Description

Technical Field

[0001] The present invention relates to an atomizing device, which can adjust the humidity of the surrounding space. The present invention particularly relates to an atomizing device with water level detection, which senses whether the liquid level in the base reaches a set value through a metal sleeve. The atomizing device can be a desktop atomizer or a mobile vehicle-mounted atomizer. The atomizer can be used to atomize water, sesame oil, or medicine. Background Art

[0002] As an electrical appliance for increasing the humidity of the environment, atomization equipment is currently widely used in relatively closed spaces such as indoors and in cars. The atomization equipment in the prior art generally adopts ultrasonic atomization sheets or microporous atomization sheets, among which microporous atomization sheets are mostly used for small, portable liquid atomization equipment, which generally includes a water storage chamber, a microporous atomization sheet, and a liquid-conducting cotton strip that conducts water in the water storage chamber to the microporous atomization sheet.

[0003] However, microporous atomizing sheet type atomizing equipment generally does not have a water level detection function. Even if some atomizing equipment is provided with a water level detection function, a water level probe is directly installed on the component in the space above the liquid surface of the water storage chamber. If the water level probe is to detect the lowest liquid level of the atomizing equipment, the water level probe needs to be designed into a longer structure. The water level probe with a longer structure is unstable, and long-term use will cause the water level probe to loosen.

[0004] For example, the Chinese utility model patent with authorization announcement number CN 209068658 U discloses a humidifier water level detection circuit, including a humidifier 1, a cotton core 2, an atomizer 3, an electronic circuit board 4, and a water level detection needle 5. The cotton core 2 is provided at the center of the humidifier 1, the atomizer 3 is provided with a first terminal 31 for detecting the water level of an atomizer sheet and a second terminal 32 for detecting the water level of an atomizer sheet, the upper side of the cotton core 2 is connected to the first terminal 31 for detecting the water level of an atomizer sheet, the electronic circuit board 4 is provided with a first terminal 41 for detecting the water level of an atomizer sheet and a second terminal 42 for detecting the water level of an atomizer sheet through a wire, and the first terminal 41 for detecting the water level of an atomizer sheet is connected in series with the water level detection needle 5 through a wire. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an atomizing device with water level detection, which uses a metal sleeve to sense whether the liquid level in the base has reached a set value to prevent the atomizing device from atomizing without water, and the metal sleeve is installed in a set manner to improve the stability of the structure.

[0006] In view of the technical problems raised above, the present invention discloses an atomization device with liquid level detection, comprising a base, the base being used to store atomization liquid; an integrated module, the integrated module being provided with a main control circuit and a microporous atomization sheet, the microporous atomization sheet being used to atomize liquid under the control of the main control circuit; a liquid guiding core rod, the top end of which is in contact with the bottom of the microporous atomization sheet, the liquid guiding core rod extending from the integrated module into the base, the liquid guiding core rod being used to allow the liquid in the base to crawl onto the microporous atomization sheet; and a core rod tube, the core rod tube containing It includes an upper core rod tube arranged in the integrated module and a lower core rod tube arranged outside the integrated module, the liquid-conducting core rod is inserted into the core rod tube, at least part of the lower core rod tube extends into the base, and a rod liquid inlet is provided at the lower end of the lower core rod tube, and the rod liquid inlet is used to allow the liquid in the base to enter the core rod tube for adsorption by the liquid-conducting core rod; it also includes a metal sleeve for liquid level sensing, the metal sleeve is sleeved on the outside of the lower core rod tube and is electrically connected to the main control circuit in the integrated module, and there is a spacing between the rod liquid inlet and the metal sleeve.

[0007] The integrated module is provided with a main control circuit and a microporous atomizer sheet, and it is defined that the main control circuit and the microporous atomizer sheet are arranged in the inner cavity of the integrated module, and the inner cavity of the integrated module refers to the space enclosed by the outermost components of the integrated module, such as the space enclosed by the module housing and the lower end cover described below. The main control circuit and the microporous atomizer sheet are both integrated components of the integrated module.

[0008] Among them, the microporous atomization sheet has an atomization hole, and the microporous atomization sheet is connected to a driving circuit. The driving circuit can be arranged on the main control circuit and controlled by the main control circuit. The main control circuit controls the driving circuit to drive the microporous atomization sheet to vibrate at a high frequency, so that the liquid inside the microporous atomization sheet is driven by the high-frequency vibrating microporous atomization sheet to be sprayed outward through the atomization hole. When the liquid is forced to pass through the atomization hole, it will form droplets with smaller particle size, thereby forming an atomization effect on the outside of the microporous atomization sheet, thereby humidifying the nearby air.

[0009] The liquid-conducting core rod is made of a material that has a capillary effect with the liquid in the base so that the liquid can be conducted along the liquid-conducting core rod. When the amount of liquid in the base is sufficient, the liquid in the base crawls along the liquid-conducting core rod to the microporous atomizing sheet under the capillary effect of the liquid-conducting core rod, thereby achieving the purpose of supplying atomization liquid to the microporous atomizing sheet through the liquid-conducting core rod. The liquid-conducting core rod can be a liquid-conducting cotton strip.

[0010] Wherein, the mandrel tube includes an upper mandrel tube arranged in the integrated module and a lower mandrel tube arranged outside the integrated module, and it is defined that the mandrel tube includes at least the upper mandrel tube and the lower mandrel tube, the upper mandrel tube is located in the inner cavity of the integrated module, and the lower mandrel tube is located outside the inner cavity of the integrated module. The mandrel tube can be an integral structure or a split structure, and is not limited to being an integral structure with other components such as the lower end cover described below.

[0011] Among them, the lower end of the lower core rod tube is provided with a rod liquid inlet, which defines that the lower end of the lower core rod tube will not hinder the liquid in the base from contacting the lower section of the liquid-conducting core rod, so that the liquid-conducting core rod can smoothly absorb the liquid in the base.

[0012] Among them, the metal sleeve is sleeved on the outside of the lower core rod tube and is electrically connected to the main control circuit in the integrated module, and it is defined that when the liquid level in the base can allow the liquid to enter the lower core rod tube and be adsorbed onto the liquid-conducting core rod, and at the same time can allow the liquid to contact the metal sleeve, the metal sleeve, the liquid in the base, the liquid on the liquid-conducting core rod and the microporous atomization sheet form a signal communication path to achieve electrical signal conduction with the main control circuit.

[0013] Among them, there is a spacing between the rod liquid inlet and the metal sleeve, which defines that when the liquid level in the base does not reach the bottom of the metal sleeve, the resistance between the metal sleeve and the liquid in the base increases sharply due to the spacing, and the loop current signal becomes very weak. At this time, a short circuit is almost formed between the metal sleeve and the microporous atomization sheet.

