Description
Technical Field
The disclosure relates to the technical field of fluid pipeline connection, in particular to a dispensing nozzle and a dispensing device.
Background
In the field of fluid line connection technology (e.g., refrigerant lines in refrigerators, compressor airflow lines in air conditioning systems, heat exchange fluid lines in heat exchange devices, other fluid connection lines, etc.), metal line connections are commonly used.
In the related art, the connection between the metal pipes is generally achieved by using a welding technique. However, in practice, the welding technique is not only time and labor consuming, but may also result in electrochemical corrosion and sparking operation, especially with manual welding techniques, which have poor weld stability and high weld defect rates.
In the related art, the connection between the metal pipes can also be realized by using a solderless technology, for example, a spot gluing technology. Specifically, fluid adhesive is coated on the metal pipeline connecting points through an adhesive dispenser to realize the connection between the metal pipelines. The adoption of the adhesive dispensing technology can avoid the disadvantages of various technologies brought by the welding technology. However, when the conventional dispensing and bonding technique is used, when the dispenser is used to apply the fluid adhesive around the outer diameter surface of the pipe at the connecting point of the metal pipes, there are still disadvantages that the fluid adhesive application time is long (for example, it takes about 30 seconds to perform the fluid adhesive application operation at one connecting point of the metal pipes), the fluid adhesive application is not uniform, and the like.

Detailed Description
While the present disclosure will be fully described with reference to the accompanying drawings, which contain preferred embodiments of the disclosure, it should be understood before this description that one of ordinary skill in the art can modify the disclosure described herein while obtaining the technical effects of the present disclosure. Therefore, it should be understood that the foregoing description is a broad disclosure directed to persons of ordinary skill in the art, and that there is no intent to limit the exemplary embodiments described in this disclosure.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in diagram form to simplify the drawing.
According to the general inventive concept of the present disclosure, there is provided a dispensing nozzle including: the dispensing device comprises a first dispensing member with a first inner concave surface and a second dispensing member with a second inner concave surface. At least one of the first and second inner concave surfaces has a spray opening formed thereon. The first dispensing member and the second dispensing member are independent of each other and are capable of cooperating with each other such that the first inner concave surface and the second inner concave surface form an annular spraying surface around the outer diameter surface of the object to be sprayed. Meanwhile, still provide a dispensing device, include: a dispensing nozzle as described above, and a fluid supply assembly connected to the fluid spray nozzle.
Referring to fig. 1 to 5, according to an embodiment of the present disclosure, there is provided a dispensing nozzle 100 including: a first dispensing member 1 having a first inner concave surface 10, and a second dispensing member 2 having a second inner concave surface 20. At least one of the first and second inner concave surfaces 10 and 20 has a spray opening 6 formed thereon. The first dispensing member 1 and the second dispensing member 2 are independent of each other and can cooperate with each other such that the first inner concave surface 10 and the second inner concave surface 20 together form an annular spraying surface around an outer diameter surface of an object to be sprayed (e.g., a metal pipe connection point, not shown).
In the present disclosure, the expression "the first dispensing member and the second dispensing member are independent of each other" may mean that: the first dispensing member and the second dispensing member are independent components, and no fluid communication and/or exchange relationship exists.
That is, in the dispensing nozzle provided in the embodiments of the present disclosure, the first and second dispensing members are independent components, and both have inner concave surfaces adapted to the outer diameter surface of the object to be sprayed. Structurally, when the first dispensing member and the second dispensing member are matched with each other, the inner concave surfaces of the first dispensing member and the second dispensing member form an annular spraying surface with a spraying opening together. Thus, the dispensing nozzle provided by the embodiment of the present disclosure, the first and second dispensing members independent of each other are assembled and assembled with each other, and can be sleeved outside the outer diameter surface of the object to be sprayed, and at this time, the annular spraying surface formed by the inner concave surfaces of the first and second dispensing members together surrounds the outer diameter surface of the object to be sprayed, so that the dispensing nozzle can conveniently perform dispensing operation on the outer diameter surface of the object to be sprayed along the radial direction of the object to be sprayed. Moreover, when the dispensing operation is completed, the first and second dispensing members assembled with each other can be easily separated from each other, and thus can be easily detached from the object to be sprayed. In other embodiments, the first dispensing member and the second dispensing member may also be hinged together in a removable manner. According to an embodiment of the present disclosure, the first dispensing member and the second dispensing member are made of any one of the following materials: metal, plastic, rubber, wood, and ceramic, but are not limited thereto as long as they can be suitably used to manufacture a nozzle for spraying a fluid gel.
