[0031] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0032] In this specification, a smart cat litter box is provided. This specification also relates to a cleaning control method of the smart cat litter box, which is described in detail one by one in the following embodiments.

[0033] The present specification provides an embodiment of a smart cat litter box. Figure 1 FIG. 1 shows a block diagram of a smart cat litter box provided by an embodiment of the present specification. Figure 1 As shown, the smart cat litter box includes a cat litter box inner bin 1 and a cat litter scoop 2 which can rotate respectively, and the cat litter scoop 2 can rotate in the inner bin space formed by the cat litter box inner bin 1, and the cat litter scoop 2 includes a cat litter scoop body 3 and a water spraying member 4. The cat litter box inner bin 1 is an arc-shaped semicircle with a U-shaped cross section.

[0034] Specifically, the cat litter scoop is coaxially arranged with the inner bin of the cat litter box and can rotate relatively, and is used to remove dirt in the inner bin of the cat litter box through the cat litter scoop body, and to clean the cat litter scoop and the inner bin of the cat litter box with water sprayed by the water spraying part.

[0035] It should be noted that the smart cat litter box at least includes a cat litter scoop and a cat litter box inner bin that can rotate separately. The cat litter box inner bin is used to place cat litter, and the cat can enter the cat litter box inner bin and defecate on the cat litter; the cat litter scoop is used to rotate in the cat litter box inner bin to remove dirt in the cat litter box inner bin, or to scrape and clean the cat litter box inner bin. After the cat defecates, it is necessary to promptly remove the dirt produced by the cat's excretion on the cat litter, and regularly clean the cat litter scoop and the cat litter box inner bin, so when it is necessary to remove dirt or need to be washed with water, a cleaning instruction can be triggered.

[0036] In an optional implementation of this specification, Figure 2 FIG. 1 is a schematic diagram of the structure of a cat litter scoop body in an intelligent cat litter box provided by an embodiment of the present specification. Figure 2 As shown, the cat litter scoop body 3 includes a first pivot arm 31 and a second pivot arm 32, and an arc frame 33 connected between the first and second pivot arms, the arc frame 33 extends and forms a plurality of ribs 34 arranged at intervals, and the water spraying member 4 is arranged near the root of the ribs 34. In other words, the cat litter scoop body 3 may include an arc frame 33, and ribs are formed by extending from the arc frame. Specifically, the arc frame is adapted to the inner surface of the inner bin of the cat litter box, and the intervals between the plurality of ribs extending from the arc frame are used to filter out clean cat litter.

[0037] It should be noted that the cat litter scoop body includes a first pivot arm and a second pivot arm, an arc-shaped frame is connected between the first and second pivot arms, and a plurality of ribs arranged at intervals are extended from the arc-shaped frame. The cat litter scoop body is a guardrail-like structure. Dirt is blocked by the ribs, and clean cat litter can be separated from the intervals between adjacent ribs and remain in the cat litter box for continued use, thereby achieving separation of clean cat litter and saving cat litter.

[0038] In an optional implementation of this specification, Figure 2 As shown, the cat litter scoop 2 has a first filter area composed of a plurality of ribs 34 and second filter areas located on both sides of the first filter area. The interval between adjacent ribs 34 in the first filter area is smaller than the interval between adjacent ribs 34 in the second filter area.

[0039] In actual implementation, the area formed by the plurality of ribs in the cat litter scoop is divided into two filtering areas, the first filtering area is located in the middle, and the second filtering area is located on both sides, and the interval between adjacent ribs in the first filtering area is smaller than the interval between adjacent ribs in the second filtering area. In other words, the gap between the ribs on both sides of the cat litter scoop body is large, and the gap between the ribs in the middle is small.

[0040] It should be noted that, because during the process of shoveling feces, the accumulated cat litter scooped up by the cat litter scoop will flow out to both sides of the cat litter scoop, the gaps between the ribs on both sides are set wider to facilitate the clean cat litter to leak out of the cat litter scoop, while the gaps between the middle ribs are set smaller to ensure that the clumped dirt will not leak out when scooped up.

[0041] In an optional embodiment of the present specification, the rib 34 extends along the rotation direction of the cat litter scoop 2, and the width of the two ends of the extension gradually shrinks. The rotation direction is defined as the front-to-back direction, and the width of the two ends of the rib 34 extending along the front-to-back direction gradually shrinks. Figure 3 As shown, the rib 34 is constructed to be wide in the middle and thin at both ends. Figure 3 It is a schematic diagram of the structure of ribs in a smart cat litter box provided in one embodiment of the present specification.

[0042] It should be noted that the width in the middle of the rib can reduce the gap between adjacent ribs, thereby better blocking the scooped dirt, while the thin structure at both ends can facilitate the clean cat litter to flow out and remain in the inner bin of the cat litter box, so as to filter the clean cat litter.

[0043] In an optional implementation of this specification, Figure 4a This is a schematic diagram of a water flow structure of a water spraying member in an intelligent cat litter box provided in one embodiment of the present specification. Figure 4b FIG. 1 is a partially enlarged schematic diagram of a water spray hole in a water spray member provided in one embodiment of the present specification, such as Figure 4a and Figure 4b As shown, the water spraying member 4 has a main body 41, the main body 41 is provided with a plurality of water spraying holes 42, the main body 41 is provided with a water inlet 43 and a multi-stage water diversion channel 44 connected between the water inlet 43 and the plurality of water spraying holes 42, and the water spraying holes 42 include a first water spraying hole 421 arranged corresponding to the rib 34. The main body 41 extends between the first and second pivot arms 31, 32.

[0044] In actual implementation, the water flow structure of the water spraying member 4 is that water enters from the water inlet 43 set at the top, passes through the internal multi-stage water diversion channel 44, and flows out from the water spraying hole 42 connected to the multi-stage water diversion channel 44. The multi-stage water diversion channel 44 adopts a layered partition structure, which divides the incoming single stream of water into multiple streams, and evenly flows out from each water spraying hole 42 connected to the multi-stage water diversion channel 44. In an optional embodiment of the present specification, as Figure 4a and Figure 4b As shown, the water spray hole 42 includes a plurality of first water spray holes 421, each of which is disposed near the corresponding rib 34. Specifically, the first water spray hole 421 is disposed at the bottom of the main body 41, and the first water spray hole 421 is disposed corresponding to the rib 34. Water can be sprayed toward the rib 34 through the first water spray hole 421 to achieve fixed-point water spray cleaning of the rib 34.

