting in a higher negative pressure in the milking chamber 101. When the negative pressure in the concave cavity 21 of the elastic diaphragm 20 decreases, the bottom of the elastic diaphragm 20 deforms toward the bottom of the diaphragm groove 106 of the assembly 10. At this time, the air in the diaphragm groove 106 of the assembly 10 can be driven into the milking chamber 101 through the first air channel 102, thereby increasing the air pressure in the milking chamber 101 of the assembly 10 and reducing the negative pressure in the milking chamber 101. How to change the negative pressure in the concave cavity 21 of the elastic diaphragm 20 will be explained later.

[0054] The milk discharge one-way valve 30 is provided on the assembly part 10, and the milk discharge one-way valve 30 is used to selectively open and close the milk discharge channel 105 of the assembly part 10. When the milk discharge one-way valve 30 closes the milk discharge channel 105 of the assembly part 10, the sucked milk is temporarily stored in the milk suction chamber 101 of the assembly part 10. When the milk discharge one-way valve 30 opens the milk discharge channel 105 of the assembly part 10, the milk temporarily stored in the milk suction chamber 101 of the assembly part 10 is discharged through the milk discharge channel 105.

[0055] In order to set the milk discharge one-way valve 30 on the assembly part 10, refer to the attached Figure 2 and Figure 5 The assembly part 10 has a mounting post 11, the milk discharge channel 105 passes through the mounting post 11, and the milk discharge one-way valve 30 has a valve slot 31. The mounting post 11 of the assembly part 10 is inserted into the valve slot 31 of the milk discharge one-way valve 30. Based on the friction generated between the milk discharge one-way valve 30 and the mounting post 11 of the assembly part 10, the milk discharge one-way valve 30 is set on the assembly part 10.

[0056] Reference Attachment Figures 3 to 6 The bell cover 40 includes a main cover body 41 and a deformable small cover ring 42. The main cover body 41 has a cover cavity 411 and a front opening 412, a rear opening 413, and an air passage 414, which are respectively connected to the cover cavity 411. The small cover ring 42 is disposed on the main cover body 41 and is located in the cover cavity 411 of the main cover body 41. The rear portion of the main cover body 41 is mounted on the assembly part 10 through the assembly opening 104 of the assembly part 10. The cover cavity 411 of the main cover body 41 is connected to the milk suction cavity 101 of the assembly part 10 through the rear opening 413. The air passage 414 of the bell cover 40 is connected to the second air passage 103 of the assembly part 10.

[0057] Preferably, the assembly part 10 has a hook groove 110, and the tail of the main cover body 41 has a hook platform 4101. After the tail of the main cover body 41 is installed on the assembly part 10 through the assembly opening 104 of the assembly part 10, the hook platform 4101 of the main cover body 41 is hooked into the hook groove 110 of the assembly part 10 to reliably install the main cover body 41 on the assembly part 10.

[0058] In the attached Figures 1 to 6In this specific example of the breast pump of the present invention, the main housing 41 of the bell housing 40 is deformable, allowing it to self-attach to the breast. Preferably, the main housing 41 and the small housing ring 42 of the bell housing 40 are integrally formed. For example, silicone material can be integrally formed into the bell housing 40 via an injection molding process. Alternatively, in other examples of the breast pump of the present invention, the main housing 41 and the small housing ring 42 of the bell housing 40 are separately formed, and the small housing ring 42 is detachably mounted to the main housing 41. This arrangement not only facilitates cleaning of the breast pump device 1000, but also allows the user to replace the small housing ring 42 with the appropriate size.

[0059] Reference Attachment Figure 6 When the user uses the breast pumping device 1000, the main cover body 41 of the horn cover 40 covers a part of the breast, and the front opening 412 of the main cover body 41 is closed by the breast. The small cover ring 42 presses against the back of the areola to form a massage cavity 100 between the main cover body 41, the small cover ring 42 and the breast. The air channel 414 of the main cover body 41 is connected to the massage cavity 100. When the gas in the massage cavity 100 is discharged through the air channel 414 of the main cover body 41, the air pressure in the massage cavity 100 can be reduced. For example, the massage cavity 100 can form a negative pressure environment, so that the horn cover 40 is self-adsorbed on the breast. In this way, the breast pumping device 1000 can be prevented from sliding down relative to the breast.

