[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Please also refer to Figures 1 to 4 As shown, the preferred embodiment of the bladeless purification and humidification fan of the present invention comprises a purification and humidification unit 1 and a bladeless fan unit 2 spaced apart from each other, and a connector 3 is provided between the purification and humidification unit 1 and the bladeless fan unit 2 to connect them to each other. Figure 1 and Figure 2 As shown, the purification and humidification unit 1 and the bladeless fan unit 2 are spaced apart from each other and close to each other, and the connecting member 3 is arranged on the sides of the purification and humidification unit 1 and the bladeless fan unit 2.

[0025] A moisture outlet 11 is provided on one side of the purification and humidification unit 1, and a fan air inlet 21 and a fan air outlet 22 are provided on different sides of the bladeless fan unit 2. The fan air inlet 21 and the moisture outlet 11 are close to each other and coaxial with the moisture outlet 11. The airflow direction of the fan air outlet 22 is different from that of the fan air inlet 21. The airflow direction of the fan air inlet 21 is from bottom to top, and the airflow direction of the fan air outlet 22 is from right to left. Figure 2 As shown in the figure, the dotted line with an arrow indicates the direction of air flow.

[0026] The purification and humidification unit 1 includes a humidification housing 12, and a wet outlet 11 is provided at one end of the humidification housing 12. A humidification air inlet 13 is also provided on the humidification housing 12. A water tank 14, a water pump 15, a purification filter 16, a wet curtain 17, a humidification fan 18, and a humidification motor 19 are respectively provided in the humidification housing 12. The water pump 15 transports the water in the water tank 14 to the wet curtain 17 through a water pipe (not shown in the figure) to wet the wet curtain 17. The purification filter 16 purifies the air flowing through it, and the wet curtain 17 increases the humidity of the air flowing through it. The humidification motor 19 drives the humidification fan 18 to rotate, driving the air from the humidification air inlet 13 into the humidification housing 12, where it is purified by the purification filter 16 and humidified by the wet curtain 17 before flowing out from the wet outlet 11.

[0027] The humidifier air inlet 13 consists of a plurality of small circular holes in the humidifier housing 12. This inlet 13 corresponds to the location of the purification filter 16. External air enters the humidifier housing 12 through the humidifier air inlet 13 and then flows through the purification filter 16, where it is purified. The purification filter 16 is a hollow HEPA filter element. A wet curtain 17 is located in the center of the purification filter 16.

[0028] like Figure 2 As shown, under the condition that the humidification motor 19 drives the humidification fan blades 18 to rotate, the external air enters the humidification shell 12 from the humidification air inlet 13 located on the side of the humidification shell 12, is purified by the purification filter 16 and humidified by the wet curtain 17 in turn, and then flows out of the humidification shell 12 from the wet outlet 11 located at the top of the humidification shell 12.

[0029] The bladeless fan unit 2 includes a fan housing 23 and a rotor assembly 24. The fan inlet 21 and the fan outlet 22 are respectively provided on the fan housing 23. The rotor assembly 24 is disposed in the fan housing 23 and is not visible. The rotor assembly 24 drives air from the fan inlet 21 into the fan housing 23 and then out of the fan housing 23 through the fan outlet 22.

[0030] The humidifying shell 12 includes a humidifying outer shell 110 and a humidifying upper shell 111. The humidifying air inlet 13 is provided on the humidifying outer shell 110, and the humidifying outlet 11 is provided on the humidifying upper shell 111. The lower end of the connecting member 3 is fixed to the humidifying upper shell 111 by the connecting member screw 4. Figure 3 As shown, the connecting piece 3 is fixed to the humidifying upper shell 111 by four connecting piece screws 4 .

[0031] The fan housing 23 includes a fan outer shell 25 and a fan inner shell 26, and the wind wheel assembly 24 is arranged in the fan inner shell 26. The connecting member 3 includes a connecting base 31 and a connecting cover 32 combined together, and a ventilation hole is provided on the connecting base 31. An air inlet end 27 is also provided on the fan inner shell 26. The air inlet end 27 is located in the ventilation hole, and an external thread is provided on the air inlet end 27, and a connecting nut 28 is sleeved on the external thread. The connecting nut 28 is screwed onto the external thread to fix the air inlet end 27 of the fan inner shell 26 to the ventilation hole of the connecting base 31. The wind wheel assembly 24 drives air into the fan housing 23 from the fan air inlet 21, and then out of the fan housing 23 from the fan air outlet 22.

