BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic towel,

The present invention relates to an electronic towel having a flow path.

When you take a bath, your body will get water, sand, and other foreign matter. When wiping these foreign objects with a woven cloth (hereinafter referred to as "towel") so that the filigree room becomes fluffy, the water is not polished well and the sand is not washed away. It is a hassle to repel the sand repeatedly.

Accordingly, an electronic towel capable of wiping off foreign matter by wind and vibration is being developed. Such an electronic towel is not easily circulated in the inside of the body, resulting in noise due to use.

In addition, the air blown into the inside of the body is blown into the inside of the body by driving the blowing fan disposed inside the body. Foreign matter such as water, dust or sand contained in the air flows into the inside of the body when the outside air flows into the inside of the body.

1 to 5, an electronic towel 1 (hereinafter referred to as an electronic towel) having a flow path according to the present embodiment includes a body portion 10, a cover portion 50, a vibration portion 60, A nozzle unit 70 and a blower unit 80 to remove water and foreign matter from the skin using the vibration of the vibration unit 60 and the wind of the blower unit 80.

The body portion 10 includes a head 11 and a handle 12 and forms the outer shape of the electronic towel 1. [ The body part 10 can be made of a resin-based material and a coating layer (not shown) is formed on the outer surface of the body part 10 to prevent scratches and the like.

The front surface of the head 11 is opened. The cover portion 50 is detachably coupled to the open front face of the head 11. A known locking structure can be applied to the separable coupling structure of the cover portion 50 and the head 11, and a detailed description thereof will be omitted.

A plurality of nozzle holes 51 are formed in the cover portion 50 to connect the inside of the head 11 with the outside.

A vibrating space 111, a blowing space 113, a circulating flow path 114 and an air flow path 115 are formed in the inside of the head 11. And is formed as an outer corner curve of the head 11 and the cover portion 50. [

The vibrating space 111 and the air blowing space 113 are separated by an end 112 and an inner first circumferential surface 11a constituting the vibrating space 111 is connected to the front surface of the head 11. A mounting groove 11b is formed around the first peripheral surface 11a. In the step 112, the elastic insertion groove 112a is formed at a predetermined depth. The elastic insertion grooves 112a are formed at intervals along the longitudinal direction of the step 112. [

The air blowing space 113 is connected to the vibration space 111. A circulation flow path 114 is formed on an inner second circumferential surface 11c constituting the air blowing space 113. The air blowing space 113 has an inlet 114a connected to the air blowing space 113 and an outlet 114b connected to the air blowing space 113.

The air passage 115 is formed inside the head 11 to connect the air blowing space 113 and the rear surface of the head 11. [ The air passage 115 has an outlet 115b connected to the air inlet space 113 and an inlet 115a connected to the rear surface. The outside air of the electronic towel 1 can be introduced into the air blowing space 113 through the air blowing passage 115.

The inlet 115a is provided with a filter 116 for filtering foreign substances. The filter 116 prevents foreign matter from flowing into the airflow passage 115. The filter 116 may be formed in a lattice structure. For example, the filter 116 may be a COARSE SCREEN or FINE SCREEN structure.

A recovery hole 117 is formed in the air passage 115. A suction member 117a formed of a sponge or a nonwoven fabric is disposed in the recovery hole 117. [ The recovery hole 117 is formed so as to be perpendicular to the imaginary center line C in the longitudinal direction of the airflow passage 115. The recovery hole 117 is positioned below the imaginary center line C of the airflow passage 115 with respect to the rear surface of the head 11. [ Water, foreign matter, and the like contained in the air moving along the air passage 115 may be introduced into the recovery hole 117. The water foreign matter can be adhered to the adsorption member 117a. Therefore, the water and the foreign matter introduced into the recovery hole 117 can not move along the airflow passage 115. Only the purified air can be introduced into the air blowing space 113.

The handle 12 is connected to the rear surface of the head 11 and is formed in a structure that can be gripped by the user. A circuit device 20, a power supply 30, and the like, which are electrically connected to each other, are disposed inside the handle 12. The power supply unit 30 may be a rechargeable battery. The power supply unit 30 is not limited to a battery.

The power supply unit 30 can be charged and replaced. A switch 40, which is electrically connected to the circuit device 20, is disposed on the outer circumferential surface of the knob 12. The circuit device 20 and the power source unit 30 are protected by a sealing member (not shown) so that foreign matter can not penetrate.

The vibrating portion 60 includes a plate 61, a plate sealing member 62, an elastic member 63, an elastic sealing member 631, an insertion pin 64 and a vibration generating portion 65.

