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 have begun to enter thousands of households. Their structure, with a water bucket at the bottom and a kettle at the top, makes them more convenient for consumers to use, resulting in rapid growth in sales.

[0003] Currently, most tea bar machines on the market have cabinets for storing water buckets that can be opened and closed for easy replacement of the buckets and to prevent dust accumulation. To improve the opening and closing experience, a push-to-open mechanism is often installed on the cabinet. Users press the cabinet door to squeeze the button on the push-to-open mechanism, and the button rotates and slides to open or close the cabinet door. However, this structure has the following drawbacks: when the user presses the button through the cabinet door, the button needs to slide and rotate to switch positions. During the rotation of the button, wear and tear is caused on the cabinet door that is in contact with the button. After a long period of wear, the part of the cabinet door that is in contact with the button will be damaged or the paint will peel off, leading to rust on the cabinet door. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tea bar machine to solve the problem of wear and tear on the tea bar machine caused by the pressing and rebound mechanism being pressed by the cabinet body and cabinet door.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A tea bar machine includes a cabinet and a cabinet door installed on the side of the cabinet. A press-and-rebound mechanism is embedded in the cabinet door. The press-and-rebound mechanism includes a button sleeve fixed to the cabinet door, a button slidably connected to the button sleeve, a locking member disposed within the button sleeve, and an elastic member that pushes the locking member towards the button. A positioning protrusion is provided on the inner wall of the button sleeve. When the button is pressed by the cabinet, it pushes the locking member to slide and rotate, so that the locking member switches between a closed position (abutting the positioning protrusion) and an open position (disengaging from the positioning protrusion). When the locking member is in the closed position, the button retracts into the button sleeve; when the locking member is in the open position, the button extends out of the button sleeve under the push of the locking member, thereby pushing the cabinet to open the cabinet door. This technical solution has the following technical effects:

[0006] This invention features a press-and-rebound mechanism on the cabinet door. This mechanism can shorten or extend when pressed, allowing the user to open or close the door by pressing the door itself. By designing the button and button sleeve of the press-and-rebound mechanism as a sliding connection, and incorporating a locking element within the button sleeve that allows for position switching through rotation and sliding, the button, which contacts and abuts against the cabinet, only needs to slide within the button sleeve to switch between popped-out and retracted positions, eliminating the need for button rotation. This prevents wear on the cabinet caused by a rotating button when pressed by the cabinet, thus preventing long-term wear and tear on the button contact area, protecting both the button and the cabinet, enhancing the cabinet's appearance, and extending their lifespan.

[0007] In the aforementioned tea bar machine, multiple positioning protrusions are provided, which are distributed circumferentially along the button sleeve. A guide groove extending axially along the button sleeve is formed between two adjacent positioning protrusions. The locking member includes a base and a limiting protrusion for abutting the positioning protrusions. When the locking member is in the open position, the limiting protrusion is slidably connected in the guide groove. When the limiting protrusion is disengaged from the guide groove, the base rotates under the push of the button, so that the limiting protrusion switches between a position aligned with the guide groove and a position aligned with the positioning protrusion. By setting positioning protrusions distributed circumferentially along the inner wall of the button sleeve, when the button is pressed, the limiting protrusion of the locking member switches from aligning with the positioning protrusion on one side of the guide groove to aligning with the guide groove. When the button is pressed again, the limiting protrusion of the locking member switches from aligning with the guide groove to aligning with the positioning protrusion on the other side of the guide groove. That is, during the pressing of the button, the locking member can always rotate in the same direction to achieve alignment between the limiting protrusion and the guide groove or positioning protrusion, which facilitates the push of the button on the locking member.

[0008] In the aforementioned tea bar machine, an annular stop protrusion is also provided on the inner wall of the button sleeve. The annular stop protrusion is located at the end of the positioning protrusion away from the locking member, so as to form a stop step at the end of the guide groove. The stop step at the end of the guide groove can limit the sliding limit protrusion in the guide groove, so that the limit protrusion stops sliding when it reaches the door opening position, resulting in a good stopping effect.

