Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and more specifically relates to a combined exhaust structure in a battery maze. Background Art

[0002] The lead-acid battery used for starting a car (hereinafter referred to as the battery) is composed of a battery slot, a middle cover, an upper cover, a handle, etc. made of PP materials. The gas generated during the battery charging and discharging process usually needs to pass through the exhaust structure set in the labyrinth of the middle cover of the battery. The exhaust structure set in the existing battery labyrinth is usually a through-hole structure, which is convenient for acid addition or acid reflux, and also aggravates the overflow of acid. The exhaust hole is too low. During the battery charging process, a large number of bubbles are generated in the battery. Under the action of internal pressure, if the bubbles are not eliminated in time, the acid mixed with a large number of bubbles will overflow into the labyrinth. If the acid cannot reflux in time, when the battery is tilted at any angle, the acid is more likely to leak directly to the outside of the battery through the exhaust chamber, causing battery leakage. This structure will not only affect the service life of the battery, but also bring about the problem of sulfuric acid corrosion to the vehicle body and environmental pollution.

[0003] Therefore, there is an urgent need to improve the existing battery exhaust structure. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the utility model provides a combined exhaust structure in a battery maze, which is arranged in the maze on the middle cover of the battery, and the combined exhaust structure includes a condensation cylinder and a bubble breaking cone. The bottom of the condensation cylinder is integrally formed with a connecting ring, and a plurality of bubble breaking cones are arranged at intervals along the circumferential direction and are evenly distributed at the bottom of the connecting ring. The bottom of the condensation cylinder is open, and the top of the condensation cylinder is integrally formed with a pointed cone cap, and a plurality of exhaust holes are evenly distributed circumferentially on the side wall of the pointed cone cap. A plurality of guide plates are also evenly distributed on the inner wall of the condensation cylinder, and a narrow channel is formed between two adjacent guide plates, and the top of each narrow channel corresponds to an exhaust hole.

[0006] Preferably, the guide plate is arranged with the side away from the inner wall of the condensation cylinder pointing to the axis of the condensation cylinder, so that the bubbles can enter the narrow channels more evenly during the rising process, thereby improving the separation efficiency of gas and acid liquid.

[0007] Preferably, the connecting ring penetrates through and is sealingly connected to the middle cover of the battery, and the bubble breaking cone is inserted below the middle cover of the battery.

[0008] Preferably, the side wall of the guide plate is provided with ridges to further improve the separation efficiency of gas and acid liquid.

[0009] Preferably, a plurality of combined exhaust structures are arranged in a labyrinth on the cover of the battery.

[0010] The present invention also includes other devices or components that enable it to be used normally, all of which are conventional technical means in the field; in addition, devices or components not limited in the present invention, such as the battery middle cover, etc., all adopt conventional means in the field, and technicians in the field can select their models and installation methods according to actual usage requirements, and clearly understand how to install and control them specifically, which will not be described in detail here.

[0011] The working principle of the utility model is: during the battery charging process, due to the increase in internal pressure, a large number of bubbles of mixed acid liquid will be generated, and the bubbles will be quickly punctured under the multiple effects of the bubble breaking cone 2 at the bottom of the combined exhaust structure and the guide plate 6 and the convex ridge 8 in the condensation cylinder 1. At the same time, the guide plate and the narrow channel have both cooling and diversion effects, which can separate the gas and the acid liquid, and preferentially discharge the low-density gas from the exhaust hole at the top, so that the high-density acid flows back into the battery before reaching the maze, thereby reducing the internal pressure of the battery and maintaining the balance between the internal and external pressures of the battery.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The gas generated during the battery charging and discharging process can be separated from the acid liquid and discharged in time, thus avoiding leakage of the acid liquid and being beneficial to improving the safety and service life of the battery. BRIEF DESCRIPTION OF THE DRAWINGS
