[0003] The existing airbrush structure can be found in the Chinese utility model patent with the announcement number CN203389788U, which discloses a beauty airbrush, which includes a pen body with a front handle and a rear handle screwed together, the interior of the pen body is set as a cavity, the outer wall of the front handle is provided with a beauty liquid storage cavity connected to the cavity, the front handle is provided with a central hole for the beauty liquid to be discharged on the other side of the screw-on end, a nozzle is provided at the central hole, the nozzle and the central hole are connected by threads, the beauty airbrush is provided with a spray needle, the spray needle passes through the nozzle and the central hole, the spray needle cooperates with the nozzle port to form a sealing surface, the front handle is provided with an air valve at the other end relative to the nozzle, the air outlet of the air valve is connected to the central hole; a button is provided on the pen body, the button Located just above the air valve, the end of the button is connected to the air valve core, and the air valve switch is controlled by radially pressing the button. A spray needle clamping device is provided in the cavity, and the spray needle and the spray needle clamping device are fixedly connected. The button controls the axial movement of the spray needle clamping device by axial toggling, thereby controlling the movement of the spray needle, thereby adjusting the spray amount of the beauty liquid at the nozzle port; when in use, the beauty liquid is put into the beauty liquid holding cavity, the air valve is opened by pressing the button, compressed air is introduced into the pen body cavity, and then the axial movement button is used to control the axial movement of the spray needle, so that the compressed air squeezes the beauty liquid out of the nozzle; the airbrush uses the same button to open the air valve and the spray needle at the same time, which simplifies the operation of the beauty airbrush.

[0004] Another example is the Chinese utility model patent with the announcement number CN208411279U, which discloses an air pump airbrush that integrates the air pump airbrush with a battery module, solving the problem that the air pump airbrush requires power support and is inconvenient to move and operate. A control circuit board is arranged on the lower side of the operation button of the existing airbrush, and a control key is arranged on the surface of the control circuit board. The operation button is fixedly connected to the control circuit board through the control key, thereby controlling the power supply of the battery module.

[0005] However, in the above technical solution, the airbrush and the air pump for providing compressed air are separately arranged, that is, the air pump introduces compressed air into the pen body cavity of the airbrush through an air pipe. Therefore, when the user operates the airbrush, firstly, the existing airbrush button is arranged on the upper side of the pen body, which is not convenient for human hand to hold and operate; secondly, the air pump air pipe interferes with the connection of the airbrush, which causes many inconveniences to the user's mobile operation. Summary of the invention

[0006] In view of the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a handheld integrated airbrush, which integrates an air pump and an airbrush in an ergonomically designed grip handle, and controls the operation of the air pump and the airbrush simultaneously through a trigger-type operating button, making it more convenient to hold and operate.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A handheld integrated airbrush comprises a shell with a gripping handle, an upper accommodating chamber and a lower accommodating chamber are formed in the shell, the upper accommodating chamber of the shell is provided with an airbrush assembly, and the lower accommodating chamber of the shell is provided with an air pump assembly, the air pump assembly is used to introduce compressed air into the airbrush assembly; it also comprises an operation button, the operation button is reciprocatingly arranged at the gripping handle portion of the shell through an elastic member, the operation button is subjected to the elastic force of the elastic member during the pressing stroke; the operation button comprises a second control part, when the operation button is pressed, the second control part controls the size of the nozzle opening of the airbrush assembly to be opened as the pressing displacement of the operation button changes during the pressing stroke of the operation button; when the operation button is released, the operation button is reset under the elastic force of the elastic member, and the second control part controls the nozzle opening of the airbrush assembly to be closed.

The air pump assembly is integrally fixedly mounted in the lower accommodating cavity of the housing.

[0023] Furthermore, the shell is formed by buckling together two left and right half shells.

[0024] After adopting the above technical solution, the advantages of the present invention compared with the prior art are:

[0025] In the prior art, firstly, the airbrush does not have a dedicated grip handle, and the operating button is located above the pen body. Therefore, when the hand holds the airbrush and presses the operating button, the arm's control over the direction of the nozzle will be greatly affected. At the same time, the accuracy of the airbrush nozzle opening is difficult to control, which is very inconvenient to use; secondly, the airbrush and the air pump are separately arranged, and the airbrush and the air pump are connected by an air pipe. The air pipe is exposed to the outside and will hinder the movement of the airbrush to a certain extent, affecting the operation; thirdly, the operating button of the airbrush needs to be moved in two directions to be controlled, that is, pressing downward is used to control the air valve or air pump and axial movement is used to control the size of the nozzle opening. The control accuracy of this operating button control method is low. Compared with the prior art, the present invention includes a shell with an ergonomically designed grip handle to enhance the grip feel, which is beneficial to the overall control of the airbrush, and the air pump assembly and the airbrush assembly are integrated in the shell. The movement of the airbrush and the change of the nozzle direction are not affected by the gripping method and the pipeline, so it is more convenient to operate; in addition, the present invention arranges the operation button in the position of the grip handle, similar to the trigger structure, so that the operation button can be very conveniently controlled while holding the airbrush, and the operation mode of the operation button is a pressing operation in a single direction to control the air pump assembly and the airbrush assembly at the same time. Therefore, compared with the prior art, the present invention is more convenient to hold and operate.

