Description

Technical Field

[0001] This invention relates to the technical field of electric household cleaning equipment, and more particularly to a main unit air duct and mite remover. Background Technology

[0002] A mite remover is a common household cleaning appliance that mainly uses a fan to vacuum dust and ultraviolet lamps to sterilize and remove mites from beds, quilts, or sofas.

[0003] Patent CN218651612U discloses a mite removal device, which includes a main unit with a vacuum fan and a dust collection box with a built-in filter. The main unit includes a main unit housing, with a suction port at the bottom and an air chamber for mounting the vacuum fan at the rear. The main unit housing also includes a mounting position for assembling the dust collection box, with an air inlet and an air outlet communicating with the suction port.

[0004] During operation, the vacuum fan creates negative pressure in the duct housing, generating suction to draw in air containing dust or foreign objects. The air filter inside the dust collection box separates the dust and impurities from the air, and then the treated air is discharged through the outlet.

[0005] In the aforementioned patent, the air duct at the front of the vacuum cleaner fan is assembled and connected to the housing via snap-fit ​​connections, threaded connections, fastener connections, or adhesive bonding. This creates a gap between the front and rear assembly points, necessitating the use of sealing components to ensure airtightness. Airtightness depends on the quality of these sealing components and, more importantly, on the precision of the assembly between the components. Because the vacuum cleaner fan is prone to vibration during operation, this assembly connection is susceptible to loosening, leading to poor sealing, ultimately resulting in low suction power and excessive noise.

[0072] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0073] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0074] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use.

Therefore, they should not be construed as limiting this invention.

[0075] This embodiment provides a mite removal device, such as Figure 1-3 As shown, the mite remover includes a main unit housing 100, a dust collection container 200, and a fan body 300. The dust collection container 200 is detachably mounted on the upper part of the main unit housing 100. The bottom surface of the main unit housing 100, which is in contact with the surface to be cleaned, is provided with a suction port 1. Other surfaces of the main unit housing 100 away from the bottom surface are provided with air outlets 2.

[0076] In this embodiment, as Figure 4 As shown, the main unit housing 100 is provided with the main unit air duct of the mite remover, including the front air duct component 10 and the rear air duct component 20.

[0077] like Figure 1-4 As shown, the dust collection container 200 is disposed between the front air duct component 10 and the rear air duct component 20. The front air duct component 10 is located between the dust collection container 200 and the dust suction port 1, and the rear air duct component 20 is disposed between the dust collection container 200 and the air outlet 2, thereby forming a through airflow channel from the dust suction port 1 through the dust collection container 200 to the fan body 300 and then to the air outlet 2.

[0078] like Figure 5As shown, the front air duct component 10 extends upwards and backwards at an angle. The front end of the front air duct component 10 is provided with a first airflow inlet 3, and the rear end is provided with a first airflow outlet 4. The first airflow inlet 3 is connected to the dust suction port 1, and the first airflow inlet 3 is connected to the inlet of the dust collection container 200.

[0079] The first airflow outlet 4 is higher than the first airflow inlet 3. The front air duct component 10 is hollow and has a first air duct running from the first airflow inlet 3 to the first airflow outlet 4. The first air duct is also inclined upward from front to back, and it is preferable that the first air duct is a straight air duct.

[0080] like Figure 5-6 As shown, the rear air duct component 20 includes an air duct portion 21 located on the front side and a housing portion 22 located on the rear side, which are integrally formed. The housing portion 22 is horizontally positioned in the front-to-back direction; the fan body 300 is disposed inside the housing portion 22 in the front-to-back direction; the air inlet 5 of the fan body 300 faces forward.

[0081] The air duct section 21 has a second air duct, which communicates with the inner cavity of the housing section 22. The end of the second air duct connects to the air inlet of the fan body 300. The front end of the air duct section 21 has a second airflow inlet 5, and the housing section 22 has a second airflow outlet 6. The second airflow inlet 5 connects to the outlet of the dust collection container 200; the second airflow outlet 6 connects to the air outlet 2.

[0082] One of the prominent features of the above-mentioned host air duct structure is that the air duct between the dust collection container 200 and the fan body 300 is integrally formed with the casing 22 surrounding the fan body 300.

[0083] In traditional technology, a vacuum cleaner fan consists of a housing and a fan body 300. The vacuum cleaner fan is set in an air chamber, and the air duct 21 between the dust collection container 200 and the air chamber is assembled and connected to the housing by means of snap-fit ​​connection, threaded connection, fastener connection or adhesive connection.

