Description

Technical Field

[0001] The invention relates to the field of intelligent toilets. Background Art

[0002] With the development of society, people have higher and higher requirements for the cleanliness and comfort of toilets, so squat toilets are gradually being replaced by toilets. Traditional toilets usually consist of a water tank, a toilet seat and a toilet base, in which the toilet seat is directly hinged to the toilet base. When using the toilet, the toilet seat is flipped down, and when you are done, you can flip it up again.

[0003] Since the toilet seat is in direct contact with the human body, it needs to be cleaned frequently. However, with the increase in labor costs, the cost of directly hiring cleaners to clean the toilet is high. Therefore, automated toilets have become an important research field. Automated toilets are generally designed with automatic toilet cleaning equipment to clean the toilet. However, the existing automatic toilet cleaning equipment usually cleans the toilet base, while the toilet seat still needs to be cleaned manually. The main reason for this problem is that the toilet seat is usually directly hinged to the toilet base, and the toilet seat can only be flipped in two directions, up and down. When cleaning the toilet base, the toilet seat needs to be flipped upwards to clean the inside of the toilet base. Therefore, it is difficult for the automatic toilet cleaning equipment to clean the toilet seat and the toilet base at the same time. The toilet seat needs to be cleaned separately from the toilet base. Moreover, the hinge position between the toilet seat and the toilet base is relatively narrow, and it is difficult to clean it thoroughly even if it is scrubbed manually.

[0004] Furthermore, the cleaning of the inside of the toilet base only requires brushing the inside with a brush and then flushing it directly, and it does not need to be kept dry. However, the toilet seat needs to be in direct contact with human skin and must be kept dry, otherwise it will affect the comfort and cause bacteria to grow on the toilet seat. Considering that the toilet base and toilet seat need to be cleaned separately when using the above-mentioned automatic toilet cleaning device, in actual applications, there is a situation where the toilet base has been cleaned but the toilet seat has not been cleaned, which will cause the toilet to be unable to be used normally.

[0005] Especially in public toilets, due to the high frequency of use, the toilet seat needs to be cleaned frequently. However, the toilet seat of the prior art cannot be cleaned immediately after a user finishes using the toilet. Summary of the invention

[0006] The technical problem to be solved by the present invention is that the existing toilet seat is directly hinged to the toilet base, and the toilet seat is difficult to be cleaned well. Moreover, when using the automatic toilet cleaning device, the toilet seat and the toilet base are cleaned separately, and there is a problem that the toilet base has been cleaned but the toilet seat has not been cleaned or dried, so the toilet cannot be used.

[0007] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0008] The present invention provides an interchangeable double toilet seat assembly, comprising at least: a first toilet seat, the first toilet seat being provided with a use position and a cleaning and disinfection position, the first toilet seat being provided with a first drive device and being configured to drive the first toilet seat to switch between the use position and the cleaning and disinfection position by means of the first drive device; a second toilet seat, the second toilet seat being provided with a use position and a cleaning and disinfection position, the second toilet seat being provided with a second drive device and being configured to drive the second toilet seat to switch between the use position and the cleaning and disinfection position by means of the second drive device, the use position of the second toilet seat being coincident with the use position of the first toilet seat.

[0009] The advantage of the above scheme is that the positions of the first toilet seat and the second toilet seat can be switched freely. When one of them is in the cleaning and disinfection position, the other can be in the use position, ensuring that there is always one toilet seat that can be used normally. Moreover, in a public toilet, when a toilet user finishes using the toilet, the used toilet seat can be immediately switched to the cleaning and disinfection position, and the other toilet seat that has just been cleaned and disinfected can be immediately switched to the use position, so that the next toilet user can use a clean toilet seat, thereby improving the overall cleanliness of the public toilet. The use positions of the first toilet seat and the second toilet seat overlap, and when using different toilet seats, the user's sitting position height is the same, which will not cause discomfort in the sitting feeling.

[0010] Preferably, the cleaning and disinfection position of the second toilet ring coincides with the cleaning and disinfection position of the first toilet ring, and both the first toilet ring and the second toilet ring achieve switching between the use position and the cleaning and disinfection position by rotating in a horizontal plane, and the second toilet ring and the first toilet ring rotate coaxially.

[0011] The advantages of the above scheme are that the first toilet seat rotates coaxially with the second toilet seat, and the cleaning and disinfection positions of the first toilet seat and the second toilet seat also overlap, which is helpful for the position design of the drive component and the position design of the disinfection component during specific implementation, and the coaxial rotation helps to save space. In addition, the drive device that outputs rotational motion has a large number of practical applications, and the component design is more convenient.

