Description

Technical Field

[0001] The present invention relates to a soap dispenser assembly, in particular to a soap dispenser assembly which can be directly mounted on a washstand surface to adapt to long-term use and stable liquid supply. Background Art

[0002] Commonly used washing supplies and personal care products on the market, such as hand soap, dishwashing liquid, shampoo, shower gel, facial cleanser, etc., are often stored and discharged in a soap dispenser for easy access. The soap dispenser usually includes a liquid storage bottle and a mounting bracket. The liquid storage bottle is used to store and replace the detergent, and the mounting bracket is used to fix the liquid storage bottle on the wall, such as Japanese invention patent JP 11197046A. Furthermore, this wall-mounted soap dispenser usually has a liquid outlet directly set on the liquid storage bottle, so there is no need for a special soap pressing mechanism or soap liquid suction device.

[0003] However, for the sake of space and aesthetics, the liquid storage bottle of the soap dispenser mounted on the wall cannot be designed to have a large volume, and further, due to the cantilever load-bearing structure, the liquid storage bottle of the soap dispenser cannot bear too much liquid weight, so the liquid storage bottle is small in volume, and after the limited soap liquid is used up, the soap liquid needs to be refilled or replaced. Furthermore, the frequent replacement of the liquid storage bottle also weakens the stability of the soap dispenser mounted on the wall.

[0004] In view of the above technical problems, German invention patent DE 102012009109A1 provides a soap dispenser structure installed on a sink, which is fixed to the countertop by setting a mounting hole on the countertop and using a separate threaded connection component, such as a nut and a thin-walled sleeve with an external thread, to improve its functionality and reduce the cost of setting up a soap dispenser separately. In addition, the invention patent also constructs a screw-type thin-walled rotating part that is integrated with the external threaded sleeve for fastening the soap dispenser to achieve the suction of soap liquid. Further, Chinese utility model patent CN 201894590U also discloses a similar technical solution for locking the soap dispenser by an independent clamping nut and an external thread constructed on a positioning sleeve. Further, in the Chinese utility model patent, the suction of soap liquid is achieved by a thin-walled rotating part 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 soap dispenser is fixed to the countertop by using a threaded connector to provide a soap bottle with a larger volume, thereby avoiding occupying 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 tank replacement.

[0006] However, the threaded connection structure directly constructed on the table top and the separate threaded connection parts may also cause the threaded fitting to loosen due to long-term use or erosion by the fluid splashed from the table top, and parts may be lost due to negligence of the operator. Furthermore, in the technical solution for providing soap liquid by both rotary extrusion and axial extrusion, as provided in Chinese invention patent CN 110151031 A, on the one hand, the additional ratchet structure of the driving block and the driven block for rotary extrusion makes the structure of the suction device more complicated; on the other hand, the simple connection between the pump body and the base for axial extrusion will also affect its service life due to its structural strength. Therefore, in view of the description of the prior art, there is a technical problem of realizing the installation of the soap dispenser on the table top by other means to avoid frequent liquid filling or liquid tank replacement, and at the same time provide a soap dispenser with a stable structure and achieve stable soap liquid supply.

[0020] Those skilled in the art will appreciate that the following description of the detailed embodiments is merely illustrative of exemplary embodiments and is not intended to limit the broader aspects of the present disclosure.

[0021] Figure 1 The three-dimensional perspective view of the soap dispenser assembly according to the present invention connected with the hose and the large-capacity liquid storage tank is shown. It can be known to those skilled in the art that, by means of the delivery tube 2, the soap dispenser assembly 1 is suitable for long-distance connection with the large-capacity liquid storage tank 3, so as to provide users with long-term liquid supply service, and at the same time avoid the frequent infusion of soap liquid and the frequent disassembly of the soap dispenser and the liquid storage tank required by the wall-mounted soap dispenser in the prior art.

[0022] Figure 5 Two different non-limiting embodiments of the soap dispenser assembly 1 according to the present invention are shown in exploded views, so as to fix the soap dispenser assembly to the washstand by a threaded connection method different from that presented in the prior art (especially the threaded connection method in the prior art that is exposed to a fluid medium such as tap water). The soap dispenser assembly 1 at least includes a pressing assembly 10, a suction assembly 20 and a mounting assembly. According to different specific embodiments, the mounting assembly may further have at least a first mounting assembly 30 or a second mounting assembly 40.

[0023] See also Figure 2 and Figure 3, which shows a cross-sectional view of a non-limiting embodiment of a pressing assembly and a suction assembly of a soap dispenser assembly according to the present invention. The pressing assembly 10 and the suction assembly 20 can be applied to different embodiments of the soap dispenser assembly 1 according to the present invention, so that the design and manufacturing costs of the soap dispenser assembly 1 according to the present invention can be simplified by the same design and manufacturing method, and the parts interchangeability of the soap dispenser 1 with different mounting components can be achieved.

