The dust receiving chamber 22 is for collecting dust obtained by the cyclone separation of the filtering device of the present invention, and the tilting of the filtering device 13 is relative to the inclination of the cup 11 having the dust receiving chamber 22, if there are a plurality of filtering devices for the vacuum cleaner and The filter device has a plurality of dust receiving chambers, and each of the storage chambers is independent of each other, so that the body forming the dust receiving chamber can be considered as the cup body of the present invention, that is, for having multiple filtering devices and for multiple filtering devices A separate dust absorbing chamber vacuum cleaner, corresponding to the explanation of the present invention, can be considered to have a plurality of cups, the inclination of the filtering device being inclined relative to the axis of the cup in which it is located. Of course, for other cases where there is only one dust receiving chamber, i.e. having a cup according to the invention, the inclination of the filtering device is an inclination relative to the axial direction of the individual cup. For the inclination of the filtering device of the present invention, from another point of view, if the bottom surface of the cleaner is parallel to the horizontal plane, the vacuum cleaner is placed on a horizontal surface, and the filtering device is inclined with respect to the horizontal plane.

As shown in FIG. 3 to FIG. 9 , when the dust gas is swirled in the cyclone chamber 133, the separated dust is extracted from the separation outlet 139 by the air flow and accumulated in the dust receiving chamber 22, and the dust receiving chamber 22 is disposed. Located outside the filtering device 13, that is, the dust receiving chamber 22 and the cyclone chamber 133 are mutually interconnected but spatially separated from each other. By spatially separating the dust receiving chamber 22 from the cyclone chamber 133, it is possible to prevent the dust from being flowed again. The winding back into the filtering device 13 effectively enhances the dust separation effect and prevents the filter 136 from being clogged.

As shown in FIG. 3, from the perspective of the dust receiving chamber 22, after the filter device 13 is tilted, one end of the filter device 13 adjacent to the dust receiving cavity 22 is formed with a low point 141 near the dust receiving cavity and a relatively low point 141 away from the dust receiving cavity 25. The high point 142, the separation outlet 139 is set at the high point 142. By arranging the filter device 13 obliquely, compared to the lateral placement of the same or similar structure in the prior art, when liquid dust is collected, the tilting arrangement can increase the dust collecting space, and the separation outlet 139 is set at a high point, raised The separation outlet 139 of the filtering device 13 prevents the liquid dust from being brought into the cyclone chamber again, causing clogging of the filter, which can prolong the service life of the filter, and can prevent the moisture in the liquid from entering the airflow generator and avoiding electrical Damage to the part.

In the embodiment of the present invention, the cyclone 132 is a first-order cyclone structure, and the dust entering the main body portion 131 can centrifugally pulverize the dust in the cyclone chamber 133 to further improve the dust removing effect. In other embodiments, the cyclone 132 may be a multi-stage cyclone structure, that is, in the flow direction of the airflow, the cyclone chamber 133 includes a plurality of stages of cyclone chambers that are sequentially connected, whereby the dust entering the main body portion 131 may pass through The multi-stage cyclone chamber is separated by multiple dusts to improve the dust removal effect.

In the embodiment of the drawing of the present invention, the first drainage section 121 is formed on the cup body 11, and the second drainage section 122 is formed on the main body portion 131. Since the second drainage sections 122 connected to the first drainage section 121 are respectively formed on the two components, the interconnection between the two can be achieved by a fixed structure or by mutual cooperation of the two components themselves. In other embodiments of the present invention, the first drainage section 121 directly connected to the outside and the second drainage section 122 connected to the first drainage section 121 may be directly formed on the cup body 11, and then passed through the second drainage section 122. It is connected to the main body portion 131. In the embodiment in which the first drainage section 121 and the second drainage section 122 are disposed on the cup body 11, the first drainage section 121 and the second drainage section 122 may be an integrally formed structure, or may be two separate structures. work cooperatively.

