Description

The present invention relates to the field of humidifiers, and in particular to mist-free humidifiers using a water sprinkler system.

As consumption levels rise, humidifiers have become an essential electrical appliance in the home, and consumer demands are becoming ever higher. Many mist-free humidifiers currently on the market achieve mist-free humidification by immersing the filter directly in water. However, with this type of humidifier, the entire filter cannot be moistened unless the water level in the humidifier is high, and the humidifying effect is inevitably underestimated. In addition, uneven wetting of the filter occurs, which leads to bacteria breeding at the boundary between wet and dry parts of the filter, causing the filter to yellow and shortening its lifespan. For this reason, a new trend is to use a pump to spray water on the filter.

In conventional systems like this, the filter is placed inside the filter holder, a groove is provided on the top of the filter holder, and a holder guide column is provided on the side of the filter holder. Furthermore, a pump is used to pass water through the holder guide column and guide it to the groove on the top of the filter holder, and the water inside the groove moistens the filter, thereby achieving mist-free humidification.

However, when water enters the groove from the outlet of the holder's guide column, much of the water collides with the upper wall of the filter holder's top cover, causing a downward flow, significantly weakening the water flow rate. At the same time, because the water flow must be redirected to flow in both clockwise and counterclockwise directions, much of the water collides with the inner walls of the groove, causing a backflow in the opposite direction. In other words, the closer to the outlet the water flow becomes, the more turbulent it becomes and collides with the side walls of the groove, so the water does not reach the farthest end of the groove, or does not reach the farthest end of the groove sufficiently, which means the groove cannot be filled evenly with water, resulting in uneven wetting of the filter.

The object of the present invention is to provide a spray-type mist-free humidifier that solves the problem that, in the conventional configuration in which water is sprayed onto a filter using a pump, when water enters a groove from the water outlet of the holder flow guide column, the water flow becomes turbulent at the location of the outlet, making it impossible to fill the groove evenly with water, resulting in uneven wetting of the filter.

Also, although the embodiments described below have various structures, they can also have other structures that will become apparent upon understanding the disclosed content of the present invention.

By providing a spray-type mist-free humidifier, the present invention solves the problem that in the conventional configuration where a pump is used to spray water onto a filter, when water from the water outlet of the holder flow guide column enters the groove, the water flow becomes turbulent at the location of the outlet, making it impossible to fill the groove evenly with water, resulting in uneven wetting of the filter.

As consumption levels rise, humidifiers have become an essential electrical appliance in the home, and consumer demands are becoming ever higher. Many mist-free humidifiers currently on the market achieve mist-free humidification by immersing the filter directly in water. However, with this type of humidifier, the entire filter cannot be moistened unless the water level in the humidifier is high, and the humidifying effect is inevitably underestimated. In addition, uneven wetting of the filter occurs, which leads to bacteria breeding at the boundary between wet and dry parts of the filter, causing the filter to yellow and shortening its lifespan. For this reason, a new trend is to use a pump to spray water on the filter.

In conventional systems like this, the filter is placed inside the filter holder, a groove is provided on the top of the filter holder, and a holder guide column is provided on the side of the filter holder. Furthermore, a pump is used to pass water through the holder guide column and guide it to the groove on the top of the filter holder, and the water inside the groove moistens the filter, thereby achieving mist-free humidification.

However, when water enters the groove from the outlet of the holder's guide column, much of the water collides with the upper wall of the filter holder top cover, causing a downward flow, significantly weakening the water flow rate. At the same time, because the water flow must be redirected to flow in both clockwise and counterclockwise directions, much of the water collides with the inner wall of the groove, causing a backflow in the opposite direction. In other words, the closer to the outlet the water flow becomes, the more turbulent it becomes and collides with the side walls of the groove, so the water does not reach the farthest end of the groove, or does not reach the farthest end of the groove sufficiently, which means the groove cannot be filled evenly with water, resulting in uneven wetting of the filter.

