Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus consistent with certain aspects of the present invention, as detailed in the attached application.

In an embodiment of the present disclosure, as shown in fig. 1 and 2, a humidifier 10 is provided, including:

a case 11 and a base 12; the box body 11 is positioned above the base 12; the box body 11 is provided with an accommodating cavity 111;

a graduated scale 13 positioned on the wall of the box body 11;

a light emitting module 14 located in the base 12 and having at least a portion facing the scale 13; wherein a lens 15 is arranged between the part facing the scale 13 and the scale 13, and the lens 15 is connected with the scale 13.

In the embodiment of the present disclosure, the accommodating chamber 111 of the humidifier 10 may contain a liquid, which includes but is not limited to: water, disinfectant, etc.

Here, the liquid is transparent or translucent. The liquid may also be a mixed liquid in which an air freshener and water are mixed.

In some embodiments, the box 11 is located on the base 12, and the box 11 is connected to the base 12, and the base 12 has a certain supporting force for supporting the box 11 and the liquid stored in the accommodating cavity 111 of the box 11.

Here, the total weight of the case 11 and the liquid stored in the accommodating chamber 111 does not exceed the weight that can be supported by the base 12. And an upper limit of the level of liquid in the receiving chamber 111 may be defined, for example not to exceed a certain number of graduations in the scale 13,

thereby reducing the probability of excess liquid leading to excess weight.

In some embodiments, the scale 13 is located in the accommodating cavity 111, so that the liquid level of the liquid in the accommodating cavity 111 can be measured, and a user can read and determine the water level in the accommodating cavity 111 conveniently.

In some embodiments, the light module 14 is located in the base 12 and thus below the accommodating cavity 111 of the box 11, so that light can be emitted from the bottom of the accommodating cavity 111 into the accommodating cavity 111, and the light module 14 can illuminate part of the liquid. Because the refractive indexes of the light in the air and the liquid are different, when the light is emitted upwards from the bottom of the liquid, a more obvious liquid level line can be formed at the intersection of the liquid and the air.

In this way, the liquid level line can be more clearly displayed on the scale 13.

In some embodiments, since the light module 14 has at least a portion facing the scale 13, the light emitted from the light module 14 can at least partially illuminate the scale 13. Thereby improving the accuracy of reading the liquid level line through the scale 13.

In this way, no matter in which environment, even in a dark environment, such as evening or night, the user can read the liquid level line more accurately through the scale with certain light. Thereby improving the accuracy of reading the liquid level line.

In the embodiment of the present disclosure, as shown in fig. 1 and fig. 2, the humidifier 10 further includes:

and the lens 15 is positioned in the accommodating cavity 111 between the light-emitting module 14 and the graduated scale 13.

In the embodiment of the present disclosure, the lens may be a concave lens having a light diverging function, and when parallel light rays are deflected by the concave spherical lens, the light rays diverge, which is called divergent light rays.

Here, the concave lens may be a convex-concave lens, i.e., a convex-concave lens. The concave surface is the one side that absorbs parallel light, and the convex surface is the one side that diverges light. The material of the lens can be glass or plastic.

The lens 15 is opposite to the light emitting module 14, and can absorb the parallel light emitted by the light emitting module 14.

In one embodiment, the lens 15 is attached to the scale 13, which allows the lens 15 to direct a portion of the absorbed light directly into the scale 13. And at least a portion of the lens 15 may be a portion of the bottom of the accommodating chamber 111, and the lens 15 may transmit the absorbed light into the accommodating chamber when the liquid is stored in the accommodating chamber 111.

In specific implementation, since the lens 15 is located between the light emitting module 14 and the scale 13, when the light emitting module 14 emits light, the lens 15 can transmit the light emitted by the light emitting module 14 to the scale 13 and the accommodating cavity 111.

In this way, by means of the lens 15, the transmission of light from the light emitting module 14 to the scale 13 and the accommodating cavity 111 is realized.

As shown in connection with fig. 1 and 2, in the disclosed embodiment,

the convex surface 151 of the lens 15 faces the direction of the scale 13;

the concave surface 152 of the lens 15 faces the direction of the light emitting module 14.

