[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0037] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0038] According to the embodiments of the present utility model, Figures 1 to 3 As shown, a device host is provided, including a shell 1, a fan assembly 2 and a dustproof assembly 3. The interior of the shell 1 is a cavity, which is suitable for installing a board module 106. An air inlet 101 and an air outlet 102 are provided on the side of the shell 1. The air inlet 101 and the air outlet 102 are arranged opposite to each other. The board module 106 is located between the air inlet 101 and the air outlet 102. The fan assembly 2 is arranged inside the shell 1, suitable for inputting air into the shell 1 from the air inlet 101 and outputting air to the outside of the shell 1 from the air outlet 102. The dustproof assembly 3 is detachably connected to the shell 1, located at the air inlet 101, and suitable for filtering dust in the air entering the air inlet 101.

[0039] Specifically, the device host in this embodiment is the host of an ultrasonic device. The internal cavity of the shell 1 is suitable for installing a board module 106. The board module 106 generates heat during operation. The shell 1 is rectangular. On the side of the shell 1, an air inlet 101 and an air outlet 102 are symmetrically arranged so that air convection can bring the heat inside the shell 1 out of the shell 1, thereby reducing the temperature inside the shell 1. A fan assembly 2 is arranged inside the shell 1 for inputting external air into the shell 1 and / or outputting the air inside the shell 1 to the external environment. A dustproof assembly 3 is detachably installed at the air inlet 101 to filter dust and impurities in the air entering the shell 1, so that dust can be filtered on the dustproof assembly 3 to keep the inside of the shell 1 clean and reduce the accumulation of dust inside the shell 1.

[0040] In this embodiment, two air inlets 101 are provided on one side of the housing 1 to increase the air intake and improve the cooling and heat dissipation effect inside the housing 1. At the same time, a dustproof component 3 can be detachably installed at each air inlet 101.

[0041] By detachably installing the dustproof component 3 at the air inlet 101, the fan component 2 can reduce the dust in the air from being sucked into the shell 1 when dissipating the heat to the board module 106 inside the shell 1, thereby reducing the accumulation of dust inside the shell 1. When a lot of dust is accumulated outside the dustproof component 3, the dustproof component 3 can be removed for cleaning without disassembling the shell 1. This has the advantages of simple structure and convenient operation.

[0042] In one embodiment, Figure 5 and Figure 6 As shown, the dustproof component 3 includes a dustproof net 301, and a plurality of filter holes are provided on the dustproof net 301.

[0043] Specifically, the dustproof net 301 in this embodiment has a shape that matches the air inlet 101, and the dustproof net 301 is formed by injection molding a plastic part and a nylon net. The plastic part has a certain structural strength and a certain deformation characteristic, and the nylon net is formed by a regular arrangement of many small and dense circular holes, and the commonly used density is 30 mesh and 50 mesh, and the commonly used thickness is 0.3 mm.

[0044] In this embodiment, a mounting groove is provided at the bottom of the shell 1, and the mounting groove is located at the air inlet 101. When installing the dustproof net 301, the dustproof net 301 is inserted into the mounting groove. After installation, the filter holes on the dustproof net 301 face the direction of the air inlet 101. After a certain period of use, the dustproof net 301 can be taken out of the mounting groove for cleaning and maintenance. There is no need to use any external disassembly tools. The dustproof net 301 can be easily and quickly disassembled by hand for cleaning operations.

[0045] By setting filter holes on the dustproof net 301, when the outside air is input into the shell 1, the filter holes can filter some dust and other particulate impurities in the air, reducing the accumulation of dust inside the shell 1. The dust accumulated on the dustproof net 301 can be cleaned by removing the dustproof net 301, which has the advantages of good dustproof effect and convenient operation.

[0046] In one embodiment, Figure 6 As shown, the housing 1 is provided with a limiting member 1041 at the air inlet 101 , and the dustproof assembly 3 further includes a buckle 302 arranged on the side of the dustproof net 301 , and the buckle 302 is detachably connected to the limiting member 1041 .

[0047] Specifically, in this embodiment, there are limiters 1041 on both sides of the installation slot at the air inlet 101, and buckles 302 are provided on both sides of the dustproof net 301. The buckles 302 are made of plastic and have certain elasticity and deformation ability. When the dustproof net 301 is installed, the buckles 302 on both sides of the dustproof net 301 are compressed under the extrusion of the installation slot. When the dustproof net 301 is completely installed in the installation slot, the buckles 302 at the position of the limiters 1041 extend outward and engage with the limiters 1041, thereby firmly installing the dustproof net 301 in the limiter slot. When taking out the dustproof net 301 again, pull the bottom of the dustproof net 301, the buckles 302 are squeezed and deformed at the limiters 1041, and are separated from the limiters 1041. At this time, the dustproof net 301 can be taken out of the installation slot for cleaning.

