Description

Technical Field

[0001] This invention relates to the field of toilet technology, and in particular to a toilet spray bar self-cleaning device and method and a smart toilet seat. Background Technology

[0002] With rapid economic development, increased incomes, and a growing emphasis on quality of life, smart bathroom fixtures are entering more and more homes. Smart toilets, as a prime example, are gaining popularity in homes and high-end hotels due to their health, comfort, cleanliness, and hygiene features. Smart toilets offer many special functions, such as washing, warm air drying, and automatic flushing. The washing function uses a spray assembly to perform posterior or feminine washes: during washing, the spray nozzle extends, spraying water upwards to clean the corresponding areas of the body; at the end of washing, the nozzle retracts. Currently, existing washing assemblies typically include a self-cleaning function, featuring a self-cleaning orifice that sprays water downwards to clean the outer surface of the retractable spray nozzle when activated. However, the water pressure and flow rate from the self-cleaning orifice are limited, resulting in poor cleaning of the nozzle's outer surface. Consequently, after a period of use, dirt easily accumulates on the nozzle's surface, affecting the overall appearance of the smart toilet and the user's washing experience. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a toilet spray bar self-cleaning device and method, as well as a smart toilet seat, which can effectively remove dirt adhering to the outer surface of the spray bar.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a toilet spray bar self-cleaning device, including a flushing assembly for posterior washing and / or feminine washing, the flushing assembly including a fixed base and a spray bar, the spray bar being slidably disposed on the fixed base so as to be extendable or retractable; it also includes a cleaning assembly, the cleaning assembly including a driving member and a cleaning member, the cleaning member being disposed on the driving member, the driving member being disposed on a mounting member, and driving the cleaning member to contact or separate from the outer surface of the spray bar, and in the state of contact between the cleaning member and the outer surface of the spray bar, as the spray bar extends or retracts, the cleaning member scrapes or brushes the outer surface of the spray bar.

[0005] Furthermore, the drive unit includes a cover that is flip-up and flip-down connected to the mounting unit, and the cleaning unit is disposed on the cover; in the retracted state of the spray bar, the cover is located in front of the spray bar and blocks the spray bar.

[0006] Furthermore, as the spray bar extends, the spray bar pusher cover flips upward and opens until the cleaning component contacts the outer surface of the spray bar.

[0007] Furthermore, the cover is provided with a sliding guide to slide with the spray bar when the cover is pushed up by the spray bar.

[0008] Furthermore, the sliding guide is a wedge-shaped block located inside the cover, and its inclined surface is used to slide with the spray bar.

[0009] Furthermore, the cover includes a first baffle and a second baffle fixed together at a preset angle. The first baffle is on top, and the upper end of the first baffle is rotatably connected to the mounting component. The second baffle is on the bottom and tilts to one side of the spray bar when the spray bar is retracted. The cleaning component is installed on the inner side of the lower end of the first baffle and extends along the extension direction of the second baffle.

[0010] Furthermore, the cleaning assembly also includes a preload member that provides a preload force to the cleaning component and / or the cover when the cleaning component contacts the outer surface of the spray bar, so as to make the cleaning component adhere tightly to the outer surface of the spray bar.

[0011] Furthermore, the preload is an elastic element, which is tensioned between the cover and the mounting component.

[0012] Furthermore, the cleaning component is a cleaning brush used to scrub the outer surface of the spray bar; the cleaning component and the drive component are detachably connected.

[0013] Furthermore, the mounting component is located on the mounting base, or the mounting component is the outer cover of the smart toilet seat.

[0014] The present invention also provides a self-cleaning method for a toilet spray bar, which uses a cleaning component to clean the toilet spray bar. The cleaning component includes a driving component and a cleaning component. During cleaning, the driving component drives the cleaning component to a state of contact with the outer surface of the spray bar, and scrapes or brushes the outer surface of the spray bar as the spray bar extends or retracts. When cleaning is finished, the driving component drives the cleaning component away from the outer surface of the spray bar.

[0015] Furthermore, the drive unit includes a flip-up cover, and the cleaning component is disposed on the cover. When the spray bar is retracted, the cover covers the front side of the spray bar. When cleaning is started, the spray bar extends and pushes the cover, causing the cover to flip up and open, and the cleaning component to contact the outer surface of the spray bar.