[0012] Preferably, it also includes a base, the base is provided with a positioning cylinder extending in the vertical direction, the positioning cylinder is provided with a mounting through hole extending in the vertical direction, and the mounting through hole is coaxial with the positioning cylinder; the rotation direction of the first toilet ring when switching between the use position and the cleaning and disinfection position is the same as that of the second toilet ring, and the rotation angle is less than 180°; the first toilet ring is hinged with a first connecting plate, and the first toilet ring can be flipped in the vertical direction relative to the first connecting plate; the first connecting plate includes a first connecting portion which is sleeved on the positioning cylinder and driven by the first driving device; the second toilet ring is hinged with a second connecting plate, and the second toilet ring can be flipped relative to the The second connecting plate flips in the vertical direction; the second connecting plate includes a second connecting portion, and the second connecting portion is fixedly connected with a lifting device for lifting the second toilet seat, and the lifting device is rotatably connected in the mounting through hole and driven to rotate by the second driving device, and the lifting device drives the second connecting plate to rotate when it rotates; under the drive of the lifting device, the second connecting plate can be moved in the vertical direction to at least an upper limit position and a lower limit position, and when the second connecting plate is at the upper limit position, the lower end surface of the second connecting plate is higher than the upper end surface of the first connecting plate, and when the second connecting plate is at the lower limit position, the second connecting plate is flush with the height of the first connecting plate.

[0013] The advantage of the above solution is that, since the first connecting plate and the second connecting plate are respectively provided, the first mounting end and the second mounting end can be connected to the first toilet ring and the second toilet ring respectively, and when one toilet ring is cleaned, the other toilet ring can be used normally. The first connecting plate and the second connecting plate are also respectively connected to the first driving device and the second driving device, so that the first connecting plate and the second connecting plate can be rotated to a position away from the toilet base below, and the toilet ring will not be disturbed by the toilet base during the cleaning process, making the cleaning of the toilet ring more convenient.

[0014] In actual application, in order to save space, the trajectories of the first toilet ring and the second toilet ring rotating in the horizontal plane overlap, so there is inevitably motion interference between the two. In order to ensure that the two toilet rings will not be interfered with by each other during their respective rotations, the second connecting plate is connected to a lifting device. Under the action of the lifting device, the second connecting plate can move up and down. When it moves to the lower limit position, the second connecting plate is flush with the height of the first connecting plate, and the toilet rings can be located above the toilet base, so that the toilet ring can be used normally; when it moves to the upper limit position, the second connecting plate is located above the first connecting plate as a whole, and the second connecting plate will not hit the first connecting plate during rotation. Combined with the action of the first drive device and the second drive device, the free rotation of the first connecting plate and the second connecting plate and the position switching between the two can be realized, realizing the function of one wash and one use.

[0015] Preferably, a receiving groove capable of receiving the first connecting plate is provided at a position of the second connecting plate close to the first connecting plate.

[0016] Preferably, the lifting device at least includes: a rotating seat, which is rotatably connected to the mounting through hole and driven by the second driving device, and a mounting cavity is provided in the rotating seat; a lifting driving device, which is fixedly arranged in the mounting cavity, and the output end of the lifting driving device is connected to a connecting block, and the lifting driving device drives the connecting block to move in a vertical direction; a lifting platform, which is fixedly connected to the connecting block, and the lifting platform is fixedly connected to the second connecting part.

[0017] The advantage of the above scheme is that the second driving device can drive the rotating seat, the lifting driving device and the lifting platform to rotate at the same time, and finally drive the second connecting plate to drive the lifting device to play the role of vertical displacement drive and rotation transmission at the same time. The force transmitted from the connecting block to the lifting platform is more evenly distributed, and the overall structure of the lifting driving device is simple. The lifting driving device can be set to be electrically driven by a program, which helps to improve the degree of automation.

[0018] Furthermore, the lifting platform is movably connected in the installation cavity, the inner wall of the installation cavity is provided with a limiting guide protrusion extending in the vertical direction, and the outer wall surface of the lifting platform is provided with a limiting guide groove adapted to the limiting guide protrusion.

[0019] The advantage of the above scheme is that after the limit guide protrusion is connected with the limit guide groove, on the one hand, it can provide a guiding function for the movement of the lifting platform in the vertical direction, and on the other hand, it can also provide a limit function and a force point for the lifting platform in the rotation direction, making it convenient for the rotating seat to drive the lifting platform to rotate.

