[0002] A garment steamer is a household appliance that uses high-temperature steam to soften clothing fibers and then uses actions such as "pulling, pressing, and spraying" to smooth the clothes while they are hanging. The core principle is to use a built-in heater to convert water into high-temperature steam, which is then sprayed onto the surface of the clothes through a nozzle to quickly remove wrinkles. It also has functions such as sterilization and deodorization.

[0003] In the prior art, garment steamers typically include a heating spray component and an air suction component that work together. The air suction component is used to absorb the clothes so that the heating spray component can spray high-temperature steam onto the clothes to remove wrinkles.

[0038] See Figures 1 to 4 As shown in the embodiment of this application, an air intake assembly is provided, which includes: a housing 1 and a negative pressure device 2;

[0039] For example, the negative pressure device 2 can be a fan-type negative pressure device 2 or a fan-type negative pressure device 2.

[0040] Of course, the above description of the negative pressure device 2 is merely illustrative, intended to illustrate a possible implementation to aid in understanding the technical solution of this application. This application does not impose any limitations on the specific type of the negative pressure device 2. In practical applications, the negative pressure device 2 can be configured according to actual needs, and all such configurations should be covered within the scope of protection of this application.

[0041] The housing 1 is enclosed to form an intake chamber 11, a transition chamber 12 and an exhaust chamber 13 connected in sequence. One end of the housing 1 is provided with an air inlet 10 connected to the intake chamber 11, and the other end is provided with an air outlet 14 connected to the exhaust chamber 13, so as to form a multi-stage airflow channel from the air inlet 10 to the air outlet 14.

[0042] The negative pressure device 2 is located in the exhaust chamber 13 and is coaxially arranged with the exhaust chamber 13. It is used to drive the airflow to enter from the air inlet 10, pass through the air intake chamber 11, the transition air chamber 12 and the exhaust chamber 13, and flow out from the air outlet 14.

[0043] The multi-stage airflow channel design allows the airflow speed to meet the usage requirements of different areas, improving the availability of airflow. The coaxial arrangement of the negative pressure device 2 and the exhaust chamber 13 helps to improve the airflow direction and reduces the obstruction of the airflow by the inner wall of the housing 1 to a certain extent, so that the power of the pneumatic device can be effectively utilized and energy loss can be reduced.

[0044] The extension direction of the transition air chamber 12 is set at an angle to the extension direction of the exhaust chamber 13;

[0045] When the angle is between 150 and 180 degrees, the airflow direction is relatively gentle, and the water vapor interception effect is poor; when the angle is between 80 and 100 degrees, the airflow movement is significantly blocked, and the airflow is not smooth. When the angle is between 120 and 140 degrees, the steam can be condensed due to inertial collision with the cavity wall without excessively obstructing the airflow, thus achieving a balance between water vapor separation efficiency and air intake efficiency.

[0046] Understandably, the extension direction of the transition air chamber 12 is set at an angle to the extension direction of the exhaust chamber 13, thereby changing the airflow direction. When air containing high-temperature steam flows through the transition air chamber, the airflow direction changes due to the angle. The steam rises and collides with the inner wall of the shell 1 due to inertia, and the droplets are thrown towards the wall due to their higher density, thus intercepting water vapor and reducing the amount of steam entering the exhaust chamber 13. This keeps the exhaust chamber 13 dry, thereby reducing the corrosion of the negative pressure device 2 by water vapor and extending the service life of the negative pressure device 2 to a great extent.

[0047] Furthermore, the angled design of the transition air chamber 12 redirects the airflow to disperse its energy, which can suppress airflow pulsation caused by impeller disturbance in the negative pressure device 2 to a certain extent, reducing the frequency of suction fluctuations and improving the adsorption stability of the suction component on clothing. In addition, the multi-stage airflow channel structure formed by the suction chamber 11, the transition air chamber 12, and the exhaust chamber 13 extends the airflow path, further reducing the amount of steam reaching the negative pressure device. At the same time, it saves space occupied by the suction component and improves the effective space utilization rate.

[0048] Specifically, in some embodiments of this application, the axis of the exhaust chamber 13 is higher than the axis of the intake chamber 11. When the airflow turns, the droplets are impacted by the inertia due to the density difference. The high-level exhaust chamber 13 prolongs the droplet residence time and enhances the gas-liquid separation effect, thereby further reducing the possibility of water vapor corroding the negative pressure device 2.

