Description

Technical Field

[0001] This invention belongs to the field of cleaning device technology and relates to a cleaning device. Background Technology

[0002] The existing smart toilets mainly use a bidet to perform the cleaning function. This bidet has multiple cleaning functions. When not in use, it is hidden inside the toilet. When in use, the bidet head extends and has functions such as posterior washing and feminine washing. Therefore, multiple water outlets need to be set on the bidet head, and each water outlet is connected to a corresponding water pipe to perform different cleaning functions.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN207130845U] discloses a curved pipe cleaner, including a cleaner bracket, a drive assembly, a distribution assembly, and a connection assembly. The drive assembly and the distribution assembly are connected and fixed to the cleaner bracket. The cleaner bracket is provided with a curved nozzle, a curved pipe sleeve, a bracket sliding cover, and a nozzle head. The curved nozzle, the curved pipe sleeve, and the bracket sliding cover are installed sequentially from the inside to the outside. The bracket sliding cover is fixedly connected to the cleaner bracket, and the curved nozzle is fixedly fitted to the nozzle head. The drive assembly drives the curved nozzle to reciprocate. The distribution assembly includes a distributor housing, a distributor motor, and a distributor pipe head. The distributor motor... The connector is fixedly connected to the distributor head. The connecting assembly includes several connecting hoses. The distributor head is provided with a nozzle cleaning interface, a buttock cleaning interface, and a feminine cleaning interface. The buttock cleaning interface and the feminine cleaning interface are respectively connected to the nozzle head through connecting hoses. The nozzle cleaning interface is connected to the nozzle cleaning inlet on the bracket sliding cover through connecting hoses. The nozzle cleaning inlet extends into the bracket sliding cover and is provided with a nozzle cleaning outlet. The nozzle head is provided with a first water outlet and a second water outlet corresponding to the buttock cleaning interface and the feminine cleaning interface, respectively. The curved nozzle and the curved pipe sleeve are provided with a third water outlet and a fourth water outlet at the end opposite to the nozzle head.

[0004] In the above structure, to achieve the multi-functional water spraying effect, a distributor and several connecting hoses are used. When cleaning, bending the spray nozzle requires moving the connecting hoses together, resulting in a relatively long connecting hose. To prevent the connecting hoses from kinking, a spring support sleeve is usually fitted onto the connecting hoses. This allows the connecting hoses to move easily while preventing kinking. However, using multiple connecting hoses increases the required installation space, making the installation space larger. Since the installation space inside the toilet is compact, the connecting hoses may come into contact with other parts when moving, thus affecting the normal use of the washer. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cleaner. The technical problem to be solved by this invention is: how to make the cleaner compact in structure while achieving multi-functional rinsing.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A cleaner includes a housing and a rinsing water pipe disposed within the housing. An inlet communicating with the rinsing water pipe is provided on one side of the housing. A driving component is fixedly connected to the housing. The driving shaft of the driving component is connected to the rinsing water pipe and drives the rinsing water pipe to move back and forth. The rinsing water pipe has a rinsing sleeve fitted at its outlet end, multiple outlets at its outlet end, a rinsing port on the rinsing sleeve, a limiting pin on the rinsing water pipe, and an elongated limiting hole on the rinsing sleeve along the moving direction of the rinsing water pipe. The limiting pin is embedded in the limiting hole and slides along the limiting hole, allowing any outlet to align and communicate with the rinsing port. The limiting pin abuts against the walls of the limiting hole at both ends. The housing has an elastic positioning component for positioning the rinsing sleeve partially extending outside the housing; the elastic positioning component releases its positioning when the rinsing sleeve retracts.

[0008] During cleaning, the drive unit moves the flushing water pipe forward. When the flushing water pipe moves to the point where the limiting pin abuts against the wall of the limiting hole, it drives the flushing sleeve to move synchronously. The flushing water pipe and the flushing sleeve move synchronously to the point where the elastic positioning element on the housing positions the flushing sleeve. At this time, the flushing sleeve extends out of the housing. According to the flushing requirements, the drive unit is activated again to move the flushing water pipe, so that the corresponding water outlet on the flushing water pipe is aligned with and connected to the flushing port. The external water pump delivers tap water of the corresponding pressure through the flushing water pipe from the flushing port to achieve the flushing function. During the movement, the limiting pin on the flushing water pipe slides in the limiting hole, while the flushing sleeve does not move due to the positioning of the elastic positioning element, thus achieving rapid flushing. When the flushing is completed, the flushing water pipe moves relative to the flushing sleeve until the limiting pin abuts against the wall of the rear end of the limiting hole, which drives the flushing sleeve to retract synchronously. During the retraction, the elastic positioning element releases the positioning of the flushing sleeve, so that the flushing sleeve and the flushing water pipe retract synchronously into the housing.

