[0031] The invention provides a cake making machine with shielding.

[0032] In one embodiment of the present invention, Figures 1 to 6As shown, the pancake making machine with shielding includes: a pancake baking assembly and a limiting structure; the pancake baking assembly includes a mounting shell 10, an upper baking plate 11, a sliding sleeve 12 and a lower baking plate, the mounting shell 10 is provided with a sliding hole 101, the lower baking plate is mounted below the mounting shell 10, the upper baking plate 11 is liftably connected to the mounting shell 10, the upper baking plate 11 and the lower baking plate are arranged opposite to each other, the sliding sleeve 12 is installed above the upper baking plate 11, and the sliding sleeve 12 is slidably connected to the sliding hole 101; the limiting structure is arranged between the outer wall of the sliding sleeve 12 and the inner wall of the sliding hole 101, and when the upper baking plate 11 descends to a preset position, the limiting structure is used to limit the upper baking plate 11 from moving toward the baking plate.

[0033] The sliding sleeve 12 is arranged on the outer sleeve of the upper baking tray 11, and a limiting structure is arranged between the sliding sleeve 12 and the outer wall and the inner wall of the sliding hole 101. The upper baking tray 11 will drive the sliding sleeve 12 to move a certain distance from top to bottom. At this time, there is a certain gap between the upper baking tray 11 and the upper side of the mounting shell 10, and the sliding sleeve 12 can block the gap. The limiting structure will fix the sliding sleeve 12 and the mounting shell 10 relatively to prevent the sliding sleeve 12 from escaping from the sliding hole. This arrangement ensures that the sliding sleeve 12 can block the upper part of the upper baking tray 11, thereby preventing impurities from entering the upper part of the upper baking tray 11, thereby preventing the upper baking tray 11 from being damaged or the driving device controlling the sliding of the upper baking tray 11 from being damaged.

[0035] Specifically, the first limiting structure is arranged on the outer wall of the first sliding sleeve 121, so that the structure or circuit above the upper baking tray 11 can be prevented from interfering with the first limiting structure. The second limiting structure is arranged on the inner wall of the sliding hole 101, and no additional external structure is required. In this way, the first limiting structure and the second limiting structure are slidably connected to realize the sliding connection between the first sliding sleeve 121 and the mounting bracket. In some other embodiments, the limiting structure includes a first limiting structure arranged on the inner wall of the first sliding sleeve 121 and a second limiting structure arranged on the outer wall of the sliding hole 101.

[0036] In one embodiment, the first limiting structure is one of the limiting protrusion 122 and the limiting groove 102 , and the second limiting structure is the other one. The limiting protrusion 122 is slidably matched with the limiting groove 102 , and the groove side wall of the limiting groove 102 is used to abut the limiting protrusion 122 .

[0037] Specifically, the limiting card protrusion 122 is inserted into the limiting groove 102, and the limiting card protrusion 122 can slide in the limiting groove 102, and the groove side wall of the limiting groove 102 in the length direction is used to abut against the limiting card protrusion 122. When the limiting card protrusion 122 abuts against the limiting groove 102, the groove side wall of the limiting groove 102 can limit the movement of the limiting card protrusion 122 along the length direction. Such a structure is simple and can play a limiting role under the premise of satisfying the sliding fit.

The inner wall of the mounting shell 10 is recessed to form the limiting groove 102, and the limiting groove 102 extends along the height direction of the mounting shell 10.

[0039] Specifically, the limiting clamping protrusion 122 is convexly arranged on the outer peripheral wall of the first sliding sleeve 121, and the first sliding sleeve 121 and the sliding hole 101 are in clearance fit, but the limiting clamping protrusion 122 is always inserted in the limiting groove 102, and the limiting groove 102 extends from top to bottom. Such a setting does not affect the fit between the first sliding sleeve 121 and the sliding hole 101, and can also achieve the purpose of the limiting clamping protrusion 122 slidingly inserted in the limiting groove 102, and the limiting clamping protrusion 122 is integrally formed with the first sliding sleeve 121, and the mounting shell 10 and the limiting groove 102 are integrally formed, so that the setting is convenient for molding and saves production costs.

Such an arrangement can increase the connection stability between the first sliding sleeve 121 and the mounting shell 10, and can improve the limiting effect of the mounting shell 10 on the first sliding sleeve 121, ensuring that the upper baking tray 11 does not exceed the stroke, and can also ensure that the first sliding sleeve 121 does not deflect during the sliding process. In some other embodiments, multiple limiting protrusions 122 are arranged on the outer peripheral wall of the first sliding sleeve 121 at gradually increasing intervals, and multiple limiting grooves 102 are arranged on the inner wall of the pancake chamber, and the limiting protrusions 122 and limiting grooves 102 are arranged one by one.

[0042] In one embodiment, the sliding sleeve 12 includes a second sliding sleeve 124, the first sliding sleeve 121 is sleeved on the second sliding sleeve 124 and is slidably connected to the second sliding sleeve 124, the second sliding sleeve 124 is installed above the upper baking tray 11, and a locking structure is provided between the first sliding sleeve 121 and the second sliding sleeve 124. When the upper baking tray 11 descends to a preset position, the locking structure is used to prevent the second sliding sleeve 124 from separating from the first sliding sleeve 121.

[0043] Specifically, the second sliding sleeve 124 is directly installed above the upper baking tray 11, and the first sliding sleeve 121 is sleeved on the outside of the second sliding sleeve 124, and a locking structure is provided between the second sliding sleeve 124 and the outer wall and the inner wall of the first sliding sleeve 121.

The groove sidewalls of the sliding groove 123 in the length direction are used to abut against the sliding clamping protrusion 125. When the sliding clamping protrusion 125 abuts against the sliding groove 123, the groove sidewalls of the sliding groove 123 can limit the movement of the sliding clamping protrusion 125 along the length direction. Such a structure is simple and can play a limiting role under the premise of satisfying the sliding fit.
