[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1-7 This utility model provides a dust collection device for use in products such as mite removers or vacuum cleaners to collect dust sucked up by the product, and for easy cleaning or replacement. The dust collection device includes a housing 1 and a dust bag 2. The housing 1 is used to connect to an external device (mite remover or vacuum cleaner, etc.), and the dust bag 2 is used to be placed inside the housing 1 to collect dust or debris sucked into the housing 1. The dust bag 2 is reusable or replaceable, making it convenient for users to clean the product.

[0028] The outer casing 1 has a cavity for accommodating the dust collection bag 2. To achieve dust collection, the outer casing 1 has an air inlet 11 communicating with the cavity and an installation port 12. To generate airflow for dust collection, the installation port 12 is connected to an external suction device. The suction force of the external suction device generates airflow that enters the cavity through the air inlet 11, thereby drawing external debris or dust into the dust collection device. For easy cleaning, a dust collection bag 2 is provided in the outer casing 1, and the dust collection bag 2 is located inside the cavity. The dust collection bag 2 has a dust collection chamber for holding debris or dust.

[0029] The dust collection bag 2 is equipped with a dust collection port 21, which corresponds to the air inlet 11 of the outer casing 1. The dust collection bag 2 has an internal dust collection chamber that effectively collects dust while preventing it from leaking to the outside. Furthermore, the bag wall of the dust collection bag 2 has several fine air vents to prevent impurities, debris, or dust from passing through. Connected to the suction device via the outer casing 1, the gas passes through the air inlet 11. Because the dust collection port 21 corresponds to the air inlet 11, the gas carries impurities into the dust collection bag 2. After flowing through the integrated chamber, the gas exits through the air vents. These air vents not only ensure smooth airflow but also effectively enhance the filtration effect of the dust collection bag 2.

[0030] To further improve the sealing of the dust collection device and prevent dust from overflowing again when not in use, a baffle 3 is installed at the dust collection port 21. When the external suction device is activated, airflow enters the dust collection device through the air inlet 11, and the force of the airflow blows open the baffle 3. Its main function is to seal the dust collection port 21 when the dust collection device is not in use, thereby preventing dust inside the dust collection bag 2 from overflowing again due to airflow or external disturbances. After the baffle 3 is blown open, airflow is smooth, and dust is effectively sucked into the dust collection bag 2.

[0031] Dust is collected via dust bag 2, and users can easily replace the cleaned dust bag 2 without worrying about leakage or contamination during the replacement process. The baffle 3 ensures that the dust inside the dust bag 2 will not overflow again when the device is not in use, thereby reducing the risk of dust contamination. The way the baffle 3 can be blown open allows for smoother airflow guidance and a more obvious dust collection effect.

[0032] Furthermore, the cross-sectional area of ​​the dust collection port 21 is larger than that of the air inlet 11, ensuring that the dust collection device can fully collect the dust brought in by the air inlet 11, avoiding problems such as excessive airflow resistance or uneven dust accumulation caused by the small area of ​​the dust collection port 21. Since the cross-sectional area of ​​the dust collection port 21 is larger than that of the air inlet 11, the air inlet 11 is located within the range of the dust collection port 21. The function of the air inlet 11 is to draw in all contents entering through the airflow generated by the external suction device, thus drawing air and dust into the dust collection chamber. The larger area of ​​the dust collection port 21 also effectively increases the amount of dust collected, ensuring that the dust can fully enter the dust collection bag 2.

[0033] To ensure dust can be collected into the integrated cavity, a precision sealing element 41 is provided between the dust collection port 21 and the air inlet 11 to ensure the airtightness between the air inlet 11 and the dust collection port 21, thereby effectively preventing dust from leaking into the housing 1 or the external environment through any gaps. The sealing element 41 is located at the outermost edge of the dust collection port 21 and abuts against the housing 1. In this embodiment of the invention, the sealing element 41 can be located on the side of the fixing member 4 away from the air inlet 11. As mentioned above, the air inlet 11 is within the range of the dust collection port 21, so the sealing element 41 also surrounds the outer periphery of the air inlet 11, preventing dust from leaking from the connection between the air inlet 11 and the dust collection port 21 during the suction process, thus improving the safety, reliability, and user experience of the dust collection device.

[0034] To improve the stability of the dust collection bag 2, a fixing member 4 is specially designed on the dust collection bag 2, and the dust collection port 21 is opened on the fixing member 4. The fixing member 4 securely fixes the dust collection bag 2 inside the device through a snap-fit ​​design with the outer shell 1. This ensures that the dust collection bag 2 will not move or loosen due to vibration or airflow during use, and at the same time ensures that the air inlet 11 and the dust collection bag 2 are properly aligned, thereby achieving the best dust collection effect.

[0035] In this embodiment of the utility model, the fixing member 4 is a fixing plate, and the fixing plate is adapted to the contour of the outer shell 1. It can be set on the inner side of the outer shell 1 and connected to the inner side wall of the outer shell 1 to ensure that the dust collection port 21 of the dust collection bag 2 is connected to the air inlet 11.