The plate 61 has a predetermined width and is disposed in the vibration space 111. [ Although the plate 61 is shown as a flat structure in the drawing, the plate 61 may be formed in a wave shape. The wavy plate 61 can be improved in tremor.

A plurality of coupling holes 61a are formed in the plate 61 along the longitudinal direction Y with a gap therebetween along the width direction X. As shown in FIG. The engaging hole 61a coincides with the nozzle hole 51. [ In FIG. 2, four coupling holes 61a are shown, but the number of coupling holes 61a may vary depending on the design of the electronic towel 1. [

6, the plate sealing material 62 can be made of rubber or the like, and is coupled to the edge of the plate 61. As shown in Fig. The plate sealing member 62 is inserted into the mounting groove 11b and the plate 61 is fixed to the body portion 10. [ The plate 61 can be shaken while being fixed to the body part 10. [

The vibration of the plate 61 is not transmitted to the body portion 10 by the plate sealing material 62. The plate sealing member 62 is in contact with the body portion 10 so that noise due to the vibration of the plate 61 does not occur when the plate 61 vibrates.

The elastic member 63 is disposed at a portion of the plate 61 facing the end 112 and is inserted into the elastic insertion groove 112a. The elastic member 63 prevents the vibration of the plate 61 from being transmitted to the body 10 when the plate 61 is fixed to the body 10.

The elastic sealing member 631 is engaged along the outer circumferential surface of the elastic member 63 so that the elastic member 63 is not in contact with the body portion 10. [

The insertion pin 64 is engaged with the elastic member 63 and connects the elastic member 63 and the plate 61. The insertion pin 64 can be inserted into the elastic insertion groove 112a.

The vibration generating portion 65 is disposed on the plate 61 and is electrically connected to the circuit device 20. [ When the circuit device 20 applies a signal to the vibration generating section 65 by the operation of the switch 40, the vibration generating section 65 can be turned on / off according to the signal. The detailed structure of the vibration generating unit 65 can be applied to a well-known brushless vibration motor, and a detailed description thereof will be omitted.

Vibration may be generated as the plate 61 is vibrated by the vibration generating unit 65. [ The vibration force of the plate 61 can be improved by the elastic member 63 and the wave shape. The vibration of the plate 61 is transmitted to the body portion 10 by the plate sealing material 62 and the elastic member 63. [ Since the plate 61 is not in direct contact with the body 10, the noise generated between the plate 61 and the body 10 when the plate 61 is shaken is reduced.

The nozzle unit 70 includes a nozzle panel 71, a nozzle member 72 and a roof file 724 and can blow air in the air blowing space 113 and shake or shake the skin.

The nozzle panel 71 has a predetermined length as a base of the nozzle unit 70 and is disposed for each coupling hole 61a and is coupled to the plate 61. [ The nozzle panel 71 can be shaken along the plate 61. The nozzle panel 71 can be detached from the plate 61. The nozzle panel 71 is formed with a mounting hole 71a that coincides with the nozzle hole 51 at intervals along the longitudinal direction.

The nozzle member 72 includes an inner nozzle 721, an outer nozzle 722, and a corrugated tube 723, and is capable of jetting air and knocking the skin. A plurality of nozzle members 72 are formed and are coupled to the mounting holes 71a. A plurality of nozzle members 72 are coupled to the nozzle panel 71 so that a plurality of nozzle members 72 can be quickly coupled to the vibrating unit 60.

The inner nozzle 721 is disposed for each mounting hole 71a and is coupled to the nozzle panel 71, and the inside thereof is vertically penetrated. The inside of the inner nozzle 721 is connected to the air blowing space 113. The inner nozzle 721 may be shaken along the nozzle panel 71.

The outer nozzle 722 is coupled to each nozzle hole 51 and has an inner space. The outer nozzle 722 is formed with a plurality of ejection holes 722a for connecting the inside and the outside. The injection hole 722a is formed in such a manner that the cross-sectional area gradually decreases from the inside of the outer nozzle 722 toward the outer side. The speed of the air injected from the injection hole 722a can be increased.

At least a part of the inner nozzle 721 is inserted into the inside of the outside nozzle 722. The outer periphery of the inner nozzle 721 and the outer periphery of the outer nozzle 722 are apart. The cross section of the end of the outer nozzle 722 is formed in a circular shape. The shape of the end of the outer nozzle 722 is not limited to a circular shape. The nozzle member 72 can be formed into various shapes according to the design of the nozzle member 72.

