[0017] The beneficial effects of the present invention are:

[0018] 1. The pedal mechanism of the present invention can drive the transmission mechanism to move, and the transmission mechanism drives the toggle mechanism to tilt. The toggle rod on the toggle mechanism can drive the cover plate to move through the toggle groove. The cover plate is sleeved in the shell, and the cover plate moves along a determined path driven by the toggle mechanism to ensure that the cover plate can cover or open the opening of the shell. By stepping on the pedal mechanism, the opening and closing of the cover plate can be controlled, and the operation is convenient. The opening of the squat toilet is easy to seal and open, so that after the opening of the squat toilet is sealed by the cover plate, the bathroom floor is flat and beautiful. In addition, after the cover plate is unfolded, it can prevent the user from contacting the squat pit when slipping, and ensure the safety of children, the elderly or other animals.

[0019] 2. When the toggle mechanism moves one of the cover plates, the rack on the cover plate drives the gear to rotate, and the gear drives the rack on the other cover plate to move. Since the opening and closing racks on the two cover plates are arranged on both sides of the gear, the two racks move in opposite directions, so that the two cover plates can move toward or away from each other, realizing the closing or opening of the squat toilet opening by the cover plate, which is reliable.

[0020] 3. The pedal mechanism can drive the transmission rod to move through the shift fork, and the transmission rack on the transmission rod can drive the toggle gear to rotate. When the toggle gear rotates, the toggle rod on the toggle gear moves in the toggle groove on the cover plate and pushes the cover plate to move linearly. Therefore, the cover plate can be driven to move only by driving the transmission rod to move linearly through the pedal mechanism, and the moving direction of the cover plate is perpendicular to the moving direction of the transmission rod, which is convenient for the user to step on the pedal mechanism in the layout direction of the squat toilet, which is convenient for operation. When the transmission rod returns to its position, the reset spring can pull the transmission rod to reset, ensuring that the transmission mechanism can be repeatedly driven and the reliability of the present invention is ensured.

[0021] 4. The two ends of the pulling mechanism are respectively sleeved in the guide groove of the first guide rail and the guide groove of the second guide rail. When the foot steps on the pedal or the guide plate, the pulling mechanism can move into the groove of the heart-shaped guide groove. At this time, the pulling mechanism drives the transmission mechanism to move to the front end, and the transmission mechanism drives the toggle mechanism to rotate counterclockwise. The toggle mechanism toggles the cover plate to move, and the cover plate can seal the opening of the squat toilet. When the pedal or the guide plate is driven by the foot and the pulling mechanism moves to the convex part of the heart-shaped guide groove, the transmission mechanism moves in the opposite direction, and the toggle mechanism rotates clockwise. The toggle mechanism toggles the cover plate to move, and the cover plate can open the opening of the squat toilet, which is easy to operate.

[0022] 5. When the foot is removed from the pedal or guide plate, the torsion spring can automatically drive the pedal to rotate, and the pulling mechanism can automatically move to the groove or convex part of the heart-shaped guide groove. When the cover needs to be opened or closed, the pedal or guide plate is stepped on by foot without pushing the pedal or guide plate in the opposite direction, which simplifies the operation and is more convenient to use.

[0023] 6. In one direction, descending steps are sequentially arranged between the four sections of the sub-guide grooves, so that the pulling mechanism only moves in one rotation direction and does not move backward. When the foot is stepped on the pedal mechanism, the end of the pulling mechanism can easily move along the descending step to the next sub-guide groove, so the movement of the pulling mechanism is more accurate and reliable. Therefore, the present invention can ensure that when the user steps on the pedal mechanism, the cover plate is opened or closed, and when the user steps on the pedal mechanism again, the cover plate is easy to move and easy to use.

[0042] Example 1

[0043] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the coverable squat toilet of this embodiment includes a shell body 1, a water inlet pipe 2 and a drainage elbow 3 are connected to the bottom of the shell body 1, at least one cover plate 4 is sleeved in the shell body 1, one of the cover plates 4 is provided with a toggle groove 41, a toggle mechanism 5 is installed in the shell body 1, a toggle rod 51 is provided on the toggle mechanism 5, and the toggle rod 51 is sleeved in the toggle groove 41; the shell body 1 is also sleeved with a transmission mechanism 6 for driving the toggle mechanism 5 to rotate, the other end of the transmission mechanism 6 is connected to a foot pedal mechanism 7 for driving the transmission mechanism 6 to move linearly, and the foot pedal mechanism 7 is installed on the shell body 1.

