Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to a cleaning nozzle, a spray bar assembly, and a toilet. Background Technology

[0002] As people's living standards improve, the demand for smart toilets is also increasing, and they are increasingly fond of the diversification of smart toilet functions. Currently, the common cleaning functions of smart toilets are posterior washing and feminine washing, and the cleaning nozzle usually has two corresponding water outlets. If one or more cleaning modes are added, more water outlets need to be added to the cleaning nozzle to diversify the cleaning modes and meet the needs of more people.

[0003] Currently, smart toilets feature dynamic water washing functions in their cleaning nozzles to provide users with a better cleaning experience. This is primarily achieved through either a built-in dynamic mechanism or an external linkage mechanism to achieve a wide-range dynamic water flow. The built-in dynamic mechanism uses gravity and water pressure to cause it to oscillate within the channel, resulting in a wide-range water flow. While some solutions use external linkage mechanisms, both methods are structurally complex, difficult to manufacture and assemble, and costly. In particular, the built-in dynamic mechanism is prone to jamming after prolonged use due to scale buildup, leading to poor or no dynamic water flow, thus affecting user experience. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of existing technologies that use dynamic structures to achieve wide water flow from nozzles. This invention proposes a cleaning nozzle, spray bar assembly, and toilet, in which a guide block is set in the water outlet of the nozzle to change the direction of part of the water flow, thereby forming a wide cleaning water flow and increasing the cleaning area. The invention is simple in structure and low in cost.

[0005] The present invention adopts the following technical solution:

[0006] A cleaning nozzle device includes a water outlet body with a water outlet channel, the water outlet channel having a water cavity and a water outlet hole. The device is characterized by further including a guide block, the guide block being disposed within the water cavity and having a water passage hole connecting the water outlet hole and the water cavity. Two guide blocks are also disposed on the inner wall of the water outlet hole, the two guide blocks being centrally symmetrically arranged in the radial direction of the water passage hole and forming an acceleration zone. Each guide block has a first guide surface and a protrusion on its side facing the guide block, and a second guide surface on the side of the protrusion opposite the guide block. The guide blocks guide a portion of the water flow in the radial direction towards the other guide block, tilting it into the acceleration zone. The two portions of water flow guided by the two guide blocks, after acceleration, flow towards the water outlet hole near the outlet end and merge to output a wide-range cleaning water.

[0007] The protrusion extends towards the side where the water passage is located along the axial direction of the water outlet relative to the first guide surface. In the axial direction, the distance from the first guide surface to the corresponding end face of the guide block is greater than the distance from the second guide surface to the corresponding end face of the guide block. This causes the partial water flow to split into two streams with different flow rates and enter the acceleration zone. After acceleration, the multiple streams split from the two partial water flows are output from the water outlet as oscillating, wide-range cleaning water.

[0008] In the axial direction, the ratio of the distance from the first guide surface to the corresponding end face of the guide block to the distance from the second guide surface to the corresponding end face of the guide block is greater than or equal to 1.2 and less than or equal to 3.

[0009] The flow guide block is configured as a plane on the side opposite to the guide block. In the axial direction, the ratio of the distance from the plane to the water outlet end face of the water outlet hole to the distance from the plane to the second flow guide surface is greater than or equal to 1.

[0010] The guide block is also provided with a third guide surface, which is formed on the protrusion and adjacent to the first guide surface and the second guide surface. The third guide surface extends radially to guide part of the water flow to flow into the acceleration zone at an angle in a radial manner and accelerate to form a vortex. The vortices guided by the two guide blocks converge to form particulate water splashes, so that the water outlet outputs a wide range of cleaning water with particulate water splashes and vortices.

[0011] The third guiding surface is an inclined surface; or the third guiding surface is an arc surface, with the third guiding surface of one guiding block being a convex arc and the third guiding surface of the other guiding block being a concave arc.

[0012] The guide block is disposed on the side of the water outlet in the water cavity, and the water passage hole and the water outlet hole are coaxially arranged; the ratio of the axial dimension of the water passage hole to the radial dimension of the water passage hole is greater than or equal to 2.

[0013] The two guide blocks are spaced apart in the radial direction to form the acceleration zone, which is located in the area between the side of the guide block opposite to the guide block and the side of the first guide surface; the ratio of the radial dimension of the acceleration zone between the two guide blocks to the radial dimension of the water passage is less than or equal to 1.1.

