Where being described in detail the technical characterstic of the utility model, hereby for following embodiment and coordinate description of the drawings such as
Afterwards, wherein：
As shown in Figure 1 to Figure 3, the utility model first embodiment provided it is a kind of to motor drive shaft have waterproof work(
The drain motor 10 of energy, is mainly made of a casing 11, a motor 21, a Discharging blades 31 and a water deflector cover 41, wherein：
The casing 11, bottom have a water drain cavity 13, which has first perforation 15 for being located at top.
The motor 21, set on the casing 11 and above the water drain cavity 13, which has one to be located at bottom
Second perforation 23 and a drive shaft 25, the bottom end of the drive shaft 25 are pierced by by second perforation 23.
The Discharging blades 31, in the water drain cavity 13, which has a mandrel 33, the top of the mandrel 33
End is exposed to upwards outside the water drain cavity 13, and the bottom end of the drive shaft 25 is inserted in the top of the mandrel 33, the top of the mandrel 33
End defines with a first end face 331 and downwards a preset distance by the first end face 331 along the body portion week of the mandrel 33
First fitting section 333.
The water deflector cover 41, the one cyclic annular fin 43 of top side extension of the water deflector cover 41 and with one downward opening the
One sleeve 45, has one first bottom surface 46 and one first peripheral wall 47 in first sleeve 45, which has one the
Three perforation 461, the water deflector cover 41 wear third perforation 461 by the drive shaft 25 and are located at first perforation 15 and the mandrel 33
Between, and first sleeve 45 is sleeved on the top of the mandrel 33, wherein, which is resisted against the first end face first
End face 331, and first peripheral wall 47 is tightly attached to the first fitting section 333.Thereby, the waterproof drive shaft 25 along the motor 21
And enter the motor 21.
It follows that by above-mentioned structure, drive shaft 25 of the utility model waterproof along the motor 21 can be enable
And enter the motor 21.
In this present embodiment, agent 51 is sticked with more a waterproof, which sticks 51 cloth of agent and impose on first peripheral wall 47 with being somebody's turn to do
Between first fitting section 333, it is intended that increase by first peripheral wall 47 first is bonded adaptation between section 333 with this, more
Add and promote the effect that waterproof enters the motor 21 along the drive shaft 25 of the motor 21.In it in embodiment, which sticks
Agent 51 can also increase cloth and impose between first bottom surface 46 and the first end face 331 (figure does not regard) or cloth be coordinated to impose on other
First sleeve 45 of different structure and the suit place (not shown) of 33 one end of mandrel, therefore, which sticks the reality of agent 51
Kenel is applied, should be not only limited with the present embodiment.Then, if first sleeve 45 has been sleeved on the adaptation on 33 top of mandrel
Enough, then it does not need to the charity waterproof and sticks agent 51, therefore, it is not necessity member when the utility model is implemented which, which sticks agent 51,
Part.
The structure kenel of the utility model first embodiment is explained above, continues illustrate that the utility model first is real below
Apply the use state of example.
It please refers to as shown in Figure 1 to Figure 3, for the utility model when draining, the Discharging blades 31 are by the driving of the motor 21
Axis 25 drives and rotates, come assist to discharge the water in the water drain cavity 13 by a drainpipe (due to water adverse current situation with
And drainpipe is all that known this field those skilled in the art is noted, and therefore, is not indicated still further in this case attached drawing).
When the utility model stops draining, which shuts down and stops the drive shaft 25 to the draining leaf
The driving of piece 31 at this point, the still undischarged water can be back to the water drain cavity 13 in the drainpipe, and is originally present in the row
The water in water chamber 13 upwardly through first perforation 15 and situation about sputtering can occur towards the motor 21, at this point, due to this
The first end face 331 is tightly attached in first bottom surface 46, and first peripheral wall 47 is tightly attached to the first fitting section 333, therefore, towards the horse
Up to the water of 21 sputterings, it is difficult to enter along the axle body of the drive shaft 25 between first sleeve 45 and 33 top of mandrel
Into the motor 21, and the water that remaining is sputtered towards the motor 21, it can be blocked by the ring-type fin 43.It follows that this reality
With novel in addition to the ring-type fin 43 can block the water into other than the motor 21, due to first bottom surface 46 by be butted on this
End face 331, and first peripheral wall 47 is tightly attached to the first fitting section 333, therefore, the utility model can reach waterproof along this
The drive shaft 25 of motor 21 and the effect for entering the motor 21.
Accordingly, the drain motor 10 to motor drive shaft with water-proof function provided by the utility model, can effectively prevent
Water enters the motor 21 along the drive shaft 25 of the motor 21.
Then, referring again to Fig. 4, the utility model second embodiment provided it is a kind of to motor drive shaft have waterproof
The drain motor 10 ' of function is mainly generally same as preceding first embodiment, the difference is that：
Upward one second sleeve 47 ' of projection in top of the water deflector cover 41 ', 47 ' the fitting drive shaft 25 ' of the second sleeve
Part axle body.Therefore, when the drive shaft 25 ' of the water towards the top of the water deflector cover 41 ', due to the second sleeve 47 '
The part axle body of the fitting drive shaft 25 ', thus the drive shaft 25 ' can by the second sleeve 47 ' by the pool every will not attach
To the drive shaft 25 ', thereby, there is the effect that waterproof enters the motor 21 ' along the drive shaft 25 ' of the motor 21 '.
The utility model second embodiment is generally same as preceding first embodiment in structure and the effect of reaching, holds not
It gives and repeating again.
Come again, please refer to Fig. 5 and Fig. 6, what the utility model 3rd embodiment was provided a kind of has motor drive shaft
The drain motor 10 " of water-proof function is mainly generally same as preceding second embodiment, the difference is that：
33 " the top of mandrel has more protruded out a sub- mandrel 61 ", and the drive shaft 25 " is across the sub- mandrel 61 ", the sub- mandrel
61 " top has a second end face 611 " and is determined downwards along the body portion week of the sub- mandrel 61 " by the second end face 611 "
Second fitting section 613 " of an adopted preset distance；The center of first bottom surface 46 " is more recessed with a groove 48 ", the groove 48 "
Bore is less than the bore of first sleeve 45 ", which is sleeved on the sub- mandrel 33 ", wherein, which has one the
Two bottom surfaces 481 " and one second peripheral wall 483 ", second bottom surface 481 " is by being butted on the second end face 611 ", and second peripheral wall
483 " are tightly attached to the second fitting section 613 ".It follows that since second bottom surface 481 " is by being butted on the second end face 611 ", and
Second peripheral wall 483 " be tightly attached to this second fitting section 613 ", thereby, have waterproof along the drive shaft 25 " of the motor 21 " and
Into the effect of the motor 21 ".
It can be seen from the above, since second bottom surface 481 " is by being butted on the second end face 611 ", and second peripheral wall 483 " is tight
It is affixed on the technical characteristic of the second fitting section 613 ", the drive shaft 25 " that can make the utility model that there is waterproof along the motor 21 "
And enter the effect of the motor 21 ".
The utility model 3rd embodiment is generally same as preceding second embodiment in structure and the effect of reaching, holds not
It gives and repeating again.
Certainly, the utility model can also have other various embodiments, without departing substantially from the spirit of the present invention and its essence
In the case of, those skilled in the art work as can make various corresponding changes and deformation, but these according to the utility model
It is corresponding to change and deform the scope of the claims that all belong to appended by the utility model.
