【Technical Field】 【0001】 This application claims the priority of a Chinese patent application with an application date of March 31, 2023 and an application number of 202310334542.1, and all the contents of the said application are incorporated herein by reference. 【0002】 This application relates to the technical field of pet toilets, for example, to a feces collection box and a full detection method. 【Background Art】 【0003】 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 a pet uses 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. By closing the garbage bag, packaging it, and temporarily storing it, a pet toilet that can timely process feces and reduce the spread of odor is provided. However, the device according to related technologies needs to close the garbage bag, package it, and replace it with a new garbage bag every time the pet finishes using the toilet. One garbage bag can only collect feces once, which leads to resource waste and at the same time increases the frequency of user cleaning. 【Summary of the Invention】 【0004】 This application provides a feces collection box and a full detection method that can solve the problems of waste of garbage bags and increased cleaning frequency of pet toilets in related technologies. 【0005】 The present invention provides a collection box for collecting pet feces, comprising a housing, a sealing assembly, a collection bag, and a detection unit, wherein the sealing assembly comprises a left sealing portion and a right sealing portion, at least one of the left sealing portion and the right sealing portion being slidable relative to the housing, the left sealing portion being configured to be able to close with the right sealing portion, the collection bag being connected to the housing, the outer wall of the collection bag being able to be abutted by the sealing assembly, the detection unit being rotatably mounted on at least one of the left sealing portion and the right sealing portion, and the detection unit being configured to be able to abut the pet feces such that when the collection bag is full the detection unit's rotation toward the bottom wall of the collection bag is prevented. 【0006】 The present invention provides a method for detecting fullness of a waste collection box, which applies the above-described embodiment of the waste collection box, and includes: driving a sealing assembly to close; after a predetermined time, the detection element detects whether the sealing assembly is in the closed position; based on the detection result that the sealing assembly is in the closed position, it determines that the waste collection box is not full and stops driving the sealing assembly to move; and based on the detection result that the sealing assembly is not in the closed position, it determines that the waste collection box is already full and drives the sealing assembly in the reverse direction to return it to the open position.

The examples of the embodiments are shown in the drawings, and the same or similar reference numerals represent only the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are for interpretation purposes only, and should not be understood as limiting the present application. 【0012】 In related technologies, pet toilets are directly connected to the outside, and pet feces cannot be removed in a timely manner, resulting in the spread of odor. In related technologies, after a pet has finished using the toilet, a vibrating or stirring device separates the bedding or cat litter mixed with pet feces, discharges it into a garbage bag, seals the garbage bag, packages it for temporary storage, and provides a pet toilet that can process feces in a timely manner, thereby reducing the spread of odor. However, with the devices in related technologies, each time a pet finishes using the toilet, the garbage bag must be sealed and packaged and replaced with a new one, meaning that feces can only be collected once per garbage bag, leading to resource waste and increasing the frequency of user cleaning. 【0013】 In contrast, this embodiment provides a waste collection box that can similarly prevent the spread of odor and simultaneously solve the above-mentioned problem. 【0014】 As shown in Figures 1 to 9, the present invention provides a waste collection box comprising a housing 5, a sealing assembly, a collection bag 6, and a detection unit, wherein the sealing assembly comprises 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 being slidable relative to the housing 5, the left sealing portion 11 being configured to abut and close with the right sealing portion 21, the collection bag 6 being connected to the housing 5, the outer wall of the collection bag 6 being able to abut against the sealing assembly, the detection unit being rotatably mounted on at least one of the left sealing portion 11 and the right sealing portion 21, the detection unit being rotatable toward the bottom wall of the collection bag 6, and when the collection bag 6 is full, the detection unit being able to abut against the pet feces, thereby providing a waste collection box. After the left sealing section 11 and the right sealing section 21 come into contact, the collection bag 6 is sealed by the sealing assembly, preventing the spread of odors. During the sealing process of the collection bag 6 by the sealing assembly, the detection unit can determine whether or not it is full. If it is not full, the detection unit can rotate normally toward the bottom wall of the collection bag 6 until it is sealed. If it is full, the detection unit will be unable to rotate toward the bottom wall of the collection bag 6 or its rotation will be obstructed, allowing the user to replace the collection bag 6. This saves the collection bag 6, reduces the frequency of cleaning for the user, and prevents the spread of odors. 