Description

Technical Field

[0001] The invention relates to the field of cooking devices, and in particular to a cooking device having a water tank pushing out and retracting structure. Background Art

[0002] Cooking devices with steaming functions are generally provided with water tanks, such as electric steamers, steam-bake-in-one machines, etc. Currently, one of the main trends in steaming cooking devices on the market is that the water tank is placed on part of the control panel. For the overall aesthetics of the product, the water tank is generally embedded inside the control panel. When taking the water tank, the water tank needs to be pressed backwards, and the water tank pops out forward. At this time, the user can take the water tank or add water to the water tank. For example, the Chinese utility model patent with patent number ZL201220591711.7 (authorization announcement number CN202979507U) discloses a water tank push-out structure for household appliances.

[0003] In the prior art, the water tank is generally pushed out by a push rod, a cam and other structures. For example, the Chinese utility model patent with patent number ZL201220591711.7 (authorization announcement number CN202979507U) discloses a water tank push-out structure of a household appliance, including a water tank slidably connected to the housing of the household appliance, and also includes: a driving component for driving the water tank to slide relative to the housing of the household appliance, the driving component is arranged in the housing of the household appliance; a control component for controlling the driving component, the control component is electrically connected to the driving component, and the control component is arranged on the housing of the household appliance. The Chinese utility model patent with patent number ZL201720543211.9 (authorization announcement number CN206955070U) discloses a water tank push-out device, including a housing and a water tank slidably connected to the front end of the housing, a micro switch is arranged at the end of the housing, an eccentric wheel driven by a motor is arranged between the water tank and the micro switch, a protrusion is arranged on the eccentric wheel, and the motor drives the eccentric wheel to rotate. When the protrusion of the eccentric wheel abuts against the water tank, the eccentric wheel pushes the water tank to slide out relative to the housing, and when the protrusion of the eccentric wheel abuts against the micro switch, the micro switch controls the motor to stop rotating. This method has the problem of unstable pushing and retracting of the water tank, and there is a risk of the water tank sliding off when pushing the water tank out. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a water tank pushing and retracting structure with a smooth water tank pushing and retracting action in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a water tank pushing and retracting structure with a stable water tank pushing and retracting action and convenient water tank taking, in view of the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a water tank pushing-out and retracting structure for preventing the water tank from sliding down in view of the prior art.

[0007] The fourth technical problem to be solved by the present invention is to provide a water tank pushing and retracting structure which does not require power supply and is easy to push out in view of the prior art.

[0008] The fifth technical problem to be solved by the present invention is to provide a water tank pushing-out and retracting structure which can effectively ensure that the water tank is retracted into place in view of the prior art.

[0009] The sixth technical problem to be solved by the present invention is to provide a cooking device with the above-mentioned water tank pushing-out and retracting structure in view of the prior art.

[0010] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a water tank pushing out and retracting structure, including a water tank assembly, the water tank assembly including a water tank and a water tank seat for accommodating the water tank, the water tank seat having an opening for the water tank to enter and exit, the above-mentioned water tank can be relatively slidably connected to the water tank seat and can be extended from the opening of the water tank seat, and is characterized in that the water tank seat is provided with a slide groove extending along the direction of entry and exit of the water tank, a slide bar that can slide back and forth along the slide groove is embedded in the slide groove, and the slide bar is detachably connected to the above-mentioned water tank.

[0011] In order to enable the slide bar to slide back and forth along the slide groove to better guide the water tank to be pushed out and retracted along the water tank seat, preferably, the slide bar is arranged on the rear side of the water tank along the water tank pushing direction, and the front end of the slide bar is detachably connected to the tail of the water tank.

[0012] The detachable connection between the slide bar and the water tank can be implemented in a variety of specific ways, such as a magnetic connection or a snap connection between the front end of the slide bar and the rear end of the water tank. In order to form a stable connection between the slide bar and the water tank and also facilitate the user to take the water tank, preferably, the front end of the slide bar is snap-connected to the rear end of the water tank.

[0013] Furthermore, the front end of the slide bar is provided with a buckle block, and the rear end of the water tank is provided with a buckle groove for the buckle block to be buckled into.

[0014] Furthermore, an elastic pressure bead is provided on the buckle block of the slide bar. When the buckle block is inserted into the buckle groove, the elastic pressure bead is in a compressed and retracted state and has a tendency to pop outward. In this way, when the buckle block is inserted into the buckle groove, the elastic pressure bead is compressed and accumulates potential energy, thereby ensuring that the buckle block can be firmly buckled in the buckle groove, effectively preventing the water tank from falling out of the water tank seat when it is not removed.

[0015] There are multiple specific connection structures between the above-mentioned buckle block and the buckle groove, and one preferred implementation method is: there are two elastic pressure beads and they are respectively arranged on both sides of the above-mentioned buckle block in a direction perpendicular to the water tank inlet and outlet direction, and guide blocks are respectively convexly provided on the groove surfaces corresponding to each elastic pressure bead in the above-mentioned buckle groove, and each guide block includes a first guide inclined surface, a transition surface and a first limiting inclined surface in sequence on the side surface along the buckle block snap-in direction, wherein the first guide inclined surface is inclined inward from back to front relative to the groove surface where it is located, and the first limiting inclined surface is inclined outward from back to front relative to the groove surface where it is located, and the transition surface is connected between the first guide inclined surface and the first limiting inclined surface, and when the buckle block is snapped into or out of the above-mentioned buckle groove, each elastic pressure bead can slide along the side surface of the corresponding guide block, and be compressed and limited in the angle formed by the corresponding first limiting inclined surface and the groove surface of the buckle groove, or slide out of the buckle groove along the guide inclined surface. This facilitates the buckle block to snap into and snap out of the buckle groove under the action of external force (thrust and pull acting on the water tank), and enables the water tank to be firmly connected to the slide bar in the installed state.

