Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, and in particular to a spray assembly for an intelligent toilet and an assembly method of the spray assembly. Background Art

[0002] Nowadays, with the popularization of intelligence, smart toilet seats are also widely used in various homes and public places;

[0003] Although the functions of the existing smart toilet covers are gradually improved, there are still some deficiencies in the details. For example, the existing smart toilet covers are large in size, especially thick, not beautiful in overall appearance, inconvenient to use, and occupy a large space. The specific reasons are: the overall height of the smart toilet cover depends on the height of the spray rod; the spray pipe extends from the inside of the smart toilet cover or retracts, which requires a motor to drive. The gear on the motor meshes with the rack on the spray rod to drive the spray rod to slide relative to the shell. The above structure means that the motor must be set close to the water outlet so that the spray rod can be moved; therefore, the height composed of the overall height of the spray pipe and the size of the motor is the most basic height of the smart toilet cover, so the existing smart toilet cover is very thick and has poor appearance; in addition, since the motor of the smart toilet cover is close to the spray rod injection port, it is easy to be damaged by moisture, which seriously affects its service life;

[0004] In summary, the spray cleaning component of today's smart toilet lids still has room for improvement. Summary of the invention

[0023] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The spray assembly and assembly method of the spray assembly for an intelligent toilet provided by the technical solution are simple in structure, simple in manufacture and easy to implement. The first motor is placed at the rear of the base, and the spray rod is driven by the transmission structure to make the spray rod slide relative to the base. This design not only plays a good protective role for the first motor, but also the toilet cover only needs to meet the height of the spray rod when designing the thickness. The overall thickness can be greatly reduced, realizing a small space-occupying and exquisite intelligent toilet cover;

[0025] 2. The present invention further provides a water distribution unit, so that the spray rod has multiple flushing functions; the switching body of the water distribution unit is connected to the water and air inlet member by a first hose, and the curved section of the first hose is located outside the curved section of the second hose (that is, the two tubes are arranged up and down), so that the volume of the base can be reduced (that is, the width of the base is reduced), so that the volume of the entire spray washing assembly is reduced, and the effect of reducing the thickness of the intelligent toilet is further achieved;

[0026] 3. The width of the accommodating cavity of the base of the present invention is greater than or equal to the outer diameter of the hose with the largest diameter, and less than the sum of the outer diameters of the two hoses, and the length of the first hose is greater than the length of the second hose; specifically: during the movement of the spray rod, the first and second hoses extend or bend with the spray rod, and the above structure can ensure that when the two hoses slide with the spray rod, the bending or stretching direction of the two hoses is consistent with the direction of the spray rod, and the first and second hoses maintain relative positions when bending or stretching, thereby effectively ensuring that the first and second hoses are not entangled with each other, and the phenomenon of hoses interlacing will not occur, ensuring smooth movement, and preventing hose interlacing from affecting the normal operation of the spray washing assembly;

[0027] 4. The present invention adopts a second motor to drive the switching body in the water distribution unit, and the switching body corresponds to any water channel on the spray rod to conduct the water outlet; the conductive wire of the second motor is arranged in parallel with the first and second hoses and is not staggered, and is located outside the curved arc section of the first hose. This arrangement enables the conductive wire to remain parallel to the first and second hoses and maintain a relative position when the second motor slides with the spray rod, thereby preventing the first and second hoses from staggering and entanglement with the conductive wire;

[0028] 5. The present invention also provides a harness structure, through which the length of the conductive wire between the wire buckle and the second motor is adjusted to prevent the conductive wire from being entangled with the first and second hoses when it is too long or too short;

[0029] 6. The water inlet and air inlet member of the present invention is arranged at the middle position of the bottom of the base and is located between the first motor and the spray port of the spray rod; this makes the length of the first and second hoses the shortest. If the water inlet and air inlet member is close to the spray port of the spray rod, the first and second hoses will be too long; if it is close to the first motor, the first and second hoses will be arched when the spray rod moves, which occupies a large space;

[0030] 7. The water inlet and air inlet member of the present invention is installed on the base and is located near the transmission belt. When the water inlet and air inlet member is installed and fixed by the mounting structure, the transmission belt can be supported to tension the transmission belt. This design is not only compact in structure and ingenious in layout, but also realizes dual functions of one object, ensures effective transmission between the first motor and the spray rod, and realizes intelligent and precise control;

