Description
Technical Field
[0001] The utility model relates to the field of clothing processing equipment, in particular to a switch control structure and an automatic delivery component. Background Art
[0002] An additive container is required in the clothing processing device to store additives for the convenience of processing clothing; the additive container is installed in the storage cavity of the clothing processing device. The clothing processing device is generally provided with a detection component to detect whether the additive container is installed correctly. The detection component includes a detection switch. When the additive container is installed in place, the additive container directly abuts the detection switch to confirm that it is installed in place. At that time, since the additive container directly abuts the detection switch, the force borne by the additive container will be directly transmitted to the detection switch, which can easily cause damage to the detection switch. Utility Model Content
[0003] In order to overcome the deficiencies in the prior art, the utility model provides a switch control structure and an automatic delivery assembly, which have the advantage that the switch body is not easily damaged by external forces.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A switch control structure includes a protective shell, a pressing piece and a switch body; the protective shell has a tube body with two ends open; the pressing piece is slidably arranged in the tube body; the switch body is located on one side of the tube body; the pressing piece is driven by an external force to trigger the switch body; the pressing piece includes a push rod, an elastic piece and a pressure rod; the push rod is away from the switch body and one end extends out of the tube body; the pressure rod is close to the switch body; the push rod and the pressure rod are telescopically connected to each other; the elastic piece is located between the push rod and the pressure rod and provides a thrust for the push rod and the pressure rod to move away from each other.
[0006] By adopting the above technical solution, an elastically retractable pressing piece is provided on the front side of the switch body, which can prevent the container bottle from directly pressing on the switch body, thereby reducing the possibility of the switch body being damaged by external forces. At the same time, after the container bottle is installed in place, when the clothes processing device vibrates, the elastically retractable pressing piece can play a buffering role, and the switch body is not easily damaged by external forces. In addition, the top rod and the pressure rod of the pressing piece are telescopically connected to form an integral whole. In this way, when the container bottle is not installed, the pressing piece can be completely separated from the switch body, reducing the possibility of accidental triggering of the switch body. At the same time, the pressing piece is assembled as a whole, thereby improving the assembly efficiency.
[0007] Optionally, the push rod has a telescopic sleeve; one end of the pressure rod is slidably set in the telescopic sleeve, and the other end extends out of the telescopic sleeve; a first limiting structure is provided on the telescopic sleeve; a second limiting structure is provided on the pressure rod; the first limiting structure and the second limiting structure cooperate with each other to limit the sliding distance of the pressure rod in the telescopic sleeve.
[0008] By adopting the above technical solution, the first limiting structure and the second limiting structure cooperate with each other to prevent the push rod and the pressure rod from being separated, thereby preventing the pressure rod from accidentally triggering the switch body.
[0009] Optionally, the first limiting structure is a telescopic guide groove formed on the side wall of the telescopic sleeve; the telescopic guide groove is parallel to the axial direction of the telescopic sleeve; and the second limiting structure is a telescopic guide block that cooperates with the telescopic guide groove.
[0010] By adopting the above technical solution, the telescopic guide block and the telescopic guide groove cooperate, which can not only prevent the push rod and the pressure rod from being accidentally separated, but also make the relative movement direction of the push rod and the pressure rod accurate, and avoid the elastic member from being subjected to torsion.
[0011] Optionally, it further includes a diaphragm; the edge of the diaphragm is pressed by the end of the tube body and the shell of the switch body to achieve sealing; the pressing member is driven by external force to change the shape of the diaphragm to trigger the switch body.
[0012] By adopting the above technical solution, the diaphragm is installed by pressing its edge against the end of the tube body and the shell of the switch body. Compared with the diaphragm being installed by adhesion, the diaphragm is more convenient to assemble and disassemble, and is convenient for assembly and subsequent replacement. In addition, the original shape of the diaphragm will not trigger the switch body. The switch body will only be triggered when the diaphragm is deformed. In this way, the diaphragm not only plays a sealing role, but also has a certain buffering effect.
[0013] Optionally, the diaphragm includes a dome and a sealing portion located circumferentially of the dome; the dome protrudes toward the pressing member; and the sealing portion is pressed by the end of the tube body and the shell of the switch body.
