Description

Technical Field

[0001] The present application relates to the technical field of hair dryers, and in particular to an inner shell component of a hair dryer and a hair dryer. Background Art

[0002] Hair dryers are mainly used for drying and styling hair, but they are also often used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production and art. However, hair dryers have high requirements for the sealing of the shell, especially the air outlet section above the fan. If the sealing is not good, it will cause air leakage in the shell and noise in the air duct, thus affecting the efficiency of the hair dryer and the user experience.

[0003] The inner shell assembly of a hair dryer includes a cylinder shell and a handle shell. The hair dryers currently on the market mainly seal the inner shell assembly of the hair dryer by sealing the connection between the cylinder shell and the handle shell.

The sealing performance only depends on the fit of the splicing surface. Due to manufacturing process and material limitations, there may be a small gap on the splicing surface, resulting in unsatisfactory sealing.

[0058] The utility model provides an inner shell assembly 100 of a hair dryer.

[0059] In the embodiment of the present utility model, please refer to Figures 2 to 10 The inner shell assembly 100 of the hair dryer includes a handle shell 10 and a first sealing member 20. The handle shell 10 includes a first subshell 11 and a second subshell 12. The first subshell 11 and the second subshell 12 enclose a mounting cavity 10a, and a gas duct (not shown) is arranged in the mounting cavity 10a; the first subshell 11 has a first splicing surface 111 spliced ​​with the second subshell 12, and the first sealing member 20 is arranged on the first splicing surface 111; the second subshell 12 has a second splicing surface 121 arranged corresponding to the first splicing surface 111, and the second splicing surface 121 is convexly provided with a first convex strip 1211, and the first convex strip 1211 abuts against the first sealing member 20.

[0060] In this embodiment, the outer surface shapes of the first sub-shell 11 and the second sub-shell 12 can be the same or different. In order to better hold and improve the comfort of the user, the first sub-shell 11 and the second sub-shell 12 with the same outer surface shape are generally used to enclose a cylindrical shape, and an installation cavity 10a for installing the fan assembly 80 and other parts is formed inside. The first splicing surface 111 can be set on the complete connecting surface where the first sub-shell 11 and the second sub-shell 12 are in contact, or it can be set only on the partial connecting surface where the first sub-shell 11 and the second sub-shell 12 are in contact, which is not limited here.

[0061] The first sealing member 20 may be a sheet-like structure, and its material may be silicone, rubber or other materials with a buffering effect. The first sealing member 20 and the first joint surface 111 may be connected by embedding, bonding or other connection methods. The first convex strip 1211 is used to squeeze the first sealing member 20, so that the first sealing member 20 is deformed to obtain a better sealing effect. The first convex strip 1211 may extend longitudinally, transversely, or in other directions, and is not limited here.

[0062] The utility model improves the sealing performance of the first sub-shell 11 and the second sub-shell 12 by providing a first sealing member 20 between the first splicing surface 111 and the second splicing surface 121. On this basis, a first convex strip 1211 is provided on the second splicing surface 121, so that when the first splicing surface 111 and the second splicing surface 121 are spliced, the first convex strip 1211 applies a greater contact pressure to the first sealing member 20, and more effectively compresses the first sealing member 20, so that the first sealing member 20 is deformed, and fills the tiny gap in the splicing surface caused by manufacturing errors, significantly improving the sealing performance of the hair dryer 200, and reducing air leakage. For example, if the first convex strip 1211 is not provided, the first sealing member 20 is sandwiched between the first splicing surface 111 and the second splicing surface 121, which will cause a larger extrusion area between the sealing member and the splicing surface, and the sealing member cannot be effectively extruded to cause deformation, resulting in a smaller sealing area.

[0063] Secondly, the first convex strip 1211 is provided on the second splicing surface 121 to abut against the first sealing member 20, so that when the first splicing surface 111 and the second splicing surface 121 are spliced, there may be a process error in the thickness of the first sealing member 20. For example, when the first sealing member 20 is embedded in the first splicing surface 111 to achieve the connection between the two, if the thickness of the first sealing member 20 is thin due to a process error, the first convex strip 1211 can squeeze the first sealing member 20 and deform the first sealing member 20, thereby improving the sealing performance.

