APPARATUS
Technical Field
[1] The present invention relates to a vacuum induction head with a dust-beating apparatus for an electric vacuum cleaner, more particularly to a vacuum induction head with a dust-beating apparatus capable of elastically beating or striking the object to be cleaned, such as the bed mattress, the blanket, the carpet and the clothe, and efficiently and cleanly sucking and removing the dust (and/or the dirt, the bacteria such as the rat mites, and etc.) infiltrated into the object to be cleaned. Background Art
[2] Generally, an electric vacuum cleaner for the conveniency of cleaning is advantageously used to suck and clean the dust and the dirt on the floor of the building such as the house, the business room and/or the commercial business.
[3] Such a vacuum cleaner is effective to clean the dust and the dirt on the floor or the window frame, but is unfavorable to clean the bedding such as the bed mattress and the blanket, the carpet and the clothes.
[4] In fact, the dust and the dirt may be easily pierced into the woven structure of the bedding such as the bed mattress and the blanket, the carpet and the clothe.
[5] In such that case, it is difficult to clearly suck and remove the dust and the dirt pierced into the woven structure of the bedding, the capet and the clothe by a predetermined vacuum suction power of the vacuum cleaner only.
[6] Further, when a pet such as a dog and a cat is bred within the house, the dirt such as hairs and scurfs secreted from the pet may be easily penetrated inside of the bedding, the carpet and the clothes.
[7] Accordingly, if the bedding, the carpet and the clothes where the dirt secreted from the pet is unremoved is used daily, a skin ailments such as an atopic dermatitis and a respiratory disease may be caused harmfully in the human body.
[8] But, the dirt of the pet penetrated into the woven structure of the bedding, the carpet and the clothes can not be easily sucked and removed with the vacuum suction power of the vacuum cleaner only.
[9] Especially, the bed mattress is habitable by the rat mite caused the skin ailments and/ or the respiratory disease to the human body, the rat mite is not easily removed with the vacuum suction power of the vacuum cleaner.
[10] Further, when the sandy dust or the minute dust in the auto exhaust in the atmosphere and/or the smell of smoke sink into the woven structure of the clothes, it is difficult to
remove the dusts and/or the smell from the woven structure of the clothes by the vacuum suction power of the vacuum cleaner only.
[11] Recently, in consideration of such that case, an electrical magnetic solenoid or an electromagnet is applied into a suction head of the vacuum cleaner such that the object (namely, the bedding, the carpet and the clothe) to be cleaned can be pound by the vibration of the electrical magnetic solenoid or the electromagnet in order to remove the dust or the dirt in the object(that is, the cleaning object).
[12] Here, such the vacuum cleaner where the cleaning object is cleaned by the vibration of the solenoid or the electromagnet is preferable to a general cleaner where the cleaning object is cleaned by the vacuum suction power thereof only.
[13] However, because the surface of the cleaning object is repeatedly in contact with the vibration of the solenoid or the electromagnet, the dust the dirt, the rat mite and/or the smell in the woven structure of the cleaning object can not be satisfactorily removed.

[41] Herinafter, the present invention will now be described with reference to the drawings.
[42] Referring to Fig.l, a main casing 12 of a vacuum induction head 10 with a cleaning object beating apparatus according to the present invention is provided with a connecting tube 14 to connect to a retractable extension pipe (not shown) of a vacuum cleaner.
[43] A switch 16 which is installed on the surface of the main casing 12 enables to switch the electric power for operating the suction head to ON or OFF and adjust the cleaning object beating force in a range of high-, middle- or low-level.
[44] A power-on pilot lamp 16a on the surface of the main casing 12, which is composed of an light emitting diode(LED), indicates the electric power-ON status controlled by the switch 16.
[45] Furthermore, a plug receptacle port 18 on the sidewall of the main casing 12 is prepared for a plug 22a of a power supplying plug 22 of an only-purpose AC/DC converter 20.
[46] Here, the electric power ON/OFF switch and the dust beat power control switch may be installed on a predetermined location of the surface of the main casing 12, instead of the switch 16. Also, the AC/DC converter 20 may be builted in the main casing 12.
