Description

Technical Field

[0001] This invention belongs to the technical field of negative oxygen ion devices, specifically relating to a gas-pumping negative oxygen ion generator. Background Technology

[0002] Using compressed air (or oxygen) to impact water and an air-impact plate can produce negative oxygen ions with properties and therapeutic effects equivalent to those produced in the natural environment. An air-impact negative oxygen ion generator described in application number 202211363312.X, although producing a much higher concentration of negative oxygen ions than the air-induced negative oxygen ion generator described in authorization announcement number CN110620333B, still requires the negative oxygen ion air output from the gain tube to first diffuse within the inner cavity of the cup before being output from the outlet. The water inside the cup and lid absorbs and neutralizes some of the negative oxygen ions, reducing the concentration. Therefore, the concentration of negative oxygen ions produced still needs to be improved. Summary of the Invention

[0003] This invention aims to provide an air-impact negative ion generator that solves any of the aforementioned problems. Specifically, this invention provides an air-impact negative ion generator, including a cup body, a cup lid, and a negative ion generating device. The negative ion generating device is disposed within the inner cavity of the cup body. The negative ion generating device includes a generating device body, an air-impact plate, an air inlet pipe, and a gain pipe. The generating device body and the air-impact plate form an air-impact chamber. The lower end of the gain pipe is connected to the air-impact chamber, and the upper end is connected to the air outlet of the negative ion generator through a water removal structure. One end of the air inlet pipe is connected to an air source, and the other end is connected to the air-impact hole. The air-impact plate is positioned in front of the air outlet direction of the air-impact hole. The water removal structure includes an airflow accommodating space, an inlet, an outlet, and a drain outlet connected to the airflow accommodating space. The inlet is connected to the gain pipe, the outlet is connected to the air outlet, and the drain outlet is located at the bottom of the accommodating space. Furthermore, the inlet and the outlet are staggered.

[0004] In one embodiment, the gain tube is sleeved on the outside of the intake pipe, or the gain tube is arranged side by side with the intake pipe, or the gain tube is arranged opposite to the intake pipe.

[0005] In one embodiment, the gain tube is spiral-shaped.

[0006] In one embodiment, both the air inlet and the air outlet are located on the cup lid; or,

[0007] The air inlet pipe is located on the cup body, and the air outlet is located on the cup lid.

[0008] In one embodiment, the negative oxygen ion generator body is a container with an open bottom and a semi-closed top, and the air impact plate is fixed to the open section of the generator body.

[0009] In one embodiment, the air-striking plate is provided with an air-striking plate water inlet at a position avoiding the air-striking hole, for introducing water from the cup into the air-striking chamber.

[0010] In one embodiment, a water suction hole communicating with the air impact hole is formed on the side of the air impact hole, and a water inlet hole is formed on the main body of the generating device. The water suction hole is connected to the water inlet hole through a water inlet pipe.

[0011] In one embodiment, the generator body of the negative oxygen ion generator is a box structure, the box wall is provided with an installation interface for installing the air inlet pipe, and the box wall opposite to the air inlet pipe is provided with an air impact hole; the air impact plate is fixedly connected to the box structure, so that the air impact chamber is formed between the air impact plate and the generator body.

[0012] In one embodiment, the generator body of the negative oxygen ion generator is disposed at the bottom of the cup body, and the air inlet pipe passes through the bottom wall of the cup body and communicates with the external air passage.

[0013] In one embodiment, the dewatering mechanism includes a first upper component and a first lower component, wherein the first upper component includes a first annular wall that is fixedly connected to or integrally formed with the cup lid, and the first upper component and the cup lid form a cavity; the first lower component includes a base plate and a second annular wall that is vertically disposed on the edge of the base plate, the second annular wall surrounding the first annular wall; the inlet and the drain outlet are disposed on the base plate, and the inlet is formed between the first annular wall and the second annular wall; the gain tube passes through the inlet and is sealed to the side wall of the inlet.

[0014] In one embodiment, the water removal mechanism is a box-shaped structure, including a box-shaped body and an inlet, an outlet and a drain outlet disposed on the box-shaped body. The box-shaped body includes a top plate, a bottom plate and a side plate. The inlet is disposed on the side plate, the outlet is disposed on the top plate and the drain outlet is disposed on the bottom plate.

