[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0026] In the following description, the terms "first, second, etc." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0027] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0028] The embodiment of the present invention provides a degassed water treatment system, which can be applied to ultrasonic beauty equipment, ultrasonic medical equipment, or other equipment that requires degassed water, such as sewage treatment equipment, drinking water treatment equipment, power plant cooling water treatment equipment, etc. It should be noted that the application scenario type of the embodiment of the present invention does not limit the structure of the degassed water treatment system of the embodiment of the present invention.

[0029] like Figure 1 and Figure 2 As shown, the deaerated water treatment system includes a deaerated water device 1, a vacuum deaerator 2, a control system 3 and a water delivery member 4. The deaerated water device 1 has a water storage chamber 111, a water inlet channel 112, a water outlet channel 113 and an air extraction channel 114. The water to be degassed is stored in the water storage chamber 111, or the water after degassed is temporarily stored in the water storage chamber 111. The water inlet channel 112, the water outlet channel 113 and the air extraction channel 114 are spaced apart from each other and are not connected to each other, but the water inlet channel 112, the water outlet channel 113 and the air extraction channel 114 are all connected to the water storage chamber 111. The vacuum deaerator 2 is connected to the air extraction channel 114 and can perform vacuum degassing on the water flowing into the water storage chamber 111. The vacuum deaerator 2 extracts the air in the water storage chamber 111 through the air extraction channel 114, so that the water storage chamber 111 forms a vacuum environment. It can be understood that according to the Clausius-Clapeyron equation, the equation describes the relationship between the boiling point and pressure of a liquid. Specifically, the saturated vapor pressure of a liquid increases as the temperature increases, and conversely, the saturated vapor pressure of a liquid decreases as the pressure decreases. Therefore, after the vacuum degassing device 2 evacuates the water storage chamber 111, the pressure in the water storage chamber 111 decreases, and the boiling point of water decreases. When the pressure drops low enough, the water will boil even at room temperature. The gas molecules in the water flow overflow to form "degassing"; after the water flow input into the water storage chamber 111 from the water inlet channel 112 contacts the vacuum environment, it is vacuum degassed to form "degassed water", and the degassed water flows out of the water storage chamber 111 through the water outlet channel 113.

[0030] like Figure 3 As shown, the deaerated water device 1 and the vacuum deaerator 2 are both electrically connected to the control system 3, and the control system 3 is used to control the working states of the deaerated water device 1 and the vacuum deaerator 2. For example, the control system 3 can control the start and stop of the deaerated water device 1 and / or the vacuum deaerator 2, control the water inlet flow rate and / or the water outlet flow rate of the deaerated water device 1, and control the suction power of the vacuum deaerator 2, so as to control the oxygen content, preparation volume, preparation time and other parameters in the deaerated water, and thus obtain deaerated water that meets the requirements.

[0031] like Figure 2As shown, in some embodiments, the water conveying member 4 is arranged in the water storage chamber 111, and the water inlet channel 112 is located above the water outlet channel 113. In the height direction of the water storage chamber 111, the water conveying member 4 can be located between the water inlet channel 112 and the water outlet channel 113, or part of the water conveying member 4 can be located above the water inlet channel 112, and / or part of the water conveying member 4 can be located below the water outlet channel 113. The water conveying member 4 can rely on gravity to convey water flow in the direction from the water inlet channel 112 to the water outlet channel 113. Of course, the water conveying member 4 can also convey water flow in the direction from the water outlet channel 113 to the water inlet channel 112 through components such as a water pump. The present application does not limit the direction in which the water conveying member 4 conveys water flow, as long as the water conveying member 4 can convey water to be vacuum degassed.

