Breathing apparatus

Abstract

The invention relates to a breathing apparatus, which comprises a breathing body of a rigid container, an air bubble, a retaining valve and a water inlet valve; the breathing body is provided with a water inlet and a water outlet; the air bubble is formed by placing a low-boiling-point substance inside a closed flexible container; the breathing body is divided into an upper breathing chamber and a lower water storage chamber, and the breathing chamber is communicated with the water storage chamber through a breathing chamber first water outlet; the water inlet valve is arranged on the upper end of the breathing chamber, the water inlet valve comprises a valve body of a rigid container and syphon pipe and a water inlet pipe, which are arranged inside the valve body, the water absorption end of the syphon pipe is arranged on the bottom part area of the valve body, the water outlet end of the syphon pipe passes through the bottom end of the valve body to be communicated with the breathing chamber, the upper end of the water inlet pipe passes through the top part of the valve body to be connected with the water inlet of the breathing body, the lower end of the water inlet pipe is arranged on the water absorption end of the syphon pipe, the upper part of the valve body is provided with a communication port which is communicated with the breathing chamber, the communication port is higher than the top part of the syphon pipe, and the air bubble is arranged inside the breathing chamber. The breathing apparatus has the advantages that: no power supply is required during the circulation of the cold water and the hot water, so the energy can be saved, and the cost is low.

Description

technical field [0001] The invention relates to a respirator for circulating hot and cold water. Background technique [0002] The applicant of the present invention has previously proposed an invention patent (patent number: ZL200910184270.1) named "breather that can circulate hot and cold water". The respirator mainly consists of the breathing body of the rigid container and the air bubbles placed in the breathing body, see figure 2 . The bubbles are formed by a low-boiling substance (such as cyclopentane) in a flexible airtight container. The respirator is generally placed in the circuit of cold and hot water circulation, such as on the hot water pipeline of a solar water heater, and a one-way valve is set on the water inlet and water outlet of the breathing body. The pressure change caused by the volume change caused by the phase change of the low boiling point substance is used to open or close the one-way valve to realize the circulation of cold and hot water. In t...

Problems solved by technology

However, if the above-mentioned existing technical means are used to realize, the structure of the respirator will inevitably be complicated, and the cost will be greatly increased. At the same time, a corresponding power supply must be provided when the cold and hot water circulate
