Description

Negative oxygen ion generator Technical Field

[0001] The present invention relates to the technical field of negative oxygen ion generators, in particular to a negative oxygen ion generator. Background Art

[0002] Negative oxygen ions enhance immunity, prevent and restore disease, regulate internal body functions, inhibit aging, activate and preserve liver and kidney function, stimulate peristalsis, stabilize intestinal pH, decompose harmful substances and carcinogens, promote excretion, improve lipid and sugar metabolism, facilitate digestion and absorption, produce metabolic hormones and vitamins, inhibit the proliferation of harmful bacteria and pathogens, and protect against infection. Therefore, negative oxygen ions are widely used in the medical device field. In addition, negative oxygen ions also have important value in the food, pharmaceutical, electronic semiconductor manufacturing, mechanical automation, clothing, printing, automotive manufacturing, petrochemical, environmental dust removal, environmental improvement, spray coating and electroplating, and other industries and production.

[0003] In the prior art, negative oxygen ion generators often use the principle of air excitation to generate negative oxygen ions, that is, using high-pressure air to impact liquid, thereby generating negative oxygen ions. Existing negative oxygen ion generators are mainly composed of a generator and an air compressor. The compressor provides a stable high-speed airflow for the negative oxygen ion generator. During use, the compressor needs to draw in external air, compress it to obtain high-pressure air, and then transmit the high-pressure air to the negative oxygen ion generator. The high-pressure air input by the compressor impacts the liquid in the generator, thereby generating negative oxygen ions. During this process, the operation of the compressor and generator will generate a lot of noise, which affects the user experience. Therefore, users often place the negative oxygen ion generator far away from the user to reduce noise. However, negative oxygen ions have a high mobility and are small ions that are beneficial to the human body. They have good biological activity and can move at high speed in the air. If the negative oxygen ion generator is placed too far away from the user, the concentration of negative oxygen ions inhaled by the user will be reduced, reducing the beneficial effects of negative oxygen ions on the human body. Summary of the Invention

[0004] An embodiment of the present invention provides a negative oxygen ion generator to solve the problem that the negative oxygen ion generator is placed far away from the user to avoid excessive noise during use, resulting in a low concentration of negative oxygen ions inhaled into the human body.

DETAILED DESCRIPTION

[0043] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0044] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] 1 to 11 , the present invention discloses a negative oxygen ion generator 10, which includes a first shell 11, a generator 12, a compressor 13, an air outlet 14, and a connecting rod assembly 15. The first shell 11 is provided with an air inlet 111a. The generator 12 is disposed in the first shell 11 and is used to generate negative oxygen ion gas. The compressor 13 is disposed in the first shell 11, with one end connected to the generator 12 and the other end connected to the air inlet 111a, for compressing air and delivering it to the generator 12. The air outlet 14 is connected to the generator 12 and is used to discharge the negative oxygen ion gas. The two ends of the connecting rod assembly 15 are rotatably connected to the first shell 11 and the air outlet 14, respectively, and the connecting rod assembly 15 is driven to move the air outlet 14 closer to or away from the first shell 11.

[0047] During the use of the negative oxygen ion generator 10, the compressor 13 first draws in air through the air inlet 111a, then compresses the air into high-pressure air and delivers it to the generator 12, causing the generator 12 to produce negative oxygen ion gas. In other words, the high-pressure gas flowing into the generator 12 impacts the liquid in the generator 12 to produce negative oxygen ion gas, and the negative oxygen ion gas in the generator 12 flows into the gas outlet 14 and is discharged. Since the connecting rod assembly 15 is rotatably connected to the first shell 11, the user can pull the connecting rod assembly 15 to move the gas outlet 14 closer to or away from the first shell 11. In other words, the user can pull the connecting rod assembly 15 as needed to bring the gas outlet 14 closer to the user, thereby absorbing a higher concentration of negative oxygen ions. Secondly, the user can place the first shell 11 at a distance from the user, and at the same time pull the connecting rod assembly 15 to bring the gas outlet 14 closer to the user, so as to achieve the effect of inhaling a higher concentration of negative oxygen ions while the noise around the user is low. Furthermore, the air outlet member 14 is rotatably connected to the connecting rod assembly 15, and the user can adjust the angle between the air outlet member 14 and the connecting rod assembly 15 as needed to meet the user's needs. For example, if the user needs to face the air outlet member 14 towards the face, the air outlet member 14 can be rotated relative to the connecting rod assembly 15 to adjust the pitch angle of the air outlet member 14 and face the user's face.

