The vacuum pump 21 has an intake end 211 and an air outlet end 212, and an intake end 211 extends in the chamber 12. The vacuum pump 21 is provided with a through hole 213 on the side of the air inlet 112 of the cover 111, and an intake switching valve 214 is disposed in the through hole 213 to be normally closed. The vacuum pump 21 is provided. Mainly, the air in the chamber 12 can be forcibly discharged to form a negative pressure, and a floating ball sensor 22 is provided at a position opposite to the lower end of the intake end 211 of the vacuum pump 21, and the floating ball sensor 22 can be subjected to water. The buoyancy force drives the intake end 211 of the vacuum pump 21 upwardly, and the outlet end 212 of the vacuum pump 21 is connected with a downwardly extending exhaust flow passage 23, and the exhaust flow passage 23 is arranged. The air end is further branched to form a first branch 231 and a second branch 232, wherein the first branch 231 has an exhaust port communicating with the outside. 4, and a third control valve 25 is provided in the first branch 231 for controlling whether the air is discharged outward through the exhaust port 24, and between the third control valve 25 and the exhaust port 24 Further, an air filter 26 is disposed, and the second branch 232 extends downward and is connected to the top of the liquid temporary storage tank 16, and a controllable air is disposed in the second branch 232. It is discharged into the fourth control valve 27 of the water liquid storage tank 16.
另於該水液暫存槽16中設有一水位感測器31,於本實施例中,該水位感測器31係由一高水位計311與一低水位計312組成,該各控制閥17、19、25、27係分別與該水位感測器31電性連結,且當該水位感測器31之高水位計311感應到該水液暫存槽16中累積到預定水量時,即關閉該第一控制閥17與第三控制閥25,並開啟該第二控制閥19與第四控制閥27,使位於該水液暫存槽16中之水液可藉由該第二支道232所排入之空氣加壓而確實由該排水口18向外排出。In addition, the water level sensor 31 is provided with a water level sensor 31. In the embodiment, the water level sensor 31 is composed of a high water level meter 311 and a low water level meter 312. The control valves 17 The 19, 25, and 27 series are electrically connected to the water level sensor 31, respectively, and when the high water level gauge 311 of the water level sensor 31 senses that the predetermined amount of water is accumulated in the liquid liquid storage tank 16, the system is turned off. The first control valve 17 and the third control valve 25, and the second control valve 19 and the fourth control valve 27 are opened, so that the water liquid located in the water liquid storage tank 16 can be passed through the second branch 232. The discharged air is pressurized and is actually discharged outward from the drain port 18.
而本發明之乾濕兩用吸塵裝置於實際使用時,如第2圖所示,當啟動該真空泵21運轉,該第一控制閥17與第三控制閥25係呈開啟狀態,而該第二控制閥19與第四控制閥27則處於關閉狀態,此時該真空泵21即可強制將該腔室12內部之空氣依序經該排氣流道23之第一支道231、空氣濾淨器26及該排氣口24而排出至該腔室12外部,使該腔室12內部得形成負壓,而可持續將外部之雜物或水液經該吸入管14與吸入口13吸入於該腔室12內部,此時經該吸入管14所吸入之灰塵即會被該濾網15統一集中,而當本發明之吸塵裝置吸入水液時,該等水液則會因本身重力而經該第一控制閥17流入該水液暫存槽16中儲存。In the actual use of the wet and dry dust collecting device of the present invention, as shown in FIG. 2, when the vacuum pump 21 is started to operate, the first control valve 17 and the third control valve 25 are in an open state, and the second The control valve 19 and the fourth control valve 27 are in a closed state. At this time, the vacuum pump 21 can forcibly pass the air inside the chamber 12 through the first branch 231 of the exhaust runner 23 and the air filter. 26 and the exhaust port 24 are discharged to the outside of the chamber 12 to form a negative pressure inside the chamber 12, and the external debris or water can be continuously sucked through the suction pipe 14 and the suction port 13 The inside of the chamber 12, at which time the dust sucked through the suction pipe 14 is uniformly concentrated by the filter 15, and when the dust suction device of the present invention sucks in the liquid liquid, the water liquid passes through the gravity itself. The first control valve 17 flows into the liquid liquid storage tank 16 for storage.
而當流入該水液暫存槽16中之水液到達該水位感測器31之高水位計311所設定之高水位值時,如第3圖所示,該水位感測器31即會令該第一控制閥17與該第三控制閥25呈關閉狀態,該第二控制閥19與第四控制閥27呈開啟狀態,此時,由該真空泵21所強制排出之空氣,即會改由該第二支道232而排入該水液暫存槽16中,並藉由該第二支道232所排入之空氣加壓作用,而可確實且快速地將位於該水液暫存槽16中之水液由該排水口18向外排出。When the water flowing into the water liquid storage tank 16 reaches the high water level value set by the high water level gauge 311 of the water level sensor 31, as shown in FIG. 3, the water level sensor 31 will cause The first control valve 17 and the third control valve 25 are in a closed state, and the second control valve 19 and the fourth control valve 27 are in an open state. At this time, the air forced to be discharged by the vacuum pump 21 is changed. The second branch 232 is discharged into the liquid liquid storage tank 16 and is pressurized by the air discharged from the second branch 232, so that the liquid liquid temporary storage tank can be reliably and quickly located. The water in the 16 is discharged outward from the drain port 18.
