Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a toilet cleaning device and a toilet. Background Technology

[0002] Before use, the toilet bowl surface should be dry. Since toilets are generally made of ceramic, a dry ceramic surface is prone to staining and difficult to clean. Furthermore, after use, residue may remain on the toilet bowl, creating a breeding ground for bacteria. Therefore, current toilet technology employs either a pre-wetting mechanism with a bidet wash or a separate spray system for pre-wetting or disinfecting.

[0003] For pre-wetting, there are many existing solutions. For example, Chinese patent CN201810367851.8 proposes a pre-wetting nozzle for a smart toilet. This nozzle uses centrifugal force to create a mist-like spray of water as it flows outwards, colliding with each other to pre-wet the toilet. This method consumes less water and provides good cleaning results. Another example is Chinese patent CN201710118083.8, which proposes a sterilizing water spray device and a bidet equipped with it. This spray device can move back and forth in a straight line and spray sterilizing water into the toilet bowl. Furthermore, multiple nozzles arranged in four directions rotate and spray sterilizing water. Therefore, sterilizing water can be sprayed evenly throughout the toilet bowl, improving its sterilization ability. Yet another example is the toilet sterilizer disclosed in Korean patent KR101569910B1, which provides a clean and comfortable bathroom by evenly spraying sterilizing water supplied from a sterilizing water generation unit onto the inner surface of the ceramic object to be cleaned and sterilized. While the aforementioned existing technologies can pre-wet or disinfect toilet bowl surfaces 360°, they generally suffer from the following problems:

[0004] If the pre-wetting or disinfection requirements of the far end of the toilet bowl are met, the water flow near the toilet bowl will be too large, which will easily cause splashing around the perimeter, resulting in secondary pollution and affecting the user experience. If the water pressure is reduced, although the pre-wetting or disinfection requirements of the near end of the toilet bowl are met, the water flow cannot reach the far end of the toilet bowl, and the pre-wetting or disinfection requirements cannot be met. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a toilet cleaning device and toilet, which can adjust the water output according to the change of water spray position, ensuring cleaning effect while reducing water splashing.

[0006] The technical solution adopted by this invention to solve its technical problem is: a toilet cleaning device, comprising:

[0007] The water spray module is used to spray water onto the toilet bowl surface and is designed to rotate to clean different positions on the toilet bowl surface in the circumferential direction.

[0008] A water flow switching module is connected to the water spray module to supply water to the water spray module, and is configured to switch the water flow as the water spray module rotates, so that the water spray module can adapt to different water flow according to the change of its spray position.

[0009] The drive module is configured to control the rotation of the water spray module and control the water flow switching module to perform switching actions.

One of the first component and the second component is connected to the water spray module. The first component or the second component is driven by the drive module to connect the water outlet with different parts of the drainage structure.

[0011] Furthermore, the drainage structure is a gradually changing waterway, the width of which gradually changes along its extension direction.

[0012] Furthermore, the gradient waterway is a ring-shaped gradient waterway, the width of which is gradually changing along its circumference, and the part with the largest width is opposite to the part with the smallest width; the first component or the second component is driven to rotate by the driving module, and the first component and the second component are rotatably connected.

[0013] Furthermore, the first component is a water inlet portion, which has a water inlet connected to the drainage structure; the second component is a switching component, which is connected to the water spray module and driven by the drive module; the water inlet portion includes a housing portion and a valve plate disposed in the housing portion, which forms the gradual water channel with the housing portion; the valve plate is abutted against the top surface of the switching component by an elastic element.

[0014] Furthermore, the drive module includes a motor and a transmission assembly, wherein the motor is connected to the first or second component of the water spray module and / or the water flow switching module via the transmission assembly.

[0015] Furthermore, the transmission assembly includes a driving gear and a driven gear. The driving gear is connected to the output shaft of the motor. The first component or the second component is integrally formed or fixedly connected to the driven gear and fixedly connected to the injection module. The driven gear meshes with the driving gear.

[0016] Furthermore, the housing portion includes an upper cover and a water inlet body with the water inlet, the water inlet body being connected to the upper cover, and the two forming an inner cavity of the water inlet portion; the upper cover is connected to a bottom shell, and the two forming an accommodating cavity for accommodating the transmission assembly and the switching component.

[0017] Furthermore, the water spray module includes a spray bar and a universal nozzle, the universal nozzle being mounted at the water outlet end of the spray bar with an adjustable water outlet angle; the universal nozzle includes an inlet ball head and a water outlet part that are interconnected, the inlet ball head being connected to the spray bar.

