DETAILED DESCRIPTION OF THE INVENTION

[0009] Referring to FIGS. 1 to 19, an excrement collector for use in a care device is disclosed. The excrement collector includes a pants assembly 10 that can be worn on a human body, a work head 11 that is removably docked with the pants assembly 10, and a locking mechanism that locks between the work head 11 and the pants assembly 10. The work head 11 includes an excrement container 40 for containing human excrement. The pants assembly 10 includes an excrement outlet 100 through which a human excretes. After the pants assembly 10 is worn on the human body, the excretory part of the human body can be exposed at the excrement outlet 100, and excretes through the excrement outlet 100. The work head 11 is indirectly worn on the human body by the pants assembly 10. The pants assembly 10 includes a connection bracket 3. The pants assembly 10 is removably docked with the work head 11 by the connection bracket 3. The work head 11 can be docked forwardly with the connection bracket 3 of the pants assembly 10, so as to be connected to the pants assembly 10. The work head 11 is insertable and removable in the front-rear direction with respect to the pants assembly 10. The work head 11 can be inserted and connected forwardly to the pants assembly 10. The work head 11 is inserted and connected forwardly to the pants assembly 10 by the connection bracket 3 that is inserted and connected forwardly to the pants assembly 10. By inserting and connecting the work head 11 to the pants assembly 10, the toilet 40 and the excrement outlet 100 are docked.

[0010] The insertion connection and locking of the working head 11 can be realized in cooperation. As the working head 11 is inserted and connected forwardly to the pants assembly 10, the locking mechanism locks the working head 11 and the connection bracket 3 integrally. For the caregiver, the pants assembly 10 can be worn on the human body in the same way as wearing a disposable diaper on the human body, with low difficulty. It is possible to directly observe and confirm whether the pants assembly 10 is worn at an appropriate position through the excretion port 100. When it is discovered that it is not worn at an appropriate position (for example, the excretion port 100 is displaced), timely adjustment is possible, thereby suppressing inappropriate wearing of the pants assembly 10 and further suppressing inappropriate wearing of the subsequent working head 11, reducing the probability of problems such as leakage of excrement. The human body can wear the pants assembly 10 in advance. When it is necessary to connect the working head 11 to the pants assembly 10 (based on the intention of excretion of the human body), the working head 11 can be directly inserted and connected forwardly to the pants assembly 10, which is very quick and convenient. The quick connection between the working head 11 and the pants assembly 10 is realized, and the working head 11 can be directly inserted and connected to the pants assembly 10 and fixed, and can immediately respond to the excretion requirement, so that the working head 11 can be quickly connected, improving the patient's experience. Based on this design, the working head 11 can be quickly and easily connected. Therefore, in normal times when there is no need to receive defecation, the human body can wear the pants assembly 10 without connecting to the working head 11, and the human body can relax and be more comfortable, improving the patient's usage experience. Wait until it is needed, and it is only necessary to quickly connect the working head 11 to the pants assembly 10. After wearing the excrement collector on the human body, the human body can excrete feces into the toilet 40.

[0011] The connection bracket 3 surrounds the discharge port 100. When the connection bracket 3 and the working head 11 are docked, the connection bracket 3 is attached to the working head 11. The locking mechanism includes a left snap member 12, a left cooperation part 30 that fits with the left snap member 12, a right snap member 13, and a right cooperation part 31 that fits with the right snap member 13. The left snap member 12 and the right snap member 13 belong to a part of the working head 11 and are provided on both the left and right sides of the working head 11. The left cooperation part 30 and the right cooperation part 31 belong to a part of the connection bracket 3 and are provided on both the left and right sides of the connection bracket 3. When the connection bracket 3 and the working head 11 are docked, the left snap member 12 fits into the left cooperation part 30, and the right snap member 13 fits into the right cooperation part 31, so that the working head 11 and the connection bracket 3 are integrally locked. When unlocking, by pressing the left snap member 12, the left snap member 12 floats upward to the left with respect to the left cooperation part 30, thereby releasing the snap fit with the left cooperation part 30. By pressing the right snap member 13, the right snap member 13 floats upward to the right with respect to the right cooperation part 31, thereby releasing the snap fit with the right cooperation part 31. The working head 11 can be inserted and removed with one hand with respect to the pants assembly 10, and the working head 11 can be unlocked with one hand. Specifically, place one hand at the bottom of the working head 11 and press the left snap member 12 and the right snap member 13 against each other with the fingers, so that the left snap member 12 and the right snap member float upward and the lock is released.

[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, and 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, and the rotatable angle is small. The working 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. In a state where the connection bracket 3 and the working head 11 are docked, the left snap member 12 can maintain a state of being fitted to the left cooperation part 30 under the action of the elastic force of the left elastic return member 140, and the right snap member 13 can maintain a state of being fitted to the right cooperation part 31 under the action of the elastic force of the right elastic return member 141. As the working head 11 is inserted and connected forward to the pants assembly 10, the left snap member 12 is fitted to the left cooperation part 30 under the action of the elastic force of the left elastic return member 140, and the right snap member 13 is fitted to the right cooperation part 31 under the action of the elastic force of the right elastic return member 141. The left elastic return member 140 and the right elastic return member 141 can adopt springs. When the working head 11 is inserted and connected forward to the pants assembly 10, the left snap member 12 is blocked by the left cooperation part 30 and lifted upward to the left with respect to the left cooperation part 30, and then, under the action of the elastic force of the left elastic return member 140, is fitted to the left cooperation part 30 toward the right. The right snap member 13 is blocked by the right cooperation part 31 and lifted upward to the right with respect to the right cooperation part 31, and then, under the action of the elastic force of the right elastic return member 141, is fitted to the right cooperation part 31. Thus, with the insertion and connection of the working head 11, the left snap member 12 and the right snap member 13 are automatically fitted to the corresponding left cooperation part 30 and right cooperation part 31 almost synchronously. The left snap member 12 lifted upward to the left can return to the right under the action of the elastic force of the left elastic return member 140, and the right snap member 13 lifted upward to the right can return to the left under the action of the elastic force of the right elastic return member 141.

[0014] The left snap protrusion 120 protrudes to the right, and the left cooperation part 30 protrudes 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 protrusion 120, so that the left snap member 12 floats upward to the left relative to the left cooperation part 30, and the left snap protrusion 120 slides over the left cooperation part 30 and returns to the right along with the left elastic return member 140 and is fitted to the left cooperation part 30. The right snap protrusion 130 protrudes to the left, and the right cooperation part 31 protrudes 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 protrusion 130, so that the right snap member 13 floats upward to the right relative to the right cooperation part 31, and the right snap protrusion 130 slides over the right cooperation part 31 and returns to the left along with the right elastic return member 141 and is fitted to the right cooperation part 31.

[0015] In short, the locking mechanism includes at least one snap member and at least one fitting part that can be snapped correspondingly (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). The snap member belongs to a part of the working head 11, the fitting part belongs to a part of the connection bracket 3, the snap member is deflectable, the snap member is returnable under the action of the elastic force of an elastic return member (for example, a spring), and along with the working head 11 being inserted and connected to the pants assembly 10 forwardly, the snap member is fitted to the fitting part under the action of the elastic force of the corresponding elastic return member. Further, when the working head 11 is inserted and connected to the pants assembly 10 forwardly, the snap member is pushed by the elastic force of the corresponding elastic return member and returns, so as to be fitted to the fitting part.

[0016] The working head 11 includes a first casing 4, a second casing 5, and a lower cover 110. The excrement container 40 is provided in the first casing 4.
