The utility model provides an air purification device, air purification device can be applied to the machine in the air conditioning, especially the machine in the console mode air conditioning. The air purification device is used for purifying air and sending the purified air to the indoor environment, so that the air quality of the indoor environment is improved.

Referring to fig. 1 and 2, in an embodiment of the air purification apparatus 100 of the present invention, the air purification apparatus 100 includes a housing 110 and a purification module 130. The housing 110 has an air inlet 111 and an air outlet 112, a purification chamber 121 communicating the air inlet 111 and the air outlet 112 is disposed inside the housing 110, and a mounting opening 114 corresponding to the purification chamber 121 is further disposed on an outer surface of the housing 110. The purge module 130 is mounted in the purge chamber 121, and the purge module 130 has an operating position (shown in fig. 3 and 4) in which it is located in the purge chamber 121 and a maintenance position (shown in fig. 8 and 9) in which it is resiliently returned to the outside of the mounting port 114 after receiving an inward pressing force and is drawn out of the mounting port 114.

Referring to fig. 3 to 5, specifically, the housing 110 is substantially cylindrical and extends in the vertical direction, for example, the housing 110 may be square or circular. The purge air duct 113 in the housing 110 also extends in the vertical direction. The inside of the housing 110 is also formed with a purge air duct 113 below the purge chamber 121. An air inlet 111 is formed at the bottom of the housing 110 or on a side wall near the bottom, and the air inlet 111 is communicated with the lower end of the purification air duct 113. An air outlet 112 is formed at the top of the casing 110 or on the side wall near the top, and the air outlet 112 is communicated with the upper end of the purifying air duct 113 through the purifying cavity 121.

A mounting bracket 120 is further disposed in the housing 110, and the mounting bracket 120 forms a purification chamber 121. The purification module 130 is installed in the purification chamber 121 to be drawable in the inner and outer directions, and the purification module 130 can be drawn out of the purification chamber 121 or moved into the purification chamber 121 through the installation opening 114. As noted above, the purification module 130 has an operating position and a maintenance position. When the air purification device 100 purifies air, the purification device is in the working position, the purification module 130 corresponds to the cross section of the purification air duct 113, and the air enters the purification air duct 113 from the air inlet 111 and flows from bottom to top in the purification air duct 113; when the air passes through the purifying chamber 121, the air is purified by the purifying module 130 to remove impurities such as dust, bacteria, microorganisms or organic matters in the air, so as to obtain relatively clean air. Finally, this portion of clean air is blown out of the outlet 112.

When the air purification apparatus 100 needs to be maintained, an outward pressing force is applied to the purification module 130, and the purification module 130 moves into the purification chamber 121 by a first preset distance under the action of the pressing force, and then rebounds outward by a second preset distance to enable the purification module 130 to reach the maintenance position. Obviously, the second predetermined distance is greater than the first predetermined distance, so the purification module 130 located at the maintenance position extends outward from the installation opening 114, and thus the purification module 130 is easier to be pulled by a user, and the user can conveniently pull the purification module 130 out from the maintenance position, thereby greatly reducing the difficulty of pulling.

The technical scheme of the utility model, through installing purification module 130 in purifying chamber 121, purification module 130 has the operating position who is located purification chamber 121 to and the maintenance position that can be taken out by installing port 114 after receiving inward pressing force kick-backs to the installing port 114 outside, thereby through applying a pressing force to purification module 130, can make purification module 130 kick-back from the operating position maintain the position, can be taken out purification module 130 from this maintenance position (can refer to aforementioned explanation in detail) by the user, can need not to set up handle structure on purification module 130, reduce user's pull and purify the dynamics of module 130, greatly reduced the degree of difficulty of dismouting purification module 130, improve the assembly efficiency of dismouting purification module 130.

Referring to fig. 3 to 5, in an embodiment, the cleaning module 130 has a pressing surface 131 for applying the pressing force. When the purification module 130 is in the working position, the pressing surface 131 of the purification module 130 may be completely located inside the mounting opening 114, may be flush with the mounting opening 114, or may slightly protrude from the mounting opening 114. In order to reduce the difficulty of extracting the purification module 130, the distance from the pressing surface 131 to the installation opening 114 when the purification module 130 is in the maintenance position may be set to be greater than the distance from the pressing surface 131 to the installation opening 114 when the purification module 130 is in the working position.

