Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain trap, and more particularly to a drain trap that is preferably used in a dental care device.

[0002]

2. Description of the Related Art Conventionally, drain traps have been arranged for the purpose of preventing backflow of odors in the middle of drain pipes of medical and dental medical equipment. FIG. 5 shows a vertical sectional view of a drain trap having a conventional structure, and FIG. 6 shows an exploded view of its component parts. The drain trap of the dental treatment device is installed in the drainage channel of the dental treatment device in order to prevent backflow of odor during dental treatment and remove dirt in the drainage. The drain trap of the conventional structure has a pipeline inlet 1a vertically provided at an upper portion thereof, a pipeline outlet 1b horizontally provided, and a cap 1 at a lower outer peripheral portion thereof.
2, a cylindrical trap body 1 formed with an external thread 1c for screwing, a filter 3 made of a cylindrical wire mesh and a handle 3a protruding from the lower end, a circular packing 4 having a central hole, and the trap The filter body 3 and the packing 4 are housed in the main body 1 and can be tightened.
The trap body 1 is always fixed to the drainage channel. Wastewater flows from the pipe inlet 1a into the trap body 1 and collects,
It passes through the filter 3 and is discharged from the conduit outlet 1b.
The packing 4 is for preventing leakage from the cap 12. It is necessary to remove the cap 12 in order to regularly clean the dirt accumulated in the trap body 1.
Since the drainage collected inside flows out, a bucket for receiving the drainage must be prepared, and when the cap 12 is removed, the dirty drainage is caught and becomes unsanitary.

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems, and a cap body formed in a cup shape for storing water is attached to the trap body, and the trap body flows out from the trap body. The drain trap that allows the filter and packing to be taken out without the need for a bucket when cleaning and without removing the cap body from the trap body It is the one we are trying to provide. That is, the present invention is a drain trap characterized in that a cap body, which is formed in a cup shape for storing water, is attached to a lower portion of the trap body. Further, it is preferable that the drain trap has a cap portion that can be screwed on the trap body and is erected at the center of the cap body formed in a cup shape. Further, the drain trap of the present invention has a U-shaped groove for drainage provided on the side surface of the cap portion, and when removed from the trap body, drainage collected in the trap body is collected through the U-shaped groove. It is preferable that the structure is such that it can be gradually discharged to a portion. By disposing a drainage U-shaped groove on the side surface of the cap portion of the cap body, when it is removed from the trap body, the drainage collected in the trap body is gradually drained to the water reservoir through the U-shaped groove. It is possible to eliminate the fear that the accumulated drainage will be scattered outside the cap body. The drain trap of the present invention is particularly suitable for medical treatment
It is suitable for use in dental treatment equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a drainage trap in a dental treatment apparatus of the present invention will be described below with reference to the drawings. 1 is a longitudinal sectional view of an embodiment of the drain trap of the present invention, FIG. 2 is an exploded view of the components of the drain trap of FIG. 1, FIG. 3 is a vertical sectional view of the drain trap of FIG. Figure 4
FIG. 8 is a vertical sectional view of another embodiment of the drain trap. In the figure,
1 is a trap body, 2 is a cap body, 2a is a cap portion, 2d is a U-shaped groove, 3 is a filter, 4 is packing, 5
Is a water reservoir, 6 is drainage, and 7 is a cap body. In the drain trap of the present invention, the trap body 1, the filter 3 and the packing 4 have the conventional structure, but in the cap body 2 attached to the trap body 1, the cap portion 2a is erected at the center of the cup-shaped cylindrical container. Then, the trap body 1 can be screwed into the trap body 1, and the water reservoir 5 is formed in the surrounding cup-shaped container so that the drainage flowing out when it is removed from the trap body 1 is collected in the water reservoir 5 without spilling out. I am trying. Therefore, the capacity of the water reservoir 5 needs to be sufficient to receive the drainage 6 accumulated in the trap body 1. Reference numeral 2b is a female thread portion of the cap portion 2a screwed to the male thread portion 1c of the trap body 1. Further, the concave portion 2e provided in the cap portion 2a is provided with a handle 3 of the filter 3.
It is provided so as not to hit a, and needless to say, the filter 3 having a structure in which the handle 3a does not project.

Further, a U-shaped groove 2d for drainage is formed on the side surface of the cap portion 2a in a slotted manner. When the cap portion 2a is removed from the trap body 1, as shown in FIG. Since the drainage 6 accumulated in the U-shaped groove 2d can be gradually discharged to the water reservoir 5, the trap body 1 is not covered with the cap 2a when the U-shaped groove 2d is not provided.
At the moment when the cap comes off, the drainage 6 that has accumulated is discharged all at once, eliminating the fear of scattering outside the cap body 2.
Further, a straight guide portion 2c is provided above the female screw portion 2b of the cap portion 2a, and when the cap body 2 is attached, it serves as a guide for the male screw portion 1c and the female screw portion 2b, so that the cap body 2 can be easily attached and tilted to be attached. Since this is not done, the cap body 2 can be completely screwed in and installed.

In another embodiment of the drain trap shown in FIG. 4, the cap body 7 has a structure in which the cap portion 7a is provided on the pillar 7c at the center of the cap body 7, and the cap body 2 of the preceding example is used. Like the above, the drainage is prevented from flowing out and can be attached to the trap body 1. 7b
A female screw, 7d is a water reservoir. Further, the cap portion 7a may be provided with a U-shaped groove 2d for gradually discharging the drainage as in the previous example, or may be provided with a guide portion 2c for facilitating attachment.

[0007]

The drain trap of the present invention prevents the drainage from flowing out of the cap body by forming the cap body in the shape of a cup for storing water. You don't have to worry about getting your hands flooded with a bucket, etc. Therefore, the cap body according to the present invention can be removed from the trap body at any time for easy cleaning.
