Through the above setting, the size of the cover piece can be reduced, the contact area between the cover piece and the liquid is reduced, the adhesive force generated after the cover piece contacts the liquid is reduced, and therefore, the amplitude of the cover piece turned up under the action of the air pressure difference can be increased, so that the air exchange effect is enhanced.

Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an umbrella-shaped valve plate, a gas exchange liquid-blocking valve, and an electronic atomization device. Background Technology

[0002] The working principle of electronic atomizing devices is to atomize and output liquid through an atomizing core or atomizing nozzle. Electronic atomizing devices have a liquid storage chamber and a ventilation hole that connects the liquid storage chamber to the external environment. A valve plate is installed at the ventilation hole. Specifically, the valve plate includes a valve handle and a cover plate. The valve handle is installed on the electronic atomizing device, and the cover plate covers the ventilation hole. Under the action of the air pressure difference inside and outside the liquid storage chamber, the cover plate can open the ventilation hole to allow air exchange.

[0003] The defects in the above-mentioned prior art are: since the ventilation hole and the liquid storage chamber are connected, the liquid will spread to the corresponding position between the cover plate and the electronic atomizing device. After the cover plate comes into contact with the liquid, it is easy to generate adhesive force, which makes the cover plate flip up only slightly under the action of air pressure difference, resulting in poor ventilation effect. Therefore, it is urgent to improve it. Utility Model Content

[0004] Therefore, it is necessary to provide an umbrella-shaped valve plate, a gas exchange liquid-blocking valve, and an electronic atomizing device to address the above problems, aiming to increase the extent to which the cover plate flips up under the action of air pressure difference, so as to enhance the ventilation effect.

[0005] The embodiments of this application achieve the above objectives through the following technical solutions.

[0006] This application provides an umbrella-shaped valve plate, which includes a valve handle and a cover plate connected to each other. The cover plate is elongated and the ratio L / W of the length L of the cover plate to the width W of the cover plate satisfies: 1.5≤L / W≤3.5.

[0007] In one embodiment, the length L of the cover sheet satisfies: 4.5mm ≤ L ≤ 7mm; and / or, the width W of the cover sheet satisfies: 2mm ≤ W ≤ 3mm.

[0008] In one embodiment, the thickness t of the cover sheet satisfies: t≤0.6mm.

[0009] This application also provides a venting and liquid-blocking valve, which includes an umbrella-shaped valve plate and a valve seat as described above. The valve seat has an air inlet side and an air outlet side arranged opposite to each other, an assembly hole provided on the air outlet side, and a venting hole connecting the air inlet side and the air outlet side.

[0010] The valve handle mates with the mounting hole, and the cover plate fits against the air outlet side and covers the air exchange hole.

[0011] In one embodiment, the ratio D1 / D2 of the distance D1 between the edge of the cover sheet in the length direction and the ventilation hole and the distance D2 between the edge of the cover sheet in the width direction and the ventilation hole satisfies: 1 / 2.75≤D1 / D2≤1 / 1.33.

[0012] In one embodiment, the distance D1 between the edge of the cover sheet in the length direction and the ventilation hole satisfies: 0.4mm≤D1≤0.6mm; and / or, the distance D2 between the edge of the cover sheet in the width direction and the ventilation hole satisfies: 0.8≤D2≤1.1mm.

[0013] In one embodiment, the valve seat is provided with a groove located on the air outlet side, the mounting hole and the air exchange hole are both located at the bottom of the groove, and the cover plate mates with the groove.

[0014] In one embodiment, the air-cooled liquid-blocking valve further includes a flow guide, one end of which is connected to the valve seat, and the other end of which extends away from the valve seat;

[0015] Furthermore, the guide element and the ventilation hole are connected and form an airflow passage when the ventilation hole is opened by the air pressure difference of the cover plate.

[0016] In one embodiment, the flow guide includes a connecting sleeve and a pipe body, one end of the connecting sleeve being sleeved with the valve seat, and the other end of the connecting sleeve being sleeved with the pipe body.

[0017] This application also provides an electronic atomizing device, which includes the umbrella-shaped valve plate as described above or the gas exchange liquid-blocking valve as described above.

