Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a multifunctional automatic cat toilet. Background Technology

[0002] Cat litter boxes are used for cats to excrete waste. After a cat urinates, the waste needs to be promptly separated from the litter box, bagged, and disposed of in a trash can. Failure to do so can result in strong, unpleasant odors, infestations of parasites, and other problems, severely impacting the living environment and pet-owning experience for cat owners.

[0003] Automatic cat litter boxes on the market only solve the problem of separating cat excrement from litter, requiring frequent manual addition of litter and disposal of cat feces.

[0004] Most automatic cat litter boxes currently on the market are roller-type designs. These rely on a rotating roller and a filter to separate cat litter from feces. However, if a cat has diarrhea, urinates on the bottom or edges of the roller, or other issues, the feces can become stuck and cannot be separated by the roller's rotation. Roller-type litter boxes also commonly suffer from leakage, requiring periodic cleaning of the internal components.

[0005] Furthermore, current automatic cat litter boxes lack features such as litter washing, spinning, drying, and reuse. Washable cat litter can be reused, completely freeing up cat owners' time, eliminating the need for frequent litter scooping, adding litter, and disposing of feces. This reduces the cost of cat ownership and decreases the generation of urban waste such as cat excrement and contaminated litter.

[0006] With the increasing number of single cat owners and travelers, cat waste left unattended for extended periods can cause unpleasant odors and insect infestations if not promptly disposed of. This severely impacts cat owners' travel and leisure activities.

[0007] Carrying dozens of kilograms of cat litter home from the station and throwing cat excrement into the trash can requires a lot of physical strength, especially for girls.

[0008] Furthermore, pet drying boxes are used infrequently and take up space. Current cat litter boxes do not have a hair drying or blow-drying function, so cats need to have their fur dried or blow-dried after bathing. Utility Model Content

Detailed Implementation

[0074] The present invention will now be described in further detail with reference to the accompanying drawings.

[0075] refer to Figures 1 to 3 , Figures 6 to 8 A multi-functional cat litter box, comprising:

[0076] The outer casing 1 includes a main body 11 and a front door 12. The main body 11 has an inner compartment 10, and the front door 12 is provided on the side wall of the main body 11. The front door 12 has an inlet and outlet 121. The main body 11 can be cylindrical or columnar. The side wall of the main body 11 has a first opening 111. The front door 12 is rotatably assembled to the first opening 111 by means of a hinge or pivot, so that it can be opened and closed. The front door 12 is provided to facilitate the replacement and placement of components such as the litter box assembly 4, the hair drying assembly 6, and the guide plate 53. The inlet and outlet 121 is used for the cat to enter and exit.

[0077] The chassis assembly 3 is located at the bottom of the inner compartment 10 of the main body 11, and the chassis assembly 3 is lower than the front compartment door 12. The chassis assembly 3 includes an inner bucket 30, a crushing chamber 31, a crushing mechanism 32, and a drain pipe assembly 34. The crushing chamber 31 is located at the edge of the inner bucket 30 and is lower than the bottom wall of the inner bucket 30. The crushing chamber 31 is connected to the inner bucket 30. The crushing chamber 31 is equipped with a crushing mechanism 32, which can crush cat feces. The crushing chamber 31 is connected to the drain pipe assembly 34.

[0078] The litter tray assembly 4 is used to hold cat litter; the litter tray assembly 4 is located on top of or inside the inner bucket 30, and the litter tray assembly 4 can rotate horizontally.

[0079] The electric scoop assembly 7 includes a scoop 71 that can scoop cat feces from the litter box and transport the cat feces to the shredding chamber 31;

[0080] as well as

[0081] The water inlet assembly 8 can add water to the crushing chamber 31 and the inner tub 30, and can also spray water to clean the entire inner chamber.