[0036] Furthermore, the inner wall of the outer casing 1 is provided with a guide structure 13 that is adapted to the fixing member 4. This structure assists the fixing member 4 in smoothly entering and securely installing itself in the receiving cavity inside the outer casing 1, thereby ensuring the stable fixing and sealing effect of the dust collection bag 2. The shape and size of the guide structure 13 are set according to the size and shape of the fixing member 4. When the fixing member 4 enters the receiving cavity, the guide structure 13 provides a clear guiding channel for it. Through the guiding action, the fixing member 4 can move precisely along the path of the guide structure 13, thereby avoiding errors or misalignment during installation.

[0037] To facilitate the installation of the fixing component 4, the outer shell 1 adopts a columnar structure with an installation port 12 on one end face. The dust bag 2 enters the receiving cavity of the outer shell 1 through the installation port 12, facilitating the installation and replacement of the dust bag 2. Simultaneously, the installation port 12 can also be connected to an external suction device, thus leaving only one air inlet 11 in the receiving cavity for easy suction. The guide structure 13 consists of two protruding strips 131 extending along the direction of the columnar outer shell 1. The two protruding strips 131 are arranged side-by-side and spaced apart, forming a guide channel. The width of the guide channel is precisely suited to the size of the fixing component 4, specifically designed to guide the sliding of the fixing component 4. Because the columnar structure ensures that the outer periphery extends in one direction, ensuring that the protruding strips 131 are only protruding strips 131, the fixing component 4 can smoothly enter the receiving cavity of the outer shell 1 along a predetermined path, while preventing the fixing component 4 from shifting left or right or becoming misaligned due to free movement during installation. When replacing or cleaning the dust bag 2, the user can easily remove the fastener 4 from the guide channel of the protrusion 131 without worrying about the fastener 4 getting stuck or being mispositioned.

[0038] In addition, to ensure that the fastener 4 is securely attached to the inner wall of the outer casing 1 during installation and to guarantee a tight seal between the air inlet 11 and the dust collection port 21, two protrusions 131 are provided with snap-fit ​​ends 132 on the side facing the receiving cavity. The snap-fit ​​ends 132 on the outer casing 1 extend along the opposite side of the two protrusions 131, and are positioned opposite to the inner wall of the outer casing 1, forming a limiting structure. The fastener 4 is constrained between the snap-fit ​​ends 132 and the inner wall of the outer casing 1, ensuring a tight fit between the fastener 4 and the inner wall of the outer casing 1, thereby ensuring the sealing effect of the dust collection bag 2 and the stability of the equipment. Through the setting of the snap-fit ​​ends 132, the guide structure 13 can simultaneously play the role of guiding and limiting when the fastener 4 slides into the receiving groove. The installation process of the dust collection device becomes simpler, and the fastener 4 will not loosen or fall off due to external force or vibration.

[0039] Preferably, a limiting member 14 is also provided on the inner sidewall of the outer casing 1 to provide precise positioning and restriction for the fixing member 4, ensuring that the fixing member 4 can be firmly held in the predetermined position during installation. Specifically, the limiting member 14 is located near the end of the outer casing 1 away from the mounting port 12, that is, near the bottom of the receiving cavity. When the fixing member 4 slides into the mounting port 12 until it contacts the limiting member 14, the limiting member 14 stops the fixing member 4 from sliding further, and the fixing member 4 is accurately limited to the correct installation position, so that the dust collection port 21 and the air inlet 11 can be precisely aligned. When installing the dust collection device, the user only needs to install the fixing member 4 through the guide structure 13 and slide it until it abuts against the limiting member 14 to easily fix it in place. This ensures the correct installation of the device, making the installation, use and maintenance of the dust collection device more efficient, convenient and reliable.

[0040] To ensure the effectiveness of the shielding component 3, it is positioned on the side of the fixing component 4 near the dust collection chamber. One end of the shielding component 3 is securely connected to the fixing component 4, while the other end is freely suspended, ensuring that it can smoothly cover the dust collection port 21 during dust collection. Structurally, the shielding component 3 is made of flexible material, allowing it to change position with airflow variations to adapt to different working conditions. Alternatively, the shielding component 3 can also be mounted on the fixing component 4 using flexible or elastic material. When subjected to external force, the shielding component 3 can be displaced through the flexible or elastic material and then return to its covering state.

[0041] Specifically, when the dust collection device starts vacuuming, airflow flows into the dust collection chamber through the dust collection port 21. The shield 3 is blown up by the airflow, thereby opening the dust collection port 21 and ensuring that dust and airflow can smoothly enter the dust collection chamber. When the dust collection device stops working or ceases vacuuming, the flexible shield 3 automatically returns to its original position, covering the dust collection port 21 again. When cleaning the equipment or replacing the dust bag 2, users do not need to disassemble complex components. The shield 3 automatically covers the dust collection port 21, preventing dust and other impurities from being discharged or flowing back, making the equipment not only more efficient and cleaner, but also easier to maintain and service.

[0042] Furthermore, to facilitate user replacement of the dust collection bag 2, a handle 22 is provided on the outside of the dust collection bag 2 for easy handling. The handle 22 is located on the side of the dust collection bag 2 near the installation opening 12 when it is installed. Its position allows the user to avoid touching the internal area of ​​the dust collection bag 2, thereby avoiding direct contact with dust and other debris and reducing potential hygiene risks.
