Description

Technical Field

[0001] This utility model relates to the field of nursing instrument technology, and in particular to a nursing comb. Background Technology

[0002] In existing technologies, the functional heads of scalp care devices are usually fixed to the handle and cannot be moved, and most of the functional heads are made of rigid materials. When the user uses the device, the comb teeth on the functional head come into direct contact with the user's scalp. However, since the user's head contour is not a regular plane, this structure results in poor flexibility of movement when using the scalp care device. At the same time, the pressure of the comb teeth on the head is uneven, resulting in poor fit between the scalp care device and the scalp. Utility Model Content

[0023] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-3 Description of a nursing comb 100 according to an embodiment of the present invention.

[0024] like Figures 1-3 As shown, the nursing comb 100 according to an embodiment of the present invention includes: a gripping part 10, a combing part 20, and a floating device 30.

[0025] Specifically, a first mounting hole 111 is formed on the grip portion 10, and at least one first limiting member 40 is provided in the first mounting hole 111. The comb portion 20 is provided in the longitudinal direction of the grip portion 10 (e.g., Figure 2 At one end of the comb portion 20 (in the left-right direction), a second mounting hole 21 is formed on the comb portion 20, and at least one second limiting member 50 is provided in the second mounting hole 21. The floating device 30 includes a floating component 31 and an elastic member 32. The two ends of the floating component 31 extend into the first mounting hole 111 and the second mounting hole 21, respectively, and the elastic member 32 is sleeved on the outer periphery of the floating component 31. The floating component 31 is movably disposed between the first limiting member 40 and the second limiting member 50, and part of the elastic member 32 is located between the grip portion 10 and the comb portion 20.

[0026] For example, in Figures 1-3 In the example, the grip portion 10 is generally an elongated arc-shaped structure, and the grip portion 10 includes a connecting segment 11 and a grip segment 12, in the thickness direction of the grip portion 10 (e.g., Figure 2 In the vertical direction, the maximum width of the gripping section 12 is greater than the maximum width of the connecting section 11. A first mounting hole 111 is provided on the connecting section 11. The first mounting hole 111 is a circular through hole 3113a, and the first mounting hole 111 extends along the thickness direction of the gripping part 10. The first mounting hole 111, the elastic element 32, and the second mounting hole 21 are coaxially arranged. In addition, the elastic element 32 is a hollow cylindrical structure. Both ends of the elastic element 32 have stepped portions in the axial direction. One stepped portion is fixed to the gripping part 10, and the other stepped portion is fixed to the comb part 20.

[0027] Furthermore, the comb portion 20 is located above the connecting section 11 of the grip portion 10. In the length direction of the grip portion 10, the length of the comb portion 20 is approximately half that of the grip portion 10, and in the width direction of the grip portion 10 (e.g., ...), Figure 1 In the left-right direction, the overall width of the comb part 20 is greater than the overall width of the grip part 10. The comb part 20 is generally a flat cuboid structure. The comb part 20 has a plurality of comb teeth 22 (8 in the figure, but not limited to this) on the arc-shaped surface away from the grip part 10 in the thickness direction. In the description of this utility model, "a plurality of" means two or more.

[0028] When in use, the user can hold the grip section 12 of the grip part 10. Since the grip part 10 has an overall arc-shaped structure, the direction of the grip part 10 is consistent with the shape of the user's hand when it is half-gripped, which improves the user's comfort. In addition, the grip part 10 and the comb part 20 are connected by a floating device 30. Since the floating component 31 is movably disposed between the first limiting member 40 and the second limiting member 50, when the comb part 20 contacts the scalp or hair and is subjected to external force, the comb part 20 transmits the external force to the elastic member 32 and the floating component 31. The floating component 31 can move between the first limiting member 40 and the second limiting member 50 and drive the comb part 20 to move, so that the comb part 20 can automatically adjust the angle according to the different contours of the head, fit the scalp of different areas and different curvatures (such as the top of the head and the back of the head), and the force is more even when combing, which further improves the user's comfort. Furthermore, the floating device 30 creates an "elastic connection" between the grip 10 and the comb 20, allowing the user's hand force to be naturally transmitted to the comb 20 through the floating component 31, making the user's operation more effortless.

