[0038] The utility model mainly provides a defecation and urination nursing machine, which is mainly used in a defecation and urination nursing system to assist patients with limited mobility to collect and process large and small feces and urine.

[0039] The specific structure of the defecation and urination care machine will be mainly described below.

[0040] Reference Figures 1 to 9 In the embodiment of the utility model, the defecation and urination care machine comprises:

[0041] The host comprises a housing 200, the housing 200 is provided with a mounting hole 210 communicating with the interior thereof, the mounting hole 210 has a hole wall provided with an avoidance groove 212 extending along the hole depth direction thereof, and a limiting groove 213 extending along the circumference of the mounting hole 210, the limiting groove 213 communicating with the avoidance groove 212;

[0042] A toilet collector and a connecting pipe 100, wherein the connecting pipe 100 has a first end and a second end, wherein the first end is connected to the toilet collector, and a limiting protrusion 110 is provided on the outer side wall of the second end, wherein the limiting protrusion 110 is used to pass through the avoidance groove 212 and enter into the limiting groove 213 to cooperate with the limiting groove 213 in a limiting manner.

[0043] Specifically, in this embodiment, the host is mainly used to provide negative pressure power to absorb feces and urine, and transmit water sources for flushing, etc. The specific form of the host can be many, and no special limitation is made. Take a hard shell 200 as an example. One end of the connecting pipe 100 is detachably connected to the shell 200, and the other end is connected to the feces collector. The feces collector is worn on the human body. When the human body has feces and urine, it first enters the feces collector, and then is transported to the waste box in the host under the action of the host. The hole depth direction of the mounting hole 210 is consistent with the wall thickness direction of the shell 200, and the avoidance groove 212 extends along the hole depth direction of the mounting hole 210. The avoidance groove 212 is located on the inner side wall of the mounting hole 210, and the notch faces the middle of the mounting hole 210. One end of the avoidance groove 212 is open and connected to the outside of the shell 200, and the other end is connected to the limit groove 213. In this way, the limiting protrusion 110 can enter the avoidance groove 212 from the outside of the shell 200 (when the second end is inserted into the mounting hole 210), and move along the length direction of the avoidance groove 212. When the limiting protrusion 110 moves to the other end of the avoidance groove 212 (the end away from the opening, the position connected to the limiting groove 213), the second end can be rotated so that the limiting protrusion 110 moves along the circumferential direction of the mounting hole 210, thereby entering the limiting groove 213, so that the limiting groove 213 prevents the limiting protrusion 110 from moving along the hole depth direction of the mounting hole 210, thereby preventing the second end from being separated from the mounting hole 210 (shell 200). There are many ways to connect the first end to the toilet, such as fastening connection by screws, buckles 125, etc. The limiting protrusion 110 protrudes from the peripheral side wall of the second end, and the limiting protrusion 110 can have many shapes, such as columnar, block, etc., which are not specifically limited here, and a rectangular block is taken as an example. The depth of the limiting groove 213 can be greater than the depth of the avoiding groove 212, so that the limiting protrusion 110 is more difficult to escape after entering the limiting groove 213. It is worth noting that the wall thickness of the housing 200 corresponding to the position where the mounting hole 210 is opened can be greater than the wall thickness of other positions, thereby providing sufficient space for opening the avoiding groove 212 and the limiting groove 213.

[0044] In this embodiment, a mounting hole 210 is provided on the housing 200, and an avoidance groove 212 extending in the hole depth direction and a limiting groove 213 extending in the circumferential direction of the mounting hole 210 are provided on the hole wall of the mounting hole 210, and the limiting groove 213 is connected with the avoidance groove 212; at the same time, a limiting protrusion 110 is provided on the outer side wall of the second end portion, and the limiting protrusion 110 is inserted into the avoidance groove 212 when the second end is inserted into the mounting hole 210, and the limiting protrusion 110 moves to the avoidance groove 212 and the limiting protrusion 110. When the connecting pipe 100 is in the position of being connected to the groove 213, the second end can be rotated to make the limiting protrusion 110 enter the limiting groove 213, so that the limiting groove 213 prevents the limiting protrusion 110 from moving axially along the mounting hole 210, so that the second end cannot move axially along the mounting hole 210, and the connection between the second end and the housing 200 is achieved; when it is necessary to disassemble the connecting pipe 100, the second end is first rotated to make the limiting protrusion 110 move into the avoidance groove 212, and then the second end is pulled out from the mounting hole 210;

