Description

Atomizing module capable of being installed and used at multiple angles and portable micropore atomizing device

Technical Field

The invention relates to the field of atomization equipment, in particular to an atomization module capable of being installed or used at multiple angles, and further relates to a micropore atomization device using the atomization module.

Background

At present, the micropore atomization device on the market mainly conducts liquid to the surface of the micropore atomization sheet through a water absorption cotton core, for example, Chinese utility model patents with publication numbers of CN208393047U, CN209655495U and CN 207190736U. However, the absorbent cotton core is easy to deteriorate and smell after being used for a period of time, and the liquid-guiding capacity of the absorbent cotton core is reduced along with the increase of the using time, so that a user needs to replace the absorbent cotton core regularly, which brings inconvenience to the use.

In order to solve the problems caused by the absorbent cotton core, the prior art discloses an atomizing device for pumping water by a pump, for example, chinese patent publication No. CN105764616A, which discloses an atomizing device comprising: a pump; a reservoir in fluid communication with the pump; an atomizing device in flow communication with the pump and the reservoir; wherein the atomizing device comprises a housing having at least a front wall, a rear wall and an enclosed interior space defined by the front and rear walls, the front wall having a through hole; an ultrasonic atomizer disposed in said interior space proximate to the through-hole; a flow-through supply compartment extending through the housing and into the interior space, the flow-through supply compartment configured to deliver pumped liquid to the ultrasonic atomizer; an overflow return compartment extends through the hood and into the interior space, the overflow compartment being configured to return liquid in the interior space to the container. The housing further having an inner weir wall defining a fluid receiving space and a fluid overflow space in the interior space of the housing; the fluid supply compartment is configured to deliver fluid into the fluid receiving space, and the overflow return compartment is configured to return fluid from the overflow space to the container.

Disclosure of Invention

The chinese patent publication CN105764616A discloses that the height of the weir wall is used to adjust the maximum liquid level in the fluid receiving space, so as to ensure that enough liquid for the ultrasonic atomizer to atomize is stored in the fluid receiving space under the condition of sufficient water pumping amount, and to discharge the excessive liquid through the fluid overflow space, however, the spraying device has a single use angle, which is inconvenient for a user to install at different angles of the spraying device or change the use angle at any time, because if the spraying device is inclined or turned upside down, the weir wall may be inclined or inverted, and when the amount of the liquid in the fluid receiving space is not higher than a predetermined maximum amount, the liquid may flow along the weir wall to the fluid overflow space without being completely limited by the height of the weir wall, thereby affecting the normal spraying of the ultrasonic atomizer.

In view of the above, in order to overcome the above technical problems, the present invention provides an atomization module capable of being installed or used at multiple angles, which includes a first outer housing and a microporous atomization sheet, wherein the microporous atomization sheet is located inside the first outer housing, and a mist outlet for discharging atomized vapor atomized by the microporous atomization sheet is arranged on the first outer housing; the liquid-liquid separation device is characterized by further comprising a platform piece arranged on the inner side of the first outer shell, wherein a central cavity and side cavities which are arranged at intervals are arranged in the platform piece, so that a separation wall is arranged between the side cavities and the central cavity, the side cavities and the central cavity are provided with opening parts, the opening directions of the side cavities and the central cavity are the same, and a liquid inlet pipe orifice communicated with the central cavity and used for providing liquid for the central cavity and a return pipe orifice communicated with the side cavities and used for releasing the liquid in the side cavities are also respectively arranged in the platform piece; the micropore atomization sheet covers the open parts of the central cavity and the side cavity, and a first sealing ring is arranged between the micropore atomization sheet and the platform piece, and the first sealing ring surrounds the open parts of the central cavity and the side cavity so that liquid in the central cavity and the side cavity cannot leak out from a gap between the micropore atomization sheet and the platform piece; an overflow gap is maintained between the microporous atomization sheet and the partition wall, the overflow gap being arranged to function as an overflow that not only overflows excess liquid from the central cavity into the side cavities, but also is adapted in height to allow overflow liquid to contact the microporous atomization sheet when the microporous atomization sheet is positioned above the liquid within the central cavity so that the microporous atomization sheet remains atomized.

