Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] Embodiment 1: like Figures 1 to 5 A wearable breast pump that is easy to suck is shown, comprising a main body shell 1 and a suction cup member 2, the main body shell 1 has a negative pressure chamber 12 and a milk storage chamber 13 respectively, the suction cup member 2 has a milk suction channel 24 respectively connected to the outside and the milk storage chamber 13, the suction cup member 2 is detachably mounted on the main body shell 1, the suction cup member 2 has an adsorption cavity 23 on one side for fitting the user's skin, the main body shell 1 comprises a suction device 3 and a suction pipeline structure 4 for sucking internal air to form negative pressure, the suction device 3 is respectively connected to the adsorption cavity 23 and the negative pressure chamber 12.

[0031] More specifically, the host housing 1 is the device shell of the breast pump, which can be used to install components and store milk. The suction cup 2 is the suction cup structure of the breast pump, which can be used to fit the user's breast skin for the breast pump to perform the suction function and milk suction function. The suction cup 2 is installed on the host housing 1 to form a negative pressure chamber 12 and a milk storage chamber 13 that are independently separated from each other.

[0032] Among them, the main body shell 1 has an accommodating space 11 for installing the suction device 3 and the suction pipeline structure 4. The user can operate the breast pump to start the suction device 3 or stop the suction device 3. After the suction device 3 is connected to the adsorption cavity 23, the air in the adsorption cavity 23 is extracted to form a negative pressure state between the suction cup member 2 and the user's skin to implement adsorption, thereby realizing the adsorption function; after the suction device 3 is connected to the negative pressure cavity 12, the air in the negative pressure cavity 12 is sucked to deform the suction cup member 2 and implement suction on the user's breast to realize the milk suction function; under the suction action, the milk flows from the milk suction channel 24 into the milk storage cavity 13 for storage. After the suction is completed, the suction cup member 2 can be opened to take out the milk from the milk storage cavity 13 to realize the milk storage function.

[0033] The working principle and implementation method of this embodiment are as follows: When used for adsorption, the user brings the suction cup 2 close to the breast skin and fits it on the skin, so that the nipple extends into the milk suction channel 24. The suction cup 2 fits on the skin to form a closed space in the adsorption cavity 23. After the user turns on the suction device 3, the suction device 3 extracts the air in the adsorption cavity 23 through the suction pipeline structure 4 and forms a negative pressure state. Under the negative pressure state, the suction cup 2 can achieve a stable adsorption effect and avoid the situation of falling off and loosening in the early stage of adsorption.

[0034] When sucking milk, the user operates the breast pump to increase the suction force of the suction device 3. The suction device 3 extracts the air from the negative pressure chamber 12 through the suction pipeline structure 4, so that the negative pressure chamber 12 forms a negative pressure state. Under the negative pressure state, the suction cup component 2 can achieve a suction effect of a certain frequency or frequency, so that the milk flows from the breast through the nipple into the milk suction channel 24, and finally into the milk storage chamber 13 for storage. After the suction is completed, the user disassembles and opens the suction cup component 2 to take out the milk from the milk storage chamber 13, thereby realizing the milk storage function.

[0035] Furthermore, in some optional embodiments, the suction cup member 2 can be made of soft materials such as silicone, rubber, plastic, etc. Preferably, the suction cup member 2 is made of silicone material so that it can fit the user's body skin more easily. The breast shield is made of silicone material with good softness, elasticity and durability. The softness of the silicone material can fit the shape of the breast, reduce the pressure on the breast, and improve the comfort of the user. The elasticity of the silicone material can be appropriately adjusted according to the size of the breast to ensure a good sealing effect so as to effectively collect milk. Silicone is a non-toxic material that will not chemically react with breast milk, is easy to clean, can be sterilized at high temperature, and can withstand multiple washings and reuses without being easily damaged.

