In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions, and the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature includes the first feature being directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0048] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0050] Traditional pet toilets are directly connected to the outside world, and pet feces cannot be promptly removed, resulting in the emission of foul odors. Existing technologies offer pet toilets that can promptly dispose of feces. After the pet uses the toilet, a vibrating or stirring device separates the litter or cat litter mixed with pet feces and places it into a trash bag. The bag is then closed to reduce odor emissions. However, existing devices require the user to manually seal the trash bag after each use, resulting in a poor user experience. Furthermore, the bag is not tightly sealed, allowing a small amount of odor to escape.

[0051] In this regard, this embodiment provides an excrement collection box, which can also close the collection bag and solve the above-mentioned problem.

[0052] like Figure 1-Figure 3 As shown, the present invention provides a feces collection box for collecting pet feces, and the feces collection box includes a shell 51, a packing assembly and a collection bag 6. The shell 51 is provided with an opening. The packing assembly includes a first slide bar 84, a second slide bar 85 and a hot-melt cutting piece 9, the first slide bar 84 and the second slide bar 85 are arranged at an angle, the first slide bar 84 and the second slide bar 85 can be slidably set on the shell 51, the first slide bar 84 and the second slide bar 85 can both slide toward the hot-melt cutting piece 9 or slide away from the hot-melt cutting piece 9 at the same time, the hot-melt cutting piece 9 is fixedly connected to the shell 51, the collection bag 6 passes through the opening and is connected to the shell 51, the collection bag 6 can be abutted by the first slide bar 84, the second slide bar 85 and the hot-melt cutting piece 9, and the hot-melt cutting piece 9 is configured to be able to seal and cut the collection bag 6.

[0053] Specifically, the first slide bar 84 and the second slide bar 85 gradually shrink the collection bag 6 while sliding toward the hot melt cutting piece 9 until the collection bag 6 is pressed onto the hot melt cutting piece 9. The hot melt cutting piece 9 heats the collection bag 6. Under the action of pressure, the collection bag 6 is hot-melted to achieve sealing to avoid the emission of odor. At the same time, the hot melt cutting piece 9 cuts the sealed collection bag 6 to separate it from the new collection bag 6. This ensures that the collection bag 6 is reliably sealed, and the user does not need to perform the sealing operation on the garbage bag. While improving the user experience, it can also avoid the problem of odor leakage due to loose sealing.

[0054] Optionally, the hot melt cutting member 9 includes a heating element and a cutting element. The heating element heats the collecting bag 6 and, under pressure, causes the collecting bag 6 to be hot-melt sealed. The cutting element cuts the hot-melt sealed collecting bag 6, causing the sealed collecting bag 6 to fall. The heating element and the cutting element in this embodiment can be integrated, for example, the cutting element is arranged along the length direction of the heating element, and the cutting element is arranged in the middle position of the heating element, and the cutting element is provided with a tip or a cutting edge. During the process of hot-melting the collecting bag 6 by the heating element, stress is concentrated at the tip or the cutting edge of the cutting element, and the hot-melted collecting bag 6 is separated under the action of the cutting element.

[0055] Furthermore, if Figure 2-Figure 3 As shown. The packaging assembly also includes a packaging motor 81, a first pulley, a first synchronous belt 822, a second pulley, and a second synchronous belt 832. The packaging motor 81 is fixedly connected to the housing 51. The first and second pulleys are distributed along the length of the motor shaft of the packaging motor 81 and are both fixedly connected to the motor shaft of the packaging motor 81. The first synchronous belt 822 engages with the first pulley, and the second synchronous belt 832 engages with the second pulley. The first and second synchronous belts 822, 832 are arranged at an angle. In this embodiment, the first and second synchronous belts 822, 832 are preferably perpendicular to each other. The first synchronous belt 822 is driven by the first pulley, and the second synchronous belt 832 is driven by the second pulley. The ends of the first and second synchronous belts 822, 832 away from the packaging motor 81 are also connected to the first and second pulleys to ensure reliable operation of the first and second synchronous belts 822, 832. The first and second sliding rods 84, 85 are respectively connected to the first and second synchronous belts 822, 832.

