Description

Technical Field

[0001] The utility model relates to the technical field of cat litter boxes, in particular to a drum type cat litter box. Background Art

[0002] Cat litter boxes are mainly used as resting and toilet supplies for pet cats, which are convenient for cleaning pet urine and feces. Therefore, for people who keep pet cats, cat litter boxes are an indispensable and important component. With the continuous expansion of cat users, automatic cat litter boxes are becoming more and more popular.

[0003] One type of existing automatic cat litter boxes is a drum-type cat litter box. After the cat comes in to defecate, this cat litter box can collect waste, such as feces covered with cat litter, agglomerated cat litter after absorbing urine, etc., by rotating the drum, thereby achieving the purpose of automatic litter shoveling; however, the existing drum-type cat litter box has a relatively simple cleaning method, and can only separate coarse and fine cat litter by reciprocating rotation or unidirectional rotation, so as to clean out the waste cat litter; the storage space is small, and the drum-type cat litter box that cleans by reciprocating rotation is usually equipped with a box outside the drum to collect the waste cat litter, and the free space in the drum cannot be used. The drum-type cat litter box that cleans by unidirectional rotation usually has a collection bin directly set on the inner wall of the drum, and the large amount of space outside the drum cannot be used; in addition, some fully automatic drum-type cat litter boxes do not have a weighing structure, so it is impossible to determine whether the pet has entered the drum. If the drum is rotated while the pet is resting, there may be danger, and the change in the pet's weight cannot be monitored. Utility Model Content

DETAILED DESCRIPTION

[0067] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0068] See attached Figure 1 -Attached Figure 5 The utility model embodiment discloses a drum type cat litter box, including a base 1, and also includes a weighing component 2, a transfer component 3, a drum component 4, a driving component 5, a two-way cleaning component 6, and a one-way cleaning component 7. The weighing component 2 is installed on the base 1 for monitoring weight changes; the drum component 4 is rotatably connected to the base 1 for accommodating cat litter and pets; the driving component 5 is installed on the base 1 and drives the drum component 4 to drive the drum component 4 to rotate; the two-way cleaning component 6 is installed in the drum component 4, and the agglomerated cat litter in the drum component 4 can be cleaned out by the reciprocating rotation of the drum component 4; the one-way cleaning component 7 is installed in the drum component 4, and the agglomerated cat litter in the drum component 4 can be cleaned out by the one-way rotation of the drum component 4.

[0069] In actual use, the base 1 is placed at a designated position, and the cat litter is placed in the drum assembly 4. The pet can then enter the drum assembly 4 to rest. At this time, the weighing assembly 2 on the base 1 will monitor the weight change and measure the pet's weight. After the pet leaves the drum assembly 4, a portion of the cat litter will absorb the pet's body fluids and other liquids to form agglomerated cat litter. At this time, the drum assembly 4 can be reciprocated by the driving assembly 5, and the agglomerated cat litter in the drum assembly 4 can be cleaned out in cooperation with the two-way cleaning assembly 6. The drum assembly 4 can be moved unidirectionally, and the one-way cleaning assembly 6 can be used to clean the agglomerated cat litter in the drum assembly 4. The cleaning component 7 cleans the agglomerated cat litter in the drum component 4; since the drum-type cat litter box is provided with a two-way cleaning component 6 and a one-way cleaning component 7, the agglomerated cat litter can be cleaned in two ways, and the design of the two structures can also increase the storage capacity of the agglomerated cat litter; since the drum-type cat litter box is provided with a weighing component 2, the pet weight, the urine and feces weight, the cat litter weight, etc. can be measured by the weight changes at different times; in general, by using the drum-type cat litter box, the cleaning methods and storage space of the agglomerated cat litter are increased, and the weight changes can also be monitored.

[0070] It should be noted that the type, quantity, installation position and other parameters of the weighing component 2 are not limited in the present application and can be flexibly selected according to actual needs. The following example is taken as an example in which the weighing component 2 is installed inside the base 1.