[0029] In addition, at least one limiting member is provided in the mounting holes of the grip part 10 and the comb part 20 respectively, which limits the range of motion of the floating component 31, prevents the comb part 20 from shaking excessively or falling off, and ensures the working stability of the care comb 100. Moreover, when the comb part 20 is subjected to force and the floating component 31 moves between the first limiting member 40 and the second limiting member 50, the elastic member 32 generates elastic deformation, providing the user with clearer operation feedback, making it easier for the user to control the operation force more accurately; when the angle of the comb part 20 changes, the elastic member 32 can partially restore its elastic deformation, driving the floating component 31 to move flexibly between the first limiting member 40 and the second limiting member 50, making the angle change of the comb part 20 more flexible, that is, the comb part 20 can dynamically conform to the scalp, further improving the user's comfort; when the comb part 20 leaves the scalp or hair, the elastic member 32 restores its elastic deformation and drives the floating component 31 to reset, making it convenient for the user to use next time.

[0030] In summary, the nursing comb 100 according to this utility model embodiment, by setting a floating component 31 and an elastic member 32 between the grip part 10 and the comb part 20, and limiting the floating component 31 by the first limiting member 40 and the second limiting member 50, allows the comb part 20 to automatically adjust its angle according to the different contours of the head, improving the fit between the comb part 20 and the user's head, making the force more even during combing, enhancing the user's comfort, and making the user's operation more effortless, thus ensuring the working stability of the nursing comb 100.

[0031] According to some embodiments of the present invention, a plurality of grooves 321 are formed on the outer peripheral side of the elastic member 32. The plurality of grooves 321 are spaced apart along the axial direction of the elastic member 32, and each groove 321 extends along the circumferential direction of the elastic member 32.

[0032] For example, in Figure 3 In the example, there can be five grooves 321, but it is not limited to this. The five grooves 321 are along the axial direction of the elastic member 32 (e.g., Figure 3 The upper and lower directions of the elastic element 32 are spaced apart, so that the outer periphery of the elastic element 32 presents a sawtooth wave structure, which provides more space for the elastic deformation of the elastic element 32, makes the compression and extension of the elastic element 32 smoother, avoids stress concentration when the elastic element 32 undergoes elastic deformation, improves the working stability of the elastic element 32, and ensures the overall working reliability of the nursing comb 100.

[0033] According to some embodiments of this utility model, the hardness of the elastic element 32 is H, wherein H satisfies: 60≤H≤90.

[0034] When H < 60, the hardness of the elastic element 32 is too small, that is, the elastic element 32 is too soft and the elasticity of the elastic element 32 is poor. Since the elastic element 32 is located between the grip part 10 and the comb part 20, it plays a certain supporting role for the comb part 20. When the elastic element 32 is too soft, it cannot effectively support the comb part 20. When the user combs the hair, the comb part 20 is unable to resist the resistance of the hair and the pressure, which causes the comb part 20 to shake excessively or the user to be unable to accurately control the combing position and force, affecting the working stability and comfort of the hair care comb 100. Moreover, the elastic element 32 plays a supporting role for the comb part 20, which makes the elastic element 32 subject to long-term force. It is easy to have poor durability due to long-term deformation, which reduces the service life of the elastic element 32.

[0035] When H > 90, the hardness of the elastic element 32 is too high, that is, the elastic element 32 has poor elastic deformation ability. When the user uses it, the comb part 20 connected to the elastic element 32 has poor mobility and cannot flexibly adjust the angle and position of the comb part 20. The comb part 20 is prone to rigid contact with the scalp, causing the user to experience stinging or pressure, which reduces the user's experience.

[0036] Therefore, by setting the hardness H of the elastic element 32 between 60 and 90, the working stability and comfort of the care comb 100 are ensured, the service life of the elastic element 32 is extended, and the user experience is improved.

[0037] It should be noted that the elastic element 32 can be made of materials such as TPU (Thermoplastic Polyurethanes), and this application does not impose specific restrictions on it.