For convenience of explanation, it is assumed herein that the distance D from the pressing surface 131 to the mounting opening 114 when the purification module 130 is in the operating position₁And the distance D from the pressing surface 131 to the mounting opening 114 when the purification module 130 is in the maintenance position₂. Then there should be: d is not less than 0cm₁≤D₂. This ensures that the purification module 130, in the maintenance position, extends a longer distance from the mounting port 114, thereby making it easier for the user to pull out the purification module 130 by hand.

It is also taken into account here if D₂If the size is too small, the position of the user holding the purification module 130 is small, which is inconvenient for holding the purification module 130; if D is₂Too large, a resilient structure with large resilience needs to be added inside the purification chamber 121, which increases the complexity of the resilient structure. The research experiment shows that when the distance from the pressing surface 131 to the mounting opening 114 is 1 cm-5 cm when the purification module 130 is located at the maintenance position, the purification module 130 located at the maintenance position can be held by a user, the holding position is sufficient, the required resilience force is small, and therefore the resilience structure does not need to be complex. Therefore, the distance from the pressing surface 131 to the mounting opening 114 when the purification module 130 is in the maintenance position is optionally 1cm to 5 cm. That is, 1cm ≦ D₂≤5cm。D₂Specific examples include, but are not limited to: 1cm, 2cm, 3cm, 4cm, 5cm, etc.

Referring to fig. 3 to 5, based on any of the above embodiments, the manner of returning the cleaning module 130 to the maintenance position after receiving the inward pressing force to the outside of the mounting opening 114 is implemented in various ways, and is not limited in particular. In one embodiment, the air purification apparatus 100 further comprises a latch assembly including a push-type latch 200 and a top post 300 adapted to the push-type latch 200, wherein one of the push-type latch 200 and the top post 300 is mounted on an outer surface of the purification module 130, and the other is mounted on an inner wall of the purification chamber 121. The mating structure of the press-lock latch 200 and the top post 300 is common.

The operation principle of the push-button type lock 200 installed on the inner wall of the purification chamber 121 and the top pillar 300 installed on the purification module 130 is as follows:

referring to fig. 3 to 5, when the purification module 130 is installed in the purification cavity 121, the top pillar 300 of the purification module 130 is pushed into the press type lock catch 200 in the purification cavity 121 and is connected to the press type lock catch 200; at this time, the push-type lock 200 and the top pillar 300 are in a locked state (as shown in fig. 5), the purification module 130 is fixed in the purification chamber 121, and the purification module 130 cannot be drawn out of the installation opening 114.

Referring to fig. 6 to 8, after a pressing force is applied to the pressing surface 131 of the purification module 130, the pressing type latch 200 is triggered to release the top post 300, and the purification module 130 is pushed by the top post 300 to move towards the outside of the installation opening 114, so that the top post 300 is separated from the pressing type latch 200; at this time, the push type lock 200 and the top post 300 are in the unlocked state (as shown in fig. 9 and 10), and the purification module 130 is restored to be free, so that the purification module 130 can be withdrawn by the user from the mounting opening 114 to the outside.

Of course, in other embodiments, the latch assembly is not required. The cleaning module 130 rebounds to the maintenance position to the outside of the mounting opening 114 after receiving the inward pressing force, and an elastic structure may be disposed on the first inner wall 1211 of the cleaning chamber 121, and the elastic structure is in an initial state (no elastic potential energy is accumulated) when the cleaning module 130 is in the working position. When an inward pressing force is applied to the purge module 130, the purge module 130 presses the elastic structure, so that elastic potential energy is accumulated in the elastic structure. At this time, the pressing force is removed, and the elastic structure releases the elastic potential energy to push the purification module 130 to rebound outwards. It can be seen that the elastic structure can accumulate sufficient elastic potential energy, so that the cleaning module 130 can be rebounded to the maintenance position to the outside of the mounting port 114 after receiving the inward pressing force.