[0060] When a user wears the breast pumping device 1000 on their breasts through underwear, when the gas in the massage chamber 100 is discharged through the air passage 414 of the main cover body 41, the air pressure in the massage chamber 100 can be reduced to form a negative pressure environment. When the external environment gas is blown into the massage chamber 100 through the air passage 414 of the main cover body 41, the air pressure in the massage chamber 100 can be increased to form a positive pressure environment. In this way, the massage chamber 100 can alternately generate high and low pressures, driving the small cover ring 42 to deform and massage the posterior areola, thereby stimulating lactation and increasing milk production. It is understood that when a user wears the breast pumping device 1000 on their breasts through underwear, the massage chamber 100 can also alternately generate high and low negative pressures, driving the small cover ring 42 to deform and massage the posterior areola, thereby stimulating lactation and increasing milk production.

[0061] That is to say, the breast pump of the present invention provides a naked suction mode and a massage mode. When the user selects the naked suction mode, the massage chamber 100 needs to continuously form a negative pressure environment to ensure that the horn cover 40 is firmly adsorbed on the breast. When the user selects the massage mode, the massage chamber 100 can alternately generate high and low negative pressures, or alternately generate positive and negative pressures, to drive the small cover ring 42 to deform and massage the back of the areola by the small cover ring 42, thereby stimulating lactation and increasing milk production.

[0062] It can be understood that the pressure of the negative pressure in the massage chamber 100 is related to the amount of residual air in the massage chamber 100. When the massage chamber 100 is in a negative pressure environment, the smaller the amount of residual air in the massage chamber 100, the greater the pressure of the negative pressure in the massage chamber 100, and the more the amount of residual air in the massage chamber 100, the smaller the pressure of the negative pressure in the massage chamber 100. When the massage chamber 100 is in a positive pressure environment, the smaller the residual amount in the massage chamber 100, the smaller the pressure of the positive pressure in the massage chamber 100, and the more the amount of residual air in the massage chamber 100, the greater the pressure of the positive pressure in the massage chamber 100. Therefore, the pressure in the massage chamber 100 can be controlled by the discharge amount and the blowing amount of the air in the massage chamber 100 through the second gas channel 103 of the assembly 10, so that the milk suction device 1000 meets the usage needs of different users.

[0063] When a user uses the breast pump, the breast pump is in a state where the massage chamber 100 is always in a negative pressure environment. The milk suction device 1000 can be self-adhesive to the breast. During the milk suction process, the massage chamber 100 may leak air due to the user's activities, causing the negative pressure in the massage chamber 100 to change unexpectedly. When the massage chamber 100 leaks air, the breast pump allows the air in the massage chamber 100 to be discharged again through the second air channel 103 of the assembly 10, so that the pressure in the massage chamber 100 remains stable, thereby improving the user's comfort when using the breast pump. In some examples of the present invention, a sensor can be provided on the host 2000 to detect the pressure in the massage chamber 100.

[0064] Continue to refer to the attached Figure 5 and Figure 6 The speaker cover 40 further includes a blocking ring 43 , which extends backward from the small cover ring 42 so that the blocking ring 43 protrudes from the inner wall of the main cover body 41 .

[0065] When the user uses the breast pumping device 1000, the small cover ring 42 and the blocking ring 43 both press against the back of the areola, and the small cover ring 42 extends from the back of the areola toward the breast base, and the blocking ring 43 extends from the back of the areola toward the nipple. During the milk pumping process, when the air pressure in the milk suction chamber 101 of the assembly 10 decreases, the areola is pulled toward the milk suction chamber 101 of the assembly 10. Since the blocking ring 43 presses against the back of the areola, the blocking ring 43 has the function of blocking the areola from entering the milk suction chamber 101 of the assembly 10. At this time, the areola is squeezed to squeeze out the milk and temporarily store it in the milk suction chamber 101 of the assembly 10. This is conducive to improving the milk suction efficiency of the breast pump.

