[0021] In order to make the above objectives, features and advantages of the embodiments of the present invention more clearly understandable, the solutions of the embodiments of the present invention are further described below, and it should be noted that, unless contradiction occurs, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] Although the invention is described in detail in the following description in order to fully understand the embodiments of the present invention, it will be apparent that the embodiments of the present invention may be practiced in other ways than those described in the specification, and that the embodiments in the specification are merely some of the embodiments of the present invention, rather than all of the embodiments.

[0023] 1 to 9, an embodiment of the present invention provides a humidifier, which includes a base 1 having a water storage chamber 32.

[0024] Specifically, the base 1 is provided with a trigger switch 4 and a trigger member 5 located in the water storage chamber 32. Here, a waterproof protective cover 6 is provided on the outside of the trigger switch 4, and the trigger member 5 pushes up the waterproof protective cover 6 when the water level in the water storage chamber 32 rises to a first predetermined water level so as to activate the trigger switch 4 to control the operation of the humidifier.

[0025] That is, the trigger member 5 is configured to rise and fall in accordance with changes in the water level in the water storage chamber 32, and the trigger member 5 is a member that has buoyancy in water.

[0026] In a specific implementation, the trigger switch 4 may be disposed, for example, above the water storage chamber 32. The trigger switch 4 has a switch elastic piece, and when the water level in the water storage chamber 32 rises to a first predetermined water level, the trigger member 5 moves upward so as to push up the waterproof protective cover 6 on the outside of the trigger switch 4, thereby pushing up the switch elastic piece of the trigger switch 4 to operate the trigger switch 4, thereby controlling the operation of the humidifier.

[0027] For example, when the water level in the water storage chamber 32 drops, the trigger member 5 can move down with the drop in the water level, and when the water level falls below a first predetermined water level, the upward pushing force that the switch elastic piece has been receiving disappears, the switch elastic piece is restored, and the trigger switch 4 is turned off. That is, only when the water level rises to the first predetermined water level does the trigger member 5 push up the waterproof protective cover 6, actuating the trigger switch 4 to control the operation of the humidifier. This allows the operation of the humidifier to be flexibly controlled in response to the rise and fall of the water level, and to some extent prevents the humidifier from continuing to operate when there is insufficient water in the humidifier, causing unsafe accidents, thereby improving the safety of using the humidifier.

[0028] Here, the thickness of the waterproof protective cover 6 at the contact position with the trigger member 5 is thinner than the thickness of the waterproof protective cover 6 at other positions.

[0029] By setting it in this manner, the waterproof protective cover 6 provides a certain degree of waterproof sealing effect for the trigger switch 4, and the sensitivity with which the trigger member 5 activates the trigger switch 4 is improved, further ensuring the safety of using the humidifier.

[0030] In the humidifier according to this embodiment, a trigger switch 4 and a water storage chamber 32 are provided on a base 1, a trigger member 5 is located in the water storage chamber 32, and a waterproof protective cover 6 is provided on the outside of the trigger switch 4, and the trigger member 5 pushes up the waterproof protective cover 6 when the water level in the water storage chamber 32 rises to a first predetermined water level, so as to activate the trigger switch 4 to control the operation of the humidifier. That is, only when the water level rises to the first predetermined water level, the trigger member 5 pushes up the waterproof protective cover 6 to activate the trigger switch 4 and control the operation of the humidifier. In this way, the operation of the humidifier is flexibly controlled according to the rise and fall of the water level, and a situation in which the humidifier continues to operate when there is insufficient water in the humidifier and unsafe accidents occur is avoided to some extent, and the safety of the use of the humidifier is improved and the user's experience is good. In addition, since the thickness of the waterproof protective cover 6 at the contact position with the trigger member 5 is thinner than the thickness of the waterproof protective cover 6 at other positions, the waterproof protective cover 6 provides a certain degree of waterproof sealing for the trigger switch 4 and also improves the sensitivity of activating the trigger switch 4, further ensuring the safety of using the humidifier.

