Technical Field

[0001] This utility model relates to the field of bag technology, specifically a multi-functional bag. Background Technology

[0002] A bag is a container used to carry personal items. It is usually made of fabric, leather, synthetic materials or other durable materials. It comes in a variety of different forms and functions to meet different occasions and needs. The design of a bag usually includes one or more storage spaces, shoulder straps or handles to facilitate carrying and storing items. Depending on the function and purpose, there are different types of bags.

[0003] Traditional bags primarily focus on the storage and carrying of items. Their design often prioritizes capacity allocation, appearance, and carrying comfort. In hot environments, bags made of sealed or simple mesh fabrics have poor air circulation, which can lead to sweat buildup, causing stuffiness, stickiness, and even bacterial growth, thus reducing user comfort.

[0004] Therefore, a multi-functional bag is proposed to solve the aforementioned technical problem of poor user comfort. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multifunctional bag that offers high comfort and solves the problems of poor air circulation, sweat accumulation during prolonged carrying, and the resulting stuffiness and stickiness.

[0027] 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.

[0028] Example 1:

[0029] Please see Figure 1-3 A multi-functional bag in this embodiment includes a bag body 1, and a cooling component 2 for blowing air onto the user's back is provided on the bag body 1.

[0030] The cooling component 2 includes a PCB control board 201 disposed inside the bag body 1, a drive module 202 disposed on the bag body 1, a rotating shaft 203 connected to the output shaft of the drive module 202, and a fan blade 204 sleeved on the outer periphery of the rotating shaft 203. The PCB control board 201 is electrically connected to the drive module 202.

[0031] The PCB control board 201 serves as the core control unit, integrating and processing signals from various sensors.

[0032] It should be noted that the control unit controls the output shaft of the drive module 202 to rotate, causing the rotating shaft 203 and the fan blade 204 to rotate, thereby achieving airflow cooling for the user's back. The control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0033] When in use, the user uses the main body of the bag 1, the drive module 202 is activated, the output shaft of the drive module 202 starts to rotate, driving the rotating shaft 203 to rotate. The rotation of the rotating shaft 203 drives the fan blades 204 to rotate, blowing air to cool the user's back, effectively reducing the temperature of the user's back, avoiding problems such as stuffiness and sweating caused by carrying for a long time, and improving the user's comfort and user experience when using the bag.

[0034] Example 2

[0035] Please see Figure 4-7In this embodiment, the main body 1 of the bag has several grooves 205 corresponding to the user's back. A grille 206 is detachably connected to the groove 205. The drive module 202 is fixedly installed on the inner wall of the groove 205. The fan blade 204 is located inside the groove 205 and is used to blow air onto the user's back.

[0036] Furthermore, the design of the recess 205 and the removable grille 206 optimizes the airflow channels, enhances heat dissipation efficiency, and facilitates cleaning and maintenance.

[0037] The main body 1 of the bag is also equipped with a storage battery 207. A solar cell 208 is embedded on the outside of the main body 1 of the bag. The solar cell 208 is electrically connected to the storage battery 207, and the storage battery 207 is electrically connected to the drive module 202.

[0038] It should be noted that the solar cell 208 is a common device in the prior art, and will not be described in detail in this embodiment. The solar cell 208 prioritizes power supply to the system, and excess screen energy is stored in the battery 207. When the solar power supply is insufficient, it automatically switches to the battery 207 for power supply.

[0039] A humidity sensor is embedded in the back of the bag body 1 corresponding to the user's back, and the humidity sensor is connected to the PCB control board 201.

[0040] During application, the humidity sensor monitors the humidity changes of the contact surface between the user's back and the main body 1 of the bag in real time. When the humidity sensor detects that the humidity on the back exceeds the threshold, the humidity sensor sends a signal to the PCB control board 201. After receiving the signal, the PCB control board 201 starts the drive module 202. The output shaft of the drive module 202 starts to rotate, which drives the rotating shaft 203 to rotate. The rotation of the rotating shaft 203 drives the fan blade 204 to rotate. The fan blade 204 generates directional airflow. The airflow passes through the optimized groove 205 and grille 206 structure to form uniform back airflow, which reduces the user's back temperature and improves the user's comfort.

[0041] Example 3:

[0042] Please see Figure 8 In this embodiment, the inner wall of the bag body 1 is also embedded with an LED light strip 3, and the inner wall of the bag body 1 is equipped with a photoresistor sensor 4.

[0043] Furthermore, the photoresistor sensor 4 is a common device in the prior art, and will not be described in detail in this application.

[0044] LED light strip 3 is electrically connected to PCB control board 201 and is used to locate items at night.

[0045] LED light strip 3 is electrically connected to battery 207, and photoresistor sensor 4 is signal connected to PCB control board 201.

[0046] It should be added that when the ambient light is insufficient and the main body of the bag 1 is opened, the LED light strip 3 is automatically activated to provide moderate lighting inside the bag. The brightness of the lighting is automatically adjusted according to the ambient light, and the lighting is automatically turned off after the main body of the bag 1 is closed.

[0047] In application, the photoresistor sensor 4 monitors the ambient light intensity in real time. When the photoresistor sensor 4 detects that the ambient light is lower than the set threshold, it sends a signal to the PCB control board 201. The PCB control board 201 turns on the power of the LED light strip 3, and the LED light strip 3 provides lighting inside the bag body 1, making it convenient for users to take out and put in items in dim environments. When the ambient light returns to sufficient levels, the system automatically turns off the LED lighting to save energy.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
