Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1 to 4, the cleaning apparatus 100 according to an embodiment of the present utility model mainly includes a first roll brush, a second roll brush, a first water spray module, a second water spray module, and a water supply line assembly. The first roll brush and the first water spray assembly spraying water thereto are disposed at the front end of the cleaning apparatus 100 in the forward direction, so that the first roll brush and the first water spray assembly are the front roll brush 10 and the front water spray module 30, respectively, and the corresponding second roll brush and second water spray module are the rear roll brush 20 and the rear water spray module 40, respectively.

In the prior art, the rear rolling brush has two structures of no water spraying and synchronous water spraying with the front rolling brush, the front rolling brush needs to clean the surface of the rear rolling brush after being used for a period of time, and the rear rolling brush is wet in the front and rear rolling brushes in the working mode, so that the rear rolling brush cannot treat residual water left on the ground by the front rolling brush very well. To solve the above problems, the present embodiment adds a water locking assembly to the water supply line assembly.

The water supply pipeline assembly comprises a water pump 51, a three-way pipe 52 and a water valve seat 53, wherein a water inlet of the water pump 51 is externally connected with water supply equipment, one port of the three-way pipe 52 is communicated with a water outlet of the water pump 51, the other two ports are respectively communicated with the front water spraying module 30 and the rear water spraying module 40 through a first pipeline and a second pipeline, and the water valve seat 53 is communicated between the three-way pipe 52 and the rear water spraying module 40. The water valve seat 53 has a water flow passage therein, and a water lock is provided in the passage. The cleaning apparatus 100 in this embodiment has two states, a cleaning operation state and a self-cleaning operation state, and the water lock has a first state and a second state corresponding to each other. When the water locking piece is in the first state in the cleaning working state, the water locking piece closes the flow passage, at the moment, the front water spraying module 30 is used for supplying water, the rear water spraying module 40 is not used for supplying water, the front rolling brush 10 is used for cleaning the ground, and the rear rolling brush 20 is used for cleaning residual water on the ground; when the water locking piece is in the second state in the self-cleaning working state, the water locking piece opens the flow channel, and at the moment, the front water spraying module 10 and the rear water spraying module 40 are both used for supplying water, so that the surfaces of the front rolling brush 10 and the rear rolling brush 20 can be cleaned.

Specifically, the water valve seat 53 includes a first housing 531 penetrating in an axial direction and a second housing 532 inserted into one end of the first housing 531, wherein the first housing 531 is divided into an upper section and a lower section, and an opening caliber of the second housing 531 is larger than that of the upper half section of the first housing 531. Thus, after the two housings are assembled, a flow passage having one end closed and the middle narrow and two ends wide is formed inside, and a first stepped portion 5311 and a second stepped portion 5312 are formed at the upper and lower ends, respectively. A water lock is placed in the flow channel, comprising a support 533, to the ends of which are secured an upper gasket 534 and a lower gasket 535.

Preferably, the two gaskets are truncated cones, the top diameter of the upper gasket 534 is larger than the caliber of the first step portion 5311, and the bottom diameter is smaller than the caliber of the first step portion 5311, so that the upper gasket 534 is partially embedded when pressed against the first step portion 5311, thereby improving the sealing effect and preventing water leakage.

It is easily conceivable that the lower gasket 535 is similar in that the top diameter is smaller than the diameter of the second stepped portion 5312 and the bottom diameter is larger than the diameter of the second stepped portion 5312, so that the lower gasket 534 is partially embedded when pressed against the second stepped portion 5312, improving the sealing effect and preventing water leakage.

The upper gasket 534 and the lower gasket 535 are preferably made of a flexible material such as rubber, etc., which is deformed to some extent when the state is switched, and the sealing effect is improved by increasing the contact area, preventing water leakage.

The two sealing gaskets are respectively positioned at the two ends of the flow channel, and only one sealing gasket at one end can be abutted against the corresponding step part at the same time. A water outlet is formed in the upper half of the first housing 531, a water inlet is formed in the second housing 532, the water inlet is disposed above the water outlet, and both are disposed on both sides of the water valve seat 53.

The water valve seat 53 has two states of locking and water passing, when the water valve seat is in the locked state, the upper sealing gasket 534 presses against the first step part 5311, and at the moment, water cannot flow out through the water outlet; when in the water-through state, the water-locking member moves upward, the lower gasket 535 is pressed against the second step portion 5312, at this time, the upper gasket 534 is separated from the first step portion 5311, the water inlet and the water outlet are in the communication state, and the water flow flows out through the water outlet.