[0038] According to some embodiments of the present invention, the nursing comb 100 further includes: a first pressure plate 60 and a second pressure plate 70.

[0039] Specifically, the first pressure plate 60 is disposed within the first mounting hole 111 and abuts against the first limiting member 40. The second pressure plate 70 is disposed within the second mounting hole 21 and abuts against the second limiting member 50. The floating assembly 31 is movably disposed between the first pressure plate 60 and the second pressure plate 70, and the two axial ends of the elastic member 32 abut against the first pressure plate 60 and the second pressure plate 70, respectively.

[0040] Reference Figure 3 The first pressure plate 60 is located on the outer periphery of the first limiting member 40 and is coaxially arranged with the first limiting member 40. The side of the first pressure plate 60 near the center abuts against the first limiting member 40, and the side of the first pressure plate 60 near the edge abuts against the end of the elastic member 32 axially near the gripping portion 10. Similarly, the second pressure plate 70 is located on the outer periphery of the second limiting member 50 and is coaxially arranged with the second limiting member 50. The side of the second pressure plate 70 near the center abuts against the second limiting member 50, and the side of the second pressure plate 70 near the edge abuts against the end of the elastic member 32 axially near the comb portion 20.

[0041] In this configuration, the first pressure plate 60 supports and fixes the first limiting member 40, and the second pressure plate 70 supports and fixes the second limiting member 50. This ensures that the first limiting member 40 and the second limiting member 50 can reliably limit the floating component 31, preventing them from shifting or dislodging during use. Simultaneously, the first pressure plate 60 and the second pressure plate 70 can fix the elastic member 32 from both ends along its axial direction, preventing it from shifting or dislodging during compression and extension, further ensuring the mobility of the comb section 20. Furthermore, the first pressure plate 60 and the second pressure plate 70 improve the connectivity of the grip section 10, the floating component 31, the elastic member 32, and the comb section 20, enhancing the compactness and overall integrity of the nursing comb 100 structure.

[0042] It should be noted that the first pressure plate 60 and the first limiting member 40 can be integrally formed parts, and the second pressure plate 70 and the second limiting member 50 can be integrally formed parts. This application does not impose specific restrictions on this.

[0043] In some optional embodiments, one of the gripping part 10 and the first pressure plate 60 is provided with a plurality of first buckles 13, and the other of the gripping part 10 and the first pressure plate 60 is provided with a plurality of first slots (not shown in the figure), and each first buckle 13 engages with the corresponding first slot.

[0044] like Figure 3 As shown, the gripping part 10 is provided with six first buckles 13, and the outer periphery of the first pressure plate 60 is provided with six first slots spaced apart. The first buckles 13 engage with the first slots, which can fix the first pressure plate 60 axially and circumferentially, thereby firmly fixing the first pressure plate 60 and the elastic member 32 to the gripping part 10 at their axial ends near the gripping part 10, preventing the first pressure plate 60 and the elastic member 32 from loosening during use and ensuring the working stability of the care comb 100. Moreover, the structure of the first buckles 13 on the gripping part 10 can play a positioning role in the installation of the first pressure plate 60. The operator can install the first pressure plate 60 according to the position of the first buckles 13, improving the overall installation efficiency of the care comb 100. In addition, the engagement of the buckles and slots is relatively reliable, and the installation and disassembly are relatively simple, which facilitates the initial installation and subsequent maintenance of the care comb 100.

[0045] In some alternative embodiments, one of the comb portion 20 and the second pressure plate 70 is provided with a plurality of second buckles 23, and the other of the comb portion 20 and the second pressure plate 70 is provided with a plurality of second slots (not shown in the figure), and each second buckle 23 engages with the corresponding second slot.

