[0009] In the description of the present application, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is merely for facilitating the description of the present application and simplifying the description, and does not indicate or imply that such a device or element must have a specific orientation and must be configured and operated in a specific orientation. Therefore, it cannot be understood as limiting the present application. Also, the terms "first" and "second" are merely for the purpose of description and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions. Further, the fact that the first feature is "above", "upper" and "upper surface" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The fact that the first feature is "below", "lower" and "lower surface" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is smaller than that of the second feature.

[0010] In the description of the present application, unless otherwise specifically defined or limited, the terms "attach", "connect", and "couple" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection, and may be a mechanical connection, an electrical connection, directly connected, indirectly connected through an intermediate medium, or a communication inside two elements. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0011] Hereinafter, embodiments of the present application will be described in detail. The examples of the above embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. Hereinafter, the embodiments described with reference to the drawings are exemplary only and are merely for interpreting the present application and should not be construed as limiting the present application.

[0012] In related technologies, the pet toilet is directly connected to the outside, and since pet feces cannot be removed in a timely manner, the odor will spread. In related technologies, after the pet finishes using the toilet, a vibrating device or a stirring device is used to separate the bedding or cat litter mixed with pet feces and discharge it into a garbage bag, and the garbage bag is closed to reduce the spread of the odor, providing a pet toilet that can process feces in a timely manner. However, for the device according to related technologies, every time the pet finishes using the toilet, the user has to face the garbage bag and manually seal it, resulting in a poor user experience during use, and the sealing of the garbage bag after manual sealing by the user is not sufficient, and still a small amount of odor leaks out.

[0013] In contrast, in this embodiment, a feces collection box that can similarly close the collection bag and simultaneously solve the above problems is provided.

[0014] As shown in FIGS. 1 to 3, in the present application, there is provided a feces collection box provided to collect pet feces, the feces collection box including a housing 51, a packaging assembly, and a collection bag 6. An opening is provided in the housing 51. The packaging assembly includes a first slide bar 84, a second slide bar 85, and a heat melting and cutting material 9. The first slide bar 84 and the second slide bar 85 are installed at an angle. The first slide bar 84 and the second slide bar 85 are respectively slidably provided on the housing 51. The first slide bar 84 and the second slide bar 85 can slide simultaneously towards the heat melting and cutting material 9 or simultaneously away from the heat melting and cutting material 9. The heat melting and cutting material 9 is fixedly connected to the housing 51. The collection bag 6 passes through the opening and is connected to the housing 51. The collection bag 6 can be abutted by the first slide bar 84, the second slide bar 85, and the heat melting and cutting material 9. The heat melting and cutting material 9 is configured to be able to seal and cut the collection bag 6.

[0015] In one embodiment, when the first slide bar 84 and the second slide bar 85 slide simultaneously towards the heat melting and cutting material 9, until the collection bag 6 is pressed against the heat melting and cutting material 9, the collection bag 6 is gradually contracted. The heat melting and cutting material 9 heats the collection bag 6. Under the action of pressure, the collection bag 6 is heat melted to achieve sealing, and the spread of abnormal odors is avoided. At the same time, the heat melting and cutting material 9 cuts the collection bag 6 after sealing and separates it from the new collection bag 6. In this way, reliable sealing of the collection bag 6 is guaranteed. The user does not need to perform a sealing operation facing the garbage bag, the use experience is improved, and at the same time, the problem of odor escape due to poor closure can also be avoided.

[0016] In one embodiment, the thermal fusion cutting member 9 includes a heating element and a cutting member. The heating element heats the collection bag 6 to realize a thermal fusion seal on the collection bag 6 under the action of pressure. The cutting member cuts the collection bag 6 after the thermal fusion seal and causes the sealed collection bag 6 to fall. The heating element and the cutting member in this embodiment may be provided integrally. For example, the cutting member is provided along the longitudinal direction of the heating element, and the cutting member is provided at an intermediate position of the heating element. The cutting member is provided with a tip or a cutting edge. During the process of thermal fusion of the collection bag 6 by the heating element, stress concentrates on the tip or the cutting edge of the cutting member, and the collection bag 6 after being thermally fused is separated by the action of the cutting member.

