Description

Technical Field

[0001] This invention relates to a discharge port sealing structure and a material distributor. Background Technology

[0002] In all areas of social production and daily life, there are devices that require the dispensing of materials, such as various types of dishwashers, including detergent dispensers. Existing detergent dispensers include those for solid detergents such as dishwasher tablets and dishwasher powder. In some existing solutions, dishwasher tablet dispensers utilize the weight of the tablets themselves for dispensing. Under normal circumstances, the tablets can slide down by their own weight. However, this method of dispensing directly from the tablet storage cavity has significant sealing defects at the cavity outlet. This can easily cause the tablets inside the cavity to become damp and deteriorate, affecting the washing effect. Furthermore, when the tablets or the inner wall of the storage cavity become damp, they may stick to the cavity wall or interfere with dispensing, further hindering the dispensing process. Summary of the Invention

[0003] In view of this, the present invention provides a discharge port sealing structure and a material distributor, such as a dishwashing block distributor.

[0004] The discharge port sealing structure according to the present invention includes: a discharge port arranged in a plane perpendicular to the vertical direction to allow material to be discharged downward, and the discharge port including an outer sealing wall circumferentially surrounding the discharge port, the outer sealing wall extending downward relative to the plane of the discharge port and the inner side surface of the outer sealing wall being spaced apart from the outer peripheral edge of the discharge port; a sealing cap assembly configured to pivot about a pivot axis parallel to the plane of the discharge port to pivot between a closed position sealing the discharge port and an open position opening the discharge port, and the sealing cap assembly including: a sealing cap body including a circumferential sidewall, wherein, in the closed position, the circumferential sidewall is sealingly engaged with the inner side surface of the outer sealing wall.

[0005] Preferably, the sealing cap body includes a circumferential groove located inside the circumferential sidewall and recessed into the sealing cap body.

[0006] Preferably, in the closed position, the circumferential groove covers the discharge port.

[0007] Preferably, the outer peripheral edge of the discharge port includes a circumferential flange that projects outward relative to the plane of the discharge port, wherein, in the closed position, the circumferential flange is located above the circumferential groove.

[0008] Preferably, the inner side of the circumferential flange and the inner sidewall of the discharge port together form the discharge port guide wall.

[0009] Preferably, the discharge port includes a sloping inner wall, wherein, when viewed in the closed position, the sloping inner wall extends obliquely upward from one side of the outer peripheral edge of the discharge port.

[0010] Preferably, the sealing cover body includes a sealing ring and a groove on the circumferential sidewall, the sealing ring being disposed in the groove, and in the closed position, the sealing ring being sealed and engaged with the inner sidewall of the outer sealing wall.

[0011] Preferably, the inner facade has a shape that gradually expands outward along the vertical downward direction.

[0012] Preferably, the sealing cover body includes a slag collection trough, which is formed by the inner surface of the sealing cover body facing the discharge port and the circumferential sidewall, and in the closed position, the slag collection trough is open in the vertically upward direction.

[0013] Preferably, the sealing cap assembly can be driven by a driver to pivot between an open position and a closed position.

[0014] The material dispenser according to the present invention includes: a discharge port sealing structure as described above, a housing including a storage portion for storing materials and including the discharge port, the discharge port being disposed on the lower side of the storage portion.

[0015] Preferably, the storage section includes a driver comprising a push rod capable of reciprocating vertically to push material in the storage section downwards, and the push rod includes a drive portion; the sealing cap body includes a driven boss extending vertically from the inner surface of the sealing cap body, and the driven boss includes a guide groove formed on a surface of the driven boss perpendicular to the pivot axis; wherein the guide groove includes at least a first segment and a second segment, the first segment extending substantially parallel to the horizontal direction when viewed in the closed position, and the second segment extending from a first end of the first segment, wherein the first end of the first segment is further away from the pivot axis than the second end of the first segment; wherein the drive portion is disposed within the guide groove of the driven boss to allow the sealing cap assembly to be driven by the push rod reciprocating vertically to pivot between an open position and a closed position.

[0016] Preferably, when viewed in the closed position, both the first and second segments extend generally in a horizontal direction, or when viewed in the closed position, the second segment extends obliquely upward relative to the first segment.