[0056] Furthermore, the first slide bar 84 is provided with a first drive block 841, and the second slide bar 85 is provided with a second drive block 851. The first drive block 841 is fixedly connected to the first synchronous belt 822, and the second drive block 851 is fixedly connected to the second synchronous belt 832. The first drive block 841 preferably engages with the first synchronous belt 822, and the second drive block 851 preferably engages with the second synchronous belt 832.

[0057] It should be noted that, in this embodiment, the hot melt cutting piece 9 is arranged at one of the corners of the opening, and the packing motor 81 is arranged at the corresponding corner on the shell 51, and the packing motor 81 is arranged in the vertical direction. Therefore, the first pulley and the second pulley are also arranged in the vertical direction, and the corresponding first synchronous belt 822 and second synchronous belt 832 have belt teeth in the horizontal direction. To ensure that the first slide bar 84 and the second slide bar 85 can move toward or away from the hot melt cutting piece 9 at the same time. In this embodiment, the first drive block 841 of the first slide bar 84 is fixedly connected to the side of the first synchronous belt 822 close to the collection bag 6, and the second drive block 851 of the second slide bar 85 is fixedly connected to the side of the second synchronous belt 832 away from the collection bag 6. Figure 2 For example, the packaging motor 81 rotates clockwise, driving the first and second pulleys to rotate clockwise, and then driving the first synchronous belt 822 and the second synchronous belt 832 to rotate clockwise. The corresponding first synchronous belt 822 moves toward the hot melt cutting piece 9 on the side close to the collection bag 6, and the second synchronous belt 832 moves toward the hot melt cutting piece 9 on the side away from the collection bag 6. Therefore, the first slide bar 84 and the second slide bar 85 can move toward the hot melt cutting piece 9 at the same time. It can be understood that in Figure 2 From the perspective of , the counterclockwise rotation of the packaging motor 81 can achieve the simultaneous movement of the first slide bar 84 and the second slide bar 85 away from the hot melt cutting piece 9. In other embodiments, the first driving block 841 of the first slide bar 84 can be fixedly connected to the side of the first synchronous belt 822 away from the collection bag 6, and the second driving block 851 of the second slide bar 85 can be fixedly connected to the side of the second synchronous belt 832 close to the collection bag 6. By adjusting the rotation direction of the packaging motor 81 accordingly, the first slide bar 84 and the second slide bar 85 can also be achieved. Move toward or away from the hot melt cutting piece 9 at the same time. The relevant implementation principle has been described in detail above. The principles of the two are the same, so they will not be repeated here.

[0058] Optionally, the packing assembly is further provided with a motor box 811, a first pulley box 821, and a second pulley box 831. The packing motor 81 and the first pulley and the second pulley fixedly provided on the motor shaft are all provided in the motor box 811, and the first synchronous belt 822 and the second synchronous belt 832 pass through the motor box 811. The first pulley at the other end of the first synchronous belt 822 is provided in the first pulley box 821, and the first synchronous belt 822 passes through the first pulley box 821. The second pulley at the other end of the second synchronous belt 832 is provided in the second pulley box 831, and the second synchronous belt 832 passes through the second pulley box 831. To ensure the movement accuracy of the first sliding rod 84 and the second sliding rod 85, a first guide support shaft 823 is fixedly connected between the motor box 811 and the first pulley box 821, and a second guide support shaft 833 is fixedly connected between the motor box 811 and the second pulley box 831. The first driving block 841 is sleeved on the first guide support shaft 823 and is slidably connected to the first guide support shaft 823. The second driving block 851 is sleeved on the second guide support shaft 833 and is slidably connected to the second guide support shaft 833. The movement direction of the first guide support shaft 823 is parallel to that of the first driving block 841, and the movement direction of the second guide support shaft 833 is parallel to that of the second driving block 851.

