[0002] Leisure furniture can be classified into seat categories, table and desk categories, storage and decoration categories, etc. according to product forms. During the production process of leisure furniture, spraying equipment is usually required to spray paint on the skeleton to achieve the protective effect on the furniture.

[0003] In the prior art, a Chinese patent discloses a spraying and filtering system for furniture (Publication No.: CN213557938U), and its main structure includes a spray pipe. One end of the spray pipe is provided with a spray head, and one side of the spray head is provided with a nozzle. The bottom of the outer surface of the spray pipe is communicated with a discharge pipe. A fixed bin is fixedly connected behind the spray pipe. A filter plate is fixedly connected inside the spray pipe. A cleaning mechanism is arranged on the spray pipe; the cleaning mechanism includes a driving motor, the output end of the driving motor is fixedly connected with a rotating shaft, and the outer surface of the rotating shaft is respectively fixedly connected with a first support rod, a second support rod and a third support rod. One end of the first support rod is fixedly connected with a first cleaning brush, one end of the second support rod is fixedly connected with a second cleaning brush, and one end of the third support rod is fixedly connected with a third cleaning brush.

[0004] In actual use, the above patent generates power through the driving motor, so that the first cleaning brush, the second cleaning brush and the third cleaning brush clean the filter plate, making the surface of the filter plate clean and facilitating filtration. However, there are still corresponding drawbacks in actual use: during the production and long-term storage of paint, undissolved resin, pigment agglomerates or dander will form soft block impurities. When the above technical solution uses the driving motor to make the first cleaning brush, the second cleaning brush and the third cleaning brush move circumferentially to clean the soft block impurities on the filter plate, under the interaction between the movement of the cleaning brush and the filter holes of the filter plate, the soft block impurities are easily broken and embedded in the filter holes of the filter plate to cause blockage. When the paint liquid flows and sprays, the broken impurities blocking the filter holes are easily sprayed onto the surface of the furniture skeleton, resulting in poor cleaning effect, easily affecting the uniformity of the spraying thickness and the spraying quality, and reducing the spraying effect and efficiency on the furniture skeleton.

Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the cooperative design of structures such as a manual spray gun, a filtering mechanism, and a liquid storage tank, when the manual spray gun extracts paint liquid from the liquid storage tank, under the elastic force of the first spring compression rod, the sliding shell is pushed to move leftward. When the sliding shell moves leftward, it squeezes the paint liquid between the inner cavities of the connecting cylinder and the mounting cylinder. Under the pressure, the paint liquid can drive the vibration block to reciprocate left and right through the driving mechanism to produce a vibration effect, which can cause the paint liquid in the connecting cylinder and the sliding shell to oscillate. Through the oscillation effect, the soft block impurities can be separated from the filter plate. As the sliding shell moves, it drives the mounting shell to approach the filter plate, and the filtered paint liquid in the sliding shell can be squeezed, so that the filtered paint liquid passes through the filter plate from left to right and enters the connecting cylinder, which can perform backwashing on the filter plate. At the same time, the unfiltered paint liquid and the cleaned and fallen impurities flow back into the liquid storage tank through the reflux collection mechanism, which is convenient for automatically cleaning the filter plate after each spraying. Through liquid oscillation and backwashing, the soft blocks can be effectively separated from the filter plate, and the cleaning effect is good. When the soft block impurities are cleaned, they are not easily broken and embedded in the filter holes of the filter plate to cause blockage, improving the uniformity and quality of the spraying thickness, enhancing the spraying effect and efficiency on the furniture skeleton, and solving the problems in the prior art that under the interaction of the movement of the cleaning brush and the filter holes of the filter plate, the soft block impurities are easily broken and embedded in the filter holes of the filter plate to cause blockage, and when the paint liquid flows and sprays, the broken impurities blocking the filter holes are easily sprayed onto the surface of the furniture skeleton, the cleaning effect is poor, which easily affects the uniformity and quality of the spraying thickness, and reduces the spraying effect and efficiency on the furniture skeleton.