[0045] It is worth noting that when the defecation and feces care machine is working, the negative pressure formed in the main unit sucks the feces and feces in the feces collection container, so that the connecting pipe 100 has a tendency to move toward the main unit (friction is applied to the inner wall of the connecting pipe 100 during the gas suction process), so that the second end has a tendency to move toward the shell 200, so that the limiting protrusion 110 squeezes the inner wall of the limiting groove 213, so that the squeezing force between the limiting protrusion 110 and the groove wall of the limiting groove 213 is greatly increased, so that the friction between the two is greatly increased, so that the second end is not easy to rotate, so that the second end is not easy to detach from the shell 200, thereby further strengthening the connection between the second end and the shell 200. Stability: When the defecation and urination care machine stops working, the connecting pipe 100 has no tendency to move, so that the second end has no tendency to move toward the shell 200, thereby greatly reducing the friction between the limiting protrusion 110 and the groove wall of the limiting groove 213. At this time, the second end can be easily rotated to make the limiting protrusion 110 move from the limiting groove 213 to the avoidance groove 212, and detach from the shell 200 along the avoidance groove 212, thereby realizing the unlocking of the connecting pipe 100 and the shell 200; in this way, it can not only ensure the convenience of loading and unloading of the connecting pipe 100 and the shell 200, but also make the connection between the second end and the shell 200 very reliable when the defecation and urination care machine is in working state.

[0046] In some embodiments, the connecting pipe 100 includes a pipe body 130 and a pipe sleeve 120, wherein the pipe body 130 includes a connection end connected to the housing 200, and the pipe sleeve 120 is sleeved on the connection end. Specifically, in this embodiment, in order to facilitate the manufacture and assembly of the pipe body 130, the pipe body 130 and the pipe sleeve 120 are separately arranged, so that the pipe sleeve 120 and the pipe body 130 can be processed and produced separately. The pipe sleeve 120 needs to form a limiting protrusion 110 structure that cooperates with the housing 200, and the pipe body 130 needs to be installed with a water pipe, a sewage suction pipe, a warm air pipe, etc. In some embodiments, a signal pipe (for the passage of a signal line) and the like need to be installed. By separately arranging the pipe body 130 and the pipe sleeve 120, not only can the two be processed separately to improve production efficiency, but it can also be beneficial to the maintenance of the connecting pipe 100. When some parts fail or are damaged, there is no need to replace the entire part, and only the damaged parts need to be replaced.

[0047] In some embodiments, in order to improve the tightness of the connection between the connecting pipe 100 and the shell 200, the pipe sleeve 120 includes a snap-fit ​​section 121, a connecting section 123, and a transition section 122 located between the snap-fit ​​section 121 and the connecting section 123; the snap-fit ​​section 121 is detachably connected to the mounting hole 210, and the connecting section 123 is detachably connected to the connecting end; the overall shape of the transition section 122 is a frustum, and its radial dimension gradually decreases from the connecting section 123 to the snap-fit ​​section 121. Specifically, in this embodiment, the overall shape of the transition section 122 is a frustum, and in the process of the pipe sleeve 120 and the mounting hole 210 being matched, the snap-fit ​​section 121 of the pipe sleeve 120 with a smaller radial dimension first enters the mounting hole 210, and the dimension of the transition section 122 entering the mounting hole 210 gradually increases until the outer wall of the transition section 122 abuts against the inner wall of the mounting hole 210. By setting the radial dimension of the transition section 122 to be gradual, the sleeve 120 can well block the mounting hole 210, thereby preventing mosquitoes, dust, etc. in the external environment from entering the housing 200 through the mounting hole 210. At the same time, by setting the transition section 122 to be gradual in size, the sleeve 120 can be suitable for mounting holes 210 of different sizes. In particular, when there is a processing error in the mounting hole 210, the sleeve 120 can overcome the error of the mounting hole 210 and ensure the blocking effect.

[0048] In some embodiments, in order to improve the stability of the matching between the sleeve 120 and the housing 200, the limiting protrusion 110 is provided on the outer side wall of the clamping section 121, and the number of the limiting protrusion 110 is multiple, and the multiple limiting protrusions 110 are arranged at intervals along the circumference of the clamping section 121. The multiple limiting protrusions 110 are arranged at intervals, so that the limiting protrusions 110 are distributed on the peripheral side of the clamping section 121. After the limiting protrusions 110 are matched with the limiting grooves 213, the surroundings of the clamping section 121 can be well limited, which is conducive to improving the stability of the matching between the sleeve 120 and the housing 200.

[0049] In some embodiments, there are many ways to connect the connection end with the connection section 123, such as threaded connection, etc. Take the buckle 125 connection as an example. Specifically, a buckle position is set on the outer wall of the connection end, and a buckle 125 matching the buckle position is set on the side wall of the connection section 123. When the pipe sleeve 120 is sleeved on the connection end, the buckle 125 is buckled with the buckle position. By setting the connection end and the connection section 123 to be connected with the buckle 125, the installation and removal of the pipe sleeve 120 and the connection end are very convenient, and the stability of the connection can also be ensured. When the pipe sleeve 120 or the connection end needs maintenance, it can be conveniently removed.