[0018] Compared with the prior art, the embodiments of this application have the following advantages: In this application, by setting the cover sheet to be elongated and the ratio of the length L of the cover sheet to the width W of the cover sheet to satisfy: 1.5≤L / W≤3.5, the size of the cover sheet can be reduced, thereby reducing the contact area between the cover sheet and the liquid, and thus reducing the adhesive force generated after the cover sheet comes into contact with the liquid. This increases the amplitude of the cover sheet flipping up under the action of air pressure difference, thereby enhancing the ventilation effect. Attached Figure Description

Detailed Implementation

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This application provides an umbrella-shaped valve plate, which, by setting the cover plate of the umbrella-shaped valve plate to a non-traditional elongated shape instead of a traditional circle, and by setting the ratio of the length L of the cover plate to the width W of the cover plate, L / W, to satisfy: 1.5≤L / W≤3.5, can greatly reduce the size of the cover plate, thereby reducing the contact area between the cover plate and the liquid. This reduces the adhesive force generated when the cover plate comes into contact with the liquid, thereby increasing the amplitude of the cover plate flipping up under the action of air pressure difference, thus enhancing the ventilation effect.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0035] Please see Figure 1 This application provides an umbrella-shaped valve plate 10, which includes a valve handle 11 and a cover plate 12 connected to each other.

[0036] The valve handle 11 is perpendicular to the cover plate 12, and the valve handle 11 is connected to the center of the cover plate 12. The umbrella-shaped valve plate 10 is made of highly elastic materials such as rubber and silicone. This design allows the cover plate 12 to quickly return to its original shape when the pressure difference disappears, so as to ensure that the umbrella-shaped valve plate 10 automatically closes when the pressure difference disappears.

[0037] The working principle of the umbrella-shaped valve plate 10 is as follows: In the opening stage, when a pressure difference is generated inside and outside the liquid storage chamber 200a (which will be introduced below), the cover plate 12 flips up under the action of the pressure difference, opening the ventilation position, so that the liquid storage chamber 200a and the external environment can be ventilated through the ventilation position; In the closing stage, when the pressure difference inside and outside the liquid storage chamber 200a returns to equilibrium, the cover plate 12 returns to the ventilation position under the action of its own rebound force, so that the liquid storage chamber 200a and the external environment can stop being ventilated through the ventilation position.

[0038] Specifically, the valve handle 11 and the cover plate 12 are integrally formed by module injection molding, 3D printing or other methods, which can ensure the connection strength between the valve handle 11 and the cover plate 12. In addition, the valve handle 11 and the cover plate 12 can also be fixed by bonding, welding or other fixed connection methods, or the valve handle 11 and the cover plate 12 can also be fixed by detachable connection methods such as plug-in, snap-fit, threaded connection or other detachable connection methods.

[0039] Obviously, the valve handle 11 and the cover plate 12 can be configured in a one-to-one manner, or in a many-to-one manner; no specific limitation is made here.

[0040] Please see Figure 1 and Figure 2 The cover plate 12 is elongated, and the ratio L / W of the length L of the cover plate 12 to the width W of the cover plate 12 satisfies: 1.5 ≤ L / W ≤ 3.5. Optionally, the ratio L / W of the length L of the cover plate 12 to the width W of the cover plate 12 is selected from any one or a range formed by any two of the following: 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, and 3.5.

[0041] Specifically, the ratio of the length L of the cover sheet 12 to the width W of the cover sheet 12 is L / W = 2.0. This setting maximizes the range of the cover sheet 12 when it is flipped up under the action of air pressure difference, which is more conducive to ventilation.

[0042] Further, please refer to Figures 3 to 5 The side of the cover plate 12 facing the valve handle 11 and the side of the cover plate 12 facing away from the valve handle 11 both protrude in an arc shape in the direction from the valve handle 11 to the cover plate 12. This arrangement allows the cover plate 12 to cover the ventilation position in an inverted manner, thereby enhancing the airtightness of the cover plate 12.

[0043] And please see Figure 1The valve handle 11 has a limiting portion 111 extending circumferentially therein, located between the two ends of the valve handle 11 in the axial direction. This arrangement facilitates the fixing of the valve handle 11. Furthermore, the outer diameter of the limiting portion 111 first increases and then decreases in the direction from the cover plate 12 to the valve handle 11. This arrangement allows the outer peripheral wall of the limiting portion 111 to act as a guide during the assembly and disassembly of the valve handle 11, making the assembly and disassembly of the valve handle 11 convenient.