然於此必須特別提出說明的是,由於本發明之吸塵裝置在進行排水動作時,該第一控制閥17係處於關閉狀態,因此當吸水速度大於其排水速度時,位於該腔室12中之水液水位有可能將逐漸升高,此時如第4圖所示,當位於該腔室12中之水液水位逐漸升高而帶動該浮球感應器22對應封閉住該真空泵21之進氣端211,此時該浮球感應器22即會同步傳遞一切換訊號以令位於該通孔213中之進氣切換閥214改呈開啟狀態,使該真空泵21得改由該進氣口112吸入空氣,並由該第二支道232排入該水液暫存槽16中,而同樣可藉由排入該水液暫存槽16之空氣加壓作用,使位於該水液暫存槽16中之水液得確實且快速地由該排水口18向外排出之功效。反之,當位於該腔室12中之水液水位降低至該浮球感應器22不再封閉住該真空泵21之進氣端211時,該浮球感應器22即會再次傳遞切換訊號而令該進氣切換閥214回復呈關閉狀態,使該真空泵21得再回復成以其進氣端211吸入空氣,並經該第二支道232而排入於該水液暫存槽16中。However, it must be particularly noted that the first control valve 17 is in a closed state when the dust suction device of the present invention performs the draining operation, and therefore is located in the chamber 12 when the water absorption speed is greater than the drainage speed thereof. The water level of the water may gradually increase. At this time, as shown in FIG. 4, when the water level in the chamber 12 is gradually increased, the float sensor 22 is driven to close the intake of the vacuum pump 21. At the end 211, the float sensor 22 synchronously transmits a switching signal to change the intake switching valve 214 located in the through hole 213 to an open state, so that the vacuum pump 21 can be inhaled by the air inlet 112. The air is discharged into the liquid liquid storage tank 16 by the second branch 232, and can also be placed in the liquid liquid temporary storage tank 16 by the air pressurization discharged into the liquid liquid temporary storage tank 16. The effect of the water liquid in the water is discharged from the drain port 18 reliably and quickly. On the other hand, when the water level in the chamber 12 is lowered until the float sensor 22 no longer closes the intake end 211 of the vacuum pump 21, the float sensor 22 transmits the switching signal again. The intake switching valve 214 is returned to the closed state, so that the vacuum pump 21 is restored to take in air through its intake end 211 and is discharged into the liquid temporary storage tank 16 via the second branch 232.
而當位於該水液暫存槽16中之水位降低至該水位感測器31之低水位計312所設定之低水位值時,即會回復成第5圖所示,該水位感測器31即會令該各控制閥17、19、25、27回復成初啟動狀態,即該第二控制閥19與該第四控制閥27呈關閉狀態,而該第一控制閥17與第三控制閥25呈開啟狀態,使經該吸入口13所吸入水液得再次經該第一控制閥17而暫時儲存於該水液暫存槽16中。When the water level in the water liquid storage tank 16 is lowered to the low water level value set by the low water level gauge 312 of the water level sensor 31, it will return to the water level sensor 31 as shown in FIG. That is, the control valves 17, 19, 25, 27 are returned to the initial starting state, that is, the second control valve 19 and the fourth control valve 27 are in a closed state, and the first control valve 17 and the third control valve are closed. 25 is in an open state, so that the water sucked through the suction port 13 is again temporarily stored in the liquid liquid storage tank 16 via the first control valve 17.
經由上述說明後可知,本發明之乾濕兩用吸塵裝置僅需藉由真空泵21與該等控制閥17、19、25、27之切換即可達到吸塵及排水之作用,而不需額外增設排水泵結構,且本發明於實際進行排水動作時,更可藉由該第二支道232所排入之空氣加壓,使位於該水液暫存槽16中之水液可確實、快速地經由該排水口18向外排出。It can be seen from the above description that the wet and dry dust collecting device of the present invention only needs to be switched by the vacuum pump 21 and the control valves 17, 19, 25, 27 to achieve the functions of vacuuming and draining, without additional drainage. The pump structure, and the present invention can be pressurized by the air discharged from the second branch 232 when the drainage operation is actually performed, so that the liquid liquid located in the liquid temporary storage tank 16 can be reliably and quickly passed. The drain port 18 is discharged outward.
再者,本發明之水位感測器31係藉由其高、低水位計311、312而可感測位於該水液暫存槽16中之水量,並藉此可達到自動排水之功效。Furthermore, the water level sensor 31 of the present invention can sense the amount of water in the liquid liquid storage tank 16 by its high and low water level gauges 311, 312, thereby achieving the effect of automatic drainage.
惟,以上所述實施例之揭示係用以說明本發明,並非用以限制本發明,故舉凡數值之變更或等效元件之置換仍應隸屬本創作之範疇。The disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the present invention.
綜上所述,係可使熟知本項技藝者明瞭本發明的確可達成前述目的,實已符合專利法之規定,故本案發明人爰依法提出申請。In summary, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objectives and is in accordance with the provisions of the Patent Law.
