Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment, specifically relating to a tea bar machine. Background Technology

[0002] In recent years, with the improvement of living standards, tea bar machines, with bottled water underneath and an electric kettle on top, have become increasingly convenient for consumers and are gradually replacing traditional water dispensers. Most existing tea bar machines use bottled water, but the quality of bottled water varies, sometimes resulting in poor taste. Furthermore, bottled water cannot be completely isolated from air, and if left in the tea bar machine for too long, bacteria can easily grow, posing a safety hazard. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tea bar machine to solve at least one of the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A tea bar machine includes a cabinet, inside which is a water tank and a water circuit assembly for drawing water from the water tank. A pre-filter is connected between the water tank and the water circuit assembly. The pre-filter has a switching channel, a water passage chamber, and a purified water chamber with a filter element. The water passage chamber is connected to the outlets of the water circuit assembly and the purified water chamber. The switching channel has an inlet connected to the water tank, a first outlet connected to the water passage chamber, and a second outlet connected to the inlet of the purified water chamber. The pre-filter also has a water circuit switching component movably connected within the switching channel. The water circuit switching component moves within the switching channel to connect the inlet with either the first or second outlet. This technical solution has the following technical effects:

[0005] This invention involves installing a pre-filter between the water tank and the water circuit assembly. The drinking water in the tank first passes through the pre-filter before flowing to the water circuit assembly. Because the pre-filter contains a switching channel and a water circuit switching component, users can move the water circuit switching component to change its position within the switching channel if the bottled water quality, taste, or cleanliness is poor. This connects the inlet to the second outlet, allowing the drinking water entering the switching channel through the inlet to enter the purification chamber through the second outlet. After being filtered by the filter element... Water flows from the outlet of the purification chamber into the water passage chamber, and finally into the water circuit assembly. This improves taste and cleanliness, eliminates drinking water safety hazards, and enhances the user's drinking experience. When the bottled water quality, taste, or cleanliness is good, the user can move the water circuit switching component to change its position within the switching channel, connecting the inlet to the first outlet. This allows drinking water entering the switching channel through the inlet to directly enter the water passage chamber through the first outlet and ultimately flow into the water circuit assembly. In other words, the pre-filter has two water paths: one filters the flowing water, and the other allows direct flow. Users can move the water circuit switching component to choose whether to filter the water passing through the pre-filter, improving the user experience and making the tea bar machine compatible with various bottled waters. The mechanical structure of the water circuit switching component ensures stable and reliable switching, guaranteeing stable operation of the pre-filter and extending its lifespan.

[0006] In the aforementioned tea bar machine, the water inlet is located between the first and second water outlets. The water path switching component includes a push rod with a water-sealing part. The push rod has a first position and a second position. When the push rod is in the first position, the water-sealing part is positioned between the water inlet and the second water outlet, allowing the water inlet to communicate with the first water outlet. When the push rod is in the second position, the water-sealing part is positioned between the water inlet and the first water outlet, allowing the water inlet to communicate with the second water outlet. Water entering the switching channel through the water inlet flows out through the second water outlet. The cooperation between the push rod and the switching channel simplifies the structure of the water path switching component, making operation simple and improving the user experience.

[0007] In the aforementioned tea bar machine, the water-sealing part consists of a sealing rib surrounding the push rod. The sealing rib has a sealing groove, and a first sealing ring is installed within the sealing groove, abutting against the inner wall of the switching channel. The first sealing ring enhances the seal between the water-sealing part and the interior of the switching channel, preventing water flow. The sealing groove limits the movement of the first sealing ring, allowing it to move with the sealing rib within the switching channel. This prevents friction between the first sealing ring and the inner wall of the switching channel from causing the first sealing ring to detach from the sealing rib, thus ensuring the seal between the water-sealing part and the switching channel.

[0008] In the aforementioned tea bar machine, the pre-filter includes a main body with a switching channel. The main body is equipped with a push-type elastic self-locking mechanism connected to a push rod. When the push-type elastic self-locking mechanism is pressed, it drives the push rod to switch between a first position and a second position.

[0009] In the aforementioned tea bar machine, two sealing gaskets are provided on the inner wall of the switching channel opening, and a second sealing ring is clamped between the two sealing gaskets, abutting against the outer periphery of the push rod. The second sealing ring abuts against the outer periphery of the push rod to seal the opening of the switching channel and the push rod, preventing water leakage from the switching channel and improving the sealing performance of the switching channel.