[0048] The dustproof net 301 can be firmly installed at the air outlet 102 through the detachable snap connection between the buckle 302 and the limiting member 1041 , and the dustproof net 301 can also be easily disassembled for cleaning.

[0049] In one embodiment, Figures 3 to 5 As shown, the shell 1 includes a first shell 103 and a second shell 104, the second shell 104 is connected to the first shell 103, the limiter 1041, the air inlet 101 and the air outlet 102 are arranged on the second shell 104, and the dustproof net 301 is detachably connected to the second shell 104.

[0050] Specifically, in this embodiment, the shell 1 is divided into two parts, a first shell 103 located at the top and a second shell 104 located at the bottom. The first shell 103 is made of aluminum alloy or magnesium alloy. The first shell 103 is provided with important components such as function buttons and trackballs for main human-computer interaction in the ultrasonic equipment, and is also designed with heat dissipation vents. The second shell 104 is made of aluminum alloy or magnesium alloy, and has excellent mechanical strength and natural heat dissipation performance. The second shell 104 is used to install the board module 106 and the fan assembly 2. The board module 106 will generate heat when working and is the main heat source in the equipment.

[0051] In this embodiment, the air inlet 101 and the air outlet 102 are symmetrically arranged on the side of the second shell 104, so that air can enter the second shell 104 through the air inlet 101 and output heat through the air outlet 102. The installation groove is arranged at the bottom of the second shell 104 at the position of the air inlet 101.

[0052] In one embodiment, Figure 6 As shown, the dustproof assembly 3 further includes a guide member 303 disposed on the side of the dustproof net 301, and the guide member 303 is slidably connected to the mounting groove.

[0053] Specifically, in this embodiment, guide members 303 are provided on both sides of the dustproof net 301. The guide members 303 are inclined along the installation direction, which can play a guiding role when installing the dustproof net 301, making it easy to install the dustproof net 301 into the installation groove.

[0054] By slidably connecting the guide member 303 with the mounting groove, the dustproof net 301 can be easily mounted on the second housing 104. Meanwhile, the mounting groove can also play a limiting role, so that the dustproof net 301 can be mounted more stably.

[0055] In one embodiment, Figure 6 As shown, a first limiting portion 1042 is provided at the bottom of the second shell 104 , and the dustproof assembly 3 further includes a second limiting portion 304 provided at the bottom of the dustproof net 301 , and the first limiting portion 1042 abuts against the second limiting portion 304 .

[0056] Specifically, in this embodiment, a first limiting portion 1042 is provided at the mounting groove at the bottom of the second shell 104, and the first limiting portion 1042 is a groove. A second limiting portion 304 is provided at the bottom of the dustproof net 301, and the second limiting portion 304 is a boss matching the first limiting portion 1042. When the dustproof net 301 is installed in the mounting groove, the second limiting portion 304 abuts against the first limiting portion 1042, which can limit the dustproof net 301 so that the installed dustproof net 301 and the second shell 104 are on the same plane.

[0057] By abutting the first limiting portion 1042 against the second limiting portion 304 , the dustproof net 301 can be limited so that it can be accurately installed at the air inlet 101 , thereby improving the filtering effect of impurities and dust in the air.

[0058] In one embodiment, Figure 4 and Figure 5 As shown, the housing 1 further includes a wind shield 105 fixedly connected to the second housing 104 , which is suitable for guiding the airflow at the air inlet 101 .

[0059] Specifically, in this embodiment, the wind shield 105 is in a “J” shape and is fixedly installed at the air inlet 101 on the inner side of the second shell 104 .

[0060] By setting the wind shield 105, a relatively closed shield ring can be formed at the air inlet 101, so that the outside air only flows along the air inlet direction, avoiding the gas from rushing around during the convection process of the air through the dustproof net 301 area, thereby maintaining a stable airflow direction.

[0061] In one embodiment, Figures 3 to 5 As shown, the housing 1 further includes a board module 106 fixedly mounted on the second housing 104 and located between the air inlet 101 and the air outlet 102 .