[0009] In the aforementioned tea bar machine, a sliding protrusion is provided on the outer wall of the button, and the sliding protrusion is slidably connected in a guide groove. This guides the sliding of the button and limits the button's circumferential movement, preventing the button from rotating within the button sleeve and ensuring that the button stably pushes the locking component to slide and rotate.

[0010] In the aforementioned tea bar machine, the end of the button is provided with a pushing protrusion, and the pushing protrusion has a pushing slope. A limiting protrusion has a limiting slope at its end facing the button sleeve. The button pushes the locking component to rotate through the cooperating pushing and limiting slopes. When the end of the pushing slope abuts against the end of the limiting slope, the button pushes the limiting protrusion on the locking component through the pushing protrusion, causing the locking component to slide towards the elastic element. When the limiting protrusion slides out of the guide groove (or disengages from the positioning protrusion), the pushing slope slides along the limiting slope, causing the limiting protrusion to drive the locking component to rotate. The design of the pushing and limiting slopes allows the button to push the locking component not only axially but also circumferentially. The structure is simple, reliable, and easy to manufacture.

[0011] In the aforementioned tea bar machine, the end of the positioning protrusion facing the locking member is provided with a first guide slope and a second guide slope with the same inclination direction. The adjacent ends of the first guide slope and the second guide slope are positioned differently in the axial direction of the button sleeve, so that a groove is formed between them to limit the positioning protrusion. After the positioning protrusion rotates from being opposite to the guide groove to being opposite to the positioning protrusion, it can slide along the first guide slope under the push of the elastic member until it is locked with the groove, preventing the positioning protrusion from freely disengaging from the positioning protrusion and ensuring the locking member is locked in the closed position. When the pushing protrusion pushes the positioning protrusion to rotate and disengage from the groove, the second guide slope can guide the positioning protrusion so that the positioning protrusion can quickly slide into another guide groove.

[0012] In the aforementioned tea bar machine, the cabinet door has a receiving groove with an opening facing the cabinet body. All button sleeves are embedded within this groove. Each button sleeve includes a base housing an elastic element and a sleeve with a positioning protrusion. The end of the sleeve is threadedly connected to the base. This facilitates the installation and removal of the sleeve and base, and also makes the connection between them more stable and reliable.

[0013] The aforementioned tea bar machine also includes an elastic support pad. This elastic support pad comprises an elastic support portion and a fixing portion embedded in the cabinet body or cabinet door. When the cabinet door is closed, the elastic support portion clamps between the cabinet door and the cabinet body, creating a pressing gap between the cabinet door and the cabinet body for the cabinet door to move. The elastic support portion provides a buffer for the cabinet door when the user closes it, preventing the door from directly impacting the cabinet body. It also provides a pressing gap between the cabinet door and the cabinet body for the cabinet door to move, allowing space for the user to press the buttons on the cabinet door by deforming the cabinet body. The structure is simple and easy for the user to operate.

[0014] In the aforementioned tea bar machine, the elastic support part is a corrugated pipe with a support groove, the opening of which is located at the end opposite to the fixed part. Using a corrugated pipe as the elastic support part allows for greater elastic deformation, making it easier for the user to press the cabinet door and improving the user experience. Furthermore, because the elastic support part has a support groove with its opening opposite to the fixed part, when the cabinet door closes onto the cabinet body to compress the elastic support part, a negative pressure can be formed inside the support groove, causing the opening of the support groove to adhere to the cabinet body, resulting in a tighter and more reliable connection between the cabinet body and the cabinet door.

[0015] In the aforementioned tea bar machine, the cabinet door or cabinet body is provided with mounting holes for inserting and fixing parts. The fixing parts have snap-fit ​​protrusions that engage with the cabinet door or cabinet body to prevent the fixing parts from dislodging from the mounting holes. The snap-fit ​​protrusions engaging with the cabinet door enhance the connection strength between the fixing parts and the cabinet door. By abutting against the cabinet door, the snap-fit ​​protrusions prevent the fixing parts from dislodging from the mounting holes, thus preventing the elastic support pad from detaching from the cabinet door when the user opens and closes it, ensuring the elastic support pad works stably on the cabinet door.