[0049] Furthermore, a water collection tank (not shown in the figure) can also be provided inside the shell 1 to collect and treat condensate.

[0050] In an optional embodiment, the intake chamber 11 is flat and the exhaust chamber 13 is cylindrical, with the cross-sectional width gradually decreasing from the intake chamber 11 to the exhaust chamber 13.

[0051] More specifically, in some embodiments of this application, the cross-sectional shape of the air intake chamber 11 includes a triangle or trapezoid, with the width gradually decreasing along the direction from the air inlet to the transition chamber.

[0052] Understandably, the air intake chamber 11 is flat and wide enough to cover a wider range of clothing, avoiding the residue of local wrinkles. The flat chamber design also reduces airflow turbulence, guides air to enter smoothly, and slows down the airflow speed, reducing fluctuations caused by airflow disturbances, making the suction force of the air intake component on clothing and other items more stable.

[0053] Furthermore, the flat design of the air intake chamber 11 helps to fit closely to the internal space of the garment steamer, maximizing the use of the limited area and avoiding increasing the overall size of the machine, thus achieving a compact design. For example, the heating spray component can be designed close to the outer surface of the housing 1 of the air intake chamber 11, wherein the surface of the housing 1 has a protrusion 181 that together with the transition chamber housing 1 forms an installation area for mounting external structures.

[0054] The gradually narrowing cross-sectional width design from the intake chamber 11 to the exhaust chamber 13 helps the airflow maintain a certain directionality and flow regularity before entering the transition chamber, improving the overall airflow efficiency of the system. It also helps the airflow to be compressed, and the flow velocity to increase naturally, which helps to improve the suction of the negative pressure device 2. The gradually narrowing channel converts static pressure into dynamic pressure, reducing the load on the negative pressure device 2.

[0055] In an optional embodiment, such as Figures 2 to 4 As shown, the housing 1 also has a first diversion port 151 communicating with the transition air chamber 12, and / or

[0056] The end of the housing 1 near the air outlet of 14 is also provided with a second diversion port 152 that communicates with the exhaust chamber 13;

[0057] A flow guide 150 is provided at the first diversion port 151 and / or the second diversion port 152.

[0058] The presence of the first diversion port 151 and the second diversion port 152 can distribute the airflow in the transition air chamber 12 to multiple directions or different areas, or introduce external airflow into the intake assembly to form one or more negative pressure areas, thereby achieving effective utilization and exchange of airflow. The guide section 150 can precisely control the direction of airflow, guiding part of the airflow to the first diversion port 151 to avoid backflow of airflow. In addition, the guide section 150 can also effectively reduce turbulence in the airflow distribution process, avoiding airflow instability or fluctuation. By smoothly guiding the airflow through the guide section 150, the airflow becomes more stable.

[0059] For example, the first diversion port 151 can be connected to the space where the main control board of the garment steamer or similar equipment is located, and the second diversion port 152 can be connected to the space where the heating spray component of the garment steamer or similar equipment is located. Under the action of the negative pressure device 2, the gas in the suction component, the gas in the space where the main control board is located, and the gas in the space where the heating spray component is located are exchanged through the first diversion port 151 and the second diversion port 152, which enhances the flow of gas and can effectively dissipate heat from the main control board, heating spray component, etc., thereby improving the overall heat dissipation capacity of the equipment, increasing heat dissipation efficiency, and optimizing heat dissipation effect.

[0060] In an optional embodiment, such as Figure 1 and Figure 4 As shown, an air intake 16 is provided at the air inlet 10 and is detachably connected to the housing 1.

[0061] The detachable design of the intake nozzle 16 and the air inlet 10 allows the intake nozzle 16 to be easily removed for cleaning and maintenance, preventing the accumulation of dust and impurities and maintaining the efficient operation of the air intake system. The intake nozzle 16 can also be replaced or adjusted to provide better adaptability according to different working environments and needs, such as adjusting the shape and size of the air inlet 10.

[0062] Optionally, a buckle can be provided in one of the air intake nozzle 16 and the housing 1, and a slot can be provided in the other. The air intake nozzle 16 and the housing 1 can be connected by inserting the buckle into the slot. Alternatively, a first magnetic attractor 161 can be provided in one of the air intake nozzle 16 and the housing 1, and a second magnetic attractor 162 or magnetic metal can be provided in the other. The air intake nozzle 16 and the housing 1 can be connected by magnetic attraction between the first magnetic attractor 161 and the second magnetic attractor 162 or by attraction with the magnetic metal.

