Description

Technical Field

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

[0002] With the improvement of living standards and the continuous development of technology, people's demand for handheld vacuum cleaners and vacuum-mop combos has gone beyond just meeting daily cleaning needs. They also require the equipment to be lightweight, labor-saving, and comfortable to use.

[0003] However, due to the unreasonable weight distribution of traditional vacuum cleaners or vacuum-mop combos, it is quite strenuous for users to use them by hand, and even cause arm soreness after prolonged use, which greatly reduces the user experience.

[0004] Therefore, there is an urgent need to provide a cleaning host to address the problems existing in the current technology to some extent. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning host that optimizes the structure of the cleaning host to a certain extent, making it easier for users to operate.

[0006] This invention provides a cleaning host, comprising a main body, a drive assembly, a dust collection mechanism, and a power supply mechanism. The dust collection mechanism is detachably connected to the main body. The drive assembly is disposed within the main body, and the dust collection mechanism is located at the front end of the drive assembly, with the axis of the drive assembly collinear with the axis of the dust collection mechanism. The main body forms a first channel and a gripping portion. The first channel is located below the dust collection mechanism, and one end of the first channel is connected to the dust collection mechanism. The drive assembly forms a second channel, one end of which is connected to the dust collection mechanism. The power supply mechanism is connected to the main body and located below the first channel. The gripping portion is located below the drive assembly and behind the power supply mechanism, and the gripping portion is spaced apart from the power supply mechanism to form a gripping space.

[0007] The grip portion includes a handle, a connecting section, and a transition section. One end of the connecting section is connected to one end of the handle, and the other end is connected to the main body mechanism. The other end of the handle is connected to the transition section. The handle is inclined, the connecting section is horizontal, and the angle between the axis of the handle and the axis of the connecting section is between 66° and 82°. The transition section is arc-shaped. The side of the handle facing the grip space forms a first transition arc surface with a radius between 11mm and 28mm between the transition section and the main body mechanism. The side of the handle away from the grip space forms a second transition arc surface with a radius between 3mm and 19mm between the transition section. The end of the handle also has a transition surface with an angle of 56.5° to 71.5° with the axis of the handle.

[0008] Specifically, the main body includes a main body and an air outlet filter assembly; the main body has a receiving portion, the drive assembly is disposed in the receiving portion, and the outer wall surface of the main body corresponding to the position of the receiving portion is provided with a speed adjustment button and a display screen; the air outlet filter assembly is connected to the main body and is located at the end of the drive assembly away from the dust collection mechanism; the air outlet filter assembly has an air outlet hole, and the end of the second channel away from the dust collection mechanism is connected to the air outlet hole.

[0009] Furthermore, the air outlet filter assembly includes a first housing and a first filter element; the number of air outlets is multiple, and the multiple air outlets are arranged in an array and formed on both sides of the first housing; the first filter element is disposed inside the first housing, and a first mating part is formed on the inner wall surface of the first housing, and a second mating part is formed on the main body corresponding to the position of the first housing, and the first mating part and the second mating part cooperate to make the first housing and the main body detachably connected.

[0010] Furthermore, a recess is formed on the end face of the first housing away from the main body, and a start button is provided at the lowest position of the recess. The connection end of the start button passes through the first housing and can abut against or separate from the start button of the drive assembly.

[0011] The main body has a mounting groove corresponding to the position of the power supply mechanism. One end of the power supply mechanism is inserted into the mounting groove, and the power supply mechanism is detachably connected to the mounting groove.

[0012] Specifically, the power supply mechanism includes a power source and a second housing. The power source is disposed within the second housing. A guide protrusion extending in the insertion direction is formed on the second housing. A guide groove is formed in the mounting groove corresponding to the position of the guide protrusion. A locking portion and a pressing portion are formed at the end of the guide protrusion. One end of the locking portion protrudes from the guide protrusion. A positioning portion is formed in the mounting groove corresponding to the position of the locking portion. The end of the locking portion protruding from the guide protrusion can be locked into the positioning portion. The pressing portion is connected to the other end of the locking portion, and pressing the pressing portion can cause the end of the locking portion protruding from the guide protrusion to retract.

[0013] Furthermore, a foolproof protrusion is formed on the second housing, the foolproof protrusion extends along the insertion direction, and the mounting groove has an alignment recess formed at the position corresponding to the foolproof protrusion.

