Description

Technical Field

[0001] The utility model relates to the technical field of dispensers, and particularly relates to a mixer for a mixing valve of a dispenser and a mixing valve of a dispenser including the same. Background Art

[0002] At present, when using concentrated raw materials with poor solubility (such as concentrated liquid containing fiber components), there is a phenomenon that the concentrated liquid and drinking water are not fully mixed in the mixing valve of the existing dispensers on the market. This insufficient mixing includes stratification of the concentrated liquid and drinking water, sedimentation of the concentrated liquid at the bottom, uneven taste of the beverage, and large changes in taste sugar content. This brings an unpleasant experience to consumers and also causes many troubles to operators and raw material suppliers. There is an urgent need to solve this problem in the industry. Summary of the Utility Model

[0003] In order to solve the above problems, it would be beneficial for the utility model to provide a mixer for a mixing valve of a dispenser that can fully mix various concentrated liquids and drinking water, and a mixing valve of a dispenser including the same.

[0004] To achieve the above object, according to one aspect of the utility model, there is provided a mixer for a mixing valve of a dispenser, which is characterized in that it is adapted to be embedded and installed in the horizontal water inlet part of the mixing valve of the dispenser. The mixer includes a mixing and stirring part and a water outlet cylindrical part arranged front and back. Among them, the mixing and stirring part includes a central shaft coaxially connected to the water outlet cylindrical part, and multiple layers of mixing and stirring teeth axially spaced apart on the central shaft; the water outlet cylindrical part is configured as a hollow cylinder with a closed front end, an open rear end, and a central cavity; and among them, the water outlet cylindrical part is provided with a plurality of water outlet holes on its outer circumferential surface, and the plurality of water outlet holes are arranged in a spiral pattern along the outer circumferential surface of the water outlet cylindrical part and are all communicated with the central cavity, so as to form a spiral water flow to drive the mixer to rotate in the horizontal water inlet part of the mixing valve of the dispenser.

[0005] In the utility model, through the structural setting of the water outlet cylindrical part itself, when the end of the horizontal water inlet part of the mixing valve of the dispenser is inserted with a mixing valve connecting pipe, the front end of the mixing valve connecting pipe is aligned with and contacts the water outlet cylindrical part of the mixer in the horizontal water inlet part, so that the drinking water from the mixing valve connecting pipe can enter the central cavity of the mixer and is discharged through the spirally arranged water outlet holes to form a spiral water flow on the outer circumferential surface of the water outlet cylindrical part. Under the impact of the water flow, the entire mixer starts to rotate in the horizontal water inlet part, and the drinking water and the concentrated liquid entering the mixing valve are fully mixed under the mixing and stirring of the multiple layers of mixing and stirring teeth on the mixing and stirring part. Especially for concentrated liquids with poor solubility, the stratification phenomenon of the beverage can be better eliminated, and the taste is stable and uniform.

[0006] Further, the opening position of the water outlet hole is offset relative to the axis line of the water outlet cylindrical part, and the water outlet hole is arranged to be tangent to the cavity wall of the central cavity.

[0007] Through the structural arrangement that the position of the water outlet hole is offset relative to the axis line and is tangent to the cavity wall of the central cavity, the water flow velocity flowing out from the central cavity through the water outlet hole is further increased, and thus the whole mixer can rotate better under the rapid push of the water flow.

[0008] Still further, each layer of mixing and stirring teeth is configured as petal-shaped mixing and stirring teeth and includes a plurality of petal teeth circumferentially and uniformly distributed around the central axis, and the petal teeth of two adjacent layers of mixing and stirring teeth are arranged in a circumferential dislocation.

[0009] Through the above structural arrangement, a more powerful mixing and stirring action can be implemented, making the concentrated liquid and the drinking water mix more fully.

[0010] Even further, the petal teeth of two adjacent layers of mixing and stirring teeth are arranged in a circumferential dislocation of 45°.

[0011] Through this dislocation arrangement, the mixing and stirring strength can be further enhanced.

[0012] Even further, the multi-layer mixing and stirring teeth are three-layer mixing and stirring teeth.

[0013] Even further, each layer of mixing and stirring teeth includes four petal teeth.

[0014] Even further, the plurality of water outlet holes are four water outlet holes, and every two adjacent water outlet holes are arranged at a circumferential interval of 90°.

[0015] Through the relatively sparse water outlet holes circumferentially and uniformly distributed, the water flow velocity of the water outlet can be further greatly increased, and the mixing and stirring strength can be enhanced.

[0016] According to another aspect of the present invention, there is provided a mixing valve for a ready-to-drink machine, which includes the mixer for the mixing valve of the ready-to-drink machine as described above.

[0017] In the present invention, by adding the above mixer and by virtue of the structural design of its water outlet holes and multi-layer mixing and stirring teeth, under the push of the water flow, the mixer can rotate in the horizontal water inlet part of the mixing valve of the ready-to-drink machine, accelerating the mixing between the concentrated liquid and the drinking water. The mixed liquid formed after mixing can enter the vertical liquid outlet part of the mixing valve of the ready-to-drink machine along the periphery of the mixer and flow out from it into the cup, realizing that the drink is not stratified, the taste is uniform, and the sugar content is stable.