[0071] See attached Figure 5 and attached Figure 6 In order to enable the weighing component 2 to monitor the weight change when the pet enters and exits the drum component 4, the following design is carried out in this embodiment. Specifically, the base 1 is composed of a shell 101 and an adapter component 3. The weighing component 2 is connected to the shell 101 at the bottom and to the adapter component 3 at the top. There is a distance between the adapter component 3 and the shell 101. The drum component 4 is rotatably connected to the adapter component 3. A plurality of weighing feet 8 are arranged at the bottom of the adapter component 3. The weighing component 2 includes an upper connecting member 21, a weighing sensor 22, and a lower connecting member 23. A plurality of weighing feet 8 are connected to the top of the upper connecting member 21. The upper portion of the upper connecting member 21 is provided with a first hole 211, and the lower portion is provided with a second hole 212. The first hole 211 and the second hole 212 They are all vertically arranged and interconnected, the diameter of the first hole 211 is larger than the diameter of the second hole 212; the edge of the weighing sensor 22 is fixed between the upper connecting member 21 and the multiple weighing feet 8, and the middle part is suspended; the bottom of the lower connecting member 23 is connected to the shell 101, the upper part 231 of the lower connecting member 23 abuts the middle part of the weighing sensor 22, the middle part 232 of the lower connecting member 23 is slidably connected in the first hole 211, and the lower part 233 of the lower connecting member 23 is slidably connected in the second hole 212, the vertical height of the lower connecting member 23 is larger than the vertical height of the upper connecting member 21, and there is a distance between the upper connecting member 21 and the shell 101, so that the weighing sensor 22 can monitor the change of weight above the adapter assembly 3.

[0072] Through the design of the above structure, the upper connecting member 21 in the weighing component 2 plays a role of connection and fixing, so that the adapter component 3, the weighing foot 8, the upper connecting member 21 and the weighing sensor 22 can move at the same time, and the lower connecting member 23 plays a supporting role. All components except the shell 101 and the lower connecting member 23 itself are supported by the lower connecting member 23, and the side of the lower connecting member 23 is slidably connected to the upper connecting member 21 through the first hole 211 and the second hole 212, and the top abuts the weighing sensor 22. Therefore, the force on the lower surface of the weighing sensor 22 is the same as the force on the upper surface of the lower connecting member 23, but in the opposite direction, so that the weighing sensor 22 can monitor the changes in the total weight of the upper components.

[0073] The fully automatic cat litter boxes with weighing structures on the market usually have the weighing structure externally placed, such as being set at the bottom of the shell of the above-mentioned fully automatic cat litter box. This leads to certain requirements for the placement of these fully automatic cat litter boxes, that is, they must be placed on a hard ground, have a small scope of application, and are easily disturbed, such as stains on the shell, which easily affects the final measurement result. The drum-type cat litter box in this embodiment, since the weighing component 2 is built into the base 1, can be applied to more ground environments, has a wider scope of application, and is not easily disturbed. Stains on the outside of the shell 101 will not affect the measurement result of the weighing component 2, so that the weighing component 2 in this embodiment can more accurately monitor the change in weight, thereby more accurately sensing and protecting the pet.

[0074] Furthermore, the model of the weighing sensor is 928DAD-10KG, which can monitor the weight change through the deformation, thereby realizing the weighing function; it should be noted that at this time, the size of the cross-section of the protrusion 231 should be smaller than the size of the cross-section of the weighing sensor 22 and the first hole 211, so that the protrusion 231 can abut against the middle part of the weighing sensor 22.

