[0048] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] like Figure 1-Figure 4 As shown, the present application provides a container for a spraying device, comprising a pot body 1 and a pot cover 2.

[0050] The pot cover 2 is provided with a protruding connecting tube 21, and the outer tube wall of the connecting tube 21 is provided with at least one connecting portion 22, and the connecting portion 22 includes two first ribs 221 arranged side by side, and a slot 223 is formed between the two first ribs 221, and the slot 223 extends along the outer circumference of the connecting tube 21;

[0051] The kettle cover 2 is arranged on the kettle body 1, and the slot is configured to form an insertion space.

[0052] Specifically, the connecting tube 21 on the pot cover 2 forms a corresponding connecting portion 22 of an integrated structure, and the connecting portion 22 is composed of two first ribs 221, and a slot is formed between the two first ribs 221 to meet the installation requirements. In this way, during use, the external component for fixing the pot cover is correspondingly formed with an inserting portion, so that the inserting portion is inserted between the two first ribs through the inserting portion, and then the inserting portion is clamped between the two first ribs 221 to complete the assembly.

[0053] Since the plug-in part is clamped between the two first ribs 221, during use, the shaking of the plug-in part will alternately apply external force to the two first ribs 221. The two first ribs 221 are used to withstand the impact force generated by the plug-in part during use, thereby reducing damage to the first ribs 221 and improving reliability.

[0054] Preferably, the connecting portion 22 further includes a second rib 222 , and the second rib 222 is connected between two of the first ribs 221 , and the first rib 221 and the second rib 222 form a sideways U-shaped structure.

[0055] Specifically, the connecting portion 22 of the integral structure formed on the connecting tube 21 of the pot cover 2 is composed of two first ribs 221 and one second rib 222, and the two first ribs 221 are connected by the second rib 222 so that the connecting portion 22 forms a sideways U-shaped structure. In this way, during use, after the two first ribs 221 arranged side by side are subjected to force, the force can be transmitted between the two first ribs 221 through the second rib 222 to improve the structural strength.

[0056] Since the two first ribs 221 are connected by the second rib 222, the force is transmitted to the other first rib 221 through the second rib 222, so that the two first ribs 221 can jointly bear the force generated by the plug-in part. In this way, fatigue damage caused by frequent stress on a single rib on the connecting pipe 21 can be effectively reduced.

[0057] In one embodiment, the connecting pipe 21 on the kettle cover 2 can be directly assembled to the spray gun 5 , or can be indirectly installed on the spray gun through the adapter 3 .

[0058] like Fig.14 As shown, the connecting tube 21 on the pot cover 2 can be directly assembled onto the spray gun 5, and the spray gun 5 has a plug-in port 51, and the plug-in port 51 is connected to the nozzle of the spray gun, and a fourth rib 52 is provided on one side of the plug-in port on the spray gun, and the connecting tube 21 is inserted into the plug-in port 51, and the fourth rib 52 is inserted into the slot. Specifically, the fourth rib 52 serves as a plug-in portion. During assembly, the connecting tube 21 is first inserted into the plug-in port 51, and then the pot cover 2 is rotated so that the fourth rib 52 is inserted between the two first ribs 221. Typically, the fourth rib 52 can be in a spiral wedge-shaped structure, so that it becomes tighter and tighter during insertion between the two first ribs 221, thereby improving the connection reliability. During use, when the painter holds the spray gun to spray, as the spray gun swings back and forth, the lid 2 will generate alternating opposite forces at the connection point with the fourth rib 52, so that the fourth rib 52 is alternately subjected to the pressure generated by the two first ribs 221.