In view of this, in the sprinkler-type mist-free humidifier of the embodiment of the present application, the filter 200 is installed on the inside of the filter holder 100, and when the sprinkler-type mist-free humidifier is in use, the groove 101 is located above the filter 200 and is used to moisten the filter 200, the tank 300 is installed below the filter holder 100, and a holder guide column 102 is installed on the inside of the filter holder 100, so that the water inside the tank 300 can flow into the groove 101 via the holder guide column 102, and the groove 101 includes a bottom surface, and when the position of the water outlet located at the top of the holder guide column 102 on the bottom surface is defined as the nearest end, and the position opposite the nearest end as the farthest end, the bottom surface is divided into two parts by a straight line passing through the nearest end and the farthest end, a first guide member 700 is installed inside the holder guide column 102, a first water intake 701 is installed at the bottom of the first guide member 700, and two first water outlets 702 are installed at the top of the first guide member 700, and the two first water outlets 702 divide the water flow into two parts and guide it.

In the embodiment of the present application, as shown in Figs. 1 to 5 and 12, the groove 101 may be annular, and may include a first annular wall, a second annular wall, and a bottom surface (here, as shown in Fig. 9, when the difference between the inner diameter ΦA and the outer diameter ΦB of the groove 101 is included in 6 to 8 mm, the effect of the water flow is further enhanced.), and a plurality of nozzles 103 are installed at the bottom of the groove 101, and the plurality of nozzles 103 are installed along the circumferential direction of the groove 101, and the plurality of nozzles 103 are in contact with the top of the filter 200 (here, the filter 200 may be annular, and may also be shaped to avoid the holder guide column 102.), and the water inside the groove 101 is dripped through the nozzles 103 to wet the filter 200. The arrangement and specific structure of the plurality of nozzles 103 will be described in detail below.

In the embodiment of the present application, when the sprinkler-type mist-free humidifier is started, the pump assembly 500 operates, and the water inside the tank 300 flows into the groove 101 via the holder guide pole 102 and wets the filter 200. In this case, when the fan rotates, the air passing through the filter 200 is moistened, thereby achieving the effect of mist-free humidification. Here, when the water flow reaches the top of the holder guide pole 102 and passes through the first guide member 700, the first guide member 700 has a sufficient guiding effect (i.e., it is more favorable for changing the direction and accelerating the water flow). That is, when water enters through the first water intake 701 at the bottom of the first diversion member 700, the two first water outlets 702 installed at the top of the first diversion member 700 divide the water flow into two and guide it, one flowing clockwise along the groove 101 and the other flowing counterclockwise along the groove 101, greatly reducing the collision of the water flow, so that when the water reaches the farthest end, it fills the groove 101 evenly and ensures even wetting of the filter 200.

Specifically, as shown in FIG. 10, the two first water outlets 702 at the top of the first diversion member 700 are open to both sides, and may have a "T"-shaped cross section. The two first water outlets 702 penetrate the second annular wall (i.e., the outer annular wall) and are located inside the groove 101, thereby dividing the water flow into two and directing it.

For example, the first guide member 700 includes a main body and a guide portion, the main body (main body pipe) is installed inside the holder guide column 102 with a seal, the guide portion is connected to the top of the main body, and a first water outlet is installed at each end of the guide portion, and the guide portion can be located inside the groove 101 through the second annular wall (i.e., the outer annular wall), where the guide portion can be a pipe with a relatively small diameter and installed perpendicular to the main body, and the main body can divide the guide portion into two parts evenly. That is, a water hole communicating between the main body and the guide portion is located at the middle position of the guide portion, and the two parts of the guide portion each divide the water flow equally into two and guide it.

Figure 8 shows the holder guide column 102 on the side of the filter holder 100 (i.e., a schematic diagram of the water flow when the first guide member 700 is not attached), in which the direction indicated by the arrow A represents a backflow with respect to the desired flow, and the direction indicated by the other arrow represents the desired flow. From this, when the water that has passed through the second guide member 600 reaches the top of the holder guide column 102, there is no guidance by the first guide member 700, and much of it flows back, so the water flow speed is greatly weakened, and at the same time, the water flow is changed in direction and flows in a clockwise and counterclockwise direction. Therefore, without the guidance of the first guide member 700, a backflow would still occur, and the direction of the water flow becomes more disturbed the closer it is to the water outlet, and it collides with the side wall of the groove 101, so the water cannot reach the farthest end, or cannot reach the farthest end sufficiently, which causes the water to not fill the groove 101 evenly, causing uneven wetting of the filter 200.

