DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Referring to the drawings of the specification, a cleaning spray rod transmission structure includes a base 1, on which an arc-shaped guide rail 11 is arranged. It also includes a cleaning spray rod 2 that is curved downward and movably connected to the arc-shaped guide rail 11. It also includes a telescopic motor 01, which is connected to the cleaning spray rod 2 and drives the cleaning spray rod 2 to reciprocate along the arc-shaped guide rail 11.

[0039] Furthermore, a nozzle assembly is also provided at the front end of the cleaning spray bar 2, and a water outlet 21 is provided on the nozzle assembly. The nozzle assembly is connected with a water pipe 22, and the water pipe 22 is connected in the cleaning spray bar 2 and connected to the water inlet end. Specifically, the water pipe 22 made of silicone material is connected to the water inlet joint and the reversing valve of the smart cover to realize the water supply of the cleaning spray bar 2. The water pipe 22 can also be arranged outside the cleaning spray bar 2.

[0040] Through the design of the above structure, the utility model sets the cleaning spray rod 2 into an arc shape and can be slidably set on the base 1. The arc-shaped cleaning spray rod 2 can greatly reduce the overall height of the cleaning module without changing the extension range of the spray rod, which is conducive to realizing the lightweight design of the smart toilet.

[0041] Furthermore, a gear 12 is provided in the base 1, and a rack 23 is provided on the cleaning spray rod 2. The rack 23 is meshed with the gear 12, and the gear 12 is also connected with the telescopic motor 01. In the preferred embodiment given by the utility model, the number of gears 12 is multiple, forming a multi-stage transmission gear set. The rotation of the gear 12 drives the movement of the rack 23 through meshing, thereby realizing the movement of the cleaning spray rod 2 along the arc guide rail 11.

[0042] Furthermore, the nozzle assembly is composed of at least two nozzles 3 of different water types. In the specific embodiment given in the utility model, the number of the nozzles 3 is four, namely the first nozzle 31, the second nozzle 32, the third nozzle 33 and the fourth nozzle 34. The water output type of each nozzle is different and can be flexibly adjusted according to user needs.

[0043] Furthermore, the cleaning spray rod 2 also includes a spray rod body 24, a spiral shaft 25 and a shell 26, the shell 26 is provided with a water hole 261, the spiral shaft 25 is embedded in the spray rod body 24, and the shell 26 is sleeved outside the spray rod body 24, one end of the spiral shaft 25 is matched and connected with the spray head assembly, and the other end of the spiral shaft 25 is matched and connected with a driving member 02. The spray head assembly also includes a spray head shell 51, and the upper end of the spray head shell 51 is provided with a water outlet 52. The driving member 02 is driven, so that the spiral shaft 25 drives the spray head assembly to rotate and then changes the matching position of the spray head 3 and the water outlet 52, thereby changing the water outlet form.

[0044] Furthermore, a recess 54 is provided at the side end of the nozzle housing 51 corresponding thereto, and a rotating shaft 262 is provided at the side end of the housing 26 of the cleaning spray rod 2. The rotating shaft 262 is matched and connected with the recess 54. With the cooperation between the recess 54 and the rotating shaft 262, the nozzle assembly can rotate relative to the housing 26.

[0045] Furthermore, the driving member 02 is driven so that the spiral shaft 25 drives the nozzle assembly to swing within a preset angle range. It should be noted that the swing refers to the nozzle assembly repeatedly rotating forward and backward around the central axis.

[0046] More specifically, the main body of the spiral shaft 25 is a spiral structure, which has great flexibility in the axial direction, that is, the spiral shaft 25 can be easily bent, and is structurally compatible with the curved arc-shaped cleaning spray bar 2. At the same time, increasing the external dimensions of the spiral body can increase the circumferential rigidity of the spiral shaft 25, so that it has a good torque transmission capability. The axial flexibility plus the circumferential rigidity enable the spiral shaft 25 to ensure smooth and accurate torque transmission on the curved cleaning spray bar 2, thereby synchronously driving the switching and swinging of the nozzle assembly, and finally realizing the switching and swinging of the cleaning water type, bringing different sensory experiences to the user.

