Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a whiteboard eraser 10 according to an embodiment of the present invention is used for erasing an electronic whiteboard. The whiteboard eraser 10 may erase a non-digital pattern, that is, a non-electronic pattern, on the electronic whiteboard (the erasing at this time is physical erasing, for example, when the outermost layer of the electronic whiteboard is a glass cover, the whiteboard eraser 10 may erase the non-digital pattern of the strokes of the chalk on the glass cover), and the whiteboard eraser 10 may also erase a digital pattern, that is, an electronic pattern, on the electronic whiteboard (the erasing at this time is electronic erasing, for example, the whiteboard eraser 10 may erase the digital pattern written on the touch panel of the electronic whiteboard by fingers, capacitive pens, and the like and displayed on the display panel of the electronic whiteboard). The whiteboard eraser 10 and the electronic whiteboard can form an eraser system for teaching or conference assistance.
Specifically, in this embodiment, the electronic whiteboard is a capacitive electronic whiteboard. The touch control principle of the capacitive electronic whiteboard is as follows: the electric charges on the electronic whiteboard are absorbed by touching the touch panel of the electronic whiteboard through fingers, capacitance pens and the like, and the capacitance value of the conductive film of the touch panel is changed, so that a touch instruction on the touch panel is recognized, touch operation is realized, and corresponding digital patterns are displayed on the display panel.
The whiteboard eraser 10 comprises a handheld portion 100, a wiping portion 200 and a conductive portion 300.
Wiping unit 200 and conductive unit 300 are connected to hand-held unit 100, respectively, wiping unit 200 performing physical wiping, and conductive unit 300 performing electronic wiping. In the present embodiment, the conductive part 300 and the wiping part 200 are disposed on the same side of the handheld part 100, so that physical wiping and electronic wiping can be performed simultaneously. The wiping section 200 and the conductive section 300 constitute a wiping module 10 a. Specifically, in the present embodiment, the wiping module 10a and the handheld portion 100 may be detachably connected. Thus, when the wiping module 10a composed of the conductive part 300 and the wiping part 200 is worn due to a long usage time, it is possible to facilitate a user to replace the wiping module 10 a.
The handheld portion 100 has a conductive performance and is directly connected to the conductive portion 300, so that when a user holds the handheld portion 100, the hand of the user is conducted to the conductive portion 300 through the handheld portion 100, and the conductive portion 300 can provide a range of action for the electronic whiteboard sensing whiteboard eraser 10 and the electronic whiteboard. The handheld portion 100 and the conductive portion 300 may be made of a conductive metal material or a non-conductive metal material.
Specifically, the handle 100 may be made of a metal material having a certain rigidity. The conductive part 300 may be made of a conductive material such as conductive cloth or conductive fiber, which has a conductive property, so that when the conductive part 300 directly contacts with the electronic whiteboard, not only the digital pattern can be effectively removed, but also the hard conductive part 300 can be prevented from damaging the electronic whiteboard. The wiping part 200 can be made of a flexible material such as cotton cloth or sponge with water absorption performance, so that not only can non-digital patterns be effectively removed, but also the hard wiping part can be prevented from damaging the electronic whiteboard.
In the present embodiment, the conductive portion 300 is connected to the wiping portion 200 and located at the edge of the wiping portion 200. In this way, the range of operation of the electronic whiteboard inductive whiteboard eraser 10 can be directly and accurately grasped according to the shape of the conductive portion 300. Specifically, in the present embodiment, the conductive part 300 surrounds the wiping part 200. More specifically, a surface of the conductive portion 300 away from the hand-held portion 100 is flush with a surface of the wiping portion 200 away from the hand-held portion 100. Thus, the conductive part 300 can directly contact with the touch panel of the electronic panel, and the induction of the conductive part 300 to the charges on the touch panel can be enhanced.
