Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent toilet, and in particular to a nozzle device and an intelligent toilet. BACKGROUND

[0002] The intelligent toilet can be said to be a hot topic in the bathroom industry. The water washing replaces the toilet paper, which is the development trend of the bathroom in the future. The intelligent toilet is provided with a washing ring nozzle on the top rear side of the toilet bowl. When the washing ring nozzle discharges water, the water jet is sprayed forward and flows along the inner side of the toilet bowl to flush the inner side of the toilet bowl.

[0003] The washing ring nozzle comprises a pipe body, a ball head and a gland. The gland is installed on the pipe body, and the ball head is installed between the pipe body and the gland. The ball head can rotate freely relative to the pipe body within a certain range, so as to adjust the water spraying direction. The intelligent toilet will adjust the water spraying direction of the washing ring nozzle before leaving the factory, so as to ensure the washing effect of the washing ring nozzle.

[0004] In the related art, the front end of the ball head is provided with a nozzle part which protrudes from the gland, so as to facilitate the adjustment of the angle of the ball head relative to the pipe body. However, the protrusion of the nozzle part from the gland will increase the risk of accidental change of the angle of the ball head relative to the pipe body, and reduce the cleaning effect of the washing ring nozzle. For example, during the transportation of the intelligent toilet, the nozzle part is impacted or pressed by other parts or buffer parts placed in the toilet bowl, which causes the angle of the ball head relative to the pipe body to change accidentally. For another example, the nozzle part is accidentally touched during the cleaning of the intelligent toilet, which causes the angle of the ball head relative to the pipe body to change accidentally.

[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0040] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0041] Firstly, please refer to Figure 1 and Figure 2 This application provides a nozzle device 100, which includes a tube body 1, a ball head 2, and a cap 3. The tube body 1 is provided with a first fluid channel 111, and one end of the tube body 1 is provided with a mounting groove 112, which communicates with the first fluid channel 111. The ball head 2 is rotatably disposed in the mounting groove 112, and the ball head 2 is provided with a second fluid channel 21, which communicates with the mounting groove 112. The cap 3 is disposed on the tube body 1 and abuts against the side of the ball head 2 away from the tube body 1 to press the ball head 2 into the mounting groove 112.

[0042] For the aforementioned tube body 1, tube body 1 can be cylindrical, and the first fluid channel 111 is cylindrical. Tube body 1 can be a straight tube, a bent tube, or both. It is understood that the inner wall of the mounting groove 112 is spherical and adapts to the ball head 2. When the ball head 2 is tightly against the inner wall of the mounting groove 112, the outer surface of the ball head 2 is in sealed contact with the inner wall of the mounting groove 112, thereby sealingly connecting the second fluid channel 21 of the ball head 2 with the first fluid channel 111 through the mounting groove 112. The mounting groove 112 is hemispherical, and the depth of the mounting groove 112 along the axial direction of tube body 1 is equal to or less than the radius of the ball head 2. The first fluid channel 111 can connect to the bottom of the mounting groove 112.

[0043] The ball head 2 is spherical, and the second fluid channel 21 can be cylindrical. The ports at both ends of the second fluid channel 21 are used to connect with the first fluid channel 111 and to eject fluid, respectively. By rotating the ball head 2 relative to the tube body 1, the angle of the second fluid channel 21 relative to the tube body 1 can be changed, thereby changing the direction of the fluid ejection. The fluid can be a liquid, gas, etc., such as water or air.

[0044] The pressure cap 3 can be annular. The pressure cap 3 includes an annular curved surface 321 that is adapted to the ball head 2. The annular curved surface 321 is a spherical part and is adapted to the ball head 2. Thus, the contact surface between the annular curved surface 321 and the ball head 2 is annular, which is beneficial for stably pressing the ball head 2.

[0045] For the connection of the gland 3 and the pipe body 1, refer to Figures 2 to 4 for example, one end of the pipe body 1 is provided with a connecting wall 12 extending along the circumference of the pipe body 1; the gland 3 comprises a connecting portion 31 and an abutting portion 32 connected with each other, the connecting portion 31 extends along the circumference of the pipe body 1, and the connecting portion 31 is threadedly connected with the connecting wall 12; the abutting portion 32 abuts against the side of the ball head 2 away from the pipe body 1.

