Description

Technical Field

[0001] This invention relates to the field of aromatherapy technology for use in homes, automobiles, offices, etc., and particularly to an air purifier. Background Technology

[0002] As people's living standards improve, in order to improve the air environment inside private cars or indoors, people usually place solid air fresheners, spray perfumes or aromatherapy essential oils in the car or indoors, and use negative ion purification methods to make the car or indoors fragrant and fresh, eliminate people's fatigue, and enliven the atmosphere inside the car or indoors.

[0003] Many existing air purification products integrate aromatherapy and negative ion purification functions. Whether for in-car or indoor use, these products typically use negative ion generators to produce negative ions through high-voltage ionization. However, this method produces a relatively small amount of negative ions, requiring a long and continuous production process to achieve air purification. This results in a long purification time and is primarily suitable for small spaces (such as car interiors or restrooms). For establishments like car washes, spray cans are typically used to spray aromatherapy products into the car interior to eliminate odors and freshen the air. However, this method has low and uneven coverage, failing to reach every corner, leading to poor post-wash fragrance. Furthermore, car washes have limited cleaning and care time for each vehicle, requiring rapid purification of the interior within a short period. Using a negative ion generator as a purification device is clearly ineffective, impacting vehicle care efficiency and purification results. Additionally, the aromatherapy and purification processes must be performed independently, requiring twice the time to complete both tasks, affecting user experience and efficiency. Summary of the Invention

[0011] Furthermore, the aromatherapy atomizing device includes a bottle body for containing a liquid fragrance matrix, a bottle cap located at the upper end of the bottle body and having an atomizing chamber inside, and an air pump communicating with the atomizing chamber. The atomizing chamber is provided with an atomizing core that communicates with the bottle body and atomizes the liquid inside the bottle. The upper end of the bottle cap is provided with a spray nozzle that communicates with the second pipe. The bottle cap is also provided with a mist outlet chamber that communicates with the atomizing core and the spray nozzle. The bottle cap is provided with an air hole that communicates with the mist outlet chamber and the bottle body.

[0012] Furthermore, the atomizing core includes an air guide and a cap that covers the outer periphery of the air guide and seals the upper end of the atomizing chamber from top to bottom. The upper end of the cap has an air outlet in the middle. The upper end of the air guide has a columnar part inserted into the air outlet in the middle. The outer diameter of the columnar part is smaller than the diameter of the air outlet, so as to form an air outlet gap between the columnar part and the air outlet. An air guide channel is formed between the cap and the air guide, connecting the air outlet gap and the atomizing chamber. A liquid spraying channel is provided vertically through the middle of the columnar part, connecting to the bottom of the air guide. The lower end of the cap has a liquid guide tube that communicates with the liquid spraying channel, and the lower end of the liquid guide tube extends to the inner bottom of the bottle body.

Secondly, the atomization generates a large quantity of fragrance and negative ions with high efficiency, achieving rapid purification and fragrance of the car interior within a limited time. Furthermore, fragrance dissemination and air purification can be performed simultaneously, reducing vehicle maintenance time and improving vehicle maintenance efficiency and user experience.

[0016] The system uses a container holding a liquid matrix in conjunction with an ultrasonic atomizer to generate negative ions.

Detailed Implementation

[0019] To better understand the technical content of the present invention, the present invention will be further introduced and described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the use of terms such as "first" and "second" in the text is for distinguishing different components, and does not represent the order of events, nor does it limit "first" and "second" to different types.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Example like Figures 1 to 11 As shown in the figure, an air purifier in this embodiment includes a housing 1 with an internal cavity 10, and a negative ion generator 2 and an aromatherapy atomizing device 3 disposed in the cavity 10.

[0022] The negative ion generating device 2 includes an atomizing device and a container 20 for holding a liquid matrix and supplying liquid to the atomizing device. The outlet of the atomizing device is connected to the outside of the box 1 through a first pipe 11 (such as connecting to the top or side of the box). That is, the liquid matrix in the container 20 flows to the atomizing device, and when the atomizing device is working, it atomizes the liquid matrix and outputs it to the external space through the first pipe 11 to achieve the purpose of air purification.

