DETAILED DESCRIPTION

[0018] The present invention is further described below with reference to the accompanying drawings and specific embodiments: Example: Reference Figure 1 - Figure 6 The present invention discloses an industrial vacuum cleaner with a sterilization and disinfection function, comprising a housing 1, an outer wall of the housing 1 is provided with an exhaust groove 4, and a fan 5 for generating negative pressure is fixedly connected in the exhaust groove 4; The cyclone assembly 2 is mainly composed of a cyclone bin 201 and a dust collecting box 202. An air inlet pipe 6 is fixedly connected to the side of the shell 1 away from the fan 5. The air inlet pipe 6 extends into the shell 1 and is fixedly connected to the cyclone bin 201. The output end of the air inlet pipe 6 is connected to the top of the outer wall of the cyclone bin 201 in a tangential manner. The top of the cyclone bin 201 is connected to the fan 5 through an exhaust pipe 7. One end of the exhaust pipe 7 is located at the top of the cyclone bin 201 and extends downward to below the output end of the air inlet pipe 6. The bottom of the cyclone bin 201 protrudes downward to form a funnel portion 8, and the bottom of the funnel portion 8 is connected to the dust collecting box 202 through a connecting pipe 9; The sterilization component 3 is composed of a water storage tank 31, an evaporation chamber 32 and a high-temperature electric heater 33. The evaporation chamber 32 is provided above the cyclone chamber 201 in the housing 1. The water storage tank 31 is provided on one side of the evaporation chamber 32 close to the fan 5 in the housing 1. The bottom of the water storage tank 31 is connected to the evaporation chamber 32 through a water supply pipe 10. An exhaust pipe 11 is fixedly connected to the top of the evaporation chamber 32, and the end of the exhaust pipe 11 away from the evaporation chamber 32 is connected to the air inlet pipe 6. The outer wall of the end of the exhaust pipe 11 close to the air inlet pipe 6 is concave to form a throat 12. The exhaust pipe 11 is located on the side of the throat 12 away from the air inlet pipe 6 and is fixedly connected to a high-temperature electric heater 33 for secondary heating of steam.

[0019] In this embodiment, observe Figure 1 and Figure 3It can be found that an exhaust groove 4 is opened on the outer wall of the shell 1, and a fan 5 is installed in the exhaust groove 4, then an air inlet pipe 6 is connected to the side of the shell 1 away from the exhaust groove 4, and the air inlet pipe 6 is inserted into the shell 1, and then a cyclone bin 201 is fixedly connected to the output end of the air inlet pipe 6, so that the output end of the air inlet pipe 6 is connected to the top of the outer wall of the cyclone bin 201 in a tangential manner, and finally the top of the cyclone bin 201 is connected to the fan 5 through the exhaust pipe 7, and the end of the exhaust pipe 7 is extended into the cyclone bin 201, and the input end of the exhaust pipe 7 is as shown in FIG. Figure 4 As shown, the exhaust pipe 7 extends into the cyclone bin 201, and the bottom of the input end of the exhaust pipe 7 is located below the output end of the inlet pipe 6. At this time, the fan 5 is started to generate a negative pressure in the exhaust pipe 7, thereby generating a negative pressure in the cyclone bin 201, so that air is sucked into the cyclone bin 201 through the inlet pipe 6, thereby achieving the effect of suction. Therefore, a vacuum cleaner hose and a suction head are installed at the input end of the inlet pipe 6 to achieve the effect of dust suction.

[0020] After the dust is sucked into the air inlet 6, the dust flowing with the high-speed air will enter the cyclone chamber 201 in a tangential manner to the inner wall of the cyclone chamber 201. Then, the high-speed airflow will rotate in the cyclone chamber 201, so that the dust and garbage with larger specific gravity will be centrifugally thrown out, and the dust and garbage will be deposited downward along the inner wall of the cyclone chamber 201. Then, the dust and garbage will be observed. Figure 2 It can be found that a funnel portion 8 is provided at the bottom of the cyclone bin 201, and the bottom of the funnel portion 8 is connected to a dust box 202 through a connecting pipe 9, so that the dust and garbage can be in the cone part, the airflow rotation radius is reduced, and the tangential speed is increased, which is used to improve the separation effect of dust and garbage. Finally, the dust and garbage particles move downward along the spiral line, and the airflow rotates upward near the bottom of the cone, while the particles with specific gravity enter the dust box 202 along the connecting pipe 9 for collection, thereby achieving the effect of separating and collecting the dust and garbage particles from the air.

