The pipe joint 14 is connected with a preliminary mixing device 13 through a pipe, the preliminary mixing device 13 is used for preliminarily mixing water and gas, conveying the preliminarily mixed water and gas into the gas-liquid mixer 1 through the pipe joint 14 and the inlet, and mixing the preliminarily mixed water and gas with the gas maintaining a certain pressure in the gas-liquid mixer 1 again to form micro-bubble water, and the micro-bubble water can maintain a certain liquid level in the gas-liquid mixer and is continuously output through the water outlet and the drain valve 12. In this embodiment, the preliminary mixing device 13 may be a jet device, or may be another device capable of achieving preliminary mixing of water and gas.
Above-mentioned preliminary mixing arrangement 13 is connected with water intake pipe 2 and air inlet pipe 3 respectively, wherein:
the water inlet pipeline 2 is provided with a first one-way valve 4 and a water pump 5, and water is conveyed into the preliminary mixing device 13 through the water inlet pipeline 2 by the water pump 5. The first check valve 4 is configured to be conductive in the water inlet direction, and may be located on one side of the water pump 5, for example, on the left side of the illustrated water pump 5, or on the right side of the water pump 5, for preventing the water from flowing backwards. The water pump 5 is connected to a controller (not shown) of the micro bubble water generating apparatus. In this embodiment, the water pump 5 may have a pressurizing function (e.g., a high-pressure water pump) so that the delivered water reaches a predetermined pressure, and the water pump 5 may be other devices capable of delivering water at a predetermined pressure.
Be equipped with air pump 6 and second check valve 7 on air inlet pipeline 3, above-mentioned air pump 6 is connected in above-mentioned controller, and is gaseous in air pump 6 carries to preliminary mixing device 13 through air inlet pipeline 3 to carry out the preliminary mixing of gas and water by preliminary mixing device 13. The second check valve 7 is conductive in the air intake direction and may be located at one side of the air pump 6. In this embodiment, the air pump 6 may be a pump having a pressurization function (e.g., a high-pressure air pump) so that the delivered air reaches a predetermined pressure, and the air pump 6 may be another device capable of delivering air at a predetermined pressure.
In this embodiment, by the above preliminary mixing device 13, when the water pump 5 and the air pump 6 are turned on, the water pressurized by the water pump 5 and the gas pressurized by the air pump 6 are delivered to the preliminary mixing device 13, mixed in the preliminary mixing device 13, and then delivered to the gas-liquid mixer 1 by the preliminary mixing device 13. And this embodiment is through the negative pressure adsorption performance that above-mentioned preliminary mixing device 13 itself had, when water pump 5 carried water to preliminary mixing device 13, preliminary mixing device 13 can produce the negative pressure to adsorb the gas that air pump 6 carried to it fast through this negative pressure to in, and with the water preliminary mixing that water pump 5 carried, carry the water and the gas of preliminary mixing to gas-liquid mixer 1 in afterwards again.
In this embodiment, an electrically controlled stop valve 10 is disposed between the first check valve 4 and the water pump 5, the electrically controlled stop valve 10 is connected to the controller, and the on/off of the water inlet pipeline 2 can be controlled by opening and closing the electrically controlled stop valve 10.
The controller of this embodiment is connected to a drain button (not shown in the figure), and specifically, a control panel (not shown in the figure) connected to the controller may be disposed on the micro-bubble water generating device, the drain button is disposed on the control panel, when a user presses the drain button, the control panel sends a signal to the controller, and the controller controls the micro-bubble water generating device to enter a drain state. When the micro-bubble water outlet effect is not obvious or the micro-bubble water outlet effect is not used for a long time, the water in the gas-liquid mixer 1 needs to be discharged, at the moment, a user opens the drain valve 12 and presses the drain button, the controller controls the electric control stop valve 10 to be closed, the water inlet pipeline 2 is disconnected, and the water in the gas-liquid mixer 1 is discharged out of the drain valve 12 through the pressure in the gas-liquid mixer 1. Through the mode, water in the gas-liquid mixer 1 can be discharged quickly, potential safety hazards to users cannot be caused, and personal safety of the users is guaranteed.
