Description

Technical Field

[0001] The utility model relates to an intelligent toilet cleaner, in particular to an intelligent toilet cleaner without a built-in hose. Background Art

[0002] With the rapid development of smart toilets, ultra-thin smart toilets are becoming increasingly popular among consumers. The rear end space of smart toilets is shrinking (in both height and length). Existing single-stage telescopic cleaners are no longer able to meet the product's space requirements. Multi-stage telescopic (i.e., two-stage telescopic) cleaners can partially address these space requirements. A two-stage telescopic cleaner incorporates an inner nozzle within an outer nozzle. The inner nozzle can extend outward relative to the outer nozzle and then connect to the inner nozzle via a flexible connecting tube to form a water supply path. However, when operating, existing two-stage telescopic cleaners require the inner and outer nozzles to retract and extend back and forth. This means the inner nozzle repeatedly retracts and retracts relative to the outer nozzle, while the flexible connecting tube (which delivers water to the inner nozzle) extends into the outer nozzle and moves back and forth with it. This movement of the inner nozzle causes the flexible connecting tube to constantly scrape against the outer nozzle, potentially causing the flexible connecting tube to leak or even fall off. This leaves room for improvement in the product's stability and service life. Utility Model Content

[0003] The utility model provides an intelligent toilet cleaner that eliminates the flexible connecting pipe to avoid the phenomenon of water leakage and falling off of the flexible connecting pipe, which overcomes the shortcomings of the background technology. The technical solution adopted by the utility model to solve the technical problem is:

[0004] A smart toilet cleaner comprises a fixed seat, an outer nozzle arranged reciprocatingly on the fixed seat, an inner nozzle arranged reciprocatingly in the outer nozzle, a water nozzle being provided at the front end of the inner nozzle, and an inner core tube being provided. The inner core tube is arranged in the outer nozzle and is relatively fixed in position with the outer nozzle, the inner nozzle can be telescopically sleeved on the outside of the inner core tube, a sealing ring is provided between the inner nozzle and the inner core tube, the sealing ring is sleeved on the outer wall of the front end of the inner core tube, the inner cavity of the inner nozzle is connected to the inner cavity of the inner core tube to form a water outlet waterway, the water outlet waterway is connected to the water nozzle, and the rear end of the inner core tube is provided with a water inlet connected to the water outlet waterway.

[0005] In a preferred embodiment: the inner nozzle is provided with an elastic stop pin at the rear end, and the inner wall of the outer nozzle is provided with a locking step at the front. 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: it also includes a meshing gear and rack, the gear is set on the fixed seat, the end of the rack is connected to the inner nozzle, and when the rack moves, it drives the inner nozzle to extend and retract and the outer nozzle to slide.

[0007] In a preferred embodiment, it also includes a motor for driving the gear to rotate to drive the rack to move telescopically, and the motor is installed on the side of the fixing base.

[0008] In a preferred embodiment: it also 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 roll up the steel bar. The motor and the rotating wheel are both installed on the fixed seat. 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 clip that fits together with each other is provided between the rear portion of the inner nozzle and the front portion of the outer nozzle, and a rear elastic clip that fits together with each other is provided between the rear portion of the outer nozzle and the fixing seat, the binding force of the front elastic clip is smaller than the binding force of the rear elastic clip. During operation, the inner nozzle extends forward, and after the front elastic clip is engaged, the inner nozzle pulls the outer nozzle forward and separates the rear elastic clip. During reset, the inner nozzle drives the outer nozzle to slide backward together, and the front elastic clip separates after abutting against the rear elastic clip between the outer nozzle and the fixing seat. Then the inner nozzle retracts the outer nozzle until it abuts against the outer nozzle, and then the inner nozzle continues to push the outer nozzle backward and engages the rear elastic clip.

[0010] In a preferred embodiment: a plug is provided at the rear end of the inner core tube, the plug is partially inserted into the outer nozzle and is clamped with the outer nozzle, and the water inlet is arranged at a portion where the plug is not inserted into the outer nozzle.

[0011] In a preferred embodiment: the water inlet of the inner core tube is arranged on the side of the inner core tube, and further comprises an external water diversion pipe, the external water diversion pipe is arranged on the side of the fixing seat, and one end of the external water diversion pipe is connected to the water inlet.

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

[0013] In a preferred embodiment: the water inlet is equipped with an adapter 1, one end of the external water diversion pipe is plugged into the adapter 1, and also includes an adapter 2, the adapter 2 is installed on the side cover, and the other end of the external water diversion pipe is plugged into the adapter 2.

