Description

Technical Field

[0001] This utility model relates to the field of intelligent toilet seat production and manufacturing technology, specifically to a dynamic flushing mechanism and intelligent toilet seat in the absence of electricity. Background Technology

[0002] As people's living standards continue to improve, smart toilet seats are becoming increasingly popular. Existing smart toilet seats generally use a motor as a drive component to extend the spray nozzle for posterior and feminine washes. This usually requires electricity, but in existing bathrooms, to prevent water splashing and electrical leaks, electrical outlets are often not installed around the toilet. This means that when upgrading to a smart toilet seat, it's impossible to connect to electricity; one must either use a long-distance power strip or continue with the conventional non-electric mechanical flushing, unable to experience the full functionality of a smart toilet seat. Furthermore, existing smart toilet seats also cannot function properly in the event of a power outage or short circuit.

[0003] Furthermore, existing smart toilet seats have a fixed spray position after the spray bar extends. However, users have different body types and different seating positions on the smart toilet seat. The fixed spray bar position results in incomplete washing, requiring users to adjust their seating position to expand the washing range. For example, a Chinese utility model patent application, titled "A Spray Washing Device and a Method for Achieving Swinging Spray Washing and a Smart Toilet," publication number CN113235708A, discloses a method using a motor as the driving force, employing a swing drive mechanism to rotate the spray bar axially. The forward and reverse rotation of the motor causes the spray bar to swing circumferentially at a certain angle to expand the washing range. Another method uses a vibration mechanism at the nozzle of the spray bar to change the direction of water jets through vibration. Existing methods are all based on a power source, using a motor to drive a transmission mechanism, ultimately causing the spray bar to swing or vibrate. They cannot be used when there is no power or power failure, resulting in a poor user experience.

[0004] Moreover, existing spray bar swing or vibration methods are complex in structure and lack precision during assembly, making it difficult to control the angle adjustment. This results in an excessively large cleaning area, spraying the entire buttocks, leading to poor cleaning effect and unsatisfactory experience.

[0005] In conclusion, the flushing structure of existing smart toilet seats needs further improvement. Utility Model Content

It solves the problem that the existing flushing structure relies on electricity and cannot flush normally or dynamically with reciprocating motion in the absence of electricity.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The base from which the housing of the water spray assembly is mounted;

[0010] The water spray assembly further includes a spray bar that slides relative to the housing, and an elastic element that drives the spray bar to return to its original position within the housing; the spray bar extends out of the housing based on water pressure and sprays water.

[0011] The transmission assembly drives the water spray component to slide back and forth linearly relative to the base through the force of water flow; the transmission assembly includes a transmission component and a mating part formed in the housing; the transmission component performs circumferential motion and intermittently moves the mating part to drive the housing and the spray bar inside the housing to slide back and forth linearly.

[0012] It also includes a drive unit that uses water flow as a power source and is used to drive the transmission component to rotate.

[0013] Furthermore, the mating part is configured as a racetrack-shaped guide ring formed below the housing. The length direction of the guide ring is arranged along the axial direction of the spray bar, and at least two positions are formed on the inner peripheral wall of the guide ring in the length direction. The two positions are arranged opposite to each other and are engaged with the transmission member to make the water spray assembly in the housing slide and reciprocate relative to the base.

[0014] Furthermore, the transmission component includes a rotating wheel and a plurality of teeth formed on the rotating wheel, which form a pushing surface that cooperates with the gear position in the same rotation direction; wherein, the transmission component extends into the guide ring, and the pushing surface of the teeth is set relative to the gear position, when the pushing surface cooperates with one of the gear positions, so as to drive the water spray assembly to move along the spray rod axial direction, and when the pushing surface passes the gear position, the water spray assembly returns to its original position along the spray rod axial direction.

[0015] Furthermore, the outer periphery of the rotating wheel is provided with at least three teeth, and the teeth are configured as unidirectional teeth; each of the unidirectional teeth is evenly distributed on the outer peripheral wall of the rotating wheel.