【0015】 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 both 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 by the left rotating shaft 112, and the right detection member 22 is rotatably connected to the right sealing portion 21 by 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 5 and the length extending from the housing 5 increases. 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 5 and the length extending from the housing 5 decreases. Position restricting members are provided on the left sealing portion 11 and the right sealing portion 21 respectively to prevent the situation that the left sealing portion 11 and the right sealing portion 12 exceed the closed position in the process of being relatively close to each other. For those skilled in the art, in order to limit the position of the parts, the position restricting members may be provided according to the actual situation of the process, and the specific structure is not specifically limited here. 【0016】 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 towards the bottom wall of the collection bag 6. When the left sealing portion 11 and the right sealing portion 21 are relatively close to each other, the length of the left detection member 12 and the right detection member 22 extending from the housing 5 increases. Therefore, the left detection member 12 and the right detection member 22 can realize rotation towards the bottom wall of the collection bag 6 due to their own gravity or the addition of a torsion spring on the rotating shaft. When the left sealing portion 11 and the right sealing portion 21 are relatively far from each other, the length of the left detection member 12 and the right detection member 22 extending from the housing 5 decreases, and the left detection member 12 and the right detection member 22 rotate in the direction opposite to the bottom wall of the collection bag 6 respectively due to the reaction force of the housing 5. 【0017】 In one embodiment, if the collection box is not full, the left detection member 12 and the right detection member 22 can each rotate normally toward the bottom wall of the collection bag 6, the left sealing part 11 and the right sealing part 21 can close normally, and the closed position is located at an intermediate position between the left sealing part 11 and the right sealing part 21. In actual use, when the collection box is full, the accumulation height of pet feces at different positions in the collection bag 6 is uneven, so the rotation of one of the left detection member 12 and the right detection member 22 toward the bottom wall of the collection bag 6 may be hindered, while the other may be able to rotate normally. In this case, one of the left sealing part 11 and the right sealing part 21 may not be able to move any further or its movement speed may be slowed, while the other may be able to move normally. By setting the position regulating members provided on the left sealing part 11 and the right sealing part 21, it is possible to ensure that when the above situation occurs, the left sealing part 11 or the right sealing part 21 reaches the closed position first and then stops without exceeding the closed position. This makes it easier to determine whether or not the container will be full, and at the same time, it helps to avoid sealing problems and prevent the spread of unpleasant odors. 【0018】 In one embodiment, when collection is performed using collection bags 6 of different specifications, there is a certain difference in the height of the excrement that can be contained inside the collection bag 6. In order to effectively detect whether or not the bag is full, the left detection member 12 and the right detection member 22 may be set to different lengths. If the height of the excrement that can be contained inside the collection bag 6 is high, the lengths of the left detection member 12 and the right detection member 22 may be reduced in order to maximize the use of the space inside the collection bag 6. Conversely, if the height of the excrement that can be contained inside the collection bag 6 is low, the lengths of the left detection member 12 and the right detection member 22 may be increased in order to avoid the collection bag 6 not being able to be properly sealed and packaged. 【0019】 In one embodiment, as shown in FIGS. 2 to 9, the left sealing portion 11 and the right sealing portion 21 are driven by a driving transmission assembly. The driving transmission assembly is fixedly provided on the housing 5. The driving transmission assembly includes a driving unit 31, an intermediate gear 32 and a transmission unit. The driving unit 31 is fixedly connected to the housing 5. The driving unit 31 may be a servo motor or a stepping motor. In one embodiment, the driving unit 31 is a servo motor. A driving gear shaft 311 is provided on the driving unit 31. The driving gear shaft 311 meshes with the intermediate gear 32. 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 key connection. The output shaft 33 is rotatably connected to the housing 5. A transmission unit is transmission-connected to at least one end of the output shaft 33. 【0020】 In one embodiment, the transmission unit includes a toothed pulley 34 and a synchronous toothed belt 41. The toothed pulley 34 is fitted onto the output shaft 33. In one embodiment, the connection form between the toothed pulley 34 and the output shaft 33 is key connection. The synchronous toothed belt 41 meshes with the toothed pulley 34. A left driving block 111 is provided at the end of the left sealing portion 11, and a right driving block 211 is provided at the end of the right sealing portion 21. The left driving block 111 and the right driving block 211 are respectively fixedly connected to the synchronous toothed belt 41. In order to enable the left sealing portion 11 and the right sealing portion 21 to approach or separate relatively, the left driving block 111 in this embodiment is fixedly connected above the synchronous toothed belt 41, and at the same time the right driving block 211 is fixedly connected below the synchronous toothed belt 41. When the synchronous toothed belt 41 rotates along the clockwise direction, the left driving block 111 and the right driving 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 synchronous toothed belt 41 rotates along the counterclockwise direction, the left driving block 111 and the right driving 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. 