[0060] The core of the utility model is to disclose a liquid discharge device to solve the problem of liquid dripping, thereby improving the performance of the beverage machine and maintaining the quality of the beverage.

[0061] Another core of the utility model is to disclose a beverage machine including the above-mentioned liquid outlet device.

[0062] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0063] Combination Figure 1-Figure 14 The liquid discharge device disclosed in the embodiment of the utility model includes a discharge pipe 200, a check valve assembly 100 and a discharge driver. The discharge pipe 200 is used for discharge, and the check valve assembly 100 includes a check valve 110. The check valve 110 is arranged at the discharge end of the discharge pipe 200 and has a check surface 111 protruding in the direction of the discharge pipe 200, that is, in the opposite direction of the discharge direction. The check surface 111 is made of elastic material and has a discharge cutout for discharge. When the discharge is not in progress, the discharge cutout is closed and the check valve 110 is closed. When the discharge is in progress, the discharge cutout is opened and the check valve 110 is opened. The discharge driver is connected to the discharge pipe 200, and is used to drive the liquid discharge medium (liquid material) to discharge from the discharge pipe 200, and when the discharge is stopped, the inside of the discharge pipe 200 has a negative pressure.

[0064] When unloading, the unloading drive rotates forward to unload the unloading pipe 200, and the unloading medium enters the check surface 111 of the check valve 110 from the unloading pipe 200, and exerts pressure on the check surface 111, so that the check surface 111 is deformed, the unloading incision is opened, and the unloading medium can pass through the check valve 110 normally; when unloading is stopped, the unloading drive reverses to suck back the unloading medium and forms a negative pressure space in the unloading pipe 200 and then stops. In the absence of pressure exerted by the unloading medium, the check surface 111 can automatically reset, so that the unloading incision is automatically closed. Since the check surface 111 protrudes in the direction of the unloading pipe 200 and the unloading pipe 200 is in a negative pressure environment, that is, there is a pressure difference on both sides of the check surface 111, it can effectively support a certain amount of wall droplets, greatly reducing the occurrence of dripping of the unloading medium.

[0065] Compared with the prior art, the liquid discharge device disclosed in the utility model has a simple structure and low cost. By adding a check valve 110 to the discharge end of the discharge pipe 200, the problem of liquid dripping is effectively avoided. At the same time, the protruding setting of the check surface 111 in the direction of the discharge pipe 200 and the formation of a negative pressure space in the discharge pipe 200 effectively avoids the leakage of wall droplets, which can improve the performance of the beverage machine and ensure the quality and taste of the beverage.

[0066] It is understandable that the connection between the check valve assembly 100 and the feed pipe 200 is sealed to avoid leakage at the connection between the two parts, and to ensure the formation of a negative pressure space inside the feed pipe 200. The feed cutout on the check surface 111 can be in a straight line, a cross, or other shapes.

[0067] Combination Figure 2 The check valve 110 includes an annular mounting portion 112 for connecting with the feeding pipe 200, and a check surface 111 is arranged on the inner circle of the annular mounting portion 112. When the feeding pipe 200 is feeding, the check surface 111 is deformed along the feeding direction and the feeding cutout is opened. When the feeding pipe 200 stops feeding, the check surface 111 returns to the initial state.

[0068] Furthermore, when the non-return surface 111 is deformed to open the feed cutout, the feed cutout is located outside the annular mounting portion 112, that is, in a natural state, the non-return surface 111 is deformed to convexly move toward the side close to the feed pipe 200. When the liquid is discharged, the non-return surface 111 is deformed toward the side away from the feed pipe 200 by the pressure of the liquid, and the actual liquid discharge position is located outside the annular mounting portion 112 ( Fig.13 and Fig.14 The red dotted line portion in the middle) can effectively prevent residual liquid from being retained on the inner wall of the annular mounting portion 112 when the liquid is stopped, causing dripping and contamination of the liquid.

[0069] Combination Figure 2 and Fig.14 The annular mounting portion 112 has a liquid storage ring groove connected to the feeding pipe 200. When the feeding pipe 200 discharges materials, the liquid storage ring groove discharges materials synchronously from the feeding cutout. When the feeding pipe 200 stops discharging materials, the check surface 111 guides the wall-hanging liquid into the liquid storage ring groove for temporary storage to avoid dripping.

[0070] Specifically, the inner ring side wall of the liquid storage annular groove is connected to the check surface 111 as a connecting wall. When the material is discharged from the discharge pipe 200, the connecting wall conforms to the deformation of the check surface 111 and deforms synchronously in the discharge direction, thereby destroying the liquid storage annular groove and realizing the discharge of the material in the liquid storage annular groove. At the same time, the deformation of the connecting wall can also ensure that the discharge cutout can be located outside the annular mounting portion 112 during discharge, avoiding residual liquid from being retained on the inner wall of the annular mounting portion 112.

