Technical Field

[0001] The utility model relates to the field of nitrogen blowing concentration, and particularly relates to a dual-mode quick-release air blowing structure. Background Art

[0002] Generally, there are two common types of nitrogen blowers on the market, the direct blowing form and the inclined blowing form. Usually, these two forms are independent and generally do not appear on one instrument. In the direct blowing form, the air blowing needle opening is at the center of the test tube, while in the inclined blowing mode, it is on the side of the test tube; the air flow forms are also different.

[0003] The traditional forms are independent and have different design methods, making it difficult to achieve perfect compatibility. To achieve compatibility between the two forms, it is necessary to consider their interchangeability. And for easy replacement, the flow path seal must be disassembled to form a fixed part and a replaceable part, which increases the difficulty of sealing. When designing, the parallelism requirement of the instrument also needs to be ensured. Summary of the Utility Model

[0028] Embodiment 1

[0029] As Figures 1 to 6 shown, the present utility model provides a technical solution:

[0030] A dual-mode quick-release air blowing structure, which at least includes but is not limited to an air blowing module fixing plate 1 and an air blowing assembly 2; the air blowing assembly 2 is provided with a magnetic attraction part, a sealing part and an air conveying part; the air blowing module fixing plate 1 is provided with a limiting part for limiting the air blowing assembly 2 and a matching hole 11 for cooperating with the magnetic attraction part, and the air blowing assembly 2 is communicated with the air blowing module fixing plate 1 through the sealing part.

[0031] Based on the above structure, the blowing component 2 can be quickly fixed on the air blowing module fixing plate 1 through the magnetic attraction part, and at the same time, quick disassembly can also be achieved. The limiting part and the mating holes 11 provided on the air blowing module fixing plate 1 can quickly position the blowing component 2. On the one hand, it speeds up the assembly efficiency of the blowing component 2, on the other hand, it can make the magnetic attraction part more precisely assembled, and can also make the overall assembly structure more compact; through the sealing part, the sealing performance of the connection can be increased, and gas leakage can be avoided during quick assembly.

[0032] As an example, the limiting part can be a limiting strip groove 12. A plurality of limiting strip grooves 12 are arranged along the width direction of the air blowing module fixing plate 1. At least 2 mating holes 11 are arranged in each limiting strip groove 12, and the 2 mating holes 11 are symmetrically arranged along the central position of the limiting strip groove 12 where they are located.

[0033] Based on the above structure, by providing a plurality of limiting strip grooves 12, multiple blowing components 2 can be synchronously assembled on one air blowing module fixing plate 1. At the same time, by arranging a plurality of mating holes 11 in the limiting strip grooves 12, it can accommodate a plurality of magnetic attraction parts, providing an assembly basis for the stable magnetic attraction of the blowing component 2.

[0034] As an example, a cylindrical groove 13 for cooperating with the sealing part is also arranged in the limiting strip groove 12. A stepped hole 14 is arranged at the bottom of the cylindrical groove 13, and the stepped hole 14 is coaxially arranged with the cylindrical groove 13; an air inlet hole for connecting with the external air inlet joint 3 is arranged at the top of the cylindrical groove 13.

[0035] The sealing part can include a sealing joint 21, a sealing flat gasket 22 and an O-ring 23; a threaded head is arranged at the bottom of the sealing joint 21, the sealing flat gasket 22 and the O-ring 23 are assembled on the sealing joint 21, and the sealing joint 21 is connected to the blowing component 2 through the threaded head.

[0036] Based on the above structure, the sealing flat gasket 22 can prevent air leakage at the connection between the threaded head and the blowing component 2, ensuring the overall sealing performance. At the same time, when the O-ring 23 contacts the cylindrical groove 13, the O-ring 23 can perform axial sealing, further ensuring the overall airtightness. At the same time, the stepped hole 14 reserves a accommodation space for the sealing flat gasket 22 and can also perform sealing to a certain extent. Through this multi-sealing structure, the overall airtightness is ensured, enabling the blowing component 2 to not only be quickly disassembled and connected, but also ensuring the airtightness of the connection.

[0037] As an example, the end of the sealing joint 21 in contact with the air blowing module fixing plate 1 is a frustum-shaped structure, and a sealing limiting groove 24 for accommodating the O-ring 23 is arranged along the length direction of the sealing joint 21; 2 O-rings 23 can be arranged in the sealing limiting groove 24.

[0038] Based on the above structure, a frustum-shaped structure is provided at the front end of the sealing joint 21, which can play a guiding role and enable the sealing joint 21 to be more quickly snapped into the cylindrical groove 13. At the same time, multiple sealing rings are provided on the sealing joint 21 to enhance the sealing effect.

[0039] As an example, the magnetic attraction part can be a magnet 30. The shape of the magnet 30 is the same as the structure of the mating hole 11, and the magnet 30 is fixed on the end face of the air blowing assembly 2.

[0040] Based on the above structure, by arranging the magnet 30 on the end face of the air blowing assembly 2, the distance between the magnet 30 and the air blowing module fixing plate 1 can be reduced. Under the condition of the same size and material of the magnet 30, the magnetic attraction force can be increased as much as possible.

[0041] As an example, the air blowing assembly 2 as a whole can include a mating plate 25, a communication hole 26, a confluence square pipe 27, a plug 28 and an air blowing needle 29. The magnets 30 are arranged in multiple numbers in the length direction of the mating plate 25. The communication hole 26 is connected to the sealing joint 21. The confluence square pipe 27 is arranged through the mating plate 25 along the length direction. The plugs 28 are respectively arranged at both ends of the confluence square pipe 27. Multiple assembly holes are provided below the confluence square pipe 27, and the air blowing needles 29 are assembled in the assembly holes.

[0042] Internal threads can be provided in the assembly holes, and external threads can be provided on the air blowing needles 29. The air blowing needles 29 are fixedly connected with the assembly holes by thread fitting.

[0043] Based on the above structure, after the air blowing module fixing plate 1 and the air blowing assembly 2 are magnetically attracted and fixed, the air flow enters through the air inlet joint 3, then is transported through the confluence square pipe 27, and finally is output outward through the air blowing needles 29. In this solution, the O-ring 23 on the sealing joint 21 forms a radial seal with the cylindrical groove 13, and the end face forms an axial seal, ensuring that the assembly forms a seal while ensuring detachable, and ensuring the normal operation of air blowing.

[0044] As an example, the air blowing needle 29 can be a straight blowing needle or an inclined blowing needle. This solution can select the air blowing needle 29 according to the actual needs, making it more convenient to use and enabling quick disassembly and assembly.

[0045] As an example, six limiting strip grooves 12 can be provided on the air blowing module fixing plate 1.

[0046] As an example, hand-tightening screw mounting holes 4 can be provided at the same positions on the air blowing module fixing plate 1 and the air blowing assembly 2. When the device needs to be transported, the air blowing module fixing plate 1 and the air blowing assembly 2 are fixed by screws to ensure safety during transportation.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
