[0040] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0041] It should be noted that when an element is referred to as being "fixed on" or "set on" another component, it can be directly on the other component or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0043] Please refer to Figure 1 to Figure 3 The present invention provides a feed control assembly 5, which is installed on a feed channel 4, and includes: a feed port 51 installed on the top of the feed channel 4, a hollow bottom plate 52 fixedly installed at the bottom of the feed port 51, a plurality of control screws 53 circumferentially distributed on the edge of the hollow bottom plate 52, a plurality of blades 54 installed in the hollow part of the hollow bottom plate 52, fixing screws 55 installed on the plurality of blades 54, and a sliding connector 56.

[0044] A plurality of blades 54 are distributed in a circle to seal the hollow part of the hollow bottom plate 52. One end of the sliding connector 56 is fixedly installed with the blade 54, and the other end is installed one-to-one with the control screw 53. By rotating the feed port 51 to rotate the hollow bottom plate 52, the control screw 53 is driven to push the sliding connector 56, thereby controlling the opening and closing of the blade 54 and controlling the entry of the spray material.

[0045] In this embodiment, a feed control component 5 capable of controlling the feed speed is arranged on the feed channel 4. The feed port 51 is rotated so that the control screw 53 pushes the sliding connector 56 to control the opening and closing of the blade 54, thereby controlling the feed speed, proportion and flow rate of the spray. The arrangement of the feed control component 5 makes the feeding method more flexible and convenient, and enhances the controllability and practicality of the device.

[0046] In this embodiment, the speed and proportion of the spraying material entering is controlled by rotating the feed port 51. Specifically, when feeding is required, the feed port 51 is rotated clockwise, so that the hollow bottom plate 52 fixedly mounted with the feed port 51 starts to rotate clockwise, and the control screw 53 on the hollow bottom plate 52 positively pushes the sliding connection 56 to rotate, and cooperates with the fixing screw 55 to fix one corner of the blade 54, so that the blade 54 installed at the other end of the sliding connection 56 rotates outward, and at this time, a plurality of blades 54 slide outward at the same time to the open state, and the spraying material can enter.

[0047] When it is necessary to stop feeding, the two feed ports 51 are rotated counterclockwise to rotate the hollow base 52 counterclockwise, and the control screw 53 on the hollow base 52 pushes the sliding connector 56 in the opposite direction to rotate, driving the blades 54 fixedly installed at the other end of the sliding connector 56 to rotate inward. At this time, several blades 54 rotate inward at the same time to a closed state, and feeding is stopped.

[0048] It is further explained that the outward rotation angle of the blades 54 can be controlled by rotating the feed port 51, thereby controlling the speed of the spray entering.

[0049] like Figure 1 to Figure 5As shown, the present invention also provides a solid-liquid dual-spray self-mixing spray gun with controllable feed speed using the above-mentioned feed adjustment component, including a front shell 1, a mixing cavity 8 arranged inside the front shell 1 for mixing spray materials, an air chamber 9 arranged at the front end of the mixing cavity 8, a ventilation cavity 10 arranged at the front end of the air chamber 9, and a spray needle 14 penetrating the mixing cavity 8, the air chamber 9 and the ventilation cavity 10; the air chamber 9 is connected to the air intake mechanism 6 through the air intake channel 13, a plurality of stirring blades 12 are fixedly installed on the spray needle 14, and a plurality of ventilation holes 11 connected to the ventilation cavity 10 are arranged on the side wall of the air chamber 9.

[0050] The air intake mechanism 6 is controlled to allow air flow to enter the air chamber 9 through the air intake channel 13. The air flow enters the ventilation cavity 10 through the ventilation hole 11, driving the stirring blades 12 in the ventilation cavity 10 to rotate, and the spray needle 14 rotates accordingly, causing the stirring blades 12 inside the mixing cavity 8 to rotate. The rotation of the stirring blades 12 mixes the spray material in the mixing cavity 8.

