Description

Technical Field

[0001] The present application belongs to the field of photographic equipment, and in particular to an anti-fog wiper. Background Art

[0002] Rainy and snowy weather is a taboo for most photographers. Therefore, whether it is raining or snowing, few people take photos outdoors.

[0003] This is mainly because in such weather conditions, the outdoor light is dim, which can easily affect the imaging of photographic equipment. What is more serious is that raindrops, snowflakes, etc. can easily fall on the lens and block it. Utility Model Content

[0004] The example of the present application provides an anti-fog wiper, which can be used to prevent the lens of a camera device from being disturbed or soaked by rain or snow, thereby ensuring the normal recording and the shooting effect.

[0005] The solution of this application example is implemented through the following contents.

[0006] Anti-fog wipers include:

[0007] The body comprises a shell wall and a lens rotatably mounted on the shell wall, wherein an air duct passing through the lens along a plane direction of the lens and communicating with the outside of the shell wall is arranged inside the shell wall;

[0008] an exhaust mechanism connected to the shell wall and configured to exhaust air through the air duct; and

[0009] The top cover is connected to the top of the exhaust mechanism to cover the body and the exhaust mechanism.

[0010] Preferably, the top cover is an umbrella-shaped structure.

[0011] Preferably, the anti-fog wiper further comprises a cornice connected to the edge of the top cover.

[0012] Preferably, the angle of the cornice relative to the edge is adjustable.

[0013] Preferably, the top cover is detachably connected to the exhaust mechanism.

[0014] Preferably, a blower is installed in the exhaust mechanism.

[0015] Preferably, the exhaust mechanism has a bottom plate and a cover plate, wherein the bottom plate is an integral structure with the shell wall, the cover plate is detachably connected to the bottom plate, and the blower is installed between the bottom plate and the cover plate.

[0016] Preferably, the anti-fog wiper further comprises a switch, which is arranged in the exhaust mechanism and is used to switch the blower to forward or reverse rotation.

[0017] Preferably, the shell wall is provided with a plurality of first air holes connected with the air duct and distributed in a discrete annular manner around the lens, the exhaust mechanism has second air holes connected with the air duct, and the exhaust mechanism draws air from the air duct through the second air holes.

[0018] Preferably, the lens has a first surface and a second surface along a thickness direction, and a waterproof film is attached to any one of the first surface and the second surface.

[0019] The anti-fog wiper of the utility model can be used to enable the photographing equipment to still be used in rainy and snowy weather so as to photograph high-quality materials.

[0020] During use, the lens of the anti-fog wiper can transmit light, so it can be used to take pictures. When rain and snow fall on the lens in rainy and snowy weather, the rotation of the lens can produce a centrifugal effect, so that the rain and snow are thrown away from the lens under the action of centrifugal force, so that the lens will not be covered, allowing normal shooting.

[0021] Furthermore, when the lens rotates at a high speed, the temperature of the air near the lens may increase, and combined with the melting, evaporation and condensation of rain and snow, fog may form on the lens. In this regard, by using an air duct, a defog effect can be achieved through a ventilation effect.

[0022] Furthermore, the use of a top cover can reduce rain and snow from falling onto the lens.

[0023] Therefore, the anti-fog wiper of the utility model can achieve better shooting effect of the equipment on rainy and snowy days. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] It should also be noted here that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0038] Please also read Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 .

[0039] Specifically, an anti-fog wiper 100 is proposed, including a body 101, an exhaust mechanism 103 and a top cover 102. Figure 1 shown.

[0040] The main body 101 has a shell wall 1011 and a lens 1012 .

[0041] The lens 1012 is rotatably mounted on the housing wall 1011. The rotation axis of the lens 1012 is the thickness direction thereof. For example, the lens 1012 is driven to rotate by a slewing support, or is driven by a motor and a gear. The lens 1012 can be a glass lens 1012, or a lens 1012 of other materials, preferably with a relatively high light transmittance.

[0042] In addition, since it is used in a rainy and snowy environment, rainwater on the surface of the lens 1012 may enter the cavity of the shell wall 1011 in large quantities during its rotation (because there is no waterproof design), thereby causing unnecessary troubles later. In view of this, a useful design is to set a water retaining strip on the shell wall 1011.

[0043] In order to further improve the waterproof and anti-fog effects of the lens 1012, a structural design may be made on the first surface and the second surface along the thickness direction of the lens 1012. For example, a waterproof film or an anti-fog film is attached to any one of the first surface and the second surface. The waterproof film or the anti-fog film may be a thin film with a hydrophobic material on the surface.

