Description

Technical Field

[0001] The present application relates to the technical field of environmental cleaning appliances, and in particular to a mite removal and dust suction device. Background Art

[0002] Mite removal vacuum cleaners are also called mite removal devices. They are used to clean dust on beds, sofas, carpets and other household surfaces, as well as allergens such as bacteria, viruses, mites, etc. When using a mite removal vacuum cleaner for cleaning, the mite removal vacuum cleaner comes into contact with the surface of the household, thereby sucking dust and allergens such as bacteria, mites, etc. into the mite removal vacuum cleaner.

[0003] The mite-removing vacuum cleaner in the related technology includes a base, a dust cup and a negative pressure component. The dust cup is provided with a first air inlet and a first air outlet. Correspondingly, a second air inlet and a second air outlet are provided on the side of the base facing the dust cup. The first air inlet is connected to the second air inlet correspondingly, and the first air outlet is connected to the second air outlet correspondingly. An air duct is provided in the base for connecting the second air outlet and the negative pressure component, so that the fluid flows through the base, the dust cup and the negative pressure component in sequence, and then the suction force generated by the negative pressure component is used to suck dust mites, hair, etc. on the surface of the household into the dust cup.

[0004] However, since the first air inlet and the first air outlet are arranged side by side at the front end of the dust cup, the air duct needs to be arranged at the front end of the base, thereby increasing the height of the front end of the mite removal vacuum cleaner. Utility Model Content

[0005] Based on this, the present application provides a mite removal and dust suction device to solve the deficiencies in the related art.

[0006] The dust removal device provided by the present application comprises a dust cup assembly and a device host, the device host comprises a shell, the dust cup assembly is detachably connected to the shell, the dust cup assembly comprises a dust collecting cup, the dust collecting cup has an air inlet, an air outlet and a cyclone chamber, and the air inlet and the air outlet are both connected to the cyclone chamber;

[0007] The air inlet and the air outlet are arranged at intervals along the moving direction of the mite removal and dust suction device.

[0008] The dust mite removal and suction device provided in the embodiment of the present application is provided with a shell for installing a dust cup assembly, a dust cup for collecting dust mites, a cyclone chamber for cyclone separation of dust mites and gas, an air inlet for dust mites and gas to enter the cyclone chamber, and an air outlet for gas to discharge from the cyclone chamber, and the air inlet and the air outlet are arranged at intervals along the travel direction of the dust mite removal and suction device so that the air outlet duct connecting the air outlet and the fan assembly is located in the middle or rear end of the shell, thereby avoiding increasing the height of the front end of the shell, thereby making the appearance of the dust mite removal and suction device more beautiful.

[0009] In a possible implementation, the dust cup assembly also includes a cyclone separation unit, which is arranged in the cyclone chamber. The cyclone separation unit includes a cyclone barrel, and the connecting direction of the air inlet and the air outlet is parallel to the axial direction of the cyclone barrel, or the connecting direction of the air inlet and the air outlet is set at an angle to the axial direction of the cyclone barrel.

[0010] In this way, the air inlet and the air outlet can be arranged roughly along the axial direction of the cyclone, so that after the dust cup assembly is installed to the shell, the air inlet is close to the front end of the dust cup and the air outlet is close to the rear end of the dust cup.

[0011] In a possible implementation, the axial direction of the cyclone barrel is parallel to the central axis plane of the shell, or the axial direction of the cyclone barrel is arranged at an angle to the central axis plane of the shell.

[0012] In this way, after the dust cup assembly is installed on the shell, the dust cup can be placed along the front and rear direction of the mite removal and dust suction device, so that the air inlet is close to the front end of the dust cup and the air outlet is close to the rear end of the dust cup.

[0013] In a possible implementation, the air inlet and the air outlet are located at opposite ends of the dust cup along the axial direction of the cyclone.

[0014] In this way, the airflow can flow along the axial direction of the cyclone, and the gas can flow into one end of the dust cup and out of the other end. The gas does not need to make multiple turns in the dust cup during flow, thereby improving the smoothness of the gas flow and reducing the noise generated during gas flow.

[0015] In a possible implementation, the air inlet and the air outlet are located on the same side wall of the dust cup.