[0020] Preferably, the second driving device at least includes: a rotating disk, which is fixedly connected to the rotating seat, and the rotating axis of the rotating disk coincides with the rotating axis of the rotating seat; a disk connecting portion is provided on the outer circumference of the rotating disk; a transverse linear driving device, one end of which is provided with a hinged end hinged to the base, and the other end of the transverse linear driving device is provided with a driving end, the driving end is connected to a connecting rod, and the connecting rod moves along the axial direction of the driving end when driven by the driving end, and the connecting rod is provided with a plug column, and the plug column is rotatably connected to the disk connecting portion.

[0021] The advantage of the above scheme is that one end of the transverse linear drive device is hinged to the base. When the drive end outputs a driving force in a linear direction, since the rotating disc can only rotate in a circular direction, the reaction force generated by the rotating disc will drive the entire transverse linear drive device to swing, thereby conveniently converting the linear motion into rotational motion. Moreover, the transverse linear drive device has a simple structure, which helps to control the overall volume, and the output power can also meet the demand. It should be noted that the rotation range of the rotating disc should avoid the dead point position, that is, the force of the drive end is just along the radial direction of the rotating disc to prevent the rotating disc from failing to rotate normally after moving to the dead point position.

[0022] Preferably, a limiting ring protruding outward is provided on the outer surface of the rotating seat, and the rotating disk is fixedly connected to the lower end surface of the rotating seat; the diameter of the mounting through hole is smaller than the diameters of the limiting ring and the rotating disk, and the part of the rotating seat located between the rotating disk and the limiting ring is provided with a mounting portion whose length and diameter are adapted to the mounting through hole.

[0023] The advantage of the above solution is that the limiting ring and the rotating disc are respectively against the two side end surfaces of the base, which play a limiting function on the rotating seat and prevent the rotating seat from moving or vibrating in the vertical direction.

[0024] Preferably, the first connecting part is provided with a first connecting column extending along the rotation axis direction of the first connecting part; the first driving device at least includes a transverse linear driving device, one end of which is provided with a hinged end hinged to the base, and the other end of the transverse linear driving device is provided with a driving end, and the driving end is connected to a connecting rod, and the connecting rod moves along the axial direction of the driving end under the drive of the driving end, and the connecting rod is provided with an insert column, and the insert column is rotatably connected in the first connecting column.

[0025] Furthermore, the base is provided with an arc-shaped positioning groove, the center of which is located on the rotation axis of the first connecting part; the first driving device and the first connecting part are respectively located on the upper and lower sides of the base, and the first connecting column is arranged through the positioning groove.

[0026] In summary, the above solution has the following advantages:

[0027] 1. The first toilet seat and the second toilet seat can be switched automatically to ensure that one toilet seat can always be used;

[0028] 2. The overall structure is simple, which helps to control production costs;

[0029] 3. Each drive device can be controlled through electrical connection, which helps to achieve overall automation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] A preferred implementation of this scheme is as follows Figures 1 to 14 See Figure 1, the embodiment at least includes a base 3, a first connecting plate 11 and a second connecting plate 21. The first mounting end 110 of the first connecting plate 11 is hinged with a first toilet ring 10, and the first toilet ring 10 can be flipped in the vertical direction. The other end of the first connecting plate 11 is provided with a first connecting portion 12, and the first connecting portion 12 is rotatably connected to the base 3, and the first connecting plate 11 can rotate in a horizontal plane. Similarly, the second mounting end 210 of the second connecting plate 21 is hinged with a second toilet ring 20, and the second connecting plate 21 can also rotate automatically, and the rotation axis of the second connecting portion 23 coincides with the rotation axis of the first connecting portion 12. The first toilet ring 10 and the second toilet ring 20 realize the switching between the use position and the cleaning and disinfection position through rotational movement. Figure 1 In the embodiment, the first toilet seat 10 is located in the use position and the second toilet seat 20 is located in the disinfection position, that is, in this embodiment, the use position and the cleaning and disinfection position differ by 90°. Moreover, the use position and the cleaning and disinfection position of the first toilet seat 10 and the second toilet seat 20 coincide with each other, and the two switch positions by means of rotational motion, which helps to save space. Furthermore, an external partition can be provided to separate the use position and the cleaning and disinfection position, and a receiving groove can be provided on the partition to accommodate the first toilet seat 10 and the second toilet seat 20 respectively, so as to avoid one toilet seat affecting the use of the other toilet seat during cleaning.

