Description

[0001] This application is a divisional application of the patent application with the application number 201910489524.4 and the title of "A Docking Device", which was filed on June 6, 2019. Technical Field

[0002] The present invention relates to a waste collection device and a waste collection and treatment system for collecting and treating waste materials generated during medical procedures. Background Art

[0003] During specific surgical procedures, wastes of types such as liquid, semi-solid, and solid will inevitably be generated, specifically including body fluids such as blood, and perfusion solutions introduced into the surgical site during the surgical procedure. In addition, the solid and semi-solid wastes generated during the surgical procedure include tissue fragments and small pieces of surgical materials that may remain in the body part. Ideally, once the waste is generated, it will be collected so that it will neither contaminate the surgical site nor become a biological hazard in the operating room or other locations where the surgical procedure is performed.

[0004] In the prior art, there are various waste collection and treatment systems available for medical staff to collect the waste generated during the surgical procedure during or after the surgery. Its principle is mainly to generate a suction force through a vacuum source to suck the waste generated at the surgical site into a specific collection container. That is, after the system is started, the suction force generated by the vacuum source reaches the surgical site, and thus the waste is sucked and flows into a specific collection container through the pipeline in contact with the surgical site.

[0005] In the prior art, in a medical waste collection and treatment system, the waste materials are collected in a waste collection container connected to a vacuum source. The waste collection container is generally installed on a portable trolley with wheels for easy movement and transportation. Generally speaking, during the suction process, when the storage volume of the waste collection container reaches a predetermined volume, it is necessary to empty the waste collection container. The practice in the early prior art was to push the waste collection device to the docking station and empty and clean it. After the waste collection unit is docked to the docking station, it starts to be emptied. Once emptied, the waste collection container is cleaned by the cleaning system through disinfection and washing. During a series of medical procedures, each procedure requires emptying, and the frequent operation of pushing the waste collection device to the docking station each time brings a lot of inconvenience to the user and affects the medical progress. Therefore, in view of this technical defect, a transfer device dedicated to transporting the waste of the waste collection device to the docking station has been developed, that is, a docking device dedicated to transporting the waste in the waste collection device. This device usually includes two connectors that are docked with two connectors of the waste collection device to form a liquid path connection. One liquid path is used to transfer the waste of the waste collection device to this docking device, and the other liquid path is used to clean the waste collection container of the waste collection device.

[0006] In an example of the prior art system, the docking device usually includes two connectors. The main way of automatically docking with the two connectors of the waste collection device is to roughly match the positions of the docking device and the waste collection device first. When the two are roughly connected, the actuating components at the docking device end can move the two connectors at the docking device end in at most six directions: up, down, front, back, left, and right, so that the two connectors of the docking device are aligned with the two connectors of the waste collection device. Since the connectors in the prior art can only move in at most the up, down, front, back, left, and right directions, the correction directions are only the up, down, left, and right four directions. After alignment in the up, down, left, and right directions, the connectors of the docking device can be inserted by moving back and forth. In the prior art, the structure for realizing the six-direction movement of the connectors at the docking device end requires a bracket that can move in four directions. This bracket requires multiple elastic components and multiple structural components to achieve, plus a stepper motor to realize the movement in the other two directions. The structure is complex, the equipment cost is high, and the connectors can only be inserted after the docking device and the waste collection device are very precisely aligned, that is, the connectors of the docking device and the waste collection device need to be aligned before contact to perform the plug-and-socket matching operation, and cannot continue to align after the plug contacts the socket. This structure not only has a complex alignment operation, but also increases the complexity and cost of the equipment. At the same time, due to the low error tolerance, when the two connectors of the docking device are docked with the two connectors of the waste collection device without alignment, the connectors will be damaged. Summary of the Invention

