second block pieces

33, 43, respectively. When one top piece 47 is positioned on the second blocking piece 43, the second outlet 42 is positioned on the top nozzle 46, a top hole 48 for penetrating through the top piece 47 is formed in the top nozzle 46, the first valve body 3 and the second valve body 4 can be close to each other at the moment, the top nozzle 46 is inserted towards the first inlet 31 of the first valve body 3, the top nozzle 46 is abutted against the first blocking piece 33 at the first inlet 31, the elastic force of the first blocking piece 33 is overcome, the first blocking piece 33 is enabled to release the blocking of the first inlet 31, and the first inlet 31 is opened.

The top member 47 may be a cylinder, prism or other protrusion 44 with a propping function. To this end, the second outlet 42 of the top nozzle 46 enters the inner cavity of the first valve body 3 along the first inlet 31, so that the first inlet 31 and the second outlet 42 are communicated.

Since the elastic force of the first blocking member 33 is overcome, the first blocking member 33 may release the sealing of the first inlet port 31, so that the first inlet port 31, the inner cavity of the first valve body 3, and the first outlet port 32 are switched to passages. When the elastic force of the second blocking member 43 is overcome, the second blocking member 43 may release the sealing of the second outlet 42, so that the second inlet 41, the inner cavity of the second valve body 4, and the second outlet 42 are switched to a passage. Therefore, when the first valve body 3 and the second valve body 4 are assembled with each other, a passage is formed between the first valve body 3 and the second valve body 4, and a liquid substance or a gaseous substance is allowed to flow through the first valve body 3 and the second valve body 4. After the first valve body 3 and the second valve body 4 are separated from each other, the first valve body 3 and the second valve body 4 can be automatically switched to an open circuit state, so that a communication device formed by the first valve body 3 and the second valve body 4 has a connection function and an on-off control function at the same time, and the use is more convenient.

At this time, the first inlet port 31 and the first shaft hole 333 may be oppositely disposed at both ends of the first valve body 3, and the first outlet port 32 may be disposed at a side wall of the first valve body 3.

When the first plunger 332 is pressed, the first plunger 332 is pressed by the force, the first spring 334 overcomes the elastic force applied to the first plunger 332 by the first spring 334, the first plunger 331 moves axially along the first axial hole 333, and the first plunger 332 moves away from the first inlet 31 along with the movement of the first plunger 331, so that the first inlet 31 is unblocked, the first inlet 31, the inner cavity of the first valve body 3, and the first outlet 32 are switched to be a passage, and a liquid substance or a gas substance is allowed to flow. The sliding fit between the first plunger 331 and the first shaft hole 333 can also guide the axial movement of the first plunger 332, so as to ensure that the first plunger 332 can stably block and open the first inlet 31 during the movement.

Referring to fig. 4 to 13, the second blocking member 43 includes a second top pillar 431 and a second plunger 432, a second shaft hole 433 communicating with an inner cavity of the second valve body 4 is opened on the second valve body, one end of the second top pillar 431 is slidably inserted into the second shaft hole 433, and the other end is connected to the second plunger 432; the second top pillar 431 is sleeved with a second spring 434, and the second spring 434 applies an elastic force to the second plunger 432 to press against the second outlet 42. At this time, the second outlet 42 and the second shaft hole 433 may be oppositely disposed at both ends of the second valve body 4, and the second inlet 41 may be disposed at a sidewall of the second valve body 4.

When the second plunger 432 is pressed, the second plunger 432 presses the second spring 434 due to the force, the second plunger 431 axially moves along the second shaft hole 433 against the elastic force applied to the second plunger 432 by the second spring 434, and at this time, the second plunger 432 moves away from the second outlet 42 along with the movement of the second plunger 431, so that the second outlet 42 is unblocked, and the second inlet 41, the inner cavity of the second valve body 4 and the second outlet 42 are switched to be a passage, so that a liquid substance or a gas substance is allowed to flow. The sliding fit between the second plunger 431 and the second shaft hole 433 can also guide the axial movement of the second plunger 432, and the second outlet 42 can be stably blocked and opened by the second plunger 432 in the movement process.

