Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a care device. Background Technology

[0002] Hair dryers are a common household appliance, primarily used for drying and styling hair. They are also widely used in laboratories, physiotherapy rooms, industrial production, and art settings for localized drying, heating, and therapeutic purposes. Hot hair dryers, in particular, are used for a variety of purposes, such as drying substances (like paint and hair) and cleaning or peeling surface layers.

[0003] In related technologies, the motor of a hair dryer is located inside the handle. The motor vibrates during operation, and to reduce the amount of vibration transmitted to the handle housing, a shock-absorbing sleeve is typically wrapped around the outside of the motor, forming a motor assembly. This motor assembly is then further mounted on the inner shell of the handle, which has pre-installed mounting positions for the motor assembly. Finally, an outer handle shell is fitted over the inner handle shell, thus forming the complete handle structure. While this design satisfies the need for shock absorption, the numerous parts in the handle result in a large handle diameter, making it difficult to grip, and also lead to a complex handle structure and difficult assembly.

The air intake area is located upstream of the air inlet, and noise reduction cotton is set at the bottom of the air intake area.

[0037] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0038] The following is for reference. Figures 1-10 This invention describes a nursing appliance 100 according to an embodiment of the present invention. For example, the nursing appliance 100 may be a hair dryer, etc.

[0039] Reference Figures 1-5 As shown, the nursing device 100 according to the first aspect of the present invention includes: a shell 10, an inner shell 20 and a fan assembly 30. The inner shell 20 is disposed inside the shell 10 and has an air duct 24. The fan assembly 30 is disposed inside the inner shell 20. A shock-absorbing part 221 is provided on the inner wall of the inner shell 20, and the fan assembly 30 abuts against the shock-absorbing part 221.

[0040] Understandably, the outer shell 10, inner shell 20, and fan assembly 30 constitute the main structure of the care appliance 100. The outer shell 10 is fitted around the outer periphery of the inner shell 20, thus protecting the inner shell 20 and extending its service life. It also makes it easier for the user to grip the outer shell 10, facilitating the use of the care appliance 100. The inner shell 20 has an internal cavity forming an air duct 24, allowing airflow through and restricting its direction. The fan assembly 30 is located inside the inner shell 20, guiding the airflow towards the user.

[0041] The inner shell 20 has a shock-absorbing part 221 on its inner wall, which protrudes towards the center of the inner shell 20. The fan assembly 30 is located behind the inner shell 20 and abuts against the shock-absorbing part 221. This allows the shock-absorbing part 221 to dampen the vibration of the fan assembly 30, thereby improving the user's comfort when using the nursing device 100. Furthermore, the shock-absorbing part 221 is integrated into the inner wall of the inner shell 20, which reduces the overall size of the nursing device 100, lowers the assembly difficulty, and saves on material costs. This allows for a lightweight design and makes the nursing device 100 easier to carry. For example, the diameter of the nursing device 100 can be reduced by 2-3 mm.

[0042] Therefore, the inner wall of the inner shell 20 in the nursing device 100 is provided with a shock-absorbing part 221, so that the shock-absorbing part 221 and the inner shell 20 can be manufactured as an integrated unit, thereby reducing the complexity of the interior of the inner shell 20. The inner shell 20 is located inside the outer shell 10, and an air duct 24 is formed on the inner side of the inner shell 20. The fan assembly 30 is located in the inner shell 20, so that the air generated by the fan assembly 30 can be blown out through the air duct 24. Moreover, the fan assembly 30 abuts against the shock-absorbing part 221, so that the shock-absorbing part 221 can reduce the vibration of the fan assembly 30, thereby reducing the vibration of the nursing device 100 and facilitating the assembly of the nursing device 100.

[0043] Among them, such as Figures 2-5 As shown, the inner shell 20 includes: a first sub-shell 21, a second sub-shell 22, and a third sub-shell 23. The first sub-shell 21 includes an air inlet 211 that communicates with the air duct 24. One end of the second sub-shell 22 is connected to the first sub-shell 21, and the second sub-shell 22 is located downstream of the first sub-shell 21. One end of the third sub-shell 23 is connected to the second sub-shell 22, and the third sub-shell 23 is located downstream of the second sub-shell 22. A shock-absorbing part 221 is provided on the inner wall of the second sub-shell 22.

