As shown in fig. 5, 6, 7, 8, and 9, the detecting device 160 includes a first camera 161, a first weight sensor 162, a hall switch 164, a first infrared sensing switch 165, and a second infrared sensing switch 166, wherein the hall switch 164 is composed of a magnet 1641 and a hall element 1642, the magnet 1641 is disposed on the sand-adding cover 120, and the hall element 1642 is correspondingly disposed on the upper cover 112; first ir sensor switch 165 includes a first ir transmitter 1651 and a first ir receiver 1652, lens 135 disposed around first ir transmitter 1651 for protecting first ir transmitter 1651, and lens 134 disposed around first ir receiver 1652 for protecting first ir receiver 1652; the second infrared inductive switch 166 is composed of a second infrared emitter 1661 and a second infrared receiver 1662, the second infrared emitter 1661 and the second infrared receiver 1662 are oppositely arranged on the lower shell 111 and located at the entrance 113, and infrared rays emitted by the second infrared emitter 1661 are received by the second infrared receiver 1662 after passing through a space enclosed by the entrance 113; the first camera 161 is disposed on the upper cover 112 and located at a position close to the access 113, and when the sand silo 130 is at the initial position, the first camera 161 is not shielded by the sand silo 130, so as to photograph the internal condition of the sand silo 130 through the opening 137. The first weight sensors 162 are provided in four numbers and are uniformly disposed at the bottom of the pet litter box 100 to support the entire pet litter box 100, resulting in the weight of the pet litter box 100. When the pet enters the litter bin 130, the first weight sensor 162 measures the weight of the pet and the pet litter box 100. The hall switch 164 is used to detect whether the sand adding cover 120 is opened, specifically, the scheme that the hall switch 164 detects whether the sand adding cover 120 is opened is to obtain a signal whether the hall element 1642 arranged on the upper cover 112 is triggered (generates a hall effect) by the magnet 1641 arranged on the sand adding cover 120, and if not, give a signal that the sand adding cover 120 is opened. The first infrared induction switch 165 is used for detecting whether a pet exists in the sand silo 130; the second infrared sensing switch 166 is used for detecting whether a pet is present at the entrance 113 of the sand silo 130.
As shown in fig. 4 and 5, control circuit 150, first ir-responsive switch 165 and second ir-responsive switch 166 are disposed in lower housing 111, first ir transmitter 1651 and first ir receiver 1652 are separately and oppositely disposed adjacent to central aperture 132 and central aperture 133, and infrared radiation emitted from first ir transmitter 1651 passes through lens 135, passes through central aperture 132 and the interior of sand silo 130 to central aperture 133, passes through lens 134, and is received by first ir receiver 1652. At this time, if the first infrared receiver 1652 can receive the infrared signal, it indicates that no pet exists in the sand silo 130; otherwise, the pet is present. Similarly, the principle of the second ir-sensitive switch 166 detecting the presence of the pet is the same as that of the first ir-sensitive switch 165, i.e. if the light signal is blocked, the second ir receiver 1662 does not receive the infrared ray, indicating that the pet is present at the entrance 113. The control circuit 150 comprises a microprocessor 151, a memory 152 and a data transmitting and receiving device 153, the detection device 160 is electrically connected with the control circuit 150 to provide a signal for the presence or absence of the pet for the microprocessor 151, and the data transmitting and receiving device 153 is suitable for being in communication connection with an external terminal device or a server to transmit relevant data. The data sending and receiving device 153 may select a commonly used bluetooth chip, WIFI chip or/and SIM card mobile communication chip. In this embodiment, the first camera 161 includes an electrically connected serial port 1611, the electrically connected serial port 1611 is electrically connected to the control circuit 150, and the first camera 161 is configured to acquire a picture or a video in the sand silo 130, and then identify the acquired picture or video, thereby determining whether a pet exists in the sand silo 130. Specifically, the scheme for identifying the acquired picture or video is to compare the existing changes of the picture or video taken before and after the acquired picture or video, or compare the taken picture or video with a reference picture to obtain the existing changes, and if the change parameters meet the set parameters (such as the image when the pet exists), a signal operation that the pet exists is given. In other embodiments, the scheme of identifying the acquired pictures or videos may also be completed by the control circuit 150, in which case the first camera 161 is only used for acquiring the pictures or videos in the sand silo 130, and then transmitting the acquired pictures or videos to the control circuit 150. In addition, the first camera 161 is also disposed at the position of the doorway 113, and is used for acquiring pictures or videos at the doorway 113, so as to identify and judge whether a pet is present at the doorway 113, and if so, a signal indicating the presence of the pet is given.
