Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a household vacuum cleaner with a foldable handle. Background Technology

[0002] A vacuum cleaner is a cleaning tool driven by an electric motor. Inside, it contains components such as a motor, a filtration system, and a dust bag. These components work together to generate the necessary suction. When the vacuum cleaner is working, the motor rotates at high speed, generating a powerful suction and vacuum effect that draws dust, hair, and other impurities from the air into the vacuum cleaner. After being filtered by the filtration system, the clean air is expelled.

[0003] In the existing technology, vacuum cleaners are an essential household item in daily life. They can quickly remove dust from the floor or carpet surface and absorb hair and other debris, effectively reducing indoor dust accumulation, improving the cleanliness of the home environment, and keeping the home space clean and hygienic. At the same time, their convenient operation can greatly reduce the workload of housework.

[0004] However, during the use of vacuum cleaners, since each vacuum cleaner comes with a fixed handle, and the handle is of a fixed length, the vacuum cleaner needs to be tilted when cleaning the room. When tilted, the handle is at the same tilt angle as the vacuum cleaner. This means that when cleaning certain areas, the user needs to bend over excessively to operate the vacuum cleaner. Therefore, we propose a household vacuum cleaner with a foldable handle. Utility Model Content

A secondary handle 13 is provided at one end of the limiting rod 111. One end of the limiting rod 111 is fixedly connected to the bottom end of the secondary handle 13. The bottom end of the secondary handle 13 is rotatably connected to the top end of the main handle 12. A spring 112 is provided on the inner arc surface of the arc plate 19. One end of the spring 112 is fixedly connected to the inner arc surface of the arc plate 19. The inner arc surface of the spring 112 away from the arc plate 19 is fixedly connected to the inner wall of the side plate 15. The inner wall of the side plate 15 is provided with a squeeze... The inner wall of the pressure rod 18 and the side plate 15 are slidably connected through the outer side of the pressure rod 18. One end of the pressure rod 18 is fixedly connected to the middle of the inner arc surface of the arc plate 19. A tapered tube 17 is provided at one end of the pressure rod 18, and the tapered tube 17 is slidably in contact with the inclined surface of the tapered tube 17. A lead screw 16 is provided on the inner wall of the tapered tube 17, and the lead screw 16 is threadedly connected to the outer side of the inner wall of the tapered tube 17. One end of the lead screw 16 is rotatably connected to one side of the top of the main handle 12. The vacuum cleaner body 11 is provided at the bottom end of the main handle 12, and the connection end between the bottom end of the main handle 12 and the vacuum cleaner body 11 is provided. The auxiliary handle 13 is fixedly connected to the inner rod 113. The top end of the auxiliary handle 13 is fixedly connected to the bottom end of the inner rod 113. An extension rod 14 is provided on the outer side of the inner rod 113. The outer side of the inner rod 113 is slidably connected to the inner wall of the extension rod 14. A sleeve 115 is provided on the inner bottom end of the extension rod 14. The inner bottom end of the extension rod 14 is fixedly connected to one end of the sleeve 115. An insertion rod 114 is provided inside the sleeve 115. The inside of the sleeve 115 is slidably connected to the outer side of the insertion rod 114. One end of the insertion rod 114 is slidably engaged with the inner wall of the inner rod 113.

[0027] When using this type of foldable handle household vacuum cleaner, firstly, the vacuum cleaner body 11 is equipped with a handle, referred to as the main handle 12 in this device. A secondary handle 13 is hinged to the top of the main handle 12. A side plate 15 is fixed to one side of the top of the main handle 12. A semi-circular groove with a radius of 180 degrees is formed on the inner wall of the side plate 15. A limiting rod 111 is designed on the inner wall of the semi-circular groove, with one end of the limiting rod 111 fixedly connected to the bottom end of the secondary handle 13. Currently, the main handle 12 and the secondary handle 13 are in a perpendicular state. When it is necessary to adjust the angle of the secondary handle 13, an arc-shaped plate 19 is installed in the side plate 15. A pressing rod 18 is designed on the inner side of the middle end of the arc-shaped plate 19. Then, by moving the secondary handle 13, the limiting rod 111 slides within the semi-circular groove. When it slides to the desired angle, the lead screw 16 is adjusted... The rotation causes the cone tube 17 to push the extrusion rod 18 with the external force of the inclined plane during its sliding. After being subjected to external force, the extrusion rod 18 will slide the arc plate 19 within the side plate 15. Multiple latches 110 are installed on the arc plate 19. The latches 110 are bracket-shaped. Therefore, when the arc plate 19 slides out from the side plate 15, the latches 110 will contact the limiting rod 111 and fix the position of the limiting rod 111, so that the auxiliary handle 13 remains stationary after adjustment. In this way, the position of the auxiliary handle 13 can be locked after any angle adjustment within the range of 180 degrees, ensuring the stability of the handle angle of the household vacuum cleaner in different usage scenarios. At the same time, when the auxiliary handle 13 rotates to 180 degrees, it will be in contact with the main handle 12, and the vacuum cleaner handle is in a straight storage state, effectively reducing the storage space occupied and making it easy to store.

