[0020] The present application provides a humidifier 10, such as Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 is a forward schematic diagram of an embodiment of a humidifier of the present application; Figure 2 yes Figure 1 A-direction cross-sectional schematic diagram of the medium humidifier; Figure 3 It is an exploded schematic diagram of the first shell of the humidifier of the present application and the main components arranged on the first shell. Among them, the humidifier 10 includes a shell assembly 100, a processing circuit 200 and a liquid level detection assembly 20. The shell assembly 100 is provided with an atomization tank 1021 for accommodating the liquid to be atomized; the processing circuit 200 is arranged outside the atomization tank 1021. The liquid level detection assembly 20 includes: a first sensing element 300 and a second sensing element 400. The first sensing element 300 is arranged in the atomization tank 1021, and the first sensing element 300 is floated on the liquid to be atomized; the second sensing element 400 is arranged on the side of the shell assembly 100 away from the atomization tank 1021, and the first sensing element 300 and the second sensing element 400 are arranged opposite to each other; the processing circuit 200 is connected to the second sensing element 400.

[0021] The first sensing element 300 is inductively connected to the second sensing element 400, and the processing circuit 200 determines the liquid level of the liquid to be atomized in the atomization groove 1021 based on the sensing signal of the second sensing element 400. The liquid to be atomized includes liquids with a humid environment such as water.

[0022] Specifically, in the present embodiment, the liquid level detection assembly 20 of the humidifier 10 includes a first sensing element 300 and a second sensing element 400. Among them, the first sensing element 300 is an element that does not need to be electrically connected to the processing circuit 200 and can make the second sensing element 400 generate a sensing signal, such as a magnetic element such as a magnet. The second sensing element 400 is a device that can sense the first sensing element 300 and generate a sensing signal. The first sensing element 300 and the second sensing element 400 are arranged opposite to each other, and it can be understood that the projections of the first sensing element 300 and the second sensing element 400 along the depth direction X of the liquid to be atomized partially overlap, based on which it can effectively ensure that the first sensing element 300 and the second sensing element 400 can be stably inductively connected. Preferably, the projections of the first sensing element 300 and the second sensing element 400 along the depth direction X completely overlap. Among them, the processing circuit 200 determines the liquid level of the liquid to be atomized in the atomizing tank 1021 based on the sensing signal of the second sensing element 400. It can be understood that when the relative distance between the first sensing element 300 and the second sensing element 400 reaches a preset distance, the second sensing element 400 is inductively connected with the first sensing element 300 and generates a sensing signal. The processing circuit 200 determines the liquid level of the liquid to be atomized in the atomizing tank 1021 based on the sensing signal, thereby controlling the humidifier 10 to perform corresponding work. For example, in this embodiment, the first sensing element 300 is a magnetic component, and the second sensing element 400 is a reed switch. Among them, the reed switch is connected to the processing circuit 200, and the magnetic component is floated on the liquid to be atomized in the atomization tank 1021. When the liquid to be atomized in the atomization tank 1021 reaches the bottom, the relative distance between the reed switch and the magnetic component reaches a preset distance, and the reed switch is inductively connected to the magnetic component. Based on this, the reed switch generates an induction signal and sends it to the processing circuit 200. The processing circuit 200 determines that the liquid to be atomized in the atomization tank 1021 has reached the bottom based on the induction signal, and then controls the humidifier 10 to stop working and issue a water shortage alarm. Optionally, in other embodiments, the first sensing element 300 and the second sensing element 400 may also be other types of sensing elements, and the first sensing element 300 and the second sensing element 400 are continuously inductively connected, based on which the second sensing element 400 continuously outputs a sensing signal, wherein, as the liquid level of the liquid to be atomized changes, that is, the distance between the first sensing element 300 and the second sensing element 400 changes, the second sensing element 400 can output a corresponding sensing signal, based on which the processing circuit 200 can calculate the liquid level of the liquid to be atomized in the atomization tank 1021 according to the corresponding sensing signal, so that the processing circuit 200 can control the humidifier 10 to perform corresponding work according to the change in the liquid level of the liquid to be atomized in the atomization tank 1021.

[0023] Furthermore, in the present embodiment, the first sensing element 300 is disposed in the atomizing groove 1021 and floats on the liquid to be atomized, and the second sensing element 400 connected to the processing circuit 200 is disposed on the side of the shell assembly 100 away from the atomizing groove 1021. Based on this, on the one hand, it can effectively prevent the liquid to be atomized from causing short circuits to the second sensing element 400, and effectively improve the stability of the liquid level detection assembly 20. On the other hand, it can also effectively simplify the structure of the atomizing groove 1021, for example, reducing the protection of the second sensing element 400 and the fixed groove wall, etc., thereby effectively improving the cleaning efficiency and cleanliness of the atomizing groove 1021, and then effectively improving the cleaning efficiency of the humidifier 10.

