Description

Technical Field

[0001] This utility model relates to the field of medical and health care equipment technology, and in particular to a negative oxygen ion generating device for humidifying air. Background Technology

[0002] Negative oxygen ions generally refer to negative air ions, which are the collective term for negatively charged individual gas molecules and hydrogen ion clusters. In natural ecosystems, forests and wetlands are important sources of negative air oxygen ions, playing a regulatory role in air purification and urban microclimate. Their concentration level is one of the indicators for evaluating urban air quality.

[0003] Currently, most indoor negative ion generators are placed in corners. When in use, negative ions are too small to be observed with the naked eye or sensed by other means, making it impossible to determine whether the generator is working properly. Sometimes, it is also necessary to humidify the indoor air, but the water mist emitted by humidifiers can be clearly observed with the naked eye and can also serve as an indicator that the negative ion generator is working properly. Therefore, a negative ion generator that humidifies the air has emerged. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing negative ion generators, which cannot be used to observe whether they are working properly. This invention provides a negative ion generator that humidifies the air, producing both negative ions and water mist. The negative ions produced can improve indoor air quality, and the water mist can humidify the air. The water mist can also be used to indicate the generation of negative ions and the normal operation of the negative ion generator.

[0005] To achieve the above objectives, this utility model provides a negative oxygen ion generating device for air humidification, comprising a generating device body. The generating device body includes a generator installed at the top for generating negative oxygen ions and a water tank installed at the bottom for supplying water. The generator includes a lower housing shell located at the bottom. The lower housing shell has a middle plate at the top and a water inlet connected to the water tank at the bottom. The middle plate has a connection port for connecting compressed air on its side. An upper housing shell is located above the connection port, and the upper housing shell has an air outlet for outputting negative oxygen ions and water mist. Water from inside the water tank is input into the lower housing shell through the water inlet and is impacted by compressed air input from the connection port to generate negative oxygen ions and water mist. The negative oxygen ions and water mist move upward and are output outward together through the middle plate and the air outlet.

[0006] Preferably, the intermediate plate is provided with a first connecting hole that communicates with the interior of the lower housing. The negative oxygen ions and water mist reach the upper housing through the first connecting hole and are output through the air outlet. An input water pipe is installed in the middle of the intermediate plate. The input water pipe is connected to the water inlet and vertically inputs the water inside the water tank into the interior of the lower housing from the middle.

[0007] Preferably, the lower housing is further equipped with a U-shaped generating tank, which is installed at the lower part of the middle plate. A guide ring and a generating ring are sequentially installed on the upper part of the U-shaped generating tank from top to bottom. The input water pipe is inserted into the middle of the guide ring and is interconnected.

An output protrusion for water output is also provided at the end of the guide ring. A first through hole is provided in the middle of the generating ring, and the output protrusion is inserted into the first through hole, forming a high-speed airflow annular outlet between the output protrusion and the first through hole. The high-speed airflow annular outlet is connected to the second connecting hole, ejecting compressed air and generating negative pressure at the end of the output protrusion. Water flows vertically downwards and is cut and broken by the high-speed airflow annularly, forming negative oxygen ions and water mist.

[0008] Preferably, the bottom of the U-shaped generating barrel is equipped with an impact filter screen, which further splits and refines the water mist. The negative oxygen ions and water mist pass through the impact filter screen to reach the space between the lower housing and the U-shaped generating barrel, and move upwards to be output outwards through the first connecting hole of the intermediate plate and the air outlet of the upper housing.

[0009] Preferably, the output protrusion has a first annular inclined surface inside and a second annular inclined surface outside. The high-speed airflow annular outlet has a third annular inclined surface on the upper side and a fourth annular inclined surface on the lower side. The water inside the water tank is output through the inlet, the input water pipe, the guide ring and the output protrusion in sequence. It flows out faster on the first annular inclined surface. The second and third annular inclined surfaces guide the high-speed airflow to contract or compress, and cut the water molecules at the end of the output protrusion at an angle along the second and third annular inclined surfaces to generate negative oxygen ions and water mist.

[0010] Preferably, a cover plate is installed between the intermediate plate and the upper housing. The cover plate has a third connecting hole. The cover plate concentrates the negative oxygen ions and water mist passing through the intermediate plate, which then reach the upper housing through the third connecting hole and are output outward through the air outlet.

