Description

Technical Field

[0001] The invention belongs to the technical field of cleaners and relates to a cleaner. Background Art

[0002] The cleaning function of existing smart toilets is mainly achieved by a washer, which has a multifunctional cleaning function. When not in use, it is hidden in the toilet. When in use, the cleaning head is extended and has functions such as buttocks cleaning and female cleaning. Therefore, it is necessary to set multiple water outlets on the cleaning head, and each water outlet corresponds to a corresponding water pipe connection, so as to achieve cleaning with different functions.

[0003] For example, Chinese patent application [authorization announcement number: CN207130845U] discloses a curved pipe cleaner, including a cleaner bracket, a driving assembly, a distribution assembly and a connecting assembly. The driving assembly and the distribution assembly are connected and fixed on the cleaner bracket. The cleaner bracket is provided with a curved nozzle, a curved pipe sheath, a bracket slide cover and a nozzle head. The curved nozzle, the curved pipe sheath and the bracket slide cover are installed in sequence from the inside to the outside. The bracket slide cover is fixedly connected to the cleaner bracket, the curved nozzle is fixed with the nozzle head, the driving assembly drives the curved nozzle to reciprocate, the distribution assembly includes a distributor shell, a distributor motor and a distributor pipe head, the distributor motor It is fixedly connected to the distributor pipe head, and the connecting assembly includes several connecting hoses. The distributor pipe head is provided with a nozzle cleaning interface, a buttocks cleaning interface and a female cleaning interface, and the buttocks cleaning interface and the female cleaning interface are respectively connected to the nozzle head through connecting hoses. The nozzle cleaning interface is connected to the nozzle cleaning water inlet provided on the bracket slide cover through a connecting hose. The nozzle cleaning water inlet extends to the inside of the bracket slide cover and is provided with a nozzle cleaning water outlet. The nozzle head is provided with a first water outlet hole and a second water outlet hole corresponding to the buttocks cleaning interface and the female cleaning interface respectively. The curved nozzle and the curved pipe sheath are provided with a third water outlet hole and a fourth water outlet hole at the end opposite to the nozzle head.

[0004] In order to achieve a multi-functional water spraying effect in the above structure, it is realized through a distributor and several connecting hoses. When the nozzle is bent during cleaning, the connecting hose needs to be moved together, which makes the length of the connecting hose longer. In order to avoid the connecting hose from being bent, a spring support sleeve is usually provided on the connecting hose, so that the connecting hose can be easily moved while avoiding being bent. However, the setting of multiple connecting hoses increases the required installation space, resulting in a larger installation space. The installation space inside the toilet is compact, which will cause the connecting hose to contact with other parts when moving, thereby affecting the normal use of the cleaner. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a washer. The technical problem to be solved by the present invention is: how to make the washer compact in structure while achieving multifunctional flushing.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] The cleaning device according to claim 1, wherein the water inlet of the cleaning device is connected to the water inlet of the cleaning device and the water inlet of the cleaning device is connected to the water inlet of the cleaning device.

[0008] When the flushing is completed, the flushing water pipe moves relative to the flushing sleeve until the limit pin abuts against the hole wall at the rear end of the limit hole, driving the flushing sleeve to retract synchronously. During retraction, the elastic positioning member releases the positioning of the flushing sleeve, causing the flushing sleeve and the flushing water pipe to retract synchronously into the shell.

[0009] The above structure only adopts the setting of one flushing water pipe and cooperates with the relative displacement of the flushing sleeve to realize the multi-functional flushing requirements of the washer. Only one flushing water pipe is used, which makes the overall volume of the entire washer smaller and the installation more convenient. Through the cooperation of the flushing water pipe, the flushing sleeve and the elastic positioning part, only one driving part is required to achieve the synchronous movement and relative movement of the two, making the control simpler and more convenient, thereby realizing the multi-functional cleaning of the washer while making the structure more compact.

