Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring now to fig. 1-3, a microbubble generator 100 according to an embodiment of the present invention is described.

As shown in fig. 1 in conjunction with fig. 2 and 3, the microbubble generator 100 includes: a bubble generating member 10 and a waterway switch member 20.

In particular, the axial direction of the frothing member 10 defines a plurality of frothing waterways 11 and a plurality of normally open waterways 12.

The waterway switcher 20 is rotatably coupled to the foaming member 10 for selectively turning on or off the plurality of normally-on waterways 12. That is, the water path switching of the microbubble generator 100 can be realized by the rotation of the water path switching member 20.

The microbubble generator 100 has two types of water paths, and in the case where the bubbling water path 11 is activated, the water path switching member 20 closes the normally-open water path 12, so that the normally-open water path 12 does not output the use water to the outside. In the case where the normally-open waterway 12 is activated, the waterway conversion member 20 opens the normally-open waterway 12 so that the normally-open waterway 12 can output the use water to the outside. When the normal water passage 12 is opened, the bubbling water passage 11 may be closed or opened. That is, the microbubble generator 100 can externally output at least one of bubble water and normal water.

In short, according to the embodiment of the present invention, the microbubble generator 100 can satisfy different water requirements of users by defining the bubbling water path 11 and the normally open water path 12 in the axial direction of the bubbling member 10 and switching the water path by the rotation of the water path switching member 20, thereby providing convenience for the life of the users.

In some embodiments of the present invention, as shown in fig. 1, the waterway conversion member 20 has a fixing bracket 21 with both axial ends open. The fixed bracket 21 has water passages 211 and a support base 212 alternately arranged in the circumferential direction, and the support base 212 is provided with a valve stem 2121 for closing the normal water passage 12. The waterway conversion member 20 is configured to change the engagement between the stem 2121 and the normally-open waterway 12 during rotation, so that the normally-open waterway 12 is closed when the stem 2121 faces the outlet of the normally-open waterway 12, and the normally-open waterway 12 is opened when the stem 2121 is shifted from the normally-open waterway 12. Therefore, when the microbubble generator 100 is used, the normal water path 12 can be turned on or off only by rotating the water path switching member 20.

In order to ensure that the valve rod 2121 can effectively close the normally-open water passage 12, the end surface of the valve rod 2121 is spherical. When the valve stem 2121 is opposite to the normally-open water passage 12, the spherical surface of the valve stem 2121 seals the water outlet of the normally-open water passage 12.

In an alternative embodiment, as shown in fig. 1 in combination with fig. 2 and 3, the waterway conversion member 20 further includes: the packing 23, the packing 23 is set between the support base 212 and the foaming member 10, the packing 23 is set with a water passage hole 231 and a positioning hole 232, the valve rod 2121 passes through the positioning hole 232, the water passage hole 231 is communicated with the water passage 211. The packing 23 is interposed between the support base 212 and the foaming member 10, and the packing 23 can block water in the micro bubble generator 100 from permeating to the outside and is positioned on the support base 212 by the valve stem 2121 to prevent the packing 23 from displacing relative to the support base 212. When the fixing support 21 rotates, the sealing gasket 23 can be driven to rotate synchronously, and when the normal water passage 12 is opened, water flow can sequentially pass through the water through hole 231 and the water passage 211 and flow out.

In an alternative example, as shown in fig. 2 in conjunction with fig. 3, the frothing waterway 11 is located inside the frothing member 10, and the normal water passage 12 is located outside the frothing member 10 and surrounds the periphery of the frothing waterway 11. That is, the normally open water path 12 is dispersed in the circumferential direction of the bubbling water path 11, so that when the normally open water path 12 is opened, the water flow is not excessively concentrated, thereby preventing the water pressure from being high and the water flow from splashing around. In this embodiment, the gasket 23 not only can perform a sealing function, but also the water passing holes 231 dispersed in the gasket 23 can break up the water flow, thereby further reducing the water pressure of the water flow, i.e., the microbubble generator 100 can perform a function of reducing the water pressure of the normal water path 12.

Further, the normal water passage 12 passes through the water passage hole 231 of the packing 23 and enters the water passage 211, the water passage section of the normal water passage 12 is smaller than that of the water passage hole 231, and the water passage section of the water passage hole 231 is smaller than that of the water passage 211. That is, in the normal water passage 12, the cross section of the flow passage is gradually increased during the circulation process, so that the water pressure of the water flow is continuously reduced, and the water flow flowing out of the microbubble generator 100 is prevented from splashing around.

