Description

Technical Field

[0001] The invention relates to the field of sanitary 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 inside the water outlet 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 external drainage flow 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. For example, patent documents such as CN211636050U, CN203389782U, CN114991264A and CN217352737U all disclose a scheme in which an air input channel is arranged in the gap between two flow panels, and air is introduced from the external atmosphere through the fitting part or the opening of the parts 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 a negative pressure, thereby attracting 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 introduce a bubble water flow formed by a mixture of a high-speed jet and air into a cavity further downstream. The bubble water flow can be rectified in the cavity and then discharged to the outside through a 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 larger pressure, there is a certain probability that the water flow will be in the following direction: 1. The water flow will overflow 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 panels and overflow from the part matching point or the part opening. The above water flow overflow will eventually manifest as leakage of the water outlet device. Summary of the invention

[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 easy to occur in the existing water outlet devices.

[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 passing panel and a second water passing panel which are sequentially arranged along the axial direction of the water outlet device;

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

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

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

[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 of water due to collision with the water body, a blocking member is arranged 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 block the backflow of water from entering the second water through hole, and make the backflow of 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, which can reduce the backflow of water flow to a certain extent, solves the problem in the prior art that the backflow of water is easy to overflow from the fitting part and the suction gap to cause water leakage of the water outlet device, and improves the quality of the water outlet device.

[0033] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0034] Please refer to Figure 2-Figure 13 The water outlet device comprises a first water-passing panel 1, a second water-passing panel 2 and a shell 3 which are sequentially arranged along the axial direction of the water outlet device; the first water-passing panel 1 is provided with at least one first water-passing hole 11; the second water-passing panel 2 is provided with at least one second water-passing hole 21 which is connected with the first water-passing hole 11; the shell 3 has a water inlet 31 and a drain 32; the drain 32 is provided with a rectifying member 4, and the rectifying member 4 is provided with at least one drain 41 which is connected with the water inlet 31; the second water-passing panel 2 is arranged in the water inlet 31, and a blocking member 5 is arranged around the outlet of the second water-passing hole 21, and a first distance h is provided between the end surface of the blocking member 5 which is away from the first water-passing panel 1 and the plate surface of the second water-passing panel 2 which is away from the first water-passing panel 1 in the axial direction. The water flows in from the inlet of the first water-passing hole 11 and flows out from the outlet of the first water-passing hole 11, then flows in from the inlet of the second water-passing hole 21 and flows out from the outlet of the second water-passing hole 21, and finally is discharged to the external space from the drain 41.

[0035] It can be understood that the present invention sets 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, which causes the water flowing out of the second water hole 21 to collide with the water body and produce a direct backflow, or produce a water flow in the opposite direction along the inner wall of the shell 3, the water flow is blocked in 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. To a certain extent, the backflow of water can be reduced, and the problem that the backflow of water in the prior art 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.

[0036] 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 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.

[0037] In some embodiments, in the circumferential direction of the water outlet device, there is a second spacing between adjacent blocking members 5. The second spacing is set to accommodate more backflow water flow to further reduce the probability of overflow.

[0038] 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 accommodating 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 an inclined surface. The inclined surface formed by the reduced 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.

[0039] In some embodiments, all the second water holes 21 form at least two groups of water hole groups; in the radial direction of the water outlet device, the blocking member 5 between adjacent water hole groups has a third spacing L. Specifically, all the water hole groups are arranged around the axis of the second water flow panel 2, but the radius of the virtual circle formed by each group of water hole groups is different. The third spacing L is set to further expand the space for accommodating water flow.

[0040] 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 second water-passing panel 2 away from the first water-passing 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 second water-passing panel 2 away from the first water-passing panel 1. When the proportion is smaller, the space left for the side of the second water-passing panel 2 away from the first water-passing panel 1 is larger, and the space for accommodating the water flow is also larger, providing sufficient buffer space for the backflow of water. In order to further expand the space for accommodating the backflow of water and reduce the probability of backflow, a groove is provided on the side of the second water-passing panel 2 away from the first water-passing panel 1, and the groove is located between adjacent blocking members 5.

[0041] 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 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.

[0042] In some embodiments, the connection relationship between the housing 3 and the rectifying member 4 has the following two solutions: one possible solution is that the housing 3 and the rectifying member 4 are integrally formed, and the second possible solution is that the rectifying member 4 is rotatably and detachably installed at the drain port 32 of the housing 3. Regardless of which of the above solutions is adopted, the sealing between the housing 3 and the rectifying member 4 should be ensured to reduce the risk of water leakage of the water outlet device and ensure that there is sufficient water outlet pressure inside the water outlet device.

[0043] In some embodiments, the inlet of the second water hole 21 and / or the outlet of the second water hole 21 are in the shape of a circle, a regular polygon, a sector, a strip or an annular ring, and in order 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 shape of the first water hole 11 should be consistent with the inlet shape of the second water hole 21. One possible implementation is that the inlet of the second water hole 21 and the outlet of the second water hole 21 are both circular, another possible implementation is that the inlet of the second water hole 21 is circular, and the outlet of the second water hole 21 are both regular polygons, sectors, strips or annular rings, and the third possible implementation is that the inlet of the second water hole 21 is a regular polygon, a sector, a strip or annular ring, and the outlet of the second water hole 21 is circular. In addition, it is also possible that the inlet of the second water hole 21 and the inlet of the second water hole 21 are different in shape, and the inlet of the second water hole 21 and the inlet of the second water hole 21 are regular polygons, sectors, strips or annular rings respectively. When the cross-sections of the inlet and outlet of the second water hole 21 are the same as the cross-section of the outlet of the first water hole 11, it can be ensured that the water flow from the first water hole 11 attracts air to approach it and then completely enters the second water hole 21 to mix with the air. Therefore, as a preferred embodiment, the cross-sections of the outlet of the first water hole 11 and the inlet and outlet of the second water hole 21 are the same. When the cross-section of the outlet of the first water hole 11 is a square or other regular polygon, the contact area between the outlet of the first water hole 11 and the air suction gap 5 can be expanded, thereby increasing the gas content in the water flow. When the cross-section of the outlet of the first water hole 11 is a circle, the air suction volume of the water outlet can be made more uniform.

In addition, the blocking members 5 connected to each water hole located in the inner circle are independent of each other. At this time, in the radial direction of the water outlet device, the independent blocking members 5 have a second spacing, and the blocking members 5 connected to each water hole located in the outer circle are connected to each other to form a whole.

[0049] 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.

[0050] Please refer to Fig. 9 , Embodiment 2 of the present invention is:

[0059] The arrangement of the rectifying member 4 in this embodiment is to change the water outlet direction and the shape of the water spray by flipping the rectifying member 4 at the water outlet end of the water outlet device. In addition, since the rectifying member 4 in this embodiment is flippable, it can clean the impurities or scales blocked in the drainage hole 41 by flipping the water outlet surface after long-term use, thereby reducing the difficulty of cleaning the water outlet device.
