Description

Technical Field

[0001] This utility model relates to the field of iron technology, and in particular to an automatic water tank ejection mechanism. Background Technology

[0002] An electric iron is a cleaning appliance that uses electric heat to iron clothes. It is one of the essential appliances in modern households and a tool for smoothing clothes and fabrics. Most electric irons consist of an iron body and a water tank. In most cases, the water tank is molded as one piece with the iron body, making it difficult to separate the water tank from the iron body, which makes adding water inconvenient. In addition, a small number of irons on the market have a separate water tank and iron body, meaning that the water tank can be detached and installed on the iron body. It can be removed when water needs to be added. Generally, the detachable connection is achieved by a screw-on structure. However, when adding water or cleaning, it is found that the connection is too tight, making it inconvenient to disassemble. Moreover, water in the tank is prone to spilling out during disassembly. Utility Model Content

[0003] The purpose of this utility model is to design an automatic water tank ejection mechanism to overcome the shortcomings of the above-mentioned technology.

[0004] This utility model designs an automatic water tank ejection mechanism, including an iron body with an installation cavity. A removable water tank is embedded in the installation cavity. An ejection structure is provided between the iron body and the water tank. The water tank can be in a positioning state or an ejected state via the ejection structure. When the water tank is in the positioning state, it is positioned within the installation cavity. When the water tank is in the ejected state, it is wholly or partially exposed outside the installation cavity. Pressing the water tank triggers the ejection structure, allowing the water tank to switch between the positioning and ejected states. The iron body has a connector within the installation cavity, and the water tank has a through hole adapted to the connector. When the water tank is in the positioning state, the connector is inserted into the through hole to form a mating connection. When the water tank is in the ejected state, the connector disengages from the through hole.

[0005] Preferably, the iron body has a detachable box structure, the mounting cavity is opened inside the box structure, the opening of the mounting cavity is located at the front end of the box structure, the outer wall of the box structure has a mounting groove communicating with the mounting cavity, the pop-out structure is set in the mounting groove, the pop-out structure has a pushing end, the pushing end of the pop-out structure extends into the mounting cavity and abuts against the water tank.

[0006] Further optimization includes a pop-up structure comprising a base fixed to the mounting slot, a push block slidably mounted on the base, two parallel guide posts on the base, a guide hole on the push block for the guide posts to pass through, an elastic element sleeved on the guide post, the elastic element being located between the push block and the base, the front end of the push block passing through the guide groove to form a pushing end abutting against the water tank, the push block having multiple retrograde guide grooves, and a limiting rod further comprising a limiting rod, one end of the limiting rod being connected to the base, the other end of the limiting rod being hooked and slidably engaged within the guide groove, the axial direction of the limiting rod being consistent with the sliding direction of the push block, and two guide posts symmetrically distributed on both sides of the limiting rod.

[0007] Further optimization involves the guide groove comprising a first guide segment, a second guide segment, a third guide segment, and a fourth guide segment that are sequentially connected. The first and fourth guide segments are located on opposite sides of the limiting rod, with their connection point close to the axial direction of the limiting rod. The other ends of the first and fourth guide segments are inclined outwards from the limiting rod. The connection point of the second and third guide segments is also close to the axial direction of the limiting rod, with their other ends inclined outwards from the limiting rod. A first step is formed at the bottom of the connection between the second and first guide segments, making the bottom surface of the first guide segment higher than the bottom surface of the second guide segment. A second step is formed at the bottom of the connection between the third and fourth guide segments, making the bottom surface of the third guide segment higher than the bottom surface of the fourth guide segment. Two sidewall portions at the connection between the second and third guide segments respectively form a concave portion and a convex portion, which are offset from each other, with the convex portion biased towards the second guide segment.

[0008] Further optimization resulted in a smooth transition at the bottom of the second and third guide sections.

[0009] Further optimization involves forming a guide surface on the outer sidewall of the connection between the first guide segment and the second guide segment, so that the limiting rod can slide from the first guide segment into the second guide segment.

