Description

[0001] This application is a divisional application with an application date of "2023.06.28", application number "202310770762.9", and application title "Water Discharge Device". Technical Field

[0002] This invention relates to the field of bathroom equipment technology, and in particular to a water outlet device. Background Technology

[0003] When showering in the bathroom, various devices such as showerheads, waist sprayers, and shoulder sprayers can be used for rinsing. In related technologies, to meet different user needs, the showerhead's spray cover can be rotated to different settings to control different water outlets, thereby adjusting the number of water jets and water pressure. However, once a specific setting is selected, the showerhead's water pressure remains constant, and the water pattern is monotonous, resulting in a generally unsatisfactory user experience. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a water outlet device that can dynamically change the number of water jets and the water pressure, providing a certain massage effect and a variety of water patterns to improve the user experience.

[0005] According to an embodiment of the present invention, a water outlet device includes: a housing having a first water inlet and a water outlet cavity, the bottom wall of the water outlet cavity having a plurality of first through holes; a water passage body connected to the housing, the water passage body having a water passage cavity located within the housing, the side wall of the water passage cavity having a second water inlet; a first water passage for connecting the first water inlet and the second water inlet; an impeller installed in the water passage cavity and capable of rotating under the impact of water flow from the second water inlet; a second water passage for connecting the water passage cavity and the water outlet cavity; and a plurality of water outlets disposed in the water outlet cavity, the plurality of water outlets respectively passing through corresponding first through holes, each water outlet having a central hole. The hole connects the water outlet cavity and the outside of the housing. The inner wall of the central hole is provided with a first jet groove, and the two ends of the first jet groove extend to the two ends of the central hole respectively.

The impeller and the water outlet are connected by a transmission assembly. The transmission assembly includes a first tooth on the impeller and a second tooth on the water outlet. The first tooth meshes with the second teeth of a plurality of water outlets to drive the plurality of water outlets to rotate relative to the protrusion.

[0006] The water outlet device according to embodiments of the present invention has at least the following beneficial effects:

[0007] Water enters through the first inlet and flows through the first water passage to the second inlet, impacting the impeller and causing it to rotate. Because the first tooth of the impeller meshes with the second teeth of multiple outlet nozzles, the impeller can simultaneously drive multiple outlet nozzles to rotate relative to the protruding post. Water enters the water passage chamber through the second inlet and then flows through the second water passage to the outlet chamber. Water in the outlet chamber exits through the first and second jet channels. When the first and second jet channels rotate to the confluence angle, the flow rate and pressure of a single water column are strong; when they rotate to the diversion angle, the number of water columns increases, while the flow rate and pressure of a single water column decrease.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0052] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0053] Reference Figure 1 As shown, a water outlet device 1000 according to an embodiment of the present invention includes a housing 100 and a water outlet 400. The housing 100 is provided with a first water inlet 121, and the water outlet 400 is disposed inside the housing 100 and is used for water outlet. Therefore, water can enter the interior of the housing 100 from the first water inlet 121 and then exit through the water outlet 400. (Refer to...) Figure 2 and Figure 3 As shown, the water outlet 400 can have a spiral, vertical, or inclined water outlet pattern. The water outlet 400 can emit two or four water jets, meaning the number of water jets can vary. Figure 2 and Figure 3 The number shown alternates. Of course, other numbers of water jets are also possible; for example, the number of water jets at the outlet face of a 400 nozzle can alternate between one and two water jets, or between three and five water jets.

[0054] To achieve the function of alternating water column numbers, refer to Figure 4 As shown, in an embodiment of the present invention, the water outlet device 1000 further includes a water passage 200, a first water channel, an impeller 300, a second water channel, and a protrusion 500. The housing 100 includes a main body 110 and a cover 120. The cover 120 is provided with a first water inlet 121. The main body 110 forms a water outlet cavity 111 and an installation space for installing the water passage 200. The cover 120 and the main body 110 are connected, for example, by fasteners such as screws and bolts.

