Description

Technical Field

[0001] The utility model relates to the technical field of workshop cleaning, in particular to an automatic waste material suction device. Background Art

[0002] The waste suction device is used to absorb the residual waste on site after processing in the workshop. The waste suction device generally includes a device box and an air collecting pipe connected to the device box. At present, the connection between the two is mostly achieved by directly putting the air collecting pipe on the connecting end of the device box and positioning it through a fixing kit. This connection method makes it difficult to clean the connecting pipe when the waste is sucked, and the subsequent disassembly of the suction hose causes wear to it, affecting its sealing performance. At the same time, the additional suction hose debris also generates additional cleaning costs. In addition, the commonly used air collecting pipes are mostly folded air pipes or curved pipes and hoses with smooth inner walls. When in use, the waste sucked into the air collecting pipe is settled and accumulated by its own gravity, resulting in collisions between particles, resulting in excessive noise, and adhesion between particles, which makes it difficult for the subsequent filter and cover to separate particles and air. Utility Model Content

[0003] The purpose of the utility model is to solve the problems that in the commonly used waste suction device and the air collecting pipe are directly connected and positioned by means of a fixed ring, waste fills the connection gap during waste suction, which makes the connection pipe difficult to clean, and the subsequent removal of the air suction hose causes wear to it and affects its sealing performance. At the same time, the additional air suction hose debris also generates additional cleaning costs. In addition, when the commonly used air collecting pipe is used, the waste sucked into the air collecting pipe settles and accumulates due to its own gravity, resulting in collisions between particles, resulting in excessive noise, and adhesion between particles, resulting in difficulty in the subsequent filter screen and cover to separate the particles and air. An automatic waste suction device is provided.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic waste suction device, including a device box, a connecting pipe extending from the front end of the device box, an outer end of the connecting pipe is sleeved with an air suction hose, the air suction hose includes a guide section and a positioning section, a positioning ring is provided at the joint between the positioning section and the connecting pipe, a spiral protrusion structure is provided along the inner wall of the guide section, a negative pressure fan is fixed on the device box through a mounting seat, a socket is provided on the front of the device box, and a switch is also provided on the top of the device box.

[0006] The connecting pipe is a metal hard connecting pipe.

[0007] As a further description of the above technical solution:

The outer sleeve is provided with matching inner threads at corresponding positions of the outer threads. The outer sleeve and the inner sleeve together constitute a clamping and positioning structure for the outer end of the connecting pipe.

[0013] As a further description of the above technical solution:

[0014] The mounting seat is fixed on the device box body through fasteners, and an arc seat is arranged on the upper end of the mounting seat. A plurality of pins extending from the bottom of the negative pressure fan are fixed on the arc seat in an inclined manner opposite to each other.

[0015] As a further description of the above technical solution:

[0016] A universal wheel is arranged at the bottom of the device box, and a pedal used for braking the universal wheel and switching the active state is arranged on the universal wheel.

[0017] In summary, due to the adoption of the above technical solution, the utility model has the following advantages compared with the prior art:

[0018] Beneficial effects:

[0019] 1. A spiral protrusion structure is arranged on the inner wall of the suction hose in the waste suction device, so that when in use, a spiral airflow is formed in the suction hose, and the waste particles are sucked into the suction hose along with the spiral airflow and form a relatively uniform distribution state. Compared with the traditional folded air pipe or curved pipe with a smooth inner wall, it can prevent the waste from settling and accumulating due to its own gravity, resulting in collision between particles, causing excessive noise, and adhesion between particles, which makes it difficult for the subsequent filter net and cover to separate the particles and air.

[0020] 2. In the connection method of the connecting pipe and the suction hose, the outer end of the connecting pipe is abutted against the connection between the outer and inner sleeves, and the two clamp and position the connecting pipe. The threaded positioning structure of the outer sleeve and the connecting pipe, then puts the positioning ring on the corresponding position of the suction hose between the annular protrusion and the external thread, to further position the suction hose to avoid loosening. This connection method prevents there from being an obvious gap between the suction hose and the connecting pipe, and avoids the waste filling the connection gap during waste absorption, which makes it difficult to clean the connecting pipe, and the subsequent disassembly of the suction hose, causing wear to it and affecting its sealing performance.
