[0040] Figure 1 This is a schematic diagram illustrating a touch screen capture device according to an exemplary embodiment, such as... Figure 1 As shown, the touch screen capture device includes: a first camera 1 and a second camera 2.

[0041] In this embodiment of the present invention, the camera types of the first camera 1 and the second camera 2 are not limited. For example, the first camera 1 and the second camera 2 can be infrared cameras, depth cameras, etc., and both the first camera 1 and the second camera 2 can use narrowband filters (wavelength 850nm) to shield visible light interference.

[0042] The first camera 1 and the second camera 2 are both located on the outside of the range hood 4 above the stove 3, and the touch screen 5 is located on the stove 3. The first camera 1 is located on the first side of the outer wall of the range hood 4 facing the stove 3, and the second camera 2 is located on the second side of the outer wall. Both the first camera 1 and the second camera 2 face the touch screen 5. The first side and the second side are perpendicular to the third side of the outer wall, and the third side is parallel to the back panel of the range hood 4.

[0043] In this embodiment of the utility model, the type of touch screen 5 and its installation position on the stove are not limited. For example, the touch screen 5 can be a capacitive touch screen. To facilitate user operation, the touch screen 5 can be located on the symmetrical axis of the two gas stoves on the stove, near the center of the outer side of the stove, that is, the center of the stove edge closest to the user among the four sides of the stove. A touch screen mounting part can be provided on the stove 3 to accommodate the touch screen 5, preventing the touch screen 5 from protruding from the stove surface. To facilitate countertop cleaning, the touch screen 5 is located below the glass panel of the stove.

[0044] A range hood 4 is installed directly above the stove 3. The range hood 4 can be a top-mounted range hood or a side-mounted range hood. A first camera 1 and a second camera 2 are both mounted on the outer wall of the range hood 4 facing the stove 3. The first camera 1 is located on a first side of this outer wall, and the second camera 2 is located on a second side of this outer wall. For example, the first side can be the left side, and the second side can be the right side.

[0045] The shooting angles of the first camera 1 and the second camera 2 are both directed toward the touch screen 5. For example, the first camera 1 and the second camera 2 are both tilted downwards at a 45° angle to the horizontal plane to cover the touch area of ​​the touch screen, so that the first camera 1 and the second camera 2 can capture the touch screen image of the user issuing touch commands by touching the touch screen 5. The touch screen image includes the image of the user clicking on the touch point on the touch screen 5.

[0046] In an optional embodiment, the touch screen acquisition device further includes a touch screen controller. The touch screen controller can be disposed below the touch screen 5. The touch screen controller is electrically connected to the touch screen 5, the first camera 1, and the second camera 2. The touch screen 5 receives the touch points of the user and sends the touch points to the touch screen controller. The first camera 1 and the second camera 2 send the captured touch screen images to the touch screen controller. The touch screen controller receives the touch points sent by the touch screen 5 and the touch screen images sent by the first camera 1 and the second camera 2. The touch screen controller calibrates the touch points sent by the touch screen 5 through the touch screen images to correct the touch commands.

[0047] As described above, this embodiment, by setting a first camera and a second camera on both sides of the outer wall of the range hood facing the stove touch screen, can capture the touch screen image of the user touching the touch screen area on the stove. This allows for the calibration of touch points based on the captured touch screen image, thereby improving the touch accuracy of the touch screen under the stove glass. Furthermore, setting the first camera and the second camera on both sides of the outer wall enables multi-angle capture of the touch screen image, reducing the probability of touch screen capture failure due to capture angle issues and improving the success rate of touch screen capture.

[0048] In an optional embodiment, the touch screen acquisition device further includes: a first slide rail 6 and a second slide rail 7; the first slide rail 6 is disposed on a first side, and a first sliding member that slides along the first slide rail 6 is provided in the first slide rail 6, and a first camera 1 is disposed on the first sliding member; the second slide rail 7 is disposed on a second side, and a second sliding member that slides along the second slide rail 7 is provided in the second slide rail 7, and a second camera 2 is disposed on the second sliding member.

[0049] In this embodiment of the invention, the first slide rail 6 is disposed along the first side. Specifically, the length of the first slide rail 6 can be approximately equal to the length of the first side, extending from the front end to the rear end of the first side, to support the adjustment of the position of the first camera 1 within the range from the front end to the rear end of the first side; alternatively, the length of the first slide rail 6 can be approximately equal to half the length of the first side, extending from the front end to the middle of the first side, to support the adjustment of the position of the first camera 1 within the range from the front end to the middle of the first side. The first slide rail 6 can be installed on the inner wall or the outer wall of the first side. When the first slide rail 6 is installed on the inner wall of the first side, the end of the first sliding member extends out of the inner wall of the first side, so that the first camera 1 mounted on the first sliding member can capture images.

