Description

Technical Field

[0001] The utility model relates to a blowing and drying device, in particular to a blowing and drying device used in the field of air drying of vehicle mats. Background Art

[0002] The existing blowing and drying device has the following defects:

[0003] 1. After the fan blows out the air, the wind direction after passing through the diverter is at an angle of 90° to the wind direction of the fan. After the air blows out, it turns 90° after the flow channel corner. The wind directly hits the corner pipe wall vertically, resulting in large air volume and pressure losses, low blowing and drying efficiency, and cannot meet actual use requirements;

[0004] 2. After the fan discharges air, it passes through the air duct and is discharged from the air outlet of the air duct. The air volume and air pressure accumulate in the air duct, and the wind cannot be effectively guided to the air outlet, which increases the air volume and air pressure loss again and makes it difficult to meet the demand;

[0005] 3. The motion drive mechanism that drives the fan to move mostly uses a synchronous belt. When using a high-power and heavy-duty fan, the synchronous belt is difficult to drive the fan to move, and its operation is unstable and the driving force is small.

[0006] The above problems seriously affect the user experience and there is room for improvement. Utility Model Content

[0007] The blowing and drying module and device provided by the present technical solution can increase the air pressure and air volume of the hot air outlet, effectively improve the blowing and drying efficiency, and bring a good user experience.

[0008] To achieve the above-mentioned purpose, the technical solution is the following blowing and drying module, characterized in that: it includes a gas working module, a diverter, and an air outlet; the gas working module includes a gas generator and a heating component, the gas generator, the diverter and the air outlet are fluidly connected in sequence, the gas generator generates fluid that passes through the heating component to generate hot air, and the diverter diverts the hot air to the air outlet; the angle between the diverted hot air flow direction of the diverter and the air outlet flow direction of the gas generator is greater than 90° and less than 180°, and the air outlet section of the air outlet has a guide slope or a guide curve.

[0009] In the technical solution constructed as above, the angle between the diverted hot air flow direction of the diverter and the outlet air flow direction of the gas generator is greater than 90° and less than 180°. The gas generator generates hot air after the fluid passes through the heating component. The diverter diverts the hot air to the air outlet. The hot air does not directly turn 90° after the diversion, but flows out smoothly from the hot air diversion point. The collision and obstruction between the fluid and the corner are small, and the air volume and pressure loss of the hot air is very small, ensuring that the air volume and pressure of the air outlet from the gas generator are basically not lost. After the air is diverted from the diverter, it flows to the air outlet. Because the air outlet section of the air outlet has a guiding slope or a guiding curve, the hot air can be guided from the guiding curve or the slope and then effectively guided out from the air outlet of the air outlet, so that the hot air will not accumulate in the air duct, further reducing the air volume and pressure, so that the air outlet air volume and pressure meet the requirements, thereby improving the blowing and drying efficiency of the mat.

[0010] In the present technical solution, preferably, a guide is further connected between the diverter and the air outlet, and the guide causes a secondary change in the wind direction of the hot air.

[0011] In the technical solution constructed as above, since a guide is connected between the diverter and the air outlet, the second change in wind direction is conducive to blowing and drying the mat in a direction perpendicular to the mat, and the force acting on the mat is large, thereby improving the blowing and drying efficiency of the mat. Furthermore, after the diverter fluid is connected to the guide, the diverter channel of the diverter can be shortened, thereby reducing the volume and length of the blowing and drying module.

[0012] In the present technical solution, it is preferred that the cross-sectional area of ​​the air outlet duct of the air outlet section changes from large to small.

[0013] In the technical solution constructed as above, the cross-sectional area of ​​the air outlet duct of the air outlet section changes from large to small, and the air outlet duct of the air outlet section presents a three-dimensional shape of an inverted cone or an inverted curved cone. The air outlet duct gradually shrinks, which is conducive to guiding and gathering wind, reducing air outlet obstacles, and increasing air outlet pressure.

[0017] In the technical solution constructed as above, since the gas generator is fixed on the reciprocating motion mechanism, when the control unit controls the reciprocating motion mechanism to move back and forth, it can control the gas generator to move back and forth for blowing air. When the blowing and drying module is used to blow and dry the mat, the air outlet area can cover the surface of the mat, achieving full coverage without dead corners.

