Description

Technical Field

[0001] The utility model relates to the technical field of atomization equipment, in particular to a dual-air-path atomization device. Background Art

[0002] Currently, to increase the diffusion rate of mist, a typical atomizer typically incorporates a fan within the atomization chamber, increasing the internal air pressure to force the mist out. When used as a disinfectant, a pipe typically connects the atomization chamber to the outside world, transporting the mist to a predetermined location. However, the mist flows slowly as it exits the pipe, lacking kinetic energy upon exiting the chamber, resulting in very low diffusion efficiency.

[0003] In addition, the atomization module used in the atomizer has a certain range of requirements for the liquid pressure. When the liquid level is too high, the atomization module cannot form mist or the amount of mist formed is too small, affecting the normal operation of the atomizer. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an atomizing device that can accelerate the rate at which mist is discharged from an exhaust pipe, thereby improving atomizing efficiency.

At the same time, the second fan drives the gas through the ventilation channel. After the gas passes through the ventilation channel and enters the confluence pipe, it drives the mist to be discharged outward along the confluence pipe at an accelerated speed, thereby achieving the purpose of rapid diffusion.

[0013] In some embodiments of the present invention, the control module includes a first floating switch and a second floating switch arranged inside the atomizing box for detecting the liquid level. The second floating switch is located above the first floating switch. When the liquid level drops to trigger the first floating switch, the water pump inputs the liquid in the liquid storage tank into the atomizing box until the liquid level rises to trigger the second floating switch, and the water pump stops working.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0026] In the description of this utility model, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0027] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0028] See also Figures 1 to 3 The utility model is a dual-air-path atomizing device, comprising: a body 100, an atomizing box 200 is provided on the body 100, an atomizing module 300 is provided in the atomizing box 200, the inner cavity of the atomizing box 200 is connected to the exhaust pipe 400, the atomizing box 200 is provided with a first fan 500 for inputting gas into its inner cavity, a confluence pipe 600 is sheathed on the outside of the output end of the exhaust pipe 400, a ventilation channel 700 is formed between the confluence pipe 600 and the outer wall of the exhaust pipe 400, the body 100 is provided with a second fan 800 for driving the gas to pass through the ventilation channel 700 to enter the confluence pipe 600, the gas passing through the ventilation channel 700 and the mist output from the exhaust pipe 400 are mixed in the confluence pipe 600 to accelerate the mist.

[0029] The dual-air-path atomizing device of the above structure utilizes a first blower 500 to input gas into the atomizing box 200, and utilizes the air pressure within the atomizing box 200 to drive the mist formed by the atomizing module 300 to be discharged from the exhaust pipe 400. At the same time, the second blower 800 drives the gas through the ventilation channel 700. After the gas passes through the ventilation channel 700 and enters the confluence pipe 600, it drives the mist to be discharged outward along the confluence pipe 600 at an accelerated speed, thereby achieving the purpose of rapid diffusion. It should be noted that the speed at which the second blower 800 drives the airflow through the ventilation channel 700 is faster than the speed of the airflow discharged from the exhaust pipe 400, forming a Venturi effect, which has an adsorption effect on the mist flowing along the confluence pipe 600. The airflow and mist are mixed and quickly output outward, thereby improving the efficiency of mist diffusion, which is particularly beneficial for the application of mist for sterilization and disinfection.

[0030] See also Figure 2 and Figure 3 In some embodiments of the present invention, the exhaust pipe 400 is vertically disposed at the upper end of the atomizer box 200, and the confluence duct 600 is arranged vertically. The central axis of the confluence duct 600 is collinear with the central axis of the exhaust pipe 400, so that the ventilation channel 700 is annular. It is understood that the mist contains a large amount of water vapor, which has a tendency to fall after being discharged from the body 100. Arranging the exhaust pipe 400 and confluence duct 600 vertically upward helps to increase the diffusion range of the mist. In addition, the annular shape of the ventilation channel 700 allows the airflow to form an annular negative pressure area on the inner wall of the confluence duct 600, which is conducive to better mixing and acceleration of the mist.

[0031] See also Figures 1 to 3 In some embodiments of the present invention, a gas bellows 810 is connected to the lower end of the converging duct 600. The inner cavity of the gas bellows 810 is connected to the converging duct 600 through the ventilation channel 700. The second fan 800 is disposed on the side wall of the gas bellows 810. It is understood that the air intake side of the second fan 800 is connected to the external environment, and the exhaust side of the second fan 800 inputs gas into the gas bellows 810. The air pressure in the gas bellows 810 then drives the gas through the ventilation channel 700 and into the converging duct 600, thereby improving air supply efficiency and helping to control noise.