[0059] like Figure 1As shown, the connecting tube 21 on the pot cover 2 can be indirectly installed on the spray gun through the adapter joint 3, and the inner wall of the adapter joint 3 is provided with a plug-in portion matching the connecting portion 22, and the plug-in portion is a third rib 31 formed on the inner wall of the adapter joint 3, and the third rib 31 extends along the inner circumference of the adapter joint 3; the adapter joint 3 is sleeved on the outside of the connecting tube 21, and the third rib 31 is inserted into the slot 223, and the end of the connecting tube 21 is interference fit with the adapter joint 3. Specifically, the third rib 31 serves as a plug-in portion. After the adapter joint 3 is assembled to the pot cover 2, the third rib 31 formed on the inner wall of the adapter joint 3 will be inserted into the slot 223, thereby realizing the assembly of the adapter joint 3 to the pot cover 2. During use, when the painter holds the spray gun to spray, the pot body 1 and the pot cover 2 are installed on the spray gun through the adapter joint 3. As the spray gun shakes back and forth, the pot cover 2 will generate alternating opposite forces on the connection part with the adapter joint 3, so that the third rib 31 is alternately subjected to the pressure generated by the two first ribs 221.

[0060] The following is a further description of the installation of the spraying equipment container on the spray gun through the adapter 3. The newly added structural design of the spraying equipment container is also applicable to direct installation on the spray gun, which will not be described in detail.

[0061] In one embodiment, the connecting pipe 21 may be provided with a plurality of connecting portions 22 as required, such as Figure 4 As shown, in order to improve the connection reliability, two connection parts 22 arranged back to back may be provided on the outer tube wall of the connecting tube 21 ; correspondingly, two third ribs 31 are provided in the adapter joint 3 .

[0062] In one embodiment, the opening of the slot 223 is in a trumpet-shaped structure, and the slot width of the slot 223 gradually decreases from the opening to the tail.

[0063] Specifically, in order to facilitate the smooth insertion of the third rib 31 into the slot 223, the opening of the slot 223 is a bell-mouth structure, so that during the process of inserting the third rib 31 into the slot 223, the bell-mouth structure can smoothly insert the third rib 31 into the slot 223. At the same time, the slot width of the slot 223 gradually decreases from the opening to the tail, so that after the third rib 31 is inserted into the slot 223, the third rib 31 can be smoothly inserted, and after the third rib 31 is assembled in place, the third rib 31 is tightly clamped between the two first ribs 221 to ensure a firm and reliable connection. Among them, the third rib 31 is interference fit with the slot 223.

[0064] In yet another embodiment, a locking rib 3223 is further provided on the outer surface of the adapter joint. The locking rib 3223 extends along the circumference of the adapter joint and is arranged obliquely relative to the center line of the adapter joint.

[0065] Specifically, the locking ribs 3223 configured on the adapter joint are arranged obliquely, so that they can cooperate with the threads on the spray gun to facilitate the assembly of the adapter joint to the spray gun.

[0066] In another embodiment, a plurality of annular grooves 24 arranged side by side are provided at the free end of the connecting pipe 21 , and a sealing ring 25 is formed between two adjacent annular grooves 24 , and the sealing ring 25 is in contact with the inner wall of the adapter joint 3 .

[0067] Specifically, since the pot cover 2 is made of plastic material, in order to achieve a better sealing effect after the connecting pipe 21 of the pot cover 2 is inserted into the adapter joint 3, a plurality of annular grooves 24 arranged side by side are formed on the connecting pipe 21, and sealing rings 25 are formed between the annular grooves 24. After the connecting pipe 21 is inserted into the adapter joint 3, the sealing ring 25 abuts against the inner wall of the adapter joint 3 and deforms to a certain extent into the annular grooves 24, thereby improving the sealing performance.

[0068] A connecting portion 22 is provided on the connecting tube 21 of the protective cover, and the two first ribs 221 in the connecting portion 22 are connected together through the second rib 222 to form a U-shaped structure, and a slot 223 is formed between the two first ribs 221 to meet the requirement that the adapter joint 3 is connected through the third rib 31. Since the third rib 31 is inserted between the two first ribs 221, it can be ensured that the third rib 31 is firmly clamped by the two first ribs 221, thereby meeting the requirement that the adapter joint is firmly and reliably assembled on the pot cover 2. During use, the pot body 1 can alternately apply supporting force to the two first ribs 221 through the third rib 31 due to shaking. At the same time, the two first ribs 221 are connected together through the second rib 222, so that the structural strength of the connecting portion 22 itself is increased, and the structural strength of the connecting tube 21 is also increased, and the damage of the connecting tube 21 is reduced, so as to improve the connection reliability between the pot cover 2 and the conversion joint, so as to improve the reliability of the use of the paint pot.