In other embodiments, as shown in fig. 2 and fig. 3, a surface of the conductive portion 300 away from the handheld portion 100 and a surface of the wiping portion 200 away from the handheld portion 100 may not be flush, that is, the conductive portion 300 may not directly contact the touch panel, as long as the distance between the conductive portion 300 and the touch panel is within a certain range, so that the conductive portion 300 can sense the charge on the touch panel. As shown in fig. 2, a receiving groove 210 is formed on a side of the wiping portion 200 close to the handheld portion 100, and the conductive portion 300 is received in the receiving groove 210. Specifically, in the present embodiment, the receiving groove 210 is an annular groove opened at the edge of the wiping portion 200.
Referring to fig. 3, in the present embodiment, the handheld portion 100, the conductive portion 300, and the wiping portion 200 may also be connected in sequence along one direction, and the conductive portion 300 and the wiping portion 200 are stacked, and at this time, the wiping portion 200 is thin enough to enable the conductive portion 300 to sense charges on the touch panel.
It should be noted that, in other embodiments, the handheld portion 100 may be omitted, and in this case, the charges on the electronic whiteboard can be directly sensed by the human hand through the conductive portion 300 to change the capacitance of the conductive film of the touch panel, so as to identify the touch command on the touch panel to implement the touch operation, and simultaneously display the corresponding digital pattern on the display panel.
When the whiteboard eraser 10 wipes the whiteboard, if the whiteboard receives touch sensing within the action range of the whiteboard eraser 10, the conductive part 300 wipes the digital patterns on the whiteboard in an electronic wiping manner, and the wiping part 200 wipes the non-digital patterns on the whiteboard in a physical wiping manner; if the electronic whiteboard ignores the touch sensing within the whiteboard eraser action range, the wiping part 200 wipes the non-digital patterns on the electronic whiteboard in a physical wiping manner.
Referring to fig. 6, in the process of wiping the electronic whiteboard by the whiteboard eraser 10, the wiping portion 200 contacts the electronic whiteboard, and the electronic whiteboard can sense the acting range of the whiteboard eraser 10 on the electronic whiteboard through the conductive portion 300, when the whiteboard eraser 10 wipes the water-soluble pattern on the electronic whiteboard, the wiping portion 200 needs to be in a wet state (as shown in fig. 4, the wiping portion 200 contains the cleaning liquid 20, and the cleaning liquid 20 may be water), the charge on the electronic whiteboard can be absorbed by the human hand through the wet wiping portion 200 and the conductive portion 300, a capacitance change is generated on the touch panel, and a touch sensing is generated within the acting range of the whiteboard eraser 10. At this time, in order to avoid false touch sensing caused by the wet wiping portion 200 when cleaning the electronic whiteboard, the processor in the electronic whiteboard can ignore touch sensing within the action range of the whiteboard eraser 10, that is, the touch sensing caused by the wet wiping portion 200 and the conductive portion 300, so as to avoid the risk of touch misjudgment occurring when the wet wiping portion 200 wipes the electronic whiteboard (for example, the gouache on the touch panel).
In addition, if the processor of the whiteboard receives touch sensing within the range of action of the whiteboard eraser 10, the whiteboard eraser 10 can not only erase non-digital patterns (for example, water-soluble gouache on the touch panel) on the touch panel of the whiteboard through the wet erasing portion 200, but also erase digital patterns on the display panel of the whiteboard through the conductive portion 300 and the wet erasing portion 200.
Similarly, when the whiteboard eraser 10 does not need to erase the water-soluble pattern on the electronic whiteboard, that is, when erasing the water-insoluble pattern, the erasing portion 200 does not need to be in a wet state, that is, when the erasing portion 200 is in a dry state, if the processor of the electronic whiteboard ignores the touch sensing within the action range of the whiteboard eraser 10, the dry erasing portion 200 may erase the non-digital pattern (water-insoluble gouache, easy erasing) on the touch panel, and when the processor of the electronic whiteboard receives the touch sensing within the action range of the whiteboard eraser 10, the whiteboard eraser 10 may erase the non-digital pattern (water-insoluble gouache, easy erasing) on the touch panel of the electronic whiteboard not only through the dry erasing portion 200, but also may erase the digital pattern on the display panel of the electronic whiteboard through the dry erasing portion 300.
