Description

Technical Field

[0001] This application falls under the category of small household appliances, specifically relating to a hair dryer. Background Technology

[0002] To enhance the human-computer interaction experience, high-speed hair dryers are equipped with display components, which are commonly located on the side or end of the hair dryer body.

[0003] For example, existing patent CN202222409625.6 discloses a hair dryer in which the display component is located at the air inlet end of the body, providing a better user experience. Specifically, the air inlet end includes an air inlet carrier, a support, a first enclosure, and an air inlet cover. At least a portion of the display component is located in the space between the support and the first enclosure. Although the multiple structural components fit together tightly, the large number of components makes the configuration relatively complex and increases the assembly workload, potentially leading to an oversized axial dimension of the body. Furthermore, the display component includes a circuit board, and a connector is provided between the first enclosure and the circuit board for supporting and fixing the circuit board, further increasing the number of structural components and resulting in a complex overall structure. Utility Model Content

[0004] This application provides a hair dryer designed to solve the technical problems of existing hair dryers with display components having complex structures and inconvenient installation of the display components.

[0005] The technical solution adopted in this application is as follows:

[0006] A hair dryer includes a body and a handle. The body contains a fan, and the rear of the body has an air inlet corresponding to the fan. The air inlet includes an air inlet bracket and an air inlet cover extending from the inside to the outside. The side of the air inlet bracket forms an air inlet area for air to enter the fan. The outer end of the air inlet bracket has a mounting cavity, and a display component is disposed within the mounting cavity. The end face of the air inlet cover has a window corresponding to the display component, so that the display component is exposed to the outside through the window.

[0007] The hair dryer of this application, with the display component located at the rear of the body to meet the human-computer interaction requirements, can make the side of the body more concise. The display component is integrated on the air inlet bracket, eliminating the need for additional installation parts. The number of structural components involved is small, making installation easy. Moreover, the display component is sandwiched between the air inlet bracket and the air inlet cover, which can promote the compact layout of the structure without increasing the axial dimension of the body, which is conducive to the miniaturization of the hair dryer.

[0008] The air intake bracket of this application not only provides an air intake area, but also integrates the installation of display components and air intake cover. It is multi-functional and eliminates the need for additional structures, achieving the function of integrating display and air intake in one unit. This greatly simplifies the configuration of the hair dryer and helps to reduce costs.

[0009] Optionally, the display assembly includes a display screen and a support member, the support member being snap-fitted to the inner wall of the mounting cavity to clamp the display screen.

[0010] In this technical solution, the built-in support of the display component can support and limit the position of the display screen, which can improve the installation reliability of the display screen and ensure that the display screen maintains a stable vertical posture to provide users with a good display angle and improve the user's visual effect. In addition, no additional structure is required at the window of this technical solution. Users can directly view the display content through the hollowed-out window, which is more convenient for clear viewing and improves the user experience.

[0011] Optionally, the display component includes a display screen, and the window has a transparent panel, the side of the panel facing the display screen abutting against the display screen within the mounting cavity.

[0012] In this technical solution, the display components are simply configured. The window panel can be reused to support the display screen, ensuring that the display screen is securely installed. At the same time, the closed and perforated window panel can prevent dust, foreign objects, liquids, etc. from contacting the display screen through the window and affecting its cleanliness, display effect and service life.

[0013] Optionally, the inner end of the air inlet bracket is provided with a sound-absorbing plate that extends vertically to correspond to the fan, and the sound-absorbing plate is provided with multiple sound-absorbing holes.

[0014] In this technical solution, the air inlet bracket also integrates a noise reduction structure, which further expands the function of the air inlet bracket. When the fan is working, multiple silencers can absorb the fan noise, which can reduce the noise transmitted to the outside of the blower and improve the user experience.

[0015] Optionally, the sound-absorbing plate is spaced apart from the bottom wall of the mounting cavity.

[0016] In this technical solution, the sound-absorbing plate is spaced apart from the bottom wall of the mounting cavity, and an air gap is formed between the sound-absorbing plate and the bottom wall of the mounting cavity. This air gap is also conducive to consuming the noise propagation energy, thus further reducing the noise transmitted to the outside of the blower.

[0017] Optionally, the bottom wall of the mounting cavity and the sound-absorbing plate are provided with a communicating cable passage.

[0018] In this technical solution, by setting a wire passage, the wiring of the display component can be extended into the body through the wire passage and further extended into the handle to connect with the control board, which optimizes the wiring layout and does not affect the air intake, thus ensuring the air intake performance of the blower.

[0019] Optionally, the air inlet end of the fan is provided with an air guide shroud, the air guide shroud includes an annular first sound insulation part, the air inlet bracket is provided with an annular second sound insulation part, the second sound insulation part is located radially outside the first sound insulation part, the second sound insulation part and the first sound insulation part are spaced apart and partially overlap in the axial direction of the machine body.