[0036] Furthermore, in some optional embodiments, the milk suction channel 24 has an inlet end 241 for communicating with the outside world and a valve end 242 for communicating with the milk storage chamber 13. The milk suction channel 24 is provided with a first elastic adsorption portion 21 for fitting the user's skin at a position close to the inlet end 241 for communicating with the outside world. The first elastic adsorption portion 21 opens toward the outside world from the inlet end 241. The first elastic adsorption portion 21 has a flexible adsorption surface for fitting the user's skin, and the flexible adsorption surface is smoothly intersected and connected with the milk suction channel 24.

[0037] Furthermore, in some optional embodiments, a hollow through-going second elastic adsorption portion 22 extends from the inner wall of the milk suction channel 24 toward the inlet end 241.

[0038] Furthermore, in some optional embodiments, the valve port 242 of the milk suction channel 24 for connecting to the milk storage chamber 13 has a one-way valve mouth 243 for preventing backflow. The one-way valve mouth 243 can adopt a duckbill valve structure. After the liquid flows from the milk suction channel 24 through the one-way valve mouth 243 into the milk storage chamber 13, the one-way valve mouth 243 blocks the backflow.

[0039] Furthermore, in some optional embodiments, an elastic deformation portion 6 for facilitating negative pressure suction is provided on one side of the milk suction channel 24 away from the inlet end 241 , and the negative pressure chamber 12 is located in a closed space between the elastic deformation portion 6 and the main housing 1 .

[0041] Furthermore, in some optional embodiments, the main housing 1 has a first suction channel 101 for connecting to the adsorption cavity 23 and a second suction channel 102 for connecting to the negative pressure cavity 12, the first suction channel 101 is located at a position of the main housing 1 close to the inlet end 241, the second suction channel 102 is located at a position of the main housing 1 away from the inlet end 241, and the suction cup member 2 is provided with a third suction channel 103 between the first suction channel 101 and the adsorption cavity 23 for connecting the two.

[0042] Further, in some optional embodiments, the suction device 3 includes an air pump 31 for suctioning air, a power supply 35 for powering, and a control unit 32 for controlling the suction device 3. The control unit 32 is an electronic device that facilitates the user to operate and use the breast pump. The control unit 32 includes a circuit module, an output and input module, a calculation module, and a user interaction module. The user interaction module has functional modules and function buttons that facilitate the user to control the start and stop, timing, power adjustment, and prompt sound adjustment of the breast pump.

[0043] Furthermore, in some optional embodiments, the suction pipeline structure 4 includes an air pipe 43 for air circuit connection and a solenoid valve group 412 for controlling the on-off of the air circuit, the solenoid valve group 412 includes a first solenoid valve 41 and a second solenoid valve 42, the first solenoid valve 41 is installed on the air circuit connection between the air pump 31 and the first suction channel 101, the second solenoid valve 42 is installed on the air circuit connection between the air pump 31 and the second suction channel 102, the control unit 32 is electrically connected to the air pump 31, the first solenoid valve 41 and the second solenoid valve 42, the control unit 32 includes a negative pressure sensor 33 for detecting air pressure, and the negative pressure sensor 33 is connected to the air circuit connection between the air pump 31 and the first suction channel 101.

[0044] Furthermore, in some optional embodiments, the suction pipeline structure 4 includes a diverter pipe 44 installed on the air pump 31. The diverter pipe 44 can be a three-way pipe or a four-way pipe. The diverter pipe 44 of this embodiment preferably adopts a three-way pipe. The second diverter port b of the diverter pipe 44 is connected to the first suction channel 101 through the air pipe 43, the third diverter port c of the diverter pipe 44 is connected to the air pump 31 through the air pipe 43, and the fourth diverter port d of the diverter pipe 44 is connected to the negative pressure sensor 33 through the air pipe 43.

