Description

Technical Field

[0001] The present application belongs to the technical field of camera devices, and specifically relates to a camera. Background Art

[0002] With the development of science and technology, cameras are increasingly used in various fields. From daily life to professional film and television production, to security monitoring, cameras play a vital role.

[0003] However, in the related art, the camera includes a housing and a lens, the lens is directly arranged in the inner cavity of the housing, and a light-transmitting part is provided at a position opposite to the lens. With this design, if the seal of any part of the housing fails, water vapor will invade the inner cavity of the housing, and the water vapor adhering to the lens and the light-transmitting part will cause the lens and the light-transmitting part to fog. Therefore, with this design, the risk of fogging of the lens and the light-transmitting part is relatively high. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a camera that can solve the problem of high risk of fogging of the lens and the light-transmitting member in the related art.

[0005] An embodiment of the present application provides a camera, including:

[0006] A housing and a light-transmitting member, wherein the housing is provided with a mounting opening, the light-transmitting member is provided on the housing and covers the mounting opening, a sealed cavity is formed in the inner cavity of the housing, and the mounting opening is in communication with the sealed cavity;

[0007] A lens is arranged in the sealed cavity and faces the light-transmitting member.

[0008] In an embodiment of the present application, the housing is provided with a mounting opening, the light-transmitting member is provided within the housing and covers the mounting opening, a sealed cavity is formed within the inner cavity of the housing, and the mounting opening is in communication with the sealed cavity. In other words, a portion of the housing participates in forming the sealed cavity, and the lens is provided within the sealed cavity. As a result, the lens and the light-transmitting member will only fog if moisture enters the sealed cavity. In other words, if the seal of the portion of the housing not participating in forming the sealed cavity fails, the lens and the light-transmitting member are unlikely to fog. Moisture vapor must continue to enter the sealed cavity before the lens and the light-transmitting member can fog. Thus, the probability of the lens and the light-transmitting member coming into contact with moisture is low, thereby reducing the risk of fogging for both the lens and the light-transmitting member.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0032] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0033] The camera provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0034] Please refer to Figures 1 to 12 As shown, a camera is provided in an embodiment of the present application, including: a housing 100, a light-transmitting element 200 and a lens 500.

[0035] The housing 100 is provided with an installation opening, and the light-transmitting member 200 is provided on the housing 100 and covers the installation opening. The light-transmitting member 200 is, for example, a glass sheet. A sealed cavity 170 is formed in the inner cavity of the housing 100 , and the installation opening is communicated with the sealed cavity 170 .

[0036] The lens 500 is disposed in the sealed cavity 170 and faces the light-transmitting member 200. In a specific use process, light passes through the light-transmitting member 200 and is irradiated onto the lens 500, so that the lens 500 can capture an image.

[0037] In the embodiment of the present application, the housing 100 is provided with a mounting opening, and the light-transmitting member 200 is disposed on the housing 100 and covers the mounting opening. A sealed cavity 170 is formed within the inner cavity of the housing 100, and the mounting opening is in communication with the sealed cavity 170. That is, a portion of the housing 100 participates in forming the sealed cavity 170, and the lens 500 is disposed within the sealed cavity 170. As a result, the lens 500 and the light-transmitting member 200 will only fog if moisture enters the sealed cavity 170. In other words, if the seal of the portion of the housing 100 that does not participate in forming the sealed cavity 170 fails, the lens 500 and the light-transmitting member 200 are unlikely to fog. Moisture needs to continue to enter the sealed cavity 170 before the lens 500 and the light-transmitting member 200 can fog. In this manner, the probability of the lens 500 and the light-transmitting member 200 coming into contact with moisture is low, thereby reducing the risk of fogging of both the lens 500 and the light-transmitting member 200.

