[0026] See also Figure 1 , Figure 2 and Figure 3 The present invention provides an air blowing type virus sample collection device (hereinafter referred to as the collection device), which includes a device body 100, on which an air blowing channel 110 is opened, the air blowing channel 110 runs through the device body 100, one end of the air blowing channel 110 is an air blowing port 111, and the other end of the air blowing channel 110 is an air outlet 112, and an air flow swirl structure 200 is arranged in the device body 100, the air flow swirl structure 200 is fixedly arranged in the device body 100, and the air flow swirl structure 200 is arranged in the air blowing channel 110.

[0027] Specifically, one end of the airflow swirl structure 200 is set in a conical structure 210, and the other end of the airflow swirl structure 200 is provided with a groove 220, and the groove 220 is opened in an arc-shaped structure. The end of the airflow swirl structure 200 with the conical structure 210 is set toward the blowing port 111, and at the same time, the end of the airflow swirl structure 200 with the groove 220 is set toward the air outlet 112, and a metal engraved structure 300 is set at the groove 220, and the metal engraved structure 300 is used to be connected to an external power supply.

[0028] It can be understood that when the collection device blows air from the blowing port 111, the airflow will flow through the blowing channel 110, and at the same time, a vortex impact action will be generated when passing through the airflow vortex structure 200. The airflow will be further enhanced at the groove 220. The arc-shaped structure of the groove 220 can effectively improve the strength of the vortex impact. At the same time, a metal groove structure 300 for connecting to an external power supply is provided at the groove 220. After power is turned on, an electromagnetic effect will be generated, thereby being able to adsorb the virus in the airflow on the metal groove structure 300.

[0029] Please continue reading Figure 3It can be understood that in the above process, the airflow will be divided into two airflows when passing through the conical structure 210. After the two airflows are accelerated by the airflow vortex structure 200 in the blowing channel 110, they are further converged and collided at the groove 220. After the two airflows converge and collide, vortices are generated. The vortices will blow the viruses in the airflow to the groove 220, and the viruses will gather and attach to the groove 220. After the metal engraved structure 300 is energized, an electromagnetic effect will be generated on its surface, and then the viruses in the airflow can be adsorbed on the metal engraved structure 300 to complete the virus collection. This not only avoids the problem that cotton swab sampling easily causes discomfort to the human body, but also speeds up the speed and efficiency of sample collection.

[0030] Specifically, the metal engraved structure 300 draws on the design of a thin lens transmitting a Gaussian beam with a half-width, similar to a semi-ellipse or semi-circle, and this position adopts one of the structures of inner surface caltrops, concentric serrated rings, or spiral serrated lines. Compared with the traditional grating grid ribs, the contact surface is much larger, thereby effectively enhancing the adsorption effect on viruses.

[0031] Specifically, a circuit pin 310 is provided on the device body 100, one end of the circuit pin 310 is electrically connected to the metal engraved structure 300, and the other end of the circuit pin 310 is used to be electrically connected to an external power supply. It can be understood that after the circuit pin 310 is connected to the external power supply, an electromagnetic effect will be generated on the metal engraved structure 300.

[0032] After the collection device has collected the virus sample, the collection device is sent to the detection device (such as a spectral analysis detection device) to quickly complete the detection of the virus. Of course, how to detect the virus does not fall within the scope of improvement of this solution, so no further elaboration will be made on this.

[0033] See also Figure 3 On the basis of the above solution, the metal engraving structure 300 is arranged close to the groove 220, and the metal engraving structure 300 is used to attach and carry the collected virus sample.

[0034] Specifically, the metal engraved structure 300 is arranged at the convergence point of the vortex generated by the airflow vortex structure 200. The electromagnetic effect generated by the metal engraved structure 300 after being energized strengthens the attachment of viruses in the airflow, thereby effectively improving the collection effect of the collection device 100. Of course, it is common knowledge that the metal engraved structure 300 generates electromagnetic effect after being energized, so no further elaboration is made on this.

[0035] Please continue reading Figure 3On the basis of the above scheme, the metal engraved structure 300 is opened in a horizontal strip structure, and the metal engraved structure 300 opened in a horizontal strip structure is arranged horizontally relative to the blowing channel 110. After the airflow in the blowing channel 110 is separated by the airflow vortex structure 200, it is strengthened at the arc of the airflow vortex structure 200, and at the same time, a counter-attack effect is generated at the groove 220. The vortex generated after further counter-attack will blow the virus to the groove 220 and the metal engraved structure 300, thereby effectively improving the collection effect of the virus.

[0036] See also Figure 3 One end of the airflow swirl structure 200 is provided with a conical structure 210, and the other end of the airflow swirl structure 200 is provided with a groove 220, and the groove 220 is provided with an arc-shaped structure. The transition structure between the conical structure 210 and the groove 220 is arranged in an arc shape, so that the airflow swirl structure 200 is like a heart-shaped structure. Of course, this scheme does not limit the angle of the conical structure 210 and the curvature of the groove 220, that is, it includes conical structures 210 of various angles and grooves 220 of various curvatures.

