Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, specifically to a housing and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are a common type of electronic product. Their atomizers can heat and atomize liquid aerosol matrix to form aerosols.

[0003] In related technologies, the liquid aerosol-forming matrix is ​​generally stored in a reservoir. When the amount of aerosol-forming matrix in an electronic atomizing device decreases, and the air space within the reservoir increases, a sudden change in the operating environment—such as changes in external air pressure during air travel (e.g., flying or mountain climbing) or moving from a low-temperature environment to a high-temperature environment (e.g., changes in air pressure within the reservoir) can disrupt the original internal and external pressure balance between the electronic atomizing device and its operating environment. In this case, the air pressure within the reservoir becomes relatively high, and the pressure difference causes the aerosol-forming matrix to be squeezed out from the atomizing components, resulting in leakage. This phenomenon is particularly pronounced in large-capacity electronic atomizing devices when the remaining aerosol-forming matrix is ​​low. Utility Model Content

[0004] In view of this, this application provides a housing and an electronic atomizing device to solve the problem of leakage caused by internal and external pressure differences in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A housing for use in an electronic atomizing device includes a wall structure that encloses a reservoir for storing an aerosol-forming matrix.

[0007] The wall structure includes a main body and a deformable body. The deformable body is sealed to the main body, and the deformable body can deform due to the pressure difference on both sides of the deformable body. When the pressure of the liquid storage chamber is higher than the ambient pressure, the deformable body protrudes relative to the main body to expand the liquid storage chamber.

[0008] Optionally, when the pressure in the liquid storage chamber is lower than the ambient pressure, the deformable body deforms inward relative to the main body to shrink the liquid storage chamber.

[0009] Optionally, the housing has a receiving cavity in which the deformable part is exposed, and the receiving cavity provides space for the deformable part to protrude.

[0010] Optionally, the housing includes a spliced ​​atomizer housing and a battery housing, the liquid storage chamber is formed in the atomizer housing, and the battery housing and the atomizer housing enclose the receiving cavity.

[0011] Optionally, the deformation form is a silicone part or a rubber part.

[0012] Optionally, the sealing connection surface between the main body and the deformed shape is a stepped surface.

[0013] Optionally, the deformable portion includes a central portion and an edge portion surrounding and connected around the central portion, the edge portion having a greater thickness than the central portion.

[0014] Optionally, the thickness of the central portion is 0.3mm-0.4mm.

[0015] Optionally, the deformation form is an aluminum foil sheet or a plastic film.

[0016] An electronic atomizing device, comprising:

[0017] The shell is any one of the shells mentioned above;

[0018] An atomizing component is disposed in the housing and is used to heat and atomize the aerosol to form a matrix;

[0019] A power supply device is disposed in the housing and is used to provide electrical energy for the operation of the atomizing assembly;

[0020] The power supply device is located in the accommodating cavity of the housing, and the deformable part is separated between the accommodating cavity and the liquid storage cavity.

[0021] The housing provided in this application is used in an electronic atomizing device. The housing includes a wall structure that encloses a liquid storage cavity for storing an aerosol matrix. The wall structure includes a main body and a deformable body. The deformable body is sealed to the main body, and the deformable body can deform due to the pressure difference on both sides of the deformable body. When the pressure of the liquid storage cavity is higher than the ambient pressure, the deformable body protrudes relative to the main body to expand the liquid storage cavity. In this design, the applicant considered that the essence of leakage in electronic atomizing devices is caused by an imbalance of internal and external pressure. Therefore, the design was based on the wall structure that encloses the liquid storage chamber. The increase in air pressure inside the liquid storage chamber caused by sudden changes in the usage environment is transferred to the local deformation of the wall structure. In other words, the local part of the wall structure is designed as a deformable shape that can deform due to the pressure difference between the inside and outside. When the air pressure inside the liquid storage chamber increases, the deformable shape will bulge outward to balance the air pressure. That is, the wall structure of the shell provided in this application can adapt to air pressure changes through its own shape change. Therefore, the shell provided in this application can avoid leakage problems when applied to the production and manufacturing of electronic atomizing devices, and solves the problem of leakage caused by internal and external pressure differences in existing electronic atomizing devices.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] In related technologies, electronic atomizing devices generally consist of an atomizer module and a power supply module. The atomizer module has structures such as a liquid storage chamber 101, an atomizing component 300, and an air passage 400. Figure 1 An exemplary embodiment shows a liquid reservoir 101 formed around an air passage 400, an atomizing component 300 communicating with the liquid reservoir 101, and the atomizing surface of the atomizing component 300 exposed in the air passage 400. The atomizing component 300 generally includes a porous substrate and a heating element.