[0047] More specifically, the spiral shaft 25 can be an injection-molded plastic part, or a metal part made of a spiral spring.

[0048] In addition, the spiral shaft 25 can be used on a linear cleaning spray bar, i.e., a straight rod structure, in addition to being used on an arc-shaped cleaning spray bar 2. In a traditional straight rod structure cleaning spray bar, the driving member and the spray head assembly are directly connected by a rigid shaft, and each connecting component is required to have high coaxiality. However, the use of a spiral shaft can greatly reduce the installation accuracy requirements during installation.

[0049] Through the design of the above-mentioned structure, the present application sets a nozzle assembly that can switch between multiple nozzles 3 at the front end of the cleaning spray rod 2, and sets a driving member 02 for driving the nozzle assembly to switch the nozzle at the rear end. The nozzle assembly and the driving member 02 are connected by a spiral shaft 25. The flexibility of the spiral shaft 25 in the axial direction is utilized to achieve a bent installation, thereby realizing variable-angle power transmission, and there is no need to maintain high coaxiality. The structure is adapted to the curved arc-shaped cleaning spray rod 2, thereby achieving the purpose of having a water type switching function on the curved cleaning spray rod 2. The structure is simple, the functions are diverse, and it is reliable.

[0050] Furthermore, the nozzle assembly also includes a front cover 41 and a rear cover 42. The nozzles 3 of different water types are arranged in a cavity formed by the front cover 41 and the rear cover 42. A fixed shaft 43 for strengthening the connection is also provided between the front cover 41 and the rear cover 42. The nozzles 3 of different water types are respectively connected to the cavity with a sealing ring 4.

[0051] Further, the nozzle assembly also includes a sealing cover 61, and a Y-shaped ring 62 is provided on the rear cover 42, and the Y-shaped ring 62 is matched and connected with the sealing cover 61. The rear cover 42 is provided with an axial hole, and the axial hole passes through the sealing cover 61, and the spiral shaft 25 cooperates with the axial hole to achieve connection with the nozzle assembly. The rear cover 42 and the spiral shaft 25 are also matched and connected with a limit shaft 63, and a sink groove 631 is provided on the limit shaft 63, and a plug hole 241 is provided on the spray rod body 24, and the limit shaft 63 is rotatably fixed to the spray rod body 24 through a pin 64 passing through the plug hole 241. It is also possible that the rear cover 42 is directly connected to the spiral shaft 25, and the rear cover 42 is rotatably fixed to the spray rod body 24. Further, the rear cover 42 is provided with a sink groove 631, and the rear cover 42 is rotatably fixed to the spray rod body 24 through a pin 64 passing through the plug hole 241.

[0052] Specifically, each of the multiple nozzles 3 is equipped with a sealing ring 4 and then installed in the front cover 41 and the rear cover 42 to form an inner core assembly, and the front cover 41 and the rear cover 42 are connected by a fixed shaft 43 to increase the connection strength. The rear cover 42 is provided with a Y-shaped ring 62, which forms a dynamic seal with the sealing cover 61. The inner core assembly is installed in the cavity formed by the nozzle shell 51 and the sealing cover 61, and the inner core assembly can rotate relative to the nozzle shell 51. The nozzle shell 51, the inner core assembly and the sealing cover 61 are assembled together to form a nozzle assembly. The limit shaft 63 is fixed to the spray rod body 24 through a latch 64, and the limit shaft 63 can rotate relative to the spray rod body 24. The nozzle assembly is connected to the limit shaft 63, and the nozzle assembly can rotate relative to the spray rod body 24 under the drive of the limit shaft 63. It can also be that the nozzle assembly is connected to the spiral shaft 25, and the nozzle assembly can rotate relative to the spray rod body 24 under the drive of the spiral shaft 25.