[0082] Thus, the cat enters the litter box assembly 4 through inlet / outlet 121 and defecates. When the amount of cat feces reaches a certain level, the electric inner door assembly 2 rotates to close inlet / outlet 121, causing the litter box assembly 4 to rotate back and forth. This causes relative movement between the litter box assembly 4 and the scoop 71 of the electric scoop assembly 7, resulting in the cat feces being collected on the scoop 71. The scoop 71 then scoops up the cat feces, separating it from the litter and conveying it to the grinding chamber 31. Water is then added to the grinding chamber 31 by the water inlet assembly 8, and the grinding mechanism 32 breaks the cat feces into small particles. After grinding, the cat feces are discharged with the water to the drain pipe assembly 34, which connects to the sewer, thus achieving the cleaning of the cat feces. Alternatively, the grinding mechanism 32 can break the cat feces into small particles before adding water.

[0083] Water is added to the crushing chamber 31 by the water inlet assembly 8, and the water is added to the inner tank 30. The water in the inner tank 30 enters the litter box 42 through the first perforated part 421. The second motor 33 drives the litter box 42 to rotate back and forth. The water stirring plate 422 at the bottom of the litter box 42 agitates the water in the inner tank 30 to clean the litter in the litter box 42. After the litter is cleaned, the dirty water is drained away through the drain pipe assembly 34 connected to the sewer. The second motor 33 drives the litter box 42 to rotate at high speed, and at the same time, the air intake fan 51 blows hot air through the heating wire 511 and through the guide plate 53 to the litter in the litter box 42, thereby quickly drying the litter.

[0084] refer to Figures 9 to 11 The electric shovel assembly 7 includes a third motor 72; the third motor 72 can be fixed to the inner wall of the main body 11.

[0085] The shovel 71 includes a collection port 711 and a conveying channel 712. The end of the conveying channel 712 away from the collection port 711 is connected to the third motor 72. The end of the conveying channel 712 away from the collection port 711 corresponds to the crushing chamber 31. The collection port 711 is used to collect cat feces, and the conveying channel 712 is used to guide the cat feces to the crushing chamber 31.

[0086] Both the collection port 711 and the conveying channel 712 have a second perforated part 710 on their walls; the perforated part can be a strip-shaped or circular through hole, which allows cat litter to flow away while retaining cat feces;

[0087] The third motor 72 can drive the shovel 71 to switch between horizontal and vertical states; this can be understood as the shovel 71 being able to rotate within a range of about 90 degrees, thereby realizing the shoveling action.

[0088] When the scoop 71 is in a horizontal position, the collection port 711 enters the interior of the litter box assembly 4. At this time, the collection port 711 is close to or slightly abutting the bottom wall of the litter box assembly 4. The litter box assembly 4 and the scoop 71 move relative to each other, causing cat feces to enter the collection port 711 with the movement. Then, the scoop 71 switches to a vertical position, that is, it rotates upward about 90 degrees to scoop up the cat feces and transport it to the grinding chamber 31.

[0089] The scoop 71 is positioned above the litter tray assembly 4. When not scooping, the scoop 71 is in a vertical position, thus not obstructing the cat's normal activities. When the scoop 71 is in a vertical position, the conveyor 712 is positioned above the litter bin 31, thereby enabling the delivery of cat feces to the litter bin 31.

[0090] refer to Figure 11 When the scoop 71 is in a horizontal position, the first position 711a of the collection port 711 corresponds to the center of the litter box assembly 4, and the second position 711b of the collection port 711 corresponds to the edge of the litter box assembly 4. The collection port 711 is asymmetrically flared, and the width of the collection port 711 is greater than or equal to the radius of the litter box assembly 4, thereby increasing the quantity and efficiency of collecting cat feces.

[0091] refer to Figure 9 The cat litter tray component 4 can rotate in a single direction or in a reciprocating motion.

[0092] Unidirectional rotation: Rotates towards the collection port 711, that is, rotates along direction A;

[0093] Reciprocating rotation: Alternating rotation in both directions; the rotation towards the collection port 711 is set as the forward rotation (direction A). Rotation cycle: one or several revolutions in the forward direction, followed by one or several revolutions in the reverse direction. For example, setting one revolution in the forward direction followed by one revolution in the reverse direction constitutes one reciprocating rotation cycle; for example, setting two revolutions in the forward direction followed by two revolutions in the reverse direction constitutes one reciprocating rotation cycle; of course, it can also be set such that multiple revolutions in the forward direction and multiple revolutions in the reverse direction constitute one cycle.

