Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaners, specifically to a vacuum cleaner that can absorb water. Background Technology

[0002] A vacuum cleaner is a household appliance that uses a suction device to create negative air pressure inside a sealed casing to suck up dust and debris.

[0003] However, in real-world applications, vacuum cleaners often pick up liquids along with dust. To enable vacuum cleaners to pick up liquids, vacuum cleaners with liquid storage chambers have appeared on the market. However, it is difficult to pour out the liquid in the storage chamber. Alternatively, some vacuum cleaners that can automatically discharge liquids may cause accidental contamination of the external environment due to the uncontrollable location of the liquid discharge.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a water-absorbing vacuum cleaner. By setting a drain switch, the user can actively and controllably control the liquid in the storage chamber to be discharged outward. The operation is simple, and at the same time, it avoids the situation where sewage accidentally pollutes the external environment due to the uncontrollable position of the liquid discharge.

[0006] The purpose of this utility model is achieved as follows:

[0007] A water-absorbing vacuum cleaner includes a main body with a liquid storage chamber for storing liquid inside. The liquid storage chamber has a drain outlet for discharging the liquid. The drain outlet is connected to a drain switch. The drain switch has a conducting state that allows the liquid in the liquid storage chamber to be discharged outward and a blocking state that prevents the liquid in the liquid storage chamber from being discharged outward. The drain switch can switch back and forth between the conducting state and the blocking state.

[0008] The drain outlet is located at the bottom center of the liquid storage chamber. The drain outlet is connected to a drain pipe. The front and rear sections of the drain pipe are arranged vertically and horizontally respectively. The front section of the drain pipe is connected to the drain outlet, and the drain switch is located at the rear section of the drain pipe.

[0009] The drain outlet and the drain pipe are detachably connected to each other via a threaded structure.

[0010] The drain switch is spherical in shape. The drain pipe has a corresponding switch cavity. The drain switch is located in the switch cavity and has a through hole. The drain switch can be rotated in the forward direction to make the axis of the through hole coincide with the axis of the rear section of the drain pipe to form a conductive state. Alternatively, the drain switch can be rotated in the reverse direction to make the axis of the through hole perpendicular to the inner wall of the drain pipe to form a cut-off state.

[0011] The upper side of the drain switch is provided with an upwardly extending switch limiting part, which is cylindrical in shape. The upper side of the rear section of the drain pipe is provided with a limiting sleeve corresponding to the switch limiting part. The drain switch can rotate around the center of the switch limiting part in either the forward or reverse direction.

[0012] The switch limiting part is connected to a switch handle. The switch handle and the switch limiting part are detachable and can be fixed together by screws.

[0013] The switch handle is provided with a limiting protrusion, and the limiting sleeve is provided with a limiting concave step corresponding to the limiting protrusion. When the drain switch is in the conducting state and the cut-off state, the limiting protrusion abuts against the circumferential beginning end and circumferential end end of the limiting concave step, respectively.

[0014] An air inlet is provided on the outer side of the main body, and an electrical cavity is provided inside the main body at a position corresponding to the liquid storage cavity above it. An exhaust device is provided inside the electrical cavity to generate negative pressure at the air inlet.

[0015] A filter screen is provided between the air inlet and the air outlet of the exhaust device, and the electrical cavity is formed between the inner side of the filter screen and the main body.

[0016] The beneficial effects of this utility model are:

[0017] By setting a drain switch, users can actively and controllably control the discharge of liquid from the storage chamber. The operation is simple, and at the same time, it avoids the situation where sewage accidentally pollutes the external environment due to the uncontrollable location of liquid discharge.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See Figures 1-10 This vacuum cleaner, capable of absorbing water, includes a main body 1. The main body 1 has a liquid storage chamber 11 for storing liquid. The liquid storage chamber 11 has a drain outlet 12 for discharging the liquid. The drain outlet 12 is connected to a drain switch 2. The drain switch 2 has a conducting state that allows the liquid in the liquid storage chamber 11 to be discharged outwards and a blocking state that blocks the liquid in the liquid storage chamber 11 from being discharged outwards. The drain switch 2 can switch back and forth between the conducting state and the blocking state. By setting the drain switch 2, the user can actively and controllably control the liquid in the liquid storage chamber 11 to be discharged outwards. The operation is simple, and at the same time, it avoids the situation where sewage accidentally pollutes the external environment due to the uncontrollable position of the liquid discharge.

