Description

Technical Field

[0001] The invention relates to the technical field of excretion assistance equipment, in particular to a toilet chair. Background Art

[0002] For traditional commode chairs, users need to rely on their own strength to stand up after using the toilet. However, for weak users, it is difficult to stand up by their own strength. In response to this, commode chairs that can provide assistance for standing up have been developed.

[0003] For example, in the patent with the announcement number CN218960610U, a "commode chair" is disclosed, which includes a base, a backrest, a seat and a torsion spring. The seat is provided with a toilet groove, and the seat is rotatably connected to the base at the end away from the backrest. The torsion spring is provided with two torsion arms, one torsion arm is connected to the base, and the other torsion arm is connected to the seat. The torsion spring can drive the seat to lift.

[0004] When in use, the user sits down and the torsion spring twists and deforms; when the user wants to stand up, as the user gradually stands up, the torsion spring will gradually return to its original position, driving the seat to rise. The seat can fit closely against the user's buttocks to support the user to stand, thereby assisting the user to stand.

[0005] However, it is inconvenient for the weak and upper limb disabled user to wipe the anus after defecation. In the above toilet chair, the seat is close to the user's buttocks, and the backrest is located at the back of the user. The seat and the backrest block the view, making it inconvenient for the caregiver to help wipe.

[0006] Therefore, how to assist the user to stand and facilitate the caregiver to wipe the user's anus is a technical problem that needs to be solved at present. Summary of the invention

[0007] The present invention aims at the above-mentioned deficiencies in the prior art and provides a toilet chair, which can not only assist the user to stand, but also facilitate the caregiver to wipe the user's anus.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0014] Furthermore, a receiving groove is provided in the middle of the base, the receiving groove is communicated with the toilet bowl, a plastic bag is provided in the receiving groove, the bag opening of the plastic bag is sleeved on the top of the base, and the seat plate is pressed on the bag opening of the plastic bag.

[0015] Furthermore, a hook is provided on the side of the base, and a handle is provided at the bag opening of the plastic bag, and the handle is hung on the hook.

[0016] Furthermore, piston cavities are provided inside the two plate bodies, piston holes are provided at the bottoms of the two plate bodies, the piston holes are connected to the piston cavities, air holes are provided at the upper ends of the two plate bodies on the side close to each other, the air holes are arranged downward, the air holes are connected to the piston cavities, a piston plate is provided in the piston cavity, a piston column is provided in the piston hole, the upper end of the piston column is connected to the piston plate, a stop block is provided at the lower end of the piston column, the stop block abuts against the top of the base, a spring is sleeved on the piston column, one end of the spring abuts against the stop block, and the other end of the spring abuts against the bottom surface of the plate body.

[0017] Furthermore, a hidden groove is provided on the top surface of the base, and the stop block is abutted and matched with the bottom of the hidden groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the commode chair of the present invention, the lifting mechanism can drive the two plates to move upward, and the plates can lift the user's buttocks to assist the user to stand up; and the window between the two guide frames and the two open plates will not block the caregiver's line of sight, making it convenient for the caregiver to wipe the user's anus from behind the user. In short, the commode chair of the present invention can not only assist the user to stand up, but also will not cause line of sight obstruction, making it convenient for the caregiver to wipe the user's anus. Furthermore, during the wiping process, the user can always sit on the plate, saving the user's physical strength and improving the user's comfort.

[0020] 2. In the toilet chair of the present invention, the two opened plates drive the two buttocks of the user to open, so that the anus of the user is exposed, which further facilitates the caregiver to wipe the anus of the user, and the anus can be wiped more cleanly, reducing the risk of bacterial infection caused by unclean wiping.

[0021] 3. The action of lifting the two plates and the action of opening the two plates are performed simultaneously, which is beneficial to improving the adjustment efficiency; and the action of lifting the two plates and the action of opening the two plates are driven by the lifting mechanism at the same time, so there is no need to set up power sources separately to drive the two plates to lift and drive the two plates to open, which is beneficial to saving energy.

