Description

Technical Field

[0001] The present invention relates to the field of atomizing equipment, and in particular to an atomizing equipment for spraying mist upwards. The atomizing equipment realizes the spraying of mist upwards, and at the same time, the buttons and the light-emitting lamp are designed to be arranged upwards, so as to facilitate the use and observation of the atomizing equipment. The atomizing equipment can be a desktop atomizer or a mobile vehicle-mounted atomizer. The atomizer can be used for atomizing 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] When the atomizing device adopts a microporous atomizing sheet, the mist atomized by the microporous atomizing sheet is generally sprayed upward, and the control buttons for controlling the operation of the atomizing device and the parts showing light are generally arranged on the side wall of the atomizing device. For example, the Chinese utility model patent with publication number CN207190736U discloses a vehicle-mounted humidifier water tank connection structure, including a water tank assembly 10 and a head assembly 20. The head assembly 20 is arranged above the water tank assembly 10. The head assembly 20 is provided with an atomizing device and a control circuit. The water tank assembly 10 is connected to the atomizing device through a water absorption core rod 6. The atomizing device is electrically connected to the control circuit. A cup cover 5 is provided at the bottom of the head assembly 20. The bottom of the water tank assembly 10 is closed, and the top of the water tank assembly 10 is open to form a water inlet. The head assembly 20 is plugged into the water tank assembly 10, and the cup cover 5 is arranged on the water inlet. The cup cover 5 is sealed with the water inlet, and the water absorption core rod 6 extends into the water tank assembly 10 through the water inlet. The control circuit includes a main control board 101 and a control board 60. The main control board 101 is fixed on the cup cover 5 by screws, and the screws penetrate from the bottom surface of the cup cover 5. The bottom surface of the cup cover 5 is also provided with an inner cover 54, which is made of silicone and has a sealing effect. A positioning column 541 is provided on the top surface of the inner cover 54, and an O-type sealing ring 542 is sleeved on the outer periphery of the positioning column 541. The positioning column 541 is plugged into the screw connection position of the cup cover 5 and sealed by the O-type sealing ring 542 to prevent water from entering the installation position of the main control board 101 from the screw connection position. The control board 60 is vertically arranged at the bottom of the upper end cover 102, and an indicator light and a control switch are arranged on the control board 60. A control panel is arranged at the upper end of the outer sleeve 2 corresponding to the control board 60, and a light-transmitting hole 25 is arranged on the control panel corresponding to the indicator light and a button 24 is arranged on the control panel corresponding to the control switch. In this disclosed technical solution, the mist is sprayed upward from the top of the head assembly 20, and the control panel 60 is vertically arranged at the bottom of the upper end cover 102, wherein the indicator light and control switch arranged on the control panel 60 are facing the side direction of the head assembly 20.

[0004] The main problem with this product is that, firstly, since the button 24 is arranged on the side of the head assembly 20, the humidifier may shake or even fall down under the pressure from the side during use, so most users generally choose to hold the humidifier by hand or press it in their hands. It can be seen that this structure brings great inconvenience to the user and affects the user experience; secondly, when the button 24 and the indicator light are arranged toward the side of the head assembly 20, especially when the humidifier is placed in a lower position, the user even needs to bend down to operate the corresponding button, or pick up the humidifier to operate, and the indicator light arranged on the side is not convenient for the user to watch; in addition, if the indicator light emits light toward the side, it is not convenient for the user to watch the light state of the indicator light when the user is on other sides of the head assembly 20. Summary of the invention

[0005] The technical problem to be solved by the present invention is also to provide an atomization device that sprays mist upwards, which not only makes it convenient for users to operate the buttons, but also makes it convenient to simultaneously observe the luminous state of the luminous lamp indicating the operation when operating the buttons, which can greatly improve the user's pleasure of use.

