Description

Technical Field

[0001] This utility model relates to the technical field of maternal and infant products, and in particular to a breast pump main unit. Background Technology

[0002] Existing electric breast pumps generally use push-button control, where users operate the pump with one or more single-point buttons. Traditional single-point buttons typically only support a single function, requiring multiple presses or combinations of button presses to complete complex function adjustments. For example, pressing the single-point button once can only achieve one of the functions: power on, power off, or mode switching. Alternatively, the power on, power off, or mode switching buttons may be set to different button combinations, which is inconvenient for users. In addition, due to the small size of breast pumps, a densely arranged design of multiple push-button control buttons results in too many elements on the outer surface of the breast pump, compromising the overall simplicity and aesthetics of the pump's appearance.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0034] like Figure 1As shown in Figure 11, this utility model provides a breast pump main unit 1, which is installed in a breast pump for use in controlling the operation of the breast pump for user breast pumping. Specifically, the breast pump main unit 1 includes a housing 11 and a control mechanism 12 disposed in the housing 11. The housing 11 has a mounting cavity 111, and the control mechanism 12 is disposed in the mounting cavity 111. The control mechanism 12 includes a first circuit board 121, a rocker control device 122 electrically connected to the first circuit board 121, and a display device 123. The rocker control device 122 triggers the first circuit board 121 to control the device status of the breast pump main unit 1, and the display device shows the status of the breast pump main unit 1. Device Status: In this embodiment, the breast pump main unit 1 uses the joystick control device 122 instead of the traditional push-button control. The user can control the breast pump main unit 1 by manipulating the joystick control device 122, thereby realizing the control of the breast pump. Compared with the traditional push-button control in existing breast pumps, the joystick control device 122 in this embodiment can achieve multi-directional control through single-point operation, which is convenient for users to operate, especially reducing the difficulty of one-handed operation. Moreover, while maintaining the small size of the breast pump product, the design layout of the outer surface of the breast pump main unit is simplified, avoiding too many design elements on the outer surface of the breast pump main unit, which would reduce the user's visual experience and improve the simplicity and aesthetics of the appearance of the breast pump product.

[0035] In practical applications, the device status of the breast pump host 1 includes at least the following: working mode status, power management status, operation control status, alarm status, silent mode status, and smart connection status.

It should be noted that the device status of the breast pump host 1 is consistent with the device status of the breast pump, and the above device statuses can be customized according to different needs; this embodiment does not impose specific limitations. Users can switch and adjust the different device statuses of the breast pump host 1 through the joystick control device 122 and visualize the different device statuses of the breast pump host 1 through the display device 123, allowing users to directly observe the device status of the breast pump host 1, thereby facilitating the use of the breast pump in daily life and optimizing the user experience. Optionally, the display device 123 may be a regular display screen or a display screen with human-computer interaction function.

[0036] In some alternative embodiments, the housing 11 includes a detachably connected front housing 101 and a rear housing 102, which together form the mounting cavity 111, and the control mechanism 12 is disposed between the front housing 101 and the rear housing 102, so as to facilitate the disassembly, assembly and maintenance of the control mechanism 12.

