Description

Technical Field

[0001] The utility model relates to the field of bubblers, in particular to a swinging waterfall bubbler. Background Art

[0002] A bubbler can fully mix the flowing water and air to achieve a foaming effect. With the addition of air, the scouring force of water is greatly improved, thus effectively reducing water consumption and saving water.

[0003] Inside a traditional bubbler, several bubbling plates are uniformly distributed from top to bottom, and several uniformly distributed bubbling holes are provided on the bubbling plates. When water flows through the bubbling plates, the water flow will be broken up by the bubbling holes, so that the water flow is fully mixed with air to achieve a foaming effect. In the actual foaming process, the water flow pressure and water flow rate are also key factors determining the foaming effect. However, the traditional bubbler directly guides the water flow into the bubbler housing, and the water flow pressure and water flow rate entirely depend on the user to control the valve core through the handle. Therefore, there will be a large difference in the foaming effect of the bubbler each time, and it is impossible to effectively ensure the foaming effect and the water-saving effect.

[0004] At the same time, the water outlet nozzle of the traditional bubbler is fixed. However, in the actual use process, limited by the cleaning space, it is necessary to change the water outlet direction to complete the cleaning work. At this time, if the direction of the water outlet nozzle cannot be changed, it will lead to the difficulty of completing the cleaning work, which not only affects the cleaning efficiency but also the cleaning quality.

[0035] A water dividing grid 36 is provided at the lower end mouth of the reversing nozzle 13; a number of water separating plates 37 evenly distributed are provided on the upper surface of the water dividing grid 36, and the water separating plates 37 divide the upper space of the reversing nozzle 13 into a number of evenly distributed water separating spaces 38.

[0036] A sealing groove 39 in a runway shape is provided on the upper part of the housing 1; a sealing ring 40 matching the sealing groove 39 is provided in the sealing groove 39; a runway-shaped embedding groove 41 is provided on the outer wall of the swinging portion 14; an O-ring 42 matching the embedding groove 41 is provided in the embedding groove 41.

[0037] On the left and right sides of the lower part of the housing 1, there are symmetrically arranged notches 43; on the inner wall of the upper side of the notch 43, there is an elastic arm 44; on the outer wall of the middle part of the elastic arm 44, there is a clamping part 45; on the outer wall of the lower end of the elastic arm 44, there is a pressing part 46.

[0038] The housing 1 is flat; the lower end orifice of the reversing nozzle 13 is in the shape of an oblong hole.

[0039] The usage method of the present utility model is as follows:

[0040] When the bubbler needs to be used, the bubbler can be directly installed in the water outlet end of the sanitary ware body, for example, installed in the faucet nozzle. At this time, the sealing ring 40 provided on the upper part of the housing 1 of the bubbler can effectively ensure the sealing performance and play a role in preventing water leakage. On the left and right sides of the faucet nozzle, clamping holes matching the clamping part 45 can be set. First, press the elastic arm 44 through the pressing part 46 so that the elastic arm 44 can be embedded into the faucet nozzle along with the housing 1. Then, when the pressing part 46 is released, the elastic arm 44 will, under its own elastic action, pop the clamping part 45 into the clamping hole, thereby effectively fixing the housing in the faucet nozzle. This fixing method is convenient for the disassembly of the housing 1 and is beneficial to the maintenance and replacement of the bubbler.

[0041] After the faucet is opened, the water flow will directly impact downward on the upper surface of the flow buffer plate 6. The flow buffer plate 6 can block the downward flowing water through its upper surface and effectively buffer the pressure of the water flow. At the same time, the outer edge of the upper surface of the flow buffer plate 6 has a sunken groove 47 with a certain arc, which can further buffer the water flow pressure. With the buffer contact, the water flow will enter the groove 5 through the flow buffer holes 7 and then converge towards the adjustment groove 8. The flow limiting hole 15 at the center of the bottom of the adjustment groove 8 is divided into several holes evenly distributed in a circle by the flow limiting arm 17 and the connecting arm 18, thereby effectively limiting the water flow rate flowing downward at a moment. When actually adjusting the flow rate, a rubber ring 48 can also be set in the adjustment groove 8. The rubber ring 48 can effectively fill the internal space of the adjustment groove 8, thereby further controlling the water flow rate by controlling the size of the internal space of the adjustment groove 8.