[0014] According to the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The present invention sleeves the metal sleeve on the outer side of the lower mandrel tube, which is not only compact in structure, but also stable and reliable, and easy to install and manufacture;

[0016] 2. The metal sleeve can also be used to protect the liquid-conducting core rod and the lower core rod tube from being deformed or broken by external impact;

[0017] 3. Allow the metal sleeve and the lower mandrel tube to cooperate with each other to improve the impact resistance;

[0018] 4. The atomization device of the present invention cleverly uses the metal sleeve and the liquid in the base and the liquid on the liquid-conducting core rod as electrical signals to connect the intermediate conductor of the microporous atomization sheet, thereby realizing detection of whether the liquid level in the base has reached the set height, which can prevent the microporous atomization sheet from continuing to work without sufficient liquid, thereby protecting the atomization device. Because when the liquid level in the base reaches the set height, the metal sleeve, the liquid in the base, the liquid on the liquid-conducting core rod and the microporous atomization sheet form a signal communication path to realize electrical signal conduction with the main control circuit. At this time, the microporous atomization sheet works normally; on the contrary, if the liquid level in the base does not reach the set height, due to the spacing between the metal sleeve and the liquid in the base, the resistance will increase sharply, and the loop current signal will become very weak. At this time, the metal sleeve and the microporous atomization sheet are almost disconnected, and the main control circuit controls the microporous atomization sheet to stop working;

[0019] 5. The atomizing device of the present invention can also prevent the atomizing device from having a dry burning problem when the liquid-conducting core rod cannot conduct liquid normally, because the liquid-conducting core rod cannot conduct liquid to the microporous atomizing sheet, and at this time, a circuit is almost formed between the metal sleeve and the microporous atomizing sheet, and the microporous atomizing sheet will also stop working;

[0020] 6. The present invention inserts the liquid-conducting core rod into the core rod tube. The core rod tube can not only protect the liquid-conducting core rod from damage by the surrounding environment, but also prevent the liquid on the liquid-conducting core rod from emitting into the inner cavity of the integrated module, thereby improving the safety and service life of the electrical components in the integrated module. In addition, the wrapped liquid-conducting core rod can reduce the loss of liquid in the process of conducting liquid upward, thereby not affecting the conduction efficiency of the liquid-conducting core rod.

[0021] In order to prevent the metal sleeve and the liquid-conducting core rod from being electrically connected through the liquid remaining on the surface of the components when the liquid level is low, a further technical solution may be that a detachable insulating sealing ring is also mounted on the lower outer side of the lower core rod tube, the metal sleeve stands on the insulating sealing ring, and the lower outer side of the lower core rod tube and the metal sleeve are sealed and insulated by the insulating sealing ring. In this way, when the liquid level is lower than the insulating sealing ring, the gap between the tube tail support and the lower core rod tube cannot enter the conductive liquid, and of course the liquid-conducting core rod and the metal sleeve cannot achieve electrical signal conduction with the help of the liquid.

[0022] A further technical solution may be that a detachable tube tail support is installed at the tube tail of the lower core rod tube, and a pressure spring is arranged between the tube tail support and the liquid-conducting core rod, the tube tail support is used to support the pressure spring, and the pressure spring is used to press the liquid-conducting core rod upward, and the tube tail support does not hinder the liquid in the base from entering the core rod tube from the rod liquid inlet and being adsorbed onto the liquid-conducting core rod.

[0023] Among them, the tube tail support does not hinder the liquid in the base from entering the core rod tube from the rod liquid inlet and being adsorbed to the liquid-conducting core rod, and defines that the rod liquid inlet will not be closed by the tube tail support. For example, it can be connected with the rod liquid inlet through the support liquid inlet described below, or a certain installation gap is left between the tube tail support and the lower core rod tube, so that the liquid in the base can flow from the rod liquid inlet into the lower core rod tube.

[0024] The present invention uses the pressure spring to always subject the liquid-conducting core rod to an upward spring force, and the liquid-conducting core rod will contact the bottom of the microporous atomizing sheet under the action of this spring force. In addition, the present invention supports the lower end of the pressure spring through the tube tail support, and the tube tail support is also a support carrier for the liquid-conducting core rod. Since the tube tail support can be detachably installed on the tube tail of the core rod tube, if the liquid-conducting core rod needs to be repaired or replaced, the integrated module is first disassembled, and then the tube tail support is removed to remove the liquid-conducting core rod.

[0025] A further technical solution may be that the tube tail support is provided with a support chamber opening upward, one end of the pressure spring extends into the support chamber, and the other end is connected to the liquid-conducting core rod, and the tube tail support is provided with a support member liquid inlet connected to the rod liquid inlet. The present invention can restrict the lower end position of the pressure spring to a certain extent through the support chamber to prevent the pressure spring from being offset.

[0026] When the atomizing device of the present invention is provided with a tube tail support, as a technical solution to replace the above-mentioned insulating sealing ring, a detachable insulating sealing ring can also be mounted on the lower outer side of the lower core rod tube, the insulating sealing ring comprising a sealing ring upright portion and a sealing ring edge portion connected to the lower part of the sealing ring upright portion and extending radially outward, the metal sleeve and the lower outer side of the lower core rod tube are sealed via the sealing ring upright portion, the lower end of the metal sleeve stands on the sealing ring edge portion, the tube tail support is snap-connected to the lower core rod tube and can squeeze the sealing ring edge portion upward so that the sealing ring edge portion is tightly fitted with the tube tail support, the lower core rod tube and the metal sleeve respectively, and the tube tail support is an insulator. In this way, the insulating sealing ring is used to achieve sealing between the tube tail support, the lower core rod tube and the metal sleeve, preventing liquid from entering the gap between the tube tail support and the lower core rod tube, so that the liquid electrical signal in the gap connects the metal sleeve and the liquid guiding core rod. In addition, the insulating sealing ring is easy to install. During installation, the insulating sealing ring is first put on the outside of the lower core rod tube, and then the tube tail support is buckled on the lower end of the lower core rod tube to simultaneously squeeze the insulating sealing ring upward and lock it.

[0027] A further technical solution may be that the integrated module also includes a module shell, and a lower end cover is also arranged on the inner lower part of the module shell, the main control circuit and the microporous atomization sheet are located in the space above the lower end cover, the lower core rod tube is connected to the lower end cover and is integrally formed with the lower end cover, the lower core rod tube extends downward into the base, and a first cover sealing ring is arranged between the module shell and the lower end cover, the first cover sealing ring is used to prevent the liquid in the base from penetrating from the gap between the module shell and the lower end cover into the space above the lower end cover; the top of the metal sleeve is provided with a wiring end extending upward, and the lower end cover is provided with a wiring end connecting hole for the wiring end to pass upward into the upper part of the lower end cover, and the wiring end is sealed and connected to the lower end cover.

[0028] The present invention provides a wiring end connecting hole for the wiring end to pass through on the lower end cover so that the metal sleeve can be connected to the main control circuit above the lower end cover, and due to the stability of the metal sleeve sheath structure, the metal sleeve is not prone to shaking, so the wiring end and the lower end cover can maintain good sealing for a long time. For example, when the wiring end and the wiring end connecting hole of the lower end cover are sealed by glue, the sealing glue is not prone to cracks during long-term use to affect the sealing performance.

[0029] A further technical solution may be that a liquid level indicator light is provided in the integrated module, and the liquid level indicator light signal is connected to the main control circuit, and the main control circuit is used to respond to the liquid level information provided by the metal sleeve and control the liquid level indicator light to emit a light indication signal. The present invention can issue a water shortage warning to the user through the liquid level indicator light, and the user can judge whether to add water according to the light indication signal.

[0030] A further technical solution may be that the module shell includes at least one module shell top wall portion with its outer surface arranged upward, the module shell top wall portion is provided with a module shell mist hole and a module shell air outlet hole, the module shell air outlet hole is arranged on the side of the module shell mist hole, a blower controlled by the main control circuit is arranged in the module shell, the module shell mist hole is used to draw out the mist generated by the microporous atomization sheet, the module shell air outlet hole is used to draw out the wind blown by the blower, the liquid level indicator light is located on the inner side of the module shell top wall portion, and the module shell top wall portion is also used to allow the light emitted by the liquid level indicator light to be transmitted.