[0024] Suction components like Figure 2 As shown, the pressing assembly 10 at least includes a pressing head 110 and a pressing ring 120, so that the downward axial pressure F can be transmitted to the pressing ring 120 through the pressing head 110, and the soap liquid is supplied to the liquid outlet channel of the pressing head 110 through the channel located inside the pressing ring 120. Further, the pressing ring 120 is further provided with a radial pressing surface 121 and an axial pressing surface 122 at the flange portion facing the suction assembly 20, wherein the radial pressing surface 121 and the axial pressing surface 122 are partially engaged with the suction assembly 20.

[0025] Figure 2 The 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 in an elongated tubular configuration, and can be divided into a first suction portion 211, a second suction portion 212 and a third suction portion 213 from top to bottom. Among them, the first suction portion 211 can partially enter the flange portion of the pressing ring 120 in a plug-in manner. Further, the outer peripheral surface of the first suction portion 211 is also configured with a plurality of circumferential protrusions extending radially outward, and the plurality of circumferential protrusions can radially abut against the radial pressing surface 121 of the flange portion of the pressing ring 120. Further, the first suction portion 211 also has a shoulder, which faces the pressing ring 120 and axially abuts against the axial pressing surface 122 of the flange portion of the suction assembly 20. In view of this, radial friction contact and axial compression are constructed between the pressing ring 120 and the first suction portion 211 of the first suction pipe 210 , so that the axial pressure F applied to the pressing ring 120 is effectively transmitted to the suction assembly 20 via two surfaces.

[0026] The suction assembly 20 also includes a first thrust member 220. The first thrust member 220 is generally in the shape of a collar, and radial bosses spaced apart from each other are formed on its outer circumferential surface in the axial direction, which are shown as a first radial boss 221 and a second radial boss 212. Further, the first thrust member 220 is provided with an equal-diameter through hole, which has 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 in the circumferential direction, and form a clearance fit with the second suction portion 212. Further, the radial size 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 can abut against the first end 231 of the suction sleeve 230 of the suction assembly 20 in the axial or radial direction to limit its axial position, see. Figure 2 .

[0027] The suction assembly 20 further includes a second thrust member 240. The second thrust member 240 is generally in the shape of a collar, and a third radial boss 241 with a reduced radial dimension is formed on its inner circumference. The second thrust member 240 is also configured with a third end portion 242 that radially surrounds the outer circumference of the third suction portion 213 of the first suction pipe 210. Further, the third end portion 242 and the third suction portion 213 of the first suction pipe 210 are configured with a clearance fit in the radial direction.

[0028] Further, see Figure 3 The second radial boss 222 of the first thrust member 220 axially abuts against the upward end surface of the axial shoulder at the third suction portion 213 of the first suction pipe 210, and the third end portion 242 of the second thrust member 240 axially abuts against the downward end surface of the axial shoulder at the third suction portion 213 of the first suction pipe 210, thereby superimposing the first wall thickness S1 of the first suction pipe 210 and the second wall thickness S2 of the first thrust member 220 at the position where the first suction pipe 210 and the first thrust member 220 move axially relative to each other, and further increasing the sliding contact surface of the first suction pipe 210 along the first thrust member 220. In addition, 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 at the portion where the first suction tube 210 and the second thrust member 240 move axially relative to each other, so that the first suction tube 210 and the second thrust member 240 that move axially at the same time form a wall thickness in the second suction portion 212 of the first suction tube 210 that is substantially more than twice the fourth wall thickness S4 of the first suction tube 210.

[0029] The suction assembly 20 further includes a second suction pipe 250. The second suction pipe 250 is provided with a fourth suction portion 251 at a position radially close to the third suction portion 213 of the first suction pipe 210, and is provided with a fifth suction portion 252 and a sixth suction portion 253 in sequence at a position axially away from the third suction portion 213 of the first suction pipe 210. The fourth suction portion 251, the fifth suction portion 252 and the sixth suction portion 253 are arranged in a stepped manner and have outer diameters that increase in sequence.

