Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a humidifier and a mist outlet component. Background Art

[0002] Steam humidifiers, also known as warm mist humidifiers or vaporizers, generate steam through heating, which kills microorganisms and other impurities in the water. The mist from a steam humidifier is warm enough not to aggravate colds, allergies, or other conditions, making it healthier than cool mist or other types of humidifiers.

[0003] In related technologies, the heating element of a steam humidifier is fixed to the bottom of a water tank, with a sealed connection between the heating element and the water tank. The mist guide tube is mounted on the heating element. The mist guide tube is equipped with a water discharge mechanism that controls the water level inside the mist guide tube, and the heating element heats the water inside the mist guide tube to form steam. The installation of a water discharge mechanism undoubtedly increases the cost of the humidifier. Furthermore, the requirement for a high degree of sealing between the heating element and the water tank also increases the cost of the humidifier. Utility Model Content

[0004] The utility model provides a mist outlet assembly to reduce the cost of the mist outlet assembly.

[0005] The mist outlet assembly of the present invention includes a mist guide pipe and a heating assembly. The mist guide pipe extends in the up-down direction. The mist guide pipe has a mist guide cavity and a water inlet and a mist outlet connected to the mist guide cavity. The heating assembly is movably arranged in the mist guide cavity in the up-down direction. The heating assembly includes a heating element and a float. The float is connected to the heating element to drive the heating element to move in the up-down direction.

[0006] When the mist outlet assembly of the present invention is working, water enters the mist guide chamber from the water inlet and is heated into steam by the heating element in the mist guide chamber. The steam in the mist guide chamber flows out of the mist outlet in the form of water mist. By configuring the heating element to include a heating element and a float, the water in the mist guide chamber can generate buoyancy on the float. Under the action of this buoyancy, the heating element moves up and down with the water level in the mist guide chamber to heat the water near the upper side of the mist guide chamber. In this way, it is possible to eliminate the need for a water discharge mechanism on the mist guide pipe, thereby reducing the cost of the mist outlet assembly. In addition, when the mist outlet assembly is connected to the water tank, it is possible to eliminate the need for a sealing structure between the heating element and the water tank, further reducing the cost of the mist outlet assembly.

[0007] Optionally, the heating assembly further includes a heat insulator disposed between the heating element and the float. Providing the heat insulator between the heating element and the float reduces heat transfer between the heating element and the float, thereby preventing float deformation and heat waste from the heating element, thereby reducing the cost and energy consumption of the misting assembly.

[0008] Optionally, the heat insulating member and the float are both annular, the heat insulating member is sleeved on the heating element, and the float is sleeved on the heat insulating member. By sleeved the heat insulating member on the heating element and the float on the heat insulating member, assembly of the heating assembly is facilitated, which helps reduce the cost of the misting assembly.

[0009] Optionally, the thermal insulation member and the heating element have an interference fit, and the float and the thermal insulation member have an interference fit. This interference fit between the thermal insulation member and the heating element, and between the float and the thermal insulation member, can, on the one hand, enhance the thermal insulation performance of the thermal insulation member; on the other hand, it further facilitates the assembly of the heating component, thereby reducing the cost of the misting assembly.

[0010] Optionally, a stopper is provided within the mist guide chamber, connected to the mist guide tube. When the water level within the mist guide tube is greater than or equal to a preset water level, the heating component stops upward against the stopper. Providing a stopper within the mist guide chamber limits the heating component. This, on the one hand, prevents the heating component from contacting other non-heat-resistant components and affecting their reliability; on the other hand, it prevents the heating component from falling out of the mist guide tube when the mist outlet assembly is inverted, thereby improving the reliability of the mist outlet assembly.

[0011] Optionally, the retaining member is annular and disposed circumferentially around the mist guide tube, and has a water-passing notch. By configuring the retaining member in an annular shape, the reliability of the retaining member in retaining the heating element can be improved. Furthermore, the provision of the water-passing notch allows water within the mist guide chamber to flow to the upper side of the retaining member, allowing the heating element to fully heat the water within the mist guide chamber.

[0012] Optionally, the float is disposed on the lower side of the heating element. By disposing the float on the lower side of the heating element, the heating element is disposed closer to the upper side of the mist guide cavity, which is more conducive to generating steam in the mist guide cavity, thereby facilitating an increase in the mist output of the mist outlet assembly.

[0013] The utility model also provides a humidifier.

[0014] The humidifier of the present invention comprises a main body and a mist outlet assembly, wherein the main body comprises a water tank; the mist outlet assembly is the mist outlet assembly described in any one of the above items, the mist guide pipe is connected to the main body, and the water inlet is connected to the water tank.

[0015] The humidifier of the present invention can reduce the cost of the humidifier because the cost of the mist outlet component is relatively low.

[0016] Optionally, the mist outlet assembly further includes a wire, one end of which is electrically connected to the heating element; a through-hole is provided at the lower portion of the water tank, the main body includes a sealing ring, the sealing ring is fixed in the through-hole, the wire passes through the sealing ring and the other end is electrically connected to the main body. The provision of the sealing ring can improve the sealing between the through-hole and the wire, thereby improving the reliability of the main body.