[0066] Preferably, the barrier ring 43 is deformable, so that while providing resistance, it deforms toward the milking cavity 101 of the assembly 10. This prevents the areola from being squeezed while providing resistance, thereby improving comfort. Preferably, the distal end of the barrier ring 43 extends in a backward curve, so that when a user wears the breast pumping device 1000, the end face of the barrier ring 43 can be prevented from contacting the nipple, thereby improving the user's comfort when using the breast pump.

[0067] In the attached Figures 1 to 6 In the illustrated embodiment of the breast pump of the present invention, the main housing 41 , the small housing ring 42 and the blocking ring 43 of the bell housing 40 are integral.

[0068] Further, please refer to the attached Figure 5 and Figure 6 The main cover body 41 includes a rear section 415 and a front section 416, and the front section 416 extends obliquely forward from the rear section 415, that is, the rear section 415 and the front section 416 have different extension directions. The main cover body 41 forms a cover groove 417 at the connection between the rear section 415 and the front section 416, and the air channel 414 of the main cover body 41 is formed at the position of the cover groove 417 of the main cover body 41. In this way, on the one hand, When the user wears the breast pumping device 1000, the cover groove 417 of the main cover body 41 and the connection between the main cover body 41 and the small cover ring 42 enable the massage cavity 100 to be formed between the main cover body 41, the small cover ring 42 and the breast. On the other hand, the front opening 412 of the main cover body 41 can have a smaller size, so that the front section 416 of the main cover body 41 can provide a gripping force for gripping the back of the breast, which is conducive to the breast pumping device 1000 being worn securely.

[0069] Continue to refer to the attached Figures 1 to 6 The outer wall of the main cover body 41 has an assembly column 418, and the air channel 414 of the main cover body 41 passes through the assembly column 418, wherein the assembly part 10 has an assembly hole 107, and the assembly hole 107 is connected to the second gas channel 103, wherein the assembly column 418 of the main cover body 41 is inserted into the assembly hole 107 of the assembly part 10. In this way, on the one hand, the horn cover 40 can be reliably installed on the assembly part 10, and on the other hand, the assembly column 418 of the main cover body 41 and the assembly hole 107 of the assembly part 10 can ensure that the main cover body 41 and the second gas channel 103 of the assembly part 10 are connected and avoid air leakage at this connection position. On the other hand, the assembly column 418 of the main cover body 41 and the assembly hole 107 of the assembly part 10 cooperate with each other to position the installation direction of the horn cover 40.

[0070] Further, please refer to the attached Figures 1 to 6 The breast pump further includes a shell 50, which is mounted on the assembly part 10, and the elastic diaphragm 20 is clamped between the assembly part 10 and the shell 50, so that the elastic diaphragm 20 can be reliably set on the assembly part 10.

[0071] Preferably, the breast pump forms a milk storage chamber 60 between the shell 50 and the assembly 10, and the milk discharge one-way valve 30 is located in the milk storage chamber 60. When the milk discharge one-way valve 30 opens the milk discharge channel 105 of the assembly 10, the milk temporarily stored in the milk suction chamber 101 of the assembly 10 is discharged to the milk storage chamber 60 through the milk discharge channel 105.