[0017] In one embodiment, as shown in FIGS. 2 to 3, the packaging assembly further 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 pulley and the second pulley are arranged along the longitudinal direction of the motor shaft of the packaging motor 81 and are respectively fixedly connected to the motor shaft of the packaging motor 81. The first synchronous belt 822 is engaged with the first pulley, and the second synchronous belt 832 is engaged with the second pulley. The first synchronous belt 822 and the second synchronous belt 832 are installed at an angle. In this embodiment, the first synchronous belt 822 and the second synchronous belt 832 are 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. One ends of the first synchronous belt 822 and the second synchronous belt 832 away from the packaging motor 81 are similarly connected to the first pulley and the second pulley so that the first synchronous belt 822 and the second synchronous belt 832 can operate reliably. The first slide bar 84 and the second slide bar 85 are respectively transmission-connected to the first synchronous belt 822 and the second synchronous belt 832.

[0018] In one embodiment, a first drive block 841 is provided on the first slide bar 84, and a second drive block 851 is provided on the second slide bar 85. 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. In one embodiment, the first drive block 841 is engaged with the first synchronous belt 822, and the second drive block 851 is engaged with the second synchronous belt 832.

[0019] In this embodiment, the hot melt cutting material 9 is provided at one of the corners of the opening, and the packaging motor 81 is provided at the corner corresponding to the hot melt cutting material 9 in the housing 51, and the packaging motor 81 is arranged along the vertical direction. Therefore, the first pulley and the second pulley are similarly arranged along the vertical direction, and the axial directions of the first pulley and the second pulley are horizontal. The belt teeth of the corresponding first synchronous belt 822 and second synchronous belt 832 are provided along the horizontal direction. In order to ensure that the first slide bar 84 and the second slide bar 85 can move towards and away from the hot melt cutting material 9 simultaneously, in this embodiment, the first driving block 841 of the first slide bar 84 is fixedly connected to the side close to the collecting bag 6 of the first synchronous belt 822, and the second driving block 851 of the second slide bar 85 is fixedly connected to the side away from the collecting bag 6 of the second synchronous belt 832. Taking the perspective in FIG. 2 as an example, the packaging motor 81 rotates clockwise, drives the first pulley and the second pulley to rotate clockwise in an interlocking manner, and further drives the first synchronous belt 822 and the second synchronous belt 832 to rotate clockwise in an interlocking manner. The side close to the collecting bag 6 of the corresponding first synchronous belt 822 moves towards the hot melt cutting material 9, and the side away from the collecting bag 6 of the second synchronous belt 832 moves towards the hot melt cutting material 9. Therefore, it is realized that the first slide bar 84 and the second slide bar 85 can move towards the hot melt cutting material 9 simultaneously. From the perspective of FIG. 2, when the packaging motor 81 rotates counterclockwise, it is possible to realize that the first slide bar 84 and the second slide bar 85 move away from the hot melt cutting material 9 simultaneously. In other embodiments, the first driving block 841 of the first slide bar 84 is fixedly connected to the side away from the collecting bag 6 of the first synchronous belt 822, and the second driving block 851 of the second slide bar 85 is fixedly connected to the side close to the collecting bag 6 of the second synchronous belt 832. It is also possible to correspondingly adjust the rotation direction of the packaging motor 81. Thereby, it is similarly possible to realize that the first slide bar 84 and the second slide bar 85 move towards and away from the hot melt cutting material 9 simultaneously. The related realization principle has been described in detail in the previous text. Since the principles of the two are the same, it will not be repeated here.

[0020] In one embodiment, the packaging assembly is further provided with a motor box 811, a first pulley box 821, and a second pulley box 831. The packaging motor 81, as well as the first pulley and the second pulley fixedly provided on the motor shaft, are respectively provided in the motor box 811. The first end of the first synchronous belt 822 and the first end of the second synchronous belt 832 pass through the motor box 811. The first pulley at the second end of the first synchronous belt 822 is provided in the first pulley box 821, and the second end of the first synchronous belt 822 passes through the first pulley box 821. The second pulley at the second end of the second synchronous belt 832 is provided in the second pulley box 831, and the second end of the second synchronous belt 832 passes through the second pulley box 831. In order to ensure the movement accuracy of the first slide bar 84 and the second slide bar 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 drive block 841 is fitted onto the first guide support shaft 823 and is slidably connected to the first guide support shaft 823. The second drive block 851 is fitted onto the second guide support shaft 833 and is slidably connected to the second guide support shaft 833. The first guide support shaft 823 is parallel to the movement direction of the first drive block 841, and the second guide support shaft 833 is parallel to the movement direction of the second drive block 851.