[0016] Furthermore, in each of the guide blocks, the angle formed by the first guide slope and the groove surface of the buckle groove where it is located is smaller than the angle formed by the first limiting slope and the groove surface of the buckle groove, and the transition surface is parallel to the groove surface of the buckle groove where it is located.

[0017] Another preferred implementation of the specific connection structure between the above-mentioned snap block and the snap groove is: the elastic pressure beads are respectively arranged on both sides of the above-mentioned snap block along a direction perpendicular to the water tank inlet and outlet direction, and the left and right groove surfaces of the above-mentioned snap groove continuously include a second guide slope, a second limiting slope and a snap surface along the snap-in direction of the snap block, wherein each second guide slope is inclined outward from front to back, and each second guide slope is inclined inward from front to back, and the snap surface is a plane, and when each elastic pressure bead is snapped into the corresponding snap groove, each elastic pressure bead is offset against the corresponding snap surface.

[0018] Furthermore, the volume of the buckle slot matches the volume of the buckle block, thereby making the buckle connection between the buckle block and the buckle slot more stable.

[0019] Furthermore, the water tank and the water tank seat are both box-shaped, wherein the front end of the water tank seat is open, and the water tank is slidably mounted in the water tank seat along the front-back direction, and the above-mentioned slide groove is provided on the inner top surface of the water tank seat along the front-back direction. That is, by arranging the slide bar and the slide groove on the upper part of the water tank seat to guide the water tank to slide forward and backward along the water tank seat, the slide bar has better stability and no cantilever state, so that the pushing and retracting actions of the water tank can be smoother. In addition, it is more concealed and is not easy for users to touch when cleaning the inside of the water tank seat.

[0020] Furthermore, the slide bar is provided with a tooth surface along its length direction, and also includes a rebound component and a guide locking mechanism. The rebound component includes a first gear, a coil spring and a coil spring seat for installing the coil spring. The coil spring seat includes a rotating wheel for winding the coil spring. The first gear is coaxially arranged with the rotating wheel and meshes with the tooth surface of the slide bar. A sliding gap is left between the rear end of the slide bar and the corresponding end of the slide slot. When the water tank is open, the water tank is pressed in the direction of retracting the water tank. The slide bar moves along the slide slot in the direction of retracting the water tank and is locked by the guide locking mechanism, and the coil spring accumulates potential energy. When the water tank is closed, the water tank is pressed in the direction of retracting the water tank. The coil spring releases potential energy, the locking component is unlocked, and the water tank is pushed out. The meshing action of the first gear and the slide bar transmits the force applied by the user to the water tank and the movement generated by the water tank to the slide bar, and then transmits it to the first gear through the slide bar, so that the coil spring accumulates or releases potential energy, thereby realizing the semi-automatic pushing out of the water tank, which is not only convenient for pushing out the water tank, but also does not require the use of power supply, has a simple structure, and saves energy.

[0021] Furthermore, it also includes a one-way damping gear meshing with the tooth surface of the slide bar and having no damping in the direction of retracting the water tank. The one-way damping gear cooperates with the slide bar to control the slide bar ejection speed, that is, the water tank ejection speed, making the water tank ejection action more stable, while reducing the resistance to be overcome in the direction of pushing the water tank in, and improving the user's feel of pushing the water tank in.

[0022] Furthermore, the guide locking mechanism includes a first guide and a second guide, wherein the first guide is linked with the water tank and the water tank seat, and the second guide is linked with the water tank seat. When the water tank moves in and out relative to the water tank seat, the first guide and the second guide can slide relative to each other, and when the water tank is closed, the first guide and the second guide can be relatively locked. The guide locking mechanism can guide the movement of the slide bar relative to the slide slot, so that the slide bar can better move along the preset track, and can overcome the forward thrust of the coil spring on the slide bar to lock the slide bar.

[0023] Furthermore, the second guide member is arranged on the above-mentioned slide bar, and one end of the first guide member is slidably connected to the second guide member, and the other end is connected to the water tank seat.

[0024] Furthermore, the second guide member is a guide groove arranged on the above-mentioned slide bar, and the above-mentioned first guide member is a guide slide bar, one end of which is pivotally connected to the water tank seat, and the other end can slide along the above-mentioned guide groove as the slide bar moves.

[0025] Furthermore, the guide groove is arranged along the length direction of the slide bar, and includes an unlocking area and a locking area from back to front, wherein the locking area includes a guide section connected end to end, a locking guide section, a locking buffer section and a locking position from back to front, the guide section is formed by shrinking the unlocking area forward and is used to guide the guide slide bar into the locking guide section, while the locking guide section is used to guide the guide slide bar into the locking buffer section, and the locking buffer section is used to buffer the guide slide bar for reversing and guiding it into the above-mentioned locking position for locking.

[0026] Furthermore, it also includes a locking guide slope and a locking introduction slope. The front end of the above-mentioned locking buffer section is closed and the rear end is open. The above-mentioned locking guide slope is arranged between the locking guide section and the rear end opening of the locking buffer section and is used to guide the guide slide into the locking buffer section. The above-mentioned locking introduction slope is continuously arranged with the above-mentioned locking position. The rear end opening of the above-mentioned locking buffer section is opposite to the introduction slope in front and back and staggered with the above-mentioned locking position. The above-mentioned introduction slope is used to guide the guide slide into the above-mentioned locking position.