According to the embodiment of the disclosure, the first inner concave surface of the first dispensing member and the second inner concave surface of the second dispensing member may both have a spraying opening formed thereon. For example, the first inner concave surface of the first dispensing member and the second inner concave surface of the second dispensing member may each have a single or a plurality of spray openings formed thereon. In the dispensing nozzle shown in the embodiments of fig. 1 to 5, the first inner concave surface of the first dispensing member and the second inner concave surface of the second dispensing member may each have a spraying opening array formed by a plurality of spraying openings. For example, the array of spray orifices occupies an area in the annular spray surface that is about 5% to 95% of the total area of the annular spray surface. In an exemplary embodiment, the array of spray orifices may occupy an area in the annular spray surface of about 30-60% of the total area of the annular spray surface. According to the dispensing nozzle provided by the embodiment of the disclosure, the plurality of spraying ports or the spraying port arrays are uniformly distributed on the first inner concave surface of the first dispensing member and the second inner concave surface of the second dispensing member, so that the fluid adhesive can be uniformly coated on the outer diameter surface of the object to be sprayed, and the dispensing quality is improved.
According to an embodiment of the present disclosure, the cross-sectional shape of the spray opening, whether one or more spray openings or an array of spray openings, comprises any one of the group of: circular, triangular, rectangular, hexagonal, rectilinear slots, curvilinear slots, pentagonal, heart-shaped, or combinations thereof. Exemplarily, (a) to (d) in fig. 6 show respective embodiments in which the spray opening arrays have spray openings with different sectional shapes, respectively. For example, (a) in fig. 6 shows that the spray opening 6 has a circular sectional shape; fig. 6 (b) shows that the spray opening 6 has a rectangular sectional shape; fig. 6 (c) shows that the spray opening 6 has a triangular sectional shape; fig. 6 (d) shows that the spray opening 6 has a linear groove cross-sectional shape. While various embodiments of the spray ports having different cross-sectional shapes have been described above, it will be appreciated by those skilled in the art that the present disclosure is not limited thereto, as long as the spray ports having any regular or irregular cross-sectional shape can be designed as desired to achieve the spray of the fluid adhesive. In an exemplary embodiment, the spray opening 6 has a circular cross-sectional shape, which may further facilitate the flow and spraying of the fluid gel. In addition, the number and distribution of the spray openings/arrays of spray openings on the inner concave surface may also vary in different embodiments. Illustratively, fig. 7 (a) to (e) show various embodiments in which the spray openings/spray opening arrays on the inner concave surface have different distribution patterns, respectively. For example, fig. 7 (a) shows that the spray opening array is divided into three rows of the spray openings 6, each row having a plurality of the spray openings 6; fig. 7 (b) shows that the spray opening array is divided into two rows of the spray openings 6, each row having a plurality of the spray openings 6; fig. 7 (c) shows that the spray opening array is only one row of the spray openings 6 formed by the plurality of spray openings 6; fig. 7 (d) shows that the spray opening array is only one row of the spray openings 6 formed by the plurality of spray openings 6; fig. 7 (e) shows that each inner concave surface has only one spraying opening 6. While various embodiments of the distribution of the spray orifices/arrays of spray orifices on the inner concave surface are set forth above, it will be appreciated by those skilled in the art that the present disclosure is not limited thereto. It is noted that in the exemplary embodiment, the spray orifices/arrays of spray orifices on the inner concave surface are distributed at a mid-portion 12 (described in detail below) of the inner concave surface.
According to the embodiments of the present disclosure, with respect to the structures and shapes of the first and second dispensing members, no limitation is imposed on the structures and shapes of the first and second dispensing members other than the inner concave surfaces, except that the first and second inner concave surfaces are required to be able to form the annular spray surface in common so as to surround the outside of the outer diameter surface of the object to be sprayed. Therefore, the first and second dispensing members may have different structures and shapes in addition to the structure and shape of the inner concave surface. That is, the first and second dispensing members may be identical or different in structure and shape except for the inner concave surface; and may be partially identical and partially different, as the present disclosure does not limit thereto. In the exemplary embodiment shown in fig. 1 to 5, the first and second dispensing members have the same structure and shape, which may further facilitate the flow and spraying of the fluid glue. In an exemplary embodiment, the first and second dispensing members have the same structure and shape, which may facilitate mass production of the dispensing members, for example. For example, in the embodiment shown in fig. 1, each of the first dispensing member 1 and the second dispensing member 2 has a main body portion with a substantially half cylindrical structure, so that the first concave surface 10 of the first dispensing member 1 and the second concave surface 20 of the second dispensing member 2 are each a semicircular concave arc surface, and accordingly, the annular spraying surface formed by the first and second concave surfaces together is a cylindrical concave surface having an axis. Hereinafter, for the sake of clarity, only the structure, shape and the like of the various parts of the first dispensing member 1 will be described with reference to fig. 2 to 12, and it will be understood by those skilled in the art that these descriptions of the first dispensing member 1 can also be applied to the second dispensing member 2, and the structure, shape and the like of the second dispensing member 2 will not be described in detail hereinafter.