[0044] The pedal mechanism 7 of the present invention can drive the transmission mechanism 6 to move, and the transmission mechanism 6 drives the toggle mechanism 5 to tilt. The toggle rod 51 on the toggle mechanism 5 can drive the cover plate 4 to move through the toggle groove 41. The cover plate 4 is sleeved in the shell 1, and the cover plate 4 moves along a determined path driven by the toggle mechanism 5 to ensure that the cover plate 4 can cover or open the opening of the shell 1. By stepping on the pedal mechanism 7, the opening and closing of the cover plate 4 can be controlled, and the operation is convenient. The opening of the squat toilet is convenient to seal and open, so that after the opening of the squat toilet is sealed by the cover plate 4, the bathroom floor is flat and beautiful.

The opening and closing racks 42 on the two cover plates 4 are meshed with the gear 43, and the opening and closing racks 42 on the two cover plates 4 are arranged on both sides of the gear 43.

[0046] When the toggle mechanism 5 toggles one of the cover plates 4 to move, the rack on the cover plate 4 drives the gear 43 to rotate, and the gear 43 drives the rack on the other cover plate 4 to move. Since the opening and closing racks 42 on the two cover plates 4 are arranged on both sides of the gear 43, the two racks move in opposite directions, so that the two cover plates 4 can move toward or away from each other, realizing the closing or opening of the opening of the squat toilet by the cover plate 4, and realizing reliability.

[0047] Furthermore, Figure 5 and Figure 6 As shown, the transmission mechanism 6 includes a transmission rod 61, which is sleeved in the shell 1, one end of the transmission rod 61 is connected to a fork 62, and the fork 62 is connected to the pedal mechanism 7; a transmission rack 63 is fixed on the transmission rod 61, and the toggle mechanism 5 includes a toggle gear 52, which is installed in the shell 1, the transmission rack 63 is meshed with the toggle gear 52, and the toggle rod 51 is fixed on the toggle gear 52; a return spring 64 is connected between the transmission rod 61 and the shell 1.

[0048] The pedal mechanism 7 can drive the transmission rod 61 to move through the shift fork 62, and the transmission rack 63 on the transmission rod 61 can drive the toggle gear 52 to rotate. When the toggle gear 52 rotates, the toggle rod 51 on the toggle gear 52 moves in the toggle slot 41 on the cover plate 4 and pushes the cover plate 4 to move linearly. Therefore, the cover plate 4 can be driven to move by only driving the transmission rod 61 to move linearly through the pedal mechanism 7, and the moving direction of the cover plate 4 is perpendicular to the moving direction of the transmission rod 61, which is convenient for the user to step on the pedal mechanism 7 in the arrangement direction of the squat toilet, and is convenient for operation. When the transmission rod 61 returns to its position, the reset spring 64 can pull the transmission rod 61 to reset, ensuring that the transmission mechanism 6 can be repeatedly driven and the reliability of the present invention is ensured.

[0049] Specifically, Figure 7 to Figure 9 As shown, the pedal mechanism 7 includes a bracket 71, which is installed on the shell 1, and the first guide rail 72 and the second guide rail 73 are respectively installed on the bracket 71; one end of the bracket 71 is hinged with a pedal 74, the other end of the pedal 74 is hinged with a guide plate 75, and the other end of the guide plate 75 is connected to a pulling mechanism 76, and the first guide rail 72 and the second guide rail 73 are both provided with a heart-shaped guide groove 8, and the two ends of the pulling mechanism 76 are respectively sleeved in the guide groove 8 of the first guide rail 72 and the guide groove 8 of the second guide rail 73, and the pulling mechanism 76 is rotatably connected to the transmission mechanism 6.

[0050] The two ends of the pulling mechanism 76 are respectively sleeved in the guide groove 8 of the first guide rail 72 and the guide groove 8 of the second guide rail 73.

When the cover 4 needs to be opened or closed, the pedal 74 or the guide plate 75 is stepped on by foot, and there is no need to push the pedal 74 or the guide plate 75 in the opposite direction, which simplifies the operation and is more convenient to use.

[0052] like Fig.10 As shown, the guide groove 8 of the first guide rail 72 includes four sections of sub-guide grooves connected in sequence, and descending steps are sequentially arranged between the four sections of sub-guide grooves in one direction; the pulling mechanism 76 includes a pulling tube 761, the pulling tube 761 is connected to the guide plate 75, the transmission mechanism 6 is rotatably connected to the pulling tube 761, and two guide shafts 762 are sleeved in the pulling tube 761, one end of one guide shaft 762 is sleeved in the guide groove 8 of the first guide rail 72, and one end of the other guide shaft 762 is sleeved in the guide groove 8 of the second guide rail 73, and a clamping spring 763 is connected between the two guide shafts 762.