[0044] The body 101 is a roughly rectangular or square structure, and a split structural design can be adopted. The various parts constituting the body 101 can be spliced ​​and combined to cooperate with each other. For example, the body 101 has a main frame and has an internal cavity or channel. The body 101 also has a detachable pressure plate that can be connected by bolts. The lens 1012 can be installed in the position of the cavity or channel of the frame, and then limited to the body 101 by the pressure plate, and a space for the lens 1012 to rotate is reserved, as well as a corresponding drive device or structure for the lens 1012. The body 101 can be made of plastic, rubber or other appropriate materials.

[0045] In particular, the interior of the shell wall 1011 is provided with an air duct passing through the lens 1012 along the plane direction of the lens 1012 and communicating with the exterior of the shell wall 1011. The air duct can be used to prevent the air temperature from rising when the lens 1012 rotates, thereby preventing the formation of water vapor, and thus preventing the water vapor from condensing into fog.

[0046] The air duct may be provided by any intentionally designed and manufactured cavity in the shell wall 1011 of the body 101, or by a structure such as a pipe, a groove or a channel. Such a structure also makes it easier to guide and restrict the inlet and outlet of the channel, thereby making the airflow in the channel more controllable.

[0047] Alternatively, the channel may be wound and directed in a planned manner within the shell wall 1011 , so that the airflow within the channel can cover most areas of the lens 1012 , thereby helping to achieve a better anti-fogging effect.

[0048] In order to increase the circulation speed of the air flow in the channel and adjust the air flow in and out, an exhaust mechanism 103 is also provided in the anti-fog wiper 100. The exhaust mechanism 103 is connected to the shell wall 1011 of the body 101. The exhaust mechanism 103 is used to suck air from the air duct to exhaust air. Figure 2 and Figure 3 shown.

[0049] In order to improve the effect of preventing rain and snow, a top cover 102 is also provided in the anti-fog wiper 100. The top cover 102 is connected to the top of the exhaust mechanism 103, and also covers the body 101 and the exhaust mechanism 103. Therefore, rain and snow that can fall on the lens 1012 in a straight or oblique direction can be blocked by the top cover 102. More preferably, the top cover 102 reduces the amount of rain and snow falling on the lens 1012, thereby avoiding the exhaust mechanism 103 from operating at a high intensity, thereby reducing the possibility of damage to the exhaust mechanism 103.

[0050] The top cover 102 can have various suitable shapes, as long as it can cover the exhaust mechanism 103 and the body 101. For example, the top cover 102 can be hemispherical, conical, rectangular, etc. In the illustrated structure of the present invention, the top cover 102 is in the shape of an umbrella.

[0051] Further, in some optional examples, the anti-fog wiper 100 may also include an eaves plate 1021 connected to the edge of the top cover 102. The eaves plate 1021 can prevent rain and snow from falling from the edge of the cover plate 1032 onto the lens 1012. Therefore, the eaves plate 1021 can improve the prevention of rain and snow splashing or dripping onto the lens 1012 without excessively increasing the volume of the cover plate 1032.

[0052] The eaves 1021 may be made of the same material as the shell wall 1011, or may be made of a different material, such as metal or non-metal, for example, plastic, rubber or wood; in a more specific example, it may be an acrylic board or a rubber strip.

[0053] Preferably, the connection mode of the eaves 1021 and the top cover 102 is specially designed so that the angle of the eaves 1021 relative to the edge can be adjusted. For example, the eaves 1021 is connected to the top cover 102 through a thin aluminum plate. Alternatively, the eaves 1021 can be connected to the edge of the top cover 102 through a damped rotating shaft. By adjusting the angle of the eaves 1021, the splashing and dripping mode of rainwater along the eaves 1021 at the edge of the top cover 102 and the coverage area thereof can be changed.

[0054] In some cases, the top cover 102 can be detachably connected to the exhaust mechanism 103. Alternatively, in other examples, the top cover 102 is connected to the shell wall 1011, and a gap between the top cover 102 and the shell wall 1011 is reserved to allow for the configuration space of the exhaust mechanism 103. In such an example, the top cover 102 and the shell wall 1011 of the body 101 can be connected by using a support rod. The size of the gap between the top cover 102 and the shell wall 1011 can be adjusted by configuring different lengths of the support rods, so that the exhaust mechanism 103 of different volume sizes can be accommodated.

