Description

Water outlet device Technical Field

[0001] The present invention relates to the field of sanitary ware water outlet structures, in particular to a water outlet device. Background Art

[0002] In some bathroom products, water is usually mixed with air sucked in from outside the water outlet device to form a water flow containing air, which is then discharged to the outside. The water flow containing air has a better flushing effect, can reduce the splashing of the water flow discharged to the outside and save water.

[0003] In order to allow air outside the water outlet device to enter the water outlet device, it is usually necessary to reserve an air input channel in the water outlet device. Patent documents such as CN211636050U, CN203389782U, CN114991264A and CN217352737U all disclose a scheme in which an air input channel is set in the gap between two flow panels and air is introduced from the external atmosphere through the part matching point or part opening of the water outlet device. In these schemes, the water flow hole of the first water flow panel located upstream has a smaller aperture to generate a high-speed jet to create negative pressure and thus attract external air into the gap between the two water flow panels. The water flow hole of the second water flow panel located downstream has a larger aperture to be used to introduce the bubble water flow mixed with the high-speed jet and air into the cavity further downstream. The bubble water flow can be rectified in the cavity and discharged to the outside through the discharge port located at the bottom of the cavity.

[0004] In the above scheme, if the total discharge area of ​​the discharge port is designed to be smaller in order to form water splashes with different functions, and the water in the cavity is allowed to generate a higher pressure, there is a certain probability that the following situations will occur in the direction of the water flow: 1. The water flow will overflow outward along the second water flow panel and other pores on the cavity shell except the discharge port; 2. The water flow will flow back through the water flow hole along the side wall around the outflow side of the water flow hole on the second water flow panel to the gap between the two flow flow panels and overflow outward from the part matching point or part opening. The above water flow overflow will eventually manifest as leakage of the water outlet device. Technical issues

[0005] The technical problem to be solved by the present invention is to provide a water outlet device to overcome the water leakage problem that is easily occurred in the existing water outlet devices. Technical Solutions

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The water outlet device comprises a first water flow panel and a second water flow panel sequentially arranged along the axial direction of the water outlet device;

[0008] The first water flow panel is provided with at least one first water flow hole;

[0009] The second water flow panel is provided with at least one second water flow hole communicating with the first water flow hole;

[0010] A blocking member is arranged around the outlet of the second water hole. In the axial direction of the water outlet device, there is a first distance between the end surface of the blocking member away from the first water flow panel and the side surface of the second water flow panel away from the first water flow panel. Beneficial effects

[0011] The beneficial effect of the present invention is that when the water flowing out of the second water through hole generates direct backflow or reverse flow due to collision with the water body, a blocking member is set at the outlet of the second water through hole, and the water flow is blocked in height by relying on the first spacing. The blocking member can prevent the backflow water from entering the second water through hole, and make the backflow water flow into the space enclosed by the blocking member and the drainage side of the second water through panel and then fall back into the inner cavity of the water outlet device, and finally be discharged from the water outlet device. To a certain extent, the backflow water flow can be reduced, and the problem in the prior art that the backflow water flow is easy to overflow from the parts matching and the suction gap to cause water leakage of the water outlet device is solved, thereby improving the quality of the water outlet device.

[0034] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0035] Please refer to Figures 2 to 13. The water outlet device includes a first water flow panel 1, a second water flow panel 2 and a shell 3 arranged in sequence along the axial direction of the water outlet device; the first water flow panel 1 is provided with at least one first water flow hole 11; the second water flow panel 2 is provided with at least one second water flow hole 21 connected to the first water flow hole 11; the shell 3 has a water inlet 31 and a drain outlet 32; the drain outlet 32 ​​is provided with a rectifying member 4, and the rectifying member 4 is provided with at least one drain hole 41 connected to the water inlet 31; the second water flow panel 2 is arranged in the water inlet 31, and a blocking member 5 is arranged around the outlet of the second water flow hole 21. In the axial direction, there is a first distance h between the end face of the blocking member 5 on one side away from the first water flow panel 1 and the plate surface of the second water flow panel 2 on the side away from the first water flow panel 1. The water flows in from the inlet of the first water hole 11 and out from the outlet of the first water hole 11 , then flows in from the inlet of the second water hole 21 and out from the outlet of the second water hole 21 , and finally is discharged to the outside space from the drainage hole 41 .

