By way of example, fig. 2 is a schematic diagram illustrating a motion recognition probe on an intelligent cigarette maker according to an exemplary embodiment, and as shown in fig. 2, two motion recognition probes-a motion recognition probe 21 on the left side and a motion recognition probe 22 on the right side-may be disposed on the front panel 20 of the intelligent cigarette maker.

The control circuit board stores the corresponding relation between each target action and the instruction of the intelligent range hood, the instruction comprises a starting instruction, a shutdown instruction, a wind power adjusting instruction of the intelligent range hood and the like, and after the target action of the user is identified, the control circuit board can execute the instruction corresponding to the identified target action according to the corresponding relation.
The intelligent smoke machine can recognize a plurality of target actions of a user through at least two action recognition probes, then the intelligent smoke machine is controlled to execute recognized instructions corresponding to the target actions according to the corresponding relation between the pre-stored target actions and the instructions, the instructions comprise startup and shutdown instructions and wind power adjusting instructions, so that when oil stains, flour, seasonings and the like are stuck on hands of the user in the cooking process and the user cannot conveniently and directly operate keys of the smoke machine, the corresponding target actions can be made, the intelligent smoke machine is controlled to work through the target actions, and the surface of the smoke machine is prevented from being polluted.

Here, some intelligent cigarette machines will be provided with the display screen, and this display screen will show the intelligent menu and be used for instructing user's cooking step, and the user can control intelligent cigarette machine through the target action and turn over the page to show the menu when looking over this menu.
In a possible embodiment, step 101 in the above-mentioned control method of the intelligent cigarette machine may also be implemented as the following steps a1 and a 2.
In step a1, the motion recognition probe detects information as to whether or not the corresponding position of the motion recognition probe is blocked by an object.
In step a2, the target motion of the user is recognized based on the information as to whether the corresponding position of the motion recognition probe is blocked by an object.
Here, the motion recognition probe is used to recognize information whether the corresponding position of the motion recognition probe is blocked by an object, and the control circuit board may recognize a target motion of the user according to the information whether the corresponding position of each motion recognition probe is blocked by an object. For example, if the one-side action recognition probe detects that the corresponding position of the action recognition probe is shielded by an object for a preset time, the control circuit board may recognize the target action of the user as the hovering action on the one side of the action recognition probe.
In one possible embodiment, the motion recognition probe includes any one of a camera, an infrared sensor, and an ultrasonic sensor; for example, when the motion recognition probe is a camera, whether the corresponding position is blocked by an object can be determined through a shot image; when the motion recognition probe is an infrared sensor, whether the corresponding position is shielded by an object can be determined by sensing infrared rays radiated by a target; when the motion recognition probe is an ultrasonic sensor, whether the corresponding position is shielded by an object can be determined by receiving an ultrasonic signal reflected by the target object.
In a possible embodiment, the distance between the motion recognition probe on the first side and the motion recognition probe on the second side is not easy to be too small, so as to prevent the motion recognition probes on the two sides from being recognized by mistake, and the distance between the motion recognition probe on the first side and the motion recognition probe on the second side is not easy to be too large, so that the gesture range of a user is prevented from being too large and the operation is not easy to be performed. Therefore, it is preferable that the distance range between the first side motion recognition probe and the second side motion recognition probe includes 200mm to 800 mm.
In a possible embodiment, the step a2 in the control method of the intelligent cigarette machine described above may also be implemented as the following steps a21 to a 24.
In step a21, when the object detected by the one motion recognition probe is occluded, the first timer is started, and when the first occluded time period between the occlusion of the object detected by the one motion recognition probe and the detection of the non-occlusion of the object is recorded, the first timer is ended.
In step a22, the second time measurement is started when the first time measurement is finished, and the second time measurement is finished when a delay time period is recorded between the detection by the motion recognition probe on the one side that is not blocked by the object and the detection by the motion recognition probe on the other side that is blocked by the object.
In step a23, the third time measurement is started when the second time measurement is finished, and the third time measurement is finished when the second occluded time period is recorded until the occlusion by the object detected by the other motion recognition probe is not detected.