[0044] Preferably, please refer to Figures 3 to 5 The outer diameter of the portion of the valve handle 11 located between the cover plate 12 and the limiting portion 111 is larger than the outer diameter of the valve handle 11 located on the side of the limiting portion 111 away from the cover plate 12. This arrangement enhances the connection strength between the cover plate 12 and the valve handle 11. Alternatively, the outer diameter of the portion of the valve handle 11 located between the cover plate 12 and the limiting portion 111 can also be equal to or smaller than the outer diameter of the valve handle 11 located on the side of the limiting portion 111 away from the cover plate 12.

[0045] Obviously, the length of the portion of the valve handle 11 located between the cover plate 12 and the limiting portion 111 can be greater than, equal to or less than the length of the valve handle 11 located on the side of the limiting portion 111 away from the cover plate 12, and no specific limitation is made here.

[0046] Through the above technical solution, compared with the prior art, the cover plate 12 is elongated, and the ratio of its length L to its width W, L / W, satisfies the condition of 1.5 ≤ L / W ≤ 3.5. This design optimizes the shape and size of the cover plate 12, ensuring its airtightness while significantly reducing its size. This decreases the contact area between the cover plate 12 and the liquid, thereby reducing the adhesive force generated when the cover plate comes into contact with the liquid. This increases the extent to which the cover plate 12 can flip under pressure difference, enhancing the ventilation effect. Furthermore, due to the above design, the pressure required for the valve plate to flip is controllable, facilitating the flipping of the valve plate through pressure difference.

[0047] Please see Figure 1 and Figure 2 In one embodiment of this application, the length L of the cover sheet 12 satisfies: 4.5mm≤L≤7mm; the width W of the cover sheet 12 satisfies: 2mm≤W≤3mm. This setting can reduce the size of the cover sheet 12.

[0048] Optionally, the length L of the cover plate 12 is selected from any one or a range formed by any two of the following: 4.5mm, 4.6mm, 4.7mm, 4.8mm, 4.9mm, 5.0mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, 6.0mm, 6.1mm, 6.2mm, 6.3mm, 6.4mm, 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, and 7mm.

[0049] Optionally, the width W of the cover 12 is selected from any one or a combination of 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, and 3mm.

[0050] Preferably, the length L of the cover sheet 12 is 5mm and the width W of the cover sheet 12 is 2.5mm. This setting can reduce the size of the cover sheet 12, maximize the range of the cover sheet 12 flipping up under the action of air pressure difference, and ensure the airtightness of the cover sheet 12 when covering the ventilation position.

[0051] To further increase the extent to which the cover plate 12 flips up under the influence of air pressure difference, please refer to... Figure 1 In one embodiment of this application, the thickness t of the cover sheet 12 satisfies: t≤0.6mm.

[0052] Optionally, the thickness t of the cover sheet 12 is selected from any one or a range formed by any two of 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, 0.55 mm, and 0.6 mm.

[0053] Preferably, the thickness of the cover sheet 12 is t = 0.3 mm. This setting can reduce the weight of the cover sheet 12, thereby increasing the range of the cover sheet 12 flipping up under the action of air pressure difference, and can also ensure the airtightness of the cover sheet 12 when covering the ventilation position.

[0054] Please see Figures 5 to 8This application embodiment also provides a venting and liquid-blocking valve 100, which includes an umbrella-shaped valve plate 10 as described above and a valve seat 20. The valve seat 20 has an air inlet side 20a and an air outlet side 20b arranged opposite to each other, an assembly hole 20c provided on the air outlet side 20b, and a venting hole 20d connecting the air inlet side 20a and the air outlet side 20b. The valve handle 11 cooperates with the assembly hole 20c, and the cover plate 12 is attached to the air outlet side 20b and covers the venting hole 20d. With this arrangement, the cover plate 12 can be flipped up and open the venting hole 20d under the action of air pressure difference, so as to realize ventilation. In addition, the smaller umbrella-shaped valve plate 10 can be disassembled and installed from the electronic atomizing device 1000 together with the valve seat 20, thereby facilitating the disassembly and installation of the umbrella-shaped valve plate 10 from the electronic atomizing device 1000.

[0055] The specific structure of the umbrella-shaped valve plate 10 is as described in the above embodiments. Since the air-cooled liquid-blocking valve 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0056] In other embodiments, the valve seat 20 may not be provided, and the umbrella-shaped valve plate 10 may be directly assembled onto the electronic atomizing device 1000. Accordingly, the electronic atomizing device 1000 has an assembly position and an air exchange position arranged in parallel, the valve handle 11 cooperates with the assembly position, and the cover plate 12 covers the air exchange position.

