Description

backpack

This creation is related to backpacks; in particular, a backpack with an air pump.

The backpack is a tool for carrying articles. Because it is flexible and convenient, and the weight of the articles carried in the backpack can be dispersed to the shoulder of the user through the shoulder strap, the burden is reduced, so it is widely accepted by the public. Loved and used, whether it is for the general public to work, class, or engage in activities such as mountain climbing, rock climbing, backpacks have become the first choice.

However, backpacks still have their drawbacks. If the user is carrying the backpack for too long, the user's back rests on the backpack for a long time, which not only causes the user's back to be ventilated, but also feels sultry and uncomfortable. In addition, the moisture generated by sweating is easy to accumulate. The back of the person may even cause adverse reactions to the user's skin, such as rashes.

In order to solve the above problems, some manufacturers have a plurality of rib-like convex structures on the back of the backpack to contact the back of the user, in an attempt to allow the sweat on the back of the user to volatilize in the gap between the raised structures, but the heat dissipation effect is affected. The natural flow of air is limited, so the results are not good.

In view of this, the purpose of the present invention is to provide a backpack that includes an air pump that can provide airflow to the back of the user to eliminate the sweat.

In order to achieve the above object, the present invention provides a backpack comprising: a bag body for accommodating articles; at least one strap having two ends disposed on the bag body; an air pump is disposed on the bag body When the user uses the backpack, it is located between the user's back and the bag body; the air pump includes a body having elasticity, wherein the body has a first side portion and a second side portion, and the second portion a side portion is located between the bag body and the first side portion; a gas chamber is formed between the first side portion and the second side portion, and the first side portion is formed with a plurality of connecting the air chamber and the outside The air hole; the body further has a plurality of elastic portions located in the air chamber and connecting the first side portion and the second side portion. .

The effect of the present invention is that the body of the air pump has a flexible, hollow design with a plurality of air holes, so that when the user uses the backpack, the back and the bag body press the body to squeeze the airflow from the body and flow toward the body. The back of the user reaches the sweat that takes away the back of the user. Even if the user walks and moves the backpack for a long time, the back can be kept ventilated, so that the user does not feel stuffy.

In order to more clearly illustrate the novel creations, several preferred embodiments are described in detail with reference to the drawings. Referring to FIG. 1 and FIG. 2, the backpack of the first preferred embodiment of the present invention comprises a bag body 1 for accommodating articles, at least one strap 2, and an air pump.

In this embodiment, the number of the at least one straps 2 is two, and the two ends of the straps 2 are disposed at opposite ends of a back side 1a of the bag body 1 for the user to bear the bag body 1 and use. When the bag body 1 is carried, the back side 1a faces the back of the user.

The bag body 1 includes at least one air permeable bag 1b for placing the air pump, so that the air pump is detachably disposed on the back side 1a of the bag body 1 and is located on the back of the user and the bag when the user uses the backpack. Between body 1. In this embodiment, the backpack has three air permeable bags 1b for three air pumps, but is not limited thereto, the backpack may be provided with only one venting bag 1b, or more venting bags 1b; The shape of each of the air pump and each of the air permeable bags 1b can be adjusted according to the needs of the user.

Referring to FIG. 2, FIG. 3 and FIG. 4a, the air pump comprises a body 10, and the body 10 is made of an elastically deformable material, such as thermoplastic elastomer TPE, silicone rubber, rubber, etc., but not limit.

The body 10 has a substantially flat shape with a first side portion 12 and a second side portion 14 , and the second side portion 14 is located between the back side 1 a of the bag body 1 and the first side portion 12 . A gas chamber 10a is formed between the first side portion 12 and the second side portion 14, and the first side portion 23 is formed with a plurality of air holes 12a communicating with the air chamber 10a and the outside.

The body 10 has a plurality of cylindrical elastic portions 16 located in the air chamber 10a, and the two ends of the elastic portions 16 are respectively connected to the first side portion 12 and the second side portion 14, wherein the elastic portions The diameter of both ends of the 16 is larger than the diameter of the middle of the elastic portions 16.

