[0054] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to assist understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0055] In the related art, the air pump and the battery of the breast pump main unit are placed side by side, and the circuit board of the breast pump main unit is usually arranged above the air pump. To avoid the impact of the air pump vibration on the main board, a space for placing the main board needs to be separately provided at the top of the air pump, which leads to a relatively large volume of the breast pump main unit. However, a relatively large breast pump main unit is inconvenient to grip and operate during use by the user, resulting in a low user experience.

[0056] To solve the above technical problems, an embodiment of the present disclosure provides a breast pump main unit. The breast pump main unit includes a main board, a battery holder, and a driving component. The battery holder and the main board are stacked along a first direction, and the battery holder is connected to the main board. The side of the battery holder facing away from the main board has a receiving portion for receiving a battery; the driving component is arranged side by side with the battery holder along a second direction, and the driving component is communicatively connected to the main board to provide a suction force for sucking milk under the control of the main board; wherein, the first direction is perpendicular to the second direction. Through any embodiment of the present disclosure, the size of the breast pump main unit in the first direction can be reduced, thereby reducing the volume of the breast pump main unit, facilitating the user to grip and operate, and improving the user experience.

[0057] An embodiment of the present disclosure provides a breast pump main unit, as Figure 1 、 Figure 2 shown. The breast pump main unit includes a main board 1, a battery holder 2, and a driving component 3.

[0058] The battery holder 2 and the main board 1 are stacked along a first direction, and the battery holder 2 is connected to the main board 1. The side of the battery holder 2 facing away from the main board 1 has a receiving portion for receiving a battery 22; the driving component 3 is arranged side by side with the battery holder 2 along a second direction, and the driving component 3 is communicatively connected to the main board 1 to provide a suction force for sucking milk under the control of the main board 1; wherein, the first direction is perpendicular to the second direction.

[0059] According to the embodiment of the present disclosure, it should be noted that:

[0060] The first direction can be understood as Figure 1 the direction of the z-axis in the three-dimensional coordinate system (i.e., the height direction of the breast pump main unit), and the second direction can be understood as Figure 1 the direction of the y-axis in the three-dimensional coordinate system (i.e., the length direction of the breast pump main unit).

[0061] Regarding the position of the main board 1 relative to the driving component 3, taking Figure 1 as an example, the main board 1 can be entirely located on the left side of the driving component 3, or a part of it can be located on the left side of the driving component 3, and the other part can be located on the right side where the driving component 3 is located. For example, the part of the main electronic components on the main board 1 is arranged on the left side of the driving component 3, and the part of the electronic components for illumination on the main board 1 or the part for fixing the main board 1 is arranged on the right side.

[0062] The battery bracket 2 and the driving component 3 are arranged along the length direction of the breast pump main body, so that Figure 1 for example, the battery bracket 2 is located on the left side of the breast pump main body, and the driving component 3 is located on the right side of the breast pump main body.

[0063] The battery bracket 2 can be understood as a structure with a chamber inside, and the chamber inside it is the accommodating part for accommodating the battery 22. The accommodating part can accommodate a small part of the battery 22 or most of the battery 22. As Figure 1 shown, the accommodating part can roughly accommodate half of the volume of the battery 22. By setting the battery bracket 2 to accommodate a part of the battery 22 while the other part is exposed outside the accommodating part, when the breast pump main body is working, the heat generated by the battery 22 can be effectively dissipated through the part of the battery 22 exposed outside the accommodating part, avoiding the temperature of the battery 22 from being too high.

[0064] The battery bracket 2 and the main board 1 can be respectively provided with mutually adapted engaging structures to achieve connection, or the battery bracket 2 and the main board 1 can be indirectly connected through other connection structures. For example, a screw passes through the main board 1 and is connected to the battery bracket 2 to achieve the connection between the battery bracket 2 and the main board 1.

