Description

Technical Field

[0001] The present invention relates to the field of kitchen and bathroom water equipment, and in particular to a switchable bubbler and a faucet. Background Art

[0002] Most aerators on kitchen or bathroom faucets on the market are single-function aerators, available in two types: shower water and sparkling water. Shower water aerators offer a strong flow that helps remove grease and improves flushing efficiency, but are not suitable for washing or rinsing vegetables and fruit. Sparkling water aerators offer a softer, micro-bubble-rich flow that preserves the freshness, surface texture, and taste of vegetables or fruit, but are not conducive to removing grease or improving flushing efficiency. Currently, kitchen or bathroom faucets on the market cannot simultaneously function as both shower water and sparkling water. To achieve both functions, a bulky kitchen shower head would be required, which not only affects the product's aesthetics but also increases the cost of use for consumers. In summary, single-function aerators on the market no longer meet the personalized and diverse market demands of consumers and therefore need to be continuously improved based on customer feedback.

[0033] As shown in the figure, the present invention includes a connecting joint 6, a water outlet cover 1 connected to the connecting joint 6, and a switching assembly provided between the connecting joint 6 and the water outlet cover 1. The water outlet cover 1 is rotatably connected to the connecting joint 6. The switching assembly includes a diverter 4 and a rectifier 3 fixedly connected to the water outlet cover 1. The lower surface of the connecting joint 6 is circumferentially provided with a plurality of first injection ports 9. The surface of the diverter 4 is circumferentially provided with a first functional area and a second functional area. The water outlet cover 1 rotates to switch the first injection ports 9 between the first functional area and the second functional area. The structural design of the present invention is scientific and reasonable, easy to implement, and can be adapted to a variety of different faucet products. It effectively integrates the functions of shower water and bubble water, solves the problem that the bubbler can only produce one type of water, and has great market application prospects. In addition, the bubbler uses the principles of cavitation and bubble pulsation to enhance the amount of microbubbles and oxygen content in the bubble water, optimizes the roundness and fineness of the bubble water type, and can also achieve good flushing force and water discharge effect in low water pressure areas.

[0034] According to the above embodiment, preferably, the first functional area includes a plurality of first water inlet grooves 41 arranged circumferentially, and the second functional area includes a plurality of second water inlet grooves 42 arranged circumferentially, the first water inlet grooves 41 and the second water inlet grooves 42 being arranged at intervals, the number of the first water inlet grooves 41 and the second water inlet grooves 42 being respectively equal to the number of the first jet ports 9, the first water inlet grooves 41 being connected to the outlet surface cover 1, and the second water inlet grooves 42 being connected to the rectifier 3. When the diverter 4 is installed between the connection joint 6 and the outlet surface cover 1, the upper end surface of the first water inlet groove 41 of the diverter 4 is aligned with the bottom surface of the connection joint 6, a positioning groove 12 is provided in the outlet surface cover 1, and a positioning protrusion 44 is fixed on the diverter 4, and the positioning protrusion 44 is located in the positioning groove 12, so that the outlet surface cover 1 can drive the diverter 4 to rotate, and the rectifier 3 is tightly connected between the outlet surface cover 1 and the diverter 4, and different forms of water are discharged by the rotation of the outlet surface cover 1.

[0035] According to the above embodiment, preferably, the connection between the connecting joint 6 and the water outlet cover 1 is circumferentially provided with gear mating points, and the number of the gear mating points is equal to the sum of the number of the first water inlet groove 41 and the second water inlet groove 42. In this example, the gear mating points include protrusions 5 and grooves 2, and their number is proportional to the number of the first jet port 9 and the two water inlet grooves. The mating relationship between the protrusions 5 and the grooves 2 can make the water outlet cover 1 have a sense of gear when rotating.

[0036] According to the above embodiment, preferably, a second jet port 10 is provided in the first water inlet groove 41, a first water outlet hole 8 is provided around the bottom of the water outlet cover 1, and the second jet port 10 is connected to the first water outlet hole 8. An annular partition is fixedly connected to the water outlet cover 1, which separates the first water inlet groove 41 from the rectifier 3. The first water inlet groove 41 is located outside the annular partition, and the first water outlet hole 8 is also located outside the annular partition. When the first jet port 9 is connected to the first water inlet groove 41, shower water can be discharged. The specific flow direction is as follows: water in the faucet enters the diverter 4 from the first jet port 9 of the connecting joint 6. At this time, the first jet port 9 is connected to the second jet port 10, allowing water to flow from the first water inlet groove 41 into the water outlet cover 1, and then flow out of the shower water through the first water outlet hole 8 between the annular partition and the water outlet cover 1.