[0059] Furthermore, in order to ensure transmission accuracy, the first slide bar 84 and the second slide bar 85 are preferably arranged perpendicular to each other. The first synchronous belt 822 and the first slide bar 84 are arranged perpendicular to each other, and the second synchronous belt 832 and the second slide bar 85 are arranged perpendicular to each other. The first drive block 841 is arranged at one end of the first slide bar 84 and is slidably connected to the first guide support shaft 823, and the second drive block 851 is arranged at one end of the second slide bar 85 and is slidably connected to the second guide support shaft 833. Since the first guide support shaft 823 has already provided sufficient support for the first drive block 841 and the first slide bar 84, the other end of the first slide bar 84 where the first drive block 841 is not provided can be suspended, or can be slidably connected to the housing 51 to further strengthen the support. Those skilled in the art can choose as needed, and the specific structure is not limited here. Since the second guide support shaft 833 has provided sufficient support for the second drive block 851 and the second slide rod 85, the other end of the second slide rod 85 where the second drive block 851 is not provided can be suspended in the air, or can be slidably connected to the shell 51 to further strengthen the support. Technical personnel in this field can choose as needed, and the specific structure is not limited here.

[0060] Specifically, when the first and second slide rods 84, 85 simultaneously move toward or away from the hot melt cutting element 9, since the first and second slide rods 84, 85 are driven by the first and second pulleys, respectively, and the first and second pulleys have the same rotational speed, considering the problem of inconsistent stroke lengths of the first and second slide rods 84, 85, to ensure that the first and second slide rods 84, 85 can simultaneously abut the hot melt cutting element 9, the number of teeth on the first and second pulleys can be determined based on the strokes of the first and second slide rods 84, 85. For ease of understanding, specific numerical values are used in this embodiment for analysis, but they are not intended to be limiting. Assuming that the stroke of the second slide rod 85 is twice that of the first slide rod 84, the stroke of the first slide rod 84 is a, and the stroke of the second slide rod 85 is 2a. Since both the first and second pulleys are fixedly connected to the motor shaft, their rotational speeds are equal. The teeth of the first pulley mesh with the first synchronous belt 822, and the teeth of the second pulley mesh with the second synchronous belt 832. Therefore, the number of teeth of the second pulley is set to be twice the number of teeth of the first pulley. In this way, under the premise that the number of teeth of the first and second synchronous belts 822 and 832 is the same, the motor shaft can rotate a certain angle, and the distance traveled by the second synchronous belt 832 is twice the distance traveled by the first synchronous belt 822. This ensures that the first slide bar 84 and the second slide bar 85 can simultaneously abut against the hot-melt cutting member 9 even when their travel distances are different.

[0061] Optionally, the feces collection box also includes a collection box 52, which is arranged below the shell 51 and is detachably connected to the shell 51. The inner side wall of the collection box 52, the bottom wall of the shell 51 and the outer bottom wall of the collection bag 6 together form a negative pressure space. A negative pressure device 53 is fixedly connected to the collection box 52, and the negative pressure device 53 is configured to apply negative pressure to the negative pressure space. After the hot melt cutting piece 9 performs hot melt cutting on the collection bag 6. The collection bag 6 is hot-melt sealed at the position of the hot melt cutting piece 9. After cutting, a part of the hot-melt sealed collection bag 6 falls off with the cutting, and the other part of the hot-melt sealed collection bag 6 serves as the bottom of a new collection bag 6. After the negative pressure device 53 applies negative pressure, due to the effect of atmospheric pressure, the new collection bag 6 expands toward the inner side wall of the collection box 52, thereby completing the arrangement of the new collection bag 6. The negative pressure device 53 in this embodiment is preferably a fan, and the blowing direction of the fan is toward the outside of the collection box 52.

[0062] Optionally, the housing 51 is provided with a sealing position sensor 73 and a standby position sensor 74. The packaging assembly has a sealing state and a standby state. When the packaging assembly is in the sealing state, the collection bag 6 is abutted by the first slide bar 84, the second slide bar 85, and the hot melt cutting element 9, and at least a portion of the first slide bar 84 overlaps with the sealing position sensor 73. When the packaging assembly is in the standby state, at least a portion of the first slide bar 84 overlaps with the standby position sensor 74.

[0063] Furthermore, the sealing position sensor 73 and the standby position sensor 74 in this embodiment can both be Hall sensors, proximity switches, or infrared sensors. In this embodiment, the sealing position sensor 73 and the standby position sensor 74 are preferably Hall sensors. It should be noted that in other embodiments, the open position sensor 71 and the closed position sensor 72 can also be set as different types of sensors, such as the open position sensor 71 being set as a Hall sensor and the closed position sensor 72 being set as a proximity switch. Specific arrangements are not exhaustive here. In this embodiment, to further enhance the sensitivity of the sealing position Hall sensor and the standby position Hall sensor, a second magnet 842 is provided on the first slide bar 84. When the packaging assembly is in the sealing state, the second magnet 842 is located above the sealing position Hall sensor. When the packaging assembly is in the standby state, the second magnet 842 is located above the standby position Hall sensor. Both the sealing position Hall sensor and the standby position Hall sensor are communicatively connected to the processor, and the processor is fixedly connected to the housing 51.

