DETAILED DESCRIPTION
[0027] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.
[0028] Referring toFigures 1-6 A microbubble device includes a housing 100, a water inlet 200, a ring 300, and a filter 400. The water inlet 200, the ring 300, and the filter 400 are installed inside the housing 100. The housing 100 is sleeve-shaped with threads on its outer wall. The water inlet 200 is disc-shaped and embedded inside the housing 100. The outer periphery of the water inlet 200 is clearance-fitted with the housing 100. The housing 100 has a vent hole 110 connecting the internal and external environments of the housing 100. The top wall of the water inlet 200 has a water inlet hole 210, and the lower end face of the top wall has a ring 220 forming a mixing chamber 230. The water inlet hole 210 is located above the mixing chamber 230 and communicates with the mixing chamber 230. The ring 220 has an air intake hole 221. 1. The internal environment of the mixing chamber 230 and the housing 100 is connected. The ring body 300 is located below the water inlet 200. A microbubble generating chamber 310 is formed inside the ring body 300. A water passage hole 320 is opened on the top wall of the ring body 300, which connects the mixing chamber 230 and the microbubble generating chamber 310. The filter screen 400 is located between the microbubble generating chamber 310 and the water outlet at the bottom of the housing 100. The top wall of the ring body 300 abuts against the ring body 220. A stop block 330 is provided on the top wall of the ring body 300. The water inlet 200 is fixed relative to the housing 100. The ring body 300 is rotatable relative to the housing 100. When the ring body 300 rotates to the first position, the stop block 330 is offset from the air intake hole 221. When the ring body 300 rotates to the second position, the stop block 330 blocks the air intake hole 221.
[0029] Working principle: When the ring body 300 is in the first position, when water flows into the mixing chamber 230 through the inlet, due to negative pressure, the air intake 221 begins to draw in air, and the airflow and water flow begin to mix. The mixed water-air mixture enters the microbubble generating chamber 310 through the water hole 320. In the microbubble generating chamber 310, most of the water-air mixture passes through the filter screen 400 at different angles, thus forming microbubble water. A small portion of the water-air mixture impacts the filter screen 400 and bounces back. The bounced water-air mixture, under the action of the chamber wall of the microbubble generating chamber 310, returns to the filter screen 400, is cut by the filter screen 400, and forms microbubble water again. Finally, the microbubble water flows out from the outlet. Rotate the ring body 300 to the second position (e.g., Figure 6 As shown), the baffle 330 blocks the air intake hole 221. At this time, the water type changes from microbubble water to ordinary pure water. Due to the obstruction of the filter screen 400, the water passage area of the filter screen 400 is small, and the internal structure is easily filled with water, completely removing the internal air. At this time, the pure water flows out of the outlet at a slower speed and in a uniform direction, thereby achieving a laminar flow effect and having a splash-proof function.
[0030] In some embodiments of the utility model, the bottom of shell 100 is equipped with a groove 120 along the circumference, the groove 120 is equipped with a circular arc shaped limiting hole 121 at the groove bottom, the lower edge of ring sleeve body 300 is embedded in groove 120, ring sleeve body 300 can rotate along groove 120, the lower edge of ring sleeve body 300 is equipped with a switching rod 340, the switching rod 340 is inserted into limiting hole 121 and can slide along limiting hole 121. Limiting hole 121 is a through hole, for limiting the rotation angle of ring sleeve body 300, the switching rod 340 is inserted into limiting hole 121, the user can rotate the switching rod 340 from the bottom of shell 100, so that ring sleeve body 300 rotates to the second position, the two ends of limiting hole 121 are respectively limited in the first position and the second position. It can be understood that the number of limiting hole 121 is not limited to one, and two or more limiting holes 121 can be arranged along the circumference of shell 100.