[0016] 2. Through the cooperative design of structures such as a vibration block, a mounting shell, and a pressure prompting mechanism, when the paint liquid passes through the liquid infusion hole, the paint liquid enters the tee pipe, and the paint liquid can push the sealing plug to move. The movement of the sealing plug drives the resistance ring to move through the connecting rod. When the resistance ring moves on the resistance block, the resistance detection sensor can detect the change in the resistance value and send the detected value to the display control screen for display, which is convenient for the operator to adjust the force of manually extruding the paint liquid according to the change in the resistance value and control the pressure when the paint liquid is extruded and sprayed, and can further improve the uniformity and stability of the spraying, solving the problems in the prior art that when the operator manually extrudes the paint liquid for spraying, it is not convenient to accurately adjust the force of manually extruding the paint liquid, which easily causes uneven spraying of the paint liquid and poor stability.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 10 shown, the present invention provides a spraying device for a leisure furniture skeleton, including a manual spray gun 1, a filtering mechanism 2 provided at the liquid outlet end of the manual spray gun 1. The manual spray gun 1 is a prior art, and its structure and principle will not be elaborated here. An atomizing nozzle 3 provided at the liquid outlet end of the filtering mechanism 2 and a liquid storage tank 4 communicated with the manual spray gun 1 through a one-way valve; The filtering mechanism 2 includes an installation cylinder 21 arranged at the liquid outlet end of the manual spray gun 1, a connecting cylinder 22 fixedly installed in the right cavity of the installation cylinder 21 through a connecting rod, a filter plate 23 fixed to the left cavity of the connecting cylinder 22, a sliding shell 24 slidably sleeved on the left outer surface of the connecting cylinder 22, an installation shell 25 slidably moving left and right in the cavity of the sliding shell 24, a vibration block 26 slidably moving left and right in the right opening of the installation shell 25, a driving mechanism 5 arranged on the installation shell 25 and on the right side of the sliding shell 24, a pressure prompting mechanism 6 arranged on the vibration block 26, a reflux collecting mechanism 7 arranged at the bottom of the connecting cylinder 22, and a confluence shell 27 horizontally fixed to the left cavity of the installation cylinder 21; Among them, a group of liquid infusion holes 28 are opened on the outer surface of the connecting cylinder 22, a limiting groove 29 is opened on the left cavity of the sliding shell 24, a group of docking holes 210 are circumferentially and equidistantly opened on the left outer surface of the installation shell 25, a first hose 211 for connecting the docking holes 210 with the cavity of the confluence shell 27 is fixedly installed on the left side wall of the installation shell 25, liquid outlet holes and liquid inlet holes are respectively opened at the left and right ends of the installation cylinder 21, the cavity of the liquid outlet hole is communicated with the cavity of the confluence shell 27, the cavity of the liquid outlet hole is communicated with the cavity of the atomizing nozzle 3, the cavity of the liquid inlet hole is communicated with the liquid outlet port of the manual spray gun 1, a group of first spring compression rods 10 connected to the left side of the sliding shell 24 are circumferentially and equidistantly fixed to the left cavity of the installation cylinder 21, and a group of second spring compression rods 11 connected to the right side of the installation shell 25 are circumferentially and equidistantly fixed to the right cavity of the sliding shell 24.

