Description

 The invention relates to a means of filling liquids in vessels to a certain level and can be used to top up with distilled water when servicing batteries.

Known dispensers for bottling liquids with measuring devices, upper and lower locking elements, allowing the filling of certain doses [1]
The disadvantage of these devices is the inability to restore these doses in the vessels if the liquid has evaporated or leakage has occurred.

 The closest in technical essence to the claimed invention (prototype) should be considered a funnel-dispenser, which ensures the delivery of the required doses of liquid to the vessel and stops the flow of liquid when the limit is reached [2] The funnel-dispenser contains a receiving bowl with a drain pipe, inside which the rod is mounted made in one piece with the valve and the float. During use, the liquid is poured into the funnel, the dispenser is inserted into the vessel, and then the valve opens by pressing on the stem. When the vessel is full, when the liquid reaches the neck, the float rises and closes the valve through the stem. The dispenser allows you to within a small range to change the level of liquid filling due to the adjustment rings.

 However, the dispenser is not adapted to establish the required level of liquid in the vessel, measured from the bottom. And even if it can be used in some cases for this purpose, this process will require special calculations and additional devices to measure the real depth of the vessel. The use of the prototype will be particularly difficult if it is necessary to establish a given level of liquid in vessels with different distances from the necks to the bottom.

 The purpose of the invention, giving the dispenser the ability to set the liquid level in the vessels, set from the bottom.

 The goal is achieved by the fact that the dispenser is equipped with a rod with a thrust bearing, which, when resting against the bottom of the vessel, slides into the receiving bowl and opens the upper valve, allowing liquid from the funnel (bowl) to flow into the vessel until the float with the tubular shaft and shutoff valve rises with the water level in the vessel, it will not block the bottom of the outlet of the bowl.

 Comparative analysis with the prototype allows us to conclude that the inventive funnel-dispenser has significant differences and meets the criterion of novelty.

 The drawing shows a funnel-dispenser in the process of filling the liquid into the tank to the desired level.

 The metering funnel consists of a receiving bowl with a drain pipe 1, a rod 2 with a thrust bearing 3 and an upper valve 4, a float 5 with a tubular stand 6 and a shut-off valve 7.

 The sequence of actions is as follows. Liquid is poured into the receiving bowl. In this case, the liquid remains in the bowl, since under the action of the spring 8, the upper valve 4 is closed.

 To spill liquid, it is necessary to support thrust bearing 3 in the bottom (see drawing) of the vessel. In this case, valve 4 opens and fluid begins to flow through the drain pipe. In the process of increasing the liquid level, the float 5 with the tubular stand 6 slides along the rod 2 and, when the required liquid level in the vessel is reached, the shut-off valve 7 closes the outlet. The flow of fluid from the receiving bowl stops.

 The height of the liquid level can be adjusted by the length of the tubular stand in various ways: by changing them or sliding (unscrewing) when the design is complicated.

 Thus, the proposed tool makes it possible to fill (top up) liquids into the vessels at the level required from the bottom or from any other partition, regardless of the height of the vessel itself. In practice, such a need arises sharply when servicing all types of modern starting batteries, in which the electrolyte level should be 10-15 mm from the safety plate. Lowering the electrolyte level in the batteries due to the evaporation of water leads to sulfation of the plates, increasing the level to electrolyte spraying, enhanced self-discharge, and corrosion of the terminals. The metering funnel will provide tangible help to both professionals and amateur drivers when servicing rechargeable batteries, since each battery has 4 to 10 separate cans (vessels) that require strict electrolyte installation. Refueling time of one battery in comparison with manual refueling according to preliminary calculations can be reduced by 5-10 minutes with guaranteed quality. The dispenser is simple in industrial production and can be offered for enterprises producing accessories for battery maintenance.