[0020] In this technical solution, the second and first sound insulation sections are staggered. The advantage of this arrangement is that fan noise cannot propagate directly to the outside of the blower in a straight line; the noise intensity is significantly reduced after multiple reflections, thus reducing the amount of noise transmitted to the outside of the blower. The second and first sound insulation sections partially overlap, requiring noise to be reflected multiple times by the baffles before reaching the outside of the blower, effectively reducing the propagation of fan noise.

[0021] Optionally, the air inlet hood has an air inlet hole on its peripheral wall, a first channel is formed between the air inlet hole and the second sound insulation part, a second channel is formed between the second sound insulation part and the first sound insulation part, and the air guide hood has an air inlet on the radially inner side of the first sound insulation part. The first channel, the second channel and the air inlet are connected in sequence to form a zigzag channel.

[0022] In this technical solution, when the hair dryer is working, the noise generated by the fan propagates along the zigzag channel. The long propagation path helps to dissipate noise energy to a greater extent, resulting in very little noise reaching the outside of the hair dryer and improving noise reduction performance. Furthermore, the zigzag channel also helps prevent dust, liquids, and other contaminants from entering the machine body, thus extending the service life of internal components.

[0023] Optionally, the air inlet bracket is provided with a sound-absorbing plate, and the second sound insulation part is arranged around the sound-absorbing plate. The second sound insulation part and the sound-absorbing plate are an integral structure and are snap-fitted to the inner end of the air inlet bracket.

[0024] In this technical solution, the second sound insulation section and the sound-absorbing plate adopt an integrated structure, which facilitates installation with the air inlet bracket and simplifies the installation process.

[0025] Optionally, the air inlet area is provided with a plurality of spaced support ribs along the circumferential direction, and the air inlet part further includes a filter screen disposed between the air inlet bracket and the air inlet hood, the filter screen covering the outer surface of the plurality of support ribs.

[0026] In this technical solution, by setting up a filter, the amount of dust and dirt entering the machine body can be reduced, allowing the incoming air to be filtered before entering the machine body, and ensuring the normal use of the blower. The filter is integrated into the air intake bracket, which further expands the function of the air intake bracket. The filter is supported by multiple support ribs, which can reduce the risk of deformation, thereby ensuring the air intake filtration effect. Attached Figure Description

[0041] like Figures 1 to 6 As shown, this application provides a hair dryer, including a body 10 and a handle 11. The body 10 is provided with a fan 12. The rear of the body 10 is provided with an air inlet corresponding to the fan 12. The air inlet includes an air inlet bracket 13 and an air inlet cover 14 from the inside to the outside. The side of the air inlet bracket 13 forms an air inlet area 131 for air to enter the fan 12. The outer end of the air inlet bracket 13 is provided with a mounting cavity 132. The mounting cavity 132 is provided with a display component 15. The end face of the air inlet cover 14 is provided with a window 141 corresponding to the display component 15, so that the display component 15 is exposed to the outside through the window 141.

[0042] The hair dryer of this application, with the display component 15 located at the rear of the body 10 to meet the human-computer interaction requirements, can make the side of the body 10 more concise. The display component 15 is integrated on the air inlet bracket 13, eliminating the need for additional mounting parts 134. The number of structural components involved is small, making installation easier. Moreover, the display component 15 is sandwiched between the air inlet bracket 13 and the air inlet cover 14, which can promote a compact layout of the structure without increasing the axial dimension of the body 10, which is conducive to the miniaturization of the hair dryer.

[0043] The air intake bracket 13 of this application not only provides an air intake area 131, but also integrates the installation of a display component 15 and an air intake cover 14. It is multi-functional and eliminates the need for additional structures, achieving the function of integrating display and air intake, which greatly simplifies the configuration of the hair dryer and helps to reduce costs.

[0044] Specifically, the body 10 includes a casing, and the air inlet bracket 13 is fixed to the casing, for example, by screws. The air inlet shroud 14 is fitted onto the side of the air inlet bracket 13. For example, the side of the air inlet bracket 13 has a slot 133, and the inner wall of the air inlet shroud 14 has a buckle 142, and the two are snapped together. Figure 1 As shown, the air intake shroud 14 has an air intake hole 143 on its peripheral wall. External air enters the body 10 through the air intake area 131 via the air intake hole 143. The air intake area 131 has multiple arc-shaped air intakes along the circumference, which can meet the air intake requirements. Thus, the air intake part takes in air from the side, which does not conflict with the display component 15 at the end, and realizes the integration of air intake and display functions.