[0009] The above structure uses only one flushing water pipe and the relative displacement of the flushing sleeve to meet the multi-functional flushing needs of the cleaner. The use of only one flushing water pipe reduces the overall size of the cleaner and makes installation more convenient. Furthermore, the combination of the flushing water pipe, the flushing sleeve, and the elastic positioning component allows for synchronous and relative movement of both components with only one drive component, making control simpler and more convenient. This results in a more compact structure while achieving multi-functional cleaning.

[0010] In the aforementioned cleaner, a limiting bottom shell is connected to the flushing water pipe, and the limiting bottom shell has the aforementioned limiting pin on its outer side wall. The flushing sleeve is fitted onto the limiting bottom shell, and the limiting pin is embedded in the limiting hole.

[0011] Since the flushing water pipe is a silicone hose, the connection of the limiting bottom shell to the flushing water pipe facilitates the forming of the limiting pin, without changing the existing structure of the flushing water pipe. This makes it easy to install and remove, and also protects the flushing water pipe. It ensures the multi-functional cleaning function of the cleaner while achieving a compact structure.

[0012] In the aforementioned cleaner, the elastic positioning element is an elastic pin connected to the top of the housing. The rear end of the flushing sleeve is provided with a positioning hole into which the elastic pin can be inserted. The flushing sleeve is provided with a limiting plate below the positioning hole. The front end of the limiting plate is a guide part, and the rear end is a backing part. The guide part is inclined from top to bottom and rearward, and the lower end of the elastic pin can slide along the guide part. The backing part is arranged vertically and can abut against the outer wall of the elastic pin.

[0013] When the flushing sleeve moves forward until the elastic pin is embedded in the positioning hole, the elastic pin abuts against the abutment, preventing the flushing sleeve from moving forward. After flushing is completed, when the flushing sleeve moves backward synchronously with the flushing water pipe, the elastic pin slides out of the positioning hole along the guide, thereby releasing the positioning between the housing and the flushing sleeve. This allows the flushing sleeve and the flushing water pipe to retract synchronously into the housing, achieving stable use of the cleaner. Moreover, the addition of an elastic pin to the housing, a positioning hole on the flushing sleeve, and a limit plate does not increase the overall installation space. While ensuring the compact structure of the cleaner, it also enables the normal use of the multi-functional cleaning function.

[0014] Elastic positioning components can also be components such as elastic plungers.

[0015] In the aforementioned cleaner, the limiting plate is U-shaped and integrally formed with the rinsing sleeve. The guide portion and the abutment portion of the limiting plate are both connected to the wall of the positioning hole.

[0016] The limiting plate and the flushing sleeve are integrally molded, making installation easier. The guide part and the abutment part are connected to the hole wall of the positioning hole, which facilitates the insertion and removal of the elastic pin. This reduces the overall installation space required. Furthermore, the setting of the limiting plate ensures that the elastic pin will not hit the flushing water pipe after insertion, thus ensuring the normal use of the multi-functional cleaning device.

[0017] In the aforementioned cleaner, the water outlet of the rinsing pipe has a plate-shaped water outlet head, the water outlet is opened on the water outlet head, the upper part of the water outlet head protrudes upward to form a stop protrusion, the front end of the rinsing sleeve has a water outlet plate set on the water outlet head, the water outlet plate has multiple stop openings, when the stop protrusion is embedded in one of the stop openings, the corresponding water outlet is aligned with and connected to the rinsing port.

[0018] The raised baffle provides a certain level of positioning resistance when the corresponding water outlet and rinsing port are aligned, resulting in better positioning. Even if there is a slight error in the drive unit when moving the rinsing water pipe, the baffle and baffle can work together to limit the movement, further ensuring the normal operation of the multi-functional cleaner.

[0019] In the aforementioned cleaner, the front and rear sides of the gear shift protrusion have guide surfaces that are close together at their upper ends and inclined, and the front and rear sides of the gear shift opening have guide opening walls that fit with the guide surfaces.

[0020] The cooperation between the guide surface and the guide port wall allows the baffle protrusion to move stably out of the baffle port and quickly embed into the guide port wall when the drive component moves the flushing water pipe. This not only ensures stable water output from the cleaner baffle but also facilitates baffle adjustment.

[0021] In the aforementioned cleaner, each outlet of the water head is equipped with a sealing ring, and when the baffle protrusion is embedded in one of the baffle openings, the upper end of the sealing ring abuts against the water outlet plate.