[0031] In some embodiments of the utility model, a water blocking cavity 350 is further formed in ring sleeve body 300, the water blocking cavity 350 is located between water passing hole 320 and micro-bubble generating cavity 310, the diameter of water blocking cavity 350 is smaller than that of micro-bubble generating cavity 310 and larger than that of water passing hole 320. Water passing hole 320, water blocking cavity 350 and micro-bubble generating cavity 310 are coaxially arranged. As shown in Figure 5 The water and gas mixture rebounding after hitting filter screen 400 will hit the upper wall of micro-bubble generating cavity 310 and then rebound to filter screen 400, because the distance between the upper wall of micro-bubble generating cavity 310 and filter screen 400 is not large, the speed of the water and gas mixture rebounding to filter screen 400 is still very fast, and micro-bubble water can still be formed. Part of the water and gas mixture rebounding from filter screen 400 will reach water blocking cavity 350, and the upper wall of water blocking cavity 350 will block the water from flowing upward, preventing the phenomenon of backflow of water under low water pressure. If water blocking cavity 350 is not arranged, more water will concentrate and flow upward from water passing hole 320 under the same water volume, and the diameter of water blocking cavity 350 is made smaller than that of micro-bubble generating cavity 310 and larger than that of water passing hole 320, so that ring sleeve body 300 has a stepped structure, which ensures that the speed of the rebounding water of micro-bubble generating cavity 310 can form micro-bubbles, and effectively prevents the backflow of water under low pressure.
[0032] In some embodiments of the utility model, a plurality of air suction holes 221 are arranged and spaced apart along the circumference of circular ring body 220, and correspondingly, the number of stop blocks 330 is the same as that of air suction holes 221, and the stop blocks 330 are distributed along the top wall of ring sleeve body 300. The plurality of air suction holes 221 ensure sufficient air suction, avoiding the problem of too high water flow intensity and too low micro-bubble content.
[0033] In some embodiments of the utility model, the diameter of mixed cavity 230 is same with the diameter of water passing hole 320, mixed cavity 230 is coaxially arranged with water passing hole 320.If the diameter of water passing hole 320 is less than the diameter of mixed cavity 230, the water flow from water inlet hole 210 can be blocked by the side wall of water passing hole 320, and the water flow from air suction hole 221 can be blocked.If the diameter of water passing hole 320 is greater than the diameter of mixed cavity 230, the water blocking effect of water blocking cavity 350 can be reduced.
[0034] In some embodiments of the utility model, water inlet hole 210 is provided with multiple, multiple water inlet holes 210 are all located above mixed cavity 230, and a distance is left between each water inlet hole 210 and the side wall of mixed cavity 230.If water inlet hole 210 is close to the side wall of mixed cavity 230, the incoming water can flow along the side wall of mixed cavity 230 to air suction hole 221 and flow out from air suction hole 221, and a certain distance is left between water inlet hole 210 and the side wall of mixed cavity 230 to ensure that the water only flows downward.
[0035] In some embodiments of the utility model, as shown in Figure 4 The shortest distance of water inlet hole 210 to the side wall of mixed cavity 230 is d1, the aperture of water passing hole 320 is d2, and at least one water inlet hole 210 satisfies 0 < d1 < 0.1d2.Further, multiple water inlet holes 210 are distributed along the circumference of mixed cavity 230, and each water inlet hole 210 satisfies 0 < d1 < 0.1d2.Under low water pressure, the water impact is weak, and most of the water can not pass through filter screen 400, and the returned water is relatively more, at this time, water blocking cavity 350 can also have a probability of failure, and if the shortest distance d1 of water inlet hole 210 to the side wall of mixed cavity 230 is reduced, the water flowing down can collide with the returned water, further preventing the water from flowing back.
[0036] In some embodiments of the utility model, the top edge of water inlet part 200 is embedded with sealing ring 500 along the circumference.Some existing bubble devices need to be assembled by buckles, the utility model sequentially installs filter screen 400, ring sleeve body 300, water inlet part 200 and sealing ring 500 into shell 100 during assembly, and finally shell 100 is installed into water outlet device, this structure does not need buckles, is simple to assemble, is easy to disassemble and is convenient for cleaning filter screen 400.It should be noted that the top wall of ring sleeve body 300 and water inlet part 200 are in normal abutment, do not need to be pressed tightly, and the contact between the two needs to ensure that ring sleeve body 300 can rotate smoothly.
[0037] In some embodiments of the utility model, multiple air holes 110 are provided, and multiple air holes 110 are arranged on the side wall of shell 100 and are distributed along the circumference of shell 100.The multiple air holes 110 ensure that enough air is sucked in.
[0038] A water outlet device comprising the above micro-bubble device.
[0039] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