Wherein, multi-angle installation or use, the definition be the micropore atomizing piece of atomizing module can be installed or use on atomizing device with the mode that is multi-angle, for example micropore atomizing piece can install the top of atomizing device with the direction spraying upwards or install the lateral part at atomizing device and spray towards the side direction etc. can also understand as can alternate at will when atomizing device work thereby letting micropore atomizing piece be different angle directions but can not influence the normal work of micropore atomizing piece.

Wherein the first housing body is adapted to receive or conceal the means for mounting the microporous atomizing sheet and platform member, whereby the microporous atomizing sheet and platform member are located on the inside of the first housing body, the feature essentially defining a definition of a relative orientation therebetween, which in turn is understood to mean that the location at which the microporous atomizing sheet and platform member is mounted is defined as the location on the inside of the first housing body.

Wherein, micropore atomization piece has the micropore, micropore atomization piece is in the following the control circuit board's drive under high-frequency vibration, make the inboard liquid of micropore atomization piece is high-frequency vibration's drive down via micropore in the micropore atomization piece sprays to the outside and goes out, and liquid is compelled to pass micropore in the micropore atomization piece can form the droplet of small particle size, and then is in the outside of micropore atomization piece forms atomization effect.

The atomizing device comprises a first shell body, a micropore atomizing sheet, a second shell body, a first atomizing channel and a second atomizing channel, wherein the fog outlet is formed in the first shell body, the micropore atomizing sheet can be tiled below the fog outlet, atomized steam of the micropore atomizing sheet is directly sprayed into an external space from the fog outlet, or the micropore atomizing sheet is arranged at other proper positions on the inner side of the first shell body, and the atomized steam sprayed by the micropore atomizing sheet reaches the fog outlet through a fog outlet channel and is sprayed into the external space.

Wherein the micropore atomization sheet covers the open parts of the central cavity and the side cavity, and a first sealing ring is arranged between the micropore atomization sheet and the platform piece, the first sealing ring surrounds the open parts of the central cavity and the side cavities, so that the liquid in the central cavity and the side cavities can not leak out from the gap between the micropore atomization sheet and the platform piece, the feature mainly defines the relative position relationship and connection relationship among the micropore atomization sheet, the first sealing ring and the platform part, the micropore atomization sheet is connected with the platform piece in a sealing way through the first sealing ring, the micropore atomization sheet also covers the open parts of the central cavity and the side cavities, therefore, the micropore atomization sheet, the first sealing ring and the platform piece form an atomization module which can contain liquid and can be installed or used at various angles.

Wherein an overflow gap is maintained between the microporous atomizing sheet and the partition wall, the overflow gap being arranged to overflow excess liquid in the central cavity into the side cavities, and when the microporous atomizing sheet is positioned above the liquid in the central cavity, the overflow gap being of a height suitable to allow overflow liquid to contact the microporous atomizing sheet to keep the microporous atomizing sheet atomized. This feature mainly defines:

first, the location and configuration of the relief gap arrangement is such as to achieve its functional role. Wherein the overflow gap has firstly an overflow channel structure capable of overflowing so as to overflow excess liquid in the central cavity (excess liquid = liquid entering from the inlet spout — liquid that has been atomized by the microporous atomizing sheet) into the side cavities.

