Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner devices, in particular to an upright vacuum cleaner capable of efficiently collecting dust. Background Art

[0002] The development of vacuum cleaners is increasingly moving towards intelligence and automation. In the prior art, a vacuum cleaner (such as an upright vacuum cleaner) can be placed on a base station to perform operations such as charging, dust collection, and cleaning the floor brush, without the operator having to perform the above actions one by one, thereby improving the convenience and efficiency of use.

[0003] For automatic dust collection, that is, the base station can collect the dust in the dust cup of the upright vacuum cleaner by itself. In the prior art, such as the application number 202320550758.7, which is a combined vacuum cleaner, it is disclosed that when the dust collector needs to be cleaned, the dust collector is inserted into the interface at the top of the air duct, and the suction motor is started. Under the action of suction, the flexible cup cover driver is deformed and squeezed downward to push the lock driver to open the flexible lock. The dust cup cover opens under the action of gravity and external force, and dust and other debris enter the dust collection bin from the air duct 4. However, in this type of vacuum cleaner, when its suction motor is started, its air inlet channel will have two, one is for the air to enter through the main unit of the vacuum cleaner body (in this process, the air to enter passes through the main unit motor of the vacuum cleaner body and enters the dust collector) and enter the base station, and the other is for the air to enter through the dust suction duct of the vacuum cleaner body to enter the base station. On the one hand, the two air inlet channels will affect the air intake efficiency and intensity, and on the other hand, the second air inlet channel cannot effectively clean the dust in the dust collector.

[0009] As a further optimization, the crimping plate and the sealing part are arranged vertically, and a limit platform is provided on the dust suction duct. The sealing part abuts against the limit platform to horizontally block the air inlet channel. The blocking effect of the limit platform can prevent the sealing part from being located in a vertical state below the rotating axis after tilting downward and rotating, thereby avoiding the subsequent inconvenience of adjusting the rotating plate to a horizontal state to block the air inlet channel.

[0010] As a further optimization, a receiving groove is provided on the inner wall of the dust suction duct for receiving the blocking portion connected to the air inlet channel in a vertical state.

[0011] As a further optimization, one end of the end of the dust cup is hinged with an end cover, and the other end is hinged with a pressure plate in a resilient manner.

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figures 1 to 4 As shown, an upright vacuum cleaner with high efficiency dust collection includes a base station 10 and an upright vacuum cleaner 20. The base station 10 is provided with a dust box 11. The dust box 11 includes an integrated motor 111, a middle cylinder 112 and an outer cylinder 113. The middle cylinder 112 is arranged in the outer cylinder 113 and is connected to the outside through a dust collecting pipe 114. The dust collecting motor 111 is arranged in the outer cylinder 113 to suck the dust in the component connected to the dust collecting pipe 114 into the middle cylinder 112. The upright vacuum cleaner 20 includes a shell 200, and a main unit component 21, a dust collecting cup 22 and a dust collecting pipe 23 arranged on the shell 200. The main unit component 21 includes a working motor, a power supply and other parts. The dust cup 22 is provided with a filter, the dust cup 22 and the dust suction pipe 23 are respectively connected to the main unit component 21 and are connected, the dust suction pipe 23 is provided with a rotating plate 241 which can rotate in its air inlet channel 230 and push and connect the air inlet channel 230 after the air enters, that is, the rotating plate 241 can open or close the air inlet channel 230, one end of the rotating plate 241 extends out of the dust suction pipe 23 to form a crimping plate 242, when the upright vacuum cleaner 20 is placed on the base station 10, the dust cup 22 is connected with the middle cylinder 112 through the dust collecting pipe 114, and the dust box 11 abuts against the crimping plate 242 so that the rotating plate 241 blocks the air inlet channel 230.

[0029] Combination Figure 8 As shown, when the upright vacuum cleaner 20 of the utility model is used for vacuuming, for example, by connecting the floor brush assembly 2a at the end of the vacuum duct 23 for cleaning the floor, the working motor in the main assembly 21 is started, and negative pressure is generated by its action. The gas enters through the air inlet channel 230 of the vacuum duct 23 through the floor brush assembly 2a, and pushes the rotating plate 241 to rotate during the upward flow in the air inlet channel to fully open the air inlet channel 230, and enters the dust cup 22 and passes through the filtering action of the filter screen located in the dust cup 22 (the dust is blocked and falls into the dust cup 22), then enters the working motor and is discharged through the first air outlet 210, completing the vacuuming action; combined with Figure 6 and Fig. 9As shown, after the upright vacuum cleaner 20 completes the vacuuming action, it is placed on the base station 10 in a vertical position, and the rotating plate 241 falls due to its own weight without external force, and because the dust box 11 abuts against the crimping plate 242, the rotating plate 241 is in a horizontal position, and maintains this horizontal position and cannot rotate, thereby blocking the air inlet channel 230 of the dust collection duct 23. After the dust cup 22 is connected to the middle cylinder 112 through the dust collecting tube 114, the dust in the dust cup 22 falls into In the dust collecting pipe 114, the dust collecting motor 111 is started, and negative pressure is generated through its action. Since the air inlet channel 230 is blocked, the gas enters through the first air outlet 210 and enters the dust collecting cup 22 through the working motor, blowing the dust on the filter screen inside the dust collecting cup 22 off and blowing the dust in the dust collecting pipe 114 into the middle cylinder 112. After passing through the dust collecting motor 111, the gas enters the gap between the middle cylinder 112 and the outer cylinder 113 and is discharged through the second air outlet 110, completing the dust collection action.

