Description

Technical Field

[0001] The present invention relates to the technical field of water outlet devices, and in particular to a water outlet device and a shower head. Background Art

[0002] In order to provide more diverse water discharge patterns, such as forming massage pulse water splashes, some types of existing shower heads are equipped with impellers inside. After the water flow hits the impeller, it drives the impeller to rotate, thereby making the water discharge patterns more diverse. However, the rotation of the impeller is only affected by the flow rate of the water flow. When the water flow rate is too fast, the rotation speed of the impeller will also increase accordingly, resulting in adverse consequences such as weakening of the massage effect of the pulse water splash. Therefore, it is necessary to control the rotation speed of the impeller. The means of decelerating the impeller in the prior art is mainly to decelerate the impeller step by step through planetary gears. This solution makes the structure of the internal module accessories of the shower head extremely complex, and there are problems such as difficult assembly, high manufacturing cost and difficult to guarantee service life. Summary of the invention

[0010] A sixth technical solution based on the fourth technical solution: a bottom wall of the water passage cavity is provided with a boss extending into the water passage cavity; the second water outlet hole passes through the boss; the second inclined water channel is opened on the boss and communicated with the second water outlet hole.

[0013] A ninth technical solution based on the seventh or eighth technical solution: a first position on the rotating member is provided with a plurality of blades extending radially thereof along the circumferential direction; the blades are used to receive the impact of the water flow guided by the first inclined water channel.

[0014] In addition, the present invention also provides a tenth technical solution: a shower head, comprising a water outlet device as described in any one of the first to ninth technical solutions above.

[0015] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0016] The first technical scheme provides a water outlet device, which is provided with a first oblique water channel and a second oblique water channel. The first oblique water channel can guide the water flow to impact the first position on the rotating member and push the rotating member to rotate along the first direction. The second oblique water channel can guide the water flow to impact the second position on the rotating member and apply a rotational resistance opposite to the first direction to the rotating frame, thereby weakening the driving force applied to the rotating member to rotate it along the first direction, and also reducing the rotation speed of the rotating member; this technical scheme uses two streams of water to impact the rotating member at the same time and apply driving forces in opposite directions to the rotating member, so that the rotating member can have a lower rotation speed than the ordinary situation where only one stream of water applies force. This deceleration scheme has a simple structure and does not require the addition of extra components. The deceleration degree can be adjusted by adjusting the relevant parameters of the first oblique water channel and the second oblique water channel, thereby solving the problems of complex structure, high cost and difficult maintenance of the existing water outlet device with deceleration function.

[0017] The second technical solution stipulates that a water inlet channel for water inlet and a water flow chamber for accommodating a rotating part are provided on the base of the water outlet device, and a first water outlet channel is also provided in the rotating part, and cooperates with the base to form a second water outlet channel. Water flows through the water inlet channel into the first inclined water channel and then into the water flow chamber, and at the same time impacts the first position of the rotating part to rotate the rotating part along the first direction. At this time, part of the water in the water flow chamber flows out from the first water outlet channel, and the other part of the water flows along the second inclined water channel to impact the second position of the rotating part and exert rotational resistance on the rotating part, and then flows out from the second water outlet channel.

[0018] The third technical solution stipulates that the base of the water outlet device is provided with a water inlet channel for water inlet and a water flow chamber for accommodating the rotating part, and a first water outlet hole for water outlet is also provided. The rotating part is provided with a water baffle plate, and cooperates with the base to form a second water outlet channel. The water flows through the water inlet channel into the first inclined water channel and then into the water flow chamber, and at the same time impacts the rotating part to make the rotating part rotate along the first direction. At this time, part of the water flow in the water flow chamber will flow out from the first water outlet hole, and the other part of the water flows from the water flow chamber along the second inclined water channel to impact the rotating part and apply rotational resistance to the rotating part, and then flows out from the second water outlet channel. At the same time, when the rotating part rotates, the water baffle plate will intermittently block the first water outlet hole, thereby forming intermittent massage water splashes.

[0019] The fourth technical scheme provides two ways of forming a second water outlet channel on the basis of the second technical scheme and the third technical scheme. One of them is to set a second water outlet hole on the base, and the rotating member extends into the second water outlet hole and cooperates with the second water outlet hole to form a gap, and the gap is the second water outlet channel. The other way is to set a second water outlet hole on the base, and set a water groove on the rotating member. The groove wall of the water groove and the hole wall of the second water outlet hole are combined to form the second water outlet channel; at the same time, in the above two schemes, a water groove is set on the rotating member, and the water groove can be used to receive the impact of water flow, so that the water flow guided by the second inclined water channel can exert rotational resistance on the rotating member.

