Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.

Fig. 1 illustrates the structure of a waterless toilet according to one embodiment of the present invention.

As shown in fig. 1, the waterless toilet provided by the embodiment of the present invention includes: the side wall comprises a side wall 1, a valve plate 2 and a valve plate rotation driving mechanism 3, wherein the side wall 1 is provided with an excrement inlet 11 and an excrement outlet (not shown in the figure), the valve plate 2 is obliquely arranged at the excrement outlet relative to a horizontal plane to close the excrement outlet, the side wall 1 plays a role in preventing excrement from splashing everywhere, meanwhile, the effect of accumulating the excrement falling on the side wall 1 to the valve plate 2 is achieved, when the valve plate 2 rotates downwards to open the excrement outlet, the excrement slides down from the valve plate 2 to be collected, and then the valve plate rotation driving mechanism 3 drives the valve plate 2 to rotate upwards to close the excrement outlet.

In one example of the present invention, the side panel 1 may be a cylindrical structure, specifically a right circular cylinder or an elliptic cylinder, and is formed by closing a curved side panel end to end. The side wall 1 can also be a prism structure and is formed by encircling at least three side plates.

In another example of the present invention, the caliber of the excrement outlet is smaller than that of the excrement inlet 11, so that the side plates of the side wall 1 are not perpendicular to the horizontal plane, thereby forming a funnel-shaped structure.

In order to prevent the excrement from being stained on the valve plate 2 or the side wall 1, the surfaces of the valve plate 2 and the side wall 1, which are contacted with the excrement, are super-hydrophobic surfaces. In one example of the invention, the super-hydrophobic coating with a micro-nano structure is coated on the surfaces of the valve plate 2 and the side wall 1, so that the surfaces of the valve plate 2 and the side wall 1 have super-hydrophobic characteristics, and excrement cannot be attached to the valve plate 2 or the side wall 1 by simulating a lotus effect.

The invention determines that no excrement residue exists on the surface of the valve plate 2 through the super-hydrophobic surface, and the mode replaces water flushing to finish cleaning the valve plate 2, thereby achieving the purpose of saving water resources.

Fig. 2 shows the structure of a flap plate rotation driving mechanism according to an embodiment of the present invention.

As shown in fig. 2, the flap plate rotation driving mechanism 3 includes a first rotating shaft 31, a first bearing seat 32 and a weight box 33, the first bearing seat 32 is fixedly connected with the side gusset 1, a groove is formed on the first bearing seat 32, the first rotating shaft 31 is assembled in the groove of the first bearing seat 32, and the weight box 33 is fixedly connected with the first rotating shaft 31 and rotates synchronously with the first rotating shaft 31.

When excrement is not accumulated on the valve plate 2, the valve plate 2 and the weight box 33 respectively generate torques with opposite directions on the first rotating shaft 31 through self gravity, and the torque generated by the weight box 33 on the first rotating shaft 31 is larger than the torque generated by the valve plate 2 on the first rotating shaft 31, so that the valve plate 2 is attached to the excrement outlet, and the excrement outlet is closed.

When the valve plate 2 accumulates excrement and the torque generated by the valve plate 2 and the excrement integrally to the first rotating shaft 31 is larger than the torque generated by the weight box 33 to the first rotating shaft 31, the excrement drives the valve plate 2 to rotate downwards to open the excrement outlet. Because the surface that shutter board 2 and excrement contact is super hydrophobic surface, and has certain angle relative to the horizontal plane, the excrement passes through self gravity and follows the super hydrophobic surface gliding of shutter board 2, and it is collected to slide down from shutter board 2.

After the excrement slides up from the valve plate 2, the torque generated by the valve plate 2 to the first rotating shaft 31 is smaller than the torque generated by the weight box 33 to the first rotating shaft 31 again, the weight box 33 drives the first rotating shaft 31 to rotate, the first rotating shaft 31 drives the valve plate 2 to rotate upwards, and the excrement outlet is closed again.

The invention realizes the opening or closing of the excrement outlet by a pure mechanical structure mode instead of an electric energy driving mode, thereby achieving the purpose of saving electric energy.

