Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and more specifically, to a water pressure balancing module and a humidification device. Background Technology

[0002] Humidifiers typically require a water source to provide a continuous water supply. Inlet water pressure is one of the key factors affecting the normal operation of a humidifier.

[0003] In existing technologies, the large pressure fluctuations in the water supply system can lead to unstable inlet water pressure in humidifiers. When the inlet water pressure is too high, it can easily damage the internal structure of the humidifier, thus shortening its service life; while when the inlet water pressure is too low, the water flow rate will be insufficient, which will affect the moisture permeability and humidification effect, failing to meet the user's humidity regulation needs.

The guide tube is fixed and connected to the liquid inlet end. The guide tube has a guide hole for discharging liquid from the guide tube. The adjusting tube is sleeved around the outer periphery of the guide tube and can move relative to the guide tube so that the adjusting tube can cover or expose the guide hole. Furthermore, a flow gap for liquid to flow is provided between the adjusting tube and the guide tube. One end of the elastic element is connected to the end of the adjusting tube away from the liquid inlet end, and the other end of the elastic element is fixed.

[0006] In an optional embodiment, the central axes of the guide tube, the regulating tube, and the elastic element are located on the same straight line.

[0007] In an optional embodiment, the guide hole includes a first guide hole and a second guide hole. The first guide hole is opened at the end of the guide tube facing the elastic member, and the second guide hole is a plurality of holes opened on the side wall of the guide tube and spaced apart along the guide tube.

[0008] In an optional embodiment, the regulating pipe includes a first blocking wall and a second blocking wall. The first blocking wall faces the first guide hole and blocks the liquid discharged from the first guide hole. The second blocking wall is a cylindrical wall sleeved on the outer periphery of the guide pipe.

[0009] In an optional embodiment, the second barrier wall is provided with a one-way hole, which opens a passage from the outside of the second barrier wall toward the flow gap.

[0010] In an optional embodiment, a waterproof adhesive is provided between the guide tube and the regulating tube, and the waterproof adhesive is provided at the end of the regulating tube near the liquid inlet end.

[0011] In an optional embodiment, the elastic element is a spring, a guide is provided at the end of the adjusting tube away from the guide tube, and the end of the adjusting tube away from the guide tube is sleeved on the guide. The guide, the adjusting tube and the guide tube are coaxially arranged, the spring is sleeved on the guide, one end of the spring is connected to the end of the adjusting tube away from the liquid inlet, and the other end of the spring is fixed.

[0012] In an optional embodiment, the water pressure balancing module further includes a drain end, and the pressure balancing component is also provided at the drain end.

[0013] Secondly, this utility model provides a humidification device, including the water pressure balance module described in any of the foregoing embodiments. The humidification device also includes a housing, and a flow channel communicating with the liquid inlet is provided inside the housing. Multiple baffles are also provided inside the flow channel, and the baffles are arranged in an array inside the housing.

[0014] In an optional embodiment, the housing is further provided with vent holes, and the inner wall of the housing where the vent holes are provided is also attached with a waterproof and breathable membrane for exhaust and humidification.

[0015] The beneficial effects of the water pressure balancing module and humidification device provided in this embodiment of the invention include: This utility model's water pressure balancing module includes an inlet end and a pressure balancing component. The pressure balancing component includes a guide pipe, a regulating pipe, and an elastic element. The guide pipe is fixed and connected to the inlet end. A guide hole is provided on the guide pipe. The guide hole is used to discharge liquid from the guide pipe. The regulating pipe is sleeved around the outer periphery of the guide pipe and can move relative to the guide pipe so that the regulating pipe can cover or expose the guide hole. Furthermore, a flow gap for liquid to flow is provided between the regulating pipe and the guide hole. One end of the elastic element is connected to the side of the regulating pipe away from the inlet end, and the other end of the elastic element is fixed. By setting the elastic element and the regulating pipe, when the regulating pipe is subjected to the discharge pressure from the guide hole, the regulating pipe moves away from the inlet end. When the water pressure at the inlet end is low, the pressure on the elastic element is low, the distance the regulating pipe moves away from the inlet end is small, the number of exposed guide holes is small, and the volume of water flowing in is small. With the water flow rate remaining constant, the small flow volume of water entering the flow channel results in a larger pressure, thereby making the water flow pressure at the guide hole greater than the water flow pressure at the inlet end. When the water pressure is high, the elastic element experiences greater pressure, causing the regulating pipe to move a greater distance away from the inlet end. This results in a larger number of exposed guide holes, effectively creating a larger pipe cross-sectional area. Consequently, a larger volume of water flows in simultaneously. With a constant water flow rate, the increased volume of water entering the channel leads to a decrease in pressure, making the water pressure at the guide holes lower than that at the inlet end. This invention achieves automatic balancing of the inlet water pressure, maintaining a constant water pressure in the channel, preventing damage to the internal structure of the humidifier, and ensuring optimal humidification performance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Please refer to Figures 1-3 This utility model provides a humidifier 100 for humidifying indoor air by introducing gas discharged from the evaporation of a high-temperature liquid. Specifically, the humidifier 100 includes a housing 10 and a water pressure balancing module. The water pressure balancing module is used to adjust the water inlet pressure of the housing 10.

