Cleaning head and vacuum cleaner

Abstract

The present invention relates to a cleaning head and a vacuum cleaner. The cleaning head comprises: a housing, a housing having a housing formed therein, a cleaning suction port communicating with the housing chamber at one end of the housing, and an outlet communicating with the housing chamber at the other end of the housing; a fan blade rotatably disposed within the housing chamber; and a first cleaning member disposed on the fan blade. The fan blade is capable of rotating under the action of airflow flowing from the cleaning suction port to the outlet. When the vacuum cleaner is performing vacuuming, a negative pressure device generates negative pressure to drive external air from the cleaning suction port through the housing chamber. The fan blade within the housing chamber rotates under the action of the airflow, simultaneously driving the first cleaning member on the fan blade to rotate. The rotating first cleaning member then cleans the surface to be cleaned outside the cleaning suction port, thereby achieving automatic cleaning of the cleaning head and saving manpower. Furthermore, since a power device is not required to be installed in the cleaning head, the overall weight of the cleaning head is relatively light and noiseless. The cleaning head can achieve both automatic cleaning and low weight and noise.

Description

Technical Field

[0001] The present invention relates to the technical field of dust collection, in particular to a cleaning head and a dust collector. Background Art

[0002] Vacuum cleaners are increasingly popular in households due to their ease of use and effective cleaning performance. The vacuum cleaner's motor drives the blades to rotate at high speed, creating negative pressure within the sealed housing. This pressure differential draws in dust-laden air. Vacuum cleaners often require various cleaning heads for additional cleaning assistance.

[0003] The cleaning head is used to pick up dust and debris on the cleaning surface and throw the dust into the air so that it can be sucked into the vacuum cleaner, or the cleaning head is used to throw out debris in narrow gaps for easy cleaning. Common cleaning heads include simple types, such as brushes, flat suction brushes and soft feather brushes, but simple cleaning heads do not have a power device, requiring the user to manually operate the cleaning head, which makes the cleaning process laborious. Common cleaning heads also have a more complex type. This type of cleaning head has its own power device, but it is usually heavy, noisy and expensive. Therefore, traditional cleaning heads cannot take into account both automatic cleaning and low weight and noise. Summary of the Invention

[0018] In one embodiment, the first cleaning member is disposed on the fan blade and faces the cleaning suction port, and the first cleaning member is not lower than the plane where the cleaning suction port is located.

[0019] In one embodiment, the fan blade includes a mounting seat, a blade and a brush holder, the blade and the brush holder are arranged around the periphery of the mounting seat and fixedly connected to the mounting seat, and the first cleaning member is arranged on the brush holder and faces the cleaning suction port.

[0020] In one embodiment, a slot is formed on a side of the brush holder facing the cleaning suction port, and the first cleaning member is inserted into the slot.

[0021] In one embodiment, the blades include a plurality of blades, the brush holders include a plurality of brush holders, and the plurality of blades and the plurality of brush holders are staggered along the outer circumference of the mounting base.

[0022] In one embodiment, the device further comprises a bracket, wherein the bracket is arranged on the inner wall of the accommodating cavity, and the fan blade is rotatably arranged on the bracket;

[0023] A through hole is formed between the bracket and the inner wall of the accommodating cavity, and the through hole allows air flow from the cleaning suction port to pass through the fan blade and then flow to the outlet.

[0035] Figure 1 This is a schematic structural diagram of a vacuum cleaner according to an embodiment of the present invention; Figure 2 for Figure 1 Exploded view of the cleaning head in the vacuum cleaner shown.

[0036] See Figure 1-Figure 2 In one embodiment of the present invention, a cleaning head 100 is provided. The cleaning head 100 is assembled at the end of the dust suction tube 230 of the vacuum cleaner 200, and is used to contact the surface to be cleaned, such as the ground, to pick up dust on the surface to be cleaned, so that the vacuum cleaner 200 can suck in the dust.