[0031] 8. The present invention provides an assembly groove and an assembly hole on the cavity wall of the accommodating cavity of the base, and the assembly groove is a triangular structure. The water inlet part and the air inlet part of the water inlet and air inlet member are sequentially installed from the entrance of the triangular assembly groove, and the water inlet and air inlet member is rotated so that the limiting protrusion of the water inlet and air inlet member is matched with the assembly hole; the limiting protrusion is limited and fixed by the assembly hole, and the water inlet part and the air inlet part enter the two limiting ends (the first end and the second end) of the triangular assembly groove respectively, so that the entire water inlet and air inlet member is stably installed on the base. At the same time, in the process of rotating the water inlet and air inlet member, the supporting part also presses against the outside of the transmission belt to play the role of tensioning the transmission belt;

[0032] 9. The installation method of the spray washing assembly described in the present invention is brief and can be installed by hand without any tools. In addition, the overall installation cost is low, the efficiency is high, and it is easy to maintain and replace; it has good stability, especially after installation, it can stably press against the conveyor belt to achieve the tensioning function.

[0050] See also Figures 1 to 5The present invention discloses a spray cleaning assembly for a smart toilet cover, which is constructed on the smart toilet cover, drives the spray rod 1 to extend from the main body of the smart toilet cover to the toilet bowl through a driving device, and cleans the buttocks by spraying clean water; the existing smart toilet cover is too thick, too heavy and occupies a large space, giving a heavy visual effect as a whole, and of course there is no exquisiteness; and one of the important reasons for the thickness is that a driving motor is arranged at the position where the spray rod 1 extends out of the smart toilet cover, and the volume of the driving motor plus the volume of the spray rod 1 is the basic thickness that the smart toilet cover must first ensure. Based on this thickness, the cover body needs a larger space to flip relative to the seat body on which the spray rod 1 is installed, so the height of the entire cover body has to be increased (basically due to the height of the seat body being flush), which is one of the main reasons for the overall thickness of the existing smart toilet cover; and the spray assembly provided by the present invention effectively solves the above-mentioned defects;

[0051] The spray cleaning assembly mainly includes the following components: a spray rod 1, a base 2, a first motor 3, a second motor 4, a driving gear 51, a double-tooth transmission wheel 52, a transmission belt 53, a water and air inlet member 6, a switching body 71, a self-cleaning connector 72, a wiring harness structure 73, a sterilization unit 8 and a spring 9;

[0052] The base 2 is provided with a slideway 2A, a guide portion 20 formed at the end of the base 2, and a receiving cavity 21; the receiving cavity 21 is constructed by two side walls of the base 2, and the two side walls are correspondingly provided with an assembly groove 22 and an assembly hole 23 for installing the water inlet and air inlet member 6;

[0053] The first motor 3 is mounted on the base 2 and is away from the end of the spraying port of the spraying rod 1, and drives the spraying rod 1 to slide along the base 2 and reciprocate through the guide part 20 through the transmission structure 5;

[0054] Transmission structure 5, such as Figure 5 As shown, it includes a driving gear 51, a double-toothed transmission wheel 52 and a transmission belt 53; the driving gear 51 is locked with the output shaft of the first motor 3; the double-toothed transmission wheel 52 is respectively matched with the transmission belt 53 and the tooth groove on the spray rod 1; it should be noted that the spray rod 1 is provided with a rack along its axial direction, and the rack is meshed with the double-toothed transmission wheel 52; the double-toothed transmission wheel 52 of the present invention includes a primary gear disc 521 and a secondary gear disc 522, the primary and secondary gear discs 521, 522 are coaxially arranged, and are installed in the accommodating cavity 21 through a rotating shaft, wherein the primary gear disc 521 is matched with the rack of the spray rod 1, and the secondary gear disc 522 is matched with the driving gear 51 through a transmission belt 53 to realize power transmission;

[0055] The first motor 3 drives the driving gear 51 to rotate, and the transmission belt 53 links the double-toothed transmission wheel 52 to drive the spray rod 1 to move along the slideway 2A of the base 2. The first motor 3 is rearwardly arranged at the rear side of the base 2 (i.e., away from the water outlet of the spray rod 1). Therefore, the overall thickness of the toilet cover only needs to meet the height of the spray rod 1, and a thin and light intelligent toilet cover can be easily realized.