[0036] This utility model discloses a tea bar machine, including a cabinet and a cabinet door installed on the side of the cabinet. A press-and-rebound mechanism is embedded in the cabinet door. The press-and-rebound mechanism includes a button sleeve fixed to the cabinet door, a button slidably connected to the button sleeve, a locking member disposed within the button sleeve, and an elastic member that pushes the locking member towards the button. A positioning protrusion is provided on the inner wall of the button sleeve. When the button is pressed by the cabinet, it pushes the locking member to slide and rotate, causing the locking member to switch between a closed position (abutting the positioning protrusion) and an open position (disengaging from the positioning protrusion). When the locking member is in the closed position, the button retracts into the button sleeve; when the locking member is in the open position, the button extends out of the button sleeve under the push of the locking member, thus pushing the cabinet to open the cabinet door. This utility model, by providing a press-and-rebound mechanism on the cabinet door, which can shorten or extend when pressed, allows the user to press the mechanism by pressing the cabinet door, thereby opening or closing the cabinet door. By designing the button and button sleeve of the press-and-rebound mechanism into a sliding connection structure, and incorporating a locking element within the button sleeve that allows for position switching through rotation and sliding, the button, which contacts and abuts against the cabinet, only needs to slide within the button sleeve to switch and lock between the pop-out and retracted positions. This eliminates the need for the button to rotate, preventing wear on the cabinet caused by a rotating button when pressed by the cabinet. Consequently, it prevents long-term wear and tear on the cabinet's contact points, thus protecting both the button and the cabinet, enhancing the cabinet's aesthetics, and extending the lifespan of both.

[0042] Example 1:

[0043] A tea bar machine, such as Figures 1 to 9As shown, the system includes a cabinet body 100 and a cabinet door 200. The cabinet door 200 is installed on the side of the cabinet body 100 for opening and closing the cavity in the cabinet body 100 that houses the water bucket 110. The cabinet door 200 has a receiving groove 210 with an opening facing the cabinet body 100. A press-and-rebound mechanism is embedded in the receiving groove 210. The press-and-rebound mechanism includes a button sleeve 300, a button 400, a locking element 500, and an elastic element 600. The button sleeve 300 is fixed in the receiving groove 210 on the cabinet door 200. The button 400 is slidably connected to the button sleeve 300 and can only slide along the axial direction of the button sleeve 300. The locking element 500 and the elastic element 600 are located inside the button sleeve 300. The elastic element 600 abuts against the locking element 500 and the button sleeve 300 respectively, pushing the locking element 500 towards the button 400. A positioning protrusion 321 is provided on the inner side wall of the button sleeve 300. The locking member 500 can slide and rotate inside the button sleeve 300. The locking member 500 has a closed position and an open position. When the user presses the cabinet door 200, the button 400 is pressed by the cabinet body 100 and pushes the locking member 500 to slide and rotate, so that the locking member 500 switches between the closed position and the open position.

[0044] When cabinet door 200 is closed, button 400 retracts into button sleeve 300, such as Figure 7 As shown, when the locking member 500 is in the closed position, it abuts against the positioning protrusion 321 under the push of the elastic member 600. The button sleeve 300 locks the locking member 500 through the positioning protrusion 321. The elastic member 600 is compressed under the pressure of the locking member 500 and the button sleeve 300. At this time, if the user presses the cabinet door 200, the cabinet body 100 presses the part of the button 400 outside the button sleeve 300 towards the cabinet door 200. The button 400 slides towards the button sleeve 300 to press the locking member 500 towards the elastic member 600 until the button 400 is completely retracted into the button sleeve 300, thus locking the door. The locking member 500, which cooperates with the button 400, is released from the closed position. The locking member 500 slides and rotates under the push of the button 400 to disengage from the positioning protrusion 321. The locking member 500 is no longer opposite the positioning protrusion 321 in the axial direction of the button sleeve 300. When the user releases the cabinet door 200, the elastic member 600, which is in a compressed state, pushes the locking member 500 towards the button 400. The locking member 500, which is no longer blocked by the positioning protrusion 321, drives the button 400 to pop out of the button sleeve 300 under the push of the elastic member 600, so that the button 400 pushes the cabinet body 100 to open the cabinet door 200.