[0017] Optionally, the wire includes a redundant section disposed within the mist guide chamber, wherein the length of the redundant section is greater than or equal to a predetermined length. By setting the length of the redundant section to be greater than or equal to the predetermined length, the portion of the wire within the mist guide chamber does not restrict the position of the heating component within the mist guide chamber, thereby preventing the wire from moving relative to the sealing ring, thereby achieving a static seal between the wire and the sealing ring, and further improving the reliability of the main body.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figure 1 and Figure 2 As shown, the mist discharge assembly 10 of the present embodiment includes a mist guide tube 1 extending vertically and a heating assembly. The mist guide tube 1 has a mist guide chamber 11, a water inlet 12, and a mist outlet 13 connected to the mist guide chamber 11. The heating assembly is vertically movable within the mist guide chamber 11. The heating assembly includes a heating element 2 and a float 3. The float 3 is connected to the heating element 2 to drive the heating element 2 to move vertically.

[0039] When the mist outlet assembly 10 of the embodiment of the present invention is working, water enters the mist guide chamber 11 from the water inlet 12, is heated into steam by the heating element 2 in the mist guide chamber 11, and the steam in the mist guide chamber 11 flows out from the mist outlet 13 in the form of water mist. By configuring the heating element to include the heating element 2 and the float 3, the water in the mist guide chamber 11 can generate buoyancy on the float 3, and the heating element 2 moves up and down with the water level in the mist guide chamber 11 under the action of the buoyancy, so as to heat the water near the upper side of the mist guide chamber 11. In this way, it is possible to eliminate the need for a water discharge mechanism on the mist guide pipe, thereby reducing the cost of the mist outlet assembly 10. In addition, if Figures 3 to 5 As shown, when the mist outlet assembly 10 is connected to the water tank 202 , there is no need to provide a sealing structure between the heating element 2 and the water tank 202 , thereby further reducing the cost of the mist outlet assembly 10 .

[0040] In some embodiments, as Figure 1 and Figure 2 As shown, the heating component further includes a heat insulating member 4 , which is disposed between the heating element 2 and the float 3 .

[0041] It is understood that when the heating element 2 heats the water in the mist guide chamber 11, the heat from the heating element 2 is transferred to the float 3, which may not only cause the float 3 to deform due to the heat, but also result in heat waste. This requires the use of heat-resistant materials for the float 3, which undoubtedly increases the cost of the mist discharge assembly 10. Moreover, when the mist output is constant, the power of the heating element 2 needs to be increased, which increases the energy consumption of the mist discharge assembly 10.

[0042] By arranging a heat insulating member 4 between the heating element 2 and the float 3, the heat transfer between the heating element 2 and the float 3 can be reduced, thereby avoiding deformation of the float 3 and heat waste of the heating element 2, which is beneficial to reducing the cost and energy consumption of the mist outlet assembly 10.

[0043] Alternatively, as Figure 1 and Figure 2 As shown, the heat insulating member 4 and the float 3 are both ring-shaped, the heat insulating member 4 is sleeved on the heating element 2 , and the float 3 is sleeved on the heat insulating member 4 .

[0044] The float 3 has an annular cavity.

[0045] By sleeve-mounting the heat insulating member 4 on the heating element 2 and sleeve-mounting the float 3 on the heat insulating member 4 , the assembly of the heating component is facilitated, which is beneficial to reducing the cost of the mist outlet component 10 .

[0046] Optionally, the heat insulating member 4 and the heating element 2 are interference fit, and the float 3 and the heat insulating member 4 are interference fit.

[0047] For example, the heat insulating member 4 is a silicone member.

[0048] The interference fit between the thermal insulation member 4 and the heating element 2, and the interference fit between the float 3 and the thermal insulation member 4, on the one hand, can increase the thermal insulation performance of the thermal insulation member 4; on the other hand, it further facilitates the assembly of the heating components, which is conducive to reducing the cost of the mist outlet component 10.

[0049] In some embodiments, as Figure 2 and Figure 5 As shown, a limiter 5 is provided in the mist guide chamber 11, and the limiter 5 is connected to the mist guide pipe 1. When the water level in the mist guide pipe 1 is greater than or equal to a preset water level, the heating component stops upward at the limiter 5.

[0050] Specifically, the preset water level can be the water level in the mist guide tube 1 when the water tank 202 is full of water. That is, when the water tank 202 is full of water, the heating component stops upward against the stopper 5. Of course, the preset water level can also be set to the water level in the mist guide tube 1 when the water tank 202 is in other states as needed.

[0051] By setting a limiter 5 in the mist guide chamber 11, the heating component can be limited. On the one hand, it can prevent the heating component from contacting other non-heat-resistant components and affecting the reliability of other non-heat-resistant components; on the other hand, it can prevent the heating component from falling out of the mist guide pipe 1 when the mist outlet component 10 is inverted, thereby improving the reliability of the mist outlet component 10.