[0016] Furthermore, the mating part is configured as a racetrack-shaped guide ring formed below the housing. The length direction of the guide ring is arranged along the axis of the spray bar, and at least two meshing racks are formed on the inner peripheral wall of the guide ring in the length direction. The two meshing racks are arranged opposite to each other and engage with the protruding teeth on the transmission member so that the water spray assembly in the housing can reciprocate in a sliding manner.

[0017] Furthermore, the meshing rack and the guide ring are arranged opposite to each other and staggered along their length.

[0018] Furthermore, the number of teeth provided on the convex tooth is 3-5.

[0019] Furthermore, the drive assembly includes a sealed water chamber, an impeller, and a connecting structure. The sealed water chamber has at least one inlet and one outlet.

[0022] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0023] (1) This utility model provides a dynamic flushing mechanism and a smart toilet seat in the absence of electricity. It has a simple structure, is easy to manufacture, easy to implement and has a low cost. It solves the problem that the existing flushing structure relies on electricity and cannot flush normally or have dynamic flushing with reciprocating motion in the absence of electricity. This utility model uses a water flow drive group and a mechanical transmission group to realize the reciprocating motion of the spray component. That is, the circular motion of the transmission component intermittently moves the mating part of the spray component housing, thereby driving the spray component to slide linearly. The structure is simple and the spraying area of ​​the spray bar is expanded. There is no need to use electric components such as motors and vibration drive components, which improves the flushing area and the user experience. More importantly, it can automatically reciprocate in the absence of electricity, so that the sprayed water has a certain potential energy, making the buttocks cleaner and the range wider.

[0024] (2) The present invention adopts a guide ring type mating part, which is set along the axis of the spray bar, and at least two gears are set in the guide ring. During the movement of the transmission component, one gear is used to drive forward and after disengagement, it is reset and driven backward when it is engaged with the other gear. This cycle repeats. The whole structure is simple and has good stability. Compared with the complex motor drive method, it is easier to control the displacement range. The water spray component is not easy to move excessively and spray to other areas, resulting in a better user experience.

[0025] (3) The transmission component of this utility model uses the cooperation of the rotating wheel and the tooth to achieve intermittent plucking, rather than continuous cooperation, so as to ensure that the water spray component has less resistance when moving in the opposite direction; in addition, this utility model designs the tooth as a one-way tooth, so that when the rotating wheel reverses abnormally, it cannot drive the tooth to move, and will damage or break the gear of the inner wall of the guide ring, thus playing a good protective role.

[0026] (4) This utility model also adopts another meshing rack and tooth engagement method. This method has a simple structure and can maintain a longer and slower reciprocating motion in the meshing state, with high stability. In addition, in order to reduce the range of transitional motion, this utility model sets the number of teeth to 3-5 teeth, which can ensure the reliability of meshing and will not cause transitional displacement, and the assembly is also easier to achieve.

[0027] (5) The drive unit described in this utility model includes a sealed water chamber, an impeller and a connecting structure. The impeller is used as a drive component to directly or indirectly drive the transmission component to rotate. After the water flow impacts the impeller to rotate, the potential energy is stronger. When it is introduced to the spray bar, the water flow with increased velocity and the spray bar in motion have a better rinsing or massaging effect, preventing the water potential energy from being too low and affecting the rinsing experience.

[0028] (6) This utility model also adopts a multi-stage gear reduction structure to avoid excessive speed affecting the cooperation with the guide ring, making the reciprocating motion more enjoyable. Attached Figure Description

[0044] See Figure 1-6 The present invention describes a dynamic flushing mechanism in the absence of electricity, which is used in the spray bar 11 of a smart toilet to dynamically flush the user's buttocks. The dynamic flushing mechanism of this embodiment not only expands the flushing area in the absence of electricity, but also enhances the user experience, similar to a massage.

