Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and particularly to a microbubble device and a water outlet device. Background Art

[0002] There are mainly two types of microbubble devices on the market. One uses an air pump to supply air. This technology realizes forced gas injection through an external booster pump. Although it can stably generate microbubbles, the cost is relatively high. The other uses the Venturi self-priming technology, which applies the Venturi principle to achieve autonomous gas inhalation. Although it has an advantage in terms of cost, due to structural limitations, it can only produce a single water type and cannot meet the demand for diversified water type switching. Summary of the Invention

[0003] The present invention aims to solve at least one of the above technical problems in the related art to some extent. For this purpose, the present invention provides a microbubble device.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] The present invention also provides a water outlet device having the above microbubble device.

[0006] The microbubble device according to the first aspect embodiment of the present invention includes a housing, a water inlet member, a ring sleeve body, and a filter screen. The water inlet member, the ring sleeve body, and the filter screen are installed in the housing. The housing is provided with a ventilation hole communicating the internal and external environments of the housing. The top wall of the water inlet member is provided with a water inlet hole, and a circular ring body is provided on the lower end surface of the top wall. A mixing chamber is formed by the circular ring body. The water inlet hole is located above the mixing chamber. The circular ring body is provided with an air suction hole, and the air suction hole communicates the mixing chamber and the internal environment of the housing. The ring sleeve body is located below the water inlet member. A microbubble generation chamber is formed inside the ring sleeve body. The top wall of the ring sleeve body is provided with a water passing hole, and the water passing hole communicates the mixing chamber and the microbubble generation chamber. The filter screen is located between the microbubble generation chamber and the water outlet at the bottom of the housing. The top wall of the ring sleeve body abuts against the circular ring body. A blocking block is provided on the top wall of the ring sleeve body. The water inlet member is fixed relative to the housing, and the ring sleeve body is rotatable relative to the housing. When the ring sleeve body rotates to the first position, the blocking block is staggered from the air suction hole. When the ring sleeve body rotates to the second position, the blocking block blocks the air suction hole.

[0007] The microbubble device according to the embodiment of the present invention has at least the following beneficial effects:

[0008] When the ring sleeve is in the first position, when water flows through the water inlet into the mixing chamber, due to the negative pressure, the suction holes start to suck air, and the air flow and water flow start to mix. The mixed water-vapor mixture enters the microbubble generation chamber through the water holes. In the microbubble generation chamber, most of the water-vapor mixture passes through the filter screen from different angles, thus forming microbubble water. A small part of the water-vapor mixture impacts the filter screen and rebounds. The rebounded water-vapor mixture reaches the filter screen again under the action of the wall of the microbubble generation chamber and forms microbubble water again after being cut by the filter screen. Finally, the microbubble water flows out from the water outlet. Rotate the ring sleeve to the second position, and the block plugs the suction holes. At this time, the water type changes from microbubble water to ordinary pure water. Due to the blockage of the filter screen, the water passing area of the filter screen is small, and the inside of the structure is easily filled with water, completely expelling the internal air. At this time, the flow rate of the pure water flowing out of the water outlet is slow and the direction is uniform, thus achieving a laminar flow effect and having a splash-proof function.

[0009] According to some embodiments of the present invention, a circumferential groove is provided at the bottom of the housing, and an arc-shaped limiting hole is provided at the bottom of the groove. The lower edge of the ring sleeve is embedded in the groove, and the ring sleeve can rotate along the groove. A switching rod is provided at the lower edge of the ring sleeve, and the switching rod is inserted into the limiting hole and can slide along the limiting hole.

[0010] According to some embodiments of the present invention, a water blocking chamber is further formed inside the ring sleeve. The water blocking chamber is located between the water passing holes and the microbubble generation chamber. The diameter of the water blocking chamber is smaller than the diameter of the microbubble generation chamber and larger than the diameter of the water passing holes.

[0011] According to some embodiments of the present invention, a plurality of suction holes are provided, which are circumferentially spaced along the ring body. Correspondingly, the number of the blocks is the same as the number of the suction holes, and the blocks are circumferentially distributed along the top wall of the ring sleeve.

[0012] According to some embodiments of the present invention, the diameter of the mixing chamber is the same as the diameter of the water passing holes, and the mixing chamber and the water passing holes are coaxially arranged.

[0013] According to some embodiments of the present invention, a plurality of water inlet holes are provided. The plurality of water inlet holes are all located above the mixing chamber, and a distance is left between each water inlet hole and the side wall of the mixing chamber.

[0014] According to some embodiments of the present invention, the shortest distance from the water inlet hole to the side wall of the mixing chamber is d 1 , the aperture of the water passing hole is d 2 , and at least one water inlet hole satisfies 0 < d 1 < 0.1d 2 .