[0022] The sealing ring ensures a tight seal when the water outlet and the rinsing port are aligned. Due to the protruding baffle, the upper end of the sealing ring does not contact the water outlet plate when the rinsing water pipe moves, thus not affecting the relative movement of the water outlet head and the water outlet plate. When the protruding baffle is embedded in one of the baffle ports, the sealing ring abuts against the water outlet plate to improve the seal, thereby ensuring the water output effect of the cleaner.

[0023] In the aforementioned cleaner, the left and right outer edges of the water outlet plate are folded down to form mounting flanges, the water outlet head is slidably disposed within the mounting flanges, the front end of the water outlet plate is folded down to form a travel limiting flange, and the front end of the water outlet head can abut against the travel limiting flange.

[0024] The installation of the flanged design guides the sliding of the water outlet head, while the travel limit flanged design prevents the water outlet head from excessively extending beyond the water outlet plate when moving in the front-to-back direction, thus improving the stability and safety of the cleaner.

[0025] In the aforementioned cleaner, the opening of the limiting bottom shell faces upward, the flushing sleeve is bent and its opening faces downward, the flushing sleeve is snapped onto the limiting bottom shell and forms a bent tube shape, and the flushing water pipe is located between the flushing sleeve and the limiting bottom shell.

[0026] The locking mechanism between the bottom shell and the flushing sleeve makes the entire flushing structure easier to install and also protects the outlet of the flushing water pipe, thus improving the stability of the flushing process.

[0027] In the aforementioned cleaner, the driving component is a drive motor disposed outside the housing, a drive gear is connected to the motor shaft of the drive motor, and a bent rack is connected to the rear end of the limiting bottom housing, the rack meshing with the drive gear.

[0028] By using a combination of drive gears and racks, the driving accuracy is improved while reducing the space occupied by the drive flushing water pipe.

[0029] Compared with existing technologies, this cleaner has the following advantages:

[0030] 1. By using only one flushing water pipe and coordinating the relative displacement of the flushing sleeve, the multi-functional flushing needs of the cleaner are met. Furthermore, the use of only one flushing water pipe reduces the overall size of the cleaner and makes installation more convenient. Moreover, through the cooperation of the flushing water pipe, the flushing sleeve, and the elastic positioning component, only one drive component is needed to achieve synchronous and relative movement of both components, making control simpler and more convenient. Thus, the cleaner achieves multi-functional cleaning while maintaining a more compact structure.

[0031] 2. When the flushing sleeve moves forward until the elastic pin is embedded in the positioning hole, the elastic pin abuts against the abutment, preventing the flushing sleeve from moving forward. After flushing is completed, when the flushing sleeve moves backward synchronously with the flushing water pipe, the elastic pin slides out of the positioning hole along the guide, thereby releasing the positioning between the housing and the flushing sleeve. This allows the flushing sleeve and the flushing water pipe to retract synchronously into the housing, achieving stable use of the cleaner. Moreover, the addition of an elastic pin to the housing, a positioning hole to the flushing sleeve, and a limit plate does not increase the overall installation space. This ensures the cleaner's compact structure while enabling normal use. Attached Figure Description

Detailed Implementation

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 3 As shown, this cleaner includes a housing 1 and a rinsing water pipe 2 disposed inside the housing 1. A water inlet 11 communicating with the rinsing water pipe 2 is provided on one side of the housing 1. A driving component 3 is fixedly connected to the housing 1. The driving shaft of the driving component 3 is connected to the rinsing water pipe 2 and drives the rinsing water pipe 2 to move back and forth.

[0044] Specifically, such as Figure 3-6As shown, the outlet end 21 of the flushing water pipe 2 is fitted with a flushing sleeve 4. The outlet end 21 of the flushing water pipe 2 has multiple outlets 22. The flushing sleeve 4 has a flushing port 41. The flushing water pipe 2 is provided with a limit pin 23. The flushing sleeve 4 has a long strip-shaped limit hole 42 along the moving direction of the flushing water pipe 2. The limit pin 23 is embedded in the limit hole 42 and slides along the limit hole 42 so that any outlet 22 is aligned with the flushing port 41 and connected. The limit pin 23 can abut against the hole walls at both ends of the limit hole 42. The housing 1 is provided with an elastic positioning member 5 for positioning the flushing sleeve 4 that extends out of the housing 1. When the flushing sleeve 4 retracts, the elastic positioning member 5 can release the positioning.