[0072] In addition, the shell 50 further has a first air hole 51 and a second air hole 52, wherein the first air hole 51 is connected to the concave cavity 21 of the elastic diaphragm 20, and the second air hole 52 is connected to the second gas channel 103 of the assembly 10. The main unit 2000 has a first pump body 2001, a second pump body 2002 and an electromagnetic valve 2003. The three ends of a three-way pipe 3000 are respectively connected to the first air hole 51 of the shell 50, the electromagnetic valve 2003 and an opening of the first pump body 2001, and the two ends of an air pipe 4000 are respectively connected to the second air hole 52 of the shell 50 and an opening of the second pump body 2002. During milking, the first pump body 2001 works continuously. When the solenoid valve 2003 is closed, the negative pressure in the cavity 21 of the elastic diaphragm 20 increases, and the bottom of the elastic diaphragm 20 deforms in a direction away from the bottom of the diaphragm groove 106 of the assembly 10. At this time, the gas in the milking cavity 101 of the assembly 10 can be driven to be discharged to the diaphragm groove 106 through the first gas channel 102 to reduce the air pressure in the milking cavity 101 of the assembly 10. When the solenoid valve 2003 is opened, the negative pressure in the cavity 21 of the elastic diaphragm 20 decreases, and the bottom of the elastic diaphragm 20 moves toward the bottom of the diaphragm groove 106 close to the assembly 10. When the massage cavity 100 is deformed in the direction of the upper portion, the gas in the diaphragm groove 106 of the assembly part 10 can be driven into the milk suction cavity 101 through the first gas channel 102 to raise the milk suction cavity 101 of the assembly part 10, so that the milk suction cavity 101 of the assembly part 10 alternately generates high and low negative pressures for milk suction; when the massage cavity 100 leaks, the second pump body 2002 works to extract the gas in the massage cavity 100 through the air channel 414 of the main cover body 41, the second gas channel 103 of the assembly part 10 and the second air hole 52 of the shell 50, thereby reducing the air pressure in the massage cavity 100 to ensure that the milk suction device 1000 can be reliably self-adsorbed on the breast.

[0073] Preferably, the elastic diaphragm 20 has a diaphragm hole 22, and the column of the assembly part 10 for defining the second gas channel 103 and the column of the shell 50 for defining the second air hole 52 are respectively inserted into the diaphragm hole 22 of the elastic diaphragm 20. In this way, on the one hand, the elastic diaphragm 20 can be reliably arranged between the assembly part 10 and the shell 50, and on the other hand, the diaphragm hole 22 of the elastic diaphragm 20 can connect the second gas channel 103 of the assembly part 10 and the second air hole 52 of the shell 50.

[0074] Figure 7A variation of the milk extraction device 1000 of the breast pump according to the preferred embodiment of the present invention is shown. Figures 1 to 6 The difference between the milk extraction device 1000 of the breast pump shown is that Figure 7 In the illustrated example of the breast pump's milk extraction device 1000, the air passage 414 of the main housing 41 is formed in the rear portion 415 of the main housing 41. That is, the inner opening of the air passage 414 of the main housing 41 faces the outer wall of the small housing ring 42. When a user wears the breast extraction device 1000, the massage chamber 100 is formed between the main housing 41, the small housing ring 42, and the breast. The first pump body 2001 and the solenoid valve 2003 cooperate to alternately generate high and low negative pressures in the milk extraction chamber 101 of the assembly 10 to extract milk. The second pump body 2002 alternately generates high and low pressures in the massage chamber 100, driving the small housing ring 42 to deform and massage the posterior areola. This helps stimulate lactation and increase milk production.

[0075] When the user selects the bare suction mode, the bell housing 40 automatically adheres to the breast, and the second pump body 2002 draws air from the massage cavity 100 through the air passage 414 of the main housing 41, creating a negative pressure environment within the massage cavity 100, thereby allowing the bell housing 40 to securely adhere to the breast. Preferably, the breast pump can detect the pressure of the massage cavity 100 in real time via a sensor provided on the main unit 2000, and adjust the minimum negative pressure value of the massage cavity 100 based on the pressure state of the massage cavity 100, thereby ensuring that the milk suction device 1000 securely adheres to the breast.

[0076] When the user selects massage mode, the user can wear the breast pump device 1000 on the breast with the aid of underwear. The second pump body 2002 and the other solenoid valve 2003 cooperate to cause the massage chamber 100 to alternately generate high and low negative pressures, driving the small cover ring 42 to deform and massage the back of the areola. This helps stimulate lactation and increase milk production. In other words, the massage chamber 100 is always in a negative pressure environment. Alternatively, the second pump body 2002 can extract the gas in the massage cavity 100 through the air channel 414 of the main cover body 41, the second air channel 103 of the assembly part 10 and the second air hole 52 of the shell 50, so that the massage cavity 100 forms a negative pressure environment, or can blow the gas into the massage cavity 100 through the second air hole 52 of the shell 50, the second air channel 103 of the assembly part 10 and the air channel 414 of the main cover body 41, so that the massage cavity 100 forms a positive pressure environment. This is repeated, and the massage cavity 100 alternately generates positive and negative pressures to drive the small cover ring 42 to deform so that the small cover ring 42 massages the back of the areola, which is beneficial to stimulate lactation and increase milk production.

