Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to an oblique cyclone airflow guide mechanism for vacuum cleaners. Background Technology

[0002] Vacuum cleaners are a common household cleaning appliance. Common vacuum cleaners can be broadly categorized by their structure into canister, upright, and handheld types. Canister vacuum cleaners consist of the main body, vacuum fan, connecting hose, and floor brush. The vacuum fan is installed inside the main body and connects to the floor brush via a flexible hose. During use, the floor brush is operated to vacuum, and the main body is moved by dragging it through the connecting hose. Canister vacuum cleaners are generally large, requiring frequent dragging, making them less convenient to operate. Upright vacuum cleaners have an integrated floor brush and vacuum fan structure. Vacuuming is done by simply pushing the main body, making them ideal for cleaning floors. However, when cleaning walls, furniture surfaces, and tabletops, the entire vacuum cleaner needs to be lifted, which is inconvenient.

[0003] Handheld vacuum cleaners are designed for portability, being small and lightweight, easy for users to operate, and have a wider range of applications. To guide dust-laden airflow quickly into the dust cup, a deflector is usually installed inside the vacuum cleaner's airflow tube. Existing deflectors consist of multiple ring-shaped deflector plates, with air intake channels formed between pairs of adjacent plates. The deflector plates are angled to create a vortex to guide the airflow quickly into the dust cup. However, the placement of these deflector plates often allows external debris, such as hair, to get caught on them, causing blockages inside the airflow tube and affecting the vacuum cleaner's operation.

[0004] Therefore, there is a need to provide an oblique cyclone airflow duct mechanism for vacuum cleaners to solve the above problems. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an oblique cyclone airflow guiding duct mechanism for a vacuum cleaner, which can guide the airflow carrying garbage and dust into the dust cup quickly, avoid the phenomenon of garbage and hair accumulating and clogging the guiding channel during the use of the vacuum cleaner, and improve the guiding efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an oblique cyclone airflow guiding duct mechanism for a vacuum cleaner, corresponding to the position of the dust cup on the vacuum cleaner, and capable of guiding the airflow entering the dust cup, including an air inlet pipe and an air guide pipe detachably connected to it along a first direction; the air inlet channel inside the air inlet pipe is interconnected with the interior of the air guide pipe to form a through channel for airflow, the air guide pipe includes a pipe body one and a pipe body two connected at an angle, the air guide channel one inside the pipe body one is connected to the air guide channel two inside the pipe body two, the axis of the air guide channel two is set at an inclined angle in a first plane, and the axis of the air guide channel one and the axis of the air inlet channel form an angle one, so that the airflow in the through channel is spirally guided into the dust cup, and the inclination angle of the axis of the air guide channel two and the included angle one are both acute angles.

[0007] Furthermore, the first pipe body is located between and connects the air inlet pipe and the second pipe body. The air inlet pipe includes an opposing air inlet end and a connecting end one. The end of the first pipe body closest to the air inlet pipe is the connecting end two. The connecting end one and the connecting end two are detachably connected, facilitating user disassembly, replacement, or cleaning.

[0008] Furthermore, the first and second tubes are integrally formed, and the end where the first and second tubes connect is arc-shaped. The end of the second tube away from the first tube is the air outlet, and the air outlet port is equipped with a sealing element. The air outlet on the second tube fits into the air inlet on the dust cup, so that the airflow in the guide tube can be smoothly guided into the dust cup. The sealing element ensures that the airflow will not escape into the air from the contact point between the guide tube and the dust cup during the process of guiding the airflow to the dust cup, preventing dust from spreading again and ensuring the cleaning effect of the vacuum cleaner.

[0009] Furthermore, the first connection end and the second connection end are interference-fitted together.

[0010] Furthermore, the angle between the air guide channel and the air inlet channel is 19.5 degrees.

[0011] Furthermore, the axis of the second air guide channel has an inclination angle of 19.5 degrees in the first plane. This inclination creates a slanted vortex inside the air guide duct, allowing the airflow to be spirally accelerated and obliquely guided into the dust cup.

