Description

Chamber model with laser projection

This creation is about a chamber model with a laser projection, in particular a projection of the teaching image onto a stereoscopic ear canal model, so that the learner can easily observe and observe through the projection on the ear canal model. Learn about the various conditions of the ear.

Press, the projector has been launched for many years, because it only needs to be a projection device, can be used to display dynamic images, or display the display content of the computer, for example, in a large conference, the conference content will be stored in the notebook. Through the projector, the enlarged display is displayed for many people, or during teaching, the teaching slides stored in the notebook computer are displayed through the projector for teaching.

However, the projection of the existing ear teaching is to project the teaching image onto the plane screen, and use the plane image to enable the learner to observe and learn various diseases of the ear. However, whether it is the ear canal or the inner ear canal of the human body, it is a three-dimensional shape, not a flat surface. The use of a flat-type teaching projection is not easy for the learner to understand the actual three-dimensional condition of the various diseases of the ear, and the teaching effect is greatly reduced.

In view of this, the creator of this case has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author of this case has finally achieved a practical and practical creation.

The main purpose of this creation is to provide a chamber model with laser projection, which is to project the teaching image onto the stereoscopic ear canal model, so that the learner can easily observe and observe through the projection on the ear canal model. Learn the actual three-dimensional condition of the various conditions of the ear.

In order to achieve the above objective, the present invention has a laser projection chamber model, which mainly includes: a first cavity and a second cavity; wherein a first rear end of the first cavity is provided with a a laser projector comprising a microelectromechanical scanning mirror capable of projecting a scanning beam, a first front end adjacent to the opening of the first cavity is provided with a dimming element, and a front end of the dimming element is provided with a reduction a lens, the front end of the reducing lens is provided with a mirror; and the second cavity is disposed at a corresponding position of the first cavity, and has a passage to form an ear canal, and the second front end of the second cavity Having a viewing port, the second rear end is provided with an imaging surface, so that the scanning beam reflected by the mirror can be projected onto the imaging surface through the opening below the second rear end of the second cavity; Thereby, when used, the learner can observe the stereoscopic projection of various ear diseases on the imaging surface from the viewing port, so that the reflected light diffusion imaging method is adopted, so that the laser beam does not directly illuminate the learner's eyes, and the pair can be avoided. Eye damage, At the same time, the learner can easily observe and learn the actual three-dimensional appearance and condition of various diseases of the ear through the projection on the ear canal model, thereby achieving the effect of greatly improving the learning effect.

The first picture is a schematic plan view of a chamber model with laser projection.

This creation is related to a "chamber model with laser projection". Please refer to FIG. 1 , the chamber model with laser projection of the present invention mainly includes: a first cavity 11 and a The second cavity 21.

The first rear end of the chamber 111 of the first cavity 11 is provided with a laser projector 10, and the laser projector 10 includes a microelectromechanical scanning mirror (not shown) capable of projecting a scanning beam of various ear conditions, a first front end of the chamber 111 of the first cavity 11 has an opening 12 through which the scanning beam of the laser projector 10 can be projected. A cavity 111 of a cavity 11 is provided with a set of light-transmitting mirrors (13, 14) adjacent to the front end of the opening 12. In the present creation, the light-transmitting mirrors (13, 14) are respectively a light-reducing element 13 and a Reduced lens The dimming element 13 is disposed adjacent to the front end of the opening 12. The front end of the dimming element 13 is provided with a reducing lens 14. The front end of the reducing lens 14 is provided with a reflecting mirror 15 at a reflection angle for projecting. The scanning beam can be first dimmed by the dimming element 13 and reduced by the reducing lens 14, and then reflected by the mirror 15 and projected.

The second cavity 21 is disposed at a position corresponding to the first cavity 11, and the passage in the chamber 213 of the second cavity 21 forms an ear canal, and one of the chambers 213 of the second cavity 21 The second front end is provided with a viewing port 211, and the second rear end is provided with an imaging surface 22, so that the scanning beam reflected by the mirror 15 can be further passed under the second rear end of the chamber 213 of the second cavity 21. The port 212 is projected onto the imaging surface 22.

Referring to the composition of the above components, please refer to FIG. 1 again. When using, the learner can observe the stereoscopic projection of various ear diseases on the imaging surface 22 from the viewing port 211. Thus, using the reflected light diffusion imaging method to make the laser The light beam does not directly illuminate the learner's eyes, and can avoid damage to the eyes. At the same time, the learner can easily observe and learn the actual three-dimensional appearance and condition of various diseases of the ear through the projection on the ear canal model 20. To achieve the purpose and effectiveness of greatly improving the learning effect.

Referring to FIG. 1 again, the reflection angle of the mirror 15 can be 30 degrees backward.

Referring again to FIG. 1, there is no space between the first cavity 11 and the second cavity 21.

Referring to FIG. 1 again, the dimming element 13 can be a black lens.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives, and in accordance with the provisions of the Patent Law, a patent application is filed. However, the above is only the preferred embodiment of the present invention, and the scope of the creation of the present invention cannot be limited by this; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the content of the creation specification are All should remain within the scope of this creation patent.
