Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaner cone structure, and in particular to a vacuum cleaner and its inner cone structure. Background Technology

[0002] As a common household cleaning device, the noise level of vacuum cleaners has always been a major concern for users. Traditional vacuum cleaners generate significant noise during operation due to the high-speed rotation of the motor and the airflow, impacting the user experience. In recent years, with rising demands for quality of life, the market demand for low-noise vacuum cleaners has been growing. Currently, some vacuum cleaners on the market have reduced noise by improving motor design or adding sound insulation materials, but these methods are often costly or have limited effectiveness. Furthermore, the noise generated by airflow within the vacuum cleaner is also a significant factor affecting the overall noise level, but there are currently few optimization measures specifically addressing airflow noise. The inner cone of the vacuum cleaner is a key component for efficiently separating dust and air, and its design directly affects dust separation efficiency.

[0003] A search revealed Chinese Patent Publication No. CN113303701A, which discloses a vacuum cleaner comprising: a garbage separator and a fan chamber; the garbage separator includes at least: a dust bin, a separator, and a first filter; the dust bin has a fluid inlet and a fluid outlet, the first filter is located at the fluid outlet, the separator is located inside the dust bin and near the fluid outlet, and the separator has multiple ventilation holes extending through it; the fan chamber is connected to the fluid outlet of the dust bin, and a fan and a second filter are installed inside the fan chamber; the fluid inlet, separator, fluid outlet, first filter, fan, and second filter are arranged sequentially along the separator. The invention optimizes the internal structure of the garbage separator and the fan chamber to minimize the flow path of fluid within the vacuum cleaner, thereby reducing pressure drop and improving the separation efficiency of the garbage separator. Existing bagless vacuum cleaners generally use cyclone separation technology, which uses centrifugal force generated by high-speed rotating airflow to separate dust from air. As users' performance requirements for vacuum cleaners increase, improving the separation efficiency of fine dust has become a technological hotspot. However, the design of the inner cone shape and airflow channel limits the timely removal of fine dust particles. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a vacuum cleaner and its inner cone structure, which aims to improve the problem in the prior art that fine dust cannot be thrown out in time due to the limitations of the inner cone shape and airflow channel design.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum cleaner and its inner cone structure, comprising a body, a motor fixedly connected to the rear end of the inner side of the body, a spiral impeller fixedly connected to the output end of the motor, a partition plate fixedly connected to the middle inner side of the body, a cone wall fixedly connected to the front side of the partition plate, a cone-shaped body fixedly connected to the middle front side of the partition plate, a plurality of spiral grooves equally spaced on the outer wall of the cone-shaped body, a filter cotton pad fixedly connected to the inner side of the partition plate, and a convenient replacement mechanism installed on the front side of the body for quickly replacing the vacuum nozzle.

[0006] The above technical solution involves a motor driving the rotation of a spiral impeller. As the impeller rotates, it creates negative pressure within the machine, generating strong suction. This suction draws dust into the machine, where it collides with a cone-shaped object fixed in front of a partition plate. The cone divides the dust-laden airflow. The funnel-shaped design of the cone, combined with spiral grooves, forces the airflow into a narrower channel, increasing airflow velocity and creating stronger centrifugal force. This makes it easier for fine dust particles to be thrown against the cone wall. The inclined wall of the cone, along with the spiral grooves, guides the airflow along a fixed spiral trajectory, preventing turbulence from interfering with the separation process. The dust-laden airflow enters the converging section from the inlet, where the dust, under centrifugal force, adheres tightly to the cone wall and slides down. Clean air exits from the outlet, and the dust finally falls into the dust collection device. The filter pad then performs secondary filtration on the separated air.

[0007] As a further description of the above technical solution:

[0008] The convenient replacement mechanism includes a hose, the rear end of which is connected to the upper front end of the body. The end of the hose is fixedly connected to a housing. Multiple fixing buckles are equidistantly slidably connected to the rear inner side of the housing. An adjustment disc is rotatably connected to the front inner side of the housing. An adjustment ring is fixedly connected to the front end of the adjustment disc. A vacuum head is slidably connected to the inner side of the housing.

[0009] The above technical solution involves rotating the adjusting ring, which causes the adjusting disc installed inside the housing to rotate synchronously. When the adjusting disc rotates inside the housing, it drives the corresponding fixing buckle to slide outward inside the housing through the guide groove on it. Then, the hose is grasped and the vacuum head is pulled out. A new vacuum head is then inserted into the housing. The adjusting ring is then rotated in the opposite direction, causing the adjusting disc to rotate in reverse inside the housing. This causes the corresponding fixing buckle to slide in opposite directions inside the housing through the guide groove on the adjusting disc, thereby fixing the new vacuum head.

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

[0011] A stabilizing frame is fixedly connected to the bottom of the motor, and screws are threaded to the left and right sides, front and rear ends of the stabilizing frame.

[0012] The above technical solution, which uses a stabilizer bracket secured with screws, can improve the stability of the motor.

[0013] As a further description of the above technical solution:

[0014] Multiple exhaust holes are equidistantly provided on the left and right sides of the top rear side of the machine body, and a filter screen is fixedly connected to the inside of each of the multiple exhaust holes.