As shown in FIG. 4, the first drainage section 121 has a first intake axis X1, and the second drainage section 122 has a second intake axis X2, an angle α between the first intake axis X1 and the second intake axis X2. The angle β between the first axis Y1 and the longitudinal axis X0 is equal to 90°, that is, the two angles are 90°. Since the air flow is tangentially vented as it enters the filtering device 13, the direction of the separation inlet 138 also changes as the filtering device 13 is tilted, and the air flow introduced by the suction inlet 12 needs to be introduced into the slanting turn to be introduced into the separation inlet 138.

As shown in FIG. 4, the relationship between the first drainage section 121 and the filtering device 13 is that the first intake axis X1 and the first axis Y1 cross each other and are not perpendicular to each other, and the intake axis X1 and the first axis The angle between Y1 ranges from 30° to 60°. In the embodiment of the present invention, the first intake axis X1 is parallel to the longitudinal axis X0 for the sake of consistency with the standard. After adopting the same standard, the inclination angle of the filtering device 12 and the rotation angle of the second drainage section 24 can be made. The angle is designed accurately.

Regarding the inclination direction of the filtering device 13, in addition to the above-described angle relationship between the first axis Y1 and the longitudinal axis X0, under the premise that the inclination setting with the longitudinal axis X0 is satisfied, the filtering device 12 is compared with other components. The positional relationship of other components is as detailed below.

There is an acute angle between the two axes Y2 and the longitudinal axis X0. In a preferred embodiment of the invention, the angle between the longitudinal axis X0 and the first axis Y2 is between 5 and 30 degrees. The filter device 13 also extends obliquely with respect to the gas flow generator 6. Specifically, the angle between the first axis Y1 and the second axis Y2 ranges from 60° to 85°.

As shown in FIG. 4, due to the inclined arrangement of the filtering device 13, the airflow generator 6 extends the channel length of the airflow between the filtering device 13 and the airflow generator 6 if the original angle is maintained, in order to shorten the channel length, The airflow separated by the filtering device 13 can be quickly introduced into the airflow generator 6, so that the airflow generator 6 is also inclinedly disposed, and the airflow generator 6 is inclined upwardly toward the direction of the filter 136, so that the filtering device 13 can be shortened. The length of the airflow passage between the airflow generator 6.

As shown in FIG. 3 and FIG. 4, the airflow generator 6 extends obliquely upward, and it can be considered that the airflow generator 6 is inclined and extended upward from the lateral position, and the angle of the oblique upward is related to the inclination angle of the filtering device 13, specifically The inclination angle is considered by the two aspects of the shortest air passage between the filtering device 13 and the airflow generator 6 and does not affect the volume of the whole machine, and a suitable inclination angle is selected. In other embodiments of the present invention, the airflow generator 6 may not be tilted, and the airflow generator 6 may be placed laterally, because if placed vertically, the height of the entire handheld vacuum cleaner 100 may be increased, and the lateral placement may be used to avoid increasing the entire handheld. The height of the vacuum cleaner 100. As shown in FIG. 5, in the embodiment of the present invention, after the airflow generator 6 is tilted, the battery assembly 5 can be fully utilized by the space provided by the airflow generator 6 after tilting, so that the entire handheld can be further reduced by rational use of the space. The length of the vacuum cleaner 100, in turn, achieves the effect of reducing the volume of the entire machine.

The airflow generator 6 includes a rotating shaft (not shown) and a rotatable impeller (not shown) disposed on the rotating shaft. When the airflow generator 6 is in operation, the airflow generator 6 drives the impeller to rotate through the rotating shaft to generate a strong suction force and Under pressure, under the action of suction and pressure, the airflow flowing through the airflow generator 6 is discharged at a high speed, and the airflow at the air inlet end of the airflow generator 6 is continuously replenished to the airflow generator 6, causing an instantaneous vacuum inside the casing 3. Thus, the external dust-laden gas stream can be drawn into the dust cup assembly 1 through the dust suction inlet 12. When the hand-held vacuum cleaner 200 is in operation, the dust-containing airflow entering from the dust suction inlet 10 first enters the filtering device 13 for filtration, and the filtered dust and the like remain in the cup body 11, and the air filtered by the filtering device 13 is filtered again. The filter 136 filters the dust and moisture again, and the air filtered by the filter 136 is filtered to the airflow generator 6, and the air can be cooled during the flow to the airflow generator 6, thereby prolonging the flow.