[0094] The litter box assembly 4 is connected to the second motor 33, which drives the litter box assembly 4 to rotate in one direction or reciprocate.

[0095] When set to rotate in one direction, the second motor 33 drives the litter box 42 to rotate at high speed, quickly drying the water in the litter.

[0096] When set to reciprocating rotation, the reverse rotation has a certain stirring effect, which loosens the cat feces and allows for the collection of more cat feces or more complete collection of the remaining cat feces when rotating forward again. In this way, the reciprocating rotation can more thoroughly clean and separate cat feces from the litter box, improving the cleaning effect.

[0097] When set to reciprocating rotation, the water inlet component 8 adds water to the crushing chamber 31, and the water is added to the inner tub 30. The water in the inner tub 30 enters the litter box 42 through the first perforated part 421 of the litter box 42. The second motor 33 drives the litter box 42 to rotate reciprocally. The stirring plate 422 at the bottom of the litter box 42 stirs the water in the inner tub 30 to clean the litter in the litter box 42.

[0098] During forward rotation of the litter box assembly 4, such as at or near the end of forward rotation, the scoop 71 of the electric scoop assembly 7 performs a scooping action.

[0099] When the litter box 42 is reciprocating and rotating to wash the litter or rotating in one direction to spin dry the litter, the scoop 71 is in a vertical position, so as not to hinder the washing and spin-drying action of the litter box 42.

[0100] refer to Figure 8 The crushing mechanism 32 includes a crushing blade 321 and a first rotating shaft 322; the upper end of the first rotating shaft 322 is connected to the crushing blade 321, and the lower end is connected to the second motor 33 for driving. The crushing blade 321 can be provided in multiple layers, for example, 3 layers, with multiple blades in each layer.

[0101] refer to Figure 12 and Figure 13A second motor 33 is provided below the inner barrel 30 of the chassis assembly 3. The upper output shaft 331 of the second motor 33 is connected to the litter tray assembly 4. The litter tray assembly 4 is provided with a first shaft hole 40 that mates with the upper output shaft 331. The lower output shaft 332 of the second motor 33 can be connected to the first rotating shaft 322 through the pulley structure 323. In this way, the second motor 33 jointly drives the litter tray assembly 4 and the shredding mechanism 32 to rotate.

[0102] refer to Figure 8 The crushing chamber 31 is equipped with a drain outlet 312, and the drain outlet 312 is equipped with a filter plug 313. The filter plug 313 is used to prevent large cat feces particles from being directly discharged into the drain pipe assembly 34. Only when the cat feces are crushed into small particles can they pass through the filter plug 313 and be discharged into the drain pipe assembly 34.

[0103] refer to Figure 8 The top of the crushing chamber 31 is provided with an overflow port 314; when the water volume or water level in the crushing chamber 31 or the inner tank 30 exceeds the preset value, the water can be discharged from the overflow port 314 to the drain pipe assembly 34.

[0104] refer to Figure 13 The drain outlet 312 and the overflow outlet 314 are respectively connected to the drain pipe assembly 34; the drain pipe assembly 34 includes a first branch pipe 341, a second branch pipe 342 and a main pipe 343. The first branch pipe 341 is connected to the drain outlet 312, the second branch pipe 342 is connected to the overflow outlet 314, and both the first branch pipe 341 and the second branch pipe 342 are connected to the main pipe 343. The first branch pipe 341 is equipped with a drain valve 344, which is connected to a puller 345. The drain valve 344 is opened by pulling the valve through the puller 345. Of course, the drain valve 344 can also be a solenoid valve.