[0026] The present invention also makes further innovative designs for the shell, airbrush assembly, operating button and air pump assembly, etc. The beneficial technical effects thereof will be further described in the specific implementation manner below and will not be repeated here.

[0036] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0037] See also Figure 1 and Figure 2 A handheld integrated airbrush comprises a shell 10 having a grip handle 100. The shell 10 is preferably a hard injection molded part. The shell 10 is formed by buckling two left and right half shells for easy assembly.

[0038] See also Figure 3 and Figure 4An upper accommodating chamber 11 and a lower accommodating chamber 12 are formed in the shell 10. The upper accommodating chamber 11 of the shell 10 is provided with a spray pen assembly 20, and the lower accommodating chamber 12 of the shell 10 is provided with an air pump assembly 30. The air pump assembly 30 is used to supply compressed air to the spray pen assembly 20.

[0039] See also Figure 5 The airbrush assembly 20 includes a pen body 21 with a cavity inside, and a feeding assembly connected to the cavity is provided on the upper side of the pen body 21. Specifically, the feeding assembly is a copper cap 22 with a feeding channel. The pen body 21 is a hollow cylinder made of metal. A circular hole is provided on the upper side of the pen body 21. The copper cap 22 is placed in the circular hole and is welded and fixed. The feeding channel of the copper cap 22 is connected to the cavity of the pen body 21. The copper cap 22 is used to connect a material cup filled with paint.

[0040] A nozzle assembly 23 is connected to the front end of the pen body 21, and the nozzle assembly 23 is provided with a central spray hole connected to the cavity. A spring sleeve 24 is connected to the rear end of the pen body 21. A clamping spring (not shown) and a spray needle clamping shaft 25 inserted through the clamping spring are sleeved in the spring sleeve 24. A locking nut 26 is connected to the rear end of the spring sleeve 24. The two ends of the clamping spring are respectively abutted against the spray needle clamping shaft 25 and the locking nut 26. A spray needle 27 extending into the cavity and cooperating with the central spray hole is clamped on the spray needle clamping shaft 25.

[0041] During assembly, the nozzle assembly 23 is first connected to the front end of the pen body 21, the spring sleeve 24 is screwed to the rear end of the pen body 21, the spray needle 27 is inserted into the spray needle clamping shaft 25, and then the spray needle clamping shaft 25 and the clamping spring are sequentially inserted into the spring sleeve 24, and finally the locking nut 26 is screwed to the spring sleeve 24. The assembled nozzle assembly 23 is then fixedly installed in the upper accommodating cavity 11 of the housing 10.

[0042] See also Figure 4 The air pump assembly 30 includes an air compressor pump body 31 and a motor 32 for driving the air compressor pump body 31. The air compressor pump body 31 is arranged at the upper end of the motor 32 and is drivingly connected to the output shaft of the motor 32. The air pump assembly 30 is fixedly mounted in the lower accommodating chamber 12 of the shell 10 as a whole.

[0043] The working process of the airbrush in this embodiment is similar to that of the airbrush in the background art, and the working principle of the output of compressed air by the air pump assembly 30 is common technical knowledge in the field, so it will not be repeated. It should be noted here that although the structure and principle of the airbrush assembly in this embodiment are similar to those of the airbrush in the background art, the airbrush assembly 20 and the air pump assembly 30 of the present invention are not limited thereto, and the conventional structures of other airbrush assemblies and air pump assemblies in the field can be equivalently replaced within the scope of the present invention.

[0044] Furthermore, the airbrush assembly 20 is provided with an air inlet pipe joint 28, one end of which extends into the airbrush assembly 20 and corresponds to the central spray hole, and the air pump assembly 30 is provided with an exhaust pipe joint 33, and the air inlet pipe joint 28 and the exhaust pipe joint 33 are connected through an air pipe (not shown), and the air pipe is arranged in the upper accommodating chamber 11 of the housing 10. Specifically, the air inlet pipe joint 28 is arranged beside the pen body 21, so that the air pipe can be as close to the inner wall of the housing 10 as possible, and will not affect the pressing operation of the operation button 50.

