[0009] Referring to Figures 1 to 19, a waste collection device for use in caregiving equipment is disclosed, which includes a pant assembly 10 that can be worn on the human body, a work head 11 that is detachably docked with the pant assembly 10, and a locking mechanism that locks the work head 11 and the pant assembly 10 together, the work head 11 including a waste container 40 for containing human waste, the pant assembly 10 including an excretion opening 100 through which a person excretes, after the pant assembly 10 is worn on the human body, the excretory part of the human body can be exposed to the excretion opening 100 and excretion occurs through the excretion opening 100, the work head 11 is indirectly worn on the human body by the pant assembly 10, and the pant assembly 10 includes a connecting bracket 3 The pants assembly 10 is detachably docked with the work head 11 by the connecting bracket 3, and the work head 11 is connected to the pants assembly 10 by being docked forward to the connecting bracket 3 of the pants assembly 10, and the work head 11 is removable in the front-to-back direction relative to the pants assembly 10, and the work head 11 is inserted and connected forward to the pants assembly 10, and the work head 11 is inserted and connected forward to the pants assembly 10 by the connecting bracket 3 which is inserted and connected forward to the pants assembly 10, and the toilet bowl 40 and the excretion opening 100 are docked by the work head 11 being inserted and connected to the pants assembly 10.

[0010] The insertion and locking of the work head 11 can be achieved in conjunction, and as the work head 11 is inserted and connected to the pants assembly 10 facing forward, the locking mechanism locks the work head 11 and the connection bracket 3 together. For caregivers, the pants assembly 10 can be attached to the body in the same way as a disposable diaper, with low difficulty, and it is possible to directly observe and confirm whether the pants assembly 10 is properly positioned through the excretion opening 100. If it is found that it is not properly positioned (for example, the excretion opening 100 is misaligned), it can be adjusted in a timely manner, thereby suppressing improper attachment of the pants assembly 10, and further suppressing improper attachment of the work head 11 thereafter, thereby reducing the probability of problems such as leakage of excrement occurring. The body can wear the pants assembly 10 in advance, and when it is necessary to connect the work head 11 to the pants assembly 10 (based on the body's intention to excrete), the work head 11 is directly inserted into the pants assembly 10 facing forward. The connection is very quick and convenient, enabling the work head 11 and the pants assembly 10 to connect quickly. The work head 11 can be directly inserted and connected to the pants assembly 10 and secured, allowing for immediate response to the need for defecation. The work head 11 can be connected quickly, improving the patient's experience. Based on this design, the work head 11 can be connected quickly and easily. Therefore, when there is no need to defecate, the person can wear the pants assembly 10 without connecting it to the work head 11, allowing the person to relax more comfortably and improving the patient's experience. When needed, the person only needs to wait and quickly connect the work head 11 to the pants assembly 10. After attaching the excrement collector to the person, the person can excrete feces into the stool container 40.

[0011] The connecting bracket 3 surrounds the excretion opening 100, and when the connecting bracket 3 and the work head 11 are docked together, the connecting bracket 3 is attached to the work head 11. The locking mechanism includes a left snap member 12, a left cooperating part 30 that engages with the left snap member 12, a right snap member 13, and a right cooperating part 31 that engages with the right snap member 13. The left snap member 12 and the right snap member 13 belong to a part of the work head 11 and are provided on both the left and right sides of the work head 11. The left cooperating part 30 and the right cooperating part 31 belong to a part of the connecting bracket 3 and are provided on both the left and right sides of the connecting bracket 3. When the connecting bracket 3 and the work head 11 are docked together, the left snap member 12 engages with the left cooperating part 30, and the right snap member 13 engages with the right cooperating part 31, thereby locking the work head 11 and the connecting bracket 3 together. When unlocking, pressing the left snap member 12 causes the left snap member 12 to lift to the left relative to the left cooperative part 30, thereby releasing the snap engagement with the left cooperative part 30. Pressing the right snap member 13 causes the right snap member 13 to lift to the right relative to the right cooperative part 31, thereby releasing the snap engagement with the right cooperative part 31. The work head 11 can be inserted into and removed from the pants assembly 10 with one hand, and the work head 11 can be unlocked with one hand. Specifically, by placing one hand on the bottom of the work head 11 and pressing the left snap member 12 and the right snap member 13 facing each other with the fingers, the left snap member 12 and the right snap member lift up, releasing the lock.