[0063] The above are just some examples of the detachable connection between the air intake 16 and the housing 1, and do not impose specific limitations on the detachable connection method. For example, threaded connection may also be included.

[0064] Among them, after testing, the cross-sectional area of ​​the air intake nozzle 16 is not less than 3.4 cm². 2 At this time, it can achieve a good clothes adsorption effect, effectively preventing clothes from falling off, maintaining the stability of the garment steamer and the clothes, and achieving a good ironing effect. If the cross-sectional area of ​​the suction nozzle 16 is less than 3.4cm² 2 If the steam from the heating spray component does not meet the required adsorption capacity for clothing, the clothing may easily fall off when the steam from the heating spray component impacts the clothing.

[0065] In an optional embodiment, such as Figure 1As shown, the suction nozzle 16 includes a first clamping member 164 and a second clamping member 165. The first clamping member 164 is provided with a first magnetic suction member 161 or magnetic metal, and the second clamping member 165 is provided with a filter screen 17. The second clamping member 165 and the first clamping member 164 are sequentially arranged on the housing 1. The first magnetic suction member 161 and the second magnetic suction member 162 are magnetically connected to achieve a detachable connection between the first clamping member 164, the second clamping member 165 and the housing 1.

[0066] A limiting member 166 is provided on the housing 1. The limiting member 166 is detachably connected to the end of the upper housing 18 and the lower housing 19 where the air inlet 10 is provided, and is provided with a limiting hole 1661 whose shape matches the first clamping member 164 and the second clamping member 165, so as to limit the movement of the first clamping member 164 and the second clamping member 165, prevent the first clamping member 164 and the second clamping member 165 from shaking, and enhance the connection stability between the air inlet 16 and the housing 1. Specifically, the first clamping member 166... The holding member 164 is provided with a first magnetic suction member 161 or magnetic metal, and the limiting member 166 is provided with a second magnetic suction member 162. The first clamping member 164 and the second clamping member 165 are embedded in the limiting hole 1661 of the limiting member 166. The limiting member 166 is sleeved on the air inlet 10. The first magnetic suction member 161 and the second magnetic suction member 162 are magnetically connected to achieve a detachable connection between the first clamping member 164, the second clamping member 165 and the limiting member 166.

[0067] The filter 17 can intercept particulate impurities, prevent dust, sand and other impurities from entering, prevent impurities from damaging the negative pressure device 2 inside the air intake assembly, and also help maintain stable and clean airflow.

[0068] The filter screen 17 is made of multiple layers of filter media (such as metal mesh, synthetic fibers, etc.). Of course, there are no restrictions on the specific composition and materials of the filter screen 17.

[0069] In an optional embodiment, such as Figure 1 As shown, several reinforcing structures 163 are provided along the length of the air intake 16.

[0070] The reinforced structure 163 divides the intake nozzle 16 into multiple areas, splitting the intake airflow into multiple airflows. This avoids turbulence interference, resulting in a more uniform and stable airflow. Furthermore, the reinforced structure 163 enhances the structural strength and durability of the intake nozzle 16, effectively dispersing external pressure or impact forces and preventing deformation, breakage, or fatigue during high-load or long-term use. It also resists the concave deformation of the intake nozzle 16's curved surface caused by negative pressure suction. In addition, the combination of the reinforced structure 163 also plays a role in particle interception and guidance, protecting the internal structure of the intake assembly from damage.

[0071] In an optional embodiment, such as Figure 1 and Figure 2 As shown, the housing 1 includes an upper shell 18 and a lower shell 19. One of the upper shell 18 and the lower shell 19 is provided with a groove 191, and the other is provided with a protrusion 181. The upper shell 18 and the lower shell 19 are detachably connected by the protrusion 181 being embedded in the groove 191.

[0072] With the embedded design of protrusion 181 and groove 191, the upper shell 18 and lower shell 19 can be easily connected or disassembled, facilitating regular maintenance of the intake assembly.

[0073] Optionally, the upper shell 18 is provided with a protrusion 181 and the lower shell 19 is provided with a corresponding groove 191 that matches the protrusion 181, or the upper shell 18 is provided with a groove 191 and the lower shell 19 is provided with a corresponding protrusion 181 that matches the groove 191.