[0034] The applicant discovered that in some usage scenarios, the electronic atomizing device would leak, that is, the liquid aerosol forming matrix would overflow from the atomizing component 300 and flow into the airway 400.

[0035] One scenario involves transitions between high and low altitudes. Based on the principle that higher altitudes result in lower temperatures and atmospheric pressure, electronic atomizers typically ship with internal and external air pressures equal. This usually requires a silicone stopper for sealing before final packaging. In other words, when transported to high-altitude areas, the internal air pressure is slightly higher than the operating environment. Because the atomizing component 300's oil-locking ability outweighs the effect of atmospheric pressure differences, leakage doesn't occur initially. However, as the user inhales more frequently, the amount of aerosol forming the matrix decreases, and the gas space in the reservoir 101 increases. The internal and external pressure difference gradually surpasses the oil-locking ability of the atomizing component 300, leading to leakage.

[0036] Another scenario is the transition between high and low temperatures. In the cold season, users can use the electronic atomizing device outdoors without any problems. However, when the product is brought indoors, the temperature is higher indoors than outdoors. When the product is suddenly moved from a low-temperature environment to a high-temperature environment, the air in the product's liquid storage chamber 101 expands due to heat and the air pressure increases, causing the product to leak indoors.

[0037] The leakage is more pronounced when there is less aerosol forming matrix and more gas in the liquid storage chamber 101. So basically, the leakage occurs when the aerosol forming matrix is ​​almost used up.

[0038] like Figures 1-3 As shown in the figure, this application provides a housing for use in an electronic atomizing device. The housing includes a wall structure that encloses a liquid storage cavity 101 for storing an aerosol-forming matrix. The wall structure includes a main body 110 and a deformable part 120. The main body 110 is made of a rigid and non-deformable material. The deformable part 120 is sealed to the main body 110 and can deform due to the pressure difference between its two sides, that is, due to the pressure difference between the liquid storage cavity 101 and the operating environment. When the pressure in the liquid storage cavity 101 is higher than the pressure in the operating environment, the deformable part 120 protrudes relative to the main body 110, that is, the deformable part 120 protrudes outward from the liquid storage cavity 101 to expand the liquid storage cavity 101. The deformation of the deformable part 120 is preferably elastic deformation.

[0039] In this design, the applicant considered that the essence of leakage in electronic atomizing devices is caused by an imbalance of internal and external pressure differences. Therefore, the design was based on the wall structure that encloses the liquid storage chamber 101. The increase in air pressure inside the liquid storage chamber 101 caused by sudden changes in the usage environment is transferred to the local deformation of the wall structure. That is, the local design of the wall structure is a deformable shape 120 that can deform due to the pressure difference between the inside and outside. When the air pressure inside the liquid storage chamber 101 increases, the deformable shape 120 will bulge outward to balance the air pressure. In other words, the wall structure of the shell provided by this application can adapt to the air pressure change and offset the pressure difference through its own shape change. Therefore, the shell provided by this application can avoid the leakage problem when applied to the production and manufacturing of electronic atomizing devices, and solves the problem of leakage caused by internal and external pressure differences in existing electronic atomizing devices.

[0040] In other embodiments, when the pressure in the liquid storage chamber 101 is lower than the ambient pressure, the deformable body 120 deforms inward relative to the main body 110, that is, the deformable body 120 deforms inward toward the liquid storage chamber 101 to shrink the liquid storage chamber 101. In other words, the deformation of the deformable body 120 is bidirectional. With this configuration, when the pressure in the liquid storage chamber 101 is lower than the ambient pressure, the deformable body 120 adapts to the pressure change by changing its shape, offsetting the pressure difference, and ensuring that the aerosol forming matrix is ​​discharged normally at the atomizing component 300 without causing dry burning.

[0041] It should be noted that the sealing connection between the deformable part 120 and the main body 110 can be achieved by adhesive bonding. In other embodiments, the deformable part 120 and the main body 110 can also be a single integrally formed structure.

[0042] Regarding the placement of the deformer 120, theoretically, the deformer 120 can be exposed on the outer surface of the housing or hidden inside the housing.

[0043] In some alternative embodiments, the housing has a receiving cavity 201 in which the deformable part 120 is exposed, i.e., the deformable part 120 is separated between the receiving cavity 201 and the reservoir 101, and the receiving cavity 201 provides space for the deformable part 120 to protrude. Specifically, the receiving cavity 201 may be a space for mounting other structures in the electronic atomizing device, or it may be a space entirely dedicated to accommodating the expansion of the reservoir 101.

[0044] With this design, the deformable part 120 is not exposed on the outer surface of the housing but is hidden inside the housing. This not only makes the housing aesthetically pleasing and does not affect the appearance design of the electronic atomizing device, but also eliminates the risk of accidental pressing during transportation or user use.

