Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a flushing device with a detachable nozzle and a smart toilet. Background Technology

[0002] Many existing smart toilets are equipped with a flushing device that provides functions such as posterior washing, feminine washing, and self-cleaning. The flushing device includes a fixed part, a drive part, and a spray bar assembly. The spray bar assembly includes a spray bar, a switching element, and nozzles. The spray bar slides onto the fixed part and is driven by the drive part to extend or retract. The switching element is slidably mounted on the spray bar and switches the water output function by sliding. The nozzles are located at the water outlet end of the spray bar and have multiple water outlets corresponding to the spray bar's water output function. Because the spray bar is extended during flushing and the nozzles are exposed, they are easily exposed to dirt and require regular cleaning. Furthermore, when the nozzles malfunction, they need to be removed for replacement or repair. Therefore, making the nozzles detachable is particularly necessary. However, for aesthetic reasons, the spray bar and nozzles are usually covered by a decorative cover, making it inconvenient for users or maintenance personnel to remove the nozzles. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a flushing device with an easily detachable nozzle and a smart toilet.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a flushing device with a convenient nozzle disassembly, comprising a fixed base, a spray bar, a nozzle, and a switching component. The spray bar is slidably fitted to the fixed base along a preset direction, and the switching component is slidably fitted to the spray bar along the preset direction. The nozzle is detachably connected to the water outlet end of the spray bar. It also includes a pushing component, which is slidably fitted to the spray bar along the preset direction and located between the switching component and the nozzle. As the spray bar slides, the pushing component switches to a first state where it is abutted by the fixed base or a second state where it is separated from the fixed base and reset. In the first state, the switching component pushes the pushing component by sliding, causing the pushing component to push the nozzle, thereby ejecting the nozzle or making the nozzle suitable for removal. In the second state, the spray bar is in an extended state, and the switching component switches the water outlet function of the spray bar by sliding.

[0005] Furthermore, the pushing member includes a push rod and a protrusion. The push rod is slidably engaged with the spray bar, with one end facing the switching member and the other end facing the nozzle. The protrusion is located at one end of the push rod and passes downward through the spray bar. In the first state, the protrusion is pushed upward by the fixed seat, raising one end of the push rod so that it can be pushed by the switching member. In the second state, the protrusion is separated from the fixed seat, and one end of the push rod is reset downward by its own weight and / or the action of the reset member.

[0006] Furthermore, the reset member includes a spring arm disposed at one end of the push rod and / or the protrusion. In the second state, the switching member pushes the spring arm to reset one end of the push rod downwards; and / or, the reset member includes an elastic element that engages between the push rod and the spray bar.

[0007] Furthermore, the surface of the spring arm that is pushed by the switching member is lower than the top end of one end of the push rod, and / or the surface of the spring arm that is pushed by the switching member is a slope, with the bottom end of the slope facing the switching member and the top end of the slope away from the switching member.

[0008] Furthermore, the spring arm is bent, with one end fixed to the push rod or the protrusion, and the other end located between the push rod and the switching member, so that it can be pushed by the switching member.

[0009] Furthermore, the bottom of the protrusion is provided with a guide surface suitable for guiding the protrusion when switching from the second state to the first state.

[0010] Furthermore, the nozzle is fitted onto the water outlet end of the spray rod, and the nozzle is provided with a guide rod that is inserted into a guide groove provided at the water outlet end of the spray rod. The pushing member partially enters the guide groove and is opposite to the tail end of the guide rod.

[0011] Furthermore, the switching element pushes the pushing element when the spray bar slides to a designated position relative to the fixed seat in the extension direction; it also includes a decorative cover, which is attached to the spray bar and covers the spray bar, the switching element, the pushing element and the nozzle.

[0012] Furthermore, a first driving mechanism is provided on the fixed base, which is in transmission cooperation with the spray bar to drive the spray bar to slide relative to the fixed base; a second driving mechanism is provided on the spray bar, which is in transmission cooperation with the switching component to push the switching component to slide relative to the spray bar; the switching component is provided with a water inlet channel, the spray bar is provided with multiple water outlet channels for switching communication with the water inlet channel, and the nozzle is provided with multiple water outlet holes corresponding to and communicating with the multiple water outlet channels.

