Description

Technical Field

[0001] This invention relates to an intelligent toilet cleaner, and more particularly to an intelligent toilet cleaner without a built-in hose. Background Technology

[0002] With the rapid development of smart toilets, ultra-thin smart toilets are increasingly favored by consumers. The space behind smart toilets is becoming increasingly limited (in height and length), and the original single-stage telescopic washer can no longer meet the space requirements. Multi-stage telescopic (i.e., two-stage telescopic) washer can solve some of the current space constraints. A two-stage telescopic washer consists of an inner spray pipe nested inside an outer spray pipe. The inner spray pipe extends outward relative to the outer spray pipe and is connected to it via a flexible connecting pipe to form a water supply path. However, in existing two-stage telescopic washer systems, the inner and outer spray pipes need to extend and retract back and forth during operation. This means the inner spray pipe repeatedly extends and retracts relative to the outer spray pipe, while the flexible connecting pipe (which transports water to the inner spray pipe) needs to extend into the outer spray pipe and move back and forth with it. This movement causes the flexible connecting pipe to constantly scrape against the outer spray pipe, potentially leading to leaks or even detachment of the flexible connecting pipe. The stability and lifespan of the product need improvement. Summary of the Invention

[0003] This invention provides an intelligent toilet washer that eliminates the need for a flexible connecting tube, thus avoiding leakage and detachment. This overcomes the shortcomings of the prior art. The technical solution adopted by this invention to solve its technical problem is as follows:

[0004] A smart toilet washer includes a fixed base, an outer spray pipe reciprocatingly sliding on the fixed base, and an inner spray pipe reciprocatingly sliding within the outer spray pipe. The inner spray pipe has a spray nozzle at its front end and also includes an inner core tube. The inner core tube is disposed within the outer spray pipe and is positionally fixed relative to the outer spray pipe. The inner spray pipe is retractably fitted over the outer core tube. A sealing ring is provided between the inner spray pipe and the inner core tube, and the sealing ring is fitted onto the outer wall of the front end of the inner core tube. The inner cavity of the inner spray pipe communicates with the inner cavity of the inner core tube to form a water outlet path. The water outlet path is connected to the spray nozzle. The rear end of the inner core tube has a water inlet connected to the water outlet path.

[0005] In a preferred embodiment: the inner nozzle is provided with an elastic stop pin at its rear end, and the inner wall of the outer nozzle is provided with a locking step at its front end. After the elastic stop pin moves forward with the inner nozzle and engages with the locking step, the inner nozzle can push the outer nozzle to slide forward together.

[0006] In a preferred embodiment, the device further includes a meshing gear and a rack. The gear is disposed on the fixed base, and the end of the rack is connected to the inner nozzle. When the rack moves, it causes the inner nozzle to extend and retract, and the outer nozzle to slide.

[0007] In a preferred embodiment, the device further includes a motor for driving the gear to rotate so as to move the rack telescopically, the motor being mounted on the side of the mounting base.

[0008] In a preferred embodiment, the device further includes a rotating wheel, a steel bar wound on the rotating wheel, and a motor for driving the rotating wheel to rotate to release or wind up the steel bar. The motor and the rotating wheel are both mounted on the fixed base. The free end of the steel bar is connected to the inner nozzle. The steel bar drives the inner nozzle to extend and retract, and the outer nozzle to slide.

[0009] In a preferred embodiment: a front elastic buckle is provided between the rear part of the inner nozzle and the front part of the outer nozzle, and a rear elastic buckle is provided between the rear part of the outer nozzle and the fixed base. The engagement force of the front elastic buckle is less than that of the rear elastic buckle. During operation, the inner nozzle extends forward. After the front elastic buckle engages, the inner nozzle pulls the outer nozzle forward and separates the rear elastic buckle. During reset, the inner nozzle drives the outer nozzle to slide backward together. The front elastic buckle abuts against the rear elastic buckle between the outer nozzle and the fixed base and then separates. Then, the inner nozzle retracts the outer nozzle until it abuts against the outer nozzle. After that, the inner nozzle continues to push the outer nozzle backward and engages the rear elastic buckle.

[0010] In a preferred embodiment: a plug is provided at the rear end of the inner core tube, the plug is inserted into the outer spray pipe and engaged with the outer spray pipe, and the water inlet is located at the part where the plug is not inserted into the outer spray pipe.

[0011] In a preferred embodiment: the water inlet of the inner core tube is located on the side of the inner core tube, and the system also includes an external water inlet pipe, which is located on the side of the fixed base, and one end of the external water inlet pipe is connected to the water inlet.

[0012] In a preferred embodiment, a side cover is also included, which covers the gear and rack from the side, and the side cover is also provided with a receiving groove, in which the external water pipe is placed.

[0013] In a preferred embodiment: the water inlet is equipped with an adapter one, one end of the external water pipe is inserted into the adapter one, and the system also includes an adapter two, which is installed on the side cover, and the other end of the external water pipe is inserted into the adapter two.

[0014] In a preferred embodiment, the sealing ring is a Y-shaped sealing ring or a K-shaped sealing ring.

