[0051] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0052] The present utility model is made based on the inventor's discovery and recognition of the following facts and problems:

[0053] In the related art, when the water tank of the humidifier is lifted, there will still be some remaining water in the water trough of the base. The magnetic float will generate up and down floating displacement under the fluctuation of the water, resulting in the problem that the reed switch repeatedly turns on and off.

[0054] As Figure 1 shown, the switch assembly 100 of the embodiment of the present utility model includes a mounting member 1, a switch body 2, a movable member 3 and an elastic member 4.

[0055] The mounting member 1 can be an injection-molded part, a metal part, etc., and the mounting member 1 can be in a plate-like structure, a block-like structure, etc. When in use, the mounting member 1 mainly serves to provide an assembly position for other components such as the switch body 2 and the movable member 3, which is conducive to realizing the integration and integrity of the layout of the switch assembly 100.

[0056] The switch body 2 is provided on the mounting member 1. For example, as Figure 1 shown, the mounting member 1 can be provided with a hole-like structure, etc., and the switch body 2 can be fixed within the mounting member 1 by means of insertion. In some other embodiments, the switch body 2 can also be fixed to the mounting member 1 by means of snap fixation, fastener fixation, bonding, etc.

[0057] The movable member 3 is movably assembled on the mounting member 1 and has an open position for opening the switch body 2. For example, as Figure 1 shown, a part of the mounting member 1 can extend along the up-and-down direction, and the movable member 3 can be slidably assembled on the part of the mounting member 1 that extends along the up-and-down direction. During the movement of the movable member 3, the movable member 3 and the switch body 2 have the above-mentioned open position, and the open position is the position where the movable member 3 connects the switch body 2, which can be specifically regarded as Figure 1 the position where the movable member 3 is located in . After the switch body 2 is connected, it can satisfy actions such as driving the wind blade, thus meeting the use requirements of the corresponding equipment's execution actions.

[0058] It should be noted that the operation of the movable member 3 to drive the switch body 2 to open can be non-contact, that is, the movable member 3 and the switch body 2 can achieve inductive opening through electromagnetic induction, photoelectric induction, etc.

[0059] In some other embodiments, the operation of the movable member 3 to drive the switch body 2 to open can also be contact-type. That is, during the up-and-down movement of the movable member 3, the movable member 3 can drive a gate-like component on the switch body 2 to act, thus also meeting the use requirements of opening and closing the switch body 2.

[0060] The elastic member 4 acts on the movable member 3, and the elastic member 4 is used to drive the movable member 3 away from the open position when the movable member 3 is released from the limit. For example, as Figure 1 and Figure 2 shown, the elastic member 4 can be a spring. The elastic member 4 can extend along the up-and-down direction, and one end of the elastic member 4 can be connected to the mounting member 1, and the other end of the elastic member 4 can be connected to the movable member 3. When in use, as Figure 1 shown, the movable member 3 can be pressed down by a limiting part 200 and other structural components and limited in the above-mentioned open position, thus meeting the use requirements of the equipment's circuit connection.

[0061] When not in use, the limiting part 200 can be removed. At this time, as Figure 2As shown, the movable member 3 can be pushed upward under the action of the elastic member 4, thereby driving the movable member 3 away from the open position, and further enabling the switch body 2 to be switched to the closed state. Since the elastic member 4 always exerts an upward force on the movable member 3, when the movable member 3 is released from the limiting effect of the limiting portion 200, the elastic member 4 will also prevent the movable member 3 from moving toward the open position, thus avoiding the situation where the switch body 2 is repeatedly powered on and off.

[0062] For the switch assembly 100 according to the embodiment of the present invention, by providing the elastic member 4, the elastic member 4 can drive the movable member 3 away from the open position and prevent it from moving toward the open position, thereby avoiding the situation where the movable member 3 repeatedly moves toward the open position and causes the switch body 2 to be repeatedly powered on and off, and ensuring the stability of the power-off state of the switch assembly 100.

[0063] In some embodiments, the mounting member 1 is provided with a column 11, at least part of the switch body 2 is disposed within the column 11, and the movable member 3 and the elastic member 4 are both disposed on the outer peripheral side of the column 11.

[0064] For example, as Figure 1 shown, the column 11 can be cylindrical and integrally formed on the mounting member 1 by injection molding, and the switch body 2 can be injection-molded and fixed within the column 11. The movable member 3 and the elastic member 4 can both be disposed outside the column 11. For example, a slide rail structure can be provided on the outer side of the column 11, and the movable member 3 can be slidably assembled on the outer side of the column 11 through the slide rail structure, and the elastic member 4 can be located beside the column 11 and arranged in parallel and spaced apart from the column 11.

[0065] Thus, it can play a role in separating the switch body 2 from the movable member 3 and the elastic member 4. At this time, the movable member 3 and the switch body 2 can achieve the switching of the opening and closing actions only by induction. Thereby, it can play a role in protecting the switch body 2 and also achieve the effect of liquid isolation and protection, and further ensure the stability of the use of the switch body 2.