[0046] like Figure 3 As shown, the comb section 20 is provided with six second buckles 23, and the outer periphery of the second pressure plate 70 is provided with six second slots at intervals. The second buckles 23 engage with the second slots, which can fix the second pressure plate 70 axially and circumferentially, thereby firmly fixing the second pressure plate 70 and the elastic element 32 to the holding part 10 at the end of the comb section 20 in the axial direction. This prevents the second pressure plate 70 and the elastic element 32 from loosening during use and ensures the working stability of the care comb 100. Moreover, the structure of the second buckles 23 on the comb section 20 can play a positioning role in the installation of the second pressure plate 70. The operator can install the second pressure plate 70 according to the position of the second buckles 23, which improves the overall installation efficiency of the care comb 100. In addition, the engagement of the buckles and slots is relatively reliable, and the installation and disassembly are relatively simple, which facilitates the initial installation and subsequent maintenance of the care comb 100.

[0047] According to some embodiments of the present invention, the floating component 31 includes a first floating member 311 and a second floating member 312. The first floating member 311 is movably sleeved on one end of the second floating member 312. One end of the second floating member 312 is located between the second pressure plate 70 and the first floating member 311. The other end of the second floating member 312 is adapted to abut against the first pressure plate 60.

[0048] like Figure 3As shown, the first floating member 311 is located at one end of the second floating member 312 in its axial direction near the comb portion 20, and the first floating member 311 is located on the outer periphery of the second floating member 312, which can limit the second floating member 312 from the radial direction. The second floating member 312 extends as a whole along the thickness direction of the grip portion 10.

[0049] With this configuration, the first pressure plate 60 restricts the maximum displacement of the second floating member 312 towards the gripping part 10, and the second pressure plate 70, in conjunction with the first floating member 311, restricts the maximum displacement of the second floating member 312 towards the comb part 20, thereby preventing the floating component 31 from coming out of the first mounting hole 111 or the second mounting hole 21. The first floating member 311 and the second floating member 312 are nested together, and the first floating member 311 has a radial constraint effect on the second floating member 312, avoiding excessive displacement of the second floating member 312 along its radial direction, ensuring that the adjustment of the angle and position of the comb part 20 is more reliable, thereby ensuring the working reliability of the care comb 100.

[0050] Specifically, the second floating member 312 includes a first connecting segment 3121 and a second connecting segment 3122 connected to each other. The outer diameter of the first connecting segment 3121 is larger than the outer diameter of the second connecting segment 3122. The first connecting segment 3121 is located between the second pressure plate 70 and the first floating member 311. The free end of the second connecting segment 3122 is adapted to abut against the first pressure plate 60.

[0051] Reference Figure 3 The second connecting section 3122 is generally a hollow cylindrical structure. The first connecting section 3121 is located at the end of the second connecting section 3122 facing the comb portion 20. The first connecting section 3121 is generally a "flared" structure, that is, along the direction from the grip portion 10 to the comb portion 20 (e.g., Figure 3 (In the vertical direction), the outer diameter of the first connecting segment 3121 gradually increases, and the smaller end of the first connecting segment 3121 is connected to the first connecting segment 3121. The larger end of the first connecting segment 3121 is located between the second pressure plate 70 and the first floating member 311.

[0052] When the floating component 31 is activated, the first connecting section 3121 can move between the second pressure plate 70 and the first floating member 311, and drive the entire floating component 31 to move along the length direction of the grip portion 10, thereby adjusting the angle and position of the comb portion 20; while the second connecting section 3122 can move along the thickness direction of the grip portion 10, thereby adjusting the distance between the comb portion 20 and the grip portion 10. Through the synergistic effect of the first connecting section 3121 and the second connecting section 3122, the angle of the comb portion 20 can be changed more flexibly, that is, the comb portion 20 can dynamically conform to the scalp, further improving the user's comfort.

[0053] In addition, the first connecting section 3121 of the second floating member 312 is located between the second pressure plate 70 and the first floating member 311, and the free end of the second connecting section 3122 is adapted to abut against the first pressure plate 60, which improves the connectivity between the floating component 31 and the gripping part 10 and the comb part 20, and enhances the compactness and integrity of the overall structure of the care comb 100.

[0054] According to some other embodiments of the present invention, a third mounting hole 71 is formed on the second pressure plate 70, and a limiting post 3123 is provided at one end of the first connecting section 3121 away from the second connecting section 3122. The limiting post 3123 is movably disposed in the third mounting hole 71.

