Description

Technical Field

[0001] This utility model relates to a soap dispenser assembly, and more particularly to a soap dispenser assembly that can be directly installed on a washbasin surface to accommodate long-term use and provide a stable liquid supply. Background Technology

[0002] Commercially available detergents and personal care products, such as hand soap, dish soap, shampoo, shower gel, and facial cleanser, often use soap dispensers for easy access and dispensing. These dispensers typically consist of a storage bottle and a mounting bracket. The storage bottle stores and replaces the detergent, while the bracket secures the bottle to a wall, as illustrated in Japanese invention patent JP 11197046A. Furthermore, these wall-mounted soap dispensers often have a direct dispensing spout on the storage bottle, eliminating the need for a dedicated soap-pressing mechanism or a soap-suction device.

[0003] However, due to space and aesthetic considerations, the liquid dispenser's reservoir cannot be designed to be large. Furthermore, due to its cantilevered load-bearing structure, the reservoir cannot withstand excessive liquid weight. Therefore, the reservoir is relatively small, and it needs to be refilled or replaced after the limited amount of soap is used up. Moreover, the frequent replacement of the reservoir weakens the stability of the wall-mounted soap dispenser.

[0004] In view of the aforementioned technical problems, German invention patent DE 102012009109A1 provides a soap dispenser structure for mounting on a sink. This structure uses mounting holes on the countertop and a separate threaded connection component, such as a nut, to engage with a thin-walled sleeve with external threads to secure the soap dispenser. This aims to improve functionality and reduce the cost of a separate soap dispenser. Furthermore, this invention patent also incorporates a screw-type thin-walled rotating component integrated with the threaded sleeve for securing the soap dispenser, enabling soap suction. Similarly, Chinese utility model patent CN 201894590U discloses a similar solution that uses a separate locking nut and external threads on a positioning sleeve to lock the soap dispenser. In this Chinese utility model patent, soap suction is achieved through a thin-walled rotating component for locking the soap dispenser.

[0005] In addition, in various patents and technical solutions such as the improved Chinese invention patent CN 109394047 A, a solution is also used to fix the soap dispenser to the countertop by using threaded connectors to provide a soap dispenser bottle with a larger volume, thereby avoiding the occupation of wall space; thus, a liquid storage tank with a larger volume is set at the bottom of the countertop to avoid frequent liquid filling or liquid tank replacement.

[0006] However, threaded connections directly mounted on the countertop, as well as individual threaded connectors, can loosen due to prolonged use or exposure to fluid splashes from the countertop, and parts can be lost due to operator negligence. Furthermore, in the technical solution provided in Chinese Invention Patent CN 110151031 A, which provides soap dispenser through both rotary and axial extrusion, the added ratchet mechanism of the drive block and driven block for rotary extrusion complicates the suction device's structure; on the other hand, the simple connection between the pump body and base for axial extrusion can affect its service life due to structural strength limitations. Therefore, based on the description of the prior art, there is a technical problem of finding alternative methods to install the soap dispenser on the countertop to avoid frequent liquid filling or tank replacement, while simultaneously providing a structurally stable soap dispenser and achieving a stable soap supply.

[0040] Those skilled in the art will understand that the following detailed description of embodiments is merely an illustration of exemplary models and is not intended to limit the broader aspects of this disclosure.

[0041] Figure 1A three-dimensional perspective view of the soap dispenser assembly according to the present invention, connected to a hose and a large-capacity liquid reservoir, is shown. Those skilled in the art will readily recognize that, by means of the delivery pipe 2, the soap dispenser assembly 1 is adapted for long-distance connection to the large-capacity liquid reservoir 3, thereby providing users with a long-term liquid supply service while avoiding the frequent dispensing of soap and the frequent disassembly of the soap dispenser and reservoir required by wall-mounted soap dispensers in the aforementioned prior art.

