Description

Technical Field

[0001] The invention belongs to the technical field of pet equipment, and in particular relates to a self-cleaning intelligent cat litter box and a cleaning method thereof. Background Art

[0002] With the acceleration of urbanization and the improvement of living standards, the requirements for the environment for raising pets at home are getting higher and higher. As a popular household pet worldwide, cats have their own unique personality. Cats are clean and vigilant animals, and they will bury their excrement after defecation. Nowadays, families who keep cats will first prepare a cat litter box, then train the cat to defecate in it, and manually shovel away the cat feces and clean up the excrement after defecation.

[0003] The existing commonly used cat litter boxes have the following shortcomings: 1. Cleaning the excrement in the cat litter box is a time-consuming and laborious task. If the cat feces are not cleaned regularly, a pungent smell will be produced, especially in the home, affecting the indoor air and environment; 2. The existing cat litter boxes can only simply solve the problem of cat excretion, and cannot realize the function of intelligent separation and collection of cat feces; 3. The existing cat litter box lacks the automatic control function of separating cat litter and cat feces, and lacks the function of monitoring cat activities and health status; 4. When cleaning the cat litter box, the cat litter is often cleaned up together, causing waste of cat litter. In response to this technical problem, the improved cat litter box has the function of automatically collecting cat feces, which can reduce the waste of cat litter in the process of cleaning cat feces.

[0004] For example, China Patent published a utility model patent named "Smart Cat Litter Basin" (application number: CN201920240697.8) on February 26, 2019, which includes a base and a cover. Generally, a middle frame structure is set in the base, a ring is installed in the middle frame structure, and the separation barrel rotates in the installation ring. However, the overall thickness of the base is large, the weight is heavy, and the cover is prone to deformation. Summary of the invention

[0005] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and to provide a self-cleaning intelligent cat litter box and a cleaning method thereof, so as to increase the bearing capacity of the entire device and avoid deformation of the upper cover and the base. In addition, the combined support structure and the upper cover are sealed and connected, and the combined support structure and the base are sealed and connected, which is convenient for the subsequent self-cleaning operation of the separation barrel. The sewage discharged from the separation barrel is not easy to enter the base, thereby achieving a waterproof effect.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A self-cleaning intelligent cat litter box, characterized in that it includes a base, an upper cover, a separation barrel and a combined support structure, wherein the separation barrel is arranged in a cavity formed between the base and the upper cover, the separation barrel is provided with a feces outlet, the combined support structure limits the feces outlet, the upper cover and the base are both provided with a first embedding groove, the combined support structure is embedded in the first embedding groove, so that the combined support structure and the upper cover are sealed and connected, and the combined support structure and the base are sealed and connected. In order to increase the strength of the upper cover itself, ribs can be arranged on the inner side of the upper cover.

[0008] In the prior art, the cover body is arranged on the base, and the base supports the cover body. However, the cover body in the prior art is in an arc shape, and the cover body is prone to deformation. Therefore, the present invention adopts a combined support structure to replace the middle frame in the prior art. The combined support structure is supported between the upper cover and the base. The force received by the upper cover can be transmitted to the base through the combined support structure. At the same time, the force received by the upper cover can be directly transmitted to the base, thereby increasing the bearing capacity of the entire device. The combined support structure is embedded in the first embedding groove of the upper cover. The combined support structure supports and strengthens the inner side of the upper cover. At the same time, the combined support structure is embedded in the first embedding groove of the base. The combined support structure supports and strengthens the inner side of the base, thereby avoiding deformation of the upper cover and the base. The present invention cancels the middle frame, so that the thickness of the base is thinner, thereby making the base lighter, and facilitating the rapid assembly of the self-cleaning intelligent cat litter box. Moreover, the combined support structure and the upper cover are sealed together, and the combined support structure and the base are sealed together, which facilitates the subsequent self-cleaning operation of the separation barrel. The sewage discharged from the separation barrel is not easy to enter the base, thus achieving a waterproof effect.

