Description

Technical Field

[0001] This utility model relates to the field of beverage preparation equipment technology, and more specifically to a pipeline quick switching device and a beverage machine. Background Technology

[0002] Currently, beverage machines on the market primarily use two methods for pipe switching during pipe cleaning: The first method uses a traditional T-joint for channel switching, as shown in the diagram. Figure 1 As shown, this method can only switch between the feed pipeline A-B1 and the cleaning pipeline A-C1, but cannot connect A-B1-C1. Therefore, the B2 section of the pipeline cannot be cleaned, resulting in incomplete cleaning. The second method involves two independent channels, cleaning channel E2 and discharge channel E1, as shown... Figure 2 As shown, when it is necessary to switch from the discharge channel E1 to the cleaning channel E2, it is necessary to manually connect the two channels with an external pipeline D2 (the D2 pipeline can be shared with the raw material pipeline D1, or it can be a separate new pipeline). However, this switching method is troublesome to operate, and the numerous external pipelines also affect the overall aesthetics of the equipment.

[0003] To overcome the shortcomings of the aforementioned pipeline switching methods, some products have improved the pipeline switching structure. For example, Chinese Patent No. CN211833975U discloses a pipeline flow and automatic cleaning device for a beverage machine, including first and second one-way check valves. The inlet end of the first one-way check valve is connected to a beverage storage device via a pipeline, and the outlet end of the second one-way check valve is connected to the first port of a three-way valve via a pipeline. The third port of the three-way valve is connected to a processing device with a pre-connected water circuit inside the beverage machine. The inlet end of the first one-way check valve is connected to the second port of the three-way valve via a pipeline. This allows for multi-pipeline flow in the beverage machine and automatic cleaning of the internal one-way check valves. However, the above technology requires two one-way check valves and one three-way valve to achieve this, resulting in more components, higher manufacturing costs, and a complex structure that is inconvenient for later maintenance and replacement. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a pipeline quick switching device and a beverage machine, which can easily and quickly switch between the dispensing state and the cleaning state, and the cleaning is thorough and the structure is simple.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pipeline quick switching device, including a cleaning cover, a feed connector and a tee fitting;

[0006] The feed connector has a liquid inlet; the tee has an inner cavity, a liquid outlet, and a cleaning port, with the liquid outlet and cleaning port respectively connected to the inner cavity.

[0007] When the feed connector is fully installed in the inner cavity of the tee, the inlet and outlet are connected, and the feed connector completely blocks the connection between the cleaning port and the inner cavity, and the pipeline quick switching device is in the discharge state.

[0008] After the feed connector is removed from the tee, the cleaning cover can be installed on the tee to seal the inner cavity of the tee, connecting the liquid outlet and the cleaning port, and the pipeline quick switching device is in the cleaning state.

[0009] This technical solution provides a pipeline quick switching device that can switch between discharge and cleaning states through a cleaning cover and feed connector that can be easily and quickly disassembled. This avoids inadequate pipeline cleaning and eliminates the need for numerous external pipelines in multi-channel systems, which affects the overall aesthetics of the equipment. It also reduces the amount of pipeline used and lowers the cost of replacing pipelines during maintenance. In addition, after the feed connector is installed, blocking the connection between the inner cavity and the cleaning port can prevent insects from entering the cleaning pipeline through the cleaning port, thus avoiding pipeline contamination.

[0010] In a preferred embodiment, a first gasket is provided inside the cleaning cover;

[0011] When the cleaning cover is installed on the tee, the first gasket is located between the cleaning cover and the tee to provide a seal.

[0012] In a preferred embodiment, the outer peripheral wall of the cleaning cover is provided with multiple ribs to facilitate the rotation and installation of the cleaning cover.

[0013] In a preferred embodiment, when the feed connector is fully installed in the inner cavity of the tee, a second gasket is provided between the feed connector and the tee to ensure a sealing effect.

[0014] In a preferred embodiment, the feed connector is installed in the inner cavity of the tee by a rotating snap fastener; the feed connector is provided with a rotating handle with multiple protruding ridges to facilitate manual selection of the feed connector by the user.

[0015] In a preferred embodiment, a flexible connector is also included, with one end connected to the cleaning cover and the other end connected to the tee.

[0016] In this technology, the cleaning cover is connected to the tee fitting via a flexible connector. When the pipeline quick switching device is in the discharge state, although the cleaning cover is not installed on the tee fitting, it is still connected to the tee fitting, making it convenient to use at any time when switching pipelines and less likely to be lost.

