Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] As shown in Figures 1 and 2, a portable industrial vacuum cleaner includes a dust collection bin 101, a dust collection bin cover 201, an air jet mechanism, and a base 102. The base 102 is located at the bottom of the dust collection bin 101 and is used to move the device. The dust collection bin cover 201 is located at the top of the dust collection bin 101. The air jet mechanism is located on the dust collection bin cover 201 and communicates with the inside of the dust collection bin 101 for cleaning the dust collection bin 101.

[0035] As shown in Figure 5, the top of the base 102 is provided with a placement groove 402 for placing the dust collection bin 101; the rear side of the base 102 is provided with a push-pull rod 104 to facilitate the movement of the device by the staff; the bottom of the base 102 is provided with multiple rollers 103 to facilitate the movement of the dust collection bin 101 with the base 102.

[0036] As shown in Figure 5-10, the dust collection bin 101 has two upward-opening chambers, both used to collect sucked-in debris. A movable cavity 107, cylindrical in shape and upward-opening, is located between the two chambers at the front. A guide post 108 is slidably installed inside the cavity. A lifting seat is located at the bottom of the movable cavity 107, and the bottom of the guide post 108 is connected to the movable end of the lifting seat. The lifting seat drives the guide post 108 to rise or fall along the axis of the movable cavity 107. Outlets 110 are provided on the sidewalls of the movable cavity 107 facing the two chambers respectively. An inlet hole 109 is provided on the outer side wall in front of the dust collection bin 101. The inlet hole 109 and two outlet holes 110 are all located on the same horizontal line, which facilitates the reversing operation when the guide post 108 rotates. A baffle plate 111 is provided on the outer side of the outlet hole 110. The top of the baffle plate 111 is connected to the bin wall 106 of the chamber, so that the baffle plate 111 can rotate around its connection point. When vacuuming is performed, the airflow enters the chamber from the outlet hole 110, causing the baffle plate 111 to flip up under the action of the airflow and expose the outlet hole 110, so that debris can enter through the outlet hole 110. When no airflow passes through the chamber, the baffle 111 naturally droops down and covers the outlet 110, preventing debris in the chamber from flowing back to the outlet 110. A dust collection pipe 105 is connected to the outer wall of the inlet 109, allowing the sucked-in debris to sequentially enter the chamber via the dust collection pipe 105, the inlet 109, and the outlet 110. The guide post 108 is provided with a first guide hole 1081, a second guide hole 1082, and a third guide hole 1083 along its axial direction. The first guide hole 1081 is Y-shaped, with two forks for connecting to... Two outlet holes 110, with one remaining opening for connecting to the inlet hole 109, so that the inlet hole 109 and the two outlet holes 110 are interconnected; the second guide hole 1082 and the third guide hole 1083 are both arc-shaped, and are used to connect the inlet hole 109 to the two outlet holes 110 respectively; when the guide hole column 108 moves up and down with the lifting seat, the first guide hole 1081, the second guide hole 1082 and the third guide hole 1083 are on the same horizontal line as the inlet hole 109 and the two outlet holes 110 respectively, thus forming three different connection methods.

[0037] As shown in Figures 3 and 4, the dust collection bin cover 201 has two exhaust holes 202, which are respectively located above the two chambers, allowing the gas entering the chambers to be discharged through the exhaust holes 202. Support cages 204 are respectively provided at the bottom edges of the two exhaust holes 202, and dust-proof nets are fitted on their outer sides to isolate dust carried by the airflow, preventing it from falling into the chambers. The top of the support cages 204 has an opening, and several ventilation holes are provided around it to facilitate gas flow. Above the exhaust holes 202, a motor housing 301 is also provided, with several ventilation holes. Inside the motor housing 301 is a motor 302, which serves as the power source for this device. Its air inlet faces the exhaust hole 202, and its air outlet faces the ventilation holes, used to draw air from the chambers of the dust collection bin 101 to the outside. A mounting bracket is also provided on one side of the exhaust hole 202, on which a dust-proof plate 205 is placed. The dust-proof plate 205 has several ventilation holes to facilitate gas flow, and filter cotton is provided on its bottom side for further adsorbing dust and debris.

[0038] Specifically, a sealing ring is provided at the connection between the top edge of the chamber of the dust collection bin 101 and the dust collection bin cover 201; a sealing ring is provided at the connection between the top edge of the exhaust hole 202 of the dust collection bin cover 201 and the bottom edge of the motor housing 301; the sealing rings are provided to enhance the tightness of the connection and prevent dust and debris from overflowing.

[0039] More specifically, the dust collection bin 101 and the dust collection bin cover 201 are preferably connected by a snap-fit; the motor housing 301 and the dust collection bin cover 201 are preferably connected by bolts; the snap-fit ​​connection and the bolt connection are common connection methods in the art and are not the main improvement points of this utility model, so they will not be described in detail here.

[0040] As shown in Figure 2-4, the jetting mechanism includes a high-pressure gas tank 401, two guide pipes 403, two control valves 404, and several nozzles 405. The top of the dust collection bin cover 201 has a placement groove 402, in which the high-pressure gas tank 401 is placed. One end of each of the two guide pipes 403 is connected to the high-pressure gas tank 401, and the other end is placed inside the two side support cages 204, allowing the gas inside the high-pressure gas tank 401 to enter the support cages 204. The guide pipe 403 of the part is arranged axially along the support cage 204. Several nozzles 405 are arranged around the side wall of the guide pipe 403 and connected to the inside of the guide pipe 403. The nozzles 405 are arranged facing the side wall of the support cage 204, so that the gas is sprayed by the nozzles 405 onto the dust screen, so that the residual dust on it is removed. Two control valves 404 are respectively arranged on the two guide pipes 403, and selectively control the flow of high pressure air to the two chambers according to the different connection states of the guide hole column 108.

[0041] The working principle of this embodiment is as follows:

[0042] This utility model discloses a portable industrial vacuum cleaner. When maximum efficiency is required, the lifting seat drives the guide hole column 108 to move, so that the first guide hole 1081 connects with the inlet hole 109 and the two outlet holes 110. Then, the motor 302 is turned on, so that the device operates and vacuums. The gas enters the chamber sequentially along the dust collection pipe 105, the inlet hole 109, the first guide hole 1081 and the outlet holes 110. Then, it is first isolated by the dust filter, which blocks the excess dust. Then, it is second isolated by the filter cotton on the dust filter plate 205. Finally, the gas passes through the motor 302 and is discharged from the vent on the motor housing 301. After the vacuuming is finished, the high-pressure gas tank 401 releases gas, and the control valves 404 on both sides are opened. The gas passes through the guide pipes 403 on both sides to the nozzle 405, so that the gas is sprayed by the nozzle 405 onto the dust filter, so that the residual dust on it is removed.

[0043] When alternating dust removal is required, the lifting seat drives the guide hole column 108 to move, so that the second guide hole 1082 and the third guide hole 1083 alternately connect with the inlet hole 109 and the two outlet holes 110. Then the motor 302 is turned on, so that the device runs and performs dust removal. When one side of the chamber is performing dust removal, the control valve 404 on the other side is opened, so that the high-pressure gas tank 401 releases gas to enter and remove dust. Repeating the above process can complete the dust removal and cleaning steps at the same time.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
