Description

Technical Field

[0001] The invention belongs to the technical field of water level detection of clothing care machines, and in particular relates to a water level detection device for a water tank of a clothing care machine and a clothing care machine. Background Art

[0002] The clothing care machine converts the liquid water in the water tank into steam through a built-in steam generator and discharges the steam into the care cavity, thereby achieving the purpose of wrinkle removal and sterilization of clothing. Since the clothing care machine is easy to move, the water tank is detachable. When the float in the water tank drops to the sensing plate area along with the liquid level in the water tank, the reed switch on the sensing plate is subjected to the magnetic force to generate a subsequent electrical signal transmitted to the control end of the clothing care machine. The control end of the care machine issues an alarm indicating that the liquid level in the water tank is low and liquid water needs to be replenished in time. The water level detection device of the water tank of the existing clothing care machine is usually composed of the above-mentioned float, float mounting cylinder and sensing plate. The float mounting cylinder is vertically arranged, and the upper part of the float mounting cylinder is designed to be open. In order to facilitate the entry of liquid water, both side walls of the float mounting cylinder are provided with notches extending to the bottom.

[0003] For example, the Chinese patent with announcement number CN215328855U discloses a water level detection device for a water tank of a clothing care machine, which includes a floating member, a magnetic member, a floating groove, a sensing control board and a plurality of magnetic switches; the magnetic member is fixedly connected to the floating member; the floating groove and the water tank form a communicating vessel structure, and the floating member is movably arranged in the floating groove; a plurality of magnetic switches are arranged outside the floating groove and are arranged at equal height intervals, and each of the magnetic switches is electrically connected to the sensing control board; the floating member moves up or down in the floating groove as the water level changes, and when it moves to a preset height, the magnetic member corresponds to the magnetic induction of one of the magnetic switches.

[0004] However, the above scheme has the following deficiencies: the above patent document does not improve the float mounting tube and the float in the conventional water level detection device, the float mounting tube and the water tank are usually injection-molded integral parts, so the float mounting tube is mostly a plastic part, and the float mounting tube is prone to deformation during long-term use, causing the float to be stuck and unable to move, resulting in abnormal water level detection sensing. However, the existing float mounting tube does not effectively solve the above problem and can only be repaired and replaced, which is not economical.

[0005] To this end, we propose a water level detection device for a water tank of a clothing care machine and a clothing care machine to solve the problems mentioned in the above background technology. Summary of the invention

[0032] See also Figure 1-12 , the present invention provides a technical solution:

[0033] Embodiment 1:

[0034] A water level detection device for a water tank of a clothing care machine comprises a water tank body 1 and a mounting cylinder body 2 arranged at the bottom end thereof, both side walls of the mounting cylinder body 2 are provided with notches and extend to the bottom end surface of the water tank body 1, a sensing plate 3 is bonded to the lower part of the inner wall of the mounting cylinder body 2, a reed switch is arranged on the sensing plate 3, and the reed switch is a prior art product and will not be described in detail, the bottom end of the water tank body 1 is located at both sides of the mounting cylinder body 2 and is connected to a sinking tank box 4, liquid water in the water tank body 1 can be injected into the sinking tank box 4, and the sinking tank box 4 is vertically connected to the bottom wall of the mounting cylinder body 2. A pull-down spring sleeve rod 5 is welded to the bottom, and the pull-down spring sleeve rod 5 is composed of a pull-down spring and a pull-down rod. An auxiliary float 6 is slidably sleeved on the pull-down spring sleeve rod 5. The auxiliary float 6 can float with the change of the liquid level in the water tank body 1. A push inclined plate 7 is welded to the upper end of the auxiliary float 6. The push inclined plate 7 is inclined, and the angle between the plane where the center line of the push inclined plate 7 is located and the plane where the horizontal line is located is 70°. A push clamp 8 is screwed or bonded to the top of the push inclined plate 7, and the side of the push clamp 8 is a double-ear structure.

