Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pet supplies, and in particular to a pet toilet and its door curtain frame assembly. Background Technology
[0002] Currently, pet toilets often have curtains installed to selectively seal off the excrement space and isolate odors, as the smell of excrement cannot be effectively purified or isolated. However, for pet toilets with automatic cleaning functions, the excrement space needs to rotate repeatedly during the cleaning process, making the curtains used in conventional pet toilets unsuitable for the rotating space of these automatic toilets. Utility Model Content
[0003] The main purpose of this utility model is to provide a pet toilet and its curtain frame assembly, which can solve the problem that the curtain of conventional pet toilets cannot be adapted to the pivot space of automatic pet toilets in related technologies.
[0004] In a first aspect, embodiments of this application provide a door curtain frame assembly for a pet toilet; the door curtain frame assembly includes a door curtain frame, which is pivotally connected to the open end face of the ball chamber assembly of the pet toilet. The door curtain frame has an inlet, and the pivotal relationship is such that the door curtain frame can freely pivot around the opening of the ball chamber assembly in the radial plane of the opening of the ball chamber assembly. The door curtain frame is constrained by an external force and remains relatively stationary with respect to the base of the pet toilet. When the ball chamber assembly pivots relative to the base under the action of the driving component of the pet toilet, the door curtain frame remains relatively stationary with respect to the base under the constraint of the external force and pivots relative to the ball chamber assembly.
[0005] Secondly, this application provides a pet toilet; the pet toilet includes a base, a drive assembly, a ball chamber assembly, and the aforementioned door curtain frame assembly. The drive assembly is mounted on the base, and the ball chamber assembly is detachably mounted on the base and connected to the drive end of the drive assembly. The ball chamber assembly is configured to rotate relative to the base around its own axis under the drive of the drive assembly. The ball chamber assembly includes a working chamber, a screening chamber, and a feces collection chamber. The working chamber, screening chamber, and feces collection chamber are connected to form a structure with a rotating outer perimeter. The feces collection chamber has an opening for cat feces to enter the chamber. The ball chamber assembly also includes a feces collection chamber cover assembly, which is provided corresponding to the opening of the feces collection chamber and configured to open or close the opening of the feces collection chamber. The door curtain frame is pivotally connected to the open end face of the ball chamber assembly.
[0006] Based on the pet toilet and its door curtain frame assembly according to the embodiments of this application, by designing the door curtain frame to be pivotally connected to the opening end face of the ball chamber assembly, and designing the door curtain frame to be constrained by external force and remain relatively stationary with the base, when the drive assembly drives the ball chamber assembly to rotate relative to the base, the door curtain frame remains relatively stationary with the base due to the constraint of external force, so that the door curtain frame assembly will not rotate with the ball chamber assembly, thereby effectively blocking the opening of the ball chamber assembly. At the same time, the ball chamber assembly rotates relative to the door curtain frame under the action of the drive assembly, which can effectively clean the feces in the cat litter.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-4As shown, this utility model proposes a pet toilet 1, which includes a base 10, a drive assembly 20, a ball chamber assembly 30, and a curtain frame assembly 40. The drive assembly 20 is mounted on the base 10. The ball chamber assembly 30 is detachably mounted on the base 10 and connected to the drive end of the drive assembly 20. The ball chamber assembly 30 is configured to rotate relative to the base 10 around its own axis under the drive of the drive assembly 20. The curtain frame 41 of the curtain assembly 42 (described below) is pivotally connected to the opening 30a end face of the ball chamber assembly 30.
[0025] The base 10 serves as the foundation for the pet toilet 1, providing support for other components. The specific structure of the base 10 is not limited here; designers can design it appropriately according to actual needs. Similarly, the specific material of the base 10 is not limited here; designers can choose it appropriately according to actual needs.
[0026] The drive assembly 20 serves as the driving structure for the pet toilet 1, driving the ball chamber assembly 30 to rotate relative to the base 10, thereby effectively separating cat litter and feces during the rotation of the ball chamber assembly 30. The specific structure of the drive assembly 20 is not limited here; designers can design it appropriately according to actual needs. For example, the drive assembly 20 may include a bracket and a motor, with the bracket fixedly connected to the base 10, the motor mounted on the bracket, and the motor's shaft connected to the ball chamber assembly 30 as the drive end.