[0071] It is understandable that for liquids that are easy to stick to the wall, the thickness of the check surface 111 is set to be thicker, so that a greater force is required to open the feed cutout, thereby being able to effectively receive more liquid that sticks to the wall and reduce the occurrence of dripping. That is, the thickness of the check surface 111 is positively correlated with the degree of sticking to the wall of the feed medium, and the thickness of the connecting wall is also positively correlated with the degree of sticking to the wall of the feed medium.

[0072] In one embodiment, the thickness of the check surface 111 is between 0.15 mm and 0.35 mm, and the thickness of the rest of the check valve 110 is between 0.35 mm and 0.5 mm. The specific parameter settings are adjusted according to the output volume.

[0073] The above-mentioned check valve 110 can be an integrated structure made of elastic materials such as silicone, that is, the annular mounting portion 112 and the check surface 111 can be integrally formed by elastic materials. The check valve 110 made of elastic material itself has a certain sealing performance, which can reduce the occurrence of liquid dripping.

[0074] According to actual conditions, the number of the feeding tubes 200 on the beverage machine can be one or more, and at least one feeding tube 200 is provided with a check valve assembly 100 for feeding special liquid beverages (liquid beverages that are easy to hang on the wall). When the dispensing stops, the elasticity of the check surface 111 itself is used and the reversal of the feeding drive is synchronously coordinated to form a negative pressure inside the feeding tube 200, so that the check valve 110 is closed to achieve the effect of anti-drip, reduce the risk of beverage mixing, and improve the quality of the beverage. When the number of the feeding tubes 200 is multiple, the check valve assembly 100 can be multiple groups, and they are arranged one by one at the feeding end of each feeding tube 200, or the check valve assembly 100 can be set as an integrated component and have multiple check surfaces 111 corresponding one by one to the feeding tubes 200.

[0075] Specifically, in one embodiment, the check valve assembly 100 corresponds one-to-one to the discharge pipe 200, and the check valve assembly 100 includes a valve fixing seat 120 and an external fixing seat 130. The valve fixing seat 120 has a discharge channel and is sealed and connected to the discharge end of the discharge pipe 200 through a sealing member 121 (sealing gasket or sealing ring). The check valve 110 is arranged on the valve fixing seat 120, and the annular mounting portion 112 and the check surface 111 are both located in the discharge channel of the valve fixing seat 120. The external fixing seat 130 has a discharge channel. The first end of the external fixing seat 130 is connected to the discharge end of the discharge pipe 200, and the second end is used to press the check valve 110 onto the valve fixing seat 120. The valve fixing seat 120 is arranged in the discharge channel of the external fixing seat 130.

[0076] Combination Figure 2 The feeding end of the feeding tube 200 is provided with a feeding installation part 201 by welding or other means. During installation, the valve fixing seat 120 and the check valve 110 need to be assembled together first, and then the assembly of the valve fixing seat 120 and the check valve 110 is installed in the outer fixing seat 130 by tooling, and then the sealing member 121 is installed to form the check valve assembly 100, and finally the check valve assembly 100 is installed as a whole on the feeding installation part 201. The feeding end of the feeding tube 200 is used to be assembled with the feeding nozzle fixing plate of the beverage machine through connecting members 220 such as bolts and connecting columns to achieve fixation with the beverage machine body.

[0077] When a certain feeding driver (peristaltic pump) works, the liquid beverage in the liquid holding container is sequentially transported to the finished cup or shaker through the liquid suction pipeline, the pump tube, the feeding pipe 200 and the check valve 110. At this time, the check valve 110 opens the feeding incision through the pressure of the pump (liquid beverage). When the feeding amount reaches the set value, the feeding driver reverses to draw the liquid beverage in each pipeline back to the liquid holding container. At the moment when the feeding driver stops and reverses, the check valve 110 automatically resets and closes the feeding incision by its own elasticity. At the same time, the reversal of the feeding driver forms a negative pressure environment in the feeding pipe 200, so that the check valve 110 is closed more tightly. Even if the wall liquid remaining on the wall of the feeding pipe 200 gathers on the check valve 110 under the action of gravity, the force required to open the check valve 110 is much greater than the gravity of the residual liquid, and the liquid will not drip, thereby achieving an anti-drip effect, thereby improving the quality and taste of the beverage.