[0015] The solution of the present invention has the following effects:

[0016] The negative oxygen ions in the air strongly rub against and impact the inner wall of the gain tube. Because the inlet and outlet of the dehydration mechanism are staggered (not directly opposite each other, or there are obstructions in the flow path, or the airflow direction is inconsistent), the airflow flows fully within the dehydration mechanism's space and rubs against and impacts the inner wall of the mechanism. Based on the principle of triboelectric charging and the Lenard effect, the concentration of negative oxygen ions in the air is significantly increased after passing through the gain tube and the dehydration mechanism. Furthermore, the dehydration mechanism is a semi-enclosed structure; that is, apart from the inlet, outlet, and drain, there are no other openings to the outside. This prevents the negative oxygen ions from diffusing into the inner cavity of the cup and allows them to be directly discharged from the outlet through the small dehydration mechanism with minimal loss. After dehydration, the final product is negative oxygen ion air with a high concentration and moderate humidity.

[0017] Furthermore, it generates a high concentration of negative oxygen ions, reaching up to 50 million per cubic centimeter. 3 With the negative oxygen ion generator covering the water surface inside the cup, the water level has little effect on the concentration of negative oxygen ions, remaining below 10%. The generated negative oxygen ions are ozone-free, nitrogen oxide-free, and free from static electricity. The water surface inside the bottle remains still, resulting in minimal noise.

Detailed Implementation

[0029] To make the technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Some technical terms and expressions used herein have the same meaning as understood by those skilled in the art to which this application pertains.

[0030] like Figure 1-10As shown, an air-impact negative ion generator of the present invention includes a cup body 1, a cup lid 2, and a negative ion generating device 3. The negative ion generating device 3 is disposed in the inner cavity of the cup body 1. The negative ion generating device 3 includes a generating device body 301, an air-impact plate 302, an air inlet pipe 303, and a gain pipe 304. The generating device body 301 and the air-impact plate 302 form an air-impact chamber 305. The lower end of the gain pipe 304 is connected to the air-impact chamber 305, and the upper end is connected to the air outlet 202 of the negative ion generator through a water removal structure 4. One end of the air pipe 303 is connected to an air source, and the other end is connected to an air impact hole 306. The impact plate is positioned in front of the air outlet direction of the air impact hole 306. The water removal structure 4 includes an airflow receiving space. The water removal structure 4 includes an inlet 403, an outlet 402, and a drain 423 connected to the airflow receiving space. The inlet 403 is connected to the gain pipe 304, the outlet 402 is connected to the air outlet 202, and the drain 423 is located at the bottom of the space. Furthermore, the inlet 403 and the outlet 402 are staggered.

[0031] During operation, compressed air is input from the air source (or may be further processed through the air path), enters the air inlet pipe 303, and is ejected from the air impact hole 306, impacting the water and air impact plate 302 to form negative oxygen ion air. The negative oxygen ion air enters the water removal mechanism 4 along the gain pipe 304, removes some moisture, and is then discharged from the air outlet 202. Testing showed that using an air pump with a flow rate of 30 liters / minute and a pressure of 0.15 MPa, the negative oxygen ion concentration reached 40 million / cm³. 3 .

[0032] In this scheme, compressed air (or oxygen) is ejected at high speed from the air impact hole 306, impacting the water and the air impact plate 302, generating air with a certain concentration of negative oxygen ions with high humidity. The negative oxygen ion air enters the dehydration mechanism 4 along the gain tube 304. The negative oxygen ion air strongly rubs and impacts the inner wall of the gain tube 304. Furthermore, because the inlet 403 and outlet 402 of the dehydration mechanism 4 are staggered, i.e., not directly opposite each other, or there is an obstruction in the flow path, or the direction of airflow is inconsistent, the airflow will flow fully within the accommodating space of the dehydration mechanism 4 and rub against and impact the inner wall of the dehydration mechanism 4. According to the principle of triboelectricity and Lenard effect, the concentration of negative oxygen ion air is greatly increased after passing through the gain tube 304 and the dehydration mechanism 4. Furthermore, the dewatering mechanism 4 is a semi-enclosed structure, meaning that apart from the inlet 403, outlet 402, and drain 423, there are no other openings for communication with the outside. This prevents the negative ion air from diffusing into the inner cavity of the cup body 1, and it is directly discharged from the outlet 202 through the small-volume dewatering mechanism 4, resulting in minimal loss. After dewatering, the final product is negative ion air with a high concentration of negative ions and moderate humidity. In addition, the negative ion gas does not escape upwards from the water, reducing the noise generated by the bubbles in the water.

