Description

Technical Field

[0001] The invention belongs to the technical field of sanitary ware, and in particular relates to a sealed toilet cover and a toilet. Background Art

[0002] Toilets are divided into direct flush type and siphon type. The principle is: the direct flush type uses the impact force of water flow to flush away dirt; the siphon type uses the water level difference formed after the drainage pipe is filled with water to discharge dirt with the help of the siphon effect.

[0003] It is inevitable that the toilet will be clogged during use. When the toilet is clogged, it can only be cleaned manually, which is not only laborious but also smells bad, affecting environmental hygiene. In the final analysis, the common reason for toilet blockage is insufficient flushing force. According to the conventional design direction, the most effective way to increase the flushing force of the toilet is to increase the water tank capacity and then increase the flushing water pressure. However, this method will increase the user's use cost and the manufacturing cost of the toilet, and the uncontrolled use of water resources is not in line with the concept of sustainable development. Therefore, under the premise of saving water, increasing the pressure difference between the toilet cavity pressure and the atmospheric pressure to enhance the sewage discharge capacity is the development direction of the toilet.

[0004] The Chinese invention patent with the patent number of 201921687264.3 discloses "a kind of anti-blocking toilet", which is a toilet with a sealing ring on the toilet cover. When the toilet cover is buckled, the inner cavity of the toilet forms a closed space. After the water in the water tank leaks into the toilet cavity, the pressure increases and the excrement is flushed clean.

The remaining sewage is discharged by the pressure in the cavity and the clean tap water flushed out; at the same time, the bacteria are completely isolated from turning up and flowing into the room when the toilet is flushed. The current toilets start to discharge sewage only when the tap water touches the sewage surface, and the ability to flush sewage depends entirely on the amount of water flowing into the toilet and the water pressure. The toilet cover of the present invention can effectively reduce the amount of water used when flushing the toilet and improve the problem of toilet blockage, responding to the current development concept of green environmental protection. At the same time, the toilet cover has good sealing after closing, completely isolating bacteria from flowing into the room. BRIEF DESCRIPTION OF THE DRAWINGS

Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0034] The present invention provides a technical solution: a sealed toilet cover, such as Figure 1 , Figure 2 , Figure 3 As shown; it includes a connecting base 5, a seat ring 3, and a toilet cover 2. The connecting base 5 is arranged inside the toilet cover 2. Two groups of articulated arms are arranged on the connecting base 5, one group is arranged at each end of the connecting base 5; each group of articulated arms includes a lower main arm 6.1 and a lower auxiliary arm 6.2. Two groups of articulated arms are arranged on the inner wall of the toilet cover 2, one group is arranged on the left and right side walls, and each group of articulated arms includes an upper main arm 6.3 and an upper auxiliary arm 6.4. The upper main arm 6.3 and the lower main arm 6.1 are cross-arranged and hinged at the waist. The upper auxiliary arm 6.4 is hinged to the end of the lower main arm 6.1, and the lower auxiliary arm 6.2 is hinged to the end of the upper main arm 6.3. The hinge point of the upper main arm 6.3 and the lower main arm 6.1 is located on the right side of the intersection of the lines connecting the hinge points at both ends of each (refer to the attached Figure 2 The upper auxiliary arm 6.4 is close to the upper main arm 6.3 to avoid the bending of the upper main arm 6.3, and the lower auxiliary arm 6.2 is close to the lower main arm 6.1 to avoid the bending of the lower main arm 6.1. When the upper main arm 6.3, the lower main arm 6.1, the upper auxiliary arm 6.4 and the lower auxiliary arm 6.2 cooperate to lift the toilet cover 2, the toilet cover 2 has a tendency to flip, move to the left and lift at the same time, that is, the motion trajectory is an arc and accompanied by flipping, so that when the toilet cover 2 is closed, the edge is flush with the edge of the toilet seat and can be opened normally. The seat ring 3 is hinged with the connecting base 5, the seat ring 3 is scalable, and the seat ring 3 is stored in the toilet cover 2. The edge of the toilet cover 2 is provided with a sealing ring 4 to increase the sealing when in contact with the toilet seat.

[0035] like Figure 4 As shown; an air inlet hole 2.1 is provided on the toilet cover 2, and a one-way air valve 2.2 is installed at the air inlet hole 2.1. After the toilet is flushed, air enters the toilet cavity from the air inlet hole 2.1. The one-way air valve 2.2 is provided, and the gas can only flow in one direction, which prevents pressure release in the toilet cavity during flushing, and air is allowed to enter after the flushing is completed.

