Description

Technical Field

[0001] This invention relates to the field of optical instrument technology, and specifically to a vacuum suction cup microscope. Background Technology

[0002] Microscopic observation technology is widely used in many fields such as materials testing, biological sampling, industrial quality inspection, education and popular science, cultural relic inspection, and daily microscopic detail observation. It is a core means for microscopic morphology observation, sample defect screening, and detailed structural analysis. Compared with traditional large tabletop microscopes, portable microscopes have the advantages of small size, easy portability, and flexible application scenarios, enabling real-time observation in various scenarios such as outdoor sites, workpiece surfaces, irregular samples, and on-site materials.

[0003] Currently, several portable microscopes are available on the market, meeting users' basic microscopic observation needs and to some extent compensating for the shortcomings of traditional large microscopes, such as poor portability and limited application scenarios. However, existing portable microscopes still have many technical defects in practical use. Most mainstream portable microscopes are purely handheld designs. For example, CN216595718U discloses a portable handheld microscope that achieves on-site portable inspection through a lightweight structure. However, such devices require operators to continuously hold the device to focus and observe, which can easily lead to image shift and blurring due to hand tremors. Furthermore, the surface of the workpiece often has dust, debris, and other impurities adhering to it, requiring manual cleaning before use; otherwise, it can easily obstruct the observation area, affecting inspection efficiency and observation quality. To improve the stability of microscope observation, existing technologies have proposed various auxiliary fixation schemes. For example, CN219831504U discloses a variable-diameter adsorption microscope holder with magnetic pole rotation, which fixes the microscope to the surface of a metal workpiece through a magnetic attachment component, improving observation stability. However, this type of solution is only applicable to magnetic workpieces and cannot effectively fix non-magnetic workpieces such as glass, plastic, ceramics, and composite materials, thus limiting its applicability.

[0004] Therefore, this invention proposes a vacuum suction cup microscope to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a vacuum suction cup microscope for achieving handheld, stable, and fixed microscopic observation, thereby improving the accuracy of microscopic observation and its adaptability to various scenarios.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A vacuum suction cup microscope includes a battery pack, a pump pack, a spiral adjustment mechanism, and a suction cup distributed from top to bottom; the battery pack and the pump pack are detachably connected; the spiral adjustment mechanism is bonded to the bottom of the pump pack, and a camera located inside the spiral adjustment mechanism is fixedly connected to the bottom of the pump pack, with a microscope tube fixedly connected to the bottom of the camera; the bottom of the spiral adjustment mechanism is fixedly connected to the suction cup, and an observation hole aligned with the bottom of the microscope tube is opened at the center of the suction cup; the pump pack is connected to an adsorption component extending to the bottom of the suction cup, the adsorption component being used to provide negative or positive pressure to the lower surface of the suction cup; a switch for controlling the start and stop of the pump pack is fixedly connected to the surface of the pump pack; the pump pack is electrically connected to the battery pack.

[0007] Furthermore, the battery pack and the pump pack are connected by threads.

[0008] Furthermore, a rubber gasket is installed between the battery pack and the pump pack.

[0009] Furthermore, the lens barrel has an inverted triangular structure.

[0010] Furthermore, the bottom of the suction cup has a ring array of several fixing holes; the suction cup is connected to the screw of the spiral adjuster through the fixing holes.

[0011] Furthermore, the adsorption assembly includes several adsorption channels that are connected to the pump group; the bottom of the suction cup has several through holes that correspond one-to-one with the adsorption channels, and all the through holes are connected to the adsorption channels.

[0012] Furthermore, an LED strip is embedded in the inner wall of the spiral adjuster near the top of the suction cup, and the LED strip is electrically connected to the battery pack.

[0013] Furthermore, the diameter of the bottom end of the suction cup is 90.0–96.0 mm, the height of the suction cup is 18.0–19.0 ​​mm, the distance between the top of the observation hole and the top of the suction cup is 2.0–3.0 mm, and the outer diameter of the observation hole is 12.0–13.0 mm.

[0014] Furthermore, a telescopic rod is pivotally connected to the surface of the pump unit.

[0015] Furthermore, the usage steps are as follows: Step 1: Use the pump set to output gas into the adsorption channel to form a purging mode; purge and clean the area to be tested. Step 2: Place the suction cup on the area to be tested and evacuate the target area; once the silicone suction cup is fully adsorbed, proceed with the test. Step 3: Use the purging function again to restore the area to be tested to atmospheric conditions, then remove the device.

[0016] The above-mentioned solution offers the following advantages: This solution utilizes the pump unit, adsorption channel, and suction cup through-holes to form a negative pressure adsorption structure, ensuring the entire unit is firmly and securely attached to the sample surface. This eliminates the need for continuous manual handling, expanding the application scenarios of portable microscopes. Simultaneously, it effectively prevents focus shift and image blurring caused by hand tremors, enhancing the stability and accuracy of microscopic observation. Furthermore, it combines positive pressure purging and negative pressure adsorption functions. Before detection, airflow can remove dust and impurities from the test area, preventing interference with the observation field. After detection, the negative pressure can be quickly released, facilitating easy disassembly and assembly, effectively improving the standardization and efficiency of the detection process. It also provides a clean and stable observation environment for outdoor microscopic observation.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following detailed description illustrates the specific implementation method: Example 1:

[0024] like Figure 1 As shown, a vacuum suction cup microscope includes, from top to bottom, a battery pack 1, a pump pack 2 (with positive pressure air supply and negative pressure air suction functions, such as an F22N-12V miniature positive and negative pressure diaphragm air pump), a screw regulator 3, and a suction cup 4. Specifically, as... Figure 2 As shown, the battery pack 1 and pump pack 2 are connected by threads, and a rubber gasket 101 is provided between the battery pack 1 and pump pack 2 for sealing. The screw adjuster 3 is adhered to the bottom end of pump pack 2, and simultaneously... Figure 3 As shown, a camera 6, preferably a CCD camera, is screwed to the center of the bottom of the pump unit 2 and located inside the screw regulator 3. Furthermore, a lens barrel 7 with image magnification function is integrally formed at the bottom of the camera 6; the lens barrel 7 has an inverted triangular structure. The suction cup 4 is preferably made of silicone. Figure 4As shown, the suction cup 4 has several fixing holes 401 arranged in a ring at its bottom end; the suction cup 4 is connected to the screw of the screw adjuster 3 through the fixing holes 401. Simultaneously, an observation hole aligned with the bottom end of the lens barrel 7 is opened at the center of the suction cup 4. The pump assembly 2 is connected to several adsorption channels 201, and the bottom end of the suction cup 4 has several through holes 403 corresponding to the adsorption channels 201, all of which are connected to the adsorption channels 201. A switch 5 for controlling the start and stop of the pump assembly 2 is integrally formed on its surface (e.g., a long press of switch 5 starts positive pressure air supply; a short press of switch 5 starts negative pressure air intake. Alternatively, switch 5 can be a rotary structure, controlling the switching between positive and negative pressure by rotating clockwise / counterclockwise). The positive pressure purging mode and negative pressure adsorption mode are achieved by the forward and reverse rotation of the pump assembly 2; forward rotation results in negative pressure adsorption, and reverse rotation results in positive pressure purging.

[0025] In addition, an LED strip 8 is embedded in the inner wall of the screw regulator 3 near the top of the suction cup 4 to provide supplementary lighting and adapt to different lighting environments and observation needs. Both the LED strip 8 and the pump assembly 2 are electrically connected to the battery pack 1.

[0026] The specific implementation process is as follows: First, press and hold the control switch 5 on the outside of the pump group 2 to start the positive pressure air supply mode of the pump group 2. The airflow passes through multiple adsorption channels 201 and is ejected from the through hole 403 at the bottom of the suction cup 4, forming a purging airflow. This airflow is used to clean the observation points of the workpiece to be tested, removing surface dust, debris, and small impurities to prevent foreign objects from obstructing the observation area. After cleaning, the positive pressure mode is turned off. Then, the silicone suction cup 4 is placed stably on the cleaned surface to be tested. Press the switch 5 briefly to switch to the negative pressure vacuum mode. The pump group 2 continuously extracts air from the adsorption channels 201 and the inner cavity of the suction cup 4, creating a stable negative pressure inside the suction cup 4. The atmospheric pressure then firmly presses the silicone suction cup 4 against the sample surface, completely fixing the entire machine in place without the need for manual support. Once the suction cup 4 is fully engaged and the machine body is stable, the operator rotates the screw adjuster 3 to raise and lower the internal CCD camera 6 and the inverted triangular lens barrel 7 to fine-tune the focus. With the inner wall light strip 8 activated for supplementary lighting, and after adjusting to a clear image, microscopic morphology imaging and defect observation can be completed. After observation, switch 5 is activated again to turn on the positive pressure output of pump unit 2, allowing airflow into the suction cup 4 to balance the internal and external air pressure, releasing the negative pressure adsorption state, and easily and smoothly removing the entire machine from the surface to be tested, completing the entire inspection process.

[0027] Example 2:

[0028] The difference from Example 1 is that, as Figure 6As shown, a telescopic rod 9 is pivotally connected to the surface of pump unit 2. The telescopic rod 9 can preferably be based on the structure of a selfie stick on the market, thereby increasing the overall range of motion of the device and making this solution more suitable for field operations. Specifically, when observing large-sized samples, as described in Example 1, the device can be adsorbed onto the sample surface; while in some areas far from the observer in the field environment (areas that are difficult for human limbs to reach, such as rock crevices), the overall length can be adjusted by using the telescopic rod 9, and the microscope can be placed / retrieved by holding the telescopic rod 9. At the same time, since the sample surface is prone to moisture in the field environment, the blowing function described in Example 1 can also be used to clean water marks on the sample surface, facilitating the overall adsorption and installation of the microscope.

[0029] In addition, battery pack 1 is electrically connected to a Bluetooth module, which enables wireless connection with terminals (such as mobile phones) to facilitate staff to quickly understand the situation of the area to be tested, especially in complex outdoor environments where data cables are not convenient to distribute in some small areas (such as areas with many vegetation supports).

[0030] Example 3:

[0031] The difference from Embodiment 2 is that the bottom diameter of the suction cup 4 is 90.0 mm, the height of the suction cup 4 is 18.0 mm, the distance between the top of the observation hole 402 and the top of the suction cup 4 is 2.0 mm, and the outer diameter of the observation hole 402 is 12.0 mm.

[0032] Example 4:

[0033] The difference from Embodiment 3 is that the bottom diameter of the suction cup 4 is 93.0 mm, the height of the suction cup 4 is 18.5 mm, the distance between the top of the observation hole 402 and the top of the suction cup 4 is 2.5 mm, and the outer diameter of the observation hole 402 is 12.5 mm.

[0034] Example 5:

[0035] The difference from Example 4 is that the bottom diameter of the suction cup 4 is 93.0 mm, the height of the suction cup 4 is 19.0 mm, the distance between the top of the observation hole 402 and the top of the suction cup 4 is 3.0 mm, and the outer diameter of the observation hole 402 is 13.0 mm.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