[0018] In the present technical solution, the reciprocating motion mechanism preferably includes a rack and pinion drive mechanism and a sliding assembly, the rack and pinion drive mechanism is driven and connected to the sliding assembly or the gas generator, and the control unit communicates with the rack and pinion drive mechanism and controls the rack and pinion drive mechanism to drive the sliding assembly and the gas generator to move back and forth in a straight line.

[0019] In the technical solution constructed as above, since the rack and pinion drive mechanism is connected to the sliding component or the gas generator, and the gas generator is fixed on the reciprocating motion mechanism, when the control unit controls the rack and pinion drive mechanism to drive the sliding component or the gas generator, the sliding component and the gas generator will simultaneously and synchronously perform linear motion back and forth. The use of the rack and pinion drive mechanism will be more stable, have large power transmission, long service life, stable operation, and can ensure a constant transmission ratio, and has a large load-bearing capacity. Especially when the weight of the gas generator is large, it can carry a large weight and move smoothly.

[0020] In the present technical solution, the gear rack drive mechanism preferably includes a gear, a rack and a motor, the gear is meshed with the rack, the gear is rotationally connected with the motor, and the control unit communicates with the motor and controls the motor to drive the gear to rotate.

[0021] In the technical solution constructed as above, the rack and pinion drive mechanism includes a gear, a rack and a motor, the gear is meshed with the rack, and the gear is rotationally connected with the motor. When the control unit communicates with the motor and controls the motor to drive the gear to rotate, the rotation of the gear itself is converted into a linear motion of the gear on the rack, thereby realizing the back-and-forth linear motion of the gas generator. The transmission is smooth, and the speed of the linear motion of the gas generator can be controlled by controlling the speed of the motor through the control unit to meet actual needs.

[0022] The present technical solution also provides a blowing and drying device, which is characterized in that it includes a supporting module, an air outlet, a reciprocating motion mechanism, a gas working module and a control unit; the gas working module includes a gas generator and a heating assembly, the gas generator is fluidly connected to the air outlet, the supporting module is used to place a mat, the reciprocating motion mechanism includes a gear rack driving mechanism and a sliding assembly, the gear rack driving mechanism is transmission-connected to the sliding assembly or the gas generator, the gas generator is fixed on the sliding assembly, the control unit communicates with the gear rack driving mechanism and controls the gear rack driving mechanism to drive the sliding assembly and the gas generator to move back and forth in a straight line.

[0023] In the technical solution constructed as above, since the gas generator is fixed on the sliding component, the rack and pinion drive mechanism is connected to the sliding component or the gas generator, when the control unit controls the rack and pinion drive mechanism to drive the sliding component or the gas generator, the gas generator and the sliding component can move back and forth in a straight line, and the gas generator generates hot air through the heating component. When the cleaned mat is placed in the supporting module, the hot air moves back and forth on the surface of the mat to cover the entire surface of the mat to blow and dry it; the use of a rack and pinion drive mechanism will be more stable, have large power transmission, long service life, stable operation, and can ensure a constant transmission ratio, and has a large load-bearing capacity. Especially when the weight of the gas generator is large, it can carry a large weight and move smoothly.

[0024] In the present technical solution, it is preferred that the tooth surface of the rack is not arranged upward, and the tooth surface is perpendicular to the plane where the sliding component is located.

[0025] In the technical solution constructed as above, since the tooth surface of the rack is not arranged upward, the tooth surface is perpendicular to the plane where the sliding assembly is located, and the tooth surface is perpendicular to the plane where the slider rail linear motion mechanism is located, and is not arranged upward, it can prevent dust and sand from falling into the teeth of the rack during the blowing and drying device, avoid the movement of the gear rack from being disturbed by dust and sand, and ensure that the movement of the gear rack is smooth without interference.

[0027] In the technical solution constructed as above, a boss is provided at the bottom of the box body, and the reciprocating motion mechanism is fixed on the boss. The boss at the bottom of the box body plays a good supporting role for the reciprocating motion mechanism, and the boss raises the reciprocating motion mechanism. The gas generator is fixed on the sliding component in the reciprocating motion mechanism. When the gas generator generates hot air through the heating component to blow and dry the wet pad in the support module, the moisture generated will sink downward, reducing the moisture flow to the gas generator and the heating component, especially heavier moisture may flow to the heating component, and the heating component will be connected to the electrical components. Such a setting can reduce the influence of moisture on the leakage and short circuit of the heating component. Furthermore, the position of the gas generator is raised in the height direction of the box body, and the air outlet will not interfere with the reciprocating motion mechanism.