[0064] Optionally, a detection sensor and a prompting device may be provided in the collection box 52. The detection sensor is communicatively connected to the processor. After the cut collection bag 6 falls into the collection box 52, the detection sensor detects the presence of the collection bag 6. If the cut collection bag 6 is not removed from the collection box 52, the new collection bag 6 may not be deployed or the deployment may be unsatisfactory. The detection sensor can detect whether there are any unremoved collection bags 6 in the collection box 52. After confirming that there are no unremoved collection bags 6 in the collection box 52, the negative pressure device 53 is activated to deploy a new collection bag 6. The detection sensor can be any type of sensor with a detection function, such as an infrared sensor, a proximity switch, an accelerometer, a weight sensor, etc. The detection sensor can be positioned anywhere within the collection box 52 based on its function and detection principle. Multiple detection sensors can be provided as needed to enhance detection accuracy. If a weight sensor is used, multiple weight sensors can be evenly distributed at the bottom of the collection box 52. When one or more weight sensors sense a weight change reaching a preset value, it indicates that the collection bag 6 has fallen into the collection box 52. At this time, the processor controls a prompting device communicatively connected thereto to prompt the user to remove the collection bag 6 promptly. At this point, the user can remove the collection box 52 and take out the packed collection bag 6 from the collection box 52, then reconnect the collection box 52 to the housing 51. For ease of operation, a buckle can be used to achieve a detachable connection between the collection box 52 and the housing 51. The structure of the buckle and the principle of using the buckle to achieve a detachable connection are mature existing technologies in this field and are not described in detail here. The prompt device can be one or both of a warning light and a horn. Using a processor to control the prompt device to provide a prompt is a mature existing technology in this field and is not described in detail here. After the detection sensor detects that the collection bag 6 has been removed, the processor controls the fan to exhaust air, and under the action of atmospheric pressure, a new collection bag 6 is sucked in and unfolded.

[0065] In this embodiment, the processor can be a centralized or distributed controller. For example, the processor can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The single-chip microcomputer can run a control program to control each component to realize its function.

[0066] Alternatively, as Figure 4-11As shown, the feces collection box also includes a sealing assembly and a detection unit. The sealing assembly includes a left sealing portion 11 and a right sealing portion 21. The left sealing portion 11 and / or the right sealing portion 21 can slide relative to the shell 51. The left sealing portion 11 is configured to be closed with the right sealing portion 21. The collection bag 6 is connected to the shell 51. The outer side wall of the collection bag 6 can be abutted by the sealing assembly. The detection unit is rotatably arranged on at least one of the left sealing portion 11 and the right sealing portion 21. The detection unit can be rotated toward the bottom wall of the collection bag 6. When the collection bag 6 is full, the detection unit can abut against the pet feces. After the left sealing portion 11 abuts the right sealing portion 21, the collection bag 6 is sealed by the sealing assembly to prevent the release of odor. During the process of the sealing assembly sealing the collection bag 6, the state of the detection unit can be used to determine whether the collection is full. When the collection is not full, the detection unit can rotate normally toward the bottom wall of the collection bag 6 until the collection bag 6 is sealed. When the collection is full, the detection unit cannot rotate toward the bottom wall of the collection bag 6 or the rotation is blocked. The user can replace the collection bag 6 accordingly, thereby saving the collection bag 6 and reducing the frequency of user cleaning while preventing the release of odor. After detecting that the collection bag 6 is full, the packaging assembly performs hot-melt sealing, cutting, and unfolding of the full collection bag 6 to reduce user operations.