[0064] In one embodiment, the handle shell 10 also includes an air inlet section 13 and an air outlet section 14, and at least the air outlet section 14 is provided with a first ridge 1211 and a first seal 20; the handle shell 10 is in the shape of an elongated strip, the first sub-shell 11 and the second sub-shell 12 are spliced ​​along the thickness direction of the handle shell 10, and the first ridge 1211 extends along the length direction of the handle shell 10.

[0065] In this embodiment, the air inlet section 13 is provided with an air inlet for air intake, and the air outlet section 14 is used to transport the air in the air inlet section 13 to the outside. Since the air outlet section 14 is the main exchange channel between the inside and the outside of the hair dryer 200, the sealing member and the convex strip are provided here to help improve the sealing performance of the handle housing 10 and prevent air leakage, thereby reducing the efficiency of the hair dryer 200 and the user's experience.

[0066] Secondly, the first ridge 1211 extending in the length direction can provide a more uniform extrusion force, so that the seal can be more completely attached to the splicing surface, thereby improving the overall sealing performance. For example, if the first ridge 1211 extends in other directions, it may provide a stronger extrusion force in some areas, but it may be weaker in other areas, resulting in uneven sealing performance. At the same time, the extension of the first ridge 1211 in the length direction is conducive to increasing the contact area between the first ridge 1211 and the first seal 20, thereby making the connection between the first seal 20 and the second splicing surface 121 more secure. For example, when the dimensions of the first splicing surface 111 and the second splicing surface 121 are constant, if the first ridge 1211 extends in other directions, the contact area between the first ridge 1211 and the first seal 20 is small, and the first seal 20 cannot be completely attached to the first splicing surface 111, resulting in poor sealing effect.

[0067] In one embodiment, reference Figures 4 to 7 The first splicing surface 111 is provided with a first groove 112 corresponding to the first convex strip 1211 , and the first sealing member 20 is embedded in the first groove 112 ; when the first splicing surface 111 and the second splicing surface 121 are spliced, the first convex strip 1211 abuts against the first sealing member 20 in the first groove 112 .

[0068] In this embodiment, the first groove 112 is used to accommodate the first seal 20 and leave a fitting space for the first joint surface 111 and the second joint surface 121. The first groove 112 can extend along the length direction of the handle shell 10, and there is no restriction on the position where the first ridge 1211 abuts the first seal 20. By setting the first groove 112 corresponding to the first ridge 1211 on the first joint surface 111 and accurately embedding the first seal 20 in the groove, the accurate positioning and fixation of the seal is achieved. During assembly, it is only necessary to embed the first seal 20 in the first groove 112 in advance, and then align the first joint surface 111 with the second joint surface 121 for splicing, thereby reducing the air leakage problem caused by the misalignment or looseness of the first seal 20 and significantly improving the sealing effect of the equipment. Secondly, the cooperation between the first ridge 1211 and the first groove 112 not only enhances the connection strength of the joint surface, but also further stabilizes the position of the first seal 20 through the extrusion effect.

[0069] Furthermore, the first convex strip 1211 cooperates with the first groove 112 in a first direction, and the first direction, the length direction of the handle shell 10 and the splicing direction are perpendicular to each other.

[0070] In this embodiment, the first ridge 1211 cooperates with the first groove 112 in the first direction to provide an additional limiting effect for the splicing process of the first sub-shell 11 and the second sub-shell 12, thereby preventing the second sub-shell 12 from moving in the first direction. At the same time, the first ridge 1211 abuts against the side wall of the first groove 112 to increase the contact area between the first ridge 1211 and the first sub-shell 11, thereby enhancing the connection strength between the first sub-shell 11 and the second sub-shell 12 and improving the rigidity of the hair dryer 200.

[0071] In one embodiment, the connection between the first joint surface 111 and the outer circumference of the first subshell 11 is recessed to form a first groove 112 . The first groove 112 includes a first inner wall 1121 connected to the first joint surface 111 . The first convex strip 1211 abuts against the first inner wall 1121 in the first direction.