[0075] See attached Figure 3 , Attachment Figure 5 and attached Figure 7 There are many structures that can transfer different components. One of them is introduced in this embodiment. Specifically, the transfer assembly 3 includes a horizontal portion 31 and a vertical portion 32. The bottom of the horizontal portion 31 is connected to the weighing assembly 2, and the top is arranged in an arc shape to prevent affecting the rotation of the roller assembly 4; the vertical portion 32 is provided with an annular snap structure 33 and is connected to the roller assembly 4 through the snap structure 33, so that the roller assembly 4 can be rotated and detachably connected to the vertical portion 32.

[0076] Through the design of the above structure, on the basis of the rotatable drum assembly 4, the drum assembly 4 can also be detachably connected to the vertical portion 32, so that the user of the drum type cat litter box can remove the entire drum assembly 4. Compared with the entire drum type cat litter box, the single drum assembly 4 is lighter and easier to move and clean.

[0077] Since the roller assembly 4 is mounted on the vertical portion 32 via a snap-fit ​​structure 33, the connection between the roller assembly 4 and the vertical portion 32 is obviously inconvenient to rotate compared to an ordinary shaft. In order to solve the above problem, the following design is implemented in this embodiment. Specifically, multiple pulleys 34 are provided on the horizontal portion 31 and the snap-fit ​​structure 33, and the multiple pulleys 34 are all slidably connected to the roller assembly 4 to reduce the friction force applied to the roller assembly 4 during rotation.

[0078] Through the design of the above structure, the roller assembly 4 as a whole can be assisted by multiple pulleys 34, reducing the friction between the roller assembly 4 and the vertical portion 32, and the lower part of the roller assembly 4 can be supported by multiple pulleys 34, so that the connection between the roller assembly 4 and the vertical portion 32 will not be affected by forces other than friction. In general, the force that needs to be overcome during the rotation process is smaller, and it is easier to rotate.

[0079] Furthermore, the multiple pulleys 34 on the horizontal portion 31 and the snap-fit ​​structure 33 can be evenly distributed to make the force on the roller assembly 4 more uniform. For example, the multiple pulleys 34 on the horizontal portion 31 can be arranged linearly or in a rectangular array, and the multiple pulleys 34 on the snap-fit ​​structure 33 can be arranged in a circular array.

[0080] See attached Figure 7 and attached Figure 8 The cam 332 is a vertically extending structure that is configured to move the roller assembly 4 toward the top of the support 32. The cam 332 is a vertically extending structure that is configured to move the roller assembly 4 toward the bottom of the support 32. The cam 332 is a vertically extending structure that is configured to move the roller assembly 4 toward the top of the support 32.

[0081] Through the design of the above structure, the clamping member 331 can be opened to remove the roller assembly 4, or the clamping member 331 can be closed to connect the roller assembly 4 to the vertical portion 32, which has the advantages of simple structure, reliable connection, and easy disassembly and assembly.

[0082] The specific method and structure of the detachable connection between the clamping member 331 and the vertical portion 32 are not limited in the present application and can be flexibly selected according to actual needs, such as connecting with bolts, locking with latches, etc.

[0083] See attached Figure 1 and attached Figure 8 -Attached Fig.12 In order to enable the drum assembly 4 to accommodate cat litter and allow pets to enter and exit, the following design is performed in this embodiment. Specifically, the drum assembly 4 includes a cylinder 41 and a shielding member 42. A substantially cylindrical cavity 411 is provided inside the cylinder 41 for accommodating pets and cat litter. A first opening 412 having a circular cross-section and communicating with the cavity 411 is provided at one end away from the vertical portion 32 for allowing pets to enter and exit. The size of the first opening 412 is smaller than the size of the cavity 411 to prevent the pet from entering and exiting the cavity 411. The shielding member 42 is installed at the first opening 412 of the cylinder 41, and the shielding member 42 has a first shielding portion 421 located inside the cylinder 41 and a second shielding portion 422 located outside the cylinder 41. The first shielding portion 421 is vertically arranged and extends toward the middle of the cylinder 41 to reduce the size of the first opening 412 and further prevent the pet from bringing out the cat litter when entering and exiting the cavity 411. The second shielding portion 422 is inclined and extends in a direction away from the cylinder 41 to shield the corresponding lower part.