[0044] In other words, the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23 constitute the main structure of the inner shell 20. The first sub-shell 21, the second sub-shell 22, and the third sub-shell 23 are connected sequentially from downstream to upstream, which facilitates the assembly of the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23. Moreover, a shock-absorbing part 221 is provided on the inner wall of the second sub-shell 22, which abuts against the fan assembly 30. This allows the fan assembly 30 to be located inside the second sub-shell 22, which not only reduces the vibration transmission of the fan assembly 30 but also allows the fan assembly 30 to guide the airflow, thereby saving the airflow transmission path and optimizing the airflow transmission efficiency.

[0045] Furthermore, such as Figure 2 and Figure 4As shown, the second sub-shell 22 is detachably installed on the first sub-shell 21, and the third sub-shell 23 is detachably installed on the second sub-shell 22. It is understood that the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23 are mutually detachable. This allows the fan assembly 30 to be installed inside the second sub-shell 22, with the first sub-shell 21 and the third sub-shell 23 respectively installed at opposite ends of the second sub-shell 22. Disassembly is performed in reverse order, thereby optimizing the assembly process between the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23, and thus simplifying the installation time of the care appliance 100.

[0046] In addition, such as Figure 2 and Figure 4 As shown, the first sub-shell 21 and the second sub-shell 22 are screwed or snapped together, and the second sub-shell 22 and the third sub-shell 23 are screwed or snapped together. That is, the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23 can be screwed or snapped together with each other. This allows the fan assembly 30 to be installed inside the second sub-shell 22, with the first sub-shell 21 and the third sub-shell 23 screwed or snapped onto both ends of the second sub-shell 22 respectively. Disassembly is performed in reverse order, thus optimizing the assembly process between the first sub-shell 21, the second sub-shell 22, and the third sub-shell 23, thereby saving installation time for the nursing device 100. For example, the first sub-shell 21 and the second sub-shell 22 are connected using screws 25, and the second sub-shell 22 and the third sub-shell 23 are connected using clips 26.

[0047] Optionally, such as Figure 5 As shown, the second sub-shell 22 is made of hard plastic, and the shock-absorbing part 221 is made of soft plastic. The second sub-shell 22 and the shock-absorbing part 221 are integrally formed. The shock-absorbing part 221 is constructed as multiple shock-absorbing strips 222 extending along the inner shell 20. The multiple shock-absorbing strips 222 are distributed at intervals in the circumferential direction of the second sub-shell 22.

[0048] Understandably, the second sub-shell 22 and the shock-absorbing part 221 are integrally molded, that is, the soft rubber material is plasticized on the hard rubber material. This not only facilitates the manufacturing of the second sub-shell 22, but also facilitates the shock-absorbing part 221 to dampen the fan assembly 30. Moreover, the shock-absorbing part 221 is composed of multiple shock-absorbing strips 222, which are arranged circumferentially along the inner wall of the inner shell 20. The length of the shock-absorbing strips 222 extends along the length direction of the second sub-shell 22. This allows the shock-absorbing strips 222 to abut against the fan assembly 30, thereby reducing the transmission of vibration of the fan assembly 30 and improving the comfort of the care device 100.

[0049] In addition, such as Figure 3 and Figure 5 As shown, the second sub-shell 22 is provided with a limiting part 223, which is located at one end of the fan assembly 30 adjacent to the first sub-shell 21, and the limiting part 223 is axially limited and engaged with the fan assembly 30 along the inner shell 20.

[0050] In other words, a limiting part 223 is provided on the second sub-shell 22. The limiting part 223 is located at the end of the first sub-shell 21 near the fan assembly 30, and the limiting part 223 is axially limited and matched with the inner shell 20. This facilitates the limiting part 223 in limiting the fan assembly 30, thereby facilitating the placement of the fan assembly 30 within the second sub-shell 22 and improving the assembly efficiency of the nursing device 100. For example, the limiting part 223 can be a limiting platform that protrudes towards the center of the second sub-shell 22, thus facilitating the limiting platform in limiting the fan assembly 30.

[0051] In addition, such as Figure 1 and Figure 2 As shown, the outer casing 10 is provided with a button hole 11, and the second sub-casing 22 is provided with a button groove 224. The nursing device 100 also includes a button 40, which is disposed in the button groove 224 and passes through the button hole 11. It can be understood that the button hole 11 is provided on the outer casing 10, and the button groove 224 is provided on the second sub-casing 222. The button hole 11 and the button groove 224 are arranged opposite to each other, and the button groove 224 and the button hole 11 can limit the movement of the button 40. This facilitates the placement of the button 40 at the button groove 224 and the button hole 11, allowing the user to operate the button 40 to control the airflow direction of the fan assembly 30.