[0046] For the purpose of facilitating understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the accompanying drawings described herein. The embodiments disclosed herein are not intended to be exhaustive or to limit the present invention to the precise form disclosed. Rather, the embodiments are selected and described so that other technicians in the field can make use of these teachings. Therefore, it is not desired to limit the scope of the claimed utility model. The present utility model includes any changes and further modifications to the illustrated apparatus and the described method that would be generally understood by a technician in the field to which the present utility model belongs, as well as further applications of the principles in the present utility model. It should be noted that, for ease of description, the following description will only be based on the example of a mat inside a vehicle being used for air drying in the air drying device of the present utility model, and the mat is a foot mat under the seat in the vehicle, but it is not limited to this.

[0047] See also Figure 1 It is a side view stereoscopic diagram of the blowing and drying module in the blowing and drying equipment in the prior art. After the fan 4 discharges air, the fluid generated by the fan is diverted to the air duct 1 and the air duct 3 on both sides through the T-shaped tube. The T-shaped tube is a right-angle three-way tube. After the air is discharged, the T-shaped tube is diverted at the straight flow tube, and a 90° turn occurs after the corner. The wind directly hits the corner pipe wall vertically, and then turns 90° again after connecting to the air duct. At the second corner, it turns 90° again, and the fluid directly hits again. The fluid encounters great obstacles, and the air volume and air pressure losses are large. The blowing and drying efficiency is low and cannot meet actual use requirements.

[0048] Furthermore, after the air is discharged from the fan, it passes through the air duct 1 and the air duct 3, and is discharged from the air outlet of the air duct. The air volume and air pressure accumulate in the air duct, and the wind cannot be effectively guided to the air outlet, which again increases the air volume and air pressure loss. The motion drive mechanism 5 that drives the fan 4 to move adopts a synchronous belt. When a high-power and heavy-duty fan is used, the synchronous belt is difficult to drive the fan to move, and its operation is unstable and the driving force is small.

[0049] Figure 2-Figure 10 The diagram shows a schematic diagram of the blowing and drying device 1000 and the blowing and drying module in the technical solution example 1, see Figure 2 and Figure 3 The air drying device 1000 includes a gas generator 10, a cover 20, a flow divider 30, an air outlet 40, a box 50, a universal wheel 60, and a cover 70. The universal wheel 60 is fixedly installed on the bottom surface of the box 50, and can be used to push the air drying device 1000 to move, which is convenient for turning. The universal wheel 60 and the ground are in rolling friction, which has the effect of saving effort. The cover 70 can be covered on the top of the box 50 and is hinged to the upper edge of the rear side plate of the box 50 (using a hinge connection). When the air outlet drying device 1000 is used to blow and dry the cleaned mat, it can be placed on the top of the box to prevent dust and debris from falling into the box. The front side plate of the cover 70 also has a handle 701, and the handle 701 can be used to flip and cover the cover 70, which is convenient and quick.

[0050] See also Figure 2 and Figure 6 The left and right side panels of the box body 50 are also provided with ventilation places 80. When the gas generator 10 is working, air can be sucked out from the ventilation places 80 on both sides and enter from the air inlet 102 of the gas generator 10, and flow out from the air outlet 104 to generate fluid. The ventilation places 80 on both sides can also be equipped with shutters to prevent dust and the like from entering, and moisture-absorbing cotton can also be installed to prevent heavy moisture from entering when sucking air from the outside and affecting the operation of the heating component 150, thereby avoiding the occurrence of leakage. The air inlet 102 of the gas generator 10 can also be provided with a shielding piece 103, and the shielding piece 103 can be moved to adjust the air inlet area of ​​the air inlet 102, thereby adjusting the air outlet volume of the gas generator 10.

[0051] See also Figure 3 and Figure 4A slide 110 is provided near the edge of the left side plate of the box body 50. The slide 110 is composed of a first rib 111 and a second rib 112 protruding from the left side plate. The support module 100 is slidably arranged in the slide 110. The first rib 111 and the second rib 112 limit the support module 50 to prevent it from moving left and right. In addition, the support module 100 can be easily placed in the slide from the top of the box body 50. In terms of placement and placement, it is easy to install. After the cleaned mat 90 is placed in the support module 100, the blowing and drying device 1000 can be started to blow and dry it, which brings great convenience. In addition, the bottom plate of the support frame is hollow, and the water generated when the mat 90 is blown and dried can flow out from the bottom without accumulating water. The specific shape and structure of the support module 90 is specifically disclosed in CN220541591 U, which is introduced into this article and will not be repeated.

