Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machines, in particular to a water spraying device and a fabric cleaning machine. Background Art

[0002] A fabric cleaning machine generally consists of a main body, a high-pressure water spraying system, a rotating brush system, a suction motor, a housing, etc. The high-pressure water spraying system controls high-pressure water flow through an electronic button to mix a cleaning agent and water and then spray it on the fabric surface. The rotating brush system brushes off stains and dust on the fabric surface, and the suction motor sucks away the stains and dust through strong suction. Among them, the rotating brush head system is connected to the main body by a long hose, and the electronic button is generally arranged near the rotating brush system end. This setting method requires long-distance wiring of signal lines, and in many cases, it is restricted by the wire length, having problems such as complex technology, unstable performance, and high cost.

[0003] A water spraying window cleaner disclosed in the Chinese utility model patent with the authorization announcement number of CN201039964Y includes a window brush and a handle. A cleaning material is provided on the cleaning surface of the window brush. A water spraying device including a water storage cavity, a nozzle, and a water spraying switch is provided on the handle. During use, when pressing down the control button, the piston moves downward, and the air in the "T"-shaped channel is pressed into the water outlet conduit through the water outlet one-way valve and then discharged from the nozzle; when releasing the control button, the piston drives the control button to return to the initial position under the action of the spring. During this process, negative pressure will be generated in the "T"-shaped channel, so that the water in the water storage cavity is pressed into the "T"-shaped channel through the water inlet conduit and the water inlet one-way valve. Repeating the above actions, when the original air in the "T"-shaped channel and the water outlet conduit is exhausted, water starts to be sprayed from the nozzle. Although the above water spraying window cleaner can solve problems such as complex technology, unstable performance, and high cost, however, since the above water spraying window cleaner needs to be repeatedly pressed to achieve water spraying, the operation is relatively cumbersome and the water spraying efficiency is low. Summary of the Utility Model

[0004] In order to overcome the disadvantages and deficiencies existing in the prior art, the utility model provides a water spraying device and a fabric cleaning machine.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides a water spraying device, including:

[0007] A seat body, the seat body has a water inlet flow channel, a communication flow channel, and a water outlet flow channel. The water inlet end of the water inlet flow channel is used to communicate with a water supply device. The communication flow channel communicates the water outlet end of the water inlet flow channel and the water inlet end of the water outlet flow channel. The water outlet end of the water outlet flow channel is used to communicate with a nozzle;

[0008] A first seal, which is arranged in the communication flow channel;

[0009] A plugging member, which is movably arranged on the seat body. The plugging member has a closed position for cooperating with the first seal to close the communication flow channel and an open position spaced from the first seal to open the communication flow channel. The plugging member moves to switch between the closed position and the open position; and

[0010] An elastic member, one end of which is connected to the seat body and the other end of which is connected to the plugging member. The elastic member is used to provide a driving force for the plugging member to maintain the closed position.

[0011] The water spraying device of the present utility model includes a seat body, a first seal, a plugging member and an elastic member. Among them, the movement of the plugging member can be controlled by a single-point pressing method. The plugging member moves to overcome the driving force of the elastic member, so that the plugging member switches from the closed position to the open position, thereby connecting the water inlet flow channel and the water outlet flow channel through the communication flow channel, enabling the water liquid output by the water supply device to be sprayed out through the nozzle. When water spraying is not required, the plugging member is released, and the elastic member resets to provide a driving force for the plugging member, so that the plugging member switches from the open position to the closed position to stop water spraying. Among them, since the water spraying can be realized by controlling the movement of the plugging member by a single-point pressing method, the water spraying operation is simpler and more convenient, and the water spraying efficiency can be greatly improved.

[0012] In one embodiment, among the seat body and the plugging member, one has a plurality of gear positioning grooves arranged at intervals along the moving direction of the plugging member, and the other is provided with a gear positioning protrusion. The gear positioning protrusion can cooperate with any one of the gear positioning grooves to play a role in positioning the distance between the plugging member and the first seal during the process of moving the plugging member from the closed position to the open position, and the distance between the plugging member and the first seal can be adjusted between multiple gears, so that the water spraying flow rate can be adjusted. In addition, when the plugging member is switched from the open position to the closed position, the plugging member can be pressed to reset to the closed position under the action of the elastic member, and the operation is simple and convenient.

[0013] In one embodiment, the seat body further has a guiding channel extending along the moving direction of the plugging member. The guiding channel communicates with the communication flow channel, and a part of the plugging member cooperates with the guiding channel to play a role in guiding the movement of the plugging member, making the movement of the plugging member more stable and smooth.

[0014] In one embodiment, the plugging member is provided with a plugging portion, a first connecting portion and a linkage portion. The plugging portion and the linkage portion are respectively disposed at two ends of the first connecting portion. The plugging portion has the closed position and the open position. The first connecting portion cooperates with the guiding channel and passes through the central hole of the first seal. The linkage portion is located outside the seat body. In this way, by pressing the linkage portion, the first connecting portion can be driven to move in the guiding channel, so as to drive the plugging portion to switch between the closed position and the open position. This plugging member has a simple and practical structure, high reliability and low cost, which is beneficial to reducing the cost of the water spraying device and is more conducive to the popularization and application of the water spraying device.

[0015] In one embodiment, a second seal is provided on the outer peripheral wall of the first connecting portion. The second seal is clamped between the outer peripheral wall of the first connecting portion and the inner wall of the guiding channel to seal the gap between the first connecting portion and the guiding channel, preventing the water liquid in the communicating flow channel from leaking to the outside of the housing through the gap between the first connecting portion and the guiding channel, thus playing a role in preventing water leakage.

