In some embodiments, the outer diameter of the upper end of the comb core 10 is smaller than the outer diameter of the lower end of the comb core 10.

Specifically, the outer diameter of the lower end of the comb core 10 is larger than the outer diameter of the upper end. This design enables the water absorbing layer 20 to be nested from the upper end of the comb core 10, and at the same time, the outer layer 20 can be restricted due to the larger outer diameter of the lower end of the comb core 10. The distance to slide down. Meanwhile, it should be noted that the inner diameter of the opening of the lower end of the water absorbing layer 20 is smaller than the maximum outer diameter of the lower end of the comb core 10.

In some embodiments, the inner diameter of the lower end of the blocking member 30 is larger than the outer diameter of the upper end of the comb core 10 and the water absorbing layer 20, which is smaller than the outer diameter of the comb core 10 and the lower end of the water absorbing layer 20.

In some embodiments, the bottom of the blocking member 30 is disposed 5-15 mm below the topmost end of the comb core 10.

In some embodiments, after the fastener 40 is formed, the interior thereof cooperates with the upper end of the water absorbing layer to form a resistance portion for preventing the fastener from moving up or down.

Specifically, after the fixing member 40 is formed, the clamping member 20 itself exerts a force on the water absorbing layer 20, but the fixing member 40 itself may still move up and down by relying on the force, and the fixing member 40 and the water absorbing layer may be caused for a long time. 20 and the upper end of the comb core 10 are disengaged, so that the inside of the fixing member 40 cooperates with the upper ends of the comb core 10 and the water absorbing layer 20 to form a resistance portion for preventing the fixing member from moving up or down. For example, the comb core 10 and the water absorbing layer 20 are covered by the upper end of the fixing member 40, and the diameter thereof is larger than the bottom diameter of the fixing member 40, so that the comb member 10 and the water absorbing layer 20 are moved in the upward movement of the fixing member 40. The upper end portion where the fixing member 40 is wrapped may block the bottom of the fixing member 40.

In the actual use, since the fixing member 40 and the upper ends of the comb core 10 and the water absorbing layer 20 are not adhered, the movement of the fixing member 40 and/or the movement of the upper end of the water absorbing layer 20 cannot be completely eliminated, but even if there is Moving, the moving distance is small, and the inside of the fixing member 40 cooperates with the comb core 10 and/or the upper end of the water absorbing layer 20 to block the movement of the fixing member 40, and the fixing member 40 and the upper end of the comb core 10 The force blocks the movement of the upper end of the water absorbing layer 20. It does not affect the product, whether in use or aesthetically.

It is also possible to provide a blocking member inside the comb hole. After the limiting block 23 is inserted, the blocking member limits the limiting block 23 to the inside of the comb hole. In some embodiments, the lower end of the limiting block 23 has a design that cooperates with the blocking member. For example, the blocking member is a kind of barb type protrusion, and the bottom of the limiting block 23 has a small hole or a small hole, and the small hole Or the inside of the small hole has a concave position matching with the barb of the blocking member, the blocking member is inserted into the small hole at the bottom of the limiting block 23, the top end of the blocking member can restrict the downward movement of the limiting block 23, and the barb type of the blocking member The design cooperates with the recess in the aperture to limit the restriction block 23 from moving upward.

8 to 11 are schematic views of a fourth embodiment of the present invention. In this embodiment, the water absorbing layer is deformed in the upper end of the comb core to form an elbow, and then extends downward to connect with the base, and the elbow forms a fixing structure of the water absorbing layer and the comb core. As shown in Fig. 8, the water absorbing layer 20 is disposed outside the comb core 10, and is redirected at the upper end of the comb core 10 to form a plurality of water absorbing portions 21. The left water absorbing portion 21, the right water absorbing portion 21, and the top elbow water absorbing portion 21 are included. The top elbow water absorbing portion 21 changes direction to form an elbow.

As shown in Fig. 9, a steering head 11 for steering the water absorbing layer may be provided at the upper end of the comb core, and the steering head may be integrally formed with the comb core or may be a separate member connected to the comb core. The water absorbing layer cooperates with the comb core to change direction along the steering head at the upper end of the comb core 10.

With this structure, the elbow portion of the comb core can also support the water absorbing layer 20.

Moreover, the water absorbing layer 20 is unbroken at the top end of the comb core so as not to cause the raw material of the water absorbing material to be scattered, for example, the spread of the water absorbing layer yarn and the burrs.

In some cases, at least one comb has a cushioning member for buffering the force of the water absorbing layer 20 and the comb core at the upper end. For example, if the comb teeth are fine, the water absorbing layer 20 is easily deflected when the upper end of the comb core is turned. The small upper end of the comb core 10 is punctured or damaged, and the action of the cushioning member isolates the upper end of the comb tooth from the water absorbing layer or at least acts as a buffer. In the actual processing, the buffer member is generally connected to the comb teeth, for example, a cushioning member is inserted into the top end of the comb tooth, and the water absorbing layer is placed on the comb tooth, so that the comb tooth is also covered by the water absorbing layer. In general, the cushioning member is a material having a certain flexibility, such as silica gel.

