Referring to FIG. 2 , FIG. 2 is a schematic structural diagram of an atomizing device provided in some embodiments of the present application. For the convenience of description, the following embodiments are described with the atomization device of a specific embodiment provided in this application.

In some embodiments of the present application, the present application provides an atomizing device, comprising: an atomizing main body member 100 and an upper cover 200 , and the atomizing main body member 100 and the upper cover 200 are connected to form an integral atomizing device. Specifically, the upper cover 200 is provided with an air outlet hole 21 ; the atomizing body member 100 has a built-in gas conduction channel for gas transmission. When the atomizing main body 100 is connected with the upper cover 200 , the air outlet 21 is connected to the gas conduction channel, and finally the gas in the atomizing device is discharged to the outside of the atomizing device along the air outlet 21 .

Wherein, the atomizing main body member 100 includes a casing 11 and an atomizing core assembly 12 . The inside of the casing 11 is hollow to accommodate the atomizing core assembly 12 inside the casing 11 . Referring to FIG. 3 , FIG. 3 is a cross-sectional view of the atomizing device provided in some embodiments of the present application from a first perspective. The atomizing core assembly 12 includes an atomizing module 121 and a nozzle module 122 . The nozzle module 122 acquires the liquid for atomization (hereinafter referred to as liquid) in the liquid storage tank 13 , and sprays the acquired liquid toward the atomization module 121 . The atomization module 121 converts the mist droplets into a gaseous or aerosol state. In this solution, the nozzle module 122 can directly or indirectly extract the liquid to be atomized from the liquid storage tank 13 .

Specifically, referring to FIG. 6 , FIG. 6 is a cross-sectional view of the atomizing device provided in some embodiments of the present application from a second angle of view. The nozzle module 122 at least includes an atomizing nozzle 1221 , the atomizing nozzle 1221 can separate the liquid into small mist droplets, and the small mist droplets are dispersed in the air or attached to the atomizing surface of the atomizing module 121 . Since the atomizing core assembly 12 sprays the liquid toward the atomizing module 121 through the nozzle module 122, the common liquid collecting such as ceramic core and cotton core is omitted. In the prior art, in order to atomize the liquid stored on the liquid collector, the atomization module is often attached to or wrapped around the liquid collector, but in this solution, the contact between the liquid collector and the atomization module 121 is avoided, thereby avoiding It can effectively improve the user's experience by eliminating the sticky smell caused by the dry burning of the liquid collected by the atomizing module 121 .

Exemplarily, in order to prevent the small liquid droplets from spreading away from the atomization module 121, the atomization is insufficient. The atomizing nozzle 1221 sprays the liquid into the atomizing chamber 123, and the atomizing module 121 is attached to the inner wall of the atomizing chamber 123, so that the atomizing module 121 can spray the small liquid droplets in the atomizing chamber 123 from different positions. Atomization, thereby improving the atomization efficiency.

The atomization module 121 includes an infrared module, and the infrared module is arranged in the atomization cavity 123; small liquid droplets are sprayed into the atomization cavity 123 through the nozzle module 122, and the infrared wave radiation generated by the infrared module heats the small liquid droplets. droplets to convert small droplets into a gaseous or aerosol state. The infrared module includes an infrared radiation layer; specifically, an infrared radiation coating made of carbon material is coated on the inner wall of the atomization cavity 123 to form an infrared radiation layer, so that the infrared radiation layer is attached to the inner wall of the atomization cavity 123 . Conducting the infrared radiation layer through the electrodes enables the infrared waves generated on the infrared radiation layer to heat the space in the atomizing chamber 123, so that the temperature in the atomizing chamber 123 rises. At the same time, the infrared radiation layer also plays a role of heat preservation, preventing the heat from going out. Diffusion ensures the atomization temperature in the atomization chamber 123 . The atomizing nozzle 1221 is fixedly installed in the atomizing chamber 123, so that the liquid droplets sprayed by the atomizing nozzle 1221 are in the atomizing chamber 123 to avoid leakage.

