[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention: An air-conditioning condensate pipe sealing detection device, including:

[0023] An air pump 1, and the air outlet end of the air pump 1 is connected with an air supply pipe 11;

[0024] A first sealing assembly 2, a second sealing assembly 3 and a detection pool 4. The first sealing assembly 2 is connected to the other end of the air supply pipe 11. The second sealing assembly 3 includes a second sleeve plug 31. The first sealing assembly 2 and the second sealing assembly 3 respectively seal the two ends of the condensate pipe. The detection pool 4 is used for placing the condensate pipe, and a large number of small foam balls are placed inside the detection pool 4. When the air pump 1 is powered on and started, air is supplied to the inside of the condensate pipe through the air supply pipe 11 and the first sealing assembly 2. If gas leakage occurs, it will blow the small foam balls inside the detection pool 4 to flow, so as to visually detect whether the condensate pipe leaks;

[0025] The second sealing assembly 3 includes a second sleeve plug 31. The second sleeve plug 31 is sleeved on the outside of the condensate pipe, and a second inner sleeve 32 is arranged inside the second sleeve plug 31. A guide ring 34 is fixedly connected to the inner wall of the second inner sleeve 32. A guide shaft 35 is inserted into the guide ring 34. One end of the guide shaft 35 is fixedly connected to a sealing piston 36, and the sealing piston 36 is slidably connected to the inner wall of the second inner sleeve 32. An air leakage ring 37 is provided on the inner wall of the second inner sleeve 32. Through the setting of this structure, when the condensate pipe is continuously supplied with air and the internal pressure is relatively high, the gas will push the sealing piston 36 to displace, so as to realize the leakage of gas through the air leakage ring 37, avoiding damage such as deformation of the condensate pipe under excessive pressure, and greatly improving the safety of the device during the detection process.

[0026] Further, the first sealing assembly 2 includes a first socket plug 21. An air supply pipe 11 is connected to the air inlet end of the first socket plug 21. A first inner sleeve 22 is arranged inside the first socket plug 21, and the first inner sleeve 22 is inserted into the inside of the condensation pipe. The first socket plug 21 is wrapped around the outside of the condensation pipe. Through the setting of this structure, in cooperation with the air supply pipe 11, inflation treatment of the condensation pipe is realized. With the hand-tightening and fastening of the first clamp 23, the stability of its installation is ensured.

[0027] Further, a first limiting ring is arranged on the outer wall of the first socket plug 21, and a first clamp 23 passes through between the first limiting rings. The first clamp 23 is wrapped around the outer wall of the first socket plug 21.

[0028] Further, a second limiting ring is arranged on the outer wall of the second socket plug 31, and a second clamp 33 passes through between the second limiting rings. The second clamp 33 is wrapped around the outer wall of the second socket plug 31. A second inner sleeve 32 is inserted into the inner wall of the condensation pipe. First air holes are evenly formed in a circumferential direction on the guiding ring 34, and second air holes are formed in the second socket plug 31 corresponding to the first air holes. Through the setting of the first air holes and the second air holes, in cooperation with the air leakage ring 37, the leakage of gas is realized, avoiding excessive air pressure inside the condensation pipe.

[0029] Further, two retaining rings are arranged on the outer wall of the guiding shaft 35, and the two retaining rings are respectively located on both sides of the guiding ring 34. The diameter of the retaining ring is not greater than the inner diameter of the distribution of the air holes. Guiding holes adapted to the guiding shaft 35 are formed at the centers of the guiding ring 34 and the second socket plug 31. The diameter of the sealing piston 36 is smaller than the diameter of the air leakage ring 37. The diameter of the air leakage ring 37 is larger than the inner diameter of the second inner sleeve 32. A spring 38 is sleeved outside the guiding shaft 35. One end of the spring 38 abuts against the inner wall of the second socket plug 31, and the other end of the spring 38 abuts against the outer wall of the retaining ring far from the sealing piston 36. Through the setting of the spring 38, a certain resistance is provided to the sealing piston 36. Therefore, when the air pressure thrust inside the condensation pipe is greater than the elastic force of the spring 38, the movement of the sealing piston 36 can be realized, ensuring sufficient air pressure inside the condensation pipe to detect the leakage point.

[0030] Working principle: The air pumps 1 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here. When this utility model is in use, first, the first sealing assembly 2 and the second sealing assembly 3 are tightly installed. Further, the condensation pipe is placed inside the detection pool 4. By starting the air pump 1, the air supply pipe 11 cooperates with the first sealing assembly 2 to continuously inflate the inside of the condensation pipe. When there is sufficient gas inside the condensation pipe, it will leak to the outside through the leakage point, realizing the blowing of the foam balls inside the detection pool 4. On the contrary, when there is no leakage, the air pressure continuously increases, which will push the sealing piston 36, and thus air leakage is realized through the second sealing assembly 3, avoiding deformation of the condensation pipe caused by continuous air supply.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
