Technical Field
[0001] This utility model relates to a blender, and more particularly to a blender with a quick-release blade structure. Background Technology
[0002] A high-speed blender is a kitchen appliance that integrates multiple functions such as juicing, blending, grinding, and ice crushing. It mainly consists of a casing and a blade assembly. The blade assembly includes a connecting column, a connecting plate, and blades. The casing has a blending chamber with an assembly hole at the bottom for inserting the connecting column. The upper end of the connecting column abuts against the bottom of the blending chamber, while the lower end extends out of the blending chamber and is threadedly connected to the connecting plate. The connecting column and connecting plate cooperate to fix the blade assembly to the casing. The blades are mounted on the connecting column and can rotate relative to it. Existing high-speed blenders configure the blade assembly as a connecting column, connecting plate, and blades. The connecting column is inserted into the casing with its upper end abutting against the bottom of the blending chamber, and its lower end extends out of the blending chamber and is threadedly connected to the connecting plate, thus locking the blade assembly to the casing. This method results in numerous components, complex connections, and the connecting column is prone to loosening when the blades rotate at high speed. Utility Model Content
[0003] The purpose of this utility model is to provide a blender with a quick-release blade structure to solve the problem of existing blenders where the blade assembly is configured as a connecting column, a connecting plate and a blade, the connecting column is inserted into the outer shell and its upper end abuts against the bottom of the blending chamber, and the lower end extends out of the blending chamber and is threadedly connected to the connecting plate, resulting in a blade assembly with many parts and complex connections.
[0004] This utility model is achieved through the following technical solution:
[0005] A blender with a quick-release blade structure includes a housing and a blade assembly. The housing has an upward-opening blending chamber with an assembly hole at the bottom. The assembly hole has an upper stop block on its wall and an insertion hole on its lower side. The blade assembly includes a connecting post and a blade. The connecting post has an upper abutment ring and a lower stop block spaced apart vertically on its periphery. The lower stop block has an insertion block on its upper side. The connecting post can be inserted into the insertion hole from top to bottom and rotate relative to the housing, causing the lower stop block to abut against the lower side of the upper stop block and the insertion block to be inserted into the insertion hole. When the lower stop block abuts against the lower side of the upper stop block, the upper abutment ring is located above the bottom of the blending chamber and cooperates with the lower stop block to restrict the vertical movement of the connecting post. The blade is mounted on the connecting post and can rotate relative to the connecting post.
[0006] Furthermore, the upper abutment extends circumferentially around the connecting column, and a sealing ring passing through the connecting column is provided between the upper abutment ring and the bottom of the wall-breaking cavity.
[0007] Furthermore, there are several upper stop blocks and several lower stop blocks, each corresponding to one other. Several upper stop blocks are spaced apart in the circumferential direction of the assembly hole to form several guide grooves. When the connecting post is inserted into the insertion hole, the lower stop block is offset from the upper stop block and moves along the guide groove.
[0008] Furthermore, the lower end sidewall of the upper stop block is provided with two upper inclined shoulders, which are arranged opposite each other in the circumferential direction of the mounting hole. In the two upper inclined shoulders, either upper inclined shoulder is inclined from bottom to top in a direction away from the other upper inclined shoulder. The upper end sidewall of the lower stop block is provided with two lower inclined shoulders, which are arranged opposite each other in the circumferential direction of the connecting column. In the two lower inclined shoulders, either lower inclined shoulder is inclined from top to bottom in a direction away from the other lower inclined shoulder.
[0009] Furthermore, the wall of the insertion hole is formed with two guide slopes, which are arranged opposite to each other in the circumferential direction of the assembly hole. In the direction towards the other guide slope, either guide slope is inclined upward from the lower edge of the insertion hole, and the insertion block is narrower at the top and wider at the bottom.
[0010] Furthermore, the upper stop block is integrally formed with the outer shell, and the lower stop block is integrally formed with the connecting post.
[0011] Furthermore, the cutting tool includes a connecting rod, a cutting head, and a transmission head. The connecting post has a connecting hole coaxially arranged therewith for the connecting rod to be inserted. One end of the connecting rod extends into the wall-breaking cavity and connects to the cutting head, while the other end extends out from the lower side of the connecting post and connects to the transmission head.