[0016] In this way, the air inlet and the air outlet can be arranged facing the shell at the same time, so that the gas flows directly between the shell and the dust cup, and the air flow directions of the air inlet and the air outlet can be tangent to the circumference of the cyclone.

[0017] In a possible implementation, the axial direction of the cyclone is parallel to the travel direction of the mite removal and dust suction device;

[0018] Alternatively, the axial direction of the cyclone barrel and the moving direction of the mite removal and dust suction device have a first angle, wherein the first angle is less than or equal to 80°.

[0019] In this way, the dust cup assembly can be arranged along the front and rear direction of the mite removal dust suction device, and then the air inlet and the air outlet can be arranged toward the shell, thereby shortening the flow distance of the gas between the air outlet and the fan assembly.

[0020] In a possible implementation, the device host also includes a fan assembly, which is disposed in the shell. The fan assembly is located at the rear end of the travel direction of the mite removal and dust suction device, and the air outlet is connected to the fan assembly.

[0021] In this way, the fan assembly can provide suction force for the mite removal and dust suction device, so that the dust mites enter the cyclone chamber along with the gas through the air inlet, so as to separate the dust mites and the gas in the cyclone chamber. The gas can enter the fan assembly through the air outlet and then be discharged from the fan assembly. The fan assembly is arranged at the rear end of the shell, which is conducive to the stability of the center of gravity of the mite removal and dust suction device.

[0022] In a possible implementation, the air outlet is located at one end of the dust cup facing the fan assembly.

[0023] In this way, the distance between the air outlet and the fan assembly can be shortened, thereby shortening the distance that the gas flows from the air outlet to the fan assembly.

[0024] In a possible implementation, the cyclone separation unit also includes a cyclone channel, which is arranged in an axial spiral around the cyclone barrel, the first end of the cyclone channel is connected to the air inlet, the second end of the cyclone channel is connected to the outside of the cyclone barrel, and the end of the cyclone barrel facing away from the cyclone channel is connected to the air outlet.

[0025] In this way, the gas flows along the cyclone channel to form a spiral airflow, and then rotates around the circumference of the cyclone barrel, thereby generating centrifugal force to cyclonically separate the dust mites and the gas, thereby improving the dust and gas separation effect of the cyclone separation unit.

[0026] In a possible implementation, the dust cup assembly also includes a filter element, which is located in the cyclone barrel and is coaxially arranged with the cyclone barrel.

[0027] In this way, by providing a filter, the gas entering the inner side of the cyclone can be further filtered to prevent the gas subsequently entering the fan assembly from containing more dust, thereby preventing dust from accumulating in the fan assembly.

[0028] In a possible implementation, the dust cup further has a dust storage chamber, which is connected to the cyclone chamber, and the dust storage chamber and the cyclone chamber are arranged side by side along the radial direction of the cyclone barrel.

[0029] In this way, after the dust mites and gas are fully separated in the cyclone chamber, the gas can continue to flow, and the dust mites can be collected in the dust storage chamber to avoid the cyclone being blocked, and then they can be cleaned uniformly after the dust storage chamber is full.

[0030] In a possible implementation, the device host also includes a cleaning component, and the cleaning component and the fan component are arranged at intervals along the travel direction of the mite removal and dust suction device. The cleaning component is rotatably connected to the shell, and the air inlet is connected to the cleaning component.

[0031] In this way, the cleaning component can be used to brush the surface to be cleaned, or to pat the surface to be cleaned to expose dust mites hidden deep inside the surface to be cleaned. The fan component is used to provide suction force so that when the user pushes the mite removal vacuum device to move on the surface to be cleaned, the mite removal vacuum device can suck away the dust mites on the surface to be cleaned.

[0032] In one possible implementation, the shell has an air inlet, an air outlet and a mounting slot, the cleaning component is rotatably disposed in the mounting slot, the air inlet is connected between the mounting slot and the air inlet, and the air outlet is connected between one end of the fan component facing the cleaning component and the air outlet.

[0033] In this way, the gas enters from the installation groove, passes through the air inlet, air inlet, cyclone duct, cyclone barrel, filter, air outlet and air outlet duct in sequence, then reaches the fan assembly, and is finally discharged from the heat dissipation port of the shell, thus forming a relatively complete gas flow path.