[0067] Specifically, the left side sealing portion 11 and the right side sealing portion 21 can be relatively close to or relatively far away from each other. The detection unit is rotatably arranged on at least one of the left side sealing portion 11 and the right side sealing portion 21. In the present embodiment, it is preferred that both the left side sealing portion 11 and the right side sealing portion 21 are rotatably provided with a detection unit. The detection unit includes a left side rotating shaft 112, a left side detection member 12, a right side rotating shaft 212 and a right side detection member 22. The left side detection member 12 is rotationally connected to the left side sealing portion 11 via the left side rotating shaft 112, and the right side detection member 22 is rotationally connected to the right side sealing portion 21 via the right side rotating shaft 212. During the process of the left side sealing portion 11 and the right side sealing portion 21 approaching each other, the left side detection member 12 and the right side detection member 22 both slide relative to the housing 51 and the length extending out of the housing 51 increases. During the process of the left side sealing portion 11 and the right side sealing portion 21 moving away from each other, the left side detection member 12 and the right side detection member 22 both slide relative to the housing 51 and the length extending out of the housing 51 decreases. Both the left sealing portion 11 and the right sealing portion 21 are provided with limiters to prevent the left sealing portion 11 and the right sealing portion 21 from exceeding the closed position during relative movement. Those skilled in the art may configure limiters to restrict the position of components based on practical engineering requirements; the specific structure is not specifically defined herein.

[0068] Furthermore, when the left sealing portion 11 and the right sealing portion 21 are relatively close, the left detection member 12 and the right detection member 22 can both rotate toward the bottom wall of the collection bag 6. When the left sealing portion 11 and the right sealing portion 21 are relatively close, since the length of the left detection member 12 and the right detection member 22 extending out of the shell 51 increases, the left detection member 12 and the right detection member 22 can rotate toward the bottom wall of the collection bag 6 by their own gravity or by adding a torsion spring at the rotating shaft. When the left sealing portion 11 and the right sealing portion 21 are relatively far apart, the length of the left detection member 12 and the right detection member 22 extending out of the shell 51 decreases, and under the reaction force of the shell 51, the left detection member 12 and the right detection member 22 both rotate in the direction opposite to the bottom wall of the collection bag 6.

[0069] Furthermore, when the feces collection box is not full, both the left detection member 12 and the right detection member 22 can rotate normally toward the bottom wall of the collection bag 6, and the left sealing portion 11 and the right sealing portion 21 can close normally, and the closed position is located in the middle of the two. In actual use scenarios, when the feces collection box is full, the pet feces accumulation heights at different positions in the collection bag 6 are uneven, and it is possible that one of the left detection member 12 and the right detection member 22 is blocked from rotating toward the bottom wall of the collection bag 6 while the other can rotate normally. At this time, one of the left sealing portion 11 and the right sealing portion 21 cannot continue to move or the movement speed slows down, while the other can move normally. The provision of the upper limit members on the left sealing portion 11 and the right sealing portion 21 ensures that when the above situation occurs, it can ensure that the left sealing portion 11 or the right sealing portion 21 stops after reaching the closed position first and does not exceed the closed position. This makes it easy to judge whether the collection is full, and it can also avoid sealing failure and prevent the spread of odor.

[0070] It is understandable that when using collection bags 6 of different specifications for collection, there are certain differences in the height of the excrement that can be stored inside the collection bag 6. To this end, the left detection member 12 and the right detection member 22 can be set to different lengths to effectively detect whether the collection is full. Specifically, when the height of the excrement that can be stored in the collection bag 6 is high, the length of the left detection member 12 and the right detection member 22 is reduced to maximize the use of the space in the collection bag 6. Conversely, when the height of the excrement that can be stored in the collection bag 6 is low, the length of the left detection member 12 and the right detection member 22 is increased to avoid the situation where the collection bag 6 cannot be sealed and packaged smoothly.

[0071] Specifically, the left sealing part 11 and the right sealing part 21 are driven by a drive transmission assembly. The drive transmission assembly is fixedly arranged on the housing 51. The drive transmission assembly includes a drive unit 31, an intermediate gear 32 and a transmission unit. The drive unit 31 is fixedly connected to the housing 51. The drive unit 31 can be a servo motor or a stepper motor, preferably a servo motor. The drive unit 31 is provided with a drive gear shaft 311, and the drive gear shaft 311 is engaged with the intermediate gear 32. The intermediate gear 32 is sleeved on the output shaft 33. The connection method between the intermediate gear 32 and the output shaft 33 is preferably a key connection. The output shaft 33 is rotationally connected to the housing 51. At least one end of the output shaft 33 is transmission-connected to the transmission unit.