[0035] A bearing hole plate 9 is screwed and fixed to the upper part of the inner wall of the installation cylinder 2 in the horizontal direction. A rotating shaft 10 is inserted through the inner ring of the bearing hole on the bearing hole plate 9. The rotating shaft 10 can rotate freely on the bearing hole plate 9. The upper and lower parts of the rotating shaft 10 are respectively fixed with a gear body 11 and a thrust transverse plate 12. The thrust transverse plate 12 is a rectangular plate structure. Both sides of the thrust transverse plate 12 are bonded or screwed with thrust arc blocks 13. The thrust arc blocks 13 are superior arc block structures. The upper end surface of the thrust transverse plate 12 is symmetrically provided with vertical holes 102. The vertical holes 102 are of a square structure. The vertical holes 102 on both sides of the upper end of the thrust transverse plate 12 are fixed with a gear body 11 and a thrust transverse plate 12. The vertical rods 14 are all penetrated along the vertical sliding, and the square structure design of the vertical hole 102 prevents the vertical rods 14 from deflecting during the vertical sliding process. The upper outer wall of the vertical rods 14 is vertically bonded or screwed with a guide block 15, and the push clamping block 8 of the double-ear structure is convenient for limited sliding connection with the guide block 15. The bottom ends of the vertical rods 14 on both sides are clamped and fixed with float balls 16, and the float balls 16 can float up and down with the change of the water level in the water tank body 1. The adjacent float balls 16 are flush and fixedly connected. The cooperation of the push clamping block 8 and the guide block 15 indirectly limits the rotation of the pushed horizontal plate 12;

[0036] The front and rear diagonal positions of the pushed transverse plate 12 are all screwed and fixed with notch fixing blocks 17, which are U-shaped structures. The bottom end of the inner wall of the notch fixing block 17 is provided with an anti-collision notch, and a groove 103 is provided on the upper part of the inner wall of the mounting cylinder 2. A reset spring sleeve rod 18 is detachably fixed in the groove 103 on the upper part of the inner wall of the mounting cylinder 2 along the transverse direction. A transverse rack 19 is slidably connected to the reset spring sleeve rod 18, and the gear body 11 and the transverse rack 19 can be fully meshed and connected. The initial state of the reset spring on the reset spring sleeve rod 18 is a stretched state. The reset spring on the reset spring sleeve rod 18 can drive the transverse rack 19 to move in the right direction, thereby driving the gear body 11 to rotate. A preset hole is provided on the transverse rack 19, and a locking spring is movably penetrated in the preset hole on the front end face of the transverse rack 19 The sleeve rod 20, the locking spring sleeve rod 20 has a spring force in the direction of the groove 103, the extended end of the locking spring sleeve rod 20 is engaged with the reset spring sleeve rod 18, at this time the reset spring on the reset spring sleeve rod 18 is in a stretched state, the locking spring sleeve rod 20 can temporarily fix the transverse rack 19 to avoid being pushed by the reset spring, the adjacent side push inclined plate 7 is bonded or screwed with an unlocking magnetic inclined block 21, the unlocking magnetic inclined block 21 is a permanent magnet, the unlocking magnetic inclined block 21 is an inclined L-shaped structure, the angle between the plane where the center line of the unlocking magnetic inclined block 21 is located and the plane where the horizontal line is located is 60°, which is convenient for the unlocking magnetic inclined block 21 to slide and push with the end of the pushed arc block 13 after rotation, and the rotation trajectory of the unlocking magnetic inclined block 21 can pass through the anti-collision notch on the notch fixing block 17 after rotation;