[0033] Water is placed inside the cup body 1, preferably purified water or distilled water, but tap water, mineral water, or water with dissolved medicine can also be used. The cup body 1 and the cup lid 2 are detachably and sealingly connected, and the connection methods include threaded connection, bolt connection, flange connection, and snap-fit ​​connection. To improve the sealing performance, a cup lid sealing ring 206 is provided at the connection between the cup body 1 and the cup lid 2.

[0034] In one embodiment, the gain tube 304 is sleeved on the outside of the air inlet pipe 303. The gap between the air inlet pipe 303 and the gain tube 304 forms a flow channel for the negative oxygen ion gas. Preferably, a connecting piece 3031 is provided between the gain tube 304 and the air inlet pipe 303 to more effectively fix the two together. Of course, the gain tube 304 can also be arranged side by side with the air inlet pipe 303. For example, both the gain tube 304 and the air inlet pipe 303 are connected to the generator body 301, or the gain tube 304 and the air inlet pipe 303 are arranged opposite to each other. For example, the gain tube 304 is connected to the gas cover 308, and the air inlet pipe 303 is connected to the generator body 301.

[0035] In one embodiment, the gain tube 304 is spiral-shaped. This design allows the air carrying negative oxygen ions to travel a greater distance within the spiral gain tube 304, resulting in a greater increase in negative oxygen ion concentration. The gain tube 304 is preferably made of a metal tube, a conductive plastic tube, or a plastic tube coated with a conductive layer, or at least its surface is conductive. Using a conductive material in the gain tube 304 significantly increases the negative oxygen ion concentration. In another embodiment, to save costs and reduce processing difficulty, non-conductive plastic tubes or ceramic tubes can also be used. For example, for ease of manufacturing, a plastic tube is used when the gain tube 304 is integrally formed with the generating device body 301. Experiments have shown that when the inner diameter of the gain tube 304 is 3–10 mm and the annular gap of the gain tube 304 is 0.5–4 mm, the negative oxygen ion concentration is significantly increased.

[0036] In one embodiment, both the air inlet pipe 303 and the air outlet 202 are disposed on the cup lid 2. For example, the air inlet pipe 303 is disposed in the center of the cup lid 2, and the air outlet 202 is disposed on the edge of the cup lid 2. The upper end of the air inlet pipe 303 forms an air inlet 201.

[0037] In another embodiment, the air inlet pipe 303 is disposed on the cup body 1, and the air outlet 202 is disposed on the cup lid 2. An air impact hole 306 is disposed at one end of the air inlet pipe 303. Specifically, the end of the air inlet pipe 303 away from the air source is a closed plate, and the air impact hole 306 is disposed on the closed plate. The closed plate can be integrally formed with the air inlet pipe 303, or it can be threaded or installed on the air impact pipe in other ways. The number of air impact holes 306 is 1 to 200, and the diameter of each air impact hole 306 is 0.3 to 2 mm.

[0038] In one embodiment, the negative ion generator body 301 is a container with an open lower end and a semi-closed upper end, and the air-striking plate 302 is fixed to the open section of the generator body 301. Preferably, the generator body 301 includes a top wall and side walls, the top wall is provided with an opening, the gain tube 304 is sealed and fixedly connected to the edge of the opening, and the air inlet pipe 303 passes through the opening and enters the air chamber. In one embodiment, the air-striking plate 302 is provided with an air-striking plate water inlet 3021 at a position avoiding the air-striking hole 306, for introducing water from the cup body 1 into the air-striking chamber 305.

[0039] In one embodiment, the generator body 301 of the negative oxygen ion generator 3 is a box structure, with an installation interface on its box wall for installing the air inlet pipe 303, and an air-smashing hole 306 on the box wall opposite to the air inlet pipe 303. The air-smashing plate 302 is fixedly connected to the box structure, forming an air-smashing chamber 305 between the air-smashing plate 302 and the generator body 301. The inner cavity of the generator body 301 forms a gas storage chamber 307. In one embodiment, the air inlet pipe 303 is connected to a gas source through a second one-way valve 7.

