Description

Technical Field

[0001] This application relates to the field of pet supplies, and specifically to a cat litter box. Background Art

[0002] Cat litter is a sanitary product designed to provide a convenient place for cats, usually made of materials such as minerals, plant fibers, and silica gel. A cat litter box is a container for holding cat litter, which facilitates the burying after the cat excretes. The use of cat litter and cat litter box can not only keep the indoor environment clean, but also help the owner easily manage the cat's excrement.

[0003] In the prior art, cat litter is usually directly thrown away after use and needs to be replaced with new ones, which causes a large amount of waste of cat litter. At the same time, there are also problems of manpower waste and dust annoyance. The reason for manpower waste is that every time the cat litter is replaced, the owner needs to clean, pour out the old litter and add new litter, which is a cumbersome and time-consuming process. The dust annoyance stems from the fact that a large amount of dust is easily generated during the pouring and adding of cat litter, which not only affects the environmental hygiene, but also may cause respiratory problems, and is not good for the health of both the owner and the cat.

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In the description of the present application: Unless otherwise specified, "a plurality of" means two or more. Terms such as "first", "second", "third", etc. in the present application are intended to distinguish the objects being referred to and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.); Figure 11 The entire structure of the filtering part is not shown (third embodiment); Figure 13 The flushing part is not shown (reference can be made to the drawings of other embodiments).

[0048] Refer to Figure 1 , Figure 4 , Figure 9 and Figure 11 , the present application discloses a cat litter box, which includes a basin body 1, a stirring part 2 connected to the basin body 1, a flushing part 4 connected to the basin body 1, and a filtering part 3 connected to the basin body 1. The basin body 1 includes an accommodating groove 11 for accommodating cat litter. The flushing part 4 is used to flush the cat litter in the accommodating groove 11 with a flushing liquid. The stirring part 2 is used to stir the cat litter in the accommodating groove 11, and the flushing part 4 and the stirring part 2 cooperate to crush the cat feces in the cat litter. The filtering part 3 is used to filter out the crushed cat feces from the basin body 1 in cooperation with the flushing of the flushing part 4.

[0049] After the cat uses the cat litter, the stirring part 2 starts to stir the cat litter in the receiving tank 11, and crushes the cat feces by mechanical stirring. At the same time, the flushing part 4 is activated, and the cat litter in the receiving tank 11 is flushed with the flushing liquid. The function of the flushing liquid is to soften the cat feces so that it detaches from the cat litter. The structure of the cat feces becomes loose and is easily further crushed by the stirring part 2. Under the continuous action of the stirring part 2, the cat feces are decomposed into smaller pieces. The flushing part 4 continues to flush, and the filtering part 3 separates these cat feces pieces from the cat litter and discharges them outside the basin body 1. Through this process, the cat feces in the cat litter are effectively removed, enabling the cat litter to be used again, reducing the waste of cat litter, and improving the utilization efficiency of the cat litter.

[0050] In some embodiments, a drying device can be provided inside the basin body 1 to dry the cat litter after cleaning, facilitating the cat to continue using it. The drying device can be an electric heating tube heating system that dries the cat litter with the heat generated by the electric heating tubes; it can also be a hot air circulation system that circulates and blows the heated air into the cat litter through a built-in fan to accelerate the drying process of the cat litter. These drying devices can not only quickly and effectively dry the cat litter but also avoid the generation of odors and the growth of bacteria due to moisture, further improving the hygiene level of the cat litter box.

[0051] In some embodiments, the flushing liquid can be water or other cleaning liquids. For example, the flushing liquid can be a cleaning agent containing a disinfecting component that can effectively kill bacteria and viruses during the cleaning process to ensure the hygienic environment of the cat litter box.

[0052] In some embodiments, the cat litter can be made of plastic particles, which are convenient for repeated use after cleaning.

[0053] In some embodiments, the stirring part 2 can stir the cat litter in the entire receiving tank 11 and cooperate with the flushing of the flushing part 4 to crush the cat feces.

[0054] In some embodiments, the receiving tank 11 includes a first area 111 and a second area 112. The stirring part 2 includes a spiral pushing rod 21 rotatably connected to the tank wall of the receiving tank 11 and a motor 22 connected to the basin body 1 and used to drive the spiral pushing rod 21 to rotate. The motor 22 drives the spiral pushing rod 21 to rotate forward or backward so that the spiral plate 211 of the spiral pushing rod 21 repeatedly transfers and stirs the cat litter in the first area 111 and the second area 112.

