Description

Technical Field

[0001] This utility model relates to the technical field of ice-making equipment, and in particular to a sealing and leak-proof structure for the discharge port of a snow melting machine. Background Technology

[0002] A slush machine, also known as a slush machine, has an evaporator and a cylinder for making ice. Inside the cylinder is a stirring component that crushes the ice into slush. The slush machine has a motor that drives the stirring component to rotate. The evaporator is located inside the cylinder, and it exchanges heat with the liquid in the cylinder, causing the liquid in the cylinder to form ice. The motor drives the stirring component to rotate, causing the ice to form slush. When the cylinder outputs the slush into a drinking container, the liquid in the drinking container is mixed with the slush to make a cold drink.

[0003] In existing slush machines, a discharge nozzle is usually installed at the outlet of the material cylinder to guide the output slush and allow it to smoothly enter the receiving cup. However, since there is usually a gap between the nozzle and the material cylinder, a small amount of melted slush seeps into the gap during the output process, causing leakage and greatly reducing the user experience. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, this utility model provides a sealing and leak-proof structure for the discharge port of a snow melting machine.

[0005] The above-mentioned problems of this utility model are solved by the following technical solution:

[0006] A sealing and leak-proof structure for the discharge port of a snow melting machine includes a material cylinder installed on the snow melting machine, wherein the material cylinder is provided with a material inlet and a material outlet;

[0007] A discharge nozzle assembly is installed at the discharge port. The discharge nozzle assembly has an inlet and an outlet, and the inlet is connected to the discharge port of the material cylinder.

[0008] The discharge nozzle assembly is provided with a first sealing structure and a second sealing structure at the inlet and outlet, respectively, to seal the discharge channel of the discharge nozzle assembly.

[0009] A further provision of the above technical solution is that the first sealing structure is a first sealing ring covering the inlet edge of the discharge nozzle assembly.

[0010] A further feature of the above technical solution is that the main body of the first sealing ring has an L-shaped cross-section and a mating protrusion is provided on the upper end face.

[0011] By adopting the above solution, the L-shaped first sealing ring fits the wavy edge of the material cylinder outlet through the edge wrapping design, adapting to the arc or irregular contact surfaces of different components, and ensuring the completeness of the seal.

[0012] A further provision of the above technical solution is that the discharge nozzle assembly includes a discharge nozzle body, and the inlet and outlet are through holes located on the upper and lower sides of the discharge nozzle body;

[0013] The second sealing structure is a second sealing ring that covers the edge of the outlet.

[0014] A further provision of the above technical solution is as follows: a discharge nozzle is fixed at the lower part of the discharge nozzle body, the discharge nozzle is provided with an inclined discharge pipe, the discharge pipe is connected to the outlet, and the second sealing ring seals the discharge pipe and the edge of the outlet.

[0015] A further provision of the above technical solution is that the cross-section of the second sealing ring is Z-shaped, including a sealing platform and a first sealing shoulder and a second sealing shoulder vertically disposed at both ends of the sealing platform;

[0016] The first sealing shoulder extends upward to support the discharge nozzle body, and the second sealing shoulder extends downward to support the discharge nozzle.

[0017] By adopting the above technical solution, the sealing platform, first sealing shoulder and second sealing shoulder of the Z-type second sealing ring respectively support the discharge nozzle body and the discharge nozzle, making up for the gap difference between the lower arc surface of the discharge nozzle body and the discharge nozzle during assembly, and enhancing the stability of the seal.

[0018] A further provision of the above technical solution is that a pad is provided around the feeding tube on the feeding nozzle, and the sealing platform is placed on the pad.

[0019] A further provision of the above technical solution is as follows: the inside of the discharge nozzle body is provided with a channel chamber communicating with the inlet and outlet, and a discharge valve is arranged in the channel chamber. The discharge valve is driven by a handle so that it has a discharge state that connects the inlet and outlet in the discharge nozzle body, and a closed state that isolates the inlet and outlet.

[0020] By adopting the above technical solution, the discharge nozzle body has a built-in discharge valve that can be driven by a handle, which can control the discharge status (through or interruption) and further reduce the risk of leakage when closed in conjunction with the sealing structure, thus achieving the dual function of "sealing + control".

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a first sealing ring at the inlet of the discharge nozzle assembly and a second sealing ring at the outlet, the double sealing structure covers the key assembly gap of the discharge channel, preventing the liquid from melting ice from seeping into the gap and causing leakage, thus forming a full-process seal for the discharge channel; the L-shaped sealing ring at the inlet covers the edge of the discharge port of the material cylinder, preventing the liquid from melting ice from seeping into the assembly gap between the material cylinder and the discharge nozzle; the Z-shaped sealing ring at the outlet, through the design of "sealing platform + double sealing shoulder", adapts to the assembly gap at different positions, ensuring a tight fit between the discharge nozzle body and the discharge nozzle, and preventing ice from seeping out.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] like Figure 1-5As shown in the figure, this embodiment discloses a sealing and leak-proof structure for the outlet of a snow melting machine.

