[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A connection terminal 3 is provided on the right side of the lower housing 1, and the connection terminal 3 is a connector in the prior art. The outer side wall of the upper housing 2 is detachably installed with a U-shaped filter screen 5 through a positioning component 4. The top end of the inner side wall of the U-shaped filter screen 5 is in contact with the top end of the upper housing 2, and the bottom end of the inner side wall of the U-shaped filter screen 5 is in contact with the bottom end of the lower housing 1. By providing a U-shaped U-shaped filter screen 5, when the U-shaped filter screen 5 is installed on the surfaces of the lower housing 1 and the upper housing 2, it can press the installation positions of the lower housing 1 and the upper housing 2, and at the same time filter and block the upper air duct 7 and the lower air duct 8 to prevent dust from being adsorbed into the interior of the lower housing 1, thereby damaging the internal circuit. A lower air duct 8 is opened on the lower surface of the lower housing 1, and an upper air duct 7 is opened on the upper surface of the upper housing 2. By opening a lower air duct 8 at the bottom end of the lower housing 1 and according to the principle that hot air rises, cold air enters the interior of the lower housing 1 from the lower air duct 8 and is taken away by the hot air and discharged outward from the upper air duct 7. A guide groove is opened at the bottom end of the U-shaped filter screen 5, and an adjustable mounting mechanism 6 is detachably installed on the inner wall of the guide groove of the U-shaped filter screen 5.

[0041] Refer to Figure 4 - Figure 6The adjustable mounting mechanism 6 includes a fixed seat 601, which is slidably connected to the inner wall of the guide groove at the bottom end of the U-shaped filter 5. The fixed seat 601 moves in the guide groove at the bottom end of the U-shaped filter 5, so that the corresponding mounting foot 606 can be driven to move synchronously, so that the reserved mounting position can be adjusted according to the overall use in different positions. The outer side wall of the fixed seat 601 is fixedly connected with a fixed block 602, and the surface of the fixed block 602 is provided with an internal thread groove. The inner wall of the fixed block 602 is penetrated and threadedly connected with a threaded rod 603. When the threaded rod 603 moves on the inner wall of the fixed block 602, it will drive the contact block 604 to move synchronously with it, and the threaded rod 603 is rotatably connected to the contact block 604, so that the rotation of the threaded rod 603 will not drive the contact block 604 to rotate synchronously. The end of the threaded rod 603 is rotatably connected with the contact block 604, and the inclined surface of the contact block 604 contacts the positioning block 605. The outer side wall of the fixed seat 601 is provided with a sliding groove.

[0042] Reference Figure 5 - Figure 6 The positioning block 605 is slidably connected to the inner wall of the slide groove of the fixing seat 601, and the side wall of the fixing seat 601 is provided with a guide groove, so that the positioning block 605 as a whole can only move up and down on the side wall of the fixing seat 601, and a plurality of through holes are provided at the top of the inner wall of the guide groove of the U-shaped filter 5, and the outer wall of the top of the positioning block 605 is plugged into the through holes of the inner wall of the guide groove of the U-shaped filter 5, and the plugging between the two can fix the fixing seat 601 at multiple positions after the inner wall of the guide groove of the U-shaped filter 5 moves, so as to adjust according to the installation holes reserved for different equipment, and the inner side wall of the fixing seat 601 is rotatably connected with the mounting foot 606, and the inner wall of the mounting foot 606 is elastically connected with the plug block 608 through the return spring 607, and one end of the return spring 607 is fixedly connected to the outer wall of the plug block 608, and the other end of the return spring 607 is fixedly connected to the mounting foot 606. The inner wall of the fixing seat 601 is provided with a limiting groove, and the outer wall of the fixing seat 601 is connected with the outer wall of the fixing seat 601, and the outer wall of the fixing seat 601 is connected with the inner wall of the fixing seat 601, so that the fixing seat 601 can be fixed at multiple positions of the fixing seat 601 inner wall after the fixing seat 601 is rotated, thereby adjusting the angle of the fixing groove on the surface of the fixing seat 601 to adjust the fixing hole position reserved for different fixing positions.