[0055] The motor 22 drives the spiral push rod 21 to continuously rotate forward and reverse at a set time, repeatedly transferring and agitating the cat litter in the receiving groove 11 between the first area 111 and the second area 112. During this process, the spiral plate 211 of the spiral push rod 21 pushes the cat litter, causing it to move back and forth between the two areas, resulting in a sufficient stirring effect. With the flushing of the flushing part 4, the flushing liquid can infiltrate the cat litter, soften the cat feces therein and gradually crush them. Due to the continuous agitation of the spiral push rod 21, the cat feces are effectively decomposed into small pieces and discharged out of the basin body 1 through the filtering part 3.

[0056] In addition, compared with the design where the spiral push rod 21 fills the entire receiving groove 11, in this embodiment, the spiral push rod 21 only needs to enable the cat litter to be transferred between the first area 111 and the second area 112. This makes the spiral push rod 21 smaller in volume and lower in power, reducing the complexity and energy consumption of the device.

[0057] Reference Figures 4 - 7 , in some embodiments, a conveying groove 113 is formed in the bottom wall of the receiving groove 11. The two ends of the spiral push rod 21 are respectively rotatably connected to the groove walls at the two ends of the conveying groove 113. The length extension direction of the spiral push rod 21 is arranged along the length extension direction of the conveying groove 113. The motor 22 is connected to the outer wall of the basin body 1, the output shaft of the motor 22 is connected to the spiral push rod 21, a blocking plate 5 is connected to the bottom wall of the receiving groove 11, the blocking plate 5 divides the receiving groove 11 into a first area 111 and a second area 112, the blocking plate 5 is located above the conveying groove 113, and the two ends of the spiral push rod 21 are respectively located in the first area 111 and the second area 112;

[0058] A support ring is connected to the bottom of the basin body 1 along its circumferential direction. The support ring and the bottom wall of the receiving groove 11 enclose a filtering cavity 121, and the filtering cavity 121 is located at the bottom of the receiving groove 11;

[0059] The filtering part 3 includes a filter screen 31 connected to the bottom wall of the conveying groove 113, a filter bin 33 connected to the outer groove wall of the conveying groove 113 far from the receiving groove 11, and a sewage discharge pipe 32 communicating with the filter bin 33. The filter screen 31 constitutes one side wall of the filter bin 33, and the filter bin 33 is located in the filtering cavity 121;

[0060] The flushing part 4 includes a plurality of flushing pipes 41 connected to the basin body 1. One end of the flushing pipe 41 extends into the receiving groove 11 to enable the flushing liquid to flush the cat litter in the receiving groove 11, and the plurality of flushing pipes 41 are uniformly arranged along the circumferential direction of the basin body 1.

[0061] The blocking plate 5 separates the receiving tank 11 into a first area 111 and a second area 112, so that the cat litter in the receiving tank 11 forms two independent spaces under the blocking of the blocking plate 5. The two ends of the spiral push rod 21 are respectively located in the first area 111 and the second area 112, spanning the two areas, effectively stirring and transferring the cat litter in the receiving tank 11 between the two areas. Due to the existence of the blocking plate 5, the spiral push rod 21 can achieve sufficient stirring in the two areas without covering the entire bottom of the receiving tank 11;

[0062] The motor 22 drives the spiral push rod 21 to rotate forward and flip, and the cat litter is continuously transferred and stirred in the first area 111 and the second area 112. In conjunction with the flushing of the flushing pipe 41, the flushing liquid soaks the cat litter, softens the cat feces and gradually breaks them up. During the flushing process, the cat feces are broken into small fragments, which enter the filter bin 33 through the filter screen 31 at the bottom of the receiving tank 11 and are finally discharged from the sewage pipe 32;

[0063] The spiral push rod 21 of this design is small in size and is installed in a local area at the bottom of the receiving tank 11, which will not affect the use of the cat. By continuously stirring and transferring the cat litter in the first area 111 and the second area 112, the stirring and cleaning efficiency is effectively improved.

[0064] refer to Figures 4 - 7 The receiving tank 11 is connected with a shielding plate 42 located just above the outlet of the flushing pipe 41, and there is a gap between the shielding plate 42 and the outlet of the flushing pipe 41. The shielding plate 42 blocks the flushing liquid flushed out of the flushing pipe 41, so that the flushing liquid flows out along the peripheral side (gap) of the shielding plate 42, which is conducive to the flushing liquid spraying along the bottom of the receiving tank 11, and at the same time increases the flow rate of the flushing liquid and improves the flushing effect.

