Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flow rate regulating device for dripping liquid at a constant flow rate, such as in a floor cleaning machine or chemical spraying machine.

Conventionally, there are floor cleaning machines that wash carpets, tiles, and other floor surfaces by dripping detergent solution and wetting the floor surface with a rotating brush or mop, and machines that spray liquid chemicals on the ground and floors by hand. Are known.

In these floor cleaning machines and spraying machines, detergent liquid or chemicals are usually put into a detergent chamber or a chemical tank, and the cleaning and spraying is performed while adjusting the flow rate or dripping amount using a valve mechanism.

However, with a normal valve mechanism, if the amount of detergent liquid (hereinafter including chemicals) in the detergent chamber (hereinafter also includes chemical chamber) is constant, that is, the liquid level is approximately the same, the flow rate is approximately constant, but if the liquid level is As the flow descends, the flow rate decreases, and the valves must be adjusted frequently, which has the disadvantage of interfering with cleaning and spraying operations.

The object of the present invention is to eliminate such drawbacks and to provide a flow rate regulating device in which the flow rate of the detergent solution can be kept almost constant by keeping the position of the valve constant even if the amount of detergent solution or chemicals decreases. That is.

In order to achieve this objective distantly, the present invention provides a flow control chamber in the detergent chamber, has an almost vertical inner wall and an inclined outer wall, and has one or more corrugated convex sections with a similar cross-sectional shape. A part is provided on the floor of the detergent chamber, and the detergent liquid is swung back and forth by the back and forth movement of the washing machine, so that the flow rate adjustment chamber is always full, the liquid level is kept constant, and the flow rate is constant.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure and effects of the present invention will be described below with reference to embodiments shown in the accompanying drawings.

Note that although a cleaning machine will be explained below, the same applies to a chemical sprayer.

Reference numeral 1 in the figure indicates the main body of the floor cleaning machine.

A bottom member 2 is welded to the main body 1 by high frequency, etc.
A detergent chamber 11 is configured surrounded by side walls.

As a washing machine, the detergent liquid injected into the detergent chamber 11 is adjusted by the valve mechanism 3 and the valve seat 26 that constitute the valve member, and is sent to the rotary mop or the rotary brush 4 through a large number of injection holes provided in the block 27. Drop and clean the floor surface.

Although the attached drawing shows that the waste liquid is collected by the scraper 41 and recovered from the inlet of the lid 42 of the waste liquid chamber 43, the structure of the rotating brush or rotary mop 4 is not important, and the scraper 41 and the waste liquid chamber 43 are It doesn't have to be there.

5 indicates a handle for operating the main body.

On the upper surface of the bottom member 2, that is, in the detergent chamber 11, a horizontally elongated flow rate adjustment chamber 21 is provided in a direction perpendicular to the direction of movement of the washer.

The flow rate adjustment chamber 21 has a corrugated side wall 22 that is perpendicular to the direction of movement.
The inner walls of and 23 are substantially vertical, and the outer walls are sloped.

This is because when the detergent liquid swings back and forth during the cleaning process and has a wave-like motion, it tends to cross over the slope and accumulate in the flow rate adjustment chamber.Conversely, the detergent liquid that has accumulated in the flow rate adjustment chamber is prevented from flowing out due to the back and forth rocking. It's for a reason.

Furthermore, in this embodiment, a convex portion 25 with a wavy cross section is provided on the bottom surface of the detergent chamber to partition the detergent chamber, and the wall surface near the flow rate adjustment chamber is made almost vertical, and the other surface is inclined so that the detergent solution is oscillated. When the detergent liquid moves in a wave pattern due to the movement, the detergent liquid travels along the slope and easily flows to the opposite side of the curved part (from A to B in Figure 1).
, and is constructed to prevent backflow.

From the state where the detergent chamber 11 is filled with detergent solution or water to the level shown in FIG.

When the detergent liquid decreases and the liquid level falls to the horizontal position X, the detergent liquid in B and C jumps over the corrugated side walls 23 and 22 and enters the flow rate adjustment chamber 21 due to the back and forth movement of the washer during the cleaning operation. When the liquid level is further lowered below the top of the convex portion 25, the detergent liquid at position A moves to B, and further enters the flow rate adjustment chamber 21 from position B, and despite the flow of the detergent liquid, First, keep the flow control chamber always full.

As a result, the liquid level in the control chamber is always maintained at approximately the height of the side wall, so even though the detergent liquid decreases overall, the liquid volume and level in the control chamber are kept constant, and therefore the flow rate is can always be kept constant.

As described above, according to the present invention, a constant flow rate can be ensured by the back-and-forth movement of the cleaning machine or chemical sprayer despite the decrease in detergent liquid or chemical liquid, so that the valve mechanism can be used during cleaning or chemical spraying work. There is no need to adjust the flow rate, and work can be performed stably until the liquid runs out.

Note that the present invention is not limited to the embodiment shown in the drawings, and may be a manual or electric cleaning machine or chemical sprayer as long as the main body is swung back and forth. It can also be used for