[0038] In another embodiment, reference Figure 1 As shown, the camera further includes a circuit board 310 and a first sealing member 400. The inner cavity of the housing 100 is provided with a first barrel 140, one end of which is connected to the housing 100. The circuit board 310 is disposed in the inner cavity of the housing 100, and covers the port of the first barrel 140 at one end facing away from the mounting port. The circuit board 310 is sealed with the first barrel 140 via the first sealing member 400. A portion of the housing 100, the light-transmitting member 200, the first barrel 140, the first sealing member 400, and the circuit board 310 together form a sealed cavity 170. With this arrangement, the circuit board 310 participates in forming the sealed cavity 170. As a result, fewer additional components are required to construct the sealed cavity 170, thereby simplifying the overall structure of the camera and reducing its cost.

[0039] In other optional embodiments, the camera may further include an additional cover plate, which, together with a portion of the housing 100, the light-transmitting member 200, the first cylindrical portion 140, and the first sealing member 400, forms a sealed cavity 170. In this case, the cover plate is, for example, disposed within the inner cavity of the housing 100, and covers a port on the end of the first cylindrical portion 140 facing away from the first portion, and is sealed with the first cylindrical portion 140 via the first sealing member 400.

[0040] In a further embodiment, reference Figure 1 and Figure 3As shown, the first seal 400 is an annular structure. The circuit board 310 and the first barrel 140 are spaced apart in the imaging direction of the lens 500. The first seal 400 is located between the circuit board 310 and the first barrel 140. The first seal 400 is in close contact with the circuit board 310. A first annular groove 410 is defined on the surface of the first seal 400 facing the first barrel 140. The end of the first barrel 140 facing away from the mounting opening extends into the first annular groove 410 and seals against the wall of the first annular groove 410. This arrangement increases the contact area between the first barrel 140 and the first seal 400, thereby improving the sealing effect of the sealed cavity 170.

[0041] Specifically, the groove wall of the first annular groove 410 includes, for example, a bottom wall, a first side wall and a second side wall. The first side wall is, for example, fitted with the outer wall of the first barrel portion 140, and the second side wall is, for example, fitted with the inner wall of the first barrel portion 140. The bottom wall is, for example, located between the first barrel portion 140 and the circuit board 310, and fits with both of them.

[0042] For further reference, Figure 4 As shown, the circuit board 310 is provided with, for example, an abutment portion 311. The surface of the abutment portion 311 facing the first seal 400 is, for example, a flat surface, and this surface is, for example, directly in contact with the first seal 400. With this arrangement, the entire first seal 400 is subjected to a relatively uniform force, thereby further improving the sealing effect between the circuit board 310 and the first barrel 140. Optionally, for example, a copper layer can be applied to a local area of ​​the circuit board 310 to form the abutment portion 311.

[0043] In other optional embodiments, the first annular groove 410 may not be provided on the surface of the first sealing member 400 facing the first barrel portion 140. In this case, the surface of the first sealing member 400 facing the first barrel portion 140 may be, for example, a flat surface, which is directly in contact with the first barrel portion 140, thereby achieving a sealed fit between the circuit board 310 and the first barrel portion 140.

[0044] In a further embodiment, reference Figure 1As shown, the inner wall of the housing 100 is provided with a connecting rib 160. The connecting rib 160 is located outside the first cylindrical portion 140 and is connected to the circuit board 310 via a threaded connector 320. The connecting rib 160 may be, for example, a connecting post. With this arrangement, the position where the circuit board 310 and the threaded connector 320 mate is located outside the sealed cavity 170. This position is not part of the cavity wall of the sealed cavity 170, eliminating the need to consider sealing issues at the position where the circuit board 310 and the threaded connector 320 mate. This simplifies the overall design of the camera and facilitates its processing and assembly. Furthermore, in this embodiment, the degree of pressure exerted by the circuit board 310 on the first sealing member 400 can be adjusted by rotating the threaded connector 320, thereby accommodating different sealing requirements. It is understandable that the greater the pressure of the circuit board 310 on the first seal 400, the tighter the first seal 400 fits against the circuit board 310 and the first barrel 140, thereby achieving a better sealing effect between the first seal 400 and the circuit board 310 and the first barrel 140.

