[0032] Example 1: Please refer to Figures 1-10As shown, the present invention provides a technical solution: a multifunctional hair dryer for forestry management, comprising a driving assembly 1, a flow guide assembly 2 is provided on the left side of the driving assembly 1, a linkage assembly 3 is provided on the right side of the driving assembly 1, a pumping assembly 4 is provided below the linkage assembly 3, a nozzle assembly 5 is provided outside the flow guide assembly 2, the driving assembly 1 comprises a first shell 101, a first sliding shell 102 is fixedly connected to the right surface of the first shell 101, a U-shaped frame 106 is fixedly connected to the top of the first shell 101, and a first ratchet 114 is rotatably connected to the right surface of the U-shaped frame 106, the flow guide assembly 2 comprises a connecting cylinder 201, and the connecting cylinder 201 is fixedly connected to the first shell 10 On the left surface, the linkage assembly 3 includes a second sliding shell 301. The second sliding shell 301 is slidably connected to the inner surface wall of the first sliding shell 102 near the right side. The rear inner surface wall of the second sliding shell 301 is fixedly connected to a connecting frame 302. A connecting sleeve 303 is rotatably connected to the inner surface wall of the connecting frame 302 near the left side. A sliding rod 310 is slidably connected to the inner surface wall of the connecting sleeve 303 near the left side. The left end of the sliding rod 310 is fixedly connected to a second ratchet 311, which cooperates with the first ratchet 114. A second spring 312 is fixedly connected between the right end of the sliding rod 310 and the right inner surface wall of the connecting sleeve 303.

[0033] The left inner surface wall of the U-shaped frame 106 is rotatably connected to the first bevel gear 107, the inner top of the U-shaped frame 106 is rotatably connected to the second bevel gear 108, and the right inner surface wall of the U-shaped frame 106 is rotatably connected to the third bevel gear 109. The first bevel gear 107 and the third bevel gear 109 are both meshed with the first bevel gear 107. A drive motor 110 is installed near the left side of the top of the first shell 101. The output end of the drive motor 110 rotates through the outer surface of the first shell 101 and the U-shaped frame 106 and is fixedly connected to the top of the second bevel gear 108. The left surface of the first bevel gear 107 is rotatably connected to a coupling extending to the left. 111. The left end of the coupling 111 is fixedly connected with the fan blade 112, and the third bevel gear 109 is fixedly connected to the first ratchet 114 through the shaft. When in use, the blowing nozzle 204 is directed to the fallen leaves position, and the driving motor 110 is started to drive the second bevel gear 108 to rotate, which will synchronously drive the first bevel gear 107 and the second bevel gear 108 to rotate. When the first bevel gear 107 rotates, it will drive the fan blade 112 inside the connecting tube 201 to rotate through the coupling 111, thereby drawing external air in from the air inlet 202 and then sending it out through the blowing tube 203 and the blowing nozzle 204, thereby blowing the fallen leaves and debris into a pile for easy cleaning.

[0034] A handle 104 is fixedly connected to the top of the first shell 101 near the right side, and a control knob 105 is installed on the outer surface of the handle 104. An I-shaped groove 103 is provided at the top of the first sliding shell 102 near the right side. The left end of the connecting tube 201 is fixedly connected to the hair dryer 203, and a hair dryer nozzle 204 is inserted at the left end of the hair dryer 203. An air inlet 202 is provided on the outer surface of the connecting tube 201. A heating wire 113 is installed on the left surface of the first shell 101 at the inner side of the connecting tube 201. When in use, the device can be easily taken and used by holding the handle 104 with the right hand and holding the hair dryer 203 with the left hand. The air inlet 202 is mainly used to connect the inside and outside of the connecting tube 201, so that the outside air Air can enter the connecting tube 201 and the hair dryer 203. At the same time, when it snows in winter and fallen leaves and debris are covered with snow, the heating wire 113 is started by turning the control knob 105. The heating wire 113 converts electrical energy into thermal energy, so that the air entering the air inlet 202 is heated into hot air before being sent out, which can melt the snow covering the fallen leaves and debris, thereby facilitating the cleaning of fallen leaves and debris in winter. The control knob 105 is mainly used to open and close the drive motor 110 and the heating wire 113 and adjust the working status of the drive motor 110 and the heating wire 113. The drive motor 110 and the heating wire 113 are powered by a power supply installed inside the device, and can also be powered by an external power supply line.