[0069] In some embodiments, the kettle body 1 may be a single-body structure, or may be a split-body structure.

[0070] For the kettle body 1 of a single body structure, a receiving space for storing fluid is formed between the kettle body 1 and the kettle cover 2. The kettle body 1 is a single body structure, and the kettle body 1 and the kettle cover 2 are sealed together to form a receiving space for storing fluid therebetween.

[0071] For the kettle body 1 with a split structure, Figure 2 and Figure 4 As shown, the kettle body 1 includes an outer cup 11 and an inner cup 12, the edge of the cup mouth of the inner cup 12 is provided with an outer flange 121, and the outer flange 121 overlaps the cup mouth of the outer cup 11; the kettle cover 2 is provided with an annular extrusion portion 26, the kettle cover 2 is arranged on the outer cup 11, the annular extrusion portion 26 is inserted into the cup mouth of the inner cup 12, and the outer flange 121 is clamped between the inner cup 12 and the outer cup 11.

[0072] Specifically, the outer cup 11 has strong rigidity to meet the requirement of not being deformed during use; and the inner cup 12 has strong flexibility to meet the requirement that the inner cup 12 can deform itself after the fluid flows out during use.

[0073] The outer cup 11 is provided with a hollow structure 111 to ensure that during use, negative pressure is not formed in the outer cup 11 to affect the smooth outflow of the fluid in the inner cup 12 .

[0074] In addition, in order to fix the pot cover 2 on the outer cup 11, the container for spraying equipment also includes a tightening ring 4, which is provided with a first thread, and the outer wall of the outer cup 11 is provided with a second thread matching the first thread; the tightening sleeve is fixed to the outer cup 11 by connecting the first thread and the second thread, and the pot cover 2 is clamped between the outer cup 11 and the tightening ring 4.

[0075] Specifically, after the pot cover 2 is placed on the outer cup 11, the pot cover 2 is pressed and fixed on the outer cup 11 by tightening the collar 4, and the tightening collar 4 and the outer cup 11 can be connected together by conventional fixed connection methods such as threads.

[0076] In the second embodiment, the present application further provides a container for a spraying device, which comprises a kettle body 1, a kettle cover 2 and an adapter joint 3, wherein the kettle body 1 in the present embodiment adopts a split structure, that is, the kettle body 1 comprises an outer cup 11 and an inner cup 12.

[0077] like Figure 5-Figure 7 As shown, for the pot lid 2, in order to reduce the manufacturing cost, the connection between the pot lid 2 and the outer cup 11 no longer relies on an additional annular connecting piece, but a first locking portion 110 of an integral structure is provided on the outer cup 11, and correspondingly, an integrally formed second locking portion 20 is provided on the edge of the pot lid 2.

[0078] Specifically, a hollow structure 111 is provided on the outer cup 11, and an outer flange 121 is provided on the edge of the cup mouth of the inner cup 12, and the outer flange 121 overlaps the cup mouth of the outer cup 11; an annular extrusion portion 26 is provided on the pot cover 2, and the pot cover 2 is arranged on the outer cup 11, and the annular extrusion portion 26 is inserted into the cup mouth of the inner cup 12; wherein, after the first locking portion 110 and the second locking portion 20 are connected, the outer flange 121 is clamped between the inner cup 12 and the outer cup 11, and the first locking portion 110 and the second locking portion 20 are tightly attached together by relying on the elasticity generated by the outer flange 121.

[0079] Specifically, the edge of the pot cover 2 is provided with a second locking portion 20 of an integral structure. When in use, the second locking portion 20 cooperates with the first locking portion 110 on the outer cup 11 to fix the pot cover 2 on the outer cup 11, thereby saving parts and reducing manufacturing costs.