[0045] Optional, reference Figure 1 As shown, the number of connecting ribs 160 is, for example, at least two, and each connecting rib 160 is, for example, spaced apart along the circumference of the first cylindrical portion 140. With this arrangement, the circuit board 310 and the housing 100 are connected via at least two connecting ribs 160, thereby ensuring a more reliable connection between the circuit board 310 and the housing 100. It should be noted that the number of connecting ribs 160 is not limited in the embodiments of the present application; in other embodiments, the number of connecting ribs 160 may be one.

[0046] In other optional embodiments, the connecting rib 160 may also be located in the inner cavity of the first barrel 140. In this case, the camera further includes a fourth seal, and the threaded connector 320 is sealed with the circuit board 310 through the fourth seal.

[0047] In another embodiment, reference Figure 1As shown, the camera further includes a second sealing member 600. A second barrel portion 150 is provided in the sealed cavity 170. The sealed cavity 170 communicates with the mounting port through the inner cavity of the second barrel portion 150. A portion of the lens 500 extends into the inner cavity of the second barrel portion 150. For example, the end of the lens 500 provided with the lens is extended into the inner cavity of the second barrel portion 150. The second sealing member 600 is provided in the inner cavity of the second barrel portion 150 and sleeved on the exterior of the lens 500. The end of the second sealing member 600 facing the light-transmitting member 200 is in sealing engagement with the light-transmitting member 200. This arrangement forms a secondary seal between the second sealing member 600 and the light-transmitting member 200. In this way, if the seal between the light-transmitting member 200 and the housing 100 fails, the contact area between the second sealing member 600 and the light-transmitting member 200 can still block moisture, thereby further reducing the probability of fogging of the light-transmitting member 200 and the lens 500. Specifically, the light-transmitting element 200 is connected to the housing 100 by gluing, for example, and the glue is used to achieve a sealed fit between the two.

[0048] In other optional embodiments, there may not be a sealing fit relationship between the second sealing member 600 and the light-transmitting member 200 . In this case, there is, for example, a gap between the second sealing member 600 and the light-transmitting member 200 .

[0049] In another embodiment, the second sealing member 600 is sealed with the lens 500, for example. In this configuration, when the sealing of the sealing cavity 170 fails, the contact position between the second sealing member 600 and the lens 500 can still block water vapor, thereby reducing the probability of the light-transmitting member 200 and the lens 500 coming into contact with water vapor.

[0050] In other optional embodiments, there may not be a sealing fit relationship between the second sealing member 600 and the lens 500 . In this case, there is, for example, a gap between the second sealing member 600 and the lens 500 .

[0051] In an optional embodiment, based on the sealing cooperation with the light-transmitting member 200 at one end of the second sealing member 600 facing the light-transmitting member 200, the second sealing member 600 is also sealed with the lens 500 to further reduce the probability of fogging of the light-transmitting member 200 and the lens 500.

[0052] In another embodiment, reference Figure 1 As shown, the second sealing member 600 is sealed with the second barrel portion 150. With this arrangement, water vapor cannot pass through between the second sealing member 600 and the second barrel portion 150, thereby further improving the sealing effect of the camera.

[0053] In other optional embodiments, there may not be a sealing fit relationship between the second sealing member 600 and the second barrel portion 150 . In this case, there is, for example, a gap between the second sealing member 600 and the second barrel portion 150 .

[0054] In a further embodiment, reference Figure 1 、 Figure 5 as well as Figure 6 As shown, the inner sidewall of the second sealing member 600 is provided with a first protrusion 610, which seals with the lens 500. The end of the second sealing member 600 facing the light-transmitting member 200 is provided with a second protrusion 620, which seals with the light-transmitting member 200. Compared to the second sealing member 600 as a whole, the first protrusion 610 and the second protrusion 620 are more susceptible to elastic deformation. As a result, under the action of a relatively small extrusion force, the second sealing member 600 can be tightly fitted with the lens 500 and the light-transmitting member 200, thereby more easily achieving a seal between the second sealing member 600, the lens 500, and the light-transmitting member 200. In addition, this arrangement reduces the extrusion force between the second sealing member 600 and the lens 500, making it easier to assemble and disassemble the second sealing member 600 from the lens 500. In addition, with such a configuration, it is only necessary to ensure the processing accuracy of the first convex portion 610 and the second convex portion 620 to ensure the sealing effect between the second seal 600 and the lens 500 and the light-transmitting member 200, thereby making the processing difficulty of the second seal 600 relatively small and the processing relatively convenient.

