Description of the drawings
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 schematic top plan view of taper 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
Taper deflector 130 on second lid 120；Return port 111, the water conservancy diversion are provided on first lid 110
Projection of the plate 130 on first lid 110 covers the return port 111.The deflector is integrally tapered, the taper
The vertex O of deflector is close to first lid.
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
Taper deflector is provided between second lid, therefore water vapour can be along the surface flow of taper deflector, since taper is led
The presence of flowing plate has delayed the rate of climb of water vapour, increases the stroke of water vapour, so that part water vapour is in taper
It is condensed on the surface of deflector and battery case is flowed by return port after water droplet, thus reduce the loss speed of water in electrolyte
Rate, the service life for being experimentally confirmed accumulator after increasing deflector averagely improve 7%.
Further, it is in coniform that the present embodiment, which limits taper deflector integrally, and setting is more convenient in this way condenses water flowing.
Referring to Fig. 2, the distance between the vertex of the taper deflector 130 and first lid 110 be 5mm extremely
20mm.It should be noted that the vertex of taper deflector can be located at the top of the first lid in the present embodiment, can also be located at
The lower section of first lid.
In one of the embodiments, referring to Fig. 2, the vertex of the taper deflector 130 is located at first lid 110
Between second lid 120.At this point, taper deflector is integrally respectively positioned on the top of the first lid 110.
In another embodiment, the vertex of the taper deflector 130 is located at the inside of the battery case, and the cone
There are prepsetting gaps between shape deflector 130 and the liquid level of the battery case.At this point, taper baffle portion is located at the first lid
Top, the vertex of another part especially taper deflector is located at the lower section of the first lid.Setting can preferably be led in this way
Flowing water steam.The vertex of taper deflector cannot contact the liquid level of electrolyte in the present embodiment.
When the lower section of the first lid of the vertex of taper deflector（I.e. the vertex of taper deflector is located in battery case）, institute
State between taper deflector and the return port that there are prepsetting gaps.That is taper deflector is not contacted with return port.Compared with
Excellent, the diameter in section of the taper deflector on first lid is 1 with the diameter ratio of the return port：1.2
~1.8.
Further, projection of the vertex of the taper deflector 130 on first lid 110 is located at the reflux
Kong Zhong.
Further, leakage hole 131 is additionally provided on the taper deflector 130, the leakage hole 131 is described
Projection on one lid 110 is located in the return port.Setting is to make the inner surface close to the second lid of deflector in this way
Condensed water is back in battery case.
Preferably, referring to Fig. 3, the leakage hole is located at the vertex 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 taper deflector is corresponded with the return port.
As shown in Figure 1, being provided with 6 electrolytic cells in battery case, it is provided with 6 return ports and 6 taper deflectors accordingly.
More preferably, the second lid in the present embodiment and taper 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.
