Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of toilet accessories, specifically relating to a toilet seat flipping device. Background Technology
[0002] With advancements in technology, various types of smart toilets have emerged on the market. These toilets feature automatic flushing, automatic lid opening, and heated seats, making them popular with consumers. However, in the current environment, smart toilets are still several times more expensive than ordinary flush toilets, and over 80% of households, offices, and public places still use traditional flush toilets. With traditional flush toilets, the toilet seat doesn't automatically spring back after use. Whether in homes or public places, this lack of automatic spring back can lead to contamination and make it difficult to maintain hygiene.
[0003] In existing technologies, there are two main types of solutions to ensure the cleanliness and hygiene of toilet seat covers. One type is the smart toilet, which can automatically flip the toilet seat, reducing toilet seat contamination, but it is expensive and has a low adoption rate. The other type involves adding accessories to traditional flush toilets. These accessories allow for the flipping of the toilet seat without manual contact, aiming to avoid manual operation. However, they cannot flip up the toilet seat, thus failing to provide cleanliness and hygiene protection for the toilet seat and cannot reduce bacterial infection. Utility Model Content
[0004] The purpose of this utility model is to propose a toilet seat flip-up device to solve the problems of high cost and low adoption rate of smart toilets and the inability of traditional ordinary flush toilets to automatically flip up the toilet seat after use by adding accessories.
[0005] To achieve the above objectives, the present invention provides a toilet seat lifting device comprising:
[0006] An external shaft that is coaxially and fixedly connected to one end of the toilet seat's rotating shaft;
[0007] The outer casing located on one side of the toilet;
[0008] A rotating shaft is rotatably connected to both ends and the upper end of the outer casing via bearings. The rotating shaft and the external shaft are driven to transmit rotational motion to each other through a transmission mechanism.
[0009] An electromagnet is disposed on the outer circumference of the flipping shaft;
[0010] A counterweight block located below the electromagnet, the two ends of which are fixedly connected to the flipping shaft by a connecting rope;
[0011] The circuit controls the on / off switching of the electromagnet. The circuit includes a power supply, a first switch, a time relay, and a second switch connected in series, as well as an electromagnet, a time relay, and a power supply connected in series. The first switch is a normally open switch, and the second switch is a normally closed switch. When the toilet seat is flipped down, the first switch is closed, the circuit is connected, and the electromagnet becomes magnetic. When the toilet seat is fully lowered and the user sits on it, the second switch is opened. After the user leaves, the second switch is closed, the time relay briefly disconnects after a predetermined time, and the electromagnet loses its magnetism.
[0012] The transmission mechanism includes:
[0013] A first gear fixedly mounted on the external shaft;
[0014] And a second gear fixedly disposed at the end of the flipping shaft, wherein the first gear and the second gear mesh.
[0015] The first gear is a large gear, and the second gear is a small gear.
[0016] The first gear is a gear with a slit on its outer circumference, and the first gear contacts the first switch to control opening and closing.
[0017] The first switch includes:
[0018] First fixed conductive sheet;
[0019] A second fixed conductive sheet is coaxially spaced from the first fixed conductive sheet at one end;
[0020] A conductive rod with one end rotatably engaged with one side of the first fixed conductive sheet;
[0021] A first spring is connected between the middle of the conductive rod and the first fixed conductive plate. In its natural state, the other end of the conductive rod is in contact with the second fixed conductive plate and closed. One corner of the outer circumferential tangent of the first gear is in contact with the conductive rod. The rotation of the first gear adjusts the force that tightens the conductive rod, thereby opening or closing the conductive rod.
[0022] The second switch is a pressure switch.
[0023] The second switch includes:
[0024] Fixed wall;
[0025] The middle position is a rotating engagement rod with the fixed wall, and one end of the rod contacts the lower end face of the toilet seat when it is lowered.
[0026] A second spring is connected between the other end of the starting rod and the fixed wall.
[0027] The beneficial effects of this utility model are as follows: This utility model provides a toilet seat flipping device that achieves bidirectional motion through the action of an electromagnet and a counterweight, as well as the downward flipping of the toilet seat. The electromagnet is controlled by a circuit to determine whether it is energized. When the user stands up from the toilet, the second switch is activated, the time relay is delayed and then disconnected, breaking the circuit. The electromagnet is de-energized and loses its magnetic force, moving downwards under the weight of the counterweight. This movement, via a connecting rope, drives the flipping shaft to rotate, which in turn drives the toilet seat to rotate around the shaft and flip upwards, achieving the purpose of automatic toilet seat flipping. Once the toilet seat returns to a vertical position, the first gear engages the first switch, disconnecting the circuit and closing the time relay, preparing for the next use. It can be reused repeatedly without external manual control. This avoids the problem of contamination caused by not flipping the toilet seat after use. This design adds an accessory to the traditional flush toilet, allowing the toilet seat to be flipped up without manual contact. This automatic flipping eliminates the need for manual flipping, making it more convenient for subsequent users, especially male users. This helps maintain the cleanliness and hygiene of toilet seats in public places and homes, reducing the risk of bacterial infection. Attached Figure Description

[0033] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0034] See Figures 1-4 The toilet seat 1 flipping device of this utility model includes:
[0035] An external shaft 3 is fixedly connected coaxially to one end of the toilet seat 1's rotating shaft 2;
[0036] The outer casing 4 is located on one side of the toilet;
[0037] A rotating shaft 6 is rotatably connected to both ends and the upper end of the outer shell 4 via bearings 5. The rotating shaft 6 and the external shaft 3 are driven to transmit rotational motion to each other through a transmission mechanism.