[0045] During cleaning, the drive unit 3 drives the flushing water pipe 2 to move forward. When the flushing water pipe 2 moves to the point where the limiting pin 23 abuts against the wall of the limiting hole 42, it drives the flushing sleeve 4 to move synchronously. The flushing water pipe 2 and the flushing sleeve 4 move synchronously to the point where the elastic positioning member 5 on the housing 1 positions the flushing sleeve 4. At this time, part of the flushing sleeve 4 extends out of the housing 1. According to the flushing requirements, the drive unit 3 is activated again to drive the flushing water pipe 2 to move, so that the corresponding water outlet 22 on the flushing water pipe 2 is aligned and connected with the flushing port 41. An external water pump delivers tap water of the corresponding pressure. The flushing water flows out from the flushing port 41 through the flushing pipe 2 to achieve the flushing function. When moving, the limiting pin 23 on the flushing water pipe 2 slides in the limiting hole 42, while the flushing sleeve 4 does not move due to the positioning of the elastic positioning member 5, thus achieving rapid flushing. When the flushing is completed, the flushing water pipe 2 moves relative to the flushing sleeve 4 until the limiting pin 23 abuts against the hole wall at the rear end of the limiting hole 42, which drives the flushing sleeve 4 to retract synchronously. When retracting, the elastic positioning member 5 releases the positioning of the flushing sleeve 4, so that the flushing sleeve 4 and the flushing water pipe 2 retract synchronously into the housing 1.

[0046] The above structure uses only one flushing water pipe 2, and with the relative displacement of the flushing sleeve 4, it realizes the multi-functional flushing needs of the cleaner. Moreover, by using only one flushing water pipe 2, the overall size of the cleaner is reduced and the installation is more convenient. Furthermore, through the cooperation of the flushing water pipe 2, the flushing sleeve 4 and the elastic positioning component 5, only one driving component 3 is needed to achieve synchronous and relative movement of the two, making the control simpler and more convenient. Thus, the structure is more compact while realizing the multi-functional cleaning of the cleaner.

[0047] like Figure 6 As shown, a limiting bottom shell 24 is connected to the flushing water pipe 2. The limiting bottom shell 24 has the aforementioned limiting pin 23 on its outer side wall. The flushing sleeve 4 is fitted onto the limiting bottom shell 24 and the limiting pin 23 is embedded in the limiting hole 42.

[0048] like Figure 3 and Figure 5As shown, the elastic positioning element 5 is an elastic pin 51 connected to the top of the housing 1. The rear end of the flushing sleeve 4 is provided with a positioning hole 43 for the elastic pin 51 to be inserted. The flushing sleeve 4 is provided with a limiting plate 44 below the positioning hole 43. The front end of the limiting plate 44 is a guide part 44a and the rear end is abutting part 44b. The guide part 44a is inclined from top to bottom and rearward, and the lower end of the elastic pin 51 can slide along the guide part 44a. The abutting part 44b is arranged vertically and can abut against the outer wall of the elastic pin 51. The limiting plate 44 is U-shaped and integrally formed with the flushing sleeve 4. The guide part 44a and the abutting part 44b of the limiting plate 44 are both connected to the hole wall of the positioning hole 43.

[0049] like Figure 4 and Figure 7 As shown, the outlet end 21 of the flushing water pipe 2 has a plate-shaped water outlet head 25, and a water outlet 22 is opened on the water outlet head 25. The upper part of the water outlet head 25 protrudes upward to form a stop protrusion 25a. The front end of the flushing sleeve 4 has a water outlet plate 45 set on the water outlet head 25. The water outlet plate 45 has multiple stop holes 45a. When the stop protrusion 25a is inserted into one of the stop holes 45a, the corresponding water outlet 22 is aligned and connected with the flushing port 41. The front and rear sides of the stop protrusion 25a have guide surfaces 25b that are close together at the top and inclined. The front and rear sides of the stop port 45a have guide port walls 45b that fit with the guide surface 25b. The water outlet head 25 is provided with a sealing ring 6 at each water outlet 22. When the stop protrusion 25a is embedded in one of the stop ports, the upper end of the sealing ring 6 abuts against the water outlet plate 45. The left and right outer edges of the water outlet plate 45 are folded down to form mounting flanges 45c. The water outlet head 25 is slidably disposed in the mounting flanges 45c. The front end of the water outlet plate 45 is folded down to form a travel limit flange 45d. The front end of the water outlet head 25 can abut against the travel limit flange 45d.

[0050] like Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the opening of the limiting bottom shell 24 faces upward, the flushing sleeve 4 is bent and the opening faces downward, the flushing sleeve 4 is snapped onto the limiting bottom shell 24 and forms a bent tube shape, the flushing water pipe 2 is located between the flushing sleeve 4 and the limiting bottom shell 24, the driving component 3 is a drive motor set outside the housing 1, the drive motor shaft is connected to the drive gear 31, the rear end of the limiting bottom shell 24 is connected to a bent rack 7, the rack 7 meshes with the drive gear 31.