[0045] This first embodiment illustrates the use of a smart toilet seat with a dynamic flushing mechanism in a power-off state as an example.

[0046] The smart toilet seat described in this embodiment includes a seat body (not shown in the figure), a water inlet assembly 2, and a dynamic flushing mechanism (of course, the smart toilet seat also has various blower and drying functions, which are existing technologies and will not be described in detail). The water spray assembly 1 of the dynamic flushing mechanism is slidably mounted in the base 3. It should be noted that the base 3 is fixed to the seat body by screws. The drive assembly 4 is installed in the seat body and is connected to the water inlet assembly 2 and the spray bar 11.

[0047] The dynamic flushing mechanism in Embodiment 1 includes a base 3, a water spray assembly 1, a transmission group 5, and a drive group 4;

[0048] The base 3 is injection molded, with ears 31 formed at both ends that connect to the mounting positions of the cover plate body, and is fixed to the cover plate body by screws; in addition, the base 3 is hollow inside to allow the housing 12 of the water spray assembly 1 to be movably installed. The movable installation is a sliding fit, which can be guided by slide rails and slide grooves to ensure the smoothness of movement.

[0049] The water spray assembly 1 includes a housing 12, a spray rod 11 that slides relative to the housing 12, and an elastic element that drives the spray rod 11 to return to the housing 12. The spray rod 11 extends out of the housing 12 based on the water flow pressure and sprays water. The spray rod 11 is connected to the sealed water chamber 41 of the water inlet assembly 2 or the drive assembly 4. The water flow pressure pushes one end of the spray rod 11 to compress the internal elastic element (not shown in the figure), and the water outlet end of the spray rod 11 is pushed out of the housing 12. As the water flow continues to flow out, the spray rod 11 is continuously pushed out, and the water flow continues to spray out.

[0050] The transmission group 5 drives the water spray component 1 to slide back and forth linearly relative to the base 3 through the force of the water flow.

[0051] The transmission assembly 5 includes a transmission component 51 and a mating portion 52 formed in the housing 12;

[0052] In this embodiment, the mating part 52 is configured as a guide ring 52A formed below the housing 12 and in the shape of a racetrack. The length direction of the guide ring 52A is arranged along the axial direction of the spray bar 11, and at least two stops 52A1 and 52A2 are formed on the inner peripheral wall of the guide ring 52A in the length direction.

[0053] The two gear positions 52A1 and 52A2 are arranged opposite to each other and are engaged with the transmission component 51 to make the water spray assembly 1 inside the housing 12 slide and reciprocate.

[0054] In this embodiment, the transmission component 51 includes a rotating wheel 511 and a plurality of teeth 512 formed on the rotating wheel 511, which form a pushing surface 5120 that cooperates with the gear positions 52A1 and 52A2 on the housing 12 in the same rotation direction.

[0055] It should be noted that in this embodiment, at least three teeth 512 are provided on the outer periphery of the rotating wheel 511, and the teeth 512 are configured as unidirectional teeth 512 for example; each of the unidirectional teeth 512 is evenly distributed on the outer peripheral wall of the rotating wheel 511.

[0056] The transmission member 51 extends into the guide ring 52A, and the pushing surface 5120 of the prying tooth 512 is positioned relative to the gear positions 52A1 and 52A2. When the pushing surface 5120 engages with one of the gear positions 52A1 and 52A2, it drives the water spray assembly 1 to move axially along the spray rod 11. When the pushing surface 5120 passes over the gear positions 52A1 and 52A2, it drives the water spray assembly 1 to reset axially along the spray rod 11. That is, the transmission member 51 performs a circular motion and intermittently actuates the mating part 52 to drive the housing 12 and the spray rod 11 inside the housing 12 to slide back and forth in a straight line. It should be noted that the intermittent actuation here means that the prying tooth 512 of the transmission member 51 and the mating part 52 are not continuously engaged. After the prying tooth 512 actuates the mating part 52, it releases the mating part 52 with displacement, and then another prying tooth 512 forms an actuating engagement with the mating part 52.

