Referring to fig. 1 and 2, a device for removing pet excrement according to a preferred embodiment of the present invention is disclosed. The device comprises a base 11 and an operating shell 10 pivotally supported on the base, wherein the operating shell 10 is provided with an opening. The operation housing 10 includes an operation plane 30 and a screen comb plane 20, wherein the operation plane 30 has an area smaller than the screen comb plane 20, and the screen comb plane 20 has a plurality of screen comb slots 21. The operation housing 10 is rotatable about a rotation axis which is a horizontal line passing through the operation housing 10 from the center of the left side of the base 11 to the center of the right side of the base 11. The axis of rotation may be defined as the virtual line perpendicular to the vertical plane and direction of movement of the animal when entering and leaving the operating housing 10 through the operating housing opening 14. The rotation is bidirectional and can be operated manually or automatically. In this preferred embodiment of the invention, the rotation and the corresponding change of orientation of the operating housing 10 is automatically driven by the electric motor 17. A gear track 15 on the operating housing 10 cooperates with a motor gear 16 fixed to the output shaft of a motor 17. The motor gear 16 is located in the same vertical plane as the gear track 15 on the left side of the base 11. The system controls the motor 17 and communicates with the motor 17 to determine the angle of rotation and the corresponding orientation of the operating housing 10.
Also embedded within base 11 are one or more hall effect sensors attached. Inside the operation housing, one or more magnetic substances, which may be permanent magnets, are also provided. The hall effect sensor and the permanent magnet are combined to form a position sensor unit for sensing the position of the operating housing 10 relative to the base 11 and providing one or more position signals to the system. The hall effect sensor detects the position of the permanent magnet to determine the degree of rotation of the operating case 10, so that the rotation angle of the operating case 10 can be accurately determined and controlled.
In a preferred embodiment, the handle housing opening 14 serves as an entrance and exit for the pet when the handle housing 10 is in the handle position. When the operating housing 10 is rotated to the cleaning position at a predetermined angle, the operating housing opening 14 may serve as a waste opening for dumping pet excrement, thereby allowing the pet excrement to be discharged therefrom by gravity. When the operation housing is rotated to the cleaning position from the operation position, the rotation angle is slightly larger than or equal to a half of the circumferential angle. The magnetic substance arranged inside the operation housing is arranged according to the requirements of defining the operation position and the cleaning position. In detail, a first magnetic material is disposed at an operation positioning position on the side of the operation housing for calibrating the operation position, and a second magnetic material is disposed at a cleaning positioning position on the side of the operation housing for calibrating the cleaning position, wherein the polarities of the first magnetic material and the second magnetic material are opposite.
As shown in fig. 1 and 2. The screen comb plate 20 includes one or more screen comb slots 21, each screen comb slot 21 having a plurality of screen openings 23 therein and one or more non-open portions 22 having no openings therein.
The screen comb plate 20 is generally flat and may be made of plastic, metal or any other suitable material. The non-open portion 22 of the screen comb plate 20 is glued or otherwise attached to the inner longitudinal wall of the operating housing 10 adjacent to the operating housing opening 14. The screen comb plane 20 itself cannot move but rotates together with the operating case 10 and rotates in the same manner as the operating case 10. The non-opening portion 22 and the inner longitudinal wall of the operating housing 10 together form a trough so that cleaning particles can pass through the screen portion 21 of the comb plate 20, enter the trough and be retained within the trough 52 when performing a cleaning operation. Pet waste of larger size cannot pass through the screen portion 21 of the comb plate 20. Accordingly, the pet excrement is retained by the mesh portion 21 and is discharged outside the trough. In other words, in the operating position, the pet excrement entering the operating shell falls on the cleaning particles laid on the operating plane, the pet excrement and the cleaning particles are both located on the first side relative to the screen comb plane, and when the operating shell rotates to the cleaning position, the cleaning particles pass through the screen comb slot to enter the second side, and the pet excrement is left on the first side and is discharged from the opening by gravity. This operation will be described in detail below.
As shown in fig. 2, each screen opening 23 in the screen portion 21 is sized to allow the cleaning particles 50 to pass through and prevent pet waste having a much larger size from passing through. In certain embodiments, the mesh 23 has a width of about 8 mm. The cleaning particles passing through the mesh 23 are uncontaminated waste material which is substantially uncontaminated by pet waste. The cleaning particles are retained within the trough for later use when dumping pet waste and can be reused when the operating housing 10 is rotated back to the operating position.