[0032] The present invention sets the bladeless fan unit 2 at the humidification outlet 11 of the purification and humidification unit 1. The fan air inlet 21 sucks the purified humidified air produced by the purification and humidification unit 1 discharged from the humidification outlet 11, and discharges it from the fan air outlet 22 after passing through the wind wheel assembly 24 to increase the speed. The fan motor speed of the bladeless fan unit 2 is greater than the speed of the humidification motor 19 of the purification and humidification unit 1. Without increasing the speed of the humidification motor 19, the air output and wind speed of the purification and humidification unit 1 are increased, while the operating noise of the bladeless purification and humidification fan under the same wind speed conditions is reduced. For example, when the fan motor speed of the bladeless fan unit 2 of the present invention is set to 5000~6000rpm and the speed of the humidification motor 19 is 1500~2000rpm, the wind speed of the humidified air discharged from the fan air outlet 22 is equivalent to the wind speed of the humidified air discharged from the humidification outlet when the speed of the existing humidification motor is set to 7000~10000rpm. The utility model is provided with a bladeless fan unit 2 to lower the speed of the humidifying motor 19 of the purification and humidification unit 1, which not only maintains the original air humidification effect, but also reduces the operating noise of the entire bladeless purification and humidification fan because the motor speed is reduced.

[0033] A wire passage cavity 33 is provided between the connection base 31 and the connection cover 32 , and a wire for controlling the fan motor passes through the wire passage cavity 33 .

[0034] An air inlet cover 5 is provided at the fan air inlet 21, and a detachable connection assembly is provided between the air inlet cover 5 and the fan housing 23. A plurality of vents are provided on the air inlet cover 5.

[0035] The detachable connection component is a magnetic attraction component 6 provided between the air inlet cover 5 and the fan housing 23 , and the air inlet cover 5 is detachably connected to the fan housing 23 via the magnetic attraction component 6 .

[0036] A fan filter 7 is also provided between the air inlet hood 5 and the fan inlet 21. In this embodiment, the air inlet hood 5 and fan filter 7 are conically shaped, with the tip of the cone positioned near the moisture outlet 11. This increases the air intake length of the fan inlet 21 and the amount of humidified air drawn in through the fan inlet 21. A magnetic assembly 6 facilitates removal and cleaning of the air inlet hood 5 and fan filter 7.

[0037] Since the utility model is provided with independent purification and humidification unit 1 and bladeless fan unit 2, users have the following three operating modes when using the bladeless purification and humidification fan:

[0038] (1) When the user only needs to use the fan function, the wind wheel assembly 24 of the bladeless fan unit 2 is turned on. The air at the air inlet does not pass through the purification filter 16 and the wet curtain 17 of the purification and humidification unit 1, which greatly reduces the resistance. The speed of the fan motor of the wind wheel assembly 24 can be lowered to 5000~6000rpm, which not only improves the performance but also reduces the noise.

[0039] (2) When the user only needs to use the purification and humidification functions, the humidification motor of the purification and humidification unit 1 is turned on at a speed of 1500~2000rpm. The external air is purified by the purification filter 16 and humidified by the wet curtain 17. The cross-section of the wet outlet is large and the air duct is short, which greatly reduces the resistance, improves the purification and humidification performance and reduces the noise. At this time, the air is blown upwards and will not blow on people or surrounding objects.

[0040] (3) When the user needs to use the three functions of purification, humidification and fan, the humidification motor 19 and the wind wheel assembly 24 are turned on at the same time. Part of the clean and moist airflow generated by purification and humidification is sucked into the fan housing 23 of the bladeless fan unit 2 through the fan air inlet 21, and is accelerated by the wind wheel assembly 24 and discharged from the fan housing 23 through the fan outlet 22. While ensuring the fan function, the flow and diffusion of the humidified air are improved, and the diffusion speed and diffusion range of the humidified air are also expanded. Through verification, the operating noise of this operating mode is only less than 1% higher than the noise of the operating mode (1).

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