[0057] It also includes a drive unit 4, which is powered by water flow and is used to drive the transmission component 51 to rotate.

[0058] The drive unit 4 includes a sealed water chamber 41, an impeller 42, and a connecting structure 43;

[0059] The sealed water chamber 41 is formed by injection molding to form a water chamber for the impeller 42 to be placed in. It has at least one inlet 411 and an outlet 412. The inlet 411 is connected to the water inlet assembly 2 (i.e., the water inlet valve), and the outlet 412 can be connected to the spray bar 11 or other water outlet components.

[0060] The impeller 42 is mounted in the sealed water chamber 41 via a shaft and is driven to rotate by water flow. The inlet 411 is inclined to correspond to the impact of the impeller 42 blades, ensuring smooth rotation of the impeller 42. Furthermore, the impeller 42 is directly or indirectly connected to the transmission component 51 via a connecting structure 43 to drive the transmission component 51 to rotate. Direct or indirect connection to the transmission component 51 means: direct connection means coaxial connection via a connecting shaft, such as through an anti-rotation groove, directly driving the transmission component 51 to rotate; indirect connection means connection to the transmission component 51 via other reduction structures or other connecting structures 43. In this embodiment, the connecting structure 43 is used as an example of a reduction structure.

[0061] The deceleration structure includes several meshing gears 431; the driving gear 431A among the gears 431 is connected to the impeller 42 to prevent rotation, and the driven gear 431B is coaxially arranged with the transmission component 51 and rotates together; wherein the diameter of the driving gear 431A is smaller than the diameter of the driven gear 431B, thus slowing down the rotation speed of the transmission component 51, and the transmission component 51 engages with the gear 512 more slowly, resulting in a better experience during the movement.

[0062] In actual manufacturing and use:

[0063] (1) Spray bar 11 assembly, which includes two spray bars 11 for posterior wash and feminine wash, housing 12 and built-in elastic element (not shown in the figure) (i.e. spring). One end of the spray bar 11 is the water outlet end 111 (set perpendicular to the axis of the spray bar 11 or at a certain angle), and the other end is the water inlet end, and a pressure bearing surface 112 is formed so that the spray bar 11 can be pushed out relative to the housing 12 after the water flow impacts.

[0064] The elastic element (not shown in the figure) abuts against the inner end face of the housing 12 near the water outlet 111 of the spray bar 11, and the other end abuts against the back of the pressure bearing surface 112 of the spray bar 11, so that the spray bar 11 can be smoothly retracted into the housing 12 when the water pressure is lost.

[0065] After the elastic element and the spray bar 11 are installed into the housing 12, the spray bar 11 is sealed in the housing 12 by ultrasonic welding or other means. Two water inlets C are formed on the housing 12 corresponding to the positions of the two spray bars 11, and the two are respectively connected to the water inlet valve or the water outlet 412 of the sealed water chamber 41.

[0066] (2) The housing 12 is formed by injection molding. In this embodiment, a ring or elliptical guide ring 52A is formed on the lower surface of the housing 12, and the inner wall surface of the guide ring 52A is formed with stops 52A1 and 52A2. It should be noted that the two stops 52A1 and 52A2 are respectively set along the length direction for the transmission component 51 to move. Of course, the stops 52A1 and 52A2 can be added according to actual needs.

[0067] (3) Rotating wheel 511, after injection molding, has several teeth 512 formed on its outer peripheral wall. In this embodiment, three teeth 512 are used as an example. The teeth 512 are unidirectional teeth 512 and each tooth 512 has a push surface 5120 for cooperating with the gear positions 52A1 and 52A2 on the guide ring 52A. When the push surface 5120 of the teeth 512 of the rotating wheel 511 pushes the gear positions 52A1 and 52A2, the housing 12 of the spray bar 11 assembly moves forward or backward along the axis and reciprocates in this way.