[0056] On the basis of reducing the thickness, the overall function needs to be ensured. The present invention also provides a water separation unit, which includes a water and air inlet member 6, a switching body 71 and a self-cleaning joint 72;

[0057] The spray rod 1 is provided with a plurality of water channels 10 (the plurality of water channels 10 include functional water channels such as buttock washing, feminine washing, self-cleaning, and strong washing), and the water inlet of each of the water channels 10 is switched and connected with the water outlet of the switching body 71; it should be noted that the switching body 71 is moved relative to the spray rod 1 by the second motor 4 provided on the spray rod 1, and the second motor 4 and the switching body 71 also adopt a gear rack structure to realize transmission;

[0058] The water inlet and air inlet member 6 is connected to the switching body 71 through the first hose A. It should be noted that the water inlet and air inlet member 6 is arranged between the first motor 3 and the guide portion 20, so that the required length of the first hose A is minimized. The length of the first hose A is reasonably arranged to achieve the effect of reducing the overall volume of the spray bar 1 assembly.

[0059] The water inlet and air inlet member 6 comprises a water inlet portion 61, an air inlet portion 62, a water outlet portion 63, a supporting portion 64, a connecting portion 65 and a limiting protrusion 66; the water inlet portion 61 and the air inlet portion 62 are located on one side of the water outlet portion 63; the limiting protrusion 66 and the connecting portion 65 are connected to the other side of the water outlet portion 63 through the supporting portion 64, and the water inlet portion 61, the air inlet portion 62, the supporting portion 64 and the limiting protrusion 66 are parallel to each other and perpendicular to the axial direction of the water outlet portion 63; the connecting portion 65 is parallel to the axis of the water outlet portion 63; it should be noted that one end of the first hose A is connected to the water outlet portion 63, and the other end is connected to the switching body 71; the water inlet and air inlet member 6 is installed on the base 2 through an assembly structure, and the supporting portion 64 of the water inlet and air inlet member 6 is pressed against the transmission belt 53 to tighten the transmission belt 53;

[0060] The self-cleaning joint 72 is installed below the guide portion 20 and is connected to one of the water paths 10A of the spray bar 1 through the second hose B. That is, when the outer wall of the spray bar 1 needs to be cleaned, the switching body 71 is connected to one of the water paths 10A of the spray bar 1, and water flows through the second hose B to the self-cleaning joint 72, and is sprayed from the self-cleaning joint 72 to the outer wall of the spray bar 1 for cleaning;

[0061] The curved section of the first hose A is located outside the curved section of the second hose B (the outside of the curved section of the second hose means that the curved section of the first hose is farther away from the center of the circle roughly defined by the contour of the curved section of the second hose than the curved section of the second hose); the first and second hoses A and B are rubber hoses that can be bent; the present invention arranges the first hose A above the second hose B to further reduce the volume of the spray bar 1 assembly;

[0062] In order to prevent the first and second hoses A and B from being entangled with each other when the spray bar 1 moves, the width of the accommodating cavity 21 is set to be greater than the outer diameter of one hose and less than the sum of the outer diameters of the two hoses, and the length of the first hose A is greater than the length of the second hose B. This layout is compact and ingenious, and will not interfere with the movement of the spray bar 1. At the same time, the two hoses will not cause water flow to be unsmooth due to squeezing. In addition, a spring 9 is sleeved on the outer wall of the second hose B to prevent the second hose B from being excessively bent. The second hose B is located within the inner diameter range of the first hose A during the bending process, and is prone to excessive bending. The spring 9 is set to not only ensure that the second hose B will not be excessively bent, but also reduce the friction and interference between the first and second hoses A and B even if they collide.

[0063] In addition, if Figure 1-3 As shown in FIGS. 6 and 7 , the conductive wire 40 of the second motor 4 of the present invention is arranged in parallel with the first and second hoses A and B, and is located on the outside of the first hose A; this arrangement enables the conductive wire 40 to remain parallel to the first and second hoses A and B and maintain a relative position when the second motor 4 slides with the spray rod 1, thereby preventing the first and second hoses A and B from interlacing and entanglement with the conductive wire 40; more specifically, anti-entanglement is achieved by arranging a harness structure 73; the harness structure 73 includes a wire buckle 731 and a receiving groove 732, and the receiving groove 732 is formed at the bottom of the base 2; the wire buckle 731 is slidably sleeved on the conductive wire 40, and is installed on the receiving groove 732 to adjust the distance between the conductive wire 40 from the wire buckle 731 to the second motor 4;