In this embodiment, the microprocessor 151 is adapted to load program code stored in the memory 152 to perform the following operations: a. receiving a signal whether the sand silo 130 rotates (including starting to rotate or rotating), and if so, executing the following operations; b. detecting whether pets exist in the sand silo 130, detecting whether pets exist at the inlet 113, detecting whether the upper cover 112 and the lower shell 111 are separated, and detecting whether the sand adding cover 120 is opened, wherein if one of the pets exists or is separated or opened, a command that the sand silo 130 stops rotating or rotates by a preset angle or rotates to an initial position is output; c. detecting whether the pet leaves (including leaving the sand silo 130 and leaving the entrance 113), if detecting that the pet leaves, controlling the sand silo 130 to continue rotating after a set time (which is a buffering time, such as 3 seconds); or detecting whether the sand adding cover 120 is closed, if closing is detected, controlling the sand silo 130 to continue rotating after a set time (buffer time, such as 3 seconds) to complete related operations, and if not closing the sand adding cover 120 within a preset time (longer time, such as 30 minutes) is detected, controlling the sand silo 130 to return to an initial position; or detecting whether the upper cover 112 covers the lower shell 111, if so, controlling the sand silo 130 to continue rotating after a set time (for example, 3 seconds) and if not, controlling the sand silo 130 to return to the initial position. The preset angle range of the revolution in operation b is preferably 5 to 10 degrees. An operation of alerting the user may be further included after the operation b, that is, when the presence or the opening is detected, the user is alerted.
In other embodiments, as shown in FIG. 12, the first IR-sensitive switch 165 could be modified to include an IR temperature sensing element 167. At this time, the infrared temperature measuring element 167 is used for acquiring the temperature data in the sand silo 130 through the central hole 132, and if the temperature data reaches the set temperature or the temperature difference between the front and the back reaches the preset value, a signal that the pet exists is given. In this case, no lens may be provided in the center hole 132 and the center hole 133. In other schemes, the infrared temperature measuring element 167 can also be arranged at the position of the first camera 161.
In other embodiments, as shown in fig. 13, when first ir sensing switch 165 is not provided, first camera 161 may be disposed at a position where first ir sensing switch 165 is provided, for example, at a position where first ir emitter 1651. The first camera 161 is used for acquiring pictures or videos in the sand silo 130 through the central hole 132, and then recognizing the acquired pictures or videos, so as to determine whether pets exist in the sand silo 130. At this time, the lenses 134 and 135 may be separately disposed within the central holes 132 and 133 to close off the central holes 132 and 133 and prevent dust in the sand silo 130 from drifting out of the sand silo 130. In addition, when no lens 134 or 135 is provided in the center hole 132 or the center hole 133, the first infrared transmitter 1651 and the first infrared receiver 1652 are also provided separately and oppositely in the center hole 132 or the center hole 133.
In other embodiments, the first weight sensor 162 may also be disposed at the roller 1111, becoming the second weight sensor. At this time, as shown in fig. 10, a roller 1111 is further protruded from a connection space of the casing 110 and the sand silo 130. Since the roller 1111 protrudes from the gap between the housing 110 and the sand silo 130, the sand silo 130 is in contact with the roller 1111 after the sand silo 130 is disposed in the housing 110. The second weight sensor is used to obtain the weight information of the sand silo 130, and if the weight information obtained by the second weight sensor reaches the set value or the change before and after the weight information reaches the set value, the second weight sensor gives a signal.
In other embodiments, the first weight sensor 162 may be disposed at the doorway 113 and may be changed to a third weight sensor for acquiring weight information of the doorway, and when the acquired weight information reaches a set value or a change before and after the acquired weight information reaches a set value, a signal indicating the presence of a pet is given. In this case, the bottom surface of the doorway 113 is preferably formed of a flexible structure, a heavy deformable structure, or a movable member.