[0072] In this embodiment, the first joint surface 111 and the first groove 112 are in a two-step step shape. This structure provides a variety of ways for installing the first seal 20. For example, the first seal 20 can be installed in the first groove 112 along the first direction, or installed in the first groove 112 along the joint direction. When the first seal 20 is installed in the first groove 112 along the joint direction, the positioning of one wall surface can be reduced, thereby improving the installation efficiency. Secondly, the first seal 20 can extend out of the first groove 112 along the first direction, thereby increasing the width of the first seal 20, increasing the sealing area, and improving the sealing effect.

[0073] In one embodiment, the first subshell 11 has two first splicing surfaces 111, and the second subshell 12 has two second splicing surfaces 121. One of the first splicing surface 111 and the second splicing surface 121 is provided with a positioning groove 113, and the other is provided with a positioning column 122 adapted to the positioning groove 113; the first sealing member 20 is arranged to avoid the positioning groove 113, and the first convex strip 1211 is arranged to avoid the positioning column 122.

[0074] In the embodiment of the utility model, the first splicing surface 111 is provided with a positioning groove 113, and the second splicing surface 121 is provided with a positioning column 122, and the positioning column 122 can be cylindrical or square. The use of the positioning groove 113 and the positioning column 122 ensures that the first sub-shell 11 and the second sub-shell 12 can be accurately aligned when spliced, avoiding the occurrence of misalignment or offset. Secondly, by setting the first sealing member 20 at a position avoiding the positioning groove 113 and ensuring that the first convex strip 1211 avoids the positioning column 122, this design ensures that the sealing member will not be disturbed or damaged during the splicing process.

[0075] In one embodiment, the first splicing surface 111 includes a first abutting surface 114 and a first widening surface 115 connected to the first abutting surface 114, the first groove 112 is arranged on the first widening surface 115, the second splicing surface 121 is provided with a second widening surface 123 corresponding to the first widening surface 115, the first convex strip 1211 is arranged on the second widening surface 123, and the width of the first widening surface 115 is greater than the width of the first abutting surface 114.

[0076] In this embodiment, the widened surface provides sufficient space for the first groove 112, and can accommodate a larger first seal 20, thereby improving the sealing performance between the first sub-shell 11 and the second sub-shell 12. At the same time, the widened surface has a larger width, which increases the contact area between the first sub-shell 11 and the second sub-shell 12, thereby enhancing the stability of the splicing structure.

[0077] In one embodiment, the positioning groove 113 is disposed on the first widened surface 115 , and the peripheral wall surface of the positioning groove 113 partially protrudes from the first groove 112 along the first direction; the positioning column 122 is protruding from the second widened surface 123 and located inside the first protruding strip 1211 .

[0078] In this embodiment, the positioning column 122 is convexly arranged on the second widening surface 123, which helps to increase the structural rigidity of the positioning column 122. If it is arranged at other positions, the connection surface 124 of the positioning column 122 away from the positioning groove 113 is uneven, which causes the positioning column 122 to be easily broken when the hair dryer 200 is impacted or pressurized, thereby reducing the service life of the hair dryer 200. Secondly, the inner side refers to the side close to the middle position of the handle shell 10. The positioning column 122 is arranged on the inner side of the first convex strip 1211, which can further protect the positioning column 122 from being easily broken. If the positioning column 122 is located on the outside of the first convex strip 1211, the first positioning column 122 is closer to the outer surface of the handle shell 10, and the first positioning column 122 is easily broken when the handle shell 10 is impacted.

[0079] In one embodiment, reference Figures 3 to 7 The inner shell assembly 100 of the hair dryer also includes a cylinder shell 40 and a connecting piece 30 connected to the cylinder shell 40, and the top of the second sub-shell 12 is sealed and connected to the connecting piece 30; the connecting piece 30 is provided with a mounting notch 31, and the top of the first sub-shell 11 is connected to the side wall of the mounting notch 31 along the splicing direction; the first sub-shell 11 has two joint surfaces 116 connected to the side wall of the mounting notch 31, and the joint surface 116 is connected to the first splicing surface 111; the handle shell 10 is in the shape of a long cylinder, and the first sealing piece 20 includes a first sealing section 21 and a second sealing section 22 extending along the length direction of the handle shell 10, the first sealing section 21 is connected to the second sealing section 22, the second sealing section 22 is sandwiched between the first widening surface 115 and the second widening surface 123, and the first sealing section 21 is sandwiched between the side wall of the mounting notch 31 and the joint surface 116.