[0014] By adopting the above technical solution, the protruding direction of the dome of the diaphragm is toward the pressing piece, so that when the diaphragm is not subjected to force, the diaphragm will not contact the switch body, thereby avoiding accidental triggering of the switch body; at the same time, a sealing portion is provided on the circumference of the dome, and the sealing portion is pressed by the end of the tube body and the shell of the switch body, so that the connection area between the sealing portion and the tube body is increased, thereby improving the sealing performance.
[0015] Optionally, a concave stop is formed at one end of the tube body close to the switch body; and the sealing portion has a convex stop matched with the concave stop.
[0016] By adopting the above technical solution, the concave stopper of the tube body and the convex stopper of the sealing portion cooperate with each other, the installation position of the diaphragm and the tube body is more accurate, and the sealing performance of the two is improved.
[0017] Optionally, the convex stop and the concave stop are interference fit.
[0018] By adopting the above technical solution, the concave stopper of the tube body and the convex stopper of the sealing portion are interference fit, so that the diaphragm is not easily separated from the tube body, and the sealing performance of the two is improved.
[0019] Optionally, a folded portion is formed at the edge of the sealing portion; the end of the tube body is inserted into the folded portion; and the end of the tube body is interference fit with the folded portion.
[0020] By adopting the above technical solution, the folded portion with interference fit at the end of the tube body makes the connection between the diaphragm and the tube body more stable, while increasing the connection area between the diaphragm and the tube body and improving the sealing performance.
[0021] Optionally, when the push rod and the pressure rod are farthest apart, the deformation recovery force of the diaphragm is greater than the thrust provided by the elastic member.
[0022] By adopting the above technical solution, the distance between the push rod and the pressure rod is the smallest, indicating that the pressing part is not subjected to external force. The container bottle is removed. At this time, the deformation recovery force of the diaphragm is greater than the thrust provided by the elastic part, which can restore the diaphragm and prevent the diaphragm from pressing the switch body. The switch body is not triggered, avoiding misdetection of the switch body.
[0023] An automatic dispensing assembly comprises a shell and a container bottle; the shell is provided with a receiving cavity for inserting the container bottle; a press lock and the above-mentioned switch control structure are provided in the receiving cavity; the container bottle is locked in the receiving cavity by the press lock.
[0024] By adopting the above technical solution, the container bottle is locked by a push lock, so that disassembly and assembly can be achieved by simply pressing the container bottle, which is easy to operate. At the same time, the switch control structure detects whether the container bottle is installed in place, which is conducive to subsequent operations.
[0025] Optionally, the pressing direction of the container bottle is parallel to the moving direction of the push rod; the maximum pressing stroke of the container bottle is X; the locking stroke of the container bottle is Y; the maximum stroke of the push rod is Z; Y<X≤Z.
[0026] By adopting the above technical solution, when the container bottle is at the maximum pressing stroke, the push rod is closest to the switch body. At that time, since the maximum stroke of the push rod is greater than or equal to the maximum pressing stroke of the container bottle, the end of the push rod contacts the diaphragm or the switch body but does not apply force or there is a gap between the end of the push rod and the diaphragm or the switch body. The force applied to the switch body will only cause deformation of both the diaphragm and the elastic member or the deformation of the elastic member, thereby preventing the switch body from being damaged by external force.

[0037] The following is combined with Figures 1-5 The utility model is described in further detail.
[0038] Example 1: An automatic delivery component, refer to Figure 1 and Figure 2, including a shell 10, a container bottle 20, a push lock 30 and a switch control structure 40; the shell 10 is provided with a accommodating cavity 100; the container bottle 20 is inserted into the accommodating cavity 100; the push lock 30 and the switch control structure 40 are arranged at the inner end of the accommodating cavity 100; a connecting hook is provided on the container bottle 20, which is connected to the push lock 30 and locked in the accommodating cavity 100; the push lock 30 can be a plastic push lock buckle or an elephant trunk lock. The plastic push lock buckle and the elephant trunk lock are existing technologies and are not described here in detail. The container bottle 20 is locked and unlocked by pressing, so that the maximum pressing stroke X of the container bottle 20 is greater than the locking stroke Y of the container bottle 20, that is, after the container bottle 20 is pressed inward to the bottom, it will be locked by the push lock 30 after moving outward for a gap.
