Referring to the construction of the litter box shown in fig. 1 and the base top view construction shown in fig. 2, the litter box generally comprises a litter box 10 and a base 20.
Wherein, the cat litter box 10 is provided with a pouring port 101 for discharging excrement, and the inside of the cat litter box 10 is further provided with a sieve plate 102 for separating cat litter and excrement wrapped with the cat litter. Further, a pinch prevention device control (not shown in FIG. 1) for the litter box is also provided inside the litter box 10.
With the base 20, a window 201 is provided thereon for receiving excrement, and a trash can (not shown in fig. 1 and 2) is provided inside thereof for collecting excrement. A set of anti-pinch device AA '(hereinafter referred to as a first anti-pinch device) is installed at the left edge of the window 201 for monitoring the sheltering object near the left edge of the window 201, and a set of anti-pinch device BB' (hereinafter referred to as a second anti-pinch device) is installed at the right edge of the window 201 for monitoring the sheltering object near the right edge of the window 201.
As can be seen from the above, the edge of the window monitored by the anti-pinch device AA and the edge of the window monitored by the anti-pinch device BB' are two opposite edges, and as shown in fig. 1 and 2, the two opposite edges are perpendicular to the direction of rotation of the litter box 10.
During the automatic cleaning process, the litter box 10 rotates continuously, the sieve plate 102 separates the litter from the litter-laden waste, and when the pouring opening 101 of the litter box 10 rotates to the position of the window 201 of the base 20, the litter-laden waste is discharged into the trash can of the base, and when the pouring opening 101 completely leaves the window 201, the discharging process is finished.
At present, in order to avoid the cat in the cat litter box 10, the cat foot stretches into the base window, the cat litter box 10 rotates and clamps the cat foot, in the rotation process of the cat litter box 10, whether a shielding object exists near the left edge of the anti-pinch device AA 'real-time monitoring window 201, whether a shielding object exists near the right edge of the anti-pinch device BB' real-time monitoring window 201, and when any anti-pinch device monitors the shielding object, the cat litter box 10 is controlled to stop rotating, so that the cat is prevented from being pinched.
However, although the anti-pinch device AA 'and the anti-pinch device BB' can prevent a cat from being pinched during the rotation of the litter box 10, if excrement does not completely fall into the trash can from the pouring opening 102, the excrement sometimes hangs on the edge of the window due to viscosity or is pinched between the edge of the pouring opening 102 and the edge of the window 201, the cat litter box stops rotating due to the fact that the anti-pinch device monitors the excrement, and then the excrement cannot be automatically cleaned, and the phenomenon that the machine stops rotating due to the fact that the excrement cannot be cleaned completely occurs.
In order to solve the problem of unclean excrement cleaning, the control logic of the anti-clamping device control device for the cat litter box is optimized on the basis of not changing the whole structure of the cat litter box, and the optimized control logic is as follows:
in the process of automatically cleaning the cat litter box 10 by rotating, under the condition that the cat litter box 10 rotates clockwise, if the first anti-pinch device monitors that a shielding object is arranged on the window 201 of the base, the cat litter box 10 is controlled to stop rotating; under the anticlockwise rotation condition of a cat litter section of thick bamboo 10, if the window 201 that the second anti-pinch device monitored the base has the shelter, then control cat litter section of thick bamboo stall.
The sheltering object monitored by the first anti-pinch device or the second anti-pinch device is hung at the edge of the base window or an object clamped between the edge of the cat litter box pouring opening and the edge of the base window.