[47] Referring to Fig. 2, the main casing 12 is comprised with an upper case 12a and a lower case 12b which are detachably joined to each other.
[48] A plurality of internal screw-tapped holes 24b (showing only one in Fig. 2) are formed near the 4-corners of the upper case 12a, and a plurality of screw penetrating holes 24, corresponding to the internal screw-tapped holes 24b, are formed on the lower case 12b so that the internal screw-tapped holes 24b and the screw penetrating holes 24 are correspondingly joined to each other by a plurality of screws 24a in order to couple the upper case 12a and the lower case 12b detachably.
[49] In addition, a plurality of movable wheels 28 for moving the vacuum induction head
10 in front or rear are installed through the corresponding one of the wheel exposure openings 26 formed at the front side and the rear side of the lower case 12b.
[50] Figs. 3 and 4 show a typical example of movable wheels equipped in the vacuum
induction head with a dust-beating apparatus according to the present invention shown in Fig. 2.
[51] Referring to Figs. 3 and 4, the middle portion of the respective wheel supporter 32, formed at both sides of the opening 28, is defined as a bearing receipt half-round 34 for correspondingly receiving a rotatable bearing 36 which is installed at the respective end of the movable wheel 28 so as to support the rotation of the movable wheel 28.
[52] Screw holes 32a for setting the bearing 36 are provided on both sides of the bering receipt half-round 34, and wheel bearing fixtures 38 are formed in correspondence with the wheel supporter 32.
[53] The middle portion of the respective wheel bearing fixture 38 is defined as a bearing supporting half-round 38 for correspondingly receiving the bearing 36 and, on both sides of the respective wheel bearing fixture 38, screw holes 38a are formed in correspondence with the screw holes 32a so that a screw 40 is penetrated through the corresponding screw hole 38 a.
[54] According to the present invention, it is not limited that the movable wheel 28 is outwardly exposed through the openings 26. That is, the movable wheel 28 may be installed at the outside of the main casing 12.
[55] Referring to Fig. 2, at the front of the lower case 12b, rotary drum brackets 42 are formed at a certain distance and, at the rear of the lower case 12b, a bracket 46 for supporting a cleaning object beating member to be described later is formed at a certain height.
[56] Moreover, a plurality of beating member passing holes 50 are formed between the rotary drum brackets 42 and the cleaning object beating member supporting bracket 46 so that the cleaning object beating member comprising a plurality of beating rods as described later elastically beats and strikes the cleaning object (for example, the bedding, the carpet, the clothes and etc.) through the beating member passing holes 50.
[57] Referring to Fig. 5 shown the principal part of the vacuum induction head with a dust-beating apparatus according to the present invention, each of the axes 56a and 56b of both ends of the rotary drum 56 is disposed the corresponding rotary drum bracket 42.
[58] In the middle portion of the respective rotary drum bracket 52, a rotary drum bearing
54 which is the corresponding axis 56a or 56b of the rotary drum 56 is receipted is provided for supporting the smooth rotation of the rotary drum 56.
[59] Preferably, according to the present invention, the peripheral surface of the rotary drum 56 is provided with at least one or more blade-type cleaning object beating member module lifting protrusions 60.
[60] An end of the rotary drum 56 is provided with a driven gear 58 (for example, a bevel gear) which is cooperated with the electric motor 16, and several gears 60 are formed
at a predetermined angle on the peripheral surface of the rotary drum 56.
[61] Here, according to the present invention, the location of the electric motor 16 for driving the rotary drum 26 is not limited as shown in Fig. 5. That is, the electric motor 16 may be mounted at any location which will be able to attain the technical essential of the present invention. Besides, it is possible to connect the electric motor 16 and the rotary drum 56 by means of an endless belt.
[62] Referring to Fig. 5, an end(that is, the rear side) of the cleaning object beating member module 62 is fixed to at the cleaning object beating member supporting bracket 46 on the lower case 12b.
[63] According to the present invention, the cleaning object beating member module 62 comprises a plurality of beating rods 62a and the respective beating rod has a front tip 62b which is formed upwardly.