In step a24, when the first and second occluded durations are both within a first preset duration range and the delay duration is within a second preset duration range, the target action is identified as a hand-waving action in the target direction.
Here, the motion recognition probes on both sides can detect whether or not they are hidden by an object, and a MCU (micro control Unit) and a timer are provided in the control circuit board.
Here, when the user swings his hand from one side to the other side, the hand of the user is positioned in front of the motion recognition probe on the one side to shield the motion recognition probe on the one side, and then swings to the front of the motion recognition probe on the other side after a while to shield the motion recognition probe on the other side. When the control circuit board identifies the waving hand from one side to the other side, the timer can sequentially count time for three times, record the first shielded time length from the time when the motion recognition probe at one side detects that the motion recognition probe at one side is shielded by the object to the time when the motion recognition probe at one side detects that the motion recognition probe at the other side is not shielded by the object to the time when the motion recognition probe at one side detects that the motion recognition probe at the other side is shielded by the object; and the action recognition probe on the other side detects a second shielded time period from the shielding of the object to the non-shielding of the object. And if the timing is sequentially finished for three times, the first shielded duration and the second shielded duration are both within the first preset duration range, and the delay duration is within the second preset duration range, indicating that the user is a hand waving action from one side to the other side. Of course, if only one or two times of timing are completed, it indicates that the user is not performing the hand-waving motion.
Here, when the one side is a first side and the other side is a second side, the target direction is a first direction, when the one side is a second side and the other side is a first side, the target direction is a second direction, in this embodiment, the first side is a left side and the second side is a right side, and then the target direction is a first direction from left to right or a second direction from right to left.
For example, taking one side as the left side and the other side as the right side as an example, the first preset time period ranges from 10ms to 500ms, and the second preset time period ranges from 200ms to 5000 ms. When the left motion recognition probe detects the occlusion by the object, the timer starts to count for the first time to obtain a first occluded time length t1 (the first counting is from the beginning of the occlusion by the left motion recognition probe to the end of the restoration to the non-occluded state), when the left motion recognition probe returns to the non-occluded state, the timer starts to count for the second time to obtain a time length t2 (the second counting is from the beginning of the restoration to the non-occluded state by the object to the end of the recognition to the occlusion by the right motion recognition probe), when the right motion recognition probe recognizes the occlusion by the object, the timer starts to count for the third time to obtain an occluded time length t3 (the third counting is from the beginning of the detection by the object to the end of the restoration to the non-occluded state by the object by the left motion recognition probe), if the conditions that 10ms is not less than t1/t3 not less than 500ms and that 200ms is not less than t2 not less, the MCU of the control circuit board determines that the current target motion is a left-to-right hand waving motion. The hand waving motion from right to left is similar to the above determination and will not be described again.
It should be noted that the second preset time length range may be determined according to a distance range between the motion recognition probe on the first side and the motion recognition probe on the second side, and if the distance between the probes on the two sides is larger, the second preset time length may be correspondingly set to be larger.
In a possible embodiment, the step a2 in the control method of the intelligent cigarette making machine described above can also be implemented as the following step a 25.
In step a25, when the first occluded duration is within the first preset duration range, the delay duration is within a second preset duration range, and the second occluded duration is within a third preset duration range, the target motion is identified as the waving hovering action in the target direction.
Here, the duration in the third preset duration range is greater than the duration in the first preset duration range.
Still taking one side as the left side and the other side as the right side as an example, the first preset time range is 10ms to 500ms, the second preset time range is 200ms to 5000ms, the third preset time range includes more than or equal to 500ms, when the motion recognition probe on the left side detects the occlusion by the object, the timer starts to count for the first time to obtain a first occluded time t1 (the first time starts from the detection of the occlusion by the object by the motion recognition probe on the left side to end to recover to the non-occluded state again), when the motion recognition probe on the left side recovers to the non-occluded state, the second time starts to count for the second time to obtain Δ t2 (the second time starts from the recovery of the motion recognition probe on the left side to the non-occluded state by the object to the recognition of the object by the motion recognition probe on the right side), the timer starts to count for the third time when the motion recognition probe on the right side recognizes the occlusion by the object, obtaining the shielded time length t3 (the third time is from the beginning of the detection of the left motion recognition probe by the object shielding to the end of the restoration of the left motion recognition probe to the end of the non-shielding by the object shielding), if the conditions that the t1 is more than or equal to 10ms and less than or equal to 500ms and the 200ms is more than or equal to delta t2 is more than or equal to 5000ms ANDt3 is more than or equal to 500ms are met, the MCU of the control circuit board judges that the current target motion is the hovering motion after waving from. The operation of swinging the hand backward from right to left is similar to the above determination, and is not described again.