[0013] The present invention also provides a smart toilet, including a toilet body and a flushing device with a detachable nozzle as described above, wherein the fixing seat is mounted on the toilet body and the preset direction is the front-rear direction of the toilet body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Because the present invention also includes the aforementioned pushing member, when it is necessary to disassemble the nozzle, the switching member can be used to push the pushing member, causing the pushing member to push the nozzle, thereby ejecting the nozzle or making the nozzle suitable for removal, thus making nozzle disassembly more convenient and labor-saving. In particular, the pushing member has a first state of being abutted by the fixed seat and a second state of being separated from the fixed seat and reset, and the switching member can only push the pushing member in the first state, while in the second state it can only be used to switch the water outlet function, thereby avoiding the situation where the switching member accidentally pushes the pushing member.

[0016] 2. The pusher preferably includes the push rod and the protrusion, which makes the structure of the pusher simpler and makes it easier to cooperate with the fixed seat and the switching part.

[0017] 3. The reset component preferably includes the spring arm, eliminating the need for separate assembly and simplifying the overall structure.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the flushing device with a convenient detachable nozzle and the smart toilet of the present invention are not limited to the embodiments.

Therefore, it should not be construed as a limitation on the scope of protection of this invention. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Furthermore, in the description of this invention, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Please see Figures 1-14 As shown, this invention provides a convenient rinsing device with a detachable nozzle for rinsing the human private parts, such as for posterior washing or feminine wash. It includes a fixed base 1, a spray bar 2, a nozzle 3, and a switching element 4. The spray bar 2 is slidably fitted to the fixed base 1 along a preset direction, and the switching element 4 is slidably fitted to the spray bar 2 along the preset direction. The nozzle 3 is detachably connected to the water outlet end of the spray bar 2. It also includes a pushing element 5, which is slidably fitted to the spray bar 2 along the preset direction and located between the switching element 4 and the nozzle 3. As the spray bar 2 slides, the pushing element 5 can switch to a first state where it is pressed against the fixed base 1 or a second state where it is separated from the fixed base 1 and reset. In the first state, the pushing element 5 can be pushed by the switching element 4. Therefore, the switching element 4 can push the pushing element 5 by sliding, causing the pushing element 5 to push the nozzle 3, thus ejecting or making the nozzle 3 suitable for removal. In the second state, the spray bar 2 is in the extended state, and the switching element 4 cannot push the nozzle 3 by pushing the pushing element 5, but can switch the water outlet function of the spray bar 2 by sliding. Specifically, the switching component 4 is provided with a water inlet channel, the spray bar 2 is provided with multiple water outlet channels for switching and communicating with the water inlet channel, and the nozzle 3 is provided with multiple water outlet holes corresponding to and communicating with the multiple water outlet channels. The preset direction is specifically the front-back direction.

[0039] In a preferred embodiment, the pusher 5 includes a push rod 51 and a protrusion 52. The push rod 51 is slidably engaged with the spray bar 2, with one end 511 of the push rod facing the switching member 4 and the other end 512 facing the nozzle 3. Specifically, the spray bar 2 is provided with a groove 21 adapted to the push rod 51, and the push rod 51 is slidably disposed in the groove 21. The protrusion 52 is located at one end 511 of the push rod and passes downward through the spray bar 2. In a first state, the bottom of the protrusion 52 is pushed upward by the fixing seat 1, raising one end 511 of the push rod so that it can be pushed by the switching member 4. In a second state, the protrusion 52 separates from the fixing seat 1, and one end 511 of the push rod is reset downward by its own weight and / or the action of the reset member. One end 511 of the push rod is the rear end of the push rod 51, and the other end 512 of the push rod is the front end of the push rod 51.