[0017] Preferably, the housing further includes a dispensing section located below the storage section, and the storage section is connected to the dispensing section via a discharge port.

[0018] Preferably, the dispensing section includes a sliding channel that communicates with and extends downward from the discharge port, a channel outlet, and a movable cover that covers the channel outlet, the channel outlet being arranged in a vertical direction; wherein, the upper edge of the movable cover is pivotally connected to the upper edge of the sliding channel via a pivot, so as to be able to pivot between a vertical position with the channel outlet closed and an inclined position with the channel outlet open.

[0019] This invention proposes a sealing structure for the vertically oriented discharge port and a material distributor arranged in the vertical direction. This ensures that when the sealing cap assembly is open, the material does not contact the sealing interface of the sealing cap assembly during discharge, preventing contamination of the sealing interface and thus maintaining the sealing effect. The material distributor also preferably uses a push rod to control the dispensing of the dishwasher tablets, allowing the push rod to force the tablets out even when they are damp and adhere to the container wall or slightly interfere with it. Simultaneously, the push rod drives the sealing cap assembly, achieving linkage between the dispensing of the dishwasher tablets and the opening and closing of the sealing cap assembly. This further simplifies the dispensing and sealing mechanism and achieves a sealing and dispensing effect superior to existing technologies. Attached Figure Description

[0028] The invention will now be further described with reference to the accompanying drawings. For ease of description, the terms "inner," "inner side," or "inward" will be used in the following descriptions of the interior of the material dispenser (e.g., a dishwashing block dispenser), and the terms "outer," "outer side," or "outward" will be used in the following descriptions of the exterior of the material dispenser. "Up," "down," "vertical," and "horizontal" are relative to the arrangement of the material dispenser in the working state.

[0029] The outlet sealing structure according to the present invention can be applied to various devices, apparatuses, or equipment that require outlet sealing, and the material dispenser according to the present invention can be any suitable material dispenser applicable to various fields, especially for distributing solid material blocks. Hereinafter, the outlet sealing structure and material dispenser according to the present invention will be described using a typical dishwashing block dispenser as an example.

[0030] See Figure 1 A dishwasher tablet dispenser, acting as a material distributor, is installed on the dishwasher door. This dispenser is capable of vertically distributing dishwasher tablets into the dishwasher. Specifically, dishwasher tablets can be added to the dispenser when the door is open, and the dispenser can distribute dishwasher tablets into the dishwasher when the door is closed. In other words, the dishwasher tablet dispenser is arranged in a roughly vertical direction when in operation.

[0031] See Figure 2-8 A schematic diagram of a dishwasher tablet dispenser, as a material dispenser according to the present invention, is shown. The outlet sealing structure according to the present invention is applied to this dishwasher tablet dispenser. Specifically, as... Figure 2-4 As shown in Figure 6, the discharge port sealing structure mainly includes: discharge port 1 and sealing cover assembly 2.

[0032] The discharge port 1 is arranged in a plane P perpendicular to the vertical direction (relative to the working state of the dishwasher tablet dispenser, i.e., when the dishwasher door is closed) to allow the dishwasher tablets to be discharged downwards. The discharge port 1 includes an outer sealing wall 10 that surrounds the discharge port 1 circumferentially. The outer sealing wall 10 extends downwards relative to the plane P where the discharge port 1 is located, and the inner side 101 of the outer sealing wall 10 is spaced apart from the outer peripheral edge 11 of the discharge port 1. The discharge port 1 can be, for example, a square shape with rounded corners as shown in the figure; however, it should be understood that, depending on different design requirements, the discharge port can also be a rectangle with rounded corners or other polygonal shapes.

[0033] The sealing cap assembly 2 is configured to pivot about a pivot axis 20 parallel to the plane P where the outlet 1 is located, so as to pivot between a closed position sealing the outlet 1 and an open position opening the outlet 1. This pivot axis 20 may, for example, be located outside the outer sealing wall 10. The sealing cap assembly 2 includes a sealing cap body 21, which includes a circumferential sidewall 210. In the closed position, the circumferential sidewall 210 is sealingly engaged with the inner facade 101 of the outer sealing wall 10.