Further, in this embodiment, as shown in fig. 1, the whiteboard eraser 10 further includes a processing unit 400 and a switching unit 500, where the switching unit 500 is configured to switch a processing state of a processor of the whiteboard and transmit a switching signal to the processor of the whiteboard through the processing unit 400, the processing state includes a first state and a second state, when the processing state of the whiteboard is in the first state, the whiteboard ignores the touch sensing within the range of action of the whiteboard eraser 10, and when the processing state of the whiteboard is in the second state, the whiteboard receives the touch sensing within the range of action of the whiteboard eraser 10. In this way, it can be determined by operating the switching unit 500 whether the processor of the electronic whiteboard receives or ignores the touch sensing within the action range of the whiteboard eraser 10, so as to implement whether the whiteboard eraser 10 wipes the non-digital patterns on the touch panel of the electronic whiteboard and the digital patterns on the display panel simultaneously, or wipes only the non-digital patterns on the touch panel of the electronic whiteboard.
Further, in this embodiment, the whiteboard eraser 10 further includes a regulating unit 600, the regulating unit 600 is configured to generate a virtual size having a different ratio from the actual size of the conductive portion 300 according to the actual size of the conductive portion 300, and transmit a virtual size signal to the processor of the electronic whiteboard through the processing unit 400, and the processor of the electronic whiteboard identifies the virtual size and generates a sensing area on the touch panel of the electronic whiteboard according to the virtual size, where the sensing area is consistent with the acting range of the whiteboard eraser. For example, as shown in fig. 5, the dummy size of the conductive part 300 may be 1 times (the first sensing region 30a), 2 times (the second sensing region 30b), or 3 times (the third sensing region 30c) of the actual size of the conductive part 300, and so on. In this way, when the whiteboard eraser 10 simultaneously erases the pattern on the touch panel and the digital pattern on the display panel of the electronic whiteboard, the erasing area of the whiteboard eraser 10 on the display panel can be enlarged by increasing the size of the sensing area 300a, and the erasing of the digital pattern on the display panel of the electronic whiteboard can be accelerated.
Further, in the present embodiment, the handheld portion 100 includes a handheld body 110 and a conductive handle 120, the wiping portion 200 is connected to the handheld body 110, the conductive handle 120 is disposed on a side of the handheld body 110 away from the wiping portion 200, and the conductive handle 120 is electrically connected to the conductive portion 300 through the handheld body 110. In this way, on the premise that the human hand can sense the charge on the touch panel of the electronic whiteboard, the user can conveniently perform the wiping operation of the electronic whiteboard by holding the whiteboard eraser 10 by the conductive handle 120. Specifically, in the present embodiment, the handheld body 110 includes a housing 111 and a conductive block 112, the conductive block 112 is disposed between the housing 111 and the wiping portion 200, and the conductive handle 120 is electrically connected to the conductive portion 300 through the conductive block 112.
Further, in the present embodiment, a chamber 111a is disposed in the housing 111, the chamber 111a is used for storing the cleaning liquid 20, and the cleaning liquid 20 may be water. In this way, when the cleaning liquid 20 is insufficient or inconvenient to take, the cleaning liquid 20 in the chamber 111a can be directly used to wet the wiping part 200, so as to wipe the patterns (gouache or non-gouache) on the touch panel of the electronic whiteboard completely through the wetted wiping part 200 (refer to fig. 4).
Further, in the present embodiment, the whiteboard eraser 10 further comprises a control unit 700, and the control unit 700 is configured to transfer the cleaning liquid 20 in the chamber 111a to the wiping portion 200. In this way, in the process of wiping the touch panel of the electronic whiteboard, the user can transfer the cleaning liquid 20 in the chamber 111a to the wiping portion 200 to wet the wiping portion 200, so as to wipe the pattern (gouache or non-gouache) on the touch panel. The control unit 700 may include a liquid spraying tube and a water spraying switch, and the cleaning liquid 20 in the chamber 111a may be delivered to the wiping part 200 through the liquid spraying tube by controlling the water spraying switch to be turned on.
