Description

Technical Field

[0001] The utility model belongs to the technical field of drinking equipment and relates to a shell structure of an automatic wine dispenser. Background Art

[0002] Beer is a common beverage, and unlike canned beer, keg beer is more popular with consumers due to its flavor. As the name suggests, keg beer is beer that has been sealed in a barrel and then, to ensure easy access, a device called a dispenser is installed on the barrel to ensure it is readily available for consumption.

[0003] The wine dispenser in the prior art generally includes a shell with a cavity inside, and a battery, a motor, a valve body and a valve core are installed in the cavity of the shell, wherein the battery powers the motor, and the valve core is connected to the drive shaft of the motor and assembled together with the valve body. In addition, the wine dispenser also includes a wine delivery pipe and a wine outlet pipe, the wine delivery pipe is connected to the valve core and the wine spear respectively, and the wine outlet pipe is connected to the valve body. Under the driving action of the motor, the valve core moves relative to the valve body to open or close the wine path. In the open state, the wine in the wine barrel can pass through the wine spear, wine delivery pipe, valve core, valve body and finally through the wine outlet pipe to discharge the wine.

[0004] In order to ensure that components such as batteries, motors, valve bodies, valve cores, wine delivery pipes and wine outlet pipes can be installed, the outer shell is generally made into a split structure in the form of a main shell and a sub-shell, and the two parts are assembled in a detachable manner. The two parts can be disassembled and separated before assembly to ensure the convenience of component assembly and subsequent maintenance.

[0005] In the prior art, there are generally two ways to assemble and fix the main shell and the auxiliary shell, namely, snap-on connection and screw-on locking with fasteners. For the former, although disassembly and assembly are very convenient, the corresponding structural stability is poor, and there is often a risk of easy falling off between the main shell and the auxiliary shell. For the latter, during assembly, several holes on the main shell and several holes on the auxiliary shell need to be aligned one by one, which is inconvenient to operate. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems in the existing technology and propose a shell structure of an automatic wine dispenser. The technical problem to be solved by the present invention is: how to improve the firmness of the connection while ensuring the convenience of disassembly and assembly.

[0007] The objectives of the present invention can be achieved through the following technical solutions: A shell structure of an automatic wine dispenser, comprising a main shell and a rear shell, wherein a mounting port is provided on the upper surface of the main shell, and the rear shell is detachably connected to the main shell by fasteners, and is characterized in that a limiting groove is provided on the inner wall of the main shell along the circumferential direction and is arranged close to the mounting port, and the outer edge of the rear shell has a flange protruding toward the inner bottom wall of the main shell along the circumferential direction, the rear shell is embedded in the limiting groove and covers the mounting port, and several outer side walls of the flanges are in contact with the inner wall of the main shell.

[0008] The shell structure of the automatic wine dispenser is specifically composed of two parts: a main shell and a rear shell, wherein a mounting port is opened on the main shell, and the mounting port is used for assembling internal parts. After the assembly of the parts is completed, the rear shell and the main shell are detachably connected by fasteners to achieve the sealing of the mounting port on the main shell. Compared with the prior art, the difference of this application lies in that: this application arranges a limiting groove circumferentially close to the mounting port on the inner wall of the main shell, and before the rear shell is screwed and locked with screws, the outer edge of the rear shell is embedded in the limiting groove and abuts against the bottom wall of the limiting groove, so that the rear shell can seal the mounting port while the inner circumferential wall of the limiting groove is used. The circumference of the rear shell is also restricted. At the same time, a flange is provided on the outer edge of one side surface of the rear shell and protrudes toward the inner bottom wall of the main shell. When the rear shell is assembled, this specifically refers to the state where the rear shell has not yet been embedded in the limiting groove. In this state, the flange and the inner wall of the main shell are in contact with each other, so as to guide the embedding direction of the cover shell to avoid the outer edge of the rear shell and the inner circumferential wall of the limiting groove being always aligned. After that, the rear shell is restricted by the inner bottom wall and the inner circumferential wall of the limiting groove to ensure that the assembly of the rear shell is fast and convenient, and after that, the rear shell is screwed and locked to the main shell by fasteners to ensure the installation stability of the rear shell.

