The connector of the kind of the official, the [previous technique] the connector of the conventional collection tube, such as the application of the "Improvement of the collection tube" patent, the first channel, the second channel and the third channel of the 095 095211645 , the first ... and ° °, the second end of the second channel is difficult to pass - pass / one pass and the channel U channel and the third channel of the hose, the second, the channel is placed in a spring and a steel one In the two channels, the sealing ring has a sealing ring, a sealing ring and a - limiting member; the upper steel ball can be pushed by the backflow of gas;: gas ~ hour, step 1 · ^ v 1 mountain seal; clothing, occlusion The passage of the seal ring, gas ~ out. Because the structure is to prevent the steel ball from occluding the port between the first passage and the first passage, the wall is pushed up by a magazine wall 4" so that the steel ball is not inadvertently placed into the ball. The mouth of the system, 3 Γ (4) Shuaier: ―, lion Jing parts t 9 books, 2, increase the working hours cost of the spring parts; 3, increase the inspection 疋 No device _ parts cylinder cost. So how to avoid the spring Zero = without the above-mentioned deficiency, can provide a safer collection of the master's 'has become the place of this research and development. [New content] The main purpose of this creation is to address the aforementioned lack of supply - the collection of Connection 3 'M364155 head improvement, with the first channel, the second channel and the third channel, the second channel of the second channel is separated by the first channel and the third channel, the second channel has - free In the third channel, there is a tight fit method - a sealing ring and a limiting member; by means of the above-mentioned members, when the gas is recirculated, the free piece can be pushed by the return gas to resist the sealing ring, the passage of the sealing ring, Prevent gas phase. In order to make the above and other solutions of this creation, the following is a better example of the merits of the abstract. The money is obviously explained. Please refer to the first and second figures, ^^^^^^^^^^^^^^^^^^^^^^ The head is provided with a connector that is small to large and not a Jiji/% connector. The channel 12 and the third channel 13, the mn-channel I!, the second 11 and the third channel are connected to each other.

In order to make the free piece = end 23 hemispherical toward the first "the sword" means that the inner movement is free and the section of the wall 24 is formed into four The square, the recess 22 of the free piece 2 is smaller than the diameter of the second passage 12, and the width a of the most diagonal line is equal to or slightly, a sealing ring 3 and a limiting member 4; The passage 31, 41, the seal ring 3, the garment 1 and the restriction member 4 respectively have a passage 4 communicating with the passage 41; the sealed end is distinguished from the second passage 12 and the second end 2 3; the restriction member 4 ^ the diameter of the ventilation 31 is smaller than the gas of the self-contained gas cylinder 4! It can be connected with the gas cylinder (not shown) without entering the third passage free member 2 due to the sealing ring 3 Sliding in the L channel 12. The 垓 free piece 2 is limited to the second M364155, so that the item can better understand the content of the creation, the actual action situation and the principle description as follows: the knowledge and advantages, Referring to the first and second figures, when the gas cylinder 41 enters and passes through the passage of the seal ring 3, the passage of the restricting member 4 is pushed away from the member 2 due to the age of the annular wall 24 of the recess 22 of the free member 2. The sealing ring 3; 24 and the inner wall of the second passage 12 are formed with a square surface to form a square, and the ring wall flows into the cooking device after entering the first passage 11, so that the gas can be referred to the third figure again. Show, when abandoned by the restriction. Depletion and supply interruption. The gas entering the upper channel 41 of the other gas cylinder is entered by the first passage 11. Since the trunk 2 of the free member 2 recirculates and is larger than the diameter of the first passage 11, the gas will equal or slightly make the hemisphere second. The end 23 occludes the sealing ring 3 at noon 2, and seals the ring 3, and thus, the user can easily replace the exhausted 1^ to prevent the gas from flowing out. It is very desirable to make a fire due to loss. Therefore, it can avoid the novelty that is unprecedented in man-made, and can understand the creative piece, and the enhanced effect has been defined by the spring zero of the above-mentioned and known technology, instead of the equivalent range of the scope of the specification. Changes or modifications are all within the scope of this creation.