[0015] According to some embodiments of the present invention, a sealing ring is circumferentially embedded at the top edge of the water inlet member.

[0016] According to some embodiments of the present invention, a plurality of ventilation holes are provided, and the plurality of ventilation holes are opened on the side wall of the housing and are circumferentially spaced apart along the housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Reference Figures 1-6 A microbubble device comprises a shell 100, a water inlet member 200, a sleeve body 300 and a filter screen 400. The water inlet member 200, the sleeve body 300 and the filter screen 400 are installed in the shell 100. The shell 100 is sleeve-shaped, and its outer wall has threads. The water inlet member 200 is disc-shaped, and the water inlet member 200 is embedded in the shell 100. The outer periphery of the water inlet member 200 and the shell 100 are clearance-matched. The shell 100 is provided with an air vent 110 for connecting the internal and external environments of the shell 100. The top wall of the water inlet member 200 is provided with a water inlet hole 210, and the lower end surface of the top wall is provided with a circular ring body 220. A mixing chamber 230 is surrounded by the circular ring body 220. The water inlet hole 210 is located above the mixing chamber 230, and the water inlet hole 210 is connected with the mixing chamber 230. The circular ring body 220 is provided with an air suction hole 221, and the air suction hole 22 1 is connected to the internal environment of the mixing chamber 230 and the shell 100, the annular sleeve body 300 is located below the water inlet member 200, a micro-bubble generating chamber 310 is formed inside the annular sleeve body 300, a water hole 320 is provided on the top wall of the annular sleeve body 300, the water hole 320 connects the mixing chamber 230 and the micro-bubble generating chamber 310, the filter screen 400 is located between the micro-bubble generating chamber 310 and the water outlet at the bottom of the shell 100, the top wall of the annular sleeve body 300 abuts against the annular body 220, a stopper 330 is provided on the top wall of the annular sleeve body 300, the water inlet member 200 is fixed relative to the shell 100, the annular sleeve body 300 is rotatable relative to the shell 100, when the annular sleeve body 300 rotates to the first position, the stopper 330 is staggered with the air suction hole 221, when the annular sleeve body 300 rotates to the second position, the stopper 330 blocks the air suction hole 221.

[0029] Working principle: When the annular sleeve body 300 is in the first position, when water flows into the mixing chamber 230 through the water inlet, the air inlet hole 221 starts to inhale due to negative pressure, and the air flow and water flow begin to mix. The mixed water-gas mixture passes through the water hole 320 and enters the microbubble generating chamber 310. In the microbubble generating chamber 310, most of the water-gas mixture passes through the filter screen 400 from different angles to form microbubble water. A small part of the water-gas mixture hits the filter screen 400 and rebounds. The rebounded water-gas mixture reaches the filter screen 400 again under the action of the cavity wall of the microbubble generating chamber 310, and is cut by the filter screen 400 to form microbubble water again, and finally the microbubble water flows out from the water outlet. Rotate the annular sleeve body 300 to the second position (such as Figure 6As shown), the block 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 400, the water flow area of ​​the filter 400 is small, and the interior of the structure is easily filled with water, and the internal air is completely removed. At this time, the flow rate of pure water flowing out of the water outlet is slow and the direction is uniform, thereby achieving a laminar flow effect and having a splash-proof effect.

[0030] In some embodiments of the present invention, a circle of grooves 120 are provided at the bottom of the housing 100 along the circumferential direction, and a circular arc-shaped limiting hole 121 is provided at the bottom of the groove 120. The lower edge of the annular sleeve body 300 is embedded in the groove 120, and the annular sleeve body 300 can rotate along the groove 120. A switching rod 340 is provided at the lower edge of the annular sleeve body 300, and the switching rod 340 is inserted into the limiting hole 121 and can slide along the limiting hole 121. The limiting hole 121 is a long hole that penetrates and is used to limit the rotation angle of the annular sleeve body 300. The switching rod 340 passes through the limiting hole 121. The user can toggle the switching rod 340 from the bottom of the housing 100 to rotate the annular sleeve body 300 to the second position. The two ends of the limiting hole 121 are respectively limited to the first position and the second position. It can be understood that the number of limiting holes 121 is not limited to one, and two or more limiting holes 121 can be provided along the circumference of the housing 100.

