The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the embodiments described below are some, but not all embodiments of the present invention.

Referring to fig. 1 to 5, an air purification apparatus 100 according to an embodiment of the present invention is described, which is suitable for a refrigeration device such as a refrigerator or a freezer, and may also be suitable for a storage device such as a locker, and the air purification apparatus 100 is described below with a specific example.

Referring to fig. 1, an air purification apparatus 100 according to an embodiment of the present invention includes a housing 110 and a plurality of adsorption members 120, where the housing 110 is substantially rectangular, an upper surface of the housing 110 is a first end surface, a plurality of guide holes 111 are disposed on the upper surface of the housing 110, the guide holes 111 are distributed on the upper surface at intervals, and the guide holes 111 extend toward a bottom of the housing 110, so that each guide hole 111 has a certain depth. Each guide hole 111 is inserted with a corresponding suction member 120, and the depth of the guide hole 111 can accommodate at least the height of the suction member 120, so that the suction member 120 can move in the height direction of the guide hole 111 in the guide hole 111.

As shown in fig. 1, in some embodiments, the guide hole 111 is a circular hole, the suction member 120 is substantially cylindrical, the diameter of the guide hole 111 is larger than the diameter of the suction member 120, and the suction member 120 can extend out of the housing 110 from the guide hole 111 and can also retract into the housing 110 along the guide hole 111 so as to be received in the housing 110. The guide holes 111 may be arranged in an array, and fig. 1 shows a state where all the adsorbing members 120 extend out of the housing 110, and in the extended state, the adsorbing members 120 are arranged in an array on the top of the housing 110, so that the adsorbing members 120 can contact with air to adsorb odor in the air, thereby achieving an odor purification effect.

It should be noted that the shapes of the guide hole 111 and the adsorbing member 120 are not limited to those shown in the embodiment in fig. 1, the guide hole 111 may be a square hole, an elliptical hole, a triangular hole, a strip-shaped hole, etc., and the shape of the adsorbing member 120 matches the shape of the guide hole 111, for example, when the guide hole 111 is a strip-shaped hole, the adsorbing member 120 may be set to be flat, and be plate-shaped as a whole, and may be inserted into the strip-shaped hole in a matching manner, so that the adsorbing member 120 can move along the guide hole 111, and details are not repeated. It can be understood that the number of the guide holes 111 is the same as the number of the absorption members 120, so that the guide holes 111 and the absorption members 120 can correspond to each other one by one, the number of the absorption members 120 can be set according to the actual application requirement, and the larger the number of the absorption members 120, the higher the odor purification efficiency and the better the effect.

It is understood that the absorbent member 120 may remove the odor from the air by physical absorption, for example, the absorbent member 120 may be made of activated carbon material, which can effectively remove the odor and bacteria. Certainly, the adsorbing member 120 may also be made of other materials with odor removing effect, and a catalyst or other materials may be coated on the surface of the adsorbing member 120, so that when air contacts with the catalyst material, the odor molecules can be decomposed quickly, thereby achieving the purpose of removing odor.

Taking the refrigerator as an example for explanation, the air purification apparatus 100 of the embodiment may be installed in the air duct of the refrigerator, or may be directly installed in the compartment of the refrigerator. When the refrigerator needs to remove odor, the adsorbing member 120 extends out of the casing 110 from the guide hole 111, so that the adsorbing member 120 is directly contacted with the air in the refrigerator, and the odor of the air can be adsorbed, thereby achieving the odor removing effect. When purification is finished or the smell is not needed to be removed, the adsorption piece 120 can be retracted into the shell 110 from the guide hole 111, the use is more flexible, the adsorption piece 120 can be stored in the shell 110 to reduce the contact with air, the consumption efficiency of the adsorption material is reduced, and the service life is prolonged.

Referring to fig. 1, a driving mechanism is provided at the bottom of the housing 110, and the driving mechanism generates a driving force to act on the bottom of the suction member 120, so that the suction member 120 can be driven to extend out of the housing 110 from the guide hole 111, or the suction member 120 can be driven to retract into the housing 110 from the guide hole 111, thereby achieving automatic telescopic movement of the suction member 120. It can be understood that, as shown in fig. 1, when the odor-removing treatment is required, the driving mechanism generates an upward driving force to push the absorbing member 120 to move upward and protrude out of the upper surface of the housing 110; when the smell is finished, the driving mechanism generates a downward driving force to retract the adsorbing member 120 into the housing 110.