[64] The electric motor 16 is fixed on the lower case 12b by tightening a screw (not shown) to the bracket fixture hole(not shown) formed in the fixture ribs 66a of the sides of the motor fixing bracket 66.
[65] And, the axis 64a of the electric motor 16 is provided with the driving gear 69 which is teethed with the driven gear 58 on the axis 56b of the rotary drum 56 and transfers the rotation force of the motor 16 to the rotary drum 56 through the driven gear 58.
[66] Accordingly, when the movable wheel 28, the electric motor 16, the rotary drum 56 and the cleaning object beating member module 62 are installed in the lower case 12b of the vacuum induction head of the present invention and the electric power is turned 'ON' by the switch 16, the electric motor 16 rotates in high-level, middle level or low- level adjusted by the switch 16.
[67] Then, the rotation power of the motor 16 is transmitted to the driven gear 58 through the driving gear 69 coupled to the motor axis 64a. Thus, the rotary drum 56 is rotated so that, due to the rotation of the rotary drum 56, the front tips 62b of the beating rods 62a are simultaneously raised and, thus, the elastic force is build up to the the beating rods 62a.
[68] On the other hand, when the front tips 62b of the beating rods 62a are detached from the cleaning object beating module lifting protrusions 60 of the rotary drum 56, the cleaning object (for example, the bedding, the carpet, the clothe and etc) beat elastically and strongly by the elastic force of the beating rods 62a and, then, the dust and/or the dirt from the cleaning object can be sucked through the connecting tube 14 of the vacuum induction head of the present invention.
[69] More particularly, when the rotary drum 56 is rotated from a condition where the tips
62b of the beating rods 62a of the module 62 is disconnected from the cleaning object beating member module lifting protrusions 60 of the rotary drum 56 as shown in Fig. 6, the tips 62b of the beating rods 62a are simultaneously raised by the cleaning object
beating member module lifting protrusions 60 of the rotary drum 56 as shown in Fig. 7.
[70] After, when the cleaning object beating member module lifting protrusions 60 of the rotary drum 56 are rotated over a predetermined angle, the tips 62b of the beating rods 62a are detached from the presently contacted cleaning object beating member module lifting protrusion 60 of the rotary drum 56 and falls elastically so as to beat the cleaning object through the beating member passing holes 50 as shown in Fig. 8.
[71] Accordingly, the dust and/or the dirt penetrated in the cleaning objet can be shaked off by the repetitive beating action of the beating rods 62a and, then, the dust and/or the dirt from the cleaning object can be sucked by the vacuum suction power of the vacuum cleaner connected to the vacuum induction head according to the present invention.
[72] Fig. 9 is a view showing another example of the cleaning object beating apparatus in the vacuum induction head according to the present invention.
[73] Referring to Fig. 5, the cleaning object beating member module lifting protrusion 60c which maintain a certain angle to each other are formed on the periphery surface of the rotary drum 56 such that the beating roads 62a can beat and dust off the cleaning object at the same time.
[74] In camparison with such that structure showin in Fig. 5, according to this example, a plurality of cleaning object beating member module lifting protrusions 60a which maintain a certain distance and location to each other are formed on the periphery of the rotary drum 56. Here, the number of the cleaning object beating member module lifting protrusions 60a are identical to the number of the beating roads 62a of the module 62.
[75] In the configuration of Fig. 9 described above, when the rotary drum 56 is rotated, the cleaning object beating member module lifting protrusions 60a formed in different locations can beat and dust off the cleaning object in time difference and in sequence.
[76] On the other hand, according to still another example of the cleaning object beating apparatus shown in Fig. 10 a side of the rotary drum 56 is eccentric on pivots 56a and 56b of both ends thereof and acts as a cleaning object beating member module lifting protrusion 60b for lifting the tips 62b of the beating rods 62a.
[77] According to the present invention, the formation and location of the cleaning object beating member module lifting protrusions (s) on the periphery surface of the rotary drum 56 shown in Fig.5 and Figs. 9 and 10 to can be variously changed if the elasticity operation of the beating roads (that is, beating member) 62a is achieved in accordance with the rotation of the electric motor 16.