According to an embodiment of the present disclosure, referring to fig. 4 and 5, along the direction of the axis of the first inner concave surface 10 of the first gutta-percha member 1 (where the axis may be located at the intersection of the symbols r1 and r2 in the embodiment as shown in fig. 5), the inner concave surface 10 of the first gutta-percha member 1 includes two end portions 12 and an intermediate portion 13 located between the two end portions 12. As shown in fig. 4 and 5, in the direction perpendicular to the axial direction, a dimension r2 (where the dimension r2 may be the radius of the concave arc end portion 13 in the embodiment shown in fig. 5) of both end portions 13 of the first inner concave surface 10 in the axial direction is smaller than a dimension r1 (where the dimension r1 may be the radius of the concave arc middle portion 12 in the embodiment shown in fig. 5) of the first inner concave surface 10 in the axial direction, which is located between the both end portions 13. Of course, the dimensions r1 and r2 described herein are both required to be larger than the corresponding dimensions of the object to be painted (e.g., the radius of the object to be painted), so that the inner concave surface 10 of the first spot gluing member 1 can surround the outer diameter surface of the object to be painted. Here, the dimension r2 of the end portion 13 of the first inner concave surface 10 may be considered to be designed to be equal to or slightly larger than the corresponding dimension of the object to be painted, while the dimension r2 of the end portion 13 of the first inner concave surface 10 is designed to be smaller than the dimension r1 of the intermediate portion 12. Thus, when the inner concave surface 10 of the first spot gluing member 1 surrounds the outer diameter surface of the object to be sprayed, a gap exists between the outer diameter surface of the object to be sprayed and the size r1 of the middle part 12 of the first inner concave surface 10, so that a spraying space can be provided for the fluid glue sprayed from the spraying opening 6, and the fluid glue is favorably and uniformly distributed on the outer diameter surface of the object to be sprayed.
According to an embodiment of the present disclosure, referring to fig. 2 to 5, the first dispensing member 1 is provided with a fluid connector 4 for fluid communication with an external fluid supply assembly (which will be explained and explained in the following description of the dispensing device) to serve as a fluid inlet, and the fluid connector 4 is in communication with the spraying port 6. The fluid junction 4 is an inlet for the spray fluid (fluid glue inlet), and the spray port 6 is a spray outlet for the spray fluid (glue outlet). Specifically, as shown in fig. 3, the fluid connector 4 is provided on the outer surface 14 of the first mastic member 1 and includes an outer contour and a fluid passage defined by the outer contour. The fluid connector 4 may take different shapes. Exemplarily, (a) to (d) in fig. 8 show respective embodiments of different cross-sectional shapes of the fluid junction in the dispensing member, respectively. For example, (a) in fig. 8 shows that both the outer contour of the fluid connector 4 and the fluid passage are circular in sectional shape; fig. 8 (b) shows that the outer contour of the fluid connector 4 is a rectangular sectional shape and the fluid passage is a circular sectional shape; fig. 8 (c) shows that the outer contour of the fluid connector 4 is a hexagonal sectional shape and the fluid passage is a circular sectional shape; fig. 8 (d) shows that the outer contour of the fluid connector 4 and the fluid passage are both rectangular in cross-sectional shape. Although various embodiments of fluid connectors having different cross-sectional shapes are given above, it will be understood by those skilled in the art that the present disclosure is not limited thereto, as long as the delivery of the fluid gel can be achieved, and fluid connectors having any regular or irregular cross-sectional shape can be designed according to actual needs. In the exemplary embodiment, the outer contour of the fluid connector 4 and the fluid passage are both circular in cross-sectional shape.
