Detailed implementation manners

[0027] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will give a detailed description of the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0028] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0029] In addition, if there is a term "and / or", "and / or" is only a description of the association relationship between associated objects and indicates that there can be three relationships. For example, A and / or D can represent the association relationship between A and D: A exists alone, A and D exist simultaneously, and D exists alone. In addition, the character " / " in this article generally indicates an "or" relationship between the associated objects before and after it. If there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, four, five, etc., unless otherwise specifically defined.

[0030] In the present application, unless otherwise clearly specified and limited, if there are terms such as "installation", "connection", "connection", "fixation", etc., these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the connection inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0031] In this application, unless otherwise clearly defined and limited, if there is a description such as a first feature being "on" or "under" a second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0033] In addition to the problems described in the background art, when conducting experiments on the humidifying structure in the related art, it can also be found that there are problems such as a low fog outlet height and a large number of water droplets appearing on the fog outlet end face 11, resulting in a poor fog outlet effect.

[0034] Please refer to Figures 1 to 3 , the fog outlet structure 100 provided by an embodiment of the present application includes a fog outlet top cover 10. The fog outlet top cover 10 has a fog outlet end face 11 at its top, and the fog outlet end face 11 intersects obliquely with the horizontal plane, that is, the fog outlet end face 11 intersects with the horizontal plane but is not perpendicular, and the fog outlet end face 11 is arranged with a downward slope along the first direction forward (the first direction corresponds to the X direction shown in Figure 2 , and moving forward along the first direction corresponds to moving from left to right in the X direction). In other words, the fog outlet end face 11 presents a shape with a lower front and a higher rear, and along the first direction forward, the height of the fog outlet end face 11 gradually decreases.

[0035] The fog outlet top cover 10 also has a first inner wall 12 and a second inner wall 13 arranged opposite to each other. The first inner wall 12 is located behind the second inner wall 13, and a fog outlet channel 14 is formed by an interval between the first inner wall 12 and the second inner wall 13, and a fog outlet 15 is formed at the fog outlet end face 11. The fog outlet structure 100 also includes a diversion part 30, and the diversion part 30 is arranged at the top of at least a part of the first inner wall 12 and is used to guide the airflow in the fog outlet channel 14 forward.

[0036] The mist outlet structure 100 is used for the humidifying component 200. The humidifying component 200 can be used in a heater. The water mist generated by the humidifying component 200 is guided by the mist outlet channel 14 and flows out through the mist outlet 15. The first inner wall 12 and the second inner wall 13 face each other, and the mist outlet channel 14 is defined between the two. The mist outlet channel 14 forms the mist outlet 15 at the mist outlet end face 11, that is, the top ends of the first inner wall 12 and the second inner wall 13 jointly define the mist outlet 15. In addition, the mist outlet top cover 10 may have a set of oppositely arranged first inner walls 12 and second inner walls 13, or may have two or more sets of oppositely arranged first inner walls 12 and second inner walls 13. The mist outlet channel 14 of the mist outlet top cover 10 can be jointly defined by all the first inner walls 12 and second inner walls 13.

[0037] The second inner wall 13 is located in front of the first inner wall 12. That is, in the first direction, the first inner wall 12 is in a more rearward position. Among a set of oppositely arranged inner walls, the one located in front is the second inner wall 13, and the one located in the rear is the first inner wall 12. Since the mist outlet end face 11 is provided with a downward slope in the forward direction, that is, the top end of the first inner wall 12 is higher than the top end of the second inner wall 13. In front of the top end of the first inner wall 12 is the mist outlet 15, and behind is the inclined mist outlet end face 11.

[0038] In other words, the first inner wall 12 is the wall surface located at the rear of the mist outlet channel 14, and the diversion part 30 is located at the top end of the first inner wall 12, that is, at the rear side edge of the mist outlet 15. The diversion part 30 guiding the air flow in the mist outlet channel 14 forward means that the air flow passing through the diversion part 30 can, under its guidance, at least generate a forward component velocity.