Secondly, when the micropore atomization sheet is placed above the liquid in the central cavity, the micropore atomization sheet is in a horizontal state at this moment, the liquid level of the liquid in the central cavity is also in a horizontal state, the liquid in the central cavity needs to overflow through the top wall surface of the partition wall, at this moment, the top wall surface of the partition wall defines not only the lowest position of overflow, but also defines that the liquid level of the liquid in the central cavity is definitely not lower than the top wall surface of the partition wall, otherwise, the overflow cannot be formed, and the overflow liquid level defined by the top wall surface of the partition wall is higher than the top wall surface of the partition wall. To this end, the height of the overflow gap is adapted to allow overflow liquid to contact the microporous atomization sheet so as to allow the microporous atomization sheet to keep atomizing, and the feature first includes that the height distance between the microporous atomization sheet and the partition wall is set to allow the liquid surface of the liquid to contact the microporous atomization sheet, and the distance can be very small, and the size of the distance is enough to allow the overflow liquid level defined by the top wall surface of the partition wall to be higher than the top wall surface of the partition wall so that the liquid can contact the microporous atomization sheet when the liquid flows over the top wall surface of the partition wall; secondly, since the liquid inside the central cavity can contact the microporous atomization sheet, this feature also includes that the liquid inside the central cavity is actually full, so that when the microporous atomization sheet is swung (mounted or moved) to a position above the liquid inside the central cavity, the microporous atomization sheet can maintain atomization. For example, the overflow gap is of a flat structure, a small gap is formed between the microporous atomization sheet and the partition wall in the height direction (at this time, a structure that multiple points contact is formed between the microporous atomization sheet and the top wall surface of the partition wall is not excluded), but a relatively wide overflow width is formed in the horizontal direction, so that the overflow gap can overflow while an overflow liquid level contacts the microporous atomization sheet, and liquid in the central cavity is always kept in a filling state. The central cavity is filled with liquid but not necessarily with a high intra-cavity pressure while the liquid in the central cavity remains filled.

When the microporous atomization sheet is placed (mounted or swung) at an angle that intersects the liquid in the central chamber, the overflow volume does not substantially change because the overflow gap does not change. For this purpose, the liquid in the central chamber also remains filled when the atomizer module is in operation.

From another perspective, of course, the liquid level inside the central cavity is brought into contact with the microporous atomization sheet and is also related to the pressure or flow rate of the liquid entering the central cavity from the liquid inlet nozzle of the central cavity, wherein the greater the pressure or flow rate of the liquid entering from the liquid inlet nozzle is, the easier the liquid level inside the central cavity is brought into contact with the microporous atomization sheet, but this aspect is not a critical consideration in the patent design, and we can fully assume that in a specific embodiment, on the basis of assuming that the pressure or flow rate parameter of the liquid entering from the liquid inlet nozzle is already selected, the arrangement structure of the overflow gap is mainly considered, and therefore, the arrangement structure of the overflow gap itself is the most basic structure.

The overflow gap can be a gap formed by suspending the micropore atomization sheet and the top wall surface of the partition wall, or can be a circulation groove directly arranged on the partition wall at intervals, and when the micropore atomization sheet is tightly attached to the top wall surface of the partition wall, the micropore atomization sheet covers the circulation groove and is combined to form a liquid circulation channel.

Wherein the microporous atomizing sheet is placed at a position above the liquid in the central cavity at an installation angle position or a use angle position using the microporous atomizing sheet, and since the liquid surface is always in a horizontal direction in a free state, the microporous atomizing sheet is placed at a position above the liquid in the central cavity, and in fact, the microporous atomizing sheet is also placed at a position in the horizontal direction and above the liquid in the central cavity at the time, and is also an extreme position at which the microporous atomizing sheet is placed, because the microporous atomizing sheet is more or less easily contacted with the liquid at other angle positions, and when the microporous atomizing sheet is placed at a position above the liquid in the central cavity, the microporous atomizing sheet can also be contacted with the water level through the structure of the overflow gap, other angular positions are more accessible to the water level.

According to the scheme, liquid enters the central cavity from the liquid inlet pipe orifice of the central cavity, overflows to the side cavity through the overflow gap and flows out through the backflow pipe orifice. When the micropore atomization sheet is placed at a position above the liquid in the central cavity, the overflow liquid level defined by the top wall surface of the partition wall can contact the micropore atomization sheet, so that the liquid can be atomized at the angle position. Compared with the prior art, the atomizing module of the invention has the advantages that firstly, the micropore atomizing sheet, the first sealing ring and the platform piece form the atomizing module which can contain liquid and overflow liquid and can be installed or used at various angles, so that the use flexibility of the atomizing module is greatly improved, and the atomizing module can be freely used by a user without being limited by angles particularly when being used in a handheld atomizing device; secondly, the overflow gap is directly formed between the microporous atomization sheet and the partition wall, so that the structure of the atomization module is greatly simplified, and the encumbrance is reduced; thirdly, this is simple the overflow clearance structure itself not only can overflow, moreover the height in overflow clearance is suitable for and lets overflow liquid can contact thereby micropore atomizing piece can let micropore atomizing piece keeps atomizing, lets liquid can remain at filling state throughout in the central cavity, and that is based on this state can let micropore atomizing piece is put to being located at any time the liquid level also can reach when the top position of the inside liquid of central cavity thereby the micropore atomizing piece can let micropore atomizing piece keeps at atomizing state.