[0032] See also Figure 2 and Figure 3 In some embodiments of the present invention, a trumpet-shaped air duct sleeve 820, wider at the bottom and narrower at the top, is provided on the upper end of the gas bellows 810. The upper end of the air duct sleeve 820 is connected to the lower end of the confluence duct 600. The exhaust pipe 400 passes through the middle of the air duct sleeve 820, with a gap between it and the inner circumferential wall of the air duct sleeve 820. It is understood that the gas within the gas bellows 810 flows upward from the lower end of the air duct sleeve 820 to the upper end of the air duct sleeve 820 to enter the ventilation channel 700. Because the air duct sleeve 820 is trumpet-shaped, wider at the bottom and narrower at the top, the radial gap between the lower end of the air duct sleeve 820 and the exhaust pipe 400 is larger than the radial gap between the upper end of the air duct sleeve 820 and the exhaust pipe 400, which accelerates the airflow, facilitates smooth gas flow, and reduces noise.

[0033] See also Figure 2 and Figure 3In some embodiments of the present invention, the atomization module 300 is arranged at the bottom of the atomization box 200, and the first fan 500 and the exhaust pipe 400 are respectively arranged on both sides of the top of the atomization box 200. The output end of the first fan 500 faces downward, and a baffle 110 is provided on the inner top wall of the atomization box 200, which is inclined downward toward the side of the first fan 500. The baffle 110 can guide the vertical downward airflow driven by the first fan 500 to the side wall of the atomization box 200. It should be noted that the downward blowing of the first fan 500 may stir up liquid waves, causing water droplets mixed with mist to enter the exhaust pipe 400, affecting the atomization quality. When the liquid is small, the downward blowing of the first fan 500 may also cause the liquid to flow to one side, exposing part of the atomization module 300, thereby causing dry burning. The setting of the above-mentioned baffle 110 can solve these problems. The vertical downward airflow driven by the first fan 500 can flow along the baffle 110 to the side wall of the atomization box 200, pass over the liquid surface, and then be discharged upward from the exhaust pipe 400 on the other side.

[0034] See also Figure 2 and Figure 3 In some embodiments of the present invention, in order to automatically replenish liquid to the atomizer box 200, the body 100 is provided with a liquid storage tank (not shown in the figure) on one side of the atomizer box 200. The liquid storage tank is connected to the atomizer box 200 via a water pump 900. The water pump 900 is electrically connected to a control module, and the control module drives the water pump 900 to input the liquid in the liquid storage tank into the atomizer box 200. In this embodiment, the upper part of the liquid storage tank is connected to a liquid injection pipe, and the side wall of the liquid storage tank has a transparent window extending in the height direction. The user can observe the liquid level in the liquid storage tank through the transparent window, so that the user can add liquid in time. A sensor for detecting the water level can also be provided in the liquid storage tank to remind the user to add or stop adding liquid through the sensor. In addition, since the liquid storage tank and the atomizer box 200 are provided independently, when the liquid in the liquid storage tank is insufficient, the user can directly add liquid to the liquid injection pipe without stopping the machine, which is convenient to use.

[0035] See also Figure 3In some embodiments of the present invention, the control module includes a first float switch 130 and a second float switch 140 provided inside the atomizing box 200 for detecting the liquid level. The second float switch 140 is located above the first float switch 130. When the liquid level drops to a level that triggers the first float switch 130, the water pump 900 pumps the liquid in the liquid storage tank into the atomizing box 200. When the liquid level rises to a level that triggers the second float switch 140, the water pump 900 stops working. Specifically, when the liquid level in the atomizing box 200 is too low, the first float switch 130 is triggered. At this time, the water pump 900 pumps the liquid in the liquid storage tank into the atomizing box 200, thereby realizing the function of automatically replenishing liquid. When the liquid level rises to a level that triggers the second float switch 140, the water pump 900 stops working, thereby avoiding the problem of the atomizing module 300 not being able to work or having low working efficiency due to excessive liquid added manually.

[0036] See also Figure 3 In some embodiments of the present invention, in order to prevent the atomizing module 300 from being damaged due to still working when the atomizing box 200 is dry, the control module further includes an anti-dry burning sensor 150 provided at the bottom wall of the atomizing box 200. The anti-dry burning sensor 150 is electrically connected to the atomizing module 300 so as to control the atomizing module 300 to stop working.

[0037] See also Figure 3 In some embodiments of the present invention, the atomizing module 300 is located in the middle of the bottom wall of the atomizing box 200, and the bottom wall of the atomizing box 200 is provided with a guide slope 210 that is inclined downward toward the atomizing module 300 at the edges of the atomizing module 300. It is understandable that when there is less liquid in the atomizing box 200, the liquid can still flow downward along the guide slope 210 to the atomizing module 300, which can also reduce liquid residue. In this embodiment, the outline shape of the atomizing module 300 is rectangular, and each of the four edges of the rectangle is connected to a guide slope 210.

[0038] In some embodiments of the present invention, the water pump 900 is a bidirectional water pump, and the control module can control the bidirectional water pump to pump the liquid in the atomizing box 200 back into the liquid storage tank. It should be noted that after the atomization operation is completed, the control module can control the bidirectional water pump to pump the liquid in the atomizing box 200 back into the liquid storage tank. After the liquid in the atomizing box 200 is drained, it is not easy to form residue and breed bacteria.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