[0037] like Figure 2 , 3As shown in Figures 6 and 7, the joystick control device 122 includes a joystick switch 1221 electrically connected to the first circuit board 121 and a first joystick cap 1222 disposed outside the joystick switch 1221. At least a portion of the first joystick cap 1222 extends outside the housing 11. The joystick switch 1221 has a pivot point relative to the first circuit board 121. When the joystick switch 1221 is subjected to force, it rotates relative to the first circuit board 121 around the pivot point from a neutral position to an operating position, and drives the first joystick cap 1222 to move synchronously. In this embodiment, the first circuit board 121 is mounted in the mounting cavity 111 by a mounting bracket 16. The first circuit board 121 and the mounting bracket... 16. Detachable connection. Optionally, the connection method between the first circuit board 121 and the mounting bracket 16 includes, but is not limited to, snap-fit, plug-in, and threaded connection. One end of the first circuit board 121 is electrically connected to the rocker switch 1221, and there is a pivot point between the rocker switch 1221 and the first circuit board 121. The rocker switch 1221, when subjected to force, can rotate relative to the first circuit board 121 from a neutral position to an operating position around the pivot point. In this embodiment, the neutral position refers to the position where the rocker arm of the rocker switch 1221 is perpendicular to the first circuit board 121. In this embodiment, the operating position refers to the position where the rocker switch 1221 can trigger the first circuit board 121 to control the... The breast pump main unit 1 is configured to operate in different states. Multiple operating positions can be set according to different states. The rocker arm of the rocker switch 1221 rotates relative to the first circuit board 121 around the pivot point to switch between the neutral position and the operating position, thereby achieving multi-directional control of the rocker control device 122. The rotational movement of the rocker arm of the rocker switch 1221 around the pivot point includes at least 360° rotation and tilting. Optionally, the rocker switch 1221 can be a common miniature rocker switch. The first rocker cap 1222 is connected to the upper part of the rocker switch 1221, and at least part of the first rocker cap 1222 extends outside the housing 11 to allow for... The user operates the breast pump unit 1 for convenient use. Optionally, the bottom of the first rocker cap 1222 is provided with a first slot facing the rocker switch 1221, and at least part of the rocker switch 1221 is fixedly engaged in the first slot. In practical applications, the user can directly apply a rotational force to the first rocker cap 1222, and the rotational force applied by the user is transmitted to the rocker switch 1221 through the first rocker cap 1222, so as to drive the rocker arm of the rocker switch 1221 to rotate from the neutral position to the operating position relative to the first circuit board 121 around the pivot point, thereby triggering the first circuit board 121 to control the breast pump unit 1 to switch different device states.

[0038] On the other hand, the display device 123 can be configured as a backlit display device, specifically, such as Figure 3 As shown, the display device 123 includes a display housing 1231 disposed in the housing 11. The housing 11 has a first mounting opening 112 corresponding to the display housing 1231. At least a portion of the display housing 1231 is configured as a display lens 1233. The first circuit board 121 has a light-emitting module 1211 corresponding to the display lens 1233. In this embodiment, the display housing 1231 is disposed at the first mounting opening 112 in the housing 11. The outer wall surface of the display housing 1231 is exposed to the outside of the breast pump main unit 1 through the first mounting opening 112 for easy viewing by the user. The first circuit board 121 is disposed below the display housing 1231 and is arranged substantially parallel to the display housing 1231. At least a portion of the display housing 1231 directly opposite the light-emitting module 1211 is configured as a display lens 1233, so that the light emitted by the light-emitting module 1211 can directly illuminate the display lens 1233, allowing different functional patterns to be displayed on the display lens 1233, thereby visualizing the different device states of the breast pump host 1. Optionally, the display lens 1233 portion in the display housing 1231 can be made of a transparent and light-transmitting material.

[0039] In some alternative embodiments, in order to facilitate user operation and viewing of the device status of the breast pump host 1, the display housing 1231 is located near the top of the housing 11, and the corresponding first assembly port 112 is located opposite to the display housing 1231.

[0040] In some alternative embodiments, the display housing 1231 can be configured as a display lens 1233, and the display housing 1231 can be connected to the housing 11 by means of ultrasonic connection. This can help improve the installation accuracy and assembly efficiency of the display housing 1231, avoid damage to the display lens 1233 which would lead to a decrease in its optical performance, improve the stability of optical imaging, and improve the airtightness of the connection between the housing 11 and the display housing 1231, thereby improving the waterproof performance of the breast pump main unit 1.