[0037] According to the above embodiment, preferably, a through hole is provided in the middle of the diverter 4, and the second water inlet groove 42 is connected to the rectifier 3 through the through hole. The rectifier 3 is connected to the water outlet surface cover 1. A plurality of water holes are provided around the surface of the rectifier 3. The water hole in this example is a U-shaped hole 32. A second water outlet hole 7 is provided in the middle of the bottom surface of the water outlet surface cover 1, and the water hole is connected to the second water outlet hole 7. When the first jet port 9 is connected to the second water inlet groove 42, bubbling water can be discharged. The specific flow direction is: the water in the faucet enters the diverter 4 from the first jet port 9 of the connecting joint 6. At this time, the first jet port 9 is connected to the second water inlet groove 42. After forming bubbles in the second functional area, the water passes through the through hole, passes through the rectifier 3, and then flows out of the second water outlet hole 7 as bubbling water.

[0038] The principle by which the diverter 4 can generate bubbles is as follows: when the first jet port 9 on the connecting joint 6 is docked with the second water inlet trough 42 on the diverter 4, the fluid is ejected into the second water inlet trough 42. According to Bernoulli's principle, "in a water or air flow, if the speed is low, the pressure is high, and if the speed is high, the pressure is low", it can be argued that the fluid is accelerated through the first jet port 9, a negative pressure zone can be formed near the first jet port 9, and cavitation (named macrobubbles in this case) can be generated. The principle of cavitation formation is as follows: when the local pressure of the flowing liquid drops to the critical pressure, the gas nuclei in the liquid grow into bubbles; when the generated bubbles re-enter the high-pressure water area, they will shrink sharply or even collapse, and as the fluid pressure changes, the cavitation is transformed into bubble pulsation (named microbubbles in this case). The principle of bubble pulsation formation is as follows: during the rapid expansion of high-pressure gas underwater to form bubbles, the bubble pressure gradually decreases to the surrounding water pressure, and it will continue to expand under the action of inertia; after over-expansion, the surrounding water pressure presses the bubble back to its "original shape"; when compressed to the minimum, the air pressure inside the ball reaches the highest, and the bubble expands again; this reciprocating motion is called bubble pulsation. At this time, the large bubbles and microbubbles in the second water inlet groove 42 are in a disordered state, and the fluid is also in a turbulent state. The bubbler in this example uses the principles of cavitation and bubble pulsation to enhance the amount of microbubbles and oxygen content in the bubble water, optimize the roundness and fineness of the bubble water shape, and can also achieve good flushing force and water output effect in low water pressure areas.

[0039] The bubble field formed by the fluid flowing through the core components such as the connecting joint 6, the diverter 4, the rectifier 3, and the water outlet cover 1 in sequence can establish a negative pressure area. In this case, the gas can be sucked in from the first water outlet 8 and the fitting gap between the connecting joint 6 and the water outlet cover 1, which can further replenish the oxygen content of the bubble water.

[0040] According to the above embodiment, preferably, a plurality of rectifying columns 31 are fixedly attached to the circumference of the surface of the rectifier 3. After the fluid is diverted and agitated by the connecting joint 6 and the diverter 4, and microbubbles are formed, it enters the rectifier 3 for integration. The fluid is first buffered and decelerated by the rectifying columns 31, and then integrated and flows out through the U-shaped opening 32. At this time, the fluid changes from turbulent flow to laminar flow, and the microbubbles in the cavity change from disorder to order.

[0041] According to the above embodiment, preferably, a plurality of cylinders 43 are fixedly connected in the second water inlet groove 42 , and the cylinders 43 in the second water inlet groove 42 can accelerate the conversion of the fluid between cavitation (large bubbles) and bubble pulsation (micro bubbles).

[0042] This patent also discloses a faucet, which is characterized in that it includes the above-mentioned switchable bubbler and a faucet body 11, wherein the faucet body 11 includes a water outlet end, and the water outlet end is threadedly connected to the connecting joint 6, wherein the faucet body 11 can be an ordinary faucet or a pull-out faucet, has strong adaptability, and has good application and promotion value.

[0043] The structural design of the present invention is scientific and reasonable, easy to implement, and can be adapted to a variety of different faucet products. It effectively integrates the functions of shower water and bubble water, solves the problem that the bubbler can only produce one type of water, and has great market application prospects. In addition, the bubbler uses the principles of cavitation and bubble pulsation to enhance the amount of microbubbles and oxygen content in the bubble water, optimizes the roundness and fineness of the bubble water type, and can also achieve good flushing force and water output effect in low water pressure areas.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
