Description

TECHNICAL FIELD

[0001] The utility model relates to garden tool technical field, specifically, relate to a protection assembly and blow equipment. BACKGROUND

[0002] At present, the garden blower usually will be assembled with the longer blow nozzle, and along the direction of the blow nozzle's air nozzle to the handheld end, the diameter of the blow nozzle will gradually reduce, that is, the diameter of the blow nozzle's air nozzle is minimum, thereby can facilitate the staff to extend the blow nozzle into the shrub, leaf and carry out the corresponding blowing operation, but in the actual operation, the air nozzle of the blow nozzle is easy to touch, even collide with the blown object, and further cause the air nozzle damage (such as wear, even concave etc.

[0003] In the prior art, the air nozzle of the blow nozzle is usually assembled with a metal ring through welding or integral molding, the metal ring can contact with the blown object in advance when the air nozzle touches or even collides with the blown object, so as to play the role of protection and prolong the service life of the blow nozzle.

[0004] However, the metal ring as a protection assembly has the following two problems in actual use:

[0005] Problem one: the integral structure of the metal ring can only be replaced as a whole when damaged, even if the damaged area is small, thereby increasing the maintenance cost;

[0006] Problem two: the welded or integrally formed metal ring is difficult to disassemble, if the metal ring is damaged, the staff can only replace the blow nozzle as a whole, further increasing the maintenance cost. UTILITY MODEL CONTENTS

[0007] Therefore, the utility model aims to provide a protection assembly and blow equipment with small disassembly difficulty and low maintenance cost.

[0008] In order to achieve the above purpose, the technical scheme provided by an embodiment of the utility model is as follows:

[0009] The protective assembly comprises: a protective structure, which is detachably arranged at an air outlet of an air outlet structure, at least part of the protective structure is located at the outer circumferential side of the air outlet structure, and the protective structure is used for protecting the air outlet structure; a fixing structure, which is detachably arranged on the air outlet structure and is used for fixing the protective structure; wherein the protective structure is at least two, and the at least two protective structures surround the air outlet structure. When the protective structure is damaged, the fixing structure and the protective structure can be sequentially disassembled by the worker to maintain and replace the protective structure, thereby reducing the disassembly difficulty of the protective assembly, avoiding the problem of replacing the whole air outlet structure caused by the disassembly difficulty of the protective structure, and preliminarily reducing the maintenance cost of the protective assembly. The protective assembly actually adopts a modular design, that is, a plurality of protective structures are used to protect the air outlet structure in a whole circle, and the above arrangement enables the worker to replace the protective structure locally according to the actual damage of the protective structure, thereby further reducing the maintenance cost of the protective assembly.

[0010] Further, the protective structure has a matching recess for the edge of the air outlet to extend into, and the protective structure is hung at the air outlet through the matching recess; or the protective structure has a matching protrusion for extending into the recess at the air outlet, and the protective structure is hung at the air outlet through the matching protrusion. While realizing the detachable assembly between the protective structure and the air outlet structure, the above arrangement also enables the worker to operate the protective structure to move along the edge of the air outlet, thereby facilitating the worker to adjust the position of each protective structure at any time during the assembly of the plurality of protective structures, and reducing the assembly difficulty of the worker.

[0011] Further, the protective structure has a matching recess, and the protective structure further comprises: a protective part, which is located at the outer circumferential side of the air outlet structure and is used for protecting the air outlet structure; and an extension part, which is arranged on the protective part and surrounds the matching recess with at least part of the protective part. In this way, the above arrangement makes the structure of the protective structure and the forming method of the matching recess more simple, thereby reducing the processing cost of the protective structure and the processing difficulty of the worker.

