The invention provides a micro-bubble generating device.
In the embodiment of the present invention, as shown in fig. 1, the straight arrows in fig. 1 represent the flow direction of the water flow or the gas. The micro-bubble generating device comprises an air dissolving device 10, wherein the air dissolving device 10 is provided with an air dissolving cavity 11, and a water inlet 12, a water outlet 13 and an air inlet 14 which are communicated with the air dissolving cavity 11, the water outlet 13 is connected with a user water end, and the air inlet 14 is connected with an air source. Specifically, water from a water source flows into the air dissolving cavity 11 from the water inlet 12, air flows into the air dissolving cavity 11 from the air inlet 14, and a large amount of air is dissolved in the water in the high-pressure air dissolving cavity 11 and then flows out from the water outlet 13.
The micro-bubble generating device further comprises a first water inlet pipe 21, one end of the first water inlet pipe 21 is connected with a water source, and the other end of the first water inlet pipe 21 is connected with the water inlet 12, so that water at the water source flows into the dissolved air cavity 11 through the first water inlet pipe 21.
The microbubble generating device further comprises a first water outlet pipe 24, one end of the first water outlet pipe 24 is connected with the water outlet 13, the other end of the first water outlet pipe is connected with a user water using end, and water with a large amount of dissolved air flows out of the first water outlet pipe 24 for a user to use.
The micro-bubble generating device further comprises a bubble generator 52, the bubble generator 52 is arranged on the first water outlet pipe 24, and the bubble generator 52 is used for enabling water dissolved with a large amount of air to form micro-nano bubble water. Specifically, after the water dissolved with air passes through the bubble generator 52 at the rear end, because a water flow channel inside the bubble generator 52 forms a throat, when the water flows out through the throat, the pressure is released, and the mixed gas-liquid forms micro-nano bubble water after the pressure is released. The bubble generator 52 is similar to a flow restrictor, and because a great pressure difference exists between the water outlet end and the water inlet end of the bubble generator 52, when the gas-liquid mixed liquid flows from the water inlet end to the water outlet end of the bubble generator 52, the gas in the gas-liquid mixed liquid can be rapidly separated out from the liquid, so that a great amount of micro-nano bubbles can be generated. One, two or more bubble holes are provided in the bubble generator 52.
The microbubble generator further comprises an air inlet pipe 25, one end of the air inlet pipe 25 is connected with the air inlet 14, and the other end of the air inlet pipe 25 is used for being connected with an air source, such as an air tank or being directly connected with the outside. An air pump 53 is provided on the intake pipe 25 to pressurize the gas, thereby ensuring that the gas can be charged into the gas dissolving chamber 11. In addition, in order to prevent the reverse flow of gas and liquid in the gas-dissolving chamber 11, a check valve 54 may be provided on the inlet pipe 25 to prevent the gas and liquid from flowing out.
In the above, the water source refers to water from a tap water pipe, or the water source refers to water stored in a water tank or a water tank additionally provided. The water end for users refers to a water end for shower bath, a water end for hand washing, a water end for vegetable washing and the like.
Because the existing micro-bubble generating device has an air inlet cycle and a water outlet cycle, when a user needs to use bubble water, the user needs to enter the air inlet cycle first, namely, the air dissolving device 10 is inflated first, and no water flows out from the water end of the user in the process. And when the air inlet period is finished, the water outlet period is started. This microbubble generating device can not generate the microbubble in succession to seriously influence microbubble generating device's work efficiency, greatly reduced its practicality.
In this regard, the microbubble generator in the embodiment of the present invention further includes a second water inlet pipe 22, one end of the second water inlet pipe 22 is connected to a water source, and the other end is connected to a user water end, that is, the other end of the second water inlet pipe 22 is connected to the bubble generator 52. The micro-bubble generating device in the embodiment of the present invention is provided with two water inlet pipelines, namely a first water inlet pipe 21 and a second water inlet pipe 22, wherein one water inlet pipeline is used for dissolving gas, and the other pipeline directly provides domestic water, so as to realize different functions.
In addition, the microbubble generator according to the embodiment of the present invention further includes a switching device (for example, the first water inlet valve 41 and the second water inlet valve 42 in fig. 1, or the three-way valve 30 in fig. 2) for switching the first water inlet pipe 21 and the second water inlet pipe 22. Namely, the switching device has the following four working conditions: under a first working condition, the first water inlet pipe 21 is communicated with a water source, and the second water inlet pipe 22 is disconnected with the water source; under the second working condition, the first water inlet pipe 21 is disconnected with the water source, and the second water inlet pipe 22 is communicated with the water source; under a third working condition, the first water inlet pipe 21 and the second water inlet pipe 22 are respectively disconnected from a water source; in the fourth working condition, the first inlet pipe 21 and the second inlet pipe 22 are respectively communicated with the water source.
