In some embodiments, the housing 10 includes a first shell 10a and a second shell 10b, and the second shell 10b is connected to the first shell 10a in a matching manner to form the accommodating space 100. The first case 10a or the second case 10b is provided with a first hole 101, and the display 13 is provided to the second case 10b or the first case 10 a. The housing 10 is formed by the first and

second shells

10a and 10b which are separated from each other and are oppositely combined and connected, so that the components arranged in the accommodating space 100 can be easily mounted on or dismounted from the housing 10.

Alternatively, the first shell 10a and the second shell 10b may be fixedly connected by one or more of a screw structure, an adhesive, a snap structure, or other connection structure to fix the relative position between the first shell 10a and the second shell 10b, and make the first shell 10a and the second shell 10b not easily separated, thereby ensuring the structural stability of the portable microscope 1.

Optionally, the first shell 10a and the second shell 10b may have substantially the same shape, that is, the first shell 10a and the second shell 10b may be both of a kidney-shaped shell shape with an opening enclosing a part of the accommodating space 100, and the openings of the first shell 10a and the second shell 10b are respectively buckled relatively. It is understood that the shape of the first shell 10a and the second shell 10b is not particularly limited as long as the first shell 10a and the second shell 10b can enclose the accommodating space 100 for accommodating various functional components of the portable microscope 1 when being connected in an involution manner.

In the present embodiment, the first hole 101 is opened in the first casing 10a, and the display 13 is disposed in the second casing 10b, that is, the first casing 10a may be formed as one side of the casing 10, the second casing 10b may be formed as the other side of the casing 10, and the first casing 10a and the second casing 10b have substantially the same shape.

Referring to fig. 4, in some embodiments, the second shell 10b is provided with a first clearance hole 102 communicating with the accommodating space 100, and the display 13 partially passes through the first clearance hole 102 to be electrically connected to the circuit board 11, so that the electrical connection routing distance between the display 13 and the circuit board 11 can be shortened, and the layout of the portable microscope 1 is more compact.

Alternatively, the display 13 may be fixedly connected to the second casing 10b by gluing, snapping, or the like, so as to fix the relative position between the display 13 and the second casing 10b and make the display 13 not easily separated from the second casing 10 b.

Alternatively, the display 13 may be embedded on the outer surface of the second housing 10b, or the display 13 may cover the outer surface of the second housing 10b to improve the screen ratio of the portable microscope 1.

In some embodiments, the first clearance hole 102 is a stepped hole, the first clearance hole 102 has a first stepped surface 102a therein, the display 13 may partially abut against the first stepped surface 102a, and a display surface of the display 13 is lower than or flush with an outer surface of the second housing 10 b. By making the display surface of the display 13 lower than the outer surface of the second housing 10b, the possibility that the display 13 is scratched when in use can be reduced by utilizing the height difference between the display surface of the display 13 and the outer surface of the second housing 10 b. And the surface of the portable microscope 1 can be made flat by making the display surface of the display screen 13 flush with the outer surface of the second housing 10 b.

Alternatively, the second clearance hole 103 may be opened on a surface of one side of the housing 10, a surface of the other side of the housing 10, or a circumferential surface of the housing 10. In other words, the second clearance hole 103 may be opened in the first case 10a, or the second clearance hole 103 may be opened in the second case 10b, or when the second clearance hole 103 is opened in the circumferential surface of the housing 10, the second clearance hole 103 may be formed by two grooves opened in the first case 10a and the second case 10b, respectively, being in opposite communication. It is understood that the opening position of the second clearance hole 103 may be set according to the placement position of the functional element 14, and the embodiment is not particularly limited as to the opening position of the second clearance hole 103.

In an alternative embodiment, the function 14 may be a key, so as to implement a control function of the portable microscope 1 by the user. At this time, one end of the function 14 may be higher than the surface of the housing 10, so that the user can press the function 14 from the outside of the portable microscope 1.

In a second example, the function 14 may be a control key of a shooting function of the portable microscope 1, so that the portable microscope 1 can be controlled by the function 14 to shoot or video-shoot the light signal collected by the camera assembly 15 at a desired timing.

