Description
Technical Field
[0001] The utility model relates to a spray washing device for a smart toilet, in particular to a spray washing device for a smart toilet with a hose placed on the side of a spray pipe. Background Art
[0002] With the rapid development of smart toilets, ultra-thin smart toilets are becoming more and more popular among consumers. The space at the rear end of the smart toilet is getting smaller (height and length), and the original first-stage telescopic spray washing device can no longer meet the space requirements of the product. A multi-stage telescopic (i.e., second-stage telescopic) spray washing device can solve some of the current space requirements. The second-stage telescopic spray washing device is to sleeved an inner spray pipe in the outer spray pipe. In addition to the outer spray pipe being telescopic, the inner spray pipe can also extend outward relative to the outer spray pipe. The water path between the switching valve and the inner spray pipe is connected by a silicone hose, that is, the hose is used to convey water source to the inner spray pipe. However, the special structure and installation method of the spray washing device with the front end lower and the rear end higher itself will cause its size in terms of height to be relatively large. Coupled with the hose being connected to the inner spray pipe at the rear end of the spray washing device, the hose further occupies the space above the rear end of the spray washing device, resulting in a still relatively large overall thickness of the spray washing device. At the same time, the hose also needs to cooperate with some components for use, such as a two-way pipe and a buckle for guiding and positioning. And the inner spray pipe and the outer spray pipe need to move back and forth during operation, so it is difficult to restrict the movement track of the hose, which requires an avoidance design to prevent the hose from interfering with other parts and affecting the normal operation of the spray washing device. There is even a possibility of scratching resulting in water leakage or detachment of the hose, making the product quality unable to be guaranteed for a long time. Content of the Utility Model
[0003] The utility model provides a spray washing device for a smart toilet with effectively reduced thickness and stable performance, which overcomes the deficiencies existing in the background art. The technical solution adopted by the utility model to solve its technical problems is as follows:
[0004] The spray washing device for a smart toilet includes a fixed seat, a telescopic spray pipe slidably arranged on the fixed seat, and a hose for introducing water into the telescopic spray pipe. An inlet is provided at the rear end of the telescopic spray pipe corresponding to the hose, a water spray nozzle is provided at the front end of the telescopic spray pipe, and a side cover connected to the side of the fixed seat is further included. A receiving groove is provided on the side cover, the hose is placed in the receiving groove, and the inlet of the telescopic spray pipe is located on the side of the telescopic spray pipe facing the side cover.
[0005] In a preferred embodiment: a first adapter is connected to the inlet, one end of the hose is inserted into the first adapter, a second adapter is further included, the second adapter is installed on the side cover, and the other end of the hose is inserted into the second adapter.
[0006] In a preferred embodiment: The hose is placed in a C shape in the vertical plane.
[0007] In a preferred embodiment: It further includes a meshing gear and rack. The gear is arranged on the fixed seat. The end of the rack is connected to the telescopic spray pipe. When the rack moves, it drives the telescopic spray pipe to slide back and forth. The side cover covers the gear and rack.
[0008] In a preferred embodiment: It further includes a motor for driving the rotation of the gear to drive the telescopic movement of the rack. The motor is installed on the side of the fixed seat. The motor and the side cover are respectively connected to the left and right sides of the fixed seat.
[0009] In a preferred embodiment: It further includes a runner, a steel bar wound on the runner, and a motor for driving the rotation of the runner to release or wind up the steel bar. The motor and the runner are both installed on the fixed seat. The free end of the steel bar is connected to the telescopic spray pipe, and the steel bar drives the telescopic spray pipe to slide.
[0010] In a preferred embodiment: The telescopic spray pipe includes an outer spray pipe, an inner core pipe arranged in the outer spray pipe and relatively fixed in position with the outer spray pipe, and an inner spray pipe slidably arranged in the outer spray pipe and sleeving the inner core pipe. A sealing ring is arranged between the inner spray pipe and the inner core pipe. The water spray nozzle is connected to the front end of the inner spray pipe. The water inlet is arranged at the rear end of the inner core pipe. The rack is connected to the inner spray pipe. When using the rack, the rack is connected to the inner spray pipe. When using the steel bar, the steel bar is connected to the inner spray pipe.