[0045] When cabinet door 200 is in the open position, button 400 extends from button sleeve 300, such as Figure 6As shown, when the locking member 500 is in the open position, if the user closes the cabinet door 200, the cabinet body 100 pushes the button 400 towards the cabinet door 200. The button 400 slides towards the button sleeve 300 and presses the locking member 500 towards the elastic member 600 until the button 400 is fully retracted into the button sleeve 300, so as to disengage the locking member 500 from the open position. The locking member 500 slides and rotates under the push of the button 400, so as to rotate to a position opposite to the positioning protrusion 321 on the axial direction of the button sleeve 300. When the user releases the cabinet door 200, the locking member 500 abuts against the positioning protrusion 321 under the push of the elastic member 600, so as to lock the locking member 500 in the closed position.

[0046] This utility model provides a press-and-rebound mechanism on the cabinet door 200. The press-and-rebound mechanism can shorten or extend when pressed, allowing the user to press the cabinet door 200 to open or close the cabinet door 200 by pressing the press-and-rebound mechanism. By configuring the button 400 and button sleeve 300 of the press-and-rebound mechanism into a sliding connection structure, and by setting a locking element 500 inside the button sleeve 300 that can switch positions by rotation and sliding, the button 400, which is used to contact and abut against the cabinet 100, only needs to slide within the button sleeve 300 to switch and lock between the pop-out and retracted positions of the button 400. This eliminates the need for the button 400 to rotate, thus preventing wear on the cabinet 100 caused by the rotating button 400 when the cabinet 100 presses against it. This also prevents long-term wear and tear on the position of the cabinet 100 that abuts the button 400, leading to damage, paint peeling, or corrosion. This protects both the button 400 and the cabinet 100, making the cabinet 100 more aesthetically pleasing and extending the service life of both.

[0047] In this embodiment, multiple positioning protrusions 321 are provided, and the multiple positioning protrusions 321 are evenly distributed along the circumference of the key sleeve 300. A guide groove 322 is formed between two adjacent positioning protrusions 321, and the guide groove 322 extends along the axial direction of the key sleeve 300. The locking member 500 includes a base 510 and multiple limiting protrusions 520 provided on the base 510. The multiple limiting protrusions 520 protrude from the outer surface of the base 510 and are evenly distributed along the circumference of the key sleeve 300. The end of the limiting protrusion 520 facing the key 400 is used to abut against the positioning protrusion 321.

[0048] When the locking member 500 is in the closed position, the limiting protrusion 520 of the locking member 500 abuts against the positioning protrusion 321. At this time, if the button 400 is pressed, the button 400 pushes the limiting protrusion 520, causing the locking member 500 to slide and rotate towards the elastic member 600, so that the limiting protrusion 520 disengages from the positioning protrusion 321. When the button 400 is fully retracted into the button sleeve 300, the limiting protrusion 520 and the guide groove 322 are aligned axially. When the button 400 is released, the locking member 500, under the push of the elastic member 600, causes the limiting protrusion 520 to slide towards the guide groove 322. While the limiting protrusion 520 slides in the guide groove 322, it pushes the button 400 out of the button sleeve 300, causing the button 400 to pop out of the button sleeve 300 until the locking member 500 slides to the open position. At this time, if button 400 is pressed again, button 400 pushes the limiting protrusion 520, causing the locking member 500 to slide towards the elastic member 600, so that the limiting protrusion 520 disengages from the guide groove 322. When button 400 is fully retracted into button sleeve 300, the limiting protrusion 520 drives the base 510 to rotate under the push of button 400, so that the limiting protrusion 520 and the positioning protrusion 321 on the other side of guide groove 322 are aligned axially. When button 400 is released, the locking member 500 drives the limiting protrusion 520 to abut against the positioning protrusion 321 on the other side of guide groove 322 under the push of elastic member 600. By providing positioning protrusions 321 distributed circumferentially along the inner wall of the button sleeve 300, when the button 400 is pressed, the limiting protrusion 520 of the locking member 500 switches from being aligned with the positioning protrusion 321 on one side of the guide groove 322 to being aligned with the guide groove 322. When the button 400 is pressed again, the limiting protrusion 520 of the locking member 500 switches from being aligned with the guide groove 322 to being aligned with the positioning protrusion 321 on the other side of the guide groove 322. That is, during the pressing of the button 400, the locking member 500 can achieve the alignment of the limiting protrusion 520 with the guide groove 322 or the positioning protrusion 321 by rotating only in the same direction, which facilitates the pushing of the button 400 on the locking member 500.