[0038] An electromagnet 7 is disposed on the outer circumference of the flipping shaft 6;
[0039] The counterweight block 8 is located below the electromagnet 7. The two ends of the counterweight block 8 are fixedly connected to the flipping shaft 6 via a connecting rope 9. When the electromagnet 7 is energized, the length of the connecting rope 9 ensures that the electromagnet 7 does not attract the counterweight block 8 when it is in a natural hanging state.
[0040] The circuit controls the on / off switching of the electromagnet 7. The circuit includes a power supply, a first switch 12, a time relay 14, and a second switch 13 connected in series, as well as the electromagnet 7, time relay 14, and power supply connected in series. The first switch 12 is a normally open switch, and the second switch 13 is a normally closed switch. When the toilet seat 1 is flipped downwards, the first switch 12 closes, the circuit is connected, and the electromagnet 7 becomes magnetic. When the toilet seat 1 is fully lowered and the user sits on it, the second switch 13 opens. After the user leaves, the second switch 13 closes, the time relay 14 briefly opens after a predetermined time, and the electromagnet 7 loses its magnetism. The a and b contacts of the time relay 14 are connected to a magnetic coil, and the c and d contacts are normally closed. When the second switch 13 is closed, the circuit is connected, the time relay 14 starts timing, and briefly opens after the time is reached, de-energizing the electromagnet 7.
[0041] The transmission mechanism includes:
[0042] The first gear 10 is fixedly mounted on the external shaft 3;
[0043] And a second gear 11 fixedly disposed at the end of the flip shaft 6, wherein the first gear 10 and the second gear 11 mesh.
[0044] The first gear 10 is a large gear, and the second gear 11 is a small gear.
[0045] The first gear 10 is a gear with a slit on its outer circumference, and the first gear 10 and the first switch 12 are in contact to control opening and closing.
[0046] The first switch 12 includes:
[0047] First fixed conductive sheet 15;
[0048] A second fixed conductive sheet 16 is coaxially spaced from the first fixed conductive sheet 15 at one end;
[0049] A conductive rod 17 with one end rotatably engaged with one side of the first fixed conductive sheet 15;
[0050] A first spring 18 is connected between the middle of the conductive rod 17 and the first fixed conductive sheet 15. In its natural state, the other end of the conductive rod 17 is in contact with the second fixed conductive sheet 16 and closed. One corner of the outer circumferential tangent of the first gear 10 is in contact with the conductive rod 17. The rotation of the first gear 10 adjusts the force that presses against the conductive rod 17 to open or close the conductive rod 17.
[0051] The second switch 13 is a pressure switch; pressing it down cuts off the power, and lifting it opens the circuit.
[0052] The second switch 13 includes:
[0053] Fixed wall 19;
[0054] The starting rod 20 is rotatably engaged with the fixed wall 19 in the middle position, and one end of the starting rod 20 contacts the lower end face of the toilet seat 1 when it is lowered.
[0055] A second spring 21 is connected between the other end of the starting rod 20 and the fixed wall 19.
[0056] When the toilet seat 1 falls, the lower end of the toilet seat 1 contacts one end of the actuator 20, which is insufficient to overcome the elastic force of the second spring 21. When the user sits down, the pressure increases, pressing the actuator 20 and the second switch 13 is turned off. When the user stands up, the pressure decreases, the actuator 20 is reset under the action of the second spring 21, and the second switch 13 is turned on.
[0057] The working process of this utility model is as follows:
[0058] In the initial state, the toilet seat 1 is in the flipped-up upright position, the counterweight 8 is in the lowest position, the first gear 10 is pressing against the first switch 12, so that the first switch 12 is in the open state. At this time, the second switch 13 is in the conducting state, the time relay 14 is also in the conducting state, and the circuit is in the open state. When the toilet needs to be used, the user manually flips the toilet seat 1 downwards. The seat shaft 2 and the external shaft 3 drive the flipping shaft 6 to rotate through the transmission mechanism. The connecting rope 9 begins to wind around the flipping shaft 6, the counterweight 8 rises, the first gear 10 disengages from the first switch 12, the first switch 12 is turned on, the circuit is energized, the electromagnet 7 becomes magnetic, and attracts the counterweight 8.
[0059] When the toilet seat 1 is flipped down to its lowest position, the weight of the toilet seat 1 is insufficient to trigger the second switch 13, and the circuit remains in the conducting state, thus preventing the toilet seat 1 from being flipped up due to the action of the counterweight block 8 even when no one is sitting on it.
[0060] When the user sits on the toilet seat 1, the second switch 13 is opened by pressure, and the circuit is broken. At this time, because the user is sitting on it, the counterweight block 8 cannot fall.
[0061] When the user stands up, the second switch 13 loses pressure and becomes conductive, and the electromagnet 7 continues to attract the counterweight block 8; the time relay 14 disconnects after the set time, the circuit is broken, the electromagnet 7 loses its magnetism, and the counterweight block 8 drops due to gravity, driving the flipping shaft 6 to rotate through the connecting rope 9. The rotation of the flipping shaft 6 drives the washer rotating shaft 2 to rotate through the transmission mechanism and the external shaft 3, thereby achieving the purpose of flipping the toilet seat 1 upward.
[0062] After the toilet seat 1 flips upward to its limit position, the first gear 10 on the external shaft 3 blocks the first switch 12, the first switch 12 is turned off, and the time relay 14 briefly disconnects after the person stands up before returning to its initial state.