[0046] That is, the connecting portion 31 is annular, the connecting portion 31 is sleeved and threadedly connected with the connecting wall 12, the gland 3 can be disassembled and assembled on the pipe body 1 by screwing the connecting portion 31, and the ball head 2 can be conveniently rotated when the gland 3 is loosened, and the angle of the ball head 2 relative to the pipe body 1 can be fixed when the gland 3 is tightened. The annular curved surface 321 is located on the abutting portion 32. In other embodiments, the abutting portion 32 can comprise a plurality of abutting claws arranged at intervals along the circumference of the pipe body 1 and abutting against the side of the ball head 2 away from the pipe body 1.

[0047] It should be noted that in the related art, the annular curved surface 321 is usually located at the end of the gland 3 away from the pipe body 1, that is, the distance between the annular curved surface 321 and the end of the gland 3 away from the pipe body 1 is extremely small, and the side of the ball head 2 away from the pipe body 1 must protrude from the annular curved surface 321, so that the ball head 2 protrudes from the gland 3 along the axial direction of the pipe body 1; or the front end of the ball head 2 is provided with a nozzle portion directly protruding from the gland 3. However, the protrusion of the ball head 2 from the gland 3 increases the risk of accidental change of the angle of the ball head 2 relative to the pipe body 1, and reduces the cleaning effect of the nozzle device 100 (i.e. the washing ring nozzle in the background art). For example, during the transportation of the intelligent toilet, the nozzle portion is impacted or pressed by other parts or buffer parts placed in the bowl, causing the angle of the ball head 2 relative to the pipe body 1 to change accidentally; for another example, accidental touching of the nozzle portion during cleaning of the intelligent toilet causes the angle of the ball head 2 relative to the pipe body 1 to change accidentally.

[0048] To improve the above problems, in some embodiments, refer to Figures 2 to 4 along the axial direction of the pipe body 1, the ball head 2 is recessed in the gland 3. For example, the width of the gland 3 along the axial direction of the pipe body 1 is widened. Thus, the probability of contact of the ball head 2 by external objects can be reduced, and the risk of accidental change of the angle of the ball head 2 relative to the pipe body 1 can be reduced.

[0049] However, it will make the width of the gland 3 along the axial direction of the pipe body 1 too wide, for example, greater than the radius of the ball head 2. In further embodiments, refer to Figures 2 to 4, the connecting portion 31 surrounds the ball head 2 and the abutting portion 32 along the circumference of the pipe body 1, and the ball head 2 is recessed in the connecting portion 31 along the axis of the pipe body 1. That is, the ball head 2 is partially located in the cavity in the middle of the connecting portion 31, and the abutting portion 32 is located in the cavity in the middle of the connecting portion 31 and abuts against the ball head 2 in the cavity, so that the distance between the annular curved surface 321 and the end of the connecting portion 31 away from the pipe body 1 increases, that is, the ball head 2 moves towards the pipe body 1 relative to the connecting portion 31, which is beneficial to shorten the width of the connecting portion 31 along the axis of the pipe body 1.

[0050] It can be understood that the connecting wall 12 can be sleeved on the connecting portion 31, and the gland 3 is connected with the connecting wall 12 by screwing into the connecting wall 12, which can cause the gland 3 to be difficult to apply force. In some embodiments, referring to Figure 3 and Figure 4 , the connecting portion 31 is sleeved on the connecting wall 12 adjacent to one end of the pipe body 1, the end of the connecting portion 31 away from the pipe body 1 is connected with the end of the abutting portion 32 away from the pipe body 1, and the abutting portion 32 abuts against the ball head 2 adjacent to one end of the pipe body 1. That is, in the axial section of the gland 3, the connecting portion 31 and the abutting portion 32 form a "V" shape, so that along the radial direction of the pipe body 1, the connecting portion 31 and the abutting portion 32 clamp the opposite sides of the connecting wall 12, so that the outer peripheral surface of the connecting portion 31 is exposed, which is convenient for holding and applying force, and the abutting portion 32 does not affect the threaded connection between the connecting portion 31 and the connecting wall 12.

[0051] When the connecting portion 31 and the abutting portion 32 form a "V" shape, because the connecting wall 12 has a thickness, the connecting portion 31 and the abutting portion 32 have a dead angle where the connecting wall 12 cannot enter, which causes the width of the connecting portion 31 and the abutting portion 32 along the axis of the pipe body 1 to be too large. In some embodiments, referring to Figure 3 and Figure 4 , the gland 3 further comprises a ring portion 33, the outer edge of the ring portion 33 is connected with the connecting portion 31, and the inner edge of the ring portion 33 is connected with the abutting portion 32. By connecting the connecting portion 31 and the abutting portion 32 through the ring portion 33, the width of the connecting portion 31 and the abutting portion 32 along the axis of the pipe body 1 is shortened, for example, along the axis of the pipe body 1, the connecting portion 31 and the abutting portion 32 can be flush with the connecting wall 12 or slightly exceed a certain distance, and only the ring portion 33 is required to connect the connecting portion 31 and the abutting portion 32. Wherein, the ring portion 33 can be perpendicular to the axis of the pipe body 1.

