Description

Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a humidifying component and an air purifier. Background Art

[0002] With the popularity of air purifiers, users' requirements for air purifiers are gradually increasing. Traditional air purifiers are mainly used for air purification, and are mainly used to adsorb various allergens, PM2.5, PM10, toxic gases or bacteria. In seasons and areas with low humidity, low indoor humidity will lead to a decrease in human comfort, so many families will be equipped with humidifiers to humidify the air. In order to achieve air purification and air humidification at the same time, it is necessary to equip an air purifier and a humidifier at the same time, which occupies a large space. In order to solve the above problems, some existing technologies adopt the method of adding a humidification device inside the air purifier, so that the air can be humidified while being purified, reducing the occupied space. However, due to the surface structure design defects of the humidification device of this type of air purifier, the noise generated when the air flows through the humidification device is relatively large, which affects the user experience. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a humidifying component and an air purifier to reduce the noise generated when the air purifier is running.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A humidifying component is installed in the air inlet end of the air purifier, comprising a water storage tank and a water absorbing member;

[0006] In the axial direction of the water storage tank, the outer diameter of the water storage tank gradually decreases along the air outlet direction;

[0007] The water absorbing member is embedded in the water storage tank.

[0008] An air inlet hole is provided on the surface of the water storage tank. In the radial direction of the water storage tank, the projection area of ​​the air inlet hole is located on the circumferential side wall of the water absorbing member.

[0009] Furthermore, the air inlet is located at the air outlet end of the water storage tank.

[0010] Furthermore, the air inlet holes are distributed along the axial direction of the water storage tank, and the length of the air inlet holes is 0.3 to 0.5 of the height of the water storage tank.

[0011] Furthermore, the water storage tank and the water absorbing member are coaxially arranged.

[0012] Furthermore, the outer surface of the water storage tank has a first curved surface;

[0013] The inner concave surface of the first arc surface is arranged away from the water absorbing component.

[0014] Furthermore, the first curved surface is located at the air outlet end of the water storage tank.

[0015] In order to solve the above technical problems, another technical solution adopted by the utility model is:

[0016] An air purifier comprises an air outlet component, an air inlet component and a humidifying component as in the above technical solution;

[0017] The air inlet component is in communication with the air outlet component;

[0018] The humidifying component is embedded in the air inlet component.

[0019] Furthermore, one end of the humidifying component is pressed against the air inlet end of the air outlet component.

[0020] Furthermore, a limiting boss is provided in one end of the air inlet assembly away from the air outlet assembly, and the humidifying assembly is sleeved on the limiting boss.

[0021] Further, the air inlet assembly includes a filter and an air inlet cover;

[0022] The air inlet cover is arranged outside the filter, and the filter cover is arranged outside the humidifying component.

[0023] The beneficial effects of the utility model are as follows: since the outer diameter of the water storage tank gradually decreases along the air outlet direction, the outer surface of the water storage tank forms a cone-like structure, which reduces the noise generated when the airflow flows along the surface of the water storage tank; since the air inlet hole is directly opposite to the water absorbent member, the airflow can quickly contact the water absorbent member and take away the moisture on the surface of the water absorbent member, thereby quickly humidifying the air.

[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0031] Please refer to Figure 1 as well as Figure 2 An air purifier includes an air outlet assembly 100, an air inlet assembly 200 and a humidifying assembly 300; the air inlet assembly 200 is connected to the air outlet assembly 100; the humidifying assembly 300 is embedded in the air inlet assembly 200; the humidifying assembly 300 includes a water storage tank 310 and a water absorbing member 320; in the axial direction of the water storage tank 310, the outer diameter of the water storage tank 310 gradually decreases along the air outlet direction; the water absorbing member 320 is embedded in the water storage tank 310; an air inlet hole 311 is opened on the surface of the water storage tank 310, and in the radial direction of the water storage tank 310, the projection area of ​​the air inlet hole 311 is located on the circumferential side wall of the water absorbing member 320. Preferably, the water absorbing member 320 can be a water absorbing material such as a sponge or a water absorbing cloth, and the water absorbing member 320 is a cylindrical structure with two ends interconnected.