[0014] Furthermore, a power transmission section is formed at one end of the second housing that is inserted into the mounting groove, and a conductive section is formed inside the mounting groove corresponding to the position of the power transmission section. The power transmission section contacts the conductive section to connect the power. An indicator light and a charging port are also formed on the second housing, and the charging port is located at the end of the second housing away from the power transmission section, and the indicator light is located on the side of the second housing.

[0015] Furthermore, the dust collection mechanism includes a dust cup and a filter assembly. The filter assembly is disposed inside the dust cup and is spaced apart from the inner wall of the dust cup to form an air guide channel. An air inlet is formed on the dust cup and is connected to the air outlet of the first channel. An air outlet is formed on the filter assembly and is connected to one end of the second channel.

[0016] Compared with existing technologies, the cleaning host provided by this invention has the following advantages:

[0017] The cleaning host provided by the present invention includes a main body, a drive assembly, a dust collection mechanism, and a power supply mechanism. The dust collection mechanism is detachably connected to the main body. The drive assembly is disposed within the main body, and the dust collection mechanism is located at the front end of the drive assembly, with the axis of the drive assembly and the axis of the dust collection mechanism being collinear. The main body forms a first channel and a gripping part. The first channel is located below the dust collection mechanism, and one end of the first channel is connected to the dust collection mechanism. The drive assembly forms a second channel, and one end of the second channel is connected to the dust collection mechanism. The power supply mechanism is connected to the main body and is located below the first channel. The gripping part is located below the drive assembly and behind the power supply mechanism, and the gripping part and the power supply mechanism are spaced apart to form a gripping space.

[0018] This analysis shows that, among the drive component, dust collection mechanism, and power supply mechanism, the drive component has the greatest weight. Therefore, by placing the drive component inside the main body and at the rear of the main body, and by placing the dust collection mechanism at the front of the drive component, the axis of the drive component and the axis of the dust collection mechanism are collinear, which can balance the weight of the drive component to a certain extent.

[0019] In this application, by placing the power supply mechanism connected to the main body below the dust collection mechanism, the weight of the drive components can be further balanced, making the center of gravity of the overall machine closer to the middle position. This makes the cleaning host provided by this application less strenuous to use and improves the user experience.

[0020] Furthermore, during use, the air containing dust, hair, and other dirt is filtered by the dust collection mechanism and then discharged through the second channel formed by the drive component. Since the axis of the drive component in this application is collinear with the axis of the dust collection mechanism, the center of the air outlet of the dust collection mechanism in this application is located on the axis of the second channel. This allows the filtered air to be discharged quickly, reducing wind resistance and increasing suction power, while also reducing noise to a certain extent, providing users with a better user experience.

[0039] like Figure 1 Combination Figure 2 As shown, the present invention provides a cleaning host, including a main body, a drive assembly 3, a dust collection mechanism 4, and a power supply mechanism 5; the dust collection mechanism 4 is detachably connected to the main body, the drive assembly 3 is disposed inside the main body, the dust collection mechanism 4 is located at the front end of the drive assembly 3, and the axis of the drive assembly 3 is collinear with the axis of the dust collection mechanism 4; the main body forms a first channel 101 and a gripping part, the first channel 101 is located below the dust collection mechanism 4, and one end of the first channel 101 is connected to the dust collection mechanism 4, the drive assembly 3 forms a second channel, and one end of the second channel is connected to the dust collection mechanism 4; the power supply mechanism 5 is connected to the main body and is located below the first channel 101; the gripping part is located below the drive assembly 3 and behind the power supply mechanism 5, and the gripping part and the power supply mechanism 5 are spaced apart to form a gripping space 106.

[0040] Compared with existing technologies, the cleaning host provided by this invention has the following advantages:

[0041] The cleaning host provided by the present invention includes a main body, a drive assembly 3, a dust collection mechanism 4, and a power supply mechanism 5. The dust collection mechanism 4 is detachably connected to the main body. The drive assembly 3 is disposed inside the main body, and the dust collection mechanism 4 is located at the front end of the drive assembly 3, with the axis of the drive assembly 3 and the axis of the dust collection mechanism 4 being collinear. The main body forms a first channel 101 and a gripping part. The first channel 101 is located below the dust collection mechanism 4, and one end of the first channel 101 is connected to the dust collection mechanism 4. The drive assembly 3 forms a second channel, and one end of the second channel is connected to the dust collection mechanism 4. The power supply mechanism 5 is connected to the main body and is located below the first channel 101. The gripping part is located below the drive assembly 3 and behind the power supply mechanism 5, and the gripping part and the power supply mechanism 5 are spaced apart to form a gripping space 106.