[0062] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] As Figures 1 - 4 shown, Figure 1 and Figure 2 illustrate a waste collection and treatment system 10, which includes a waste collection device 100 and a docking device 200. Figure 1 Figure 14 shows the waste collection and treatment system 10 when the waste collection device 100 and the docking device 200 are in an undocked state. Figure 2 Figure 15 shows the waste collection and treatment system 10 when the waste collection device 100 and the docking device 200 are in a docked state. The waste collection device 100 can be connected to an external suction pipeline (not shown in the figure) through a consumable cartridge 300. The external suction pipeline can be connected to a suction joint (not shown in the figure), and the suction joint can be a separate joint or attached to a surgical device. The suction force at the suction joint transports the waste through the external suction pipeline to be stored in the waste collection device 100. After the docking device 200 is docked with the waste collection device 100, it can empty the waste in the waste collection device 100 through the docking device 200, and at the same time, it can form a cleaning path for cleaning the waste collection container 109 of the waste collection device 100. The discharge circuit control and flushing circuit control of the waste collection and treatment system 10 are known to those skilled in the art and will not be elaborated here.

[0064] The waste collection device 100 is used in the waste collection and treatment system 10 to collect waste generated during medical procedures and to dock with the docking device 200 to discharge the waste. Refer to Figure 1 and Figure 2 The waste collection device 100 includes: a portable trolley 108, at least one waste collection container 109 installed on the portable trolley, a mating bracket 110, two collection end joints 112, 114, and two floating sleeves 111, 113.

[0065] Portable trolley 108. The portable trolley 108 is moved by the first rollers 105 mounted thereon, and the number of rollers is 4. Specifically, the portable trolley 108 further includes a collection end housing 101. A pusher 102 is provided in the middle part of the housing 101. A collection end display screen 103 is provided on the top of the collection end housing 101. Preferably, the collection end display screen 103 is foldably provided on the collection end housing 101. The portable trolley 108 is also provided with a support hanging rod 104.

[0066] See Figure 3 , Figure 3 is a schematic diagram of the front internal structure of the waste collection device of the present invention. The waste collection container 109 is installed on the portable trolley 108 and is used to store the waste generated during the medical process. In this embodiment, one waste collection container 109 is provided. The waste collection container 109 has a first accommodation chamber 117 and a second accommodation chamber 117, wherein the volume of the first accommodation chamber 116 is larger than the volume of the second accommodation chamber 117. The number of waste collection containers can also be two, that is, it is equivalent to separating the first accommodation chamber 117 and the second accommodation chamber 117 to form two independent waste collection containers. The waste collection container 109 is installed inside the collection end housing 101. Preferably, corresponding observation windows are provided on the collection end housing 101 for observing the waste in the waste collection container 109, such as the liquid level or color, etc. In this example, a first observation window 106 and a second observation window 107 are correspondingly provided for observing the first accommodation chamber 116 and the second accommodation chamber 117 respectively.

[0067] The mating bracket 110 is installed on the chassis 118 of the portable trolley 108 and is used to mate with the docking device 200. The mating bracket 110 forms a mating space 1100 for accommodating the mating head 210 of the docking device 200.

[0068] Two collection end connectors 112, 114 are attached to the mating bracket 110 and are respectively connected to at least one waste collection container 109. One of the collection end connectors 112 is used to discharge the waste in the waste collection container 109, and the other collection end connector 114 is used to introduce the cleaning liquid for cleaning at least one waste collection container 109. In this embodiment, for the convenience of distinction, the collection end connector 112 used to discharge the waste in the waste collection container 109 is called the first collection end connector 112, and the collection end connector 114 used to introduce the cleaning liquid for cleaning the waste collection container 109 is called the second collection end connector 114. See Figure 4 , Figure 4 is a schematic diagram of the side internal structure of the waste collection device of the present invention, as Figure 4As shown, the first collection end joint 112 is connected to the waste collection container 109 through the discharge pipe 122. Specifically, the first collection end joint 112 is connected to the first accommodation bin 116 of the waste collection container 109 through the discharge pipe 122, that is, one end of the discharge pipe 122 is connected to the first collection end joint 112, and the other end is connected to the bottom of the first accommodation bin 116; the second collection end joint 114 is connected to the second accommodation bin 117 of the waste collection container 109 through the cleaning pipe 124, that is, one end of the cleaning pipe 124 is connected to the second collection end joint 114, and the other end is connected to the top of the second accommodation bin 117.