[0034] In a possible implementation, the dust collecting cup includes a cup body and a cup cover, the cup cover is connected to the cup body to jointly define a cyclone chamber and a dust storage chamber, the air inlet is located on the cup body, and the air outlet is located on the cup cover.

[0035] In this way, when the dust cup assembly needs to be cleaned, the cup cover can be opened to expose the cyclone chamber and the dust storage chamber, thereby facilitating the cleaning of the dust cup assembly. The air inlet is set on the cup body and the air outlet is set on the cup cover, so that the air inlet and the air outlet are located at opposite ends of the dust cup.

[0036] In addition to the technical problems solved by the embodiments of the present application described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the mite removal and dust collection device provided by the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0045] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0048] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0049] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0050] The mite-removing vacuum cleaner in the related technology includes a base, a dust cup and a negative pressure component. The dust cup is provided with a first air inlet and a first air outlet. Correspondingly, a second air inlet and a second air outlet are provided on the side of the base facing the dust cup. The first air inlet is connected to the second air inlet correspondingly, and the first air outlet is connected to the second air outlet correspondingly. An air duct is provided in the base for connecting the second air outlet and the negative pressure component, so that the fluid flows through the base, the dust cup and the negative pressure component in sequence, and then the suction force generated by the negative pressure component is used to suck dust mites, hair, etc. on the surface of the household into the dust cup.

[0051] However, since the first air inlet and the first air outlet are arranged side by side at the front end of the dust cup, the air duct needs to be arranged at the front end of the base. Since the air duct needs to occupy a certain space, the height of the front end of the mite removal vacuum cleaner is increased.

[0052] In view of this, an embodiment of the present application provides a mite removal dust suction device, in which a dust collecting cup is arranged along the front and rear direction of the mite removal dust suction device, and the air inlet and air outlet of the dust collecting cup are arranged at intervals along the front and rear direction of the mite removal dust suction device, so that there is no need to set an air duct pipe at the front end of the shell to connect the air outlet and the fan assembly of the device host, thereby effectively reducing the front end height of the shell, thereby making the appearance of the mite removal dust suction device more beautiful.

[0053] The specific implementation of the mite removal and dust collection device provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 4 As shown, the mite removal and dust suction device provided in the embodiment of the present application includes a dust cup assembly 100 and a device main body 200, the device main body 200 includes a shell 210, the dust cup assembly 100 is detachably connected to the shell 210, the dust cup assembly 100 includes a dust cup 110 and a cyclone separation unit 120, the dust cup 110 has an air inlet 111, an air outlet 112 and a cyclone chamber 113, the cyclone separation unit 120 is arranged in the cyclone chamber 113, and the air inlet 111 and the air outlet 112 are both connected to the cyclone chamber 113.

[0055] The cyclone separation unit 120 includes a cyclone barrel 121, and an air inlet 111 and an air outlet 112 are arranged at intervals along the moving direction of the mite removal and dust suction device.

[0056] In the present application, the device main body 200 is used to contact the surface to be cleaned and generate suction force to suck away dust mites and the like on the surface to be cleaned, and the dust cup assembly 100 is used to separate dust mites and gas and to collect dust mites.

[0057] Specifically, the device host 200 may include a shell 210, the shell 210 is used to install the dust cup assembly 100, and the shell 210 has a bottom surface on the side facing away from the dust cup assembly 100, the bottom surface has a dust suction port, and the bottom surface is used to contact the surface to be cleaned. The dust cup assembly 100 may include a dust cup 110 and a cyclone separation unit 120, the cyclone separation unit 120 is used for cyclone separation of dust mites and gas, and the dust cup 110 is used to collect dust mites and other debris.

[0058] When the user pushes the dust mite removal device to move back and forth on the surface to be cleaned, under the suction force of the device main body 200, the dust mites are sucked into the cyclone chamber 113 through the air inlet 111 together with the gas. Afterwards, the dust mites rotate around the cyclone barrel 121 with the gas, and then the dust mites and the gas are separated by centrifugal force. The dust mites are blocked outside the cyclone barrel 121 and then collected in the dust cup 110, while the gas continues to flow and then flows out of the dust cup 110 through the air outlet 112. The gas enters the fan assembly 220 in the shell 210 and is finally discharged from the dust mite removal device.

