Description

Technical Field

[0001] The present invention relates to the technical field of air delivery equipment, and in particular to a pressure-expanding clean air delivery equipment. Background Art

[0002] In the prior art, the air outlets of household air supply equipment such as fans, air conditioners, air purifiers, and tower fans all have the form of changing the air outlet direction by an air guide plate or changing the position of the air outlet by swaying the body. The air outlet form is relatively simple and cannot reasonably distribute the range of the air blowing, resulting in waste of air and poor user experience.

[0003] In addition, the air inlet and outlet of traditional air supply equipment are designed to be open, and foreign objects such as dust and small insects can easily enter the air supply equipment and affect the working performance of the air supply equipment. Dust and other substances can easily adhere to the air inlet or outlet of the air supply equipment, affecting the effect of air intake or outlet. When users clean traditional air supply equipment, they usually need to disassemble it for manual cleaning, and the cleaning process is relatively troublesome. In addition, the dust removal device of the existing air supply equipment is generally only provided with a straight air inlet surface. The pressure generated by the airflow passing through the straight air inlet surface cannot be dispersed, and the large wind resistance will affect the purification performance of the dust removal device and the air intake and outlet effects of the air supply equipment.

[0082] A diffuser clean air delivery device, such as Figure 1 As shown, an air inlet mechanism 2000, an air duct body 3000 and a diffuser-type air outlet mechanism 1000 are provided. The air inlet mechanism 2000 is connected to the air inlet channel, the air outlet mechanism 1000 is connected to the air outlet channel, and the air duct body 3000 is connected between the air inlet channel and the air outlet channel.

[0083] Specifically, the air duct main body 3000 is provided with a fan, a wind wheel and a heating strip, the fan is assembled and connected with the wind wheel, and the wind wheel and the heating strip are assembled in the air duct main body 3000.

[0084] Specifically, an electrostatic dust removal module is provided at the air inlet of the air duct of the air inlet mechanism 2000. The electrostatic dust removal module has a dust removal device 2100 and a cleaning device 2200 for cleaning the dust removal device 2100. Figure 2The electrostatic dust removal module absorbs dust through the dust removal device 2100 to clean the air flow. The electrostatic dust removal module cleans the dust removal device 2100 through the cleaning device 2200 to ensure the adsorption performance of the dust removal device 2100.

[0085] The dust removal device 2100 of this embodiment is composed of multiple groups of grilles 2120. There is a gap between two adjacent groups of grilles 2120, and the gap between the grilles 2120 forms an air inlet surface. The arrangement of multiple groups of grilles 2120 has a larger air inlet area within the same space, and also reduces the resistance of the airflow to the dust removal device. The air inlet surface referred to in this technology refers to the direction in which the airflow enters the gap between the grilles as an air inlet surface.

[0086] The edge line of the windward side of the grille 2120 is defined as the outer edge line, and the outer edge line can be a straight line, such as Figure 3 The straight outer edge forms a flat air inlet surface, which facilitates the air flow to enter the dust removal device 2100.

[0087] There may also be a long thread segment in the outer edge, and the two endpoints of the long thread segment are connected by an arc, such as Figure 4 The existence of the long thread segment increases the length of the outer edge line, and the corresponding windward surface formed by the long thread segment is large, which can reduce the resistance generated when the wind enters.

[0088] In this embodiment, the multiple groups of grids 2120 are arranged at equal intervals. It should be noted that the multiple groups of grids can also be arranged at unequal intervals, which can be arranged by technicians according to actual needs.

[0090] The cleaning device 2200 in this embodiment is provided with a cleaning device body 2210 and a dust brushing part 2220 for being assembled in the gap between the grille 2120 and the grille 2120 of the dust removal device 2100, and the dust brushing part 2220 is assembled on the cleaning device body 2210. Figure 5 The dust brushing unit 2220 cleans the dust adsorbed on the dust removal device 2100 .

[0091] The dust brushing part 2220 in this embodiment is provided with a plurality of comb teeth 2221, and there are intervals between adjacent comb teeth 2221, and the plurality of comb teeth 2221 are used to be inserted into the gap of the dust removal grille 2120 of the dust removal module. The comb teeth 2221 move back and forth on the dust removal module to brush off the dust attached to the dust removal module.

[0092] The plurality of comb teeth 2221 in this embodiment are arranged in parallel at equal intervals. The comb teeth 2221 arranged in parallel at equal intervals can be better inserted into the gap of the dust removal grille 2120 of the dust removal unit.

[0093] It should be noted that the plurality of comb teeth 2221 may also be arranged at unequal intervals, and the arrangement of the comb teeth 2221 may be selected according to actual conditions.

[0094] In this embodiment, handles 2230 are provided at both ends of the cleaning device body 2210, and the handles 2230 are fixedly connected to the cleaning device body 2210. The handles 2230 are mounted on both sides of the body, and the user can manually drive the body to perform dust brushing cleaning operation through the handles 2230, and can manually clean the dust removal module without removing the windshield.

[0095] The cleaning device 2200 in this embodiment is further provided with a hand groove 2240, which is provided on the other side of the cleaning device body 2210 away from the dust brushing part 2220. The hand groove 2240 can facilitate the cleaning device 2200 to be disassembled for maintenance.