[0049] In order to realize that both the first connecting plate 11 and the second connecting plate 21 can rotate automatically, the first connecting plate 11 is connected to a first driving device, and the second connecting portion 22 is connected to a lifting device 5, which can drive the second connecting plate 21 to move up and down in the vertical direction. The lifting device 5 is connected to a second driving device, and the second driving device drives the lifting device 5 and the second connecting plate 21 to rotate in the plane. The second connecting plate 21 includes at least an upper limit position and a lower limit position in the vertical direction, referring to Fig.14 When the second connecting plate 21 is at the upper limit position, the lower end surface of the second connecting plate 21 is higher than the upper end surface of the first connecting plate 11, and the second connecting plate 21 is higher than the first connecting plate 11 as a whole, and the second connecting plate 21 will not touch the first connecting plate 11 during the rotation process; Figure 1 When the second connecting plate 21 is at the lower limit position, the second connecting plate 21 is flush with the first connecting plate 11. With the support of the above technical solution, the positions of the first toilet ring 10 and the second toilet ring 20 can be switched to ensure that one can be used normally while the other is being cleaned.

[0050] In this embodiment, in order to control the overall volume as much as possible, the first connecting plate 11 and the second connecting plate 21 are rotatable at an angle of 90° in the horizontal plane, and the overall volume is small, so the first connecting plate 11 and the second connecting plate 21 will interfere with each other, and the second connecting plate 21 will collide with the first connecting plate 11 when it descends to the lower limit position. Figure 7 As shown, a receiving groove 200 is provided on the lower side of the second connecting plate 21 near the first connecting plate 11. When the second connecting plate 21 drops to the lower limit position, the receiving groove 200 can accommodate the part of the first connecting plate 11 near the second connecting plate 21 therein, thereby preventing mutual obstruction between the first connecting plate 11 and the second connecting plate 21.

[0051] refer to Figure 6 In a preferred embodiment of the base 3 , a positioning cylinder 31 is provided on the surface of the base 3 , and the first connecting portion 12 is sleeved outside the positioning cylinder 31 . The first connecting portion 12 can rotate around the positioning cylinder 31 .

[0052] refer to Figure 5 The first driving device includes a transverse linear driving device 13, one end of which is provided with a hinged end 132, and a first hinged portion 14 is provided on the base 3, and the first hinged portion 14 is hinged to the hinged end 132. The other end of the transverse linear driving device 13 includes a driving end 130 that can move along a horizontal straight line direction, and the driving end 130 is connected to a connecting rod 131, and a plug 133 is provided on the connecting rod 131. Fig.13 The lower side of the connecting plate 11 is provided with a first connecting column 16, and the plug column 133 is inserted into the first connecting column 16. The force output by the driving end 130 is transmitted to the first connecting column 16 through the plug column 133. The above-mentioned lateral driving device 13 can output linear motion, and can be designed in various forms such as electric push rods, electric screw rods or hydraulic rods during specific implementation.

[0053] Reference Figures 2 to 5 The horizontal linear drive device 13 is arranged on the lower side of the base 3, the first connecting plate 11 is located on the upper side of the base 3, and a positioning groove 15 is provided on the base 3. The first connecting column 16 passes through the positioning groove 15 and is rotatably connected with the plug column 133. The shape of the positioning groove 15 is designed with reference to the motion trajectory of the connecting column 16. In the embodiment, the positioning groove 15 is an arc groove, and the positioning groove 15 is coaxial with the above-mentioned positioning cylinder 31. The positioning groove 15 provides the first connecting plate 11 with a rotation limit and a function of limiting the rotation angle of the first connecting plate 11.

[0054] The principle by which the transverse linear drive device 13 drives the first connecting plate 11 to rotate is as follows: the first connecting portion 12 is restricted by the base 3 and can only perform rotational motion. After the force output by the driving end 130 is transmitted to the first connecting column 16, the base 3 generates a reaction force toward the connecting column 16. This reaction force drives the transverse linear drive device 13 to swing around the hinge position with the base 3. The combined force direction of the reaction force generated at the base 3 and the force output by the driving end 130 eventually points to the circumferential tangent direction of the positioning groove 15, driving the first connecting plate 11 to rotate. As mentioned above, the setting of the transverse linear drive device 13 should avoid the problem of dead points, and the positions on both sides of the first hinged portion 14 close to the transverse linear drive device 13 need to leave space for the transverse linear drive device 13 to swing. For details, please refer to Figure 3 As shown, first avoidance bevels 140 are provided on both sides of the first hinged portion 14 to prevent the transverse linear drive device 13 from colliding with the first hinged portion 14 when swinging around the first hinged portion 14 .

