Description

Technical Field

[0001] This application relates to the field of hair dryers, and particularly to a lightweight and high-strength hair dryer housing structure. Background Art

[0002] A hair dryer, also known as a hair blower, is a small household appliance composed of a group of heating wires and a high-speed small fan. The principle of a hair dryer is that the motor directly drives the rotor to drive the fan blades to rotate. When the fan blades rotate, air is inhaled from the air inlet, and the centrifugal air flow formed thereby is blown out from the front nozzle of the air duct; when the air passes through, if the heating wire on the heating bracket installed in the nozzle is energized and heated, the blown air is hot air; if the selection switch does not energize the heating wire to heat, the blown air is cold air; the hair dryer is used to achieve the purpose of drying and shaping in this way.

[0003] The existing hair dryer structures all include a head and a handle. In order to achieve the effect of lightweight, the housings of the head and the handle are generally made of plastic. However, after long-term use, the plastic housings often become brittle due to aging, resulting in a poor overall strength and being easily broken during use. After the housing is broken, it needs to be replaced as a whole, and the maintenance cost is relatively high. Utility Model Content

[0004] In order to improve the problem that the existing housing needs to be completely replaced after being damaged, this application provides a lightweight and high-strength hair dryer housing structure.

[0005] This application provides a lightweight and high-strength hair dryer housing structure, adopting the following technical solutions:

[0006] A lightweight and high-strength hair dryer housing structure includes a grip portion and a head portion. The grip portion is inserted into the head portion. The grip portion includes a base and a plurality of fixing strips arranged around the top of the base. A plurality of movable strips are provided inside the plurality of fixing strips at the top of the base, and the movable strips and the fixing strips are arranged in one-to-one correspondence; a connecting rod is provided between the movable strip and the fixing strip, and a clamping plate is inserted between adjacent two connecting rods, and the side edges in the height direction of the clamping plate are clamped between the movable strip and the fixing strip.

[0007] By adopting the above technical solutions, a plurality of movable strips and fixing strips form a framework, and then a plurality of clamping plates are sequentially inserted between the movable strips and the fixing strips to form a complete grip portion. The cooperation between the fixing strips and the movable strips can reliably fix the clamping plates, ensuring that the grip portion has sufficient strength. Moreover, when any one of the clamping plates is aged or damaged, it can be replaced separately, enabling the rapid replacement of the clamping plates and reducing the replacement cost.

[0008] Optionally, the base is in a circular ring shape, and a plurality of the fixing bars are evenly dispersed outside the axis of the base, and the outer wall of the fixing bar is flush with the outer wall of the base.

[0009] By adopting the above technical solution, the base serves to install the fixing bars, ensuring that the fixing bars can reliably cooperate with the movable bars as a foundation and form a reliable fixation for the clamping plates. The plurality of fixing bars are arranged at equal intervals, enabling the sizes of the plurality of clamping plates to be consistent, and improving the user's gripping feel and user experience.

[0010] Optionally, a groove and a limiting ring are provided at the top of the movable bar. A plurality of the grooves are distributed within the same circumference, and the limiting ring is adaptively clamped within the plurality of grooves; the handle portion further includes a top seat, the top seat is sleeved outside the plurality of fixing bars, the lower part of the top seat is threadedly connected to the plurality of fixing bars, and the upper part of the top seat is inserted into the machine head portion.

[0011] By adopting the above technical solution, after the limiting ring is placed in the groove inside the top of the movable bar, the plurality of movable bars cannot move radially, thus playing a role in limiting the movable bar. When the movable bar is limited, the upper end of the fixing bar cannot bend radially either. In this way, it is ensured that the top seat can be quickly screwed outside the plurality of fixing bars, facilitating the connection of the handle portion and the machine head portion through the top seat.

[0012] Optionally, a through hole is provided on the fixing bar. One end of the connecting rod is connected to the movable bar, and the other end of the connecting rod passes through the through hole. A limiting groove is provided on one side of the connecting rod located inside the through hole, and a limiting strip is provided on the inner wall of the through hole. The limiting strip slidably fits within the limiting groove; a threaded hole is provided on one side end face of the connecting rod located inside the through hole, and an adjusting screw is adaptively screwed within the threaded hole. The adjusting screw only rotates around its own axis within the through hole.

[0013] By adopting the above technical solution, after the adjusting screw is driven, the adjusting screw can only rotate around its own axis and cannot move horizontally along its own axis. At the same time, the adjusting screw is in a threaded connection with the threaded hole on the connecting rod, and the connecting rod cannot rotate around its own axis under the cooperation of the limiting strip and the limiting groove. In this way, the rotation of the adjusting screw can drive the connecting rod to move horizontally along its own axis. When the connecting rod moves horizontally, the distance between the movable bar and the fixing bar can also be adjusted accordingly, thereby facilitating the insertion and locking of the clamping plate.

[0014] Optionally, the length of the threaded hole is greater than the length of the adjusting screw.