[0006] In view of the technical problems raised above, the present invention discloses an atomizing device for spraying mist upward, comprising a base, on which a liquid storage cavity with an open opening facing upward is arranged, and the liquid storage cavity is used to store liquid for atomization; and further comprising an integrated module arranged on the base, the integrated module comprising a module shell in a barrel shape, the module shell comprising at least one module shell top wall portion with an outer surface arranged upward, a microporous atomizing sheet and a liquid guide core rod being arranged in the module shell, a module shell mist hole being arranged on the module shell top wall portion, the module shell mist hole being used to allow the mist atomized by the microporous atomizing sheet to be sprayed upward from the module shell mist hole, and the liquid guide core rod being used to allow the liquid in the liquid storage cavity to crawl onto the microporous atomizing sheet;

[0007] The module housing top wall is also provided with a module housing light-transmitting hole and a module housing key hole. A light-transmitting key sealing body, a light-guiding column, an intermediate mold frame and a key circuit board are provided in the module housing. The key circuit board is located below the intermediate mold frame. Control key contacts and a light-emitting lamp are provided on the key circuit board. The microporous atomizing sheet is installed below the intermediate mold frame through a pressing plate.

[0008] The middle mold frame is provided with a mold frame mist hole, the key seal body is provided with a key seal body mist hole, the key seal body is arranged between the top wall of the module shell and the middle mold frame, and the upper and lower side surfaces of the hole peripheral wall of the key seal body mist hole are respectively sealed and connected with the hole peripheral wall of the module shell mist hole and the hole peripheral wall of the mold frame mist hole, so that the mold frame mist hole, the key seal body mist hole and the module shell mist hole are connected to form a mist exhaust channel, and the mist exhaust channel is used to allow the mist atomized by the microporous atomization sheet to be sprayed upward from the mist exhaust channel, and the key seal body is used to seal the internal space of the module shell so that the water vapor outside the module shell cannot pass through the top wall of the module shell and enter the internal space of the module shell;

[0009] The middle mold frame is provided with a light guide column avoidance hole, the light guide column is inserted into the light guide column avoidance hole to transmit the light of the light emitting lamp located below the middle mold frame to the key sealing body located above the middle mold frame, the module housing light transmission hole is located above the light guide column, and the module housing light transmission hole is used to allow the light transmitted by the light guide column to pass through the key sealing body and then be transmitted to the outside of the module housing;

[0010] The middle mold frame is also provided with a button leg avoidance hole, and the button sealing body is also provided with a button leg extending downward and extending into the button leg avoidance hole, and also includes a button, which passes through the button hole of the module housing and is inserted into the button leg. The button is used to touch the control button contact on the key circuit board located below the middle mold frame with the help of the button leg when the button is pressed.

[0011] In which, the integrated module is arranged on the base, and it is defined that one or several components in the integrated module are connected to the base. For example, when the base is a barrel-shaped structure with an open lower part, the integrated module can be connected to the upper opening of the base through the lower end of the module shell, and the integrated module can also be connected to the base through other components in the integrated module.

[0012] Wherein, the integrated module includes a module shell in a barrel shape, which defines that the module shell has a barrel cavity, and the top wall of the module shell is a part of the side wall forming the barrel cavity; the inside of the module shell refers to the inside of the barrel cavity of the module shell.

[0013] The microporous atomizing sheet has an atomizing hole, and the microporous atomizing sheet is generally connected to a driving circuit, and the driving circuit is used to drive the microporous atomizing sheet to vibrate at a high frequency, so that the liquid inside the microporous atomizing sheet is driven by the high-frequency vibrating microporous atomizing sheet to spray outward through the atomizing hole, and the liquid will form droplets with smaller particle size while being forced to pass through the atomizing hole, thereby forming an atomization effect on the outside of the microporous atomizing sheet, thereby humidifying the nearby air. The driving circuit can be set in the main control circuit described below.

[0014] Wherein, the microporous atomizing sheet is installed under the intermediate mold frame through a pressing plate, which defines that the microporous atomizing sheet is arranged under the intermediate mold frame and is positioned by the pressing plate. At this time, the intermediate mold frame, the key sealing body and the top wall of the module shell are arranged in sequence from bottom to top above the microporous atomizing sheet. Wherein, the upper and lower sides of the hole peripheral wall of the mist hole of the key sealing body are respectively sealed and connected with the hole peripheral wall of the mist hole of the module shell and the hole peripheral wall of the mist hole of the mold frame, so that the mist hole of the mold frame, the mist hole of the key sealing body and the mist hole of the module shell are connected to form a demisting channel, which defines that the demisting channel is a channel with side wall seals, and the mist generated by the microporous atomizing sheet cannot directly enter the space between the upper side of the key sealing body and the lower side of the top wall of the module shell through the demisting channel, nor can it directly enter the space between the lower side of the key sealing body and the upper side of the intermediate mold frame through the demisting channel.

