Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a vacuum cleaner with a speed adjustment mechanism. Background Technology

[0002] Currently, some handheld vacuum cleaners on the market are equipped with power adjustment functions, allowing users to select the appropriate power level according to the degree of dirtiness for cleaning operations to achieve better cleaning results. For example, CN211324698U discloses a handheld vacuum cleaner with a speed control switch located on the handle, while the main switch is located on the top of the machine. Due to the distance of the main switch, although users can adjust the power while holding the handle with one hand, it is difficult to control the main switch at the same time. In other words, this setting cannot achieve one-handed switching on / off and power adjustment. For example, CN218458013U discloses a handheld vacuum cleaner with a speed control unit on its touch screen to control the motor speed. Similarly, users cannot adjust the power with one hand while holding the handle. Both of these solutions require users to adjust their posture and use the other hand to complete the switching on / off or power adjustment, and the flexibility and convenience of use need to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum cleaner with a speed adjustment mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0017] 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.

[0018] like Figure 1-5The vacuum cleaner shown includes a speed-adjustable mechanism, comprising a body 1, which houses a drive unit that generates vacuum suction for dust collection. A handle 11 is located at the rear of the body 1, with a main switch 111 controlling the opening and closing of the device inside the handle 11. A support base 12 is formed below the handle 11, which can house or connect to a battery unit that powers the drive unit. A horizontal support 2 is formed at the front of the body 1, with a detachable dust cup 3. An air inlet pipe 21 is integrally formed on the support 2, communicating with the dust cup 3. When a vacuuming accessory is connected to the air inlet pipe 21, the vacuum suction collects and stores the collected dust. The dust is stored in the dust cup 3. To facilitate one-handed speed adjustment, a speed adjustment mechanism is slidably connected to the rear side of the support 2. The speed adjustment mechanism includes a slide rod 4, a return spring 5, and a micro switch 6. A pull ring 41 is formed at the rear end of the slide rod 4. The pull ring 41 is set close to the main switch 111 for easy one-handed control. The slide rod 4 is abutted against the support 2 by the return spring 5. A drive block 42 for triggering the micro switch 6 is formed at the top of the slide rod 4. The micro switch 6 is fixed inside the support 2 and is electrically connected to the circuit board 7 located in the support base 12 through a wire (not shown in the figure). When the pull ring 41 is pulled, the drive block 42 triggers the micro switch 6, and the circuit board 7 adjusts to the corresponding power level according to the number of triggers.

[0019] Furthermore, the support 2 has a bolt positioning post 22 and a baffle 23 inside. The front side of the slide rod 4 has a collar 43 that is slidably sleeved on the bolt positioning post 22. That is, the bolt positioning post 22 limits the forward and backward sliding of the slide rod 4. The rear end of the collar 43 forms a spring guide post 431. The return spring 5 abuts between the spring guide post 431 and the baffle 23. Thus, when the pull ring 41 is pulled, the return spring 5 is compressed, the drive block 42 collides with the micro switch 6, and when the pull ring 41 is released, the return spring 5 automatically rebounds and resets, and the drive block 42 disengages from the micro switch 6.

[0020] Furthermore, a support cover 24 is provided above the support 2. The support cover 24 has a bolt post 241 inserted into the bolt positioning post. The bolt post 241 and the bolt positioning post 22 are connected by bolts 8, thereby fixing the support cover 241 to the support 2. The slide rod 4 is enclosed in the space enclosed by the support cover 241 and the support 2, and moves horizontally under the limit of the bolt positioning post 22.

[0021] Furthermore, the support 2 and the support base 12 are connected by a support column 13, which is roughly parallel to the handle 11. The wires connecting the micro switch 6 and the circuit board 7 are routed through the inside of the support column 13.

[0022] Furthermore, the bracket 2 has a latch 25 and a latch button 26 for locking the dust cup 3. The bottom of the dust cup 3 is provided with a corresponding locking block 31. Inserting the locking block 31 into the latch 25 will automatically lock the dust cup 3. Pressing the latch button 26 will release the dust cup 3. This locking method is existing technology and will not be described in detail.

[0023] Furthermore, the upper end of the support 2 has an air outlet 27 connected to the air inlet pipe 21, and the dust cup 3 has an air inlet opening 32 corresponding to the air outlet 27. When the dust cup 3 is locked in the support 2, the two automatically connect and communicate.

[0024] The working principle and usage process of this utility model are as follows: Select a suitable dust collection attachment according to the working environment, connect it to the air inlet pipe 21, hold the handle 11 with one hand, press the main switch 111 to start the drive unit, and under the action of vacuum suction, the dust-laden airflow enters the dust cup 3 through the dust collection attachment. After being filtered by the filter screen inside the dust cup 3, the dust and dirt are left in the dust cup 3, and the clean airflow is discharged.

[0025] When the vacuum suction needs to be increased or decreased, the pull ring 41 can be pulled with one hand. Each pull ring is pulled, and the circuit board 7 is adjusted to a corresponding power level. For example, the circuit board 7 is set with three increasing power levels. When the machine is started, it is in the initial level with the lowest power. After pulling the pull ring twice, it can be raised to the highest level, at which time the vacuum suction is the greatest. After pulling the pull ring a third time, it returns to the initial level. The power level can be adjusted in this cycle. By adjusting the power level, a suitable vacuum suction can be selected to meet different cleaning needs. Preferably, a display screen 14 can be set on the rear side of the main body 1 above the handle 11. The display screen 14 can show the power level adjustment status, so that the user can view and make corresponding adjustments.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