[0016] The present invention also provides a smart toilet seat, including the toilet spray bar self-cleaning device as described above.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Since the present invention also includes a cleaning component, which includes a driving component and a cleaning component, the cleaning component is disposed on the driving component, and the driving component is disposed on a mounting component, and drives the cleaning component to contact or separate from the outer surface of the spray bar. In the state where the cleaning component is in contact with the outer surface of the spray bar, as the spray bar extends or retracts, the cleaning component scrapes or brushes the outer surface of the spray bar. Therefore, compared with the self-cleaning rinsing method of the prior art, the present invention can more effectively remove the dirt attached to the outer surface of the spray bar, thereby greatly improving the cleaning effect of the spray bar.

[0019] 2. Since the driving component includes a cover that can be flipped up and down, when the spray bar is retracted, the cover is located on the front side of the spray bar and blocks the spray bar. This invention can use the cover to block and protect the retracted spray bar, which not only makes the overall appearance simpler and more beautiful, but also reduces the spray bar from coming into contact with dirty water, urine, etc. when it is retracted.

[0020] 3. The present invention allows the push cover to flip open upwards when the spray bar extends, until the cleaning component contacts the outer surface of the spray bar. This eliminates the need for a power component to drive the cleaning assembly, making the overall structure simpler, easier to assemble, and reducing production costs.

[0021] 4. The cleaning component and the drive component are detachably connected, allowing the cleaning component to be removed for cleaning or replacement periodically.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the toilet spray bar self-cleaning device and method and the smart toilet seat of the present invention are not limited to the embodiments.

[0035] Example 1

[0036] Please see Figures 1-8As shown, a toilet spray bar self-cleaning device of the present invention includes a flushing assembly for posterior washing and / or feminine washing. The flushing assembly includes a fixed base 1 and a spray bar 2. The spray bar 2 is slidably mounted on the fixed base 1 and can extend or retract. The spray bar 2 is driven to extend and retract by a drive mechanism mounted on the fixed base 1. The present invention also includes a cleaning assembly, which includes a drive member and a cleaning member. The cleaning member is mounted on the drive member and the two are detachably connected. The drive member is mounted on a mounting member and drives the cleaning member to contact or separate from the outer surface of the spray bar 2. When the cleaning member is in contact with the outer surface of the spray bar 2, as the spray bar 2 extends or retracts, the cleaning member scrapes or brushes the outer surface of the spray bar 2. In this embodiment, the outer surface of the spray bar 2 includes the upward-facing outer surface (i.e., the top surface of the spray bar 2), because the upward-facing outer surface of the spray bar 2 is more likely to come into contact with dirt, such as urine, dust, etc. Therefore, the cleaning member at least brushes or scrapes the upward-facing outer surface of the spray bar 2.

[0037] In this embodiment, the driving component includes a rotating component that is rotatably connected to the mounting component. The rotation axis of the rotating component is located in the left-right direction. The cleaning component is disposed on the rotating component. Therefore, the rotating component rotates to cause the cleaning component to contact or separate from the outer surface of the spray bar 2. Specifically, the rotating component is a cover 3. In the retracted state of the spray bar 2, the cover 3 is located in front of the spray bar 2 and covers the spray bar 2, making the overall appearance simpler and more beautiful, and reducing the contact of the spray bar 2 with dirty water, urine, etc. In other embodiments, the cleaning component is located above the spray bar 2. When it is necessary to clean the outer surface of the spray bar 2, the driving component drives the cleaning component to move downward, so that the cleaning component contacts the outer surface of the spray bar 2 for brushing or scraping.

[0038] In this embodiment, the cover 3 is opened by the spray bar 2. Specifically, when the spray bar 2 extends, it pushes the cover 3 upward to flip open until the cleaning component (i.e., the cleaning brush 4) contacts the outer surface of the spray bar 2. In other embodiments, the driving component of the present invention also includes a power component, which drives the rotating component (i.e., the cover 3) to rotate. The power component can be, for example, a motor or a linear actuator (e.g., a cylinder).

[0039] In this embodiment, the cleaning component is specifically a cleaning brush 4, used to scrub the outer surface of the spray bar 2. However, it is not limited to this. In other embodiments, the cleaning component is a scraper, used to scrape the outer surface of the spray bar 2.

[0040] In this embodiment, the cover 3 is provided with a sliding guide portion to slide and engage with the spray rod 2 when the spray rod 2 pushes against the cover 3, thereby preventing jamming and affecting the normal extension and retraction of the spray rod 2. The sliding guide portion is specifically a wedge-shaped block 311, which is disposed on the inner side of the cover 3, such as... Figure 2 As shown, the inclined surface of the wedge block 311 is used for sliding engagement with the spray bar 2.