[0021] In one embodiment, to ensure the transmission accuracy, the first slide bar 84 and the second slide bar 85 are provided perpendicular to each other. The first synchronous belt 822 and the first slide bar 84 are provided perpendicular to each other, and the second synchronous belt 832 and the second slide bar 85 are provided perpendicular to each other. The first driving block 841 is provided at the first end of the first slide bar 84 and is slidably connected to the first guide support shaft 823, and the second driving block 851 is provided at the first 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 already sufficiently supports the first driving block 841 and the first slide bar 84, the second end of the first slide bar 84 where the first driving block 841 is not provided may be suspended in the air, or may be slidably connected to the housing 51 to further strengthen the support. Those skilled in the art can select according to needs and are not limited here in terms of the specific structure. Since the second guide support shaft 833 already sufficiently supports the second driving block 851 and the second slide bar 85, the second end of the second slide bar 85 where the second driving block 851 is not provided may be suspended in the air, or may be slidably connected to the housing 51 to further strengthen the support, and the specific structure is not limited here.

[0022] In one embodiment, when the first slide bar 84 and the second slide bar 85 move towards or away from the hot-melt cutting material 9 simultaneously, the first slide bar 84 and the second slide bar 85 are respectively driven by the first pulley and the second pulley, and since the rotational speeds of the first pulley and the second pulley are the same, considering the problem that the stroke lengths of the first slide bar 84 and the second slide bar 85 do not match, in order to ensure that the first slide bar 84 and the second slide bar 85 can simultaneously contact the hot-melt cutting material 9, the number of teeth of the first pulley and the second pulley can be determined according to the strokes of the first slide bar 84 and the second slide bar 85. For ease of understanding, specific numerical values are introduced and analyzed in this embodiment, but the specific numerical values should not be considered as restrictive. If the stroke of the second slide bar 85 is twice the stroke of the first slide bar 84, and the stroke of the first slide bar 84 is a, then the stroke of the second slide bar 85 is 2a. Since the first pulley and the second pulley are respectively fixedly connected to the motor shaft, the rotational speeds of the first pulley and the second pulley are equal. The gear teeth of the first pulley mesh with the first synchronous belt 822, and the gear teeth of the second pulley mesh with the second synchronous belt 832. Therefore, the number of teeth of the gear teeth of the second pulley is twice the number of teeth of the gear teeth of the first pulley. In this way, on the premise that the number of teeth of the first synchronous belt 822 and the second synchronous belt 832 is the same, when the motor shaft rotates by a preset angle, it is possible to achieve that the running distance of the second synchronous belt 832 is twice the running distance of the first synchronous belt 822. Thereby, it is guaranteed that when the first slide bar 84 and the second slide bar 85 have different strokes, they can simultaneously contact the hot-melt cutting material 9.

[0023] In one embodiment, the feces collection box further includes a collection box 52 provided below the housing 51 and removably connected to the housing 51. The inner wall of the collection box 52, the bottom wall of the housing 51, and the bottom wall outside 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 a negative pressure to the negative pressure space. After the heat-melting cutting material 9 performs heat-melting cutting on the collection bag 6, the collection bag 6 is heat-melted and closed at the position of the heat-melting cutting material 9. After cutting, a part of the collection bag 6 that is heat-melted and closed falls off along with the cutting, and the other part of the collection bag 6 that is heat-melted and closed becomes the bottom of the new collection bag 6. After the negative pressure device 53 applies a negative pressure, due to the action of the atmospheric pressure, the new collection bag 6 expands toward the inner 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 a fan, and the blowing direction of the fan faces outside the collection box 52.