It should be noted that, the driving mechanism may generate the driving force by electric or pneumatic means, and since there are a plurality of suction members 120, a part of the suction members 120 may be driven by the driving mechanism to extend out of the housing 110, and another part of the suction members 120 may remain stationary, that is, located in the housing 110, at this time, it may be understood as the first state of the suction members 120, and since there is a height difference between the suction members 120 in the extended state and the stationary state, a three-dimensional shape may be formed by different arrangement and combination means, for example, the suction member 120 in the middle of the housing 110 protrudes out of the upper surface, and the suction member 120 near the edge does not expose out of the upper surface; also can be convex adsorption part 120 and not convex adsorption part 120 arrange, can also form shapes such as characters or pattern, have visual molding, can bring more audio-visual use impression for the user, for display methods such as light or plane printing pattern, can change holistic outward appearance, have better visual effect, help promoting visual experience.

It can be understood that the initial state of the absorption element 120 can be set to extend out of the housing 110, that is, the absorption element 120 is kept in a smell purification processing state, when the appearance modeling needs to be molded, a part of the absorption element 120 can be driven by the driving mechanism to retract into the housing 110, and the other part of the absorption element 120 keeps protruding out of the housing 110, so that the shapes of three-dimensional characters or patterns can be formed, and details are not repeated. Of course, the driving mechanism can drive all the suction members 120 to protrude out of the housing 110, as shown in the state shown in fig. 1, all the suction members 120 are arranged to form a matrix, which can be understood as the second state of the suction members 120. It is also possible to drive all the suction members 120 to retract into the housing 110, and the odor purification process is not performed at this time, which can be interpreted as the third state of the suction members 120. It should be noted that the height difference between the movable suction member 120 and the stationary suction member 120 is formed to generate the corresponding three-dimensional pattern, and not limited to that a part of the suction member 120 needs to be retracted into the housing 110, but all the suction members 120 may extend out of the housing 110 and the three-dimensional pattern may be formed by adjusting the height difference therebetween.

It should be noted that, in some embodiments, the driving force may be generated manually, and the adsorbing member 120 is pushed to move manually, for example, a human hand may push the adsorbing member 120 directly from the bottom of the housing 110, so that part or all of the adsorbing member 120 protrudes from the upper surface of the housing 110, and the adsorbing members 120 at different positions may be pushed to be arranged and combined, so as to obtain corresponding characters, patterns, and the like. After the odor purification treatment is completed, the adsorption member 120 is pushed from the upper surface of the housing 110 to retract downwards into the housing 110, so that the adsorption member 120 is manually controlled and adjusted.

It can be understood that an operating element for pushing the adsorbing member 120 to move may also be disposed on the housing 110, for example, a push rod is added on the housing 110, and the push rod may be manually operated to push a single adsorbing member 120 to move for adjustment, or to push a plurality of adsorbing members 120 to move simultaneously, so that the operation is flexible and convenient, and the specific form of the operating element is not further limited.

Referring to fig. 2 and 3, in the embodiment that the adsorption member 120 is driven by magnetic force for adjustment, the driving mechanism includes a plurality of magnets 122 and a plurality of magnetic generation units 140, a magnet 122 is disposed at the bottom of each adsorption member 120, the magnet 122 is a permanent magnet, and the magnetic generation units 140 are fixedly disposed at the bottom of the housing 110. It can be understood that the bottom surface of the housing 110 is a second end surface, the magnetic generation units 140 are distributed and arranged on the second end surface, each magnetic generation unit 140 and the magnet 122 are arranged in a one-to-one correspondence, the magnetic poles of the magnets 122 facing the magnetic generation units 140 are fixed, the magnetic generation units 140 can generate magnetic fields by adopting an electric driving mode, and the driving mechanism can change the magnetic pole directions of the magnetic generation units 140 through the control unit.

When the magnetic poles of the magnetic generating unit 140 and the magnet 122 are opposite to each other, mutually repulsive magnetic forces are generated, so that the attraction member 120 is pushed by the magnetic forces to move towards the first end surface direction, i.e., the attraction member 120 protrudes from the upper surface of the housing 110. When the magnetic poles of the magnetic generating unit 140 and the magnet 122 are opposite in polarity, a magnetic force is generated to attract each other, so that the suction member 120 can be attracted to move toward the second end surface, and the suction member 120 can be retracted into the housing 110. It should be noted that the control unit may control a part of the magnetic generating units 140 and the corresponding magnets 122 to generate repulsive magnetic force, and control another part of the magnetic generating units 140 and the corresponding magnets 122 to generate attractive magnetic force, so as to achieve the purpose of controlling a part of the adsorbing member 120 to move outward.

Specifically, referring to fig. 1 and 2, a chassis 130 is disposed at the bottom of the housing 110, the magnetic generating units 140 are fixed to the chassis 130, the magnetic generating units 140 are not easily displaced, adjacent magnetic generating units 140 are spaced apart by a certain distance, the distribution positions of the magnetic generating units 140 and the positions of the guide holes 111 can be in one-to-one correspondence, the guide holes 111 can penetrate through the entire housing 110 in the height direction of the housing 110, and the chassis 130 can restrict the suction member 120 from being separated downward from the housing 110. In the embodiment, the combined structure of the magnetic generating unit 140 and the chassis 130 can also be referred to as a magnetic disc, and the magnetic disc is detachably connected to the housing 110 for easy installation and maintenance.

