[0037] For details, please refer to Figures 1 to 6 The present application provides an air outlet device, which may include a fan assembly 10 and a water ion generator 20. The fan assembly 10 has an air inlet 121, an air outlet 122, and an air outlet duct 111 connecting the air inlet 121 and the air outlet 122. The water ion generator includes a protective shell 21 at least partially disposed in the air outlet duct 111 and a water ion assembly 22 installed in the protective shell 21, the protective shell 21 having a water ion generating chamber 2111 and a plurality of air inlet holes 2112 and a plurality of air outlet holes 2113 connecting the water ion generating chamber 2111. In this way, a part of the water ion generator 20 is arranged in the air outlet duct 111 of the fan assembly 10, and the fan assembly 10 can drive air into the water ion generating chamber 2111 through the air inlet hole 2112, and then bring water ions out of the water ion generating chamber 2111 to the air outlet duct 111 through the air outlet hole 2113 of the protective shell 21, thereby improving the diffusion efficiency of water ions. In addition, the protective shell 21 wraps the water ion assembly 22 inside, which can reduce the risk of electric shock of the water ion assembly 22 and improve the safety of the water ion assembly 22.

[0038] Specifically, in one embodiment, the air inlet 2112 is provided on the windward wall 2114 of the protective housing 21, and the air outlet 2113 is provided on the air outlet wall 2115 of the protective housing 21. The windward wall 2114 of the protective housing 21 is arranged toward the air outlet direction of the air outlet duct 111, that is, the direction of air flow in the air outlet duct 111. With such arrangement, the air in the air outlet duct 111 can flow toward the windward wall 2114, and the air inlet 2112 provided on the windward wall 2114 can reduce the collision between the windward wall 2114 and the air, reduce the speed loss of the air driven by the fan assembly 10, avoid the accumulation of water ions in the water ion generating chamber 2111, and improve the diffusion efficiency of the water ions.

[0039] More specifically, if Figure 1 and Figure 4As shown, in one embodiment, the fan assembly 10 includes a fan volute 11, a volute upper cover 12 fixed to the fan volute 11, and a volute side wall 13, the volute side wall 13 is connected to the fan volute 11 to form the outlet duct 111 connected to the air outlet 122, and the water ion generator 20 is installed on the volute side wall 13. In other words, the volute side wall 13 separates the outlet duct 111 in the internal space of the fan volute 11, and the remaining space of the fan volute 11 can be used to install other components. The volute side wall 13 can isolate the air driven by the fan assembly 10 in the outlet duct 111, and prevent the air from entering other spaces of the fan volute 11, causing the fan volute 11 to leak.

[0040] Optionally, in one embodiment, the windward wall 2114 is arranged on the side of the protective housing 21 close to the air outlet of the fan volute 11, and the air outlet wall 2115 is arranged on the side of the protective housing 21 away from the air outlet of the fan volute 11 or on the side of the protective housing 21 extending along the air outlet direction of the air outlet duct 111. The air outlet of the fan volute 11 is the air inlet of the air outlet duct 111, and the driving air of the fan assembly 10 enters the air outlet duct 111 from the air outlet of the fan volute 11. In other words, the air outlet wall 2115 can be arranged on the side adjacent to or opposite to the windward wall 2114. With such arrangement, the windward wall 2114 and the air outlet wall 2115 are distributed on the side of the protective shell 21 in the downwind direction, which is beneficial for the air in the air outlet duct 111 to enter and exit the protective shell 21 and increase the diffusion speed of the water ions.

[0041] Preferably, in one embodiment, the windward wall 2114 extends obliquely from the volute side wall 13 toward the air outlet of the fan volute 11. That is, the angle between the windward wall 2114 and the volute side wall 13 toward the air outlet of the fan volute 11 is greater than 90°.

[0042] Preferably, in one embodiment, the air outlet wall 2115 extends obliquely from the volute side wall 13 toward the air outlet of the fan volute 11. That is, the angle between the air outlet wall 2115 and the volute side wall 13 toward the air outlet of the fan volute 11 is less than 90°.

[0043] In this way, the volute side wall 13 has a converging effect on the air driven by the fan assembly 10, and can guide the air to the air inlet 121 on the windward wall 2114, so that the air entering the water ion generating chamber 2111 has a speed in an oblique direction toward the air outlet 2113, so as to reduce the collision between the air and the air outlet wall 2115, reduce the air speed loss, improve the air intake efficiency of the air inlet 2112 and the air outlet efficiency of the air outlet 2113, thereby improving the diffusion efficiency of water ions.

[0044] For example, Figure 2 and Figure 3 As shown, in one embodiment, a plurality of the air inlet holes 2112 are evenly arranged in an array on the windward wall 2114, and a plurality of the air outlet holes 2113 are evenly arranged in an array on the air outlet wall 2115. The air inlet holes 2112 and the air outlet holes 2113 can be implemented as through holes with rectangular cross-sections. In this way, the air inlet holes 2112 and the air outlet holes 2113 can be distributed on the windward wall 2114 and the air outlet wall 2115 as much as possible while ensuring the structural strength of the windward wall 2114 and the air outlet wall 2115.

[0045] Furthermore, if Figure 1 and Figure 4 As shown, in one embodiment, the air outlet duct 111 has an air guide surface 112 that curves and extends toward the air outlet 122. The fan assembly 10 drives air from the air inlet 121 into the air outlet duct 111, and then, under the guidance of the curved and extended air guide surface 112, the air is discharged from the air outlet 122. In this arrangement, the air inlet 121 and the air outlet 122 are arranged on the same surface, and the fan assembly 10 can be embedded in the ceiling or wall during assembly to reduce the occupation of the bathroom space.