[0022] 4. The degree of inclination of the guide rod changes during the up and down movement of the guide rod, so the transverse hole needs to have a sufficient height in the vertical direction to allow the degree of inclination of the guide rod to change. When the plate body falls back onto the base, the guide rod is in a horizontal state. Since the height of the transverse hole is large enough, the guide rod located in the transverse hole will shake in the vertical direction. In the present invention, since the guide hole is inclined, the inclined hole wall of the guide hole can limit the shaking of the guide rod in the vertical direction, which is beneficial to ensure the stability of the guide rod, and then it is beneficial to improve the stability of the plate body, thereby improving the stability and reliability of the toilet chair of the present invention.

[0023] 5. When the lifting mechanism is used to drive the two plates to lift, the two plates drive the support rods and the armrests to lift together, which can help the user to hold the armrests for leverage when getting up, making it more convenient for the user to stand.

[0024] 6. When the two boards assist the user to stand, the boards are in an inclined state, and the gripping rod at the front end of the armrest board is in a vertical state with the board body, so the gripping rod at the front end of the armrest board is more convenient for the user to grasp and leverage, making the toilet chair of the present invention more convenient to use.

[0025] 7. The setting of the fixed back plate and the movable back plate makes it convenient for the user to lean on it when defecating, which improves the user's comfort. In addition, because the fixed back plate and the movable back plate can adapt to the opening and approaching movements of the two plates, the fixed back plate and the movable back plate can be lifted together with the two plates, so the fixed back plate and the movable back plate can avoid blocking the sight of the caregiver, and will not delay the caregiver from wiping the user's anus.

[0026] 8. By putting a plastic bag on the base, the user is allowed to excrete excrement into the plastic bag, which makes it convenient for caregivers to discard the plastic bag containing excrement and clean up the excrement, thereby improving the convenience of use.

[0027] 9. When the two plates fall back onto the base, the two plates repress the plastic bag to prevent the plastic bag from falling off under the impact of excrement, thereby improving the reliability of the plastic bag in receiving the excrement.

[0028] 10. By hanging the handle of the plastic bag on the hook, the risk of the plastic bag falling off can be further reduced, and the reliability of the plastic bag on the base can be further improved.

[0029] 11. By arranging a stop block, a piston column, a piston plate, a spring, a piston chamber, and a piston hole, the air in the piston chamber can be replenished when the two plates are lifted; when the two plates are lowered, the piston plate pushes the air in the piston chamber out of the air hole, and the air flow discharged from the air hole blows toward the plastic bag, so that the plastic bag can be expanded by the air flow, increasing the distance between the inner wall of the plastic bag and the user, reducing the probability of the user's excrement splashing back to the user's private parts, and improving the comfort of use.

[0030] 12. Because the airflow can open the plastic bag, there is no need for the caregiver to manually open the plastic bag, which can reduce the labor intensity of the caregiver.

[0031] 13. The blowing action of the airflow is linked with the lifting action of the board body, and there is no need to use an additional power source to drive the airflow blowing, which is conducive to saving energy.

[0032] 14. By setting up a hidden groove, when the two plates fall back, the stop block abuts against the bottom of the hidden groove, allowing the bottom of the two plates to fall directly to the top of the base, thereby improving the support reliability of the plates and then improving the reliability of the user sitting on the plates.

[0053] DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Embodiment 1:

[0056] See also Figures 15 to 18 A toilet chair comprises a base 1, a seat plate and a lifting mechanism.

[0057] See also Figure 8 and Fig.14 A rotating seat 11 is fixedly mounted on the front end of the base 1.

[0058] See also Fig.17 The rotating seat 11 is rotatably mounted with a horizontal axis 111 through a bearing, and the horizontal axis 111 can rotate relative to the rotating seat 11. A vertical axis 1111 is fixedly mounted on the horizontal axis 111, and the axial direction of the vertical axis 1111 is perpendicular to the axial direction of the horizontal axis 111.

[0059] See also Figure 8 and Fig. 9 Two guide frames 12 are fixedly mounted at the rear end of the base 1 , a window 121 is provided between the two guide frames 12 , and each of the two guide frames 12 is provided with a guide hole 122 , and the distance between the upper ends of the two guide holes 122 is greater than the distance between the lower ends of the two guide holes 122 .

[0060] See also Figure 2 , the seat plate includes two plate bodies 2. Figure 3 A toilet bowl 21 is provided between the two plates 2. Figure 1 and Figure 4 The front ends of the two plates 2 are connected by a vertical shaft 1111. Figure 2 , a guide rod 22 is fixedly mounted at the rear ends of the two plates 2. Fig.15 , a guide rod 22 is disposed in a guide hole 122 .