During the cleaning operation, it can be seen that the dunnage collection device 01 operates as follows, and as shown in fig. 3. The operating position of the operating housing 10 is shown in fig. 2. A desired amount of cleaning particles can be placed in the handle housing 10. The pet enters the operating housing 10 through the operating housing opening 14 and deposits pet excrement into the cleaning particles in the operating position, and at a subsequent time when the device starts a cleaning operation, the operating housing 10 is rotated by a certain angle from the standby position, as shown in fig. 3, and the operating housing 10 is moved to the cleaning position. Clockwise as in figure 3. The angle may be in the range of 120 ° to 185 ° in the counter clockwise direction, and is preferably 185 ° in the clockwise direction. During rotation, the cleaning particles slide along the inner surface of the operating housing 10 under the influence of gravity, pass through the screen portion 21 and enter the groove 52. I.e. from the first side to the second side.
At the same time, pet waste having a much larger size is too large to be screened, such that pet waste will remain on the first side, continue to slide through the screen, and be caught by the screen comb surface 20 out of the channel 52. When the operating housing opening 14 is rotated to a position above the receptacle 35, the pet excrement will then fall under the influence of gravity through the operating housing opening 14 to the receptacle 35. Thereby, the animal waste 51 is separated from the cleaning particles by the sieve comb plane 20. As can be seen in fig. 1 and 2 and fig. 3. The cleaning particles are captured within the tank 52 and can be reused.
After the pet excrement is poured into the container 35, the operation housing 10 is rotated in the opposite direction by a certain angle (clockwise as shown in fig. 4) to return to the original operation position angle. The angle may be 95 deg. in a counter clockwise direction, preferably in a clockwise direction. By doing so, the cleaning particles are reintroduced such that they pass through the screen portion 21 a second time and exit the slots during the clockwise rotation. Thus, when the operating housing 10 is rotated to operation, the tank is emptied, as shown in fig. 4. It will be appreciated that the cleaning particles do not fall from a significant height to the bottom of the operation housing 10, but slide smoothly along the inner surface of the operation housing 10. Alternatively, if the operating housing 10 is rotated counterclockwise to the third position, the cleaning particles will first be temporarily trapped in the trough, as it cannot pass through the walls of the non-opening portion 22, and then fall from a greater height into the trough. When the partition 20 is rotated to the top before the operation housing 10 reaches the third position, the bottom of the operation housing is rotated. After reintroduction of the cleaning particles, this will enable the animal to enter the operating housing 10 again at the first location via the operating housing opening 14 to deposit pet excrement again.
In order to reduce the net friction and the dynamic friction generated when the operation housing 10 rotates, at least one roller is disposed on the base to support the operation housing 10 to avoid the downward pressure generated when the operation housing directly contacts the base in a large area, so as to reduce the friction generated when the operation housing rotates. In a preferred embodiment, four corners of the base, which are quadrangular with each other, are provided with rollers, respectively, so that the operation housing 10 can be smoothly rotated using four fulcrums. However, in an alternative preferred embodiment, the above-described design for reducing the dynamic friction and the static friction may be implemented using three rollers, as long as the center of gravity of the operation housing 10 is calculated to be centered. Furthermore, in order to further reduce the friction force generated on the side surface of the operation housing 10 during rotation, the side surface of the operation housing has a protruding pressure reducing ring on the circumference thereof for reducing the friction force generated by the rotation of the operation housing. The protruded decompression ring may be provided only on one side having the driving gear, or may be provided on both sides of the side circumference of the operation case.
In addition, pet waste may include various aspects, some of which have a chance of adhering to the operative surface. In order to solve the problem that pet excrement adheres to the operation plane, after the operation platform enters the fixed cleaning position of the cleaning operation, the operation platform rotates around the cleaning position by a first preset angle in a short distance, and the sticky pet excrement is shaken off by torque generated. That is, after the operating housing is rotated to the cleaning position and before the operating housing is rotated in the reverse direction of the pivot to return to the operating position, the operating housing is rotated back and forth along the pivot within a first predetermined angle with the cleaning position as the origin to increase the cleaning effect.
Furthermore, when the system resets to the operating position by clean position, based on the effect of resistance and the gravity that produces between the clean granule, probably make clean granule not pave on the operating plane, will operate the casing and increase syntropy rotation time interval according to the direction of rotation that returns to the operating position this moment, or an angle to the moment of application that can utilize this moment makes clean granule pave on the operating plane, promptly when operating the casing along the pivot rotate in order to return to behind the operating position, syntropy rotate one and predetermine the angle or predetermine the time so that lay in the surface of the clean granule of operating plane is on a parallel with the operating plane
