Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a vacuum cleaner. Background Art

[0002] Existing vacuum cleaners are usually used for vacuuming alone without a blowing function. When users use vacuum cleaners, they can only use a hair dryer as an auxiliary when they need to blow air. The vacuum cleaner and the hair dryer are two separate products, which not only makes the user's use cost higher, but also takes up more storage space when stored separately. Utility Model Content

[0003] Based on this, it is necessary to provide a vacuum cleaner that can both blow air and vacuum, is easy to store and has a relatively low cost.

[0004] A vacuum cleaner includes a dust box and a fan device, wherein the dust box has a dust collecting cavity and an air suction port and an air outlet respectively connected to the dust collecting cavity, and the fan device has an air inlet and an air blowing port, and the fan device is detachably mounted on the dust box; when the fan device is detached from the dust box, the fan device is used to suck air and blow air through the air blowing port. When the fan device is mounted on the dust box, the air inlet is connected to the air outlet, and the fan device is used to suck air into the dust collecting cavity through the air suction port.

[0005] In one embodiment, the dust box includes a detachably connected upper cover and a lower box body, the upper cover is arranged on the lower box body, and a dust collecting chamber is formed between the upper cover and the lower box body; the upper cover has an exhaust chamber, the fan device is detachably mounted on the upper cover, and the blowing port can be connected to the exhaust chamber. It can be understood that, with such a configuration, when the vacuum cleaner performs a vacuuming operation, the air in the dust collecting chamber is sucked by the fan device and then enters the exhaust chamber from the blowing port. The exhaust chamber is used to buffer the air blown out from the blowing port.

[0006] In one embodiment, a recessed portion is formed on the upper cover, and the exhaust cavity is arranged around the recessed portion, and the fan device is installed in the recessed portion. It can be understood that, in such a configuration, the exhaust cavity located around the fan device can limit the fan device, thereby reducing the shaking of the fan device, and is conducive to increasing the extension length of the exhaust cavity, thereby increasing the volume of the exhaust cavity.

[0007] In one of the embodiments, a through hole is opened on the side wall of the exhaust cavity, and the air outlet extends into the exhaust cavity through the through hole.

[0008] In one of the embodiments, a locking structure is further included. The locking structure and the through hole are located on two opposite sides of the fan device, and the locking structure is used to cooperate with the through hole to connect the corresponding two ends of the fan device to the upper cover.

[0009] In one embodiment, the locking structure includes a card block, one of the fan device and the upper cover is provided with a card slot, one end of the card block is movably connected to the other of the fan device and the upper cover, and the other end is releasably inserted into the card slot to lock the fan device to the upper cover. It is understandable that, in this configuration, the locking structure can be quickly locked or unlocked.

[0010] In one embodiment, the number of the card slots is two, and the two card slots are opened on two opposite side walls of the fan device, and the number of the card blocks is two, and the two card blocks are respectively used to plug and cooperate with the two card slots. It can be understood that such a configuration further improves the firmness of the locking connection between the fan device and the upper cover.

[0011] In one embodiment, the locking structure includes a mounting seat and an elastic reset member, the mounting seat is fixedly connected to the upper cover, the clamping block is slidably clamped to the mounting seat, one end of the elastic reset member is connected to the mounting seat, and the other end elastically acts on the clamping block so that at least a portion of the clamping block remains protruding from the mounting seat. It can be understood that in such a configuration, the elastic reset member is used to apply an elastic force to the clamping block, so that the fan device can remain locked and connected to the upper cover.

[0012] In one embodiment, the dust box further includes an air inlet pipe, one end of which is located outside the exhaust cavity for connecting to the external environment, and the other end of which passes through the exhaust cavity and extends into the dust collecting cavity. It is understandable that, in such a configuration, the air inlet pipe passes through the exhaust cavity without being exposed, so that the exterior of the vacuum cleaner looks beautiful and neat, and the air entering the dust collecting cavity through the air inlet pipe can be isolated from the air in the exhaust cavity to avoid wind blowing during the vacuuming operation.

[0013] In one embodiment, the air inlet pipe includes an air inlet section and an air outlet section, the air inlet section is used to extend out of the exhaust cavity and form an air suction port, the air outlet section is used to extend into and connect with the dust collecting cavity, and the air inlet section and the air outlet section are arranged at an angle. The axis of the air inlet section is parallel to the axis of the through hole, and when the blowing port extends into the exhaust cavity through the through hole, the blowing port is staggered with the air inlet section and the air outlet section. It can be understood that such an arrangement facilitates the arrangement of the air inlet pipe in the exhaust cavity, and when the fan device is installed in the dust collecting box for dust collection operation, it can avoid the air inlet pipe interfering with the blowing port for blowing.

[0014] In one embodiment, the vacuum cleaner further includes a plurality of accessories, and the outer wall of the dust box is provided with a plurality of mounting positions, and the mounting positions are used to detachably mount a plurality of accessories; wherein the plurality of accessories are respectively used to be mounted to the blowing port to perform a blowing operation, or to be mounted to the suction port to perform a dust collection operation. It is understandable that, with such a configuration, when the vacuum cleaner is not in operation, the plurality of accessories are respectively mounted on the plurality of mounting positions, which is conducive to improving the integration of the vacuum cleaner, thereby facilitating storage. When the vacuum cleaner is in operation, the accessories are used to cooperate in performing a dust collection operation or a blowing operation.

[0015] Compared with the prior art, the fan device of the vacuum cleaner provided by the present application can be removed from the dust box and used separately to perform the blowing operation more flexibly, and the fan device can also be installed in the dust box and used in conjunction with the dust box as a dust suction power source to perform the dust suction operation. In this way, the vacuum cleaner has both the blowing function and the dust suction function, which can reduce the user's use cost, and the user can install the fan device in the dust box and then store it, making the vacuum cleaner compact, thereby reducing the storage space occupied.

The dust box 100 has a dust collecting chamber 110 and an air suction port 120 and an air outlet 130 respectively connected to the dust collecting chamber 110. The fan device 200 has an air inlet 210 and an air blowing port 220. The fan device 200 is detachably mounted on the dust box 100. When the fan device 200 is detached from the dust box 100, the fan device 200 is used to suck air, specifically, it can suck air through the air inlet 210. And blow air through the air blowing port 220. When the fan device 200 is installed on the dust box 100, the air inlet 210 is connected to the air outlet 130, and the fan device 200 is used to suck air into the dust collecting chamber 110 through the air suction port 120.