[0011] In a preferred embodiment: A plug is arranged at the rear end of the inner core pipe. The plug is partially inserted into the outer spray pipe and is snap-connected to the outer spray pipe. The water inlet is arranged at the part of the plug that is not inserted into the outer spray pipe.
[0012] In a preferred embodiment: The inner spray pipe is provided with an elastic retaining pin at the rear end. A clamping step is arranged on the inner wall of the front part of the outer spray pipe. After the elastic retaining pin moves forward with the inner spray pipe and is snap-connected to the clamping step, the inner spray pipe pushes the outer spray pipe to slide forward together.
[0013] In a preferred embodiment: There are front elastic buckles that are mutually adapted between the rear part of the inner spray pipe and the front part of the outer spray pipe, and rear elastic buckles that are mutually adapted between the rear part of the outer spray pipe and the fixed seat. The binding force of the front elastic buckles is less than that of the rear elastic buckles. During operation, the inner spray pipe extends forward. After the front elastic buckles are engaged, the inner spray pipe pulls the outer spray pipe forward and separates the rear elastic buckles. When resetting, the inner spray pipe drives the outer spray pipe to slide backward together. The front elastic buckles separate after abutting against the rear elastic buckles between the outer spray pipe and the fixed seat. Then the inner spray pipe retracts the outer spray pipe until it abuts against the outer spray pipe. After that, the inner spray pipe continues to push the outer spray pipe backward and engages the rear elastic buckles.
[0014] In a preferred embodiment: The telescopic spray pipe includes an outer spray pipe, an inner spray pipe that is reciprocally slidably arranged in the outer spray pipe, and an elastic member connected between the outer spray pipe and the inner spray pipe. When using a rack, the rack is connected to the outer spray pipe. When using a steel bar, the steel bar is connected to the outer spray pipe. The water spray nozzle is connected to the front end of the inner spray pipe. The water inlet is arranged at the rear end of the outer spray pipe. A baffle is axially movably sleeved at the rear end opening of the inner spray pipe. A sealing ring is sleeved at the rear end of the inner spray pipe. A shoulder is provided on the inner wall of the outer spray pipe near the front end. When water flows into the outer spray pipe, it pushes the baffle to close the opening at the rear end face of the inner spray pipe, and then pushes the inner spray pipe to slide forward and extend out of the outer spray pipe. When the sealing ring and the baffle press against the shoulder, the shoulder lifts the baffle to open the opening at the end face of the inner spray pipe. When the water flow is cut off, the elastic member drives the inner spray pipe to retract into the outer spray pipe.
[0015] In a preferred embodiment: The elastic member sleeves the inner spray pipe. An inner lip is provided at the front end opening position of the inner wall of the outer spray pipe, and the inner lip blocks the elastic member.
[0016] Compared with the background technology, this technical solution has the following advantages:
[0017] 1. The hose is located on the side of the fixed seat and the telescopic spray pipe and is placed in the accommodation groove of the side cover. The hose does not occupy the space above the telescopic spray pipe, especially the upper position at the rear end. In this way, the intelligent toilet spray device can be further thinned. Moreover, the hose is placed in the accommodation groove of the side cover. Even if it reciprocates, it can be well maintained in the accommodation groove, avoiding interference and friction with other components, and improving the stability and service life of the spray device.
[0018] 2. The two ends of the hose are respectively inserted into the first and second adapters, and the assembly is very convenient, and the hose is firmly connected.
[0019] 3. The hose is placed in a C shape, which is beneficial for expansion and contraction and can also avoid displacement during movement.
[0020] 4. The side cover not only houses the hose but also covers the rack and pinion, eliminating the need to increase the number of components of the flushing device and featuring a simple structure.
[0021] 5. The rack drives the inner spray pipe to extend forward relative to the outer spray pipe to achieve primary elongation, and then the entire telescopic spray pipe slides forward along the fixed seat for secondary elongation. Only when the outer spray pipe and the inner core pipe move forward can they drive the hose to move together. The moving stroke of the hose is small, and the whole is outside the telescopic spray pipe, ensuring a stable structure.