[0040] In this embodiment, the reset member includes a spring arm 53 disposed at one end 511 of the push rod and / or the protrusion 52. In the second state, the switching member 4 pushes the spring arm 53 to reset one end 511 of the push rod downward. The surface of the spring arm 53 that is pushed by the switching member 4 is lower than the top of one end 511 of the push rod, and the surface of the spring arm 53 that is pushed by the switching member 4 is a slope 531. The bottom end of the slope 531 faces the switching member 4, and the top end of the slope 531 is away from the switching member 4, that is, the slope 531 is high in the front and low in the back.

[0041] Preferably, the spring arm 53 is bent, with one end fixed to the push rod 51 or the protrusion 52, and the other end located between the push rod 51 and the switching member 4, so that it can be pushed by the switching member 4. Therefore, the top surface of the other end of the spring arm 53 is lower than the top of the push rod 511 and forms the slope 531, which is specifically an inclined surface. The spring arm 53 is specifically V-shaped, but not limited to this.

[0042] Preferably, the bottom of the protrusion 52 is provided with a guide surface 521 suitable for guiding the protrusion 52 when switching from the second state to the first state. This guide surface 521 is an arc surface that is low in the middle and high at both ends, such as... Figure 2 As shown. The protrusion 52 is elongated, but not limited to this.

[0043] In this embodiment, the nozzle 3 is fitted onto the water outlet end of the spray rod 2, and the nozzle 3 is provided with a guide rod 31 that inserts into the guide groove set in the water outlet end of the spray rod 2. The other end 512 of the push rod enters the guide groove 22 and is opposite to the tail end of the guide rod 31. There are multiple guide rods 31, specifically two, which are arranged approximately symmetrically from left to right. There are also two guide grooves 22, which correspond one-to-one with the two guide rods 31. The guide grooves 22 have a certain limiting effect on the push rod 51, so that the push rod 51 will not slide out from the front end of the guide groove 22 after the nozzle 3 is removed. Specifically, the guide groove 22 is narrow at the front and wide at the back, and the front part of the push rod 51 is also approximately narrow at the front and wide at the back, and the two match each other.

[0044] The flushing device of the present invention also includes a decorative cover 6, which is connected to the spray rod 2 and covers the spray rod 2, the switching component 4, the pushing component 5, and the nozzle 3. The front end of the decorative cover 6 has multiple water passages that correspond one-to-one with the multiple water outlets of the nozzle 3. When the spray rod 2 slides relative to the fixed seat 1 in the extension direction to a designated position, the switching component 4 pushes the pushing component 5, making the nozzle 3 clearly visible after being pushed by the pushing component 5, so that it can be easily removed. This is because when the flushing device of the present invention is applied to a toilet, its spray rod 2 is roughly hidden in the retracted state. At this time, if the nozzle 3 is pushed out by the pushing component 5, the nozzle 3 may still be hidden, requiring the user to bend over to see it.

[0045] A first drive mechanism is provided on the fixed base 1. This first drive mechanism is in transmission cooperation with the spray bar 2 to drive the spray bar 2 to slide relative to the fixed base 1. The first drive mechanism specifically includes a telescopic motor 7 and a first transmission assembly. The telescopic motor 7 is mounted on the fixed base 1 and is connected to the spray bar 2 through the first transmission assembly to drive the spray bar 2 to slide back and forth. A second drive mechanism is provided on the spray bar 2. This second drive mechanism is in transmission cooperation with the switching element 4 to push the switching element 4 to slide relative to the spray bar 2. The second drive mechanism specifically includes a switching motor 8 and a second transmission assembly. The switching motor 8 is mounted at the rear of the spray bar 2 and is connected to the switching element 4 through the second transmission assembly to drive the switching element 4 to slide back and forth.

[0046] In this embodiment, the number of pushers 5 is one, but it is not limited to this. In other embodiments, the number of pushers 5 is two, and the two pushers 5 are arranged side by side.