[0012] Further, the extension part is located in the air outlet, the protective structure further has a first magnetic attraction part on the protective part and / or the extension part, and the protective structure is clamped on the air outlet structure through the magnetic attraction force between the protective part and the extension part. After the worker assembles one protective structure, the protective part and the extension part of the protective structure can be pinched to make the protective part and the extension part magnetically attracted through the magnetic attraction force of the first magnetic attraction part, thereby generating a nearly clamped fixing effect. The above arrangement can preliminarily fix the assembled protective structure to avoid affecting the assembly of other protective structures, thereby further reducing the assembly difficulty of the worker.

[0013] Further, the protection assembly further comprises a magnetic attraction structure arranged on the protection part and / or the extension part to form a first magnetic attraction part. In this way, the first magnetic attraction part is formed by the magnetic attraction structure, which not only makes the overall material of the protection structure unrestricted, but also reduces the processing difficulty and cost of the protection structure.

[0014] Further, the fixing structure is annular and is sleeved on the at least two protection structures, and during movement of the fixing structure in a direction away from the air outlet along the axis direction of the air outlet structure, the fixing structure fixes the protection structures on the air outlet structure through the extrusion force between the fixing structure and the air outlet structure. The annular fixing structure can synchronize the fixing of multiple protection structures, thereby greatly reducing the fixing difficulty of the multiple protection structures. On the other hand, the fixing structure can be adapted to air outlet structures of different specifications and sizes. When facing protection structures of different specifications and sizes, the fixing structure only needs to be sleeved at different positions to ensure that it still achieves the fixing effect. At the same time, the above arrangement greatly reduces the difficulty of disassembling and assembling the fixing structure for the worker, thereby improving the efficiency of the worker in disassembling and assembling the fixing structure.

[0015] Further, the fixing structure has a second magnetic attraction part, and the fixing structure is magnetically attracted to the protection part and / or the extension part and / or the first magnetic attraction part through the second magnetic attraction part. In this way, the above arrangement can assist in fixing the fixing structure through the magnetic attraction force to avoid the fixing structure from falling off, thereby improving the assembly stability of the fixing structure.

[0016] Further, the first magnetic attraction part is strip-shaped and extends along the axis direction of the air outlet structure. In this way, the above arrangement increases the magnetic attraction range of the first magnetic attraction part, that is, ensures that the fixing structure can be magnetically attracted to the first magnetic attraction part when sleeved at different positions, thereby further improving the assembly stability of the fixing structure.

[0017] Further, the protection part is plate-shaped, and the width of at least part of the protection part gradually decreases in a direction from one end of the protection part close to the air outlet to the other end. In this way, the above arrangement ensures that the width (area) of the protection part of the air outlet, which is relatively weak in structural strength, is large, thereby improving the protection effect of the protection part and prolonging the service life of the air outlet structure. On the other hand, the width (area) of the part of the protection part away from the air outlet is smaller, so as to reduce the material usage of the protection part and the processing cost of the protection part. At the same time, the above arrangement can also reduce the fitting area between the fixing structure and the protection structure to fully utilize the elastic deformation between them (in the space between two adjacent protection structures, the part with a reduced width will have a gap to facilitate deformation of the protection structure), thereby further improving the fixing reliability of the fixing structure.

[0018] Further, the outer circumferential surface of the protection part forms a polygon; or the outer circumferential surface of the protection part is formed by a curve; or the outer circumferential surface of the protection part is formed by a straight line and a curve connected with each other. In this way, the above-mentioned arrangement makes the structure of the protection part more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the workers.

[0019] Further, the outer circumferential surface of the protection structure forms a right-angled triangle, and one of the right-angled sides and the hypotenuse of the right-angled triangle is arranged close to the edge of the air outlet relative to the other right-angled side. In this way, the above-mentioned arrangement ensures that the part of the protection part close to the air outlet has a larger width (area) to ensure that it has a larger protection area; on the other hand, since the two right-angled sides of the right-angled triangle are perpendicular to each other, after one of them is aligned with the edge of the air outlet, the other can be parallel to the axis of the air outlet structure, at this time, the right-angled side can serve as a reference for the subsequent assembled protection structure, to further reduce the assembly difficulty of the workers and improve the assembly efficiency of the workers.

