The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0056] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0058] See appendix Figure 1 -Appendix Figure 17 This utility model proposes a shovel, which includes a housing 1, a box 3 and at least one magnetic element 4. The working blade 20 is installed on the housing 1. Specifically, a working end 10 can be provided at one end of the housing 1, and the working blade 20 is installed on the working end 10 of the housing 1 to facilitate the user to hold the shovel for use. The box 3 has a storage cavity 30 inside for storing spare blades 21, and the storage cavity 30 has an opening 300. When a user needs to replace the working blade 20 on the working end 10, they can take the spare blade 21 from the storage cavity 30 and install it on the working end 10. In order to fix the spare blade 21 stored in the storage cavity 30, a magnetic component 4 is set on the housing 1 or box 3 near the storage cavity 30, so that the magnetic attraction force of the magnetic component 4 can act on the spare blade 21 in the storage cavity 30. Thus, the spare blade 21 is fixed in the storage cavity 30 by the magnetic attraction force of the magnetic component 4. This ensures that when the user takes out any spare blade 21, the other spare blades 21 will not be pulled out of the storage cavity, thus preventing the blades from falling out when the user takes out the spare blades 21 in the storage cavity 30, thereby improving the user experience.

[0059] In some embodiments, the magnetic member 4 can be selected from magnetic structures such as permanent magnets, electromagnets, flexible magnetic blocks, composite magnetic blocks, etc. that have a magnetic adsorption force on the metal blade. In this embodiment, for structural and production cost considerations, a strip magnet in the permanent magnet is selected as the magnetic structure for actual application; it should be noted that the magnetic adsorption force of the magnetic member 4 on the spare blade 21 is greater than the sum of the total metal adsorption force and the total gravity between the spare blades 21 with the maximum allowable stacking number in the storage cavity 30. For example, when taking the first spare blade 21, the magnetic adsorption force of the magnetic member 4 needs to overcome the following acting forces: the metal adsorption force between the target spare blade 21 and the adjacent spare blade 21, and the gravity of the target spare blade 21 itself, so that when taking one spare blade 21, the other spare blades 21 stored in the storage cavity 30 will not be detached连带.

[0060] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , the storage cavity 30 includes multiple cavity walls. In this embodiment, the multiple cavity walls include two first cavity walls 301 and three second cavity walls 302. The two first cavity walls 301 are spaced apart and parallel to each other. The three second cavity walls 302 are adjacent in sequence, and the three second cavity walls 302 are connected to the two first cavity walls 301 at the same time to form the internal storage space of the storage cavity 30; as Figure 1 , Figure 11 , Figure 13 and Figure 14 shown, in some embodiments, the opening 300 can be opened on any one of the second cavity walls 302; as Figure 12 shown, in other embodiments, the opening 300 can be opened on any one of the first cavity walls 301; when the spare blade 21 is stored in the storage cavity 30, the two first cavity walls 301 are substantially perpendicular to the thickness direction of the spare blade 21, that is, the surface of the spare blade 21 is substantially parallel to the first cavity wall 301, and the three second cavity walls 302 are substantially parallel to the thickness direction of the spare blade 21, that is, the surface of the spare blade 21 is substantially perpendicular to the second cavity wall 302. It can be further understood that when the spatula is placed on the table, the surface of the spare blade 21 substantially fits the bottom first cavity wall 301, and the second cavity walls 302 are distributed on the side of the blade.

[0061] The magnetic member 4 can be installed at a position of the box body 3 or the housing 1 close to the storage cavity 30. In some embodiments, the magnetic member 4 can be selected to be installed on the cavity wall of the storage cavity 30. Specifically, the magnetic member 4 can be arranged on the surface of the cavity wall, in the interlayer of the cavity wall, etc. For example, the magnetic member 4 is installed in the interlayer of the cavity wall.