[0061] The lifting mechanism includes a crossbeam 3 and a linear drive structure.

[0062] See also Fig.10 The rear side walls of the two guide frames 12 are fixedly mounted with slide rails 123, the cross beam 3 is vertically slidably matched with the two slide rails 123, and a transverse hole 31 is provided on the cross beam 3. Fig.16, the two guide rods 22 are both arranged in the transverse hole 31.

[0063] The linear drive structure is fixedly mounted on the side of the guide frame 12, and is used to drive the crossbeam 3 to move in the vertical direction. The linear drive structure can be one of an oil cylinder, an air cylinder, and an electric push rod. The air cylinder includes a rod cylinder and a rodless air cylinder 4. In this embodiment 1, see Figure 8 and Fig.10 , a rodless cylinder 4 is used as a linear drive structure. The rodless cylinder 4 has the advantage of saving installation space. The piston 41 in the rodless cylinder 4 is fixedly installed with the cross beam 3. When the piston 41 in the rodless cylinder 4 moves up and down, the cross beam 3 can be driven to move up and down. When an oil cylinder is used as a linear drive structure, the cylinder body of the oil cylinder is fixedly installed on the side of the guide frame 12, and the piston rod of the oil cylinder is fixedly installed with the cross beam 3. When the piston rod of the oil cylinder is extended and retracted, the cross beam 3 can be driven to move up and down.

[0064] The working principle of this embodiment 1 is as follows:

[0065] (1) When defecating, the user sits on the two plates 2, and the feces falls through the toilet seat 21 between the two plates 2.

[0066] (2) After the user has defecated, the user still sits on the two plate bodies 2, and then starts the linear drive structure to drive the cross beam 3 to move upward. The cross beam 3 supports the two guide rods 22 to move upward, and the two guide rods 22 drive the rear ends of the two plate bodies 2 to move upward. The two plate bodies 2 rotate upward with the horizontal axis 111 as the rotation center. The two plate bodies 2 support the user's buttocks and tilt them up to help the user gradually stand up.

[0067] At the same time, the two guide rods 22 slide from bottom to top along the guide holes 122 during the upward movement. Since the distance between the two guide holes 122 gradually increases from bottom to top, the distance between the two guide rods 22 gradually increases. The two guide rods 22 drive the two plate bodies 2 to rotate and open with the vertical axis 1111 as the rotation center. The two plate bodies 2 drive the two buttocks of the user to open, exposing the user's anus.

[0068] The caregiver reaches out from the rear side of the user through the window 121 between the two guide frames 12 and the toilet seat 21 between the two plate bodies 2 to wipe the user's anus. When wiping the anus, the window 121 between the two guide frames 12 will not block the view, and the two opened plate bodies 2 will not block the view. In addition, the two opened plate bodies 2 drive the two buttocks of the user to open, which can increase the observation field of view and facilitate the caregiver to wipe the user's anus. During the wiping process, the user can always sit on the plate body 2, saving the user's physical strength and improving the user's comfort.

[0069] (3) When resetting the plate body 2, the linear drive structure drives the cross beam 3 to move downward, and the cross beam 3 drives the two guide rods 22 to move downward. The two guide rods 22 drive the two plate bodies 2 to rotate downward with the horizontal axis 111 as the rotation center, so that the two plate bodies 2 fall onto the base 1; at the same time, the two guide rods 22 slide down along the guide holes 122 during the downward movement. Since the distance between the two guide holes 122 gradually decreases from top to bottom, the distance between the two guide rods 22 gradually decreases, and the two guide rods 22 drive the two plate bodies 2 to close with the vertical axis 1111 as the rotation center, thereby realizing the resetting of the plate body 2.

[0070] According to the working principle of Example 1, it can be seen that Example 1 has the following effects:

[0071] First, in the commode chair of the present embodiment 1, the lifting mechanism can drive the two plates 2 to move upward, and the plates 2 can lift the user's buttocks to assist the user to stand up; and the window 121 between the two guide frames 12 and the two opened plates 2 will not block the caregiver's line of sight, making it convenient for the caregiver to wipe the user's anus from behind the user. In short, the commode chair of the present embodiment 1 can not only assist the user to stand up, but also will not cause line of sight obstruction, making it convenient for the caregiver to wipe the user's anus.