[0048] It should be noted that the liquid can be water. The negative oxygen ion generator 10 is roughly cylindrical, and can be cylindrical. The first shell 11 is roughly cylindrical, and the first shell 11 is provided with a plurality of air inlet holes 111a to allow more air to enter the first shell 11. One of the connecting rod assembly 15 and the first shell 11 is provided with a rotating shaft, and the other of the two is provided with an axial hole that cooperates with the rotating shaft to achieve a rotational connection between the two. In other embodiments, the connecting rod assembly 15 and the first shell 11 can adopt other rotational connection methods such as a hinge connection to achieve a rotational connection between the two. One of the connecting rod assembly 15 and the air outlet member 14 is provided with a rotating shaft, and the other of the two is provided with an axial hole that cooperates with the rotating shaft to achieve a rotational connection between the two. In other embodiments, the connecting rod assembly 15 and the air outlet member 14 can adopt other rotational connection methods such as a hinge connection to achieve a rotational connection between the two.

[0049] Referring to Figures 3 and 4, specifically, in some embodiments, the connecting rod assembly 15 includes a first connecting rod 151 and a second connecting rod 152 rotatably connected to the first connecting rod 151, the end of the first connecting rod 151 away from the second connecting rod 152 is rotatably connected to the first shell 11, and the air outlet piece 14 is rotatably connected to the end of the second connecting rod 152 away from the first connecting rod 151.

[0050] The negative oxygen ion generator 10 has a first direction D, which is perpendicular to the axial direction E of the negative oxygen ion generator 10. The rotation axis of the first connecting rod 151 and the first shell 11 is parallel to the first direction D; the rotation axis of the second connecting rod 152 and the first connecting rod 151 is parallel to the first direction D; the rotation axis of the air outlet member 14 and the second connecting rod 152 is parallel to the first direction D.

[0051] The first direction D is arranged along the axis of the rotation shaft. The first connecting rod 151 and the second connecting rod 152 are both rectangular parallelepipeds. The cooperation between the first connecting rod 151 and the second connecting rod 152 allows the user to inhale a high concentration of negative oxygen ion gas even when the air outlet member 14 is positioned relatively far from the first housing 11, thereby reducing the volume of the noise generated within the first housing 11 heard by the user. For example, the length of the first connecting rod 151 is A, and the length of the second connecting rod 152 is B. When the first connecting rod 151 and the second connecting rod 152 are pulled, the maximum distance between the air outlet member 14 and the first housing 11 is L, satisfying the relationship: L = A + B. When the user stops using the negative oxygen ion generator 10, the first connecting rod 151 can be retracted into the first housing 11, and the second connecting rod 152 can be embedded in the first housing 11 and abut against the outer wall of the first housing 11. In other words, the second connecting rod 152 and the first housing 11 abut to form a complete cylinder. Then rotate the air outlet piece 14 so that the air outlet piece 14 is located at the end of the first shell 11 away from the compressor 13, and one side is attached to the first shell 11, thereby reducing the radial size of the negative oxygen ion generator 10, so that the negative oxygen ion generator 10 can be folded into a cylindrical shape, which is convenient for storage and transportation. If the second connecting rod 152 protrudes or retracts into the first shell 11, foreign matter such as dust will enter the interior of the first shell 11, causing damage to the internal components of the negative oxygen ion machine and affecting the service life of the negative oxygen ion machine. Moreover, dust entering the interior of the first shell 11 can easily lead to a decrease in the purity of negative oxygen ions. If the second connecting rod 152 protrudes from the first shell 11, the second connecting rod 152 can be easily bumped by the user, causing the negative oxygen ion generator 10 to be knocked over, thereby causing damage to the generator 12 or the compressor 13. This structure is conducive to improving the service life of the negative oxygen ion generator 10.