The technical effects that can be achieved based on the above description are:
on the basis of not changing the whole structure and the original control logic of the cat litter box, the use logic of the anti-clamping device is optimized, namely when the rotation direction of the cat litter box is clockwise, the first anti-clamping device (used for monitoring the shielding object at the left edge of the base window) is used for monitoring the base window of the cat litter box to have the shielding object, and the cat litter box is controlled to stop rotating, so that when the pouring opening of the cat litter box just starts to rotate to the position of the base window, excrement wrapped by the cat litter can be more efficiently discharged into a garbage can arranged in the base from the cat litter box, and meanwhile, when the pouring opening of the cat litter box gradually rotates to deviate from the base window, a pet cat can be prevented from being injured; and when the rotation direction of cat litter section of thick bamboo is anticlockwise, there is the shelter through the base window of second anti-pinch device (being used for monitoring the shelter of base window right side border department) monitoring cat litter basin, control cat litter section of thick bamboo stall, like this can guarantee that the pouring opening of cat litter section of thick bamboo just begins to rotate to the base window position, the excrement of wrapping up in the cat litter can be followed cat litter section of thick bamboo and more efficiently arranged to the built-in garbage bin of base in, can prevent simultaneously that the pouring opening of cat litter section of thick bamboo from rotating when skew base window gradually, the pet cat is wounded.
Therefore, according to different rotation directions of the cat litter barrel, different anti-pinch devices are selected to monitor shelters near the edge of the corresponding base window, and the shelters are used as conditions for stopping rotation of the cat litter barrel, so that the phenomenon that excrement in the cat litter barrel cannot be discharged completely is reduced, unnecessary stop motion is avoided, the operation efficiency of the cat litter basin is improved, and meanwhile, when a cat is in the rotating cat litter barrel, cat feet stretch into the base window and are not pinched. It is noted that the non-selected anti-pinch devices may or may not be subject to occlusion monitoring.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The first embodiment is as follows:
fig. 3 is a schematic flow chart illustrating an embodiment of a method for controlling an anti-trap device for a litter box according to an exemplary embodiment of the present invention, the method is applicable to the litter box structure illustrated in fig. 1 and 2, and as shown in fig. 3, the method for controlling an anti-trap device for a litter box includes the following steps:
step 301: under the cat litter basin clockwise rotation circumstances, if first anti-pinch device monitors that there is the shelter at the base window of cat litter basin, then control cat litter section of thick bamboo stall.
Step 302: under the anticlockwise rotation condition of cat litter basin, if the base window that the second anti-pinch device monitored the cat litter basin has the shelter from when, control cat litter section of thick bamboo stall.
It can be understood by those skilled in the art that the steps 302 and 303 are two parallel steps, and there is no limitation on the execution order.
It should be noted that before executing step 301 or step 302, the triggering process for the cat litter box automatic cleaning control logic may include:
after the cat litter basin is connected with the power supply, whether there is the cat business turn over in the real-time detection cat litter section of thick bamboo, when detecting there is the cat business turn over, obtain the first weight of cat litter section of thick bamboo before the cat gets into and the second weight of cat litter section of thick bamboo after the cat goes out, and obtain the difference between first weight and the second weight, and then compare this difference and threshold value, if exceed the threshold value, explain that the cat leaves excrement (including excrement and urine, urine etc.) in cat litter section of thick bamboo, then begin to rotate according to the automatic control logic control cat litter section of thick bamboo that clears up of cat litter section of thick bamboo, in order to realize the automatic clearance function of cat litter section of thick bamboo.
Optionally, a gravity sensing element may be provided on the cat litter box to detect the action of the cat entering or exiting, and the weight of the cat litter box before the cat enters and after the cat exits.
Furthermore, an infrared sensing element can be arranged near the entrance on the cat litter barrel so as to detect the entrance and exit actions of the cat in combination with the gravity sensing element.
In an alternative embodiment, the rotation direction of the cat litter box can be obtained from the rotation direction of the motor in the cat litter box for the rotation of the cat litter box.
For example, if the motor is rotating clockwise, then the litter cartridge will correspondingly rotate in a clockwise direction, and if the motor is rotating counterclockwise, then the litter cartridge will correspondingly rotate in a clockwise direction.