Further, to increase the restoring function of the water locking member, the second housing 532 is provided with a guide groove 5321, a protrusion 5331 which can be inserted into the guide groove 5321 is provided on the support 533, and a restoring spring 536 is sleeved outside the protrusion 5331 and the guide groove 5321. When switching to the water-on state, return spring 536 compresses and stores energy; when a switch to the locked state is required, the water lock loses support, and the return spring 536 releases the stored energy and drives the water lock to move downward.

It will be appreciated that the positions of the guide slot 5321 and the protrusion 5331 may be interchanged, i.e. the protrusion 5331 protrudes from the bottom of the second housing 532, and the guide slot 5321 is opened on top of the stand 53.

At the same time, the return spring 536 may alternatively be disposed within the guide slot 5321 and abut the top of the projection 5331.

As shown in fig. 1 or 2, the upper gasket 534 and the lower gasket 535 are clamped on the support 533, so that annular protrusions are arranged at two ends of the support 533 to improve the fixing effect, and the inner holes of the gaskets are designed to be wide at the upper part and narrow at the lower part, so that the two gaskets can be fixed at two ends of the support 533 through manual adjustment, and the situation that the upper gasket 534 and/or the lower gasket 535 fail due to follow-up of the upper gasket 534 and/or the lower gasket 535 is avoided.

In this embodiment, a driving structure is provided for the water valve seat 53 to drive the water locking member to move, the driving structure is a charging seat disposed below the water valve seat 53, the charging seat protrudes to have a top block 70, and the top block 70 extends upwards into the first housing 531 and abuts against the support 533. When power needs to be provided to switch to a water-through state, the top block 70 pushes the support 533 upward, pushing the upper gasket 534 away from the first step 5311; when the water-locking state is required to be switched, the top block 70 moves downward, the support 533 moves downward under the action of the return spring 536, and the upper gasket 534 abuts against the first step portion 5311 and seals the flow passage.

Because the bottom of the support 533 needs to bear the acting force of the top block, in order to improve the supporting effect, a wider base is arranged at the bottom of the support 533 to improve the stress effect. And the base is preferably the same as the diameter of the lower section of the first housing 531 to further enhance the waterproof effect.

As shown in fig. 3, the water valve seat 53 is provided with screw holes for fixing bolts, which are fixed to the cleaning apparatus 100 by bolting. Of course, in other embodiments, a snap or other fastening means may be used, and the present embodiment is not limited thereto.

Since the second housing 532 is inserted in the first housing 531 to be rotatable, the direction of the water inlet can be adjusted, and in the case that the first housing 531 cannot be adjusted in position, the water inlet direction can be adjusted by rotating the second housing 532, thereby improving flexibility. Meanwhile, the water valve seat 53 is designed in a split type, so that the inner water locking member is easy to be disassembled and maintained, such as the replacement of the upper gasket 534, the lower gasket 535, the return spring 536, etc.

It should be understood that, since the first housing 531 and the second housing 532 are detachably fixed, attention is paid to waterproof problem, so that the normal operation is prevented from being affected by the water flowing into the cleaning apparatus 100, such as providing a waterproof gasket or applying waterproof glue at the connection between the first housing 531 and the second housing 532. Similarly, in order to further enhance the waterproof effect, it is necessary to waterproof the lower gasket 535 in order to prevent water from flowing out from the lower end of the first housing 531.

It is readily contemplated that the same water locking assembly may be added between tee 532 and front water module 30 when it is desired to add a similar water locking function to the front water spray structure (e.g., the ground itself is wet). At this time, the front rolling brush 10 and the rear rolling brush 20 can be independently switched to a dry-wet state, so that the flexibility is further improved.

As shown in fig. 4, the cleaning apparatus 100 further includes a housing 60 having a fixing space formed therein for fixing the front roll brush 10, the rear roll brush 20, the front water spray module 30, the rear water spray module 40, the water supply line assembly, and the like.

The foregoing descriptions of specific exemplary embodiments of the present utility model are presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the utility model and its practical application to thereby enable one skilled in the art to make and utilize the utility model in various exemplary embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the utility model be defined by the claims and their equivalents.