[0027] Furthermore, it also includes an unlocking buffer section, an unlocking guide slope and an unlocking guide section. The unlocking buffer section is closed at the front end and open at the rear end. The unlocking guide slope is arranged opposite to the locking position and continuously with the open end of the unlocking buffer section. The unlocking guide slope is used to guide the guide slide rod into the unlocking buffer section. The upper end of the unlocking guide section is connected to the rear end opening of the unlocking buffer section and is used to guide the guide slide rod to the guide section.

[0028] Furthermore, it also includes an unlocking guide slope, the unlocking guide section extends along the length direction of the unlocking buffer section, and the guide section is staggered with the unlocking guide section, and the unlocking guide slope is continuously arranged between the unlocking guide section and the guide section and tilted toward the guide section from front to back.

[0030] Furthermore, it also includes a positioning mechanism for detecting the position of the water tank. The positioning mechanism is arranged on the water tank seat and located at the rear side of the water tank. It includes a micro switch, a trigger member and a reset spring. The trigger member is slidably arranged on the water tank seat along the direction of entry and exit of the water tank. One end of the reset spring is installed on the trigger member, and the other end is installed on the water tank seat. When the water tank is not placed or opened, the trigger end of the trigger member abuts against the micro switch, the micro switch is closed, and the reset spring is in a natural state; when the water tank is retracted, force is transmitted to the contact end of the trigger member to make the trigger member slide. When the water tank is retracted into place, the trigger end of the trigger member is disengaged from the micro switch, the micro switch is opened, and the reset spring is compressed to store energy. The positioning mechanism can detect the placement position of the water tank, thereby avoiding the phenomenon of failure to pump water or water leakage caused by incorrect placement of the water tank.

[0031] Furthermore, the trigger member is a rod extending along the direction of the water tank inlet and outlet, and the above-mentioned micro switch is arranged on one side of the trigger member along the direction perpendicular to the direction of the water tank inlet and outlet. The front end of the trigger member is the above-mentioned contact end, and the rear end is bent toward the micro switch side and its end forms the above-mentioned trigger end.

[0034] Furthermore, first guide ribs are protruded on the left and right inner side surfaces of the front end of the water tank seat along the front-to-back direction, while second guide ribs are protruded on the left and right inner side surfaces of the rear end of the water tank seat along the front-to-back direction.

[0035] Furthermore, each of the first guide ribs and the second guide ribs are respectively arranged on the upper part of the inner cavity of the water tank seat, and a third guide rib is protruded on the inner top surface of the water tank seat along the front-to-back direction, and a fourth guide rib is protruded on the bottom surface of the water tank along the front-to-back direction.

[0036] Furthermore, the height of each of the first guide ribs is higher than the height of each of the second guide ribs.

[0037] Furthermore, along the cross section where each of the first guide ribs is located, the gap between each of the first guide ribs and the corresponding outer side surface of the water tank is D1, and the gap between the outer side surface of the water tank portion behind each of the first guide ribs and the inner side surface of the water tank seat is D2. A control panel is also included, the above-mentioned water tank assembly is arranged on the rear side of the control panel, and the control panel is provided with a water tank opening for the water tank to extend forward, and a water tank panel is provided on the front end surface of the water tank. When the water tank is closed, the water tank panel is embedded in the above-mentioned water tank opening, and the gap between the left and right side edges of the water tank panel and the corresponding edge of the water tank opening is D3, then D3>D2>D1. By reasonably designing the sizes of the above-mentioned D1, D2 and D3, the water tank panel can be prevented from being stuck in the water tank opening of the control panel, and the phenomenon of jamming during the process of pushing out the water tank can be avoided. At the same time, the water outlet of the water tank and the water outlet joint of the water tank can be prevented from being offset during the process of pushing in the water tank, and the phenomenon of failure to pump water or water leakage during use can be avoided.

[0038] Furthermore, a water level display window is provided on the water tank panel, so that the user can directly observe the water level in the water tank through the water level display window, thereby adding water to the water tank in time.

[0039] Furthermore, a water filling port is provided on the top wall of the water tank, and a water filling cap is provided on the water filling port, so that it is convenient for users to add water to the water tank.

[0083] like Figures 1 to 22 As shown, a cooking device includes a water tank push-out and retracting structure, the water tank push-out and retracting structure includes a water tank assembly 1, and the water tank assembly 1 includes a water tank 11 and a water tank seat 12 for accommodating the water tank 11. In this embodiment, the water tank 11 and the water tank seat 12 are both square in shape, and the front end of the water tank seat 12 is open, and the water tank 11 is slidably installed in the water tank seat 12. Further, the water tank push-out and retracting structure also includes a control panel 2, the water tank assembly 1 is arranged at the rear side of the control panel 2, and the control panel 2 is provided with a water tank port 21 for the water tank 11 to extend forward, and the front end surface of the water tank 11 is provided with a water tank panel 13, and when the water tank 11 is closed, the water tank panel 13 is embedded in the water tank port 21.