[0052] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Fig.17 The blowing and drying equipment 1000 also includes a control unit. The gas generator 10 and the heating component 150 constitute a gas working module. The gas generator 10, the diverter 30 and the air outlet 40 are fluidically connected in sequence. The gas generator 10 generates fluid that passes through the heating component 150 to generate hot air. The diverter diverts the hot air to the air outlet 40. There are two air outlets 40, which are arranged on both sides of the reciprocating motion mechanism respectively.

[0053] See also Figure 5 and Figure 6 Specifically, the reciprocating mechanism includes a gear rack drive mechanism 120 and a sliding assembly 130, the gear rack drive mechanism 120 is in transmission connection with the sliding assembly 130, the control unit communicates with the gear rack drive mechanism 120 and controls the gear rack drive mechanism 120 to drive the sliding assembly 130 to move back and forth linearly, and move back and forth linearly with the gas generator, the gas generator 10 is fixed on the sliding assembly 130, when the sliding assembly 130 is driven to move back and forth linearly, the gas generator 10 moves back and forth linearly synchronously with the sliding assembly 130. As an alternative, the gear rack drive mechanism 120 can also be in transmission connection with the gas generator 10, so that the gas generator 10 is fixed on the sliding assembly 130, and the gas generator 10 can also be driven to move back and forth linearly synchronously with the sliding assembly.

[0054] See also Figure 4 and Figure 5A boss 52 is provided on the bottom 51 of the box body 50 , and the reciprocating motion mechanism is fixed on the boss 52 . Specifically, the bottom plate 140 of the frame 140 is fixed on the boss 52 (fixed by screws, the screws are not shown in the figure), and the boss 52 at the bottom of the box body 50 plays a good supporting role for the reciprocating motion mechanism. The boss 52 raises the reciprocating motion mechanism, and the gas generator 10 is fixed on the sliding component 130 in the reciprocating motion mechanism. When the gas generator 10 generates hot air through the heating component 150 to blow and dry the wet pad 90 in the support module 100, the moisture generated will sink, reducing the moisture flow to the gas generator 10 and the heating component 150, especially heavier moisture may flow to the heating component 150, and the heating component 150 will be connected to the electrical components. Such a setting can reduce the influence of moisture on the leakage short circuit of the heating component 150. Furthermore, the position of the gas generator 10 is raised in the height direction of the box body 50, and the air outlet 40 will not interfere with the reciprocating motion mechanism.

[0055] The rack and pinion drive mechanism 120 includes a rack 121, a gear 122, a fixed plate 124 and a motor 123. The rack 121 is vertically fixed on the convex strip 141 of the bottom plate 142 of the frame 140. The gear 122 is meshed with the rack 211. The motor 123 is fixed on the fixed plate 124 and is also rotatably connected to the gear 122. The sliding assembly 130 includes a slide rail 131 and a slider 132. The slider 132 is slidably connected to the slide rail 131. The slide rail 131 is fixed on the bottom plate 142 of the frame 140. Two slide rails 131 are arranged on the left and right sides. The sliders 132 also correspond to the left and right sides. The fixed plate 124 is fixed on the slider 132 (fixed by screws, and the screws are shown in the figure). The base of the gas generator 10 is also fixed on the fixed plate 124.

[0056] Since the base of the gas generator 10 is fixed on the fixed plate 124, the fixed plate 124 is fixed on the slider 132, and the motor 123 is fixed on the fixed plate 124, when the control unit communicates with the motor 123 and controls the motor 123 to drive the gear 122 to rotate, the rotation of the gear 122 itself is converted into the linear motion of the gear 122 on the rack 121, thereby driving the gas generator 10, the fixed plate 124, and the motor 123 to synchronously drive smoothly, and the speed of the linear motion of the gas generator can be controlled by controlling the speed of the motor through the control unit to meet the actual needs. The gas generator 10 generates hot air through the heating component 150. When the cleaned mat 90 is placed in the support module 100, the hot air moves back and forth on the surface of the mat 90 to cover the entire surface of the mat 90 and blow it dry; the use of the gear rack drive mechanism 120 drive will be more stable, transmit large power, have a long life, work stably, and can ensure a constant transmission ratio, and bear a large load, especially when the weight of the gas generator 10 is large, it can bear a large weight and move smoothly.