[0030] Furthermore, the drain outlet 12 is located at the bottom center of the liquid storage chamber 11, which can reduce the chance of liquid remaining in the liquid storage chamber 11 when the liquid is discharged outward.

[0031] The drain outlet 12 is connected to the drain pipe 3. The front and rear sections of the drain pipe 3 are arranged vertically and horizontally respectively. The front section of the drain pipe 3 is connected to the drain outlet 12. The drain switch 2 is located at the rear section of the drain pipe 3. The drain pipe 3 can make the drain switch 2 relatively far away from the drain outlet 12 and relatively close to the outer edge of the main body 1, so that the user can operate the drain switch 2 more easily.

[0032] Furthermore, the drain outlet 12 and the drain pipe 3 are detachably connected to each other through a threaded structure, and the drain pipe 3 can be processed as an independent component, which simplifies the processing technology of the main body 1 and the drain pipe 3.

[0033] Furthermore, the drain switch 2 is spherical in shape, and the drain pipe 3 has a switch cavity corresponding to the drain switch 2. The drain switch 2 is set in the switch cavity and has a through hole 21. The drain switch 2 can be rotated in the forward direction to make the axis of the through hole 21 coincide with the axis of the rear section of the drain pipe 3 to form a conductive state, or the drain switch 2 can be rotated in the reverse direction to make the axis of the through hole 21 perpendicular to the inner wall of the drain pipe 3 to form a cut-off state. The structure of the drain switch 2 is simple, and the effect of switching back and forth between the conductive state and the cut-off state can be achieved by simple rotational movement.

[0034] like Figures 1-4 As shown, when the drain switch 2 is in the conducting state, the liquid in the storage chamber 11 can be discharged outward in sequence through the drain port 12, the drain pipe 3 and the through hole 21 of the drain switch 2.

[0035] like Figures 5-10 As shown, when the drain switch 2 is in the cut-off state, the liquid in the storage chamber 11 can only flow to the position of the drain switch 2, and the liquid cannot pass through the drain switch 2 at this time.

[0036] Furthermore, the upper side of the drain switch 2 is provided with an upwardly extending switch limiting part 22, which is cylindrical in shape. The upper side of the rear section of the drain pipe 3 is provided with a limiting sleeve 31 corresponding to the switch limiting part 22. The drain switch 2 can rotate around the center of the switch limiting part 22 in the forward or reverse direction, so that the drain switch 2 can maintain the stability of the rotating shaft during rotation and improve the accuracy of the drain switch 2 in controlling the water flow.

[0037] Furthermore, the switch limit part 22 is connected to the switch handle 23. The switch handle 23 and the switch limit part 22 are detachable and can be fixed by screws, making it easier for users to control the operation of drainage.

[0038] Furthermore, the switch handle 23 is provided with a limiting protrusion 231, and the limiting sleeve 31 is provided with a limiting concave step 311 corresponding to the limiting protrusion 231. When the drain switch 2 is in the conducting state and the cut-off state, the limiting protrusion 231 abuts against the circumferential head end and circumferential end end of the limiting concave step 311 respectively, thereby improving the accuracy of the user's control of the drain switch 2 and allowing the drain switch 2 to be fixed in the preset position.

[0039] Furthermore, an air inlet 13 is provided on the outer side of the main body 1, and an electrical cavity 14 is provided inside the main body 1 at a position above the liquid storage cavity 11. An exhaust device 4 is provided inside the electrical cavity 14 to generate negative pressure in the air inlet 13, so that liquid and dust can fall downward into the liquid storage cavity 11 under the action of gravity.

[0040] Furthermore, a filter screen 5 is provided between the air inlet end of the exhaust device 4 and the air inlet 13. The electrical cavity 14 is formed between the inner side of the filter screen 5 and the main body 1. The filter screen 5 can further reduce the chance of dust and liquid entering the electrical cavity 14, thus providing better protection for the exhaust device 4.

[0041] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