[0052] It should be noted that one of the first connecting rod 151 and the second connecting rod 152 is provided with a rotation axis, and the other is provided with an axial hole that cooperates with the rotation axis to achieve a rotational connection between the two. In other embodiments, the first connecting rod 151 and the second connecting rod 152 can be rotatably connected using other connection methods, such as a hinge connection. The rotational connection between the first connecting rod 151 and the first housing 11 and the rotational connection between the second connecting rod 152 and the air outlet member 14 are both connected using the above-mentioned connection methods and will not be further described here.

[0053] 2 and 4 , in some embodiments, the gas outlet member 14 includes a second shell 141 rotatably connected to the connecting rod assembly 15 , and the second shell 141 is provided with a first gas outlet 141 a and a second gas outlet 142 a . The first gas outlet 141 a is connected to the generator 12 , and the second gas outlet 142 a is connected to the first gas outlet 141 a , and is used to discharge the negative oxygen ion gas.

[0054] The inner wall of the second shell 141 is surrounded to form a first noise reduction cavity 143 a . The first noise reduction cavity 143 a is connected to the first air outlet 141 a and the second air outlet 142 a .

[0055] In this embodiment, the second housing 141 comprises a curved surface (not shown), a first flat surface (not shown), and a second flat surface (not shown). The curved surface is located between the first and second surfaces. The first outlet 141a is located in the first surface, and the second outlet 142a is located in the second surface. The curved surface, the first and second surfaces enclose a first noise reduction chamber 143a, which effectively reduces the volume of transmitted noise. Sound waves are scattered within the first noise reduction chamber 143a at varying angles, reducing the energy of the sound waves during propagation and thus attenuating the sound. Furthermore, a recirculation hole is defined in the first surface, which is connected to the generator 12. When the negative oxygen ion gas enters the second housing 141 through the first outlet 141a, it collides with the curved surface of the second housing 141. Water droplets carried by the negative oxygen ion gas adhere to the curved surface, separating the water mist from the negative oxygen ion gas and producing higher-purity negative oxygen ion gas. Under the action of gravity, the water droplets attached to the curved surface will flow into the return port and into the generator 12 for recycling.

[0056] 6 and 7 , in some embodiments, the compressor 13 includes a body 131, a second body 132, and a sound absorbing member. The body 131 is respectively connected to the generator 12 and the air inlet 111a, and is provided with a receiving chamber 131a therein; the second body 132 is disposed in the receiving cavity; the sound absorbing member is disposed on the inner wall of the receiving chamber 131a, and the sound absorbing member (not shown in the figure) faces the direction of air flow in the receiving chamber 131a.

[0057] In this embodiment, the body 131 is cylindrical and is used to provide a fixed structure for the second body 132 and the sound-absorbing component. The second body 132 is fixedly connected to the body 131 and is used to compress the drawn-in air. The sound-absorbing component includes a plurality of sound-absorbing cottons, so that the sound-absorbing cottons can absorb the wind noise in the accommodating chamber 131a, thereby reducing the noise generated during the operation of the compressor 13. First, the second body 132 draws air into the second body 132 through the air inlet 111a for compression, and then delivers the compressed high-pressure air to the generator 12, so that the generator 12 generates negative oxygen ion gas. The negative oxygen ion gas in the generator 12 flows into the air outlet 14 and the negative oxygen ion gas is discharged. Secondly, the air enters the accommodating chamber through the air inlet 111a and flows through the second body 132 to cool the second body 132. During the process of the second main body 132 drawing in air for compression and transportation, and the air entering the accommodating chamber 131a and flowing through the compressor 13, the components in the accommodating chamber 131a will generate noise due to the intake or outflow of air. Therefore, the sound-absorbing cotton is arranged facing the direction of air flow in the accommodating chamber 131a, which can effectively absorb the noise generated by the intake or outflow of air.

