Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a dust collection mechanism and a cleaning host. Background Technology

[0002] Dust collection mechanisms can separate and collect dirt in the air. Most existing dust collection mechanisms form a rotating airflow by rotating the gas entering the dust cup around the separation component, which allows heavier dirt such as hair and debris to gradually settle at the bottom of the dust cup, thus achieving air-to-dirt separation.

[0003] However, the contaminants carried in the gas also include some tiny dust particles. Because these tiny dust particles are relatively small, they are difficult to reach the bottom of the dust cup by their own weight, thus affecting the overall separation effect of the equipment.

[0004] Therefore, there is an urgent need to provide a dust collection mechanism and a cleaning host to solve the problems existing in the prior art to a certain extent. Summary of the Invention

[0005] The purpose of this invention is to provide a dust collection mechanism and a cleaning host, so as to optimize the structure of the dust collection mechanism to a certain extent and improve the disassembly and assembly efficiency and stability of the dust collection mechanism.

[0006] The present invention provides a dust collection mechanism, including a separation component, a dust cup, and a guide member; the separation component is disposed inside the dust cup, and the separation component is spaced apart from the inner wall of the dust cup to form an air guide channel surrounding the separation component; an air inlet is formed on the dust cup, and the air inlet is connected to the air guide channel, through which air enters the dust cup and flows along the air guide channel; the guide member is connected to the separation component, and the guide member has an air guide surface, which is arranged facing the air flow direction to guide the air towards the bottom of the dust cup.

[0007] The separation component has a guide slope formed at the position of the air inlet, and the first side of the guide slope abuts against the first side of the air inlet.

[0008] Specifically, the first contact surface of the guide member is in contact with the first side of the air guide slope, and the thickness of the guide member is not less than the gap between the inner wall of the dust cup and the separation component.

[0009] Specifically, the separating assembly comprises an air outlet member, a first separating member and a second separating member; the air outlet member is arranged at one end of the first separating member, and the second separating member is arranged at the other end of the first separating member away from the air outlet member; a guide air slope is formed on the first separating member; the diameter of the first separating member is smaller than that of the air outlet member, so that a stepped surface is formed at the joint end of the first separating member and the air outlet member, and the second fitting surface of the guide member is fitted with the stepped surface.

[0010] Further, the size a of the first fitting surface is between 25mm and 40mm, and the size b of the second fitting surface is between 0.9a and 1.4a.

[0011] Further, the first separating member comprises a first air guide section and a filtering section; one end of the first air guide section is connected with the air outlet member, and the other end is connected with the filtering section; a plurality of filtering holes are distributed on the filtering section, so as to allow air to enter the filtering section and block dirt in the air outside the filtering section.

[0012] Further, the guide air surface comprises a first transition section, a straight section and a second transition section; the first transition section is arc-shaped, and the end of the first transition section is tangent to the connection position of the first air guide section and the filtering section; the second transition section is arc-shaped, and the end of the second transition section is tangent to the stepped surface; the included angle between the straight section and the axis direction of the first separating member is between 25° and 50°.

[0013] Further, the second separating member comprises a dust cover and a second air guide section; one end of the second air guide section is connected with the other end of the first separating member away from the air outlet member, and the dust cover is arranged at the connection position of the first separating member and the second air guide section; the other end of the second air guide section is fitted with the bottom wall of the dust cup; the air outlet member comprises a mounting cover and a filtering piece; the mounting cover is connected with the other end of the first separating member away from the second separating member, the mounting cover forms an air outlet, and the filtering piece is encapsulated in the air outlet.

[0014] Specifically, the outer wall surface of the mounting cover is formed with a plurality of clamping protrusions, and the plurality of clamping protrusions are arranged at intervals along the circumference of the mounting cover; the inner wall surface of the dust cup is formed with a screw guide groove corresponding to the position of the clamping protrusion, the clamping protrusion can be inserted into the screw guide groove and moved along the extension direction of the screw guide groove, so that the dust cup and the mounting cover are rotationally connected.