Referring to fig. 12 to 14, in the present embodiment, the cleaning module 130 rebounds to the maintenance position to the outside of the mounting opening 114 after receiving an inward pressing force in such a manner that the latch assembly is adopted. For the structure of the push-type lock 200, the push-type lock 200 includes:

a housing 210, the housing 210 having a cavity 211 and an opening 212 formed at one end of the cavity 211;

the sliding block 220 is movably arranged in the accommodating cavity 211 along the inner direction and the outer direction, and a top pressing surface 221 for supporting the top pillar 300 is formed at the outer end of the sliding block 220; a heart-shaped groove 222 is formed in the side surface of the slider 220 (the heart-shaped groove 222 can refer to fig. 20 and 24), and the heart-shaped groove 222 comprises a V-shaped groove 201, and a forward-stroke groove 202 and a backward-stroke groove 203 which are positioned on two sides of the V-shaped groove 201; wherein, two ends of the V-shaped groove 201 are respectively connected with the outer end of the return groove 203 and the outer end of the return groove 203, and the concave part of the V-shaped groove 201 forms a first hook position 204; the inner end of the going slot 202 is connected with the inner end of the returning slot 203, and a second hook position 205 is formed at the connection part;

the two clasping blocks 230 are arranged at the outer ends of the sliding blocks 220 in a relatively rotatable manner;

the two ends of the elastic member 240 are respectively connected with the bottom wall of the cavity 211 and the inner end of the sliding block 220;

one end of the locking rod 250 is fixedly connected with the bottom wall of the accommodating cavity 211, the other end of the locking rod 250 forms a hook 251 in sliding fit with the heart-shaped groove 222, and the hook 251 can be switched between the first hook position 204 and the second hook position 205 of the heart-shaped groove 222.

As shown in fig. 17 to 20, in particular, the two clasping blocks 230 can be rotatably connected with the sliding block 220, so that the two clasping blocks 230 can rotate relatively; or the two clasping blocks 230 can be flexibly connected with the sliding block 220, or the two clasping blocks 230 can rotate relatively. The two hugging blocks 230 can be rotated toward each other to close or rotated away from each other to open. For the heart-shaped groove 222 on the sliding block 220, one end of the V-shaped groove 201 of the heart-shaped groove 222 is in arc transition connection with the outer end of the forward-stroke groove 202, and the other end of the V-shaped groove 201 is also in arc transition connection with the outer end of the backward-stroke groove 203. The bottom wall of the housing 210 is further provided with a fixing post 260 in a protruding manner, and the elastic member 240 is sleeved on the fixing post 260. The elastic member 240 may be a spring plate or a spring, and is selected to be a spring. In order to prevent the sliding block 220 from completely falling out of the cavity 211, the side wall of the housing 210 is opened in a limiting sliding groove 213 arranged along the moving direction of the sliding block 220, and a limiting protrusion 223 is further convexly arranged on the other side surface of the sliding block 220, and the limiting protrusion 223 is limitedly installed in the limiting sliding groove 213 and slides along the limiting sliding groove 213.

Referring to fig. 12, in the initial state (i.e., the unlocked state), the hook 251 of the locking lever 250 of the push type lock 200 is hooked at the second hook position 205, and the two clasping blocks 230 are exposed from the opening 212 of the housing 210 and are opened back to back. Referring to fig. 18 to 20, when the purification module 130 is installed, the purification module 130 moves inward into the cavity 211 from the installation opening 114 until the top pillar 300 of the purification module 130 abuts against the top pressing surface 221 of the press-type lock latch 200; the purifying module 130 is continuously pressed, the top pillar 300 pushes the sliding block 220 to move inwards, the two clasping blocks 230 on the sliding block 220 move into the accommodating cavity 211 of the housing 210 from the opening 212, and the two clasping blocks 230 rotate in the direction approaching to each other to clasp the top pillar 300 under the guiding action of the two side walls of the opening 212. Meanwhile, the slider 220 compresses the elastic member 240 so that the elastic member 240 accumulates elastic potential energy; the hook 251 of the locking lever 250 moves outward relative to the slider 220 and moves outward from the first hook position 204 of the heart-shaped groove 222 along the going groove 202; when the hook 251 of the locking lever 250 reaches the outer end of the trip groove 202, the hook 251 abuts against the outer end of the trip groove 202, and the slider 220 cannot move inward any more. At this time, the pressing force is released, and the elastic member 240 releases a little elastic potential energy to force the hook 251 to deflect from the outer end of the forward moving groove 202 into the V-shaped groove 201 under the action of the eccentric groove wall at the connecting position of the outer end of the forward moving groove 202 and the V-shaped groove 201. After the hook 251 reaches the first hook position 204 of the V-shaped groove 201, the hook 251 and the first hook position 204 are locked, that is, the locking rod 250 locks the slider 220 to limit its movement, and the two clasping blocks 230 completely "hug" the top pillar 300 in the cavity 211, so that the press-type lock 200 and the top pillar 300 are in a locked state, and the purification module 130 is fixed in the cavity 211.