In the embodiment of the invention, when the bubble water is needed, the first water inlet pipe 21 can be controlled to be closed firstly, the air inlet 14 is controlled to be opened, namely, the water does not enter the air dissolving device 10 firstly, and the pressure in the air dissolving device 10 is smaller at the moment, so that even if the air pressure of the air inlet 14 is smaller, the air can be ensured to be smoothly filled into the air dissolving cavity 11. Thus, a less powerful air pump 53 may be used at the air inlet 14 to provide less pressurization of the gas. Thereby, it is possible to reduce power consumption while reducing the cost of the air pump 53.
Meanwhile, due to the addition of the second water inlet pipe 22, when the first water inlet pipe 21 is closed, the second water inlet pipe 22 can be controlled to be opened, so that the water of the water source flows from the second water inlet pipe 22 to the user water end. Because the water of the water source is mixed with partial air, and the gas enters the gas dissolving device 10 all the time, the original water in the gas dissolving device 10 is discharged to the water using end of the user under the pressure action of the gas, and a large amount of gas is dissolved in the water. Therefore, the water entering from the second water inlet pipe 22 and the water discharged from the air dissolving device 10 are mixed and then flow to the user water end together, and after passing through the bubble generator 52 arranged at the user water end, the gas in the water is released under the sudden change of the pressure, so that a large amount of micro-nano bubbles can be generated, and the requirement of the user on using bubble water is met.
In the embodiment of the present invention, the second water inlet pipe 22 is added, so that the air intake cycle and the water outlet cycle can be performed synchronously, that is, the second water inlet pipe 22 can be opened to provide bubble water for the user while the first water inlet pipe 21 is closed and the air dissolving cavity 11 is filled with air. This microbubble generating device can generate the microbubble in succession, improves microbubble generating device's work efficiency and practicality greatly.
In one embodiment, the microbubble generation device further includes a first water outlet pipe 24, one end of the first water outlet pipe 24 is connected to the water outlet 13, and the other end is connected to the user water end; the first water outlet pipe 24 is provided with a bubble generator 52. The first water outlet pipe 24 is arranged to enable the water outlet 13 of the air dissolving device 10 to be connected with a water end of a user to provide water with dissolved air for the user. In this embodiment, the second water inlet pipe 22 is connected to the first water outlet pipe 24, and the second water inlet pipe 22 is connected to the water inlet side of the bubble generator 52, so that the water flowing out from the second water inlet pipe 22 can be mixed with the water flowing out from the gas dissolving device 10, that is, more gas is dissolved in the water finally flowing to the bubble generator 52. In addition, the first outlet pipe 24 may be divided into a plurality of outlet branches, for example, some branches are connected to the shower head 55, some branches are connected to the kitchen faucet, the bathroom faucet, and the like, and the bubble generator 52 is disposed in some or all of the branches. Specifically, the microbubble generator further comprises a second water outlet pipe 26, wherein one end of the first water outlet pipe 24 is connected to the water outlet, and the other end is connected to the bubble generator; the second water outlet pipe 26 is connected with the first water outlet pipe 24, and the second water outlet pipe 26 is connected on a pipeline between the second water inlet pipe and the bubble generator. The second outlet pipe 26 may be connected to a shower head or a shower faucet, etc., and the water flowing out of the second outlet pipe 26 is non-bubble water. By turning on the water outlet switch of the first water outlet pipe 24 or the water outlet switch of the second water outlet pipe 26, a user can select to use bubble water or non-bubble water.
In one embodiment, the microbubble generator further includes a third water inlet pipe 23, one end of the third water inlet pipe 23 is connected to a water source, and the first water inlet pipe 21 and the second water inlet pipe 22 are respectively connected to the other end of the third water inlet pipe 23 to communicate with the water source through the third water inlet pipe 23. In this embodiment, the water inlet end of the third water inlet pipe 23 is connected to a water source, and the water outlet end of the third water inlet pipe 23 is connected to the first water inlet pipe 21 and the second water inlet pipe 22, that is, the water in the water source is divided into two paths when reaching the water outlet end of the third water inlet pipe 23, wherein one path flows into the air dissolving device 10 through the first water inlet pipe 21, and the other path directly flows out through the second water inlet pipe 22 for the user to use, thereby realizing the continuous water use of the user.
