[0001] The utility model relates to the technical field of hair dryers, in particular to a hair dryer for quickly testing blood specimens in a laboratory. Background Technique

[0002] Quick test blood specimens usually refer to filter paper blood spot specimens collected from newly born neonates for quickly performing one or more clinical chemistry, immunology, biochemistry and other test items. The collection and processing methods of such specimens need to be fast and accurate. During the preparation process of quick test blood specimens, a hair dryer can effectively remove the excess moisture in the specimens, thereby preventing the growth of bacteria or molds, ensuring that the specimens are not easily decayed and producing peculiar smells, and thus extending their storage time.

[0003] Currently, in the prior art, the dry air ejected from the nozzle of the hair dryer circulates near the quick test blood specimen to remove the excess moisture contained in the quick test blood specimen. During the process of removing water from the quick test blood specimen by dry air, the quick test blood specimen itself remains stationary. When the air outlet of the hair dryer has uneven air output, there is a large difference in the dry air flow velocity at different positions of the stationary quick test blood specimen, thereby affecting the air-drying quality of the specimen.

[0004] Therefore, in view of the above problems, a hair dryer for quickly testing blood specimens in a laboratory is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 - Figure 5, the utility model provides a laboratory rapid blood specimen dryer, which includes a base 1. Above the base 1, a dryer main body 2 is installed. An outer sleeve of the air outlet of the dryer main body 2 is provided with a supporting cover 3. Near the edge of the top surface of the inner wall of the supporting cover 3, a plurality of linkage rods 31 are fixedly connected. The plurality of linkage rods 31 are equally angularly installed along the outer peripheral direction of the supporting cover 3. An annular support 4 is installed inside the supporting cover 3. An annular groove 41 is formed on the outer wall of the annular support 4. The inner wall of the annular groove 41 is respectively sleeved with the outer walls of the spherical ends of one ends of the plurality of linkage rods 31. A plurality of positioning columns 42 are fixedly connected to the top surface of the annular support 4. The plurality of positioning columns 42 are equally angularly installed along the outer peripheral direction of the annular support 4. A hollow support 5 is clamped between the plurality of positioning columns 42. A linkage assembly 6 is arranged between the supporting cover 3 and the air outlet of the dryer main body 2. The supporting cover 3 is sleeved at one end of the air outlet of the dryer main body 2, and the annular support 4 is installed through the mutual engagement between the linkage rod 31 and the annular groove 41, and can rotate relatively with the annular support 4 without mutual influence. The annular support 4 installs the hollow support 5 through the positioning columns 42. The rapid blood specimen sample is placed on the hollow support 5, so that the sample can rotate synchronously with the annular support 4 and the hollow support 5. The linkage between the air outlet of the dryer main body 2 and the supporting cover 3 is realized through the linkage assembly 6;

[0026] Such as Figure 1 , Figure 3 , Figure 4 And Figure 5As shown, the linkage component 6 includes a first rotating rod 61 and a second rotating rod 62. The first rotating rod 61 is fixedly connected to the inner wall of the supporting cover 3 through a bearing. The axis of the first rotating rod 61 coincides with the inner diameter of the supporting cover 3. Below the inner wall of the annular socket 4, an annular bevel gear 63 is fixedly connected. Symmetrically, output bevel gears 64 are fixedly connected to the outer wall of the first rotating rod 61 near the edges at both ends. Both output bevel gears 64 are engaged with the annular bevel gear 63. The second rotating rod 62 is fixedly connected to the inner diameter of the air outlet of the hair dryer main body 2 through a bearing. The axis of the second rotating rod 62 is parallel to the axis of the first rotating rod 61. At the center of the outer walls of the first rotating rod 61 and the second rotating rod 62, chain wheels 65 are fixedly connected. A chain 66 is installed between the outer walls of the two chain wheels 65. Near the edges at both ends of the outer wall of the second rotating rod 62, fan blades 67 are fixedly connected. The first rotating rod 61 and the second rotating rod 62 are respectively fixed between the supporting cover 3 and the air outlet of the hair dryer main body 2 through bearings. When the hair dryer main body 2 discharges dry air, the airflow drives the fan blades 67 to rotate, thereby driving the overall rotation of the second rotating rod 62. The first rotating rod 61 and the second rotating rod 62 are connected by the chain wheels 65 and the chain 66, which makes the first rotating rod 61 and the second rotating rod 62 rotate in linkage. After the first rotating rod 61 rotates, since it is engaged with the annular bevel gear 63 under the annular socket 4 through the output bevel gear 64, a rotational output force is provided for the annular socket 4 and the hollow socket 5 to control the rotation of the sample test tube on the hollow socket 5;

[0027] As Figure 1 and Figure 2 shown, a supporting ring 21 is fixedly connected to the outer wall of the air outlet of the hair dryer main body 2. The top surface of the supporting ring 21 contacts the bottom surface of the supporting cover 3. Below the outer wall of the supporting cover 3, a plurality of support rods 7 are installed. One end of one of the support rods 7 is fixedly connected to the outer wall of the hair dryer main body 2, and the other ends of the plurality of support rods 7 are perpendicularly fixedly connected to the top surface of the base 1. The support rods 7 increase the installation stability of the supporting cover 3 through the mutual cooperation between the base 1 and the outer wall of the hair dryer main body 2, and the supporting ring 21 can limit the lower position of the supporting cover 3;

[0028] Working principle: The supporting cover 3 is sleeved on one end of the air outlet of the air dryer main body 2. The supporting rod 7 increases the installation stability of the supporting cover 3 through the mutual cooperation between the base 1 and the outer wall of the air dryer main body 2. The supporting ring 21 can limit the lower position of the supporting cover 3. The supporting cover 3 is installed on the annular support seat 4 through the mutual engagement between the linkage rod 31 and the annular groove 41, and can rotate relatively with the annular support seat 4 without affecting each other. The annular support seat 4 is installed on the hollow support seat 5 through the positioning column 42. The quick-test blood specimen sample is placed on the hollow support seat 5, which enables the sample to rotate synchronously with the annular support seat 4 and the hollow support seat 5. The linkage between the air outlet of the air dryer main body 2 and the supporting cover 3 is realized through the linkage assembly 6. The first rotating rod 61 and the second rotating rod 62 are respectively fixed between the supporting cover 3 and the air outlet of the air dryer main body 2 through bearings. When the air dryer main body 2 discharges dry air, the air flow drives the fan blade 67 to rotate, and then drives the overall rotation of the second rotating rod 62. The first rotating rod 61 and the second rotating rod 62 are connected by a sprocket 65 and a chain 66, which enables the first rotating rod 61 and the second rotating rod 62 to rotate in linkage. After the first rotating rod 61 rotates, since it engages with the lower annular bevel gear 63 of the annular support seat 4 through the output bevel gear 64, it provides a rotational output force for the annular support seat 4 and the hollow support seat 5 to control the rotation of the sample test tube on the hollow support seat 5.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
