Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a nursing device. Background Technology

[0002] Hair dryers and other hair care tools are everyday hair styling tools whose core function is to quickly dry hair and assist in styling, especially through the included nozzle attachments to achieve a smoother hairstyle.

[0003] Traditional nozzle attachments are usually only magnetically attached to the air outlet of the hair care device. When the nozzle attachment is a wide-tooth comb, the comb teeth come into contact with the hair when styling the hair, and the nozzle attachment is usually subjected to vertical shearing force. However, traditional magnetic nozzle attachments can only provide horizontal suction force. When the hair is too frizzy or the shearing force on the nozzle attachment is too great, the nozzle attachment is easy to fall off the hair care device.

[0004] Therefore, it is necessary to improve existing nursing equipment to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a nursing device that can effectively prevent the nozzle attachment from falling off the nursing body.

[0006] To achieve the above objectives, this utility model provides a nursing device comprising a nursing body and a nozzle attachment detachably connected to the nursing body. The nozzle attachment has an installation end and an air outlet end arranged opposite to each other. The nozzle attachment has a plurality of comb teeth at its air outlet end and a first connecting part at its installation end. One of the nozzle attachment and the nursing body has a second connecting part, and the other has an insertion groove that mates with the second connecting part. The nozzle attachment and the nursing body are detachably connected through the first connecting part and the second connecting part. A bonding force is formed between the first connecting part and the nursing body in a first direction, which is parallel to the extension direction of the comb teeth. The second connecting part is inserted into the insertion groove and can form a bonding force between the nozzle attachment and the nursing body in a second direction, which is angled to the extension direction of the comb teeth.

[0007] Thus, the first connecting part connects to the care unit, forming a bonding force in the first direction, thereby creating a primary connection between the nozzle attachment and the care unit, preventing the nozzle attachment from being pulled off by hair. Through the cooperation of the second connecting part and the insertion slot, a secondary connection is formed between the nozzle attachment and the care unit, preventing the nozzle attachment from deflecting and falling off during use. This dual connection method of the first and second connecting parts enhances the stability of the nozzle attachment, preventing it from falling off the care unit during use. Especially when combing hair, users may apply force in different directions, and the comb teeth will be subjected to shearing forces in various directions. The dual connection of the first and second connecting parts achieves connections in different directions, preventing the nozzle attachment from being broken by shearing forces in a different direction, thus reducing the risk of the nozzle attachment loosening or falling off, minimizing damage to the nozzle attachment and hair caused by accidental detachment, and ensuring the stability of the connection between the nozzle attachment and the care unit.

[0008] As a further improvement of this utility model, the first connecting part attracts the nursing body to form a bonding force in the first direction.

[0009] Thus, the nozzle attachment and the nursing body are joined in the first direction by the magnetic attraction between the first connecting part and the nursing body, making it easier to assemble and disassemble the nozzle attachment and the nursing body.

[0010] As a further improvement of this utility model, the second connecting part is constrained by the insertion groove to form a bonding force in the second direction.

[0011] Thus, the connection in another direction is achieved through the restriction between the second connecting part and the nursing body, preventing the connection in the first direction from being broken and falling off.

[0012] As a further improvement of this utility model, the nursing body is provided with a plug groove that is open to its air outlet side, and the air nozzle accessory is provided with a second connecting part. The second connecting part has a plug wall that protrudes in the direction away from the comb teeth and is inserted into and confined in the plug groove.

[0013] Thus, the radial direction limiting and stopping are achieved by the interlocking wall formed by the protrusion on the second connecting part and the interlocking groove on the nursing body.

[0014] As a further improvement of this utility model, the second connecting part has a snap-fit ​​part protruding on the insertion wall, and the nursing body has a mating part located in the insertion groove to snap with the snap-fit ​​part.

