Description

Vacuum cleaner with tandem suction

The present invention relates to a vacuuming device, and more particularly to a vacuum cleaner having a series suction.

There is a vacuum cleaner with a dual motor (TW publication No. 291667), which is provided with a filter sleeve and a filter at the bottom of a motor base, and a motor upper seat and a motor are arranged on the top of the motor base. An upper cover is formed, and an accommodating space is formed between the upper seat of the motor and the upper cover of the motor. The accommodating space is provided with two motors, and the motor base has a gas chamber communicating with the filter sleeve, and the motor is The suction ends are each connected to the air chamber through a vent.

Although the vacuum cleaner can be separately activated by switching a motor, or the two motors are simultaneously activated to achieve the purpose of adjusting the suction force, when the motors are simultaneously activated, the airflow inside the air chamber is disturbed, that is, two As a result of the mutual influence of the suction of the motors, the suction is diluted, and the effect of one plus one cannot be achieved.

Accordingly, it is an object of the present invention to provide a vacuum cleaner with a series suction that produces an additive suction effect by suction.

Therefore, the novel vacuum cleaner with serial suction includes a housing unit, a dust collecting unit, a first motor and a second motor. The housing unit has an air inlet, an air outlet, and a drainage channel between the air inlet and the air outlet. The dust collecting unit is mounted on the housing unit and corresponds to the air inlet. The first motor is mounted on the inside of the housing unit and disposed on the drainage channel between the air inlet and the air outlet. The second motor is mounted inside the housing unit and is serially connected to the first The motor is downstream and disposed on the drain between the first motor and the exhaust port.

The utility model has the following effects: the first motor and the second motor are connected in series with the drainage channel, and the first motor and the second motor simultaneously generate the suction force when the second motor is started, and the airflow is not disturbed. The suction effect is good.

The second sucking portion 81 communicates with the other side of the transverse space 52 through the lead-out hole 53.

As shown in FIG. 1 , FIG. 3 , FIG. 4 and FIG. 6 , when the first motor 70 and the second motor 80 are simultaneously activated, the first sucking portion 71 generates suction on the air inlet 101. Acting, and making the dust-containing airflow achieve the purpose of filtering and dust collecting when passing through the dust collecting unit 200 (as indicated by an imaginary line arrow), The filtered airflow can be introduced into the first chamber 11 from the air inlet 101 (the solid arrow in Fig. 1 shows the suction air flow path and the front path of the drain 50).

As shown in FIG. 1 , FIG. 3 and FIG. 7 , the airflow introduced into the first chamber 11 is then introduced into the drain passage 50 and passed through the introduction hole 51 , and the air flow is again sent to the first discharge portion 72 . The accommodation space 52 is located. Next, as shown in FIG. 8, the second sucking portion 81 of the second motor 80 sucks the airflow again, and is discharged to the return chamber 54 via the second discharge portion 82. At this time, as shown in FIG. 1 and FIG. 11, the valve plate 60 is subjected to the airflow discharged by the first discharge portion 72 of the first motor 70 and the second discharge portion 82 of the second motor 80 (eg, As shown in FIG. 1, the airflow path after the second discharge portion 82 of the second motor 80 is indicated by double solid arrows, and the double solid arrow is also the trailing path of the drain passage 50, and the second motor 80. The suction force generated by the second sucking portion 81 causes the valve plate 60 to be in the closed position, and the communication hole 56 is closed, that is, the transverse space 52 passes through the lead-out hole 53, the through hole 55 and the The second chamber 12 is in communication, and the airflow is restricted from being discharged from the through hole 55 toward the second chamber 12 (in FIG. 8, the flow in the second chamber 12 and the transverse space 52 is indicated by a dotted arrow). It is indicated that the air flow is finally discharged by the exhaust port 102 of the outer casing 44 (see Fig. 5).

While the first motor 70 and the second motor 80 are used for dust collection, as shown in FIGS. 1, 3, and 9, the heat dissipation air can be utilized by the action of the first fan 74 and the second fan 84.

The path, the double dashed arrow indicates the path of the first heat dissipation air duct 471 and the second heat dissipation air passage 481).

When the operation is switched and the small suction is adjusted, as shown in FIG. 2 and FIG. 12, the second motor 80 is stopped, and only the first motor 70 is operated alone, and the airflow introduced into the first chamber 11 is introduced into the drainage. The passage 50 passes through the introduction hole 51 (the solid-line arrow in FIG. 1 indicates the suction air flow path and the front path of the drainage channel 50), and the airflow is again sent to the accommodation space 52 by the first delivery portion 72. . Then, the valve plate 60 is blasted by the first discharge portion 72 of the first motor 70, and is lifted to an open position in which the communication hole 56 is opened, and the valve plate 60 is pressed against the bar. A limit is generated at the end of the 411, that is, the transverse space 52 is communicated with the second chamber 12 through the communication hole 56, and the airflow passes through the communication hole 56 (as shown in FIG. 1 The airflow path behind the communication hole 56 is indicated by double solid arrows, and the double solid arrow is also the path of the rear channel of the drainage channel 50. The conduction hole 55 is discharged toward the second chamber 12, and the airflow is finally caused by the outer casing. The exhaust port 102 of the cover 44 is exhausted (see Fig. 5).

Therefore, the novel uses the overall configuration to produce the following effects:

1. When the first motor 70 and the second motor 80 are connected in series to the drain passage 50, the first motor 70 and the second motor 80 can simultaneously generate an added suction force without causing airflow. Disturbance, good suction effect.

Second, the first motor 70 can be operated separately by operation switching, and the purpose of adjusting the suction force is achieved.

Third, the horizontal space 52 is horizontally disposed, and the first discharge portion 72 of the first motor 70 is extended in one of the lateral spaces 52, and the second motor 80 is sucked second. The portion 81 communicates with the other side of the transverse space 52 through the lead-out hole 53, and the first motor 70 and the second motor 80 are arranged side by side, thereby saving space and reducing the overall volume.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
