Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, and specifically relates to an umbrella folder. Background Technology

[0002] An umbrella is a common tool in daily life, used to protect users from rain and sun. After using an umbrella, it usually needs to be folded and closed. Generally, this is done manually, involving: drying the umbrella by air-drying or shaking it, then folding the canopy clockwise or counterclockwise and securing it with a strap. Manual folding is time-consuming and laborious. Please refer to utility model patent CN201821264063.8, entitled "An Automatic Umbrella Folder," which discloses an automatic umbrella folder. However, this folder typically only shakes or dries the umbrella, and cannot fold it properly. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide an umbrella folder that can automatically fold up an umbrella, and is simple and convenient to operate.

[0004] The embodiments of the present invention are implemented as follows:

[0005] This invention provides an umbrella closer, including an outer cylinder, an inner cylinder, a clamping mechanism, and an umbrella canopy closing mechanism. The inner cylinder is rotatably disposed inside the outer cylinder, and a drainage plate with a drainage hole is provided at the bottom of the inner cylinder. The clamping mechanism is disposed at the top of the inner cylinder and is used to clamp the umbrella. The umbrella canopy closing mechanism extends movably into the inner cylinder and is capable of retracting inward or opening outward and is configured to organize and close the umbrella canopy.

[0006] As an optional embodiment of the above, the umbrella closeer includes a rotating base and two clamping mechanisms. The rotating base is rotatably disposed on the top of the inner cylinder, and the rotation center line of the rotating base coincides with the center line of the inner cylinder. Each clamping mechanism includes a servo motor, a transmission assembly, and several clamping blades. The servo motor is disposed on the rotating base, and the several clamping blades are evenly distributed on the rotating base and form a closed clamping area. The clamping blades are rotatably connected to the rotating base to change the size of the clamping area. The servo motor drives the clamping blades to rotate through the transmission assembly. The two clamping mechanisms... The mechanism includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is used to clamp the umbrella handle, and the second clamping mechanism is used to clamp the ends of the umbrella ribs. The clamping mechanism has a clamping state and a retracted state: when the clamping mechanism is in the clamping state, the umbrella is placed into the inner tube, and the first clamping mechanism retracts before the second clamping mechanism and clamps and fixes the umbrella handle; when the clamping mechanism is in the retracted state, the umbrella surface gathering mechanism tidies up the umbrella surface, and the second clamping mechanism gradually retracts to gather the ends of the umbrella ribs towards the middle.

[0007] As an optional embodiment of the above, the transmission assembly includes an internal gear ring, a drive gear, and a plurality of driven gears. The internal gear ring is rotatably mounted on the rotating base, and the rotation center line of the internal gear ring coincides with the center line of the rotating base. The drive gear is connected to the output end of the servo motor. Each driven gear corresponds to a clamping leaf and is rotatably mounted on the rotating base. One end of each clamping leaf is connected to a driven gear. The drive gear and the driven gear mesh with the internal gear ring respectively. The servo motor rotates through the drive gear and drives the gear ring to rotate, so that the driven gear drives the clamping leaf to rotate.

[0008] As an optional embodiment of the above, the umbrella canopy gathering mechanism includes a gathering motor, a gathering screw, a gathering nut, and several rubber rollers; the gathering motor is located at the bottom of the outer cylinder, the gathering screw is vertically arranged and coaxially connected to the output end of the gathering motor, the gathering screw is located below the inner cylinder, and the gathering nut is movably sleeved on the gathering screw, the gathering screw and the gathering nut forming a screw-nut mechanism; the bottom of the inner cylinder is provided with a through hole with a slope, the slope gradually narrowing inward from top to bottom, the bottom of the rubber roller is hinged to the gathering screw, a return spring is provided between the rubber roller and the gathering nut, the return spring causing the rubber roller to have a tendency to swing outward; the rubber roller passes through the through hole and extends into the inner cylinder, the rubber roller... The umbrella condenser is equipped with several gathering rollers, and each roller has a sloped surface that matches the ramp. When the gathering nut lowers the roller, the roller swings inward under the combined action of the ramp and the sloped surface, bringing the gathering roller closer to the umbrella surface. When the gathering nut raises the roller, the roller swings outward under the action of the return spring, moving the gathering roller away from the umbrella surface. The umbrella condenser has a first state and a second state: when the umbrella condenser is in the first state, the inner cylinder, the gathering screw, the gathering nut, and the roller can rotate synchronously. When the umbrella condenser is in the second state, the inner cylinder and the outer cylinder are locked, the gathering screw can drive the gathering nut and the roller to rise and fall, and the clamping mechanism can rotate in the same direction as the gathering screw.

