Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and specifically to a dust collection device. Background Technology

[0002] As a core component of modern cleaning tools, the technological evolution of vacuum cleaners has always revolved around key issues such as gas-liquid separation, gas-solid separation, and suction efficiency. However, existing vacuum cleaner technologies suffer from the following significant drawbacks:

[0003] 1. Foam or air bubbles can easily enter the suction generating mechanism. When traditional vacuum cleaners handle liquids containing foam, the light weight of the foam often allows it to enter the suction generating mechanism with the airflow. This can cause component corrosion, short circuits, or even motor burnout, resulting in a shorter service life for the vacuum cleaner.

[0004] 2. When the handheld vacuum cleaner is rotated, liquid can easily enter the suction generating mechanism. When the handheld vacuum cleaner changes position, liquid can easily enter the suction generating mechanism through the suction channel, which can easily damage the suction generating mechanism.

[0005] 3. Cleaning the sludge collection box is relatively troublesome. Utility Model Content

[0006] This utility model addresses the aforementioned problems and aims to provide a vacuuming device that can break up foam in the airflow and prevent liquid from entering the suction generating mechanism through staggered baffles, thereby effectively reducing the amount of liquid entering the suction generating component.

[0007] To achieve the above objectives, this utility model provides a vacuuming device, including a vacuuming execution component, a separation component, and a suction generating component. The vacuuming execution component includes a vacuuming head, a vacuuming channel, and a sludge collection box. One end of the vacuuming channel is connected to the vacuuming head, and the other end extends into the sludge collection box. The separation component includes a first separation tube and a second separation tube arranged in the sludge collection box. The suction generating component is used to provide suction power that passes sequentially through the second separation tube, the sludge collection box, the first separation tube, and the vacuuming channel.

[0008] The first end of the second separation tube is connected to the suction generating component, the second end of the second separation tube is provided with a first inlet communicating with the sludge storage box, and the second separation tube is provided with a part to be impacted.

[0009] The first end of the first separation tube is connected to the dust suction channel, and the second end of the first separation tube is provided with a first outlet connected to the sludge storage box. The first outlet is disposed opposite to the part to be impacted and is used to guide gas to impact the part to be impacted in order to break the foam in the gas.

[0010] According to the above-described vacuuming device, the part to be impacted is a positioning ring, which is an annular protrusion structure and located outside the first end of the second separation tube. The second separation tube is connected to the suction generating component through the positioning ring. The first outlet is located on one side of the positioning ring and faces the outer wall of the positioning ring.

[0011] According to the above-described dust collection device, a second outlet is provided on the second end of the first separation tube. The second outlet is arranged on the opposite side of the first outlet. The second outlet is a conical hole, and the flared end of the second outlet faces the sludge storage box.

[0012] According to the above-described dust collection device, the second separation tube is located on one side of the first separation tube, and the first inlet and the first outlet are arranged in a staggered manner on the front and rear sides of the sludge storage box.

[0013] According to the above-described dust collection device, the second end of the second separation tube is provided with an air inlet channel, the first inlet is located at one end of the air inlet channel, and the air inlet channel is also provided with a first partition and a second partition, the first partition and the second partition being arranged alternately in the air inlet channel in a vertical direction;

[0014] A slot is provided on the second separation pipe at the top of the first inlet, and the slot is connected to the air inlet channel.

[0015] According to the above-described vacuuming device, the first partition is arranged at the lower part of the first inlet and is attached to both sides of the first inlet, and the second partition is arranged at the upper part of the second separation tube and is attached to both sides of the second separation tube.

[0016] According to the above-described vacuuming device, the sludge storage box is provided with a front cover and a rear cover. Both the front cover and the rear cover are detachably mounted on the sludge storage box, and the front cover and the rear cover can be removed separately to expose the interior of the sludge storage box.

[0017] According to the above-described vacuuming device, the vacuuming channel is provided in two sets, the first separation tube is provided in two sets, the two sets of first separation tubes are respectively connected to the two sets of vacuuming channels, and the two sets of first separation tubes are symmetrically arranged on both sides of the second separation tube.

[0018] The vacuuming device described above further includes a housing assembly, which includes a housing and a handle fixed to the housing. The vacuuming channel and the suction generating component are both installed inside the housing.

[0019] According to the above-described vacuuming device, the suction generating component includes a motor and an impeller. The motor is fixed inside the housing, the impeller is mounted on the output shaft of the motor, and the suction generated by the impeller can be transmitted to the sludge storage box through the second separation pipe.

