AI Technical Summary
Existing wall sanders generate dust during operation, resulting in a harsh environment. Additionally, the heat generated by the sanding wheel can cause the motor to overheat.
An indoor wall sander with a dust collection function was designed, which includes a mounting frame, a dust collection hood, a dust filter fan and a bucket-shaped dust collection bag. Dust is collected through dust guide holes and dust guide ports, and heat is discharged by the dust filter fan to prevent the motor from overheating.
It effectively prevents dust from re-spreading, reduces pollution in the working environment, and prevents motor overheating by quickly dissipating heat, thus improving operational safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanding machine technology, specifically to an indoor wall sander with a dust collection function. Background Technology
[0002] Currently, wall sanders used in home renovations are fast, efficient, and produce smooth surfaces. However, the dust generated during operation cannot be effectively managed, resulting in a dusty working environment that seriously harms the health of workers. Furthermore, the sanding wheel generates heat during operation, which can be transferred to the motor shaft, potentially causing the motor to overheat and trigger a protective shutdown.
[0003] To address the aforementioned technical problems, this application proposes an indoor wall sander with a dust extraction function. Utility Model Content
[0004] I. Technical problems to be solved
[0005] The technical problem this invention aims to solve is that the working environment is dusty, resulting in a harsh working environment. The grinding wheel also generates heat during operation, which is transferred to the motor shaft end, easily causing the motor to overheat.
[0006] II. Technical Solution
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an indoor wall sander with a dust collection function, including a mounting frame and a dust collection hood. A partition is installed on the inner side of the middle part of the mounting frame. A grinding wheel is provided inside the front side of the mounting frame. A motor that drives the grinding wheel to rotate is installed on the rear side of the partition. The rear side of the mounting frame is connected to the front end of the dust collection hood by a thread. A dust filter fan is installed at the rear end of the dust collection hood.
[0008] The grinding wheel is provided with multiple sets of dust guide holes, the partition is provided with multiple sets of through holes communicating with the dust guide holes, a bucket-shaped dust collection bag is installed inside the dust collection hood, a suction hood is installed outside the dust collection hood, and multiple sets of dust guide ports are provided on the side wall of the dust collection hood and inside the suction hood, with the dust guide ports located in front of the bucket-shaped dust collection bag.
[0009] As an improvement, the diameter of the dust guide hole is 10-20mm, and the front sidewall is curved.
[0010] As an improvement, a protective cover is installed on the rear side of the partition and outside the motor, and a cover plate is installed on the rear side of the protective cover.
[0011] As an improvement, the rear side of the protective cover and the cover plate are located inside the bucket-shaped dust collection bag.
[0012] As an improvement, a handle is provided on the outside of the dust collection hood, and threaded connecting cylinders are respectively installed on opposite sides of the rear of the dust collection hood. Tightening bolts pass through the side walls of the handle, and the tightening bolts pass through the threads into the inside of the threaded connecting cylinders.
[0013] III. Beneficial Effects
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] 1. When the dust filter fan passes through the dust collection hood and the dust suction hood, suction is generated inside. When the sander is working, some of the dust generated enters the dust collection hood through the dust guide hole and the through hole. The dust that is scattered enters the dust suction hood and enters the dust collection hood through the dust guide port. The dust in the dust collection hood is collected into the bucket-shaped dust collection bag to prevent it from being scattered into the air again.
[0016] 2. During dust collection, the airflow speed inside the dust guide hole is relatively fast, which collects the heat generated by the grinding wheel during operation into the dust collection hood. The heat is then quickly discharged from the dust collection hood by the dust filter fan, which cools down the grinding wheel and prevents the heat from the grinding wheel from being transferred to the motor shaft end, causing the motor to overheat.