[0032] like Figure 2 As shown, after the water to be vacuum degassed enters the water storage chamber 111, it is transported through the water conveying member 4. One end of the water conveying member 4 can be directly connected to the water inlet channel 112 or separated from the water outlet channel 113; the other end of the water conveying member 4 can be directly connected to the water outlet channel 113 or separated from the water outlet channel 113, as long as the water conveying member 4 can transport the water to be vacuum degassed. The water conveying member 4 can make the water flow in the water storage chamber 111 circulate in the water storage chamber 111. The inner cavity of the water conveying member 4 is connected to the water storage chamber 111. The water flow in the inner cavity of the water conveying member 4 can directly contact the vacuum environment, so that the water flow can be degassed during the circulation process. The water flow to be vacuum degassed keeps circulating on the water conveying member 4, and the molecular movement speed in the water flow becomes larger, which is convenient for gas molecules to overflow and achieve degassing. Compared with centrally setting the water flow to be vacuum degassed in one area, the water flow input from the water inlet channel 112 in the present application is dispersed in the inner cavity of the water conveying member 4. In the flow path formed by the water conveying member 4, the water flow flowing to any position of the water conveying member 4 can contact the vacuum environment. The setting of the water conveying member 4 increases the contact area and time between the water flow and the vacuum environment, which is convenient for quickly preparing degassed water and improving the degassing efficiency. In addition, the water conveying member 4 allows the water flow in the water storage chamber 111 to circulate in the water storage chamber 111, extending the water flow path. The water flow can contact the vacuum environment for a longer time in a longer path, so that the water flow can contact the vacuum environment more fully, which is conducive to improving the degassing efficiency and degassing quality.

[0033] Specifically, the water conveying member 4 may be a waterwheel-shaped member that curves around the horizontal direction. In some possible implementations, the water flow input from the water inlet channel 112 may drive the water conveying member 4 to rotate around the axis in the horizontal direction to stir the water at the bottom of the water storage chamber 111 to keep the water circulating. The present application does not limit the shape of the water conveying member 4. Regardless of how the water conveying member 4 is arranged, the water on the water conveying member 4 can contact the vacuum environment during the flow process, and can achieve vacuum degassing during the flow process.

[0034] The degassed water treatment system provided by the embodiment of the present invention comprises a degassed water device 1, a vacuum degassed device 2, a control system 3 and a water conveying member 4. The degassed water device 1 comprises a water storage chamber 111 and a water inlet channel 112, a water outlet channel 113 and an air extraction channel 114 connected to the water storage chamber 111, and the air extraction channel 114, the water inlet channel 112 and the water outlet channel 113 are spaced apart from each other. The vacuum degassed device 2 is connected to the air extraction channel 114, and performs vacuum degassing treatment on the water flowing into the water storage chamber 111. The degassed water device 1 and the vacuum degassed device 2 are both electrically connected to the control system 3, and the control system 3 is used to control the working states of the degassed water device 1 and the vacuum degassed device 2. The water conveying member 4 is arranged in the water storage chamber 111, and conveys water to be vacuum degassed. After the water to be vacuum degassed is input into the water inlet channel 112, the water conveying member 4 causes the water flow in the water storage chamber 111 to circulate in the water storage chamber 111. The inner cavity of the water conveying member 4 is connected to the water storage chamber 111, and the water flow in the water conveying member 4 contacts the vacuum environment in the water storage chamber 111 to achieve degassing. In this way, the water conveying member 4 circulates the water flow to be vacuum degassed, so that the water flow contacts the vacuum environment during the circulation process, increasing the contact area between the water flow and the vacuum environment, improving the degassing efficiency, and facilitating the rapid preparation of degassed water with low oxygen content. In addition, the water conveying member 4 is arranged in the water storage chamber 111, making full use of the space in the water storage chamber 111, not occupying additional space, and having a high space utilization rate, which is conducive to reducing the overall volume of the equipment.

[0035] In some embodiments, Figure 2 As shown, at least part of the water conveying member 4 is bent, and a multi-layer stacked water conveying space is formed in the height direction of the water storage chamber 111 to increase the contact area between the water flow and the vacuum environment, that is, the water conveying member 4 has at least two layers of water conveying space, so that the water flow is stacked in at least two layers on the water conveying member 4. The at least part of the water conveying member 4 is bent, which means that the water conveying member 4 can convey the water flow in opposite directions, so that the water flow flows in a winding manner.

[0036] Specifically, Figure 2 and Figure 3 In the first embodiment shown, the water conveying member 4 may be a spiral member spirally arranged around the axis of the water storage chamber 111 in the height direction, wherein the diameter of each layer of water conveying space formed by the water conveying member 4 is the same, so that the water flows in a spiral shape.