[0030] Further, see Figure 2 and Figure 3 , the third end 242 of the second thrust piece 240, the third suction portion 213 of the first suction pipe 210 and the fourth suction portion 251 of the second suction pipe 250 can form a superposition of the third wall thickness S3, the fourth wall thickness S4 and the fifth wall thickness S5 in the radial direction. It is worth noting that in the present invention, the first suction pipe 210, the second thrust piece 240 and the second suction pipe 250 will move synchronously under the action of the axial pressure F. Further, the first depth L1 formed by the superposition of the first suction pipe 210 and the first thrust piece 220, the second suction pipe 250 and the second thrust piece 240 is substantially greater than 1 / 2 of the total depth L of the liquid that can be accommodated by the suction sleeve 230, so that the radial rigidity of each moving part in the suction assembly 20 in the synchronous movement can be ensured on the one hand, and the first suction pipe 210 and the second suction pipe 250 can further ensure that the first suction pipe 210 and the second suction pipe 250 are in contact with the suction sleeve 230 in a larger area during the axial movement, thereby achieving stable movement.

[0031] According to another aspect of the present invention, in order to achieve the suction of liquid, a drain port 254 in the shape of an inner cone can be constructed at the radial clearance fit between the third suction portion 213 of the first suction pipe 210 and the fourth suction portion 251 of the second suction pipe 250 in the suction assembly 20, especially at the top end of the fourth suction portion 251 of the second suction pipe 250, for accommodating the first ball valve 260, see Figure 2 and Figure 3 .

[0032] The suction assembly 20 further includes a suction sleeve 230. As described above, the first end 231 of the suction sleeve 230 may abut against the first radial boss 221 of the first thrust member 220 in the axial direction and / or radial direction, and may be fastened to the first thrust member 220 there. The second end 232 of the suction sleeve 230 has, on one hand, an inner hole portion that is generally cylindrical, and, on the other hand, an inner conical liquid inlet 233, wherein the inner cylindrical portion of the second end 232 of the suction sleeve 230 accommodates the elastic component 270, Figure 2 The compression spring is shown, and the inlet 233 with an inner cone shape accommodates the second ball valve 280, see Figure 3In view of the maximum compression ratio of the compression spring of 40%, when the third suction portion 213 of the first suction pipe 210 moves under the axial pressure F, the second thrust piece 240 and the second suction pipe 250 can drive the second thrust piece 240 and the second suction pipe 250 to move linearly in the axial direction toward the second ball valve 280, and the second thrust piece 240 and the second suction pipe 250 simultaneously axially squeeze the elastic component 270 to the longitudinal height position of the second ridge group 2321 in the second end portion 232 of the suction sleeve 230, that is, the distance substantially spaced by the third depth L3 relative to the maximum conical surface of the liquid inlet 233, so that the liquid is sucked in by means of the suction space having the third depth L3 and the second aperture D2 in the second end portion 232 of the suction sleeve 230, the suction space being substantially cylindrical and substantially occupying 25%-30% of the internal space of the suction sleeve 230.

[0033] 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 pipe 210 and the first thrust member 220, the second suction pipe 250 and the second thrust member 240, and does not exceed the suction depth, that is, 1 / 2 of the third depth L3. Furthermore, the radial movement distance of the first ball valve 260 is the first aperture D1, and the size of the first aperture D1 is at most 1 / 3 of the second aperture D2, thereby constraining the drainage space. The drainage space is much smaller than the suction space with the third depth L3 and the second aperture D2 in the second end 232 of the suction sleeve 230, so that the flow distance of the liquid in the axial direction toward the first suction portion 211 of the first suction pipe 210 can be effectively controlled and limited to slow down the flow of the liquid, especially the discharge speed.

[0034] Figure 3 The cross-section of the first suction pipe 210, the second thrust piece 240 and the second suction pipe 250 arranged in a radially clearance-fitting manner according to a non-limiting embodiment of the present invention is also shown by a red dotted line, wherein the first suction pipe 210, the second thrust piece 240 and the second suction pipe 250, when moving axially toward the second ball valve 280, construct a larger cross-section of synchronous movement, i.e., 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 the movement process. In particular, the wall thickness of the moving parts constructed by the first suction pipe 210, the second thrust piece 240 and the second suction pipe 250 during synchronous movement is at least 3 times the third wall thickness S3 of the first suction pipe 210. Furthermore, the outer peripheral surface of the suction sleeve 230 is also axially provided with a first ridge group 2311 to ensure the tight radial and axial engagement of the suction sleeve 230 with components such as a sleeve or a flange in the soap dispenser assembly, and to further enhance the overall rigidity of the soap dispenser assembly.

[0035] Installing Components Figures 4 to 6 A non-limiting embodiment of a mounting assembly according to the present invention is shown, hereinafter referred to as a first mounting assembly 30; and Figures 7 to 10 Another non-limiting embodiment of a mounting assembly according to the present invention is shown, hereinafter referred to as a second mounting assembly 40 .