[0023] The aroma atomizing device 3 is used to atomize liquid aromatherapy, perfume and other fragrance substances, and the spray nozzle of the aroma atomizing device 3 is connected to the outside of the box 1 through the second pipe 12 (such as connected to the top or side of the box), that is, the aroma atomizing device 3 is used to atomize the fragrance substances and then deliver them into the external space.

[0024] In other words, the air purifier in this embodiment integrates an aromatherapy atomizer and a negative ion generator within its housing, enabling it to simultaneously diffuse fragrance and purify the air. Both functions deliver fragrance and negative ions into the space through atomization. Firstly, the atomization has a wide and uniform distribution range, covering any corner of the interior space, thus improving both purification and fragrance effects. Secondly, the atomization produces a large quantity of fragrance and negative ions efficiently, achieving rapid purification and fragrance of the car interior within a limited time. Furthermore, fragrance diffusion and air purification can be performed simultaneously, reducing vehicle maintenance time and improving vehicle maintenance efficiency and user experience.

[0025] In one embodiment, the liquid matrix in the container is a negative ion mixture of negative ion liquid and water; and the volume ratio of the negative ion liquid to water when mixed is (3-10):(90-97), that is, the negative ion liquid accounts for 3-10% of the total volume of the negative ion mixture; and negative ions are generated by atomizing the mixture of negative ion liquid and water.

[0026] The principle behind generating negative ions using a negative ion generator is as follows: Step 1: Dispersion of active substances Negative ion liquid is usually a liquid additive made by extracting tourmaline powder through nanotechnology and mixing it with plant ingredients. Tourmaline is a polar crystal with positive and negative charge centers on its surface, which can continuously generate microcurrents and negative electric fields. When it is mixed with water to form a negative ion mixture, these tiny tourmaline particles will be evenly dispersed in the water.

[0027] Step 2: Charge enrichment during atomization When the negative ion mixture is forcibly atomized into fine water droplets (typically 1-10 micrometers in diameter) through an atomizing device, a physical phenomenon called "fragmentation and charging" occurs. That is, at the moment the droplets break apart, the negative charge on the surface of the tourmaline preferentially adheres to the fine water droplets. Simultaneously, water molecules also ionize during high-speed friction and fragmentation (similar to the Renard effect), generating hydroxyl negative ions (OH-). - Ultimately, the aerosol particles formed by atomization not only contain moisture but also carry a high density of negative charges.

[0028] Step 3: Release and purification of ions in the air When negatively charged water mist particles enter the air, they are highly reactive; the negative charge (electrons) on the water mist particles easily detach and combine with oxygen molecules (O2) in the air to form negative ions (O2 ions). - Negatively charged particles actively adsorb positively charged dust, bacteria, formaldehyde, and other harmful substances in the air, causing them to clump and settle, thus achieving the purpose of dust removal, odor removal, and sterilization; and some negative ions combine with water molecules to form "hydrated negative ions" (such as O2). - (H2O)n), this form of negative ion has a longer lifespan and migrates farther in the air, making it more effective at adsorbing positively charged pollutants such as dust, bacteria, and formaldehyde.

[0029] In one embodiment, such as Figures 1 to 7 As shown, the atomizing device includes a hollow shell 21 and an ultrasonic atomizer 22 located at the bottom inner side of the shell 21. One side of the shell 21 is provided with an inlet pipe 23 that communicates with the container 20. That is, the negative ion liquid in the container 20 flows into the shell 21 through the inlet pipe 23 and is then atomized into water mist particles by the ultrasonic atomizer 22 at the bottom inner side of the shell 21. The upper end of the shell 21 is provided with an outlet 210 that communicates with the first pipe 11. That is, the atomized water mist particles are output to the outside through the first pipe 11.

[0030] Specifically, a base 24 is provided on one side of the shell 21, which is connected to the outer end of the liquid inlet pipe 23. The opening of the container 20 is inverted and can be detachably inserted into the base 24, so that the liquid matrix in the container 20 can be transported into the shell 21 under the action of gravity. The base 24 is provided with a slot 241 that is connected to the liquid inlet pipe 23 and has an upward opening. A piercing rod 242 is provided in the middle of the slot 241. The lower end of the container 20 is provided with a liquid outlet 201 that is inserted into the slot 241. The bottom of the liquid outlet 201 is provided with a liquid outlet hole 202 with a diameter larger than the piercing rod 242 for the piercing rod 242 to be inserted. That is, the combination of the container and the base adopts the water outlet method of combining a water dispenser and bottled water. Therefore, the shape of the container is preferably a barrel shape similar to that of bottled water.