[0015] The above technical solution allows the filter screen fixed in the exhaust port to filter the air passing through the exhaust port.

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

[0017] A rubber sleeve is fixedly connected to the outer wall of the adjusting ring, and the outer wall of the rubber sleeve is provided with anti-slip texture.

[0018] The above technical solution improves the friction of the rubber sleeve fixed outside the adjusting ring by creating anti-slip textures on its surface.

[0019] As a further description of the above technical solution:

[0020] A knob is rotatably connected to the top front right end of the machine body, and an indicator light is fixedly connected to the top front left end of the machine body.

[0021] The above technical solution allows users to control the vacuum cleaner's speed settings via a knob, while indicator lights are used to observe the vacuum cleaner's status.

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

[0023] A dust collection box is slidably connected to the middle right side of the machine body, and a pull ring is rotatably connected to the right side of the dust collection box.

[0024] The above technical solution allows for easy cleaning of the dust collected inside the machine by using a pull ring to move the dust collection box.

[0025] As a further description of the above technical solution:

[0026] Bearings are fixedly connected to the four corners at the bottom of the machine body, and rollers are fixedly connected to the bottom of each bearing.

[0027] The above technical solution facilitates the movement of the machine body by using rollers fixed under the machine body with bearings.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor drives the spiral impeller to rotate and generate suction. As this suction draws dust into the machine body, it collides with the cone-shaped body fixed in front of the partition plate. The cone-shaped body, together with the spiral groove, forces the airflow into a narrower channel, thereby increasing the airflow speed and forming a stronger centrifugal force. This makes it easier for fine dust to be thrown against the cone wall. After the airflow is accelerated through the converging section, it maintains a uniform rotation speed in the steady flow section. The dust is pressed against the cone wall and slides down under the action of centrifugal force. Clean air is discharged from the outlet, and the dust finally falls into the dust collection device. The filter cotton pad will perform secondary filtration on the separated air, thereby achieving the separation effect of dust.

[0030] 2. In this utility model, the adjusting ring drives multiple fixing buckles to slide outward through the adjusting disc. Then, the vacuum head is pulled out by grasping the hose, and a new vacuum head is inserted into the outer shell. The adjusting ring drives the adjusting disc to rotate in the opposite direction, thereby driving multiple fixing buckles to slide in opposite directions, thus fixing the new vacuum head. This achieves the effect of quick replacement of the vacuum head. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a vacuum cleaner and its inner cone structure, including a body 1. A motor 3 is fixedly connected to the rear end of the inner side of the body 1. A spiral impeller 4 is fixedly connected to the output end of the motor 3, and the motor 3 drives the spiral impeller 4 to rotate. A partition plate 5 is fixedly connected to the middle of the inner side of the body 1. A cone wall 6 is fixedly connected to the front side of the partition plate 5, and the partition plate 5 is used to fix the cone wall 6. A cone 7 is fixedly connected to the middle of the front side of the partition plate 5. A plurality of spiral grooves 8 are equidistantly formed on the outer wall of the cone 7, and the cone 7 is guided through the spiral grooves 8. Air is guided through the partition plate 5, and a filter cotton pad 9 is fixedly connected to the inner side of the partition plate 5. A convenient replacement mechanism 2 is installed on the front side of the body 1. The convenient replacement mechanism 2 is used to quickly replace the suction nozzle. A stable frame 10 is fixedly connected to the bottom of the motor 3. Screws 11 are threadedly connected to the front and rear ends of the left and right sides of the stable frame 10. The screws 11 are used to fix the stable frame 10. Multiple exhaust holes 12 are equally spaced on the left and right ends of the rear top of the body 1. A filter screen 13 is fixedly connected to the inner side of the multiple exhaust holes 12. The filter screen 13 fixed in the exhaust hole 12 is used to filter dust.

[0040] Specifically, motor 3 provides power to drive the rotation of the spiral impeller 4. When the spiral impeller 4 rotates, it creates a negative pressure inside the machine body 1, thereby generating a strong suction force. As this suction force draws dust into the machine body 1, it collides with the cone 7 fixed in front of the partition plate 5. The cone 7 divides the airflow carrying dust. The funnel-shaped design of the cone 7, combined with the spiral groove 8, forces the airflow into a narrower channel, thereby increasing the airflow speed and creating a stronger centrifugal force, making it easier for fine dust to be thrown towards the cone wall 6. The inclined wall of the cone 7, combined with the spiral groove 8, guides the airflow. Rotating along a fixed spiral trajectory, the dust-laden airflow enters the converging section from the air inlet to avoid turbulence interfering with the separation process. The guide ribs force the airflow to form a stable spiral trajectory. After the airflow is accelerated through the converging section, it maintains a uniform rotation speed in the steady flow section. The dust is pressed against the cone wall 6 and slides down due to centrifugal force, while clean air is discharged from the outlet. The dust finally falls into the dust collection device, and the filter cotton pad 9 performs secondary filtration on the separated air. The stabilizing frame 10, which is fixed by screws 11, can improve the stability of the motor 3. The filter screen 13, which is fixed in the exhaust hole 12, can filter the air passing through the exhaust hole 12.