In order to improve the gas-liquid mixing efficiency and the gas dissolving rate and to improve the water inlet pressure as much as possible, a booster pump (not shown) is arranged on the third water inlet pipe 23. The booster pump is arranged to increase the water outlet pressure of the third water inlet pipe 23, so that when the pressure in the gas dissolving device 10 is large, the pressurized water flow can smoothly flow into the gas dissolving device 10. In addition, the water outlet pressure of the second water inlet pipe 22 can be increased, and when water flows through the bubble generator 52, the water pressure difference between the water inlet side and the water outlet side of the bubble generator 52 can be increased, so that the water pressure changes suddenly, more gas is released, and more and finer bubbles are formed. Simultaneously, set up the booster pump at third inlet tube 23, can satisfy the pressure boost of first inlet tube 21 and second inlet tube 22 simultaneously, be favorable to reducing the use of booster pump.
The third water inlet pipe 23 is provided with a water flow sensor 51, when a user uses water at the water end, that is, when the water outlet tap or the water outlet switch is turned on, water from a water source flows into the third water inlet pipe 23, and the water flow sensor 51 detects that water flows through, so that the on-off of the first water inlet valve 41 and the second water inlet valve 42 is controlled, and the air pump 53 at the air inlet 14 is controlled to work or stop working, and the like.
In an embodiment, a liquid level sensor (not shown) is disposed in the air-dissolving chamber 11, and the liquid level sensor is specifically a float, an infrared sensor, or the like. The liquid level sensor can detect the liquid level in the dissolved air cavity 11.
The switching device in the embodiment of the present invention is specifically a valve, and the following two embodiments are taken as examples and are not limited thereto, as long as the on/off of the first water inlet pipe 21 and the second water inlet pipe 22 can be satisfied.
Referring to fig. 2, in an embodiment, the switching device is a three-way valve 30, and the three-way valve 30 is connected to the first water inlet pipe 21, the second water inlet pipe 22 and the third water inlet pipe 23 respectively. The three-way valve 30 can conduct the first water inlet pipe 21 and the third water inlet pipe 23; and/or the three-way valve 30 can conduct the second water inlet pipe 22 and the third water inlet pipe 23.
Optionally, the three-way valve 30 is a two-position three-way valve 30, and the three-way valve 30 is a solenoid valve, so as to facilitate automatic control. The three-way valve 30 has a water inlet 31, a first outlet 32 and a second outlet 33, the water outlet of the third inlet pipe 23 is connected to the water inlet 31, the water inlet of the first inlet pipe 21 is connected to the first outlet 32, and the water inlet of the second inlet pipe 22 is connected to the second outlet 33. The three-way valve 30 has the following various operating conditions: in the first working condition, the first outlet 32 is communicated with the water inlet 31, and the second outlet 33 is disconnected with the water inlet 31; in the second working condition, the first outlet 32 is disconnected from the water inlet 31, and the second outlet 33 is communicated with the water inlet 31; in the third condition, the first outlet 32 and the second outlet 33 are both disconnected from the water inlet 31. Furthermore, the three-way valve 30 may have a fourth operating condition in which the first outlet 32 and the second outlet 33 are each in communication with the water inlet 31.
Specifically, the working process of the microbubble generation device for generating the bubble water is as follows:
determining that a bubble water use instruction is received;
controlling the first water inlet valve to be closed, the second water inlet valve to be opened and the air inlet to admit air;
determining that the liquid level in the dissolved air cavity is reduced to a preset value;
and controlling the first water inlet valve to be opened, closing the second water inlet valve and stopping air inlet.
The above-described process of generating bubble water is explained in detail as follows:
detecting and judging signals: the water tap on the branch where the bubble generator 52 is located is turned on, the third water inlet pipe 23 is filled with water, water flow sends a water flow signal to the controller 70 of the micro-bubble generating device through the water flow sensor 51, at the moment, the controller acquires a water using instruction of bubble water, and the controller 70 controls the micro-bubble generating device to enter an air intake and water drainage process.