[0031] 1 to 9, in some embodiments, the humidifier further includes a heating member 2, and the base 1 further includes a water tank 31 communicating with the water storage chamber 32, and the heating member 2 heats the water in the water tank 31 to create mist. Here, the heating member 2 can be provided on the bottom wall of the water tank 31, for example.

[0032] Specifically, when the water level in the water chamber 32 rises to a first predetermined water level, the trigger switch 4 is actuated to turn on the heating element 2, and when the water level in the water chamber 32 falls to a second predetermined water level, the trigger switch 4 is cut off to turn off the heating element 2. Here, the second predetermined water level is lower than the first predetermined water level.

[0033] That is, when the water level in the water storage chamber 32 rises to a first predetermined water level, the trigger member 5 pushes up the waterproof protective cover 6 on the outside of the trigger switch 4, thereby pushing up the switch elastic piece of the trigger switch 4 to activate the trigger switch 4, and electricity is passed through the heating member 2, which heats the water in the water tub 31 to create mist. When the water level in the water storage chamber 32 falls to a second predetermined water level, the upward force that the switch elastic piece of the trigger switch 4 has been receiving disappears and the switch elastic piece is restored to its original state, at which point the conduction of the heating member 2 is cut off and the operation of the heating member 2 stops. This prevents situations such as dry burning due to a lack of water, improving the safety of using the humidifier.

[0034] For example, when the water level in the water storage chamber 32 and the water tub 31 are in equilibrium and the water level in the water storage chamber 32 reaches or exceeds a first predetermined water level, the trigger member 5 pushes up the switch elastic piece of the trigger switch 4, thereby activating the trigger switch 4 to energize the heating member 2, and the heating member 2 heats the water in the water tub 31. When the water level in the water storage chamber 32 falls below a second predetermined water level, the trigger member 5 moves away from the switch elastic piece of the trigger switch 4, the current between the heating member 2 and the trigger switch 4 is cut off, and the operation of the heating member 2 stops.

[0035] In some embodiments, the humidifier further comprises a spray unit disposed in the water tank. During operation of the humidifier, the heating element 2 heats the water in the water tank 31 to produce mist, which is discharged through the spray unit 9 to humidify the air.

[0036] In some embodiments, referring to Figures 1 to 6, the trigger switch 4 is located above the trigger member 5, which can effectively prevent water from entering the electrical elements of the trigger switch 4 to a certain extent, thereby reducing the occurrence of the phenomenon in which water vapor enters the trigger switch 4 and affects its service life.

[0037] In some embodiments, the waterproof protective cover 6 includes a cover body 61 that covers at least the side of the trigger switch 4 facing the trigger member 5, and the trigger member 5 pushes up the bottom wall of the cover body 61 when the water level in the water reservoir 32 rises to a first predetermined water level, so as to activate the trigger switch 4 and control the operation of the humidifier.

[0038] Specifically, the thickness of the bottom wall of the cover body 61 is equal to or less than the thickness of other positions of the cover body 61. Exemplarily, referring to Figures 5 and 9, the cover body 61 includes a bottom wall and a side wall extending circumferentially upward from an edge of the bottom wall, and the bottom wall and the side wall have the same thickness. When the bottom wall of the cover body 61 is pushed up by the trigger member 5, a certain degree of deformation is also generated in the side wall of the cover body 61, thereby operating the trigger switch.

[0039] 5 and 9, the thickness T1 of the bottom wall of the cover body 61 is the dimension of the bottom wall of the cover body 61 in the direction from the trigger member 5 to the trigger switch 4 (see the Z direction in FIGS. 5 and 9).

[0040] Here, the waterproof protective cover 6 may be, for example, a silicon cover. The silicon cover is soft and has good sealing properties, so that the sealing properties of the trigger switch 4 can be ensured. In addition, when the trigger member 5 rises and contacts the silicon cover, the soft silicon cover is synchronously deformed to contact the trigger switch 4, so that the sensitivity of the trigger is ensured.

