[0010] Each embodiment of the present disclosure will be described in detail below. FIG. 1 is a perspective view of a cleaning device 1 in one non-limiting embodiment. FIG. 2 is a side view of the cleaning device 1 shown in FIG. 1. FIG. 3 is a schematic diagram of the cleaning device 1 shown in FIG. 1. As shown in FIGS. 1 to 3, the cleaning device 1 includes a device main body 10, a hose 20, an extension tube 30, and a nozzle 40. The extension tube 30 and the nozzle 40 are cleaning device units in the cleaning device 1. The cleaning device 1 discharges the cleaning liquid stored in a cleaning liquid tank 11 stored inside the device main body 10 from the nozzle 40 onto a surface to be cleaned. The cleaning device 1 also sucks the discharged cleaning liquid and dirt from the nozzle 40 and stores them in a dirty water tank 12 stored inside the device main body 10. In the following description, the cleaning liquid and dirt sucked from the nozzle 40 may be collectively referred to as dirty water. In FIG. 3, the direction in which the cleaning liquid and dirty water flow in the cleaning device 1 are indicated by arrows. The arrows shown in the direction from the cleaning liquid tank 11 to the nozzle 40 indicate the direction in which the cleaning liquid flows, and the arrows shown in the direction from the nozzle 40 to the wastewater tank 12 indicate the direction in which the wastewater flows. Each part of the cleaning device 1 will be described in detail below.

[0011] The device body 10 houses a cleaning liquid tank 11 and a wastewater tank 12. The device body 10 houses a pump 13 for sending the cleaning liquid stored in the cleaning liquid tank 11 to a nozzle 40 (described later), and a motor 14 for sucking the cleaning liquid and dirt from the nozzle 40.

[0012] The hose 20 has a first end 21 and a second end 22. The first end 21 is connected to the device main body 10. The second end 22 is connectable to an extension tube 30.

[0013] Fig. 4 is an enlarged view of the cleaning device 1 around the location where the hose 20 and the extension tube 30 are connected. Fig. 5 is a cross-sectional view taken along line VV in Fig. 4. As shown in Fig. 5, the hose 20 has a first flow path 23 and a second flow path 24. The first flow path 23 is a flow path that sends the cleaning liquid from the device body 10 to the extension tube 30. The second flow path 24 is a flow path that sends the dirty water sent from the nozzle 40 via the extension tube 30 to the device body 10.

[0014] A switching mechanism 25 for switching the discharge of the cleaning liquid is provided in the first flow path 23 near the second end 22. Fig. 6 is an enlarged view of the switching mechanism 25 in a state in which a first button 26 (described later) is not pressed. As shown in Fig. 6, the switching mechanism 25 includes the first button 26 and a first valve 50.

[0015] The first button 26 is a button for receiving an instruction to discharge the cleaning liquid from a user when pressed. The first button 26 protrudes from the hose 20.

[0016] The first valve 50 is disposed inside the hose 20. The first valve 50 includes a valve body 51, a valve body 52, a spring 53, a first O-ring 54, and a second O-ring 55.

[0017] The valve box 51 is hollow inside. The valve box 51 includes a first protruding portion 51A into which the cleaning liquid sent from the first flow path 23 flows, and a second protruding portion 51B into which the cleaning liquid is discharged from the first valve 50. The second protruding portion 51B is located closer to the first button 26 than the first protruding portion 51A in the direction in which the first button 26 protrudes.

[0018] Valve body 52 is a member that extends in the direction in which first button 26 protrudes. Most of valve body 52 is stored inside valve box 51, and protruding portion 52A protruding from valve box 51 abuts against first button 26. End portion 52B of valve body 52 opposite protruding portion 52A abuts against spring 53. As a result, a pressing force is applied to valve body 52 in the direction toward first button 26.

[0019] The valve body 52 has a small diameter portion 52C formed in the center in the direction in which the first button 26 protrudes, the small diameter portion being smaller than the other portions. The first O-ring 54 and the second O-ring 55 are attached to the valve body 52. ​​The first O-ring 54 is attached to the periphery of the valve body 52 between the protruding portion 52A and the small diameter portion 52C in the direction in which the first button 26 protrudes. The second O-ring 55 is attached to the periphery of the valve body 52 between the end portion 52B and the small diameter portion 52C in the direction in which the first button 26 protrudes. As shown in FIG. 6, when the first button 26 is not pressed, the first O-ring 54 and the second O-ring 55 abut against the inner surface of the valve box 51. In this state, the cleaning liquid that flows into the valve box 51 from the first protruding portion 51A is likely to be blocked by the second O-ring 55. Therefore, the cleaning liquid that has flowed into the valve box 51 from the first protruding portion 51A is less likely to be discharged from the second protruding portion 51B.

[0020] FIG. 7 is an enlarged view of the switching mechanism 25 in a state in which the first button 26 is pressed. As shown in FIG. 7, when the first button 26 is pressed by a user, the valve body 52 moves in the direction in which the button is pressed. This causes the second O-ring 55 to move away from the inner surface of the valve box 51. As a result, the first protrusion 51A and the second protrusion 51B are in communication with each other, and the cleaning liquid that has flowed into the valve box 51 from the first protrusion 51A is discharged from the second protrusion 51B. This allows the cleaning liquid in the first flow path 23 to be sent to the third flow path 32 of the extension tube 30, which will be described later.