[0037] like Figure 4 In the second embodiment shown, the water conveying member 4 may also be a laminated member formed by repeatedly bending along the height direction of the water storage chamber 111, and each layer of water conveying space formed by the water conveying member 4 is arranged in parallel. In this case, each layer of water conveying space formed by the water conveying member 4 may extend horizontally; of course, in order to make the water flow smoothly, the downstream side of each layer of conveying space formed by the water conveying member 4 may also be inclined downward.

[0038] like Figure 5 In the third embodiment shown in the figure, the water delivery member 4 can also be a spiral member arranged around the axis in the height direction of the water storage chamber 111, wherein the diameter of each layer of water delivery space formed by the water delivery member 4 is different. Figure 5 In the top view shown, the diameter of the water delivery space formed by the water delivery member 4 increases from top to bottom; of course, in other embodiments, the diameter of the water delivery space formed by the water delivery member 4 may also decrease from top to bottom. It can be understood that in the third embodiment, in order to make the water flow smoothly, the downstream side of each layer of the delivery space formed by the water delivery member 4 may also be inclined downward.

[0039] like Figure 6 In the fourth embodiment shown, the water conveying member 4 can also be a fin-shaped member that is stacked parallel to each other in the height direction of the water storage chamber 111 and is interconnected. Each layer of water conveying space formed by the water conveying member 4 is arranged around the axis of the water storage chamber 111 in the height direction, and each water conveying space is parallel to each other and is interconnected. It can be understood that in the fourth embodiment, in order to make the water flow smoothly, the downstream side of each layer of conveying space formed by the water conveying member 4 can also be tilted downward.

[0040] Regardless of which of the above-mentioned embodiments the water conveying member 4 is arranged, the water conveying member 4 is partially bent, and repeatedly conveys water in different directions in the water storage chamber 111, so that the water flow "circulates"; the water conveying member 4 forms a bent water flow path, so that the water flow flows in a winding manner. The water conveying member 4 relatively fully extends the water flow path within a limited space, so that the water flow to be vacuum degassed can contact the vacuum environment in a longer path, further increasing the area and time of contact between the water flow and the vacuum environment, which is beneficial to improving the degassing efficiency and quality. In addition, the water conveying member 4 fully utilizes the water storage space of the water storage chamber 111 in the height direction, which is beneficial to reducing the space of the water storage chamber 111 in the horizontal direction, thereby reducing the floor space of the degassed water device 1, making it feasible to reduce the overall volume of the degassed water treatment system.

[0041] In some embodiments, Figure 2As shown, the water conveying member 4 is configured as a water trough structure that opens upwards, and is spirally arranged along the axis of the water storage chamber 111 in the height direction. That is to say, the water conveying member 4 is a spiral member that is spirally arranged around the axis of the water storage chamber 111 in the height direction, and the cross-sectional shape of the flow channel of the water conveying member 4 is roughly in the shape of a trough that opens upwards. It can be simply understood that the water conveying member 4 has an open profile, and the cavity wall of any part of the water conveying member 4 is open upwards. Compared with the embodiment in which the water conveying member 4 has a closed profile and a through hole is opened to connect the inner cavity of the water conveying member 4 and the water storage chamber 111, in the present application, the inner cavity of the water conveying member 4 is connected to the water storage chamber 111 through the upward opening, and the channel connecting the inner cavity of the water conveying member 4 and the water storage chamber 111 is larger, so the area where the water flow in the water conveying member 4 contacts the vacuum environment is larger, which facilitates the water flow in the water conveying member 4 to contact the vacuum environment, further increasing the degassing efficiency. In addition, it is also convenient for gas molecules in the water flow arranged in the water delivery member 4 to be discharged smoothly, reducing the possibility of explosion or damage of the water delivery member 4 due to rapid expansion of gas molecules, and extending the service life of the water delivery member 4. Moreover, the spirally arranged water delivery member 4 can also extend the water flow delivery time, thereby increasing the water flow degassing time, which is conducive to more fully degassing the water flow and improving the degassing effect.