[0037] Specifically, when the vacuum cleaner 200 is working, the cleaning head 100 is installed on the dust suction pipe 230, the outlet 114 of the cleaning head 100 is connected to the inside of the dust suction pipe 230, and the main unit 210 is arranged at the end of the dust suction pipe 230 away from the cleaning head 100. The main unit 210 is equipped with a negative pressure device. The negative pressure device sucks the external airflow into the dust suction pipe 230 through the cleaning head 100. Finally, the negative pressure device separates the inhaled air from the air and dust, collects the separated dust in the dust box, and discharges the clean air to the outside, thus completing the vacuuming work.

[0038] In some embodiments, the cleaning head 100 includes a shell 10, a fan blade 30 and a first cleaning component 50. A accommodating chamber 11 is formed inside the shell 10. A cleaning suction port 112 connected to the accommodating chamber 11 is opened at one end of the shell 10, and an outlet 114 connected to the accommodating chamber 11 is opened at the other end of the shell 10. The fan blade 30 is rotatably arranged in the accommodating chamber 11; wherein, the fan blade 30 can rotate under the action of the airflow flowing from the cleaning suction port 112 to the outlet 114.

[0039] In this way, the fan blade 30 is set in the shell of the cleaning head 100. When the vacuum cleaner 200 performs vacuuming, the negative pressure device generates negative pressure to drive the outside air to flow through the cleaning suction port 112 through the accommodating chamber 11. The fan blade 30 in the accommodating chamber 11 will rotate under the action of the airflow, and at the same time drive the first cleaning member 50 on the fan blade 30 to rotate, and then the surface to be cleaned outside the cleaning suction port 112 is cleaned by the rotating first cleaning member 50. In this way, the first cleaning member 50 can automatically rotate to perform the cleaning work, thereby realizing automatic cleaning of the cleaning head 100 and saving manpower. At the same time, there is no need to assemble a power device in the cleaning head 100. The overall weight of the cleaning head 100 is relatively light, no noise is generated, and the cost is also relatively low. The cleaning head 100 can take into account the effects of automatic cleaning and low weight and noise.

[0040] Optionally, the fan blades 30 are rotatably disposed within the accommodating chamber 11 about a first direction, and the first direction intersects the plane in which the cleaning suction port 112 is located. Thus, when airflow flows from the cleaning suction port 112 to the outlet 114, the fan blades are driven to rotate about the direction of the airflow. The fan blades 30 are subjected to a greater force from the airflow, efficiently converting the flow of the airflow into rotation of the fan blades 30. Specifically, in this embodiment, the fan blades 30 are axial flow fan blades, and the first direction is perpendicular to the plane in which the cleaning suction port 112 is located. It is understood that in other embodiments, the fan blades 30 may also be other types of fan blades, such as cross-flow fan blades, which are not limited here.

[0041] Furthermore, the first cleaning member 50 is arranged on the fan blade 30 and faces the cleaning suction port 112, and the first cleaning member 50 is not lower than the plane where the cleaning suction port 112 is located, so that when the first cleaning member 50 rotates, it can contact the surface to be cleaned outside the cleaning suction port 112, and the surface to be cleaned can be cleaned by the first cleaning member 50.

[0042] Furthermore, the fan blade 30 includes a mounting base 32, blades 34, and a brush holder 36. The blades 34 and brush holder 36 are arranged around the periphery of the mounting base 32 and are fixedly connected to the mounting base 32. The first cleaning member 50 is disposed on the brush holder 36 and faces the cleaning suction port 112. Thus, the fan blade 30 includes blades 34, which interact with the airflow flowing into the accommodating chamber 11, driving the mounting base 32 to rotate, thereby driving the brush holder 36 disposed on the mounting base 32 to rotate. Finally, the first cleaning member 50 disposed on the brush holder 36 also rotates with the brush holder 36. In this way, the wind force generated by the flow of air drives the first cleaning member 50 to automatically rotate, achieving the automatic cleaning effect of the cleaning head 100. Specifically, a slot 37 is defined on the side of the brush holder 36 facing the cleaning suction port 112. The first cleaning member 50 is removably inserted into the slot 37, and the first cleaning member 50 can be easily assembled to the brush holder 36.

