Description

TECHNICAL FIELD

[0001] The present application relates to the field of hair grooming tools, in particular to a reciprocating comb assembly for grooming pet hair and an electric hair comb having the same. BACKGROUND

[0002] At present, with the improvement of living standards, pet keeping has become a favorite that occupies a large proportion of time in life. The most common pet keeping annoyance is the shedding and scattering of pet hair. In order to reduce the collection and processing work of scattered hair, some pet owners use a special pet comb to groom their pets, which can collect the hair in advance and reduce the scattering of hair on the pet.

[0003] At present, pet owners use various types of hair combs to adapt to different animals, different seasons, and different breeds. However, most hair grooming is done manually in front of and behind the pet, and there is a lack of electric hair grooming tools that can reduce the labor intensity of pet owners and simulate manual grooming or even have a massage effect.

[0004] In addition, there are some hair combing products on the market that can use negative pressure to suck the hair combed out, which can prevent hair from flying and make it convenient for users. However, such products also have some inconveniences, that is, the hair combed out from the pet will be stuck on the comb teeth, and the user needs to manually push the separation plate repeatedly to separate the hair from the comb teeth, which is not convenient and the separation effect is not good. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a reciprocating comb assembly and an electric hair comb having the same, which can realize reciprocating combing of hair under electric drive and reduce the labor intensity of manual combing.

[0006] In a first aspect, the present application provides a reciprocating comb assembly, comprising: a comb tooth unit and a reciprocating drive unit; The comb tooth unit comprises a comb plate and a plurality of comb teeth, and the comb teeth are fixed on the comb plate. The reciprocating drive unit is in transmission connection with the comb plate and is used to drive the comb tooth unit to make reciprocating motion along a predetermined combing track. The beneficial effect of this is that the comb tooth unit makes reciprocating motion under the drive of the reciprocating drive unit, which can replace manual reciprocating pushing and pulling of the comb tooth unit and reduce the labor intensity of the person. In addition, the reciprocating motion has a smaller amplitude and a higher frequency than manual combing, which makes it easier to make the hair fluffy and natural.

[0007] To further optimize this technical solution, the number of comb tooth units is increased to two, and the reciprocating motions of the two comb tooth units are set in opposite phases. The beneficial effect of this is that when the two comb tooth units comb the hair together, the two reaction forces on the working surface cancel each other out when the motion phases are opposite, which can reduce the overall sway of the pet and the reciprocating comb assembly, and also help the operator to use it smoothly.

[0008] To further optimize this technical solution, the reciprocating drive unit includes a drive motor, a support frame, and eccentric shafts in the same number as the comb units. The drive motor is mounted on the support frame. The power output shaft of the drive motor is coupled to each comb unit via an eccentric shaft. The eccentric shaft is eccentrically connected to the power output shaft. The eccentric shaft is concentrically rotatably connected to the corresponding comb plate. When there are two comb units, the eccentric shafts corresponding to the two comb units are distributed vertically and horizontally in the axial direction of the power output shaft and are set in opposite phases. A limiting pair is provided between each comb plate and the support frame, and the limiting pair is used to guide the reciprocating motion of the comb unit. The advantages of this are: simple and reliable structure; the motion plane of the comb unit is defined by the power output shaft, and the trajectory of the reciprocating motion of the comb unit in the motion plane is defined by the limiting pair. By setting the eccentricity of the eccentric shaft, the reciprocating motion amplitude of the comb unit towards the center of the power output shaft can be preset; by setting the line shape of the limiting pair, the angle of the comb unit's own reciprocating swing can be preset. This comprehensive setting allows for the free and flexible creation of reciprocating motion trajectories adapted to different application scenarios.

[0009] As an embodiment of the above solution, both limiting pairs are linear and symmetrically distributed along the diameter direction of the power output shaft. This has the advantage of minimizing the oscillation angle of the comb unit, thus reducing energy consumption.

[0010] As an embodiment of the above solution, both limiting pairs are S-shaped and symmetrically distributed along the diameter direction of the power output shaft. The beneficial effect of this is that the comb unit reciprocates in the combing direction, increasing the frictional force of the combing and improving the efficiency of removing loose hair.

[0011] As one embodiment of the above solution, the comb plate includes a base plate and a connecting plate, the comb teeth are fixed on the connecting plate, and the connecting plate is detachably connected to the base plate. This allows the invention to use comb teeth of different lengths, thicknesses, curvatures, and densities, improving adaptability to different application scenarios.

[0012] As an embodiment of the above solution, a cleaning mechanism is also included. This cleaning mechanism comprises a support base and cleaning bristles circumferentially distributed on the support base. The support base is linked to a power output shaft, and the rotational trajectory of the cleaning bristles covers the comb teeth. The beneficial effect of this is that when the comb teeth comb down hair, the rotating cleaning bristles can immediately sweep it away, preventing hair from accumulating and getting stuck at the base of the comb teeth, thus eliminating the need for manual cleaning and making it more convenient to use.