[0020] Further, the extension part is in the form of a plate, and the width of at least part of the extension part gradually decreases in the direction from one end of the extension part close to the air outlet to the other end. In this way, the above-mentioned arrangement not only enables the extension part to play a corresponding protection role in the air outlet, but also reduces the material usage of the extension part and the processing cost of the extension part.

[0021] Further, the material wear rate of the protection structure is less than the material wear rate of the air outlet structure, to improve the protection effect of the protection structure, avoid the protection structure from being worn out too early and causing the protection effect to fail, and thus prolong the service life of the protection structure.

[0022] Further, at least part of the fixing structure is made of an elastic material. In this way, during the process in which the workers set the fixing structure, the fixing structure can be elastically deformed to a certain extent, thereby improving the extrusion force between the fixing structure and the air outlet structure and further improving the fixing reliability of the fixing structure.

[0023] The utility model also provides a kind of blowing equipment, comprising: air outlet structure;Protection component is set on air outlet structure;Wherein, protection component is above-mentioned protection component. In this way, protection component can be quickly disassembled and can be replaced locally according to actual wear condition, to improve the maintenance efficiency of blowing equipment and reduce the maintenance cost of blowing equipment.

[0024] The utility model has the following beneficial effects: the detachable setting mode is adopted to the protection structure and fixed structure, namely when the protection structure is damaged, the staff can dismantle the fixed structure and protection structure in proper order to maintain and replace the protection structure, thereby the dismounting difficulty of the protection assembly is reduced, the problem of overall replacement of the air outlet structure caused by the dismounting difficulty of the protection structure is avoided, and the maintenance cost of the protection assembly is preliminarily reduced; the modular design mode is actually adopted to the protection assembly, namely the air outlet structure is protected in a whole circle by multiple protection structures, and the setting makes the staff replace locally according to the actual damage condition of each protection structure, further reduces the maintenance cost of the protection assembly, and thereby the problem of great dismounting difficulty and high maintenance cost of the protection structure at the air nozzle of the garden blower in the prior art is solved. Meanwhile, the staff can also adjust the setting number of the protection structure to adapt to the air outlet structures of different sizes, and thereby the versatility of the protection assembly is improved.

[0047] It should be noted that, in the case of no conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0048] The technical solutions in the utility model will be described below with reference to the drawings.

[0049] In order to solve the problem of high maintenance cost and difficult disassembly of the protection structure at the nozzle of the existing garden blower, the utility model provides a protection assembly and a blowing equipment. The blowing equipment comprises an air outlet structure 1 and a protection assembly, the protection assembly is arranged on the air outlet structure 1, and the protection assembly is the protection assembly.

[0050] In order to achieve the above purpose, the technical scheme provided by an embodiment of the utility model is as follows:

[0051] As shown in Figures 1 to 4 The utility model provides a protection assembly, as shown in Figure 3As shown, the protection assembly includes a protection structure 10 and a fixing structure 20, the protection structure 10 is detachably arranged at the air outlet 101 of the air outlet structure 1, and at least part of the protection structure 10 is located at the outer circumferential side of the air outlet structure 1 for protecting the air outlet structure 1. The fixing structure 20 is detachably arranged on the air outlet structure 1 for fixing the protection structure 10. Among them, the protection structure 10 is at least two, and the at least two protection structures 10 surround the air outlet structure 1.