[0009] As an optional embodiment of the above, the umbrella closer further includes a conversion mechanism, which includes a locking ring, a swing arm, a conversion spring, and a lifting member. The locking ring is coaxially disposed inside the outer cylinder and near the bottom end of the inner cylinder, and the bottom side of the locking ring is provided with a plurality of locking teeth. The swing arm is disposed radially along the inner cylinder and its middle portion is swayably disposed at the bottom end of the inner cylinder. The outer end of the swing arm is provided with a locking head that engages with the locking teeth. The conversion spring is connected to the inner cylinder and the swing arm respectively and tends to press the locking head against the locking ring. The lifting member is fixedly disposed on the top of the retracting screw. It can extend and retract vertically. The bottom of the inner cylinder is provided with a transmission hole that matches the extension end of the lifting component. When the lifting component rises, it can drive the swing arm to swing, so that the locking head disengages from the locking tooth, and the lifting component is inserted into the transmission hole, so that the inner cylinder, the tightening screw, the tightening nut, and the rubber roller can rotate synchronously. When the lifting component descends, the swing arm is reset under the action of the conversion spring, the locking head locks with the locking tooth, the inner cylinder is fixed to the outer cylinder, and the lifting component disengages from the transmission hole. The tightening screw can drive the tightening nut and the rubber roller to rise and fall.

[0010] As an optional embodiment of the above, the inner cylinder includes a cylinder body and a turntable. The turntable is rotatably disposed on the inner bottom of the cylinder body and is used to support the umbrella tip. The turntable is provided with a clamping member for holding the umbrella tip. The turntable is drivenly connected to the gathering screw, and the rotating seat is driven to the turntable via the umbrella. Alternatively, the turntable is not connected to the gathering screw, and the rotating seat is driven to rotate by a tidying motor. The axis of the gathering wheel is inclined and out of plane relative to the center line of the inner cylinder. When the umbrella folder is in the second state, the gathering wheel rolls in a spiral direction on the umbrella surface.

[0011] As an optional embodiment of the above, the umbrella folder further includes an umbrella surface straightening assembly, which includes a blower, an air pipe, and several suction nozzles. The blower is disposed inside the inner cylinder, and the suction nozzles are evenly distributed along the circumference of the inner cylinder on the inner surface of the inner cylinder. In the same cross-section, the orientation of the suction nozzles is inclined relative to the radial direction of the inner cylinder, and the inclination directions of the several suction nozzles are rotationally symmetrical. The blower and the suction nozzles are connected through the air pipe. When the clamping assembly is in the closed state, the blower operates, and the suction nozzles are able to draw air and attract the umbrella surface to bring out the umbrella surface between any two adjacent umbrella ribs, while the second clamping mechanism gradually retracts.

[0012] As an optional embodiment of the above, the umbrella closer further includes a ring ejection mechanism, which is disposed at the top of the inner cylinder and is used to hold and release the rubber ring to tighten the umbrella canopy.

[0013] As an optional embodiment of the above, the ring ejection mechanism includes a pre-placement component and an ejection component. The pre-placement component includes several inclined members, which are inclinedly disposed inside the inner cylinder. Each inclined member is provided with a sliding groove that slopes inward from top to bottom. The bottom end of the sliding groove is open. The sliding grooves of several inclined members are used together to place the rings. The ejection component is disposed below the inclined members and is used to allow the rings to disengage one by one from the sliding groove and tighten onto the umbrella surface.

[0014] As an optional embodiment of the above, the pop-out component corresponds one-to-one with the tilting component. Each pop-out component includes a bracket, a swinging component, and a control component. The bracket is disposed in the inner cylinder, the swinging component is oscillatingly disposed in the bracket, and the control component is used to control the swinging component to swing. When the swinging component swings, it can open or close the opening of the tilting component.

[0015] As an optional embodiment of the above, the umbrella folder further includes a plurality of support legs, which are distributed along the circumference of the outer cylinder at the bottom of the outer side of the outer cylinder and are used to support the outer cylinder.

