Description

Technical Field

[0001] The utility model belongs to the technical field of water bath nitrogen blowing instrument, and particularly relates to a water pumping device of a water bath nitrogen blowing instrument. Background Art

[0002] The water bath nitrogen blowing instrument concentrates the sample by blowing nitrogen into the heated sample surface, shortening the analysis time and meeting the needs of rapid detection.

[0003] The water bath nitrogen blowing instrument comprises a water pumping component and a plurality of injection tubes. Water is allowed to enter the plurality of injection tubes through the water pumping component, and the water is allowed to enter the interior of the reagent tube through the injection tubes for treatment.

[0004] However, water is allowed to enter the reagent tube through multiple injection tubes, but some of the injection tubes cannot be used. In the prior art, a manual adjustment mechanism, such as a control valve, is used to manually rotate the control valve to open and close the water pipe on the pumping assembly. Although this is simple, when multiple injection tubes need to be used, they need to be rotated and adjusted one by one, which is not only time-consuming and labor-intensive, but also increases financial investment.

[0005] In the prior art, when installing the reagent tube, it is necessary to adjust the height of the injection tube (because the length of the injection tube is greater than the length of the reagent tube, the injection tube will block the reagent tube when installing the reagent tube and needs to be adjusted). The general method requires manual adjustment, and the manual adjustment method is to manually rotate the threaded rod so that the threaded rod drives the injection tube to move for adjustment. This adjustment method requires frequent rotation, which is time-consuming and labor-intensive. At the same time, the electrical components are adjusted, and the injection tube is moved by the electric telescopic rod. Although the operation is simple, it increases financial investment.

[0006] To this end, we proposed a water-bath nitrogen blowdown apparatus pumping device, which not only does not require manual adjustment of the open conical injection tube, thus saving time and effort, but also facilitates the installation of reagent tubes, is simple to operate, saves manpower, and reduces financial investment. Utility Model Content

[0007] The purpose of the utility model is to provide a water-bath nitrogen blowing instrument water pumping device, which not only does not require manual adjustment of the opened conical injection tube, thereby achieving the effect of saving time and labor, but also can facilitate the installation of reagent tubes, is simple to operate, saves manpower, and reduces financial investment.

[0008] The technical solutions adopted in this utility are as follows:

[0009] A water-bath nitrogen blowing instrument water pumping device, comprising a water-bath nitrogen blowing instrument body, wherein the water-bath nitrogen blowing instrument body is provided with a water pumping component and a plurality of hollow bearing shells;

[0012] Furthermore, the pumping assembly includes a pumping pipe arranged inside the water bath nitrogen blowing instrument body, a water guide pipe is installed on the top of the pumping pipe, a water pump is arranged on the water guide pipe, and the top of the water guide pipe is connected to the water collecting plate.

[0013] Furthermore, the hollow bearing shell is provided with a through hole.

[0014] Furthermore, a spherical groove is provided on the bearing plate.

[0015] Furthermore, the conical injection tube is divided into two parts, namely a connecting section and an injection section. The injection section is movably arranged inside the connecting section. A conical sealing block is movably arranged on the inner wall of the connecting section.

[0027] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0028] like Figure 1-5 As shown, the technical solution adopted by the present invention is as follows: a water-bath nitrogen blowing instrument water pumping device, comprising a water-bath nitrogen blowing instrument body 1, on which a water pumping assembly and a plurality of hollow bearing shells 2 are arranged;

[0029] A water collecting plate 3 is provided on the pumping assembly, and a plurality of connecting pipes 4 are installed at one end of the water collecting plate 3 away from the pumping assembly, each connecting pipe 4 has two corners, and a sealing plug 5 matching the inner cavity is provided at one corner of each connecting pipe 4, and the sealing plug 5 matches the water guide cavity of the connecting pipe 4, so that the connecting pipe 4 can be sealed or opened by the sealing plug 5, which is the same as the rubber piston in the prior art, and a conical injection tube 6 is installed at one end of each connecting pipe 4 away from the water collecting plate 3;

[0030] An elastic component is arranged inside the hollow carrying shell 2, a carrying plate 8 is installed on the top of the elastic component, a reagent tube is arranged on the top of the carrying plate 8, and an L-shaped moving rod 9 is arranged on one side of the carrying plate 8. The top of the L-shaped moving rod 9 passes through a connecting tube 4 and is connected to a sealing plug 5.

[0031] The working principle is as follows: first, place the reagent tube on the supporting plate 8. The reagent tube has a certain weight, so that the supporting plate 8 drives the elastic component to move, and at the same time, the supporting plate 8 drives the L-shaped moving rod 9 to move the sealing plug 5, so that the water guide channel of the connecting tube 4 is opened, and then the water is allowed to pass through the water collecting plate 3 and the connecting tube 4 into the conical injection tube 6 through the pumping assembly, and then enters the inside of the reagent tube for processing. Compared with the existing device, this device does not require manual adjustment of the opened conical injection tube 6, thereby achieving the effect of saving time and labor.