[0050] In this embodiment of the invention, the second slide rail 7 is disposed along the second side. Specifically, the length of the second slide rail 7 can be approximately equal to the length of the second side, extending from the front end to the rear end of the second side, to support the adjustment of the position of the second camera 2 within the range from the front end to the rear end of the second side; alternatively, the length of the second slide rail 7 can be approximately equal to half the length of the second side, extending from the front end to the middle of the second side, to support the adjustment of the position of the second camera 2 within the range from the front end to the middle of the second side. The second slide rail 7 can be installed on the inner wall or the outer wall of the second side. When the second slide rail 7 is installed on the inner wall of the second side, the end of the second sliding member extends out of the inner wall of the second side, so that the second camera 2 mounted on the second sliding member can capture images.

[0051] In this embodiment of the utility model, the lengths of the first side and the second side are equal, the lengths of the first slide rail 6 and the second slide rail 7 are equal, and they are symmetrically arranged.

[0052] As can be seen from the above, by setting the first slide rail 6 and the second slide rail 7 in this embodiment of the present invention, the positions of the first camera 1 and the second camera 2 on the side can be flexibly changed, thereby adjusting the acquisition angle of the touch screen and making the acquisition angle of the touch screen acquisition device more flexible to adapt to touch screens 5 in different positions.

[0053] In an optional embodiment, the touch screen acquisition device further includes: a linkage 8; the linkage 8 is a rod-shaped structure, one end of the linkage 8 is connected to a first sliding member, and the other end of the linkage 8 is connected to a second sliding member, and the linkage 8 is used to link the sliding of the first camera 1 and the second camera 2.

[0054] In this embodiment of the invention, the linkage member 8 is located between the first slide rail 6 and the second slide rail 7. The linkage member 8 is perpendicular to both the first and second slide rails. One end of the linkage member 8 can be connected to the first sliding member by fitting one end of the linkage member 8 into the middle of the first sliding member, and the other end of the linkage member 8 can be connected to the second sliding member by fitting the other end of the linkage member 8 into the middle of the second sliding member. When it is necessary to adjust the position of the first camera 1 and the second camera 2, the linkage member 8 can be moved to make the first camera 1 and the second camera 2 move and adjust synchronously along the slide rail. For ease of pushing, a movable part is also provided in the middle of the linkage member 8.

[0055] As can be seen from the above, in this embodiment of the utility model, by setting a linkage 8 to connect the first sliding member and the second sliding member, the sliding of the first camera 1 and the second camera 2 can be linked, making the position adjustment process of the first camera 1 and the second camera 2 more convenient.

[0056] In an optional embodiment, the touch screen acquisition device further includes: a first rotating member and a second rotating member; the head of the first sliding member is provided with a first mounting shaft, the first rotating member is sleeved on the first mounting shaft, the first rotating member rotates around the first mounting shaft, and the first camera 1 is fixed on the first rotating member; the head of the second sliding member is provided with a second mounting shaft, the second rotating member is sleeved on the second mounting shaft, the second rotating member rotates around the second mounting shaft, and the second camera 2 is fixed on the second rotating member.

[0057] In this embodiment of the invention, the bottom of the first rotating member is a hollow groove, and a plurality of first positioning teeth are arranged around the circumference of the hollow groove. The head of the first sliding member has a first mounting shaft with a first toothed structure that meshes with the plurality of first positioning teeth. After the first rotating member is assembled with the first mounting shaft, rotating the first rotating member allows the first positioning teeth and the first toothed structure to fix the current angle of the first rotating member, thus maintaining the current angle and consequently fixing the current shooting angle of the first camera 1. When it is necessary to adjust the angle of the first camera 1, rotating the first camera 1 changes the relative position of the inner wall of the hollow groove at the bottom of the first rotating member and the outer wall of the first mounting shaft. The interaction between the first positioning teeth and the first toothed structure maintains the current rotation angle of the first camera 1.

[0058] The rotation principle of the second rotating component is the same as above. Specifically, the bottom of the second rotating component is a hollow groove, and multiple second positioning teeth are arranged around the circumference of the hollow groove. The second mounting shaft at the head of the second sliding component has a second toothed structure that meshes with the multiple second positioning teeth. After the second rotating component is assembled with the second mounting shaft, rotating the second rotating component allows the second positioning teeth and the second toothed structure to fix the current angle of the second rotating component, thus maintaining the current angle and fixing the current shooting angle of the second camera 2. When it is necessary to adjust the angle of the second camera 2, rotating the second camera 2 changes the relative position of the inner wall of the hollow groove at the bottom of the second rotating component and the outer wall of the second mounting shaft. The interaction between the second positioning teeth and the second toothed structure keeps the second camera 2 at its current rotation angle.