[0020] This utility model has the following beneficial effects:

[0021] 1. When sucking up liquids or soapy liquids containing foam, a large amount of foam or bubbles will be generated in the first separation tube. When it enters the sludge storage box through the first outlet, a large amount of foam and bubbles will directly hit the positioning ring with the airflow, which will cause a large amount of foam and bubbles to burst, greatly reducing the content of foam and bubbles in the airflow, and can greatly reduce the amount of foam and bubbles entering the suction generating component.

[0022] 2. A second outlet is also provided on the first separation tube to ensure the suction provided by the first separation tube. At the same time, the second outlet is set as a conical hole with the flared end facing the sludge storage box. When the airflow and liquid are discharged into the sludge storage box through the second outlet, the foam or bubbles in the airflow have an edge-adhering effect, that is, the foam and bubbles will become larger. The foam and bubbles can also be broken, which not only ensures the suction effect, but also reduces the content of foam and bubbles in the airflow, and also reduces the amount of foam in the suction generating component.

[0023] 3. The air inlet channel of the second separation tube is equipped with a first baffle and a second baffle arranged in a staggered manner. No matter which way the user holds the vacuum cleaner, there is a corresponding baffle to prevent liquid from entering the suction generating component, which can effectively improve the service life of the suction generating component.

[0024] 4. A slot is provided at the top of the first inlet to ensure that the second separation tube provides sufficient suction and to prevent the suction from being reduced due to the presence of the partition.

[0025] 5. The waste collection box is equipped with a removable front cover and a rear cover, which can be removed separately for easy cleaning and maintenance. Attached Figure Description

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] like Figure 1-5 As shown, a vacuuming device includes a vacuuming execution component 100, a separation component 200, and a suction generating component 300. The suction generating component 300 provides suction, which is transmitted to the vacuuming execution component 100 through the separation component 200 to suck up debris. The vacuuming execution component 100 performs the vacuuming action, while the separation component 200 separates gas and liquid or gas and solid, so that the liquid or solid can be retained in the vacuuming execution component 100, while the gas mixture can be discharged from the suction generating component 300, thereby ensuring the air pressure balance in the vacuuming execution component 100.

[0038] Specifically, the vacuuming execution assembly 100 includes a vacuum head 110, a vacuum channel 120, and a sludge collection box 130. One end of the vacuum channel 120 is connected to the vacuum head 110, and the other end extends into the sludge collection box 130. The separation assembly 200 includes a first separation tube 210 and a second separation tube 220 arranged within the sludge collection box 130. The suction generating assembly 300 is used to increase the suction force as the vacuum passes through the second separation tube 220, the sludge collection box 130, the first separation tube 210, and the vacuum channel 120 in sequence. The suction force is transmitted from the vacuum channel 120 to the vacuum head 110. After the head 110, the suction head 110 can suck in the garbage, and then the garbage is transferred to the first separation tube 210 through the suction channel 120. The first separation tube 210 performs preliminary gas-liquid separation or gas-solid separation on the garbage, so that the liquid or solid is retained in the sludge collection box 130. Then the gas can be discharged from the suction generating component 300 through the second separation tube 220. The function of the second separation tube 220 is to prevent the solid or liquid in the sludge collection box 130 from entering the suction generating component 300, and to protect the suction generating component 300.

[0039] In this embodiment, the first end of the second separation tube 220 is connected to the suction generating component 300. The second end of the second separation tube 220 is provided with a first inlet 222 communicating with the sludge storage box 130, and a part to be impacted is provided on the second separation tube 220. The first end of the first separation tube 210 is connected to the dust collection channel 120, and the second end of the first separation tube 210 is provided with a first outlet 211 communicating with the sludge storage box 130. The first outlet 211 is arranged opposite to the part to be impacted and is used to guide the gas to impact the part to be impacted in order to break the foam in the gas. That is, when sucking up garbage with foam, such as soap liquid, a large amount of foam will be generated in the dust collection channel 120 and the first separation tube 210 during the suction process. If the foam continues to move with the airflow, a large amount of foam will enter the dust collection channel 120 and the first separation tube 210. In the suction generating component 300, prolonged dampness can lead to component corrosion, short circuits, and even burnout of the motor 310. Therefore, in this embodiment, the first outlet 211 of the first separation pipe 210 is located on one side of the impact part. When gas and liquid or solid are discharged from the first outlet 211 together, the liquid or solid falls into the sludge collection box 130 due to its own gravity. However, a large amount of foam moves with the gas, causing a large amount of foam to impact the impact part. This causes a large amount of foam to burst and revert to liquid, falling into the sludge collection box 130. This significantly reduces the foam content in the gas, greatly reducing the amount of foam entering the suction generating component 300 and improving the service life of the suction generating component 300.