[0052] In addition, such as Figure 6 As shown, the nursing device 100 also includes: a filter and noise-reducing cotton 50. The filter defines an air inlet area 212, which is located upstream of the air inlet 211. The noise-reducing cotton 50 is disposed at the bottom of the air inlet area 212 and is spaced apart from the filter. There are two pieces of noise-reducing cotton 50, which are parallel to each other.

[0053] In other words, the filter defines the air inlet area 212, which is located upstream of the air inlet 211. This allows the airflow to flow into the air duct 24 after being filtered by the filter. The noise-reducing cotton 50 is located at the bottom of the air inlet area 212, and the noise-reducing cotton 50 and the filter are spaced apart. This allows the noise-reducing cotton 50 to comb and reduce the noise of the airflow as it is about to enter the air inlet area 212, thereby maximizing the passage of the airflow through the filter and reducing the noise of the airflow. The two pieces of noise-reducing cotton 50 are arranged in parallel and spaced apart, so that the noise-reducing cotton 50 can comb and reduce the noise of the airflow in different directions, thereby covering a large area of ​​airflow and improving the comfort of the nursing device 100.

[0054] In addition, such as Figure 7 and Figure 8As shown, the fan assembly 30 includes a motor 31 and a fan blade 32. The outer wall of the motor 31 abuts against the shock absorber 221. The fan blade 32 is rotatably connected to the motor 31 and is driven to rotate by the motor 31 to generate airflow. The fan blade 32 includes a plurality of circumferentially distributed blades, and at least one blade has a circumferential edge forming a cutting edge 33 for cutting hair.

[0055] It is understandable that the motor 31 and the fan blade 32 constitute the main structure of the fan assembly 30. The outer wall of the motor 31 abuts against the shock absorber 221, so that the vibration generated by the motor 31 can be reduced by the shock absorber 221. The power of the motor 31 is transmitted to the fan blade 32, and then the fan blade 32 rotates. Finally, the fan blade 32 generates airflow. The fan blade 32 is composed of multiple blades, which are circumferentially spaced and connected to the motor 31 at one end and extend away from the motor 31 at the other end, so as to ensure the flow of airflow. Moreover, at least one blade has a chamfered edge 33 on its circumferential edge, which can cut foreign objects and impurities when the blade rotates at high speed. This allows the blade to cut hair into pieces, and the hair pieces are blown out with the air duct 24, so that the hair does not get tangled on the blade, which can ensure the normal operation of the care device 100 and prevent the fan blade 32 from blocking. This can improve the service life of the care device 100 and the user experience. For example, the angle of the chamfer can be adjusted according to the airflow and noise level, thus meeting the requirements for cutting hair at different speeds.

[0056] The fan assembly 30 also includes a motor housing 34 and an adapter plate 35. The motor 31 includes a stator assembly 311 and a rotor assembly 312. The motor 31 and the fan blades 32 are disposed inside the motor housing 34, which protects the motor 31 and the fan blades 32, thereby extending their service life and ensuring their normal operation. The stator assembly 311 and the rotor assembly 312 work together to convert electrical energy into mechanical energy, and the fan blades 32 rotate. The adapter plate 35 is disposed at the end of the motor 31 away from the fan blades 32 and is connected to the third sub-housing 23, which allows the nursing device 100 to be bent at a certain angle, making it easier for the user to use the nursing device 100.

[0057] like Figure 1 , Figure 2 , Figures 6-8 As shown, the nursing device 100 according to the second aspect embodiment of the present invention includes: a shell 10, an inner shell 20, a fan assembly 30, a filter screen, and noise-reducing cotton 50. The inner shell 20 is disposed inside the shell 10 and forms an air duct 24. The fan assembly 30 is disposed inside the inner shell 20. The filter screen defines an air inlet area 212, which is located upstream of the air inlet 211. The noise-reducing cotton 50 is disposed at the bottom of the air inlet area 212 and has a gap between it and the filter screen.