[0035] The pumping assembly 4 includes a pumping shell 401, which is fixedly connected to the bottom of the second sliding shell 301. The right end of the connecting sleeve 303 is fixedly connected to the crank 304. A piston 402 is slidingly provided between the inner surface walls of the pumping shell 401. The top of the piston 402 is fixedly connected to a connecting rod 403. The outer surface of the connecting rod 403 slides through the outer surface of the pumping shell 401 and the second sliding shell 301 and extends upward. The top end of the connecting rod 403 is rotatably connected to a rocker 404. The top end of the rocker 404 is rotatably connected to the journal of the crank 304. When in use, the first ratchet 114 follows the rotation of the third bevel gear 109 due to the simultaneous rotation of the second The ratchet 311 is in a one-way meshing state, so the second ratchet 311, the sliding rod 310 and the connecting sleeve 303 can rotate with the third bevel gear 109 without an additional power source. When the connecting sleeve 303 rotates, it will drive the crank 304 on the right to rotate synchronously. When the crank 304 rotates, the journal of the crank 304 will drive the upper end of the rocker arm 404 to perform eccentric movement. When the upper end of the rocker arm 404 moves to a high position, it will pull the connecting rod 403 to move upward. When the upper end of the rocker arm 404 moves to a low position, it will pull the connecting rod 403 to move downward. During this process, the connecting rod 403 will pull the piston 402 inside the pumping shell 401 to reciprocate up and down.

[0036] The outer surface of the water pumping shell 401 is fixedly connected to a first one-way valve 405 near the top on the right side, the outer surface of the water pumping shell 401 is fixedly connected to a third one-way valve 407 near the top on the left side, the outer surface of the water pumping shell 401 is fixedly connected to a second one-way valve 406 near the bottom on the right side, and the outer surface of the water pumping shell 401 is fixedly connected to a fourth one-way valve 408 near the bottom on the left side. A second three-way pipe 410 is fixedly connected between the input ends of the first one-way valve 405 and the second one-way valve 406, and the input end of the second three-way pipe 410 is fixedly connected to a water pumping pipe 411. A spherical filter screen 412 is installed at the bottom end of the water pumping pipe 411. When in use, since the first one-way valve 405 and the second one-way valve 406 only allow fluid to flow into the water pumping shell 401, the third one-way valve 407 and the fourth one-way valve 408 only allow fluid to flow out from the inside of the water pumping shell 401, the piston 402 is fixedly connected to the outer surface of the water pumping shell 401. When the piston 402 moves upward, the space below the pumping shell 401 increases, the pressure decreases and suction is generated, and the pesticide in the pesticide container can be pumped into the interior of the pumping shell 401 through the second one-way valve 406, the second three-way pipe 410 and the pumping pipe 411. When the piston 402 moves downward, the space below the pumping shell 401 decreases, and the pesticide inside will be squeezed out from the fourth one-way valve 408 and the first three-way pipe 409, while the space above the pumping shell 401 increases at the same time. The suction generated will pump the pesticide into the space above the pumping shell 401 through the first one-way valve 405, the second three-way pipe 410 and the pumping pipe 411. As the piston 402 moves up and down, the pesticide can be continuously extracted and sent out from the third one-way valve 407 and the fourth one-way valve 408. The spherical filter 412 is a hollow sphere as a whole, and a large number of filter holes are provided on the surface, which can prevent the pumping pipe 411 from being blocked due to the extraction of large particles of impurities when extracting pesticides.

[0037] A first three-way pipe 409 is fixedly connected between the output ends of the third one-way valve 407 and the fourth one-way valve 408. The first connecting pipe 205 is fixedly connected to the outer surface of the connecting tube 201 and the hair dryer 203 near the bottom through a clamp. The right end of the first connecting pipe 205 is fixedly connected to the output end of the first three-way pipe 409. The pesticides sent out from the third one-way valve 407 and the fourth one-way valve 408 will converge in the first three-way pipe 409 and be sent into the interior of the first connecting pipe 205 below the hair dryer 203.

[0038] The nozzle assembly 5 includes a connecting seat 501, the bottom of the connecting seat 501 is rotatably connected to a rotating shell 502, the interior of the rotating shell 502 is arranged as a cavity, the left surface of the rotating shell 502 is fixedly connected to an annular shell 505 extending upward, the inner surface wall of the annular shell 505 is equidistantly fixedly connected to a plurality of nozzles 506 tilted to the left, the front surface of the rotating shell 502 is fixedly connected to a second connecting pipe 504, the right end of the second connecting pipe 504 is fixedly connected to the left end of the first connecting pipe 205, when in use, As the pesticide is continuously pumped, the hydraulic pressure inside the first connecting pipe 205 is relatively high, and the pesticide will enter the annular shell 505 through the second connecting pipe 504 and the rotating shell 502, and finally be sprayed out from the nozzle 506. The airflow blown out by the blower 203 increases the pesticide spraying distance, thereby achieving the effect of spraying pesticides. The nozzle 506, the annular shell 505 and the rotating shell 502 are connected, and the pesticide will eventually be sprayed out from the nozzle 506, which plays a role in limiting the pesticide spraying path.