[0055] In other optional embodiments, the second sealing member 600 may not be provided with the first protrusion 610 and the second protrusion 620. In this case, the entire inner sidewall of the second sealing member 600 is sealed against the lens 500, for example, and the surface of the second sealing member 600 facing the light-transmitting member 200 is sealed against the light-transmitting member 200, for example, as a whole.

[0056] In a further embodiment, reference Figure 1 、 Figure 5 and Figure 6 As shown, the outer sidewall of the second sealing member 600 is for example provided with the third convex portion 630, and the third convex portion 630 is sealed with the second barrel portion 150. As mentioned above, compared to the second sealing member 600 as a whole, the third convex portion 630 is more likely to undergo elastic deformation, so that, under the effect of a smaller extrusion force, the second sealing member 600 and the second barrel portion 150 can be closely fitted, thereby the sealing between the second sealing member 600 and the second barrel portion 150 can be more easily achieved, and so provided, the extrusion force between the second sealing member 600 and the second barrel portion 150 is less, thereby making the disassembly and assembly between the second sealing member 600 and the second barrel portion 150 more convenient. Moreover, so provided, only the processing accuracy of the third convex portion 630 needs to be ensured, thereby making the sealing effect between the second sealing member 600 and the second barrel portion 150 more convenient, thereby making the processing difficulty of the second sealing member 600 less, and processing more convenient.

[0057] In another embodiment, reference Figure 1As shown, the second cylindrical portion 150 is provided with a limiting portion 151. The end of the second sealing member 600 facing away from the light-transmitting member 200 engages with the limiting portion 151 in the axial direction of the housing 100. This arrangement limits the movement of the second sealing member 600 away from the light-transmitting member 200, thereby improving the stability of the second sealing member 600.

[0058] In other optional embodiments, the second barrel portion 150 may not be provided with the limiting portion 151 . In this case, the second sealing member 600 may move in a direction away from the light-transmitting member 200 .

[0059] In another embodiment, reference Figure 1 as well as Figures 7 to 9 As shown, the camera also includes a cable 700. The housing 100 is provided with a cable hole 180. The cable hole 180 includes a first tapered section 181. The cross-sectional area of ​​the first tapered section 181 gradually increases as it moves away from the inner cavity of the housing 100. The cable 700 passes through the cable hole 180 and is provided with a first mating portion 710. The shape of the first mating portion 710 matches the shape of the first tapered section 181 and is disposed in the first tapered section 181. It should be noted that the cross-sectional area of ​​the first tapered section 181 refers to the area of ​​the cross section perpendicular to the axis of the first tapered section 181. The axis of the first tapered section 181 coincides with the axis of the cable hole 180.

[0060] In this embodiment, the shape of the first fitting portion 710 is adapted to the shape of the first conical section 181, and the first fitting portion 710 is also a conical structure. During the process of placing the first fitting portion 710 into the first conical section 181, the end with a smaller cross-sectional area of ​​the first fitting portion 710 first enters the end with a larger cross-sectional area of ​​the first conical section 181, so that the first fitting portion 710 can be placed into the first conical section 181 more conveniently and quickly.

[0061] In other optional embodiments, the wire hole 180 may include a cylindrical section instead of the first tapered section 181. The first mating portion 710 may be shaped to match the cylindrical section and disposed within the cylindrical section. In this case, the cross-sectional area of ​​the cylindrical section remains constant in a direction away from the inner cavity of the housing 100. It should be noted that the axis of the cylindrical section coincides with the axis of the wire hole 180, and the cross-sectional area of ​​the cylindrical section refers to the area of ​​the section perpendicular to the axis of the cylindrical section.

[0062] In a further embodiment, reference Figure 7 and Figure 8As shown, the side wall of the first mating portion 710 is provided with a first rib 711, which abuts against the inner wall of the first tapered section 181 to seal the gap between the first mating portion 710 and the inner wall of the first tapered section 181. During use, the first rib 711 elastically deforms, thereby achieving a sealed fit between the first mating portion 710 and the first tapered section 181, that is, sealing the gap between the first mating portion 710 and the inner wall of the first tapered section 181.