[0024] Optionally, the processing circuit 200 is an integrated circuit board having the above functions, wherein the second sensing element 400 is integrated on the integrated circuit board.

[0025] Alternatively, if Figure 2 and Figure 3 As shown, the humidifier 10 further includes a float 500. The float 500 is disposed in the atomizing tank 1021, wherein the first sensing element 300 is fixedly connected to the float 500.

[0026] Specifically, in the present embodiment, a float 500 is further provided in the atomizing tank 1021 of the humidifier 10, wherein the first end of the float 500 is rotatably connected to the tank wall of the atomizing tank 1021, and the second end of the float 500 is provided with a receiving tank for accommodating the first sensing element 300. Based on this, the first sensing element 300 is provided on the float 500, which can effectively ensure that when the first sensing element 300 moves relative to the second sensing element 400 with the liquid level of the liquid to be atomized, the projection of the first sensing element 300 along the depth direction X always overlaps with the second sensing element 400, thereby effectively ensuring a stable inductive connection between the first sensing element 300 and the second sensing element 400. For example, in the present embodiment, the first sensing element 300 is a magnetic member, and the second sensing element 400 is a reed switch. When the float abuts against the bottom of the atomizing tank 1021, the magnetic member is inductively connected to the reed switch, so that the reed switch generates an inductive signal.

[0027] Alternatively, if Figure 2 and Figure 3As shown, the float 500 is provided with an atomizing hole 501, and the humidifier 10 also includes an atomizing mechanism 700, wherein the atomizing mechanism 700 is arranged at the bottom of the atomizing groove 1021, and is used to atomize the liquid to be atomized. Among them, the atomizing hole 501 is coaxially arranged with the atomizing mechanism 700. Based on this, the liquid to be atomized in the atomizing groove 1021 can be quickly atomized by the atomizing mechanism 700 to form mist, and the mist can be efficiently guided along the atomizing hole 501, thereby effectively improving the atomization efficiency of the humidifier 10, and the atomizing hole 501 and the atomizing mechanism 700 are coaxially arranged to effectively simplify the flow path of the mist in the atomizing groove 1021, thereby effectively reducing the proportion of liquid carried in the mist.

[0028] Alternatively, if Figure 2 As shown, the housing assembly 100 is also provided with a mist outlet channel 1011 connecting the external space and the atomizing groove 1021, wherein the channel wall of the mist outlet channel 1011 close to one end of the atomizing groove 1021, the projection of which on the float 500 is located outside the atomizing hole 501. Specifically, after the mist flows out of the atomizing groove 1021 along the atomizing hole 501, it further flows out to the external space along the mist outlet channel 1011, wherein the channel wall of the mist outlet channel 1011 close to one end of the atomizing groove 1021 (that is, the channel wall at the entrance of the mist outlet channel 1011), the projection of which on the float 500 is located outside the atomizing hole 501, based on which the liquid filtered in the mist outlet channel 1011 will not directly pass through the atomizing hole 501 and drip on the liquid surface of the liquid to be atomized when it flows back along the channel wall of the mist outlet channel 1011, thereby effectively reducing the noise of the humidifier 10.

[0029] Optionally, in this embodiment, the atomization hole 501 and the drainage hole are staggered along the vertical direction Y of the depth direction X of the liquid to be atomized. Specifically, the float 500 is provided with the atomization hole 501, and most of the liquid to be atomized in the atomization groove 1021 will float out along the atomization hole 501 after atomization, wherein the atomization hole 501 is staggered with the drainage hole along the vertical direction Y of the depth direction X of the liquid to be atomized, based on which the amount of liquid carried in the atomized liquid to be atomized can be effectively reduced.

[0030] Optionally, in this embodiment, the planar shape of the float 500 is the same as the planar shape of the notch of the atomization groove 1021 , and they are proportionally reduced.