[0045] One rib may correspond to at least one first water spray hole. In specific implementation, a first water spray hole is set on one side of a rib, that is, one first water spray hole is set on one side of each rib, such as being set on the left or right side of the rib; or, first water spray holes may be set on both sides of the rib to achieve full cleaning.

[0046] In actual implementation, Figure 2 , Figure 4a and Figure 4b As shown, water flows through a water pipe through the rotating shaft of the first pivot arm 31 and is connected to the top water inlet 43 of the water spraying member 4, and passes through the water pipe as shown in FIG. Figure 2 , Figure 4a and Figure 4bThe multi-stage water distribution channel 44 shown in the figure, water flows out from the first water spray hole 421 at the bottom of the main body 41. The first water spray hole 421 is located above the root of the rib 34, and the first water spray hole 421 is evenly distributed on both sides of the root of each rib 34 of the cat litter scoop body 3. The water flowing out of the first water spray hole 421 will flow along the rib 34 into the inner bin 1 of the cat litter box. In the process of flowing down along the rib 34, the water will also clean the dirt that may be attached to the rib 34. Figure 5 shown.

[0047] In an optional implementation of this specification, Figure 6 As shown, a receiving chamber 35 is recessed on the top of the cat litter scoop body 3, and the receiving chamber 35 extends between the first and second pivot arms and extends downward to the top of the rib 34. The water spraying member 4 is embedded in the receiving chamber 35 and is located above the rib 34. The bottom of the receiving chamber 35 has an opening (not shown) corresponding to the first water spraying hole 421, so that the first water spraying hole 421 can spray cleaning liquid to the rib 34. The first water spraying hole 421 is arranged on both sides of the root of each rib 34, and the first water spraying hole 421 is arranged close to the side edge of the root of the rib 34. In this embodiment, the first water spraying hole 421 is formed by vertically penetrating the bottom channel of the multi-stage water diversion channel 44 downward.

[0048] It should be noted that the water spraying member 4 is installed inside the cat litter scoop body 3, and the components are as follows: Figure 6 As shown, the water spraying member 4 is received in the receiving cavity 35 of the cat litter scoop body 3, and the water spraying member 4 is fixed to the cat litter scoop body 3 by screws 5. A cover plate 36 is provided on the top of the receiving cavity 35 to cover the water spraying member 4. After the above parts are assembled, they can be installed in the inner bin 1 of the cat litter box. The assembly relationship diagram is shown in FIG. Figure 7 shown.

[0049] In an optional embodiment, the water spraying member 4 is fixedly mounted on the outer surface of the cat litter scoop body 3 ; the water spraying member 4 includes a first water spraying hole 421 , and the first water spraying hole 421 is located outside the root of the rib 34 .

[0050] Specifically, the main body of the water spray component 4 is extended to form a fixing frame, and the fixing frame is provided with a through fixing hole, which is cooperated with the fixing hole by the screw 5 to fix the water spray component 4 on the outer surface of the cat litter shovel body 3. The first water spray hole 421 (that is, the vertical water spray hole in the water spray hole 43 connected to the multi-stage water diversion channel) is located outside the root of the rib 34. Water can be sprayed onto the rib 34 through the first water spray hole 421 to achieve fixed-point water spraying and cleaning of the rib 34. The first water spray hole 421 is arranged at a certain distance from the rib 34.

[0051] It should be noted that the water spraying member 4 is mounted on the outer surface of the cat litter scoop body 3. Figure 8As shown, the main body of the water spraying member 4 is fixed to the cat litter scoop body 3 by screws 5 and the fixing holes on the fixing frame. The above method makes the water spraying member 4 located on the outer side wall of the cat litter scoop body 3. After the above parts are assembled, the assembly relationship diagram is as shown in FIG. Fig. 9 As shown, the water spraying member 4 is arranged on one side of the cat litter scoop 2 in the rotating direction of scooping feces.

[0052] In actual implementation, the water flowing out from the first water spray hole 421 will be sprayed to the position above the root of the rib, that is, the outer surface above the root of the rib of the cat litter scoop body. The sprayed water flows down along the front end outer wall plane of the cat litter scoop body, and flows toward the rib along the root of the rib connected to the wall of the cat litter scoop body, so that the water flows along the cat litter scoop body into the inner bin, and each rib is also cleaned by the water flow. Fig.10 shown.

[0053] In the embodiment of this specification, two installation methods of the water spraying member 4 are provided. One installation scheme is that the water spraying member 4 is installed inside the cat litter scoop body 3, and the water flows out from the water spraying hole 42 through the multi-stage water distribution channel 44 inside the water spraying member 4, and flows into the inner bin 1 of the cat litter basin along the ribs 34 of the cat litter scoop body 3; the other installation method is that the water spraying member 4 is installed on the outer wall of the cat litter scoop body 3 by screw installation, and the water flows out from the water spraying hole 42 through the multi-stage water distribution channel 44 inside the water spraying member 4, and flows into the inner bin along the outer wall of the cat litter scoop body 3. The installation method of the water spraying member 4 is flexible and can adapt to different usage scenarios.

[0054] For the solution in which the water spray component 4 is installed outside the cat litter scoop body 3, a guide plate 45 extending downwardly and obliquely toward the ribs 34 is provided at the bottom of the main body of the water spray component 4. The end of the guide plate 45 is located above the root of the ribs 34 and is spaced a certain distance from the outer surface of the cat litter scoop body 3. The guide plate 45 guides the water flowing out of the first water spray hole 421 to the outer surface of the cat litter scoop body 3. A water storage tank is formed below the first water spray hole 421 by the guide plate 45, so that water flows out through the long strip gap formed between the guide plate 45 and the outer surface of the cat litter scoop body 3. Although the solution is to discharge water through the long strip gap, the water flowing toward the wall of the cat litter scoop body 3 will eventually converge on the ribs 34 located below the wall, and flow into the inner bin 1 of the cat litter basin through the ribs 34, while also achieving the cleaning of dirt on the ribs 34, as described above. Fig.10 shown.