In other embodiments, the hall switch 164 may be changed to a contact switch (e.g., a metal dome switch, a switch composed of a magnet and a reed switch, a switch loop composed of two pogo pins and a conductor, or a tact switch), which is disposed on the housing 110 and located right below the sand-adding cover 120, and is used to detect whether a line is connected, and if so, it indicates that the sand-adding cover 120 touches the contact switch; if not, the sand adding cover 120 is opened, and a signal for opening the sand adding cover 120 is given. Such as: when the metal dome switch is touched and switched on by the sand adding cover 120, the sand adding cover 120 is considered to be not opened, otherwise, the sand adding cover is considered to be opened. If the sand adding cover 120 is not provided, the user can also add pet sand into the sand silo 130 after the upper cover 112 is separated from the lower case 111, and thus the upper cover 112 also corresponds to the sand adding cover. At this time, the hall switch 164 or the contact switch is used to detect whether the upper cover 112 and the lower cover 111 are separated. Similarly, the detection of whether the sand adding cover 120 is opened and whether the upper cover 112 and the lower cover 111 are separated can also be realized by two sets of detection devices (including two sets of contact switches or two sets of hall switches 164).
In other embodiments, the infrared temperature measuring element 167 may also be disposed at the entrance 113 to obtain the temperature data at the entrance 113, and signal the presence of the pet if the temperature data reaches the set temperature or the temperature difference between the front and the back reaches the predetermined value.
In other embodiments, the first ir transmitter 1651 or the first ir receiver 1652 may be modified to be a pyroelectric sensor, which is used to obtain whether there is a fluctuating ir radiation signal in the sand silo 130, and if so, the presence of a pet in the sand silo 130 is determined to give a signal that a pet is present. Specifically, when the pet moves in the sand silo 130, the pyroelectric sensor may obtain a sudden pulse signal according to the change of the external infrared signal, and if the pet does not exist or does not move, the sudden pulse signal does not exist. However, when the sand silo 130 rotates, the pet is bound to move. Similarly, the pyroelectric sensor may also be disposed at the position of the doorway 113 for determining whether a pet is present at the doorway 113.
In other embodiments, first camera 161 or first infrared transmitter 1651 or first infrared receiver 1652 may be modified to be a distance measuring sensor for measuring the size of the space inside sand silo 130, and if the measured size is smaller than a predetermined value, it is determined that a pet is present in sand silo 130, and a signal indicating the presence of a pet is given. Similarly, the distance measuring sensor can also be used to determine whether a pet is present at the doorway 113. If the size of the space enclosed by the doorway 113 is measured, and if the measured size is smaller than a set value, it is determined that a pet is present in the doorway 113, and a signal indicating the presence of a pet is given.
As shown in fig. 14, which shows a flow of a working method of the pet litter box according to the preferred embodiment, it comprises the following steps:
s101, the microprocessor 151 receives a signal indicating whether the sand silo 130 rotates, and if the signal indicates that the sand silo 130 rotates, the following steps are executed. Since the sand silo 130 is generally rotated when the excrement is cleared, a signal indicating whether the sand silo 130 is rotated or not may be actively given by a user or automatically given by the pet litter box 100 according to the amount of the excrement in the sand silo 130. If the amount of excrement in the sand silo 130 is larger than a certain value (such as weight), a signal for rotating the sand silo 130 is automatically given to clear the excrement.
S102, the detecting device 160 detects whether there is a pet in the sand silo 130, detects whether there is a pet at the inlet 113, detects whether the upper cover 112 and the lower cover 111 are separated, and detects whether the sand adding cover 120 is opened. The specific detection scheme of the detection device 160 at least comprises the following modes:
the weight information of the pet litter box 100 is acquired by the first weight sensor 162, and if the acquired weight information reaches a set value or changes before and after the weight information reaches a set value, a signal indicating the presence of a pet is given.
By detecting whether the dome switch 1151 is pressed to be turned on by the upper cover 112, if the dome switch 1151 is pressed to be turned on, the upper cover 112 is considered to be covered on the lower shell 111, otherwise, the separation is considered to give a separation signal.
The hall switch 164 is used to obtain whether the hall element 1642 arranged on the upper cover 112 is triggered by the magnet 1641 arranged on the sanding cover 120 (generating a hall effect), and if not, the sanding cover 120 is opened, otherwise, the sanding cover is not opened.