[0057] Furthermore, the tooth surface of the rack 121 is not set upward, and the tooth surface of the rack 121 is perpendicular to the plane where the sliding component 130 is located, which can prevent dust and sand from falling into the tooth surface of the rack 121 during blow drying, avoid the movement of the gear rack from being disturbed by dust and sand, and ensure that the movement of the gear rack is smooth without interference.

[0058] See also Figure 2 and Figure 7 When the control unit communicates with the rack and pinion drive mechanism 120 in the reciprocating mechanism and controls the driving gas generator 10, the fixed plate 124 and the slider 132 to move back and forth synchronously in a straight line, the two ends of the bottom plate 142 of the frame 140 are also fixed with sensor 1 160 and sensor 2 170. The control unit is electrically connected to the sensor 160 and the second sensor 170. When the rack-and-pinion drive mechanism 120 drives the blower 40 to move from the first position B1 at the left end to the second position B2, when the blower 40 is at the first position B1, the sensor 160 detects that the blower 40 has reached the position, and then sends a signal to the control unit. The control unit drives the motor 123 to rotate forward (opposite to the previous direction), and the drive module 10 drives the blower 40 to move to the second position B2. At this time, the sensor 170 detects that the blower 40 has reached the position, and then sends a signal to the control unit. The control unit drives the motor 123 to reverse (opposite to the previous direction), and the rack-and-pinion drive mechanism 120 continues to drive the blower 40 to move in the opposite direction, thus forming a left-right linear reciprocating motion state. In this way, the reciprocating motion is completed by detecting the positions of the two ends through two sensors to blow and dry the mat 90. The sensor can be a photoelectric sensor, an optical sensor, a magnetic Hall sensor, or a proximity sensor, etc. The present invention does not limit the type of sensor. In a specific embodiment of the present invention, the sensor may be a diffuse reflection photoelectric sensor, model BX-552, a metal proximity switch sensor, model PL-05N, or a through-beam photoelectric sensor, model E3F-20C1.

[0059] See also Figure 6 and Figure 8The air outlet 104 of the gas generator 10 is fluidly connected to the diverter 30, and the diverter is fluidly connected to the air outlet 40 after diversion. The two heating components 150 are respectively installed in the first diverter channel 31 and the second diverter channel 33, thus forming a blowing and drying module. The diverter 40 adopts a three-way pipe, and its main air inlet 31 is connected to the air inlet 104 of the fan gas generator 10. The first diverter channel 31 and the second diverter channel 33 after diversion are respectively connected to the two air outlets 40. The angle A between the flow direction of the hot air diverted by the diverter and the outlet flow direction of the gas generator is greater than 90° and less than 180°, preferably between 110-155°, and the optimal angle is 135°. Of course, it can be 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129°, 130°, 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, 140°, 141°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°, 156°, 157°, 158°, 159°, 160°, 161°, 162°, 163°, 164°, 165°, 166°, 167°, 168°, 169°, 170°, 171°, 172°, 173°, 174° 29°, 130°, 131°, 132°, 133°, 134°, 136°, 137°, 138°, 139°, 140°, 141°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, etc. The angle between the diversion direction after diversion and the horizontal direction OX is an acute angle, and is not perpendicular to the horizontal direction OX. The gas generator 10 generates hot air after the fluid passes through the heating component 150, and the diverter 30 flows out smoothly from the hot air diversion point. The collision and obstruction between the fluid and the corner are small, and the air volume and pressure loss of the hot air is very small, ensuring that the air volume and pressure of the air outlet from the gas generator 10 are basically not lost.

[0060] Return to reference 4, continue reading Figure 8 The air outlet direction of the gas generator 10 also forms a certain angle with the horizontal direction OX, and the angle is approximately between 0-10°. This ensures that after the diverter 30 is connected to the air outlet 40, the distances from the air outlet 40 to the cushions 90 on both sides are equal, and the air outlet 10 will not interfere with the frame installed on the boss 52. At the same time, the width of the blowing and drying device is shortened, and the lengths of the first diverter channel 32 and the second diverter channel 33 of the diverter 30 are also shortened, that is, the length of the entire blowing and drying device is shortened, saving materials and thus saving costs.

