Description

Technical Field

[0001] The utility model relates to the technical field of atomizing devices, in particular to a shock-absorbing connecting component of an atomizer air pump. Background Art

[0002] A nebulizer, a device that atomizes test fluids, has a wide range of applications in the medical and industrial sectors. Nebulizers are typically used in medical or home settings. With technological advancements and increasing user demand, modern nebulizer design and manufacturing are increasingly focused on vibration and noise reduction.

[0003] During the continuous operation of the atomizer, its core component, the air pump, will operate at high speed and frequently. This high-intensity mechanical action will inevitably cause a certain degree of vibration in the entire machine. This vibration not only affects the working stability of the atomizer, but may also have an adverse impact on the surrounding environment and the user experience, such as generating noise interference or causing the platform where the atomizer is placed to shift slightly. In addition, the traditional connection between the air pump and the lower shell mostly relies on mechanical components such as springs or clips for fixed installation. Although these installation methods can achieve a stable assembly of the air pump to a certain extent, the operation process is relatively complicated and cumbersome, which not only increases the difficulty of assembly and disassembly, but also increases maintenance costs and time costs. At the same time, springs and clips are prone to loosening or damage when subjected to long-term stress, which in turn affects the working efficiency of the air pump and the overall performance of the atomizer.

DETAILED DESCRIPTION

Or, the paper can be used as a reference for definition. Of course, if the subsequent description defines the positional relationship between the two by mutual reference, this definition does not need to be included here.

[0026] A shock-absorbing connection assembly for an atomizer air pump is applied to an atomizer. The atomizer includes a housing, an air pump assembly 2, and a shock-absorbing connection assembly. The air pump assembly 2 and the shock-absorbing connection assembly are arranged in the housing. The housing includes an upper shell (not shown in the accompanying drawings) and a lower shell 1 connected together. The air pump assembly 2 drives the piston to move back and forth through the high-speed rotation of a brushless motor to generate air pressure. The shock-absorbing connection assembly is used to connect the housing of the atomizer and the air pump assembly 2.

[0027] The shock-absorbing connection assembly includes a mounting plate 3, an elastic connector 4 and a mounting seat 5. The air pump assembly 2 is fixed on the mounting plate 3. There are several mounting seats 5. The mounting seats 5 are arranged on the inner bottom surface of the outer shell. There is an accommodating space 501 inside the mounting seat 5. There are several elastic connectors 4. The number of the elastic connectors 4 corresponds one-to-one to the number of the mounting seats 5. The positions of the elastic connectors 4 correspond one-to-one to the positions of the mounting seats 5. One end of the elastic connector 4 is connected to the mounting plate 3, and the other end of the elastic connector 4 is inserted into the accommodating space 501 in the mounting seat 5. The accommodating space 501 is a cylindrical deep hole that matches the lower end of the elastic connector 4. The mounting seat 5 is used to position and fix the elastic connector 4, thereby realizing the installation and fixation of the air pump assembly 2 and ensuring the smooth operation of the air pump assembly 2.

[0028] As an embodiment of the present invention, the elastic connector 4 is an elastic structure. Specifically, the elastic connector 4 can be made of silicone or rubber material.

[0029] As an embodiment of the present utility model, the elastic connector 4 includes an upper connecting portion, a deformation supporting portion and a lower connecting portion, the upper connecting portion is connected to the mounting plate 3, and the lower connecting portion is inserted into the accommodating space 501 of the mounting seat 5, and the deformation supporting portion includes a contraction section 401, a throat 402 and an expansion section 403 arranged in sequence, and the diameter of the throat 402 is smaller than the diameter of the contraction section 401 and the diameter of the expansion section 403.

[0030] As an embodiment of the present invention, a mounting hole 301 is provided on the mounting plate 3, and the mounting hole 301, the elastic connector 4 and the mounting seat 5 are coaxially arranged. The upper connecting portion includes an annular groove 404, and the upper portion of the upper connecting portion can pass through the mounting hole 301, and the upper connecting portion is engaged with the mounting plate 3 through the annular groove 404. The annular groove 404 is arranged in the radial direction of the upper connecting portion, and the annular groove 404 is used to cooperate with the mounting hole 301, and the upper connecting portion forms an interlocking structure with the mounting plate 3. The hole wall of the mounting hole 301 is in an arc shape, and the thickness of the mounting plate 3 is greater than the axial groove depth of the annular groove 404. When the mounting plate 3 is engaged with the annular groove 404, it is fixed by the elastic force of the elastic connector 4. Specifically, the thickness of the mounting plate 3 is 3 mm, and the axial groove depth of the annular groove 404 is 1.5 mm.

