Description

Technical Field

[0001] This utility model relates to a three-dimensional dust collection bag with airflow guidance, which is applicable to the field of air filtration technology. Background Technology

[0002] Dust bags are containers used to collect dust and foreign objects, and are widely used in various vacuum cleaners. Most existing dust bags are made by sewing the edges of two non-woven fabric pieces together, and attaching a clip at the bag opening to secure it to the vacuum cleaner. In use, the dust bag is folded flat and placed into the designated space in the device, and the clip connects the bag opening to the vacuum cleaner's dust collection port. However, because the non-woven fabric of the dust bag is a flexible and breathable material, and the bag is folded within the vacuum cleaner, when airflow carrying dust enters the bag from the collection port, the airflow dissipates from various parts of the bag, preventing the generated air pressure from effectively opening the bag. This causes dust to accumulate at the bag opening, resulting in uneven distribution. This not only affects the efficient use of the dust bag but also obstructs subsequent airflow, impacting the vacuum cleaner's efficiency and effectiveness. On the other hand, after the airflow is blown into the dust collection bag from the dust collection port, it will concentrate on impacting the area inside the dust collection bag opposite to the dust collection port. Over time, a large amount of dust will accumulate at the point of impact, which will increase the wind resistance at this point. This will not only further affect the dust collection effect, but also cause damage to this area under the impact of the airflow, affecting the service life of the dust collection bag. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention proposes a three-dimensional dust collection bag with flow guidance.

[0004] The present invention employs a three-dimensional dust collection bag with a flow-guiding mechanism, comprising a first bag face with an air inlet at its center, a second bag face positioned behind and parallel to the first bag face, and a third bag face positioned between the first and second bag faces and sealed to the edges of both the first and second bag faces. The first, second, and third bag faces together enclose a dust collection space for containing dust. The first bag face is axially symmetrical about a centerline passing through its center, and the dimension of one side of the first bag face intersecting the centerline is smaller than the dimension of the opposite side. The shape and orientation of the second bag face are the same as those of the first bag face. The three-dimensional dust collection bag also includes a flow guide component positioned within the dust collection space and fixed to the surface of the second bag face for guiding airflow. The flow guide component is made of an airtight material and is located directly behind the air inlet, and its dimension is larger than that of the air inlet. When in use, fold the 3D dust collection bag into a flat state and put it into the vacuum cleaner. In this state, the third bag face is folded inward from the middle, the first bag face is in contact with the second bag face, and the dust collection space is in a compressed state. The dust collection bag is a three-dimensional structure composed of a first bag face, a second bag face, and a third bag face. A guide vane on the inner side of the second bag face ensures that when airflow enters the dust collection bag from the inlet, it impacts the guide vane. Because the guide vane is made of an impermeable material, the airflow generates pressure on it, pushing the second bag face away from the first bag face and unfolding the third bag face from its folded state. This fully releases the dust collection space from its compressed state, preventing obstruction of the continuously blowing airflow, ensuring suction efficiency and effectiveness, and fully utilizing the dust collection space within the bag, avoiding frequent cleaning and replacement, further improving dust collection efficiency. Subsequently, the airflow carrying dust continuously impacts the guide vane, and after impacting its surface, the dust disperses outwards along the guide vane's surface, evenly dispersing the dust within the dust collection space. This not only eliminates the negative impact of dust accumulation in a specific area of ​​the dust collection bag on suction performance but also prevents damage to the bag body from airflow impact, extending the dust collection bag's lifespan.

[0005] Furthermore, the flow guide is configured as an arch shape that protrudes forward from the center of the second bag surface. Specifically, the center can be the central part of the flow guide, with the surface of the flow guide gradually arching from the periphery towards the center from back to front; or it can be the central axis of the flow guide that is parallel or perpendicular to the center line of the first bag surface, with the flow guide gradually arching from both sides towards the central axis from back to front. The arched flow guide can further improve the dispersion and guidance of airflow, thereby ensuring that dust can be evenly diffused.

[0006] Furthermore, the airflow guide is made of release paper. The release paper is lightweight, easy to stick, and has a smooth surface, which can prevent excessive weight from pulling on the non-woven fabric of the dust collection bag, ensuring that the airflow can open the dust collection bag and prevent it from collapsing. It also makes it easy to connect and fix the release paper inside the dust collection bag. At the same time, the release paper does not easily stick to dust, which can prevent dust from sticking and accumulating on the release paper and ensure the dust collection effect of the dust collection bag.

[0007] Furthermore, both the first and second bag faces are trapezoidal, and the connection between the third bag face and the first and second bag faces is ultrasonically welded. By welding and fixing the edges of the first and third bag faces, as well as the edges of the second and third bag faces, not only is the sealing effect of the dust collection bag guaranteed, but the non-woven fabric after ultrasonic welding also has a certain degree of hardness, which can serve as the skeleton of the dust collection bag. Combined with the trapezoidal first and second bag faces, the structural strength and stability of the three-dimensional dust collection bag can be improved, preventing collapse.