[0015] The liquid-conducting core rod is used to allow the liquid in the liquid storage chamber to crawl onto the microporous atomizing sheet. The liquid-conducting core rod is made of a material that has a capillary effect with the liquid in the liquid storage chamber so that the liquid is conducted along the liquid-conducting core rod. The top of the liquid-conducting core rod is generally in contact with the bottom of the microporous atomizing sheet, and the lower end extends into the liquid storage chamber of the base. When the amount of liquid in the liquid storage chamber is sufficient, the liquid in the liquid storage chamber crawls upward along the liquid-conducting core rod to the lower surface of the microporous atomizing sheet under the capillary action of the liquid-conducting core rod, thereby achieving the purpose of supplying the microporous atomizing sheet with liquid for atomization through the liquid-conducting core rod. The liquid-conducting core rod can be a liquid-conducting cotton strip.

[0016] Wherein, the module housing includes at least one module housing top wall portion with an outer surface arranged upward, and defines a module housing top wall portion for setting the module housing mist hole, the module housing light-transmitting hole and the module housing button hole relative to the horizontal plane, 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 from the module housing mist hole arranged thereon can be sprayed vertically or obliquely upward, the light transmitted from the module housing light-transmitting hole arranged thereon can be irradiated vertically or obliquely upward, and the button passing through the module housing button hole thereon can be arranged vertically or obliquely upward. It can be seen that the present invention integrates the module housing mist hole, the module housing light-transmitting hole and the module housing button hole through the module housing top wall portion with the outer surface arranged upward, and can simultaneously realize the mist spraying upward, the light irradiating upward and the button being arranged upward.

[0017] The light-transmitting key seal defines that light can pass through the key seal. The light generated by the light-emitting lamp on the key circuit board is guided to the top of the intermediate mold frame through the light-guiding column above it, and then continues to irradiate upward after passing through the key seal, and finally irradiates out through the light-transmitting hole of the module shell. The key seal can be provided with a light-guiding column extending into the light-transmitting hole of the module shell on its upper side. The light-guiding column can be in direct contact with the light-emitting lamp, or a certain distance can be set between the two.

[0018] Wherein, the button sealing body is also provided with a button leg extending downward and extending into the button leg avoidance hole, and it is defined that the button leg is inserted into the button leg avoidance hole from the upper part of the middle mold frame. Wherein, the button is used to touch the control button contact on the button circuit board located below the middle mold frame with the help of the button leg when the button is pressed, and it is defined that the button leg faces the control button contact on the button circuit board. At this time, the button, button leg and control button contact are arranged in sequence from top to bottom. When the button needs to be controlled, the button is pressed downward, and the button drives the button leg to move downward together until the button leg pushes the control button contact downward to be triggered. When the button is in an unpressed state, the button leg can be in direct contact with the control button contact, or a certain distance can be set between the two.

[0019] Among them, the key sealing body is used to seal the internal space of the module shell so that water vapor outside the module shell cannot pass through the top wall of the module shell and enter the internal space of the module shell. It is defined that the key sealing body is made of a material with sealing properties, and is used to seal the module shell mist holes, module shell light-transmitting holes and module shell key holes on the top wall of the module shell to prevent external water vapor from entering the internal space of the module shell through the module shell mist holes, module shell light-transmitting holes and module shell key holes. First, the mist holes of the module shell are sealed with the internal space of the module shell through the mist exhaust channel sealed by the side wall and the wall body surrounded by the microporous atomization sheet; second, the light guide column is arranged below the key sealing body and combined with the light-transmitting key sealing body to illuminate the light from the light-transmitting hole of the module shell, and at this time, the key sealing body can seal the light-transmitting hole of the module shell; third, the key is arranged above the key sealing body, and the key touches the control key contact on the key circuit board located below the middle mold frame through the key leg of the key sealing body, and at this time, the key sealing body can seal the key hole of the module shell.