[0059] It is understandable that since a cleaning part such as a roller brush needs to be provided at the front end of the shell 210, and in order to balance the center of gravity of the mite removal and dust suction device, the fan assembly 220 is arranged at the middle or rear end of the shell 210. If the air inlet 111 and the air outlet 112 are arranged in parallel at the front end of the dust cup 110 in the prior art, the distance between the air outlet 112 and the fan assembly 220 is long and cannot be directly connected. They need to be connected through a longer air duct pipe, and the air duct pipe will inevitably increase the height of the front end of the shell 210.

[0060] However, the air inlet 111 and the air outlet 112 of the embodiment of the present application are arranged at intervals along the moving direction of the mite removal dust suction device. That is to say, taking the state of the mite removal dust suction device when moving as a reference, the dust cup 110 can be placed along the front and back direction of the mite removal dust suction device, and the air inlet 111 and the air outlet 112 can also be arranged at intervals along the front and back direction of the mite removal dust suction device.

[0061] For example, the air inlet 111 can be arranged near the front end of the dust cup 110, and the air outlet 112 can be located in the middle of the dust cup 110 to communicate with the fan assembly 220 located in the middle of the shell 210, or the air outlet 112 can be arranged near the rear end of the dust cup 110 to communicate with the fan assembly 220 located at the rear end of the shell 210. In this way, the air inlet 111 can be connected to the surface to be cleaned through a shorter air inlet duct 211, and the air outlet 112 can be connected to the fan assembly 220 through a shorter air outlet duct 212, and the air outlet duct 212 for connecting the air outlet 112 and the fan assembly 220 is located in the middle of the shell 210 or the rear end of the shell 210, and will not occupy the space at the front end of the shell 210, thereby effectively reducing the height of the front end of the shell 210, thereby making the appearance of the mite removal and dust suction device more beautiful.

[0062] The dust mite removal device provided in the embodiment of the present application includes a dust cup assembly 100 and a device main unit 200, the device main unit 200 includes a shell 210, the dust cup assembly 100 includes a dust cup 110 and a cyclone separation unit 120, the dust cup 110 includes an air inlet 111, an air outlet 112 and a cyclone chamber 113, and the cyclone separation unit 120 includes a cyclone barrel 121. A shell 210 is provided for installing the dust cup assembly 100, a dust cup 110 is provided for collecting dust mites, a cyclone barrel 121 and a cyclone chamber 113 are provided for cyclone separation of dust mites and gas, an air inlet 111 is provided for dust mites and gas to enter the cyclone chamber 113, and an air outlet 112 is provided for gas to be discharged from the cyclone chamber 113. By arranging the axial direction of the cyclone barrel 121 along the moving direction of the mite removal dust suction device, and by arranging the air inlet 111 and the air outlet 112 at intervals along the axial direction of the cyclone barrel 121, the air outlet 212 for connecting the air outlet 112 and the fan assembly 220 is located in the middle or rear end of the shell 210, thereby avoiding increasing the height of the front end of the shell 210, thereby making the appearance of the mite removal dust suction device more beautiful.

[0063] Since the air inlet 111 and the air outlet 112 are arranged at intervals along the traveling direction of the mite removal and dust suction device, in a specific implementation, the connecting direction of the air inlet 111 and the air outlet 112 can be parallel to the axial direction of the cyclone barrel 121, or the connecting direction of the air inlet 111 and the air outlet 112 can also be arranged at an angle to the axial direction of the cyclone barrel 121.

[0064] In this way, the air inlet 111 and the air outlet 112 can be arranged roughly along the axial interval of the cyclone barrel 121, so that after the dust cup assembly 100 is installed to the shell, the air inlet 111 is arranged close to the front end of the dust cup 110, and the air outlet 112 is arranged close to the rear end of the dust cup 110.

[0065] In some embodiments, the axial direction of the cyclone barrel 121 is parallel to the central axis of the shell 210 , or the axial direction of the cyclone barrel 121 is arranged at an angle to the central axis of the shell 210 .

