Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sample storage, and in particular relates to a test sample storage cabinet. Background Art
[0002] Food inspection samples typically need to be stored in a refrigerator at 4°C and tested within 36 hours to prevent sample deterioration and microbial growth. Due to the risk of cross-contamination between microorganisms in individual samples, individual samples must be stored separately. Multi-drawer storage cabinets feature multiple, relatively closed storage chambers that can be opened individually and maintained throughout the entire cabinet.
[0003] A refrigeration compressor is installed inside the multi-drawer storage cabinet to generate cold air. It is connected to the internal cold air cavity with a blower. When the blower is running, the cold air can be transported to the outside of each storage cavity to achieve cooling.
[0004] When the samples to be tested are stored, they are placed separately in different storage chambers and separated from each other. The samples in the glass dishes often have a certain temperature. The temperature in the storage chamber is generally lower than 4°C, which causes the hot gas volatilized by the samples to condense when it encounters cold, forming water droplets on the upper wall of the storage chamber. The water droplets dripping onto the samples can easily cause contamination. For this reason, we propose a test sample storage cabinet. Utility Model Content
[0005] The utility model aims to provide a test sample storage cabinet, which absorbs condensed water droplets, reduces the occurrence of water droplets falling on samples and causing contamination, and then drains the water to the outside of the storage cavity and removes the moisture through cold wind.
[0006] The technical solutions adopted by this utility model are as follows:
[0007] A test sample storage cabinet comprises a cabinet body, wherein a plurality of lockable drawers are inserted at intervals on the front side of the cabinet body, a water control slope is fixed inside the cabinet body directly above the lockable drawers, and absorbent felt is fixed on the inclined surface of the water control slope, and strip holes are opened inside the cabinet body at the lower edge of the water control slope, and one end of the absorbent felt passes through the adjacent strip holes and hangs down toward the inside of the cabinet body. When the sample is to be inspected, the lockable drawer is opened with a key, and a glass dish containing the sample is placed in it, and then the lockable drawer is closed. The internal refrigeration compressor blows cold air to cool down each lockable drawer. Once the hot air from the sample rises and condenses into water droplets when it encounters the colder upper wall of the cabinet body, the absorbent felt is used to absorb the condensed water droplets, thereby reducing the contamination caused by water droplets falling on the sample, and then the water is drained to the outside of the storage cavity along the strip holes. Since the capillary absorbent fibers facilitate water absorption and volatilization, the water on the absorbent felt is taken away by the cold air, thereby reducing the water accumulated in the storage cavity.
[0008] A cold air cavity connected to the strip hole is provided on the back of the cabinet, and the drooping end of the absorbent felt extends into the cold air cavity. The cold air cavity is used to circulate cold air after the refrigeration compressor absorbs heat. The cold air cavity partially surrounds the storage cavity, and the drooping part of the absorbent felt can evaporate moisture into the cold air, so that the water droplets in the storage cavity diffuse into the cold air cavity along the humidity gradient and gradually evaporate.
[0009] Ice silk felt is sewn and installed on the lower edge of the absorbent felt. One side of the ice silk felt is fixedly connected to the inner wall of the cold air cavity. The dry ice silk felt is used to absorb part of the moisture on the absorbent felt, thereby increasing the volatilization area and dissipating the moisture into the cold air more quickly.
[0010] A flip cover is horizontally hinged on one side of the cold air chamber above the strip hole, and the lower edge of the flip cover falls below the adjacent strip hole to control the downward flipping angle of the flip cover. The flip cover can partially cover the strip hole and the opening degree of the strip hole can be adjusted to minimize the cold air flowing into the storage chamber along the strip hole, thereby maintaining the relative airtightness of the sample storage environment.
[0011] A number of limit rods are distributed along a vertical array inside the cold air chamber, and the outer sides of the limit rods are fixedly connected to the lower edges of adjacent flaps. The rear door of the cabinet can be opened, and the limit rods and the corresponding flaps can be raised by hand to increase the ventilation surface of the strip holes. Conversely, the limit rods and the corresponding flaps can be lowered to reduce the ventilation surface of the strip holes.
[0012] Both ends of the limit rod are threadedly installed with external friction sleeves, and the end faces of the external friction sleeves are parallel to one side of the cold air chamber. The external friction sleeves are rotated forward along the thread until they are close to the inner wall of the cabinet, and the limit rod is locked by utilizing the friction in the vertical direction to stably support the flip cover. Conversely, the external friction sleeves are reversed along the thread to detach from the inner wall of the cabinet to release the locked state.