[0016] In one embodiment, the outer diameter of the plugging portion is smaller than the inner diameter of the guiding channel;

[0017] The communicating flow channel includes a first channel section and a second channel section. The water inlet end of the first channel section communicates with the water outlet end of the water inlet flow channel. The first channel section accommodates the first seal. The water inlet end of the second channel section communicates with the water outlet end of the first channel section. The inner diameter of the second channel section is smaller than that of the first channel section to form a limiting end face, and the limiting end face abuts against the first seal;

[0018] The seat body further has an installation opening, and the installation opening communicates with the first channel section. The installation opening is used for the first seal to enter and exit the first channel section;

[0019] The water spraying device further includes:

[0020] An end cover, the end cover is disposed on the seat body, and the end cover covers the installation opening. In this way, during installation, the first seal can be first inserted into the first channel section through the installation opening, and then the end cover is disposed on the seat body to realize the reliable installation of the first seal on the seat body. Then, the elastic member and the second seal are pre-installed on the plugging member. Then, the plugging portion can pass through the guiding channel and push the first seal to deform when approaching the first seal so that it can pass through the central hole of the first seal until the plugging portion is located on the side of the first seal away from the limiting end face, which is convenient for quickly installing the plugging member on the seat body, greatly reducing the installation difficulty of the first seal and the plugging member, and making the installation operation simpler and more convenient.

[0021] The present utility model provides a fabric cleaning machine, including:

Among them, the water pump can be used to keep the water in the water circuit among the water pump, the seat body and the nozzle at a certain pressure. Then, in cooperation with the clutch-type mechanical water spraying device composed of the seat body, the first sealing member, the plugging member and the elastic member, the movement of the plugging member is controlled in a single-point pressing manner. The plugging member moves to overcome the driving force of the elastic member, so that the plugging member is switched from the closed position to the open position, thereby connecting the water inlet flow channel and the water outlet flow channel through the communication flow channel, so that the water pumped out by the water pump can be sprayed out through the nozzle. When water spraying is not required, the plugging member is released, and the elastic member resets to provide a driving force for the plugging member, so that the plugging member is switched from the open position to the closed position to stop water spraying. Among them, since the movement of the plugging member is controlled by a single-point pressing manner to realize water spraying, the water spraying operation is simpler and more convenient, and the water spraying efficiency can be greatly improved.

[0026] In one embodiment, the housing includes:

[0027] A housing main body, the housing main body has an inner cavity and an avoidance opening. The inner cavity houses the water spraying device. The avoidance opening is oppositely arranged with the plugging member, and the avoidance opening communicates the inner cavity with the outside; and

[0028] A water spraying button, the water spraying button is movably arranged on the housing main body along the moving direction of the plugging member.

The movable portion is movably arranged along the moving direction of the plugging member. The second connecting portion and the movable portion are respectively disposed on the left and right sides of the pressing portion, and the distance between the second connecting portion and the pressing portion is greater than the distance between the movable portion and the pressing portion. The pressing portion is connected to the plugging member. Thus, when the pressing portion is pressed, the pressing portion moves to drive the movable portion to move and drive the plugging member to move. Among them, since the distance between the second connecting portion and the pressing portion is greater than the distance between the movable portion and the pressing portion, the water spraying button functions as a lever, thereby making the pressing operation more labor-saving.

[0030] In one embodiment, the housing has a connecting hole located in the inner cavity. The second connecting portion is provided with a connecting protrusion, and the connecting protrusion is snap-fitted with the connecting hole. Thus, by snapping the connecting protrusion into the connecting hole, the second connecting portion can be connected to the housing, and the connecting operation is simple and convenient, which can greatly improve the installation efficiency of the water spraying button.

[0044] The water spraying device of the present utility model includes a seat body 1, a first sealing member 2, a plugging member 3, and an elastic member 4. Among them, the movement of the plugging member 3 can be controlled by a single-point pressing method. The plugging member 3 moves against the driving force of the elastic member 4, so that the plugging member 3 is switched from the closed position to the open position, thereby connecting the water inlet channel 11 and the water outlet channel 13 through the communication channel 12, enabling the water liquid output by the water supply device 8 to be sprayed out through the nozzle 71. When water spraying is not required, the plugging member 3 is released, and the elastic member 4 resets to provide a driving force to the plugging member 3, so that the plugging member 3 is switched from the open position to the closed position, realizing the stop of water spraying. Among them, since the movement of the plugging member 3 can be controlled by a single-point pressing method to achieve water spraying, the water spraying operation is simpler and more convenient, and the water spraying efficiency can be greatly improved.

Among them, the water pump 9 can be used to keep the water in the water circuit between the water pump 9, the seat body 1 and the nozzle 71 under a certain pressure. Then, in cooperation with the clutch-type mechanical water spraying device composed of the seat body 1, the first sealing member 2, the plugging member 3 and the elastic member 4, the movement of the plugging member 3 is controlled in a single-point pressing manner. The plugging member 3 moves to overcome the driving force of the elastic member 4, so that the plugging member 3 is switched from the closed position to the open position. Thus, the water inlet flow channel 11 and the water outlet flow channel 13 are communicated through the communication flow channel 12, so that the water pumped out by the water pump 9 can be sprayed out through the nozzle 71. When water spraying is not required, the plugging member 3 is released, and the elastic member 4 resets to provide a driving force for the plugging member 3, so that the plugging member 3 is switched from the open position to the closed position to stop water spraying.
