Description

Technical Field

[0001] The present invention relates to the technical field of micro-bubble water production devices, and in particular to a micro-bubble water production device. Background Art

[0002] Microbubbles are tiny bubbles with a diameter of less than 50 μm. Microbubble water is primarily produced through a pressure-differential mixing process. This involves thoroughly mixing a gas (such as air) with water under a certain pressure to form a gas-water solution. The pressure is then released through expansion, causing the gas dissolved in the water to suddenly aggregate into tiny microbubbles, resulting in a milky white appearance. This process alters the mixing state of the gas and water, a physical change. This water has a strong decontamination function and is used in industry to treat wastewater. It also plays a role in aquaculture and improving the ecological environment. In daily life, it is commonly used for washing, among other things.

[0003] Existing microbubble water is typically produced using a microbubble water production device, which typically consists of three main components: a water booster, an air supply device, and a gas-liquid mixer. These components are connected by pipes and specialized connectors. The operating principle is as follows: water passes through the water booster and external air, which passes through the air supply device, enters the gas-liquid mixer. The high pressure in the gas-liquid mixer thoroughly mixes and compresses the water and air. Finally, the water passes through a specialized outlet valve to produce microbubble water. However, existing microbubble water production devices produce suboptimal microbubble water and are unable to produce microbubble water consistently. Summary of the Invention

[0004] The object of the present invention is to provide a microbubble water production device to solve the problem that the microbubble water produced by the existing microbubble water production device has poor effect.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A microbubble water production device includes a gas-liquid mixer. The upper portion of the gas-liquid mixer is provided with an interface. Water and gas are introduced through the interface. The introduced water mixes with gas maintained at a certain pressure in the gas-liquid mixer to form microbubble water.

[0007] Preferably, the interface is provided with a preliminary mixing device connected thereto, and water and gas are preliminarily mixed by the preliminary mixing device and then enter the gas-liquid mixer through the interface;

[0008] Alternatively, there are two interfaces, one of which is used to introduce gas and the other is used to introduce water, and the gas and water enter the gas-liquid mixer respectively through the interfaces.

[0009] As a preference, it further comprises a water pump,

[0010] When there is one interface, the water pump is used to deliver water to the preliminary mixing device;

[0011] When there are two interfaces, the water pump is used to transport water to the gas-liquid mixer through the interfaces.

[0012] Preferably, a first one-way valve which is conductive along the water inlet direction is provided on one side of the water pump.

[0013] As an advantage, it also includes an air pump,

[0014] When there is only one interface, the air pump is used to deliver gas to the preliminary mixing device;

[0015] When there are two interfaces, the air pump is used to deliver gas to the gas-liquid mixer through the interfaces.

[0016] Preferably, a second one-way valve which is openable in the air intake direction is provided on one side of the air pump.

[0017] Preferably, a liquid level detection unit is provided in the gas-liquid mixer, and the liquid level detection unit includes a first detection probe and a second detection probe which are arranged in descending order and correspond to a liquid level detection point respectively;

[0018] Alternatively, the liquid level detection unit includes a first detection probe, a second detection probe, and a third detection probe, which are arranged in descending order and correspond to a liquid level detection point respectively.

[0019] Preferably, a third one-way valve with a conducting direction opposite to that of the first one-way valve is connected in parallel on both sides of the water pump, and the opening pressure of the third one-way valve is greater than the pressure at the liquid level detection point corresponding to the second detection probe.

[0020] Preferably, an electrically controlled stop valve is provided between the first one-way valve and the water pump.

[0021] Preferably, a pressure relief valve is provided at the upper end of the gas-liquid mixer.

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] Example 1

[0030] This embodiment provides a micro bubble water production device, such as Figure 1 As shown, the microbubble water production device includes a sealed gas-liquid mixer 1. Two interfaces are provided at the top of the gas-liquid mixer 1, and a water outlet is provided at the bottom. Each of the two interfaces is connected to a pipe joint 14, one for introducing water and the other for introducing gas. The water outlet is connected to a water outlet valve 12.

[0031] The above-mentioned two pipe joints 14 are respectively connected to the water inlet pipe 2 and the air inlet pipe 3. Water flows in the water inlet pipe 2 and gas flows in the air inlet pipe 3. The water in the water inlet pipe 2 and the gas in the air inlet pipe 3 can be transported to the gas-liquid mixer 1, and the water transported to the gas-liquid mixer 1 can be mixed with the gas maintained at a certain pressure in the gas-liquid mixer 1 to form microbubble water, and the microbubble water can maintain a certain liquid level in the gas-liquid mixer and be continuously output through the water outlet valve 12.