[0009] Furthermore, the combined support structure can adopt a whole plate, but the whole plate is not easy to demould. In view of this technical problem, the combined support structure of the present invention includes two fixedly connected support plates. The support plate of the present invention can be manufactured by a pair of molds in one piece. The support plate and the first embedded groove match each other. The two support plates are arranged symmetrically in the center. The support plate is provided with a notch, which is in the shape of an arc, and the feces outlet is limited in the notch. The support plate of the present invention has a simple structure, is easy to manufacture, and has low cost, which is conducive to reducing the manufacturing cost of the entire self-cleaning intelligent cat litter box. In addition, ultraviolet lamps and ozone negative ion generators can be installed on the support plate to disinfect and deodorize the feces outlet. Reinforcing ribs arranged horizontally and vertically are arranged on the inner side of the support plate to increase the strength of the support plate and give full play to the supporting effect of the combined support structure on the upper cover and the base. The support plate of the present invention is provided with an installation port, and a connecting plate can be embedded in the installation port, and then the connecting plate is fixed in the installation port by screws, so that the two support plates are fixedly connected. The top and bottom of the support plate of the present invention are both provided with mounting protrusions, the mounting protrusions are provided with mounting holes, the base and the upper cover are both provided with connecting columns, and the connecting columns are arranged in the mounting holes, thereby improving the connection effect between the combined support structure and the base and the upper cover, and further improving the stability of the installation of the combined support structure.

[0010] Furthermore, since the base and the upper cover of the present invention are in an arc shape, and the support plate is a polygon, the support plate cannot completely seal the base and the upper cover. In response to this technical problem, the support plate of the present invention is provided with an inclined plate, and the inclined plate and the support plate are an integrally formed structure, and the upper cover and the base are both provided with a second embedding groove. By matching the inclined plate and the second embedding groove, the connection points between the support plate and the base and the upper cover are increased, which can not only improve the support effect of the support plate, but also make the combined support structure and the upper cover completely sealed and connected, and the combined support structure and the base completely sealed and connected.

[0011] Furthermore, the support plate is provided with at least two first roller bases, the first roller base is provided with a first roller, an annular protrusion is provided on the outer side of the feces outlet, and a mounting groove is formed between the annular protrusions. The first roller is circumferentially distributed in the mounting groove, and the first roller limits the annular protrusion. At the same time, the first roller guides the feces outlet, so as to facilitate the smooth rotation of the separation barrel.

[0012] Furthermore, a cat feces collecting box is provided between the upper cover and the base, the cat feces collecting box is provided below the feces outlet, the cat feces collecting box is fixedly connected to the combined support structure, the cat feces collecting box is provided with a garbage bag, the garbage bag is provided with a rope, the cat feces collecting box is provided with an opening, and one end of the rope passes through the opening. Cat feces are collected in the garbage bag of the cat feces collecting box. When the cat feces in the cat feces collecting box are processed, the bag opening of the garbage bag is tightened by pulling the rope extending outside the basin body, and then the cat feces collecting box is removed. Since the cat feces are wrapped in the garbage bag, the odor brought by the cat feces can be reduced. The present invention arranges a first magnet on the support plate and a second magnet on the cat feces collecting box at the same time, and the second magnet and the first magnet are attracted to each other, so that the cat feces collecting box is fixedly connected to the combined support structure. When force is applied to the cat feces collecting box, the cat feces collecting box can be removed from the basin body, and the technical solution of the first magnet and the second magnet attracting each other is adopted, which has the characteristics of low cost, simple structure and convenient operation.

[0013] Furthermore, the separation barrel is provided with a cat inlet and outlet, the separation barrel is provided with a pedal, the pedal is provided in the cat inlet and outlet, the pedal is provided with a convex block, a groove is formed between the convex block and the pedal, the inner side of the cat inlet and outlet is provided with an edge, the edge and the inner side of the separation barrel form a limiting groove, the convex block is embedded in the limiting groove, and the edge is embedded in the groove, so that the pedal is preliminarily installed at the cat inlet and outlet. A limiting plate is provided between the edge and the inner side of the separation barrel, the limiting plate is provided with a limiting hole, the convex block is provided with a limiting buckle, and the limiting buckle is clamped in the limiting hole, further increasing the limiting effect of the pedal on the separation barrel, increasing the pressure bearing capacity of the pedal, and meeting the requirements of a cat of a certain weight entering and exiting the separation barrel, and the design scheme makes the pedal detachably connected to the separation barrel, which is convenient for replacing the pedal.