[0010] In the aforementioned tea bar machine, the press-type elastic self-locking mechanism includes a button embedded in the main body, a push rod mounted on a push rod, a sleeve sleeved outside the push rod, a pressure rod slidably connected inside the sleeve, and an elastic element for pushing the push rod towards the button. The sleeve is fixed to the main body, one end of the pressure rod is connected to the button, and the other end cooperates with the push rod to drive the push rod to move. The press-type elastic self-locking mechanism allows the user to switch the position of the push rod with a single press of the button, making operation simple and convenient.

[0011] In the aforementioned tea bar machine, a positioning protrusion is provided on the inner wall of the sleeve, a first ratchet is provided at the end of the push rod, and a second ratchet is provided at the end of the pressure rod for pushing the first ratchet. When the push rod is in the first position, the first ratchet abuts against the positioning protrusion; when the push rod is in the second position, the first ratchet disengages from the positioning protrusion. When the button is pressed, the button drives the pressure rod to move towards the elastic element. The pressure rod pushes the first ratchet through the second ratchet, thereby driving the push rod to squeeze the elastic element. During the user's pressing process, the first ratchet slides in the slide groove until it disengages from the slide groove. Under the push of the second ratchet, the first ratchet rotates until it aligns with the positioning protrusion on one side of the slide groove. When the user stops pressing the button, the push rod, under the push of the elastic element, drives the push rod to abut against the positioning protrusion, so that the push rod remains in the first position. When the user presses the button again, the pressure rod, through the engagement of the second and first ratchet teeth, drives the push rod to rotate. This, in turn, rotates the first ratchet tooth until it aligns with the groove on the other side adjacent to the positioning protrusion. After the user releases the button, the push rod, pushed by the elastic element, causes the first ratchet tooth of the push rod to slide into the groove, disengaging from the positioning protrusion and moving the push rod to the second position. By providing positioning protrusions distributed circumferentially on the inner wall of the sleeve, the first ratchet tooth can always rotate in the same direction when switching between the groove and the positioning protrusion, facilitating the push rod's movement.

[0012] In the aforementioned tea bar machine, an elastic element is sleeved on the end of the push rod furthest from the button. One end of the elastic element abuts against the water-sealing part, and the other end abuts against the inner wall of the switching channel. By sleeved on the push rod, the push rod can radially limit the elastic element, ensuring that the elastic element always abuts against the water-sealing part, guaranteeing stable pushing of the push rod by the elastic element, and thus ensuring stable switching of the push rod position.

[0013] In the aforementioned tea bar machine, the cabinet is equipped with a middle plate, which divides the cabinet into an upper cavity containing the water circuit assembly and a lower cavity for accommodating the water bucket. A pre-filter is installed at the bottom of the middle plate, and its outlet connector passes through the middle plate and connects to the water circuit assembly. Because the lower cavity is used for loading and unloading water buckets, it is typically an open and spacious area, offering the advantage of easy opening and closing. The pre-filter, installed at the bottom of the middle plate, utilizes the space between the middle plate and the water bucket, facilitating connection to the bucket and allowing the user to easily reach into the lower cavity to operate the water circuit switching assembly, thus enhancing the user experience.

[0014] In the aforementioned tea bar machine, the pre-filter includes a main body, a lower housing, and a top cover. The lower housing is threadedly connected to the lower part of the main body to form a water purification chamber for accommodating the filter element. The top cover is fitted onto the top of the main body to form a water passage chamber, and the water outlet is located on the top cover. By designing the pre-filter into a three-section structure, it facilitates filter element replacement and user disassembly and cleaning of the pre-filter, ensuring its cleanliness and improving the user experience.