Whether a pet exists in the sand silo 130 is detected through the first infrared induction switch 165; infrared radiation from first infrared emitter 1651 passes through lens 135, through central aperture 132 and the interior of sand silo 130 to central aperture 133, through lens 134, and is received by first infrared receiver 1652. At this time, if the first infrared receiver 1652 receives the infrared signal, it indicates that no pet exists in the sand silo 130; otherwise, the pet is present.
The presence of a pet at the entrance 113 is detected by the second ir-sensitive switch 166, which has the same detection principle as the first ir-sensitive switch 165, i.e. if the light signal is blocked, the second ir receiver 1662 does not receive infrared rays, indicating that a pet is present at the entrance 113.
The first camera 161 is used to acquire pictures or videos in the sand silo 130 or at the doorway 113, and then the acquired pictures or videos are identified to determine whether a pet is present. If the pictures or videos shot before and after exist changes, or the shot pictures or videos are compared with the reference pictures to obtain the existing changes, and the change parameters meet the set parameters, a signal that the pet exists is given.
The temperature data in the sand silo 130 or at the inlet 113 is obtained through the infrared temperature measuring element 167, and if the temperature data reaches the set temperature or the temperature difference between the front and the back reaches the preset value, the existing signal is given.
The pyroelectric sensor detects whether there is a fluctuating infrared radiation signal in the sand silo 130 or at the doorway 113, and if so, it gives a signal that there is a pet.
The size of the entrance 113 is detected by a distance measuring sensor, and if the detected size is smaller than a set value, it gives a signal that a pet is present.
S103, if there is a pet, the upper cover 112 is separated from the lower shell 111, or the sand adding cover 120 is opened, the microprocessor 151 outputs a command that the sand silo 130 stops rotating or rotates a preset angle or rotates to an initial position. Wherein the predetermined angle range of the rotation is preferably 5 to 10 degrees, and the initial position is a position where the opening 137 faces the inlet 113 and the sanding cover 120.
And S104, sending an alarm to the user to remind the user to confirm the safety condition of the pet. The scheme of giving an alarm to the user is preferably to give an alarm by controlling an alarm device; or information pushing can be carried out on terminal equipment (such as a mobile phone, a bracelet and the like) appointed by a user, so that the user can confirm whether the pet is safe or not in time.
S105, detecting whether the pet in the sand silo 130 and at the entrance 113 leaves. The scheme for detecting whether to leave is the same as the scheme for detecting the presence of the pet, and if the pet does not exist, the pet leaves, please refer to the description of the related paragraphs, which is not repeated herein for brevity.
S106, detecting whether the sand adding cover 120 is closed or not and detecting whether the upper cover 112 and the lower cover 111 are closed or not. Specifically, a signal indicating whether the hall element 1642 is triggered (hall effect is generated) by the magnet 1641 is obtained, and if the hall element is triggered, a signal indicating that the sand adding cover 120 is closed is given; and acquiring a signal whether the metal dome switch 1151 is pressed by the upper cover 112 to be connected, and if the metal dome switch 1151 is connected, giving a signal that the upper cover 112 and the lower cover 111 are closed.
S107, if it is detected that the pet leaves the sand silo 130 and the access 113, and it is detected that the sand adding cover 120 is closed and the upper cover 112 and the lower shell 111 are closed, controlling the sand silo 130 to continue rotating after a set time (such as 3 seconds) so as to execute the original rotating work and complete the related operation; if it is detected that the sand adding cover 120 is not closed for a predetermined time (for a long time, for example, 30 minutes), or the upper cover 112 is not covered on the lower casing 111 for a predetermined time (for a long time, for example, 30 minutes), the sand silo 130 is controlled to be restored to the original position.
The steps S105 and S106 are performed to ensure that the pet leaves the dangerous area of the pet litter box 100 during the rotation of the sand silo 130, so as to ensure the safety of the pet.
Because the pet toilet 100 can be actively judged whether a pet exists in the pet toilet or before the rotation of the sand bin 130, and the safety protection action can be actively started when the pet exists, the pet can be prevented from being injured by being clamped in the rotation process of the sand bin 130, and the injury to the pet can be avoided.
