DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5The sample concentrator shown is easy to clean, including an instrument body 1, two lifting grooves are provided at the bottom of the instrument body 1, and lifting plates 3 are slidably installed in the two lifting grooves. The two lifting plates 3 are connected by a control component, and the four sides of the two lifting plates 3 are provided with sealing components. A telescopic groove is provided on the inner wall of the side of the instrument body 1, and an electric telescopic rod 8 is fixedly installed on the inner wall of the side of the telescopic rod. An I-shaped plate 9 is fixedly installed on the output end of the electric telescopic rod 8, and a cleaning component is arranged on the I-shaped plate 9. The I-shaped plate 9 is adapted to the instrument body 1, and a circular hole is provided on the inner wall of the other side of the instrument body 1, and a dust removal component is arranged in the circular hole. A dust collecting box 17 is fixedly installed on the side of the instrument body 1, and the dust collecting box 17 is connected to the circular hole.

[0024] With the help of the above structure, when it is necessary to clean the inside of the instrument body 1, first put the instrument in a closed state, and then drive the two lifting plates 3 to move downward synchronously through the control component, so that the telescopic slot, the inside of the instrument body 1, the circular hole, and the dust box 17 are in a connected state, start the electric telescopic rod 8 to drive the I-shaped plate 9 to move horizontally, and clean the inner wall of the instrument body 1 through the cleaning component, and at the same time, the dust inside the instrument body 1 is adsorbed through the dust removal component, and it is collected in the dust box 17. This arrangement not only has a good dust removal effect, but also can realize the cleaning function of the inner wall, thereby improving the cleaning effect.

[0025] like Figure 1 As shown, a sealing cover plate 2 is hingedly installed on the top of the instrument body 1, and a pull ring is fixedly installed on the top of the sealing cover plate 2. With this arrangement, the sealing cover plate 2 can be opened and closed conveniently by the pull ring, which is more labor-saving.

[0026] Specifically, by setting the sealing cover 2, the sealing function of the instrument body 1 can be achieved, so that the interior is in a sealed state, which is convenient for concentration, cleaning and other operations, and by setting a pull ring on the top, it can be more convenient during the opening and closing process and convenient for actual use.

[0027] like Figure 3 As shown, the control component includes a connecting plate 5, and the side inner walls of the two lifting grooves close to each other are jointly provided with a connecting hole, and the relative inner walls of the connecting hole are jointly rotatably installed with a screw rod 6, and the bottom inner wall of the connecting hole is provided with a motor groove, and a lifting motor 7 is fixedly installed in the motor groove, and the output shaft of the lifting motor 7 is connected to the bottom end of the screw rod 6, and the connecting plate 5 is threadedly installed on the screw rod 6, and the top of the connecting plate 5 is fixedly connected to the bottom of the two lifting plates 3. The advantage of this arrangement is that through the arrangement of the screw rod 6 and the connecting plate 5, the two lifting plates 3 can be driven to rise and fall synchronously.

[0028] Specifically, the lifting motor 7 is started to drive the screw 6 to rotate, and then the connecting plate 5 is driven to achieve lifting movement under the action of the thread. Since the connecting plate 5 is fixedly connected to the two lifting plates 3, the movement of the connecting plate 5 drives the two lifting plates 5 to move synchronously at the same time, so as to achieve sealing of the inside of the instrument body 1.

[0029] like Figure 3 As shown, the sealing assembly includes four sealing gaskets 4, and the four sealing gaskets 4 are respectively fixedly installed on the four sides of the lifting plate 3. The advantage of such an arrangement is that, through the arrangement of the four sealing gaskets 4, when the lifting plate 3 moves upward to the top, a sealing function can be achieved through multiple sealing gaskets 4 to prevent dust from floating into the interior of the instrument body 1.

[0030] Specifically, when the lifting plate 3 moves upward to the top, the four sides of the lifting plate 3 can be sealed through the sealing function of the four sealing pads 4, so that the interior of the instrument body 1 is in a closed state, preventing dust from floating in from the telescopic slot or the dust box 17.

[0031] like Figure 3 As shown, the cleaning assembly includes two cleaning cottons 10 and a cleaning cloth 11. The two cleaning cottons 10 are respectively fixedly mounted on the two side portions of the I-shaped plate 9, and the cleaning cloth 11 is fixedly mounted on the bottom inner wall of the I-shaped plate 9. The advantage of such an arrangement is that, through the arrangement of the two cleaning cottons 10 and the cleaning cloth 11, when the I-shaped plate 9 moves, the two side inner walls and the bottom inner wall of the instrument body 1 can be cleaned through the two cleaning cottons 10 and the cleaning cloth 11.

[0032] Specifically, when the electric telescopic rod 8 is started, the electric telescopic rod 8 drives the I-shaped plate 9 to move horizontally, and drives the two cleaning cottons 10 and the cleaning cloth 11 to move horizontally synchronously. Since the two cleaning cottons 10 are in contact with the relative inner walls of the instrument body 1 respectively, the relative inner walls of the instrument body 1 can be cleaned by the two cleaning cottons 10, and at the same time, the bottom inner wall of the instrument body 1 can be synchronously cleaned by the cleaning cloth 11, and the cleaning effect is better.

[0033] like Figure 5 As shown, the dust removal assembly includes a mounting plate 13, which is fixedly mounted on the inner wall of the circumferential side of the circular hole, and a dust removal motor 14 is fixedly mounted on the side of the mounting plate 13. The output shaft of the dust removal motor 14 extends to the outside of the mounting plate 13 and is fixedly sleeved with a dust removal fan 15 and a cleaning brush 16. A circular filter plate 12 is fixedly mounted on the inner wall of the circumferential side of the circular hole, and the cleaning brush 16 is fitted with the circular filter plate 12. The advantage of such an arrangement is that, through the arrangement of the dust removal motor 14 and the dust removal fan 15, dust removal operations can be performed on the inside of the instrument body 1.

[0034] Specifically, the dust removal motor 14 is started to drive the dust removal fan 15 to rotate, and the wind force generated by the dust removal fan 15 is used to remove the dust in the instrument body 1. When dust adheres to the circular filter plate 12, the cleaning brush 16 is driven by the dust removal motor 14 to rotate synchronously and clean the circular filter plate 12, so that the dust adhered to the circular filter plate 12 is collected in the dust box 17.

[0035] like Figure 4 As shown, a collecting groove is provided on the side of the dust box 17, and a collecting drawer 18 is slidably installed in the collecting groove. The advantage of such an arrangement is that the dust in the dust box 17 can be quickly cleaned through the arrangement of the collecting drawer 18.

[0036] Specifically, when the dust in the dust box 17 needs to be quickly cleaned, the cleaning operation can be achieved by pulling the collection drawer 18, which is convenient to use and highly practical.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
