FIGS. 1 and 2 , aconventional blower 10 generally includes abase 11 which is put on the ground and includes arecessed area 111 defined in an outer surface of thebase 11. Aninlet 112 is defined in the wall of therecessed area 111 for sucking air therethrough. Amotor assembly 12 including amotor 121 which is inserted into thechamber 113 in thebase 11 via anopen top 114 of thebase 11, and afan device 123 which is driven by themotor 121 and located above thebase 11. Themotor 121 haslugs 122 which are fixed torecesses 115 defined in a top of thebase 11. Ahood 13 is mounted to the top of thebase 11 and includes anoutlet 131 such that air generated by thefan device 123 is send from theoutlet 131. Nevertheless, the position of theinlet 112 is close to the ground so that dust and peddles are sucked into the blower and could damage the parts of thefan device 123 and themotor 121. Furthermore, the distance between themotor 121 and thebase 11 is so small that heat generated by themotor 121 is difficult to escape so that thebase 11 could be burned. - Another
conventional blower 20 is shown inFIG. 3 and includes abase 21 with achamber 24 defined therein so that themotor 22 is received in thechamber 24. A plurality ofinward protrusions 25 extend inward from an inner periphery of thechamber 24 andconnection plates 26 on themotor 22 are fixed to theprotrusions 25 to position themotor 22 in thechamber 24. Ahood 23 is connected to an end of thebase 21 and includes anoutlet 27 to send the air generated by the fan device (not shown) driven by themotor 22. It is noted that themotor 22 is hanged by theconnection plates 26 in thechamber 24, so that themotor 22 tends to drop due to gravity and theconnection plates 26 are easily deformed by any impact during transportation. Cracks may be found at the area of thebase 22 where theconnection plates 26 are connected if the impact is severe. - The present invention intends to provide a blower wherein the base includes a connection portion in the chamber and the motor is secured on the connection portion.
- The present invention relates to blower which comprises a base with a passage defined therethrough which defines two openings in two ends of the base. A connection portion is located in the passage and a plurality of inward protrusions extend from an inner periphery of the passage. A motor assembly including a motor which is received in the passage and includes a positioning frame fixed on the connection portion, and a fan device which is driven by the motor. The motor has a plurality of connection plates connected between the motor and the inward protrusions. A hood is connected to an end of the base and encloses one of the two openings in the two ends of the base. An outlet is defined in the hood so that air flow generated by the fan device is sent therefrom.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
-
FIG. 1 is an exploded view to show a conventional blower; -
FIG. 2 is a side view to show the conventional blower inFIG. 1 ; -
FIG. 3 shows another conventional blower; -
FIG. 4 is a perspective view to show the blower of the present invention; -
FIG. 5 is an exploded view to show the blower of the present invention; -
FIG. 6 is an end cross sectional view to show the motor fixed on the connection portion, and -
FIG. 7 shows two blowers of the present invention are overlapped with each other. - Referring to FIGS. 4 to 6, the blower of the present invention comprises a
base 30 with apassage 31 defined therethrough so as to define two openings in two ends of thebase 30. Aconnection portion 34 is located in thepassage 31 and agroove 341 is defined in a top of theconnection portion 34. A plurality ofinward protrusions 32 extend from an inner periphery of thepassage 31. - A
motor assembly 40 includes amotor 41 and afan device 42 which is driven by themotor 41. Themotor 41 is received in thepassage 31 and includes apositioning frame 411 which is composed of tow elongated portions which are fixed on theconnection portion 34 and located across thegroove 341 so that a gap is defined between an inside of thegroove 341 and themotor 41. The gap allows air flow passing through the gap to bring heat from themotor 41. A plurality ofconnection plates 412 are connected between themotor 41 and theinward protrusions 32. By theconnection plates 412 and thepositioning frame 411, themotor 41 is well positioned in thebase 30. - A
hood 50 is connected to an end of thebase 30 and covers one of the two openings in the two ends of thebase 30. Thefan device 42 is received in the interior of thehood 50 so that air flow generated by thefan device 42 is sent from anoutlet 51 of thehood 50. Afilter cap 33 with afilter net 331 is fixed to the other opening of thebase 30 so as to filter the air intakes from the opening. - The
base 30 further includes twolegs 300 extend from an underside of each of the two ends of thebase 30 and a space is defined between thelegs 300 on the two ends of thebase 30 and the underside of thebase 30. This ensures that an enough space is provided between themotor 41 and the floor so that heat from themotor 41 is not trapped to burn thebase 30. Further referring toFIG. 7 , arecess 35 is defined between the twolegs 300 on each one of the two ends of thebase 30 and twoengaging portions 301 extend from a top on two ends of thebase 30. The twoengaging portions 301 are sized to be engaged with therecesses 35 when overlapping twobases 30 with each other to save storing space. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