[0015] In this way, the snap-fit ​​portion formed by the protrusion on the plug-in wall achieves the snap-fit ​​with the plug-in groove, which not only enhances the bonding force in the first direction, but also forms a restriction in other directions different from the first direction, thereby effectively preventing the second connecting part from detaching from the plug-in groove under improper external force.

[0016] As a further improvement of this utility model, the second connecting part has at least two snap-fit ​​parts spaced apart in the circumferential direction, and the snap-fit ​​parts are symmetrically distributed with respect to the central axis of the nozzle accessory or evenly distributed along the circumferential direction of the nozzle accessory.

[0017] In this way, by using at least two snap-fit ​​parts arranged in the circumferential direction, a balanced connection in the circumferential direction is achieved, effectively resisting shear forces in all directions.

[0018] As a further improvement of this utility model, the snap-fit ​​part is protruding from the periphery of the plug-in wall. The snap-fit ​​part has a guide surface provided at the air outlet end away from the nozzle accessory and a locking surface provided at the air outlet end close to the nozzle accessory. The slope of the guide surface is less than the slope of the locking surface.

[0019] Thus, when installing the nozzle accessory into the nursing unit, the guide surface first enters the insertion slot of the nursing unit. The guide surface with a smaller slope reduces the installation resistance, allowing the locking part to pass over the mating part more smoothly until the locking surface locks with the mating part. The locking surface with a larger slope increases the resistance when the nozzle accessory is pulled out, thereby increasing the difficulty of the nozzle accessory falling off under improper external force, thus achieving smooth installation and a stable connection.

[0020] As a further improvement of this utility model, the nozzle accessory also has a wind cover with an internal air outlet channel, and the comb teeth and the wind cover are integrally formed.

[0021] In this way, by molding the comb teeth and the fan cover into one piece, the strength of the comb teeth is enhanced, and damage caused by bumps is avoided. At the same time, the process of installing the comb teeth is eliminated, simplifying the assembly steps during manufacturing.

[0022] As a further improvement of this utility model, the cross-section of the first end of the wind shield in the radial direction is circular, and the cross-section of the second end in the radial direction is duckbill-shaped, and the wind shield smoothly transitions from the first end to the second end.

[0023] Thus, the wind shield, which is integrated with the comb teeth, is designed to change from a circle to a duckbill shape, making the airflow to the air outlet more concentrated, thereby increasing the airflow speed, while making the airflow more stable and reducing turbulence.

[0024] As a further improvement of this utility model, the comb teeth extend from the second end in a direction away from the first end, and a number of comb teeth are arranged along the length direction of the second end. Each comb tooth connects the two sides of the wind hood that are opposite to each other, so as to span the air outlet port of the wind hood.

[0025] In this way, the comb teeth connect the two opposite sides of the wind hood to span the air outlet of the wind hood, thereby dispersing the airflow more evenly and making the airflow between adjacent comb teeth more uniform and gentle.

[0026] As a further improvement of this utility model, the nozzle accessory includes a housing with an air outlet channel formed inside, comb teeth connected to the air outlet end of the housing, and a plurality of comb teeth including a pair of side teeth located on the outermost side in its arrangement direction, the pair of side teeth being arranged opposite to each other on both sides in the arrangement direction, and the outer side of the side teeth in the arrangement direction of the comb teeth being seamlessly connected to the housing.

[0027] In this way, by seamlessly connecting the outer surface of the edge teeth to the shell, the noise of the airflow passing through the comb teeth is reduced, the abruptly changing arc surfaces on both sides of the shell are blocked, and the turbulence of the airflow is reduced, thus improving the stability of the airflow.

[0028] As a further improvement of this utility model, the nozzle accessory also includes a guide member housed within the housing, and a second connecting portion is formed on the guide member and protrudes from the side where the housing is connected to the nursing body.

[0029] In this way, by forming a second connection on the guide, the shape of the housing and the shape of the care unit are avoided.