[0013] The technical effects achieved by this utility model are:
[0014] The utility model provides a test sample storage cabinet. When a sample is to be tested, a key is used to open a locked drawer, a glass dish containing the sample is placed in it, and then the locked drawer is closed. An internal refrigeration compressor blows cold air to cool down each locked drawer. Once the hot air from the sample rises and condenses into water droplets when it encounters the colder upper wall of the cabinet, absorbent felt is used to absorb the condensed water droplets, thereby reducing the contamination caused by the water droplets falling on the sample. The water is then drained to the outside of the storage cavity along the strip holes. Since the capillary absorbent fibers facilitate water absorption and volatilization, the water on the absorbent felt is taken away by the cold air, thereby reducing the water accumulated in the storage cavity.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0023] Example 1:
[0024] like Figure 1-2 As shown, a test sample storage cabinet includes a cabinet body 1, and a refrigeration compressor is fixed on the back of the cabinet body 1. This technical solution is a prior art and is not shown in the figure. A plurality of lockable drawers 2 are inserted at intervals on the front of the cabinet body 1. Water control slopes 3 are fixed just above the lockable drawers 2 inside the cabinet body 1. The inclined surfaces of the water control slopes 3 are fixed with absorbent felts 4. The absorbent felts 4 can be made of capillary absorbent fiber material. Strip holes 5 are opened at the lower edge of the water control slopes 3 inside the cabinet body 1. One end of the absorbent felts 4 passes through the adjacent strip holes 5 and hangs down toward the inside of the cabinet body 1. After food inspection sampling, the samples are separately Place the sample in a glass dish. When the sample is to be tested, use the key to open the locked drawer 2, put the glass dish containing the sample in, and then close the locked drawer 2. The internal refrigeration compressor will blow cold air to cool down each locked drawer 2. Once the hot air from the sample rises and condenses into water droplets on the cooler upper wall of the cabinet 1, the absorbent felt 4 will be used to absorb the condensed water droplets to reduce the contamination caused by water droplets falling on the sample. The water will then be drained to the outside of the storage cavity along the strip holes 5. Since the capillary absorbent fibers facilitate water absorption and volatilization, the water on the absorbent felt 4 will be taken away by the cold air, reducing the water accumulated in the storage cavity.
[0025] For the refrigeration compressor, you can refer to the Chinese utility model with publication number CN220303995U, which is a sample storage cabinet for the laboratory. An air head and a return air pipe can be selected, in which the return air pipe bypasses the storage cavity where each locked drawer 2 is located, and is used to guide cold air to surround each locked drawer 2 in turn, so as to conveniently take away the heat from the storage cavity and keep the sample temperature within the range of 0 to 4°C, so that it can be refrigerated for a long time.
[0026] like Figure 1 and Figure 2 As shown, a cold air cavity 6 connected to the strip hole 5 is opened on the back of the cabinet 1, and the drooping end of the water-absorbing felt 4 is inserted into the cold air cavity 6. The cold air cavity 6 is used to circulate the cold air after the refrigeration compressor absorbs heat. The cold air cavity 6 partially surrounds the storage cavity, and the drooping part of the water-absorbing felt 4 can evaporate moisture into the cold air, so that the water droplets in the storage cavity diffuse into the cold air cavity 6 along the humidity gradient and gradually evaporate.
[0027] like Figure 1 and Figure 2 As shown, ice silk felt 7 is sewn and installed on the lower edge of the water-absorbing felt 4. The ice silk felt 7 also has a certain capillary effect and a relatively large evaporation surface. One side of the ice silk felt 7 is fixedly connected to the inner wall of the cold air chamber 6. The dry ice silk felt 7 absorbs part of the moisture on the water-absorbing felt 4, increases the evaporation area, and dissipates the moisture into the cold air more quickly.
[0028] The working principle of the present invention is as follows: when a sample is to be inspected, a key is used to open the locked drawer 2, a glass dish containing the sample is placed in it, and then the locked drawer 2 is closed. The internal refrigeration compressor blows cold air to cool down each locked drawer 2. Once the hot air from the sample rises and condenses into water droplets on the cooler upper wall of the cabinet 1, the absorbent felt 4 is used to absorb the condensed water droplets, reducing the contamination caused by water droplets falling on the sample. The water is then drained to the outside of the storage cavity along the strip holes 5. Since the capillary absorbent fibers facilitate water absorption and volatilization, the water on the absorbent felt 4 is taken away by the cold air, reducing the water accumulated in the storage cavity.
[0029] Example 2:
[0030] like Figure 3-5 As shown, it is basically the same as Example 1, and the similarities can be referred to Example 1. In order to prevent cold air from entering the storage cavity, it is characterized in that: a flip cover 8 is horizontally hinged at a position above the strip hole 5 on one side of the cold air cavity 6, and the upper edge of the flip cover 8 is hinged to one side of the cold air cavity 6, and the lower edge of the flip cover 8 falls below the adjacent strip hole 5, controlling the downward flip angle of the flip cover 8. The flip cover 8 can partially cover the strip hole 5, and the opening degree of the strip hole 5 can be adjusted to minimize the cold air entering the storage cavity along the strip hole 5, thereby maintaining the relative airtightness of the sample storage environment.
[0031] like Figure 3 and Figure 4As shown, a number of limit rods 9 are distributed along the vertical array inside the cold air chamber 6. The outer sides of the limit rods 9 are fixedly connected to the lower edges of the adjacent flaps 8. The rear door of the cabinet 1 can be opened. By raising the limit rods 9 and the corresponding flaps 8 by hand, the ventilation surface of the strip holes 5 can be increased. Conversely, by lowering the limit rods 9 and the corresponding flaps 8, the ventilation surface of the strip holes 5 can be reduced. After the adjustment is completed, the rear door is closed.
[0032] like Figure 3 、 Figure 4 and Figure 5 As shown, both ends of the limit rod 9 are threadedly installed with an outer friction sleeve 10, and the end faces of the outer friction sleeve 10 are parallel to one side of the cold air chamber 6. The outer friction sleeve 10 is rotated forward along the thread until it is pressed against the inner wall of the cabinet 1. The limit rod 9 is locked by the friction effect in the vertical direction to stably support the flip cover 8. Conversely, the outer friction sleeve 10 is reversed along the thread to detach from the inner wall of the cabinet 1 to release the locked state.
[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
