上述的保鲜盒通过抽真空的方式以达到食物与空气隔离的目的， 从而保持食物的新鲜，其通过安装在盖子上的一个抽真空装置实现这 一目的； 该抽真空装置结构如图 3、 4、 5所示， 在盖子安装有伸入保 鲜盒空腔内的空筒 31 , 其截面为圆环面， 伸入保鲜盒内部的一端包 括端壁将该空筒 31内腔与保鲜盒空腔隔开，在空筒 31内安装有可在 空筒 31内腔做往复运动的活塞杆 32 , 活塞杆 32的内侧端固定安装 有栓塞 33 , 栓塞 33为橡胶制作而成， 其与空筒 31的内壁紧密配合， 同时，在空筒 31的内端壁上设置有单向出气装置将空筒 31的内腔与 保鲜盒的空腔连通。  The above-mentioned crisper is vacuumed to achieve food and air isolation, thereby keeping the food fresh, and the object is achieved by a vacuuming device mounted on the cover; the vacuuming device structure is shown in Figures 3 and 4. 5, the cover is mounted with an empty cylinder 31 extending into the cavity of the crisper, the cross section of which is a torus, and one end extending into the interior of the crisper includes an end wall, the inner cavity of the empty cylinder 31 and the cavity of the crisper Separated, a piston rod 32 that can reciprocate in the inner cavity of the empty cylinder 31 is installed in the empty cylinder 31. The inner end of the piston rod 32 is fixedly mounted with a plug 33, which is made of rubber, and the empty cylinder 31 The inner wall is closely fitted, and at the same time, a one-way air outlet means is provided on the inner end wall of the empty cylinder 31 to communicate the inner cavity of the empty cylinder 31 with the cavity of the crisper.
上述单向出气结构如图 5所示， 在空筒 31内端壁上开设有圆通 孔 311 , 橡胶塞 34通过圆通孔 311固定在空筒 31内端壁上， 并将圆 通孔 311封闭，橡胶塞 34包括位于空筒 31内端壁外侧的圆锥台型的 凸台 341 , 位于空筒 31内端壁内侧的圆柱形凸缘 342 , 凸缘 342的横 截面的直径大于凸台 341最大横截面的直径， 并且在空筒 31内端壁 上设置有两个出气孔 312 , 出气孔 312位于空筒 31内端壁内侧面被 凸缘 342封闭， 其位于空筒 31内端壁内侧面与保鲜盒空腔连通。 As shown in FIG. 5, the one-way air outlet structure is provided with a circular through hole 311 in the inner wall of the hollow cylinder 31. The rubber plug 34 is fixed on the inner end wall of the hollow cylinder 31 through the circular through hole 311, and the circular through hole 311 is closed. The plug 34 includes a truncated cone-shaped boss 341 located outside the inner end wall of the empty cylinder 31, a cylindrical flange 342 located inside the inner end wall of the empty cylinder 31, and a transverse direction of the flange 342 The diameter of the cross section is larger than the diameter of the largest cross section of the boss 341, and two air outlet holes 312 are provided on the inner end wall of the empty cylinder 31. The air outlet hole 312 is located at the inner side surface of the inner wall of the empty cylinder 31 and is closed by the flange 342.

使用时， 向外拉动活塞杆， 空筒被栓塞隔离开的封闭腔体的体积 增大， 根据物理常识， 其封闭空腔的体积增大， 使得其内部气体压强 降低，从而造成该封闭腔体的气压与保鲜盒空腔气压的差值， 并且两 个腔体的连接处设置有出气孔，通过该气压差值构成对凸缘的一个向 上的推力， 由于凸缘为软性材料的橡胶， 其被向上推起， 此时， 出气 孔将两个腔体连通，气流从保鲜盒空腔内通过出气孔向空筒的内腔流 动， 当气体流动至两腔体压力平衡时， 由于上述推力消失， 凸缘封闭， 反复拉动活塞杆， 可对保鲜盒体进行抽真空处理， 以达到储藏食物的 要求。 当抽真空操作结束后， 上述结构还具备密封的功能， 由于保鲜 盒空腔内部气压小于外部空气气压，从而形成一个向下的压力将凸缘 向下压紧， 阻止外部空气进入保鲜盒空腔。  When in use, the piston rod is pulled outward, and the volume of the closed cavity in which the empty cylinder is separated by the plug is increased. According to physical common sense, the volume of the closed cavity is increased, so that the internal gas pressure is lowered, thereby causing the closed cavity. The difference between the air pressure and the air pressure of the crisper cavity, and the connection between the two cavities is provided with an air outlet hole, and the air pressure difference constitutes an upward thrust to the flange, since the flange is a rubber of a soft material, It is pushed up. At this time, the air outlet connects the two cavities, and the airflow flows from the cavity of the crisper through the air outlet to the inner cavity of the empty cylinder. When the gas flows to the pressure balance of the two chambers, due to the above thrust Disappeared, the flange is closed, and the piston rod is repeatedly pulled, and the fresh-keeping box can be vacuumed to meet the requirements of storing food. When the vacuuming operation is completed, the above structure also has a sealing function, because the air pressure inside the cavity of the crisper is smaller than the air pressure of the outside air, thereby forming a downward pressure to press the flange downward to prevent the outside air from entering the cavity of the crisper. .