In a further technical solution, the side cavity surrounds the central cavity to form an annular structure. At the moment, the partition wall is of an annular structure matched with the partition wall, so that liquid in the central cavity can overflow to the side cavity along a plurality of directions or even along the periphery of the whole partition wall, the liquid in the central cavity can flow uniformly, and the micropore atomization plate can reliably contact the liquid in the central cavity.

In order to strengthen the peripheral leakproofness of micropore atomizing piece, further technical scheme can also be, micropore atomizing piece arranges platform piece with between the first shell body micropore atomizing piece with thereby it lets to be located to arrange the second sealing washer between the first shell body the liquid in the micropore atomizing piece outside can not be followed micropore atomizing piece with the gap position seepage between the first shell body enters. In this way, the liquid above the microporous atomization sheet cannot easily permeate into the inner side of the first outer shell through the gap between the microporous atomization sheet and the first outer shell, so that the use environment inside the first outer shell is optimized.

The further technical scheme can also be that the first sealing ring and the second sealing ring are combined into a whole and sleeved on the periphery of the micropore atomization sheet. During the installation, earlier with disjunctor formula first sealing washer and second sealing washer cover in the periphery of micropore atomizing piece, then directly will overlap and establish the sealing washer micropore atomizing piece presss from both sides first shell body with between the platform spare, and need not respectively will first sealing washer and second sealing washer are fixed a position the installation, can the effectual efficiency that improves the installation to can reduce the degree of difficulty of installation.

The platform piece can be detachably connected to the first outer shell body through screws, and the micropore atomization sheet is clamped between the platform piece and the first outer shell body. Like this, through the screw with platform spare detachably install on first shell body, its dismouting is convenient, and can effectually with micropore atomizing piece presss from both sides tightly between platform spare and first shell body. Of course, the platform member of the present invention may also be mounted in other ways, such as by being connected to the first outer housing by a snap-fit connection, or by being connected to the first outer housing by a press-up structure, or by being connected to other components, such as a second outer housing as described below.

The technical scheme is that the device also comprises a control circuit board, wherein a control chip IC is arranged on the control circuit board, the micropore atomization sheet is connected to the control circuit board in a signal mode, and the control circuit board is arranged below the platform piece; the button not only penetrates through the first outer shell body, but also extends to a control contact point arranged on the control circuit board, so that the control contact point can be touched when the button is pressed. The control circuit board is disposed below the platform member, and the control circuit board is not limited to be disposed only below the bottom end of the platform member, and the control circuit board may also be installed in a nested manner as described below. The control circuit board drives the micropore atomization sheet to work under the triggering of the button.

The technical scheme can also be that an avoidance cavity is arranged in the central area of the control circuit board, and the control circuit board is sleeved on the platform piece through the avoidance cavity. In this way, not only can the control circuit board be radially positioned with the aid of the platform piece, but also the control circuit board is closer to the first outer casing, so that the length of the button arranged on the inner side of the first outer casing can be reduced, and the reliability of positioning the button can be improved.

The invention also provides a portable micropore atomization device which is characterized by comprising the atomization module which can be installed or used at multiple angles and a second outer shell body which is connected below the first outer shell body in a connecting mode, wherein a power pump capable of pumping liquid into the central cavity is arranged in the second outer shell body, and a pump outlet of the power pump is communicated with a liquid inlet pipe orifice of the central cavity through a liquid inlet pipe.

