[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0027] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0028] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0029] See also Figure 1 、 Figure 2 and Figure 3 The present invention proposes an electromagnetic virus sample collection device (hereinafter referred to as the collection device), which includes a device body 100, a collection cavity 110 is formed on the device body 100, a metal pattern structure 200 is arranged in the collection cavity 10, and a conductive layer 300 is arranged between the metal pattern structure 200 and the device body 100. The metal pattern structure 200 is arranged on the conductive layer 300, and a circuit pin 120 is provided on the device body 100. One end of the circuit pin 120 is connected to the metal pattern structure 200, and the other end of the circuit pin 120 is used to electrically connect to an external power supply.

[0030] It is understandable that after the circuit pin 120 is connected to the power supply, the current flows through the metal engraved structure 200 and generates an electromagnetic effect on the metal engraved structure 200, thereby being able to adsorb the sample placed in the collection chamber 110. Of course, it is common knowledge that a wire with current flowing through it can generate a magnetic field around it, so we will not elaborate on this in detail.

[0031] During the collection operation, it is only necessary to place saliva in the collection chamber 110 and connect the circuit pin 120 to collect the virus in the saliva. After the collection device collects the virus sample, it is sent to the detection device (such as a spectral analysis detection device) to quickly complete the virus detection. Of course, how to detect the virus is not within the scope of improvement of this solution, so we will not elaborate on this in detail.

[0032] Using this collection device to collect virus samples can not only effectively avoid the situation where traditional cotton swab sampling easily causes human discomfort, but also effectively improve the speed and efficiency of sampling, thereby providing strong assistance to epidemic prevention work.

[0033] Based on the above solution, preferably, the device body 100 is provided in a cylindrical structure, and a conductive layer 300 is provided inside the cylinder, and a metal engraving structure 200 is provided on the conductive layer 300. The conductive layer 300 can be a metal film or a conductive film.

[0034] Preferably, the device body 100 is made of plastic material, but other materials may also be used. Using plastic material can effectively reduce production costs.

[0035] Preferably, the metal patterned structure 200 is made of gold, silver, or a gold-silver alloy, which can improve the conductivity of the metal patterned structure 200, thereby effectively enhancing the magnetic effect of the metal patterned structure 200 and effectively improving the adsorption of viruses.

[0036] See also Figure 1 and Figure 4 On the basis of the above scheme, the collection device also includes a sealing cover 130, which is provided on the device body 100. The sealing cover 130 is used to seal the collection chamber 110, thereby preventing other impurities from entering the collection chamber 110 and affecting the sampling accuracy of the collection device.

[0037] At the same time, the collection device also includes a handshake bracket 140, one end of the handshake bracket 140 is used to install the device body 100, and the other end of the handshake bracket 140 is for the sampling personnel to grasp.

[0038] It is understandable that when sampling, the sampling personnel holds the handshake bracket 140, further puts saliva into the collection chamber 110, and at the same time connects the circuit pin 120 to complete the virus collection action.

[0039] Specifically, a power socket 141 is provided at one end of the handshake bracket 140 . The power socket 141 is electrically connected to an external power source and is used to place the device body 100 .

[0040] See also Figure 4 On the basis of the above scheme, preferably, the collection device further includes a sample column 400, which is arranged in the collection chamber 110, and one end of the sample column 400 is fixedly set on the device body 100, and the other end of the sample column 400 is used to carry and place the collected sample (i.e., saliva or other samples).

[0041] Specifically, the sample column 400 is provided with a column head at one end for placing the collected sample, and both ends of the column head extend inward, thereby being able to better hold the collected sample.

[0042] As another preferred embodiment, the sample column 400 is movably arranged in the collection chamber 110, that is, one end of the sample column 400 passes through the device body 100 and extends out of the collection chamber 110. When sampling, the sample column 400 is moved out of the collection chamber 110, and after adding the saliva sample on it, the sample column 400 is moved back into the collection chamber 110. After the circuit pin 120 is energized by current, the metal engraved structure 200 generates an electromagnetic effect and adsorbs the virus from the saliva on the sample column 400 onto the metal engraved structure 200, thereby completing the collection of the sample. This design can effectively improve the convenience of the collection device and the efficiency of the sampling function.

[0043] See also Figure 4 and Figure 5 On the basis of the above solution, the metal engraving structure 200 is arranged in concentric ring sawtooth configuration, and it is an acute-angle sawtooth structure.

[0044] See also Figure 4 and Figure 6 Preferably, the metal carving structure 200 can also be arranged in a spiral sawtooth structure, and it is an acute-angle sawtooth structure.

[0045] See also Figure 4 and Figure 7 Preferably, the metal engraving structure 200 can also be arranged in the form of caltrop serrations, and it is a sharp-angled serration structure.

[0046] In the setting of the metal patterned structure 200, the sawtooth structure is set in a sharp-angled sawtooth at one end away from the conductive layer 300, which can enhance the adhesion effect of the electron circulation, effectively improve the magnetic effect generated by the metal patterned structure 200, and greatly improve the collection effect of the collection device.

[0047] Of course, the above-mentioned configuration of the metal carving structure 200 is a preferred method, and this solution does not limit other structures of the metal carving structure 200.

[0048] In the description of this specification, the reference terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" mean that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0049] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