[0084] In this embodiment, the water tank seat 12 includes an upper cover 121 and a lower cover 122, and is formed by buckling the upper cover 121 and the lower cover 122. Further, in this embodiment, the left and right inner side surfaces of the front end of the water tank seat 12 are respectively provided with first guide ribs 1211 along the front-to-back direction, and the left and right inner side surfaces of the rear end of the water tank seat 12 are respectively provided with second guide ribs 1212 along the front-to-back direction. Since the water tank 11 in this embodiment is relatively long, the first and second guide ribs 1211, 1212 can be provided to enable the water tank 11 to slide smoothly forward and backward relative to the water tank seat 12. Furthermore, each of the first guide ribs 1211 and the second guide ribs 1212 are respectively arranged at the upper part of the inner cavity of the water tank seat 12, and at the same time, a third guide rib 1213 is convexly arranged on the inner top surface of the water tank seat 12 in the front-to-back direction, and a fourth guide rib 111 is convexly arranged on the bottom surface of the water tank 11 in the front-to-back direction, so that the first and second guide ribs 1211, 1212 located at the upper part of the inner cavity of the water tank seat 12 and the third guide rib 1213 located at the lower part of the water tank seat 12 can make the water tank 11 move back and forth more smoothly relative to the water tank seat 12. Preferably, the height of each of the first guide ribs 1211 is higher than the height of each of the second guide ribs 1212, so that the center of gravity of the rear side of the water tank 11 can be more stable during the process of pushing the water tank 11 along the water tank seat 12, so that the pushing action of the water tank 11 can be more stable.

[0085] Furthermore, along the cross section where each of the first guide ribs 1211 is located, the gap between each of the first guide ribs 1211 and the corresponding outer side surface of the water tank 11 is D1, and the gap between the outer side surface of the water tank 11 portion behind each of the first guide ribs 1211 and the inner side surface of the water tank seat 12 is D2, and the gap between the left and right side edges of the water tank panel 13 and the corresponding edge of the water tank opening 21 is D3, then D3>D2>D1. By reasonably designing the sizes of D1, D2 and D3, the water tank panel 13 can be prevented from getting stuck in the water tank opening 21 of the control panel 2, and the jamming phenomenon can be avoided during the process of pushing out the water tank 11. At the same time, the water outlet of the water tank 11 and the water outlet connector of the water tank 11 can be prevented from being offset during the process of pushing in the water tank 11, and the phenomenon of failing to pump water or leaking water during use can be avoided.

[0086] In addition, in this embodiment, a transparent water level display window 131 is vertically arranged on the water tank panel 13, so that the user can directly observe the water level in the water tank 11 through the water level display window 131, so as to add water to the water tank 11 in time. A water injection port 112 is provided on the top wall of the water tank 11, and a water injection cover 113 is provided on the water injection port 112. Further, the water tank 11 includes a water box 110 with a top opening and a top cover 114 that can cover the opening of the water box 110. The water injection port 112 is arranged at one end of the top cover 114 along its length direction, and when the top cover 114 is covered and connected with the water box 110, the two ends of the top cover 114 along its length direction can be interchanged. In this way, the user can make the water injection port 112 located at the front end or the rear end of the water tank 11 according to the usage habits, and when the water injection port 112 is located at the front end of the water tank 11, the user can fill water into the water tank 11 without taking out the water tank 11. In addition, a sealing ring 115 is sandwiched between the top cover 114 and the edge of the opening of the water box 110, so as to prevent water from leaking from the joint between the top cover 114 and the opening of the water box 110 after the water tank 11 is filled with water.

[0087] Furthermore, the water tank push-out and retracting structure further comprises a slide bar 3, and a slide groove 120 is provided in the water tank seat 12 along the front-to-back direction, the slide bar 3 is embedded in the slide groove 120 and can slide back and forth along the slide groove 120, and the slide bar 3 is detachably connected to the water tank 11. Thus, the water tank 11 can slide along the slide groove 120 smoothly along with the slide bar 3, so that the push-out and retracting actions of the water tank 11 are smooth, and the water tank 11 and the slide bar 3 are detachably connected, which not only facilitates the taking of the water tank 11, but also prevents the water tank 11 from sliding off the water tank seat 12 when the cooking device is placed at an angle. Preferably, in this embodiment, the slide groove 120 is provided on the inner top surface of the water tank seat 12 along the front-to-back direction, that is, by providing the slide bar 3 and the slide groove 120 on the upper part of the water tank seat 12 to guide the water tank 11 to slide forward and backward along the water tank seat 12, the slide bar 3 has better stability and no cantilever state, so that the push-out and retracting actions of the water tank 11 can be more stable. Moreover, the concealment is better, and the user is not easy to touch when cleaning the inside of the water tank seat 12. Specifically, in this embodiment, the rear end of the upper cover 121 of the water tank 11 is provided with the above-mentioned slide groove 120 along its length direction.

[0088] In order to make the sliding back and forth of the slide bar 3 along the slide groove 120 better guide the pushing out and retracting action of the water tank 11 along the water tank seat 12, in this embodiment, the slide bar 3 is arranged at the rear side of the water tank 11 along the pushing out direction of the water tank 11, and the front end of the slide bar 3 is detachably connected to the tail of the water tank 11. The detachable connection between the slide bar 3 and the water tank 11 can be realized in a variety of specific ways, such as magnetic connection or snap connection between the front end of the slide bar 3 and the tail of the water tank 11, etc. In order to make the slide bar 3 and the water tank 11 form a stable connection and also facilitate the user to take the water tank 11, in this embodiment, the front end of the slide bar 3 is snap-connected to the tail of the water tank 11. Specifically, the front end of the slide bar 3 has a snap block 31, and the tail of the water tank 11 is provided with a snap groove 4 for the snap block 31 to snap into.