[0105] refer to Figure 8 The chassis assembly 3 also includes a shock-absorbing spring column 35 and a counterweight 36. The shock-absorbing spring column 35 includes a spring and a telescopic column, the upper end of which is slidable. The shock-absorbing spring column 35 is connected to the spring mounting seat 315 of the inner tub 30. The spring is fitted into the telescopic column, the upper end of which is connected to the spring mounting seat 315, the lower end of which is connected to the telescopic column, and the bottom end of which is connected to the supporting surface such as the outer shell 1. The shock-absorbing spring column 35 is used to absorb the vibration and swaying when the chassis assembly 3 rotates, reducing noise and the swaying of the entire automatic cat toilet.

[0106] The counterweight 36 is located on the outside of the inner tub 30. Multiple counterweights can be evenly distributed to increase the weight of the chassis assembly 3 or lower the center of gravity of the chassis assembly 3, reduce the vibration amplitude of the chassis assembly 3, balance the high-speed rotation of the litter box 42, and improve the stability of the chassis assembly 3.

[0107] refer to Figure 4 and Figure 5The water inlet assembly 8 includes a first water outlet 811 and a second water outlet 813;

[0108] The first water outlet 811 corresponds to the crushing chamber 31. For example, the first water outlet 811 is located above the crushing chamber 31, and the first water outlet 811 is equipped with a first solenoid valve 812.

[0109] The second water outlet 813 corresponds to the litter box assembly 4. For example, the second water outlet 813 is located above the center of the litter box assembly 4. The second water outlet 813 is equipped with a second solenoid valve 814. The water inlet assembly 8 can add water to the crushing chamber 31, the inner bucket 30 and the litter box assembly 4.

[0110] The second water outlet 813 is also equipped with a rotating nozzle 815. The rotating nozzle 815 has a spiral blade. When the water flow comes into contact with the spiral blade, the water flow pushes the spiral blade to rotate. At the same time, the spiral blade spreads the water flow in all directions, thereby increasing the spray range of the water and cleaning the entire inner chamber.

[0111] refer to Figure 9 and Figure 14 The litter box assembly 4 includes a dry litter box 41 or a washable litter box 42, forming an optional component that can be selected from either the dry litter box 41 or the washable litter box 42.

[0112] Dry litter box 41 is used to hold non-washable cat litter, while washable litter box 42 is used to hold washable cat litter. Users can choose different litter boxes according to the type of cat litter.

[0113] refer to Figure 15 The wall of the washable litter box 42 is provided with a first perforated part 421. The first perforated part 421 is used for draining water and removing dirt or for water to enter. When washing the litter, water can enter through the first perforated part 421. The bottom of the washable litter box 42 is provided with a water stirring plate 422. When the washable litter box 42 rotates, the water stirring plate 422 can stir the water in the inner bucket 30, thereby forming a certain water flow and increasing the washing effect of the litter.

[0114] During litter cleaning, the water inlet component 8 adds water to the inner tub 30, and the litter box 42 rotates under the drive of the second motor 33 to agitate and clean the litter. The rotation can be unidirectional or reciprocating. The water in the inner tub 30 flows into the litter box 42 through the first perforated part 421. When the water level in the inner tub 30 reaches the preset value, the water inlet component 8 stops adding water or reduces the water level. After the litter is cleaned, the water is drained away through the drain pipe assembly 34.

[0115] When the cat litter is spun dry, the second motor 33 drives the water-washing litter box 42 to rotate at high speed in one direction, quickly spun dry the water in the cat litter. The spun water is thrown out from the first hollow part 421 of the water-washing litter box 42 to the inner bucket 30 and discharged through the drain pipe assembly 34.

[0116] In addition, since the second water outlet 813 is equipped with a rotating nozzle 815, it can spray water in all directions, thereby cleaning the inner chamber 10, shovel 71, guide plate 53 and other parts and components of the outer shell 1.

[0117] refer to Figure 6 , Figure 16 and Figure 17 The cat litter box also includes an intake fan 51 and an exhaust fan 52. The exhaust end of the intake fan 51 is equipped with a heating wire 511, which can generate hot air. The side wall of the main body 11 is provided with corresponding air inlets and outlets.

