Description

Technical field

[0001] The invention relates to a shower device for smart toilets, in particular a shower device for smart toilets in which a hose is positioned on the side of the spray pipe. State of the art

[0002] With the rapid development of smart toilets, ultra-slim smart toilets are becoming increasingly popular with consumers. As space in the rear (both in height and length) becomes ever more limited, the original single-stage extendable bidet mechanism can no longer meet spatial requirements. Multi-stage extendable bidets (i.e., two-stage extendable bidets) can partially satisfy current spatial requirements. A two-stage extendable bidet incorporates an inner spray tube within the outer spray tube. While the outer spray tube can extend and retract, the inner spray tube can also be extended outwards relative to the outer spray tube. The water channel between the control valve and the inner spray tube is formed by a silicone tube, which supplies the inner spray tube with water.The shower unit's unique design, with its low front and high back, and its mounting method result in relatively substantial height dimensions. Furthermore, the hose is connected to the inner spray bar at the rear of the unit, requiring additional space above the back and maintaining a considerable overall thickness. The hose also necessitates additional components such as fittings and clamps for guidance and positioning. Since the inner and outer spray bars must move forward and backward during operation, restricting the hose's movement presents challenges. This means sufficient clearance must be provided to prevent interference between the hose and other components, as this would impair the shower unit's proper function.Such damage can even lead to chafing of the hose and thus leakage or detachment, thereby impairing long-term product quality. Subject matter of the invention

[0003] The present invention provides an intelligent toilet flushing device which is characterized by an effectively reduced thickness and stable performance, thus overcoming the shortcomings of the prior art.The technical concept of the invention for overcoming the known disadvantages is as follows: Shower device for smart toilets, comprising a stationary bracket, an extendable spray tube arranged to slide back and forth on the stationary bracket, and a hose for introducing water into the extendable spray tube, wherein a water inlet opening belonging to the hose is provided at the rear end of the extendable spray tube, wherein a water spray nozzle is provided at the front end of the extendable spray tube, wherein a side cover is arranged on the side of the stationary bracket, wherein the side cover has a receptacle in which the hose is positioned, and wherein the water inlet opening of the extendable spray tube is arranged on a side of the extendable spray tube that faces the side cover.

[0004] In an advantageous embodiment, the water inlet opening is equipped with a first adapter, wherein one end of the hose is in plug connection with the first adapter, wherein a second adapter is further arranged on the side cover, and wherein the other end of the hose is in plug connection with the second adapter.

[0005] In an advantageous embodiment, the hose is arranged in a C-shape in the vertical plane.

[0006] In an advantageous embodiment, a gear and a meshing rack are also included, wherein the gear is attached to the stationary support, wherein one end of the rack is connected to the extendable spray tube, wherein a movement of the rack causes the extendable spray tube to slide back and forth, and wherein the side cover covers the gear and the rack.

[0007] In an advantageous embodiment, an electric motor is also provided to rotate the gear and to drive the rack for extension and retraction, wherein the electric motor is attached to the side of the stationary bracket, and wherein the electric motor and the side cover are attached to the left and right sides of the stationary bracket, respectively.

[0008] In an advantageous embodiment, a rotating drum, a steel band wound onto the rotating drum, and an electric motor that drives the rotating drum and releases or winds up the steel band are also included, wherein the electric motor and the rotating drum are attached to the stationary support, wherein the free end of the steel band is connected to the extendable spray tube, and wherein the steel band sets the extendable spray tube in a sliding motion.

[0009] In an advantageous embodiment, the extendable spray tube comprises an outer spray tube, an inner core tube provided within the outer spray tube and fixed relative to the position of the outer spray tube, and an inner spray tube slid back and forth within the outer spray tube and enclosing the inner core tube, wherein a sealing ring is provided between the inner spray tube and the inner core tube, wherein the water spray nozzle is connected to the front end of the inner spray tube, wherein the water inlet opening is provided at the rear end of the inner core tube, and wherein, when using a rack, the rack is connected to the inner spray tube, and when using a steel band, the steel band is connected to the inner spray tube.