[0045] See also Figure 6 The handheld integrated airbrush of this embodiment further includes a switch component 40, which is used to control the start and stop operation of the air pump assembly 30. Specifically, the switch component 40 includes a momentary switch 41, which is a conventional switch part, and includes a switch contact 42, and the switch control can be realized by touching the contact 42. The momentary switch 41 is fixedly mounted on the inner wall of the upper accommodating cavity 11 of the housing 10 through a circuit board 43, and is electrically connected to the air pump assembly 30.

[0046] See also Figure 3 and Figure 4 The handheld integrated airbrush of this embodiment further comprises an operation button 50, which is reciprocatably arranged at the gripping handle 100 of the housing 10 through an elastic member 60. Specifically, the elastic member 60 is a spring, and the portion of the operation button 50 exposed outside the housing 10 is a pressing portion, which is adapted to the finger portion of a human body. The operation button 50 is provided with a guide column on the inner side of the housing 10, and the spring is sleeved on the guide column, and the two ends of the spring are respectively against the inner wall of the housing 10 and the inner side of the operation button 50. The housing 10 is provided with a mounting hole 13 adapted to the pressing portion, and the operation button 50 reciprocates on the housing 10 under the limited cooperation between the pressing portion and the mounting hole 13. The operation button 50 is subjected to the elastic force of the elastic member 60 during the pressing stroke, and the elastic force of the elastic member 60 enables the operation button 50 to maintain the movement tendency of extending outward from the housing 10, and is also used for the reset movement when the operation button 50 is released.

[0047] See also Figure 6 and Figure 7The operation button 50 includes a first control unit 51 and a second control unit 52. When the operation button 50 is pressed, the first control unit 51 controls the switch component 40 to remain in an open state during the pressing stroke of the operation button 50, thereby controlling the air pump assembly 30 to start operation, and the second control unit 52 controls the nozzle opening of the airbrush assembly 20 to change with the pressing displacement of the operation button 50 during the pressing stroke of the operation button 50; when the operation button 50 is released, the operation button 50 is reset under the elastic force of the elastic member 60, the first control unit 51 controls the switch component 40 to close, thereby controlling the air pump assembly 30 to stop operation, and the second control unit 52 controls the nozzle opening of the airbrush assembly 20 to close.

[0048] The first control part 51 is a block that matches the contact 42 of the inching switch 41. When the inching switch 41 is installed in the upper accommodating cavity 11 of the housing 10, its contact 42 faces the moving direction of the operation button 50. In the initial state, the block is in a position just in contact with the contact 42. Once the operation button 50 is pressed, the block will keep touching the contact 42 of the inching switch 41 as the operation button 50 moves, so that the inching switch 41 always remains in an open state during the pressing stroke of the operation button 50.

[0049] The second control part 52 is a shift block extending into the airbrush assembly 20. The shift block is provided with a through slot 521 for the spray needle 27 of the airbrush assembly 20 to pass through. The through slot 521 plays a role in avoiding the spray needle 27 from passing through. Figure 5 The rear end of the pen body 21 is provided with a slide groove 211 for the shift block to extend into, corresponding to the position of the spray needle clamp shaft 25. When the shift block is extended into the slide groove 211, it abuts against the spray needle clamp shaft 25. As the operation button 50 is pressed and reciprocated, the shift block also slides back and forth in the slide groove 211, and drives the spray needle clamp shaft 25 to move axially back and forth in the pen body 21, thereby adjusting the opening size between the spray needle 27 and the nozzle assembly 23 to achieve the adjustment of the paint spraying amount.

[0050] See also Figure 4 and Figure 7As a preferred embodiment, the operation button 50 further includes a third control unit 53, and the housing 10 is further provided with a self-locking rebounder 70 cooperating with the third control unit 53. When the operation button 50 is pressed, when the third control unit 53 drives the self-locking rebounder 70 to be located at its self-locking position, the operation button 50 is limited and fixed at the pressed position; when the operation button 50 is pressed again, when the third control unit 53 drives the self-locking rebounder 70 to be located at its rebounding position, the operation button 50 is released from the limited fixation and reset under the elastic force of the elastic member 60. Among them, the structure and principle of the self-locking rebounder 70 are common technical knowledge in the relevant field, and as a structural member for realizing the self-locking rebound function, it can be purchased arbitrarily on the market, so it will not be described in detail.

