Description

Technical Field

[0001] This utility model relates to the field of blender technology, specifically a vacuum blender. Background Technology

[0002] Existing vacuum blenders (such as patent number ZL202322335485.7) include a base, a cup body, a lid, a vacuum tube holder, a first housing, and a second housing. The base houses a controller, a vacuum pump, a drive motor, and an electromagnetic control valve. The controller is electrically connected to the vacuum pump, drive motor, and electromagnetic control valve. The cup body and vacuum tube holder are both mounted on the base, with the vacuum tube holder located on one side of the cup body. The vacuum tube holder includes a vacuum tube holder body and an upper connecting rod, which are movably connected. One end of the upper connecting rod is embedded in the top of the vacuum tube holder body, and the end of the upper connecting rod away from the vacuum tube holder body is provided with silicone. The nozzle, a silicone nozzle, is connected to the vacuum pump's air circuit at one end via a vacuum tube. The vacuum tube is located inside the vacuum tube holder and communicates with the electromagnetic control valve. The lid is attached to the cup body and has a first air hole and an inner cover. The inner cover is detachably connected to the lid body, and the center of the inner cover has a vacuum exhaust column. A one-way valve is embedded in the exhaust column and communicates with the first air hole. A silicone inner sleeve is fixedly connected between the exhaust column and the one-way valve. The silicone nozzle covers and fits snugly against the upper surface of the lid body. The second shell is fixedly connected to the vacuum tube holder, and the first shell is fitted over the second shell and movably connected to it. In this design, after placing fruits and vegetables into the cup body and closing the lid, the upper connecting rod must be lowered first to allow the silicone nozzle to cover the one-way valve and fit snugly against the lid body. Then, the soundproof cover must be closed before vacuuming can begin. After blending, when removing the cup body, the soundproof cover must be removed first, and then the upper connecting rod raised to remove the cup body. This requires repeated installation / removal of the soundproof cover and adjustment of the upper connecting rod position, which is cumbersome and can easily lead to a poor user experience. Moreover, the upper connecting rod is only supported by the movable hinged cantilever, which may sag, have insufficient rebound, or wobble after long-term use. This can cause the silicone nozzle and the one-way valve to become misaligned, resulting in sealing failure and reduced vacuuming efficiency. Utility Model Content

Figure 2 This is a cross-sectional structural diagram of this application. This embodiment provides a vacuum blender, including a base 1, a cup body 2, a cover 3, a soundproof seat 4, a soundproof cover 5, and a vacuum tube rack 6.

