Abstract

The utility model relates to an odour seal with u-shaped trap used in daily life for hand-washing basins and bathtubs. The utility model is characterized in that an odour pipe 2 is positioned between the water inlet pipe of an S pipe 1 and the center pipe of the S pipe 1. Both ends of the odour pipe 2 are sealed. The part of the odour pipe 2 near the lower end is communicated with the part of the water inlet pipe of the S pipe 1 near the lower end by a hope. The upper end of the odour pipe 2 is communicated with the upper end of the center pipe of the S pipe 1 by a hole. The utility model can block the air communication between the sewer and the pipes of the water tank and prevent the mildewed, rot, decaying odour, mosquitoes and bacterium from rising. The odour seal with u-shaped trap has simple structure and low cost.

Description

Odour seal with U-shaped trap

The utility model relates to the trapping pipe of daily life with water containers such as wash basin, bathtubs.

At present, the trapping pipe that is used for the water container such as wash basin, bathtub of daily life comprises S type and P type, because siphonage, in the trapping pipe, seal up for safekeeping after the draining with regard to anhydrous, cause the rancid gas of sewer and mosquito, bacterium just can rise to the water space of wash basin, bathtub along pipe, even be diffused in the room, caused indoor pollution, influenced the healthy of people.

The purpose of this utility model provides a kind of trapping pipe of water container, and it can not only draining and has blocked sewer and communicate with air between the water container.

Technical solution of the present utility model is finished like this, promptly on the basis of S type trapping pipe between water containers such as existing wash basin, bathtub and the blow-off pipe and screw plug, particularly the utility model has a tracheae between the intervalve of the water inlet pipe of S pipe and S pipe, the tracheae closed at both ends, nearly lower end and porose being connected of the nearly lower end of the water inlet pipe of S pipe at tracheae are connected with the upper end of the intervalve of S pipe is porose in the upper end of tracheae.

Operating principle of the present utility model is when water container begins draining, is water-filled in the whole piece pipe.After the water of water container drains, water in the pipe continues to discharge, cause the liquid level of the water inlet pipe of S pipe constantly to descend, when liquid level drops to hole that the nearly lower end of water inlet pipe is connected with the nearly lower end of tracheae and slightly during lower, air just can enter in the tracheae by the hole, in tracheae, rise to the top, and can enter the intervalve top with the hole that the upper end of the intervalve of S pipe communicates by the tracheae upper end, formed an atmospheric pressure effect on the top of the intervalve of S pipe like this, thereby destroyed the siphon condition in the S pipe, although the water of the outlet pipe of S pipe continues to discharge, but the water of the intervalve of S pipe can flow backward to the water inlet pipe of S pipe, till water level maintains an equal level in two pipes, this water level is higher than the hole that the nearly lower end of water inlet pipe of S pipe is connected with the nearly lower end of the intervalve of S pipe far away, so formed a water seal of trapping pipe, made going rotten of sewer, rancid gas and mosquito, do not come on the bacterium.

The utility model has the advantages that the drain function that not only has present common trapping pipe, and blocked that inner air tube communicates between sewer and the water container, stoped mildew and rot rancid air, mosquito and the bacterium of sewer to rise, prevented water container and the indoor pollution that is subjected to sewer, thereby guaranteed that people's is healthy.The utility model simple structure, be easy to processing, with low cost, practical, be easy to promote.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Fig. 1, organigram of the present utility model;

Fig. 2, profile construction schematic diagram of the present utility model.

Embodiment one,

Shown in Fig. 1,2, the utility model is on the basis that has common S type trapping pipe 1 and screw plug 3 now, particularly between the intervalve of the water inlet pipe of S pipe 1 and S pipe 1 tracheae 2 is arranged, tracheae 2 closed at both ends, in the nearly lower end of tracheae 2 porose being connected of the nearly lower end of water inlet pipe, manage porose being connected of upper end of 1 intervalve at the upper end and the S of tracheae 2 with S pipe 1.

The intervalve of the water inlet pipe of tracheae 2 of the present utility model and S pipe 1 and S pipe 1 can parallel and the axis in same plane.

The above tracheae 2 of the present utility model can be managed 1 the shared adjacent wall of water inlet pipe with S, tracheae 2 and the shared adjacent wall of intervalve of managing 1.

Embodiment two,

With embodiment one, just managing 2 is the pipe of a both ends open, and the mouth of pipe of its lower end is connected with the hole that S manages the nearly lower end of 1 water inlet pipe, and its upper end mouth of pipe is connected with the hole of the intervalve upper end of S pipe 1.

Claims

1, backsiphonage trapping pipe, generally can be used on the articles for use such as wash basin, bathtub in the daily life, include three perpendicular to horizontal plane and the continuous S pipe 1 that communicates that is connected into, screw plug 3 constitutes, it is characterized in that between the intervalve of the water inlet pipe of S pipe 1 and S pipe 1, a tracheae 2 being arranged, tracheae 2 closed at both ends in porose being connected of the nearly lower end of water inlet pipe of the nearly lower end of tracheae 2 and S pipe 1, are managed porose being connected of upper end of 1 intervalve at the upper end and the S of tracheae 2.

2, backsiphonage trapping pipe according to claim 1, the intervalve that it is characterized in that the water inlet pipe of tracheae 2 and S pipe 1 and S pipe 1 parallel and the axis in same plane.

3, backsiphonage trapping pipe according to claim 1 is characterized in that tracheae 2 can manage 1 the shared adjacent wall of water inlet pipe with S, the shared adjacent wall of intervalve of tracheae 2 and S pipe 1.
