[0021] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] The terms "first", "second", and the like in the description, claims, and drawings of the present application are used to distinguish different objects, rather than to describe a particular order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product, or end including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product, or end.

[0023] In this document, referring to "embodiments" means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] The present application discloses a specific embodiment of a comfortable back strap dust collector, please see Figure 1 and Figure 2 As shown in the drawings, it comprises a shell 1 and a waist support, the lower part of the shell 1 extends outwardly to a rectangularly arranged mounting portion 11, in order to be more comfortable when carrying, the outward side of the mounting portion 11 is an arc surface, the middle part of the arc surface is low and the two ends are high, which can be understood as a spherical surface, the arc surface structure is more in line with ergonomics, which can indirectly increase the contact area with the human back, making carrying more comfortable. The outward side of the mounting portion 11 is provided with a clamping hole 12 for connecting the waist support, so that the waist support can be detachably connected with the shell 1 through the clamping hole 12.

[0025] As an improvement, the waist rest 2 is arranged on the outward side of the mounting portion 11, and the waist rest 2 is fixedly installed with a clamping piece 23 on the side facing the mounting portion 11. Specifically, in combination with Figure 3The waist rest 2 comprises a fabric sheath 21, a sponge body 22 and two clamping members 23. The fabric sheath 21 is wrapped outside the sponge body 22, and it can be understood that the sponge body 22 is filled inside the fabric sheath 21, so that the inside of the waist rest 2 is provided with the sponge body 22. One side of the fabric sheath 21 facing the mounting portion 11 is provided with mounting holes 211 for mounting the clamping members 23, and the clamping members 23 comprise disc-shaped bodies 231 and columnar bodies 232 vertically fixed at the middle portions of the disc-shaped bodies 231. The outer diameter of the disc-shaped body 231 is greater than the hole diameter of the mounting hole 211, and in the assembled state, the disc-shaped body 231 is clamped between the fabric sheath 21 and the sponge body 22, and the columnar body 232 extends out of the mounting hole 211 and extends towards the clamping hole 12 of the mounting portion 11.

[0026] It should be noted that the fabric sheath 21 is a breathable cloth, and elastic cloth or other fabric can also be used to improve the carrying comfort of the waist rest. When manufacturing the waist rest, the sponge body 22 of appropriate size can be cut first, and then the planar fabric is wrapped outside the sponge body 22 by cutting and sewing to form the fabric sheath 21. Then the mounting holes 211 are opened on the fabric sheath 21. Since the cloth has a certain toughness, even if the outer diameter of the disc-shaped body 231 is greater than the hole diameter of the mounting hole 211, it only needs to stretch the mounting hole 211 into a slot when mounting the clamping member 23, so that the disc-shaped body 231 of the clamping member 23 can be inserted between the fabric sheath 21 and the sponge body 22. In order to improve the connection strength between the clamping member 23 and the fabric sheath 21, the disc-shaped body 231 of the clamping member 23 can be adhered to the inner wall of the fabric sheath 21 by an adhesive, thereby completing the manufacturing of the entire waist rest.

[0027] When installing the waist rest, the columnar body 232 of the clamping member 23 is aligned with the clamping hole 12 of the shell 1, and then the waist rest 2 is pushed towards the mounting portion 11 of the shell 1. The cooperation between the columnar body 232 of the clamping member 23 and the clamping hole 12 is an interference fit, so that in the assembled state, the clamping member 23 is inserted and fixed in the clamping hole 12. This plug-in mode can quickly disassemble and assemble the waist rest, which is convenient for replacing and maintaining the waist rest.

[0028] Please see Figure 3 The columnar body 232 is a truncated cone structure, which is more convenient for the alignment and installation between the clamping member 23 and the clamping hole 12, and improves the convenience during assembly.

[0029] In this embodiment, the side of the waist rest 2 facing the mounting portion 11 and the side of the waist rest 2 facing outward are both arc surfaces, and the arc surface structure of the waist rest 2 is the same as that of the mounting portion 11, which is also more comfortable to fit the human waist.

[0030] As another improvement, please see Figure 4 A hook 3 is fixedly installed on the outer side of the shell 1, which is used for hanging scissors, brushes and other tools, thereby improving the applicability of the dust collector.

[0031] In order to further improve the comfort of the waist support, the sponge body 22 is provided with a plurality of spaced apart air holes 221.

[0032] Compared with the prior art, the back strap dust collector of the embodiment, by setting the detachable waist support 2 on the shell 1 of the dust collector, the sponge body 22 is arranged inside the waist support 2, when the mounting part 11 of the dust collector is pressed against the waist of the human body through the waist support 2, the sponge body 22 will be deformed and play a buffering role, so that the waist support 2 is more fully attached to the waist of the human body, and the carrying is more comfortable, and the waist support 2 can form a certain space between the back of the human body and the dust collector, which is helpful for heat dissipation of the dust collector, and can avoid heat conduction from the dust collector to the back of the human body, solve the problem of uncomfortable use in the prior art, in addition, the waist support 2 is detachable, and different sizes or shapes of the waist support 2 can be replaced, so that it is suitable for various users with different needs, and has strong applicability.

[0033] Finally, it should be noted that: the back strap dust collector disclosed by the utility model embodiment is only a preferred embodiment of the utility model, and is used for explaining the technical scheme of the utility model, not for limiting it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; the technical scheme recorded in the foregoing embodiments can still be modified, or some technical features can be replaced; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the spirit and scope of the technical scheme of the utility model embodiments.