[0034] To further aid in sealing, the circumferential sidewall 210 of the sealing cover body 21 can be formed of a material or material coating (such as rubber, resin, etc.) that has a certain elasticity and is suitable for sealing. Thus, when the circumferential sidewall 210 is joined with the inner sidewall 101, the circumferential sidewall 210 can fit tightly with the inner sidewall 101 (even undergoing a certain elastic deformation, interference fit, etc.) to achieve a full seal.

[0035] According to the present invention, the dishwasher tablets are designed to be discharged downwards, which has significant advantages over the prior art design where dishwasher tablets are discharged from a horizontally arranged outlet. In the case of horizontal discharge, because the dishwasher tablets are sticky and produce residue, they easily scrape against the edge of the outlet as they fall downwards, contaminating the sealing structure and causing corrosion and deterioration of the sealing effect. In the present invention, in the closed position, the outer sealing wall 10 near the outlet 1 and the circumferential sidewall 210 of the sealing cap body 210 are arranged approximately vertically, providing a sealing structure outside the outlet and in the vertical direction. This sealing structure ensures that when the sealing cap assembly is open, the dishwasher tablets do not come into contact with the sealing interface between the sealing cap assembly and the outer sealing wall during discharge, preventing contamination of the sealing interface and damage to the sealing effect.

[0036] More preferably, see Figure 3 The sealing cap body 21 may include a circumferential groove 211, which may be located inside the circumferential sidewall 210 and recessed into the sealing cap body 21. Preferably, in the closed position, the circumferential groove 211 may cover the discharge port 1. The groove 211 can collect debris falling from the dishwashing block above the discharge port 1, so that in the closed position, the dishwashing block debris above the discharge port 1 will not slide onto the sealing interface and thus compromise the sealing effect.

[0037] More preferably, see Figure 3The outer peripheral edge 11 of the discharge port 1 may include a circumferential flange 110 projecting outward in a direction relative to the plane P on which the discharge port 1 is located. In the closed position, the circumferential flange 110 is positioned above the circumferential groove 211 to guide dishwashing tablet debris into the circumferential groove 211. Preferably, the end of the circumferential flange 110 may gradually narrow, so that the end of the circumferential flange 110 is positioned above the circumferential groove 211 but does not completely block the circumferential groove 211. Because the circumferential flange 110 is positioned directly opposite the circumferential groove 211, the sliding dishwashing tablet debris can be better guided directly into the circumferential groove, preventing it from sliding towards the sealing interface and further preventing contamination of the sealing surface.

[0038] More preferably, see Figure 3 The inner side of the circumferential flange 110 can form a discharge guide wall together with the inner sidewall 12 of the discharge port 1. This discharge guide wall has a certain length in the vertical direction to regulate the position of the dishwashing block and prevent it from tilting, thereby ensuring that the dishwashing block slides out smoothly in the correct posture when it is put in.

[0039] More preferably, see Figure 3 The discharge port 1 may also include a sloping inner wall 13. When viewed in the closed position, this sloping inner wall 13 extends upward at an angle from one outer peripheral edge of the discharge port 1 (e.g., the outer peripheral edge near the pivot axis 20). This sloping inner wall is more conducive to collecting dish soap crumbs. Due to the presence of the sealing interface, the discharge port is inevitably smaller than the thickness and width of the storage section of the material distributor (i.e., the dish soap dispenser) (described in detail later). This sloping guide structure at the connection between the discharge port and the storage section facilitates the sliding of dish soap crumbs into the aforementioned groove of the sealing cover body, ensuring that the internal space of the storage section is clean and hygienic, and preventing the accumulation of crumbs from affecting the transmission or dispensing action of the relevant moving mechanism.

[0040] More preferably, see Figure 3-4 The sealing cover body 21 may include a sealing ring 220 and a groove 212 on the circumferential sidewall 210. The sealing ring 220 may be disposed within the groove 212, and in the closed position, the sealing ring 220 is in sealing engagement with the inner sidewall 101 of the outer sealing wall 10. The sealing ring 220 may, for example, have a certain number of sealing lips. The sealing ring 220 may also be fixedly connected to the circumferential sidewall 210 by means of welding, bonding, injection molding, etc.