[0015] Compared with the prior art, the dust collecting mechanism provided by the present application has the following advantages:

[0016] The dust collecting mechanism provided by the application comprises a separation assembly, a dust cup and a guide piece. The separation assembly is arranged in the interior of the dust cup, and the separation assembly is arranged in a spaced manner with the inner wall of the dust cup to form an air guide flow channel around the separation assembly. An air inlet is formed on the dust cup, and the air inlet is in communication with the air guide flow channel. Air enters the dust cup through the air inlet and flows along the air guide flow channel. The guide piece is connected with the separation assembly, and the guide piece forms an air guide surface which is arranged towards the air flow direction to generate a guiding effect on the air towards the bottom of the dust cup.

[0017] According to the analysis, the air with dirt sucked in can enter the dust cup through the air inlet formed on the dust cup. Since the separation assembly is arranged in the dust cup and is arranged in a spaced manner with the dust cup to form an air guide flow channel around the separation assembly, the air entering the dust cup can rotate around the separation assembly. During the rotation, the dirt such as dust, debris and hair in the air can be separated from the air through the separation assembly and gradually deposited at the bottom of the dust cup under the influence of gravity.

[0018] However, since there are some dust and particles with light weight or small size in the dirt, such dust or particles are difficult to fall downwards and deposit at the bottom of the dust cup along with the air. Therefore, the guide piece is arranged between the dust cup and the separation assembly, and the guide piece has an air guide surface which is arranged towards the air flow direction and can generate a guiding effect on the air towards the bottom of the dust cup. Therefore, when the dirt such as light dust and particles contacts the air guide surface, the dirt moves towards the bottom of the dust cup under the action of the air guide surface, so that the separation of the light dust and particles can be realized, and the filtering effect is improved.

[0019] In addition, the application also provides a cleaning host comprising the dust collecting mechanism and the host. The dust collecting mechanism is detachably connected with the host. An air inlet channel is formed on the host, and the outlet end of the air inlet channel is in communication with the air inlet.

[0020] The cleaning host adopting the dust collecting mechanism provided by the application can not only realize the filtering and separation of the dirt with large weight and shape, but also has a good filtering effect on the small dust and particles, so that the cleaning degree of the discharged air is improved, and the dirt cleaning capacity and dust collecting capacity of the overall cleaning equipment are improved.

[0037] like Figures 1-3 As shown, the present invention provides a dust collection mechanism, including a separation component 2, a dust cup 1, and a guide member 3; the separation component 2 is disposed inside the dust cup 1, and the separation component 2 is spaced apart from the inner wall of the dust cup 1 to form an air guide channel surrounding the separation component 2; an air inlet 101 is formed on the dust cup 1, and the air inlet 101 is connected to the air guide channel, and air enters the dust cup 1 through the air inlet 101 and flows along the air guide channel; the guide member 3 is connected to the separation component 2, and the air guiding surface 303 of the guide member 3 is arranged facing the air flow direction to guide the air.

[0038] Compared with existing technologies, the dust collection mechanism provided by this invention has the following advantages:

[0039] The dust collection mechanism provided by this invention allows dirty air to enter the dust cup 1 through an air inlet 101. Since the separation component 2 is disposed inside the dust cup 1, and the separation component 2 and the dust cup 1 are spaced apart to form an airflow channel around the separation component 2, the air entering the dust cup 1 can rotate around the separation component 2. During this rotation, dirt in the air, such as dust, debris, and hair, can be separated from the air by the separation component 2 and gradually deposited at the bottom of the dust cup 1 under the influence of gravity.

[0040] However, since the dirt contains some light or small dust and particles, these dust or particles will rotate with the air and are difficult to fall down and settle at the bottom of the dust cup 1. Therefore, this application provides a guide 3 between the dust cup 1 and the separation component 2. The guide 3 has an airflow surface 303 that faces the airflow direction and can guide the air towards the bottom of the dust cup 1. Therefore, when light dust and particles come into contact with the airflow surface 303, they will move towards the bottom of the dust cup 1 under the action of the airflow surface 303, thereby achieving the separation of light or small dust and particles and improving the filtration effect.

[0041] It can be understood that, as Figure 1 shown, the dust cup 1 in the application is made of transparent material, so that the accumulation of dust in the dust cup 1 can be clearly observed, and the user can clean the internal dust and sundries in time to avoid the influence of too much dust on the separation effect.