[0031] As an embodiment of the present invention, the upper connecting portion further includes a guide section 405 disposed above the annular groove 404. The guide section 405 is truncated or conical in shape. The diameter of the mounting hole 301 is greater than the minimum diameter of the guide section 405, and the diameter of the mounting hole 301 is smaller than the maximum diameter of the guide section 405. The diameter of the end of the guide section 405 closer to the annular groove 404 is greater than the diameter of the end of the guide section 405 farther from the annular groove 404. The guide section 405 is used to guide the upper connecting portion through the mounting hole 301 and facilitate its insertion into the mounting hole 301. The portion of the mounting plate 3 adjacent to the mounting hole 301 is inserted into the annular groove 404, thereby achieving a secure connection between the elastic connector 4 and the mounting plate 3 and improving connection stability.

[0032] As an embodiment of the present utility model, in order to facilitate use, an extension section 406 is formed by extending from the guide section 405 in a direction away from the annular groove 404. The diameter of the extension section 406 is smaller than the diameter of the mounting hole 301. When in use, the extension section 406 first passes through the mounting hole 301. Due to the elasticity of the elastic connector 4, the guide section 405 is deformed in the process of passing through the mounting hole 301 until it completely passes through the mounting hole 301. After completely passing through the mounting hole 301, the guide section 405 loses external force restriction and restores its original shape. The mounting plate 3 around the mounting hole 301 is snapped into the annular groove 404 to form a stable connection structure.

[0033] As an embodiment of the present invention, the deformation support portion is in the shape of an 8, and the deformation support portion is the main support point of the entire elastic connector 4. The diameter of the contraction section 401 gradually decreases from the upper connection portion to the throat 402, and the diameter of the expansion section 403 gradually increases from the throat 402 to the lower connection portion. The diameter of the throat 402 is the smallest, and the triangular structure has high stability. The connection between the throat 402 and the contraction section 401 and the expansion section 403 is in the shape of an arc, and the arc is an inward concave arc in the axial direction, which enhances the strength of the entire elastic connector 4 and is not easy to collapse. During the vibration of the air pump assembly 2, the deformation support portion can be deformed to reduce the vibration force transmitted to the lower shell 1, thereby achieving the effect of shock absorption and noise reduction.

[0034] As an embodiment of the present invention, the radial angle between the contraction section 401 / expansion section 403 and the throat 402 is 45°, and the diameter of the throat 402 is 3-5 mm.

[0035] As an embodiment of the present invention, a plurality of exhaust grooves 408 are provided on a side of the expansion section 403 away from the throat portion 402 . The exhaust grooves 408 are used to exhaust the gas between the lower connecting portion and the mounting seat 5 .

[0036] As an embodiment of the present utility model, the area of ​​the surface where the upper connecting portion contacts the upper surface of the mounting plate 3 is smaller than the area of ​​the surface where the upper connecting portion contacts the lower surface of the mounting plate 3, and the maximum area of ​​the axial cross-section of the contraction section 401 is smaller than the maximum area of ​​the axial cross-section of the expansion section 403.

[0037] In one embodiment of the present invention, the lower connecting portion includes a connecting post 407, which is inserted into the accommodating space 501 of the mounting base 5 to securely connect the elastic connector 4 to the housing. Specifically, a certain gap is maintained between the outer circular wall of the connecting post 407 and the inner side wall of the mounting base 5 to facilitate installation and leave room for vibration. Preferably, the gap is 0.1 mm.

[0038] As an embodiment of the present invention, there are three mounting seats 5 distributed in a triangle, the number and position of the elastic connectors 4 correspond one-to-one with the mounting seats 5, and the number and position of the mounting holes 301 correspond one-to-one with the elastic connectors 4.

[0039] During installation, first, the plurality of elastic plug connectors 4 are fitted and fixed to the mounting plate 3 one by one, and then the plurality of elastic plug connectors 4 are inserted into the corresponding mounting seats 5 one by one.

[0040] The vibration-damping atomizer provided by the present invention uses a silicone or rubber elastic connector 4 to connect the air pump assembly 2 and the lower shell 1, thereby improving the vibration and noise reduction performance of the atomizer. Through the structure of the elastic connector 4, the conventional spring or buckle installation method is abandoned, which reduces cumbersome operations, improves the convenience of installation, and enhances the overall stability.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
