Description

Technical Field

[0001] This utility model relates to the field of power tool technology, specifically a dust blowing and suction jigsaw. Background Technology

[0002] A jigsaw is a tool specifically designed for cutting curves. It is typically driven by an electric motor and equipped with a saw blade. It is widely used in woodworking, metalworking, and plastics processing to cut complex, non-linear curved shapes. The working principle of a jigsaw is to cut along the surface of the material by rapidly oscillating the saw blade.

[0003] For example, the national authorized patent announcement number CN215392889U discloses a jigsaw for cutting with a saw blade. The jigsaw includes a housing, a motor, an eccentric mechanism, an actuator, and a base. The motor, eccentric mechanism, and actuator are fixed inside the housing. The motor drives the eccentric mechanism to reciprocate, and the actuator drives the saw blade to cut. The jigsaw is characterized by having a roller frame and a drive mechanism. The roller frame is mounted on the housing, and the drive mechanism protrudes from the lower surface of the base. The movement of the saw blade causes the roller frame to rotate, which in turn drives the drive mechanism to rotate, propelling the jigsaw forward. This jigsaw can achieve self-propelled functionality, saving effort for the user.

[0004] However, the aforementioned jigsaw cannot blow away and collect the cut debris to both sides during the cutting process. As a result, the debris will quickly accumulate in the cutting area, which will obstruct the user's view. Especially when making delicate curve cuts, it is impossible to clearly see the movement trajectory of the saw blade, thus affecting the cutting accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a dust-blowing and dust-collecting jigsaw to solve the problem mentioned in the background art that during the cutting of plates, the cut debris cannot be blown away to both sides and collected in a concentrated manner, which will cause the debris to accumulate rapidly in the cutting area during the cutting process, thus obstructing the user's view and affecting the cutting accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dust-blowing and dust-collecting jigsaw includes: a jigsaw body, a blowing mechanism fixedly installed inside the base plate of the jigsaw body, the blowing mechanism being located at the rear end of the saw blade, a U-shaped mounting plate fixedly installed at one end of the outer surface of the jigsaw body, and dust-collecting mechanisms fixedly installed on both sides of the U-shaped mounting plate, the dust-collecting mechanisms being able to flip and unfold to both sides, so that the dust-collecting mechanisms can absorb and collect the wood chips blown away by the blowing mechanism.

[0008] Preferably, the purging mechanism includes a small high-pressure blower, which is fixedly installed inside the arc-shaped plate of the base plate. The nozzle of the small high-pressure blower is connected to an air pipe, and the other end of the air pipe is connected to the air knife.

[0009] Preferably, the air knife is located at the rear end of the saw blade of the jigsaw body, and the air outlet of the air knife is in a figure-eight shape with an upward tilt of °, so that it can blow the wood chips to both sides and maintain a clear cutting field of view.

[0010] Preferably, the vacuuming mechanism includes a vacuum cleaner, the outer surface of the impeller of the vacuum cleaner is fitted with a filter cover, and the lower end of the outer surface of the mesh of the filter cover is connected to a collection cylinder, which is fixedly installed at one end of the U-shaped mounting plate.

[0011] Preferably, an L-shaped plate is fixedly installed on the lower surface of the collecting cylinder, and a connecting arm is installed between the L-shaped plate and the collecting cylinder in a damped rotatable manner. A rotating ring is fixedly installed on the upper surface of the connecting arm, so that the connecting arm is rotatably connected to the collecting cylinder through the rotating ring.

[0012] Preferably, the lower surface of the connecting arm is provided with an adsorption port, which is connected to the collection cylinder through a rotating ring. The adsorption port is in a trapezoidal expansion shape, and the connecting arm can drive the adsorption port to rotate and expand within the L-shaped plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the jigsaw body, base plate, blowing mechanism, and dust collection mechanism, when cutting boards, the jigsaw body can slide against the upper surface of the board via the base plate and perform the cutting operation by pushing. Before cutting, the dust collection mechanism can be flipped open to both sides. Then, during the cutting operation, the blowing mechanism fixedly installed on the upper surface of the base plate will blow away the saw blade from the front end of the cutting process, preventing the saw blade from accumulating in the cutting area and obstructing the cutting view. Without the obstruction of saw blade, the saw blade can maintain a more stable movement path, avoiding saw blade resistance caused by sawdust accumulation, thereby improving the smoothness and accuracy of the cutting. The sawdust blown away to both sides is collected and absorbed by the dust collection mechanism that flips open to both sides, avoiding the trouble of frequently stopping to clean up sawdust during the cutting process. Users can continue cutting without interrupting their work to clean up sawdust, significantly improving work efficiency.

[0015] 2. The design incorporates a small high-pressure blower, air hose, air knife, vacuum cleaner, collection cylinder, connecting arms, and filter cover. When cutting sheet metal, the connecting arms on both sides of the U-shaped mounting plate can be rotated outwards to unfold, allowing the jigsaw body to slide against the upper surface of the sheet metal via the base plate and be pushed to perform the cutting operation. During cutting, the small high-pressure blower fixed to the upper surface of the base plate blows air into the air knife through the air hose, causing the air knife to sweep away the debris generated during cutting from the front of the saw blade, preventing debris from accumulating in the cutting area and obstructing the cutting view. The debris blown away to both sides is then sucked into the collection cylinder by the suction generated by the vacuum cleaner through the connecting arms that have flipped open to both sides. By combining the suction of the air knife and connecting arms, the debris generated during cutting can be swept away and collected immediately, eliminating the need for the operator to stop and clean the work area. This allows users to continuously perform cutting operations without frequent interruptions, thereby improving work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This embodiment provides the following technical solution:

[0025] like Figures 1-3 As shown, a dust-blowing and dust-collecting jigsaw includes: a jigsaw body 1, a blowing mechanism 3 fixedly installed in the base plate 102 of the jigsaw body 1, the blowing mechanism 3 being located at the rear end of the saw blade, a U-shaped mounting plate 101 fixedly installed at one end of the outer surface of the jigsaw body 1, and dust-collecting mechanisms 2 fixedly installed on both sides of the U-shaped mounting plate 101. The dust-collecting mechanisms 2 can be flipped and unfolded to both sides, so that the dust-collecting mechanisms 2 can absorb and collect the wood chips blown away by the blowing mechanism 3.