[0010] Further optimization involves the mounting groove being located on the upper surface of the box structure, with openings at the front, upper, and rear ends. A cover plate is provided at the upper end of the mounting groove, and after installation, the cover plate is flush with the upper surface of the box structure. The seat passes through the rear end of the mounting groove and is connected to the rear end of the box structure.

[0011] Further optimization involves providing a protrusion on the inner wall of the seat and a groove on the cover plate that engages with the protrusion.

[0012] The technical advantage of this utility model is that the water tank is inserted into the mounting cavity of the iron body, and a pop-out structure is provided between the iron body and the water tank. The pushing end of the pop-out structure abuts against the rear end of the water tank. When the water tank is pressed, the elastic element of the pop-out structure unlocks and extends to pop out the water tank for water filling. Attached Figure Description

Detailed Implementation

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] This utility model includes an iron body 400, an iron body 401 with an installation cavity 401, an opening at the front end of the installation cavity 401, and a water tank 402 embedded in the installation cavity 401. The water tank 402 can be inserted into or removed from the front opening. A through hole 403 is provided at the rear end of the water tank 402, which communicates with the interior of the water tank 402, allowing water to be filled into the water tank 402 through the through hole 403. The iron body 400 has a connector 423 located in the installation cavity 401. When the water tank 402 is installed in the installation cavity 401, the connector 423 is inserted into the through hole 403 and forms a connection with the through hole 403. The other end of the connector 423 is connected to the iron body 400, so that the water in the water tank 402 supplies water to the iron body 400 through the connector 423. When the water tank 402 is removed from the installation cavity 401, the connector 423 is disengaged from the through hole 403.

[0023] A pop-out structure 404 is provided between the iron body 400 and the water tank 402. The water tank 402 can be in a positioning state or a pop-out state through the pop-out structure 404. When the water tank 402 is in the positioning state, the water tank 402 is positioned inside the mounting cavity 401. When the water tank 402 is in the pop-out state, the water tank 402 is wholly or partially exposed outside the mounting cavity 401. At this time, it is convenient to manually remove the water tank 402 from the iron body 400. By pressing the water tank 402, the pop-out structure 404 is triggered, so that the water tank 402 can switch between the positioning state and the pop-out state. That is, by pressing the water tank 402, the pop-out structure 404 can be activated, so that the water tank 402 can switch between the two states.

[0024] Furthermore, the iron body 400 is provided with a detachable housing structure 424, that is, the housing structure 424 is detachable from the iron body 400, and the mounting cavity 401 is opened in the housing structure 424. The opening of the mounting cavity 401 is located at the front end of the housing structure 424. The outer wall of the housing structure 424 is provided with a mounting groove 425 communicating with the mounting cavity 401. The pop-out structure 404 is disposed in the mounting groove 425. The pop-out structure 404 has a pushing end 408. The pushing end 408 of the pop-out structure 404 extends into the mounting cavity 401 and abuts against the water tank 402. That is, the pop-out structure 404 can be detached from the iron body 400 along with the housing structure 424, which facilitates the installation, removal and maintenance of the pop-out structure 404.