[0021] However, since dust and garbage can carry bacteria, conventional ultraviolet light sterilization will be blocked by the outer layer of dust, resulting in poor intensity of ultraviolet radiation on the garbage in the center, affecting the sterilization effect.

[0022] So observe Figure 3It can also be found that an evaporation chamber 32 is provided in the housing 1, and a water storage tank 31 is provided on one side of the evaporation chamber 32, so that the evaporation chamber 32 and the water storage tank 31 are connected through the water supply pipe 10, and a water pump 23 is connected to the water supply pipe 10, so that the water pump 23 can pump water into the evaporation chamber 32 through the water storage tank 31, and use the evaporator in the evaporation chamber 32 to turn the water into high-temperature steam, and then discharge the steam through the exhaust pipe 11, and finally merge into the air intake pipe 6, so that the steam will mix with the dust particles after entering the air intake pipe 6, and use the high-temperature steam to coagulate and denature the bacterial cell protein to achieve the purpose of sterilization, and achieve the effect of sterilization. At the same time, the way in which steam and dust are rotated and mixed in the cyclone chamber 201 can make the dust particles and garbage fully contact with the high-temperature steam, which can effectively ensure the effect of sterilization.

[0023] When the fan 5 is exhausting air, the air inlet pipe 6 will continue to maintain a negative pressure state, so the exhaust pipe 11 connected to the air inlet pipe 6 will also generate a negative pressure, which will actively draw the steam into the air inlet pipe 6, thereby improving the mixing efficiency of the steam. Figure 2 It can also be found that a throat 12 with a smaller diameter is provided on the outer wall of the exhaust pipe 11 close to the air inlet pipe 6, which can speed up the water vapor when it is pulled through the throat 12, and further increase the flow rate of the high-temperature steam, so that the high-temperature steam and garbage dust are mixed more evenly, thereby further increasing the coverage rate of the high-temperature steam and making the sterilization effect stronger.

[0024] Since high-temperature steam will release heat when it flows, the overall temperature of the steam will drop again when it mixes with normal-temperature air, resulting in the temperature failing to meet the sterilization requirements. Therefore, a high-temperature electric heater 33 is connected to the side of the exhaust pipe 11 away from the throat 12, so that the high-temperature water vapor passing through the high-temperature electric heater 33 is heated to superheated steam, which is used to increase the temperature of the steam. Subsequently, the superheated steam will cool down and release heat when mixed with air. When the superheated steam is cooled to saturated water vapor, as the temperature continues to drop, the latent heat in the saturated water vapor dissipates, and the dust particles are heated up for a second time, which can be used to ensure the sterilization effect. At the same time, the cooling of the saturated water vapor will precipitate condensed water, causing the dust particles to mix with the condensed water, further increasing the specific gravity of the dust particles, thereby making the separation of dust and air in the cyclone bin 201 better, further improving the dust removal effect.

[0025] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 5As shown, the dust box 202 includes a collection bucket 2021, a waterproof filter 2022 and a connection end cover 2023, the connection end cover 2023 is fixed to the outer wall of the connection pipe 9, the bottom of the connection end cover 2023 is located on the outside of the connection pipe 9 and is clamped with the waterproof filter 2022, and the bottom outer edge of the connection end cover 2023 is threadedly connected with the collection bucket 2021; The bottom of the collection barrel 2021 is connected to a drain pipe 13, one end of the drain pipe 13 away from the collection barrel 2021 is connected to the water supply pipe 10, and an electromagnetic three-way valve is provided at the connection point; The collecting barrel 2021 and the evaporation chamber 32 are both fixedly connected with a water level alarm 14. The water level alarm 14 in the collecting barrel 2021 is arranged at the bottom of the inner wall, and the water level alarm 14 in the evaporation chamber 32 is connected to the side wall and is located above the evaporator.