[0058] In some embodiments, the body 131 may be provided with an air inlet 1311a, which is disposed in the accommodating chamber 131a and located at one end of the body 131 close to the generator 12, and includes at least two air inlets 1312a, and the air inlet 1311a is connected to the air inlet hole 111a through the air inlet 1312a; any air inlet 1312a is staggered with the adjacent air inlet 1312a, and the air passes through one air inlet 1312a in turn in the air inlet 1311a, so that the flow trajectory of the air in the accommodating chamber 131a is curved, and the sound absorbing component is disposed on the inner wall of the air inlet 1311a; the wind in the air inlet 1311a flows through the second body 132 through the air inlet 1312a to cool the second body 132.

[0059] Specifically, in this embodiment, the compressor 13 further includes a fan 133. The fan 133 is disposed within the accommodating chamber 131a and between the air inlet 1311a and the second body 132. The fan 133 is configured to draw air into the accommodating chamber 131a. The air inlet 1311a includes a first air inlet 1312a and a second air inlet 1312a. The first air inlet 1312a is located on a side of the inner wall of the air inlet 1311a away from the fan 133, while the second air inlet 1312a is located on a side of the inner wall of the air inlet 1311a closer to the fan 133. The first air inlet 1312a and the second air inlet 1312a are staggered. First, when fan 133 is activated, it draws air into fan 133. Specifically, the air enters air inlet 1311a through first air inlet 1312a, then enters fan 133 through second air inlet 1312a. The air is then discharged through fan 133 and flows through second body 132, thereby cooling second body 132. Compressor 13 may also include an air outlet duct (not shown). The air outlet duct is disposed within the accommodating cavity and is located at the end of body 131 away from fan 133. The air outlet duct includes a first air outlet (not shown) and a second air outlet (not shown). The first air outlet and the second air outlet are staggered, with the first air outlet located on the side of the inner wall of the air outlet duct closest to second body 132, and the second air outlet located on the side of the inner wall of the air outlet duct away from second body 132. Air flows through the first and second air outlets in the air outlet duct, forming a curved air flow path within the air outlet duct, reducing wind speed and thereby noise. The air outlet is connected to the air inlet 111a. Air flowing through the second body 132 flows into the air outlet duct through the first air outlet, then flows out of the body 131 through the second air outlet, and then out of the first housing 11 through the air inlet 111a. Sound-absorbing elements are provided on the inner walls of the air inlet duct 1311a and the air outlet duct to effectively reduce the noise generated by the compressor 13 due to air intake and exhaust.

[0060] 8-11 , in some embodiments, the generator 12 includes a third shell 121, a first main body 122 and a mixer 123. The third shell 121 is disposed in the first shell 11 and is provided with a third air outlet 121a, which is connected to the air outlet member 14. The first main body 122 is disposed in the third shell 121 and is provided with an air inlet channel 1221a and a liquid inlet channel 1222a, which is connected to the compressor 13. The mixer 123 is disposed in the third shell 121 and is connected to the first main body 122 at one end. The mixer 123 is provided with a second noise reduction chamber 1231a, and the air inlet channel 1221a and the liquid inlet channel 1222a are respectively connected to the second noise reduction chamber 1231a. The air introduced into the air inlet channel 1221a and the liquid introduced into the liquid inlet channel 1222a collide and mix in the second noise reduction chamber 1231a to generate negative oxygen ions.