[0053] Furthermore, a limiting groove 53 is provided on the nozzle housing 51, and a limiting rib 242 is provided on the spray rod body 24. The limiting groove 53 is connected with the limiting rib 242, and the width of the limiting groove 53 is greater than the width of the limiting rib 242, so that the nozzle assembly can only rotate within the width of the limiting groove 53. More specifically, in the process of the nozzle 3 spraying the cleaning water column, the driving member 02 can perform repeated forward and reverse movements within a certain angle range, driving the nozzle assembly to also perform corresponding repeated forward and reverse movements, thereby forming a lateral swing of the water pattern, and the forward and reverse angle range of the nozzle assembly shall not exceed the angle range defined by the cooperation of the limiting groove 53 on the nozzle assembly and the limiting rib 242 on the spray rod body 24. Controlling the forward and reverse speed of the driving member 02 can control the speed of the lateral swing of the water pattern. The driving member 02 can also be controlled to pause intermittently during the forward and reverse process to obtain different lateral swing effects. In addition, the telescopic motor 01 can be superimposed to drive the cleaning spray rod 2 to move forward and backward, thereby obtaining a multi-dimensional water discharge effect.

[0054] Furthermore, a first limiting rib 632 is provided on the limiting shaft 63, and a second limiting rib 243 is provided on the spray rod body 24. The driving member 02 drives the limiting shaft 63 to rotate around the spray rod body 24, and when the first limiting rib 632 cooperates with the second limiting rib 243, the driving member 02 can find the initial position. Alternatively, the limiting shaft 63 may not be provided, and the first limiting rib 632 may be directly provided on the spiral shaft 25.

[0055] Furthermore, a fixing seat 7 is also provided at the rear end of the spray rod body 24, and the driving member 02 is matched and connected with the fixing seat 7. The driving member 02 is locked on the fixing seat 7 by screws, and the housing 26 and the fixing seat 7 are then locked on the spray rod body 24 by screws.

[0056] For the schematic diagram of the process of switching nozzle 3, please refer to the attached manual. Fig.10As shown, in the initial position state, the center of the first nozzle 31, the center of the water outlet 52 and the center of the water hole 261 overlap, and the limiting rib 242 of the spray rod body 24 is located in the middle of the limiting groove 53 of the nozzle shell 51. When the nozzle 3 is switched, the driving member 02 drives the inner core assembly to rotate. Since the sealing ring 4 of the inner core assembly and the nozzle shell 51 are in interference fit, the friction between the sealing ring 4 and the nozzle shell 51 can make the inner core assembly rotate with the nozzle shell 51 until the limiting groove 53 of the nozzle shell 51 is limited by the limiting rib 242 of the spray rod body 24. After the limiting groove 53 is limited by the limiting rib 242, the nozzle shell 51 can no longer rotate, and the inner core assembly can continue to rotate under the drive of the driving member 02 to overcome the friction between the sealing ring 4 and the nozzle shell 51. The driving member 02 stops when it rotates to the set position, at which time, the center of the second nozzle 32 overlaps with the center of the water outlet 52. The driving member 02 rotates in the reverse direction to drive the inner core assembly to rotate in the reverse direction, and drives the nozzle housing 51 to rotate in the reverse direction together, and stops after rotating to the set position. At this time, the center of the second nozzle 32, the center of the water outlet 52 and the center of the water hole 261 overlap, completing the switching steps of the nozzle 3, and so on. The switching steps of the remaining nozzles are the same as above.

[0057] In the specific embodiment of the present invention, the first nozzle 31 is a sheet water type, the second nozzle 32 is a bubble water type, the third nozzle 33 is a bulb water type, and the fourth nozzle 34 is a columnar water type. Of course, it can also be set to a flower-shaped water type, a polygonal water type or a shower-shaped water type according to needs.

[0058] The present application also provides a smart toilet, which uses the above-mentioned cleaning spray rod transmission structure. The use process is that the water inlet joint on the fixed seat 7 is connected to the reversing valve of the smart cover plate to realize the water supply of the cleaning spray rod 2. The water pipe 22 connects the sealing cover 61 and the fixed seat 7, and the water flows into the cavity formed by the sealing cover 61 and the nozzle housing 51, and then enters the inner core component from the hole on the front cover 41, and then sprays out from the nozzle 3 aligned with the water outlet hole 52 to form a cleaning water column. Different nozzles 3 can spray cleaning water columns of different water types, thereby achieving different cleaning effects and user experiences.

As mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
