And a spring 124 that generates an elastic force.

  When the suction hose 120 is coupled to the foreign matter discharge port 134, the brush switch S20 enables the brush 140 to operate when the suction switch 120 is turned on, and when the suction hose 120 is released from the foreign matter discharge port 134, When the brush switch S20 is turned off, the operation of the brush 140 is stopped. Such a brush switch S20 is a push button switch.

  More specifically, when the suction hose 120 is inserted and coupled to the foreign matter discharge port 134, the switch protrusion 122 of the suction hose 120 presses the brush switch S20, and the brush switch S20 compresses the spring 124 while moving in the moving space 126. The-terminal 125 and the + terminal 127 which are spaced apart from each other inside the moving space 126 are electrically connected, and the brush motor 142 can be driven.

  When the coupling of the suction hose 120 from the foreign matter discharge port 134 is released, the push state by the switch protrusion 122 is released. At this time, the brush switch S30 returns to the original position by the elastic force of the spring 124 that has been compressed. Therefore, the spring 124 compressed by the switch protrusion 122 is released and elastic force is generated.

  Therefore, the electrical connection between the negative terminal 125 and the positive terminal 127 in the moving space 126 is released by the return of the brush switch S20, and thereby the power supply of the brush is cut off. Then, the power supply is quickly shut off by releasing the connection between the negative terminal 125 and the positive terminal 127.

  On the other hand, the brush switch S20 can be a detection type switch that detects whether or not the suction hose 120 is coupled. Such a detection type switch is switched by detecting light or detecting a physical operation or touching it.

  Therefore, a contact sensor, a light detection sensor, a motion detection sensor, or the like is used for the brush switch S20.

  The ultraviolet lamp 150 is coupled to a lamp housing 152 coupled to the front of the suction unit 130 and is operated by the main switch S10. The lamp housing 152 is integrally coupled to the front of the suction portion 130.

  FIG. 7 is a sectional view showing another embodiment of the vacuum cleaner according to the present invention.

  As shown in FIG. 7 or FIG. 9, in this embodiment, the lamp housing 152 is integrally joined, but as a different embodiment, it is formed as a separate type.

  Such a separate lamp housing 152 is slidingly coupled to a home 137 formed on the surface of the suction portion 130 with a housing protrusion 154 formed thereon. In this case, a power terminal 136 and a lamp switch S30 are included to connect a power source.

  The power terminal 136 is in contact with a home terminal 137 connected to a lamp switch S30 that controls the power of the main switch S10. The power supply terminal 136 connected in this way is connected to a home terminal 137 provided at the home, whereby power is supplied to the ultraviolet lamp 150.

  Such a lamp switch is connected between the main switch S10 and the home terminal 137 to control the power supply.

  FIG. 8 is a circuit diagram for explaining another embodiment of the ultraviolet lamp of the vacuum cleaner according to the present invention.

  As shown in FIG. 8, in the present embodiment, the ultraviolet lamp 150 is operated by the main switch, but unlike this, it can be operated by the brush switch S20. By operating with the brush switch S20, when the suction hose 120 coupled to the foreign matter discharge port 134 of the suction unit 130 is released when used in a space or a place where the suction unit 130 cannot enter, the brush 140 also operates. The operation of the ultraviolet lamp 150 is also stopped. Therefore, when the operation of the ultraviolet lamp 150 is not necessary, the ultraviolet lamp 150 can be turned off, and power consumption can be reduced.

  FIG. 9 is a circuit diagram for explaining still another embodiment of the ultraviolet lamp of the vacuum cleaner according to the present invention, and FIG. 10 is a sectional view showing the embodiment of FIG.

  As shown in FIG. 9, in the present embodiment, the ultraviolet lamp 150 is directly supplied with power by the main switch S10, but this is coupled to the main switch S10 and the ultraviolet lamp 150 as another embodiment. A lamp switch S30 for controlling the ultraviolet lamp 150.

  At this time, the lamp switch S30 is formed in one of a built-in type incorporated in the main body 110 or an exterior type not coupled to the main body 110.