The purpose is to directly collect dust from the dust collecting chamber 71 of the dust box 7 after loading the dust box 7, and after the dust box 7 is mounted on the hand-held vacuum cleaner, the dust in the hand-held vacuum cleaner can be poured into the set. In the dust chamber 71. That is, when the hand-held vacuum cleaner is in operation, the dust box 7 can be used as a dust collecting member, and when the hand-held vacuum cleaner is not in operation, the dust box 7 can also be used as a space for concentrated collection of dust. The dust box 7 has a simple structure and is flexible to use.

When the hand-held vacuum cleaner is in operation, the dust box 7 is assembled in combination with the hand-held vacuum cleaner. At this time, the handle assembly 4 can be used as a handle assembly of the combined structure.

In order to ensure the sealing property, the circumferential extent of the first sealing member 73 is greater than or equal to the circumferential range of the graying mouth of the hand-held vacuum cleaner. For example, if the graying mouth is round, the radius of the first sealing member 73 is greater than or equal to The radius of the gray port, if the graying port is not circular, the structure of the first sealing member 73 needs to correspond to the shape of the graying port, and then the size is equal to or larger than the size of the graying port, so as to ensure the entire circumference. Upward sealing. Considering that there are often other structural designs around the ash ash, the structure of the first sealing member 73 may also be different from the shape of the ashing port, but the shape of the first sealing member 73 must be able to surround the ash ash from the outside. It is ensured that the sealing effect can be covered, and the surrounding range can cover other structural designs around the graying opening, such as the locking portion of the dust cup cover.

There may be a plurality of preferred embodiments in the embodiments of the present invention, that is, the side fixing and the circumferential fixing do not necessarily need to be selected at the same time, and only one of the fixing methods may be selected.

In other embodiments of the present invention, the positions of the first latching portion 743 and the second latching portion 756 may be reversed, as long as the distance between the center of the second latching portion 756 and the mating portions of the two states is equal. Therefore, the positioning can be achieved in the two mounting states, that is, in the embodiment of the present invention, the distance between the first latching surface 7561 of the second latching portion 756 and the first mating portion 757 is equal to the second. The distance from the second latching surface 7562 of the latching portion 756 to the second mating portion 758. Since the distance from the first catching portion 743 to the mating portion is fixed, mutual fixation of the base portion 74 and the top portion 75 in both states can be achieved by ensuring that the varying distances are equal.

The dust box 7 is installed in the order in which the top portion 75 and the base portion 74 are first mounted together by the guidance of the circumferential structure, and the fixing between the two is achieved by the fastening structure 76. With this arrangement, the dust box 7 has a simple structure and is easy to install.

In the dust box 7 of the first embodiment, the main mating portion 742 can be engaged with the first mating portion 757 and the second mating portion 758, respectively. The two cooperation modes realize the two functions of the dust box 7. The following two methods are described separately. The vacuum cleaner combination is switched between an operating mode and a transport/storage mode by a different arrangement or cooperation of the dust box and the dust suction device.

As shown in FIGS. 19 to 21, the first engagement mode, that is, when the main mating portion 742 is mated with the first mating portion 757, is suitable for the operation mode. The main mating fixing edge 7421 cooperates with the first mating fixing edge 759 to achieve the circumferential fixing between the base portion 74 and the top portion 75, and the first latching portion 743 is fastened to the first latching surface 7561 on the side surface. The fixation between the base 74 and the top 75 is achieved on the side. The first cooperation mode is to increase the state of the dust collection space of the hand-held vacuum cleaner. In order to increase the circumferential sealing property, a circumferential seal ring 755 is provided between the base portion 74 and the top portion 75 in the circumferential direction where the main mating portion 742 is mated with the first mating portion 757, and is disposed at the first seal member 73. On the basis of the circumferential seal 755, the sealing effect of the hand-held vacuum cleaner and the dust box 7 is further ensured.