[0018] Furthermore, the water outlet is provided with a fan-shaped water outlet structure, so that the water outlet outputs fan-shaped sheet-like water sprays, and the fan-shaped sheet-like water sprays are located on the vertical surface.

[0019] Furthermore, the water outlet surface of the water outlet is inclined, and the water outlet is provided with multiple water outlet holes. These multiple water outlet holes are arranged in at least one row along the inclined direction of the water outlet surface, and the diameter of each row of water outlet holes gradually increases from high to low along the arrangement direction.

[0020] Furthermore, the water inlet ball head is equipped with a water distribution component to ensure that the water flow enters the universal nozzle evenly; and / or, the water inlet ball head is locked to the water outlet end of the spray bar by a fixing seat, and the fixing seat is threadedly connected to the spray bar.

[0021] Furthermore, when the water spray module rotates and sprays water from the rear wall to the front wall of the toilet bowl, the water output of the water spray module gradually increases; when the water spray module rotates and sprays water from the front wall to the rear wall of the toilet bowl, the water output of the water spray module gradually decreases.

[0022] The present invention also provides a toilet, including a toilet body and a toilet cleaning device as described above, wherein the toilet cleaning device is installed at the rear top of the toilet body.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The toilet cleaning device of the present invention includes the spray module, the water flow adjustment module, and the drive module. It can not only automatically change the spray position to achieve 360° comprehensive cleaning of the toilet bowl, but also adjust the water output of the spray module according to the change of the spray position, so that the spray module adapts to the appropriate water output according to the change of its spray position, thereby making the cleaning water speed different for different parts of the toilet bowl, avoiding the problem of secondary splashing and pollution caused by excessive water speed during cleaning.

[0025] 2. The drainage structure is a gradually changing water path, the width of which gradually changes along its extension direction, thereby achieving linear stepless adjustment and ensuring stable water output without significant fluctuations. Specifically, the gradually changing water path is preferably a ring-shaped gradually changing water path. The switching element is rotatably connected to the water inlet section, allowing the switching element and the spray module to rotate simultaneously. This makes it easier for the drive module to control both the switching element and the spray module simultaneously, and also simplifies the design of the drive module.

[0027] 4. The water spray module includes the spray bar and the universal nozzle, which can adjust the water outlet angle, so that the present invention can be adapted to toilet bowl surfaces with different curvatures, thereby greatly improving the versatility of the present invention.

[0028] 5. The water outlet of the universal nozzle is provided with a fan-shaped water outlet structure, which enables the water outlet to output fan-shaped water spray, thereby achieving a faster and larger area cleaning effect.

[0029] 6. The water outlet section is provided with multiple water outlet holes, which are arranged in at least one row along the inclined direction of the water outlet surface. The diameter of each row of water outlet holes gradually increases from high to low along the arrangement direction, so that the water pressure of the spray module of the present invention is different at different distances from the same spray position on the toilet bowl surface, thereby further reducing the problem of water splashing during washing.

[0030] 7. The universal nozzle is locked to the spray bar with a fixed base, making the universal nozzle detachable and enabling quick disassembly, cleaning, or replacement.

[0031] 8. The water inlet ball head is equipped with a water distribution component, which can make the water flow evenly into the universal nozzle.

Therefore, "one embodiment" or "another embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0050] Please see Figures 1-11 As shown, a toilet according to the present invention includes a toilet body 6 and a toilet cleaning device, the toilet cleaning device being installed on the top rear part of the toilet body 6. Specifically, the toilet is a smart toilet; therefore, the toilet cleaning device is specifically installed on a base 7 at the rear of the toilet body 6.

[0051] The toilet cleaning device includes a water spray module 1 and a water flow switching module 2. The water spray module 1 sprays water onto the toilet bowl surface and is rotatable to clean different circumferential positions of the toilet bowl surface. The water flow switching module 2 connects to the water spray module 1 to supply water to it. As the water spray module 1 rotates, the water flow switching module 2 switches the water flow, allowing the water spray module 1 to adapt to different water outputs according to its spraying position. Specifically, when the water spray module 1 rotates from the back wall to the front wall of the toilet bowl surface to spray water, the water output gradually increases; conversely, when the water spray module 1 rotates from the front wall to the back wall of the toilet bowl surface to spray water, the water output gradually decreases. The toilet cleaning device also includes a drive module configured to control the rotation of the water spray module 1 and control the water flow switching module 2 to perform the switching action.