[0042] Figure 5 and Figure 9 Exploded views of two different non-limiting embodiments of the soap dispenser assembly 1 according to the present invention are shown, illustrating how the soap dispenser assembly can be fixed to a washbasin using a method different from threaded connections presented in the prior art (especially threaded connections in the prior art that expose to fluid media such as tap water). The soap dispenser assembly 1 includes at least a pressing component 10, a suction component 20, and a mounting component. Depending on the specific embodiment, the mounting component may further have at least a construction such as a first mounting component 30 or a second mounting component 40.

[0043] See Figure 2 and Figure 3 The diagram shows a non-limiting cross-sectional view of a pressing component and a suction component of a soap dispenser assembly according to the present invention. The pressing component 10 and the suction component 20 can be applied to different embodiments of the soap dispenser assembly 1 according to the present invention, thereby simplifying the design and manufacturing costs of the soap dispenser assembly 1 according to the present invention with the same design and manufacturing method, and achieving interchangeability of components of the soap dispenser 1 with different mounting assemblies.

[0044] Suction Components

[0045] like Figure 2 As shown, the pressing assembly 10 includes at least a pressing head 110 and a pressing ring 120, thereby enabling the downward axial pressure F to be transmitted to the pressing ring 120 through the pressing head 110, and the soap solution to be supplied to the liquid outlet channel of the pressing head 110 via a channel located inside the pressing ring 120. Further, the pressing ring 120 has a radial pressing surface 121 and an axial pressing surface 122 on its flange portion facing the suction assembly 20, wherein the radial pressing surface 121 and the axial pressing surface 122 partially engage with the suction assembly 20.

[0046] Figure 2The structure of the suction assembly 20 is also shown. The suction assembly 20 has at least a first suction tube 210 and a second suction tube 250. The first suction tube 210 is generally elongated tubular and can be divided from top to bottom into a first suction portion 211, a second suction portion 212, and a third suction portion 213. The first suction portion 211 can be inserted into the flange of the pressing ring 120 in an insertable manner. Furthermore, the outer peripheral surface of the first suction portion 211 is also provided with a plurality of radially outwardly extending circumferential protrusions, which can abut radially against the radial pressing surface 121 of the flange of the pressing ring 120. Furthermore, the first suction portion 211 also has a shoulder that faces the pressing ring 120 and abuts axially against the axial pressing surface 122 of the flange of the suction assembly 20. Therefore, a radial frictional contact and axial compression are formed between the pressing ring 120 and the first suction portion 211 of the first suction tube 210, thereby effectively transmitting the axial pressure F applied to the pressing ring 120 to the suction assembly 20 via the two surfaces.

[0047] The suction assembly 20 also includes a first thrust member 220. The first thrust member 220 is generally collar-shaped and has radially spaced bosses formed on its outer circumferential surface along the axial direction, as shown in the figures: a first radial boss 221 and a second radial boss 212. Further, the first thrust member 220 is provided with a through hole of equal diameter, the through hole having a diameter generally equal to the outer diameter of the second suction portion 212 of the first suction tube 210, so as to generally surround the second suction portion 212 of the first suction tube 210 circumferentially and form a clearance fit with the second suction portion 212. Further, the radial dimension and thickness of the first radial boss 221 of the first thrust member 220 are both greater than those of the second radial boss 222, and it can abut against the first end 231 of the suction sleeve 230 of the suction assembly 20 along the axial direction or radial direction to define its axial position. See [reference needed]. Figure 2 .

[0048] The suction assembly 20 also includes a second thrust member 240. The second thrust member 240 is generally collar-shaped, and a third radial boss 241 with a radially reduced dimension is formed on its inner circumferential surface. The second thrust member 240 is also configured with a third end 242 that radially surrounds the outer periphery of the third suction portion 213 of the first suction tube 210. Further, the third end 242 is configured with a clearance fit radially with the third suction portion 213 of the first suction tube 210.