[0026] In this embodiment, since the high-temperature steam will cool down and produce condensed water when mixed with air, the dust and garbage entering the dust box 202 will contain a large amount of water. Figure 5 It can be found that the dust collecting box 202 is composed of a collecting bucket 2021, a waterproof filter screen 2022 and a connecting end cover 2023, and the connecting end cover 2023 is fixedly connected to the connecting pipe 9, and the bottom of the connecting end cover 2023 is located on the outside of the connecting pipe 9 and is clamped with a waterproof filter screen 2022. Finally, the collecting bucket 2021 is threadedly connected to the bottom outer edge of the connecting end cover 2023, so that the dust and garbage entering the collecting bucket 2021 can first contact with the waterproof filter screen 2022, and then the dust and garbage are accumulated in large quantities at the bottom of the waterproof filter screen 2022. At this time, the condensed water enriched on the surface of the dust and garbage will leak to the bottom of the collecting bucket 2021 along the gap of the waterproof filter screen 2022, and the condensed water of the water vapor will be collected to reduce water loss.

[0027] And in Figure 5 It can also be found that a water level alarm 14 is connected to the bottom of the inner wall of the collection barrel 2021, and a drain pipe 13 is connected to the outer wall of the collection barrel 2021, and the end of the drain pipe 13 away from the collection barrel 2021 is connected to the water supply pipe 10, and an electromagnetic three-way valve is provided at the connection point. Figure 3It can be found that a water level alarm 14 is also connected above the evaporator in the evaporation chamber 32. At this time, when the water level in the evaporation chamber 32 is lower than the water level alarm 14, a signal will be sent to enable the water pump 23 to operate to pump water. When the water level alarm 14 in the collection barrel 2021 detects that there is enough water, the electromagnetic three-way valve will open the drain pipe 13, so that the water pump 23 can pump the water in the collection barrel 2021 through the drain pipe 13 to achieve water recycling; and when the water level alarm 14 in the collection barrel 2021 detects that there is insufficient water, the electromagnetic three-way valve will be connected to the water tank 31, and the water in the water tank 31 will be used for water supply to ensure that the water level in the evaporation chamber 32 will not be lower than the evaporator, causing the evaporator to burn out and be damaged.

[0028] observe Figure 3 It can be found that a water inlet 24 is connected to one side of the water tank 31 , which can supply water to the water tank 31 to ensure that there is enough water in the water tank 31 to ensure the generation of steam in the evaporation chamber 32 .

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, the inner bottom wall of the evaporation chamber 32 is located at the output end of the water supply pipe 10 and is fixedly connected to a one-way valve 15 , and the inner top wall of the evaporation chamber 32 is located at the input end of the exhaust pipe 11 and is fixedly connected to a pressure valve 16 .

[0030] In this embodiment, since the evaporation chamber 32 is connected to the water storage tank 31 through the water supply pipe 10, and water has excellent thermal conductivity, the evaporator will heat the water in the evaporation chamber 32 together with the water in the water storage tank 31, affecting the heating speed and thus affecting the steam generation efficiency. Figure 3 It can be found that a one-way valve 15 is fixedly connected to the inner bottom wall of the evaporation chamber 32 at the output end of the water supply pipe 10 to prevent hot water from mixing with cold water, thereby reducing heat loss and effectively ensuring the efficiency of steam generation in the evaporation chamber 32.

[0031] By fixing the pressure valve 16 at the input end of the exhaust pipe 11 on the inner top wall of the evaporation chamber 32, water vapor will not be directly sucked away by the intake pipe 6 when it is generated, but will be collected at the top of the evaporation chamber 32, which can be used to increase the water vapor content, so that the water vapor forms saturated water vapor, and at the same time increase the pressure of the saturated water vapor, so that the saturated water vapor has a higher initial velocity when it pushes open the pressure valve 16 and is discharged, which is used to improve the mixing efficiency of steam and normal temperature air. At the same time, the saturated water vapor contains a large amount of latent heat, which can further improve the heating effect on the normal temperature air, thereby improving the sterilization effect.