In the embodiment of the present disclosure, the concave surface 152 of the lens 15 faces the direction of the light emitting module 14, and when the light emitting module 14 emits light to the concave surface 152, the light is refracted on the concave surface 152. When light further passes from the inside of the lens 15 to the convex surface 151, the light is scattered at the convex surface 151, so that the light is diffused through the periphery of the convex surface 151.

Here, since the convex surface 151 of the lens 15 faces the direction of the scale 13, a part of the light is transmitted to the scale 13, thereby illuminating the scale 13.

In one embodiment, a portion of the convex surface 151 of the lens 15 faces the accommodating cavity 111, so that the liquid stored in the accommodating cavity 111 can be illuminated. Further, again due to the different refractive indices of light in the liquid and in the gas, when light travels within the liquid and reaches the liquid surface, the light is refracted again at a different angle of refraction. This results in a more pronounced boundary between air and liquid, facilitating the determination of the liquid level line.

In this way, the absorption of the light is achieved by the concave surface 152 of the lens 15 and the divergence of the light is achieved by the convex surface 151. Thereby, the liquid level line is more obvious and the graduated scale 13 has brightness, which is convenient for reading the liquid level line in a darker environment.

As shown in fig. 1 and 2, in the disclosed embodiment,

the scale 13 is integrally formed with the lens 15.

In the embodiment of the present disclosure, if the material of the scale 13 and the lens 15 is glass, the scale 13 and the lens 15 may be integrally formed by molding or blowing.

For another example, if the material of the scale 13 and the lens 15 is plastic, the scale and the lens 15 may be integrally molded by plastic casting, injection molding, or the like.

Thus, the graduated scale 13 and the lens 15 are integrally formed, so that the process cost can be saved, and the installation is convenient.

Referring to fig. 1 and fig. 2, in the embodiment of the present disclosure, the light emitting module 14 includes:

a light source 141;

a first end 1421 of the light guide part 142 is opposite to the light source 141, and a second end 1422 of the light guide part 142 is opposite to the concave surface 152 of the lens 15.

In the embodiment of the present disclosure, the light source 141 is disposed on the first base bracket 121 in the base 12. The first base support 121 is connected to a base housing 122 of the base 12. The light guide portion 142 is connected to the base case 122. A second base bracket 123 is disposed at one side of the light guide part 142, and the second base bracket 123 is attached to one side of the light guide part 142.

As shown in fig. 2, the first base bracket 121, the portion of the base housing 122, the second base bracket 123 and the lens 15 form a relatively closed space for accommodating the light emitting module 14. The first base support 121, part of the base housing 122 and the second base support 123 are opaque, and only the lens 15 has light transmittance.

Here, the light guide part 142 may be a light guide pillar, and the shape of the light guide pillar includes, but is not limited to: a tapered column. The tapered rod may be larger in size at an end near the light source 141 than the tapered rod is near the lens 15. The shape of the second base support 123 follows the shape of part of the light guide column, thereby surrounding the light guide column together with a portion of the base housing 122.

In a specific implementation, since the first end 1421 of the light guide part 142 is associated with the light source 141, the light guide part 142 can absorb the light emitted from the light source 141. When the light of the light source 141 is input into the light guide pillar, total reflection occurs inside the light guide pillar with respect to the light. The second end 1422 of the light guide portion 142 is opposite to the concave surface 152 of the lens 15, and when the light is on the side of the light guide pillar near the lens 15 and the scale, the light is converged and output to the concave surface 152 of the lens 15.

Therefore, the light of the light emitting module 14 is mainly emitted through the lens 15, and the emission of the light to the periphery of the light guide pillar of the light emitting module 14 is reduced.

In the embodiment of the present disclosure, as shown in fig. 1 and 2, the light source 141 includes an LED.

In the embodiment of the disclosure, because the LED releases energy by recombination of electrons and holes, electric energy can be efficiently converted into light energy, and the display response speed is fast.

In other embodiments, the light source 141 may further include, but is not limited to, one or a combination of the following:

photoluminescent materials, such as fluorescent materials;

electroluminescent materials, such as light emitting nixie tubes.

