Description

Technical Field

[0001] This invention relates to the field of humidification technology, and more specifically to an atomizing device. Background Technology

[0002] A nebulizer is an instrument that converts liquids into micron-sized droplets. Nebulizers come in various types depending on their application, including humidifiers for air humidification, devices for treating upper respiratory tract infections, hairspray devices for hair styling, and other types. Currently, humidifiers with warm mist functions are widely used in homes, offices, and hospitals to increase humidity and achieve ideal temperature ranges in rooms.

[0003] Humidifiers with warm mist function typically include a liquid storage chamber, a heating wire for heating the liquid, and a power supply unit for powering the heating wire. A mist outlet is provided on the liquid storage chamber. The heating wire is located at the bottom of the liquid storage chamber to heat the liquid inside. Gas generated by liquid detection drifts out from the mist outlet. Since the entire liquid in the storage chamber needs to be heated each time humidification is needed, but the liquid in the storage chamber is not completely depleted each time it is used, the heating efficiency is low and the energy consumption is high. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and to provide an atomizing device.

[0007] Compared to existing technologies, the atomizing device of the present invention sprays water mist onto the heating plate through the atomizing component.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments 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. In the description of the present invention, unless otherwise stated, "a plurality of" means two or more, and "a number" means one or more. Furthermore, unless otherwise stated, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0021] Please see Figure 1 This is a schematic diagram of the structure of an atomizing device according to an embodiment of the present invention. The atomizing device includes: a housing 10 and a heating plate 20 and an atomizing component 30 disposed within the housing 10.

[0022] Please see Figure 2 and Figure 3 , Figure 2 This is a first cross-sectional view of an atomizing device according to an embodiment of the present invention. Figure 3This is a schematic diagram of the atomizing device according to an embodiment of the present invention with the housing portion concealed. The housing 10 is provided with a liquid storage chamber 11 and an evaporation chamber 12. The liquid storage chamber 11 can store water, aromatherapy liquid, etc. The evaporation chamber 12 is provided with a mist outlet channel 121 that connects to the outside of the housing 10. The heating plate 20 is disposed in the evaporation chamber 12 and has an evaporation surface 21. The atomizing component 30 is connected to the liquid storage chamber 11 and the evaporation chamber 12 respectively and is used to spray water mist toward the evaporation surface 21 of the heating plate 20. The heating plate 20 can heat the evaporation surface 21, thereby increasing the temperature of the evaporation surface 21. After the smaller droplets in the water mist adhere to the evaporation surface 21 of the heating plate 20, the droplets can be quickly heated and evaporated due to the high temperature of the evaporation surface 21 itself, thereby improving the efficiency of hot mist output and forming hot mist, which is water vapor. The hot mist diffuses to the outside of the housing 10 through the mist outlet channel 121. Since the heating plate 20 only heats the water mist droplets, it can heat only the amount of mist sprayed, so that the heating plate 20 does not need to heat the liquid in the storage chamber 11, reducing energy consumption and avoiding heating all the liquid in the storage chamber 11. This avoids the need to frequently replenish the liquid in the storage chamber 11 due to the reduction in the volume of the storage chamber 11 in order to speed up the mist output speed, as is done in the prior art.

[0023] Please see Figure 4 This is a second cross-sectional view of an atomizing device according to an embodiment of the present invention. In some optional embodiments, the atomizing device further includes a fan assembly 40, which is disposed inside the housing 10 and connected to the evaporation chamber 12 via an air pipe. The airflow generated by the fan assembly 40 enters the evaporation chamber 12 through the air pipe, and then drives the hot mist from the evaporation chamber 12 to be sprayed out of the housing 10 from the mist outlet channel 121, thereby increasing the diffusion range of the hot mist, improving the humidification and heating effect, and improving the user experience. In addition, in this embodiment, a check valve 42 is provided at one end of the air pipe 41 that extends into the evaporation chamber 12. The check valve 42 is rotatably connected to the air pipe 41. After the fan assembly 40 generates airflow, the airflow blows the check valve 42 up, thereby causing the check valve 42 to open the air pipe 41. When the fan assembly 40 stops running, the check valve 42 rotates to the position of closing the air pipe 41 by its own gravity, thereby preventing the steam in the evaporation chamber 12 from flowing back into the air inlet pipe 41.