[0084] This creates a gap between the front and rear assembly parts, so airtightness needs to be further ensured by sealing components. Airtightness depends on the quality of the sealing components and, more importantly, on the assembly precision between the parts. Furthermore, since the vacuum cleaner fan is prone to vibration during operation, this assembly connection is susceptible to loosening, resulting in poor sealing and affecting the mite remover's airflow efficiency.

[0085] In this embodiment, the housing 22 surrounds the fan body 300, providing protection and support for the fan body 300, and replaces the original housing of the vacuum cleaner fan. It integrates the original air chamber structure and the vacuum cleaner fan housing into one unit, which not only reduces the sealing requirements between the vacuum cleaner fan and the air chamber, making it easier to ensure the airtightness of the equipment, but also reduces the number of components used, saving costs and reducing the weight of the equipment.

[0086] The integral molding of the air duct section 21 and the housing section 22 eliminates the assembly process of the air duct and air cavity, and there is no gap between the front and rear assembly. Even if the motor vibrates during operation, the two will not separate. Therefore, the assembly of the main air duct and the fan body 300 is more stable and the airtightness is better.

[0087] It should be noted that the fan body 300 and the housing 22 are circumferentially sealed, thus isolating the air inlet and outlet sides of the fan body 300. The airflow between the air inlet and outlet of the fan body 300 is ensured to pass only through the interior of the fan body 300. This sealing is also required in conventional vacuum cleaners. The second air outlet 6 is located at the rear of the housing 22, that is, on the outlet side of the fan body 300.

[0088] like Figure 4 As shown, in this embodiment, the second air duct is basically horizontally positioned, and its centerline is at the same height as the center of the air inlet 5 of the fan body 300. This ensures that the airflow entering from the second airflow inlet 5 is in a horizontal state, reducing airflow bends in the vertical direction, increasing the airflow linear velocity, thereby improving efficiency and reducing wind noise.

[0089] In this embodiment, the housing portion 22 is arranged along the centerline of the main housing 100. The first airflow outlet 4 and the second airflow inlet 5 are arranged laterally side by side, and are located on both sides of the centerline of the main housing 100.

[0090] like Figure 6 As shown, the air duct section 21 includes a first air duct section 211 on the front side and a second air duct section 212 on the rear side; a second airflow inlet 5 is provided on the upper side of the first air duct section; the rear side of the second air duct section is connected to the housing section 22 and communicates with the inner cavity of the housing section 22.

[0091] The first air duct section is relatively short and serves as a transition between the second air duct section and the dust collection container 200. Its purpose is to facilitate the connection of the second airflow inlet 5 to the dust collection container 200. Therefore, the cross-sectional size of the first air duct section depends on the size of the second airflow inlet 5, and the size of the second airflow inlet 5 depends on the corresponding connection point of the dust collection container 200.

[0092] The second air duct section extends obliquely from one side of the main housing 100 towards its centerline, and then connects to the central housing portion 22. The extension axis of the second air duct section forms an obtuse angle with the centerline of the housing portion 22. This arrangement reduces airflow obstruction and ensures smooth airflow while maintaining a reasonable center of gravity distribution.

[0093] like Figure 5 , 11As shown in Fig. -12, the front air duct member 10 is provided with a first annular end face M surrounding the first air flow outlet 4; the rear air duct member 20 is provided with a second annular end face N surrounding the second air flow inlet 5; the first annular end face M and the second annular end face N are arranged horizontally side by side and are basically located in the same plane. The first annular end face M and the second annular end face N being in the same plane is more conducive to their assembly with the main machine housing 100.

[0094] In this embodiment, as Figure 3 shown, the inner wall of the upper shell 102 of the main machine housing 100 has two through - hole docking interfaces opposite to the first air flow outlet 4 and the second air flow inlet 5. The periphery and the intervals of the two through - hole docking interfaces form a communicating recessed groove 7 adapted to the first annular end face M and the second annular end face N. A sealing member 8 is provided in the recessed groove 7. The first annular end face M and the second annular end face N are embedded into the recessed groove 7, and the first annular end face M and the second annular end face N tightly press the sealing member 8 to achieve simultaneous sealing.

[0095] Preferably, as Figure 5 shown, both the first annular end face M and the second annular end face N are in the shape of a square with a double - frame structure. Therefore, the recessed groove 7 is in the shape of a Chinese character 'ri'. The adjacent sides of the first annular end face M and the second annular end face N simultaneously tightly press the local sealing member 8 within the crossbar p of the recessed groove 7. The sealing performance at the two docking positions can be strengthened, and the sealing member at the crossbar can simultaneously seal the two docking positions.

[0096] Preferably, the first annular end face M and the second annular end face N are inclined upward from front to back. This is to adapt to the inclined dust collection container 200, so that the air flow can smoothly enter the corresponding components.