[0065] There can be various connection forms between the battery bracket 2 and the battery 22. For example, the battery 22 is directly clamped in the battery bracket 2, or the two are connected through adapted connection structures. For example, in one embodiment, a engaging part for engaging the battery 22 is provided on the side of the battery bracket 2 facing away from the main board 1. After the battery 22 is loaded into the accommodating part of the battery bracket 2, the engaging part is clamped on the battery 22. Among them, the engaging part can be a structure similar to a hook, which hooks on the side wall or edge of the battery 22. According to the embodiments of the present disclosure, the connection between the battery bracket 2 and the battery 22 can be strengthened, avoiding the battery 22 from shaking during the use of the breast pump main body.

[0066] The driving component 3 is a device that can generate suction force. It is communicatively connected to the main board 1. When the user operates the breast pump main body to work, the main board 1 transmits an electrical signal to the driving component 3, and the driving component 3 performs breast milk pumping according to the electrical signal instruction.

[0067] The driving component 3 can be arranged in contact with the battery bracket 2 or at an interval, and can be adjusted. A sound-absorbing cotton can also be provided between the driving component 3 and the battery bracket 2. On the one hand, it avoids the vibration of the driving component 3 being transmitted to the battery bracket 2, and on the other hand, it can eliminate the noise of the driving component 3.

[0068] The battery 22 is a device that provides electrical energy to the main board 1 and the driving component 3. It can be connected to the main board 1 and the driving component 3 respectively, or only connected to the main board 1. After voltage transformation, the main board 1 transfers the electrical energy to the driving component 3. The battery 22 and the main board 1 can be connected in a pluggable manner or in a fixed connection.

[0069] When applying the breast pump main unit, the battery 22 is installed in the accommodating part. The driving component 3 is connected to one end of the breast pump, and the other end of the breast pump is covered on the breast. With the user's operation of the main board 1, the main board 1 controls the driving component 3 to suck the gas in the other end of the breast pump, so that a negative pressure environment is formed in the other end of the breast pump. The milk sucked in the negative pressure environment flows into the milk storage tank of the breast pump to complete the breast milk sucking work.

[0070] According to an embodiment of the present disclosure, by arranging the main board 1, the battery holder 2 and the battery 22 in a row along the first direction, the size of the breast pump main unit in the first direction can be reduced, thereby reducing the volume of the breast pump main unit and facilitating the user's operation and grasping. By arranging the battery holder 2 between the battery 22 and the main board 1, it is possible to prevent the heat generated by the battery 22 from being directly transferred to the main board 1 and causing damage to the main board 1.

[0071] In one embodiment, as Figures 1 to 3 shown, the battery holder 2 is provided with heat dissipation holes 21 so that the heat generated by the battery 22 is dissipated from the inside of the accommodating part to the outside of the accommodating part through the heat dissipation holes 21.

[0072] According to an embodiment of the present disclosure, it should be noted that:

[0073] The setting position of the heat dissipation holes 21 can be adjusted. For example, the battery holder 2 has a top wall and a peripheral side wall, and the heat dissipation holes 21 can be provided on the top wall, or on the peripheral side wall, or part of them are provided on the top wall and the other part is provided on the peripheral side wall.

[0074] The number of the heat dissipation holes 21 can be one or multiple. For example, a larger-sized heat dissipation hole 21 is provided at the top of the battery holder 2, or multiple heat dissipation holes 21 arranged at intervals are provided at the top of the battery holder 2.

[0075] According to an embodiment of the present disclosure, by providing the heat dissipation holes 21, it is possible to prevent potential safety hazards caused by the overheating of the battery 22.

[0076] In one embodiment, as Figure 1 、 Figure 2 shown, the main board 1 is provided with a first hollow-out structure 11, and at least part of the driving component 3 passes through the first hollow-out structure 11 and is exposed; wherein, the first hollow-out structure 11 is located outside the area where the main board 1 and the battery holder 2 are stacked.

