Description

Technical Field

[0001] The invention belongs to the technical field of intelligent toilets and relates to a cover closing and flushing device for an intelligent toilet. Background Art

[0002] With the improvement of people's living standards, toilets have gradually become indispensable sanitary appliances in people's lives, and the application of toilets has been very common. When using the existing toilet, flushing and covering the toilet cover are operated in two steps, which is troublesome to operate.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, a new type of self-flushing device for a toilet with a closed cover is disclosed in Chinese patent literature [Patent No.: 200720038661.9; Authorization Announcement No.: CN201065568Y], which includes a flushing device, a fixed bracket, and a pull rope. One end of the pull rope is fixedly connected to the upper cover of the toilet, and the other end of the pull rope is connected to the flushing device. The downward pressure end of the flushing device is connected to the flushing button. The flushing device is fixed above the toilet body through a fixed bracket, and the fixed bracket is fixed to the ground on one side of the toilet body.

[0004] The toilet of this structure realizes flushing by closing the lid, which improves the convenience of operation. However, the flushing device and the pull rope of the toilet of this structure need to be moved during the process of closing the lid. Because the flushing device and the pull rope are both located outside the toilet, the flushing device and the pull rope are easily disturbed by the outside during operation, which leads to failure of flushing when closing the lid and poor stability. Moreover, the middle part of the pull rope is switched by a pulley, and the pull rope may fall off the pulley during movement, which leads to failure of flushing when closing the lid and poor stability. Finally, the flushing device of the toilet of this structure has many parts and components, many mechanical transmission links in the middle, and a complex structure. When flushing when closing the lid, deviations are likely to occur during the transmission process, and there is a problem of jamming, which leads to failure of flushing when closing the lid and poor stability. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a cover-closing and flushing device for an intelligent toilet, the technical problem to be solved is how to improve the stability of the cover-closing and flushing of the toilet.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a closed-lid flushing device for an intelligent toilet, the toilet comprising a seat cover and an upper cover, the seat cover and the upper cover being hinged via a rotating shaft, characterized in that the closed-lid flushing device comprises a rotating portion protruding from the rotating shaft and an installation box fixed to the inner side wall of the upper cover and having an installation cavity inside, the installation box being provided with a first micro switch connected to the intelligent toilet controller, a rotatable switching rod and a reset member capable of resetting the switching rod, the rotation of the upper cover can drive the rotating portion to rotate via the rotating shaft, the rotating portion can drive the switching rod to rotate so that the first micro switch is normally open or normally closed.

[0007] This closed lid flushing device is used in conjunction with an intelligent toilet. The intelligent toilet controller controls the water inlet and flushing operations of the toilet. This is a prior art and will not be described in detail. After the seat cover is flipped up 90° to position, the rotating part does not contact the switching rod, and the first micro switch is in a normally open state (taking normally open as an example). When flushing, turn the seat cover. When the seat cover rotates a certain angle, the rotating part contacts the switching rod. When the seat cover continues to rotate, the rotating part drives the switching rod to rotate, so that the first micro switch is normally closed. The seat cover continues to rotate until it is horizontal. The rotating part will pass over the switching rod and no longer contact the switching rod. The switching rod is reset, and the first micro switch is in a normally open state. The intelligent toilet controller receives the above signal to perform flushing and water inlet operations. When the seat cover is flipped up again to open the seat cover to a 90° position, the rotating part will pass over the switching rod during this process, and the reset member can reset the switching rod for the next closed lid flushing. The rotating part in the present cover flushing device is arranged on the rotating shaft, and the installation box is located on the inner side of the upper cover, that is, the present cover flushing device is located as a whole inside the intelligent toilet, will not be disturbed by the outside world, and has good stability; by arranging the rotating part on the rotating shaft and fixing the installation box at the rotating part, the installation space occupied is small, the position is close, and it is less susceptible to interference, and the signal is transmitted by the first micro switch, which can improve the stability of the present cover flushing device.

[0008] In the above-mentioned intelligent toilet lid flushing device, the reset member is a second micro switch, the second micro switch has the same structure as the first micro switch, the first micro switch and the second micro switch are symmetrically arranged on both sides of the switch rod, and the first micro switch and the second micro switch both include elastic touch plates, and the two touch plates can respectively abut on both sides of the inner end of the switch rod. The second micro switch is used as a reset member, and the second micro switch has the same structure as the first micro switch, that is, the elastic force of the touch plates of the first micro switch and the second micro switch is basically the same, and the first micro switch and the second micro switch are symmetrically arranged. When the switch rod rotates to the set position, the first micro switch and the reset member exert the same force on the switch rod, ensuring that the switch rod does not deflect after being located at the set position, thereby improving the stability of the lid flushing device. The touch plate of the first micro switch also has a reset function, and the touch plate of the first micro switch cooperates with the reset member to reset the switch rod.