[0055] In actual implementation, the length of the guide plate is at least equal to the overall width of the ribs on the cat litter scoop body, so that the length of the long strip gap formed is at least equal to the overall width of the multiple ribs on the cat litter scoop body, ensuring that the water flow can flow to each rib and avoiding the existence of cleaning dead corners.

[0056] In an optional implementation of this embodiment, Figure 4a and Figure 5As shown, the main body of the water spraying member 4 is provided with a second water spraying hole 422 at its end, and the second water spraying hole 422 is connected to the multi-stage water diversion channel 44. The second water spraying hole 422 and the first water spraying hole 421 have different water spraying directions. The second water spraying hole 421 sprays liquid toward the side wall of the inner bin 1 of the cat litter box, while the first water spraying hole 421 sprays liquid toward the arc-shaped inner bottom surface of the inner bin 1 of the cat litter box.

[0057] Specifically, the second water spray hole can be a water spray hole that extends laterally through the end of the main body and is connected to the multi-stage water diversion channel. The second water spray hole is arranged toward the side wall of the inner bin of the cat litter box and is used to spray water on the side wall of the inner bin of the cat litter box to clean the side wall of the inner bin of the cat litter box.

[0058] It should be noted that, no matter the water spraying member is installed inside or outside the cat litter scoop body, the water spraying member may include a first water spraying hole and a second water spraying hole with different water spraying directions, and water is sprayed toward the side wall of the inner bin of the cat litter box through the second water spraying hole to clean the side wall of the inner bin of the cat litter box. Figure 5 In the embodiment shown, the water spraying member 4 is accommodated in the receiving chamber 35 of the cat litter shovel body 3, and the second water spraying holes 422 are arranged at both ends of the bottom channel in the multi-stage water diversion channel 44. The two side walls of the receiving chamber 35 are provided with openings corresponding to the second water spraying holes 422, so that the second water spraying holes 422 spray toward the side walls of the inner bin 1 of the cat litter box.

[0059] In the embodiments of the present specification, second water spray holes can be provided at both ends of the main body of the water spray component to spray water on the side walls of the inner bin of the cat litter box. While the first water spray holes spray water on the ribs of the cat litter shovel body, the second water spray holes spray water on the side walls of the inner bin of the cat litter box, thereby improving the cleaning efficiency and ensuring that the smart cat litter box is fully cleaned.

[0060] In an optional implementation of this embodiment, Figure 6-Figure 9 As shown, the cat litter scoop body 3 has an arc-shaped frame 33 and a soft rubber scraper strip 6 arranged along the arc-shaped frame 33 , and the soft rubber scraper strip 6 is in interference contact with the inner surface of the inner bin 1 of the cat litter box.

[0061] Specifically, the cat litter scoop 2 also includes a soft rubber scraper strip 6, which is fixed on the arc-shaped frame 33 by means of rubber coating. When in use, the soft rubber scraper strip 6 is in interference contact with the inner surface of the inner bin 1 of the cat litter box, thereby achieving the cleaning of the inner bin 1 of the cat litter box after water is passed through. The soft rubber scraper strip 6 has a protrusion 61, and the protrusion 61 is in interference fit with the inner bin 1 of the cat litter box to scrape the dirt in the inner bin 1 of the cat litter box. In specific implementation, the protruding length of the protrusion 61, that is, the interference amount, can be set based on actual needs. The larger the interference amount, the greater the rotational resistance of the cat litter scoop 2 and the inner bin 1 of the cat litter box, but the scraping is relatively clean. Excessive interference may cause the cat litter scoop 2 to be unable to enter the inner bin 1 of the cat litter box. Therefore, in actual applications, the interference amount is generally set to be smaller, such as an interference amount of 0.5mm. Of course, in actual implementation, it can also be set to other values, such as an interference amount of 0.3mm, 0.6mm, etc. For example, Fig.11 As shown, the length of the protruding portion 61 of the soft rubber scraper 6 provided on the cat litter scoop body 3 is 0.5 mm (i.e., the interference is 0.5 mm), and the soft rubber scraper 6 is interference fit with the inner bin 1 of the cat litter box, and is in a fitted state when in actual rotation. In actual implementation, whether the water spraying part is installed inside or outside the cat litter scoop body, the soft rubber scraper can be fixed on the outside of the cat litter scoop body by means of rubber coating, such as Figure 6-Figure 9 shown.

[0062] It should be noted that in order to scrape and clean the inner bin of the cat litter box, the cat litter scoop needs to be in interference contact with the inner surface of the inner bin of the cat litter box, so that the cat litter scoop or the inner bin of the cat litter box can be rotated to scrape and clean the dirt stuck in the inner bin of the cat litter box. The soft rubber scraping strip is used to scrape and clean the inner bin of the cat litter box, thereby avoiding damage to the inner bin of the cat litter box. The soft rubber scraping strip is fixed on the outside of the cat litter scoop body by rubber coating, so that the soft rubber scraping strip is used to scrape and clean the inner bin of the cat litter box.

[0063] In an optional implementation of this embodiment, the arc-shaped frame 33 is convexly provided on one side of its bottom edge toward the rotation direction of the cat litter scoop 2 to form a hard shovel edge, see Fig.11 and Fig.12 As shown, the outer edge of the hard shovel edge is arranged close to the inner surface of the inner bin 1 of the cat litter box but not in contact with it, so as to prevent the hard shovel edge from scratching the inner bin, and the inner edge of the hard shovel edge is in an arc shape, so as to facilitate the hard shovel edge to remove the dirt adhering to the inner bin, and a soft rubber scraper strip 6 is arranged on the other side of the arc frame of the cat litter shovel body 3, that is, the soft rubber scraper strip 6 is arranged on the other side of the arc frame relative to the hard shovel edge. In this way, by using the two sides of the bottom edge of the arc frame of the cat litter shovel, under the scraping and washing rotation, the hard shovel edge first scrapes off the hard-to-clean solid or sticky dirt adhering to the inner bin of the cat litter box, and the soft rubber scraper strip then contacts the inner bin to remove the residual dirt, so as to avoid residual dirt.