[0052] In this way, the protection structure 10 and the fixing structure 20 in the embodiment are actually both arranged in a detachable manner, that is, when the protection structure is damaged, the worker can sequentially detach the fixing structure and the protection structure to repair and replace the protection structure, thereby reducing the disassembly difficulty of the protection assembly, avoiding the problem of replacing the entire air outlet structure caused by the disassembly difficulty of the protection structure, and preliminarily reducing the maintenance cost of the protection assembly; and the protection assembly actually also adopts a modular design, that is, a plurality of protection structures are used to protect the air outlet structure in a whole circle, and the above arrangement enables the worker to replace the protection structures locally according to the actual damage of each protection structure, further reducing the maintenance cost of the protection assembly, thereby solving the problem of high maintenance cost and high disassembly difficulty of the protection structure at the air outlet of the garden blower in the prior art. At the same time, the worker can also adjust the number of protection structures to adapt to air outlet structures of different sizes, thereby improving the versatility of the protection assembly.

[0053] In this embodiment, the air outlet structure 1 is the air outlet of the garden blower.

[0054] It should be noted that the use scenario of the protection assembly is not limited to this, and other air outlet structures with air outlets such as air outlet pipes can also be used.

[0055] It should be noted that the number of protection structures 10 in the embodiment is two or more, that is, while meeting the modular design, the worker can adaptively adjust the number of protection structures 10 assembled on the air outlet structure 1 according to the size of the air outlet structure 1 (such as Figure 3 and Figure 4 as shown).

[0056] As shown in Figure 1 , the protection structure 10 has a matching recess 11 for the rim at the air outlet 101 to extend into, and the protection structure 10 is hung at the air outlet 101 through the matching recess 11. In this way, while achieving detachable assembly between the protection structure 10 and the air outlet structure 1 through hanging cooperation, the above arrangement also enables the worker to operate the protection structure 10 to move along the rim of the air outlet 101, thereby facilitating the worker to adjust the position of each protection structure 10 at any time during the assembly of multiple protection structures 10, and reducing the assembly difficulty of the worker.

[0057] In other embodiments not shown in the accompanying drawings, the protective structure 10 has a mating protrusion for extending into a recess at the air outlet 101, and the protective structure 10 is hooked onto the air outlet 101 via the mating protrusion. This arrangement allows the actual structure of the protective structure 10 to be adaptively adjusted according to the structure of the air outlet structure 1, ensuring that the protective structure 10 can be hooked onto the air outlet structure 1, and also improving the processing flexibility of the workers.

[0058] like Figure 1 As shown, the protective structure 10 has a mating recess 11. The protective structure 10 also includes a protective portion 12 and an extension 13. The protective portion 12 is located on the outer periphery of the air outlet structure 1 to protect the air outlet structure 1. The extension 13 is disposed on the protective portion 12, and the mating recess 11 is formed around the extension 13 and at least a portion of the protective portion 12. This arrangement simplifies the structure of the protective structure 10 itself and the formation of the mating recess 11, thereby reducing the processing cost of the protective structure 10 and the processing difficulty for workers.

[0059] like Figure 1 As shown, the extension 13 is located inside the air outlet 101. The protective structure 10 also has a first magnetic attraction part 14 located on the protective part 12 and / or the extension 13. The protective structure 10 is clamped onto the air outlet structure 1 by the magnetic attraction force between the protective part 12 and the extension 13. In this way, after the worker assembles a protective structure 10, the protective part 12 and the extension 13 of the protective structure 10 can be pinched together, so that the protective part 12 is magnetically attracted to the extension 13 by the magnetic attraction force of the first magnetic attraction part 14, thereby producing a near-clamping fixing effect. The above-mentioned arrangement can initially fix the assembled protective structure 10 to prevent its movement from affecting the assembly of other protective structures 10, further reducing the assembly difficulty for the worker.

[0060] In this embodiment, the fixing structure 20 is detachably mounted on the protective part 12 to fix the protective structure 10 from the outside of the air outlet 101.

[0061] In this embodiment, the first magnetic attraction part 14 is located on the extension part 13. That is, the extension part 13 is magnetically attracted to the protective part 12 through the first magnetic attraction part 14, so as to fix the protective structure 10 from the inside of the air outlet 101. In turn, it cooperates with the fixing structure 20 to fix the protective structure 10 from both the inside and outside of the air outlet 101, thereby improving the fixing stability of the protective structure 10.