[0024] In one embodiment, a sealing position sensor 73 and a standby position sensor 74 are provided on the housing 51. 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 heat-melting cutting material 9, and at least a part 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 part of the first slide bar 84 overlaps with the standby position sensor 74.

[0025] In one embodiment, the sealing position sensor 73 and the standby position sensor 74 in this embodiment may each be a hall sensor, a proximity switch, or an infrared sensor. In this embodiment, the sealing position sensor 73 and the standby position sensor 74 are hall position sensors. In other embodiments, the open position sensor 71 and the closed position sensor 72 may be set to different types of sensors. For example, the open position sensor 71 may be set to a hall sensor, and the closed position sensor 72 may be set to a proximity switch. Specific permutation forms are not comprehensively enumerated here. In this embodiment, in order to further improve 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 sealed 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. The sealing position hall sensor and the standby position hall sensor are each communicably connected to the processor, and the processor is fixedly connected to the housing 51.

[0026] In one embodiment, the collection box 52 may be further provided with a detection sensor and a presentation device. The detection sensor is communicably connected to the processor. After the cut collection bag 6 falls into the collection box 52, the detection sensor detects that the collection bag 6 has fallen. If the cut collection bag 6 has not been taken out from the collection box 52, the new collection bag 6 may not be able to be deployed or the deployment effect may not be desirable. After obtaining whether there is a collection bag 6 not taken out in the collection box 52 by the detection sensor and confirming that there is no collection bag 6 not taken out in the collection box 52, the negative pressure device 53 may be turned on to deploy the new collection bag 6. The detection sensor may be any type of sensor having a detection function, such as an infrared sensor, a proximity switch, an acceleration sensor, a weight sensor, etc. The detection sensor may be provided at any position in the collection box 52 according to its own function and detection principle, and at the same time, a plurality of detection sensors may be provided according to actual needs to enhance the detection accuracy. For example, when a weight sensor is adopted, a plurality of weight sensors may be evenly distributed at the bottom of the collection box 52. When one or more of the weight sensors sense that the width of the weight change has reached a preset value, it indicates that the collection bag 6 has already fallen into the collection box 52. At this time, the presentation device communicably connected to the processor by it is controlled to prompt the user to take out the collection bag 6 in a timely manner. At this time, the user may remove the collection box 52, take out the packaged collection bag 6 in the collection box 52, and then reconnect the collection box 52 to the housing 51. In order to facilitate the operation, a fastener may be adopted between the collection box 52 and the housing 51 to achieve a detachable connection. The presentation device may be one or all of a warning light and a horn, and the processor can be used to control the presentation device to give a prompt, which will not be repeatedly described here. After the detection sensor detects that the collection bag 6 has been taken out, the processor controls the fan to exhaust air, and under the action of atmospheric pressure, the new collection bag 6 is sucked in and deployed.

[0027] In this embodiment, the processor may be a centralized or distributed controller. For example, the processor may be a single one-chip microcomputer, or may be composed of a plurality of distributed one-chip microcomputers. By running a control program on the one-chip microcomputer, a plurality of components can be controlled to realize functions.

[0028] In one embodiment, as shown in FIGS. 4 to 11, the feces collection box further includes a sealing assembly and a detection unit. The sealing assembly includes a left sealing portion 11 and a right sealing portion 21. At least one of the left sealing portion 11 and the right sealing portion 21 is slidable relative to the housing 51. The left sealing portion 11 is configured to be closable with the right sealing portion 21. The collection bag 6 is connected to the housing 51, and the outer wall of the collection bag 6 can be abutted by the sealing assembly. The detection unit is rotatably provided on at least one of the left sealing portion 11 and the right sealing portion 21, and the detection unit is rotatable 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 against the right sealing portion 21, the collection bag 6 is sealed by the sealing assembly to prevent the spread of odors. In the process of sealing the collection bag 6 by the sealing assembly, it is possible to judge whether it is full from the state of the detection unit. If it does not fill up, the detection unit can normally rotate toward the bottom wall of the collection bag 6 until the collection bag 6 is sealed. When it fills up, the detection unit cannot rotate toward the bottom wall of the collection bag 6 or the rotation is inhibited, and the user can replace the collection bag 6 based on this. Thereby, the collection bag 6 can be saved and the cleaning frequency of the user can be reduced. At the same time, the spread of odors can also be prevented. After it is detected that the collection bag 6 is full, the packaging assembly performs heat melting sealing and cutting on the full collection bag 6, unfolds a new collection bag 6, and reduces user operation.

