Description

Technical Field

[0001] This application relates to the field of drinking equipment technology, and in particular to a core mechanism and a dispenser. Background Technology

[0002] A dispenser is used to connect to a fluid storage device to draw fluid out of the device. For example, a dispenser can be installed on top of a beer keg and works with a beer spout inside to draw out the beer. In related technologies, the operator operates the dispenser by turning a handle to move a pusher inside the dispenser, which in turn opens a valve on the beer spout, thus opening the flow path and allowing the beer to be drawn out.

[0003] Considering factors such as manufacturing costs and ease of assembly / disassembly, the top core inside the distributor often adopts a split design, for example, by connecting an upper and lower top core to form a single top core. However, when force is applied to the top core via the handle to transmit force to the valve core, the connection between the upper and lower top cores may deform, causing the connection to unlock. This makes it impossible for the upper and lower top cores to maintain a stable connection, reducing the stability of the distributor's operation. Utility Model Content

[0004] Therefore, it is necessary to provide a core mechanism and a distributor to address the aforementioned technical problems.

[0005] A core mechanism, the core mechanism comprising:

[0006] Upper core, the upper core having a connecting groove;

[0007] A lower top core, which is inserted into the upper top core via the connecting groove, wherein the lower top core is provided with a limiting step, the limiting step being configured to limit the upper top core in the insertion direction of the lower top core and the upper top core; and

[0008] A reinforcing member is disposed on the limiting step and is located between the limiting step and the upper core in the insertion direction.

[0009] In one embodiment, the hardness of the reinforcing member is greater than the hardness of the upper mandrel and the lower mandrel; and / or

[0010] The limiting step is arranged around the inner side of the lower top core in the circumferential direction, and the reinforcing member is a ring structure that cooperates with the limiting step.

[0011] In one embodiment, the top core mechanism further includes a limiting component connected to the upper top core, at least a portion of the limiting component protruding from the upper top core for engaging with the limiting step and the reinforcing member for limiting.

[0012] In one embodiment, the upper core is provided with a first mounting groove and a second mounting groove that are interconnected.

[0013] The limiting component includes a first limiting member and a second limiting member. The first limiting member passes through the first mounting groove and extends out of the first mounting groove to cooperate with the limiting step and the reinforcing member for limiting. The second limiting member passes through the second mounting groove and extends into the first mounting groove and contacts the first limiting member.

[0014] In one embodiment, the second limiting member is disposed on the side of the first limiting member opposite to the reinforcing member; and / or

[0015] The extension direction of the first mounting slot is parallel to the insertion direction; and / or

[0016] The second mounting groove extends perpendicularly to the insertion direction.

[0017] In one embodiment, the first limiting member includes an elastic portion and a first limiting portion, one end of the elastic portion is connected to the bottom of the first mounting groove, the other end of the elastic portion is connected to the first limiting portion, and the first limiting portion is configured to extend out of the first mounting groove under the elastic force of the elastic portion.

[0018] In one embodiment, the second limiting member includes a second limiting part and a positioning part. The second limiting part passes through the second mounting groove, one end of the second limiting part extends into the first mounting groove and contacts the first limiting member, and the positioning part is connected to the other end of the second limiting part and protrudes from the side wall of the second limiting part. The positioning part is located outside the second mounting groove and abuts against the upper core.

[0019] In one embodiment, the end of the second limiting part that extends into the first mounting groove is provided with a limiting notch, and the limiting notch is attached to the outer surface of the first limiting member.

[0020] In one embodiment, the limiting notch is coaxially arranged with the first limiting member.

[0021] A dispenser comprising the core mechanism described in any of the preceding claims.

