Description

Technical Field

[0001] This invention relates to the field of spray gun technology, and in particular, to a spray gun and its storage structure. Background Technology

[0002] Existing lever-type spray guns (such as the Chinese utility model patent with announcement number CN201161220Y) have a core structure including a spray bar with a spray hood connected to the front end of the spray bar, which enables the atomization and spraying of liquid.

[0003] The above-mentioned types of spray guns require several loose accessories for complete assembly and normal use, including adapters, filters, springs, spray blades, O-rings, and rubber gaskets. In the current factory delivery model, manufacturers usually pack these loose accessories into a separate accessory bag and then distribute them to users along with the spray gun body.

[0004] In practical usage scenarios, the timing of use for different accessories varies significantly: The filter and adapter are "essential accessories". Users need to take them out of the accessory bag and install them at the water inlet of the spray gun before connecting them to the water pipe to ensure that the spray gun can receive water normally. (2) Springs, spray blades, O-rings and rubber pads are considered "subsequent maintenance / adjustment accessories". They should only be removed from the accessory bag and replaced when the corresponding accessories inside the spray gun are worn or fail, or when the spray size needs to be adjusted or the sealing performance needs to be repaired according to the usage requirements.

[0005] Because all accessories are stored in a single accessory bag, and their usage scenarios are diverse (installation and subsequent maintenance), users need to repeatedly open and retrieve the accessory bag for different scenarios throughout the entire lifecycle of the spray gun. This not only reduces operational convenience but also makes it easy for accessories to be lost due to their scattered locations and repeated retrieval. If critical accessories are lost, the spray gun will be unable to be assembled properly or maintained in a timely manner. Summary of the Invention

[0006] In view of this, the first objective of the present invention is to provide a storage structure that makes reasonable use of the internal space of the spray nozzle, effectively reduces the probability of loss of accessories, and is highly convenient to use.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: A storage structure includes a spray nozzle and a spray bar. The spray nozzle has a receiving space inside; It also includes a mounting cover and a mounting base. The mounting base has a mounting position for fixing loose accessories. The mounting cover is installed on the nozzle of the spray hood, and the mounting base is located in the accommodating space between the spray hood and the mounting cover. The spray bar passes through the receiving space, the mounting base, and the mounting cover.

[0008] Through the above technical solution, each loose accessory can be placed in the storage space of the mounting base, eliminating the traditional method of placing each loose accessory in an accessory bag. When an accessory needs to be installed, simply remove the mounting cover from the spray nozzle to take out the corresponding accessory. Of course, when accessories need to be stored, simply place the corresponding accessory in the mounting position of the mounting base, then place the mounting base in the storage space, and install the mounting cover at the nozzle opening to complete the placement. The above structure makes reasonable use of the internal space of the spray nozzle, effectively reducing the probability of accessory loss and providing high convenience of use.

[0009] Preferably, the mounting base is integrally formed on the mounting cover.

[0010] Through the above technical solution, on the one hand, the mounting base and the mounting cover can be integrally injection molded, which can significantly reduce manufacturing costs; on the other hand, by fixing the mounting base to one side of the mounting cover, when the user removes the mounting cover from the spray nozzle, the mounting base and all the accessories installed on it can be removed at once, making the operation convenient.

[0011] Preferably, the mounting base and the mounting cover are designed as separate units, with the mounting base connected to the inner wall of the spray hood.

[0012] With the above technical solution, the mounting cover can be removed from the spray nozzle first, and the nozzle opening will be opened. The user can take out the accessories from the nozzle opening, which is more convenient. In addition, the mounting base, spray nozzle and mounting cover can be injection molded separately, and the injection mold structure is relatively simple.

[0013] Preferably, the mounting base and the inner wall of the spray hood are connected by snap-fit, threaded connection, or adhesive bonding.

[0014] Through the above technical solutions, if a snap-fit ​​or threaded connection is used, a detachable connection is achieved between the mounting base and the spray nozzle; if an adhesive connection is used, the connection stability between the spray nozzle and the mounting base can be effectively guaranteed.

[0015] Preferably, the mounting base is provided with a first fixing platform.

[0016] The above technical solution allows the adapter in the accessories to be fitted onto the first fixed platform, thereby fixing the conversion structure.

[0017] Preferably, the mounting cover has an annular protrusion, the spray bar passes through the annular protrusion, and the mounting base has a first clamping piece, forming a first clamping space between the first clamping piece and the annular protrusion.

[0018] Through the above technical solution, based on the columnar structure of the filter screen in the spray gun, the filter screen can be placed in the first clamping space between the first clamping plate and the annular protrusion, thereby achieving a stable fixing effect on the filter screen.

[0019] Preferably, the mounting cover is provided with two second clips, which are respectively located on both sides of the first clip, and a second clamping space is formed between the first clip and the second clips.

[0020] With the above technical solution, the spring in the accessory can be placed in the second clamping space. The two sides of the spring are held in place by two second clamping pieces, and the middle part of the spring is held in place by a first clamping piece, so that the spring can be firmly clamped in the second clamping space.

[0021] Preferably, the first clamping piece is provided with a clamping groove.