[0015] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0032] This utility model proposes a tea bar machine, including a cabinet, a water tank inside the cabinet, and a water circuit assembly for drawing water from the water tank. A pre-filter is connected between the water tank and the water circuit assembly. The pre-filter has a switching channel, a water passage chamber, and a purified water chamber with a filter element. The water passage chamber is connected to the outlets of the water circuit assembly and the purified water chamber. The switching channel has an inlet connected to the water tank, a first outlet connected to the water passage chamber, and a second outlet connected to the inlet of the purified water chamber. The pre-filter also has a water circuit switching assembly movably connected within the switching channel. The water circuit switching assembly moves within the switching channel to connect the inlet with either the first or second outlet. This invention involves installing a pre-filter between the water tank and the water circuit assembly. The drinking water in the tank first passes through the pre-filter before flowing to the water circuit assembly. Because the pre-filter contains a switching channel and a water circuit switching component, users can move the water circuit switching component to change its position within the switching channel if the bottled water quality, taste, or cleanliness is poor. This connects the inlet to the second outlet, allowing the drinking water entering the switching channel through the inlet to enter the purification chamber through the second outlet. After being filtered by the filter element... Water flows from the outlet of the purification chamber into the water passage chamber, and finally into the water circuit assembly. This improves taste and cleanliness, eliminates drinking water safety hazards, and enhances the user's drinking experience. When the bottled water quality, taste, or cleanliness is good, the user can move the water circuit switching component to change its position within the switching channel, connecting the inlet to the first outlet. This allows drinking water entering the switching channel through the inlet to directly enter the water passage chamber through the first outlet and ultimately flow into the water circuit assembly. In other words, the pre-filter has two water paths: one filters the flowing water, and the other allows direct flow. Users can move the water circuit switching component to choose whether to filter the water passing through the pre-filter, improving the user experience and making the tea bar machine compatible with various bottled waters. The mechanical structure of the water circuit switching component ensures stable and reliable switching, guaranteeing stable operation of the pre-filter and extending its lifespan.

[0038] Example 1:

[0039] A tea bar machine, such as Figures 1 to 8As shown, the system includes a cabinet 100, which houses a water tank and a water circuit assembly. The water circuit assembly draws water from the water tank into a kettle placed on top of the cabinet 100. A pre-filter 200 is connected between the water tank and the water circuit assembly. The pre-filter 200 has a switching channel 330, a water passage chamber 310, and a purified water chamber 410. The purified water chamber 410 contains a filter element 411 for filtering the water flowing through it. The switching channel 330 is located between the water passage chamber 310 and the purified water chamber 410, and includes an inlet 331, a first outlet 332, and a second outlet. The inlet 331 is connected to the water tank via a pipe, the first outlet 332 is connected to the water passage chamber 310, the water passage chamber 310 is connected to the water circuit assembly, the second outlet 333 is connected to the water inlet of the water purification chamber 410, and the water outlet of the water purification chamber 410 is connected to the water passage chamber 310 via a water passage hole 336. The pre-filter water purifier 200 also has a water circuit switching assembly 600, which is movably connected in the switching channel 330. The water circuit switching assembly 600 moves within the switching channel 330 to connect the inlet 331 to either the first outlet 332 or the second outlet 333.

[0040] This invention features a pre-filter 200 installed between the water tank and the water circuit assembly. The drinking water in the tank first passes through the pre-filter 200 before flowing to the water circuit assembly. Because the pre-filter 200 contains a switching channel 330 and a water circuit switching component 600, users can move the water circuit switching component 600 to change its position within the switching channel 330 if the bottled water quality, taste, or cleanliness is poor. This connects the inlet 331 to the second outlet 333, allowing the drinking water entering the switching channel 330 through the inlet 331 to enter the purification chamber 410 through the second outlet 333, and then pass through the filter element 411. After filtration, the water flows out through the outlet of the purified water chamber 410 into the water passage chamber 310, and finally flows into the water circuit assembly from the water passage chamber 310 to improve the taste and cleanliness, eliminate drinking water safety hazards, and make the user's drinking experience better. When the bottled water quality, taste or cleanliness is good, the user can move the water circuit switching component 600 to change its position in the switching channel 330, so that the inlet 331 is connected to the first outlet 332, so that the drinking water entering the switching channel 330 through the inlet 331 directly enters the water passage chamber 310 through the first outlet 332, and finally flows into the water circuit assembly from the water passage chamber 310. That is, the pre-filter 200 has two water channels. One water channel can filter the flowing water, and the other water channel allows the water to flow directly. Users can move the water channel switching component 600 to select whether to filter the water flowing through the pre-filter 200, which improves the user experience and makes the tea bar machine suitable for various bottled water. The mechanical structure of the water channel switching component 600 makes the water channel switching more stable and reliable, ensuring the stable operation of the pre-filter 200 and extending the service life of the pre-filter 200.