[0041] like Figure 2 As shown, the cover 3 includes a first baffle 31 and a second baffle 32 fixed together at a preset angle. The first baffle 31 is on top, and its upper end is rotatably connected to the mounting component. The second baffle 32 is on the bottom and tilts to one side of the spray bar 2 when the spray bar 2 is retracted. The length of the first baffle 31 is greater than the length of the second baffle 32, and the angle formed between the first baffle 31 and the second baffle 32 is greater than or equal to 90°. The cleaning component (i.e., the cleaning brush 4) is installed on the inner side of the lower end of the first baffle 31 and extends along the extending direction of the second baffle 32. Specifically, the cover 3 has a mounting slot 312 at the mounting location of the cleaning brush 4, and the cleaning brush 4 can be plugged into the mounting slot 312. Specifically, the cleaning brush 4 is inserted laterally into the mounting slot 312. Therefore, when it is necessary to clean or replace the cleaning brush 4, the cleaning brush 4 can be removed simply by pulling it laterally out of the mounting slot 312. The cleaning brush 4 specifically includes a brush base 41 and bristles 42. A mounting slot 312 is located between the lower end of the first baffle 31 and the second baffle 32. The brush base 41 of the cleaning brush 4 is laterally inserted into the mounting slot 31, and the bristles 42 extend along the extending direction of the second baffle 32. The aforementioned sliding guide (i.e., wedge block 311) is located on the inner side of the first baffle 31, with its narrower end facing the upper end of the first baffle 31 and its wider end facing the lower end of the second baffle 32.

[0042] In this embodiment, the mounting component is the outer cover 5 of the smart toilet seat. The cover 3 is connected to the front end of the outer cover 5 by a rotating shaft 6 extending to the left and right. The upper left and right ends of the cover 3 are respectively provided with shaft hole seats 413 that cooperate with the rotating shaft 6. In other embodiments, the mounting component is set on the fixed base. In this case, the mounting component can be integrally formed with the fixed base or it can be a separate molded part and installed on the fixed base.

[0043] The present invention provides a toilet spray bar self-cleaning device, the standby state of which is as follows: Figure 3 , Figure 4 As shown, at this time, the spray bar 2 retracts into the fixed base 1, the cover 3 is in a lowered state and covers the front side of the spray bar 2, and the obtuse angle formed between the bristles 42 and the horizontal plane is approximately 141°. When the spray bar 2 extends, the front end of the spray bar 2 pushes up the cover 3, the cover 3 flips upward and opens, and the cleaning brush 4 moves upward with the cover 3. When the spray bar 2 extends to the point that the cover 3 is fully open, the cleaning brush 4 is located above the spray bar 2, and its bristles 42 begin to contact the upward-facing outer surface of the spray bar 2. Under the weight of itself and the cover 3, the cleaning brush 4's bristles 42 adhere to the outer surface of the spray bar 2, as shown. Figure 5 , Figure 6 As shown, as the spray bar 2 continues to extend forward, the bristles 42 of the cleaning brush 4 slide and rub against the outer surface of the spray bar 2, thereby brushing the outer surface of the spray bar 2, as shown. Figure 7As shown. After the spray bar 2 completes the rinsing function, it retracts. During the retraction process, the bristles of the cleaning brush 4 slide and rub against the outer surface of the spray bar 2 again, thereby brushing the outer surface of the spray bar 2 with water again, as shown. Figure 8 As shown. Therefore, in conventional rinsing applications, the cleaning brush 4 can automatically perform two brushing and cleaning operations on the outer surface of the spray bar 2 each time. In addition to conventional rinsing applications, a self-cleaning program can be set to make the spray bar 2 extend and retract back and forth when the self-cleaning program is activated, thereby allowing the cleaning brush 4 to brush the outer surface of the spray bar 2. During the brushing process of the cleaning brush 4 on the spray bar 2, the rinsing component of the present invention can also activate the self-cleaning rinsing function, causing water to exit from the self-cleaning hole provided on the fixing base 1 to spray water onto the outer surface of the spray bar 2, promptly rinsing away the dirt brushed off by the cleaning brush 4, thereby improving the cleaning effect on the outer surface of the spray bar 2.

[0044] This invention discloses a toilet spray bar self-cleaning device that cleans the outer surface of the spray bar 2 by brushing or scraping. Compared with the existing flushing self-cleaning method, it is more effective in removing dirt adhering to the outer surface of the spray bar 2, thereby greatly improving the cleaning effect. In particular, this invention sets the cleaning component (i.e., the cleaning brush 4) on the cover 3. On the one hand, the cover 3 can be used to improve the overall aesthetics and protect the spray bar 2. On the other hand, it makes the disassembly and assembly of the cleaning component more convenient. When it is necessary to disassemble or assemble the cleaning component, simply flip up the cover 3 to expose the cleaning component, thus achieving visible disassembly and assembly.

