Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. In the description of the present invention, unless otherwise indicated, the meaning of "plurality" is 2 or more, and the meaning of "several" is 1 or more.

Referring to fig. 1, a schematic structural diagram of an atomization device according to an embodiment of the invention is shown, where the atomization device includes: a housing 10, and a heating plate 20 and an atomizing assembly 30 disposed within the housing 10.

Referring to fig. 2 and 3, fig. 2 is a first cross-sectional view of an atomizer according to an embodiment of the present invention, fig. 3 is a schematic structural view of the atomizer according to an embodiment of the present invention when a part of a housing is hidden, a liquid storage chamber 11 and an evaporation chamber 12 are provided in the housing 10, the liquid storage chamber 11 can store clean water, aromatherapy liquid, etc., the evaporation chamber 12 is provided with a mist outlet passage 121 communicated to the outside of the housing 10, a heating plate 20 is provided in the evaporation chamber 12 and has an evaporation surface 21, an atomizing assembly 30 is respectively communicated with the liquid storage chamber 11 and the evaporation chamber 12 for spraying water mist toward the evaporation surface 21 of the heating plate 20, the heating plate 20 can heat the evaporation surface 21, so that the temperature of the evaporation surface 21 is increased, and after droplets of smaller particles in the water mist are adhered to the evaporation surface 21 of the heating plate 20, the droplets can be rapidly heated and evaporated due to the high temperature of the evaporation surface 21 itself, so that the efficiency of the hot mist, i.e. the water mist, is formed, and the hot mist is diffused to the outside of the housing 10 through the mist outlet passage 121. Because the heating plate 20 only heats the mist drops of the water mist, the mist can be sprayed and heated, so that the heating plate 20 does not need to heat the liquid in the liquid storage cavity 11, the energy consumption is reduced, the heating of all the liquid in the liquid storage cavity 11 is avoided, and the liquid storage cavity 11 needs to be frequently supplemented because the volume of the liquid storage cavity 11 is reduced in order to accelerate the mist outlet speed in the prior art is avoided.

Referring to fig. 4, which is a second cross-sectional view of an atomization device according to an embodiment of the present invention, in some alternative embodiments, the atomization device further includes a fan assembly 40, the fan assembly 40 is disposed in the housing 10 and is communicated with the evaporation chamber 12 through an air pipe, an air flow generated by the fan assembly 40 enters the evaporation chamber 12 through the air pipe, and then drives hot mist of the evaporation chamber 12 to be ejected out of the housing 10 from the mist outlet channel 121, so as to improve a thermal mist diffusion range, improve effects of humidification and heating, and improve user experience. In addition, in the present embodiment, a check valve 42 is disposed at an end of the air pipe 41 extending into the evaporation chamber 12, the check valve 42 is rotatably connected to the air pipe 41, after the fan assembly 40 generates air flow, the air flow blows the check valve 42 up, so that the check valve 42 opens the air pipe 41, and when the fan assembly 40 stops operating, the check valve 42 rotates to a position closing the air pipe 41 by gravity, so as to prevent the vapor in the evaporation chamber 12 from flowing back into the air pipe 41.

Because some inorganic salt exists in the mist droplets of the water mist, inorganic deposition is easy to form scale on the evaporation surface 21 after the mist droplets are evaporated, the heat transfer is affected by the scale, and the heating effect of the evaporation surface 21 is reduced, therefore, in some alternative embodiments, a scale storage chamber 13 is further arranged in the shell 10, the scale storage chamber 13 is arranged below the liquid storage chamber 11 and is communicated with a water outlet 122 arranged at the bottom of the liquid storage chamber 11, when the mist droplets are not evaporated, the inorganic salt on the evaporation surface 21 can be driven to leave the evaporation surface 21, so that the deposition of the scale on the evaporation surface 21 is avoided, the scale storage chamber 13 can collect liquid containing the inorganic salt, and after the scale storage chamber 13 is collected to a certain degree, a user can clear the liquid in the scale storage chamber 13.