[0066] That is to say, when the dust cup 110 is placed forward and backward along the direction of travel of the dust mite removal device, the axial direction of the cyclone 121 can be parallel to the central axis of the housing 210, or can be offset to the left and right direction of the dust mite removal device by a certain angle relative to the central axis of the housing 210. In this way, after the dust cup assembly 100 is installed on the housing 210, the axial direction of the cyclone 121 can be roughly along the direction of travel of the dust mite removal device, so that the air inlet 111 is arranged near the front end of the dust cup 110, and the air outlet 112 is arranged near the rear end of the dust cup 110.

[0067] Reference Figure 2 As shown, in a possible implementation, the air inlet 111 and the air outlet 112 are located at opposite ends of the dust cup 110 along the axial direction of the cyclone barrel 121 .

[0068] It can be understood that the air inlet 111 can be located at the front end of the dust cup 110, and the air inlet 111 is connected to the dust suction port, and the air outlet 112 can be located at the rear end of the dust cup 110, and the air outlet 112 is connected to the fan assembly 220. Such a configuration can make the airflow flow along the axial direction of the cyclone barrel 121. Compared with setting the air outlet 112 in the middle of the dust cup 110, the air inlet 111 and the air outlet 112 are set at the opposite ends of the dust cup 110 along the axial direction of the cyclone barrel 121. The gas can flow in from one end of the dust cup 110 and out from the other end. The gas does not need to make multiple turns in the dust cup 110 when flowing, thereby improving the smoothness of the gas flow and reducing the noise generated by the gas flow.

[0069] In some embodiments, the air inlet 111 and the air outlet 112 are both located on the side wall of the dust cup 110 , and the air inlet 111 and the air outlet 112 are located on the same side wall of the dust cup 110 .

[0070] In this way, the air inlet 111 and the air outlet 112 can be set facing the shell body 210 at the same time, so that the gas can flow directly between the shell body 210 and the dust cup 110. At the same time, the air flow directions of the air inlet 111 and the air outlet 112 can be tangent to the circumference of the cyclone barrel 121, so that the gas can rotate around the circumference of the cyclone barrel 121 after entering the cyclone chamber 113 to generate centrifugal force to separate dust mites and gas. After that, the gas enters the inner side of the cyclone barrel 121 and flows a certain distance along the axial direction of the cyclone barrel 121. Finally, the gas can flow out of the dust cup 110 in a direction tangent or approximately tangent to the circumference of the cyclone barrel 121.

[0071] The airflow direction of the air inlet 111 is opposite to the airflow direction of the air outlet 112 .

[0072] In some embodiments, the axial direction of the cyclone barrel 121 is parallel to the bottom surface of the housing 210. Alternatively, in other embodiments, the axial direction of the cyclone barrel 121 and the bottom surface of the housing 210 have a first angle, wherein the first angle is less than or equal to 80°. The first angle can be referred to Figure 1 For example, the first angle may be 15°, 30°, or 60°.

[0073] It can be understood that when the axial direction of the cyclone barrel 121 is parallel to the central axis of the shell 210, if the axial direction of the cyclone barrel 121 is set perpendicular to the moving direction of the mite removal and dust suction device, the air inlet 111 and the air outlet 112 will be set at intervals along the height direction of the mite removal and dust suction device, and the air inlet 111 is set close to the shell 210, and the air outlet 112 is set away from the shell 210. Even if the air outlet 112 can be connected to the middle or rear end of the shell 210, the flow distance of the gas between the air outlet 112 and the fan assembly 220 will be longer.

[0074] The axial direction of the cyclone barrel 121 is parallel to the moving direction of the mite removal dust suction device or has a first angle, so that the dust cup assembly 100 can be arranged along the front and rear direction of the mite removal dust suction device, and then the air inlet 111 and the air outlet 112 can be arranged toward the shell 210, thereby shortening the flow distance of the gas between the air outlet 112 and the fan assembly 220.

[0075] In a specific implementation, the first angle can be less than or equal to 30°, which can reduce the inclination of the dust cup assembly 100 relative to the moving direction of the mite removal dust suction device, so that the mite removal dust suction device is gently streamlined, thereby making the mite removal dust suction device more beautiful in appearance, and can shorten the gas flow distance between the air outlet 112 and the fan assembly 220.

