Referring to fig. 1 and 2, an oxygen anion generator 100 according to an embodiment of the present invention includes a bottle 110 and an oxygen anion generator 120. Wherein:

the bottle body 110 is used for containing a wetting liquid and can be a plastic bottle, a glass bottle or a metal cavity structure. The humidifying liquid is generally pure water, and can be replaced by a solution added with fragrance or medicines according to the personalized requirements of users. The bottle body 110 is generally provided with an openable bottle cap for conveniently adding the wetting liquid and conveniently cleaning the inside of the bottle body 110. In addition, a liquid feeding hole can be formed in the bottle body 110, and a hole plug can be arranged on the liquid feeding hole, so that liquid can be fed on the premise of not opening the bottle cap of the bottle body 110.

The negative oxygen ion generating device 100 can be applied to environments with violent vibration, such as an oxygen generator. Therefore, the bottle body 110 is generally formed in a cylindrical shape from a metal material such as stainless steel or aluminum alloy in order to have high reliability and long service life. The metal cylindrical structure is opaque, so that the liquid level change in the bottle body 110 cannot be visually observed, and therefore, the liquid cannot be added in time, which may affect the generation efficiency of negative oxygen ions.

In order to solve this problem, in the present embodiment, a liquid level gauge 111 communicating with the inside of the bottle body 110 is provided on the outside of the bottle body 110. The level gauge 111 may be a transparent glass or plastic tube with markings. Further, the glass tube or the plastic tube extends in the same direction as the axial direction of the bottle body 110. Therefore, the liquid level of the liquid level gauge 111 can be kept consistent with the liquid level inside the bottle body 110, and thus, whether liquid needs to be added into the bottle body 110 can be intuitively judged by observing the height of the liquid level gauge 111.

Further, the bottle body 110 is provided with an air outlet 101. When negative oxygen ions are generated in the bottle body 110, the negative oxygen ions can be led out through the air outlet end 101. The outlet 101 may be configured as a hole, an interface, a joint, etc. for conveniently guiding out the negative oxygen ions, the outlet 101 in this embodiment is generally configured with a conduit.

The negative oxygen ion generator 120 includes a body 121 and a hard impact member 122. The body 121 is generally formed of metal, such as stainless steel or aluminum alloy, and may be formed by die casting, cutting or injection molding, and has a strong impact resistance. The body 121 is generally integrally formed for strength, but may be assembled from several separately formed parts by welding or screwing for ease of processing. The hard striker 122 may be formed of a material having a high hardness, such as metal or ceramic, and may have a spherical, plate-like or columnar shape. When the hard impact piece 122 and the body 121 are made of the same material, they can be integrally formed. That is, one sidewall of the body 121 may serve as the hard impact member 122. The body 121 is accommodated in the bottle body 110. Therefore, when the bottle 110 is filled with a sufficient amount of wetting liquid, the body 121 can be immersed in the wetting liquid.

Further, the body 121 is formed with an impact chamber 102 communicating with the inside of the bottle body 110, and a hard impact member 122 is located in the impact chamber 102. The impingement chamber 102 is a hollow cavity structure and is not completely enclosed. Therefore, the wetting liquid in the bottle 110 can smoothly enter the impact chamber 102, and the negative oxygen ions generated in the impact chamber 102 can also smoothly enter the bottle 110 and finally be guided out from the air outlet 101.

The negative oxygen ion generator 120 is provided with an air inlet end 103 and an impact hole 104, and the impact hole 104 is configured to communicate the air inlet end 103 and the impact chamber 102. Also, the air flow emitted through the impingement holes 104 can be directed toward the hard impingement members 122. The inlet end 103 may be configured with a hole, a port, a connecting pipe, etc. for interfacing with a high pressure gas source, so that the high pressure gas in the high pressure gas source can enter the body 121 through the inlet end 103 and be emitted to the hard impact member 122 through the impact hole 104. Negative oxygen ions can be generated within the impingement chamber 102 by the high velocity gas stream impinging on the hard impingement member 122.

The number of the impingement holes 104 may be plural, and is generally less than 20. The impingement holes 104 may be round holes, square holes. In order to increase the impact force of the high velocity gas stream against the hard impact member 122. Specifically, in the present embodiment, the diameter of the impingement holes 104 is 0.1 mm to 1.5 mm.

Specifically, in the present embodiment, the air inlet pipe 123 is disposed at the air inlet end 103, and the air inlet pipe 123 extends to the outside of the bottle 110. The air inlet pipe 123 may be a hose or a rigid pipe. Since the air inlet pipe 123 extends to the outside of the bottle body 110, the air inlet end 103 can be conveniently butted with a high-pressure air source.

Further, in the present embodiment, the air inlet pipe 123 is a metal pipe, one end of the air inlet pipe 123 penetrates through the bottle 110, and the other end is connected to the body 121 by a screw thread.

