Description

Technical Field

[0001] This application relates to the field of air coolers, and more particularly to a duct connection structure for air coolers. Background Technology

[0002] Evaporative air coolers are highly efficient and energy-saving cooling devices that utilize evaporative cooling technology. Through air exchange, they effectively lower indoor temperatures while providing a fresh air environment. Evaporative air coolers are suitable for various locations, such as factories, warehouses, and offices. Not only are they energy-saving and power-efficient, but they are also easy to install and operate, quickly improving indoor comfort and making them an ideal choice for cooling in summer.

[0003] Currently, when installing evaporative air coolers, the air ducts connecting to the indoor unit need to be installed on the air inlet and outlet ducts of the air cooler. The air ducts are fitted onto the ductwork, and a sealing ring is installed on the outer wall of the duct to seal the connection between the duct and the air duct. The sealing ring is usually circular or rectangular in cross-section. If the sealing ring fits extremely tightly against the inner wall of the duct, the sealing effect is optimal, but the installation of the air duct is more difficult. If the sealing ring fits relatively tightly against the inner wall of the duct, the installation is easier, but the sealing effect will be somewhat reduced. Utility Model Content

[0004] In order to improve the sealing effect of the sealing ring while facilitating the installation of the duct, this application provides a duct connection structure for an air cooler.

[0005] The duct connection structure for an air cooler provided in this application adopts the following technical solution:

[0006] A duct connection structure for an air cooler includes a pipe connected to the air cooler. An installation annular groove is formed on the outer wall of the pipe. A sealing ring is disposed in the installation annular groove of the pipe. At least one sealing ring is fixedly disposed on the sealing ring. When the duct is sleeved and installed on the pipe, the duct pushes the sealing ring to tilt, and the side wall of the sealing ring abuts against the inner wall of the duct.

[0007] By adopting the above technical solution, during duct installation, the duct is slidably fitted onto the pipe, with the duct end first contacting the sealing ring. When the duct pushes the sealing ring to tilt, the duct can be fitted onto the sealing ring, facilitating duct installation. At this time, the side wall of the sealing ring abuts against the inner wall of the duct, thereby increasing the sealing effect of the sealing ring. This arrangement uses sealing rings to seal the connection between the duct and the pipe, improving the sealing effect of the sealing ring while facilitating duct installation.

[0008] Preferably, multiple sealing rings are provided at intervals along the axial direction of the pipe.

[0009] By adopting the above technical solution, after the air duct is installed, multiple sealing rings abut against the inner wall of the air duct to seal it, thereby further improving the sealing effect of the sealing rings.

[0010] Preferably, the diameter of the plurality of sealing rings gradually decreases along the installation direction of the duct sleeve.

[0011] By adopting the above technical solution, after the duct is installed, the larger diameter sealing ring will tilt down and press on the smaller diameter sealing ring, thereby further improving the sealing effect of the sealing ring.

[0012] Preferably, the sealing ring has a trapezoidal cross-section, the width of the outer peripheral sidewall of the sealing ring is greater than the width of the inner peripheral sidewall, and a plurality of the sealing rings are fixedly disposed on the outer peripheral sidewall of the sealing ring.

[0013] By adopting the above technical solution, the cross-section of the sealing ring is trapezoidal, and multiple sealing rings are installed on the outer peripheral sidewall with a larger width of the sealing ring, thereby making the multiple sealing rings more stable during the installation of the air duct.

[0014] Preferably, there is a movable gap between the sealing ring and the inner wall of the mounting ring groove.

[0015] By adopting the above technical solution, the movement gap during the sliding installation of the duct allows for slight movement of the sealing ring, thereby further facilitating the installation of the duct.

[0016] Preferably, the end of the pipe closest to the duct installation side is recessed.

[0017] By adopting the above technical solution, the end of the pipe is recessed, which makes it easier for the air duct to be installed on the pipe.

[0018] Preferably, a retaining ring is fixedly provided on the outer wall of the sealing ring. The retaining ring is located on the side of the sealing ring away from the duct installation end. A deformation ring groove is opened on the upper side wall of the sealing ring near the retaining ring. The deformation ring groove is located at the connection between the sealing ring and the sealing ring, and the sealing ring is inclined to abut against the retaining ring.

[0019] By adopting the above technical solution, during the duct installation process, the deformation ring groove facilitates the formation of the sealing ring by the duct. The sealing ring is inclined and abuts against the retaining ring, which can seal the connection between the duct and the pipeline, improving the sealing effect of the sealing ring and facilitating the installation of the duct.

[0020] Preferably, a retaining ring is fixedly provided on the outer periphery of the sealing ring away from the sealing ring, and the retaining ring is inclined near the side wall of the sealing ring, with the retaining ring abutting against the inclined side wall of the retaining ring and the inner side wall of the air duct.