[0052] In some embodiments, referring to Figures 2 to 4 , the outer periphery of the connecting portion 31 is provided with anti-skid ribs 311. It is beneficial to improve the problem that the connecting portion 31 is easy to slide when being screwed. The anti-skid ribs 311 can be linear protrusions and are arranged at intervals along the outer peripheral surface of the connecting portion 31. The cross section of the anti-skid ribs 311 can be semicircular, which is beneficial to reduce the discomfort of the user holding the connecting portion 31 and reduce the dirt accumulation dead angle.

[0053] In some embodiments, referring toFigures 2 to 4 The abutting portion 32 is cylindrical, and the distance between the inner wall of the abutting portion 32 and the axis of the tube body 1 gradually increases in the direction parallel to the axial direction of the tube body 1 and away from the tube body 1. That is, the abutting portion 32 is trumpet-shaped, which is beneficial to improve the problem that the fluid sprayed by the ball head 2 touches the abutting portion 32.

[0054] In some embodiments, referring to Figures 2 to 4 The ball head 2 is provided with a limiting rib 22 on the side away from the tube body 1. The limiting rib 22 protrudes from the spherical surface of the ball head 2 and surrounds the second fluid passage 21. The limiting rib 22 is used to prevent the ball head 2 from rotating when abutting against the gland 3. Since the limiting rib 22 surrounds the second fluid passage 21, when the limiting rib 22 abuts against the gland 3, the second fluid passage 21 is not blocked by the abutting portion 32, which is beneficial to improve the problem that the excessive rotation of the ball head 2 causes the second fluid passage 21 to be blocked by the abutting portion 32. In addition, when the abutting portion 32 is trumpet-shaped and when the limiting rib 22 abuts against the gland 3, the rotation angle of the central axis of the second fluid passage 21 relative to the axis of the tube body 1 is smaller than the taper of the abutting portion 32, so that the fluid sprayed by the second fluid passage 21 does not touch the abutting portion 32, which is beneficial to improve the problem that the excessive rotation of the ball head 2 causes the fluid sprayed by the second fluid passage 21 to touch the abutting portion 32.

[0055] In some embodiments, referring to Figures 2 to 4 When the limiting rib 22 abuts against the gland 3, the ball head 2 is spaced apart from the first fluid passage 111. When the ball head 2 is spaced apart from the first fluid passage 111, the edge of the port of the second fluid passage 21 does not rotate into the first fluid passage 111, which is beneficial to improve the problem that the edge of the port of the second fluid passage 21 blocks the fluid, and is beneficial to improve the problem of air trapping.

[0056] In some embodiments, referring to Figure 3 and Figure 4 The inner wall of the end of the second fluid passage 21 communicating with the mounting groove 112 is provided with a chamfer 211. By providing the chamfer 211, it is beneficial to flow the fluid from the first fluid passage 111 into the second fluid passage 21, and reduce the fluid resistance. The angle of the chamfer 211 can be 10 degrees, 20 degrees, 30 degrees, etc., and can also be equal to the maximum rotation angle of the ball head 2 relative to the axis of the tube body 1. When the ball head 2 rotates to the maximum angle relative to the axis of the tube body 1, the surface of the chamfer is parallel to the axis of the tube body 1.

[0057] In some embodiments, referring to Figure 3The pipe body 1 is provided with a flow-limiting structure 13 in the first fluid channel 111. The flow-limiting structure 13 can be a throat portion with a reduced inner diameter of the first fluid channel 111; or a component embedded in the first fluid channel 111, and a gap between the component and the inner wall of the first fluid channel 111, or a channel through which fluid flows. The flow-limiting structure 13 can reduce the flow of fluid into the first fluid channel 111, reduce the fluid pressure, and improve the problem of easy splashing of fluid after being sprayed from the ball head 2.