[0062] Refer to Figure 6 , Figure 11 Figure 13 , Figure 14 In some embodiments, the magnetic element 4 is specifically disposed on any one, two, or three of the second cavity walls 302. Since the magnetic element 4 is distributed on the second cavity walls 302, while fixing the spare blade 21 within the receiving cavity 30, the magnetic field direction of the magnetic element 4 is parallel to the upper and lower surfaces of the spare blade 21. This magnetizes the internal magnetic domains of the spare blade 21, forming a transverse magnetic moment, which can also separate multiple spare blades 21 within the receiving cavity 30. According to magnetic charge theory, adjacent spare blades 21 generate a repulsive force due to the proximity of like magnetic poles (NN or SS) (e.g., Figure 17 As shown), the laterally distributed magnetic elements 4 make the repulsive force dominant, that is, the repulsive force is greater than the metal adsorption force between the spare blades 21, thereby pushing the different spare blades 21 to separate from each other. This allows the user to directly pinch and remove one spare blade 21 when taking it out of the storage cavity 30. Furthermore, since this spare blade 21 is not attached to the others, it prevents the other spare blades 21 in the storage cavity 30 from being pulled off as well. It should also be noted that the magnetic elements 4 can be installed on all three second cavity walls 302, on two second cavity walls 302, or only on one second cavity wall 302; different numbers of magnetic elements 4 have different effects on the spare blades 21 in the storage cavity 30, for example, on the attached... Figure 3 In the structure shown, magnetic components 4 are installed on the three second cavity walls 302, so that a surrounding magnetic field is formed in the storage cavity 30. The spare blade 21 is affected by the magnetic field on both sides and the back, and the magnetic field coverage in the storage cavity 30 is more comprehensive. This generates a uniform repulsive force. When the magnetic poles are arranged in the same direction, the spare blade 21 is simultaneously subjected to the repulsive force on both sides and the back, forcing the spare blade 21 to move towards the center of the storage cavity 30, so as to achieve equal spacing separation. Moreover, when the shovel is tilted or vibrated, the surrounding magnetic field can provide multi-directional constraints to prevent the spare blades 21 from stacking or misaligning.

[0063] To achieve effective separation between different spare blades 21, in some embodiments, the dimension h of the magnetic element 4 is set to be greater than or equal to the dimension L of the receiving cavity 30 in the thickness direction of the spare blades 21, such as... Figure 5 and Figure 6As shown, in this embodiment, the dimension L is the minimum distance between the two first cavity walls 301, and the dimension h of the magnetic member 4 is equal to the dimension L of the storage cavity 30, so that the dimension h of the magnetic member 4 is similar to the total thickness H when multiple spare blades 21 are stacked in the storage cavity 30; if the dimension h of the magnetic member 4 is much smaller than the total thickness H, for example, when h / H is less than 0.5, the magnetic field cannot cover all the spare blades 21, resulting in the separation of the edge spare blades 21 and adhesion in the center, making it difficult to effectively separate the edge spare blades 21; if the dimension h of the magnetic member 4 is much larger than the total thickness H, for example, when h / H is greater than 1.5, the magnetic field diffuses excessively and the repulsive force decays, weakening the separation effect between multiple spare blades 21.

[0064] Refer Figure 8 and Figure 2 , in some embodiments, the magnetic member 4 can also be installed on the first cavity wall 301, and the magnetic members 4 are distributed on the two first cavity walls 301. At this time, the magnetic members 4 are distributed on the upper and lower surfaces of the spare blade 21, and the magnetic field direction of the magnetic member 4 vertically passes through the spare blade 21 to form a closed magnetic circuit. The spare blade 21 is adsorbed on the surface of the first cavity wall 301 by the magnetic member 4, and the magnetic member 4 plays a role in fixing the spare blade 21 in the storage cavity 30 to prevent the spare blade 21 from detaching from the storage cavity 30 through the opening 300.

[0065] In some embodiments, a receiving groove 303 can be opened on any one or more cavity walls, and the magnetic member 4 is installed in the receiving groove 303. The magnetic member 4 can be fixed in the receiving groove 303 by fixing methods such as potting glue bonding and interference fit. Specifically, the receiving groove 303 can be opened on the first cavity wall 301 or the second cavity wall 302 to achieve different effects; as Figure 12 shown, the receiving groove 303 is opened on the first cavity wall 301, and the notch of the receiving groove 303 faces the storage cavity 30 for facilitating the fixing of the magnetic member 4 in the receiving groove 303. The receiving groove 303 can be provided with one or two or three; again, as Figure 11 shown, the receiving groove 303 is opened on the second cavity wall 302, and the notch direction of the receiving groove 303 is the same as the direction of the opening 300 of the storage cavity 30; or as Figure 13 shown, the notch of the receiving groove 303 faces the inside of the storage cavity 30; or as Figure 14 shown, the notch of the receiving groove 303 faces the outside of the storage cavity 30; it is also possible to choose to distribute multiple magnetic members 4 on multiple first cavity walls 301 and multiple second cavity walls 302 at the same time. As Figure 15 shown, the receiving groove 303 is opened on four second cavity walls 302 and one first cavity wall 301 of the storage cavity 30, and the magnetic members 4 are correspondingly installed in each receiving groove 303; or as Figure 16As shown, the magnetic members 4 are distributed on three second chamber walls 302 and two first chamber walls 301 of the storage chamber 30; by mounting the magnetic members 4 on the chamber walls of the storage chamber 30, the magnetic members 4 are closer to the storage chamber 30, so as to improve the magnetic adsorption force of the magnetic members 4 on the spare blade 21.