[0040] In one embodiment, the generator body 301 of the negative ion generator 3 is disposed at the bottom of the cup body 1, and the air inlet pipe 303 passes through the bottom wall of the cup body 1 and communicates with the external air passage. The generator body 301 of the negative ion generator 3 is a box structure, with an installation interface on its bottom wall for installing the air inlet pipe 303, and an air impact hole 306 on its top wall. The bottom surface of the box structure is attached to the bottom wall of the cup body 1, and an air cover 308 is fixedly connected to the top of the box structure. The air cover 308 is a semi-open structure, including a top plate and a side plate, wherein the top plate constitutes the air impact plate 302, and a connection port corresponding to the gain tube 304 is provided on the top plate for installing the gain tube 304; the space enclosed by the side plate forms a barrier to prevent the generated negative ion gas from leaking out from the side, ensuring that the gas is discharged from the gain tube 304. The air cover 308 and the generator body 301 are fixedly connected by a connecting rib 309. In this design, the distance between the side plate and the bottom surface of the cup body 1 is less than 5mm, and the height of the side plate is greater than 20mm. With this design, the generator body 301 is in close contact with the bottom of the cup body 1. Compared to the method of connecting to the generator body 301 from above via an air passage, the generator does not have a long rod-shaped structure (i.e., an air intake passage), resulting in higher overall rigidity. The vibration and noise generated by the gas impacting the generator body 301 are also reduced. Furthermore, in the method where air impacts the air-impact plate 302 and water downwards to form negative oxygen ions, the air-impact plate 302 has an opening for water connection, and the negative oxygen ion gas generation location is close to the connection port, making leakage easy. In this design, air impacts the air-impact plate 302 upwards, and the negative oxygen ion gas formed is directly discharged from the gain tube 304. Moreover, by setting up the side plate, it can be ensured that all generated negative oxygen ion gas is discharged through the gain tube 304 and does not move upwards through the water, avoiding loss of negative oxygen ion concentration.

[0041] In one embodiment, the dewatering mechanism 4 includes a first upper component 41 and a first lower component 42. The first upper component 41 includes a first annular wall 411, which is fixedly connected to or integrally formed with the cup lid 2, and the first upper component 41 and the cup lid 2 form a cavity. The first lower component 42 includes a base plate 421 and a second annular wall 422 vertically disposed on the edge of the base plate 421, the second annular wall 422 surrounding the first annular wall 411. The inlet 403 and the drain outlet 423 are disposed on the base plate 421, and the inlet 403 is formed between the first annular wall 411 and the second annular wall 422. The gain tube 304 passes through the inlet 403 and is sealed to the side wall of the inlet 403. In a preferred embodiment, the top end of the gain tube 304 is higher than the bottom end of the first annular wall 411 of the first upper component 41. Furthermore, after installation, the second annular wall 422 and the cup lid 2 are sealed. For example, the second annular wall 422 contacts the bottom surface of the cup lid 2, or contacts through a sealing element; or a raised ring is formed on the bottom surface of the cup lid 2, and the side of the second annular wall 422 contacts the side of the raised ring, or contacts through a sealing element. With this solution, the dewatering mechanism 4 is simple to manufacture and easy to install and remove. Moreover, the top of the gain tube 304 is higher than the bottom of the first annular wall 411. After the negative oxygen ion gas comes out from the gain tube 304, it will contact the inner side of the first annular wall 411 (and the bottom surface of the cup lid 2), then flow downward past the bottom of the first annular wall 411, and then enter the space between the first annular wall 411 and the second annular wall 422, where it will again rub against the sides of the first annular wall 411 and the second annular wall 422, and finally enter the air outlet 202 through the outlet 402. This greatly increases the flow path of the gas and allows for sufficient friction with the surfaces of each component. During this period, the moisture released from the negative oxygen ion gas flows along the side wall to the bottom plate 421 and is discharged from the drain outlet 423.

[0042] In one embodiment, a drainage groove 424 is provided on the base plate 421. The drainage groove 424 is located between the first annular wall 411 and the second annular wall 422 and surrounds the inlet 403. The drain outlet 423 is located at the bottom of the drainage groove 424.

[0043] In one embodiment, the water removal mechanism 4 is a box-shaped structure, including a box-shaped body 401 and an inlet 403, an outlet 402, and a drain outlet 423 disposed on the box-shaped body 401. The box-shaped body 401 includes a top plate, a bottom plate, and side plates. The inlet 403 is disposed on the side plate, the outlet 402 is disposed on the top plate, and the drain outlet 423 is disposed on the bottom plate. In one embodiment, the gain pipe 304 is inserted into the inlet 403 a certain distance. Preferably, the end of the gain pipe 304 extends into the inlet 403 by a distance greater than the distance between the outlet 402 and the side wall where the inlet 403 is located. That is, the end of the gain pipe 304 extends beyond the outlet 402, which allows the airflow path to form more bends and increases the length of the airflow path.