[0063] In this embodiment, it is only necessary to ensure the processing accuracy of the first rib 711 to achieve the sealing fit between the first matching portion 710 and the first cone section 181, thereby making the processing difficulty of the first matching portion 710 relatively low.

[0064] In other optional embodiments, the side wall of the first matching portion 710 may not be provided with the first rib 711. In this case, for example, the overall processing accuracy of the side wall of the first matching portion 710 needs to meet the preset requirements to ensure the sealing effect between the first matching portion 710 and the first cone section 181.

[0065] In a further embodiment, reference Figures 7 to 9 As shown, the inner wall of the cable hole 180 has a step portion 182, which is located at the first end of the first tapered section 181. The first end of the first tapered section 181 is the end of the first tapered section 181 facing the inner cavity of the housing 100. The step portion 182 and the first mating portion 710 are engaged with each other in the axial direction of the cable hole 180. In this arrangement, when the first mating portion 710 and the step portion 182 abut against each other, it indicates that the cable 700 is installed in place, thereby making installation of the cable 700 more convenient.

[0066] In other optional embodiments, the wire hole 180 may not be provided with the step portion 182 .

[0067] In a further embodiment, reference Figures 7 to 9 As shown, a second rib 712 is provided on a side of the first matching portion 710 facing the step portion 182 . The second rib 712 fits against the step portion 182 to seal the gap between the first matching portion 710 and the step portion 182 .

[0068] During specific use, the second rib 712 undergoes elastic deformation, thereby achieving a sealed fit between the first matching portion 710 and the step portion 182 , that is, achieving sealing of the gap between the first matching portion 710 and the step portion 182 .

[0069] In this embodiment, it is only necessary to ensure the processing accuracy of the second rib 712 to achieve the sealing fit between the first matching portion 710 and the step portion 182, thereby further reducing the processing difficulty of the first matching portion 710.

[0070] In other optional embodiments, the side wall of the first matching portion 710 may not be provided with the second rib 712. In this case, for example, the overall processing accuracy of the side of the first matching portion 710 facing the step portion 182 needs to meet the preset requirements to ensure the sealing effect between the first matching portion 710 and the step portion 182.

[0071] In a further embodiment, reference Figure 9 and Figure 10 As shown, the first conical section 181 is provided with a clamping portion 110, and the clamping portion 110 is provided with a guiding inclined surface 111. The first matching portion 710 can extend into the first conical section 181 through the guiding inclined surface 111, and the first matching portion 710 and the clamping portion 110 are matched in the upper limit direction of the axial direction of the wire hole 180.

[0072] In this embodiment, the first mating portion 710 presses against the engaging portion 110, causing the engaging portion 110 to elastically deform, thereby inserting the first mating portion 710 into the first tapered section 181. Once the first mating portion 710 is inserted into the first tapered section 181, the engaging portion 110 restricts movement of the first mating portion 710 away from the inner cavity of the housing 100, thereby securing the first mating portion 710 to the first tapered section 181. This indicates that in this embodiment, the first mating portion 710 can be inserted into the first tapered section 181 simply by elastically deforming the engaging portion 110. This allows for a relatively convenient and rapid fixation of the first mating portion 710.

[0073] For further reference, Figure 9 and Figure 10 As shown, the number of the clamping portions 110 is, for example, at least two, and the clamping portions 110 are spaced apart along the circumference of the first tapered section 181. In this arrangement, the first mating portion 710 engages with the at least two clamping portions 110 in the axial direction of the wire hole 180 to achieve a maximum position, thereby improving the stability of the first mating portion 710. Of course, in other embodiments, the number of the clamping portion 110 may also be one, and the present embodiment does not limit the number of the clamping portions 110.

[0074] In other optional embodiments, the first cone section 181 may not be provided with the clamping portion 110. In this case, the first matching portion 710 is fixed to the first cone section 181 by gluing, for example. In this case, a glue dispensing operation is required, and the glue needs to be cured.