[78] Fig. 11 shows a view showing a modified example of the cleaning object beating member in the vacuum induction head with a dust-beating apparatus according to the
present invetnion.
[79] In the example described above, the beating rods 62a of the module 62 are formed in generally linear and has the upwardly formed front tips 62b. But, according to this modified example, a bended portion 62c is formed at a predetermined location of the respective beating rod 62a in order to beat the cleaning object in enhanced elasticity force.
[80] Also, this modified example shows that if the front tip 62d of the dust beat body 62a is formed in a spherical shape or fitted with a separate spherical-shaped tip member, it is possible to prevent the damage of the surface or the woven structure of the cleaning object.
[81] Fig. 12 shows another modified example of the cleaning object beating module in the vacuum induction head according to the present invention.
[82] As seen from Fig. 12, the beating rods 70 are alined at regular intervals, and the front tips of the adjacent cleaning object beat rods 70 are integrated so as to enhance the elasticity force for the cleaning object.
[83] According to the present invention, in the afore-mentioned examples the cleaning object is beaten by the elasticity force of the module 62 accumulated from the rotation of the rotary drum 56 which is cooperated with the electric motor 16.
[84] But, if the beating rods may be formed on both sides of the rotary drum 56 and the electric motor may be rotated in clockwise or counterclockwise, it is possible that the cleaning object is alternatively beaten by the beating rods of the both sides of the rotary drum 56 in accordance with the clockwise- and counterclockwise-rotation of the electric motor 16.
[85] Fig. 13 is a view showing another embodiment of the cleaning object beating apparatus in the vacuum induction head according to the present invention.
[86] In the bottom of the lower case 80 corresponding to the lower case 12b, a plurality of beating rod passing and dust-suction openings 82 are formed at regular intervals for sucking the air including the dust and beating the cleaning object by the cleaning object beating module 86.
[87] At the sidewalls of the lower case 80, bearing receiving concaves 84 are formed to receipt the bearings 84a for supporting the rotation of the cleaning object beating module 86 having a plurality of beating rods 86b..
[88] In addition, a plurality of beating modul ascent and descent supporting shafts 84b which are aligned at regular intervals are formed at a predetermined position of the lower case 80 in order to guide the ascent and descent action of the beating module 86.
[89] In comparison with the beating member 62 and the beating module 70 of the aforementioned examples, the front and the rear of the beating module 86 of this embodiment are respectively integrated, and the beating rods 86b are branched off
between the front and the rear of the beating module 86.
[90] Nevertheless, it is possible that the beating module 86 is provided with the structure shown in Fig. 5 or the structure shown in Fig. 12.
[91] Moreover, pivotal projections 88 are formed at both sides of the beating module 86 and the respective pivot projection 88 is inserted in the central hole of the corresponding bearing 84a receipted in the respective bearing receiving concave 84.
[92] Several shaft guide openings 90 corresponding to the beat module ascent and descent supporting shafts 84b are defined at a predetermined location of the beating module 86. Furthermore, at least one spring supporting projection 92 is formed at a predetermined location of the beating module 86 in order to support the lower portion of an elastic spring 98 for elastically supporting the beating module 86.
[93] Referring to the drawing, a cover 96 is provided on the sidewalls and the rear- wall of the lower case 80. Both sides of the cover 96 are provided with several bearing supporters for preventing the bearings 84a to be escaped from the bearing receiving concaves 84.
[94] Further, at least one elastic spring 98 is installed between the lower surface of the cover 98 and the spring supporting projection 92 of the beating module 86.
[95] An electric motor 100 is mounted at a predetermined position of the lower case 80 and an axis 100a of the motor 100 is inserted in an axis receipt hole 102a of a rotary drum 102 which transfers the rotation power of the motor 100 to the beating module 86 so as to obtain the elasticity force for beating the cleaning object.
