Problems solved by technology

[0005] (1) During the gas storage process, the air outlet pipe 8 is blocked and its interior is at normal pressure. During the release process, the high-pressure gas in the air storage tank 3 must completely pass through the air outlet pipe 8 and then be released from the air outlet nozzle 4, resulting in The high-pressure gas is released through a long path and forms a loss in the gas outlet pipe 8, which affects the pressure released at the gas outlet, thereby affecting the dredging effect
[0006] (2) In order to ensure the dredging effect, a large air flow needs to be generated at the air outlet. Therefore, it is necessary to ensure that the inner diameter of the air outlet pipe 8 connected to the air outlet is relatively large, usually about 10mm, in order to reduce the path and loss of high-pressure gas , which limits the length of the gas outlet pipe and the gas storage tank. In the case of a shorter length, in order to ensure sufficient air pressure, the diameter of the gas storage tank can only be increased to store more high-pressure gas
[0007] (3) When the air storage tank is short, usually 30~40cm, when the toilet is unblocked, the water is easy to splash on the body of the unblocker
[0008] (4) The short and thick air storage tank is usually produced and processed by injection molding, and the connection structure between it and the air outlet pipe is relatively complicated, resulting in relatively high production costs

Embodiment 1

[0080] The air pressure type pipeline dredging device of the present embodiment, as figure 1 As shown, it includes a stored-air pressure release mechanism 100 and a handle 200 connected to one end of the stored-air pressure release mechanism 100 .

[0081] In this example, if Figure 2-5 As shown, the air storage type pressure release mechanism 100 of this embodiment includes an air storage tank 10 , and the air storage tank 10 includes a cylinder body 11 and an end cap 12 fixedly connected to one end of the cylinder body 11 . Wherein, the cylinder body 11 is provided with an air storage chamber 13 inside, and the end of the air storage chamber 13 away from the end cap 12 is closed.

[0082] In this embodiment, the end cap 12 is provided with a pressure release channel 14, and the end of the pressure release channel 14 facing the cylinder body 11 is provided with a pressure release port 15. As a preference, the pressure release port 15 is covered with a silicone sleeve 16 for...

Embodiment 2

[0100] The air pressure type pipeline dredging device of the present embodiment, as Figure 11 As shown, the structure of the air storage type pressure release mechanism 100 is the same as that of Embodiment 1, the difference lies in the inflation system and the deflation mechanism.

[0101] The inflation system of this embodiment, such as Figure 11 As shown, it includes an electric inflator 43 disposed in the handle 200 , the electric inflator 43 is connected to the air pipe 20 through a connecting pipe 41 , and the handle 200 is provided with a start-stop switch 44 for starting / closing the electric inflator 43 .

[0102] As a preference, in this embodiment, in order to facilitate the installation and connection of the related parts of the inflation system and the deflation mechanism, an air inlet end cover 24 is provided at the closed end of the air storage tank, and the air inlet end cover 24 is provided with a The intake chamber 26 communicated with the intake pipe 20 . ...

Embodiment 3

[0107] The air pressure type pipeline dredging device of the present embodiment, as Figure 12 , Figure 13 As shown, the structure of the air storage type pressure release mechanism 100 is the same as that of Embodiment 1 and Embodiment 2, the difference lies in the inflation system and the deflation mechanism.

[0108] The inflation system of this embodiment, such as Figure 12 , Figure 13 As shown, it includes an air cylinder outer cylinder 60 installed in the handle 200, and the air cylinder outer cylinder 60 can move axially in the handle. An inflator inner rod 61 is installed in the inflator outer cylinder 60, and a piston 62 is arranged at the inner end of the inflator inner rod 61. The inflator outer cylinder 60 and the inflator inner rod 61 form an existing manual inflator.

[0109] Wherein, the outer cylinder 60 of the inflator and the vent tube 20 are communicated through the one-way valve 42. During the inflation process through the inner rod 61 of the inflator...

Abstract

The invention discloses an air storage type pressure release mechanism and an air pressure type pipeline dredging device.The air storage type pressure release mechanism comprises an air storage cylinder, a ventilation pipe, an air plug, an inflation system and an air deflation mechanism, an air storage cavity is formed in the air storage cylinder, a pressure release opening is formed in one end of the air storage cavity, the ventilation pipe is arranged in the air storage cavity, and the air plug is arranged in the air storage cavity; the air plug is provided with a first position in sealed contact with the breather pipe and a second position in sealed contact with the pressure release port, in the inflation process and after inflation is completed, the air pressure in the breather pipe is the same as that in the air storage cavity, in the deflation process, due to the fact that a high-pressure environment is formed in the breather pipe, the air pressure can be rapidly reduced after the breather pipe is communicated with the outside, and the pressure release port is opened. A larger pressure difference instantly occurs in the vent pipe and the gas storage cavity, so that the response speed of the gas plug is fast enough; in the pressure release process, compressed gas in the gas storage cavity is directly discharged from the pressure release opening and does not pass through the breather pipe, and the compressed gas has no stroke loss in the release process.

Description

technical field [0001] The invention relates to an air storage type pressure release mechanism and an air pressure type pipeline dredging device. Background technique [0002] In daily life, the sewer pipes corresponding to toilets, sinks, and vegetable sinks are often blocked. There are many ways to clear the blocked pipes. In recent years, a kind of pneumatic pipe dredging device commonly known as Yi Pao Tong has become popular, which uses instantaneous high pressure release to flush the pipe open. [0003] For example, the notification number is a kind of toilet dredger disclosed by the Chinese invention patent of CN209798921U, which is a gun-through type pipeline dredger. The toilet dredger with the above structure, when in use, inflates the air nozzle 5 through the air cylinder, and at this time, the gas enters the air inlet and outlet chamber 14 and starts to block the air plug 15 against the end of the air outlet pipe 8, and continues to inflate at this time, Stop p...