[0058] For the pipe body 1 mounted on the external device, in some embodiments, referring to Figures 2 to 4 The pipe body 1 includes a pipe portion 11 and a flange portion 14 provided on the outer periphery of the pipe portion 11; the spray head device 100 further includes a fastening ring 4 threadedly connected with the pipe portion 11 to clamp the external device with the flange portion 14. For example, the external device has a through hole, the pipe portion 11 is arranged in the through hole, and the flange portion 14 and the fastening ring 4 are located on the two sides of the through hole, respectively. By tightening the fastening ring 4, the pipe body 1 can be fixed on the external device; by loosening the fastening ring 4, the pipe body 1 can be released, and the angle of the pipe body 1 relative to the external device can be adjusted; when the fastening ring 4 is detached from the pipe body 1, the pipe body 1 can be pulled away from the external device along the end where the flange portion 14 is located. Optionally, the fastening ring 4 is a nut. Optionally, the connecting wall 12 is connected to the pipe portion 11 through the flange portion 14.

[0059] In some embodiments, referring to Figures 1 to 3 The spray head device 100 further includes an elastic pad 5 supported between the pipe portion 11 and the flange portion 14 and the external device, or supported between the pipe portion 11 and the fastening ring 4 and the external device. The number of the elastic pad 5 is one or more. When the number of the elastic pad 5 is one, the elastic pad 5 is sleeved on the pipe portion 11 and located between the flange portion 14 and the external device or between the fastening ring 4 and the external device; when the number of the elastic pad 5 is two, both of the two elastic pads 5 are sleeved on the pipe portion 11, and one of the two elastic pads 5 is located between the flange portion 14 and the external device, and the other is located between the fastening ring 4 and the external device. The elastic pad 5 can be made of rubber, silicone or other elastic materials. The elastic pad 5 is beneficial to increase the firmness and sealing performance of the spray head device 100 mounted on the external device. The axial cross section of the elastic pad 5 is in the shape of “L”, so that the elastic pad 5 can be supported between the pipe portion 11 and the flange portion 14 and the external device, or between the pipe portion 11 and the fastening ring 4 and the external device.

[0060] In some embodiments, referring to Figures 1 to 3The spray head device 100 further comprises a gasket 6 supported between the fastening ring 4 and the external device. The gasket 6 can be a metal ring. The gasket 6 is used to bear the friction of the fastening ring 4 when being loosened and tightened, and to improve the problem of the fastening ring 4 wearing the external device. When the elastic pad 5 is arranged between the fastening ring 4 and the external device, the gasket 6 is arranged between the elastic pad 5 and the fastening ring 4, which is conducive to reducing the friction of the elastic pad 5 on the fastening ring 4, improving the problem that the fastening ring 4 is difficult to turn, and can uniformly transmit the pressure of the fastening ring 4 to the elastic pad 5, so that the elastic pad 5 is uniformly stressed, and the problem that the elastic pad 5 is easily damaged due to uneven stress is improved.

[0061] In some embodiments, referring to Figures 1 to 3 The spray head device 100 further comprises a sealing ring 7 sleeved on the pipe portion 11, and the sealing ring 7 is used to be clamped between the pipe portion 11 and the external pipeline. The sealing ring 7 can be made of rubber, silicone or other materials with sealing performance, which is conducive to increasing the sealing performance of the first fluid passage 111 in communication with the external pipeline.

[0062] In a second aspect, the embodiments of the present application provide a smart toilet (not shown), which comprises the spray head device 100. The smart toilet has the structural features and beneficial effects of the spray head device 100, which will not be described here.

[0063] The spray head device 100 and the smart toilet of the embodiments of the present application are characterized in that the ball head 2 is recessed in the gland 3, i.e. the ball head 2 is located inside the pipe body 1 and the gland 3, which is conducive to reducing the risk of accidental change of the angle of the ball head 2 relative to the pipe body 1. The abutting portion 32 abuts against the ball head 2 in the cavity of the connecting portion 31, so that the ball head 2 moves towards the pipe body 1 relative to the connecting portion 31, which is conducive to shortening the width of the connecting portion 31 in the axial direction of the pipe body 1. The connecting portion 31 and the abutting portion 32 are connected by the ring portion 33, which is conducive to shortening the width of the connecting portion 31 and the abutting portion 32 in the axial direction of the pipe body 1. The side of the ball head 2 away from the pipe body 1 is provided with a limiting rib 22 for preventing the ball head 2 from rotating when abutting against the gland 3, which is conducive to improving the problems that the second fluid passage 21 is blocked by the abutting portion 32 and the fluid sprayed from the second fluid passage 21 touches the abutting portion 32 due to excessive rotation of the ball head 2.

[0064] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; under the idea of the present application, the technical features in the above examples or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
