Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to a barrel vacuum cleaner. Background Art

[0002] With the acceleration of the modern life rhythm, the demand for cleaning tools, especially vacuum cleaners, is increasing day by day. The barrel vacuum cleaner, as a cleaning device integrating large capacity, high-efficiency dust collection and partial water absorption functions, is widely used in cleaning companies, hotels, office buildings, families and other places. Its structure mainly consists of a dust collection host and a dust collection barrel. The dust collection host is installed on the dust collection barrel to realize the functions of dust collection and dust collection.

[0003] However, in the production, transportation and sales process of barrel vacuum cleaners, the packaging cost is a factor that cannot be ignored. The traditional packaging method often packs the dust collection host and the dust collection barrel separately, which not only increases the consumption of packaging materials, but also increases the volume and weight of the packaging box, thus increasing the transportation and storage costs. In addition, the separate packaging of multiple components also increases the assembly difficulty and time cost for users before use. In order to reduce the packaging cost and improve the transportation efficiency, the industry has begun to explore a packaging method of accommodating the dust collection host in the dust collection barrel. This design not only reduces the amount of packaging materials used, but also significantly reduces the volume and weight of the packaging box, making transportation and storage more convenient and economical. Specifically, by cleverly designing the connection structure and fixing method between the dust collection host and the dust collection barrel, the compact accommodation of the dust collection host in the dust collection barrel can be realized without damaging the product performance and user experience. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above technical problems and provide a barrel vacuum cleaner. This application aims to improve the accommodation structure of the vacuum cleaner host in the dust collection barrel.

[0005] A barrel vacuum cleaner includes a dust collection barrel, a host, a mounting ring, a support frame and a filter screen. The support frame is fixed at the air inlet at the bottom of the host. The host includes a working state and a storage state. In the working state, the host, the mounting ring and the filter screen are sequentially pressed and installed on the mounting opening of the dust collection barrel. An air inlet gap communicating with the air inlet is provided on the support frame, and the support frame abuts against the filter screen. In the storage state, the host, the mounting ring and the filter screen are sequentially disassembled. The host is placed into the dust collection barrel through the mounting opening, and the support frame abuts against the bottom surface of the dust collection barrel.

[0006] For the barrel vacuum cleaner according to the present application, the support frame is fixed at the air inlet of the main body. When in the working state, the support frame can expand the filter screen to prevent the filter screen from being adsorbed to the air inlet and affecting the air intake effect of the main body; when in the storage state, the support frame can support the main body on the bottom surface of the dust collection barrel, preventing the air inlet of the main body from directly contacting the bottom surface of the dust collection barrel. Since the filter screen has no support from the support frame, the filter screen can move towards the installation opening, thus creating space for the main body to be stored in the dust collection barrel. Since the main body of the present application can be stored in the dust collection barrel, the barrel vacuum cleaner can save the material used for the packaging box, thereby reducing the product cost. Moreover, after use, the user can conveniently store the main body in the dust collection barrel. At this time, the support frame can also prevent the air inlet from being directly contaminated by the dirt and dust remaining in the dust collection barrel. Relatively speaking, it is convenient for the user to clean the support frame, thus preventing dirt and dust from being sucked into the main body.

[0007] Further, a first fixing post is provided at the bottom of the main body, and a second fixing post is provided on the support frame. The first fixing post and the second fixing post are inserted and fixed to each other. The first fixing post and the second fixing post are inserted and fixed by screws, enabling the support frame to be conveniently replaced.

[0008] Still further, a limiting plate is provided on the side of the first fixing post, and a limiting groove is provided on the second fixing post. When the first fixing post and the second fixing post are inserted into each other, the limiting plate is inserted into the limiting groove for limiting. The limiting structure between the main body and the support frame formed by the cooperation of the limiting plate and the limiting groove can make the assembly of the main body and the support frame more convenient.

[0009] Still further, the support frame includes a plurality of support rings and connecting plates. The plurality of support rings are connected by the connecting plates, so that an air intake gap is formed between adjacent support rings.

[0010] Still further, a flat portion where the support rings are horizontally arranged and an inclined portion where the support rings are inclined are provided on the support frame, and the flat portion is provided in the middle of the inclined portion. The middle flat portion can facilitate the placement of the support frame on the bottom surface of the dust collection barrel, and the inclined portion can facilitate the expansion of the filter screen.

[0011] Still further, a support plane is provided in the middle of the bottom surface of the dust collection barrel, and a reinforcing convex ring is provided on the outer circle of the support plane. The support plane is used to abut against the support frame in the storage state. The support plane can facilitate the placement of the support frame, and the reinforcing convex ring can enhance the structural strength of the bottom surface of the dust collection barrel.

[0012] Still further, the outer circle of the filter screen is placed on the installation opening, and the installation ring includes a pressing outer circle, and the pressing outer circle is placed on the outer circle of the filter screen.

[0013] Further, a sealing protrusion is provided on the outer ring of the filter screen, and the pressing outer ring is pressed on the sealing protrusion.

[0014] Further, the mounting ring further includes an extended inner ring that extends into the mounting opening. The outer ring of the main body is placed on the extended inner ring, and the support frame extends from the inside of the mounting ring into the inside of the dust collection bucket.

The mounting ring 3 further includes an extended inner ring 32 that extends into the mounting opening 11. The outer ring of the main body 2 is placed on the extended inner ring 32, and the support frame 4 extends from the inside of the mounting ring 3 into the inside of the dust collection bucket 1, so that the main body 2 is pressed on the mounting ring 3, and under the weight of the main body 2, the sealing effect between the mounting ring 3 and the filter screen 5 can be further improved.

[0023] The support frame 4 is provided with an air inlet gap 45 connected with the air inlet 21, and the support frame 4 is against the filter 5, and the support frame can prop up the filter 5 to prevent the filter 5 from being adsorbed on the air inlet 21 and affecting the air intake effect of the host 2; in the storage state, the host 2, the mounting ring 3 and the filter 5 are disassembled in sequence, and the host 2 is placed in the dust bucket 1 through the mounting port 11, and the support frame 4 is against the bottom surface of the dust bucket 1 to prevent the air inlet 21 of the host 2 from directly contacting the bottom surface of the dust bucket 1. Since the filter 5 is not supported by the support frame 4, Figure 3 As shown, the filter 5 can be moved toward the installation opening 11 , thereby freeing up space for the host 2 to be stored in the dust bucket 1 .

[0024] Since the main unit 2 of the present application can be stored in the dust bucket 1, the barrel-type vacuum cleaner can save the material of the packaging box, thereby saving the cost of the product, and the user can also conveniently store the main unit 2 in the dust bucket 1 after use. At this time, the support frame 4 can also prevent the air inlet 21 from being directly contaminated by the dirt and dust retained in the dust bucket 1. The user can conveniently clean the support frame 4 relative to the air inlet 21, thereby preventing dirt and dust from being sucked into the main unit 2.

[0025] like Figure 3 As shown, the extended inner ring 32 of the mounting ring 3 is in a multi-step shape, and the outer ring of the host 2 matches the shape of the extended inner ring 32, so that a certain sealing effect can be produced when the outer ring of the host 2 is pressed on the extended inner ring 32.