[0021] See also Figure 1The soundproof base 4 is located on the outside of the cup body 2 and is detachably connected to the base 1. Specifically, the soundproof base 4 can be snapped to the base 1 via a second positioning stop, or it can be detachably fixed to the base 1 via bolts or other fasteners. The soundproof cover 5 is fitted onto the soundproof base 4 and rotatably connected to the soundproof base 4. Specifically, the soundproof base 4 is provided with a hinge support 41, and the hinge support 41 is provided with a horizontal damping hinge. The soundproof cover 5 is rotatably connected to the soundproof base 4 via the horizontal damping hinge. The soundproof cover 5 integrates an upper connecting rod 51. Specifically, the upper connecting rod 51 of the soundproof cover 5 is detachably fixed to the soundproof cover 5 via bolts or other fasteners, or it can be fixed to the soundproof cover 5 by snap-fitting or other methods. (See also...) Figure 2 , Figure 3 and Figure 4 The upper connecting rod 51 is hollow inside, and its two ends are respectively provided with a first silicone air nozzle 511 and a second silicone air nozzle 512. The first silicone air nozzle 511 and the second silicone air nozzle 512 are connected by an air passage. The first silicone air nozzle 511 covers the first annular sealing surface 32 and is sealed and fitted to the first annular sealing surface 32. The sound insulation seat 4 and the sound insulation cover 5 are both three-layer composite structures. The inner layer is a 3-5mm thick high-density rubber and plastic closed-cell foam layer, the middle layer is an 8-10mm corrugated polyurethane sound-absorbing cotton, and the outer layer is an ABS plastic shell with sound insulation particles sprayed on the surface, so as to effectively absorb and isolate the high-frequency noise generated during the wall breaking, and reduce the noise to below 30 decibels. See also Figure 2 The vacuum tube frame 6 is located between the sound insulation base 4 and the cup body 2, and is detachably connected to the base 1. The vacuum tube frame 6 can be snapped to the base 1 through the third positioning stop, or it can be detachably fixed to the base 1 through bolts or other fasteners. The vacuum tube frame 6 is hollow inside, and its top is provided with a suction nozzle 61. The vacuum tube frame 6 is provided with a second annular sealing surface 62 on the outside of the suction nozzle 61. The suction nozzle 61 is connected to the vacuum pump 12 through a vacuum tube. An electromagnetic control valve 14 is connected in series on the vacuum tube. The second silicone nozzle 512 covers the second annular sealing surface 62 and is sealed and fitted to the second annular sealing surface 62. As the soundproof cover 5 is closed, a physically sealed air passage connection is established between the soundproof cover 5, the cover 3, and the vacuum tube frame 6. Compared with the traditional direct insertion and removal of hoses, this method of connection is more stable, the airtightness is better guaranteed, and the long-term durability is good. It can avoid the risk of air leakage caused by hose aging, bending, insertion and removal wear.

[0022] When in use, the lid 3 is sealed onto the cup body 2. The soundproof cover 5 is rotated to close, so that the first silicone nozzle 511 of the upper connecting rod 51 is sealed to the first annular sealing surface 32 of the lid 3, and the second silicone nozzle 512 is sealed to the second annular sealing surface 62 of the vacuum tube frame 6. There is no need to readjust the position of the upper connecting rod 51. The controller 11 starts the vacuum pump 12 and controls the air extraction passage through the electromagnetic control valve 14. The air in the cup is discharged sequentially through the one-way valve 35, the first air extraction hole 31, the first silicone nozzle 511, the second silicone nozzle 512, the air extraction nozzle 61, and the vacuum tube. When the vacuum degree reaches the set value, the controller 11 closes the electromagnetic control valve 14 and stops the vacuum pump 12. The drive motor 13 then drives the rotating blade assembly 21 to rotate at high speed to break the wall. After the wall breaking is completed, the cup body 2 needs to be removed. The controller 11 closes the vacuum pump 12 and opens the vent valve 38, so the soundproof cover 5 can be opened and the cup body 2 can be removed to pour out the food. The controller 11 controls the solenoid valve to release the air pressure in the vacuum tube. The first silicone nozzle 511 and the first annular sealing surface 32, and the second silicone nozzle 512 and the second annular sealing surface 62 are no longer tightly fitted. The cup body 2 can be removed without raising the upper connecting rod 51 in the vacuum tube frame 6. The operation is simpler and the sound insulation effect is better.

[0023] In summary, this application integrates the upper connecting rod 51 device onto the soundproof cover 5, completely avoiding the problems of sagging, insufficient rebound, or lateral wobbling of the upper connecting rod 51 causing misalignment between the silicone nozzle and the one-way valve 35, resulting in sealing failure. Secondly, the vacuum passage of this application is completely hidden inside the soundproof cover 5, the vacuum tube frame 6, and the upper connecting rod 51, with no exposed pipes. The first silicone nozzle 511 is attached to the first annular sealing surface 32 of the cover 3, and the second silicone nozzle 512 is attached to the second annular sealing surface 62 of the vacuum tube frame 6, forming a fully concealed vacuum passage. The vacuuming function can be used by closing the soundproof cover 5, and the large cup can be taken out by opening the soundproof cover 5 after vacuuming, making the operation simpler.

[0024] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