[0012] Furthermore, a ball bearing is provided on the connecting rod and housed within the connecting column.
[0013] The advantages of this technical solution are that by configuring an upper stop block on the wall of the assembly hole, configuring an insertion hole on the lower side of the upper stop block, configuring an upper abutment ring and a lower stop block on the outside of the connecting column, and configuring an insertion block on the upper side of the lower stop block, the connecting column can be inserted into the insertion hole from top to bottom and rotate relative to the outer shell, so that the lower stop block abuts against the lower side of the upper stop block and the insertion block is inserted into the insertion hole. The insertion block into the insertion hole restricts the circumferential rotation of the connecting column, and the lower stop block cooperates with the upper abutment ring to restrict the vertical movement of the connecting column. This simplifies the number of parts and assembly steps of the tool assembly. At the same time, the connecting column is locked in the circumferential and vertical directions, so that the connection between the connecting column and the outer shell is stable and not easy to loosen when the tool rotates at high speed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Figure 1-8As shown, the blender with a quick-release blade structure includes a housing 1 and a blade assembly 2. The housing 1 has an upward-opening blending cavity 101. The bottom of the blending cavity 101 is provided with an assembly hole 102. The wall of the assembly hole 102 is provided with an upper stop block 103. The lower side of the upper stop block 103 is provided with an insertion hole 104. The blade assembly 2 includes a connecting post 201 and a blade 202. The periphery of the connecting post 201 is provided with an upper abutment ring 203 and a lower stop block 204 arranged at intervals. The lower stop block 204 has an upper abutment ring 203 and a lower stop block 204. A plug 205 is provided on the side, and the connecting post 201 can be inserted into the socket 104 from top to bottom and rotate relative to the outer shell 1, so that the lower stop block 204 abuts against the lower side of the upper stop block 103 and the plug 205 is inserted into the socket 104. When the lower stop block 204 abuts against the lower side of the upper stop block 103, the upper abutment ring 203 is located above the bottom of the wall breaking chamber 101 and cooperates with the lower stop block 204 to restrict the vertical movement of the connecting post 201. The cutter 202 is provided on the connecting post 201 and can rotate relative to the connecting post 201. When the connecting post 201 is inserted into the socket 104 from top to bottom, the lower stop block 204 and the upper stop block 103 are offset circumferentially from each other in the assembly hole 102. When the lower stop block 204 moves below the upper stop block 103, the connecting post 201 is rotated so that the lower stop block 204 abuts against the lower side of the upper stop block 103 and the insert block 205 is inserted into the socket 104. The insert block 205 is inserted into the socket 104 to restrict the circumferential rotation of the connecting post 201. When the lower stop block 204 abuts against the lower side of the upper stop block 103, the upper abutment ring 203 cooperates with the lower stop block 204 to restrict the vertical movement of the connecting post 201. Therefore, the connecting post 201 is locked on the outer shell 1.
[0026] In summary, this embodiment provides a blender with a quick-release blade structure to solve the problem of existing blenders where the blade assembly is configured as a connecting post, a connecting plate, and a blade. The connecting post is inserted into the outer shell with its upper end abutting the bottom of the blending chamber, and its lower end extends out of the blending chamber and is threadedly connected to the connecting plate. This results in numerous blade assembly components and complex connections. The solution mainly involves configuring an upper stop block 103 on the wall of the assembly hole 102, configuring an insertion hole 104 on the lower side of the upper stop block 103, configuring an upper abutment ring 203 and a lower stop block 204 on the outside of the connecting post 201, and configuring an insertion block 20 on the upper side of the lower stop block 204. 5. The connecting post 201 can be inserted into the socket 104 from top to bottom and rotate relative to the outer shell 1, so that the lower stop block 204 abuts against the lower side of the upper stop block 103 and the insert block 205 is inserted into the socket 104. The insertion block 205 into the socket 104 restricts the circumferential rotation of the connecting post 201. The lower stop block 204 cooperates with the upper abutment ring 203 to restrict the vertical movement of the connecting post 201, simplifying the number of accessories and assembly steps of the tool assembly 2. At the same time, the connecting post 201 is locked in the circumferential and vertical directions, so that the connection between the connecting post 201 and the outer shell 1 is stable and not easy to loosen when the tool 202 rotates at high speed.
