Description

Technical Field

[0001] This utility model relates to the field of surface cleaning technology, specifically to a vacuum cleaner with integrated air intake and exhaust. Background Technology

[0002] Vacuum cleaners, as an essential cleaning tool in modern households, have become ubiquitous. Current vacuum cleaners typically have four stages of filtration. The first stage is cyclone separation filtration during the dustbin's entry into the dust cup; the second stage filters large particles of dirt through a metal mesh within the dust cup; the third stage is the intake filtration (pre-filter), which filters fine particles carried in the air through a pre-filter cotton, preventing them from entering the vacuum motor; the fourth stage is the exhaust filtration (post-filter), which usually uses HEPA filters to trap tiny particles in the air, preventing them from being released into the environment.

[0003] Existing vacuum cleaners with dust cup axis perpendicular to motor axis have separate front and rear filters, meaning the third and fourth stage filters are separate. The disassembly and assembly process is cumbersome, and the air intake filter requires the dust cup to be disassembled for maintenance, which increases the chance of missing filters and reduces the lifespan of the vacuum cleaner.

[0004] Therefore, there is an urgent need to design a vacuum cleaner that integrates air intake and exhaust filtration, thereby improving the ease of assembly and disassembly. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vacuum cleaner with integrated air intake and exhaust. The front and rear filters located upstream and downstream of the vacuum motor are integrated into a single front and rear filter assembly. The front and rear filters can also be disassembled and installed relatively independently, which reduces the difficulty of disassembly and assembly for equipment maintenance, improves the convenience of equipment maintenance and the user experience.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0035] like Figures 1-3 , Figure 6 As shown, a vacuum cleaner with integrated air intake and exhaust includes a main housing 1, a filter housing 2, a dust cup 3, front and rear filter components, a handle 8, a wall mount 9, and a battery pack 10. A vacuum motor 101 is installed inside the main housing 1. The front end of the main housing 1 is fixedly connected to the filter housing 2. The front and rear filter components are detachably installed inside the filter housing 2. The filter housing 2 is located at the top of the dust cup 3. The upper end of the handle 8 is fixedly connected to the bottom of the main housing 1, and the lower end is connected to the side of the dust cup 3. The battery pack 10 is located between the handle 8 and the dust cup 3, and the wall mount 9 is fixedly installed at the bottom of the handle 8.

[0036] As described above, the upper part of the dust cup 3 is provided with an air inlet pipe 4, and a retractable brush is installed at the air inlet pipe 4; the battery pack 10 is used to power the vacuum motor 101. After the vacuum motor 101 is started, it generates negative pressure, thereby sucking external dirt into the dust cup 3 along the air inlet pipe 4. Under the cyclone separation and the filtration of the filter screen inside the dust cup 3, solid dirt is left inside the dust cup 3, while gas passes through the front filter part of the front and rear filter assembly into the vacuum motor 101, and after being discharged by the vacuum motor 101, it passes through the rear filter part of the front and rear filter assembly and is discharged into the external environment.

[0037] Among them, the wall mount 9 is an existing technology that works in conjunction with a hook fixed to the wall. That is, the bottom of the wall mount 9 has a hanging groove. Through the cooperation between the hanging groove and the hook, the vacuum cleaner can be hung on the wall for easy storage and use.

[0038] Compared to the existing split design, the integrated front and rear filters proposed in this utility model can be removed from the main body of the equipment without removing the dust cup 3. At the same time, the front filter can also be removed separately from the rear filter, which makes it easier to clean and maintain, optimizes the user experience, reduces the possibility of filter leakage, and extends the service life of the equipment. Example 1

[0039] like Figure 2 , Figure 3 and Figure 6As shown, the front and rear filter assembly includes a front filter medium 6, a rear filter medium 7, and a filter bracket 5. The front filter medium 6 is embedded in the inner front part of the filter bracket 5, and the rear filter medium 7 is sleeved on the outer rear part of the filter bracket 5. Ventilation holes are provided on the circumferential surface of the filter bracket 5 so that air can pass smoothly through the front filter medium 6 and the rear filter medium 7 to achieve filtration. An exhaust hole communicating with the rear filter medium 7 is provided on the circumferential surface of the filter housing 2.

[0040] A branch pipe 203 is fixedly installed inside the filter housing 2. The rear part of the filter bracket 5 is sleeved on the outside of the branch pipe 203, and an exhaust channel is formed between the branch pipe 203 and the filter bracket 5. The exhaust channel is used to connect the exhaust end of the vacuum motor 101 and the rear filter medium 7. The branch pipe 203 is used to connect the air inlet end of the vacuum motor 101 and the front filter medium.

[0041] Specifically, the branch pipe 203 and the rear end of the filter housing 2 are integrally connected, and a through hole is provided at the connection to ensure that the exhaust channel is connected to the exhaust end of the vacuum motor 101. The gas that has been initially filtered by the dust cup 3 first passes radially through the front filter medium 6, then enters the vacuum motor 101 axially along the branch pipe 203, is discharged by the vacuum motor 101, and then enters the exhaust channel. After passing radially through the rear filter medium 7 and the exhaust hole of the filter housing 2, it is discharged into the external environment.

[0042] The front and rear filter components here adopt an integrated air inlet and outlet design, including a front filter section and a rear filter section, which are located upstream and downstream of the vacuum motor 101, respectively. The gas entering the vacuum motor 101 is filtered by the front filter medium 6 (using filter cotton) to prevent solid particles from entering the motor and causing damage. The gas discharged from the vacuum motor 101 is filtered by the rear filter medium 7 (using HEPA) to prevent the discharged gas from carrying harmful substances and to ensure air quality.