[0039] For the above-mentioned mist outlet structure 100, its diversion part 30 can guide the mist outlet air flow forward at the edge of the mist outlet 15, change the mist outlet flow direction of the mist outlet 15, and thus weaken the wall attachment effect, making it difficult for the outflow direction of the mist outlet air flow to tilt backward. In addition, the diversion part 30 is provided at the top end of the first inner wall 12 for forming the mist outlet 15, occupying a certain space at the rear side edge of the mist outlet 15, compressing the effective flow area of the mist outlet 15, being able to increase the flow velocity of the mist outlet air flow, and also making it not easy to deflect, slowing down the phenomenon that the mist outlet air flow of the humidifying component 200 tilts backward. In this way, the mist outlet tilt angle of the mist outlet structure 100 is reduced. At the same time, thanks to the reduction of the mist outlet tilt angle and the increase of the flow velocity of the mist outlet air flow at the mist outlet 15, the mist outlet height is also increased, and the water accumulation on the mist outlet end face 11 is reduced.

[0040] Specifically, the angle between the mist outlet end face 11 and the horizontal plane is α, and 15° ≤ α ≤ 24°. In this way, the diversion part 30 can play a good role in weakening the wall attachment effect, making the mist outlet air flow flow out closer to the vertical direction.

[0041] Understandably, the angle between the mist outlet end face 11 and the horizontal plane can be designed according to the angle at the top of the heater, and the top of the heater can be profiled, which is not specifically limited here.

[0042] In some embodiments, the mist outlet channel 14 may specifically include a channel section 141 and an outlet section 142. Among them, the channel section 141 is a long and narrow channel, which plays a role in accelerating the water mist and adjusting the flow direction. The first inner wall 12 and the second inner wall 13 forming the channel section 141 are parallel to each other. The outlet section 142 forms a mist outlet 15 on the mist outlet end face 11, and the formed outlet section 142 can be in an expanding shape. At least one of the first inner wall 12 and the second inner wall 13 forming the outlet section 142 can be an arc surface or be inclined.

[0043] In some embodiments, the mist outlet top cover 10 has at least two of the first inner walls 12, and the guiding portion 30 is disposed at least on the foremost one of all the first inner walls 12.

[0044] Correspondingly, the mist outlet top cover 10 has at least two of the second inner walls 13. The second inner walls 13 are arranged corresponding to the first inner walls 12, and the numbers of both are equal. Each group of the first inner walls 12 and the second inner walls 13 are opposite to each other and can be connected to the first inner walls 12 or the second inner walls 13 of other groups. All the first inner walls 12 and the second inner walls 13 can form at least two mist outlet channels 14, or can jointly form one mist outlet channel 14.

[0045] In this way, at least at the foremost position, that is, the place where the mist outlet airflow is most affected by the rear side, can be improved by the guiding portion 30.

[0046] Specifically, the guiding portion 30 is only disposed on the foremost one of all the first inner walls 12.

[0047] When the airflows adjacent to each other have inconsistent speeds, it is easy for the low-speed side to shift to the high-speed side. Due to the inclined setting of the mist outlet end face 11, the mist outlet airflow at the front side will leave the mist outlet channel 14 at a lower height and start to decelerate. If no measures are taken, when it reaches the same height as the mist outlet airflow at the rear side, its flow rate will be less than that of the mist outlet airflow at the rear side, which will also cause the mist outlet airflow at the front side to shift to the rear side.

[0048] In this way, the mist outlet 15 is only affected by the guiding portion 30 at the foremost side and the effective flow area is reduced, thereby increasing the flow rate of the mist outlet airflow at the front side, weakening the attracting effect of the mist outlet airflow at the rear side on the mist outlet airflow at the front side, and thus making the overall mist outlet direction straight.

[0049] In some embodiments, the mist outlet top cover 10 includes an inner part 16, an outer part 17, and a diversion grille 18. The outer part 17 surrounds the inner part 16 and is spaced from the inner part 16 to form a mist outlet channel 14 therebetween. The inner part 16 and the outer part 17 are connected by the diversion grille 18.

[0050] The outer wall of the inner part 16 is divided into front and rear parts. Among them, the front part forms the first inner wall 12, and the rear part forms the second inner wall 13. The inner wall of the outer part 17 is also divided into front and rear parts. Among them, the front part is disposed opposite to the front part of the outer wall of the inner part 16 and forms the second inner wall 13, and the rear part is disposed opposite to the rear part of the outer wall of the inner part 16 and forms the first inner wall 12. It is easy to know that the mist outlet top cover 10 has a total of two sets of opposite first inner walls 12 and second inner walls 13. The first inner wall 12 of the inner part 16 is opposite to the second inner wall 13 of the outer part 17, the second inner wall 13 of the inner part 16 is opposite to the first inner wall 12 of the outer part 17, the first inner wall 12 of the inner part 16 is connected to the second inner wall 13 of the inner part 16, and the first inner wall 12 of the outer part 17 is connected to the second inner wall 13 of the outer part 17.

