Description

Technical Field

[0001] This application relates to the field of air pump noise reduction technology, and in particular to a device for reducing the operating noise of a micro air pump by optimizing the fixed structure. Background Technology

[0002] Miniature air pumps are widely used in medical equipment, electronic cooling, and other fields, specifically in portable ventilators and analytical instruments. However, the vibration and noise they generate during operation negatively impact the user experience. Existing mounting methods are mostly rigid installations, which cannot effectively absorb vibration energy, causing noise to be amplified through the casing. Some noise reduction solutions use elastic materials to encase the air pump, but these suffer from poor heat dissipation, unstable installation, and maintenance difficulties. Therefore, there is an urgent need for a mounting device that balances noise reduction effectiveness, structural stability, and maintainability.

[0003] Patent CN202122931066.0 discloses a silicone sleeve, including a silicone ring (1). The upper and lower ends of the silicone ring (1) are respectively integrally formed with an elastic relief silicone tube (2) and an intermittent heat-insulating silicone tube (3). The elastic relief silicone tube (2) includes a silicone tube body (21). The lower end of the silicone tube body (21) is integrally formed with the silicone ring (1). The outer side wall of the silicone tube body (21) is uniformly integrally formed with an elastic relief groove (22). The upper end of the silicone tube body (21) is integrally formed with a limiting ring. The intermittent heat-insulating silicone tube (3) includes a silicone tube body (31), the outer wall of the silicone tube body (31) is uniformly integrally formed with a protruding strip (32), the inner wall of the elastic relief silicone tube (2) is uniformly integrally formed with a protruding support strip (5), and the inner wall of the intermittent heat-insulating silicone tube (3) is integrally formed with a chamfered silicone ring (6). The disadvantage of this solution is that the fully enclosed silicone sleeve completely seals the air pump, which hinders heat dissipation and easily leads to overheating of the micro air pump. Moreover, the installation is troublesome, the silicone sleeve needs to be forcibly inserted into the air pump, which can easily damage the components and is inconvenient to disassemble.

[0004] In summary, the existing technology has the following problems that urgently need to be solved: First, rigid installation (such as metal brackets) causes vibration energy to be directly transmitted to the equipment shell, amplifying the noise; Second, elastic wrapping solutions (such as fully enclosed silicone sleeves) hinder the air pump's heat dissipation, posing a risk of overheating; Third, installation and maintenance are difficult: traditional elastic sleeves need to be forcibly inserted into the air pump body, which can easily damage components and is inconvenient to disassemble. Utility Model Content

[0005] This application is made in view of the above and other ideas.

[0006] One of the purposes of this application is to provide a fixed structure that combines efficient noise reduction, optimized heat dissipation, convenient installation, and maintainability.

[0007] The objective of this utility model is achieved through the following solution:

[0008] A noise reduction device for fixing a miniature air pump includes a fixing unit and a connecting unit. The miniature air pump is installed in the fixing unit. The accommodating space of the fixing unit is used to accommodate a plurality of cylinders. The fixing unit includes a lower fixing part and an upper limiting part. The connecting unit is connected to at least both ends of the lower fixing part. The connecting unit includes a plurality of connecting members. The connecting members are provided with through holes. The connecting members include a first connecting body and a second connecting body. The through holes are provided on the second connecting body, and the thickness of the second connecting body is greater than the thickness of the first connecting body.

[0009] The objective of this application can also be further achieved through the following technical solutions:

[0010] In one embodiment, the lower fixing part includes a hollow area and a solid area, the solid area being disposed at both ends of the hollow area, and the solid area including a first solid component and a second solid component.

[0011] In one embodiment, the fixing unit and the connecting unit are integrally molded silicone bodies.

[0012] In one embodiment, the hardness of the fixing unit is greater than the hardness of the connecting unit.

[0013] In one embodiment, the first entity and the second entity are symmetrically arranged about the centerline of the upper limiting portion, and both the first entity and the second entity include an end face and a cylindrical surface.

[0014] In one embodiment, the upper limiting portion has greater flexibility than the lower fixing portion.

[0015] In one embodiment, the connecting unit includes four connectors, which are disposed at the four corners of the fixing unit and are connected to the end face and the cylindrical surface.

[0016] In one embodiment, an arc segment is provided on the end face, the arc segment being an empty space for the air inlet and outlet of the micro air pump.

[0017] In one embodiment, the hollowed-out area is triangular, frustum-shaped, or rectangular on the side.

