[0008] A vacuum assembly includes a host computer installed in the host computer room and an exhaust pipe. A fan is installed inside the host computer's casing. The host computer's casing has a heat dissipation gas inlet and a heat dissipation gas outlet. The fan is used to draw heat dissipation gas from the host computer room into the host computer through the heat dissipation gas inlet and discharge it through the heat dissipation gas outlet. The exhaust pipe is connected to the exhaust window on the chassis and the heat dissipation gas outlet on the casing.

[0009] Furthermore, the vacuum assembly also includes:

[0011] An inlet filter assembly is detachably connected to the air intake end of the main unit.

[0012] A noise reduction assembly is detachably connected to the air outlet of the main unit.

[0013] Furthermore, the inlet filter assembly includes an inlet pipe installed on the chassis and extending into the main unit room, and an inlet filter device disposed outside the chassis and connected to the inlet pipe.

[0019] The gas filtration assembly is used to filter the gas entering the electrical room through the air inlet window;

[0020] The interactive component is used to receive control commands, control the operation of the vacuum pump unit, and provide feedback on the operating status.

[0021] Furthermore, the gas filter assembly includes a grid door that is flip-mounted at the air intake window, and filter cotton sandwiched between the air intake window and the grid door.

[0022] Furthermore, the interactive component includes a touchscreen housing and a cover plate, the cover plate being flip-mounted at the opening of the touchscreen housing;

[0023] It also includes a touchscreen, indicator lights, and an emergency stop switch installed in the touchscreen box, so that staff can promptly detect abnormalities and stop the machine quickly.

[0028] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0029] This invention relates to a vacuum pump unit that integrates most of its structure within a single enclosure by dividing the chassis into a main unit compartment and an electrical compartment. This high degree of integration reduces the overall size of the vacuum pump unit, saving space and making it suitable for a wider range of working environments. Furthermore, during operation, external gas enters the electrical compartment through the inlet window, cools the components there, and then enters the main unit compartment through the vent window. From there, it enters the main unit casing to cool the main unit before being directly discharged from the chassis. This creates a fixed flow path for the external gas within the chassis, effectively cooling the main unit and other components. This eliminates the need for complex heat dissipation structures, simplifying the cooling process and reducing operating costs.

[0030] Furthermore, the main unit is fixed to the chassis base plate with bolts, and the air inlet end of the main unit is detachable from the inlet pipe, and the air outlet end is detachable from the outlet pipe. When the main unit malfunctions, it is convenient to disassemble for repair or replacement, which improves its practicality.

[0031] Furthermore, the vacuum pump unit of this utility model has multiple threaded holes on the partition and the bottom plate of the main unit chamber, which can install frequency converters and main units of different sizes. Therefore, it is not necessary to set the size of the chassis according to the size of the main unit, so that the size of various chassis is uniform, reducing the manufacturing error rate. The vacuum pump unit has a consistent appearance and specifications, which facilitates the production and processing of the chassis. Attached Figure Description

Detailed Implementation

[0043] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0044] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model. Example:

[0045] refer to Figures 1 to 10 This embodiment provides a vacuum pump unit, including a casing 1 and a vacuum pumping assembly 2.

[0046] The inner cavity of the chassis 1 is divided into a main unit compartment 101 and an electrical compartment 102 by a partition 3. An exhaust window for gas discharge is provided on the chassis 1 on one side of the main unit compartment 101. For example, the exhaust window is provided on the bottom plate of the chassis 1. An air inlet window 603 for gas to enter the electrical compartment 102 is provided on the chassis 1 on the other side of the electrical compartment 102. A vent 301 is provided on the partition 3. The vent 301 is used to allow the gas in the electrical compartment 102 to cool the components in the electrical compartment 102 before entering the main unit compartment 101.