[0031] The module housing air outlet is used to lead the wind blown by the blower upward, and it is defined that there is a wind connection relationship between the module housing air outlet and the blower. The module housing includes at least one module housing top wall portion with an outer surface facing upward, and it is defined that relative to the horizontal plane, it has a module housing top wall portion for setting the module housing mist hole and the module housing air outlet, wherein the module housing top wall portion can be set in a horizontal direction or in an inclined direction. The outer surface of the module housing top wall portion is arranged upward so that the mist sprayed by the module housing mist hole arranged thereon can be sprayed vertically or obliquely upward, and the wind led by the module housing air outlet arranged thereon is also discharged vertically or obliquely upward; in addition, since the module housing air outlet is arranged beside the module housing mist hole, when the wind blown by the blower is led upward by the module housing air outlet, it will drive the mist sprayed by the module housing mist hole arranged beside it to spray in a farther direction.

[0032] A further technical solution may be that an island portion is provided in the module shell, the island portion is mounted on the upper core rod tube, a battery cavity and a fan cavity are also provided on the island portion, the battery cavity and the fan cavity are arranged on the left and right, a battery for providing driving power is provided in the battery cavity, and the blower is arranged in the fan cavity.

[0033] The battery mainly provides the main control circuit and the blower with the required electrical energy. The atomizing device of the present invention can work normally without an external power source because it has a battery, and is convenient for users to carry and use.

[0034] Among them, the present invention uses the island portion as a carrier for the blower and the battery, and the integrated installation of the blower and the battery can facilitate the overall assembly of the integrated module, and the atomization device rationally utilizes the space of the integrated module to increase the function of storing electrical energy.

[0044] Combine the following Figures 1 to 7 The structure of the atomization equipment using the technical solution of the present invention is further described.

[0045] like Figure 1 and Figure 2As shown, the present invention discloses an atomization device, and particularly relates to a movable atomization device, including a base 100 and an integrated module 200, wherein a liquid storage cavity 11 with an opening facing upward is arranged on the base 100, that is, the liquid storage cavity 11 is arranged in the base 100, and the liquid storage cavity 11 of the base 100 is used to store liquid for atomization, and the liquid can be water, sesame oil or medical drugs.

[0046] The integrated module 200 is arranged on the base 100, and the integrated module 200 includes a module housing 21, and the module housing 21 is barrel-shaped, and the module housing 21 is vertically connected to the base 100. In another embodiment, in particular, in a structural embodiment in which the module housing 21 is not completely required to be vertically connected to the base 100, the integrated module 200 and the base 100 may also be arranged left and right, as long as it can ensure that the liquid in the liquid storage cavity 11 of the base 100 can be adsorbed onto the integrated module 200.

[0047] The integrated module 200 has an inner cavity, which is part or all of the barrel cavity of the module housing 21. A microporous atomizing sheet 22 and a main control circuit 23 are arranged in the inner cavity of the integrated module 200. The microporous atomizing sheet 22 is used to atomize liquid under the control of the main control circuit 23. The module housing 21 includes at least one module housing top wall portion 211 with an outer surface facing upward, wherein the module housing top wall portion 211 is arranged in a horizontal direction; a module housing mist hole 212 is arranged on the module housing top wall portion 211, and the module housing mist hole 212 is used to allow the mist atomized by the microporous atomizing sheet 22 to be sprayed upward from the module housing mist hole 212, that is, the module housing mist hole 212 is used to lead out the mist generated by the microporous atomizing sheet 22. The outer surface of the module housing top wall portion 211 is arranged upward so that the mist sprayed by the module housing mist hole 212 arranged thereon can be sprayed vertically upward. In other embodiments, the module housing top wall 211 may also be arranged in an inclined direction. In this case, the outer surface of the module housing top wall 211 is arranged upward so that the mist sprayed from the module housing mist hole 212 arranged thereon can be sprayed upward at an angle. Among them, the inner cavity of the integrated module 200 refers to the space enclosed by the outermost components of the integrated module 200, and in this embodiment specifically refers to the space enclosed by the module housing 21 and the lower end cover 3 described below. Among them, the microporous atomization sheet 22 and the main control circuit 23 are located in the module housing 21, and are also located in the space above the lower end cover 3.

[0048] Among them, the microporous atomization sheet 22 has an atomization hole, and the microporous atomization sheet 22 is connected to a driving circuit. The driving circuit can be set in the main control circuit 23 or arranged separately. The microporous atomization sheet 22 oscillates at a high frequency under the drive of the driving circuit, that is, the main control circuit 23, so that the liquid under (inside) the microporous atomization sheet 22 is driven by the high-frequency vibration of the microporous atomization sheet 22 to be sprayed out through the atomization hole. When the liquid is forced to pass through the atomization hole, it will form droplets with smaller particle size, and then form an atomization effect on the outside of the microporous atomization sheet 22, thereby removing dust, humidifying or adding fragrance to the nearby air.

[0049] In order to achieve the conduction of liquid, the atomization device of the present invention further includes a liquid conducting core rod 24, which is used to allow the liquid in the liquid storage chamber 11 to crawl onto the microporous atomization sheet 22. The upper section of the liquid conducting core rod 24 is arranged in the inner cavity of the integrated module 200, and the top of the liquid conducting core rod 24 is in contact with the bottom of the microporous atomization sheet 22, and the lower section of the liquid conducting core rod 24 is arranged outside the inner cavity of the integrated module 200, and the lower section of the liquid conducting core rod 24 can extend into the liquid storage chamber 11, that is, the liquid conducting core rod 24 extends from the integrated module 200 to enter the base 100.

[0050] The liquid-conducting core rod 24 of the present invention is made of a material that has a capillary effect with the liquid in the liquid storage chamber 11 so that the liquid is conducted along the liquid-conducting core rod 24. In this embodiment, the liquid-conducting core rod 24 is made of a liquid-conducting cotton strip. Since the top of the liquid-conducting core rod 24 is in contact with the bottom of the microporous atomizing sheet 22, and the lower end is located in the outer cavity of the integrated module 200 and extends into the liquid storage chamber 11, when the amount of liquid in the liquid storage chamber 11 is sufficient, the liquid in the liquid storage chamber 11 crawls along the liquid-conducting core rod 24 to the lower surface of the microporous atomizing sheet 22 under the capillary action of the liquid-conducting core rod 24, thereby achieving the purpose of supplying the microporous atomizing sheet 22 with liquid for atomization through the liquid-conducting core rod 24.

[0051] like Figure 3 and Figure 4As shown, the module housing 21 is arranged axially, and a lower end cover 3 arranged radially is also provided at the inner lower part of the module housing 21, and the lower end cover 3 is sleeved on the liquid guiding core rod 24, and the liquid guiding core rod 24 extends downward after passing through the lower end cover 3, and the inner cavity of the integrated module 200 is formed between the module housing 21 and the lower end cover 3, and a first cover sealing ring 31 is provided between the module housing 21 and the lower end cover 3, and the lower end cover 3 and the module housing 21 are sealed by the first cover sealing ring 31, wherein the first cover sealing ring 31 is used to prevent the liquid outside the inner cavity of the integrated module 200, such as the liquid in the liquid storage cavity 11, from penetrating from the gap between the module housing 21 and the lower end cover 3 to the space above the lower end cover 3, i.e., the inner cavity of the integrated module 200. The lower end cover 3 is detachably locked to the module housing 21 by a snap-on method, and in other embodiments, the lower end cover 3 can also be detachably locked to the module housing 21 by a screw-on method or the like.

