[0020] The following is for reference. Figures 1 to 4 This invention describes a power-free water pump humidifier according to an embodiment of the present invention.

[0021] The power-free water pump humidifier of this utility model includes a housing 100, a water tank 200, an evaporation component, and a pumping component.

[0022] Reference Figure 3The housing 100 is provided with an air inlet 120 and an air outlet 110. An evaporation chamber and an exhaust channel 111 are provided inside the housing 100. The evaporation chamber has a first cavity 121 and a second cavity 122. The first cavity 121 is connected to the air inlet 120. The exhaust channel 111 is connected between the second cavity 122 and the air outlet 110. A fan is provided in the exhaust channel 111. The fan is used to drive the air to flow towards the air outlet 110, so that the air enters the first cavity 121 from the air inlet 120, then passes through the evaporation medium 510 between the first cavity 121 and the second cavity 122, and then flows from the second cavity 122 through the exhaust channel 111 and is discharged from the air outlet 110.

[0023] The water tank 200 is connected to the lower side of the housing 100. The water tank 200 is provided with a water storage chamber and is used to supply water to the evaporation components. The water tank 200 and the housing 100 can be detachably connected by snap-fit, bolt connection, threaded connection or other suitable means to facilitate the removal of the water tank 200 for cleaning. The evaporation assembly includes an evaporation medium 510 disposed in the evaporation chamber and a water distributor 520. The evaporation medium 510 can be a honeycomb paper wet film, a polymer material wet film, a hydrophilic sponge, a stainless steel wire mesh, etc. The evaporation medium 510 is disposed between the first chamber 121 and the second chamber 122, so that airflow can pass through the evaporation medium 510 to achieve the purpose of air humidification. The water distributor 520 is disposed on the upper side of the evaporation medium 510. The water distributor 520 is used to evenly distribute the water in the water distributor 520 on the upper surface of the evaporation medium 510, so that the water distributed on the upper surface of the evaporation medium 510 can penetrate downward into the entire evaporation medium 510 under the action of gravity.

[0024] Pumping components, refer to Figure 2 The pump includes a pump body 560 and a driver 550. The pump body 560 has a suction port, a discharge port and a power input shaft. Rotating the power input shaft can make the suction port draw water and the discharge port discharge water. The pump body 560 is a conventional component in this field, and its specific structure will not be described in detail here.

[0025] The water pump body 560 is used to transport water from the water tank 200 to the water distributor 520. The water pump body 560 is located at the bottom of the housing 100. Even if the water pump body 560 leaks, the leaked water can be directly discharged back to the water tank 200 without flowing to electronic components such as the driver 550.

[0026] The suction port is equipped with a suction pipe that extends downward to the bottom of the inner side of the water tank 200. The drain port is equipped with a drain pipe that extends upward to connect with the water distributor 520. During normal use, the liquid level in the water tank 200 is below the water pump body 560, and the power input shaft will not come into contact with the water. The driver 550 is located inside the housing 100 and above the water pump body 560. The power output shaft of the driver 550 is connected to the power input shaft through a linkage mechanism.

[0027] When in use, the control driver 550 is started. The driver 550 drives the power input shaft of the water pump body 560 through the linkage mechanism, so that the water pump body 560 draws water from the water tank 200 and delivers it to the water distributor 520. The water distributor 520 distributes the water to the evaporation medium 510 to wet the evaporation medium 510. At the same time, the control fan is started so that the air flowing in from the air inlet 120 passes through the evaporation medium 510 and is discharged from the air outlet 110 to achieve the purpose of air humidification. In this design, the water pump body 560 and the driver 550 are set separately, with the driver 550 positioned above the water pump body 560. The water pump body 560 is not connected to electricity. Even if the water pump body 560 malfunctions or its seal fails after long-term operation, the leaked water will not flow to the driver 550, thus maintaining water and electricity separation and improving safety performance.

[0028] In some embodiments of this utility model, reference is made to Figure 4 The linkage mechanism includes a first gear 551 mounted on the power output shaft and a second gear 561 mounted on the power input shaft, with the first gear 551 meshing with the second gear 561. The driver 550 can be an electric motor, and the linkage is achieved through the gear mechanism. This ensures that the transmission between the electric motor and the water pump body 560 is less prone to slippage and has a precise transmission ratio, preventing the water pump body 560 from rotating too fast or too slow. The power input shaft and the second gear 561 can be integrally formed gear shafts, resulting in a smaller overall radial dimension and a more compact structure for the water pump body 560. This avoids the problem of the second gear 561 being too large and needing to extend into the water tank 200, thus requiring clearance space within the water tank 200.