[0037] A proximity locking assembly is provided between the lower part of the notched end on both sides of the installation cylinder 2 and the auxiliary float 6 and the float ball 16. The proximity locking assembly can lock the auxiliary float 6 when the auxiliary float 6 and the float ball 16 move down to the bottom to prevent the auxiliary float 6 from entering the sinking tank box 4. When the auxiliary float 6 enters the sinking tank box 4, the proximity locking assembly is in an unlocked state. At this time, the float ball 16 is in a stuck state. After the auxiliary float 6 drops in the liquid level, it will drive the push clamp 8 to separate from the guide rail block 15. When the auxiliary float 6 completely enters the sinking tank box 4, the push clamp 8 is inserted and fixed on the notched fixing block 17 to fix the rotated pushed cross plate 12. In the process of the downward movement of the push inclined plate 7, the unlocking magnetic inclined block 21 will be driven to move downward, and the downward movement trajectory of the unlocking magnetic inclined block 21 is opposite to the end face of the locking spring sleeve rod 20. The unlocking magnetic inclined block 21 can lock the locking spring The sleeve rod 20 generates an outward magnetic attraction, which drives the locking spring sleeve rod 20 to separate from the return spring sleeve rod 18. At this time, the transverse rack 19 loses its fixed restraint, and the return spring sleeve rod 18 drives the pushed transverse plate 12 to rotate through the cooperation of the transverse rack 19 and the gear body 11. Specifically, the return spring sleeve rod 18 can drive the transverse rack 19 to move horizontally to the right, and the engagement of the transverse rack 19 with the gear body 11 can drive the pushed transverse plate 12 at the lower part of the rotating shaft 10 to rotate. Since the push clamping block 8 and the guide rail block 15 are designed to be separated, the pushed transverse plate 12 rotates horizontally, which can drive the float balls 16 at the bottom of the vertical rods 14 on both sides to rotate, so that the two float balls 16 are adjusted from a horizontal side-by-side arrangement to an oblique arrangement, which can reduce the horizontal space of the installation cylinder 2 occupied by the two float balls 16, and facilitate the removal of the stuck float ball 16.

[0038] Embodiment 2:

[0039] On the basis of the first embodiment, the auxiliary float 6 is further explained. The two sides of the auxiliary float 6 are respectively bonded or clamped with a counterweight slider 22 and a buoyancy box 23. The counterweight slider 22 can increase the overall weight of the buoyancy box 23, and the design of the buoyancy box 23 ensures that the auxiliary float 6 can float up and down following the changes in the liquid level in the water tank body 1. The upper end surface of the counterweight slider 22 is symmetrically provided with vertical holes 24, and two pull-down spring sleeve rods 5 slide through the corresponding vertical holes 24. The pull-down spring sleeve rod 5 can limit the vertical movement direction of the auxiliary float 6, and the pull-down spring sleeve rod 5 can generate a downward pulling force on the auxiliary float 6. When the float ball 16 is stuck, the auxiliary float 6 can be pulled down to the bottom of the sinking tank box 4 by the pull-down spring sleeve rod 5, and the pull-down spring sleeve rod 5 will not affect the floating of the float ball 16 following the changes in the liquid level. The bottom end of the auxiliary float 6 is glued or screwed with a receiving magnet block 201, and the outer surface of the receiving magnet block 201 is coated with anti-rust paint. The anti-rust paint is a prior art product and will not be described in detail. A magnetic block 202 is provided at the bottom end of the inner wall of the sinking trough box 4. The magnetic block 202 is a magnet. The receiving magnet block 201 can be magnetically connected to the magnetic block 202, thereby auxiliary fixation of the auxiliary float 6 after sinking. At the same time, when the auxiliary float 6 enters the sinking trough box 4, it can generate a downward magnetic attraction force on the auxiliary float 6, which is convenient for the rapid sinking of the auxiliary float 6. A locking groove 101 is provided on the side wall of the counterweight slider 22. The auxiliary float 6 is matched with the buoyancy box 23 to float up and down simultaneously with the float ball 16, and the push clamp 8 slides vertically on the guide rail block 15, thereby preventing the pushed cross plate 12 from rotating.

[0040] Embodiment three:

[0041] On the basis of the first embodiment, the proximity locking assembly is further described. The proximity locking assembly includes a main magnetic block 25 and a secondary magnetic block 26 respectively arranged at the lower part of the notch end of the mounting cylinder 2 and the outer part of the float ball 16. The side of the main magnetic block 25 is screwed or bonded with a locking cone block 27. The upper part of the locking cone block 27 extending into the notch is designed to be oblique. The notch of the mounting cylinder 2 is bonded or screwed with an outward push spring fixed hole block 28. The outward push spring fixed hole block 28 is composed of a fixed hole block and an outward push spring symmetrically arranged thereon. The locking cone Block 27 passes through the fixed hole block, and the main magnetic block 25 and the auxiliary magnetic block 26 repel each other with the same poles when they are close to each other. The outward push spring can generate a spring thrust on the main magnetic block 25 in the direction of the induction plate 3. The outward push spring and the auxiliary magnetic block 26 act on the main magnetic block 25 in opposite directions. When the float ball 16 moves down to the induction plate 3 area, the auxiliary magnetic block 26 overcomes the reverse force of the outward push spring and pushes the locking cone block 27 into the locking groove 101, thereby fixing the auxiliary float ball 6 that moves down to prevent the auxiliary float ball 6 from entering the sinking tank box 4.