【0021】 In other embodiments of the present invention, the left drive block 111 may be fixedly connected below the synchronous toothed belt 41, and the right drive block 211 may be fixedly connected above the synchronous toothed belt 41. This makes it possible to similarly bring the left drive block 111 and the right drive block 211 closer together or further apart. The specific implementation principle has been explained in relatively detail above, so it will not be repeated here. 【0022】 To achieve a better connection effect, in this embodiment, the left drive block 111 is provided with a first occlusal portion 1112 and a first position regulating portion 1111, and the right drive block 211 is provided with a second position regulating portion 2111 and a second occlusal portion 2112, the first occlusal portion 1112 is fixedly connected to the first position regulating portion 1111, and the second occlusal portion 2112 is fixedly connected to the second position regulating portion 2111. The first occlusal portion 1112 and the second occlusal portion 2112 are provided with occlusal teeth, which bite into the belt teeth of the synchronous toothed belt 41, and the belt teeth of the synchronous toothed belt 41 guide the first occlusal portion 1112 and the second occlusal portion 2112 to move. The first position regulating portion 1111 and the second position regulating portion 2111 are located outside the synchronous toothed belt 41 and are configured to prevent jumping during the transmission process of the synchronous toothed belt 41. By providing the first position regulating portion 1111 and the second position regulating portion 2111, the problem of the belt teeth detaching from the first occlusal portion 1112 and the second occlusal portion 2112, respectively, due to jumping during the transmission process of the synchronous toothed belt 41, which leads to transmission failure, is avoided. 【0023】 In one embodiment, in order to avoid relative displacement between the left drive block 111 and the right drive block 211 during the process of moving closer to or further apart from each other, the transmission unit further comprises a guide support shaft 42, which is fixedly mounted to the housing 5. The guide support shaft 42 is positioned parallel to the direction of movement of the left drive block 111 or the right drive block 211, and the left drive block 111 and the right drive block 211 are fitted onto the guide support shaft 42 and slidably connected to the guide support shaft 42, respectively. 【0024】 In one embodiment, as shown in Figure 4, in order to ensure that the load on the left sealing section 11 and the right sealing section 21 is uniform, two transmission units are provided in this embodiment, and the two transmission units are each transmitted to both ends of the output shaft 33. Correspondingly, there are two left drive blocks 111 and two right drive blocks 211. The two left drive blocks 111 are located at both ends of the left sealing section 11, and the two right drive blocks 211 are located at both ends of the right sealing section 21. In this embodiment, the connection relationship between the output shaft 33 and the transmission units, the configuration of the transmission units, and the connection relationship between the transmission units and the left drive blocks 111 and the right drive blocks 211 have already been explained in detail, and it has already been specifically analyzed that it is possible to make the left drive blocks 111 and the right drive blocks 211 relatively close or relatively far apart, so the above content will not be explained again here. The configuration of the output shaft 33, toothed pulley 34, and synchronous toothed belt 41 ensures the synchronization of motion at both ends of the output shaft 33, and further ensures the reliability of motion during the process in which the left sealing portion 11 and the right sealing portion 21 move closer to or further apart relative to each other. 【0025】 In one embodiment, as shown in Figure 5, a sealing strip 113 is fixedly provided on either the left sealing portion 11 or the right sealing portion 21 to enhance the sealing effect of the sealing assembly on the collection bag 6. 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 comes into contact with the outer wall of the collection bag 6. Creep occurs in the sealing strip 113 when the left sealing portion 11 and the right sealing portion 21 come into contact, thereby ensuring the sealing effect of the sealing assembly on the collection bag 6. In other embodiments, the enhancement of the sealing effect of the sealing assembly on the collection bag 6 may be achieved by other means. 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 that engages with a protrusion is provided in 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 engages with the groove, and the sealing effect on the collection bag 6 is enhanced by utilizing the principle of a labyrinth seal. 