[0026] Specifically, the water pressure balancing module includes an inlet end 11 and a pressure balancing component 20. The inlet end 11 is disposed on the housing 10 and is used to introduce high-temperature liquid into the housing 10. The pressure balancing component 20 includes a guide pipe 21, an adjusting pipe 22, and an elastic element 23. The guide pipe 21 is fixed and connected to the inlet end 11. The guide pipe 21 has a guide hole. The guide hole is used to discharge the liquid in the guide pipe 21. In this embodiment, the guide pipe 21, the adjusting pipe 22, and the elastic element 23 are all disposed inside the housing 10. The high-temperature liquid enters the guide pipe 21 from the inlet end 11 and then enters the housing 10 through the guide hole. The adjusting pipe 22 is sleeved on the outer periphery of the guide pipe 21 and can move relative to the guide pipe 21 so that the adjusting pipe 22 can cover or expose the guide hole. Furthermore, a flow gap 25 for liquid to flow is provided between the adjusting pipe 22 and the guide pipe 21. Understandably, the regulating pipe 22 covers or exposes the guide hole, and liquid is discharged from the guide hole. Under the action of water pressure, the regulating pipe 22 moves away from the liquid inlet end 11, thereby exposing more of the guide hole. One end of the elastic element 23 is connected to the end of the regulating pipe 22 away from the liquid inlet end 11, and the other end of the elastic element 23 is fixed. Understandably, the elastic element 23 is used to provide a force to the regulating pipe 22 toward the liquid inlet end 11 to balance the water flow pressure at the other end of the regulating pipe 22.

[0027] Understandably, the pressure balancing component 20 is used to balance the inlet water pressure of the humidification device 100, so that the inlet water pressure is maintained within a preset range. By setting the pressure balancing component 20 to change the inlet water flow rate, a constant internal pressure in the flow channel is maintained, thereby achieving a stable moisture permeation rate.

[0028] The guide pipe 21 is connected to the inlet end 11. Liquid enters the guide pipe 21 from the inlet end 11 and then enters the flow channel through the guide holes. In this embodiment, the regulating pipe 22 moves along the guide pipe 21, thereby changing the number of guide holes exposed on the guide pipe 21. When hot water flows out from the guide holes, the regulating pipe 22 moves away from the inlet end 11 under the action of water pressure, thereby exposing the guide holes. At this time, the elastic element 23 is squeezed. When the water pressure at the inlet end 11 is low, the pressure on the elastic element 23 is low, the distance the regulating pipe 22 moves away from the inlet end 11 is small, and the number of exposed guide holes is small. This is equivalent to a smaller pipe cross-sectional area, that is, a smaller volume of water flowing in at the same time. With the water flow rate remaining constant, the smaller volume of water flowing into the flow channel results in a larger pressure, thereby making the water flow pressure at the guide holes greater than the water flow pressure at the inlet end 11, so that the water flow pressure at the guide holes reaches the preset pressure. When the water pressure is high, the elastic element 23 experiences greater pressure, causing the regulating pipe 22 to move a greater distance away from the inlet end 11. This results in a larger number of exposed guide holes, equivalent to a larger pipe cross-sectional area, meaning a larger volume of water flows in simultaneously. With a constant water flow rate, the increased volume of water entering the channel reduces the pressure, causing the water pressure at the guide holes to be lower than the water pressure at the inlet end 11, thus achieving the preset pressure. In other words, when the pressure at the inlet end 11 is lower than the preset pressure, the pressure balancing component 20 increases the inlet pressure at the guide holes to reach the preset pressure; conversely, when the pressure at the inlet end 11 is higher than the preset pressure, the pressure balancing component 20 decreases the inlet pressure at the guide holes to reach the preset pressure. This achieves the effect of regulating the inlet pressure, maintaining a constant water flow pressure, and thereby controlling the moisture permeability of the humidification device 100 to remain stable.