[0041] In this embodiment, as Figure 4As shown, the first outlet 332 and the second outlet 333 are distributed along the axial direction of the switching water path. The inlet 331 is located between the first outlet 332 and the second outlet 333. The water path switching assembly 600 includes a push rod 610 passing through the switching channel 330. The push rod 610 is provided with a water-sealing part 611, which can cut off the water flow by abutting against the inner wall of the switching channel 330. The push rod 610 has a first position and a second position. When the push rod 610 is in the first position, the water-sealing part 611 is located between the inlet 331 and the second outlet 333 to separate the inlet 331 and the second outlet 333, so that the inlet 331 and the first outlet 332 are connected through the switching channel 330, and the water flowing into the switching channel 330 through the inlet 331 will flow out through the first outlet 332. When the push rod 610 is in the second position, the water-sealing part 611 is located between the inlet 331 and the second outlet 333 to separate the inlet 331 and the second outlet 333, so that the inlet 331 and the first outlet 332 are connected through the switching channel 330, and the water flowing into the switching channel 330 through the inlet 331 will flow out through the first outlet 332. When the push rod 610 is in the second position, the water-sealing part 611 is located between the inlet 331 and the second outlet 333. 611 is located between the inlet 331 and the first outlet 332 to separate the inlet 331 and the first outlet 332, allowing the inlet 331 and the second outlet 333 to be connected through the switching channel 330. Water flowing into the switching channel 330 through the inlet 331 will flow out through the second outlet 333. The cooperation between the push rod 610 and the switching channel 330 simplifies the structure of the water circuit switching component 600, making it easier for users to operate and improving the user experience. Preferably, as... Figure 8 As shown, in this embodiment, the water-sealing part 611 is a sealing rib 6111 surrounding the push rod 610. An annular sealing groove 6112 is provided on the outer periphery of the sealing rib 6111. A first sealing ring 6113 is installed in the sealing groove 6112. The first sealing ring 6113 protrudes from the sealing groove 6112 to abut against the inner wall of the switching channel 330. The setting of the first sealing ring 6113 can enhance the sealing between the water-sealing part 611 and the interior of the switching channel 330, preventing water from flowing through. The setting of the sealing groove 6112 can limit the first sealing ring 6113, so that the first sealing ring 6113 can move with the sealing rib 6111 in the switching channel 330, preventing the friction between the first sealing ring 6113 and the inner wall of the switching channel 330 from causing the first sealing ring 6113 to detach from the sealing rib 6111, thereby ensuring the sealing between the water-sealing part 611 and the switching channel 330.

[0042] Two sealing gaskets 334 are fixed on the inner wall of the opening of the switching channel 330. A second sealing ring 335 is clamped between the two sealing gaskets 334. The second sealing ring 335 abuts against the outer periphery of the part of the push rod 610 that extends into the switching channel 330, so as to seal the opening of the switching channel 330 and the push rod 610, prevent water leakage from the switching channel 330, and improve the sealing performance of the switching channel 330.

[0043] like Figure 1As shown, in this embodiment, a middle plate 110 is provided inside the cabinet 100. The middle plate 110 divides the cabinet 100 into an upper cavity 120 and a lower cavity 130. The upper cavity 120 is located above the middle plate 110 to accommodate the circuit board and water circuit components. The lower cavity 130 is located below the middle plate 110 to accommodate the water tank. The pre-filter 200 is installed at the bottom of the middle plate 110 for easy installation and removal. The top of the pre-filter 200 is provided with a water outlet connector 510, which passes through the middle plate 110 and connects to the water circuit components. Because the lower cavity 130 is used to access the water tank, it is usually an open space and relatively spacious, with the advantage of easy opening and closing. The pre-filter 200 installed at the bottom of the middle plate 110 utilizes the space between the middle plate 110 and the water tank, facilitating its connection to the water tank and allowing the user to easily reach into the lower cavity 130 to operate the water circuit switching component 600, thus improving the user's operating experience.

[0044] Preferably, the pre-filter 200 includes a main body 300, a lower housing 400, and a top cover 500. The lower housing 400 is threaded to the lower part of the main body 300 to form a water purification chamber 410. The filter element 411 is disposed in the water purification chamber 410. The top cover 500 covers the top of the main body 300 to form a water passage chamber 310. The water outlet connector 510 is disposed on the top cover 500. By setting the pre-filter 200 into a three-section structure, it is convenient to replace the filter element 411, and it is also convenient for users to disassemble and clean the pre-filter 200, ensuring the cleanliness of the pre-filter 200 and improving the user experience.