[0064] In an optional implementation of the present embodiment, the bottom edge of the arc-shaped frame 33 included in the cat litter scoop body 3 and the inner bin 1 of the cat litter box have a set arc-shaped scooping angle.

[0065] It should be noted that the hard shovel edge forms a shovel angle relative to the inner bin of the cat litter box. Fig.12 As shown, there is a certain shoveling angle between the circumferential tangent of the inner bin 1 of the cat litter box and the cat litter shovel body 3, and the shoveling angle is an acute angle of 53°. When the cat litter shovel body scoops up the dirt at the bottom of the inner bin, the hard shoveling edge as an acute angle can effectively remove the adhered dirt.

[0066] See also Fig.13 As shown, the bottom edge of the arc frame 33 is arc-shaped, and the gap between the arc frame 33 and the inner bin 1 of the cat litter box is small at the front end and large at the rear end. This design can effectively reduce the crushing caused by cat litter entering the gap between the bottom of the cat litter scoop body and the inner bin of the cat litter scoop, and at the same time reduce the friction between the cat litter scoop body and the inner bin of the cat litter scoop.

[0067] The embodiment of the present specification provides a smart cat litter box, which includes a cat litter box inner bin that can be rotated separately and a cat litter scoop located in the cat litter box inner bin, the cat litter scoop and the cat litter box inner bin coaxially rotate relative to each other, the cat litter scoop includes a cat litter scoop body and a water spraying member fixed to the cat litter scoop body, and through the corresponding cleaning mode, the cat litter scoop and / or the cat litter box inner bin can be controlled to rotate, and through the rotation of the cat litter scoop and / or the cat litter box inner bin, the dirt in the cat litter box inner bin can be removed, and / or the cat litter scoop and the cat litter box inner bin can be cleaned by water flow sprayed by the water spraying member. That is, the smart cat litter box combines the functions of automatically removing dirt and automatically cleaning with water, and the functions of the cat litter box are more diverse and more concentrated, and the dirt in the cat litter box inner bin can be automatically scraped off, and the water flow sprayed by the water spraying member can automatically clean the cat litter scoop and the cat litter box inner bin, automatically and efficiently cleaning the cat litter box without user intervention, freeing the user's hands, and allowing users to keep pets cleaner.

[0068] Next, combining the above Figure 1-Figure 13 The structure of the smart cat litter box shown in the figure is used to discuss in detail the cleaning control method of the smart cat litter box:

[0069] For Dirt Removal Mode:

[0070] After the smart cat litter box is powered on, the system controls the entire cat litter shovel to rotate in a circle under the action of the motor; when the cat litter shovel body passes through the cat litter, it will scoop up the urine and feces in the cat litter, and separate the urine and feces from the clean cat litter, leaving the clean cat litter for continued use, and pouring the urine and feces into the feces collection bin. In addition, the bottom of the cat litter shovel body has a 53° scooping angle, which can effectively scoop up the urine and feces stuck in the cat litter box. Among them, the urine and feces are the above-mentioned dirt, and the feces collection bin is the above-mentioned dirt collection bin.

[0071] For water cleaning mode:

[0072] Through system control, under the action of the motor, after all the waste litter in the inner bin of the cat litter box is poured into the feces collecting bin, the cat litter shovel body is rotated to a vertical downward position by the motor, the water adding device is turned on, and the water flows out evenly from the vertical water spray hole, along the rib surface of the cat litter shovel body (the solution in which the water spray part is installed inside the cat litter shovel body) or the outer surface of the cat litter shovel body (the solution in which the water spray part is installed outside the cat litter shovel body) to flow down, and the local easily dirty surface of the cat litter shovel body is cleaned. After the water cleans the cat litter shovel body, it flows along the rib surface of the cat litter shovel body to the inner bin of the cat litter box. After the water is passed, the inner bin of the cat litter scoop rotates at a certain angle, so that the inner bin of the cat litter box and the cat litter scoop rotate coaxially relative to each other. The soft rubber scraper of the cat litter scoop fits with the inner bin of the cat litter box. During the relative rotation, the soft rubber scraper scrapes and washes the small urine particles remaining on the inner bin of the cat litter box, and cleans the inner bin of the cat litter box. Then the inner bin of the cat litter box rotates to a certain angle to pour the sewage into the sewage tank. Finally, the inner bin of the cat litter box is fixed, and the cat litter scoop rotates 2 circles, so that the soft rubber scraper scrapes the water stains remaining on the surface of the inner bin of the cat litter box into the sewage tank.

[0073] The embodiments of the present specification provide a smart cat litter box, which combines the functions of automatic removal of dirt and automatic water cleaning. The functions of the cat litter box are more diversified and more concentrated. The dirt in the inner bin of the cat litter box can be automatically scraped off, and the water flow sprayed by the water spray part can automatically clean the cat litter scoop and the inner bin of the cat litter box. The cat litter box is automatically and efficiently cleaned without user intervention, freeing the user's hands and allowing the user to keep pets cleaner.

[0074] See also Fig.14 , Fig.14 FIG. 1 shows a structural block diagram of a cat litter scoop provided by an embodiment of the present specification. Fig.14 As shown, the cat litter scoop 2 includes a cat litter scoop body 3 and a water spray member 4 fixed to the cat litter scoop body 3. The cat litter scoop body 3 includes a first pivot arm 31 and a second pivot arm 32, and an arc frame 33 connected between the first and second pivot arms. A plurality of ribs 34 extending from the arc frame 33 and arranged at intervals are formed. The water spray member 4 is arranged near the root of the rib 34.

[0075] It should be noted that the cat litter scoop can rotate coaxially with the inner bin of the cat litter box.

[0076] In an optional implementation of this specification, Fig.14 As shown, the cat litter scoop 2 has a first filter area composed of a plurality of ribs 34 and second filter areas located on both sides of the first filter area. The interval between adjacent ribs 34 in the first filter area is smaller than the interval between adjacent ribs 34 in the second filter area.