[0039] The steps of using the present invention are as follows: when using the device to blow away fallen leaves and debris in the forest garden during forest management, hold the handle 104 with the right hand, hold the blower tube 203 with the left hand, and point the blower nozzle 204 toward the fallen leaf position, then turn the drive motor 110 adjustment switch in the control knob 105. After the drive motor 110 is started, it drives the second bevel gear 108 to rotate, which will synchronously drive the first bevel gear 107 and the second bevel gear 108 to rotate. When the first bevel gear 107 rotates, it drives the fan blades 112 inside the connecting tube 201 to rotate through the coupling 111, thereby drawing in external air from the air inlet 202 and then sending it out through the blower tube 203 and the blower nozzle 204, thereby blowing the fallen leaves and debris into a pile for easy cleaning. When it snows in winter, the fallen leaves and debris When covered with snow, the heating wire 113 is activated by turning the control knob 105. The heating wire 113 converts electrical energy into thermal energy, so that the air entering the air inlet 202 is heated into hot air before being sent out, which can melt the snow covering the fallen leaves and debris, thereby facilitating the cleaning of fallen leaves and debris in winter. When it is necessary to spray pesticides on trees in forestry management, the pesticides are first prepared and added to a bucket or a backpack pesticide box, and then the spherical filter 412 at the bottom of the water pump 411 is put into the pesticide container, and then the second sliding shell 301 in the linkage assembly 3 is squeezed to slide toward the first sliding shell 102. At this time, the connecting frame 302 inside the second sliding shell 301 will drive the connecting sleeve 303 toward the first shell 101. When the second gear 303 is close to the first gear 303, the second spring 312 inside the connecting sleeve 303 will squeeze the sliding rod 310 inside the connecting sleeve 303, thereby pushing the second ratchet tooth 311 to fit with the first ratchet tooth 114 inside the first housing 101 and meshing them. When the first ratchet tooth 114 rotates with the third bevel gear 109, since the second ratchet tooth 311 is in a one-way meshing state at the same time, the second ratchet tooth 311, the sliding rod 310 and the connecting sleeve 303 can rotate with the third bevel gear 109 without an additional power source. When the connecting sleeve 303 rotates, it will drive the crank 304 on the right to rotate synchronously. When the crank 304 rotates, the journal of the crank 304 will drive the upper end of the rocker arm 404 to perform eccentric movement. When the upper end of the rocker arm 404 moves to a high position, it will pull the connecting rod 4 03 moves upward, and when the upper end of the swing rod 404 moves to the lower position, it will pull the connecting rod 403 downward. During this process, the connecting rod 403 will pull the piston 402 inside the water pumping shell 401 to reciprocate up and down. Since the first one-way valve 405 and the second one-way valve 406 only allow the fluid to flow into the water pumping shell 401, and the third one-way valve 407 and the fourth one-way valve 408 only allow the fluid to flow out from the inside of the water pumping shell 401, when the piston 402 moves upward, the space below the water pumping shell 401 increases, the pressure decreases and suction is generated, and the pesticide in the pesticide container can be pumped into the water pumping shell 401 through the second one-way valve 406, the second three-way pipe 410 and the water pumping pipe 411. When the piston 402 moves downward, the space below the water pumping shell 401 shrinks.The pesticide inside will be squeezed out from the fourth one-way valve 408 and the first three-way pipe 409, and the space above the pumping shell 401 will increase at the same time. The suction force generated will draw the pesticide into the space above the pumping shell 401 through the first one-way valve 405, the second three-way pipe 410 and the pumping pipe 411. As the piston 402 moves up and down, the pesticide can be continuously drawn out and sent into the first connecting pipe 205 below the hair dryer 203 through the first three-way pipe 409. As the pesticide is continuously pumped, the hydraulic pressure inside the first connecting pipe 205 is relatively large. The pesticide enters the annular housing 505 through the second connecting tube 504 and the rotating housing 502, and is finally sprayed out of the nozzle 506. The airflow from the blower 203 increases the spraying distance of the pesticide, achieving the desired spraying effect. Without adding an additional delivery pump, this device only adds the low-cost and lightweight linkage assembly 3, the pumping assembly 4, the nozzle assembly 5, and the heating wire 113. In addition to the blowing operation, it also has the effects of heating, blowing, snow melting, and spraying pesticides, meeting the diverse needs of forestry management.