[0055] Reference Figure 5 As shown, the bottom wall of the outlet cavity 111 has a first through hole 112. The water passage 200 is located within the installation space of the main body 110. The water passage 200 has a water passage cavity 210, and the side wall of the water passage cavity 210 has a second inlet 211. A first water passage connects the first inlet 121 and the second inlet 211. For example, the first water passage is a guide cavity 113 formed between the main body 110 and the water passage 200. A second water passage connects the water passage cavity 210 and the outlet cavity 111. For example, the second water passage is a third through hole 220 provided on the bottom wall of the water passage cavity 210. (Refer to...) Figure 6 As shown, the impeller 300 is located in the water passage cavity 210, and the impeller 300 can rotate under the impact of the water flow at the second water inlet 211.

[0056] Reference Figure 7 and Figure 8 As shown, a water outlet 400 is disposed within the water outlet cavity 111. The water outlet 400 includes a connecting post 440, which passes through the first through hole 112. The water outlet 400 has a central hole 410, which is formed inside the connecting post 440 and connects the water outlet cavity 111 to the outside of the housing 100. The inner wall of the central hole 410 is provided with a first jet groove 411, for example, two first jet grooves 411 are spaced apart, and the two ends of the first jet grooves 411 extend to the two ends of the central hole 410, respectively. There may also be one, three, or four first jet grooves 411, etc.

[0057] Reference Figure 5 and Figure 8 As shown, the protruding post 500 is located inside the water outlet cavity 111 and passes through the central hole 410. The outer wall of the protruding post 500 is provided with a second jet groove 510, for example, two second jet grooves 510 are provided at intervals. The two ends of the second jet grooves 510 extend to the two ends of the protruding post 500, respectively. There may also be one, three, or four second jet grooves 510, etc. For ease of explanation, all subsequent embodiments will be described using the example of having two first jet grooves 411 and two second jet grooves 510.

[0058] Reference Figure 5 and Figure 6 As shown, in the water outlet device 1000 of the first embodiment of the present invention, a convex shaft 260 is provided on the bottom wall of the water passage chamber 210, and an impeller 300 is sleeved on the convex shaft 260 and can rotate relative to the convex shaft 260. The convex post 500 and the water passage body 200 are fixedly connected, for example, by means of integral molding, or by means of fasteners. (Refer to...) Figure 9 As shown, the impeller 300 and the water outlet 400 are driven together by a transmission assembly, which includes a gear set 600. The gear set 600 includes a first gear 610 and a second gear 620 coaxially arranged. The impeller 300 has a first tooth 310 that meshes with the first gear 610, and the water outlet 400 has a second tooth 420 that meshes with the second gear 620. When the impeller 300 rotates under the impact of the water flow, the engagement of the first tooth 310 and the first gear 610 drives the gear set 600 to rotate. The gear set 600 then drives the water outlet 400 to rotate through the engagement of the second gear 620 and the second tooth 420.

[0059] Therefore, refer to Figure 10 and Figure 11 As shown, since the first jet channel 411 is located at the outlet 400, and the outlet 400 continuously rotates, it drives the first jet channel 411 to rotate; the second jet channel 510 is located at the protrusion 500, which is fixed to the water passage 200, meaning the protrusion 500 does not rotate relative to the water passage 200, so the second jet channel 510 also does not rotate. Therefore, when the two first jet channels 411 rotate to the angle where they converge with the two second jet channels 510, there are two water columns, and the output flow and pressure of a single water column are relatively strong; when the two first jet channels 411 rotate to the angle where they diverge from the two second jet channels 510, the number of water columns increases to four, and the output flow and pressure of a single water column decrease. Because the outlet 400 rotates, the number of water columns dynamically changes between two and four, and the water column sprayed from the first jet channel 411 can exit in a spiral shape. Since the second jet channel 510 does not rotate, the water jets sprayed from the second jet channel 510 are vertical or inclined. Therefore, the number of water jets, the water volume, and the water pressure of the water outlet device 1000 will dynamically change when water is discharged, without the need for manual adjustment by the user. The dynamically changing water has a certain massage effect when it washes over the human body, providing a good user experience. In addition, some water jets are spiral, while others are vertical or inclined, resulting in a variety of water patterns and a better visual effect.

