Description

Technical Field

[0001] This utility model relates to the field of angle grinder technology, and specifically to an angle grinder with a cleaning structure. Background Technology

[0002] An angle grinder, also known as a grinding machine or disc grinder, is an abrasive tool used for cutting and grinding fiberglass. It can also be used to cut profiles and pipes of stainless steel, alloy steel, and ordinary carbon steel, or to grind burrs, welds, etc. on workpieces. With a special grinding wheel, it can also cut building materials such as brick, stone, and asbestos corrugated board. With a disc wire brush or sanding disc, it can be used to remove rust and sand metal surfaces. With a polishing wheel, it can polish the surface of various materials. To prevent the grinding debris from flying everywhere, angle grinders are equipped with protective covers.

[0003] Current angle grinders lack a cleaning mechanism, generating a large amount of dust when grinding or cutting materials. If this dust is not cleaned and collected in time, it can easily enter the inside of the angle grinder, causing damage and affecting its use. In addition, operators may inhale the dust generated during grinding or cutting, which can harm their health. Utility Model Content

[0004] The purpose of this invention is to provide an angle grinder with a cleaning structure to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle grinder with a cleaning structure, comprising:

[0006] An angle grinder body, comprising a body, a main handle, a grinding disc, a protective cover, and a secondary handle. The body is provided with a cleaning structure. The secondary handle is installed on one side of the outer wall of the body. The main handle is installed at the rear end of the body. The grinding disc is installed at the lower end of the body. The protective cover covers the outside of the grinding disc.

[0007] The cleaning structure includes a housing, a partition, a fan, a suction head, a suction pipe, a corrugated pipe, and a suction hood. The housing is installed on the outer wall of the machine body. The partition is connected to the inside of the housing. The fan is installed inside the housing and located on one side of the partition. The suction head is connected to the air inlet of the fan. The suction pipe is connected to the housing. The corrugated pipe is connected to the end of the suction pipe away from the housing. The suction hood is connected to the end of the corrugated pipe away from the suction pipe.

[0008] Preferably, the cleaning structure further includes an air duct connected to the air outlet of the fan, the air outlet of the air duct penetrating and extending to the inner wall of the protective cover, and a number of short pipes are evenly and equidistantly connected to the outer wall of the air duct, the air outlets of the number of short pipes penetrating the inner wall of the protective cover and extending into the interior of the protective cover.

[0009] Preferably, the lower end face of the box is connected to a dust outlet, and the discharge end of the dust outlet is plugged with a stopper.

[0010] Preferably, the body is provided with a heat dissipation structure, which includes an opening slot, an outer cover, a horizontal plate and a cooling fan. The opening slot is formed on the outer wall of the body, the outer cover is placed outside the opening slot, the horizontal plate is connected to the inner wall of the outer cover, and the cooling fan is installed on the lower end face of the horizontal plate.

[0011] Preferably, the heat dissipation structure further includes a through groove formed on the upper end face of the outer cover, and a filter screen is installed on the inner surface of the through groove.

[0013] Preferably, a mounting bracket is installed on the outer wall of the body, and the mounting bracket is fitted onto the outside of the suction pipe.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By setting up a cleaning structure, the angle grinder has a cleaning function. When cutting or grinding materials, it blows away the dust adhering to the surface of the grinding disc and the inner wall of the protective cover, and at the same time absorbs and collects the large amount of dust generated. This avoids the situation where dust can easily enter the inside of the angle grinder and cause damage to the angle grinder due to not cleaning it in time, thus not affecting the use of the angle grinder. In addition, it also prevents the operator from inhaling the generated dust during grinding or cutting, which may cause damage to their health.

[0016] 2. By setting up a heat dissipation structure, the heat dissipation effect of the angle grinder can be enhanced during use. This solves the problem that the existing method of relying solely on heat dissipation slots results in poor heat dissipation, which leads to excessive internal temperature and causes internal component failure, stopping grinding or cutting operations. This ensures that the angle grinder can work continuously without affecting its use. In addition, it also avoids the situation where the operator is burned by touching the machine due to excessively high body temperature, ensuring safety during use. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1 and Figure 2 An angle grinder with a cleaning structure, as shown, includes:

[0028] The angle grinder body includes a body 1, a main handle 2, a grinding disc 3, a protective cover 4, and a secondary handle 6. The secondary handle 6 is installed on one side of the outer wall of the body 1, the main handle 2 is installed at the rear end of the body 1, the grinding disc 3 is installed at the lower end of the body 1, and the protective cover 4 covers the outside of the grinding disc 3.