[0052] It should be noted that the lower end cover 3 can be an integrated structure or a split structure. In this embodiment, the lower end cover 3 is a split structure. Specifically, the lower end cover 3 includes a partition cover portion 3a and a locking ring portion 3b which are separately arranged. The partition cover portion 3a is sleeved on the liquid-conducting core rod 24, and the partition cover portion 3a and the module housing 21 are sealed by the first cover sealing ring 31; the locking ring portion 3b is annular and located below the partition cover portion 3a, and the locking ring portion 3b is detachably locked to the module housing 21. The locking ring portion 3b is locked to the module housing 21 by snapping. In other embodiments, the locking ring portion 3b can also be locked to the module housing 21 by screwing, etc., and the screwing is a threaded connection, etc. In addition, the locking ring portion 3b is detachably locked to the module housing 21 for axially pressing the partition cover portion 3a. The partition cover portion 3a is axially positioned under the support of the locking ring portion 3b below it. An island portion 6 and an intermediate mold frame 7 are arranged above the partition cover portion 3a. The partition cover portion 3a, the island portion 6 and the intermediate mold frame 7 are axially limited between the locking ring portion 3b and the module housing top wall portion 211. In another embodiment, the partition cover portion 3a can also be used as a limiting structure above it by a rib structure arranged on the module housing 21. The lower end cover 3 adopts a split structure and is detachably locked to the module housing 21 by the locking ring portion 3b. After all the components to be accommodated in the module housing 21 are axially assembled, they can be locked once by the locking ring portion 3b, thereby facilitating assembly, disassembly and maintenance.

[0053] Furthermore, the atomization device of the present invention further comprises a core rod tube (4a, 4b), wherein the core rod tube (4a, 4b) is sleeved on the outside of the liquid-conducting core rod 24, or the liquid-conducting core rod 24 is inserted into the core rod tube (4a, 4b), and the microporous atomization sheet 22 is located above the core rod tube (4a, 4b). The core rod tube (4a, 4b) comprises an upper core rod tube 4a arranged in the integrated module 200, i.e., in the inner cavity of the integrated module 200, and a lower core rod tube 4b arranged outside the integrated module 200, i.e., outside the inner cavity of the integrated module 200, and at least part of the lower core rod tube 4b extends into the base 100.

[0054] Among them, the upper core rod tube 4a is connected to the lower end cover 3, and the upper core rod tube 4a is in the space above the lower end cover 3, and the upper core rod tube 4a extends in the module shell 21, that is, in the inner cavity of the integrated module 200 in the up and down direction, and the upper section of the liquid-conducting core rod 24 penetrates into the upper core rod tube 4a, and the microporous atomization sheet 22 is located above the upper core rod tube 4a. A second cover sealing ring 32 is arranged between the upper core rod tube 4a and the lower end cover 3, and a sealed connection is achieved through the second cover sealing ring 32. The present invention improves the sealing between the upper core rod tube 4a and the lower end cover 3 through the second cover sealing ring 32, which can prevent the liquid in the liquid storage chamber 11 from flowing into the inner cavity of the integrated module 200 through the gap between the upper core rod tube 4a and the lower end cover 3.

[0055] The lower mandrel tube 4b is also connected to the lower end cover 3, and the lower mandrel tube 4b extends downward and extends into the base 100, that is, the liquid storage chamber 11. The lower section of the liquid-conducting mandrel 24 is arranged below the lower end cover 3 and extends downward, and the lower section of the liquid-conducting mandrel 24 penetrates into the lower mandrel tube 4b. The lower mandrel tube 4b does not prevent the liquid in the liquid storage chamber 11 from contacting the lower section of the liquid-conducting mandrel 24, that is, the lower mandrel tube 4b does not prevent the liquid from entering the lower mandrel tube 4b and being adsorbed onto the liquid-conducting mandrel 24, which of course also means that the mandrel tubes (4a, 4b) do not prevent the liquid from entering the mandrel tubes (4a, 4b) and being adsorbed onto the liquid-conducting mandrel 24. The lower mandrel tube 4b is connected to the lower end cover 3 and is integrally formed with the lower end cover 3.

[0056] In this embodiment, the lower mandrel tube 4b and the lower end cover 3 are an integrated structure, the upper mandrel tube 4a and the lower end cover 3 are a split structure, and the upper mandrel tube 4a and the lower end cover 3 are sealed by the second cover sealing ring 32. In another embodiment, the lower mandrel tube 4b and the upper mandrel tube 4a are an integrated structure, and the integrated mandrel tubes (4a, 4b) are sealed and connected to the lower end cover 3; in another embodiment, the upper mandrel tube 4a and the lower end cover 3 are an integrated structure, and the lower mandrel tube 4b and the lower end cover 3 are a split structure. In this case, a cover sealing ring can be provided between the lower mandrel tube 4b and the lower end cover 3 to achieve a sealed connection between the two.

[0057] The side of the liquid-conducting core rod 24 described in the present invention is wrapped within the upper core rod tube 4a, the lower end cover 3 and the lower core rod tube 4b, which can not only protect the liquid-conducting core rod 24 from damage by the surrounding environment, but also ensure that the inner cavity of the integrated module 200 outside the upper core rod tube 4a is protected from erosion by the liquid on the liquid-conducting core rod 24, thereby improving the safety and service life of the electrical components in the integrated module 200. In addition, the wrapped liquid-conducting core rod 24 is not easy to lose liquid in the process of conducting liquid upward, thereby not affecting the conduction efficiency of the liquid-conducting core rod 24.

[0058] like Figure 5 As shown, in order to ensure that the liquid-conducting core rod 24 and the microporous atomizing sheet 22 always maintain a reliable contact state, a pressing spring 41 is provided at the tail end of the lower core rod tube 4b, and the pressing spring 41 is used to press the liquid-conducting core rod 24 upward. In this way, the liquid-conducting core rod 24 is always subjected to an upward spring force, and the liquid-conducting core rod 24 will contact with the bottom of the microporous atomizing sheet 22 under the action of this spring force, thereby ensuring that the liquid-conducting core rod 24 and the microporous atomizing sheet 22 always maintain a reliable contact state.

[0059] Furthermore, in order to facilitate the disassembly and assembly of the liquid-conducting core rod 24, a detachable tube tail support 42 is installed at the tube tail of the lower core rod tube 4b, and the tube tail support 42 is detachably connected to the lower core rod tube 4b by a snap-fit ​​connection. The top pressure spring 41 is arranged between the tube tail support 42 and the liquid-conducting core rod 24, that is, the top pressure spring 41 is arranged between the tube tail support 42 and the liquid-conducting core rod 24, and the tube tail support 42 is used to support the top pressure spring 41. The tube tail support 42 does not prevent liquid from entering the lower core rod tube 4b, that is, the core rod tube (4a, 4b) and being adsorbed to the liquid-conducting core rod 24. Here, the liquid is the liquid in the base 100, that is, the liquid in the liquid storage chamber 11. Among them, the tube tail support 42 is provided with a support chamber 421 opening upward, one end of the top pressure spring 41 extends into the support chamber 421, and the other end is connected to the liquid guiding core rod 24, the lower core rod tube 4b is provided with a rod liquid inlet 40, and the tube tail support 42 is provided with a support member liquid inlet 422 connected to the rod liquid inlet 40. The liquid in the base 100 enters the support chamber 421 from the support member liquid inlet 422 of the tube tail support 42, and then enters the interior of the lower core rod tube 4b through the rod liquid inlet 40, so that the liquid in the base 100 can be adsorbed onto the liquid guiding core rod 24.