[0009] In the shell structure of the above-mentioned automatic wine dispenser, the installation port is opened on one side of the main shell and is set through the bottom of the main shell, the rear shell includes a vertical section set vertically and a horizontal section set horizontally, the limiting groove is U-shaped, and the limiting groove is opened on the inner wall of the installation port facing the vertical section, and the two ends of the limiting groove extend to the vertical section near the bottom edge, the top and both sides of the vertical section have abutment edges protruding outward relative to the flange side wall, and the abutment edges are embedded and limited in the limiting groove. The installation port is specifically opened on one side of the main shell and is set through the bottom of the main shell, and the rear shell composed of a vertical section and a horizontal section is L-shaped, the vertical section is used to cover the side of the installation port, and the horizontal section is used to cover the bottom of the installation port. The advantage of this arrangement is that a through hole can be formed between the bottom of the main shell and the rear shell for the wine outlet pipe to pass through, and there is no need to open another hole in the bottom of the main shell. In addition, it is worth mentioning that the limiting groove is opened on the inner wall of the vertical section opposite to the installation port. Since the installation port passes through the bottom wall of the main shell, the limiting groove is U-shaped, and the two ends of the limiting groove extend to the main shell near the bottom, that is, That is to say, the two ends of the limit groove are of closed design. When the rear shell is installed, the abutment edge formed on the periphery of the rear shell is embedded in the limit groove, and its two ends are supported by the inner walls at both ends of the limit groove, so as to ensure that after the abutment edge is embedded in the limit groove, the vertical part is limited in the vertical direction, and the rear shell is prevented from falling relative to the main shell, so as to ensure that both the rear shell and the main shell can maintain a high stability in the pre-installed state, and ensure the convenience of subsequent installation of fasteners. By limiting the vertical section of the rear shell through the cooperation of this structure, it can be ensured that the horizontal section of the rear shell also remains stable, effectively controlling the processing cost of the shell structure.

[0010] In the housing structure of the automatic wine dispenser described above, the flanges include a first flange formed at the top of the vertical section along the width of the vertical section, a plurality of second flanges formed on both sides of the vertical section along the length of the vertical section, and a third flange formed on both sides of the horizontal section along the length of the horizontal section, with the plurality of second flanges being spaced apart along the length of the vertical section. The flange structure is formed by the segmented arrangement of the first flange, the plurality of second flanges, and the third flange, ensuring that the flange has a guiding effect on the rear housing while reducing the overall structural strength of the flange, thereby ensuring that the flange has a certain degree of resistance to bending and folding.

[0011] In the housing structure of the automatic wine dispenser described above, a slot is provided between each two adjacent flanges on a side panel of the vertical section facing the inner bottom wall of the main housing. The inner walls on both sides of the main housing are provided with a plurality of connecting ribs, each end of which protrudes from the inner bottom wall of the limiting groove. These connecting ribs are plugged into the slots in a one-to-one correspondence. This arrangement allows the rear housing to be pre-installed in place, i.e., when it is inserted into and limited in the limiting groove against the edge, by means of the connecting ribs plugging into the slots in a one-to-one correspondence, thereby further ensuring the pre-installation stability of the rear housing.

[0012] In the housing structure of the automatic wine dispenser described above, each of the two adjacent flanges has a guide surface at one opposing end. The guide surface is formed on the side of the flange facing the inner bottom wall of the main housing, and the guide surface on one flange is tilted away from the other flange. When installing the rear housing, by providing the guide surfaces at the opposing ends of the two adjacent flanges, a guide structure is formed directly in front of each slot. When the rear housing is pushed in, if there is interference error, the guide structure can guide the connecting rib, ensuring that it can pass through the gap between the two adjacent flanges and fit into the slot.

[0013] In the housing structure of the automatic wine dispenser described above, the top inner wall of the main housing has two connecting seats whose outer end surfaces are flush with the bottom wall of the limiting groove. The bottom inner wall of the main housing has two connecting pieces protruding toward the vertical section. The top of the vertical section abuts against the two connecting seats and is screwed and locked with fasteners. The horizontal section overlaps the two connecting pieces and is screwed and locked with fasteners. By abutting the connecting seats against the vertical sections and screwing and locking with fasteners, and by overlapping the connecting pieces with the horizontal sections and screwing and locking with fasteners, the two ends of the rear housing are positioned, ensuring that the rear housing can be firmly positioned on the main housing to seal the mounting opening.

[0014] In the aforementioned automatic wine dispenser housing structure, the two connecting seats have a conical cross-sectional profile cut along the width of the vertical section, while the first flange has an isosceles trapezoidal cross-sectional profile cut along the width of the vertical section. The first flange is located between the two connecting seats, with both ends positioned adjacent to the two connecting seats. During installation, the two connecting seats can also guide the ends of the first flange through their outer walls, thereby assisting in correcting the installation and insertion direction of the rear housing, ensuring more convenient and quick installation of the rear housing.

[0015] In the housing structure of the automatic wine dispenser described above, the rear housing is provided with a plurality of spaced reinforcing ribs along the width of the rear housing at the junction of the vertical and horizontal sections. The ribs are triangular in shape, thereby increasing the connection strength between the vertical and horizontal sections and ensuring the overall structural stability of the rear housing.