[0013] As an embodiment of the above solution, the reciprocating drive unit includes a linear reciprocating motor. The number of linear reciprocating motors is the same as the number of comb units, and they are linked and coupled one-to-one. When there are two comb units, under the drive of the corresponding linear reciprocating motors, the reciprocating motion of one comb unit and the other comb unit are set to be in opposite phases. The advantage of this is that the linear reciprocating motor directly outputs power to the comb unit in a linear reciprocating manner, resulting in a simple structure. The linear reciprocating motor provides power and can directly determine the motion trajectory of the comb unit.

[0014] As an embodiment of the above solution, it also includes a cleaning mechanism and a power motor for driving the cleaning mechanism to rotate; the cleaning mechanism includes a support base and cleaning bristles distributed and installed on the support base in a circumferential direction; the support base is linked to the power motor, and the rotation trajectory of the cleaning bristles covers the comb teeth.

[0015] Secondly, the present invention also provides an electric hair comb, wherein the electric hair comb is equipped with a reciprocating comb assembly as described in any one of the first aspects of the invention. The beneficial effect of this is that the electric hair comb equipped with the aforementioned reciprocating comb assembly can reduce the labor intensity of the user and improve the efficiency of combing.

[0016] To further optimize this technical solution, the electric hair comb is equipped with a hair-suction air duct. The air inlet of the air duct is positioned to match the position of the comb teeth unit, used to suck away the hair combed under the comb teeth during operation. The air outlet of the air duct is connected to a negative pressure air source to expel the hair. The beneficial effect of this is that the combed hair can be collected instantly by the negative pressure air source, making it less likely to accumulate and get tangled on the comb teeth.

[0017] To further optimize this technical solution, the electric hair comb is equipped with a battery to power the drive unit and a control circuit. This eliminates the need for an external power source, making it more convenient to use. Attached Figure Description

[0020] like Figure 1 As shown, this embodiment provides a reciprocating comb assembly, including: a comb tooth unit and a reciprocating drive unit; The comb unit includes a comb plate 2 and a plurality of comb teeth 1, wherein the comb teeth 2 are fixed on the comb plate 1; The reciprocating drive unit is connected to the comb plate 2 for driving the comb tooth unit to reciprocate along a preset combing trajectory.

[0021] The combing trajectory refers to the path of the comb teeth as they reciprocate along the working surface or parallel to it, not perpendicular to it. Movement perpendicular to the working surface is a pressing motion, while reciprocating movement parallel to or on the working surface constitutes the combing action. The working surface can be animal fur, human skin, or any other surface requiring combing.

[0022] Reciprocating motion can be linear reciprocating motion, oscillating reciprocating motion at a certain angle, or a periodic reciprocating motion composed of several combined motions. Since pet fur generally has a natural tilt direction, brushing involves brushing with the grain, brushing against the grain, and brushing at an angle. The relationship between the direction of the reciprocating motion and the natural tilt direction of the pet's fur is that the closer the motion is to the natural tilt direction, the less resistance there is, and vice versa. The greater the resistance, the greater the friction between the comb teeth and the fur, and the more fur is removed. Different pets adapt differently to brushing resistance, and the preset reciprocating motion trajectory can be tailored to these mechanisms.

[0023] like Figure 2 As shown, this embodiment is further optimized by using two comb tooth units, with the reciprocating motions of the two comb tooth units arranged in opposite phases. The beneficial effect of this is that when the two comb tooth units comb the hair together, the opposite motion phases cancel out the two reaction forces on the working surface, reducing the overall sway of the pet and the reciprocating comb assembly, and also facilitating stable operation for the operator.

[0024] like Figure 2 and Figure 3 As shown, this embodiment is further optimized. The reciprocating drive unit includes a drive motor 3, a support frame 4, and eccentric shafts 5 in the same number as the comb units. The drive motor 3 is mounted on the support frame 4. The power output shaft 11 of the drive motor 3 is coupled and linked to each comb unit through an eccentric shaft 5. The eccentric shaft 5 is eccentrically connected to the power output shaft 11. The eccentric shaft 5 is concentrically rotatably connected to the corresponding comb plate 2. When there are two comb units, the eccentric shafts 5 corresponding to the two comb units are distributed vertically in the axial direction of the power output shaft 11 and are set in opposite phases. Each comb plate 2 and the support frame 4 are respectively provided with a limiting pair 6, which is used to guide the reciprocating motion of the comb unit.