[0030] In the present invention, a rotatable rotating plate 241 is provided, and when the dust suction action is performed, the incoming air can push the rotating plate 241 to rotate so as to open the air inlet channel 230 without forming a blocked state, and smoothly enter the dust collecting cup 22 and discharge the gas after passing through the working motor. When the dust collecting action is performed, the dust collecting box 11 abuts against the crimping plate 242 so that the rotating plate 241 is in a horizontal state and maintains this state, and air cannot enter through the air inlet channel 230, so that the incoming air enters through the working motor and enters the middle cylinder 112 through the dust collecting cup 22, and then discharges the gas after passing through the dust collecting motor 111. This process can avoid the weakening of the air intake force from the working motor due to the opening of the air inlet channel 230, and all the incoming air enters from the working motor and can pass through the filter in the dust collecting cup, completing the removal of dust on the filter, and realizing efficient and comprehensive cleaning of the dust collection process.

[0031] More specifically, the rotating plate 241 includes a rotating shaft 2411 and a blocking portion 2412 connected to the rotating shaft 2411. The rotating shaft 2411 is rotatably arranged on the dust collection duct 23, and the blocking portion 2412 can rotate in the air inlet channel 230. The shape of the blocking portion 2412 matches the cross-section of the air inlet channel 230, so that a large area of ​​the air inlet channel 230 can be blocked.

[0032] The crimping plate 242 and the sealing portion 2412 are arranged vertically, that is, when the sealing portion 2412 is in a horizontal state to block the air inlet channel 230, the crimping plate 242 is in a vertical state, which can be more matched with the vertical side wall of the dust collecting box 11 (outer cylinder 113); in addition, a limit platform 231 is provided on the dust suction duct 23, and the sealing portion 2412 abuts against the limit platform 231 to horizontally block the air inlet channel 230. The limit platform 231 can limit the sealing portion 2412 from continuing to rotate downward, so as to avoid it being located below the rotating shaft 2411. Of course, the crimping plate 242 in a vertical state with the sealing portion 2412 can also achieve this function.

[0033] Furthermore, a receiving groove (not shown) is provided on the inner wall of the dust suction duct 23 for accommodating the blocking portion 2412 connected to the air inlet channel 230 in a vertical state, so as to prevent the side of the blocking portion 2412 from obstructing the air entering through the air inlet channel 230.

[0034] like Figures 5 to 7 As shown, one end of the end of the dust cup 22 is hinged with an end cover 221, and the other end is hinged with a pressure plate 222 in a resilient manner. A hook 2221 is provided on the pressure plate 222, and the hook 2221 is hung on the end cover 221 to seal the dust cup 22, and the pressure plate 222 is disengaged from the end cover 221 by pushing one end away from the hook 2221 to open the dust cup 22. If it is necessary to open the dust cup 22 separately, the dust cup 22 is taken out of the shell 200, and pressure is applied to the upper end of the pressure plate 222, and its lower end rotates around the hinge to make the hook 2221 disengage from the cover 221, and the cover 221 rotates around its hinge to open the dust cup 22.

[0035] Based on the above arrangement, if it is necessary to open the dust cup 22 on the upright vacuum cleaner 20, a top plate is required to be hinged on the shell 200 in a resilient manner, and the top plate includes a vertical plate 251 and a convex plate 252. The vertical plate 251 is hinged on the shell 200, and the convex plate 252 is arranged on the vertical plate 251 and moves to abut and push the pressure plate 222, that is, the vertical plate 251 on the shell 200 is pressed to rotate, and then the convex plate 252 at the top abuts against the pressure plate 222 and rotates the pressure plate 222 to complete the separation from the cover plate 221, thereby opening the dust cup 22; the pressing of the vertical plate 251 can be operated by the operator The vertical plate 251 can be pressed by an operator directly after the upright vacuum cleaner 20 completes the vacuuming action. The pressing of the vertical plate 251 can also be completed by the docking of the vertical plate 251 and the dust box 11 (outer cylinder 113) during the process of placing the upright vacuum cleaner 20 on the base station. For example, a raised first pressure plate 253 is provided on the side wall of the vertical plate 251, and a raised second pressure plate 115 is provided on the side wall of the outer cylinder 113. Through the docking of the first pressure plate 253 and the second pressure plate 115, the vertical plate 251 can be pushed to rotate around its hinge and drive the convex plate 252 to push the pressure plate 222.

[0036] In addition, in order to ensure the working environment of the dust collecting motor 111, a filter layer (not shown) is provided in the middle cylinder 112, which can be in the form of a filter screen to prevent dust from entering between the middle cylinder 112 and the outer cylinder 113, and can also be disassembled for cleaning or replacement.

[0037] The terminal dust suction piece of the upright vacuum cleaner 20 is a roller brush assembly 2a, which is connected to the air inlet channel 230. When the upright vacuum cleaner 20 is placed on the base station 10, it can be placed in the bottom groove 12 for positioning, fixing, or flushing; in other forms, the terminal dust suction piece can also be a pointed nozzle, etc., for facilitating cleaning of different positions.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