[0045] In some alternative embodiments, the housing includes a spliced ​​atomizer housing 100 and a battery housing 200, which may be detachably connected. The atomizer housing 100 includes a wall structure, a liquid storage chamber 101 is formed in the atomizer housing 100, and the battery housing 200 and the atomizer housing 100 enclose a receiving cavity 201.

[0046] With this configuration, the accommodating cavity 201 can be used to accommodate the power supply device, making the accommodating cavity 201 multifunctional and with low design and development costs. Moreover, the deformable part 120 is designed on the same side as the battery housing 200, which is beneficial to the high degree of exposure of the part where the deformable part 120 is located before the atomizer housing 100 and the battery housing 200 are assembled, thereby facilitating the sealing connection process of the deformable part 120 on the main body 110.

[0047] Regarding the specific material of the wall structure, the main body 110 can use the conventional material of the shell of the electronic atomizing device, such as metal or hard plastic. The material of the deformable part 120 must be easily deformable, not easily broken, and must not chemically react with the sol matrix, and must be a food-grade material.

[0048] In some alternative embodiments, the deformable part 120 is a silicone or rubber part. In its natural state, it has a certain shape and stable form, and it can deform under pressure.

[0049] Furthermore, in some optional embodiments, the sealing connection surface between the main body 110 and the deformed form 120 is a stepped surface. In other words, the deformed form 120 has an outer edge, and the main body 110 has a recessed stepped surface. This configuration increases the contact area between the main body 110 and the deformed form 120, thus increasing the area of ​​the sealing connection surface, making the sealing connection between the main body 110 and the deformed form 120 more stable and reliable.

[0050] Preferably, the planar portion of the main body 110 has an opening, and the deformable part 120 is sealed and connected in the opening. This facilitates manufacturing.

[0051] Furthermore, in some optional embodiments, the deformable portion 120 includes a central portion 1201 and an edge portion 1202 surrounding and connected to the central portion 1201. The central portion 1201 and the edge portion 1202 are integrally formed, and the thickness of the edge portion 1202 is greater than the thickness of the central portion 1201. In conjunction with the foregoing embodiments, the edge portion 1202 is sealed to the body 110, and the sealing connection surface is a stepped surface.

[0052] With this configuration, the edge portion 1202 is thicker and makes a sealed contact with and connection to the main body 110, which helps to provide a certain shape retention capability and makes the sealed connection more stable; the central portion 1201, located in the middle, is a weak area, and its thickness is thinner as the main part, which helps to deform under the action of air pressure difference.

[0053] Furthermore, in some specific embodiments, the thickness of the central portion 1201 is 0.3mm-0.4mm, including the values ​​at both ends. The applicant found in experiments and verifications that, theoretically, the thinner the deformable part 120, the better, because a thinner part is more easily deformed by pressure differences, resulting in better pressure balance. However, in practice, manufacturing needs to be considered. For example, with silicone parts, the production of silicone products is affected by various factors, such as mold precision and vulcanization processes. When the thickness of the silicone part is below 0.3mm, the production difficulty increases significantly, the product quality stability may deteriorate, and the cost will increase accordingly. Silicone parts with a thickness of 0.3mm have very weak puncture resistance and tensile strength, and are easily torn when removed from the protective film. Excessive tensile force can also cause irreversible deformation of the product, making it unsuitable for installation. Therefore, the thinnest design thickness for silicone parts is 0.3mm, with 0.4mm recommended. However, exceeding 0.4mm results in too low deformation sensitivity, hence the aforementioned design range.

[0054] In some other alternative embodiments, the deformable part 120 may also be a flexible substrate, such as an aluminum foil or a plastic film.

[0055] For example, the deformable part 120 is a plastic film with a thickness of 0.03mm-0.1mm. The plastic film can be common materials such as polyethylene (PE) and polyvinylidene chloride (PVDC), which are easily deformable and not easily broken.

[0056] Based on the aforementioned housing, this application embodiment also provides an electronic atomizing device, which includes a housing, an atomizing component 300, and a power supply device. The housing is the aforementioned housing, the atomizing component 300 is disposed within the housing and used to heat and atomize the aerosol to form a matrix, and the power supply device is disposed within the housing and used to provide electrical energy for the operation of the atomizing component 300. The power supply device is located in the accommodating cavity 201 of the housing, and the deformable part 120 is separated between the accommodating cavity 201 and the liquid storage cavity 101. Since this electronic atomizing device has the aforementioned housing, the beneficial effects brought by the housing of the electronic atomizing device are described above and will not be repeated here.
