Description

Technical Field

[0001] The utility model relates to the technical field of smart blackboards, in particular to an infrared smart blackboard with a cleaning device. Background Art

[0002] Infrared smart blackboards generally need to be installed with signal transmitting and receiving devices, and covered with filter strips. Just as the patent with patent number CN212624015U discloses an infrared touch screen, the filter strip covers the infrared lamp. However, during the long-term writing process on the blackboard, dust will fall on the filter strip. If it is not cleaned in time, it will easily affect the light transmittance of the filter strip and even cause the writing of the infrared smart screen to fail. Utility Model Content

[0003] In order to solve the problem in the prior art that dust easily affects the light transmittance of the filter strip, the utility model provides an infrared smart blackboard with a cleaning device which can clean the dust on the filter strip.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An infrared smart blackboard with a cleaning device, comprising:

[0006] Infrared smart screen, wherein a storage space for accommodating an infrared signal device is provided in front of the screen glass of the infrared smart screen, and the storage space is covered with a filter strip;

[0007] The moving part reciprocates relative to the infrared smart screen, and a cleaning device is provided on the moving part, and the cleaning device cleans the surface of the filter strip during the movement of the moving part.

[0008] Furthermore, the cleaning device includes a brush or a sponge.

[0009] Furthermore, the infrared smart blackboard also includes a push-pull sub-plate, the moving part is the push-pull sub-plate, and the push-pull sub-plate moves back and forth to cover or display the infrared smart screen.

[0010] Furthermore, the cleaning device is arranged at the end of the push-pull sub-plate.

[0011] Furthermore, the cleaning device is installed on the inner side of the push-pull sub-plate.

[0012] Furthermore, when the sliding sub-plate is located at the extreme position of being pushed open to display the infrared smart screen, the edge portion of the sliding sub-plate still covers the front of the infrared smart screen, and the cleaning device is installed on the inner side of this edge portion.

[0013] Furthermore, the infrared smart blackboard also includes a fixed sub-panel, which is located on at least one side of the infrared smart screen. The fixed sub-panel is biased outward relative to the screen glass of the infrared smart screen, and the sliding sub-panel always covers the junction between the infrared smart screen and the fixed sub-panel, thereby ensuring the aesthetics of the entire blackboard.

[0014] Furthermore, the infrared smart screen includes a frame, the frame is provided with a cavity for accommodating the infrared signal device, and the filter strip covers the cavity. The infrared signal device is installed in the cavity, and the filter strip covers the opening above the cavity, so the structure is more integrated and easy to install.

[0015] Furthermore, the frame is provided with a limiting groove, and the filter strip is stuck in the limiting groove, thereby ensuring the installation strength of the filter strip, and the filter strip will not be tilted or loosened due to the external force of the cleaning device.

[0016] Furthermore, a slide rail is fixedly connected to the frame, and the push-pull sub-plate slides along the slide rail. The slide rail is fixedly connected to the frame of the infrared smart screen, and the push-pull sub-plate slides along the slide rail, which ensures the movement accuracy of the push-pull sub-plate and ensures that the cleaning device located on the inner side of the push-pull sub-plate can always clean along the filter strip without movement deviation and causing a cleaning blind spot.

[0017] Beneficial effects:

[0018] (1) The utility model installs a cleaning device on the moving part, and uses the moving stroke of the moving part to clean the dust on the surface of the filter strip, thereby preventing the dust from affecting the light transmission ability of the filter strip;

[0019] (2) The cleaning device is integrated on the push-pull sub-plate, realizing the function of pushing and pulling the blackboard. At the same time, the movement of the push-pull sub-plate can also be used to clean the surface of the filter strip, killing two birds with one stone;

[0020] (3) The cleaning device is installed on the inner side of the sliding sub-plate to ensure the overall aesthetic performance;

[0021] (4) In the present invention, the infrared smart blackboard also includes a fixed sub-plate, which is biased outward relative to the screen glass of the infrared smart screen to reduce the height difference between the fixed sub-plate and the push-pull sub-plate. At this time, the fixed sub-plate is roughly aligned with the filter strip, and the push-pull sub-plate always covers the junction between the infrared smart screen and the fixed sub-plate during the movement, thereby ensuring the aesthetics of the entire blackboard. That is to say, when the push-pull sub-plate moves to the extreme position where it is pushed open to display the infrared smart screen, the edge of the push-pull sub-plate still covers the front of the infrared smart screen, which leaves installation space for the cleaning device, that is, the cleaning device is installed just on the inner side of this edge portion, thereby further ensuring the overall aesthetics while realizing the cleaning function;

[0022] (5) The infrared smart blackboard of the present invention includes a fixed sub-board, a push-pull sub-board and an infrared smart screen, which not only ensures the writing area, but also has the function of a smart blackboard and has good functionality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the utility model. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0031] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0034] like Figures 1 to 3 The utility model provides an infrared smart blackboard with a cleaning device, including an infrared smart screen 1 and a moving part: a storage space for accommodating an infrared signal device is provided in front of the screen glass of the infrared smart screen 1, and the storage space is covered with a filter strip 12, and the infrared signal device includes an infrared transmitting device and an infrared receiving device; the moving part reciprocates relative to the infrared smart screen 1, and a cleaning device 3 is provided on the moving part, and the cleaning device 3 cleans the surface of the filter strip 12 during the movement of the moving part. The moving part can be a separate moving frame or a sliding frame for mounting instruments or other parts. The cleaning device 3 can be a brush (preferably a hard brush) or a sponge (with a relatively large cleaning surface density) or other similar cleaning devices, as long as the surface of the filter strip 12 can be wiped or cleaned.

