Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device that allows a deodorizing device to be easily and reliably attached to the overflow pipe of a toilet flushing device.

[Summary of the invention] This invention creates multiple grooves from the tip,
The deodorizing tube at the entrance of the deodorizing device, which can be expanded and contracted in diameter, is inserted into the mounting hole provided at the top of the water tank of the water washing device, and one end of the flexible tube is forcibly fitted. The end portion is expanded in diameter and brought into pressure contact with the mounting hole, and the other end of the flexible tube is connected as an exhaust port to one end of an inverted U-shaped conduit tube having outlets on three sides.
The other end of the inverted U-shaped conduction pipe is immersed in the water tank as a water supply pipe, and when the stored water rises, the inverted U-shaped
The structure is such that water drains into the overflow pipe through the ventilation pipe of the conduit, and the flexible tube and the inverted U-shaped conduit are attached to the flushing device, thereby firmly holding the deodorizing device with its own holding force. It is something to do.

[Prior Art] A deodorizing device for a toilet that utilizes the overflow pipe of a flushing device has been provided, but no reliable means of attachment has been provided.

[Problems that the invention aims to solve] The water tanks of water washing equipment are usually made of ceramic, and unlike other equipment made of metal, they have poor dimensional accuracy and are easily damaged, so it is necessary to install the deodorizing equipment easily and reliably. Although it is surprisingly difficult, sufficient consideration has not been given to the means of attachment.

[Means for solving the problem] The present invention has a plurality of notch grooves cut from the tip of the deodorizing tube of the deodorizing device so that the diameter can be expanded and contracted freely, and one end is forced into the deodorizing tube in this end. Connect the exhaust port of the inverted U-shaped conduit pipe with a flexible tube that fits into the inverted U-shaped conduit pipe, and connect the other end of the inverted U-shaped conduit pipe, the ventilation pipe to the overflow pipe, and the water flow pipe of the inverted U-shaped conduit pipe. The above-mentioned problems are solved by having the lower end immersed in the water stored in the water tank and the upper end communicating with the exhaust port and the ventilation pipe via the inverted U-shaped conduction pipe.

[Function] In the device of the present invention, the deodorizing tube is able to expand and contract in diameter as described above, so it can be easily inserted into the mounting hole of a ceramic water tank with poor dimensional accuracy. Even if there is slack around the inserted deodorizing tube, if the flexible tube is forcibly fitted, the diameter will expand and the tube will be pressed.

Moreover, at this time, no bending stress is applied to the area around the water tank attachment hole, so there is no chance of damage.

In addition, since the inverted U-shaped conduit pipe attached to the overflow pipe is connected with a flexible pipe,
Even if there is a misalignment in the relative position of the outlet of the deodorizing device main body and the inverted U-shaped conduit pipe, the deodorizing device can be installed without any problem.

Furthermore, if the water level in the water tank rises abnormally due to a malfunction of the ball tap or the like, the water will flow into the overflow pipe via one end of the inverted U-shaped conducting pipe and the water supply pipe, and will not overflow to the outside.

[Example of the invention] Fig. 1 shows a toilet flushing device to which the invention is applied, with the water supply device such as a ball tap and the lid omitted, in which 1 is a ceramic water tank, 2 is a reservoir water tank,
3 is a water washing pipe; 4 is an overflow pipe whose lower end communicates with the water washing pipe 3 and whose upper end protrudes from the water surface of the stored water 2; Reference numeral 5 denotes a downward bowl-shaped valve body that normally closes the upper end of the flush pipe 3 and whose side end is pivoted to the overflow pipe 4. The upper end is connected to a lever 6 pivoted at the upper side wall surface of the water tank 1. The valve body 5 is opened by operating a lever 6, and the stored water 2 flows down from the flush pipe 3.

Reference numeral 8 denotes a deodorizing device attached to the side wall surface of the water tank 1. The deodorizing tube 10 of the deodorizing device 8, which is inserted through a mounting hole 9 provided at the upper part of the side wall surface of the water tank 1, has a plurality of pipes extending parallel to the axis from the tip. A notched groove 11 is cut to allow the diameter to be expanded or contracted, and a hook 12 is provided on the outer surface of the distal end, the diameter of which gradually increases toward the base end.

By reducing the diameter of the deodorizing tube 10, it can be easily inserted into the attachment hole 9. Once inserted, one end of the flexible tube 13 is forcibly fitted into the deodorizing tube 10 from the tip, and the diameter of the deodorizing tube 10 is expanded. It is crimped into the mounting hole 9, and a hook 12 prevents it from coming off.

The other end of the flexible tube 13 is connected to the exhaust port 15 of the inverted U-shaped conduit tube 14, and the lower part of the ventilation tube 16 provided in the inverted U-shaped conduit tube 14 fits into the overflow tube 4 and The lower part of the water pipe 17 provided in the inverted U-shaped conduit 14 in parallel with the trachea 16 is immersed in the stored water 2, and the vent pipe 16 and the water pipe 17 communicate below the exhaust port 15.

In the above-described water washing device, the water washing pipe 3 is constantly communicated with the deodorizing device 8 through the overflow pipe 4, the ventilation pipe 16, the exhaust port 15, the flexible pipe 13, and the deodorizing pipe 10 for deodorization.

The lower part of the water pipe 17 is normally submerged in water, so no odor leaks outside.If the water level of the stored water 2 rises abnormally due to a malfunction of the ball tap, etc. The liquid then overflows into the overflow pipe 4.

[Effects of the invention] As mentioned above, the device of the invention has a plurality of cut grooves in the deodorizing pipe and uses a flexible pipe as a part of the pipe connecting the deodorizing pipe and the overflow pipe. Therefore, the deodorizing device can be easily, safely and reliably attached to a toilet flushing device that uses a ceramic water tank that has poor dimensional accuracy and is easily damaged.