[0049] Further, see Figure 3The second radial boss 222 of the first thrust member 220 abuts the upward end face of the shoulder at the third suction part 213 of the first suction tube 210 in the axial direction, and the third end 242 of the second thrust member 240 abuts the downward end face of the shoulder at the third suction part 213 of the first suction tube 210 in the axial direction. Thus, the first wall thickness S1 of the first suction tube 210 and the second wall thickness S2 of the first thrust member 220 are superimposed at the part where the first suction tube 210 and the first thrust member 220 move relative to each other in the axial direction, and the sliding contact surface of the first suction tube 210 along the first thrust member 220 is further increased. Additionally, at the location where the first suction tube 210 and the second thrust member 240 move axially relative to each other, the third wall thickness S3 of the first suction tube 210 and the fourth wall thickness S4 of the second thrust member 240 are superimposed, so that the first suction tube 210 and the second thrust member 240, which move axially at the same time, form a wall thickness in the second suction section 212 of the first suction tube 210 that is approximately more than twice the fourth wall thickness S4 of the first suction tube 210.

[0050] The suction assembly 20 also includes a second suction tube 250. The second suction tube 250 has a fourth suction section 251 located radially close to the third suction section 213 of the first suction tube 210, and a fifth suction section 252 and a sixth suction section 253 sequentially located axially away from the third suction section 213 of the first suction tube 210. The fourth suction section 251, the fifth suction section 252, and the sixth suction section 253 are arranged in a stepped manner and have sequentially increasing outer diameter dimensions.

[0051] Further, see Figure 2 and Figure 3 The third end 242 of the second thrust member 240, the third suction portion 213 of the first suction tube 210, and the fourth suction portion 251 of the second suction tube 250 can be radially superimposed with a third wall thickness S3, a fourth wall thickness S4, and a fifth wall thickness S5. It is noteworthy that in this invention, the first suction tube 210, the second thrust member 240, and the second suction tube 250 move synchronously under axial pressure F. Furthermore, the first depth L1 formed by the superposition of the first suction tube 210, the first thrust member 220, the second suction tube 250, and the second thrust member 240 generally exceeds half of the total liquid-accommodating depth L of the suction sleeve 230. This ensures the radial rigidity of the moving parts in the suction assembly 20 during synchronous movement and further ensures a larger contact area between the first suction tube 210 and the second suction tube 250 and the suction sleeve 230 during axial movement, thereby achieving stable movement.

[0052] According to another aspect of the present invention, in order to achieve liquid suction, a radially clearance-fitted portion 213 of the first suction tube 210 and the fourth suction portion 251 of the second suction tube 250, particularly at the top end of the fourth suction portion 251 of the second suction tube 250, can be constructed with an internally conical discharge port 254 for accommodating the first ball valve 260. (See also...) Figure 2 and Figure 3 .

[0053] The suction assembly 20 also includes a suction sleeve 230. As described above, the first end 231 of the suction sleeve 230 can abut against the first radial boss 221 of the first thrust member 220 in the axial and / or radial directions, and can be fastened to the first thrust member 220 there. The second end 232 of the suction sleeve 230 has a generally cylindrical inner bore and an inner conical inlet 233, wherein the inner cylindrical portion of the second end 232 of the suction sleeve 230 accommodates an elastic member 270. Figure 2 The spring is shown as a compression spring, while the cone-shaped inlet 233 houses the second ball valve 280. See also... Figure 3 Given the maximum compression ratio of 40% of the compression spring, when subjected to axial pressure F, the third suction section 213 of the first suction tube 210 can drive the second thrust member 240 and the second suction tube 250 to move linearly in the axial direction toward the second ball valve 280. At the same time, the second thrust member 240 and the second suction tube 250 simultaneously compress the elastic member 270 axially to the vertical height position of the second convex rib group 2321 in the second end 232 of the generally suction sleeve 230, that is, a distance of approximately a third depth L3 relative to the maximum conical surface of the liquid inlet 233. Thus, liquid is drawn in by means of the suction space with a third depth L3 and a second orifice D2 in the second end 232 of the suction sleeve 230. This suction space is generally cylindrical and occupies approximately 25%-30% of the internal space of the suction sleeve 230.

