[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The blade assembly rotates axially to crush the food, and the position of the blade assembly in the outer shell is adjusted by the telescopic mechanism to adjust the insertion depth of the blade assembly in the food, thereby increasing the contact area between the blade assembly and the food, optimizing the crushing effect and improving processing efficiency.

[0022] 2. During use, the user can hold the outer shell with one hand and apply pressure to the telescopic mechanism with the other hand. This will drive the blade assembly to move axially relative to the outer shell, thereby achieving precise adjustment of the blade assembly's extension and retraction. This prevents the blade assembly from extending too far and hitting the container containing food, thus protecting the crushing device. Furthermore, the outer diameter of the handle of the outer shell gradually increases along the axial direction, making it easier for the user to grip the outer shell and control the extension and retraction of the blade assembly more easily during operation, reducing the user's control effort and optimizing the user experience.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0035] like Figure 1 As shown in Figure 8, this utility model provides a telescopic crushing device, which includes a crushing mechanism 1, a housing assembly 2, and a telescopic mechanism 3. The crushing mechanism 1 includes an axially rotatable cutter head assembly 11, which crushes food by rotating axially. The housing assembly 2 is located on the outer periphery of the cutter head assembly 11. The telescopic mechanism 3 is located between the cutter head assembly 11 and the housing assembly 2. The telescopic mechanism 3 is used to drive the cutter head assembly 11 to move axially and telescopically relative to the housing assembly 2. The housing assembly 2 has a space for the cutter head assembly 11 to move telescopically. The position of the cutter head assembly 11 in the housing assembly 2 is adjusted by the telescopic mechanism 3 to adjust the insertion depth of the cutter head assembly 11 in the food, thereby increasing the contact area between the cutter head assembly 11 and the food, optimizing the crushing effect, and improving processing efficiency.

[0036] In this embodiment, the telescopic crushing device can be applied to a handheld grinder. The telescopic crushing device is connected to the handheld main unit to obtain the power for the axial rotation of the cutter head assembly 11. In actual use, the user can directly press the telescopic mechanism 3, which drives the cutter head assembly 11 to move up and down relative to the outer shell assembly 2, thereby adjusting the contact area between the cutter head assembly 11 and the food. Simultaneously, the cutter head assembly 11 can rotate axially within the outer shell assembly 2 to achieve the crushing process of the food. Furthermore, to improve the user's control precision over the telescopic movement of the cutter head assembly 11, the outer shell assembly 2 includes an outer shell 21, which includes a handheld part 211. The outer diameter of the handle 211 gradually increases along the axial direction, allowing the user to control the handheld main unit with one hand and grip the outer shell 21 with the other hand via the handle 211. During use, the user can hold the outer shell 21 with one hand while applying pressure to the telescopic mechanism 3 via the handheld main unit. This telescopic mechanism 3 drives the blade assembly 11 to move axially relative to the outer shell 21, enabling precise adjustment of the blade assembly 11's extension and retraction. This prevents the blade assembly 11 from extending too far and impacting the container containing food, thus protecting the crushing device. Furthermore, the gradually increasing outer diameter of the handle 211 allows for a better grip on the outer shell 21, making it easier for the user to control the extension and retraction of the blade assembly 11, reducing the user's control effort and optimizing the user experience.

[0037] Optionally, in some embodiments, the outer diameter of the handle 211 gradually increases axially from its top to its bottom; in other embodiments, the outer diameter of the handle 211 gradually increases axially from its bottom to its top. Further optionally, to reduce the production cost of the housing 21, the housing 21 is designed as a hollow shell, which also facilitates the telescopic movement of the telescopic mechanism 3 and the cutter head assembly 11 within the housing 21.

