Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Embodiment 1, as shown in fig. 1-7, the present invention comprises an upper shell 0 and a lower shell 1, wherein the upper shell 0 is embedded with the lower shell 1, i.e. the upper shell 0 can be detached from the lower shell 1 under the action of human force to expose the internal structure between the two shells. The upper housing 0 and the lower housing 1 enclose a ventilated cavity, the driving device of the pet toilet is disposed in the cavity, the driving device includes a first transmission part and a second transmission part, the first transmission part 31 and the second transmission part 32 are connected without a gap, the tail end of the first transmission part 31 and the head end of the second transmission part 32 are driven by the same set of motors 33/34/35, of course, the first transmission part 31 and the second transmission part 32 can share the same transmission track, and it is important that the track type transmission part is provided with a baffle 36 with a grid, and the included angle between the first transmission part 31 and the second transmission part 32 is less than 180 degrees and more than 90 degrees.
The motor 33/34/35 is controlled by a PLC control board, more than 1, for example more than 2 sensors are connected with the control board, the sensors comprise a first sensor and a second sensor, when the first sensor senses that a cat enters the cat toilet, the second sensor senses that a cat leaves the cat toilet, the control board obtains the interval between the cat entering the cat toilet and the cat leaving the cat toilet, and then whether the motor is controlled to drive the conveying part to rotate to clean excrement is judged. The sensor can be an infrared sensor or a temperature control sensor. The time for controlling the movement of the excrement cleaning mechanism 3 to clean excrement is uncertain, and only after the cat goes to the cat toilet and excretes the excrement, and the time in the cat toilet is not less than the set time, the control module can control the excrement cleaning mechanism 3 to perform excrement 5 cleaning work, so that the excrement cleaning mechanism 3 is prevented from doing useless work, and the electric energy is greatly saved. Compared with the automatic pet excrement cleaning mechanism in the prior art, the automatic pet excrement cleaning mechanism is greatly simplified in structure and easier to demould.
And in the prior art through letting excrement and urine shovel remove in the cat litter, realize the design of excrement and urine clearance, there is following fatal defect:
the design of a common excrement shovel is in a comb tooth shape, the excrement shovel with the comb tooth shape is controlled by a motor to move from one end of a cat litter pool to the bottom and the other end of the cat litter pool to clean cat excrement 5, but the excrement just pulled by a cat is soft under the common condition, if a cat digs a squatting pit deeper when the cat is convenient, the cat excrement can be stuck on a base of a cat toilet, the excrement just pulled by the cat can be broken by the force of the comb tooth-shaped excrement shovel, the cat excrement cleaning failure can be caused, and when the cat is sick, the cat excrement is not solid, the cat excrement can be stained on the excrement shovel, and the cat excrement is very unhygienic; the above technical problem is not solved by the present invention, and cat litter slides down the sloping second conveyor section, and cat litter is cleared from the second conveyor section into the litter box 4 along with the conveyor belt by the baffle 36.
Specifically, as shown in fig. 5 to 7, the first conveying part 31 is parallel to the horizontal plane, the angle between the second conveying part 32 and the first conveying part 31 is 130 degrees to 150 degrees, and the optimum angle is 135 degrees in consideration of the difference between the friction factor and the dynamic friction factor between cat waste and cat litter, at the time of the gradient, cat litter passes through the first conveying part to the second conveying part 32, since cat litter is mostly round and granular, when the cat litter reaches the second conveying part 32 having the gradient, the cat litter leaks out of the baffle 36 having a free mesh and slides again onto the first conveying part 31, and cat litter does not leak from the mesh of the baffle 36 to the first conveying part 31 because cat litter is irregular and has a volume much larger than that of cat litter and much larger than the size of the mesh on the baffle 36, but moves to the second conveying part 32 held by the movement of the second conveying part 32, through the faeces inlet portion into the faeces cleaning cassette 4.