In a specific embodiment, the nozzle module 122 further includes a catheter 1222 and a pump body (not shown). The liquid conduit 1222 can directly extend into the liquid storage tank 13, and the liquid in the liquid storage tank 13 is drawn through the pump body and pressed into the atomizing nozzle 1221 to spray and separate the liquid into small liquid droplets. However, in this specific embodiment, the length of time for the pump body to extract the liquid is difficult to control, and is also limited by the pressure in the liquid storage tank 13, making it difficult to precisely control the amount of liquid pumped by the pump body, especially when the pump body is pumping When the amount of liquid is excessive, and it is difficult for the atomization efficiency of the atomization module 121 to match the amount of liquid droplets generated, the non-atomized liquid droplets will be sucked out of the atomizing device along with the gas, which will affect the user experience. In this solution, the pump body is integrated in the atomizing nozzle 1221, so that the atomizing nozzle 1221 can draw the liquid from the liquid storage tank 13 via the liquid conduit 1222, and the pump body improves the hydraulic pressure in the atomizing nozzle 1221, so that the liquid can be removed from the liquid storage tank 13. The atomizing nozzle 1221 sprays out.

In this solution, the atomizing core assembly 12 further includes a dosing valve 125. The dosing valve 125 is located on the moving path for transferring the liquid between the nozzle module 122 and the liquid storage bin 13. The dosing valve 125 controls itself to open and close to send the liquid to the nozzle die. Group 122 provides fluid. Specifically, a quantitative valve 125 is provided at the bottom of the liquid storage tank 13 . The liquid in the liquid storage bin 13 flows out from the quantitative valve 125 under the action of its own gravity, and the liquid is supplied to the nozzle module 122 by controlling the quantitative valve 125, so that the quantitative valve 125 can be used to control the liquid supply amount for the nozzle module 122, thereby Precisely control the amount of liquid droplets sprayed by the nozzle module 122 in the atomizing chamber 123 .

In another preferred embodiment, in order to intuitively control the amount of liquid feeding each time, the nozzle module 122 indirectly extracts the liquid in the liquid storage bin 13 . The atomizing core assembly 12 further includes a buffer cavity 124 connecting the quantitative valve 125 and the nozzle module 122 . The buffer cavity 124 is located on the moving path of the liquid transmission between the quantitative valve 125 and the nozzle module 122 , so that the liquid in the liquid storage tank 13 flows into the buffer cavity 124 first, and the nozzle module 122 extracts the liquid in the buffer cavity 124 . Specifically, the storage chamber 124 is provided below the liquid storage tank 13 , and the liquid in the liquid storage tank 13 flows into the storage chamber 124 under the force of its own weight. The amount of liquid flowing into the buffer chamber 124 is controlled by controlling the opening and closing of the quantitative valve 125 . The amount of liquid flowing into the buffer chamber 124 can be read intuitively.

Exemplarily, one end of the catheter 1222 is connected to the atomizing nozzle 1221 , and the other end extends into the buffer chamber 124 from the bottom of the buffer chamber 124 . The liquid inlet on the other end of the catheter 1222 extending into the buffer chamber 124 is located not higher than the bottom surface of the buffer chamber 124, so that the liquid in the buffer chamber 124 can flow into the atomizing nozzle 1221 completely through the catheter 1222 and be sprayed out. In order to precisely control the liquid feeding amount at each atomizing nozzle 1221 and avoid residual liquid in the buffer chamber 124, when the quantitative valve 125 sends liquid to the buffer chamber 124 again, it will affect the accuracy of the next liquid feeding amount.

Preferably, a liquid level sensor 1223 is connected to one end of the catheter 1222 extending into the buffer cavity 124 , and the liquid level sensor 1223 is located in the buffer cavity 124 . The liquid level in the buffer chamber 124 is detected according to the liquid level sensor 1223 , so as to monitor the amount of liquid in the buffer chamber 124 . The liquid level sensor 1223 is used to accurately detect the liquid in the buffer chamber 124 , so that the user can intuitively obtain the amount of liquid sprayed by the nozzle module 122 each time.

In some embodiments of the present application, as shown in FIG. 3 , the hollow space in the housing 11 is partitioned to form an atomization chamber 123 , a buffer chamber 124 and a liquid storage chamber 13 . Specifically, the liquid storage tank 13 , the buffer chamber 124 , and the atomization chamber 123 are sequentially arranged from top to bottom along the vertical direction. It is convenient for the liquid to be finally introduced downward into the atomizing cavity 123 under the action of its own weight.