[0045] Furthermore, in some optional embodiments, the suction cup member 2 has an annular buckling portion 25 for buckling and mounting on the main housing 1, and the annular buckling portion 25 extends toward the outside from a position close to the milk storage chamber 13 to facilitate disassembly and opening. The surface of the loose handle 5 has an anti-slip pattern 51 in a long strip structure, and a plurality of anti-slip patterns 51 are arranged at intervals from the position of the loose handle 5 close to the annular buckling portion 25 toward a direction away from the annular buckling portion 25. The anti-slip patterns 51 are respectively arranged on the front side e of the loose handle 5 close to the inlet end 241 and the back side f close to the outlet end, and the loose handle 5 adopts a semicircular or semi-elliptical thin-walled structure.

[0046] Furthermore, in some optional embodiments, the elastic deformation portion 6 adopts a suction bowl structure, and the elastic deformation portion 6 extends from the inner wall of the milk suction channel 24 toward the center of the channel to form a closed thin-walled curved surface structure, blocking the negative pressure chamber 12 and the milk suction channel 24 so that the two are not connected. The elastic deformation portion 6 has a concave structure and / or a convex structure alternately arranged from the outside to the inside, forming an axially reciprocating concave and convex corrugated curved surface profile. More specifically, the elastic deformation portion 6 has a first concave portion j, a second convex portion k, a third concave portion m, a fourth convex portion n and a fifth central concave bowl i that are connected in sequence from the inner wall of the milk suction channel 24 toward the center of the channel. The concave and convex corrugated structural design can enhance the flexible deformation of the elastic deformation portion 6, reduce the negative pressure force required for the elastic deformation, and increase the range and amplitude of the elastic deformation, which can better assist in sucking milk and facilitate user use.

[0047] Further, in some optional embodiments, the second elastic adsorption portion 22 has a reinforcing rib 221 near the adsorption cavity 23 for reducing the degree of compression and expansion deformation of the second elastic adsorption portion 22. The plurality of reinforcing ribs 221 are arranged at intervals around the circumference of the rotation axis of the second elastic adsorption portion 22. The reinforcing rib 221 extends from the position of the second elastic adsorption portion 22 near the center of the milk suction channel 24 toward a direction away from the center of the milk suction channel 24. The reinforcing rib 221 can adopt a straight extension structure or a curved extension structure. The reinforcing rib 221 of this embodiment preferably adopts a straight extension structure. With the straight line extending structure from the inside to the outside, when the flexible sealing surface of the second elastic adsorption part 22 is in contact with the user's skin, the force generated by the contact presses the second elastic adsorption part 22 and causes the second elastic adsorption part 22 to expand and deform toward the first elastic adsorption part 21, and the reinforcing ribs 221 generate a tightening force pulling in the opposite direction to resist the expansion deformation, so that the flexible sealing surface of the second elastic adsorption part 22 is more stably in contact with the user's skin, thereby ensuring the contact stability and sealing stability of the second elastic adsorption part 22, which is conducive to the smooth subsequent suction of lotion.

[0048] More specifically, the raised and spaced reinforcing ribs 221 can also prevent the second elastic adsorption portion 22 from being pressed and contacting the first elastic adsorption portion 21 during adsorption, causing the second elastic adsorption portion 22 to block the first suction channel 101 or the third suction channel 103, thereby ensuring that the air path for adsorption and suction is unobstructed.

[0049] Furthermore, in some optional embodiments, the host shell 1 of the present embodiment adopts a split structure, and the host shell 1 includes a host part and a shell part that are independent of each other. The host part is separated from the host shell 1 to form an independent assembly component, and the host part and the shell part can be assembled or separated by a detachable connection structure such as a plug-in connection, a slot connection, and a snap connection, wherein the host part includes a suction device 3 and a suction pipeline structure 4, and the host part has a host detachable shell for installing the suction device 3 and the suction pipeline structure 4, and the shell part includes a negative pressure chamber 12, a milk storage chamber 13 and an installation shell. The split structure design can facilitate the host part to replace the installation shell with different milk storage capacities, and can also facilitate the shell part to replace the suction device 3 with different suction power, thereby enriching the application variations of the breast pump, improving the detachable adaptability of the breast pump, and facilitating the user to purchase and use it.