[0008] Furthermore, the shape of the guide element is the same as that of the second bag surface, which improves the guiding effect on the airflow and ensures that the airflow can carry the dust to be evenly distributed in the dust collection space.

[0009] Furthermore, the first, second, and third bag surfaces are all made of non-woven filter paper mixed with antibacterial and antifungal agents. Specifically, the antibacterial and antifungal agents are antibacterial agents containing silver ions, zinc ions, or copper ions, which can effectively inhibit the growth of microorganisms in the dust collection bag, prevent odors, avoid secondary pollution, and ensure hygiene and user health.

[0010] Furthermore, the inner sides of the first, second, and third bag surfaces are all coated with an antibacterial and anti-mildew coating. Specifically, the antibacterial and anti-mildew coating is an antibacterial coating composed of silver ions, zinc ions, or copper ions, which can effectively inhibit the growth of microorganisms inside the dust collection bag, prevent odors, avoid secondary pollution, and ensure hygiene and user health.

[0011] Furthermore, the first, second, and third bag surfaces are all made of multi-layer composite nonwoven fabric, and at least one layer of the multi-layer composite nonwoven fabric contains an antibacterial and antifungal agent. Specifically, the antibacterial and antifungal agent is an antibacterial agent containing silver ions, zinc ions, or copper ions, which can effectively inhibit the growth of microorganisms in the dust collection bag, prevent odors, avoid secondary pollution, and ensure hygiene and user health.

[0012] Furthermore, the three-dimensional dust collection bag also includes a card plate set on the front of the first bag surface for connecting with the dust collection equipment, which facilitates disassembly and assembly and improves the convenience of cleaning or replacing the dust collection bag.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The airflow-guided three-dimensional dust collection bag of this invention has a simple structure and is easy to process. The dust collection bag is formed by a first bag surface, a second bag surface, and a third bag surface. At the same time, the airflow is guided by the airflow guide, which not only improves the utilization efficiency of the space inside the dust collection bag, avoids obstruction of airflow and frequent dust bag replacement, and ensures dust collection effect and efficiency, but also allows the airflow to be dispersed in all directions under the action of the airflow guide after entering the dust collection bag, so that the dust is evenly distributed in the dust collection space, avoiding damage to a certain area of ​​the dust collection bag under long-term airflow impact, further improving the dust collection effect, and at the same time extending the service life of the dust collection bag.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] In the description of this utility model, it should be noted that the terms "front" and "rear" are defined according to the airflow direction after the dust collection bag is normally installed. Specifically, when the dust collection bag is normally installed in the dust collection equipment, the direction in which the airflow enters the dust collection bag is "front," and vice versa is "rear." The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Reference Appendix Figure 1-5 The three-dimensional dust collection bag with airflow guidance in this embodiment includes a first bag surface 1 with an air inlet 11 in the center, a second bag surface 2 located behind the first bag surface 1 and parallel to the first bag surface 1, and a third bag surface 3 located between the first bag surface 1 and the second bag surface 2 and sealed to the edges of the first bag surface 1 and the second bag surface 2 respectively. The first bag surface 1, the second bag surface 2 and the third bag surface 3 together enclose a dust collection space 4 for containing dust. The first bag surface 1 is axially symmetrical about the center line passing through its center, and the size of the side of the first bag surface 1 that intersects the center line is smaller than the size of the other side opposite to that side. The shape and direction of the second bag surface 2 are the same as those of the first bag surface 1. The three-dimensional dust collection bag also includes a guide member 5 for guiding airflow, which is disposed in the dust collection space 4 and fixed to the surface of the second bag surface 2. The guide member 5 is made of an airtight material and is located directly behind the air inlet 11, and the size of the guide member 5 is larger than the size of the air inlet 11. When in use, the three-dimensional dust collection bag is folded into a flat state and inserted into the vacuum cleaner. In this state, the third bag surface 3 is folded inward from the middle, the first bag surface 1 is attached to the second bag surface 2, and the dust collection space 4 is in a compressed state. The dust collection bag is formed by the first bag face 1, the second bag face 2, and the third bag face 3, creating a three-dimensional shape. A guide 5 is located inside the second bag face 2. When airflow enters the dust collection bag from the air inlet, it impacts the guide 5. Because the guide 5 is made of an airtight material, the airflow generates a certain wind pressure on it, pushing the second bag face 2 away from the first bag face 1 and causing the third bag face 3 to unfold from its folded state. This fully releases the dust collection space 4 from its compressed state, preventing obstruction of the continuously blowing airflow, ensuring dust collection efficiency and effect, and fully utilizing the dust collection space within the dust collection bag, avoiding frequent cleaning and replacement, further improving dust collection efficiency. Subsequently, the airflow carrying dust continuously impacts the guide 5, and after impacting its surface, the dust disperses outwards along the guide 5, evenly dispersing the dust in the dust collection space. This not only eliminates the adverse effects of dust accumulation in a certain area of ​​the dust collection bag on the dust collection effect but also avoids damage to the bag body from airflow impact, extending the service life of the dust collection bag.