[0022] 6. The plug at the end of the inner core pipe is inserted and fixed to the outer spray pipe, with a simple structure and convenient assembly. 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.

[0036] Embodiment 1
[0037] Please refer to Figures 1 to 8 , an intelligent toilet washing device, including a fixed seat 10, a telescopic spray pipe 20 reciprocally and slidably arranged on the fixed seat, and a hose 30 for introducing water into the telescopic spray pipe. The rear end of the telescopic spray pipe is provided with a water inlet 21 corresponding to the hose, and the front end of the telescopic spray pipe is provided with a spray nozzle 22. During operation, the telescopic spray pipe 20 slides forward along the fixed seat 10, water flows into the telescopic spray pipe through the hose 30, and then is ejected outward from the spray nozzle 22 for cleaning. It further includes a side cover 40 connected to the side of the fixed seat 10, that is, the side of the fixed seat 10 is provided with a side cover 40. Therefore, the fixed seat 10 and the side cover 40 can be an integral part or a structure in which two elements are connected together. The side cover 40 is provided with a receiving groove 42, the hose 30 is placed in the receiving groove 42, and the water inlet 21 of the telescopic spray pipe 20 is located on the side of the telescopic spray pipe facing the side cover 40. Therefore, during operation, when the telescopic spray pipe 20 slides forward along the fixed seat 10, it pulls the hose 30 to deform, but the hose is stably held in the receiving groove 42, and the hose is on one side of the telescopic spray pipe 20 and the fixed seat 10. The height of the hose is lower than that of the telescopic spray pipe 20, and the hose does not increase the thickness of the washing device. Actually, the height of the vertex of the side cover 40 is also lower than the height of the vertex of the telescopic spray pipe 20
[0038] Preferably, a first adapter 23 is installed at the water inlet 21, one end of the hose 30 is inserted into the first adapter, and it further includes a second adapter 44, the second adapter 44 is installed on the side cover 40, and the other end of the hose is inserted into the second adapter. The flexible joint 23 is connected to the telescopic spray pipe 20, which can stably pull the hose 30 to deform, while the second adapter 44 is installed on the side cover 40, which can stably place the hose in the receiving groove 42
[0039] Preferably, the hose 30 is placed in a C shape in the vertical plane
[0040] Preferably, it further includes meshing gears 51 and a rack 52. The gear 51 is arranged on the fixed seat 10. The end of the rack 52 is connected to the telescopic nozzle 20. When the rack moves, it drives the telescopic nozzle to slide back and forth, and the side cover 40 covers the gear and the rack. During operation, driven by the gear and rack, the telescopic nozzle slides back and forth on the fixed seat. The rotation of the gear can be driven by electricity or by water. Further preferably, it further includes a motor 53 for driving the rotation of the gear 51 to drive the rack to expand and contract. The motor is installed on the side of the fixed seat 10, and the motor 53 and the side cover 40 are respectively connected to the left and right sides of the fixed seat 10.
[0041] Understandably, the rotation of the gear can also be driven by the impact force of water flow. In addition, the structure of the gear and the rack can also be replaced by a runner and a steel bar. For example, the motor drives the runner to rotate, and the steel bar is wound around the runner. When the motor rotates, it drives the steel bar to be released or wound up. The free end of the steel bar is connected to the telescopic nozzle, and the steel bar drives the telescopic nozzle to slide.
[0042] Preferably, the telescopic nozzle 20 includes an outer nozzle 20-1, an inner core tube 20-2 arranged inside the outer nozzle and relatively fixed in position with the outer nozzle, and an inner nozzle 20-3 slidably arranged in the outer nozzle and sleeving the inner core tube. A sealing ring 24 is arranged between the inner nozzle 20-3 and the inner core tube 20-2. The water spray nozzle 22 is connected to the front end of the inner nozzle 20-3, and the water inlet 21 is arranged at the rear end of the inner core tube 20-2. The rack 52 is connected to the inner core tube 20-2 (if the runner and steel bar method is used, the steel bar is connected to the inner nozzle). During operation, the motor 53 first drives the inner nozzle 20-3 to extend from the outer nozzle 20-1. After the inner nozzle is clamped with the outer nozzle, the outer nozzle 20-1 slides along the fixed seat 10. Water flows along the hose 30 and the water inlet 21 into the inner core tube 20-2, then into the inner nozzle 20-3, and finally flows out from the water spray nozzle 22.