With continued reference to fig. 4 to 13, when the first valve body 3 and the second valve body 4 are assembled with each other, since the elastic force of the first plunger 332 is overcome, the first plunger 332 can release the seal of the first inlet port 31, so that the first inlet port 31, the inner cavity of the first valve body 3, and the first outlet port 32 are switched to passages. After the elastic force of the second plunger 432 is overcome, the second plunger 432 may release the sealing of the second outlet 42, so that the second inlet 41, the inner cavity of the second valve body 4, and the second outlet 42 are switched to be a passage. Therefore, when the first valve body 3 and the second valve body 4 are assembled with each other, a passage is formed between the first valve body 3 and the second valve body 4, and a liquid substance or a gaseous substance is allowed to flow through the first valve body 3 and the second valve body 4. After the first valve body 3 and the second valve body 4 are separated from each other, the first valve body 3 and the second valve body 4 can be automatically switched to an open circuit state, so that a communication device formed by the first valve body 3 and the second valve body 4 has a connection function and an on-off control function at the same time, and the use is more convenient. It should be noted that, although fig. 6 to 13 show that the second valve body 4 is first conducted and the first valve body 3 is then conducted in the process of matching the first valve body 3 and the second valve body 4, the present invention is not limited thereto, and the first valve body 3 may be first conducted and the second valve body 4 may be then conducted.

Through research on the existing cleaning equipment, the existing cleaning equipment is generally provided with the water tank 1, the water tank 1 can provide clean water for the floor-washing brush head 14 in the floor-washing process so as to achieve a better cleaning effect, and when the clean water in the water tank 1 is exhausted, a user is required to replenish the clean water to the water tank 1. The water tank 1 is generally provided with only one opening connected with the brush head 14, the opening can only supply clean water in the water tank 1 to the brush head 14 so as to assist the brush head 14 in cleaning in the floor washing process, and the brush head 14 is connected with the opening at any time, so that water cannot be supplemented to the water tank 1 through the opening.

Therefore, in order to provide the water tank 1 of the cleaning device with the function of automatically replenishing clean water, a separate opening must be formed in the water tank 1, and the water replenishing base station 2 is abutted by the separately formed opening. The opening is generally used only when water is replenished, is not used in other states, has low utilization rate, ensures that the opening has enough sealing when not used, otherwise causes the leakage of clear water in the water tank 1, and provides inconvenience for users. Therefore, the single opening will also increase the difficulty of the structural design and the production cost.

In order to realize the automatic water replenishing function of the water tank 1 without independently arranging an additional opening on the water tank 1, the invention provides the following technical scheme, and the communication device can be applied to the cleaning device to be matched with water replenishing.

As shown in fig. 14, the cleaning device provided by the present embodiment includes a water tank 1, where the water tank 1 is provided with only one water passing opening 11; the cleaning device also comprises a pipeline 12, wherein one end of the pipeline 12 is communicated with the water passing port 11, and the other end of the pipeline 12 is connected with a brush head 14; the cleaning apparatus further comprises a first fluid controller 122, the first fluid controller 122 being mounted on the pipeline 12; the cleaning device further comprises a second fluid controller 123, a water replenishing port 121 is formed in the pipeline 12, the water replenishing port 121 is located between the first fluid controller 122 and the water passing port 11, and the second fluid controller 123 is connected with the water replenishing port 121.

Therefore, the water tank 1 can realize water supply and automatic water supplement through only one water passing opening 11 without additionally arranging other openings. However, the present invention is not limited thereto, and the water tank 1 may be further opened with other openings for adding detergent or manually supplementing water, so as to provide more choices for users.

