Description

Technical Field

[0001] This invention belongs to the field of cleaning appliance technology, and particularly relates to a HEPA rotating floating sealing ring structure for a vacuum cleaner. Background Technology

[0002] Environmental hygiene is an important factor affecting the quality of life. Therefore, as people’s requirements for quality of life continue to increase, their requirements for environmental hygiene are also getting higher and higher. However, modern people’s work pressure is increasing day by day, and they urgently need to be freed from heavy cleaning work. As a result, many floor cleaning devices have emerged to improve environmental hygiene, such as vacuum cleaners, automatic mops, sweepers and floor scrubbers.

[0003] Vacuum cleaners are now a common cleaning device in both industrial and residential settings. They can be categorized by structure into upright, canister, and portable types. The working principle of a vacuum cleaner is that an electric motor drives blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris. Upright, canister, and portable vacuum cleaners each have their own advantages and disadvantages, suitable for their respective applications. However, in practice, it's often necessary to use a vacuum cleaner in different situations, and existing vacuum cleaners are unlikely to be suitable for all these scenarios simultaneously.

[0004] Currently, in many large vertical dust collectors, the dust cup seal ring often folds out at the location of the seal ring between the dust cup and the motor air inlet. Whether the dust cup is removed or put in, the seal ring is easily deformed. After long-term use, this can easily lead to seal failure, resulting in a poor sealing experience. Summary of the Invention

[0005] The purpose of this invention is to provide a HEPA rotating floating sealing ring structure for vacuum cleaners, which addresses the problem of sealing ring deformation and failure caused by removing or inserting the dust cup in large upright vacuum cleaners, thus affecting the user experience.

[0006] To achieve the above objectives, the present invention provides a HEPA rotary floating seal ring structure for a vacuum cleaner, comprising:

[0007] The HEPA support includes a top HEPA support and a bottom HEPA support. The top HEPA support is rotatably connected to the bottom HEPA support. At least one first mounting groove is provided on each side of the bottom HEPA support.

[0008] An elastic component is installed in the first mounting groove, and the top of the elastic component is connected to the Shanghai Pa bracket;

[0009] A sealing ring is provided, which is sealed to the upper and lower HEPA supports, and the sealing ring is an elastic sealing ring.

[0010] As a further description of the above technical solution:

[0011] The lower HEPA support is provided with two connecting holes, and connecting shafts are provided on both sides of the HEPA support, with the connecting shafts rotatably connected in the connecting holes.

[0012] As a further description of the above technical solution:

[0013] The Shanghai Pa bracket has a first connecting plate on each side in the middle, and the connecting shaft is connected to the first connecting plate.

[0014] As a further description of the above technical solution:

[0015] Two second connecting plates are provided on the outer side of the Shanghai Pa bracket. The sealing ring is provided with through holes through which the second connecting plates pass. The second connecting plates are located above the first mounting groove. A limiting plate is provided at the bottom of the second connecting plates. The elastic component is connected to the limiting plate.

[0016] As a further description of the above technical solution:

[0017] A top plate is provided on the second connecting plate. After the HEPA bracket is removed from the vacuum cleaner, the top of the top plate is higher than the top surface of the sealing ring.

[0018] As a further description of the above technical solution:

[0019] The vacuum cleaner includes a vacuum cleaner main unit and a dust cup, the dust cup being detachably connected to the vacuum cleaner main unit, and the HEPA bracket being arranged at an angle on the dust cup.

[0020] As a further description of the above technical solution:

[0021] The upper sides of the Shanghai Pa bracket are respectively provided with pressure plates, and the sealing ring is provided with a second mounting groove corresponding to the position of the pressure plate, and the pressure plate is inserted into the second mounting groove.

[0022] As a further description of the above technical solution:

[0023] The outer side of the sealing ring is provided with a protrusion, and the second mounting groove is formed inside the protrusion.

[0024] As a further description of the above technical solution:

[0025] The sealing ring has a first deformation groove on its inner side and a second deformation groove on its outer side. Both the first deformation groove and the second deformation groove are arranged along the circumference of the sealing ring.

[0026] As a further description of the above technical solution:

[0027] The elastic component is a spring or an elastic rubber block.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. The HEPA rotating floating sealing ring structure for a vacuum cleaner provided by this invention, through the arrangement of a HEPA bracket, a lower HEPA bracket, a sealing ring, and an elastic component, ensures that when the dust cup is inserted into the vacuum cleaner main unit, the spring will push up one end of the HEPA bracket connected to the spring under the action of the spring, thereby causing the other end of the HEPA bracket to drop a certain distance. This will then press down the sealing ring away from the spring. In this way, the dust cup will not rub against the vacuum cleaner main unit and deform when it enters the vacuum cleaner main unit. When the end of the dust cup near the spring is about to enter the vacuum cleaner main unit, the top plate will press the spring down, restoring the sealing position of the sealing ring at the end near the spring. Simultaneously, the sealing position at the other end of the sealing ring will also be restored. This simple operation solves the problem of the sealing ring flipping when removing the dust cup from a large upright vacuum cleaner, improving the user experience.

[0030] 2. In the HEPA rotating floating sealing ring structure of a vacuum cleaner provided by the present invention, the sealing ring is an elastic sealing ring. During the rotation of the HEPA bracket, it can press on the sealing ring, causing the sealing ring to deform and thus causing the sealing ring to sink to one end.

[0031] 3. In the HEPA rotating floating sealing ring structure for a vacuum cleaner provided by the present invention, the sealing ring is provided with a first deformation groove and a second deformation groove, which can facilitate the deformation of the sealing ring by the HEPA bracket and also facilitate its restoration.

[0065] The lower HEPA bracket is provided with a clearance groove corresponding to the position of the first connecting plate, which can make the width of the clearance groove greater than the width of the first connecting plate, so as to facilitate the movement of the first connecting plate.

[0113] In another implementation, the elastic component can be replaced with an electric cylinder, which can also achieve the reciprocating motion of the Shanghai Pa support.

[0114] Working Principle: The system utilizes a combination of a Shanghai Pa bracket, a lower Shanghai Pa bracket, a sealing ring, and elastic components. When the dust cup is inserted into the vacuum cleaner's main unit, the spring pushes up the end of the Shanghai Pa bracket connected to the spring, causing the other end of the Shanghai Pa bracket to descend. This, in turn, presses down on the end of the Shanghai Pa bracket away from the spring, preventing the dust cup from deforming due to friction with the vacuum cleaner's main unit. As the end of the dust cup near the spring approaches the vacuum cleaner's main unit, the top plate presses the spring down, restoring the sealing position of the sealing ring at the spring-near end. Simultaneously, the sealing position at the other end of the sealing ring also returns to normal. This simple operation solves the problem of the sealing ring flipping up when removing the dust cup from large upright vacuum cleaners, improving the user experience. The sealing ring is elastic. During the rotation of the Shanghai Pa bracket, it can be pressed against the sealing ring, causing it to deform and descend. The sealing ring has a first deformation groove and a second deformation groove, facilitating deformation by the Shanghai Pa bracket and allowing for easy restoration of its original position.

[0115] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