[0043] Specifically in this embodiment, the blades 34 include multiple blades, and the brush holders 36 include multiple brush holders. The multiple blades 34 and the multiple brush holders 36 are staggered around the outer peripheral surface of the mounting base 32, that is, a brush holder 36 is provided between two adjacent blades 34, and a blade 34 is provided between two adjacent brush holders 36. The blades 34 and the brush holders 36 are staggered, and the multiple blades 34 can be evenly affected by the airflow. At the same time, the multiple brush holders 36 are evenly spaced, and can evenly clean the surface to be cleaned.

[0044] In some embodiments, the cleaning head 100 also includes a bracket 60, which is arranged on the inner wall of the accommodating chamber 11, and the fan 30 is rotatably arranged on the bracket 60; wherein, a through hole is formed between the bracket 60 and the inner wall of the accommodating chamber 11, and the through hole allows the airflow to flow from the cleaning suction port 112 through the fan blade to the outlet 114. In this way, the fan blade 30 is supported by the bracket 60 so that the fan blade 30 can be rotatably assembled in the accommodating chamber 11. At the same time, a through hole is formed between the bracket 60 and the accommodating chamber 11, which allows the airflow to pass through the fan blade 30 and the bracket 60 and then flow out from the outlet 114 without affecting the normal flow of the airflow.

[0045] Specifically, the bracket 60 includes a support seat 62 and a plurality of support rods 64, one end of the plurality of support rods 64 is arranged at intervals around the outer circumference of the support seat 62, and the other end of the plurality of support rods 64 away from the support seat 62 is fixedly connected to the inner wall of the accommodating chamber 11. In this way, the bracket 60 is formed by arranging a plurality of support rods 64 at intervals on the support seat 62 to fix the bracket 60 in the accommodating chamber 11, and a through hole can be formed between the bracket 60 and the inner wall of the accommodating chamber 11. Optionally, the fan blade 30 is rotatably arranged on the support seat 62. Also optionally, the cleaning head 100 further includes a bearing 65, a mounting hole is provided on the support seat 62, the bearing 65 is sleeved in the mounting hole, and the mounting seat 32 of the fan blade 30 is sleeved in the inner ring of the bearing 65, so that the fan blade 30 can rotate flexibly around the support seat 62.

[0046] In some embodiments, the cleaning head 100 further includes a second cleaning member 70. The housing 10 has a bottom surface with a cleaning suction port 112, and the second cleaning member 70 is disposed on the bottom surface around the cleaning suction port 112. Thus, by disposing the second cleaning member 70 around the cleaning suction port 112, the cleaning head 100 can not only clean dust with the automatically rotating first cleaning member 50, but also clean with the second cleaning member 70 around the cleaning suction port 112, thereby improving the cleaning effect by utilizing multiple cleaning members.

[0047] Specifically, the first cleaning member 50 is a first brush body, and the second cleaning member 70 is a second brush body. The first brush body can automatically rotate with the fan blade 30 to pick up dust. The second brush body is arranged around the cleaning suction port 112 and can further pick up dust near the cleaning suction port 112, further improving the cleaning effect. It is understandable that in other embodiments, the first cleaning member 50 and the second cleaning member 70 can also be other cleaning members such as rags, which is not limited here.

[0048] Furthermore, the height of the first brush body relative to the plane where the cleaning suction port 112 is located is greater than the height of the second brush body relative to the plane where the cleaning suction port 112 is located. In other words, relative to the plane where the cleaning suction port 112 is located, the first brush body is arranged to protrude from the second brush body, so that during the cleaning process, the first brush body can first contact the ground surface to be cleaned, and cleaning can be mainly performed by the automatically rotating first brush body. Moreover, in order to improve the cleaning effect during the cleaning process, when the first brush body is pressed against the surface to be cleaned, the first brush body can bend and deform, and then the first brush body and the second brush body can clean simultaneously. The first brush body abuts against the surface to be cleaned with greater pressure and automatically rotates relative to the surface to be cleaned, while the second brush body also contacts the surface to be cleaned, resulting in a better cleaning effect.

