Description

Technical Field

[0001] This application relates to the field of spray technology, and more particularly to a spray structure for use in humidifiers. Background Technology

[0002] Humidifiers, as a common household or commercial appliance, are mainly used to regulate air humidity and improve the indoor environment. Currently, most humidifiers on the market are spray-type humidifiers, which spray water onto the humidifying filter through spray nozzles to achieve the humidification effect.

[0003] However, most existing spray humidifiers use a design where the water flowing in from the inlet directly impacts the spray holes. This design leads to uneven water output from each spray hole, with excessive water output from the spray holes near the inlet and insufficient water output from the spray holes far from the inlet, resulting in uneven humidification of the humidifying filter. Utility Model Content

[0004] This application provides a spray structure for use in a humidifier to solve the technical problem of uneven water output from the spray holes in existing spray structures, which leads to uneven wetting of the humidifier filter.

[0005] This application provides a spray structure for use in a humidifier, including a spray component, a water collection tank on the spray component, and a water inlet at the bottom of the water collection tank;

[0006] The water collection tank has multiple spray holes on one of its side walls. The spray holes are evenly distributed along the extension direction of the water collection tank. There is a preset height between the spray holes and the bottom of the water collection tank so that the water flow accumulates in the water collection tank to the preset height before being sprayed out through the spray holes.

[0007] In one possible implementation, one sidewall of the water collection tank protrudes towards the other sidewall to form a spray boss, and the spray holes are provided on the spray boss.

[0008] In one possible implementation, the orifice of the spray hole near the upper surface of the spray boss has an inclined guide surface.

[0009] In one possible implementation, the edge of the spray boss adjacent to the bottom of the water collection tank is formed as a smooth curved surface.

[0010] In one possible implementation, the water collection tank has a U-shaped cross-section.

[0011] In one possible implementation, the outlet end of the inlet is provided with a vertical baffle, which evenly divides the outlet end to form two outlet channels.

[0012] In one possible implementation, a transverse baffle is provided at the end of the vertical baffle away from the water collection tank. The axial direction of the transverse baffle is perpendicular to the axial direction of the vertical baffle, and is used to guide the vertical water flow to the water outlet channels on both sides.

[0013] In one possible implementation, the spray element has a limiting groove on the side opposite to the water collection tank, and the water outlet direction of the spray hole is towards the limiting groove.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] This application provides a spray structure for a humidifier. Water enters the water collection tank through an inlet at the bottom and accumulates, causing the water level to gradually rise. When the water level reaches a preset height, a stable water pressure is formed in the tank, and the water is sprayed out from multiple spray holes evenly distributed on the sidewalls of the tank under pressure. Understandably, the multiple spray holes are evenly distributed, and the preset height ensures consistent water pressure at each spray hole. According to fluid mechanics principles, under the same water pressure, the water output from each spray hole is consistent, thus ensuring that the humidifier filter is evenly wetted.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0027] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the spray structure applied to the humidifier during use or operation, other than those depicted in the figure. For example, if the spray structure applied to the humidifier in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The spray structure applied to the humidifier may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0028] To address the technical problem of uneven water output from the spray nozzles in existing spray structures, which leads to uneven wetting of the humidifying filter, this application provides a spray structure for use in humidifiers.

[0029] Figures 1 to 4 A spray structure for a humidifier provided in this application embodiment includes a spray component 1, a water collection tank 101 on the spray component 1, and a water inlet 102 at the bottom of the water collection tank 101.

[0030] A plurality of spray holes 103 are provided on one side wall of the water collection tank 101. The spray holes 103 are evenly distributed along the extension direction of the water collection tank 101. There is a preset height between the spray holes 103 and the bottom of the water collection tank 101 so that the water flow accumulates in the water collection tank 101 to the preset height before being sprayed out through the spray holes 103.

[0031] In the above technical solution, the water inside the humidifier flows into the water collection tank 101 from the water inlet 102 at the bottom of the tank. Since there is a preset height between the spray hole 103 and the bottom of the water collection tank 101, the water will not spray out from the spray hole 103 immediately, but will gradually accumulate in the water collection tank 101.