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

[0015] Compared with the background technology, this technical solution has the following advantages:

[0016] 1. An inner core tube is disposed within the outer nozzle, and the inner core tube is movably and telescopically disposed between the inner core tube and the outer nozzle. The outlet waterway connected to the water nozzle is formed by the inner cavity of the inner nozzle tube and the inner cavity of the inner core tube. Thus, water flows from the water inlet of the inner core tube into the inner cavity of the inner core tube, then into the inner cavity of the inner nozzle tube, and is ultimately ejected from the water nozzle. Because the inner core tube and the outer nozzle are relatively fixed in position, only the inner nozzle tube moves telescopically relative to the outer nozzle tube and the inner core tube, except when the outer nozzle supports the inner nozzle tube and slides with the inner core tube, resulting in a stable inner core tube structure.

[0017] 2. A sealing ring is provided between the inner nozzle and the inner core tube to ensure the sealing of the water outlet channel between the inner core tube and the inner nozzle during operation. Especially when a Y-shaped sealing ring is used, it not only has better sealing performance but is also more conducive to the movement of the inner nozzle.

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

[0019] 4. The plug at the end of the inner core tube is plugged and fixed to the outer nozzle, with a simple structure and easy assembly. The water inlet is set at the position where the plug is not inserted into the outer nozzle, which can simplify the structure of the outer nozzle and make water connection more convenient.

[0020] 5. The water inlet of the inner core tube is arranged on the side of the inner core tube, so that the external water diversion pipe can be more conveniently placed on the side of the fixed seat when docking with the water inlet. In this way, the external water diversion pipe does not occupy the space above the washer, which can make the toilet thinner. Moreover, it can avoid interference and friction between the external water diversion pipe and other toilet components above the washer, thereby improving stability and service life.

[0021] 6. The external water diversion pipe is placed in the receiving groove of the side cover. Even if the external nozzle pulls the external water diversion pipe when moving back and forth, the external water diversion pipe can always be stably maintained in the receiving groove. The position of the external water diversion pipe is stable and the structure is firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1

[0035] Please refer to Figures 1 to 9The intelligent toilet cleaner includes a fixed base 10, an outer nozzle 20 reciprocatingly mounted on the fixed base, and an inner nozzle 30 reciprocatingly mounted within the outer nozzle. The inner nozzle has a water nozzle 32 at its front end. The device also includes an inner core tube 40, which is mounted within the outer nozzle 20 and fixed relative to the outer nozzle, so that the inner core tube and the outer nozzle can reciprocate together. The inner nozzle 30 is telescopically mounted outside the inner core tube 40, so that the inner nozzle is movably positioned between the outer nozzle 20 and the inner core tube. A sealing ring 50 is provided between the inner nozzle 30 and the inner core tube 40. The sealing ring is mounted on the outer wall of the front end of the inner core tube 40. The inner cavity of the inner nozzle is connected to the inner cavity of the inner core tube to form a water outlet waterway 60. The water outlet waterway is connected to the water nozzle 32. The rear end of the inner core tube is provided with a water inlet 42 connected to the water outlet waterway. During operation, the inner nozzle 30 extends forward from the outer nozzle 20. The outer nozzle also slides forward along the fixed base 10 to a set position. External water enters the inner core tube 40 through the water inlet 42, flows along the water outlet 60 to the front end of the inner nozzle 30, and is then ejected from the water nozzle 32 to perform the cleaning operation. Because the outer nozzle does not contain a hose to transport water, the height of the rear end of the washer can be effectively reduced compared to existing structures, and the hidden dangers of water leakage and detachment caused by the use of a hose are also avoided.

[0036] It is understood that the sliding of the outer nozzle 20 and the telescopic movement of the inner nozzle 30 can be achieved by existing methods, such as push rod drive, motor drive, hydraulic drive, or spring pull. In addition, there can be multiple water nozzles, and corresponding water outlet waterways are also multiple.

[0037] Preferably, the sealing ring 50 is a one-way sealing ring. More preferably, the sealing ring is a Y-shaped sealing ring. The Y-shaped sealing ring can ensure the sealing of the water outlet channel 60 whether the outer nozzle 20 and the inner nozzle 30 are in a stationary state or in a state of relative movement. 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 an elastic stop pin 34 at the rear end, and the inner wall of the outer nozzle 20 is provided with a locking step at the 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, a plug 44 is provided at the rear end of the inner core tube 40, which is partially inserted into the outer nozzle 20 and engaged with the outer nozzle, and the water inlet 42 is provided at the portion where the plug is not inserted into the outer nozzle. This makes it easier to connect water to and inspect the water inlet 42.