[0049] Preferably, an annular stop protrusion 323 is also provided on the inner wall of the button sleeve 300. The annular stop protrusion 323 is located at the end of the positioning protrusion 321 away from the locking member 500, so as to form a stop step 3231 at the end of the guide groove 322. The stop step 3231 at the end of the guide groove 322 can limit the sliding limit protrusion 520 in the guide groove 322, so that the limit protrusion 520 stops sliding when it reaches the door opening position, and the stopping effect is good.

[0050] In this embodiment, multiple sliding protrusions 410 are provided on the outer wall of the button 400. Each sliding protrusion 410 corresponds to a guide groove 322. The sliding protrusions 410 are slidably connected within the guide grooves 322 to guide the sliding of the button 400 and limit its circumferential movement, preventing rotation within the button sleeve 300 and ensuring stable pushing of the locking member 500 to slide and rotate. Because the sliding protrusions 410 directly engage with the guide grooves 322, the guide grooves 322 can guide and limit not only the limiting protrusions 520 but also the button 400, simplifying the internal structure of the button sleeve 300 and reducing manufacturing difficulty. The sliding protrusions 410 can also abut against the stop step 3231 to prevent the button 400 from disengaging from the button sleeve 300 under the push of the locking member 500, providing a good limiting effect.

[0051] In this embodiment, as Figure 4 As shown, the end of the button 400 is provided with multiple pushing protrusions 420. The multiple pushing protrusions 420 are arranged on the end of the button 400 facing the locking member 500 so that the end of the button 400 is serrated. Each pushing protrusion 420 is provided with a pushing inclined surface 421 with the same slope. At the end of the limiting protrusion 520 facing the button sleeve 300, there is a limiting inclined surface 521 with the same tilt direction as the pushing inclined surface 421. The button 400 pushes the locking member 500 to rotate through the cooperating pushing inclined surface 421 and limiting inclined surface 521. When the end of the pushing inclined surface 421 abuts against the end of the limiting inclined surface 521, the button 400 pushes the limiting protrusion 520 on the locking member 500 through the pushing protrusion 420, causing the locking member 500 to slide towards the elastic member 600. When the limiting protrusion 520 slides out of the guide groove 322 (or disengages from the positioning protrusion 321), the pushing inclined surface 421 slides along the limiting inclined surface 521, causing the limiting protrusion 520 to drive the locking member 500 to rotate. The arrangement of the pushing inclined surface 421 and the limiting inclined surface 521 allows the button 400 to push the locking member 500 not only axially but also circumferentially. The structure is simple, reliable, and easy to manufacture.

[0052] like Figure 5As shown, the end of the positioning protrusion 321 facing the locking member 500 is provided with a first guide slope 3211 and a second guide slope 3212. The first guide slope 3211 and the second guide slope 3212 have the same inclination direction, but the adjacent ends of the first guide slope 3211 and the second guide slope 3212 are positioned differently in the axial direction of the key sleeve 300, so as to form a groove 3213 between them, so that the limiting protrusion 520 rotates from being opposite to the guide groove 322 to being opposite to the positioning protrusion 3211. After being aligned, the locking member 500 can slide along the first guide slope 3211 under the push of the elastic member 600 until it is locked with the slot 3213, preventing the limiting protrusion 520 from freely disengaging from the positioning protrusion 321, and ensuring that the locking member 500 is locked in the closed position. When the pushing protrusion 420 pushes the limiting protrusion 520 to rotate and disengage from the slot 3213, the second guide slope 3212 can guide the limiting protrusion 520 so that the limiting protrusion 520 can quickly slide into another guide groove 322.