In a possible embodiment, the step a2 in the control method of the intelligent cigarette machine described above may also be implemented as the following steps a26 and a 27.
In step a26, a third occluded period from occluded to unoccluded by the object detected by the motion recognition probe on one side is determined.
In step a27, when the third occluded duration is within a fourth preset duration range, identifying the target action as a hover action of the target location, where the hover action of the target location is a hover action of a first side location when the side is a first side, and the hover action of the target location is a hover action of a second side location when the side is a second side. .
Here, taking the left side as an example, the third preset time range includes a time period of 500ms or more, and when the motion recognition probe on the left side recognizes that the object is occluded, the timer starts to count time to obtain a third occluded time period t4(t4 is a time period from when the motion recognition probe on the left side detects that the object is occluded to when the motion recognition probe returns to the unoccluded state again), and when t4 is equal to or more than 500ms, it is determined that the target motion of the user is the left-side hovering motion. The right-side hovering action is similar to the judgment, and is not described in detail.
It should be noted that the duration in the third preset duration range is longer than the duration in the first preset duration range.
In one possible embodiment, step 102 in the above-described control method of the intelligent range hood may also be implemented as the following steps B1 and B2.
In step B1, in the standby state of the intelligent range hood, when the target action is the hovering action of the first side position, the intelligent range hood is controlled to execute an instruction for starting the operation of the weak wind mode.
In step B2, in the standby state of the intelligent range hood, when the target action is a hovering action of the second side position, controlling the intelligent range hood to execute an instruction for starting a strong wind mode operation.
Here, the hover action at the first side position corresponds to an instruction to initiate a weak wind mode operation, and the hover action at the second side position corresponds to an instruction to initiate a strong wind mode operation.
For example, taking the first side as the left side and the second side as the right side as an example, when a user wants to control the intelligent cigarette making machine to start the operation in the weak wind mode, the user may extend a hand to the motion recognition probe on the left side, and a duration of shielding the motion recognition probe on the left side exceeds 500ms in a fourth preset duration range, then the control circuit board may determine, by using a timer, that a third shielded duration t4 from having an object shielded to not being shielded by the object, detected by the motion recognition probe on the left side exceeds 500ms, and in the fourth preset duration range, the MCU of the control circuit board may determine that a target motion of the user is a hovering motion on the left side, and at this time, the MCU may control the intelligent cigarette making machine to execute an instruction of starting the operation in the weak wind mode.
Of course, if the user wants to control the intelligent range hood to start the strong wind mode, the user can extend the hand to the right motion recognition probe, and the time length for shielding the right motion recognition probe is within the fourth preset time length range, for example, more than 500 ms. The specific detection and control process of the control circuit board may be as described above, and will not be described in detail. At the moment, the MCU of the control circuit board can determine the target action of the user as the hovering action on the right side, and at the moment, the MCU can control the intelligent smoke machine to execute an instruction for starting the strong wind mode to work.
In a possible embodiment, the step 102 in the control method of the intelligent cigarette machine described above can also be implemented as the following step B3.
In step B3, in the power-on state of the intelligent cigarette making machine, when the target action is a hovering action that simultaneously identifies a first side position and a second side position, controlling the intelligent cigarette making machine to execute an instruction for closing the intelligent cigarette making machine.
Here, the simultaneous hovering action of the two side positions corresponds to an instruction to turn off the intelligent cigarette making machine.
