Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manual manufacturing, in particular to a handheld grinding and dust removal integrated device. Background Art
[0002] In the process of model making, in order to make the scaled model as close to the real object as possible, craftsmen will use various manufacturing methods to replicate the real object so that the produced model is consistent with the real object.
[0003] For larger models, the existing production method is usually to perform three-dimensional modeling, obtain a proportionally reduced model through additive manufacturing, and then process and color the surface of the model, thereby achieving a relatively simple method to obtain the model.
[0004] However, due to the limitations of existing additive manufacturing materials and tool choices, grinding cannot be performed inside a wet grinding machine. At the same time, due to the small size of the model and the small amount of dust generated, it is not economical to process it on large equipment.
[0005] Based on this, the utility model designs a handheld grinding and dust removal integrated equipment to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a handheld grinding and dust removal integrated device to solve the above technical problems.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a hand-held part, on which a grinding head is provided, a wind collecting hood is fixedly provided on the hand-held part near the grinding head, an extension tube is connected to the wind collecting hood, a Y-shaped tee is fixedly provided on the extension tube, and an air pump and a dust collection bag are fixedly provided on the Y-shaped tee.
[0008] By adopting the above technical solution, the wind collecting hood can achieve the purpose of accumulating the dust generated by grinding. Through the setting of the Y-shaped tee, the extension tube can inhale the air carrying dust in the wind collecting hood and collect the dust in the dust bag, so that the small handheld grinder has the function of dust removal.
[0009] Preferably, the extension tube and the air pump are respectively arranged on two ends of the Y-shaped tee that are close to each other, and the dust collecting bag is arranged on the remaining end of the Y-shaped tee.
[0010] By adopting the above technical solution, the negative pressure generated by the air pump on the Y-shaped tee causes the dust to be restrained by the air collecting hood, then sucked into the extension tube and collected in the dust collecting bag.
[0011] Preferably, a mounting block is fixedly provided on one end of the Y-shaped tee close to the dust bag, a limiting groove is provided on the mounting block, an air inlet is provided on the dust bag, an elastic ring is fixedly provided on the air inlet, and the elastic ring is placed in the limiting groove.
[0012] By adopting the above technical solution, when the collection capacity of the dust bag decreases, the dust bag can be quickly removed from the Y-shaped tee by disassembling the elastic ring and replaced.
[0013] Preferably, a yielding groove is provided on the limiting groove.
[0014] By adopting the above technical solution, when the elastic ring is difficult to remove from the limiting groove, the elastic ring can be taken out from the giving way groove by using a tool.
[0015] Preferably, the diameter of one end of the Y-shaped tee connected to the extension pipe gradually decreases as it moves away from the Y-shaped tee.
[0016] By adopting the above technical solution, while the negative pressure generated by the airflow blown by the air pump on the side of the Y-shaped tee connected to the extension pipe remains unchanged, the gradually decreasing pipe diameter increases the gas flow rate in the extension pipe, thereby improving the ability to capture dust in the air collecting hood.
[0017] To sum up, the present application has the following beneficial technical effects: when performing grinding operations, the air pump is driven to generate negative pressure at one end of the extension tube connected to the Y-shaped tee, so that the extension tube draws in the air in the wind collecting hood, thereby achieving the effect that when performing grinding operations, the dust generated by grinding is constrained by the wind collecting hood and then sucked into the extension tube until it is collected in the dust collecting bag, which has the advantage of good dust removal effect.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] The following is combined with Figure 1 —3 Provide further details of this application.
[0026] A handheld grinding and dust removal integrated device comprises a handheld part 1.
[0027] A grinding head 2 is arranged on the handheld part 1 , a wind collecting hood 3 is fixedly arranged on the handheld part 1 near the grinding head 2 , an extension tube 4 is connected to the wind collecting hood 3 , and a Y-shaped tee 5 is fixedly arranged on the extension tube 4 .
[0028] An air pump 6 and a dust bag 7 are fixedly arranged on the Y-shaped tee 5; the extension tube 4 and the air pump 6 are respectively arranged on the two ends of the Y-shaped tee 5 that are close to each other, and the dust bag 7 is arranged on the remaining end of the Y-shaped tee 5; the diameter of the end of the Y-shaped tee 5 connected to the extension tube 4 gradually decreases as it moves away from the Y-shaped tee 5.
[0029] A mounting block 8 is fixedly provided on one end of the Y-shaped tee 5 close to the dust bag 7, a limiting groove 9 is provided on the mounting block 8, and a yield groove 10 is provided on the limiting groove 9; an air inlet (not shown in the figure) is provided on the dust bag 7, an elastic ring 11 is fixedly provided on the air inlet, and the elastic ring 11 is placed in the limiting groove 9.
[0030] The implementation principle of this embodiment is as follows: before performing the grinding operation, the air pump 6 is driven to work, and the air pump 6 blows air into the Y-shaped tee 5. Due to the different connection methods and pipe diameter settings on the Y-shaped tee 5, the air pumped in by the air pump 6 moves toward the side where the dust collecting bag 7 is installed; due to the flow of air in the Y-shaped tee 5, a negative pressure is generated on the side of the Y-shaped tee 5 connected to the extension tube 4, forcing the extension tube 4 to suck in the air in the wind collecting hood 3, and after mixing with the air in the Y-shaped tee 5, the air flows into the dust collecting bag 7 together; at this time, the grinding operation is performed, and the dust generated by the grinding is constrained in the wind collecting hood 3, and then is carried into the Y-shaped tee 5 together with the air flow sucked in by the extension tube 4, and the dust is collected in the dust collecting bag 7; when the collection capacity of the dust collecting bag 7 decreases, the elastic ring 11 can be removed from the limiting groove 9 to replace the new dust collecting bag 7 for use.
[0031] When performing grinding operations, the air pump 6 is driven to generate negative pressure at one end of the Y-shaped tee 5 connected to the extension tube 4, so that the extension tube 4 sucks in the air in the wind collecting hood 3. As a result, when performing grinding operations, the dust generated by grinding is constrained by the wind collecting hood 3 and then sucked into the extension tube 4 until it is collected in the dust collecting bag 7, which has the advantage of good dust removal effect.