[0055] Alternatively, a plurality of limit arms 1022 are provided on the inner surface of the top cover 102, and are engaged with the outer surface of the housing (bottom plate 1031 and cover plate 1032) of the exhaust mechanism 103, such as Figure 4 and Figure 5 shown.

[0056] In order to facilitate exhaust through the channel of the body 101, a blower can be installed in the exhaust mechanism 103, which can be connected through a knob 1034 with a stud that penetrates the cover plate 1032. In other words, the blower can inject air into the channel of the body 101, and then flow out to the outside of the shell wall 1011. Alternatively, an exhaust fan can also be set in the exhaust mechanism 103. For example, the exhaust fan can draw air from the channel and then exhaust it.

[0057] That is to say, the external airflow can be injected into the channel by the fan, or the external airflow can enter the channel and then be drawn away by the fan.

[0058] As a better option, the fan in the exhaust fan can either inject air into the channel of the shell wall 1011 or remove air from the channel. Therefore, a circuit can be set or an appropriate fan can be selected so that it can rotate forward and backward. Then, through such a design, the rotation mode of the fan can be adjusted as needed, thereby controlling the flow mode or direction of the airflow relative to the channel.

[0059] In order to achieve such an effect of adjusting the rotation direction, the anti-fog wiper 100 may further include a switch, which is arranged in the exhaust mechanism 103 and is used to switch the blower forward or reverse. The switch can be used to switch the positive and negative poles of the power supply of the motor, thereby switching the phase of the power supply to achieve switching of the rotation direction. The switch can be an electronic switch or a mechanical switch.

[0060] The exhaust mechanism 103 may be a mechanism consisting of a housing and its internal devices, equipment or components. For example, the exhaust mechanism 103 has a housing consisting of a bottom plate 1031 and a cover plate 1032. In the housing, the bottom plate 1031 is an integral structure with the housing wall 1011, and the cover plate 1032 is detachably connected to the bottom plate 1031. When the cover plate 1032 is removed, the blower can be installed on the bottom plate 1031, and then the blower is covered by the cover plate 1032. In other words, the blower is installed between the bottom plate 1031 and the cover plate 1032.

[0061] And because the blower can suck or inject airflow relative to the channel of the shell wall 1011, the exhaust mechanism 103 is connected to the shell wall 1011. For example, the shell wall 1011 of the body 101 is provided with a through hole connected to the channel. And the through hole is connected to the internal cavity composed of the cover plate 1032 and the bottom plate 1031.

[0062] Correspondingly, the cover plate 1032 and the bottom plate 1031 of the exhaust mechanism 103 are provided with exhaust holes or air exhaust holes. Correspondingly, the shell wall 1011 of the body 101 is also provided with exhaust holes or air exhaust holes.

[0063] For example, since the size of the lens 1012 may be relatively large, in order to cover the area of ​​the lens 1012 as much as possible, the shell wall 1011 of the anti-fog wiper 100 may be provided with a plurality of first air holes 1013 that are connected to the air duct and are discretely distributed in an annular shape around the lens 1012. Correspondingly, the exhaust mechanism 103 has second air holes 1033 that are connected to the air duct (which may be provided on the bottom plate 1031 or the cover plate 1032).

[0064] Thus, the first air hole 1013, the passage and the second air hole 1033 can form a connected air flow from the outside to under the lens 1012, and from under the lens 1012 to the outside. Then, by such a structure, the exhaust mechanism 103 can inhale air from the air duct through the second air hole 1033 under one working condition.

[0065] In some improved examples, a resistance heating wire may be provided in the exhaust mechanism 103 to generate a hot air flow through heating, and then the hot air flow is blown into the channel of the shell wall 1011 of the main body 101 by a fan, thereby utilizing heating.

[0066] The photographing device for the anti-fog wiper 100 provided by the present application is applied, comprising a photographing lens and a lens 1012 of the anti-fog wiper 100 as described above placed in front of the photographing lens. The inner mirror surface of the lens 1012 is arranged toward the photographing lens; and the lens 1012 is larger than the photographing lens, so that the light entering the photographing lens will not be blocked by the wiper.

[0067] In the present invention, features described and / or illustrated for one embodiment may be used in the same manner or in a similar manner in one or more other embodiments, and / or combined with features of other embodiments or replace features of other embodiments.

[0068] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model embodiment may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