[0050] Furthermore, in some optional embodiments, the suction device 3 of this embodiment may also eliminate the power supply 35 installed on the main housing 1, and the suction device 3 may be directly connected to an external power supply device or the power supply 35, i.e., an independent battery, an independent generator or AC power, through a power supply line.

[0051] Furthermore, in some optional embodiments, the host housing 1 of this embodiment can replace the user interaction module (or button) of the control unit 32 for user operation with an induction switch. The induction end of the induction switch is located near the surface of the host housing 1. The induction switch is electrically connected to the control unit 32. Several induction switches are respectively arranged at the positions of different operation buttons (such as the button position originally used for starting or shutting down, the button position originally used for adjusting the power, the button position originally used for using the adsorption effect, the button position originally used for using the milk suction effect, etc.). When the user's finger or skin contacts the induction trigger position of the corresponding function, the induction switch can transmit an open or closed signal to the control unit 32, avoiding the inconvenience of using a traditional push-button switch, avoiding discomfort caused by applying pressure on the skin using a push-button switch, and realizing that the corresponding function can be operated by lightly touching the surface of the host housing 1, which is convenient for users to use.

[0052] Furthermore, in some optional embodiments, the first elastic adsorption portion 21, the second elastic adsorption portion 22, the one-way valve nozzle 243, the release handle 5 and the elastic deformation portion 6 of the present embodiment are combined in an integrated manner to form a suction cup component 2. The suction cup component 2 can be disassembled and used as a whole, which simplifies the number of components to avoid the phenomenon of individual components being lost when the user disassembles the component. The integrated structure has better strength and does not require the user to disassemble and clean the scattered components and then reinstall them, which facilitates production installation and use disassembly.

[0053] Further, in some optional embodiments, such as Figure 3 and Figure 5As shown, the channel direction of the first suction channel 101 of this embodiment is toward the central axis of the milk suction channel 24, and the first suction channel 101 is close to a position where the adsorption cavity 23 has a larger space, thereby improving the adsorption efficiency.

[0054] Further, in some optional embodiments, such as Figure 8 As shown, the channel direction of the first suction channel 101 of this embodiment is toward the inlet end 241, and the first elastic adsorption part 21 has a ventilation extension groove for the first suction channel 101 to connect with the outside world. The ventilation extension groove can prevent the second elastic adsorption part 22 from blocking the first suction channel 101 when it is pressed into contact with the first elastic adsorption part 21, thereby ensuring that the air path for adsorption and suction is unobstructed.

[0055] Example 2 like Figure 1-3 as well as Figure 6 A wearable breast pump that is easy to adsorb is shown. The suction device 3 of the breast pump also includes a negative pressure tank 34 for auxiliary suction. The negative pressure tank 34 is connected to the first suction channel 101 and the air pump 31 through an air pipe 43. The negative pressure tank 34 is a hollow sealed tank body installed between the air pump 31 and the first suction channel 101. Before use, the air inside the negative pressure tank 34 can be evacuated in advance to form a negative pressure state. In the initial stage of adsorption, the breast pump can first evacuate the air in the adsorption cavity 23 through the negative pressure tank 34 before the air pump 31 is started to form a preliminary adsorption effect. The first solenoid valve 41 is installed on the air path connection between the air pump 31 and the negative pressure tank 34, and the second solenoid valve 42 is installed on the air pump 31. The air path between the second suction channel 102 is connected, and the first diversion port a of the diversion tube 44 is connected to the negative pressure tank 34. The control unit 32 can detect the suction effect of the negative pressure tank 34 through the negative pressure sensor 33, so that the negative pressure range of the adsorption cavity 23 is controlled between -2kPa and -25kPa, and the negative pressure state preferably meets -10kPa. When the negative pressure tank 34 extracts the air from the adsorption cavity 23 and still does not reach the preset negative pressure standard, the control unit 32 starts the air pump 31 to continue to suck the air from the adsorption cavity 23 to enhance the adsorption effect. The negative pressure tank 34 draws air in advance, which can reduce the workload of the air pump 31, speed up the adsorption efficiency, and improve the adsorption speed and adsorption stability.

