Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and in particular to a heat-conducting structure of a piezoelectric ceramic pump and a breast pump. Background Technology

[0002] Piezoelectric ceramic pumps are a new type of micropump based on the inverse piezoelectric effect of piezoelectric ceramic materials. They have advantages such as small size, light weight, low power consumption, and no electromagnetic interference, and are widely used in medical devices, analytical instruments, microfluidic chips, and other fields. For example, in breast pumps, piezoelectric ceramic pumps are a core component, and their performance can greatly improve the efficiency of the breast pump and the user experience.

[0003] However, during operation, piezoelectric ceramic pumps inevitably generate heat due to internal friction and mechanical friction within the piezoelectric ceramic material. If this heat cannot be dissipated effectively and promptly, the pump's temperature will rise, affecting its performance and lifespan. Increased temperature reduces the piezoelectric coefficient of the ceramic material, thus decreasing the pump's output flow and pressure; prolonged operation at high temperatures also accelerates the aging of the ceramic material, shortening its service life.

[0004] Traditional piezoelectric ceramic pumps primarily rely on natural convection for heat dissipation, which has low efficiency and is insufficient for high-performance, long-term operation. Current improvements, such as adding heat sinks, also have limitations, including limited heat dissipation and complex structures, requiring further improvement and optimization.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:

[0021] Figure 1This is a cross-sectional view of the entire breast pump;

[0022] Figure 2 yes Figure 1 Enlarged view of a portion of point A in the middle. Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 2 As shown, this utility model discloses a heat-conducting structure for a piezoelectric ceramic pump, which aims to solve the problem of performance degradation and shortened lifespan caused by the heat generated during the operation of the piezoelectric ceramic pump.

[0025] The heat-conducting structure of this piezoelectric ceramic pump includes a housing 1 and a piezoelectric ceramic pump 2 located inside it. To effectively dissipate the heat generated by the piezoelectric ceramic pump 2, this invention designs a heat-conducting plate 3, which is fitted and tightly contacted with the surface of the piezoelectric ceramic pump 2 to ensure good heat conduction. The other side of the heat-conducting plate 3 is attached to the inner surface of the housing 1, thus forming an effective heat conduction path to transfer the heat generated by the piezoelectric ceramic pump 2 to the housing 1.

[0026] Preferably, the heat-conducting plate 3 is a metal plate made of a metal material with a high thermal conductivity, such as, but not limited to, copper, aluminum, or their alloys, to improve thermal conductivity.

[0027] More specifically, the connection between the heat-conducting plate 3, the outer casing 1, and the piezoelectric ceramic pump 2 is flexible and diverse, and can be either a permanent, non-removable method or a connection method that is easy to disassemble.

[0028] Specifically, the methods for fixing the heat-conducting plate 3 to the inner wall of the outer casing 1 include:

[0029] Non-removable methods: such as welding or bonding. These methods allow for tighter connections, improved thermal conductivity, and enhanced overall structural stability. Suitable for scenarios with low requirements for subsequent maintenance and disassembly.

[0030] Detachable design: such as snap-fit ​​or screw fixing. This method facilitates future disassembly, repair, and cleaning, making it easier for users to perform daily maintenance and extending the lifespan of the breast pump. Considering the hygiene requirements of breast pumps, this detachable design also makes it easier to thoroughly clean each component, preventing bacterial growth and ensuring breast milk safety. Due to its significant advantages, the detachable design is the preferred solution of this utility model.

[0031] Similarly, the connection between the heat-conducting plate 3 and the piezoelectric ceramic pump 2 also adopts the same flexible design, which can be selected according to the actual situation, such as welding, bonding or other non-removable methods, or snap-fit, screw fixing or other removable methods.

[0032] To further improve heat dissipation performance, the heat-conducting plate 3 is preferably designed as a perforated plate with a porous or honeycomb structure inside. This perforated design can significantly increase the heat dissipation area while reducing the weight of the heat-conducting plate 3, and facilitate the circulation of air inside the heat-conducting plate 3, thereby accelerating heat dissipation.

[0033] A more preferred approach is to allow gas to pass through the hollow structure of the heat-conducting plate 3, forming an efficient gas channel to accelerate air convection and speed up heat dissipation.

[0034] To more effectively utilize the gas discharged from the piezoelectric ceramic pump 2 for heat dissipation, this invention also includes an exhaust pipe 4. The exhaust port of the piezoelectric ceramic pump 2 is connected to the exhaust pipe 4, and the other end of the exhaust pipe 4 extends into and enters the hollow structure of the heat-conducting plate 3. In this way, the hot gas discharged from the piezoelectric ceramic pump 2 can directly enter the porous or honeycomb structure of the heat-conducting plate 3, accelerating airflow and thus more effectively removing heat.

[0035] In addition, the outer casing 1 has several heat dissipation holes 11 at the positions corresponding to the heat conduction plate 3. These heat dissipation holes 11 facilitate heat exchange between the outer casing 1 and the external environment, further enhancing the heat dissipation effect and preventing heat from accumulating inside the breast pump.

[0036] In order to maximize heat dissipation efficiency and ensure air circulation inside the breast pump, the area of ​​the heat dissipation holes 11 is larger than the area of ​​the corresponding side of the heat-conducting plate 3. This means that in addition to the hollow structure of the heat-conducting plate 3 and the heat dissipation holes 11, the inside of the outer shell 1 can also be directly connected to the outside through the part of the heat dissipation holes 11 that is not covered by the heat-conducting plate 3.

