ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a humidifier, particularly to one which can send forth fragrance.
Referring to
FIG. 7
, a heretofore known humidifier comprises a housing
10
, a water tank
20
, a steam passage member
30
and a top covering
40
.
The housing
10
is provided with a water-containing hollow
101
, a pushing projection
102
, a water-detecting device
103
and an electric heating member
104
. The pushing projection
102
is arranged on the center of the hollow
101
. The hollow
101
, the water-detecting device
103
and the electric heating member
104
are arranged such that water in the hollow
101
can flow to the detecting device
103
and the electric heating member
104
.
The water tank
20
has a covering
201
screwed onto a bottom thereof. A valve
202
is fitted to the covering
201
. The water tank
20
is positioned in the housing
10
with the valve
202
contacting the top end of the pushing projection
102
. Thus, the valve
202
is opened to permit water inside the tank
20
to flow therethrough by the pushing projection
102
.
The steam passage member
30
is positioned above the electric heating member inside the housing
10
. The top covering
40
is coupled to the housing
10
with a steam outlet
401
arranged in open communication with the steam passage member
30
.
In using the humidifier, the electic heating member
104
will heat the water thereon into steam when the water-detecting device
103
detects presence of water. The steam is then ejected to the outside through the steam passage member
30
and the steam outlet
401
.
The humidifier can only humidify the surroundings without other functions i.e. the function of the humidifier is too limited to appeal to the customers.
SUMMARY
It is a main object of the present invention to provide a humidifier. It not only can humidify the air but send forth fragrance. The humidifier capable of sending forth fragrance of the present invention comprises:
a housing having a water containing hollow therein;
a water-detecting device housed in said housing;
an electrical heating member housed in said housing for heating water into steam when said detecting device detects presence of water;
a top covering coupled to said housing, said top covering having an ejecting hole for said steam to pass therethrough;
a perfume holding member coupled to and covering a part of said ejecting hole of said covering; thus, said steam is ejected through said ejecting hole to humidify the air and to heat the perfume holding member for the perfume held in the holding member to be sent forth to the air rapidly.
The ejecting hole has several radially arranged compartment walls, and two opposing curved locating plates therein. The locating plates are each connected to respective ones of the compartment walls, and each has a slot retaining a respective one of two protrusions on a bottom extension portion of said perfume holding member for said holding member to be removably coupled to said ejecting hole.
Herbs, which are fragrant or have soothing effect, can also be used in the perfume holding member in order for the humidifier to send forth the fragrance.