[0018] In a more preferred embodiment, the guide member 5 is configured as an arch shape that protrudes forward from the surface of the second bag surface 2 in the middle. Specifically, the middle part here can be the central part of the guide member 5, and the surface of the guide member 5 gradually arches from the periphery to the center from back to front (as shown in the attached figure). Figure 5 (As shown); or it can be the central axis of the guide member 5, parallel or perpendicular to the center line of the first bag surface, with the guide member 5 gradually arching from the back to the front from both sides towards the central axis (as shown in the attached figure). Figure 3 Or attached Figure 4 As shown, the arched guide can further enhance the dispersion and guidance of airflow, thereby ensuring that dust can be evenly dispersed.

[0019] In a more preferred embodiment, the guide element 5 is configured as release paper (as shown in the attached document). Figure 2 As shown, the release paper is lightweight, easy to stick, and has a smooth surface, which can prevent excessive weight from pulling on the non-woven fabric of the dust collection bag, ensuring that the airflow can open the dust collection bag and prevent it from collapsing; it is also convenient to connect and fix the release paper inside the dust collection bag, and the release paper does not easily stick to dust, which can prevent dust from sticking and accumulating on the release paper and ensuring the dust collection effect of the dust collection bag.

[0020] In a more preferred embodiment, both the first bag face 1 and the second bag face 2 are trapezoidal, and the connection between the third bag face 3 and the first bag face 1 and the second bag face 2 is ultrasonically welded. By welding and fixing the edges of the first bag face 1 and the third bag face 3, as well as the edges of the second bag face 2 and the third bag face 3, not only is the sealing effect of the dust collection bag guaranteed, but the non-woven fabric after ultrasonic welding also has a certain degree of hardness, which can serve as the skeleton of the dust collection bag. Combined with the trapezoidal first bag face 1 and the second bag face 2, the structural strength and structural stability of the three-dimensional dust collection bag can be improved, and collapse can be prevented.

[0021] In a more preferred embodiment, the shape of the guide 5 is the same as that of the second bag surface 2, which improves the guiding effect on the airflow and ensures that the airflow can carry the dust to be evenly distributed in the dust collection space 4.

[0022] In a more preferred embodiment, the first bag surface 1, the second bag surface 2, and the third bag surface 3 are all made of non-woven filter paper mixed with antibacterial and antifungal agents.

[0023] In a more preferred embodiment, the inner sides of the first bag surface 1, the second bag surface 2, and the third bag surface 3 are all coated with an antibacterial and anti-mildew coating. Specifically, the antibacterial and anti-mildew coating is an antibacterial coating composed of silver ions, zinc ions, or copper ions, which can effectively inhibit the growth of microorganisms in the dust collection bag, prevent the generation of odors, avoid secondary pollution, and protect hygiene and user health.

[0024] In a more preferred embodiment, the first bag surface 1, the second bag surface 2, and the third bag surface 3 are all made of multi-layer composite non-woven fabric, and at least one layer of the multi-layer composite non-woven fabric contains an antibacterial and antifungal agent. Specifically, the antibacterial and antifungal agent is an antibacterial agent containing silver ions, zinc ions, or copper ions, which can effectively inhibit the growth of microorganisms in the dust collection bag, prevent odors, avoid secondary pollution, and protect hygiene and user health.

[0025] In a more preferred embodiment, the three-dimensional dust collection bag further includes a card plate 6 disposed on the front of the first bag surface 1 for connection with the dust collection equipment, which facilitates disassembly and assembly and improves the convenience of cleaning or replacing the dust collection bag.

[0026] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The airflow-guided three-dimensional dust collection bag of this invention has a simple structure and is easy to process. The dust collection bag is formed by a first bag surface, a second bag surface, and a third bag surface. At the same time, the airflow is guided by the airflow guide, which not only improves the utilization efficiency of the space inside the dust collection bag, avoids obstruction of airflow and frequent dust bag replacement, and ensures dust collection effect and efficiency, but also allows the airflow to be dispersed in all directions under the action of the airflow guide after entering the dust collection bag, so that the dust is evenly distributed in the dust collection space, avoiding damage to a certain area of ​​the dust collection bag under long-term airflow impact, further improving the dust collection effect, and at the same time extending the service life of the dust collection bag.