[0042] In order to ensure that the air in the dust cup 1 can contact the air guide surface 303 of the guide piece 3 when rotating around the separation assembly 2, as Figures 1-3 shown, a guide inclined surface 2022 is formed at the position corresponding to the air inlet 101 of the separation assembly 2, and the first edge 2023 of the guide inclined surface 2022 abuts against the first edge of the air inlet 101.

[0043] The guide inclined surface 2022 formed at the position corresponding to the air inlet 101 of the separation assembly 2 and the first edge 2023 of the guide inclined surface 2022 abutting against the first edge of the air inlet 101 can have a certain degree of sealing effect, and the position is collectively referred to as a sealing edge below, so that the air entering through the air inlet 101 has only one flow direction through the sealing edge, which can avoid the formation of air turbulence in the dust cup 1 to affect the separation effect of gas and dust, and on the other hand, it can ensure that the air flow contacts the air guide surface 303 to a certain extent, realizing the guiding effect of the small dust in the gas.

[0044] Preferably, as Figures 1-3 shown, the first fitting surface 301 of the guide piece 3 is fitted with the first edge 2023 of the guide inclined surface 2022, and the thickness of the guide piece 3 is not less than the interval between the inner wall of the dust cup 1 and the separation assembly 2.

[0045] Firstly, the first fitting surface 301 of the guide piece 3 is tightly fitted with the first edge 2023 of the guide inclined surface 2022, that is, the first fitting surface 301 is tightly fitted with the sealing edge between the guide inclined surface 2022 and the air inlet 101, so that the air flow reaching the air guide surface 303 of the air guide piece is all guided downward by the air guide surface 303, thereby ensuring the uniqueness of the air flow to a certain extent.

[0046] Secondly, since the gas reaching the air guide surface 303 is mixed with dust and other dirt, and the dust cup 1 and the separation assembly 2 are detachably connected, the thickness of the guide piece 3 is not less than the interval between the inner wall of the dust cup 1 and the separation assembly 2, that is, after the dust cup 1 and the separation assembly 2 are connected, the side of the guide piece 3 facing the dust cup 1 can abut against the inner wall of the dust cup 1, thereby avoiding the problem of dust accumulation between the guide piece 3 and the dust cup 1 during use to a certain extent.

[0047] And, by making the one side of the guide piece 3 abutting against the inner wall of the dust cup 1, not only the dust can be blocked, but also the airflow can be blocked, so that the gas can only move downward along the air guide surface 303.

[0048] Here, it needs to be added that the distance between the dust cup 1 and the separation assembly 2 is usually between 10mm-20mm, so the thickness of the guide piece 3 in the present application is set according to the distance between the dust cup 1 and the separation assembly 2. And, the guide piece 3 in the present application is made of soft material, such as rubber, so the thickness of the guide piece 3 can be slightly larger than the distance between the dust cup 1 and the separation assembly 2, for example, if the distance between the dust cup 1 and the separation assembly 2 is 10mm, the thickness of the guide piece 3 can be 10mm-13mm, on the one hand, so that the dust cup 1 and the separation assembly 2 can press the guide piece 3 after installation, so that the abutment between the guide piece 3 and the dust cup 1 is more closely, on the other hand, it also will not affect the installation between the dust cup 1 and the separation assembly 2.

[0049] It can be understood that, as shown in Figures 1-3 The separation assembly 2 in the present application includes an air outlet member 201, a first separation member 202 and a second separation member 203; the air outlet member 201 is arranged at one end of the first separation member 202, and the second separation member 203 is located at the end of the first separation member 202 away from the air outlet member 201; an air guide inclined surface 2022 is formed on the first separation member 202; the diameter of the first separation member 202 is smaller than the diameter of the air outlet member 201, so that the abutting end of the first separation member 202 and the air outlet member 201 forms a stepped surface 2014, and the second abutting surface 302 of the guide piece 3 abuts with the stepped surface 2014.

[0050] By making the diameter of the first separation member 202 smaller than the diameter of the air outlet member 201, and the diameter of the second separation member 203 smaller than the diameter of the first separation member 202, the overall separation assembly 2 can form an inverted conical structure, so that the gas in the dust cup 1 can form a downward moving cyclone airflow around the separation assembly 2, and then the dust, debris and hair carried in the gas can gradually move to the bottom of the dust cup 1 under the influence of gravity.