[0036] It can be understood that the present invention provides a blocking member 5 at the outlet of the second water hole 21. When the shell 3 is full of water due to poor drainage of the cavity drain port 32, and the water flowing out of the second water hole 21 collides with the water body to produce a direct backflow, or produces a water flow in the opposite direction along the inner wall of the shell 3, the water flow is blocked at a height by relying on the first spacing h. The blocking member 5 can prevent the backflow of water from entering the second water hole 21, and make the backflow of water flow into the space enclosed by the blocking member 5 and the drainage side of the second water panel 2 and then fall back into the shell 3, and finally be discharged from the water outlet device. This can reduce the backflow of water to a certain extent, solve the problem in the prior art that the backflow of water easily overflows from the parts fitting and the suction gap to cause water leakage in the water outlet device, and improve the quality of the water outlet device.

[0037] In some embodiments, the first spacing h is greater than 0.2 mm. When the outlet inner diameter of the second water hole 21 is larger, the water flow rate is greater, and the height requirement for the first spacing h is greater. The first spacing h should be greater than 0.2 mm to ensure the water flow blocking effect.

[0038] In some embodiments, a second spacing is provided between adjacent blocking members 5 in the circumferential direction of the water outlet device. The second spacing is provided to accommodate more backflow water to further reduce the probability of overflow.

[0039] In some embodiments, in order to perfectly match the water outlet device with the water outlet equipment, the size of the overall structure is limited and the size of the water outlet device needs to meet industry standards. Therefore, the wall thickness of the blocking member 5 is less than 3 mm, which can provide a sufficiently large accommodation space for the water flow within a limited space, or the wall thickness of the blocking member 5 gradually decreases along the water outlet direction. When the wall thickness of the blocking member 5 is smaller, the area left for the side of the second water flow panel 2 away from the first water flow panel 1 is larger, and the space that can accommodate the water flow is larger. Specifically, the outer diameter of the blocking member gradually decreases along the water outlet direction, so that the outer wall of the blocking member forms a slope. The slope formed by the reduction in the wall thickness of the blocking member is conducive to allowing the water flow to flow back to the bottom of the panel to ensure the water flow blocking effect.

[0040] In some embodiments, all second water holes 21 form at least two groups of water hole groups. In the radial direction of the water outlet device, the blocking members 5 between adjacent water hole groups have a third spacing L. Specifically, all water hole groups are arranged around the axis of the second water outlet panel 2, but the radius of the virtual circle formed by each water hole group is different. The third spacing L is provided to further expand the space for accommodating water flow.

[0041] In some embodiments, in the axial direction of the water outlet device, the sum of the projected areas of all the blocking members 5 is 5% to 40% of the projected area of ​​the side of the second water flow panel 2 away from the first water flow panel 1. Optionally, the sum of the projected areas of all the blocking members 5 is 5%, 10%, 15%, 20%, 25%, 30%, 35%, or 40% of the surface area of ​​the side of the second water flow panel 2 away from the first water flow panel 1. The smaller the proportion, the larger the space left for the side of the second water flow panel 2 away from the first water flow panel 1, and the larger the space to accommodate water flow, providing sufficient buffer space for backflow water flow. In order to further expand the space to accommodate backflow water flow and reduce the probability of backflow, a groove is provided on the side of the second water flow panel 2 away from the first water flow panel 1, and the groove is located between adjacent blocking members 5.

[0042] In some embodiments, in the axial direction of the water outlet device, the outlet of the first water hole 11 is opposite to the inlet of the second water hole 21, and the projected area of ​​the outlet of the first water hole 11 is smaller than the projected area of ​​the inlet of the second water hole 21; in the axial direction of the water outlet device, the sum of the projected areas of the outlets of all the second water holes 21 is 0.6 to 2 times the sum of the projected areas of the outlets of all the drainage holes 41. Optionally, the ratio is 0.63 times, 0.7 times, 0.85 times, 0.9 times, 1 times, 1.1 times, 1.2 times, 1.3 times, 1.4 times, 1.5 times, 1.6 times, 1.7 times, 1.8 times, 1.9 times or 2 times. When the ratio of the sum of the projected areas of the outlets of the second water holes 21 to the sum of the projected areas of the outlets of all the drainage holes 41 is within this numerical range, the water outlet device can have an optimal water pressure range. When the ratio is greater than twice, the excessive water pressure will cause the sealing structure of the water outlet device to fail and thus cause the entire product to leak. When the ratio is less than one, the water pressure inside the water outlet device is insufficient and the water splash cannot be formed, affecting the water outlet pressure and the water splash forming effect.