[0040] Preferably, the device 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 drives 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 from the outer nozzle 20. When the inner and outer nozzles engage (the elastic stop pin 34 engages 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, of course, provided that it is within the maximum sliding travel of the outer nozzle. During reset, the rack also drives the inner and outer nozzles to retract step by step.

[0041] Preferably, the apparatus further includes a motor 76 for driving the gear 72 to rotate and thereby drive the rack 74 to extend and retract. The motor is mounted on the side of the fixed base 10. It is understood that the rotation of the gear can also be driven by the force of the water flow. Furthermore, the gear and rack structure can be replaced by a rotating wheel and steel bars. For example, a motor drives the rotating wheel to rotate, and a steel bar is wound around the rotating wheel. The rotation of the motor drives the steel bar to release or reel. The free end of the steel bar is connected to the inner nozzle, and the steel bar drives the inner nozzle to extend and retract, and the outer nozzle to slide.

[0042] Preferably, the water inlet 42 of the inner core tube 40 is arranged on the side of the inner core tube, and further includes an external water diversion pipe 80, which is arranged on the side of the fixing seat 10, and one end of the external water diversion pipe is connected to the water inlet. In this embodiment, the external water diversion pipe 80 and the motor 76 are respectively arranged on the left and right sides of the fixing seat 10. The external water diversion pipe 80 is arranged on the side of the fixing seat 10, and the height of the cleaning device mainly depends on the height of the fixing seat 10, and the overall height is not affected by the external water diversion pipe. In this embodiment, the number of water nozzles is two, and two water outlet waterways are correspondingly provided. Similarly, two external water diversion pipes are also correspondingly provided.

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

[0044] Preferably, the water inlet 42 is equipped with an adapter 1 46, one end of the external water pipe 80 is plugged into the adapter 1 46, and further includes an adapter 2 94, which is mounted on the side cover 90, and the other end of the external water pipe 80 is plugged into the adapter 2 94. In this way, as long as the external water source is connected to the adapter 2 94, the washer should be able to discharge water for cleaning.

[0045] Preferably, a self-cleaning seat 100 is further included, and the self-cleaning seat is installed at the front end of the outer nozzle 20. A self-cleaning water channel 101 is provided at the position where the self-cleaning seat extends forward from the outer nozzle, and the water outlet of the self-cleaning water channel is located directly above the water nozzle 32. Therefore, by opening the water outlet of the self-cleaning water channel 101, the water flow can self-clean the water nozzle 32. Of course, if the water nozzle is retracted into the outer nozzle in a stationary state, it can also be self-cleaned during the process of extending outward. It can be understood that when installed and used, the external water source is opened and closed by the switching valve 110, and the switching valve is connected to the external water pipe 80 and the self-cleaning water channel 101 respectively through a hose, so that the self-cleaning or water outlet of the water nozzle 32 can be controlled by the switching valve.

[0046] Example 2

[0047] Please refer to Figure 10 and Figure 11 The structure of the smart toilet cleaner has been deformed. It differs from the previous embodiment 1 in that the locking structure between the inner and outer nozzles is different, eliminating the elastic stop pin and locking step structure. Specifically, a front elastic buckle 120 is provided between the rear portion of the inner nozzle 30 and the front portion of the outer nozzle 20, and a rear elastic buckle 130 is provided between the rear portion of the outer nozzle 20 and the fixing base 10. The binding force of the front elastic buckle 120 is smaller than the binding force of the rear elastic buckle 130. Thus, during operation, in the initial state, the front elastic buckle 120 is separated and the rear elastic buckle 130 is engaged. Driven by the motor, the inner nozzle 30 first extends forward relative to the outer nozzle 20. Then, after the front elastic buckle 120 is engaged, the inner nozzle 30 pulls the outer nozzle 20 forward and separates the rear elastic buckle 130, causing the outer nozzle 30 to slide forward along the fixing base 10. During resetting, since the front elastic buckle 120 is engaged, the inner nozzle 30 first drives the outer nozzle 20 to slide backward together, then the front elastic buckle 120 abuts against the rear elastic buckle 130 between the outer nozzle and the fixing seat and separates, then the inner nozzle 30 retracts the outer nozzle 20 until it abuts against the outer nozzle, and then the inner nozzle 30 continues to push the outer nozzle 20 to slide backward and engages the rear elastic buckle 130.

[0048] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