[0054] Furthermore, the axial movement distance of the first ball valve 260 is L2, which is at most 1 / 3 of the first depth L1 formed by the superposition of the first suction tube 210, the first thrust member 220, the second suction tube 250, and the second thrust member 240, and does not exceed the suction depth, i.e., 1 / 2 of the third depth L3. Furthermore, the radial movement distance of the first ball valve 260 is the first orifice diameter D1, and the size of the first orifice diameter D1 is at most 1 / 3 of the second orifice diameter D2, thereby constraining the drainage space. This drainage space is much smaller than the suction space with the third depth L3 and the second orifice diameter D2 within the second end 232 of the suction sleeve 230, thereby effectively controlling and limiting the axial flow distance of the liquid towards the first suction section 211 of the first suction tube 210, thus slowing down the liquid flow, especially the discharge speed.

[0055] Figure 3 The cross-sections of the first suction tube 210, the second thrust member 240, and the second suction tube 250, arranged radially with a clearance fit according to a non-limiting embodiment of the present invention, are also shown by red dashed lines. When the first suction tube 210, the second thrust member 240, and the second suction tube 250 move axially toward the second ball valve 280, they form a large cross-section for synchronous movement, namely the superposition of the third wall thickness S3, the fourth wall thickness S4, and the fifth wall thickness S5 mentioned above, thereby ensuring the rigidity of the moving parts of the suction assembly 20 during movement. Specifically, the wall thickness of the moving parts formed by the first suction tube 210, the second thrust member 240, and the second suction tube 250 during synchronous movement is at least three times the third wall thickness S3 of the first suction tube 210. Furthermore, the outer peripheral surface of the suction sleeve 230 is also provided with a first convex rib group 2311 along the axial direction to ensure that the suction sleeve 230 is tightly engaged with components such as sleeves or flanges in the soap dispenser assembly in the radial and axial directions, and to further enhance the overall rigidity of the soap dispenser assembly.

[0056] Installation components

[0057] Figures 4 to 6 A non-limiting embodiment of the mounting assembly according to the present invention is shown, hereinafter referred to as the first mounting assembly 30; while Figures 7 to 10 Another non-limiting embodiment of the mounting assembly according to the present invention is shown, hereinafter referred to as the second mounting assembly 40.

[0058] First installation component

[0059] See Figure 5 In a first non-limiting embodiment according to the present invention, the first suction portion 211 of the suction assembly 20 first radially engages with the pressing assembly 10. Subsequently, the suction assembly 20 is inserted into the first flange 310 and connected to a radial step provided within the first flange 310 via the first radial boss 221 of the first thrust member 220 in the suction assembly 20, preferably by a fastening method, as can be seen in [reference needed]. Figure 2 The main body of the suction assembly 20 then enters the first mounting tube 320, and the suction assembly 20 and the first mounting tube 320 are connected as a whole by means of the first flange 310, the base 330 and the gasket 340. In particular, the outer surface of the first mounting tube 320 is also provided with threads, so the first fastening nut 361 of the first fastening assembly 360 and the first lateral stop member 380 with internal threads can be screwed at intervals to the end of the first mounting tube 320 away from the first flange 310.

[0060] The first fastening assembly 360 is configured to have at least a first fastening nut 361 and a pair of first flaps 362, wherein each first flap 362 is symmetrically disposed on the outer peripheral surface of the first fastening nut 361 and pivotally connected to the outer peripheral surface of the first fastening nut 361. Specifically, each first flap 362 has a first wing portion 3621 and a second wing portion 3622, wherein the second wing portion 3622 has a length significantly greater than that of the first wing portion 3621; specifically, the length of the second wing portion 3622 is at least 2 / 3 of the length of the first flap 362. Additionally, the first fastening nut 361 also has a pair of first through holes 3611 on its base. These first through holes 3611 are axially arranged on the base of the first fastening nut 361 and symmetrically arranged with respect to the central axis of the first fastening nut 361, and are respectively close to the second wing portion 3622 of each first flap 362.