[0042] In some possible implementation schemes, a collision protrusion may be provided on the inner surface of the water conveying member 4 or a rotatable water baffle may be provided inside the water conveying member 4, so that the water flow collides with the collision protrusion or the water baffle during the flow, thereby reducing the water flow velocity, thereby further disturbing the water flow, forming turbulence, increasing the cavitation effect, and allowing the gas molecules to be discharged quickly and more fully from the water flow, thereby further increasing the degassing efficiency.

[0043] In some embodiments, Figure 2 and Figure 3As shown, the water inlet channel 112 is arranged above the water outlet channel 113, and the air extraction channel 114 is arranged above the water inlet channel 112. That is to say, the water flows from top to bottom along the direction from the water inlet channel 112 to the water outlet channel 113, and the gas molecules flow from bottom to top along the direction from the water inlet channel 112 to the air extraction channel 114. The flow direction of the water flow path is opposite to that of the air flow path, which reduces the possibility of the overflowed gas molecules re-entering the degassed water. In addition, the opposite ends of the water conveying member 4 are respectively the water inlet end 41 and the water outlet end 42. The water inlet end 41 (upper end) is connected to the water inlet channel 112, and the water outlet end 42 (lower end) is connected to the water outlet channel 113. That is to say, the water conveying member 4 can directly guide the water flow from the water inlet channel 112 to the water outlet channel 113, so that the degassed water device 1 can supply degassed water to other equipment in a more timely manner. Compared with setting the other end of the water conveying member 4 at other positions, for example, setting the other end of the water conveying member 4 above the water outlet channel 113, in the present application, the other end of the water conveying member 4 is connected to the water outlet channel 113, and the water flow path formed by the water conveying member 4 is longer, which is convenient for the water flow to more fully contact the vacuum environment, so as to more fully perform degassing treatment.

[0044] Continue to refer to Figure 2 and Figure 3 As shown, the water inlet end 41 and the water outlet end 42 are both arranged in the water storage chamber 111, and are both located in the vacuum environment of the water storage chamber 111. That is to say, the water inlet channel 112 and the water outlet channel 113 are both partially extended into the water storage chamber 111, the water inlet end 41 and the water outlet end 42 are both located in the water storage chamber 111, and the water trough structure on the water conveying member 4 extends from the water inlet end 41 to the water outlet end 42, and is both located in the water storage chamber 111, so that the water flow on the water conveying member 4 is fully exposed to the vacuum environment, thereby increasing the degassing efficiency. The water inlet end 41 and the water outlet end 42 of the water conveying member 4 are not directly in contact with the external environment, but are arranged in the water storage chamber 111, the water inlet end 41 is connected to the external environment via the water inlet channel 112, and the water outlet end 42 is connected to the external environment via the water outlet channel 113. Such an arrangement makes the pressure at both ends of the water conveying member 4 relatively balanced, reducing the possibility of the water conveying member 4 absorbing or spraying water due to uneven pressure at both ends.

[0045] It should be noted that the embodiment shown in the schematic diagram of the present application is only an illustrative implementation. In other embodiments, the water inlet end 41 of the water conveying member 4 may be separated from the water inlet channel 112 and the water outlet channel 113, and the water outlet end 42 of the water conveying member 4 may be connected to the water inlet channel 112. In this implementation, the water conveying member 4 may be provided with a water pump inside or outside the water storage chamber 111, the water pump is connected to the water outlet channel 113, and pumps the water flow of the water outlet channel 113 from bottom to top into the water inlet end 41 of the water conveying member 4. In some possible implementations, the water inlet end 41 and the water outlet end 42 of the water conveying member 4 may not be connected to the water inlet channel 112 and the water outlet channel 113. In this implementation, the water inlet end 41 is located above the water outlet end 42, and a water pump may be provided inside the water storage chamber 111 to pump the water flow at the bottom of the water storage chamber 111 into the water inlet end 41, and then the water flow automatically flows to the water outlet end 42 under the action of gravity. No matter how the water inlet 41 and the water outlet 42 of the water conveying member 4 are arranged, as long as the water inlet 41 and the water outlet 42 of the water conveying member 4 are both located in the water storage chamber 111 , the water conveying member 4 can convey the water to be vacuum degassed in the water storage chamber 111 .