In some cases, a pressure reducing member may also be disposed at the top of the water absorbing layer, and the pressure reducing member is generally at the upper portion of the water absorbing layer. When the water absorbing layer is in contact with the hair or the scalp, the pressure reducing member can reduce the hair or scalp to the water absorbing layer. Rub to avoid damage to the top of the absorbent layer. In general, the pressure reducing member is a material with a certain flexibility, such as silica gel.

In the above embodiment, the water absorbing layer may be provided with a fixing snap ring on the side close to the base, which further functions as a fixing.

At this time, the evaporation member matched by the water absorbing layer can make During the use of the water absorbing layer, the water absorbed by the water absorbing layer 20 is accelerated and evaporated by driving the evaporation member, so that the water absorbing ability and the water absorbing speed of the water absorbing layer 20 are greatly enhanced, and the water vapor generated by the evaporation also passes through the water absorbing layer. The layer and hair contact is transferred to the hair to provide a conditioning effect on the hair.

The water absorbing layer 20 absorbs water to drive the evaporation member, and can accelerate the evaporation of moisture of the water absorbing layer 20 after use, thereby avoiding problems caused by the water absorbing layer 20 due to moisture, such as moistureing the articles in contact with it when stored, or the user may It is feared that the water absorbing layer 20 containing moisture absorbs bacteria and the like.

Specifically, the heater 70 is a heating source, and the heater is preferably a PTC heater. The heater 70 is connected to the power module 60 and is powered by the power module 60. The power module 60 can be powered by a battery disposed within the susceptor 50, or can be powered by a power line connected to an external power source. The metal heating portion is connected to the heater 70, and the moisture of the water absorbing layer 20 is evaporated by heat. Preferably, the metal heating portion may be a comb core of a metal material, such that heat of the metal heating portion may preferably act on the suction layer 20.

In some embodiments, the metal heating portion is a metal material such as aluminum, which is at least partially disposed in a part or all of the interior of the comb core, such that the heat of the metal heating portion acts on the water absorbing layer 20, such as a comb. There is a hole outside the tooth core, and heat is transmitted to the water absorbing layer through the hole.

The moisture of the water absorbing layer 20 is evaporated by heat. In general, the higher the temperature, the larger the evaporation amount under the same area, and the faster the evaporation rate. Since the water absorbing layer 20 is a flexible material, the heat resistance is limited, so the contact temperature of the metal heating portion and the water absorbing layer 20 is generally Between 40 and 120 degrees Celsius, below 40 degrees, the evaporation effect of the metal heating portion on the water absorbing layer 20 is very limited; above 120 degrees, the temperature of the metal heating portion may cause damage to the water absorbing layer 20, which is reduced. The use time of the water absorbing layer 20.

In the embodiment shown in FIG. 13, the evaporating member includes: a power module 60 disposed in the susceptor, a wind source member 80 connected to the power module for generating wind power, and a communication with the wind source member 80. In the air outlet channel of the water absorption layer, the air outlet channel is disposed on the comb core. Preferably, the air outlet channel is a comb core 10 .

Specifically, the lower end of the comb core 10 is hollow inside, and at the same time, the side of the comb core 10 also has an air outlet, which is connected to the wind source component 80 disposed in the base through a wind channel, such as a closed duct, and the power module 60 is the wind source component 80. Provide power. The power module 60 can be powered by a battery disposed within the susceptor 50, or can be powered by a power line connected to an external power source.

The power module 60 provides power to the wind source component 80. The wind source component 80 generates wind power, and reaches the air outlet channel through the wind channel. The wind power transmitted by the air outlet channel contacts the water absorbing layer 20, and the wind force cooperates with the water absorbing layer 20. The moisture of the water absorbing layer 20 is evaporated.

In general, the outlet passage is a comb core 10, and in some embodiments the outlet passage and the comb core 10 are different, for example, to reduce the loss of wind during transportation, and a closed hose is used as the outlet. The passage connects the wind source member 80 and the comb core 10, but even in this case, the comb core 10 transmits at least a portion of the wind to the water absorbing layer 20.

In general, the higher the wind speed, the greater the evaporation in the same area, the faster the evaporation rate, but the speed is too high, the energy consumption increases, and it acts on the water absorbing layer 20, unlike the air outlet of the hair dryer. Therefore, the wind speed of the wind is about 5-20 meters per second. Below this speed, the evaporation of the water-absorbing layer 20 by the wind component and the wind channel is limited. Above this speed, the wind component and the wind channel are the water-absorbing layer. 20 may also cause damage, or the wind may be blocked by the water absorbing layer 20, causing backflow and affecting the evaporating components.

In actual operation, the evaporating component can also be implemented simultaneously with the heating component and the wind component, so that it is good in the use effect, that is, equal to the wind and the heat together to accelerate the evaporation of the moisture of the water absorbing layer.

The above is only the specific embodiment of the present invention. It should be noted that any modifications, equivalents, and variations made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
