[0035] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Such as Figure 1 , Figure 6 and Figure 7As shown in the figure, a negative oxygen ion atomizing humidifying oxygen generator includes an oxygen generator main body 1, a housing 2, an atomizing humidifying component 3, a negative oxygen ion generator, and an output pipe 4. The oxygen generator main body 1 has an oxygen outlet pipe 11; the housing 2 is connected to the outer wall of the oxygen generator main body 1 and includes a lower housing 22 and an upper housing 21 that can be covered with the lower housing 22; the atomizing humidifying component 3 is arranged inside the housing 2 and includes a liquid storage bottle 33, a piezoelectric ceramic sheet 34, a control board 5, and a liquid guide 31. The liquid storage bottle 33 is connected to the upper housing 21. One end of the liquid guide 31 is inserted into the liquid storage bottle 33, and the other end is matched with the piezoelectric ceramic sheet 34 to transfer the liquid in the liquid storage bottle 33 to the piezoelectric ceramic sheet 34. The piezoelectric ceramic sheet 34 has a first connection end 35. The control board 5 is arranged in the lower housing 22 and has a second connection end 51. After the upper housing 21 and the lower housing 22 are covered and connected, the first connection end 35 is in contact and cooperation with the second connection end 51 so that the control board is connected to the piezoelectric ceramic sheet 34, and the piezoelectric ceramic sheet 34 can be controlled to vibrate at a high frequency to atomize water molecules; the negative oxygen ion generator is arranged inside the housing 2 and is used to generate negative oxygen ions and mix them with the atomized water molecules to form negative oxygen ion atomized gas; one end of the output pipe 4 is connected to the upper housing 21, and the other end is communicated with the oxygen outlet pipe 11 and is used to transport the negative oxygen ion atomized gas to be mixed with the oxygen in the oxygen outlet pipe 11.

[0037] Specifically, the end of the oxygen outlet pipe 11 can be connected to a breathing mask or a nasal catheter. The oxygen generator main body 1 is responsible for generating oxygen through the oxygen generator inside it (such as molecular sieve adsorption method, electrolytic water method, etc.) and transporting the oxygen to the user for inhalation through the oxygen outlet pipe 11. The liquid storage bottle 33 is used to store the liquid to be atomized, such as pure water, distilled water, or a specific medicinal liquid. When the control board 5 is connected to the piezoelectric ceramic sheet 34 through the first connection end 35 and the second connection end 51, ultrasonic signals will be generated when the control board 5 works, and these signals are transmitted to the piezoelectric ceramic sheet 34; after receiving the ultrasonic signals, the piezoelectric ceramic sheet 34 will start to vibrate at a high frequency. This high-frequency vibration will break the water molecules in contact into tiny droplets. The atomized water molecules adsorb the negative oxygen ions generated by the negative oxygen ion generator to form negative oxygen ion atomized gas, which then mixes with the oxygen in the oxygen outlet pipe 11 through the output pipe 4 and is finally discharged from the end of the oxygen outlet pipe 11 for the user to inhale.

[0038] The atomized water molecules can increase the humidity in the air and make oxygen easier to be absorbed by the human body. At the same time, the combination of negative oxygen ions and oxygen can also improve the biological utilization rate of oxygen. Negative oxygen ions can adsorb harmful substances such as dust and bacteria in the air and make them settle, thereby improving the breathing environment.

[0039] The atomization and humidification component 3 of the present utility model cooperates with the negative oxygen ion generator to generate negative oxygen ion atomized gas, and forms a tee structure between the output pipe 4 and the oxygen outlet pipe 11, mixing the negative oxygen ion atomized gas with the oxygen in the oxygen outlet pipe 11 and transporting it to the user, achieving the purpose of humidifying the oxygen and purifying the oxygen and the oxygen delivery pipe. At the same time, it can also be used alone to generate water mist through the piezoelectric ceramic sheet 34, which can effectively increase the humidity in the air and provide a more comfortable environment for the user. Through the mixing of the negative oxygen ion generator and the atomized water molecules, it can provide an air environment rich in negative oxygen ions for the user or purify the oxygen produced by the oxygen generator, which helps to improve the respiratory health of the user. And when the oxygen generated by the oxygen generator is transported outward through the oxygen outlet pipe 11, a negative pressure is formed in the output pipe 4, which can strengthen the flow rate of the negative oxygen ion atomized gas flowing into the oxygen outlet pipe 11 and achieve a better mixing effect with the oxygen.