[0076] Reference Figure 1 and Figure 2As shown, in a possible implementation, the device host 200 also includes a fan assembly 220, which is disposed in the shell 210, and the fan assembly 220 is located at the rear end of the travel direction of the mite removal and dust suction device, and the air outlet 112 is connected to the fan assembly 220.

[0077] In this way, the fan assembly 220 can provide suction force for the mite removal and dust suction device, so that the dust mites enter the cyclone chamber 113 along with the gas through the air inlet 111, so as to separate the dust mites and the gas in the cyclone chamber 113. The gas can enter the fan assembly 220 through the air outlet 112, and then be discharged from the fan assembly 220, and work in such a reciprocating cycle. The fan assembly 220 is arranged at the rear end of the shell 210, which is beneficial to the stability of the center of gravity of the mite removal and dust suction device.

[0078] In a specific implementation, the air outlet 112 is located at one end of the dust cup 110 facing the fan assembly 220. That is, the air inlet 111 is arranged close to the cleaning assembly 230, and the air outlet 112 is arranged close to the fan assembly 220. The air outlet 112 is located at one end of the dust cup 110 facing the fan assembly 220, which can shorten the distance between the air outlet 112 and the fan assembly 220, thereby shortening the distance of the gas flowing from the air outlet 112 to the fan assembly 220.

[0079] Reference Figure 3 As shown, in some embodiments, the cyclone separation unit 120 also includes a cyclone duct 122, which is spirally arranged axially around the cyclone barrel 121, the first end of the cyclone duct 122 is connected to the air inlet 111, the second end of the cyclone duct 122 is connected to the outside of the cyclone barrel 121, and the end of the cyclone barrel 121 facing away from the cyclone duct 122 is connected to the air outlet 112.

[0080] With such arrangement, when dust mites enter the cyclone chamber 113 along with the gas from the air inlet 111, they first flow along the cyclone duct 122 to form a spiral airflow, and then rotate around the circumference of the cyclone barrel 121, thereby generating centrifugal force to cyclone separate the dust mites and the gas. Then, the separated gas enters the inner side of the cyclone barrel 121, and flows along the axial direction of the cyclone barrel 121 to the end of the cyclone barrel 121 away from the cyclone duct 122, whereupon the flow direction is changed. Finally, the gas flows out of the dust collecting cup 110 through the air outlet 112 in a direction tangential to the circumference of the cyclone barrel 121. Such a flow pattern can improve the dust and gas separation effect of the cyclone separation unit 120.

[0081] Reference Figure 3 As shown, in a possible implementation, the dust cup assembly 100 further includes a filter element 123 , and the filter element 123 is located in the cyclone barrel 121 , and the filter element 123 is coaxially arranged with the cyclone barrel 121 .

[0082] It can be understood that the cyclone 121 can separate dust mites and gases with larger particles, but for some dust particles with smaller particles, a filter 123 is required for filtering, and the dust can be adsorbed on the filter 123. In this way, by setting the filter 123 in the cyclone 121, the gas entering the inside of the cyclone 121 can be further filtered to avoid the gas entering the fan assembly 220 subsequently containing more dust, thereby preventing dust from accumulating in the fan assembly 220.

[0083] Reference Figure 3 and Figure 4 As shown, in a possible implementation, the dust cup 110 further has a dust storage chamber 114 , the dust storage chamber 114 is connected to the cyclone chamber 113 , and the dust storage chamber 114 and the cyclone chamber 113 are arranged side by side along the radial direction of the cyclone barrel 121 .

[0084] Therefore, after the dust mites and gas are fully separated in the cyclone chamber 113, the gas can continue to flow, and the dust mites can be collected in the dust storage chamber 114 to avoid the cyclone barrel 121 from being blocked, and then they can be cleaned uniformly after the dust storage chamber 114 is full.

[0085] Reference Figure 1 As shown, in some embodiments, the fan assembly 220 includes a motor 221, and the axial direction of the output shaft of the motor 221 is parallel to the bottom surface of the housing 210. The axial direction of the output shaft of the motor 221 can be along the front-to-back direction or the left-to-right direction.

[0086] Alternatively, the axial direction of the output shaft of the motor 221 and the bottom surface of the housing 210 form a second angle, which can be referred to as Figure 1 The β angle in .

