Description

Technical Field

[0001] The present disclosure relates to a blower, and in particular to an anti-blocking structure for an air inlet of a blower. Background Art

[0002] Common radial low-pressure blowers usually have an air inlet arranged in the blower housing. In scenarios where the blower is required to perform a suction function, such as sucking air from an air mold, the air mold material may collapse and block the air inlet, making it impossible for the blower to continue to suck air.

[0003] WO2007022083A1 discloses an adapter attached to a blower, the end (nozzle) portion of the adapter inserted into the inflatable unit is designed to prevent the material of the inflatable unit (usually made of plastic material such as vinyl) from being sucked near the nozzle and to seal the nozzle.

[0004] CN202863798U discloses a vacuum packaging machine, whose suction head is provided with a groove and a circular air inlet. Utility Model Content

[0005] In order to provide an alternative solution for preventing air mold materials from clogging the air inlet of a blower, the present disclosure provides an anti-clogging structure for the air inlet of a blower, which includes: a mounting base for detachably connecting to the air inlet of the blower; and one or more support cylinders, which are connected in series with each other and integrally connected to the mounting base, the one or more support cylinders and the mounting base defining an air channel therein, the support cylinder including a plurality of segments arranged axially adjacent to each other, the plurality of segments including a middle segment and end segments arranged on both sides of the middle segment, a plurality of openings being provided in the end segments, wherein the plurality of segments are configured such that the diameter of the middle segment is larger than the diameter of the end segment so as to form a step between the middle segment and the end segment.

[0006] Alternatively, in some embodiments, a plurality of openings are also provided in the middle section, and the plurality of openings are in fluid communication with the air channel.

[0007] Alternatively, in some embodiments, a plurality of end segments are arranged on one side of the middle segment, wherein the diameter of the end segment adjacent to the middle segment is larger than the diameter of the end segment not adjacent to the middle segment to form steps between the end segments.

[0008] Alternatively, in some embodiments, the support cylinder is formed from two halves that are detachably connected to each other.

[0009] The anti-blocking structure for the air inlet of the blower provided by the present disclosure effectively prevents the air mold material from blocking the air inlet of the blower, especially blocking the air passage of the air inlet of the blower. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following is a further detailed description of the anti-blocking structure for the air inlet of the blower disclosed in the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following detailed description and the claims. It should be noted that the accompanying drawings are in a very simplified form and use non-precise ratios, which are only used for the purpose of conveniently and clearly assisting in explaining the embodiments of the utility model.

[0014] Reference Figure 1 The anti-clogging structure for the air inlet of the blower according to the present disclosure is described. The anti-clogging structure may include a mounting base 10 and one or more support cylinders 20.

[0015] The mounting base 10 is used to be detachably connected to the air inlet of the blower. The mounting base 10 can be connected to the air inlet of the blower via various connection devices 12, such as plug connection, threaded connection, snap connection, etc. Figure 2 As shown, the mounting base 10 may be configured in a substantially bowl shape, both ends of which are open to define an air passage 11 therein.

[0016] The one or more support cylinders 20 can be connected in series with each other and can be detachably connected to the mounting base 10 as a whole. The one or more support cylinders 20 define an air passage therein that is connected to the air passage 11, that is, the one or more support cylinders 20 and the mounting base 10 jointly define an air passage therein to allow the blower to draw air through the air passage. According to actual needs, such as the size of the air mold, one, two or more support cylinders 20 can be connected in series in sequence on the mounting base 10. These support cylinders 20 are constructed identically to each other.

[0017] The support tube 20 is roughly cylindrical in shape, and each support tube 20 can include multiple sections arranged adjacent to each other in the axial direction. These sections can be formed integrally with each other. The multiple sections include an intermediate section 21 and end sections 22, 23, 24 arranged on both sides of the intermediate section 21. Multiple openings 20g are provided in the end sections 22, 23, 24. In some embodiments, multiple openings 20g are also provided in the intermediate section 21. The openings 20g are formed in the material of the section through and are therefore communicated with the air channel fluid.

[0018] As used herein, the term "axial direction" refers to the direction of the central axis of the support cylinder.

[0019] The plurality of segments are configured such that the diameter of the middle segment 21 is larger than the diameters of the end segments 22, 23, 24, and a step 20s is formed between the middle segment 21 and the end segments 22, 23, 24. Figure 3 shown.

[0020] In some embodiments, a plurality of end segments are arranged on one side of the middle segment 21, wherein the diameter of the end segment adjacent to the middle segment 21 is larger than the diameter of the end segment not adjacent to the middle segment 21. In particular, when two or more end segments are arranged on one side of the middle segment 21, the diameters of the plurality of end segments gradually decrease in the direction away from the middle segment 21, that is, the diameter of the end segment closer to the middle segment 21 is larger. In this way, the support tube 20 is olive-shaped, thick in the middle and gradually thinning toward both ends.

[0021] For example, as attached Figure 1 As shown, one end segment 22 is arranged on one side of the middle segment 21, and two end segments 23, 24 are arranged on the other side. The diameter of the end segment 23 is larger than the diameter of the segment 24, and a step 20s is formed between the end segments 23, 24.

[0022] As used herein, "diameter" may refer to the diameter at the edge of a segment, and the diameter difference between the edges of adjacent segments forms a step 20s therebetween. The presence of the step 20s is intended to support the gas model material by the segment with a larger diameter to prevent the gas model from collapsing on the segment with a smaller diameter.

[0023] Reference Figure 3 The support cylinder 20 is formed of two halves 20a, which are detachably connected to each other. The two halves 20a substantially divide the support cylinder 20 in half in the axial direction.

[0024] The half part 20a is provided with a first column 252 and a first receptacle 251 which are plugged and connected to each other at its interconnected edges. In particular, the half part 20a is provided with a first column 252 at one edge thereof and a first receptacle 251 at the other edge.

[0025] The support cylinder 20 is plug-connected with another adjacent support cylinder 20 via the second column 261 and the second receptacle 262. Similarly, the support cylinder 20 is plug-connected with the mounting base via the second column 261 and the base receptacle 13.

[0026] The anti-blocking structure for the air inlet of the blower provided by the present disclosure effectively prevents the air mold material from blocking the air inlet of the blower, especially blocking the air passage of the air inlet of the blower.

[0027] The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] As used in this disclosure and the appended claims, the singular forms "a", "an", "said", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0029] Obviously, those skilled in the art can make various changes and modifications to the anti-blocking structure for the air inlet of the blower disclosed in the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
