Description

Technical Field

[0001] The present invention relates to the technical field of air treatment, and particularly relates to an air purification humidifier. Background Art

[0002] With the continuous improvement of living standards, people pay more and more attention to the indoor air quality. In order to create a good living environment and improve the indoor air quality, people usually purchase various electrical appliances that can improve the air quality. For example, people will purchase a humidifier to adjust the indoor humidity and a purifier to adjust the indoor air quality. However, in this way, various electrical appliances will be placed at home, which not only increases the purchase cost but also occupies a large amount of indoor space.

[0003] Therefore, some devices that integrate purification and humidification, such as purification humidifiers, have emerged on the market in order to solve the above problems. However, in order to achieve the integration of the two functions, the current integrated purification humidifiers only simply piece together the purifier and the humidifier in terms of structure. Therefore, the following contradictions will emerge: if you want to achieve the same effective area as a single purifier or humidifier, the volume of the integrated purification humidifier will be made very large, resulting in inconvenient movement and use; on the contrary, if you want to reduce the volume, there will be problems with limited purification and humidification effects. That is to say, the existing integrated purification humidifiers have problems in that they cannot balance the device volume and the purification and humidification effects.

[0004] Correspondingly, there is a need in the art for a new air purification humidifier to solve the above problems. Summary of the Invention

The purification and humidification unit includes a cylindrical housing, and a humidification component, a filtering component and a fan nested from outside to inside along the radial direction of the housing.

[0027] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. For example, although the supporting part and the housing in the drawings are integrally formed structures, this connection relationship is not immutable. Those skilled in the art can adjust it according to needs to adapt to specific application scenarios. For example, the connection relationship between the two can also be snap connection, screw connection, welding or bonding, etc.

[0028] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] First, refer to Figures 1 to 3 , to introduce the air purification and humidifier of the present invention. Among them, Figure 1 is the front view of the air purification and humidifier of the present invention; Figure 2 is the sectional view of the air purification and humidifier of the present invention; Figure 3Explosion diagram of the air purification humidifier of the present invention.

[0031] As Figure 1 shown, to solve the problem that the purification humidifier in the prior art cannot balance volume and effect, the air purification humidifier of the present invention mainly includes a base body 1 and a purification and humidification unit 3 connected to the base body 1. The purification and humidification unit 3 includes a cylindrical housing 31, a humidification assembly 32, a filtration assembly 33, and a fan 34 nested in sequence from outside to inside along the radial direction of the housing 31. The axial direction of the housing 31 is generally horizontal, and a first air inlet grille 311 and a second air inlet grille 312 are respectively provided at both ends thereof, and a circumferential air grille 313 is provided on its circumferential direction. The humidification assembly 32 stores a humidification liquid (such as pure water), and the humidification assembly 32 can generate water mist.

[0032] When the air humidification purifier is working, the fan 34 rotates at a high speed, and the indoor air is introduced into the housing 31 along the axial direction of the housing 31 through the first air inlet grille 311 and the second air inlet grille 312, and then is thrown out along the radial direction of the housing 31 under the action of the fan 34. After being filtered by the filtration assembly 33, it is discharged together with the water mist generated by the humidification assembly 32 through the circumferential air grille 313.

[0033] Through the above setting method, the air purification humidifier of the present invention balances the volume and effect of the device while satisfying the purification and humidification functions, greatly improving the user experience. Specifically, through repeated experiments, observations, analyses, and comparisons by the inventor, by nesting the humidification assembly 32, the filtration assembly 33, and the fan 34 in the housing 31 along the radial direction of the housing 31, the purification humidifier of the present invention can greatly reduce the volume of the purification humidifier while achieving the same humidification and purification effects, making the handling and movement of the purification humidifier very convenient. By providing the first air inlet grille 311 and the second air inlet grille 312 at both ends of the housing 31 and the circumferential air grille 313 on the circumferential direction of the housing 31, the air intake volume of the fan 34 is greatly increased, and the indoor air is discharged along the circumferential air grille 313, which also enables the purification humidifier of the present invention to greatly increase the purification and humidification area of action and improve the working efficiency of the purification humidifier.

