DETAILED DESCRIPTION

[0027] The drawings of the utility model are only used for example explanation and cannot be understood as the limitation of the utility model. In order to better explain the following embodiments, some components in the drawings can be omitted, enlarged or reduced, and the size of actual products is not represented; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings can be omitted.

[0028] As Figures 1-3 shown in one kind air humidifier, comprising: housing 10, filter screen assembly 20 being arranged in housing 10 and having hollow structure, wind wheel assembly 30 being correspondingly arranged with the hollow structure, air outlet grille 40 being correspondingly arranged with the wind wheel assembly 30 and being arranged at the top of the housing 10, water tank assembly 50 being arranged in housing 10 and being used to supply water for the filter screen assembly 20, and heating assembly 60 being arranged on the air outlet path behind the filter screen assembly 20 and being used to heat the humidified air.

[0029] The air humidifier of the embodiment can provide heating for humidified air in cold weather, so that the humidified air is blown out after temperature is increased, which not only can improve the humidification efficiency of the humidifier, but also makes the blown air more warm and moist in cold weather, and improves the use comfort of the air humidifier. Compared with the humidification mode that the air is heated by the heating assembly first, and then the hot air is mixed with the humid air, the water vapor directly passes through the heating assembly to directly heat the humid air in the embodiment, which not only has better heating effect, but also can avoid the problems of uneven temperature distribution of water vapor and condensation of humid air after evaporation. Specifically, a set of heating assembly 60 is added on the air outlet path behind the filter screen assembly 20 in the embodiment, when the air humidifier is used, the water tank assembly 50 supplies water for the filter screen assembly 20, so that the filter screen assembly 20 is humidified, and the flow rate of air on the surface of the filter screen assembly 20 is increased by the wind wheel assembly 30, so that the water molecules are evaporated into the air to humidify the air. The humidified air is driven by the negative pressure of the wind wheel assembly 30, heated by the heating assembly 60, and then blown out, so that the humidified air is heated.

[0030] Furthermore, this embodiment provides more negative pressure space and air flow space through the hollow filter assembly 20, so that the air can evaporate smoothly and be blown out, thereby improving the humidification efficiency of the air humidifier.

[0031] like Figures 4-6 As shown, in this embodiment, the heating component 60 is disposed between the impeller assembly 30 and the filter assembly 20. This embodiment ensures that the humidified air generated by the filter assembly 20 is fully heated by the heating component 60 before being discharged at high speed through the impeller assembly 30, reducing heat loss. Furthermore, after evaporation, the air is quickly heated by the heating component 60, reducing condensation and reflux, and improving evaporation efficiency. It is a structure that simultaneously possesses both heating and humidification efficiency.

[0032] In other embodiments, the heating component 60 may be located between the impeller assembly 30 and the air outlet grille 40, or at the air outlet of the air outlet grille 40, or on other air outlet paths after passing through the filter assembly 20.

[0033] The heating assembly 60 includes a heating bracket 61 for cooperating with the filter assembly 20 and the impeller assembly 30, and a heating module 62 disposed on the heating bracket 61. By positioning the heating module 62 through the heating bracket 61 and cooperating with the filter assembly 20 and the impeller assembly 30, the airtightness of the negative pressure space in which the air flows can be ensured, thereby improving the air outlet efficiency.

[0034] The heating material of the heating module 62 in this embodiment can be of various types, including but not limited to resistive heating elements and ceramic heating elements, and each type is further divided into many varieties. The heating module 62 can be square or ring-shaped, and generally consists of multiple sets of heating strips. Each heating strip is fixed into a whole by a metal frame, and metal sheets are strung on each heating strip as heat sinks. The ring-shaped heater can be made into multiple rings. The advantage of adding heat sinks is that it can ensure that the heat on the heater can be well exchanged with the air, improve the heat conversion efficiency, and make the blown hot air more uniform and comfortable.

[0035] The heating module 62 described in this embodiment includes a heater 621 and heat dissipation fins 622 connected to the heater 621. The heat dissipation fins 622 increase the contact area with air, thereby improving the heating effect on the air.