[0068] (4) Drive group 4, which includes a sealed water chamber 41 and an impeller 42, both of which are injection molded. The sealed water chamber 41 is a water chamber formed by the cooperation of a shell 44 and an outer cover 45, which is used to install the impeller 42. The impeller 42 is rotatably installed through a shaft and then sealed by the outer cover 45. The gears 431 of the reduction structure are decorated on the outside of the sealed water chamber 41 and are coaxially arranged with the impeller 42. In this embodiment, the small-diameter driving gear 431A is coaxial with the impeller 42 and is anti-rotating, and is driven by several transmission gears 431. Finally, it meshes with the large-diameter driven gear 431B. The driven gear 431B is coaxial with the rotating wheel 511 and is anti-rotating. The anti-rotating connection here refers to the coaxial rotation of the two, which is achieved through the anti-rotation surface.

[0069] (5) After the impeller 42 is installed into the housing 44, the outer cover 45 is then covered and sealed. A speed reduction structure is installed on the side of the housing 44 away from the outer cover 45 and covered with a protective cover 46, leaving only the rotating wheel 511 exposed, and the rotating wheel 511 is placed in the guide ring 52A.

[0070] (6) Base 3, which is hollow and is used to install the housing 12 of the spray bar 11 assembly. In this embodiment, a slide rail is also provided on the base 3 so that the housing 12 can slide relative to the base 3.

[0071] (7) Fix the water inlet assembly 2 and other components to the cover plate body to complete the assembly;

[0072] When using,

[0073] (1) When the user presses the flushing device, the water flows into the sealed water chamber 41 through the water inlet valve of the water inlet assembly and impacts the impeller 42 to rotate through the water inlet 411; then the impeller 42 rotates and drives the coaxial drive gear 431A to rotate; after passing through multiple transmission gears 431, it is output by the large-diameter driven gear 431B.

[0074] (2) The rotating wheel 511, which is coaxially engaged with the driven gear 431B, rotates together;

[0075] (3) At the same time, after the water flow impacts the impeller 42, it flows from the outlet 412 into the housing 12 to impact the spray bar 11. Of course, it can also be directly introduced into the housing 12 from the inlet valve to impact the spray bar 11 extending out of the housing 12. Specifically, after the water flow enters the housing 12, it impacts the pressure-bearing surface 112 at the end of the spray bar 11, causing the spray bar 11 to extend along its axial direction and compress the elastic element (not shown in the figure), and the water flow is sprayed out from the spray bar 11 for posterior washing, feminine washing, or simultaneous rinsing. At this time, the spray bar 11 sprays water at a fixed position.

[0076] (4) The rotating wheel 511 rotates slowly after being decelerated by the deceleration structure. Its outer circumference unidirectional teeth 512 abut against the positions 52A1 and 52A2 of the guide ring 52A of the housing 12. In this embodiment, clockwise rotation is taken as an example. When the teeth 512 push the position 52A1 of the lower wall of the guide ring 52A, it drives the entire housing 12 and the spray rod 11 to move backward a certain distance. Since the spray rod 11 extends with a certain tilt angle, its spray range and angle change after moving a certain distance, thereby achieving the rinsing of the rear of the buttocks. When the teeth 512 push the position 52A2 of the upper wall of the guide ring 52A, the housing 12 and the spray rod 11 are pushed forward a certain distance to achieve the rinsing of the front of the buttocks. This expands the rinsing range. This back-and-forth movement forms a dynamic rinsing sensation, making the rinsing cleaner and having a certain massage function. The rinsing range is expanded, but it will not be excessively expanded and affect the experience.