[0060] Reference Figure 13 , Figure 14 and Figure 15As shown, in the second embodiment of the water outlet device 1000 of the present invention, a protruding post 500 is fixedly connected to a water passage body 200. The first tooth 310 of the impeller 300 passes through the water passage body 200, and the first tooth 310 meshes with the second teeth 420 of a plurality of water outlets 400, thereby driving the plurality of water outlets 400 to rotate. For example, there are three water outlets 400, and three first through holes 112 are correspondingly provided and spaced around the inner wall of the water outlet cavity 111. The connecting post 440 of the three water outlets 400 is correspondingly inserted into the three first through holes 112. There are also three protruding posts 500, which are fixed to the end face of the water passage body 200 facing the main body. The three protruding posts 500 are correspondingly inserted into the three central holes 410.

[0061] Using the water outlet device 1000 of the second embodiment described above, when the two first jet channels 411 rotate to the angle where they converge with the two second jet channels 510, there are two water columns, and the water flow and pressure of a single water column are relatively strong. When the two first jet channels 411 rotate to the angle where they diverge from the two second jet channels 510, the number of water columns increases to four, and the water flow and pressure of a single water column decrease. Because the water outlet 400 rotates, the number of water columns dynamically changes between two and four, and the water column sprayed from the first jet channel 411 can be spiral-shaped. Because the second jet channel 510 does not rotate, the water column sprayed from the second jet channel 510 is vertical or inclined. Therefore, when the water outlet device 1000 outputs water, the number of water jets, the water volume, and the water pressure will change dynamically without the need for manual adjustment by the user. The dynamically changing water has a certain massage effect when it washes over the human body, providing a good user experience. In addition, some water jets are spiral-shaped, while others are vertical or inclined, resulting in a variety of water patterns and a better visual effect.

[0062] It should be noted that the impeller 300 can also directly drive one, two, or four equal numbers of water outlets 400 to rotate, depending on the actual situation.

[0063] In the third embodiment of the water outlet device of the present invention, the impeller 300 and the protruding post 500 are fixedly connected, for example, by integral molding, or by fasteners or other means. The protruding shaft 260 is fixed to the lower end face of the cover 120, and the impeller 300 and the protruding shaft 260 are rotatably connected. The protruding post 500 passes through the third through hole 220, and the water outlet 400 is fixedly connected to the main body 110 or the water passage body 200. Therefore, when the impeller 300 rotates, it drives the protruding post 500 to rotate as well, while the water outlet 400 remains stationary.

[0064] In the third embodiment described above, when the two second jet channels 510 rotate to the angle where they converge with the two first jet channels 411, there are two water columns, with a relatively strong flow rate and pressure per column. When the two second jet channels 510 rotate to the angle where they diverge from the two first jet channels 411, the number of water columns increases to four, and the flow rate and pressure per column decrease. Because the nozzle 400 rotates, the number of water columns dynamically changes between two and four, and the water columns ejected from the second jet channels 510 can exit in a spiral shape. Since the first jet channels 411 do not rotate, the water columns ejected from the first jet channels 411 are vertical or inclined. Therefore, when the water outlet device 1000 outputs water, the number of water jets, the water volume, and the water pressure will change dynamically without the need for manual adjustment by the user. The dynamically changing water has a certain massage effect when it washes over the human body, providing a good user experience. In addition, some water jets are spiral-shaped, while others are vertical or inclined, resulting in a variety of water patterns and a better visual effect.