As shown in FIG. 22, the second cooperation mode is applicable to the transport/storage mode. In the second cooperation mode, the hand-held vacuum cleaner and the top 75 are fixed to each other on the side where the second mating portion 758 is located. The hand-held vacuum cleaner is stored upside down in the dust collecting chamber 71 of the dust box 7. That is, when the main mating portion 742 is mated with the second mating portion 758, the main mating fixing edge 7421 cooperates with the second mating fixing edge 760 to achieve the circumferential fixing between the base portion 74 and the top portion 75. The fixing between the base portion 74 and the top portion 75 is achieved by the first fastening portion 743 being buckled with the second fastening surface 7462. This second state is a storage state in which the hand-held vacuum cleaner is housed. In the second cooperation mode, the hand-held vacuum cleaner also has two placement modes. The first type is that the hand-held vacuum cleaner is fixed on the top portion 75 and is accommodated in the storage space surrounded by the base portion 74 and the top portion 75. The second type is The hand-held vacuum cleaner is not fixed to the top portion 75, but is placed in the base portion 74 and housed in the housing space surrounded by the base portion 74 and the top portion 75. In the first case, the dust cup cover of the hand-held vacuum cleaner may or may not be opened. In the second case, when the hand-held vacuum cleaner is placed, the handle of the hand-held vacuum cleaner can be brought close to the dust inlet 72, so that the handle can be held by the space provided by the dust inlet 72 to achieve the purpose of the mobile device. Two aspects of accommodating a hand-held vacuum cleaner are described in more detail in the description of the hand-held vacuum cleaner combination described below.

According to the description of the above two states, a separate dust box can be used for fixing and accommodating at the same time when the hand-held vacuum cleaner is matched, thereby preventing the hand-held vacuum cleaner from shaking in the dust box, and by setting the dust box It is detachable and versatile in structure, simple in structure and flexible in use. It can not only increase the dust storage cavity of the hand-held vacuum cleaner, but also can accommodate the hand-held vacuum cleaner, saving storage space and making the storage environment beautiful.

As shown in Fig. 16, in a preferred embodiment of the first embodiment of the dust bin 7 of the present invention, the top portion 75 defines a receiving cavity 751 for receiving a portion of the hand held vacuum cleaner. By the arrangement of the accommodating cavity 751, the hand-held vacuum cleaner can be partially accommodated, so that the combined vacuum cleaner and the dust box 7 are small in size, saving space.

As shown in FIG. 18, the first fixing structure 752 and the second fixing structure 753 may be respectively disposed at both ends of the top portion 75. When the hand-held vacuum cleaner is installed in the dust box 7, the hand-held vacuum cleaner and the dust box 7 are realized by the first fixing structure 752 and the second fixing structure 753 respectively engaging with the buckles of the first positioning buckle 20 and the second positioning buckle 21. Positioning between. In order to be able to accommodate different sizes of hand-held vacuum cleaners, the position of the first fixed structure 752 and the second fixed structure 753 can be adjusted. Of course, in other preferred embodiments of the present invention, other fixing structures may be provided to effect the fixing between the hand-held vacuum cleaner and the dust box 7, such as the fixing of the elastic band in the circumferential direction, or the design of the tensioning rope, and the like.

As shown in FIG. 17, in a preferred embodiment of the first embodiment of the dust box 7 of the present invention, the dust box 7 may be provided with an abutting portion 754. When the hand-held vacuum cleaner cooperates with the dust box 7, the abutting portion 754 can assist. Resist the locking part of the dust cup cover of the hand-held vacuum cleaner to allow the dust cup cover to open automatically. Of course, in other embodiments, the interference portion 754 may not be provided, and the dust cup cover of the hand-held vacuum cleaner may be manually opened. The abutting portion 754 is located within the first seal 73.

In a preferred embodiment of the first embodiment of the dust box 7 of the present invention, if the abutment portion 754 is provided, an adjustment abutment portion 754 position adjuster (not shown) may be provided such that the abutment portion 754 has at least two working positions. The first position suitable for the working mode and the second position suitable for the transport/storage mode, respectively, the resisting portion 754 is pressed against the control dust cup cover when in the first position.