[0038] Specifically, such as Figure 1As shown in Figure 7, the outer casing assembly 2 further includes a scratch-resistant cover 22, which is connected to the lower part of the outer casing 21. The outer casing 21 also includes a first connecting portion 212 and a second connecting portion 213 respectively disposed on both sides of the handheld part 211. The first connecting portion 212 is used to connect with the telescopic mechanism 3, and the second connecting portion 213 is used to connect with the scratch-resistant cover 22. The blade assembly 11 includes a blade shaft 111 and a blade head 112 arranged vertically. The blade shaft 111 and the blade head 112 can be a separate structure or an integrated structure. The blade head 112 is placed inside the scratch-resistant cover 22, and the blade shaft 111 extends upward into the outer casing 21, with the top of the blade shaft 111 extending through the outer casing 21 and connecting to the power mechanism of the handheld host. The telescopic mechanism 3 includes a telescopic drive component 31, a connecting cylinder 32, and a reset component 33. The telescopic drive component 31 is slidably connected to the outer shell 21 via the first connecting part 212. The connecting cylinder 32 is fixedly connected to the telescopic drive component 31 and is sleeved on the outer periphery of the cutter shaft 111. The cutter shaft 111 is axially rotatably inserted into the connecting cylinder 32 via the connecting component 34, and the connecting component 34 can restrict the axial telescopic movement of the cutter shaft 111 relative to the connecting cylinder 32. The connecting cylinder 32 is slidably inserted between the outer shell 21 and the anti-scratch cover 22, that is, the outer shell 21 and the anti-scratch cover 22 have a space for the telescopic movement of the connecting cylinder 32. The reset component is disposed between the connecting cylinder 32 and the anti-scratch cover 22.

[0039] In use, the telescopic drive member 31 can move downward relative to the outer shell 21 under pressure, thereby driving the connecting cylinder 32 to move downward synchronously relative to the outer shell 21 and the anti-scratch cover 22. The connecting cylinder 32 then drives the cutter shaft 111 to move downward synchronously, which in turn drives the cutter head 112 to move downward relative to the anti-scratch cover 22, increasing the insertion depth of the cutter head 112 into the food, thus increasing the crushing and processing area between the cutter head 112 and the food. The anti-scratch cover 22 abuts against the container containing the food, limiting the downward movement of the outer shell 21 under pressure, thereby ensuring the downward movement of the cutter head assembly 11. During the crushing process, the cutter head 112 remains within the anti-scratch cover 22 and rotates axially. To achieve the crushing and processing of food ingredients, the anti-scratching cover 22 has an opening for the crushed food ingredients to pass through. The anti-scratching cover 22 prevents the crushed food ingredients from splashing out to a certain extent, and also separates the cutter head 112 from the outside environment, avoiding injury to personnel due to accidental rotation of the cutter head 112. In addition, the connecting assembly 34 enables the axial rotation of the cutter shaft 111 within the connecting cylinder 32 and restricts the axial extension and retraction of the cutter shaft 111 relative to the connecting cylinder 32. This ensures that the extension and retraction of the cutter head assembly 11 is precisely controlled by the extension and retraction mechanism 3, preventing the cutter shaft 111 from shifting due to axial movement within the connecting cylinder 32 under high-speed rotation, thereby enhancing the stability of the cutter head assembly 11. After the food ingredients are crushed, the connecting cylinder 32 can be automatically moved upward and reset by the reset component 33, and the blade assembly 11 can be moved upward and reset by the connecting component 34, so as to reduce the user's operating difficulty and optimize the user experience. The reset component 33 has a certain pre-tightening force on the connecting cylinder 32 to ensure that the telescopic drive component 31 is subjected to sufficient pressing force to drive the connecting cylinder 32 downward and realize the downward movement of the blade assembly 11, making the crushing device safer and more reliable.

[0040] Optionally, in some embodiments, such as Figure 5As shown, the telescopic drive member 31 is provided with a mating part 311 corresponding to the first connecting part 212. The first connecting part 212 is slidably connected to the mating part 311. The first connecting part 212 is vertically arranged on the upper part of the handheld part 211. Optionally, the first connecting part 212 or the mating part 311 is a groove that extends circumferentially. Correspondingly, another connecting structure is a cylindrical slider that matches the groove. The structure is simple and easy to implement. Furthermore, in order to improve the sliding stability of the telescopic drive member 31 relative to the outer shell 21, the outer diameter of the handheld part 211 gradually increases axially from the second connecting part 213 toward the first connecting part 212. The handheld part 211 and the first connecting part 212 have a preset angle 210. The connection between the second connecting part 213 and the handheld part 211 is smoothly transitioned. The handheld part 211 is preferably a conical handheld part 211 to improve the user's comfort in gripping the outer shell 21. Optionally, in other embodiments, the outer casing 21 is a one-piece molded structure to enhance the structural strength of the outer casing 21 and extend its service life.