[0053] The button sleeve 300 in this embodiment includes a base 310 and a sleeve 320. An elastic element 600 is accommodated in the base 310, and a positioning protrusion 321 is provided in the sleeve 320. The end of the sleeve 320 is threadedly connected to the base 310, which facilitates the installation and disassembly of the sleeve 320 and the base 310, and at the same time makes the connection between the two more stable and reliable.

[0054] like Figure 2 As shown, in this embodiment, an elastic support pad 700 is provided on the cabinet door 200. The elastic support pad 700 is arranged adjacent to the pressing and rebounding mechanism. The elastic support pad 700 includes an elastic support part 720 and a fixing part 710 embedded in the cabinet door 200. When the cabinet door 200 is closed, the elastic support part 720 is clamped between the cabinet door 200 and the cabinet body 100 to form a pressing gap between the cabinet door 200 and the cabinet body 100. When the user presses the cabinet door 200, the elastic support part 720 can be deformed by force to create a reserved space for the cabinet door 200 to move. The gap between the cabinet body 100 and the cabinet door 200 is reduced to compress the button 400, thus enabling the button 400 to be pressed. In other words, the elastic support part 720 provides a buffer for the cabinet door 200 when the user closes it, preventing the door from directly impacting the cabinet body 100. It also provides a pressing gap between the door 200 and the cabinet body 100, allowing the door to move and providing space for the user to press the button 400 on the cabinet door 200 by deforming the cabinet body 100. This design is simple and easy for the user to operate. Of course, in another embodiment, the elastic support pad can also be installed on the cabinet body.

[0055] The cabinet door 200 is provided with a mounting hole 220, and the fixing part 710 is inserted into the mounting hole 220. The fixing part 710 is provided with a snap-fit ​​protrusion 711, which snaps into the cabinet door 200, thereby enhancing the connection strength between the fixing part 710 and the cabinet door 200. The snap-fit ​​protrusion 711 can abut against the cabinet door 200 to prevent the fixing part 710 from coming out of the mounting hole 220, thus preventing the elastic support pad 700 from coming off the cabinet door 200 when the user opens and closes the cabinet door 200, and ensuring that the elastic support pad 700 works stably on the cabinet door 200.

[0056] In this embodiment, it is preferred that, as Figure 9 As shown, the elastic support 720 is a corrugated tube, one end of which is closed by the fixing part 710 to form a support groove 721 on the elastic support 720 with an opening facing away from the fixing part 710. Using a corrugated tube as the elastic support 720 gives it a large elastic deformation, making it easier for the user to press the cabinet door 200 and improving the user's operating experience. Also, because the elastic support 720 has a support groove 721 with an opening facing away from the fixing part 710, when the cabinet door 200 closes onto the cabinet body 100 to squeeze the elastic support 720, a negative pressure can be formed inside the support groove 721, causing the opening of the support groove 721 to be sucked onto the cabinet body 100, making the connection between the cabinet body 100 and the cabinet door 200 tighter and more reliable.

[0057] like Figure 2 As shown, in this embodiment, a magnetic component 800 is also provided inside the cabinet door 200. The magnetic component 800 achieves the closure of the cabinet door 200 on the cabinet body 100 by magnetically engaging with the cabinet body 100. The magnetic component 800 is located on the side of the elastic support pad 700 away from the press-and-rebound mechanism. While enhancing the closing effect between the cabinet body 100 and the cabinet door 200, it also allows the press-and-rebound mechanism to overcome the magnetic force between the magnetic component 800 and the cabinet body 100 with a small amount of elastic force, so as to open the cabinet door 200 and improve the user experience.

[0058] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. 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.