[0032] In order to enable the reagent tube to be installed on the carrier plate 8, a through hole is opened on the hollow carrier shell 2, and the reagent tube is fixed on the carrier inside the hollow carrier shell 2 through the through hole.

[0033] At the same time, in order to ensure that the reagent tube can be fixed, a spherical groove is opened on the carrying plate 8, and the bottom of the reagent tube can be installed and fixed through the spherical groove.

[0034] It should be noted that a deformable and compressible rubber layer is provided on the inner wall of the through hole. The rubber layer can not only increase the friction to prevent shaking, but also can install reagent tubes of different sizes according to the characteristics of the rubber layer (deformation and compression), thereby increasing the practicality of the device.

[0035] In this embodiment, the L-shaped moving rod 9 can move up and down. In order to enable it to move on the hollow load-bearing shell 2, a sliding groove is opened on one side of the hollow load-bearing shell 2, and the L-shaped moving rod 9 is arranged inside the sliding groove, so that the L-shaped moving rod 9 can move on the hollow load-bearing shell 2, and the L-shaped moving rod 9 drives the sealing plug 5 to move.

[0036] Among them, the L-shaped moving rod 9 is provided with sealing members at the upper and lower positions passing through the connecting pipe 4. The sealing member can be an elastic sealing sleeve made of rubber, so that the upper and lower positions passing through can be sealed when moving up and down to prevent water leakage.

[0037] It should be noted that the seal is not shown in the figure and belongs to the prior art, so no further elaboration will be made here.

[0038] like Figure 5 As shown, the conical injection tube 6 is divided into two parts, namely a connecting section 13 and an injection section 14. The injection section 14 is movably arranged inside the connecting section 13, and a conical sealing block 15 is movably arranged on the inner wall of the connecting section 13. The bottom of the conical sealing block 15 is connected to the injection section 14 located inside the connecting section 13. The advantage of such a setting is that the injection section 14 can be movably extended and retracted inside the connecting section 13, so as to facilitate the installation of the reagent tube without the need for manual adjustment or the up and down movement of electrical components such as an electric telescopic rod. This not only simplifies the operation and saves manpower, but also reduces financial investment.

[0039] In the prior art, when installing the reagent tube, it is necessary to adjust the height of the injection tube (because the length of the injection tube is greater than the length of the reagent tube, the injection tube will block the reagent tube when installing the reagent tube and needs to be adjusted). The general method requires manual adjustment, and the manual adjustment method is to manually rotate the threaded rod so that the threaded rod drives the injection tube to move for adjustment. This adjustment method requires frequent rotation, which is time-consuming and labor-intensive. At the same time, the electrical components are adjusted, and the injection tube is moved by the electric telescopic rod. Although the operation is simple, it increases financial investment.

[0040] A guide hole is provided on the conical sealing block 15, through which water can flow in the conical injection tube 6, thereby performing injection molding.

[0041] like Figure 2 and Figure 3 As shown, the pumping assembly includes a pumping pipe arranged inside the water bath nitrogen blowing instrument body 1, a water pipe 11 is installed on the top of the pumping pipe, a water pump 12 is arranged on the water pipe 11, and the top of the water pipe 11 is connected to the water collecting plate 3. The water pump 12 provides power to make the water inside the water bath nitrogen blowing instrument body 1 enter the water collecting plate 3 through the water pipe 11, thereby achieving the effect of pumping water.

[0042] like Figure 4 As shown, the elastic component includes a hollow cylinder 16 arranged inside the hollow supporting shell 2, a spring 17 is arranged inside the hollow cylinder 16, a piston disk 18 is installed on the top of the spring 17, a connecting rod 19 is arranged on the top of the piston disk 18, the top of the connecting rod 19 passes through the hollow cylinder 16 and is connected to the supporting plate 8. When subjected to the gravity of the reagent tube, the supporting plate 8 drives the connecting rod 19 to make the piston disk 18 squeeze the spring 17, so that the L-shaped moving rod 9 can move. When not subjected to gravity, the elasticity of the spring 17 restores the supporting plate 8 to its original position, so that the L-shaped moving rod 9 drives the sealing plug 5 to return to its original position for sealing.

[0043] This arrangement can prevent water from flowing out of those unused conical injection tubes 6, thereby making it convenient for people to use.

[0044] The working principle of the utility model is as follows: firstly, the reagent tube is placed on the supporting plate 8, and the reagent tube has a certain weight, so that the supporting plate 8 drives the elastic component to move, and at the same time, the supporting plate 8 drives the L-shaped moving rod 9 to move the sealing plug 5, so that the water guide channel of the connecting tube 4 is opened, and then the water is allowed to pass through the water collecting plate 3 and the connecting tube 4 into the conical injection tube 6 through the pumping component, and then enters the inside of the reagent tube for processing. Compared with the existing device, there is no need for manual adjustment to open the conical injection tube 6, so as to achieve the effect of saving time and labor. At the same time, the injection section 14 can be movable and retracted inside the connecting section 13, so as to facilitate the installation of the reagent tube, without the need for frequent manual adjustment, or the electrical components such as the electric telescopic rod to move up and down. This is not only simple to operate and saves manpower, but also reduces financial investment.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