[0057] Further, please refer to Figures 5 to 8 The air inlet side 20a is provided with a receiving groove 20e. The air exchange hole 20d and the assembly hole 20c are both connected to the bottom of the receiving groove 20e. The limiting part 111 abuts against the bottom of the receiving groove 20e. With this arrangement, the valve handle 11 and the limiting part 111 can be hidden in the valve seat 20, thereby reducing the size of the air exchange liquid-blocking valve 100.

[0058] And please see Figures 5 to 8 Two sealing rings 201 are integrally formed on the outer circumference of the valve seat 20. The two sealing rings 201 surround the mounting hole 20c and the vent hole 20d, and are spaced apart axially along the mounting hole 20c. This arrangement enhances the sealing performance between the outer circumferential wall of the valve seat 20 and the corresponding position of the electronic atomizing device 1000 when the valve seat 20 is installed. Clearly, the sealing rings are made of an elastic material so that the sealing rings 201 can generate an elastic sealing force when compressed.

[0059] To enhance the fixing strength of the cover plate 12, please refer to Figures 5 to 8In one embodiment of this application, the valve seat 20 is provided with a groove 20f, which is located on the air outlet side 20b. The assembly hole 20c and the ventilation hole 20d are both located at the bottom of the groove 20f. The cover plate 12 mates with the groove 20f, thus limiting the cover plate 12 through the groove 20f, thereby enhancing the fixing strength of the cover plate 12. The shape of the groove 20f is adapted to the shape of the cover plate 12, and the depth of the groove 20f is equal to the thickness of the cover plate 12, thus enhancing the mating strength between the cover plate 12 and the groove 20f.

[0060] Obviously, in this embodiment, the surface area of ​​the air outlet side 20b is larger than the cross-sectional area of ​​the cover sheet 12, which facilitates the creation of the groove 20f on the air outlet side 20b. In other embodiments, the groove 20f may not be provided, and the air outlet side 20b may completely overlap with the cover sheet 12, that is, the surface area of ​​the air outlet side 20b is equal to the cross-sectional area of ​​the cover sheet 12.

[0061] Please see Figure 2 In one embodiment of this application, the ratio D1 / D2 of the distance D1 between the edge of the cover sheet 12 in the length direction and the ventilation hole 20d and the distance D2 between the edge of the cover sheet 12 in the width direction and the ventilation hole 20d satisfies: 1 / 2.75≤D1 / D2≤1 / 1.33. This setting facilitates the lifting of the edge of the cover sheet 12 in the length direction to open the ventilation hole 20d when the cover sheet 12 is subjected to air pressure difference; on the other hand, it can ensure the airtightness of the cover sheet 12 when covering the ventilation hole 20d.

[0062] There are two ventilation holes 20d, and the two ventilation holes 20d are symmetrical about the valve handle 11 so that the two sides of the cover plate 12 in the length direction cover the two ventilation holes 20d respectively, and the ventilation holes 20d are directly opposite the middle position in the width direction of the cover plate 12. This makes the distance between the edge of the cover plate 12 in the length direction and each ventilation hole 20d equal, and the distance between the edge of the cover plate 12 in the width direction and each ventilation hole 20d equal.

[0063] Specifically, the distance D1 between the edge of the cover sheet 12 in the length direction and the ventilation hole 20d satisfies: 0.4mm≤D1≤0.6mm; the distance D2 between the edge of the cover sheet 12 in the width direction and the ventilation hole 20d satisfies: 0.8≤D2≤1.1mm.

[0064] Optionally, the distance D1 between the edge of the cover plate 12 along its length and the ventilation hole 20d is selected from any one or a combination of 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, 0.45mm, 0.46mm, 0.47mm, 0.48mm, 0.49mm, 0.5mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, and 0.6mm.

[0065] Optionally, the spacing D2 between the edge of the cover plate 12 in the width direction and the ventilation hole 20d is selected from any one or a combination of 0.8mm, 0.81mm, 0.82mm, 0.83mm, 0.84mm, 0.85mm, 0.86mm, 0.87mm, 0.88mm, 0.89mm, 0.9mm, 0.91mm, 0.92mm, 0.93mm, 0.94mm, 0.95mm, 0.96mm, 0.97mm, 0.98mm, 0.99mm, 1mm, and 1.1mm.

[0066] Preferably, D1 = 0.50 mm and D2 = 0.84 mm. This setting allows for a smaller pressure required when the edge of the cover sheet 12 is flipped up along its length, and also allows the cover sheet 12 to quickly return to cover the ventilation hole 20d after the pressure difference disappears.