As can be seen from fig. 14, the water tank 1 of the cleaning device is provided with a water outlet 11, the water outlet 11 can be connected with the brush head 14 through a pipeline 12, when the brush head 14 performs cleaning operation on the ground, clean water in the water tank 1 is input to the brush head 14 through the pipeline 12, and the cleaning operation of the brush head 14 is assisted. In order to realize the water replenishing function through the water passing port 11 on the water tank 1, a water replenishing port 121 is further opened on the pipeline 12 connected with the water passing port 11, wherein the first fluid controller 122 can control the connection or disconnection of the pipeline 12, the water replenishing port 121 is arranged between the first fluid controller 122 and the water passing port 11, and the second fluid controller 123 is connected with the water replenishing port 121 to control the connection or disconnection of the water replenishing port 121.

Referring to fig. 16, when the cleaning device is in a cleaning state, the second fluid controller 123 may be closed, and the second fluid controller 123 may disconnect the water replenishing port 121, so that the water replenishing port 121 is in an open state, and clean water cannot flow through. Meanwhile, the first fluid controller 122 is opened, so that the water passing port 11 is only communicated with the first fluid controller 122 through the pipeline 12, and at this time, the clean water in the water tank 1 can only flow to the brush head 14 through the pipeline 12 and cannot pass through the second fluid controller 123, so that the cleaning device can perform normal cleaning operation.

Referring to fig. 17, when the cleaning device is in the water replenishing state, the second fluid controller 123 may be connected to a water replenishing source, which may be a dedicated water replenishing base station 2, a tap water pipe, or other devices capable of replenishing a water source, and a person skilled in the art may select the water replenishing source according to needs, which is not limited herein. At this time, the first fluid controller 122 is closed, and the second fluid controller 123 is opened again, so that the water passing port 11 is only communicated with the second fluid controller 123 and the water replenishing source through the pipeline 12, at this time, the pipeline 12 is disconnected by the first fluid controller 122, and the water tank 1 and the brush head 14 cannot be communicated, so that the water from the water replenishing source can flow to the water tank 1 along the pipeline 12 through the second fluid controller 123, and the water replenishing operation is performed on the water tank 1.

Therefore, the water tank 1 of the cleaning device forms a flow channel structure capable of realizing water outlet or water inlet through the water passing holes through the first fluid controller 122, the second fluid controller 123 and the pipeline 12, the cleaning mode and the water supplementing mode are switched by controlling the on-off of the first fluid controller 122 and the second fluid controller 123, an additional opening does not need to be formed in the water tank 1, and the hidden danger of water leakage of the water tank 1 is solved.

As can be seen with reference to fig. 14 and 19, the cleaning device further comprises a water replenishing base station 2, wherein the water replenishing base station 2 is provided with a water outlet 21; the cleaning device further comprises a third fluid controller 22, said third fluid controller 22 being connected to said water outlet 21. This moisturizing basic station 2 can regard as the moisturizing source to 1 moisturizing of water tank, and moisturizing basic station 2 can be according to factors pertinence configuration such as cleaning equipment's service environment, user demand, and if this cleaning equipment is small-size domestic appliance, what moisturizing basic station 2 can set up is suitable for the family and puts, for example moisturizing basic station 2 is the moisturizing case, and the moisturizing case can conveniently be placed at home, delivery port 21 is seted up on the moisturizing case. If the cleaning equipment is a large commercial electric appliance, the water replenishing base station 2 can enlarge the water storage capacity, increase the volume of the water replenishing tank and be suitable for long-time work, and technicians in the field can select the size and the equipment structure of the water replenishing base station 2 according to requirements without limitation.