[0041] The bottom wall of the cover body 61 is located between the trigger member 5 and the switch elastic piece of the trigger switch 4. In specific use, when the water level in the water storage chamber 32 rises, the trigger member 5 moves upward and pushes up the bottom wall of the cover body 61, thereby pushing up the switch elastic piece of the trigger switch 4 to activate the trigger switch 4, and the heating member 2 is energized.

[0042] Since the bottom wall of the cover body 61 is thin, the cover body 61 not only seals the trigger switch 4 waterproofly, but also increases the sensitivity of the triggering and cutting of the trigger member 5 relative to the trigger switch 4, making the response of the conduction and cutting of the heating member 2 timely and sensitive, thereby improving the safety of using the humidifier.

[0043] In some embodiments, referring to Figs. 1 to 6, the base 1 is provided with an attachment portion 11 located above the water storage chamber 32 and to which the trigger switch 4 is attached. Referring to Figs. 3 to 6, the attachment portion 11 may include, for example, a switch base 112 and a switch bracket 71. Here, the surface of the switch base 112 facing the water storage chamber 32 has an escape hole, the trigger switch 4 is connected to the inside of the switch base 112 via the switch bracket 71, and the waterproof protective cover 6 is fitted to the outside of the trigger switch 4, passes through the escape hole, and is sealed and disposed in the escape hole in the switch base 112. Note that the upper part of the switch base 112 is covered with a cover plate 111 in a sealed manner, so that the trigger switch 4 is disposed in a relatively sealed space, and the trigger switch 4 can be waterproof-protected to a certain extent.

[0044] 3, the switch bracket 71 may include, for example, two sub-frames disposed opposite to each other and detachably connected to each other, which together define a space for assembling the trigger switch 4. Specifically, an insertion rod is provided on one of the sub-frames, and the trigger switch 4 is provided with an insertion hole into which the insertion rod can be inserted. First, the trigger switch 4 is pre-assembled to one of the sub-frames by fitting the insertion rod into the insertion hole, and then the two sub-frames are connected to each other, thereby assembling the switch bracket 71 and the trigger switch 4. Next, the waterproof protective cover 6 is fitted onto the outside of the switch bracket 71 and the trigger switch 4.

[0045] 4 to 9, in some embodiments, the waterproof protective cover 6 further includes an assembly part 64 provided on the cover body 61 and fitted and connected to the mounting part 11, and the thickness of the assembly part 64 is greater than that of the cover body 61. That is, the trigger switch 4 is actuated by realizing the fitting with the trigger member 5 via the cover body 61, and the waterproof protective cover 6 is assembled by fitting the assembly part 64 with the mounting part 11. At the same time, by making the thickness of the assembly part 64 greater than that of the cover body 61, the strength of the connection position between the waterproof protective cover 6 and the mounting part 11 can be increased to a certain extent, and the waterproof protective cover 6 is prevented from being damaged by pressure during assembly, effectively protecting the waterproof protective cover 6 and enhancing the protective effect of the waterproof protective cover 6 against the trigger switch 4.

[0046] Here, the assembly portion 64 can be molded integrally with the cover body 61, for example, to increase the overall structural strength of the entire waterproof protective cover 6.

[0047] 4 to 9, in some embodiments, the assembly part 64 includes an assembly groove 63, and the mounting part 11 has a protrusion 711, and when the waterproof protective cover 6 is connected to the mounting part 11, the protrusion 711 can be protruded into the assembly groove 63, making the assembly easy and the connection reliable and stable. Here, the protrusion 711 may be provided on the outer wall of the switch bracket 71, for example.

[0048] In some embodiments, the protrusion 711 is sealed into the assembly groove 63, which further improves the waterproof sealing function of the waterproof protective cover 6 for the trigger switch 4, and helps to extend the service life of the humidifier. The sealing function of the waterproof protective cover 6 for the trigger switch 4 can be further improved.

[0049] In some embodiments, referring to Figures 3 to 9, the cover body 61 has an opening 62 on the side away from the trigger member 5, through which at least the trigger switch 4 can enter and through which an assembly portion 64 is provided, thereby facilitating assembly and providing a certain degree of waterproofing.