[0021] During use, in the initial state, the sliding shell 24 is located on the right side of the cavity of the installation cylinder 21. When the operator holds the manual spray gun 1 and squeezes out the paint liquid, the paint liquid enters through the liquid inlet hole at the right end of the installation cylinder 21, and the liquid pressure pushes the sliding shell 24 to move to the left side of the cavity of the installation cylinder 21; When the manual paint gun 1 draws out the paint liquid from the liquid storage tank 4, under the elastic force of the first spring compression rod 10, the sliding shell 24 is pushed to move leftward. When the sliding shell 24 moves leftward, it seals and closes the liquid infusion hole 28. At the same time, when the sliding shell 24 moves leftward, it squeezes the paint liquid between the connecting cylinder 22 and the inner cavity of the mounting cylinder 21. Under the action of pressure, the paint liquid can drive the vibration block 26 to reciprocate left and right to generate a vibration effect, which can make the paint liquid in the connecting cylinder 22 and the sliding shell 24 oscillate. Through the oscillation effect, the soft block impurities can be separated from the filter plate 23. As the sliding shell 24 continues to move rightward, under the elastic force of the second spring compression rod 11, the mounting shell 25 is embedded into the limiting groove 29, and the inner cavity of the limiting groove 29 seals and closes the docking hole 210. As the sliding shell 24 moves and drives the mounting shell 25 to approach the filter plate 23, the filtered paint liquid in the sliding shell 24 can be squeezed, so that the filtered paint liquid passes through the filter plate 23 from left to right and enters the connecting cylinder 22, which can perform backwashing on the filter plate 23. At the same time, the unfiltered paint liquid and the cleaned and shed impurities flow back into the liquid storage tank 4 through the reflux collection mechanism 7, which is convenient for automatically cleaning the filter plate 23 after each spraying. Through liquid oscillation and backwashing, the soft block can be effectively separated from the filter plate 23, and the cleaning effect is good. When the soft block impurities are cleaned, they are not easily broken and embedded into the filter holes of the filter plate to cause blockage, which improves the uniformity and quality of the spraying thickness, and improves the spraying effect and efficiency of the furniture skeleton.

[0022] It should be noted that when the manual paint gun 1 extrudes the paint liquid, the paint liquid enters through the liquid inlet hole at the right end of the mounting cylinder 21. The liquid pressure pushes the sliding shell 24 to move leftward into the inner cavity of the mounting cylinder 21. The sliding shell 24 drives the mounting shell 25 to move leftward. After the left side wall of the mounting shell 25 contacts the right end of the confluence shell 27, as the sliding shell 24 continues to move leftward, the docking hole 210 can be separated from the inner cavity wall of the limiting groove 29 and enter the inner cavity of the sliding shell 24. At the same time, the paint liquid enters the connecting cylinder 22 through the liquid infusion hole 28. The paint liquid filtered by the filter plate 23 flows into the inner cavity of the sliding shell 24. Then the paint liquid passes through the liquid infusion hole 28, through the first hose 211, enters the confluence shell 27, and is sprayed through the atomizing nozzle 3 onto the furniture skeleton. When the paint liquid passes through the liquid infusion hole 28, under the action of the pressure of the paint liquid, it can drive the pressure prompting mechanism 6 to operate. The pressure prompting mechanism 6 can detect and display the pressure when the operator manually extrudes the paint liquid for spraying. By observing the detected and displayed pressure value, the operator can easily adjust the force of manually extruding the paint liquid, which can further improve the uniformity and stability of the spraying, and solves the problem in the prior art that when the operator manually extrudes the paint liquid for spraying, it is not easy to accurately adjust the force of manually extruding the paint liquid, which easily causes uneven spraying of the paint liquid and poor stability.