[0022] The aforementioned top core mechanism and distributor, through the above structural design, allow the upper and lower top cores to be inserted relative to each other during assembly. The lower top core is inserted into the connecting groove of the upper top core, while the limiting step on the lower top core, in conjunction with the reinforcing member, blocks and limits the movement of the upper top core, achieving vertical positioning of both the upper and lower top cores. Because the reinforcing member is located on the limiting step of the lower top core, it enhances the support force of the lower top core on the upper top core. This ensures that when the upper top core tends to move downwards, the lower top core provides stable support, guaranteeing a stable connection between the upper and lower top cores and improving the stability of the distributor.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] See Figure 1 As shown, Figure 1 A cross-sectional view of the dispenser 1 in an embodiment of this application is shown. The dispenser 1 provided in this embodiment includes a core mechanism 10. The core mechanism 10 has a stable connection state, which can ensure the stability of the dispenser 1 during use. (Continue reading) Figures 1 to 5 As shown, the top core mechanism 10 provided in this application embodiment includes an upper top core 100 and a lower top core 200 that can move relative to each other, and a reinforcing member 300 disposed between the upper top core 100 and the lower top core 200. The reinforcing member 300 supports the upper top core 100 and the lower top core 200, making the connection between the upper top core 100 and the lower top core 200 less prone to compression and deformation, thereby improving the connection stability of the upper top core 100 and the lower top core 200, thus solving the problem of unstable limiting state of the upper top core 100 and the lower top core 200 in the existing distributor 1.

[0042] The upper top core 100 and the lower top core 200 are arranged in the same direction. For example, when the upper top core 100 and the lower top core 200 are distributed along the direction of gravity, the upper top core 100 is located above the lower top core 200. The upper top core 100 has a connecting groove 121 for the lower top core 200 to be inserted into the upper top core 100. For example, in some embodiments, the upper top core 100 includes an outer tube portion 110, a connecting portion 120, and an inner sleeve 130. The outer tube portion 110 has an annular structure, and the inner sleeve 130 has a cylindrical structure. The outer tube portion 110 is sleeved on the outer periphery of the inner sleeve 130. The connecting portion 120 connects the outer tube portion 110 and the inner sleeve 130, and the connecting portion 120 together with the outer tube portion 110 and the inner sleeve 130 forms an annular connecting groove 121.

[0043] The lower top core 200 has a generally cylindrical structure. The top end of the lower top core 200 is inserted into the connecting groove 121 to connect with the upper top core 100 via the connecting groove 121. A limiting step 210 is provided on the inner sidewall of the lower top core 200. The limiting step 210 is configured to limit the upper top core 100 in the insertion direction between the lower top core 200 and the upper top core 100. It should be noted that the insertion direction in this embodiment refers to... Figure 1 The vertical direction in the text is the direction of gravity. For ease of understanding, the insertion direction in the following text can be referred to here.

[0044] A reinforcing member 300 is disposed on the limiting step 210, and the reinforcing member 300 is located between the limiting step 210 and the upper core 100 in the insertion direction. For example, the reinforcing member 300 can be arranged on the side of the limiting step 210 facing the upper core 100 in the insertion direction by means of snap-fit, adhesive, etc. When the lower core 200 and the upper core 100 are inserted, one side of the reinforcing member 300 is attached to the surface of the limiting step 210, and the other side of the reinforcing member 300 is used to support the upper core 100, thereby limiting the upper core 100 in the insertion direction.

[0045] Through the above structural design, when the upper top core 100 and the lower top core 200 are assembled, they are inserted relative to each other, so that the lower top core 200 is inserted into the connecting groove 121 of the upper top core 100. At the same time, the limiting step 210 on the lower top core 200 cooperates with the reinforcing member 300 to block and limit the upper top core 100, thereby achieving vertical positioning of the upper top core 100 and the lower top core 200. Since the reinforcing member 300 is provided on the limiting step 210 of the lower top core 200, the supporting force of the lower top core 200 on the upper top core 100 is increased by the reinforcing member 300. Thus, when the upper top core 100 tends to move downward, the lower top core 200 can provide stable support for the upper top core 100, ensuring that the upper top core 100 and the lower top core 200 can maintain a stable connection state and improving the stability of the distributor 1.