  As shown in FIG. 10, the lamp switch S30 is a switch that is turned “on” when contacting the ground. A push button switch is used as such a switch.

  In the lamp switch S30, at the moment when the wheel 117 and the ground contact, the wheel 117 presses the lamp switch S30, the lamp switch S30, the -lamp terminal 157 and the + lamp terminal 156 are contacted, and the power is applied. As a result, the ultraviolet lamp 150 is operated, and when the present embodiment is separated from the ground again, the lamp switch S30 pressed by the wheel 117 is released. In this case, the lamp switch S30 is returned to the original state by the spring 157. Return to state.

  As described above, when the lamp switch S30 is returned to the original state, the −lamp terminal 157 and the + lamp terminal 156 are disconnected, and the operation of the ultraviolet lamp 150 is stopped.

  As described above, the reason why the wheel 117 is turned on when it is brought into contact with the ground and is turned off when the wheel 117 is separated from the ground is that the ultraviolet rays from the ultraviolet lamp 150 are harmful to human skin and eyes. The lamp switch S30 is turned “ON” when the user is away from the ground, and the lamp switch S30 is turned “OFF” so as not to get into the user's skin or eyes when the user is away from the ground.

  On the other hand, the lamp switch S30 can be a contact sensor that detects light, a light detection sensor, a one-touch sensor, or the like.

  Therefore, the ultraviolet lamp 150 can be automated depending on whether or not the wheel 117 and the ground can be contacted using the lamp switch S30 using a contact sensor, a light detection sensor, and a one-touch sensor. More specifically, since the ultraviolet rays from the ultraviolet lamp 150 are harmful to the user's skin and eyes, the lamp switch S30 is turned on when it touches the ground, and is turned off when it does not touch the ground. .

  In addition, switching is performed at the moment when the wheel 117 comes into contact with the ground, and the switched one at the moment when the wheel 117 is separated from the ground is turned off, so that switching can be easily performed.

  Hereinafter, with reference to the attached drawings, the operational relationship of the embodiment according to the present invention will be described.

  As shown in FIGS. 2 to 6, in the present embodiment, when the user turns on the main switch S10 to clean a space such as a car or a room, the motor 116 sucks air while driving. At this time, the motor lamp 119 that displays the vacuum state is turned on by the operation of the motor 116 to display the vacuum state.

  In this case, the suction force is transmitted to the foreign matter suction port 132 by the suction hose 120 whose one side is coupled to the suction port 114 and the other side is connected to the substance discharge port 134 to suck the foreign matter.

  The foreign matter sucked in this way flows into the main body 110 and is collected in the dust collection box 160.

  Here, normally, the suction hose 120 is used by being coupled to the foreign matter discharge port 134. However, in order to remove foreign matter between the places where the suction portion 130 cannot enter or the gap, the suction hose 120 is connected to the foreign matter discharge port 134. Use after unbonding.

  When the suction hose 120 is coupled to the foreign matter discharge port 134, the switch moves in the moving space 126 by the switch protrusion 122 of the suction hose 120 and connects the − terminal 125 and the + terminal 127, whereby the brush motor 142. Is driven. At this time, the brush motor 144 is driven and the brush lamp 143 is turned on to indicate that it is in a vacuum state.

  On the other hand, when the suction hose 120 is released from the foreign matter discharge port 134, the switch of the switch protrusion 122 of the suction hose 120 moves through the moving space 126, and the connection between the negative terminal 125 and the positive terminal 127 is released. And the operation of the brush 140 is stopped. At this time, the brush lamp 143 is turned off.

  When the main switch S10 is turned on, power is applied to the ultraviolet lamp 150, and the ultraviolet lamp 150 is attached to sterilize and kill insects. At this time, an ultraviolet ray operation lamp 155 for indicating the operation of the ultraviolet ray lamp 150 is turned on.

  After use, when the dust collection box 160 is full of foreign matter, the coupling of the fastening portion can be released and the foreign matter can be easily discarded.