It can be understood that magnet 122 is fixed in the bottom of adsorbing piece 120, because adsorbing piece 120 receives the restriction of guiding hole 111, when magnet 122 received the magnetic force effect, magnet 122 can drive adsorbing piece 120 and reciprocate along guiding hole 111, realizes adsorbing piece 120's scalable regulation to can make adsorbing piece 120 arrange and form visual molding, bring audio-visual use feeling for the user, promote visual experience.

Referring to fig. 3, in some embodiments, the adsorbing member 120 includes a metal column 121, the metal column 121 is a cylinder, a magnet 122 is connected to a bottom end of the metal column 121, and the metal column 121 itself has an adsorbing property and can adsorb the odor gas. Specifically, the metal column 121 includes iron powder, iron oxide, carbon, and titanium dioxide, and the material may be made into particles, and the metal column 121 is composed of the particles, and the particles have gaps therebetween, which is beneficial to increase the contact between the metal column 121 and air.

In the embodiment, the mass ratio of the iron powder is 80%, the mass ratio of the iron oxide is 10%, the mass ratio of the carbon is 5%, and the mass ratio of the titanium dioxide is 5%, the iron oxide, the carbon and the titanium dioxide have a catalytic effect, the titanium dioxide component is doped in the metal column 121, so that the decomposition of pollutants in the air such as nitrogen oxides, aromatic hydrocarbons and aldehydes can be increased, and the effect of purifying and removing peculiar smell can be realized when the air is in contact with the metal column 121.

It should be noted that titanium dioxide is a photocatalyst material, and generates a substance having a strong oxidizing property (e.g., hydroxyl radical, oxygen gas, etc.) under light irradiation, and can be used to decompose organic compounds, partially inorganic compounds, bacteria, viruses, etc., and based on this, the adsorbing member 120 can be irradiated with light from the inside of a refrigerator, a locker, etc., thereby efficiently purifying air.

Considering that the larger the contact area of the metal column 121 with air, the stronger the catalytic action and the higher the odor removal efficiency, in the embodiment, the grooves are added on the surface of the metal column 121, and the contact area with air can be increased by the grooves. It will be appreciated that the greater the depth, width, etc. of the groove, the greater the contact area.

In some embodiments, the groove extends spirally along the length of the metal pillar 121, so that the surface of the metal pillar 121 forms a spiral groove; the grooves can also form annular grooves around the metal column 121, a plurality of annular grooves can be arranged and distributed at intervals along the length direction of the metal column 121, the depth, the width and other dimensions of the grooves can be set according to the actual structure of the metal column 121, and the grooves are not limited, so that the contact area between the metal column 121 and air can be increased through the grooves. In some embodiments, the grooves may be disposed to extend along a radial direction of the metal pillar 121, so that a hollow structure may be formed inside the metal pillar 121, and a contact area between the metal pillar 121 and air is further increased.

Referring to fig. 2 and 3, in the embodiment, the height of each metal column 121 is 10cm to 20cm and the diameter is 5mm to 10mm, it can be understood that, on the chassis 130, the magnetic generating unit 140 and the magnet 122, the size of the magnetic pole diameter of the magnetic generating unit 140 is close to the diameter of the projection area of the metal column 121 on the chassis 130, or the size of the magnetic pole diameter of the magnetic generating unit 140 is larger than the diameter of the projection area of the metal column 121, and the magnetic generating unit 140 can provide a stable magnetic action to the metal column 121.

It should be noted that, the chassis 130 of the embodiment is made of plastic, and the area range of the chassis 130 may be 20cm × 20cm — 30cm × 30cm, wherein the proportion of the area occupied by the magnetic generating units 140 on the chassis 130 reaches 80% -90%, it can be understood that the more the magnetic generating units 140 are arranged on the chassis 130, the more the corresponding adsorbing members 120 are, the more the arrangement of the adsorbing members 120 is compact, and the more intuitive shape can be easily pieced together. On the contrary, when the number of the suction members 120 is too small, the outlines of the characters or patterns formed by the arrangement are easily unclear, and it is difficult to highlight the shape desired by the user.

Referring to fig. 4, the magnetic generating unit 140 includes a metal tube 141 and a coil 142, the metal tube 141 is made of a metal iron tube, the coil 142 is spirally wound on the metal tube 141, and it can be understood from a magnetic effect of a current that the coil 142 generates a magnetic field when energized, fig. 4 is a schematic circuit diagram of the magnetic generating unit 140, in which the control unit includes a switch S for switching a current direction of the coil 142, and P is a rheostat. It can be understood from the ampere rule that the magnetic poles at the two ends of the metal tube 141 are changed by changing the current direction of the coil 142 through the switch S.