[0080] In this embodiment, for simplicity and beauty, the wind cylinder housing 40 is generally cylindrical or quasi-cylindrical. The connecting member 30 is used to connect the wind cylinder housing 40 and the handle housing 10. By setting the connecting member 30 and the wind cylinder housing 40 as a separate structure, the processing cost can be reduced compared to a structure in which the two are integrated. The installation notch 31 provided on the connecting member 30 provides a space for inserting and connecting the top of the first sub-shell 11.

[0081] The first sealing member 20 includes a first sealing section 21 and a second sealing section 22 extending along the length direction of the handle shell 10. The second sealing section 22 is sandwiched between the first joint surface 111 and the second joint surface 121. The first sealing section 21 is sandwiched between the side wall of the installation notch 31 and the joint surface 116, and at the same time ensures the sealing between the first sub-shell 11 and the second sub-shell 12 and the connector 30 respectively. This double sealing design significantly improves the overall air tightness of the inner shell assembly and reduces wind resistance and noise. Secondly, the connector 30 is provided with a mounting notch 31 for connecting the first sub-shell 11, so that the various parts of the inner shell assembly 100 of the hair dryer are closely matched and the structure is more compact.

[0082] Furthermore, a second convex strip 32 extending along the length direction of the handle shell 10 is protruded from the side wall of the installation notch 31 , and the second convex strip 32 abuts against and presses the first sealing section 21 .

[0083] In this embodiment, the second convex strip 32 extending in the length direction can apply a stronger and more uniform extrusion force to the first sealing section 21, so that the first sealing section 21 can be more completely attached to the joint surface 116 and deformed, thereby improving the overall sealing performance. For example, if the second convex strip 32 extends in other directions, it may provide a stronger extrusion force in some areas, but it may be weaker in other areas, resulting in uneven sealing performance. At the same time, the extension of the second convex strip 32 in the length direction is conducive to increasing the contact area between the second convex strip 32 and the first sealing section 21, so that the connection between the first sealing member 20 and the second joint surface 116 is more secure. For example, when the sizes of the first joint surface 116 and the second joint surface 116 are constant, if the second convex strip 32 extends in other directions, the contact area between the second convex strip 32 and the first sealing section 21 is small, and the first sealing member 20 cannot be completely attached to the first joint surface 116, resulting in poor sealing effect.

[0084] Furthermore, the joint surface 116 is recessed to form a second groove, and the first sealing section 21 is embedded in the second groove; the width of the first sealing section 21 is smaller than the width of the second sealing section 22 .

[0085] In this embodiment, the second groove is provided so that the first sealing section 21 has a storage space, and the first sealing section 21 can be accurately positioned and installed in the second groove, thereby improving assembly efficiency. Secondly, since the first sealing section 21 is connected to the side wall of the installation notch 31, the width of the first sealing section 21 determines the thickness of the side wall of the installation notch 31. The side wall thickness of the installation notch 31 is relatively small, which means that the thickness of the connector 30 is relatively small, which can reduce the weight of the connector 30, thereby reducing the weight of the hair dryer 200 and improving the user experience.

[0086] In one embodiment, the wall surface of the connecting member 30 facing away from the mounting notch 31 has a mounting arc surface 33, the mounting arc surface 33 is lower than the outer peripheral surface of the connecting member 30, and the second sub-shell 12 covers the mounting arc surface 33 along the splicing direction; the inner shell assembly 100 of the hair dryer also includes a second sealing member 50, which is embedded in the mounting arc surface 33 and clamped between the second sub-shell 12 and the connecting member 30.