[0069] Two floating sleeves 111, 113 are installed on the mating bracket 110 and sleeved on the two collection end joints 112, 114 correspondingly, for guiding the two docking end joints 211, 213 of the docking device 200 to be correspondingly connected to the two collection end joints 112, 114; the two floating sleeves 111, 113 can move suspended relative to the mating bracket 110 and guide the two docking end joints 211, 213 to engage with the two collection end joints 112, 114. When the docking end joints 211, 213 of the docking device 200 are not connected, the corresponding floating sleeves 111, 113 are in the initial position; during the process of connecting the docking end joints 211, 213, the floating sleeves 111, 113 can move suspended relative to the mating bracket 110 and guide the two docking end joints 211, 213 to engage with the two collection end joints 112, 114.

[0070] In this embodiment, the waste collection device 100 can be described as including:

[0071] A portable trolley 108;

[0072] At least one waste collection container 109 installed on the portable trolley;

[0073] A mating bracket 110;

[0074] A first collection end joint 112 and a second collection end joint 114, the first collection end joint 112 and the second collection end joint 114 are attached to the mating bracket 110; both the first collection end joint 112 and the second collection end joint 114 are connected to at least one waste collection container 109, wherein the first collection end joint 112 is used for discharging the waste in at least one waste collection container 109, and the second collection end joint 114 is used for introducing the cleaning liquid for cleaning at least one waste collection container 109.

[0075] The first floating socket 111 and the second floating socket 113, the first floating socket 111 and the second floating socket 113 are attached to the mating bracket 110, the first floating socket 111 is sleeved on the first collection end joint 112, and the second floating socket 113 is sleeved on the second collection end joint 114; the first floating socket 111 is used to guide the connection of the first docking end joint 211 of the docking device 200 to the first collection end joint 112, and the second floating socket 113 is used to guide the connection of the second docking end joint 214 of the docking device 200 to the second collection end joint 114; when the first floating socket 111 and the second floating socket 113 are not correspondingly inserted into the first collection end joint 112 and the second docking end joint 114, the first floating socket 111 and the second floating socket 113 are in the initial position; during the process of inserting the first docking end joint 211 and the second docking end joint 214, the first floating socket 111 and the second floating socket 113 can move suspended relative to the mating bracket 110 and guide the alignment and engagement of the first docking end joint 211 and the second docking end joint 214 with the first collection end joint 112 and the second collection end joint 114 correspondingly.

[0076] See Figures 1 - 12 , the waste collection and treatment system 10 further includes a docking device 200, and the docking device 200 includes: a mating head 210, at least one actuating component 231, 241, and two docking end joints 212, 214.

[0077] The mating head 210 is used to mate with the mating bracket 110 of the waste collection device 100; specifically, the mating head 210 is inserted into the mating space 1100 of the mating bracket 110 to achieve the preliminary alignment of the docking device 200 and the waste collection device 100.

[0078] At least one actuating component 231, 241, which is arranged in the mating head 210 and can move freely in a specific direction.

[0079] Two docking end connectors 212, 214 are connected to at least one actuating component 231, 241. When the mating head 210 is aligned with the mating bracket 110, the actuating components 231, 241 act to bring the docking end connectors 212, 214 into contact with the floating sleeves 111, 113 and form a docking. The docking end connectors 212, 214 cause the floating sleeves 111, 113 to move in suspension to guide the docking end connectors 212, 214 to engage with the collection end connectors 112, 114. In this embodiment, one of the docking end connectors 212 is used to transport the waste in the waste collection container 109, and the other docking end connector 214 is used to transport the cleaning liquid for cleaning the waste collection container 109. For the sake of distinction, the docking end connector 212 for transporting the waste in the waste collection container 109 is referred to as the first docking end connector 212. The first docking end connector 212 can be docked with the first collection end docking head 112 to form a waste discharge path, and the second docking end connector 214 can be docked with the second collection end docking head 114 to form a path for cleaning the waste collection container 109. Specifically, the second docking end connector 214 is connected to the cleaning interface 207 for filling the cleaning liquid.