[0065] In some embodiments, the other end of the flushing pipe 41 can be connected to a tap water pipe, and the flushing pipe 41 can also be connected to a container of flushing liquid, such as a detergent container with a disinfection function or a deodorization function; the sewage pipe 32 can be connected to a sewer.

[0066] refer to Figures 9 - 11, in some embodiments, a conveying groove 113 is formed in the bottom wall of the accommodating groove 11. The two ends of the spiral pushing rod 21 are respectively rotatably connected to the groove walls at the two ends of the conveying groove 113. The length extension direction of the spiral pushing rod 21 is arranged along the length extension direction of the conveying groove 113. The motor 22 is connected to the outer wall of the basin body 1, and the output shaft of the motor 22 is connected to the spiral pushing rod 21. Two blocking plates 5 are connected to the bottom wall of the accommodating groove 11. The two blocking plates 5 divide the accommodating groove 11 into two first regions 111 and a second region 112. The two first regions 111 are respectively located on both sides of the second region 112. The blocking plate 5 is located above the conveying groove 113. The spiral direction of the spiral plate 211 at one end of the spiral pushing rod 21 is opposite to the spiral direction of the spiral plate 211 at the other end. The lengths of the two spiral plates 211 are equal and respectively account for half of the length of the spiral pushing rod 21. The two ends of the spiral plate 211 are respectively located in the first region 111 and the second region 112;

[0067] A support ring is connected to the bottom of the basin body 1 along its circumferential direction. The support ring and the bottom wall of the accommodating groove 11 enclose a filtering cavity 121, and the filtering cavity 121 is located at the bottom of the accommodating groove 11;

[0068] The filtering part 3 includes a filter screen 31 connected to the bottom wall of the conveying groove 113, a filter bin 33 connected to the outer groove wall on the side of the conveying groove 113 away from the accommodating groove 11, and a sewage discharge pipe 32 communicating with the filter bin 33. The filter screen 31 forms one side wall of the filter bin 33, and the filter bin 33 is located in the filtering cavity 121;

[0069] The flushing part 4 includes a plurality of flushing pipes 41 connected to the basin body 1. One end of the flushing pipe 41 extends into the accommodating groove 11 to enable the flushing liquid to flush the cat litter in the accommodating groove 11. The plurality of flushing pipes 41 are uniformly arranged along the circumferential direction of the basin body 1.

[0070] Compared with the previous embodiment, in this embodiment, the accommodating groove 11 is divided into two first regions 111 and a second region 112 by two blocking plates 5. The two first regions 111 are respectively located on both sides of the second region 112. The design of the spiral pushing rod 21 is such that the spiral direction of the spiral plate 211 at one end is opposite to the spiral direction of the spiral plate 211 at the other end. In this way, under the drive of the motor 22, the two spiral plates 211 can simultaneously transfer and stir the cat litter from the two first regions 111 to the second region 112, or transfer and stir in the opposite direction;

[0071] The motor 22 drives the screw push rod 21 to rotate forward or reversely. The two screw plates 211 of the screw push rod 21 respectively transfer and stir the cat litter in the first area 111 and the second area 112 repeatedly. During this process, the multiple flushing pipes 41 of the flushing part 4 continuously spray the flushing liquid to flush the cat litter, so that the cat feces are softened and gradually crushed. The flushing liquid brings the crushed cat feces fragments into the filter bin 33 through the filter screen 31 at the bottom of the receiving tank 11, and finally discharges from the sewage pipe 32;

[0072] The advantage of this design is that by setting the two first areas 111 and the rotation directions of the opposite screw plates 211, a more efficient cat litter transfer and stirring effect is achieved. Compared with the previous embodiment, the design with two first areas 111 and screw plates 211 with opposite rotation directions can perform two-way stirring simultaneously, significantly improving the stirring and cleaning efficiency.