[0066] Refer Figures 1-8 , in some embodiments, the housing 1 and the cartridge 3 are integrally formed. Specifically, the housing 1 further includes a connection end 11, and the connection end 11 is disposed opposite to the working end 10. In other words, the working end 10 is disposed at the head of the housing 1, and the connection end 11 is disposed at the tail of the housing 1, which conforms to the user's usage habit of the shovel; the cartridge 3 of this embodiment extends from the connection end 11. As Figure 2 shown, the housing 1 includes an upper housing 13 and a lower housing 14 that are snap-fitted to each other, and the cartridge 3 is formed by the tails of the upper housing 13 and the lower housing 14. After the upper housing 13 and the lower housing 14 are snap-fitted, a storage chamber 30 is formed at the connection end 11, and the opening 300 of the storage chamber 30 is distributed at the end of the housing 1 away from the working end 10. Specifically, groove structures can be provided at the tails of both the upper housing 13 and the lower housing 14. When the upper housing 13 and the lower housing 14 are snap-fitted, the two groove structures form the storage chamber 30; it should also be noted that both the upper housing 13 and the lower housing 14 are made of plastic material, so as to avoid interference from the housing 1 to the magnetic members 4 and ensure the stable magnetic force of the magnetic members 4 to adsorb the spare blade 21 in the storage chamber 30.

[0067] Refer Figures 4-8 , in some embodiments, the storage chamber 30 includes two first chamber walls 301 respectively formed on the upper housing 13 and the lower housing 14, and a plurality of second chamber walls 302 connecting the two first chamber walls 301. The number of the second chamber walls 302 can be specifically three, so that the cross-section of the storage chamber 30 is a quadrilateral, corresponding to the shape of the spare blade 21, which is beneficial to the storage of the spare blade 21 in the storage chamber 30; in addition, due to the disassembly and assembly structure of the upper housing 13 and the lower housing 14, therefore, the second chamber wall 302 includes a first side wall 3021 provided on the upper housing 13 and a second side wall 3022 provided on the lower housing 14. When the upper housing 13 and the lower housing 14 are snap-fitted, the second side wall 3021 and the second side wall 3022 are abutted and joined to form the second chamber wall 302.

[0068] Refer Figure 7 , in some embodiments, in order to install and fix the magnetic members 4 so that they can adsorb the spare blade 21 in the storage chamber 30, a receiving groove 303 can be provided on the upper housing 13 or the lower housing 14. As Figure 7As shown, the lower shell 14 is provided with a receiving groove 303 for installing magnetic components, and the receiving groove 303 is located on the outside of the second side wall 3022. The opening of the receiving groove 303 faces the upper shell 13. Before the upper shell 13 is fastened to the lower shell 14, the magnetic component 4 can be embedded in the receiving groove 303. After the upper shell 13 is fastened to the lower shell 14, the inner wall of the upper shell 13 restricts the movement of the magnetic component 4. Specifically, the magnetic component 4 is limited by the inner wall of the upper shell 13 abutting against the magnetic component 4, thereby improving the stability of the magnetic component 4 during use.

[0069] In some embodiments, particularly when the housing 3 and the shell 1 are integrally formed, to prevent the spare blade 21 from detaching from the storage cavity 30 through the opening 300, the scraper also includes a cover 5. The cover 5 is mounted on the housing 3 and is used to close or open the opening 300 to retrieve or place the spare blade 21. Figure 5 As shown, the opening 300 is distributed between the two first cavity walls 301 and the two second cavity walls 302. When the cover 5 closes the opening 300, the cover 5 simultaneously presses against the ends of the two first cavity walls 301 and the two second cavity walls 302, thereby closing the opening 300.