[0050] 7 to 9, in some embodiments, the assembly groove 63 is an annular assembly groove provided along the circumferential direction of the cover body 61. This improves the uniformity of the force received during assembly, making the assembly easier. In addition, the contact connection area between the switch bracket 71 and the waterproof protective cover 6 is increased, improving the connection strength between the switch bracket 71 and the waterproof protective cover 6.

[0051] Specifically, since the thickness of the groove wall of the assembly groove 63 is thicker than the thickness of the cover body 61, the strength of the connection position between the assembly part 64 and the mounting part 11 is improved, thereby preventing the waterproof protective cover 6 from being damaged by pressure during assembly, effectively protecting the waterproof protective cover 6, and improving the protective effect of the waterproof protective cover 6 against the trigger switch 4.

[0052] 7 to 9, in some embodiments, the groove wall of the assembly groove 63 includes two side groove walls 631 arranged opposite to each other, and the thickness T2 of the two side groove walls 631 is thicker than the thickness of the cover body 61. This improves the connection and fitting strength between the assembly part 64 and the switch bracket 71, improves structural stability, and prevents the waterproof protective cover 6 from being damaged by pressure during assembly.

[0053] 5 and 9, the thickness T2 of the side groove wall 631 is the dimension of the side groove wall 631 in the direction from the trigger member 5 to the trigger switch 4 (see the Z direction in FIGS. 5 and 9).

[0054] The thickness T2 of the two gutter walls 631 is greater than the thickness T1 of the cover body 61, thereby ensuring the sensitivity of the trigger and further preventing the assembled parts from being damaged by pressure during assembly.

[0055] Specifically, the thickness of the two gutter walls is equal, which ensures that the force received by the waterproof protective cover 6 during assembly is uniform, making it less likely to be damaged, and improves the coupling and fitting effect with the switch bracket 71, thereby improving the overall stability.

[0056] 4 to 9, in some embodiments, the mounting portion 11 includes a horizontally disposed support wall 113 and an abutment wall 114 extending from the outer edge of the support wall 113 in a direction away from the water storage chamber 32. Here, a first fitting surface 641 arranged horizontally and a second fitting surface 642 extending from the edge of the first fitting surface 641 in a direction away from the cover body 61 are formed on the outer wall of the assembly portion 64. Specifically, when the waterproof protective cover 6 is connected to the mounting portion 11, the first fitting surface 641 is located on the support wall 113 and is hermetically connected to the support wall 113, and the second fitting surface 642 abuts against the abutment wall 114.

[0057] In other words, when the waterproof protective cover 6 is connected to the mounting portion 11, the first mating surface 641 of the waterproof protective cover 6 is joined to the support wall 113 of the mounting portion 11 by lap jointing, and the abutment wall 114 of the mounting portion 11 is joined to the second mating surface 642 of the waterproof protective cover 6, thereby further improving the sealing function of the mating connection position between the waterproof protective cover 6 and the mounting portion 11 and further improving the protective effect of the waterproof protective cover 6 against the trigger switch 4.

[0058] 4, in some embodiments, the trigger member 5 is a float, and there is a floating gap L between the float and the inner wall of the water storage chamber 32, allowing the float to float up and down. That is, the float located in the water storage chamber 32 and the chamber wall of the water storage chamber 32 are gap-fitted, which can prevent the float from getting caught during rising and falling to some extent, ensure the smooth rising and falling of the float with changes in the water level in the water storage chamber 32, and further improve the timeliness and sensitivity of the control of the trigger switch 4.

[0059] Referring to FIG. 4, the floating gap L can be specifically set between 0.5 mm and 1.5 mm.

[0060] In some embodiments, a guide structure is further provided between the water chamber 32 and the float to guide the float.

[0061] The provision of the guide structure has a guiding effect on the movement of the float in the Z direction within the water tank 31, which not only prevents the float from tilting as it moves toward and away from the waterproof protective cover 6, but also prevents the float from getting caught. This allows the float to effectively push up the waterproof protective cover 6 and accurately trigger the trigger switch 4, improving the sensitivity of the trigger control and improving safety in use.