[0055] like Figure 3 As shown, there can be four third mounting holes 71, and correspondingly, there can be four limiting posts 3123. The four limiting posts 3123 are spaced apart circumferentially along the first connecting section 3121. The third mounting hole 71 is a square hole, and the limiting posts 3123 extend axially along the first connecting section 3121. In the projection plane of the gripping part 10 in the thickness direction, the cross-sectional area of ​​the third mounting hole 71 is larger than the cross-sectional area of ​​the limiting post 3123, so that the third mounting hole 71 can limit the limiting post 3123 while ensuring that the limiting post 3123 can move freely within the third mounting hole 71.

[0056] The cooperation between the limiting post 3123 and the third mounting hole 71 allows the second floating member 312 to swing slightly, causing the comb section 20 to swing radially within a small range. This means the angle of the comb section 20 is adjustable, resulting in more even force distribution during hair combing and improved user comfort. Furthermore, when adjusting the angle of the comb section 20, the limiting post 3123 can move freely within the third mounting hole 71. When the limiting post 3123 abuts against the wall of the third mounting hole 71, it reaches the limit position of the comb section 20's angle adjustment, preventing excessive compression or stretching of the elastic member 32 and thus ensuring its failure and the reliability and lifespan of the care comb 100. In addition, during assembly, the limiting post 3123 can be inserted into the third mounting hole 71 to pre-position the floating component 31, improving the assembly efficiency of the care comb 100. In addition, by setting multiple limiting posts 3123 and a third mounting hole 71, the second floating component 312 is limited from multiple directions, avoiding stress concentration caused by local force and ensuring the working reliability of the floating component 31.

[0057] In some alternative embodiments, the first floating member 311 includes a third connecting segment 3111, a fourth connecting segment 3112, and a fifth connecting segment 3113, wherein the fourth connecting segment 3112 is along the thickness direction of the gripping portion 10 (e.g., Figure 3Extending vertically, the third connecting segment 3111 and the fifth connecting segment 3113 are respectively connected to the two ends of the fourth connecting segment 3112 in the thickness direction of the gripping portion 10, and the third connecting segment 3111 and the fifth connecting segment 3113 extend in a direction away from the fourth connecting segment 3112. Among them, the third connecting segment 3111 is located between the elastic member 32 and the second pressure plate 70, and the first connecting segment 3121 is located between the fifth connecting segment 3113 and the second pressure plate 70.

[0058] For example, in Figure 3 In the example, the third connecting segment 3111 and the fourth connecting segment 3112 form a stepped structure and abut against the elastic member 32. The fifth connecting segment 3113 extends downward along the thickness direction of the gripping part 10. The fifth connecting segment 3113 has a through hole 3113a for the second connecting segment 3122 to pass through. The diameter of the through hole 3113a is larger than the outer diameter of the second connecting segment 3122. The fifth connecting segment 3113 and the second pressure plate 70 or the second limiting member 50 together define the floating channel 3113b. The first connecting segment 3121 is located in the floating channel 3113b.

[0059] The arrangement of the third connecting section 3111 and the fourth connecting section 3112 allows the first floating member 311 to be firmly fixed between the elastic member 32 and the second pressure plate 70, and provides support for the fifth connecting section 3113, ensuring the structural stability of the first floating member 311. This allows the first connecting section 3121 of the second floating member 312 to float stably between the fifth connecting section 3113 and the second pressure plate 70, ensuring the stability of the angle and position adjustment of the comb section 20 and further improving the user's comfort.

[0060] In addition, the diameter of the through hole 3113a on the fifth connecting section 3113 is larger than the outer diameter of the second connecting section 3122, so that the second floating member 312 can be displaced in its radial direction, thereby facilitating the adjustment of the angle and position of the comb section 20 and further improving the user's comfort.

[0061] According to some embodiments of the present invention, a first limiting portion 72 is provided on one side of the second pressure plate 70 adjacent to the first connecting section 3121. The first limiting portion 72 extends in the direction toward the first pressure plate 60, and in the length direction of the gripping portion 10 (e.g., Figure 3 The fourth connecting segment 3112 (in the left-right direction) is located between the elastic member 32 and the first limiting part 72.