[0067] Considering that if the venting valve 100 is installed at the bottom of the liquid storage chamber 200a (described below) and the outlet side 20b is located within the liquid storage chamber 200a, the liquid within the liquid storage chamber 200a will create pressure acting on the cover plate 12. This would result in a larger pressure difference required for the cover plate 12 to open the vent 20d, making it difficult for the cover plate 12 to open the vent 20d. Therefore, to avoid the liquid within the liquid storage chamber 200a creating pressure acting on the cover plate 12 when the venting valve 100 is installed at the bottom of the liquid storage chamber 200a and the outlet side 20b is located within the liquid storage chamber 200a, please refer to... Figures 5 to 8 In one embodiment of this application, the air exchange valve 100 further includes a guide member 30, one end of which is connected to the valve seat 20, and the other end of which extends away from the valve seat 20; and the guide member 30 and the air exchange hole 20d are connected and form an airflow passage when the cover plate 12 opens the air exchange hole 20d under the action of air pressure difference.

[0068] The connection between the flow guide 30 and the valve seat 20 can be a fixed connection or a detachable connection as described in the above embodiments, which will not be elaborated here.

[0069] It is worth mentioning that the flow guide 30 can be arranged vertically in the up-down direction or inclined in the up-down direction; furthermore, the flow guide 30 can be arranged in a straight line or in a curved shape, or part of the flow guide 30 can be arranged in a straight line and the other part in a curved shape, without any specific limitation here. Figure 7 The diagram shows the case where the flow guide 30 is arranged radially in the vertical direction and is in a straight line.

[0070] It is worth mentioning that, in practical applications, the end of the guide member 30 away from the valve seat 20 is kept above the water level in the storage chamber 200a. For example, the end of the guide member 30 away from the valve seat 20 is close to the top wall of the storage chamber 200a, and the distance between the water level in the storage chamber 200a and the top wall of the storage chamber 200a is relatively large. This ensures that the water in the storage chamber 200a will not enter the guide member 30.

[0071] Through the above technical solution, with the setting of the guide 30, the airflow can be guided to the space above the liquid storage chamber 200a when the air exchange hole 20d of the cover plate 12 is open, so as to realize air intake. At the same time, the liquid in the liquid storage chamber 200a and the cover plate 12 can be separated. In this way, the pressure formed by the liquid in the liquid storage chamber 200a acting on the cover plate 12 can be avoided when the air exchange valve 100 is assembled at the bottom of the liquid storage chamber 200a and the air outlet side 20b is located in the liquid storage chamber 200a.

[0072] Further, please refer to Figures 5 to 8 The venting and liquid-blocking valve 100 also includes a sealing ring 40, which is sandwiched between the guide member 30 and the valve seat 20. This arrangement can enhance the sealing between the inner peripheral wall of the guide member 30 and the outer peripheral wall of the valve seat 20, so as to prevent the liquid in the liquid storage chamber 200a from leaking into the interior of the guide member 30 through the gap between the inner peripheral wall of the guide member 30 and the outer peripheral wall of the valve seat 20.

[0073] There are many types of the aforementioned flow guide 30; please refer to [link / reference]. Figures 5 to 8 In one embodiment of this application, the flow guide 30 includes a connecting sleeve 31 and a tube body 32. One end of the connecting sleeve 31 is sleeved with the valve seat 20, and the other end of the connecting sleeve 31 is sleeved with the tube body 32. With this arrangement, the flow guide 30 can be installed by sequentially sleeved with the connecting sleeve 31 and the tube body 32; the flow guide 30 can be disassembled by sequentially removing the tube body 32 and the connecting sleeve 31, making the installation and disassembly of the flow guide 30 convenient.

[0074] Further, please refer to Figures 5 to 8The connecting sleeve 31 includes a first section 311 and a second section 312 connected to each other. The diameter of the first section 311 is larger than the diameter of the second section 312. The first section 311 is sleeved with the valve seat 20, and the second section 312 is sleeved with the pipe body 32. This arrangement makes it convenient to assemble and disassemble the connecting sleeve 31 with the valve seat 20 and the connecting sleeve 31 with the pipe body 32.

[0075] The connection between the first segment 311 and the second segment 312 and the air outlet side 20b has a gap to provide the space required for the cover sheet 12 to flip up due to the air pressure difference.

[0076] Obviously, when the guide 30 includes the connecting sleeve 31 and the pipe body 32, the sealing ring 40 is sandwiched between the first section 311 of the connecting sleeve 31 and the valve seat 20.