For example, taking the first side and the second side as the left side and the right side as an example, when the user wants to close the smart cigarette maker, the user may extend the left hand and the right hand to the left motion recognition probe and the right motion recognition probe respectively, and simultaneously shield the left motion recognition probe and the right motion recognition probe, and the shielding duration is within a fourth preset duration range, for example, exceeds 500ms, the control circuit board may determine, by using the timer, that a third shielded duration t4, which is detected by the left motion recognition probe and is shielded by an object, exceeds 500ms from the time when the object is shielded to be not shielded by the object, and that a third shielded duration t4, which is detected by the right motion recognition probe and is shielded by the object, exceeds 500ms, the MCU of the control circuit board determines the target motion of the user as a hovering motion for simultaneously recognizing the position of the first side and the position of the second side, at this time, the MCU can control the intelligent cigarette machine to execute an instruction for closing the intelligent cigarette machine.
In one possible embodiment, step 102 in the above-described control method of the intelligent range hood may also be implemented as the following steps B4 and B5.
In step B4, in the powered-on state of the intelligent range hood, when the target motion is a hand waving motion in the first direction, the intelligent range hood is controlled to execute an instruction of turning down the air volume.
In step B5, in the powered-on state of the intelligent range hood, when the target motion is a hand waving motion in the second direction, the intelligent range hood is controlled to execute an instruction for increasing the air volume.
Here, in the cooking process, the user sometimes needs a larger air volume to smoke vigorously, and sometimes needs only a smaller air volume to smoke vigorously, so it is necessary to set some correspondence between the target operation and the air volume adjustment command so that the user can adjust the air volume by the target operation. In this embodiment, an instruction for decreasing the air volume corresponding to the hand waving motion from the left to the right direction may be set, and an instruction for increasing the air volume corresponding to the hand waving motion from the right to the left direction may be set.

In step B7, in the power-on state of the intelligent cigarette making machine, when the target motion is a hand-waving hovering motion in a second direction, controlling the intelligent cigarette making machine to execute an instruction of turning up one page from the current page of the display screen.
Here, the intelligent cigarette making machine is provided with a display screen, the display screen can display an intelligent menu, and when a user uses the intelligent menu in a cooking process, the user needs to turn pages back and forth to check the menu, so that some corresponding relations between target actions and air volume adjusting instructions can be set, so that the user can adjust the air volume through the target actions.
For example, taking the first side as the left side and the second side as the right side as an example, when a user wants to turn down a page from the current page, the user can swing the hand from the motion recognition probe on the left side to the motion recognition probe on the right side and suspend the hand for a period of time, the control circuit board can time for three times by using the timer to obtain a first sheltered duration, a delay duration and a second sheltered duration, and the MCU of the control circuit board determines that the target motion of the user is a hover motion after swinging the hand from left to right within the first sheltered duration, where the delay duration is within a second preset duration range and the second sheltered duration is within a third preset duration range, and at this time, the MCU can control the intelligent cigarette making machine to execute an instruction to turn down a page from the current page of the display screen. Of course, if the user wants to turn up a page from the current page, the user can swing the hand from the right side action recognition probe to the left side action recognition probe, at this time, the MCU of the control circuit board can determine the target action of the user as the action of hovering after swinging the hand from right to left as described above, and at this time, the MCU can control the intelligent cigarette making machine to execute an instruction of turning up a page from the current page of the display screen.
It should be noted here that in some other embodiments, an instruction for turning down the air volume corresponding to the hover action after waving in the first direction from the first side to the second side may be further set, and an instruction for increasing the air volume corresponding to the hover action after waving in the second direction from the second side to the first side may be further set; the manual waving action in the left-to-right direction is set to correspond to an instruction to turn down one page from the current page of the display screen, and the manual waving action in the right-to-left direction is set to correspond to an instruction to turn up one page from the current page of the display screen, which is not limited herein.

When the intelligent range hood is in the starting state, the hand waving action in the first direction or the second direction corresponds to an instruction for closing the intelligent range hood. The hovering action at the first side position corresponds to an instruction for reducing the air volume, and the hovering action at the second side position corresponds to an instruction for increasing the air volume. And setting a back-swipe motion in a first direction from the first side to the second side to be responsive to an instruction to flip a page down from a current page of the display screen, and setting a back-swipe motion in a second direction from the second side to the first side to be responsive to an instruction to flip a page up from the current page of the display screen.