[0043] In some embodiments, the connection between the housing 3 and the rectifying member 4 has the following two options: one possible option is that the housing 3 and the rectifying member 4 are integrally formed, and the second possible option is that the rectifying member 4 is rotatably and detachably mounted to the drain port 32 of the housing 3. Regardless of which option is adopted, the sealing between the housing 3 and the rectifying member 4 must be ensured to reduce the risk of water leakage from the water outlet device and ensure sufficient water pressure inside the water outlet device.

[0044] In some embodiments, the inlet and / or outlet of the second water hole 21 are shaped like a circle, a regular polygon, a sector, a strip, or an annular ring. To ensure that the water flow from the first water hole 11 can completely enter the second water hole 21 after inhaling air, the outlet of the first water hole 11 should be consistent with the inlet of the second water hole 21. In one possible embodiment, the inlet and outlet of the second water hole 21 are both circular. In another possible embodiment, the inlet of the second water hole 21 is circular, while the outlet of the second water hole 21 is both a regular polygon, a sector, a strip, or an annular ring. In a third possible embodiment, the inlet of the second water hole 21 is a regular polygon, a sector, a strip, or an annular ring, while the outlet of the second water hole 21 is circular. Furthermore, there are also possibilities where the inlet and inlet of the second water hole 21 have different shapes, with the inlet of the second water hole 21 and the inlet of the second water hole 21 each being a regular polygon, a sector, a strip, or an annular ring. When the cross-sections of the inlet and outlet of the second water passage 21 are identical to the cross-section of the outlet of the first water passage 11, the water flow from the first water passage 11 can be ensured to draw air toward it, and then the water flow and the air can be completely mixed in the second water passage 21. Therefore, preferably, the cross-sections of the outlet of the first water passage 11 and the inlet and outlet of the second water passage 21 are identical. When the cross-section of the outlet of the first water passage 11 is square or another regular polygonal shape, the contact area between the outlet of the first water passage 11 and the air intake gap 5 can be increased, thereby increasing the gas content in the water flow. When the cross-section of the outlet of the first water passage 11 is circular, the air intake of the water can be more uniform.

[0045] 2 to 8 , the first embodiment of the present invention is as follows:

[0046] A water outlet device includes a first water flow panel 1, a second water flow panel 2, and a shell 3 located on the side of the second water flow panel 2 away from the first water flow panel 1, which are arranged in sequence along the axial direction of the water outlet device; the first water flow panel 1 is provided with a plurality of first water flow holes 11, and the plurality of first water flow holes 11 are arranged around the axis of the first water flow panel 1; the second water flow panel 2 is provided with a plurality of second water flow holes 21 connected to the first water flow holes 11, and the second water flow holes 21 are arranged around the axis of the second water flow panel 2; the shell 3 has a water inlet 31 and a drain outlet 32; the drain outlet 32 ​​is provided with a rectifying member 4, and the rectifying member 4 is provided with a plurality of drain holes 41 connected to the water inlet 31; a blocking member 5 is arranged around the outlet of the second water flow hole 21, and a first spacing h is formed between the side of the blocking member 5 away from the first water flow panel 1 and the side of the second water flow panel 2 away from the first water flow panel 1, and the first spacing h is greater than 0.2 mm, and the wall thickness of the blocking member 5 is less than 3 mm. In addition, a groove is formed on a side of the second water overflow panel 2 away from the first water overflow panel 1 , and the groove is located between adjacent blocking members 5 .

[0047] In this embodiment, all second water holes 21 constitute two groups of water hole groups; in the radial direction of the water outlet device, the blocking members 5 between adjacent water hole groups have a third spacing L. Specifically, both groups of water hole groups are arranged around the axis of the second water outlet panel 2, and one of the water hole groups is arranged around the outside of the other water hole group. The water hole group located closer to the axis of the second water outlet panel 2 is defined as the inner circle, and the water hole group located farther from the axis of the second water outlet panel 2 is defined as the inner circle. The spacing between the water holes on the inner circle is greater than the spacing between the water holes on the outer circle. In addition, the blocking members 5 connected to each water hole in the inner circle are independent of each other. In this case, in the radial direction of the water outlet device, the independent blocking members 5 have the second spacing between them, while the blocking members 5 connected to each water hole in the outer circle are connected to each other to form a whole.