[0045] Example 2

[0046] Please see Figure 9 As shown, the toilet spray bar self-cleaning device of the present invention differs from the above-described embodiment 1 in that the cleaning component further includes a pre-tightening member. This pre-tightening member provides a pre-tightening force to the cleaning component and / or the cover 3 when the cleaning component contacts the outer surface of the spray bar 2, thereby ensuring that the cleaning component adheres tightly to the outer surface of the spray bar 2. Therefore, the present invention further incorporates a pre-tightening member on top of the above-described method of relying on gravity to ensure the cleaning component adheres tightly to the outer surface of the spray bar 2, thereby increasing the degree of adhesion between the cleaning component and the outer surface of the spray bar 2, and further improving the brushing or scraping effect of the cleaning component.

[0047] In this embodiment, the cleaning component is also a cleaning brush 4, but it is not limited to this. The pre-tightening component only activates its pre-tightening function when the cover 3 is at a specific opening angle, which reduces the running resistance of the spray bar 2 in its normal state. That is, the pre-tightening component only activates its pre-tightening function when the cover 3 is opened to the point where the cleaning brush 4 falls onto the outer surface of the spray bar 2, and there is no pre-tightening function during the process of the spray bar 2 pushing the cover 3 to flip open, so that the running resistance of the spray bar 2 at the beginning of its extension is small.

[0048] In this embodiment, the preload element is an elastic element, which is tensioned between the drive element and the mounting element (i.e., the outer cover 5). Specifically, the elastic element is a torsion spring 7, but it is not limited to this. The torsion spring 7 is fitted outside the pivot 6 of the cover 3, and its two legs abut against the cover 3 and the outer cover 5 respectively.

[0049] The self-cleaning device for a toilet spray bar according to the present invention has a self-cleaning process roughly as described in Embodiment 1, and will not be repeated here.

[0050] The present invention discloses a self-cleaning method for a toilet spray bar, which uses a cleaning component to clean the toilet spray bar 2. The cleaning component includes a driving component and a cleaning component. When cleaning is started, the driving component drives the cleaning component to a state of contact with the outer surface of the spray bar 2, and scrapes or brushes the outer surface of the spray bar 2 as the spray bar 2 extends or retracts. When cleaning is finished, the driving component drives the cleaning component away from the outer surface of the spray bar 2 component.

[0051] In this embodiment, the driving component includes a cover 3 that can be flipped up and down. When the spray bar 2 is retracted, the cover 3 covers the front side of the spray bar 2. When cleaning is started, the spray bar 2 extends and pushes the cover 3, causing the cover 3 to flip up and open, bringing the cleaning component into contact with the outer surface of the spray bar 2. In other embodiments, the cleaning component is located above the spray bar 2. When cleaning is required, the driving component moves the spray bar 2 downward to contact the outer surface of the spray bar 2, so as to facilitate scraping or brushing the outer surface of the spray bar 2. The driving component is driven by a separately provided power component. In this way, the cleaning component can be prevented from contacting the outer surface of the spray bar 2 when the spray bar 2 is performing its normal rinsing function, thus avoiding increasing the normal operating resistance of the spray bar 2.

[0052] In this embodiment, the cleaning component is a cleaning brush 4, but it is not limited to this. In other embodiments, the cleaning component is a scraper. During the cleaning process of the spray bar, the cleaning component can activate the self-cleaning function of the rinsing assembly, so that the present invention can simultaneously use the cleaning component to brush or scrape the outer surface of the spray bar while spraying water on the outer surface of the spray bar, thereby improving the cleaning effect on the outer surface of the spray bar.

[0053] The present invention provides a self-cleaning method for a toilet spray bar, which can be implemented using the above-described embodiment one or embodiment two. The detailed self-cleaning method is described above and will not be repeated here.

[0054] The present invention provides an intelligent toilet seat, comprising a toilet spray bar self-cleaning device as described in any of the above embodiments.

[0056] The toilet spray bar self-cleaning device and method and smart toilet seat of the present invention, the parts not covered (such as the structure and working principle of the drive mechanism of the flushing component, etc.) are the same as or can be implemented by existing technology.

[0057] The above embodiments are only used to further illustrate a toilet spray bar self-cleaning device and method and a smart toilet seat of the present invention. However, the present invention is not limited to the embodiments.