[0084] Through the design of the above structure, the drum assembly 4 can have the function of accommodating cat litter and providing a resting place for pets. The first shielding portion 421 can reduce the possibility of cat litter being carried out by pets, and the second shielding portion 422 can prevent liquid or cat litter from falling and dirtying the adapter assembly 3 and the base 1 directly below the second shielding portion 422.

[0085] See attached Figure 2 , Attachment Figure 4 and attached Figure 8 In order to enable the roller assembly 4 to rotate under the action of the driving assembly 5, the following design is carried out in this embodiment. Specifically, a ring gear 10 is provided on the roller assembly 4, and the driving assembly 5 includes a motor 51 and a gear 52. The motor 51 is installed on the shell 101. The driving shaft of the motor 51 is located in a horizontal plane and the extension direction is parallel to the axial direction of the roller assembly 4 when the roller assembly 4 rotates; the gear 52 is installed at the end of the driving shaft and meshes with the ring gear 10, so that the size can drive the ring gear 10 and the roller assembly 4 to rotate under the action of the motor 51.

[0086] Through the design of the above structure, the automatic rotation of the roller assembly 4 can be realized, and under the action of the motor 51, the ring gear 10 and the roller assembly 4 will reverse with the forward rotation of the gear 52, or rotate forward with the reverse rotation of the gear 52, thereby realizing bidirectional reciprocating rotation or unidirectional rotation of the roller assembly 4.

[0087] It should be noted that the specific directions of forward and reverse rotation are not limited in the present application. Forward rotation can be clockwise or counterclockwise, which can be flexibly selected according to actual needs, while reverse rotation is rotation in the direction opposite to the forward direction.

[0088] See attached Figure 3 , Attachment Figure 4 and attached Figure 7 Furthermore, in order to coordinate the relative positions of various components, the gear ring 10 can be set on the side wall of the drum assembly 4, and a through hole 11 can be opened on the horizontal portion 31, so that the upper part of the gear 52 can pass through the through hole 11 to engage the gear ring 10. The overall structure is located inside the drum type cat litter box. On the basis of reliable connection, the exterior of the drum type cat litter box can also be made smoother and more beautiful.

[0089] See attached Figure 1 and attached Fig. 9 -Attached Fig.11 There are various structures that can clean out the agglomerated cat litter through the reciprocating rotation of the drum assembly 4. One of them is introduced in this embodiment. Specifically, the drum assembly 4 has an initial position, and a second opening 413 is provided at one end of the drum assembly 4 close to the vertical portion 32. The bidirectional cleaning assembly 6 includes a screen portion 61 and a solid portion 62. The screen portion 61 is installed on the left side of the inner wall of the cylinder 41, so that when the cylinder 41 rotates, the cat litter in the cylinder 41 can be filtered out of the agglomerated cat litter through the screen portion 61; the solid portion 62 is installed on the left side of the inner wall of the cylinder 41 and connected to the screen portion 61. The solid portion 62 and the inner wall of the cylinder 41 can be enclosed to form a collecting bin 621 and a guide channel 622. The collecting bin 621 is used to collect the screened fine cat litter, and the guide outlet of the guide channel 622 is connected to the second opening 413.

[0090] When in use, the cylinder 41 is rotated forward from the initial position, the fine cat litter will pass through the screen portion 61 and enter the collection bin 621, and the agglomerated cat litter will slide through the screen portion 61 and the solid portion 62 in sequence as the cylinder 41 rotates. After all the agglomerated cat litters have passed through the solid portion 62, the cylinder 41 is rotated reversely, the agglomerated cat litter will slide into the guide channel 622, and in the process of the reverse rotation of the cylinder 41, under the influence of its own gravity, the agglomerated cat litter will be discharged from the cavity 411 from the second opening 413 through the guiding effect of the guide channel 622. After the agglomerated cat litter is completely discharged from the cavity 411, the cylinder 41 is reset to the initial position for normal use.