[0010] In an advantageous embodiment, a plug is provided at the rear end of the inner core tube, which is partially inserted into the outer spray tube and is in clamping connection with the outer spray tube, with the water inlet opening being located on the part of the plug that is not inserted into the outer spray tube.

[0011] In an advantageous exemplary embodiment, an elastic stop pin is provided at the rear end of the inner spray tube, wherein a locking step is provided on the front part of the inner wall of the outer spray tube, wherein, during a forward movement of the inner spray tube, the elastic stop pin engages with the locking step, causing the inner spray tube to drive the outer spray tube to slide forward together.

[0012] In an advantageous embodiment, a front elastic locking mechanism is provided, which acts between the rear section of the inner spray tube and the front section of the outer spray tube, wherein a rear elastic locking mechanism is arranged between the rear section of the outer spray tube and the stationary support, wherein the engagement force of the front elastic locking mechanism is less than the engagement force of the rear elastic locking mechanism, wherein in operation the inner spray tube extends forward, wherein after the locking of the front elastic locking mechanism the inner spray tube pulls the outer spray tube forward and the rear elastic locking mechanism releases, wherein during retraction the inner spray tube takes the outer spray tube with it to slide backward together, whereby the front elastic locking mechanism releases.when the rear elastic lock is in contact between the outer spray tube and the stationary bracket, the inner spray tube then moves into the outer spray tube until it rests against the outer spray tube, and the inner spray tube then pushes the outer spray tube further backward, thereby engaging the rear elastic lock.

[0013] In an advantageous embodiment, the extendable spray tube comprises an outer spray tube, an inner spray tube which can slide back and forth in the outer spray tube, and a spring element which is clamped between the outer spray tube and the inner spray tube, wherein, when using a rack, the rack is connected to the outer spray tube, whereas, when using a steel band, the steel band is connected to the outer spray tube, wherein the water spray nozzle is arranged at the front end of the inner spray tube, wherein the water inlet opening is arranged at the rear end of the outer spray tube, wherein an axially movable baffle plate is arranged above the rear opening of the inner spray tube, wherein a sealing ring surrounding the spray tube is arranged at the rear end of the inner spray tube, and wherein the inner wall of the outer spray tube has a shoulder near the front end.When water flows into the outer spray tube, it presses against the baffle plate to close the opening at the rear end of the inner spray tube. The water then propels the inner spray tube forward, so that it protrudes from the outer spray tube. When the sealing ring and baffle plate press against the shoulder, the shoulder lifts the baffle plate and opens the front opening of the inner spray tube. After the water flow stops, the spring element retracts the inner spray tube into the outer spray tube.

[0014] In an advantageous embodiment, the spring element surrounds the inner spray tube, with an internal projection being provided at the opening of the front end of the inner wall of the outer spray tube, which blocks the spring element.

[0015] Compared to the state of the art, the present technical concept offers the following advantages: 1. The hose is located on the side of the stationary bracket and the extendable spray lance, positioned within the recess of the side cover. Therefore, the hose does not occupy any space above the extendable spray lance, particularly at the rear end, significantly reducing the thickness of the bidet attachment for smart toilets. Furthermore, the hose's position within the recess of the side cover ensures it remains securely in place even during movement, preventing interference and friction between the hose and other components. This enhances the stability and lifespan of the bidet attachment. 2. The two ends of the hose are each connected to a first and second adapter, making installation exceptionally easy and providing a secure hose connection. 3.The C-shaped arrangement of the hose is advantageous for extension and retraction and prevents misalignment. 4. The side cover not only accommodates the hose but also covers the gear and rack, eliminating the need for additional parts of the shower device and simplifying the design. 5.