[0052] The water flow switching module 2 includes a first component and a second component. The first component has a drainage structure with different water flow rates at different parts. The second component has a water inlet 251. One of the first and second components is connected to the spray module. The first or second component is driven by the drive module, causing the water inlet 251 to connect to different parts of the drainage structure. Specifically, the second component is connected to the spray module (i.e., the water inlet 251 of the second component connects to the water inlet of the spray module 1), but this is not limited to this. In other embodiments, the first component is connected to the spray module (i.e., the drainage structure of the first component connects to the water inlet of the spray module). The first and second components are movably connected, and the second component is driven by the drive module, while the first component is fixedly set. However, this is not limited to this. In other embodiments, the first component is driven by the drive module, and the second component is fixedly set.

[0053] The aforementioned drainage structure is a gradient waterway, the width of which gradually changes along its extension direction. In other embodiments, the drainage structure includes a plurality of drainage holes arranged along a preset direction, the diameters of which are different. Specifically, the plurality of drainage holes are arranged in descending order of their diameter, or in descending order of their diameter, or first arranged in ascending order and then in descending order of their diameter.

[0054] The gradient waterway is specifically an annular gradient waterway 28, the width of which gradually changes along its circumference, and the widest part is opposite the narrowest part (i.e., the widest part is located on the same radial direction as the narrowest part). The second component is driven to rotate by the drive module, and the second component is rotatably connected to the first component.

[0055] The first component is a water inlet section, which has a water inlet 211 connected to the drainage structure. The second component is a switching element 25, which is connected to the water spray module 1 and is driven to rotate by the drive module. As the switching element 25 rotates, the water outlet 251 moves along the annular gradient water channel 28, thereby connecting with different parts of the annular gradient water channel 28. The water inlet section includes a housing part and a valve plate 24 disposed within the housing part. The valve plate 24 and the housing part form the annular gradient water channel 28. The valve plate 24 is abutted against the top surface of the switching element 25 by an elastic element 23. The elastic element 23 is specifically a spring, but is not limited to this.

[0056] The drive module includes a motor 3 and a transmission assembly. The motor 3 is connected to the first or second component of the water spray module 1 and / or the water flow switching module 2 via the transmission assembly. Specifically, the motor 3 is connected to the water spray module 1 and / or the second component (i.e., the switching element 25) via the transmission assembly. The transmission assembly includes a drive gear 4 and a driven gear 5. The drive gear 4 is connected to the output shaft of the motor 3. The driven gear 5 is integrally formed or fixedly connected to the second component (i.e., the switching element 25) and meshes with the drive gear 4. The switching element 25 is sealed and fixedly connected to the water spray module 1. Specifically, the two are fixedly connected by a threaded connection and a sealing ring is provided.

[0057] The housing includes an upper cover 22 and a water inlet body 21 with the water inlet 211. The water inlet body 21 is connected to the upper cover 22, and the two together form the inner cavity of the water inlet section. The switching element 25 is sealed to the upper cover 22 with a V-shaped sealing ring 27. Specifically, the water inlet body 21 is fixedly connected to the upper cover 22 with screws 212, and a sealing ring is fitted between the two. The upper cover 22 is connected to a bottom shell 26 with screws 221, and the two together form a receiving cavity for accommodating the transmission assembly and the switching element 25. The motor 3 is fixed to the upper cover 22 with screws 31. The water spray module 1 passes through the bottom shell 26.

[0058] The water spray module 1 includes a spray bar 11 and a universal nozzle 13. The universal nozzle 13 is mounted at the water outlet end of the spray bar 11 with an adjustable water outlet angle. The universal nozzle 13 includes an inlet ball head 131 and a water outlet section 132 that are interconnected. The inlet ball head 131 is connected to the spray bar 11. The inlet ball head 131 is locked to the water outlet end of the spray bar 11 by a fixing seat 14. The fixing seat 14 is threadedly connected to the spray bar 11. Specifically, the fixing seat 14 has a through-type structure at both ends, and one end is provided with an internal thread (or it can also be an external thread). The other end has a constricted port. During assembly, the universal nozzle 13 is first inserted into the fixing seat 14 from one end, and the water outlet section 132 of the universal nozzle 14 passes through the port at the other end of the fixing seat 14. Then, the internal thread at one end of the fixing seat is screwed into the external thread provided at the water outlet end of the spray bar 11. At this time, the inlet ball head 131 is located inside the fixed seat 14, and to ensure a sealing effect, a sealing ring can be used to fit the gap between the inlet ball head 131 and the fixed seat 14. When it is necessary to adjust the water outlet angle of the universal nozzle 13, first loosen the fixed seat 14, then rotate the water outlet part 132 to rotate the universal nozzle 14 to a suitable water outlet angle, and then lock the fixed seat 14 in this state. In this way, the water outlet angle of the universal nozzle 13 can be adjusted.