[0044] In one embodiment, the side plate is cylindrical, and the axial direction of the inlet 403 is tangential or substantially tangential to the cavity within the side plate. This allows airflow to enter the box-shaped structure tangentially, causing the negative oxygen ion-rich air to rotate within the box-shaped structure. Since water is denser than air, water is thrown against the inner wall of the box-shaped structure and discharged from the drain outlet 423 into the inner cavity of the cup body 1. In another embodiment, the inner wall of the side plate has a spiral groove, with the lower opening of the spiral groove opposite to the inlet 403 and the upper opening opposite to the outlet 402. In one embodiment, the spiral groove has at least half a turn, and the cross-section of the spiral groove is arc-shaped. This design further increases the contact friction area of ​​the airflow, improves the concentration of negative oxygen ions, and the spiral structure makes the centrifugal rotation of the airflow more pronounced, increasing the proportion of water thrown out.

[0045] In one embodiment, the inlet 403 is provided with an access nozzle 4031, which includes at least one bent section. One end of the access nozzle 4031 can be connected to the gain tube 304. For example, the access nozzle 4031 is L-shaped, including a horizontal section and an upwardly bent vertical section. One end of the horizontal section extends outward from the outside of the inlet 403, and one end of the vertical section is positioned upward close to the top plate. The outlet 402 is provided with a discharge nozzle 4021, which is a straight tube with one end contacting the inner wall of the top plate and the other end extending close to the bottom plate. In this way, there is a large overlap between the vertical section of the inlet 4031 and the outlet 4021, so that after the airflow enters the box-shaped structure from the inlet 4031, it must undergo more than two turns before entering the outlet 402. This allows for sufficient frictional contact with the inner walls of the box-shaped body 401, the inlet 4031, and the outlet 4021, increasing the concentration of negative oxygen ions. Furthermore, moisture is released during the back-and-forth turning, reducing the moisture content in the negative oxygen ion gas.

[0046] In one embodiment, the dewatering mechanism 4 includes a second upper component 43 and a second lower component 44. The second upper component 43 includes an annular plate 431 and an intermediate plate 432 disposed inside the annular plate 431, dividing the annular plate 431 into an upper space and a lower space. A first side of the annular plate 431 is sealed to the bottom surface of the cup lid 2. A vent hole is provided on the intermediate plate 432. The lower component is a plate with an inclined surface, which is sealed to the second side of the annular plate 431 at least partially. A gap 209 exists between the lower component and the second side of the annular plate 431 at the lowest position of the inclined surface. The gain tube 304 passes through the lower component into the lower space, and its top end is higher than the highest position of the gap 209. For example, the distance between the top end of the gain tube 304 and the intermediate plate 432 is 5-30 mm. The gain tube 304 is staggered from the vent hole of the intermediate plate. In this configuration, the negative oxygen ion airflow enters the lower space from the gain tube 304, changes direction within the lower space, and then enters the upper space through the vent. After flowing again in the upper space, it enters the outlet 402. Thus, the airflow in the lower space contacts and rubs against the intermediate plate 432 and the annular plate 431, increasing the generation of negative oxygen ions. The intermediate plate 432 also acts as a baffle 45, blocking a large amount of moisture and directing it towards or dripping onto the inclined surface of the second component 44, where it then flows out through the gap 209. In one embodiment, the bottom surface of the intermediate plate 432 includes multiple pointed micro-protrusions that can disrupt the surface tension of water droplets, allowing the precipitated moisture to drip off promptly. In another embodiment, the surface of the intermediate plate 432 includes at least one inclined portion, so that the inclined surface, combined with the pointed micro-protrusions, allows moisture to detach from the intermediate plate 432 in a timely manner.

[0047] In one embodiment, a baffle 45 is provided on the inner wall of the cup lid 2. The baffle 45 is located a certain distance away from the cup lid 2 and blocks the outlet 402 from the opening direction. This creates an airflow passage on the side between the baffle 45 and the cup lid 2. With this design, the airflow entering the upper space must change direction and speed before entering the outlet 402, further increasing the precipitation of moisture in the airflow. In one embodiment, the upper surface of the intermediate plate 432 includes an inclined surface, the lowest point of which is the edge of the through hole.