[0078] Among them, the material removal installation part 201 has a material removal channel, one end of the valve fixing seat 120 is located in the material removal channel of the material removal installation part 201, and an annular protrusion is provided on the outer peripheral wall of the valve fixing seat 120, and the annular protrusion and the end face of the installation part are sealed by a sealing member.

[0079] Combination Figure 2The outer ring of the annular mounting portion 112 of the check valve 110 has an annular mounting bevel on one end facing the valve fixing seat 120, and the valve fixing seat 120 has an annular matching bevel on one end facing the check valve 110. When the check valve 110 is installed on the valve fixing seat 120, the annular mounting bevel fits with the annular matching bevel to achieve positioning fit.

[0080] Combination Figure 2 The outer peripheral wall of the blanking installation part 201 is provided with an external thread, and the inner wall of the first end of the external fixing seat 130 is provided with an internal thread that can be threadedly connected with the external thread of the blanking installation part 201, corresponding to the screwing installation of the external fixing seat 130, combined with Figure 3-Figure 5 , anti-slip protrusions may be provided on the outer wall of the outer fixing seat 130 .

[0081] In order to ensure the reliability of the installation position of the check valve 110, the inner ring of the second end of the external fixing seat 130 has an undercut structure that can abut against the end face of the annular mounting portion 112 of the check valve 110. During assembly, the undercut structure remains in contact with the check valve 110, thereby preventing the check valve 110 from tilting or wrinkling, and also preventing the check valve 110 from falling off and deforming (except for the check surface 111) when liquid flows out.

[0082] In another embodiment, there are multiple discharge pipes 200, and they are all arranged on the discharge base 210 to form a discharge pipe assembly. The check valve 110 is an integrated check valve component with multiple check surfaces 111, and each check surface 111 corresponds to the discharge pipe 200 one by one. After the liquid flows out of each discharge pipe 200, it enters different check surfaces 111 to prevent dripping.

[0083] The discharge pipe 200 and the discharge base 210 can be connected by welding or the like. The check valve assembly 100 also includes an integrated fixing seat 160, which is used to install the above-mentioned integrated check valve component on the discharge base 210. When the integrated check valve component is made of elastic material, the integrated check valve component can be pressed by the mounting seat and the discharge pipe 200 to ensure a sealed connection between the three.

[0084] In order to facilitate the installation and positioning between the above-mentioned down pipe assembly and the integrated check valve component, a guide portion is provided on one of the two, and a limiting portion for cooperating with the guide portion is provided on the other to facilitate the positioning and installation of the down pipe assembly and the integrated check valve component.

[0085] Specifically, the guide portion can be a plurality of guide posts arranged at circumferential intervals around the integrated check valve component, and the limiting portion is a limiting hole corresponding to the guide posts one by one and for the guide posts to be embedded in, thereby achieving positioning and guiding of the two.

[0086] Furthermore, one end of the guide portion used for embedding in the limiting hole can be set as a tapered guide structure with a gradually reduced size, so as to facilitate embedding and installation in the limiting hole.

[0087] The guide column mentioned above can also be replaced by a guide block, a guide protrusion, etc., and the shape of the limiting hole corresponds to it.

[0088] Combination Fig.12 and Fig.13 In order to facilitate the corresponding installation of each discharge pipe 200 and the check valve 110, a plurality of guide cone holes for the discharge ends of the discharge pipes 200 to be embedded one by one are provided on the integrated check valve component, and the check surface 111 is provided in the guide cone hole. The discharge end of each discharge pipe 200 can be assembled with the check surface 111 through the guidance of the guide cone hole. The discharge end of the corresponding discharge pipe 200 can also be provided with a tapered conical structure, which is convenient for positioning and installation with the guide cone hole.

[0089] Combination Fig.13 The guide cone hole and the annular mounting portion 112 may be an integrated structure, or the guide cone hole and the annular mounting portion 112 may be a split structure and the two are connected.

[0090] In a specific embodiment disclosed in the present utility model, the above-mentioned integrated check valve component includes an integrated valve body 150 and an insert 140. The integrated valve body 150 has a plurality of check surfaces 111 and is provided with an avoidance hole.

The guide portion is arranged on the insert 140 and passes through the avoidance hole to cooperate with the limiting portion. The integrated fixing seat 160 presses the integrated valve body 150 and the insert 140 together to install them on the discharge pipe assembly.

[0091] The insert 140 mentioned above may be a rubber-encapsulated insert to further improve the sealing performance and avoid liquid mixing.

[0092] In order to realize the positioning and installation of the integrated valve body 150 and the insert 140 , a positioning and installation hole is provided on the integrated valve body 150 , and a positioning and installation protrusion for embedding in the positioning and installation hole is provided on the insert 140 .