[0034] Next, further refer to Figures 1 to 5B , and further describe the air purification humidifier of the present invention. Among them, Figure 4 is the structural diagram of the fan blade of the air purification humidifier of the present invention; Figure 5A is the top view of the water tank of the air purification humidifier of the present invention; Figure 5B is the axonometric view of the water tank of the air purification humidifier of the present invention.

[0035] As Figure 1As shown, in a preferred embodiment, the base body 1 includes a base 11, a lifting part 12, and a supporting part 13. The base 11 is connected to the supporting part 13 through the lifting part 12, and the supporting part 13 is connected to the purification and humidification unit 3. Among them, a plurality of rolling members 111, such as universal wheels, are provided below the base 11. The lifting part 12 is a hydraulic lifting mechanism. The supporting part 13 is integrally formed with the housing 31, and an electric control component (not shown in the figure) is provided in the supporting part 13. The electric control component is used to control the start and stop of the fan 34 and / or the rise and fall of the hydraulic lifting mechanism.

[0036] Such as Figures 2 to 4 As shown, the fan 34 includes a motor 341 and two impellers 342 arranged back to back. A motor seat 3111 is provided on the first air inlet grille 311, and the motor 341 is installed in the motor seat 3111. A bearing seat 3121 is provided on the second air inlet grille 312, and a bearing 344 is nested in the bearing seat 3121. The output shaft of the motor 341 is connected to the bearing 344 after passing through the two impellers 342. Among them, both impellers 342 are centrifugal impellers 342. A partition 343 is provided between the two impellers 342, and the two impellers 342 are arranged axially offset. Refer to Figure 4 , the offset arrangement of the two impellers 342 means that the projections of each pair of relative blades of the two impellers 342 along the axis do not overlap.

[0037] The filter assembly 33 is annular and sleeved between the fan 34 and the water tank 321. The filter assembly 33 is a filter structure that can adsorb or decompose harmful gases in the air, such as a HEPA filter or an activated carbon filter mesh, etc. The HEPA filter usually includes three filter layers (primary filter layer, charged layer, electrostatic dust collection layer), and the removal efficiency of particles with a diameter of less than 0.3 microns can reach more than 99.97%.

[0038] Refer to Figure 2 , Figure 3 , Figure 5A And Figure 5B , the humidification component 32 includes a water tank 321 and an ultrasonic atomizer 322. The water tank 321 further includes two annular water storage boxes 3211 arranged axially, and an upper water box 3212 and a lower water box 3213 that respectively communicate with the upper and lower parts of the two water storage boxes 3211. An inlet 3214 is provided on the upper water box 3212, and a filling port 314 is opened at the corresponding position on the housing 31. The filling port 314 is communicated with the inlet 3214. Two ultrasonic atomizers 322 are provided on the lower water box 3213, and the two ultrasonic atomizers 322 are arranged on the hollow side between the two annular water storage boxes 3211. More preferably, the two water storage boxes 3211, the upper water box 3212, and the lower water box 3213 can be integrally formed.

[0039] The advantages of the above setting method are as follows: By arranging casters under the base 11 and a hydraulic lifting mechanism between the base 11 and the support part 13, the air purification humidifier of the present invention can be moved and adjusted in height up and down, thus meeting the humidification and purification requirements at different heights. The setting method of driving the double fan blades 342 by the fan 34 greatly increases the air intake volume and correspondingly reduces the noise at the same air intake volume. The partition 343 is arranged between the double fan blades 342 and the blades are arranged in a staggered manner, ensuring that the air supply between the double fan blades 342 does not interfere with each other, and effectively preventing the phenomenon of unbalanced rotation of the fan 34 caused by centrifugal force, further reducing the running jitter and noise. The filter assembly 33 selects a HEPA filter, greatly enhancing the purification effect. The water tank 321 is set in the form of a combination of two annular water storage boxes 3211, an upper water box 3212 and a lower water box 3213. The structure is novel and unique. Not only can the water tank 321 and the HEPA filter be nested outside the fan 34 at the same time, greatly reducing the volume of the air purification humidifier, but also the air output volume of the fan 34 and the water storage capacity of the water tank 321 are ensured. The upper water box 3212 is provided with a water outlet communicated with the water injection port on the housing 31, enabling the user to add water without removing the water tank 321, improving the convenience of use of the present invention. The selection of the ultrasonic atomizer 322 can not only humidify the air, but also combine with the smoke and dust floating in the air during the atomization process to make them precipitate, making the air fresher.