[0080] In this embodiment, correspondingly, two actuating components 231, 241 are provided. The one attached to the first docking end connector 212 is called the first actuating component 231, and the one attached to the second docking end connector 214 is called the second actuating component 241. The two actuating components 231, 241 can be pneumatic pumps or stepper motors, or other telescopic motion components or mechanical structures. In this embodiment, a pneumatic pump is preferably used, which can reduce the circuit components of the docking device 200, thereby reducing circuit failures and at the same time reducing the potential risks brought by the complex circuit to the device. Another point is that the speed and force of the pneumatic pump during the pushing process are more conducive to the guiding effect of the floating sleeves 111, 113 on the docking end connectors 212, 214. The docking device 200 further includes a suction pump (not shown in the figure), which is used to connect to the first docking end connector 212 and discharge the waste sucked by the first docking end connector 212 through the discharge connector 208.

[0081] See Figure 5 and Figure 6 As shown in Figure 2 and Figure 3, the two guiding side plates 202 correspondingly match the chassis 118 of the portable trolley 108. At the same time, in order to more conveniently and accurately mate the docking device 200 with the waste collection device 100, guide rails 209 are further provided inside the guiding side plates 202. Preferably, each guiding side plate 202 is provided with 2-4 guide rails 209. The guide rails 209 are made of flexible materials and can be used as buffer strips to prevent wear caused by the impact between the docking device 200 and the waste collection device 100.

[0082] The mating head 210 includes a front panel 215, and a suction device 216 is installed on the front panel 215. The suction device 216 is an electromagnet. When the mating head 210 of the docking device 200 substantially enters the mating space 1100 of the mating bracket 110, the suction device 216 is turned on. The suction device 216 provides a preset suction force to quickly and automatically join the mating head 210 of the docking device 200 with the mating bracket 110 of the waste collection device 100 to form a tight connection structure.

[0083] See Figure 6 、 Figure 10 、 Figure 11 , the mating head 210 further includes a mating plate 217. The mating plate 217 includes two guiding notches 211, 213 for engaging the floating sleeves 111, 113, and the docking end joints 212, 214 can correspondingly pass through the two guiding notches 211, 213. Specifically, among the two guiding notches 211, 213, the guiding notch 211 for passing through the first docking end joint 212 is called the first guiding notch 211, and the guiding notch 213 for passing through the second docking end joint 214 is called the second guiding notch 213. Preferably, the shape of the guiding notch is approximately U-shaped, its inner end is an arc surface, and the side ends 235, 245 are wedge-shaped structures, so that the opening width from the front end to the inner end of the notch gradually decreases. Such a structure enables the floating sleeves 111, 113 to gradually align with the guiding notches 211, 213 without causing collision during the process of pushing the mating head 210 into the mating space 1100 of the mating bracket 110. The docking device 200 further includes a number of second rollers 205.

[0084] In addition, as Figure 5 shown, the docking device 200 further includes a baffle 220. When not connected to the waste collection device 100, the baffle 220 is in the first position, as Figure 15 shown, covering the two docking end joints 212, 214; when connected to the waste collection device 100, the baffle 220 is in the second position, exposing the two docking end joints 212, 214 to contact the floating sleeves 111, 113 of the waste collection device 100 to form a docking.

[0085] The baffle 220 includes a horizontal plate 221 for shielding the two docking end joints 212, 214 and a vertical plate 222 that contacts the waste collection device 100 and can be pushed by the waste collection device 100. When the mating head 210 is pushed into the mating space 1100, the waste collection device 100 pushes the vertical plate 222 of the baffle 220, causing the horizontal plate 221 to enter the interior of the docking device 200, exposing the two docking end joints 212, 214. After the mating head 210 is separated from the mating space 1100, the baffle 220 can be manually reset to the first position to shield the mating plate 217 and the docking end joints 212, 214.