[0036] First install the components See also Figure 5 In a first non-limiting embodiment according to the present invention, the first suction portion 211 of the suction assembly 20 is first radially engaged with the pressing assembly 10. Then, the suction assembly 20 is inserted into the first flange 310, and the first radial boss 221 of the first thrust member 220 in the suction assembly 20 is connected to the radial step provided in the first flange 310, preferably by fastening, as can be seen in 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 plate 330 and the gasket 340. In particular, the outer surface of the first mounting tube 320 is also provided with threads, so that the first fastening nut 361 of the first fastening assembly 360 and the first transverse stopper 380 with internal threads can be screwed to the end of the first mounting tube 320 away from the first flange 310 at intervals from each other.

[0037] The first fastening assembly 360 is configured to have at least a first fastening nut 361 and a pair of first fins 362, wherein each first fin 362 is symmetrically arranged on the outer peripheral surface of the first fastening nut 361 and is pivotally connected to the outer peripheral surface of the first fastening nut 361. In particular, each first fin 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 the first wing portion 3621; in particular, the length of the second wing portion 3622 is at least 2 / 3 of the length of the first wing portion 362. In addition, the first fastening nut 361 is further provided with a pair of first through holes 3611 on its base. The pair of first through holes 3611 are arranged axially on the base of the first fastening nut 361, and are symmetrically arranged relative to the central axis of the first fastening nut 361, and are respectively close to the second wing portion 3622 of each first fin 362.

[0038] A first support 370 is further provided between the first fastening assembly 360 and the first transverse stopper 380. The first support 371 is generally annular and has only a smooth inner hole surface. The first support 370 also has a pair of support stoppers 372 arranged on its outer circumference. The pair of support stoppers 372 are generally in a triangular plate shape and are symmetrically arranged relative to the central axis of the first support 370. In particular, the inclined side 3721 of each support stopper 372 can respectively abut against the first wing side 3623 of each first wing 362 that is generally directed downward. In addition, the first support 370 is further provided with a pair of second through holes 3711 on its support body 371. The pair of second through holes 3711 are symmetrically arranged relative to the central axis of the first support 370 and are respectively close to each support stopper 372. In particular, the second through holes 3711 of the first support 370 correspond one-to-one to the first through holes 3611 of the first fastening nut 361 , that is, they respectively have a common central axis.

[0039] Based on this structure, a pair of first guide rails 350 can be connected between the first flange 310 and the first support 370 via the first through hole 3611 of the first fastening assembly 360 and the second through hole 3711 of the first support 370, respectively, to form an integrated soap dispenser assembly 1 with both suction and installation functions.

[0040] In view of this, if Figure 6 As shown, the first mounting assembly 30 has a first operating state, that is, the first wing side 3623 of each first wing 362 of the first fastening assembly 360 respectively abuts against the inclined side 3721 of the support stopper 372 of the first support 370. In the first operating state, the soap dispenser assembly 1 can be arranged in the through hole opened on the countertop of the washstand through the through hole. Further, the operator can realize the climbing and lowering of the first fastening assembly 360 along the external thread of the first mounting tube 320 by screwing the first mounting tube 320, so as to adjust the distance between the first flange 310 and the first fastening assembly 360 based on the thickness of the countertop of the washstand. When the distance between the first flange 310 and the first fastening assembly 360 is substantially equal to the thickness of the countertop of the washstand, the operator can continue to screw the first mounting tube 320 to make it climb upward. 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 screwing process, due to the effect of gravity, each first wing 362 begins to pivot toward the second wing 3622, so that each first wing 362 is parallel to the wash basin surface. The operator can climb upward by further screwing 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 clamp the wash basin together, thereby providing a different installation method from the prior art using a separate threaded connection component through the integrated structure of the soap dispenser assembly 1.

[0041] Second installation component See also Figure 7 In a second non-limiting embodiment according to the present invention, unlike the aforementioned first mounting assembly 30 which only has a single first mounting tube 320, the second mounting tube assembly 420 of the second mounting assembly 40 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 is axially abutted against the end of the second side tube 422, and the second side tube peripheral wall 4221 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 the first ridge 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, and constructing a more enhanced connection structure, see Fig.10 .

[0042] See also Figure 8 The second side tube 422 may also be partially nested in the first side tube 421 to construct a second mounting tube assembly 420 having substantially double-wall thickness, thereby making the second mounting tube assembly 420 have higher strength relative to the first mounting assembly 30 .