[0040] In some embodiments of the present application, as Figure 8 shown, the liquid guide 31 includes a water suction pipe 311 and an elastic member 312. The water suction pipe 311 is sleeved on the water absorption cotton swab 312 and inserted into the liquid storage bottle 33. The water suction pipe 311 is provided with through holes for the liquid in the liquid storage bottle 33 to flow to the water absorption cotton swab 312, and the liquid is transmitted to the piezoelectric ceramic sheet 34 through the water absorption cotton swab 312.

[0041] Specifically, the water suction pipe 311 and the water absorption cotton swab 312 constitute an efficient liquid conduction structure. First, the water suction pipe 311 is inserted into the liquid storage bottle 33, so that one end of the water suction pipe 311 is in direct contact with the liquid in the liquid storage bottle 33. The water suction pipe 311 is provided with through holes to allow the liquid in the liquid storage bottle 33 to flow into the water absorption cotton swab 312 by capillary action or gravity. The water absorption cotton swab 312 has excellent water absorption and water retention properties, and can quickly absorb and store the liquid flowing in through the water suction pipe 311. At the same time, it can effectively transfer the liquid from one end to the other end, that is, transfer the liquid in the liquid storage bottle 33 to the part in contact with the piezoelectric ceramic sheet 34. When the piezoelectric ceramic sheet 34 works, due to the action of high-frequency vibration, the liquid in contact with it is atomized. And since the water absorption cotton swab 312 has transferred the liquid to the vicinity of the piezoelectric ceramic sheet 34, the piezoelectric ceramic sheet 34 can start working immediately without waiting for the liquid to flow to its surface by itself. The water retention property of the water absorption cotton swab 312 ensures that even under the condition of high-frequency vibration of the piezoelectric ceramic sheet 34, it can continuously and stably provide enough liquid for it, thus ensuring the stability and continuity of the atomization effect. Through the coordinated use of the water absorption cotton swab 312 and the water suction pipe 311, efficient liquid conduction from the liquid storage bottle 33 to the piezoelectric ceramic sheet 34 is achieved, greatly improving the working efficiency of the oxygen generator.

[0042] In some embodiments of the present application, an elastic member 32 is provided between the bottom end of the absorbent cotton swab 312 and the inner side of the water absorption pipe 311. Specifically, the elastic member 32 is a spring. When the absorbent cotton swab 312 is subjected to the pressure of the liquid or its own gravity during the water absorption process, a slight deformation may occur at its bottom. At this time, the elastic member 32 plays its buffering role. It can absorb these slight deformations, prevent the absorbent cotton swab 312 from being damaged due to excessive pressure, and at the same time ensure the stability of liquid transmission. The setting of the elastic member 32 can also fix the absorbent cotton swab 312 in the water absorption pipe 311 to prevent it from moving or falling off during operation.

[0043] In some embodiments of the present application, the upper housing 21 has a threaded hole 214, and the mouth of the liquid storage bottle 33 is provided with an external thread 331. The liquid storage bottle 33 is detachably arranged on the upper housing 21 through the cooperation of the external thread 331 and the threaded hole 214. Specifically, the upper housing 21 is designed with a threaded hole 214, and the mouth of the liquid storage bottle 33 is equipped with a corresponding external thread 331. The liquid storage bottle 33 is rotated so that its external thread 331 is tightly fitted with the threaded hole 214 of the upper housing 21. Due to the use of the threaded connection method, the liquid storage bottle 33 can be conveniently connected or detached from the upper housing 21. When it is necessary to add or replace the liquid in the liquid storage bottle 33, the user only needs to rotate the liquid storage bottle 33 counterclockwise to easily remove it from the upper housing 21; after adding or replacing the liquid, rotate the liquid storage bottle 33 clockwise to fix it on the upper housing 21 again. The threaded connection method ensures a tight connection between the liquid storage bottle 33 and the upper housing 21, thereby effectively preventing liquid leakage during use. This design not only improves the safety of the device but also ensures the effective utilization of the liquid. The detachable design of the liquid storage bottle 33 enables the user to easily add and replace the liquid without complex tools or operations. This greatly improves the usability of the device and the user experience. Due to the self-locking property of the threaded connection, the liquid storage bottle 33 can remain stable after connection and is not easily detached or loosened due to external factors (such as vibration or shaking). This ensures the stability and reliability of the device during use.