In this embodiment, a liquid level detection unit 8 is disposed in the gas-liquid mixer 1, and the liquid level detection unit 8 detects at least two liquid level detection points from high to low, for example: the embodiment can detect that two liquid level detection points exist. Specifically, the liquid level detection unit 8 includes a first detection probe 81 and a second detection probe 82, which are disposed from high to low, and the two detection probes respectively correspond to two liquid level detection points for detecting whether the liquid in the gas-liquid mixer 1 reaches the liquid level detection points.
The liquid level detecting unit 8 may also detect three liquid level detecting points, and at this time, the liquid level detecting unit 8 includes a first detecting probe 81, a second detecting probe 82, and a third detecting probe 83, which are disposed from high to low, and the three detecting probes respectively correspond to the three liquid level detecting points.
Because the water pump needs to be closed after the internal pressure of the existing gas-liquid mixer reaches a set value, and then in the use process, the drain valve of the gas-liquid mixer is frequently opened, so that the water pump needs to be started when the internal pressure of the gas-liquid mixer is lower than the set value, the drain valve is frequently opened and closed in the use process, the water pump is frequently started, and the service life of the water pump is influenced due to frequent starting. And under the highly compressed condition in water route, start the water pump and can lead to its stifled commentaries on classics, cause the water pump motor to become hot, seriously influence the life of water pump.
For the above reasons, the present embodiment has the third check valve 9 connected in parallel to both sides of the water pump 5 in the direction opposite to the water inlet direction (i.e., the direction of conduction with the first check valve 4), and the opening pressure of the third check 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 check valve 9, the third check valve 9 is conducted, and at the moment, the water flowing out after being pressurized by the water pump 5 flows to the inlet of the water pump 5 from the third check valve 9 and continues to be circulated by the water pump 5 without entering the gas-liquid mixer 1, so that the over-high pressure of the gas-liquid mixer 1 is avoided. And the third check valve 9 can reduce the opening and closing frequency of the water pump 5, and the service life of the water pump 5 can be prolonged.
In this embodiment, a pressure release valve 11 is further provided at the upper end of the gas-liquid mixer 1, when the first detection probe 81 of the liquid level detection unit 8 fails or the controller of the microbubble water generating apparatus fails, the water pump 5 cannot be closed or cannot be closed at this time, and through the pressure release valve 11, if the pressure in the gas-liquid mixer 1 reaches the pressure release pressure value of the pressure release valve 11, the pressure can be released by the pressure release valve 11, so as to ensure the safety of the gas-liquid mixer 1.
When the water in the gas-liquid mixer 1 needs to be discharged, a user opens the water discharge valve 12 and presses the water discharge key, the controller controls the electric control stop valve 10 to be closed to disconnect the water inlet pipeline 2, and the water in the gas-liquid mixer 1 can be discharged through the water discharge valve 12 due to certain pressure in the gas-liquid mixer 1.
By the drainage method, water can be drained through the pressure of the gas-liquid mixer 1, so that the drainage step is simplified, and potential safety hazards to users can be avoided.
In the embodiment, further, when water is not drained, that is, when micro bubble water needs to be generated, water may be delivered into the gas-liquid mixer 1 through the water pump 5, and gas may be delivered into the gas-liquid mixer 1 through the air pump 6, and the water and the gas maintaining a certain pressure in the gas-liquid mixer 1 are mixed to form the micro bubble water. And the testing probe of accessible liquid level detection unit 8 detects the liquid level in the gas-liquid mixer 1, when the liquid level in the gas-liquid mixer 1 is less than the second setting value that second testing probe 82 corresponds, second testing probe 82 feedback signal gives the controller, control water pump 5 and air pump 6 start respectively to preliminary mixing arrangement 13 in intaking and admitting air, the water that water pump 5 carried and the gas that the air pump 6 carried can carry out preliminary mixing under preliminary mixing arrangement 13's effect, and water and gas after the preliminary mixing flow to in the gas-liquid mixer 1 through preliminary mixing arrangement 13, and form little bubble water in gas-liquid mixer 1. The operating time T2 of the water pump 5 is recorded when the water pump 5 is started. With the continuous operation of the water pump 5 and the air pump 6, the liquid level in the gas-liquid mixer 1 reaches the second set value corresponding to the second detection probe 82.