[0061] See also Fig. 9 The heating component 150 includes a heating wire 151 and a frame 152. The heating wire 151 is spirally wound on the outer circumference of the frame 152. The heating wire is generally about 2 mm in diameter. Because of its small diameter, it reduces wind resistance and has high heat conversion efficiency. Relatively speaking, the heating tube generally has a larger diameter and poses greater resistance to wind. The PTC heating method generally has low power and is difficult to install. The frame 102 adopts a cross-shaped frame and is placed vertically to further reduce wind resistance and reduce the loss of wind pressure and air volume.

[0062] See also Fig.10 The heating assembly includes a flow diverter 30 that diverts the wind to the air outlet 40.

[0063] The air outlet section of the air outlet 40 has a guiding slope 41 (or a guiding curved surface), and the hot air can enter the air inlet 42 of the air outlet 40 and be effectively guided out from the air outlet 43 after being guided by the guiding slope 41 or the guiding curved surface. The hot air will not accumulate in the air duct, further reducing the air volume and pressure, so that the air volume and pressure of the outlet air meet the requirements, and improving the air drying efficiency of the mat. The air outlet 43 adopts a narrow and long rectangular air outlet, and the hot air can flow out smoothly to form a long strip of hot air belt to blow and dry the mat.

[0064] The cross-sectional area of ​​the air outlet section of the air outlet 40 changes from large to small, and the air outlet section presents an inverted cone or an inverted curved cone three-dimensional shape. The air outlet gradually shrinks, which is conducive to guiding and gathering air, reducing air outlet obstacles, and increasing air outlet pressure. The area of ​​the air inlet 42 of the air outlet 40 is larger than the area of ​​the air outlet 43, so as to ensure that the final air outlet pressure is greater than or equal to the air outlet pressure of the gas generator 10. In this way, when selecting the gas generator 10, a gas generator 10 with a smaller power can also meet the requirements, saving electricity. If the final air outlet area is greater than or equal to the air outlet area of ​​the gas generator 10, the air outlet pressure is reduced, and a gas generator 10 with a larger power needs to be selected to meet the requirements, which requires a larger amount of electricity.

[0065] The control unit also communicates with the gas generator 10 and the heating component 150 and controls the actions of the gas generator and the heating component 150. It can realize the start and stop control, air volume and air pressure control of the gas generator 10, and the heating temperature control of the heating component 150. The electronic control is fast and convenient to meet actual needs.

[0066] Figures 11 to 16 This is Example 2 of the blowing and drying device 2000 of the present technical solution, see Fig.11 , Fig.12 and Fig.14 The flow divider 300 includes a main flow channel 301, a first flow divider channel 302, and a second flow divider channel 303. The flow divider 300 also includes a guide, and the guide includes a first guide 304 and a second guide 305. The angle between the main flow channel of the flow divider and the first flow divider channel is B. After passing through the first guide 304, the wind outlet angle changes slightly. After passing through the second guide 305 again, the hot air direction changes again.

[0067] After the wind direction is changed twice, it is beneficial to blow and dry the mat in a direction perpendicular to the mat, that is, after the wind direction is changed twice, it is perpendicular to the vertical direction OY, and the force acting on the mat is large, which improves the efficiency of blowing and drying the mat. Moreover, after the diverter fluid is connected to the guide, the first diverter channel 302 and the second diverter channel 303 of the diverter 300 can be shortened, reducing the volume and length of the blowing and drying module and the blowing and drying device. The heating component 1500 can also be installed in the mainstream channel 301 of the diverter 300, so that only one heating component is needed to generate hot air after diversion, saving the number of parts and thus saving costs.