[0073] Reference Figures 1 - 3 , in some embodiments, a conveying groove 113 is formed in the bottom wall of the receiving tank 11. The two ends of the screw push rod 21 are respectively rotatably connected to the groove walls at the two ends of the conveying groove 113. The length extension direction of the screw push rod 21 is arranged along the length extension direction of the conveying groove 113. The motor 22 is connected to the outer wall of the basin body 1, the output shaft of the motor 22 is connected to the screw push rod 21, the bottom wall of the receiving tank 11 is inclined, and the receiving tank 11 is divided into a first area 111 and a second area 112 along the inclination direction of the inclined surface of its own bottom wall. The two ends of the screw push rod 21 are respectively located in the first area 111 and the second area 112;

[0074] A support ring is connected to the bottom of the basin body 1 along its circumferential direction. The support ring and the bottom wall of the receiving tank 11 enclose a filtering cavity 121, and the filtering cavity 121 is located at the bottom of the receiving tank 11;

[0075] The filtering part 3 includes a filter screen 31 connected to the end wall of the conveying groove 113 and a sewage pipe 32 connected to the outer wall on the side of the conveying groove 113 away from the receiving tank 11 and used to cooperate with the filter screen 31. The filter screen 31 is located at the lowest position of the conveying groove 113, and the sewage pipe 32 is located in the filtering cavity 121;

[0076] The flushing part 4 includes multiple flushing pipes 41 connected to the basin body 1. One end of the flushing pipe 41 extends into the receiving tank 11 to enable the flushing liquid to flush the cat litter in the receiving tank 11, and the multiple flushing pipes 41 are evenly arranged along the circumferential direction of the basin body 1.

[0077] In this embodiment, the baffle 5 is not provided, and the receiving groove 11 is divided into a first region 111 and a second region 112 along the inclination direction of the inclined surface of its bottom wall. The motor 22 drives the spiral push rod 21, and both ends of the spiral push rod 21 are located in the first region 111 and the second region 112 respectively. The spiral push rod 21 conveys the cat litter at the lowest part of the receiving groove 11 upward, and the cat litter slides towards the lowest part of the receiving groove 11 under its own gravity and the flushing of the flushing pipe 41. In this way, the transfer and agitation of the cat litter between the first region 111 and the second region 112 are formed;

[0078] In actual operation, the motor 22 drives the spiral push rod 21 to rotate, pushing the cat litter from the first region 111 to the second region 112. In this process, the cat litter is continuously agitated and transferred by the action of the spiral push rod 21. When the cat litter is conveyed to a high place, due to gravity and flushing, the cat litter will slide back to the lowest part along the inclined bottom wall;

[0079] The filter screen 31 is located at the lowest part of the conveying groove 113. This design facilitates the collection and filtration of the crushed cat feces fragments. The flushing liquid filters the crushed cat feces fragments through the filter screen 31 and finally discharges them through the sewage pipe 32. Since the filter screen 31 is located at the lowest part of the conveying groove 113, it can ensure that all the cat feces fragments can be effectively filtered and discharged;

[0080] This design realizes the transfer and agitation of the cat litter by using the combination of the inclined bottom wall of the receiving groove 11 and the spiral push rod 21, simplifies the structural design, and eliminates the setting of the baffle 5.

[0081] Reference Figures 12 - 13 , in some embodiments, a partition 6 is connected to the side wall of the receiving groove 11. The partition 6 and the bottom wall of the receiving groove 11 enclose the first region 111, and the partition 6 and the side wall of the receiving groove 11 enclose the second region 112. The second region 112 is located directly above the first region 111. Both the partition 6 and the bottom wall of the receiving groove 11 are formed with inclined surfaces facing the center direction of themselves. The spiral push rod 21 is rotatably connected to the bottom wall of the receiving groove 11, and the spiral push rod 21 penetrates upward from the bottom wall of the receiving groove 11 to the second region 112. The motor 22 is connected to the outer wall of the basin body 1, the output shaft of the motor 22 is connected to the spiral push rod 21, and the spiral push rod 21 is located at the center of the partition 6 and the bottom wall of the receiving groove 11;

[0082] A support ring is connected to the bottom of the basin body 1 along its circumferential direction. The support ring and the bottom wall of the receiving groove 11 enclose a filtering cavity 121, and the filtering cavity 121 is located at the bottom of the receiving groove 11;

[0083] The filtering part 3 includes a filter screen 31 connected to the bottom wall of the accommodating groove 11, a filtering bin 33 connected to the outer groove wall of the accommodating groove 11 far from the side of the accommodating groove 11, and a sewage discharge pipe 32 communicating with the filtering bin 33. The filter screen 31 constitutes a side wall of the filtering bin 33. Both the filtering bin 33 and the motor 22 are located in the filtering cavity 121;

[0084] The flushing part 4 includes a plurality of flushing pipes 41 connected to the basin body 1. One end of the flushing pipe 41 extends into the accommodating groove 11 to enable the flushing liquid to flush the cat litter in the accommodating groove 11. The plurality of flushing pipes 41 are evenly arranged along the circumferential direction of the basin body 1.