[0027] The ball-shaped container assembly 30 includes a working chamber 31, a screening chamber 32, and a waste collection chamber 33. The working chamber 31 is used for the cat to defecate, the screening chamber 32 is used to separate cat litter and feces, and the waste collection chamber 33 is used to store the filtered feces. The working chamber 31, screening chamber 32, and waste collection chamber 33 are connected to form a structure with a rotating outer perimeter. It should be noted that the ball-shaped container assembly 30 rotates relative to the base 10, allowing the cat litter and feces to be effectively separated within the screening chamber 32.
[0028] The spherical chamber assembly 30 also includes a fecal collection chamber cover assembly 34, which corresponds to the opening of the fecal collection chamber 33 and is configured to open or close the opening of the fecal collection chamber 33. The specific structure of the fecal collection chamber cover assembly 34 is not limited here; designers can design it reasonably according to actual needs. The specific opening and closing method of the fecal collection chamber cover assembly 34 is not limited here; designers can design it reasonably according to actual needs. For example, the fecal collection chamber cover assembly 34 can open or close the opening of the fecal collection chamber 33 by sliding; or, for example, the fecal collection chamber cover assembly 34 can also open or close the opening of the fecal collection chamber 33 by rotating. When there is no need to sift cat litter and feces, the feces collection chamber cover assembly 34 moves to close the opening of the feces collection chamber 33; when there is a need to sift cat litter and feces, the feces collection chamber cover assembly 34 moves to open the opening of the feces collection chamber 33 to ensure that the feces sifted from the sifting chamber 32 can smoothly enter the chamber of the feces collection chamber 33 from the opening of the feces collection chamber 33.
[0029] It should be noted that since the base 10, drive assembly 20, working chamber 31, screening chamber 32, and waste collection chamber 33 are not the focus of this utility model application, their specific structures will not be described in detail here. However, the curtain frame assembly 40 is the focus of this utility model application, and its specific structure will be described in detail below.
[0030] like Figure 1 As shown, the door curtain frame assembly 40 includes a door curtain frame 41, which is pivotally connected to the end face of the opening 30a of the ball chamber assembly 30. The door curtain frame 41 has an inlet 41a. The pivotal relationship is such that the door curtain frame 41 can freely pivot around the opening 30a of the ball chamber assembly 30 in the radial plane, while the door curtain frame 41 is constrained in the axial direction of the opening 30a. The door curtain frame 41 is constrained by an external force, and remains relatively stationary with respect to the base 10. When the ball chamber assembly 30 pivots relative to the base 10 under the action of the drive assembly 20, the door curtain frame 41 remains relatively stationary with respect to the base 10 under the constraint of the external force, and pivots relative to the ball chamber assembly 30.
[0031] In this invention, by designing the curtain frame 41 to be pivotally connected to the opening 30a end face of the ball chamber assembly 30, and by designing the curtain frame 41 to be constrained by external forces and remain relatively stationary with respect to the base 10, when the drive assembly 20 drives the ball chamber assembly 30 to rotate relative to the base 10, the curtain frame 41 remains relatively stationary with respect to the base 10 due to the constraint of external forces. This prevents the curtain frame assembly 40 from rotating with the ball chamber assembly 30, thereby effectively blocking the opening 30a of the ball chamber assembly 30. At the same time, the ball chamber assembly 30 rotates relative to the curtain frame 41 under the action of the drive assembly 20, which can effectively clean feces from the cat litter.
[0032] The way to keep the curtain frame 41 relatively stationary with the base 10 under the constraint of external forces can be achieved, but is not limited to, through the following types of external forces.
[0033] In the first scenario, the external force constraint on the curtain frame 41 is the resistance formed by one end of the curtain frame 41 contacting the base 10. It is understood that the rolling friction generated by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball chamber assembly 30 will cause the curtain frame 41 to tend to rotate relative to the base 10 following the ball chamber assembly 30. At this time, since the static friction (i.e., the external force constraint) formed by the contact between one end of the curtain frame 41 and the base 10 is greater than the rolling friction generated by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball chamber assembly 30, the curtain frame 41 can remain stationary relative to the base 10.