[0046] In some embodiments, the hardness of the reinforcing member 300 is greater than that of the upper core 100 and the lower core 200. For example, the upper core 100 and the lower core 200 are often made of plastic. However, because plastic is not hard enough, when pressed forcefully, the limiting step 210 at the connection between the upper core 100 and the lower core 200 may be deformed, causing the upper core 100 and the lower core 200 to lose their vertical limiting position. In this case, the reinforcing member 300 can be made of metal. Using a reinforcing member 300 with higher hardness can help increase the supporting force of the limiting step 210 on the upper core 100, thereby improving the connection stability of the upper core 100 and the lower core 200.

[0047] In some embodiments, the limiting step 210 is disposed circumferentially around the inner side of the lower top core 200, and the reinforcing member 300 is an annular structure that mates with the limiting step 210. (See also...) Figure 2 , Figure 3 and Figure 5 As shown, the limiting steps 210 are distributed in a ring on the inner wall of the lower top core 200. Correspondingly, the reinforcing member 300 has a ring-shaped sheet structure and is disposed on the limiting steps 210. Thus, on the one hand, it is convenient for the upper top core 100 and the lower top core 200 to be directly inserted, thereby completing the assembly quickly; on the other hand, the reinforcing member 300 can be used to enhance the structural strength of the lower top core 200 and improve its stability.

[0048] See Figures 1 to 2 As shown, in some embodiments, the top core mechanism 10 further includes a limiting component 400 connected to the upper top core 100. At least a portion of the limiting component 400 protrudes from the upper top core 100 to cooperate with the limiting step 210 and the reinforcing member 300 for limiting. Specifically, the limiting component 400 protrudes radially from the side of the upper top core 100. When the upper top core 100 and the lower top core 200 are assembled, the portion of the limiting component 400 protruding from the upper top core 100 can abut against the reinforcing member 300 on the limiting step 210 on the lower top core 200, thereby achieving vertical positioning of the upper top core 100 and the lower top core 200, and maintaining a stable connection between the upper top core 100 and the lower top core 200.

[0049] Further, see Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, the upper core 100 is provided with a first mounting groove 131 and a second mounting groove 132 that are interconnected. For example, in some embodiments, the extending direction of the first mounting groove 131 is parallel to the insertion direction, and the extending direction of the second mounting groove 132 is perpendicular to the insertion direction. Specifically, the outer wall of the inner sleeve 130 is provided with a first mounting groove 131 that is arranged horizontally, and the top end of the inner sleeve 130 is provided with a second mounting groove 132 that is arranged vertically, and the bottom end of the second mounting groove 132 is connected to the first mounting groove 131.

[0050] The limiting assembly 400 includes a first limiting member 410 and a second limiting member 420. The first limiting member 410 passes through the first mounting groove 131 and extends out of the first mounting groove 131 to cooperate with the limiting step 210 and the reinforcing member 300 for limiting. Specifically, the first limiting member 410 is installed in the first mounting groove 131 of the inner sleeve 130. The end of the first limiting member 410 away from the inner sleeve 130 extends out of the first mounting groove 131. When the upper top core 100 moves relative to the lower top core 200 until the end of the first limiting member 410 abuts against the reinforcing member 300 located on the limiting step 210, the upper top core 100 and the lower top core 200 are vertically limited.

[0051] The second limiting member 420 passes through the second mounting groove 132 and extends into the first mounting groove 131, contacting the first limiting member 410. For example, in some embodiments, the second limiting member 420 is located on the side of the first limiting member 410 away from the reinforcing member 300. Specifically, the second limiting member 420 is installed in the second mounting groove 132 of the inner sleeve 130. The second limiting member 420 is configured as a thin plate-shaped tooling. The bottom end of the second limiting member 420 extends into the first mounting groove 131 and contacts the outer surface of the first limiting member 410, thereby limiting the first limiting member 410 by the second limiting member 420 to ensure that the first limiting member 410 is installed securely.