[0042] Embodiment 4:

[0043] On the basis of the first embodiment, the push clamp block 8 and the reset spring sleeve rod 18 are further described. The bottom of the push clamp block 8 is an arc edge structure. The arc edge structure is designed to facilitate the push clamp block 8 to slide along the edge of the pushed arc block 13 when it moves downward, and only when the push clamp block 8 is separated from the guide rail block 15, the push inclined plate 7 will contact the pushed arc block 13. At the same time, the rotation of the gear body 11 will drive the rotation of the pushed cross plate 12. When the push clamp block 8 is separated from the guide rail block 15, the push inclined plate 7 moves downward to push the pushed arc block 13 to rotate around the rotating shaft 10, thereby adjusting the floats on both sides below. The ball 16 is rotated and offset, and a through hole is preset on the inner wall of the notch fixing block 17. A fixed spring sleeve rod 29 is movably penetrated in the through hole on the notch fixing block 17. The fixed spring sleeve rod 29 has a spring thrust extending inward. The upper end of the extending portion of the fixed spring sleeve rod 29 is an oblique cone structure, and a fixing hole 30 is provided on the inner wall of the push clamp 8. This design facilitates the push clamp 8 to slide down into the notch fixing block 17 to push the fixed spring sleeve rod 29 to retract. When the fixed spring sleeve rod 29 is opposite to the fixing hole 30 on the push clamp 8, after the pushed arc block 13 is flipped, the fixed spring sleeve rod 29 is pushed back. The extended end of the fixed spring sleeve rod 29 passes through the fixing hole 30, thereby fixing the rotated thrust transverse plate 12. At this time, it means that the transverse rack 19 is fully engaged with the gear body 11, and the thrust transverse plate 12 has made the maximum rotation. The rear end surface of the transverse rack 19 is bonded or screwed with a sliding hole block 31, and a sliding hole is preset on the sliding hole block 31. The sliding hole block 31 is slidably sleeved on the reset spring sleeve rod 18 through the sliding hole. The spring on the reset spring sleeve rod 18 can generate a reset spring pulling force to the right side on the sliding hole block 31. The front end of the upper rod body of the reset spring sleeve rod 18 is provided with a slot 32 The extended end of the locking spring sleeve rod 20 is inserted into the slot 32. The setting of the locking spring sleeve rod 20 can temporarily prevent the transverse rack 19 from moving. The top of the guide block 15 is screwed or bonded with a block 33. The block 33 can prevent the push clamp 8 from detaching from the upper end of the guide block 15, and when the push clamp 8 is stuck, the auxiliary float 6 can float freely. The floating of the auxiliary float 6 will indirectly drive the push clamp 8 to push the block 33 upward, so that the vertical rod 14 can generate an upward thrust on the float ball 16 stuck below, effectively reducing the probability of the float ball 16 getting stuck.

[0044] The working principle is as follows: when using the installation cylinder 2 in the water tank body 1, first install the push-out spring fixing hole blocks 28 at the lower part of the notch ends on both sides of the installation cylinder 2, and make the locking cone block 27 on the main magnetic block 25 pass through the push-out spring fixing hole blocks 28, so that the push-out spring on the push-out spring fixing hole blocks 28 is connected to the inner side of the main magnetic block 25, and then adjust the vertical rod 14 and the push inclined plate 7, so that the float ball 16 can float up and down with the auxiliary float ball 6 at the same time following the change of the liquid level inside the water tank body 1. It is necessary to ensure that the float ball 16 moves down to the lowest position of the installation cylinder 2, that is, the float ball 16 enters When entering the induction plate 3 area, the locking groove 101 on the counterweight slider 22 on the side wall of the auxiliary float 6 can be arranged opposite to the locking cone block 27, and the opposite surfaces between the auxiliary magnetic block 26 and the main magnetic block 25 on the outside of the float ball 16 are at the same level and repel each other, so that the main magnetic block 25 overcomes the outward spring force on the outward spring fixing hole block 28 to insert the locking cone block 27 into the locking groove 101, temporarily fixing the auxiliary float 6 to prevent the auxiliary float 6 from entering the sinking tank box 4, and in the above process, the push inclined plate 7 will not contact the pushed arc block 13, and the unlocking magnetic inclined block 21 is always located above the locking spring sleeve rod 20;