[0051] Further, the third control part 53 is a slot fixedly connected to the movable end 71 of the self-locking rebounder 70. After the slot is fixedly connected to the movable end 71 of the self-locking rebounder 70, the movable end 71 of the self-locking rebounder 70 can be moved along with the movement of the operation button 50, and when the self-locking rebounder 70 is in the self-locking position, the operation button 50 is also limited and locked in this position. Usually, the self-locking position of the self-locking rebounder 70 is close to the maximum contraction of its movable end 71, that is, when the operation button 50 is limited and locked, the pressing stroke of the operation button 50 is close to the maximum stroke of its pressing. At this time, the shifting block shifts the needle clamping shaft 25 to the position where the opening between the needle 27 and the nozzle assembly 23 is the largest, that is, the airbrush does not need to press the operation button 50 at this time, and it can also maintain the working state of the maximum ejection amount and continue to operate.

[0052] See also Figure 1 and Figure 2 As a preferred embodiment, the rear end of the housing 10 is provided with a detachably connected rear cover 101, and the rear cover 101 corresponds to the rear end of the spray pen assembly 20. When the rear cover 101 is removed, an opening 14 is formed at the rear end of the housing 10, and the locking nut 26 at the rear end of the pen body 21 can be unscrewed from the opening 14, and then the clamping spring, the spray needle clamping shaft 25 and the spray needle 27 can be taken out in sequence, which is convenient for cleaning or replacement of the assembly parts.

[0053] The rear cover 101 is made of soft rubber material, and buckles 1011 are provided on both sides of the rear cover 101. A plurality of positioning buckles 1012 are provided on the buckles 1011. Positioning holes 1013 matching the positioning buckles 1012 are provided on both sides of the housing 10. The buckles 1011 are detachably fixedly connected to the rear end of the housing 10 through the engagement of the positioning buckles 1012 with the positioning holes 1013. Of course, the rear cover 101 can also be made of hard material, and its detachable connection with the housing 10 can also be equivalent replacement methods such as plug-in, card connection and screw connection. In this embodiment, the buckle 1011 made of soft rubber material is selected, which has the functions of anti-collision and convenient disassembly and assembly, and also has a beautiful decorative effect.

[0054] Similarly, a detachably connected front cover 102 may also be provided at the front end of the housing 10, and the front cover 102 is sleeved on the nozzle portion of the airbrush assembly 20. After the front cover 102 is removed, an opening is formed at the front end of the housing 101, and the nozzle assembly 23 can be taken out from the opening for cleaning or replacement.

[0055] Furthermore, a detachably connected top cover 103 is provided at the upper end of the housing 10, and the top cover 103 is provided with a feed hole 1031 adapted to the feed port of the airbrush assembly 20. Specifically, the feed hole 1031 on the top cover 103 matches the outer diameter of the copper cap 22, and in order to prevent the paint from flowing into the housing 10 along the gap between the feed hole 1031 and the copper cap 22, an annular groove for installing a sealing ring 1032 is also provided on the outer periphery of the copper cap 22, and the gap between the feed hole 1031 and the copper cap 22 is sealed by the sealing ring 1032.

[0056] Furthermore, a detachably connected bottom cover 104 is provided at the lower end of the shell 10 . The bottom cover 104 is made of a soft rubber material and is used to seal the lower end of the shell 10 to prevent the shell 10 from being damaged by collision.

[0057] See also Figure 3 and Figure 4As a preferred embodiment, an annular groove 15 is provided in the shell 10, and the annular groove 15 is located between the upper accommodating chamber 11 and the lower accommodating chamber 12. The upper sleeve of the air pump assembly 30 is provided with a sealing member 311, and the sealing member 311 is tightly clamped in the annular groove 15. The seal 311 on the upper part of the air pump assembly 30 seals and separates the upper accommodating chamber 11 and the lower accommodating chamber 12 in the shell 10. The upper accommodating chamber 11 is used to install the spray pen assembly 20 and the switch button 50 and other execution control components. Specifically, the first control part 51, the second control part 52 and the third control part 53 of the operation button 50 are integrally formed and located in the upper accommodating chamber 11. The moment switch 41, the self-locking rebounder 70 and the elastic member 60 are all located in the upper accommodating chamber 11, and these components have lower waterproof requirements; the lower accommodating chamber 12 is used to install the air pump assembly 30, including the motor 32, the circuit control board 90 and the power supply assembly 80 and other live components, and these components have relatively high waterproof requirements.

[0058] Furthermore, a power supply assembly 80 and a circuit control board 90 are also provided in the lower accommodating chamber 12. The circuit control board 90 is provided with a power button 91 exposed on the surface of the housing 10.