[0096] The cleaning device 2200 in this embodiment is further provided with a driving assembly 2250, and the driving assembly 2250 drives the cleaning device body 2210 and the dust brushing part 2220 to move as a whole.

[0097] The cleaning device 2200 in this embodiment is further provided with a track bracket 2260, the track bracket 2260 is provided with a sliding track 2261, the cleaning device body 2210 is slidably assembled on the sliding track 2261, the driving component 2250 is fixedly arranged relative to the track bracket 2260, the driving end of the driving component 2250 is fixedly connected to the cleaning device body 2210, and the connecting rod end of the driving component 2250 is connected to the track bracket 2260. Alternatively, the driving component 2250 is fixedly arranged relative to the device body, the driving end of the driving component 2250 is connected to the device body, and the connecting rod end of the driving component 2250 is fixedly connected to the track bracket 2260.

[0098] When the air inlet mechanism 2000 is working in a cleaning condition, the air inlet channel is closed, and the driving assembly 2250 drives the cleaning device body 2210 to move back and forth on the track bracket 2260, or the handle 2230 of the cleaning device 2200 is driven by manpower to move the cleaning device 2200, and the comb teeth 2221 of the dust brushing part 2220 also brush up and down in the gaps between the grilles 2120 of the dust removal device 2100 to brush off the dust attached to the grilles 2120. When the cleaning condition ends, the cleaning device 2200 stops working, the air inlet channel is opened, and the dust removal device 2100 starts to purify the air flow.

[0099] In the embodiment of the present invention, a diffuser-type clean air delivery device is provided with an electrostatic dust removal module at the air inlet of the air duct of the air inlet mechanism 2000. The electrostatic dust removal module has a dust removal device 2100 and a cleaning device 2200 for cleaning the dust removal device 2100. The dust removal device 2100 is provided with a plurality of air inlet surfaces, and the outer edges of the air inlet surfaces are not connected in a straight line. The presence of a plurality of air inlet surfaces effectively expands the air inlet area. The electrostatic dust removal device absorbs dust through the dust removal device 2100, and plays a role in cleaning the airflow. The electrostatic dust removal module cleans the dust removal device 2100 through the cleaning device 2200 to ensure the adsorption performance of the dust removal device 2100. The air inlet mechanism 2000 of the present embodiment can be cleaned without disassembling any components, and the cleaning process is simple and easy to operate.

[0100] Example 2.

[0101] A pressure-expanding clean air delivery device, the other features of which are the same as those of Example 1, except that it also has the following technical features: the dust removal device has air inlet surfaces in multiple directions. The airflow can enter the air inlet channel from multiple directions, which reduces the pressure of the airflow on the dust removal device and also has a larger air inlet area.

[0102] Example 3.

[0103] A pressure-expanding clean air delivery device, the other features of which are the same as those of embodiment 1 or embodiment 2, except that: the long thread segments in this embodiment are arranged to be connected by multiple broken lines, such as Figure 6 It should be noted that the long thread segments can also be connected in a manner of arcs and broken lines interlaced, and the connection manner is not limited to one and can be determined by the technicians according to the specific situation.

[0104] The existence of the long thread segment increases the length of the outer edge line, and the corresponding windward surface area formed by the long thread segment is large, which can reduce the resistance generated when the wind enters.

[0105] Example 4.

[0106] A diffuser clean air delivery device, such as Figures 7 and 8 As shown, the air outlet mechanism 1000 is provided with an air guide plate 100, the inner surface of the air guide plate 100 is an air guide surface, and the air guide surface is a curved surface structure with a central protrusion. The air guide surface gradually transitions to the edge area.

[0107] The wind blown out by the air outlet device gradually transitions from the center part along the inclined wall to the edge area through the curved wind guide surface, which can produce a horizontal wind outlet effect. At the same time, in conjunction with the air outlet channel, the direction of the wind outlet can be changed by changing the relative distance of the air guide plate 100.

[0108] Specifically, the air guide plate 100 is mounted at the air duct outlet, one end of the air duct outlet has a small diameter and the other end has a large diameter, and the end with the large diameter is where the airflow is discharged from the air duct. The air duct outlet continuously transitions from the end with the small diameter to the end with the large diameter.

[0109] The pressure-expanding clean air delivery device of the present invention is as follows: Fig. 9 As shown, the air outlet mechanism 1000 is also provided with a main frame 200 for being installed at the air duct outlet and a six-dimensional driving mechanism 300, the air guide plate 100 is installed on the main frame 200, the six-dimensional driving mechanism 300 is installed between the main frame 200 and the air guide plate 100, and the six-dimensional driving mechanism 300 drives the air guide plate 100 to move in the front-back, left-right or up-down directions.

[0110] The six-dimensional driving mechanism 300 drives the air guide plate 100 to move in the front-to-back, left-to-right or up-and-down directions, resulting in a change in displacement direction. This can change the diffusion depth of the air guide plate 100 at the air outlet channel, thereby achieving the effect of changing the air outlet range.