[0029] In one embodiment, the left sealing portion 11 and the right sealing portion 21 can be relatively close to or relatively far from each other. The detection unit is rotatably provided on at least one of the left sealing portion 11 and the right sealing portion 21. In this embodiment, the detection unit is rotatably provided on each of the left sealing portion 11 and the right sealing portion 21. The detection unit includes a left rotating shaft 112, a left detection member 12, a right rotating shaft 212, and a right detection member 22. The left detection member 12 is rotatably connected to the left sealing portion 11 via the left rotating shaft 112, and the right detection member 22 is rotatably connected to the right sealing portion 21 via the right rotating shaft 212. In the process of the left sealing portion 11 and the right sealing portion 21 being relatively close to each other, the left detection member 12 and the right detection member 22 slide relative to the housing 51 respectively and the lengths extending from the housing 51 increase. In the process of the left sealing portion 11 and the right sealing portion 21 being relatively far from each other, the left detection member 12 and the right detection member 22 slide relative to the housing 51 respectively and the lengths extending from the housing 51 decrease. Position restricting members are respectively provided on the left sealing portion 11 and the right sealing portion 21 to prevent the situation of exceeding the closed position in the process of the left sealing portion 11 and the right sealing portion 21 being relatively close to each other. In other embodiments, in order to limit the positions of the components, position restricting members may be provided according to the actual process, and the specific structure is not specifically limited here.

[0030] In one embodiment, when the left sealing portion 11 and the right sealing portion 21 are relatively close to each other, the left detection member 12 and the right detection member 22 can rotate toward the bottom wall of the collection bag 6 respectively. When the left sealing portion 11 and the right sealing portion 21 are relatively close to each other, since the lengths of the left detection member 12 and the right detection member 22 extending from the housing 51 increase, the left detection member 12 and the right detection member 22 can realize rotating toward the bottom wall of the collection bag 6 due to their own gravity or the addition of torsion springs on the rotating shafts. When the left sealing portion 11 and the right sealing portion 21 are relatively far from each other, the lengths of the left detection member 12 and the right detection member 22 extending from the housing 51 decrease, and the left detection member 12 and the right detection member 22 rotate in directions opposite to the bottom wall of the collection bag 6 respectively due to the reaction force of the housing 51.

[0031] In one embodiment, when the feces collection box is not full, the left detection member 12 and the right detection member 22 can rotate normally towards the bottom wall of the collection bag 6, the left sealing portion 11 and the right sealing portion 21 can close normally, and the closing position is located at the intermediate position between the two. In an actual use scenario, when the feces collection box is full, since the stacking heights of the pet feces at different positions in the collection bag 6 are uneven, the rotation of one of the left detection member 12 and the right detection member 22 towards the bottom wall of the collection bag 6 is blocked, and the other may be able to rotate normally. At this time, one of the left sealing portion 11 and the right sealing portion 21 can no longer move or the movement speed becomes slow, while the other can move normally. By setting the position regulating members on the left sealing portion 11 and the right sealing portion 21, when the above situation occurs, it can be guaranteed that after the left sealing portion 11 or the right sealing portion 21 reaches the closing position first, it stops without exceeding the closing position. This makes it easier to determine that it is full, and at the same time, it can avoid poor sealing and prevent the spread of strange odors.

[0032] In one embodiment, when collecting using collection bags 6 of different specifications, there are certain differences in the height of the excrement that can be accommodated inside the collection bag 6. In order to effectively detect whether it is full, the left detection member 12 and the right detection member 22 may be set to different length sizes. When the height of the excrement that can be accommodated in the collection bag 6 is high, in order to maximize the utilization of the space inside the collection bag 6, the lengths of the left detection member 12 and the right detection member 22 may be reduced. Conversely, when the height of the excrement that can be accommodated in the collection bag 6 is low, in order to avoid the situation where the collection bag 6 cannot be sealed smoothly for packaging, the lengths of the left detection member 12 and the right detection member 22 may be increased.