[0056] The working principle of this embodiment: Before wearing, the air inside the negative pressure tank 34 is pumped out in advance by the air pump 31, and then the control unit 32 controls the first solenoid valve 41 and the second solenoid valve 42 to be closed, that is, the corresponding air path positions are disconnected, so that the negative pressure tank 34 and the air pipe 43 connected thereto form a closed negative pressure state inside; When wearing the breast milk mask, the user places the breast skin close to the inlet end 241 of the milk suction channel 24, and completely fits the flexible sealing curved surface of the second elastic adsorption part 22 on the user's skin so that the nipple passes through the inlet end 241 and extends into the milk suction channel 24. Then, the flexible adsorption curved surface of the first elastic adsorption part 21 is completely fitted on the user's skin, so that the adsorption cavity 23 forms a closed space. The control unit 32 controls the first solenoid valve 41 to open so that the pipeline between the negative pressure tank 34 and the adsorption cavity 23 is connected, that is, the corresponding air path positions are connected. The negative pressure tank 34 is connected to the adsorption cavity 23 through the air pipe 43 via the first suction channel 101 and the third suction channel 103. The negative pressure tank 34 sucks the air in the adsorption cavity 23 into itself, so that the user's skin is initially adsorbed before the air pump 31 is started, thereby achieving a pre-adsorption effect. During adsorption, since the negative pressure sensor 33 is connected to the air path between the negative pressure tank 34 and the adsorption cavity 23 through the air pipe 43 via the shunt pipe 44, the negative pressure sensor 33 detects the air path environment between the negative pressure tank 34 and the adsorption cavity 23 in real time. When the control unit 32 finds through the negative pressure sensor 33 that the air path between the negative pressure tank 34 and the adsorption cavity 23 does not reach the preset negative pressure state (preferably -10 kPa), the control unit 32 controls the air pump 31 to open and suck the air in the adsorption cavity 23, so that the negative pressure range of the adsorption cavity 23 is controlled between -2 kPa and -25 kPa, and the negative pressure state preferably satisfies -10 kPa, so as to enhance the adsorption force on the user's skin and achieve a stable adsorption effect of the breast pump on the user's skin; When sucking milk, the control unit 32 controls the second solenoid valve 42 to open so that the pipeline between the air pump 31 and the second suction channel 102 is connected. The air pump 31 not only extracts the air inside the adsorption cavity 23, but also simultaneously extracts the air inside the negative pressure cavity 12, so that the negative pressure cavity 12 forms a negative pressure state. The negative pressure state that satisfies the milk sucking effect preferably satisfies -60kPa (wherein, the negative pressure of the adsorption cavity 23 is -10kPa, and the negative pressure of the negative pressure cavity 12 is -50kPa). The negative pressure state causes the elastic deformation part 6 to be deformed toward the negative pressure cavity 12. The deformation of the elastic deformation part 6 causes the milk suction channel 24 to also form a negative pressure state. The negative pressure state causes the milk to flow out of the nipple and flow into the milk storage cavity 13 through the one-way valve nozzle 243 at the valve port end 242 through the milk suction channel 24, thereby achieving the suction and storage of the milk. After completing milk sucking, the user pinches the surface of the release handle 5 with fingers, and under the action of the anti-slip pattern 51 to increase the friction, pulls and flips open the suction cup 2 so that the snap-fit ​​portion 25 gradually separates from the main body shell 1, that is, the milk storage chamber 13 is connected to the outside world, so as to take out the milk stored in the milk storage chamber 13, and the user can open the suction cup 2 conveniently through the release handle 5.