[0051] The mist outlet channel 14 can also be divided into a front mist outlet channel and a rear mist outlet channel. The front mist outlet channel is located between the first inner wall 12 of the inner part 16 and the second inner wall 13 of the outer part 17, and the rear mist outlet channel is located between the second inner wall 13 of the inner part 16 and the first inner wall 12 of the outer part 17. Correspondingly, the mist outlet 15 formed by the front mist outlet channel is the front-side mist outlet 151, and the mist outlet 15 formed by the rear mist outlet channel is the rear-side mist outlet 152. The diversion part 30 can be disposed at the front top end of the inner part 16.

[0052] It can be understood that the diversion part 30 can be disposed at the rear edge of the front-side mist outlet 151, that is, at the top end of the first inner wall 12 of the inner part 16.

[0053] In this way, the mist outlet top cover 10 can generally form an annular mist outlet 15, with uniform mist outlet and suitable for practical use. The inner part 16 and the outer part 17 can also be connected into a whole through the diversion grille 18, which is convenient for assembly.

[0054] Specifically, the mist outlet 15 can be, but is not limited to, in the shape of an annular runway, a circular ring, a rectangular ring, etc. It can be understood that in some other embodiments, the mist outlet 15 can also be in the shape of a strip, a hole, etc., and there can be multiple of them, which are not specifically limited herein.

[0055] In some embodiments, the depth of the channel section 141 is H, the interval between the first inner wall 12 and the second inner wall 13 at the channel section 141 is D, and H≥a·D. Among them, 3.75≤a≤4.75.

[0056] Specifically, a can be, but is not limited to, 3.75, 4, 4.25, 4.5, 4.75, etc., and no specific limitation is made here. Taking the interval between the first inner wall 12 and the second inner wall 13 at the channel section 141 as 4 mm as an example, correspondingly, the depth of the channel section 141 is 17 mm. At a width of 4 mm, if the depth of the mist outlet channel 14 is too low, the outflow is not straight enough, and the inclination angle of the emerging mist droplets is relatively large. However, increasing its depth to 17 mm can alleviate the inclination degree of the mist output to a certain extent.

[0057] In this way, the depth and width of the channel section 141 can be well matched, taking into account both the mist output speed and the smoothness of the mist output. The channel section 141 with sufficient depth can help alleviate the inclination degree of the mist output.

[0058] In some embodiments, the guiding part 30 has a guiding surface, the guiding surface has an inlet end and an outlet end, the inlet end is communicated with the mist outlet channel 14, the outlet end is communicated with the mist outlet 15, and the plane or tangent plane where the outlet end is located intersects or is parallel to the horizontal plane obliquely.

[0059] It can be understood that the inlet end of the guiding surface is the inlet end of the mist flow, the outlet end is the outlet end of the mist flow, the mist flow in the mist outlet channel 14 flows from the inlet end to the guiding surface and flows out of the guiding surface from the outlet end, and then mists out through the mist outlet 15.

[0060] The guiding surface can be an arc surface, a plane or a combined surface. Among them, when the guiding surface is a plane at the outlet end, the plane where the outlet end is located intersects or is parallel to the horizontal plane obliquely. When the guiding surface is an arc surface at the outlet end, the tangent plane of the outlet end intersects or is parallel to the horizontal plane obliquely. In short, the plane or tangent plane where the outlet end is located is not perpendicular to the horizontal plane.

[0061] In this way, the mist flow flowing out from the outlet end can obtain a speed that intersects or is parallel to the horizontal plane obliquely.

[0062] In some embodiments, the guiding part 30 is a guiding rib, the guiding rib extends from the first inner wall 12 towards the second inner wall 13, and the surface facing the mist outlet channel 14 is formed as a guiding surface. Specifically, the guiding rib is a T-rib structure extending along the mist outlet end face 11.

[0063] In this way, the structure of the guiding part 30 is simple, and it can effectively weaken the wall attachment effect of the mist flow and improve the mist flow direction.

[0064] Further, the extending length of the guiding rib towards the second inner wall 13 is L, and b·D ≤ L ≤ c·D, where 0.2 ≤ b ≤ 0.3 and 0.28 ≤ c ≤ 0.38. In addition, the thickness T of the guiding rib satisfies 1 mm ≤ T ≤ 1.5 mm.