[0077] It can be understood that the main board 1 includes two parts. One part is located on one side of the battery holder 2, and the other part is located on one side of the drive assembly 3 and has a first hollow structure 11. Among them, the main board 1 located on one side of the battery holder 2 can be provided with the main control components of the breast pump host, and the main board 1 with the first hollow structure 11 can be provided with the execution components of the breast pump host, such as electronic components for illumination.

[0078] The first hollow structure 11 can be understood as an opening on a partial area of the main board 1 located on one side of the drive assembly 3. A part of the drive assembly 3 passes through the opening and protrudes from the plane where the main board 1 is located. For Figure 1 example, the upper half of the drive assembly 3 can pass through the first hollow structure 11 and extend out of the plane where the main board 1 is located. Among them, the size of the opening can be adapted to the size of a part of the drive assembly 3 or slightly larger than the size of a part of the drive assembly 3.

[0079] According to an embodiment of the present disclosure, the drive assembly 3 passes through the first hollow structure 11 of the main board 1, which can avoid separately providing a space for mounting the main board 1 at the top of the drive assembly 3, and further reduces the size of the breast pump host in the first direction. At the same time, setting the first hollow structure 11 to sleeved on the drive assembly 3 can further fix the main board 1 and improve the stability of the main board 1.

[0080] In one embodiment, as Figures 1 to 3 shown, the drive assembly 3 includes a package housing 31, and the package housing 31 is a stepped structure; wherein, a part of the package housing 31 passes through the first hollow structure 11, and the stepped surface 311 of the package housing 31 abuts against the main board 1.

[0081] The package housing 31 of the drive assembly 3 is a structure for loading the components in the drive assembly 3. By setting the package housing 31, the layout of the components can be further planned, and the space utilization rate can be improved.

[0082] For Figure 1 example, the package housing 31 can be understood as having a first section ( Figure 1 the upper part of the package housing 31 in Figure 1 ) and a second section (

[0083] Among them, the step structure can be a structure on one side of the packaging housing 31 or a structure on multiple sides.

[0084] In one embodiment, the size of the second section in the first direction is equal to the sum of the sizes of the battery holder 2 and the battery 22 in the first direction after the battery 22 is accommodated in the battery holder 2, so that the main board 1 on one side of the battery holder 2 and the main board 1 having the first hollow structure 11 are on the same plane.

[0085] According to an embodiment of the present disclosure, by providing the step structure, after the driving component 3 passes through the first hollow structure 11, it can abut against the step surface 311, further improving the stability of the main board 1.

[0086] In one embodiment, a sound-absorbing cotton is provided on the outer surface of the packaging housing 31 for absorbing the vibration and noise of the driving component 3.

[0087] In one embodiment, as Figures 1 to 3 shown, the driving component 3 further includes an air pump 32 and a solenoid valve group 33 provided in the packaging housing 31; wherein, the air pump 32 is located on one side of the packaging housing 31 close to the battery holder 2, and the solenoid valve group 33 is located on one side of the packaging housing 31 far from the battery holder 2; a first air inlet hole 321 is provided on the air pump 32, and the first air inlet hole 321 is located on the side of the air pump 32 far from the battery holder 2; and the first air inlet hole 321 extends in the second direction; an air outlet hole 331 is provided on the solenoid valve group 33, and the air outlet hole 331 is located at one end of the solenoid valve group 33 facing away from the battery holder 2, and the air outlet hole 331 extends in the third direction; the first air inlet hole 321 is communicated with the air outlet hole 331 through a pipeline, and the pipeline extends in the second direction, wherein the third direction is perpendicular to the first direction and the second direction in pairs.

[0088] According to an embodiment of the present disclosure, it should be noted that:

[0089] The third direction can be understood as Figure 1 the direction of the x-axis in the three-dimensional coordinate system in (i.e., the width direction of the breast pump main unit).