[0016] Compared with the existing technology, the shell structure of this automatic wine dispenser has the following advantages:

[0017] The rear shell body is fitted with the inner wall of the main shell body through the flange to guide its own insertion direction, and the vertical section of the rear shell body is limited by the limit groove and the connecting rib is plugged into the slot opened on the vertical section, so that the rear shell body can be accurately and quickly installed and pre-fixed to seal the installation port, and the rear shell body is further screwed and locked with the main shell body by fasteners to ensure the installation firmness of the rear shell body.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6As shown, the shell structure of the automatic wine dispenser includes a main shell 1 and a rear shell 2. The main shell 1 is specifically hexahedral, with a mounting opening 11 on one side, and the mounting opening 11 is set through the bottom of the main shell 1. The rear shell 2 is L-shaped, which includes a vertical section 21 set along the vertical direction and a horizontal section 22 set along the horizontal direction, and a number of triangular reinforcing ribs 23 are integrally formed between the two.

[0027] like Figure 5 As shown, a limiting groove 12 is provided on the inner wall of the vertical section 21 of the main housing 1 facing the rear housing 2 along the circumferential direction and close to the edge of the mounting opening 11. The limiting groove 12 is specifically U-shaped and its two ends extend to the bottom edge of the main housing 1. Figure 6 As shown, outwardly protruding abutting edges 211 are formed on both sides and the top of the vertical section 21, and the abutting edges 211 are the same shape as the limiting groove 12, and the length, that is, the width, of the abutting edges 211 is slightly smaller than the limiting groove 12. A flange is provided along the circumferential direction on the rear shell body 2, and the flange includes a flange 1 212 formed along the horizontal direction at the top of the vertical section 21, a plurality of flange 213 formed on both sides of the vertical section 21, and a flange 3 221 formed on both sides of the horizontal section 22, wherein the plurality of flange 213 formed on both sides of the vertical section 21 are spaced apart along the length direction of the vertical section 21.

[0028] like Figure 5 As shown, a plurality of connecting ribs 13 are integrally formed on the inner walls of both sides of the main housing 1 and are in the shape of long strips, with the outer ends protruding from the inner bottom wall of the limiting groove 12. Figure 6 As shown, a slot 214 is provided on the plate surface of the vertical section 21 between two adjacent flanges 213, and the connecting rib 13 is positioned opposite the slot 214. In addition, a guide surface 2131 is provided at the opposite end of each two adjacent flanges 213, which is tilted away from each other, so that a flared guide structure is formed between the two adjacent flanges, and the guide surface 2131 is specifically formed on the side of the flange 213 facing the inner bottom wall of the main shell 1.

[0029] like Figure 5 As shown, on the inner wall of the top of the main shell 1, two outer end surfaces are formed along the width direction of the vertical section 21, and the connecting seat 14 is flush with the bottom wall of the limiting groove 12. The cross-sectional profile of the connecting seat 14 cut along the width direction of the vertical section 21 is conical. On the inner wall of the bottom of the shell, two connecting pieces 15 are formed along the width direction of the horizontal section 22, which are protruding toward the vertical section 21. Figure 4 As shown, the flange 212 is in the shape of an isosceles trapezoid.

[0030] Combine Figure 3 and Figure 4When assembling the main shell 1 and the rear shell 2, the worker holds the main shell 1 and the rear shell 2 respectively and plugs the two into each other so that the flange 1 212, the plurality of flanges 213 and the flange 3 221 are all in contact with the inner wall of the shell. The flange 1 212, the plurality of flanges 213 and the flange 3 221 limit the two sides of the rear shell 2 to prevent the rear shell 2 from being difficult to align with the installation opening 11 due to shaking during the insertion process, and the outer side surfaces of the two connecting seats 14 in the shell can cooperate with the surfaces at both ends of the flange 1 212 to achieve the effect of adjustment and correction. When assembled in place, the abutting edge 211 in this state is embedded in and limited in the limiting groove 12. The limiting groove 12 supports the limiting edge so that The rear shell 2 is limited in the vertical direction to prevent the rear shell 2 from falling relative to the main shell 1. At the same time, each connecting rib 13 is guided by the relative guide surface 2131 and passes through the gap between the two adjacent flanges 213 and is inserted into the slot 214, thereby further improving the connection stability between the rear shell 2 and the main shell 1. In this state, the vertical section 21 of the rear shell 2 and the two connecting seats 14 are abutted, and the horizontal section 22 and the connecting piece 15 are overlapped. The vertical section 21 and the connecting seat 14 are connected and locked by fasteners (i.e. screws), and the horizontal section 22 and the connecting piece 15 are connected and locked by fasteners (i.e. screws). The stable connection between the main shell 1 and the rear shell 2 is ensured, and it is ensured that the rear shell 2 can cover the installation port 11 of the main shell 1.