[96] Advantageously, the opposite sides of the rotary drum 102 are provided with several blade-shaped beatting module lifting protrusions 102b for lifting the tip 94 of the cleaning object beat body 86.
[97] According to the present invention, the formation shown in Fig. 5, Fig. 11 or Fig. 12 can be applied instead of the rotary drum 102 in accordance with the shape of the beating module 86 according to this embodiment.
[98] In the structure of the vacuum induction head according to the present invention, if the electric motor 100 rotates and, thus, the rotary drum 102 coupled to the axis 100a of the motor 100 is rotated cooperatively, the beating module lifting protrusions 102b of the rotary drum 102 are rotated and alternatively lift the front tip 94 of the beating moudle 86 so as to accumulate the elasticity force for beating the cleaning object.
[99] After, when the front tip 94 of the beating module 86 is depart from the presently- contacted beating module lifting protrusion 102b, the beating module 86 can be descended through the beating rod passing and dust-suction openings 82 and beats the the cleaning object elastically and stronly.
[100] In a series cleaning object beating operation of the beating module 86, if the front tip 94 of the body 86 is lifted by the beating module lifting protrusion 102b of the rotary
drum 102, the rotating operation of the pivot projections 88 of the module 86 are supported by the bearings 84a of the lower case 80.
[101] Also, during the front tip 94 is lifted by the beating module lifting protrusion 102b of the rotary drum 102, departs from the beat rod lifting protrusion 102b of the rotary drum 102 and elastically beats the cleaning object, the beating module 86 is elastically supported by the elastic spring 98.
[102] Accordingly, under the elastic support of the spring 98, the beating module 86 can repeatedly beat and clean the cleaning object in accordance with the rotation of the rotary drum 102 cooperated with the motor 100.
[103] Fig. 14 shows a typical vacuum cleaner applied with the cleaning object beating apparatus in the vacuum induction head according to the present invention.
[104] The vacuum cleaner 200 shown in the drawing is provided with a typical structure including a vacuum suction motor (not shown) for cleaning the cleaning object.
[105] Additionally, if the vaccum induction head (referring to '12' of Fig 1) acording to the present invention is detachably applied to the vacuum cleaner 200, it is possible that the cleaning object is beaten by the vacuum induction head 12 and simultaneously sucked by the vacuum suction motor of the vacuum cleaner 200.
[106] Fig. 15 shows another vacuum cleaner applied with the cleaning object beating a pparatus in the vacuum induction head according to the present invention.
[107] In such a case of the handy-type vacuum cleaner 300, the vacuum induction head (referring to '12' of Fig 1) of the present invention can be detachably or integrally applied on the front side or the front and lower side of the vacuum cleaner 300 so that the cleaning object is beaten by the vacuum induction head 12 and simultaneously sucked by the vacuum suction motor of the vacuum cleaner 300.
[108] Further, the suction cleaning of the vacuum cleaner 200 or 300 can be achieved even if the vacuum induction head 12 with the beat function described above is applied to the vacuum cleaner 200 or 300.
[109] While the present invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
[110] In the vacuum induction head of the present invention, if the beating module or the beating member can beat the cleaning object by the rotation force of the electric motor, the beating module or the beating member may be moldified in any structure.
[I l l] Also, the beating module or the beating member may be modified in a structure that the rear end is lifted so as to obtain the elasticity force for beating the cleaning body and, alternatively, it can be modified that the rotation power of the electric motor is directly transferred to the front of the beating module or the beating member.
[112] And, in the changes and modifications of the present invention, the beating member may be integrally formed on both sides of the rotary drum such that the cleaning object can be elastically beaten by the beating member of the rotary drum in accordance with the clockwise- and counterclockwise rotation of the electric motor.
[113] Alternatively, it is possible that a periphery surface of the rotary drum is provided with at least one rope-type beating member of flexible material (for example, synthetic resin) or at least one beating member using the elasticity force of the elastic spring such that the beating member is fully rotatable so as to beat the cleaning object.
[114] Advantageously, a sterilization unit including an ultraviolet lamp can be detachably or integrally at the front, the rear or the lower side of the suction head according to the present invention.