[0090] The driving component 3 further includes an air pump 32 and a solenoid valve group 33 inside the packaging housing 31. The air pump 32 can be understood as a structure for providing suction, and the solenoid valve group 33 can be understood as a structure for controlling the on / off of the suction between the air pump 32 and the breast pump. For example, when the solenoid valve group 33 is opened, the air pump 32 can suck the gas in the breast pump, and when the solenoid valve group 33 is closed, the air pump 32 cannot suck the gas in the breast pump. Their relative positions are Figure 3 illustrated by way of example, wherein, the first direction can be understood as Figure 3 the direction of the z-axis in the three-dimensional coordinate system in, and the second direction can be understood as Figure 3the direction of the y-axis in the three-dimensional coordinate system, and the third direction can be understood as Figure 3 the direction of the x-axis in the three-dimensional coordinate system. The air pump 32 is located on the left side of the encapsulation housing 31 (i.e., the side close to the battery bracket 2), and the solenoid valve group 33 is located on the right side of the encapsulation housing 31 (i.e., the side far from the battery bracket 2). The right side of the air pump 32 has a first air inlet hole 321, and the first air inlet hole 321 extends rightward. The right side of the solenoid valve group 33 has an air outlet hole 331, and the air outlet hole 331 extends downward. The first air inlet hole 321 and the air outlet hole 331 are connected through a pipeline, so that the distance between the air pump 32 and the solenoid valve group 33 can be reduced, the space utilization rate can be improved, and further the volume of the encapsulation housing 31 can be reduced.

[0091] According to the embodiments of the present disclosure, the space utilization rate inside the encapsulation housing 31 can be improved, and further the volume of the encapsulation housing 31 can be reduced.

[0092] In one embodiment, as Figure 3 shown, the driving assembly 3 further includes a motor. The motor is located above the solenoid valve group 33, that is, the motor and the air pump 32 form a similar "L" shape that is turned upside down, and the solenoid valve group 33 is located in the notch of the "L". The space utilization rate of the encapsulation housing 31 is further improved.

[0093] In one embodiment, as Figure 3 shown, the number of the air outlet holes 331 is one; the solenoid valve group 33 is further provided with a second air inlet hole 332 and a third air inlet hole 333. The second air inlet hole 332 and the third air inlet hole 333 are respectively communicated with the air outlet hole 331. The second air inlet hole 332 and the third air inlet hole 333 are respectively used for communicating with a breast pump; the solenoid valves of the solenoid valve group 33 are used to independently control the on-off of the second air inlet hole 332 and the third air inlet hole 333 with the air outlet hole 331.

[0094] The solenoid valve group 33 may have one solenoid valve, which has a second air inlet hole 332, a third air inlet hole 333 and an air outlet hole 331. It may also have two solenoid valves. One solenoid valve is provided with a second air inlet hole 332, and the other solenoid valve is provided with a third air inlet hole 333, but the air outlet ends of the two solenoid valves are integrated into one air outlet hole 331. Among them, the second air inlet hole 332 and the third air inlet hole 333 can be understood as extending along the second direction and both facing the Figure 3 right side (i.e., the direction away from the battery bracket 2). Among them, the second air inlet hole 332 and the third air inlet hole 333 are respectively used for connecting with a breast pump.

[0095] The solenoid valve group 33 can control the opening and closing of the second air inlet hole 332 and the third air inlet hole 333 separately, that is, the second air inlet hole 332 and the third air inlet hole 333 can be opened or closed at the same time, or when the second air inlet hole 332 is opened, the third air inlet hole 333 is closed (that is, opened alternately), so as to meet the user's various needs for single-sided milk suction and double-sided milk suction.

[0096] According to the embodiment of the present disclosure, the solenoid valve group 33 is provided with two air inlet holes, which can be connected to two breast pumps respectively to improve the efficiency of breast pumping. When the solenoid valve group 33 includes two solenoid valves, by providing an air outlet hole 331, the number of pipes connected to the air pump 32 can be reduced, thereby reducing the volume occupied and improving the space utilization.