[0011] Preferably, the cover plate is provided with a fourth connecting hole, and the fourth connecting hole is provided with a fifth annular inclined surface. Some negative oxygen ions and water mist recondense into water and flow back into the lower housing through the fifth annular inclined surface and the fourth connecting hole. The upper housing has a housing cavity, and the upper end of the third connecting hole and the lower end of the air outlet both extend into the housing cavity. The third connecting hole is located on the side of the air outlet, and the upper end of the third connecting hole is higher than the lower end of the air outlet.

[0012] Preferably, the generator further includes a return water inlet installed at the bottom, one end of which is connected to the interior of the lower housing and the other end is connected to the water tank; the return water inlet returns the water inside the lower housing to the water tank; the return water inlet and the inlet are arranged horizontally side by side, and the ends of the return water inlet and the inlet are arranged horizontally and are horizontally inserted into the water tank.

[0013] Preferably, the generating device body further includes a connecting frame installed outside the water tank; the water tank is horizontally inserted into the connecting frame, the lower part of the connecting frame is provided with a fixing groove, and the fixing groove is provided with fixing bolts for fixing the connecting frame; the fixing groove is a vertical waist-shaped groove, which facilitates the adjustment of the vertical height of the connecting frame.

[0014] Preferably, the water tank includes an upper cover installed at the top and a lower bucket installed at the bottom. A handle groove is provided at the connection between the upper cover and the lower bucket to facilitate the removal of the water tank. The ends of the return water inlet and the inlet water inlet are provided with double sealing rings. The upper part of the upper cover is also provided with a water filling hole, which is covered with a plastic cap. One end of the water filling hole is hinged to the plastic cap, and the other end is provided with an opening groove for opening the plastic cap.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In use, the water inside the water tank is input into the lower housing through the inlet, and is impacted and broken by compressed air input from the connection port to generate negative oxygen ions and water mist. The negative oxygen ions and water mist move upward and are output outward together through the middle plate and the air outlet. Water mist is generated at the same time as negative oxygen ions and is also output outward together. Since the water mist and negative oxygen ions are generated together and mixed together, they cannot be separated. Thus, the water mist can be used to indicate the generation of negative oxygen ions and the normal operation of the negative oxygen ion generating device.

Detailed Implementation

[0028] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 7 This utility model provides a negative oxygen ion generating device for humidifying air.

[0030] like Figure 1 As shown, the generating device includes a generating device body 5. The generating device body 5 includes a generator 1 installed at the top for generating negative oxygen ions and a water tank 2 installed at the bottom for supplying water. The generator 1 and the water tank 2 are arranged vertically, and the water tank 2 is inserted into the lower part of the generator 1 and connected to the generator 1.

[0031] like Figure 2 As shown, the generator 1 includes a lower housing 13 located at the bottom, an intermediate plate 16 located in the middle, and an upper housing 11 located at the top. The intermediate plate 16 has a connection port 12 for connecting compressed air on its side. The negative oxygen ions and water mist are generated in the lower housing 13 and output in the upper housing 11.

[0032] like Figure 2 As shown, the generator 1 also includes a water inlet 15 and a water return outlet 61 located at the bottom; both the water inlet 15 and the water return outlet 61 are connected to the water tank 2; the water inlet 15 inputs water from inside the water tank 2 into the lower housing 13, and the water return outlet 61 returns water from inside the lower housing 13 back to the water tank 2; thereby realizing the recycling of water and ensuring that the water resources in the water tank 2 are fully utilized.

[0033] like Figure 2 As shown, the upper housing 11 is provided with an air outlet 14 for outputting negative oxygen ions and water mist. In use, water inside the water tank 2 is input into the lower housing 13 through the water inlet 15 and is impacted and broken by compressed air input from the connection port 12, thereby generating negative oxygen ions and water mist. The negative oxygen ions and water mist move upward and are output outward together through the intermediate plate 16 and the air outlet 14. Water mist is generated at the same time as negative oxygen ions and is also output outward together. Since the water mist and negative oxygen ions are generated together, they are mixed together and cannot be separated. Thus, the water mist can be used to indicate the generation of negative oxygen ions and the normal operation of the negative oxygen ion generating device.

