The automatic retractable hose reel can be used in irrigation systems; in car repair and beauty shops, it can be used to manage car washing equipment, air guns, power cords, etc. For example, the prior art publication number CN215905627U discloses a patent entitled an automatic hose reel, which includes a storage cylinder with a pipeline wound on it, a wheel disc provided on one side of the storage cylinder, a driving disc transmission-connected to the wheel disc, a plurality of driving magnets evenly provided along the circumferential direction of the driving disc, the driving magnet is tilted on the driving disc, and a driving handle is rotatably provided, the driving handle is provided with a main magnet of the same polarity as the driving magnet that repels each other, and the driving handle can be rotated to make the main magnet face or separate from the driving magnet.

[0003] The disadvantages of the hose reels in the prior art are that when used in larger places, since the installation angle of the hose reels is relatively fixed, the operator can easily pull out the pipe when he is below the lead-out end of the hose reel and pulls the pipe. However, when the operator stands at a more biased angle, the side wall of the pipe is squeezed against the parts of the hose reel, which increases the friction. At this time, the pulling force needs to be increased, and the pipe is easily worn during the pulling process. Summary of the invention

[0023] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

The housing 101 is fixed to the mounting frame 104 via a connector 105. One end of the mounting frame 104 is fixedly mounted on a wall 106. A driving column 308, both ends of which are rotatably connected to the inner walls of the housing 101 and the rear cover 102, and one end of which is connected to a first motor 311, which drives the driving column 308 to rotate, thereby achieving the effect of winding and unwinding the pipe 2; A winding disc 309 is fixedly connected to the middle of the driving column 308. The middle of the winding disc 309 has a receiving groove. The width of the receiving groove is greater than the diameter of the pipe 2. The pipe 2 is wound in the receiving groove in the middle of the winding disc 309. The tensioning wheel 303 is rotatably mounted on the inner wall of the rear cover 102. Figure 3 As shown, the pipe 2 is U-shaped and surrounds the outer wall of the tension wheel 303, and the tension wheel 303 has resistance when rotating; A rotating seat 301 is fixedly connected to the inner wall of the rear cover 102, a rotating column 302 is rotatably connected to the middle of the rotating seat 301, and the other end of the rotating column 302 is fixedly connected to the middle of the tensioning wheel 303; A sliding sleeve 304, fixedly connected to the inner wall of the rear cover 102; A sliding column 305, the top of which is slidably connected to the inner wall of the sliding sleeve 304, and a squeezing block 306 is fixedly connected to the bottom of the sliding column 305, the shape of the bottom of the squeezing block 306 matches the shape of the outer wall of the rotating column 302, and a first spring 307 is connected between the top of the sliding column 305 and the top of the inner wall of the sliding sleeve 304, and the first spring 307 squeezes the sliding column 305 and the squeezing block 306 toward the outer wall of the rotating column 302, thereby increasing the resistance of the rotating column 302 when rotating. It should be noted that those skilled in the art can select the model of the first spring 307 according to the diameter and toughness of the pipe 2, so as to generate different downward pressures, and then adjust the resistance of the rotating column 302 when rotating; In the above scheme, since the pipe 2 generates friction with the outer wall of the tensioning wheel 303 when passing through the tensioning wheel 303, and since the rotation process of the rotating column 302 has resistance, when the first motor 311 drives the driving column 308 to reel in the pipe 2, under the influence of the rotation resistance of the tensioning wheel 303, a dragging effect can be generated on the reeled portion of the pipe 2, thereby tightening the reeled portion of the pipe 2, thereby making the reeled pipe 2 more stable.

[0025] As a possible embodiment, Figure 4 As shown, this embodiment also includes: A first driven gear 310, fixedly connected to the rear end of the winding disc 309; The first driving gear 312 is fixedly connected to the output end of the first motor 311. Through the above scheme, when the first motor 311 is started, it can drive the first driving gear 312 to rotate. Since the first driving gear 312 is meshed with the first driven gear 310, the first driven gear 310 rotates synchronously, and then drives the winding disk 309 to rotate. By controlling the forward and reverse rotation of the first motor 311, the winding and unwinding effect of the pipeline 2 is achieved.

[0026] As a possible embodiment, Figure 5 As shown, a feed chamber 313 is provided inside the driving column 308, and one end of the feed chamber 313 penetrates one end of the driving column 308, so that external gas or liquid can be connected to one end of the feed chamber 313, thereby realizing feeding, and an installation port 314 is provided on the inner wall of the feed chamber 313, and one end of the pipeline 2 is fixedly connected to the installation port 314, so that the material in the feed chamber 313 can enter the pipeline 2 from the installation port 314.

The limiting ball 201 is penetrated from top to bottom with an extrusion seam 204, and the extrusion seam 204 is penetrated horizontally with a through hole 203; The bolt 205 and the nut 206 are formed by passing the bolt 205 through the through hole 203 and then installing the nut 206 on the bolt 205 . The bolt 205 and the nut 206 are rotated to squeeze the extrusion gap 204 , thereby firmly fixing the limiting ball 201 on the outer wall of the pipe 2 .

[0028] As a possible embodiment, Figure 7 , Figure 8 As shown, this embodiment also includes: A smoothing wheel 315 is installed inside the housing 101. The smoothing wheel 315 is located entirely below the wound pipe 2. The lower portion of the pipe 2 contacts the top of the smoothing wheel 315. A fixing frame 316, fixedly connected to the bottom of the inner wall of the housing 101, and two ends of the fixing frame 316 are provided with sliding grooves 317; There are two sliders 318, and the two sliders 318 are respectively mounted on the shafts at both ends of the smoothing wheel 315. The shafts at both ends of the smoothing wheel 315 can rotate relative to the sliders 318. The sliders 318 are rectangular and are slidably installed in the slide groove 317. An electromagnetic spring 319 is connected between the top of the slider 318 and the top of the inner wall of the slide groove 317. When the electromagnetic spring 319 is energized, it can shrink, thereby driving the two sliders 318 to slide upward, and then allowing the entire smoothing wheel 315 to slide upward, thereby squeezing the pipe 2 in the winding process upward, so that the pipe 2 is not easy to loosen during winding, thereby achieving a smoothing effect.