[0051] In this embodiment, a mixing cavity 8, a ventilation cavity 10 and an air chamber 9 are arranged inside the front shell 1, so that after the airflow enters the air chamber 9, it flows into the ventilation cavity 10 through the ventilation hole 11, blows the stirring blade 12 in the ventilation cavity 10, and the spray needle 14 rotates accordingly, driving the stirring blade 12 located in the mixing cavity 8 fixedly installed with the spray needle 14 to stir and mix the spray material in the mixing cavity 8. This structure limits the direction of airflow by setting the air chamber 9, so that the mixed material will not flow back and block the air inlet channel 13, and the stirring blade 12 is driven by the airflow to continuously rotate and stir so that the spray material is fully mixed. The structure is simple and easy to operate, and the spray material is efficiently stirred and mixed inside the spray pen. The waste of spray material when the spray material is mixed and poured externally is avoided, and the spraying operation can be completed conveniently and efficiently.

[0052] In this embodiment, the air intake mechanism 6 is controlled so that the airflow enters the air chamber 9 through the air intake channel 13 and enters the ventilation cavity 10 through the ventilation hole 11 connected to the ventilation cavity 10. At this time, the airflow blows the stirring blade 12 in the ventilation cavity 10 to rotate and drives the spray needle 14 to rotate, thereby rotating the stirring blade 12 in the mixing cavity 8. The stirring blade 12 stirs the spray material in the mixing cavity 8 so that it is fully mixed to form a mixture.

[0053] It is further explained that, by providing the mixing cavity 8, the air chamber 9 and the ventilation cavity 10, and cooperating with the stirring blades 12 to stir and mix the spray material in the mixing cavity 8, the spray material is completely mixed, thereby ensuring the spraying quality.

[0054] It is further explained that the air chamber 9 is provided to limit the flow direction of the airflow, so that the mixed material will not flow back and block the air inlet channel 13. The structure is simple and easy to operate and the mixing efficiency is improved.

[0055] It is further explained that the air intake mechanism 6 can be controlled to adjust the flow rate of the air flow entering the air chamber 9, thereby adjusting the rotation speed of the stirring blade 12, and further controlling the mixing speed of the mixed material in the mixing cavity 8.

[0056] like Figure 1 to Figure 5 As shown, the solid-liquid dual-spray self-mixing spray brush with controllable feeding speed also includes a conical rear shell 2 installed at the rear end of the front shell 1, a nozzle 3 installed at the front end of the front shell 1, a spray control mechanism 7 installed inside the conical rear shell 2, and a feed channel 4 installed on the upper part of the front shell 1; the front shell 1, the conical rear shell 2 and the nozzle 3 are provided with a spray needle 14 passing through them, the air chamber 9 is provided with a sealing channel 91 for the spray needle 14 to pass through, and the feed channel 4 is provided with a feed control component 5 for controlling the feeding.

[0057] The spray control mechanism 7 is controlled to move the spray needle 14 backward, and the air intake mechanism 6 is cooperated to allow air flow to enter the air chamber 9 through the air intake channel 13, so that the spray material in the mixing cavity 8 is sprayed out from the nozzle 3 through the sealing channel 91.

[0058] In this embodiment, the air intake mechanism 6 is controlled to make the air flow enter the air chamber 9 through the air intake channel 13, and then flow into the ventilation cavity 10. The solid material and the liquid material are controlled to enter the mixing cavity 8 through the feed channel 4 for mixing by controlling the feed control assembly 5. After the mixing is completed, the spray control mechanism 7 is controlled to make the spray needle 14 move backward, and the spray brush is tilted to make the mixed material flow into the ventilation cavity 10 through the sealing channel 91, and then sprayed from the nozzle 3 along with the flow of the air flow. The structure is simple and convenient, and the spraying effect and quality are guaranteed while saving costs.

[0059] In this embodiment, the air intake mechanism 6 is first controlled to allow the gas to enter the air chamber 9 through the intake channel, and then the feed control component 5 is controlled to allow the spray material to enter the mixing chamber 8 from the feed channel 4. At this time, the stirring blades 12 in the mixing chamber 8 begin to rotate due to the influence of the airflow to automatically stir and mix the spray material. Then, the spray control mechanism 7 is controlled to make the spray needle 14 move backward, and after the airbrush is tilted, the mixed material in the mixing chamber 8 flows into the ventilation chamber 10 through the sealing channel 91, and the mixed material is driven to be sprayed out from the nozzle 3 by the flow of airflow.

