The application provides a mouth mirror and a preparation method thereof, which aim to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
The embodiment of the application provides a mouth mirror 1, include: a lens 11 and a holder 13.
The lens 11 includes: a first substrate 110 and at least two first hydrophobic structures 111.
The backlight side of the first substrate 110 is fixedly connected to the bracket 13.
At least the first hydrophobic structures 111 are arranged in an array and are all connected with the light-facing side of the first substrate 110.
A size of a portion of the at least one first hydrophobic structure 111 close to the first substrate 110 is smaller than a size of a portion of the first hydrophobic structure 111 far from the first substrate 110.
The inventor of the application researches and discovers that in order to enable the mouth mirror 1 to have the defogging and dewatering effects, the lens 11 of the mouth mirror 1 can be treated, and the lens 11 can be in contact with water but can not leave water stains. The suspension structure can suspend liquid in the air, so that the contact angle between the liquid and the suspension structure is increased, and the hydrophobic effect is achieved.
In this embodiment, the first hydrophobic structure 111 on the lens 11 enables the lens 11 of the mouth mirror 1 to achieve the antifogging and hydrophobic effects, the cost is low, the whole structure of the mouth mirror 1 is simple, the use is easy, a temperature control device with large occupied space is not needed, and the macro structure is as shown in fig. 1.
Optionally, the mouth mirror 1 provided by the embodiment can be used for one time, so that a disinfection procedure is omitted, and the problem of bacterial infection caused by difficulty in complete disinfection of the mouth mirror 1 is avoided. And the degree of the defogging effect can be adjusted by changing the density of the first hydrophobic structures 111.
Optionally, the bracket 13 may be made of a plastic material, so that the mouth mirror 1 is disposable, and cost is saved.
The inventors of the present application consider that when a liquid is in contact with the surface of an object, a contact angle is generated, and when the contact angle is less than 90 °, we consider it hydrophilic; less than 5 ° we consider superhydrophilic; when the contact angle is greater than 90 °, we consider the surface hydrophobic; especially when the surface contact angle is greater than 150 °, it is called superhydrophobic. To obtain the defogging effect, the super first hydrophobic structure 111 needs to be designed. The suspended microstructure can ensure that liquid is suspended, so that the contact angle between the liquid and the microstructure is increased, and the hydrophobic effect is obtained. Therefore, the application provides the following possible implementation manner for the lens 11 of the mouth mirror 1:
as shown in fig. 3, the first hydrophobic structure 111 of the lens 11 of the embodiment of the present application includes: a first cylinder 112 and a first cover 113.
One end of the first pillar 112 is connected to the light-facing side of the first base 110, and the other end is connected to the first cover 113.
The radial dimension of the first cap 113 is at least greater than the radial dimension of the other end of the first cylinder 112.
In this embodiment, the first hydrophobic structure 111 on the light-facing side of the lens 11 includes a first cylinder 112 and a first cover 113, a radial dimension of the first cover 113 may be larger than a radial dimension of the first cylinder 112, the first cylinder 112 is located between the first substrate 110 of the lens 11 and the first cover 113 of the first hydrophobic structure 111, and the first cover 113 is an overhanging structure with respect to the first substrate 110, and may have a hydrophobic effect. Namely, the mouth mirror 1 achieves the effect of defogging and dewatering in use by using the lens 11 with the dewatering effect. The present application provides several implementations of the first hydrophobic structure 111:
in one embodiment, the first cover 113 includes: a first top portion 1131 and a first extension 1132.
The first top 1131 is connected to the other end of the first cylinder 112, and the radial dimension of the first top 1131 is at least larger than the radial dimension of the other end of the first cylinder 112.
The first extension 1132 is connected to an edge of the first top 1131, and the first extension 1132 extends toward the first substrate 110.
