Description

Technical Field

[0001] This utility model relates to the technical field of a battery acid filling kettle, and more particularly to a battery acid filling kettle. Background Technology

[0002] A storage battery is a device that stores and releases electrical energy through a chemical reaction. Its basic working principle is to generate current by utilizing the movement of ions in the electrolyte between the positive and negative electrodes. During use, the electrolyte level in the battery may drop due to consumption or evaporation, affecting its performance and lifespan. Therefore, it is necessary to periodically add electrolyte to the battery using an acid replenishing device.

[0003] Chinese patent publication number CN219959370U discloses a universal lead-acid battery acid filling pot, comprising: an acid pot bottle with an acid outlet; an acid-leading plate inserted into the acid outlet; and a plug that fixes the acid-leading plate to the acid outlet. The acid outlet has several sets of positioning grooves of different lengths, arranged circumferentially along the inner wall of the outlet, with the length direction of the grooves parallel to the axial direction of the outlet. The acid-leading plate has a set of protrusions; in use, the protrusions cooperate with different sets of positioning grooves to change the length of the acid-leading plate extending out of the outlet. This universal lead-acid battery acid filling pot, by changing the length of the acid-leading plate extending out of the outlet, allows the pot to be used with batteries of different specifications and models, improving its versatility.

To overcome these disadvantages, this invention provides a battery acid filling jug. Utility Model Content

A connecting pipe 4 is fixedly connected to the bottom of the acid storage container 2. The other end of the connecting pipe 4 is fixedly connected to the bottom of the piston cylinder 3. A first one-way valve 401 is provided on the connecting pipe 4. The first one-way valve 401 allows fluid to pass in a direction away from the inner cavity of the acid storage container 2. An outlet pipe 5 is fixedly connected to the bottom of the piston cylinder 3. A second one-way valve 501 is provided on the outlet pipe 5. The second one-way valve 501 allows fluid to pass in a direction away from the inner cavity of the piston cylinder 3. An anti-splash mechanism is provided on the outlet pipe 5.

[0027] like Figure 1-3 As shown, a handle 101 is fixedly connected to the rear side of the support frame 1 for easy gripping.

[0028] like Figure 1-3 As shown, the piston cylinder 3 is made of transparent material. A scale 304 is fixedly connected to the outside of the piston cylinder 3. By pulling the piston rod 302 upward with the handle 303, the piston 301 is driven to slide upward along the inner wall of the piston cylinder 3, and the acid solution in the acid storage tank 2 is drawn into the piston cylinder 3 through the connecting pipe 4. The amount of suction can be controlled with the scale 304.

[0029] like Figure 1 , 3As shown, a sealing cap 202 is provided at the opening of the liquid filling pipe 201. An external thread is provided on the outside of the opening of the liquid filling pipe 201, and an internal thread is provided on the inside of the sealing cap 202 to engage with the external thread. The sealing cap 202 can be unscrewed to add acid solution to the acid storage tank 2 through the liquid filling pipe 201. A drain pipe 203 is fixedly connected to the bottom of the acid storage tank 2. A control valve 204 is provided on the drain pipe 203 to facilitate the discharge of waste liquid in the acid storage tank 2.

[0030] like Figure 3 As shown, the splash-proof mechanism includes an annular abutment plate 6, which is slidably connected to the outside of the liquid outlet pipe 5. A telescopic rod 601 is fixedly connected between the annular abutment plate 6 and the piston cylinder 3. A return spring 602 is sleeved on the outside of the telescopic rod 601. The two ends of the return spring 602 are fixedly connected to the annular abutment plate 6 and the piston cylinder 3 respectively, allowing the liquid outlet pipe 5 to extend into the acid filling port of the battery. The annular abutment plate 6 abuts against the acid filling port to prevent liquid from splashing out during the acid filling process.

The moving rod 9 and clamping plate 901 are located on both sides of the battery, allowing the liquid outlet pipe 5 to extend into the acid-adding port of the battery. The annular abutment plate 6 abuts against the acid-adding port to prevent liquid from splashing out during acid addition, reducing pollution and improving safety. Rotating the handles 701 on both sides drives the corresponding screws 7 to rotate, thereby moving the moving rods 9 and clamping plates 901 on both sides toward the battery, clamping the clamping plates 901 on both sides to the outside of the battery, thus positioning the support frame 1. To improve stability, the acid filling process eliminates the need for manual support of the container, saving manpower. By pulling the piston rod 302 upward with the handle 303, the piston 301 slides upward along the inner wall of the piston cylinder 3, drawing the acid solution in the acid storage container 2 into the piston cylinder 3 through the connecting pipe 4. The amount of acid drawn can be controlled with the scale 304. Then, by pressing the piston rod 302 downward, the piston 301 slides downward along the inner wall of the piston cylinder 3, adding the solution in the piston cylinder 3 into the acid filling port of the battery through the outlet pipe 5, thus completing the acid filling process.