[0034] In the second scenario, the external constraint on the curtain frame 41 is the resistance formed by the insertion of the extension of the curtain frame 41 into the base 10. It is understood that the rolling friction generated by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball chamber assembly 30 will cause the curtain frame 41 to tend to rotate relative to the base 10 following the ball chamber assembly 30. At this time, the extension of the curtain frame 41 is inserted into the base 10, and the base 10 acts as a limiter on the extension of the curtain frame 41. This allows the extension of the curtain frame 41 to compress the base 10, and according to the action and reaction forces, the base 10 will also compress the extension of the curtain frame 41. Thus, the curtain frame 41 can remain stationary relative to the base 10 under the compressive force (i.e., external constraint) of the base 10.
[0035] In the third case, the external force constraining the curtain frame 41 is such that the center of gravity W1 of the curtain frame 41 is located on the side close to the base 10, that is, below the rotation center axis OO of the ball compartment assembly 30. The above arrangement makes the curtain frame 41 relatively stationary with respect to the base 10 and relatively pivoting with respect to the ball compartment assembly 30 when the ball compartment assembly 30 pivots relative to the base 10 under the action of the drive assembly 20. It is understandable that the rolling friction generated by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball compartment assembly 30 will cause the curtain frame 41 to tend to rotate relative to the base 10 along with the ball compartment assembly 30. At this time, the center of gravity W1 of the curtain frame 41 is positioned on the side closer to the base 10 relative to the rotation center axis OO of the ball compartment assembly 30, so that the gravity of the curtain frame 41 (i.e., external force constraint) is greater than the rolling friction generated by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball compartment assembly 30, so that the curtain frame 41 can remain stationary relative to the base 10.
[0036] like Figure 1 As shown, the curtain frame assembly 40 also includes a curtain assembly 42, which is connected to the curtain frame 41 to cover at least a portion of the inlet 41a of the ball chamber assembly 30. For example, the curtain assembly 42 can cover half, three-quarters, or completely cover the inlet 41a of the ball chamber assembly 30. By designing the curtain assembly 42 connected to the curtain frame 41, the curtain assembly 42 can block at least a portion of the inlet 41a of the ball chamber assembly 30, thus masking the odor of feces.
[0037] The curtain assembly 42 is detachably connected to the curtain frame 41. For example, the curtain assembly 42 can be detachably connected to the curtain frame 41 by means of Velcro, magnetic attraction, or snap-fit. It is understood that the specific detachable connection method between the curtain assembly 42 and the curtain frame 41 will vary depending on the specific structure of the curtain assembly 42.
[0038] like Figure 1 , Figures 5-14 As shown, the curtain frame 41 serves as the frame of the curtain frame assembly 40 and is used to connect the curtain assembly 42 and the opening 30a end face of the ball chamber assembly 30. The specific structure of the curtain frame 41 may include, but is not limited to, the following embodiments.
[0039] In the first embodiment, such as Figure 1 , Figures 5-8As shown, the door curtain frame 41 includes a frame body 411, which includes an inner frame 4111, a face frame 4112 connecting the edge of the inner frame 4111, and an outer frame 4113 connecting the face frame 4112 on the side away from the inner frame 4111. The inner frame 4111, the face frame 4112, and the outer frame 4113 form a receiving portion 4114, which is used to receive at least a portion of the barrel ring 35 at the opening 30a of the ball compartment assembly 30. The inner frame 4111, the face frame 4112, and the outer frame 4113 can be either separate or integrated. For example, when the inner frame 4111, the face frame 4112, and the outer frame 4113 are separate, they can be detachably connected by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, they can be non-detachably connected by gluing or riveting. When the inner frame 4111, the face frame 4112, and the outer frame 4113 are integrated, they can be integrally formed by injection molding or 3D printing, but are not limited to this method. By designing the inner frame 4111, the face frame 4112, and the outer frame 4113, the inner frame 4111, the face frame 4112, and the outer frame 4113 enclose and form a receiving cavity, at least a portion of the barrel ring 35 at the opening 30a of the ball compartment assembly 30 is received in the receiving cavity, thus enabling a pivotal connection between the curtain frame 41 and the ball compartment assembly 30.