[0059] In one exemplary embodiment, the water outlet 132 is provided with a fan-shaped water outlet structure 1321, so that the water outlet 132 outputs fan-shaped sheet-like water sprays, such as... Figure 5 , Figure 6 As shown, the fan-shaped water spray is located on a vertical surface, thereby achieving a faster and larger area cleaning effect. The fan-shaped water outlet structure 1321 specifically includes a spherical crown surface disposed within the water outlet section 132 and a V-shaped groove disposed on the water outlet surface of the water outlet section 132, the V-shaped groove being tangent to the spherical crown surface.

[0060] The water inlet ball head 131 is equipped with a water distribution component 12 to ensure that the water flows evenly into the universal nozzle 13.

[0061] The spray bar 11 includes a vertical section and an inclined section. The bottom end of the vertical section and the top end of the inclined section are integrally formed, and the bottom end of the inclined section constitutes the water outlet.

[0062] During installation of the toilet cleaning device, a mounting hole is provided on the base 7 at the top rear of the toilet body 6. The bottom shell 26 and / or the top cover 22 are fixed to the base 7, and the spray bar 11 passes downward through the mounting hole. Figure 7 , Figure 8 As shown, the widest part of the annular gradient water channel 28 should face the front of the toilet body 6, and the narrowest part should face the rear of the toilet body 6; adjust the water outlet angle of the universal nozzle 13 to match the curvature of the toilet bowl surface. After installation, connect the water inlet 211 of the water inlet section to the water inlet control system 8 through the antibacterial water generator 10, water pipes, etc., and electrically connect the motor 3 to the main control board 9 of the toilet. After that, water can be turned on for testing.

[0063] After the system starts, the main control board 9 controls the motor 3 to rotate forward or backward 360°. The water inlet 251 of the switching component 25 moves from position ① (the narrowest position) of the annular gradual water channel 28 to position ②, then to position ③ (the widest position), and finally back to position ①. Figure 9 As shown, during this process, the water from the water spray module 1 increases linearly from position ①, and begins to decrease linearly when it reaches position ③. Positions ①, ②, ③, and ④ on the annular gradient water path 28 correspond to the following... Figure 10 The water spray module 1 shown has spray positions ①, ②, ③, and ④ on the toilet bowl surface. Each spray position ①, ②, ③, and ④ is a 50° angle range centered on the center of the toilet bowl surface, roughly corresponding to the middle of the front, back, left, and right walls of the toilet bowl. Therefore, as the water spray module 1 rotates to different spray positions on the toilet bowl surface, its water output changes linearly, with the lowest water output at spray position ① and the highest at spray position ③. Figure 11 As shown. Therefore, this invention causes the water spray module 1 to generate different water volumes at different spray positions when the water sprays out and rotates, thereby making the washing water speed different at different positions in the circumferential direction on the toilet bowl surface, avoiding the problem of secondary splashing and contamination caused by excessive water speed during washing. At the same time, the omnidirectional nozzle 13 outputs vertical fan-shaped water sprays, achieving the effect of rapid sterilization and wetting of the toilet bowl surface.

[0064] Please see Figure 12 , Figure 13 As shown, in another exemplary embodiment, the water outlet surface of the water outlet 132 is inclined, and the water outlet 132 is provided with a plurality of water outlet holes 1321. The plurality of water outlet holes 1321 are arranged in at least one row along the inclined direction of the water outlet surface, and the diameter of each row of water outlet holes 1321 gradually increases from high to low along the arrangement direction.

[0065] Preferably, the number of water outlet holes 1321 is four, but not limited to this, and the four water outlet holes 1321 are arranged in a row. The diameter of the four water outlet holes 1321 gradually increases from high to low along their arrangement direction, so that the water velocity and spray distance gradually decrease from top to bottom. When the water reaches the toilet bowl surface, it can cover the cross section of the toilet bowl surface as quickly as possible, achieving a rapid wetting and cleaning effect. At the same time, due to the different water velocities formed by the different hole diameters, the splashing problem during the cleaning and wetting process is effectively reduced.

[0066] The present invention provides a toilet cleaning device and a toilet, the parts of which are not described herein are the same as or can be implemented using existing technology.

[0067] The above embodiments are only used to further illustrate a toilet cleaning device and toilet of the present invention. However, the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations 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.
