Technical Field

[0001] This utility model relates to the field of bottle warmer technology, and in particular to a bottle warmer. Background Technology

[0002] Chinese patent document CN220898493U, published on May 7, 2024, discloses a shakeable bottle warmer. The shakeable bottle warmer includes a heating element, a rotating shaft, a connecting member, a cradle, and a water tank. The heating element is heat-transferringly connected to the outer wall of the water tank. The rotating shaft rotatably passes through the bottom of the connecting member, which includes a groove. The cradle is detachably positioned and fixed via the groove on the connecting member. The cradle is used to hold a bottle and includes a clamping part for securing the bottle. The motor shaft of this bottle warmer is connected to the cradle via the connecting member, resulting in a complex assembly structure with many parts, thus increasing manufacturing costs. Furthermore, the bottle warmer uses a plastic bracket to fix the motor. This plastic bracket is positioned close to the heating element, allowing heat to be transferred to it. The plastic bracket is prone to deformation due to high temperatures, affecting product stability and potentially causing oil seal failure, leading to water and electrical leaks and posing a high safety hazard.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a bottle warmer that is simple in structure, low in cost, highly stable, safe and reliable, and highly practical, so as to overcome the shortcomings of the prior art.

The cradle is disposed inside the inner liner, and the heating element is disposed at the bottom of the inner liner. The cradle is detachably connected to the output shaft of the motor, and a high-temperature resistant bracket is provided at the bottom of the heating element. The motor is fixed on the high-temperature resistant bracket.

[0006] The bottom of the cradle is equipped with a first buckle, and the bottom of the inner liner is equipped with a second buckle. A bearing is provided between the first buckle and the second buckle. The upper and lower sides of the bearing are respectively equipped with a first fastening part and a second fastening part. The first buckle and the second fastening part are fastened to each other, and the second buckle and the first fastening part are fastened to each other, so that the bottom of the cradle can be detachably and rotatably connected to the inner liner.

[0007] The first and second buckles are elastic, and a support block is provided at the bottom of the inner liner; When the cradle moves upward under the action of external force, the second buckle deforms elastically, so that the first fastening part disengages from the second buckle, thereby realizing the disassembly of the cradle from the inner liner. The bottom of the bearing is supported on the first buckle. Alternatively, when the cradle moves upward under the action of external force, the first buckle deforms elastically, so that the second fastening part disengages from the first buckle, thereby realizing the disassembly of the cradle from the inner liner, and the bottom of the bearing is supported on the support block.

[0008] The high-temperature resistant bracket has several positioning blocks extending downwards along its periphery, forming positioning grooves between the positioning blocks, and the upper end of the motor is inserted into the positioning grooves.

[0009] The high-temperature resistant bracket has several lugs extending outward from its periphery. Each lug has a first fixing hole. The bottom of the heating element has several fixing post holes. Fasteners pass through the first fixing holes and are then fastened to the fixing post holes to fix the high-temperature resistant bracket to the bottom of the heating element.

[0010] The bottom of the cradle has a non-circular insertion hole, the output shaft of the motor is non-circular, the heating element has a first through hole, and the bottom of the inner liner has a second through hole. The output shaft of the motor passes through the first through hole and the second through hole in sequence and is then inserted into the insertion hole.

[0011] Several protrusions extend upward from the upper side of the high-temperature resistant bracket, forming an installation groove between the protrusions. An oil seal is installed on the installation groove, and the oil seal is positioned between the heating element and the high-temperature resistant bracket, covering the first through hole.

[0012] A sealing sleeve is provided between the upper end of the motor and the high-temperature resistant bracket. The outer side of the sealing sleeve abuts against the positioning block. The high-temperature resistant bracket is provided with a third fixing hole, the sealing sleeve is provided with a fourth fixing hole, and the upper end of the motor is provided with a fifth fixing hole. Fasteners pass through the third fixing hole and the fourth fixing hole in sequence and are then fastened to the fifth fixing hole to fix the motor on the high-temperature resistant bracket.

[0013] It also includes an outer shell, with an inner liner inside the outer shell. An electrical chamber is formed between the outer shell and the inner liner. The electrical chamber is located below the inner liner. An electrical control board is installed at the bottom of the electrical chamber. The electrical control board is electrically connected to the heating element and the motor. The heating element is located at the top of the electrical chamber so that the electrical control board is positioned away from the heating element.

[0014] The high-temperature resistant bracket is a hardware component.

[0015] This invention relates to a bottle warmer that uses a detachable cradle connected to the motor's output shaft and employs clips and bearings to position the cradle. Compared to traditional cradle fixing structures, this eliminates the need for connecting parts, simplifies the cradle's assembly structure, and reduces the number of assembly parts, thereby lowering manufacturing costs. Furthermore, by installing a high-temperature resistant bracket at the bottom of the heating element, the motor is fixed to the high-temperature resistant bracket, which can withstand high temperatures and will not deform due to high temperatures. This prevents the oil seal from failing and causing water or electrical leakage, greatly improving the product's stability and safety. Attached Figure Description