【0026】 In one embodiment, as shown in Figure 4, the housing 5 is further provided with an open position sensor 71 and a closed position sensor 72 so that the user can conveniently know whether the collection box is full or not, 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 part 11 abuts against the right sealing part 21, and at least a part of the sealing assembly overlaps with the closed position sensor 72. When the collection box is full, the volume of pet waste in the collection bag 6 is large, so during the sealing process of the collection bag 6 by the sealing assembly, the left detection member 12 and the right detection member 22 are affected by the pet waste and can no longer rotate toward the bottom wall of the collection bag 6, and as a result the sealing assembly can no longer seal the collection bag 6, that is, at least a part of the sealing assembly can no longer overlap with the closed position sensor 72. In one embodiment, due to the specific nature of the usage scenario, under certain conditions, the collection bag 6 may already be full, preventing at least one of the left detection member 12 and the right detection member 22 from rotating toward the bottom wall of the collection bag 6. However, the drive unit 31 is still driving the sealing assembly, and the driving force allows the left detection member 12 and / or the right detection member 22 to press against the feces and continue to rotate toward the bottom wall of the collection bag 6. In other words, the sealing assembly can be closed by the driving force, but it is understood that the time required for the sealing assembly to be closed in such usage scenarios is also longer. Therefore, by pre-setting the closing time, it is possible to determine whether or not the bag is full. If the sealing assembly cannot be closed within the pre-set time, it can be proven that the bag is full, thereby facilitating subsequent operations. 【0027】 In this embodiment, the open position sensor 71 and the closed position sensor 72 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 to a proximity switch, and all possible permutations are not listed here exhaustively. In this embodiment, in order to further improve the sensitivity of the open position Hall sensor and the closed position Hall sensor, a magnet 114 is provided in one of the left sealing section 11 and the right sealing section 21. When the sealing assembly is in the open state, the magnet 114 is located above the open position Hall sensor. When the sealing assembly is in the closed state, the magnet 114 is located above the closed position Hall sensor. The open position Hall sensor and the closed position Hall sensor are communicateable to a processor, which is fixedly connected to the housing 5. 【0028】 In one embodiment, during the sealing process of the collection bag 6 by the sealing assembly, the drive unit 31 is driven in the forward direction, the drive gear shaft 311 is meshed with the intermediate gear 32, the intermediate gear 32 is driven to rotate the output shaft 33, the output shaft 33 is driven to rotate toothed pulleys 34 provided at both ends of the output shaft 33, and the toothed pulleys 34 are driven to transmit the synchronous toothed belt 41. The left drive block 111 and the right drive block 211 are meshed below and above the synchronous toothed belt 41, respectively, and are driven to bring the left sealing section 11 and the right sealing section 21 relatively close to each other. If the collection bag 6 is not filled to capacity, the left detection member 12 and the right detection member 22 can rotate toward the bottom wall of the collection bag 6, and the left sealing section 11 can come into contact with the right sealing section 21. If the collection bag 6 is already full, the left detection member 12 and the right detection member 22 are prevented from rotating toward the bottom wall of the collection bag 6, and the left sealing part 11 can no longer contact the right sealing part 21. At this point, an audible and luminous alarm device controlled by the processor and communicating with the processor may prompt the user to replace the collection bag 6 in a timely manner. The audible and luminous alarm device may consist of a warning light and / or a horn. Related technologies may be referenced for controlling the audible and luminous alarm device using a processor, and will not be repeated here. 【0029】 In this embodiment, the processor may be a centralized or distributed controller. For example, the processor may be a single, standalone microcontroller, or it may consist of multiple distributed microcontrollers. By running a control program on the microcontrollers, each component can be controlled to realize its function. 【0030】 This embodiment provides a method for detecting when a waste collection box is full, which is performed by applying the waste collection box according to the embodiment of the present invention. 【0031】 As shown in Figures 10 and 11, the full-capacity detection method is The drive unit 31 is driven in the forward direction to pull the magnet 114 in at least a portion of the sealed assembly away from above the open position Hall sensor, and the processor receives the signal to pull the magnet 114 away and controls the drive unit 31 to move the sealed assembly for a preset time, S1. If, within a preset time, the magnet 114 in at least a portion of the sealed assembly reaches above the closed position Hall sensor, and the processor receives the arrival signal of the magnet 114 within a preset time, it determines that the waste collection box will not be filled to capacity, and the processor controls the drive unit 31 to stop, and the sealed assembly enters the closed state S2. S3 includes determining that the waste collection box is full based on the fact that the sealed assembly does not reach above the closed position Hall sensor on the closed position sensor 72 within a preset time, and the processor has not received an arrival signal within a preset time, and the processor controls the drive unit 31 to drive in the reverse direction to return the sealed assembly to the open state, and at the same time an audible and visual alarm is issued to prompt the user to replace the collection bag 6.