[0033] In one embodiment, the left sealing portion 11 and the right sealing portion 21 are driven by a drive transmission assembly. The drive transmission assembly is fixedly provided 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 may be a servo motor or a stepping motor, and in other embodiments, it may be a servo motor. A drive gear shaft 311 is provided on the drive unit 31. The drive gear shaft 311 meshes with the intermediate gear 32, and the intermediate gear 32 is fitted onto the output shaft 33. In one embodiment, the connection form between the intermediate gear 32 and the output shaft 33 is a key connection, and the output shaft 33 is rotatably connected to the housing 51. A transmission unit is transmission-connected to at least one end of the output shaft 33.

[0034] In one embodiment, as shown in FIG. 4, the transmission unit includes a third pulley 34 and a third synchronous belt 41. The third pulley 34 is fitted onto the output shaft 33. In one embodiment, the connection form between the third pulley 34 and the output shaft 33 is a key connection. The third synchronous belt 41 meshes 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. The left drive block 111 and the right drive block 211 are fixedly connected to the third synchronous belt 41 respectively. In order to enable the left sealing portion 11 and the right sealing portion 21 to approach or separate relatively, the left drive block 111 in this embodiment is fixedly connected above the third synchronous belt 41, and at the same time, the right drive block 211 is fixedly connected below the third synchronous belt 41. When the third synchronous belt 41 rotates along the clockwise direction, the left drive block 111 and the right drive block 211 approach or separate relatively, so that the left sealing portion 11 and the right sealing portion 21 are carried along to approach or separate relatively. When the third synchronous belt 41 rotates along the counterclockwise direction, the left drive block 111 and the right drive block 211 separate or approach relatively, so that the left sealing portion 11 and the right sealing portion 21 are carried along to separate or approach relatively.

[0035] In other embodiments of the present application, the left drive block 111 may be fixedly connected below the third synchronous belt 41, and at the same time, the right drive block 211 may be fixedly connected above the third synchronous belt 41. Similarly, it is possible to realize that the left drive block 111 and the right drive block 211 approach or separate relatively. Since the specific realization principle has been described in relatively detail in the foregoing text, it will not be repeatedly described here.

[0036] In one embodiment, in order to achieve a better connection effect, in this embodiment, the left drive block 111 and the right drive block 211 are respectively provided with an engaging portion and a position restricting portion, and the engaging portion and the position restricting portion are fixedly connected. The engaging portion is provided with engaging teeth, and the engaging teeth of the engaging portion are engaged with the belt teeth of the third synchronous belt 41, and the engaging portion is carried along by the belt teeth of the third synchronous belt 41 so as to move. The position restricting portion is provided outside the third synchronous belt 41 and is configured to prevent jumping in the transmission process of the third synchronous belt 41. By setting the position restricting portion, the problem that the third synchronous belt 41 jumps in the transmission process, causing the belt teeth and the engaging portion to disengage and leading to poor transmission, is avoided.

[0037] In one embodiment, in order to avoid relative displacement in the process of the left drive block 111 and the right drive block 211 approaching or separating relatively, the transmission unit further includes a third guide support shaft 42 fixedly provided on the housing 51. The third guide support shaft 42 is provided parallel to the moving direction of the left drive block 111 or the right drive block 211. The left drive block 111 and the right drive block 211 are respectively fitted onto the third guide support shaft 42 and are slidably connected to the third guide support shaft 42.

[0038] In one embodiment, as shown in FIGS. 4 to 5, in order to ensure that the loads on the left sealing portion 11 and the right sealing portion 21 are uniform, two transmission units are provided in this embodiment, and the two transmission units are respectively transmission-connected to both ends of the output shaft 33. Correspondingly, the number of the left drive block 111 and the right drive block 211 is two respectively. The two left drive blocks 111 are respectively located at both ends of the left sealing portion 11, and the two right drive blocks 211 are respectively located at both ends of the right sealing portion 21. In this embodiment, the connection relationship between the output shaft 33 and the transmission unit, the configuration of the transmission unit, and the connection relationship between the transmission unit and the left drive block 111 and the right drive block 211 have been described in detail, and it has been specifically analyzed that the left drive block 111 and the right drive block 211 can relatively approach or relatively separate from each other. Therefore, the above content will not be repeatedly described here. Through the setting of the output shaft 33, the third pulley 34, and the third synchronous belt 41, the consistency of the movements at both ends of the output shaft 33 can be ensured, and further, the certainty of the movements in the process of the relative approach or separation of the left sealing portion 11 and the right sealing portion 21 can be ensured.