[0045] The air inlet bracket 13 has an annular portion extending axially along the body 10 and a mounting portion 134 extending vertically inside the annular portion. The mounting portion 134 is located at one end of the annular portion near the air inlet shroud 14 and forms the bottom wall of the mounting cavity 132, which can isolate the display component 15 from the fan 12 and reduce the vibration caused to the display component 15 during the operation of the fan 12. The display component 15 is sandwiched between the mounting portion 134 and the air inlet shroud 14 and is arranged vertically. The user can view the content displayed on the display component 15 through the perforated window 141.

[0046] The handle 11 is equipped with a power button 16 and a function adjustment key 17. The user can control the airflow of the hair dryer through the power button 16 and adjust the air speed, temperature, and display content through the function adjustment key 17. To facilitate users in adjusting and viewing simultaneously, it is preferable that the function adjustment key 17 and the display component 15 are located on the same side, which can improve ease of use.

[0047] In a preferred embodiment of this application, the display assembly 15 includes a display screen 18 and a support member 19, wherein the support member 19 is snapped into the inner wall of the mounting cavity 132 to clamp the display screen 18.

[0048] In this technical solution, the support component 19 built into the display component 15 can support and limit the display screen 18, which can improve the installation reliability of the display screen 18 and ensure that the display screen 18 maintains a stable vertical posture to provide users with a good display angle and improve the user's visual effect. In addition, no additional structure is required at the window 141 of this technical solution. Users can directly view the display content through the hollow window 141, which is more convenient for clear viewing and improves the user experience.

[0049] like Figure 1 As shown, the support member 19 is provided with a protruding buckle 191, and the mounting cavity 132 is provided with a slot for receiving the protruding buckle 191, which can fix the support member 19. The display screen 18 is provided with a clearance part 181 at the position corresponding to the protruding buckle 191 to avoid installation interference. The support member 19 adopts a transparent structure to ensure that the content of the display screen 18 can be exposed through the window 141.

[0050] In a preferred embodiment of this application, the display component 15 includes a display screen 18, and a window 141 is provided with a transparent window plate, the side of the window plate facing the display screen 18 abutting against the display screen 18 within the mounting cavity 132.

[0051] In this embodiment, the configuration of the display component 15 is simple, and the support component 19 can be omitted. The window panel can be reused to support the display screen 18, ensuring that the display screen 18 is installed firmly. At the same time, the window panel closes the hollowed-out window 141, which can prevent dust, foreign objects, liquids, etc. from contacting the display screen 18 through the window 141 and affecting its cleanliness, display effect and service life.

[0052] As a preferred embodiment of this application, the inner end of the air inlet bracket 13 is provided with a sound-absorbing plate 20 that extends vertically in relation to the fan 12, and the sound-absorbing plate 20 is provided with a plurality of sound-absorbing holes 201.

[0053] like Figure 2 As shown, the air inlet bracket 13 also integrates a noise reduction structure, which further expands the function of the air inlet bracket 13. When the fan 12 is working, multiple silencers 201 can absorb the noise of the fan 12, which can reduce the noise transmitted to the outside of the blower and improve the user experience.

[0054] Preferably, the equivalent diameter of the area where the silencing holes 201 are arranged on the silencing plate 20 is D1, and the diameter of the fan 12 is D2, where D1 > 1.2D2. This size limitation can ensure that most of the noise generated by the fan 12 can be reflected by the silencing plate 20, thus ensuring the noise reduction effect of the silencing plate 20.

[0055] In one embodiment, the sound-absorbing plate 20 is spaced apart from the bottom wall of the mounting cavity 132.

[0056] In this technical solution, the sound-absorbing plate 20 is spaced apart from the bottom wall of the mounting cavity 132, and an air gap is formed between the sound-absorbing plate 20 and the bottom wall of the mounting cavity 132. This air gap is also conducive to consuming the noise propagation energy, thus further reducing the noise transmitted to the outside of the blower.

[0057] like Figure 4 As shown, the gap between the sound-absorbing plate 20 and the mounting part 134 is L, the thickness of the sound-absorbing plate 20 is t, the diameter of the sound-absorbing hole 201 is d, and the hole spacing is B. By optimizing these parameters, the resonant frequency of the sound-absorbing plate 20 can be set to correspond to the frequency of the fan 12, which is beneficial to reduce the peak noise of the blower and reduce the overall noise of the machine.

[0058] In another embodiment, the bottom wall of the mounting cavity 132 and the sound-absorbing plate 20 are provided with a communicating wire passage 21.

[0059] like Figure 1 or Figure 2 As shown, by setting the wire passage 21, the wiring of the display component 15 can be extended into the body 10 through the wire passage 21 and further extended into the handle 11 to connect with the control board, which optimizes the wiring layout and does not affect the air intake, thus ensuring the air intake performance of the hair dryer.

