Description

Technical Field

[0001] This utility model relates to the field of water system technology, specifically to a water distribution component and a cleaning machine using the water distribution component. Background Technology

[0002] Most current water distribution components are electromagnetic valves or driven by motors. For example, the Chinese invention patent application CN202011635828.6 (publication number CN114688300A) discloses a water distribution valve and a cleaning machine using the water distribution valve. The water distribution valve includes a housing, a fixed base, a movable column, and a drive assembly. The housing has a first drain outlet and a second drain outlet. A partition is vertically arranged in the water distribution chamber to divide it into a first cavity corresponding to the first drain outlet and a second cavity corresponding to the second drain outlet. The bottom of the partition is provided with an opening that connects the first cavity and the second cavity. The top of the movable column is provided with a sealing plug that can close the second drain outlet when it rises to the top of the second cavity and close the opening when it descends to the bottom of the second cavity.

[0003] The drive assembly includes a drive wheel and a drive component. The drive wheel is rotatably mounted below the fixed base. A guide post extending axially and perpendicular to the movable column is provided on the drive wheel. Correspondingly, the lower end of the movable column has a laterally extending guide groove. The guide post of the drive wheel is constrained within the guide groove by reciprocating sliding along it. The drive component is a motor, which rotates the drive wheel, thereby causing the guide post to pull the movable column up and down through the guide groove, thus achieving the alternating opening and closing of the first and second drain outlets.

[0004] This water distribution valve requires electric drive, necessitates additional circuitry, suffers from poor stability, and has a complex drive component structure that occupies a large space. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to provide a water distribution component that does not use electric drive, in light of the current state of the technology.

[0006] The second technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned water separation component, in view of the current state of the prior art.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a water distribution component, characterized in that it includes...

[0008] The water outlet pipe has at least two water outlets spaced apart along its circumference on its peripheral wall;

[0009] The water inlet pipe has an inlet and a outlet, the outlet is located on the periphery of the water inlet pipe, and the part of the water inlet pipe with the outlet is movably inserted into the water outlet pipe.

[0010] The pipe body is fixed relative to the outlet pipe;

[0011] A drive tube is installed in the tube body and can move axially relative to the tube body under the action of air pressure or water pressure. One end face of the drive tube is an undulating wave-shaped end face.

[0012] The movable tube is fixedly connected to the inlet pipe and the two are coaxial. The movable tube is partially inserted into the drive tube. The outer peripheral wall of the movable tube is provided with a protrusion located outside the drive tube. One end face of the protrusion is a bevel. The bevel always abuts against the wavy end face, so that the movable tube can move axially and rotate circumferentially relative to the tube body, thereby driving the inlet pipe to move synchronously, and thus realizing the selective connection between the drain outlet and the outlet.

[0013] The elastic element acts on the movable tube, causing the movable tube to maintain its tendency to move in the direction of the driving tube.

[0014] To facilitate applying force to the drive tube, one end of the drive tube is closed, and the other end is open for insertion of a movable tube. The end face of the open end is wavy. A water pipe or air pipe for applying pressure to the closed end of the drive tube can be inserted into the tube body.

[0015] In order to ensure that the moving tube is subjected to uniform force and can rotate and move smoothly, there are at least two protrusions and they are spaced apart along the circumference of the moving tube.

[0016] In order to ensure the axial movement of the drive tube so that the wavy end face and the inclined surface of the protrusion cooperate, and ultimately the movable tube moves and rotates, a guide structure is provided between the tube body and the drive tube to guide and limit the movement trajectory of the drive tube.

[0017] The guide structure can have various structural forms. In the case of a simple structure, the guide structure includes a guide block and a guide groove for the guide block to slide within it. The guide block is located on the outer peripheral wall of the drive tube, and the guide groove is located on the inner peripheral wall of the tube and extends along its axial direction.

[0018] To ensure circumferential positioning after the drive tube has rotated to its designated position, the protrusion can enter or exit the guide groove. When the protrusion is in the guide groove, the drain outlet and the water outlet are connected. When the protrusion is in the guide groove, the movable tube cannot rotate circumferentially, only axially; when the protrusion is disengaged from the guide groove, the movable tube can rotate circumferentially.

[0019] In the above scheme, the water outlet pipe and the pipe body are inserted and fitted together, the inner wall surface of the water outlet pipe has a limiting part, and the elastic element is a spring, one end of which abuts against the protrusion and the other end of which abuts against the limiting part.

[0020] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a cleaning machine, characterized in that it includes the above-mentioned water separation component.

[0021] Preferably, the cleaning machine includes spray arms that are connected to the water outlets on the water outlet pipe in a one-to-one manner, so as to supply water to different spray arms.

[0022] Compared with the prior art, the advantages of this utility model are: by applying air pressure or water pressure to the drive pipe, the wavy end face and the inclined surface on the protrusion between the drive pipe and the movable pipe enable the movable pipe to move axially and rotate circumferentially, thereby driving the inlet pipe to move synchronously, and thus realizing the selective connection between the drain outlet on the inlet pipe and the outlet on the outlet pipe.

[0023] As can be seen from the above, the water distribution component of this utility model has a simple structure, does not require electric drive, and has high operational reliability. Attached Figure Description

[0034] like Figures 1-7 As shown, the water distribution assembly of this preferred embodiment includes an outlet pipe 1, an inlet pipe 2, a pipe body 3, a drive pipe 4, a movable pipe 5, and an elastic element 6.

[0035] The pipe body 3 is fixed relative to the water outlet pipe 1. In this embodiment, the two are inserted together and internally connected.