[0048] In this design, the high-moisture-content negative ion airflow first enters the lower space, where it is slightly obstructed in the flow channel (the outlet of the gain tube faces the section of the middle plate without vents, but the outlet of the gain tube is in the same direction as the vent). This allows water vapor in the airflow to be extracted without increasing the system's structural size or excessively reducing the size of the lower space. In the upper space, the outlet direction of the vent is perpendicular to the airflow path on the side of the baffle. This greater change in airflow direction allows for more thorough water extraction from the slightly lower-moisture-content negative ion airflow. This two-stage water extraction scheme, from top to bottom, more effectively extracts water and reduces the moisture content in the negative ion airflow.

[0049] In one embodiment, a water suction hole 3032 is laterally connected to one side of the air impact hole 306, and a water inlet hole 313 is provided on the generator body 301. A water inlet pipe 8 is connected between the water suction hole 3032 and the water inlet hole 313. For example, the air impact hole 306 is formed at one end of the air inlet pipe 303 (e.g., on a sealing plate), and the water suction hole 3032 is laterally arranged at one end of the air inlet pipe 303 with one end opening on the outer surface of the air inlet pipe 303. With this scheme, compressed air flows at high speed in the air impact hole 306, generating negative pressure. Water in the inner cavity of the cup body 1 is drawn into the air impact hole 306 through the water inlet hole 313, the water inlet pipe 8, and the water suction hole 3032. An air-water mixture is ejected from the air impact hole 306, and the air-water mixture impacts the water and the air impact plate 302, forming negative oxygen ion air. Experiments have shown that a ratio of 10% to 40% between the diameter of the water absorption hole 3032 and the diameter of the air impact hole 306 is more suitable. Because the water and air move together at high speed in the air-water mixture, the impact force on the water and air impact plate 302 inside the cup is greater. Moreover, when the small water molecules generated by the collision of water and air collide with the gas, the concentration of negative oxygen ions produced is higher (analyzed as the mechanism is that the concentration of negative oxygen ions produced by the collision of gas with small water droplets is higher than that produced by the collision with water surface (large water molecules)).

[0050] In one embodiment, the sealing plate is connected to the air inlet pipe 303 via threads. A through hole is provided on the air inlet pipe 303 corresponding to the water suction hole 3032. By screwing the sealing plate, the channel area at the connection point between the water suction hole 3032 and the through hole can be adjusted. This allows for adjustment of the effective area of ​​the water suction hole 3032, thereby adjusting the amount of water entering the air jet hole 306 as needed. Furthermore, due to the threaded connection, a tight connection between the sealing plate and the air inlet pipe 303 is maintained after screwing, preventing loosening. For example, when placing purified water and medicinal liquid in the cup, the channel area at the junction of the water suction hole 3032 and the through hole needs to be adjusted due to differences in the concentration and viscosity of the medicine and water. This can be achieved by screwing the sealing plate.

[0051] In one embodiment, a safety valve 203 is provided on the cup lid 2, and the safety valve 203 is installed between the first annular wall 411 and the second annular wall 422. It is used to open when the airflow pressure inside the cup body 1 exceeds a certain threshold to release pressure and prevent damage to the machine.

[0052] In one embodiment, the drain outlet 423 is provided with a drain pipe 425, and a one-way valve 5 is provided at the bottom end of the drain pipe 425. The drain pipe 425 is used to introduce water in the drain tank 424 into the inner cavity of the cup body 1, while the gas in the inner cavity of the cup body 1 cannot enter the water removal mechanism 4.

[0053] In one embodiment, the cup lid 2 is provided with a water inlet 204, and a water inlet cap 205 is provided on the water inlet 204, through which water can be added to the cup body 1. In one embodiment, the water inlet 204 is positioned corresponding to the drain outlet 423, and the water entering through the water inlet 204 directly enters the drain outlet 423, or further enters the drain pipe 425, and then enters the cup body 1 through the one-way valve 5. In one embodiment, the cup lid 2 is provided with a water inlet valve 208, through which water can be added to the cup body 1.

[0054] In one embodiment, the cup body 1 and the cup lid 2 are detachably and sealingly connected by fastening bolts 207, and a cup lid sealing ring 206 is provided at the connection. A water level gauge 6 is provided on the side of the cup body 1, which allows real-time observation of the water level inside the cup body 1, facilitating timely water replenishment.

[0055] In one embodiment, a cooling mechanism is provided in the gas path to cool the gas, thereby reducing the temperature of the negative oxygen ion gas and decreasing its moisture content. For example, the cooling mechanism can be installed on the outer side of the air inlet pipe 303 and the cup lid 2. In another embodiment, the cup lid 2 has a mounting groove, in which the cooling mechanism can be installed. Cooling from above achieves faster cooling, and installation and disassembly are convenient, simplifying the circuit layout.