[0040] One of the frame 411 and the curtain assembly 42 includes at least one latch 4115, and the other of the frame 411 and the curtain assembly 42 includes at least one latching hole 42a. The at least one latch 4115 is detachably installed in the at least one latching hole 42a, thus detachably connecting the frame 411 and the curtain assembly 42. The specific connection method between the latch 4115 and the frame 411 (curtain assembly 42) is not limited here; designers can design it reasonably according to actual needs. For example, the latch 4115 can be detachably connected to the frame 411 (curtain assembly 42) by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the latch 4115 can also be non-detachably connected to the frame 411 (curtain assembly 42) by means of gluing, injection molding, or 3D printing, but not limited to these methods. By designing a tenon 4115 and a locking hole 42a, the tenon 4115 engages with the locking hole 42a to achieve the installation between the frame 411 and the curtain assembly 42, and the tenon 4115 disengages from the locking hole 42a to achieve the disassembly between the frame 411 and the curtain assembly 42. The structure is simple and easy to implement.
[0041] Specifically, such as Figures 5-8As shown, the specific location and structural design of the tenon 4115 and the hole 42a may include, but are not limited to, one or more of the following situations.
[0042] In one configuration, at least one latch 4115 is provided on the upper part of the inner frame 4111 or the upper part of the curtain assembly 42. For example, when at least one latch 4115 is provided on the upper part of the inner frame 4111, at least one latching hole 42a is provided on the upper part of the curtain assembly 42, corresponding one-to-one with the at least one latch 4115; or, for another example, when at least one latch 4115 is provided on the upper part of the curtain assembly 42, at least one latching hole 42a is provided on the upper part of the inner frame 4111, corresponding one-to-one with the at least one latch 4115. It should be noted that when there is only one latch 4115, this latch 4115 can be located on the upper part of the inner frame 4111 or on the upper part of the curtain assembly 42; when there are multiple latches 4115, all latches 4115 can be located on the upper part of the inner frame 4111 or all can be located on the upper part of the curtain assembly 42, or some latches 4115 can be located on the upper part of the inner frame 4111 and the remaining latches 4115 can be located on the upper part of the curtain assembly 42. By designing the latches 4115 on the upper part of the inner frame 4111 or the upper part of the curtain assembly 42, it is convenient for the curtain assembly 42 to hook onto the frame 411, and the curtain assembly 42 can effectively block the opening 30a of the ball chamber assembly 30.
[0043] In another embodiment, at least one latch 4115 includes a connecting portion 4115a and a latching end 4115b connecting the connecting portion 4115a. The diameter of the latching end 4115b is larger than the diameter of the latching hole 42a and the diameter of the connecting portion 4115a. At least one of the latching end 4115b and the latching hole 42a is deformable so that the latching end 4115b can pass through the latching hole 42a. The latching end 4115b and the connecting portion 4115a can be integrally formed, but are not limited to, by injection molding or 3D printing. By designing a connecting part 4115a and a snap-fit end 4115b, the connecting part 4115a is used to connect the snap-fit end 4115b to the frame 411, and the snap-fit end 4115b is used to press against the wall of the snap hole 42a. At least one of the snap-fit end 4115b and the snap hole 42a can deform under the action of the pressing force so that the snap-fit end 4115b passes through the snap hole 42a, thereby realizing the snap-fit connection between the two, and thus achieving the relative fixation of the position between the curtain assembly 42 and the frame 411.
[0044] like Figure 1 , Figures 5-8As shown, the curtain assembly 42 includes a curtain 421, which effectively blocks the opening 30a of the ball compartment assembly 30. The curtain 421 is detachably mounted on the curtain frame 41.
[0045] Specifically, the specific structural design of the curtain 421 may include, but is not limited to, one or more of the following situations.
[0046] In one scenario, the curtain 421 is a flexible curtain 421. The material of the curtain 421 can be, but is not limited to, flexible fabric, flexible silicone, or flexible rubber. By designing the curtain 421 to be flexible, it facilitates the entry and exit of the pet cat through the opening 30a of the ball pit assembly 30.
[0047] In another configuration, the curtain 421 includes a first curtain 421a and a second curtain 421b, which are respectively installed on the left and right sides of the inlet 41a of the frame 411, and an opening 421c is formed between the first curtain 421a and the second curtain 421b. By designing the curtain 421 with the first curtain 421a and the second curtain 421b arranged on the left and right sides, and forming an opening 421c between the first curtain 421a and the second curtain 421b for the pet cat to enter and exit, it is convenient for the pet cat to enter and exit the opening 30a of the ball pit assembly 30.