[0010] In the above-mentioned washer, the flushing water pipe is connected to a limiting bottom shell, the outer side wall of the limiting bottom shell is provided with the above-mentioned limiting pin, the flushing sleeve is arranged on 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 formation of the limit pin is facilitated by connecting a limit bottom shell to the flushing water pipe, and the structure of the existing flushing water pipe will not be changed. It is convenient for loading and unloading, and can also protect the flushing water pipe. It can ensure the multifunctional cleaning of the cleaner while achieving a compact structure of the cleaner.

[0012] In the above-mentioned cleaner, the elastic positioning member is an elastic pin connected to the top of the shell, and a positioning hole for the elastic pin to be embedded is provided on the rear end of the flushing sleeve. The flushing sleeve is provided with a limit plate below the positioning hole. The front end of the limit plate is a guide part, and the rear end is a supporting part. The guide part is inclined from top to bottom and arranged backward, and the lower end of the elastic pin can slide along the guide part. The supporting 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 part, making the flushing sleeve unable to move forward. When flushing is completed, the flushing sleeve moves backward synchronously with the flushing water pipe, and the elastic pin slides out of the positioning hole along the guide part, thereby releasing the positioning between the shell and the flushing sleeve, so that the flushing sleeve and the flushing water pipe can be synchronously retracted into the shell, realizing stable use of the washer, and only adding an elastic pin to the shell, opening a positioning hole and adding a limit plate on the flushing sleeve will not increase the overall installation space, and the normal use of the multi-functional cleaning washer is realized while ensuring the compact structure of the washer.

[0014] The elastic positioning member may also be an elastic plunger or other components.

[0015] In the above-mentioned washer, the limiting plate is U-shaped, the limiting plate and the flushing sleeve are integrally formed, and the guide portion and the abutting portion of the limiting plate are both connected to the hole wall of the positioning hole.

[0016] The limiting plate and the flushing sleeve are integrally formed to make installation more convenient, and the guide part and the abutting part are connected to the hole wall of the positioning hole, which facilitates the insertion and removal of the elastic pin, making the overall installation space required smaller. In addition, the setting of the limiting plate ensures that the elastic pin will not hit the flushing water pipe after insertion, ensuring the normal use of the multi-functional cleaning of the washer.

[0017] In the above-mentioned cleaning device, the water outlet end of the flushing water 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 gear protrusion, and the front end of the flushing sleeve has a water outlet plate arranged on the water outlet head, and a plurality of gear ports are opened on the water outlet plate. When the gear protrusion is embedded in one of the gear ports, the corresponding water outlet is aligned with the flushing port and connected.

[0018] The setting of the shift protrusion can provide a certain positioning resistance after the corresponding water outlet is aligned with the flushing port, thereby making the positioning effect better. Even if the driving part has a slight error when driving the flushing water pipe to move, the shift protrusion and the shift port can be used to limit the position, further ensuring the normal operation of the multi-functional cleaning of the washer.

[0019] In the above-mentioned washer, the front and rear sides of the shift protrusion have guide surfaces with upper ends close to each other and arranged obliquely, and the front and rear sides of the shift opening have guide opening walls that fit with the guide surfaces.

[0020] The cooperation between the guide surface and the guide port wall enables the gear protrusion to be stably moved out of the gear port and quickly embedded into the next guide port wall when the driving member drives the flushing water pipe to move, thereby achieving stable water discharge from the washer gear and facilitating the adjustment of the gear.

[0021] In the above-mentioned washer, the water outlet head is provided with a sealing ring at each water outlet, and when the shift protrusion is embedded in one of the shift outlets, the upper end of the sealing ring abuts against the water outlet plate.