[0087] With such an arrangement, the fan assembly 220 can also be arranged along the front-to-back direction of the mite removal and dust suction device, thereby making the air outlet 112 and the fan assembly 220 adjacent to each other along the front-to-back direction of the mite removal and dust suction device, thereby shortening the distance between the air outlet 112 and the fan assembly 220, thereby reducing the length of the air outlet duct 212.

[0088] Exemplarily, the second angle is less than or equal to 15°. It is understandable that the mass of the fan assembly 220 is relatively large, and the fan assembly 220 needs to be set as close to the surface to be cleaned as possible. If the second angle between the axial direction of the output shaft of the motor 221 and the travel direction of the mite removal and dust suction device is greater than 15°, the center of gravity of the fan assembly 220 will be too high, thereby increasing the center of gravity of the mite removal and dust suction device. The above-mentioned setting method can lower the overall center of gravity of the mite removal and dust suction device, and the mite removal and dust suction device is not easy to flip over when moving.

[0089] It should be noted that the fan assembly 220 can also include a fan 222, which can be coaxially connected to the motor 221. The motor 221 can provide power for the fan 222 to drive the fan 222 to rotate. When the fan 222 rotates, it can generate suction force, thereby sucking away dust mites and the like on the surface to be cleaned.

[0090] Reference Figure 1 As shown, in a possible implementation, the device host 200 also includes a cleaning component 230, and the cleaning component 230 and the fan component 220 are arranged at intervals along the travel direction of the mite removal and dust suction device, the cleaning component 230 is rotatably connected to the shell 210, and the air inlet 111 is connected to the cleaning component 230.

[0091] Thus, the cleaning component 230 can be used to brush the surface to be cleaned, or to pat the surface to be cleaned to expose dust mites hidden deep inside the surface to be cleaned, and the fan component 220 is used to provide suction force so that when the user pushes the mite removal vacuum device to move on the surface to be cleaned, the mite removal vacuum device can suck away the dust mites on the surface to be cleaned.

[0092] Among them, the cleaning component 230 can be located at the front end of the travel direction of the mite removal dust suction device, and the fan component 220 can be located at the rear end of the travel direction of the mite removal dust suction device, so that the cleaning component 230 and the fan component 220 are arranged at intervals along the travel direction of the mite removal dust suction device.

[0093] Reference Figure 1 As shown, in some embodiments, the shell 210 has an air inlet 211, an air outlet 212 and a mounting slot 213, the cleaning component 230 is rotatably disposed in the mounting slot 213, the air inlet 211 is connected between the mounting slot 213 and the air inlet 111, and the air outlet 212 is connected between one end of the fan component 220 facing the cleaning component 230 and the air outlet 112.

[0094] In this way, the gas enters from the mounting groove 213, passes through the air inlet 211, the air inlet 111, the cyclone 122, the cyclone barrel 121, the filter 123, the air outlet 112 and the air outlet 212 in sequence, and then reaches the fan assembly 220, and finally is discharged from the heat dissipation port of the housing 210, thus forming a relatively complete gas flow path. In addition, the dust cup assembly 100 provided in the embodiment of the present application, the air inlet 111 and the air outlet 112 are arranged at intervals along the axial direction of the cyclone barrel 121, which can effectively shorten the length of the air inlet 211 and the air outlet 212.

[0095] Reference Figure 4 As shown, in a specific implementation, the dust cup 110 includes a cup body 115 and a cup cover 116 , and the cup cover 116 is connected to the cup body 115 to jointly define a cyclone chamber 113 and a dust storage chamber 114 , the air inlet 111 is located at the cup body 115 , and the air outlet 112 is located at the cup cover 116 .

[0096] With such arrangement, when it is necessary to clean the dust mites in the dust storage chamber 114, or when it is necessary to clean the cyclone barrel 121 and the filter element 123 in the cyclone chamber 113, the cup cover 116 can be opened to expose the cyclone chamber 113 and the dust storage chamber 114, thereby facilitating the cleaning of the dust cup assembly 100. The air inlet 111 is arranged on the cup body 115, and the air outlet 112 is arranged on the cup cover 116, so that the air inlet 111 and the air outlet 112 can be located at opposite ends of the dust cup 110.
