[0070] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0071] The present application provides a cleaning machine water gun handle and a cleaning machine.

[0072] See also Figure 1 , Figure 2 The cleaning machine water gun handle may include a housing 100, a liquid outlet pipe 200 and an inlet valve 300. One end of the inlet valve 300 is used to connect to a water inlet pipe (for example, it can be connected to Figure 2 The lower end of the inlet valve 300 of the perspective view), and the other end is connected to the liquid outlet pipeline 200. The far end of the liquid outlet pipeline 200 can also be connected to a nozzle.

[0073] See also Figure 2 , Figure 3 The cleaning machine water gun handle may further include a suction valve 400, a suction pipe 540 and a check valve 600. One end of the suction valve 400 is connected to the suction pipe 540, and the suction pipe 540 may extend into the liquid storage bottle 500, or the suction pipe 540 may extend into other forms of liquid storage containers (for example, directly into the original container of the medicine or detergent, and the cleaning machine water gun handle may not be connected to the liquid storage bottle 500).

[0074] The other end of the suction valve 400 can be connected to the check valve 600. The check valve 600 is connected to the liquid outlet pipe 200 (for example, it can be connected to the liquid outlet pipe 200 through a connector 700, which will be described later), and the connection position of the check valve 600 and the liquid outlet pipe 200 is located in the housing 100.

[0075] In the present application, the liquid in the liquid storage bottle 500 connected to the liquid storage bottle connection port 530 can enter the liquid outlet pipe 200 through the liquid suction valve 400 and the check valve 600. Different from the external hose in the prior art, the liquid circuit layout is ingenious and highly integrated.

[0076] The applicant has found that when the check valve 600 is not provided and the liquid in the liquid outlet pipe 200 is a high-pressure liquid, the high-pressure liquid easily enters the liquid suction valve 400 and the liquid storage bottle 500, causing backflow. Therefore, the present application provides a check valve 600 to prevent the high-pressure liquid from entering the liquid suction valve 400 and the liquid storage bottle 500 when the high-pressure liquid is discharged, thereby preventing backflow.

[0077] See also Figure 3A connector 700 is provided between the inlet valve 300 and the liquid outlet pipe 200, and the check valve 600 is also connected to the liquid outlet pipe 200 through the connector 700. A first channel 710 with a gradually changing cross-sectional area and a second channel 720 with a constant cross-sectional area can be provided in the connector 700, and the end of the first channel 710 with the smallest cross-sectional area is connected to the second channel 720. The outlet of the check valve 600 is connected to the second channel 720. This structure enables negative pressure to be generated at the connector 700 when water from the inlet valve 300 flows through the connector 700, thereby opening the check valve 600 to absorb liquid. The connector 700 can be a connector with a venturi nozzle structure.

[0078] See also Figure 3 The check valve 600 may include a check valve ball 610. When the liquid in the liquid outlet pipe is in a first pressure range, the check valve ball 610 abuts against and blocks the suction valve 400. When the liquid in the liquid outlet pipe is in a second pressure range, the check valve ball 610 releases the blockage of the suction valve 400, so that the liquid absorbed by the suction tube 540 can be sucked into the connector 700 (or the connector 700 can absorb the liquid via the suction tube 540).

[0079] More specifically, the check valve 600 may further include a check valve spring 620 that presses the check valve ball 610 toward the suction valve 400. The first pressure interval may be high pressure, so that even if the pressure at the second channel 720 is lower than the pressure at the first channel 710 based on the Bernoulli effect, the absolute value of the pressure at the second channel 720 is still high. Then, under the action of the check valve spring 620 and the pressure of the second channel 720, the check valve ball 610 abuts against and blocks the suction valve 400, preventing high-pressure liquid from entering the suction valve 400 and the liquid storage bottle 500 from the second channel 720.

[0080] The second pressure interval can be low pressure. Based on the Bernoulli effect, the second channel 720 generates negative pressure, the check valve ball 610 compresses the check valve spring 620, and the check valve ball 610 releases the blockage of the liquid suction valve 400. The liquid storage bottle 500, the liquid suction valve 400, the check valve 600, and the liquid outlet pipe 200 form a liquid path, and the liquid suction function is realized by negative pressure. The liquid sucked from the liquid storage bottle 500 is mixed with the water flow entering from the inlet valve 300, and then discharged through the liquid outlet pipe 200.

[0081] Therefore, in the case of high-pressure liquid discharge, the check valve 600 provided in the present application can prevent high-pressure liquid from entering the liquid suction valve 400 and the liquid storage bottle 500 to prevent backflow. In the case of low-pressure liquid discharge and the liquid suction valve 400 is unobstructed (described later), liquid can be normally sucked and foam can be sprayed.

