Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a spray nozzle device for a toilet, a method for installing the nozzle thereon, and a smart toilet. Background Technology

[0002] Current smart toilets typically feature a spray nozzle for posterior or feminine washing after use. After a period of use, the nozzle at the tip of the spray nozzle tends to accumulate dirt. To facilitate cleaning, the nozzle is usually designed to be detachable. The spray nozzle needs to be extended for easy removal and installation. However, when installing the nozzle, the extended spray nozzle lacks proper positioning and can easily be pushed into the toilet seat, leading to improper nozzle installation, leaks, or water entering the toilet bowl, thus affecting the user experience. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a toilet spray boom device, a method for installing the nozzle thereon, and a smart toilet, which allows the spray boom to remain extended during nozzle installation to facilitate proper nozzle placement.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: a toilet spray rod device, including a fixed base, a spray rod, and a first driving mechanism. The water outlet end of the spray rod is detachably connected to a nozzle, and the spray rod is slidably connected to the fixed base and driven by the first driving mechanism to extend or retract. The spray rod is movably connected to a limiting member, which can switch to a limiting state or a reset state after the spray rod extends from the fixed base. In the limiting state, the limiting member abuts against the fixed base to restrict the retraction of the extended spray rod. In the reset state, the limiting member cancels the limiting of the spray rod, allowing the extended spray rod to retract.

[0005] Furthermore, it also includes a water path switching component, which is movably connected to the spray bar and driven by a second drive mechanism provided on the spray bar to realize the water path switching of the spray bar; the limiting component is driven by the water path switching component to at least switch to the limiting state.

[0006] A reset component is provided between the limiting component and the spray bar. After the water circuit switching component releases the limiting component, the limiting component automatically returns to the reset state by relying on the reset component.

[0007] Furthermore, the water path switching component is slidably connected to the spray rod along the extension and retraction direction of the spray rod, and the water path switching component pushes the limiting component to the limiting state by sliding in the extension direction of the spray rod.

[0008] Furthermore, the limiting member is rotatably connected to the spray bar, and the rotation axis of the limiting member extends horizontally and is perpendicular to the extension and retraction direction of the spray bar, so that the limiting member switches states by swinging up and down.

[0009] Furthermore, the limiting member has a first end, a second end, and a third end. The first end is rotatably connected to the spray bar. The second end is located in front of the first end in the extension direction of the spray bar and is engaged with the spray bar to reset the limiting member to the reset state. The second end is used to receive the push of the water path switching member. The third end extends downward and is used to abut against the fixed seat.

[0010] Furthermore, the reset member includes an elastic element that is stretched between the limiting member and the spray bar.

[0011] Furthermore, the spray bar is provided with a mounting groove, and the limiting member is located in the mounting groove. The bottom of the mounting groove is provided with a clearance opening for the limiting member to partially enter and exit so as to abut against the fixed seat. A decorative cover is connected to the spray bar, which covers the limiting member, the water path switching member and the nozzle. The front of the fixed seat is provided with a support rib for abutting against the limiting member.

[0012] Furthermore, the first drive mechanism includes a first motor and a first transmission assembly. The first motor is mounted on the fixed base and is connected to the spray bar via the first transmission assembly.

[0013] Furthermore, the second drive mechanism includes a second motor and a second transmission assembly. The second motor is mounted on the spray bar and is connected to the water circuit switching component via the second transmission assembly. The water circuit switching component has an inlet channel and an outlet channel. The spray bar has multiple water passages that connect to the nozzle. The outlet channel is switched to connect with the multiple water passages.

[0014] This invention discloses a method for installing a nozzle on a toilet spray boom assembly. The spray boom assembly includes a fixed base, a spray boom, and a nozzle. The spray boom is slidably connected to the fixed base. When installing the nozzle, the spray boom is first slid out of the fixed base, and then the limiting member connected to the spray boom is switched to a limiting state that abuts against the fixed base to restrict the retraction of the spray boom. After the nozzle is installed to the water outlet end of the spray boom, the limiting member is switched to a reset state to remove the limitation on the spray boom, allowing the spray boom to retract.