[0077] In an optional embodiment of the present specification, the ribs 34 extend along the rotation direction of the cat litter scoop 2 and the width of the two ends of the extension gradually shrinks.

[0078] In an optional implementation of this embodiment, Fig.14 As shown, the cat litter scoop body 3 has an arc-shaped frame 33 and a soft rubber scraper strip 6 arranged along the arc-shaped frame, and the soft rubber scraper strip 6 is in interference contact with the inner surface of the inner bin 1 of the cat litter box.

[0079] In an optional implementation of this embodiment, the arc-shaped frame 33 is convexly provided on one side of its bottom edge toward the rotation direction of the cat litter scoop 2 to form a hard shoveling edge, and the soft rubber scraper strip 6 is arranged on the other side of the arc-shaped frame 33 opposite to the hard shoveling edge.

[0080] In an optional implementation of the present embodiment, the bottom edge of the arc-shaped frame 33 included in the cat litter scoop body 3 and the inner bin 1 of the cat litter box have a set arc-shaped scooping angle.

[0081] In an optional implementation of the present embodiment, the bottom edge of the arc-shaped frame 33 is arc-shaped, and the gap between the arc-shaped frame 33 and the inner bin 1 of the cat litter box is small at the front end and large at the rear end.

[0082] The embodiments of the present specification provide a cat litter scoop, which combines the functions of automatic removal of dirt and automatic water cleaning. The functions of the cat litter scoop are more diversified and more concentrated. It can automatically scrape dirt from the inner bin of the cat litter box, and the water flow sprayed by the water spray part can automatically clean the cat litter scoop and the inner bin of the cat litter box through water. The cat litter box is automatically and efficiently cleaned without the need for user intervention, freeing the user's hands and allowing the user to keep pets cleaner.

[0083] The above is a schematic scheme of a cat litter scoop of this embodiment. It should be noted that the details of the cat litter scoop can be found in the aforementioned Figure 1-Figure 13 The smart cat litter box shown in the figure will not be described in detail in this specification.

[0084] See also Fig.15 , Fig.15 is a flow chart of a cleaning control method of an intelligent cat litter box provided according to an embodiment of this specification, which is applied to the above Figure 1-Figure 13The smart cat litter box shown in the figure comprises a litter box inner bin and a litter scoop which can rotate respectively. The litter scoop can rotate in the inner bin space formed by the inner bin of the litter box. The litter scoop comprises a litter scoop body and a water spraying part. Specifically, the following steps 1502-1506 are included.

[0085] Step 1502: Receive a cleaning instruction for the smart cat litter box, wherein the cleaning instruction carries a cleaning mode.

[0086] Specifically, when the cleaning instruction is triggered, a cleaning mode for cleaning the smart cat litter box can be carried out, and the cleaning mode at least includes a dirt removal mode and a water cleaning mode, wherein the dirt refers to feces and urine balls produced by cat excretion.

[0087] It should be noted that the smart cat litter box at least includes a rotatable inner bin of the cat litter box and a cat litter scoop located in the inner bin of the cat litter box, the cat litter scoop rotates coaxially with the inner bin of the cat litter box, the cat litter scoop includes a cat litter scoop body and a water spraying part fixed to the cat litter scoop body, the inner bin of the cat litter box is used to place cat litter, and the cat can enter the inner bin of the cat litter box and defecate on the cat litter. After the cat defecates, it is necessary to promptly remove the dirt produced by the cat's excretion on the cat litter, and regularly clean the cat litter scoop and the inner bin of the cat litter box, so when it is necessary to remove dirt or need to be cleaned with water, a cleaning instruction can be triggered.

[0088] In specific implementation, the left side of the cat litter box can be set as the cat's entrance, that is, the opening of the smart cat litter box is on the left. When dumping dirt or sewage in the cat litter box, turn it to the left. The sewage collection bin, sewage tank, etc. can be set on the left side of the cat litter box.

[0089] In actual applications, a cleaning control can be provided on the smart cat litter box. The cleaning control can be an actual physical button or a click position in a touch display screen. The user can trigger the cleaning control on the smart cat litter box to trigger the cleaning instruction and carry the corresponding cleaning mode in the cleaning instruction.

[0090] In another implementation, an automatic cleaning logic may be pre-configured in the smart litter box. The automatic cleaning logic may automatically trigger a cleaning instruction for a corresponding cleaning mode when set conditions are met. For example, the automatic cleaning logic may be: detecting that a cat enters the smart litter box for a set period of time and then leaves the smart litter box, triggering a cleaning instruction for a dirt removal mode; and triggering a cleaning instruction for a water cleaning mode once every set period of time.

[0091] Of course, other automatic cleaning logics may be configured based on actual scenario requirements, and the embodiments of this specification do not limit this.

[0092] Step 1504: Determine a corresponding cleaning control strategy according to the cleaning mode.

[0093] It should be noted that different cleaning modes may be configured with different cleaning control strategies, which refers to a rotation control strategy for controlling the cat litter scoop and / or the inner bin of the cat litter box to rotate to achieve the cleaning of the corresponding mode.

[0094] In actual applications, the cleaning mode may include a dirt removal mode and a water cleaning mode. For the dirt removal mode, the cleaning control strategy can be pre-configured to sequentially execute the operations of dumping cat litter, passing water, and stopping the water flow; for the dirt removal mode, the cleaning control strategy can be pre-configured to control the cat litter shovel to rotate in a circle.

[0095] Of course, the above are only examples for the dirt removal mode and the water cleaning mode. In actual implementation, the corresponding cleaning control strategy can also be configured according to the specific scenario requirements. For example, for the dirt removal mode, the cleaning control strategy can be pre-configured to sequentially perform operations such as dumping cat litter, passing water, stopping water flow, scraping and washing; for the dirt removal mode, the cleaning control strategy can also be pre-configured to control the cat litter shovel and the cat litter bin to rotate in a circle, etc. The embodiments of this specification do not limit this.

[0096] In specific implementation, different cleaning modes are each configured with a corresponding cleaning control strategy. When a cleaning instruction for the smart cat litter box is received, the cleaning instruction can be parsed to obtain the cleaning mode, and then the corresponding cleaning control strategy can be found based on the cleaning mode, so that the cat litter shovel and / or cat litter bin can be controlled to rotate based on the cleaning control strategy to achieve cleaning in the corresponding cleaning mode.

