[0034] The terms "first" and "second" used in the terminology of this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as limiting the order of events.

[0035] The present invention provides a handheld stirring mechanism with a self-locking function, comprising a housing 11, a starting device 13 located on one side of the housing 11, and an unlocking device 12 located on one side of the housing 11 and opposite to the starting device 13. A fixing frame 111 is disposed inside the housing 11. The starting device 13 includes a micro switch 131 located on the fixing frame 111 and a start button 132 located on one side of the micro switch 131 and extending to the outside of the housing 11. The unlocking device 12 includes a movable component on the fixing frame 111 and located between the micro switch 131 and the start button. The lock lever 122 between the buttons 132, the push rod 121 connected to the fixing frame 111 and used to push the lock lever 122 to move, the first return spring 123 located at one end of the lock lever 122, and the second return spring 124 located at one end of the push rod 121, the lock lever 122 is provided with a switch hole 1221, the push rod 121 is provided with a protruding buckle 1211, and the fixing frame 111 is provided with a positioning block 1111. When the push rod 121 pushes the lock lever 122, the start button 132 and the switch hole 1221 are positioned opposite each other.

[0036] The mounting bracket 111 is installed inside the housing 11. The starting device 13 is used to start the handheld stirring mechanism. The unlocking device 12 is used to self-lock the starting device 13 and unlock the starting device 13 to prevent accidental pressing of the starting device 13. The mounting bracket 111 is used to fix the micro switch 131, the locking rod 122, and the push rod 121. The locking rod 122 is used to block the start button 132 from moving down to prevent the start button 132 from moving down and accidentally pressing the micro switch 131. The push rod 121 is used to push the locking rod 122 so that the switch hole 1221 on the locking rod 122 engages with the start button 122. The positions of the start buttons 132 and 124 are opposite to each other, facilitating the pressing of the start button 132 to press the micro switch 131. The first return spring 123 is used to reset the locking lever 122 to prevent the start button 132 from pressing the micro switch 131. The second return spring 124 is used to reset the push lever 121, facilitating the next push of the locking lever 122. When the hand-held stirring mechanism is in the self-locking state, moving the push lever 121 compresses the second return spring 124, and simultaneously, the push lever 121 locks the locking lever 122. When the push rod 121 is pressed, it presses the locking rod 122 towards the first return spring 123. At this time, the protruding buckle 1211 of the push rod 121 engages with the positioning block 1111. The start button 132 is positioned opposite the switch hole 1221. Further pressing the start button 132 causes it to contact the micro switch 131, activating the hand-held stirring mechanism. Simultaneously, the start button 132 presses the push rod 121, causing the start button 132 to deform and separate from the positioning block 1111. The second return spring 124... The push rod 121 is reset according to its own elasticity. After using the hand-held stirring mechanism, the start button 132 is released. When the start button 132 and the micro switch 131 are released, the hand-held stirring mechanism stops running. The first reset spring 123 resets the locking rod 122 according to its own elasticity, thereby preventing the start button 132 from pressing down again to press the micro switch 131. Even when the power is on, children can be effectively prevented from accidentally starting the hand-held stirring mechanism when pressing the start button 132, thereby reducing potential safety hazards.

[0037] Please refer to Figure 8 , Figure 8This is a perspective view of the start button of the handheld stirring mechanism with self-locking function of the present invention. The start button 132 is provided with a first fixing block 1321 for pressing the micro switch 131 and a second fixing block 1322 located on one side of the first fixing block 1321 for pressing the push rod 121. The second fixing block 1322 is provided with a first inclined surface 1323. The first end of the push rod 121 is provided with a second inclined surface 1213 adapted to the first inclined surface 1323. The first fixing block 1321 is used to press the micro switch 131, and the second fixing block 1322 is used to press the push rod 121. The first inclined surface 1323 of the second fixing block 1322 pushes the second inclined surface 1213 on the push rod 121, thereby facilitating the deformation of the push rod 121 and enabling the push rod 121 to separate smoothly from the positioning block 1111.

[0038] A fixing plate 1212 is provided at the second end of the push rod 121. A first positioning frame 1112 is provided on the fixing frame 111 to limit the push rod 121. The push rod 121 passes through the first positioning frame 1112. The second return spring 124 is sleeved on the push rod 121 and is located between the fixing plate 1212 and the first positioning frame 1112. The first positioning frame 1112 is used to limit the movement direction of the push rod 121. At the same time, the first fixing plate 1212 and the first positioning frame 1112 are used to limit the second return spring 124 to prevent the second return spring 124 from separating from the push rod 121.

[0039] Please refer to Figure 5 , Figure 5 This is a perspective view of the fixing frame of the handheld stirring mechanism with self-locking function of the present invention. The fixing frame 111 is also provided with a second positioning frame 1113 for limiting the movement direction of the locking rod 122. The second positioning frame 1113 is used to limit the movement direction of the locking rod 122 and at the same time to limit the first return spring 123 to prevent the first return spring 123 from separating from the locking rod 122.