[0060] The present invention supports the lower end of the top pressure spring 41 through the tube tail support 42, and the tube tail support 42 is also the support carrier of the liquid-conducting core rod 24. Since the tube tail support 42 can be detachably installed on the tube tail of the lower core rod tube 4b, if the liquid-conducting core rod 24 needs to be repaired or replaced, the integrated module 200 is first disassembled, and then the tube tail support 42 is removed to take out the liquid-conducting core rod 24.

[0061] In order to improve the safety of the atomizing device of the present invention, the atomizing device of the present invention further comprises a metal sleeve 5 for liquid level sensing. The rod liquid inlet 40 is arranged at the lower end of the lower core rod tube 4b, and the rod liquid inlet 40 is used to allow the liquid in the base 100 to enter the core rod tube (4a, 4b) to be adsorbed by the liquid guide core rod 24. The metal sleeve 5 is sleeved on the outer side of the lower core rod tube 4b and is electrically connected to the main control circuit 23 in the integrated module 200. There is a spacing between the rod liquid inlet 40 and the metal sleeve 5. When the base 100 is filled with liquid and the liquid level is such that the liquid can enter the lower core rod tube 4b and be adsorbed onto the liquid guiding core rod 24, and at the same time can make the liquid contact with the metal sleeve 5, the metal sleeve 5, the liquid in the base 100, the liquid on the liquid guiding core rod 24 and the microporous atomizing sheet 22 form a signal communication path to realize the electrical signal conduction with the main control circuit 23. At this time, the microporous atomizing sheet 22 works normally; on the contrary, if the liquid level in the base 100 does not reach the bottom of the metal sleeve 5 or the liquid cannot enter the core rod tube (4a, 4b), that is, the resistance between the metal sleeve 5 and the liquid in the liquid storage chamber 11 increases sharply due to the spacing, and the loop current signal becomes very weak. At this time, the metal sleeve 5 and the microporous atomizing sheet 22 are almost broken, and the main control circuit 23 controls the microporous atomizing sheet 22 to stop working. It can be seen that the metal sleeve 5 is cleverly connected to the intermediate conductor of the microporous atomizing sheet 22 by using the liquid in the liquid storage chamber 11 and the liquid on the liquid guide core rod 24 as an electrical signal, thereby realizing the detection of whether the liquid level in the liquid storage chamber 11 has reached the set height, which can prevent the microporous atomizing sheet 22 from continuing to work without sufficient liquid, thereby protecting the atomizing equipment. In addition, if the liquid guide core rod 24 cannot conduct the liquid to the microporous atomizing sheet 22, a circuit is also formed between the metal sleeve 5 and the microporous atomizing sheet 22, and the microporous atomizing sheet 22 will also stop working.

[0062] In addition, the present invention sleeves the metal sleeve 5 on the outside of the lower core rod tube 4b, which is not only compact in structure, but also stable and reliable, and easy to install and manufacture; the metal sleeve 5 can also be used to protect the liquid-conducting core rod 24 and the lower core rod tube 4b from deformation or breakage due to external impact; the metal sleeve 5 and the lower core rod tube 4b cooperate with each other to improve the impact resistance.

[0063] The metal sleeve 5 can be positioned on the core rod tube (4a, 4b), on the module housing 21, or on the lower end cover 3, or can be positioned by other structures in the atomizing device. In this embodiment, the upper end of the metal sleeve 5 is positioned on the lower end cover 3. Specifically, the top of the metal sleeve 5 is provided with a wiring end 51 extending upward, and the lower end cover 3 is provided with a wiring end connecting hole (not shown in the drawings) for the wiring end 51 to pass upward into the upper part of the lower end cover 3. The wiring end 51 is sealed and connected to the lower end cover 3. The present invention provides a wiring end connecting hole for the wiring end 51 to pass through on the lower end cover 3, so that the metal sleeve 5 can be connected to the main control circuit 23 above the lower end cover 3. Due to the stability of the metal sleeve 5 sleeve structure, the metal sleeve 5 is not prone to shaking, so the wiring end 51 and the lower end cover 3 can maintain good sealing for a long time. For example, when the wiring end 51 and the wiring end connecting hole of the lower end cover 3 are sealed by glue, the sealing glue is not prone to cracks during long-term use to affect the sealing performance.

[0064] Furthermore, when the liquid level is lower than the metal sleeve 5, a water film will form on the surface of the metal sleeve 5, and this water film may bypass the lower core rod tube 4b and communicate with the liquid-conducting core rod 24, causing a false electrical signal conduction phenomenon. In order to reduce the probability of this phenomenon, the present invention also sets a detachable insulating sealing ring (not shown in the drawings) on the lower outer side of the lower core rod tube 4b, and the metal sleeve 5 stands on the insulating sealing ring. The lower outer side of the lower core rod tube 4b and the metal sleeve 5 form a sealed and insulated connection through the insulating sealing ring. In this way, when the liquid level is lower than the insulating sealing ring, the gap between the tube tail support 42 and the lower core rod tube 4b cannot enter the conductive liquid, and of course, the liquid-conducting core rod 24 and the metal sleeve 5 cannot achieve electrical signal conduction with the help of liquid. In another embodiment, the insulating sealing ring realizes the sealing among the tube tail support 42, the lower core rod tube 4b and the metal sleeve 5, and the insulating sealing ring is locked by the tube tail support 42, as described below.

[0065] Specifically, a detachable insulating sealing ring 43 is also mounted on the lower outer side of the lower core rod tube 4b, and the insulating sealing ring 43 includes a sealing ring upright portion 431 and a sealing ring edge portion 432 connected to the lower portion of the sealing ring upright portion 431 and extending radially outward. The metal sleeve 5 and the lower outer side of the lower core rod tube 4b are sealed by the sealing ring upright portion 431. The lower end of the metal sleeve 5 stands on the sealing ring edge portion 432. The tube tail support 42 is snap-connected to the lower core rod tube 4b and can squeeze the sealing ring edge portion 432 upward so that the sealing ring edge portion 432 is tightly fitted with the tube tail support 42, the lower core rod tube 4b, and the metal sleeve 5, respectively. The tube tail support 42 is an insulator. At this time, the insulating sealing ring 43 is used to achieve sealing between the tube tail support 42, the lower core rod tube 4b and the metal sleeve 5 to prevent liquid from entering the gap between the tube tail support 42 and the lower core rod tube 4b, so that the liquid signal in the gap connects the metal sleeve 5 and the liquid guiding core rod 24. In addition, the insulating sealing ring 43 is easy to install. During installation, the insulating sealing ring 43 is first put on the outside of the lower core rod tube 4b, and then the tube tail support 42 is buckled on the lower end of the lower core rod tube 4b to simultaneously squeeze and lock the insulating sealing ring 43 upward.

[0066] In addition, in order to warn the user that the liquid level in the liquid storage chamber 11 is lower than the normal use level, the present invention provides a liquid level indicator in the integrated module 200, and the liquid level indicator signal is connected to the main control circuit 23, and the main control circuit 23 is used to respond to the liquid level information provided by the metal sleeve 5 and control the liquid level indicator to emit a light indication signal. The liquid level indicator is located on the inner side of the module housing top wall 211, and the module housing top wall 211 is also used to allow the light emitted by the liquid level indicator to be transmitted. Among them, the liquid level indicator can be one or more of the one or more light-emitting lamps 832 on the key circuit board 83.