[0025] Furthermore, the pop-out structure 404 includes a base 405 fixed to the mounting groove 425. The base 405 is fixed relative to the mounting groove 425. A push block 407 is slidably disposed on the base 405, meaning the push block 407 can slide along the base 405. The sliding direction of the push block 407 is a linear reciprocating movement in the back-and-forth direction. The front end of the mounting groove 425 communicates with the mounting cavity 401. The front end of the push block 407 forms a pushing end 408. The pushing end 408 passes through the front end of the mounting groove 425 and extends into the mounting cavity 401, then abuts against the back of the water tank 402. The base 405 is provided with two parallel guide posts 409, which are arranged along the pushing direction. The push block 407 has a guide hole 410 for the guide posts 409 to pass through, allowing the push block 407 to reciprocate along the guide posts 409, preventing the push block 407 from deviating during movement. An elastic element 411, such as a spring, is fitted onto the pusher 409. The elastic element 411 is located between the pusher 407 and the seat 405, allowing the pusher 407 to slide elastically. The pusher 407 has multiple retracing guide grooves 412. The pop-out structure 404 also includes a limiting rod 422, which is a rod-shaped body with a certain elastic deformation. One end of the limiting rod 422 is connected to the seat 405, and the seat 405 has an installation hole. The end of the limiting rod 422 is bent and inserted into the installation hole to form a connection with the seat 405. The other end of the limiting rod 422 is also bent and inserted into the guide groove 412 to form a sliding fit with the guide groove 412. That is, as the pusher 407 moves back and forth, the end of the limiting rod 422 can move along the guide groove 412. With the cooperation of the elastic element 411, the pusher 407 can slide elastically relative to the seat 405. The axial direction of the limiting rod 422 is consistent with the sliding direction of the push block 407. Two guide posts 409 are symmetrically distributed on both sides of the limiting rod 422, making the sliding of the push block 407 more stable.

[0026] Furthermore, the guide groove 412 includes a first guide section 413, a second guide section 414, a third guide section 415, and a fourth guide section 416 that are sequentially connected and terminated. These four sections form a closed groove path. The first guide section 413 and the fourth guide section 416 are located on both sides below the limiting rod 422, and the connection point between the first guide section 413 and the fourth guide section 416 is close to or located on the axial direction of the limiting rod 422. The other ends of the first guide segment 413 and the fourth guide segment 416 are inclined outwards to both sides with the limiting rod 422 as the center. The connection point of the second guide segment 414 and the third guide segment 415 is close to or located on the axial direction of the limiting rod 422. The other ends of the second guide segment 414 and the third guide segment 415 are inclined outwards with the limiting rod 422 as the center. The end of the limiting rod 422 slides sequentially along the first guide segment 413, the second guide segment 414, the third guide segment 415 and the fourth guide segment 416, and finally returns to the connection point of the first guide segment 413 and the fourth guide segment 416.When the end of the limiting rod 422 is located at the connection point of the first guide section 413 and the fourth guide section 416, under the elastic force of the elastic element 411, the push block 407 moves away from the seat 405, that is, the pushing end 408 of the push block 407 moves forward. The water tank 402 is pushed by the pushing end 408 of the push block 407 and is in the pop-out state. Then, the water tank 402 is pressed, that is, the pushing end 408 is pressed, causing the push block 407 to slide backward, that is, the end of the connecting rod slides along the first guide section 413. When the end of the connecting rod slides to the connection point of the first guide section 413 and the second guide section 414, it enters the second guide section 414 and slides along the second guide section 414 to the connection point of the second guide section 414 and the third guide section 415. At this time, the elastic element 411 is in the compressed state, and the connecting rod hooks into the recess 419 at the connection point. At this time, the push block 407 has moved to the rear, that is, the push block 407 When the push end 408 is in a retracted state, the water tank 402 is embedded in the mounting cavity 401. When the water tank 402 is pressed again, the water tank 402 pushes the push block 407 backward. The recess 419 of the push block 407 separates from the end of the connecting rod, while the protrusion 420 at the connection point presses against the end of the connecting rod. The push block 407 continues to move backward, and the end of the connecting rod slides along the protrusion 420 into the third guide section 415 until it slides to the connection point of the third guide section 415 and the fourth guide section 416. At this time, the push block 407 has moved backward to its limit position. Finally, the force of pressing the water tank 402 is released, and the push block 407 slides forward under the restoring force of the elastic element 411. At this time, the end of the connecting rod enters the fourth guide section 416, and the end of the connecting rod moves forward along the fourth guide section 416. Finally, it slides to the connection point of the fourth guide section 416 and the first guide section 413. At this time, the water tank 402 is in the pop-out state, and this cycle continues.