[0043] During subsequent cleaning and maintenance, the front and rear filter components can be removed separately from the cleaning equipment as a whole, without the need to remove components such as the dust cup 3, thus improving the efficiency of maintenance and the user experience.

[0044] Furthermore, the front end of the filter support 5 is located outside the filter housing 2, and the front end of the front filter medium 6 is located outside the filter support 5. This structural design allows the filter support 5 to be easily removed from inside the filter housing 2, and also allows the front filter medium 6 to be easily removed from the filter support 5.

[0045] Since the pre-filter medium 6 adsorbs more dirt particles than the post-filter medium 7, it requires more frequent maintenance. By placing the front end of the pre-filter medium 6 on the outside of the filter bracket 5, it can be removed separately without removing the filter bracket 5, which greatly improves the ease of disassembly and assembly for pre-filter maintenance.

[0046] In addition, for ease of assembly, the front filter medium 6 and the rear filter medium 7 are coaxially arranged with the filter bracket 5, the filter bracket 5 is coaxially arranged with the branch pipe 203, the branch pipe 203 is coaxially arranged with the vacuum motor 101, and the branch pipe 203 is also coaxial with the filter housing 2. Example 2

[0047] like Figures 1-6 As shown, based on Embodiment 1, this utility model also proposes a detachable connection structure between the filter support 5 and the front filter medium 6 and the filter housing 2, that is, the filter support 5 and the front end of the filter housing 2 are detachably connected by a rotating buckle, and the front filter medium 6 and the front end of the filter support 5 are detachably connected by an elastic buckle.

[0048] Regarding the detachable connection structure between the filter bracket 5 and the filter housing 2, a swivel part 501 is provided at the front end of the filter bracket 5. The lower end of the swivel part 501 is fixedly connected to the filter bracket 5, and the other end is first folded upward and then backward to form a slot. A boss 201 is provided at the front end of the filter housing 2. The boss 201 can be inserted into the slot, and a first buckle 202 is provided on the outer side of the boss 201. A rotating slot corresponding to the first buckle 202 is opened on the inner side of the slot.

[0049] Specifically, the rotating slot adopts an L-shaped structure, including a vertical part and a horizontal part that are perpendicularly connected to each other, with the vertical part parallel to the axis of the filter bracket 5. When the filter bracket 5 is inserted into the filter housing 2, the boss 201 is inserted into the slot, and the first buckle 202 is inserted into the vertical part of the rotating slot. Then, the filter bracket 5 is rotated so that the first buckle 202 is inserted into the horizontal part, thereby completing the fixed connection between the filter bracket 5 and the filter housing 2. For removal, simply rotate the filter bracket 5 in the opposite direction and then pull it out axially.

[0050] To improve the reliability of the rotation of the filter bracket 5, anti-slip texture is provided on the outer circumferential surface of the buckle part 501. The anti-slip texture increases the contact friction, which can reduce the difficulty of rotating the filter bracket 5.

[0051] Regarding the detachable connection structure between the filter support 5 and the front filter medium 6, a support cylinder is inserted inside the filter medium 6, and ventilation holes for gas to pass through are also opened on the circumferential surface of the support cylinder. At the same time, an end cap 601 is fixedly connected to the front end of the support cylinder, and a retaining ring 602 is provided on the rear side of the end cap 601. A second buckle 502 for engaging with the retaining ring 602 is fixedly installed on the inner side of the filter support 5.

[0052] The second buckle 502 is an elastic buckle, which is fixedly connected to the filter bracket 5 at its rear side. There are gaps between the left and right front sides and the filter bracket 5, so that the second buckle 502 can generate elastic deformation in the radial direction when it is subjected to axial compression. The front end of the second buckle 502 is provided with an inwardly protruding buckle part.

[0053] Specifically, the outer diameter of the end cap 601 is larger than the outer diameter of the support cylinder, and the outer diameter of the retaining ring 602 is the same as the inner diameter of the front part of the filter bracket 5. When the current filter medium 6 is embedded in the inner side of the front part of the filter bracket 5, the retaining part of the second buckle 502 is subjected to axial compression from the retaining ring 602, thus undergoing elastic deformation radially outward until the retaining ring 602 passes over the retaining part. The second buckle 502 then resets, blocking the retaining ring 602 through the retaining part, thereby completing the fixed connection between the filter bracket 5 and the front filter medium 6. During disassembly, simply pull outward axially to allow the retaining ring 602 to pass over the second buckle 502 again to complete the disengagement.

[0054] To facilitate the pulling of the pre-filter medium 6, a groove is provided at the front end of the end cap 601, and a pull handle 603 is fixedly installed in the groove. The pull handle 603 is plate-shaped. By squeezing the pull handle 603 with your fingers, the pre-filter medium 6 can be pulled out of the filter support 5 more easily.

[0055] In addition to snap-fit ​​connections, the filter bracket 5 can also be detachably connected to the front filter medium 6 and the filter housing 2 via threaded connections, as long as the front filter medium 6 can be detached independently from the filter bracket 5 and the filter bracket 5 can be detached independently from the filter housing 2.

[0056] In summary, this utility model proposes a vacuum cleaner with integrated air intake and exhaust, in which the front and rear filter components are designed as a single unit and can be disassembled separately from the cleaning device. At the same time, the front filter part of the front and rear filter components can also be disassembled separately from the rear filter distribution. Compared with the existing split design, this structure is more convenient and quick to assemble and disassemble, which can improve maintenance efficiency and ensure that users have a better user experience.