[0052] Alternatively, as Figure 2 and Figure 3 As shown, the limiting member 5 is annular and is arranged around the circumference of the mist guide pipe 1. The limiting member 5 has a water-passing gap 51.

[0053] By providing the retaining member 5 in a ring shape, the reliability of the retaining member 5 in retaining the heating element can be improved. In addition, the provision of the water-passing notch 51 allows the water in the mist-guiding chamber 11 to flow to the upper side of the retaining member 5, so that the heating element 2 can fully heat the water in the mist-guiding chamber 11.

[0054] Optionally, the float 3 is arranged on the lower side of the heating element 2 .

[0055] It can be understood that the heating element 2 heats the water on the upper side of the mist guide cavity 11, which makes it easier to generate steam, and the mist output of the mist output assembly 10 is higher.

[0056] By arranging the float 3 on the lower side of the heating element 2 , the heating element 2 is arranged closer to the upper side of the mist guide cavity 11 , which is more conducive to generating steam in the mist guide cavity 11 , thereby helping to increase the mist output of the mist outlet assembly 10 .

[0057] Alternatively, as Figure 1 and Figure 2 As shown, the mist guide pipe 1 is provided with a sealing groove 14 , and the mist outlet assembly 10 further includes a sealing ring 7 , which is disposed in the sealing groove 14 .

[0058] The sealing ring 7 may be made of silicone.

[0059] like Figure 4 As shown, the lower end of the mist guide tube 1 is inserted into the water tank 202 , and the sealing ring 7 is sealed with the water tank 202 to improve the sealing between the mist guide tube 1 and the water tank 202 .

[0060] The humidifier 100 of the present invention includes a main body and a mist outlet assembly. The main body includes a water tank 202. The mist outlet assembly 10 is any of the above-mentioned mist outlet assemblies 10. The mist guide pipe 1 is connected to the main body, and the water inlet 12 is connected to the water tank 202.

[0061] The humidifier 100 according to the embodiment of the present invention can reduce the cost of the humidifier 100 because the cost of the mist outlet assembly 10 is relatively low.

[0062] In some embodiments, the mist outlet assembly 10 further includes a wire 6, one end of which is electrically connected to the heating element 2. A through-hole 2021 is provided at the lower portion of the water tank 202, and the main body includes a sealing ring 201, which is fixed in the through-hole 2021. The wire 6 passes through the sealing ring 201 and the other end is electrically connected to the main body.

[0063] By providing the sealing ring 201 , the sealing between the through hole 2021 and the wire 6 can be improved, thereby improving the reliability of the main body.

[0064] Optionally, the wire 6 includes a redundant section, which is disposed in the mist guide chamber 11 , and the length of the redundant section is greater than or equal to a preset length.

[0065] The preset length can be the total length of the wire 6 in the mist guide chamber 11 when the heating component stops upward at the limiter 5. The wire 6 is a soft wire and can be bent in the mist guide chamber 11.

[0066] By setting the length of the redundant section to be greater than or equal to the preset length, the portion of the wire 6 located in the mist guide chamber 11 will not limit the position of the heating component in the mist guide chamber 11, so that the wire 6 will not move relative to the sealing ring 201, so that there is a static seal between the wire 6 and the sealing ring 201, further improving the reliability of the main body.

[0067] like Figure 3 、 Figures 5 to 7 As shown, the main body includes an upper cover 203 , the upper cover 203 is connected to the water tank 202 , and the upper part of the mist guide tube 1 is connected to the upper cover 203 .

[0068] The upper cover 203 and the water tank 202 can be snap-connected.

[0069] In the humidifier 100 of the present embodiment, a sealing ring 7 is installed in the sealing groove 14 of the mist guide tube 1. The sealing ring 7 serves to seal the connection between the mist guide tube 1 and the water tank 202, allowing water in the water tank 202 to enter the mist guide chamber 11 through the water inlet 12 of the mist guide tube 1. The sealing ring 7 can better fix the mist guide tube 1 in the water tank 202 and is easy to disassemble and assemble. The heat insulation member 4 is installed on the outer ring of the heating element 2, and the float 3 is installed on the outer ring of the heat insulation member 4, so that the heating element 2 can float in the mist guide chamber 11. The sealing ring 201 is installed at the bottom of the water tank 202, and the wire 6 passes through the sealing ring 201 to supply power and heat to the heating element 2, and the sealing is mutually sealed to prevent water leakage. When the heating element 2 rises to a certain height, it will be limited by the limit member 5 to prevent the heating element 2 from contacting other components and causing deformation of non-heat-resistant components. The heating element 2 moves with the water level under the action of the float 3, and the surface of the heating element 2 is submerged in the water and heated by contact with the upper water level. This simplifies the structure of the humidifier 100 while achieving the same humidification function.

[0070] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments made by ordinary technicians in this field are all within the scope of protection of the present invention.