[0072] Furthermore, the transmission unit includes a third pulley 34 and a third synchronous belt 41. The third pulley 34 is mounted on the output shaft 33. The connection between the third pulley 34 and the output shaft 33 is preferably a keyed connection. The third synchronous belt 41 engages with the third pulley 34. A left drive block 111 is provided at the end of the left sealing portion 11, and a right drive block 211 is provided at the end of the right sealing portion 21. Both the left drive block 111 and the right drive block 211 are fixedly connected to the third synchronous belt 41. This allows the left sealing portion 11 and the right sealing portion 21 to move relatively closer or farther apart. In this embodiment, the left drive block 111 is fixedly connected to the upper portion of the third synchronous belt 41, while the right drive block 211 is fixedly connected to the lower portion of the third synchronous belt 41. When the third synchronous belt 41 rotates clockwise, the left drive block 111 and the right drive block 211 move relatively closer or farther apart, thereby driving the left sealing portion 11 and the right sealing portion 21 to move relatively closer or farther apart. When the third synchronous belt 41 rotates counterclockwise, the left driving block 111 and the right driving block 211 move relatively away from or closer to each other, thereby driving the left sealing portion 11 and the right sealing portion 21 to move relatively away from or closer to each other.

[0073] In other embodiments of the present invention, the left drive block 111 can be fixedly connected to the bottom of the third synchronous belt 41, while the right drive block 211 is fixedly connected to the top of the third synchronous belt 41. This can also achieve relative proximity or distance between the left drive block 111 and the right drive block 211. The specific implementation principle has been described in detail above and will not be repeated here.

[0074] Furthermore, to achieve a better connection, in this embodiment, both the left drive block 111 and the right drive block 211 are provided with an engaging portion and a limiting portion, which are fixedly connected. The engaging portion is provided with engaging teeth, which are configured to engage with the teeth of the third synchronous belt 41 and be driven by the teeth of the third synchronous belt 41. The limiting portion is disposed on the outside of the third synchronous belt 41 and is configured to prevent the third synchronous belt 41 from jumping during transmission. The provision of the limiting portion prevents the third synchronous belt 41 from jumping during transmission, which could cause the teeth of the third synchronous belt 41 to disengage from the engaging portion, leading to transmission failure.

[0075] Furthermore, to prevent relative offset between the left and right drive blocks 111, 211 during their relative approach or separation, the transmission unit further includes a third guide support shaft 42, which is fixedly mounted on the housing 51. The third guide support shaft 42 is arranged parallel to the direction of movement of the left and right drive blocks 111, 211, and both the left and right drive blocks 111, 211 are sleeved on the third guide support shaft 42 and are slidably connected thereto.

[0076] Alternatively, as Figure 4-Figure 5 As shown, to ensure uniform loading on the left and right sealing portions 11 and 21, two transmission units are provided in this embodiment, each of which is in transmission connection with the ends of the output shaft 33. Accordingly, two left drive blocks 111 and two right drive blocks 211 are each provided. The two left drive blocks 111 are located at either end of the left sealing portion 11, and the two right drive blocks 211 are located at either end of the right sealing portion 21. Since this embodiment has already described in detail the connection between the output shaft 33 and the transmission units, the components of the transmission units, and the connection between the transmission units and the left and right drive blocks 111 and 211, and has also specifically analyzed how the left and right drive blocks 111 and 211 can move toward or away from each other, the above details will not be repeated here. The arrangement of the output shaft 33, the third pulley 34, and the third synchronous belt 41 ensures consistent movement of the two ends of the output shaft 33, thereby ensuring the reliability of the movement of the left and right sealing portions 11 and 21 during relative approach or separation.