[0031] Specifically, the atomizing device also includes a fan 25 located at the upper end of the housing 21 and blowing air into the housing 21. The fan's blowing action accelerates the outward flow of the atomized water mist particles, and allows the input air to combine with the atomized water mist particles to directly form negative ions before being output outward.

[0032] Specifically, the top of the housing 21 is also provided with an air guide shroud 26 covering the fan 25. The air guide shroud 26 is used to guide the air blown in by the fan 25 to the side wall away from the outlet. That is, the blown air flows down along the inner wall of the housing and then flows to the outlet on the other side, forming a back-and-forth flow effect, which prevents the atomized water mist particles from accumulating in the housing.

[0033] Specifically, in order to achieve the purpose of blowing air, the housing 1 is provided with several air inlets 13 that communicate with the outside, so that external air is drawn into the housing 1 through the air inlets 13.

[0034] In one embodiment, a groove 211 is provided on the inner bottom of the housing 21, the ultrasonic atomizer 22 is disposed in the groove 211, and the liquid inlet pipe 23 is located on the upper side of the groove 211; a drain port 212 is provided on one side of the housing 21, which is connected to the bottom of the groove 211, and the outer end of the drain port 212 extends outward from the housing 1 for discharging residual unused liquid. A sealing plug 213 is detachably provided on the outer end of the drain port 212 for sealing the drain port 212. That is, the sealing plug 213 can be removed when liquid needs to be drained, and the sealing plug 213 is used to seal when liquid does not need to be drained.

[0035] In one embodiment, a sensor 27 for detecting the liquid level inside the housing 21 is also provided on one side. The purpose is to identify and determine whether the liquid matrix in the container is used up, reminding the user to replenish or replace the container. Secondly, it is to prevent the ultrasonic atomizer from burning out due to low liquid level. In practice, the detection position of the sensor is usually set to be level with or slightly higher than the lowest point of the liquid inlet pipe. In this way, when the liquid level in the housing is lower than its detection position, it can be determined that no liquid continues to flow into the liquid inlet pipe, and thus it can be determined that the liquid matrix in the container is used up. The means of monitoring by sensor is a conventional technical means in the present, and will not be described in detail here.

[0036] In one embodiment, in order to facilitate the replenishment and replacement of containers, a door 14 for loading or unloading containers 20 is provided on one side of the box body 1. That is, after opening the door, the internal containers can be seen, and the containers can be taken out or reloaded.

[0037] In one embodiment, such as Figures 3 to 11As shown, the aromatherapy atomizing device 3 includes a bottle body 31 for containing liquid fragrance base (such as aromatherapy, perfume, etc.), a bottle cap 32 threaded to the upper end of the bottle body 31 and having an atomizing chamber 30 inside, and an air pump 33 communicating with the atomizing chamber 30. The atomizing chamber 30 is provided with an atomizing core that communicates with the bottle body 31 and atomizes the liquid inside the bottle. That is, the air pump 33 supplies high-pressure gas to the atomizing chamber 30, so that the liquid base inside the bottle is sprayed out from the atomizing core and broken and atomized by the high-pressure gas to form uniform and fine micro particles. The upper end of the bottle cap 32 is provided with a spray nozzle 321 communicating with the second pipe 12. The bottle cap 32 is also provided with a mist outlet 34 communicating with the atomizing core and the spray nozzle 321. The bottle cap 32 is also provided with an air hole 35 communicating with the mist outlet 34 and the bottle body 31.

