Description

Technical Field

[0001] This application relates to the technical field of vacuum cleaner housings, and more particularly to a lightweight vacuum cleaner housing. Background Technology

[0002] Vacuum cleaners mainly use an electric motor to drive the blades to rotate at high speed, creating negative air pressure inside a sealed casing to suck up dust and debris.

[0003] A search revealed Chinese Patent Publication No. CN209733845 U, which discloses a vacuum cleaner housing and a vacuum cleaner, comprising a hollow, integrated exhaust section and a motor mounting section. At least one set of exhaust components is disposed at one end of the exhaust section near the motor mounting section. These exhaust components are used to expel gas drawn into the housing by the motor. The exhaust components are located near the rear end of the housing, closer to the motor, facilitating rapid gas exhaust. The vacuum cleaner includes the aforementioned vacuum cleaner housing. This invention solves the technical problem of poor exhaust performance in existing technologies.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: the hollow and integrated exhaust section and motor fixing section; the exhaust section is equipped with at least one set of exhaust components near the motor fixing section, which can exhaust air from the inside of the vacuum cleaner, but cannot reduce the impact force on the vacuum cleaner shell during operation, resulting in a reduction in the durability of the shell. Therefore, we propose a lightweight vacuum cleaner shell. Utility Model Content

The purpose of setting the number of buffer springs, buffer sponge plates, slide rods and slide rails to several, and staggering them along the inside of the storage cavity, is to better reduce the impact force of the collection box on the housing body when the vacuum cleaner is working.

[0012] Optionally, an alarm device is provided inside the storage cavity. The alarm device includes a push plate, the side of which is fixedly connected to the side of a spring telescopic rod.

This utility model, by setting up components such as sliding grooves, spring telescopic rods, and buffer springs, and through the cooperation between the buffer springs and the buffer sponge plate components, enables the collection box to be buffered by the action of the sliding rails and sliding rods. In this way, the device can reduce the damage to the housing body caused by the direct impact of the collection box on the housing body through the buffer springs and buffer sponge plates.

[0017] 2. This utility model, by setting up components such as a push plate, a miniature hydraulic cylinder, and a hydraulic rod, utilizes the cooperative relationship between the force-bearing rod and the hydraulic rod to push the hydraulic rod outward by the force of the force-bearing rod moving into the miniature hydraulic cylinder. This allows the device to activate an alarm by touching the start button on the hydraulic rod, thus reminding people to clean the garbage in the collection box in time. Attached Figure Description

[0028] Please see Figure 3 and Figure 6 An alarm device 6 is installed inside the storage chamber 3. The alarm device 6 includes a push plate 61, the side of which is fixedly connected to the side of the spring telescopic rod 52. A miniature hydraulic cylinder 62 is fixedly connected inside the storage chamber 3. One end of the miniature hydraulic cylinder 62 is slidably connected to a force rod 63 via a piston, and the other end of the miniature hydraulic cylinder 62 is slidably connected to a hydraulic rod 64 via another piston. A start button 65 is installed inside the storage chamber 3. An alarm 66 is installed on the side of the housing body 1. The function of the alarm 66 is to sound an alarm to remind people when the collection box 53 is too full.

[0029] Please see Figure 6 A return spring 67 is fixedly connected to the circumferential surface of the force-bearing rod 63. The end of the return spring 67 away from the force-bearing rod 63 is fixedly connected to the top of the miniature hydraulic cylinder 62. The function of the return spring 67 is to allow the force-bearing rod 63 to reset when the push plate 61 stops pressing the force-bearing rod 63.

[0030] Please see Figure 5 A latch 512 is slidably connected inside the through hole 511. A first latch 513 is slidably connected inside the latch 512. A second latch 514 is slidably connected inside the latch 512. A spring 515 is fixedly connected to the back side of the first latch 513. The end of the spring 515 away from the first latch 513 is fixedly connected to the front side of the second latch 514. The purpose of the first latch 513 and the second latch 514 is to block the through hole 511 and prevent the latch 512 from falling out.

[0031] Please see Figure 5A fixing plate 59 is fixedly connected to the front side of the door body 4, and a connecting plate 510 is fixedly connected to the front side of the housing body 1. A through hole 511 is opened on the side of the connecting plate 510, and the through hole 511 penetrates the side of the fixing plate 59. The function of the fixing plate 59 and the connecting plate 510 is to close the door body 4 and the housing body 1.

[0032] Please see Figure 6 The top of the force-bearing rod 63 is located on the displacement trajectory of the push plate 61, and the top of the start button 65 is located on the displacement trajectory of the hydraulic rod 64. The purpose of the top of the force-bearing rod 63 being located on the displacement trajectory of the push plate 61 is to push the force-bearing rod 63 to move when the push plate 61 moves.

The purpose of setting the number of buffer springs 55, buffer sponge plates 56, slide rods 57 and slide rails 58 to several, and staggering them along the inside of the storage cavity 3, is to better reduce the impact force of the collection box 53 on the housing body 1 when the vacuum cleaner is working.

[0034] The implementation principle of a lightweight vacuum cleaner housing according to an embodiment of this application is as follows: First, when the housing is needed, the housing body 1 is connected to the vacuum cleaner through the suction port 2, so that the dust sucked in by the vacuum cleaner can enter the collection box 53 through the connection port 54. When the vacuum cleaner is working, the suction of the vacuum cleaner will suck the dust and garbage into the collection box 53. The collection box 53 in the storage cavity 3 will shake due to the huge suction and the entry of garbage. When the collection box 53 shakes, it will hit the buffer sponge plate 56. When the collection box 53 hits the buffer sponge plate 56, the buffer sponge plate 56 will use the slide rod 57 to slide and squeeze the buffer spring 55 in the slide rail 58, thereby reducing the damage to the housing body 1 caused by the direct impact of the collection box 53 on the housing body 1.

[0035] When there is too much dust or garbage in the collection bin 53, it will press down on the spring telescopic rod 52. When the telescopic end of the spring telescopic rod 52 moves downward, it will drive the push plate 61 to move downward. When the push plate 61 moves downward, it will push the force rod 63 into the micro hydraulic cylinder 62. When the force rod 63 moves into the micro hydraulic cylinder 62, it will press the hydraulic rod 64 to move out of the micro hydraulic cylinder 62. When the hydraulic rod 64 moves outward, it will touch the start button 65. When the hydraulic rod 64 touches the start button 65, it will activate the alarm 66, which will then sound an alarm to remind people to clean the garbage in the collection bin 53 in time.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