Figure 9 shows a schematic diagram of the water flow when the first guide member 700 is attached to the filter holder 100. By attaching the first guide member 700, when the water reaches the top of the holder guide column 102, a sufficient guide action is achieved, and the water flows clockwise and counterclockwise along the groove 101 through the first guide member 700, so that the water flow is greatly reduced from colliding with the side wall of the groove 101. This allows the water to fill the groove 101 sufficiently and uniformly.

Also, as shown in FIG. 2, the mistless humidifier can include a filter holder top cover 800 for sealing the top of the groove 101.

In addition, in the conventional method of spraying water onto a filter with a pump, the pump guides water into a groove at the top of the filter, and the filter is then wetted with the water in the groove, achieving mist-free humidification. However, in the above method of spraying water onto a filter with a pump, the water pressure of the pump is often insufficient, preventing the water from reaching the top of the filter smoothly and preventing the filter from being wetted evenly. Also, if the operating voltage of the pump is set too high to ensure water flow, abnormal vibration noises can occur.

In view of this, in the embodiment of the present application, as shown in Figures 1 to 5, the sprinkler-type mist-free humidifier further includes a second guide member 600, a tank guide pole 301 is installed on the inner side of the tank 300, the water in the tank can flow from the tank guide pole 301 through the holder guide pole 102 into the groove 101, the second guide member 600 connects the tank guide pole and the holder guide pole 102, a second water intake port is opened at the bottom of the second guide member 600, and a second water outlet port 603 is opened at the side of the second guide member 600, and the cross-sectional area of the second water intake port is larger than the cross-sectional area of the second water outlet port.

In the embodiment of the present application, when the sprinkler-type mist-free humidifier is started, the pump assembly 500 operates, and the water inside the tank 300 flows from the tank guide pole 301 through the holder guide pole 102 into the groove 101, and drips through the nozzle 103 to wet the filter 200. In this case, when the fan rotates, the air passing through the filter 200 becomes moist, thereby achieving the effect of mist-free humidification. Here, when the water inside the tank 300 passes through the second guide member 600, the water enters from the second water intake port at the bottom of the second guide member 600 and flows out from the two direction change ports (two second water outlet ports 603 located on the sides) of the second guide member 600. Here, the water flow rate and pressure are increased to ensure that the water flows smoothly upward, and since the cross-sectional area of the second water intake is larger than the cross-sectional area of any second water outlet 603, it is more favorable to change the direction and accelerate the water flow, allowing the water to reach the top of the filter 200 smoothly and wet the filter 200 evenly, achieving mist-free humidification (as shown in FIG. 4, the water is pulled up to the inside of the groove 101 by the tank guide pole 301 and the holder guide pole 102, and drips through the nozzle 103 to wet the filter 200).

For example, as shown in FIG. 7, a first interference structure 601 and a second interference structure 602 are provided on the outer edge of the second diversion member 600, the first interference structure 601 is located above the second interference structure 602, the first interference structure 601 is interference-fitted with the holder diversion column 102, and the second interference structure 602 is interference-fitted with the tank diversion column 301 (a 0.3-1.0 mm interference fit is made with soft rubber to ensure sealing).

In the embodiment of the present application, as shown in FIG. 6 (arrows indicate the direction of water flow), the second guide member 600 (three-way water guide pipe) can be designed in a tower-type like a well, with the second water intake being large and the second water outlet 603 being small, that is, the diameter of the second guide member 600 gradually decreases from the bottom to the top. Here, the two second water outlets 603 can be installed opposite each other, and the cross-sectional areas of the two second water outlets 603 can be the same, and preferably, when the ratio of the cross-sectional area of the second water intake to the cross-sectional area of any one of the second water outlets 603 is 4:1 to 2:1, it is more favorable for redirecting and accelerating the water flow.