[0089] Furthermore, an elastic pressure bead 311 is provided on the buckle block 31 of the slide bar 3. When the buckle block 31 is inserted into the buckle groove 4, the elastic pressure bead 311 is compressed and retracted and has a tendency to pop outward. In this way, when the buckle block 31 is inserted into the buckle groove 4, the elastic pressure bead 311 is compressed and accumulates potential energy, thereby ensuring that the buckle block 31 can be firmly buckled in the buckle groove 4, effectively preventing the water tank 11 from falling out of the water tank seat 12 when the water tank 11 is not removed. Furthermore, in the present embodiment, there are two elastic pressing beads 311, which are respectively arranged on the left and right outer sides of the above-mentioned buckle block 31, and the left and right groove walls of the above-mentioned buckle groove 4 are respectively provided with guide blocks 41, and each guide block 41 includes a first guide inclined surface 411, a transition surface 412 and a first limiting inclined surface 413 on the side along the buckle block 31 snap-in direction, wherein the first guide inclined surface 411 is inclined inward from back to front relative to the groove surface where it is located, and the first limiting inclined surface 413 is inclined outward from back to front relative to the groove surface where it is located, and the transition surface 412 is connected between the first guide inclined surface 411 and the first limiting inclined surface 413. When the buckle block 31 is snapped into or out of the above-mentioned buckle groove 4, each elastic pressing bead 311 can slide along the side of the corresponding guide block 41, and be compressed and limited in the angle formed by the corresponding first limiting inclined surface 413 and the groove surface of the buckle groove 4, or slide out of the buckle groove 4 along the guide inclined surface. This facilitates the buckle block 31 to be inserted into and removed from the buckle slot 4 under the action of external force (thrust and pull acting on the water tank 11), and the water tank 11 can be firmly connected to the slide bar 3 in the installed state. Preferably, in each guide block 41, the angle formed by the first guide inclined surface 411 and the groove surface of the buckle slot 4 where it is located is smaller than the angle formed by the first limiting inclined surface 413 and the groove surface of the buckle slot 4, and the transition surface 412 is parallel to the groove surface of the buckle slot 4 where it is located, so that the buckle block 31 can be better introduced into and out of the buckle slot 4, and the buckle block 31 can be better limited in the buckle slot 4. In this embodiment, the volume size of the above-mentioned buckle block 31 matches the volume size of the above-mentioned buckle slot 4, so that the buckle connection between the buckle block 31 and the buckle slot 4 can be more stable.

[0090] Further, in this embodiment, the front end of the slide bar 3 extends vertically upward to form an extension block 310, and the front upper end of the extension block 310 extends forward to form the buckle block 31. A tooth surface 32 is provided on one side of the top surface of the slide bar 3 in the extending length direction. Further, the water tank push-out and retracting structure in this embodiment also includes a rebound component 5 and a guide locking mechanism 6. The rebound component 5 includes a first gear 51, a coil spring 52, and a coil spring seat 53 for installing the coil spring 52. The coil spring seat 53 includes a rotating wheel 531 for winding the coil spring 52. The first gear 51 is coaxially arranged with the rotating wheel 531 and meshes with the tooth surface 32 of the slide bar 3. A sliding gap is left between the rear end of the slide bar 3 and the corresponding end of the slide groove 120. When the water tank 11 is open, the water tank 11 is pressed in the direction of the water tank 11 being retracted, and the slide bar 3 moves into position along the slide groove 120 in the direction of the water tank 11 being retracted and locked by the guide locking mechanism 6, and the coil spring 52 accumulates potential energy; when the water tank 11 is closed, the water tank 11 is pressed in the direction of the water tank 11 being retracted, and the coil spring 52 releases potential energy, and the guide locking mechanism 6 is unlocked, and the water tank 11 is pushed out. It can be seen that the meshing action of the first gear 51 and the slide bar 3 in this embodiment transmits the force applied by the user to the water tank 11 and the movement generated by the water tank 11 to the slide bar 3, and then transmits it to the first gear 51 through the slide bar 3, so that the coil spring 52 accumulates or releases potential energy, thereby realizing the semi-automatic pushing out of the water tank 11, which is not only convenient for pushing out the water tank 11, but also does not require the use of a power supply, has a simple structure, and saves energy. Furthermore, it also includes a one-way damping gear 50 that meshes with the tooth surface 32 of the above-mentioned slide bar 3 and has no damping in the retraction direction of the water tank 11. The one-way damping gear 50 is arranged after the above-mentioned rebound component 5, so that the pop-up speed of the slide bar 3 can be controlled through the cooperation of the one-way damping gear 50 and the slide bar 3, that is, the pushing speed of the water tank 11 can be controlled, so that the pushing action of the water tank 11 is smoother, and at the same time, the resistance to be overcome in the pushing direction of the water tank can be reduced, thereby improving the user's feel of pushing the water tank 11.