[0041] Furthermore, such as Figure 4As shown, the display device 123 further includes a light-shielding bracket 1232. The light-shielding bracket 1232 is disposed between the display housing 1231 and the first circuit board 121. The light-shielding bracket 1232 is located between the display lens 1233 and the light-emitting module 1211. The light-shielding bracket 1232 has one or more light-transmitting openings 12321. The light-emitting module 1211 includes one or more light-emitting units corresponding to the light-transmitting openings 12321. The light emitted by the light-emitting units passes through... The light-transmitting opening 12321 illuminates the display lens 1233. In this embodiment, the light-shielding bracket 1232 preferably has several light-transmitting openings 12321 of different shapes. The light-emitting module 1211 includes several light-emitting units, and each light-emitting unit is correspondingly arranged with each light-transmitting opening 12321. The light emitted by the light-emitting module 1211 passes through the light-transmitting openings 12321 and illuminates the display lens 1233, enabling the display lens 1233 to display different functions. The patterns, specifically the functional patterns, include at least one or more of text, icons, and lines. These functional patterns are formed by the shape of a single light-transmitting opening 12321, or by a combination of the shapes of two or more light-transmitting openings 12321. In actual production, different functional patterns can be designed according to different device states of the breast pump body. This embodiment does not impose specific limitations. For example, the inner wall of any light-transmitting opening 12321 can be set as a Bluetooth pattern to achieve visualization during Bluetooth connection. Or, for example, several light-transmitting openings 12321 can be combined to form a digital pattern to achieve visualization of different adjustment states. In this embodiment, the light-shielding bracket 1232 itself has light-shielding properties. Light is transmitted through each light-transmitting opening 12321. By setting the light-shielding bracket 1232 between the display lens 1233 and the light-emitting module 1211, light leakage can be avoided, improving the stability and clarity of light imaging at the display lens 1233, thereby enhancing the visual aesthetics of the breast pump body 1.

[0042] In other alternative embodiments, such as Figure 4As shown, the rocker control device 122 further includes a connecting bracket 1223 disposed on one side of the light-shielding bracket 1232. The connecting bracket 1223 has a through hole 12231. The first rocker cap 1222 is disposed inside the through hole 12231 through a damping structure 1224. The damping structure 1224 allows the first rocker cap 1222 to be rotatably disposed in the connecting bracket 1223. While ensuring that the first rocker cap 1222 can rotate and the rocker switch 1221 can be used normally, the damping structure 1224 appropriately increases the rotational damping of the first rocker cap 1222, thereby improving the operating accuracy of the rocker switch 1221, protecting the rocker switch 1221, and extending the service life of the rocker control device 122.

[0043] Optional, such as Figure 4 As shown, the damping structure 1224 includes a damping connection portion 12240 disposed on the outside of the first rocker cap 1222. The damping connection portion 12240 includes a first connection end 12241 connected to the connection bracket 1223, a second connection end 12242 connected to the first rocker cap 1222, and an arc-shaped connection segment 12243 disposed between the first connection end 12241 and the second connection end 12242. The arc-shaped connection segment 12243 extends circumferentially along the first rocker cap 1222. The first connection end 12241 and the arc-shaped connection segment 12243 have a first preset angle and are in the same plane. The second connection end 12242 and the arc-shaped connection segment 12243 have a second preset angle and are perpendicular to the arc-shaped connection segment 12243. When the first rocker cap 1222... When the rocker arm cap 1222 is rotated from the neutral position to the operating position relative to the first circuit board 121 around the pivot point under force, the damping connection part 12240 undergoes a certain deformation process, which appropriately increases the rotational damping of the first rocker arm cap 1222, thereby improving the control accuracy of the rocker switch 1221. Furthermore, the damping connection part 12240, under its own elastic force, can drive the first rocker arm cap 1222 to return from the operating position to the neutral position, which is beneficial to improving the user experience. Preferably, there are two damping connection parts 12240, and the two damping connection parts 12240 are symmetrically arranged between the first rocker arm cap 1222 and the connecting bracket 1223. Further optionally, the damping connection part 12240 can be made of a material with a certain degree of elasticity to ensure the normal rotation of the first rocker arm cap 1222, thereby ensuring that the user can control the rocker switch 1221.

[0044] In some alternative embodiments, the light-shielding bracket 1232 and the connecting bracket 1223 can be set independently, allowing for flexible setting of the installation positions of the first rocker cap 1222 and the rocker switch 1221.

[0045] In some alternative embodiments, the light-shielding bracket 1232, the connecting bracket 1223, the first rocker cap 1222, and the damping structure 1224 are integrally formed to reduce the number of accessories and improve the assembly efficiency of the breast pump host 1.

