Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0053] Please see Figures 1 to 7 In the first embodiment of this utility model, a dust collection bag 100 includes: a bag body 10 and a connecting structure 20. The connecting structure 20 is used to connect with a dust collection pipe. The connecting structure 20 is fixed to the bag body 10. The connecting structure 20 includes: a retaining plate 21, a sealing ring 22, a dust cover 23, and a reset spring 24. The sealing ring 22 has a dust collection inlet 221. The retaining plate 21 is fixed to the bag body 10. Specifically, the retaining plate 21 is fixed to the bag body 10 by adhesive. As an optional embodiment, the retaining plate is fixed to the bag body by sewing or ultrasonic welding. The reset spring 24 is used to reset the dust cover 23 to cover the dust collection inlet 221. The sealing ring 22 is disposed on the retaining plate 21. The dust cover 23 is connected to the retaining plate 21 and the dust cover 23 is aligned with the dust collection inlet 221. The reset spring 24 is installed on the dust cover 23. The dust cover 23 is used to prevent impurities from splashing out when replacing or removing the dust collection bag 100.

[0054] In use, the end of the suction tube is inserted into the bag body 10 through the dust collection inlet 221. The end of the suction tube overcomes the force of the reset spring 24, pushing inward to open the dust cover 23. When the end of the suction tube is pulled out, the reset spring 24 causes the dust cover 23 to reset, blocking the dust collection inlet 221. The sealing ring 22 wraps around the top of the suction tube, thus achieving a sealing effect and preventing large particles of impurities from leaking out from the outside of the suction tube.

[0055] In one specific implementation, the bag body 10 is composed of a breathable material 11 and a protective material 12. The protective material 12 is aligned with the dust collection inlet 221. The breathable material 11 is breathable. The protective material 12 is not breathable. Specifically, the breathable material 11 can be a filter cloth or filter paper. The protective material 12 can be a protective fabric or other materials. The protective material 12 is integrated with the other parts of the bag body 10 by sewing, pasting, or ultrasonic welding, using splicing or lining processes.

[0056] The protective material 12 is designed to protect against large particles of impurities entering through the suction pipe, preventing these particles from directly impacting the breathable material 11 and causing damage to it.

[0057] In one specific embodiment, the dust cover 23 includes a handle 231 and a cover plate 232. The handle 231 and the cover plate 232 are integrally formed. The handle 231 is fixed to the retaining plate 21. The cover plate 232 covers the dust collection inlet 221. In another specific embodiment, one end of the reset spring 24 is located on the handle 231, and the other end of the reset spring 24 is located on the cover plate 232. The handle 231 itself can function as a plastic spring. Furthermore, the reset spring 24 also serves to reset the cover plate 232.

[0058] In one specific implementation, the cover plate portion 232 has a spring clip retaining clip 2321 and a spring clip anti-reverse protrusion 2322. The spring clip retaining clip 2321 fixes the reset spring clip 24 to the cover plate portion 232. The reset spring clip 24 has an anti-reverse hole 241. The spring clip anti-reverse protrusion 2322 is located within the anti-reverse hole 241 to prevent the reset spring clip 24 from sliding relative to the cover plate portion 232. During installation, the reset spring 24 can be slidably inserted into the spring clip retaining clip 2321, and the spring clip anti-reverse protrusion 2322 can pass over the hole wall of the anti-reverse hole 241 and enter the anti-reverse hole 241.

[0059] In one specific implementation, the handle 231 has a spring-loaded limiting groove 2311. The spring-loaded limiting groove 2311 aligns with the end of the reset spring 24. When the suction pipe begins to be inserted into the dust collection inlet 221 and lifts the cover 232, the end of the reset spring 24 enters the spring-loaded limiting groove 2311, facilitating the insertion of the suction pipe. When the cover 232 is rotated at a large angle, the end of the reset spring 24 abuts against the bottom of the spring-loaded limiting groove 2311, at which point the reset spring 24 performs a resetting function. Similarly, the handle 231 also functions as a plastic spring, assisting in the resetting of the cover 232.

[0060] In one specific implementation, the dust cover 23 and the clamping plate 21 are integrally formed. The cover portion 232 is connected to the clamping plate 21 via the handle portion 231. The dust cover 23 is folded and fitted onto the clamping plate 21. The dust cover 23 and the clamping plate 21 can be formed in one step using a single mold, thus improving processing efficiency.