[0040] Example 2: Figures 1-8 As shown, the difference between the embodiment and the embodiment is that two clips 503 are fixedly connected to the bottom of the connecting seat 501 near the rear side, and the clips 503 cooperate with the rotating shell 502. When in use, the clip 503 on the right side of the bottom of the connecting seat 501 is pressed to disengage it from the rotating shell 502, and then the annular shell 505 is rotated to the left to rotate it to an upward vertical state. At this time, the rotating shell 502 will be engaged with the clip 503 on the left side of the bottom of the connecting seat 501. Conversely, when the annular shell 505 is reset, the fixation of the left clip 503 and the rotating shell 502 is released so that the right clip 503 is engaged with the rotating shell 502, and the annular shell 505 in the downward rotated state can be fixed.

[0041] The use steps of the present invention are as follows: when the device is used for daily blowing function, different styles of blowing nozzles 204 can be replaced according to actual usage conditions, thereby improving the blowing effect. When pesticide spraying is required, the blowing nozzle 204 is removed and the linkage assembly 3 is pushed forward to engage the first ratchet 114 and the second ratchet 311. Then, the buckle 503 on the right side below the connecting seat 501 is pressed to disengage it from the rotating shell 502. Then, the annular shell 505 is rotated to the left to rotate it to an upward vertical state. At this time, the annular shell 505 and The hair dryer 203 is in a concentric state, and the airflow blown out by the hair dryer 203 can increase the pesticide spraying distance, and the rotating shell 502 that rotates with the annular shell 505 will be clamped and fixed by the buckle 503 on the left side below the connecting seat 501, ensuring the stability of the device when spraying pesticides. Conversely, after releasing the left buckle 503, the right buckle 503 is clamped and connected with the rotating shell 502, which can avoid the annular shell 505 from shaking during the blowing process. The structure is simple, and the stability and practicality of the device when in use are effectively improved.

[0042] Example 3: Figures 1-4 and Figure 6 As shown, the difference between the embodiment and the basis is that the inner top of the second sliding shell 301 is fixedly connected to the sliding sleeve 305, the inner surface wall of the sliding sleeve 305 is slidably connected with a sliding plate 306, the bottom of the sliding plate 306 and the inner bottom of the sliding sleeve 305 are fixedly connected with a first spring 309, the top of the sliding plate 306 is fixedly connected to the limiting block 307, the top of the limiting block 307 is fixedly connected to the pressure rod 308, the I-shaped groove 103 consists of two transverse grooves and one longitudinal groove, the longitudinal grooves on the outer surface of the pressure rod 308 match, the limiting block 307 and the transverse groove match, when in use, press the pressure rod 308, at this time the limiting block 307 at the bottom of the pressure rod 308 The block 307 and the sliding plate 306 will retract into the interior of the sliding sleeve 305. During this process, the first spring 309 will be compressed and contracted. When the limit block 307 is disengaged downward from the right side of the I-slot 103 on the surface of the first sliding shell 102, the second sliding shell 301 can be easily pushed to the left. When the second sliding shell 301 slides to the far left, the pressure rod 308 is released. At this time, the first spring 309 rebounds and pushes the sliding plate 306 to move to the top of the sliding sleeve 305, and the limit block 307 on the top of the sliding plate 306 will synchronously move up and enter the leftmost horizontal groove of the I-slot 103, thereby fixing the first sliding shell 102 and the second sliding shell 301.

[0043] The steps of using the present invention are as follows: when it is necessary to push the second sliding shell 301 toward the first sliding shell 102 and adjust the device to the pesticide spraying state, the pressure rod 308 can be pressed first. At this time, the limit block 307 and the sliding plate 306 at the bottom of the pressure rod 308 will be retracted into the interior of the sliding sleeve 305. During the process, the first spring 309 will be compressed and contracted. When the limit block 307 is disengaged downward from the right side of the I-groove 103 on the surface of the first sliding shell 102, the second sliding shell 301 can be easily pushed to the left. Moreover, since the round rod part below the pressure rod 308 is always located inside the I-groove 103, it plays a role in spraying pesticides. The function of limiting the sliding stroke of the second sliding shell 301 is to release the pressure rod 308 when the second sliding shell 301 slides to the extreme left. At this time, the first spring 309 rebounds and pushes the sliding plate 306 to move to the uppermost part of the sliding sleeve 305, and the limit block 307 on the top of the sliding plate 306 will move up synchronously and enter the leftmost horizontal groove of the I-shaped groove 103, thereby fixing the first sliding shell 102 and the second sliding shell 301. The design structure is simple, and the device can be easily adjusted to the pesticide spraying state or the single blowing state. It is easy to operate and has high practicality.