The power pump can select the adaptive water pumping quantity or water pumping lift and the like before assembly, or the power pump adjusts the adaptive water pumping quantity or water pumping lift and the like in real time during working, so that the liquid in the central cavity is ensured to reach certain pressure when the atomization module works. In the existing design, the most ideal state is that the working flow of the power pump is just adapted to the atomizing speed of the microporous atomizing sheet, for example, the outlet pressure of the power pump or the liquid pressure in the central cavity is detected by an automatic detection system, and then the working speed of the power pump is controlled by a controller. But in practice this is too costly and not cost effective. In a better scheme, two conventional power pumps are selected, namely a positive displacement pump which quantitatively supplies liquid to the central cavity so as to maintain and boost pressure, but the liquid supply amount of the positive displacement pump is generally larger than the atomization speed (from the viewpoint of optimization design, the liquid supply amount of the power pump is also required to be set to be larger than the atomization speed, so that the problem of insufficient atomization caused by various losses and errors can be avoided), and therefore, a return channel needs to be arranged on an outlet of the power pump or the central cavity so as to adjust the liquid flow in the central cavity; the centrifugal pump can provide liquid into the central cavity under constant pressure to maintain the pressure, but the outlet pressure of the centrifugal pump is generally larger than the actual liquid pressure required in the central cavity (from the viewpoint of optimization design, the liquid supply pressure of the power pump needs to be set to be larger than the actual atomization required pressure, so that the problem of insufficient atomization caused by various losses and errors can be avoided), and therefore, a backflow channel needs to be arranged at the outlet of the power pump or on the central cavity to adjust the liquid pressure in the central cavity. In the solution of the present invention, the backflow is actually achieved by using the overflow function of the overflow gap.

In this scheme, through the power pump will be used for the atomizing liquid pump to go into in the central cavity, and need not to adopt traditional drain cotton core, overcome the easy problem of rotten and drain speed slowdown that drain cotton core exists.

The further technical scheme can also be, still include the external interface that charges, be provided with the confession on first shell body or the second shell body the external exposed mouth that charges of external interface still including setting up battery in the second shell body, the battery with the external interface electricity signal connection that charges. The micropore atomization device can normally work under the condition of no external power supply due to the battery, and is convenient for users to carry and use. Wherein the battery mainly supplies power for the control circuit board and the power pump.

The technical scheme can also be that the water storage device further comprises a water storage bottle which is detachably connected to the lower portion of the second outer shell, and the water storage bottle further comprises a liquid guiding pipe communicated with a pump inlet of the power pump, and the liquid guiding pipe extends into the water storage bottle. The drainage tube can be an independent water tube which penetrates through the water storage bottle to enter the water storage bottle, and the drainage tube can also be formed by communicating and combining a plurality of sections of pipelines. According to the invention, the water storage bottle is arranged below the second outer shell, so that when the platform part is provided with the side cavity, liquid in the side cavity can conveniently flow back into the water storage bottle through gravity.

In order to prevent the air pressure in the water storage bottle from being too low or too high, the technical scheme can be that the bottle opening of the water storage bottle is further provided with a bottle cap, air holes are further formed in the bottle cap, an interval air film is arranged on the air holes and used for allowing air to pass through but not allowing liquid in the water storage bottle to circulate through, and the liquid guide pipe penetrates through the bottle cap and extends into the water storage bottle. The air-permeable valve is characterized in that the air-permeable valve is provided with a plurality of air-permeable micropores for allowing air to pass through but not allowing liquid to pass through, and the air-permeable valve can be matched with the bracket to form the air-permeable valve with an air-permeable function.

The air flow communication is carried out between the water storage cavity of the water storage bottle and the external space through the air separation film, so that the self-pressure-maintaining function of the water storage cavity is realized, the adverse effects caused by high pressure generated in the assembly process of the water storage bottle and negative pressure generated after the later water quantity is reduced can be prevented, the requirement on the pressure resistance of the water storage bottle is reduced, and the requirement can be met even if the water storage bottle adopts a plastic thin bottle with lower pressure resistance.