[0045] If the inner wall of the installation cylinder 2 is deformed so that any one of the float balls 16 on both sides is stuck with the inner wall of the installation cylinder 2 and cannot float up and down, the float ball 16 will not float up and down with the change of the liquid level in the water tank body 1. However, the auxiliary float ball 6 can float up and down with the change of the liquid level. First, when the liquid level in the water tank body 1 rises, the auxiliary float ball 6 will float up, and the auxiliary float ball 6 will indirectly drive the push clamp 8 to generate an upward thrust on the stopper 33, thereby trying to disengage the stuck float ball 16 from the stuck state. If the float ball 16 cannot be disengaged, the auxiliary float ball 6 will move down after the liquid level drops. When the push clamp 8 is separated from the guide block 15, the pushed cross plate 12 loses its rotation restraint, and the unlocking magnetic inclined plate 7 is released. The downward movement trajectory of the block 21 can be opposite to the locking spring sleeve rod 20. After the unlocking magnetic inclined block 21 approaches the locking spring sleeve rod 20, it can be moved out of the card slot 32. After the transverse rack 19 loses the restraint of the locking spring sleeve rod 20, it slides to the right side under the spring restoring force of the reset spring sleeve rod 18 on the sliding hole block 31. The transverse sliding of the transverse rack 19 can drive the pushed transverse plate 12 to rotate within a range through the gear body 11 and the rotating shaft 10, so that the two horizontally arranged float balls 16 can be adjusted to a mutually inclined state. The adjusted two float balls 16 have overlapping parts in the main view of the installation cylinder 2. The two float balls 16 are separated from each other in the normal state; during the rotation of the pushed transverse plate 12, the auxiliary float ball 6 follows the liquid The position drops and moves downward, so that the pushing inclined plate 7 and the pushing clamping block 8 can make a final fine adjustment to the pushed arc block 13. The unlocking magnetic inclined block 21 on the pushing inclined plate 7 can pass through the anti-collision notch on the notch fixing block 17, and the pushing clamping block 8 will be inserted into the notch fixing block 17 to push the oblique edge of the fixed spring sleeve rod 29, so that the fixed spring sleeve rod 29 is inserted into the fixing hole 30 on the pushing clamping block 8 for fixing, preventing the pushed cross plate 12 from rotating. In the above process, when the liquid level of the water tank body 1 is above the sinking tank box 4, the buoyancy generated by the liquid level in the water tank body 1 on the auxiliary float 6 can overcome the downward pulling force generated by the pull-down spring sleeve rod 5 to float up, and the liquid water in the sinking tank box 4 can also be operated by the clothing care machine When used, when the liquid level in the water tank body 1 is located in the sinking tank box 4, the float ball 16 is stuck and cannot be sensed by the sensor plate 3, resulting in the nursing machine being unable to issue a water shortage warning. Therefore, the liquid water in the sinking tank box 4 is gradually used and the liquid level drops, and then the auxiliary float ball 6 is successively subjected to the downward pulling force composed of the pull-down spring sleeve rod 5 and the magnetic suction block 202, so that the auxiliary float ball 6 enters the sinking tank box 4 and is fixed. At this time, the push clamp 8 can be fixed on the notch fixing block 17, so that when the mounting cylinder 2 is deformed and the float ball 16 is stuck, the float ball 16 is released from the stuck state by rotating the pushed cross plate 12, thereby ensuring the normal induction of water level detection, reducing the subsequent maintenance and replacement frequency, and being more economical.