[0060] like Figure 1 As shown, the feed channel 4 is divided into a solid feed channel 4 and a liquid feed channel 4 .

[0061] In this embodiment, the double feed channels 4 can be provided to allow solid and liquid materials to simultaneously enter the mixing chamber 8 for mixing, thereby avoiding waste of spray materials during external mixing and pouring, and completing the spraying operation conveniently and efficiently.

[0062] It is further explained that the number of the feed channels 4 can be adjusted according to the situation, and for the spray material mixed in the mixing chamber 8, double liquid material, double solid material or solid-liquid mixture can also be selected according to the situation.

[0063] like Figure 1 , Figure 2 and Figure 4 As shown, the air intake mechanism 6 includes: an air pump installed at the end of the air intake channel 13 and a regulating component 61 installed on the air intake channel 13 for controlling the inlet and outlet of the air flow; when the air pump is started, the air flow enters the air chamber 9 through the air intake channel 13.

[0064] In this embodiment, the air pump is controlled to allow the air flow to flow into the air chamber 9 through the air inlet channel 13, and the flow rate of the air flow and the like are adjusted by the adjustment component 61 installed on the air inlet channel 13. The setting of the adjustment component 61 facilitates the control of the air flow inflow, thereby enhancing the flexibility and practicality of the airbrush.

[0065] It is further explained that the regulating component 61 includes: a control unit 611 for controlling the air flow rate and a display screen 612 for displaying timing.

[0066] It is further explained that the conditions for starting and stopping the spraying are programmed on the control unit 611, and then the control unit 611 is connected to the valve of the air intake channel 13, and the control unit 611 is used to control the opening or closing of the valve, thereby controlling the air intake time of the air intake channel 13, so as to achieve the purpose of controlling the spraying time, and the spraying area is controlled by controlling the spraying time. This structure is equivalent to programming a delay program on the control unit 611, which can realize automatic control of the spraying operation time, and then control the spraying area, so that the operator can arrange the spraying operation more reasonably, and the spraying time can be displayed on the display screen 612, so that the operator can observe and adjust it.

[0067] It is further explained that the delay program on the control unit 611 needs to be calibrated and checked regularly to ensure the accuracy of the spraying area. The control unit 611 is preferably a microcontroller.

[0068] like Figure 1-2 As shown, the spray control mechanism 7 includes: a mounting sleeve 71 mounted on the spray needle 14, a sliding sleeve 72 arranged with the mounting sleeve 71 and the sliding sleeve 72, a fixing sleeve 73 fixedly mounted on the outside of the sliding sleeve 72, a stopper 76 mounted on the spray needle 14 and a baffle 77 passing through the wall of the conical rear shell 2 and abutting against the stopper 76; a spring 74 mounted on the spray needle 14 is arranged between the rear end of the mounting sleeve 71 and the rear end of the sliding sleeve 72, and a fixing seat 75 is installed at the tail end of the spray needle 14.

[0069] During spraying, the baffle plate 77 is first pulled out, and the fixing seat 75 is pulled to move the spray needle 14 backward, so that the fixing sleeve 73 is abutted against the conical rear shell 2, driving the mounting sleeve 71 to move backward and compress the spring 74 with the rear end of the sliding sleeve 72, so that the mixed material is sprayed out from the nozzle 3, and the baffle plate 77 is blocked at the front end of the block 76 to enable the nozzle 3 to continue to spray the spray material; when returning to the center, the spring 74 rebounds, driving the mounting sleeve 71 and the spray needle 14 to move forward to end the spraying.

[0070] In this embodiment, when spraying is required, the baffle 77 is first pulled out, and the fixing seat 75 is pulled to move the spray needle 14 backward, and the mounting sleeve 71 is driven to move backward, and the fixing sleeve 73 and the inner wall of the conical rear shell 2 are abutted against each other, so that the rear ends of the mounting sleeve 71 and the sliding sleeve 72 that move backward squeeze the spring 74. The spring 74 is compressed and contracts, and the baffle 77 is blocked in front of the block 76, so that the nozzle 3 can continue to spray.