[0043] Reference Figure 1 and Figure 7The positioning assembly 4 includes a protrusion 401, and the bottom end of the inner wall of the protrusion 401 is elastically connected to a pressing rod 403 through a limiting spring 402. The protrusion 401 is fixedly connected to the outer side wall of the lower shell 1, one end of the limiting spring 402 is fixedly connected to the bottom end of the outer wall of the pressing rod 403, and the other end of the limiting spring 402 is fixedly connected to the bottom end of the inner wall of the protrusion 401. The function of the limiting spring 402 is to automatically reset the position of the pressing rod 403 after being pressed and moved. The pressing rod 403 is slidably connected to the inner wall of the protrusion 401, and the wedge block 405 is slidably connected to the inner wall of the protrusion 401. The inner wall of the bottom end of the pressing rod 403 The wall is hinged with two sets of hinged rods 404, and the ends of the two sets of hinged rods 404 away from the pressing rod 403 are hinged with wedge blocks 405. The two sets of hinged rods 404 are hinged at the end of the pressing rod 403 in an inverted eight-shaped shape. By pressing the pressing rod 403, the two sets of hinged rods 404 can synchronously pull the corresponding wedge blocks 405 inward, thereby breaking away from the contact with the outer side of the U-shaped filter screen 5. The U-shaped filter screen 5 can be disassembled as a whole for cleaning. An empty groove is opened in the center of the U-shaped filter screen 5, and the outer wall of the protrusion 401 contacts the inner wall of the empty groove of the U-shaped filter screen 5, and the outer wall of the wedge block 405 contacts the surface of the U-shaped filter screen 5.

[0044] Working principle: According to the reserved installation position when using in different positions, the position of the mobile fixed seat 601 in the guide groove at the bottom end of the U-shaped filter 5 is adjusted. When the fixed seat 601 is moved to the appropriate position, the threaded rod 603 is rotated, and the threaded rod 603 moves on the inner wall thread of the fixed block 602, driving the contact block 604 to move. The contact block 604 pushes the positioning block 605 to move upward, so that the outer wall of its top end is inserted into the through hole of the inner wall of the guide groove of the U-shaped filter 5, and the position of the fixed seat 601 is fixed, thereby adjusting the horizontal position of the mounting foot 606. When it is necessary to adjust the angle of the mounting groove on the surface of the mounting foot 606, the slider 609 is moved to drive the plug block 608 to move, so that the plug block 608 is separated from the limiting groove on the inner side wall of the fixed seat 601. At this time, the mounting foot 606 can be rotated to a suitable angle, and the slider 609 is released. The reset spring 607 resets the plug block 608 and inserts it into the limiting groove to fix the position of the rotating mounting foot 606 to adapt to the mounting hole positions reserved for different installation positions.

[0045] When it is necessary to disassemble the U-shaped filter screen 5 for cleaning, press the pressing rod 403. The pressing rod 403 moves inside the inner wall of the bump 401, driving the two groups of articulated rods 404 to synchronously pull the wedge block 405 closer inward, so that the wedge block 405 is disengaged from the contact with the outer side of the U-shaped filter screen 5, and then the U-shaped filter screen 5 can be disassembled as a whole. After releasing the pressing rod 403, the limiting spring 402 makes the pressing rod 403 automatically reset to prepare for the next installation of the U-shaped filter screen 5. According to the principle that hot air rises, cold air enters the inner part of the lower housing 1 from the lower air duct 8, takes away the hot air and then discharges it from the upper air duct 7 to achieve heat dissipation. The U-shaped filter screen 5 is installed on the surface of the housing to filter and block the upper air duct 7 and the lower air duct 8, preventing dust from being adsorbed into the inner part of the lower housing 1 and avoiding damage to the internal circuits.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