[0041] Optionally, in some embodiments, such as Figure 7 As shown, the connecting cylinder 32 has a first limiting portion 321 on its outer periphery, and a second limiting portion 322 on its outer periphery. Optionally, the first limiting portion 321 extends circumferentially along the connecting cylinder 32, that is, the first limiting portion 321 can be configured as an annular limiting portion located on the outer periphery of the connecting cylinder 32. The second limiting portion 322 extends radially outward from the first limiting portion 321 along the connecting cylinder 32. The outer shell 21 also includes a third limiting portion 214 disposed between the handle portion 211 and the second connecting portion 213. The third limiting portion 214 at least partially corresponds to the upper part of the second limiting portion 322. The third limiting portion 214 has a first through hole 215 for the connecting cylinder 32 to pass through. 2. Optionally, the third limiting part 214 can be configured as an annular limiting part located on the inner wall of the outer shell 21; the top of the anti-scratch cover 22 is provided with an upwardly extending first mounting cylinder 221, the first mounting cylinder 221 extends into the second connecting part 213, the peripheral wall of the first mounting cylinder 221 is provided with a limiting groove 222 corresponding to the second limiting part 322, the limiting groove 222 is used to limit the downward movement distance of the connecting cylinder 32, and a first buffer washer 4 is provided between the third limiting part 214 and the first mounting cylinder 221; the reset assembly 33 includes an elastic element 331, the elastic element 331 is disposed between the first limiting part 321 and the first mounting cylinder 221, and is sleeved on the outside of the connecting cylinder 32.

[0042] When the telescopic drive member 31 is pressed, causing the connecting cylinder 32 to move downward, the connecting cylinder 32 applies a downward squeezing force to the elastic member 331 through the first limiting part 321, allowing the elastic member 331 to accumulate elastic energy to drive the connecting cylinder 32 to move upward and reset. Simultaneously, the connecting cylinder 32, through the first limiting part 321, drives the second limiting part 322 to move downward along the limiting groove 222. At this time, the bottom wall of the limiting groove 222 limits the downward movement distance of the second limiting part 322, thereby limiting the downward movement distance of the connecting cylinder 32 to prevent the cutter head 112 from moving too far downward relative to the protective cover and impacting it. A container containing food protects the blade assembly 11. When the connecting cylinder 32 moves upward and resets under the elastic force of the elastic member 331, the second limiting part 322 moves upward along the limiting groove 222 via the connecting cylinder 32. At this time, the upward reset distance of the connecting cylinder 32 is limited by the third limiting part 214. This helps to improve the telescopic efficiency of the telescopic mechanism 3 and ensures the effective operation of the telescopic mechanism 3. Preferably, the third limiting part 214 extends radially inward along the outer shell 21 so that the third limiting part 214 corresponds to the upper part of the first limiting part 321, thereby improving the limiting effect of the third limiting part 214. In addition, by setting the first buffer washer 4 between the third limiting part 214 and the first mounting cylinder 221, the impact force on the third limiting part 214 when the connecting cylinder 32 moves upward and resets is reduced, which helps to reduce noise and vibration and further protect the crushing device.