[0016] As an optional embodiment of the above, the umbrella closer further includes several alarm components. Each alarm component includes a column, a vacuum suction cup, an alarm, a trigger, and a return spring. The column is fixed to the bottom of the support legs and has a vertical cylindrical cavity. The vacuum suction cup is located at the bottom of the column and has a conical vacuum cavity. The alarm is located on the column and has a control switch and a trigger switch. The control switch is configured for manual control. When both the control switch and the trigger switch are turned on simultaneously, the alarm will sound. When either the control switch or the trigger switch is closed, the alarm cannot sound; the trigger switch is located inside the cylindrical cavity, and the trigger element is vertically and vertically inserted into the cylindrical cavity with a sealed contact between the two, with the bottom end of the trigger element extending into the conical vacuum cavity; when the vacuum suction cup deforms and adheres to the ground, the conical vacuum cavity deforms and the bottom end of the column moves downward, the trigger element rises relative to the column, and the trigger switch is closed; when the vacuum suction cup resets, the conical vacuum cavity returns to its original shape and the bottom end of the column moves upward, triggering the trigger element.

[0017] The beneficial effects of this invention are:

[0018] The umbrella folder provided by this invention has an outer cylinder for supporting other components, an inner cylinder that can rotate relative to the outer cylinder to rotate the umbrella and shake off rainwater from the umbrella surface. Rainwater dripping from the umbrella surface flows out through drainage holes on a drainage plate. A clamping mechanism secures the umbrella for easy handling, and an umbrella folding mechanism folds and gathers the umbrella surface and ribs. This umbrella folder automatically folds the umbrella and is simple and convenient to operate. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0044] Please refer to Figure 1 , Figure 2 As shown, an embodiment of the present invention provides an umbrella folder 10, which is used to fold up umbrellas, and of course, can also fold up parasols, etc.

[0045] The umbrella folder 10 includes an outer cylinder 11, an inner cylinder 12, a clamping mechanism 13, and an umbrella surface gathering mechanism 15. The outer cylinder 11 is used to support other components, the inner cylinder 12 is used to hold the umbrella, the clamping mechanism 13 is used to clamp and fix the umbrella or gather the umbrella towards the center, and the umbrella surface gathering mechanism 15 is used to gather the umbrella surface towards the center.

[0046] The structure of the outer cylinder 11 is not limited. The outer cylinder 11 can be in the shape of a cylindrical tube 139, with the bottom closed and the top open. Several support legs 110 can be provided on the outside of the outer cylinder 11. The number and structure of the support legs 110 are not limited; the more support legs 110 there are, the more stable the outer cylinder 11 will be. In this embodiment, there are four support legs 110, distributed circumferentially along the bottom of the outer cylinder 11. The bottom ends of the support legs 110 are flush with the bottom end of the outer cylinder 11, used to support the outer cylinder 11 and prevent it from tipping over. Of course, in other embodiments, it is also possible not to provide support legs 110 on the outside of the outer cylinder 11.

[0047] The inner tube 12 is rotatably disposed within the outer tube 11. The inner tube 12 may also have a cylindrical structure with an opening at the top to allow the umbrella to be inserted. The rotatable connection between the inner tube 12 and the outer tube 11 is not limited. In this embodiment, the following solutions may be used, but are not limited to: [Please refer to...] Figure 3 As shown, an annular groove 111 is provided on the inner surface of the outer cylinder 11. The annular groove 111 is arranged along the circumference of the outer cylinder 11, and the cross-section of the annular groove 111 is not limited, for example, the cross-section is an arc shape. Several rollers 120 are provided on the outer surface of the inner cylinder 12. The rollers 120 are rotatably embedded in the annular groove 111. The rollers 120 can be omnidirectional wheels and match the shape of the annular groove 111. The inner cylinder 12 and the outer cylinder 11 can only rotate relative to each other, and cannot move up and down relative to each other. The rotation center line of the inner cylinder 12 coincides with the center line of the outer cylinder 11.

