Description

Technical Field

[0001] The invention relates to the field of milk mixers, and in particular to a milk mixer capable of rapidly cooling down. Background Art

[0002] A milk mixer is an instrument used to adjust the temperature of water for making milk or drinking directly. Its main function is to maintain a constant water temperature, so that parents can quickly and accurately mix milk at a temperature suitable for the baby to drink. Some milk mixers are equipped with a fan device. When the temperature of the container needs to be lowered, the fan starts to accelerate the air flow on the surface of the container. According to the principle of heat exchange, the flowing air can take away the heat of the container more quickly, thereby achieving rapid cooling. When the fan is in operation, the blades and the air produce friction. This friction will cause static electricity on the surface of the fan blades. According to the principle of electrostatics, charged objects can attract light and small objects. Dust particles usually have a weak charge or are electrically neutral, but under the action of the electrostatic field, they will be adsorbed to the surface of the fan blades, which will cause the following problems:

[0003] 1. Dust adheres to the fan blades and motor shaft, which will affect the balance of the fan when it rotates. When the fan rotates, vibration is generated due to imbalance, which in turn causes increased noise;

[0004] 2. Dust contains various impurities, including microorganisms. In a humid environment, the dust attached to the surface of the fan blades provides a good place for the growth of bacteria and microorganisms, and the milk mixer is used to prepare baby food, and these bacteria and microorganisms may pose a threat to the health of the baby.

[0064] The following is a detailed description of the milk mixer capable of rapid cooling provided by the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0065] Embodiment 1:

[0066] like Figures 1 to 6 As shown, the embodiment of the present application provides a milk mixer that can quickly cool down, including an outer shell 1 and a placing bin 2, and also includes an annular shell 3, which is mounted outside the placing bin 2 and is connected to the placing bin 2 through a plurality of exhaust ports 4; a fan 5, which is installed in the outer shell 1, and the air outlet is connected to the annular shell 3 through an air duct 6; a dust filter unit 7, which is detachably installed at the bottom of the outer shell 1, connected to the air inlet of the fan 5, and filters dust in the air flow through a cylindrical filter element 71.

[0067] Furthermore, the dust filter unit 7 includes a shell cover 72, which is inserted into the bottom of the outer shell 1 through a mounting hole, the top end is sealed with the air inlet of the fan 5 by a sealing ring 73, and the bottom is hollow; an inner ring shell 74, which is fixed to the bottom of the shell cover 72 and is connected to the cylindrical filter element 71 by threads; an outer ring shell 75, which is fixed to the bottom of the outer shell 1, and the inner circumferential wall abuts against the outer circumferential wall of the shell cover 72; a pair of quick-release devices 8, used to make the outer ring shell 75 detachably connected to the shell cover 72.

[0068] Furthermore, the quick-release device 8 includes a bayonet 81, which is arranged on the inner wall of the outer ring shell 75; a through groove 82, which is arranged on the peripheral wall of the shell cover 72; a floating connector 83, which is slidably installed in the through groove 82; and a reset member 84, which is used to control the floating connector 83 to disengage from the slot.

In this process, the inclined outer end surface of each telescopic sleeve 832 first contacts the bottom surface of the outer shell 1, and then each telescopic sleeve 832 is pushed into the corresponding through groove 82, until each telescopic sleeve 832 moves to a position corresponding to the corresponding bayonet 81, and the corresponding locking spring 833 releases its elastic potential energy, pushing the outer end of each telescopic sleeve 832 into the corresponding bayonet 81, thereby completing the replacement of the cylindrical filter element 71.

[0073] Embodiment 2:

[0074] like Figures 3 to 5As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the dust filter unit 7 also includes a plurality of ash discharge holes 76, which are circumferentially spaced apart at the bottom of the shell cover 72 and the inner side of the inner ring shell 74; a lifting frame 77, which is passed through the shell cover 72 and has a disc 78 fixed at the top; a plurality of cleaning rods 79, which are circumferentially spaced apart and fixed on the peripheral wall of the disc 78; and a plurality of ash retaining grooves 710, which are circumferentially spaced apart and fixed on the inner peripheral wall of the cylindrical filter element 71, and the bottom of the inner cavity is connected to the corresponding ash discharge holes 76.