[0086] Preferably, the docking device 200 further includes a baffle reset assembly connected to the baffle 220 for resetting the baffle 220 from the second position to the first position. As Figures 16 - 17 shown, the baffle reset assembly includes at least one baffle displacement assembly 2210 connected to the baffle 220 and at least one elastic assembly 2214 that cooperates with the baffle displacement assembly 2210. The baffle displacement assembly 2210 is located inside the housing 201. In this embodiment, the number of the baffle displacement assembly 2210 and the elastic assembly 2214 is two. Specifically, the baffle displacement assembly 2210 includes a fixed rod 2212 and a baffle connecting member 2213 that can slide on the fixed rod 2212. The elastic assembly 2214 is connected to the baffle connecting member 2213. The baffle connecting member 2213 is sleeved on the fixed rod 2212 and can slide on the fixed rod 2212, and the baffle connecting member 221 is connected to the horizontal plate 221. Specifically, it can be an irreversible or detachable connection such as welding or clamping. When the mating head 210 is pushed into the mating space 1100, the waste collection device 100 pushes the vertical plate 222 of the baffle 220, causing the horizontal plate 221 to enter the interior of the docking device 200, exposing the two docking end joints 212, 214. At the same time, the baffle connecting member 2213 slides on the fixed rod 2212 and compresses the elastic assembly 2214. After the mating head 210 is separated from the mating space 1100, the elastic assembly 2214 resets the baffle 220 to the first position, and the elastic assembly 2214 is a spring sleeved on the fixed rod 2212.

[0087] See Figure 18 , Figure 18Another installation method for the elastic component is that the elastic component 2214 is sleeved on the fixed rod 2212 and is located between the baffle connecting piece 2213 and the vertical plate 222. One end of the elastic component 2214 is fixed to the baffle connecting piece 2213, and the other end is fixed to the vertical plate 222. When the baffle 220 is pushed into the mating space 1100 by the mating head 210, the waste collection device 100 pushes the vertical plate 222 of the baffle 220, so that the horizontal plate 221 enters the interior of the docking device 200, exposing the two docking end joints 212 and 214. At the same time, the baffle connecting piece 2213 slides on the fixed rod 2212 and compresses and stretches the elastic component 2214. After the mating head 210 is separated from the mating space 1100, the elastic component 2214 resets the baffle 220 to the first position. The elastic component 2214 is a spring sleeved on the fixed rod 2212.

[0088] Wherein the baffle connecting piece 2213 is further used to lock the baffle 220 at the first position when the baffle 220 is reset to the first position, preventing the baffle 220 from falling off. Alternatively, a separate device can also be provided to lock the baffle 220 at the first position.

[0089] Furthermore, the baffle 220 further includes at least one sliding component 2211, such as Figure 10 As shown, the mating head 210 further includes a sliding track 2181 that matches the sliding component 221. The sliding component 221 is a metal or plastic sheet that can slide on the sliding track 2181 and is connected to the horizontal plate 221.

[0090] Furthermore, the baffle 220 further includes guide rail sliding holes 2221 that are the same in number as the guide rails 209 and are used for the guide rails 209 to pass through.