[0040] It should be noted that the above preferred implementation manners are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above setting method so that the present invention can be applied to more specific application scenarios.

[0041] For example, in an alternative implementation manner, the composition form of the water tank 321 and the form of the atomization device are not unique, as long as the setting method of the water tank 321 can meet the conditions of being sleeved between the housing 31 and the fan 34 and the atomization device can generate water mist. For example, the water tank 321 can also be a combination of multiple annular water storage boxes 3211, an upper water box 3212 and a lower water box 3213. The atomization device can also be an evaporation humidifier, an electrode humidifier, etc. The water tank 321 can also be set in a non-integrally formed manner, but in forms such as bonding and sealed connection.

[0042] Again, for example, in another alternative implementation manner, the setting position of the water inlet 3214 can be adjusted arbitrarily, as long as it is at a relatively high position of the water tank 321 to facilitate water addition.

[0043] For another example, in another alternative embodiment, the installation positions of the motor base 3111 and the bearing seat 3121 can be swapped, that is, the bearing seat 3121 is provided on the first air inlet grille 311, and the motor base 3111 is provided on the second air inlet grille 312. At this time, the fan 34 can be installed in the reverse direction.

[0044] For another example, in another alternative embodiment, the installation form of the fan 34 can also be adjusted, as long as the adjustment can meet the conditions of two-way air inlet and radial air outlet. For example, a partition 343 may not be provided between the two fan blades 342, and the two fan blades 342 may not be arranged with a displacement.

[0045] For another example, in another alternative embodiment, the rolling element 111 can be any other roller in addition to the universal wheel, and the lifting part 12 can be in other forms in addition to the hydraulic lifting mechanism, such as a lead screw mechanism, a rack and pinion mechanism, etc.

[0046] For another example, in another alternative embodiment, the support part 13 and the housing 31 can also be connected by snap connection, screw connection, welding or bonding, etc.

[0047] Of course, the above alternative embodiments can be used in cross combination with each other, and between the alternative embodiments and the preferred embodiments, so as to combine new embodiments to be applicable to more specific application scenarios. For example, on the basis of the preferred embodiment, while replacing the hydraulic lifting mechanism with a lead screw mechanism, the support part 13 and the housing 31 can be connected by screws, so as to combine a new embodiment.

[0048] Next, in conjunction with Figure 3 and Figure 6 a brief description will be given of the working principle of the air purification humidifier of the present invention. Among them, Figure 6 is a schematic diagram of the working principle of the air purification humidifier of the present invention.

[0049] As Figure 3 and Figure 6 shown, when the air purification humidifier is working, the motor 341 drives the two fan blades 342 arranged with a displacement to rotate at a high speed and smoothly. Indoor air is simultaneously inhaled into the housing 31 through the first air inlet grille 311 and the second air inlet grille 312, and is thrown out radially along the housing 31 under the drive of the fan blades 342. After the air is efficiently filtered by the HEPA filter, most of the particles in the air are removed, and the remaining clean air passes through the filter and is blown out from the circumferential air grille 313 together with the water mist generated by the ultrasonic atomizer 322, thereby humidifying and purifying the indoor air.

[0050] In summary, the advantages of the air purification humidifier of the present invention are as follows:

[0051] 1) It integrates the functions of purification and humidification, with novel structure, convenient use and strong spatial mobility. 2) It is convenient to add water to the water tank 321. Water can be added easily without disassembling the shell. The device can be placed at a low position through the hydraulic rod for water addition, eliminating the need to raise the arm for water addition and reducing labor intensity. 3) The air supply scheme is unique and novel. The double-inlet grille design ensures a large air intake and low noise. 4) The air purification humidifier can increase the indoor humidity, enabling the human body to be in a good physiological and mental state, with better effects in work and rest. Moreover, a healthy humidity can not only inhibit the breeding and spread of germs but also improve immunity. Secondly, the air humidifier also has the function of purifying the environment. During the atomization process, the ultrasonic atomizer 322 releases a large amount of negative oxygen ions, which can not only effectively increase the indoor humidity and moisten the dry air but also combine with the smoke and dust floating in the air to make them precipitate, thus effectively removing paint smell, mildew smell, smoke smell and odor, making the air fresher.

[0052] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
