Description

Technical Field

[0001] This utility model specifically relates to the field of vacuum cleaner housing technology, and more specifically to an adjustable-angle vacuum cleaner housing. Background Technology

[0002] The vacuum cleaner casing is the external structure of the vacuum cleaner, usually made of materials such as plastic and metal. It serves to protect internal components, enhance aesthetics, and facilitate operation. The main casing of the vacuum cleaner is usually made of ABS plastic and modified PP plastic. Plastic has high impact resistance, is easy to process and mold, and has good corrosion resistance, heat resistance, and low density, which can reduce the overall weight of the vacuum cleaner. Some high-end or industrial vacuum cleaners use metal materials, such as aluminum alloy and stainless steel, which have higher strength and durability and can withstand greater external impacts. At the same time, metal materials can also improve the texture and heat dissipation performance of the vacuum cleaner. The main casing is connected to the collection part through a hose. The collection part is generally designed as a cone. High-speed airflow creates negative pressure on the inside of the collection part, and then the airflow sucks in the dust.

[0003] However, in practice, it has been noted that vacuum cleaners require the collection part to be kept close to the ground and moved continuously during use. Since most vacuum cleaners can only adjust the angle between the collection part and the handle vertically, for narrow spaces that are inaccessible to the human body, such as cabinets, walls, air conditioners, and corners, the collection part of the vacuum cleaner must be inserted to perform dust removal. Furthermore, because the collection part is inserted into the gaps, coupled with the obstructed view of the user and the one-way angle adjustment, it is impossible to ensure that the collection part remains in contact with the ground, which can easily lead to a decrease in cleaning effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-angle vacuum cleaner housing. Through the rotational cooperation of the hollow cover and the fan-shaped cover, the hollow cover can be adjusted left and right to change its tilt angle. Meanwhile, the rotational cooperation between the fixed shell and the rotating shell allows the hollow cover to tilt forward and backward, making it easier for users to clean confined spaces that are inaccessible to humans. This solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-angle vacuum cleaner housing includes a main housing, which is connected to a hollow rod on the side via a connecting hose.

A vacuum cover is movably connected to the outside of the swing component.

[0007] The rotating assembly includes a fixed shell and a rotating shell arranged symmetrically. An L-shaped clamping plate is fixedly connected to the side of the fixed shell, and the end of the L-shaped clamping plate away from the fixed shell is engaged with the rotating shell.

[0008] As a further technical solution of this utility model, the fixed shell is provided with an annular groove on the side near the rotating shell, and the rotating shell is integrally provided with an annular protrusion corresponding to the annular groove on the side near the fixed shell, and the annular protrusion and the annular groove are inserted and matched.

[0009] As a further technical solution of this utility model, the bottom of the fixed shell is integrally provided with a threaded tube connected to the swing assembly, and the threaded tube communicates with the inner side of the fixed shell. The top of the rotating shell is fixedly connected with an installation tube, and both ends of the rotating shell are respectively connected to the inner side of the hollow rod and the installation tube, and the installation tube is fixedly connected to the hollow rod.

[0010] As a further technical solution of this utility model, the swing component includes a fan-shaped cover that is movably connected to the inside of the dust collection cover. A connecting pipe is fixedly connected to the top of the fan-shaped cover, and a threaded pipe is threadedly connected to the top of the connecting pipe. A limiting ring is integrally provided on the outer side of the threaded pipe.

[0011] As a further technical solution of this utility model, the dust collection hood includes a hollow hood, and the hollow hood has an installation groove for placing a fan-shaped hood, and bearing holes are provided at both ends of the hollow hood.

[0012] The mounting groove is covered with a sealing cover, and the sealing cover is fixedly connected to the hollow cover. The fan-shaped cover fits into the sealing cover, and the sealing cover is also provided with a swing groove.

[0013] As a further technical solution of this utility model, both ends of the fan-shaped cover are fixedly connected to rotating shafts, and each rotating shaft is fitted with a mounting bearing with an interference fit, the outer ring of the mounting bearing being interference fitted with the inner side of the bearing hole.

[0014] As a further technical solution of this utility model, the connecting pipe above the fan-shaped cover passes through the swing groove, and the connecting pipe slides into the swing groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the rotating shafts at both ends of the fan-shaped cover are movably connected to the bearing holes in the hollow cover via mounting bearings, allowing the fan-shaped cover to rotate above the hollow cover. The sealing cover on the hollow cover seals the connection, and the connecting tube can swing inside the swing groove, allowing the dust collection cover and the hollow rod to swing left and right, increasing the adjustment angle of the dust collection cover. In this invention, the rotating shell is clamped to the side of the fixed shell by an L-shaped clamping plate, and the rotating shell can rotate on the side of the fixed shell, allowing the dust collection cover to be adjusted back and forth below the hollow rod. Furthermore, the threaded tube at the bottom of the fixed shell cooperates with the connecting tube, facilitating quick disassembly and reassembly of the connection, thus simplifying maintenance. In this invention, the side of the fixed shell has an annular groove, and the side of the rotating shell has an annular protrusion corresponding to the annular groove, with the annular protrusion inserted into the annular groove. Therefore, when the rotating shell rotates, it can drive the annular protrusion to rotate in the annular groove, ensuring that both the fixed shell and the rotating shell can rotate while also sealing the connection.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-8 This utility model provides an adjustable angle vacuum cleaner shell, including a main shell 1. The main shell 1 is connected to a hollow rod 3 arranged on the side through a connecting hose 2. A rotating component 4 is fixedly connected to the end of the hollow rod 3, and a swing component 5 is fixedly connected to the end of the rotating component 4 away from the hollow rod 3. A vacuum cover 6 is movably connected to the outside of the swing component 5.