And (3) air inlet and water drainage processes: the controller 70 controls the three-way valve 30 to be powered on, and simultaneously the first outlet 32 of the three-way valve 30 is disconnected from the water inlet 31, and the second outlet 33 is connected to the water inlet 31, that is, no water is supplied to the gas dissolving device 10 at this time. In addition, the air pump 53 on the air inlet pipe 25 operates, the air is pressurized under the action of the air pump 53 and is continuously sent into the air dissolving cavity 11, the original water in the air dissolving cavity 11 is discharged from the water outlet 13 under the action of the air pressure, and therefore the air gradually fills the whole air dissolving cavity 11. In addition, during the air intake and water discharge process, because the water in the third water inlet pipe 23 flows to the second water inlet pipe 22, the water in the second water inlet pipe 22 and the water discharged from the air dissolving chamber 11 are mixed in the first water outlet pipe 24 and then flow through the bubble generator 52 together, and bubbles can be generated to generate bubble water under the action of the bubble generator 52, thereby ensuring the continuity of water use for users.
The process of generating micro-nano bubble water: after some or all of the gas is present in the gas dissolving cavity 11, that is, after all or some of the water in the gas dissolving cavity 11 is discharged, the air pump 53 stops operating. In this process, the liquid level sensor detects the liquid level in the air-dissolving chamber 11, and when the liquid level falls to a predetermined value, for example, 0 or above 0, the operation of the air pump 53, that is, the air intake is stopped. Then, the controller 70 controls the second outlet 33 of the three-way valve 30 to be disconnected from the water inlet 31 and the first outlet 32 to be connected to the water inlet 31, and at this time, the water introduced from the third water inlet pipe 23 flows entirely through the first water inlet pipe 21 and flows to the air-dissolving chamber 11. When the air inlet 14 is closed and the first outlet 32 is communicated with the water inlet 31, the pressure in the air dissolving chamber 11 is consistent with the water inlet pressure of the water inlet 12, and the water flowing out of the first outlet 32 is pressurized by the booster pump before, so the water pressure is high. Thus, in the high-pressure air-dissolving chamber 11, air is largely dissolved in water. After the saturated high-pressure water dissolved with air flows to the bubble generator 52 through the first water outlet pipe 24 at the rear end, the mixed gas and liquid are released by pressure to form micro-nano bubble water.
The circulation process is as follows: after all the air in the air dissolving cavity 11 is dissolved in water, the air is recycled to the air intake and water discharge process, and the process is repeated.
In the above, in the process of generating micro-nano bubble water, when the first outlet 32 is communicated with the water inlet 31, the second outlet 33 can also be continuously communicated with the water inlet 31, that is, part of water flows to the gas dissolving chamber 11, and the other part of water directly flows out.
In addition, the microbubble generation device also has other work flows, such as a shower water work flow:
determining that a shower water use instruction is received;
the first water inlet valve is controlled to be closed, and the second water inlet valve is controlled to be opened.
The shower water work flow is specifically explained as follows:
upon receipt of the shower water command, indicating that bubble water is not required to be used, the air pump 53 stops operating and either or both of the first outlet 32 and the second outlet 33 are kept in a conductive state with the water inlet 31. In this process, the bubble generator 52 may be provided in the outlet branch of the shower water to generate bubble water, or the bubble generator 52 may not be provided so that the water flows out directly.
Referring to fig. 1 again, in an embodiment, the switching device includes a first inlet valve 41 and a second inlet valve 42, the first inlet valve 41 is disposed on the first inlet pipe 21, and the second inlet valve 42 is disposed on the second inlet pipe 22. The working process in this embodiment is substantially the same as that of the three-way valve 30, wherein during the air intake and drainage process, the first water inlet valve 41 is disconnected, so that the first water inlet pipe 21 is disconnected from the third water inlet pipe 23; the second inlet valve 42 is conducted so that the second inlet pipe 22 is conducted with the third inlet pipe 23. When micro-nano bubble water is generated, the first water inlet valve 41 is switched on, and the second water inlet valve 42 is switched off.
To increase the air solubility, the water inlet 12 may be provided with jets or multiple streams of water to increase the contact of the water with the air. Specifically, the water inlet 12 has a plurality of water inlets arranged at intervals, that is, water is divided into a plurality of small water flows by the plurality of water inlets, so that the contact area with gas can be increased, and the gas dissolving rate is improved. Or, the water inlet 12 is provided with an ejector, which may be a venturi ejector, so that the water flowing out of the ejector may be sprayed out with sudden change of pressure, i.e., pressure drop, and the water flow during spraying may be rapidly dispersed, thereby increasing the contact area with the gas.