[0066] In some embodiments, a slot 12 is provided within the column 11, and at least part of the switch body 2 is snap-fitted within the slot 12. For example, as Figure 1 and Figure 2 shown, the column 11 can be a hollow structure, and the slot 12 is provided within the column 11 and extends along the extending direction of the column 11. The slot opening of the slot 12 can be provided at the bottom side of the column 11.

[0067] During assembly, the switch body 2 can be directly inserted into the slot 12, and one of the switch body 2 and the mounting member 1 can also be provided with a snap, and the other can be provided with a slot. Through the snap-fit of the snap and the slot, the switch body 2 can be fixed within the slot 12, thus facilitating assembly and also facilitating subsequent disassembly and maintenance.

[0068] In some embodiments, both the movable member 3 and the elastic member 4 are sleeved on the outer peripheral side of the column 11. One end of the elastic member 4 abuts against the movable member 3, and the other end of the elastic member 4 abuts against the mounting member 1.

[0069] For example, as Figure 1 shown, the movable member 3 can be annular, and the elastic member 4 can be a compression spring. During assembly, both the movable member 3 and the elastic member 4 can be sleeved on the outer peripheral side of the column 11 from above the column 11. Among them, the elastic member 4 can be located below the movable member 3, and the top end of the elastic member 4 can abut against the movable member 3, and the bottom end of the elastic member 4 can be between the movable member 3 and the mounting member 1.

[0070] During use, the elastic member 4 can always apply an upward acting force to the movable member 3, so that when the limiting portion 200 releases the downward pressure on the movable member 3, the movable member 3 can be pushed upward, facilitating the driving of the movable member 3 away from the opening position.

[0071] In some other embodiments, the elastic member 4 can also be a tension spring. For example, the elastic member 4 can be arranged on the top side of the movable member 3. When the limiting portion 200 releases the downward pressure limit on the movable member 3, the elastic member 4 will retract and can pull the movable member 3 upward, thereby also driving the movable member 3 away from the opening position.

[0072] In some embodiments, the switch assembly 100 further includes a stop member 5. The stop member 5 is arranged on the column 11, and the stop member 5 is used to stop the movable member 3 to prevent the movable member 3 from detaching from the column 11.

[0073] For example, as Figure 1 and Figure 2 shown, the stop member 5 can be installed at the top end of the column 11. The stop member 5 can be annular and can be sleeved and fixed on the outer peripheral side of the column 11. For example, the stop member 5 can be fixed on the outer peripheral side of the column 11 by means of threaded assembly.

[0074] During use, the stop member 5 can cooperate with the movable member 3 to stop, thereby preventing the movable member 3 from disengaging from the top end of the column 11 and ensuring the stability of the assembly structure when the movable member 3 reciprocates up and down.

[0075] In some embodiments, the column 11 includes a first column section 111 and a second column section 112. The radial dimension of the first column section 111 is smaller than the radial dimension of the second column section 112. The first column section 111 is located at the end of the column 11 away from the mounting member 1, and the stop member 5 is detachably assembled on the outer peripheral side of the first column section 111.

[0076] For example, as Figure 1 and Figure 2As shown, the first column section 111 and the second column section 112 can be integrally formed by injection molding. The first column section 111 can be connected to the top of the second column section 112, and the radial dimension of the first column section 111 is smaller than that of the second column section 112, so that a stepped structure can be formed between the first column section 111 and the second column section 112. The stopper 5 can be sleeved on the outer peripheral side of the first column section 111 and can be stopper-fitted at the stepped structure of the first column section 111 and the second column section 112, thereby playing a role in limiting the assembly of the stopper 5 and also improving the stability of the overall assembly structure.

[0077] In some embodiments, the stopper 5 is provided with a groove 51, and the second column section 112 is inserted and fitted into the groove 51. For example, as Figure 1 and Figure 2 shown, the stopper 5 can be a cap-shaped structure as a whole, and the groove 51 can be provided on the bottom side of the stopper 5. When the stopper 5 is fixed on the outer peripheral side of the first column section 111, the top of the second column section 112 can extend into the groove 51, so as to realize the circumferential limit fit between the second column section 112 and the stopper 5, further improving the structural stability of the assembly.

[0078] In some embodiments, the switch body 2 is a reed switch and the moving part 3 is a magnet.

[0079] The humidifier according to the embodiments of the present invention will be described below.

[0080] The humidifier according to the embodiments of the present invention includes a switch assembly 100, and the switch assembly 100 can be the switch assembly 100 described in any of the above embodiments.

[0081] In some embodiments, as Figure 3 shown, the humidifier includes a base assembly 300 and a water tank assembly 400.