[0042] Analysis shows that, among the drive assembly 3, dust collection mechanism 4, and power supply mechanism 5, the drive assembly 3 has the greatest weight. Therefore, by placing the drive assembly 3 inside the main body and at the rear of the main body, and by placing the dust collection mechanism 4 at the front of the drive assembly 3, the axis of the drive assembly 3 is collinear with the axis of the dust collection mechanism 4, thus balancing the weight of the drive assembly 3 to a certain extent.

[0043] In this application, by placing the power supply mechanism 5, which is connected to the main body, below the dust collection mechanism 4, the weight of the drive component 3 can be further balanced, making the center of gravity of the whole machine closer to the middle position. This makes the cleaning host provided by this application more labor-saving to use and improves the user experience.

[0044] Furthermore, during use, the air containing dust, hair, and other dirt is filtered by the dust collection mechanism 4 and then discharged through the second channel formed by the drive component 3. Since the axis of the drive component 3 in this application is collinear with the axis of the dust collection mechanism 4, the center of the air outlet 4021 of the dust collection mechanism 4 in this application can be located on the axis of the second channel. This allows the filtered air to be discharged quickly, reducing wind resistance and increasing suction power. It also prevents the gas from turning or being blocked during the discharge process, thereby reducing noise to a certain extent and providing users with a better user experience.

[0045] It is understood that the drive component 3 in this application includes at least a motor and a fan. The motor can drive the fan to move to generate suction, draw air in through the first channel 101, and generate a rotating airflow in the dust collection mechanism 4, thereby achieving the separation of dirt such as dust and hair carried by the drawn-in air from the air.

[0046] After being separated and filtered by the dust collection mechanism 4, the air enters the second flow channel formed by the drive assembly 3 through the air outlet 4021 of the dust collection mechanism 4, and is finally discharged through the second flow channel, thus completing the absorption of dirt from the external environment.

[0047] Since the main body of this application has a gripping part, and the gripping part is located below the drive assembly 3 and behind the power supply mechanism 5, the center of gravity of the cleaning host after assembling the power supply mechanism 5 and the dust collection mechanism 4 can be closer to the center position, thereby further optimizing the user experience.

[0048] It should be noted here that the front end, bottom, and back of this application are all in accordance with... Figure 1 and Figure 2Based on the direction and angle shown in the figure, when the cleaning host provided in this application is placed horizontally with the direction shown in the figure as the reference, it can be understood that after the dust collection mechanism 4 is connected to the main body, the dust collection mechanism 4 is located at the front end of the drive component 3. Correspondingly, the axis of the first channel 101 in this application is parallel to the axis of the dust collection mechanism 4, and the first channel 101 is located below the dust collection mechanism 4. The axis of the power supply mechanism 5 is parallel to the first channel 101 and is located below the first channel 101.

[0049] It is understood that since the dust collection mechanism 4 in this application is detachably connected to the main body, when the dust collection mechanism 4 is full of dust and other debris, the dust collection mechanism 4 can be detached from the main body, thereby facilitating the cleaning of dust and other debris inside the dust collection mechanism 4.

[0050] It is necessary to further explain here that, such as Figure 3 Combination Figure 4 As shown, the first channel 101 in this application is a cylindrical channel. Therefore, in actual use, the cleaning unit provided by this application can directly perform vacuuming operations, or it can be used with different functional heads to achieve different functions. For example, it can be connected to a vacuum cleaner head, a soft brush, or a mite removal head to achieve vacuuming and mite removal functions for items such as beds, sofas, and keyboards, or it can be connected to a mopping head or a sweeping head to achieve sweeping or wiping of the floor in the room. When sweeping or mopping is required, there is also an extension rod between the cleaning unit and the functional head, which allows the user to use it in an upright position as much as possible, improving user comfort.

[0051] Optionally, such as Figures 1-3 As shown, the gripping part in this application includes a handle 102, a connecting section 103, and a transition section 104; one end of the connecting section 103 is connected to one end of the handle 102, and the other end is connected to the main body mechanism; the other end of the handle 102 is connected to the transition section 104; the handle 102 is inclined, the connecting section 103 is horizontal, and the angle between the axis of the handle 102 and the axis of the connecting section 103 is in the range of 66°-82°; the transition section 104 is inclined. The handle 102 is arc-shaped, forming a first transition arc surface 1022 with a radius ranging from 11mm to 28mm between the side of the handle 102 facing the gripping space 106 and the transition section 104 and the main body mechanism; the side of the handle 102 away from the gripping space 106 forms a second transition arc surface 1023 with a radius ranging from 3mm to 19mm between the side of the handle 102 and the transition section 104; the end of the handle 102 also forms a transition surface 1021 with an angle of 56.5° to 71.5° with the axis of the handle 102.