[0097] Step 1506: According to the cleaning control strategy, the cat litter scoop and / or the inner bin of the cat litter box are controlled to rotate, and dirt in the inner bin of the cat litter box is removed by rotation, and / or the cat litter scoop and the inner bin of the cat litter box are cleaned by water sprayed by a water sprayer.

[0098] It should be noted that the cleaning control strategy can indicate the rotation logic of the cat litter scoop and / or the inner bin of the cat litter box in the corresponding cleaning mode. Therefore, the cat litter scoop and / or the inner bin of the cat litter box can be controlled to rotate according to the cleaning control strategy. The rotation of the cat litter scoop and / or the inner bin of the cat litter box can be used to clear the dirt in the inner bin of the cat litter box, or the rotation of the cat litter scoop and / or the inner bin of the cat litter box combined with the water flow sprayed by the water spray part can be used to clean the cat litter scoop and the inner bin of the cat litter box.

[0099] In an optional implementation of this embodiment, the cleaning mode is a water cleaning mode, and the water cleaning mode includes:

[0100] The water spraying part passes water, and water is sprayed toward the cat litter scoop through the water spraying part;

[0101] Stop passing water to the water spraying part, control the cat litter scoop and the inner bin of the cat litter box to rotate relative to each other, and scrape and clean the inner bin of the cat litter box.

[0102] It should be noted that the cleaning mode is a water-through cleaning mode, which means that water needs to be added to the smart cat litter box for cleaning, so all the waste litter in the inner bin of the cat litter box needs to be poured out first. In specific implementation, the inner bin of the cat litter box can be controlled to rotate in a circle to pour the waste litter in the inner bin of the cat litter box into the dirt collection bin, which refers to a collection device arranged under the inner bin of the cat litter box. The dirt collection bin can be used to collect the dirt removed or the waste litter discharged. Among them, circular rotation refers to the inner bin of the cat litter box rotating around a fixed axis at a set angle, and its rotation trajectory is a part of the circumference.

[0103] In actual implementation, after pouring the waste litter in the inner bin of the cat litter box into the waste collection bin, the water adding device can be turned on to pass water to the water spraying part, and the water flow will be sprayed to the cat litter scoop through the water spraying part. The sprayed water will flow to the cat litter scoop to clean the local dirty surface of the cat litter scoop, and then flow into the inner bin of the cat litter box. After the water adding and cleaning is set for a certain period of time, the water adding device can be controlled to close, the water flow is stopped, and the cat litter scoop and the inner bin of the cat litter box are controlled to rotate relative to each other to scrape and clean the inner bin of the cat litter box.

[0104] The set time is generally set to be relatively short to prevent excessive water from accumulating in the litter box, which may cause sewage to overflow during the scraping process. However, the set time cannot be set too short, which may result in too little water flowing into the litter box, making it impossible to clean the litter scoop or to fully soak the litter box. In practice, the set time can be set based on the size of the litter scoop, the litter box, the water flow rate, etc.

[0105] In the embodiments of the present specification, the water spray component and the cat litter scoop are arranged correspondingly, so that the water sprayed by the water spray component flows to the cat litter scoop, passes through the cat litter scoop and then flows into the inner compartment of the cat litter box. Thereafter, the cat litter scoop and the inner compartment of the cat litter box are controlled to rotate relative to each other, thereby achieving automatic cleaning of the cat litter scoop and the inner compartment of the cat litter box at the same time, ensuring the cleanliness of the smart cat litter box and improving the cleaning efficiency.

[0106] In an optional implementation manner of this embodiment, before the water spraying member passes water, the method further includes:

[0107] Controlling the inner bin of the cat litter box to rotate from an initial position to a first position, wherein the first position is a position for pouring waste litter in the inner bin of the cat litter box into a waste collection bin;

[0108] After the set time, the inner compartment of the cat litter box is controlled to return from the first position to the initial position.

[0109] Specifically, the initial position is the position of the inner bin of the cat litter box when it is not rotated, that is, the initial position is the use position of the inner bin of the cat litter box, which is convenient for the cat to enter and exit, so as to facilitate the cat to defecate in the inner bin of the cat litter box. As an example, the inner bin of the cat litter box is a smooth semi-rotating body that can rotate axially and perform circular rotation. The initial position is that the inner bin of the cat litter box opens upward, and the direction of the opening of the inner bin of the cat litter box is parallel to the horizontal direction.

[0110] In addition, the first position is a position at which the waste litter in the inner bin of the cat litter box can be poured into the waste collecting bin. The first position is related to the position of the waste collecting bin. From the above, it can be seen that assuming that the waste collecting bin is on the left side of the inner bin of the cat litter box, the first position can be a position rotated to the right at a set angle so that the opening of the inner bin of the cat litter box is tilted to the left, and the waste litter is poured into the waste collecting bin from the left.

[0111] In actual implementation, the set time length is the length of time the inner bin of the cat litter box stays in the first position, which is generally set relatively small so that all the waste litter in the inner bin of the cat litter box can be poured into the waste collection bin.

[0112] In the embodiment of the present specification, the inner bin of the cat litter box can be controlled to rotate from the initial position to the first position, and after staying for a set period of time, the inner bin of the cat litter box can be controlled to return from the first position to the initial position, thereby automatically dumping the waste litter in the inner bin of the cat litter box for subsequent cleaning steps. There is no need for the user to manually dump the waste litter, freeing the user's hands and achieving fully automatic cleaning.

[0113] In an optional implementation manner of this embodiment, before the water spraying member passes water, the method further includes:

[0114] The cat litter scoop is controlled to rotate to a vertical downward state, and the cat litter scoop is cleaned by water flow sprayed by the water spraying part, and then the water flow flows into the inner bin of the cat litter box.