[0056] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0057] Example 1:

[0058] See Figure 1 , Figure 2 and Figure 3 The air-jet negative ion generator of this embodiment includes a cup body 1, a cup lid 2, and a negative ion generating device 3.

[0059] The cup body 1 and the cup lid 2 are threaded together, and a cup lid sealing ring 206 is provided at the connection. The cup body 1 is a cylindrical container with an open top and a closed bottom. The open top of the cup body 1 is provided with an external thread for threading onto the cup lid 2. The cup lid 2 is a shallow container with an open bottom and a semi-closed top. The open bottom of the cup lid 2 is provided with an internal thread for threading onto the cup body 1. The upper surface of the cup lid 2 is provided with an air inlet, an air outlet 202, a water inlet 204, and a safety valve 203 that pass through the cup lid 2. The outside of the water inlet 204 is also provided with a water inlet cap 205 to block the water inlet 204. The negative oxygen ion generator 3 is set in the inner cavity of the cup body 1 and is submerged in water. The negative oxygen ion generator 3 is fixed to the center hole of the cup lid 2 through the air inlet pipe 303. The negative oxygen ion generator 3 includes a generator body 301, an air impact plate 302, an air inlet pipe 303 and a gain pipe 304. The gain pipe 304 is a straight hollow pipe, and the air inlet pipe 303 is a straight pipe with one end straight. A semi-enclosed hollow tube with one end open and the other closed has an air impact hole 306 at its closed end. An air impact plate 302 is installed 5-10 mm in front of the air impact hole 306 in the direction of air outlet. A water replenishment hole 3021 is provided on the air impact plate 302. An air inlet pipe 303 is fitted into a gain pipe 304 and connected to it as a whole by a connecting piece 3031. The air inlet pipe 303 and the gain pipe 304 are fixed together to the upper end face of the generator body 301. The generator tube is placed between the body and the air impact plate 302 to form an air impact chamber 305. The lower end of the annular gap between the air inlet pipe 303 and the gain pipe 304 is connected to the air impact chamber 305, and the upper end is connected to the water removal mechanism 4. The bottom of the water removal mechanism 4 is provided with a drain trough 424. The water removal mechanism 4 is a small volume cavity that is connected to the air outlet 202. A drain pipe 425 is provided below the drain trough 424. A one-way valve 5 is connected in series on the drain pipe 425. The drain pipe 425 introduces the water in the drain trough 424 into the inner cavity of the cup body 1, while the gas in the inner cavity of the cup body 1 cannot enter the water removal mechanism 4.

[0060] The working process of this embodiment is as follows:

[0061] Compressed air is input through inlet 201, ejected from air impact hole 306 through inlet pipe 303, impacting water and air impact plate 302 to form negative oxygen ion air. The negative oxygen ion air enters the water removal mechanism 4 through the annular gap between inlet pipe 303 and gain pipe 304, removing some moisture before being discharged from outlet 202. Testing shows that using an air pump with a flow rate of 30 liters / minute and a pressure of 0.15 MPa, the negative oxygen ion concentration reaches 40 million / cm³. 3 .

[0062] Example 2

[0063] See Figure 4 and Figure 5The difference between this embodiment and embodiment 1 is that: a water suction hole 3032 communicating with the air suction hole 306 is opened on the side wall of the air suction hole 306, a water inlet hole 313 is opened on the main body 301 of the generating device, and the water suction hole 3032 and the water inlet hole 313 are connected through the water inlet pipe 8. Other aspects are the same as the embodiment.

[0064] The working process of this embodiment is as follows:

[0065] Compressed air is input through inlet 201 and enters air impact hole 306 through inlet pipe 303. Since the diameter of air impact hole 306 is smaller than the inner diameter of inlet pipe 303, the compressed air flows at high speed in air impact hole 306, generating negative pressure. Water in the inner cavity of cup body 1 is drawn into air impact hole 306 through water inlet hole 313, water inlet pipe 8, and water suction hole 3032. A mixture of air and water is ejected from air impact hole 306. The mixture of air and water impacts the water and air impact plate 302, forming negative oxygen ion air. The negative oxygen ion air enters the water removal mechanism 4 through the annular gap between inlet pipe 303 and overflow pipe, removes some water, and is discharged from outlet 202. Tests show that using an air pump with a flow rate of 30 liters per minute and a pressure of 0.15 MPa, the concentration of negative oxygen ions reaches 50 million / cm³. 3 .