In an alternative example, as shown in fig. 1 in conjunction with fig. 2 and 3, a portion of the bubble generating member 10 protrudes into the fixing bracket 21. I.e. the frothing member 10 is embedded in the fixing bracket 21. The microbubble generator 100 further includes a limit structure that limits the bubble generating member 10 from being separated from the fixing bracket 21, and one of the hooks 2122 and the other one of the hooks 141 of the limit structure are slots 141. That is, the bubble former 10 is prevented from being separated from the fixing bracket 21 by the engagement of the hooks 2122 and the engaging grooves 141, and the stability of the engagement of the fixing bracket 21 and the bubble former 10 is improved.

In one particular embodiment, the blister 10 comprises: the outer end face of one end of the large diameter part 13 is supported on the supporting table 212, the small diameter part 14 penetrates through the sealing gasket 23, a clamping groove 141 is formed in the outer peripheral face of the small diameter part 14, a clamping hook 2122 is arranged at the inner end of the supporting table 212, and the clamping hook 2122 is clamped in the clamping groove 141. In other words, the foaming member 10 has a substantially T-shaped structure, is supported on the supporting base 212 by the large diameter portion 13, and prevents the foaming member 10 from being removed from the fixing bracket 21 by restricting the displacement of the foaming member 10 in the axial direction by the engagement of the hooks 2122 and the engaging grooves 141.

In a further alternative example, the water outlet end of the fixing bracket 21 is provided with a slow flow sheet 24, and the slow flow sheet 24 is formed with a plurality of water through holes 241. The water holes 241 of the slow flow sheet 24 can further disperse the water flow, so that the foaming water can generate more aerobic bubbles, and the residues on fruits and vegetables can be cleaned more effectively.

Further, the end face of the small diameter portion 14 and the buffering piece 24 are arranged at an interval, so that a buffering cavity is formed at the water outlet end of the micro-bubble generator 100, and when the water flow of the foaming water path 11 and the normal water path 12 flows to the buffering cavity, the flow speed of the water flow can be further slowed down.

In an embodiment of the present invention, the microbubble generator 100 further includes: the housing 30, the fixing bracket 21 and the slow flow sheet 24 are integrally formed in the housing 30. The outer shell 30 wraps the outer sides of the fixing support 21 and the slow flow sheet 24, so that the appearance structure of the micro-bubble generator 100 is more uniform and is easier to operate and clean, wherein the fixing support 21 and the outer shell 30 can be connected in an interference fit manner, and thus the fixing support 21 can be driven to rotate synchronously when the outer shell 30 is rotated, and the on-off of the normally-open water path 12 can be adjusted. The baffle 24 may optionally be removably attached to the housing 30 or the mounting bracket 21, thereby facilitating cleaning of the baffle 24.

In order to avoid water leakage between the fixing bracket 21 and the large diameter portion 13, the outer circumferential surface of the large diameter portion 13 may be provided with a positioning groove, a sealing ring 40 may be disposed in the positioning groove, and the sealing ring 40 is sandwiched between the outer circumferential surface of the large diameter portion 13 and the inner circumferential surface of the fixing bracket 21, so as to prevent the water leakage problem of the microbubble generator 100.

In some embodiments of the present invention, as shown in fig. 2 and 3, the bubbling waterway 11 includes an expanded diameter section 111 located upstream and a reduced diameter section 112 located downstream. That is, the upstream section of the foaming waterway 11 forms a diameter reducing cavity, and the downstream section of the foaming waterway 11 is an expanding cavity, so that water can be quickly introduced into the foaming waterway 11 through the diameter reducing cavity and sufficient air is introduced, and then the water pressure is released through the expanding cavity, so that the air is fully dissolved in the water flow to form high-concentration micro-nano foaming water. In order to ensure that the foaming water is fully formed in the foaming waterway 11, the length of the reducing section 112 is greater than that of the expanding section 111.

Optionally, the bubbling water path 11 is a venturi tube cavity, a cavitation effect is generated in the water flow venturi tube cavity, and the pressure is released instantaneously to form high-concentration micro-nano bubble water.

In order to facilitate the installation of the microbubble generator 100 on the water outlet end of the faucet or the water purifier or the water heater, the other end (e.g., the upper end in fig. 2) of the bubbling member 10 is exposed out of the fixing bracket 21, and the other end of the bubbling member 10 is connected to the fixing joint 50, and the fixing joint 50 is provided with an external thread.
