Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for repeatedly applying a mop cleaning solution, which is used for cleaning hospital floors contaminated with bacteria, etc., in a preset amount in a mop bucket. It is a device used for taking out liquid for a certain amount of time, and more specifically, a liquid storage tank having an internal capacity that is an integral multiple of the unit extraction liquid volume or more, a metering tank having an internal capacity corresponding to the unit extraction liquid volume, and the above-mentioned liquid storage tank. A liquid take-out pipe that takes out a fixed amount of liquid filled in the metering chamber of the metering tank to a receiver such as the mop bucket described above, and a metering ring that responds to switching between the liquid take-out position and the non-liquid take-out position of the liquid take-out pipe. A state in which only the metering chamber of the tank and the liquid take-out pipe are connected in communication to take out the metered liquid, and a state in which only the liquid storage chamber of the liquid storage tank and the metering chamber are connected in communication and the metered liquid is taken out. The present invention relates to a liquid quantitative extraction device that includes a valve mechanism that can be selectively switched between filling a metering chamber with liquid and metering the liquid.

This type of liquid quantitative extraction device that has been known in the past has the following principle structure.

That is, as shown in Figure 9 A) C port) and Figure 1 O A) and (B), the liquid storage chamber (04) is located at the bottom of the liquid storage tank (04).
A) and a metering tank (Ol) are formed in a state where it is partitioned through a partition wall (07), and a valve mechanism (02) is arranged on the lateral side of this metering tank (01). The valve chamber (02B) of the valve chamber (02) is connected to the liquid storage chamber (04A) and the metering chamber (OIA) via pipes (09) and (010), respectively.
A cylindrical member (08) connected in a communicating state to the proximal end of the liquid extraction pipe (05) is fixed to the spherical movable valve body (02A) held in the liquid extraction pipe (02B). 05) around the axis of the cylindrical member (08) over a range of 20 degrees, the metering liquid is taken out as shown in Fig. 8 (a) and (b), and as shown in Fig. 9 a). It is configured to be able to switch freely between the filling metering state shown in (b).

The conventional device with the above configuration does not require pipes and connecting parts for connecting the valve mechanism and both tanks, but requires a valve mechanism with a special structure as described above. In order to prevent leakage between the pipes and the respective tanks, a large number of parts are required to quickly connect the pipes with a very high sealing effect, and in addition, there is a valve mechanism that is exposed separately and independently to both tanks. It is necessary to have a structure to protect the connecting pipes and their attachments to the tank from being damaged or deformed by contact with objects, and the number of parts as a whole is In addition, the assembly structure was complicated and the production cost was high.

In view of the above circumstances, an object of the present invention is to provide a liquid quantitative extraction device that can reduce the number of parts, use a general-purpose valve, has a simple overall structure, and is cost-effective and easy to construct.

The present invention has been devised to achieve the above object, and the feature of the liquid quantitative extraction device is that a liquid supply port with an on-off valve and a liquid drain port with an on-off valve are formed in opposing wall plate portions. A certain metering tank is located at the bottom of the liquid storage tank, with the liquid supply port being connected in communication with the liquid storage chamber of the liquid storage tank, and the liquid drain port protruding outside the liquid storage chamber of the liquid storage tank. The liquid extraction pipe connected to the liquid drain side is configured to be able to be freely switched between a liquid extraction position and a non-liquid extraction position by rotating the base end thereof, and this liquid extraction pipe In conjunction with the attitude switching, both on-off valves are set such that in the liquid withdrawal position, the liquid supply port side valve is closed and the liquid drain port side valve is open, and in the non-liquid removal position, the liquid supply port side valve is closed. In addition, an interlocking mechanism is provided that operates in reverse so that the side valve opens and the drain port side valve closes.The operation and effect of the present invention having such a characteristic configuration are as follows. .

Briefly, to summarize the above characteristic structure in other words, depending on the switching between the liquid extraction operation state and the filling metering operation state, there is a state in which the metering chamber and the liquid extraction pipe are connected in communication, and a state in which the liquid storage chamber and the liquid storage chamber are connected. A valve mechanism for switching the alternative flow path between the metering chamber and the metering chamber is provided at the drain port and the feed port, which are integrally formed with the metering tank.

The metering tank itself, which is composed of general-purpose valves such as slide valves and butterfly valves, and interlocking mechanisms such as slide rods and links that open and close these valves in a contradictory manner, also serves as the valve casing. A metering tank equipped with a valve mechanism such as this is inserted directly into the liquid storage tank or installed at the bottom of the tank, and the liquid storage chamber and the metering tank (corresponding to the valve chamber of the valve mechanism) are connected. By making the abbreviation Fi extremely short without using a special pipe, it is possible to significantly reduce the total number of component parts and to eliminate the need for a specially constructed valve mechanism.

Moreover, the valve mechanism, which is the functional heart of this type of device, is built into the metering tank and double protects against collisions with other objects, so it is a component for this purpose. No special equipment is required, and the metering tank is easy to remove and the liquid storage tank is easy to clean.

Therefore, in comparison with the conventional example described above, the overall structure is simple and manufacturing costs can be reduced, and the sealing performance and
This has resulted in the effect of improving durability in terms of mechanical strength.