[0074] Of course, there are no restrictions on whether the protrusion 181 and the groove 191 are located on the upper shell 18 or the lower shell 19, as long as the detachable connection requirement is met.

[0075] The protrusions 181 and / or grooves 191 extend in the same or parallel direction as the extension direction of the housing 1.

[0076] Understandably, the combination of the protrusion 181 and the groove 191 forms a natural barrier to prevent external liquids or dust from entering, ensuring the sealing of the connection of the housing 1, reducing the impact of the external environment on the internal components of the equipment, and also helping to prevent airflow escape and improve the stability of airflow.

[0077] The design of the protrusion 181 and the groove 191, with the protrusion 181 embedded in the groove 191 to form a physical snap, resists separation force through lateral limiting, and can provide additional stability when the housing 1 is connected, thereby enhancing the structural strength of the connection. The extension direction of the protrusion 181 and the groove 191 is the same as or parallel to the extension direction of the housing 1, which increases the contact area, disperses stress concentration points, and helps to avoid local deformation of the housing 1.

[0078] In an optional embodiment, such as Figure 1 and Figure 4 As shown, the air outlet 14 is provided with a baffle 141 for blocking the flow of air, and the baffle 141 is also provided with an opening 142 for guiding the direction of airflow.

[0079] The baffle 141 and the opening 142 provided on the baffle 141 cooperate to guide the airflow in a specific direction, so that the airflow flows evenly to the predetermined position, avoids random or irregular airflow, and optimizes the airflow distribution; the baffle 141 can also reduce random fluctuations in airflow, and the design of the opening 142 can smoothly guide the airflow, thereby effectively reducing airflow turbulence and noise.

[0080] Specifically, in some embodiments of this application, the opening 142 is oriented away from the ground. Understandably, the airflow may carry a certain amount of high-temperature steam. Guiding the airflow to the side away from the handle helps to enhance safety and prevent the user from being scalded by high-temperature steam.

[0081] In an optional embodiment, such as Figure 1 As shown, the outer surface of the negative pressure device 2 is provided with an anti-slip structure 20.

[0082] Specifically, in some embodiments of this application, the anti-slip structure 20 is a raised dot, and the raised dots are distributed in an orderly manner along the outer surface of the negative pressure device 2 to form a raised dot array.

[0083] The anti-slip structure 20 enhances the surface roughness of the negative pressure device 2, thereby increasing friction. Strengthening the effective connection between the negative pressure device 2 and the housing 1 ensures that their positions remain constant, preventing displacement of the negative pressure device 2 due to driving or vibration. This reduces airflow instability caused by movement of the negative pressure device 2, thus enhancing the stability of the airflow in the suction assembly and helping to maintain effective adsorption of clothing and other items by the suction assembly.

[0084] This application also provides a garment steamer, such as Figure 5 As shown, an intake assembly including any of the items in the first part.

[0085] The garment steamer also includes a heating spray assembly, which is located on the mounting area formed by the housing 1 of the suction assembly to achieve a compact layout of the garment steamer.

[0086] The garment steamer has a detachable top cover 3 and an outer shell 4. One end of the top cover 3 extends to the air inlet 10 of the outer shell 1, and the other end extends to the air outlet 14 of the outer shell 1, thus covering the length of the outer shell 1. Most of the gas can only enter from the air inlet 10 and exit from the air outlet 14. Compared with the existing design, it can prevent the gas from escaping from the middle area of ​​the outer shell 4 to a certain extent, thereby improving the sealing of the garment steamer and enhancing the effective control of the airflow inside the garment steamer.

[0087] The embodiments of this application have at least the following beneficial effects:

[0088] This application provides an air intake assembly and a garment steamer. By constructing a multi-stage airflow channel in the air intake assembly and setting the transition air chamber 12 and the exhaust chamber 13 at an angle, effective isolation between steam and the negative pressure device 2 can be achieved, preventing steam from corroding the negative pressure device 2. Specifically, the housing 1 encloses and forms an air intake chamber 11, a transition air chamber 12, and an exhaust chamber 13 connected in sequence. The negative pressure device 2 is located in the exhaust chamber 13. The extension direction of the transition air chamber 12 is set at an angle to the extension direction of the exhaust chamber 13. The height of the central region of the exhaust chamber 13 is not lower than the height of the central region of the air intake chamber 44, thereby intercepting condensed steam and reducing direct contact between steam and the negative pressure device 2.