[0036] like Fig.10As shown; the seat ring 3 includes a left and right ring body, both of which are hinged to the connection base 5. A torsion push mechanism is arranged between the ring body 3.1 and the connection base 5. The torsion push mechanism is connected to the hinge shaft of the lower main arm 6.1 or the lower auxiliary arm 6.2 on the connection base 5. Because the hinge shaft of the lower main arm 6.1 is installed relatively far back, it is preferably connected to the hinge shaft of the lower main arm 6.1 to reduce the occupation of the front part of the toilet. A compression reset mechanism is connected between the left and right ring bodies, and the torsion push mechanism and the compression reset mechanism are axially fed along the hinge shaft. When the toilet lid 2 is closed, the hinge shaft of the lower main arm 6.1 rotates, the torsion pushing mechanism pushes the left and right circle bodies together, the compression reset mechanism is compressed, and the left and right circle bodies are stored in the toilet lid 2, so as to achieve the purpose of storing the seat ring 3 without interfering with the work of the sealing ring 4; when the toilet lid 2 is opened, the hinge shaft of the lower main arm 6.1 rotates in the opposite direction, the torsion pushing mechanism does not apply force to the left and right circle bodies, the compression reset mechanism opens, pushes the left and right circle bodies away and resets them, and the left and right circle bodies completely cover the toilet seat, so as to achieve the purpose of not affecting the comfort when sitting on the toilet.

[0037] like Fig. 9 As shown; both ends of the connecting base 5 are provided with lower auxiliary arm hinge holes 5.2, and the connecting base 5 has a transverse cylindrical cavity 5.1.

[0038] like Figure 5 , Figure 6 , Figure 7 The torsion pushing mechanism shown includes a rotating part 7 and a pushing part 11, which are arranged along the axial direction of the rotating shaft of the ring body 3.1, and the rotating part 7 and the pushing part 11 are arranged in the cylindrical cavity 5.1 of the connecting base 5. The rotating part 7 is axially coupled to the lower main arm 6.1 at the hinge shaft on the connecting base 5, and the pushing part 11 is connected to the ring body 3.1. The pushing part 11 is fixed relative to the ring body 3.1, that is, a square columnar plug rod 11.1 extends out of the pushing part 11, and the plug rod 11.1 is inserted into the square hole on the ring body 3.1, and the plug rod 11.1 passes through the other end of the ring body 3.1. The end face of the cylinder wall of the pushing part 11 is a curved surface undulating along the axial direction, the rotating part 7 is connected with the end face, and the pushing part 11 is connected with the rotating part 7 to form a cam pair. When the rotating part 7 rotates, the rotating part 7 slides on the end face of the pushing part 11, and then pushes the pushing part 11 out, and the pushing part 11 pushes the left and right ring bodies 3.1 to come together. When the rotating part 7 rotates in the opposite direction, the compression reset mechanism pushes the left and right ring bodies 3.1 to separate, and the pushing part 11 is reset.

[0039] The compression reset mechanism includes a spring 12, the two ends of which are connected to the left ring body and the right ring body respectively, and the two ends of the spring 12 are respectively sleeved on the external leakage ends of the plug rods 11.1 on both sides. The torsion push mechanism also includes a secondary push part 9, an inner sleeve 8, and a transmission tube 10. The secondary push part 9, the inner sleeve 8, the transmission tube 10, and the rotating part 7 are coaxially arranged. The secondary push part 9, the inner sleeve 8, the rotating part 7, the transmission tube 10, and the push part 11 are sequentially placed in the cylindrical cavity 5.1. That is, the secondary push part 9 is axially and radially fixed, and the rotating part 7 is arranged between the push part 11 and the secondary push part 9, and a connecting rod 7.1 extends from the rotating part 7. In the radial direction, the inner sleeve 8 is arranged between the connecting rod 7.1 and the secondary push part 9, that is, the connecting rod 7.1 slides and extends into the inner sleeve 8, and the inner sleeve 8 is axially connected with the rotating part 7; the inner sleeve 8 passes through the secondary push part 9 and is axially connected with the hinge shaft of the lower main arm 6.1. That is, the hinge shaft of the lower main arm 6 . 1 drives the lining sleeve 8 to rotate, and the lining sleeve 8 transmits the torque to the rotating part 7 .

[0040] like Figure 8 As shown; the inner wall of the transmission tube 10 is provided with a linear groove 10.1 along the axial direction, and the auxiliary driving part 9 and the driving part 11 are inserted from both ends of the transmission tube 10 respectively, and the auxiliary driving part 9 and the driving part 11 have convex strips that match the linear groove 10.1. The auxiliary driving part 9 and the driving part 11 are axially connected through the transmission tube 10, and the auxiliary driving part 9 and the driving part 11 rotate synchronously. The inner wall of the transmission tube 10 is also provided with an arc groove 10.2 along the circumferential direction, and the arc groove 10.2 is located between the auxiliary driving part 9 and the driving part 11. The rotating part 7 is arranged in the transmission tube 10, and the rotating part 7 has a boss 7.2 that matches the arc groove 10.2. Such an arrangement prevents the transmission tube 10 from moving irregularly in the axial direction, so that it can be disengaged from the driving part 11 or the auxiliary driving part 9.