[0022] The setting of the sealing ring ensures the sealing after the water outlet and the flushing port are aligned, and due to the setting of the shift protrusion, when the flushing water pipe moves, the upper end of the sealing ring does not contact the water outlet plate due to the setting of the shift protrusion, so it does not affect the relative movement of the water outlet head and the water outlet plate. When the shift protrusion is embedded in one of the shift ports, the sealing performance can be improved by the contact between the sealing ring and the water outlet plate, thereby ensuring the water outlet effect of the washer.

[0023] In the above-mentioned cleaner, the left and right outer edges of the water outlet plate are folded downward to form an installation flange, the water outlet head is slidably arranged in the installation flange, and the front end of the water outlet plate is folded downward to form a stroke limit flange, and the front end of the water outlet head can be abutted against the stroke limit flange.

[0024] The setting of the installation flange can realize the sliding guidance of the water outlet head, and the setting of the stroke limit flange can prevent the water outlet head from moving excessively and extending out of the water outlet plate when moving in the front and rear directions, thereby improving the stability and safety of the use of the cleaner.

[0025] In the above-mentioned washer, the opening of the limiting bottom shell is set upward, the flushing sleeve is curved and opened downward, the flushing sleeve is clamped on the limiting bottom shell and forms a curved pipe shape, and the flushing water pipe part is located between the flushing sleeve and the limiting bottom shell.

[0026] The limiting bottom shell and the flushing sleeve are connected with each other, making the installation of the entire flushing structure more convenient, and can protect the water outlet end of the flushing pipe and improve the stability of flushing.

[0027] In the above-mentioned cleaner, the driving member is a driving motor arranged outside the shell, the motor shaft of the driving motor is connected to a driving gear, the rear end of the limiting bottom shell is connected to a curved rack, and the rack is engaged with the driving gear.

[0028] By cooperating with the driving gear and the rack, the driving accuracy is improved while the space occupied by the driving flushing water pipe is reduced.

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

[0030] 1. Only one flushing water pipe is used, and the relative displacement of the flushing sleeve is coordinated to realize the multifunctional flushing requirements of the washer. Moreover, only one flushing water pipe is used, which makes the overall volume of the entire washer smaller and the installation more convenient. Moreover, through the coordination of the flushing water pipe, the flushing sleeve and the elastic positioning member, only one driving member is required to realize the synchronous movement and relative movement of the two, making the control simpler and more convenient, thereby realizing the multifunctional cleaning of the washer and making the structure more compact.

[0031] 2. When the flushing sleeve moves forward until the elastic pin is embedded in the positioning hole, the elastic pin abuts against the abutting part, so that the flushing sleeve cannot move forward. When flushing is completed, the flushing sleeve moves backward synchronously with the flushing water pipe, and the elastic pin slides out of the positioning hole along the guide part, thereby releasing the positioning between the shell and the flushing sleeve, so that the flushing sleeve and the flushing water pipe can be synchronously retracted into the shell, thereby realizing stable use of the washer. In addition, only the elastic pin is added to the shell, the positioning hole is opened on the flushing sleeve, and the limit plate is added, which does not increase the overall installation space. While ensuring the compact structure of the washer, the normal use of the washer is realized. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 3 As shown, the cleaning device includes a shell 1 and a flushing water pipe 2 arranged in the shell 1. A water inlet 11 connected to the flushing water pipe 2 is opened on one side of the shell 1. A driving member 3 is fixedly connected to the shell 1. The driving shaft of the driving member 3 is connected to the flushing water pipe 2 and drives the flushing water pipe 2 to move back and forth.

[0044] Specifically, if Figure 3-6As shown, the water outlet end 21 of the flushing water pipe 2 is provided with a flushing sleeve 4, and the water outlet end 21 of the flushing water pipe 2 is provided with multiple water outlets 22. The flushing sleeve 4 is provided with a flushing port 41. A limiting pin 23 is provided on the flushing water pipe 2. The flushing sleeve 4 is provided with a long strip of limiting holes 42 along the moving direction of the flushing water pipe 2. The limiting pin 23 is embedded in the limiting hole 42 and slides along the limiting hole 42 to align and connect any water outlet 22 with the flushing port 41. The limiting pin 23 can abut against the hole walls at the front and rear ends of the limiting hole 42. The shell 1 is provided with an elastic positioning member 5 for positioning the flushing sleeve 4 that partially extends out of the shell 1. The elastic positioning member 5 can release the positioning when the flushing sleeve 4 retracts.

