Description

Technical Field

[0001] This utility model relates to the field of maternal and infant electrical appliances technology, specifically to a blower drying structure for a baby bottle cleaner and the baby bottle cleaner itself. Background Technology

[0002] With the advancement of technology, automatic bottle washer machines have become widely available in households. They can clean small baby items and other small objects, such as bottles, teething toys, nipples, and other products of various shapes, as well as tableware. During use, the items are typically rinsed with water first and then dried to ensure they remain dry after cleaning and reduce bacterial growth. However, in actual use, because bottle washer machines use water for cleaning, splashes or residual water during operation can enter the machine through the drying pipes, posing a certain safety hazard.

[0003] A search of existing technologies revealed that solutions to this problem have already been proposed in the prior art. For example, the drying system and bottle cleaner for a baby bottle cleaner (publication number CN209808278U) include a drying system that uses an air heater to heat the airflow generated by a fan. The airflow enters the corresponding pipe of the bottle cleaner through an inverted U-shaped pipe to dry the bottles. In particular, it has a check valve at the highest point of the inverted U-shaped pipe to further prevent splashed water from entering the machine body, thus achieving a backflow prevention function, solving the water ingress problem and improving the safety of use.

[0004] However, if the water vapor generated during the drying process is not discharged from the machine in time, it will flow back through the drying system pipes after the machine finishes working. Although the check valve has a certain blocking effect, it cannot prevent water vapor from passing through the tiny gaps in the check valve. When the water vapor condenses into small liquids, it will enter the machine. The existing structure cannot remove water droplets from the machine in time, which poses a certain safety risk. Utility Model Content

[0005] To reduce the risk of water entering the interior of existing baby bottle washing machines, this utility model provides a blower drying structure and a baby bottle washing machine. By setting a drain port in the pipe of the blower drying structure, condensed water can be smoothly discharged outside the machine, thereby improving the safety of product use.

[0006] The present invention adopts the following technical solution: A blowing and drying structure for a baby bottle washing machine includes an air inlet duct, an anti-backflow duct, and an air outlet duct connected in sequence. The air inlet duct is located below the anti-backflow duct. A fan and a heater are arranged in sequence along the blowing direction in the air inlet duct. A drain outlet is provided in the air inlet duct. The drain outlet is located between the heater and the outlet of the air inlet duct, and is located at the lowest point of the bottom wall of the air inlet duct.

[0007] Furthermore, the air inlet duct includes a horizontal air duct and a vertical air duct connected upwards, the fan, heater and drain outlet are located in the horizontal air duct, and the drain outlet is located below the vertical air duct.

[0008] Furthermore, the anti-backflow channel is an inverted U-shaped pipe, with an anti-backflow structure installed in the vertical pipe or vertical air duct on its air inlet side. The anti-backflow structure includes an anti-backflow valve plate, which is hinged to the corresponding pipe side wall, allowing the anti-backflow valve plate to rotate freely. An anti-backflow limiting part is provided on the lower side of the anti-backflow valve plate. When air enters the pipe, the airflow acts on the anti-backflow valve plate to open it, allowing the pipe to flow smoothly. When there is no airflow in the pipe, the anti-backflow valve plate closes on the anti-backflow limiting part under its own weight, sealing the pipe to prevent backflow.

[0009] Furthermore, one side edge of the anti-backflow valve plate is connected to a hinge shaft with two outwardly extending ends, and a hinge seat is provided for the corresponding pipe. The two ends of the hinge shaft are rotatably connected to the hinge holes of the corresponding hinge seat.

[0010] Furthermore, the anti-backflow limiting part is located at the outlet end of the vertical air duct. It includes a plate with a through hole, and an upwardly protruding annular body is provided on the plate. The upper end face of the annular body is a mating plane with the anti-backflow valve plate. The hinge seat is located on the plate. The vertical air duct is inserted into the anti-backflow duct.

[0011] Furthermore, the air outlet is located above the air inlet, and the outlet end of the air outlet is connected to the cleaning tank of the bottle washing machine, with its outlet end being higher than the highest water level in the cleaning tank.

[0012] This utility model also provides a baby bottle cleaning machine, which includes the blowing and drying structure of the baby bottle cleaning machine described above.

[0013] The advantages of this utility model compared to the prior art are as follows: This device features a drain outlet at the low end of the air inlet duct, allowing condensed water droplets to drain smoothly and promptly. Simultaneously, a backflow prevention structure is incorporated, utilizing airflow to activate the anti-backflow valve plate and its own weight to automatically open and close the valve plate. This reduces splashing water backflow and slows the inflow of obstructing liquid, facilitating smooth liquid drainage and improving product safety. Attached Figure Description

Detailed Implementation

[0016] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates the blowing and drying structure of a baby bottle washing machine and the baby bottle washing machine itself. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0017] like Figure 1 , Figure 2 As shown, a blowing and drying structure for a baby bottle washing machine includes an air inlet duct 100, an anti-backflow duct 200, and an air outlet duct 300 connected in sequence. All air ducts and flow channels are made of plastic. Considering the molding process of plastic parts, each air duct and flow channel can be assembled using methods such as snap-fitting and fastening to form its own structure. Then, corresponding interconnected pipe structures can be formed using methods such as insertion, snap-fitting, and fastener connection. For example, each air duct and flow channel can adopt a half-structure of the Haval type and be connected by snap-fit ​​assembly.