[0012] Furthermore, a dust detection component is symmetrically arranged on the air duct along its axis. The dust detection component includes a mounting plate and a mounting seat that passes through the inner wall of one side of the air duct and is inserted therein. The mounting plate has a first end and a second end that are opposite each other. A sensor is fixedly mounted on the first end, and the second end is detachably connected to the outer wall of the air duct. The end of the sensor away from the mounting plate can be movably inserted into a receiving part opened on the mounting seat.

[0013] Furthermore, the mounting base also includes a plug-in portion arranged around the receiving portion, which can be interference-fitted with the plug-in groove on the air duct. The outer wall of the air duct is also provided with a fixing member, each of which has a locking hole. The second end of the mounting plate has a threaded slot that matches the locking hole. The locking screw can pass through the threaded slot and the locking hole in sequence to lock the mounting plate onto the air duct. The mounting base is made of transparent material.

[0014] The beneficial effects of this utility model are: In this invention, the air inlet pipe and the air guide pipe work together. The first pipe body on the air guide pipe is inclined relative to the air inlet pipe, and the second tank body on the air guide pipe is also inclined relative to the first pipe body. This makes the internal airflow channel form an oblique flow guide, so as to guide the airflow carrying garbage and dust into the dust cup quickly. Both the air inlet pipe and the air guide pipe have smooth inner walls, which can effectively avoid the phenomenon of garbage and hair accumulating and blocking the flow channel during the use of the vacuum cleaner, thus improving the flow efficiency.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] See appendix Figures 1 to 5As shown, this embodiment of the inclined cyclone airflow guiding duct mechanism for a vacuum cleaner corresponds to the position of the dust cup on the vacuum cleaner and can guide the airflow entering the dust cup. It includes an air inlet pipe 1 and an air guide pipe 2 detachably connected to it along a first direction. The air inlet channel inside the air inlet pipe 1 is interconnected with the interior of the air guide pipe 2 to form a through channel for airflow. The air inlet channel is opened inside the air inlet pipe 1 along the length direction of the air inlet pipe 1 and passes through both ends of the air inlet pipe 1. The air guide duct 2 includes a pipe body 23 and a pipe body 24 connected at an angle. The air guide channel 1 in the pipe body 23 is connected to the air guide channel 2 in the pipe body 24. The axis of the air guide channel 2 is set at an angle in a first plane. The axis of the air guide channel 1 and the axis of the air inlet channel form an angle 1, so that the airflow in the through channel is spirally guided into the dust cup. The angle of inclination of the axis of the air guide channel 2 and the angle 1 are both acute angles. The tilt angles of pipe body 1 (23) and pipe body 2 (24) cause the airflow within the through channel to flow in a spiral shape. This spiral airflow generates stable angular momentum, which significantly improves the speed of the airflow compared to the direct current airflow generated by a regular straight pipe. This better guides the airflow carrying garbage and dust into the dust cup quickly. Furthermore, compared to the prior art where a guide vane is installed in the air duct 2 to guide the airflow, both the air inlet pipe 1 and the air duct 2 in this application have smooth inner walls, which effectively prevents garbage and hair from accumulating and clogging the airflow channel during vacuum cleaner use, thus improving airflow efficiency.

[0018] See appendix Figure 1 The connection between the air inlet duct 1 and the air guide duct 2 can be achieved through an interference fit, facilitating user disassembly, replacement, or cleaning. In some embodiments, a first duct body 23 is located between and connects the air inlet duct 1 and a second duct body 24. The air inlet duct 1 includes an opposing air inlet end 11 and a first connecting end 12. The end of the first duct body 23 closest to the air inlet duct 1 is a second connecting end 21, and the first connecting end 12 and the second connecting end 21 are detachably connected. Specifically, the first connecting end 12 and the second connecting end 21 can be an interference fit.