[0036] At least two outlets 11 are provided at intervals along the circumference of the peripheral wall of the outlet pipe 1. The inlet pipe 2 has an inlet 21 and a drain 22. The drain 22 is provided on the peripheral wall of the inlet pipe 2, and the part of the inlet pipe 2 with the drain 22 is movably inserted into the outlet pipe 1.

[0037] The drive tube 4 is installed in the tube body 3 and can move axially relative to the tube body 3 under the action of air pressure or water pressure. One end face of the drive tube 4 is an undulating wave-shaped end face 41. In this embodiment, one end of the drive tube 4 is closed and the other end is open for the insertion of the movable tube 5, and the end face of the open end is a wave-shaped end face 41. A water pipe or air pipe for pressurizing the closed end of the drive tube 4 can be inserted into the tube body 3 to apply water pressure or air pressure to the drive tube 4 and push the drive tube 4 to move axially relative to the tube body 3.

[0038] The movable pipe 5 is fixedly connected to the water inlet pipe 2 and the two are coaxial. In this embodiment, the two are connected as one piece, but their interiors are not connected. Water in the water inlet pipe 2 will not enter the movable pipe 5.

[0039] The movable tube 5 is partially inserted into the drive tube 4. The outer peripheral wall of the movable tube 5 has protrusions 51 located outside the drive tube 4. One end face of each protrusion 51 is a bevel 52, which always abuts against the wavy end face 41, allowing the movable tube 5 to move axially and rotate circumferentially relative to the tube body 3. This drives the inlet tube 2 to move synchronously, thereby enabling selective connection between the drain outlet 22 and the outlet 11. To ensure even force distribution on the movable tube 5 and smooth rotation and movement, at least two protrusions 51 are provided, spaced apart circumferentially along the movable tube 5.

[0040] The elastic element 6 acts on the movable tube 5, causing the movable tube 5 to maintain its tendency to move towards the closed end of the drive tube 4. In this embodiment, as... Figure 2 As shown, the inner wall of the water outlet pipe 1 has a limiting part 12, and the elastic element 6 is a spring, one end of which abuts against the protrusion 51 and the other end of which abuts against the limiting part 12.

[0041] A guide structure is provided between the tube body 3 and the drive tube 4 to allow the drive tube 4 to move along its axial direction, so as to guide and restrict the movement trajectory of the drive tube 4, and ensure that the drive tube 4 moves axially so that the wavy end face 41 and the inclined surface 52 of the protrusion 51 cooperate, ultimately allowing the movable tube 5 to move and rotate.

[0042] In this embodiment, the guiding structure includes a guide block 42 and a guide groove 31 in which the guide block 42 slides, such as Figure 4 As shown, the guide block 42 is provided on the outer peripheral wall of the drive tube 4, and the guide groove 31 is provided on the inner peripheral wall of the tube body 3 and extends along its axial direction. Specifically, at least two protrusions 32 are provided on the inner peripheral wall of the tube body 3 at intervals along its circumference. Each protrusion 32 extends along the axial direction of the tube body 3, and a guide groove 31 is formed between two adjacent protrusions 32.

[0043] In addition, such as Figure 3 As shown, the protrusion 51 can enter or exit the guide groove 31. When the protrusion 51 is in the guide groove 31, the drain outlet 22 and the water outlet 11 are connected accordingly. When the protrusion 51 is in the guide groove 31, the movable tube 5 cannot rotate circumferentially, but can only move axially; when the protrusion 51 is out of the guide groove 31, the movable tube 5 can rotate circumferentially.

[0044] The working process of the water distribution component in this embodiment is as follows:

[0045] (1) In the initial state, the protrusion 51 is located in the guide groove 31;

[0046] (2) Apply water pressure or air pressure to the closed end of the drive tube 4. The drive tube 4 moves axially relative to the tube body 3, which drives the movable tube 5 and the water inlet tube 2 to move axially synchronously. The elastic element 6 is compressed. When the movable tube 5 moves axially to the limit position, the protrusion 51 moves out of the guide groove 31 and continues to apply pressure to the drive tube 4. Because the movable tube 5 cannot continue to move axially, under the action of the wavy end face 41 and the inclined surface 52 of the protrusion 51, the movable tube 5 rotates circumferentially, which drives the water inlet tube 2 to rotate circumferentially synchronously until the protrusion 51 faces the next guide groove 31 (relative to the guide groove 31 in the initial state).

[0047] (3) Then, no more water pressure or air pressure is applied to the closed end of the drive pipe 4. At this time, the drive pipe 4, the movable pipe 5, and the water inlet pipe 2 all move axially in the opposite direction under the action of the elastic element 6. The protrusion 51 enters the next guide groove 31 (relative to the guide groove 31 in the initial state). At this time, the drain outlet 22 of the water inlet pipe 2 and one of the outlet outlets 11 of the water outlet pipe 1 are connected. The movable pipe 5 is positioned in the circumferential direction. At the same time, because the external pressure disappears, it is also positioned in the axial direction under the action of the elastic element 6.

[0048] (3) If it is necessary to connect the drain outlet 22 with another outlet 11, repeat the above operations (2) and (3).

[0049] The water distribution component of this embodiment can be used on a cleaning machine, for example, to supply water to different spray arms. The cleaning machine includes spray arms that are connected one-to-one with the water outlets 11 on the water outlet pipe 1, so as to supply water to different spray arms.

[0050] Of course, this water distribution component can also be used in other water circuit parts of the cleaning machine.