[0115] It should be noted that if there is an angle between the cat litter scoop and the direction of gravity, that is, the cat litter scoop is set at an angle or horizontally, the water sprayed on the cat litter scoop will directly flow into the inner bin of the cat litter box due to the effect of gravity, and cannot flow through the entire surface of the cat litter scoop, and cannot achieve complete cleaning of the cat litter scoop. Therefore, before turning on the water adding device and spraying water on the cat litter scoop, the cat litter scoop can be controlled to rotate to a vertical downward state. At this time, the water sprayed by the water spraying part can flow down along the surface of the cat litter scoop, clean the complete surface of the cat litter scoop, and the water after cleaning the cat litter scoop will flow into the inner bin of the cat litter box. In this way, while cleaning the inner bin of the cat litter box, it is ensured that the cat litter scoop can be fully cleaned, and the cleaning of the cat litter scoop and the inner bin of the cat litter box can be achieved at the same time, ensuring the cleanliness of the smart cat litter box and improving the cleaning efficiency.

[0116] In an optional implementation of this embodiment, the cat litter scoop includes a cat litter scoop body and a soft rubber scraper, the soft rubber scraper is arranged on the arc-shaped frame of the cat litter scoop body, and the soft rubber scraper abuts against the inner bin of the cat litter box; at this time, the cat litter scoop and the inner bin of the cat litter box are controlled to rotate relative to each other to scrape and clean the inner bin of the cat litter box, including:

[0117] The inner bin of the cat litter box is controlled to rotate at least once along a first set direction, and the inner bin of the cat litter box is scraped and cleaned by the soft rubber scraping strip.

[0118] It should be noted that in order to scrape and clean the inner bin of the cat litter box, the cat litter scoop needs to abut against the inner bin of the cat litter box, so as to scrape and clean the dirt stuck in the inner bin of the cat litter box by rotating the cat litter scoop or rotating the inner bin of the cat litter box. When using the cat litter scoop to scrape and clean the inner bin of the cat litter box, in order to avoid damaging the inner bin of the cat litter box, a soft rubber scraping strip is fixed on the outside of the cat litter scoop body by a rubber coating method, so as to scrape and clean the inner bin of the cat litter box by the soft rubber scraping strip.

[0119] In specific implementation, the two sides of the bottom edge of the cat litter shovel can be reused. One side is set as a hard shovel angle to remove dirt, and the other side is set as a soft rubber scraper strip through rubber coating to protect the surface of the inner bin of the cat litter box.

[0120] In practical applications, the inner bin of the cat litter box can be controlled to rotate at least once along a first set direction, and the inner bin of the cat litter box can be scraped and cleaned by the soft rubber scraper strip. In one implementation, the inner bin of the cat litter box can be controlled to rotate at least once along a first set direction so that the water in the inner bin of the cat litter box can fully soak the surface of the inner bin of the cat litter box, and then the inner bin of the cat litter box can be controlled to be fixed, and the cat litter shovel can be controlled to rotate along the inner bin of the cat litter box, so that the cat litter shovel and the inner bin of the cat litter box can rotate relative to each other, and the inner bin of the cat litter box can be scraped and cleaned by the soft rubber scraping strips provided by the cat litter shovel; in another implementation, the inner bin of the cat litter box can be controlled to rotate at least once along a first set direction so that the water in the inner bin of the cat litter box can fully soak the surface of the inner bin of the cat litter box, and then the cat litter shovel can be controlled to rotate to the middle of the inner bin of the cat litter box (to avoid the cat litter shovel leaving the inner bin of the cat litter box when the inner bin of the cat litter box rotates subsequently, leaving cleaning dead corners), and then the inner bin of the cat litter box can be continued to be controlled to rotate (the rotation direction can be the same as or different from the first set direction), so that the cat litter shovel and the inner bin of the cat litter box can rotate relative to each other, and the inner bin of the cat litter box can be scraped and cleaned by the soft rubber scraping strips provided by the cat litter shovel.

[0121] The set direction refers to the rotation of the inner bin of the cat litter box to achieve the direction of scraping and cleaning the inner bin of the cat litter box, such as clockwise rotation or counterclockwise rotation.

[0122] In the embodiments of the present specification, the cat litter box can be controlled to rotate first so that the water in the inner bin of the cat litter box fully soaks the surface of the inner bin of the cat litter box, and then the cat litter scoop or the inner bin of the cat litter box can be controlled to rotate so that the cat litter scoop and the inner bin of the cat litter box rotate relative to each other, and the inner bin of the cat litter box can be scraped and cleaned by the soft rubber scraping strip provided by the cat litter scoop. Through the relative rotation of the cat litter scoop and the inner bin of the cat litter box, the soft rubber scraping strip included in the cat litter scoop can scrape and clean the small particles of dirt remaining on the inner bin of the cat litter box, so that the inner bin of the cat litter box is fully cleaned, thereby ensuring the cleanliness of the inner bin of the cat litter box.

[0123] In an optional implementation of this embodiment, the cat litter scoop and the inner bin of the cat litter box are controlled to rotate relative to each other, and after the inner bin of the cat litter box is scraped and cleaned, the method further includes:

[0124] After scraping and washing for a set time, the inner bin of the cat litter box is controlled to rotate to the second position, and the sewage in the inner bin of the cat litter box is poured into the sewage tank, wherein the second position is the position for dumping the sewage.

[0125] Specifically, the second position is the position for dumping sewage, and the second position corresponds to the setting position of the sewage tank. From the above, it can be seen that if the sewage tank is also set on the left side of the inner bin of the cat litter box, the second position can be the position of rotating to the right at a set angle so that the opening of the inner bin of the cat litter box is tilted to the left, and the sewage is poured into the sewage tank from the left.

[0126] The sewage tank refers to a collection device for collecting sewage generated by washing. The sewage tank can be the same device as the sewage collection bin, that is, sewage, dirt generated by excretion, waste sand, etc. are all collected in the sewage collection bin. Alternatively, the sewage tank can be a different device from the sewage collection bin, and sewage and dirt generated by excretion and waste sand are collected separately.

[0127] It should be noted that after scraping and washing for the set time, the inner bin of the cat litter box has been scraped and washed clean. At this time, the inner bin of the cat litter box can be controlled to rotate to the second position, and the sewage in the inner bin of the cat litter box can be poured into the sewage tank to complete the water cleaning process, thereby realizing automatic water cleaning of the smart cat litter box and ensuring that the smart cat litter box is clean and hygienic.