[0018] In one embodiment, the volume of the upper limiting portion is larger than the volume between the first entity and the second entity; the upper limiting portion is strip-shaped.

[0019] In one embodiment, a positioning post is provided on the housing, and the through hole passes through the positioning post to fix the connector.

[0020] In one embodiment, the air pump interface is aligned with the arc segment of the end face, and the hollowed-out area (side triangle) promotes heat dissipation.

[0021] In one embodiment, the hollowed-out design of the hollowed-out area cuts off the vibration transmission path.

[0022] In one embodiment, the first physical component and the second physical component are symmetrically distributed to evenly distribute the vibration load.

[0023] In one embodiment, the hollowed-out area occupies the main body of the fixed part, forming a natural air channel to accelerate heat dissipation.

[0024] In one embodiment, the hollowed-out area occupies 30% to 80% of the main body of the lower fixing part.

[0025] In one embodiment, the four connectors are distributed at the four corners of the fixing unit to improve installation stability.

[0026] In one embodiment, one end of the connector is connected only to the end faces of the first and second physical components, and the connection method is a fixed connection. The connector and the fixing unit are integrally formed. Furthermore, the other end of the connector is connected to the outer shell.

[0027] In one embodiment, the connecting unit and the fixing unit are detachably connected, and the connecting unit is a circumferential silicone piece fitted onto the two end faces of the fixing unit.

[0028] Compared with the prior art, the advantages of the technical solution of this application include at least the following:

[0029] 1. Unlike existing technologies, this application designs a vibration path blocking mechanism. The lower fixing part adopts a large-area hollow area in the middle (accounting for 30%-80%) to physically cut off the vibration wave transmission path. The upper limiting part ensures that the air pump is fixed in the fixing unit and also facilitates the installation of the air pump. At the same time, the first and second solid parts are symmetrically distributed about the center line to evenly distribute the vibration load and avoid local stress concentration. On the other hand, the connecting part and the fixing unit are integrally molded silicone bodies, which absorb high-frequency vibration through material elasticity, or use a detachable method to wrap the two ends of the fixing unit with a circumferential silicone kit to form a secondary vibration damping layer.

[0030] 2. Unlike existing technologies, the hollowed-out area of ​​this application forms a through-flow airflow channel (the side is triangular / frustum / rectangular), which accelerates air convection and heat dissipation and maximizes the heat dissipation area of ​​the heat sink. Secondly, the end face of the solid part is provided with an arc segment with an open structure to ensure that the air pump inlet / outlet is fully exposed and to prevent airflow blockage. Thirdly, only the solid areas at both ends contact the air pump, reducing the heat conduction area.

[0031] 3. Unlike existing technologies, this application utilizes four corner positioning connectors: four connectors are distributed at the four corners of the fixed unit and are inserted into the positioning post of the outer shell through through holes to achieve millimeter-level precise positioning. On the other hand, during disassembly, it is only necessary to separate the connectors from the positioning post (or remove the silicone sleeve), without touching the air pump body, thus avoiding component damage caused by hard plugging / pulling in traditional solutions.

[0032] 4. Unlike existing technologies, this design achieves a breakthrough in noise reduction, heat dissipation, and easy maintenance for the first time in the field of micro air pump fixing through a triple innovation of hollow vibration damping structure, local contact heat dissipation, and modular connection, providing quiet and reliable core component support for medical / electronic equipment.

Detailed Implementation

[0044] The details of one or more embodiments of this application will be set forth in the following description of the accompanying drawings and specific embodiments. Other features, objects, and advantages of this application will become clear from these descriptions, drawings, and claims.

[0045] It should be understood that the phrases and terms used in this document are for descriptive purposes and should not be considered restrictive. The use of “including,” “contains,” or “has,” and their variations, in this document is intended to include, in an open-ended manner, the items listed thereafter, their equivalents, and any additional items.

[0046] The present application will now be described in more detail with reference to various embodiments and examples of several aspects thereof. Example 1

[0047] The present invention relates to a noise reduction device for fixing a micro air pump (4) in an air pump controller for a sleep pillow, as shown in Figures 1-3 according to an embodiment of the present application. The device includes a fixing unit (1) and a connecting unit (2). The micro air pump (4) is installed in the fixing unit (1). The accommodating space of the fixing unit (1) is for two cylinders. The fixing unit (1) includes a lower fixing part (11) and an upper limiting part (12). The connecting unit (2) is connected to at least both ends of the lower fixing part (11). The connecting unit (2) includes four connectors (21). The connectors (21) are provided with through holes (211). The connectors (21) include a first connector (212) and a second connector (213). The through holes (211) are provided on the second connector (213), and the thickness of the second connector (213) is greater than the thickness of the first connector (212).