[0015] By adopting the above technical solution, it is ensured that the threaded hole has sufficient length to cooperate with the adjusting screw rod, thereby increasing the adjustment range of the movable strip, and then enabling clamping plates of different thicknesses, improving the compatibility of the handle portion with the clamping plate.

[0016] Optionally, a sealing block is provided at one end of the perforation away from the movable strip, the sealing block covers the perforation, an annular accommodating groove is provided on the inner wall of the perforation, a snap ring is provided on the outer wall of the sealing block, the snap ring is rotatably fitted in the accommodating groove, the adjusting screw rod is fixedly connected to the middle of the sealing block, and an internal hexagonal hole is provided on the side of the sealing block flush with the fixed strip.

[0017] By adopting the above technical solution, when an internal hexagonal wrench is inserted into the internal hexagonal hole and the sealing block is rotated by the internal hexagonal wrench, the snap ring will also rotate in the accommodating groove. With the cooperation of the snap ring and the accommodating groove, the sealing block can only rotate and cannot move horizontally. In this way, the adjusting screw rod can be reliably driven to rotate by the sealing block, thereby increasing the adjustment speed of the movable strip.

[0018] Optionally, shock pads are provided on the side of the movable strip facing the fixed strip and on the side of the fixed strip facing the movable strip.

[0019] By adopting the above technical solution, after the movable strip is locked, both sides of the clamping plate are in contact with a shock pad, thereby improving the earthquake resistance performance of the clamping plate during use.

[0020] Optionally, a filter net is rotatably fitted on the outside of the base, a plug cap is rotatably fitted on the inside of the filter net, a wire passing hole is provided on the plug cap, and a power cord passes through the wire passing hole into the handle portion and the machine head portion.

[0021] By adopting the above technical solution, the setting of the filter net can purify the air inhaled into the machine head portion, prevent dust from accumulating on the blowing component and the heating component in the machine head portion, and ensure that the blowing component and the heating component can be in a reliable working state; the plug cap plays a role in sealing the end face of the filter net and facilitates the introduction of the power cord.

[0022] In summary, the present application has the following beneficial effects:

[0023] 1. By rotating the sealing block, the driving effect on the adjusting screw rod is realized. Under the driving effect of the adjusting screw rod, the position of the movable strip can be reliably adjusted. Then, a clamping plate can be quickly inserted between the movable strip and the fixed strip, and the movable strip is locked by the adjusting screw rod to realize the reliable fixation of several clamping plates, effectively improving the overall strength of the handle portion. And after one clamping plate is damaged, it can be quickly replaced, thereby reducing the maintenance cost.

[0024] 2. The bottom of the fixed bar is fixedly connected to the base, and the top of the fixed bar is suspended. A limiting ring is provided at the top of the movable bar. Under the limiting action of the limiting ring and the screwing action of the top seat, the upper part of the fixed bar can also be in a reliably fixed state, further improving the overall strength of the handle part.

[0032] The following Figures 1-6 further describes the present application in detail.

[0033] Figure 1 is a schematic perspective view of the present application, Figure 2 is a schematic perspective view of the handle part. Refer to Figure 1 and Figure 2, A lightweight and high-strength hair dryer housing structure, including a handle part 1 and a machine head part 2. The handle part 1 is a vertical tubular shape. The handle part 1 includes a base 11, a top seat 16, and a number of fixed bars 12 and movable bars 13 arranged between the base 11 and the top seat 16. The base 11 is in a circular ring shape. One end of the fixed bar 12 is fixedly connected to the top of the base 11. A number of fixed bars 12 are evenly spaced along the axial direction on the top of the base 11. That is to say, a number of fixed bars 12 are evenly distributed on the top of the base 11. Moreover, the outer sides of a number of fixed bars 12 are flush with the outer side of the base 11, improving the aesthetics after the connection of the fixed bar 12 and the base 11. The top seat 16 is in a convex shape. The lower part of the top seat 16 is screwed on the outer sides of a number of fixed bars 12 through threads, and the upper part of the top seat 16 is inserted into the inner side of the machine head part 2 to realize the fixation of the handle part 1 and the machine head part 2. Further, a groove 131 is provided at the top of each of the movable bars 13. A number of grooves 131 are arranged within the same circumference. In this way, a limiting ring 132 can be directly placed in a number of grooves 131 and form a limiting effect on the movable bar 13, ensuring that when the top seat 16 is screwed with the fixed bar 12, the fixed bar 12 and the movable bar 13 are both in a fixed state, and thus ensuring a reliable connection between the top seat 16 and the fixed bar 12.