[0064] The water inlet and air inlet member 6 is mounted on the bottom of the base 2 through a mounting structure, and is located between the first motor 3 and the spray port of the spray bar 1, and the supporting portion 64 of the water inlet and air inlet member 6 is pressed against the transmission belt 53 to tighten the transmission belt 53; specifically, the mounting structure includes a mounting groove 22 and a mounting hole 23 opened on both side walls of the accommodating cavity 21 of the base 2;

[0065] The assembly groove 22 and the assembly hole 23 are respectively arranged on the two side walls of the accommodating cavity 21; the assembly hole 23 is provided for the limiting protrusion 66 to be installed; wherein, the assembly groove 22 is provided for the water inlet portion 61 and the air inlet portion 62 to be installed; the assembly groove 22 comprises an opening 221 and a first end 222 and a second end 223; the opening 221 is provided on the side wall edge of the base 2, and the opening 221 and the first end 222 and the second end 223 constitute a triangular assembly groove 22; the first end 222 and the second end 223 are provided for the water inlet portion 61 and the air inlet portion 62 to be installed respectively;

[0066] The assembly method of the spray bar 1 assembly is as follows: Figure 1-8 (shown)

[0067] 1. Install the spray rod 1 into the corresponding slide groove of the base 2, so that the spray rod 1 slides along the slide groove, and the nozzle of the spray rod 1 moves relative to the guide part 20;

[0068] 2. Fix the first motor 3 to the side wall of the base 2, and make its output shaft engage with the driving gear 51 to prevent rotation;

[0069] 3. Fix the double-toothed transmission wheel 52 in the accommodating cavity 21 through a pin shaft or a rotating shaft, and make the first-stage toothed disc 521 mesh with the spray rod 1, and the second-stage toothed disc 522 cooperate with the driving gear 51 through the transmission belt 53;

[0070] Fourth, fix the self-cleaning joint 72 below the guide part 20 and align the water outlet with the spray bar 1, then insert the second hose B with the spring 9 from the accommodating cavity 21, so that the two ends of the second hose B are connected to the spray bar 1 and the self-cleaning joint 72 respectively;

[0071] 5. The second motor 4 is fixed to the spray rod 1, and cooperates with the switching body 71 through the gear transmission group, and can drive the switching body 71 to move relative to the spray rod 1, and then one end of the first hose A is connected to the switching body 71, and the other end is connected to the water outlet 63 of the water and air inlet member 6;

[0072] 6. The water inlet part 61 and the air inlet part 62 of the water inlet and air inlet member 6 are sequentially installed from the opening 221 at the edge of the side wall of the base 2, with the water inlet part 61 entering first and the air inlet part 62 entering later into the assembly groove 22 (such as Fig. 9 22), until the water inlet portion 61 is moved to the first end 222, the air inlet portion 62 is also located between the opening 221 and the second end 223, and the water outlet portion 63, the supporting portion 64, the connecting portion 65 and the limiting protrusion 66 are located in the accommodating cavity 21; it should be noted that at this time, the supporting portion 64 has not yet abutted against the transmission belt 53, and the limiting protrusion 66 has not yet entered the assembly hole 23 (as shown in FIG. Fig.10 shown);

[0073] 7. Taking the axis of the water inlet 61 at the first end 222 as the axis (e.g. Fig.11 As shown in the figure, the water and air inlet member 6 is rotated so that the air inlet portion 62 enters the second end 223 of the assembly groove 22 and the connection portion 65 is elastically deformed and the linkage limiting protrusion 66 falls into the assembly hole 23. At the same time, the supporting portion 64 is rotated by a certain angle and abuts against the outer wall of the transmission belt 53 to tighten the transmission belt 53; and the first hose A is located in the accommodating cavity 21 and above the second hose B;

[0074] 8. Adjust the length of the conductive wire 40 of the second motor 4 through the wire buckle 731 (this length refers to the length from the second motor 4 to the wire buckle 731), adjust the length, and set it above the first hose A, then insert the wire buckle 731 into the hook part, and finally the conductive wire 40, the first hose A, and the second hose B are arranged in order from top to bottom, and can maintain relative positions during the movement without entanglement;

[0075] 9. Install the ultraviolet germicidal lamp 8 on the guide part 20 to complete the assembly of the entire spray bar 1;

The switching body 71 is controlled by the displacement of the second motor 4 to correspond to the corresponding water channel 10, and the water and gas are then sprayed out from the conducted water flow, ultimately realizing functions such as butt washing, women's washing, self-cleaning, and strong washing.

[0077] The above specification and description of the embodiments are used to explain the protection scope of the present invention, but do not constitute a limitation on the protection scope of the present invention.