[0020] The fifth technical solution stipulates that protrusions are provided on the rotating member, and the intervals between the protrusions form the above-mentioned water flow grooves.

[0021] The sixth technical solution defines that a boss is provided on the bottom wall of the water passage chamber, and the boss is used to set the second inclined water channel.

[0022] The seventh technical solution stipulates that a flange is also provided on the rotating part, and the flange can overlap and cooperate with the boss, so that the rotating part can be installed in the water flow chamber, avoiding contact between the impeller part of the rotating part and the bottom wall of the water flow chamber, reducing the friction between the rotating part and the bottom wall of the water flow chamber, and at the same time slightly lifting the rotating part so that a gap can be formed between the rotating part and the second water outlet.

[0023] The eighth technical scheme defines that a water inlet channel and a water flow chamber for accommodating a rotating part are provided on the base of the water outlet device, and a first water outlet hole is also provided. A water baffle and a return water chamber are provided on the rotating part. The water flows through the water inlet channel into the first inclined water channel and then into the water flow chamber, and at the same time impacts the rotating part to cause the rotating part to rotate in the first direction. At this time, part of the water flow in the water flow chamber will flow out from the first water outlet hole, and the other part of the water flow will impact the side wall of the water flow hole of the rotating part along the second inclined water channel and exert rotational resistance on the rotating part, and then enter the return water chamber through the water flow hole, the water flow chamber and then flow out from the first water outlet hole. At the same time, when the rotating part rotates, the water baffle will intermittently block the first water outlet, thereby forming intermittent massage water splashes.

[0024] The ninth technical solution stipulates that blades are provided on the rotating member, and the first inclined water channel guides the water flow to impact the blades to make the rotating member rotate along the first direction.

[0025] The tenth technical solution provides a shower head, which includes the above-mentioned water outlet device and has the advantages of simple water outlet structure and various water outlet styles. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention provides the following embodiments to explain in detail the water outlet device and shower head provided by the present invention.

[0046] Embodiment 1

[0047] See also Figure 1 , Figure 1 The structure explosion diagram of a water outlet device provided in this embodiment is shown, and the water outlet device mainly includes a water receiving member 21, an upper cover 22, a base 23, a rotating member 10, and a first sealing ring 31, a second sealing ring 32 and a third sealing ring 33. The position where the water receiving member 21 is located is the upper side, and the position where the base 23 is located is the lower side.

[0048] Reference Figure 4 and Figure 5 In this embodiment, the main part of the water receiving member 21 is a plate-like member, and the middle position of the lower side surface of the plate-like member is inwardly recessed to form a groove-like structure with a circular cross section. A through hole is provided at the center of the groove-like structure, and the through hole forms a water inlet hole 212. Corresponding to the position of the water inlet hole 212, a screw connection column is provided on the upper side surface of the plate-like member. The screw connection column is provided with an external thread, and its interior is hollow and connected to the through hole. The water receiving member 21 can be fixedly connected to the external water inlet pipe through the screw connection column, so as to introduce water into the water outlet device.

[0049] Reference Figure 4 and Figure 5 In this embodiment, the main part of the upper cover 22 is also a plate-like component, and a first columnar structure with a circular cross section and a hollow interior is formed on the lower side surface of the plate-like component. An internal thread is provided on the inner wall of the first columnar structure, and an upper cover water hole 221 is provided at the bottom wall (upper end of the first columnar structure) of the first columnar structure; another second columnar structure with a circular cross section and a hollow interior is formed on the upper side surface of the plate-like component, and the outer diameter of the second columnar structure is equal to the inner diameter of the side wall of the groove structure of the water receiving member 21 located below it, and a first sealing ring 31 is provided on the outer wall of the second columnar structure. The second columnar structure of the upper cover 22 can be inserted into the groove structure of the water receiving member 21, and cooperate with it to form a water inlet chamber 211. The first sealing ring 31 can prevent the water inlet chamber 211 from leaking. The upper cover 22 can be stably fixed to the water receiving member 21 by bonding, clamping or welding.