[0049] Optionally, the hardness of the first brush body is less than that of the second brush body. This allows the relatively protruding first brush body to deform and bend more easily when squeezed by an external force, allowing the second brush body to contact the surface to be cleaned. The first brush body, which rotates relative to the housing 10, and the second brush body, which is fixed relative to the housing, can cooperate to clean, thereby improving the cleaning effect. Furthermore, the relatively soft first brush body has less deformation force after contraction, and less friction with the surface to be cleaned, allowing it to rotate automatically driven by the fan blades 30. Furthermore, the second brush body has a greater hardness than the first brush body, resulting in a better cleaning effect. By combining brush bodies with different cleaning effects, cleaning performance is comprehensively improved.

[0050] Optionally, the first brush body is a soft brush, and the second brush body is a felt.

[0051] In some embodiments, the housing 10 has a bottom surface with a cleaning suction port 12 and an outer side surface 12 intersecting and connected with the bottom surface. When the cleaning head 100 cleans the floor, the outer side surface 12 of the housing 10 may contact a wall or other component. The outer side surface 12 includes a circular arc surface 121, a first corner surface, and a second corner surface. The first corner surface and the second corner surface intersect and connect, and the circular arc surface 121 is connected between the two ends of the first corner surface and the second corner surface that are away from each other. The first corner surface and the second corner surface are arranged to intersect so that the outer side surface 12 of the housing 10 has an edge at a right angle or other angle, which facilitates the cleaning head 100 to enter the corner for cleaning. At the same time, the circular arc surface 121 is provided between the two opposite ends of the first corner surface and the second corner surface, so that the circular arc surface 121 can be matched with the fan blade 30, so that the housing is at least partially set to an arc shape, which is convenient for assembling the fan blade 30 that needs to perform rotational motion.

[0052] Figure 1 This is a schematic structural diagram of a vacuum cleaner according to an embodiment of the present invention; Figure 2 for Figure 1 Exploded view of the cleaning head in the vacuum cleaner shown.

[0053] See Figure 1-Figure 2 Based on the same inventive concept, an embodiment of the present invention further provides a vacuum cleaner 200, wherein the cleaning head 100 includes a shell 10, a fan blade 30 and a first cleaning member 50. An accommodating chamber 11 is formed inside the shell 10, a cleaning suction port 112 communicating with the accommodating chamber 11 is formed at one end of the shell 10, and an outlet 114 communicating with the accommodating chamber 11 is formed at the other end of the shell 10. The fan blade 30 is rotatably disposed in the accommodating chamber 11; wherein the fan blade 30 can rotate under the action of the airflow flowing from the cleaning suction port 112 to the outlet 114.

[0054] In this way, the fan blade 30 is set in the shell of the cleaning head 100. When the vacuum cleaner 200 performs vacuuming, the negative pressure device generates negative pressure to drive the outside air to flow through the cleaning suction port 112 through the accommodating chamber 11. The fan blade 30 in the accommodating chamber 11 will rotate under the action of the airflow, and at the same time drive the first cleaning member 50 on the fan blade 30 to rotate, and then the surface to be cleaned outside the cleaning suction port 112 is cleaned by the rotating first cleaning member 50. In this way, the first cleaning member 50 can automatically rotate to perform the cleaning work, thereby realizing automatic cleaning of the cleaning head 100 and saving manpower. At the same time, there is no need to assemble a power device in the cleaning head 100. The overall weight of the cleaning head 100 is relatively light, no noise is generated, and the cost is also relatively low. The cleaning head 100 can take into account the effects of automatic cleaning and low weight and noise.

[0055] Specifically, when the vacuum cleaner 200 is working, the cleaning head 100 is installed on the dust suction pipe 230, the outlet 114 of the cleaning head 100 is connected to the inside of the dust suction pipe 230, and the main unit 210 is arranged at the end of the dust suction pipe 230 away from the cleaning head 100. The main unit 210 is equipped with a negative pressure device. The negative pressure device sucks the external airflow into the dust suction pipe 230 through the cleaning head 100. Finally, the negative pressure device separates the inhaled air from the air and dust, collects the separated dust in the dust box, and discharges the clean air to the outside, thus completing the vacuuming work.

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