[0029] As a possible embodiment, Fig. 9 , Fig.10, Fig.11 As shown, this embodiment also includes: A driving wheel 320 is installed on one side of the inlet and outlet 103, and one side of the driving wheel 320 is closely attached to one side of the pipe 2; There are two squeezing wheels 321, which are closely attached to the other side of the pipe 2, and a triangle structure is formed between the two squeezing wheels 321 and the driving wheel 320, so as to fully clamp the pipe 2; A movable frame 322 is hingedly mounted on the inner wall of the rear cover 102, and the driving wheel 320 is rotatably mounted on the end of the movable frame 322; A fixed column 323, one end of the movable frame 322 is hinged to the fixed column 323 through a torsion spring 324, and the movable frame 322 and the driving wheel 320 are always pressed toward the direction of the pipe 2 through the action of the torsion spring 324, thereby increasing the friction between the driving wheel 320 and the outer wall of the pipe 2; The annular groove 325 is provided in the middle of the driving wheel 320, and the inner wall of the annular groove 325 is in full contact with the outer wall of the pipe 2, thereby further increasing the friction force and improving the transmission efficiency; A driving rod 326 is rotatably mounted on the middle of the movable frame 322, and two ends of the driving rod 326 are rotatably connected to the rotating sleeves 330 at two ends of the movable frame 322; A second motor 327 is fixedly mounted on one end of the movable frame 322, and an output end of the second motor 327 is connected to one end of the driving rod 326; A second driving gear 328 connected to the outer wall of the driving rod 326; A second driven gear 329 connected to the outer wall of the driving wheel 320 , wherein the second driven gear 329 is meshed with the second driving gear 328 ; Through the above scheme, the second motor 327 drives the driving rod 326 and the second driving gear 328 to rotate, so that the second driving gear 328 drives the second driven gear 329 and the driving wheel 320 to rotate. Since the inner wall of the annular groove 325 in the middle of the driving wheel 320 is fully squeezed and contacted with the outer wall of the pipe 2, and the two squeezing wheels 321 and the driving wheel 320 jointly squeeze the pipe 2, and cooperate with the rotation of the winding disk 309, the driving wheel 320 can drive the pipe 2 to move up and down when rotating, thereby achieving the effect of winding and unwinding.

[0030] It should be noted that when the pipe 2 is wound up, the speed at which the pipe 2 is driven by the winding disc 309 is greater than the speed at which the pipe 2 is driven by the driving wheel 320. When the pipe 2 is released, the speed at which the pipe 2 is driven by the driving wheel 320 is greater than the speed at which the pipe 2 is driven by the winding disc 309, so that the pipe 2 wound up on the winding disc 309 can be tightened. Both of the above working modes can be realized by a controller, which can realize the control of the first motor 311 and the second motor 327. The principles of wireless control include: Transmitter: The wireless controller is usually equipped with a radio frequency transmitting antenna, which is used to send out wireless signals containing digital commands. These commands are usually entered by the user through a PC, mobile phone or other device and converted into wireless signals for transmission.

[0031] Receiver: The RF antenna installed near the motor is responsible for receiving these wireless signals. Once the signal is received, the receiver converts it into an electrical signal and further decodes it to get the original command.

[0032] As a possible embodiment, Fig.12 As shown, this embodiment also includes: A rotating frame 401, a rotating ring 403 is fixedly connected to the top thereof, and the rotating ring 403 is rotatably connected to the inner wall of the inlet and outlet 103 through a bearing; A guide wheel 402, wherein the guide wheel 402 has a plurality of guide wheels 402, and the plurality of guide wheels 402 are arranged in an arc shape and rotatably mounted on the rotating frame 401, and the lower part of the pipeline 2 is led out in an arc shape through the plurality of guide wheels 402; During the use of the pipe 2, since the angle of use needs to be changed, the operator needs to hold the head of the pipe 2 and move it around. Therefore, friction is prone to occur at the position where the pipe 2 contacts the inlet and outlet 103, causing wear of the pipe 2. Therefore, through the above scheme, the lead-out angle of the pipe 2 is changed to an arc shape through a plurality of guide wheels 402, and when the operator holds the head of the pipe 2 and moves it around, the rotating frame 401 and the rotating ring 403 follow the rotation, so that the pipe 2 is always maintained at a fixed position and angle, and no friction occurs, thereby increasing the service life of the pipe 2, and by providing the guide wheel 402, the pipe 2 led out from the lower part can be in a horizontal state, so that it can be used in large places, and through automatic unwinding, there is no need to pull the pipe 2.

Press the unwinding button, and the first motor 311 rotates counterclockwise, and the second motor 327 rotates clockwise to release the pipe 2. The moving speed of the pipe 2 driven by the second motor 327 and the driving wheel 320 is greater than the moving speed of the pipe 2 driven by the first motor 311 and the winding disk 309. S2, press the reel button, at this time the first motor 311 rotates clockwise, the second motor 327 rotates counterclockwise, the pipe 2 is wound on the winding disk 309, and the moving speed of the pipe 2 driven by the first motor 311 and the winding disk 309 is greater than the moving speed of the pipe 2 driven by the second motor 327 and the driving wheel 320; S3.