[0067] In order to increase the spray stroke of the mist and expand the range of humidification, the atomization device of the present invention also includes a blower 61, which is arranged in the inner cavity of the integrated module 200, that is, in the module shell 21. The blower 61 is controlled by the main control circuit 23. The module shell top wall 211 is also provided with a module shell air outlet 213. The module shell air outlet 213 is arranged on the side of the module shell mist hole 212. The module shell air outlet 213 is used to draw the wind blown by the blower 61 upward. The module housing air outlet 213 is used to lead the wind blown by the blower 61 upward, which defines that there is a wind connection relationship between the module housing air outlet 213 and the blower 61. In this embodiment, an exhaust duct is also provided in the inner cavity of the integrated module 200, and the exhaust duct connects the blower 61 and the module housing air outlet 213. The wind blown by the blower 61 is concentrated through the exhaust duct and led to the module housing air outlet 213, thereby increasing the wind force of the module housing air outlet 213 exhaust, so that the mist sprayed from the module housing mist hole 212 can be sprayed farther, wherein the exhaust duct is formed by the blower air outlet 6b, the air chamber cavity 65, and the air induction channel 71 described below being connected in sequence. In another embodiment, the exhaust duct can also be formed by other methods, such as directly setting a rib with an exhaust duct on the module housing 21. In another embodiment, the blower 61 may also be arranged around the module housing air outlet 213 so that the module housing air outlet 213 is directly used as the air outlet of the blower 61. The wire hole in the island portion 6 is also provided with a blower wire seal 611, and the blower wire seal 611 is used to seal the wire hole around the electric wire connected to the blower 61.

[0068] The present invention integrates the blower 61 for blowing air into the integrated module 200. When working, the microporous atomizing sheet 22 conducts the liquid below it into atomized liquid and then sprays it upward from the mist hole 212 of the module shell. At the same time, the module shell air outlet 213 arranged beside the module shell mist hole 212 draws out the wind blown out by the blower 61 upward. The wind drawn out from the module shell air outlet 213 will drive the mist sprayed from the side to a farther distance. When the mist is sprayed to a farther distance, it can not only expand the humidification space of the atomizing device, but also reduce the amount of mist gathered near the mist hole 212 of the module shell, thereby reducing the amount of mist entering the integrated module 200 and reducing the accumulation of droplets formed after the mist gathers on the top of the integrated module 200.

[0069] In order to improve the uniformity of the mist diffusion of the atomizing device, the module housing air outlet holes 213 are two and are arranged on the left and right sides of the module housing mist hole 212. The present invention simultaneously blows the sprayed mist upward through the module housing air outlet holes 213 on the left and right sides of the module housing mist hole 212, which can form a certain barrier to increase the distance of the mist spraying upward, and can also improve the uniformity of the mist diffusion. In other embodiments, the module housing air outlet holes 213 can also be provided with three, four, etc. uniformly arranged along the circumferential direction.

[0070] It should be noted that there is an inner shell space between the upper core rod tube 4a and the module shell 21, and the blower 61 and the main control circuit 23 are arranged in the inner shell space. The blower 61 is also arranged in the module shell 21 and is located above the lower end cover 3. The air duct seal 64, the intermediate mold frame 7, the key seal 81 and the key circuit board 83 described below are all arranged in the inner shell space. In the shell space, i.e., in the module housing 21, an island portion 6 is also provided. The island portion 6 is sleeved on the upper core rod tube 4a. The island portion 6 is also sleeved on the liquid guide core rod 24. An island portion sealing ring 66 for sealing is provided between the island portion 6 and the module housing 21. A battery cavity (not shown in the drawings) and a fan cavity 6a are also provided on the island portion 6. The fan cavity 6a and the battery cavity are arranged on the left and right. A battery 62 for providing driving power is provided in the battery cavity. The battery cavity is a cavity with a lower opening. The battery 62 is locked in the battery cavity by a battery gland 67. The blower 61 is provided in the fan cavity 6a. The integrated module 200 also includes a charging interface circuit board 63. The charging interface circuit board 63 is electrically connected to the battery 62 and is used to charge the battery 62 when the charging interface circuit board 63 is connected to an external power source. The module housing 21 is provided with a module housing charging hole 214 for exposing the charging interface. The module housing 21 is provided with an air inlet 215 , and the air inlet 215 is used to allow air outside the module housing 21 to enter the inner shell space, that is, the module housing 21 .

[0071] The battery 62 mainly provides the main control circuit 23 and the blower 61 with the required electrical energy. Since the atomizing device of the present invention has the battery 62, it can work normally even without an external power supply, which is convenient for users to carry and use. In addition, the present invention uses the island portion 6 as a carrier for the blower 61 and the battery 62, and the blower 61 and the battery 62 are integrated to facilitate the overall assembly of the integrated module 200, and the atomizing device reasonably utilizes the space inside the shell to increase the function of storing electrical energy.

[0072] Furthermore, an air duct sealing body 64 is also provided in the inner cavity of the integrated module 200 located above the island portion 6. The air duct sealing body 64 is sleeved on the liquid guide core rod 24, and the air duct sealing body 64 is also sleeved on the upper core rod tube 4a. A wind chamber cavity 65 is formed between the air duct sealing body 64 and the island portion 6. A blower air outlet 6b for connecting the blower 61 and the air chamber cavity 65 is provided on the island portion 6. The air chamber cavity 65 is connected to the module housing air outlet 213. The present invention forms an independent air chamber cavity 65 between the air duct sealing body 64 and the island portion 6. The wind blown by the blower 61 is concentratedly discharged to the module housing air outlet 213 through the independent air chamber cavity 65, thereby reducing the loss of wind during transmission, so that the mist sprayed from the mist hole 212 of the module housing is sprayed farther under greater wind power.

[0073] Furthermore, an intermediate mold frame 7 is also provided in the inner cavity of the integrated module 200 located above the air duct sealing body 64, and an air induction channel 71 connected to the air chamber cavity 65 is provided on the intermediate mold frame 7, and the air induction channel 71 is connected to the air outlet hole 213 of the module shell, and the microporous atomizing sheet 22 is installed under the intermediate mold frame 7 through a pressing plate 44, and the intermediate mold frame 7 is provided with a mold frame mist hole 72 connected to the mist hole 212 of the module shell. Among them, the blower 61 is arranged under the intermediate mold frame 7. The microporous atomizing sheet 22 is installed under the intermediate mold frame 7 through a pressing plate 44, which defines that the microporous atomizing sheet 22 is arranged under the intermediate mold frame 7 and is positioned by the pressing plate 44, and the pressing plate 44 is located at the top of the upper core rod tube 4a and the two are an integrated structure, and the pressing plate 44 is connected to the intermediate mold frame 7 by screws. The intermediate mold frame 7 is barrel-shaped and includes a mold frame top wall 7a and a mold frame side wall 7b. The mold frame mist holes 72 are arranged on the mold frame top wall 7a. The air duct sealing body 64 is located in the barrel cavity of the intermediate mold frame 7 and is clamped and fixed by the mold frame side wall 7b and the island portion 6. The intermediate mold frame 7 and the island portion 6 are supported on the lower end cover 3 and are pressed by the lower end cover 3 in the axial direction.

[0074] The internal components of the integrated module 200 of the present invention are integrated and installed through the middle mold frame 7, the island portion 6 and the lower end cover 3, and the middle mold frame 7 and the island portion 6 are directly axially positioned through the locking relationship between the lower end cover 3 and the module shell 21, which is easy to install and subsequently maintain.

[0075] In order to facilitate the use and observation of the user, the present invention designs the button 85 and the light 832 to be arranged upward while spraying the mist upward. Figure 6 and Figure 7Describe this part in detail.