[0048] like Figures 5-8 As shown, the curtain frame 41 also includes at least one fastener 412, which is disposed on the frame 411 and used to engage with the edge of the barrel ring 35. The specific connection method between the fastener 412 and the frame 411 is not limited here; designers can design it reasonably according to actual needs. For example, the fastener 412 can be detachably connected to the frame 411 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the fastener 412 can be non-detachably connected to the frame 411 by, but not limited to, gluing, riveting, injection molding, or 3D printing.
[0049] Specifically, the fastener 412 serves as a connecting structure for the curtain frame 41 to achieve the connection between the frame 411 and the barrel ring 35 of the ball compartment assembly 30. The specific location and shape of the fastener 412 may include, but are not limited to, one or more of the following situations.
[0050] In one configuration, at least one fastener 412 is disposed on the upper portion of the frame 411. For example, when there is only one fastener 412, that single fastener 412 is disposed on the upper portion of the frame 411; or, when there are multiple fasteners 412, all of the fasteners 412 may be disposed on the upper portion of the frame 411, or some of the fasteners 412 may be disposed on the upper portion of the frame 411, with the remaining fasteners 412 disposed on the lower portion of the frame 411. By disposing of at least one fastener 412 on the upper portion of the frame 411, a connection can be achieved between the upper portion of the frame 411 and the barrel ring 35 of the ball compartment assembly 30.
[0051] In another scenario, at least one fastener 412 is connected to the inside of the outer frame 4113. For example, when there is only one fastener 412, that single fastener 412 is connected to the inside of the outer frame 4113; or, when there are multiple fasteners 412, all of them may be connected to the inside of the outer frame 4113, or some of them may be connected to the inside of the outer frame 4113 and the remaining fasteners 412 to the outside of the inner frame 4111. By designing at least one fastener 412 to be on the inside of the outer frame 4113, the connection between the frame 411 and the barrel ring 35 of the ball compartment assembly 30 can be achieved from the side where the inner side of the outer frame 4113 is located, facilitating the installation and removal of the curtain frame 41 and the barrel ring 35 of the ball compartment assembly 30.
[0052] In another case, at least one snap fastener 412 has a V-shaped latch for engaging with the edge of the tub ring 35. Designing a V-shaped latch on at least one snap fastener 412 for engaging with the edge of the tub ring 35 results in a simple structure that is easy to implement. Of course, the snap fastener 412 can also have a C-shaped latch for engaging with the edge of the tub ring 35.
[0053] like Figures 8-14As shown, in the second embodiment, the curtain frame 41 includes a frame body 411, which includes an inner frame 4111, a face frame 4112 connecting the edge of the inner frame 4111, and an outer frame 4113 connecting the face frame 4112 on the side away from the inner frame 4111. The inner frame 4111, the face frame 4112, and the outer frame 4113 form a receiving portion 4114, which is used to receive at least a portion of the barrel ring 35 at the opening 30a of the ball compartment assembly 30. The inner frame 4111, the face frame 4112, and the outer frame 4113 can be either separate or integrated. For example, when the inner frame 4111, the face frame 4112, and the outer frame 4113 are separate, they can be detachably connected by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, they can be non-detachably connected by gluing or riveting. When the inner frame 4111, the face frame 4112, and the outer frame 4113 are integrated, they can be integrally formed by injection molding or 3D printing, but are not limited to this method. By designing the inner frame 4111, the face frame 4112, and the outer frame 4113, the inner frame 4111, the face frame 4112, and the outer frame 4113 enclose and form a receiving cavity, at least a portion of the barrel ring 35 at the opening 30a of the ball compartment assembly 30 is received in the receiving cavity, thus enabling a pivotal connection between the curtain frame 41 and the ball compartment assembly 30.