The water storage bottle further comprises a return pipe communicated with the return pipe orifice, and the return pipe penetrates through the second outer shell to extend into the water storage bottle. The backflow pipe can be an independent water pipe which penetrates through the water storage bottle to enter the water storage bottle, and the backflow pipe can also be formed by communicating and combining a plurality of sections of pipelines.

The invention has the characteristics and advantages, so the invention can be used in the atomizing module and the portable micropore atomizing device which can be installed or used at multiple angles.

The location and the structure of the arrangement of said overflow gap 5 can be found here in order to achieve its functional role. Wherein the overflow gap 5 firstly has an overflow channel structure capable of overflowing so as to overflow the excess liquid in the central cavity 31 (excess liquid = liquid entering from the liquid inlet nozzle 32 — liquid that the micro-porous atomizing sheet 2 has atomized) into the side cavity 33; secondly, when the microporous atomization sheet 2 is placed at a position above the liquid in the central cavity 31, the microporous atomization sheet 2 is in a horizontal state at this time, the liquid level of the liquid in the central cavity 31 is also in a horizontal state, the liquid in the central cavity 31 needs to overflow the top wall surface of the partition wall 35, at this time, the top wall surface of the partition wall 35 not only defines the lowest position of the overflow, but also defines that the liquid level of the liquid in the central cavity 31 is certainly not lower than the top wall surface of the partition wall 35, otherwise, the overflow cannot be formed, and the overflow liquid level defined by the top wall surface of the partition wall 35 is higher than the top wall surface of the partition wall 35. To this end, the height of the overflow gap 5 is suitable for allowing overflow liquid to contact the microporous atomizing sheet 2 so as to keep the microporous atomizing sheet 2 atomizing, and firstly, the characteristic actually includes that the distance between the microporous atomizing sheet 2 and the partition wall 35 is a height distance which allows the liquid surface of the liquid to contact the microporous atomizing sheet 2, and the distance is large enough for the overflow liquid level defined by the top wall surface of the partition wall 35 to be higher than the top wall surface of the partition wall 35 so that the liquid can contact the microporous atomizing sheet 2 when the liquid flows over the top wall surface of the partition wall 35, for example, when the atomizing module is used in a portable microporous atomizing device with a small size, the distance can be 2-3mm, and of course, in combination with the lift and liquid outlet amount of the power pump 8, the atomizing speed of the microporous atomizing sheet 2, and the size of the central cavity 31, the size of the interval can also select other values which can meet the requirements of the invention; secondly, this feature also includes the fact that the liquid in the central cavity 34 is already filled with liquid in the central cavity 31, since the liquid in the central cavity 34 contacts the microporous atomizing sheet 2, so that the microporous atomizing sheet 2 can maintain its atomization when the microporous atomizing sheet 2 is swung (mounted or moved) to a position above the liquid in the central cavity 34. For example, the overflow gap 5 is made to be a flat structure, a small gap is provided between the microporous atomization sheet 2 and the partition wall 35 in the height direction (at this time, a structure that multiple points contact is provided between the microporous atomization sheet 2 and the top wall surface of the partition wall 35 is not excluded), but a relatively wide overflow width is provided in the horizontal direction, so that the overflow gap 35 can overflow and simultaneously allow the overflow liquid level to contact the microporous atomization sheet 2, and the liquid in the central cavity 31 is always kept in a full state. When the central chamber 31 is filled with liquid, the central chamber 31 is filled with liquid but does not necessarily have a high intra-chamber pressure.

The relief gap 5 may be a continuous structure or an intermittent structure; secondly, the micro-porous area of the micro-porous atomizing sheet 2 may extend from the upper area of the central cavity 31 to the upper area of the overflow gap 5; in addition, since the micro-porous atomizing sheet 2 has micro-pores which can exhaust the gas in the central cavity 31, the liquid can be kept in the filling state in the central cavity 31 at any time.