[0053] In one direction, descending steps are sequentially arranged between the four sections of the sub-guide grooves, so that the pulling mechanism 76 only moves in one rotation direction and does not move backward. When the foot pedal mechanism 7 is stepped on, the end of the pulling mechanism 76 can easily move to the next sub-guide groove along the descending step, so the movement of the pulling mechanism 76 is more accurate and reliable. Therefore, the present invention can ensure that when the user steps on the foot pedal mechanism 7, the cover plate 4 is opened or closed, and when the foot pedal mechanism 7 is stepped on again, the cover plate 4 is easy to move, and it is easy to use.

[0056] The pedal mechanism 7 of the present invention can drive the transmission mechanism 6 to move, and the transmission mechanism 6 drives the toggle mechanism 5 to tilt. The toggle rod 51 on the toggle mechanism 5 can drive the cover plate 4 to move through the toggle groove 41. The cover plate 4 is sleeved in the shell 1, and the cover plate 4 moves along a determined path driven by the toggle mechanism 5 to ensure that the cover plate 4 can cover or open the opening of the shell 1. By stepping on the pedal mechanism 7, the opening and closing of the cover plate 4 can be controlled, and the operation is convenient. The opening of the squat toilet is convenient to seal and open, so that after the opening of the squat toilet is sealed by the cover plate 4, the bathroom floor is flat and beautiful. In addition, after the cover plate 4 is unfolded, it can prevent the user from contacting the squat pit when slipping, and ensure the safety of children, the elderly or other animals.

[0057] Furthermore, Figure 5 As shown, there are two cover plates 4, which are arranged on both sides of the opening of the shell 1. An opening and closing rack 42 is fixed on the cover plate 4, and a gear 43 is installed in the shell 1. The opening and closing racks 42 on the two cover plates 4 are meshed with the gear 43, and the opening and closing racks 42 on the two cover plates 4 are arranged on both sides of the gear 43.

[0058] When the toggle mechanism 5 toggles one of the cover plates 4 to move, the rack on the cover plate 4 drives the gear 43 to rotate, and the gear 43 drives the rack on the other cover plate 4 to move. Since the opening and closing racks 42 on the two cover plates 4 are arranged on both sides of the gear 43, the two racks move in opposite directions, so that the two cover plates 4 can move toward or away from each other, realizing the closing or opening of the opening of the squat toilet by the cover plate 4, and realizing reliability.

[0059] Furthermore, Figure 5 and Figure 6 As shown, the transmission mechanism 6 includes a transmission rod 61, which is sleeved in the shell 1, one end of the transmission rod 61 is connected to a fork 62, and the fork 62 is connected to the pedal mechanism 7; a transmission rack 63 is fixed on the transmission rod 61, and the toggle mechanism 5 includes a toggle gear 52, which is installed in the shell 1, the transmission rack 63 is meshed with the toggle gear 52, and the toggle rod 51 is fixed on the toggle gear 52; a return spring 64 is connected between the transmission rod 61 and the shell 1.

[0060] The pedal mechanism 7 can drive the transmission rod 61 to move through the shift fork 62, and the transmission rack 63 on the transmission rod 61 can drive the toggle gear 52 to rotate. When the toggle gear 52 rotates, the toggle rod 51 on the toggle gear 52 moves in the toggle slot 41 on the cover plate 4 and pushes the cover plate 4 to move linearly. Therefore, the cover plate 4 can be driven to move by only driving the transmission rod 61 to move linearly through the pedal mechanism 7, and the moving direction of the cover plate 4 is perpendicular to the moving direction of the transmission rod 61, which is convenient for the user to step on the pedal mechanism 7 in the arrangement direction of the squat toilet, and is convenient for operation. When the transmission rod 61 returns to its position, the reset spring 64 can pull the transmission rod 61 to reset, ensuring that the transmission mechanism 6 can be repeatedly driven and the reliability of the present invention is ensured.

[0061] Specifically, Figure 7 to Figure 10 As shown, the pedal mechanism 7 includes a bracket 71, which is mounted on the housing 1, and a first guide rail 72 and a second guide rail 73 are respectively mounted on the bracket 71; a pedal 74 is hingedly connected to one end of the bracket 71, and a guide plate 75 is hingedly connected to the other end of the pedal 74, and a pulling mechanism 76 is connected to the other end of the guide plate 75, and a heart-shaped guide groove 8 is provided in the first guide rail 72 and the second guide rail 73, and the two ends of the pulling mechanism 76 are respectively sleeved in the guide groove 8 of the first guide rail 72 and the guide groove 8 of the second guide rail 73, and the pulling mechanism 76 is rotatably connected to the transmission mechanism 6; the pedal 74 is connected to the bracket 71 A torsion spring 77 is connected; the guide groove 8 of the first guide rail 72 includes four sections of sub-guide grooves connected in sequence, and descending steps are arranged in sequence between the four sections of sub-guide grooves in one direction; the pulling mechanism 76 includes a pulling tube 761, the pulling tube 761 is connected to the guide plate 75, the transmission mechanism 6 is rotatably connected to the pulling tube 761, two guide shafts 762 are sleeved in the pulling tube 761, one end of one guide shaft 762 is sleeved in the guide groove 8 of the first guide rail 72, and one end of the other guide shaft 762 is sleeved in the guide groove 8 of the second guide rail 73, and a clamping spring 763 is connected between the two guide shafts 762.