The above is a description of the various components of the backpack of the first preferred embodiment of the present invention and related positions. I will describe how it is used as follows. When the user is carrying the backpack, the back of the user will be close to the back side 1a of the bag body 1 and sometimes away. Referring to FIG. 4a and FIG. 4b, when the back of the user is relatively close to the back side 1a of the bag body 1, the body 10 is pressed, and the body is deformed from a first state S1 to a second state S2. . At this time, the volume of the air chamber 10a is reduced, so that the air in the air chamber 10a flows out of the air chamber 10a from the air holes 12a, and forms a airflow blown toward the back of the user, thereby achieving the function of taking away sweat from the back of the user. At the same time, the user's back is kept ventilated without being sultry because of carrying a backpack.

4b and 4c, when the back of the user is relatively far away from the back side 1a of the bag body 1, the body 10 is no longer squeezed and returns to the first state from the second state S2. In the state S1, at the same time, the gas around the air hole 12a is sucked into the air chamber 10a from the outside of the air chamber 10a, and the air chamber 10a is again filled with the gas.

The elastic portion 16 is located between the first side portion 12 and the second side portion 14 to provide a spring force for the first side portion 12 and the second side portion 14 to rebound. The second state S2 returns to the first state S1. In addition, the design of the central portion of the elastic portion 16 having a smaller diameter at both ends helps to deform the elastic portion 16 such that when the back of the user is relatively close to the back side 1a of the bag body 1, the first side The portion 12 can be attached to the user along the contour of the back of the user to achieve the pressure of distracting the back of the user.

In order to prevent the air holes 12a from being shielded by the back of the user and affecting the effect of the air pump to push the gas, please refer to FIG. 5a to FIG. 5b, which is the body 20 of the second preferred embodiment of the present invention, and the first preferred embodiment described above. The difference is that the first side portion 22 has a plurality of recessed portions 24 facing away from the second side portion 26, and at least some of the recessed portions 24 respectively have an air hole 22a.

When the back of the user is relatively close to the back side 1a of the bag body 1 and the user presses the first side portion 22, the air holes 22a are still at a distance from the back of the user (ie, the recess portion) The recessed depth D1 of 24 is such as to prevent the air holes 22a from being shielded by the back of the user, so that the air in the air chamber 20a can be smoothly extruded out of the air chamber 20a.

In addition, referring to FIG. 6 and FIG. 7a and FIG. 7b, the air pump of the third preferred embodiment of the present invention, wherein the first side portion 32 of the body 30 has a plurality of recessed portions 34 facing away from the second side portion. 36, and the plurality of recessed communication grooves 32a respectively communicate with the adjacent at least two recess portions 34, and the recess depth D2 of each of the recess portions 34 is larger than the recess depth D3 of the communication groove 32a.

The design of the recessed portion 34 and the connecting grooves 32a can not only reduce the contact area between the back of the user and the first side portion 32, but also reduce the feeling of sultry discomfort on the back of the user; when the body 30 is squeezed, the airflow Since the air holes 32b are extruded through the air chambers 30a, they flow along the communication grooves 32a, and can flow to a region where the back of the user is away from the air holes 32b.

In addition to providing a recess, see the air pump of the fourth preferred embodiment of the present invention shown in FIGS. 8a and 8b, wherein the first side portion 42 of the body 40 has a plurality of protrusions 44 facing away from the second side. The protrusions 44 are respectively located on the axial extension lines of the corresponding elastic portions 48; the air holes 42a are located between the adjacent protrusions 44.

When the body is pressed, the protrusions 44 abut against the back of the user to provide a gap between the air holes 42a and the back of the user. After the airflow is squeezed out of the air chamber 40a, it will flow in the gap between the back of the user and the body, and the effect of preventing the air holes 42a from being shielded by the back of the user and affecting the gas pushing of the air pump can be achieved.