[0026] Through the design of the jigsaw body 1, base plate 102, blowing mechanism 3, and dust collection mechanism 2, when cutting boards, the jigsaw body 1 can slide against the upper surface of the board through the base plate 102 and perform the cutting operation by pushing. Before the cutting operation, the dust collection mechanism 2 can be flipped open to both sides. Then, during the cutting operation, the blowing mechanism 3, which is fixedly installed on the upper surface of the base plate 102, will blow away the debris generated during the cutting from the front end of the saw blade to avoid debris accumulating in the cutting area and obstructing the cutting view. Without debris obstructing the view, the saw blade can maintain a more stable movement path, avoiding saw blade resistance caused by sawdust accumulation, thereby improving the smoothness and accuracy of the cutting. The debris blown away to both sides will be concentrated and collected by the dust collection mechanism 2, which flips open to both sides, avoiding the trouble of frequently stopping to clean up debris during the cutting process. Users can continue cutting without interrupting their work to clean up sawdust, significantly improving work efficiency.

[0027] like Figures 4-6 As shown, the purging mechanism 3 includes a small high-pressure blower 301, which is fixedly installed in the arc-shaped plate of the base plate 102. The nozzle of the small high-pressure blower 301 is connected to an air pipe 302, and the other end of the air pipe 302 is connected to the air knife 303.

[0028] The air knife 303 is located at the rear end of the saw blade of the jigsaw body 1, and the air outlet of the air knife 303 is in a figure-eight shape with an upward tilt of 30°, which enables it to blow wood chips to both sides and maintain a clear cutting field of view.

[0029] The vacuuming mechanism 2 includes a vacuum cleaner 201. A filter cover 205 is fitted on the outer surface of the impeller of the vacuum cleaner 201. A collection cylinder 202 is connected and installed at the lower end of the outer surface of the mesh of the filter cover 205. The collection cylinder 202 is fixedly installed at one end of the U-shaped mounting plate 101.

[0030] An L-shaped plate 203 is fixedly installed on the lower surface of the collection cylinder 202. A connecting arm 204 is installed between the L-shaped plate 203 and the collection cylinder 202 in a damped rotatable manner. A rotating ring is fixedly installed on the upper surface of the connecting arm 204, so that the connecting arm 204 is rotatably connected to the collection cylinder 202 through the rotating ring.

[0031] The lower surface of the connecting arm 204 is provided with an adsorption port 206. The adsorption port 206 is connected to the collection cylinder 202 through a rotating ring. The adsorption port 206 is in a trapezoidal expansion shape. The connecting arm 204 can drive the adsorption port 206 to flip and unfold inside the L-shaped plate 203.

[0032] Through the design of a small high-pressure blower 301, air pipe 302, air knife 303, vacuum cleaner 201, collection cylinder 202, connecting arm 204, and filter cover 205, when cutting sheet metal, the connecting arms 204 on both sides of the U-shaped mounting plate 101 can be rotated outwards to unfold the jigsaw body 1, which can then slide against the upper surface of the sheet metal via the base plate 102 and be pushed to perform the cutting operation. During the cutting operation, the small high-pressure blower 301, fixedly mounted on the upper surface of the base plate 102, blows air into the air knife 303 through the air pipe 302, thereby enabling the air knife 303 to cut. 3. The debris generated during cutting is blown away from the front end of the saw blade to prevent it from accumulating in the cutting area and obscuring the cutting view. The debris blown away to both sides is then sucked into the collection cylinder 202 by the suction generated by the vacuum cleaner 201 through the connecting arms 204 which flips open to both sides. By combining the suction of the air knife 303 and the connecting arms 204, the debris generated during cutting can be blown away and collected in time. The operator does not need to stop to clean the work area. In this way, the user can continue to cut without frequent interruptions, thereby improving work efficiency.

[0033] Based on the above technical solution, the working steps of this solution are summarized as follows: When cutting the plate, the connecting arms 204 on both sides of the U-shaped mounting plate 101 can be rotated outwards and unfolded. Then, the jigsaw body 1 can slide against the upper surface of the plate through the base plate 102 and be pushed to perform the cutting operation. During the cutting operation, the small high-pressure blower 301 fixedly installed on the upper surface of the base plate 102 will blow air into the air knife 303 through the air pipe 302. This will allow the air knife 303 to blow away the debris generated during cutting from the front end of the saw blade. The debris blown away to both sides will be sucked into the collection cylinder 202 by the suction generated by the vacuum cleaner 201 through the connecting arms 204 that are flipped open to both sides.

[0034] In summary: This allows the saw blade to blow away the saw chips generated during cutting, preventing them from accumulating in the cutting area and obscuring the cutting view. The chips blown away to the sides are also collected by the vacuum cleaner 201, avoiding the hassle of frequently stopping to clean up the chips during the cutting process. Users can continue cutting without interrupting their work to clean up the sawdust.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