[0065] Reference Figure 12 As shown, in the fourth embodiment of the water outlet device of the present invention, the impeller 300 and the protruding post 500 are fixedly connected, for example, by integral molding, or by fasteners or other means. The protruding shaft 260 is fixed to the lower end face of the cover 120. The impeller 300 and the protruding shaft 260 are rotatably connected. The protruding post 500 passes through the third through hole 220. The impeller 300 also drives the water outlet 400 to rotate via a gear set 600. For example, the gear set 600 includes a first gear 610 and a second gear 620 coaxially arranged. The impeller 300 has a first tooth 310 meshing with the first gear 610, and the water outlet 400 has a second tooth 420 meshing with the second gear 620. When the impeller 300 rotates under the impact of water flow, the engagement of the first tooth 310 and the first gear 610 drives the gear set 600 to rotate. The gear set 600 then drives the water outlet 400 to rotate via the engagement of the second gear 620 and the second tooth 420.

[0066] In the fourth embodiment described above, the impeller 300 can simultaneously drive the protrusion 500 and the outlet 400 to rotate. Due to the gear set 600 design, by adjusting the gear ratio between the gear set 600 and the first tooth 310 and the second tooth 420, the relationship between the rotational speed of the outlet 400 and the protrusion 500 is adjusted, thereby adjusting the confluence frequency and splitting frequency of the first jet channel 411 and the second jet channel 510, achieving adjustment of the number of water columns and the frequency of water pressure changes. For example, this embodiment of the invention, through reasonable design of the tooth ratio between the first tooth 310, the second tooth 420, the first gear 610, and the second gear 620, allows the rotational speed ratios of the outlet 400 and the protrusion 500 to be different, and allows the protrusion 500 and the outlet 400 to rotate in the same direction or in opposite directions. Both the first jet channel 411 and the second jet channel 510 can produce spiral water outputs. When the two first jet channels 411 rotate to the angle where they converge with the two second jet channels 510, there are two water jets, with strong water flow and pressure per jet. When the two first jet channels 411 rotate to the angle where they diverge from the two second jet channels 510, the number of water jets increases to four, with weaker water flow and pressure per jet. Because the nozzle 400 rotates, the number of water jets dynamically changes between two and four, and the water jets from the first jet channels 411 and the second jet channels 510 exit in a spiral pattern. When the water outlet 1000 dispenses water, the number of water jets, water flow, and water pressure dynamically change, eliminating the need for manual adjustment by the user. The dynamically changing water provides a massage effect when applied to the body, resulting in a good user experience; furthermore, the spiral water jets offer a better visual effect.

[0067] It is understandable that in the first, second, and third embodiments described above, the water pressure affects the rotational speed of the impeller 300, thereby affecting the convergence and divergence frequencies of the first jet channel 411 and the second jet channel 510, and consequently affecting the number of water columns and the frequency of water pressure changes. Therefore, the number of water columns and the frequency of water pressure changes differ under different water pressures; the higher the water pressure, the faster the frequency of change; the lower the water pressure, the slower the frequency of change.

[0068] However, once the gear ratio between the gear set 600 and the first tooth 310 and the second tooth 420 in the fourth embodiment of the present invention is determined, and the impeller 300 and the water outlet 400 rotate in the same direction, the transmission ratio between the protrusion 500 and the water outlet 400 is the same. Therefore, the speed difference between the two remains constant and is not affected by water pressure. Even if the water pressure and flow rate change, the speed difference between the protrusion 500 and the water outlet 400 remains unchanged, making the confluence frequency and split frequency of the first jet channel 411 and the second jet channel 510 constant. Therefore, the frequency of dynamic change in the number of water columns is basically unaffected by the water pressure, effectively avoiding situations where the number of water columns changes too quickly or too slowly due to changes in water pressure, thus reducing the user experience. By rationally designing the transmission ratio between the impeller 300 and the water outlet 400, a suitable frequency for changing the number of water columns can be determined.