[0048] Please combine Figure 4 As shown, a drainage plate 121 is provided at the bottom of the inner cylinder 12. The shape of the upper surface of the drainage plate 121 is not limited. For example, the upper surface of the drainage plate 121 can be a concave cone to allow rainwater to converge in the center; or the upper surface of the drainage plate 121 can be a flat surface. A drainage hole is provided on the drainage plate 121, which can penetrate the bottom of the inner cylinder 12 to allow rainwater dripping from the umbrella to flow out through the drainage hole into the outer cylinder 11 for centralized collection and treatment. Alternatively, a water outlet is provided at the bottom of the outer cylinder 11 to drain the rainwater collected inside the outer cylinder 11. Furthermore, in some embodiments, a drying component can be provided on the inner surface of the inner cylinder 12 to dry the rainwater on the umbrella surface. In this case, the drainage plate 121 only plays an auxiliary role, i.e., rainwater dripping from the umbrella surface cannot be dried in time and falls onto the drainage plate 121.

[0049] A clamping mechanism 13 is located at the top of the inner cylinder 12 and is used to clamp the umbrella. The number of clamping mechanisms 13 is unlimited. If the umbrella folder 10 contains only one clamping mechanism 13, then the clamping mechanism 13 needs to clamp the umbrella handle. If the umbrella folder 10 contains two clamping mechanisms 13, then the two clamping mechanisms 13 are a first clamping mechanism 134 and a second clamping mechanism 135, wherein the first clamping mechanism 134 is used to clamp the umbrella handle, and the second clamping mechanism 135 is used to clamp the umbrella ribs. The clamping mechanism 13 clamps and fixes the umbrella handle to fix the umbrella as a whole and prevents the umbrella from shaking when storing and organizing it. The clamping mechanism 13 clamps and fixes the umbrella ribs to fold the umbrella canopy and ribs together.

[0050] The structure of the clamping mechanism 13 is not limited. In this embodiment, the following solutions can be adopted, but are not limited to: Please refer to Figure 5 , Figure 6 As shown, the umbrella folder 10 includes a rotating base 130 and two clamping mechanisms 13.

[0051] The rotating base 130 is rotatably mounted on the top of the inner cylinder 12. Alternatively, the rotating base 130 can directly rotate with the inner cylinder 12, or it can rotate with the outer cylinder 11, i.e., the rotating base 130 and the inner cylinder 12 can rotate indirectly. The rotation center line of the rotating base 130 coincides with the center line of the inner cylinder 12. In some embodiments, the rotating base 130 can be driven to rotate by a tidying motor (not shown in the figure), which is fixed to the inner cylinder 12. The output end of the tidying motor is connected to the rotating base 130 via gear transmission. In other embodiments, the rotating base 130 can also be driven to rotate in other ways. The rotating base 130 is generally annular, and its shape is not limited. The rotational engagement method between the rotating base 130 and the inner cylinder 12 is not limited. For example, the bottom end of the rotating base is connected to the top end of the inner cylinder 12 via a plane bearing, or a method similar to the rotational connection between the inner cylinder 12 and the outer cylinder 11 can be used. The structure of the rotating base 130 is not limited. For example, in this embodiment, the rotating base 130 includes a cylinder 139 and three layers of fixing plates 140. The three layers of fixing plates 140 are spaced apart inside the cylinder 139. The first clamping mechanism 134 is located between the upper two layers of fixing plates 140, and the second clamping mechanism 135 is located between the lower two layers of fixing plates 140.

[0052] Each clamping mechanism 13 includes a servo motor 131, a transmission assembly, and several clamping blades 133. The shape of the clamping blades 133 is not limited; they can be rod-shaped, strip-shaped, or strip-shaped, etc. Several clamping blades 133 are evenly distributed on the rotary base 130 and form a closed clamping area. The clamping blades 133 are rotatably connected to the rotary base 130. The coordinated rotation of the clamping blades 133 changes the size of the clamping area, allowing the clamping mechanism 13 to clamp or release the umbrella. The servo motor 131 is located on the rotary base 130 and drives the clamping blades 133 to rotate via the transmission assembly. The structure of the servo motor 131 can refer to existing technology, such as a small motor.