[0061] In this embodiment, the shape of the mixer 123 is columnar, for example, cylindrical. One end of the air inlet channel 1221a is connected to the compressor 13 so that high-pressure air is introduced into the air inlet channel 1221a, and the other end is connected to the mixer 123, so that liquid is sucked into the liquid inlet channel 1222a. First, high-pressure air is introduced into the air inlet channel 1221a. The pressure is lower where the flow rate is high. Therefore, a negative pressure is formed at the end of the mixer 123 close to the air inlet channel 1221a, thereby causing the liquid to be sucked into the liquid inlet channel 1222a, forming a siphon effect. The high-pressure air in the air inlet channel 1221a impacts the liquid flowing out of the liquid inlet channel 1222a to generate negative oxygen ions. Specifically, the third shell 121 is provided with a water storage chamber 127a. The water storage chamber 127a is provided at one end of the third shell 121 away from the first main body 122, and the water storage chamber 127a is connected to the second noise reduction chamber 1231a. One end of the liquid inlet channel 1222a is connected to the water storage chamber 127a, and the other end is connected to the second noise reduction chamber 1231a. When the air in the air inlet channel 1221a rushes into the second noise reduction chamber 1231a, a siphon phenomenon is formed in the second noise reduction chamber 1231a, so that the water in the water storage chamber 127a continuously flows into the second noise reduction chamber 1231a, so that the air in the air inlet channel 1221a continuously impacts the liquid to produce negative oxygen ions.

[0062] High-pressure air from air inlet channel 1221a impacts the liquid flowing from liquid inlet channel 1222a, generating negative oxygen ions. Due to the large amplitude of the air impacting the liquid, the noise from generator 12 is excessive. Therefore, mixer 123 includes a second noise reduction chamber 1231a, which effectively reduces the volume of the transmitted sound. Sound waves are scattered within second noise reduction chamber 1231a at varying angles, reducing the energy of the sound waves during propagation and thus attenuating the sound.

[0063] In some embodiments, the generator 12 may further include a Laval tube (not shown in the figure), which is integrally formed with the side wall of the air inlet channel 1221a and is located at one end of the air inlet channel 1221a close to the mixer 123. The Laval tube is connected to the mixer 123. The Laval tube is sleeved on the side wall of the end of the liquid inlet channel 1222a, and there is a gap between the Laval tube and the end of the side wall of the liquid inlet channel 1222a. This structure can increase the flow rate of air at the end of the air inlet channel 1221a, reduce the pressure here, and thereby cause the liquid to be sucked into the liquid inlet channel 1222a, forming a siphon effect.

[0064] It should be noted that the internal structure of the Laval tube is the same as that of the jet tube of a rocket launch station, and both are made using the Laval nozzle principle.

[0065] The generator 12 includes a first curved sound reduction cover 124, which is arranged in the third shell 121 and is sleeved on the end of the mixer 123 away from the first main body 122. The first curved sound reduction cover 124 forms a third noise reduction cavity 1241a. The end of the first curved sound reduction cover 124 close to the mixer 123 is provided with a fourth air outlet 1242a. The fourth air outlet 1242a and the second noise reduction cavity 1231a are respectively connected to the third noise reduction cavity 1241a, and the fourth air outlet 1242a is connected to the third air outlet 121a.

[0066] In this embodiment, the shape of the first curved sound reduction cover 124 is roughly a combination of a cone and a cylinder, and the end with a smaller diameter is sleeved on the outer wall of the mixer 123. There are more than two fourth air outlet holes 1242a, which are spaced apart at one end of the first curved sound reduction cover 124 close to the mixer 123, so as to allow negative oxygen ions to flow out through the fourth air outlet holes 1242a to the third air outlet holes 121a, and then discharged from the third shell 121 to flow to the air outlet part 14.