[0012] The connection bracket 3 includes a left recessed area 32 and a right recessed area 33. The left cooperation part 30 is located in the left recessed area 32, and the right cooperation part 31 is located in the right recessed area 33. When the connection bracket 3 and the working head 11 are docked, a part of the left snap member 12 fitted to the left cooperation part 30 is accommodated in the left recessed area 32, and a part of the right snap member 13 fitted to the right cooperation part 31 is accommodated in the right recessed area 33. Further, when the connection bracket 3 and the working head 11 are docked, the front end of the left snap member 12 is fitted into the left recessed area 32, and the front end of the right snap member 13 is fitted into the right recessed area 33. The left snap member 12 includes at least one left snap protrusion 120 that fits with the left cooperation part 30. The left cooperation part 30 includes a slot 300 and / or a rib 301. The right snap member 13 includes at least one right snap protrusion 130 that fits with the right cooperation part 31. The right cooperation part 31 includes a slot 310 and / or a rib 311. The left snap protrusion 120 and the right snap protrusion 130 form a guide inclined surface. By this guide inclined surface, the left snap protrusion 120 and the right snap protrusion 130 slide smoothly along the rib 301 and the rib 311 and fit with the rib 301 and the rib 311. When the connection bracket 3 and the working head 11 are docked, the left snap protrusion 120 is fitted into the corresponding slot 300 and thus fits with the rib 301 on the corresponding slot 300 side. The right cooperation part 31 is fitted into the corresponding slot 300 and thus fits with the rib 301 on the corresponding slot 300 side.

[0013] The left snap member 12 and the right snap member 13 are rotatable, with a small range of rotation. The work head 11 further includes a left elastic return member 140 corresponding to the left snap member 12 and a right elastic return member 141 corresponding to the right snap member 13. When the connecting bracket 3 and the work head 11 are docked, the left snap member 12 can maintain a fitted state in the left cooperating part 30 due to the elastic force of the left elastic return member 140, and the right snap member 13 can maintain a fitted state in the right cooperating part 31 due to the elastic force of the right elastic return member 141. As the work head 11 is inserted and connected forward into the pants assembly 10, the left snap member 12 is fitted into the left cooperating part 30 due to the elastic force of the left elastic return member 140, and the right snap member 13 is fitted into the right cooperating part 31 due to the elastic force of the right elastic return member 141. The left elastic return member 140 and the right elastic return member 141 can be springs. When the work head 11 is inserted and connected to the pants assembly 10 in a forward direction, the left snap member 12 is blocked by the left cooperating part 30 and floats up to the left relative to the left cooperating part 30, and then, due to the action of the elastic force of the left elastic return member 140, it is fitted to the left cooperating part 30 in a rightward direction. Similarly, the right snap member 13 is blocked by the right cooperating part 31 and floats up to the right relative to the right cooperating part 31, and then, due to the action of the elastic force of the right elastic return member 141, it is fitted to the right cooperating part 31. Thus, as the work head 11 is inserted and connected, the left snap member 12 and the right snap member 13 are automatically fitted to the corresponding left cooperating part 30 and right cooperating part 31 in approximately synchronous manner. The left snap member 12, which has been raised to the left, can be returned to the right by the action of the elastic force of the left elastic return member 140, and the right snap member 13, which has been raised to the right, can be returned to the left by the action of the elastic force of the right elastic return member 141.

[0014] The left snap projection 120 projects to the right, and the left cooperation part 30 projects to the left. When the working head 11 is inserted and connected to the pants assembly 10 forwardly, the left cooperation part 30 blocks the left snap projection 120, whereby the left snap member 12 floats upward to the left relative to the left cooperation part 30, and the left snap projection 120 slides over the left cooperation part 30 and returns to the right along with the left elastic return member 140 and fits into the left cooperation part 30. The right snap projection 130 projects to the left, and the right cooperation part 31 projects to the right. When the working head 11 is inserted and connected to the pants assembly 10 forwardly, the right cooperation part 31 blocks the right snap projection 130, whereby the right snap member 13 floats upward to the right relative to the right cooperation part 31, and the right snap projection 130 slides over the right cooperation part 31 and returns to the left along with the right elastic return member 141 and fits into the right cooperation part 31.

[0015] In short, the locking mechanism includes at least one snap member and at least one fitting part (in this embodiment, the fitting part is divided into the left cooperation part 30 and the right cooperation part 31, and the snap member is divided into the left snap member 12 and the right snap member 13) that can be snapped correspondingly.