[0082] The liquid in the liquid storage bottle 500 may be various liquids such as herbicides and foaming detergents.

[0083] It is understandable that some solutions will place the liquid storage bottle 500 at the nozzle of the cleaning machine (downstream of the liquid outlet pipe 200), which is heavier at the nozzle, with the center of gravity forward, making the water gun difficult to hold. The present application places the liquid storage bottle 500 at the handle of the cleaning machine water gun, with a reasonable center of gravity position, which is easy to hold and conforms to the principles of ergonomics.

[0084] See also Figure 3 , the liquid suction valve 400 may include a valve body 410 and a valve core 420. The valve body 410 includes a valve body inlet 411 and a valve body outlet 412. The valve core 420 is configured to be rotatable in the valve body 410, and a groove 421 is provided in the valve core 420. By rotating the valve core 420, the valve body inlet 411 and the valve body outlet 412 can be blocked, or the valve body inlet 411 and the valve body outlet 412 can be connected through the groove 421 (for example, Figure 3 The valve core 420 in the valve body is rotated 90° counterclockwise to adjust whether the suction valve 400 is unobstructed.

[0085] See also Figure 2 The handle of the washing machine water gun also includes an adjusting knob 800, which is configured to drive the valve core 420 to rotate. Exemplarily, the adjusting knob 800 is connected to the valve core 420 by gear transmission. Of course, the valve core 420 can also be driven to rotate by magnetic force, electric control, etc.

[0086] See also Figure 3 When it is not necessary to absorb liquid from the liquid storage bottle 500 (for example, to output pure water at low pressure), the adjusting knob 800 is rotated to block the valve body inlet 411 and the valve body outlet 412. When it is necessary to absorb liquid from the liquid storage bottle 500 (for example, to output foam), the adjusting knob is rotated to connect the valve body inlet 411 and the valve body outlet 412, and negative pressure is generated when the low-pressure water flows through the connector 700, and then the liquid in the liquid storage bottle 500 enters the liquid suction valve 400, the check valve 600, and the connector 700, and mixes with the water flow of the inlet valve 300, and is output to the outside through the liquid outlet pipe 200. Of course, when high-pressure output is performed, the check valve 600 will be blocked as mentioned above, and at this time, even if the liquid suction valve 400 is not blocked, it will not have much effect.

[0087] See also Figure 3 , the radial cross-sectional areas of the groove 421 of the valve core 420 at each position can be consistent. Figure 4 The liquid suction valve 400 can also be a flow regulating valve with adjustable opening size. The radial cross-sections of various positions of the groove 421 can be set inconsistently, so that the width of the channel between the valve body inlet 411 and the valve body outlet 412 can be adjusted by rotating the valve core 420, thereby adjusting the amount of liquid suction to avoid waste.

[0088] See also Figure 4, more specifically, the groove 421 may include a first position 4211, a second position 4212, and a third position 4213. The circumferential distance between the first position 4211 and the second position 4212 may be the same as the circumferential distance between the second position 4212 and the third position 4213. The volume of the groove 421 between the first position 4211 and the second position 4212 is A, and the volume of the groove 421 between the second position 4212 and the third position 4213 is B, and A>B. By rotating the valve core 420, the valve body inlet 411 and the valve body outlet 412 can be communicated through the groove 421 between the first position 4211 and the second position 4212, or through the groove 421 between the second position 4212 and the third position 4213. For example, when more liquid is to be drawn from the liquid storage bottle 500, the valve body inlet 411 and the valve body outlet 412 can be communicated through the groove 421 between the first position 4211 and the second position 4212. When it is desired to absorb less liquid from the liquid storage bottle 500 , the valve body inlet 411 and the valve body outlet 412 can be communicated through the groove 421 between the second position 4212 and the third position 4213 .

[0089] More specifically, the groove 421 between the first position 4211 and the second position 4212 can be connected to the valve body inlet 411 (or the valve body outlet 412) to absorb more liquid from the liquid storage bottle 500; or the groove 421 between the second position 4212 and the third position 4213 can be connected to the valve body inlet 411 (or the valve body outlet 412) to absorb less liquid from the liquid storage bottle 500.

[0090] See also Figure 2 The handle of the washing machine water gun may include a pressing portion 900 and a fulcrum 910, and the pressing portion 900 can rotate around the fulcrum 910. At this time, as shown by the arrow, when a person holds the handle and moves the right end of the pressing portion 900 upward, the left end of the pressing portion 900 will naturally move downward. Figure 3 , the inlet valve 300 includes a spring 310, a ball 320, a push rod 330, and a valve body channel 340. The spring 310 is connected to (e.g. pressed against) the ball 320 and presses the ball 320 against the valve body channel 340, one end of the push rod 330 is connected to (e.g. pressed against) the ball 320, and the other end can be connected to (e.g. pressed against) one end (left end) of the pressing portion 900. Here, optionally, a spring can be arranged between one end (left end) of the pressing portion 900 and the valve housing of the inlet valve 300, and the spring can be arranged around the push rod 330.