[0014] Furthermore, in order to facilitate the cleaning of the separation barrel, the prior art makes the upper cover and the base detachably connected, and then the separation barrel is taken out. However, repeated installation and removal of the separation barrel is easy to damage the structure of the separation barrel. In view of this technical problem, the present invention locks the upper cover on the base, and the separation barrel performs a self-cleaning operation between the upper cover and the base, and there is no need to take out the separation barrel. The specific scheme is: the upper cover is provided with a first mounting plate, the first mounting plate is provided with a first fixing block, the base is provided with a second mounting plate, the second mounting plate is provided with a second fixing block, and the first fixing block and the second fixing block are fixedly connected by screws, so that the upper cover and the base are locked. In order to prevent impurities from entering the upper cover and the base, the first mounting plate and the second mounting plate are both provided with through holes, and a notch is provided between the upper cover and the base, and a sealing plate is embedded in the notch. The sealing plate is provided with a limiting column, and the limiting column is limited in the through hole. The sealing plate has a decorative effect and can block impurities to prevent impurities from entering the upper cover and the base. The end of the limiting column of the present invention is provided with a clamping portion, and the limiting column is provided with an opening to facilitate the deformation of the limiting column itself. When the limiting column is inserted into the through hole, the clamping portion is squeezed, so that the limiting column is deformed, the clamping portion passes through the through hole, and is clamped on the first mounting plate and the second mounting plate.

[0015] Furthermore, the base is provided with a motor, and the motor drives the separation barrel to rotate in the cavity formed between the base and the upper cover, and the feces outlet rotates on the combined support structure. In the prior art, the motor is provided with a motor shaft, and a main gear is installed on the motor shaft, and a driven gear belt is provided on the outer side of the separation barrel, and the driven gear belt matches the main gear, so that the motor drives the separation barrel to rotate. Based on this structure, the present invention installs a travel switch in the base, and a convex point is provided at the bottom of the separation barrel. The number of revolutions of the separation barrel can be counted by pressing the travel switch with the convex point, which is convenient for accurately returning the separation barrel to its original position. In view of the travel switch, the present invention sets the motor at an angle, and a motor seat is provided at the bottom of the motor, and the motor seat is fixed horizontally in the base. In order to ensure the safety of the rotation of the separation barrel, a second roller base is provided in the base, and the second roller base is provided with a second roller, and the second roller supports and guides the outer side of the separation barrel.

[0016] Furthermore, due to the sealed connection between the combined support structure and the upper cover, and the sealed connection between the combined support structure and the base of the present invention, the combined support structure has a waterproof effect. Therefore, the present invention can perform self-cleaning operations on the separation barrel without dismantling the separation barrel. The specific plan is as follows: a shit scooping structure is fixedly connected to the interior of the separation barrel, and the end of the shit scooping structure extends into the shit outlet. The shit scooping structure is provided with a mesh. The bottom of the shit scooping structure is detachably connected with a baffle, which blocks the mesh and seals the mesh. The bottom of the shit scooping structure is provided with a limiting protrusion, and a sliding groove is formed between the limiting protrusions. The baffle moves in a direction along the width direction of the shit scooping structure in the sliding groove. When the baffle does not block the mesh holes of the shit-scooping structure, a cleaning agent is added to the separation barrel and the separation barrel is left stationary; when the baffle blocks the mesh holes of the shit-scooping structure, the separation barrel is controlled to rotate, and the shit-scooping structure can be used to discharge the sewage in the separation barrel, thereby achieving a self-cleaning effect of the separation barrel. There is no need to remove the separation barrel from the base, and the sewage is discharged from the shit outlet of the separation barrel. Due to the water-blocking effect of the combined supporting structure, the sewage is not easy to enter the inside of the base, and cleaning is convenient and fast without causing damage to the structure of the separation barrel itself.

[0017] Furthermore, a decorative plate is provided on the top of the upper cover, which is equivalent to a cat's ear and improves the aesthetics.