[0040] Therefore, in this embodiment, the vacuum cleaner is suitable for cleaning liquid waste that can produce foam, such as soap solution.

[0041] In this embodiment, an additional suction duct can be drawn out from the suction generating component 300, and the second separation pipe 220 can be connected to the end of the suction duct through its first end, thereby realizing the directional transmission of suction.

[0042] The impact-bearing part is configured as a positioning ring 221. The positioning ring 221 is an annular protrusion structure located outside the first end of the second separation pipe 220. The second separation pipe 220 is connected to the suction generating component 300 through the positioning ring 221. That is, the diameter of the positioning ring 221 is larger than the diameter of the first end of the second separation pipe 220, ensuring that the connection between the positioning ring 221 and the suction pipe does not affect the normal passage of the second separation pipe 220, thus guaranteeing suction. In other words, the positioning ring 221 can both connect to the suction generating component 300 and achieve... The first outlet 211 is used to burst the foam in the gas discharged from the first outlet 211. At the same time, its protrusion can also make the first outlet 211 closer to the positioning ring 221. In this embodiment, the first outlet 211 is located on one side of the positioning ring 221 and the first outlet 211 faces the outer wall of the positioning ring 221, thereby ensuring that the gas coming out of the first outlet 211 will directly rush towards the positioning ring 221. Moreover, since the positioning ring 221 and the first inlet 222 are located at the two ends of the second separation tube 220 respectively, the first outlet 211 and the first inlet 222 can be staggered.

[0043] Of course, in another preferred embodiment, the part to be impacted can also be any part on the second separation tube, as long as it can correspond to the first outlet.

[0044] Furthermore, because the foam needs to be broken, the first outlet 211 cannot be too large; its diameter cannot exceed the width of the positioning ring 221. Otherwise, some foam in the gas will remain, resulting in limited suction provided by the first separation tube 210 and insufficient suction. To solve this problem, a second outlet 212 is provided at the second end of the first separation tube 210. The second outlet 212 can also provide outlets for gas and waste, increasing the overall suction. The second outlet 212 is located on the opposite side of the first outlet 211 and is a conical hole with its flared end facing the sludge storage box 130. That is, the second outlet 212 gradually increases in size from the inside out. Since foam usually has a certain degree of adhesion, it will adhere to the side wall of the second outlet 212. However, as the second outlet 212 gradually increases, the foam will gradually increase until it breaks, thus achieving the purpose of breaking the foam. This achieves both the purpose of increasing suction and ensuring that the foam in the gas can be fully broken.

[0045] Furthermore, to further prevent foam in the liquid or gas from directly entering the second separation tube 220, in this embodiment, the second separation tube 220 is located on one side of the first separation tube 210. The first inlet 222 and the first outlet 211 are misaligned on the front and rear sides of the sludge storage box 130, that is, the first inlet 222 is far away from the first outlet 211, which can prevent foam in the liquid or gas coming out of the first outlet 211 from falling directly into the first inlet 222, thereby further improving the separation effect of the separation component 200.

[0046] Furthermore, an air inlet channel is provided at the second end of the second separation pipe 220, and the first inlet 222 is located at one end of the air inlet channel. The air inlet channel is also provided with a first baffle 224 and a second baffle 225. The first baffle 224 and the second baffle 225 are arranged alternately in the vertical direction in the air inlet channel. The function of the first baffle 224 and the second baffle 225 is to prevent the liquid in the sludge storage box 130 from entering the second separation pipe 220 along the first inlet 222. The alternate arrangement of the first baffle 224 and the second baffle 225 allows the first baffle 224 and the second baffle 225 to work alternately when the dust collection device changes direction, thereby avoiding the second separation pipe 220 from easily entering liquid due to the change of direction.

[0047] In this embodiment, in order to improve the suction provided by the second separation pipe 220, a slot 223 is also provided on the second separation pipe 220 at the top of the first inlet 222. The slot 223 is connected to the air inlet channel. The presence of the slot 223 can increase the opening of the first inlet 222 and ensure that its suction is sufficient.