[0050] Reference Figure 2 , Figure 4 and Figure 5The base 23 is a cylindrical member having a bottom wall, a chamber formed inside, and an outer diameter thereof matching the inner diameter of the first columnar structure formed on the lower surface of the upper cover 22. At the same time, an outer thread matching the upper cover 22 is also provided on the outer wall thereof, so that the base 23 can be screwed to the upper cover 22 and cooperate with it to form the base of the water outlet device, and the upper opening of the base 23 is blocked by the lower surface of the upper cover 22, thereby forming a closed chamber, which is the water passage chamber 235. A circle of protruding ribs 238 are provided along the circumferential direction at a position near the upper opening of the outer wall of the base 23. When the base 23 is fixedly connected to the upper cover 22, the inner wall of the first columnar structure cooperates with the outer wall of the base 23 to form a water inlet groove 239, and the outlet of the water hole 221 of the upper cover just corresponds to the water inlet groove 239. The water inlet groove 239, the water hole 221 on the upper cover, and the water inlet cavity 211 together constitute the water inlet channel of the base. A second sealing ring 32 and a third sealing ring 33 are respectively installed on the upper end surface of the base 23 and the middle position of its outer wall, and these two sealing rings can prevent water in the water inlet groove 239 from leaking.

[0051] The side wall of the base 23 is also provided with a plurality of oblique water holes 236 penetrating the side wall along the circumferential direction. The oblique water holes 236 form a first oblique water channel of the base, and the inlet thereof corresponds to the position of the water inlet groove on the outer wall of the base 23. Figure 4 The inclined direction of the inclined water hole 236 allows water to flow from the outlet of the inclined water hole 236 into the water passage chamber 235 in a clockwise direction.

[0052] A second water outlet hole 234 penetrating the bottom wall of the base 23 is provided at the center of the bottom wall of the base 23, and a circle of bosses 232 are provided on the bottom wall near the second water outlet hole 234. The bosses 232 are annular structures protruding from the bottom wall, and surround the opening of the second water outlet hole 234 toward the water cavity 235, that is, the second water outlet hole 234 passes through the bosses 232; at the same time, the inner wall of the boss 232 is connected to the inner wall of the second water outlet hole 234. An inclined water groove 233 is provided on the boss 232, and the inclined water groove 233 forms a second inclined water channel on the base, and the extension direction of the inclined water groove 233 is perpendicular to the protruding direction of the boss 232, and passes through the inner and outer walls of the boss 232, and at the same time, an opening is formed on the upper end face of the boss 232. Figure 5 The inclined water trough 233 connects the water cavity 235 and the second water outlet 234 , and its inclined direction allows water to flow from the outlet of the inclined water trough 233 to the second water outlet 234 in a counterclockwise direction.

[0053] In addition, a protruding rib 231 higher than the upper end surface of the boss 232 is formed on the outer wall of the boss 232 toward the direction of the water passage chamber 235, and the inclined water groove 233 also penetrates the protruding rib 231. The protruding rib 231 cooperates with the upper end surface of the boss 232 to form a step-like structure, and cooperates with the second water outlet 234 to form a step hole structure.

[0054] Reference Figure 3 The main body of the rotating member 10 is a cylindrical member. A plurality of blades 11 extending in the radial direction of the rotating member 10 are arranged circumferentially at the upper position of the rotating member 10. The position of the blades 11 is the first position on the rotating member 10. When the rotating member 10 is installed in the water passage chamber 235, the extending direction of the inclined water hole 236 is perpendicular to the axial direction of the rotating member 10, and the water flow guided by the inclined water hole 236 impacts the blades 11, thereby driving the rotating member 10 to rotate in the first direction. In this embodiment, the first direction is clockwise.

[0055] A flange 12 extending in the circumferential direction is provided at the middle of the rotating member 10 and protrudes radially outward. A rotating surface 14 is formed on the outer wall surface of the rotating member 10 below the flange 12, and the rotating surface 14 is the second position on the rotating member 10. A plurality of water grooves 13 are arranged in the circumferential direction on the rotating surface 14, and the water grooves 13 extend in the axial direction of the rotating member 10, and both ends of the water grooves 13 are closed.

[0056] A first water outlet channel 16 is also provided in the rotating member 10 along its axial direction. The upper end of the first water outlet channel 16 is connected to the upper end surface of the rotating member 10. When the rotating member 10 is installed in the water passage chamber 235, the first water outlet channel 16 can be connected to the water passage chamber 235. The lower end of the first water outlet channel 16 forms a first water outlet channel outlet 15, which can discharge the water in the water passage chamber 235 to the outside of the water outlet device. At the same time, in this embodiment, the first water outlet channel outlet 15 is spindle-shaped, which can form a blade-shaped water outlet.