Furthermore, in order to fully ensure that the water guided from the holder guide column 102 flows to the farthest end of the groove 101, it is necessary to ensure that there is a certain height difference between the farthest end and the nearest end. Specifically, as shown in Figures 11 and 12, the groove 101 can include a first annular wall, a second annular wall, and a bottom surface (here, as shown in Figure 9, when the difference between the inner diameter ΦA and the outer diameter ΦB of the groove 101 is between 6 and 8 mm, that is, when the difference between the diameter of the first annular wall of the groove 101 and the diameter of the second annular wall is between 6 and 8 mm, the effect of the water flow is further enhanced.) The bottom surface is provided with a slope, and here, the position of the water outlet located at the top of the holder guide column 102 on the bottom surface is defined as the nearest end, and the position opposite the nearest end is defined as the farthest end, and the bottom surface is divided into two parts by a straight line where the nearest end and the farthest end are located, and each part gradually slopes from the nearest end to the farthest end.

As shown in FIG. 11, the height difference ΔH may be between 3 and 5 mm (FIG. 11 shows the height difference where the nozzles 103 located at the nearest and furthest ends are affected by the gradient), thereby ensuring that water can flow from the nearest end to the furthest end of the groove 101, and that the water depth at each nozzle 103 position is greater than 2 mm, ensuring that water drips from each nozzle 103 (for example, the shape of the nozzle 103 is a diamond). In addition, the water flow interface of the filter holder 100 is designed to be arc-shaped, so that it is easier to make the water flow from the nearest end to the furthest end compared to other straight shapes. In addition, the height of the nozzle 103 is between 2 and 5 mm, and depending on the distance between the nozzle 103 and the nearest end, when the distance is the shortest, the flow rate is the fastest and the height of the nozzle 103 is the lowest, and when the distance is the furthest, the flow rate is the slowest and the height of the nozzle 103 is the highest, ensuring that the water does not overflow but flows smoothly from the nozzle 103 to the filter 200 and is able to wet the filter 200.

In addition, in an embodiment of the present application, as shown in Figures 13 to 16, the sprinkler-type mist-free humidifier may further include an annular base 900, the base 900 is sloped, and a plurality of flow-guiding ribs 902 are provided on the upper surface of the base 900, the plurality of flow-guiding ribs 902 are provided along the circumferential direction of the annular base 900, the plurality of flow-guiding ribs 902 contact the bottom of the filter 200, a dam wall 901 is provided on the inner edge of the base 900, and an annular gap exists between the outer edge of the base 900 and the inner wall of the tank 300. The bottom of the filter holder 100 is connected to the upper surface of the outer edge of the base 900, i.e., connected to the outside of the ends of the flow guide ribs 902, and a plurality of holes 104 are provided along the outer edge of the bottom of the filter holder 100, and any two adjacent flow guide ribs 902 are defined as a flow guide pair, and the plurality of flow guide pairs correspond one-to-one with the plurality of holes 104 (one flow guide pair can correspond to one or more holes 104), and wastewater from the filter 200 can flow from the flow guide pair through the corresponding hole 104 to the annular gap.

Specifically, as shown in FIG. 14, the flow guide ribs 902 can be evenly distributed on the base 900 (the filter holder bottom cover), and the flow guide ribs 902 (each arranged at 15°-30°) and the holes 104 are in contact with the bottom of the filter 200. When excess water flows out of the filter 200, these evenly distributed flow guide ribs 902 guide the water flow diagonally downward, and ensure that the water flows merge into large droplets, and no dripping noise is generated. At the same time, as shown in FIG. 15, the bottom of the filter holder 100 is provided with evenly distributed holes 104, which may be multiple recesses installed along the outer edge.

Here, as shown in FIG. 16, the outer edge of the base 900 can be inserted into a part of the tank 300, and the gap with the inner wall of the tank 300 can be 0.5 mm or less. The water flow is guided by the base 900, flows out of the evenly distributed holes 104, and flows along the inside of the tank 300, not only ensuring the return of water, but also ensuring that no dripping noise is generated.