[0072] Second, in the toilet chair of the present embodiment 1, the two opened plates 2 drive the two buttocks of the user to open, so that the user's anus is exposed, which further facilitates the caregiver to wipe the user's anus, and the anus can be wiped more cleanly, reducing the risk of bacterial infection caused by unclean wiping.

[0073] Third, the action of lifting the two plate bodies 2 and the action of opening the two plate bodies 2 are performed simultaneously, which is beneficial to improving the adjustment efficiency; and, the action of lifting the two plate bodies 2 and the action of opening the two plate bodies 2 are driven by the lifting mechanism at the same time, and there is no need to set up power sources separately to drive the two plate bodies 2 to lift and drive the two plate bodies 2 to open, which is beneficial to saving energy.

[0074] Fourth, the inclination of the guide rod 22 changes during the upward and downward movement of the guide rod 22. Fig.13 , the transverse hole 31 needs to have a sufficient height H in the vertical direction to allow the inclination of the guide rod 22 to change. When the plate body 2 falls back onto the base 1, the guide rod 22 is in a horizontal state. Since the height H of the transverse hole 31 is large enough, the guide rod 22 located in the transverse hole 31 will shake in the vertical direction. In this embodiment 1, since the guide hole 122 is inclined, the inclined hole wall of the guide hole 122 can limit the shaking of the guide rod 22 in the vertical direction, which is beneficial to ensure the stability of the guide rod 22, and then it is beneficial to improve the stability of the plate body 2, thereby improving the stability and reliability of the toilet chair of this embodiment 1.

[0075] For further information, see Figure 1 In order to improve comfort, a seat cushion 23 is fixedly installed on the top surface of the two plate bodies 2, and the seat cushion 23 can be a latex pad or a sponge pad.

[0076] Embodiment 2:

[0077] This embodiment 2 is further improved on the basis of embodiment 1:

[0078] See also Figure 1 and Figure 2 A support rod 24 is fixedly installed on the two plate bodies 2 on the side facing away from each other, and a handrail plate 241 is fixedly installed on the upper end of the support rod 24.

[0079] When the lifting mechanism is used to drive the two plate bodies 2 to lift, the two plate bodies 2 drive the support rods 24 and the armrest boards 241 to lift together, which can help the user to hold the armrest boards 241 for support when getting up, making it more convenient for the user to stand.

[0080] See also Figure 3 A gripping rod 242 is fixedly mounted at the front end of each of the two armrest plates 241 .

[0081] When the two boards 2 assist the user to stand, the boards 2 are in an inclined state, and the gripping rod 242 at the front end of the armrest board 241 is in a vertical state with the board 2, so the gripping rod 242 at the front end of the armrest board 241 is more convenient for the user to grasp and leverage, making the toilet chair of this embodiment 2 more convenient to use.

[0082] See also Figure 1 , Figure 2 and Figure 7 , the rear ends of the two armrest plates 241 are fixedly installed with a pin shaft 243, and a fixed back plate 244 is rotatably installed on the pin shaft 243. The fixed back plate 244 is an arc-shaped plate, and the concave side of the fixed back plate 244 is away from the guide frame 12. A sliding cavity 2441 is provided inside the fixed back plate 244, and a limiting hole 2442 is provided on the top of the fixed back plate 244, and the limiting hole 2442 is connected with the sliding cavity 2441. A movable back plate 245 is provided between the two fixed back plates 244, and the movable back plate 245 is also an arc-shaped plate, and the concave side of the movable back plate 245 is also away from the guide frame 12. The movable back plate 245 is slidably matched with the sliding cavity 2441, and a limiting pin 2451 is fixedly installed on the top of the movable back plate 245, and the limiting pin 2451 is slidably matched with the limiting hole 2442.

[0083] When the two plates 2 lift the patient's buttocks upward, the two plates 2 drive the fixed back plate 244 and the movable back plate 245 to lift together. When the two plates 2 are lifted, the rear ends of the two plates 2 open, the two plates 2 drive the two fixed back plates 244 away from each other, the movable back plate 245 slides outward from the inside of the sliding cavity 2441 of the fixed back plate 244, and the limiting pin 2451 slides in the limiting hole 2442. The fixed back plate 244 and the movable back plate 245 can adapt to the opening action of the rear ends of the two plates 2.