[0069] Reference Figure 5 , Figure 9 and Figure 11 As shown in the embodiment of the present invention, when the water outlet device 1000 uses a gear set 600, the gear set 600 further includes a connecting member 630. The connecting member 630 may be cylindrical and is connected between the first gear 610 and the second gear 620. The bottom wall of the water passage body 200 is provided with a second through hole 230, and the connecting member 630 is installed in the second through hole 230. Therefore, the second through hole 230 can restrict the position of the gear set 600, allowing the gear set 600 to rotate in a preset direction.

[0070] Reference Figure 5 and Figure 11 As shown, in a further embodiment of the present invention, the bottom wall of the water passage cavity 210 is provided with a second sleeve 240, and the second through hole 230 is the inner hole of the second sleeve 240. When the gear set 600 is installed in the second through hole 230, the end face of the first gear 610 can abut against the end face of the second sleeve 240 to reduce the contact area between the first gear 610 and the water passage body 200, reduce friction, and make the gear set 600 rotate more smoothly. At the same time, the first sleeve 130 also has the function of restricting the position of the gear set 600, reducing the possibility of the gear set 600 loosening and disengaging from the second through hole 230, and improving the reliability of the water outlet device 1000.

[0071] Reference Figure 5 and Figure 11 As shown in the embodiment of the present invention, the bottom wall of the water outlet cavity 111 is provided with a first sleeve 130, and the first through hole 112 is the inner hole of the first sleeve 130. The connecting post 440 of the water outlet 400 passes through the first through hole 112, and the connecting post 440 and the inner wall of the first through hole 112 are rotatably engaged. The first sleeve 130 serves to limit the position of the connecting post 440, so that the water outlet 400 can rotate in a preset direction when rotating, reducing the possibility of the water outlet 400 disengaging from the first through hole 112.

[0072] Reference Figure 5 As shown, in an embodiment of the present invention, the water-passing body 200 further includes a boss 250, which surrounds at least a portion of the sidewall of the water-passing cavity 210. (Refer to...) Figure 11 As shown, the impeller 300 and the boss 250 abut against each other, which can reduce the contact area between the impeller 300 and the water passage body 200, thereby reducing friction and improving the service life and smoothness of the impeller 300.

[0073] Reference Figure 9 As shown in a further embodiment of the present invention, the impeller 300 includes a reinforcing edge 330, a base 340, and a plurality of blades 320. One end of each blade 320 is connected to the base 340 and arranged radially, while the other end of each blade 320 is connected to the reinforcing edge 330. The blades 320 facilitate water flow impact to drive the impeller 300 to rotate. The reinforcing edge 330 is used to improve the stability of the connection between the blades 320 and the base 340, thereby improving the overall strength of the impeller 300. Furthermore, the reinforcing edge 330 can abut against the boss 250 to reduce the contact area between the impeller 300 and the water-passing body 200.

[0074] Reference Figure 8 As shown, in an embodiment of the present invention, the first jet channel 411 is a spiral structure extending along the axial direction of the central hole 410, so that the first jet channel 411 can tilt to discharge water, and when the water outlet 400 rotates, it facilitates the water to be in a spiral shape. The second jet channel 510 is a spiral structure extending along the axial direction of the protrusion 500, and the effect is similar to that when the first jet channel 411 is spirally arranged, so it will not be described again here. In a further embodiment of the present invention, both the first jet channel 411 and the second jet channel 510 are spirally arranged and rotate in the same direction. When the first jet channel 411 and the second jet channel 510 rotate to the confluence angle, it is beneficial for water to exit from the first jet channel 411 and the second jet channel 510, improving the smoothness of water discharge.

[0075] In other embodiments of the present invention, the first jet groove 411 may be spiral or straight, extending along the axis of the central hole 410; the second jet groove 510 may also be straight, extending along the axis of the protrusion 500. The cross-sections of the first jet groove 411 and the second jet groove 510 may be circular, triangular, polygonal, elliptical, etc., and a suitable solution may be selected according to the actual situation.