[0009] In the above-mentioned intelligent toilet lid flushing device, the first micro switch and the second micro switch both further include a housing and a button, the button being arranged on the housing, one end of the touch sheet being fixedly connected to the housing, the other end of the touch sheet being able to contact the inner end of the switch rod, and the switch rod being able to drive the touch sheet to contact the button. The touch sheet is elastic and plays a dual role of resetting and contacting the button. When the touch sheet contacts the button, it can push the button to move, and when the touch sheet leaves the button, the button can be reset, which can reduce the number of parts of the lid flushing device and the number of transfer steps, thereby improving stability.

[0010] In the above-mentioned intelligent toilet lid flushing device, two pairs of positioning plates are fixed in the installation cavity, and the two opposite inner side walls of each pair of positioning plates have protruding positioning parts, and the shell has a recessed positioning groove. The two shells are respectively embedded in the corresponding pair of positioning plates and the positioning parts are embedded in the positioning grooves so that the first micro switch and the second micro switch are fixed in the installation box. The positioning plates, positioning parts and positioning grooves are all used to improve the installation stability of the first micro switch and the second micro switch, so that the normally closed and normally opened state of the first micro switch is timely and reliable, and the reset of the first micro switch and the second micro switch is timely and reliable, thereby improving the stability of the lid flushing device.

[0011] As another example, in the above-mentioned intelligent toilet lid closing and flushing device, the reset member is a cylindrical spring, one end of which acts on the installation box, and the other end of which acts on the inner end of the switch rod. The switch rod is reset by the cylindrical spring, and the structure is simple.

[0012] In the above-mentioned intelligent toilet lid flushing device, the top of the installation box has a notch, the notch is connected to the installation cavity, the installation cavity has a rotating column, the rotating column is located at the notch, the middle of the switch rod has a rotating hole, the rotating column passes through the rotating hole so that the switch rod can rotate around the rotating column, and the outer end of the switch rod is located outside the notch. The notch is set so that the outer end of the switch rod can extend out of the notch, the rotating hole and the rotating column are located at the notch, that is, the rotating part of the switch rod is located in the installation cavity, so that the rotation of the switch rod is not easily disturbed by the outside world, and the stability of the present lid flushing device is improved.

[0013] In the above-mentioned intelligent toilet lid flushing device, the middle of the switch lever is convex toward both sides to form a reinforcement part, and the rotation hole is located in the middle of the two reinforcement parts. The reinforcement part improves the strength of the middle of the switch lever and the strength of the switch lever rotation part; and the reinforcement part is provided so that the rotation hole has a sufficient opening position, so that the two ends of the switch lever can be made relatively smaller, so that the switch lever is not easily stuck during the rotation process, and the stability is improved.

[0014] In the above-mentioned intelligent toilet lid closing and flushing device, both sides of the outer end of the switch rod have inclined guide surfaces, the end surface of the outer end of the switch rod is an arc surface, the two guide surfaces are connected by the arc surface, and the rotating part can contact the guide surface. The setting of the guide surface and the arc surface allows the switch rod and the rotating part to contact smoothly, and the rotating part can pass over the switch rod smoothly, so that the lid closing and flushing is smooth, and the stability of the lid closing and flushing device is improved.

[0015] In the above-mentioned intelligent toilet lid flushing device, the inner end of the switch rod is protruded outward to form a switch portion, and the outer wall of the switch portion is arc-shaped. This structure allows the inner end of the switch rod to contact the trigger piece smoothly, so that the lid flushing is smooth, and the stability of the lid flushing device is improved.

[0016] In the above-mentioned intelligent toilet lid flushing device, the installation box has a protruding lug on the top, the inner side wall of the upper cover has a protruding mounting post, the bottom of the mounting post has a fixing groove, the lug is embedded in the fixing groove in its entirety or in part, and the outer side wall of the lug fits the inner side wall of the fixing groove, and the lug and the mounting post are fixedly connected by fasteners. The lug is protruding, and the mounting post is also protruding. This structure allows the installation box to have sufficient installation space, and the installation box can be installed against the inner side wall of the upper cover. Moreover, this matching mode of the lug and the fixing groove can improve the firmness and stability of the installation of the installation box, thereby improving the stability of the present lid flushing device.

[0017] Compared with the prior art, the intelligent toilet lid closing and flushing device provided by the present invention has the following advantages:

[0018] 1. The cover-closing and flushing device of the intelligent toilet is integrally arranged inside the toilet, has no contact with the outside world, and is not easily disturbed by the outside world, thereby improving the stability of the cover-closing and flushing device.

[0019] 2. The cover-closing and flushing device of the intelligent toilet transmits signals through a micro switch, and resets the switching rod through the micro switch. It has a simple structure, stable signal transmission, and stable reset, thereby improving the stability of the cover-closing and flushing device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Embodiment 1

[0030] like Figure 1 , Figure 2As shown, the toilet comprises a seat cover 1, an upper cover 2 and a lid-closing flushing device, the seat cover 1 and the upper cover 2 are hinged via a rotating shaft 3, the rotating shaft 3 is fixedly connected to the seat cover 1, and the rotation of the upper cover 2 can drive the rotating shaft 3 to rotate. The lid-closing flushing device comprises a rotating part 4, a mounting box 5, a first micro switch 6, a switching rod 7 and a reset member 8.