[0018] A method for cleaning a self-cleaning intelligent cat litter box, characterized in that it comprises the following steps:

[0019] a. A cat feces collection box is installed between the upper cover and the base. The cat feces collection box is arranged below the feces outlet. The cat feces collection box is fixed to the combined support structure by a magnet.

[0020] b. Separation of cat litter and feces: When the smart litter box is turned on, the motor drives the separation bucket to rotate in the cavity formed between the base and the upper cover. The feces shoveling structure separates the cat litter and feces while shoveling the feces. The cat litter passes through the mesh of the feces shoveling structure and falls into the separation bucket. The feces are discharged from the separation bucket along the feces shoveling structure and fall into the cat feces collection box. This operation separates the cat litter and feces, making it easier to clean the feces and keep the bucket clean.

[0021] c. Discharge the cat litter from the separation bucket: When all the feces are discharged from the separation bucket, stop the smart cat litter box, remove the cat feces collection box, centrally process the feces, and then slide the baffle into the sliding groove formed between the limiting protrusions at the bottom of the feces shoveling structure. The baffle blocks the mesh of the feces shoveling structure, and then install the cat feces collection box between the upper cover and the base. Start the smart cat litter box again, and the motor drives the separation bucket to rotate in the cavity formed between the base and the upper cover. At this time, the cat litter is discharged from the separation bucket along the feces shoveling structure and falls into the cat feces collection box. The purpose of this operation is to centrally collect the used cat litter, which can be cleaned and reused repeatedly.

[0022] d. Clean the separation barrel: when all the cat litter is discharged from the separation barrel, stop the smart cat litter box, remove the cat feces collection box, centrally process the cat litter, remove the baffle from the sliding groove, add clean water to the inside of the separation barrel, add a cleaning agent to the inside of the separation barrel, let the separation barrel stand, and after standing, start the smart cat litter box again. Water passes through the mesh of the feces scooping structure and falls into the separation barrel to clean the feces scooping structure and the separation barrel. After cleaning, stop the smart cat litter box, slide the baffle into the sliding groove formed between the limiting protrusions at the bottom of the feces scooping structure, the baffle blocks the mesh of the feces scooping structure, and then install the cat feces collection box between the upper cover and the base. Start the smart cat litter box again, and the motor drives the separation barrel to rotate in the cavity formed between the base and the upper cover. At this time, the sewage in the separation barrel is discharged from the separation barrel along the feces scooping structure and discharged into the cat feces collection box. The separation barrel can be self-cleaned without removing the separation barrel from the base. Sewage is discharged from the discharge port of the separation barrel. Due to the water-blocking effect of the combined support structure, sewage is not easy to enter the base. In addition, cleaning is convenient and fast without causing damage to the structure of the separation barrel itself.

[0023] e. Remove the cat feces collection box, centrally treat the sewage, and then dry the inside of the separation barrel. A household hair dryer can be used to dry the inside of the separation barrel, and a dry cloth is used to wipe the outside of the combined support structure. Then the cat feces collection box is cleaned, and then the cat feces collection box is wiped dry. The cat feces collection box is then installed between the upper cover and the base to complete the cleaning operation, so that the inside of the self-cleaning smart cat litter box is clean.

[0024] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0025] 1. In the prior art, the cover body is arranged on the base, and the base supports the cover body. However, the cover body in the prior art is in an arc shape, and the cover body is prone to deformation. Therefore, the present invention adopts a combined support structure to replace the middle frame in the prior art. The combined support structure is supported between the upper cover and the base. The force received by the upper cover can be transmitted to the base through the combined support structure. At the same time, the force received by the upper cover can be directly transmitted to the base, thereby increasing the bearing capacity of the entire device. The combined support structure is embedded in the first embedding groove of the upper cover. The combined support structure supports and strengthens the inner side of the upper cover. At the same time, the combined support structure is embedded in the first embedding groove of the base. The combined support structure supports and strengthens the inner side of the base, thereby avoiding deformation of the upper cover and the base. The present invention cancels the middle frame, so that the thickness of the base is thinner, thereby making the base lighter, and facilitating the rapid assembly of the self-cleaning intelligent cat litter box. Moreover, the combined support structure and the upper cover are sealed together, and the combined support structure and the base are sealed together, which facilitates the subsequent self-cleaning operation of the separation barrel. The sewage discharged from the separation barrel is not easy to enter the base, thus achieving a waterproof effect.