[0017] As in the Figures 1 to 8As shown, the shower device for smart toilets comprises a stationary bracket 10, an extendable spray tube 20 arranged to slide back and forth on the stationary bracket 10, and a hose 30 for introducing water into the extendable spray tube. A water inlet opening 21 associated with the hose is provided at the rear end of the extendable spray tube, and a water spray nozzle 22 is provided at the front end of the extendable spray tube. During operation, the extendable spray tube 20 slides forward along the stationary bracket 10, and the water flow passes through the hose 30 into the extendable spray tube to be sprayed outwards from the water spray nozzle 22 for cleaning.A side cover 40 is connected to the stationary bracket 10, meaning that the side cover 40 is located on the side of the stationary bracket 10. The stationary bracket 10 and the side cover 40 can be a single part or a structure with two connected elements. The side cover 40 has a receptacle 42 in which the hose 30 is positioned. The water inlet opening 21 of the extendable spray lance 20 is located on one side of the extendable spray lance that faces the side cover 40. During operation, the extendable spray lance 20 slides forward along the stationary bracket 10, pulling the deforming hose 30. The hose is held securely within the receptacle 42 and is located on one side of the extendable spray lance 20 and the stationary bracket 10.The hose is lower than the extendable spray bar 20, so the hose does not increase the thickness of the shower fitting. Typically, the height of the top of the side cover 40 is also lower than the height of the top of the extendable spray bar 20.

[0018] Preferably, the water inlet opening 21 is equipped with a first adapter 23, with one end of the hose 30 being connected to the first adapter via a push-fit connection. A second adapter 44 is attached to the side cover 40, with the other end of the hose being connected to the second adapter via a push-fit connection. The first adapter 23 is connected to the extendable spray lance 20 and can securely pull the hose 30, even under deformation. The second adapter 44 is attached to the side cover 40 and enables secure positioning of the hose within the receptacle 42.

[0019] Preferably, the hose 30 is arranged in a C-shape in the vertical plane.

[0020] Preferably, the assembly also comprises a gear 51 and a meshing rack 52, wherein the gear 51 is attached to the stationary support 10, one end of the rack 52 being connected to the extendable spray tube 20, movement of the rack causing the extendable spray tube to slide back and forth, and wherein the side cover 40 covers the gear and the rack. During operation, the spray tube 20 is extended and retracted along the stationary support by the gear and the rack, the gear being able to be rotated electrically or hydraulically. Preferably, an electric motor 53 is also provided to rotate the gear 51 and to drive the rack for extension and retraction. The electric motor is mounted on the side of the stationary support 10, with the electric motor 53 and the side cover 40 being attached to the left and right sides of the stationary support 10, respectively.

[0021] Alternatively, the gear can also be set in motion by water power. Furthermore, the gear and rack construction can also be replaced by a rotating drum and steel band construction, in which, for example, an electric motor sets the rotating drum in motion and the steel band is wound around the drum. Rotation of the electric motor drives the steel band, causing it to extend or retract. The free end of the steel band is connected to the extendable spray nozzle, and the steel band sets the extendable spray nozzle in a sliding motion.

[0022] In an advantageous embodiment, the extendable spray tube 20 comprises an outer spray tube 20-1, an inner core tube 20-2 provided within the outer spray tube and fixed relative to the position of the outer spray tube, and an inner spray tube 20-3 slid back and forth within the outer spray tube and enclosing the core tube, wherein a sealing ring 24 is provided between the inner spray tube 20-3 and the inner core tube 20-2, wherein the water spray nozzle 22 is connected to the front end of the inner spray tube 20-3, wherein the water inlet opening 21 is provided at the rear end of the inner core tube 20-2, and wherein the rack 52 is connected to the inner spray tube 20-2 (in the case of using a rotary drum and a steel band, the steel band is connected to the inner spray tube). In operation, the electric motor 53 first drives the inner spray tube 20-3 in order to extend it out of the outer spray tube 20-1.After the inner spray tube and the outer spray tube enter a clamping position, the outer spray tube 20-1 slides along the stationary support 10 and water flows through the hose 30 and the water inlet opening 21 into the inner core tube 20-2, then into the inner spray tube 20-3 and finally out of the water spray nozzle 22.