[0046] It is worth noting that a filter assembly can be provided at the air inlet 121 of the volute upper cover 12 to filter the air entering the air outlet duct 111 to prevent dust from entering the water ion generating chamber 2111 of the water ion generator 20 and affecting the water ion generating of the water ion assembly 22 .

[0047] Preferably, if Figure 2 and Figure 3 As shown, in one embodiment, the air inlet 2112 is further provided on the bottom wall 2116 of the protective housing 21. Under the guidance of the air guide surface 112, part of the air will be directed toward the bottom wall 2116 of the protective housing 21. By adding the air inlet 2112 on the bottom wall 2116 of the protective housing 21, the air entering the water ion generating chamber 2111 can be increased, the air intake efficiency is improved, and thus the diffusion efficiency of the water ions is improved.

[0048] In particular, if Figure 2 , Figure 5 and Figure 6As shown, in one embodiment, the volute side wall 13 has a mounting hole 131, and the protective shell 21 is inserted into the mounting hole 131, so that the air inlet hole 2112 and the air outlet hole 2113 are exposed in the air outlet duct 111. In other words, a part of the protective shell 21 is in the air outlet duct 111, and another part of the protective shell 21 is outside the air outlet duct 111. The air inlet hole 2112 and the air outlet hole 2113 are opened on the protective shell 21 in the air outlet duct 111. In this way, the collision volume between the protective shell 21 and the air can be reduced, and the influence of the protective shell 21 on the wind speed of the fan assembly 10 can be reduced.

[0049] Alternatively, if Figure 2 and Figure 5 As shown, in one embodiment, one side of the volute side wall 13 has a positioning groove 132, and the protective shell 21 includes a shell body 211 and a positioning block 212 protruding from the shell body 211, and the positioning block 212 is inserted into the positioning groove 132. When the water ion generator 20 is assembled to the fan volute 11, on the one hand, the positioning groove 132 and the positioning block 212 cooperate with each other, and the water ion generator 20 can be quickly positioned on the volute side wall 13, which can improve the assembly efficiency and reduce the assembly time. On the other hand, the positioning groove 132 and the positioning block 212 can limit the water ion generator 20 from sliding relative to the mounting hole 131 of the volute side wall 13, so that the water ion generator 20 and the volute side wall 13 maintain a stable connection.

[0050] Preferably, if Figure 5 As shown, in one embodiment, the fan assembly 10 further includes a support rib 14 protruding from the fan volute 11, the support rib 14 is arranged on one side of the volute side wall 13, and the support rib 14 abuts against the protective shell 21. On the one hand, the support rib 14 can support the water ion generator 20 so that the water ion generator 20 remains stable on the volute side wall 13. On the other hand, the support rib 14 can increase the structural strength of the volute side wall 13 to prevent the volute side wall 13 from being deformed.

[0051] In particular, since the water ion generator 20 needs to be inserted into the positioning groove 132 during assembly, the end of the mounting hole 131 close to the volute upper cover 12 is open, resulting in a gap between the water ion generator 20 and the volute upper cover 12 after the water ion generator 20 is assembled. The gap needs to be sealed to prevent the air in the air outlet duct 111 from leaking from the gap. Figure 2 and Figure 6As shown, in one embodiment, the protective housing 21 further includes a boss 213 protruding from the housing body 211, the boss 213 is located between the mounting hole 131 and the volute upper cover 12, the side of the boss 213 is attached to the hole wall of the mounting hole 131, and the upper end of the boss 213 is attached to the volute upper cover 12 to fill the gap between the mounting hole 131 and the volute upper cover 12. In this way, the sealing performance at the mounting hole 131 of the volute side wall 13 is improved to avoid air leakage in the air outlet duct 111.

[0052] Alternatively, if Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the fan assembly 10 further includes a fixing column 15 protruding from the fan volute 11, and the protective housing 21 further includes a fixing portion 214 protruding from the housing body 211, and the fixing portion 214 is fixed to the fixing column 15. The fixing portion 214 and the fixing column 15 can be fixed by screwing, and the protective housing 21 is fixed to the fan volute 11 in cooperation with the positioning groove 132 and the positioning block 212, so as to prevent the fan volute 11 from being knocked or vibrated, causing the protective housing 21 to be separated from the fan volute 11.

[0053] In summary, the present application provides an air outlet device that can take into account both the safety protection and diffusion efficiency of the water ion generator 20. The water ion generator 20 is installed in the air outlet duct 111 of the fan assembly 10, and the water ion assembly 22 is wrapped by the protective shell 21 to reduce the risk of electric shock, and the air inlet 2112 is opened on the windward wall 2114 of the protective shell 21 to reduce the obstruction of the air by the windward wall 2114, and the air in the air outlet duct 111 is guided by the volute side wall 13, and the air entering the water ion generating chamber 2111 is guided to move toward the air outlet 2113, thereby improving the air intake efficiency and air outlet efficiency of the water ion generator 20, thereby improving the diffusion efficiency of water ions.

[0054] Furthermore, if Figure 1 As shown, the present application also provides a bathroom heater, comprising: a bathroom heater body 30 and an air outlet device as described above, the bathroom heater body 30 comprises a box body 31, and the air outlet device is arranged in the box body 31. The fan assembly 10 of the air outlet device is integrated into the box body 31, the fan volute 11 of the fan assembly 10 can be a part of the box body 31, the volute side wall 13 of the fan assembly 10 is arranged in the box body 31, and the volute upper cover 12 of the fan assembly 10 can be a part of the box body 31. Through the fan device, the bathroom heater can add water ions to the blown warm air, remove bacteria and allergens in the air, eliminate odors in the room, and ensure the safety and cleanliness of the indoor environment.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