The corrugated tube 723 connects the inner nozzle 721 and the outer nozzle 722. The bellows pipe 723 can be increased or decreased when the inner nozzle 721 is shaken. The outer nozzle 722 and the inner nozzle 721 are connected to the bellows tube 723 so that the shaking of the plate 61 is not interfered with the nozzle member 72. Therefore, the plate 61 can be easily shaken. The vibration of the inner nozzle 721 is not transmitted to the outer nozzle 722 due to the movement of the corrugated tube 723. [ However, the outer nozzle 722 may be shaken together with the body portion 10 by the cover portion 50.

A plurality of contact protrusions 725 are formed on the outer circumference of the outer nozzle 722. The cross-sectional shape of the contact protrusion 725 is circular. The contact protrusions 725 come into contact with the skin, and water, foreign matter, and the like can be removed.

The loop file 724 is disposed around the outer periphery of the outer nozzle 722. The loop file 724 may be in contact with the skin. The loop file 724 can shake out foreign matter adhering to the skin. The loop file 724 may be made of silicon or the like which is harmless to the human body. Loop file 724 is not limited to silicon. A variety of materials can be applied if the loop file 724 is a material that can feel a soft touch when it contacts the skin.

On the other hand, a plurality of contact protrusions 725 capable of contacting the skin are formed on the outer periphery of the outer nozzle 722. The cross-sectional shape of the contact protrusion 725 is circular. The contact protrusion 725 can come into contact with the skin together with the loop file 724 to shake foreign matter.

The blowing section 80 includes a motor 81 and a blowing fan 82 and is disposed in the outlet 114b of the circulating flow passage 114 and fixed inside the head 11. [ The airflow 80 forms air to be sprayed through the nozzle portion 70.

The motor 81 is fixed inside the head 11 and electrically connected to the circuit device 20. [ The motor 81 can be operated together with the vibration generating portion 65 by the operation of the switch 40. [ The motor 81 is also protected by a sealing member.

The air blowing fan 82 is disposed in the air blowing space 113 and connected to the motor 81. Air can be injected from the injection hole 722a by the operation of the blowing fan 82. [

The following describes the operation of the electronic towel described above.

When the user operates the switch 40, the vibration generating portion 65 vibrates as the plate 61 vibrates. The outer nozzle 722, the loop pile 724, and the like are shaken by the vibration, and the skin can be shaken when the skin is contacted. Water on the skin, foreign matter, etc. may fall off the skin. The outer nozzle 722 and the inner nozzle 721 are connected to each other by the bellows tube 723 so that the vibration of the vibration unit 60 transmitted to the inner nozzle 721 is not transmitted to the outer nozzle 722. Thus, the impact applied to the skin by the vibration is minimized. In addition, the inner nozzle 721 can freely move by the corrugated tube 723, and vibration of the vibration portion 60 can be smoothly performed. That is, the plate 61 can shake well without resistance from the outside.

When the blowing fan 82 is rotated by the operation of the motor 81, the outside air of the electronic towel 1 moves along the air passage 115 through the inlet 115a and flows into the air blowing space 113 through the outlet 115b Can be introduced.

The foreign substances contained in the outside air are primarily filtered by the filter 116. When the outside air moves along the air blowing passage 115, foreign substances contained in the air are introduced into the recovery hole 117 and adsorbed to the adsorption member 117a . So that the purified air can be introduced into the air blowing space 113.

The air in the inflow air space 113 can be injected into the swinging skin of the body part 10 through the inner nozzle 721, the corrugated tube 723 and the injection hole 722a of the outer nozzle 722. [ Therefore, water, foreign matter, and the like on the skin can be removed from the skin.

7, the air not blown out through the nozzle unit 70 is circulated through the inlet 114a because the air blowing unit 80 is located at the outlet 114b of the circulating flow path 114. Therefore, Flows into the flow path 114 and flows into the air blowing space 113 again through the outlet 114b. Thus, air in the air blowing space 113 and the circulating flow path 114 can circulate. It is possible to strongly blow out the noise and wind generated when the air is circulated in the air blowing space 113 by the air circulation in the air blowing space 113 and outside the air blowing space 113 strongly.

Therefore, the electronic towel 1 according to the present embodiment shakes the skin with water, foreign matter, and the like, blows it with the wind, and the skin can be defensive. There is no need to wash the shower several times or wash it with a towel several times.

In addition, the air that can not be blown to the outside during the operation of the blowing unit (80) can be discharged to the outlet through the inlet of the circulating flow path (114). Accordingly, the air in the air blowing space 113 can circulate and no noise is generated due to the air being accumulated in the air blowing space 113.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