[0053] The structure of the transmission assembly is not limited, as long as it enables the servo motor 131 to drive the clamping blade 133 to rotate. The transmission method can refer to the prior art. In this embodiment, the following scheme can be adopted, but is not limited to: The transmission assembly includes an internal gear ring 136, a driving gear 137, and several driven gears 138. The internal gear ring 136 is rotatably disposed on the rotary seat 130. The rotational engagement method between the two is not limited. It can refer to the prior art, or it can adopt a rotational engagement method similar to that between the rotary seat 130 and the inner cylinder 12, or a limiting groove is provided on the inner side of the rotary seat 130, and the internal gear ring 136 is rotatably embedded in the limiting groove, with the rotation center line of the internal gear ring 136 coinciding with the center line of the rotary seat 130. The drive gear 137 is connected to the output end of the servo motor 131. The driven gear 138 corresponds one-to-one with the clamping leaf 133 and is rotatably mounted on the rotary seat 130. One end of the clamping leaf 133 is connected to the driven gear 138. The drive gear 137 and the driven gear 138 mesh with the internal gear ring 136 respectively. The servo motor 131 rotates through the drive gear 137, which in turn drives the gear ring to rotate, thereby causing the driven gear 138 to drive the clamping leaf 133 to rotate. In other embodiments, the internal gear ring 136 can be replaced with a chain, and the drive gear 137 and the driven gear 138 can be replaced with sprockets.

[0054] The clamping mechanism 13 has a clamping state and a folding state: When the clamping mechanism 13 is in the clamping state, the umbrella is placed into the inner tube 12, and the first clamping mechanism 134 retracts before the second clamping mechanism 135, clamping and fixing the umbrella handle. When the clamping mechanism 13 is in the folding state, the umbrella canopy gathering mechanism 15 tidies up the umbrella canopy, and the second clamping mechanism 135 gradually retracts to gather the ends of the umbrella ribs towards the center. Simply put, once the umbrella is placed into the inner tube 12, the umbrella handle is fixed. After the umbrella is fixed, the user can release the umbrella, and then the umbrella folder 10 folds the umbrella. During the folding process, since the umbrella canopy needs to be gathered and tidied up first, the second clamping mechanism 135 needs to gradually gather the umbrella ribs towards the center after or during the tidying process to facilitate subsequent operations.

[0055] The umbrella canopy tightening mechanism 15 extends movably into the inner tube 12. The umbrella canopy tightening mechanism 15 is capable of retracting inward or opening outward and is configured to straighten and tighten the umbrella canopy.

[0056] In this embodiment, the umbrella canopy gathering mechanism 15 can adopt, but is not limited to, the following solutions: Please refer to... Figure 7 , Figure 8 As shown, the umbrella canopy gathering mechanism 15 includes a gathering motor 150, a gathering screw 151, a gathering nut 152, and several rubber rollers 153.

[0057] The coiling motor 150 can be a motor from the prior art. The coiling motor 150 is located at the bottom of the outer cylinder 11. The coiling screw 151 is arranged vertically and is coaxially connected to the output end of the coiling motor 150. The coiling screw 151 is located below the inner cylinder 12. The coiling nut 152 is detachably sleeved on the coiling screw 151. The coiling screw and the coiling nut 152 constitute a screw-nut mechanism.

[0058] The bottom of the rubber roller 153 is hinged to the tightening screw 151. A return spring 156 is provided between the rubber roller 153 and the tightening nut 152. The return spring 156 causes the rubber roller 153 to have an outward swing tendency. The return spring 156 can be a torsion spring, compression spring, tension spring, etc. The two ends of the return spring 156 are connected to the rubber roller 153 and the tightening nut 152 respectively. The connection method can refer to the prior art. When the rubber roller 153 swings inward to a certain extent, the return spring 156 is gradually compressed or tightened. Under no external force, the return spring 156 can make the rubber roller 153 swing outward.

[0059] The bottom of the inner cylinder 12 is provided with a through hole 154 with a ramp 155, which gradually narrows inward from top to bottom. The rubber roller 153 passes through the through hole 154 and extends into the inner cylinder 12. The rubber roller 153 is provided with several gathering wheels 157, and the rubber roller 153 is provided with a slope surface 158 that matches the ramp 155. When the gathering nut 152 drives the rubber roller 153 to descend, the rubber roller 153 swings inward under the combined action of the ramp 155 and the slope surface 158, so that the gathering wheels 157 are close to the umbrella surface. When the gathering nut 152 drives the rubber roller 153 to rise, the rubber roller 153 swings outward under the action of the return spring 156, so that the gathering wheels 157 are away from the umbrella surface.