[0045] In this embodiment, the water path switching assembly 600 further includes a press-type elastic self-locking mechanism 620. The pre-filter 200 includes a main body 300, and a switching channel 330 is disposed on the main body 300. The press-type elastic self-locking mechanism 620 is installed on the main body 300 and connected to the push rod 610. When the press-type elastic self-locking mechanism 620 is pressed, it will drive the push rod 610 to switch between a first position and a second position. That is, if the push rod 610 moves from the first position to the second position when pressed for the first time, then when pressed again, the push rod 610 will move from the second position to the first position. This process is repeated to achieve the switching of the position of the push rod 610. The press-type elastic self-locking mechanism 620 can not only realize the switching of the push rod 610 between the first position and the second position, but also lock and position the push rod 610 in the first position and the second position. When the user does not press it, the push rod 610 is held in the first position or the second position, which is convenient for the user to press and operate, and is more stable and reliable.

[0046] In this embodiment, the press-type elastic self-locking mechanism 620 includes a button 621, a push rod 622, a sleeve 623, a pressure rod 624, and an elastic element 625. The sleeve 623 is threaded onto the main body 300 to press the sealing gasket 334 and the second sealing ring 335 onto the main body 300, preventing the sealing gasket 334 and the second sealing ring 335 from moving axially along the switching channel 330. The push rod 622 is sleeved on one end of the push rod 610 that extends out of the switching channel 330, and the push rod 622 faces one side of the switching channel 330. The push rod 624 is slidably connected to the push rod 610 and abuts against the push rod 610. The sleeve 623 is sleeved on the outside of the push rod 622. The pressure rod 624 is slidably connected to the sleeve 623 and sleeved on the push rod 610. The button 621 is embedded in the body 300 and slidably connected to the body 300. One end of the pressure rod 624 extending out of the sleeve 623 is connected to the button 621. The other end of the pressure rod 624 located in the sleeve 623 cooperates with the push rod 622. The elastic element 625 abuts against the end of the push rod 610 away from the button 621 to push the push rod 610 toward the button 621.

[0047] Multiple circumferentially spaced positioning protrusions 6231 are provided on the inner wall of the sleeve 623. A groove 6232 is formed between two adjacent positioning protrusions 6231. The groove 6232 extends axially along the sleeve 623. The end of the push rod 622 is provided with a first ratchet 6221, and the end of the pressure rod 624 is provided with a second ratchet 6241. A slider 6242 is provided on the outer wall of the pressure rod 624. The pressure rod cooperates with the groove 6232 through the slider 6242 to realize the sliding connection between the pressure rod 624 and the sleeve 623. When the button 621 is pressed, the button 621 drives the pressure rod 624 to move towards the elastic element 625. When the user presses the button 621, the pressure rod 624 pushes the first ratchet 6221 through the second ratchet 6241, which in turn drives the push rod 610 to squeeze the elastic element 625. During the user's press, the first ratchet 6221 slides in the slide groove 6232 until the first ratchet 6221 disengages from the slide groove 6232. At this time, the first ratchet 6221 rotates under the push of the second ratchet 6241 until it aligns with the positioning protrusion 6231 on one side of the slide groove 6232. When the user stops pressing the button 621, the push rod 610 drives the top rod 622 to abut against the positioning protrusion 6231 under the push of the elastic element 625, so that the push rod 610 is maintained in the first position. When the user presses button 621 again, the pressure rod 624, through the engagement of the second ratchet 6241 and the first ratchet 6221, drives the push rod 622 to rotate. This, in turn, rotates the first ratchet 6221 until it aligns with the groove 6232 on the other side adjacent to the positioning protrusion 6231. After the user releases button 621, the push rod 610, pushed by the elastic element 625, causes the first ratchet 6221 of the push rod 622 to slide into the groove 6232, disengaging from the positioning protrusion 6231, thus moving the push rod 610 to the second position. By providing positioning protrusions 6231 distributed circumferentially along the inner wall of the sleeve 623, the first ratchet 6221 can always rotate in the same direction when switching between the groove 6232 and the positioning protrusion 6231, facilitating the push rod 622 by the pressure rod 624.

[0048] Preferably, the elastic element 625 is sleeved on the end of the push rod 610 away from the button 621. One end of the elastic element 625 abuts against the side of the water-sealing part 611, and the other end abuts against the inner wall of the switching channel 330. By sleeved on the push rod 610, the push rod 610 can radially limit the elastic element 625, ensuring that the elastic element 625 always abuts against the water-sealing part 611, ensuring stable pushing of the push rod 610 by the elastic element 625, and thus ensuring stable switching of the push rod 610 position.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