[0031] In some embodiments of the present invention, a water retaining cavity 350 is further formed inside the annular sleeve body 300, and the water retaining cavity 350 is located between the water hole 320 and the micro-bubble generating cavity 310, and the diameter of the water retaining cavity 350 is smaller than the diameter of the micro-bubble generating cavity 310 and larger than the diameter of the water hole 320. The water hole 320, the water retaining cavity 350 and the micro-bubble generating cavity 310 are coaxially arranged. Figure 5 As shown, a part of the water-gas mixture rebounding after hitting the filter screen 400 will hit the upper wall of the microbubble generating chamber 310 and then rebound to the filter screen 400. Since the distance between the upper wall of the microbubble generating chamber 310 and the filter screen 400 is not large, the speed at which the water-gas mixture returns to the filter screen 400 is still very fast, and microbubble water can still be formed. Another part of the water-gas mixture rebounding from the filter screen 400 will reach the water retaining chamber 350, and the upper wall of the water retaining chamber 350 will block the water from continuing to flow upward, preventing the backflow phenomenon under the low water pressure state. If the water retaining chamber 350 is not provided, under the same amount of water, more water will be concentrated and backflowed from the water hole 320. The present invention makes the diameter of the water retaining chamber 350 smaller than the microbubble generating chamber 310 and larger than the water hole 320, so that the ring sleeve body 300 is a stepped structure as a whole, which not only ensures that the speed of the water rebounding from the microbubble generating chamber 310 can form microbubbles, but also effectively prevents the backflow phenomenon under the low pressure state.

[0032] In some embodiments of the present invention, a plurality of air suction holes 221 are provided, which are circumferentially spaced along the circumferential direction of the toroidal body 220. Correspondingly, the number of the blocking blocks 330 is the same as that of the air suction holes 221, and the blocking blocks 330 are circumferentially distributed along the top wall of the ring sleeve body 300. The plurality of air suction holes 221 ensure sufficient air intake and avoid the problem of too high water flow intensity and too low microbubble content.

[0033] In some embodiments of the present invention, the diameter of the mixing chamber 230 is the same as that of the water passing hole 320, and the mixing chamber 230 and the water passing hole 320 are coaxially arranged. If the diameter of the water passing hole 320 is smaller than that of the mixing chamber 230, it may occur that the water flow is blocked by the side wall of the water passing hole 320 when flowing down from the water inlet hole 210, and the water flows out from the air suction hole 221. If the diameter of the water passing hole 320 is larger than that of the mixing chamber 230, the water blocking effect of the water blocking chamber 350 will be reduced.

[0034] In some embodiments of the present invention, a plurality of water inlet holes 210 are provided. The plurality of water inlet holes 210 are all located above the mixing chamber 230, and a distance is left between each water inlet hole 210 and the side wall of the mixing chamber 230. If the water inlet hole 210 is close to the side wall of the mixing chamber 230, the incoming water may flow along the side wall of the mixing chamber 230 to the air suction hole 221 and flow out from the air suction hole 221. A certain distance is left between the water inlet hole 210 and the side wall of the mixing chamber 230 to ensure that the water only flows downward.

[0035] In some embodiments of the present invention, as Figure 4 shown, the shortest distance from the water inlet hole 210 to the side wall of the mixing chamber 230 is d 1 , the aperture of the water passing hole 320 is d 2 , and at least one water inlet hole 210 satisfies 0 < d 1 < 0.1d 2 . Further, the plurality of water inlet holes 210 are circumferentially distributed along the mixing chamber 230, and each water inlet hole 210 satisfies 0 < d 1 < 0.1d 2 . In the low water pressure state, the impact force of the water is very weak, and most of the water may not pass through the filter net 400, and more water returns. At this time, the water blocking chamber 350 may also fail with a certain probability. If the shortest distance d 1 from the water inlet hole 210 to the side wall of the mixing chamber 230 is reduced, the flowing water will collide with the returning water, further preventing the backflow of water.

[0036] In some embodiments of the present invention, a sealing ring 500 is circumferentially embedded along the top edge of the water inlet member 200. Some bubblers in the prior art need to be assembled using snap fasteners. In the present invention, when assembling, the filter screen 400, the ring sleeve body 300, the water inlet member 200, and the sealing ring 500 are sequentially loaded into the housing 100, and finally the housing 100 is loaded into the water outlet device. This structure does not require snap fasteners, is simple to assemble, easy to disassemble, and convenient for cleaning the filter screen 400. It should be noted that the top wall of the ring sleeve body 300 and the water inlet member 200 are in normal abutment without being pressed tightly, and the contact between the two needs to ensure that the ring sleeve body 300 can rotate smoothly.

[0037] In some embodiments of the present invention, there are a plurality of vent holes 110, and the plurality of vent holes 110 are opened on the side wall of the housing 100 and are circumferentially spaced apart along the housing 100. The plurality of vent holes 110 ensure sufficient air intake.

[0038] A water outlet device includes the above-mentioned microbubble device.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
