[0022] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation of the present utility model.

[0023] The drawings are only for illustrative purposes and should not be construed as a limitation of this patent; for better illustrating this embodiment, some components in the drawings may be omitted, enlarged or reduced, and do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be said to be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0025] In modern air handling systems, the design of pipeline joints directly affects the performance and safety of equipment. Traditional pipeline joints often lack flexibility and adaptability, resulting in difficulties in fitting between different models of indoor units and pipe diameters. This not only increases inventory and production costs but also may lead to complexities in installation and maintenance.

[0026] In addition, traditional designs have insufficient management of condensate water, which easily causes condensate water leakage, affecting the stability of equipment operation and environmental hygiene. Existing sealing solutions often cannot effectively solve the problem of refrigerant leakage, and in specific installation conditions, such as in the case of side outlet pipes, it is difficult to provide an ideal sealing effect.

[0027] A flexible pipeline joint sleeve, the pipeline joint sleeve includes a stepped sleeve section 1 and a corrugated sleeve section 2;

[0028] The stepped sleeve section 1 is provided at the tail of the corrugated sleeve section 2, and a plurality of cuttable grooves 11 are provided on the stepped sleeve section 1;

[0029] A positioning pin 3 is provided at the head of the corrugated sleeve section 2, and the positioning pin 3 is used for guiding condensate water.

[0030] Specifically, as Figure 1 and Figure 2 shown, by adopting the corrugated sleeve section 2, the pipeline joint sleeve has flexibility. This sleeve section can easily adapt to the pipeline connection requirements in different directions and angles. For example, in a narrow corner of space, the corrugated sleeve section 2 can be bent at 90° to change the outlet direction of the machine, which not only improves the flexibility of installation but also enables the sleeve to better adapt to various complex spatial layouts, reducing the limitations and difficulties in the installation process.

[0031] The stepped sleeve section 1 enables the sleeve to closely fit different models of indoor units and pipe diameters, thus avoiding the problem of increasing inventory and production costs due to difficult fitting of traditional joints. In addition, cuttable grooves 11 are provided on the stepped sleeve section 1. The grooves 11 allow cutting according to actual needs to adjust the length and can closely fit different pipe diameters. Use tools such as cutting knives or saws to cut along the grooves 11 to adjust the pipe diameter to adapt to different specifications of pipe diameters.

[0032] The head of the corrugated sleeve section 2 is provided with a positioning pin 3. The positioning pin 3 can play a role in protecting the pipeline during installation and use. During use, it can fix the pipeline to avoid the pipeline being broken due to friction with the machine. And in some scenarios, the pipeline may generate condensate water. The corrugated sleeve section 2 can temporarily store the condensate water, and the excessive condensate water can be discharged from the pipeline joint sleeve through the positioning pin 3.

[0033] Preferably, a crimp connection port 21 for connecting with the pipeline is arranged inside the corrugated sleeve section 2.

[0034] Specifically, in some scenarios, since the pipeline of the machine cannot be bent greatly and the turning of the outlet pipe is required, at this time, the head of the pipeline joint sleeve proposed by the present utility model is connected to the machine, one end of the internal pipeline is connected to the outlet pipe of the machine, and the tail is connected to another pipeline. Since fireless connection is required in some scenarios, a crimp connection port 21 for connecting with the pipeline is arranged inside the corrugated sleeve section 2. Crimp connection through the crimp connection port 21 does not require any heat source or welding equipment, so no flame will be generated during the connection process. This makes it safer in many application scenarios, especially in flammable or explosive environments. Crimp connection will not release smoke or harmful gases, and its environmental protection performance is superior to heat connection methods such as welding. In addition, crimp connection can be used for the connection of various materials (such as copper, stainless steel, plastic, etc.), while the welding of different materials may require special technologies and equipment.

[0035] Preferably, positioning ribs 12 for fixing with a hoop are arranged on the stepped sleeve section 1.

[0036] Specifically, when using the pipeline joint sleeve, the positioning ribs 12 provide additional mechanical support, making the hoop more firm during the fixing process, avoiding sliding or loosening caused by external force or vibration. By increasing the contact area with the hoop, the positioning ribs 12 can effectively disperse the force applied on the hoop and improve the overall stability. The setting of the stepped sleeve section 1 and the positioning ribs 12 can adapt to pipelines of different diameters and specifications, enhancing the versatility of the equipment.

[0037] Preferably, a threaded connection port 22 for connecting with the pipeline is also arranged inside the corrugated sleeve section 2.

[0038] Specifically, when the outlet pipe does not need to turn, the threaded connection port 22 can be used to connect with the pipeline. Through the meshing of the threads, the threaded connection port 22 realizes a mechanical locking method, making the pipeline connection more stable and reducing the risk of loosening and leakage during use. Threaded connections usually use sealing rings or gaskets in combination, which can effectively prevent medium leakage and ensure the airtightness and liquid tightness of the connection. This is particularly important for pipelines carrying gases or liquids.

[0039] Preferably, the length of the corrugated casing section 2 is greater than that of the stepped casing section 1 .

[0040] Specifically, the length of the corrugated casing section 2 is greater than that of the stepped casing section 1, which enhances the flexibility and adaptability of the system and can better cope with thermal expansion and contraction, thereby improving the overall sealing and reliability. At the same time, the longer design facilitates installation and maintenance, optimizes fluid flow, reduces fluid resistance, and ensures the safe and stable operation of the system in complex environments.

[0041] like Figure 1 and 2 As shown, an air handling unit 4 utilizes the aforementioned pipe joint sleeve. Specifically, air passes through an air filter, is processed by the air handling unit 4, and is then discharged from the pipeline. The positioning pin 3 at the head of the corrugated sleeve section 2 is mounted on the housing of the air handling unit 4. The corrugated sleeve section 2 and the stepped sleeve section 1 are sleeved onto the outlet pipe of the air handling unit 4.

[0042] The air handling unit 4 further includes a water receiving pan 41 , into which condensed water in the corrugated sleeve section 2 flows through the positioning pins 3 .

[0043] Specifically, in order to better handle the condensed water generated by overcooling in the pipeline, a water receiving pan 41 is provided in the air handling unit 4. At the beginning, the condensed water generated by the pipeline will be stored in the corrugated sleeve section 2. When the condensed water increases to a certain level, the condensed water overflows from the corrugated sleeve section 2 and flows into the water receiving pan 41 along the positioning pin 3, thereby solving the problem of condensed water generated in the pipeline.

[0044] The air handling unit 4 further includes a refrigerant leakage sensor 42 .

[0045] Specifically, the air handling unit 4 is equipped with a refrigerant leakage sensor 42. Refrigerant refers to the liquid or gas circulated in refrigeration, air conditioning and heat pump systems. It can monitor the status of the refrigerant system in real time to ensure the safe and efficient operation of the equipment. In scenarios such as air handling, the sensor can detect refrigerant leaks in time, such as air conditioners. This design can reduce maintenance costs and downtime, while improving energy efficiency and protecting the environment, and ensuring the stability and reliability of the system.

[0046] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