[0020] Among them, the control button contact is a switch or signal sensor, which is used to transmit operation signals such as power on, power off, acceleration and deceleration to the main control circuit to express the user's intention. It is a human-computer dialogue device. The main control circuit controls the microporous atomization sheet and the light-emitting lamp according to the received operation signal. For example, the control button contact is provided with two power-on button contacts and power-off button contacts. In the initial state, when the power-on button contact is pressed, the main control circuit controls the microporous atomization sheet and the light-emitting lamp to work. When the atomization device needs to stop working, it only needs to press the power-off button contact. For another example, the control button contact is provided with two contacts, namely a power button contact and a light button contact. In the initial state, when the power button contact is pressed, the main control circuit controls the microporous atomization sheet and the light lamp to work, and when the power button contact is pressed again, the main control circuit controls the microporous atomization sheet and the light lamp to stop working; in the initial state, when the light button contact is pressed, the main control circuit only controls the light lamp to work, thereby providing a light source, for example, it can be used as a night light. When the light button contact is pressed multiple times, the light emitted by the light lamp displays different states, such as different colors, different flashing forms, etc., which are not introduced one by one here.

[0021] According to the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. First, the present invention realizes the upward spraying of mist by setting the module housing mist hole on the top wall of the module housing; second, the present invention transmits light upward through the light guide column located above the illuminant, and the light transmitted by the light guide column passes through the key sealing body and then transmits to the outside of the module housing, so that the user can see the light transmitted by the light guide column in the up and down direction; third, the present invention enables the key to be pressed up and down to touch the control key contact below through the module housing key hole and the key leg on the key sealing body. It can be seen that the present invention centrally arranges the module housing mist hole for spraying mist, the module housing light-transmitting hole for guiding light, and the module housing key hole for facilitating the up and down pressing of the key on the top wall of the module housing. Since the upper surface of the module housing top wall is arranged upward, when the atomizing device needs to be controlled by the key, the key can be directly pressed downward. Since the force of pressing the key is downward, the atomizing device will not fall under the force of this pressing, thereby improving the convenience of operation of the atomizing device. In addition, since the light generated by the light lamp is irradiated upward from the top wall of the module shell, it is convenient to observe the lighting state of the light lamp while pressing the button downward. For example, when different light display states represent different working modes, the user can directly observe whether the selected working mode is correct based on the light display state seen.

[0023] 2. Since the mist of the present invention is sprayed upward, mist droplets are easily accumulated on the top wall of the module shell. In order to prevent the mist near the top wall of the module shell and the mist droplets formed thereon from entering the inner cavity of the integrated module, the present invention realizes the internal and external sealing of the top wall of the module shell by providing the button sealing body and reasonably arranging the light guide column and the button, so that the water vapor outside the module shell cannot pass through the top wall of the module shell and enter the internal space of the module shell.

[0024] In order to improve the aesthetics of the button, a further technical solution may also include a button decorative plate, which is arranged on the outside of the top wall of the module housing and covers the button so that the button forms a hidden structure. The present invention hides the button underneath the button decorative plate to prevent the button from being exposed, thereby improving the aesthetics of the top of the atomizing device. The button decorative plate may be made of, but not limited to, black silicone material.

[0025] A further technical solution may also include an annular light-transmitting member that is annular and can transmit light, the inner edge of which is pressed on the outer edge of the key decorative plate, the annular light-transmitting member covers the light-transmitting hole of the module housing, and is used to conduct the light guided out of the light-transmitting hole of the module housing to the outside. The inner edge of the annular light-transmitting member is pressed on the outer edge of the key decorative plate, which defines that the key decorative plate is positioned by the annular light-transmitting member.

[0026] Among them, the annular light-transmitting member capable of transmitting light is defined as being made of a light-transmitting material. The light emitted by the light-transmitting hole of the module housing can be emitted upward after passing through the annular light-transmitting member. The present invention arranges the annular light-transmitting member above the light-transmitting hole of the module housing, so that the light generated by the light-emitting lamp is finally irradiated upward from the top wall of the module housing, and the light can be irradiated upward, which is convenient for the user to observe the luminous state of the light-emitting lamp when operating the button; in addition, the distance of light transmission upward is shorter than that of light transmission to the side of the module housing, which can reduce the loss of light.

[0027] A further technical solution may also include a barrel-shaped outer cover, the outer cover includes a cover side wall and a cover top wall, the cover top wall is provided with a top wall hole, the outer cover is sleeved on the module housing, and from a top view, the button and the light-transmitting hole of the module housing are located within the range defined by the top wall hole, so that from the position of the top wall hole, not only the button can be touched, but also the light transmitted by the light guide column can be conducted. Wherein, the button can be touched from the position of the top wall hole, and touching the button here means touching the button through contact between the button decorative panels. The present invention sleeves the outer cover on the module housing, and during production, a relatively high-end material can be selected for the outer cover to improve the overall aesthetics of the atomizing device. In addition, the outer cover limits the light emission surface to the range defined by the top wall hole, so that the light can only be irradiated upward. At this time, since the light is concentrated upward, the atomizing device of the present invention can be used as a night light.