[0036] The heating bracket 61 described in this embodiment includes an upper bracket 611 that cooperates with the impeller assembly 30 and a lower bracket 612 that cooperates with the filter assembly 20. The heating module 62 is disposed between the upper bracket 611 and the lower bracket 612. Both the upper bracket 611 and the lower bracket 612 are provided with a converging structure 613 for collecting airflow. The converging structure 613 of the lower bracket 612 allows air to be collected before heating, facilitating centralized heating and improving heating efficiency. The converging structure 613 of the upper bracket 611 allows the heated air to flow out in a concentrated manner, improving airflow efficiency.

[0037] The merging structure 613 described in this embodiment is arranged in a ring shape to form a merging annular groove, which not only realizes merging but also reduces wind resistance.

[0038] In other embodiments, the busbar structure 613 is arranged in a trumpet shape, or the cross-section of the busbar structure 613 is arranged in a stepped shape.

[0039] The impeller assembly 30 described in this embodiment includes an air duct structure 31 that cooperates with the confluence structure 613 and the air outlet grille 40 of the upper support 611, and an impeller body 32 disposed within the air duct structure 31. Similarly, the air duct structure 31 is used to increase the negative pressure space and improve the airtightness of the negative pressure space in which the air flows.

[0040] like Figure 7 As shown, the filter assembly 20 of this embodiment includes a hollow columnar filter support 21 and a filter body 22 attached to the filter support 21. The filter support 21 is provided with a water collection chamber 211 and a plurality of spaced-apart diversion holes 212 communicating with the water collection chamber 211. The water collection chamber 211 collects the water provided by the water tank assembly 50, and the water is distributed to various areas of the filter support 21 through the diversion holes 212, so that the filter body 22 attached to the filter support 21 can be fully and evenly wetted by water, thereby improving the humidification efficiency.

[0041] The water tank assembly 50 described in this embodiment includes a water storage tank 51, a first water pipe 52 and a second water pipe 53 connected to the water storage tank 51; the first water pipe 52 extends to the filter assembly 20 to supply water to the filter assembly 20, and the second water pipe 53 extends to the top of the housing 10 for adding water. That is, the first water pipe 52 pumps water into the water collection chamber 211 through a water pump to wet the filter assembly 20; when the water in the water storage tank 51 is insufficient, water can be added to the water storage tank 51 through the inlet of the second water pipe 53 at the top of the housing 10.

[0042] like Figures 8-9 Combination Figure 2As shown, the water tank assembly 50 is arranged at the bottom of the shell 10, and the water tank assembly 50 further comprises universal wheels 54 arranged at the bottom of the water storage tank 51 and matched with the bottom of the shell 10. When water needs to be added or the water tank assembly 50 needs to be cleaned, the water tank assembly 50 can be pushed out of the shell 10 through the universal wheels 54.

[0043] Since the universal wheels 54 are arranged at the bottom of the water storage tank 51, in order to prevent the water storage tank 51 from moving after being pushed into the shell 10, the bottom of the shell 10 is provided with elastic limiting members 11 for limiting the water storage tank 51. When the water storage tank 51 needs to be pushed out, the elastic limiting members 11 are pressed to make the elastic limiting members 11 consistent with the height of the bottom of the shell 10, so as to facilitate the pushing out of the water storage tank 51. When no external force is applied, the elastic limiting members 11 are protruded to limit the water storage tank 51. In addition, the elastic limiting members 11 of the present embodiment can also assist the installation of the water storage tank 51 in place. The outer wall of the water storage tank 51 is provided with a water pump socket, and the shell 10 is provided with a socket groove matched with the water pump socket. When the water storage tank 51 is installed in place, the elastic limiting members 11 lose the protrusion caused by the external force, limit the water storage tank 51 to the matching of the water pump socket and the socket groove, and then the water pump can be powered on.

[0044] Obviously, the above embodiments of the present application are only examples for clearly illustrating the technical scheme of the present application, and are not intended to limit the specific embodiments of the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