[0077] Alternatively, as Figure 6As shown, to enhance the sealing effect of the sealing assembly on the collection bag 6, a sealing strip 113 is fixedly mounted on the left sealing portion 11 or the right sealing portion 21. In this embodiment, the sealing strip 113 is mounted on the side of the left sealing portion 11 facing the right sealing portion 21. In other embodiments, the sealing strip 113 may also be mounted on the side of the right sealing portion 21 facing the left sealing portion 11. When the left sealing portion 11 and the right sealing portion 21 abut, the sealing strip 113 abuts the outer wall of the collection bag 6. The sealing effect of the sealing assembly on the collection bag 6 is ensured by the creep deformation of the sealing strip 113 when the left sealing portion 11 and the right sealing portion 21 abut. Those skilled in the art may also enhance the sealing effect of the sealing assembly on the collection bag 6 through other methods. For example, a protrusion may be provided on the side of one of the left sealing portion 11 and the right sealing portion 21 facing the other. Correspondingly, a groove may be provided on the other of the left sealing portion 11 and the right sealing portion 21 to mate with the protrusion. When the left sealing portion 11 and the right sealing portion 21 are in contact, the protrusion cooperates with the groove to enhance the sealing effect on the collection bag 6 by utilizing the principle of labyrinth sealing.

[0078] Alternatively, as Figure 4-Figure 5 As shown, it is convenient for the user to know whether the feces collection box is full. The shell 51 is also provided with an open position sensor 71 and a closed position sensor 72, and the sealing assembly has an open state and a closed state. When the sealing assembly is in the open state, at least a portion of the sealing assembly overlaps with the open position sensor 71. When the sealing assembly is in the closed state, the left sealing portion 11 and the right sealing portion 21 abut against each other, and at least a portion of the sealing assembly overlaps with the closed position sensor 72. When the feces collection box is full, the pet excrement capacity in the collection bag 6 is relatively large. In the process of the sealing assembly sealing the collection bag 6, the left detection member 12 and the right detection member 22 are affected by the pet excrement and cannot continue to rotate toward the bottom wall of the collection bag 6, resulting in the sealing assembly being unable to seal the collection bag 6, that is, at least a portion of the sealing assembly cannot overlap with the closed position sensor 72. Furthermore, due to the particularity of the usage scenario, under certain specific conditions, even if the collection bag 6 is full of feces, the rotation of the left detection member 12 and / or the right detection member 22 toward the bottom wall of the collection bag 6 is blocked, but at this time the drive unit 31 is still driving the sealing assembly. Under the action of the driving force, the left detection member 12 and / or the right detection member 22 can squeeze the feces and continue to rotate toward the bottom wall of the collection bag 6. That is to say, the sealing assembly can be in a closed state under the action of the driving force. It is understandable that the time required for the sealing assembly to be in a closed state in this usage scenario is also longer. Therefore, it is possible to determine whether the collection is full by presetting the closing time. When the sealing assembly is not able to be in a closed state within the first preset time, it proves that the collection is full at this time, so as to facilitate subsequent operations.

[0079] Furthermore, the open position sensor 71 and the closed position sensor 72 in this embodiment can both be Hall effect sensors, proximity switches, or infrared sensors. In this embodiment, both the open position sensor 71 and the closed position sensor 72 are preferably Hall effect sensors. It should be noted that in other embodiments, the open position sensor 71 and the closed position sensor 72 can also be configured as different types of sensors, such as configuring the open position sensor 71 as a Hall effect sensor and the closed position sensor 72 as a proximity switch. Specific arrangements are not exhaustive here. In this embodiment, to further enhance the sensitivity of the open position Hall effect sensor and the closed position Hall effect sensor, a first magnet 114 is provided on either the left sealing portion 11 or the right sealing portion 21. When the sealing assembly is in the open state, the first magnet 114 is positioned above the open position Hall effect sensor. When the sealing assembly is in the closed state, the first magnet 114 is positioned above the closed position Hall effect sensor. Both the open position Hall effect sensor and the closed position Hall effect sensor are communicatively connected to a processor, which is fixedly connected to the housing 51.