[0019] In some embodiments, tube body 23 and tube body 24 are integrally formed, and the end of tube body 23 that connects to tube body 24 is arc-shaped. The end of tube body 24 away from tube body 23 is the air outlet 22, and the air outlet 22 is provided with a sealing element 3. The air outlet 22 on tube body 24 fits into the air inlet on the dust cup so that the airflow in the air guide tube 2 can be smoothly guided into the dust cup. The arc-shaped part on tube body 23 makes the airflow in the air guide tube 2 smoother and avoids sharp corners causing debris blockage or snagging hair. The sealing element 3 ensures that the airflow will not escape into the air from the contact point between the air guide tube 2 and the dust cup during the process of guiding the airflow to the dust cup, preventing dust from spreading again and ensuring the cleaning effect of the vacuum cleaner.

[0020] See appendix Figure 3 In some embodiments, the first plane refers to the plane where the Z-axis is located, as shown in the figure. The straight line containing the Z-axis in the figure intersects the axis of the air guide channel, forming an angle two. Specifically, the end of the air guide channel two that is away from the air guide channel one is inclined towards the direction closer to the Y-axis, that is, the air guide channel two is inclined to the right side of the air guide channel one in the figure, and the angle of inclination is the aforementioned angle two.

[0021] In some embodiments, the included angle 2 is set to 19.5 degrees, and the included angle 1 formed between the air guide channel 1 and the air inlet channel can also be 19.5 degrees. With the above-mentioned tilting arrangement, an oblique cyclone can be formed inside the air guide duct 2, thereby allowing the airflow to be spirally accelerated and obliquely guided into the dust cup.

[0022] See appendix Figure 2 The angle between the air guide channel 1 and the air inlet channel is 19.5 degrees. Specifically, the axis of the air inlet channel is set horizontally along the X-axis, and the axis of the air guide channel 1 is offset upward by 19.5 degrees along the axis of the air inlet channel, so that the horizontal straight air in the air inlet duct 1 enters the air guide duct 2 at an angle.

[0023] See appendix Figures 4 to 5 A dust detection component 4 is symmetrically arranged on the air duct 2 along its axis. The dust detection component 4 includes a mounting plate 43 and a mounting base 41 that passes through the inner wall of one side of the air duct 2 and is inserted thereon. The mounting plate 43 has a first end and a second end that are opposite each other. A sensor 42 is fixedly mounted on the first end, and the second end is detachably connected to the outer wall of the air duct 2. The end of the sensor 42 that is away from the mounting plate 43 can be movably inserted into the receiving part 411 opened on the mounting base 41.

[0024] The mounting base 41 also includes a plug-in portion 412 surrounding the receiving portion 411. The plug-in portion 412 can be interference-fitted with the plug-in groove on the air duct 2. The outer wall of the air duct 2 is also provided with a fixing member 44. Each fixing member 44 has a locking hole 45. The second end of the mounting plate 43 has a threaded slot that matches the locking hole 45. The locking screw can pass through the threaded slot and the locking hole 45 in sequence to lock the mounting plate 43 onto the air duct 2. The mounting base 41 is made of transparent material. On the one hand, the transparent material ensures that it will not interfere with the sensing of the sensor 42 located on it, thus ensuring the effectiveness of dust detection. On the other hand, the plug-in structure of the mounting base 41 also ensures that after long-term use, there will be no dust leakage compared to the sensor 42 being directly plugged into the air duct 2.

[0025] The receiving part 411 is used for the horizontal placement of the sensor 42. The insertion part 412 is interference-fitted with the insertion slot on the air duct 2, thereby ensuring that no dust inside the air duct 2 will escape from the gap between the two and out of the air duct 2, thus avoiding the phenomenon of dust running from the nozzle and ensuring the cleaning effect.

[0026] The mounting plate 43 is connected to the fixing piece 44 by tightening screws, so that the sensor 42 and the air duct 2 can be detached, which facilitates the replacement of the sensor 42.

[0027] The two sensors 42 are through-beam sensors 42, one of which is the transmitter and the other is the receiver.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