[0015] Compared with the prior art, this technical solution has the following advantages:

[0016] 1. An inner core tube is installed inside the outer nozzle. The inner nozzle is movably telescopically positioned between the inner core tube and the outer nozzle. The water outlet path connecting to the nozzle is formed by the combination of the inner cavity of the inner nozzle and the inner cavity of the inner core tube. Thus, water enters the inner cavity of the inner core tube from the inlet, then enters the inner cavity of the inner nozzle, and finally exits from the nozzle. Since the inner core tube and the outer nozzle are relatively fixed in position, only the inner nozzle moves telescopically relative to the outer nozzle and the inner core tube, except for the outer nozzle supporting the sliding of the inner nozzle and the inner core tube. The inner core tube structure is stable.

[0017] 2. A sealing ring is installed between the inner nozzle and the inner core tube to ensure the water outlet path is sealed between the inner core tube and the inner nozzle during operation. In particular, when using a Y-shaped sealing ring, not only is the sealing performance better, but it also facilitates the movement of the inner nozzle.

[0018] 3. The elastic stop pin of the inner nozzle can further drive the outer nozzle forward after the inner nozzle extends out of the outer nozzle, thereby increasing the working stroke of the cleaner. Moreover, the elastic stop pin facilitates the assembly of the inner nozzle.

[0019] 4. The plug at the end of the inner core tube is inserted and fixed to the outer spray pipe. The structure is simple and easy to assemble. The water inlet is set at the part where the plug is not inserted into the outer spray pipe, which can simplify the structure of the outer spray pipe and make water connection more convenient.

[0020] 5. The water inlet of the inner core tube is located on the side of the inner core tube. This allows the external water pipe to be placed more conveniently on the side of the fixed seat when connecting to the water inlet. In this way, the external water pipe does not occupy the space above the bidet, allowing the toilet to be made thinner. Moreover, it can avoid interference and friction between the external water pipe and other toilet components above the bidet, improving stability and service life.

[0021] 6. The external water inlet pipe is placed in the receiving groove of the side cover. Even if the external spray pipe pulls the external water inlet pipe when it moves back and forth, the external water inlet pipe can always be stably kept in the receiving groove. The external water inlet pipe is stable in position and the structure is solid. Attached Figure Description

[0034] Example 1

[0035] Please refer to Figures 1 to 9A smart toilet washer includes a fixed base 10, an outer spray pipe 20 reciprocatingly slidably disposed on the fixed base, and an inner spray pipe 30 reciprocatingly slidably disposed within the outer spray pipe. The front end of the inner spray pipe has a spray nozzle 32. It also includes an inner core tube 40, which is disposed within the outer spray pipe 20 and is fixed in position relative to the outer spray pipe, meaning the inner core tube and the outer spray pipe can reciprocate together. The inner spray pipe 30 is retractably sleeved outside the inner core tube 40, meaning the inner spray pipe is movably positioned between the outer spray pipe 20 and the inner core tube. A sealing ring 50 is provided between the inner spray pipe 30 and the inner core tube 40, the sealing ring being sleeved on the outer wall of the front end of the inner core tube 40. The inner cavity of the inner spray pipe communicates with the inner cavity of the inner core tube to form a water outlet path 60, which is connected to the spray nozzle 32. The rear end of the inner core tube has a water inlet 42 connected to the water outlet path. During operation, the inner spray pipe 30 extends forward beyond the outer spray pipe 20. The outer spray pipe can also slide forward along the fixed base 10 to a set position. External water enters the inner core pipe 40 through the water inlet 42, flows along the water outlet 60 to the front end of the inner spray pipe 30, and is then ejected from the spray nozzle 32 for cleaning. Since there is no hose for delivering water inside the outer spray pipe, the height of the rear end of the cleaner can be effectively reduced compared to existing structures, while also avoiding the risks of leakage and detachment caused by using hoses.

[0036] Understandably, the sliding of the outer nozzle 20 and the telescopic movement of the inner nozzle 30 can be achieved using existing methods, such as push rod drive, motor drive, hydraulic drive, or a combination of spring pull. Furthermore, there can be multiple nozzles, corresponding to multiple water outlet paths.

[0037] Preferably, the sealing ring 50 is a one-way sealing ring. More preferably, the sealing ring is a Y-shaped sealing ring, which can ensure the sealing of the water outlet channel 60 between the outer nozzle 20 and the inner nozzle 30 whether they are stationary or in relative motion. Of course, the sealing ring 50 can also be a two-way sealing ring, such as a K-shaped sealing ring.

[0038] Preferably, the inner nozzle 30 is provided with a resilient stop pin 34 at its rear end, and the inner wall of the outer nozzle 20 is provided with a locking step at its front. Figure 6 After the elastic stop pin moves forward with the inner nozzle and engages with the locking step, the inner nozzle can push the outer nozzle to slide forward together.

[0039] Preferably, the inner core tube 40 has a plug 44 at its rear end. The plug is inserted into the outer spray pipe 20 and engages with it. The water inlet 42 is located at the part where the plug is not inserted into the outer spray pipe. This makes it easier to connect water to the water inlet 42 and perform maintenance.