[0062] Specifically, the first magnetic attraction part 14 can also reduce the difficulty of disassembly for workers. That is, after disassembling the fixed structure 20, workers only need to slightly bend the protective part 12 to make it deform to overcome the magnetic attraction force, and then the protective structure 10 can be removed from the air outlet structure 1, which greatly improves the disassembly efficiency of workers.

[0063] like Figure 1 As shown, the protective assembly also includes a magnetic attraction structure 30, which is disposed on the protective portion 12 and / or the extension portion 13 to form a first magnetic attraction portion 14. In this way, forming the first magnetic attraction portion 14 by the magnetic attraction structure 30 not only makes the overall material of the protective structure 10 unrestricted, but also reduces the processing difficulty and processing cost of the protective structure 10.

[0064] In this embodiment, the protective structure 10 (protective part 12 and extension part 13) is made entirely of ferromagnetic material so as to magnetically attract each other with the magnetic attraction structure 30.

[0065] like Figure 2 and Figure 3 As shown, the fixing structure 20 is annular and sleeved on at least two protective structures 10. Along the axial direction of the air outlet structure 1, as the fixing structure 20 moves away from the air outlet 101, it secures each protective structure 10 to the air outlet structure 1 through the compressive force between itself and the air outlet structure 1. Thus, the annular fixing structure 20 can simultaneously fix multiple protective structures 10, greatly reducing the difficulty of fixing them; furthermore, it can adapt to air outlet structures 1 of different specifications and sizes, such as… Figure 3 and Figure 4 As shown, when faced with protective structures 1 of different specifications and sizes, simply fitting the fixing structure 20 to different positions ensures that the fixing effect is still achieved. At the same time, this design greatly reduces the difficulty for workers to assemble and disassemble the fixing structure 20, thus improving their efficiency.

[0066] In this embodiment, the fixing structure 20 is in the shape of a ring.

[0067] It should be noted that the shape of the fixed structure 20 is not limited to this, as long as it matches the shape of the outer peripheral surface of the air outlet structure 1.

[0068] In this embodiment, the fixing structure 20 has a second magnetic attraction part 21, which magnetically attracts the fixing structure 20 to the protective part 12 and / or the extension part 13 and / or the first magnetic attraction part 14. Thus, the above arrangement can assist in fixing the fixing structure 20 through magnetic attraction force, preventing the fixing structure 20 from falling off and thereby improving the assembly stability of the fixing structure 20.

[0069] In this embodiment, the fixing structure 20 is made entirely of ferromagnetic material, meaning that the assembled fixing structure 20 will magnetically attract the first magnetic attraction part 14. This arrangement simplifies the structure of the fixing structure 20, reducing its processing cost and the difficulty of processing for workers.

[0070] It should be noted that the structure of the fixing structure 20 is not limited to this. For example, the fixing structure 20 may also be provided with a magnetic attraction structure so that the fixing structure 20 magnetically attracts the protective part 12 and the extension part 13 and the first magnetic attraction part 14 made of ferromagnetic material.

[0071] like Figure 1 As shown, the first magnetic attraction part 14 is strip-shaped and extends along the axial direction of the air outlet structure 1. In this way, the above-mentioned arrangement increases the magnetic attraction range of the first magnetic attraction part 14, that is, it ensures that the fixing structure 20 can be magnetically attracted with the first magnetic attraction part 14 when it is sleeved in different positions, further improving the assembly stability of the fixing structure 20.