[0087] In the present embodiment, the second sealing member 50 may be a sheet-like structure, and its material may be silicone, rubber or other materials with a sealing effect. By covering the top of the second sub-shell 12 in the installation arc surface 33, the contact area between the second sub-shell 12 and the inner wall of the installation arc surface 33 is increased, the stability of the connection is improved, and the movement of the second sub-shell 12 relative to the connector 30 in the first direction is limited. In addition, the setting of the installation arc surface 33 makes the positioning and installation of the second sub-shell 12 and the connector 30 simpler and faster, and the preliminary installation can be completed by simply covering the second sub-shell 12 in the installation arc surface 33. Secondly, the second sealing member 50 is embedded in the installation arc surface 33 and clamped between the second sub-shell 12 and the connector 30, which further improves the sealing between the second sub-shell 12 and the connector 30.

[0088] Furthermore, the second sub-shell 12 also includes two connecting surfaces 124 respectively connected to the two second splicing surfaces 121, and the connecting surfaces 124 cooperate with the second sealing member 50; the connecting surface 124 is provided with a third ridge 125 extending along the length direction of the handle shell 10, and the third ridge 125 is connected to the first ridge 1211, and the third ridge 125 abuts against and squeezes the second sealing member 50.

[0089] In this embodiment, the connection surface 124 is used to cooperate with the second sealing member 50 and is connected to the connection member 30. By making the connection surface 124 and the second sealing member 50 closely cooperate, it is ensured that an effective sealing layer is formed between the two to prevent airflow, moisture or other impurities from leaking therefrom. Secondly, the provision of the third ridge 125 can increase the contact pressure between it and the second sealing member 50, causing the second sealing member 50 to deform, thereby more effectively sealing the connection member 30 and the second sub-shell 12.

[0090] Furthermore, the third convex strip 125 includes a transverse extension section 1251 and a longitudinal extension section 1252 , the transverse extension section 1251 connects the longitudinal extension section 1252 and the first convex strip 1211 , and the longitudinal extension section 1252 is recessed relative to the first convex strip 1211 in the splicing direction.

[0091] In the present embodiment, the third ridge 125 and the first ridge 1211 are integrally stepped, so that each contact surface where the second subshell 12 is connected to the connector 30 has the third ridge 125 abutting against the seal, so as to improve the sealing between the second subshell 12 and the connector 30. In other words, through the design of the transverse extension section 1251 and the longitudinal extension section 1252, the third ridge 125 applies an extrusion force to the second seal 50 in different directions, so that the second seal 50 can be stressed and deformed in multiple directions, thereby increasing the sealing effect. Secondly, the concave setting of the longitudinal extension section 1252 relative to the first ridge 1211 in the splicing direction provides a natural alignment and guiding function, so that during the installation process, the second subshell 12 and the connector 30 can be more accurately aligned, thereby improving the assembly accuracy and efficiency and reducing installation errors.

[0092] Further, refer to Fig. 9 The second sealing member 50 is provided with two protrusions 51 along the first direction; the mounting arc surface 33 includes a splicing surface 36 spliced ​​with the connecting surface 124, and the connection between the splicing surface 36 and the outer peripheral surface of the connecting member 30 is recessed to form two third grooves 35, and the second sealing member 50 is embedded in the third grooves 35; the connecting member 30 is provided with a mounting hole 34 at a position adjacent to the third groove 35, and the second sub-shell 12 is provided with a mounting column 127 corresponding to the mounting hole 34, and the protrusion 51 abuts against the mounting column 127 in the first direction; the first direction, the length direction of the handle shell 10 and the splicing direction are perpendicular to each other.

[0093] In this embodiment, the joint surface 36 and the third groove 35 are stepped as a whole. Since the mounting hole 34 is opened at the position of the connecting member 30 near the third groove 35, a gap is formed between the side wall of the mounting hole 34 and the side wall of the third groove 35. The protrusion 51 is used to fill the gap and abut against the mounting column 127, which effectively avoids air leakage, ensures the sealing at the gap, enhances the overall airtightness, and reduces wind resistance and noise.

[0094] In one embodiment, the inner shell assembly 100 of the hair dryer also includes a third seal 60 integrally formed with the second seal 50, the third seal 60 is arc-shaped, and is embedded in the mounting arc surface 33; the third seal 60 is adapted to the inner wall surface of the second sub-shell 12; the inner wall surface of the second sub-shell 12 is provided with a fourth ridge 126 corresponding to the third seal 60, and the fourth ridge 126 abuts and squeezes the third seal 60.