[0043] Optionally, in some embodiments, such as Figure 6As shown, a buffer connecting sleeve 5 is provided inside the first mounting cylinder 221. The buffer connecting sleeve 5 is fitted inside the first mounting cylinder 221. The connecting cylinder 32 is slidably inserted into the buffer connecting sleeve 5. The outer wall of the connecting cylinder 32 contacts the inner wall of the buffer connecting sleeve 5 to improve the stability of the connecting cylinder 32. However, the connecting cylinder 32 can still move up and down inside the buffer connecting sleeve 5 under external force. A third connecting part 51 is provided on the outer periphery of the buffer connecting sleeve 5, which is fitted into the first mounting cylinder 221. The reset assembly 33 also includes a first positioning member 332 sleeved on the outside of the buffer connecting sleeve 5. The first positioning member 332 and the first... The three connecting parts 51 are connected in a cooperative manner. Optionally, the third connecting part 51 is provided with an upward-facing mounting groove 52, and the first positioning member 332 is provided in the mounting groove 52. The first positioning member 332 is provided with a positioning groove 333 that is adapted to the elastic member 331. The elastic member 331 abuts between the first limiting part 321 and the positioning groove 333. The installation position of the elastic member 331 is positioned by the positioning groove 333, which helps to enhance the connection stability of the elastic member 331. The elastic member 331 is sleeved on the outside of the buffer connecting sleeve 5 to further enhance the stability of the elastic member 331, thereby improving the reliability of the telescopic mechanism 3.

[0044] Optionally, in some embodiments, such as Figure 6 As shown, a retaining ring 223 is sleeved on the outer periphery of the first mounting cylinder 221. The retaining ring 223 has a latching part 224 that is engaged with the limiting groove 222. The latching part 224 is engaged in the limiting groove 222 and is opposite to the second limiting part 322. When the connecting cylinder 32 moves the second limiting part 322 downward, the latching part 224 limits the downward movement distance of the second limiting part 322 in the limiting groove 222, so as to avoid the blade head 112 moving too far downward relative to the protective cover and hitting the container containing food, thus protecting the blade head assembly 11. It also helps to reduce the processing difficulty of the limiting groove 222. The retaining ring 223 can be used to make up for the defect of insufficient precision of the limiting groove 222 during the production process, thereby improving the finished product quality of the crushing device.

[0045] Optionally, in some embodiments, such as Figure 6As shown, the bottom of the connecting cylinder 32 is provided with a second through hole 323 for the cutter shaft 111 to pass through. The connecting assembly 34 includes a vibration damper 341, a sealing member 342, and a receiving member 343. The vibration damper 341 and the sealing member 342 are arranged vertically inside the connecting cylinder 32. The bottom of the connecting cylinder 32 supports the sealing member 342 and the vibration damper 341. The sealing member 342 contacts the cutter shaft 111 to close the second through hole 323, thereby connecting the inner cavity of the connecting cylinder 32 with the anti-scratch device. The inner space of the cover 22 is separated to prevent the lubricating oil inside the connecting cylinder 32 from leaking and to block external impurities from entering the connecting cylinder 32. In particular, it prevents food from entering the connecting cylinder 32 through the second through hole 323 and affecting the axial rotation of the cutter shaft 111, and keeps the cutter shaft 111 and the receiving part 343 clean, reducing wear and extending the service life of the cutter shaft 111. The vibration damping part 341 is axially rotatably disposed inside the connecting cylinder 32 to ensure the axial rotation of the cutter shaft 111 and to dampen vibration. Component 341 can absorb and reduce the vibration generated by the cutter shaft 111 during high-speed rotation, reduce noise, and improve the stability and comfort of equipment operation; the receiving component 343 is disposed between the anti-vibration component 341 and the cutter shaft 111, and a second positioning component 113 is fixed on the outer periphery of the cutter shaft 111. The second positioning component 113 is located above the receiving component 343, and the anti-vibration component 341 is located below the receiving component 343. The second positioning component 113 and the anti-vibration component 341 clamp the cutter shaft 111 from the upper and lower sides respectively. The receiving member 343 is tightly fixed to restrict the axial telescopic movement of the cutter shaft 111 relative to the anti-vibration member 341. This ensures that the telescopic movement of the cutter head assembly 11 is precisely controlled by the telescopic mechanism 3, preventing the cutter shaft 111 from shifting due to axial movement within the connecting cylinder 32 under high-speed rotation. This enhances the stability of the cutter head assembly 11, and the receiving member 343 reduces the friction force when the cutter shaft 111 rotates axially, improving the efficiency of food crushing and processing.