[0052] Firstly, the connecting section 103, in conjunction with the mounting groove 105 of the main body 1 on the side wall opposite to the power supply mechanism 5 and the handle 102, forms a closed gripping space 106. This eliminates the need for the user to grip forcefully; simply keeping four fingers wrapped around the handle 102, and further maintaining the thumb's interlocking position with the other four fingers, effectively prevents the user's hand from detaching from the grip, thus reducing the risk of the cleaning unit falling. Furthermore, the closed gripping space 106 provides more surface area for force application, regardless of how the user operates the cleaning unit, thus dispersing localized pressure on the hand and improving the user experience.

[0053] Secondly, with Figure 1 and Figure 2 Based on the angles and directions shown, when the cleaning unit is in a horizontal position, the connecting section 103 in this application is parallel to the horizontal plane. Furthermore, by tilting the handle 102, it is possible to make the handle 102 more parallel to the ground during use, thereby preventing the user's hands and arms from bending to a certain extent, and further improving the user's comfort.

[0054] Preferably, the angle between the axis of the means 102 and the axis of the connecting segment 103 in this application is 74°, so that it can be closer to a state parallel to the ground.

[0055] More preferably, such as Figure 1 As shown, in this application, a first transition arc surface 1022 with a radius of 19.33 mm is formed at the positions corresponding to the connection between the handle 102 and the transition section 104 in the grip space 106, and the connection between the transition section 104 and the main body 1. Since the cross-section of a finger is close to a circle, the first transition arc surface 1022 further reduces the local pressure received by the user's fingers, thereby further improving the user's grip experience. Correspondingly, a second transition arc surface 1023 with a radius of 11.55 mm is also formed at the connection position between the side of the handle 102 away from the grip space 106 and the transition section 104, thereby reducing the pressure on the web of the hand during use and improving the grip experience.

[0056] It is understandable that, such as Figure 1 As shown, in this application, the end of the handle 102 away from the transition section 104 is also formed with an inclined transition surface 1021, and preferably, the angle between the transition surface 1021 and the axis of the handle 102 is 64°. The formed transition surface 1021 can, to a certain extent, narrow the edge of the handle 102, thereby reducing the risk of the user's hand being bumped.

[0057] It should be added here that the transition section 104 mentioned above in this application is located between the means 102 and the drive component 3, and is also designed with an inclination. Furthermore, the fact that the transition section 104 mentioned above in this application is arc-shaped can be understood as the two ends of the transition section 104 gradually converge toward the middle in the width direction of the cleaning host, forming an arc-shaped outer wall surface.

[0058] Optionally, such as Figures 1-4 As shown, the main body structure provided in this application includes a main body 1 and an air outlet filter assembly 2; the main body 1 has a receiving portion, the drive assembly 3 is disposed in the receiving portion, the air outlet filter assembly 2 is connected to the main body 1 and is located at the end of the drive assembly 3 away from the dust collection mechanism 4; the air outlet filter assembly 2 has an air outlet hole 2011, and the end of the second channel away from the dust collection mechanism 4 is connected to the air outlet hole 2011.

[0059] like Figures 1-4 As shown, the air outlet filter assembly 2 in this application is located behind the drive assembly 3. Since the air outlet filter assembly 2 has an air outlet hole 2011 formed on it, and the end of the second channel away from the dust collection mechanism 4 can be connected to the air outlet hole 2011, the gas filtered by the dust collection mechanism 4 passes through the second channel formed by the drive assembly 3 and is finally discharged through the air outlet hole 2011.

[0060] The receiving portion formed by the main body 1 in this application can stably support the drive component 3, and as... Figure 4 As shown, when the drive assembly 3 is placed inside the receiving part, a portion of the tail of the motor in the drive assembly 3 is still exposed outside the receiving part. Therefore, the tail of the motor can be further protected by the cooperation between the air outlet filter assembly 2 and the main body 1.