[0044] In some embodiments of the present application, the liquid storage bottle 33 has a water injection port near the mouth of the liquid storage bottle 33, and water can be injected into the liquid storage bottle 33 through the water injection port. Specifically, the design of the water injection port allows the user to directly inject the required liquid (such as pure water or distilled water) into the liquid storage bottle 33 through this port. The user only needs to connect the water source to the water injection port to inject the liquid into the liquid storage bottle 33. By directly injecting water, the user can more intuitively control the injection volume of the liquid, thereby avoiding usage problems caused by inaccurate liquid levels. At the same time, the convenient water injection operation also improves the overall user experience. When replenishing the liquid in the liquid storage bottle 33, the water injection can be completed without disassembling it.

[0045] In some embodiments of the present application, the oxygen generator main body 1 and the lower housing 22 are detachably connected. Specifically, by designing the oxygen generator main body 1 and the lower housing 22 as detachable modules, users can selectively use or disassemble these two parts according to their needs. For example, when the user only needs the oxygen generation function, they can only use the oxygen generator main body 1; and when it is necessary to increase the humidity of the oxygen or inhale medicament atomization, the atomization and humidification assembly 3 can be connected to the oxygen generator main body 1 for use. Since the oxygen generator main body 1 and the atomization and humidification assembly 3 can be separated, when one of the parts fails or needs maintenance, the user can replace or repair this part separately without replacing the entire device, improving the convenience of maintenance. At the same time, it is also convenient for cleaning and disinfection, reducing the risk of cross-infection and improving the hygienic safety of use.

[0046] In some embodiments of the present application, as Figure 3 and Figure 4 shown, a clamping plate 12 is provided on the outer wall of the oxygen generator main body 1, clamping grooves 121 are formed on opposite sides of the clamping plate 12, a clamping portion 221 is provided on the outer wall of the lower housing 22, and the clamping portion 221 can be inserted into the clamping grooves 121 on both sides and abuts against the top of the clamping plate 12. Specifically, in the design of the oxygen generator, a clamping plate 12 is provided on the outer wall of the oxygen generator main body 1, and clamping grooves 121 are formed on opposite sides of the clamping plate 12. The outer wall of the lower housing 22 is designed with a clamping portion 221, and the clamping portion 221 can match the clamping grooves 121 on the clamping plate 12. When it is necessary to connect the oxygen generator main body 1 and the lower housing 22, the user can align the clamping portion 221 of the lower housing 22 and insert it into the clamping grooves 121 on both sides of the clamping plate 12 of the oxygen generator main body 1 until the clamping portion 221 completely abuts against the top of the clamping plate 12. Through this design, a stable connection structure is formed between the oxygen generator main body 1 and the lower housing 22. The design of the clamping plate 12 and the clamping portion 221 makes the connection between the oxygen generator main body 1 and the lower housing 22 simple and fast. The user can easily complete the installation or disassembly without using complex tools or performing cumbersome operations.

[0047] In some embodiments of the present application, as Figure 2 shown, a fixing frame 13 is provided on the outer wall of the oxygen generator main body 1, the fixing frame 13 has a receiving groove 131, and the housing 2 is placed in the receiving groove 131. Specifically, in the design of the oxygen generator, a fixing frame 13 is provided on the outer wall of the oxygen generator main body 1, and the fixing frame 13 has a receiving groove 131 for placing the housing 2. When it is necessary to connect the housing 2 and the oxygen generator main body 1, the user only needs to place the housing 2 in the receiving groove 131 of the fixing frame 13 to complete the fixation between the atomization and humidification assembly 3 and the oxygen generator main body 1. Since the shape and size of the receiving groove 131 match those of the housing 2, the housing 2 can be stably placed in the receiving groove 131 and form a fixed connection with the oxygen generator main body 1.