[0048] In this embodiment, in the axial direction of the water outlet device, the sum of the projected areas of all the blocking members 5 is equal to the surface area of ​​the side of the second water flow panel 2 away from the first water flow panel 1. In addition, in the axial direction of the water outlet device, the outlet of the first water flow hole 11 is directly opposite the inlet of the second water flow hole 21, and the projected area of ​​the outlet of the first water flow hole 11 is smaller than the projected area of ​​the inlet of the second water flow hole 21. In the axial direction of the water outlet device, the sum of the projected areas of the outlets of all the second water flow holes 21 is 1.5 times the sum of the projected areas of the outlets of all the drainage holes 41. The inlet and outlet of the second water flow hole 21 are both circular.

[0049] In this embodiment, the shell 3 and the second water flow panel 2 are integrally formed, and the shell 3 and the flow straightening component 4 are integrally formed.

[0050] In this embodiment, the water outlet end of the housing 3 further comprises a front rectifying layer 42 and a rectifying net 43 which are sequentially stacked along the water outlet direction.

[0051] Please refer to FIG9 , the second embodiment of the present invention is:

[0052] The difference between this embodiment and the first embodiment is that a second structure of the second water-passing panel 2 is provided.

[0053] In this embodiment, the blocking members 5 located on the outer ring and the blocking members 5 located on the inner ring are independent of each other. At this time, in the radial direction of the water outlet device, there is a second distance between every two adjacent blocking members 5.

[0054] Please refer to FIG10 , the third embodiment of the present invention is:

[0055] The difference between this embodiment and the first embodiment is that a third structure of the second water-passing panel 2 is provided.

[0056] In this embodiment, the water hole group located on the outer ring has two coaxially arranged blocking members 5, and the water holes located on the outer ring are all located in the channel formed by the two blocking members 5, while the blocking members 5 set on the water holes located on the inner ring are still independent of each other. At this time, in the circumferential direction of the water outlet device, there is a second spacing between every two independent blocking members 5 located on the inner ring and a fourth spacing D between the two blocking members 5 located on the outer ring, and the size of the fourth spacing D is greater than or equal to the outer diameter of the second water hole 21.

[0057] 11 and 12 , the fourth embodiment of the present invention is as follows:

[0058] The difference between this embodiment and the first, second and third embodiments is that the connection method between the rectifying member 4 and the housing 3 is different.

[0059] In this embodiment, the rectifying member 4 and the water outlet end of the shell 3 can be connected relatively flippably, and a seal is provided between the rectifying member 4 and the inner wall of the water outlet end of the shell 3. The rectifying member 4 can change the water outlet surface in the axial direction of the shell 3 and form an angle between the axis of the rectifying member 4 and the axis of the shell 3.

[0060] The arrangement of the flow regulating member 4 in this embodiment is to change the direction of water discharge and the shape of the water spray by flipping the flow regulating member 4 at the outlet end of the water outlet device. Furthermore, since the flow regulating member 4 in this embodiment is flippable, it can be used to clean impurities or scale clogging the drain hole 41 after long-term use by flipping the water outlet surface, thereby reducing the difficulty of cleaning the water outlet device.

[0061] Referring to FIG. 2 and FIG. 13 , the fifth embodiment of the present invention is as follows:

[0062] The difference between this embodiment and embodiments 1 to 4 is that a sleeve 6 is provided outside the water outlet device.

[0063] The circumferential side wall of the sleeve 6 is provided with an air vent 61 and a through groove 62 extending axially along the sleeve 6. The through groove 62 is connected to the air vent 61 and extends from the through groove 62 as the starting point toward the water outlet end of the sleeve 6 to the end face of the water outlet end of the sleeve 6, so that air can enter the through groove 62 and the air vent 61 in sequence from the water outlet end of the sleeve 6 and then enter the suction gap 8.

[0064] In this embodiment, the inner wall of the water inlet end of the sleeve 6 is also provided with a mounting groove 63, and the mounting groove 63 is located at the water inlet end of the sleeve 6 and has an opening. Correspondingly, the first water flow panel 1 and the second water flow panel 2 are circumferentially provided with mounting columns 7. The mounting columns 7 of the second water flow panel 2 and the mounting columns 7 of the first water flow panel 1 can be embedded in the mounting groove 63 in sequence through the opening to ensure that the first water flow hole 11 and the second water flow hole 21 can be directly opposite.

[0065] In this embodiment, the outer portion of the sleeve 6 is covered with a shell.

[0066] It is worth noting that the direction indicated by the arrows in Figures 1 and 6 is the direction of water flow.

[0067] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
