Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The preferred embodiment of the dust bag adaptor of the blowing and sucking machine is described below with reference to the accompanying drawings.

The dust bag adapter of the blowing and sucking machine is used for connecting the dust bag with the air outlet of the blower, so that the blower can normally operate, dust or crushed particles smoothly enter the dust bag, and the environment is prevented from being polluted. Because the existing hair dryer has various specifications, the specification of the air outlet is also various. Therefore, the invention aims to provide the dust bag adapter of the blowing and sucking machine, which can be matched with air outlets of various specifications.

Referring to fig. 1 to 5, a schematic view of a dust bag adaptor of a vacuum blower and a vacuum blower connected together is shown. The dust bag adaptor of the blowing and sucking machine mainly comprises a bracket 110, an interface component 120 fixed on the bracket 110 and used for matching with the air outlet of the blower, and a pressing plate 130 for fastening the interface component 120 on the bracket 110.

Referring to fig. 1 to 5, the bracket 110 has a through hole 112 formed therein to establish a dust exhaust passage between the air outlet 210 and a dust bag (not shown). The bracket 110 includes a support portion 114 and a connection sleeve 116 connected to the support portion 114, and the through hole 112 penetrates the support portion 114 and the connection sleeve 116. The interface member 120 is a flexible element with elasticity, which is sleeved on the supporting portion 114, pressed by the pressing plate 130, and then fixed by the pin 140. The interface member 120 fits over the connection sleeve 116 to form a connection 122 beyond the end of the support 114. The connecting portion 122 is annular and has an inner passage communicating with the through hole 112. The connecting portion 122 is used to connect with the air outlet 210 of the hair dryer. Since the interface member 120 is a flexible element with elasticity, the connecting portion 122 can be expanded outward in the radial direction of the through hole 112, and the section of the inner channel of the connecting portion 122 in the radial direction of the through hole 112 is adjustable, so that the connecting portion 122 can be sleeved with air outlets of hair dryers with different specifications.

The connecting sleeve 116 of the bracket 110 is used for connecting to a dust bag. The connecting sleeve 116 can be directly connected with the dust bag or connected with the dust bag through a hose 150, depending on the type and specification of the dust bag. In order to facilitate the connection and ensure the connection effect, the outer circle or the inner circle of the connection sleeve 116 is provided with a thread structure 1162, and in this embodiment, the inner circle of the connection sleeve 116 is provided with a thread structure. Taking the dust bag connected by the hose 150 as an example, the hose 150 extends into the connecting sleeve 116, but as known to those skilled in the art, the hose 150 is flexible and has a threaded structure on its outer circle, so that the hose 150 can be screwed with the connecting sleeve 116. The hose 150 can be gradually screwed in when being installed in the connection sleeve 116, and in order to prevent over-screwing, referring to fig. 1, a limiting rib 1164 is provided on the inner circle of the connection sleeve 116 at a position adjacent to the supporting portion 114.

The interface member 120 is an expandable flexible element, which may also be said to have an elastic deformation capability. Since the connecting portion 122 is extended beyond the end of the supporting portion 114, the connecting portion 122 may be shrunk into a lump when not in use, and for convenience of use, referring to fig. 2, the end of the supporting portion 114 is further provided with a wing portion 1142 expanding one end of the connecting portion 122 outward. Thus, during installation, the connecting portion 122 can be conveniently and rapidly sleeved with the air outlet 210 of the hair dryer.

Referring to fig. 1, 2, 4 and 5, the outer circle of the connecting portion 122 is provided with a self-adhesive tape structure 124 capable of radially tightening the connecting portion 122. So-called self-adhesive tape constructions are constructions which can be glued together all around the joint or over a certain circumference and then first. This kind of structure itself is comparatively common, like the self-adhesion tightening structure of clothes cuff, the tightening belt on the umbrella etc. no longer gives unnecessary details. When the connecting portion 122 is fitted over the outlet of the hair dryer, the connecting portion 122 itself may be already tensioned and fixed to the outlet 210, and the self-adhesive tape structure 124 may be used to further secure the fixing effect. If the internal channel of the connecting portion 122 itself is not expanded, i.e. too large relative to the air outlet 210, the self-adhesive tape structure 124 can fix the connecting portion 122 to the air outlet well; however, it should be noted that even though the self-adhesive tape structure 124 is not necessary, the connecting portion 122 may be fitted over the air outlet 310 to engage with other protruding portions around the air outlet 310. In addition, the inner channel of the connecting portion 122 may be smaller than all of the air outlets, so that the connecting portion 122 is in a tensioned state when being coupled with any specification of air outlets. Alternatively, the self-adhesive tape structure 124 may be another common self-locking structure, i.e., a snap structure. Also, the locking principle of the buckle structure itself is known to the skilled person and will not be described in further detail.

Referring to fig. 1, the outer portion of the connecting portion 122 is further provided with a fastening band 126. When the connecting portion 122 is fitted over the outlet of the blower, the fastening strap 126 can be directly fastened to the body of the blower, so as to prevent the dust bag adaptor of the blower from falling off the body of the blower.

The outlet 210 of the blower of fig. 1 is substantially circular and the dust bag adaptor of the blower of the present invention can be well coupled thereto.

Referring to fig. 6-8, the dust bag adaptor of the blowing and sucking machine is shown in cooperation with the air outlet 310 of a blower of another specification. As shown in fig. 7, the elastic connection portion 122 of the dust bag adaptor of the suction blower is sleeved outside the air outlet 310 and is self-locked and fastened by the self-adhesive tape structure 124. As can be seen from fig. 7 and 8, the cross section of the outlet 310 is rectangular.

Fig. 9 to 11 are schematic views showing the dust bag adaptor of the blowing and sucking machine being matched with the air outlet 410 of a blower of another specification. As shown in fig. 9, the elastic connection portion 122 of the dust bag adaptor of the suction blower is sleeved outside the air outlet 410 and is self-locked and fastened by the self-adhesive tape structure 124. As can be seen from fig. 10 and 11, the air outlet 410 has a circular cross section, but has protrusions at partial positions on both sides thereof, which is obviously different from the air outlet 310 of fig. 4.

In summary, fig. 1 to 11 illustrate schematic diagrams of the adaptor for dust collecting bag of blower/vacuum cleaner of the present invention being coupled with various blowers with different specifications, and it can be seen that even though the shapes and specifications of the air outlets of these blowers are different, the connecting portion 122 of the adaptor for dust collecting bag of blower/vacuum cleaner can be expanded at will, so that the connecting portion 122 can be coupled with the air outlets of blowers with different specifications, thereby avoiding the trouble of replacing the adaptor, increasing the convenience of operation, and reducing the cost problem caused by the need of manufacturing various adaptors.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