[0085] In this embodiment, the spiral pushing rod 21 is rotatably connected to the bottom wall of the accommodating groove 11, and the spiral pushing rod 21 penetrates upward from the bottom wall of the accommodating groove 11 to the second area 112. The motor 22 drives the spiral pushing rod 21 to rotate. The spiral pushing rod 21 is located at the center of the partition plate 6 and the bottom wall of the accommodating groove 11, and stirs and transfers the cat litter up and down between the first area 111 and the second area 112 through its spiral blades (spiral plate 211);

[0086] In actual operation, when the spiral pushing rod 21 rotates forward and reverses, the cat litter in the first area 111 and the cat litter in the second area 112 repeatedly circulate up and down. Since both the partition plate 6 and the bottom wall of the accommodating groove 11 are formed with inclined surfaces facing the center direction of themselves, the cat litter is continuously stirred and transferred under the action of the spiral pushing rod 21 and slides along the inclined surface under the action of gravity, further enhancing the stirring effect.

[0087] The cat litter basin further includes a controller connected to the basin body 1. A plurality of flushing pipes 41 are all connected with solenoid valves, and a plurality of solenoid valves are all electrically connected to the controller. The side wall of the accommodating groove 11 is connected with an infrared sensor (infrared detector) for monitoring the position of the cat, and the infrared sensor is electrically connected to the controller. The motor 22 is electrically connected to the controller.

[0088] When the cat specifically uses it, the cat squats in the accommodating groove 11 of the basin body 1 to use the cat litter basin. When the cat finishes using and leaves the basin body 1, the infrared sensor on the side wall of the accommodating groove 11 will detect the departure of the cat and feed back the signal to the controller. After receiving the signal, the controller starts the cleaning program after counting down for a certain time (which can be 30 seconds), and controls the operation of the motor 22 and a plurality of solenoid valves:

[0089] The motor 22 starts to drive the screw push rod 21 to perform a cyclic motion of forward and reverse rotation. When the screw push rod 21 rotates forward, it pushes the cat litter in the first area 111 to the second area 112, and when it rotates in reverse, it pushes the cat litter in the second area 112 back to the first area 111, realizing the continuous agitation and transfer of the cat litter. At the same time, the controller controls a plurality of solenoid valves to open, and the flushing pipe 41 starts to spray the flushing liquid to flush the cat litter in the receiving tank 11. The flushing liquid infiltrates into the cat litter, softens the cat feces, makes it separate from the cat litter, and is gradually crushed under the agitation of the screw push rod 21.

[0090] In this way, the cat feces fragments are carried by the flushing liquid into the filter screen 31 on the bottom wall of the receiving tank 11. The filter screen 31 filters the cat feces fragments into the filter bin 33 and finally discharges them through the sewage pipe 32. The application of the infrared sensor ensures that the cleaning process starts automatically after the cat leaves.

[0091] Reference Figure 5 、 Figure 6 、 Figure 9 and Figure 10 In some embodiments, the baffle 5 includes two first baffles 51 integrally formed on the bottom wall of the receiving tank 11 and a second baffle 52 detachably connected between the two first baffles 51. The two first baffles 51 are respectively located on both sides of the conveying tank 113, and the second baffle 52 is located directly above the conveying tank 113. When maintenance or cleaning is required, the second baffle 52 can be removed from between the two first baffles 51. In this way, the user can conveniently remove the screw push rod 21 from the conveying tank 113 for cleaning or replacement. After the second baffle 52 is removed, the screw push rod 21 is no longer blocked. Among them, the second baffle 52 can be connected to the two first baffles 51 through fasteners; among them, Figure 9 Only the first baffle 51 is shown.

[0092] Reference Figure 8 In some embodiments, a plurality of soft scraping teeth cooperating with the filter screen are connected along the edge of the spiral plate 211. The plurality of soft scraping teeth are arranged at intervals along the spiral extension direction of the spiral plate. The rotation of the screw push rod 21 drives the spiral plate 211 and the soft scraping teeth 212 to rotate together. During the rotation, the soft scraping teeth 212 contact the filter screen 31 and scrape off the cat feces fragments and other impurities attached to the filter screen 31, preventing these fragments from blocking the filter screen 31.

[0093] The soft scraping teeth can be made of TPR or silicone.

[0094] In some embodiments, the bottom wall of the receiving tank 11 forms an inclined arc transition surface from the side wall of the receiving tank 11 to the conveying tank 113, and the conveying tank 113 is located at the lowest part of the receiving tank 11.