[0054] Unlike the first embodiment described above, in the second embodiment, the inner frame 4111, the front frame 4112, and the outer frame 4113 are all divided into a first part and a second part. The inner frame 4111, the front frame 4112, and the outer frame 4113 of the first part constitute a first frame 411a, and the inner frame 4111, the front frame 4112, and the outer frame 4113 of the second part constitute a second frame 411b. The first frame 411a and the second frame 411b are detachably connected and together form the aforementioned inlet 41a. That is, the frame 411 includes a detachable first frame 411a and a second frame 411b, and the first frame 411a includes an inner frame 4111, a front frame 4112, and an outer frame 4113, and the second frame 411b also includes an inner frame 4111, a front frame 4112, and an outer frame 4113.
[0055] Specifically, such as Figures 8-14 As shown, the specific configuration and connection methods of the first frame 411a and the second frame 411b may include, but are not limited to, one or more of the following situations.
[0056] In one configuration, a first snap fastener 413 is provided on the first frame 411a, and a second snap fastener 414 is provided on the second frame 411b. The first snap fastener 413 and the second snap fastener 414 are detachably fastened together. By designing the first snap fastener 413 on the first frame 411a and the second snap fastener 414 on the second frame 411b, the first frame 411a and the second frame 411b are detachably connected through the snap-fit engagement of the first snap fastener 413 and the second snap fastener 414. This design is simple to operate and easy to implement.
[0057] In another configuration, the first frame 411a and the second frame 411b are respectively the upper frame 411 and the lower frame 411. By designing the first frame 411a and the second frame 411b as an upper and lower frame 411 arranged vertically, the connection point of the first frame 411a and the second frame 411b is a certain distance away from the base 10. This facilitates the relative fixation between the frame 411 and the base 10, and effectively reduces the possibility of loosening between the first frame 411a and the second frame 411b due to collisions at the connection point of the first frame 411a and the second frame 411b during the process of the pet cat entering and exiting the ball chamber assembly 30.
[0058] In another embodiment, the first frame 411a is further provided with a first alignment portion 415 connecting to the face frame 4112 of the first frame 411a, and the second frame 411b is provided with a second alignment portion 416. The first alignment portion 415 and the second alignment portion 416 are aligned and engaged so that the first frame 411a and the second frame 411b are aligned and engaged. The first alignment portion 415 may be an insert connected to the face frame 4112 of the first frame 411a, and the second alignment portion 416 may be a slot provided in the second frame 411b and engaged with the insert. By designing a first alignment part 415 on the face frame 4112 of the first frame 411a and a second alignment part 416 on the second frame 411b, the first alignment part 415 and the second alignment part 416 are connected to achieve pre-positioning, which facilitates the engagement of the first fastener 413 and the second fastener 414, thereby achieving relative fixation of the position between the first frame 411a and the second frame 411b.
[0059] Of course, in other cases, the first frame 411a and the second frame 411b can also be connected by means of screws, pins, or magnetic adsorption, but not limited to screws.
[0060] More specifically, such as Figures 8-14 As shown, the specific structure and setting position of the first fastener 413 and the second fastener 414 may include, but are not limited to, one or more of the following situations.
[0061] In one configuration, one of the first latching member 413 and the second latching member 414 includes an elastic arm 413a and a hook 413b connecting one end of the elastic arm 413a. The other of the first latching member 413 and the second latching member 414 includes a slot 414a, and the hook 413b is used for detachable connection with the slot 414a. The elastic arm 413a and the hook 413b can be integrally formed, but are not limited to, by injection molding or 3D printing. By designing the hook 413b and the elastic arm 413a, the elastic arm 413a is adapted to undergo elastic deformation during the process of the hook 413b hooking the slot 414a, so that the hook 413b and the slot 414a can engage. Of course, one of the first snap fastener 413 and the second snap fastener 414 may also include a snap block (not shown in the figure) and a spring (not shown in the figure), the snap block and the spring forming a wedge block structure, and the other of the second snap fastener 414 includes a snap groove (not shown in the figure), the snap block achieving engagement with the snap groove through the extension and retraction of the spring.
[0062] In another configuration, the elastic arm 413a is connected to the outer frame 4113 of the first frame 411a, and the slot 414a is located on the outer frame 4113 of the second frame 411b. The elastic arm 413a can be integrally formed with the outer frame 4113 of the first frame 411a by injection molding or 3D printing, but is not limited to this method. By designing the elastic arm 413a on the outer frame 4113 of the first frame 411a and the slot 414a on the outer frame 4113 of the second frame 411b, the connection between the first frame 411a and the second frame 411b is achieved from the side where the outer frame 4113 is located, facilitating the installation and disassembly of the first frame 411a and the second frame 411b.