[0046] In other alternative embodiments, such as Figure 3 , 6 As shown in Figure 7, the joystick control device 122 further includes a second joystick cap 1225 disposed outside the first joystick cap 1222. The second joystick cap 1225 is connected to the display housing 1231 or the housing 11, and the display housing 1231 or the housing 11 has a first opening 13 for the first joystick cap 1222 to pass through and rotate. At least a portion of the second joystick cap 1225 extends to the outside through the first opening 13. Further optionally, the second joystick cap 1225 is integrally molded from a flexible waterproof material to improve user operation. The second rocker cap 1225 is tightly connected to the display housing 1231 or the housing 11, and the second rocker cap 1225 is made of flexible waterproof material, which helps to seal the first opening 13 and prevent liquids and small debris from entering the breast pump main unit 1 through the first opening 13. In particular, it is waterproof, so as to protect the breast pump main unit 1. Moreover, the second rocker cap 1225 is connected to the top of the first rocker cap 1222, which helps to improve the user's comfort during operation and optimize the user experience.

[0047] like Figure 3 , 6As shown in Figure 7, the second joystick cap 1225 includes a driving part 12251, a connecting part 12252 disposed around the driving part 12251, and a swinging part 12253 disposed between the driving part 12251 and the connecting part 12252. The driving part 12251 is used for user operation, the connecting part 12252 is used for cooperating with the display housing 1231 or the housing 11, and the swinging part 12253 is used to drive the driving part 12251 to rotate relative to the display housing 1231 or the housing 11. In practical applications, the user can directly apply force to the driving part 12251 of the second joystick cap 1225, and drive the driving part 12251 to rotate relative to the display housing 1231 through the swinging part 12253, thereby driving the second joystick cap 12251 to rotate. A rocker arm cap 1222 moves synchronously, and drives the rocker switch 1221 to move synchronously through the first rocker arm cap 1222, so as to realize the user control of the rocker switch 1221; further optionally, the driving part 12251 is set corresponding to the top contour of the first rocker arm cap 1222, and the inner side of the driving part 12251 is provided with a second slot adapted to the top of the first rocker arm cap 1222. Preferably, the bottom of the driving part 12251 extends downward to increase the accommodating space of the second slot, thereby enhancing the connection stability between the second rocker arm cap 1225 and the first rocker arm cap 1222; the swing part 12253 includes an elastic connecting section disposed between the driving part 12251 and the connecting part 12252, and the elastic connecting section is preferably set as a downwardly recessed annular connecting section.

[0048] In some alternative embodiments, the second joystick cap 1225 is detachably connected to the display housing 1231 or the casing 11. The following description uses the detachable connection of the second joystick cap 1225 to the display housing 1231 as an example. Figure 7As shown, the connecting portion 12252 of the second rocker cap 1225 and the display housing 1231 are detachably connected via a snap-fit ​​structure. Specifically, the connecting portion 12252 includes a third slot 122521 located on the outer periphery of the second rocker cap 1225. The display housing 1231 is provided with a locking block 118 that matches the third slot 122521. The locking block 118 is located on the outer periphery of the first opening 13. During assembly, the locking block 118 engages with the third slot 122521. The connection is achieved by clamping the locking block 118 through the inner and outer side walls of the third slot 122521, so that the second rocker cap 1225 is tightly connected to the display housing 1231, and the driving part 12251 and the swing part 12253 of the second rocker cap 1225 are located inside the first opening 13, so that the driving part 12251 extends to the outside of the breast pump main unit 1 for user operation; optionally, the third slot 122521 extends toward one side of the second rocker cap 1225, and the third The extension direction of the slot 122521 can be along the axial direction of the second rocker cap 1225 or along the radial direction of the second rocker cap 1225 outwards. The locking block 118 can be set corresponding to the third slot 122521. The tight connection between the second rocker cap 1225 and the display housing 1231 helps to prevent external moisture or impurities from entering the breast pump main unit 1. Since the second rocker cap 1225 is made of a flexible waterproof material such as silicone, the breast pumping effect is further improved. The waterproof performance of the main unit 1 is improved; and installing the second rocker cap 1225 in the display housing 1231 can increase the compactness of the rocker control device 122 and optimize the aesthetics of the breast pump main unit 1. It should be noted that in actual production, the specific installation position of the second rocker cap 1225 can be set according to actual needs, such as installing the second rocker cap 1225 in the housing 11 or in the display housing 1231. This embodiment does not make specific limitations.