[0060] Furthermore, since the umbrella canopy protrudes significantly, when tidying up the umbrella, it is generally necessary to press the canopy together clockwise or counterclockwise to make the umbrella neater and flatter after tidying. If the rubber roller 153 and the umbrella can only move relative to each other, the umbrella can only be gathered in the middle, but the canopy cannot be tidied. Therefore, in this embodiment, the following technical solution is provided, which can both gather the umbrella ribs inward and tidy up the canopy: The umbrella folding device 10 includes a first state and a second state. When the umbrella folding device 10 is in the first state, the inner cylinder 12, the tightening screw 151, the tightening nut 152, and the rubber roller 153 can rotate synchronously. When the umbrella folding device 10 is in the second state, the inner cylinder 12 and the outer cylinder 11 are locked, the tightening screw 151 can drive the tightening nut 152 and the rubber roller 153 to move up and down, and the clamping mechanism 13 can rotate in the same direction as the tightening screw 151.

[0061] The above solution can be implemented using, but is not limited to, the following methods: Please refer to... Figure 8 , Figure 9 As shown, the umbrella retractor 10 also includes a conversion mechanism 17, which includes a locking ring 170, a swing arm 171, a conversion spring 172, and a lifting member 173.

[0062] The locking ring 170 is coaxially disposed inside the outer cylinder 11 and near the bottom end of the inner cylinder 12. Several locking teeth 174 are provided on the bottom side of the locking ring 170.

[0063] A swing arm 171 is arranged radially along the inner cylinder 12, and its middle part is swayably positioned at the bottom end of the inner cylinder 12. The outer end of the swing arm 171 is provided with a locking head 175 that engages with a locking tooth 174. Both the locking tooth 174 and the locking head 175 can have a serrated structure. A conversion spring 172 is connected to both the inner cylinder 12 and the swing arm 171, causing the locking head 175 to tend to press against the locking ring 170. The conversion spring 172 can be a compression spring, a tension spring, etc. After the locking head 175 engages with the locking tooth 174, the inner cylinder 12 and the outer cylinder 11 are fixed, and they cannot rotate relative to each other.

[0064] The lifting component 173 is fixedly mounted on the top of the coiling screw 151 and can extend and retract vertically. The bottom of the inner cylinder 12 is provided with a transmission hole 124 that matches the extension end of the lifting component 173. The transmission hole 124 can be a square hole, and the cross-section of the extension end of the lifting component 173 can be square. When the lifting component 173 rises, it drives the swing arm 171 to swing, so that the locking head 175 disengages from the locking tooth 174. At this time, the lifting component 173 is inserted into the transmission hole 124, so that the inner cylinder 12, the coiling screw 151, the coiling nut 152, and the rubber roller 153 can rotate synchronously. When the lifting component 173 descends, the swing arm 171 is reset under the action of the conversion spring 172, the locking head 175 locks with the locking tooth 174, the inner cylinder 12 is fixed to the outer cylinder 11, and the lifting component 173 disengages from the transmission hole 124. The coiling screw 151 can drive the coiling nut 152 and the rubber roller 153 to rise and fall. Specifically, the engagement of the lifting component 173 with the swing arm and transmission hole 124 can adopt, but is not limited to, the following schemes: The lifting component 173 adopts a telescopic cylinder, which includes a fixed cylinder and a telescopic arm. The telescopic arm is telescopically installed inside the fixed cylinder. A stop can be provided on one side of the telescopic arm. The telescopic end of the telescopic arm has a square structure. When the telescopic arm rises, the stop can abut against the inner end of the swing arm 171 and push it to rise, while the outer end of the swing arm 171 descends until the locking head 175 disengages from the locking tooth 174. When the telescopic arm rises to a certain height, the telescopic end of the telescopic arm inserts into the transmission hole 124, and the lifting component 173 can drive the inner cylinder 12 to rotate. When the telescopic arm descends, the telescopic arm descends, and the telescopic end gradually disengages from the transmission hole 124. At the same time, the stop gradually descends. At this time, the conversion spring 172 causes the outer end of the swing arm 171 to rise and the inner end to descend until the locking head 175 engages with the locking tooth 174 and the stop disengages from the swing arm 171.

[0065] In other embodiments, the umbrella retraction mechanism 15 may also adopt other structures, such as the umbrella retraction mechanism 15 being unable to rise or fall, but only able to move towards the center.