[0014] The two first guiding surfaces of the two guide blocks are centrally symmetrical in the radial direction, and the first guiding surface is an inclined surface or an arc surface; the two second guiding surfaces of the two guide blocks are centrally symmetrical in the radial direction, and the second guiding surface is an inclined surface or an arc surface.

[0015] The water outlet is provided with at least one water outlet channel, wherein one of the water outlet channels is provided with the guide block and the flow guide block to output the wide-range cleaning water.

[0016] A spray bar assembly includes a spray bar body, characterized in that: the spray bar body is provided with the aforementioned cleaning nozzle device.

[0017] A toilet includes a toilet body, characterized in that: the toilet body is provided with the aforementioned spray bar assembly.

[0018] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this invention, a guide block is set in the water cavity of the water outlet channel to make the water flow smoothly into the water outlet hole; two centrally symmetrical guide blocks are also set on the inner wall of the water outlet hole. Each guide block is provided with a first guide surface and a protrusion. A second guide surface is provided on the protrusion. The guide block guides part of the water flow to flow into the acceleration zone at an incline towards the other guide block through the first guide surface and the second guide surface. The two parts of water flow guided by the two guide blocks flow to the water outlet hole after acceleration and merge to output a wide range of cleaning water. The cleaning water between the two guide blocks maintains the cleaning force and merges with the wide range of cleaning water to increase the cleaning area. The structure is simple and the cost is low.

[0020] 2. In this invention, the protrusion extends axially toward the side where the water hole is located relative to the first guide surface. In the axial direction, the distance from the first guide surface to the corresponding end face of the guide block is greater than the distance from the second guide surface to the corresponding end face of the guide block, and the ratio of the two can be within a set range. This allows some of the water flow to be divided into two streams with different flow rates and enter the acceleration zone. After acceleration, the multiple streams of water divided into two parts are output from the water outlet as a wide-range oscillating cleaning water, which is more conducive to cleaning and less likely to cause stinging sensation.

[0021] 3. In this invention, the side of the guide block facing away from the guide block is set as a plane. In the axial direction, the ratio of the distance from the plane to the end face of the water outlet hole to the distance between the plane and the second guide surface is greater than or equal to 1, so that the water outlet angle of the water outlet hole is effectively controlled within the cleaning range.

[0022] 4. In this invention, a third guiding surface is provided on the protrusion of the guide block. The third guiding surface is adjacent to the first guiding surface and the second guiding surface and extends radially to guide part of the water flow to flow into the acceleration zone in a radial manner and accelerate to form a vortex. The vortices guided by the two guide blocks converge to form particulate water splashes, so that the water outlet outputs a wide range of cleaning water with particulate water splashes and vortices, resulting in better cleaning effect and better experience.

[0023] 5. In this invention, the first guide surface, the second guide surface and the third guide surface can be inclined surfaces or arc surfaces. The forming process of the guide block in the water outlet hole is simple, and the output dynamic wide-range cleaning water is stable and durable. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0041] The present invention will be further described below through specific embodiments.

[0042] In this invention, the terms "first," "second," and "third," etc., are used only to distinguish similar objects and are not necessarily used 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.

[0043] Furthermore, in the description of this application, unless otherwise stated, "multiple" means 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.

[0044] See Figures 1 to 10 A cleaning nozzle device includes a water outlet body 10, which has at least one water outlet channel 20. Each water outlet channel 20 may have a water cavity 21 and a water outlet hole 22. Multiple water outlet channels 20 are independent of each other and can be used to realize different water outlet functions, such as posterior washing, feminine washing, or other cleaning functions. In this invention, a guide block 30 is provided in one of the water outlet channels 20. The guide block 30 is disposed in the water outlet cavity 21 of the water outlet channel 20 and has a water passage hole 31. The water passage hole 31 connects the water outlet hole 22 and the water cavity 21 of the water outlet channel 20. The cleaning water entering the water cavity 21 of the water outlet channel 20 must pass through the water passage hole 31 to enter the water outlet hole 22.