[0043] Specifically, the second side tube upper end 4221 is embedded in the first side tube upper end 4211, and the two together with the engagement ring 430 and the engagement washer 440 form a support portion for the second guide rail 450, as shown in FIG. Figure 7 The second guide rail 450 shown. Furthermore, the first side tube 421 directly constructs a first stopper 460 at a position close to the lower end 4212 of the first side tube. The first stopper 460 extends from the outer periphery of the first side tube 422 substantially in a direction transverse to the central axis of the second side tube 422 to construct a pair of first lateral stops 4611 symmetrically arranged relative to the central axis of the second side tube 422. The pair of first lateral stops 4611 are constructed as an integral structure with the first transverse stopper 4612 at a position close to the lower end 4212 of the first side tube. The first transverse stopper 4612 can also be used to fix and support the second guide rail 450, see Figure 8 .

[0044] In addition, a second stopper 470 is also configured near the lower end 4222 of the second side tube. Similar to the configuration of the first stopper 460, the second stopper 470 is configured in the same manner as a second lateral stopper 4711 and a second transverse stopper 4712, see also Figure 8However, the second side tube upper end 4221 is constructed to have a smaller geometric dimension than the first side tube upper end 4211, and the second side tube lower end 4222 also has a smaller geometric profile than the first side tube lower end 4212. In particular, the second side tube 422 is constructed to have an axial dimension that is significantly smaller than the first side tube 421, and the first side tube 421 is further provided with a groove at its first side tube lower end 4212, so that the second side tube 422 can be embedded in the first side tube 421 from bottom to top along its central axis, and the second stop portion 470 of the second side tube 422 can also be embedded in the first stop portion 460 of the first side tube 421 in a matching manner, see Figure 8 , thereby forming a reinforced second mounting tube assembly 420 .

[0045] The second mounting assembly 40 is also provided with a second fastening assembly 480, see Figure 8-Figure 10 . The second fastening assembly 480 is configured to have at least a second fastening nut 481 and a pair of second wing pieces 482. Each second wing piece 482 is symmetrically arranged 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. In particular, each second wing piece 482 has a third wing portion 4821 and a fourth wing portion 4822, respectively, wherein the fourth wing portion 4822 has a length significantly greater than the third wing portion 4821. In particular, the length of the fourth wing portion 4822 is at least 2 / 3 of the length of the second wing portion 482. Further, the second fastening nut 481 in the second fastening assembly 480 is threadedly connected to the second guide rail 450 (which has an external thread) to form an integrated assembly.

[0046] In view of this, if Fig.10As shown, the second mounting assembly 40 also has a first operating state, that is, the second wing side 4823 of each second wing 482 of the second mounting assembly 40 respectively abuts against the first lateral stopper 4611. In the first operating state, the soap dispenser assembly 1 can be arranged in the through hole opened on the countertop of the washstand through the through hole. Further, the operator can realize the climbing of the second fastening assembly 480 along the external thread of the second guide rail 450 by screwing the second guide rail 450, so as to adjust the distance between the second flange 410 and the second fastening assembly 480 based on the thickness of the countertop of the washstand. When the distance between the second flange 410 and the second fastening assembly 480 is substantially equal to the thickness of the countertop of the washstand, the operator can continue to screw the second guide rail 450. Since the fourth wing 4822 of each second wing 482 in the second fastening assembly 480 has a length significantly greater than the third wing 4821, during the screwing process, due to the effect of 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 further screw the second guide rail 450 to move the second flange 410 of the soap dispenser assembly 1 and each second wing 482 of the second fastening assembly 480 toward the washbasin together and clamp the washbasin, thereby providing a different installation method from the prior art through separate threaded connection components.

[0047] On the other hand, the soap dispenser assembly 1 according to the present invention also has a third operating state suitable for drawing in soap liquid and a fourth operating state suitable for discharging liquid. In the third operating state, the third suction portion 213 of the first suction pipe 210 drives the second thrust piece 240 and the second suction pipe 250, and compresses the elastic component 270 in the axial direction to move linearly in the direction of the second ball valve 280, thereby sucking the soap liquid into the suction sleeve. In the fourth operating state, the elastic component 270 extends in the axial direction and drives the second suction pipe 250, and the second suction pipe 250 pushes the second thrust piece 240 and the third suction portion 213 of the first suction pipe 210 to move linearly away from the second ball valve 280, thereby delivering the soap liquid to the discharge space.

[0048] Furthermore, based on the structure of the aforementioned suction assembly 20 and the sleeve configuration of the first mounting assembly 30 engaged therewith or the sleeve configuration of the second mounting assembly 40 engaged therewith, the soap dispenser assembly 1 of the integrated structure provided by the present invention has higher static and dynamic rigidity than the prior art, and takes into account the stability of the suction process.