[0061] Since the end of the second channel is the end of the motor, and the end of the motor is located inside the air outlet filter assembly 2, the air outlet 1011 of the second channel can be closer to the air outlet 2011, thereby reducing the length of the gas flow channel, reducing wind resistance, and improving the dust collection effect to a certain extent.

[0062] It is understandable that, such as Figure 3 Combination Figure 4 As shown, in this application, a speed control button 108 and a display screen 109 are formed on the outer wall surface of the main body 1 corresponding to the receiving part. The speed control button 108 can adjust the speed of the motor, thereby adjusting the suction power. The display screen 109 can display information such as battery level, gear, and mode, so that the user can clearly see the status of the cleaning main unit.

[0063] Preferably, the air outlet filter assembly 2 provided in this application includes a first housing 201 and a first filter element 202; there are multiple air outlet holes 2011, which are arranged in an array and formed on both sides of the first housing 201; the first filter element 202 is disposed inside the first housing 201, and a first mating part is formed on the inner wall surface of the first housing 201, and a second mating part 107 is formed on the main body 1 at the position corresponding to the first housing 201, and the first mating part and the second mating part 107 cooperate to make the first housing 201 and the main body 1 detachably connected.

[0064] The air outlets 2011 arranged in an array on both sides of the first outer casing 201 serve both to exhaust air and to enhance the aesthetics of the cleaning unit.

[0065] Furthermore, the first filter element 202 provided inside the first housing 201 can further filter the gas discharged from the motor, thereby making the gas discharged from the air outlet 2011 cleaner.

[0066] Considering that the first filter element 202 needs to be replaced or cleaned after long-term use, this application forms a first mating part on the inner wall surface of the first housing 201 and a second mating part 107 at the position of the main body 1 corresponding to the first housing 201, thereby enabling a detachable connection between the first housing 201 and the main body 1, thereby improving the convenience of replacing the first filter element 202.

[0067] It is understood that the first mating part and the second mating part 107 mentioned above in this application can be connected by a snap-fit ​​or a magnetic attraction. However, preferably, both the first mating part and the second mating part 107 in this application are threaded. The first mating part can be an internal thread or an external thread. Correspondingly, when the first mating part is an internal thread, the second mating part 107 is an external thread, and when the first mating part is an external thread, the first mating part is an internal thread. Thus, the first outer shell 201 can be disassembled by screwing.

[0068] More preferably, such as Figure 2 Combination Figure 6 As shown, in this application, a recess is formed on the end face of the first housing 201 away from the main body 1. A start button 203 is provided at the lowest position in the recess. The connection end 2031 of the start button 203 passes through the first housing 201 and can abut against or separate from the start button of the drive assembly 3.

[0069] By forming a recess in the first housing 201 and setting the start button 203 at the lowest position of the recess, the probability of accidental activation of the start button 203 can be reduced to a certain extent, thereby reducing the problem of the drive component 3 starting or stopping due to accidental activation during use or transportation.

[0070] It is understood that the start button 203 mentioned above in this application is the start button 203 of the drive component 3. When the start button 203 is pressed, the connection end 2031 of the start button 203 can abut against the start button on the drive component 3, thereby realizing the start of the drive component 3.

[0071] Optionally, such as Figure 4 As shown, in this application, the main body 1 has a mounting groove 105 formed at the position corresponding to the power supply mechanism 5. One end of the power supply mechanism 5 is inserted into the mounting groove 105, and the power supply mechanism 5 and the mounting groove 105 are detachably connected.

[0072] The mounting groove 105 formed by the main body 1 can better support the power supply mechanism 5, and by making the power supply mechanism 5 detachably connected to the mounting groove 105, it is easy to charge the power supply mechanism 5 and reduce the limitations caused by charging.

[0073] Preferably, such as Figure 2 Combination Figure 4 and Figure 5 As shown, the power supply mechanism 5 in this application includes a power source and a second housing 501. The power source is disposed inside the second housing 501. A guide protrusion 5011 extending in the insertion direction is formed on the second housing 501. A guide groove is formed in the mounting groove 105 at the position corresponding to the guide protrusion 5011. A locking part 5012 and a pressing part 5013 are formed at the end of the guide protrusion 5011. One end of the locking part 5012 protrudes from the guide protrusion 5011. A positioning part is formed in the mounting groove 105 at the position corresponding to the locking part 5012. The end of the locking part 5012 protruding from the guide protrusion 5011 can be locked into the positioning part. The pressing part 5013 is connected to the other end of the locking part 5012, and pressing the pressing part 5013 can drive the end of the locking part 5012 protruding from the guide protrusion 5011 to retract.