[0034] A sealing and leak-proof structure for the outlet of a snow melting machine includes a material cylinder 100 installed on the snow melting machine, wherein the material cylinder 100 is provided with an inlet 101 and an outlet 102;

[0035] A discharge nozzle assembly 200 is installed at the discharge port 102. The discharge nozzle assembly 200 is provided with an inlet 211 and an outlet 212, and the inlet 211 is connected to the discharge port 102 of the material cylinder 100.

[0036] The discharge nozzle assembly 200 is provided with a first sealing structure and a second sealing structure at the inlet 211 and outlet 212, respectively, to seal the discharge channel of the discharge nozzle assembly 200.

[0037] The above is the basic scheme of this embodiment.

[0038] Specific reference Figure 1 and Figure 2 As shown, the material cylinder 100 has an opening on one side for connecting to the snow melting machine. The evaporator of the snow melting machine is inserted into the material cylinder 100 through this opening, and ice slush is made in the material cylinder 100 for discharge.

[0039] The feed inlet 101 is located at the upper end of the material cylinder 100, and the discharge outlet 102 is located at the lower end of the material cylinder 100. The feed inlet 101 is located on the side close to the opening of the material cylinder 100, and the discharge outlet 102 is located on the side away from the opening of the material cylinder 100. Liquid raw materials are put into the feed inlet 101. The liquid raw materials form ice slush under the action of the evaporator, and are scraped off by the scraper and pushed towards the discharge outlet 102. The material is discharged from the discharge outlet 102.

[0040] The discharge port 102 is a hole set on the material cylinder 100. When the ice slush is discharged through the discharge port 102, it will splash in the hole area, which will cause inaccurate discharge. Therefore, a discharge nozzle assembly 200 is provided in the discharge port 102 to guide the ice slush and avoid splashing during discharge.

[0041] In this embodiment, the discharge nozzle assembly 200 is provided with an inlet 211 and an outlet 212. The inlet 211 is connected to the discharge port 102 of the material cylinder 100. The ice slush output from the discharge port 102 enters the interior of the discharge nozzle assembly 200 through the inlet 211 and is output from the outlet 212 under the guidance of the discharge nozzle assembly 200.

[0042] To ensure sealing during the discharge process, in this embodiment, a first sealing structure is provided between the inlet 211 of the discharge nozzle assembly 200 and the outlet 102 of the material cylinder 100. This sealing structure seals the assembly parts of the discharge nozzle assembly 200 and the material cylinder 100, ensuring that the ice slush does not leak out during the process of entering the discharge nozzle assembly 200 from the material cylinder 100.

[0043] Meanwhile, in this embodiment, a discharge nozzle 300 is provided at the outlet 212 of the discharge nozzle assembly 200. Therefore, a second sealing structure is provided between the discharge nozzle assembly 200 and the discharge nozzle 300. This second sealing structure seals the assembly part between the discharge nozzle assembly 200 and the discharge nozzle 300, ensuring that the ice slush will not leak when it is output from the outlet 212 of the discharge nozzle assembly 200.

[0044] Based on the above settings, in this embodiment, by sealing the assembly parts between each component, the channel is sealed during the process of ice slush being output from the material cylinder 100, thus avoiding leakage during the discharge process.

[0045] Specifically, in this embodiment, the first sealing structure is a first sealing ring 400 that covers the edge of the inlet 211 of the discharge nozzle assembly 200.

[0046] Specific reference Figure 3 and Figure 4 As shown, the discharge nozzle is a hole located at the lower end of the material cylinder 100. Due to the cylindrical structure of the material cylinder 100, the edge of the discharge nozzle is a wavy annular structure. To ensure a sealing effect, the first sealing ring 400 in this device wraps around the edge of the inlet 101, and the upper end of the wrapping extends outward to the upper end of the hole, thus forming a structure that covers the inner wall of the hole.

[0047] Therefore, in this embodiment, the main body cross-section of the first sealing ring 400 is L-shaped, and a mating protrusion 410 is provided on the upper end surface.