[0062] The two ends of the pulling mechanism 76 are respectively sleeved in the guide groove 8 of the first guide rail 72 and the guide groove 8 of the second guide rail 73. When the pedal 74 or the guide plate 75 is stepped on, the pulling mechanism 76 can move into the groove of the heart-shaped guide groove 8. At this time, the pulling mechanism 76 drives the transmission mechanism 6 to move to the front end, and the transmission mechanism 6 drives the toggle mechanism 5 to rotate counterclockwise.

[0064] In one direction, descending steps are sequentially arranged between the four sections of the sub-guide grooves, so that the pulling mechanism 76 only moves in one rotation direction and does not move backward. When the foot pedal mechanism 7 is stepped on, the end of the pulling mechanism 76 can easily move to the next sub-guide groove along the descending step, so the movement of the pulling mechanism 76 is more accurate and reliable. Therefore, the present invention can ensure that when the user steps on the foot pedal mechanism 7, the cover plate 4 is opened or closed, and when the foot pedal mechanism 7 is stepped on again, the cover plate 4 is easy to move, and it is easy to use.

[0065] Working principle:

[0066] Assume that the toilet bowl cover is currently closed. At this time, the guide shaft 762 is at the starting position of the third sub-guide groove 38.

[0067] To open the cover plate 4, the user only needs to step on the pedal 74 or the guide plate 75 or step on the pedal 74 and the guide plate 75 at the same time, and the guide shaft 762 will move along the second guide rail 73 and the third sub-guide groove 38 of the first guide rail 72. When the guide shaft 762 moves to the end of the third sub-guide groove 38, the guide shaft 762 automatically jumps into the fourth sub-guide groove 48 under the elastic force of the compression spring 763. The guide groove 8 of the first guide rail 72 is divided into the first sub-guide groove 18, the second sub-guide groove 28, the third sub-guide groove 38, and the fourth sub-guide groove 48, which are divided into four sections in total, and are connected end to end to form a loop. There is a vertical descending step at each connection. After entering the next sub-guide groove from the previous section, it cannot return to the previous section and can only move in one direction. This goes back and forth, and after a cycle, it returns to the starting point. When the external force applied to the pedal 74 or the guide plate 75 is removed, the torsion spring 77 will push the pedal 74 to flip backward around the axis of the pedal 74, and the return spring 64 will push the transmission mechanism 6 to move. At this time, the guide shaft 762 of the pulling mechanism 76 moves along the fourth sub-guide groove 48 of the first guide rail 72. The transmission rack 63 on the transmission rod 61 will drive the toggle gear 52 to rotate, and the toggle rod 51 on the toggle gear 52 pushes one of the cover plates 4 to move outward. The opening and closing rack 42 on the cover plate 4 drives the gear 43 to rotate, and the gear 43 drives the rack on the other cover plate 4 to move, and then the other cover plate 4 moves accordingly. The two cover plates 4 move in opposite directions, and the opening of the squat toilet is opened. At this time, under the elastic force of the compression spring 763, the guide shaft 762 automatically jumps to the starting position of the first sub-guide groove 18.

[0068] If the user wants to close the cover plate 4, he only needs to step on the pedal 74, and the guide shaft 762 will move along the second guide rail 73 and the first sub-guide groove 18 of the first guide rail 72. At the same time, the guide plate 75 will push the transmission mechanism 6 to move, the reset spring 64 will automatically compress and generate elastic force, the transmission rack 63 will push the toggle gear 52 to move in the opposite direction, and the toggle rod 51 on the toggle gear 52 will push one cover plate 4 to move toward the middle of the squat toilet. Through the action of the rack and gear 43, the other cover plate 4 will also move toward the middle of the squat toilet. When the two cover plates 4 are closed, the guide shaft 762 automatically jumps to the starting position of the second sub-guide groove 28 under the elastic force of the compression spring 763. At this time, the force on the pedal 74 is released, and under the elastic force of the torsion spring 77 and the return spring 64, the guide shaft 762 moves along the second sub-guide groove 28, and when it moves to the end of the second sub-guide groove 28, it automatically jumps to the starting position of the third sub-guide groove 38 under the elastic force of the compression spring 763, completing the action of closing the two cover plates 4.
