FIELD OF THE INVENTION 
     The present invention relates to a vapor cleaning device. A boiler is installed within a case for boiling water. Then by a high temperature tolerant conduit, the vapor is guided to a cleaning tool, and then the vapor molecules will adhere to the molecules to be cleaned so as to remove the undesired particles for cleaning. 
     BACKGROUND OF THE INVENTION 
     In cleaning, it is often that the dust or other particles must be removed by vapor for full cleaning. Moreover, in the cleaning process, many cleaning tools, such as, brushes, scrapers, etc., are necessary. The cleaning devices on the market cannot provide all these functions in one device. This will cause inconvenience in cleaning. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention is to provide a vapor cleaning device. A boiler is installed within a case for boiling water, water is boiled by the boiler, and then by a high temperature tolerant conduit, heat from the vapor is guided to a cleaning tool. The vapor molecules will adhere to the molecules to be cleaned so as to remove the undesired particles. 
     Another object of the present invention is to provide a vapor cleaning device, with a neck portion and a connecting portion applied to a holder, an extension piece, and a cleaning tool, such as a brush, a scraper, nozzle, etc. Moreover, the extension piece serves to extend the cleaning tool for cleaning a higher place. 
     A further object of the present invention is to provide a vapor cleaning device having a strip on the case thereof and having a compact boiler for being carried by hands or on the back. 
     The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to FIG. 1, the vapor cleaning device of the present invention is illustrated. The vapor cleaning device according to the present invention includes an upper cover  3  and a lower cover  1  forming a case, a boiler  2  within the case, and a conduit  23  connected to holder  4  and the boiler  2  through the upper cover  3 . Two opposite sides of the upper cover have notches  30 , respectively. The front and rear ends of the upper cover are formed with attachment buckles  35 , respectively. The front buckle  35  is integrally connected to the adjacent channel  34  so that by a buckle  35 , a strip  33 , two ends of which have respective attachment rings  331 , is connected to the case. Thus, the present invention can be carried by hands or on the back. The top of the upper cover  3  has a groove  32  with a switch and a hole  31  aligned with water post  211  for filling water. 
     With reference to FIGS. 1 and 2, the inner bottom of the lower cover  1  has a ring shape enclosing frame  11  for receiving the boiler  2  formed by a boiler cover  21  and a boiler body  22  through screwing connection. Lower cover  1  has four positioning posts  12 . An assembling post  16  runs across the upper ends of two positioning posts  12  so that two assembling posts  16  can clamp the boiler  2  in position. Two sides of the lower cover  1  have notches  10  at positions aligned with respective notches  30  in the upper cover in order that two free rotary wheels  15  can be assembled between the two notches  30  and  10 . At the near end of the lower cover  1  a bottom pad  14  is installed by an enhancing block  13 . A groove for receiving a line box  25  is installed near the enhancing block  13 . 
     The boiler cover  21  has a water post  211  for filling water. After a proper amount of water has filled into the boiler  2 , the threaded over  20  serves to cover the post. A nozzle  212  is installed at another place of the boiler cover  21  and is connected with a conduit  23  for guiding vapor outwards. With reference to FIG. 3, the bottom view of the boiler body  22  is illustrated. A round concave portion is formed at the center of the bottom. A connecting body  222  shown in FIG. 3 is installed in a non-concave place for connecting to a temperature controlled switch and fixedly installed to the bottom of the boiler body  22  as shown in FIG. 3. A silicon rubber ring is arranged between the boiler cover  21  and the boiler body  22 . Ring  28  is formed with a trench for properly clamping the upper rim of the enclosing frame  11 . 
     The switch  24  as shown in FIGS. 1 and 2 is firmly secured to the inner top portion of the upper cover  3  of the case and protrudes through the groove  32 . The switch  24  is connected to a power wire and the boiler  2  by a fuse  26  and a temperature controlled switch  27  for providing a dual protection as shown in FIG.  12 . 
     The conduit  23  protrudes from the opening  34  on the upper cover  3  and a buffer cover  233  is fixedly installed on the conduit  23  and in the opening  34  so as to present a buffer effect between the conduit  23  and the outer rim of the opening  34  for preventing damages to the conduit  23 . An outer tube  234  for isolating heat encloses part of the conduit  23  exposed outwards. The distal end of the outer tube  234  is formed with a holder  4  held by a hand of the operator. As shown in FIG. 1, the outer end of the holder  4  is formed with a neck portion  5  for connection to a variety of cleaning tools. The distal end of the conduit  23  within the neck portion has a joint  231 , as shown in FIG.  5 . The upper side of the neck portion  5  has a through hole  50  and a button  51  with a plurality of protrusions  511  at the bottom. An elastic element  52  is formed between the lower side of the button  51  and the upper end of the joint  231  so that the button  51  can be telescopically moved for being connected to the cleaning device as shown in FIGS. 8-10, or an extension piece  6  disposed between the holder  4  and the cleaning device as shown in FIG.  5 . 
     Referring to FIGS. 5 and 6, the extension piece  6  is formed by upper case  61  and lower case  62 . A conduit  23 ′ identical to the abovesaid conduit axially passes through between the upper and lower cases. The upper and lower cases  61  and  62  are formed with respective reduced upper case  53  and reduced lower case  54 . After matching and assembling the reduced upper case  53  and the reduced lower case  54 , the neck portion  5  is formed. The reduced upper case  53  has a through hole  50  for accommodating the button  51 . The front and rear ends of the conduit  23  are connected to the joint  231  and a sleeve  232 , respectively, which can be connected together. An end of the upper case  61  has a through hole  660  for receiving the button  51  of an attached extension piece as shown in FIG.  7 . The neck portion  5  can be connected to a cleaning tool, an iron  74  or an extension piece  6  with a connection portion  53 . In connection, the button  51  can elastically extend through the hole  60  of the connecting portion  53 , while the joint  231  is received within the sleeve  232  as shown in FIG.  7 . 
     With reference to FIG. 8, a cleaning tool  71  with a big brush is illustrated. The brush encloses around the plurality of jetting holes  8 , and the end portion thereof is formed as a portion for being connected to the connecting portion  53 . The neck portion  5  at the front end of the extension piece  6  is identical to the neck portion of the holder  4 . The distal end of the extension piece  6  is identical to the connection portion  63  of the cleaning tool. 
     With reference to FIGS. 9-11, additional embodiments of the cleaning tool and use of the cleaning tool to iron clothes are illustrated. FIG. 9 shows a jetting nozzle tube  72  which serves as a cleaning tool. The outer end of the tube has jetting holes  8  for jetting very hot vapor. Another end of the jetting nozzle tube  72  is formed as a connecting portion  63  for being connected to the neck portion  5 . 
     As shown in FIG. 10, a scraper  73  is illustrated. The end portion of the scraper  73  is formed as a connecting portion  63  for being connected to the neck portion  5 . A plurality of jetting holes  8  are arranged behind a scraping knife. 
     As shown in FIG. 11, the present invention can be connected to an iron  74  for ironing clothes. In the iron  74 , a plurality of jetting holes  8  are arranged on the bottom of the iron  74 , while the end portion is formed as a connecting portion  63  for being connected to the neck portion  5 .