[0118] It also includes a flow guide plate 53, which can be placed above the litter tray assembly 4 or above the inner bucket 30;

[0119] The air guide plate 53 includes a first air guide portion 531 and an annular portion 532;

[0120] The first air guide section 531 is connected to the air intake fan 51 and can guide the airflow into the litter box assembly 4;

[0121] The annular portion 532 is inclined inward;

[0122] The fan can freshen the air and also be used to dry the cat litter. When the cat litter box 42 is washed with water, after the cat litter is washed, the air intake fan 51 blows hot air into the cat litter box 42 to dry it.

[0123] Considering that some cats have the habit of urinating and defecating along the edge of the litter box, the annular portion 532 of the guide plate 53 is inclined inward to facilitate the flow of cat urine and feces to the litter box assembly 4. Furthermore, when cleaning the inner chamber 10, it facilitates the flow of water to the litter box assembly 4 or the inner bucket 30.

[0124] refer to Figures 18 to 20 The cat litter box also includes a hair drying component 6, which can be placed above the litter tray component 4 or above the inner bucket 30.

[0125] Hair drying assembly 6 includes a drying basin base 61 and a drying hood 62;

[0126] The drying hood 62 includes a second air guide 621 and a hood surface 622;

[0127] The second air guide section 621 is connected to the air intake fan 51 and can guide the airflow to the drying tray 61.

[0128] The cover 622 is provided with a third perforation 623, which can guide the airflow to the inner chamber;

[0129] When using the hair drying assembly 6, the air guide plate 53 needs to be removed first, and then the hair drying assembly 6 can be placed. After the cat has been bathed, the cat can be placed on the hair drying assembly 6, and the air intake fan 51 will start to deliver airflow, which can also deliver hot air. The airflow flows to the drying tray 61 under the guidance of the second air guide 621. Due to the obstruction of the drying tray 61, the airflow is turned upward, thereby blowing air onto the cat and drying its fur.

[0130] refer to Figures 3 to 5 The cat litter box also includes an electric inner door assembly 2; the electric inner door assembly 2 corresponds to the position of the inlet and outlet 121 and is used to open and close the inlet and outlet 121; for example, when cleaning cat feces, washing cat litter, or cleaning the inner compartment 10, the inlet and outlet 121 can be closed.

[0131] The electric interior door assembly 2 includes an active revolving door 21, a driven revolving door 22, a torsion spring 23, a gear 24, a first motor 25, and a transmission gear 26;

[0132] The active revolving door 21 is linked with gear 24, which can be an external gear. Gear 24 meshes with transmission gear 26, which is connected to the first motor 25.

[0133] The driven revolving door 22 is rotatably connected to the gear 24. The torsion spring 23 is sleeved on the top or bottom of the gear 24. The first end 231 of the torsion spring 23 is connected to the driving revolving door 21, and the second end 232 of the torsion spring 23 is connected to the driven revolving door 22. Both the driving revolving door 21 and the driven revolving door 22 are provided with corresponding insertion holes to connect the end of the torsion spring 23.

[0134] The first motor 25 drives the gear 24 to rotate, thereby driving the active revolving door 21 to rotate. Under the action of the torsion spring 23, the driven revolving door 22 rotates accordingly. The torsion spring 23 is set between the active revolving door 21 and the driven revolving door 22 for transmission, so that the driven revolving door 22 has a certain buffering effect. For example, when a cat or a person's hand is bumped, the buffering effect of the torsion spring 23 reduces the impact and pinching injury.

[0135] Gear 24 has fewer than one tooth per revolution. When the first motor 25, connected to the transmission gear 26, drives gear 24 to rotate, because gear 24 has fewer than one tooth per revolution, it reaches a certain angle without teeth, limiting excessive rotation of the first motor 25. Since gear 24 is connected to the active revolving door 21, it limits the travel of the active revolving door 21. This prevents the first motor 25 from over-closing the door, which could cause injury to a cat or a person's hand.

[0136] The bottom of the outer casing 1 is equipped with casters 9 for easy movement of the cat litter box.

[0137] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