[0029] Understandably, the aforementioned preset pressure can be changed by adjusting the stiffness coefficient of the elastic element 23. For example, increasing the stiffness coefficient of the elastic element 23 increases the force required to produce the same deformation, making the regulating tube 22 less likely to be pushed. Under a constant pressure at the inlet end 11, fewer guide holes are exposed, resulting in a higher preset pressure. Conversely, decreasing the stiffness coefficient of the elastic element 23 decreases the force required to produce the same deformation, making the regulating tube 22 easier to push. Under a constant pressure at the inlet end 11, more guide holes are exposed, resulting in a lower preset pressure.

[0030] Furthermore, in this embodiment, the central axes of the guide pipe 21, the regulating pipe 22, and the elastic element 23 are located on the same straight line. It is understood that by setting the central axes of the guide pipe 21 and the regulating pipe 22 to be collinear, it is convenient for the regulating pipe 22 to move along the central axis of the guide pipe 21. By setting the central axes of the regulating pipe 22 and the elastic element 23 to be collinear, it is convenient for the elastic force of the elastic element 23 on the regulating pipe 22 to be balanced with the pressure of the water flow on the regulating pipe 22.

[0031] Specifically, in this embodiment, the guide hole includes a first guide hole 211 and a second guide hole 212. The first guide hole 211 is formed at the end of the guide tube 21 facing the elastic member 23. The second guide hole 212 consists of a plurality of holes formed on the sidewall of the guide tube 21 and spaced apart along the guide tube 21. It can be understood that in this embodiment, the guide tube 21 includes a sidewall and an end plate away from the liquid inlet end 11, the first guide hole 211 is formed on the end plate away from the liquid inlet end 11, and the second guide hole 212 is formed on the sidewall.

[0032] Correspondingly, the regulating pipe 22 includes a first blocking wall 221 and a second blocking wall 222. The first blocking wall 221 is disposed facing the first guide hole 211 and blocks the liquid discharged from the first guide hole 211. The second blocking wall 222 is a cylindrical wall sleeved on the outer periphery of the guide pipe 21. Specifically, the first blocking wall 221 is disposed inside the regulating pipe 22, and the first blocking wall 221 is disposed corresponding to the end plate of the guide pipe 21 away from the liquid inlet 11. The second blocking wall 222 is a cylindrical wall surrounding the side wall of the guide pipe 21. It can be understood that the gap between the first blocking wall 221 and the end plate of the guide pipe 21 away from the liquid inlet 11, and the gap between the second blocking wall 222 and the side wall of the guide pipe 21 together form a flow gap 25. Liquid discharged from the guide hole enters the flow gap 25, impacting the first blocking wall 221 and the second blocking wall 222, thereby pushing the regulating pipe 22 to move away from the liquid inlet 11.

[0033] Furthermore, a waterproof sealant (not shown) is provided between the guide pipe 21 and the regulating pipe 22. The waterproof sealant is located at the end of the regulating pipe 22 near the liquid inlet 11. By providing the waterproof sealant, liquid is prevented from flowing out of the flow gap 25 when the water pressure is too low, thus preventing the water pressure in the flow gap 25 from being too low to push the regulating pipe 22 to move. At the same time, when the water pressure reaches a certain value, the water flow can break through the waterproof sealant to prevent excessive pressure from damaging the regulating pipe 22.

[0034] In this embodiment, a one-way hole (not shown) is provided on the second barrier wall 222. The one-way hole opens onto the passageway on the outside of the second barrier wall 222 towards the flow gap 25. It can be understood that water can flow back into the guide pipe 21 through the one-way hole and then be discharged from the guide hole of the guide pipe 21. By setting the one-way hole, the reverse flow of water is controlled, thereby achieving reverse cleaning of the guide pipe 21.

[0035] Furthermore, in this embodiment, the elastic element 23 is a spring. A guide element 24 is provided inside the end of the regulating tube 22 away from the guide tube 21, and the end of the regulating tube 22 away from the guide tube 21 is sleeved on the guide element 24. The guide element 24, the regulating tube 22, and the guide tube 21 are coaxially arranged. The spring is sleeved on the guide element 24. One end of the spring is connected to the end of the regulating tube 22 away from the liquid inlet 11, and the other end of the spring is fixed. The guide element 24 guides the guide tube 21 and limits the spring.