[0091] When the first opening 412 is facing the user and the drum assembly 4 is in the initial position, a specific description is given by taking the screen portion 61 being located at the lower left side of the drum assembly 4 and the solid portion 62 being located at the upper left side of the drum assembly 4 as an example. When the cylinder 41 rotates counterclockwise by 90°, the cat litter is separated into coarse and fine parts, the fine cat litter passes through the screen portion 61, and the agglomerated cat litter remains on the surface of the screen portion. When the cylinder 41 rotates counterclockwise by 160°, the fine cat litter enters the collecting bin 621, and the agglomerated cat litter slides through the screen portion 61 and the solid portion 62 in turn, and then falls onto the inner wall of the cylinder 41. Finally, the cylinder 41 is rotated clockwise by 160° to return to the initial position. The agglomerated cat litter on the inner wall of the cylinder 41 slides with the rotation of the cylinder 41, and gradually enters the guide channel 622, and is finally discharged from the cavity 411 through the second opening 413.

[0092] It should be noted that, based on the above solution, if the drum assembly 4 at the initial position is rotated 360° clockwise, all cat litter will be discharged from the cavity 411 through the second opening 413 .

[0093] See attached Figure 1 , Attachment Figure 2 and attached Fig.16 Furthermore, a storage box 12 corresponding to the second opening 413 may be provided on the base 1 , so that the agglomerated cat litter cleaned by the two-way cleaning assembly 6 may be directly recovered into the storage box 12 after passing through the second opening 413 .

[0094] See attached Figure 1 , Attachment Figure 2 and attached Fig.17 Furthermore, an automatic sealing and packaging device 13 can be provided above the storage box 12, so that the agglomerated cat litter can first enter the garbage bag after passing through the second opening 413, and the garbage bag can be sealed and packaged before being put into the storage box 12, which can prevent the odor from spreading and soiling the storage box 12.

[0095] See attached Figure 1 and attached Fig. 9 -Attached Fig.11 There are many structures that can clean out the agglomerated cat litter through the unidirectional rotation of the drum assembly 4. One of them is introduced in this embodiment. Specifically, the one-way cleaning assembly 7 includes a storage bin 71, an openable and closable door structure 72, and a cover body 73. The storage bin 71 is installed on the right side of the inner wall of the cylinder 41. The storage bin 71 is hollow inside and has a third opening 711 on the top for storing agglomerated cat litter; the door structure 72 is installed at the third opening 711 on the top of the storage bin 71 to prevent the agglomerated cat litter from emitting odor and escaping from the storage bin 71; the cover body 73 is detachably connected to the cylinder 41 and is arranged corresponding to the storage bin 71, so as to take out the agglomerated cat litter in the storage bin 71.

[0096] When in use, the cylinder 41 is rotated forward from the initial position, and the fine cat litter will pass through the screen portion 61 and enter the collection bin 621. The agglomerated cat litter will slide through the screen portion 61 and the solid portion 62 in sequence as the cylinder 41 rotates. After all the agglomerated cat litters have passed through the solid portion 62, the cylinder continues to be rotated forward, and the agglomerated cat litter will slide along the inner wall of the cylinder 41 and enter the storage bin 71 through the door structure 72. After the agglomerated cat litter has completely entered the storage bin 71, the cylinder 41 is reset to the initial position for normal use.