[0055] The basic structure of the second driving device in the preferred embodiment is the same as that of the first driving device, and the transmission principle is also basically the same. The specific setting method is referred to above. Of course, the first driving device and the second driving device can also be set as devices similar to the form of rotating motors, as long as they can output power to drive the first connecting plate 11 and the second connecting plate 21 to rotate.

[0056] Structural reference of lifting device embodiment Figures 7 to 12 , the lifting device 5 in the embodiment at least includes a lifting platform 51, a lifting drive device 52 and a rotating seat 53. The rotating seat 53 is fixedly connected with a rotating disk 41, and a disk connecting portion 410 is provided on the outer circumferential surface of the rotating disk 41, and the disk connecting portion 410 is connected to the above-mentioned second drive device, and the second drive device drives the rotating disk 41 to rotate. Of course, it is also feasible that the rotating seat 53 is directly connected to the second drive device. An installation cavity 533 is provided in the rotating seat 53, and the lifting drive device 52 is fixedly arranged in the installation cavity 533, and the lifting drive device 52 is fixedly connected to the lifting platform 51, and the lifting platform 51 can move in the vertical direction under the action of the lifting drive device 52. The lifting platform 51 is fixedly connected to the second connecting plate 21, and the lifting platform 51 drives the second connecting plate 21 to move up and down. At the same time, the rotating seat 53 drives the lifting drive device 52 and the lifting platform 51 to rotate together during the rotation process, thereby driving the second connecting plate 21 to rotate.

[0057] In a preferred embodiment of the lifting drive device 52, the output end of the lifting drive device 52 is connected to a connecting block 522, and the lifting drive device 52 drives the connecting block 522 to move in the vertical direction. A connecting groove 512 adapted to the connecting block 522 is provided on the lifting platform 51, and the connecting block 522 is fixedly arranged in the connecting groove 512. The matching connection between the connecting block 522 and the connecting groove 512 can increase the lifting stability of the lifting platform 51. Similar to the horizontal linear driving device 13, the lifting drive device 52 is preferably designed as a vertical push rod 521, and the vertical push rod 521 moves the output end in a linear direction by pressure drive or electric drive. Of course, the lifting drive device 52 can also be set in the form of an electric screw rod, which has been widely used, and the corresponding connection structure only needs to make adaptive changes. In the embodiment where the lifting drive device 52 is designed as an electric screw rod, the connecting block 522 is threadedly connected to the screw rod, and the screw rod device converts the rotational motion of the screw rod into the linear motion of the connecting block 522. The electric push rods, electric screw rods or hydraulic rods mentioned in the above solutions are all existing technologies, and their specific working principles are not described in detail here.

[0058] Furthermore, a limiting guide protrusion 534 extending in the vertical direction is provided on the inner wall of the installation cavity 533, and a limiting guide groove 511 adapted to the limiting guide protrusion 534 is provided on the outer wall of the lifting platform 51. After the limiting guide protrusion 534 is connected to the limiting guide groove 511, on the one hand, it can provide a guiding function for the lifting platform 51 during the movement of the lifting platform 51 in the vertical direction, ensuring that the lifting platform 51 always moves in the vertical direction, and on the other hand, it can provide a limiting function for the lifting platform 51 to prevent the lifting platform 51 from rotating. When the rotating seat 53 rotates, the limiting guide protrusion 534 can also apply a force in the rotation direction to the limiting guide groove 511, driving the lifting platform 51 to rotate.

[0059] Reference Figure 6 The positioning cylinder 31 is provided with a mounting through hole 32 having a radius smaller than that of the rotating disk 41. The mounting through hole 32 is coaxial with the positioning cylinder 31. The rotating seat 53 passes through the mounting through hole 32, and the rotating disk 41 is fixedly connected to the lower end surface of the rotating seat 53. A stop ring 531 protruding outward is provided on the outer surface of the rotating seat 53. The portion of the rotating seat 53 located between the rotating disk 41 and the stop ring 531 is provided with a mounting portion 532 adapted to the mounting through hole 32. The mounting portion 532 is rotatably connected to the mounting through hole 32. The stop ring 531 and the rotating disk 41 are respectively located on both sides of the base 3, clamping the base 3 from both sides, and jointly providing vertical limit for the rotating seat 53. A positioning cylinder 31 is further provided on the upper outer end surface of the mounting through hole 32 , and the first connecting portion 12 is sleeved on the positioning cylinder 31 to ensure that the rotation axis of the first connecting portion 12 coincides with the rotation axis of the second connecting portion 22 .