It should be pointed out that the atomizing cavity 123 , the buffer cavity 124 and the liquid storage tank 13 are not limited to be formed by partitioning the hollow space in the housing 11 . Taking the liquid storage tank 13 as an example, the liquid storage tank 13 may also be formed together with the upper cover 200 through the casing 11 or independently formed by the upper cover 200 .

In this solution, the atomization chamber 123 is connected to an air flow pipe 14 , and the air flow pipe 14 is connected to the air outlet 21 of the upper cover 200 , so as to transport the atomized gas in the atomization chamber 123 to the air outlet 21 . A return chamber 15 is also provided in the casing 11 , and the return chamber 15 is located above the liquid storage chamber 13 . The atomization chamber 123 is communicated with the return chamber 15 through the air flow pipe 14 . Referring to FIG. 5 , FIG. 5 is a schematic three-dimensional structural diagram of an atomizing main body member in an atomizing device provided in some embodiments of the present application. An exhaust port 112 is opened on the upper surface 111 of the housing 11 , and the exhaust port 112 communicates with the return chamber 15 . The atomized gas in the atomization chamber 123 is sent to the return chamber 15 through the air flow pipe 14 , and then the gas flows into the air outlet 21 through the exhaust port 112 on the return chamber 15 . A reflux bin 15 is arranged between the air outlet 21 and the gas flow pipe 14, so that the gas or liquid droplets remaining in the atomizing device can be condensed and gathered and returned to the atomizing chamber 123 to perform secondary atomization of the condensed liquid, so that the increase profit.

Exemplarily, as shown in FIG. 6 , and referring to FIGS. 7 and 8 , FIG. 7 is a partial enlarged schematic view of B in FIG. 6 , and FIG. Cutaway. The bottom surface of the return chamber 15 is inclined. The bottom surface of the return chamber 15 includes an inclined surface 151, and the inclined surface 151 is inclined with respect to the horizontal plane. Specifically, the number of inclined planes 151 is two, and the inclined planes 151 are symmetrically arranged with the airflow duct 14 as the center, so that the airflow duct 14 is located at the lowest point in the vertical direction of the bottom surface of the reflux bin 15, and the condensate will follow the inclined plane 151. The airflow duct 14, and finally the condensate falls back into the atomization chamber 123 along the airflow duct 14. Referring further to FIG. 9 , FIG. 9 is a schematic diagram of the airflow in the atomizing device provided in some embodiments of the present application. The return chamber 15 is formed by combining the hollow part at the top of the casing 11 with the upper cover 200 . The upper cover 200 is provided with an air guide groove 22 , and the air guide groove 22 is disposed corresponding to the exhaust port 112 . The gas is discharged from the exhaust port 112 and then guided to the air outlet 21 along the air guide groove 22 . A liquid storage tank 152 that is recessed downward is provided at the intersection of the two inclined surfaces 151. The air port of the airflow duct 14 is opened at the bottom of the liquid storage tank 152. The condensate on the inclined surface 151 will converge to the liquid storage tank 152. 152 flows into the airflow duct 14 .

Further, a protruding stopper is arranged in the air guide groove 22 . When the gas or aerosol passes through the stopper, the gas will continue to flow outward beyond the stopper, and the liquid entrained in the gas or aerosol will adhere to the stopper to restrict the liquid from being discharged from the atomizing device.

Exemplarily, the air guide groove 22 includes a liquid guide surface 221 and a stop surface 222 serving as a stopper. The exhaust port 112 is disposed corresponding to the liquid conducting surface 221 , and the stop surface 222 is located on the flow path of the gas flowing to the air outlet hole 21 . The liquid conducting surface 221 and the stop surface 222 form an inner notch. Since the gas in the exhaust port 112 is discharged toward the liquid guide surface 221, the liquid droplets entrained by the gas or the condensed liquid condensed in the cold will adhere to the liquid guide surface 221, and the gas can easily pass over the liquid guide surface 221 and the stop surface due to its light weight. 222 to form the inner recess. The liquid adhering to the liquid conducting surface 221 will be blocked by the blocking surface 222 and it is difficult to enter the air outlet hole 21 . The liquid guide surface 221 is an inclined surface, and the liquid guide surface 221 gradually approaches the axis of the air outlet 21 along the airflow direction, and the liquid adhering to the liquid guide surface 221 converges to form a large droplet which is subject to its own larger self-weight along the inclined liquid guide surface. 221 slides down and finally returns to the return chamber 15 from the exhaust port 112 .

