Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to a protective outer casing, an outer casing, and an electronic cigarette. Background Technology

[0002] As the e-cigarette market continues to expand, consumers are increasingly demanding higher quality e-cigarettes, with the appearance and comfort of use becoming key factors influencing their purchasing decisions.

[0003] Some e-cigarettes use hard, cold plastic or metal materials, which lack a soft, warm feel when in contact with the skin, and it's difficult to find a comfortable grip point, leading to discomfort after prolonged use. Based on this, many e-cigarette products on the market currently add an elastic layer to the casing to provide a more comfortable grip. Then, for dust protection, decoration, and other functions, non-woven fabric is usually placed over the elastic layer. However, due to the structural characteristics of non-woven fabric, the relatively tight network formed by its interwoven fibers limits the elastic layer's resilience. When a user holds the e-cigarette, the elastic layer cannot fully utilize its elasticity, failing to provide timely and effective deformation feedback based on hand pressure and grip movements. This significantly diminishes the intended soft, conforming, and elastic feel, ultimately affecting the overall user experience. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a protective shell that reduces the limitation of traditional one-piece nonwoven fabric on the deformation of the elastomer by using a split design. This ensures that the outermost contact layer is made of nonwoven fabric to meet functions such as dust protection and decoration. At the same time, it increases the deformation of the elastomer to increase the user's expectation of a soft, close-fitting, and elastic feel, thereby improving the user experience.

[0005] Another objective of this invention is to provide a casing that improves the user experience by covering the outside of the casing with a protective cover that has a bulging effect.

[0006] Another objective of this utility model is to provide an electronic cigarette that, by setting a protective shell, is not only waterproof and wear-resistant, but also has a good texture and a strong three-dimensional effect.

[0007] A protective casing, covering the exterior of an electronic cigarette casing, includes:

[0008] Base;

[0009] A first nonwoven fabric is provided to cover the substrate; a through hole is provided in the middle of the first nonwoven fabric.

[0010] An elastomer is disposed at the through hole and at least partially protrudes from the through hole;

[0011] A second nonwoven fabric is applied over the elastomer.

[0012] Furthermore, the size of the elastomer at least completely covers the through hole.

[0013] Specifically, the elastomer is completely embedded within the through hole;

[0014] The second nonwoven fabric has a larger external dimension than the elastomer, so that the second nonwoven fabric completely covers the elastomer.

[0015] Specifically, the size of the elastomer is larger than the size of the through hole, and the elastomer is sandwiched between the substrate and the first nonwoven fabric, or the elastomer is sandwiched between the first nonwoven fabric and the second nonwoven fabric.

[0016] Furthermore, the first nonwoven fabric and the second nonwoven fabric are bonded to the elastomer by heat pressing, gluing or sewing.

[0017] Specifically, the substrate is leather; the elastomer is sponge.

[0018] Furthermore, both the first nonwoven fabric and the second nonwoven fabric include a base fabric layer, an elastic layer, a breathable layer, and a wear-resistant layer arranged sequentially from the inside out.

[0019] Furthermore, the first nonwoven fabric and the second nonwoven fabric also include an anti-slip layer disposed on the inner side of the base fabric layer.

[0020] A housing, comprising:

[0021] The housing, and the outer protective sleeve described in this utility model.

[0022] An electronic cigarette includes: the outer shell described in this utility model.

[0023] The beneficial effects of this utility model are as follows:

[0024] (1) Use separate non-woven fabric to replace the traditional one-piece non-woven fabric to reduce the restriction on the shape of the elastic body, thereby achieving a significant bulging effect and increasing the soft touch and three-dimensionality of the electronic cigarette shell.

[0025] (2) By using the first non-woven fabric and the second non-woven fabric together, the requirement of non-woven fabric as the outermost contact layer to fully cover the outer shell protective cover is met.

[0026] (3) Using leather-like materials as the base, it has good wear resistance and tear resistance, and at the same time helps to keep the surface of the e-cigarette dry, preventing damage to the e-cigarette due to problems such as water vapor condensation, and extending the service life of the e-cigarette.

