The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 and 2, the air humidification/purification device 100 according to the preferred embodiment of the present invention has a dual function of humidifying and purifying air, so as to purify indoor air while increasing the water content of indoor air, thereby enabling a user to be in a fresh and humid environment.
The air humidification purifier 100 includes a body 10, a filter element 30, an air blower 50, and a humidification assembly 70. The filter element 30 and the air supply device 50 are both arranged in the machine body 10, and air entering the machine body 10 is filtered and purified by the filter element 30 and then is sent out by the air supply device 50. The humidifying assembly 70 is disposed on the machine body 10, and is used for atomizing water contained therein, and the atomized water can be carried into the environment by the air sent by the air supply device 50 to humidify the indoor air.
The machine body 10 comprises a lifting structure 11 and a shell 13 arranged on the lifting structure 11. The lifting structure 11 is generally disc-shaped and is positioned at the bottom of the body 10 to provide a mounting base for the filter element 30. The housing 13 has a substantially hollow cylindrical shape, and a purification chamber for accommodating the filter element 30 is formed therein. Meanwhile, a plurality of air passing holes 130 are formed around the corresponding positions of the shell 13 and the purifying chamber in a penetrating manner, and the filter core 30 is firmly arranged on the lifting structure 11 and is accommodated in the purifying chamber so as to filter and purify air entering from the plurality of air passing holes 130. Wherein, the filter core 30 adopts a novel carbon cloth composite filter screen, the purifying effect is improved and the volume is reduced.
In this embodiment, the body 10 is generally cylindrical, and the filter element 30 is cylindrical; it will be appreciated that in other embodiments, the shape of the body 10 and the shape of the filter element 30 may be varied as desired, for example, the body 10 and the filter element 30 may each be square cylinders, etc., without limitation.
Referring to fig. 3 and 4, the lifting structure 11 is further configured to provide a driving force for lifting the filter element 30 between a sealing position where the filter element is sealed with the top wall of the purifying chamber and a separating position where the filter element is spaced from the top wall of the purifying chamber so as to facilitate quick assembly and disassembly of the filter element 30. Specifically, the lifting structure 11 includes a base 110, a turntable 112 rotatably mounted on the base 110 in a circumferential direction, and a tray 114 mounted on the turntable 112 in a lifting manner for driving the filter element 30 to move up and down.
The base 110 has a substantially disk shape, and is used for supporting and positioning the turntable 112 and the tray 114, and guiding the rotation of the turntable 112. Wherein, the surface of the base 110 facing the turntable 112 is concavely formed with a receiving groove 1101 for receiving the turntable 112, so as to play a guiding and limiting role when the turntable 112 rotates circumferentially relative to the base 110 under the action of an external force.
The turntable 112 comprises a turntable body 1121, a toggle switch 1123 protruding from the outer edge of the turntable body 1121, and a plurality of lifting drive bosses 1125. The outer contour of the disc 1121 is matched with the formation of the accommodating groove 1101 and is at least partially accommodated in the accommodating groove 1101, so that the accommodating groove 1101 allows the disc 1121 to be accommodated in the accommodating groove in a circumferential rotatable manner, and simultaneously, the guiding and limiting effects on the rotation movement of the disc 1121 can be achieved. The toggle switch 1123 includes a connecting plate 11231 connecting the outer edge of the disc body 1121 and a toggle bump 11232. The connecting plate 11231 protrudes out of the tray 1121 and is rotatably supported on the base 110, and the stirring protruding point 11232 is convexly arranged on the surface of the connecting plate 11231 for being stirred by a user. The lifting driving bosses 1125 are circumferentially spaced apart from the surface of the tray body 1121 facing the tray 114, and each lifting driving boss 1125 extends longitudinally in a circumferential direction to form an arc shape.
Each lift drive boss 1125 includes a first inclined guide end 11250 and a first flat support end 11252 coupled to the first inclined guide end 11250. The height of the first inclined guiding end 11250 relative to the tray body 1121 is smaller than that of the first flat supporting end 11252, and the first inclined guiding end 11250 extends and transits towards the side of the first flat supporting end 11252 along the surface of the tray body 1121 in a manner that the protruding height gradually increases, so that each lifting driving boss 1125 is approximately in a trapezoid protruding and arranged on the surface of the tray body 1121. The first flat supporting end 11252 is disposed at the maximum protruding height end of the first inclined guiding end 11250, and the protruding height extends in a flat manner with the maximum protruding height of the first inclined guiding end 11250 unchanged.