[0047] This invention provides a flushing device with a conveniently detachable nozzle, applicable to toilets, particularly smart toilets. When the nozzle 3 needs to be removed, first activate the telescopic motor 7, causing it to drive the spray bar 2 to slide in the extension direction (i.e., forward) to a designated position, allowing the nozzle 3 to extend beyond the fixed base 1. Figure 5 As shown. At this time, the bottom of the protrusion 52 of the pusher 5 remains in contact with the fixed base 1, so one end 511 (i.e., the rear end) of the push rod remains raised, as shown. Figure 5 , Figure 6 As shown. Next, the switching motor 8 is started, causing the switching motor 8 to drive the switching element 4 to slide forward. The switching element 4 first contacts the other end of the spring arm 53 of the pusher 5. Since the top surface of the other end of the spring arm 53 is lower than the top of the push rod end 511 and is a slope 531, and the fixed seat 1 is kept in an upward pushing position against the protrusion 52, after the switching element 4 contacts the other end of the spring arm 53, it will cause the spring arm 53 to deform, thereby creating a clearance, so that the switching element 4 finally contacts the push rod end 511, as shown. Figures 7-9 As shown, as the switching element 4 continues to slide forward, it pushes the push rod 51 forward, causing the push rod 51 to slide forward and press against the guide rod 31 of the nozzle 3, thereby pushing the nozzle 3 out, as shown. Figure 10 , Figure 11 As shown. At this point, nozzle 3 is partially exposed outside the decorative cover 6. The user can simply pull off nozzle 3 to complete the disassembly process. After nozzle 3 is disassembled, the switching motor 8 reverses direction, driving the switching component 4 to return to its initial position.

[0048] When reinstalling nozzle 3, simply align the guide rod 31 on nozzle 3 with guide groove 22 and fit nozzle 3 onto the front end of spray bar 2 (i.e., the water outlet end of spray bar 2). As nozzle 3 is installed in place, push rod 51 is pushed back to its initial position by nozzle 3, which provides space for nozzle 3 installation and prepares for the next push of nozzle 3.

[0049] During normal rinsing, the spray bar 2 extends forward to its full position. At this time, the pusher 5 completely disengages from the fixed base 1, causing one end 511 of the pusher to return to its downward position. Therefore, when the switching element 4 slides forward, it will not contact the pusher 5, allowing for normal switching of the water output function. Figure 12 As shown. After rinsing is completed, as the spray bar 2 retracts, the protrusion 52 of the pusher 5 finally returns to the state where it is pushed upward by the fixed seat 1. Since the bottom of the protrusion 52 is provided with a guide surface 521, the protrusion 52 can smoothly transition from the second state to the first state.

[0050] When the pusher 5 is completely separated from the fixed base 1, if one end 511 of the push rod fails to return to its normal downward position, as the switching member 4 slides forward, the switching member 4 will first contact the other end of the spring arm 53 of the pusher 5. Since the top surface of the other end of the spring arm 53 is a slope 531, and the pusher 5 loses the top limit of the fixed base 1, when the switching member 4 contacts and pushes the other end of the spring arm 53, the spring arm 53 is subjected to downward pressure, and drives one end 511 of the push rod to move downward together, thereby realizing the downward reset of one end 511 of the push rod and avoiding the switching member 4, ensuring that the switching member 4 can normally switch the water outlet function.

[0051] like Figure 15 , Figure 16 As shown, in an exemplary embodiment of the present invention, the reset member includes an elastic element that engages between the push rod 51 and the spray rod 2. This elastic element is specifically a torsion spring 9, but is not limited to this. The torsion spring 9 is mounted on the spray rod 2, and its two legs respectively abut against the spray rod 2 and the push rod 51. Specifically, the push rod 51 is provided with a limiting portion 513 to engage with one of the legs 91 of the torsion spring 9. Thus, when the protrusion 52 is completely disengaged from the fixing seat 1, one end 511 of the push rod is reset downwards under the elastic force of the torsion spring 9, thereby avoiding the switching element 4.

[0052] The present invention discloses a smart toilet, comprising a toilet body and a flushing device with a detachable nozzle as described above. A fixing base 1 is mounted on the toilet body, and the preset direction is the front-to-back direction of the toilet body. The toilet body specifically includes a toilet seat and a smart toilet lid mounted on the toilet seat.