[0045] The guide block 30 is located on the side of the water outlet 22 within the water cavity 21. The water passage 31 and the water outlet 22 are coaxially arranged, and the ratio of the axial dimension to the radial dimension of the water passage 31 is greater than or equal to 2. The radial dimension of the water outlet 22 is also smaller than the radial dimension of the water cavity 21. This arrangement ensures that the cleaning water entering the water cavity 21 flows smoothly and steadily into the water outlet 22. The guide block 30 may have protrusions 32 on its outer periphery, and corresponding grooves are provided within the water cavity 21. The guide block 30 is fixed by the protrusions 32 embedding into the corresponding grooves. The number of protrusions 32 can be set according to actual needs, and can be one, two, or even three, etc. The number of grooves corresponds to the number of protrusions 32; the specific number is not limited here.

[0046] The present invention further includes two guide blocks 40 on the inner wall of the water outlet 22. The two guide blocks 40 are centrally symmetrically arranged in the radial direction of the water passage 31, and are radially spaced to form an acceleration zone 41. The radial dimension of the acceleration zone 41 is smaller than the size of the water passage 31, thereby accelerating the water flow. This acceleration zone 41 can be located in the area near the water outlet end of the water outlet 22 between the two guide blocks 40. Each guide block 40 has a first guide surface 42 and a protrusion 43 on the side facing the guide block 30. A second guide surface 44 is provided on the side of the protrusion 43 opposite to the guide block 30, so both the first guide surface 42 and the second guide surface 44 face the guide block 30. The cleaning water flowing out of the guide block 30 flows towards the first guide surface 42, the second guide surface 44 on the two guide blocks 40, and between the two guide blocks 40. The guide block 40 guides a portion of the water flow radially toward the other guide block 40 and into the acceleration zone 41 via the first guide surface 42 and the second guide surface 44. After acceleration, the two portions of water flow guided by the two guide blocks 40 flow toward the outlet hole 22 near the outlet end and merge to output a wide range of cleaning water. The remaining cleaning water flow between the two guide blocks 40 maintains its cleaning force and merges with the wide range of cleaning water on both sides to ensure a large cleaning area.

[0047] The acceleration zone is located between the two guide blocks 40 and the surface of the guide block 40 facing away from the guide block 30 to the surface of the first guide surface 42. The ratio of the radial dimension W1 of the acceleration zone 41 between the two guide blocks 40 to the radial dimension D1 of the water passage hole 31 is less than or equal to 1.1.

[0048] The guide block 40 is configured as a plane 56 on the side facing away from the guide block 30, meaning the water outlet end face of the guide block 40 is configured as plane 56. In the axial direction, the ratio of the distance H1 from plane 56 to the water outlet end face of the water outlet hole 22 to the distance H2 between plane 56 and the second guide surface 44 is greater than or equal to 1. By setting the ratio of H1 and H2 within this range, the water outlet angle of the nozzle device is effectively controlled within the set cleaning range.

[0049] Furthermore, the two first guide surfaces 42 of the two guide blocks 40 are radially symmetrical. The first guide surface 42 is an inclined surface or an arc surface, which guides part of the water flow in the radial direction towards the other guide block 40 and into the acceleration zone 41. The two second guide surfaces 44 of the two guide blocks 40 are radially symmetrical. The second guide surface 44 is an inclined surface or an arc surface, which guides part of the water flow in the radial direction towards the other guide block 40 and into the acceleration zone 41. If the first guide surface 42 or the second guide surface 44 is an arc surface, the arc surface is a convex arc. If the first guide surface 42 or the second guide surface 44 is an inclined surface, the inclined surface extends axially from the inner wall of the outlet hole 22 towards the outlet end face of the outlet hole 22.

[0050] Furthermore, since the protrusion 43 extends towards the side where the water outlet 22 is located relative to the first guide surface 42, the distance from the first guide surface 42 to the corresponding end face of the guide block 30 is greater than the distance from the second guide surface 44 to the corresponding end face of the guide block 30 in the axial direction. This causes part of the water flow to be divided into two streams with different flow rates and enter the acceleration zone 41. After acceleration, the multiple streams of water flow divided into two parts are output from the water outlet 22 as oscillating wide-range cleaning water.