[0080] Among them, since parts are saved, in order to ensure the reliability of the connection between the pot cover 2 and the outer cup 11, the outer flange 121 of the inner cup 12 sandwiched between the outer cup 11 and the pot cover 2 is squeezed by the pot cover 2 and the outer cup 11 to react with the pot cover 2 by the elastic force generated, so that the first locking part 110 and the second locking part 20 are tightly attached together. In this way, while reducing parts to reduce costs, it is ensured that the pot cover 2 and the outer cup 11 are connected tightly together by the elastic force generated by the outer flange 121.

[0081] The second locking portion 20 of an integral structure is formed on the edge of the pot cover 2 to cooperate with the first locking portion 110 on the outer cup 11 to complete the assembly of the pot cover 2 onto the outer cup 11, and no additional tightening ring 4 is required to fix the pot cover 2 on the outer cup 11, so as to reduce the manufacturing cost; at the same time, since the outer flange 121 of the inner cup 12 can be clamped between the cup mouth of the outer cup 11 and the pot cover 2, the outer flange 121 of the inner cup 12 is plastically deformed to generate an elastic force on the pot cover 2 away from the outer cup 11, so that the first locking portion 110 and the second locking portion 20 are tightly attached together, so as to ensure a firm and reliable connection between the pot cover 2 and the outer cup 11.

[0082] In one embodiment, if Figure 6 As shown, the cup mouth of the outer cup 11 is provided with an outer folding edge 112, the edge of the outer folding edge 112 is provided with a folding edge 113, the inner surface of the folding edge 113 is provided with a protruding first locking portion 110, and a locking groove is formed between the first locking portion 110 and the outer folding edge 112; the edge of the pot cover 2 is provided with a plurality of outwardly protruding second locking portions 20, and the second locking portions 20 are located on the outer side of the annular extrusion portion 26;

[0083] After the kettle cover 2 is arranged on the kettle body 1 , the second locking portion 20 is inserted into the locking groove and the second locking portion 20 is tightly attached to the first locking portion 110 due to the elasticity generated by the outer flange 121 .

[0084] Specifically, the outer cup 11 is provided with an outer folding edge 112 extending outward, and the first locking portion 110 is arranged through the folding edge 113 provided on the outer folding edge 112, so that the outer folding edge 121 of the inner cup 12 can overlap the surface of the outer folding edge 112. The edge of the pot cover 2 is provided with a second locking portion 20, so that the second locking portion 20 extends into the bottom of the first locking portion 110 and is inserted into the locking groove. Moreover, under the elastic force of the outer folding edge 121 of the inner cup 12, the second locking portion 20 is tightly attached to the first locking portion 110.

[0085] The first locking portion 110 may be a first protruding locking strip formed on the inner surface of the folded edge 113, and correspondingly, the second locking portion 20 may be a second protruding locking strip formed on the edge of the lid 2. The first locking strip is arranged obliquely relative to the outer folded edge 112.

[0086] In addition, in order to facilitate the user to rotate the pot cover 2, a plurality of raised friction ribs 27 may be further provided on the surface of the pot cover 2.

[0087] Among them, for the outer folded edge 112 on the outer cup 11, as Figure 6 As shown, the outer fold 112 is annular in structure, and the outer fold 112 surrounds the periphery of the cup opening of the outer cup 11. Fig.13 As shown, a plurality of outer folded edges 112 are arranged at intervals on the cup opening of the outer cup 11 .

[0088] In another embodiment, if Figure 8-Figure 11 As shown, the outer wall of the outer cup 11 is provided with the first locking portion 110, and the edge of the pot cover 2 is also provided with a plurality of folded extension portions 28, the inner surface of the folded extension portion 28 is provided with the second locking portion 20, and the folded extension portion 28 is arranged on the outside of the annular extrusion portion 26, and the folded extension portion 28 extends along the outer wall of the outer cup 11 toward the bottom of the outer cup 11; wherein, after the pot cover 2 is arranged on the pot body 1, the second locking portion 20 is connected to the first locking portion 110 and relies on the elasticity generated by the outer flange 121 to make the second locking portion 20 tightly attached to the first locking portion 110.

