Abstract
Description
Technical Field
[0001] This utility model relates to an energy-saving and environmentally friendly humidifier, specifically a non-powered air humidifier. Background Technology
[0002] In northern Chinese cities, winters are extremely dry during heating season, with indoor humidity often below 20%. Furthermore, many newly built houses use underfloor heating, leading to even drier floors. Dry floors attract dust, causing it to float in the air and be inhaled, potentially causing illness. Nosebleeds are particularly common during the heating season. Research has found that this is due to the low humidity combined with the inhalation of large amounts of dust, forming hardened nasal mucus that can easily puncture the nasal mucosa, causing nosebleeds upon waking. Therefore, humidifiers are commonly used in northern my country to increase indoor humidity during winter. However, most humidifiers currently in use are electric, which are not only ineffective but also wasteful of electricity and prone to damage. Some families use multiple basins filled with water to increase indoor humidity through evaporation. However, this method is ineffective because the water in the basins is mirror-like, with very little surface area in effective contact with the air, resulting in minimal evaporation and extremely poor humidification. Other families use wet mops and damp towels, but these methods also fail to maintain humidification for long, are time-consuming and laborious, and are extremely inconvenient. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a non-powered air humidifier. It requires no electricity, avoids the problem of electrical breakdowns, is energy-efficient and environmentally friendly, and improves humidification performance, meeting the humidification needs of heated indoor spaces during winter.

[0007] Furthermore, the support frame for the evaporative humidification curtain is arched or square.
[0008] Furthermore, the evaporative humidification curtain support is an arched cylinder composed of several fan-shaped structures.
[0009] Furthermore, the water basin is square or round in shape.
[0010] Furthermore, the evaporative humidification curtain is made of porous fiber material.
[0011] Furthermore, the water tray is made of plastic or stainless steel.
[0012] Furthermore, the evaporative humidification curtain support is made of plastic or stainless steel.
[0013] Furthermore, the bucket holder is made of rigid plastic or stainless steel.
[0014] Furthermore, the non-powered air humidifier includes a water tray, an evaporative humidification curtain bracket, and an evaporative humidification curtain; the water tray has several sets of symmetrically distributed bracket positioning slots on both sides, the evaporative humidification curtain is fitted onto the evaporative humidification curtain bracket, and the evaporative humidification curtain bracket is installed on the bracket positioning slot; the evaporative humidification curtain bracket is an arched, square, or arched cylindrical structure composed of several fan-shaped structures.
[0015] Furthermore, the evaporative humidification curtain structure consists of three layers: a rigid support made of hard plastic or stainless steel in the middle, and porous fiber material on both sides. Utilizing the capillary principle, it can self-absorb water, drawing water from the bottom of the water tray onto the entire fabric, thus achieving powerless humidification.
[0016] The beneficial effects of this utility model are as follows: It provides a non-powered air humidifier. It has no mechanical power source, is self-priming, requires no electricity, is energy-saving and environmentally friendly, and avoids the problem of electrical appliances being easily damaged. Multiple evaporative humidification curtains are vertically arranged inside the water tray, reducing the size of the humidifier, increasing the effective contact area between water and air, and improving the evaporation effect. It can meet the humidification needs of indoor air in winter heating systems. Its main advantages are as follows:
[0017] (1) When the non-powered air humidifier is used, it is placed on a heated floor. The heat of the floor will be transferred to the bottom plate of the humidifier's water tray, and the water temperature in the water tray will rise, which will accelerate the evaporation rate of the water in the water tray.
[0018] (2) Multiple evaporative humidification curtains are installed vertically inside the water tray, which increases the effective contact area between water and air, reduces the volume of the humidifier, and improves the evaporation effect.
[0019] (3) The evaporative humidification curtain fabric is made of porous fiber material. Utilizing the capillary principle (like an oil lamp wick absorbing oil), it draws water from the bottom of the water tray onto the curtain without power (no electricity). Research shows that the fiber fabric currently being tested can absorb water up to a height of 260 mm. Therefore, the height of the evaporative humidification curtain is approximately 260 mm, which is equivalent to the height of the water it can absorb. The daily evaporation water volume per square meter is about 1-2 kg. During the heating season, the indoor humidity is less than 20%. Using this non-powered humidifier in a 12-square-meter bedroom (after absorbing water through the evaporative curtain, the humidity near the humidifier is greater than 40%, and the indoor humidity can be increased by about 15%), non-powered underfloor heating humidification is achieved.