[0058] It is understood that the outer shell 10, the inner shell 20, and the fan assembly 30 constitute the main structure of the nursing device 100. The outer shell 10 is fitted around the outer periphery of the inner shell 20, which protects the inner shell 20 and extends its service life. It also makes it easier for the user to hold the outer shell 10, thus facilitating the use of the nursing device 100. The inner shell 20 has a cavity inside, which forms an air duct 24, allowing airflow to pass through and restricting the direction of airflow. The fan assembly 30 is located inside the inner shell 20, which guides the airflow so that it blows towards the user.

[0059] The filter screen defines an air inlet area 212, which is located upstream of the air inlet 211. This allows airflow to pass through the filter screen and flow into the air duct 24. The noise-reducing cotton 50 is located at the bottom of the air inlet area 212, and the noise-reducing cotton 50 and the filter screen are spaced apart. This allows the noise-reducing cotton 50 to comb and reduce the noise of the airflow as it is about to enter the air inlet area 212, thereby maximizing the passage of airflow through the filter screen and reducing airflow noise. The two pieces of noise-reducing cotton 50 are arranged in parallel and spaced apart, so that the noise-reducing cotton 50 can comb and reduce the noise of airflow from different directions, thereby covering a wide range of airflow and improving the comfort of the nursing device 100.

[0060] Therefore, the inner shell 20 of the nursing device 100 is located inside the outer shell 10, and the inner side of the inner shell 20 forms an air duct 24. The fan assembly 30 is located in the inner shell 20, so that the airflow generated by the fan assembly 30 can be blown out through the air duct 24. Moreover, the filter screen limits the air intake area 212 in the air duct 24, so that the filter screen can filter impurities in the airflow, thereby ensuring the purity of the airflow blown out of the air duct 24. The air intake area 212 is located upstream of the air inlet 211, and the bottom of the air intake area 212 is provided with noise reduction cotton 50. The noise reduction cotton 50 is spaced apart from the filter screen, so that when the airflow enters the air duct 24, it is combed and noise-reduced by the noise reduction cotton 50, thereby further reducing the noise of the nursing device 100.

[0061] In addition, such as Figure 6As shown, the noise-reducing cotton 50 consists of two parallel pieces; a space is formed between the two pieces of noise-reducing cotton 50, within which electronic components are housed. In other words, the two pieces of noise-reducing cotton 50 are arranged parallel and spaced apart, allowing them to effectively manage and reduce noise from airflows in different directions, thus covering a wide range of airflow and improving the comfort of the nursing device 100. The space between the two pieces of noise-reducing cotton 50 allows the electronic components to be placed between them. The noise-reducing cotton 50 manages the airflow, preventing it from passing over the electronic components and protecting them from the effects of airflow.

[0062] like Figure 1 , Figure 2 , Figures 6-8 As shown, the nursing appliance 100 according to the third aspect embodiment of the present invention includes: a shell 10, an inner shell 20 and a fan assembly 30 disposed inside the shell 10, the inner shell 20 forming an air duct 24, and the fan assembly 30 disposed inside the inner shell 20; the fan assembly 30 includes a motor 31 and a fan blade 32, the fan blade 32 being rotatably connected to the motor 31 and driven by the motor 31 to rotate to generate airflow; the fan blade 32 includes a plurality of circumferentially distributed blades, and at least one blade having a circumferential edge forming a cutting edge 33 for cutting hair.

[0063] It is understood that the outer shell 10, the inner shell 20, and the fan assembly 30 constitute the main structure of the nursing device 100. The outer shell 10 is fitted around the outer periphery of the inner shell 20, which protects the inner shell 20 and extends its service life. It also makes it easier for the user to hold the outer shell 10, thus facilitating the use of the nursing device 100. The inner shell 20 has a cavity inside, which forms an air duct 24, allowing airflow to pass through and restricting the direction of airflow. The fan assembly 30 is located inside the inner shell 20, which guides the airflow so that it blows towards the user.

[0064] In this system, the power of the motor 31 is transmitted to the fan blade 32, which then rotates and generates airflow. The fan blade 32 consists of multiple blades that are circumferentially spaced. One end of each blade is connected to the motor 31, while the other end extends away from the motor 31, thus ensuring the flow of air. At least one blade has a chamfered edge on its circumferential edge, which allows it to cut foreign objects and impurities when rotating at high speed. This allows the blades to shred hair, which is then blown out through the air duct 24, preventing hair from getting tangled on the blades. This ensures the normal operation of the care device 100 and prevents the fan blade 32 from becoming blocked, thereby improving the lifespan of the care device 100 and the user experience.