[0027] (4) By setting an anti-slip layer in the nonwoven fabric that is in direct contact with the elastomer, misalignment between the second nonwoven fabric and the elastomer can be avoided during use.

[0028] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] Traditional protective cases typically sandwich an elastomer between a base and a nonwoven fabric. However, due to the structural characteristics of the nonwoven fabric itself, the relatively tight network formed by the interwoven fibers limits the elastic layer's resilience to some extent. When a user holds an e-cigarette, the elastic layer cannot fully utilize its elastic properties and cannot deform in a timely and effective manner according to hand pressure and gripping movements, resulting in a poor three-dimensional bulge feel.

[0041] Please see Figure 1-3 This application provides a protective outer casing for covering the exterior of an electronic cigarette casing, comprising: a base 10, a first nonwoven fabric 20, an elastomer 30, and a second nonwoven fabric 40; the first nonwoven fabric 20 covers the base 10; a through hole 21 is formed in the middle of the first nonwoven fabric 20, and the elastomer 30 is disposed at the through hole 21 and at least partially protrudes from the through hole 21. The second nonwoven fabric 40 covers the elastomer 30.

[0042] The protective shell provided in this application reduces the limitation of traditional one-piece nonwoven fabric on the deformation of the elastomer by using a split design. This ensures that the outermost contact layer is nonwoven fabric, thereby fulfilling functions such as dust protection and decoration. At the same time, it increases the deformation of the elastomer, thereby increasing the user's expectation of a soft, close-fitting, and elastic feel and improving the user experience.

[0043] Furthermore, in some embodiments, the size of the elastomer 30 at least completely covers the through-hole 21. In this configuration, the lower end face of the elastomer 30 is attached to the substrate 10, and its thickness is greater than that of the first nonwoven fabric 20, so that it protrudes from the through-hole 21.

[0044] Please see Figure 1 and Figure 4 As an example, in some embodiments, the elastomer 30 is completely embedded within the through-hole 21, meaning the external dimensions of the elastomer 30 are adapted to the dimensions of the through-hole 21 so that the elastomer 30 just completely covers the through-hole 21. In this configuration, the external dimensions of the second nonwoven fabric 40 are larger than those of the elastomer 30, so that the second nonwoven fabric 40 completely covers the elastomer 30. It is understood that the edge of the second nonwoven fabric 40 may only be fixed to the outer periphery of the through-hole 21, in which case the elastomer 30 is constrained within the through-hole 21, naturally sandwiched between the second nonwoven fabric 40 and the substrate 10. In other embodiments, the edge of the second nonwoven fabric 40 may be fixed to both the edge of the elastomer 30 and the outer periphery of the through-hole 21, achieving relative fixation of the three.

[0045] Please see Figure 5-7 As an example, in some other embodiments, the size of the elastomer 30 is larger than the size of the through-hole 21; the edge of the elastomer 30 is sandwiched between the base 10 and the first nonwoven fabric 20, or the edge of the elastomer 30 is sandwiched between the first nonwoven fabric 20 and the second nonwoven fabric 40. In this arrangement, the first nonwoven fabric 20 and the second nonwoven fabric 40 are bonded to the edge of the elastomer 30 by heat pressing, gluing, or sewing, achieving relative fixation of the three. Preferably, the edge of the elastomer 30 is sandwiched between the base 10 and the first nonwoven fabric 20; the size of the second nonwoven fabric 40 completely covers the through-hole 21, and its edge is attached to the outer periphery of the through-hole 21, directly adhering to the first nonwoven fabric 20, thus enhancing the overall integrity of the outer shell protective cover.

[0046] Furthermore, in some embodiments, the base is leather, which has good abrasion resistance and tear resistance, and can protect the e-cigarette shell from damage caused by friction and minor impacts during daily use to a certain extent. At the same time, leather has a certain degree of hygroscopicity, which can absorb a small amount of moisture in the air, helping to keep the surface of the e-cigarette dry and preventing damage to the e-cigarette due to moisture condensation and other problems, thus extending the service life of the e-cigarette. Specifically, the leather can be natural leather or artificial leather.