[0046] In some embodiments, Figure 2 and Figure 3 As shown, the deaerated water device 1 includes a water tank 11, a water inlet valve 12 and a drainage pump 13. The inner cavity of the water tank 11 forms a water storage chamber 111. The water tank 11 is provided with the above-mentioned water inlet channel 112, water outlet channel 113 and air extraction channel 114. The water inlet valve 12 is installed in the water inlet channel 112, and the water inlet valve 12 is electrically connected to the control system 3. The control system 3 controls the water flow rate, inflow time and other parameters input from the water inlet channel 112 by controlling the water inlet valve 12, and can open and close the water inlet channel 112. The drainage pump 13 is at least connected to the water outlet channel 113, and can be switched to output the deaerated water. The drainage pump 13 is also electrically connected to the control system 3. The control system 3 can measure and feedback the oxygen content of the deaerated water in the drainage pump 13. When the oxygen content of the deaerated water in the drainage pump 13 reaches a preset value, the drainage pump 13 outputs the deaerated water. The control system 3 is used to monitor the oxygen content of the degassed water in the drainage pump 13 in real time and feed the data back to the user, which helps the user to intuitively judge whether the oxygen content in the degassed water reaches the preset value. The user can also selectively export degassed water with a set oxygen content according to the data and needs, so as to meet the user's personalized needs.

[0047] In some embodiments, Figure 3As shown, the drainage pump 13 is provided with a water inlet pipeline 131, a first water outlet pipeline 132 and a second water outlet pipeline 133. The water inlet pipeline 131 is connected to the water outlet channel 113. The first water outlet pipeline 132 can be switched to output degassed water, and the second water outlet pipeline 133 is connected to the water inlet channel 112. The control system 3 sends a first instruction and a second instruction to the drainage pump 13. Under the first instruction, the oxygen content of the degassed water in the drainage pump 13 does not reach the preset value, the first water outlet pipeline 132 is closed, and the second water outlet pipeline 133 is opened. The degassed water whose oxygen content does not reach the preset value is guided to the water inlet channel 112 via the second water outlet pipeline 133, and is again spirally transported via the water conveying member 4 to contact the vacuum environment again for secondary degassing. Under the second instruction, the oxygen content of the degassed water in the drainage pump 13 reaches a preset value, the first water outlet pipe 132 is opened, and the second water outlet pipe 133 is closed. The degassed water with an oxygen content reaching the preset value is discharged through the first water outlet pipe 132 and directed to other equipment. After the second water outlet pipe 133 is connected to the water inlet channel 112, a recyclable water path is formed, so that the water flow is repeatedly degassed, and degassed water with a lower oxygen content can be obtained, thereby improving the quality of the degassed water. In addition, the entire flow path is closed-loop controlled by the control system 3, which can be monitored and regulated in real time, with a high degree of intelligence. There is no need to manually adjust the drainage pump 13 and the water inlet valve 12, and the operation is simple.

[0048] In some embodiments, Figure 2 and Figure 3 As shown, the vacuum degassing device 2 includes a water vapor separation box 21 and a vacuum pump 22 which are interconnected. Figure 3 , a water storage area 211 and a drying area 212 are formed in the water vapor separation box 21, and the water storage area 211 is located below the drying area 212 and is connected to the air extraction channel 114. It can be understood that the gas extracted through the air extraction channel 114 is attached with water molecules and can be regarded as water vapor or humid air. The vacuum pump 22 is connected to the drying area 212, and the vacuum pump 22 is electrically connected to the control system 3, and the air in the water tank 11 is pumped into the water storage area 211 in the water vapor separation box 21 to separate the gas molecules and water molecules in the humid air, so that the water molecules are retained in the water storage area 211, and the gas molecules enter the drying area 212 and are pumped into the vacuum pump 22. The water storage area 211 is below the drying area 212, and the water molecules are stored in the water storage area 211 under the action of gravity to reduce the possibility of water molecules in the water storage area 211 entering the drying area 212, thereby reducing the possibility of water vapor entering the vacuum pump 22.