[0029] This utility model provides, for example Figures 3-5The angle grinder shown has a cleaning structure 5 on its body 1. The cleaning structure 5 includes a housing 51, a partition 52, a fan 53, a suction head 54, a suction pipe 55, a corrugated pipe 56, and a suction hood 57. The housing 51 is installed on the outer wall of the body 1. The partition 52 is connected to the inside of the housing 51 and can divide the housing 51 into a dust collection chamber and a placement chamber. The sucked-in dust enters the dust collection chamber for collection, and the fan 53 is installed in the placement chamber. The partition 52 has openings... A filter screen is installed inside the tank to prevent dust from entering the fan 53. The fan 53 is installed inside the housing 51 and located on one side of the partition 52 (the fan 53 is a suction blower). The suction head 54 is connected to the air inlet of the fan 53. The suction pipe 55 is connected to the housing 51. The corrugated pipe 56 is connected to the end of the suction pipe 55 away from the housing 51. The suction hood 57 is connected to the end of the corrugated pipe 56 away from the suction pipe 55. The height of the suction hood 57 can be adjusted by the deformation of the corrugated pipe 56.

[0030] The cleaning structure 5 also includes a duct 58 connected to the air outlet of the fan 53. The air outlet of the duct 58 penetrates and extends to the inner wall of the protective cover 4. A number of short pipes 59 are evenly and equidistantly connected to the outer wall of the duct 58. The air outlets of the short pipes 59 penetrate the inner wall of the protective cover 4 and extend into the interior of the protective cover 4.

[0031] The lower end face of the housing 51 is connected to a dust outlet 511. A plug 512 is inserted into the discharge end of the dust outlet 511. After the angle grinder is used, the plug 512 is removed, and the dust collected in the housing 51 can be discharged through the dust outlet 511, thereby emptying the housing 51 for subsequent use.

[0032] A mounting bracket 8 is installed on the outer wall of the body 1. The mounting bracket 8 is fitted onto the outside of the suction pipe 55 to fix the suction pipe 55 and ensure stability during the suction operation.

[0033] Through the above technical solution:

[0034] When cutting or grinding materials, the air blown from the outlet of the blower 53 enters the air duct 58, then enters the short pipe 59, and finally blows into the protective cover 4. This blows out the dust adhering to the surface of the grinding disc 3 and the inner wall of the protective cover 4. At the same time, the dust suction hood 57 absorbs the dust generated during grinding or cutting, and draws it into the housing 51 through the corrugated pipe 56 and the suction pipe 55. This operation can clean and collect the large amount of dust generated during grinding or cutting, avoiding the situation where dust can easily enter the angle grinder and damage it due to not cleaning it in time. This does not affect the use of the angle grinder. In addition, it also prevents the operator from inhaling the dust generated during grinding or cutting, which could cause damage to their health.

[0035] This utility model provides, for example Figure 3 and Figure 6 The angle grinder shown has a cleaning structure. The body 1 is provided with a heat dissipation structure 7. The heat dissipation structure 7 includes an opening slot 71, an outer cover 72, a horizontal plate 73 and a cooling fan 74. The opening slot 71 is opened on the outer wall of the body 1. The outer cover 72 covers the outside of the opening slot 71. The horizontal plate 73 is connected to the inner wall of the outer cover 72. The width of the horizontal plate 73 is smaller than the width of the outer cover 72. The cooling fan 74 is installed on the lower end face of the horizontal plate 73.

[0036] The heat dissipation structure 7 also includes a through groove 75 opened on the upper end face of the outer cover 72. A filter screen is installed on the inner wall of the through groove 75 to prevent small external impurities from entering the outer cover 72.

[0037] The outer wall of the outer cover 72 is connected to a mounting plate 76, which is fixed to the body 1 by bolts.

[0038] Through the above technical solution:

[0039] When the angle grinder is in use, the cooling fan 74 inside the outer casing 72 operates, drawing outside air into the outer casing 72 through the through slot 71 and finally blowing it into the body 1 through the opening slot 75. This further enhances the heat dissipation effect of the body 1, solving the problem that the existing method of relying solely on the heat dissipation slot results in poor heat dissipation, causing the internal temperature of the body 1 to become too high, leading to internal component failure and stopping grinding or cutting operations. This ensures that the angle grinder can work continuously without affecting its use. In addition, it also avoids the situation where the operator touches the body 1 and gets burned due to excessively high body temperature, ensuring safety during use.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