[0032] It can be understood that since the outer diameter of the water tank 310 gradually decreases along the air outlet direction, the outer surface of the water tank 310 forms a cone-like structure, which reduces the noise generated when the airflow flows along the surface of the water tank 310. Since the air inlet hole 311 is directly opposite to the water absorbent member 320, the airflow can quickly contact the water absorbent member 320 and take away the moisture on the surface of the water absorbent member 320, thereby quickly humidifying the purified air.

[0033] In some embodiments, the air inlet 311 is located at the air outlet end of the water storage tank 310 to ensure that the air can contact the water absorbing member 320 to ensure the humidification effect.

[0034] In some embodiments, the air inlet holes 311 are distributed along the axial direction of the water storage tank 310, and the length of the air inlet holes 311 is 0.3 to 0.5 of the height of the water storage tank 310. When the length of the air inlet holes 311 is too large, the water storage capacity of the water storage tank 310 will decrease. If the length of the air inlet holes 311 is too short, the contact area between the purified air and the water absorbing member 320 will decrease, the humidification effect will be poor and the humidification efficiency will decrease. When the length of the air inlet holes 311 is 0.3 to 0.5 of the height of the water storage tank 310, it can ensure that the water storage capacity meets a certain usage time and the humidification efficiency and humidification effect can be ensured. Preferably, the length of the air inlet holes 311 is 0.33, 0.35, 0.44, 0.45, 0.46, 0.47, 0.48 or 0.49 of the height of the water storage tank 310.

[0035] In some embodiments, the water storage tank 310 and the water absorbing member 320 are coaxially arranged to ensure that air entering the water storage tank 310 from all angles can contact the water absorbing member 320 to ensure the humidification effect.

[0036] In some embodiments, the outer surface of the water storage tank 310 has a first curved surface 312; the inner concave surface of the first curved surface 312 is arranged away from the water absorbing member 320. The outer surface of the water storage tank 310 also has a second curved surface 313, the first curved surface 312 and the second curved surface 313 are respectively located at the air outlet end and the water storage end of the water storage tank 310, and the second curved surface 313 is arranged along the inner concave surface toward the water absorbing member 320, so that the water storage capacity of the water storage tank 310 is maximized. The arrangement of the second curved surface 313 can also guide the air, so that the purified air moves along the second curved surface 313 to the first curved surface 312 and contacts the water absorbing member 320 to achieve humidification.

[0037] In some embodiments, one end of the humidifying component 300 is pressed against the air inlet end of the air outlet component 100. Specifically, the water storage tank 310 and the water absorbing member 320 are pressed against the air inlet end of the air outlet component 100. A limiting boss 210 is provided in one end of the air inlet component 200 away from the air outlet component 100. The humidifying component 300 is sleeved on the limiting boss 210. Specifically, the bottom of the water storage tank 310 is coaxially arranged and matched with the limiting boss 210, so that the water storage tank 310 can be covered on the limiting boss 210. Through the cooperation between the air inlet component 200 and the limiting boss 210, the humidifying component 300 can be limited, thereby improving the stability of the humidifying component 300. Specifically, the limiting boss 210 is truncated cone-shaped.

[0038] In some embodiments, the air inlet assembly 200 includes a filter 220 and an air inlet cover 230; the air inlet cover 230 is arranged outside the filter 220, and the filter 220 is arranged outside the humidification assembly 300, wherein the limiting boss 210 is arranged at the bottom of the air inlet cover 230. The filter 220 is used to purify and adsorb the air, and an air inlet channel 400 is formed between the filter 220 and the water storage tank 310, which is used to humidify the purified air to ensure the humidification effect; the air outlet assembly 100 includes a housing 110, a centrifugal fan and a downwind duct 120, the centrifugal fan is installed in the downwind duct 120, the downwind duct 120 is embedded in the housing 110, and the air inlet end of the downwind duct 120 is pressed against the end surface of the air outlet end of the water absorbing member 320. In order to facilitate the addition of water to the water storage tank, the air inlet cover 230 is detachably connected to the housing 110.

[0039] The working principle of the utility model is:

[0040] Driven by the centrifugal fan, the external air passes through the air inlet cover 230 and the filter 220, contacts the water absorbent 320, takes away the moisture on the surface of the water absorbent 320, enters the downwind duct 120, and is discharged from the top of the housing 110, thereby achieving air purification and humidification.

Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