[0040] In this embodiment, the push rod 121 is made of an elastic material.

[0041] The locking rod 122 is also provided with a fixing hole 1222 located on one side of the switch hole 1221. A third inclined surface 1223 is provided on the side of the fixing hole 1222 near the second inclined surface 1213. The third inclined surface 1223 is inclined in the same direction as the first inclined surface 1323. The fixing hole 1222 is used to facilitate the passage of the push rod 121. At the same time, when the second inclined surface 1213 of the push rod 121 pushes the third inclined surface 1223 of the fixing hole 1222, it can limit the movement direction of the locking rod 122, so that the switch hole 1221 and the first fixing block 1321 are positioned opposite each other, so that the first fixing block 1321 can press the micro switch 131.

[0042] The starting device 13 is also provided with a fixing frame 133 for fixing the start button 132 and a third return spring located in the fixing frame 133. The third return spring is sleeved on the start button 132. The fixing frame 133 is used to fix the start button 132 and prevent the start button 132 from separating from the housing 11. At the same time, the third return spring is used to facilitate the reset of the start button 132, thereby effectively ensuring that the start button 132 is separated from the micro switch 131 when the start button 132 is not pressed.

[0043] The unlocking device 12 is also provided with an unlocking button 125 connected to the outside of the housing 11. The unlocking button 125 is connected to the push rod 121. The unlocking button 125 is used to facilitate pushing the push rod 121 and to facilitate pressing the push rod 121.

[0044] The unlocking device 12 is also provided with a fourth reset spring 126, which is located inside the unlock button 125. The fourth reset spring 126 is used to reset the unlock button 125. When the unlock button 125 is stopped being pressed, the fourth reset spring 126 resets the unlock button 125 by means of elasticity, so that the unlock button 125 can be pressed again next time.

[0045] One end of the housing 11 is also provided with a drive device 14 connected to the micro switch 131. The drive device 14 includes a bracket 141 connected inside the housing 11 and a motor 142 connected to the bracket 141. The drive device 14 is used to facilitate the processing of food by tools such as knives. The bracket 141 is used to facilitate the fixing of the motor 142 to the housing 11.

[0046] Working principle: When the handheld blender mechanism is in the self-locking state, before using the handheld blender, first press the unlock button 125. The fourth return spring 126 deforms within the unlock button 125, and simultaneously, the unlock button 125 drives the push rod 121 to move towards the locking rod 122. Furthermore, the second inclined surface 1213 of the push rod 121 presses against the third inclined surface 1223 within the fixing hole 1222 of the locking rod 122, causing the push rod 121 to move the fixing hole 1222 towards the first fixing block 1321. Due to the action of the unlock button 125... When the locking lever 122 presses the first return spring 123, and the protruding buckle 1211 of the push lever 121 engages with the positioning block 1111, the switch hole 1221 of the locking lever 122 is aligned with the first fixing block 1321 of the start button 132. The unlock button 125 is released, and the fourth return spring 126 resets the unlock button 125. Further, pressing the start button 132 causes the first fixing block 1321 of the start button 132 to extend into the switch hole 1221 and press the micro switch 131, causing the motor 142 to rotate. While the fixed block 1321 presses against the first fixed block 1321, the start button 132 presses against the third return spring. The third return spring deforms, and the first inclined surface 1323 of the second fixed block 1322 presses against the second inclined surface 1213 of the push rod 121. The push rod 121 deforms and separates from the positioning block 1111. The push rod 121 returns to its original position under the elastic force of the second return spring 124, thus facilitating the next operation. Furthermore, after using the handheld stirring mechanism, releasing the start button 132 stops the motor 142 from rotating, and the third return spring... The spring resets the start button 132 according to its elastic force. When the start button 132 moves away from the switch hole 1221, the first reset spring 123 moves the switch hole 1221 of the locking rod 122 toward the push rod 121 according to its own elastic force. At this time, the switch hole 1221 is located on one side of the first fixing block 1321, thereby preventing the start button 132 from pressing down and touching the micro switch 131. The above operation can be repeated when using it again. This can effectively prevent children from randomly pressing the start button to start the hand-held stirring mechanism, effectively reducing the existence of safety hazards and making it safer to use.

[0047] This preferred embodiment of the handheld stirring mechanism with a self-locking function works by having a push rod engage with a positioning block when unlocked. The push rod presses the switch hole toward the start button, with the start button positioned opposite the switch hole. In use, pressing the start button compresses the micro switch and simultaneously compresses the push rod, causing it to deform and separate from the positioning block. The push rod then resets according to the second return spring. When the start button is released, it moves away from the switch hole, and the first return spring resets the locking rod, preventing the start button from being pressed down. Even when powered on, this effectively prevents children from accidentally activating the handheld stirring mechanism while pressing the start button, thus reducing safety hazards.

[0048] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