[0031] Alternatively, if Figure 2As shown, the float 500 is provided with a receiving groove, and the humidifier 10 also includes: a sealing member 800 and a connecting member (not shown). The sealing member 800 is provided at the notch of the receiving groove, and is used to seal the first sensing element 300 in the receiving groove; the connecting member is provided between the receiving groove and the first sensing element 300, and is used to fix the first sensing element 300 in the receiving groove. Specifically, after the first sensing element 300 is loaded into the receiving groove, the connection relationship between the first sensing element 300 and the receiving groove is reinforced by the connecting member to prevent the first sensing element 300 from shaking in the receiving groove and generating vibration noise. After the first sensing element 300 is fixedly connected to the receiving groove in the above manner, the first sensing element 300 is further sealed in the receiving groove by the sealing member 800, based on which the corrosion of the first sensing element 300 by the liquid to be atomized can be effectively prevented. Among them, the connecting member can be a component with a connecting function such as dispensing.

[0032] Optionally, in some embodiments, the float 500 is detachably rotatably connected to the atomization tank 1021 , based on which when cleaning the atomization tank 1021 , the float 500 can be removed before cleaning the atomization tank 1021 , thereby effectively improving the cleaning efficiency of the atomization tank 1021 .

[0033] Optionally, the shell assembly 100 includes a first shell 102 and a second shell 101 which are spliced ​​to each other, the atomization groove 1021 is arranged on the first shell 102, the mist outlet channel 1011 is arranged on the second shell 101, and the second shell 101 is provided with a liquid storage tank 1012 which is selectively connected to the atomization groove 1021, and the liquid storage tank 1012 is used to store the liquid to be atomized; wherein, the liquid storage tank 1012 is provided with a drainage hole (not marked in the figure), and the projection of the float 500 on the second shell 101 covers the drainage hole.

[0034] Specifically, in this embodiment, the shell assembly 100 is formed by splicing a first shell 102 and a second shell 101, wherein the atomization groove 1021 is arranged on the first shell 102, and the second shell 101 is provided with a liquid storage tank 1012 selectively connected to the atomization groove 1021, and the liquid storage tank 1012 is used to store liquid to be atomized, wherein when the liquid level of the liquid to be atomized in the atomization groove 1021 drops, the drainage hole will connect the liquid storage tank 1012 with the atomization groove 1021, so that the liquid to be atomized in the liquid storage tank 1012 is replenished into the atomization groove 1021 along the drainage hole. Furthermore, the projection of the float 500 on the second shell 101 covers the drainage hole, based on which the liquid to be atomized flowing out of the liquid storage tank 1012 can drip onto the float 500 and then flow into the atomization groove 1021 along the gap between the float 500 and the atomization groove 1021 and the float 500, thereby avoiding the liquid to be atomized flowing out of the liquid storage tank 1012 directly dripping onto the liquid to be atomized in the atomization groove 1021 to cause a large noise, thereby effectively reducing the noise of the humidifier 10.

[0035] Alternatively, if Figure 2 As shown, the side wall of the drainage hole extends to the plane where the notch of the atomizing groove 1021 of the float 500 is located, based on which the kinetic energy of the liquid to be atomized can be effectively reduced, thereby effectively reducing the noise of the humidifier 10.

[0036] Alternatively, if Figure 2 As shown, the projection of the first end of the float 500 on the second housing 101 covers the drainage hole. Specifically, in this embodiment, the first end of the float 500 is an end rotatably connected to the atomizing groove 1021, and its distance relative to the second housing 101 along the depth direction X remains unchanged, based on which the height between the liquid to be atomized in the liquid storage tank 1012 and the float 500 is not affected by the liquid level in the atomizing groove 1021, thereby effectively reducing the noise when the liquid to be atomized drips.

[0037] Alternatively, if Figure 2 and Figure 3 As shown, the humidifier 10 further includes a switch assembly 600, which is disposed between the liquid storage tank 1012 and the atomizing tank 1021, and is used to selectively control the drainage hole to connect the liquid storage tank 1012 and the atomizing tank 1021. Specifically, in this embodiment, by disposing the switch assembly 600 between the liquid storage tank 1012 and the atomizing tank 1021, the drainage hole can selectively connect the liquid storage tank 1012 and the atomizing tank 1021, based on which the liquid to be atomized in the liquid storage tank 1012 is added to the atomizing tank 1021 only when needed, so as to prevent the liquid to be atomized in the atomizing tank 1021 from overflowing.