[0097] When the first opening 412 faces the user and the drum assembly 4 is in the initial position, and the drum assembly 4 has the above-mentioned two-way cleaning assembly 6, a specific description is given by taking the storage bin 71 located in the middle of the right side of the drum assembly 4 as an example. When the drum body 41 rotates 90° counterclockwise, the cat litter is separated into coarse and fine, and the fine cat litter passes through the screen part 61, and the agglomerated cat litter remains on the surface of the screen part. When the drum body 41 rotates 180° counterclockwise, the fine cat litter enters the collection bin 621, and the agglomerated cat litter remains on the surface of the screen part. The cat litter will slide through the screen part 61 and the solid part 62 in turn, and then fall onto the inner wall of the cylinder 41. Then the cylinder 41 will continue to rotate counterclockwise 180° to return to its initial position. The agglomerated cat litter on the inner wall of the cylinder 41 will enter the storage bin 71 as the cylinder 41 rotates counterclockwise. The screened fine cat litter will also return to its original position. At this time, the door structure 72 is closed to prevent the spread of odor. When there is a lot of agglomerated cat litter in the storage bin 71, the cover 73 can also be opened to clean the storage bin 71.

[0098] It should be noted that the rotation angle in the above solution is only one of multiple options. Under the premise that the rotation direction remains unchanged, as long as the above requirements are met, the function of cleaning cat litter can be achieved regardless of the clockwise or counterclockwise rotation angle.

[0099] Furthermore, a garbage bag may be provided in the storage bin 71 so that the agglomerated cat litter can directly enter the garbage bag after passing through the door structure 72, thereby preventing the storage bin 71 from being soiled and eliminating the need for frequent alignment for cleaning.

[0100] Furthermore, the specific structures of the two-way cleaning component and the one-way cleaning component are not limited in the present application and can be flexibly selected according to actual needs. One of the structures is introduced in this embodiment. The structure in the one-way cleaning component 7 is arranged on the left side when the cylinder 41 is in the initial position and is connected to the solid part 62. The cleaning of the agglomerated cat litter can also be achieved by the reciprocating rotation of the cylinder 41. Specifically, the cylinder 41 is first rotated counterclockwise until the agglomerated cat litter slides through the screen part 61, the solid part 62, and the storage bin 71 in sequence. After the agglomerated cat litter completely falls to the inner wall of the cylinder 41, the cylinder 41 is rotated clockwise and returned to its initial position, and the agglomerated cat litter can be collected in the storage bin 71.

[0101] See attached Fig.11and attached Fig.13 -Attached Fig.15 In order to prevent the agglomerated cat litter in the storage bin 71 from spreading odor when the cylinder 41 is in the initial position, and to prevent the agglomerated cat litter in the storage bin 71 from escaping from the storage bin 71 during the rotation of the cylinder 41, the following design is made in this embodiment. Specifically, the door structure 72 includes a frame 721, a first door 722, and a second door 723. The frame 721 is installed at the third opening 711 at the top of the storage bin 71. When the drum is in the initial state, the top of the first door 722 is rotated to connect to the frame 721, and The third opening 711 is closed under the action of gravity to prevent the agglomerated cat litter in the storage bin 71 from emitting odor to the outside; when the drum is in the initial state, the bottom of the second door 723 rotates to connect to the frame 721, and when the second door 723 moves to the left side of the drum, the second door 723 can close the third opening 711 under gravity to prevent the agglomerated cat litter in the storage bin 71 from escaping from the storage bin 71, and when the second door 723 moves to the right side of the drum, both the second door 723 and the first door 722 can be opened to allow the agglomerated cat litter that continuously slides on the inner wall of the cylinder 41 to enter the storage bin 71.

[0102] Furthermore, the entrance of the frame 721 can be designed as a flared structure, so that when the first door 721 and the second door 722 are not opened, the agglomerated cat litter can first accumulate at the entrance of the frame 721 to prevent the agglomerated cat litter from sliding onto the outer wall of the storage bin 71 as the cylinder 41 rotates.

[0103] Furthermore, in order to operate the drum cat litter box more conveniently, a display screen, operation buttons, a controller and other components may be provided on the base 1, and the various electrical components in the drum cat litter box may be controlled by the operation buttons and the controller, and relevant data may be observed through the display screen; the above components are all prior art and will not be described in detail here.
