And, on the lateral wall of defoaming piece 43 was located to bleeder vent 431, and the both sides wall of defoaming piece 43 all was equipped with bleeder vent 431 for the noise is in the more tortuous extension of the route of spreading away by the bleeder vent, can carry out better buffering that blocks to acoustic energy, with the noise that further reduction spread away, the noise of greatly reduced food preparation machine during operation, better promotion user experience and satisfaction.

It can be understood that, also be equipped with defoaming block 43 on the material lid 32 of throwing in, be equipped with the bleeder vent 431 with the inlet port intercommunication on the defoaming block 43, and defoaming block 43 is located through-hole department to promote the defoaming effect.

Example seven:

as shown in fig. 15, the sidewall of the upper end of the upper inner cavity 321 is provided with an air outlet 3211 communicated with the second silencing cavity 35, the exhaust structure is an exhaust groove 326 arranged on the upper annular retainer ring 325, the exhaust groove 326 is communicated with the air outlet 3211 and the air outlet channel 38, the exhaust structure can exhaust air entering the second silencing cavity well, so as to ensure the exhaust effect, and further block and attenuate noise through the second silencing cavity, so as to further improve the blocking and attenuating effect of the feeding cover on noise, and further improve the noise reduction effect of the food processor.

Example eight:

as shown in fig. 16, the side wall of the annular surrounding edge 332 is provided with a plurality of sealing ribs 3321, the sealing ribs 3321 are longitudinally arranged and the sealing ribs 3321 are uniformly arranged at intervals along the circumferential direction of the annular surrounding edge 332, so that after the air-permeable sealing plug is installed in place, the sealing ribs 3321 and the inner side wall of the upper inner cavity of the inner charging cover form an interference fit, so as to fix the air-permeable sealing plug in the upper end of the inner charging cover.

Example nine

As shown in fig. 17, the bottom of the exhaust channel 221 is provided with a partition 44 forming the lower end of the exhaust channel, and the partition 44 is also provided with a defoaming structure 4. The defoaming structure includes defoaming post 41, and defoaming post 41 is equipped with a plurality ofly and the interval sets up. The defoaming column 41 is provided with a ventilation passage 411. The partition 44 is below the dosing cap 3 and thus contacts the foam earlier than the dosing cap 3. Utilize baffle 44 to carry out first defoaming to the foam, the rethread is thrown material lid 3 and is carried out the defoaming, promotes defoaming performance greatly to better assurance exhaust effect can further block acoustic energy simultaneously, with the realization further noise attenuation, thereby further promotion noise reduction.

In addition to the above preferred embodiments, the technical solutions protected by the present invention are not limited to the above embodiments, and it should be noted that the combination of the technical solution of any one embodiment and the technical solution of one or more other embodiments is within the scope of the present invention. Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