Stated further, from another perspective, the liquid level inside the central cavity 31 reaches to contact the microporous atomization sheet, and is also related to the pressure or flow rate of the liquid entering the central cavity 31 from the liquid inlet nozzle 32 of the central cavity 31, wherein the liquid level inside the central cavity 31 is easier to reach to contact the microporous atomization sheet 2 the greater the pressure or flow rate of the liquid entering from the liquid inlet nozzle 32 is; next, the size of the overflow gap 5 is affected by the lift of the power pump 83, the amount of liquid discharged, and other factors, such as the atomizing speed of the micro atomizing sheet 2. The size of the overflow gap 5 can be freely selected on the premise that the pressure in the central cavity 31 does not cause a large amount of liquid to be directly extruded out of the micropores of the microporous atomizing sheet 2, and the microporous atomizing sheet 2 can contact enough liquid. For this reason, it can be seen that the size of the overflow gap 5 is selected only by making a selective design problem of specific values under the design concept and design structure disclosed in the embodiment of the present invention, which is not considered in this embodiment as an important point, and the pressure or flow rate of the liquid entering the liquid inlet pipe orifice 32 in this embodiment is mainly considered on the assumption that the parameters thereof are selected, and therefore the arrangement structure of the overflow gap 5 itself is the most basic structure. The filling state of the liquid in the central cavity 31 means that the central cavity 31 is filled with the liquid but does not necessarily have a high intra-cavity pressure.

In another embodiment (not shown in the figures), it may also be a flow groove directly spaced on the partition wall 35, and when the microporous atomization sheet 2 is tightly mounted between the top wall surface of the partition wall 35 and the microporous atomization sheet 2 covers the flow groove and constitutes a liquid flow passage, i.e. the overflow gap 5.

In the present embodiment, the microporous atomizing sheet 2 is placed at the position above the liquid in the central cavity 31, which is an installation angle position or a use angle position using the microporous atomizing sheet 2, because the liquid level is always in the horizontal direction in the free state, for this reason, the microporous atomizing sheet 2 is placed at the position above the liquid in the central cavity 31, and in fact, the microporous atomizing sheet 2 is also placed at the position above the liquid in the central cavity 31, which is an extreme position where the microporous atomizing sheet 2 is placed, because at other angle positions the microporous atomizing sheet 2 is more or less easily contacted with the liquid, and when the microporous atomizing sheet 2 is placed at the position above the liquid in the central cavity 31, the water level can also be contacted through the structure of the overflow gap 5, other angular positions are more accessible to the water level.

According to the scheme, liquid enters the central cavity 31 from the liquid inlet pipe orifice 32 of the central cavity 31, overflows into the side cavity 33 through the overflow gap 5, and then flows out through the backflow pipe orifice 34. Wherein when the microporous atomizing sheet 2 is placed in a position above the liquid inside the central cavity 31, the partition wall 35 is arranged to allow the liquid level inside the central cavity 31 to reach a position contacting the microporous atomizing sheet 2, thereby ensuring that the liquid is also atomized in this angular position. Compared with the prior art, the atomizing module of the invention, firstly, because the micropore atomizing sheet 2, the first sealing ring 41 and the platform piece 3 form the atomizing module which can contain liquid and overflow liquid and can be installed or used at various angles, the use flexibility of the atomizing module is greatly improved, and the atomizing module can be freely used without being limited by angles particularly when being used in a handheld atomizing device; secondly, the overflow gap 5 is directly formed between the microporous atomization sheet 2 and the partition wall 35, so that the structure of the atomization module 100 is greatly simplified, and the encumbrance is reduced; thirdly, this is simple 5 structure of overflow gap itself, not only can the overflow, moreover 5 highly be suitable for let overflow liquid can contact thereby can let 2 of micropore atomizing piece keep atomizing, let liquid can remain at filling state in the central cavity 35 all the time, just that can let based on this state micropore atomizing piece 2 is put to being located at any time the liquid level also can reach when the top position of the inside liquid of central cavity 35 the micropore atomizing piece 2 thereby can let the atomizing module keep at atomizing state.

It should be noted that the backflow pipe port 34 may be communicated with a water storage bottle 91 described below, so as to backflow the liquid in the side cavity 33 into the water storage bottle 91, and the backflow pipe port 34 may also be communicated with the power pump 8 as a backflow structure of the power pump 8, and of course, the backflow pipe port 34 may also be communicated with other suitable positions.