The waterless toilet provided by the invention does not need to use water resources and electricity resources, so that the application area is wider, and the waterless toilet is suitable for being built in areas without water or without electricity or without water or without electricity.

If the shutter plate 2 and the weight box 33 are directly and fixedly connected with the first rotating shaft 31, the installation is difficult due to the limitation of the installation space. Therefore, the valve plate 2, the weight box 33 and the first rotating shaft 31 are fixedly connected through two connecting plates, namely the first rotating shaft 31 is fixedly connected with the valve plate 2 through a first connecting plate 34, and the first rotating shaft 31 is fixedly connected with the weight box 33 through a second connecting plate 35.

In one embodiment of the present invention, the first shaft 31 is integrally formed with the first and second connecting

plates

34 and 35.

In order to adjust the torque generated by the weight box 33 on the first rotating shaft 31, a strip-shaped adjusting hole is formed in the second connecting plate 35, a bolt 36 is fixed at the bottom of the weight box 33, and the bolt 36 penetrates through the strip-shaped adjusting hole downwards and slides in the strip-shaped adjusting hole. When the adjustment of the position of the weight box 33 is completed, the bolt 36 is locked to the second connecting plate 35.

In order to adjust the amount of torque generated from the weight box 33 to the first shaft 31 in real time during the opening or closing of the excreta outlet, the weight box 33 is inclined downward at a certain angle with respect to the horizontal plane, and a weight ball that can roll is placed in the weight box 33.

The purpose of the inclined horizontal surface of the weight box 33 is to always have a tendency to move away from the first rotation axis 31, and the farther the weight ball is from the first rotation axis 31, the greater the torque generated on the first rotation axis 31.

When the valve plate 2 does not accumulate excrement, the valve plate 2 can be tightly closed to the excrement outlet.

When excrement accumulated on the valve plate 2 is enough to enable the valve plate 2 to rotate downwards, the valve plate 2 drives the first rotating shaft 31 and the weight box 33 to rotate, the weight ball in the weight box 33 rolls towards the direction of the first rotating shaft 31, the rolling of the weight ball changes the force application point of the weight, the valve plate 2 rotates rapidly, and an excrement outlet is opened.

According to the invention, through the inclined arrangement of the weight box 33 and the rolling of the weight ball, the valve plate 2 rotates by a small angle to enable the force application point of the weight to be shifted, and meanwhile, the weight box 33 gradually inclines towards the valve plate 2, so that the rotating speed of the first rotating shaft 31 and the valve plate 2 is increased, and the excrement outlet is rapidly opened.

When excrement slides from the valve plate 2 under the action of gravity, the torque generated by the weight box 33 and the weight ball on the first rotating shaft 31 is larger than the torque generated by the valve plate 2 on the first rotating shaft 31 again, the first rotating shaft 31 rotates in the opposite direction, the weight box 33 gradually inclines in the opposite direction, the weight ball gradually moves in the direction away from the first rotating shaft 31, the valve plate 2 slowly rotates in the opposite direction until the weight ball rolls to the farthest end away from the first rotating shaft 31, and at the moment, the torque generated by the weight box 33 and the weight ball on the first rotating shaft 31 is the largest, so that the excrement outlet is tightly closed.

The waterless toilet provided by the invention further comprises a sealing pressure plate 4, wherein a sealing strip 5 is adhered to the bottom surface of the sealing pressure plate 4, and the sealing strip 5 forms a closed loop for sealing the excrement outlet. When the excrement outlet is not opened, the sealing strip 5 is pressed on the super-hydrophobic surface of the valve plate 2 through the sealing pressing plate 4, so that the excrement outlet is sealed, and the odor is prevented from being upwards diffused.

Because the excrement has a corrosion effect on the sealing strip 5, in order to avoid the excrement from contacting with the sealing strip 5 when sliding off the valve plate 2, the invention designs a sealing pressure plate rotating driving mechanism, when the valve plate 2 rotates downwards, the sealing pressure plate rotating driving mechanism drives the sealing pressure plate 4 to drive the sealing strip 5 to rotate upwards, so that the excrement is prevented from contacting with the sealing strip 5, and the sealing strip 5 is ensured not to be corroded by the excrement.