[0048] The objective of this application can also be further achieved through the following technical solutions:

[0049] In this first embodiment, the lower fixing part (11) includes a hollow area (111) and a solid area (112). The solid area (112) is disposed at both ends of the hollow area (111), and the solid area (112) includes a first solid component (113) and a second solid component (114), as shown below. Figure 1 As shown.

[0050] In this first embodiment, the first connector (212) is strip-shaped or strip-shaped, and the second connector (213) is circular or arc-shaped.

[0051] In this first embodiment, the thickness of the first connector (212) is less than the thickness of the second connector (213), which makes it easier for the second connector (213) to be stretched under force, preventing the air pump from being affected by gravity and falling too low to contact the outer shell. It also helps to minimize the vibration generated when the air pump is working.

[0052] In this first embodiment, the thickness of the second connector (213) is greater than the thickness of the first connector (212). The localized thickening of the second connector (213) increases strength and reliability, reduces damage and scrapping during installation, and lowers the scrap rate. Figure 3 As shown.

[0053] In this first embodiment, the fixing unit (1) and the connecting unit (2) are integrally formed silicone bodies.

[0054] In this first embodiment, the inner diameter of the first solid part (113) is larger than that of the second solid part (114), and there is a step on the main body of the micro air pump (4), while the step is fastened to the upper limiting part (12).

[0055] In this first embodiment, both the first solid component (113) and the second solid component (114) include an end face (115) and a cylindrical surface (116), as shown below. Figure 4 As shown.

[0056] In this first embodiment, the connecting unit (2) includes four connectors (21), which are located at the four corners of the fixing unit (1), and the connectors (21) are connected to the end face (115) and the cylindrical surface (116).

[0057] In this first embodiment, an arc segment (1151) is provided on the end face (115) of the first solid part (113), and the arc segment (1151) leaves the air inlet and outlet of the micro air pump (4) empty.

[0058] In this first embodiment, the hollow area (111) is triangular or arrow-shaped on the side, and the top of the hollow area (111) is rounded.

[0059] In this first embodiment, the inner diameter of the upper limiting part (12) is larger than the inner diameter of the first solid part (113) / second solid part (114); the upper limiting part (12) is strip-shaped.

[0060] In this first embodiment, a positioning post (31) is provided on the outer shell (3). The through hole (211) passes through the positioning post (31) to fix the connector (21). When the through hole (211) is fixed on the positioning post (31), the positioning post (31) is 2-4 mm higher than the through hole. When all connectors (21) are fixed on the positioning post (31), the connectors (21) are in a stretched state.

[0061] In this first embodiment, the spacing between adjacent positioning posts (31) is greater than the spacing between adjacent through holes (211) in the natural state, so the connector (21) will inevitably be stretched.

[0062] In this first embodiment, the outer shell (3) includes a lower shell and an upper shell. The positioning post (31) is fixed to the lower shell. The positioning post (31) is 2-4 mm higher than the through hole, which facilitates the connection between the upper shell and the positioning post (31).

[0063] In this first embodiment, the air pump (4) interface is aligned with the arc segment (1151) of the end face (115), and the hollow area (111) (side triangle) promotes heat dissipation.

[0064] In this first embodiment, the hollow design of the hollow area (111) cuts off the vibration transmission path.

[0065] In this first embodiment, the first solid component (113) and the second solid component (114) are symmetrically distributed to evenly distribute the vibration load.

[0066] In this first embodiment, the hollow area (111) occupies the main body of the fixed part (11), forming a natural air channel to accelerate heat dissipation.

[0067] In this first embodiment, the hollowed-out area (111) occupies 30% to 80% of the main body of the lower fixing part (11).

[0068] In this first embodiment, the four connectors (21) are distributed at the four corners of the fixing unit (1) to improve installation stability, such as Figure 4 As shown. Example 2

The connecting unit (2) includes a plurality of connecting members (21). The connecting members (21) are provided with through holes (211).

[0071] In this second embodiment, the outer diameter of the position where the solid region (112) of the lower fixing part (11) connects with the upper limiting part (12) is larger than the outer diameter of the position above the solid region (112) of the lower fixing part (11) where there is no connection.