[0048] Specific reference Figure 4 As shown, the first sealing ring 400 includes a vertical wrapping ring abutting against the end face of the nozzle body 210, and a horizontal ring formed on the upper end of the wrapping ring. The wrapping ring wraps around the outer wall of the outlet 102, and its lower end extends into the outlet body 210, thereby sealing the gap between the outlet 102 and the outlet body 210. At the same time, the horizontal ring is located on the upper end face of the outlet body 210, clamping between the outlet body 210 and the material cylinder 100. Furthermore, an annular mating protrusion 410 is provided on the upper end face of the horizontal ring. The mating protrusion 410 forms an interference fit with the lower end face of the material cylinder 100, further ensuring the sealed connection between the material cylinder 100 and the outlet body 210.

[0049] In other embodiments, the first sealing ring 400 may also be configured as a C-shaped structure, with the edge of the hole inserted into the slot of the first sealing ring 400.

[0050] In this embodiment, the discharge nozzle assembly 200 includes a discharge nozzle body 210, and the inlet 211 and outlet 212 are through holes provided on the upper and lower sides of the discharge nozzle body 210.

[0051] The second sealing structure is a second sealing ring 500 that covers the edge of the outlet 212.

[0052] The outlet 212 of the discharge nozzle body 210 is also set as an opening. During the discharge process, ice shavings will splash. Therefore, in this embodiment, a discharge nozzle 300 is fixed at the lower part of the discharge nozzle body 210. The discharge nozzle 300 is provided with an inclined discharge pipe 310. The discharge pipe 310 is connected to the outlet 212. The second sealing ring 500 seals the edges of the discharge pipe 310 and the outlet 212.

[0053] Preferably, in this embodiment, a guide ring 110 extends downward from the edge of the discharge port 102 of the material cylinder 100, and the first sealing ring 400 is disposed on the outer ring of the guide ring 110.

[0054] Specific reference Figure 3 and Figure 5 As shown, the lower end face of the discharge nozzle body 210 is an arc-shaped surface, that is, the edge of the outlet 212 is an arc-shaped structure. When it is assembled with the discharge nozzle 300, it is impossible to assemble it without gaps. Therefore, in this embodiment, the second sealing ring 500 is set between the discharge nozzle body and the discharge nozzle 300 to form an annular seal around the outlet 212 between the discharge nozzle body 210 and the discharge nozzle 300, so as to ensure the sealing of the discharge channel.

[0055] Specifically, the cross-section of the second sealing ring is Z-shaped, including a sealing platform 510 and a first sealing shoulder 520 and a second sealing shoulder 530 vertically disposed at both ends of the sealing platform 510;

[0056] The first sealing shoulder 520 extends upward to support the discharge nozzle body 210, and the second sealing shoulder 530 extends downward to support the discharge nozzle 300.

[0057] Due to limitations in production technology, the gaps between the discharge nozzle and the discharge nozzle 300 at different locations are inconsistent. Therefore, in this embodiment, the second sealing ring is configured as multiple sealing parts. The sealing platform 510 is the main body, and the first sealing shoulder 520 extends upward from the sealing platform 510 to seal the gap between the sealing platform 510 and the discharge nozzle. The second sealing element extends downward from the sealing platform 510 to seal the gap between the sealing platform 510 and the discharge nozzle 300, thereby forming an annular sealing wall between the discharge nozzle and the discharge nozzle 300. The upper and lower ends of the sealing wall are respectively press-fitted with the sealing nozzle and the discharge nozzle 300 to form a sealing channel.

[0058] To ensure the stability of the second sealing ring, a pad is provided on the discharge nozzle 300 around the discharge tube 310, and the sealing platform 510 is placed on the pad.

[0059] Specific reference Figure 3 As shown, the upper end of the feeding tube 310 of the feeding nozzle 300 is set higher than the pad, and the pad is an annular plane surrounding the feeding tube 310.

[0060] In this embodiment, the nozzle body 210 has a channel chamber inside that communicates with the inlet 211 and the outlet 212. A discharge valve 220 is arranged inside the channel chamber. The discharge valve 220 is driven by a handle 230 so that it has a discharge state that connects the inlet 211 and the outlet 212 and a closed state that isolates the inlet 211 and the outlet 212 within the nozzle body 210.

[0061] Rotating handle 230 causes discharge valve 220 to rotate. When the two ends of the channel on discharge valve 220 are connected to inlet 211 and outlet 212 respectively, the slush entering inlet 211 can be discharged from outlet 212 along the channel on discharge valve 220. At this time, discharge valve 220 is in the discharge state. When handle 230 drives discharge valve 220 to the closed state, the channel on discharge valve 220 and inlet 211 on discharge nozzle body 210 are misaligned. That is, inlet 211 cannot be connected to the channel of discharge valve 220, so slush cannot be discharged.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