[0023] Advantageously, a plug is provided at the rear end of the inner core tube 20-2, which is partially inserted into the outer spray tube 20-1 and is clamped to the outer spray tube. The water inlet opening 21 is located on the part of the plug that is not inserted into the outer spray tube.

[0024] Advantageously, an elastic stop pin is provided at the rear end of the inner spray tube 20-3, and a locking step is provided on the front section of the inner wall of the outer spray tube 20-1. When the inner spray tube moves forward, the stop pin engages with the locking step, causing the inner spray tube to drive the outer spray tube forward together. It is understood that the relative extension and retraction movements and the positioning of the inner and outer spray tubes can also be achieved by prior art designs. As in the Figure 9 and 10As shown, for example, a front elastic lock 60 is provided, which acts between the rear section of the inner spray tube 20-3 and the front section of the outer spray tube 20-1. A rear elastic lock 70 acts between the rear section of the outer spray tube 20-1 and the bracket 10. The engagement force of the front elastic lock 60 is less than the engagement force of the rear elastic lock 70. In operation, the front elastic lock 60 is initially released, and the rear elastic lock 70 remains locked. Driven by the electric motor, the inner spray tube 20-3 initially extends forward relative to the outer spray tube 20-1.Subsequently, after the front elastic lock 60 is locked, the inner spray tube 20-3 pulls the outer spray tube 20-1 forward, releasing the rear elastic lock 70 and allowing the outer spray tube 20-1 to slide forward along the stationary support 10. During the retraction phase, due to the engagement of the front elastic lock 60, the inner spray tube 20-3 initially carries the outer spray tube 20-1 with it to slide backward together. When the rear elastic lock 170 is positioned between the outer spray tube and the stationary support, the front elastic lock 60 releases. The inner spray tube 20-3 moves into the outer spray tube 20-1 until it rests against the outer spray tube. The inner spray tube 20-3 then pushes the outer spray tube 20-1 further backward, causing it to slide further backward and the rear elastic lock 70 engages. Second embodiment

[0025] As in the Figure 11 and 12As shown, the difference between the second embodiment and the first embodiment lies in the design of the extendable spray tube. In the present embodiment, the extendable spray tube comprises an outer spray tube 25a, an inner spray tube 26a that can slide back and forth within the outer spray tube, and a spring element 27a that is clamped between the outer and inner spray tubes. The rack is connected to the outer spray tube 25a. The water spray nozzle is located at the front end of the inner spray tube 26a, and the water inlet opening 21a is located at the rear end of the outer spray tube 25a. An axially movable baffle plate 28a is located above the rear opening of the inner spray tube 26a. A sealing ring 29a, surrounding the spray tube, is located at the rear end of the inner spray tube.The inner wall of the outer spray tube 25a has a shoulder 251 near its front end. During operation, as water flows through the hose and water inlet opening 21a into the outer spray tube 25a, the water first presses against the baffle plate 28a to close the rear opening of the inner spray tube 26a, meaning the baffle plate covers the inner spray tube. The water flow then propels the inner spray tube 26a forward, so that it protrudes from the outer spray tube 25a. When the sealing ring 29a and the baffle plate 28a press against the shoulder 251, the shoulder 251 lifts the baffle plate 28a, thus opening the front opening of the inner spray tube 26a, allowing the water flow to enter the inner spray tube. After the water flow is interrupted, the spring element 27a retracts the inner spray tube 26a into the outer spray tube 25a.Since the rack is connected to the outer spray tube 25a, the rack drives the outer spray tube so that the extendable spray tube slides on the stationary support 10.

[0026] Preferably the spring element 27a surrounds the inner spray tube 26a, wherein an internal projection 252 is provided at the opening of the front end of the inner wall of the outer spray tube 25a, which blocks the spring element 27a.

[0027] The foregoing descriptions merely highlight advantageous embodiments of the invention, without limiting its scope. All equivalent modifications or embodiments within the scope of the present invention and the description herein are also covered by the scope of protection of the present invention.