[0032] A first one-way valve 4 and a water pump 5 are provided on the water inlet pipe 2. Water is delivered by the water pump 5 through the water inlet pipe 2 and the pipe joint 14 to the gas-liquid mixer 1. The first one-way valve 4 is openable in the water inlet direction and can be located on one side of the water pump 5, for example, on the left side of the water pump 5 as shown, or on the right side of the water pump 5, to prevent water from flowing back.

[0033] The water pump 5 is connected to a controller (not shown) of the microbubble water production device. In this embodiment, the water pump 5 may have a pressurizing function (e.g., a high-pressure water pump) to deliver water to a preset pressure. The water pump 5 may also be another device capable of delivering water at a preset pressure.

[0034] An air pump 6 and a second one-way valve 7 are provided on the air intake pipe 3. Gas is delivered from the air pump 6 to the gas-liquid mixer 1 through the air intake pipe 3 and the pipe joint 14. The second one-way valve 7 is openable in the air intake direction and can be located on one side of the air pump 6, for example, on the upper side of the air pump 6 as shown, or on the lower side of the air pump 6, to prevent backflow of gas.

[0035] The air pump 6 is connected to the controller. In this embodiment, the air pump 6 can be a pump with a pressurizing function (such as a high-pressure air pump) so that the delivered gas reaches a preset pressure. The air pump 6 can also be other devices capable of delivering gas at a preset pressure.

[0036] This embodiment employs two pipe connectors 14 positioned at two interfaces on the upper portion of a gas-liquid mixer 1. The water inlet pipe 2 and the air inlet pipe 3 are then connected to the two pipe connectors 14. Water is then pumped into the gas-liquid mixer 1 via a water pump 5, while gas is simultaneously pumped into the mixer 1 via an air pump 6. The water mixes with the gas maintained at a constant pressure within the mixer 1 to form microbubble water. This microbubble water maintains a constant liquid level within the mixer 1 and is continuously discharged through the bottom outlet. This method produces microbubble water with a higher degree of air incorporation, resulting in better results and continuous production.

[0037] In this embodiment, a pressure relief valve 11 is further provided at the upper end of the gas-liquid mixer 1. When the pressure in the gas-liquid mixer 1 reaches the pressure relief value of the pressure relief valve 11, the pressure relief valve 11 can be used to relieve the pressure to ensure the safety of the gas-liquid mixer 1.

[0038] In this embodiment, an electrically controlled stop valve 10 is further provided between the first one-way valve 4 and the water pump 5. The electrically controlled stop valve 10 is connected to the controller. When the microbubble water output effect is not obvious or is not used for a long time, the water in the gas-liquid mixer 1 needs to be discharged. At this time, the water inlet pipe 1 is disconnected by the electrically controlled stop valve 10, and then the water in the gas-liquid mixer 1 is discharged from the water outlet valve 12 under the pressure in the gas-liquid mixer 1, or the air pump 6 can be controlled to supply air to the gas-liquid mixer 1 to discharge the water in the gas-liquid mixer 1.

[0039] Example 2

[0040] This embodiment is improved on the basis of the first embodiment. Specifically, Figure 2As shown, the gas-liquid mixer 1 of this embodiment is provided with an interface, and correspondingly, a pipe joint 14 is also provided. A preliminary mixing device 13 is connected to the pipe joint 14 through a pipeline. The preliminary mixing device 13 is respectively connected to the water inlet pipeline 2 and the air inlet pipeline 3. Water is transported to the preliminary mixing device 13 through the water pump 5 and flows into the gas-liquid mixer 1 through the preliminary mixing device 13.

[0041] Similarly, the gas is transported to the preliminary mixing device 13 via the air pump 6 and preliminarily mixed with the water transported by the water pump 5 in the preliminary mixing device 13. The mixed water and gas are then transported by the preliminary mixing device 13 to the gas-liquid mixer 1, where they mix with the gas maintained at a certain pressure in the gas-liquid mixer 1 to form microbubble water. Moreover, the microbubble water can maintain a certain liquid level in the gas-liquid mixer 1 and be continuously output through the water outlet valve 12.