[0097] As Figure 8 shown, the rear air duct member 20 includes an upper air duct shell 20a and a lower air duct shell 20b; the upper air duct shell 20a includes an upper air duct part 21a and an upper housing part 22a; the lower air duct shell 20b includes a lower air duct part 21b and a lower housing part 22b; the upper air duct part 21a and the lower air duct part 21b enclose to form an air duct part 21; the upper housing part 22a and the lower housing part 22b enclose to form a housing part 22. The fan body 300 is assembled into the rear air duct member 20 through the disassembly and assembly of the upper air duct shell 20a and the lower air duct shell 20b.

[0098] As Figure 9 shown, the upper air duct part 21a includes the second annular end face N and an upper rear air duct wall L; the lower air duct part 21b includes a lower rear air duct wall Y. The lower rear air duct wall Y is basically parallelly arranged, which makes the second air duct of the air duct part 21 basically horizontally arranged, contributing to the transportation of the air flow. And the upper rear air duct wall L is inclined upward from front to back. In this setting, the inlet cross - section of the second air duct is larger than the outlet cross - section, forming a confluence effect and increasing the flow rate. Therefore, the inner wall of the upper rear air duct wall L has the function of confluence and flow guidance.

[0099] Preferably, the inclination angle of the upper rear air duct wall L relative to the horizontal direction is less than 5°.

[0100] As shown in the figure, the front air duct component 10 includes an upper front air duct wall 11 and a lower front air duct wall 12; both the upper front air duct wall 11 and the lower front air duct wall 12 are inclined from front to back upward so that the first air duct is inclined.

[0101] The inclination angle of the lower front air duct wall 12 is greater than that of the upper front air duct wall 11, so that the inner diameter of the first air duct gradually decreases from bottom to top. The gradually decreasing inner diameter of the air duct creates a converging effect, increases the flow velocity, and allows the external air carrying dust and impurities to quickly enter the dust collection container 200, thereby increasing the suction power of the equipment.

[0102] like Figure 6-7 As shown, the housing 22 includes a base 221 and an air outlet duct 222 extending laterally on both sides of the base 221; the second air outlet 6 is located at the end of the air outlet duct 222. Guided by the air outlet duct 222, the air blown out of the fan body 300 flows directly to the air outlet 2 of the main housing 100, thereby preventing hot air from swirling and remaining inside the equipment, which would lead to poor heat dissipation and decreased stability.

[0103] Preferably, such as Figure 9-10 As shown, the bottom of the base 221 is provided with an air passage hole f, and the two sides of the base 221 are provided with horizontally extending semi-frame protrusions 201. A U-shaped baffle 202 is sealed around the lower side and side of the base 221, thus forming an air outlet duct 222 together with the semi-frame protrusions 201 and the bottom of the base 221.

[0104] Of course, according to design requirements, an airflow outlet e is also provided at the bottom of the U-shaped baffle 202. The bottom of the main unit housing 100 is provided with an aromatherapy module 500, which uses the hot airflow from the fan body 300 to diffuse the aroma outward.

[0105] Preferably, such as Figure 4 As shown, the main unit housing 100 includes a bottom shell 101, and a first air duct component and a second air duct component are fixed to the upper side of the bottom shell 101. The lower side of the bottom shell 101 is the bottom surface of the main unit housing 100, which is the surface acting on the surface to be cleaned.

[0106] like Figure 3 As shown, the lower side of the bottom shell 101 is provided with a horizontally arranged dust suction port 1 and an ultraviolet window K. An ultraviolet germicidal lamp is located inside the ultraviolet window, through which ultraviolet light is emitted. Preferably, a roller brush T is provided inside the dust suction port 1, the brush strips of which have a beating and sweeping function for the object to be cleaned. Therefore, the bottom shell 101 of the main unit housing 100 at the dust suction port 1 forms a horizontally elongated groove with an arc-shaped bottom surface, thereby forming an arc-shaped arch 9 on the upper side of the bottom shell 101.

[0107] like Figure 3-4 As shown, the arched protrusion 9 has a front and rear side that appear to be essentially one unit. The first air duct component is connected to the rear side of the arched protrusion 9. The arched protrusion 9 has an arc-shaped interface 91 that connects to the first airflow inlet 3. The first airflow inlet 3 is an open opening with an arc-shaped profile. Therefore, compared with a planar structure of the same projected area, the first airflow inlet 3 has a larger area and a better dust collection effect.

[0108] The foregoing has provided a detailed description of the main unit air duct and the mite remover provided by this invention. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand this invention and its core ideas. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this invention.