[0037] This design further enhances the overall heat dissipation capacity of the breast pump. Larger ventilation holes mean a larger air exchange area, allowing for more effective heat dissipation from inside the pump to the outside, preventing heat buildup. Simultaneously, this design also facilitates ventilation inside the pump, maintaining a dry and hygienic internal environment, inhibiting bacterial growth, thereby improving the user experience and the product's hygiene and safety.

[0038] More specifically, even in areas not fully covered by the heat-conducting plate 3, the heat dissipation holes 11 on the outer casing 1 can still function for heat dissipation and ventilation. This allows the breast pump to maintain stable performance even under high load conditions, avoiding malfunctions or discomfort caused by overheating.

[0039] In summary, the enlarged arrangement of the heat dissipation holes 11 is another optimization in the heat dissipation design of this utility model. Together with the hollow structure of the heat-conducting plate 3, the side wall design, and the exhaust pipe 4, it forms a highly efficient and reliable heat dissipation system, ensuring the long-term stable operation and hygiene safety of the breast pump, and providing users with a more comfortable and reassuring user experience.

[0040] like Figure 1 As shown, this utility model not only discloses an innovative piezoelectric ceramic pump heat conduction structure, but also further discloses a breast pump that uses this heat conduction structure. The breast pump integrates the aforementioned piezoelectric ceramic pump heat conduction structure on the breast pump body 5, including key components such as a heat conduction plate, an exhaust channel, and heat dissipation holes, which work together to effectively control the operating temperature of the piezoelectric ceramic pump.

[0041] Specifically, the heat-conducting plate 3 is tightly attached to the piezoelectric ceramic pump 2, rapidly absorbing the heat generated during its operation and evenly transferring it to the breast pump housing 1 through its high thermal conductivity. The heat dissipation holes 11 on the housing 1 further promote heat exchange with the external environment, preventing heat accumulation inside the breast pump. Furthermore, the exhaust pipe 4 of the piezoelectric ceramic pump 2 is cleverly connected to the perforated structure of the heat-conducting plate 3, utilizing the exhausted hot airflow to further enhance the heat dissipation effect of the heat-conducting plate, forming a highly efficient heat dissipation circulation system.

[0042] To further optimize heat dissipation and ensure efficient exhaust of waste heat, in the preferred embodiment, the heat-conducting plate 3 has an airtight sidewall, forming a relatively closed channel. This allows the hot air generated by the piezoelectric ceramic pump 2 (sent into the interior of the heat-conducting plate 3 through the exhaust pipe 4) to pass more smoothly through the perforated holes and heat dissipation holes 11 inside the heat-conducting plate 3, and finally be directly discharged to the outside, preventing the hot air from accumulating inside the outer shell 1 and affecting the performance and hygiene of the breast pump.

[0043] It should be noted that the sidewall of the heat-conducting plate 3 is not completely sealed. The sidewall is open at the interface between the inlet of the exhaust pipe 4 and the heat dissipation hole 11, so that hot air can enter and exit smoothly.

[0044] This integrated heat-conducting structure design brings multifaceted performance improvements to the breast pump:

[0045] Improved stability: Effectively controls the temperature of the piezoelectric ceramic pump to avoid performance degradation or malfunction due to overheating, ensuring stable operation of the breast pump during long-term use.

[0046] Extended lifespan: Lowering the operating temperature can slow down the aging of the piezoelectric ceramic pump and other related components, thereby extending the lifespan of the breast pump and reducing user costs.

[0047] Optimized user experience: Lower temperatures mean a more comfortable breastfeeding experience, avoiding discomfort caused by overheating. At the same time, a quieter operating environment and a more compact design also enhance the overall user experience.

[0048] Enhanced safety: Stable temperature control helps ensure the safety and reliability of the breast pumping process, providing greater peace of mind for breastfeeding.

[0049] By applying an advanced heat-conducting structure to the breast pump, this invention effectively solves the heat dissipation problem of piezoelectric ceramic pumps, providing users with a more comfortable, reliable, and convenient breast pumping experience.

[0050] Furthermore, it is worth noting that applying piezoelectric ceramic pumps to breast pumps offers numerous advantages, making them an ideal alternative to traditional motor-driven pumps:

[0051] Low-noise operation: The piezoelectric ceramic pump operates based on the vibration of piezoelectric ceramic materials, rather than the rotation of a motor, thus significantly reducing noise. This is especially important for breast pumps that require a quiet environment, creating a more comfortable experience for both mother and baby.

[0052] Compact size: The piezoelectric ceramic pump has a compact structure and small size, making it easy to integrate into the breast pump, making the breast pump lighter and more portable, and convenient for mothers to use anytime, anywhere.

[0053] Precise pressure control: Piezoelectric ceramic pumps can achieve more precise suction control, adjusting the suction strength and frequency according to the mother's needs, providing a more comfortable and personalized breastfeeding experience, and effectively protecting breast health.

[0054] Low power consumption and energy saving: Compared with traditional motor-driven pumps, piezoelectric ceramic pumps consume less power, are more energy-efficient and environmentally friendly, extend battery life, reduce charging frequency, and lower operating costs.

[0055] Long service life: Piezoelectric ceramic pumps have a simple structure and few wearing parts, thus having a longer service life, reducing the frequency of maintenance and replacement, and improving product reliability.

[0056] Hygiene and safety: The structural design of piezoelectric ceramic pumps is generally easier to clean and sterilize, which helps to maintain the hygiene of the breast pump and ensure the safety of breast milk.

[0057] This embodiment is only used to illustrate the technical solution of this utility model, and is not intended to limit it. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