[0018] The air inlet duct 100 is located below the anti-backflow duct 200, which has an inverted U-shaped structure. The air outlet duct 300 is located above the air inlet duct 100, and its outlet end is connected to the cleaning chamber of the bottle washing machine, with its outlet end higher than the highest water level in the cleaning chamber.

[0019] In this embodiment, the air inlet duct 100 includes a horizontal air duct 110 and a vertical air duct 120 connected and arranged upwards. A fan 101, a heater 102, and a drain outlet 103 are sequentially arranged along the airflow direction in the horizontal air duct 110. In the figure, the fan 101 is located at the end of the horizontal air duct 110 and is fixedly connected inside the cleaning chamber. The heater 102 is an air heater, such as a PCT ceramic heater with heat dissipation fins. The drain outlet 103 is located on the bottom wall of the horizontal air duct 110, at the lowest point of the duct, preferably directly below or to the side of the vertical air duct 120. The drain outlet 103 is a downward-extending tubular structure, allowing condensed water droplets to smoothly enter and be discharged.

[0020] Combination Figure 3As shown, an anti-backflow structure 400 is provided in the vertical pipe on the air inlet side of the anti-backflow channel 200 or in the vertical air duct 120. The anti-backflow structure 400 includes an anti-backflow valve plate 401. The shape of the anti-backflow valve plate 401 is adapted to the cross-sectional shape of the pipe. In this embodiment, the anti-backflow valve plate 401 is a rectangular plate with rounded corners on all four sides. A hinge shaft 402 is integrally formed on one edge of the plate. Both ends of the hinge shaft extend out of the anti-backflow valve plate 401 and are coaxially arranged. A hinge seat 403 is provided in the corresponding pipe. The hinge shaft 402 is rotatably connected to the hinge hole of the corresponding hinge seat 403, allowing the anti-backflow valve plate 401 to rotate freely at the hinge point. An anti-backflow limiting part 410 is provided on the lower side of the anti-backflow valve plate 401. The anti-backflow limiting part 410 acts as a fixing member to limit the rotation limit of the anti-backflow valve plate 401, and allows the lower edge of the anti-backflow valve plate 401 to be horizontally attached to the upper surface of the anti-backflow limiting part 410. When air enters the vertical air duct 120 (as shown by the arrow in the figure), the airflow acts on the anti-backflow valve plate 401 to open it, allowing the duct to flow smoothly. When there is no airflow in the vertical air duct 120, the anti-backflow valve plate 401 closes onto the anti-backflow limiting part 410 under its own weight, sealing the duct to prevent backflow and reduce water vapor entering the machine body. Of course, in order for the anti-backflow valve plate 401 to close by its own weight, the center of gravity of the corresponding anti-backflow valve plate 401 in the open and closed state should not be in the same vertical plane as the center of the hinge axis, and the center of gravity should be biased towards the closed side. For example, by setting the anti-backflow valve plate 401 as an upwardly convex plate, the convex part can be used to press against the side wall of the pipe body. Figure 3 As shown), this prevents the anti-backflow valve plate 401 from opening to 90°, thereby achieving a shift in the center of gravity position.

[0021] To facilitate the installation of the anti-backflow structure, it is preferable to position the anti-backflow limiting part 410 at the outlet end of the vertical air duct 120, specifically in conjunction with... Figure 4 As shown, the anti-backflow limiting part 410 includes a plate 411 with a through hole. The plate 411 is located at the outlet end of the vertical air duct 120. The plate 411 has an upwardly protruding, roughly rectangular annular body 412. The upper end surface of the annular body 412 is a mating plane with the anti-backflow valve plate 401, and the annular body 412 can be inserted entirely into the anti-backflow channel 200. The hinge seat 403 is located on the plate 411 and is located on one side. This structural design reduces the manufacturing difficulty of the anti-backflow structure 400 and also facilitates assembly.

[0022] The air outlet duct 300 is located above the air inlet duct 100. It has a vertical section 301 connected to the anti-backflow duct 200 and a horizontal section 302 connected to the cleaning box of the bottle washing machine. The outlet end of the air outlet duct 300 is sealed and connected to the inside of the cleaning box through a sleeved seal 303. The outlet end is higher than the highest water level in the cleaning box to reduce the backflow of splashed water stains.

[0023] In addition, this utility model also provides a baby bottle cleaning machine that adopts the above-mentioned blowing and drying structure.

[0024] This device features a drain outlet at the bottom of the air inlet duct, allowing condensed water droplets to drain smoothly and promptly. Simultaneously, a backflow structure reduces the backflow of splashed water and slows the inflow of backflowing liquid, facilitating smooth drainage and thus improving product safety.

[0025] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