In a third example, the function 14 may be an adjustment button, for example, because the display surface of the display 13 is small, the display 13 may only display a part of the imaged picture captured by the camera assembly 15, and in this case, the function 14 may be used to zoom in or out the picture displayed by the display 13 or adjust the position of the area displayed by the display 13.

In another alternative embodiment, the function component 14 may be a sound device, so that the functions of voice prompt, music playing and the like of the portable microscope 1 can be realized, so as to improve the use convenience and use experience of the user.

Alternatively, when the functional component 14 is a sound box, one functional component 14 may be disposed in the accommodating space 100 corresponding to the plurality of second clearance holes 103, that is, one functional component 14 may emit sound towards the plurality of second clearance holes 103, so as to improve the sound emission effect of the functional component 14.

In yet another alternative embodiment, the functional component 14 may be a microphone, so as to implement the sound collecting function of the portable microscope 1, so that the portable microscope 1 can cooperate with the circuit board 11 to implement the sound recording function.

In yet another alternative embodiment, the function part 14 may be a charging interface or a data transmission interface, so that the function of charging the portable microscope 1, or transmitting image or video data taken by the portable microscope 1 to other electronic devices, or receiving data information from other electronic devices may be realized.

In some embodiments, to facilitate the disposing of the magnifying glass 12, the first hole 101 may be a stepped hole, the first hole 101 has a second stepped surface 101b therein, the magnifying glass 12 partially abuts against the second stepped surface 101b, and an end surface of the object side 120 is lower than or flush with the outer surface of the first shell 10 a. By making the end surface of the object side end 120 lower than the outer surface of the first shell 10a, the height difference between the end surface of the object side end 120 and the outer surface of the first shell 10a can be utilized to reduce the possibility that the mirror surface of the magnifying lens 12 is scratched and damaged during use, which is beneficial to prolonging the service life of the portable microscope 1 and simultaneously does not affect the view finding of the magnifying lens 12. And by making the end face of the object side end 120 flush with the outer surface of the first housing 10a, the surface of the portable microscope 1 can be made flat.

Optionally, the magnifying lens 12 may be fixedly connected to the first shell 10a by gluing, snapping, or the like, so as to fix the relative position between the magnifying lens 12 and the first shell 10a, and make the magnifying lens 12 not easily detached from the first shell 10 a.

Alternatively, the magnifying lens 12 may comprise one or more pieces of lens, and when the magnifying lens 12 comprises a plurality of pieces of lens, it is possible to achieve an increase in magnification of the magnifying lens 12, thereby increasing the microscopic quality of the portable microscope 1.

In some embodiments, the accommodating space 100 is provided with a first limiting structure 104, the first limiting structure 104 is located at the periphery of the camera assembly 15, and the first limiting structure 104 is configured to limit the position of the camera assembly 15 in the accommodating space 100, so that the lens end of the camera assembly 15 faces the first opening 101a, thereby ensuring that the optical signal collected by the camera assembly 15 is always the optical signal passing through the image side end 121 of the magnifying lens 12, and the image displayed on the display 13 is the magnified image of the object aligned with the object side end 120 of the magnifying lens 12, so as to ensure the microscopic function of the portable microscope 1.

Alternatively, the first limiting structure 104 may be a plurality of protrusions spaced along the periphery of the camera head assembly 15, or the first limiting structure 104 may be a protrusion extending along the periphery of the camera head assembly 15. It should be understood that, as long as the first limiting structure 104 can limit the relative position of the camera head assembly 15 and the housing 10, the number and the arrangement of the first limiting structures 104 are not particularly limited in this embodiment.

For example, the first limiting structure 104 is a plurality of bumps, for example, two bumps, where the two bumps may be located on the same side of the camera assembly 15, and a space between the two bumps is an avoiding routing space for the electrical connection routing between the camera assembly 15 and the circuit board 11.

Alternatively, the first limiting structure 104 may be protruded from the inner surface of the second shell 10b, and the camera head assembly 15 may be fixedly connected to the inner surface of the second shell 10b by gluing, snapping, or the like, so that the camera head assembly 15 is not easily separated from the second shell 10 b.

Further, the lens end of the camera head assembly 15 may be provided with a transparent protection plate 150 to protect the end surface of the lens end of the camera head assembly 15 from being damaged.