[0038] Specifically, the atomizing chamber 30 is recessed in the middle of the bottom of the mist outlet chamber 34. The atomizing core includes an air guide 36 and a cover 37 that covers the outer periphery of the air guide 36 from top to bottom and seals the upper end of the atomizing chamber 30. That is, the cover 37 covers the upper end of the atomizing chamber. The upper end of the cover 37 has an air outlet 371 in the middle. The upper end of the air guide 36 has a columnar part 361 that is inserted into the air outlet 371. The outer diameter of the columnar part 361 is smaller than the diameter of the air outlet 371, so that an air outlet gap is formed between the columnar part 361 and the air outlet 371. An air guide channel 38 is formed between the cover 37 and the air guide 36, which connects the air outlet gap and the atomizing chamber 30. A liquid spraying channel 362 that connects to the bottom of the air guide 36 is provided vertically through the middle of the columnar part 361. The lower end of the cap 32 has a liquid spraying channel 362 that connects to the bottom of the air guide 36. The channel 362 is connected to the liquid guide tube 39, the lower end of which extends to the inner bottom of the bottle body 31. In this structure, after the air pump 33 inputs high-pressure gas into the atomizing chamber 30, the high-pressure gas flows along the air guide channel 38 and is finally ejected from the gas outlet gap. According to Bernoulli's principle, when high-pressure gas is ejected at high speed through a narrow nozzle or a specific channel, a local negative pressure (low-pressure area) will be formed in the surrounding area. Therefore, a negative pressure will be formed at the upper orifice of the liquid spraying channel 362, which will form a pressure difference with the pressure inside the liquid container. This will cause the liquid in the bottle to be ejected along the liquid guide tube 39 and the liquid spraying channel 362 and atomized by the high-pressure gas. Secondly, after the high-pressure gas flowing out through the gas outlet gap enters the mist outlet chamber, it can enter the bottle body along the air hole 35, further increasing the pressure inside the bottle and accelerating the ejection of liquid.

[0039] Specifically, the lower end of the air guide is sealed and inserted into the bottom of the atomizing chamber. A fixing post 322 is provided in the middle of the bottom of the bottle cap 32. A central hole 323 communicating with the liquid spraying channel 362 is provided through the center of the fixing post 322. The liquid guide tube 39 is fitted on the outside of the fixing post 322.

[0040] Specifically, the bottom of the mist outlet 34 is also recessed with a drain groove 341 surrounding the atomizing chamber 30, and the air hole 35 is located in the drain groove 341. During use, the aroma condensed in the mist outlet 34 flows back into the bottle through the drain groove and the air hole.

[0041] Specifically, the mist outlet chamber 34 is also provided with a shielding cover 342 covering the atomizing core and located on the outer periphery of the liquid leakage groove 341. A gap is formed between the outer periphery of the shielding cover 342 and the inner wall of the mist outlet chamber 34. Several mist outlet holes 343 communicating with the spray nozzle 321 are provided around the shielding cover 342. That is, the shielding cover is used to prevent the atomized fine particles from being sprayed directly into the spray nozzle. After being blocked by the shielding cover 342, the atomized fine particles can only flow outward along the mist outlet holes 343.

[0042] Specifically, a nozzle 324 is provided on one side of the bottle cap 32, which is connected to the atomizing chamber 30. The nozzle 324 is connected to the air pump 33 through the air pipe 320.

[0043] In another embodiment, the upper end of the bottle cap 32 is threadedly connected to a top cover 325, and a mist outlet 34 is formed between the top cover 325 and the bottle cap 32. The spray nozzle 321 is located at the upper end of the top cover 325.

[0044] In one embodiment, the air purifier further includes a circuit board 4 disposed inside the housing 1, a power socket 41 disposed on the front side of the housing 1, and several function switches 42 (including aromatherapy switch, purification switch, etc.). The circuit board 4 is electrically connected to the power socket 41, function switches 42, ultrasonic atomizer 22, fan 25, sensor 27 and air pump 33 respectively.

[0045] In other embodiments, the air purifier also includes a power supply 5 located inside the housing 1. The circuit board is connected to a power socket via the power supply, which converts AC mains power into low-voltage stable DC power, similar to a computer power supply.

[0046] In other embodiments, the power socket is a two-in-one socket with a power switch.

[0047] In other embodiments, a handle 203 is provided on one side of the container 20.

[0048] In other embodiments, a cover 15 may be detachably provided on the upper side of the housing 1. After opening the cover, the air pump, power supply and circuit board inside can be seen.

[0049] In other embodiments, the sensor works in conjunction with the circuit board, and when the sensor detects that the liquid level is lower than its detection level, the circuit board controls the ultrasonic atomizer to stop.

[0050] In other embodiments, an indicator light 16 connected to the circuit board can also be provided on the housing to work in conjunction with the sensor to remind the user.

[0051] In other embodiments, the housing, bottle cap, and air pump are all fixed to the box body by screws.

[0052] The technical solutions provided by the embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the embodiments above are only for helping to understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of the present invention.