[0027] Of course, in this application, the push block 407 actually slides back and forth, while the connecting rod is stationary relative to the push block 407. However, for ease of description and understanding, this application specifically describes the end of the connecting rod as sliding along the guide groove 412.

[0028] Additionally, it should be noted that after the water tank 402 is installed into the mounting cavity 401, the connector 423 and the through hole 403 form a mating, which provides a certain degree of fixation between the water tank 402 and the iron body 400, preventing the water tank 402 from detaching from the mounting cavity 401 during the use of the iron body 400; or, a certain tight fit is formed between the outer peripheral wall of the water tank 402 and the inner wall of the mounting cavity 401, which can also prevent the water tank 402 from shifting or detaching from the mounting cavity 401.

[0029] Furthermore, a first step 417 is formed at the bottom of the connection between the second guide segment 414 and the first guide segment 413, so that the bottom surface of the first guide segment 413 is higher than the bottom surface of the second guide segment 414. A second step 418 is formed at the bottom of the connection between the third guide segment 415 and the fourth guide segment 416, so that the bottom surface of the third guide segment 415 is higher than the bottom surface of the fourth guide segment 416. In this way, when the end of the connecting rod slides along the first guide segment 413, the second guide segment 414, the third guide segment 415 and the fourth guide segment 416 in sequence, it can slide smoothly without jamming.

[0030] It should be noted that the two sidewall portions at the connection between the second guide segment 414 and the third guide segment 415 respectively form a recess 419 and a protrusion 420. The recess 419 and the protrusion 420 are misaligned, with the protrusion 420 biased towards the second guide segment 414. Thus, when the push block 407 slides relative to the end of the connecting rod, as the end of the connecting rod slides from the connection point between the second guide segment 414 and the third guide segment 415 toward the third guide segment 415 (i.e., when the push block 407 begins to slide backward), the end of the connecting rod will abut against the protrusion 420, causing the end of the connecting rod to naturally... The connecting rod slides along the protrusion 420 to the third guide section 415, thus serving a guiding function. This allows the end of the connecting rod to slide sequentially along the second guide section 414, the connection point of the second guide section 414 and the third guide section 415, and the third guide section 415. Similarly, the connection point of the first guide section 413 and the fourth guide section 416 is also configured in the same way, that is, the two sidewall portions of the connection point also form a misaligned concave portion 419 and a protrusion 420, so that the connecting rod can smoothly slide from the connection point of the first guide section 413 and the fourth guide section 416 to the first guide section 413.

[0031] Furthermore, the bottoms of the second guide section 414 and the third guide section 415 form a smooth transition. Since the path of the second guide section 414 is shorter, this facilitates the end of the connecting rod to slide along the second guide section 414 to the third guide section 415.

[0032] Furthermore, a guide surface 421 is formed on the outer sidewall of the connection between the first guide section 413 and the second guide section 414 so as to guide the limiting rod 422 to slide from the first guide section 413 into the second guide section 414.

[0033] Furthermore, the mounting groove 425 is located on the upper surface of the housing structure 424. The front end, upper end and rear end of the mounting groove 425 are all open. The upper end of the mounting groove 425 is provided with a cover plate 426. After the cover plate 426 is installed, it is flush with the upper surface of the housing structure 424. The base 405 passes through the rear end of the mounting groove 425 and is connected to the rear end of the housing structure 424. In this way, the pop-out structure 404 can be hidden and installed on the housing structure 424, which makes it easier for the housing structure 424 to be installed on the iron body, thereby improving the space utilization rate.

[0034] Furthermore, the inner wall of the seat 405 is provided with a protrusion 406, and the cover plate 426 is provided with a groove 427 that engages with the protrusion 406. In this way, the cover plate 426 can be snapped onto the seat 405, which not only simplifies the structure but also makes it easy to install and remove the cover plate 426.

[0035] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
