Abstract

This application relates to a humidifying device, including a shell, an air duct and an air blowing apparatus disposed in the shell, wherein a mist outlet channel, an atomizing cavity and a heating cavity communicated with the mist outlet channel are disposed in the shell; the air duct includes a first air duct communicated with the atomizing cavity and a second air duct communicated with the heating cavity; the air blowing apparatus is provided with an air outlet member, and the air outlet member is aligned with the first air duct and the second air duct, and is configured to supply a first air flow to the first air duct and supply a second air flow to the second air duct. When the humidifying device operates, the first air flow forms an atomized air flow and the second air flow forms a heated air flow then are mixed.

First claim

What is claimed is:

1. A humidifying device, comprising:
a shell, wherein a mist outlet channel, an atomizing cavity and a heating cavity communicated with said mist outlet channel are disposed in said shell;
an air duct, disposed in said shell and comprising a first air duct communicated with said atomizing cavity and a second air duct communicated with said heating cavity;
an air blowing apparatus, disposed in said shell and provided with an air outlet member for outflow of an air flow, wherein said air outlet member is configured to provide a first air flow to said first air duct and a second air flow to said second air duct, wherein
when said humidifying device operates, said first air flow enters said atomizing cavity through said first air duct to form an atomized air flow, said second air flow enters said heating cavity through said second air duct to form a heated air flow, and then said atomized air flow and said heated air flow enter said mist outlet channel, and are mixed in said mist outlet channel and sprayed out from said humidifying device,
wherein said air outlet member is provided with at least one first air outlet and at least one second air outlet, said first air outlet is disposed aligned with said first air duct to provide said first air flow to said first air duct, and said second air outlet is disposed aligned with said second air duct to provide said second air flow to said second air duct,
said air outlet member extending into said air duct, said air duct being separated by said air outlet member to form said first air duct and said second air duct, said first air outlet facing a side where said first air duct is located, and said second air outlet facing a side where said second air duct is located.

2. The humidifying device according to claim 1 , wherein an opening size of said first air outlet is greater than an opening size of said second air outlet.

3. The humidifying device according claim 2 , comprising a seat and a water tank, wherein said water tank is disposed on said seat, and said seat is provided with an atomizing groove forming a partial space of said atomizing cavity and a heating groove forming a partial space of said heating cavity;
openings of said atomizing groove and said heating groove all face a side where said water tank is located; and said air outlet member protrudes from a side of said seat facing said water tank.

4. The humidifying device according to claim 3 , wherein said water tank is provided with a bottom wall of said water tank near said side where said seat is located, said bottom wall of said water tank is provided with at least two spaced air duct partitions protruding toward said side where said seat is located, and said air duct partitions and a wall surface of said seat facing said air duct partitions jointly form said air duct.

5. The humidifying device according to claim 3 , wherein said air blowing apparatus further comprises a waterproof component, said waterproof component comprises a waterproof member and an elastic support member, and said waterproof member is supported on said elastic support member and covers an air outlet of said air outlet member for air discharging;
said waterproof member is movable under a force to open said air outlet and enable said elastic support member to be deformed; and after said force applied to said waterproof member is removed, said elastic support member recovers to drive said waterproof member to move until covering said air outlet.

6. The humidifying device according to claim 5 , wherein said waterproof member comprises a waterproof portion for covering an air outlet position of said air outlet member and a connection portion connected to a side of said waterproof portion; one end of said elastic support member is abutted on said seat, and the other end of said elastic support member is abutted on said connection portion; and
said waterproof component further comprises a guide member, wherein said guide member is disposed around an outer side of said elastic support member.

7. The humidifying device according to claim 3 , further comprising a cover disposed on said heating groove, and an inner wall of said heating groove and said cover jointly form said heating cavity; and
said cover is provided with a first opening and a second opening, wherein said first opening is communicated with said second air duct, and said second opening is communicated with said mist outlet channel.

8. The humidifying device according to claim 7 , wherein a wall of said cover far away from said heating groove is a top wall of said cover, and said second opening is disposed on said top wall of said cover; and
said top wall of said cover is provided with a surrounding portion disposed around said second opening, and said surrounding portion is disposed obliquely relative to a vertical direction; or said top wall of said cover entirely is disposed obliquely relative to a vertical direction.

9. The humidifying device according to claim 3 , wherein said atomizing groove is further provided with a muffler; and
said muffler is funnel-shaped, a smaller opening of said funnel-shaped muffler is a fourth opening, a larger opening of said muffler is a fifth opening, said fourth opening is aligned with said opening of said atomizing groove, and said fifth opening is communicated with said mist outlet channel.

10. The humidifying device according to claim 9 , wherein said muffler has a circumferential sidewall, at least part of which is located inside said air duct, a first ventilation hole is provided on said circumferential sidewall located inside said air duct, and said first air duct is internally communicated with said muffler through said first ventilation hole.

11. The humidifying device according to claim 3 , wherein said seat is further provided with a water groove and a communication groove, said water groove is configured to supply water to said heating groove, said communication groove communicates said heating groove and said water groove, and said communication groove is further provided with a water level measurement apparatus configured to measure a water level in said communication groove.

12. The humidifying device according to claim 11 , wherein a water barrier component is disposed in said communication groove, said water barrier component comprises at least two water barriers, said water barriers are arranged at intervals along an extending direction of said communication groove, and one end of each said water barrier near a bottom of said communication groove is provided with a water passing hole for water to flow through; and said water level measurement apparatus is disposed between two adjacent water barriers.