In this way, the light source 141 may provide a richer variety of lighting types.

In the embodiment of the present disclosure, as shown in fig. 1 and fig. 2, the light source 141 is connected to the control circuit 124 in the base 12;

the control circuit 124 is connected to a power source (not shown).

In the embodiment of the present disclosure, a switch is disposed in the control circuit 124, and when the switch is closed, the control circuit 124 is turned on to enable the power supply to provide power to the light source 141, so that the light source 141 emits light.

Here, an acoustic sensor (not shown) may be further provided in the base 12, and the acoustic sensor is connected to the switch. When the sound sensor detects sound approaching the humidifier, the switch is closed, the control circuit 124 is turned on, and the light source 141 is controlled to emit light.

For another example, a light sensor (not shown) may be disposed in the base 12, and the light sensor is connected to the switch. When the light sensor detects that the environment outside the humidifier 10 is dim or dark, the switch is closed, the control circuit 124 is turned on, and the light source 141 is controlled to emit light.

Of course, both the sound sensor and the light sensor may be in communication with the switch, and the light source 141 may be controlled to emit light only when it is in the dark and a sound is detected. In this way, the light source 141 can be controlled to emit light according to the actual conditions of the outside world, and electric energy can be saved.

In the embodiment of the present disclosure, as shown in fig. 1 and fig. 2, the inner surface of the accommodating cavity 111 has a positioning pin 112;

the graduated scale 13 is provided with a positioning hole 131;

the positioning hole 131 is buckled with the positioning pin 112.

In some embodiments, the size of the locating pin 112 may be larger than the size of the locating hole 131, thereby achieving an interference fit.

Here, the shape of the positioning pin 112 corresponds to the shape of the positioning hole 131. The shape of the positioning pin 112 includes, but is not limited to, one or a combination of the following:

a circular shape;

an oval shape;

and (4) square.

In the embodiment of the present disclosure, the scale 13 is firmly connected to the positioning pin 112 of the accommodating cavity 111 through the positioning hole 131.

Furthermore, an adhesive may be coated on the fastening position of the positioning hole 131 and the positioning pin 112, so that the connection between the positioning hole 131 and the positioning pin 112 is more secure and reliable.

In the embodiment of the present disclosure, as shown in fig. 1 and 2, the scale 13 has a light-transmitting region 132; the scale of the scale 13 is disposed in the light-transmitting region 132.

In the embodiment of the present disclosure, the light-transmitting area 132 of the scale 13 is in contact with the liquid in the accommodating chamber 111, and the liquid level of the liquid in the accommodating chamber 111 can be determined through the light-transmitting area 132 on the outer side of the humidifier 10.

Here, the light-transmitting region 132 extends from a junction of the scale 13 and the lens 15 to the other end of the scale 13 away from the lens 15.

In some embodiments, the light-transmitting region 132 can be a transparent illuminable region that can absorb light emitted from the lens 15.

In this way, the light-transmitting area 132 is provided with scales, and is transparent and capable of emitting light, so that the liquid level line inside the accommodating cavity 111 can be determined through the scales on the light-transmitting area 132.

Illustratively, the scale may be of a fully transparent construction, such that each region of the scale is a light-transmissive region.

Further exemplary, the scale may also be a partially transparent structure, with the light transmitting areas being formed only in the transparent portions.

The scale value is located in the light-transmitting area.

In some embodiments, a submersible pump 114 is disposed in the tank 11, the submersible pump 114 being configured to deliver water from the receiving chamber 111 to a water supply line 115, the water supply line 115 delivering the water flow to the filter cartridge assembly 40 to wet the filter paper 16 within the filter cartridge assembly 40. Thus, the aim of humidifying the air can be achieved. Here, since the scale 13 in the humidifier 10 has the light-transmitting region 132, and the scale 13 is connected to the lens 15, the lens 15 is opposite to the light emitting module 14. So that the light emitted from the light emitting module 14 can illuminate the scale 13, and the liquid level in the accommodating cavity 111 can be conveniently read. The accuracy of reading is improved.