[0091] The mating head 210 further includes a head base 204. The front end panel 215 and the mating plate 217 are both mounted on the head base 204. At the same time, the actuating components 231 and 241 are also mounted on the head base 204. Among them, the width of the mating plate 217 is wider than that of the front end panel 215. The two calibration sides 218 of the mating plate 217 protrude from the two side plates of the head base 204, and the width of the mating plate 217 is also wider than that of the head base 204. The calibration side 204 is a wedge-shaped structure, that is, the calibration side 204 is an inclined surface, so that the width of the front part of the mating plate 217 is smaller than that of the rear part. During the process of pushing the mating head 210 into the mating space 1100 of the mating bracket 110, the mating head 210 and the mating bracket 110 can automatically perform position calibration, and at the same time, the risk of damage caused by collision is greatly reduced. When the mating head 210 of the docking device 200 is roughly aligned with the mating space 1100 of the mating bracket 110, after the suction device 216 is turned on, the instantaneous suction force increases. The calibration side 218 and the guiding bayonets 211 and 213 will prevent the mating head 210 and the mating bracket 110 from suffering serious collision even when they are not completely aligned. Thus, it can provide a tolerance for operation during the alignment process and will not cause damage to the device. Preferably, the rear part of the mating plate 217 can form a tight or interference fit with the mating space 1100. A clearance fit is formed between the front part of the mating plate 217 and the mating space 1100.

[0092] See Figures 7 - 9 , Figure 7 is a schematic structural diagram of the mating bracket 110, Figure 8 is a schematic structural diagram of the floating sleeve in the second floating state, Figure 9 is Figure 8 a cross-sectional view taken along the line E-E.

[0093] As Figure 7 shown, the mating bracket 110 includes a fixing plate 115 and a guiding plate 118. The guiding plate 118 and the fixing plate 115 form a mating space 1100 for accommodating the mating head 210 of the docking device 200. Specifically, the fixing plate 115 is located at the top of the mating bracket 110. The fixing plate 118 is composed of the back plate and two side plates of the mating bracket 110. In this embodiment, the fixing plate 115 and the guiding plate 118 are of a split structure, and the two can be installed and fixed by means of screws or welding. In other embodiments, the fixing plate 115 and the guiding plate 118 can also be integrally formed.

[0094] As Figure 8 and Figure 9As shown, the fixing plate 115 is provided with two fixing through holes 163 for installing two floating sleeves 111 and 113. The first floating sleeve 111 and the second floating sleeve 113 respectively pass through the two fixing through holes 153 and 163. Specifically, the fixing plate 115 includes two limiting and fixing sleeves 134 and 144 respectively installed in the two fixing through holes 163. The structures of the two floating sleeves 111 and 113 are the same. Taking the second floating sleeve 113 as an example, the floating sleeve 113 refers to the second floating sleeve 113, which will not be elaborated. The floating sleeve 113 includes: a floating sleeve 130 and a first elastic member 155. The floating sleeve 130 is sleeved on the collecting end joint 114, passes through the limiting and fixing sleeve 134, and the floating sleeve 130 includes a guiding port 154 for guiding the docking end joint 212 and a suspendable port 135 for engaging with the limiting and fixing sleeve 134 in the initial state. When the docking end joint 214 of the docking device 200 is not connected, the suspendable port 135 engages with the limiting and fixing sleeve 134, and the floating sleeve 113 is in the initial position; during the process of connecting the docking end joint 214, the suspendable port 135 moves relative to the limiting and fixing sleeve 134, and guides the docking end joint 214 to align with the corresponding collecting end joint 114 and complete the engagement to form a cleaning passage. The first elastic member 155 is located between the guiding port 154 and the limiting and fixing sleeve 134, and is used to limit the moving range of the floating sleeve 130 during the process of connecting the docking end joint 214 and return the floating sleeve 113 to the initial state after the docking end joint 214 is removed.

[0095] As Figure 8 and Figure 9 shown, taking the limiting and fixing sleeve 134 as an example, the limiting and fixing sleeve 134 includes: a clamping portion 1344, a docking top 1340 for docking with the suspendable port 135 in the initial state, a first limiting inner cavity 1342 for limiting one end of the first elastic member 155, and a second limiting inner cavity 1343 for accommodating and limiting the position of the guiding port 154. In other embodiments, the first limiting inner cavity 1342 and the second limiting inner cavity 1343 can be combined into one inner cavity. The clamping portion 1344 is used to clamp the lower end of the limiting and fixing sleeve 134 into the sleeve clamping groove 1531 of the fixing through hole 153, and the upper end is fastened by a first card 133 for fastening the limiting and fixing sleeve 134 arranged between the limiting and fixing sleeve 134 and the fixing plate 115. The first card 133 includes a first tightening structure 139. Similarly, the limiting and fixing sleeve 144 also has the same structure, and the upper end is fastened by a first card 143 for fastening the limiting and fixing sleeve 144 arranged between the limiting and fixing sleeve 144 and the fixing plate 115. The first card 143 includes a tightening structure 149.