[0027] In this embodiment of the invention, the upper abutment ring 203 extends circumferentially around the connecting post 201, and a sealing ring 3 passing through the connecting post 201 is provided between the upper abutment ring 203 and the bottom of the breaking cavity 101. This arrangement, by placing the sealing ring 3 passing through the connecting post 201 between the upper abutment ring 203 and the bottom of the breaking cavity 101, effectively fills the gap between the upper abutment ring 203 and the bottom of the breaking cavity 101, ensuring a stable connection between the connecting post 201 and the outer shell 1, and preventing it from easily loosening or shaking when the cutter 202 rotates at high speed.
[0028] In this embodiment of the invention, there are multiple upper stop blocks 103 and lower stop blocks 204, each corresponding to the other. The upper stop blocks 103 are spaced apart in the circumferential direction of the assembly hole 102 to form multiple guide grooves 105. When the connecting post 201 is inserted into the insertion hole 104, the lower stop blocks 204 are offset from the upper stop blocks 103 and move downwards along the guide grooves 105. This arrangement, by configuring multiple upper stop blocks 103 and lower stop blocks 204, ensures a stable connection between the connecting post 201 and the outer shell 1, and prevents the connecting post 201 from easily loosening or shaking when the cutter 202 rotates at high speed.
[0029] In this embodiment of the invention, the lower end sidewall of the upper stop block 103 is provided with two upper inclined shoulders 106, which are arranged opposite each other in the circumferential direction of the mounting hole 102. Either upper inclined shoulder 106 is inclined upwards in a direction away from the other. The upper end sidewall of the lower stop block 204 is provided with two lower inclined shoulders 206, which are arranged opposite each other in the circumferential direction of the connecting column 201. Either lower inclined shoulder 206 is inclined downwards in a direction away from the other. This arrangement, by providing upper inclined shoulders 106 on the upper stop block 103 and lower inclined shoulders 206 on the lower stop block 204, facilitates the rotation of the lower stop block 204 to below the upper stop block 103, improving operational convenience.
[0030] In this embodiment of the invention, the wall of the insertion hole 104 is formed with two guide slopes 107. The two guide slopes 107 are arranged opposite each other in the circumferential direction of the assembly hole 102. Either guide slope 107 is inclined upwards from the lower edge of the insertion hole 104 in the direction towards the other guide slope 107. The insertion block 205 is narrower at the top and wider at the bottom. This arrangement, by configuring the guide slopes 107 on the wall of the insertion hole 104 and configuring the insertion block 205 to be narrower at the top and wider at the bottom, facilitates the insertion of the insertion block 205 into the insertion hole 104, improving operational convenience.
[0031] In this embodiment of the invention, the upper stop block 103 is integrally formed with the outer shell 1, and the lower stop block 204 is integrally formed with the connecting post 201. This arrangement, by configuring the upper stop block 103 to be integrally formed with the outer shell 1 and the lower stop block 204 to be integrally formed with the connecting post 201, ensures a stable connection between the connecting post 201 and the outer shell 1.
[0032] In this embodiment of the invention, the cutter 202 includes a connecting rod 207, a cutting head 208, and a transmission head 209. The connecting post 201 has a connecting hole 210 coaxially arranged therewith, into which the connecting rod 207 is inserted. One end of the connecting rod 207 extends into the breaking chamber 101 and connects to the cutting head 208, while the other end extends out from the lower side of the connecting post 201 and connects to the transmission head 209. The transmission head 209 is connected to a motor. This configuration, by arranging the cutter 202 as a connecting rod 207, a cutting head 208, and a transmission head 209, with one end of the connecting rod 207 extending into the breaking chamber 101 and connecting to the cutting head 208, and the other end extending out from the lower side of the connecting post 201 and connecting to the transmission head 209, makes the connection between the cutter 202 and the connecting post 201 compact and reasonable.
[0033] In this embodiment of the invention, a ball bearing 211, which is housed within a connecting post 201, passes through the connecting rod 207. This arrangement, by configuring the ball bearing 211 within the connecting post 201 on the connecting rod 207, ensures smooth rotation of the connecting rod 207.