Further, as shown in fig. 4 and 5, a cavity 5 for storing the fluid paste may be formed inside the first paste applying member 1, and the fluid connector 4 is communicated with the spraying port 6 via the cavity 5. In addition, as shown in fig. 2, 3 and 5, the fluid connector 4 is formed with a barb structure 15 so that the fluid connector 4 can be stably and effectively connected to the fluid supply port of the external fluid supply assembly. The number and specific shape of the barb structures 15 are not limited, and illustratively, in the illustrated embodiment, three annular barb structures 15 are formed on the fluid connector 4.
According to an embodiment of the present disclosure, referring to fig. 2 to 5, a connector 7 for connecting to an external fluid supply assembly is formed on the first dispensing member 1. As shown in fig. 3, the connecting member 7 may be provided on the outer surface 14 of the first mastic member 1. However, the shape of the connectors 7 and the specific location and number of connectors 7 on the outer surface 14 of the first mastic member 1 may vary as desired. Exemplarily, (a) to (c) in fig. 9 show respective embodiments of different cross-sectional shapes of the connecting member 7 in the dispensing member, respectively. For example, (a) in fig. 9 shows that the connecting member 7 has a rectangular sectional shape; fig. 9 (b) shows that the connecting member 7 has a triangular sectional shape; fig. 9 (c) shows that the connecting member 7 has a circular sectional shape. Although various embodiments of the connecting member 7 having different sectional shapes are given above, it should be understood by those skilled in the art that the connecting member 7 having any regular or irregular sectional shape may be designed according to actual needs, and the present disclosure is not limited thereto. In the exemplary embodiment, the connecting piece 7 has a rectangular cross-sectional shape. Further, (a) to (c) in fig. 10 show respective embodiments of the connecting members 7 in different numbers and/or different positions in the dispensing member. For example, fig. 10 (a) shows a connecting member 7 located on the outer surface of the dispensing member 1 and arranged substantially perpendicular to the fluid connector 4; fig. 10 (b) shows a connecting member 7 located on the outer surface of the dispensing member 1 and arranged substantially obliquely to the fluid connector 4; fig. 10 (c) shows two connectors 7 on the outer surface of the dispensing member 1, one connector 7 being arranged substantially perpendicular to the fluid connector 4 and the other connector 7 being arranged substantially obliquely to the fluid connector 4. Although various embodiments having different numbers and/or different positions of the connecting members 7 are given above, it should be understood by those skilled in the art that any position or number of the connecting members 7 can be designed according to actual needs, and the present disclosure is not limited thereto.
According to the embodiment of the present disclosure, the inner concave surface 10 of the first spot gluing member 1 may also have different cross-sectional shapes to match with the outer diameter surfaces of objects to be sprayed with different cross-sectional shapes. Exemplarily, (a) to (c) in fig. 11 show various embodiments of the concave surface 10 having different cross-sectional shapes in the dispensing member, respectively. For example, (a) in fig. 11 shows that the inner concave surface 10 has a circular arc sectional shape; fig. 11 (b) shows that the inner concave surface 10 has a rectangular sectional shape; fig. 11 (c) shows that the inner concave surface 10 has an oblong sectional shape. Although various embodiments of the inner concave surface 10 having different sectional shapes are given above, it should be understood by those skilled in the art that the inner concave surface 10 having any sectional shape is designed according to actual needs to match objects to be sprayed having different outer diameter surface profiles, and the present disclosure is not limited thereto. In an exemplary embodiment, the inner concave surface 10 has a circular arc sectional shape.
Furthermore, the outer surface 14 of the first gum member 1 may also have a different cross-sectional shape. Exemplarily, (a) to (c) in fig. 12 show respective embodiments of the outer surface 14 having different cross-sectional shapes in the dispensing member, respectively. For example, (a) in fig. 12 shows that the outer surface 14 has a circular arc-shaped sectional shape; fig. 12 (b) shows that the outer surface 14 has a rectangular sectional shape; fig. 12 (c) shows that the outer surface 14 has a half-hexagonal sectional shape. While various embodiments of the outer surface 14 having different cross-sectional shapes are presented above, those skilled in the art will appreciate that the outer surface 14 having any cross-sectional shape may be designed according to actual needs and the present disclosure is not limited thereto. In the exemplary embodiment, outer surface 14 has a circular arc cross-sectional shape.
On the other hand, the embodiment of the disclosure further provides a dispensing device. Referring to fig. 13 and 14, the dispensing apparatus includes: the dispensing nozzle 100 according to any of the preceding embodiments, the fluid supply assembly 200 connected to the dispensing nozzle 100, and the clamping tool 300. The first dispensing member 1 and the second dispensing member 2 of the dispensing nozzle 100 are respectively connected to the holding tool 300.