为了方便操作， 上述活塞杆的外侧端部安装有一个手动拉环 35, 并且手动拉环 35铰链连接在活塞杆 32的外端部，当抽真空装置处于 非使用状态时， 手动拉环 35可隐藏于盖子 1上预置的凹位内。  For convenience of operation, the outer end of the piston rod is mounted with a manual pull ring 35, and the manual pull ring 35 is hingedly connected to the outer end of the piston rod 32. When the vacuuming device is not in use, the manual pull ring 35 can be Hidden in the preset recess on the cover 1.
上述的空筒可以是与盖子为整体浇铸一次成型结构，也可以是分 体式安装， 若为分体式结构， 当空筒安装于盖子内侧面时， 为了保证 其连接处的密封， 在其二者连接处套装一个橡胶套圈 36。  The above-mentioned empty cylinder may be integrally molded with the cover once or separately, or may be a split type installation. If the hollow type is installed on the inner side of the cover, in order to ensure the sealing of the joint, the two are connected. A rubber ferrule 36 is placed at the place.
根据一般的公知常识，上述抽真空装置的主要部件也可以安装在 盒体上， 具体可安装在盒体的侧壁上， 呈水平状态安装； 当然， 本实 用新型的保鲜盒可以同时安装两个或者多个上述的抽真空装置，两个 或者多个的抽真空装置可分别安装于盖子和盒体上。 According to common general knowledge, the main components of the vacuuming device can also be mounted on the casing, and can be mounted on the side wall of the casing to be installed in a horizontal state; Two or more of the above-described vacuuming devices can be installed simultaneously with the new type of crisper, and two or more vacuuming devices can be separately mounted on the cover and the casing.
另外， 如图 2所示， 上述的保鲜盒在其盖子上还设置有进气装置 4 , 包括进气孔盖 41 , 其左侧端与盖子铰链， 保鲜盒盖子上开设一个 进气孔 42 , 进气孔被进气孔盖 41遮盖， 并且在进气孔盖 41内侧面 设置用于密封的橡胶垫片 43 ; 抽真空操作进行时， 进气孔盖 41卡扣 在盖子上， 封闭进气孔 42 ; 在需要取出食物时， 打开其进气孔盖 41 , 由于外部气压大于保鲜盒空腔气压， 空气从进气孔 42进入保鲜盒内 部， 使内外气压达到平衡状态， 以顺利打开盖子。  In addition, as shown in FIG. 2, the above-mentioned crisper is further provided with an air intake device 4 on the cover thereof, and includes an air inlet cover 41, the left end of which is hinged to the cover, and an air inlet 42 is defined in the cover of the crisper. The air inlet hole is covered by the air inlet cover 41, and a rubber gasket 43 for sealing is disposed on the inner side of the air inlet cover 41. When the vacuuming operation is performed, the air inlet cover 41 is snapped on the cover to close the intake air. Hole 42; When the food needs to be taken out, the air inlet cover 41 is opened. Since the external air pressure is greater than the air pressure of the container, the air enters the inside of the crisper from the air inlet 42 to balance the internal and external air pressure to smoothly open the cover.
为了方便携带， 在上述盒体的盖子上还设置有把手。 对于本领域的技术人员来说，可根据以上描述的技术方案以及构 思，做出其它各种相应的改变以及变形， 而所有的这些改变以及变形 都应该属于本实用新型权利要求的保护范围之内。  For the convenience of carrying, a handle is also provided on the cover of the above casing. A person skilled in the art can make various other changes and modifications according to the above-described technical solutions and concepts, and all such changes and modifications should fall within the protection scope of the claims of the present invention. .