[0062] In some embodiments, referring to Figures 3 and 6, the guide structure includes a guide groove 81 provided on the side wall of the float and a guide rib 82 provided on the chamber wall of the water storage chamber 32, and the guide rib 82 moves along the guide groove 81 when the float floats up and down.

[0063] The guide structure is configured with a guide groove and a guide rib that fit together, which simplifies the structure and facilitates manufacturing. At the same time, the guide effect is good, and the accuracy of the float that triggers the trigger switch 4 can be improved.

[0064] In some other embodiments, the guide structure may include a guide rib provided on the side wall of the float and a guide groove provided on the chamber wall of the water storage chamber 32.

[0065] 3 and 6, in some embodiments, a bracket 72 is provided in the water storage chamber 32, and the bracket 72 and a part of the chamber wall of the water storage chamber 32 form a lifting chamber. The bracket 72 is provided with a water guide hole 73, through which water in the water storage chamber 32 can enter the lifting chamber, and the float is attached to the lifting chamber and can rise and fall relative to the bracket 72. In a specific embodiment, the guide rib 82 can be provided, for example, on the surface of the bracket 72 facing the float.

[0066] In some embodiments, referring to Figures 3 to 6, the float includes a floating body 51 and a trigger portion 52 provided on the side of the floating body 51 facing the waterproof protective cover 6, and the trigger portion 52 pushes up the waterproof protective cover 6 to trigger the trigger switch 4.

[0067] Here, the trigger portion 52 may be, for example, a convex portion for pushing up the waterproof protective cover 6, which makes it easy to push up and improves the pushing-up effect.

[0068] In some embodiments, an anti-adhesion protrusion is provided on the surface of the float that faces away from the trigger portion 52, and the anti-adhesion protrusion allows the float to resist to some extent the tension of the water in the water chamber 32. This makes it possible to prevent the float from adhering to the inner bottom wall of the water chamber 32 and becoming unable to float up.

[0069] Here, the adhesion prevention protrusions may be composed of a plurality of small protrusions arranged at intervals.

[0070] 1 and 2, in some embodiments, the humidifier further includes a water tank 33 disposed on the base 1, communicating with the water chamber 32 and supplying water into the water chamber 32. When the humidifier includes the spray unit 9, the spray unit 9 is specifically located on one side of the water tank 33.

[0071] Water tub 31 communicates with water tank 33 via water storage chamber 32, allowing water in water tank 33 to flow into water tub 31 via water storage chamber 32. In specific use, heating member 2 heats the water in water tub 31 to create mist, which is then discharged via spray unit 9 to humidify the air.

[0072] Specifically, when the water level in the water storage chamber 32 rises to a first predetermined water level, the trigger switch 4 is actuated and the water tank 33 stops supplying water to the water storage chamber 32. When the water level in the water storage chamber 32 falls to a second predetermined water level, the trigger switch 4 is shut off and the water tank 33 continues supplying water to the water storage chamber 32. Here, the second predetermined water level is lower than the first predetermined water level.

[0073] By automatically supplying water when there is a water shortage in response to changes in the water level in the water storage chamber 32, the normal operation of the humidifier is ensured, the safety and sensitivity of the humidifier in use are improved, and the user's experience is improved.

[0074] For example, when the water level reaches the first predetermined water level or higher, the float pushes up the waterproof protective cover 6 against the elastic force of the switch elastic piece of the trigger switch 4, thereby pushing up the switch elastic piece and triggering the conduction of the trigger switch 4, and the trigger switch 4 controls the heating member 2 to heat the water in the water tank 31 to create mist, and the mist is discharged through the spray unit 9 to humidify the air. When the water level falls below the second predetermined water level, that is, when the water level in the water storage chamber 32 becomes low or there is a water shortage, the upward pushing force received by the switch elastic piece of the trigger switch 4 disappears, the switch elastic piece is restored, the trigger switch 4 is cut off, and the water tank 33 continues to supply water into the water storage chamber 32. For example, when the water level rises to the first predetermined water level with the rise of the water level, the trigger switch 4 is triggered. This improves the safety of the humidifier in use and improves the user's experience.