[0024] Because water droplets contain some inorganic salts, after the droplets evaporate, inorganic salts are easily deposited on the evaporation surface 21 to form scale. Scale will affect heat transfer and reduce the heating effect of the evaporation surface 21. Therefore, in some optional embodiments, a scale storage chamber 13 is also provided inside the housing 10. The scale storage chamber 13 is located below the evaporation chamber 12 and is connected to the drain outlet 122 located at the bottom of the evaporation chamber 12. When the droplets do not evaporate, they can drive the inorganic salts on the evaporation surface 21 away from the evaporation surface 21, thereby avoiding the deposition of scale on the evaporation surface 21. The scale storage chamber 13 can collect liquid containing inorganic salts. After a certain amount has been collected, the user can remove the liquid in the scale storage chamber 13.

[0025] In some alternative embodiments, the evaporation surface 21 gradually slopes downwards towards the drain outlet 122, which facilitates the liquid on the evaporation surface 21 flowing under its own gravity to the lowest position of the evaporation surface 21 and then dripping to the bottom of the liquid storage chamber 12. The liquid then enters the scale storage chamber 13 from the drain outlet 122. In this embodiment, when it is necessary to remove inorganic salts from the evaporation surface 21, the spray volume of the atomizing component 30 is increased and the operation of the heating plate 20 is turned off, so that the mist droplets on the evaporation surface 21 accumulate and form larger droplets. The larger droplets can flow down the evaporation surface 21 and drip to the bottom of the evaporation chamber 12 and flow into the scale storage chamber 13, thereby achieving the effect of collecting inorganic salts. Preferably, the lowest position of the evaporation surface 21 is arranged directly above the drain outlet 122, which facilitates the liquid to drip directly from the evaporation surface 21 into the drain outlet 122.

[0026] To facilitate the removal of inorganic salts from the evaporation surface 21, the device enters descaling mode each time the user stops using the atomizing device. The heating plate 20 stops heating, while the atomizing component 30 operates at maximum power for a preset time. This causes the atomizing component 30 to spray a large amount of water mist into the evaporation chamber 12. Due to the high concentration of water mist in the evaporation chamber 12, larger droplets are formed on the evaporation surface 21. These larger droplets can flow down the evaporation surface 21, carrying away the inorganic salts on its surface. This prevents the deposition of inorganic salts on the evaporation surface 21 after each use of the atomizing device, reducing scale formation and keeping the evaporation surface 21 clean. This also avoids the need to remove the heating plate 20 after prolonged use due to scale buildup. Specifically, a timer is installed inside the housing 10. The timer is signal-connected to the heating plate 20 and the atomizing component 30. When the heating plate 20 stops operating, it sends a signal to the timer. The timer then counts the time and sends a descaling signal to the atomizing component 30. The atomizing component 30 operates at maximum power. After a preset time, the timer sends a stop signal to the atomizing component 30, causing it to stop operating. Furthermore, to prevent the water mist generated by the atomizing component 30 from leaving the mist outlet channel 121 after entering descaling mode, a solenoid valve can be installed inside the mist outlet channel 121. The solenoid valve is signal-connected to the timer. The timer counts the time and sends a descaling signal to the atomizing component 30 and the solenoid valve. The atomizing component 30 operates at maximum power, and the solenoid valve closes the mist outlet channel 121. This prevents the water mist generated by the atomizing component 30 from leaving the mist outlet channel 121, thus allowing larger droplets to condense better on the evaporation surface 21.

[0027] To facilitate the disposal of liquid containing a large amount of inorganic salts collected in the scale storage chamber 13, in some optional embodiments, a scale storage box 14 connected to the drain outlet 122 is movably disposed in the scale storage chamber 13. The scale storage box 14 can extend into or detach from the scale storage chamber 13 through an opening on one side of the scale storage chamber 13. Liquid flowing from the evaporation chamber 12 into the scale storage chamber 13 will be collected by the scale storage box 14. The scale storage box 14 adopts a drawer-type design, and the user can remove the scale storage box 14 from the opening on one side of the scale storage chamber 13 for easy disposal of waste liquid.

