Description

Technical Field

[0001] The present invention relates to the technical field of sanitary equipment, and particularly to a novel toilet that facilitates the sitting and standing up of the elderly and pregnant women. Background Art

[0002] With the improvement of the quality of life, people have gradually changed from squatting toilets to using more convenient and hygienic sitting toilets. The sitting toilet has also become a kind of sanitary ware installed in every household. The sitting toilet can provide support for the user's buttocks and thighs, and will not cause leg soreness or numbness due to squatting for a long time. It is more comfortable and convenient at the same time.

[0003] The height of the existing sitting toilets is fixed, and the toilet is immovable after installation. The user needs to sit on the toilet for convenience. During the process of sitting down for convenience, the user needs to squat down to adapt to the height of the toilet. However, for the elderly, pregnant women or patients with lumbar disc herniation and other people with weak waist and leg strength and inconvenient movement, whether it is from standing to sitting down for convenience or from standing up from the toilet after convenience, it is relatively difficult and often requires the help of others. For these special groups, it is very difficult to stand up from a sitting position without the follow-up of nursing staff, which brings great inconvenience to toileting.

[0004] At the same time, when using a sitting toilet to defecate, the puborectalis muscle of the human body will involve the rectum to a greater extent, resulting in a smaller anorectal angle and difficult defecation. Over time, it will lead to constipation and affect physical health.

[0005] The patent "A Lifting Assistance Device for a Sitting Toilet" with the application number 2016102171850 proposes an auxiliary mechanism that adjusts the link mechanism through a driving device to drive the toilet seat to move to a suitable height. However, when using this auxiliary mechanism, since there is no support point for the upper body of the user, the center of gravity of the user's body needs to be pressed on the link mechanism during the process of standing up to sitting down, making it difficult to maintain balance. There is still a certain safety risk for the elderly or pregnant women, and at the same time, it cannot solve the problem of unsmooth defecation caused by using a sitting toilet. Summary of the Invention

[0006] In order to solve the problems that the elderly, pregnant women and other groups have difficulty sitting and standing up when using a sitting toilet and the use of a sitting toilet leads to unsmooth defecation in the prior art, the present invention provides a novel toilet that facilitates the sitting and standing up of the elderly and pregnant women.

The front connecting plate 304 and the rear connecting plate 305 are respectively rotatably connected to the lower ends of the front support rod 301 and the rear support rod 302. By adjusting the rotation speed, forward and reverse rotation of the stepping motor 307, the front support rod 301 and the rear support rod 302 are driven to move, and finally the adjustment of the support seat ring 4 is realized.

[0032] During the use process, the state change of the support seat ring 4 is as follows:

[0033] 1. From the no-load and horizontal state to the no-load and inclined state

[0034] When the support seat ring 4 is not in use, it is in an unloaded and horizontal state. At this time, the horizontal height of the support seat ring 4 from the ground is 542 mm, the height from the pedal 503 is 450 mm, the motor speed is zero, and the distance between the sliders of the two linear guide rail sets is 660 mm; when in use, the user presses the auxiliary sitting-up button on the controller 8, the stepping motor 307 rotates forward at a speed of 200 r / min, and the stepping motor 307 drives the sliders of the linear guide rail set 9 to move towards each other through the front connecting plate 304 and the rear connecting plate 305, with a moving speed of 33 mm / s. The front support rod 301 and the rear support rod 302 rotate. At this time, the distance between the lower ends of the front support rod 301 and the rear support rod 302 is reduced to 450 mm, the height of the lower edge of the support seat ring 4 from the ground is 570 mm, the height from the pedal 503 is 480 mm, and the support seat ring 4 becomes an unloaded and inclined state.

[0035] 2. From the loaded and inclined state to the loaded and horizontal state

[0036] The user holds the handle 702 with both hands and places the body center of gravity on the support seat ring 4. The support seat ring 4 changes from the unloaded and inclined state to the loaded and inclined state, and then the user presses the auxiliary sitting-up button on the controller 8. The stepping motor 307 rotates reversely at a speed of 120 r / min, and the stepping motor 307 drives the sliders of the linear guide rail set 9 to move away from each other through the front connecting plate 304 and the rear connecting plate 305, with a moving speed of 20 mm / s. The front support rod 301 and the rear support rod 302 rotate and drive the support seat ring 4 to rotate. Finally, the support seat ring 4 rotates to the loaded and horizontal state and is located above the toilet body 1. The user sits steadily on the toilet for convenience. At this time, the horizontal height of the support seat ring 4 from the ground is 542 mm, the height from the pedal 503 is 450 mm, the motor speed is zero, and the distance between the lower ends of the front support rod 301 and the rear support rod 302 is 600 mm.

[0037] 3. From the loaded and horizontal state to the loaded and inclined state

[0038] When the user needs to get up after using the toilet, the user presses the auxiliary sitting-up button on the controller 8. The stepping motor 307 rotates forward at a speed of 120 r / min, and the stepping motor 307 drives the sliders of the linear guide rail set 9 to move towards each other through the front connecting plate 304 and the rear connecting plate 305, with a moving speed of 20 mm / s. The front support rod 301 and the rear support rod 302 rotate and drive the support seat ring 4 to rotate. Finally, the support seat ring 4 rotates to the loaded and inclined state. At this time, the height of the lower edge of the support seat ring 4 from the ground is 570 mm, the height from the pedal 503 is 480 mm, the motor speed is zero, and the distance between the lower ends of the front support rod 301 and the rear support rod 302 is 450 mm.

[0039] 4. From no-load and inclined state to no-load and horizontal state

[0040] After use, the user gets up by holding the handle 702, and the supporting seat ring 4 becomes in a no-load and inclined state. The user releases the handle 702 and leaves the toilet body 1, then presses the auxiliary sitting-up button of the controller 8. The stepping motor 307 rotates in reverse, and its speed drives the slider of the linear guide rail set 9 to move in a direction away from each other through the front connecting plate 304 and the rear connecting plate 305. The front support rod 301 and the rear support rod 302 rotate and drive the supporting seat ring 4 to rotate. Finally, the supporting seat ring 4 rotates to a no-load and horizontal state.

[0041] As Figure 6 shown, during the process of the user using the toilet, the height of the footrest 503 can be adjusted according to the user's habit to adjust the sitting position on the toilet. Specifically, the user presses the pedal lifting button on the controller 8, the wireless Bluetooth module of the control component 6 receives the signal, and transmits the action signal to the electric push rod 505. The output end of the electric push rod 505 extends, driving the rotating shaft 504 hinged to it to move. The two ends of the rotating shaft 504 are arranged in the sliding grooves at the rear of the fixed bracket 501 and are connected to the lower ends of the pedal support rods 502. The rotating shaft 504 makes a linear motion in the sliding groove, driving the pedal support rods 502 on both sides to make a planar motion. The pedal support rods 502 on both sides drive the footrest 503 to move during the movement, and finally the height of the footrest 503 can be adjusted, realizing the adjustment of the sitting position on the toilet. Specifically, the extension range of the electric push rod 505 in this embodiment is 0 - 100 mm, and the height range between the footrest 503 and the base 2 is 0 - 150 mm.

[0042] When the user needs help in an emergency during use, the user presses the emergency call button on the controller 8, and the alarm sounds to remind the nearby people to provide assistance.

[0043] The above embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