In the present embodiment, in order to develop a hydrophobic surface with high contact angle, low adhesion, and low flow resistance suitable for various liquids, the first cover 113 of the first hydrophobic structure 111 is made to include a first top 1131 and a first extension 1132. Through the design of the first extension 1132, the first cover 113 is covered on the first cylinder 112 like a cap, and the first hydrophobic structure 111 is more delicate, so that the low surface energy liquid (i.e. the liquid that is difficult to adhere) can be effectively suspended without contacting the first substrate 110, and the lens 11 itself achieves the effect of defogging and hydrophobicity, as shown in fig. 2.
Optionally, the ratio between the size of the first cover 113 of at least one first hydrophobic structure 111 and the distance between two adjacent first hydrophobic structures 111 is not less than 1:2 and not more than 3: 5.
The inventor of the present application has found that, in order to achieve a better hydrophobic effect, the ratio of the size of the first cover 113 of the first hydrophobic structure 111 to the distance between two adjacent first hydrophobic structures 111 is 3: 5.
Optionally, the ratio of the size of the first cover 113 of the first hydrophobic structure 111 to the distance between two adjacent first hydrophobic structures 111 is 1:2, which may also play a role in hydrophobic.
In the second implementation method, the radial dimension of the end of the first hydrophobic structure 111 close to the light-facing side is smaller than the radial dimension of the end far away from the light-facing side.
In the present embodiment, by providing different radial sizes of the two ends of the first hydrophobic structure 111, a plurality of kinds of overhanging structures capable of hydrophobic property, such as an inverted trapezoid, a lower semicircle, etc., are provided, please refer to fig. 3, but the present invention is not limited to the shapes provided in the figure, and irregular shapes according to the present embodiment are also included.
In the third embodiment, the radial dimension of the end of the first hydrophobic structure 111 close to the light-facing side and the radial dimension of the end far from the light-facing side are both smaller than the radial dimension of the middle portion of the first hydrophobic structure 111.
While the foregoing analysis has mentioned that the overhang structure can achieve a good hydrophobic effect, this embodiment provides a structure that can also increase the contact angle of the liquid with the surface to achieve a hydrophobic effect. Referring to fig. 4, such a structure with two small ends and a large middle can also suspend liquid, thereby achieving the hydrophobic effect.
Based on the same inventive concept, the present application provides another stomatoscope 1, comprising: a lens 11, a hydrophobic membrane 12 and a support 13.
The hydrophobic membrane 12 includes: a second substrate 120 and at least two second hydrophobic structures 121.
At least two second hydrophobic structures 121 are arranged in an array, and are connected to one side of the second substrate 120.
The dimension of the portion of the at least one second hydrophobic structure 121 close to the second substrate 120 is smaller than the dimension of the portion of the overhanging structure away from the first substrate 110.
The other side of the second substrate 120 is connected to the light-facing side of the lens 11.
The backlight side of the lens 11 is fixedly connected to the holder 13.
In order to disinfect the mouth mirror 1 easily, and make convenient lens 11 and support 13 reuse of disinfecting, this embodiment provides a hydrophobic membrane 12, and hydrophobic membrane 12 itself can play the hydrophobic effect of defogging, again with hydrophobic membrane 12 and the laminating of ordinary lens 11, and hydrophobic membrane 12 uses transparent material to make, then can make ordinary lens 11 defogging hydrophobic and can see the inside mirror image in oral cavity clearly under the cooperation of transparent hydrophobic membrane 12.
In this embodiment, please refer to fig. 5 for the macro structure of the mouth mirror 1, the light-facing side of the lens 11 itself is attached with the hydrophobic film 12, so that the mouth mirror 1 can have the antifogging and hydrophobic effects while being used, and has the advantages of low cost, simple structure and easy use. Because the hydrophobic membrane 12 is attached to the lens 11, the hydrophobic membrane 12 is taken down after the mouth mirror 1 is used, and the rest structure of the mouth mirror 1 is disinfected, so that the disinfection process is simplified. And the degree of defogging can be adjusted by the density of the array of the second hydrophobic structures 121.
