Detailed Description

Example 1

Referring to fig. 1 to 4, the blood specimen submission apparatus of the present invention includes a specimen accommodation unit 400, an ice crushing unit 300, and an ice cube accommodation unit 200, which are sequentially arranged from bottom to top, wherein a specimen container 401 is placed inside the specimen accommodation unit 400, and the ice cube accommodation unit 200 accommodates a large ice cube 203, and then the large ice cube 203 can be gradually crushed by the ice crushing unit 300, and the crushed ice is introduced and supplemented into the specimen accommodation unit 400, so that the specimen accommodation unit 400 maintains the presence of an ice-water mixture at all times.

Specifically, the ice crushing unit 300 is provided with an ice crushing blade 301 for gradually crushing the ice pieces 203 contained in the ice containing unit 200 by the ice crushing blade 301, the ice crushing blade 301 adopts a rotary ice crushing mode, the ice crushing blade 301 is connected with the driving motor 600 through a transmission mechanism, and then the ice crushing blade 301 is driven to rotate by the driving motor 600, and the rotation speed is determined according to the melting speed of the crushed ice. In this embodiment, the ice crushing blade 301 is a blade holder having a circular revolving structure, the upper end surface of the blade holder is provided with a plurality of ice crushing blades 301 along the radial direction, and the ice storage unit 200 is located above the ice crushing unit 300, so that the bottom of the ice 203 can be crushed by the ice crushing blades 301 when the ice crushing blades 301 rotate.

In order to ensure that the crushed ice can accurately enter the designated position of the specimen accommodation unit 400 below, the middle of the ice crushing blade 301 is further provided with a plurality of ice-ejecting grooves 302, so that the crushed ice can be collected into the ice-ejecting grooves 302 and then enters the specimen accommodation unit 400 from the ice-ejecting grooves 302, and the crushed ice is not wasted excessively.

The ice block accommodating unit 200 comprises an ice block support 201, the ice block support 201 is of a conical cavity structure, one end of the small diameter of the ice block support 201 is in contact with the ice crushing blade 301, and a plurality of independent supporting air bags 202 are arranged on the inner ring of the ice block support 201. Because ice cube support 201 adopts the cone cavity structure, ice cube 203 wherein also is the structure of its adaptation, relies on the weight of ice cube 203 self on the one hand like this, can laminate comparatively closely between ice cube 203 and the ice cube support 201, guarantees that the ice chopper 301 can keep the trash ice state, if not cone structure, the ice cube 203 just takes place the slope easily, and the trash ice chopper 301 is difficult to realize regular trash ice, and the trash ice effect is not very good yet.

When the ice 203 is light, the ice crushing process of the ice crushing blade 301 may be difficult to be performed, and the ice is easily thrown, so the pressing unit 100 is further disposed above the ice containing unit 200, the pressing unit 100 includes the airbag portion housing 101 and the inflatable airbag 102, the inflatable airbag 102 includes the air equalizing partition 103, the air equalizing partition 103 divides the inflatable airbag 102 into a first airbag body and a second airbag body, the first airbag body is embedded in the airbag portion housing 101, the second airbag body is used for pressing the ice 203 of the ice containing unit 200 after being inflated, and the air inlet of the inflatable airbag 102 is located on the first airbag body. The inflatable air bag 102 presses the large-diameter end of the ice 203 upward, so that the small-diameter end of the ice 203 can be constantly in contact with the ice crusher 301, and the ice crushing effect is better. In addition, in the later stage, when the ice 203 melts to a certain extent and the self weight is insufficient, the pressing force is also applied, and the ice 203 may be crushed for a long time.

By the support of the support airbag 202 and the extrusion of the top inflatable airbag 102, a flexible support is formed around the ice 203, so that the ice crushing blade 301 is not easy to crack the whole ice 203 when crushing the ice, and once the ice 203 is cracked, the ice crushing effect is not good. If the hard support is adopted on the periphery or the top, the hard support is easy to be opposite to the hard support of the ice crushing blade 301, and the ice blocks 203 are easy to break, thereby affecting the ice crushing effect.

The middle of the inflatable air bag 102 is provided with the air equalizing partition plate 103, so that air entering from a single air inlet can be ensured to be filled in the first air bag body firstly, then the air enters the second air bag body through the air equalizing partition plate 103, the second air bag body extrudes the ice blocks 203 more uniformly, the ice blocks 203 are prevented from inclining due to over-concentrated extrusion force, and the ice crushing effect of the ice crushing knife 301 is not ideal after the ice blocks 203 incline.

The inflatable bladder 102 is connected to a blower 105 through a detachable pipe 104, the blower 105 is connected to a driving motor 600 through a transmission mechanism, and the pressing unit 100 can be rotated to open and close with respect to one side of the ice containing unit 200 in this embodiment. Therefore, the addition of the ice blocks 203 is convenient, when the ice blocks 203 need to be added, the overturning of the extrusion unit 100 can be realized only by detaching the detachable pipeline 104 and the air inlets of the inflatable air bags 102, the addition of the ice blocks 203 is realized, and the operation is simple and convenient.

Referring to fig. 5-6, the present invention is further provided with a tray assembly 700 for freezing water into ice, the tray assembly 700 being dedicated to the frozen ice pieces 203 for placement in a freezing apparatus. The tray assembly 700 comprises a first tray 701 and a second tray 702, an open cavity capable of containing the ice cube support 201 is formed in the middle of the first tray 701, the ice cube support 201 can contact one end of the large diameter of the ice cube support with the bottom of the open cavity and is placed in the first tray 701, the second tray 702 is provided with an extension part 703 for filling a gap between the ice cube support 201 and the first tray 701, the second tray 702 can cover the first tray 701, and a water injection hole 704 is formed in the second tray 702. Water can be injected into the water injection hole 704, and then the water injection hole is placed in a freezing device, such as a freezer and a refrigerator, and can be taken out for use after being frozen. When taking out, the tray assembly 700 is turned upside down, the first tray 701 is positioned above, the second tray 702 is positioned below, and the first tray 701 is taken out, so that the ice cube support 201 can be conveniently taken out from the second tray 702.
