[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1-6 A detachable evaporator includes a mounting frame 1, an evaporator body 2 disposed inside the mounting frame 1, a slot 4 formed in the inner wall of the mounting frame 1, an insert 3 rotatably connected to the top of one side of the evaporator body 2 via a pivot, the insert 3 being inserted into the inner wall of the slot 4, a ramp on one side of the insert 3, a sliding groove 7 formed at the top of the slot 4, a first spring 8 fixedly connected to the inner wall of the sliding groove 7, a limiting piece 10 fixedly connected to the bottom of the first spring 8, the bottom of the limiting piece 10 being disposed on one side of the insert 3, a pull rod 9 fixedly connected to the top of the limiting piece 10, the top of the pull rod 9 extending out of the sliding groove 7, two sets of side blocks 6 fixedly connected to both sides of the insert 3, two sets of side grooves 5 formed on both sides of the slot 4, the two sets of side blocks 6 being slidably connected to the inner walls of the two sets of side grooves 5.

[0023] To address the inconvenience of installing and removing the evaporator of the vehicle air conditioner, when installing the evaporator onto the mounting frame 1, the insert 3 can be rotated to align with the slot 4. Then, the four sets of inserts 3 are inserted into the inner wall of the slot 4, and the two sets of side blocks 6 on either side of the insert 3 are also inserted into the side grooves 5. Next, the pull rod 9 is pulled upwards. As the pull rod 9 moves upwards, it causes the bottom limiting plate 10 to move upwards as well. The upward movement of the limiting plate 10 compresses the first spring 8 until the limiting plate 10 is removed from the slot 4. The insert 3 can then pass through the limiting plate 10. When the insert block moves, the side block 6 can slide in the side groove 5 to limit the movement of the insert block and prevent the insert block from wobbling left and right. Then the pull rod 9 can be released to reset the first spring 8 downward and push the limiting plate 10 and the pull rod 9 to reset together. When the limiting plate 10 moves to one side of the insert 3, the position of the insert 3 and the side block 6 can be fixed, so that the position of the evaporator body 2 can be fixedly installed on the inner wall of the mounting frame 1. When it is necessary to remove the evaporator body 2, the pull rod 9 can be pulled to move the limiting plate 10 upward, so that the insert 3 can be taken out from the slot 4 to release the fixation of the evaporator body 2.

[0024] Reference Figure 4The top end of the pull rod 9 is fixedly connected to a mounting plate 11, which is L-shaped, and the top end of the mounting plate 11 is rotatably connected to a handle 12 via a pivot.

[0025] By setting an L-shaped mounting plate 11 at the top of the pull rod 9, it is easy to install the handle 12 at the top of the pull rod 9. When it is necessary to pull the pull rod 9, it is easy to pull up both sets of pull rods 9 at the same time by directly pulling the handle 12, which can improve the efficiency of installing and disassembling the evaporator body 2.

[0026] Reference Figure 4 The outer wall of the handle 12 is fitted with an anti-slip sleeve 13, and the outer wall of the anti-slip sleeve 13 is provided with anti-slip grooves 7. Multiple sets of anti-slip grooves 7 are provided and are distributed in parallel on the outer wall of the anti-slip sleeve 13.

[0027] By providing an anti-slip sleeve 13 on the outer wall of the handle 12, the friction of the anti-slip sleeve 13 can be increased by the multiple anti-slip grooves 7 provided on the outer wall of the anti-slip sleeve 13 when the handle 12 needs to be pulled, thereby making it easier for the user to pull up the handle 12.

[0028] Reference Figure 5 The top of the mounting frame 1 is rotatably connected to a cylinder 14. A second spring 15 is fixed to the inner wall of the cylinder 14. A base plate 16 is fixed to the bottom of the second spring 15. A connecting block is fixed to one side of the base plate 16. A limiting groove is opened on one side of the cylinder 14. The connecting block is slidably connected to the inner wall of the limiting groove. A pressure plate 17 is fixed to one end of the connecting block. The pressure plate 17 is located on the top of the handle 12.

[0029] By setting a cylinder 14 at the top of the mounting frame 1, after the evaporator body 2 is installed, the pressure plate 17 can be pushed upward. At this time, the pressure plate 17 will drive the connecting block and the base plate 16 to move upward and squeeze the second spring 15. Then, the cylinder 14 is rotated until the pressure plate 17 is rotated to the top of the handle 12. The pressure plate 17 can be released, and the second spring 15 will push the base plate 16, the connecting block and the pressure plate 17 to move downward together. The position of the handle 12 can be limited by the pressure plate 17 to prevent the handle 12 from shaking when not in use.

[0030] Reference Figure 3 The inner wall of the slot 4 is fixed with a side pad 18, which is made of rubber and is attached to one side of the insert 3.

[0031] By providing a rubber side pad 18 on the inner wall of the slot 4, a tight connection can be provided for the side of the insert 3 away from the limiting plate 10. At the same time, the rubber side pad 18 can also provide cushioning for the insert 3 when the evaporator body 2 shakes.

[0032] Working principle: To solve the problem of inconvenient installation and removal of the vehicle air conditioner evaporator, when it is necessary to install the vehicle air conditioner evaporator on the mounting frame 1, the insert 3 can be rotated to align the insert 3 with the slot 4. Then, the four sets of inserts 3 are inserted into the inner wall of the slot 4, and the two sets of side blocks 6 on both sides of the insert 3 are also inserted into the side grooves 5. Then, by directly pulling the handle 12, the two sets of pull rods 9 are pulled up simultaneously. The multiple sets of anti-slip grooves 7 on the outer wall of the anti-slip sleeve 13 improve the anti-slip sleeve 13. The friction of the lever 9 makes it easy for the user to pull the handle 12. When the lever 9 moves upward, it will drive the bottom limiting plate 10 to move upward as well. When the limiting plate 10 moves upward, it will squeeze the first spring 8 until the limiting plate 10 moves out of the slot 4. Then the insert 3 can pass through the limiting plate 10. When the insert moves, the side block 6 can slide in the side groove 5 to limit the movement of the insert and prevent the insert from wobbling left and right. Then the lever 9 can be released, so that the first spring 8 returns to its original position downward and pushes the limiting plate 10 to move upward. The limiting plate 10 and the pull rod 9 reset together. When the limiting plate 10 moves to one side of the insert 3, the position of the insert 3 and the side block 6 can be fixed, so that the position of the evaporator body 2 can be fixedly installed on the inner wall of the mounting frame 1. After the evaporator body 2 is installed, the pressure plate 17 is pushed upward. At this time, the pressure plate 17 will drive the connecting block and the base plate 16 to move upward and squeeze the second spring 15. Then rotate the cylinder 14 until the pressure plate 17 is rotated to the top of the handle 12. The pressure plate 17 can be released, so that the second spring 15 pushes the base plate 16, the connecting block and the pressure plate 17 to move downward together. The position of the handle 12 can be limited by the pressure plate 17 to prevent the handle 12 from shaking when not in use. When the evaporator body 2 shakes, the rubber side pad 18 provides cushioning for the insert 3. When it is necessary to remove the evaporator body 2, the pull rod 9 can be pulled to drive the limiting plate 10 to move upward, so that the insert 3 can be taken out from the slot 4 to release the fixation of the evaporator body 2.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
