Description
BACKGROUND OF THE INVENTION
The present invention is related to a safety protective cover of a blender. The protective cover is transparent and integrally molded. The protective cover is associated with the blending container to achieve a protection effect.
FIG. 9
shows a conventional food blender used to blend flour mash, etc. The food blender includes a bed
7
having a forward extending substantially semicircular support arm
71
. A blending container
8
is placed on the support arm
71
. The head section
72
of the blender, which is disposed on upper side of the bed
7
has a rotary shaft
73
right above the blending container. A blending bar
74
is mounted on the rotary shaft for stirring and blending the materials contained in the blending container.
In blending operation, the materials often splash to contaminate the blender and the environment. Moreover, the blender is rotated at very high rotational speed and great torque. This is dangerous to a user.
A protective mesh
9
is mounted on the head section to solve this problem. The protective mesh
9
is conic and positioned around the rotary shaft. When the blending container ascends to make the blending bar extend into the blending container, the protective mesh shields the upper side of the blending container to prevent a user from incautiously touching the blending bar in operation. However, such protective mesh cannot avoid splash of the materials. On the contrary, the protective mesh will be contaminated by the remainders which are hard to be cleared up. Under such circumstance, the user must detach the protective mesh for washing. This is quite inconvenient to a user so that the user often simply wipes the protective mesh without taking off the same. As a result, much dirt will accumulate in the meshes of the protective mesh. It is known that a certain amount of water is often added into the materials to modulate the thickness of the blended materials. A user often directly adds the water through the protective mesh into the blending container during operation. Under such circumstance, the water will entrain the dirt in the protective mesh to contaminate the blended materials.
Furthermore, only when the blending container ascends, the protective mesh can provide a protection function. When the blending container is descended, the protective mesh cannot shield the blending container. Normally the blender should be in an off state when the container is descended. However, when the user's hand extends into the blending container and the blender is mis-activated, the user may still get hurt.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a safety protective cover of a blender. The protective cover is associated with the blending container and can be easily detached therefrom. Only after the blending container is ascended and located, the blender is activated so that the safety in use can be ensured.
It is a further object of the present invention to provide the above safety protective cover which is made by integral molding to lower manufacturing cost. In addition, the protective cover serves to prevent the blended materials from splashing out.
The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Please refer to
FIGS. 1
to
8
. The blender of the present invention includes a bed
10
and a support arm
11
extending from front side of the bed
10
. A crank
14
is disposed on a lateral side of the bed for moving the support arm up and down. A U-shaped blending container
20
can be placed on the support arm
11
. The top edge of the blending container is formed with a flange
21
. A head section
101
of the blender is disposed on upper side of the bed
10
. The head section
101
has a rotary shaft
12
right above the blending container. A blending device
5
is mounted on the rotary shaft
12
.
A protective cover
4
is connected with upper edge of the blending container
20
. Referring to
FIG. 2
, the protective cover is integrally made of a transparent material. The bottom of the protective cover at least covers the upper opening
201
of blending container. The bottom side of the circumference of the protective cover abuts against the top side of the flange
21
of the blending container. An annular section
41
protrudes from the bottom of the protective cover and extends along the inner face of the wall of the blending container. Two handle sections
42
transversely protrude from two lateral sides of the bottom of the protective cover. A latch member
3
is disposed under the bottom side of each handle section
42
. The latch members
3
are latched with lower side of the flange of the blending container to firmly associate the protective cover with the blending container as shown in
FIGS. 6 and 8
.
The latch member has a fixing section
31
including two symmetrical lugs
311
. Each lug has a fixing hole
312
. Two projecting posts
421
are disposed in the handle section corresponding to the lugs for a screw
422
to lock the latch member.
The latch member has a plate-shaped latch hook
32
downward extending between the two lugs. The latch hook is bent toward the center of the protective cover to form a stop section
321
for stopping lower side of the flange of the blending container. The stop section is further reversely bent and extended to form a press section
322
for a user to press.
As shown in
FIG. 5
, the circumference of the protective cover is formed with a notch
44
. The top side of the flange of the blending container is formed with a projecting section
211
. The projecting section
211
can be engaged in the notch
44
to locate the protective cover.
The top of the protective cover is formed with an opening
45
at the axis of the rotary shaft
12
. The opening
45
linearly extends to the circumference of the protective cover to form a split
451
. The width of the opening is at least equal to the diameter of the rotary shaft.
In addition, a through hole
46
is formed on the protective cover, whereby a user can add water through the through hole into the blending container. Moreover, a touch board
47
projects from the protective cover. A switch
13
is disposed on lower side of the head section
101
above the touch board. When the blending container is ascended, referring to
FIG. 4
, the touch board touches the switch to turn on the blender.
In use, the blender container is placed on the support arm. The protective cover is overlaid on the blending container with the shaft of the blending device passing through the split
451
of the protective cover. Referring to
FIGS. 5
to
8
, a user respectively presses the press sections
322
of the two latch members with two hands. At this time, the two lugs of the fixing sections of the latch members are locked and the latch hooks
32
are entirely flexed and deformed to downward turn open the stop sections
321
. Under such circumstance, when the user releases the press sections of the latch members, the two latch members will resiliently restore to make the stop sections abut against the flange of the blending container. Accordingly, the protective cover is firmly associated with the blending container. By means of engaging the projecting section in the notch of the protective cover, the protective cover is located with the opening aligned with lower side of the head section.
Referring to
FIGS. 3 and 4
, when a user cranks the crank
14
to lift the support arm, the top side of the protective cover shields the gap between the upper side of the blending container and the head section and touches the switch
13
. Therefore, the blending container is ensured to locate in a ready position and in a safe state and then the blender is activated. By means of the protective cover, the blended materials are obstructed from splashing out. The use can directly see the blending state through the protective cover.
The protective cover is simply associated with the blending container by means of hooking the latch members with the flange. Therefore, after the blending operation is finished and it is desired to take off the protective cover for washing, the user only needs to bias the latch members on two sides of the protective cover with two hands to directly taking off the protective cover from the blending container. Accordingly, no other component needs to be detached and it is convenient to take off and wash the protective cover. The protective cover serves to protect a user from incautiously touching the blending bar and getting hurt. Moreover, the manufacturing cost of the protective cover is lower than the conventional protective mesh and the appearance of the protective cover is more beautiful than the protective mesh.
When the support arm is descended, the switch is free from the touch of the touch board. At this time, the blender is turned off and will not be unexpectedly activated due to incaution. All the blending operation is performed only when the protective cover is mounted and the blending container is truly located. Therefore, the safety of the user can be ensured.
The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