[0030] The beneficial effects of this utility model are as follows: The nursing device of this utility model forms a bonding force in the first direction by connecting the first connecting part to the nursing body, thereby forming a primary connection between the nozzle attachment and the nursing body, preventing the nozzle attachment from being pulled off by hair; through the cooperation of the second connecting part and the insertion slot, a secondary connection is formed between the nozzle attachment and the nursing body, thereby preventing the nozzle attachment from deflecting and falling off during use; thus, the dual connection method of the first and second connecting parts can enhance the stability of the nozzle attachment, preventing it from falling off from the nursing body during use, especially when combing hair, users may apply forces in different directions, and the comb teeth will be subjected to shearing forces in various directions. The dual connection of the first and second connecting parts realizes the connection in different directions, avoiding the nozzle attachment from being broken off by shearing forces in a different direction in the first direction, thereby reducing the risk of the nozzle attachment loosening or falling off, reducing the damage to the nozzle attachment and hair caused by accidental detachment, and ensuring the stability of the connection between the nozzle attachment and the nursing body.

[0045] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0046] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0047] Figures 1 to 9 The present invention illustrates one embodiment of the nursing device 100. In this invention, the nursing device 100 includes a nursing body 1 and a nozzle accessory 2 detachably connected to the nursing body 1.

[0048] The nozzle accessory 2 has an installation end 201 and an air outlet end 202 that are arranged opposite to each other. The nozzle accessory 2 has a plurality of comb teeth 21 at its air outlet end 202. The plurality of comb teeth 21 includes a pair of side teeth 212 located on the outermost side in its arrangement direction. The pair of side teeth 212 are arranged opposite to each other on both sides in the arrangement direction of the comb teeth 21.

[0049] The extension direction of the comb teeth 21 is parallel to the direction from the mounting end 201 to the air outlet end 202, that is, the extension direction of the comb teeth 21 is consistent with the air outlet direction of the nursing body 1. In this embodiment, the extension direction of the comb teeth 21 is perpendicular to the arrangement direction of the comb teeth 21.

[0050] The nozzle attachment 2 has a first connecting part 203 at its mounting end. The first connecting part 203 and the nursing body 1 form a bonding force in a first direction, which is parallel to the extension direction of the comb teeth 21.

[0051] One of the nozzle attachment 2 and the nursing unit 1 is provided with a second connecting part 3, and the other is provided with a plug groove 4 that mates with the second connecting part 3. The nozzle attachment 2 and the nursing unit 1 are detachably connected via the first connecting part 203 and the second connecting part 3.

[0052] The second connecting part 3 is inserted into the insertion slot 4 and can form a bonding force in a second direction between the nozzle accessory 2 and the nursing body 1. The second direction is set at an angle to the extension direction of the comb teeth 21. That is, the second direction is not parallel to the first direction. It can be a direction orthogonal to the extension direction of the comb teeth 21 or a direction oblique to the extension direction of the comb teeth 21.

[0053] The first connecting part 203 connects to the care unit 1, forming a bonding force in the first direction, thus forming a primary connection between the nozzle attachment 2 and the care unit 1, preventing the nozzle attachment 2 from being pulled off by hair. The second connecting part 3 and the insertion slot 4 cooperate to form a secondary connection between the nozzle attachment 2 and the care unit 1, preventing the nozzle attachment 2 from deflecting and falling off during use. This dual connection method of the first connecting part 203 and the second connecting part 3 enhances the stability of the nozzle attachment 2, preventing it from falling off the care unit 1 during use. Especially when combing hair, users may apply force in different directions, and the comb teeth 21 will be subjected to shearing forces in various directions. The dual connection of the first connecting part 203 and the second connecting part 3 achieves connections in different directions, preventing the nozzle attachment 2 from being broken by shearing forces different from the first direction, thus reducing the risk of the nozzle attachment 2 loosening or falling off, reducing damage to the nozzle attachment 2 and hair caused by accidental detachment, and ensuring the stability of the connection between the nozzle attachment 2 and the care unit 1.