[0082] The base assembly 300 includes a switch assembly 100 and a water tank 303 with an upward opening. The switch assembly 100 is arranged in the water tank 303, and at least part of the water tank 303 forms a mounting member 1. For example, as Figure 4 shown, the base assembly 300 can include a base housing 301 and a chassis 302. The base housing 301 can be cylindrical, and the chassis 302 can be installed on the bottom side of the base housing 301 to seal the bottom of the base housing 301. The water tank 303 can be installed in the base housing 301, and the mouth of the water tank 303 is arranged upward. During use, the water tank 303 is used to store a part of liquid such as water.

[0083] As Figure 6As shown, the switch assembly 100 can be regarded as part of the base assembly 300, where the mounting member 1 of the switch assembly 100 can be regarded as part of the water tank 303 or the water tank 303, that is, the switch body 2, the movable member 3, the elastic member 4, and the stopper 5 of the switch assembly 100 are all assembled at the water tank 303.

[0084] The water tank assembly 400 is detachably mounted above the base assembly 300 and seals the opening of the water tank 303. For example, the water tank assembly 400 may include components such as a water tank housing and a water tank. The water tank is assembled inside the water tank housing, and the water tank is used to store liquids such as water. The water tank assembly 400 can be directly placed above the base assembly 300 and is in plug-in fit with the base assembly 300, thereby improving the convenience of assembling the water tank assembly 400 and the base assembly 300.

[0085] In some embodiments, the water tank assembly 400 includes a limiting portion 200. The movable member 3 is located between the limiting portion 200 and the elastic member 4. The limiting portion 200 is used to abut against the movable member 3 to keep the movable member 3 in the open position.

[0086] For example, as Figure 5 shown, the limiting portion 200 can be a tubular structure, and the limiting portion 200 can be integrally formed on the bottom side of the water tank assembly 400. The inner diameter dimension of the limiting portion 200 is larger than the radial dimension of the column 11. When the water tank assembly 400 is mounted above the base assembly 300, the limiting portion 200 can be located on the outer peripheral side of the column 11, and the bottom side of the limiting portion 200 can abut against the movable member 3, so that the limiting portion 200 can play a role in pressing down the movable member 3 to the open position, ensuring the connectivity of the circuit when the humidifier is in use.

[0087] In some embodiments, the limiting portion 200 is tubular, and the end of the limiting portion 200 facing the movable member 3 is provided with a plurality of slots 201 for discharging the liquid inside the limiting portion 200.

[0088] For example, as Figure 5 shown, the slots 201 can be semi-circular grooves, and the slots 201 can be provided at the bottom of the limiting portion 200 and can be arranged at equal intervals along the circumferential direction of the limiting portion 200. Since the limiting portion 200 is located in the water tank 303 during actual use, due to the action of hydraulic pressure, etc., when the limiting portion 200 is removed from the water tank 303, a part of the liquid such as water is easily retained inside the limiting portion 200, which causes inconvenience in use.

[0089] By providing the slots 201 on the circumferential side of the limiting portion 200, the outflow of the water inside the limiting portion 200 is facilitated, thereby avoiding the problem that water is easily retained inside the limiting portion 200 and also achieving the balance of the hydraulic pressure on both sides inside and outside the limiting portion 200.

[0090] In some embodiments, one of the base assembly 300 and the water tank assembly 400 is provided with a plurality of first plugging portions 3021, and the other is provided with a plurality of second plugging portions 401. The plurality of first plugging portions 3021 are pluggingly engaged with the plurality of second plugging portions 401 in a one-to-one correspondence.

[0091] For example, as Figure 4 shown, the first plugging portions 3021 can be integrally formed on the top side of the chassis 302. The first plugging portions 3021 can be columnar structures and there can be three of them. The three first plugging portions 3021 can be arranged at intervals along the circumferential direction of the chassis 302. The second plugging portions 401 can be integrally formed on the bottom side of the water tank assembly 400. The second plugging portions 401 can be circular tube structures and there can also be three of them. The three second plugging portions 401 can be arranged at intervals along the circumferential direction of the water tank assembly 400.

[0092] When assembling the water tank assembly 400 and the base assembly 300, the three first plugging portions 3021 can be pluggingly assembled into the three second plugging portions 401 in a one-to-one correspondence. Thus, on the one hand, it can achieve the effect of assembly positioning, ensuring the assembly accuracy of the water tank assembly 400 and the base assembly 300. On the other hand, it can also improve the limiting effect, ensuring the structural stability of the assembly of the two.

[0093] In some embodiments, as Figure 4 shown, the base assembly 300 can further include a float 305 and a float bracket 304. The float bracket 304 can be installed in the base housing 301 through fasteners, and the float 305 can be rotatably assembled on the float bracket 304. In use, the float 305 can rotate under the gravity of the water in the water tank assembly 400, and then can drive the opening of a valve or the like between the water tank assembly 400 and the water trough 303, thus facilitating the transportation of liquids such as water in the water tank assembly 400 to the water trough 303.

[0094] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present invention.