[0039] refer to Figure 3 The switch control structure 40 includes a protective shell, a pressing piece 46, a diaphragm 47 and a switch body 48; the protective shell includes a detection shell 41, a switch support plate 43 and a cover 44; the detection shell 41 and the cover 44 form a protective shell and the switch support plate 43, the pressing piece 46 and the diaphragm 47 are located in this protective shell; a tube body 42 with two ends opened is formed on the detection shell 41; the axial direction of the tube body 42 is parallel to the pressing direction of the container bottle 20; the container bottle 20 and the switch body 48 are located on both sides of the detection shell 41 and the cover 44 is tightened between the end of the tube body 42 and the switch body 48; the switch body 48 is fixed on the switch support plate 43; the switch support plate 43 is connected to the detection shell 41 by screws; the pressing piece 46 is slidably set in the tube body 42. During operation, the container bottle 20 is inserted into the accommodating cavity 100 from the outside to the inside. During this process, the pressing member 46 is driven to move to abut against the deformation of the diaphragm 47, thereby triggering the switch body 48. In addition, the diaphragm 47 can play a sealing role due to its own waterproofness, preventing the switch body 48 from malfunctioning due to moisture.
[0040] refer to Figure 3 and Figure 4 The pressing member 46 includes a push rod 461, an elastic member 462, and a pressure rod 463. The push rod 461, pressure rod 463, and tube body 42 are axially aligned. The push rod 461 is spaced away from the switch body 48 and one end extends out of the tube body 42. The pressure rod 463 is positioned close to the switch body 48. The push rod 461 and pressure rod 463 are telescopically connected as one. The elastic member 462 is located between the push rod 461 and pressure rod 463 and provides a force that pushes the push rod 461 and pressure rod 463 away from each other. To prevent the push rod 461 from directly abutting the diaphragm 47, the maximum stroke Z of the push rod 461 is greater than or equal to the maximum pressing stroke X of the container bottle 20. When the end of the push rod 461 contacts the diaphragm 47 but does not exert force, or when there is a gap between the end of the push rod 461 and the diaphragm 47, the force applied to the switch body 48 is only the sum of the deformation forces of the diaphragm 47 and the elastic member 462, thus preventing the switch body 48 from being damaged by external forces.
[0041] refer to Figure 3 and Figure 4 , the top rod 461 has a telescopic sleeve 4611; one end of the pressure rod 463 is slidably set in the telescopic sleeve 4611, and the other end extends out of the telescopic sleeve 4611; a pair of telescopic guide grooves 4610 are formed on the side wall of the telescopic sleeve 4611; the telescopic guide grooves 4610 are parallel to the axial direction of the telescopic sleeve 4611; a pair of telescopic guide blocks 4631 that cooperate with the telescopic guide grooves 4610 are formed on the pressure rod 463; the elastic member 462 is a compression spring; the compression spring is located in the telescopic sleeve 4611 and one end abuts against the top rod 461 and the other end abuts against the pressure rod 463; due to the presence of the elastic member 462 and the diaphragm 47, the switch body 48 receives the force absorbed by the elastic member 462 and the diaphragm 47, which plays a role in reducing vibrating effect; even if the force of the container bottle 20 is very large, the maximum force acting on the switch body 48 is only the spring force brought by the compression spring under the maximum displacement of the container bottle 20, thereby preventing the switch body 48 from being damaged by external force; in addition, due to the guiding effect of the telescopic guide block 4631 and the telescopic guide groove 4610, the relative movement positions of the push rod 461 and the pressure rod 463 are accurate. At the same time, since the telescopic guide block 4631 and the telescopic guide groove 4610 are connected, the pressing piece 46 is connected into a whole. In this way, when the container bottle 20 is not installed, the pressing piece 46 can be completely separated from the switch body 48, reducing the possibility of accidental triggering of the switch body 48. At the same time, the pressing piece 46 is assembled as a whole, thereby improving the efficiency of assembly.