[0021] By adopting the above technical solution, when the duct is installed, the duct causes the sealing ring to tilt, and the sealing ring causes the retaining ring to move. The retaining ring is locked and fixed between the tilted side wall of the retaining ring and the inner side wall of the duct, thereby further improving the sealing effect of the sealing ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Using a sealing ring, when installing the duct, the duct is slidably fitted onto the pipe. The end of the duct first contacts the sealing ring. When the duct pushes the sealing ring to tilt, the duct can be fitted onto the sealing ring, which facilitates the installation of the duct. At this time, the side wall of the sealing ring is pressed against the inner wall of the duct, which can increase the sealing effect of the sealing ring.

[0024] 2. With the help of the movable gap, during the sliding installation of the duct, the movable gap allows the sealing ring to move slightly, thereby further facilitating the installation of the duct.

[0025] 3. Through the retaining ring, during the duct installation process, the deformation ring groove facilitates the formation of the sealing ring by the duct. The sealing ring is inclined and abuts against the retaining ring, which can seal the connection between the duct and the pipe, improving the sealing effect of the sealing ring and facilitating the installation of the duct.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] Example 1:

[0033] This application discloses a duct connection structure for an air cooler.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A duct connection structure for an air cooler includes a pipe, which is fixedly installed on the air cooler. The end of the pipe near the installation side tapers inward, and the diameter of the pipe end is smaller than the diameter of the middle part of the pipe. The duct is slidably fitted onto the pipe from the taper end, thereby facilitating the installation of the duct.

[0035] A mounting groove is formed by an inward indentation on the outer wall of the pipe near its recessed end. A sealing ring is installed within the mounting groove. Both the mounting groove and the sealing ring have trapezoidal cross-sections along the pipe's axis. The outer wall of the sealing ring away from the pipe is parallel to the inner wall of the sealing ring near the pipe, and the width of the outer wall of the sealing ring away from the pipe is greater than the width of the inner wall of the sealing ring near the pipe.

[0036] A sealing ring is integrally formed on the outer wall of the sealing ring away from the pipe. Two sealing rings are installed, and the two sealing rings are installed at intervals along the axial direction of the pipe. The diameter of the sealing ring on the side closer to the concave end of the pipe is larger than the diameter of the sealing ring on the side farther from the concave end of the pipe.

[0037] During duct installation, the duct is first fitted onto the pipe from the recessed end. Then, the duct is slid, initially contacting the larger diameter sealing ring. This causes the larger diameter sealing ring to tilt, with its sidewall pressing against the inner wall of the duct. As the duct continues to slide, the tilt angle of the larger diameter sealing ring gradually increases. When the larger diameter sealing ring contacts the smaller diameter sealing ring, it pushes the smaller diameter sealing ring to tilt. Thus, the tightness between the sealing ring and the inner wall of the duct is not high during installation, facilitating the installation process.

[0038] As the duct continues to slide and install, when the smaller diameter sealing ring moves and presses against the sealing ring, the duct can hardly continue to slide. At this point, the side wall of the larger diameter sealing ring presses against the inner wall of the duct, and the side wall of the smaller diameter sealing ring presses against the outer wall of the sealing ring, thereby sealing the connection between the duct and the pipe and increasing the sealing effect of the sealing ring.

[0039] There is a movable gap between the inner circumferential wall of the sealing ring and the inner circumferential wall of the pipe located in the mounting groove. During duct installation, the sealing ring can move slightly within this gap, facilitating duct installation. When the duct is fully installed, the sealing ring is pressed against the mounting groove and seals the movable gap, preventing leakage at this point.

[0040] The implementation principle of the duct connection structure for an air cooler according to an embodiment of this application is as follows: When installing the duct, the duct is slidably fitted onto the pipe. The end of the duct first contacts the sealing ring. When the duct pushes the sealing ring to tilt, the duct can be fitted onto the sealing ring, which facilitates the installation of the duct. At this time, the side wall of the sealing ring abuts against the inner wall of the duct, thereby increasing the sealing effect of the sealing ring.

[0041] Implementation 2:

[0042] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that a single sealing ring is installed. A retaining ring is integrally formed at the end of the sealing ring furthest from the sealing ring. The retaining ring has a circular cross-section along the pipe axis. A deformation ring groove is formed on the side of the sealing ring furthest from the concave end of the pipe and near the sealing ring. A retaining ring is integrally formed on the outer peripheral sidewall of the sealing ring, near the deformation ring groove. The retaining ring has a right-angled triangle cross-section along the pipe axis, with the hypotenuse of the right-angled triangle located near the sealing ring.

[0043] During duct installation, the duct pushes the sealing ring to tilt, and the deformed ring groove facilitates this tilting, making duct installation easier. The sealing ring moves the retaining ring, and when the retaining ring abuts against the inclined wall of the retaining ring, it stops moving. At this point, one side of the retaining ring is pressed against the inclined wall of the retaining ring, and the other side is pressed against the inner wall of the duct, thus sealing the connection between the duct and the pipe.

[0044] The implementation principle of Embodiment 2 of this application is as follows: a retaining ring is used in conjunction with a retaining ring to seal the connection between the air duct and the pipe. With the use of a single sealing ring, the connection between the air duct and the pipe can be sealed, thereby making the air duct installation more convenient.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