[0091] The guide locking mechanism 6 includes a first guide and a second guide, wherein the first guide is linked with the water tank 11 and the water tank seat 12, and the second guide is linked with the water tank seat 12. When the water tank 11 moves in and out relative to the water tank seat 12, the first guide and the second guide can slide relative to each other, and when the water tank 11 is closed, the first guide and the second guide can be relatively locked. The guide locking mechanism 6 can guide the movement of the slide bar 3 relative to the slide groove 120, so that the slide bar 3 can better move along the preset trajectory, and can overcome the forward thrust of the coil spring 52 on the slide bar 3 and lock the slide bar 3. Preferably, in this embodiment, the second guide is arranged on the slide bar 3, and one end of the first guide is slidably connected to the second guide, and the other end is connected to the water tank seat 12. Further, preferably, the second guide member is a guide groove 61 provided on the slide bar 3, and the first guide member is a guide slide bar 62, one end of the guide slide bar 62 is pivotally connected to the top wall of the upper cover 121 of the water tank seat 12, and the other end can slide along the guide groove 61 with the movement of the slide bar 3. Specifically, in this embodiment, the guide groove 61 is provided on the top surface of the slide bar 3 along the length direction of the slide bar 3 and is arranged in parallel with the tooth surface 32, and the guide slide bar 62 extends horizontally, and its upper and lower ends are respectively bent vertically, and the upper end is pivotally connected to the upper cover 121 of the water tank seat 12, and the lower end is embedded in the guide groove 61.

[0092] The above-mentioned guide groove 61 includes an unlocking area 61a and a locking area 61b from back to front, wherein the locking area 61b includes an unlocking area 61a, a guide section 611, a locking guide section 612, a locking buffer section 613 and a locking position 614 connected end to end from back to front, wherein the guide section 611 is formed by shrinking the unlocking area 61a forward and is used to guide the guide slide 62 into the locking guide section 612, and the locking guide section 612 is used to guide the guide slide 62 into the locking buffer section 613, and the locking buffer section 613 is used to buffer the reversal of the guide slide 62 and guide it into the above-mentioned locking position 614 for locking. Furthermore, it also includes a locking guide bevel 615 and a locking introduction bevel 616. The above-mentioned locking buffer section 613 is located on the front groove wall of the guide groove 61, with its front end closed and the rear end open. The above-mentioned locking guide bevel 615 is arranged between the locking guide section 612 and the rear end opening of the locking buffer section 613 and is used to introduce the guide slide bar 62 into the locking buffer section 613, and the above-mentioned locking introduction bevel 616 is continuously arranged with the above-mentioned locking position 614. The rear end opening of the above-mentioned locking buffer section 613 is opposite to the locking introduction bevel 616 front and back and staggered with the above-mentioned locking position 614. The above-mentioned locking introduction bevel 616 is used to introduce the guide slide bar 62 into the above-mentioned locking position 614. Furthermore, it also includes an unlocking buffer section 617, an unlocking guide slope 618 and an unlocking guide section 619. The unlocking buffer section 617 is located on the front groove wall of the guide groove 61 and is arranged in parallel with the locking buffer section 613, with its front end closed and the rear end open. The unlocking guide slope 618 is arranged opposite to the locking position 614 and is continuously arranged with the open end of the unlocking buffer section 617, and the unlocking guide slope 610 is used to guide the guide slide rod 62 into the unlocking buffer section 617. The upper end of the unlocking guide section 619 is connected to the rear end opening of the unlocking buffer section 617 and is used to guide the guide slide rod 62 to the guide section 611. In this embodiment, a guide protrusion 63 is protruded from the front end of the guide groove 61 on the front side of the guide section 611. The overall shape of the guide protrusion 63 is triangular, and its left and right side surfaces and the corresponding groove walls of the guide groove 61 respectively form the locking guide section 612 and the unlocking guide section 619. At the same time, the left side of the front side surface is bent backward to form a V-shaped groove, thereby forming a locking position 614 for the lower end of the guide slide rod 62 to be snapped and limited on the front side surface and the locking guide inclined surface 616.

[0093] When the water tank 11 is retracted, the water tank 11 is pushed backward, and the slide bar 3 moves backward along the slide groove 120. The lower end of the guide slide bar 62 slides from the unlocking area 61a into the guide section 611. When sliding to the locking guide section 612, the guide slide bar 62 deflects and slides into the locking buffer section 613 under the action of the locking guide inclined surface 615. At this time, the slide bar 3 slides into place, and the guide slide bar 62 overcomes the sliding inertia in the locking buffer section 613 and is guided into the locking position 614 under the action of the locking guide inclined surface 616 to lock, thereby locking the slide bar 3. When the water tank is pushed out, the water tank panel 13 of the water tank is pressed backwards, and the lower end of the guide slide bar 62 enters the unlocking buffer section 617 from the locking position 614 under the action of the unlocking guide inclined surface 618, and then the slide bar 3 slides forward under the action of the rebound force of the coil spring 52, at which time the lower end of the guide slide bar 62 slides backward out of the unlocking buffer section 617 and slides into the guide section 611 through the unlocking guide section 619, and finally slides into the unlocking area 61a, thereby unlocking the slide bar 3, and the user can take the water tank. In this embodiment, the locking area 61b is located at the front end of the guide groove 61, and the unlocking area 61a extends from the rear end of the guide section 611 to the rear end of the guide groove 61, and the rear section of the guide groove 61 is open, so that it is convenient for the user to take the water tank 11.