[0032] When the water level rises to the preset height, a stable water pressure is formed in the water collection tank 101. Because the spray holes 103 are evenly distributed on one side wall of the water collection tank 101 and the distribution direction is parallel to the extension direction of the water collection tank 101, under the action of stable water pressure, the water will be evenly sprayed out from each spray hole 103, forming a uniform water mist in the spraying area.

[0033] Understandably, multiple spray holes 103 are evenly distributed and parallel to the extension direction of the water collection tank 101. Under the premise that the water pressure at each spray hole 103 is consistent at the preset height, according to the principle of fluid mechanics, the water output of each spray hole 103 is the same under the same water pressure and spray hole structure, thereby ensuring that the sprayed water mist is evenly distributed in space.

[0034] When a humidifier is working, the even mist effectively humidifies the entire humidification area, preventing over- or under-humidification in certain areas and improving humidification performance and user experience. For example, in an indoor environment, it can prevent bacteria growth in some areas due to dampness, and also prevent discomfort caused by dryness in other areas.

[0035] Please refer to Figure 1 and Figure 4In one possible implementation, one sidewall of the water collection tank 101 protrudes towards the other sidewall to form a spray boss 104, and spray holes 103 are provided on the spray boss 104. When water enters the water collection tank 101 from the inlet 102 at the bottom of the tank, it will continuously accumulate in the water collection tank 101. Due to the presence of the spray boss 104, after the water accumulates to a certain height in the water collection tank 101, it flows along the sidewall towards the spray boss 104 and is then sprayed out from the spray holes 103.

[0036] Please refer to Figure 4 In one possible implementation, the spray hole 103 has an inclined guide surface 105 near the upper surface of the spray boss 104. When water accumulates to a certain height in the water collection tank 101 and flows towards the spray hole 103 under pressure, it first contacts the guide surface 105 at the opening of the spray hole 103. Since the guide surface 105 extends downward at an incline, the water flow is subjected to a downward component force. This component force changes the original trend of the water flow, guiding the water flow downward along the inclined direction of the guide surface 105.

[0037] For example, if the tilt angle of the guide surface 105 is large, the downward component of the force on the water flow will also increase accordingly, causing the water flow to spray downwards at a steeper angle. During the spraying process along the guide surface 105, the downward tilting characteristic of the guide surface 105 also affects the spray pattern and velocity of the water flow. Guided by the guide surface 105, the water flow forms a stream with a certain directionality and concentration. Simultaneously, due to the effect of the guide surface 105, the water flow may acquire a certain initial velocity upon ejection. The magnitude of this initial velocity is related to factors such as the tilt angle of the guide surface and the water pressure. A larger initial velocity allows the water flow to be sprayed further, thereby expanding the coverage area of ​​the water mist.

[0038] In one possible implementation, the edge of the spray boss 104 adjacent to the bottom of the water collection tank 101 is formed as a smooth curved surface. When water enters the water collection tank 101 from the inlet 102, it accumulates at the bottom of the tank and begins to flow. Because the edge of the spray boss 104 adjacent to the bottom of the tank is a smooth curved surface, the water flows along the shape of the curved surface when it comes into contact with it. The smoothness of the curved surface ensures that the water flow is not significantly hindered or affected by turbulence during the flow process, thus allowing it to flow more smoothly towards the spray boss 104.

[0039] For example, the water flow will gradually rise along the curved surface, like following a smooth track, and eventually reach the area where the spray hole 103 is located. As the water flows along the smooth curved surface, the pressure and velocity of the water will change due to the shape and angle of inclination of the surface. This change helps to distribute the water more evenly to each spray hole 103, ensuring the stability of the spraying effect.

[0040] In one possible implementation, the water collection tank 101 has a U-shaped cross-section. When water enters the water collection tank 101 from the inlet, the U-shaped structure causes the water to gradually accumulate at the bottom. The U-shaped bottom provides a platform for water accumulation, allowing the water to be evenly distributed within the water collection tank 101. As water is continuously injected, the water level gradually rises until it reaches a certain height, at which point the water pressure also increases accordingly. When the water level rises to a certain level, the water flows along the sidewall of the water collection tank 101 under pressure towards the spray boss 104. The U-shaped sidewall guides the water flow, making it flow more orderly. Upon reaching the spray boss 104, the water is sprayed out through the spray holes 103, forming a water mist to achieve the humidification function.