[0038] Alternatively, if Figure 2 and Figure 3 As shown, the switch assembly 600 includes: a switch valve 601, a reset member 602 and a push member 603. The switch valve 601 is provided with a sealing portion and a push column, the sealing portion is connected to the push column, and the sealing portion is arranged in the liquid storage tank 1012; the reset member 602 is sleeved on the outer peripheral side of the push column, one end of which is abutted against the side of the second shell 101 close to the atomization groove 1021, and the other end is abutted against the end of the push column away from the sealing portion; the push member 603 is arranged opposite to the push column, and is abutted against the end of the push column away from the sealing portion, wherein the push member 603 is used to push the switch valve 601 with the liquid level of the liquid to be atomized in the atomization groove 1021 to make the drainage hole connect the liquid storage tank 1012 and the atomization groove 1021.

[0039] Specifically, in this embodiment, the switch assembly 600 is composed of a switch valve 601, a reset member 602 and a push member 603. The push member 603 is arranged opposite to the push column and abuts against the push column, and the push member 603 rises and falls with the rise and fall of the liquid level of the liquid to be atomized in the atomizing tank 1021. For example, when the liquid level of the liquid to be atomized in the atomizing tank 1021 drops, the push member 603 abuts against the push column to push the sealing part away from the internal opening of the drainage hole, so that the drainage hole connects the liquid storage tank 1012 and the atomizing tank 1021, thereby realizing the above-mentioned function of replenishing the liquid to be atomized in the atomizing tank 1021. For another example, when the liquid level of the liquid to be atomized in the atomization groove 1021 rises, the push-up member 603 descends along the depth direction X, so that the reset member 602 can slowly push the switch valve 601 to reset along the depth direction X (that is, as the liquid level of the liquid to be atomized rises, under the action of the reset member 602, the sealing part of the switch valve 601 slowly approaches the internal orifice of the drainage hole, until the liquid to be atomized fills the atomization groove, and the sealing part of the switch valve 601 completely blocks the internal orifice of the drainage hole), and when the liquid to be atomized fills the atomization groove, the sealing part of the switch valve 601 completely blocks the internal orifice of the drainage hole, thereby stopping the replenishment of the liquid to be atomized into the atomization groove 1021.

[0040] Optionally, a fixed portion is provided at a position of the float 500 relative to the abutting column, and the abutting member 603 is provided at the fixed portion. Specifically, in the present embodiment, the float 500 includes a first end and a second end provided mutually, the first sensing element 1001 is provided at the first end of the float 500, and the position of the float 500 relative to the abutting column is the second end of the float 500, wherein the float 500 is rotatably connected to the groove wall of the atomizing groove 1021, and the rotation axis of the float 500 and the atomizing groove 1021 relative to each other is located between the first end and the second end thereof, and the weight of the first end of the float 500 is greater than the weight of the second end of the float 500, based on which when the liquid to be atomized in the atomizing groove 1021 drops, the position of the float 500 relative to the abutting column will tilt up, thereby lifting the abutting member 603, and further connecting the drainage hole to the liquid storage tank 1012 and the atomizing groove 1021.

[0041] In other embodiments, the switch assembly 600 can achieve selective communication between the atomization groove 1021 and the liquid storage tank 1012 through other structural methods, which will not be described in detail herein.

[0042] Optionally, the humidifier 10 also includes a plurality of air outlet mechanisms (not shown), and an air outlet channel (not shown) is provided on the first shell 102. Specifically, in the present embodiment, the air outlet mechanism includes a driving member such as a blower having a blowing function. The humidifier 10 is provided with a plurality of air outlet mechanisms, and the plurality of air outlet mechanisms are connected to the mist outlet channel 1011 and the atomizing slot 1021 through the air outlet channel. Based on this, the plurality of air outlet mechanisms simultaneously provide power for the mist, so that the mist can obtain greater kinetic energy, effectively improving the height and range of the mist blown out along the mist outlet channel 1011 to the external space, thereby effectively improving the diffusion efficiency and diffusion range of the mist in the external space, thereby effectively improving the humidification range and humidification efficiency of the humidifier 10.

[0043] Optionally, the shell assembly 100 also includes a third shell 103, which is arranged on the side of the first shell 102 away from the second shell 101 and is connected to the first shell 102. A accommodating space for accommodating main circuit components of the humidifier 10, such as the processing circuit 200, the control circuit, the atomization mechanism 700, the second sensing element 400, the air outlet mechanism and other components is formed between the first shell 102 and the third shell 103.

[0044] In summary, the humidifier 10 includes a housing assembly 100, a processing circuit 200 and a liquid level detection assembly 20. The housing assembly 100 is provided with an atomization tank 1021 for accommodating the liquid to be atomized; the processing circuit 200 is arranged outside the atomization tank 1021. The liquid level detection assembly 20 includes: a first sensing element 300 and a second sensing element 400.