Detailed Implementation
[0031] Example
[0032] Reference Figures 1-6 A non-powered air humidifier includes a bottled purified water container 1, a water container holder 2, a water tray 3, an evaporative humidification curtain support 4, and an evaporative humidification curtain 5. The water container holder is placed on one side of the water tray, and the bottled purified water is placed on the water container holder. The opening of the bottled purified water is sealed with a sealing film 11. A water outlet pipe 12 and an L-shaped air inlet pipe 13 are respectively provided below the water container holder. A pin 21 corresponding to the position of the opening is provided on the water container holder below the opening of the bottled purified water. After the bottled purified water is placed on the water container holder, the pin can pierce the sealing film. Several sets of symmetrically distributed support positioning slots 31 are provided on both sides of the water tray. A water level display scale 32 is provided inside the water tray. The top and bottom of the water level display scale are respectively provided with a maximum water level line 322 and a minimum water level line 321. The air inlet at the top of the L-shaped air inlet pipe is flush with the highest water level line, and the water outlet is flush with the lowest water level line. The evaporative humidification curtain is located on the evaporative humidification curtain bracket, which is installed in the bracket positioning groove. The air inlet at the top of the L-shaped air inlet pipe is lower than the height of the water tray. The evaporative humidification curtain is printed with an icon 51 bearing a trademark or advertising pattern. The evaporative humidification curtain bracket is arched. The evaporative humidification curtain is made of porous fiber material. The water tray is made of plastic or stainless steel. The evaporative humidification curtain bracket is made of plastic or stainless steel. The water tank holder is made of stainless steel.
[0033] In some demanding environments (such as laboratories), non-powered air humidifiers that use purified water can also be used. The purified water is stored in a water tank, the opening of which is sealed with a thin film. A water tank holder is located in the water tray, with a pin in the center. When the water tank is placed in the holder, the pin pushes against the sealed film, allowing water to flow from the tank into the water tray through the outlet pipe. Due to the siphon principle, air enters the tank through the air inlet pipe. When the water level reaches its maximum, the water in the tray submerges the air inlet of the air inlet pipe, preventing further air intake and stopping water supply. When the water level in the tray reaches its maximum, exceeding the air inlet of the air inlet pipe, the tank automatically replenishes water. This replenishment principle is the same as that of water dispensers, utilizing the siphon principle.
[0034] The evaporative humidification curtain is made of porous fiber cloth. Utilizing the capillary adsorption principle of plant fibers, water from the automatic water tray is absorbed onto the fabric, increasing the evaporation area. The fabric softens after absorbing water, so a support frame is designed in the middle of the evaporative humidification curtain fabric. The support frame can be made in various shapes, is aesthetically pleasing, sturdy, and durable. Multiple evaporative humidification curtains can be arranged and installed in the water tray. The curtains are installed piece by piece, making them easy to remove for cleaning or replacement. The more evaporative humidification curtains installed in the water tray, the larger the evaporation area, the greater the evaporation volume, and the better the humidification effect. The evaporative humidification curtains can be made in round or square shapes according to user preferences. Various logos or advertising patterns can also be printed on the curtains. Example
[0035] Reference Figure 7 Based on the technical solution of Embodiment 1, the evaporative humidification curtain support can be designed as square.
[0036] Example 3
[0037] like Figure 8 and 9 As shown, based on the technical solution of Embodiment 1, the evaporative humidification curtain support can be designed as an arched cylinder composed of several fan-shaped structures. Example
[0038] Reference Figure 10 A non-powered air humidifier includes a water tray, an evaporative humidification curtain support, and an evaporative humidification curtain. Several symmetrically distributed support positioning slots are provided on both sides of the water tray. The evaporative humidification curtain is fitted onto the evaporative humidification curtain support, which is installed in the support positioning slots. The evaporative humidification curtain support is an arched, square, or domed cylindrical structure composed of several fan-shaped structures. This embodiment is a tankless water replenishment humidifier, using other water replenishment methods for non-powered water replenishment. It is very simple to use; simply add water to the water tray. Through the porous fibers of the evaporative humidification curtain fabric, water is automatically absorbed from the bottom of the water tray onto the entire fabric using capillary action, increasing the evaporation area and achieving humidification without mechanical power. When the indoor humidity is high, the water on the humidification curtain evaporates slowly; when the indoor humidity is low, the water on the humidification curtain evaporates faster. Without a power source, it achieves automatic adjustment and control of indoor humidity.