[0047] The vacuum assembly 2 includes a main unit 201 and an exhaust pipe 202 installed in the main unit chamber 101. A fan (not shown) is installed inside the casing of the main unit 201. The specific structure of the fan installed inside the casing of the main unit 201 can be found in the utility model patent with announcement number CN210218158U: an air suspension centrifugal vacuum pump. Therefore, it will not be described in detail in this utility model embodiment. The casing of the main unit 201 is provided with a heat dissipation gas inlet and a heat dissipation gas outlet. The fan is used to draw the heat dissipation gas in the main unit chamber 101 into the main unit 201 from the heat dissipation gas inlet and discharge it from the heat dissipation gas outlet. The exhaust pipe 202 is connected to the exhaust window on the chassis 1 and the heat dissipation gas outlet on the casing.

[0048] This embodiment of a vacuum pump unit, by dividing the chassis 1 into a main unit chamber 101 and an electrical chamber 102, integrates most of the vacuum pump unit's structure within the chassis 1, achieving a high degree of integration, reducing the overall size of the vacuum pump unit, saving space, and making it suitable for more working environments. Furthermore, during operation, external gas enters the electrical chamber 102 through the inlet window 603, cools the components within the electrical chamber 102, then enters the main unit chamber 101 through the vent window 301, further cooling the main unit 201, and finally exits directly from the chassis 1. This creates a fixed flow path for the external gas within the chassis 1, cooling the main unit 201 and other components. This achieves heat dissipation without the need for complex heat dissipation structures, simplifying the heat dissipation method and reducing operating costs.

[0049] In a preferred embodiment, the air inlet window 603 of the electrical compartment 102 is located near the bottom of the chassis 1, and the ventilation window 301 of the partition 3 is located near the top of the chassis 1. External air can flow a relatively long distance in the electrical compartment 102 before entering the main unit compartment 101, which can fully cool the components in the electrical compartment 102.

[0050] In a preferred embodiment, the vacuum assembly 2 also includes a heat dissipation filter 203, an inlet filter assembly, and a noise reduction assembly. Gas enters the main unit 201 through the heat dissipation filter 203 to dissipate heat from the main unit 201, which can better protect the main unit 201, prevent overheating, and increase the service life of the equipment.

[0051] The heat dissipation filtration device 203 is connected to the heat dissipation gas inlet on the casing of the host 201, and is used to filter the heat dissipation gas entering the host 201. It performs secondary filtration on the heat dissipation gas entering the host 201 to further improve the cleanliness of the gas and prevent impurities in the gas from affecting the normal operation of the host 201, thus improving reliability.

[0052] The inlet filter assembly is detachably connected to the air inlet of the main unit 201, which is a port for vacuuming. The inlet filter assembly includes an inlet pipe 204 installed on the chassis 1 and extending into the main unit chamber 101, and an inlet filter device 205 located outside the chassis 1 and connected to the inlet pipe 204. The inlet filter device 205 can filter impurities. The end of the inlet pipe 204 away from the inlet filter device 205 is detachably connected to the air inlet of the main unit 201 via a connector 206. The user connection interface of the inlet filter device 205 provides two connection methods: flange connection and PVC pipe direct insertion.

[0053] The silencing component is detachably connected to the air outlet of the main unit 201. The silencing component includes an outlet pipe 207 installed on the chassis 1 and extending into the main unit room 101, and an outlet silencer 208 located outside the chassis 1 and connected to the outlet pipe 207. The end of the outlet pipe 207 away from the outlet silencer 208 is detachably connected to the air outlet of the main unit 201 via a connector 206. Preferably, the connector 206 is a pipe connector or a fire clamp, which facilitates the disassembly of the main unit 201 from the inlet pipe 204 and the outlet pipe 207, making it easier to maintain and replace the main unit 201. The inlet filter device 205 and the outlet silencer 208 are both located outside the chassis 1, making the chassis 1 more compact and the inlet filter device 205 easier to clean.