[0094] Furthermore, the water tank pushing structure in this embodiment also includes a positioning mechanism 7 for detecting the position of the water tank 11. The positioning mechanism 7 is arranged on the water tank seat 12 and located at the rear side of the water tank 11. It includes a micro switch 71, a trigger member 72 and a reset spring 73. The trigger member 72 is slidably arranged on the water tank seat 12 along the in-and-out direction of the water tank 11. One end of the reset spring 73 is mounted on the trigger member 72, and the other end is mounted on the water tank seat 12. When the water tank 11 is not placed or in an open state, the trigger end 722 of the trigger member 72 abuts against the micro switch 71, the micro switch 71 is closed, and the reset spring 73 is in a natural state; when the water tank 11 is retracted, the force is transmitted to the contact end 721 of the trigger member 72 to make the trigger member 72 slide. When the water tank 11 is retracted into place, the trigger end 722 of the trigger member 72 is disengaged from the micro switch 71, the micro switch 71 is opened, and the reset spring 73 is compressed to store energy. The positioning mechanism 7 in this embodiment can detect the placement position of the water tank 11, thereby avoiding the phenomenon of failure to pump water or water leakage caused by incorrect placement of the water tank 11.

[0095] Furthermore, in this embodiment, the trigger member 72 is a rod extending in the front-to-back direction, the micro switch 71 is arranged on the left side of the trigger member 72, the front end of the trigger member 72 is the contact end 721, and the rear end is bent toward the micro switch 71 and its end forms the trigger end 722, the micro switch 71 is located in front of the trigger end 722, and the contact of the micro switch 71 is opposite to the trigger end 722. Since the movement stroke of the trigger member 72 in the direction of retracting the water tank 11 is large, the trigger member 72 is bent to form the trigger end 722, so as to avoid the problem of failure to pump water or water leakage caused by the water outlet of the water tank 11 and the water outlet joint of the water tank seat 12 not being properly combined during the placement of the water tank 11 due to the dimensional tolerance of the parts, and also avoid the problem of unevenness of the water tank panel 13 due to the dimensional tolerance of the parts. The buckle block 31 is extended from the front end of the slide bar 3 to one side to form an extension block 310, and the front end of the extension block 310 extends forward to form the buckle block 31, and the rear side of the extension block 310 forms a contact surface 3100 that can abut against the front end of the trigger member 72. In this way, the trigger member 72 is triggered by the interaction between the contact surface 3100 on the slide bar 3 and the trigger member 72, thereby opening and closing the micro switch 71. In this embodiment, the bottom surface of the lower cover 122 of the water tank seat 12 is raised upward to form a mounting groove 1221, the positioning mechanism 7 is arranged in the mounting groove 1221, and a through hole is provided on the front groove wall of the mounting groove 1221 for exposing the contact surface 3100, the front end of the trigger member 72 passes through the through hole and can be against the contact surface 3100 of the buckle block 31, the micro switch 71 is installed on the top surface of the mounting groove 1221, and at least one pair of sliding buckles 12211 is provided on the top surface of the mounting groove 1221. and the first mounting column 12212, the left and right side edges of the trigger member 72 are respectively inserted into the corresponding sliding buckles 12211 and can slide back and forth along the sliding buckles 12211, the trigger member 72 is hollowed out with a mounting window 7210, a second mounting column 7211 is provided on the front side of the mounting window 7210, the first mounting column 12212 is located in the mounting window 7210, and one end of the reset spring 73 is sleeved on the first mounting column 12212, and the other end is sleeved on the second mounting column 7211.

[0096] During the process of retracting the water tank 11, when the water tank 11 is put into place, the above-mentioned reset spring 73 is compressed, driving the trigger member 72 to move toward the rear side of the water tank seat 12, so that the trigger end 722 of the trigger member 72 is disengaged from the contact of the micro switch 71, the micro switch 71 is disconnected, and the water tank 11 is pushed into place. If the water tank 11 is not pushed into place, the trigger end 722 of the trigger member 72 and the contact of the micro switch 71 remain in a state of abutment, the micro switch 71 is turned on, and the position state of the water tank 11 can be judged by the on and off state of the micro switch 71. In addition, when the water tank 11 is pushed into place, the slide bar 3 is locked by the guide locking mechanism 6, so the contact end 721 of the trigger member 72 does not directly contact the water tank 11 but contacts the contact surface 3100 of the slide bar 3, which can avoid the reset spring 73 applying force to the water tank 11, causing the water outlet of the water tank 11 and the water outlet joint to not be properly combined, resulting in the problem of water not being pumped out or water leakage.

[0097] Embodiment 2:

[0098] like Figures 23 to 28 As shown, unlike Example 1, the water tank pushing out and retracting structure in this embodiment is not provided with the above-mentioned rebound component 5, guide locking mechanism 6 and positioning mechanism 7, and this embodiment can realize the automatic pushing out and retracting of the water tank 11. Specifically, this embodiment also includes a driving motor 81 and a transmission gear 82 arranged in the water tank seat 12, and the transmission gear 82 is installed on the output shaft of the driving motor 81 and meshes with the tooth surface 32 of the above-mentioned slide bar 3. In this way, in this embodiment, the driving motor 81 drives the transmission gear 82 to rotate and transmit it to the slide bar 3, thereby driving the slide bar 3 to slide back and forth along the slide groove 120, realizing the fully automatic pushing out and retracting of the water tank 11, enhancing the sense of technology, and greatly improving the user experience.

[0099] In this embodiment, the left and right groove surfaces of the above-mentioned buckle groove 4 continuously include a second guide inclined surface 414, a second limiting inclined surface 415 and a buckle surface 416 along the direction of the buckle block 31 being snapped in, wherein each second guide inclined surface 414 is inclined outward from front to back, each second guide inclined surface 414 is inclined inward from front to back, and the buckle surface 416 is a plane, and when each elastic pressure bead 311 is snapped into the corresponding buckle groove 4, each elastic pressure bead 311 is offset against the corresponding buckle surface 416. In this embodiment, the volume of the buckle block 31 matches the volume of the above-mentioned buckle groove 4. The design of the second guide inclined surface 414 can make the buckle block 31 better snap into or out of the buckle groove 4, and improve the feel of the water tank 11 being snapped in and out, and the design of the second limiting inclined surface 415 and the buckle surface 416 can make the buckle block 31 snap into the buckle groove 4 more firmly, thereby ensuring the stability of the water tank installation structure.

