Description

Technical Field

[0001] The embodiments of the present application relate to the field of stirrers, and in particular to a waterproof electric stirrer. Background Art

[0002] In the current market, the designs of many electric stirrers have not yet completely solved the waterproof problem, which is reflected in the following aspects:

[0003] 1. Insufficient protection of the motor and circuit: Although some electric blenders claim to have a certain degree of waterproof ability, in fact, the motor part and internal circuit are easily damaged under long-term immersion or direct impact of water flow, affecting the service life and safety.

[0004] 2. Design defects of seams and buttons: The shell seams of many products are not tight enough, and the areas around buttons and knobs often become weak links for moisture intrusion, which may cause rust or short circuit problems after long-term use.

[0005] 3. Lack of waterproof treatment on the handheld part: During frequent contact with food and cleaning, although the handheld part directly interacts with the user, it often lacks effective waterproof sealing measures, causing the internal electronic components to be at risk of moisture.

[0006] 4. Cleaning and maintenance challenges: Due to the limitation of waterproof performance, users need to be extra careful when cleaning the electric blender to avoid the motor part coming into contact with water. This not only increases the difficulty of cleaning, but may also lead to safety accidents due to improper operation.

[0007] 5. Different waterproof levels of accessories: Even if the main part has a certain waterproof design, the accessories of the electric stirrer, such as between the shells, often have structural gaps and are difficult to meet the same waterproof standards as the main unit, limiting the overall waterproof performance.

[0008] In summary, the electric stirrer in the prior art still has a lot of room for improvement in terms of waterproof performance. Users need to pay attention to waterproof measures during use and maintenance. Utility Model Content

[0009] The embodiment of the present application provides a waterproof electric blender, which at least solves one problem of the above-mentioned prior art. The product integrates sophisticated waterproof technology in multiple key parts to ensure safety and durability in kitchen operations, and can easily cope with direct water washing.

[0011] In some embodiments, a power supply unit, a circuit board electrically connected to the power supply unit, and a motor are disposed inside the shell, and a motor output end of the motor is transmission-connected to the stirring member.

[0012] In some embodiments, a waterproof boss with a reserved perforation that can pass through the motor output end is provided at the front of the inner shell, and a sealing shaft is provided inside the waterproof boss, which can prevent water vapor or water droplets from entering the interior of the inner shell through the perforation.

[0013] In some embodiments, a silicone base is also installed at the bottom of the bottom shell, and the silicone base can prevent moisture or water droplets from entering the interior of the inner shell through the power interface at the bottom of the bottom shell.

[0014] In some embodiments, a key switch is also installed on the silicone base, and the key switch is in contact with a push button on the circuit board.

[0015] In some embodiments, the front end of the outer shell is also connected to a front shell, and the front end of the front shell has a hole, and the output end of the motor can pass through the hole of the front shell to be transmission-connected to the stirring member.

[0016] In some embodiments, the outer shell has an outer shape of a cylindrical sleeve, and the outer volume of the inner shell is smaller than the outer volume of the outer shell.

[0017] The utility model discloses a waterproof electric stirrer, which has the following technical effects:

[0018] First, the electric blender cup adopts a double-layer shell structure, and the joint between the inner shell and the outer shell uses a food-grade silicone sealing ring to form a tight waterproof barrier, which effectively prevents moisture and food residues from penetrating into the body and extends the service life.

[0019] Second, for button design, we use waterproof silicone button technology to cover the surface of all operation buttons to ensure that when operating or cleaning with wet hands, water droplets cannot penetrate into the circuit board under the button, ensuring the dryness and safety of the circuit system.

[0020] Third, at the output end of the driving motor, especially at the position of the perforated connection to the stirring element, a waterproof boss sleeve and a sealing shaft are added to ensure efficient power transmission and prevent moisture from entering the interior through the motor shaft hole, greatly improving the waterproof performance of the motor.

[0021] Fourth, the joints between the bottom shell and the outer shell are fixed with reinforced sealing rings and screws to ensure that the bottom is completely closed, without fear of water splashing on the desktop or water stains during cleaning, protecting the electronic components at the bottom from moisture.