In some alternative embodiments, the litter box auto purge control logic comprises:
firstly, determining the position of the cat sand cylinder, then calculating the rotation direction and the rotation time of the cat sand cylinder according to the position of the cat sand cylinder, and controlling the cat sand cylinder according to the calculated rotation direction and the calculated rotation time.
The cat litter box position refers to the angle of the access port on the cat litter box relative to the base. After the execution of the rotation direction and the rotation time of the cat litter cylinder is finished, namely the automatic cleaning is finished, the cat litter cylinder entry is ensured to be parallel to the base, so that a cat can freely enter and exit the cat litter cylinder. And in the process, in order to realize the purpose of pouring excrement into the garbage can of the base, the pouring opening of the cat sand cylinder and the window of the base are required to be completely overlapped at least once.
Further, in order to ensure that excrement is completely poured into the garbage can of the base, the pouring opening of the cat sand cylinder and the window of the base can be completely overlapped twice.
That is to say, the cat litter cylinder is controlled to rotate according to one direction firstly, so that the pouring opening and the base window are completely overlapped once, after the pouring opening of the cat litter cylinder leaves the base window along with the rotation, the cat litter cylinder is controlled to rotate according to the opposite direction, so that the pouring opening and the base window are completely overlapped once again, and the rotation is stopped until the entrance of the cat litter cylinder is parallel to the base.
Can know by the above-mentioned description, a cat litter section of thick bamboo can involve the rotation of equidirectional not in automatic clearance in-process, clockwise rotation and anticlockwise rotation promptly, consequently in the automatic clearance in-process of a cat litter section of thick bamboo, needs select corresponding anti-pinch device to monitor according to the rotation direction in real time.
It will be appreciated by those skilled in the art that the determination of the position of the litter box can be achieved using related art techniques, and the present application is not limited in this regard. For example, can set up a pair of opposite polarity's magnet and hall element on the cat litter section of thick bamboo, at the cat litter section of thick bamboo rotation process, hall element can be according to the position and the moment output cat litter section of thick bamboo position that detect two opposite polarity magnets.
So far, the control flow shown in the above fig. 3 is completed, and the invention, on the basis of not changing the whole structure of the litter box and the original control logic, by optimizing the use logic of the anti-pinch device, namely when the rotation direction of the litter box is clockwise, monitoring that the base window of the litter box has a shelter through the first anti-pinch device (used for monitoring the shelter at the left edge of the base window), and controlling the litter box to stop rotating, so that when the pouring opening of the litter box rotates to the position of the base window, the excrement wrapped with the litter can be more efficiently discharged from the litter box to the trash can arranged in the base; and when the rotation direction of cat litter section of thick bamboo is anticlockwise, there is the shelter through the base window of second anti-pinch device (being used for monitoring the shelter of base window right side border department) monitoring cat litter basin, and control cat litter section of thick bamboo stall, like this can ensure when the pouring opening of cat litter section of thick bamboo changes base window position, the excrement of wrapping up in the cat litter can be arranged to the built-in garbage bin of base more effectively from cat litter section of thick bamboo.
Therefore, according to different rotation directions of the cat litter box, different anti-clamping devices are selected to monitor shelters near the edge of the corresponding base window to serve as conditions for stopping rotation of the cat litter box, so that the phenomenon that excrement in the cat litter box cannot be discharged completely is reduced, unnecessary stopping actions are avoided, the operation efficiency of the cat litter box is improved, and meanwhile, cat feet can be prevented from stretching into the base window and being clamped and damaged when a cat is in the rotating cat litter box. It is noted that the non-selected anti-pinch devices may or may not be subject to occlusion monitoring.