[0047] Furthermore, in some embodiments, the elastomer can be a sponge, foam material, or soft plastic. The softness of the elastomer increases grip comfort and improves the feel. Simultaneously, the elasticity and softness of the elastomer provide good cushioning when the e-cigarette is subjected to impact or vibration, protecting the e-cigarette's shell and internal components. In addition, it provides some heat insulation, preventing burns to the user and stabilizing the internal temperature. In this embodiment, the elastomer is a sponge. Because sponge is soft and has high elastic recovery, when wrapped around the e-cigarette shell, it maintains its fluffy state and bulges under no external force or slight compression, easily creating a noticeable bulge effect, increasing the soft touch and three-dimensional feel of the e-cigarette shell.

[0048] Furthermore, in some embodiments, the first nonwoven fabric 20 and the second nonwoven fabric 40 may be made of the same material or different materials, without limitation.

[0049] As an example, the first nonwoven fabric 20 and the second nonwoven fabric 40 are made of the same material, both comprising a base fabric layer, an elastic layer, a breathable layer, and an abrasion-resistant layer arranged sequentially from the inside out. Specifically, the elastic layer is used to improve the overall elasticity and tensile strength of the nonwoven fabric, while the breathable layer improves the air permeability of the nonwoven fabric. The abrasion-resistant layer prevents the nonwoven fabric from being torn by tensile forces, greatly improving the tensile and abrasion resistance of the nonwoven fabric. In some embodiments, to further improve the abrasion resistance and grip of the nonwoven fabric, the abrasion-resistant layer also includes arrayed or staggered abrasion-resistant ridges on its exterior to improve the overall abrasion resistance of the nonwoven fabric, while also enhancing its tensile strength.

[0050] Furthermore, in some embodiments, the first nonwoven fabric 20 and the second nonwoven fabric 40 are also provided with an anti-slip layer. The anti-slip layer is located inside the base fabric layer and is in direct contact with the elastomer 30 to ensure that the second nonwoven fabric 40 and the elastomer 30 deform synchronously. This is to prevent the second nonwoven fabric 40 and the elastomer 30 from shifting during use, which would affect the user's experience. At the same time, it also prevents the second nonwoven fabric 40 from falling off due to frequent shifting.

[0051] It is understandable that the first nonwoven fabric 20 and the second nonwoven fabric 40 can be designed with the same or different patterns according to appearance requirements, which will not be described in detail here.

[0052] This application embodiment also provides an outer shell, including: a shell and an outer shell protective cover as described in this application embodiment. The outer shell protective cover fits tightly to the outside of the shell or is detachably fitted onto the outside of the shell, allowing the user to feel a soft touch while holding and using it, and providing a better three-dimensional appearance.

[0053] This application also provides an electronic cigarette, including: an atomizing mechanism and a shell as described in this application embodiment. The atomizing mechanism is disposed inside the shell. In addition to providing a soft touch and three-dimensional feel, the shell can also isolate external water stains, oil stains and other foreign objects from entering the shell, so as to avoid corrosion of the electronic components of the atomizing mechanism and affect the stability and service life of the electronic cigarette.

[0054] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0055] (1) Use separate non-woven fabric to replace the traditional one-piece non-woven fabric to reduce the restriction on the shape of the elastic body, thereby achieving a significant bulging effect and increasing the soft touch and three-dimensionality of the electronic cigarette shell.

[0056] (2) By using the first non-woven fabric and the second non-woven fabric together, the requirement of non-woven fabric as the outermost contact layer to fully cover the outer shell protective cover is met.

[0057] (3) Using leather-like materials as the base, it has good wear resistance and tear resistance, and at the same time helps to keep the surface of the e-cigarette dry, preventing damage to the e-cigarette due to problems such as water vapor condensation, and extending the service life of the e-cigarette.

[0058] (4) By setting an anti-slip layer in the nonwoven fabric that is in direct contact with the elastomer, misalignment between the second nonwoven fabric and the elastomer can be avoided during use.

[0059] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