[0031] like Figure 3 As shown, the installation box 5 has an installation cavity 51 inside, and the first micro switch 6, the switching rod 7 and most of the reset member 8 are located in the installation cavity 51. The top of the installation box 5 has a notch 54, and the notch 54 is connected to the installation cavity 51. The installation cavity 51 has a rotating column 55, and the rotating column 55 is located at the notch 54. The middle of the switching rod 7 is convex to both sides to form a reinforcement part 72. The middle of the two reinforcement parts 72 has a rotating hole 71. The rotating column 55 passes through the rotating hole 71 so that the switching rod 7 can rotate around the rotating column 55. The outer end of the switching rod 7 is located outside the notch 54. Both sides of the outer end of the switching rod 7 have inclined guide surfaces 73. The end surface of the outer end of the switching rod 7 is an arc surface. The two guide surfaces 73 are connected through the arc surface, and the rotating part 4 can contact the guide surface 73. The inner end of the switching rod 7 is convex outward to form a switching part 74. The outer side wall of the switching part 74 is arc-shaped, and the switching part 74 can contact the trigger sheet 9.

[0032] The first micro switch 6 is connected to the controller of the intelligent toilet, and the reset member 8 is the second micro switch. The second micro switch has the same structure as the first micro switch 6. The first micro switch 6 and the second micro switch are symmetrically arranged on both sides of the switch rod 7. The first micro switch 6 and the second micro switch both include a housing 10, a button 11 and an elastic touch sheet 9. The button 11 is arranged on the housing 10. One end of the touch sheet 9 is fixedly connected to the housing 10, and the other end of the touch sheet 9 can contact the inner end of the switch rod 7. Two pairs of positioning plates 52 are fixed in the installation cavity 51. The two opposite inner side walls of each pair of positioning plates 52 have protruding positioning parts 53. The housing 10 has a recessed positioning groove 12. The two housings 10 are respectively embedded in the corresponding pair of positioning plates 52 and the positioning parts 53 are embedded in the positioning groove 12 so that the first micro switch 6 and the second micro switch are fixed in the installation box 5.

[0033] like Figure 4 As shown, the mounting box 5 has a protruding lug 56, the inner side wall of the upper cover 2 has a protruding mounting post 13, and the bottom of the mounting post 13 has a fixing groove 14. In this embodiment, the lug 56 is partially embedded in the fixing groove 14. In actual production, the lug 56 can be fully embedded in the fixing groove 14. The outer side wall of the lug 56 fits the inner side wall of the fixing groove 14, and the lug 56 and the mounting post 13 are fixedly connected by fasteners such as bolts or screws. The rotating part 4 is protruding on the rotating shaft 3, and the rotating part 4 moves with the rotating shaft 3.

[0034] like Figure 5 As shown, after the seat cover 1 is flipped up 90° and positioned, the rotating part 4 is not in contact with the switching rod 7. In this embodiment, the first micro switch 6 is in a normally open state. In actual production, the first micro switch 6 can be in a normally closed state. The switching rod 7 is located in the middle initial position under the joint action of the first micro switch 6 and the triggering piece 9 of the second micro switch. Figure 6 As shown, when flushing with the lid closed, when the seat cover 1 rotates to an angle of 45°, the rotating part 4 begins to contact the outer end of the switching rod 7. The seat cover 1 continues to rotate, and the rotating part 4 rotates to drive the switching rod 7 to rotate, so that the switching rod 7 overcomes the elastic force of the touch sheet 9 of the first micro switch 6 to rotate the touch sheet 9, and the touch sheet 9 contacts the button 11 of the first micro switch 6 to close the button 11. When the seat cover 1 rotates to an angle exceeding 60°, the rotating part 4 will pass over the switching rod 7 and no longer contact the switching rod 7. The controller of the smart toilet receives the above signal to perform flushing and water supply operations. Figure 7 As shown, when the seat cover 1 is closed, the rotating part 4 is no longer in contact with the switching rod 7. The switching rod 7 is pushed by the first micro switch 6 contact piece 9 to cooperate with the second micro switch contact piece 9 to reset, and the first micro switch 6 is in a normally open state. When people flip the seat cover 1 to open the seat cover 1, the rotating part 4 rotates in the opposite direction, and the rotating part 4 causes the switching rod 7 to overcome the second micro switch contact piece 9 to rotate. At this time, the first micro switch 6 is still in a normally open state, and the rotating part 4 passes over the switching rod 7. The switching rod 7 is pushed by the second micro switch contact piece 9 to cooperate with the first micro switch 6 contact piece 9 to reset, so that it can be used for flushing next time the cover is closed.