[0060] As a preferred embodiment of this application, the air inlet end of the fan 12 is provided with an air guide shroud, which includes an annular first sound insulation part 22. The air inlet bracket 13 is provided with an annular second sound insulation part 23. The second sound insulation part 23 is located radially outside the first sound insulation part 22. The second sound insulation part 23 and the first sound insulation part 22 are spaced apart and partially overlap in the axial direction of the body 10.

[0061] like Figure 3 As shown, the second sound insulation part 23 and the first sound insulation part 22 are staggered. This has the advantage that the noise from the fan 12 cannot propagate directly to the outside of the blower in a straight line; the noise intensity is significantly reduced after multiple reflections, thus reducing the amount of noise transmitted to the outside of the blower. The second sound insulation part 23 and the first sound insulation part 22 partially overlap, so the noise must be reflected multiple times by the baffles before it can propagate to the outside of the blower, effectively reducing the propagation of the fan 12 noise. Preferably, the overlap length of the second sound insulation part 23 and the first sound insulation part 22 is S, where 1mm < S < 10mm.

[0062] In one embodiment, the air inlet shroud 14 has an air inlet hole 143 on its peripheral wall, a first channel 24 is formed between the air inlet hole 143 and the second sound insulation part 23, a second channel 25 is formed between the second sound insulation part 23 and the first sound insulation part 22, and an air guide shroud is provided with an air inlet 26 on the radial inner side of the first sound insulation part 22. The first channel 24, the second channel 25 and the air inlet 26 are connected in sequence to form a zigzag channel.

[0063] Figure 3The diagram illustrates the airflow path along the zigzag channel. It's understood that the noise propagation path is exactly the opposite. When the blower is operating, the noise generated by the fan 12 propagates along the zigzag channel. This long propagation path helps to dissipate noise energy to a greater extent, resulting in very little noise reaching the outside of the blower and improving noise reduction performance. Furthermore, the zigzag channel also helps prevent dust, liquids, etc., from entering the interior of the unit 10, thus extending the service life of the internal components.

[0064] Preferably, the area of ​​the annular air duct formed between the stator and the fan casing of the fan 12 is smaller than the area of ​​the annular air duct formed between the second sound insulation part 23 and the first sound insulation part 22. This reduces the intake resistance and lowers the load on the fan 12 when airflow enters the annular air duct between the stator and the fan casing from the annular air duct between the second sound insulation part 23 and the first sound insulation part 22, ensuring smooth airflow and improving the air output efficiency of the blower. Figure 5 As shown, the inner diameter of the fan casing is D2, the outer diameter of the stator of the fan 12 is D3, the inner diameter of the second sound insulation part 23 is D4, and the outer diameter of the first sound insulation part 22 is D5. Setting ((D4 / 2)(-(D5 / 2)()*π>((D2 / 2)(-(D3 / 2)()*π) can ensure smooth air intake.

[0065] In another embodiment, the air inlet bracket 13 is provided with a sound-absorbing plate 20, and a second sound-insulating part 23 is arranged around the sound-absorbing plate 20. The second sound-insulating part 23 and the sound-absorbing plate 20 are an integral structure and are snapped together to the inner end of the air inlet bracket 13.

[0066] like Figure 6 As shown, the second sound insulation section 23 and the sound-absorbing plate 20 adopt an integrated structure, which facilitates installation with the air inlet bracket 13 and simplifies the installation process. In addition, the integrated structure formed by the second sound insulation section 23 and the sound-absorbing plate 20 adopts a snap-fit ​​installation, which facilitates disassembly, cleaning or maintenance, and is convenient to use.

[0067] In a preferred embodiment of this application, the air inlet area 131 is provided with a plurality of spaced support ribs 135 along the circumferential direction. The air inlet also includes a filter screen (not shown in the figure) disposed between the air inlet bracket 13 and the air inlet hood 14, and the filter screen covers the outer surface of the plurality of support ribs 135. An arc-shaped air inlet is formed between adjacent support ribs 135.

[0068] In this technical solution, by setting up a filter, the amount of dust and dirt entering the machine body can be reduced, and the incoming air can be filtered before entering the machine body 10, which can ensure the cleanliness of the outgoing air and ensure the normal use of the blower. The filter is integrated on the air inlet bracket 13, which further expands the function of the air inlet bracket 13. The filter is supported by multiple support ribs 135, which can reduce the risk of deformation, thereby ensuring the air inlet filtration effect.

[0069] Specifically, during processing, long strips of filter screen can be cut out, placed in an annular mold, and then integrally injection molded with the air inlet bracket 13; or, the filter screen can be welded and fixed around the air inlet area 131. This application does not make specific limitations on this.

[0071] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0072] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