[0051] Correspondingly, since the diameter of the air outlet member 201 is larger than the diameter of the first separation member 202, a stepped surface 2014 can be formed at the connection, so as to provide a stable installation position for the second abutting surface 302 of the guide piece 3. And, by making the second abutting surface 302 abut with the stepped surface 2014, the penetration of fine dust can also be avoided, and the setting of the guide piece 3 is more stable.

[0052] It can be understood that, as shown in Figure 2As shown, the size of the first bonding surface 301 in the present application is set according to the sealing edge as described above, and in actual application, the size of the sealing edge is usually between 25mm-40mm, thus the size of the first bonding surface 301 in the present application is consistent with the size of the sealing edge, which is between 25mm-40mm, and in order to ensure the formation of the air guide surface 303, the size of the second bonding surface 302 in the present application is between 0.9a-1.4a, i.e. the size of the second bonding surface 302 is between 0.9 times and 1.4 times of the size of the first bonding surface 301, so as to ensure the smooth formation of the air guide surface 303.

[0053] Optionally, as Figure 1 In combination Figure 5 As shown, the first separating member 202 in the present application comprises a first air guide section 2021 and a filtering section 2024, one end of the first air guide section 2021 is connected with the air outlet member 201, and the other end is connected with the filtering section 2024; the filtering section 2024 is distributed with a plurality of filtering holes, for allowing air to enter the filtering section 2024, and blocking the dirt in the air outside the filtering section 2024.

[0054] The air guide slope 2022 in the present application is formed on the first air guide section 2021 along the circumference of the first air guide section 2021, and the first air guide section 2021 only has the air guide function, and the gas entering the dust cup 1 from the air inlet 101 first contacts the air guide slope 2022, and flows around the first air guide section 2021 under the action of the air guide slope 2022, and finally contacts the air guide surface 303.

[0055] Under the action of the air guide surface 303, the gas flows to the filtering section 2024, and since the filtering section 2024 is distributed with a plurality of filtering holes, thus part of the dirt such as large particles, dust and hair in the gas at this position is affected by gravity and continues to move downward, and the other part is blocked by the filtering section 2024.

[0056] As Figure 5 As shown, since the first air guide section 2021 and the filtering section 2024 in the present application are both hollow cylindrical structures, thus the air after the separation of the gas and dirt can enter the filtering section 2024.

[0057] It should be noted here that since the filtering section 2024 cannot completely filter the fine dust or particles in the air, thus, as Figure 5As shown, the inside of the first air guide section 2021 and the filtering section 2024 in the application is also provided with a plurality of secondary cyclone cones 2025, and the plurality of secondary cyclone cones 2025 are all in a hollow conical structure, and the secondary cyclone cones 2025 are formed with air inlets, so that the air entering the filtering section 2024 can further enter the secondary cyclone cones 2025, and since the secondary cyclone cones 2025 are in a conical structure, the gas entering the secondary cyclone cones 2025 can still maintain a cyclone state, so as to further filter the fine dust carried in the gas.

[0058] The second air guide section 2032 in the application is also a hollow cylindrical structure, so that the secondary cyclone cones 2025 are communicated with the second air guide section 2032, so that the fine dust separated by the secondary cyclone cones 2025 falls into the second air guide section 2032. After the dust cup 1 is separated from the separation assembly 2, the fine dust in the second air guide section 2032 falls into the dust cup 1, that is, the second air guide section 2032 can cooperate with the dust cup 1 to form a first dust storage chamber 2033, and the second air guide section 2032 forms a second dust storage chamber 2034, the first dust storage chamber 2033 is used for carrying dust, debris and hair and other dirt with relatively large weight, and the second dust storage chamber 2034 is used for carrying fine dust and debris filtered by the secondary cyclone cones, when the dust cup 1 is separated from the separation assembly 2, the fine dust and debris can fall out of the second dust storage chamber 2034 and enter the dust cup 1, so as to improve the separation effect of the overall structure.