[0054] Specifically, in one embodiment, the first connecting portion 203 attracts the nursing body 1 to form a bonding force in a first direction. In this embodiment, the first connecting portion 203 is a magnetic component that can be attracted to the magnetism of the nursing body 1; specifically, the first connecting portion 203 can be a one-piece ring-shaped magnetic component or a ring structure formed by several magnetic components arranged at intervals. In other embodiments, a magnetic component can also be provided at the end of the nursing body 1 that is connected to the nozzle accessory 2, and the first connecting portion 203 is a component that can be connected to the magnetic component.

[0055] Thus, the nozzle attachment 2 and the nursing body 1 are joined in the first direction by the magnetic attraction between the first connecting part 203 and the nursing body 1, making it easier to assemble and disassemble the nozzle attachment 2 and the nursing body 1.

[0056] The second connecting part 3 is constrained by the insertion groove 4 to form a bonding force in the second direction. Specifically, the second connecting part 3 can be configured to be directly or indirectly snapped into the insertion groove 4, or the outer diameter of the second connecting part 3 can be set to be slightly larger than the outer diameter of the insertion groove 4 so as to be directly inserted into the insertion groove 4, or it can be configured to be inserted into the insertion groove 4 by means of a threaded connection.

[0057] Thus, the connection in another direction is achieved by the restriction between the second connecting part 3 and the nursing body 1, preventing the connection in the first direction from being broken and falling off.

[0058] Furthermore, such as Figure 9As shown, in this embodiment, the second connecting part 3 is disposed on the nozzle accessory 2, and the insertion groove 4 is disposed on the nursing body 1, with the insertion groove 4 open towards the air outlet side of the nursing body 1. The second connecting part 3 has an insertion wall 31 protruding in a direction away from the comb teeth 21, and the insertion wall 31 is inserted into and confined within the insertion groove 4.

[0059] Thus, the radial direction limiting and stopping are achieved by the cooperation between the insertion wall 31 protruding on the second connecting part 3 and the insertion groove 4 on the nursing body 1.

[0060] In other embodiments of this utility model, the positions of the insertion slot 4 and the second connecting part 3 can also be the same as those of the other two parts. Figure 9 In the embodiment shown, the positions are reversed, that is, the insertion slot 4 is provided on the nozzle attachment 2 and is located on the side where the nozzle attachment 2 is connected to the nursing body 1. At this time, the second connecting part 3 is provided on the nursing body 1.

[0061] In this embodiment, the second connecting part 3 is provided with a stepped surface 32 adjacent to the insertion wall 31, so that the outer diameter of the insertion wall 31 is smaller than that of the part of the second connecting part 3 adjacent to it, thereby reducing the radial dimension of the insertion wall 31, thereby reducing the radial dimension of the nursing body 1, which is conducive to the miniaturization of the nursing device 100.

[0062] In other embodiments, the insertion wall 31 may also be formed directly and smoothly on the side of the second connection portion 3 away from the air outlet end 202.

[0063] like Figure 2 , Figures 8 to 9 As shown, the second connecting part 3 has a snap-fit ​​part 34 protruding from the insertion wall 31, and the nursing body 1 has a mating part 12 located in the insertion groove 4 to engage with the snap-fit ​​part 34. In this way, the snap-fit ​​part 34 protruding from the insertion wall 31 achieves the engagement with the insertion groove 4, which not only enhances the bonding force in the first direction, but also forms a restriction in other directions different from the first direction, thereby effectively preventing the second connecting part 3 from disengaging from the insertion groove 4 under improper external force.