As shown in fig. 13, the fluid supply assembly 200 includes: the adhesive dispensing nozzle comprises an adhesive container 210 and an adhesive flow pipeline 220, wherein an adhesive outlet of the adhesive container 210 is communicated with the adhesive flow pipeline 220, and the adhesive flow pipeline 220 is respectively connected to the fluid connectors 4 of the first dispensing member 1 and the second dispensing member 2, so that the fluid adhesive is supplied to the dispensing nozzle 100.
As shown in fig. 14, the holding tool 300 further includes: a connecting groove 301 of a connecting piece respectively connecting the first dispensing member and the second dispensing member; fastening holes 302 for respectively fixing the connection members of the first dispensing member and the second dispensing member to the connection grooves using fastening elements; and an elastic element 303 for clamping the first dispensing member and the second dispensing member to obtain an annular spraying surface.
Thus, when the dispensing device provided by the embodiment of the present disclosure needs to be used, as shown in fig. 14, the connecting pieces 7 of the first member 1 and the second member 2 are respectively inserted into the two connecting grooves 301 of the clamping tool 300, and the first member 1 and the second member 2 are fixed to the clamping tool 300 by the cooperation of the fastening element and the fastening hole 302, at this time, under the elastic action of the elastic element 303, the inner concave surfaces of the first member 1 and the second member 2 constitute an annular spraying surface. Next, before the dispensing operation needs to be performed, the preparation before the dispensing operation can be completed by connecting the fluid connectors 4 of the first member 1 and the second member 2 to the fluid supply assembly (including the fluid feed system and the feed tube). In use, the first member 1 and the second member 2 can be moved away from each other by simply overcoming the elastic force of the elastic element 303 through the handle, thereby conveniently assembling the fluid nozzle 100 to the outer diameter surface of the object to be sprayed. And then, the glue dispensing operation can be carried out on the outer diameter surface of the object to be sprayed along the radial direction of the object to be sprayed. After the dispensing operation is completed, the first member 1 and the second member 2 are moved away from each other again by the handle against the elastic force of the elastic element 303, thereby facilitating the detachment of the fluid nozzle 100 from the outer diameter surface of the object to be sprayed.
As can be seen from the above, the dispensing nozzle and the dispensing apparatus provided in the embodiments of the present disclosure can be quickly and conveniently assembled and assembled onto the outer diameter surface of the object to be sprayed (e.g., the metal pipe connection point) during use, and can be quickly and conveniently disassembled from the outer diameter surface of the object to be sprayed, because the dispensing nozzle includes the first and second dispensing members that are independent of each other. Therefore, the dispensing nozzle and the dispensing device provided by the embodiment of the disclosure are simple in structure and convenient to operate. According to the dispensing nozzle and the dispensing device provided by the embodiment of the disclosure, since the spraying ports of the dispensing nozzle for spraying the fluid glue are formed on the inner concave surfaces of the first and second dispensing members, after the first and second dispensing members are assembled and assembled to the outer diameter surface of the object to be sprayed (for example, a metal pipeline connecting point), the dispensing operation can be conveniently performed on the outer diameter surface of the object to be sprayed along the radial direction of the object to be sprayed by using the spraying ports distributed on the inner concave surfaces of the first and second dispensing members. In addition, since the sizes of the two end portions of the inner concave surfaces of the first and second dispensing members along the axial direction are smaller than the size of the middle portion of the inner concave surfaces of the first and second dispensing members along the axial direction between the two end portions, the first and second dispensing members have a proper gap with the outer diameter surface of the object to be sprayed, which facilitates the distribution of the sprayed fluid adhesive. In addition, each of the first and second dispensing members has a fluid connector, a cavity and a spraying port communicating with each other, and thus each of the first and second dispensing members can independently perform fluid paste application. Therefore, the dispensing nozzle and the dispensing device structure provided by the embodiment of the disclosure can effectively shorten the fluid adhesive coating time and can ensure uniform fluid adhesive coating.
It will be appreciated by those skilled in the art that the embodiments described above are exemplary and can be modified by those skilled in the art, and that the structures described in the various embodiments can be freely combined without conflict in structure or principle.
Having described in detail the above exemplary embodiments of the present disclosure, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope and spirit of the appended claims, and the disclosure is not limited to the embodiments of the exemplary embodiments set forth in the specification.