[0042] In other embodiments, the telescopic sleeve 4611 can be provided on the pressure rod 463, while the telescopic guide block 4631 can be provided on the push rod 461. In the above two embodiments, the telescopic guide groove 4610 is located in the first limiting structure, while the telescopic guide block 4631 is the second limiting structure. The first limiting structure and the second limiting structure cooperate to limit the sliding distance of the pressure rod 463 within the telescopic sleeve 4611. Alternatively, an axial guide rod parallel to the axis of the push rod 461 or the pressure rod 463 can be provided on one of the push rod 461 and the pressure rod 463, and a guide hole that cooperates with the axial guide rod can be provided on the other. To allow the push rod 461 and the pressure rod 463 to disengage, a stop block can be provided at the end of the axial guide rod. In this case, the guide hole constitutes the first limiting structure, while the axial guide rod with the stop block constitutes the second limiting structure.
[0043] refer to Figure 4 and Figure 5The diaphragm 47 includes a dome 471 and a sealing portion 472 located circumferentially of the dome 471 ; the dome 471 protrudes toward the pressing member 46 ; the sealing portion 472 is compressed by the end of the tube 42 and the housing of the switch body 48 ; and the triggering point of the switch body 48 is located within the dome 471 . In other embodiments, the diaphragm 47 may also be sheet-shaped, with the edges of the diaphragm 47 compressed by the end of the tube 42 and the housing of the switch body 48 . When the pressing member 46 applies force to the diaphragm 47 , the diaphragm 47 deforms toward the triggering point of the switch body 48 to trigger the switch body 48 . However, compared to the embodiment in which the middle portion of the diaphragm 47 protrudes into the dome 471 , the sheet-shaped diaphragm 47 is more susceptible to failure. The diaphragm 47 with the dome 471 has a greater deformation recovery force and a longer service life. When the container bottle 20 leaves the accommodating chamber, the pressing member 46 is not subjected to force, and the push rod and the pressure rod are the farthest apart. At this time, the elasticity of the elastic member 462 is the smallest, and the deformation recovery force of the diaphragm 47 is greater than the elasticity of the elastic member 462, thereby ensuring that the diaphragm 47 is separated from the trigger point of the switch body 48, so that misdetection will not occur; in addition, when the container bottle 20 is locked, the sum of the deformation forces of the elastic member 462 and the diaphragm 47 is greater than or equal to the deformation recovery force of the diaphragm 47 and the closing retention force of the switch body 48, and the switch body 48 remains in the triggered state.
[0044] Example 2: The difference between Example 2 and Example 1 is that: in order to increase the sealing performance between the diaphragm 47 and the tube body 42; Figure 3 The end of the tube body 42 near the switch body 48 is formed with a concave stopper 420; the sealing portion 472 has a convex stopper 474 that matches the concave stopper 420. The concave stopper 420 and the convex stopper 474 increase the contact area between the diaphragm 47 and the tube body 42, thereby improving the sealing between the diaphragm 47 and the tube body 42. At the same time, the cooperation between the concave stopper 420 and the convex stopper 474 ensures a more accurate and stable installation position of the diaphragm 47. Of course, the interference fit between the concave stopper 420 and the convex stopper 474 improves the sealing and connection.
[0045] Example 3: The difference between Example 3 and Example 1 is: Figure 4 and Figure 5 , sealing, a stack of folded parts 473 are formed at the edge of 472; the end of the tube body 42 is inserted into the folded part 473; the end of the tube body 42 is interference fit with the folded part 473; this increases the contact area between the diaphragm 47 and the tube body 42, thereby increasing the sealing of the diaphragm 47 and the tube body 42; at the same time, it makes the installation position of the diaphragm 47 more accurate and stable.
[0046] Example 4: The difference between Example 4 and Example 1 is that the diaphragm 47 may not be provided between the switch body 48 and the tube body 42, and of course it does not have waterproof properties. At the same time, the force applied to the switch body 48 is only the deformation force of the elastic member 462.
[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