[0072] like Figure 1 As shown, the protective part 12 is plate-shaped, and at least a portion of the protective part 12 gradually decreases in width along the direction from one end near the air outlet 101 to the other end. This arrangement ensures, on the one hand, that the width (area) of the protective part 12 at the air outlet 101, where the structural strength is relatively weak, is large, thereby improving the protective effect of the protective part 12 and extending the service life of the air outlet structure 1; on the other hand, it makes the width (area) of the protective part 12 further away from the air outlet 101 smaller, reducing the amount of material used and lowering the processing cost of the protective part 12. Simultaneously, this arrangement also reduces the mating area between the fixing structure 20 and the protective structure 10, fully utilizing the elastic deformation between them (between two adjacent protective structures 10, the reduced width will create a gap to allow the protective structure 10 to deform), further improving the fixing reliability of the fixing structure 20.

[0073] Optionally, the outer periphery of the protective part 12 can be formed into a polygon; or, the outer periphery of the protective part 12 can be formed by curves; or, the outer periphery of the protective part 12 can be formed by interconnected straight lines and curves. In this way, the above-mentioned configuration makes the structure of the protective part 12 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the workers.

[0074] In this embodiment, the outer periphery of the protective structure 10 forms a right-angled triangle, with one right-angled side and the hypotenuse positioned relative to the edge of the other right-angled side near the air outlet 101. This arrangement ensures, on the one hand, that the portion of the protective part 12 near the air outlet 101 has a larger width (larger area), thus providing a larger protective area; on the other hand, since the two right-angled sides of the right-angled triangle are perpendicular, once one side is aligned with the edge of the air outlet 101, the other side can be parallel to the axis of the air outlet structure 1. In this case, the right-angled side can serve as a reference for the subsequent assembly of the protective structure 10, further reducing the assembly difficulty for workers and improving their assembly efficiency.

[0075] like Figure 1 As shown, the extension 13 is plate-shaped, and the width of at least a portion of the extension 13 gradually decreases along the direction from one end of the extension 13 near the air outlet 101 to the other end. In this way, the above arrangement not only enables the extension 13 to play a corresponding protective role within the air outlet 101, but also reduces the amount of material used in the extension 13 and lowers the processing cost of the extension 13.

[0076] In this embodiment, the structure of the extension 13 is the same as that of the protective part 12, so as to reduce the processing cost of the extension 13.

[0077] In this embodiment, the wear rate of the material of the protective structure 10 is less than that of the material of the air outlet structure 1, so as to improve the protective effect of the protective structure 10, avoid the protective structure 10 from wearing out prematurely and thus causing its protective effect to fail, thereby extending the service life of the protective structure 10.

[0078] In this embodiment, at least a portion of the fixing structure 20 is made of an elastic material. Thus, during the process of the worker installing the fixing structure 20, the fixing structure 20 can undergo a certain degree of elastic deformation, thereby increasing the compressive force between the fixing structure 20 and the air outlet structure 1, further improving the fixing reliability of the fixing structure 20.

[0079] In this embodiment, the fixing structure 20 is made of a ferromagnetic material with a high elastic modulus, which ensures that the fixing structure 20 can magnetically attract the magnetic structure 30 while allowing the fixing structure 20 to undergo a certain degree of elastic deformation.

[0080] Another embodiment of this utility model provides the following technical solution:

[0081] like Figure 5 and Figure 6As shown, the outer peripheral surfaces of the protective portion 12 and the extension portion 13 form an isosceles triangle. This arrangement makes the structures of the protective portion 12 and the extension portion 13 more flexible and versatile, adapting to different working conditions and usage requirements. Of course, this arrangement also reduces the amount of material used in the protective portion 12 and the extension portion 13, lowering the processing cost of the protective structure 10.

[0082] In this embodiment, the bottom edge of the protective part 12 is located near the edge of the air outlet 101.

[0083] Another embodiment of this utility model provides the following technical solution:

[0084] like Figure 7 and Figure 8 As shown, the outer peripheral surface of the protective part 12 is semi-circular, and the outer peripheral surface of the extension part 13 is also semi-circular. This arrangement makes the structure of the protective part 12 and the extension part 13 more flexible and versatile, adapting to different working conditions and usage requirements. Of course, this arrangement also reduces the amount of material used in the protective part 12 and the extension part 13, lowering the processing cost of the protective structure 10.