[0097] In one embodiment, Figure 1 , Figure 2 , Figure 4 As shown, the breast pump host also includes a light shield 4, which is arranged on the side of the main board 1 away from the battery holder 2 and covers the main board 1, and the light shield 4 avoids the part of the driving component 3 exposed outside the first hollow structure 11; a light source 12 for emitting a light beam is arranged at the edge of the main board 1; and the light shield 4 is provided with a light-transmitting structure 41 for cooperating with the light source 12.

[0098] According to the embodiments of the present disclosure, it should be noted that:

[0099] The light shield 4 can be understood as a cover arranged on the top of the main board 1 (such as Figure 1 The light shield 4 may be a structure having a first hollow structure 11 and a second hollow structure 42. The light shield 4 may be a structure having a first hollow structure 11 and a second hollow structure 42 arranged on the first side of the main board 1. The light shield 4 may have a size that is consistent with the main board 1, or may be slightly larger than the main board 1. After the light shield 4 covers the main board 1, a cavity may be formed between the interior of the light shield 4 and the main board 1, and the cavity is used to accommodate the portion of the drive assembly 3 exposed outside the first hollow structure 11. Alternatively, in one embodiment, a second hollow structure 42 is provided on the light shield 4; the portion of the drive assembly 3 that passes through the first hollow structure 11 is embedded in the second hollow structure 42. The second hollow structure 42 may be understood as an opening in a partial area of ​​the light shield 4 located on one side of the drive assembly 3, and the drive assembly 3 is stuck in the opening after passing through the first hollow structure 11. Such a configuration may further fix the light shield 4, improve the stability of the light shield 4, and at the same time may reduce the distance between the light shield 4 and the main board 1, thereby reducing the size of the breast pump host in the first direction.

[0100] The light source 12 can be one or multiple. For example, in one embodiment, the light source 12 includes a plurality of light-emitting components spaced along the edge of the main board 1, the light-transmitting structure 41 includes a plurality of light-transmitting bands, and the plurality of light-transmitting bands correspond to the plurality of light-emitting components. Among them, each light-emitting component can correspond to only one light-transmitting band, or each light-emitting component can correspond to a plurality of adjacent light-transmitting bands. The on / off states of the plurality of light-emitting components can be adjusted, such as being turned on or off simultaneously, or a part being turned on and the other part being turned off. The specifications of the plurality of light-emitting components can be the same or different, for example, light-emitting components that can emit light beams of different colors can be provided. According to the embodiments of the present disclosure, different-shaped light patterns can be formed on the breast pump main body, improving the user's visual experience and providing illumination for the user when used at night.

[0101] The light-shielding cover 4 is a structure for blocking the transmission of light beams. The light-transmitting structure 41 on the light-shielding cover 4 can be understood as through holes, as Figure 4 shown, so that the light beams emitted by the light source 12 can only pass through the through holes and be projected onto the breast pump main body, avoiding the divergence of the light beams.

[0102] According to the embodiments of the present disclosure, by providing the light-transmitting structure 41 on the light-shielding cover 4, the divergence of the light beams can be restricted, enabling the light beams to be irradiated only at fixed positions on the breast pump main body, improving the visual experience, and providing illumination for the user when used at night.

[0103] In one embodiment, as Figure 1 、 Figure 2 shown, a first positioning hole 312 is provided on one side of the encapsulation housing 31 facing the light-shielding cover 4; a first positioning post 43 that cooperates with the first positioning hole 312 is provided on one side of the light-shielding cover 4 facing the encapsulation housing 31.

[0104] When the light-shielding cover 4 is covered on the encapsulation housing 31, the first positioning post 43 is inserted into the first positioning hole 312 to fix the light-shielding cover 4, preventing the light-shielding cover 4 from shaking in the breast pump main body.