[0075] In a further embodiment, reference Figures 7 to 9As shown, the cable passage hole 180 further includes a second tapered section 183, one end of which communicates with the inner cavity of the housing 100 and the other end communicates with the first end of the first tapered section 181. The cross-sectional area of ​​the second tapered section 183 gradually increases as it moves away from the inner cavity of the housing 100, and the maximum cross-sectional area of ​​the second tapered section 183 is smaller than the minimum cross-sectional area of ​​the first tapered section 181. A step 182 is formed between the second tapered section 183 and the first tapered section 181. The cable 700 is provided with a second mating portion 720, the shape of which matches that of the second tapered section 183 and is disposed within the second tapered section 183. With this arrangement, when the cable 700 is installed, the second mating portion 720 fits closely with the second tapered section 183, thereby increasing the contact area between the cable 700 and the cable passage hole 180 and improving the stability of the cable 700.

[0076] In other optional embodiments, the wire hole 180 may not include the second tapered section 183 , and the cable 700 may not include the second mating portion 720 .

[0077] In another embodiment, reference Figure 8 As shown, the first surface 713 of the first mating portion 710 is positioned toward the clamping portion 110 and is in contact with the clamping portion 110. The first surface 713 is tilted relative to the axis of the wire hole 180, and the distance between the first surface 713 and the axis of the wire hole 180 gradually increases as it moves away from the inner cavity of the housing 100. With this arrangement, the force applied by the clamping portion 110 to the first mating portion 710 has a component perpendicular to the axis of the wire hole 180. This component prevents the first mating portion 710 from moving closer to the axis of the wire hole 180, thereby improving the stability of the first mating portion 710.

[0078] Optional, reference Figure 8 As shown, when the axis of the wire hole 180 is vertically arranged, the angle between the first surface 713 and the horizontal line 900 is, for example, β, and β is an acute angle.

[0079] In other optional embodiments, the first surface 713 may also be perpendicular to the axis of the wire hole 180. In this case, when the axis of the wire hole 180 is vertically arranged, the first surface 713 is entirely horizontally arranged.

[0080] In another embodiment, reference Figure 1 、 Figure 11 as well as Figure 12 As shown, the camera further includes a third sealing member 800 , and the housing 100 includes a first sub-housing 120 and a second sub-housing 130 connected to each other, and the first sub-housing 120 has a mounting opening.

[0081] One of the first sub-housing 120 and the second sub-housing 130 is provided with a second annular groove 121. The third sealing member 800 includes an inner ring portion 810, an outer ring portion 820, and a connecting portion 830. The inner ring portion 810 and the outer ring portion 820 are connected by the connecting portion 830. The outer ring portion 820 is disposed in the second annular groove 121. The inner ring portion 810 is in contact with the inner wall of the first sub-housing 120 or the inner wall of the second sub-housing 130. The connecting portion 830 is located between the first sub-housing 120 and the second sub-housing 130 and is in contact with both. This arrangement increases the contact area between the third sealing member 800 and the first sub-housing 120 or the second sub-housing 130, thereby improving the sealing effect between the first sub-housing 120 and the second sub-housing 130.

[0082] As a specific implementation, the first sub-housing 120 is provided with a second annular groove 121 , for example. Accordingly, the inner annular portion 810 is in contact with the inner wall of the first sub-housing 120 .

[0083] In other optional embodiments, the third sealing member 800 may also include only the connecting portion 830. In this case, neither the first sub-shell 120 nor the second sub-shell 130 is provided with the second annular groove 121. The sealing between the first sub-shell 120 and the second sub-shell 130 is achieved by making the connecting portion 830 fit both the first sub-shell 120 and the second sub-shell 130.

[0084] In another embodiment, a desiccant is provided in the sealed cavity 170. The desiccant can absorb moisture in the sealed cavity 170, thereby further reducing the probability of the lens 500 and the light-transmitting member 200 coming into contact with moisture, thereby reducing the risk of fogging of the lens 500 and the light-transmitting member 200.

[0085] In other optional embodiments, no desiccant may be provided in the sealed cavity 170 .

[0086] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