[0059] As can be seen from the above, in this embodiment of the utility model, by setting a first rotating member and a second rotating member and fixing the first camera 1 and the second camera 2 on the first rotating member and the second rotating member respectively, the direction of the first camera 1 and the second camera 2 can be adjusted by rotating the first rotating member and the second rotating member, so that the camera direction of the first camera 1 and the second camera 2 can still face the touch screen 5 after the position of the first camera 1 and the second camera 2 is adjusted along the slide rail, thereby improving the adaptability of the first camera 1 and the second camera 2.

[0060] In an optional embodiment, a first mounting portion 9 and a second mounting portion 10 are provided on the outer wall. The first mounting portion 9 is located on a first side, and the second mounting portion 10 is located on a second side. Both the first mounting portion 9 and the second mounting portion 10 are recessed into the range hood 4. The first mounting portion 9 is used to accommodate the first slide rail 6, and the second mounting portion 10 is used to accommodate the second slide rail 7.

[0061] In this embodiment of the utility model, both the first mounting part 9 and the second mounting part 10 are groove-type structures. The first mounting part 9 is integrally formed with the first side, and the second mounting part 10 is integrally formed with the second side. The first slide rail 6 is installed at the bottom of the first mounting part 9, and the second slide rail 7 is installed at the bottom of the second mounting part 10. The lengths of the first mounting part 9 and the first slide rail 6 are equivalent, and the lengths of the second mounting part 10 and the second slide rail 7 are equivalent.

[0062] As can be seen from the above, in this embodiment of the utility model, by providing a first mounting part 9 and a second mounting part 10 that are recessed into the range hood 4 on the first side and the second side respectively, it is possible to facilitate the installation of the first slide rail 6 and the second slide rail 7 on the range hood 4 and prevent the first slide rail 6 and the second slide rail 7 from protruding from the outer wall of the range hood and affecting the use of the range hood.

[0063] In an optional embodiment, a first cover is provided on the outside of the first camera 1 to cover the first camera 1 to prevent oil fumes from contaminating the first camera 1; a second cover is provided on the outside of the second camera 2 to cover the second camera 2 to prevent oil fumes from contaminating the second camera 2.

[0064] In this embodiment of the utility model, the first cover and the second cover can be configured differently depending on whether the camera protrudes from the mounting part of the slide rail.

[0065] With the first camera 1 and the second camera 2 being relatively small and able to be accommodated within their respective mounting portions, a first cover is disposed outside the first mounting portion 9, completely covering the first mounting portion 9, its bottom first slide rail 6, and the first camera 1. Similarly, a second cover is disposed outside the second mounting portion 10, completely covering the second mounting portion 10, its bottom second slide rail 7, and the second camera 2. To prevent the first and second covers from obstructing the shooting of the first camera 1 and the second camera 2, both the first and second covers are transparent components.

[0066] When the first camera 1 and the second camera 2 are too large to be accommodated in their respective mounting parts, the first cover can be disposed outside the housing of the first camera 1 or outside the lens of the first camera 1, and the second cover can be disposed outside the housing of the second camera 2 or outside the lens of the second camera 2. To prevent the first cover and the second cover from obstructing the shooting of the first camera 1 and the second camera 2, both the first cover and the second cover are transparent components.

[0067] As can be seen from the above, in this embodiment of the present invention, by setting a first cover on the outside of the first camera 1 and a second cover on the outside of the second camera 2, the first camera 1 and the second camera 2 can be shielded, preventing external forces from damaging the cameras and avoiding the cameras from being polluted by oil fumes.

[0068] In an optional embodiment, the touch screen capture device further includes a third camera 11; the third camera 11 is disposed on a third side and is used to capture the touch screen facing the user.

[0069] In this embodiment of the present invention, the type of camera of the third camera 11 is not limited. For example, the third camera 11 may be an infrared camera, a depth camera, etc. The third camera 11 may use a narrow-band filter (wavelength 850nm) to shield visible light interference, and the third camera 11 is oriented towards the touch screen 5.

[0070] To facilitate the capture of the touch screen facing the user, the third camera 11 is set in the middle of the horizontal third side. Preferably, the third side can be the horizontal side closer to the user among the two horizontal sides of the range hood 4 facing the outer wall of the stove 3.