[0029] The rotating component 4 includes a fixed shell 41 and a rotating shell 46 arranged symmetrically. An L-shaped clamping plate 45 is fixedly connected to the side of the fixed shell 41, and the end of the L-shaped clamping plate 45 away from the fixed shell 41 is engaged with the rotating shell 46.

[0030] In this example, the fixed shell 41 is provided with an annular groove 42 on the side near the rotating shell 46, and the rotating shell 46 is provided with an annular protrusion 48 corresponding to the annular groove 42 on the side near the fixed shell 41, and the annular protrusion 48 is inserted into the annular groove 42.

[0031] Furthermore, the bottom of the fixed shell 41 is integrally provided with a threaded tube 43 connected to the swing assembly 5, and the threaded tube 43 is connected to the inner side of the fixed shell 41. The upper part of the rotating shell 46 is fixedly connected with an installation tube 47, and the two ends of the rotating shell 46 are respectively connected to the hollow rod 3 and the inner side of the installation tube 47, and the installation tube 47 is fixedly connected to the hollow rod 3.

[0032] By adopting the above technical solution, the rotating shell 46 is snapped onto the side of the fixed shell 41 by the L-shaped clamping plate 45, and the rotating shell 46 can rotate on the side of the fixed shell 41, so that the dust cover 6 can be adjusted back and forth under the hollow rod 3. In addition, the threaded tube 43 provided at the bottom of the fixed shell 41 cooperates with the connecting tube 52, which facilitates quick disassembly and connection of the connection, thereby facilitating maintenance of the connection.

[0033] Furthermore, the swing assembly 5 includes a fan-shaped cover 51 that is movably connected to the inside of the dust collection cover 6. A connecting pipe 52 is fixedly connected to the upper part of the fan-shaped cover 51, and a threaded pipe 43 is threadedly connected to the upper part of the connecting pipe 52. A limiting ring 44 is integrally provided on the outer side of the threaded pipe 43.

[0034] More specifically, the dust hood 6 includes a hollow hood 61, and the hollow hood 61 has an installation groove for placing the fan-shaped hood 51, and both ends of the hollow hood 61 have bearing holes 64.

[0035] The mounting groove is covered with a sealing cover 62, and the sealing cover 62 is fixedly connected to the hollow cover 61. The fan-shaped cover 51 fits into the sealing cover 62. The sealing cover 62 is also provided with a swing groove 63.

[0036] Furthermore, both ends of the fan-shaped cover 51 are fixedly connected to rotating shafts 53, and each rotating shaft 53 is interference-fitted with a mounting bearing 54, the outer ring of the mounting bearing 54 being interference-fitted with the inner side of the bearing hole 64.

[0037] Furthermore, the connecting pipe 52 above the fan-shaped cover 51 passes through the swing groove 63, and the connecting pipe 52 slides into the swing groove 63.

[0038] By adopting the above technical solution, the rotating shafts 53 at both ends of the fan-shaped cover 51 are movably connected to the bearing holes 64 in the hollow cover 61 through the mounting bearings 54, so that the fan-shaped cover 51 can rotate above the hollow cover 61, and the sealing cover 62 on the hollow cover 61 can seal the connection, and the connecting pipe 52 can swing inside the swing groove 63, so that the dust collection cover 6 and the hollow rod 3 can swing left and right, increasing the adjustment angle of the dust collection cover 6.

[0039] Furthermore, the inner side of the fan-shaped cover 51 is connected to the inner side of the connecting pipe 52. The high-speed airflow sends the dust into the rotating assembly 4 through the fan-shaped cover 51 and the connecting pipe 52. Then, the high-speed airflow is sent into the inner side between the fixed shell 41 and the rotating shell 46 through the threaded pipe 43, and then the dust in the rotating shell 46 is sent into the hollow rod 3 through the mounting pipe 47.

[0040] Furthermore, the hollow cover 61 has an air inlet groove on its side. When the hollow cover 61 is in contact with the ground, the high-pressure airflow will create a negative pressure in the hollow cover 61. At this time, the external airflow can carry dust in through the air inlet groove.

[0041] The working principle of this utility model is as follows: During use, the fan-shaped cover 51 can rotate in the hollow cover 61 by means of the mounting bearing 54 installed on the rotating shaft 53, so that the hollow cover 61 can swing left and right below the hollow rod 3. The sealing cover 62 on the hollow cover 61 fits with the fan-shaped cover 51, so that the fan-shaped cover 51 seals the connection during the rotation of the inner side of the hollow cover 61. Moreover, the rotating shell 46 can rotate on the side of the fixed shell 41 by means of the L-shaped clamping plate 45, and the annular protrusion 48 on the side of the rotating shell 46 can rotate in the annular groove 42 on the side of the fixed shell 41, thereby sealing the connection between the fixed shell 41 and the rotating shell 46. Furthermore, the front and rear angle of the dust collection cover 6 below the hollow rod 3 can be adjusted by means of the rotating component 4, thereby increasing the flexibility of the dust collection cover 6 during use.