[0096] The floating ferrule 113 and the collecting end joint 114 are fixedly connected to form an integral body. The outer walls of the floating ferrule 113 and the collecting end joint 114 can be integrally formed, or they can be connected by threads as shown in Figure 9 . After the docking end joint 214 is connected, when subjected to the thrust of the actuating assembly, the first elastic member 155 is compressed. At this time, the docking top 1340 of the floating port 135 and the limiting fixed sleeve 134 are separated. At this time, the floating sleeve 113 and the collecting end joint 114 connected thereto can achieve floating movement under the thrust of the actuating assembly and the acting force of the first elastic member 155, and can swing within a certain range in any direction, so as to realize the guiding and position correction of the docking end joint 214 and complete the final alignment and engagement. An outer tube 132 is also provided at the guiding port 135 of the floating sleeve 130, and the outer tube 132 is provided with a limiting edge 131 that cooperates with the mating head 210. The diameter of the limiting edge 131 is greater than the diameter of the main tube body of the outer tube 132. As shown in Figure 12 , Figure 12 is a schematic diagram after the mating head 210 and the mating bracket 110 are mated. For the convenience of description, it is set to the state where the first collecting end docking head 112 and the first docking end joint 212 are engaged while the second collecting end docking head 114 and the second docking end joint 214 are not engaged. As shown in Figure 12 stated, the limiting edge 131 is mainly for cooperating with the mating plate 217. After the mating plate 217 is pushed in, the limiting edge 131 is located below the mating plate 217, and the main tube body of the outer tube 132 is caught in the guiding bayonet 213 of the mating plate 217. When the floating sleeve 113 and the collecting end joint 114 connected thereto can achieve floating movement under the thrust of the actuating assembly 241 and the acting force of the first elastic member 155, when it rises to the position of the mating plate 217, the limiting edge 131 can limit the position of the floating sleeve 113, thereby preventing the floating sleeve 113 from swinging excessively and increasing the difficulty of docking the collecting end joint 114 and the docking end joint 214. Refer to Figure 11 , the guiding bayonet 211 includes a first upper card slot 233 and a second upper card slot 234. Refer to Figure 11 and Figure 12 , the outer tube 132 of the floating ferrule 111 contacts the first upper card slot 233, that is, the first upper card slot 233 is used to guide the floating ferrule 111, and the second upper card slot 234 can limit the position of the floating ferrule 111, especially the position of the limiting edge 131 of the floating ferrule 111. Specifically, the opening of the second upper card slot 234 is larger than the opening of the first upper card slot 233. The other guiding bayonet 213 also has the same structure, including a first upper card slot 243 and a second upper card slot 244.

[0097] The outer tube 132 of the floating sleeve 113 and the floating sleeve 130 form a limiting groove 1301 for defining the other end of the first elastic member 155. The first elastic member 155 is specifically a first spring. Refer to Figure 9 As shown, the first elastic member 155 is sleeved on the floating sleeve 130. One end is positioned by the limiting groove 1301, and the other end is positioned by the first limiting inner cavity 1342. The outer tube 142 of the floating sleeve 114, i.e., the second floating sleeve 114, and the floating sleeve 140 form a limiting groove 1401 for defining the other end of the first elastic member 155. The first elastic member 155 is specifically a first spring. Refer to Figure 9 As shown, the first elastic member 155 is sleeved on the floating sleeve 140. One end is positioned by the limiting groove 1401, and the other end is positioned by the first limiting inner cavity 1442.