[0076] The present invention further provides a module housing light-transmitting hole 216 and a module housing key hole 217 on the module housing top wall 211, and further provides a key sealing body 81 capable of transmitting light, a light guide column 82 and a key circuit board 83 in the module housing 21. The key circuit board 83 is located below the middle mold frame 7, and a control key contact 831 and a light-emitting lamp 832 are provided on the key circuit board 83. In this embodiment, the key circuit board 83, the light guide column 82 and the key sealing body 81 are located in the space above the lower end cover 3, the key circuit board 83 is located in the barrel cavity of the middle mold frame 7, and the key sealing body 81 is located above the mold frame top wall 7a. Among them, the key sealing body 81 capable of transmitting light defines that light can pass through the key sealing body 81.

[0077] The key seal 81 is arranged between the top wall 211 of the module housing and the middle mold frame 7, and a key seal mist hole 811 is provided on the key seal 81. The upper and lower sides of the hole peripheral wall of the key seal mist hole 811 are respectively sealed and connected with the hole peripheral wall of the module housing mist hole 212 and the hole peripheral wall of the mold frame mist hole 72, so that the mold frame mist hole 72, the key seal mist hole 811 and the module housing mist hole 212 are connected to form a demisting channel 80, and the demisting channel 80 is used to allow the mist from the microporous atomizing sheet 22 to pass through the mist hole 212. The mist vapor is sprayed upward from the mist exhaust channel 80. Accordingly, the module housing top wall 211, the key seal 81 and the middle mold frame 7 are respectively provided with air holes that allow the air blown by the blower 61 to pass through so that the air blown by the blower 61 can be blown out from the side of the module housing mist vapor hole 212. The air hole corresponding to the module housing top wall 211 is the module housing air outlet hole 213, the air hole corresponding to the key seal 81 is the key seal air hole 813, and the air hole corresponding to the middle mold frame 7 is the air induction channel 71. The key seal 81 is used to seal the internal space of the module housing 21 so that the water vapor outside the module housing 21 cannot pass through the module housing top wall 211 and enter the internal space of the module housing 21.

[0078] Among them, the upper and lower side surfaces of the hole circumferential wall of the key sealing body mist hole 811 are respectively sealed and connected with the hole circumferential wall of the module shell mist hole 212 and the hole circumferential wall of the mold frame mist hole 72, so that the mold frame mist hole 72, the key sealing body mist hole 811, and the module shell mist hole 212 are connected to form a demisting channel 80, and the demisting channel 80 is defined as a channel with sealed side walls. The mist generated by the microporous atomization sheet 22 cannot directly enter the space between the upper side of the key sealing body 81 and the lower side of the module shell top wall 211 through the demisting channel 80, nor can it directly enter the space between the lower side of the key sealing body 81 and the upper side of the intermediate mold frame 7 through the demisting channel 80.

[0079] The middle mold frame 7 is provided with a light guide column avoidance hole 73. In this embodiment, the light guide column avoidance hole 73 is provided on the mold frame top wall 7a. The light guide column 82 is inserted into the light guide column avoidance hole 73 to transmit the light of the light emitting lamp 832 located below the middle mold frame 7 to the key sealing body 81 located above the middle mold frame 7. The module housing light transmission hole 216 is located above the light guide column 82. The module housing light transmission hole 216 is used to allow the light transmitted by the light guide column 82 to pass through the key sealing body 81 and then be transmitted to the outside of the module housing 21. The light emitted by the light emitting lamp 832 on the key circuit board 83 passes through the light guide column 82 above it to be guided to the top of the middle mold frame 7, and then passes through the key sealing body 81 and continues to be emitted upward, and finally irradiated by the module housing light transmission hole 216. Among them, the key sealing body 81 can be provided with a light guide column 812 extending into the module housing light transmission hole 216 on its upper side. The light guide column 82 may be in direct contact with the light emitting lamp 832 , or a certain distance may be set between the two.

[0080] The middle mold frame 7 is also provided with a button leg avoidance hole 74. In this embodiment, the button leg avoidance hole 74 is arranged on the mold frame top wall 7a. The button sealing body 81 is also provided with a button leg 84 extending downward and extending into the button leg avoidance hole 74, and also includes a button 85. The button 85 passes through the module housing button hole 217 and is inserted into the button leg 84. The button 85 is used to touch the control button contact 831 on the button circuit board 83 located below the middle mold frame 7 with the help of the button leg 84 when the button 85 is pressed.

[0081] Among them, the key sealing body 81 is used to seal the internal space of the module shell 21 so that water vapor outside the module shell 21 cannot pass through the module shell top wall 211 and enter the internal space of the module shell 21. It is defined that the key sealing body 81 is made of a material with sealing properties, and is used to seal the module shell mist hole 212, module shell light-transmitting hole 216 and module shell key hole 217 on the module shell top wall 211 to prevent external water vapor from entering the internal space of the module shell 21 through the module shell mist hole 212, module shell light-transmitting hole 216 and module shell key hole 217. Firstly, the mist hole 212 of the module shell is sealed with the internal space of the module shell 21 through the wall body surrounded by the mist exhaust channel 80 sealed by the side wall and the microporous atomization sheet 22; secondly, the light guide column 82 is arranged below the key sealing body 81 and combined with the light-transmitting key sealing body 81 to illuminate the light from the light-transmitting hole 216 of the module shell, and at this time, the key sealing body 81 can seal the light-transmitting hole 216 of the module shell; thirdly, the key 85 is arranged above the key sealing body 81, and the key 85 touches the control key contact 831 on the key circuit board 83 located below the middle mold frame 7 through the key leg 84 of the key sealing body 81, and at this time, the key sealing body 81 can seal the key hole 217 of the module shell.

[0082] The atomizing device of the present invention centrally arranges the module housing mist hole 212 for spraying out mist, the module housing light-transmitting hole 216 for guiding out light, and the module housing button hole 217 for facilitating the up and down pressing of the button 85 on the module housing top wall 211. Since the upper surface of the module housing top wall 211 is arranged upward, when the atomizing device needs to be controlled by the button 85, the button 85 can be directly pressed downward. Since the force of pressing the button 85 is downward, the atomizing device will not fall under the force of this pressing, thereby improving the convenience and stability of the operation of the atomizing device. In addition, since the light generated by the light-emitting lamp 832 is irradiated upward by the module housing top wall 211, it is convenient to view the light-emitting state of the light-emitting lamp 832 while pressing the button 85 downward. For example, when different light display states represent different working modes, the user can directly observe whether the selected working mode is correct according to the light display state seen.

[0083] In addition, since the mist of the present invention is sprayed upward, droplets are easily accumulated on the top wall portion 211 of the module shell. In order to prevent the mist near the top wall portion 211 of the module shell and the droplets formed thereon from entering the inner cavity of the integrated module 200, the present invention realizes the internal and external sealing of the top wall portion 211 of the module shell by setting the button sealing body 81 and reasonably arranging the light guide column 82 and the button 85, so that the water vapor outside the module shell 21 cannot pass through the top wall portion 211 of the module shell and enter the internal space of the module shell 21.

[0084] In order to improve the aesthetics of the button 85 and the concentration of light transmission, the atomization device of the present invention further includes a button decoration plate 86 and an annular light-transmitting member 87 .

[0085] The button decorative plate 86 is arranged on the outside of the module housing top wall 211 and covers the button 85 so that the button 85 forms a hidden structure. The present invention hides the button 85 underneath the button decorative plate 86 to prevent the button 85 from being exposed, thereby improving the aesthetics of the top of the atomization device. In this embodiment, the button decorative plate 86 is made of black silicone material. Of course, the button decorative plate 86 does not prevent the microporous atomization sheet 22 from spraying mist, and the button decorative plate 86 is provided with a decorative plate mist hole 861.