[0054] The main unit 201 of existing vacuum pump units is not easy to disassemble, making repair or replacement inconvenient when damaged, resulting in low practicality. Furthermore, due to the different specifications and sizes of the main unit 201, existing vacuum pump units require the chassis 1 size to be set according to the size of the main unit 201, leading to inconsistent chassis 1 sizes and inconsistent vacuum pump unit external dimensions, which is inconvenient for chassis 1 production and processing. As a preferred embodiment, in this example, the bottom plate of the chassis 1 on one side of the main unit chamber 101 is provided with several threaded holes (not shown) suitable for mounting main units 201 of different sizes. The main unit 201 is mounted on the bottom plate with bolts, allowing the vacuum pump unit to assemble main units 201 of different sizes without changing the overall appearance of the unit, thus increasing flexibility. In addition, the threaded holes on the bottom plate of the chassis 1 do not penetrate the chassis 1, making the chassis 1 cavity a closed structure, so that gas can be filtered through the gas filter assembly 6 at the air inlet window 603 before entering the main unit chamber 101, improving the cleanliness of the heat dissipation gas.

[0055] As a preferred embodiment, the inner wall of the chassis 1 on one side of the host room 101 is fitted with sound insulation cotton 5 by pressure strip 4, and the side of the partition 3 facing the host room 101 is fitted with sound insulation cotton 5 by pressure strip 4, thereby improving the sound insulation effect of the host 201 during operation and reducing the impact of noise on the surrounding environment.

[0056] In a preferred embodiment, a gas filter assembly 6 and an interaction assembly 7 are provided on the chassis 1 on one side of the electrical room 102.

[0057] The gas filter assembly 6 is used to filter the gas entering the electrical room 102 through the air inlet window 603. The gas filter assembly 6 includes a grid door 601 that is rotatably installed at the air inlet window 603, and a filter cotton 602 sandwiched between the air inlet window 603 and the grid door 601, which improves the cleanliness of the heat dissipation gas and facilitates timely replacement of the filter cotton 602.

[0058] The interactive component 7 is used to receive control commands, control the operation of the vacuum pump unit, and provide feedback on the operating status. The interactive component 7 includes a touch screen box 701 and a cover plate 702. The cover plate 702 is rotatably installed at the opening of the touch screen box 701. The interactive component 7 also includes a touch screen, indicator lights, and an emergency stop switch installed inside the touch screen box 701, so that staff can promptly detect abnormalities and quickly stop the machine, thereby improving work safety.

[0059] In a preferred embodiment, a circuit breaker 8 and a frequency converter 9 are installed in the electrical room 102. The circuit breaker 8 is installed on the inner wall of the chassis 1 on one side of the electrical room 102 through a circuit breaker box. The opening of the circuit breaker box is located on the side of the chassis 1, and a sealing door that can be opened and closed is provided at the opening. The circuit breaker 8 can be switched on and off by opening the sealing door, which is convenient to use.

[0060] The frequency converter 9 is bolted to the side of the partition 3 facing the electrical room 102. The partition 3 is provided with several threaded holes suitable for installing frequency converters 9 of different sizes, so that the vacuum pump unit can be equipped with frequency converters 9 of different sizes without changing the overall appearance of the unit.

[0061] After startup, the vacuum pump unit in this embodiment implements two gas flow paths. One is for evacuating external equipment: when the main unit 201 operates, negative pressure is drawn at the inlet end of the main unit 201. The gas from the external equipment is filtered through the inlet filter device 205 and then drawn into the main unit 201, finally being discharged from the outlet silencer 208. Figure 9 .

[0062] Secondly, the vacuum pump unit itself is cooled: external gas is filtered by the gas filter assembly 6 and enters the electrical room 102 through the air inlet window 603 on the chassis 1, cooling the frequency converter 9 and other components inside the electrical room 102. Then, the gas enters the main unit room 101 through the vent 301 on the partition 3. The fan inside the main unit housing operates, drawing the gas filtered by the heat dissipation filter device 203 into the main unit 201, cooling the main unit 201. Finally, the gas is discharged from the main unit housing and chassis 1 through the exhaust pipe 202. Figure 10 .

[0063] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