[0041] More preferably, see Figure 3 The inner facade 101 of the outer sealing wall 10 can have a form that gradually expands outward in the vertically downward direction. This expanded form of the inner facade 101 is more conducive to the entry and sealing engagement of the circumferential sidewall 210 of the sealing cover body 21.

[0042] More preferably, see Figure 4 The sealing cap body 21 may include a slag collection trough 213. This slag collection trough 23 is formed by the inner surface 214 of the sealing cap body 21 facing the discharge port 1 and a circumferential sidewall 210, and in the closed position, the slag collection trough 213 is open in a vertically upward direction. More preferably, the slag collection trough can substantially completely cover the discharge port when the sealing cap assembly is closed, so that dishwashing tablet debris can completely fall into the slag collection trough (and the aforementioned groove) without falling onto the sealing interface and compromising the sealing effect. Furthermore, each time the contents are dispensed, as the sealing cap assembly pivots downwards from the closed position to the open position, the debris in the slag collection trough falls out, thereby emptying the slag collection trough.

[0043] More preferably, the sealing cap assembly 2 can be driven by any suitable actuator to pivot between an open position and a closed position. See, for example, [example missing]. Figure 7 The pivoting of the sealing cap assembly can be achieved by providing shaft holes and rotating shafts on the housing of the material dispenser (i.e., the dishwasher tablet dispenser) and the sealing cap body. A suitable drive motor can then be installed at this pivoting structure to drive the rotation of the rotating shaft. Alternatively, a driving force can be applied to other parts of the sealing cap body to achieve the pivoting of the sealing cap assembly. A driving method that combines the drive of the dishwasher tablet push rod with the drive of the sealing cap assembly is described later.

[0044] The present invention also provides a material dispenser, particularly a dishwashing block dispenser, and the material dispenser of the present invention will be described below using a dishwashing block dispenser as an example. See details. Figure 2-8 As shown in the figure, the dishwasher tablet dispenser includes the previously described outlet sealing structure and housing 3. The housing 3 includes a storage section 30 for storing dishwasher tablets (i.e., the material) and includes the outlet 1, which is located on the lower side of the storage section 30. Figure 2 , 6 As shown in Figures 7 and 8.

[0045] More preferably, the storage section 30 includes a drive 31. The drive 31 may include a push rod 32 capable of reciprocating vertically to push the dishwasher tablets in the storage section 30 downwards. Specifically, the push rod may include a pushing part (not shown) for pushing the dishwasher tablets, so that even if the tablets are damp and adhere to the inner wall of the housing or slightly interfere with it, they can be forcibly pushed out by the pushing part of the push rod. Furthermore, existing horizontal pushing dispensing structures typically have high requirements for the size of the dishwasher tablets. When dispensing small-sized dishwasher tablets, insufficient pushing stroke may lead to dispensing failure. Since the dishwasher tablet dispenser of the present invention dispenses dishwasher tablets vertically, the solution of the present invention solves this problem and is applicable to dishwasher tablets of various sizes. By combining the sealing on the side of the discharge port according to the present invention with the push rod drive structure, the impact of push rod stroke error on the sealing effect can be reduced. In contrast, if conventional end-face sealing (i.e., sealing on the plane of the discharge port) is used, the sealing effect is directly determined by the push rod stroke; errors in the push rod stroke will directly and adversely affect the sealing effect. Furthermore, the push rod can be driven by any suitable gear rack or worm gear to achieve linear reciprocating motion in the vertical direction, thereby achieving self-locking of the transmission mechanism and improving transmission efficiency.

[0046] More preferably, the present invention also provides an embodiment in which the material dispensing mechanism and the sealing assembly opening and closing mechanism are linked. See also Figure 5 The push rod 32 includes a drive portion 320. This drive portion 320 may, for example, be a cylindrical protrusion located at the end of the push rod 32. The sealing cap body 21 includes a driven boss 215 extending perpendicularly from the inner surface 214 of the sealing cap body 21, and the driven boss 215 includes a guide groove 216 formed on a surface of the driven boss 215 perpendicular to the pivot axis 20. The guide groove 216 includes at least a first segment 217 and a second segment 218. When viewed in the closed position, the first segment 217 extends substantially parallel to the horizontal direction, i.e., substantially perpendicular to the pushing direction of the push rod 32. This arrangement allows the sealing cap assembly to be positioned more accurately during sealing, preventing excessive tilting when the sealing cap assembly wobbles left or right due to manufacturing errors. The second segment 218 extends from the first end 2171 of the first segment 217. The first end 2171 of the first segment 217 is further away from the pivot axis 20 than the second end 2172 of the first segment 217. The drive unit 320 is disposed within the guide groove 216 of the driven boss 215 so that the sealing cover assembly 2 can be driven by the push rod 32, which reciprocates vertically, to pivot between the open and closed positions, as shown below. Figure 2 and 6 As shown.