[0017] In a preferred technical solution, the flexible connector is a hanging rope, elastic rope, or spring, which is low in cost and readily available.

[0018] In a preferred embodiment, the outer peripheral wall of the tee fitting is provided with at least two locking positions for fixing the pipeline quick switching device to the main equipment.

[0019] In a preferred embodiment, the cleaning port is located at the lowest point of the inner cavity of the tee fitting, which facilitates the drainage of residual liquid and helps prevent liquid accumulation in the main equipment pipeline.

[0020] A beverage machine includes a pipeline quick switching device as described in any of the above technical solutions.

[0021] The beverage machine in this technology uses the aforementioned quick-switching pipeline device, which can conveniently and quickly switch between the dispensing pipeline and the cleaning pipeline, and the cleaning is thorough and easy to maintain.

[0022] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are:

[0023] This utility model provides a quick pipeline switching device that can switch between discharge and cleaning states through a cleaning cover and a feed connector that can be easily and quickly disassembled. This not only avoids inadequate pipeline cleaning, but also avoids the need for numerous external pipelines in multi-channel systems, which affects the overall aesthetics of the equipment. It also reduces the amount of pipeline used and lowers the cost of replacing pipelines during maintenance. In addition, after the feed connector is installed, blocking the connection between the inner cavity and the cleaning port can prevent insects from entering the cleaning pipeline through the cleaning port, thus avoiding contamination of the pipeline.

[0024] A beverage machine employs the aforementioned quick-switching pipeline device, which enables convenient and rapid switching between the dispensing pipeline and the cleaning pipeline, ensuring thorough cleaning and easy maintenance.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] In the description of this utility model, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] Reference Figure 3-9This invention describes a pipeline quick switching device and a beverage machine according to an embodiment of the present invention. The pipeline quick switching device can be applied to a beverage machine.

[0040] In one embodiment, such as Figure 3-9 As shown, a pipeline quick switching device includes a cleaning cover 1, a feed connector 2, and a tee fitting 3;

[0041] The feed connector 2 has a liquid inlet 21; the three-way fitting 3 has an inner cavity 30, a liquid outlet 31 and a cleaning port 32, with the liquid outlet 31 and the cleaning port 32 respectively connected to the inner cavity 30.

[0042] When the feed connector 2 is fully installed in the inner cavity 30 of the tee 3, the liquid inlet 21 is connected to the liquid outlet 31, and the feed connector 2 completely blocks the connection between the cleaning port 32 and the inner cavity 30, and the pipeline quick switching device is in the discharge state.

[0043] After the feed connector 2 is removed from the tee 3, the cleaning cover 1 can be installed on the tee 3 to seal the inner cavity 30 of the tee 3, and the liquid outlet 31 and the cleaning port 32 are connected, and the pipeline quick switching device is in the cleaning state.

[0044] The liquid inlet 21 is used to connect to the material source, the liquid outlet 31 is used to connect to the liquid outlet pipeline of the main equipment, and the cleaning port 32 is used to connect to the cleaning pipeline of the main equipment; the main equipment can be a beverage machine.

[0045] Specifically, the feed connector 2 can be installed in the inner cavity 30 of the tee 3 by rotating the snap fastener, and the cleaning cover 1 can be installed at one end of the opening of the tee 3 by rotating the snap fastener or by threaded connection.

[0046] The working principle of the above-mentioned pipeline quick switching device is as follows: When the pipeline quick switching device is in normal working condition (discharge state), the liquid inlet 21 of the feed connector 2 and the liquid outlet 31 of the tee 3 are connected, and the bottom of the feed connector 2 completely blocks the connection between the cleaning port 32 and the inner cavity 30, so that the liquid outlet 31 and the cleaning port 32 are not connected, and the raw material flows as follows. Figure 6 As shown by the middle arrow, the raw material enters from the inlet 21 and flows out from the outlet 31. When the pipeline quick switching device is in the discharge state, the cleaning cover 1 is not installed on the tee 3, but can be suspended on the tee 3 by a hanging rope or other connecting structure (such as a spring or elastic rope) so that it can be taken out at any time and is not easy to fall off or be lost.

[0047] To switch from the discharge state to the cleaning state, simply rotate and remove the feed connector 2, then rotate and tighten the cleaning cover 1 onto the tee fitting 3 to complete the state switch; at this time, the liquid outlet 31 and the cleaning port 32 are connected, and the cleaning liquid flows as follows: Figure 9As shown by the middle arrow, the cleaning liquid enters from the cleaning port 32, fills the inner cavity 30 of the tee 3, and then flows through the outlet 31 to the outlet pipeline of the main equipment.