[0041] Please refer to Figure 4 In one possible implementation, a vertical baffle 106 is provided at the outlet end of the inlet 102, which evenly divides the outlet end to form two outlet channels. When water flows in from the inlet 102, due to the dividing effect of the vertical baffle 106, the water flow is evenly divided into two parts, which enter the collection tank 101 through the two outlet channels respectively. As water continues to flow in, the water level in the collection tank 101 gradually rises. When the water level reaches the preset height between the spray hole 103 and the bottom of the tank, water will spray out from the spray holes 103 evenly distributed on the side wall of the collection tank 101. It can be understood that the vertical baffle 106 evenly divides the outlet end of the inlet 102 into two outlet channels, so that the water flow can enter the collection tank 101 more evenly. Compared to single-channel water inlet, this method avoids concentrated water flow impacting a certain area of ​​the water collection tank 101, making the water level rise in the water collection tank 101 more stable. This provides a good foundation for the subsequent water flow to be sprayed evenly from each spray hole 103, further improving the uniformity of spraying.

[0042] At the same time, the two water outlet channels formed by uniform separation are equivalent to increasing the flow area of ​​water inlet. Under the same water inlet pressure, more water can enter the water collection tank 101 at the same time, which improves the water inlet efficiency and speeds up the rise of the water level in the water collection tank 101, thereby reaching the water level required for spraying more quickly, so that the humidifier can enter the spraying working state more quickly.

[0043] In one possible implementation, a transverse baffle 107 is provided at the end of the vertical baffle 106 away from the water collection tank 101. The axial direction of the transverse baffle 107 is perpendicular to the axial direction of the vertical baffle 106, and it is used to guide the vertical water flow to the outlet channels on both sides. It is understood that the transverse baffle 107 and the vertical baffle 106 are arranged in a T-shape. In use, the end of the vertical baffle 106 can be selectively connected to or not connected to the transverse baffle 107. When water flows vertically from the inlet 102, the transverse baffle 107 functions to block and guide this vertical water flow to both sides of the vertical baffle 106. Subsequently, the water flows into the two outlet channels separated by the vertical baffle 106, and finally flows into the water collection tank 101. When the water level in the water collection tank 101 rises to a preset height between the spray hole 103 and the bottom of the tank, water will spray out from the spray hole 103.

[0044] In one possible implementation, the spray element 1 has a limiting groove 108 on the side opposite to the water collection tank 101, and the water outlet direction of the spray hole 103 faces the limiting groove 108. In use, one end of the humidifying filter (not shown in the figures) is inserted into the limiting groove 108. Since the water outlet direction of the spray hole 103 faces the limiting groove 108, after one end of the humidifying filter is inserted into the limiting groove 108, the water flow from the spray hole 103 can be evenly sprayed onto the humidifying filter, allowing the top of the humidifying filter to be more evenly wetted. Under the action of gravity, the water flow will wet the entire humidifying filter from top to bottom, thereby solving the problem of uneven humidity distribution in existing humidifier filters and improving the humidification effect.

[0045] It should be noted that in this application, the water collection tank 101 forms a rectangular structure around the circumference of the spray element 1. This design means that humidifying filters are provided on all four sides of the spray element 1. Traditional humidifiers may only have humidifying filters on some sides, while with this structure, humidifying filters are provided on all four sides of the spray element 1, significantly increasing the contact area. For example, if the spray element 1 is cubic in shape, with a traditional single-sided or double-sided filter, the contact area between the water mist and the filter is only the area of ​​one or two sides of the cube; however, with filters on all four sides, the contact area becomes twice as large (if comparing only double-sided) or four times as large (if comparing single-sided), allowing the water mist to interact more fully with the water-absorbing material in the filter, enabling more moisture to be absorbed and diffused by the filter.

[0046] Understandably, the four-sided humidifying filter design allows the water mist to diffuse evenly in all directions. Previously, due to incomplete humidifying filter placement, the water mist might diffuse primarily in one direction, leading to localized over-humidification while other areas were under-humidified. Now, after the water mist is sprayed from spray unit 1, it is simultaneously sprayed in four directions and comes into contact with the humidifying filter. Then, under the action of the humidifying filter, it is evenly distributed into the surrounding environment, improving the uniformity and efficiency of humidification throughout the space.