To illustrate by a specific example, a magnetic pole of one end of the magnet 122 facing the magnetic generating unit 140 is an N pole, as shown in fig. 4, when the end a and the end B of the switch S are switched on, a current enters from one end of the coil 142 near the end a and flows out from one end near the end B, at this time, the magnetic pole of the end a of the metal tube 141 is an N pole, and the opposite magnetic poles of the metal tube 141 and the magnet 122 are the same in polarity, so that the magnetic generating unit 140 and the magnet 122 generate a mutually repulsive magnetic force to push the adsorbing member 120 to extend out of the housing 110. When the switch S is switched to the end a and the end c to be conducted, the current on the coil 142 flows in the opposite direction, the magnetic pole at the end a of the metal tube 141 is the S pole, and the opposite magnetic poles of the metal tube 141 and the magnet 122 are opposite, so that the magnetic generating unit 140 and the magnet 122 generate a mutually attracted magnetic force to pull the adsorbing member 120 to return to the housing 110, thereby realizing the change of the magnetic field direction by electric control adjustment.

It should be noted that each magnetic generation unit 140 is correspondingly connected with a switch, that is, each magnetic generation unit 140 can be independently controlled, so that the movement direction of the corresponding adsorption member 120 can be independently adjusted, the combination of the adsorption member 120 is more flexible, and the working principle of each magnetic generation unit 140 and the switch can refer to the schematic diagram shown in fig. 4, which is not described again in detail.

Referring to fig. 5, fig. 5 is a top view of the air purification apparatus 100 according to an embodiment, where the shaded guide holes 111 indicate that the absorption member 120 protrudes from the upper surface, and the positions of the other guide holes 111 indicate that the absorption member 120 does not expose out of the housing 110, at this time, the protruding absorption members 120 are arranged to form a character shape of "china", so that the air purification apparatus 100 can perform odor purification treatment, and can also display a unique appearance and shape, thereby providing a more intuitive use feeling and a better visual experience for a user.

In some embodiments, the driving mechanism drives the adsorbing member 120 to move in an electric manner, specifically, the driving mechanism includes a motor and a transmission assembly, the transmission assembly may be a structure that a gear is combined with a push rod, a screw rod, and the like, for example, the push rod is connected to the adsorbing member 120, and the motor drives the adsorbing member 120 to move by being driven by the gear, so as to drive the adsorbing member 120 to extend and retract. It should be noted that the transmission assembly may synchronously link a plurality of adsorbing members 120 to move together, or each adsorbing member 120 may be driven by an independent transmission assembly, so that the combination of the adsorbing members 120 is more flexible.

Referring to fig. 6 to 10, a purification control method according to an embodiment of the present invention is described, the purification control method is applied to the air purification apparatus 100 shown in the above embodiment, and the specific structure of the air purification apparatus 100 may refer to the embodiment shown in fig. 1 to 5, which is not described herein again, and the purification control method is described with specific examples below.

Referring to FIG. 8, in some embodiments, the purge control method is not limited to the following steps:

step S140, responding to the operation of the user on the electronic equipment, acquiring display elements and generating control signals, wherein the display elements comprise preset patterns or online edited patterns;

and S150, controlling the driving mechanism to operate according to the control signal.

When the user changes the pattern or cancels the pattern, the user presses "cancel interesting net smell display", at this time, the control unit changes the magnetic pole direction of the magnetism generating unit 140 at the position corresponding to the pattern, so that the corresponding adsorption piece 120 is reset, and the air purification device 100 is restored to the initial state of not displaying the pattern.

Referring to FIG. 10, in some embodiments, a purge control method includes, but is not limited to, the following steps:

step S160, when the concentration of the odor gas detected by the concentration sensor is higher than a preset threshold value, generating a control signal;

and step S170, controlling the driving mechanism to operate according to the control signal.

It can be understood that, taking the refrigerator as an example, food stored in the refrigerator for a long time can easily deteriorate to produce bacteria breeding, and the gas produced by bacteria metabolism, such as hydrogen sulfide methylamine and the like, can be provided with a gas sensor for detecting the concentration of the odor gas inside the refrigerator, and the air quality condition of the internal space of the refrigerator can be obtained in real time through the gas concentration sensor, and when the concentration of the odor gas is higher than a preset threshold value, a control signal can be generated and sent to the air purification device 100, so that the driving part or all of the adsorption pieces 120 extend out of the shell 110 to perform air purification, and the active adjustment of the movement of the adsorption pieces 120 is realized, and the effect of rapid odor purification is achieved. In some preferred embodiments, the number of the adsorption members 120 extending out of the housing 110 can be adjusted according to the concentration of the odor gas, and the higher the concentration is, the greater the number of the adsorption members 120 controlled to move.