[0076] Furthermore, the lifting frame 77 includes a sleeve rod 771, which is fixed on the bottom surface of the disc 78, with the upper end of the inner cavity passing through the center of the disc 78 and the lower end closed; a pair of slots 772 are symmetrically arranged at the bottom of the shell cover 72, respectively located on both sides of the sleeve rod 771; a clamping member 9 is horizontally telescopically slidably installed at the bottom of the sleeve rod 771, used to engage with the slot 772; a telescopic member 10 is horizontally telescopically slidably installed at the bottom of the sleeve rod 771, and cooperates with the clamping member 9 in transmission. When the clamping member 9 is disengaged from the slot 772, the telescopic member 10 extends out of the sleeve rod 771.

[0077] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to clean the cylindrical filter element 71, a pair of engaging members 9 are pressed to disengage them from the engaging with the corresponding engaging grooves 772, and at the same time, each telescopic member 10 is extended, and the user's fingers can come into contact with the telescopic members 10 on both sides, and then the sleeve rod 771 is rotated to rotate the turntable and each rod body 791, and the dust accumulation groove 792 of each rod body 791 moves toward the corresponding dust blocking groove 710, and the dust on the inner surface of the cylindrical filter element 71 is swept off by the brush and accumulated in the dust accumulation groove 792 until each rod body 791 enters the corresponding dust blocking groove 710 and the lower end Aim at the corresponding ash discharge hole 76, and then pull the sleeve rod 771 outward to make each rod body 791 extend out of the corresponding ash discharge hole 76. Then people can use paper towel wiping, vacuum cleaner cleaning or other cleaning methods to clean the dust in the dust accumulation groove 792. After that, press the sleeve rod 771 into the shell cover 72 until each rod body 791 completely enters the inner cavity of the cylindrical filter element 71, and then rotate the sleeve rod 771 to make each engaging member 9 move to correspond to the corresponding slot 772 and engage with the corresponding slot 772. Correspondingly, each telescopic member 10 also retracts into the sleeve to complete the cleaning operation of the cylindrical filter element 71.

[0078] Embodiment 3:

[0079] like Figures 4 to 6As shown in the figure, in this embodiment, in addition to including the structural features of the foregoing embodiment, the engaging member 9 includes a pair of engaging frames 91, which are longitudinally cut into a U-shape, and both the upper and lower ends extend out of the sleeve rod 771. The upper end thereof can be engaged with the corresponding card slot 772, and the transverse cross-section is fan-shaped; a pair of return springs 92 are respectively arranged at the bottom of each engaging frame 91 through the corresponding return cavity 93; the return push rod 94 passes through each return cavity 93 at both ends and abuts against the end portions of each return spring 92.

[0080] Further, the telescopic member 10 includes a pair of telescopic rods 101, which are symmetrically arranged through the bottom of the sleeve rod 771 and are perpendicular to the return push rod 94; a pair of arc-shaped plates 102 are respectively fixed to the outer ends of each telescopic rod 101; a plurality of dovetail chutes are respectively arranged on the side walls of each engaging frame 91; a plurality of dovetail sliders 103 are respectively arranged on the side walls of each telescopic rod 101 and are slidably matched with the adjacent dovetail chutes.

The pair of engaging frames 91 approach each other. Since the side walls of each engaging frame 91 are inclined, at the same time, each telescopic rod 101 is pushed to extend out of the sleeve, and each dovetail slider 103 slides in the corresponding dovetail chute until the upper ends of the pair of engaging frames 91 are disengaged from the corresponding card slots 772, and the adjacent inner ends are abutted tightly. The arc-shaped plates 102 at the outer ends of each telescopic rod 101 are higher than the outer ends of the adjacent engaging frames 91, forming two recessed portions on both sides of the bottom of the sleeve, which is convenient for the operator to hold. When it is necessary to insert the upper ends of the pair of engaging frames 91 into the corresponding card slots 772, release the pressing on the pair of engaging frames 91, and each return spring 92 releases elastic potential energy, pushing the pair of engaging frames 91 to separate from each other. At the same time, each dovetail slider 103 is slidably matched with the dovetail chute, pulling the pair of telescopic rods 101 to retract into the sleeve until the inner ends of each telescopic rod 101 contact the outer wall of the return push rod 94, and the upper ends of each engaging family are engaged with the corresponding card slots 772.