[0039] In one embodiment, as shown in FIG. 6, in order to enhance the sealing effect on the collection bag 6 of the sealing assembly, a sealing strip 113 is fixedly provided on the left sealing portion 11 or the right sealing portion 21. In this embodiment, the sealing strip 113 is provided on the side of the left sealing portion 11 facing the right sealing portion 21. In other embodiments, the sealing strip 113 may be provided 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 come into contact, the sealing strip 113 is brought into contact with the outer wall of the collection bag 6. When the left sealing portion 11 and the right sealing portion 21 come into contact, creep occurs in the sealing strip 113, thereby ensuring the sealing effect of the sealing assembly on the collection bag 6. The enhancement of the sealing effect of the sealing assembly on the collection bag 6 may also be realized by other forms. For example, a protrusion is provided on one of the left sealing portion 11 and the right sealing portion 21 on the side facing the other. Correspondingly, a concave groove for fitting with the protrusion is provided on the other of the left sealing portion 11 and the right sealing portion 21. When the left sealing portion 11 and the right sealing portion 21 come into contact, the protrusion is fitted into the concave groove, and the enhancement of the sealing effect on the collection bag 6 is realized by utilizing the principle of a labyrinth seal.

[0040] In one embodiment, as shown in FIGS. 4 to 5, in order for the user to conveniently know whether the feces collection box is full, the housing 51 is further 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 part 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 is in contact with the right sealing portion 21, and at least a part of the sealing assembly overlaps with the closed position sensor 72. When the feces collection box is full, since the volume of the pet excrement in the collection bag 6 is large, in the process of sealing the collection bag 6 by the sealing assembly, the left detection member 12 and the right detection member 22 are affected by the pet excrement and can no longer rotate toward the bottom wall of the collection bag 6. As a result, the sealing assembly cannot seal the collection bag 6, that is, at least a part of the sealing assembly cannot overlap with the closed position sensor 72. In one embodiment, due to the particularity of the use scenario, under certain specific conditions, even if the collection bag 6 is already full and the rotation of at least one of the left detection member 12 and the right detection member 22 toward the bottom wall of the collection bag 6 is blocked, at this time the drive unit 31 is still driving the sealing assembly, and under the action of the driving force, at least one of the left detection member 12 and the right detection member 22 can press the feces and continue to rotate toward the bottom wall of the collection bag 6. That is, it is understood that the sealing assembly can be in the closed state under the action of the driving force, but the time required for the sealing assembly to be in the closed state in such a use case is also longer. Therefore, it is possible to determine whether it is full by presetting the closing time. When the sealing assembly does not become closed within the first preset time, it can be proved that it is full at this time, thereby facilitating subsequent operations.

[0041] The open position sensor 71 and the closed position sensor 72 in this embodiment may be Hall sensors, proximity switches, or infrared sensors. In this embodiment, the open position sensor 71 and the closed position sensor 72 are Hall position sensors. In other embodiments, the open position sensor 71 and the closed position sensor 72 may be set to different types of sensors. For example, the open position sensor 71 may be set to a Hall sensor, and the closed position sensor 72 may be set to a proximity switch. Specific permutation forms are not comprehensively listed here. In this embodiment, in order to further improve the sensitivity of the open position Hall sensor and the closed position Hall sensor, a first magnet 114 is provided in 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 located above the open position Hall sensor. When the sealing assembly is in the closed state, the first magnet 114 is located above the closed position Hall sensor. The open position Hall sensor and the closed position Hall sensor are communicably connected to a processor, and the processor is fixedly connected to the housing 51.