[0067] The inner wall of the third noise reduction chamber 1241a is an arc surface. The noise generated in the mixer 123 undergoes the first step of processing in the second noise reduction chamber 1231a. The processed noise sound waves are transmitted to the third noise reduction chamber 1241a. The sound waves are scattered in the second noise reduction chamber 1231a. Due to the setting of the arc surface, the scattering angles are different, so that the energy of the sound waves is reduced during the propagation process, thereby weakening the sound.

[0068] In some embodiments, the generator 12 may further include a condensation net 128, which is fixedly connected to the first arc-shaped sound reduction cover 124 and is located inside the first arc-shaped sound reduction cover 124, so that the mixed gas mist generated in the mixer 123 collides with the condensation net 128 along the axial direction E of the negative oxygen ion generator 10, and the mixed gas mist collides with the condensation net 128 to form water droplets, so as to achieve the separation of negative oxygen ion gas and water mist, increase the concentration of negative oxygen ions, and the separated negative oxygen ion gas flows out through the fourth air outlet 1242a.

[0069] In some embodiments, the generator 12 may further include a second curved sound reduction cover 125, which is mounted on one end of the mixer 123 close to the first main body 122. The second curved sound reduction cover 125 is provided with a fifth air outlet 1251a. The first curved sound reduction cover 124, the third shell 121 and the second curved sound reduction cover 125 are arranged to form a fourth noise reduction chamber 1243a. The second curved sound reduction cover 125 and the third shell 121 are arranged to form a fifth noise reduction chamber 1252a. The fifth noise reduction chamber 1252a is connected to the fourth noise reduction chamber 1243a through the fifth air outlet 1251a, and the fifth noise reduction chamber 1252a is connected to the third air outlet 121a.

[0070] In this embodiment, the second curved sound-reducing cover 125 is truncated cone-shaped, with its smaller diameter end fitting over the outer wall of the mixer 123 and connected to the smaller diameter end of the first curved sound-reducing cover 124. In other words, the second curved sound-reducing cover 125 surrounds the end of the mixer 123 closest to the first body 122. The first curved sound-reducing cover 124, the third shell 121, and the second curved sound-reducing cover 125 enclose a fourth noise reduction chamber 1243a, while the second curved sound-reducing cover 125 and the third shell 121 enclose a fifth noise reduction chamber 1252a. Both the fourth and fifth noise reduction chambers 1243a and 1252a achieve noise reduction by scattering sound waves within the chambers, thereby reducing the energy of the sound waves and ultimately lowering the volume of the noise. The fifth air outlet 1251a is provided at the larger diameter end of the second curved sound reduction cover 125 and is used to connect the fourth noise reduction chamber 1243a and the fifth noise reduction chamber 1252a. The fifth noise reduction chamber 1252a is connected to the third air outlet 121a. In some embodiments, the mixer 123 is provided with a reflux port, which is connected to the fifth noise reduction chamber 1252a. The shape of the second curved sound reduction cover 125 facilitates liquid reflux. For example, negative oxygen ion gas carrying water mist collides with the second curved sound reduction cover 125 and condenses into water droplets. The second curved sound reduction cover 125 can guide the water droplets to the reflux port and then enter the mixer 123. The water droplets are then struck again by the high-pressure air in the air inlet channel 1221a to produce negative oxygen ions, thereby achieving liquid recycling.