[0057] The outer diameter of the rotating surface 14 of the rotating member 10 is slightly smaller than the inner diameter of the second water outlet hole 234, so that the lower end of the rotating member 10 can be inserted into the second water outlet hole 234, and the outer diameter of the flange 12 is roughly equal to the inner diameter of the protruding rib 231, so that the rotating member 10 can overlap the upper end surface of the boss 232 and be limited by the protruding rib 231 to prevent the rotating member 10 from shifting. At the same time, a water gap can be formed between the rotating surface 14 and the inner wall of the second water outlet hole 234, and the water gap forms a second water outlet channel; when the flange 12 overlaps the boss 232, the flange 12 can also cover the upward opening of the inclined water groove 233 on the boss 232, so that the water flow in the water cavity 235 can only enter the inclined water groove 233 from the outside of the protruding rib 231.

[0058] When the rotating member 10 is overlapped onto the boss 232, the position of the water channel 13 corresponds exactly to the outlet of the inclined water channel 233, and the extension direction of the inclined water channel 233 is also perpendicular to the axial direction of the rotating member 10. The water flow guided by the inclined water channel 233 will impact the side wall of the water channel 13 and exert a driving force on the rotating member 10. In this embodiment, the driving force applied by the water flow guided by the inclined water groove 233 is the rotational resistance of the rotating member 10, and its force application direction is opposite to the direction of the driving force applied by the water flow guided by the inclined water hole 236 to the rotating member 10. However, since the water flow chamber 235 is directly connected to the first water outlet channel 16, and the water flow area of ​​the first water outlet channel outlet 15 is much larger than the water flow area of ​​the second water outlet channel, the driving force applied by the water flow guided by the inclined water hole 236 is also greater than the resistance applied by the water flow guided by the inclined water groove 233. Therefore, the rotating member 10 will still rotate along the first direction, but because it is also subject to rotational resistance, its rotation speed will be reduced, thereby achieving the purpose of slowing down the rotating member 10. At this time, the water shape of the blade water formed by the rotation of the rotating member 10 will be softer.

[0059] In addition, although the inclined water trough 233 and the inclined water hole 236 are arranged to extend in directions perpendicular to the axial direction of the rotating part 10 in the present embodiment, their extension directions can also be arranged to be inclined to the axial direction of the rotating part 10. As long as the water flow guided by the two can exert a driving force on the rotating part 10 to make it rotate, the vertical direction is the preferred embodiment.

[0060] Reference Figure 6 The water outflow from the second water outlet channel will form a water curtain outside the blade-shaped water outlet formed on the outlet 15 of the first water outlet channel, and the water curtain can prevent the blade water from splashing.

[0061] During assembly, the rotating member 10 is first installed on the base 23, and then the base 23 is screwed to the upper cover 22, and then the upper cover 22 is fixedly connected to the water receiving member 21, and finally the following is obtained: Figure 7 The water outlet device shown.

[0062] Embodiment 2

[0063] The difference between the second embodiment and the first embodiment lies in that the structures of the base 23 and the rotating member 10 are different.

[0064] Reference Figure 8In this embodiment, compared with the base 23 in the first embodiment, the difference lies in that: the bottom wall of the base 23 is provided with a second water outlet hole 234 which is the same as that in the first embodiment, and a boss 232 is provided at a position corresponding to the second water outlet hole 234, and the boss 232 is provided with an inclined water groove 233 which is the same as that in the first embodiment; at the same time, a plurality of first water outlet holes 237 are provided along the circumferential direction on the bottom wall of the base 23, and the first water outlet holes 237 are located between the boss 232 and the side wall of the base 23.

[0065] Reference Fig. 9 In this embodiment, compared with the rotating member 10 in the first embodiment, the difference is that three water baffles 17 are also provided on the outer edge of the flange 12 of the rotating member 10, and the lower surface of the water baffle 17 is lower than the lower surface of the flange 12, so a lap groove 171 is formed between the rotating surface 14 and the water baffle 17, and the width of the lap groove 171 is equal to the width of the boss 232. When the rotating member 10 is inserted into the second water outlet hole 234, the lap groove 171 will be plugged and matched with the boss 232 to prevent the rotating member 10 from shifting and make the flange 12 overlap the boss 232. At the same time, the bottom end of the first water outlet channel 16 on the rotating member 10 is closed, and the water can only flow out from the first water outlet hole 237 and the gap between the rotating member 10 and the second water outlet hole 234.