[0045] During cleaning, the driving member 3 drives the flushing water pipe 2 to move forward. When the flushing water pipe 2 moves to the point where the limit pin 23 abuts against the wall of the limit hole 42, the flushing sleeve 4 is driven to move synchronously. The flushing water pipe 2 and the flushing sleeve 4 move synchronously to the elastic positioning member 5 on the shell 1 to position the flushing sleeve 4. At this time, the flushing sleeve 4 partially extends out of the shell 1. According to the flushing demand, the driving member 3 is started 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 with the flushing port 41 and connected, and the external water pump passes the tap water with the corresponding water pressure. The flushing water pipe 2 flows out from the flushing port 41 to realize the flushing function, and the limit pin 23 on the flushing water pipe 2 slides in the limit hole 42 during movement, and the flushing sleeve 4 does not move due to the positioning of the elastic positioning member 5, thereby realizing rapid flushing. When the flushing is completed, the flushing water pipe 2 moves relative to the flushing sleeve 4 until the limit pin 23 abuts against the hole wall at the rear end of the limit hole 42, driving the flushing sleeve 4 to retract synchronously. During retraction, 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 are synchronously retracted into the shell 1.

[0046] The above structure only adopts the setting of one flushing water pipe 2 and cooperates with the relative displacement of the flushing sleeve 4 to realize the multi-functional flushing requirements of the washer. Moreover, only one flushing water pipe 2 is adopted, which makes the overall volume of the entire washer smaller and the installation more convenient. Moreover, through the cooperation of the flushing water pipe 2, the flushing sleeve 4 and the elastic positioning member 5, only one driving member 3 is required to realize the synchronous movement and relative movement of the two, making the control simpler and more convenient, thereby realizing the multi-functional cleaning of the washer while making the structure more compact.

The supporting portion 44b is arranged vertically and can abut against the outer wall of the elastic pin 51. The limit plate 44 is U-shaped, and the limit plate 44 is integrally formed with the flushing sleeve 4. The guide portion 44a and the supporting portion 44b of the limit plate 44 are both connected to the hole wall of the positioning hole 43.

[0049] like Figure 4 and Figure 7 As shown, the water outlet end 21 of the flushing water pipe 2 has a plate-shaped water outlet head 25, the water outlet 22 is opened on the water outlet head 25, the upper part of the water outlet head 25 is raised 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, and a plurality of stop openings 45a are opened on the water outlet plate 45. When the stop protrusion 25a is embedded in one of the stop openings 45a, the corresponding water outlet 22 is aligned with the flushing port 41 and connected. The front and rear sides of the stop protrusion 25a have guide surfaces 25b with upper ends close to each other and inclined. The front and rear sides of the gear 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 gear protrusion 25a is embedded in one of the gear ports, the upper end of the sealing ring 6 abuts against the water outlet plate 45, and the left and right outer edges of the water outlet plate 45 are folded downward to form installation flanges 45c. The water outlet head 25 is slidably set in the installation flanges 45c, and the front end of the water outlet plate 45 is folded downward to form a stroke limit flange 45d. The front end of the water outlet head 25 can abut against the stroke limit flange 45d.

[0050] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, the opening of the limiting bottom shell 24 is set upward, the flushing sleeve 4 is curved and the opening is downward, the flushing sleeve 4 is clamped on the limiting bottom shell 24 and forms a curved pipe shape, and the flushing water pipe 2 is partially located between the flushing sleeve 4 and the limiting bottom shell 24.