Referring to fig. 21 to 24, when the purification module 130 needs to be withdrawn, an inward pressing force is applied to the pressing surface 131 of the purification module 130, so that the hook 251 of the locking rod 250 is separated from the first hook position 204 of the V-shaped groove 201 and moves to the return groove 203, the locking rod 250 releases the slider 220, and the slider 220 slides inward for a first preset distance relative to the locking rod 250; when the hook 251 of the locking lever 250 reaches the outer end of the return groove 203, the hook 251 abuts against the outer end of the return groove 203, and the slider 220 cannot move inward any more. At this time, when the pressing force is removed, the elastic member 240 releases the elastic potential energy to push the slider 220 to move outward, the slider 220 drives the two clasping blocks 230 to extend outward from the opening 212 of the housing 210, the limiting effect of the opening 212 on the two clasping blocks 230 is removed, the two clasping blocks 230 rotate in opposite directions to release the top pillar 300, and the top pillar 300 is pushed by the slider 220 to pop outward by a second preset distance. Meanwhile, under the action of the eccentric groove wall of the connecting position between the outer end of the return groove 203 and the V-shaped groove 201, the hook 251 of the locking rod 250 returns to the second hook position 205 along the return groove 203, and at this time, the two clasping blocks 230 of the press-type lock catch 200 completely release the top pillar 300, so that the press-type lock catch 200 and the top pillar 300 are in an unlocked state, and the user can conveniently draw out the purification module 130.

Referring to fig. 9 and 10, in one embodiment, the top pillar 300 of the purification module 130 is conveniently abutted with the press-type lock catch 200 inside the purification chamber 121, optionally, the inner wall of the purification chamber 121 includes a first inner wall 1211 opposite to the mounting opening 114, and the purification module 130 has a back surface 132 opposite to the first inner wall 1211; the push-type fastener 200 is disposed on the first inner wall 1211, and the top pillar 300 is mounted on the back 132 of the purification module 130. Therefore, the force application direction of the pressing force is consistent with the butting direction of the top column 300 and the push type lock catch 200, so that the top column 300 can be accurately pushed into the push type lock catch 200.

Specifically, the back 131 of the purification module 130 is provided with a sink groove 133, and the top pillar 300 is disposed on the bottom surface of the sink groove 133 and protrudes toward the opening of the sink groove 133. This allows the top post 300 not to protrude beyond the back 131 of the purification module 130 to reduce the space between the purification module 130 and the first inner wall of the purification chamber when the purification module 130 is in the operating position, reducing the footprint.

Further, to reduce the number of latch assemblies used, only one latch assembly may be employed. The push-type latch 200 of the latch assembly is installed in the middle of the first inner wall 1211, and the top pillar 300 of the latch assembly is installed in the middle of the back 132 of the purification module 130 and corresponds to the push-type latch 200.

Specifically, the inner wall of the purification chamber 121 further includes a second inner wall 1212 and a third inner wall 1213 located at both sides of the first inner wall 1211, the distance between the push button 200 and the second inner wall 1212 is the same as the distance between the push button 200 and the third inner wall 1213, and the top pillar 300 is disposed corresponding to the push button 200. Therefore, in the process of butting the push type lock catch 200 and the top pillar 300, the two side parts of the purification module 130 are stressed in a balanced manner and are not easy to turn over, so that the stability of fixing the purification module 130 is better.

Referring to fig. 6 and 9, the movable installation manner of the purification module 130 in the purification chamber 121 may be rolling or sliding. In one embodiment, the inner wall of the cleaning chamber 121 is provided with a guide chute 1214 extending in the inner and outer directions, and the guide chute 1214 is used for slidably mounting the cleaning module 130. Specifically, the second inner wall 1212 and the third inner wall 1213 are each provided with a guide chute 1214 that moves in the inward and outward directions, and the two guide chutes 1214 are slidably engaged with both sides of the purification module 130.

Referring to fig. 6 and 7, in an embodiment, the types of the purification modules 130 may be any one or more combinations of HEPA net modules, IFD modules, formaldehyde removing modules, electrostatic modules, water blocking modules, and anion modules. When purifying module 130 and being the IFD module, the last electronic component of IFD module needs to be connected with the power, if adopt the wire to connect, then at the in-process of pull purification module 130, easily pulls the wire, and then damages the IFD module.

