Description

Technical Field

[0001] This utility model belongs to the field of backpack technology, and in particular to a double-shoulder bag. Background Technology

[0002] In existing backpack designs, to improve carrying comfort, a breathable structure is usually incorporated into the back of the backpack to reduce stuffiness caused by prolonged use. Traditional breathable structures typically use rigid support materials such as plastic panels, metal frames, or high-density foam to create gaps and airflow channels between the back and the main body of the backpack, allowing airflow from a fan to pass through these channels. While this type of structure can optimize airflow to some extent, its relatively rigid materials can easily cause pressure on the back when the user wears the backpack for extended periods or carries heavy loads, leading to fatigue and discomfort. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a backpack that has...

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A backpack, comprising:

[0006] Package body;

[0007] A cushion is provided on the back of the main body of the bag and forms a gap between it and the back of the main body. The cushion is made of a honeycomb support and a mesh fabric.

[0008] A plurality of air guide tubes are arranged within the interval and extend from top to bottom. Each air guide tube has a channel and is provided with a plurality of communication holes communicating with the channel.

[0009] A worm gear blower is located at the bottom of the main body of the package, and the outlets of all air guide pipes are aligned with the air inlet of the worm gear blower.

[0010] In the aforementioned backpack, a housing is provided at the bottom of the main body of the backpack, the worm gear fan is installed inside the housing, and an air outlet is provided on the housing.

[0011] In the aforementioned backpack, the bottom of the housing is provided with several support feet.

[0012] In the aforementioned backpack, a directional pipe is installed at the air inlet of the worm gear fan, and several insertion holes are opened on the directional pipe, into which the lower end of the air guide pipe is inserted.

[0013] In the aforementioned backpack, the worm gear fan is equipped with a USB connector, which is used to connect to a power bank.

[0014] In the aforementioned backpack, the honeycomb support is made of silicone.

[0015] In the aforementioned backpack, the mesh fabric is made of any one of polyester fiber, nylon, or cotton linen.

[0016] In the aforementioned backpack, there is a gap between adjacent air tubes.

[0017] In the aforementioned backpack, the axis of the communication port forms an angle with the cushion, the angle being between 0 and 45°.

[0018] Compared with the prior art, this application has the following advantages:

[0019] In this application, when the worm gear fan starts running, the fan generates suction, which draws the air in the compartment from the air inlet of the air guide pipe. Since the air guide pipe is arranged and extends from top to bottom in the compartment and has several exchange holes that communicate with the channel, the air in the upper part of the compartment will enter the air guide pipe channel through the exchange holes, flow down along the air guide pipe, and finally be drawn in and discharged by the worm gear fan, continuously carrying away the hot air in the compartment between the backrest and the back of the main body of the bag.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, a backpack includes: a main body 2, a backrest 3, several air ducts 4, and a worm gear fan 5. The backrest 3 is located on the back of the main body 2, forming a gap 6 between it and the back of the main body 2. The backrest 3 is made of a honeycomb support 31 and a mesh fabric 32. The air ducts 4 are located within the gap 6 and extend from top to bottom. The air ducts 4 have channels and several communication holes 41 connected to the channels. The worm gear fan 5 is located at the bottom of the main body 2, and the outlets 42 of all the air ducts 4 are aligned with the air inlets 51 of the worm gear fan 5.

[0033] In this application, when the worm gear fan 5 starts running, the fan generates suction, which draws the air in the interval 6 into the air inlet 51 of the air guide pipe 4. Since the air guide pipe 4 is arranged and extends from top to bottom in the interval 6 and has several communication holes 41 connected to the channel, the air in the upper part of the interval 6 will enter the channel of the air guide pipe 4 through the communication holes 41, flow downward along the air guide pipe 4, and finally be drawn in and discharged by the worm gear fan 5, continuously carrying away the hot air in the back interval 6 of the cushion 3 and the main body 2.

[0034] The backrest cushion 3 is made of honeycomb support 31 and mesh fabric 32. The honeycomb support 31 forms numerous tiny air circulation spaces, and the mesh fabric 32 facilitates air in and out. Combined with the air circulation formed by the air duct 4 and the worm gear fan 5, it greatly improves the breathability of the back of the backpack, effectively reducing the stuffiness caused by prolonged contact with the backpack and keeping the back dry and comfortable. Compared with traditional breathable structures that use hard support materials, the honeycomb support 31 and mesh fabric 32 of this backpack backrest cushion 3 are relatively soft, which can reduce the pressure on the user's back.

[0035] Specifically, the bottom of the main body 2 is provided with a housing 7, the worm gear fan 5 is installed inside the housing 7, and the housing 7 is provided with an air outlet 71.

[0036] The housing 7 provides physical protection for the worm gear fan 5, preventing damage to the fan from collisions, friction, or external pressure during daily use, thus extending the fan's service life and ensuring stable operation of the ventilation function.

[0037] Specifically, the bottom of the housing 7 is provided with several support feet 72.

[0038] When the backpack is placed on the ground, the support feet 72 separate the housing 7 from the ground, preventing it from directly contacting the rough ground and thus better protecting the internal worm gear fan 5.

[0039] Specifically, a diverting pipe 52 is installed at the air inlet 51 of the worm gear blower 5. Several insertion holes 521 are opened on the diverting pipe 52, and the lower end of the air guide pipe 4 is inserted into the insertion holes 521.

[0040] The lower end of the air duct 4 is inserted into the insertion hole 521 of the diverting tube 52 to form a tight connection. This connection method can effectively prevent the air duct 4 from separating from the air inlet 51 of the worm gear fan 5 during daily use due to backpack shaking, squeezing or user movement, ensuring the stability and integrity of the air flow path.

[0041] Specifically, the worm gear fan 5 is equipped with a USB connector, which is used to connect to a power bank.

[0042] When users are out and about, they can easily power the worm gear fan 5 using a power bank via a USB connector.

[0043] Specifically, the honeycomb support 31 is made of silicone.

[0044] Silicone material has good flexibility, so it will not cause pressure due to the hard material during long-term carrying, effectively distributing the pressure of the backpack on the back.

[0045] Specifically, the mesh fabric 32 is woven from any one of polyester fiber, nylon, or cotton linen.

[0046] Specifically, there is a spacing of 43 between adjacent air ducts 4.

[0047] Compared to closely spaced or unspaced air ducts 4, an appropriate spacing 43 can reduce the number of air ducts 4 used, thereby reducing material costs and lightening the overall weight of the backpack while still meeting ventilation requirements.

[0048] Specifically, the axis of the AC hole 41 forms an angle α with the cushion 3, and the angle α is between 0 and 45°.

[0049] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0050] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
