In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

Referring to fig. 1, in some embodiments, the foam device 100 includes a foam box 101, a drainage mechanism 102, and a vibration mechanism 103, the drainage mechanism 102 and the vibration mechanism 103 being disposed at the bottom of the foam box 101, and the bottom of the foam box 101 being provided with an installation space 104 accommodating the drainage mechanism 102 and the vibration mechanism 103. It will be appreciated that the frothing box 101 also has a third chamber 405, and liquid such as food material and water is placed in the third chamber 405 for frothing. The third receiving chamber 405 is located above the installation space 104 and separated by a partition 105. That is, the partition 105 divides the foaming box 101 into two parts, the third cavity 405 on the upper layer is used for containing liquid and food materials for foaming, and the installation space 104 on the lower layer is used for accommodating the drainage mechanism 102 and the vibration mechanism 103 and is used for balanced and fixed placement, so that the drainage mechanism 102 and the vibration mechanism 103 are prevented from interfering with other devices. Under the condition that the overall height of the foam box 101 is fixed, if the installation space 104 occupies a relatively large space, the effective space of the third cavity 405 is reduced, and the overall gravity center is relatively high, so that under the action of the vibration mechanism 103, relatively large noise is possibly generated, and even the foam box is overturned; however, if the installation space 104 is relatively small, the requirements of the installation space 104 for the drainage mechanism 102 and the vibration mechanism 103 cannot be satisfied, and therefore, in some embodiments, the height D1 in the installation space 104 and the height D2 of the foam box 101 satisfy the following relationship: D1/D2 is more than or equal to 0.15 and less than or equal to 0.4.

It should be noted that drainage is intended to broadly refer to drainage of water and any other liquid that may be used for foaming, and similarly, drainage mechanism 102 is intended to broadly refer to drainage of water and any other liquid that may be used for foaming.

In some embodiments, the vibration mechanism 103 includes a vibration motor 106 and a mounting bracket 107, and the vibration motor 106 is mounted to the bottom of the foam box 101 by the mounting bracket 107. Since the contact area between the bottom of the frothing box 101 and the food material is the largest, the vibration motor 106 is installed at the bottom of the frothing box 101, and compared with the installation at the side of the frothing box 101 or the like, the vibration effect can be improved, so that more food materials can be further drained of the liquid under the effect of the vibration wave provided by the vibration mechanism 103. The vibration mechanism 103 may be a device capable of generating vibration waves in the foam box 101, such as a striking mechanism, in addition to the vibration motor 106.

The cavity is capable of accommodating at least part of the vibration motor 106, reducing the volume required for the mounting space 104. Meanwhile, as the third cavity 405 is provided with the protrusion, the contact area between the food material and the vibration source is increased, the transmission of vibration waves is facilitated, and the draining effect is improved. If the cavity depth is too small, on one hand, the contact area of the protrusion is limited, and the draining improvement effect is limited, on the other hand, the cavity depth is small, the size for accommodating the vibration motor 106 is small, more space needs to be reserved in the installation space 104, and the utilization of the effective space of the foam box 101 is not facilitated. And if the cavity depth is too big, cause protruding too big, reduced the volume that third holds the chamber 405, the edible material that can place diminishes, influences the use, also influences wholly pleasing to the eye, also is not favorable to the cleanness. Thus, in some embodiments, the diameter E1 of the vibration motor 106 and the diameter E2 of the cavity satisfy the following relationship: E1/E2 is more than or equal to 0.1 and less than or equal to 0.5.

The drainage mechanism 102 is arranged in the foaming box 101, so that quick and convenient drainage can be realized, then vibration waves are provided through the vibration action of the vibration mechanism 103, the tension action between liquid and food materials is overcome, residual liquid is released from the surface gaps of the food materials, the food materials and the vessels, and the food materials after foaming are drained to the maximum extent; the storage effect of the soaked food materials is better. Meanwhile, the refrigeration equipment 1001 foams the food materials at a low temperature, so that the problems of nutrition loss, too fast bacterial growth and the like caused by normal-temperature or high-temperature foaming can be avoided, and the food materials can be provided with better taste and flavor by foaming at a low temperature. The refrigeration device 1001 may be a common cryogenic storage device such as a refrigerator or freezer.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