[0037] See also Figure 4 The present invention provides a preferred implementation manner. On the basis of the above solution, the metal engraving structure 300 is opened in a chamfered structure, and the sharp corner of the chamfered structure is arranged toward the groove 220.

[0038] It can be understood that when the airflow swirl structure 200 enhances the airflow, the airflow will flow along the chamfered structure, and then can generate vortex impact action on the chamfered structure again, thereby more effectively improving the virus collection effect and greatly improving the collection efficiency of the collection device.

[0039] See also Figure 5 On the basis of the above-mentioned embodiment, the metal engraving structure 300 can also be provided with a chamfered structure, that is, on the basis of the chamfered structure, the chamfered angle is made into an arc structure. Of course, this scheme does not limit the curvature of the arc structure, that is, any curvature is acceptable.

[0040] Based on the above solution, the metal engraving structure 300 is preferably made of gold, silver, gold-silver alloy or the like.

[0041] It should be explained that the above-mentioned metal pattern structure 300 is not a traditional planar grating or planar grid, but is made by adopting a non-traditional MO-CVD evaporation or magnetron sputtering process.

[0042] The metal pattern structure 300 preferably has an acute angle (when current flows through the conductor, the movement at the tip is the strongest), which can further effectively enhance the electromagnetic effect of the metal pattern structure 300 and thereby improve the adsorption effect of the metal pattern structure 300 on viruses.

[0043] Preferably, two electrical pins are led out from the device body 100, and both electrical pins are electrically connected to the metal pattern structure 300, which can greatly enhance the collection effect of viruses in conjunction with a special external circuit. Of course, different matching methods can be adopted according to different scenarios. This pattern mechanism 300 is a new type of anti-traditional concave-convex surface enhancement structure proposed for the first time, which has a higher collection effect for trace samples.

[0044] It is understandable that after the above current is passed through the metal engraved structure 300 made of metal, a magnetic field effect will be generated on the metal engraved structure 300, and the magnetic field can enhance the adsorption of viruses. Of course, the magnetic field effect generated by the metal engraved structure 300 when powered on belongs to the traditional prior art and will not be elaborated on in detail.

[0045] On the basis of the above scheme, the device body 100 includes a stereotyped plate 120 and an observation plate 130. The blowing channel 110 is opened on the stereotyped plate 120. At the same time, the air flow swirl structure 200 is fixedly arranged in the blowing channel 110. The observation plate 130 is covered on the stereotyped plate 120. The observation plate 130 is made of transparent material, which can be transparent glass, and of course, transparent plastic can also be used.

[0046] At the same time, an anti-skid thread 121 is provided on the outer side of the engraved plate 120. The provision of the anti-skid thread 121 can improve the gripping effect of the collection device.

[0047] On the basis of the above scheme, a fixing plate 400 is arranged on the device body 100, and the fixing plate 400 is arranged at one end of the air outlet 112 on the device body 100. At the same time, a filter membrane 410 is arranged between the fixing plate 400 and the device body 100. The filter membrane 410 is made of polytetrafluoroethylene, and is formed into a microporous film after expansion and stretching. The film is laminated on various fabrics and substrates with a special process to become a new type of filter material. The membrane has a small pore size (0.05-0.45μm), which can prevent the virus from spreading outward while maintaining air circulation.

[0048] Of course, PTFE membrane can also be used for filtering. The filter membrane 410 is used to prevent the spread of viruses in the airflow, so the filter membrane 410 can also be replaced by other virus filtering devices.

[0049] See also Figure 1 On the basis of the above solution, a blowing funnel 500 is provided on the device body 100 , and the blowing funnel 500 is provided on the blowing port 111 of the device body 100 . The blowing funnel 500 is preferably made of rubber.

[0050] It can be understood that the blowing funnel 500 is used to contact the mouth of the person being collected, and the anti-slip thread 121 on the stereotyped plate 120 can enhance the grip of the collection device, thereby improving the airtightness of the contact between the blowing funnel 500 and the mouth of the person being collected.

[0051] It can be understood that the air flow enters from the blowing port 111, is enhanced on the air flow swirl structure 200 and then flows out from the air outlet 112. At the same time, the filter membrane 410 filters the viruses in the air flow to prevent the viruses from expanding outward. The vortex impact generated on the air flow swirl structure 200 can blow the viruses in the air flow toward the groove 220, and the viruses are attached to the groove 220 to complete the collection of virus samples. The collection device can avoid the situation where cotton swab collection easily causes discomfort to the human body, and can also effectively improve the speed and efficiency of sample collection.