[0046] Optionally, in some embodiments, such as Figure 2 , 6As shown, the top of the scratch-resistant cover 22 is also provided with a fourth connecting part 225 located on the outer periphery of the first mounting cylinder 221, and a fifth connecting part 216 is provided inside the second connecting part 213. The fourth connecting part 225 and the fifth connecting part 216 are connected to each other so that the scratch-resistant cover 22 is connected to the second connecting part 213; thereby realizing the quick assembly between the scratch-resistant cover 22 and the outer shell 21. Further optionally, the fourth connecting part 225 can be provided as an outward hook, and the fifth connecting part 216 can be provided as a positioning block corresponding to the hook. The hook is hooked onto the upper part of the positioning block so that the scratch-resistant cover 22 is connected to the outer shell 21. In addition, a second buffer washer 6 is provided between the fourth connecting part 225 and the anti-scratch cover 22. The second buffer washer 6 can be made of elastic material such as rubber ring to absorb the vibration generated when the crushing device crushes the food, thereby reducing vibration and noise. The second buffer washer 6 has a pre-tightening force, which helps to enhance the connection stability between the anti-scratch cover 22 and the outer shell 21.

[0047] Optionally, in other embodiments, the anti-reverse ring 223 is connected between the first mounting cylinder 221 and the fifth connecting part 216, and the snap-fit ​​part 224 of the anti-reverse ring 223 is correspondingly snapped into the limiting groove 222, so as to enhance the connection stability of the anti-reverse ring 223.

[0048] Optionally, in some embodiments, such as Figure 5 , 7As shown in Figure 8, the top of the connecting cylinder 32 is provided with an extension piece 324, which extends upward along the axial direction. The telescopic drive member 31 is provided with a second mounting cylinder 312. The second mounting cylinder 312 has a third through hole 313 for the cutter shaft 111 to pass through, a connecting groove 314 corresponding to the extension piece 324, and a top block 315 located outside the connecting groove 314. During assembly, the extension piece 324 can extend into the connecting groove 314 and be fixed between the top block 315 and the inner wall of the connecting groove 314. The connecting cylinder 32 is fixedly connected to the telescopic drive member 31; when the telescopic drive member 31 is pressed down relative to the outer shell 21, the extension piece 324 is clamped and fixed in the connecting groove 314 by the top block 315, so as to increase the static friction between the extension piece 324 and the second mounting cylinder 312, and prevent the top block 315 from being pressed down relative to the extension piece 324, thereby realizing the downward movement of the connecting cylinder 32 by the telescopic drive member 31; and as the usage time of the crushing device is extended, Wear on the top block 315 reduces the static friction between the extension piece 324 and the second mounting cylinder 312, causing relative movement between the second mounting cylinder 312 and the extension piece 324 when the telescopic drive member 31 is pressed. To ensure the normal operation of the telescopic mechanism 3, a third positioning member 114 is fixed on the outer periphery of the cutter shaft 111. The third positioning member 114 is opposite to the bottom of the second mounting cylinder 312. When the telescopic drive member 31 is pressed, it moves downward relative to the outer shell 21, and the second mounting cylinder... When the second mounting cylinder 312 moves downward relative to the extension piece 324 through the connecting groove 314, it moves to abut against the third positioning member 114 and generates a downward pushing force on the third positioning member 114. This causes the cutter shaft 111 to move downward through the third positioning member 114. The downward movement of the cutter shaft 111 and the connecting cylinder 32 are driven downward through the connecting assembly 34. The downward movement of the connecting cylinder 32 can compress the elastic member 331 through the first limiting part 321, thereby realizing the normal operation of the telescopic mechanism 3.

[0049] Optionally, in some embodiments, such as Figure 4 As shown, the crushing mechanism 1 also includes a rotary drive 12, which is located on the top of the cutter shaft 111 and is used to connect with an external power mechanism. The external power mechanism can be a handheld host. The rotary drive 12 transmits the kinetic energy of the external power mechanism to the cutter shaft 111 to realize the axial rotation of the cutter head assembly 11.

[0050] In other embodiments, the cutter shaft 111 may pass through the third through hole 313 into the second mounting cylinder 312 and be connected to the rotary drive member 12. The second mounting cylinder 312 has a cavity communicating with the third through hole 313, and the cavity can accommodate the rotary drive member 12.

[0051] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