[0021] The extension tube 30 is a member for extending the distance between the hose 20 and the nozzle 40. The extension tube 30 can be connected to the hose 20. The extension tube 30 is detachable from the nozzle 40. A detachment mechanism between the extension tube 30 and the hose 20 and a detachment mechanism between the extension tube 30 and the nozzle 40 can use a conventionally known configuration. Therefore, a detailed description of the detachment mechanism will be omitted.

[0022] 5, the extension tube 30 has an inlet 31 through which the cleaning liquid is supplied from the first flow path 23 of the hose 20. The extension tube 30 has an outlet through which the cleaning liquid is discharged. The cleaning liquid discharged from the outlet is supplied to the nozzle 40.

[0023] 5, the extension pipe 30 includes a third flow path 32 and a fourth flow path 33. The third flow path 32 is a flow path that sends the cleaning liquid supplied from the first flow path 23 of the hose 20 to the nozzle 40, and the cleaning liquid flows inside. The third flow path 32 extends from the inlet 31 toward the outlet. The fourth flow path 33 is a flow path that sends the wastewater sent from the nozzle 40 to the hose 20. The extension pipe 30 may be longer than the nozzle 40 in the direction in which the third flow path 32 extends.

[0024] The extension tube 30 is provided with a discharge mechanism 34 that discharges the cleaning liquid present inside the third flow path to the outside when the cleaning liquid is not being supplied from the hose 20. Fig. 8 is an enlarged view of the discharge mechanism 34 in a state where a second button 35 (described later) is not pressed. As shown in Fig. 8, the discharge mechanism 34 includes the second button 35 and a second valve 60.

[0025] When pressed, second button 35 functions as an operation receiving unit for receiving an instruction from the user to drain the cleaning liquid present inside extension tube 30. Second button 35 protrudes from extension tube 30.

[0026] The second valve 60 is disposed inside the extension tube 30. The second valve 60 includes a valve body 61, a valve body 62, a spring 63, a third O-ring 64, and a fourth O-ring 65.

[0027] The valve box 61 is hollow inside. The valve box 61 includes a third protruding portion 61A into which the cleaning liquid sent from the hose 20 flows, and a fourth protruding portion 61B into which the cleaning liquid is discharged from the second valve 60. The third protruding portion 61A and the fourth protruding portion 61B are located at the same height in the direction in which the second button 35 protrudes.

[0028] The valve body 62 is a member that extends in the direction in which the second button 35 protrudes. Most of the valve body 62 is stored inside the valve box 61, and a protruding portion 62A protruding from the valve box 61 abuts against the second button 35. A gap is provided between the protruding portion 62A and the valve box 61. A spring 63 is inserted into an end portion 62B of the valve body 62 opposite the protruding portion 62A. When the second button 35 is not pressed, tension is applied to the valve body 62 by the spring 63 in the direction in which the second button 35 protrudes.

[0029] A third O-ring 64 and a fourth O-ring 65 are attached to the valve body 62. The third O-ring 64 is attached closer to the protruding portion 62A than the third protruding portion 61A and the fourth protruding portion 61B in the direction in which the second button 35 protrudes when the second button 35 is not pressed. Here, as described above, a gap is provided between the protruding portion 62A and the valve box 61. Therefore, in the direction in which the second button 35 protrudes, the space on the side where the second button 35 protrudes from the third O-ring 64 communicates with the external space. When the second button 35 is not pressed, the fourth O-ring 65 is attached closer to the end portion 62B than the third protruding portion 61A and the fourth protruding portion 61B in the direction in which the second button 35 protrudes. As shown in FIG. 8, when the second button 35 is not pressed, the third O-ring 64 and the fourth O-ring 65 abut against the inner surface of the valve box 61. In this state, the cleaning liquid that has flowed in from the third protruding portion 61A passes between the third O-ring 64 and the fourth O-ring 65 and is discharged from the fourth protruding portion 61B.

[0030] FIG. 9 is an enlarged view of the discharge mechanism 34 in a state in which the second button 35 is pressed. As shown in FIG. 9, when the second button 35 is pressed by a user, the valve body 62 moves in the direction of pressing. As a result, the third O-ring 64 moves away from the inner surface of the valve box 61. As described above, the space on the side where the second button 35 protrudes from the third O-ring 64 communicates with the external space. Therefore, when the third O-ring 64 moves away from the inner surface of the valve box 61, the external space is communicated with the third protruding portion 61A and the fourth protruding portion 61B. As a result, the third flow path 32 is communicated with the external space. In this way, when the second button 35 is pressed by a user, communication between the internal space of the third flow path 32 and the external space of the third flow path 32 can be switched.

[0031] Even when the second button 35 is pressed by the user, the third protrusion 61A and the fourth protrusion 61B are in communication with each other. Therefore, regardless of whether the second button 35 is pressed or not pressed by the user, the third protrusion 61A and the fourth protrusion 61B are in communication with each other.