[0068] See also Fig.13 and Fig.14 , a boss 520 is provided at the bottom of the box, and the rack and pinion drive mechanism is fixed on the boss 520, specifically, the non-tooth surface of the rack 1202 in the rack and pinion drive mechanism is fixed on the boss 520, and the tooth surface is parallel to the plane where the sliding assembly 1300 is located, that is, the tooth surface is completely arranged upward. The sliding assembly 1300 includes a mounting member 1301, a slider 1302 and a guide bar 1303. The guide bar 1303 is two opposite guide bars on both sides. The guide bar passes through the mounting member 1301 and is fixed. The mounting member 1301 is fixed on the boss 520 in the box, and the slider 1302 also passes through the guide bar 1303. In this way, the sliding mode of the guide bar slider will be smoother. Ball bearings can be added between the slider 1320 and the guide bar 1303 to further improve the smoothness. Compared with the method in Example 1, the sliding assembly slides more smoothly, does not require a frame for installation, and only requires two mounting members 1301, which saves materials and thus saves costs. See Fig.15 and Fig.16 The air outlet device 400 includes an air inlet section 4001 and an air outlet section 4002. Hot air enters from the air inlet 4004, passes through the air inlet section 4001 with a gradually increasing cross-sectional area, and then passes through the air outlet section 4005 with a gradually decreasing cross-sectional area and flows out from the air outlet 4001. The two-stage gradual air outlet sections make the air outlet space larger, and the air volume accumulates more in the space, so the air volume is increased, which further improves the efficiency when blowing and drying the mat.

[0069] The gas generator 10 generates hot air after passing through the heating component 150. The heating component can be connected to the air inlet or outlet of the gas generator and the air outlet duct after the air is discharged. The gas generator preferably adopts an air pump, a fan or a gas compressor. When other generators adopt a fan, for example, a cross-flow fan, a centrifugal fan, a comb fan, a cross-flow fan, a multi-blade fan, a mixed flow fan and a vortex fan can be used. The fan can adopt the fan structure in Panasonic's JP1977072908A, JP1984008679B2, JP1985059491 B2, JP1983012694U, JP1988010319B2, JP1989008199B2, JP1993080600B2, JP1994056155B2, JP6051403B2, JP7213415B2 and other patents. The specific structure is discussed in detail in the patent and will not be repeated here. The fan in this technical solution adopts a CZR-370 model fan with an air volume of 840 cubic meters per second, a weight of about 11 kilograms, a rotation speed of 2850 revolutions per minute, and a wind pressure of 2100 Pa.

[0070] The air outlet can be made of high temperature resistant material to prevent the hot air with high temperature from entering and causing thermoplastic deformation of the shell. Preferably, PVC material can be used, which is easy to process and heat resistant. The temperature of the hot air here generally cannot exceed 100°, otherwise the mat may be scorched during drying. As another alternative embodiment, the air duct can also be made of metal material, such as stainless steel, cast aluminum or aluminum alloy.

[0071] See also Fig.17, is the logic control diagram of the air drying device of the technical solution. The control unit sets the air drying time of the air outlet, for example, 3 minutes. Within 3 minutes, the air outlet will move back and forth at a certain speed to blow and dry the mat, and automatically stop after the time is up. The air outlet also includes a temperature sensor and a humidity sensor. The temperature sensor and the humidity sensor detect the temperature and humidity values ​​of the mat in real time, and transmit the detected temperature and humidity values ​​of the mat to the control unit for comparison with the temperature threshold and the humidity threshold to determine the moisture and humidity on the surface of the mat to control the start and stop of the air drying device. The control unit can also control the start and stop of the gas generator, the output power of the heating component to control the hot air outlet temperature; the control unit is operated through an external controller, and the controller can be an operation display panel and button on the top or front side panel of the box body 1 of the blowing and drying device. The operation display panel can display the air temperature, air volume and air pressure, and the blowing and drying setting time. The power button can operate the start and stop of the blowing and drying equipment. Buttons or knobs can be used. The temperature adjustment and air volume adjustment keys can be operated to adjust the temperature and air volume respectively. The operation display panel can adjust the temperature and air volume steplessly, so that the required air outlet temperature and air volume can be adjusted in any temperature range and air volume range specified by it to meet the needs of blowing and drying different types of mats and mats with different moisture content, or the control panel can adjust the air outlet temperature and air volume in multiple gears, such as "setting high, medium and low gears" for different scenes, with strong applicability. The operation panel uses a liquid crystal touch screen to display the temperature and air volume values, which is intuitive and clear at a glance.

[0072] In addition, a dehumidification module can be installed in the box of the air drying device. When the hot air blows and dries the mat in the three-dimensional support frame, since the air drying process easily generates fog and makes the support frame relatively humid, the dehumidification module can remove the moisture in the support frame to prevent the moisture from affecting the subsequent air drying of the mat and reducing the air drying efficiency. A waterproof UV sterilization lamp is also installed inside the box 1 for sterilizing the mat.