[0049] Specifically, a water accumulation membrane can be used to separate the water storage area 211 and the drying area 212. The water accumulation membrane is provided with through holes through which only gas molecules can pass, so that the gas molecules in the moisture are separated from the water molecules. The water molecules are stored in the water storage area 211, and only the gas molecules enter the drying area 212 to form dry air, thereby reducing the risk of humid air entering the vacuum pump 22 and then damaging the vacuum pump 22, which is beneficial to extending the service life of the vacuum pump 22.

[0050] In some embodiments, Figure 3 As shown, a water vapor adsorbent 2111 for adsorbing water vapor is provided in the water storage area 211. Specifically, the materials of the water vapor adsorbent 2111 include but are not limited to hygroscopic salt composite adsorbents, MOFs (metal organic framework) materials, graphene, etc. In this way, while adsorbing water molecules and separating gas molecules, the chloride ions in the adsorbed gas molecules can also be reduced to further reduce the possibility of damage to the vacuum pump 22 and extend the service life of the vacuum pump 22. In addition, compared with the implementation of setting a water accumulation membrane, in the present application, the water vapor adsorbent 2111 is filled in the water storage area 211. In the process of gas entering the drying area 212 from the water storage area 211, the water vapor can continuously contact the water vapor adsorbent 2111 in the height space of the water storage area 211, which is convenient for the water molecules in the humid water vapor to be more fully separated from the gas molecules, and the water vapor separation efficiency is high.

[0051] In some embodiments, Figure 2 and Figure 3 As shown, the degassing water treatment system also includes a cabinet 5, and a mounting cavity 51 is formed inside the cabinet 5. The degassing water device 1 and the vacuum degassing device 2 are both installed in the mounting cavity 51. This arrangement makes the degassing water treatment system provided by the present application present a modular frame structure, which is convenient for moving the degassing water treatment system and further facilitating the docking of the degassing water treatment system with other equipment. The control system 3 includes a circuit control box 31 and a host computer 32. The circuit control box 31 is arranged on the cabinet 5 (refer to Figure 2 ), and the circuit control box 31 is electrically connected to the host computer 32 (refer to Figure 3 ). With this arrangement, the upper computer 32 can be used to program software into the circuit control box 31, so as to use the computer software to control and intelligently monitor the deaerated water treatment system. The deaerated water preparation process and preparation parameters can be displayed on the computer software, making the deaerated water preparation process and preparation parameters visible, with a high degree of intelligence, and can adjust and monitor various parameters of the deaerated water in real time to meet the personalized needs of users.

[0052] In some embodiments, Figure 2As shown, the cabinet 5 is provided with a water level gauge 52, a first detection tube 53 and a second detection tube 54. The water level gauge 52 is arranged on the outside of the cabinet 5 and is used to monitor the water level in the water tank 11. The first detection tube 53 and the second detection tube 54 are both connected to the water level gauge 52 and communicate with the water storage chamber 111, that is, the water level gauge 52 is communicated with the water storage chamber 111, so that the pressure of the internal cavity of the water level gauge 52 is consistent with the water storage chamber 111, and the liquid level in the internal cavity of the water level gauge 52 represents the liquid level in the water tank 11. The first detection tube 53 and the second detection tube 54 are connected to the same side of the water tank 11 and are arranged at intervals up and down. For example, the first detection tube 53 can be located above the second detection tube 54. The water level gauge 52 is connected between the first detection tube 53 and the second detection tube 54. It can be understood that the water level gauge 52 used in this application is a magnetic float type liquid level gauge. The liquid level in the water tank 11 is displayed on the flap indicator, and the reading is intuitive and has high accuracy. The magnetic float type liquid level gauge can be equipped with a magnetic switch as an electrical contact signal output, or a liquid level transmitter can be configured for long-distance liquid level signal transmission and liquid level control, thereby improving the intelligent control level of the degassed water treatment system and making the liquid level in the water tank 11 controllable.

[0053] In some possible implementations, the inner wall of the water tank 11 is coated with sound-absorbing cotton, and / or the outer wall of the vacuum pump 22 is coated with sound-absorbing cotton to reduce the working noise of the vacuum pump 22 and also reduce the noise generated by boiling water during vacuum degassing. In addition, the vacuum pump 22 can also be equipped with a muffler to further reduce the noise of the vacuum pump 22 when it is working.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