[0091] When a person manually presses the other end (right end) of the pressing part 900, one end (left end) of the pressing part 900 can drive the push rod 330 (downward) to press the ball 320 and the spring 310, thereby making the valve body inner channel 340 unblocked, and the water flow can pass smoothly, thus realizing the function of controlling the water flow through the pressing part 900. In addition, the structure of the inlet valve 300 can also avoid undesirable situations, such as the water flow already flowing when the pressing part 900 is not pressed.

[0092] See also Figure 1 , Figure 2 , the liquid storage bottle 500 is detachably mounted on the handle body. The cleaning machine water gun handle may further include a liquid storage bottle connection port 530. For example, the liquid storage bottle connection port 530 has an internal thread, the liquid storage bottle 500 has an external thread, and the liquid storage bottle 500 may be connected to the liquid storage bottle connection port 530 by threading. The cleaning machine water gun handle may be formed by splicing two half shells of substantially the same structure, and the liquid storage bottle connection port 530 may be located at the bottom of the cleaning machine water gun handle and connected to the two half shells at the same time.

[0093] Further, in one embodiment, see Figure 6 The cleaning machine water gun handle may include an infusion tube 510, one end of the infusion tube 510 is connected to the suction tube 540 (for example, the infusion tube 510 is connected to the suction tube 540 through a joint 550), and the other end of the infusion tube 510 is connected to the suction valve 400 (see Figure 2 The liquid pipette 540 is located in the liquid storage bottle 500 , and the liquid infusion tube 510 is located in the housing 100 .

[0094] A tube pressing plate 520 is provided in the housing 100, and the tube pressing plate 520 presses the infusion tube 510 against the housing 100, and the pressing position is closer to the liquid storage bottle connection port 530 than to the liquid suction valve 400. On the one hand, the tube pressing plate 520 can prevent the infusion tube 510 from moving, avoiding affecting the connection with the liquid suction valve 400 and the liquid suction tube 540; on the other hand, it can help control the shape of the infusion tube 510. Placing the infusion tube 510 in the housing 100 can also improve the overall appearance of the cleaning machine water gun handle, and also make it more convenient for users to operate. Of course, the aforementioned valves, pipes and other components can be located in the housing.

[0095] In another embodiment, the infusion tube 510 and the suction tube 540 may be integrally formed (not shown). Similarly, the infusion tube 510 may be partially pressed against the housing 100 by the pressing plate 520, and the pressing position is closer to the liquid storage bottle connection port 530 than to the suction valve 400.

[0096] See also Figure 5In another embodiment, the liquid storage bottle connection port 530 and the liquid storage bottle 500 may be arranged close to the liquid suction valve 400. In this embodiment, the aforementioned infusion tube 510 and the tube pressing plate 520 located in the housing 100 may not be provided, and one end of the liquid suction tube 540 may be directly inserted into the liquid storage bottle connection port 530 and the liquid storage bottle 500, and the other end of the liquid suction tube 540 is connected to the liquid suction valve 400. A C-type lock connected to the liquid suction valve 400 may also be provided on the liquid storage bottle connection port 530. The C-type lock may include a metal pin, and by clamping the two ends of the pin into the liquid suction valve 400, the liquid storage bottle connection port 530 can be rotated within a certain range.

[0097] The specifications of the cleaning machine water gun handle provided in this application can be able to withstand high pressure, for example, the working pressure range is 100~1000bar, and it can be used under high pressure conditions or low pressure conditions. Of course, the working pressure range can also be set to other values ​​to meet various types of cleaning needs.

[0098] The cleaning machine provided in the present application may include the aforementioned cleaning machine water gun handle. Furthermore, the cleaning machine may also include a gun rod, a nozzle, a main unit, etc. In one example, the cleaning machine may be a telescopic cleaning machine for roof cleaning. The gun rod is a telescopic gun rod, and a rotatable joint is also provided between the nozzle and the gun rod to facilitate adjustment of the rotation angle of the joint. The main unit is used to provide water flow, and the water flow is connected to the cleaning machine spray gun handle through a water inlet pipe. When cleaning, for example, a roof or other high positions, the length of the gun rod and the angle of the joint can be adjusted to clean certain dead corners.

[0099] The above is a preferred embodiment of the present application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
