[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model provides a technical solution: an air outlet filter bag that is easy to install, including a bag opening installation ring 1 and a filter bag body 3. The lower side of the bag opening installation ring 1 is provided with a bag opening plug-in groove 2, and the bag opening plug-in groove 2 cooperates with the bag opening of the filter bag body 3 to complete the installation of the two. The bag opening plug-in groove 2 includes a fixed groove 21 and an insertion groove 22. The insertion groove 22 is small inside and large outside, and the fixed groove 21 is arranged on the inner side of the insertion groove 22. This design makes it easier to insert the filter bag body 3. An incision is provided on the bag opening installation ring 1, and the bag opening installation ring 1 has a tendency to close toward the incision. The bag opening installation ring 1 designed in this way tends to be close to the wall of the air outlet pipe, making the connection between the two tighter.

[0022] The side wall of the bag opening mounting ring 1 is provided with a plurality of bag opening fixing mechanisms, the bag opening fixing mechanisms include screws 4, the side wall of the bag opening mounting ring 1 is provided with threaded holes 5, and the threaded holes 5 are connected to the fixing grooves 21, and the threaded holes 5 cooperate with the screws 4. In this way, after the screws 4 are completely screwed in, they will also penetrate the filter bag body 3 to fix its position.

[0023] In order to ensure that the bag mouth mounting ring 1 is more firmly fixed to the air outlet pipe wall, a locking mechanism can be designed at the incision of the bag mouth mounting ring 1. The locking mechanism is arranged on both sides of the incision. The locking mechanism includes a pair of limit blocks 9 and a directional rod 10. The pair of limit blocks 9 are rotatably connected to the two sides of the incision of the bag mouth mounting ring 1, respectively. The limit blocks 9 are provided with directional openings, and the directional rod 10 is inserted into the directional openings. The two ends of the directional rod 10 are provided with limit blocking blocks 12 for limiting the movable distance of the directional rod 10. The limit blocks 9 are provided with locking screws 11, and the locking screws 11 are connected to the directional openings. After the bag mouth mounting ring 1 is close to the air outlet pipe wall, the locking screws 11 are rotated to lock it.

[0024] In order to ensure that the folds of the filter bag body 3 at the incision can also be closed to prevent the exhaust gas from overflowing along the opening, the side wall of the directional rod 10 is provided with a plurality of filter bag insertion notches 13. When the filter bag body 3 has some surplus at the incision of the bag mouth mounting ring 1, it only needs to be stuck in the filter bag insertion notch 13.

[0025] Working principle: Before use, first insert the filter bag body 3 into the bag opening insertion slot 2, and complete the insertion and fixing with the screw 4. At this time, the filter bag body 3 will be firmly fixed with the bag opening installation ring 1, and then the bag opening installation ring 1 is sleeved on the outer side of the air outlet pipe wall. At this time, the directional rod 10 will move relative to the limit block 9, and the locking screw 11 fixes the position of the directional rod 10, and the overall locking of the device and the air outlet pipe wall can be completed.

[0026] If some folds of the filter bag body 3 are still not closed at the incision, it only needs to be inserted into the filter bag insertion notch 13.

[0027] See also Figure 4 The utility model also provides another technical solution, which is different from the above technical solution in that: the bag opening fixing mechanism includes a nail 6, the side wall of the bag opening mounting ring 1 is provided with a plug hole 7, and the plug hole 7 is connected to the fixing groove 21, the nail 6 cooperates with the plug hole 7, and a spring 8 is installed between the protrusion of the nail 6 and the side wall of the bag opening mounting ring 1. The other technical features remain unchanged.

[0028] The elasticity of the spring 8 can ensure the stability of the nail 6 when it is inserted into the insertion hole 7. This design can also achieve the effect of fixing the filter bag body 3. When the filter bag body 3 needs to be replaced, just pull out the nail.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