[0047] Specifically, from Figure 2and 6 Starting from the closed position shown in the left-hand diagram, the push rod 32 is pushed downwards vertically under the drive of the actuator. The drive unit 320 located in the guide groove 216 of the sealing cover body 21 pushes the sealing cover body 21 to pivot downwards until... Figure 2 and 6 The diagram on the right shows the open position, with the dishwasher tablet falling from the open outlet 1. Subsequently, as the push rod 32 is pulled vertically upwards by the actuator, the drive unit 320 in the guide groove 216 of the sealing cover body 21 pulls the sealing cover body 21 upwards and pivots it until it returns to the closed position. During this cycle of the push rod 32, the storage bin (not shown) in the storage section 30 for storing dishwasher tablets also rotates, so that when the sealing cover body 21 closes the outlet 1 again, a new dishwasher tablet has rotated above the outlet 1, ready for dispensing.

[0048] More preferably, when viewed from the closed position, both the first segment 217 and the second segment 218 extend approximately horizontally. Alternatively, when viewed from the closed position, the second segment 218 extends upwards at an angle relative to the first segment 217. That is, there can be an angle greater than or equal to 0° between the first segment 217 and the second segment 218, which can be optimized based on the installation space of the sealing cap assembly, the push rod stroke, etc. For example, preferably, when the second segment 218 is tilted at an appropriate angle relative to the first segment 217, the volume of the sealing cap body 21 can be reduced, making the related structure more compact. The tilt angle is preferably 30°-60°, more preferably 45°.

[0049] It should be understood that, in the simplest case, the dishwasher tablet can fall directly from the discharge port 1 after the sealing cap assembly 2 is opened. However, according to some other preferred embodiments of the invention, such as... Figure 7 and 8 The housing 3 may also include a dispensing section 33, which, for example, is used to guide the dishwashing tablets falling from the outlet 1 in a desired direction. The dispensing section 33 is located below the storage section 30, and the storage section 30 is connected to the dispensing section 33 via the outlet 1, so that the dishwashing tablets falling from the outlet 1 will be dispensed through the dispensing section 33.

[0050] More preferably, the dispensing section 33 may include a sliding channel 330 communicating with and extending downward from the discharge port 1, a channel outlet 332, and a movable cover 331 covering the channel outlet 332. The channel outlet 332 is arranged, for example, generally vertically, or in other words, located in a plane generally parallel to the vertical direction. This ensures that the dishwasher tablets falling vertically from the discharge port 1 are ultimately dispensed laterally, making it easier to place them at the desired position in the dishwasher. Of course, it is understood that in different embodiments, the channel outlet 332 may also be inclined to a certain degree relative to the vertical direction.

[0051] More preferably, when the movable cover 331 is provided, its upper edge 3310 can be pivotally connected to the upper edge (not shown) of the sliding channel 330 via a pivot, allowing it to pivot between a vertical position with the channel outlet 332 closed and an inclined position with the channel outlet 332 open. With this pivoting opening and closing structure of the movable cover 331, when the dishwasher tablet slides from the sliding channel 330 to the channel outlet 332, the movable cover 331 is pushed open by the dishwasher tablet, allowing it to fall into the dishwasher from the outlet 332. The movable cover 331 also prevents water or foreign objects from entering the dispensing section 33.

[0052] Additionally, the storage section 30 may include a cover 301 that can be opened and closed. The cover 301 can be suitably installed into the storage section 30 and remain sealed in the closed state, so that when the cover 301 is opened or removed, the storage bin for storing dishwashing tablets can be exposed for adding dishwashing tablets.

[0053] The exemplary embodiments of the present invention have been described in detail above with reference to preferred embodiments. Those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