Further, as shown in FIG. 3 , and referring to FIG. 4 , FIG. 4 is a partial enlarged schematic diagram of the position A in FIG. 3 . The airflow duct 14 includes a first air passage 141 and a second air passage 142 , and the first air passage 141 and the second air passage 142 will be connected by a transition portion 143 . The first air passage 141 is connected to the return chamber 15 , and the second air passage 142 is connected to the atomization chamber 123 . In addition, the cross-sectional area of the first air passage 141 is larger than that of the second air passage 142, and the cross-sectional area of the second air passage 142 is small, so that the flow speed of the gas flowing in the second air passage 142 is faster, thereby facilitating the quickening of the mist. The gas in the chemical chamber 123 is carried out. The transition portion 143 is provided with a chamfered angle and facilitates the condensate to flow back smoothly from the first air passage 141 to the second air passage 142 .

In some embodiments of the present application, the casing 11 is provided with a buffer bin 16 . The atomization chamber 123 is located in the buffer chamber 16 . Specifically, a small space is divided into the buffer bin 16 as the atomization chamber 123 . In order to keep the temperature of the atomization chamber 123 at a higher temperature, so as to improve the atomization efficiency. In this solution, reducing the volume of the atomization chamber 123 is beneficial to keep the temperature in the atomization chamber 123 stable; and it is also convenient to increase the temperature in the atomization chamber 123 faster to reach the temperature required for atomization.

On the other hand, as shown in FIGS. 8 and 9 , the housing 11 is provided with an air inlet 113 , and the air inlet 113 is connected to the buffer bin 16 , so that the outside air can enter the buffer bin 16 from the air inlet 113 to compensate the gas in the buffer bin 16 . Because in the atomization process, the external gas needs to be mixed with the atomized gas before it can be sent out from the air outlet 21 . The gas for mixing comes from the buffer chamber 16 , and the gas in the buffer chamber 16 can enter the atomization chamber 123 from the connection gap of the atomization chamber 123 . The consumed gas in the buffer bin 16 is filled in from the outside atmosphere through the air inlet 113 . In addition, the outer side wall of the atomizing chamber 123 extends outward to form a fixing rod, and the fixing rod is inserted into the air inlet 113 to fix the atomizing chamber 123 .

Further, a fog volume detection module 126 is also arranged in the atomization chamber 123, and the fog volume detection module 126 obtains the aerosol volume signal; the fog volume detection module 126 is used to monitor the liquid in the atomization chamber 123 according to the aerosol volume signal. The mist volume detection module 126 is used to intuitively understand the aerosol volume of the liquid in the atomization chamber 123, so as to facilitate the subsequent steps of the aerosol volume signal control.

The present invention also provides a liquid atomization method, which is suitable for the atomization device in the above embodiment. Referring to FIG. 1 , FIG. 1 is a schematic diagram of an atomization method provided in some embodiments of the present application.

When the quantitative valve 125 is opened to supply liquid into the buffer chamber 124, the liquid level in the buffer chamber 124 rises to the level where the liquid level sensor 1223 detects the high level liquid level signal, and the liquid level sensor 1223 transmits the high level liquid level signal to the quantitative valve 125, Nozzle module 122 and atomization module 121 . The nozzle module 122 extracts the liquid in the buffer cavity 124 so that the liquid level in the buffer cavity 124 drops until the liquid level sensor 1223 detects the low level liquid level signal, and the liquid level sensor 1223 sends the low level liquid level signal to the nozzle module 122 and the liquid level sensor 1223 respectively. The atomizing module 121 makes the nozzle module 122 and the atomizing module 121 stop working according to the low-level liquid level signal.