[0041] Reference Figure 4 and Figure 5 The convenient replacement mechanism 2 includes a hose 201. The rear end of the hose 201 is connected to the upper front end of the body 1. The end of the hose 201 is fixedly connected to the outer shell 202. The hose 201 is used to fix the outer shell 202. Multiple fixing buckles 203 are equidistantly slidably connected to the rear inner side of the outer shell 202. An adjustment plate 204 is rotatably connected to the front inner side of the outer shell 202. The adjustment plate 204 drives the fixing buckles 203 to slide. An adjustment ring 205 is fixedly connected to the front end of the adjustment plate 204. The adjustment ring 205 drives the adjustment plate 204 to rotate. A vacuum head 206 is slidably connected to the inner side of the outer shell 202. A rubber sleeve 14 is fixedly connected to the outer wall of the adjustment ring 205. The outer wall of the rubber sleeve 14 is provided with anti-slip texture 15. The rubber sleeve 14 improves its anti-slip properties through the anti-slip texture 15.

[0042] Specifically, rotating the adjusting ring 205 causes the adjusting disc 204 installed inside the housing 202 to rotate synchronously. When the adjusting disc 204 rotates inside the housing 202, it drives the corresponding fixing buckle 203 to slide outward inside the housing 202 through the guide groove on it. Then, grasp the hose 201 and pull out the vacuum head 206. Then, insert the new vacuum head 206 into the housing 202. Then, rotate the adjusting ring 205 in the opposite direction. The adjusting ring 205 drives the adjusting disc 204 to rotate in reverse inside the housing 202. This drives the corresponding fixing buckle 203 to slide in opposite directions inside the housing 202 through the guide groove on the adjusting disc 204, thereby fixing the new vacuum head 206. The rubber sleeve 14 fixed outside the adjusting ring 205 increases its friction through the anti-slip texture 15 on its outside.

[0043] Reference Figure 1 and Figure 3 A knob 16 is rotatably connected to the top front right end of the body 1, and an indicator light 17 is fixedly connected to the top front left end of the body 1. The knob 16 and the indicator light 17 are used to operate the vacuum cleaner. A dust collection box 18 is slidably connected to the middle right side of the body 1. A pull ring 19 is rotatably connected to the right side of the dust collection box 18. The pull ring 19 is used to pull the dust collection box 18. Bearings 20 are fixedly connected to the four corners of the bottom of the body 1. Rollers 21 are fixedly connected to the bottom of each bearing 20. The bearings 20 are used to fix the rollers 21.

[0044] Specifically, the vacuum cleaner's speed can be operated via knob 16, while the indicator light 17 is used to observe the vacuum cleaner's status. The dust collection box 18, which can be pulled via pull ring 19, facilitates the cleaning of dust collected inside the body 1. The rollers 21, which are fixed to the bottom of the body 1 via bearing 20, facilitate the movement of the body 1.

[0045] Working Principle: When using the vacuum cleaner, the motor 3 installed in the body 1 first provides power to drive the rotation of the spiral impeller 4. When the spiral impeller 4 rotates, it creates a negative pressure inside the body 1, thereby generating a strong suction force. As this suction force draws dust into the body 1, it collides with the cone 7 fixed in front of the partition plate 5. The cone 7 divides the airflow carrying dust. The funnel-shaped design of the cone 7, combined with the spiral groove 8, forces the airflow into a narrower channel, thereby increasing the airflow speed and creating a stronger centrifugal force. Fine dust particles are more easily thrown towards the cone wall 6. The inclined wall of the cone 7, together with the spiral groove 8, guides the airflow to rotate along a fixed spiral trajectory, avoiding turbulence from interfering with the separation process. The dust-laden airflow enters the tapering section from the air inlet, and the guide ribs force the airflow to form a stable spiral trajectory. After the airflow is accelerated through the tapering section, it maintains a uniform rotation speed in the steady flow section. The dust particles slide down the cone wall 6 under the action of centrifugal force, and the clean air is discharged from the outlet. The dust finally falls into the dust collection device, and the filter cotton pad 9 performs secondary filtration on the separated air, thereby achieving the separation effect of dust.

[0046] When different vacuum heads 206 need to be replaced according to different usage scenarios, first rotate the adjusting ring 205, which will drive the adjusting plate 204 installed in the housing 202 to rotate synchronously. When the adjusting plate 204 rotates in the housing 202, it will drive the corresponding fixing buckle 203 to slide outward in the housing 202 through the guide groove on it. Then, grasp the hose 201 to pull out the vacuum head 206, and then insert the new vacuum head 206 into the housing 202. Then, rotate the adjusting ring 205 in the opposite direction, which will drive the adjusting plate 204 to rotate in reverse in the housing 202. This will drive the corresponding fixing buckle 203 to slide in opposite directions in the housing 202 through the guide groove on the adjusting plate 204, thereby fixing the new vacuum head 206. This achieves the effect of quick replacement of the vacuum head 206.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
