Description

Technical Field

[0001] The utility model relates to the technical field of shower heads, in particular to an impeller assembly for a massage shower head and a massage shower head. Background Art

[0002] As people's living standards improve, they are pursuing a more comfortable experience while improving cleaning effects. Massage water refers to water with a massage effect. By changing the shape, force, and direction of the water, the water can produce a massage effect when it contacts the skin. The massage function of flower wine on the market generally achieves a pulse effect by intermittent water discharge through the rotation of the impeller. The impeller's speed changes with the water pressure, resulting in a less obvious massage effect when the water pressure is low. When the water pressure is high, the pulse frequency is too fast and it can cause a stinging sensation. When the water pressure remains unchanged, the impeller speed is fixed, and the massage effect is monotonous.

[0003] Among the existing patents, the Chinese patent document with application number 202120512347.X discloses a massage water outlet mechanism and a massage shower head. The massage water outlet mechanism includes a water diverter and an end cover. The water diverter is provided with an oblique water inlet channel. The end cover is provided with a first water outlet channel on the side away from the water diverter. The impeller, the rectifier and the gear assembly are arranged in sequence along the direction of water flow in the cavity formed by the connection between the water diverter and the end cover. After the water flows into the water inlet channel, it drives the impeller to rotate, thereby causing the gear assembly to rotate. A part of the water flows through the rectifier and flows out through the second water outlet channel in the center of the gear assembly, and the other part of the water flows out through the gap between the first water outlet channel and the second water outlet channel. This patent document only has one set of water inlet channels with the same inclination angle. When the water pressure and water flow remain unchanged, the speed of the impeller is fixed, and the massage effect is single.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide an impeller assembly for a massage shower head and a massage shower head.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The driven gear is engaged with the driving gear. The impeller and the multiple massage water outlet heads are all located in the working chamber. The water jet disc is inclined to be provided with multiple groups of hole groups connected to the working chamber. The inclination angles of the multiple groups of hole groups are different. Each group of hole groups includes multiple water inlet holes. The water inlet holes of the multiple groups of hole groups are arranged in a ring array around the central axis of the impeller. The water inlet holes of the multiple groups of hole groups are arranged at intervals. The blades of the impeller are rotated outside the end of the inclined water outlet hole away from the massage water outlet shell.

[0008] Furthermore, a rotating shaft is provided at the center of the impeller, and both ends of the rotating shaft are rotatably connected to the massage water outlet shell and the water jet disc respectively.

[0009] Furthermore, the number of hole groups is two.

[0010] Furthermore, an outer ring and an inner ring are provided on a side of the water jetting disc away from the massage water outlet shell, one group of hole groups is located between the outer ring and the inner ring, and the other group of hole groups is located inside the inner ring.

[0011] Furthermore, the massage water outlet shell and the water spraying disc are connected via a fool-proof structure.

[0012] Furthermore, the fool-proof structure includes a convex column and a concave hole that is concavely matched with the convex column. The convex column is arranged on the massage water outlet shell and / or the water spraying dish, and correspondingly, the concave hole is arranged on the water spraying dish and / or the massage water outlet shell.

[0015] The present invention has the following beneficial effects: In actual use, high-pressure water is supplied to the multiple water inlet holes of one of the hole groups. The water inlet holes spray water obliquely into the working chamber, driving the impeller in the working chamber to rotate. The driving gear on the rotating impeller engages with the driven gears of the multiple massage water outlets, driving the multiple massage water outlets to rotate. Water flows through the oblique water outlet holes to eject water jets. As the massage water outlets rotate, the water jets swing and spray onto the user, providing a massage. Because the multiple hole groups have different inclination angles, supplying high-pressure water to hole groups with different inclination angles, while maintaining constant water flow and water pressure, results in different impeller rotation speeds, thereby changing the rotation speed of the massage water outlets and, in turn, varying the massage effect on the user. Specifically, among the multiple hole groups, if the inclination angle of the water inlet holes is relatively small, the rotation speed of the impeller and massage water outlets is relatively fast, achieving a fast massage effect; if the inclination angle of the water inlet holes is relatively large, the rotation speed of the impeller and massage water outlets is relatively slow, achieving a slow massage effect. The utility model can achieve massage effects with different massage speeds by arranging multiple groups of holes with different inclination angles on the water-spraying dish, thereby meeting the different massage speed requirements of users.