The surface of the tray 114 facing the turntable 112 is convexly formed with a number of elevation fit bosses 1141 equal to the number of elevation drive bosses 1125. The lifting and engaging bosses 1141 are circumferentially spaced apart from the surface of the tray 114 facing the turntable 112, and each lifting and engaging boss 1141 extends longitudinally in a circumferential direction to form an arc shape.
Each lift-engaging boss 1141 includes a second angled pilot end 11410 and a second flat support end 11412 coupled to the second angled pilot end 11410. The height of the second inclined guiding end 11410 relative to the tray 114 is smaller than that of the second flat supporting end 11412, and the second inclined guiding end 11410 extends and transits towards the side of the second flat supporting end 11412 along the surface of the tray 114 in a manner that the protruding height gradually increases, so that each lifting matching boss 1141 is approximately trapezoid protruding and arranged on the surface of the tray 114. The second straight supporting end 11412 is disposed at the maximum protruding height of the second inclined guiding end 11410, and the protruding height extends straight from the maximum protruding height of the second inclined guiding end 11410.
Specifically, the first inclined guide end 11250 has a first inclined surface facing the tray 114 in the axial direction of the turntable 112, and the first flat support end 11252 has a first positioning surface facing the tray 114 in the axial direction of the turntable 112. The second inclined guide end 11410 has a second inclined surface facing the turntable 112 in the axial direction of the tray 114, and the second straight support end 11412 has a second positioning surface facing the turntable 112 in the axial direction of the tray 114. The first inclined surface and the second inclined surface are parallel and opposite in inclination direction, and the first positioning surface and the second positioning surface are planes parallel to each other.
When the dial switch 1123 on the turntable 112 is slid, the turntable 112 rotates along the staggered position of each lifting driving boss 1125 and each lifting matching boss 1141 (i.e. the separation position of the filter core 30) to the position where the lifting driving boss 1125 and the lifting matching boss 1141 are in up-down abutting fit (i.e. the sealing position of the filter core 30), the first inclined surface rotates to contact and fit with the second inclined surface, so as to guide the rotation of the turntable 112; when the lifting driving boss 1125 is rotated to vertically abut against and match with the lifting matching boss 1141, the filter core 30 just abuts against the top wall of the purification chamber and generates a vertical downward force on the lifting structure 11, so that the first positioning surface is in close contact with the second positioning surface, and the rotation of the turntable 112 is limited by the friction force between the first positioning surface and the second positioning surface (i.e. the rotation is performed to the position where each lifting driving boss 1125 is staggered from each lifting matching boss 1141), so as to achieve the self-locking effect.
Wherein, a circumferential distance (i.e., a minimum distance between two adjacent lift-fit bosses 1141 in a circumferential direction) is provided between each two adjacent lift-fit bosses 1141, and the circumferential distance between each two adjacent lift-fit bosses 1141 is greater than or equal to the circumferential extension length of each lift-drive boss 1125. In this way, each lifting driving boss 1125 is ensured to be respectively inserted in the circumferential space between each two adjacent lifting matching bosses 1141 when the turntable 112 is rotated, so that the turntable 112 can be rotated to the position where each lifting driving boss 1125 and each lifting matching boss 1141 are completely staggered with each other, and the height range of the lifting movement of the tray 114 driven by the turntable 112 is maximized, that is, the height range of the lifting movement can include the whole range of the first flat supporting end 11252 and the first inclined guiding end 11250.
In this embodiment, the number of the lifting driving bosses 1125 and the lifting matching bosses 1141 is three, the three lifting driving bosses 1125 are uniformly disposed on the tray body 1121, and the inclination directions of the first inclined guiding ends 11250 in the three lifting driving bosses 1125 are the same, so as to balance the trays 114 disposed on the turntable 112. The three lift-fit bosses 1141 are uniformly disposed on the tray 114, and the inclination directions of the second inclined guiding ends 11410 of the three lift-fit bosses 1141 are the same, and the inclination direction of each lift-fit boss 1141 is opposite to the inclination direction of the corresponding first inclined guiding end 11250. It will be appreciated that in other embodiments, the shape, number and placement of the lift drive tabs 1125 and the lift engagement tabs 1141 may be varied as desired and are not limited thereto.