[0050] In some embodiments, in order to ensure smooth conduction between the pipeline of the connection end and the host, the connection end includes a cylindrical end body and a plurality of joint structures 131 located in the end body, one end of the plurality of joint structures 131 is used to communicate with the host, and the other end is used to connect the water pipe, the air duct, and the sewage suction pipe. The joint structure 131 may include a water pipe joint 135, an air duct joint 133, and a sewage suction pipe joint 132. A corresponding connecting structure is provided on the housing 200 corresponding to the joint structure 131. The joint structure 131 corresponds to the connecting structure one by one, so that the water pipe, the air duct, and the sewage suction pipe can be reliably connected to the host.

[0051] In some embodiments, in order to ensure that the limiting protrusion 110 can smoothly pass through the avoidance groove 212 and enter the limiting groove 213, the main unit also includes a light guide structure 300, the shell 200 has an installation groove 220, and a light board is arranged in the installation groove 220; the light guide structure 300 is installed on the shell 200 corresponding to the installation groove 220; an avoidance notch 310 is arranged on the outer wall of the light guide structure 300 corresponding to the avoidance groove 212, and the avoidance notch 310 is used for the limiting protrusion 110 to pass through.

[0052] Specifically, in the present embodiment, the light board can be in many forms, such as including multiple sections, and multiple sections are arranged at intervals. In the present embodiment, the overall shape of the light board is set in a ring shape as an example. A number of lamp beads are arranged on the light board, and the light emitted by the lamp beads can be emitted outward through the light guide structure 300. The light guide structure 300 is made of a light-transmitting material, and its specific shape can be in many forms, such as corresponding to the shape of the light board, and a ring shape is taken as an example. The mounting groove 220 is arranged around the mounting hole 210, and the light guide structure 300 is installed on the shell 200 corresponding to the mounting hole 210, so that the light is emitted around the mounting hole 210. By opening an avoidance notch 310 on the light guide structure 300, and setting the avoidance notch 310 corresponding to the avoidance groove 212, the limiting protrusion 110 can first pass through the avoidance notch 310, and then enter the avoidance groove 212. In this way, after the light guide structure 300 and the shell 200 are tightly connected together, the connection between the connecting pipe 100 and the shell 200 will not be hindered, so that the limiting protrusion 110 can smoothly pass through the avoidance notch 310 into the avoidance groove 212 and then enter the limiting groove 213.

[0053] The light guide structure 300 can be in many forms. The following is an example of a description. The light guide structure 300 is arranged in an annular shape. The light guide structure 300 includes an inner ring plate and an outer ring plate. The outer ring plate is fixedly connected to one groove wall of the mounting groove 220, and the inner ring plate is in contact with the other groove wall of the mounting groove 220. The inner ring plate includes an open portion and a clamping portion. One side of the open portion is connected to the outer ring plate, and the other side is connected to the clamping portion. The radial dimension of the open portion gradually increases from the clamping portion to the outer ring plate. The clamping portion has a clamping step, and the clamping step is clamped on the groove wall of the mounting groove 220. The avoidance notch 310 is formed with the inner side wall of the open portion. The overall shape of the inner ring plate is trumpet-shaped, and the overall shape of the outer ring plate is cylindrical. The side of the cylindrical shape is connected to the edge of the trumpet-shaped large diameter end. After the clamping portion of the inner ring plate is clamped with the groove wall of the mounting groove 220, it is connected to the groove wall of the mounting groove 220. By making the overall shape of the inner ring plate trumpet-shaped, this shape can be adapted to the overall shape of the transition section 122, so that the contact area between the transition section 122 and the mounting hole 210 is greatly increased, so that the transition section 122 can be replaced to block the mounting hole 210, thereby further preventing mosquitoes and dust in the external environment from affecting the operation of the defecation care machine.

[0054] In some embodiments, in order to improve the connection reliability between the connecting pipe 100 and the housing 200, one end of the limiting groove 213 is connected to the avoiding groove 212, and the other end is blocked. In this embodiment, by blocking one end of the limiting groove 213 away from the avoiding groove 212, when the limiting protrusion 110 moves in the limiting groove 213, the blocked end can limit the movement range of the limiting protrusion 110. Preventing the connecting pipe 100 from rotating too much relative to the housing 200 greatly reduces the phenomenon of the connecting pipe 100 being separated from the housing 200 due to rotation, thereby greatly improving the connection reliability of the connecting pipe 100 after matching with the housing 200.

[0055] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