[0084] On the contrary, when the two plates 2 fall back onto the base 1, the two plates 2 drive the two fixed back plates 244 and the movable back plates 245 to fall back together. When the two plates 2 fall back, the rear ends of the two plates 2 approach each other, the two plates 2 drive the two fixed back plates 244 to approach each other, the movable back plates 245 slide into the sliding cavity 2441 of the fixed back plates 244, and the limiting pins 2451 slide in the opposite direction in the limiting holes 2442. This allows the fixed back plates 244 and the movable back plates 245 to adapt to the movement of the rear ends of the two plates 2 approaching each other.

[0085] The arrangement of the fixed back plate 244 and the movable back plate 245 facilitates the user to lean on the back plate when defecating, thereby improving the user's comfort. In addition, because the fixed back plate 244 and the movable back plate 245 can adapt to the opening and approaching movements of the two plate bodies 2, the fixed back plate 244 and the movable back plate 245 can be lifted together with the two plate bodies 2, so that the fixed back plate 244 and the movable back plate 245 can avoid blocking the sight of the caregiver, and will not delay the caregiver from wiping the user's anus.

[0086] Embodiment 3:

[0087] This embodiment 3 is further improved on the basis of embodiment 1:

[0088] See also Figure 8 , Fig.11 and Fig.12 The middle part of the base 1 is provided with a receiving groove 14, which is connected to the toilet bowl 21. Fig.14 A plastic bag 141 is provided in the receiving groove 14 , the bag opening of the plastic bag 141 is sleeved on the top of the base 1 , and the plate body 2 is pressed on the bag opening of the plastic bag 141 .

[0089] The working principle of this embodiment 3 is as follows:

[0090] (1) When the user needs to defecate, a plastic bag 141 can be placed on the top of the base 1 in advance to facilitate the user to excrete feces or urine into the plastic bag 141.

[0091] (2) When the two plates 2 lift the user's buttocks to help the user stand up, the two plates 2 leave the top of the base 1, so that the plates 2 no longer press the mouth of the plastic bag 141, making it convenient for the caregiver to take away and discard the plastic bag 141. Then, the caregiver can put on a new plastic bag 141 for the user to use next time he or she defecates.

[0092] (3) When the two plates 2 fall back onto the base 1, the two plates 2 repress the plastic bag 141 to prevent the plastic bag 141 from falling off under the impact of feces or urine, thereby improving the reliability of the plastic bag 141 in receiving feces and urine.

[0093] According to the above working principle of the present embodiment 3, it can be known that the present embodiment 3 has the following effects:

[0094] In this embodiment 3, by sleeve-mounting a plastic bag 141 on the base 1, the user is allowed to excrete excrement into the plastic bag 141, which makes it convenient for caregivers to discard the plastic bag 141 containing excrement and clean up the excrement, thereby improving the convenience of use.

[0095] For further information, see Figure 8 A hook 15 is fixedly installed on the side of the base 1 , and a handle is provided at the bag opening of the plastic bag 141 , and the handle is hung on the hook 15 .

[0096] By hanging the handle of the plastic bag 141 on the hook 15 , the risk of the plastic bag 141 falling off can be further reduced, and the reliability of the plastic bag 141 being mounted on the base 1 can be further improved.

[0097] Embodiment 4:

[0098] This embodiment 4 is further improved on the basis of embodiment 3:

[0099] See also Figure 5 and Figure 6 , the interior of the two plate bodies 2 is provided with a piston cavity 25. The bottom of the two plate bodies 2 is provided with a piston hole 26, and the piston hole 26 is connected to the piston cavity 25. The two plate bodies 2 are provided with an air hole 27 at the upper end of the side close to each other, and the air hole 27 is arranged downward, and the air hole 27 is connected to the piston cavity 25.

[0100] See also Figure 5 and Figure 6A piston plate 251 is provided in the piston cavity 25, and the piston plate 251 is slidably matched with the piston cavity 25. A piston column 261 is fixedly installed at the bottom of the piston plate 251, and the piston column 261 is provided in the piston hole 26, and the piston column 261 is slidably matched with the piston hole 26. A stop block 2611 is fixedly installed at the bottom of the piston column 261, and the stop block 2611 abuts against the top of the base 1. A spring 2612 is sleeved on the piston column 261, and one end of the spring 2612 abuts against the stop block 2611, and the other end of the spring 2612 abuts against the bottom surface of the plate body 2.