[0071] When spraying needs to be stopped, the baffle 77 is pulled out and the spring 74 automatically rebounds and stretches to reset, driving the mounting sleeve 71 to move forward, so that the spray needle 14 fixedly mounted on the mounting sleeve 71 moves forward to reset, and the spray pen stops spraying.

[0072] It is further explained that the setting of the baffle 76 and the baffle 77 realizes the continuous and convenient spraying operation of the device, and the setting of the spring 74 realizes the automatic rebound of the device after the spraying is completed. The structure can complete the spraying operation simply, conveniently and efficiently.

[0073] like Figure 5 As shown, the nozzle 3 includes a first conical section 31 installed at the front end of the front shell 1, a second conical section 32 installed at the front end of the first conical section 31, and a nozzle 33 installed at the front end of the second conical section 32; a spray cap 34 is installed inside the nozzle 33, and a spray hole 35 for the spray needle 14 to pass through is arranged at the center of the spray cap 34, a channel 36 suitable for the spray needle 14 to pass through is arranged in the second conical section 32, and a discharge gap 37 for the spray material to pass through is arranged between the channel and the spray needle 14.

[0074] During spraying, the spray needle 14 moves backward and the spray material is sprayed out from the spray hole 35 ; when spraying is finished, the spray needle 14 moves forward to block the spray hole 35 .

[0075] In this embodiment, during the spraying operation, the fixing seat 75 is pulled to move the spray needle 14 backward to the circular hole away from the center of the spray cap 34, and the spray gun is tilted to allow the mixture in the mixing chamber 8 to flow into the ventilation chamber 10 through the sealing channel 91, and driven by the airflow in the air chamber 9, the mixture passes through the channel 36 in the first conical section 31 and the second conical section 32, and is finally sprayed out from the spray hole 35 inside the spray cap 34.

[0076] It is further explained that the setting of the discharge gap 37 makes the spraying of the mixed material smoother.

[0077] like Figure 5 As shown, an ultrasonic vibration piece 38 is installed in the second conical section 32 for fully mixing the solid material and the liquid material.

[0078] In this embodiment, the mixed material in the mixing chamber 8 is driven into the nozzle 3 by the airflow, and the mixed material is atomized by the ultrasonic oscillation sheet 38 installed between the second conical section 32 and the nozzle 33, and then sprayed out through the spray hole 35 in the middle of the nozzle 33.

[0079] It is further explained that the installation of the ultrasonic vibration plate 38 vibrates and atomizes the mixed material, making the solid material insoluble in the liquid material become finer and more uniform, which not only prevents the mixed material from clogging the nozzle 33, but also ensures the quality of spraying.

[0080] like Figure 1 to Figure 5 As shown, the present invention also provides a spraying method of a solid-liquid dual-spray self-mixing spray pen with controllable feeding speed, comprising the following steps:

[0081] S1. Control the air intake mechanism 6, the air flow enters the air chamber 9 through the air intake passage 13;

[0082] S2. The airflow flows from the air chamber 9 into the ventilation cavity 10 through the ventilation hole 11.

[0083] S3. The airflow drives the stirring blade 12 in the ventilation cavity 10 to rotate, and the spray needle 14 rotates accordingly, driving the stirring blade 12 in the mixing cavity 8 to rotate, and mixing and stirring the spray material in the mixing cavity 8.

[0084] The spraying method using the above-mentioned solid-liquid dual-spray self-mixing spray pen with controllable feed rate is as follows:

[0085] After starting the air intake mechanism 6, the air flow enters the air chamber 9 through the air intake channel 13, and flows into the ventilation cavity 10 through the ventilation hole 11 between the air chamber 9 and the ventilation cavity 10, blowing the stirring blade 12 in the ventilation cavity 10 to rotate, and the spray needle 14 fixedly mounted on the stirring blade 12 rotates accordingly, causing the stirring blade 12 fixedly mounted on the spray needle 14 and located in the mixing cavity 8 to rotate. At this time, the stirring blade 12 mixes and stirs the spray material in the mixing cavity 8.

[0086] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