[0036] Specifically, the water pressure balancing module also includes a drain end 12. The drain end 12 is disposed on the housing 10. In this embodiment, by configuring the drain end 12 to cooperate with the inlet end 11, water is circulated, thereby achieving continuous humidification.

[0037] Optionally, in this embodiment, the pressure balancing component 20 is provided only at the inlet end 11. Of course, in other embodiments, the pressure balancing component 20 can be provided at both the inlet end 11 and the outlet end 12. In this way, the directions of the inlet end 11 and the outlet end 12 can be switched to achieve bidirectional flow, reduce the formation of scale, and avoid waterway blockage.

[0038] Specifically, on the pressure balancing assembly 20 located at the drain end 12, the relative positions of the regulating pipe 22 and the guide pipe 21 are locked so that the guide hole is always exposed outside the regulating pipe 22, allowing the liquid to be discharged directly from the guide hole. By installing pressure balancing assemblies 20 at both the inlet end 11 and the drain end 12, and selectively activating one of the pressure balancing assemblies 20, the inlet end 11 and the drain end 12 can be interchanged, achieving bidirectional flow, reducing scale formation, and preventing waterway blockage.

[0039] By setting the pressure balancing component 20, the humidifier 100 can be adapted to the water pressure of most areas, thereby ensuring that the pressure when the water flows into the channel is kept within a certain range, avoiding excessive pressure that could damage the internal structure, or insufficient pressure that could lead to poor moisture permeability.

[0040] Furthermore, in this embodiment, a flow channel is provided inside the housing 10. Multiple baffles 13 are also provided within the flow channel. Specifically, the baffles 13 are arranged in an array within the housing 10. It can be understood that by providing the baffles 13, the water flow is evenly filled within the flow channel, improving humidification efficiency. Specifically, when water flows out from the inlet 11, it is successively blocked and diverted by the baffles 13, which can disperse the water flow to various positions within the flow channel and also adjust the water pressure, achieving better moisture discharge efficiency.

[0041] Furthermore, the housing 10 is also provided with vent holes (not shown), and the inner wall of the housing 10 with vent holes is also attached with a waterproof and breathable membrane for exhaust humidification. The humidification device 100 also includes a fan (not shown). The fan is located at the vent holes and increases the humidification rate by accelerating the surface airflow speed, thus rapidly humidifying the air.

[0042] The beneficial effects of the water pressure balancing module and humidification device 100 provided by this utility model include: The water pressure balancing module of this utility model includes an inlet end 11 and a pressure balancing component 20. The pressure balancing component 20 includes a guide pipe 21, an adjusting pipe 22, and an elastic element 23. The guide pipe 21 is fixed and connected to the inlet end 11. A guide hole is provided on the guide pipe 21. The guide hole is used to discharge the liquid in the guide pipe 21. The adjusting pipe 22 is sleeved on the outer periphery of the guide pipe 21 and can move relative to the guide pipe 21 so that the adjusting pipe 22 can cover or expose the guide hole, and a flow gap 25 for liquid to flow is provided between the adjusting pipe 22 and the guide hole. One end of the elastic element 23 is connected to the side of the adjusting pipe 22 away from the inlet end 11, and the other end of the elastic element 23 is fixed. By setting the elastic element 23 and the adjusting pipe 22, when the adjusting pipe 22 is subjected to the discharge pressure of the guide hole, the adjusting pipe 22 moves away from the inlet end 11. When the water pressure at the inlet 11 is low, the elastic element 23 experiences low pressure, the regulating pipe 22 moves a short distance away from the inlet 11, resulting in fewer exposed guide holes and a smaller inflow volume. With a constant flow rate, the smaller flow volume of water entering the channel increases the pressure, making the water pressure at the guide holes greater than that at the inlet 11. Conversely, when the water pressure is high, the elastic element 23 experiences high pressure, the regulating pipe 22 moves a long distance away from the inlet 11, and more guide holes are exposed, equivalent to a larger pipe cross-sectional area. This results in a larger inflow volume, and with a constant flow rate, the larger flow volume of water entering the channel decreases the pressure, making the water pressure at the guide holes less than that at the inlet 11. This invention achieves automatic balancing of the inlet water pressure, maintaining a constant channel water pressure, preventing damage to the internal structure of the humidifier 100, and ensuring humidification effect.

[0043] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