[0071] The third camera 11 is electrically connected to the touch screen controller. The third camera 11 sends the touch screen image it captures to the touch screen controller. The touch screen controller receives the touch screen image sent by the third camera 11. The touch screen controller combines the touch screen images captured by the first camera 1, the second camera 2 and the third camera 11 to calibrate the touch points sent by the touch screen 5 in order to correct the touch commands.

[0072] The specific method for correcting touch commands can be as follows: when there is no touch operation on the touchscreen, any of the aforementioned cameras updates the reference image in real time in the non-touch state; when the touchscreen is operated, the touch screen is captured by any of the aforementioned cameras, and the data is fused with the touch points sent by the touchscreen to correct the point position error. Here, during data synchronization and fusion, the timestamps of the image frame acquisition and the points sensed by the finger touching the touchscreen are aligned, and an affine transformation matrix between the camera image coordinate system and the physical coordinate system of the touchscreen is constructed.

[0073] As can be seen from the above, by setting a third camera 11 on the third side in this embodiment of the utility model, the touch screen can be captured from the direction facing the user, which further reduces the probability of touch screen capture failure due to the problem of the capture angle and improves the success rate of touch screen capture.

[0074] In an optional embodiment, a third mounting portion 12 is provided on the outer wall, and the third mounting portion 12 is located on the third side; the third mounting portion 12 is recessed into the range hood 4, and the third mounting portion 12 is used to accommodate the third camera 11; a third mounting shaft is provided at the bottom of the third mounting portion 12, a third rotating member is sleeved on the third mounting shaft, the third rotating member rotates around the third mounting shaft, and the third camera 11 is fixed on the third rotating member.

[0075] In this embodiment of the utility model, the third mounting part 12 has a groove structure, the third mounting part 12 is integrally formed with the third side, the third mounting part 12 is located in the middle of the third side, and the third mounting shaft is installed at the bottom of the third mounting part 12.

[0076] In this embodiment of the invention, the bottom of the third rotating member is a hollow groove, and a plurality of third positioning teeth are arranged around the circumference of the hollow groove. The head of the third sliding member has a third mounting shaft with a third toothed structure that meshes with the plurality of third positioning teeth. After the third rotating member is assembled with the third mounting shaft, rotating the third rotating member allows the third positioning teeth and the third toothed structure to fix the current angle of the third rotating member, thus maintaining the current angle and consequently fixing the current shooting angle of the third camera 11. When it is necessary to adjust the angle of the third camera 11, rotating the third camera 11 changes the relative position between the inner wall of the hollow groove at the bottom of the third rotating member and the outer wall of the third mounting shaft. The interaction between the third positioning teeth and the third toothed structure maintains the current rotation angle of the third camera 11.

[0077] As can be seen from the above, in this embodiment of the utility model, by setting a third rotating component and fixing the third camera 11 on the third rotating component, the direction of the third camera 11 can be adjusted by rotating the third rotating component, so that the third camera 11 can adapt to the touch screen at different positions. After the horizontal height of the range hood changes, the camera direction of the third camera 11 can still face the touch screen 5, thereby improving the adaptability of the third camera 11.

[0078] In an optional embodiment, a third cover is provided on the outside of the third mounting part 12, which is used to cover the third camera 11 to prevent oil fumes from contaminating the third camera 11.

[0079] In this embodiment of the utility model, the third cover can be configured differently depending on whether the third camera 11 protrudes from the third mounting part 12.

[0080] Since the third camera 11 is small enough to be fully accommodated within the third mounting portion 12, the third cover is disposed outside the third mounting portion 12, completely covering the third mounting portion 12 and the third camera 11 inside. To prevent the third cover from obstructing the shooting of the third camera 11, the third cover is a transparent component.

[0081] If the third camera 11 is too large to be fully accommodated in the third mounting portion 12, the third cover can be disposed outside the housing of the third camera 11 or outside the lens of the third camera 11. To prevent the third cover from obstructing the shooting of the third camera 11, the third cover is a transparent component.

[0082] As can be seen from the above, in this embodiment of the utility model, by providing a third cover on the outside of the third mounting part 12, the third camera 11 can be shielded, preventing external forces from damaging the camera and avoiding oil fume pollution to the camera.

[0083] Secondly, this utility model also provides a range hood, the outer surface of which is provided with the aforementioned touch screen acquisition device.

[0084] In this embodiment of the utility model, the range hood can be a side-suction range hood or a top-suction range hood, and the range hood is fixed to a wall or other supporting structure.

[0085] In this embodiment of the invention, the terms "module" or "unit" refer to a computer program or part of a computer program that has a predetermined function and works with other related parts to achieve a predetermined goal, and can be implemented wholly or partially using software, hardware such as processing circuitry or memory, or a combination thereof. Similarly, one or more processors or memories can be used to implement one or more modules or units.