[0041] The end face of the cylinder wall of the auxiliary pushing part 9 is also a curved surface that undulates along the axial direction, and the undulation of the end face corresponds to the end face of the rotating part 7, and the rotating part 7 cooperates with the pushing part 11 and the auxiliary pushing part 9 to form front and rear groups of cam pairs. When the rotating part 7 rotates, the front and rear groups of cam pairs work at the same time, and the pushing part 11 reaches twice the stroke, which can increase the moving distance of the left and right circle bodies, making it easier to be stored in the toilet cover 2 without interfering with the work of the sealing ring 4. When the left and right circle bodies are separated, the center of the circle body 3.1 is on the toilet seat ring, which is more stable when used by users.

[0042] The working process of the torsion push mechanism is as follows: when closing the toilet lid 2, the lower main arm 6.1 hinge shaft rotates the inner lining sleeve 8 connected thereto to transmit the torque to the rotating part 7, and the secondary push part 9 and the push part 11 are connected by the transmission tube 10, so both cannot rotate; when the rotating part 7 rotates, due to the cam pair combined with the secondary push part 9, the rotating part 7 body moves and pushes the push part 11, and because the rotating part 7 and the push part 11 also form a cam pair, the push part 11 is also pushed out relative to the rotating part 7 at the same time; during the movement of the rotating part 7, because it is slidably connected with the inner lining sleeve 8, the torque is continuous during the movement. That is, when closing the toilet lid 2, the left and right ring bodies are pushed together by the push part 11, and the left and right ring bodies are gathered and stored in the toilet lid 2, without interfering with the work of the sealing ring 4, ensuring the overall sealing of the inner cavity of the toilet;

[0043] When the toilet lid 2 is opened, the rotating part 7, the auxiliary pushing part 9, the pushing part 11 and the inner lining sleeve 8 all move in the opposite direction, and the compression reset mechanism pushes the left and right ring bodies away, and the left and right ring bodies are reset.

[0044] The left and right ring bodies are relatively fixed in the circumferential direction. When the seat ring 3 needs to be lifted, force can be applied to any ring body 3.1 to lift the seat ring 3 as a whole. Fig.10 , Fig.11 Also includes a seat ring sleeve 13, the left and right ring bodies are connected by the seat ring sleeve 13, the seat ring sleeve 13 has a channel 13.2 respectively matched with the left and right ring bodies, the seat ring sleeve 13 has a notch 13.1 for accommodating the left and right ring bodies, and the bottom of the left and right ring bodies has a notch for accommodating the bottom plate of the seat ring sleeve.

[0045] When the seat ring 3 is lifted, the rotating part 7 is fixed, the pushing part 11 rotates with the ring body 3.1, and the auxiliary pushing part 9 rotates synchronously with the pushing part 11. The two ring bodies 3.1 are close to each other during the flipping process. After the seat ring 3 is lifted, it is stored in the toilet cover 2.

[0046] like Fig.12 , Fig.13 As shown; a locking pin 14 is arranged on the connecting base 5, and the locking pin 14 is arranged horizontally. The locking pin 14 includes a box body 14.1, and a compression spring 14.2 and a ball pin 14.3 are arranged in the box body 14.1. The compression spring 14.2 is arranged between the ball pin 14.3 and the box body 14.1, and the ball head of the ball pin 14.3 extends out of the box body 14.1. A locking plate 15 is arranged on the lower main arm 6.1, and the lower edge of the lower main arm 6.1 expands outward to form the locking plate 15, and the locking plate 15 has a circular groove that matches the ball head of the ball pin 14.3. When the toilet lid 2 is closed, the ball head of the ball pin 14.3 is embedded in the circular groove of the locking plate 15. During the flushing process, the locking pin 14 prevents the toilet lid 2 from bouncing up; when the toilet lid is opened, the lower main arm 6.1 rotates, the ball head of the ball pin 14.3 escapes from the circular groove, and the compression spring 14.2 is compressed.

[0047] The present invention also provides a toilet, including the above-mentioned sealed toilet cover, which is installed on the toilet through the connecting base 5. After the toilet cover 2 is closed, the sealing ring 4 fits with the toilet seat, and a sealed space is formed in the toilet cavity. When the toilet is flushed, the pressure difference between the pressure in the toilet cavity and the atmospheric pressure increases, thereby achieving the purpose of saving water and improving the flushing ability; a one-way air valve 2.2 is installed at the air inlet 2 on the toilet cover 2. After the excrement is flushed away, the indoor gas flows into the toilet cavity through the one-way air valve 2.2, and the air pressure in the toilet cavity is balanced with that in the room, and the toilet cover 2 can be opened normally. The one-way air valve 2.2 only allows the indoor gas to flow into the toilet cavity, and does not allow the gas in the toilet cavity to flow out. When the toilet is flushed, it is ensured that the pressure in the toilet cavity is not released, and bacteria will not burst and flow into the room; when the toilet is vacant, the bacteria in the toilet cavity will not flow into the room.

[0048] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