[0028] An inner rod 113 is installed at the top of the secondary handle 13, and an extension rod 14 is designed on the outside of the inner rod 113. By pulling the extension rod 14 up on the inner rod 113, the overall length of the handle is increased, and the length of the handle can be flexibly adjusted to meet the grip needs of users of different heights. After the adjustment is completed, since a sleeve 115 is installed on the inner side of the bottom end of the extension rod 14, by pushing the insertion rod 114 in the sleeve 115, the insertion rod 114 enters the inner rod 113, thereby keeping the extension rod 14 in the position after the movement.

[0029] A spring 112 is designed inside the arc plate 19. When the pressing rod 18 is no longer under external pressure, the spring 112 will retract, pulling the arc plate 19 back, thereby releasing the lock 110 from fixing the limit rod 111, so that the secondary handle 13 can be adjusted in angle again.

[0030] Example 2: Please refer to Figure 1 - Figure 4The auxiliary mechanism 2 includes an inner plate 21, a guide rod 22 is provided on one side of the inner plate 21, and one side of the inner plate 21 is fixedly connected to one end of the guide rod 22. A tapered tube 17 is provided on the outside of the guide rod 22, and the outside of the guide rod 22 is slidably connected to the inner wall of the tapered tube 17. The outside of the inner plate 21 is fixedly connected to the inside of the side plate 15.

[0031] An inner plate 21 is installed on the inner side of the side plate 15. Four guide rods 22 are designed at the center of the inner plate 21. The outer sides of the four guide rods 22 are all located on the inner wall of the tapered tube 17. This allows the tapered tube 17 to be provided with a stable guiding trajectory through the guide rods 22 when it slides, preventing the tapered tube 17 from deviating or shaking during the sliding process. This ensures that the tapered tube 17 accurately pushes the extrusion rod 18 in a straight line, thereby ensuring that the arc plate 19 drives the locking buckle 110 to fix the limiting rod 111 smoothly and reliably, and improving the stability of the angle adjustment structure of the secondary handle 13.

[0032] Please see Figure 1 - Figure 6 By moving the secondary handle 13, the limiting rod 111 slides within the semi-circular groove. Once it reaches the desired angle, rotating the lead screw 16 causes the tapered tube 17 to push the pressing rod 18 using the external force of the inclined plane during its sliding motion. Under this external force, the pressing rod 18 slides the arc-shaped plate 19 within the side plate 15. Multiple latches 110, shaped like brackets, are installed on the arc-shaped plate 19. Therefore, when the arc-shaped plate 19 slides out of the side plate 15, the latches 110 contact the limiting rod 111, fixing its position. This keeps the secondary handle 13 in its adjusted position, allowing it to be locked in place at any angle within a 180-degree range. By pulling the extension rod 14 up onto the inner rod 113, the overall handle length is increased, allowing for flexible adjustment of the handle length to meet the gripping needs of users of different heights. After the adjustment is completed, since a sleeve 115 is installed on the inner side of the bottom end of the extension rod 14, the insertion rod 114 in the sleeve 115 is pushed to enter the inner rod 113, thus fixing the extension rod 14.

[0033] Four guide rods 22 are installed at the center of the inner plate 21. The outer sides of the four guide rods 22 are all located on the inner wall of the tapered tube 17. This allows the tapered tube 17 to be provided with a stable guide trajectory through the guide rods 22 when it slides, preventing the tapered tube 17 from deviating or shaking during the sliding process, and ensuring that the tapered tube 17 accurately pushes the extrusion rod 18 in a straight line.