Specifically, the air inlet pipe 123 may be assembled to a cap of the bottle body 110 and may be removed along with the cap. The metal tube itself has higher mechanical strength, and can better support the body 121 on the premise of not providing additional supporting members, so that the body 121 can be stably maintained in the bottle body 110 during operation. On the other hand, scale may be generated in the impact chamber 102 after a long time use, and the efficiency of generating negative oxygen ions may be affected. Therefore, the threaded connection facilitates disassembly of the body 121, thereby facilitating cleaning.

When the oxygen anion generator 100 is started, the body 121 of the oxygen anion generator 120 is immersed in the wetting liquid of the bottle 110, and the wetting liquid is filled in the impact chamber 102. The high pressure gas is emitted from the impact holes 104 to the hard impact member 122, and the liquid in the impact chamber 102 is driven to continuously impact the hard impact member 122. At this time, a scene of water flow impact at the natural waterfall is simulated in the impact chamber 102. The droplets are sheared by the violent impact to produce free electrons, which combine with oxygen molecules in the gas to produce negative oxygen ions in the impingement chamber 102. The generated negative oxygen ions enter the bottle body 110 along with the gas flow from the impact chamber 102 and are finally guided out from the gas outlet end 101.

Since the process of preparing negative oxygen ions by the negative oxygen ion generator 100 simulates the process of generating negative oxygen ions in natural environment, no radioactivity and high-energy radiation are involved, and no harmful substance is generated. Therefore, the negative oxygen ion generator 100 can significantly improve safety. Moreover, the negative oxygen ion generator 100 has a simple structure, and can generate negative oxygen ions by the impact of the high-pressure air source, so the cost is low.

In order to improve the efficiency of the negative oxygen ion generating device 100 in preparing negative oxygen ions, the structures and positions of the impact hole 104 and the hard impact piece 122 can be further improved. Such as:

referring to fig. 3, in the present embodiment, the negative oxygen ion generator 120 further includes an impact tube 124, one end of the impact tube 124 is communicated with the air inlet 103, and the other end extends into the impact chamber 102, a contraction section 1241 is formed on a portion of the impact tube 124 located in the impact chamber 102, a through hole 1242 is formed on the contraction section 1241, and the impact hole 104 is located at a distal end of the impact tube 124 away from the air inlet 103.

That is, the high pressure gas entering through the inlet end 103 enters the impingement tube 124, is transmitted through the impingement tube 124, and then is emitted from the impingement holes 104. The impingement tube 124 is typically a metal tube having a high stiffness and may be mounted inside the impingement chamber 102 by welding. The impact tube 124 may be a venturi tube, or a cylindrical metal tube with openings at both ends, and the impact tube 124 may be formed by contracting and opening the middle of the metal tube.

The portion of the impingement tube 124 extending into the impingement chamber 102 may be soaked with the wetting fluid in the impingement chamber 102. As the high pressure gas is conveyed along the impingement tube 124, the flow velocity of the gas stream will increase rapidly at the converging section 1241. According to the venturi theorem, the pressure inside the contraction section 1241 is rapidly reduced at this time, so that the internal-external pressure difference is generated. Under the action of the difference between the internal pressure and the external pressure, the wetting liquid in the impact chamber 102 can enter the impact tube 124 through the through hole 1242 and mix with the air flow conveyed in the impact tube 124. Therefore, the gas-liquid mixture is ejected from the impingement holes 104 and is finally ejected from the gas-liquid mixture toward the hard impingement member 122.

As shown in fig. 2, the hard impingement member 122 in this embodiment may be a ceramic or metal plate disposed at the bottom of the impingement chamber 102. The scene of the gas-liquid mixture impacting the hard impact piece 122 at high speed is closer to the scene of water flow impacting rocks at a waterfall in the natural environment. Thus, the efficiency of generating negative oxygen ions within the impingement chamber 102 may be increased to some extent. Moreover, after the impact generates the free electrons, the gas and the liquid are mixed more uniformly, so that the electrons and the oxygen are combined to generate negative oxygen ions.

Another example is as follows:

referring to fig. 4, in the second embodiment of the present invention, the hard impact member 122 is a blade rotatably disposed on the inner wall of the impact chamber 102, the impact hole 104 is disposed opposite to the blade, and the blade can rotate under the impact of the airflow emitted from the impact hole 104.

Specifically, the blade is generally a metal blade, and in order to improve the surface hardness of the blade, the surface of the blade can be plated with a ceramic film layer. The vanes may be mounted to the inner wall of the impingement chamber 102 by a rotating shaft. When high velocity airflow is directed from the impingement openings 104 to the blades, the blades are driven to rotate.