[0065] Understandably, b < c. Specifically, b can be, but is not limited to, 0.2, 0.23, 0.25, 0.28, 0.3, etc., and c can be, but is not limited to, 0.28, 0.3, 0.33, 0.36, 0.38, etc.

[0066] In this way, while effectively improving the flow direction of the mist outlet airflow, the flow guiding ribs will not generate excessive resistance and reduce the mist output. In addition, the flow guiding ribs can also have good structural strength.

[0067] Alternatively, the extension length of the flow guiding rib towards the second inner wall 13 is L, and the height difference between the top ends of the first inner wall 12 and the second inner wall 13 at the position where the flow guiding rib is located is ΔH, then L is positively correlated with ΔH.

[0068] In this way, for the position where the mist outlet 15 is parallel to the horizontal plane, the height difference between the top ends of the first inner wall 12 and the second inner wall 13 here remains unchanged and can be a fixed value. For the position where the mist outlet 15 extends in a direction intersecting the horizontal plane, the height difference between the top ends of the first inner wall 12 and the second inner wall 13 will gradually change. Correspondingly, the extension length of the flow guiding rib also gradually changes to achieve a smooth transition.

[0069] In other words, the flow guiding rib includes an intermediate section 31 and two transition sections 32. The two transition sections 32 are connected to both sides of the intermediate section 31. The extension length of the intermediate section 31 is L, and the extension lengths of the two transition sections 32 on both sides gradually change from L at the connection with the intermediate section 31 to 0.

[0070] Please refer to Figure 4 and Figure 5 , in some embodiments, the mist outlet structure 100 further includes a support plate 50 and a top bracket 70. The support plate 50 and the top bracket 70 together define an installation space, and the mist outlet top cover 10 is installed in the installation space.

[0071] Among them, the support plate 50 is located at the bottom of the mist outlet top cover 10 and supports the mist outlet top cover 10 from the bottom side. The top bracket 70 is located on the periphery of the mist outlet top cover 10 and conforms to the shape of the mist outlet top cover 10 to limit and support the mist outlet top cover 10 on the periphery.

[0072] In this way, the mist outlet top cover 10 can be installed through the support plate 50 and the top bracket 70 and is supported by both of them.

[0073] The above-mentioned mist outlet structure 100 includes a mist outlet top cover 10, a diversion part 30, a support plate 50, and a top bracket 70. Among them, the mist outlet top cover 10 is formed with a mist outlet channel 14. The channel section 141 of the mist outlet channel 14 is a long and narrow channel, which plays a role in accelerating the water mist and adjusting the flow direction. The water mist flows out of the humidification component 200 through the mist outlet channel 14 and the mist outlet 15 formed by the mist outlet channel 14 at the mist outlet end face 11. The mist outlet top cover 10 is mainly composed of an inner part 16 and an outer part 17. An annular runway-shaped mist outlet 15 is formed at an interval between the inner part 16 and the outer part 17. The inner part 16 and the outer part 17 are connected through a diversion grille 18 in the mist outlet 15. The inclination angle of the mist outlet top cover 10 relative to the horizontal plane is α, satisfying 15° ≤ α ≤ 24°. The width D of the mist outlet channel 14 should not be too large, about 4 mm, to ensure a good mist outlet speed. The depth of the mist outlet channel 14 is H, satisfying H ≥ 4.25D, to ensure that the outflow direction of the water mist is as straight as possible. The mist outlet 15 can be divided into a front-side mist outlet 151 and a rear-side mist outlet 152. A diversion rib is provided on the front side of the top of the inner part 16. The thickness T of the diversion rib satisfies 1 mm ≤ T ≤ 1.5 mm, and its extension length L satisfies 0.25D ≤ L ≤ 0.33D. The diversion rib smoothly transitions between the front-side mist outlet 151 and the rear-side mist outlet 152. On the one hand, the diversion rib T changes the mist outlet flow direction of the front-side mist outlet 151, making the front-side mist outlet air flow not prone to tilt backward. On the other hand, it reduces the size of the front-side mist outlet 151, thereby increasing the flow rate of the front-side mist outlet air flow, and finally making the overall mist outlet direction straighten.

[0074] Please also refer to Figure 6 , this application also provides a humidification component 200, including the above-mentioned mist outlet structure 100. The humidification component 200 can be installed on a skirting heater, and together form a humidifying skirting heater.