[0034] like Figure 4As shown, the intermediate plate 16 is located between the upper housing 11 and the lower housing 13. The intermediate plate 16 is provided with a first connecting hole 161 that communicates with the interior of the lower housing 13, thereby enabling communication between the upper housing 11 and the lower housing 13. The negative oxygen ions and water mist are generated inside the lower housing 13, reach the upper housing 11 through the first connecting hole 161, and are output through the air outlet 14.

[0035] Furthermore, such as Figure 4 As shown, the middle plate 16 is equipped with an input water pipe 162, which is connected to the water inlet 15, and the water inside the water tank 2 is vertically input from the middle into the lower housing 13.

[0036] Furthermore, the middle plate 16 is provided with a connection port 12 on its side, through which the compressed air is input from the side into the lower housing 13.

[0037] like Figure 5 and Figure 6 As shown, a U-shaped generating tank 17 is also installed inside the lower housing 13. An impact occurs inside the U-shaped generating tank 17. The U-shaped generating tank 17 is installed at the lower part of the middle plate 16. A guide ring 18 and a generating ring 19 are installed sequentially from top to bottom on the upper part of the U-shaped generating tank 17. The input water pipe 162 is inserted into the middle of the guide ring 18 and is interconnected with it, so that water is output from the middle. The guide ring 18 has several second connecting holes 181 on its circumference that are connected to the connection port 12. The end of the guide ring 18 is also provided with an output protrusion 182 for outputting water.

[0038] like Figure 5 and Figure 6 As shown, the generating ring 19 has a first through hole 191 in the middle, and the output protrusion 182 is inserted into the first through hole 191. A high-speed airflow annular outlet 192 is formed between the output protrusion 182 and the first through hole 191. The high-speed airflow annular outlet 192 is connected to the second connecting hole 181, and compressed air is ejected. A negative pressure is generated at the end of the output protrusion 182, and water flows vertically downward. It is cut and broken by the high-speed airflow annularly to form negative oxygen ions and water mist.

[0039] The water inside the water tank 2 is output sequentially through the inlet 15, the input water pipe 162, the guide ring 18, and the output protrusion 182.

[0040] The compressed air is output sequentially through the connection port 12, the second connecting hole 181 and the high-speed airflow annular outlet 192, cutting, impacting and breaking down the water molecules in the middle, thereby forming negative oxygen ions and water mist.

[0041] like Figure 5and Figure 6 As shown, the bottom of the U-shaped generating barrel 17 is equipped with an impact filter 185. The impact filter 185 further splits and refines the water mist. The negative oxygen ions and water mist pass through the impact filter 185 to reach the space between the lower housing 13 and the U-shaped generating barrel 17, and move upwards to be output outwards through the first connecting hole 161 of the intermediate plate 16 and the air outlet 14 of the upper housing 11.

[0042] like Figure 5 and Figure 6 As shown, in order to make the impact more intense, thereby generating more negative oxygen ions and water mist, the output protrusion 182 has a first annular inclined surface 1821 inside and a second annular inclined surface 1822 on the outside. The water inside the water tank 2 is output through the inlet 15, the input water pipe 162, the guide ring 18 and the output protrusion 182 in sequence. The first annular inclined surface 1821 is used to accelerate the water molecules, so that they flow out faster.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the high-speed airflow annular outlet 192 has a third annular inclined surface 1921 on its upper side and a fourth annular inclined surface 1922 on its lower side. The second annular inclined surface 1922 and the third annular inclined surface 1921 guide the high-speed airflow to contract or compress, and along the second annular inclined surface 1922 and the third annular inclined surface 1921, the water molecules at the end of the output protrusion 182 are obliquely cut, impacted, and broken, thereby fully mixing the airflow and water molecules, producing more negative oxygen ions and water mist. This is more effective than the above-mentioned ordinary annular impact, producing more negative oxygen ions and water mist.

[0044] like Figure 5 As shown, a cover plate 50 is installed between the intermediate plate 16 and the upper housing 11. The cover plate 50 is provided with a third connecting hole 52. The cover plate 50 concentrates the negative oxygen ions and water mist passing through the intermediate plate 16. The concentrated negative oxygen ions and water mist reach the upper housing 11 through the third connecting hole 52 and are output outward together through the air outlet 14.