[0018] By referring to the embodiments described below, these aspects and other aspects of the present invention will be more clearly explained. Brief Description of the Drawings

The mixer 100 includes a rear-arranged water outlet cylindrical part 1 and a front-arranged mixing and stirring part 3. Among them, the mixing and stirring part 3 includes a central shaft 30 coaxially connected to the water outlet cylindrical part 1, and three layers of mixing and stirring teeth 32 axially spaced apart on the central shaft 30; the water outlet cylindrical part 1 is configured as a hollow cylinder with an open rear end 11, a closed front end 13, and a central cavity 10. Among them, four water outlet holes 5 are provided on the outer circumferential surface 12 of the water outlet cylindrical part 1, and these water outlet holes 5 are arranged in a spiral pattern along the outer circumferential surface 12 of the water outlet cylindrical part 1. Each two adjacent water outlet holes 5 are circumferentially spaced 90°, and all communicate with the central cavity 10, so as to be able to form a spiral water flow to drive the mixer 100 to rotate in the horizontal water inlet part 301 of the instant dispenser mixing valve 300. As Figure 4 shown, for clarity, the spiral arrangement of the water outlet holes 5 is represented by the spiral L1.

[0032] As Figure 2 and Figure 5 clearly shown, in this embodiment, the opening positions of the water outlet holes 5 are offset relative to the axis X of the water outlet cylindrical part 1, and the water outlet holes 5 are arranged to be tangent to the cavity wall 14 of the central cavity 10.

[0033] As Figure 1 and Figure 6 clearly shown, in this embodiment, each layer of the mixing and stirring teeth 32 is configured as a petal-shaped mixing and stirring tooth, and includes four petal teeth 320 circumferentially evenly distributed around the central shaft 30. Moreover, the petal teeth 320 of the adjacent two layers of mixing and stirring teeth 32 are circumferentially misaligned. In this embodiment, the circumferential misalignment is 45°.

[0034] It should be noted that although in this embodiment, a total of three layers of mixing and stirring teeth 32 are provided, each layer of mixing and stirring teeth 32 includes four petal teeth 320, and in addition, a total of four water outlet holes 5 are provided, it should be understood that in other embodiments, the number of water outlet holes 5, the number of layers of mixing and stirring teeth 32, and the number of petal teeth 320 provided in each layer of mixing and stirring teeth 32 can all be adjusted according to actual needs.

[0035] According to another aspect of the present invention, there is provided a fresh drink dispenser mixing valve 300 as shown in Figure 7 and Figure 8 , which includes a mixer 100.

[0036] Next, with reference to Figure 7 and Figure 8 and in combination with Figures 1 to 6 , the application process of the mixer 100 in the fresh drink dispenser mixing valve 300 will be introduced:

[0037] As shown in Figure 7 and Figure 8 , the fresh drink dispenser mixing valve 300 includes a horizontal water inlet part 301, a vertical liquid outlet part 303 and a concentrated liquid inlet part 305. Among them, a mixing valve connecting pipe 200 is inserted at the rear end of the horizontal water inlet part 301, and the pipe hole 210 of the mixing valve connecting pipe 200 is opposite to and communicated with the central cavity 10 of the mixer 100, so that the drinking water from the mixing valve connecting pipe 200 (as shown by the rightmost arrow in Figure 8 ) is sent into the central cavity 10; the concentrated liquid inlet part 305 is connected to the horizontal water inlet part 301 and has a concentrated liquid inlet 315, so that concentrated liquid such as various fruit pulp or vegetable juice concentrates enters the horizontal water inlet part 301 of the fresh drink dispenser mixing valve 300 through the concentrated liquid inlet 315;

[0038] The drinking water that enters the central cavity 10 of the mixer 100 through the pipe hole 210 of the mixing valve connecting pipe 200 then tangentially flows out through the water outlet holes 5 on the water outlet cylindrical part 1 of the mixer 100, so that the mixer 100 rotates under the impact of the water flow. The spiral water flow formed by the drinking water flowing along the path shown by the spiral L1 on the outer circumferential surface 12 of the cylindrical body 1 after being thrown out through the water outlet holes 5 further rapidly promotes the rotation of the mixer 100;

[0039] With the rotation of the mixer 100 and the stirring performed by the multi-row stirring and guiding teeth 3, the concentrated liquid and the drinking water are fully stirred and mixed, and the formed mixed liquid flows out from the vertical liquid outlet part 303 of the fresh drink dispenser mixing valve 300 and is poured into a cup, realizing that the drink is not stratified, has a uniform taste, and a stable sugar content.

[0040] It should be understood that in this embodiment, an O-ring seal 201 is provided on the mixing valve connecting pipe 200, so that when the mixing valve connecting pipe 200 is inserted into the horizontal water inlet part 301, the O-ring seal 201 plays a sealing role.

[0041] In addition, it should be noted that although the front end of the mixer connecting pipe 200 abuts against the rear end 11 of the mixer 100 when it is installed on the ready-mix machine mixing valve 300, the mixer 100 is still in clearance fit within the horizontal water inlet part 301 of the ready-mix machine mixing valve 300, without preventing it from rotating under the impact of water flow.

[0042] The technical content and features of the present utility model have been disclosed above. However, it can be understood that under the creative concept of the present utility model, those skilled in the art can make various changes and improvements to the above structure, including combinations of the technical features separately disclosed or claimed here, and other combinations that obviously include these features.