[0048] To switch from cleaning mode to discharge mode, simply loosen the cleaning cover 1 manually and then manually tighten the feed connector 2 onto the tee fitting 3 to complete the switch.

[0049] This embodiment provides a quick pipeline switching device that can switch between discharge and cleaning states through a cleaning cover 1 and a feed connector 2 that can be easily and quickly installed and removed. This not only avoids inadequate pipeline cleaning, but also avoids the need for numerous external pipelines in multi-channel systems, which affects the overall aesthetics of the equipment. It also reduces the amount of pipeline used and lowers the cost of replacing pipelines during maintenance. In addition, after the feed connector 2 is installed, it blocks the connection between the inner cavity 30 and the cleaning port 32, which can prevent insects from entering the cleaning pipeline through the cleaning port 32 and avoid contaminating the pipeline.

[0050] In this embodiment, a first gasket 5 is provided inside the cleaning cover 1; when the cleaning cover 1 is installed on the tee 3, the first gasket 5 is located between the cleaning cover 1 and the tee 3 to play a sealing role.

[0051] In this embodiment, the outer peripheral wall of the cleaning cover 1 is provided with multiple ribs to facilitate the rotation and installation of the cleaning cover 1.

[0052] In this embodiment, when the feed connector 2 is fully installed in the inner cavity 30 of the tee 3, a second gasket 6 is provided between the feed connector 2 and the tee 3 to ensure a sealing effect.

[0053] In this embodiment, the feed connector 2 is installed in the inner cavity 30 of the tee member 3 by a rotating snap fastener;

[0054] The feed connector 2 is provided with a rotating handle 22, which has multiple protruding ridges to facilitate manual selection of the feed connector 2 by the user.

[0055] The rotating handle 22 can be located at the front end of the feed connector 2, and the rear end of the feed connector 2 is provided with a rotating buckle structure that cooperates with the three-way fitting 3.

[0056] In practice, the feed connector 2 can be fixedly connected to the tee 3 through a rotating buckle structure. When the feed connector 2 is fully tightened, its rear end can completely block the connection between the inner cavity 30 and the cleaning port 32. While blocking the connection between the cleaning port 32 and the liquid outlet 31, it can also prevent mosquitoes from entering the cleaning pipeline and avoid contaminating the pipeline.

[0057] In this embodiment, the pipeline quick switching device also includes a flexible connector 4, one end of which is connected to the cleaning cover 1 and the other end is connected to the tee 3.

[0058] The flexible connector 4 may have two collars at both ends, which are respectively fixedly sleeved on the cleaning cover 1 and the tee 3. The two collars can be connected together by a hanging rope, elastic rope, spring, etc.

[0059] In this technology, the cleaning cover 1 is connected to the tee 3 via a flexible connector 4. When the pipeline quick switching device is in the discharge state, although the cleaning cover 1 is not installed on the tee 3, it is still connected to the tee 3, which makes it convenient to use at any time when switching pipelines and is not easy to lose.

[0060] In this embodiment, the flexible connector 4 is a hanging rope, elastic rope, or spring, which is low in cost and easy to obtain materials.

[0061] In this embodiment, the outer peripheral wall of the tee fitting 3 is provided with at least two locking positions 33 for fixing the pipeline quick switching device to the main equipment.

[0062] In practice, the number of locking positions 33 can be two or more, for example, 2 to 4 locking positions 33 symmetrically arranged on the tee member 3.

[0063] In this embodiment, the cleaning port 32 is located at the lowest point of the inner cavity 30 of the tee fitting 3, which facilitates the discharge of residual liquid and helps prevent liquid accumulation in the main equipment pipeline.

[0064] In practice, after cleaning is completed, if there is still liquid inside the pipeline, the liquid can flow through the cleaning port 32 and be discharged from the main equipment through the cleaning pipeline, thereby ensuring that there is no liquid accumulation in the pipeline of the main equipment.

[0065] In another embodiment, the present invention provides a beverage machine that includes a pipeline quick switching device as described in any of the above embodiments, which can conveniently and quickly switch between the dispensing pipeline and the cleaning pipeline, and provides thorough cleaning and convenient maintenance.

[0066] The other components and operation of the pipeline quick switching device and beverage machine according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