Fig. 3 shows the structure of a sealing platen rotation driving mechanism according to an embodiment of the present invention.

As shown in fig. 3, the sealing pressure plate rotation driving mechanism includes a second rotating shaft 61, a second bearing seat 62, a cam 63 and a driving plate 64, the second bearing seat 62 is fixedly connected with the side wall 1, the second bearing seat 62 is formed with a groove, the second rotating shaft 61 is assembled in the groove of the second bearing seat 62 and is fixedly connected with the driving plate 64, the driving plate 64 can rotate around the second rotating shaft 61, the cam 63 is installed at the end of the first rotating shaft 31 and rotates synchronously with the first rotating shaft 31, one end of the driving plate 64 is fixedly connected with one end of the sealing pressure plate 4, and the other end of the driving plate 64 is used for contacting with the cam 63.

When the valve plate 2 rotates downwards to open the excrement outlet, the first bearing 31 and the cam 63 are driven to rotate, the protruding part of the cam 63 presses the driving plate 64 to rotate around the second rotating shaft 61, the sealing pressing plate 4 is driven to rotate upwards, the sealing strip 5 is driven to be separated from the super-hydrophobic surface of the valve plate 2 and located above the valve plate 2, and excrement cannot contact with the sealing strip 5 when sliding off.

According to the invention, through the structural design of the sealing pressure plate rotation driving mechanism, the linkage of the valve plate 2 and the sealing pressure plate 4 is realized, and the rotation directions of the valve plate 2 and the sealing pressure plate 4 are opposite, so that the sealing strip 5 is ensured not to be polluted.

When the valve plate 2 closes the excrement outlet, the sealing strip 5 can also play a role in shock absorption, so that the impact of the valve plate 2 on the side wall 1 is reduced, and noise is not generated.

Fig. 4 shows a partial enlargement of the structure of fig. 3.

As shown in fig. 4, a third bearing seat 65 is fixed to the driving plate 64, a third rotating shaft 66 is mounted on the third bearing seat 65, a bushing 67 is sleeved on the third rotating shaft, the bushing 67 contacts with the protruding portion of the cam 63, and the bushing 67 plays two roles, namely, the overall size of the cam 63 is reduced, and the bushing 67 contacts with the protruding portion of the cam 63 more smoothly through the rotation of the bushing 67.

There is a special case of the present invention: the flap 2 accumulates excrement but is not sufficient to rotate the flap 2 to open the excrement outlet. In order to collect excrement, a standby plate 68 is fixedly connected to the cam 63, and when the standby plate 68 is applied with force, the first bearing 31 is driven to rotate, and the first bearing 31 drives the shutter plate 2 to rotate downwards to open the excrement outlet, so that the excrement is collected actively.

In a preferred embodiment, the standby plate 68 is fixedly attached to the cam 63 near the center of rotation, and the footrest requires only a small vertical stroke to achieve a large opening angle of the excrement outlet.

In a specific example of the present invention, the standby plate 68 is applied with force by a foot pedal device, which is a foot pedal device used in a water toilet, and acts on the standby plate 68 when a user steps on the foot pedal device.

FIG. 5 shows the mating relationship of the side seal to the sealing strip in accordance with one embodiment of the present invention.

As shown in fig. 5, the sealing press plate 4 is a frame-shaped structure, and an accommodating groove is formed on the inner side of the sealing press plate 4 along the length direction, and the sealing strip 5 is accommodated in the accommodating groove, so that the sealing press plate 4 wraps the sealing strip in the accommodating groove, and the sealing strip 5 is prevented from dust.

In order to avoid the interference between the sealing pressure plate 4 and the sealing strip 5 and the side wall 1 in the rotating process, a circle of side sealing strip 11 is fixed along the circumferential direction of the side wall 1, the side sealing strip 11 is in contact with the sealing strip 5, and the vertical surface of the side sealing strip 11 in contact with the sealing strip 5 is an inclined surface.