[0042] When the water flow is restricted to a certain flow rate and flows under the flow limiting plate 4, the water flow will enter the diversion groove 10, causing the water flow that was originally converged in the center to disperse. Then, it is diverted through the diversion holes 11 and evenly flows upward to the upper bubbling plate 19. As the water flow passes through the upper bubbling holes 24 on the upper bubbling plate 19, the upper bubbling holes 24 will break up the water flow, enabling it to be fully mixed with air. After the water flow passes through the upper bubbling holes 24, it will enter the water receiving groove 23. The presence of the water receiving groove 23 can effectively prevent the situation where the lower surface of the upper bubbling plate 19 covers the upper orifice of the lower bubbling holes 27. The water flow entering the water receiving groove 23 will, under the push of the subsequent water flow, flow through the lower bubbling holes 27 on the lower bubbling plate 20. The presence of the lower bubbling holes 27 can further break up the water flow, enabling it to be further fully mixed with air, ensuring the foaming effect to the greatest extent. The foamed water flow will then directly flow out to the outside through the reversing nozzle for use. Since the cross-section of the swinging part 14 is elliptical and the outer wall of the swinging part 14 fits with the inner wall of the swinging groove 12, the position of the reversing nozzle 13 is fixed by the frictional force between the outer wall of the swinging part 14 and the inner wall of the swinging groove 12. When it is necessary to change the water outlet direction, just hold the lower end of the reversing nozzle 13 exposed outside and swing it. The reversing nozzle 13 will swing along the arc-shaped inner wall track of the swinging groove 12. As the reversing nozzle 13 swings, the water outlet angle of the lower nozzle of the reversing nozzle 13 will also change accordingly. When the swinging stops, the frictional force between the outer wall of the swinging part 14 and the inner wall of the swinging groove 12 will achieve the automatic fixation of the reversing nozzle 13.

[0043] As can be seen from the above, the utility model can effectively buffer the water flow through the slow flow plate 6, and at the same time use the flow limiting structure to effectively control the flow rate of the downward flowing water flow, so that the water flow flowing to the upper bubbling plate 19 and the lower bubbling plate 20 can always maintain a stable water flow pressure and water flow rate, thereby effectively ensuring the foaming effect and the water saving effect, ensuring that the water outlet is gentle, achieving a splash-proof effect, and when it is necessary to change the water outlet direction, just hold the lower end of the reversing nozzle 13 and swing it to achieve it. The entire reversing process is extremely simple, enabling the water outlet direction to adapt to different cleaning requirements, effectively ensuring the cleaning efficiency and cleaning quality.

[0044] The inner wall of the lower orifice of the limiting cover 26 is provided with an annular guiding arc surface 28, and the guiding arc surface 28 fits with the outer wall of the upper end of the swinging part 14. The guiding arc surface 28 can effectively increase the actual contact area of the swinging part 14, further increasing the external force required for the swinging of the swinging part 14, thereby ensuring the stability of the reversing nozzle 13 after the swinging stops, and at the same time effectively improving the stability of the reversing nozzle 13 during swinging.

[0045] The diameter of the diversion holes 11 gradually decreases towards the water outlet nozzle 2. When the water flow passes through the diversion holes towards the water outlet nozzle, the pressure gradually decreases, effectively buffering the water flow pressure, and at the same time being able to effectively increase the number of bubbles and improve the foaming effect.