[0042] In one embodiment, during the sealing process of the collection bag 6 by the sealing assembly, the drive unit 31 drives in the forward direction, the drive gear shaft 311 meshes with the intermediate gear 32, the intermediate gear 32 drives the output shaft 33 to rotate, the output shaft 33 drives the third pulleys 34 provided at both ends of the output shaft 33 to rotate, and the third pulleys 34 drive the third synchronous belt 41 to transmit. The left drive block 111 and the right drive block 211 are respectively engaged below and above the third synchronous belt 41 to drive the left sealing portion 11 and the right sealing portion 21 to approach each other relatively. At this time, when the collection bag 6 is not full, the left detection member 12 and the right detection member 22 can rotate toward the bottom wall direction of the collection bag 6, and the left sealing portion 11 can close with the right sealing portion 21. At this time, when the collection bag 6 is full, the rotation of the left detection member 12 and the right detection member 22 toward the bottom wall direction of the collection bag 6 is blocked, and the left sealing portion 11 cannot close with the right sealing portion 21. At this time, the collection bag 6 is already full. The processor controls to operate the packaging motor 81 and drives the first slide bar 84 and the second slide bar 85 to move toward the hot melt cutting material 9. When the first slide bar 84 and the second slide bar 85 are respectively in contact with the hot melt cutting material 9, the second magnet 842 on the first slide bar 84 is located above the sealing position hall sensor. The hot melt cutting material 9 performs a hot melt seal on the collection bag 6. During this process, the packaging motor 81 continuously outputs power outward, thereby ensuring that the first slide bar 84, the second slide bar 85, and the hot melt cutting material 9 are always in contact with the collection bag 6 during the hot melt sealing process, and ensuring the effect of the hot melt seal. After reaching the second preset time, the hot melt cutting material 9 stops heating, and at the same time, the packaging motor 81 drives the first slide bar 84 and the second slide bar 85 to move away from the hot melt cutting material 9. When the second magnet 842 on the first slide bar 84 is located above the standby position hall sensor, the packaging motor 81 stops, and the processor controls the prompting device communicatively connected thereto to prompt the user to timely take out the collection bag 6. The prompting device may be one or all of a warning light and a horn.Regarding the control for the presentation device to perform a presentation using a processor, it will not be repeatedly described here. After the detection sensor detects that the collection bag 6 has been taken out, the processor controls the fan to exhaust air, and due to the action of atmospheric pressure, a new collection bag 6 is sucked in and deployed.

[0043] In this embodiment, the processor may be a centralized or distributed controller. For example, the processor may be a single one-chip microcomputer, or may be composed of a plurality of distributed one-chip microcomputers. By running a control program in the one-chip microcomputer, a plurality of members may be controlled to realize functions.

[0044] As shown in FIG. 14, in this embodiment, a method for using a feces collection box to which the feces collection box according to the embodiment of the present application is applied is provided.

[0046] In one embodiment, after the feces collection box is full, the processor controls the drive unit 31 to drive in the reverse direction, so that the sealing assembly returns to the open state, and then a packaging sealing operation is performed. As shown in FIG. 13, the method of the packaging sealing operation is The processor controls the packaging motor 81 to rotate forward, and the packaging motor 81 drives the first slide bar 84 and the second slide bar 85 to move toward the hot melt cutting material 9 (S31), The first slide bar 84 and the second slide bar 85 reach a predetermined position, 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, the processor starts timing, and the processor controls the hot melt cutting material 9 to thermally melt seal and cut the collection bag 6. In this process, the packaging motor 81 continuously outputs power outward (S32), After the collection bag 6 falls into the collection box 52 and the timing of the processor reaches the second preset time, the processor controls the packaging motor 81 to reverse, and the packaging motor 81 drives the first slide bar 84 and the second slide bar 85 to move away from the hot melt cutting material 9. The second magnet 842 reaches above the standby position hall sensor, the standby position hall sensor collects a signal and transmits it to the processor, and the processor controls the packaging motor 81 to stop (S33), The detection sensor detects whether the collection bag 6 in the collection box 52 has been taken out. If the collection bag 6 has not been taken out, the prompting device is activated to prompt the user to take out the collection bag 6 in a timely manner. If the collection bag 6 has been taken out, the negative pressure device 53 is activated to pull out and deploy a new collection bag 6 (S34).