[0048] In some embodiments of the present application, a flexible layer is provided on one side inside the fixing frame 13, and the outer shell 2 is in interference fit with the accommodating groove 131 through the flexible layer. Specifically, when the atomizing humidifying component 3 needs to be installed into the accommodating groove 131 of the fixing frame 13, the flexible layer plays a key role. Due to the certain elasticity and deformation ability of the flexible layer, it can enable an interference fit to be formed between the outer shell 2 and the accommodating groove 131.

[0049] Specifically, when the outer shell 2 is pushed into the accommodating groove 131, the flexible layer will be deformed by the extrusion of the outer shell 2. This deformation causes the flexible layer to closely adhere to the outer wall of the outer shell 2, thereby achieving an interference fit between the outer shell 2 and the accommodating groove 131. The interference fit means that the fit clearance between the two is extremely small, thus ensuring the stability and sealing performance of the connection. The design of the interference fit ensures that the connection between the outer shell 2 and the fixing frame 13 is stable and reliable, and is not prone to loosening or falling off. This helps to improve the stability of the oxygen generator during operation and reduce failures and downtime caused by connection problems. The existence of the flexible layer can also buffer external impacts and vibrations to a certain extent, further protecting the atomizing humidifying component 3 from damage.

[0050] In some embodiments of the present application, as Figure 5 shown, the output pipe 4 and the upper outer shell 21 are detachably connected. The upper outer shell 21 has an air outlet 213 for connecting the output pipe 4. A sliding groove 211 is opened at the top of the upper outer shell 21. The air outlet 213 is located at the bottom of the sliding groove 211, and a slider 212 is slidably arranged in the sliding groove 211. The slider 212 can slide to close and open the air outlet 213.

[0051] Specifically, the output pipe 4 and the upper outer shell 21 are designed to be detachably connected. The upper outer shell 21 is provided with an air outlet 213 for connecting the output pipe 4, and the air outlet 213 is located at the bottom of the sliding groove 211 opened at the top of the upper outer shell 21. A slider 212 is slidably arranged in the sliding groove 211, and the slider 212 can slide to close or open the air outlet 213.

[0052] Specifically, when it is necessary to connect the output pipe 4, the user can align and connect the output pipe 4 with the air outlet 213. At this time, the slider 212 is at a certain position in the sliding groove 211, so that the air outlet 213 remains open, allowing the negative oxygen ion atomized gas to pass through. When it is necessary to disconnect the output pipe 4 or close the air outlet 213, the user can slide the slider 212 to close the air outlet 213. The sliding path of the slider 212 in the sliding groove 211 will pass through the air outlet 213. When the slider 212 slides to the position of the air outlet 213, it will completely cover the air outlet 213, thus achieving the closing effect. Through the design of detachable connection, the user can easily connect or disconnect the output pipe 4 according to needs, improving the flexibility of the device. The design of the slider 212 allows the user to close or open the air outlet 213 at any time according to needs, further increasing the flexibility of the device.

[0053] In some other embodiments of the present application, the liquid storage bottle 33 is transparent. Specifically, since the liquid storage bottle 33 is transparent, the user can intuitively see the liquid level in the bottle, so as to know the remaining water volume in the liquid storage bottle 33 in real time. This immediate visual feedback can help the user make more accurate decisions, such as whether to add water or when to replace the liquid storage bottle 33. The transparent liquid storage bottle 33 makes the internal situation clear at a glance, and the user can more easily discover and remove the dirt or residues inside. This helps to keep the device clean and hygienic and reduces the possibility of bacterial growth. At the same time, the transparent liquid storage bottle 33 has better aesthetics.

[0054] It should be understood that those of ordinary skill in the art can make improvements or transformations according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