[0025] In terms of specific configuration, the eccentric shaft 5 is provided with an eccentric hole, the power output shaft 11 passes through the eccentric hole and is fixedly connected to the eccentric shaft 5, and the outer side of the eccentric shaft 5 is rotatably connected to the comb plate 2 through the bearing 19 to reduce frictional resistance and noise.

[0026] like Figure 3 As shown, in one embodiment of the above scheme, both limiting pairs are linear and symmetrically distributed in the diameter direction of the power output shaft.

[0027] like Figure 4 As shown, as an embodiment of the above scheme, both limiting pairs are S-shaped and symmetrically distributed in the diameter direction of the power output shaft. The S-shape here is not limited to the literal "S" shape, but can be a continuous wave shape, sine wave, zigzag line, or similar shape.

[0028] like Figure 1 or Figure 2 As shown, the structure of the limiting pair can be: the limiting pair includes a guide rod 20 and a guide rail 21, and the guide rod 20 can slide along the length direction of the guide rail 21. To reduce the sliding noise of the guide rod 20 within the guide rail 21, two noise reduction methods are used: a) improve the assembly accuracy of the guide rod 20 and the guide rail 21, reduce the wobble gap, and fill with noise-reducing grease. b) use a flexible material for the contact surface of the guide rod 20 and the guide rail 21 to reduce wobble noise.

[0029] like Figure 1 or Figure 2 As shown, in one embodiment of the above solution, the comb plate 2 includes a base plate 7 and a connecting plate 8. The comb teeth 1 are fixed on the connecting plate 7, and the connecting plate 8 is detachably connected to the base plate 7. This design allows for the replacement of comb teeth with different lengths, thicknesses, curvatures, and densities, improving adaptability to different application scenarios.

[0030] like Figure 5 As shown, as an embodiment of the above solution, it also includes a cleaning mechanism, which includes a support base 9 and cleaning bristles 10 distributed and installed on the support base 9 in a circumferential direction; the support base 9 is linked to the power output shaft 11, and the rotation trajectory of the cleaning bristles 10 covers the comb teeth 1.

[0031] To ensure that the sweeping bristles 10 of the cleaning mechanism can cover the comb teeth 1 during rotation, the comb teeth 1 can be arranged in an array around the support base 9. The sweeping bristles 10 of the cleaning mechanism can also extend in a direction perpendicular to the working surface to directly sweep away loose hair on the pet's skin.

[0032] like Figure 6 As shown in the figure, as an embodiment of the above solution, the reciprocating drive unit includes a linear reciprocating motor 12. The number of linear reciprocating motors 12 is the same as the number of comb units, and they are linked and coupled one-to-one. When there are two comb units, under the drive of the corresponding linear reciprocating motor 12, the reciprocating motion of one comb unit and the other comb unit are set to be in opposite phases. The advantage of this is that the linear reciprocating motor 12 directly outputs power to the comb unit in a linear reciprocating manner, which is simple in structure. The linear reciprocating motor provides power and can directly determine the motion trajectory of the comb unit.

[0033] As an embodiment of the above solution, it also includes a cleaning mechanism and a power motor 13 for driving the cleaning mechanism to rotate; the cleaning mechanism includes a support base 9 and cleaning bristles 10 distributed and installed on the support base 9 in a circumferential direction; the support base 9 is linked with the power motor 13, and the rotation trajectory of the cleaning bristles 10 covers the comb teeth.

[0034] like Figure 7 , Figure 8 , Figure 9 As shown, in a second aspect, the present invention also provides an electric hair comb, wherein the electric hair comb is equipped with a reciprocating comb assembly as described in any one of the first aspects of the invention. The beneficial effect of this is that the electric hair comb equipped with the aforementioned reciprocating comb assembly can reduce the labor intensity of the user and improve the efficiency of combing.

[0035] To further optimize this embodiment, the electric hair comb is equipped with a hair-suction air duct 14. The air inlet 15 of the hair-suction air duct 14 is positioned to match the comb tooth unit, and is used to suck away the hair combed by the comb teeth 1 during operation. The air outlet 16 of the hair-suction air duct 14 is used to connect with a negative pressure air source to discharge the hair. The beneficial effect of this is that the combed hair can be collected immediately by the negative pressure air source, and is less likely to accumulate and get tangled on the comb teeth.

[0036] Negative pressure air source can be an external vacuum cleaner or a dedicated vacuuming mechanism can be integrated into an electric hair comb.

[0037] In a further optimization of this embodiment, the electric hair comb is equipped with a battery 17 to power the drive unit and a control circuit 18. This eliminates the need for an external power source, making the electric hair comb more convenient to use.

[0038] In the control circuit, different grooming speed levels can be set according to the pet's habits. This is a mature electronic control technology solution, and the circuit diagram can be omitted.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0040] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