[0095] In the present embodiment, the second seal 50 can be a sheet structure, and its material can be silicone, rubber or other materials with sealing effect. The third seal 60 is integrally formed with the second seal 50, ensuring seamless connection between the two seals and avoiding the problem of poor sealing due to the split structure. The arc-shaped third seal 60 is embedded in the outer peripheral wall of the connector 30, so that the inner wall surface of the second sub-shell 12 is in close contact with the third seal 60, thereby further improving the overall sealing performance of the inner shell assembly. Secondly, the fourth convex strip 126 abuts and squeezes the third seal 60. This design provides additional squeezing force, so that the third seal 60 forms an effective seal between the outer peripheral wall of the connector 30 and the inner wall surface of the second sub-shell 12. This can greatly reduce air leakage, thereby reducing the wind noise of the hair dryer 200 when it is working and improving the comfort of the user when using it.

[0096] In one embodiment, the first sub-shell 11 includes a main body 118 extending along the length direction of the handle shell 10 and a plug-in portion 117 protruding from one end of the main body 118, and the end of the main body 118 close to the plug-in portion 117 is spliced ​​with the peripheral side wall of the installation notch 31; the inner shell assembly 100 of the hair dryer also includes a fourth sealing member 70, which is embedded in the plug-in portion 117 and clamped between the plug-in portion 117 and the connector 30; the fourth sealing member 70 includes a circumferential extension section 71 and a radial extension section 72, and the circumferential extension section 71 and the radial extension section 72 are integrally formed.

[0097] In this embodiment, by inserting the plug-in portion 117 into the installation notch 31, the contact area between the two is increased, thereby improving the mechanical strength and stability of the connection and reducing the looseness or displacement caused by external forces. Secondly, the plug-in portion 117 provides a clear alignment and connection position, making the assembly process simpler and faster. By inserting the plug-in portion 117 into the installation notch 31, the initial assembly can be completed quickly, thereby improving production efficiency.

[0098] The fourth sealing member 70 may be a sheet-like structure, and its material may be silicone, rubber or other materials with a deformable sealing effect. The fourth sealing member 70 is embedded in the plug-in portion 117 and sandwiched between the plug-in portion 117 and the connector 30, ensuring a tight seal between the plug-in portion 117 and the connector 30. The fourth sealing member 70 includes a longitudinal extension section and a radial extension section 72, providing sealing effects in different directions, thereby improving the overall sealing performance.

[0099] Please refer to Figure 1 and Figure 2The utility model also proposes a hair dryer 200, which includes a fan assembly 80 and a hair dryer 200. The specific structure of the hair dryer 200 refers to the above embodiment. Since the hair dryer 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the fan assembly 80 is arranged in the handle shell 10. The main function of the fan assembly 80 is to generate a strong airflow through rotation. The impeller is driven to rotate by the motor, and the air is sucked in and blown out through the air duct to achieve the functions of drying and styling.

[0100] In one embodiment, the inner shell assembly 100 of the hair dryer also includes a wind tube connected to the handle shell 10; the handle shell 10 includes an air outlet section 14 and an air inlet section 13, the air outlet section 14 is close to the wind tube, the fan assembly 80 is arranged in the air inlet section 13, and the first sealing member 20 of the inner shell assembly 100 of the hair dryer is arranged in the air outlet section 14.

[0101] By sealing the air outlet section 14, air leakage in the air duct is avoided, and the working efficiency and performance of the hair dryer 200 are improved. At the same time, the noise generation is reduced, and the user experience is improved. Secondly, since the fan assembly 80 is arranged in the air inlet section 13 of the handle shell 10, the air flow path inside the hair dryer 200 is optimized, ensuring that the air can smoothly pass through the fan assembly 80 into the air cylinder, thereby improving the efficiency of the hair dryer 200. The design of the air outlet section 14 close to the air cylinder enables the hair dryer 200 to output airflow quickly and effectively, thereby improving the effect of drying and styling hair.