[0061] In one specific implementation, a positioning buckle 211 is formed on the card plate 21. The handle 231 is fixed to the card plate 21 by the positioning buckle 211.

[0062] In one specific implementation, the card plate 21 is molded with multiple diameter-adjusting ribs 212. The sealing ring 22 is then molded to enclose the diameter-adjusting ribs 212. The processing method of the sealing ring 22 improves the reliability and stability of the connection. The diameter-adjusting ribs 212 provide support for the sealing ring 22 and also act as a plastic spring. Through the design of the sealing ring 22 and the diameter-adjusting ribs 212, it can accommodate various suction pipes of different diameters; therefore, the dust collection bag 100 can also be called a variable-diameter dust collection bag.

[0063] like Figures 8 to 21 As shown, in the second embodiment of this utility model, a dust collection bag 100a includes: a bag body 10a and a connecting structure 20a. The connecting structure 20a is used to connect with a vacuum suction pipe. The connecting structure 20a is fixed to the bag body 10a. The connecting structure 20a is provided with a dust collection inlet 221a. Specifically, the connecting structure 20a includes: a retaining plate 21a and a sealing ring 22a with a dust collection inlet 221a. The sealing ring 22a is disposed on the retaining plate 21a. The retaining plate 21a is molded with multiple diameter-adjusting ribs 212a. The sealing ring 22a is further molded to wrap around the diameter-adjusting ribs 212a. The diameter-adjusting ribs 212a provide support for the sealing ring 22a and also act as a plastic spring. By using the diameter-adjusting ribs 212a to support the sealing ring 22a, it can adapt to various vacuum suction pipes of different diameters; therefore, the dust collection bag 100a can also be called a variable-diameter dust collection bag.

[0064] A raised ring structure 213a is formed on the side of the card plate 21a facing the bag body 10a. The raised ring structure 213a surrounds the sealing ring 22a. The raised ring structure 213a is fixed to the bag body 10a. Specifically, the raised ring structure 213a is fixed to the bag body 10a by ultrasonic heat fusion welding. More specifically, the raised ring structure 213a is provided with multiple raised points for ultrasonic heat fusion welding. As an optional embodiment, the raised ring structure is glued to the bag body.

[0065] Figures 8 to 21 The second embodiment shown is similar to Figures 1 to 7The difference between the first embodiment and the second embodiment is that the second embodiment does not have the dust cover and reset spring provided in the first embodiment. Furthermore, the second embodiment adds a discharge port and a sealing clamp to close the discharge port, therefore the dust bag 100a can also be called a drawstring clamp dust bag.

[0066] Specifically, such as Figures 8 to 21 As shown, the bag body 10a has a discharge port for pouring out impurities. A sealing clip 30a is fixed to the bag body 10a. The sealing clip 30a includes a base clip 31a and a cover clip 32a. The base clip 31a and the cover clip 32a are respectively fixed to the bag body 10a on both sides of the discharge port.

One of the base body 311a and the cover body 321a has a plurality of insertion holes 3211a. The other of the base body 311a and the cover body 321a has a plurality of insertion posts 3111a. The insertion posts 3111a are detachably inserted into the insertion holes 3211a, thereby connecting the base body 311a and the cover body 321a into a single unit, clamping the pouring port from both sides.

[0068] In one specific implementation, the bag body 10a is folded inward at the position held by the cap clamp to form a folded layer 11a; the insert 3111a passes through the folded layer 11a to prevent the folded layer 11a of the bag body 10a from expanding due to suction or being torn open, causing leakage of impurities inside the bag body 10a. The folded layer 11a increases the size of the pouring port, facilitating material pouring. Specifically, a hole can be pre-machined at the folded layer 11a to facilitate the passage of the insert 3111a.

[0069] In one specific embodiment, the base clip 31a further includes a base end 312a. The cover clip 32a further includes a cover end 322a. The base end 312a and the base body 311a are integrally formed. The cover end 322a and the cover body 321a are integrally formed. The thickness at the connection between the base end 312a and the base body 311a is narrowed to allow the base body 311a to bend relative to the base end 312a. The thickness at the connection between the cover end 322a and the cover body 321a is narrowed to allow the cover body 321a to bend relative to the cover end 322a. The base end 312a, the cover end 322a, and the bag body 10a are fixed as a whole.

[0070] In one specific embodiment, the base clip 31a further includes a lever portion 313a for a user to operate.