[0022] The above technical solution allows a ceramic disc with a spray hole in the middle to be placed in a clamping groove, thereby fixing the ceramic disc.

[0023] Preferably, the mounting cover is provided with a second fixing platform, the end of the second fixing platform is provided with at least two stepped surfaces, and the end of the second fixing platform extends into a mounting post.

[0024] With the above technical solution, at least two stepped surfaces can be used to place at least two different sizes of rubber pads, while the mounting column can be used to fix the O-ring.

[0025] The second objective of this invention is to provide a spray gun that can effectively reduce the probability of accessory loss and is highly convenient to use.

[0026] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: A spray gun, comprising the aforementioned storage structure.

[0027] With the above technical solution, different accessories are fixed between the spray nozzle and the mounting cover. The required accessories can be taken out by simply opening the mounting cover. When the accessories are not needed, they can be placed in the storage space. This spray gun makes reasonable use of the internal space of the spray nozzle, which can effectively reduce the chance of accessories being lost and is highly convenient to use.

[0030] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered. Example 1

[0031] A storage structure includes a spray nozzle 1 and a spray bar 2. The spray nozzle 1 has a receiving space 3.

[0032] It also includes a mounting cover 4 and a mounting base 5. The mounting base 5 is provided with a mounting position 6, which is used to fix loose accessories. The mounting cover 4 is installed at the opening of the spray nozzle 1, and the mounting base 5 is located in the accommodating space 3 between the spray nozzle 1 and the mounting cover 4. The mounting base 5 is preferably integrally formed with the mounting cover 4. The spray bar 2 passes through the receiving space 3, the mounting base 5, and the mounting cover 4.

[0033] Typically, the accessories for a spray gun mainly include an adapter 17, a filter screen 18, a spring 19, a ceramic disc 20, an O-ring 21, and a rubber pad 22. Considering that the shapes and sizes of these accessories vary, different mounting positions 6 need to be designed on the mounting base 5 for different accessories.

[0034] For fixing the adapter 17, a first fixing platform 7 is designed on the mounting base 5. In this embodiment, since there are two different models of adapters 17, the mounting base 5 is designed with two different sizes of first fixing platforms 7 to adapt and fix the corresponding adapters 17. The corresponding adapter 17 can be fitted into the end of the first fixing platform 7 to achieve fixation.

[0035] For fixing the columnar filter screen 18, an annular protrusion 8 is provided on the mounting cover 4. The spray rod 2 passes through the annular protrusion 8. A first clamping piece 9 is provided on the mounting base 5, and a first clamping space 10 is formed between the first clamping piece 9 and the annular protrusion 8. The outer cylindrical surface of the filter screen 18 is clamped between the first clamping piece 9 and the annular protrusion, which provides high fixing stability, makes full use of the internal space, and has a very compact structure.

[0036] For securing the spring 19, two second clips 11 are provided on the mounting cover 4. The two second clips 11 are located on both sides of the first clip 9, forming a second clamping space 12 between the first clip 9 and the second clips 11. The spring 19 is located below the filter screen 18. The two sides of the spring 19 are held abutted by the two second clips 11, and the middle of the spring 19 is held abutted by the first clip 9. This design can securely clamp the spring 19 within the second clamping space 12. This ingenious structural design makes full use of the internal space and has a very high degree of compactness.

[0037] For fixing the ceramic disc 20, the first clamping piece 9 is provided with a clamping groove 13. Since the ceramic disc 20 is relatively hard, it can be directly inserted into the clamping groove 13 to achieve a fixing effect.

[0038] For fixing the O-ring 21 and the rubber pad 22, a second fixing platform 14 is provided on the mounting cover 4. The end of the second fixing platform 14 has at least two stepped surfaces 15, and a mounting post 16 extends from the end of the second fixing platform 14. In this embodiment, the rubber pad 22 has two models and specifications. Each model and specification of the rubber pad 22 can be fixed on different stepped surfaces 15. Then, the O-ring 21 can also be fitted onto the mounting post 16 using its own elastic force.

[0039] To further improve the space utilization of the mounting base 5, a third fixing platform 23 can also be provided on the mounting base 5. The third fixing platform 23 is located between the two first fixing platforms 7, and a small end 24 can also be provided at the end of the third fixing platform 23 to provide a certain mounting position 6 for other available accessories. The component installed on the third fixing platform 23 shown in this embodiment is one of the accessories inside the spray gun nozzle.

[0040] The mounting structure on the mounting position 6 corresponding to each of the above accessories is ingeniously designed, with high space utilization, high installation stability, and easy to remove and place later.

[0041] Example 2: The difference from Example 1 is that: The mounting base 5 and the mounting cover 4 are designed as separate units, with the mounting base 5 connected to the inner wall of the spray hood 1. The mounting base 5 and the inner wall of the spray hood 1 are connected by snap-fit, threaded connection, or adhesive bonding.

[0042] Ideally, the mounting position on the mounting base 5 should face the mounting cover 4 so that the user can easily access the accessories on the mounting position. Example 3

[0043] A spray gun includes a receiving structure as shown in Embodiment 1 or Embodiment 2. Of course, the above are merely typical examples of the present invention. In addition, the present invention can have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