[0066] When the rotating member 10 rotates, the water baffle 17 will intermittently block the first water outlet 237, so that the water outlet device forms intermittent massage water splashes.

[0067] Embodiment 3

[0068] The difference between the third embodiment and the second embodiment is that the structures of the base 23 and the rotating member 10 are different.

[0069] Reference Fig.10 In this embodiment, compared with the base 23 in the second embodiment, the difference is that the second water outlet hole 234 on the bottom wall of the base 23 is closed toward the opening below to form a sink hole.

[0070] Reference Fig.11 In this embodiment, compared with the rotating member 10 in the second embodiment, the difference is that the rotating member 10 forms a water return chamber 18 corresponding to the structure of the original first water outlet channel 16, and when the rotating member 10 is installed in the water passage chamber 235, the upper end of the water return chamber 18 is connected with the water passage chamber 235. A water return chamber water passage hole 181 is provided on the rotating surface 14 of the rotating member 10. The structure of the water return chamber water passage hole 181 is similar to that of the water passage groove 13, but it is in a through state at a position corresponding to the bottom wall of the water passage groove 13, so that the water return chamber water passage hole 181 is connected with the water return chamber 18.

[0071] When water flows into the water cavity 235 from the inclined water hole 236, it will first impact the blade 11 and push the rotating part 10 to rotate in the first direction. Then, most of the water will flow out from the first water outlet hole 237, and a small part of the water will pass through the inclined water groove 233 and impact the side wall of the return water cavity water hole 181, exerting rotational resistance on the rotating part 10. Then, the water will enter the return water cavity 18 from the return water cavity water hole 181, and then flow out through the first water outlet hole 237.

[0072] Embodiment 4

[0073] The difference between the fourth embodiment and the first embodiment lies in that the structure forming the second water outlet channel is different.

[0074] In this embodiment, the water groove 13 extends along the axial direction of the rotating member 10 to the bottom end of the rotating member 10, and no water gap is formed between the rotating surface 14 of the rotating member 10 and the inner wall of the second water outlet hole 234. The rotating member 10 and the second water outlet hole 234 are tightly matched, but the rotating member 10 can still rotate relative to the base 23. At this time, the water groove 13 itself cooperates with the inner wall of the second water outlet hole 234 to form a second water outlet channel. When the water flows through the inclined water groove 233 and hits the side wall of the water groove 13, the water flows along the water groove 13 to the bottom end of the rotating member 10 and is discharged outside the water outlet device.

[0075] Embodiment 5

[0076] The difference between the fifth embodiment and the first, second and fourth embodiments is that the water channel 13 is formed in a different manner.

[0077] As described in the first, second and fourth embodiments, the water groove 13 in the above embodiments is formed by directly recessing the rotating surface 14. In this embodiment, a plurality of protrusions are provided on the rotating surface 14, and the intervals between the protrusions form the above water groove 13. Furthermore, the above protrusions extend along the axial direction of the rotating member 10, so that the formed water groove 13 also extends along the axial direction. The position where the water flow guided by the inclined water groove 233 impacts is the side wall of the protrusion.

[0078] Of course, the water channel 13 formed by the protrusions can be arranged to extend to the bottom end of the rotating member 10, or be closed at both ends according to specific circumstances.

[0079] It should be noted that, for any of the above-mentioned embodiments, by adjusting the water flow area of ​​the second water outlet channel, the width of the water channel 13, and the width of the inclined water channel 233, the rotational resistance formed after the water flow guided by the second inclined water channel impacts the rotating member 10 can be adjusted, thereby adjusting the deceleration degree of the rotating member 10.

[0080] In addition, the present invention further provides a shower head, which includes any water outlet device in the above-mentioned embodiments 1 to 5.

[0081] The present invention provides a water outlet device and a shower head, in which two water flows simultaneously impact a rotating member 10 and apply a driving force in opposite directions to the rotating member 10, so that the rotating member can have a lower rotation speed than the ordinary case where only one water flow applies force. This deceleration scheme has a simple structure, does not require the addition of redundant components, and has excellent effects. The degree of deceleration can be adjusted by adjusting the relevant parameters of the first oblique water channel and the second oblique water channel, thereby solving the problems of the existing water outlet device with deceleration function having a complex structure, high cost, and difficult maintenance.

[0082] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
