[0022] 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.

[0023] Please see Figure 1-5 A stain-resistant and antibacterial multi-layer non-woven bag includes a bag body 1, with handles 2 installed on both sides of the top of the bag body 1. A filter screen 6 is fixedly connected to the bottom of the inside of the bag body 1. The bag body 1 includes an outermost layer 10, an outer layer 11, an antibacterial layer 12, and an inner layer 13. A sewage pipe 9 is fixedly connected to the outer wall of the bottom of the bag body 1. A sewage discharge component is provided at the bottom of the inside of the bag body 1, which discharges sewage through the sewage pipe 9. The bag body 1 is used to hold items, and the handles 2 make it convenient for users to carry. When water vapor is generated inside the bag due to hot food and condenses into water, the water will pass through the filter screen 6 fixed at the bottom of the inside of the bag body 1 and slide down the slope 7 to the bottom of the bag body 1. At this time, the sewage discharge component is activated. By unscrewing the sealing cap 4, the activated carbon 8 is moved out of the bag body 1, allowing the sewage to be discharged through the sewage discharge pipe 9 fixedly connected to the bottom outer wall of the bag body 1. The filter screen 6, the ramp 7, the sewage discharge pipe 9 and the sewage discharge component work together to construct an effective water vapor discharge mechanism, avoiding the accumulation of water vapor in the bag and causing a humid environment, reducing bacterial growth, maintaining the antibacterial effect of the antibacterial layer 12, preventing the bag body from softening due to moisture, and improving its load-bearing capacity.

[0024] The top inner wall of the bag body 1 is fixedly connected with a Velcro surface 5 and a Velcro hook surface 3; the Velcro surface 5 and the Velcro hook surface 3 on the top inner wall of the bag body 1 constitute a sealing assembly, and the user can close or open the bag opening by attaching or separating the two.

[0025] The sewage discharge assembly also includes a sealing cap 4, activated carbon 8, and a ramp 7. The ramp 7 is fixedly connected to both sides of the bottom inside the bag body 1. The sealing cap 4 is set on both side walls of the bag body 1. The activated carbon 8 is fixedly connected to the side wall of the sealing cap 4 and is located inside the bag body 1. The inner wall of the sealing cap 4 is threadedly connected to the outer wall of the sewage pipe 9. The ramp 7 guides the water accumulated inside the bag to converge at the bottom of the bag body 1. The sealing cap 4 is threadedly connected to the sewage pipe 9. Twisting the sealing cap 4 can control the opening and closing of the sewage pipe 9. The activated carbon 8 is fixed to the side wall of the sealing cap 4 and enters and exits the bag body 1 with the sealing cap 4 to absorb odors inside the bag. The ramp 7 is designed to accelerate the convergence of sewage and improve sewage discharge efficiency. The activated carbon 8 purifies the air inside the bag and creates a good storage environment. The threaded sealing cap 4 has a good sealing effect and prevents odors and sewage leakage.

[0026] The outermost layer 10 is made of polypropylene nonwoven fabric; the outermost layer 11 is made of polyester nonwoven fabric; the antibacterial layer 12 is made of chitosan fiber nonwoven fabric; and the innermost layer 13 is made of viscose needle-punched nonwoven fabric. The outermost layer 10, polypropylene nonwoven fabric, utilizes its water- and oil-repellent properties to resist external stains; the outermost layer 11, polyester nonwoven fabric, enhances the bag's durability with its high strength and abrasion resistance; the antibacterial layer 12, chitosan fiber nonwoven fabric, inhibits bacterial growth; and the innermost layer 13, viscose needle-punched nonwoven fabric, is soft and comfortable, protecting the contents.

[0027] The user can easily carry the non-woven bag by lifting the handles 2 on both sides of the top of the bag body 1. When opening the bag, separate the Velcro side 5 and the Velcro hook side 3 on the inner wall of the top of the bag body 1. When sealing, stick the two together to complete the bag opening sealing operation 2. When holding hot food, water vapor is generated inside the bag and condenses into water. This water passes through the filter 6 at the bottom of the inside of the bag body 1 and slides down the slopes 7 fixed on both sides of the bottom of the inside of the bag body 1 to the bottom of the bag body 1. Then, the user unscrews the sealing caps 4 on both sides of the bag body 1. The sealing caps 4 drive the activated carbon 8 connected to the side wall to move out of the bag body 1, allowing the sewage to be discharged through the drain pipe 9 fixedly connected to the outer wall of the bottom of the bag body 1.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