[0045] like Figure 5 As shown, the third connecting hole 52 has a large diameter, allowing more negative oxygen ions and water mist to reach the interior of the upper housing 11. A large number of negative oxygen ions and water mist are concentrated together, and some of them will recondense into water, while the rest will still be output outward through the air outlet 14.

[0046] like Figure 7As shown, in order to facilitate the return of the water molecules to the lower housing 13, the cover plate 50 is provided with a fourth connecting hole 53, and a fifth annular inclined surface 54 is provided on the fourth connecting hole 53. Water molecules flow back to the lower housing 13 through the fifth annular inclined surface 54 and the fourth connecting hole 53.

[0047] like Figure 5 As shown, in order to accommodate more negative oxygen ions and water mist, the upper housing 11 has a housing cavity 111. The housing cavity 111 has a large internal volume and is filled with negative oxygen ions and water mist. The upper end of the third connecting hole 52 and the lower end of the air outlet 14 extend into the housing cavity 111.

[0048] Furthermore, the third connecting hole 52 is located on the side of the air outlet 14, and the upper end of the third connecting hole 52 is higher than the lower end of the air outlet 14. Thus, the third connecting hole 52 and the air outlet 14 are not directly connected. Negative oxygen ions and water mist will first fill the receiving cavity 111, and then be output through the air outlet 14. The overall shape is S-shaped. The negative oxygen ions and water mist first reach the upper wall of the upper receiving shell 11, then move downward to the middle, and finally be output through the air outlet 14. In this way, water mist with larger molecular weight can be recycled, while water mist with smaller molecular weight can be output. The output water mist has a small molecular weight, which can humidify the air, but is not easy to make it damp.

[0049] like Figure 2 As shown, the generator 1 also includes a return water inlet 61 installed at the bottom. One end of the return water inlet 61 is connected to the inside of the lower housing 13, and the other end is connected to the water tank 2. The return water inlet 61 returns the water inside the lower housing 13 to the inside of the water tank 2. The return water inlet 61 and the inlet 15 are arranged horizontally side by side, and the ends of the return water inlet 61 and the inlet 15 are horizontally arranged and horizontally connected to the water tank 2.

[0050] like Figure 1 As shown, the generating device body 5 also includes a connecting frame 4 installed outside the water tank 2; the water tank 2 is horizontally inserted into the connecting frame 4, and the lower part of the connecting frame 4 is provided with a fixing groove 42, and the fixing groove 42 is provided with fixing bolts for fixing the connecting frame 4; the fixing bolts pass through the fixing groove 42 to fix the connecting frame 4 to the wall.

[0051] Furthermore, in order to facilitate the fixing of the connecting frame 4, the fixing groove 42 is a vertical waist-shaped groove, which facilitates the adjustment of the vertical height of the connecting frame 4.

[0052] like Figure 3As shown, the water tank 2 includes an upper cover 21 installed at the top and a lower bucket 22 installed at the bottom. A handle groove 23 is provided at the connection between the upper cover 21 and the lower bucket 22 to facilitate the removal of the water tank 2.

[0053] The upper part of the cover 21 is also provided with a water inlet 25, and a plastic cover 24 is provided on the water inlet 25. One end of the water inlet 25 is hinged to the plastic cover 24, and the other end is provided with an opening groove 26 for opening the plastic cover 24.

[0054] When water tank 2 needs to be added, use the handle groove 23 to pull water tank 2 horizontally open, separating it from generator 1 and also from connecting frame 4; use the opening groove 26 to open plastic cover 24, as... Figure 3 As shown, water is added through the water inlet 25.

[0055] like Figure 2 As shown, in order to facilitate the sealing between the water tank 2 and the generator 1, the ends of the return water port 61 and the inlet water port 15 are provided with double sealing rings 137; wherein, the return water port 61 directly returns water without the need for an additional connecting water pipe; the inlet water port 15 needs to be connected to an additional connecting water pipe in order to draw water from the bottom of the water tank 2 and send it into the generator 1.

[0056] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