[0049] In some alternative embodiments, in order to further improve the connection stability between the first joystick cap 1222 and the second joystick cap 1225, thereby improving the user's control stability, the hardness of the first joystick cap 1222 is greater than the hardness of the second joystick cap 1225.

Figure 10 and Figure 11As shown, the night light device 14 includes a night light 141 and a lampshade 142. A second mounting opening 113 is provided in the housing 11, and the lampshade 142 is located at the second mounting opening 113. The night light 141 is located inside the lampshade 142. At least a portion of the lampshade 142 has a light-transmitting part 1421, which extends into the second mounting opening 113. The light-transmitting part 1421 is used to project the light emitted by the night light 141 out of the housing 11. 1. External; In this embodiment, the night light device 14 is disposed within the mounting cavity 111. A second mounting port 113 is provided at the bottom of the housing 11. The lampshade 142 is mounted at the second mounting port 113. At least the top of the lampshade 142 is configured as the light-transmitting part 1421. The light-transmitting part 1421 is exposed to the outside of the breast pump main unit 1 through the second mounting port 113, so that the light emitted by the night light 141 illuminates the breast pump main unit. External of the machine 1; To further enhance the aesthetics and simplicity of the breast pump body, the top surface of the light-transmitting part 1421 can be flush with the outer wall of the housing 11, that is, the light-transmitting part 1421 is neither recessed nor protruding relative to the outer wall of the housing 11. The specific installation of the lampshade 142 can be set according to actual needs, and this embodiment does not impose specific limitations; the lampshade 142 has a receiving cavity that opens to one side, and the night light 141 is installed in the receiving cavity; in addition, the night light 141 can use common lighting elements such as low-power LED beads; by setting the night light device 14 in the breast pump main unit 1, it is convenient for users to use the breast pump in dark environments, especially after the baby falls asleep at night. In order to protect the baby's sleep and good eye development, it is generally avoided to turn on bright lights. The breast pump main unit 1 with the night light device 14 can also serve as a suitable night light 141, which is convenient for users to use in bedrooms and other places.

[0051] In some alternative embodiments, the breast pump main unit 1 includes a plurality of night light devices 14, and the housing 11 is provided with a plurality of second mounting ports 113 to improve the lighting effect.

[0052] In some alternative embodiments, the lampshade 142 can be configured as a light-transmitting part 1421, made of a transparent light-transmitting material. During assembly, the lampshade 142 is connected to the housing 11 by ultrasonic connection, which helps to improve the installation accuracy and assembly efficiency of the lampshade 142, avoid damage to the light-transmitting part 1421 of the lampshade 142 which would lead to a decrease in its optical performance, improve the stability of optical imaging, and improve the airtightness of the connection between the housing 11 and the lampshade 142, thereby improving the waterproof performance of the breast pump main unit 1.

[0053] Furthermore, such as Figure 10 and Figure 11As shown, the night light device 14 also includes a fixing cover plate 143. The fixing cover plate 143 is located on the side of the lampshade 142 away from the light-transmitting part 1421 and is used to fix the night light 141. The fixing cover plate 143 has a second opening 1431 through which the power terminal 1411 of the night light 141 passes. The fixing cover plate 143 is fixedly connected to the side of the lampshade 142 away from the light-shielding part to detachably fix the night light 141 in the receiving cavity, which facilitates the maintenance and replacement of the night light 141. The power terminal 1411 of the night light 141 can be electrically connected to the first circuit board 121 through a wire, and the first circuit board 121 is used to power the night light 141. This also simplifies the internal circuit design of the breast pump host 1.