[0080] Specifically, during the process of the sealing assembly sealing the collection bag 6, the drive unit 31 is driven in the forward direction, the drive gear shaft 311 engages with the intermediate gear 32, the intermediate gear 32 drives the output shaft 33 to rotate, the output shaft 33 drives the third pulley 34 set at both ends of the output shaft 33 to rotate, and the third pulley 34 drives the third synchronous belt 41 to transmit. The left drive block 111 and the right drive block 21 engage with the bottom and top of the third synchronous belt 41 respectively and drive the left sealing portion 11 and the right sealing portion 21 to move relatively close. At this time, if the collection bag 6 is not full, the left detection member 12 and the right detection member 22 can both rotate toward the bottom wall of the collection bag 6, and the left sealing portion 11 can close with the right sealing portion 21. At this time, if the collection bag 6 is full, the left detection member 12 and the right detection member 22 are blocked from rotating toward the bottom wall of the collection bag 6, and the left sealing portion 11 cannot close with the right sealing portion 21. At this time, the collection bag 6 is full. The processor controls the operation of the packaging motor 81, driving the first and second slides 84, 85 toward the hot-melt cutting element 9. When the first and second slides 84, 85 abut the hot-melt cutting element 9, the second magnet 842 on the first slide 84 is positioned above the sealing position Hall effect sensor. The hot-melt cutting element 9 performs heat-melt sealing on the collection bag 6. During this process, the packaging motor 81 continuously outputs power to ensure that the first and second slides 84, 85, and the hot-melt cutting element 9 remain in contact with the collection bag 6, ensuring the effectiveness of the heat-melt sealing process. After a second preset time, the hot-melt cutting element 9 stops heating, and the packaging motor 81 simultaneously drives the first and second slides 84, 85 away from the hot-melt cutting element 9. When the second magnet 842 on the first slide 84 is positioned above the standby position Hall effect sensor, the packaging motor 81 stops and, through control of the processor, a notification device in communication with it prompts the user to remove the collection bag 6 immediately. The notification device may be one or both of a warning light and a horn. The use of a processor to control the prompt device to prompt belongs to the mature existing technology in this field and will not be described in detail here. After the detection sensor detects that the collection bag 6 is taken out, the processor controls the fan to exhaust air, and under the action of atmospheric pressure, a new collection bag 6 is sucked in and unfolded.

[0081] In this embodiment, the processor can be a centralized or distributed controller. For example, the processor can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The single-chip microcomputer can run a control program to control each component to realize its function.

[0082] This embodiment provides a method for using a feces collection box, which uses the feces collection box provided in the embodiment of the present invention.

[0083] like Figure 12 As shown, the full set detection method includes:

[0084] S1. The driving unit 31 drives forward, and the first magnet 114 of at least part of the sealing assembly leaves the upper portion of the Hall sensor at the open position. The processor receives a leaving signal and drives the sealing assembly to move at a first preset time.

[0085] S2. If the first magnet 114 of at least a portion of the sealing assembly reaches above the Hall sensor of the closed position within the first preset time, and the processor receives an arrival signal within the first preset time, then the feces collection box is not full, and the processor controls the driving unit 31 to stop, and the sealing assembly is in the closed state;

[0086] S3. If the sealing assembly does not reach above the closed position Hall sensor of the closed position sensor 72 within the first preset time, and the processor does not receive an arrival signal within the first preset time, the feces collecting box is full.

[0087] Furthermore, when the feces collecting box is full, the processor controls the driving unit 31 to drive in reverse to return the sealing assembly to the open state, and then performs the packaging and sealing operation. Figure 13 As shown, the packaging and sealing operation method is as follows:

[0088] S31, the processor controls the packing motor 81 to rotate forward, and the packing motor 81 drives the first slide bar 84 and the second slide bar 85 to move toward the hot melt cutting piece 9;

[0089] S32, the first slide bar 84 and the second slide bar 85 are in place, and the second magnet 842 reaches above the sealing position Hall sensor. The sealing position Hall sensor collects a signal and transmits it to the processor, which starts timing. The processor controls the hot melt cutting piece 9 to hot melt seal and cut the collection bag 6. During this process, the packaging motor 81 continues to output power to the outside.

[0090] S33: The collection bag 6 falls into the collection box 52. After the processor reaches the second preset time, the processor controls the packing motor 81 to reverse, and the packing motor 81 drives the first slide bar 84 and the second slide bar 85 to move away from the hot-melt cutting piece 9. The second magnet 842 reaches above the Hall sensor at the standby position. The Hall sensor at the standby position collects a signal and transmits it to the processor, and the processor controls the packing motor 81 to stop.

[0091] S34, the detection sensor detects whether the collection bag 6 in the collection box 52 is taken out, if not, a prompt is given; if yes, the negative pressure device 53 is started to draw out and unfold a new collection bag 6.

[0092] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