[0098] To better achieve the docking of the mating head 210 and the mating bracket 110, the docking top 1340 includes a frustum-shaped first guiding notch 1341 for guiding the suspendable port 135. The suspendable port 135 is a snap ring detachably fixed to the floating sleeve 130. Correspondingly, the snap ring 135 includes a frustum-shaped guiding portion 1351 for matching with the first guiding notch 1341. The guiding portion 1351 and the first guiding notch 1341 are similar in shape and size, and their respective cross-sections are inclined planes. When the suspendable port 135 contacts the docking top 1340, the plane with a smaller diameter contacts the plane with a larger diameter of the first guiding notch 1341. The gap between the guiding portion 1351 and the first guiding notch 1341 is the space for correction and adjustment, and the first guiding notch 1341 can guide the above-mentioned guiding portion 1351 to gradually align. A second card 136 for fastening the snap ring 135 is also provided between the floating sleeve 130 and the snap ring 135. The first card 133 includes a second tightening structure 138. The guiding port 154 is provided with a frustum-shaped guiding opening to better guide the second docking end joint 214 into the second floating socket 113.

[0099] As Figures 12 - 14 shown, when the first docking end joint 212 is inserted into the first floating socket 111, the first actuating assembly 231 pushes the first docking end joint 212 upward through the connecting rod 232, and after correction, the combination of the first docking end joint 212 and the first collecting end joint 112 is formed Figure 13The waste discharge passage indicated by the arrow. After the second actuating component 241 is closed, the connecting rod 242 retracts. After the second docking end joint 214 is separated from the second collection end joint 114, the second docking end joint 214 exits the second floating socket 113, and the cleaning passage is interrupted between the second docking end joint 214 and the second collection end joint 114. Taking the second collection end joint 114 as an example, the second collection end joint 114 includes a joint seal 183 that can automatically seal the joint port 181. The joint seal 183 contains a joint plunger 184, and a second elastic member 185 is sleeved on the joint plunger 184, with one end located inside the joint seal 183 and the other end sleeved on the joint fixing portion 186. The second collection end joint 114 is opened and closed through the joint seal 183 and is automatically sealed through the second elastic member 185.

[0100] Implementing the embodiments of the present invention has the following beneficial effects:

[0101] First, in the waste collection device of the embodiments of the present invention, after the docking end joint of the docking device is matched with the floating socket, the collection end joint is then docked with the docking end joint. After the docking end joint is inserted into the floating socket, the floating socket can move suspendedly to guide the docking end joint into the floating socket and gradually align with the collection end joint. Moreover, the suspended movement of the floating socket also ensures that even when the docking end joint and the floating socket are not fully aligned, the docking end joint will not impact the floating socket, nor will it collide misaligned with the collection end joint, causing wear. That is, during the docking process between the waste collection device and the docking device, there can be a large position tolerance, which can not only improve the docking accuracy rate, but also facilitate the operation of the user. At the same time, it can also reduce the damage caused to the collection end joint and the docking end joint due to inaccurate alignment.

[0102] Second, the structure for realizing position guidance and correction in the waste collection device of this embodiment is simple and has low complexity, requires less raw materials, is easy to manufacture, and reduces costs.

[0103] Furthermore, the docking device in this embodiment is provided with multiple structures that can automatically correct and align the position during the docking process with the waste collection device, which can provide a greater position tolerance, improve the docking accuracy rate, and also facilitate the operation of the user.

[0104] Finally, the docking device in this embodiment is provided with a mating plate with a correction side, which can provide a greater position tolerance during the docking process between the docking device and the waste collection device, improve the docking accuracy rate, and also facilitate the operation of the user. At the same time, it reduces the impact risk between the docking device and the waste collection device. Meanwhile, the docking device is provided with a baffle that can automatically reset, which can effectively protect the docking end joint, prevent the docking end joint from being bruised and damaged in the non-working state, extend the service life of the device, and reduce the maintenance cost.

[0105] The above-disclosed is only a preferred embodiment of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