[0054] In some alternative embodiments, to further improve the convenience of using the breast pump, the breast pump main unit 1 is configured to be rechargeable, specifically, as shown in... Figure 8 and Figure 10 As shown, the control mechanism 12 further includes a second circuit board 124 and a charging port 125 electrically connected to the second circuit board 124. The second circuit board 124 is installed in the mounting cavity 111 and detachably connected to the housing 11. Optionally, the second circuit board 124 can be installed in the housing 11 by snap-fit, plug-in, threaded connection, or other means. The housing 11 has a third opening 114 corresponding to the charging port 125. The charging port 125 extends at least partially into the third opening 114. The charging port 125 faces the outside of the breast pump main unit 1 through the third opening 114 to facilitate electrical connection to a charging source for charging. The charging port 125 is clamped by the peripheral wall of the third opening 114 to improve the connection stability of the charging port 125. Optionally, the charging port 125 includes at least a Type-C port, a USB port, and a Lightning interface. Preferably, the charging port 125 is set as a Type-C port to adapt to existing universal chargers and improve the convenience for users to charge the breast pump main unit 1.

[0055] In other alternative embodiments, to improve the waterproof and dustproof performance of the breast pump main unit 1, such as... Figure 8 and Figure 10As shown, the housing 11 also has a mounting portion 115 located outside the third opening 114. The mounting portion 115 has a port cover 15 for sealing the third opening 114. The port cover 15 has a sealed state and an open state relative to the housing 11, corresponding to closing and opening the third opening 114, respectively. When the port cover 15 is in the sealed state, it closes the third opening 114, that is, it closes the charging port 125 to prevent small external impurities from entering the charging port. Port 125; when the port cover 15 is in the open state, the port cover 15 uncloses the third opening 114, and the third opening 114 is opened, that is, the port cover 15 uncloses the charging port 125, and the user can connect the charging port 125 to the charging source to realize charging; further optionally, the port cover 15 is integrally molded from a flexible waterproof material, for example, the port cover 15 is made of silicone or other materials, so as to further improve the waterproof and dustproof performance of the breast pump host 1.

[0056] In some optional embodiments, the port cover 15 can be installed relative to the mounting portion 115 in a mating connection or a rotating connection. For example, the mounting portion 115 includes a groove 1151 adapted to the port cover 15, and the port cover 15 is mated and connected in the groove 1151. Furthermore, a retaining pin 151 can be provided on one side of the port cover 15, and the mounting portion 115 also includes a retaining hole 1152 communicating with the groove 1151. The retaining pin 151 and the retaining hole 1152 engage to further improve the connection stability of the port cover 15. A limiting portion 152 is provided on the outer periphery of the retaining pin 151. Since the port cover 15 is made entirely of a flexible waterproof material such as silicone, when the port cover 15 is not subjected to external force, the limiting portion 152 restricts the... The retaining pin 151 disengages from the retaining hole 1152; when the port cover 15 is subjected to a corresponding external force, it can be removed relative to the groove 1151. During this process, the limiting part 152 is elastically deformed by the compression of the front shell 101 to ensure that the retaining pin 151 is detachably connected relative to the retaining hole 1152; based on the above-mentioned retaining structure, by inserting or pulling the port cover 15 into or out of the retaining hole 1152, the third opening 114 is switched to the sealed state or the open state; furthermore, the mounting part 115 may also include a relief groove 1153 located on one side of the groove 1151, at least part of the port cover 15 extends into the relief groove 1153, and there is a gap 150 between the port cover 15 and the inner wall of the relief groove 1153 to facilitate the user to remove the port cover 15.

[0057] In some alternative embodiments, the retaining pin 151 is rotatably connected within the retaining hole 1152, so that the port cover 15 is rotatably connected to the outside of the front housing 101. The user can directly rotate the port cover 15 to switch between the sealed and open states. Additionally, as... Figure 10 As shown, the limiting part 152 is disposed at a distance from the port cover 15. When the port cover 15 rotates relative to the front shell 101 to the groove 1151, the third opening 114 is in the open state. At this time, the limiting part 152 can restrict the locking shaft 151 from further disengaging from the locking hole 1152, so that the port cover 15 can still be hung on the outside of the front shell 101 to prevent the port cover 15 from being easily lost.