[0086] The annular light-transmitting member 87 is annular and can transmit light. The inner edge of the annular light-transmitting member 87 is pressed on the outer edge of the key decorative plate 86. The annular light-transmitting member 87 covers the upper part of the module housing light-transmitting hole 216. The annular light-transmitting member 87 is used to conduct the light emitted from the module housing light-transmitting hole 216 outward. The light emitted from the module housing light-transmitting hole 216 can be emitted upward after passing through the annular light-transmitting member 87. The present invention arranges the annular light-transmitting member 87 above the module housing light-transmitting hole 216, so that the light generated by the light-emitting lamp 832 is finally irradiated upward by the top wall 211 of the module housing, so that the light can be irradiated upward, which is convenient for the user to observe the luminous state of the light-emitting lamp 832 when operating the key 85; in addition, the distance of light transmission upward is shorter than that of light transmission to the side of the module housing 21, which can reduce the loss of light. Of course, the annular light-transmitting member 87 does not hinder the exhaust of the blower 61 , and a light-transmitting member air hole 871 is provided on the annular light-transmitting member 87 .

[0087] Furthermore, it also includes a barrel-shaped outer cover 25, the outer cover 25 includes a cover side wall 251 and a cover top wall 252, the cover top wall 252 is provided with a top wall hole 253, the outer cover 25 is sleeved on the module housing 21, and from the top view, the button 85 and the module housing light-transmitting hole 216 are located within the range defined by the top wall hole 253, so that from the position of the top wall hole 253, not only can the button 85 be touched, but also the light transmitted by the light guide column 82 can be transmitted. The present invention sleeves the outer cover 25 on the module housing 21, and during production, a relatively high-end material can be selected for the outer cover 25 to improve the overall aesthetics of the atomizing device. In addition, the outer cover 25 limits the light emission surface within the range defined by the top wall hole 253, so that the light can only be irradiated upwards. At this time, since the light is concentrated upward, the atomizing device of the present invention can be used as a night light.

[0088] In order to prevent the air pressure in the liquid storage chamber 11 from being too high and causing the liquid to leak out of the microporous atomizing sheet 22 or being too low and affecting the speed and amount of the liquid crawling on the liquid guiding core rod 24, the present invention further provides an air hole 91 on the atomizing device above the space above the liquid level of the liquid storage chamber 11. The space above the liquid level of the liquid storage chamber 11 is connected to the external space through the air hole 91, and a spacer air film 92 is provided on the connecting channel connecting the space above the liquid level of the liquid storage chamber 11 and the external space. The spacer air film 92 is used to allow air to pass through but not allow the liquid in the liquid storage chamber 11 to flow through. The structure of providing a spacer air film 92 on the connecting channel here can also be applied to any other atomizing device that uses a microporous atomizing sheet 22 to atomize liquid and a liquid guiding core rod 24 to conduct liquid, and is not limited to the base 100 and integrated module 200 type atomizing device used in this embodiment. For example, it can be applied to an atomization device in which the liquid storage chamber 11, the microporous atomization sheet 22 and the liquid guiding core rod 24 are integrated at the top, and other structures such as the blower 61, the main control circuit 23, etc. are arranged at the bottom; or an atomization device using other arrangements or application scenarios.

[0089] It should be noted that during the installation and use of the atomization equipment, a higher air pressure may be formed in the liquid storage chamber 11. At this time, the liquid in the liquid storage chamber 11 will crawl to the microporous atomization sheet 22 due to the increased pressure when the microporous atomization sheet 22 is not working and be squeezed out by the high air pressure. The leaked liquid will form water accumulation on the outside of the microporous atomization sheet 22 and pollute the environment; on the contrary, if the air pressure in the space above the liquid level of the liquid storage chamber 11 is too low, the amount of liquid crawling out along the liquid guiding core rod 24 will be greatly reduced and the speed will be greatly reduced, thereby affecting the amount and speed of the liquid crawling on the liquid guiding core rod 24. The present invention realizes the connection between the liquid storage chamber 11 and the external space through the air hole 91, and a spacer air film 92 is provided on the connecting channel connecting the liquid storage chamber 11 and the external space. The air in the liquid storage chamber 11 can be connected with the air in the external space through the spacer air film 92 on the connecting channel, so that the air pressure in the space above the liquid level of the liquid storage chamber 11 will not be too high or too low, and the spacer air film 92 has the performance of preventing the liquid from flowing through, so the liquid in the liquid storage chamber 11 cannot flow out from the spacer air film 92. It can be seen that the atomizing device of the present invention can not only solve the problem of self-pressure maintenance due to the air pressure in the space above the liquid level of the liquid storage chamber 11 being too high or too low, but also prevent the liquid in the liquid storage chamber 11 from flowing out from the spacer air film 92. Among them, the atomizing device of the present invention can select a waterproof and breathable membrane with two-way air permeability or a waterproof and breathable membrane with one-way air permeability from the inside to the outside.

Among them, the fixing frame 93 can be fixed to the connecting channel by bonding, snapping or screwing. In addition, the fixing frame 93 and the spacer air membrane 92 can directly adopt the waterproof breathable valve in the prior art. The present invention can select but is not limited to using the outer shell wall of the one-way valve in the prior art as the fixing frame 93, so that the spacer air membrane 92 is combined with the one-way valve to form a structure with a one-way air permeability function.

[0092] As an implementation scheme of the installation position of the above-mentioned spacer air film 92, the spacer air film 92 is arranged on the air hole 91. The air hole 91 serves as the end position of the connecting channel, which is convenient for installing the spacer air film 92. In other embodiments, the spacer air film 92 can also be arranged at the other end of the connecting channel away from the air hole 91, or even at a certain position in the middle of the connecting channel. In addition, the part forming the connecting channel can be the gap formed between the various components of the atomization device, can be a hole provided in a certain component of the atomization device, or can be an external ventilation duct.

[0093] It should be noted that, in the present embodiment, the lower end cover 3 is a split structure including a separately arranged partition cover portion 3a and a ring-shaped locking ring portion 3b located below the partition cover portion 3a, wherein the locking ring portion 3b and the base 100 are sealed via a first locking ring seal 33, and the partition cover portion 3a and the locking ring portion 3b are sealed via a second locking ring seal 34. Furthermore, since the partition cover portion 3a and the module housing 21 are sealed via the first cover seal 31, the lower end cover 3 between the first cover seal 31 and the first locking ring seal 33 and the module housing 21 and the base 100 are all in a sealed state. The air hole 91 is arranged on the wall of the lower end cover 3 between the first cover sealing ring 31 and the first locking ring sealing ring 33. There is a flow gap between the module housing 21 and the base 100. The air hole 91 is connected to the flow gap. The lower chamber 90 above the liquid level is connected to the external space through the air hole 91 and the flow gap. The present invention arranges the air hole 91 on the lower end cover 3, and the lower end cover 3 is hidden in the module housing 21 and the base 100. At this time, the air hole 91 and the flow gap and the part connecting the two form a connecting channel connecting the liquid storage chamber 11 and the external space, which can improve the overall aesthetics of the atomization device of the present invention.

[0094] In another embodiment, the lower end cover 3 is an integrated structure, in which the upper wall of the lower end cover 3 and the module housing 21 are sealed via a first cover sealing ring 31, and the lower wall of the lower end cover 3 and the base 100 are sealed via a first locking ring sealing ring 33.
