Fixing slots, adapted to the sliding rods, are evenly spaced along the length of the sliding frame's sidewall. This invention, by incorporating a sliding frame and slider mechanism, allows users to adjust the length of the handle according to their needs, making it more convenient to use.

[0004] Existing non-woven bags have limited functionality and cannot meet people's growing personalized needs. For example, when shopping, people often need to know the weight of the goods they purchase in order to estimate prices or control the quantity bought. Currently, people usually need to use external electronic scales to weigh the items, which is inconvenient. The above solution, by setting up a sliding frame and slider mechanism, allows users to adjust the length of the carrying straps according to their needs, making it more convenient to use. However, this solution does not take into account that as non-woven bags become more widely used, many people will want to know the quality of the goods they purchase before weighing them at checkout in order to evaluate the price.

[0005] Therefore, it is necessary to provide an intelligent weighing nonwoven bag. Utility Model Content

[0024] Based on this, in order to improve the problem that many people do not know the quality of the goods they buy before weighing and checking out when shopping, and cannot evaluate the price, which causes inconvenience, the embodiments of this application provide the following solutions.

[0025] Please refer to the following: Figure 1 as well as Figure 5 The nonwoven bag body 1 and the weighing mechanism 2 are included. The weighing mechanism 2 includes a pad 21, a pressure sensor 22 and a support plate 23. The pad 21 is bonded to the inside of the nonwoven bag body 1, the pressure sensor 22 is bonded to the pad 21 and the support plate 23 is bonded to the pressure sensor 22.

[0026] With this setup, when using a non-woven bag for shopping, the bag opening is opened, and the items are placed on the support plate 23. The support plate 23 bears the pressure and sends the pressure feedback to the pressure sensor 22. During this process, the pad 21 provides support, allowing the non-woven bag to be weighed whether it is placed on the ground or the user holds the non-woven bag body 1. This makes it convenient for users to keep track of the weight of the goods at any time, so that they can know the quantity of the purchased goods. In some places, such as farmers' markets, users can weigh and check the goods themselves after the merchant has weighed them.

[0027] Optionally, in some embodiments, please also refer to Figure 2 as well as Figure 5 The pad 21 has a placement cavity inside, and a signal processor 3 and a wireless transmitter 4 are bonded inside the placement cavity. The signal processor 3 is electrically connected to the pressure sensor 22, and the signal processor 3 is electrically connected to the wireless transmitter 4.

[0028] With this setup, after the product is placed on the support plate 23, the pressure sensor 22 senses the pressure and converts it into an electrical signal, which is then transmitted to the signal processor 3. The signal processor 3 processes the pressure signal and transmits the relevant information to the wireless transmitter 4. The wireless transmitter 4 can connect to devices such as mobile phones to transmit the relevant information, allowing users to visually view the specific weight data on their phones. The signal processor 3 and the wireless transmitter 4 are integrated into the placement cavity inside the pad plate 21, avoiding the hassle of external devices. The internal bonding ensures a stable connection between electronic components, reducing the risk of loosening or poor contact, maintaining the bag's lightweight and simple design, and ensuring its aesthetic appeal. Users do not need to manually read the weight; the data can be directly sent to smart devices, enhancing the user experience.

[0029] Optionally, in some embodiments, please also refer to Figure 2 The bottom of the nonwoven bag body 1 is fixedly connected with a shock-absorbing pad 6.

[0030] With this design, the shock-absorbing pad 6 can reduce friction between the bottom of the bag and the ground or other surfaces, prevent the bottom of the bag from wearing out too quickly, and extend its service life. In addition, the design of the shock-absorbing pad 6 allows the bottom of the non-woven bag body 1 to be a certain distance from the ground, which can effectively prevent the non-woven bag body 1 from coming into contact with water stains on the ground in some situations, keep the non-woven bag body 1 dry, and prevent mold. At the same time, the shock-absorbing pad 6 usually has anti-slip properties, which allows the bag to be placed stably on different surfaces and reduces the risk of slipping.

[0031] Optionally, in some embodiments, please also refer to Figure 1 as well as Figure 3 A handle 7 is attached to the non-woven bag body 1. A protective cover 8 is fitted onto the handle 7. A snap button 9 and a buckle seat 10 are attached to the protective cover 8. The snap button 9 and the buckle seat 10 are engaged.

[0032] With this design, the protective cover 8 is usually made of soft material, providing a more comfortable feel and reducing pressure and discomfort on the hands. The snap button 9 is simple and easy to use, allowing users to quickly fasten or unfasten it, improving efficiency. After the protective cover 8 is placed on one of the carrying straps 7, the other carrying strap 7 is placed on the protrusion of the protective cover 8, where the snap button 9 is attached. Then, the protrusion is rotated to wrap the other carrying strap 7 around the protective cover 8, while the snap button 9 on the protrusion is engaged with the buckle 10 on the protective cover 8. The protective cover 8 combines the two carrying straps 7 to form a cylinder, which the user can grip to prevent hand injury and improve grip.

[0033] Optionally, in some embodiments, please also refer to Figure 1 as well as Figure 4 The opening of the non-woven bag body 1 is attached with Velcro 11, and the non-woven bag body 1 is also coated with a waterproof layer.

[0034] With this design, the Velcro 11 at the opening of the non-woven bag body 1 makes it easy to open or close the bag at any time, increasing the convenience of operation. After closing the opening of the non-woven bag body 1 with the Velcro 11, it can effectively prevent the items inside the non-woven bag body 1 from spilling out. The non-woven bag body 1 is coated with a waterproof layer, which isolates water from the non-woven bag body 1, reduces the degree of moisture absorption of the non-woven bag body 1, prevents the non-woven bag body 1 from getting damp and moldy, and eventually rots, thus extending the service life of the non-woven bag body 1.

[0035] Optionally, in some embodiments, please also refer to Figures 1-4 A mesh 12 is attached to the non-woven bag body 1.

[0036] With this design, the mesh 12 increases the storage space of the non-woven bag body 1, allowing items to be stored in categories for easy organization and retrieval. Alternatively, items that need to be stored and retrieved at any time, such as drinks, can be stuffed into the mesh 12. The mesh 12 has a certain degree of elasticity, ensuring that the items stuffed into the mesh 12 are fixed in place by the elasticity of the mesh 12.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