[0035] In the present invention, the infrared smart blackboard also includes a push-pull sub-plate 2, and the moving part is the push-pull sub-plate 2. The push-pull sub-plate 2 moves back and forth to cover or display the infrared smart screen 1. As an embodiment of the present invention, the cleaning device 3 is arranged at the end of the push-pull sub-plate 2, and the cleaning device 6 can be exposed. It only needs to be arranged above the filter strip 12, and the installation can be achieved through a mounting plate or a mounting frame. This installation method has no requirements for the travel of the push-pull sub-plate 2, and can also be applied to the situation where the infrared smart screen 1 can be fully displayed after the push-pull sub-plate 2 is pushed open.

[0036] As another embodiment of the present invention, the cleaning device 3 is installed on the inner side of the sliding sub-plate 2. This installation method is relatively more aesthetically pleasing.

[0037] When the sliding sub-panel 2 is in the extreme position of being pushed open to display the infrared smart screen 1, the edge of the sliding sub-panel 2 still covers the front of the infrared smart screen 1, and the cleaning device 3 is installed on the inner side of this edge. At this time, the cleaning device 3 is located above the end of the filter strip 12.

[0038] As another embodiment of the present invention, the infrared smart blackboard also includes a fixed sub-board 4, which is located on at least one side of the infrared smart screen 1, and the fixed sub-board 4 is biased outward relative to the screen glass 11 of the infrared smart screen 1, and the push-pull sub-board 2 always covers the junction between the infrared smart screen 1 and the fixed sub-board 4. The overall structure of this embodiment is relatively compact. Since the fixed sub-board 4 is biased outward relative to the screen glass 11 of the infrared smart screen 1 to reduce the drop between the fixed sub-board 4 and the push-pull sub-board 2, when the push-pull sub-board 2 is in the extreme position of being pushed open to display the infrared smart screen 1, the edge of the push-pull sub-board 2 still covers the front of the infrared smart screen 1, which leaves installation space for the cleaning device 3, that is, the cleaning device 3 is installed just on the inner side of this edge portion. On the one hand, the overall aesthetics is guaranteed, and on the other hand, there is no need to worry about the cleaning device 3 interfering with the fixed sub-board 4 biased outward relative to the screen glass 11.

[0039] Specifically, the infrared smart screen 1 includes a frame 13, a cavity 14 for accommodating the infrared signal device is provided on the frame 13, the filter strip 12 covers the opening above the cavity 14, and the frame 13 is provided with a limit groove, and the filter strip 12 is stuck in the limit groove. During installation, the filter strip 12 is inserted into the limit groove from one side, and the two ends are limited by the fixed sub-plates 4 fixed on both sides of the infrared smart screen 1.

[0040] The frame 13 is fixedly connected with a slide rail, and the push-pull sub-plate 2 slides along the slide rail. Since the fixed sub-plate 4 is fixed to the frame 13 of the infrared smart screen 1, the slide rail can also be fixed to the fixed sub-plate 4 at the same time, which can ensure the overall strength and movement accuracy.

[0041] In the present invention, the filter strip 12 is arranged in the horizontal direction, and correspondingly, the push-pull sub-plate 2 is also moved in the horizontal direction, mainly because the bottom filter strip 12 is easy to accumulate dust. According to actual needs, the present invention can also be applied to the situation where the filter strip 12 is arranged in the vertical direction and the push-pull sub-plate 2 is moved in the vertical direction.

[0042] As an application embodiment of the utility model, the infrared smart screen 1 is fixed with fixed sub-panels 4 on both sides, and correspondingly, includes two push-pull sub-panels 2. When the two push-pull sub-panels 2 are pushed to both sides at the same time, the two push-pull sub-panels 2 cover the corresponding fixed sub-panels at the same time, and the infrared smart screen 1 is displayed. When the two push-pull sub-panels 2 are pulled inward at the same time, the two push-pull sub-panels 2 are spliced ​​and cover the front of the infrared smart screen 1, and the fixed sub-panels 4 on both sides are displayed. In order to ensure aesthetics, the push-pull sub-panels 2 always cover the junction between the infrared smart screen 1 and the fixed sub-panel 4 during the push-pull process. In addition, brushes are installed on the two push-pull sub-panels 2, and the filter strips 12 below can be cleaned during the push-pull process.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