[0059] In order to ensure that the air guide surface 303 can better guide the airflow and dust, the air guide surface 303 is provided with a plurality of air guide grooves 3034, and the air guide grooves 3034 are arranged in the air guide surface 303 in a staggered manner. Figure 2 As shown, the air guide surface 303 in the application includes a first transition section 3031, a straight section 3032 and a second transition section 3033; the first transition section 3031 is arc-shaped, and the end of the first transition section 3031 is tangent to the connection position of the first air guide section 2021 and the filtering section 2024; the second transition section 3033 is arc-shaped, and the end of the second transition section 3033 is tangent to the stepped surface 2014; the angle between the straight section 3032 and the axis direction of the first separation member 202 is between 25°-50°.

[0060] Since the first fitting surface 301 of the guide piece 3 in the application is fitted with the sealing edge, and the size of the first fitting surface 301 of the guide piece 3 is the same as the size of the sealing edge, the end of the first transition section 3031 of the above-mentioned application is tangent to the connection position of the first air guide section 2021 and the filtering section 2024, which can be understood as that the end of the first transition section 3031 can be tangent to the plane where the connection position of the first air guide section 2021 and the filtering section 2024 is located, so that the airflow passing through the air guide surface 303 can directly enter the filtering section 2024 from the first air guide section 2021.

[0061] By tangency of the second transition section 3033 and the stepped surface 2014, the airflow close to the air outlet member 201 can smoothly contact the air guide surface 303 and move downward under the action of the air guide surface 303. Moreover, since the second transition section 3033 is arc-shaped, the air resistance to the airflow can be reduced, thereby ensuring the airflow intensity and reducing the noise to a certain extent.

[0062] By setting the included angle between the straight section 3032 between the first transition section 3031 and the second transition section 3033 and the first separation member 202 to be between 25° and 50°, a smooth guide surface can be formed between the first transition section 3031 and the second transition section 3033, thereby ensuring the air guide effect.

[0063] Optionally, as shown in Figures 1-3 the second separation member 203 includes a dust cover 2031 and a second air guide section 2032, one end of the second air guide section 2032 is connected to the end of the first separation member 202 away from the air outlet member 201, and the dust cover 2031 is arranged at the connection position of the first separation member 202 and the second air guide section 2032; the other end of the second air guide section 2032 is attached to the bottom wall of the dust cup 1; the air outlet member 201 includes a mounting cover 2011 and a filter 2012, the mounting cover 2011 is connected to the end of the first separation member 202 away from the second separation member 203, the mounting cover 2011 is formed with an air outlet, and the filter 2012 is encapsulated at the air outlet.

[0064] By the dust cover 2031 surrounding the second air guide section 2032, the dust, debris and hair falling into the bottom of the dust cup 1 can be prevented from being affected by the airflow and flying up again to a certain extent, thereby ensuring the overall filtering effect.

[0065] By the mounting cover 2011 arranged at one end of the first separation member 202 and the filter 2012 encapsulated at the air outlet of the mounting cover 2011, the air separated by the secondary cyclone cone 2025 can be discharged from the air outlet and filtered again by the filter 2012 during the discharging process, thereby further reducing the fine dust carried in the discharged air and improving the quality of the discharged air.

[0066] Preferably, as shown in Figure 3 in combination with Figure 4 the outer wall surface of the mounting cover 2011 is formed with a plurality of clamping protrusions 2013, the plurality of clamping protrusions 2013 are arranged at intervals along the circumference of the mounting cover 2011; the inner wall surface of the dust cup 1 is formed with a screw guide groove 102 corresponding to the position of the clamping protrusion 2013, the clamping protrusion 2013 can be inserted into the screw guide groove 102 and moved along the extension direction of the screw guide groove 102, so that the dust cup 1 and the mounting cover 2011 are rotationally connected.

[0067] When the dust cup 1 needs to be connected with the mounting cover 2011, first, the clamping protrusion 2013 is aligned with the screw guide groove 102, the clamping protrusion 2013 is inserted into the screw guide groove 102, and then the dust cup 1 is rotated, so that the clamping protrusion 2013 is clamped into the screw guide groove 102, and the connection of the dust cup 1 and the mounting cover 2011 is realized.

[0068] In addition, the application further provides a cleaning main machine, comprising the dust collecting mechanism and the main machine; the dust collecting mechanism is detachably connected with the main machine; the main machine is formed with an air inlet channel, and the outlet end of the air inlet channel is communicated with the air inlet 101.