[0040] Preferably, the system further includes a meshing gear 72 and a rack 74. The gear is mounted on the fixed base 10, and the end of the rack is connected to the inner nozzle 30. Therefore, when the gear drives the rack to move, the rack moves, causing the inner nozzle to extend and retract, and the outer nozzle 20 to slide. That is, during operation, the gear 72 is activated, and the rack 74 extends, driving the inner nozzle 30 to extend forward beyond the outer nozzle 20. When the inner nozzle and outer nozzle engage (the elastic stop pin 34 engages with the locking step), the outer nozzle 20 slides forward on the fixed base 10 under the push of the inner nozzle 30. The distance the outer nozzle slides forward on the fixed base 10 can also be controlled by the gear and rack, provided that it is within the maximum sliding stroke of the outer nozzle. During resetting, the rack also drives the inner and outer nozzles to retract step by step.

[0041] Preferably, the system further includes a motor 76 for driving the gear 72 to rotate, thereby causing the rack 74 to extend and retract. The motor is mounted on the side of the fixed base 10. Understandably, the rotation of the gear can also be driven by the force of the water flow. Alternatively, the gear and rack structure can be replaced by a wheel and steel bar. For example, a motor drives the wheel to rotate, and the steel bar is wound around the wheel. The rotation of the motor causes the steel bar to release or rewind. The free end of the steel bar is connected to the inner nozzle, and the steel bar causes the inner nozzle to extend and retract, as well as the outer nozzle to slide.

[0042] Preferably, the water inlet 42 of the inner core tube 40 is located on the side of the inner core tube, and it also includes an external water inlet pipe 80, which is located on the side of the fixed base 10, with one end connected to the water inlet. In this embodiment, the external water inlet pipe 80 and the motor 76 are respectively located on the left and right sides of the fixed base 10. Since the external water inlet pipe 80 is located on the side of the fixed base 10, the height of the cleaner mainly depends on the height of the fixed base 10, and the overall height is not affected by the external water inlet pipe. In this embodiment, there are two spray nozzles, and two corresponding water outlet paths are provided, as are two corresponding external water inlet pipes.

[0043] Preferably, it also includes a side cover 90, which covers the gear 72 and rack 74 from the side, and the side cover is provided with a receiving groove 92, in which the external water pipe 80 is placed.

[0044] Preferably, the water inlet 42 is equipped with an adapter 46, one end of the external water pipe 80 is inserted into the adapter 46, and the system also includes an adapter 94, which is mounted on the side cover 90, and the other end of the external water pipe 80 is inserted into the adapter 94. Thus, as long as the external water source is connected to the adapter 94, the cleaner should be able to output water for cleaning.

[0045] Preferably, the system also includes a self-cleaning seat 100, which is installed at the front end of the external spray pipe 20. A self-cleaning water channel 101 is provided at the position where the self-cleaning seat extends forward from the external spray pipe, and the outlet of the self-cleaning water channel is located directly above the spray nozzle 32. Therefore, by opening the outlet of the self-cleaning water channel 101, water flow can self-clean the spray nozzle 32. Of course, if the spray nozzle is retracted into the external spray pipe in a stationary state, it can also perform self-cleaning during its outward extension. Understandably, during installation and use, the external water source is opened and closed via a switching valve 110. The switching valve is connected to the external water inlet pipe 80 and the self-cleaning water channel 101 via flexible hoses, thus controlling either self-cleaning or water output from the spray nozzle 32.

[0046] Example 2

[0047] Please refer to Figure 10 and Figure 11 The structure of the intelligent toilet washer has been modified, differing from the first embodiment in that the locking structure between the inner and outer spray pipes is different. The elastic stop pin and locking step structure have been eliminated. Specifically, a front elastic buckle 120 is provided between the rear of the inner spray pipe 30 and the front of the outer spray pipe 20, and a rear elastic buckle 130 is provided between the rear of the outer spray pipe 20 and the fixed base 10. The binding force of the front elastic buckle 120 is less than that of the rear elastic buckle 130. Thus, in operation, initially, the front elastic buckle 120 is disengaged and the rear elastic buckle 130 is engaged. Driven by the motor, the inner spray pipe 30 first extends forward relative to the outer spray pipe 20. Then, after the front elastic buckle 120 is engaged, the inner spray pipe 30 pulls the outer spray pipe 20 forward and separates the rear elastic buckle 130, allowing the outer spray pipe 30 to slide forward along the fixed base 10. During reset, due to the engagement of the front elastic latch 120, the inner nozzle 30 first drives the outer nozzle 20 to slide backward together. Then, the front elastic latch 120 abuts against the rear elastic latch 130 between the outer nozzle and the fixed seat and separates. Next, the inner nozzle 30 retracts the outer nozzle 20 until it abuts against the outer nozzle. After that, the inner nozzle 30 continues to push the outer nozzle 20 backward to slide backward and engage the rear elastic latch 130.

[0048] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