Optionally, the other side of the second substrate 120 is connected to the light-facing side of the lens 11, the hydrophobic film 12 and the lens 11 may be bonded in an oxygen ion bonding manner, after use, the stomatoscope 1 is placed into an oxygen plasma machine to be released from bonding, the hydrophobic film 12 is used for one time, and the bonding-released stomatoscope 1 can be directly sterilized by alcohol or by high temperature.
Alternatively, the hydrophobic film 12 may be made of glass or a flexible transparent film.
In one possible embodiment, the material of the hydrophobic membrane 12 is glass, and the size of the hydrophobic membrane 12 is comparable to the size of existing stomatoscope lenses. The material of the stomatoscope handle can be stainless steel. Hydrophobic membrane 12 may be a disposable material and the rest of the stomatoscope may be recycled. When the hydrophobic membrane 12 is needed to be used, the hydrophobic membrane 12 and the mouth mirror without the hydrophobic membrane 12 are placed into an oxygen plasma machine, and then the hydrophobic membrane 12 and the mouth mirror lens are pressed and bonded to obtain the mouth mirror with the hydrophobic membrane 12. When the lens is used, the hydrophobic membrane and the lens are only needed to be bonded, wherein the bonding can be achieved through heating, blowing and the like. The hydrophobic membrane 12 can be directly discarded as a disposable material, and then the stomatoscope body is sterilized, so that the operation is convenient, the cost is low, and the defogging effect of the stomatoscope can be realized without complicated structural improvement.
Optionally, the support 13 of the stomatoscope 1 is made of stainless steel material to improve the reuse rate.

The second top 1231 is connected to the other end of the second cylinder 122, and the radial dimension of the second top 1231 is at least greater than the radial dimension of the other end of the second cylinder 122.
The second extension 1232 is connected to an edge of the second top 1231, and the second extension 1232 extends toward the second base 120.
In a possible embodiment, the ratio between the size of the second cover 123 of at least one second hydrophobic structure 121 and the distance between two adjacent second hydrophobic structures 121 is not less than 1:2 and not more than 3: 5.
The second hydrophobic structure 121 in the above embodiments is the same as the first hydrophobic structure 111 of the lens 11 in the previous embodiments, and is not described herein again.
The second hydrophobic structure 121 provided in the foregoing embodiment can make the lens 11 or the hydrophobic membrane 12 have the effect of defogging and hydrophobicity, and this embodiment provides a method for manufacturing the mouth mirror 1 to manufacture the hydrophobic lens 11 or the hydrophobic membrane 12.
Based on the same inventive concept, the present application provides a method for manufacturing a mouth mirror 1, as shown in fig. 7, comprising steps S1-S4:
s1, depositing the first material layer 3 on the substrate 2, and patterning the first material layer 3 to obtain the first-state material structure 31.
Alternatively, the substrate 2 is glass. Since the hydrophobic film 12 and the lens 11 both have hydrophobic structures, a set of manufacturing methods can be used to obtain the lens 11 or the hydrophobic film 12 having hydrophobic structures by changing the substrate 2. The substrate 2 can be made of different materials according to the actual situation of the hydrophobic lens 11 or the hydrophobic membrane 12. For example, the glass with a metal reflective film plated on one side can be used as the substrate 2 for preparing the lens 11, and the transparent glass can be used for preparing the hydrophobic film 12.
In this step, the first material layer 3 is a material for preparing the first top 1131 of the first hydrophobic structure 111 or the second top 1231 of the second hydrophobic structure 121, the step is an initial state before etching, the substrate 2 is selected, and etching is performed to prepare for obtaining the first hydrophobic structure 111 or the second hydrophobic structure 121, and the structure obtained after step S1 is shown in fig. 8.
And S2, performing first etching on at least a part of the substrate 2 not covered with the first-state material structure 31, so that the substrate 2 forms a first-state blind hole 21.
In the present embodiment, after the first material layer 3 is patterned, some gaps are formed to expose a portion of the substrate 2. At least a portion of the substrate 2 not covered by the first-state material structure 31 is subjected to a first etching process, so that the substrate 2 forms a first-state blind via 21. The remaining first material layer 3, i.e. the first-state material structure 31, is used as the first top 1131 of the first hydrophobic structure 111 or the second top 1231 of the second hydrophobic structure 121, and the structure obtained after the step S2 is shown in fig. 9.