[0065] Therefore, the inner shell 20 of the care appliance 100 is located inside the outer shell 10, and an air duct 24 is formed on the inner side of the inner shell 20. The fan assembly 30 is located in the inner shell 20, so that the airflow generated by the fan assembly 30 can be blown out through the air duct 24. The motor 31 in the fan assembly 30 drives the fan blade 32 to rotate. The fan blade 32 can generate airflow, and the blades in the fan blade 32 are constructed with a cutting edge 33 extending along the circumferential edge. The cutting edge 33 can cut the hair, which can prevent the hair from getting tangled in the fan assembly 30 and causing the fan assembly 30 to block. This can prevent the care appliance 100 from producing odors, dust and heat damage, and can also reduce the user's effort in cleaning and maintaining the care appliance 100, thereby improving the efficiency of the care appliance 100.

[0066] In particular, such as Figure 7 and Figure 8 As shown, the blade 33 extends radially from one end of the blade to the other, which ensures the length of the blade 33. Moreover, in the direction of rotation of the blade, the blade 33 is located at the front end of the direction of rotation of the blade. This ensures that when hair enters the care device 100, it contacts the blade 33 first, and the blade 33 cuts the hair. This avoids the care device 100 from generating odors, dust, and heat damage, and also reduces the effort required by the user to clean and maintain the care device 100, thereby improving the efficiency of the care device 100.

[0067] Furthermore, when the fan assembly is installed into the housing, the motor assembly can also be installed in an inverted manner. Specifically, the fan assembly can be located in the third sub-housing, and the vibration damping unit can be integrated into the third sub-housing. The fan assembly is positioned close to the main body, and the fan blades of the fan assembly are closer to the main body than the stator and rotor assemblies, such as... Figure 10 As shown. In this way, when the fan blades rotate and draw air, the airflow will first flow through the stator assembly and rotor assembly, which allows the heat-generating parts of the motor assembly to be fully dissipated.

[0068] According to a fourth aspect embodiment of the present invention, the nursing device 100 has a housing configured as a handle. A shock-absorbing portion 221 is provided on the inner wall of the inner shell 20 of the nursing device 100, allowing the shock-absorbing portion 221 and the inner shell 20 to be manufactured as a single unit, thereby reducing the complexity of the interior of the inner shell 20. Furthermore, the fan assembly 30 abuts against the shock-absorbing portion 221, which reduces the vibration of the fan assembly 30, thus reducing the vibration of the nursing device 100 and facilitating its assembly. The air inlet area is located upstream of the air inlet, and noise-reducing cotton 50 is provided at the bottom of the air inlet area. The noise-reducing cotton 50 is spaced apart from the filter screen, allowing airflow to pass through the noise-reducing cotton when entering the air duct 24. The 50% combing and noise reduction further reduces the noise of the care appliance 100. The motor 31 in the fan assembly 30 drives the fan blade 32 to rotate, and the fan blade 32 can generate airflow. Moreover, the blades in the fan blade 32 are constructed with a cutting edge 33 extending along the circumferential edge, which can cut the hair. This can prevent hair from getting tangled in the fan assembly 30 and causing the fan assembly 30 to block. This can prevent the care appliance 100 from producing odors, dust, and heat damage. It can also reduce the effort users put into cleaning and maintaining the care appliance 100, thereby improving the efficiency of the care appliance 100.

[0069] The hair care appliance 100 provided in the above embodiment also includes a main body 60 disposed above the handle. The main body is rotatable relative to the handle. In a first state, the length extension direction of the main body is parallel or aligned with the length extension direction of the handle; in a second state, the length extension direction of the main body is transverse to the length extension direction of the handle. Thus, the main body of the hair care appliance 100 can switch between a first state and a second state relative to the handle. In the first state, the length extension direction of the main body is parallel or aligned with the length extension direction of the handle, allowing for the use of styling accessories suitable for this structure, such as a curling iron, to style the hair and meet the user's needs. In the second state, the general layout of the hair care appliance 100 is similar to a traditional hair dryer, allowing the user to hold the hair care appliance 100 to dry their hair, or to use styling accessories suitable for this structure, such as a styling nozzle, to style their hair. This state switching allows the user's needs to be met.
