Image acquisition unit 2 and image observation unit 3 are both located inside main body 9. The rear main body shell 71 is provided with a first opening 711 for exposing image acquisition unit 2, and the front main body shell 61 is provided with a second opening 611 for exposing image observation unit 3; power unit 5 is connected to image acquisition unit 2, image observation unit 3, and main control unit 4; transparent protective cover 8 is provided on the rear main body shell 71 and surrounds image acquisition unit 2.

[0037] In practical use, the user holds the handle 10 and places the transparent protective cover 8 over the outside of the object to be observed. At this time, the image observation unit 3 acquires an image of the object, and then the main control unit 4 processes the image (e.g., image magnification). The user can then observe the object in real time through the image observation unit 3. This invention, by setting a transparent protective cover 8 on the rear main body shell 71, avoids interference caused by external airflow fluctuations during use. It also provides dust and water protection during outdoor use. Furthermore, the protective cover is made of transparent material, allowing external light to enter the observation area, preventing poor lighting and dim surroundings when the object is inside the cover, thus reducing visual impact. The buttons on the front and sides are all positioned at the same height, resulting in a compact structure that is easy for children to operate with one hand.

[0038] This invention also includes the basic functions of a magnifying glass, namely: a convex lens 11, and both the front handle housing 62 and the rear handle housing 72 are provided with a third opening 12, with the convex lens 11 disposed within the third opening 12. Users can also observe the object using a conventional convex lens 11.

[0039] To ensure the convex lens 11 is securely mounted on the end of the handle 10, this invention further includes a front fixing member 13 and a rear fixing member 14. Both the front fixing member 13 and the rear fixing member 14 are provided with several buckles 15, and both the front handle housing 62 and the rear handle housing 72 are provided with slots 16 that match the buckles 15. The buckles 15 and slots 16 engage with each other to fix the convex lens 11 within the third opening 12. The front fixing member 13 and the rear fixing member 14 can also be used as decorative parts; different color schemes can be used to meet the needs of different consumers and improve the visual effect.

[0040] Furthermore, the image acquisition unit 2 includes: a first support plate 21 and an electronic lens 22 connected to the main control unit 4; the first support plate 21 is fixed inside the main body 9, and the electronic lens 22 is fixed on the first support plate 21 and corresponds to the position of the first opening 711.

[0041] If an electronic magnifying glass is used in a dim environment, the object to be observed may not be clearly observed due to the dim light. Therefore, the image acquisition unit 2 also includes a number of LED beads 23 connected to the main control unit 4. The LED beads 23 are set on the first support plate 21 and surround the electronic lens 22. Correspondingly, the rear main body housing 71 has a fifth opening 22 at the position corresponding to the LED beads 23, which is the same number as the number of LED beads 23, so that the light can directly shine on the object to be observed.

[0042] Furthermore, a PVC lampshade film 17 is provided to cover the circular area surrounding the rear main body shell 71 of the transparent protective cover 8. That is, the PVC lampshade film 17 covers the area of ​​the lamp beads 23. The PVC lampshade film 17 can effectively protect the built-in lamp beads 23, reduce the damage of the external environment to the light source, and extend the service life of the lamp beads 23. The lampshade film is provided with a fourth opening 171 for the image observation unit 3 to be exposed.

[0043] Furthermore, the image observation unit 3 includes a screen support frame 31 and a screen 32; the screen 32 is fixed inside the main body 9 by the screen support frame 31, and the position of the screen 32 corresponds to that of the second opening 611. The surface of the screen 32 is also covered with an acrylic protective cover 18 to prevent the screen 32 from being scratched.

[0044] The power supply unit 5 includes a charging interface 51 and a lithium battery 52. ​​The charging interface 51 is connected to the image acquisition unit 2, the image observation unit 3, and the main control unit 4, and is located on the main body 9. The lithium battery 52 is connected to the image acquisition unit 2, the image observation unit 3, and the main control unit 4, and is located on the handle 10. Specifically, the charging interface 51 is fixed on the first support plate 21 and is located at the edge of the main body 9. The first support plate 21 is provided with a lithium battery connection terminal 19, and the lithium battery 52 is connected to the image acquisition unit 2 through the lithium battery connection terminal 19.

[0045] The main control unit 4 is mounted on the PCBA assembly 20, and the PCBA assembly 20 is also equipped with an SD memory card 20 connected to the main control unit 4 to store image information.

[0046] The connection between the front main body housing 61 and the front handle housing 62 is set to be arc-shaped, the connection between the rear main body housing 71 and the rear handle housing 72 is set to be arc-shaped, and the shape of the main body 9 is set to be round. Based on this setting, the overall appearance of the electronic magnifying glass is more beautiful and less prone to scratches.

[0047] The following explanation will be based on actual use:

[0048] The user presses and holds the start button 101 to turn on the electronic magnifier. The user can switch between settings and observation by pressing the menu button 103. In the settings menu, the user can use the "+" button 105 and the "-" button 106 to select up and down. The user can confirm by pressing the photo button 102.

[0049] The user holds the handle 10 and covers the outside of the object to be observed with the transparent protective cover 8. At this time, the image of the object to be observed is acquired through the image observation unit 3. Subsequently, after the image is processed by the main control unit 4, the user can observe the object to be observed in real time in the image observation unit 3.

[0050] During this period, you can switch between taking pictures and observing using the photo button 102, and zoom in or out of the observation interface using the "+" button 105 and the "-" button 106. If there is insufficient light, you can turn on the LED bead 23 using the brightness button 104 for supplemental lighting. Each time you press the brightness button 104, the power of the LED bead 23 increases by one level. After continuously pressing the brightness button 104, the light gradually increases to the maximum. Press the brightness button 104 again to turn off the LED bead 23.

[0051] After observation, you can play or pause the image information in the album by briefly pressing the shutter button 102, and switch between previous and next image information by using the "+" button 105 and the "-" button 106.

[0052] It should be noted that the main control unit 4 processes the image information and controls the screen 32 to display the image information. For related information, please refer to the prior art.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