[0061] A first support 370 is further provided between the first fastening assembly 360 and the first transverse stop 380. This first support 371 is generally annular and has only a smooth inner bore surface. The first support 370 also has a pair of support stops 372 disposed on its outer circumferential surface. These support stops 372 are generally triangular in shape and symmetrically arranged with respect to the central axis of the first support 370. Specifically, the inclined side 3721 of each support stop 372 can respectively abut against the generally downward-pointing first wing side 3623 of each first wing 362. Additionally, the first support 370 also has a pair of second through holes 3711 on its support body 371. These second through holes 3711 are symmetrically arranged with respect to the central axis of the first support 370 and are respectively close to each support stop 372. Specifically, each of the second through holes 3711 of the first support 370 corresponds one-to-one with each of the first through holes 3611 of the first fastening nut 361, that is, they each have a common central axis.

[0062] Based on this structure, a pair of first guide rails 350 can be connected to the first flange 310 and the first support 370 respectively through the first through hole 3611 of the first fastening component 360 and the second through hole 3711 of the first support 370, forming an integrated soap dispenser assembly 1 that has both suction and installation functions.

[0063] In view of this, such as Figure 6As shown, the first mounting assembly 30 has a first operating state, in which the first wing side 3623 of each first wing 362 of the first fastening assembly 360 abuts against the inclined side 3721 of the support stop 372 of the first support 370. In this first operating state, the soap dispenser assembly 1 can be installed in the through hole opened on the washbasin surface. Further, by screwing the first mounting tube 320, the operator can raise and lower the first fastening assembly 360 along the external thread of the first mounting tube 320 to adjust the distance between the first flange 310 and the first fastening assembly 360 based on the thickness of the washbasin surface. When the distance between the first flange 310 and the first fastening assembly 360 is approximately equal to the thickness of the washbasin surface, the operator can continue to screw the first mounting tube 320 to raise it upwards. Since the second wing 3622 of each first wing 362 of the first fastening assembly 360 is significantly longer than the first wing 3621, during the tightening process, due to gravity, each first wing 362 begins to pivot toward the second wing 3622, so that each first wing 362 is parallel to the washbasin surface. The operator can then climb upwards by further tightening the first mounting tube 320, so that the first flange 310 of the soap dispenser assembly 1 and each first wing 362 of the first fastening assembly 360 together clamp the washbasin. Thus, the integrated structure of the soap dispenser assembly 1 provides a different installation method from that of the prior art, which uses separate threaded connection components.

[0064] Second installation component

[0065] See Figure 7 In a second non-limiting embodiment of the present invention, unlike the aforementioned first mounting assembly 30 which only has a single first mounting tube 320, the second mounting assembly 40 has a second mounting tube assembly 420 that includes at least a first side tube 421 and a second side tube 422. The first end 231 of the suction sleeve 230 in the suction assembly 20 axially abuts against the end of the second side tube 422. The peripheral wall 4221 of the second side tube partially accommodates the suction sleeve 230 in the suction assembly 20, and the suction sleeve 230 and the second side tube 422 are circumferentially joined by a first convex rib group 2311 constructed on the outer peripheral wall of the suction sleeve 230, thereby integrating the suction assembly 20 and the second mounting assembly 40 into one unit and constructing a more reinforced connection structure. See [link to relevant documentation]. Figure 10 .

[0066] See Figure 8 The second side tube 422 can also be partially nested within the first side tube 421 to construct a second mounting tube assembly 420 with a generally double wall thickness, thereby giving the second mounting tube assembly 420 higher strength relative to the first mounting assembly 30.

[0067] Specifically, the upper end 4221 of the second side tube is embedded into the upper end 4211 of the first side tube, and together with the engaging ring 430 and the engaging washer 440, they form a support portion for the second guide rail 450, as can be seen in [reference needed]. Figure 7 The second guide rail 450 is shown. Further, the first side tube 421 has a first stop portion 460 directly constructed at its portion near the lower end 4212 of the first side tube. This first stop portion 460 extends from the outer periphery of the first side tube 422 generally in a direction transverse to the central axis of the second side tube 422, thus constructing a pair of first lateral stops 4611 symmetrically arranged with respect to the central axis of the second side tube 422. This pair of first lateral stops 4611 is integrally constructed with the first transverse stop portion 4612 near the lower end 4212 of the first side tube. The first transverse stop portion 4612 can also be used to fix and support the second guide rail 450, as shown in [reference]. Figure 8 .