[0029] In some embodiments of this utility model, the water pump body 560 is a diaphragm pump. The output flow of the diaphragm pump is stable, which is beneficial for maintaining a suitable level of humidity in the evaporation medium 510. This prevents the evaporation medium 510 from being too wet, resulting in too small pores and too low airflow, and also prevents insufficient humidity of the evaporation medium 510, resulting in insufficient water evaporation. At the same time, the diaphragm pump adopts a static seal design, which has good sealing performance. Moreover, as water evaporates, the water circulating in the water tank 200 and the evaporation chamber will gradually harden, and the diaphragm pump can transport hard water, making it suitable for this utility model.

[0030] In some embodiments of this utility model, both the first cavity 121 and the evaporation medium 510 are annular. The evaporation medium 510 and the first cavity 121 are sequentially fitted onto the outside of the second cavity 122, and the exhaust channel 111 is disposed on the upper side of the second cavity 122. The air inlet 120 is disposed on the side wall of the housing 100 and directly communicates with the first cavity 121. The annular first cavity 121 makes full use of the space inside the housing 100, and the flow area when the air flows through the evaporation medium 510 is large, which is conducive to the air flow carrying away more water vapor and the humidification effect is better. Among them, the evaporation medium 510 can be configured as an annular sponge with a certain thickness, which has a large mass transfer area and is conducive to improving the evaporation efficiency.

[0031] In some embodiments of this utility model, a drain hole is provided at the bottom of the evaporation chamber, and the drain hole is connected to the water tank 200. A return water pipe can be provided at the drain hole, which extends downward into the water tank 200. After the excess water is saturated by the evaporation medium 510, it will be recycled back into the water tank 200 through the drain hole, thereby keeping the evaporation chamber moist but not too damp.

[0032] In some embodiments of this utility model, reference is made to Figure 1 The housing 100 has a top cover 300 on its top, and the air outlet 110 is annular and located on the lower side of the top cover 300. By making the air outlet 110 annular, it is easy for the humidified air to be dispersed in all directions.

[0033] In some embodiments of this utility model, the top cover 300 is provided with a control panel 310. The fan, driver 550, negative ion generator, and ultraviolet lamp are all electrically connected to the control panel 310, which is used to control the start and stop of the fan, driver 550, negative ion generator, and ultraviolet lamp. By placing the control panel 310 on the top of the housing 100, it is convenient for the user to observe and operate the control panel 310.

[0034] In some embodiments of this invention, the bottom surface of the top cover 300 is a conical shape with a diameter that gradually decreases from top to bottom. This serves to guide airflow and reduce air resistance.

[0035] In some embodiments of this utility model, the inner wall of the exhaust channel 111 is funnel-shaped. The fan includes a drive motor 540 and a centrifugal impeller 530. The drive motor 540 is located at the bottom end of the top cover 300, and the centrifugal impeller 530 is located at the bottom end of the exhaust channel 111. The axial directions of both the drive motor 540 and the centrifugal impeller 530 are vertical. The drive motor 540 and the centrifugal impeller 530 occupy the middle position of the space between the top cover 300 and the evaporation chamber, making the exhaust channel 111 annular with a diameter that gradually increases from bottom to top. The air outlet direction of the centrifugal impeller 530 is along its radial direction, which matches the shape of the exhaust channel 111, thus reducing wind resistance, increasing air volume, and improving the air humidification effect.

[0036] In some embodiments of this utility model, the water distributor 520 is an annular groove shape, adapted to the annular evaporation medium 510. The bottom of the water distributor 520 is provided with multiple water distribution holes, so that the water flowing out of the water distribution holes can penetrate into the evaporation medium 510. The water distributor 520 is fitted on the outer side of the bottom end of the exhaust channel 111. The side wall of the funnel-shaped exhaust channel 111 has a diameter that gradually increases from bottom to top, and the smaller diameter part at the bottom is inserted into the inside of the water distributor 520. In this way, the space inside the housing 100 is fully utilized to place the water distributor 520, while promoting the airflow to pass through the evaporation medium 510 instead of passing through the side of the water distributor 520, which is beneficial to improving the evaporation efficiency.

[0037] In some embodiments of this invention, the air inlet 120 is equipped with a filter. The filter can be a HEPA filter. Thus, this invention can also filter harmful dust, pollen, and other particulate matter in the air, thus performing air filtration.

[0038] In some embodiments of this invention, a negative ion generator is installed inside the exhaust channel 111. The negative ion generator can be located at the air outlet 110; thus, this invention can also activate the negative ion generator to remove odors from the air, making the air fresher.

[0039] The bottom of the housing 100 is equipped with an ultraviolet lamp facing the water tank 200. This allows the ultraviolet lamp to be activated to sterilize and disinfect the water in the water tank 200, resulting in cleaner air.

[0040] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