[0015] The present invention also provides a smart toilet, including a toilet seat and a smart toilet lid disposed on the toilet seat; it also includes a spray rod device as described above, the spray rod device being mounted on the base of the smart toilet lid.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Because the spray bar is movably connected to a limiting component, the limiting component can switch between a limiting state and a reset state after the spray bar extends from the fixed seat. In the limiting state, the limiting component abuts against the fixed seat to restrict the retraction of the extended spray bar. In the reset state, the limiting component cancels the restriction on the spray bar, allowing the extended spray bar to retract. This invention allows the limiting component to limit the spray bar when it extends and the nozzle is installed, keeping the spray bar stable in the extended state. This facilitates the installation of the nozzle and reduces the probability of water leakage or being flushed into the toilet bowl during use, thus improving the user experience.

[0018] 2. As a preferred embodiment, the present invention utilizes a water circuit switching component to provide the power for the limiting component to switch to the limiting state, and utilizes a reset component that cooperates with the spray bar to reset the limiting component, so that the present invention can automatically switch the state of the limiting component, making it more convenient and labor-saving for users to install the nozzle.

[0019] 3. The limiting component is rotatably connected to the spray bar, and the rotation axis of the limiting component extends horizontally and is perpendicular to the extension and retraction direction of the spray bar, which makes the assembly of the limiting component simpler and reduces the space occupied.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the present invention, including the spray bar device for a toilet, the method for installing the nozzle, and the smart toilet, is not limited to the embodiments.

Detailed Implementation

[0034] In this invention, the terms "first," "second," and "third," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "front," and "rear" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is only for the convenience of describing the invention, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; 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.

[0035] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" refers to two or more. In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] Please see Figures 1-10 As shown, a toilet spray boom device of the present invention includes a fixed base 1, a spray boom 2, and a first driving mechanism. A nozzle 3 is detachably connected to the water outlet end of the spray boom 2, and the spray boom 2 is slidably connected to the fixed base 1 and driven by the first driving mechanism to extend or retract. A limiting member 4 is movably connected to the spray boom 2. This limiting member 4 can switch between a limiting state and a reset state after the spray boom 2 extends from the fixed base 1. In the limiting state, the limiting member 4 abuts against the fixed base 1 to restrict the retraction of the extended spray boom 2. In the reset state, the limiting member 4 releases the limiting effect on the spray boom 2, allowing it to retract. Therefore, when the spray boom 2 extends and the nozzle 3 is installed, the present invention can utilize the limiting member 4 to limit the spray boom 2, stabilizing it in the extended state, thereby facilitating the installation of the nozzle 3.

[0037] The invention also includes a water path switching component 5, which is movably connected to the spray bar 2 and driven by a second drive mechanism on the spray bar 2 to achieve water path switching. Specifically, the water path switching component 5 has an interconnected inlet channel 51 and an outlet channel (located on the back of the water path switching component, not shown in the figure). The spray bar 2 has multiple spray bar water passages 22 that connect to the nozzle 3, for use in posterior washing, feminine washing, and bowel movement assistance, etc. The inlet end of the inlet channel 51 is connected to an inlet pipe 20, and the outlet channel is switched to connect with the multiple water passages 22 to achieve water path switching. A decorative cover 8 is connected to the spray bar 2, which covers the limiting component 4, the water path switching component 5, and the nozzle 3, making the whole structure more compact and aesthetically pleasing.