[0071] Thus, the path of negative oxygen ion gas from generation to discharge from the housing is as follows: First, air inlet channel 1221a rushes into the second noise reduction chamber 1231a, creating a negative pressure in the second noise reduction chamber 1231a. This causes the liquid in the water storage chamber 127a to be drawn into the second noise reduction chamber 1231a through the liquid inlet channel 1222a. In the second noise reduction chamber 1231a, the air impacts the liquid flowing out of the liquid inlet channel 1222a, thereby generating a negative oxygen ion mixed mist. Some of the negative oxygen ions flow through the fourth air outlet 1242a to the fourth noise reduction chamber 1243a, then through the fifth air outlet 1251a to the fifth noise reduction chamber 1252a, and then through the third air outlet 121a to the first air outlet 141a of the air outlet member 14, and finally discharged through the second air outlet 142a. Another portion of the negative oxygen ion mixed mist impacts the condensation net 128, forming water droplets. The separated negative oxygen ions pass through the condensation net 128 and then flow out through the fourth air outlet 1242a. Finally, they pass through the fourth noise reduction chamber 1243a, the fifth air outlet 1251a, the fifth noise reduction chamber 1252a, and the third air outlet 121a, flowing into the air outlet member 14 and being discharged through the second air outlet 142a. Due to the gap between the first curved sound-reducing cover 124 and the third shell 121, the negative oxygen ion gas will impact the third shell 121, the first curved sound-reducing cover 124, or the second curved sound-reducing cover 125 during the outflow process, condensing into water droplets. The water droplets can then flow through the gap between the first curved sound-reducing cover 124 and the third shell 121 into the water storage chamber 127a. A reflux hole is provided in the air outlet member 14 and is connected to the water storage chamber 127 a . Water droplets condensed in the air outlet member 14 can flow to the water storage chamber 127 a through the reflux hole, so that the liquid is recycled.

[0072] In some embodiments, the generator 12 includes a fourth housing 126, which defines a receiving cavity. One end of the third housing 121 is disposed within the receiving cavity. The mixer 123, first curved sound-reducing cover 124, second curved sound-reducing cover 125, condensing net 128, and portions of the first body 122, such as the liquid inlet channel 1222a and one end of the air inlet channel 1221a, within the third housing 121 are all located within the fourth housing 126. This double-layered housing arrangement effectively blocks the propagation of noise, achieving a double-layer sound insulation and absorption effect.

[0073] The present invention discloses a negative oxygen ion generator 10, which includes a first housing 11, a generator 12, a compressor 13, an air outlet 14, and a connecting rod assembly 15. The first housing 11 is provided with an air inlet 111a. The generator 12 is disposed within the first housing 11 and is used to generate negative oxygen ion gas. The compressor 13 is disposed within the first housing 11, one end of the compressor 13 being connected to the generator 12 and the other end of the compressor 13 being connected to the air inlet 111a, for compressing air and delivering it to the generator 12. The air outlet 14 is connected to the generator 12 and is used to discharge the negative oxygen ion gas. The connecting rod assembly 15 is rotatably connected to the first housing 11 and the air outlet 14 at both ends, respectively. The connecting rod assembly 15 is driven to move the air outlet 14 closer to or further away from the first housing 11. During use of the negative oxygen ion generator 10, the compressor 13 first draws in air through the air inlet 111a, then compresses the air into high-pressure air and delivers it to the generator 12, causing the generator 12 to generate negative oxygen ion gas. The negative oxygen ion gas in the generator 12 flows into the air outlet 14 and is discharged. Since the connecting rod assembly 15 is rotatably connected to the first shell 11, the user can pull the connecting rod assembly 15 to move the air outlet 14 closer to or away from the first shell. In other words, the user can pull the connecting rod assembly 15 as needed to bring the air outlet 14 closer to the user, thereby absorbing a higher concentration of negative oxygen ions. Secondly, the user can place the first shell 11 at a distance from the user and pull the connecting rod assembly 15 to bring the air outlet 14 closer to the user, thereby achieving the effect of inhaling a higher concentration of negative oxygen ions while the noise around the user is low. Moreover, the air outlet 14 is rotatably connected to the connecting rod assembly 15, and the user can adjust the angle between the air outlet 14 and the connecting rod assembly 15 as needed to meet the user's needs. For example, if the user needs to face the air outlet 14 to the face, the air outlet 14 can be rotated relative to the connecting rod assembly 15 to adjust the pitch angle of the air outlet 14 and face the user's face.