[0043] Preferably, a plug is arranged at the rear end of the inner core tube 20-2. The plug is partially inserted into the outer nozzle 20-1 and clamped with the outer nozzle, and the water inlet 21 is arranged at the part of the plug that is not inserted into the outer nozzle.
[0044] Preferably, an elastic retaining pin is arranged at the rear end of the inner nozzle 20-3, and a clamping step is arranged on the inner wall of the front part of the outer nozzle 20-1. After the elastic retaining pin moves forward with the inner nozzle and is clamped with the clamping step, the inner nozzle pushes the outer nozzle to slide forward together. Of course, the relative expansion and contraction and limit between the inner nozzle and the outer nozzle can also adopt existing structures, or the structure Figure 9 and Figure 10As shown, a front elastic buckle 60 adapted to each other is provided between the rear part of the inner spray pipe 20-3 and the front part of the outer spray pipe 20-1, and a rear elastic buckle 70 adapted to each other is provided between the rear part of the outer spray pipe 20-1 and the fixed seat 10. The binding force of the front elastic buckle 60 is less than that of the rear elastic buckle 70. In this way, during operation, in the initial state, the front elastic buckle 60 is separated and the rear elastic buckle 70 is combined. Driven by the motor, the inner spray pipe 20-3 first extends forward relative to the outer spray pipe 20-1. Then, after the front elastic buckle 60 is combined, the inner spray pipe 20-3 pulls the outer spray pipe 20-1 forward and separates the rear elastic buckle 70, and the outer spray pipe 20-1 slides forward along the fixed seat 10. When resetting, since the front elastic buckle 60 is combined, the inner spray pipe 20-3 first drives the outer spray pipe 20-1 to slide backward together. Then, the front elastic buckle 60 is separated after abutting against the rear elastic buckle 170 between the outer spray pipe and the fixed seat. Then, the inner spray pipe 20-3 retracts the outer spray pipe 20-1 until it abuts against the outer spray pipe. After that, the inner spray pipe 20-3 continues to push the outer spray pipe 20-1 backward to slide backward and combines the rear elastic buckle 70.
[0045] Embodiment 2
[0046] Please refer to Figure 11 and Figure 12 In Embodiment 2, the difference from Embodiment 1 is that the structure of the telescopic spray pipe is also different. In this embodiment, the telescopic spray pipe includes an outer spray pipe 25a, an inner spray pipe 26a slidably arranged in the outer spray pipe reciprocally, and an elastic member 27a connected between the outer spray pipe and the inner spray pipe. The rack is connected to the outer spray pipe 25a. The water spray nozzle is connected to the front end of the inner spray pipe 26a. The water inlet 21a is arranged at the rear end of the outer spray pipe 25a. An axial movable baffle 28a is sleeved at the rear end opening of the inner spray pipe 26a. A sealing ring 29a is sleeved at the rear end of the inner spray pipe. A shoulder 251 is arranged on the inner wall of the outer spray pipe 25a near the front end. During operation, when water flows through the hose and the water inlet 21a into the outer spray pipe 25a, the water first pushes the baffle 28a to close the opening at the rear end face of the inner spray pipe 26a, that is, the baffle covers the inner spray pipe. Then, the water pushes the inner spray pipe 26a to slide forward and extend out of the outer spray pipe 25a. When the sealing ring 29a and the baffle 28a press against the shoulder 251, the shoulder 251 lifts the baffle 28a to open the opening at the end face of the inner spray pipe 26a, and the water flows into the inner spray pipe. When the water flow is cut off, the elastic member 27a drives the inner spray pipe 26a to retract into the outer spray pipe 25a. Since the rack is connected to the outer spray pipe 25a, the outer spray pipe or the telescopic spray pipe is driven by the rack to slide on the fixed seat 10.
[0047] Preferably, the elastic member 27a sleeves the inner spray pipe 26a, and an inner lip 252 is provided at the front end opening position on the inner wall of the outer spray pipe 25a, and the inner lip 252 blocks the elastic member 27a.