[0070] To facilitate operation of the cover 5 to open or close the opening 300, in this embodiment, the cover 5 includes a hinged end 50 and a snap-fit ​​end 51, such as... Figure 3 As shown, the hinge end 50 is hinged to the box body 3, and the snap-fit ​​end 51 can swing around the hinge end 50. Specifically, the snap-fit ​​end 51 can be configured as follows: Figure 3 and Figure 4 The L-shaped buckle shown has an L-shaped groove on the outer surface of the second cavity wall 302 that engages with the L-shaped buckle. In use, by applying a force away from the working end 10 to the locking end 51, the locking end 51 can be disengaged from the L-shaped groove, thereby opening the opening 300 to facilitate the user to access the spare blade 21.

[0071] like Figure 3 As shown, the box body 3 has an operating notch 31 at the opening 300, and the operating notch 31 is recessed towards the working end 10; the cover 5 includes a protrusion 52 that mates with the operating notch 31. After the cover 5 is opened, part of the structure of the spare blade 21 can be exposed through the operating notch 31 for easy access by the user. The corresponding protrusion 52 on the cover 5 ensures that the spare blade 21 is not exposed after the cover 5 closes the opening 300, making the overall structure of the shovel more compact.

[0072] In some embodiments, the box body 3 has a drawer-type structure, that is, the box body 3 and the shell 1 are assembled separately, such as... Figure 9 , Figure 10 and Figure 11As shown, the housing 1 has a connecting cavity 12, and the box 3 can be movably accommodated within the connecting cavity 12. Specifically, the box 3 and the connecting cavity 12 can be connected in a sliding or rotating manner. For example, one end of the box 3 can be hinged to the connecting cavity 12, allowing the box 3 to rotate into or out of the connecting cavity 12. In this embodiment, the box 3 and the connecting cavity 12 are slidably connected, meaning the box 3 can be inserted into or pulled out of the connecting cavity 12. Under this slidable connection, the opening 300 can be formed at, for example... Figure 11 At the first cavity wall 301 shown, the surface of the spare blade 21 can be directly seen through the opening 300. Furthermore, when creating the opening 300, it is necessary to ensure that the opening 300 faces the side of the shovel with the operating buttons, to conform to the user's usage habits. That is, after pulling the box 3 out of the connecting cavity 12, the opening 300 should be horizontally upward, so that the spare blade 21 inside the storage cavity 30 will not detach from the storage cavity 30 due to gravity. Figure 11 As shown, in some embodiments, the receiving groove 303 is formed on the second cavity wall 302, and the magnetic element 4 is installed on the second cavity wall 302, so that the magnetic element 4 can both fix the spare blade 21 in the storage cavity 30 and allow different spare blades 21 to be separated from each other, so as to facilitate the user to take them out through the opening 300. In addition, the groove opening of the receiving groove 303 is oriented in the same direction as the opening 300 of the storage cavity 30, which is conducive to installing and fixing the magnetic element 4 in the receiving groove 303. Furthermore, in the thickness direction of the spare blade 21, the size of the receiving groove 303, the size of the storage cavity 30, and the size of the magnetic element 4 are approximately the same, so that the magnetic field of the magnetic element 4 can fully cover the spare blade 21 in the storage cavity 30.

[0073] To facilitate inserting or pulling the housing 3 into or out of the connecting cavity 12, the scraper also includes a handle 6, such as... Figure 10 and Figure 11 As shown, the handheld part 6 is connected to the box body 3. After the box body 3 is inserted into the connecting cavity 12, the handheld part 6 is outside the connecting cavity 12. Specifically, a limiting wall 60 can be opened on the side where the handheld part 6 is connected to the box body 3, so that after the box body 3 is inserted into the connecting cavity 12, the limiting wall 60 abuts against the end of the shell 1, thereby limiting the handheld part 6.

[0074] like Figure 11 As shown, an anti-slip structure 61, such as anti-slip texture or anti-slip bumps, can also be provided on the surface of the handheld component 6 to improve the friction of the surface of the handheld component 6 and make it easier for the user to operate the handheld component 6.