[0042] In this embodiment, the preliminary mixing device 13 is selected as an ejector. When the water pump 5 and the air pump 6 are turned on, the water delivered by the water pump 5 and the gas delivered by the air pump 6 are delivered to the ejector and mixed in the ejector. The ejector is then delivered to the gas-liquid mixer 1. In addition, in this embodiment, the ejector itself has a negative pressure adsorption function. When the water pump 5 delivers water to the ejector, the ejector generates a negative pressure, and the gas delivered by the air pump 6 is quickly adsorbed therein by the negative pressure, and preliminarily mixed with the water delivered by the water pump 5. The preliminarily mixed water and gas are then delivered to the gas-liquid mixer 1, further improving the mixing degree of the gas and water, making the gas-liquid ratio in the gas-liquid mixer 1 more reasonable, and generating micro-bubble water with better effect.

[0043] It can be understood that in this embodiment, the above-mentioned preliminary mixing device 13 can also be replaced by other devices that can achieve preliminary mixing of water and gas, and not all of them need to have a negative pressure function. Other devices that can achieve preliminary mixing of water and gas in the prior art are also within the protection scope of this embodiment.

[0044] In this embodiment, a liquid level detection unit 8 is provided in the gas-liquid mixer 1. The liquid level detection unit 8 detects at least two liquid level detection points from high to low. For example, this embodiment can detect two liquid level detection points. Specifically, Figure 2 As shown, the liquid level detection unit 8 includes a first detection probe 81 and a second detection probe 82 arranged from high to low. The two detection probes correspond to two liquid level detection points respectively, which are used to detect whether the liquid in the gas-liquid mixer 1 reaches the liquid level detection point.

[0045] Because the water pump of an existing gas-liquid mixer needs to be shut down after the internal pressure reaches the set value, and then the water outlet valve of the gas-liquid mixer is frequently opened during use, the water pump needs to be started again when the pressure inside the gas-liquid mixer falls below the set value. Frequent opening and closing of the water outlet valve during use will cause the water pump to start frequently, which will shorten the service life of the water pump. In addition, when the water line is under high pressure, starting the water pump will cause it to stall, causing the water pump motor to heat up, seriously shortening the service life of the water pump.

[0046] Based on the above reasons, this embodiment has a third one-way valve 9 connected in parallel on both sides of the water pump 5 in the opposite direction of the first one-way valve 4. The opening pressure of the third one-way valve 9 is greater than the pressure at the liquid level detection point corresponding to the second detection probe 82. When the pressure in the gas-liquid mixer 1 is greater than the opening pressure of the third one-way valve 9, the third one-way valve 9 will be turned on. At this time, the water flowing out after being pressurized by the water pump 5 will flow from the third one-way valve 9 to the inlet of the water pump 5 and continue to circulate by the water pump 5 without entering the gas-liquid mixer 1, thereby avoiding excessive pressure in the gas-liquid mixer 1. In addition, the provision of the third one-way valve 9 can reduce the frequency of starting and closing the water pump 5, thereby extending the service life of the water pump 5.

[0047] When the microbubble water production device of this embodiment is in operation, first, the water pump 5 and the air pump 6 are controlled to respectively introduce water and air into the preliminary mixing device 13. Subsequently, after preliminary mixing in the preliminary mixing device 13, the water and air are transported to the gas-liquid mixer 1 through the top pipe joint 14, and mixed with the gas maintained at a certain pressure in the gas-liquid mixer 1 to form microbubble water. Moreover, the microbubble water can maintain a certain liquid level in the gas-liquid mixer 1 and be continuously output through the water outlet valve 12. The microbubble water generated in this way has a higher degree of air integration, thereby improving the cleaning effect of the microbubble water and meeting the requirements of users.

[0048] Furthermore, this embodiment also detects the liquid level within the gas-liquid mixer 1 using a detection probe of the liquid level detection unit 8. When the liquid level within the gas-liquid mixer 1 falls below the second set value corresponding to the second detection probe 82, the second detection probe 82 provides a feedback signal to the controller, which activates the water pump 5. The water pump 5 delivers water to the preliminary mixing device 13. Simultaneously, the air pump 6 is activated to introduce air into the preliminary mixing device 13. Under the action of the preliminary mixing device 13, the water delivered by the water pump 5 and the gas delivered by the air pump 6 undergo a preliminary mixing process. The preliminarily mixed water and gas flow through the preliminary mixing device 13 into the gas-liquid mixer 1, where they mix with the gas maintained at a certain pressure within the gas-liquid mixer 1 to form microbubble water. When the water pump 5 is activated, the controller records the operating time T of the water pump 5. As the water pump 5 and the air pump 6 continue to operate, the liquid level within the gas-liquid mixer 1 reaches the second set value corresponding to the second detection probe 82.