The rotation of the blades agitates the wetting fluid in the impingement chamber 102 and may cause it to form a vortex. Thus, when the high velocity airflow is directed from the impingement holes 104 to the hard impingement members 122, i.e., blades, it has not only a velocity in the direction of impingement, but also a rotational velocity in the circumferential direction as compared to the surface of the blade. In this way, more intense impact can be generated in the impact chamber 102, which is advantageous for improving the efficiency of generating negative oxygen ions. Moreover, the blade rotation also enables more uniform mixing of the gas with the wetting fluid in the impingement chamber 102. Therefore, after the electrons are impacted to generate free electrons, the electrons are more favorably combined with oxygen in the air to generate negative oxygen ions, and the generation efficiency of the negative oxygen ions is also favorably improved.

The negative oxygen ion generator 100 of the second embodiment differs from the negative oxygen ion generator 100 of the first embodiment mainly in the specific structure of the hard impact member 122. In addition, the present embodiment is also different from the first embodiment in that the impingement hole 104 is opened in the sidewall of the main body 121 and directly communicates with the air inlet 103.

It should be noted that the impingement openings 104 of the second embodiment may also be arranged in the manner of the impingement openings 104 of the previous embodiment. I.e. the impingement tube 124 is introduced and the impingement holes 104 are provided at the end of the impingement tube 124.

For another example:

referring also to fig. 5, in a third embodiment of the present invention, a hard impact member 122 is located in the middle of the impact chamber 102, and a plurality of impact holes 104 are distributed around the circumference of the hard impact member 122.

Specifically, the plurality of impingement holes 104 may communicate with the intake end 103 via an air passage or chamber. Because the plurality of impact holes 104 are distributed around the circumference of the hard impact piece 122, the high-pressure gas ejected from the impact holes 104 can drive the wetting liquid to impact the hard impact piece 122 from multiple directions, thereby being beneficial to improving the generation efficiency of negative oxygen ions.

Further, in the present embodiment, the body 121 includes an inner wall 1211 and an outer wall 1212, the inner wall 1211 encloses the impact chamber 102, the outer wall 1212 is sleeved on the inner wall 1211 and cooperates with the inner wall 1211 to form the high pressure chamber 105 communicating with the air inlet 103, and the impact hole 104 communicates with the high pressure chamber 105.

Specifically, the inner wall 1211 and the outer wall 1212 may have the same outer contour and are both hollow. The inner diameter of the outer layer cavity wall 1212 is larger than the inner diameter of the inner layer cavity wall 1211, so that a gap exists between the two, and the high-pressure air chamber 105 is formed. The impingement holes 104 may be a through hole structure that opens into the inner layer wall 1211. The high pressure gas entering through the inlet end 103 may be diverted within the high pressure plenum 105, thereby making the gas flow distribution to the plurality of impingement holes 104 more uniform. Furthermore, the body 12 is provided in a double-layered structure, which facilitates the circular arrangement of the punching holes 104.

Further, in this embodiment, the inner wall 1211 and the outer wall 1212 are cylindrical, and the hard impact member 122 is cylindrical and extends along the axis of the inner wall 1211. Thus, the body 121 can have better symmetry.

In particular, the hard impactor 122 may be a metal rod extending through the inner 1211 and outer 1212 chamber walls and into the impact chamber 102. The metal rod can be connected with the inner layer cavity wall 1211 and the outer layer cavity wall 1212 through a threaded fastening mode. In this case, the hard impact member 122 not only can be used for impacting the air flow or the water flow, but also can fix the inner wall 1211 and the outer wall 1212, so that the body 121 can be more conveniently molded.

The negative oxygen ion generator 100 of the third embodiment differs from the negative oxygen ion generator 100 of the first embodiment mainly in the specific structure of the hard impact member 122 and the arrangement and arrangement of the impact holes 104. It should be noted that the impingement openings 104 of the third embodiment may also be arranged in the manner of the impingement openings 104 of the first embodiment. I.e. the impingement tube 124 is introduced and the impingement holes 104 are provided at the end of the impingement tube 124.

Before the negative oxygen ion generator 100 is used to prepare the negative oxygen ions, a sufficient amount of wetting liquid is injected into the bottle 110 to soak the body 121 of the negative oxygen ion generator 120. High-pressure gas enters the body 121 from the gas inlet end 103 and is emitted to the hard impact piece 122 through the impact hole 104, so that liquid in the impact chamber 102 is driven to continuously impact the hard impact piece 122. The liquid drops are sheared by violent impact to generate free electrons, and the electrons are combined with oxygen molecules in the gas to generate negative oxygen ions. Therefore, the process of producing negative oxygen ions by the negative oxygen ion generator 100 simulates the process of producing negative oxygen ions in the natural environment, and thus harmful substances are not generated. Therefore, the negative oxygen ion generator 100 can significantly improve safety.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