[0063] In another scenario, after the first frame 411a and the second frame 411b are aligned and engaged, the hook 413b engages in the slot 414a, and the inner frame 4111, face frame 4112, and outer frame 4113 of the first frame 411a are engaged with the inner frame 4111, face frame 4112, and outer frame 4113 of the second frame 411b, respectively. This ensures that the first frame 411a and the second frame 411b remain relatively flat on the side where the inner frame 4111 is located, the side where the face frame 4112 is located, and the side where the outer frame 4113 is located.
[0064] Based on the first and second embodiments described above, other structural designs for the curtain frame assembly 40 may include, but are not limited to, one or more of the following situations.
[0065] In one embodiment, the curtain frame 41 further includes a fastener 417, one end of which is connected to the frame 411, and the other end of which is used for detachable connection to the base 10 of the pet toilet 1. For example, based on the first embodiment described above, the fastener 417 may be a fixing plate 417a connected to the bottom end of the frame 411 (e.g., Figure 5 and Figure 6 As shown in the figure, the base 10 of the pet toilet 1 is provided with a fixing hole (not shown in the figure) corresponding to the fixing plate 417a. The fixing plate 417a is inserted into the fixing hole to achieve relative fixation between the door curtain frame 41 and the base 10. When the ball chamber assembly 30 rotates relative to the base 10 under the action of the drive assembly 20, the rolling friction formed by the relative rotation between the door curtain frame 41 and the end face of the opening 30a of the ball chamber assembly 30 will cause the door curtain frame 41 to have a tendency to rotate relative to the base 10 with the ball chamber assembly 30. At this time, the fixing plate 417a is inserted into the fixing hole, and the hole wall of the fixing hole plays a limiting role on the fixing plate 417a. When the fixing part squeezes the hole wall of the fixing hole, the hole wall of the fixing hole will also squeeze the fixing plate 417a according to the action and reaction forces. Thus, the door curtain frame 41 can remain stationary relative to the base 10 under the squeezing force (i.e., external force constraint) of the hole wall of the fixing hole. For example, based on the second embodiment described above, the fastener 417 may be a fixing flange 417b connected to the bottom end of the frame 411 (e.g., Figure 10 As shown in the figure, at this time, a fixed gap (not shown in the figure) is formed between the base 10 of the pet toilet 1 and the ball chamber assembly 30. The fixed flange 417b is inserted into the fixed gap to achieve relative fixation between the curtain frame 41 and the base 10. When the ball chamber assembly 30 rotates relative to the base 10 under the action of the drive assembly 20, the rolling friction formed by the relative rotation between the curtain frame 41 and the end face of the opening 30a of the ball chamber assembly 30 will cause the curtain frame 41 to have a tendency to rotate with the ball chamber assembly 30 relative to the base 10. At this time, the fixed flange 417b is inserted into the fixed gap, and the base 10 and the ball chamber assembly 30 clamp the fixed flange 417b, so that the clamping force of the base 10 and the ball chamber assembly 30 on the fixed flange 417b is greater than the rolling friction formed by the relative rotation between the end face of the opening 30a of the curtain frame 41 and the ball chamber assembly 30, so that the curtain frame 41 can remain stationary relative to the base 10.
[0066] In another case, such as Figure 6 and Figure 14As shown, the door curtain frame assembly 40 also includes a sand baffle 43, which is disposed in the lower part of the frame 411. For example, in the first embodiment described above, the sand baffle 43 is disposed in the lower part of the frame 411; as another example, in the second embodiment described above, the sand baffle 43 is disposed on the second frame 411b arranged vertically above the first frame 411a. The specific installation method between the sand baffle 43 and the frame 411 is not limited here; designers can design it reasonably according to actual needs. For example, the sand baffle 43 can be detachably connected to the frame 411 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the sand baffle 43 can be non-detachably connected to the frame 411 by, but not limited to, gluing, riveting, injection molding, or 3D printing. By designing the sand baffle 43, during the rotation of the ball chamber assembly 30 relative to the base 10 under the action of the drive assembly 20, the sand baffle 43 can effectively prevent cat litter from splashing out of the opening 30a of the ball chamber assembly 30.