When the liquid level reaches a second set value corresponding to the second detection probe 82, the second detection probe 82 feeds back a signal to the controller, the controller judges whether the operation time T2 of the water pump 5 is greater than or equal to a set water inlet time T3, if the operation time T2 of the water pump 5 is greater than or equal to the set water inlet time T3, it indicates that the pressure in the gas-liquid mixer 1 reaches the required pressure, and at this time, the controller closes the water pump 5 and the air pump 6.
Further, when the detection probes of the liquid level detection unit 8 of this embodiment are three, the liquid level reaches the second set value corresponding to the second detection probe 82, and the operation time T2 is greater than or equal to the set water inlet time T3, after the water pump 5 and the air pump 6 are turned off, when the user uses micro bubble water, the liquid level will fall between the third detection probe 83 and the second detection probe 82, at this time, the water pump 5 will not be turned on, until the liquid level falls to the first set value corresponding to the third detection probe 83 and below, the water pump 5 and the air pump 6 are controlled to feed water and intake air into the preliminary mixing device 13, and flow into the gas-liquid mixer 1 through the preliminary mixing device 13, and the above process is repeated until the liquid level reaches the second set value corresponding to the second detection probe 82.
If the operation time T2 is less than the set water inlet time T3, at this time, although 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, at this time, the controller controls the water pump 5 to continue to feed water until the set water inlet time T3, and the air pump 6 is turned off;
in the process that the water pump 5 continues to feed water until the set water feeding time T3, when the pressure in the gas-liquid mixer 1 is smaller than the opening pressure of the third check valve 9, the water pump 5 continues to feed water into the gas-liquid mixer 1. When the pressure in the gas-liquid mixer 1 is higher than the opening pressure of the third check valve 9, the water output by the water pump 5 flows to the inlet of the water pump 5 through the third check valve 9 and circularly flows, at this time, the water pump 5 does not feed water into the gas-liquid mixer 1, and the pressure in the gas-liquid mixer 1 is kept constant. The water circulation of the water pump 5 flows, the opening and closing frequency of the water pump 5 can be reduced, and the service life of the water pump 5 can be prolonged.
In this embodiment, when the third check valve 9 fails, if the liquid level in the gas-liquid mixer 1 reaches a 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 sends an alarm through the display or the buzzer, so as to prompt a user that the pressure in the gas-liquid mixer 1 is too high, and drainage needs to be performed in time, so as to prevent the pressure in the gas-liquid mixer 1 from being too high and affecting the safety performance of the gas-liquid mixer 1.
In this embodiment, when the controller that liquid level detection unit 8 became invalid and could not detect third setting value or little bubble water generation device became invalid, there was continuous intaking of water pump 5 this moment, and the pressure in the gas-liquid mixer 1 is bigger and bigger, and when the pressure in the gas-liquid mixer 1 reached the pressure release pressure value of relief valve 11, can carry out the pressure release through relief valve 11 to make the pressure in the gas-liquid mixer 1 no longer rise, avoid gas-liquid mixer 1 pressure too high to influence safe handling.
The second embodiment:
the present embodiment provides a micro-bubble water generating device and an automatic drainage method thereof, wherein the micro-bubble water generating device has substantially the same structure as the first embodiment, except that:
in this embodiment, when the user presses the drainage button, the microbubble water generating device enters a drainage state, and after the user opens the drainage valve 12, the controller controls the electrically controlled stop valve 10 to close, and starts the air pump 6 to intake air into the gas-liquid mixer 1, so that the pressure in the gas-liquid mixer 1 is increased, and then the water in the gas-liquid mixer 1 is rapidly discharged.
Further, as shown in fig. 2, a pressure detection unit 15 connected to a controller is disposed in the gas-liquid mixer 1 of the present embodiment, specifically, the pressure detection unit 15 may be a pressure sensor, when a user presses a drain button and forgets to open the drain valve 12, pressure in the gas-liquid mixer 1 may become high due to continuous air intake of the air pump 6, and when the pressure detection unit 15 detects that the pressure in the gas-liquid mixer 1 exceeds a set value, the controller closes the air pump 6, and gives an alarm in a sound or screen display manner to prompt the user to open the drain valve 12.
The rest of the structure of the microbubble water generating device in this embodiment is the same as that in the first embodiment, and is not described again. Through the mode that the air pump 6 admits air into the gas-liquid mixer 1, the water in the gas-liquid mixer 1 can be discharged more quickly, so that a user does not need to wait for a long time, and the personal safety of the user is also ensured.