[0032] When the latent heat of saturated water vapor is released, more condensed water will be produced, thereby increasing the specific gravity of dust particles and further enhancing the dust removal effect.

[0033] In a further preferred embodiment of the present invention, Figure 3 and Figure 6 As shown, one end of the exhaust pipe 7 away from the cyclone chamber 201 extends obliquely upward to form an inclined section 17, and a plurality of heat-conducting fins 18 are fixedly connected in the inclined section 17. One side of the heat-conducting fins 18 extends out of the exhaust pipe 7 and is inserted into the water supply pipe 10. An insulation sleeve 19 for wrapping the heat-conducting fins 18 is provided on the outer side of the water supply pipe 10 and the inclined section 17.

[0034] In this embodiment, since the high-temperature air and the normal-temperature air will still have a high heat content after being mixed, direct discharge of the mixed air will result in heat loss and waste, affecting energy utilization efficiency.

[0035] So observe Figure 3 It can be found that a heat-conducting fin 18 is inserted into the exhaust pipe 7, and the heat-conducting fin 18 extends out of the exhaust pipe 7 and is inserted into the water supply pipe 10. At this time, when the mixed air passes through the heat-conducting fin 18, the heat will be introduced into the water supply pipe 10 by the heat-conducting fin 18, heating the cold water in the water tank 31, so that the water in the water tank 31 has a higher temperature when it flows into the evaporation chamber 32, which can further improve the evaporation efficiency.

[0036] At the same time, the moisture in the mixed air that is further cooled will further condense, causing a large amount of condensed water to be generated in the exhaust pipe 7. Figure 3 and Figure 6 It can be found that the end of the exhaust pipe 7 away from the cyclone chamber 201 is extended obliquely upward to form an inclined section 17, and the heat-conducting fins 18 are installed in the inclined section 17. At this time, the dripping condensed water will directly flow back along the inclination of the inclined section 17, and then drip into the dust collecting box 202 through the input end of the exhaust pipe 7 for collection. While recovering heat energy, water resources are further recovered, which can effectively improve the practicality of the industrial vacuum cleaner.

[0037] Since the heat conducting fins 18 connect the water supply pipe 10 and the air extraction pipe 7, the heat conducting fins 18 located between the water supply pipe 10 and the air extraction pipe 7 will introduce heat into the air, resulting in heat waste. Figure 6 It can be found that an insulation sleeve 19 is provided on the outer side of the water supply pipe 10 and the inclined section 17. The insulation sleeve 19 is used to wrap the portion of the heat-conducting fins 18 exposed to the air, which can effectively reduce heat loss and further improve energy utilization efficiency.

[0038] In a further preferred embodiment of the present invention, Figure 1 and Figure 2As shown, a square groove 20 is formed on the outer wall of the shell 1 at one side of the dust box 202 , a supporting cylinder 21 for supporting the dust box 202 is fixedly connected to the bottom of the square groove 20 , and a baffle 22 is hinged at the opening of the square groove 20 .

[0039] In this embodiment, since the dust box 202 is used to collect garbage, when the industrial vacuum cleaner is operated for a long time, a lot of garbage will accumulate in the dust box 202, affecting the subsequent use. Figure 1 and Figure 2 It can be found that a square groove 20 is opened on one side of the outer wall of the shell 1 close to the dust box 202, and a supporting cylinder 21 for supporting the dust box 202 is connected to the square groove 20. Finally, a baffle 22 is hinged at the opening of the square groove 20, so that when it is necessary to clean the garbage, the baffle can be opened and the dust box 202 can be removed to clean the garbage in the dust box 202, making the subsequent cleaning of the industrial vacuum cleaner simpler and more convenient.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