[0028] A further technical solution may be that the intermediate mold frame is barrel-shaped and includes a mold frame top wall and a mold frame side wall, the mold frame mist holes, button leg avoidance holes and light guide column avoidance holes are arranged on the mold frame top wall, the button circuit board is located in the barrel cavity of the intermediate mold frame, the button sealing body is located above the mold frame top wall, and the microporous atomization sheet is installed to the bottom of the mold frame top wall through a pressing plate. The present invention sets the intermediate mold frame into a barrel-shaped structure, which is convenient for the layout of the button circuit board and the microporous atomization sheet, wherein the button circuit board and the microporous atomization sheet can be fixed in the intermediate mold frame and then connected to the intermediate mold frame as a whole, which is convenient for subsequent integrated installation. In addition, the top wall of the mold frame can press the button sealing body, so that the top wall of the module housing, the button sealing body and the top wall of the mold frame are tightly attached to position the button sealing body. Of course, the intermediate mold frame described in the present invention may also adopt other structures, and the button leg avoidance hole and the light guide column avoidance hole are not necessarily independent holes, as long as the button and the light guide column can be installed while the button sealing body plays a sealing role.

[0029] A further technical solution may be that a lower end cover is further provided on the inner lower part of the module shell, the key circuit board, the light guide column and the key sealing body are located in the space above the lower end cover, an upper core rod tube is provided in the space above the lower end cover, the upper section of the liquid guiding core rod is inserted into the upper core rod tube, and the lower section of the liquid guiding core rod is provided below the lower end cover and extends downward; a first cover sealing ring is provided between the module shell and the lower end cover, and the first cover sealing ring is used to prevent the liquid in the liquid storage chamber from penetrating into the space above the lower end cover from the gap between the module shell and the lower end cover.

[0030] Among them, a lower end cover is also arranged at the lower inner part of the module shell, which defines that the lower end cover is arranged in the barrel cavity of the module shell and close to the lower end of the module shell, and the module shell and the lower end cover form the inner cavity of the integrated module, and the key circuit board, the light guide column and the key sealing body are arranged in this inner cavity, and the liquid guiding core rod extends downward from the inner cavity of the integrated module to the outer cavity of the integrated module.

[0031] Among them, the upper section of the liquid-conducting core rod is wrapped in the upper core rod tube, which can not only protect the liquid-conducting core rod from damage by the surrounding environment, but also ensure that the inner cavity of the integrated module outside the upper core rod tube is protected from erosion by the liquid on the liquid-conducting core rod, thereby improving the safety and service life of the electrical components in the integrated module. In addition, the wrapped liquid-conducting core rod 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.

[0032] The upper core rod tube and the lower end cover may be an integrated structure or a split, detachable connection structure.

[0033] The present invention isolates the inner cavity of the integrated module from the liquid storage cavity up and down through the lower end cover, and a first cover sealing ring is provided between the module housing and the lower end cover. When the atomizing device is tilted at a certain angle or even tipped over, the first cover sealing ring can prevent the liquid in the liquid storage cavity from penetrating from the gap between the module housing and the lower end cover into the space above the lower end cover, thereby improving the safety of the electrical components in the inner cavity of the integrated module.

[0034] A further technical solution may be that a second cover sealing ring is arranged between the upper core rod tube and the lower end cover, and a sealed connection is achieved through the second cover sealing ring. The present invention improves the sealing performance between the upper core rod tube and the lower end cover through the second cover sealing ring, and can prevent the liquid in the liquid storage cavity from flowing into the inner cavity of the integrated module through the gap between the outer wall of the upper core rod tube and the lower end cover.

[0035] A further technical solution may also include a lower core rod tube connected to the lower end cover, the lower core rod tube extending downward, the lower section of the liquid-conducting core rod inserted into the lower core rod tube, and the lower core rod tube does not prevent the liquid in the liquid storage chamber from contacting the lower section of the liquid-conducting core rod.