[0023] Such as Figure 3 、 Figure 5 、 Figure 6 、Figure 7 , Figure 8 and Figure 9 As shown in Figure 7 , Figure 8 and Figure 9 , the driving mechanism 5 includes a sealing block 51 that moves left and right on the right side wall of the connecting cylinder 22, a group of support rods 52 circumferentially fixed to the outer surface of the right side of the sealing block 51, a group of connecting channels 53 circumferentially and equidistantly opened in the right side cavity of the sliding housing 24, a communicating pipe 54 sliding in the connecting channel 53, an annular impeller 55 arranged in the inner cavity of the mounting housing 25, and a transmission mechanism 8 arranged on the right side of the annular impeller 55 for driving the vibration block 26 to move. Among them, the right end of the communicating pipe 54 penetrates through the support rod 52 and is fixedly connected to the right side cavity of the mounting cylinder 21. A delivery hole 56 adapted to the support rod 52 is opened on the outer surface of the right side of the communicating pipe 54. An installation groove is circumferentially opened in the inner cavity of the mounting housing 25. The left and right side walls of the annular impeller 55 are respectively movably connected to the left and right sides of the inner cavity of the installation groove through bearings. A second hose 57 for communicating the inner cavity of the installation groove with the inner cavity of the connecting channel 53 is fixedly installed on the outer surface of the mounting housing 25. The shape of the sealing block 51 is adapted to the shape of the liquid inlet hole. An annular inner rail is fixedly installed on the right side wall of the annular impeller 55. An annular outer rail is sleeved on the outer surface of the right side of the annular inner rail. The inner cavity of the annular outer rail is communicated with the inner cavity of the annular inner rail. A first liquid discharge hole communicating with the inner cavity of the annular impeller 55 is opened in the inner cavity of the annular inner rail. A group of water delivery pipes 9 are circumferentially and equidistantly fixedly installed on the right side wall of the vibration block 26. The inner cavity of the water delivery pipe 9 is communicated with the inner cavity of the annular outer rail. The right end of the water delivery pipe 9 penetrates to the right side of the filter plate 23. The annular impeller 55 is composed of an annular block and a group of blades. An annular groove is circumferentially opened on the outer ring of the annular block. A group of blades are circumferentially and equidistantly inclined and fixed in the inner cavity of the annular groove. A sliding groove is opened on the right side wall of the connecting cylinder 22. The outer surface of the sealing block 51 is slidably connected to the inner cavity of the sliding groove. A spring seat is fixedly installed on the left side of the inner cavity of the sliding groove. The output shaft end of the spring seat is fixedly connected to the left side wall of the sealing block 51.

[0024] During use, when the manual paint gun 1 draws out the paint liquid from the liquid storage tank 4, the spring seat drives the sealing block 51 to move to the right to close the liquid inlet hole at the right end of the installation cylinder 21. The sealing block 51 moves to the right and drives the support rod 52 to move to the right, enabling the delivery hole 56 to be exposed. Under the elastic force of the first spring compression rod 10, the sliding shell 24 is pushed to move to the left. At the same time, when the sliding shell 24 moves to the left, the paint liquid between the connecting cylinder 22 and the inner cavity of the installation cylinder 21 is squeezed. After being squeezed, the paint liquid passes through the delivery hole 56, through the connecting pipe 54 and the connecting channel 53, and enters the installation groove through the second hose 57. The impact generated by the squeezed paint liquid entering the installation groove can drive the annular impeller 55 to rotate. When the annular impeller 55 rotates, it can drive the vibration block 26 to move left and right reciprocally through the transmission mechanism 8, generating an oscillation effect on the paint liquid in the sliding shell 24 and the connecting cylinder 22, and cleaning the soft block impurities attached to the filter plate 23 through the oscillation effect. At the same time, the paint liquid entering the installation groove can flow into the connecting cylinder 22 through the first drain hole, the annular inner rail, the annular outer rail, and the water delivery pipe 9, and the impurities cleaned and shed can flow back into the liquid storage tank 4 through the reflux collection mechanism 7.

[0025] As Figure 5 and Figure 6 shown, the transmission mechanism 8 includes a group of arc-shaped protrusions 81 circumferentially and equidistantly fixed on the right side wall of the annular impeller 55, rollers 82 circumferentially and equidistantly rotatably installed on the vibration block 26 and cooperating with the arc-shaped protrusions 81, and a group of third spring compression rods 83 circumferentially and equidistantly arranged on the right side wall of the vibration block 26; Among them, the left and right ends of the third spring compression rod 83 are respectively connected to the right side wall of the vibration block 26 and the right side of the inner cavity of the installation shell 25.