In embodiment 2, the included angle between the first conveying part 31 and the second conveying part 32 is preferably 130 degrees and 135 degrees, and preferably 135 degrees, when 135 degrees, the cat litter can slide off the second conveying part 32 most easily and the cat litter can not fall off the baffle 36 because the second conveying part 32 is too steep, which affects the cleaning effect. Because the baffle 36 is made of a material with certain hardness, the weight of the common cat excrement can be completely withstood without great deformation, such as PV plastic and the like. And the height of the baffle 36 should not be too high because the cat will cover the cat's faeces with the paw after the cat has got to do so, and if the height of the baffle 36 is too high, the cat's paw will catch on the baffle 36, and the life of the cat toilet will be affected by the damage to the conveyor track and the baffle.
The angle between the apron 36 and the conveyor track is also defined, typically the angle between the apron 36 and the track conveyor (conveyor track) is 70-90 degrees, which is the angle between the direction of travel of the track conveyor and the apron 36.
Preferably, the degree of the included angle is 85 degrees. As shown in fig. 5-7, after many tests, the included angle between the first conveying part 31 and the second conveying part 32 is matched during the degree, so that the cleaning effect is the best, cat feces are most likely to fall off from the baffle, the cat feces can successfully fall off from the conveying track into the feces cleaning box 4, and the cleaning is more thorough under the gravity of the cat feces.
According to the research, cats usually leave the toilet for about 3 minutes (with a digging pit and excrement buried), but some cats take a little longer time, but the time for leaving the toilet for cats cannot be lower than 30 seconds in general, and cats lower than 30 seconds are hidden. Therefore, the cat toilet is also provided with the sensor, so long as the time for the cat to go to the toilet is detected to reach a certain time, and after the cat leaves the cat toilet for a plurality of seconds, for example, 40 seconds, the control system controls the motor to drive the conveying crawler to rotate, so that the aim of cleaning is fulfilled. The reason why the zero clearing is carried out after the cat pauses for about 40 seconds is that the curiosity of the cat is too strong, and if the excrement cleaning mechanism 3 operates as soon as the cat leaves the cat toilet, the cat may re-drill the cat toilet due to the strong curiosity, so that the excrement cleaning work is interrupted, and the cleaning efficiency is influenced. Typically, when cleaning, if the sensor detects that the cat has re-entered the cat toilet, the faecal cleaning work is immediately stopped to prevent injury to the cat.
Embodiment 4, as shown in fig. 3 to 4, a stool-cleaning box 4 is provided under the second transfer part, and the stool-cleaning box 4 is detachably connected to a slide rail 41 provided at the bottom of the lower case 1 by a push-pull plate 42. The user waits that excrement and urine has filled excrement and urine clearance box 4 can pull out the clearance of excrement and urine clearance box 4 from the cat lavatory. Preferably, the second conveying part 32 is supported by 2 telescopic brackets 37, and strip-shaped activated carbon is arranged between 2 telescopic brackets 37. Can absorb the peculiar smell of the cat excrement. Not only can be the bar active carbon, but also can be other air fresheners that can adsorb the peculiar smell.
The casing include last shell 0 and with go up shell 1 and agree with shell 1 down, the top of going up shell 0 is equipped with bleeder vent 02, the front portion is close first transfer portion 31 department and is equipped with business turn over door 01, is close excrement and urine cleaning box 4 department is equipped with rubbish clearance door 03.
When the cat toilet needs to be thoroughly cleaned or the cat litter box (on the first conveying part 31) needs to be protected from new cat litter, the upper shell 0 can be taken down from the lower shell 1, so that the operation of a user is facilitated.
In example 5, the mesh or comb teeth of the baffle 36 have a larger mesh diameter than the cat litter 6. The diameter of the mesh on the baffle 36 is generally 1.5 times larger than that of the cat litter, and at this time, the cat litter 6 is more easily leaked from the mesh 36 and is smoothly leaked.
The invention has simple structure, convenient operation and easy popularization and use.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