[0026] 2. The combined support structure can use a whole plate, but the whole plate is not easy to demold. In response to this technical problem, the combined support structure of the present invention includes two fixedly connected support plates. The support plate of the present invention can be manufactured by a pair of molds in one piece. The support plate and the first embedded groove match each other. The two support plates are arranged symmetrically in the center. The support plate is provided with a notch, which is in the shape of an arc, and the feces outlet is limited in the notch. The support plate of the present invention has a simple structure, is easy to manufacture, and has low cost, which is conducive to reducing the manufacturing cost of the entire self-cleaning intelligent cat litter box. In addition, ultraviolet lamps and ozone negative ion generators can be installed on the support plate to disinfect and deodorize the feces outlet. Reinforcing ribs arranged horizontally and vertically are arranged on the inner side of the support plate to increase the strength of the support plate and give full play to the supporting effect of the combined support structure on the upper cover and the base. The support plate of the present invention is provided with an installation port, and a connecting plate can be embedded in the installation port, and then the connecting plate is fixed in the installation port by screws, so that the two support plates are fixedly connected. The top of the support plate of the present invention is provided with a mounting protrusion, the mounting protrusion is provided with a mounting hole, the base and the upper cover are both provided with connecting columns, and the connecting columns are arranged in the mounting holes, thereby improving the connection effect between the combined support structure and the base and the upper cover, and further improving the stability of the installation of the combined support structure.

[0027] 3. A cat feces collecting box is provided between the upper cover and the base, the cat feces collecting box is provided below the feces outlet, the cat feces collecting box is fixedly connected to the combined support structure, the cat feces collecting box is provided with a garbage bag, the garbage bag is provided with a rope, the cat feces collecting box is provided with an opening, and one end of the rope passes through the opening. Cat feces are collected in the garbage bag of the cat feces collecting box. When the cat feces in the cat feces collecting box are processed, the bag opening of the garbage bag is tightened by pulling the rope extending outside the basin body, and then the cat feces collecting box is removed. Since the cat feces are wrapped in the garbage bag, the odor brought by the cat feces can be reduced. The present invention arranges a first magnet on the support plate and a second magnet on the cat feces collecting box at the same time. The second magnet and the first magnet are attracted to each other, so that the cat feces collecting box is fixedly connected to the basin body. When force is applied to the cat feces collecting box, the cat feces collecting box can be removed from the basin body. Moreover, the technical solution of the first magnet and the second magnet attracting each other is adopted, which has the characteristics of low cost, simple structure and convenient operation.

[0028] 4. In the specific cleaning process, cat litter and feces are separated first, so as to facilitate centralized cleaning of feces and keep the bucket clean. Then the cat litter is discharged from the separation bucket, and the cat litter can be cleaned and reused. At this time, there is no cat litter and feces in the separation bucket, so the separation bucket can be self-cleaned, the baffle is removed from the sliding groove, and then clean water is added to the inside of the separation bucket, and then a cleaning agent is added to the inside of the separation bucket, and the separation bucket is left to stand. After standing, the smart cat litter box is turned on again, and water passes through the mesh of the feces shoveling structure and falls into the separation bucket, and the feces shoveling structure and the separation bucket are cleaned. After the cleaning is completed, the smart cat litter box is stopped, and then the baffle is slid into the sliding groove formed between the limiting protrusions at the bottom of the feces shoveling structure. The baffle blocks the mesh of the feces shoveling structure, and then a cat feces collection box is installed between the upper cover and the base. The smart cat litter box is turned on again, and the motor drives the separation bucket to rotate in the cavity formed between the base and the upper cover. At this time, the sewage in the separation bucket is discharged from the separation bucket along the feces shoveling structure and discharged into the cat feces collection box. This operation achieves the effect of self-cleaning of the separation barrel without removing the separation barrel from the base. Sewage is discharged from the discharge port of the separation barrel. Due to the water-blocking effect of the combined supporting structure, sewage is not easy to enter the inside of the base. In addition, cleaning is convenient and fast without causing damage to the structure of the separation barrel itself. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] like Figures 1 to 15 As shown, a self-cleaning intelligent cat litter box of the present invention comprises a base 1, an upper cover 2, a separation barrel 3 and a combined support structure 4. The separation barrel 3 is arranged in a cavity formed between the base 1 and the upper cover 2. The separation barrel 3 is provided with a feces outlet 5. The combined support structure 4 limits the feces outlet 5. The inner sides of the upper cover 2 and the base 1 are both provided with a first embedding groove 6. The combined support structure 4 is embedded in the first embedding groove 6, so that the combined support structure 4 and the upper cover 2 are sealed and connected, and the combined support structure 4 and the base 1 are sealed and connected. In order to increase the strength of the upper cover 2 itself, ribs 56 can be provided on the inner side of the upper cover 2.