[0038] In a preferred embodiment, the aforementioned limiting member 4 is driven by the water channel switching member 5 to at least switch to the limiting state, and a reset member cooperates between the limiting member 4 and the spray bar 2 to provide the limiting member 4 to return to the reset state. Specifically, the water channel switching member 5 is slidably connected to the spray bar 2 along the extension direction of the spray bar 2, and the water channel switching member 5 pushes the limiting member 4 to the limiting state by sliding in the extension direction of the spray bar 2. In other embodiments, the limiting member 4 is manually operated to switch to the limiting state, or the limiting member 4 is driven by the water channel switching member to achieve the switching between two states (i.e., the limiting state and the reset state). In other embodiments, the limiting member 4 is driven by an additional set of driving mechanisms or a transmission structure linked to a second driving mechanism to achieve the state switching.

[0039] In this embodiment, the limiting member 4 is rotatably connected to the spray bar 2, and the rotation axis of the limiting member 4 extends horizontally and is perpendicular to the extension and retraction direction of the spray bar 2, so that the limiting member 4 switches states by swinging up and down. The extension and retraction direction of the spray bar 2 is specifically the front-to-back direction of the toilet, so the rotation axis of the limiting member 4 extends along the left-to-right direction of the toilet.

[0040] like Figure 2 As shown, the limiting member 4 has a first end 41, a second end 42, and a third end 43 arranged in a triangular pattern. The first end 41 has a shaft hole 411, which cooperates with the rotating shaft 7 to allow the limiting member 4 to be rotatably connected to the spray bar 2. The second end 42 is located in front of the first end 41 in the extension direction of the spray bar 2, and a reset member is fitted between it and the spray bar 2. The second end 42 is used to receive the push of the water path switching member 5. The third end 43 extends downward and is used to abut against the fixed base 1. Specifically, the limiting member 4 is roughly Y-shaped.

[0041] like Figure 3 As shown, the spray bar 2 is provided with a mounting groove 21, and the limiting member 4 is rotatably installed in the mounting groove 21 (e.g., Figure 4 As shown), the bottom of the mounting groove 21 has a clearance opening 211 for allowing a portion of the limiting member 4 (i.e., the third end 43 of the limiting member 4) to enter and exit so as to abut against the fixing seat 1. Figure 5 As shown, the front of the fixed base 1 is provided with a support rib 11 for engaging with the limiting member 4.

[0042] The aforementioned reset component includes an elastic element 6, which is positioned between the second end 42 of the limiting component 4 and the spray bar 2. Specifically, the elastic element 6 is a helical spring, with its two ends abutting against the second end 42 of the limiting component 4 and the bottom of the mounting groove 21. The second end 42 of the limiting component 4 and the bottom of the mounting groove 21 are respectively provided with positioning holes 421 / 212 to provide positioning for the two ends of the elastic element 6. The positioning holes 421 are as follows: Figure 8 As shown, positioning hole 212 Figure 3 As shown.

[0043] In this embodiment, the first driving mechanism includes a first motor 9 and a first transmission assembly. The first motor 9 is mounted on the fixed base 1 and is connected to the spray bar 2 via the first transmission assembly. The first transmission assembly may be, for example, a gear transmission assembly, which is prior art and will not be described further.

[0044] In this embodiment, the second drive mechanism includes a second motor 10 and a second transmission assembly. The second motor 10 is mounted on the spray bar 2 and is connected to the water path switching component 5 via the second transmission assembly. The second transmission assembly specifically includes a gear 101 and a rack 52. The gear 101 is mounted on the output shaft of the second motor 10, and the rack 52 is fixed to the water path switching component 5 and extends along the sliding direction of the water path switching component 5. The gear 101 meshes with the rack 52.