[0062] Specifically, the core board module 106 of the movement in this embodiment is also the main heat source of the equipment, and a heat dissipation structure is designed on it. In this embodiment, an efficient aluminum alloy radiator is combined with copper tubes and heat dissipation fins, which are soldered together in pairs to improve the efficiency of heat dissipation.

[0063] In one embodiment, Figure 4 and Figure 5 As shown, the fan assembly 2 includes a first fan 201 and a second fan 202. The first fan 201 is fixedly installed inside the second shell 104, located at the air inlet 101, and is suitable for blowing air toward the board module 106. The second fan 202 is fixedly installed inside the second shell 104, located at the air outlet 102, and is suitable for outputting the heat of the board module 106 to the air outlet 102.

[0064] Specifically, in this embodiment, a plurality of first fans 201 and second fans 202 are provided to improve the efficiency of heat dissipation. The first fan 201 is used to accelerate and increase the amount and speed of cold air entering the device to improve the heat dissipation effect, and the second fan 202 blows the heat concentrated on the heat dissipation fins to the external environment of the device on the one hand, and pumps the heat in the internal space of the device to the external environment on the other hand.

[0065] By providing two fans, the efficiency of air entering the housing 1 and being discharged to the outside can be improved, thereby improving the heat dissipation effect, so that the board module can work for a longer time to meet various required application occasions.

[0066] In one embodiment, Figure 7 As shown, a wrench position 1011 is provided at the bottom of the air inlet 101 .

[0067] Specifically, in this embodiment, the air inlet 101 is a multiple grille structure, and the wrench position 1011 is set in the middle position of the grille structure. The size of some grilles is set to be slightly smaller than the size of other grilles, so that a gap is formed at the air inlet 101, which can be used as a fulcrum for fingers to pull out when disassembling the dustproof component 3.

[0068] The wrench position 1011 is provided to facilitate the operator to remove the dust screen 301 from the second shell 104 .

[0069] In this embodiment, the first shell 103 is provided with a connecting part at the air outlet 102 to facilitate the connection of the display screen. The connecting part is two cylindrical sleeves, inside which the screen shaft can be installed. After installation, the screen can rotate around the connecting part to adjust the display screen to different viewing positions.

[0070] The operation process of this embodiment is as follows:

[0071] In the first step, the assembled board module 106 and the second fan 202 are assembled to the designated positions of the second housing 104, and then the two first fans 201 are installed in the slots on the second housing 104, and finally the wind shield 105 is fixed to the second housing 104 with screws, so that the second housing 104 is assembled;

[0072] In the second step, the pre-assembled first housing 103 and the second housing 104 assembled in the first step are fixed together with screws to form a device host;

[0073] Step 3: Installation method of dustproof component 3:

[0074] Install the dustproof component 3 at the bottom of the second shell 104, just above it (the vertical distance is about 10mm), align the guide member 303 of the dustproof component 3 with the corresponding installation groove of the second shell 104, and use the guiding effect of the guide member 303 (the installation groove is designed with guide grooves for sliding on all sides) to press vertically inward with your hand until the buckle 302 and the limiter 1041 on the second shell 104 are locked in place and are not easy to fall off. During installation, a slight sound will be emitted when the buckle 302 is deformed.

[0075] When the device is turned on and working normally, the cold air from the external environment passes through the filtering effect of the dustproof component 3 from the front side of the device, enters the interior of the host device from the air inlet 101 under the action of the first fan 201, passes through the heating device and the heat dissipation module on the board module 106, and then under the action of the second fan 202, on the one hand, the heat concentrated on the heat dissipation fins is blown to the external environment of the device, and on the other hand, the heat in the internal space of the device is pumped to the external environment. The hot air of the above two is blown to the external environment of the device through the air outlet 102, forming a complete exchange and filtration process of hot and cold air;

[0076] Step 4: After the host device has been working for a certain period of time, it needs to be cleaned and maintained regularly (such as 3 months or 6 months). Steps for disassembling the dustproof component 3:

[0077] Without using tools, use your finger to align the wrench position 1011 and pull it in the direction perpendicular to the outside of the device, so that the buckle 302 is deformed accordingly under the action of the external force and disengaged from the limiter 1041, so that the dustproof component 3 can be easily removed from the host device for cleaning. The cleaning method is not limited to washing with water and then drying or wiping with a rag.

[0078] After cleaning, the dustproof assembly 3 is installed back to the original position. The disassembly and assembly process of the dustproof assembly 3 is a mutually reverse process.

[0079] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