[0101] The working principle of this embodiment 4 is as follows:

[0102] (1) First, before using the lifting mechanism to drive the two plates 2 to fall back, a new plastic bag 141 is placed on the top of the base 1.

[0103] Then, the lifting mechanism is used to drive the two plate bodies 2 to fall back, and the stop block 2611 under the plate body 2 gradually contacts the top of the base 1. The stop block 2611 overcomes the elastic force of the spring 2612 and approaches the bottom surface of the plate body 2, so that the piston column 261 slides upward in the piston hole 26, and the piston plate 251 slides upward in the piston cavity 25. The piston plate 251 pushes the air in the piston cavity 25 out of the air hole 27, and the airflow discharged from the air hole 27 blows toward the plastic bag 141, so that the plastic bag 141 is blown open by the airflow.

[0104] When the plate body 2 falls back to the lowest position, the stop block 2611 abuts against the top of the base 1, and the spring 2612 is in a state of maximum compression.

[0105] (2) When the lifting mechanism drives the two plates 2 to lift, the stop block 2611 under the plate 2 is also lifted, and the spring 2612 gradually expands. As the spring 2612 expands, the spring 2612 pushes the stop block 2611 away from the bottom surface of the plate 2, so that the piston column 261 slides downward in the piston hole 26, and the piston plate 251 slides downward in the piston cavity 25. The air pressure in the piston cavity 25 decreases, allowing external air to enter the piston cavity 25 through the air hole 27, so that the plastic bag 141 can be opened by air flow when the plate 2 falls back next time.

[0106] When the two plates 2 are lifted, the caregiver is allowed to discard the plastic bag 141 sleeved on the top of the base 1 , and is allowed to sleeve a new plastic bag 141 on the top of the base 1 .

[0107] According to the above working principle of Example 4, it can be known that Example 4 has the following effects:

[0108] First, by setting the stop block 2611, the piston column 261, the piston plate 251, the spring 2612, the piston cavity 25, and the piston hole 26, when the two plate bodies 2 are lifted, the air in the piston cavity 25 can be replenished; when the two plate bodies 2 are lowered, the piston plate 251 pushes the air in the piston cavity 25 out of the air hole 27, and the air flow discharged from the air hole 27 blows toward the plastic bag 141, so that the plastic bag 141 can be opened by the air flow, thereby increasing the distance between the inner wall of the plastic bag 141 and the user, reducing the probability of the user's excrement splashing back to the user's private parts, and improving the comfort of use.

[0109] Second, because the airflow can open the plastic bag 141, there is no need for the caregiver to manually open the plastic bag 141, which can reduce the caregiver's labor intensity.

[0110] Thirdly, the blowing action of the airflow is linked with the lifting action of the plate body 2, and there is no need to use an additional power source to drive the blowing of the airflow, which is conducive to saving energy.

[0111] Embodiment 5:

[0112] In Example 4, when the plate body 2 falls back to the top of the base 1, only the stop block 2611 located under the plate body 2 can contact the top of the base 1. The stop block 2611 prevents the bottom of the plate body 2 from directly contacting the top of the base 1, so that most of the plate body 2 is in a suspended state, and the supporting effect of the plate body 2 needs to be improved.

[0113] In this regard, in this embodiment 5, see Figure 8 and Fig.11 The top surface of the base 1 is provided with a hidden groove 13, and the stop block 2611 abuts against the bottom of the hidden groove 13. By providing the hidden groove 13, when the two boards 2 fall back, the stop block 2611 abuts against the bottom of the hidden groove 13, allowing the bottoms of the two boards 2 to fall directly onto the top of the base 1, thereby improving the support reliability of the boards 2, and then improving the reliability of the user sitting on the boards 2.

[0114] Furthermore, when the plastic bag 141 is sleeved on the top of the base 1, the opening of the plastic bag 141 blocks the hidden groove 13. When the plate 2 falls back, the stop block 2611 abuts the opening of the plastic bag 141 against the bottom of the hidden groove 13, further reducing the risk of the plastic bag 141 falling off and further improving the stability of the plastic bag 141.

[0115] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