[0034] Figure 3 is a reference diagram of the exploded state of the handle part, Figure 4 is Figure 3 the enlarged structural schematic diagram of part A in Figure 3 and Figure 4 , a number of movable bars 13 are provided inside a number of fixed bars 12. A number of movable bars 13 are arranged in one-to-one correspondence with a number of fixed bars 12. A connecting rod 14 is provided between the movable bar 13 and the fixed bar 12. One end of the connecting rod 14 is fixedly connected to the middle of the movable bar 13, and the other end of the connecting rod 14 is movably connected to the middle of the fixed bar 12. A through hole 121 is provided on the side of the fixed bar 12 facing the movable bar 13. The connecting rod 14 is inserted through the through hole 121. A sealing block 123 is provided on the inner side of the end of the through hole 121 far from the movable bar 13. A clamping ring 1231 is provided on the outer wall of the sealing block 123. An annular accommodating groove 1211 is provided on the inner wall of the end of the through hole 121 far from the movable bar 13. The clamping ring 1231 is adaptively clamped in the accommodating groove 1211, and the clamping ring 1231 can rotate along its own axis in the accommodating groove 1211 but cannot be displaced to the outside of the accommodating groove 1211. A pair of limiting grooves 141 are provided on the inner wall of the end of the through hole 121 close to the movable bar 13. A pair of limiting bars 122 are provided on the outer wall of the end of the connecting rod 14 inserted through the through hole 121. One limiting bar 122 is adaptively arranged in one limiting groove 141, and the other limiting bar 122 is adaptively arranged in the other limiting groove 141. The limiting bar 122 can slide along its own axis direction in the limiting groove 141 but cannot be displaced to the outside of the limiting groove 141.

[0035] Figure 5 is a schematic perspective view of the sealing block and the connecting rod, Figure 6 is a schematic internal structure view of the movable bar and the fixed bar. Refer to Figure 5 and Figure 6 , on one side of the sealing block 123, an adjusting screw 17 is provided. The adjusting screw 17 is coaxially arranged with the through hole 121. On the other side of the sealing block 123, it is flush with the outer wall of the fixed bar 12 and is provided with an internal hexagonal hole 1232. One end face of the connecting rod 14 located in the through hole 121 is provided with a threaded hole 142. The adjusting screw 17 is adaptively screwed into the threaded hole 142. The length of the threaded hole 142 is greater than the length of the adjusting screw 17, ensuring that the adjusting screw 17 can be completely screwed into the threaded hole 142, and ensuring the maximum relative stroke between the adjusting screw 17 and the threaded hole 142.

[0036] After inserting an internal hexagonal wrench into the internal hexagonal hole 1232, the sealing block 123 can be smoothly driven, so that the sealing block 123 can reliably rotate in the through hole 121. At the same time, under the cooperation of the snap ring 1231 and the receiving groove 1211, the sealing block 123 and the adjusting screw 17 can only rotate circumferentially and cannot move axially. In this way, the adjusting screw 17 will rotate in the threaded hole 142, and the connecting rod 14 cannot rotate circumferentially under the limiting action of the limiting strip 122 and the limiting groove 141. In this way, the rotation of the adjusting screw 17 and the threaded connection between the adjusting screw 17 and the connecting rod 14 will form a linear driving action on the connecting rod 14, that is, after rotating the sealing block 123, the connecting rod 14 moves in the horizontal direction and drives the movable bar 13 away from or close to the fixed bar 12.

[0037] Refer to Figure 5, the movable bar 13, the corresponding fixed bar 12, and the connecting rod 14 form a positioning area 3. Under the partitioning effect of the connecting rod 14, the positioning area 3 is divided into a left area and a right area. A handle portion 1 includes a plurality of positioning areas 3. A clamping plate 15 is inserted between the left area of one positioning area 3 and the right area of another positioning area 3. When inserting the clamping plate 15, the sealing block 123 can be rotated to drive the movable bar 13 away from the fixed bar 12 to increase the thickness of the positioning area 3, facilitating the quick insertion of the clamping plate 15. After the clamping plate 15 is inserted, the sealing block 123 is rotated in the reverse direction to drive the movable bar 13 closer to the fixed bar 12 to reduce the thickness of the positioning area 3, thereby realizing the locking effect on the clamping plate 15. Further, shock pads 18 are provided on the side of the movable bar 13 facing the fixed bar 12 and the side of the fixed bar 12 facing the movable bar 13. After the clamping plate 15 is installed, both sides of the clamping plate 15 in the height direction are wrapped by the shock pads, thereby improving the seismic performance of the clamping plate 15. When the clamping plate 15 is damaged due to aging or collision, the damaged clamping plate 15 can be replaced individually, reducing the maintenance cost. Moreover, after the handle portion 1 is installed, the fixed bar 12 protrudes to the outside of the clamping plate 15. In this way, a corrugated structure is formed between the outer wall of the fixed bar 12 and the outer wall of the clamping plate 15, so that the handle portion 1 will not slip when being held. Further, when it drops during use, the fixed bar 12 with a smaller surface area will contact the ground first, reducing the probability of damage to the clamping plate 15 and improving the overall strength.

[0038] See Figure 3 , a filter net 19 is rotatably fitted on the outside of the base 11, and a plug cap 191 is rotatably fitted on the inside of the filter net 19, ensuring that the external air needs to pass through the filtration of the filter net 19 before entering the handle portion 1 and the machine head portion 2. A wire passing hole 1910 is provided on the plug cap 191, and the power cord passes through the wire passing hole 1910 into the handle portion 1 and the machine head portion 2, thereby reliably supplying power to the blowing component and the heating component in the machine head portion 2.

[0039] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