In the embodiment of the present application, when using a sprinkler-type mistless humidifier, first put water into the tank 300 and operate the pump assembly 500 (here, as shown in FIG. 2, the pump assembly 500 can include a water discharge module 501, a water intake module 502, a water discharge port gasket 503, and a water intake port gasket 504). The water inside the tank 300 is pumped up by the pump, enters the water intake module 502, flows out of the water discharge module 501, and flows upward along the tank guide column 301. A first water pressure strengthening structure, i.e., a second guide member 600 (lower three-way water guide pipe) is attached above the tank guide column 301, and after the water pressure is increased, it continues to flow upward through the holder water guide column 102. A second water pressure reinforcement structure, i.e., a first guide member 700 (upper three-way water guide pipe) is attached to the top of the filter holder 100, and at this time, the flow direction of the water flow is changed, and the water is guided by the first guide member 700 to flow clockwise and counterclockwise, respectively. Several water leakage holes are distributed on the groove 101 of the filter holder 100, and the flowing water enters the nozzle 103 through the water leakage holes and drips downward to moisten the filter 200. In this case, when the fan rotates (here, the motor assembly 400 on the top of the filter holder 100 can include a motor 401 and a blade 402), the air passing through the filter 200 is moistened, thereby achieving the effect of mist-free humidification.

In the embodiment of the present application, the water flow sent out by the pump is redirected twice to increase the water pressure through two "three-way water pipes", a reasonable height difference between the water intake and discharge surfaces, and the nozzle 103, ensuring that the filter 200 is evenly wetted and that the humidifier can achieve high-performance mist-free humidification at any water level. At the same time, the evenly distributed flow guide ribs 902 and holes 104 (water discharge ports) are installed at the bottom of the filter holder 100, allowing excess water from the filter to flow back to the tank, while also ensuring quiet operation.

In the embodiment of the sprinkler-type non-mist humidifier of the present application, a filter is installed on the inside of a filter holder, and when the sprinkler-type non-mist humidifier is in use, a groove is located above the filter and is used to moisten the filter, a tank is installed below the filter holder, and a holder guide column is installed on the inside of the filter holder, so that water inside the tank can flow into the groove via the holder guide column, the groove includes a bottom surface, and when the position of the water outlet located at the top of the holder guide column on the bottom surface is defined as the nearest end and the position opposite the nearest end as the farthest end, the bottom surface is divided into two parts by a straight line passing through the nearest end and the farthest end, a first guide member is installed inside the holder guide column, a first water intake is installed at the bottom of the first guide member, and two first water outlets are installed at the top of the first guide member, and the two first water outlets divide and guide the water flow into two parts.

In the embodiment of the present application, when the sprinkler-type mistless humidifier is started, the pump assembly operates, and the water inside the tank flows into the groove through the holder guide column and wets the filter. In this case, when the fan rotates, the air passing through the filter is moistened, thereby achieving the effect of mistless humidification. Here, when the water flow reaches the top of the holder guide column and passes through the first guide member, the first guide member has a sufficient guiding effect (i.e., it is more favorable for changing the direction and accelerating the water flow). That is, when the water enters from the first water intake at the bottom of the first guide member, the two first water outlets installed at the top of the first guide member divide the water flow into two and guide it, one flows clockwise along the groove and the other flows counterclockwise along the groove, greatly reducing the collision of the water flow, so that when the water reaches the farthest end, the groove is filled evenly, and the filter can be evenly wetted.

Finally, it should be explained that the above examples are merely specific embodiments of the present application, and are intended to explain the technical methods of the present application, but are not intended to limit the same, and the scope of protection of the present invention is not limited thereto. Although the present application has been described in detail with reference to the above examples, a technician familiar with the present technical field may make modifications or easily conceivable changes to the technical methods described in the above examples, or make equivalent substitutions for some of the technical features therein, within the technical scope disclosed in the present application, but it should be understood that these modifications, changes or substitutions do not deviate the essence of the corresponding technical methods from the spirit and scope of the technical methods in the examples of the present application, and are all covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