In some alternative embodiments, the evaporation surface 21 is gradually inclined downward in a direction approaching the drain opening 122, so that the liquid on the evaporation surface 21 can flow to the lowest position of the evaporation surface 21 by virtue of gravity and then drop to the bottom of the liquid storage cavity 12, and then the liquid can enter the scale storage chamber 13 from the drain opening 122. In the present embodiment, when the inorganic salt on the evaporation surface 21 needs to be carried away, the spray amount of the atomizing assembly 30 is increased, and the operation of the heating pan 20 is turned off, so that the mist droplets on the evaporation surface 21 are piled up and form larger droplets, and the larger droplets can flow down along the evaporation surface 21 and fall to the bottom of the evaporation chamber 12 and flow to the scale storage chamber 13, thereby achieving the effect of collecting the inorganic salt. Preferably, the lowest position of the evaporation surface 21 is disposed directly above the drain opening 122, thereby facilitating the liquid to drip directly from the evaporation surface 21 into the drain opening 122.

In order to be favorable for guiding inorganic salt to leave the evaporation surface 21, when the atomizing device is stopped to be used by a user each time, the atomizing device enters a descaling mode, the heating plate 20 stops heating, the atomizing assembly 30 runs in a preset time with maximum power, so that the atomizing assembly 30 sprays a large amount of water mist into the evaporation chamber 12, the evaporation surface 21 is favorable for condensing large liquid drops due to the large water mist concentration of the evaporation chamber 12, the large liquid drops can flow down the evaporation surface 21, the inorganic salt on the surface of the evaporation surface 21 is taken away, the inorganic salt deposited on the evaporation surface 21 can be avoided after the atomizing device is used each time, the formation of scale is reduced, the cleaning of the evaporation surface 21 is favorably maintained, and the heating plate 20 is prevented from being taken out to clean the scale due to the deposited scale after long-term use. Specifically, a timer is disposed in the housing 10 and is in signal connection with the heating plate 20 and the atomizing assembly 30, when the heating plate 20 stops running, the heating plate 20 sends a signal to the timer, the timer counts time and sends a descaling signal to the atomizing assembly 30, the atomizing assembly 30 runs at maximum power, and then after a preset time, the timer sends a stop signal to the atomizing assembly 30, so that the atomizing assembly 30 stops running. In addition, in order to avoid that the generated water mist of the atomizing assembly 30 leaves from the mist outlet channel 121 after entering the descaling mode, an electromagnetic valve can be arranged in the mist outlet channel 121 and is in signal connection with a timer, the timer counts time and sends descaling signals to the atomizing assembly 30 and the electromagnetic valve, the atomizing assembly 30 operates at maximum power, and the electromagnetic valve closes the mist outlet channel 121, so that the water mist generated by the atomizing assembly 30 cannot leave from the mist outlet channel 121, and larger liquid drops are better condensed on the evaporation surface 21.

In order to facilitate pouring of the liquid containing more inorganic salt collected in the scale storage chamber 13, in some alternative embodiments, the scale storage chamber 13 is movably provided with a scale storage box 14 communicated with the water outlet 122, the scale storage box 14 can extend into or separate from the scale storage chamber 13 from an opening arranged at one side of the scale storage chamber 13, the liquid flowing into the scale storage chamber 13 from the evaporation chamber 12 is collected by the scale storage box 14, the scale storage box 14 adopts a drawer type design, and a user can take the scale storage box 14 out from the opening at one side of the scale storage chamber 13, so that waste liquid can be conveniently poured.

Of course, the configuration of atomizing assembly 30 is not so limited and those skilled in the art will readily appreciate that other suitable configurations may be selected in accordance with the teachings of the present invention. The heating plate 20 is in signal connection with the flow sensor 33, when the flow sensor 33 detects that no liquid passes through, the flow sensor 33 sends a signal to the heating plate 20, and the heating plate 20 stops running, so that the heating plate 20 is prevented from being in a dry burning state when no liquid is atomized, and the safety of the device is improved.