[0026] During use, when the impact generated by the squeezed paint liquid entering the installation groove drives the annular impeller 55 to rotate, the annular impeller 55 rotates to drive the arc-shaped protrusions 81 to rotate circumferentially. Under the interaction between the circumferential rotation of the arc-shaped protrusions 81 and the rollers 82, the vibration block 26 can be intermittently pushed to move to the left. At the same time, in cooperation with the elastic force of the third spring compression rod 83 driving the vibration block 26 to move to the right, the vibration block 26 can move left and right reciprocally to generate an oscillation effect.

[0027] As Figure 2 and Figure 8 shown, the reflux collection mechanism 7 includes a first touch sensor 71 and a second touch sensor 72 fixedly installed between the left side of the inner cavity of the chute and the left side wall of the sealing block 51, a touch ring 73 arranged between the first touch sensor 71 and the second touch sensor 72, a sewage discharge pipe 74 vertically and fixedly installed on the bottom surface of the connecting cylinder 22, an aggregate screening cylinder 75 threadedly and detachably installed at the bottom end of the sewage discharge pipe 74, and an electromagnetic valve 76 arranged on the sewage discharge pipe 74; Among them, the bottom of the sewage discharge pipe 74 penetrates into the inner cavity of the liquid storage tank 4. A through hole matching the sewage discharge pipe 74 is opened on the bottom surface of the inner cavity of the sliding shell 24. A connecting sleeve is fixedly installed on the left side wall of the sealing block 51. The inner ring of the touch ring 73 is fixedly connected to the outer surface of the connecting sleeve. The touch ring 73 is movably connected to the first touch sensor 71 and the second touch sensor 72 respectively. When the touch ring 73 contacts the first touch sensor 71 and the second touch sensor 72 respectively, it can control the opening and closing of the solenoid valve 76.

[0028] During use, when the manual spray gun 1 extracts the paint liquid from the liquid storage tank 4, the spring seat drives the sealing block 51 to move to the right to close the liquid inlet hole at the right end of the installation cylinder 21. The sealing block 51 drives the touch ring 73 to move and contact the second touch sensor 72. The second touch sensor 72 controls the opening of the solenoid valve 76, facilitating the unfiltered paint liquid and the cleaned and fallen impurities to flow back into the liquid storage tank 4 through the sewage discharge pipe 74, and the aggregate sieve tube 75 can collect the cleaned and fallen impurities; when the manual spray gun 1 extrudes the paint liquid, the paint liquid enters through the liquid inlet hole at the right end of the installation cylinder 21, pushing the sealing block 51 to move to the left. The sealing block 51 drives the touch ring 73 to move and contact the first touch sensor 71. The first touch sensor 71 can control the closing of the solenoid valve 76.

A display control screen 67 is fixedly installed on the top surface of the installation cylinder 21; Among them, one end of the connecting rod 65 is hinged to one end of the sealing plug 62. A group of rectangular cavities are circumferentially and equidistantly opened on the left side of the installation shell 25. The inner cavity of the liquid infusion hole 28 is communicated with the inner cavity of the rectangular cavity. The inner cavity of the first hose 211 is communicated with the inner cavity of the rectangular cavity. The resistance block 63 and the resistance ring 64 are respectively electrically connected to the resistance detection sensor 66, and the resistance detection sensor 66 is electrically connected to the display control screen 67.

[0030] During use, when the paint liquid passes through the infusion hole 28, the paint liquid enters the tee 61. The paint liquid can push the sealing plug 62 to move. The movement of the sealing plug 62 drives the resistance ring 64 to move through the connecting rod 65. When the resistance ring 64 moves on the resistance block 63, the resistance detection sensor 66 can detect the change in the resistance value and send the detected value to the display control screen 67 for display, facilitating the operator to adjust the force of manually extruding the paint liquid according to the change in the resistance value, controlling the pressure when the paint liquid is extruded and sprayed, and further improving the uniformity and stability of spraying.