Alternatively, the etching method may include, but is not limited to, dry etching and wet etching. The dry etching includes light volatilization, gas phase etching, plasma etching and the like. Wet etching is a pure chemical reaction process, which means that chemical reaction between solution and pre-etching material is used to remove the part not masked by the masking film material for etching purpose. Because wet etching may etch away a little part of the substrate 2 masked by the masking film, if dry etching is adopted for the first etching, the thickness of the second etching is smaller than that of the first etching; if the first etching is wet etching, the thickness of the second etching may be equal to that of the first etching.
S3, depositing a second material layer 4 on the first-state material structure 31, on the substrate 2 and in the first-state blind via 21, and patterning the second material layer 4 to expose at least a portion of the substrate 2 at the bottom of the first-state blind via 21, and obtaining a second-state material structure 41.
In this step, a second material layer 4 is deposited on the second-state material structure 41 obtained in step S2, please refer to fig. 10. And patterning the second material layer 4 until at least a portion of the substrate 2 at the bottom of the first-state blind via 21 is exposed, and obtaining a second-state material structure 41, see fig. 11.
Alternatively, when the second etch completely etches away the corresponding second material layer 4 on the first-state material structure 31, the second-state material structure 41 may include the first-state material structure 31 and the second material layer 4 perpendicular to the first-state material structure 31.
Alternatively, when the second etch completely etches away the corresponding second material layer 4 on the first-state material structure 31 and etches part of the first-state material structure 31, the second-state material structure 41 may include part of the first-state material structure 31 and the second material layer 4 perpendicular to the first-state material structure 31.
Optionally, when the second etching is performed to etch only the second material layer 4 corresponding to the first-state blind hole 21 without etching the corresponding second material layer 4 on the first-state material structure 31, the second-state material structure 41 may include the first-state material structure 31, the second material layer 4 covering the first-state material structure 31, and the second material layer 4 perpendicular to the first-state material structure 31.
Alternatively, when the second etching etches the corresponding second material layer 4 on the first-state material structure 31 partially, the second-state material structure 41 may include the first-state material structure 31, a portion of the second material layer 4 covering the first-state material structure 31, and the second material layer 4 perpendicular to the first-state material structure 31.
This step is to prepare the first extension 1132 or the third extension 1232, and the structure obtained after the step S3 is shown in fig. 10.
And S4, performing second etching on at least part of the first-state blind holes 21 exposed on the substrate 2 to form second-state blind holes 22 in the first-state blind holes 21, and obtaining the first hydrophobic structure 111 or the second hydrophobic structure 121. The second etching is wet etching.
In this step, at least a portion of the first-state blind via 21 exposed in the substrate 2 obtained in step S3 is subjected to second etching, so that the second-state blind via 22 is formed in the first-state blind via 21, and the first hydrophobic structure 111 or the second hydrophobic structure 121 is obtained. Since the etching is not one-direction etching, the etching needs to be performed in two directions, namely, vertical and horizontal directions, and the second etching is wet etching.
In one possible embodiment, the depth of the first etching is less than the depth of the second etching.
Specifically, the first etching is to prepare the first extension 1132 or the third extension 1232, and the etching depth of the second etching needs to be greater than the first etching depth so as to penetrate the depth of the first extension 1132, thereby etching the substrate 2.

1. by preparing the lens 11 with the first hydrophobic structure 111, the lens 11 has the defogging hydrophobic effect, and is simple in structure, easy to operate and use, low in space cost and capable of being produced in a large scale. Disposable, avoid the difficult sterile problem of lens 11.
2.

The hydrophobic membrane 12 is disposable, the problem that a hydrophobic structure is difficult to disinfect is solved away, and the stomatoscope 1 with the hydrophobic membrane 12 is directly disinfected in the later stage.