The following specific description of the step 301 of selecting the first anti-pinch device to detect the occlusion condition is as follows:
referring to fig. 1 and 2, the initial position of the litter box when it is powered up is generally with the pour spout directly over, which facilitates the user's addition of litter, where the right edge of the pour spout is defined as the first edge, the left edge of the pour spout is defined as the second edge, and the first anti-pinch device is used to monitor the covering near the left edge of the base window, and the second anti-pinch device is used to monitor the covering near the right edge of the base window. When a cat litter section of thick bamboo rotates according to the clockwise, the first edge of pouring opening is at first tangent with base window right edge, then along with the rotation of a cat litter section of thick bamboo, the area of coincidence between pouring opening and the base window increases gradually, until the area of coincidence is the biggest, and when the first edge of pouring opening is tangent with base window left side edge, along with the rotation of a cat litter section of thick bamboo, the area of coincidence between pouring opening and the base window can reduce gradually, until there is not the area of coincidence completely.
According to the description, the first edge of the pouring opening is tangent to the right edge of the base window firstly, then the overlapping area between the pouring opening and the base window is gradually increased along with the rotation of the cat litter box, and in the process of the maximum overlapping area, because the space between the right edge of the base window and the first edge of the pouring opening is gradually increased, the cat litter box is not clamped even if a cat foot extends into the base window actually, and the overlapping area between the pouring opening and the base window is gradually increased until the overlapping area is maximum, the best discharge opportunity of the excrement in the cat litter box under the action of gravity is realized, and at the moment, the excrement at the pouring opening can easily shield the vicinity of the right edge of the base window. Therefore, the blocking condition detected by the second anti-pinch device for monitoring the blocking object near the right edge of the base window does not need to be used as a judgment condition for stopping the rotation of the litter box.
When the first edge of the pouring opening is tangent to the left edge of the base window, the overlapping area between the pouring opening and the base window can be gradually reduced along with the rotation of the cat litter box until the overlapping area is not formed, because the overlapping area between the pouring opening and the base window is gradually reduced, if objects such as cat feet and the like extend into the base window, the phenomenon of being clamped can occur, the blocking condition detected by the first anti-clamping device of the blocking object near the left edge of the base window needs to be monitored, the judging condition that the cat litter box stops rotating needs to be used as the judging condition, the overlapping time between the pouring opening and the base window is up, and at the moment, excrement in the cat litter box has enough time to be discharged into the garbage can of the base window.
Further, rotate the in-process at a cat litter section of thick bamboo clockwise, can close the second anti-pinch device to reduce system energy consumption.
In an optional specific implementation, under the condition that the first anti-pinch device is specifically a first infrared pair tube, the receiving and sending data between the first infrared pair tubes can be monitored in real time aiming at the process that the base window of the cat litter box is monitored through the first anti-pinch device to have the shielding object, and if the receiving and sending data are interrupted, it is indicated that an object is shielded near the left edge of the base window, and then the base window is determined to have the shielding object.
The interruption of data receiving and transmitting refers to the fact that data is transmitted by one infrared tube, and the other infrared tube on the other side cannot receive the data due to the fact that the data is shielded by an object, so that the interruption occurs.
It should be noted that, the above-mentioned first anti-pinch device adopts infrared pair tubes as an exemplary illustration only, which does not form a limitation to the scope of the present application, and the anti-pinch device may also be other sensing devices capable of detecting the blocking object.
In some alternative embodiments, it can be seen from the above analysis that the effective monitoring of the first anti-pinch device should begin with the first edge of the pour spout being tangent to the left edge of the base window, and the overlap area between the pour spout and the base window will gradually decrease until the process is completely misaligned, and in other processes, no object occlusion will occur near the left edge of the base window.
Based on this, as shown in fig. 4, when the edge monitored by the first anti-pinch device on the base window (i.e. the left edge of the base window) is tangent to the first edge of the pouring opening (i.e. the right edge of the pouring opening), the first anti-pinch device starts to monitor whether the base window of the cat litter box has a shelter or not, so as to further reduce the energy consumption of the system.
The monitoring element is arranged at the first edge of the pouring opening, the preset mark is arranged at the left edge of the base window, and when the monitoring element at the first edge of the pouring opening monitors the preset mark in the clockwise rotation process of the cat litter cylinder, the left edge of the base window is determined to be tangent to the first edge of the pouring opening.