[0077] Furthermore, please refer to Figures 5 to 8 The outer diameter of the second segment 312 is gradually reduced in the direction from the first segment 311 to the second segment 312. The inner peripheral wall of the tube body 32 is fitted with the outer peripheral wall of the second segment 312. This arrangement allows the outer peripheral wall of the second segment 312 to act as a guide, so that the tube body 32 can be fitted onto the second segment 312.

[0078] In other embodiments, the guide 30 may also be configured as a pipe extending vertically.

[0079] Please see Figure 9 and Figure 10 This application also provides an electronic atomizing device 1000, which includes the gas exchange liquid-blocking valve 100 and the device body 200 as described above. The gas exchange liquid-blocking valve 100 is disposed on the device body 200. The specific structure of the gas exchange liquid-blocking valve 100 is the same as described in the above embodiments. Since the electronic atomizing device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0080] There are many types of electronic atomizing devices 1000. Electronic atomizing devices 1000 can be atomizing fans, humidifiers, aerosol generators, and other devices with atomizing functions.

[0081] Please refer to Figure 10 The device body 200 has a liquid storage chamber 200a. The air exchange liquid diaphragm valve 100 can be installed on the inner side of the top, the outer side of the top, the inner side of the side, the outer side of the side, the inner side of the bottom, and the outer side of the bottom of the liquid storage chamber 200a. Similarly, the liquid storage chamber 200a can also be located on the top, bottom, or side of the device body 200. No specific limitation is made here.

[0082] Obviously, when the venting and liquid-blocking valve 100 is installed on the equipment body 200, the venting and liquid-blocking valve 100 can be used as an air inlet. Correspondingly, the outlet side 20b of the valve seat 20 is inside, and the inlet side 20a is outside. The guide element 30 is connected to the outlet side 20b, so that when the cover plate 12 opens the venting hole 20d under the action of air pressure difference, the air in the external environment flows into the liquid storage chamber 200a after passing through the venting hole 20d and the guide element 30 in sequence. Figure 5 This situation is illustrated in the figure; the venting and liquid-blocking valve 100 can also be used to vent. Accordingly, the inlet side 20a of the valve seat 20 is inside and the outlet side 20b is outside. The guide 30 is connected to the inlet side 20a, so that when the cover plate 12 opens the venting hole 20d under the action of the air pressure difference, the air in the liquid storage chamber 200a flows into the external environment through the venting hole 20d and the guide 30 in sequence.

[0083] Understandably, please refer to Figure 9 and Figure 10 The portion of the device body 200 containing the liquid storage chamber 200a is formed as a liquid storage tank 211. The liquid storage tank 211 can be integrally formed with the shell of the device body 200, or it can be an independently set box. It is fixed to the shell of the device body 200 by a fixed connection or a detachable connection in the above embodiments. No specific limitation is made here.

[0084] In some embodiments, please refer to Figures 3 to 5 , Figure 9 as well as Figure 10 When the electronic atomizing device 1000 is an atomizing fan, the device body 200 includes a handheld part 210 and a fan head 220 connected to each other. The bottom of the handheld part 210 is formed as a liquid storage tank 211, and the space inside the liquid storage tank 211 is formed as a liquid storage chamber 200a. The bottom wall of the liquid storage chamber 200a is provided with a mounting groove 200b, and the bottom wall of the mounting groove 200b is provided with a ventilation port 200c that communicates with the external environment. A part of the mounting groove 200b cooperates with the valve seat 20, and the other part of the mounting groove 200b cooperates with the first section 311 of the connecting sleeve 31. This can enhance the stability of the ventilation and liquid-blocking valve 100.

[0085] Further, please refer to Figures 3 to 5 , Figure 9 as well as Figure 10 The liquid storage tank 211 includes a detachably connected housing 2111 and a cover 2112. The housing 2111 and the cover 2112 enclose a liquid storage cavity 200a. The inner side of the cover 2112 forms the bottom wall of the liquid storage cavity 200a. This arrangement allows the venting and liquid-blocking valve 100 to be installed on the cover 2112, enabling the venting and liquid-blocking valve 100 to be disassembled and installed together with the cover 2112, making the disassembly and assembly of the liquid storage tank 211 convenient.

[0086] In other embodiments, the cavity wall of the liquid storage chamber 200a may be partially through to form an installation hole, and the first section 311 of the valve seat 20 and the connecting sleeve 31 may be embedded in the installation hole.