[0032] 1 and 2, the nozzle 40 is connected to the extension tube 30, and the cleaning liquid is supplied from the outlet of the extension tube 30. The nozzle 40 has a discharge hole 41 and a suction port 42. The discharge hole 41 discharges the cleaning liquid supplied from the outlet. The suction port 42 sucks the cleaning liquid discharged from the discharge hole 41 and dust. The nozzle 40 may further have a flow path that delivers the cleaning liquid supplied from the outlet to the discharge hole 41.

[0033] (Example of using cleaning device 1) Next, an example of use of the cleaning device 1 will be described. Before use, the cleaning device 1 is in a state in which the first button 26 and the second button 35 are not pressed. In this state, as shown in FIG. 6, the cleaning liquid that flows into the valve box 51 from the first protruding portion 51A is blocked by the second O-ring 55. Therefore, the cleaning liquid is not supplied to the extension tube 30 and the nozzle 40. When cleaning using the cleaning device 1, the user presses the first button 26. This causes the second O-ring 55 to move away from the inner surface of the valve box 51 as shown in FIG. 7. As a result, the first protruding portion 51A and the second protruding portion 51B are in communication with each other, and the cleaning liquid is sent to the inlet 31 of the extension tube 30. The cleaning liquid sent to the inlet 31 flows through the third flow path 32 and is supplied to the nozzle 40 because the third protruding portion 61A and the fourth protruding portion 61B are in communication with each other. The cleaning liquid supplied to the nozzle 40 is discharged to the outside through the discharge hole 41 and is sucked together with the dust from the suction port 42 .

[0034] Next, the operation after the cleaning by the cleaning device 1 is completed will be described. When the cleaning by the cleaning device 1 is completed, the user releases the pressure on the first button 26. As a result, as shown in FIG. 6, the first O-ring 54 and the second O-ring 55 are in contact with the inner surface of the valve box 51, and the supply of the cleaning liquid to the inlet 31 is stopped. In this state, the space from the point where the second O-ring is in contact with the valve box 51 to the discharge hole 41 of the nozzle 40 is in a communicated state. Hereinafter, this space is referred to as a communication space. In the communication space, only the point where the discharge hole 41 is formed communicates with the external space. Therefore, the atmospheric pressure is applied to the cleaning liquid remaining inside the communication space only from the discharge hole 41 side. As a result, the cleaning liquid remaining inside the third flow path 32 is less likely to be discharged to the outside. In this state, if the extension tube 30 is removed from the hose 20, for example when storing the cleaning device 1, the inlet 31 of the extension tube 30 will be connected to the outside space, and there is a possibility that the cleaning liquid will leak from the outlet hole 41.

[0035] In the cleaning device 1 of the present embodiment, the above problem is solved by providing a discharge mechanism 34. Specifically, before removing the extension tube 30 from the hose 20, the user presses the second button 35 of the discharge mechanism 34 with the extension tube 30 in a position where the outlet is lower than the inlet 31 in the horizontal direction. As a result, as shown in FIG. 9, the third O-ring 64 is separated from the inner surface of the valve box 61, and the communication space and the external space are also in communication at that point. As a result, atmospheric pressure is applied to the cleaning liquid remaining inside the third flow path 32 from the point where the communication space and the external space are in communication, so that the cleaning liquid that was present inside the third flow path 32 can be discharged to the side of the outlet by the weight of the cleaning liquid. The cleaning liquid discharged from the outlet is discharged from the discharge hole 41 via the nozzle 40.

[0036] As described above, the extension tube 30 in this embodiment includes the discharge mechanism 34 that discharges the cleaning liquid present inside the third flow path 32 to the outside when no cleaning liquid is being supplied. This makes it possible to discharge the cleaning liquid present inside the third flow path 32 to the outside before removing the extension tube 30 from the hose 20, for example, when storing the cleaning device 1.

[0037] In the cleaning device 1, the distance between the second button 35 and the hose 20 may be smaller than the distance between the second button 35 and the nozzle 40. This allows the second button 35 to be disposed in a position close to the first button 26, making it easier for the user to control discharge by the discharge mechanism 34.

[0038] The cleaning device 1 of the present disclosure is not limited to a configuration in which the extension tube 30 is provided with the discharge mechanism 34. For example, (1) the cleaning device may have a nozzle 40 as a cleaning device component, (2) the nozzle 40 is connected to the hose 20 and has the discharge mechanism 34 and a discharge hole 41, and (3) the discharge hole 41 functions as an outlet for discharging the cleaning liquid to the outside. In this case, the cleaning device 1 may be composed of the device main body 10, the hose 20, and the nozzle 40. In this case, the cleaning liquid remaining inside the nozzle 40 can be discharged to the outside by the discharge mechanism 34 before removing the nozzle 40 from the hose 20 after cleaning is completed. In both the configuration in which the extension tube 30 has the discharge mechanism 34 and the configuration in which the nozzle 40 has the discharge mechanism 34, the discharge mechanism 34 makes it possible to discharge the cleaning liquid to the outside from the outlet.