[0077] According to another aspect of the present invention, a control method for the breast pumping device 1000 is further provided, wherein the control method comprises the following steps: (a) when a user wears the breast pumping device 1000, forming the massage chamber 100 between the main housing 41 of the bell housing 40 of the breast pumping device 1000, the small housing ring 42 mounted on the main housing 41, and the breast; (b) causing the breast pumping chamber 101 of the breast pumping device 1000 to alternately generate high and low negative pressures to extract milk; and (c) causing the massage chamber 100 to alternately generate high and low pressures to deform the small housing ring 42, thereby massaging the posterior areola. In this manner, the breast pumping device 1000 can stimulate lactation and increase milk production during the breast pumping process.

[0078] In a specific example of the control method of the present invention, in step (c), the massage chamber 100 is caused to alternately generate high and low negative pressures to drive the small cover ring 42 to deform so that the small cover ring 42 massages the back of the areola to stimulate lactation and increase milk production.

[0079] In another specific example of the control method of the present invention, in step (c), the massage chamber 100 is caused to alternately generate positive pressure and negative pressure to drive the small cover ring 42 to deform so that the small cover ring 42 massages the posterior part of the areola to stimulate lactation and increase milk production.

[0080] Attachment Figures 8 to 14A breast pump according to another preferred embodiment of the present invention is shown, wherein the breast pump comprises at least a milk suction device 1000A and a host 2000A, and the milk suction device 1000A is connected to the host 2000A.

[0081] The breast pump device 1000A includes an assembly part 10A, an elastic diaphragm 20A, a milk discharge one-way valve 30A, and a speaker cover 40A, wherein the assembly part 10A has a first gas channel 102A, a second gas channel 103A, an assembly opening 104A, a milk discharge channel 105A, and an assembly cavity 108A. The speaker cover 40A is respectively connected to the assembly cavity 108A, wherein the speaker cover 40A includes a main cover body 41A and a deformable small cover ring 42A, the main cover body 41A has a cover cavity 411A, a front opening 412A, a rear opening 413A, an airway 414A and a milk channel 419A, the small cover ring 42A is set on the main cover body 41A and located in the cover cavity 411A, the elastic diaphragm 20A is set at the tail of the main cover body 41A for sealing The rear opening 413A of the main cover body 41A is closed, and the milk suction device 1000A forms a milk suction chamber 101A between the main cover body 41A and the elastic diaphragm 20A. The tail of the main cover body 41A is installed in the assembly chamber 108A through the assembly opening 104A of the assembly part 10A. The milk suction device 1000A forms a negative pressure chamber 1001A between the elastic diaphragm 20A and the assembly part 10A. The first gas channel 102A is connected to the negative pressure chamber 1001A, the air channel 414A of the main cover body 41A is connected to the second gas channel 103A of the assembly part 10A, the milk channel 419A of the main cover body 41A is connected to the milk discharge channel 105A of the assembly part 10A, and the milk discharge one-way valve 30A is provided on the assembly part 10A for selectively opening and closing the milk discharge channel 105A of the assembly part 10A.

[0082] The main unit 2000A has a first pump body 2001A, a second pump body 2002A and a solenoid valve 2003A. The three ends of a three-way pipe 3000A are respectively connected to the first gas channel 102A of the assembly 10A, the solenoid valve 2003A and an opening of the first pump body 2001A. The two ends of an air pipe 4000A are respectively connected to the second gas channel 103A of the assembly 10A and an opening of the second pump body 2002A.