[0064] In this embodiment, as Figure 8 As shown, the mating part 12 is a protruding strip formed in the insertion groove 4 and has a continuous annular structure, so that the snap-fit ​​part 34 of the nozzle attachment 2 can be inserted in any direction and can be snapped with the mating part 12 of the nursing body 1; in other embodiments, the mating part 12 may also be a discontinuously arranged protruding structure, so that after the nozzle attachment 2 is inserted into the nursing body 1 in a preset direction, it can be snapped with the snap-fit ​​part 34 after rotation.

[0065] The second connecting part 3 has at least two locking parts 34 spaced apart in the circumferential direction. The locking parts 34 are symmetrically distributed with respect to the central axis of the nozzle attachment 2 or evenly distributed along the circumferential direction of the nozzle attachment 2.

[0066] When there are two locking parts 34, the two locking parts 34 are symmetrically distributed with respect to the central axis of the nozzle attachment 2; when there are three or more locking parts 34, the locking parts 34 are evenly distributed along the circumferential direction of the nozzle attachment 2. In this way, by arranging at least two locking parts 34 in the circumferential direction, a balanced connection in the circumferential direction is achieved, effectively resisting shear forces in all directions.

[0067] Specifically, refer to Figure 3 and Figure 6 As shown, the snap-fit ​​portion 34 protrudes from the periphery of the insertion wall 31. The snap-fit ​​portion 34 has a guide surface 341 located away from the air outlet end 202 of the nozzle attachment 2 and a locking surface 342 located near the air outlet end 202 of the nozzle attachment 2. The slope of the guide surface 341 is less than the slope of the locking surface 342. That is, compared to the inclination of the guide surface 341, the inclination of the locking surface 342 is steeper. In other words, the acute angle formed by the intersection of the guide surface 341 and the central axis of the nursing body 1 is less than the acute angle formed by the intersection of the locking surface 342 and the central axis.

[0068] Thus, when the nozzle accessory 2 is installed into the nursing unit 1, the guide surface 341 first enters the insertion slot 4 of the nursing unit 1. The installation resistance is reduced by the guide surface 341 with a smaller slope, so that the snap-fit ​​part 34 can pass over the mating part 12 more smoothly until the locking surface 342 is engaged with the mating part 12. The resistance when the nozzle accessory 2 is pulled out is increased by the locking surface 342 with a larger slope, thereby increasing the difficulty of the nozzle accessory 2 falling off under improper external force, thus achieving smooth installation and stable connection.

[0069] In this embodiment, the insertion wall 31 is annular, and the snap-fit ​​portion 34 is distributed on the outer peripheral surface of the insertion wall 31; in other embodiments, the insertion wall 31 may also be configured as two or more spaced apart from each other in the circumferential direction, and at least one snap-fit ​​portion 34 is protruding on each insertion wall 31.

[0070] Please refer to Figure 7 and Figure 9 As shown, in this embodiment, the nozzle accessory 2 also includes a housing 23 and a guide member 24. An air outlet channel 230 is formed inside the housing 23, and the guide member 24 is housed inside the housing 23.

[0071] Specifically, in one embodiment, the housing 23 includes a fan shroud 231 and an outer shell 232, making it a double-layer structure. This double-layer structure can block heat conduction and create an air gap between the fan shroud 231 and the outer shell 232, further reducing the temperature of the outer surface of the nozzle accessory 2 to achieve the effect of preventing scalding. An air outlet channel 230 is formed inside the fan shroud 231. In other embodiments, the housing 23 may also have only the fan shroud 231, that is, it is a single-layer structure.

[0072] In this embodiment, the comb teeth 21 and the fan cover 231 are integrally formed. That is, the comb teeth 21 extend integrally from the fan cover 231. In this way, by integrally forming the comb teeth 21 and the fan cover 231, the robustness of the comb teeth 21 is enhanced, and damage caused by bumps is avoided. At the same time, the process of installing the comb teeth is eliminated, simplifying the assembly steps during manufacturing.