[0066] In some embodiments, the inner cylinder 12 may also include a cylinder body 122 and a turntable 123. The turntable 123 is rotatably disposed on the inner bottom of the cylinder body 122 and is used to support the umbrella tip. The turntable 123 is provided with a clamping member for holding the umbrella tip. The turntable 123 is drivenly connected to the gathering screw 151, and the rotating seat 130 is driven to rotate via the umbrella. Alternatively, the turntable 123 is not connected to the gathering screw 151, and the rotating seat 130 is driven to rotate by a tidying motor. The axis of the gathering wheel 157 is inclined and out of plane with respect to the center line of the inner cylinder 12. When the umbrella folder 10 is in the second state, the gathering wheel 157 rolls in a spiral direction on the umbrella surface. Of course, in other embodiments, the turntable 123 may not be provided. Since the contact area between the umbrella tip and the inner cylinder 12 is small, the friction force is small when they rotate relative to each other and can be ignored. The rotating seat 130 is driven to rotate by the tidying motor.

[0067] Based on everyday experience, when an umbrella is closed, part of the canopy is pressed down by the ribs, resulting in poor canopy alignment. In some implementations, this can be improved by the following methods: Please refer to... Figure 3 As shown, the umbrella folder 10 also includes an umbrella surface straightening assembly 18, which includes a blower, an air pipe 180, and several suction nozzles 181. The blower is located inside the inner cylinder 12, and the suction nozzles 181 are evenly distributed along the circumference of the inner cylinder 12 on its inner surface. In the same cross-section, the orientation of the suction nozzles 181 is inclined relative to the radial direction of the inner cylinder 12, and the inclination directions of the several suction nozzles 181 are rotationally symmetrical. The blower and the suction nozzles 181 are connected through the air pipe 180. When the clamping assembly is in the closed state, the blower operates, and the suction nozzles 181 can draw air and attract the umbrella surface to pull out the umbrella surface between any two adjacent umbrella ribs, while the second clamping mechanism 135 gradually retracts. Before closing the umbrella ribs, the umbrella surface is first sucked out to ensure that the umbrella surface is not pressed by the umbrella ribs. The umbrella surface closing mechanism 15 can fold the umbrella surface clockwise or counterclockwise for a neater result. The suction nozzle 181 is tilted so that the umbrella surface can rotate clockwise or counterclockwise. When closing and pressing the umbrella surface and ribs together, simply rotate the umbrella in the opposite direction of the rotation to neatly fold the surface. The exhaust fan structure can refer to existing technology. The air pipe 180 is connected to both the exhaust port of the exhaust fan and the suction nozzle 181, which is not shown in the figure. The suction nozzle 181 can adopt the structure of existing technology. Generally speaking, in order to make the suction stronger, the diameter of the suction nozzle 181 is relatively small. Of course, it is also possible to use a section of ordinary plastic tube with the same diameter for the suction nozzle 181.

[0068] In addition, in some embodiments, the umbrella closer 10 may also include a ring ejection mechanism 19, which is disposed at the top of the inner cylinder 12 and is used to hold and release the rubber ring to tighten the umbrella canopy.

[0069] The structure of the ring ejection mechanism 19 can refer to existing technology, or the following solution can be adopted: Please combine Figure 10 As shown, the ring ejection mechanism 19 includes a pre-placement component and an ejection component 191. The pre-placement component includes several inclined members 192, which are inclinedly disposed inside the inner cylinder 12. Each inclined member 192 has a groove that slopes inward from top to bottom and is open at the bottom. The grooves of several inclined members 192 are used to place the rings. In actual use, the rings need to be placed in the grooves in advance, and each ring is embedded in the grooves of several inclined members 192. The ejection component 191 is disposed below the inclined members 192 and is used to make the rings disengage from the grooves one by one and tighten them on the umbrella surface.

[0070] The structure of the pop-out component 191 can adopt, but is not limited to, the following scheme: Each pop-out component 191 corresponds one-to-one with the tilting component 192. Each pop-out component 191 includes a bracket 193, a swinging component 194, and a control component 195. The bracket 193 is disposed in the inner cylinder 12, the swinging component 194 is swingably disposed on the bracket 193, and the structure of the control component 195 is not limited. For example, the control component 195 can adopt a solenoid valve, a telescopic cylinder, or other structures. The control component 195 is used to control the swinging component 194 to swing. During the swinging process of the swinging component 194, the opening of the tilting component 192 can be opened or closed.