[0048] In the prior art, the cover is arranged on the base, and the base supports the cover. However, the cover in the prior art is in an arc shape, and the cover is prone to deformation. Therefore, the present invention adopts a combined support structure 4 to replace the middle frame in the prior art. The combined support structure 4 is supported between the upper cover 2 and the base 1. The force received by the upper cover 2 can be transmitted to the base 1 through the combined support structure 4. At the same time, the force received by the upper cover 2 can be directly transmitted to the base 1, thereby increasing the bearing capacity of the entire device. The combined support structure 4 is embedded in the first embedding groove 6 of the upper cover 2. The combined support structure 4 supports and strengthens the inner side of the upper cover 2. At the same time, the combined support structure 4 is embedded in the first embedding groove 6 of the base 1. The combined support structure 4 supports and strengthens the inner side of the base 1, thereby avoiding deformation of the upper cover 2 and the base 1. The present invention cancels the middle frame, so that the thickness of the base 1 is thinner, thereby making the base 1 lighter, and facilitating the rapid assembly of the self-cleaning intelligent cat litter box. Moreover, the combined support structure 4 and the upper cover 2 are sealed together, and the combined support structure 4 and the base 1 are sealed together, which is convenient for the subsequent self-cleaning operation of the separation barrel 3. The sewage discharged from the separation barrel 3 is not easy to enter the base 1, which has a waterproof effect.

[0049] The combined support structure 4 can be made of a whole plate, but the whole plate is not easy to demold. In response to this technical problem, the combined support structure 4 of the present invention includes two fixedly connected support plates 7. The support plates 7 of the present invention can be manufactured by a pair of molds in one piece. The support plates 7 and the first embedding grooves 6 are matched. The two support plates 7 are symmetrically arranged. The support plates 7 are provided with notches 8. The notches 8 are in the shape of a circular arc, and the feces outlet 5 is limited in the notches 8. The support plate 7 of the present invention has a simple structure, is easy to manufacture, and has low cost, which is conducive to reducing the manufacturing cost of the entire self-cleaning intelligent cat litter box. In addition, the ultraviolet lamp and the ozone negative ion generator can be installed on the support plate 7. The support plate 7 serves as a carrier for installation. The ultraviolet lamp and the ozone negative ion generator disinfect and deodorize the feces outlet 5. The inner side of the support plate 7 is provided with reinforcing ribs arranged horizontally and vertically to increase the strength of the support plate 7 and give full play to the supporting effect of the combined support structure 4 on the upper cover 2 and the base 1. The support plate 7 of the present invention is provided with an installation port, and a connecting plate 58 can be embedded in the installation port (see for details). Figure 6 ), and then the connecting plate 58 is fixed in the installation opening by screws, so that the two support plates 7 are fixedly connected. The top and bottom of the support plate 7 of the present invention are both provided with mounting protrusions, and the mounting protrusions are provided with mounting holes. The inner sides of the base 1 and the upper cover 2 are both provided with connecting columns, and the connecting columns are arranged in the mounting holes, so as to improve the connection between the combined support structure 4 and the base 1 and the upper cover 2, and thus improve the stability of the installation of the combined support structure 4.

[0050] Since the base 1 and the upper cover 2 of the present invention are in an arc shape, and the support plate 7 is a polygon, the support plate 7 cannot completely seal the base 1 and the upper cover 2.