[0062] The first limiting part 72 and the second limiting member 50 are configured to restrict the movement of the limiting post 3123 in the length direction of the gripping part 10, thereby limiting the angle adjustment range of the comb part 20 in the horizontal direction. This prevents the elastic member 32 from being excessively twisted, which could lead to localized stress or stress concentration, and ensures the operational reliability of the floating device 30. Simultaneously, when the first connecting section 3121 moves to its limit position along the thickness direction of the gripping part 10, the limiting post 3123 at the end of the first connecting section 3121 abuts against the first limiting part 72, and does not directly contact the fourth connecting section 3112 of the first floating member 311. This prevents the fourth connecting section 3112 from being directly stressed, which could cause the connection between the first floating member 311 and the elastic member 32 or the second pressure plate 70 to loosen, further ensuring the operational reliability of the floating device 30.

[0063] According to some embodiments of the present invention, a fourth mounting hole 61 is formed on the first pressure plate 60, a second limiting part 62 is provided on the inner side wall of the fourth mounting hole 61, a third limiting part 3124 is provided on the free end of the second connecting section 3122, the free end of the second connecting section 3122 extends into the fourth mounting hole 61, and the third limiting part 3124 is adapted to abut against the second limiting part 62.

[0064] Specifically, such as Figure 3 As shown, the second limiting part 62 includes two opposing second limiting blocks 621, the minimum distance between the two second limiting blocks 621 is greater than the outer diameter of the second connecting section 3122, and the third limiting part 3124 includes two opposing third limiting blocks 3124a, each of which is adapted to abut against the corresponding second limiting block 621, the maximum distance between the two third limiting blocks 3124a is greater than the minimum distance between the two second limiting blocks 621. When the surface of the third limiting block 3124a facing the comb part 20 is in contact with the surface of the second limiting block 621 facing the grip part 10, the second floating member 312 moves to the first limit position in its axial direction, thereby limiting the maximum displacement of the second floating member 312 in the direction of the comb part 20, preventing the second floating member 312 from falling out of the fourth mounting hole 61 and causing the floating component 31 to fail, thereby ensuring the working reliability of the care comb 100. At the same time, when the third limiting part 3124 and the second limiting part 62 approach each other, the elastic member 32 is in a state of restoring deformation or stretching. Through the cooperation of the third limiting part 3124 and the second limiting part 62, the elastic member 32 is prevented from being overstretched and causing elastic failure, which further ensures the working reliability of the nursing comb 100.

[0065] In addition, in some optional embodiments, a fourth limiting portion 3125 is provided on the axial sidewall of the second connecting segment 3122. The fourth limiting portion 3125 is disposed adjacent to the first connecting segment 3121 and is adapted to abut against the second limiting portion 62.

[0066] Specifically, such as Figure 3 As shown, the outer diameter of the fourth limiting part 3125 is greater than the minimum distance between the two second limiting blocks 621. When the elastic member 32 is compressed and the second connecting section 3122 moves along the comb part 20 toward the holding part 10, the fourth limiting part 3125 gradually approaches the second limiting part 62. When the surface of the fourth limiting part 3125 facing the holding part 10 is in contact with the surface of the second limiting block 621 facing the comb part 20, the second floating member 312 moves to the second limit position in its axial direction, thereby limiting the maximum displacement of the second floating member 312 toward the holding part 10. Since the elastic member 32 is in a compressed state during this process, the cooperation between the fourth limiting part 3125 and the second limiting part 62 prevents the elastic member 32 from being over-compressed and causing elastic failure, further ensuring the working reliability of the care comb 100.

[0067] Specifically, a wire passage 3122a is provided on the second connecting section 3122. The wire passage 3122a is connected to the fourth mounting hole 61, which facilitates the passage of cables in the comb part 20 and the grip part 10, and reduces the overall weight of the second floating member 312, which is conducive to the lightweight design of the care comb 100.