[0073] The first end of the blower 231 has a circular cross-section in the radial direction, and the second end has a duckbill-shaped cross-section in the radial direction. The blower 231 smoothly transitions from the first end to the second end. The second end of the blower 231 is duckbill-shaped, and its length dimension is larger than its height dimension. The length direction of the second end is perpendicular to the extension direction of the comb teeth 21. Setting the length dimension of the second end of the blower 231 to be larger increases the contact area between the second end and the hair, shortening the drying time; at the same time, it can also be adapted to the comb teeth 21 to achieve hair styling and care, reducing damage to the hair from turbulence.

[0074] Thus, the wind shield 231, which is integrated with the comb teeth 21, is designed to change from a circle to a duckbill shape, so that the airflow flowing to the air outlet is more concentrated, thereby increasing the airflow speed and making the airflow more stable and reducing turbulence.

[0075] In this embodiment, the comb teeth 21 extend from the second end toward a direction away from the first end, and a plurality of comb teeth 21 are arranged along the length direction of the second end. Each comb tooth 21 connects the two opposite sides of the wind hood 231 to span the air outlet port of the wind hood 231.

[0076] In this way, the comb teeth 21 connect the two opposite sides of the wind shield 231 to span the air outlet of the wind shield 231, thereby dispersing the airflow more evenly and making the wind force between adjacent comb teeth 21 more uniform and gentle.

[0077] In one embodiment, an air outlet channel is formed inside the housing 23, the comb teeth 21 are connected to the air outlet end of the housing 23, and the outer side of the side teeth 212 in the arrangement direction of the comb teeth 21 is seamlessly connected to the housing 23.

[0078] In this way, by seamlessly connecting the outer surface of the edge teeth 121 to the housing 23, the noise of the airflow passing through the comb teeth 21 is reduced, the abruptly changing arc surfaces on both sides of the housing 23 are blocked, the turbulence of the airflow is reduced, and the stability of the airflow is improved.

[0079] In the illustrated embodiment, an air outlet channel is formed within the shroud 231, and the outer surface of the side teeth 212 in the direction of the arrangement of the comb teeth 21 is seamlessly connected to the shroud 231.

[0080] Please refer to Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, the second connecting portion 3 is formed on the flow guide 24 and protrudes from the side where the housing 23 connects to the nursing body 1. Thus, by forming the second connecting portion 3 on the flow guide 24, the shape of the housing 23 and the nursing body 1 are not affected. In other embodiments, the second connecting portion 3 may also be formed directly on the housing 23.

[0081] The guide member 24 is also provided with a receiving groove 241 for receiving the first connecting part 203. The first connecting part 203 is reliably fixed by the receiving groove 241 to prevent it from falling off the guide member 24.

[0082] In summary, the nursing device 100 of this utility model is connected to the nursing body 1 through the first connecting part 203, forming a bonding force in the first direction, thereby forming a primary connection between the nozzle attachment 2 and the nursing body 1, preventing the nozzle attachment 2 from being pulled off by hair; through the cooperation of the second connecting part 3 and the insertion slot 4, a secondary connection is formed between the nozzle attachment 2 and the nursing body 1, thereby preventing the nozzle attachment 2 from deflecting and falling off during use; thus, the dual connection method of the first connecting part 203 and the second connecting part 3 can enhance the stability of the nozzle attachment 2 and prevent it from falling off during use. During the process, the nozzle attachment 2 will detach from the care unit 1. Especially when combing hair, the user may apply force in different directions, and the comb teeth 21 will be subjected to shearing forces in various directions. The connection in different directions is achieved through the double connection of the first connecting part 203 and the second connecting part 3. This avoids the nozzle attachment 2 from being broken by shearing forces in different directions when it is connected to the care unit 1 in the first direction, thereby reducing the risk of the nozzle attachment 2 loosening or falling off, reducing the damage to the nozzle attachment and the damage to the hair caused by accidental detachment, and ensuring the stability of the connection between the nozzle attachment 2 and the care unit 1.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