[0046] An upper inner wall of the upper part of the housing 1 is provided with an annular upper limit step 29. An outer wall of the upper end of the flow dividing plate 9 is provided with a limit portion 30 that fits with the upper limit step 29. A lower surface of the current limiting plate 4 is provided with an annular positioning cover 31. The lower end of the positioning cover 31 presses on the upper surface of the limit portion 30. The outer wall of the upper part of the housing 1 is provided with a plurality of lower card slots 32 that communicate with its internal space. The outer wall of the positioning cover 31 is provided with a plurality of lower card blocks 33 that match the lower card slots 32. The inner wall of the groove 5 is provided with a plurality of evenly distributed upper card slots 34. The outer wall of the flow buffering plate 6 is provided with a plurality of upper card blocks 35 that match the upper card slots 34. Both the upper card block 35 and the lower card block 33 are triangular in shape with a wider upper part and a narrower lower part. This shape facilitates the insertion of the upper card block 35 into the upper card slot 34 and at the same time facilitates the insertion of the lower card block 33 into the lower card slot 32, which is beneficial to the disassembly and assembly of the current limiting plate 4 and the flow buffering plate 6.

[0047] A water distribution grid 36 is provided at the lower nozzle opening of the reversing nozzle 13. The upper surface of the water distribution grid 36 is provided with a plurality of evenly distributed water blocking plates 37. The water blocking plates 37 divide the upper space of the reversing nozzle 13 into a plurality of evenly distributed water blocking spaces. When water flows through the lower foaming holes 27 and into the upper part of the reversing nozzle 13, it will be divided into several parts by the water blocking plates 37, and then the individual parts will be separated by the water distribution grid 36, so that the water flow is dispersed again, ensuring the full mixing of water and air to the greatest extent and effectively ensuring the foaming effect.

[0048] The outer wall of the swinging portion 14 is provided with a racetrack-shaped groove 41. An O-ring 42 that matches the groove 41 is provided in the groove 41. The presence of the O-ring 42 can effectively ensure the sealing between the outer wall of the swinging portion 14 and the inner wall of the swinging groove 12, avoiding water leakage and achieving the effect of preventing water leakage.

[0049] The housing 1 is flat. The lower nozzle opening of the reversing nozzle 13 is oblong. This shape of the reversing nozzle 13 can effectively shape the water flow, making the water flow form a waterfall shape, which can not only ensure the impact force of the water flow but also effectively increase the water outlet range.

[0050] An elastic bracket 49 is provided on an outer wall of one side of the housing 1. A chuck 50 is provided at the end of the elastic bracket 49. A card hole that matches the chuck 50 is provided on the inner wall of the sanitary ware body for installing the bubbler to ensure the stability when the bubbler is installed in the sanitary ware body. The chuck 50 is located at the middle position of the housing 1, which can effectively avoid the situation that the wall thickness is insufficient due to the punching position of the card hole on the sanitary ware body being too close to the end, resulting in easy breakage.

[0051] On the front and back sides of the middle part of the outer shell 1, there are symmetrically arranged pin holes 51. On the inner wall of the pin holes 51, there are several reinforcing ribs 52 evenly distributed in a circumferential manner. Even if pins pass through the sanitary body and the pin holes simultaneously to connect the sanitary body and the bubbler, the outside air can enter the outer shell 1 through the gaps between the adjacent reinforcing ribs 52, so as to ensure that there is enough air to fully mix with the water flow and ensure the foaming effect. At the same time, several air intake holes 53 can be arranged on the outer shell 1 to provide more outside air.

[0052] On the left and right sides of the middle part of the lower surface of the flow buffer plate 6, there are symmetrically arranged reinforcing columns 54. On the left and right sides of the bottom of the groove 5, there are positioning holes 55 that match the reinforcing columns 54. The existence of the reinforcing columns 54 can effectively improve the strength of the flow buffer plate 6 and play a role in supporting the flow buffer plate 6. When the water flow directly impacts the flow buffer plate 6 from top to bottom, it can effectively improve the pressure-bearing effect of the flow buffer plate 6 and avoid the situation that the flow buffer plate 6 is deformed by the impact of the water flow.