[0023] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0024] like Figures 1 to 5 As shown, the utility model provides an impeller assembly for a massage shower, which includes a massage water outlet shell 1, an impeller 2, a water jet dish 3 and a plurality of massage water outlet heads 4. The water jet dish 3 is installed on the inner side of the massage water outlet shell 1, and a working chamber 5 is formed between the water jet dish 3 and the massage water outlet shell 1. The inner side of the massage water outlet shell 1 is rotatably connected to the impeller 2. A driving gear 6 is provided on the side of the impeller 2 close to the massage water outlet shell 1. The massage water outlet shell 1 is provided with a plurality of water outlet channels 7. The plurality of water outlet channels 7 are arranged in a ring array around the central axis of the impeller 2. The plurality of massage water outlet heads 4 are respectively arranged in a one-to-one correspondence with the plurality of water outlet channels 7. The massage water outlet heads 4 are rotatably arranged in the water outlet channels 7. The massage water outlet heads 4 are provided with inclined outlets. Water hole 8, the inclined water outlet hole 8 is exposed in the water outlet channel 7, the massage water head 4 is located between the massage water outlet shell 1 and the impeller 2, and the massage water outlet head 4 is provided with a driven gear 9 at one end close to the impeller 2. The driven gear 9 is in transmission engagement with the driving gear 6. The impeller 2 and the multiple massage water heads 4 are all located in the working chamber 5. The water-jetting disc 3 is inclined to be provided with multiple groups of hole groups 10 communicating with the working chamber 5. The inclination angles of the multiple groups of hole groups 10 are different. Each group of hole groups 10 includes multiple water inlet holes. The water inlet holes of the multiple groups of hole groups 10 are arranged in a ring array around the central axis of the impeller 2. The water inlet holes of the multiple groups of hole groups 10 are arranged at intervals. The blades of the impeller 2 are rotated outside the inclined water outlet hole 8 away from the end of the massage water outlet shell 1.

[0025] In actual use, high-pressure water is supplied to the multiple water inlets of one of the hole groups 10. The water inlets will obliquely spray the water into the working chamber 5, driving the impeller 2 in the working chamber 5 to rotate. The driving gear 6 on the rotating impeller 2 is meshed with the driven gear 9 of the multiple massage water outlets 4 to drive the multiple massage water outlets 4 to rotate. The water will then be ejected through the inclined water outlets 8 as a water column. As the massage water outlets 4 rotate, the water column will swing and spray onto the user to massage the user. Because the multiple hole groups 10 have different inclination angles, if the water flow rate and water pressure remain unchanged, supplying high-pressure water to the hole groups 10 with different inclination angles will cause the impeller 2 to rotate at different speeds, thereby changing the speed of the massage water outlets 4 and thus providing different massage effects on the user. Specifically, in the multiple groups of hole groups 10, if the inclination angle of the water inlet holes is relatively small, the rotation speed of the impeller 2 and the massage water outlet head 4 is relatively fast, thereby achieving a fast massage effect; if the inclination angle of the water inlet holes is relatively large, the rotation speed of the impeller 2 and the massage water outlet head 4 is relatively slow, thereby achieving a slow massage effect. The present utility model can achieve massage effects of different massage speeds by providing multiple groups of hole groups 10 with different inclination angles on the water jet disc 3, thereby meeting the different massage speed requirements of users.

[0026] In this embodiment, a rotating shaft 11 is provided at the center of the impeller 2, and both ends of the rotating shaft 11 are respectively rotatably connected to the massage water outlet housing 1 and the water jet disc 3. This structural design improves the rotation stability of the impeller 2.

[0027] In this embodiment, there are two groups of hole groups 10. This structural design allows one group of hole groups 10 to be in a fast massage mode and the other group of hole groups 10 to be in a slow massage mode.

[0028] In this embodiment, an outer ring 12 and an inner ring 13 are provided on the side of the water jet disc 3 away from the massage water outlet housing 1. The inner ring 13 is generally shaped like a clover. One group of hole groups 10 is located between the outer ring 12 and the inner ring 13, and the other group of hole groups 10 is located within the inner ring 13. The arrangement of the outer ring 12 and the inner ring 13 forms two independent water chambers. The two groups of hole groups 10 are distributed in different independent water chambers. Different speeds of the impeller 2 can be achieved by filling different independent water chambers with water.

[0029] In this embodiment, the massage water outlet housing 1 and the water jet dish 3 are connected via a foolproof structure. This structural design facilitates the assembly of the massage water outlet housing 1 and the water jet dish 3.

[0030] In this embodiment, the foolproof structure includes a protrusion 14 and a recessed hole 15 that matches the protrusion 14. The protrusion 14 is provided on the massage water outlet housing 1 and / or the water jet dish 3, and correspondingly, the recessed hole 15 is provided on the water jet dish 3 and / or the massage water outlet housing 1. This structural design allows for the positioning and assembly of the massage water outlet housing 1 and the water jet dish 3, and provides good assembly stability.