[0049] When the above-mentioned liquid level reaches the second set value corresponding to the second detection probe 82, the second detection probe 82 feeds back a signal to the controller, and the controller determines whether the running time T of the water pump 5 is greater than or equal to the set water inlet time T1. If the running time T of the water pump 5 is greater than or equal to the set water inlet time T1, it means that the pressure in the gas-liquid mixer 1 has reached the required pressure. At this time, the controller turns off the water pump 5 and the air pump 6.

[0050] If the running time T is less than the set water inlet time T1, even though the liquid level reaches the second set value corresponding to the second detection probe 82, the pressure in the gas-liquid mixer 1 may not reach the required pressure. In this case, the controller controls the water pump 5 to continue to inlet water until the set water inlet time T1, and the air pump 6 is turned off.

[0051] As water pump 5 continues to pump water until the set water inlet time T1, while the pressure within gas-liquid mixer 1 is less than the opening pressure of third one-way valve 9, water pump 5 continues to pump water into gas-liquid mixer 1. When the pressure within gas-liquid mixer 1 exceeds the opening pressure of third one-way valve 9, the water pumped by water pump 5 flows through third one-way valve 9 to the inlet of water pump 5, circulating. At this point, water pump 5 no longer pumps water into gas-liquid mixer 1, and the pressure within gas-liquid mixer 1 remains constant. The circulating water pumped by water pump 5 also reduces the frequency of its on-off operation, thereby extending the service life of water pump 5.

[0052] In this embodiment, when the above-mentioned third one-way valve 9 fails, if the liquid level in the gas-liquid mixer 1 reaches the third set value corresponding to the first detection probe 81, the first detection probe 81 feeds back a signal to the controller, the controller turns off the water pump 5, and issues an alarm through the display or buzzer to remind the user that the pressure in the gas-liquid mixer 1 is too high and needs to be drained in time to avoid the pressure in the gas-liquid mixer 1 being too high, affecting the safety performance of the gas-liquid mixer 1.

[0053] Furthermore, when the liquid level detection unit 8 fails and cannot detect the third set value or the controller fails, there is continuous water inflow from the water pump 5, and the pressure in the gas-liquid mixer 1 becomes larger and larger. When the pressure in the gas-liquid mixer 1 reaches the pressure relief pressure value of the pressure relief valve 11, the pressure can be relieved through the pressure relief valve 11 so that the pressure in the gas-liquid mixer 1 no longer rises, thereby avoiding excessive pressure in the gas-liquid mixer 1 affecting safe use.

[0054] Example 3

[0055] This embodiment provides a microbubble water production device, which differs from the second embodiment in that the liquid level detection unit 8 of this embodiment includes a first detection probe 81, a second detection probe 82 and a third detection probe 83 arranged in descending order, as shown in FIG. Figure 3As shown, the three detection probes correspond to three liquid level detection points respectively, which are used to detect whether the liquid in the gas-liquid mixer 1 reaches the liquid level detection points.

[0056] Through the above-mentioned third detection probe 83, when the liquid level reaches the position of the second detection probe 82, and the running time T is greater than or equal to the set water inlet time T1, after the water pump 5 and the air pump 6 are turned off, when the user uses microbubble water, the liquid level will drop to between the third detection probe 83 and the second detection probe 82. At this time, the water pump 5 will not start until the liquid level drops to the position of the third detection probe 83 or below, and the water pump 5 and the air pump 6 are controlled to intake water and air into the preliminary mixing device 13. After preliminary mixing by the preliminary mixing device 13, the water enters the gas-liquid mixer 1, and the above process is repeated until the liquid level reaches the position of the second detection probe 82.

[0057] When the microbubble water production device of this embodiment is in operation, based on the second embodiment, if the liquid level reaches the second set value corresponding to the second detection probe 82 and the operating time T is greater than or equal to the set water inlet time T1, the water pump 5 and the air pump 6 are turned off. When the user uses the microbubble water, the liquid level will drop to between the third detection probe 83 and the second detection probe 82. At this time, the water pump 5 will not start until the liquid level drops to or below the first set value corresponding to the third detection probe 83. The water pump 5 and the air pump 6 are then controlled to feed water and air into the preliminary mixing device 13. After preliminary mixing in the preliminary mixing device 13, the water and air enter the gas-liquid mixer 1. The above process is repeated until the liquid level reaches the second set value corresponding to the second detection probe 82.

A person skilled in the art would be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all embodiments here.
