Description

Sealed micro-grid atomization module device

Technical field

The invention relates to the field of electronic atomization devices, and in particular to a sealed micro-grid atomization module device.

Background technique

At present, the principle of nebulizer treatment on the market is to atomize the drug into tiny droplets, and then inhale these droplets through the nose to achieve the therapeutic effect. This not only reduces the pain of taking medicine, but also reduces the waste of drugs, and can make the efficacy of the drug to the extreme. The nebulizer is medically anti-inflammatory, antitussive, expectorant, relieves bronchospasm, smoothes the airway, and improves ventilation function, so that the patient does not feel difficulty breathing. At the same time, it is also possible to prevent respiratory infections before and after chest surgery, resulting in good results in surgery, even in the treatment of lung cancer with anticancer drugs. Nowadays, the assembly and disassembly of the atomizing sheet in the atomizer are troublesome, and there is a defect of poor versatility. When applied, the micro-mesh atomizer is an important component of the micro-mesh atomizer. It is made of metal mesh and ceramic material. It is driven by a certain frequency of the circuit to make the ceramic vibrating piece vibrate and oscillate. The metal mesh oscillates at high speed, so that the liquid passes through many tiny meshes on the metal mesh and is quickly ejected, forming numerous tiny atomized particles. However, the atomized sheets on the market usually need to be purchased separately, and a series of problems such as clamping and fixing, sealing and waterproofing, and circuit welding are encountered during assembly, which greatly affects the versatility of the use of the atomizing sheets; The required structure is complex, resulting in increased costs.

Summary of the invention

In view of the above problems, an object of the present invention is to provide a sealed microgrid atomization module device which can improve the versatility of use of an atomized sheet, and which has a simple structure and a low cost.

In order to achieve the above object, the present invention provides a sealed microgrid atomization module device, which comprises an upper casing, a lower casing closedly connected to the upper casing, and a sequence between the upper casing and the lower casing. A first sealing ring, a micro-mesh atomizing sheet and a second sealing ring are provided. The upper casing is provided with two intermediate passage fixing columns which respectively extend outward and communicate with the interior. The middle pass fixing post is provided with a metal contact that passes through the intermediate pass fixing post. The microwire atomizing sheet is provided with a wire connected to the metal contact.

In some embodiments, the upper casing includes a cover plate, a first perforation as a spray opening of the atomization piece on the center of the cover plate, an annular protrusion provided on an inner side edge of the cover plate, and an annular protrusion on the inner side edge of the cover plate. The inner cover plate is provided with a plurality of annular arc-shaped limiting blocks.

In some embodiments, a limit post is provided on the cover.

In some embodiments, the lower case includes a receiving case sealed with the cover plate, a second perforation provided at a bottom portion of the receiving case as a contact portion between the chemical liquid and the atomizing sheet, and a circular arc limit at the bottom of the receiving case. The limit slot corresponding to the bit block.

In some embodiments, the metal contacts are metal posts or metal spring probes.

The invention has the beneficial effects of improving the versatility of the use of the atomized sheet, and having the advantages of simple structure and low cost. Since the upper and lower casings of the atomizing sheet and the first sealing ring and the second sealing ring are integrally packaged, they are then connected to the outside through metal contacts connected to the atomizing sheet. In the prior art, a series of problems such as clamping, sealing, waterproofing, circuit welding, etc. are encountered during assembly, and the atomizing sheet and its components are modularized, and the versatility of the atomizing sheet is improved; The housings are only fixed by ultrasonic line ultrasonic welding, which solves the problem that the structure required for assembling the atomized sheets is complicated and causes an increase in cost. The utility model can improve the versatility of the use of the atomized sheet, and has the advantages of simple structure and low cost.

detailed description

The invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1-4, a sealed microgrid atomization module device includes an upper casing 01, a lower casing 02 closedly connected to the upper casing 01, and upper casing 01 and lower casing 02. The first sealing ring 03, the micro-mesh atomizing sheet 04 and the second sealing ring 05 are sequentially disposed. The upper casing 01 is provided with two intermediate passage fixing posts 06 which extend outwardly and communicate with the interior. A metal contact 07 passing through the intermediate fixing post 06 is disposed on the intermediate fixing post 06. The microwire atomizing sheet 04 is provided with a wire connected to the metal contact 07. When the upper casing 01 and the lower casing 02 are ultrasonically welded by the annular protrusion, the limiting protrusion is fixed in the limiting groove and the first sealing ring 03 and the second sealing ring are assembled. The extrusion deformation is generated such that the upper casing 01, the first seal ring 03, the micro-mesh atomizing sheet 04, the second seal ring 05, and the lower casing 02 are sequentially fixedly connected to form a sealed closed state. The upper casing 01 includes a cover plate 11, a first perforation 12 as a spray port of the micro-mesh atomization piece 04, and an annular protrusion 13 provided on the inner side edge of the cover plate 11 on the center of the cover plate 11, and A plurality of annular arc-shaped limiting blocks 14 are arranged on the cover 11 on the inner side of the annular projection 13. A limit post 15 is disposed on the cover plate 11. The annular projection 13 serves as an ultrasonic line. The lower casing 02 includes a accommodating case 21 sealed to the cover plate 11, a second through hole 22 at a bottom portion of the accommodating case 21 as a contact portion between the medicinal liquid and the micromesh atomizing sheet 04, and a circle at the bottom of the accommodating case 21. The arc limiting block 14 corresponds to the limiting slot 23 . The metal contact 07 is a metal post or a metal spring probe.

When the upper casing 01 and the lower casing 02 are ultrasonically welded by the annular protrusions 13 , the limiting protrusions are fixed in the limiting groove 23 and the first sealing ring 03 and the second sealing ring 05 are deformed by extrusion. Thus, the upper casing 01, the first seal ring 03, the micro-mesh atomizing sheet 04, the second seal ring 05, and the lower casing 02 are sequentially fixedly connected to form a sealed closed state. The micro-mesh atomizing sheet 04 is connected to one end of the metal contact 07 through a wire in the sealed chamber, and the other end of the metal contact 07 is exposed to the outer surface of the housing for external driving circuit. Medical grade silica gel is required because the seal needs to be deformed and will be in direct contact with the liquid. In order to prevent the spray opening of the micro-mesh atomizing sheet 04 from being blocked, and the contact area of the micro-mesh atomized sheet and the chemical liquid is larger, the inner diameter of the first sealing ring 03 in this embodiment should be smaller than the inner diameter of the first perforating 12, The inner diameter of the second seal ring 05 should be smaller than the inner diameter of the second through hole 22.

What has been described above is only some embodiments of the invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the inventive concept.
