Fig. 1 is the overall schematic of one embodiment of the battery cap of the accumulator of the present invention；
Fig. 2 is the overall schematic of one embodiment of battery cap shown in FIG. 1；
Fig. 3 is the overall schematic of deflector shown in Fig. 2.
Specific implementation mode
In order to make the object, technical solution and advantage of the accumulator of the present invention be more clearly understood, below in conjunction with specific attached
Figure and specific embodiment, the present invention will be described in further detail.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of accumulator, including battery case（It is not shown）With the covering battery case
Battery cap 100, the battery cap includes the first lid 110 and the second lid 120, and first lid 110 covers institute
Battery case is stated, second lid 120 is located at the top of first lid 110, is also set up in the both sides of second lid
There is exhausting box 200.Please with further reference to Fig. 2, fixation is provided between second lid 120 and first lid 110
Deflector 130 on second lid 120；Return port 111, the deflector 130 are provided on first lid 110
Projection on first lid 110 covers the return port 111.
The first lid in the present embodiment covers battery case, when there is multiple electrolytic cells for accommodating electrolyte in battery case,
First lid could be provided as an entirety and cover entire battery case, and the second lid is also configured as an entirety, while the second lid
The area of body can be less than the area of the first lid, as long as the second lid can cover all return ports of the first lid.It stores
Battery has heat generation during use and charge and discharge, and the moisture in electrolyte is heated to become vapor, these water steam
Vapour from the space being discharged into the return port of the first lid between the first lid and the second lid, the present invention in the first lid and
Deflector is provided between second lid, therefore water vapour can continue to rise along deflector, due to the presence of deflector, delay
The rate of climb of water vapour, increases the stroke of water vapour, so that part water vapour condenses into water droplet on deflector
Battery case is flowed by return port afterwards, the loss rate of water in electrolyte is thus reduced, is experimentally confirmed and increases water conservancy diversion
The service life of accumulator averagely improves 7% after plate.
Referring to Fig. 2, the cross sectional shape of the deflector 130 in the present embodiment is parabola shaped.Due to parabolical table
Face smoother, therefore the deflector condensed water preferably of parabolic shape glides.
Referring to Fig. 3, the cross sectional shape of the deflector 130 in the present embodiment is V-arrangement.The deflector of V-arrangement facilitates manufacture
And installation.
Further, referring to Fig. 3, the deflector 130 includes left deflector 131 and right deflector 132, the left water conservancy diversion
Angle a between plate 131 and the right deflector 132 is 45 degree to 90 degree.The angle enables to the first lid and second to cover
Space between body is smaller, to reduce the volume of entire accumulator.
Referring to Fig. 2, the distance between the minimum point of the deflector 130 and first lid 110 are 5mm to 20mm.
Deflector in Fig. 2 is that upper opening is parabola shaped, therefore the minimum point of deflector can be parabolical origin.Leading in Fig. 3
Flowing plate is V-arrangement, and minimum point is as shown in the O points in Fig. 3.
Preferably, referring to Fig. 2, the projection of the minimum point of the deflector 130 on first lid 110 is located at described
In return port 111.Setting is to make the condensed water of water vapour be back in battery case rapidly in this way.
Further, leakage hole is additionally provided on the deflector 130, the leakage hole is on first lid
Projection is located in the return port.Setting is that the condensed water of the inner surface close to the second lid of deflector is made to be back to electricity in this way
In the slot of pond.
Preferably, the leakage hole is located at the lowest point of the deflector 130.
As a kind of preferable embodiment, the part surface of the close return port 111 of first lid 110 is to described
The centroclinal setting of return port.The condensed water on the surface that setting is conveniently dropped in the first lid in this way is back in battery case.
In another embodiment, be provided in the battery case it is multiple accommodate cell liquids electrolytic cells, described first
The return port being provided on lid is corresponded with the electrolytic cell, and the deflector is corresponded with the return port.Such as Fig. 1
It is shown, it is provided with 6 electrolytic cells in battery case, is provided with 6 return ports and 6 deflectors accordingly.
More preferably, the second lid in the present embodiment and deflector can be integrally formed.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be subject to claim.