[0066] Example 3

[0067] See Figure 6 , Figure 7 , Figure 8 and Figure 9This embodiment of the air-jet negative ion generator includes a cup body 1, a cup lid 2, a negative ion generating device 3, a water removal mechanism 4, a water level gauge 6, and a second one-way valve 7. The cup body 1 and the cup lid 2 are detachably connected by fastening bolts 207, with a sealing ring at the connection point. The cup body 1 is a cylindrical container with an open top and a closed bottom. A water level gauge 6 is installed on the side of the cup body 1 for observing and controlling the water level inside the cup body 1. A screw hole is provided at the open top of the cup body 1 to mate with a screw hole on the cup lid 2, and the connection is secured with fastening bolts 207. The cup lid 2 is a flat plate with an annular groove on its lower surface for placing the sealing ring 206. A screw hole is provided through the cup lid 2 to mate with a screw hole on the cup body 1. A water inlet valve 208 and an air outlet 202 are also provided through the cup lid 2. The water removal mechanism outlet 402 of the water removal mechanism 4 is connected to the air outlet 202 on the cup lid 2. The negative ion generating device 3 is connected via... The air inlet pipe 303 is fixed to the bottom of the cup body 1 and connected to the air source through the second one-way valve 7. The negative oxygen ion generator 3 consists of a generator body 301, an air inlet pipe 303, a spiral gain pipe 304, an air cover 308, and a connecting rib 309. The inner cavity of the generator body 301 forms an air storage chamber 307. The generator body 301 and the air cover 308 are fixedly connected by the connecting rib 309, generally by welding, screw connection, or bonding. The generator body 301 and the air cover 308 form an air impact chamber 305. An air impact hole 306 is opened on the upper end face of the generator body 301. The lower end of the spiral gain pipe 304 is fixedly connected to the air cover 308 and communicates with the air impact chamber 305. The upper end is connected to the inlet 403 of the dehydration mechanism.

[0068] The dewatering mechanism 4 includes a box-shaped body 401, a dewatering mechanism outlet 4402, a dewatering mechanism inlet 403, and a drain pipe 425. The dewatering mechanism 4 is divided into a centrifugal dewatering mechanism 4 (see...). Figure 7 and Figure 8 ) and diffusion-type water removal mechanism 4 (see Figure 9 Both of these types of dehumidification mechanisms 4 can reduce the humidity of the negative oxygen ion air. Of course, other forms of dehumidification mechanisms 4 can also be used, or the humidity of the negative oxygen ion air can be reduced by lowering the temperature of the compressed air.

[0069] The working principle of this embodiment is as follows.

[0070] Compressed air enters the air storage chamber 307 through the inlet pipe 303 via the second one-way valve 7, and is ejected at high speed from the air impact hole 306, impacting the water and air cover 308 (the air cover 308 functions as the air impact plate 302), generating high-humidity negative oxygen ion air. This negative oxygen ion air rubs against and impacts the pipe wall in the spiral gain tube 304, significantly increasing the negative oxygen ion concentration. After some moisture is removed by the dehydration mechanism 4, it is finally discharged from the outlet 202. Testing shows that using an air pump with a flow rate of 30 liters / minute and a pressure of 0.15 MPa, the negative oxygen ion concentration reaches 50 million / cm³. 3 The higher the pressure and the greater the flow rate, the higher the concentration of negative oxygen ions.

[0072] See Figure 10 The air-jet negative ion generator of this embodiment includes a cup body 1, a cup lid 2, a negative ion generating device 3, a water level gauge 6, a second one-way valve 7, and a baffle 45. The difference from the previous embodiment is that:

[0073] ① The spiral gain tube 304 of Example 3 was replaced with a straight gain tube 304;

[0074] ② The specific structure of the water removal mechanism 4 is different, as it includes the aforementioned second upper component 43 and second lower component 44.

[0075] ③ A baffle 45 is installed in front of the air outlet 202 of the direct gain tube 304, a baffle 45 is installed at the air outlet 202 of the water removal mechanism 4, and a drain hole is installed at the bottom of the water removal mechanism 4.

[0076] Other aspects are the same as in the embodiments.

[0077] Tests showed that using an air pump with a flow rate of 30 liters / minute and a pressure of 0.15 MPa, the concentration of negative oxygen ions was 30 million / cm³. 3 .