[0068] Additionally, a second stop portion 470 is also constructed near the lower end 4222 of the second side tube. Similar to the configuration of the first stop portion 460, this second stop portion 470 is constructed in the same manner as the second lateral stop portion 4711 and the second transverse stop portion 4712, as can be seen in [reference needed]. Figure 8 However, the upper end 4221 of the second side tube is constructed to have a smaller geometric dimension than the upper end 4211 of the first side tube, and the lower end 4222 of the second side tube also has a smaller geometric profile than the lower end 4212 of the first side tube. Specifically, the second side tube 422 is constructed to have a significantly smaller axial dimension than the first side tube 421, and the first side tube 421 has a slot at its lower end 4212, allowing the second side tube 422 to be inserted into the first side tube 421 from bottom to top along its central axis. Furthermore, the second stop portion 470 of the second side tube 422 can also be inserted into the first stop portion 460 of the first side tube 421 in a mating manner. See [reference needed]. Figure 8 This forms a reinforced second mounting tube assembly 420.

[0069] The second mounting assembly 40 is also equipped with a second fastening assembly 480, see below. Figures 8-10 The second fastening assembly 480 is configured to have at least a second fastening nut 481 and a pair of second flaps 482. Each second flap 482 is symmetrically disposed on the outer peripheral surface of the second fastening nut 481 and is pivotally connected to the outer peripheral surface of the second fastening nut 481. Specifically, each second flap 482 has a third flap 4821 and a fourth flap 4822, wherein the fourth flap 4822 has a significantly longer length than the third flap 4821. Specifically, the length of the fourth flap 4822 is at least 2 / 3 of the length of the second flap 482. Further, the second fastening nut 481 in the second fastening assembly 480 is threadedly connected to the second guide rail 450 (which has external threads) to form an integrated assembly.

[0070] In view of this, such as Figure 10 As shown, the second mounting assembly 40 also has a first operating state, in which the second wing sides 4823 of each second wing 482 of the second mounting assembly 40 abut against the first lateral stop portion 4611. In this first operating state, the soap dispenser assembly 1 can be installed in the through hole opened on the washbasin surface. Further, by turning the second guide rail 450, the operator can make the second fastening assembly 480 climb along the external thread of the second guide rail 450 to adjust the distance between the second flange 410 and the second fastening assembly 480 based on the thickness of the washbasin surface. When the distance between the second flange 410 and the second fastening assembly 480 is approximately equal to the thickness of the washbasin surface, the operator can continue to turn the second guide rail 450. Since the fourth wing 4822 of each second wing 482 in the second fastening assembly 480 has a significantly longer length than the third wing 4821, during the tightening process, due to gravity, each second wing 482 begins to pivot toward the fourth wing 4822, so that each second wing 482 is parallel to the washbasin surface. The operator can then further tighten the second guide rail 450 to make the second flange 410 of the soap dispenser assembly 1 and each second wing 482 of the second fastening assembly 480 move together toward the washbasin and clamp the washbasin. Thus, the integrated structure of the soap dispenser assembly 1 provides a different installation method from that of the prior art, which uses separate threaded connection parts.

[0071] On the other hand, the soap dispenser assembly 1 according to this utility model also has a third operating state suitable for drawing in soap solution and a fourth operating state suitable for discharging liquid. In the third operating state, the third suction part 213 of the first suction tube 210 drives the second thrust member 240 and the second suction tube 250, and compresses the elastic member 270 axially towards the second ball valve 280, thereby drawing soap solution into the suction sleeve. In the fourth operating state, the elastic member 270 extends axially and drives the second suction tube 250, which pushes the second thrust member 240 and the third suction part 213 of the first suction tube 210 away from the second ball valve 280 in a linear motion, thereby delivering soap solution to the discharge space.

[0072] Furthermore, based on the aforementioned construction of the suction component 20 and the sleeve configuration of the first mounting component 30 connected thereto or the sleeve configuration of the second mounting component 40 connected to the suction component 20, the integrated soap dispenser component 1 provided by this utility model has greater static and dynamic rigidity than the prior art, and also takes into account the stability of the suction process.