[0085] In this embodiment, the chord edge of the protective part 12 is provided near the edge of the air outlet 101.

[0086] Another embodiment of this utility model provides the following technical solution:

[0087] like Figure 9 and Figure 10 As shown, the outer peripheral surface of the protective part 12 forms an isosceles trapezoid, and the outer peripheral surface of the extension part 13 also forms an isosceles trapezoid. This arrangement makes the structure of the protective part 12 and the extension part 13 more flexible and versatile, adapting to different working conditions and usage requirements. Of course, this arrangement also reduces the amount of material used in the protective part 12 and the extension part 13, lowering the processing cost of the protective structure 10.

[0088] In this embodiment, the bottom edge of the protective part 12 is located near the edge of the air outlet 101.

[0089] The specific disassembly and assembly process of the protective components in the above embodiments is as follows:

[0090] First, the staff selects a certain number of protective structures 10 according to the specifications and dimensions of the air outlet structure 1. Then, they hang up one protective structure 10 and pinch the protective part 12 and the extension part 13 of the protective structure 10 together to fix it. The above process is repeated to hang up all the protective structures 10 in sequence. Finally, the fixing structure 20 is put on to complete the assembly of the protective components. When disassembling or repairing, it is only necessary to use tools to knock off the fixing structure 20, then bend the protective part 12 of the damaged protective structure 10 and remove the protective structure 10. Finally, a new protective structure 10 is reinstalled and the fixing structure 20 is put on.

[0091] It is evident that the protective components in the above embodiments of this application have at least the following advantages:

[0092] 1. Easy to disassemble and extremely efficient

[0093] For the protective structure 10, its hook-on installation method and magnetic fixing method can greatly reduce the time spent by the staff to adjust the position of multiple protective structures 10 and avoid the interference between multiple protective structures 10, which would increase the difficulty of installation. For the fixing structure 20, the nested assembly method is not only simple, but also can fix multiple protective structures 10 at the same time, thereby comprehensively improving the assembly efficiency of the protective components and reducing the installation difficulty of the protective components.

[0094] 2. Reduce the maintenance cost of duct structure

[0095] The detachable protective components can avoid the problem of replacing the entire duct structure caused by the integrated protective components in the prior art, thus initially reducing the maintenance cost of the duct structure; while the modular design of the protective structure 10 can further reduce the maintenance cost of the duct structure by allowing partial replacement of the protective components according to the actual damage.

[0096] 3. Extremely high assembly stability

[0097] Although a detachable design is adopted, the fixing design of the first magnetic attraction part 14 and the inner and outer sides of the air outlet 101 of the fixing structure 20 greatly improves the fixing reliability of the fixing structure 20. The magnetic attraction design of the fixing structure 20 further improves the fixing reliability of the fixing structure 20, greatly reduces the probability of the protective components falling off during use, and optimizes the user experience.

[0098] 4. Extremely high versatility

[0099] The modular design of the protective structure 10 and the ring-shaped design of the fixing structure 20 can both adapt to different specifications and sizes of the air outlet structure 1, making the protective components more versatile.

[0100] This utility model has at least the following beneficial effects:

[0101] Both the protective and fixed structures are detachable, meaning that when the protective structure is damaged, workers can sequentially disassemble both the fixed and protective structures for repair or replacement. This reduces the difficulty of disassembling the protective components and avoids the need to replace the entire air outlet structure due to the inability to disassemble the protective structure, thus initially reducing the maintenance cost of the protective components. Furthermore, the protective components employ a modular design, using multiple protective structures to provide complete protection for the air outlet structure. This design allows workers to replace specific protective structures based on their actual damage, further reducing maintenance costs and solving the problem of difficult and costly disassembly of the protective structure at the nozzle of existing garden blowers. Additionally, workers can adjust the number of protective structures to accommodate different sized air outlet structures, thereby improving the versatility of the protective components.