To ensure that the gas is better dissolved in the water and to avoid gas spillage, in one embodiment, the water inlet 12 and the gas inlet 14 are arranged at the top of the gas-dissolving chamber 11 and the water outlet 13 is arranged at the bottom of the gas-dissolving chamber 11. Therefore, when water exists in the air dissolving cavity 11, the water blocks the water outlet 13 at the bottom, and the independent air is prevented from escaping. And the water inlet 12 sets up at the top for water flows from the top down, and air inlet 14 sets up at the top, makes gaseous scattered flow all around in dissolving gas chamber 11, better fully fuses with gas in the in-process that water flows from the top down.
The integral device of the microbubble generation device in the embodiment of the invention has simple structure and lower cost. In addition, the micro-bubble generating device is integrally modularized, has small volume and light weight, can be designed into different volumes according to requirements, and can be used for different life scenes and assembled on different household equipment for application. For example, the microbubble generator can be used in household appliances such as gas water heaters, electric water heaters, water purifiers, beauty instruments, and dishwashers (water-containing tank dishwashers), and thus the cleaning efficiency of the household appliances can be improved.

The present invention further provides a water heater, which includes a microbubble generator, and the detailed structure of the microbubble generator refers to the above embodiments, and since the water heater employs all the technical solutions of all the above embodiments, the water heater at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.
Referring to fig. 3 and 4, the switching device in fig. 3 includes a first inlet valve 41 and a second inlet valve 42, and the switching device in fig. 4 is a three-way valve 30.
The water heater comprises a shell and a heat exchange device 60, the heat exchange device 60 is arranged in the shell, the heat exchange device 60 is provided with a normal-temperature water inlet and a hot water outlet, the normal-temperature water inlet is connected with a water source, the hot water outlet is connected with the water inlet end of a third water inlet pipe 23 of the micro-bubble generating device, and the first water inlet pipe 21 and the second water inlet pipe 22 are connected with the hot water outlet through the third water inlet pipe 23; or, the third water inlet pipe 23 is connected to the normal temperature water inlet, so that the normal temperature water inlet is connected to the water source through the third water inlet pipe 23, and the first and second water inlet pipes 21 and 22 are respectively connected to the hot water outlet. Specifically, the water heater may be a gas water heater or an electric water heater, and the heat exchange device 60 specifically refers to a heat exchange tube or a heating liner, and generally, gas in the gas water heater heats the heat exchange tube, so that water flows into the third water inlet tube 23 after being heated, and then flows from the first water inlet tube 21 or the second water inlet tube 22 to the user water end. In the electric water heater, an electric heating tube is provided in the heating inner container to heat the water in the inner container, and the heated water also flows to the third water inlet pipe 23.
In the prior water heater, because the second water inlet pipe 22 is not arranged, water from a water source firstly flows into the air dissolving device 10 and is mixed with original water in the air dissolving device 10, and simultaneously, air is dissolved in the water and flows to a water end of a user. If the original water in the air dissolving device 10 is more, the water from the water source flows into the air dissolving device 10 after being heated in a longer time, and the influence on the water temperature in the air dissolving device 10 is smaller, namely the temperature of the water flowing out from the water end of a user in a longer time is lower, thus bringing great inconvenience to the user.
In view of this, in the embodiment of the present invention, by additionally providing the second water inlet pipe 22, the first water inlet pipe 21 and the second water inlet pipe 22 of the micro-bubble generating device are respectively connected to the hot water outlet, and hot water can be provided through the second water inlet pipe 22 in the initial stage of generating bubble water by the micro-bubble generating device, meanwhile, the original water in the air dissolving device 10 slowly flows out from the water outlet 13 and is mixed with the hot water in the second water inlet pipe 22, and the water mixed into the first water outlet pipe 24 in the air dissolving device 10 per unit time is less, so that the temperature influence on the hot water flowing in the second water inlet pipe 22 is less, and the water temperature at the water using end of a user can be prevented from being too low. After all the water in the air dissolving device 10 is discharged, the first water inlet pipe 21 is filled with water, and at this time, all the air dissolving device 10 is hot water, so that when the user water end is completely provided with hot water by the air dissolving device 10, the water temperature of the user water end is high. Therefore, in the embodiment of the invention, by arranging the first water inlet pipe 21 and the second water inlet pipe 22 and switching and controlling the two water paths, sudden changes of water flow and temperature can be eliminated, and the comfort is improved.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