The following description of the selection of the second anti-pinch device to detect the occlusion in step 302 is as follows:
referring to fig. 1 and 2 above, when the litter box rotates in a counterclockwise direction, the second edge of the pour spout is first tangent to the left edge of the base window, then the overlapping area between the pour spout and the base window gradually increases as the litter box rotates until the overlapping area is maximized, and when the second edge of the pour spout is tangent to the right edge of the base window, the overlapping area between the pour spout and the base window gradually decreases as the litter box rotates until there is no overlapping area.
According to the description, the second edge of the pouring opening is tangent to the left edge of the base window, then the overlapping area between the pouring opening and the base window is gradually increased along with the rotation of the cat litter box, and in the process of the maximum overlapping area, as the space between the left edge of the base window and the second edge of the pouring opening is gradually increased, even if a cat foot extends into the base window, the phenomenon of being clamped can not occur, and the overlapping area between the pouring opening and the base window is gradually increased until the overlapping area is maximum, the best discharge time of excrement in the cat litter box under the action of gravity is realized, and at the moment, the excrement at the pouring opening is easy to shield the vicinity of the left edge of the base window. Therefore, the shielding condition detected by the first anti-pinch device for monitoring the shielding object near the left edge of the base window does not need to be used as a judgment condition for stopping the rotation of the cat litter cylinder.
When the second edge of the pouring opening is tangent to the right edge of the base window, along with the rotation of the cat litter box, the overlapping area between the pouring opening and the base window can be gradually reduced until the overlapping area is not generated, because the overlapping area between the pouring opening and the base window is gradually reduced, if objects such as cat feet and the like extend into the base window, the phenomenon of being clamped occurs, the shielding condition detected by the second anti-clamping device for monitoring the shielding object near the right edge of the base window needs to be used as a judgment condition for stopping the rotation of the cat litter box, and the overlapping between the pouring opening and the base window is carried out for a period of time, at the moment, the excrement in the cat litter box has enough time to be discharged into the garbage can of the base window.
Further, at a cat litter section of thick bamboo anticlockwise rotation in-process, can close first anti-pinch device to reduce system energy consumption.
In an optional embodiment, under the second anti-pinch device specifically is the infrared geminate transistor condition of second, to the process that there is the shelter through the base window of second anti-pinch device monitoring cat litter basin, can real-time supervision second infrared geminate transistor between the receiving and dispatching data, if under the condition that the receiving and dispatching data appears interrupting, explain that there is the object shelter in near base window right edge, then confirm that the base window has the shelter from the thing.
The interruption of the data receiving and sending refers to the interruption of the data sending of one infrared tube, and the interruption occurs because the data is shielded by an object and the other infrared tube on the other side cannot receive the data.
It should be noted that, the above-mentioned second anti-pinch device adopts infrared pair tubes as an exemplary illustration only, which does not form a limitation to the scope of the present application, and the anti-pinch device may also be other sensing devices capable of detecting the blocking object.
In some alternative embodiments, it can be seen from the above analysis that the effective monitoring process of the second anti-pinch device should be started when the second edge of the pouring opening is tangent to the right edge of the base window, the overlapping area between the pouring opening and the base window will gradually decrease until there is no overlapping area, and in other processes, no object blocking will occur near the right edge of the base window.
Based on this, as shown in fig. 5, when the edge monitored by the second anti-pinch device (i.e. the right edge of the base window) on the base window is tangent to the second edge of the pouring opening (i.e. the left edge of the pouring opening), the second anti-pinch device can monitor whether the base window of the litter box has a shelter, so as to further reduce the energy consumption of the system.
The monitoring element is arranged at the second edge of the pouring opening, the preset mark is arranged at the right edge of the base window, and when the monitoring element at the second edge of the pouring opening monitors the preset mark in the anticlockwise rotation process of the cat litter cylinder, the right edge of the base window is determined to be tangent to the second edge of the pouring opening.