[0031] The working principle and usage process of the present invention: In use, initially, the sliding shell 24 is located on the right side of the inner cavity of the installation cylinder 21 in the initial state. When the operator holds the manual paint gun 1 and squeezes out the paint liquid, the paint liquid enters through the liquid inlet hole at the right end of the installation cylinder 21, pushing the sealing block 51 to move leftward. The sealing block 51 moves the touch ring 73 to contact the first touch sensor 71. The first touch sensor 71 controls the solenoid valve 76 to close. The liquid pressure pushes the sliding shell 24 to move to the left side of the inner cavity of the installation cylinder 21. The sliding shell 24 drives the installation shell 25 to move leftward. After the left side wall of the installation shell 25 contacts the right end of the confluence shell 27, as the sliding shell 24 continues to move leftward, the docking hole 210 can be separated from the inner cavity wall of the limiting groove 29 and enter the inner cavity of the sliding shell 24. At the same time, the paint liquid enters the connecting cylinder 22 through the liquid infusion hole 28. The paint liquid filtered by the filter plate 23 flows into the inner cavity of the sliding shell 24. Then the paint liquid passes through the liquid infusion hole 28, through the first hose 211, enters the confluence shell 27, and is sprayed onto the furniture skeleton through the atomizing nozzle 3. When the paint liquid passes through the liquid infusion hole 28, the paint liquid enters the tee 61. The paint liquid can push the sealing plug 62 to move. The movement of the sealing plug 62 drives the resistance ring 64 to move through the connecting rod 65. When the resistance ring 64 moves on the resistance block 63, the resistance detection sensor 66 can detect the change in the resistance value and send the detected value to the display control screen 67 for display, facilitating the operator to adjust the intensity of manually squeezing out the paint liquid according to the change in the resistance value, control the pressure when the paint liquid is squeezed out and sprayed, and improve the uniformity and stability of spraying;When the manual spray gun 1 withdraws the paint liquid from the liquid storage tank 4 after spraying, the spring seat drives the sealing block 51 to move rightward to close the liquid inlet hole at the right end of the installation cylinder 21. The sealing block 51 drives the touch ring 73 to move and contact the second touch sensor 72. The second touch sensor 72 controls the solenoid valve 76 to open. The sealing block 51 moves rightward to drive the support rod 52 to move rightward, enabling the delivery hole 56 to be exposed. Under the elastic force of the first spring compression rod 10, the sliding shell 24 is pushed to move leftward. At the same time, when the sliding shell 24 moves leftward, the paint liquid between the connecting cylinder 22 and the inner cavity of the installation cylinder 21 is squeezed. After being squeezed, the paint liquid passes through the delivery hole 56, through the connecting pipe 54 and the connecting channel 53, and enters the installation groove through the second hose 57. The impact generated by the squeezed paint liquid entering the installation groove can drive the annular impeller 55 to rotate. The rotation of the annular impeller 55 drives the arc-shaped convex block 81 to rotate circumferentially. Under the interaction between the circumferential rotation of the arc-shaped convex block 81 and the roller 82, the vibration block 26 can be intermittently pushed to move leftward. At the same time, in cooperation with the elastic force of the third spring compression rod 83 driving the vibration block 26 to move rightward, the vibration block 26 can move left and right reciprocally to oscillate the paint liquid in the sliding shell 24 and the connecting cylinder 22. As the sliding shell 24 moves to drive the installation shell 25 to approach the filter plate 23, the filtered paint liquid in the sliding shell 24 can be squeezed, so that the filtered paint liquid passes through the filter plate 23 from left to right and enters the connecting cylinder 22, which can backwash the filter plate 23. At the same time, the paint liquid entering the installation groove can flow into the connecting cylinder 22 through the first drain hole, the annular inner rail, the annular outer rail and the water delivery pipe 9, facilitating the unfiltered paint liquid and the cleaned and fallen impurities to flow back to the liquid storage tank 4 through the sewage discharge pipe 74, and the collected sieve cylinder 75 can collect the cleaned and fallen impurities.