[0048] Furthermore, the first partition 224 is arranged at the lower part of the first inlet 222 and is attached to both sides of the first inlet 222. That is, the first partition 224 can block the lower part of the first inlet 222, preventing liquid from entering the air intake channel from the lower part of the first inlet 222 when used in the forward direction. The second partition 225 is arranged at the upper part of the second separation pipe 220 and is attached to both sides of the second separation pipe 220. That is, the second partition 225 can block the upper part of the air intake channel. Even if the vacuum cleaner is reversed, the second partition 225 can still prevent liquid from entering the suction generating component 300 from the air intake channel.

[0049] Furthermore, the suction channel 120 is provided in two sets, that is, the two sets of suction channels 120 simultaneously provide suction to the suction head 110, which can improve the suction of the entire suction device, improve the suction efficiency, and reduce the probability of channel blockage. Therefore, the first separation pipe 210 also needs to be set in two sets. The two sets of first separation pipes 210 are respectively connected to the two sets of suction channels 120, and the two sets of first separation pipes 210 are symmetrically arranged on both sides of the second separation pipe 220. The first outlet 211 of the two sets of first separation pipes 210 are both facing the positioning ring 221 of the second separation pipe 220, which can both realize the breaking of foam.

[0050] Furthermore, to facilitate the cleaning of the sludge storage box 130, a front cover 131 and a rear cover 132 are provided on the sludge storage box 130. Both the front cover 131 and the rear cover 132 are detachably mounted on the sludge storage box 130, and the front cover 131 and the rear cover 132 can be removed separately to expose the interior of the sludge storage box 130. In this embodiment, the sludge storage box 130 adopts a design with independently detachable front cover 131 and rear cover 132, which can directionally expose the maintenance and cleaning area, thereby improving the convenience of cleaning. Especially in narrow spaces, directional operation can avoid the problem of not being able to remove the sludge storage box 130 as a whole due to space limitations.

[0051] Furthermore, it also includes a housing assembly 400, which includes a housing 410 and a handle 420 fixed on the housing 410. The suction channel 120 and the suction generating assembly 300 are both installed inside the housing 410. The housing 410 provides protection for the suction channel 120 and the suction generating assembly 300. At the same time, the vacuum cleaner can be held by hand through the handle 420, that is, the vacuum cleaner is a handheld vacuum cleaner, which is convenient for lifting the vacuum cleaner.

[0052] Furthermore, the suction generating assembly 300 includes a motor 310 and an impeller 320. The motor 310 is fixed inside the housing 410, and the impeller 320 is mounted on the output shaft of the motor 310. The suction generated by the impeller 320 can be transmitted to the sludge collection box 130 through the second separation pipe 220. The motor 310 is used to drive the impeller 320 to rotate, and the rotation of the impeller 320 drives the airflow. According to the tilt angle of the impeller 320, the air can be drawn from the second separation pipe 220 to provide suction. However, since electrical components such as the motor 310 are used, they are easily corroded by liquids. Therefore, it is necessary to reduce the amount of liquid and foam entering the suction generating assembly 300 in order to improve the service life of components such as the motor 310.

[0053] In this embodiment, a vacuuming device is disclosed, including a vacuuming execution component 100, a separation component 200, and a suction generating component 300. The vacuuming execution component 100 includes a vacuum head 110, a vacuuming channel 120, and a sludge collection box 130. The separation component 200 includes a first separation tube 210 and a second separation tube 220 arranged within the sludge collection box 130. The suction generating component 300 provides suction power that passes sequentially through the second separation tube 220, the sludge collection box 130, the first separation tube 210, and the vacuuming channel 120. The first end of the second separation tube 220 is provided with a positioning ring 221 and is connected to... The suction generating component 300 is connected to the first inlet 222 at its second end, which is connected to the sludge storage box 130. The first end of the first separation pipe 210 is connected to the dust collection channel 120, and the second end is connected to the first outlet 211, which is connected to the sludge storage box 130. The first outlet 211 is positioned opposite to the positioning ring 221 and is used to guide the gas to impact the positioning ring 221 to break the foam in the gas. Through a specific structural design, the foam in the intake airflow is effectively broken, which greatly reduces the amount of foam entering the suction generating component 300 and improves the service life of the suction generating component 300.