[0105] In one embodiment, as Figure 1 、 Figure 2 shown, the main board 1 is provided with a second positioning hole 13, a second positioning post 44 is provided on one side of the light-shielding cover 4 facing the battery bracket 2, and a positioning portion 23 is provided on the battery bracket 2; the second positioning post 44 passes through the second positioning hole 13 and is connected to the positioning portion 23.

[0106] The positioning portion 23 may be a hole-shaped structure, that is, the second positioning column 44 passes through the second positioning hole 13 and is inserted into the hole-shaped structure of the positioning portion 23, thereby realizing the connection among the light shield 4, the main board 1 and the battery holder 2. Alternatively, the positioning portion 23 may be a structure having threads, the second positioning column 44 may be a cylindrical body, the second positioning column 44 may pass through the second positioning hole 13 and abut against the positioning portion 23, and the second positioning column 44 may be penetrated by a screw and connected with the thread of the positioning portion 23, thereby realizing the indirect connection among the light shield 4, the main board 1 and the battery holder 2, and further fixing the main board 1.

[0107] According to the embodiments of the present disclosure, the stability of the connection between the sunshade 4, the main board 1 and the battery holder 2 can be improved.

[0108] In one embodiment, Figure 1 , Figure 2 As shown, the breast pump host also includes a light guide 5, which includes a ring-shaped main body and a light guide protrusion arranged on the main body; wherein the main body is located on the side of the light shield 4 away from the main board 1 and surrounds the edge of the light shield 4, and the light guide protrusion is inserted into the light-transmitting structure 41.

[0109] It can be understood that the light guide member 5 includes two parts, one part is a ring member (i.e., the ring-shaped main body), and the other part is a protrusion protruding from the ring member (i.e., the light guide protrusion). Figure 1 For example, when the light guide 5 is connected with the light shield 4, the protrusion is inserted into the light-transmitting structure 41 from top to bottom, and the ring is against the top of the light shield 4. When the light source 12 is turned on, the light beam is transmitted through the light guide 5, passes through the protrusion and the ring in turn, and is projected onto the breast pump host.

[0110] According to the embodiments of the present disclosure, the divergence of the light beam can be avoided, and the user's experience at night can be improved. At the same time, the light guide protrusion of the light guide 5 is inserted into the light-transmitting structure 41, which can reduce the space occupied by the light guide 5 in the first direction, further reduce the size of the breast pump main unit in the first direction, and reduce the volume of the breast pump main unit.

[0111] In one embodiment, Figure 1 , Figure 2 As shown, the breast pump host further includes a first shell 6 and a second shell 7 , which are detachably connected and surround a space for accommodating the main board 1 , the battery holder 2 , the drive assembly 3 and the light shield 4 .

[0112] The first shell 6 and the second shell 7 can be respectively understood as Figure 1 The upper shell and the lower shell shown can be detachably connected via a snap-fit ​​structure, for example, the upper shell is provided with a snap hook, and the lower shell is provided with a snap groove that cooperates with the snap hook.

[0113] The upper housing may have an abutting structure protruding from its inner wall for abutting against the light shield 4. Similarly, the lower housing may have an abutting structure protruding from its inner wall for abutting against the battery 22, the battery holder 2, and the driving assembly 3, thereby improving its stability inside the breast pump main body.

[0114] According to an embodiment of the present disclosure, it is convenient to disassemble and assemble the breast pump main body, which is beneficial to the maintenance of the breast pump main body.

[0115] In one embodiment, the upper housing is provided with a light-transmitting area for allowing a light beam to pass through. The light-transmitting area is disposed opposite to the annular main body portion of the light guide member 5, so that the light beam of the light-emitting member sequentially passes through the light guide member 5 and the light-transmitting area and irradiates the external environment of the breast pump main body, facilitating lighting for the user and operating the breast pump main body.