[0089] Specifically, the first locking portion 110 is located on the outer wall surface of the outer cup 11, and the edge of the pot cover 2 is provided with a folded extension portion 28 to be arranged on the outer circumference of the outer cup 11, and the folded extension portion 28 is provided with a second locking portion 20, so that the pot cover 2 is directly fixed on the outer cup 11 through the cooperation of the second locking portion 20 and the first locking portion 110. The first locking portion 110 and the second locking portion 20 may be expressed as threads.

[0090] In one embodiment, in order to ensure that the pot cover 2 and the outer cup 11 are accurately assembled in place, a strip opening 29 is provided on the pot cover 2 , and the strip opening 29 is arranged on the inner side of the second locking portion 20 .

[0091] Specifically, the strip opening 29 passes through the pot lid 2 and is located on the inner side of the second locking portion 20. The strip opening 29 allows the operator to observe the connection status of the first locking portion 110 and the second locking portion 20 through the strip opening 29, thereby facilitating the operator to intuitively check whether the pot lid 2 and the outer cup 11 are assembled in place.

[0092] The arrangement of the strip-shaped openings 29 can also reduce the amount of material used in one embodiment, thereby more effectively reducing the manufacturing cost.

[0093] In order to facilitate observation by operators, after the kettle cover 2 is arranged on the kettle body 1 , the strip-shaped opening 29 and the first locking portion 110 are arranged opposite to each other.

[0094] A connecting portion 22 is provided on the connecting tube 21 of the protective cover, and the two first ribs 221 in the connecting portion 22 are connected together through the second rib 222 to form a U-shaped structure, and a slot 223 is formed between the two first ribs 221 to meet the requirement that the adapter joint 3 is connected through the third rib 31. Since the third rib 31 is inserted between the two first ribs 221, it can be ensured that the third rib 31 is firmly clamped by the two first ribs 221, thereby meeting the requirement that the adapter joint is firmly and reliably assembled on the pot cover 2. During use, the pot body 1 can alternately apply supporting force to the two first ribs 221 through the third rib 31 due to shaking. At the same time, the two first ribs 221 are connected together through the second rib 222, so that the structural strength of the connecting portion 22 itself is increased, and the structural strength of the connecting tube 21 is also increased, and the damage of the connecting tube 21 is reduced, so as to improve the connection reliability between the pot cover 2 and the conversion joint, so as to improve the reliability of the use of the paint pot.

[0095] In some embodiments, since the inner cup 12 is sealed by the pot cover 2, during use, as the fluid in the inner cup 12 decreases, the inner cup 12 will form an internal negative pressure and cause the inner cup 12 to deform, thereby causing the fluid in the inner cup 12 to be unable to be completely discharged. Fig.12As shown, a switchable air valve 122 is also provided on the inner cup 12 .

[0096] Specifically, the air valve 122 is opened and closed according to the use state. During the spraying process, the air valve 122 is in an open state. At this time, the inner cup 12 is inverted, so that the air valve 122 is located at the top. When the air valve 122 is opened, the fluid in the inner cup 12 flows out through the connecting tube 121, and the outside air can enter the inner cup 12 through the air valve 122, thereby reducing the deformation of the inner cup 12, so that the fluid in the inner cup 12 can flow out more completely.

[0097] In addition, for the container for spraying equipment in the second embodiment, the connecting portion 22 arranged on the connecting pipe 21 can also be represented by an inclined rib with a limiting rib arranged at the end of the inclined rib, that is, Figure 7 The connecting portion 22 is shown in FIG.

[0098] Embodiment 3: Based on the above-mentioned embodiments 1 and 2, the present application further provides a container for spraying equipment, wherein the structural design of the connecting pipe 21 and the adapter joint on the lid 2 adopts the structural form of embodiment 1. As for the kettle body 1, it adopts a split structure, and the structural design of the kettle body 1 and the lid 2 adopts the structural form of embodiment 2.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