[0100] It further includes a push-out position switch 91 and a retracted position switch 92 installed in the water tank seat 12. The end of the slide bar 3 is provided with a trigger bar 33 that can abut against the contact of the push-out position switch 91, and the push-out position switch 91 is located at the front side of the trigger bar. When the slide bar 3 slides along the slide groove 120, the trigger bar 33 on the slide bar 3 can abut against or disengage from the contact of the push-out position switch 91. Moreover, when the trigger bar abuts against the contact of the push-out position switch 91, the push-out position switch 91 is turned on; when the trigger bar 33 disengages from the contact of the push-out position switch 91, the push-out position switch 91 is turned off. The setting of the push-out position switch 91 can effectively prevent the problem of the water tank 11 falling due to excessive pushing of the water tank 11.

[0101] Furthermore, it also includes a retraction position switch 92 installed in the water tank seat 12, and the retraction position switch 92 is located at the front side of the above-mentioned push-out position switch 91. The front end of the above-mentioned slide bar 3 extends vertically upward to form an extension block 310, and the front upper end of the extension block 310 extends forward to form the above-mentioned buckle block 31. The rear side surface of the extension block 310 forms a trigger surface 3101 that can touch the contact of the above-mentioned retraction position switch 92. During the sliding process of the slide bar 3 along the slide groove 120, the trigger surface 3101 can be against or disengaged from the contact of the push-out position switch 91, and when the trigger surface 3101 is against the contact of the retraction position switch 92, the retraction position switch 92 is turned on, and when the trigger surface 3101 is disengaged from the contact of the retraction position switch 92, the retraction position switch 92 is turned off, and when the retraction position switch 92 is turned on, the water tank 11 is retracted into place. The retracted position switch 92 can ensure that the water tank 11 is retracted into place, thereby avoiding the problem of failure to pump water or water leakage caused by the water tank 11 not being retracted into place.

[0102] In this embodiment, when the water tank 11 is retracted, it drives the slide bar 3 to move backward along the slide groove 120. When the trigger bar on the slide bar 3 is disengaged from the contact of the push-out position switch 91 and the push-out position switch 91 is disconnected, the system determines that the water tank 11 is in a retracted state, and the drive motor 81 starts to rotate clockwise to drive the slide bar 3 to move backward along the slide groove 120. When the water tank 11 touches the retracted position switch 92, the retracted position switch 92 is turned on, the water tank 11 is retracted into place, and the drive motor 81 stops working.

[0103] Embodiment 3:

[0104] like Figures 29 to 33 As shown, different from Example 2, this embodiment further includes a water tank position switch 93, which is located at the front side of the above-mentioned retracted position switch 92 and installed on the above-mentioned slide bar 3, and the length of the above-mentioned buckle groove 4 along the front-to-back direction is longer than the buckle block 31. When the front end surface of the buckle block 31 abuts against the front groove surface of the buckle groove 4, the rear side surface of the water tank 11 touches the contact of the water tank position switch 93.

[0105] When the buckle block 31 on the rack is inserted into the buckle slot 4 and the elastic pressure beads 311 on both sides of the buckle block 31 are respectively limited on the corresponding second limiting inclined surfaces 415, due to the inertia of the water tank 11 being pushed in, the buckle block 31 will continue to move toward the inside of the buckle slot 4 until the front end surface of the buckle block 31 abuts against the front groove surface of the buckle slot 4. Since the water tank position switch 93 is installed on the slide bar 3, the rear side of the water tank 11 touches the contact of the water tank position switch 93, and the water tank position switch 93 is turned on to trigger the reverse signal of the drive motor 81. Preferably, in this embodiment, an installation cavity 3102 is provided in the extension block 310, and the water tank position switch 93 is embedded in the installation cavity 3102 and its contact is exposed at the front end of the extension block 310, so that the water tank position switch 93 can be stably installed, and the contact of the water tank position switch 93 can better abut against the front groove surface of the buckle slot 4 to trigger the water tank position switch 93.

[0106] Thus, in this embodiment, by setting the push-out position switch 91, the retracting position switch 92 and the water tank position switch 93, the position of the water tank 11 can be more accurately judged, and misjudgment can be further avoided. Specifically: (1) When the push-out position switch 91 changes from open to closed, it means that the water tank 11 is pushed out to the limit position state. At the same time, the water tank position switch 93 changes from open to closed. At this time, if the water tank position switch 93 is open, it is judged that the water tank 11 is taken out; (2) When the water tank 11 is filled with water and put back, the above-mentioned water tank position switch 93 is closed and the drive motor 81 is reversed. As the slider 3 moves, the water tank position switch 93 and the push-out position switch 91 are simultaneously disconnected. When the water tank 11 touches the contact of the retracting position switch 92, the retracting position switch 92 is opened, and the water tank 11 is retracted into place. Thus, in this embodiment, when the water tank 11 is paused during the push-out or retracting process, the system can judge whether the water tank 11 is in the push-out process or the retracting process, and can continue according to the original process when continuing to execute.