[0036] Among them, the lower core rod tube does not hinder the liquid in the liquid storage chamber from contacting the lower section of the liquid guiding core rod, and defines that the area where the lower core rod tube contacts the liquid in the liquid storage chamber is not a completely closed structure. For example, an inlet channel for liquid circulation is provided on the bottom wall and / or side wall of the lower part of the lower core rod tube, so that the liquid in the liquid storage chamber outside the lower core rod tube can enter the inner cavity of the lower core rod tube through this channel, thereby ensuring that the liquid guiding core rod can contact the liquid in the liquid storage chamber.

[0037] The lower mandrel tube can be integrally connected to the lower end cover or detachably connected to the lower end cover. The lower mandrel tube can protect the lower section of the liquid-conducting mandrel and facilitate the installation of the liquid-conducting mandrel tube. For details, please refer to the following description.

[0038] In order to ensure that the liquid-conducting core rod and the microporous atomizing sheet always maintain a reliable contact state, 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.

[0039] The present invention uses the top pressure spring to always subject the liquid-conducting core rod to an upward spring force, and the liquid-conducting core rod will be in contact with 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 top 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 lower 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 take out the liquid-conducting core rod. Of course, the tube tail support will not prevent the liquid in the liquid storage chamber from contacting the lower section of the liquid-conducting core rod. For example, a channel for circulating the liquid inside and outside the lower core rod tube can be provided on the tube tail support.

[0040] In order to increase the spray distance of the mist, a further technical solution may also include a blower, which is arranged in the module shell and located below the middle mold frame. The top wall of the module shell, the button sealing body and the middle mold frame are respectively provided with air holes for allowing the wind blown by the blower to pass through, so that the wind blown by the blower can be blown out from the side of the mist hole of the module shell.

[0041] Among them, the top wall of the module shell, the key sealing body and the middle mold frame are respectively provided with air holes that allow the air blown by the blower to pass through so that the air blown by the blower can be blown out from the side of the mist hole of the module shell, and the air holes corresponding to the top wall of the module shell are defined to be located on the side of the mist hole of the module shell. At this time, the air blown by the blower is located on the side of the mist sprayed from the mist hole of the module shell, and both face upward. When working, the wind discharged from the air holes corresponding to the top wall of the module shell will drive the mist sprayed from the side to be sprayed 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 top wall of the module shell, thereby reducing the amount of mist entering the integrated module and reducing the droplets formed after the mist gathers and accumulates on the top of the integrated module.

[0042] Since the present invention has the above characteristics and advantages, it can be used in liquid microporous atomization equipment such as humidifiers, aromatherapy machines, and medicine atomizers. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Combine the following Figures 1 to 7 The structure of the atomization equipment using the technical solution of the present invention is further described.

[0051] like Figure 1 and Figure 2 As 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] like Figure 3 and Figure 4 As 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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 .

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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 .

[0091] 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.

[0092] 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 .

[0093] 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.

[0094] 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.

[0095] 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.

[0096] In this embodiment, the liquid storage chamber 11 is arranged on the base 100, and the integrated module 200 is arranged on the base 100. At this time, a lower chamber 90 is enclosed between the integrated module 200 and the base 100, and the air hole 91 is arranged on the cavity wall of the lower chamber 90 located above the liquid level of the lower chamber 90, so that the space above the liquid level of the lower chamber 90 is connected with the external space through the air hole 91, and the spacer air film 92 is arranged on the connecting channel connecting the space above the liquid level of the lower chamber 90 and the external space.

[0097] Furthermore, it also includes a fixing frame 93, and the spacer air membrane 92 is arranged on the fixing frame 93, and the fixing frame 93 is installed on the connecting channel. The present invention uses the fixing frame 93 as an installation carrier of the above-mentioned spacer air membrane 92, and installs the spacer air membrane 92 on the connecting channel through this installation carrier, thereby improving the convenience of installing the spacer air membrane 92. 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.

[0098] 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.

[0099] 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.

[0100] 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. 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, a flow gap is provided between the module housing 21 and the base 100, the air hole 91 is connected to the flow gap, and the lower chamber 90 above the liquid level is connected to the external space via the air hole 91 and the flow gap.

[0101] In other embodiments, the spacer air membrane 92 may also be disposed at the flow gap formed between the module housing 21 and the base 100 .

[0102] Furthermore, the lower part of the module housing 21 is buckled and connected with the upper part of the base 100 through a stopper structure. The buckling connection between the module housing 21 and the base 100 using the stopper structure is not only simple in installation, but also convenient for forming a flow gap between the module housing 21 and the base 100 that is connected with the air hole 91.