[0057] Embodiment 3: like Figure 1 , Figure 2 and Figure 7 The wearable breast pump for easy adsorption shown in the embodiment is different from the embodiment 2 in that the accommodating space 11 is a closed space not connected to the outside or an independent sealing component (i.e., a detachable host part) independently and detachably mounted on the host housing 1, the air pump 31 is respectively connected to the first solenoid valve 41 and the second solenoid valve 42 through the shunt pipe 44, the first solenoid valve 41 and the first suction channel 101 do not need to be connected through the air pipe 43, and the second solenoid valve 42 is connected to the second suction channel 102 through the air pipe 43. After the host part is installed in the host housing 1, the accommodating space 11 is connected to the adsorption cavity 23 through the first suction channel 101, and the first solenoid valve 41 is opened to connect the air pump 31 to the accommodating space 11, and the air pump 31 can directly suck the air in the adsorption cavity 23 without the air pipe 43, thereby forming a preset negative pressure state.

[0058] The working principle of this embodiment: When wearing the breast milk chute 24, the user places the breast skin close to the inlet end 241 of the milk suction channel 24, and the flexible sealing curved surface of the second elastic suction part 22 is completely attached to the user's skin so that the nipple passes through the inlet end 241 and extends into the milk suction channel 24, and then the flexible suction curved surface of the first elastic suction part 21 is completely attached to the user's skin, so that the suction cavity 23 forms a closed space; During adsorption, the control unit 32 controls the first solenoid valve 41 to open so that the air pump 31 is connected to the closed accommodating space 11. Since the first suction channel 101 and the negative pressure sensor 33 are not connected to the air pipe 43 and are directly exposed to the accommodating space 11, the adsorption cavity 23 is naturally connected to the accommodating space 11. After the first solenoid valve 41 is opened, the air pump 31 is connected to the adsorption cavity 23 via the accommodating space 11, the first suction channel 101 and the third suction channel 103. The air pump 31 directly sucks the accommodating space 11 and the adsorption cavity 23. 3, the negative pressure sensor 33 directly detects the negative pressure state of the accommodating space 11 and can synchronously detect the negative pressure state of the adsorption cavity 23 because the accommodating space 11 and the adsorption cavity 23 are connected through the first suction channel 101 and the third suction channel 103. The control unit 32 controls the air pump 31 to suck until a negative pressure state is formed inside, and the negative pressure range is controlled between -5kPa and -20kPa, and the negative pressure state is preferably -10kPa, so as to enhance the adsorption force on the user's skin and achieve a stable adsorption effect of the breast pump on the user's skin; When sucking milk, the control unit 32 controls the second solenoid valve 42 to open so that the pipeline between the air pump 31 and the second suction channel 102 is connected. The air pump 31 not only extracts the air inside the adsorption cavity 23, but also simultaneously extracts the air inside the negative pressure cavity 12, so that the negative pressure cavity 12 forms a negative pressure state. The negative pressure state causes the elastic deformation part 6 to be deformed toward the negative pressure cavity 12. The deformation of the elastic deformation part 6 causes the milk suction channel 24 to also form a negative pressure state. The negative pressure state causes the milk to flow out of the nipple and flow into the milk storage cavity 13 through the one-way valve nozzle 243 at the valve port end 242 through the milk suction channel 24, thereby realizing the suction and storage of the milk. After completing milk sucking, the user pinches the surface of the release handle 5 with fingers, and under the action of the anti-slip pattern 51 to increase the friction, pulls and flips open the suction cup 2 so that the snap-fit ​​portion 25 gradually separates from the main body shell 1, that is, the milk storage chamber 13 is connected to the outside world, so as to take out the milk stored in the milk storage chamber 13, and the user can open the suction cup 2 conveniently through the release handle 5.