[0045] The present invention provides a toilet spray boom device. When the nozzle 3 needs cleaning, the nozzle 3 cleaning program is activated, causing the first motor 9 to drive the spray boom 2 to extend. Then, the second motor 10 drives the water circuit switching component 5 to slide forward and push the limiting component 4. After being pressed, the limiting component 4 overcomes the elastic force of the elastic component 6 and swings downward, causing its third end 43 to extend downward and abut against the support rib 11 at the front of the fixed base 1. Figure 9 , Figure 10 As shown. Then, remove nozzle 3 for cleaning. When installing nozzle 3, the spray bar 2 is fixed in place because the limiting member 4 is stuck on the support rib 11 at the front of the fixed base 1. After the nozzle 3 is installed in place, the nozzle 3 cleaning program is turned off. At this time, the first motor 9 drives the spray bar 2 to move forward a small distance, so that the limiting member 4 is separated from the support rib 11 at the front of the fixed base 1, so as to prevent the limiting member 4 from being stuck by the fixed base 1 and unable to reset. Next, the second motor 10 drives the water circuit switching member 5 to slide back and move away from the limiting member 4, that is, no longer pressing against the limiting member 4. Then, the limiting member 4 swings upward and resets under the restoring force of the elastic member 6, so that its third end 43 is put into the mounting groove 21 of the spray bar 2, thereby releasing the limitation with the support rib 11, so that the spray bar 2 is put into the fixed base 1 under the drive of the first motor 9. The working position of the water circuit switching component 5 when switching water circuits is different from the working position of the water circuit switching component 5 when the driving limit component 4 is switched to the limit state, so as to avoid accidentally triggering the limit component 4 when switching water circuits.

[0046] Therefore, after the spray bar 2 device has been used for a period of time, the present invention makes it convenient for users to disassemble and clean the nozzle 3. When installing the nozzle 3, the spray bar 2 will not be pushed into the fixed seat 1 under the limit of the limiting member 4, but will remain in the extended state, which makes it easy for the nozzle 3 to be installed in place. This avoids the nozzle 3 from leaking or being flushed into the toilet bowl when it is used due to improper installation.

[0047] The present invention discloses a method for installing a nozzle on a toilet spray boom device. The spray boom device includes a fixed base, a spray boom, and a nozzle. The spray boom is slidably connected to the fixed base. When installing the nozzle, the spray boom is first slidably extended out of the fixed base, and then the limiting member connected to the spray boom is switched to a limiting state that abuts against the fixed base to restrict the retraction of the spray boom. After the nozzle is installed to the water outlet end of the spray boom, the limiting member is switched to a reset state to cancel the limitation on the spray boom and allow the spray boom to retract.

[0048] Furthermore, when installing the nozzle onto the water outlet end of the spray bar, first move the spray bar a certain distance in the extension direction to completely separate the limiting component from the fixed seat, so as to avoid the limiting component being stuck by the fixed seat and unable to reset, and then switch the limiting component to the reset state.

[0049] In this embodiment, the spray boom device further includes a first driving mechanism, which drives the spray boom to extend or retract. A water path switching component for switching water paths is movably connected to the spray boom, and this water path switching component drives a limiting component to at least switch to a limited state. Specifically, the water path switching component is slidably connected to the spray boom along the extension and retraction direction of the spray boom and is driven by a second driving mechanism mounted on the spray boom. The water path switching component switches to the limited state by sliding the limiting component. Preferably, a reset component is provided between the limiting component and the spray boom to allow the limiting component to return to its reset state. This reset component is preferably an elastic component, but is not limited to this.

[0050] The method for installing a nozzle in a toilet spray boom device according to the present invention can be implemented using the toilet spray boom device of the present invention described above. Therefore, the specific working principle is described above and will not be repeated here.

[0051] Please see Figure 11 , Figure 12 As shown, a smart toilet of the present invention includes a toilet seat 30 and a smart toilet lid 40 disposed on the toilet seat; it also includes a spray rod device as described above, which is mounted on the base of the smart toilet lid 40.

[0052] The present invention provides a smart toilet in which the above-mentioned limiting member 4 is provided on the spray boom device, which facilitates the user to operate and install the nozzle 3 with one hand, thereby improving the user experience.

[0053] The present invention relates to a toilet spray bar device and a method for installing the nozzle thereon, as well as a smart toilet. The parts not described herein are the same as or can be implemented using existing technologies.

[0054] The above embodiments are only used to further illustrate the toilet spray bar device and the method for installing the nozzle of the toilet and the smart toilet of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