[0051] Specifically, in the axial direction, the ratio of the distance H4 from the first guide surface 42 to the corresponding end face of the guide block 30 to the distance H5 from the second guide surface 44 to the corresponding end face of the guide block 30 is greater than or equal to 1.2 and less than or equal to 3. Limiting this ratio within this range ensures that the water flowing to the first guide surface 42 and the second guide surface 44 is split into two streams with different flow rates due to the volume difference, and each stream flows towards the acceleration zone 41 at a different inclination angle. The two streams of water from the two guide blocks 40, splitting into multiple streams with different flow rates and inclination angles, achieve a small-amplitude oscillation of the water flow. After acceleration, the oscillating, wide-range cleaning water is output from the outlet 22.

[0052] See Figure 10 In the cross-sectional view, the cross-sectional area of ​​position 2, which is at a distance from H5, is different from that of position 6 in different guide blocks. Therefore, the flow rate of the cleaning water to position 1 and position 2 is also different, so it is divided into different water streams, one with a large flow rate and the other with a small flow rate. The different water streams are then guided by the first guide surface and the second guide surface respectively. The water flow at position 1 flows to position 4 through the acceleration zone 41, and the water flow at position 2 flows to position 3 through the acceleration zone 41. The water flows at positions 3 and 4 flow out through the water outlet 22 to form a wide-amplitude oscillating cleaning water.

[0053] Furthermore, the guide block 40 is also provided with a third guide surface 45, which is formed on the protrusion 43 and adjacent to the first guide surface 42 and the second guide surface 44. The third guide surface 45 extends radially to guide a portion of the water flow into the acceleration zone 41 at an angle in a radial manner and accelerates to form a vortex. The vortices guided by the two guide blocks 40 converge to form particulate water splashes, so that the outlet hole 22 outputs a wide-range cleaning water with particulate water splashes and vortices. Figure 13 and Figure 14 .

[0054] Specifically, the third guide surface 45 is an inclined surface that extends radially from the inner wall of the outlet hole 22. The inclination directions of the third guide surfaces 45 of the two guide blocks 40 can be different. Alternatively, the third guide surface 45 can be an arc surface, with one guide block 40 having a convex arc and the other guide block 40 having a concave arc. The third guide surface 45 guides the two parts of the water flow to flow radially and obliquely into the acceleration zone 41.

[0055] The water outlet body 10 of the present invention can be an integral structure or a split structure. Taking the split structure as an example, it includes a main body 11 and a cover 12. The main body 11 is provided with multiple water outlet channels 20 and can be provided with openings at each water cavity 21. The cover 12 is fixed to the opening of the main body 11 to close the opening end of each water cavity 21. The main body 11 is also provided with water inlet holes 23. Multiple water inlet holes 23 can be located at one end in the length direction of the main body 11 and communicate with the water cavity 21 of the corresponding water outlet channel 20.

[0056] Based on this, see Figure 11 The present invention also proposes a spray bar assembly, including a spray bar body 60, the spray bar body 60 being provided with the above-mentioned cleaning nozzle device, and one of the water outlet channels 20 of the water outlet body 10 adopting the structure having the above-mentioned guide block 30 and flow guide block 40 to output dynamic wide-range cleaning water, the dynamic wide-range cleaning water being oscillating wide-range cleaning water, which also has superimposed swirling and particulate water droplets, etc.

[0057] The spray boom body 60 may also include a housing 61 and a telescopic drive structure 62, etc. The housing 61 is fitted outside the water outlet body 10, and the telescopic drive structure 62 is connected to drive the housing 61 to drive the water outlet body 10 to extend or retract. The spray boom body 60 may also be provided with a switching mechanism, which connects different water inlets 23 to achieve different water output effects.

[0058] Referring to the figures, this invention also proposes a toilet, including a toilet body 70, which is provided with the aforementioned spray bar assembly. The specific structure of the spray bar assembly is as described in the above embodiments. Since this toilet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0059] The toilet body 70 can be configured as a smart toilet. The smart toilet has the aforementioned spray bar assembly, which provides users with functions such as posterior washing or feminine washing. One of the water outlet channels 20 is configured to output dynamic wide-range cleaning water. The dynamic wide-range cleaning water is an oscillating wide-range cleaning water. In conjunction with the extension and retraction of the spray bar assembly, it can achieve a dynamic wide-range cleaning effect in all directions, increasing the cleaning area. It also has swirling and particulate water spray.

[0060] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