[0028] In some optional embodiments, the atomizing assembly 30 includes an atomizing seat 31, a pump body 32, and a flow sensor 33. The atomizing seat 31 is disposed within the evaporation chamber 12, with its spray nozzle facing the evaporation surface 21. The atomizing seat 31 is sequentially connected to the liquid storage chamber 11 via the pump body 32 and the flow sensor 33. The pump body 32 pumps the liquid in the liquid storage chamber 11 to the atomizing seat 31. The flow sensor 33 detects the amount of liquid entering the atomizing assembly 30. The liquid in the liquid storage chamber 11 sequentially passes through the flow sensor 33 and the pump body 32 before entering the atomizing seat 31. The atomizing seat 31 is provided with an atomizing plate that disperses the liquid using high-frequency electronic oscillation. Of course, the structure of the atomizing assembly 30 is not limited to this, and those skilled in the art can choose other suitable structures according to the teachings of this invention. The heating plate 20 is connected to the flow sensor 33. When the flow sensor 33 detects that no liquid is passing through, the flow sensor 33 sends a signal to the heating plate 20, and the heating plate 20 stops operating, thereby avoiding the heating plate 20 being in a dry-burning state when there is no liquid atomization and improving the safety of the device.

[0029] The structure of the flow sensor 33 can be selected according to actual needs. In this embodiment, the flow sensor 33 is a Hall flow sensor 33, the structure and principle of which are well known to those skilled in the art and will not be described in detail here.

[0030] In addition, in this embodiment, a one-way valve 112 is provided between the flow sensor 33 and the liquid storage chamber 11 to prevent liquid from flowing back into the liquid storage chamber 11.

[0031] Please see Figure 5 This is an exploded view of an atomizing device according to an embodiment of the present invention. In some optional embodiments, a top cover 15 is provided on the top of the housing 10, and a plurality of through slots 151 are arranged on the top cover 15. The port of the mist outlet channel 121 extends to the top of the housing 10 and communicates with the through slots 151. A water inlet 111 is provided on the top of the liquid storage chamber 11, and the water inlet 111 communicates with the through slots 151. The top cover 15 can provide a certain degree of protection for the mist outlet channel 121 and the water inlet 111, and facilitates the addition of water to the water inlet 111.

[0032] In some alternative embodiments, a drainage section 152 is formed on the top cover 15. The drainage section 152 gradually slopes downward in the direction near the water inlet 111, and the horizontal position of the drainage section 152 is lower than the horizontal position of the port of the mist outlet channel 121. A through groove 151 is provided on the drainage section 152, which extends from the port of the mist outlet channel 121 to the water inlet 111. Since hot mist droplets or moisture from the outside air may adhere to the top cover 15, large droplets may form on the top cover 15 and fall. These large droplets may drip into the mist outlet channel 121 and then onto the heating plate 20, affecting the evaporation of mist droplets by the heating plate 20. Through the design of the drainage section 152, the large droplets are guided to the water inlet 111 and fall into the liquid storage chamber 11, thereby recovering these large droplets, increasing the service life of the liquid in the liquid storage chamber 11, and thus preventing large droplets from entering the mist outlet channel 121.

[0033] To facilitate the installation of the top cover 15, in some optional embodiments, the top of the housing 10 is provided with a mounting groove 16, the port of the mist outlet channel 121 and the water inlet 111 are located in the mounting groove 16, the top cover 15 is inserted into the mounting groove 16, and the top of the top cover 15 is provided with a handle 153. By pulling up the top cover 15 with the handle 153, the water inlet 111 can be exposed for easy water replenishment. The handle 153 can be a U-shaped handle, a handle strap, or a handle groove, etc., and is not limited to this example.

[0034] In some optional embodiments, the bottom of the housing 10 is provided with several feet 17 and an anti-tipping switch 18 arranged on one side of the feet 17. The anti-tipping switch 18 is connected to the heating plate 20, the pump body 32 of the atomizing assembly 30, and the atomizing seat 31 of the atomizing assembly 30, respectively. The anti-tipping switch 18 is mainly used for anti-tipping function. When the housing 10 is tilted, the anti-tipping switch 18 is triggered and sends a tilting signal to the atomizing assembly 30 and the heating plate 20, causing the heating plate 20 and the atomizing assembly 30 to stop operating. The anti-tipping switch 18 can be a micro switch, etc., and is not limited to this example. The anti-tipping switch 18 is widely used in household appliances and electrical equipment. Its structure and principle are well known to those skilled in the art and will not be described in detail here.