With continued reference to fig. 6 and 7, to avoid this, when the purification module 130 is an IFD module, the back 132 of the purification module 130 is provided with first conductive contacts 170; the first inner wall 1211 of the purification chamber 121 is provided with a second conductive contact 180 for connecting to a power source, and the second conductive contact 180 corresponds to the first conductive contact 170 for abutting against the first conductive contact 170. During the process of pushing the purification module 130 into the purification chamber 121, the first conductive contacts 170 on the purification module 130 gradually approach the second conductive contacts 180; when the purification module 130 reaches the operational position, the first and second

conductive contacts

170 and 180 abut, thereby connecting the purification module 130 to a power source. When the purification module 130 is ejected from the purification cavity 121, the first conductive contact 170 and the second conductive contact 180 are separated, so that the purification module 130 can be taken out smoothly without the problem of wire pulling.

Referring to fig. 9 and 11, in one embodiment, it is considered that there may be a contact failure when the first conductive contact 170 and the second conductive contact 180 are not in tight contact. To solve this problem, the second conductive contact piece 180 may optionally include a connecting portion 171 protruding from the first inner wall 1211 toward the mounting opening 114, and an abutting portion 172 extending laterally from a protruding end of the connecting portion 171 for abutting against the first conductive contact piece 170; the first inner wall 1211 is provided with a support protrusion 190 protruding toward the abutting portion 172.

When the first conductive contact 170 on the purification module 130 is pressed against the second conductive contact 180, the second conductive contact 180 is pressed against the supporting protrusion 190, which is equivalent to the supporting protrusion 190 and the first conductive contact 170 are matched to clamp and fix the second conductive contact 180, thereby ensuring that the first conductive contact 170 and the second conductive contact 180 are in close contact, keeping good contact and avoiding the occurrence of poor contact.

Further, a raised portion 173 may be formed by raising the middle portion of the abutment portion 172 toward the mounting opening 114. When the first conductive contact 170 is pressed against the second conductive contact 180, the bump 173 of the second conductive contact 180 is elastically deformed, and the elastic potential energy accumulated in the bump 173 makes the first conductive contact 170 and the second conductive contact 180 contact more closely.

Referring to fig. 8, based on any of the above embodiments, the air purification module 130 further includes a fan assembly 140, and the fan assembly 1400 is installed on the top of the housing 110 and is used for driving air to enter from the air inlet 111 and to be blown out through the purification air duct 113 and the air outlet 112. The air cleaning device 100 further includes a rotating body 150; the housing 110 is further provided with a purification air duct 113 under the purification chamber 121, and the rotating body 150 is rotatably installed in the purification air duct 113, and the rotating body 150 can spin the water supplied to the rotating body 150 in a radial direction thereof by rotation.

The air cleaning module 130 further includes a water spray 160, the water spray 160 being in communication with a water source, the water spray 160 being configured to supply water to the rotating body 150. When the air purifying device 100 purifies air, the rotating body 150 is driven to rotate at a high speed, the rotating body 150 throws out water supplied by the water spraying member 160 to the rotating body 150 along the radial direction of the rotating body, a plurality of water particles are formed, the water particles have small particle size, and the water particles can fully contact with the air to melt and carry away impurities in the air, so that the supergravity water washing air purification is realized. The rotation axis of the rotating body 150 is vertically arranged, so that water thrown by the rotating body 150 vertically collides with air flowing from bottom to top in the purifying air duct 113, and is fully contacted with the air, thereby greatly improving the efficiency of purifying the air.

It is considered that, if the linear velocity of the outer edge of the rotating body 150 is too small during the rotation of the rotating body 150, the velocity of the water thrown out by the rotating body 150 is small, and the air purification effect is poor; on the other hand, if the linear velocity of the outer edge of the rotating body 150 is too high, the energy consumption of the rotation of the rotating body 150 is high and the noise is generated, and if the linear velocity of the outer edge of the rotating body 150 is continuously increased, the improvement of the air purification effect is small.

Therefore, in the present embodiment, when the air cleaning module 130 is required to operate, the linear velocity of the outer edge of the rotating body 150 is 10m/s to 45 m/s. Such as but not limited to: 10m/s, 15m/s, 18m/s, 20m/s, 25m/s, 30m/s, 35m/s, 38 m/s. The linear velocity of the outer edge of the rotating body 150 is limited to 10m/s to 45m/s, so that the velocity of the water thrown out by the rotating body 150 is ensured to be high, and the noise generated by the rotation of the rotating body 150 is small.