[0074] In this application, guide protrusions 5011 are formed on both sides of the second outer shell 501. Correspondingly, guide grooves are formed with guide protrusions 5011. Through the cooperation of guide protrusions 5011 and guide grooves, the power supply mechanism 5 can be stably inserted into the guide groove.

[0075] Since the guide protrusion 5011 in this application has a locking part 5012 and a pressing part 5013 formed sequentially at its end, and a positioning part is formed in the guide groove corresponding to the position of the locking part 5012, when the power supply mechanism 5 is inserted into the position, the locking part 5012 can be locked into the positioning part, thereby making the power supply mechanism 5 and the main body 1 stably connected.

[0076] When it is necessary to disassemble the power supply mechanism 5, the pressing part 5013 can drive the locking part 5012 to retract into the second housing, thereby enabling the locking part 5012 to disengage from the positioning part, and thus enabling the separation of the power supply mechanism 5 from the main body 1.

[0077] Understandably, when disassembling the power supply mechanism 5, it is necessary to continuously press the push part 5013 first, and then release the push part 5013 after pulling it out a certain distance so that the locking part 5012 is disengaged from the positioning part.

[0078] More preferably, such as Figure 5 Combination Figure 7 As shown, the second housing 501 in this application also has a foolproof protrusion 5014, which extends along the insertion direction, and the mounting groove 105 has a positioning recess 1051 corresponding to the position of the foolproof protrusion 5014.

[0079] Since the guide protrusions 5011 are disposed opposite to each other on both sides of the second housing 501 in this application, in order to avoid incorrect insertion direction of the power supply mechanism 5, the second housing 501 in this application also has a foolproof protrusion 5014. Correspondingly, the mounting groove 105 forms an alignment recess 1051 corresponding to the position of the foolproof protrusion 5014, so that the direction of insertion of the power supply mechanism 5 into the mounting groove 105 is unique.

[0080] It is understood that the alignment recess 1051 in this application can extend any distance along the insertion direction, and the extension dimension of the alignment recess 1051 can be consistent with the guide groove, so as to play both the role of preventing mistakes and the role of guiding.

[0081] It is understood that in this application, the end of the second housing 501 inserted into the mounting groove 105 has a power transmission part, and the inside of the mounting groove 105 has a conductive part corresponding to the position of the power transmission part. When the power supply mechanism 5 is inserted into the mounting groove 105, the power transmission part can contact the conductive part, thereby connecting the power supply and providing power to the drive assembly 3.

[0082] Accordingly, such as Figure 5 As shown, the second housing 501 in this application also has an indicator light 5015 and a charging port 5016, with the charging port 5016 located at the end of the second housing 501 away from the power transmission part, and the indicator light 5015 located on the side of the second housing 501.

[0083] The color of indicator light 5015 can reflect the power level or charging status. For example, when indicator light 5015 is red when not charging, it means that the power is insufficient. If it is blue, it means that the power is sufficient. Similarly, when charging, indicator light 5015 is red to indicate that the power is charging, and when indicator light 5015 is blue, it means that the power is fully charged.

[0084] Optionally, such as Figure 1 Combination Figure 2 As shown, the dust collection mechanism 4 in this application includes a dust cup 401 and a filter assembly 402. The filter assembly 402 is disposed inside the dust cup 401 and is spaced apart from the inner wall of the dust cup 401 to form an air guide channel 403. An air inlet 4011 is formed on the dust cup 401, which is connected to the air outlet 1011 of the first channel 101. The filter assembly 402 has an air outlet 4021, which is connected to one end of the second channel.

[0085] In this application, the dust cup 401 can hold and absorb dust, hair, and other dirt. By spaced apart from the inner wall of the dust cup 401, the dirty gas can enter the dust cup 401 and move around the filter assembly 402. Thus, the dust and other dirt are separated from the air through the filtration of the filter assembly 402. The separated dirt remains in the dust cup 401, while the separated air enters the second flow channel through the filter assembly 402 and is finally discharged through the exhaust port.

[0086] It should be added here that, preferably, such as Figure 2 As shown, this application also provides a second filter element 4022 at the air outlet 4021. The second filter element 4022 can filter the gas entering the second channel once. Since the gas needs to pass through the first filter element 202 as well, it can be filtered twice by the first filter element 202, thereby further improving the air quality discharged outdoors.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