[0052] Optionally, the second limiting member 420 may be made of a plastic material with high hardness or a metal material, and the second limiting member 420 may be directly welded to the inner sleeve 130, thereby improving the stability of limiting the first limiting member 410.

[0053] In some embodiments, the first limiting member 410 includes an elastic portion 411 and a first limiting portion 412. One end of the elastic portion 411 is connected to the bottom of the first mounting groove 131, and the other end of the elastic portion 411 is connected to the first limiting portion 412. The first limiting portion 412 is configured to extend out of the first mounting groove 131 under the elastic force of the elastic portion 411. For example, see... Figure 1 , Figure 2 and Figure 5As shown, the elastic part 411 can be a spring, and the first limiting part 412 can be cylindrical. Correspondingly, the first mounting groove 131 is a cylindrical groove. One end of the elastic part 411 is fixedly connected to the bottom surface of the first mounting groove 131, and the other end of the elastic part 411 is fixedly connected to the first limiting part 412. Furthermore, the elastic part 411 is in a compressed state, giving it a tendency to push the first limiting part 412 away from the first mounting groove 131. Thus, the elastic force provided by the elastic part 411 can push the first limiting part 412 out of the first mounting groove 131, ensuring that the length of the portion of the first limiting part 412 extending out of the first mounting groove 131 is sufficiently long to facilitate the cooperation between the first limiting part 412 and the limiting step 210 and the reinforcing member 300, thereby achieving a better limiting effect and improving the limiting efficiency.

[0054] Furthermore, since the first limiting part 412 and the elastic part 411 are designed separately, the first limiting part 412 can be made of a material with higher hardness, which is conducive to cooperating with the reinforcing member 300, thereby providing better support and limiting function.

[0055] In some embodiments, the second limiting member 420 includes a second limiting portion 421 and a positioning portion 422. The second limiting portion 421 passes through the second mounting groove 132, with one end extending into the first mounting groove 131 and contacting the first limiting member 410. The positioning portion 422 is connected to the other end of the second limiting portion 421 and protrudes from the side wall of the second limiting portion 421. The positioning portion 422 is located outside the second mounting groove 132 and abuts against the upper core 100. For example, see... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the second limiting part 421 is in the shape of a thin sheet, and the positioning part 422 is connected to the top end of the second limiting part 421 and protrudes outward along the radial direction of the upper core 100. When the second limiting part 421 is inserted into the second mounting groove 132 until the positioning part 422 abuts against the connecting part 120 between the outer tube part 110 and the inner sleeve 130, the bottom end of the second limiting part 421 extends into the first mounting groove 131 and abuts against the first limiting member 410. Thus, by limiting the second limiting part 421 through the positioning part 422, the installation of the second limiting part 421 is realized, improving the convenience of installation and making the installation of the second limiting part 421 more stable.

[0056] In some embodiments, one end of the second limiting portion 421 that extends into the first mounting groove 131 is provided with a limiting notch 423, and the limiting notch 423 fits against the outer surface of the first limiting member 410. For example, see Figure 5As shown, the first limiting part 412 has a cylindrical structure, and the bottom end of the second limiting part 421 has a semi-circular limiting notch 423, so that the inner wall of the limiting notch 423 can fit tightly against the outer surface of the first limiting part 412. Therefore, when the first limiting part 412 moves upward, it will abut against the inner wall of the limiting notch 423, making the limiting effect on the first limiting part 412 more stable.

[0057] Continue reading Figure 5 As shown, in some embodiments, the limiting notch 423 is coaxially arranged with the first limiting member 410. Specifically, the central axis of the semi-circular limiting notch 423 is collinear with the central axis of the cylindrical first limiting part 412, so that the first limiting part 412 can move freely along the extension direction of the first mounting groove 131 without being blocked by the second limiting part 421. At the same time, the second limiting part 421 can form a stable limit on the first limiting part 412 through the limiting notch 423, further improving the stability of the core mechanism 10.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