[0111] It should be noted that the wind direction when the air flows out from the air duct outlet is defined as the front, and the wind direction when the air flows out in the opposite direction to the front is defined as the rear; the direction when the air outlet is blocked by the wind shield and moves to the left or right is defined as the left and right direction; the direction when the air outlet is blocked by the wind shield and moves upward or downward is defined as the up and down direction.

[0112] Furthermore, the main frame 200 is provided with an air duct interface for connecting to the air duct outlet, and the six-dimensional driving mechanism 300 is assembled on the air duct interface.

[0113] The six-dimensional driving mechanism 300 in this embodiment is provided with a support frame 340, a left-right driving mechanism 310, an up-down driving mechanism 330 and a front-back driving mechanism 320, and the left-right driving mechanism 310, the up-down driving mechanism 330 and the front-back driving mechanism 320 are respectively assembled on the support frame 340.

[0114] Specifically, Fig.10 As shown, the left and right driving mechanism 310 is provided with a first driving motor 311 and a first rotating wheel 312;

[0115] The first drive motor 311 is fixed to the air guide plate 100 , and the motor shaft of the first drive motor 311 is fixedly connected to the first rotating wheel 312 . The first drive motor 311 drives the first rotating wheel 312 to rotate. The support frame 340 is fixed with a first rack 341 , and the first rack 341 is meshed with the first rotating wheel 312 .

[0116] During the actual air outlet process, the first driving motor 311 rotates, driving the first rotating wheel 312 to rotate left and right on the first rack 341, thereby causing the air guide plate 100 to change its left and right displacement, thereby realizing the left and right air outlet modes to flap back and forth around the user, thereby improving the user's comfort.

[0117] In the diffuser-type clean air delivery equipment of the present invention, the left and right driving mechanisms 310 in the air outlet mechanism 1000 are also provided with a limiting wheel 313, which is coaxially connected to the first rotating wheel 312, and the radius of the limiting wheel 313 is greater than the radius of the first rotating wheel 312, and the limiting wheel 313 fits the side wall of the first rack 341.

[0118] It should be noted that the limiting wheel 313 is used to fit with the first rack 341 to ensure the stability of the first rotating wheel 312 during movement.

[0119] In this embodiment, the side of the wind deflector 100 close to the air duct outlet is the inner surface of the wind deflector, and the side of the wind deflector 100 facing away from the air duct outlet is the outer surface of the wind deflector. The first drive motor 311 can be fixed to the inner surface of the wind deflector, or the outer surface of the wind deflector, and the motor shaft of the first drive motor 311 passes through the through hole 110 provided on the wind deflector and is fixedly assembled with the first rotating wheel 312.

[0120] In this embodiment, the first drive motor 311 is fixedly mounted on the outer surface of the windshield. In actual design, those skilled in the art can set the position of the first drive motor 311 according to actual conditions, which will not be described in detail here.

[0121] Specifically, the support frame 340 is provided with a second fixed portion 342, front and rear sliding sleeves 343, front and rear sliding rods 344 and a third fixed portion 345, the front and rear sliding sleeves 343, the front and rear sliding rods 344, the second fixed portion 342 is fixed to the air duct outlet, the front and rear sliding sleeves 343 are fixedly connected to the second fixed portion 342, the front and rear sliding rods 344 are slidably assembled on the front and rear sliding sleeves 343, and the third fixed portion 345 is fixedly connected to the front and rear sliding rods 344.

[0122] Specifically, the front and rear driving mechanism 320 is provided with a second driving motor 321 and a second rotating wheel 322. The second driving motor 321 is fixed to the second fixed part 342, and the second driving motor 321 drives the second rotating wheel 322 to rotate. The second rotating wheel 322 is engaged with the second rack 3471 fixed to the third fixed part 345.

[0123] In the actual air outlet process, the second driving motor 321 fixed to the second fixed part 342 rotates, driving the second rotating wheel 322 shaft to rotate, so that the second rack 3471 meshing with the second rotating wheel 322 rotates back and forth, and when the second driving motor 321 drives the air guide plate 100 to move forward, the air duct outlet becomes wider, the wind speed of the air outlet gradually decreases, and the air is discharged along the edge area of ​​the air outlet, and finally tends to be discharged in a vertical direction; when the second driving motor 321 drives the air guide plate 100 to move backward, the air duct outlet becomes narrower, the wind speed of the air outlet is large, and the air is discharged along the air guide surface, and gradually tends to be discharged in a horizontal direction.

[0124] By moving the air guide plate 100 forward and backward, air supply coverage within a range of 180° in the air outlet direction is achieved, thereby achieving a swinging air outlet effect.

[0125] The support frame 340 of this embodiment is provided with an upper and lower sliding rod 346 and an upper and lower sliding sleeve 347 ; the third fixed portion 345 is fixedly connected to the upper and lower sliding sleeve 347 , and the third fixed portion 345 is slidably assembled on the upper and lower sliding sleeve 347 .

It should be noted that the two sets of left and right drive mechanisms 310 can simultaneously drive the first rotating wheel 312 to move left and right through the first driving motor 311, which can cause the wind guide plate 100 to change its displacement in the left and right directions, thereby generating comfortable wind.