[0077] Example 2:

[0078] like Figure 1 , 7 As shown in Figure 9, the parts of this embodiment that are the same as those in embodiment one will not be repeated. The difference between this embodiment and embodiment one lies in the structure of the transmission group 5. Specifically, the way the mating part 52 and the transmission component 51 are mated in this embodiment two is different, as detailed below:

[0079] In this embodiment, the mating part 52 is configured as a guide ring 52A formed below the housing 12 and in the shape of a racetrack. The length direction of the guide ring 52A is arranged along the axis of the spray bar 11, and at least two meshing racks 52A3 are formed on the inner peripheral wall of the guide ring 52A in the length direction.

[0080] The two meshing racks 52A3 are arranged opposite to each other and cooperate with the protruding teeth 513 on the transmission member 51 (wherein, in order to prevent excessive displacement, the number of teeth on the protruding teeth 513 is 3-5 teeth). In addition, the meshing racks 52A3 and the guide ring 52A are arranged opposite to each other and staggered in the length direction, so that the water spray assembly 1 in the housing 12 can move in a sliding reciprocating motion.

[0081] During assembly, the convex tooth 513 is fixed to the shaft of the driven gear 431B in a non-rotating manner. When the driven gear 431B rotates, it drives the convex tooth 513 to rotate as well, and then it engages with the two meshing racks 52A3 in the guide ring 52A.

[0082] Due to the misaligned arrangement of the meshing rack 52A3, the rack 52A3 can move forward or backward in reciprocating motion according to its position and direction. Similarly, when the spray bar 11 extends out of the housing 12, it drives the entire spray bar 11 and housing 12 to reciprocate, thereby achieving dynamic rinsing with an expanded range.

[0083] This invention provides a dynamic flushing mechanism and a smart toilet seat in the absence of electricity. Its structure is simple, easy to manufacture, readily achievable, and low-cost. It solves the problems of existing flushing mechanisms that rely on electricity and cannot flush properly or achieve dynamic reciprocating motion in the absence of power. This invention uses a water flow drive group and a mechanical transmission group to achieve the reciprocating motion of the spray component. Specifically, the circular motion of the transmission component intermittently actuates the mating part of the spray component's housing, thereby driving the linear sliding of the spray component. This simple structure increases the spray area of ​​the spray bar and eliminates the need for motors, vibration drives, etc. The electrical components enhance the rinsing area and user experience. More importantly, they automatically reciprocate in the absence of power, giving the sprayed water potential energy for a cleaner, wider-ranging wash of the buttocks. This invention employs a guide ring-type mating part, positioned along the spray bar axis, with at least two positions within the guide ring. During the movement of the transmission components, one position drives forward and, upon disengagement, is reset and driven backward by the other position, repeating this cycle. The entire structure is simple and stable, offering easier control of the displacement range compared to complex motor-driven methods. The components are less prone to excessive movement and spraying into other areas, resulting in a better user experience. The transmission component of this invention utilizes a rotating wheel and a paddle gear to achieve intermittent paddle action, rather than continuous action, thus ensuring less resistance when the water spray assembly moves in the opposite direction. Furthermore, this invention designs the paddle gear as unidirectional, which prevents it from moving when the rotating wheel reverses abnormally, thus protecting it from damage to the guide ring's inner wall. This invention also employs another method of meshing rack and pinion teeth, which is equally simple in structure and allows for longer and slower reciprocating motion in the meshed state. The movement is highly stable. Furthermore, to reduce the range of excessive movement, the number of teeth is set to 3-5, ensuring reliable meshing without causing excessive displacement, and making assembly easier. The drive assembly of this invention includes a sealed water chamber, an impeller, and a connecting structure. The impeller acts as the driving component, directly or indirectly driving the transmission components to rotate. The water flow impacting the rotating impeller generates stronger potential energy, which, when introduced to the spray bar, enhances the rinsing or massaging effect due to the dynamic movement of the spray bar, preventing insufficient water potential energy from affecting the rinsing experience. This invention also employs a multi-stage gear reduction structure to prevent excessively high rotation speed from affecting the fit with the guide ring, making the reciprocating motion more immersive.

[0084] The description of the above specification and embodiments is used to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model.