[0071] In some embodiments, the umbrella retractor 10 may further include several alarm components, not shown in the figure. Each alarm component includes a column, a vacuum suction cup, an alarm, a trigger, and a return spring 156. The column is fixed to the bottom of the support leg 110 and has a vertical cylindrical cavity. The vacuum suction cup is located at the bottom of the column and has a conical vacuum cavity. The alarm is located on the column and has a control switch and a trigger switch. The control switch is configured for manual control. When both the control switch and the trigger switch are turned on simultaneously, the alarm will sound. When either the control switch or the trigger switch is turned off, the alarm will not sound. The trigger switch is located within the cylindrical cavity, and the trigger is vertically and vertically inserted into the cylindrical cavity with a sealed contact. The bottom end of the trigger extends into the conical vacuum cavity. When the vacuum suction cup deforms and adheres to the ground, the conical vacuum cavity deforms and the bottom end of the column moves downward, causing the trigger to rise relative to the column and close the trigger switch. When the vacuum suction cup returns to its original position, the conical vacuum cavity returns to its original shape and the bottom end of the column moves upward, triggering the trigger.

[0072] The method of using the umbrella retractor 10 provided in this embodiment is as follows:

[0073] Place the umbrella into the inner tube 12, with the tip of the umbrella supported on the turntable 123;

[0074] When the first clamping mechanism 134 is working, the servo motor 131 drives the clamping blades 133 to rotate through the transmission assembly, so that several clamping blades 133 are retracted and the umbrella handle is clamped and fixed.

[0075] Release the umbrella;

[0076] The lifting component 173 rises, causing the swing arm 171 to swing and the locking head 175 to disengage from the locking tooth 174, thus unlocking the inner cylinder 12 and the outer cylinder 11, allowing the inner cylinder 12 to rotate relative to the outer cylinder 11; the telescopic end of the lifting component 173 is inserted into the transmission hole 124 at the bottom of the inner cylinder 12, so that the inner cylinder 12 and the umbrella surface gathering mechanism 15 are fixed as a whole, and the two can rotate synchronously.

[0077] When the retracting motor 150 is working, it drives the inner tube 12 to rotate. At this time, the retracting nut 152 can only rotate synchronously with the retracting screw 151 and the retracting nut 152 cannot rise or fall. Therefore, the inner tube 12 can drive the umbrella to rotate and shake off the rainwater on the umbrella surface.

[0078] The lifting component 173 descends, causing the swing arm 171 to swing and the locking head 175 to engage with the locking tooth 174, locking the inner cylinder 12 and the outer cylinder 11, that is, the inner cylinder 12 cannot rotate relative to the outer cylinder 11; the telescopic end of the lifting component 173 disengages from the transmission hole 124 at the bottom of the inner cylinder 12, so that the inner cylinder 12 and the coiling screw 151 can rotate relative to each other.

[0079] When the exhaust fan is working, it draws air through the suction nozzle 181, which can suck the umbrella surface out of the umbrella ribs.

[0080] When the retracting motor 150 is working, due to the limiting effect of the rubber roller 153 and the through hole 154, the rubber roller 153 and the retracting nut 152 can only move up and down and cannot rotate with the retracting screw 151; under the combined action of the slope 155 and the slope surface 158, the top of the rubber roller 153 gradually retracts inward; at this time, the retracting motor can drive the clamping mechanism 13 to rotate, that is, the umbrella rotates relative to the inner cylinder 12 and the rubber roller 153, and the retracting wheel 157 on the rubber roller 153 rolls in a spiral direction on the umbrella surface, folding the umbrella ribs and the umbrella surface together;

[0081] The control component 195 controls the swing component 194 to swing, so that the swing component 194 exposes the bottom end of the groove of the tilting component 192. The collar itself is elastic and can disengage from the groove and retract to fix the umbrella. Then the control component 195 controls the swing component 194 to swing in the opposite direction so that the swing component 194 closes the bottom end of the groove of the tilting component 192.

[0082] Depending on the different product structure plans, the above steps can be added, removed, or modified.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