Further, a circular limit protrusion 11210 is formed protruding from the middle of the surface of the tray body 1121 facing the tray 114, and correspondingly, a circular limit groove 1143 is formed recessed from the tray 114 facing the tray body 1121 and corresponding to the limit protrusion 11210. When the tray 114 is disposed on the turntable 112, the limiting protrusion 11210 is freely rotatably received in the limiting groove 1143 in the circumferential direction, so as to position the tray 114 and the turntable 112, and is used for limiting and guiding the rotation of the turntable 112.
Further, the lifting structure 11 further comprises a pressing plate 116, the pressing plate 116 is arranged on the tray 114 and fixedly connected with the base 110, and the tray 114 and the turntable 112 are stacked between the base 110 and the pressing plate 116 up and down. Wherein a through hole 1161 is formed in the middle of the pressing plate 116 for exposing the tray 114 at least partially disposed thereunder to accommodate the filter element 30. Meanwhile, a positioning rib 1163 is formed on the surface of the platen 116 facing away from the tray 114. The positioning ribs 1163 are circumferentially protruded at edges of the through holes 1161, and are used for positioning the filter element 30 accommodated in the through holes 1161.
Further, through grooves 1165 are formed in positions of the pressure plate 116 corresponding to the toggle switch 1123 along the circumferential direction, and the toggle convex points 11232 in the toggle switch 1123 are accommodated in and exposed out of the through grooves 1165 for a user to toggle.
Referring to fig. 5 and 6 together, the lifting structure 11 further includes a locking structure 118 disposed between the turntable 112 and the pressure plate 116 for locking the toggle switch 1123 in the sealing position, and the locking structure 118 includes a first self-locking portion 1181 disposed on one of the turntable 112 and the pressure plate 116 and a second self-locking portion 1183 disposed on the other of the turntable 112 and the pressure plate 116. The second self-locking portion 1183 is locked in the first self-locking portion 1181 when the turntable 112 rotates from the separating position to the sealing position relative to the platen 116, and is separated from the first self-locking portion 1181 when the turntable 112 rotates from the sealing position to the separating position relative to the platen 116.
The first self-locking portion 1181 is a self-locking recess provided on one of the turntable 112 and the platen 116, and the second self-locking portion 1183 is a self-locking protrusion provided on the other of the turntable 112 and the platen 116. In this embodiment, the first self-locking portion 1181 is a self-locking concave portion concavely formed on the outer surface of the stirring protruding point 11232, the second self-locking portion 1183 is a self-locking convex portion convexly arranged on the through groove 1165 facing the inner groove wall of the stirring protruding point 11232, and the shape of the self-locking concave portion is matched with the shape of the self-locking convex portion. Thus, when the toggle switch 1123 is operated to drive the rotary disc 112 to rotate from the separating position to the sealing position, the second self-locking portion 1183 is locked in the first self-locking portion 1181, so as to lock the rotary disc 112 in the sealing position relative to the pressure disc 116, prevent the rotary disc 112 from rotating, and further prevent the filter element 30 from falling when being located in the sealing position, so that a gap is formed between the filter element and the top wall of the purifying chamber. As shown in fig. 6, when the toggle switch 1123 is located at the right end of the through slot 1165, the tray 114 is located at a low position (i.e., a separation position), the first self-locking portion 1181 and the second self-locking portion 1183 are staggered and separated, and the turntable 112 can freely rotate relative to the platen 116 under the action of an external force; conversely, when the toggle switch 1123 is located at the left end of the through slot 1165, the tray 114 is located at a high position (i.e., a sealing position), the second self-locking portion 1183 is locked and received in the first self-locking portion 1181, and the turntable 112 is locked with respect to the platen 116.
It will be appreciated that in other embodiments, the location and configuration of the locking structure may be as desired, for example, the locking structure may be provided on mutually facing surfaces of the platen 116 and the turntable 112, and the locking structure may be a separable locking structure, such as a hook, without limitation.