[0076] Reference Figure 9 and Figure 11As shown in the embodiment of the present invention, the end of the water outlet 400 facing the third through hole 220 is provided with a groove 430. On the projection plane perpendicular to the central hole 410, the projection of the third through hole 220 is located within the projection of the groove 430, and the first jet channel 411 and the second jet channel 510 are both connected to the groove 430. Therefore, water in the water passage cavity 210 can fall directly into the groove 430 through the third through hole 220, reducing water pressure loss and facilitating water output from the first jet channel 411 and the second jet channel 510. Of course, in another embodiment, the projection of the third through hole 220 can also be located outside the groove 430, as long as water can enter the water outlet cavity 111 when water enters the third through hole 220.

[0077] Reference Figure 16 and Figure 17 As shown, in an embodiment of the present invention, the flow cross-sectional area of ​​the second inlet 211 gradually decreases along the direction close to the impeller 300. It is understood that as the flow cross-sectional area gradually decreases, the water flow velocity increases, thereby driving the impeller 300 to rotate more rapidly, allowing the number of water jets to alternate.

[0078] Reference Figure 17 As shown, in this embodiment of the invention, the extension direction of the second inlet 211 does not intersect with the rotation axis of the impeller 300. This facilitates the impeller 300 to rotate along its axis when water enters through the second inlet 211, and the impeller 300 then drives the protrusion 500 or the outlet 400 to rotate, thereby alternating the number of water jets and the water flow force, improving the user experience.

[0079] Reference Figure 6 and Figure 9 As shown, in an embodiment of the present invention, two impellers 300 are provided in a water passage chamber 210, and two water outlets 400 are provided in a water outlet chamber 111. At least two second water inlets 211 are provided on the sidewall of the water passage chamber 210 to simultaneously drive the two impellers 300 to rotate. The two impellers 300 then drive the two water outlets 400 to rotate via a gear set 600. This design improves the smoothness of the gear set 600's rotation, and by using two impellers 300, the gear set 600 can be driven to rotate more effectively, reducing the water pressure required to drive the gear set 600. In another embodiment, one, three, or four impellers 300 can also be provided in the water passage chamber 210; and one, three, or four water outlets 400, etc., can be provided in the water outlet chamber 111. The appropriate number is selected based on the actual situation.

[0080] Reference Figure 4As shown in the embodiment of the present invention, the water passage 200 is provided with multiple water passage chambers 210 at intervals, and the main body 110 is provided with multiple water outlet chambers 111 at intervals, the number of water outlet chambers 111 being the same as the number of water passage chambers 210. Each water passage chamber 210 is provided with an impeller 300, and each water outlet chamber 111 is provided with a water outlet 400 and a protrusion 500. When the first water path adopts the form of a guide chamber 113, one guide chamber 113 can supply water to multiple water passage chambers 210. The water passage chambers 210, water outlet chambers 111, impellers 300, protrusions 500, and water outlets 400 can constitute a module unit. During the design stage, by increasing or decreasing the number of module units, the water outlet device 1000 can obtain different sizes of water outlet areas. For example, the water outlet device 1000 can be a waist spray, shoulder spray, or top spray, etc., and the required water outlet area is designed according to the functional requirements of the waist spray, shoulder spray, and top spray. In another embodiment of the present invention, the water outlet device 1000 itself can also be a module unit. By reasonably designing the number of water outlet devices 1000 and the connection structure between multiple water outlet devices 1000, different application scenarios can be met.

[0081] In other embodiments of the present invention, the first water path can be implemented not only through the water passage cavity 210, but also through an independent water passage channel, such as a water passage hole or water passage groove, or through an internal or external pipe, such as a flexible hose; thereby connecting the first water inlet 121 and the second water inlet 211. The second water path can be implemented not only through the third through hole 220, but also through an independent water passage channel, such as a water passage hole or water passage groove, or through an internal or external pipe, such as a flexible hose; thereby connecting the water passage cavity 210 and the water outlet cavity 111. The appropriate solution is selected based on the actual situation.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