[0128] In the embodiment of this specification, the cat litter scoop and the inner bin of the cat litter box are controlled to rotate relative to each other, and after the inner bin of the cat litter box is scraped and cleaned, the method further includes:

[0129] The inner bin of the cat litter box is controlled to remain stationary, and the cat litter shovel is controlled to rotate at least once along a second set direction to scrape off water stains remaining in the inner bin of the cat litter box.

[0130] Among them, the second set direction refers to a pre-set direction in which the cat litter shovel rotates along the inner bin of the cat litter box to scrape off residual water stains, such as clockwise, counterclockwise, etc.

[0131] It should be noted that, by controlling the cat litter scoop and the inner bin of the cat litter box to rotate relative to each other, after scraping and washing the inner bin of the cat litter box, although the dirt in the inner bin of the cat litter box is scraped and washed clean, the sewage generated by scraping and washing will remain on the surface of the inner bin of the cat litter box. Therefore, the inner bin of the cat litter box can be controlled to remain stationary and the cat litter scoop can be controlled to rotate at least once along the second set direction to scrape off the remaining water stains in the inner bin of the cat litter box, further fully clean the inner bin of the cat litter box, and ensure the cleanliness of the inner bin of the cat litter box.

[0132] For example, the inner bin of the cat litter box is controlled to be fixed, and the cat litter scoop is rotated clockwise for 2 circles, so that the soft rubber scraper included in the cat litter scoop scrapes the water stains remaining on the surface of the inner bin of the cat litter box into the sewage tank.

[0133] In an optional implementation of this embodiment, the cleaning mode is a dirt removal mode, and the dirt removal mode includes:

[0134] The cat litter scoop is controlled to rotate in a circle from an initial position to a third position, and dirt in the inner bin of the cat litter box is scooped up by the cat litter scoop during the rotation, wherein the third position is a position for dumping dirt.

[0135] Specifically, the third position is the position for dumping dirt, and the second position corresponds to the setting position of the dirt collecting bin. For example, the dirt collecting bin is on the left side of the inner bin of the cat litter box, and the third position can be the left-side throwing position; or, the dirt collecting bin can also be on the right side of the inner bin of the cat litter box, and the third position can be the right-side throwing position.

[0136] It should be noted that when removing dirt, after the smart cat litter box is powered on, the system control can make the entire cat litter shovel rotate in a circle under the action of the motor. When passing through the cat litter, the cat litter shovel will scoop up the dirt in the cat litter and separate the dirt from the clean cat litter, leaving the clean cat litter for continued use. The cat litter shovel rotates to the position for dumping the dirt and pours the dirt into the dirt collecting bin, thereby automatically removing the dirt, improving the efficiency of removing dirt, and freeing the user's hands.

[0137] In addition, the above-mentioned water cleaning mode and dirt removing mode can also be executed. In this case, the cleaning instruction carries the water cleaning mode and the dirt removing mode. At this time, the cleaning control strategy is to first execute the rotation control corresponding to the dirt removing mode, and then execute the rotation control corresponding to the water cleaning mode.

[0138] The cleaning control method of the smart cat litter box provided in the embodiment of this specification, the smart cat litter box includes a cat litter scoop and a cat litter box inner bin that can rotate respectively, the cat litter scoop is equipped with a water spraying part, through the corresponding cleaning mode, the cat litter scoop and / or the cat litter box inner bin can be controlled to rotate, through the rotation of the cat litter scoop and / or the cat litter box inner bin, the dirt in the cat litter box inner bin can be removed, and / or the cat litter scoop and the cat litter box inner bin can be cleaned with water by the water flow sprayed by the water spraying part. In this way, the dirt in the cat litter box inner bin can be automatically scraped off, and the cat litter scoop and the cat litter box inner bin can be automatically cleaned with water by the water flow sprayed by the water spraying part, which combines automatic removal of dirt and automatic water cleaning, and automatically and efficiently cleans the cat litter box. The functions of the cat litter box are more diverse and more concentrated, and no user intervention is required, which frees the user's hands and allows users to keep pets cleaner.

[0139] Corresponding to the above method embodiment, this specification also provides an embodiment of a cleaning control unit of an intelligent cat litter box, Fig.16 The schematic diagram of the structure of a cleaning control unit of an intelligent cat litter box provided by an embodiment of the present specification is shown, which is applied to the above Figure 1-Figure 13 The smart cat litter box shown, Fig.16 As shown, the cleaning control unit includes:

[0140] The receiving module 1602 is configured to receive a cleaning instruction for the smart cat litter box, wherein the cleaning instruction carries a cleaning mode;

[0141] The determination module 1604 is configured to determine a corresponding cleaning control strategy according to the cleaning mode;

[0142] The control module 1606 is configured to control the cat litter scoop and / or the inner bin of the cat litter box to rotate according to the cleaning control strategy, thereby removing dirt in the inner bin of the cat litter box through the rotation, and / or using the water flow sprayed by the water spray part to clean the cat litter scoop and the inner bin of the cat litter box.

[0143] In an optional implementation of this embodiment, the cleaning mode is a water cleaning mode; the control module 1606 is further configured as follows:

[0144] The water spraying part passes water, and water is sprayed toward the cat litter scoop through the water spraying part;

[0145] Stop passing water to the water spraying part, control the cat litter scoop and the inner bin of the cat litter box to rotate relative to each other, and scrape and clean the inner bin of the cat litter box.

[0146] In an optional implementation of this embodiment, the control module 1606 is further configured to:

[0147] Controlling the inner bin of the cat litter box to rotate from an initial position to a first position, wherein the first position is a position for pouring waste litter in the inner bin of the cat litter box into a waste collection bin;

[0148] After the set time, the inner compartment of the cat litter box is controlled to return from the first position to the initial position.

[0149] In an optional implementation of this embodiment, the control module 1606 is further configured to:

[0150] The cat litter scoop is controlled to rotate to a vertical downward state, and the cat litter scoop is cleaned by water flow sprayed by the water spraying part, and then the water flow flows into the inner bin of the cat litter box.