Further, the cleaning device further comprises a first water pipe 13, and the second fluid controller 123 is communicated with the water replenishing port 121 through the first water pipe 13; the cleaning device further comprises a second water pipe 23, and the third fluid controller 22 is communicated with the water outlet 21 through the second water pipe 23. The first water pipe 13 may be connected to the second fluid controller 123, so that the second fluid controller 123 is connected to the water replenishing port 121 through the first water pipe 13 at a proper angle and position, and controls the connection and disconnection of the water replenishing port 121 by controlling the connection and disconnection of the first water pipe 13. The second water pipe 23 may be connected to the third fluid controller 22, so that the third fluid controller 22 is connected to the water outlet 21 through the second water pipe 23 at a proper angle and position, and the connection and disconnection of the water outlet 21 are controlled by controlling the connection and disconnection of the second water pipe 23.

The first fluid controller 122, the second fluid controller 123, and the third fluid controller 22 may employ the same control means as the first fluid controller 122, the second fluid controller 123, and the third fluid controller 22, and the first fluid controller 122, the second fluid controller 123, and the third fluid controller 22 may employ different control means as the same. The first fluid controller 122, the second fluid controller 123 and the third fluid controller 22 are required to have at least on-off control function, so that the cleaning device can be switched between the cleaning mode and the water replenishing mode through the respective on-off control functions.

For example, the first fluid controller 122, the second fluid controller 123, and the third fluid controller 22 may each employ a fluid valve. In this case, the fluid valve has only a fluid on-off control function and no fluid driving control function, so that a predetermined flow control between fluids can be achieved according to the gravity action and other ways, which are not limited herein. When the second fluid controller 123 and the third fluid controller 22 both adopt fluid valves, the second fluid controller 123 and the third fluid controller 22 can be replaced by a first valve body 3 and a second valve body 4 which can be matched with each other, and the first valve body 3 and the second valve body 4 are matched to form a communication device which can realize automatic connection and automatic disconnection.

In this case, according to the process of fitting the first valve body 3 and the second valve body 4 shown in fig. 5 to 13, it is preferable that the second valve body 4 which is first opened serves as the second fluid controller 123 and the first valve body 3 which is then opened serves as the third fluid controller 22. Like this, when first valve body 3 switches on, the water in the moisturizing basic station 2 can directly get into water tank 1 through the second valve body 4 that switches on, and then avoids revealing of water.

For example, the first fluid controller 122, the second fluid controller 123 and the third fluid controller 22 may be electromagnetic pumps, which not only have an on-off control function, but also can control the speed of the fluid to drive the fluid to flow rapidly in a predetermined direction, so that when the cleaning device is in a cleaning state, the second fluid controller 123 may be closed to make the water replenishing port 121 in an off state, and no clean water can flow through. Meanwhile, the first fluid controller 122 is opened, so that the water passing port 11 is communicated with only the first fluid controller 122 through the pipeline 12, and clean water in the water tank 1 is driven to flow to the brush head 14 through the pipeline 12 by the first fluid controller 122.

When the cleaning equipment is in a water replenishing state, the second fluid controller 123 can be connected with a water replenishing source, the first fluid controller 122 is closed, meanwhile, the second fluid controller 123 is opened again, so that the water passing port 11 is only communicated with the second fluid controller 123 and the water replenishing source through the pipeline 12, at this time, the pipeline 12 is disconnected by the first fluid controller 122, the water tank 1 and the brush head 14 cannot be communicated, and the water in the water replenishing source is driven to flow to the water tank 1 along the pipeline 12 by the second fluid controller 123 to perform a water replenishing operation on the water tank 1. Of course, if the second fluid controller 123 is connected to the third fluid controller, the third fluid controller 22 may also be used to drive the water from the water replenishment source along the line 12 to the water tank 1 to replenish the water tank 1.

Further, the fluid controller includes a fluid valve and a fluid pump. In order to provide the fluid on-off control function and the fluid-driven control function, the solenoid pumps used as the first fluid controller 122, the second fluid controller 123, and the third fluid controller 22 may also be combined by two components of a fluid valve and a fluid pump. The type and style of the fluid valve and the fluid pump may be set according to requirements, and are not limited herein.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