[0083] During milk extraction, the breast closes the front opening 412A of the main cover body 41A, and the small cover ring 42A presses against the back of the areola. A massage chamber 100A is formed between the main cover body 41A, the small cover ring 42A, and the breast. The air passage 414A of the main cover body 41A is connected to the massage chamber 100A. The first pump body 2001A works continuously. When the solenoid valve 2003A is closed, the first pump body 2001A extracts the gas in the negative pressure chamber 1001A of the milk suction device 1000A through the first gas passage 102A of the assembly part 10A. The negative pressure in the negative pressure chamber 1001A increases, and the bottom of the elastic diaphragm 20A deforms toward the bottom of the assembly chamber 108A close to the assembly part 10A. At this time, the space of the milk suction chamber 101A of the milk suction device 1000A increases. The pressure of the negative pressure increases. When the solenoid valve 2003A is opened, air is taken into the negative pressure chamber 1001A of the milk suction device 1000A, which reduces the pressure of the negative pressure in the negative pressure chamber 1001A. The bottom of the elastic diaphragm 20A is deformed toward the bottom of the assembly chamber 108A away from the assembly part 10A. At this time, the space of the milk suction chamber 101A of the milk suction device 1000A is reduced, and the pressure of the negative pressure is reduced. In this way, the milk suction chamber 101A of the milk suction device 1000A alternately generates high and low negative pressures to achieve milk suction. The second pump body 2002A can extract the gas in the massage cavity 100A through the air channel 414A of the main cover body 41A and the second air channel 103A of the assembly part 10A to form a negative pressure environment in the massage cavity 100A, and can also blow the gas into the massage cavity 100A through the second air channel 103A of the assembly part 10A and the air channel 414A of the main cover body 41A to form a positive pressure environment in the massage cavity 100A. This process is repeated, and the massage cavity 100A alternately generates positive pressure and negative pressure to drive the small cover ring 42A to deform and allow the small cover ring 42A to massage the back of the areola, which is beneficial to stimulate lactation and increase milk volume.

[0084] Preferably, the inner opening of the air passage 414A of the main cover body 41A faces the outer wall of the small cover ring 42A, so that when the user wears the breast pumping device 1000A, the massage chamber 100A is formed between the main cover body 41A, the small cover ring 42A and the breast, and the first pump body 2001A and the solenoid valve 2003A cooperate with each other to enable the breast pumping chamber 101A of the breast pumping device 1000A to alternately generate high and low negative pressures to suck milk. Alternatively, the second pump body 2002A can cause the massage cavity 100A to alternately generate positive pressure and negative pressure to drive the small cover ring 42A to deform and massage the back of the areola by the small cover ring 42A, which is beneficial to stimulate lactation and increase milk volume. Alternatively, the second pump body 2002A can cause the massage cavity 100A to alternately generate high and low negative pressures to drive the small cover ring 42A to deform and massage the back of the areola by the small cover ring 42A, which is beneficial to stimulate lactation and increase milk volume.

[0085] In the attached Figures 8 to 14 In this specific example of the breast pump of the present invention, the assembly 10A can be an injection-molded part. Plastic material can be used to form the assembly 10A into a single piece through an injection molding process.

The milk discharge passage 105A extends through the mounting post 11A, the first gas passage 102A extends through the first tubular post 12A, and the second gas passage 103A extends through the second tubular post 13A. The milk discharge check valve 30A includes a valve slot 31A. The mounting post 11A of the assembly 10A is inserted into the valve slot 31A of the milk discharge check valve 30A. The milk discharge check valve 30A is positioned within the assembly 10A due to friction between the mounting post 11A and the mounting post 11A. The first pipe string 12A of the assembly 10A is inserted into one end of the tee pipe 3000A, so that the tee pipe 3000A is connected to the first gas channel 102A of the assembly 10A. The second pipe string 13A of the assembly 10A is inserted into one end of the gas pipe 4000A, so that the gas pipe 4000A is connected to the second gas channel 103A of the assembly 10A.

[0086] In the attached Figures 8 to 14In this specific example of the breast pump of the present invention, the main cover 41A and the elastic diaphragm 20A are integrally formed. For example, silicone material can be used to form the integral main cover 41A and the elastic diaphragm 20A through an injection molding process. The small cover ring 42A is detachably mounted on the main cover 41A. It is understood that the small cover ring 42A can also be made of silicone material. In other specific examples of the breast pump of the present invention, the main cover 41A, the small cover ring 42A, and the elastic diaphragm 20A can be integrally formed.

[0087] Furthermore, the main cover body 41A has an insertion hole 410A, which is connected to the air channel 414A, and the assembly part 10A has an insertion column 14A, and the second gas channel 103A passes through the insertion column 14A, wherein the insertion column 14A of the assembly part 10A is inserted into the insertion hole 410A of the main cover body 41A. In this way, on the one hand, the air channel 414A of the main cover body 41A and the second gas channel 103A of the assembly part 10A are connected and avoid air leakage at the installation position of the main cover body 41A and the assembly part 10A. On the other hand, the insertion hole 410A of the main cover body 41A and the insertion column 14A of the assembly part 10A cooperate with each other to position the installation direction of the main cover body 41A.

[0088] Furthermore, the milk suction device 1000A includes a milk bottle 70A, which is installed on the assembly part 10A and covers the milk discharge one-way valve 30A. The milk discharged from the milk suction chamber 101A of the milk suction device 1000A through the milk discharge one-way valve 30A can be collected in the milk bottle 70A.

[0089] Attachment Figure 15 and Figure 16 A modified example of the milk extraction device 1000A of the breast pump of the preferred embodiment is shown. Figures 8 to 14 The difference between the milk extraction device 1000A of the breast pump shown is that Figure 15 and Figure 16In the specific example of the breast pump device 1000A of the present invention shown, the bell cover 40A includes an anti-sticking portion 44A, which is provided on the outer wall of the small cover ring 42A, and the anti-sticking portion 44A extends from the front edge of the small cover ring 42A to the rear direction, and the position of the inner opening of the airway 414A of the main cover body 41A corresponds to the position of the anti-sticking portion 44A. When the gas in the massage cavity 100A is extracted through the air passage 414A of the main cover body 41A and the second gas passage 103A of the assembly part 10A to form a negative pressure environment in the massage cavity 100A, the small cover ring 42A is deformed toward the main cover body 41A and the outer wall of the small cover ring 42A may contact the inner wall of the main cover body 41A. By providing the anti-sticking portion 44A on the outer wall of the small cover ring 42A, the speaker cover 40A can avoid the outer wall of the small cover ring 42A and the inner wall of the main cover body 41A from adhering to each other, thereby ensuring that the gas in the massage cavity 100A can be extracted at any time through the air passage 414A of the main cover body 41A and the second gas passage 103A of the assembly part 10A.

[0090] In the attached Figure 15 and Figure 16 In the illustrated embodiment of the breast pump of the present invention, the anti-adhesion portion 44A is a rib protruding from the outer wall of the small cover ring 42A. Alternatively, in other embodiments of the breast pump of the present invention, the anti-adhesion portion 44A may be a groove.

[0091] Attachment Figure 17 and Figure 18 A modified example of the milk extraction device 1000A of the breast pump of the preferred embodiment is shown. Figure 15 and Figure 16 The difference between the milk extraction device 1000A of the breast pump shown is that Figure 17 and Figure 18In the specific example of the breast pump device 1000A of the present invention shown, the anti-sticking portion 44A is provided on the inner wall of the main cover body 41A, and the anti-sticking portion 44A extends from the inner opening of the airway 414A toward the edge of the main cover body 41A. When the gas in the massage cavity 100A is extracted through the air passage 414A of the main cover body 41A and the second gas passage 103A of the assembly part 10A to form a negative pressure environment in the massage cavity 100A, the small cover ring 42A is deformed toward the main cover body 41A and the outer wall of the small cover ring 42A may contact the inner wall of the main cover body 41A. By providing the anti-sticking portion 44A on the inner wall of the main cover body 41A, the speaker cover 40A can avoid the outer wall of the small cover ring 42A and the inner wall of the main cover body 41A from adhering to each other, thereby ensuring that the gas in the massage cavity 100A can be extracted at any time through the air passage 414A of the main cover body 41A and the second gas passage 103A of the assembly part 10A.

[0092] In the attached Figure 17 and Figure 18 In the illustrated embodiment of the breast pump of the present invention, the anti-adhesion portion 44A is a groove that is recessed into the inner wall of the main housing 41A. Alternatively, in other embodiments of the breast pump of the present invention, the anti-adhesion portion 44A may be a rib.
