Description

Technical area

[0001] The utility model relates to the technical field of sanitary products and, in particular, to a rod-shaped shower head. Background technology

[0002] A conventional shower head comprises a water distribution chamber, several water drainage channels, and a water drainage nozzle assigned to each water drainage channel. All water drainage nozzles are arranged in zones on the water drainage cover. By activating a rotating or moving water distribution element located in the water distribution chamber, a specific water drainage channel is connected to the water distribution chamber, so that the water drainage nozzles discharge water in the corresponding area. Due to the limited surface area of the water drainage cover, the water drainage area of each water drainage channel decreases as the number of water drainage channels increases.This situation is particularly pronounced with bar-shaped shower heads (elongated shower heads), as the water outlet nozzles are mounted on the side panel facing the user, leaving only a very limited area for the arrangement of the water outlet nozzles. Increasing the number of channels on this basis further reduces the water outlet area of each channel, resulting in insufficient shower performance and impairing the user experience. Content of the utility model

[0005] As a further optimization, a water stop portion is provided on the water distribution element, wherein the water stop portion serves to seal the water inlet end of the water drainage channel, wherein one end of the water distribution element is arranged in the water distribution chamber, while the other end is connected to a push and select structure and is designed to be driven to rotate by the push and select structure.

[0006] As a further optimization, the push and select structure comprises a push button and a sliding block connected to the push button, wherein the sliding block is provided with a rack, wherein the water distribution element is provided with a gear for engaging with the rack.

[0007] As a further optimization, a limiting groove is provided at the bottom of the water distribution element, wherein the limiting groove is inserted into the positioning section of the water distribution chamber in order to limit the rotation angle of the water distribution element.

[0008] As a further optimization, the water distribution chamber is arranged perpendicular to the axis of the shower, with both the water inlet channel and the water outlet channel running along the axis of the shower.

[0009] As a further optimization, the water drainage assembly comprises a water inlet pipe, a flow element and a water drainage cover, wherein the water inlet pipe is equipped with a water inlet channel, a first water drainage channel, a second water drainage channel and a water distribution chamber which is connected to all of the said channels, wherein a plurality of first water drainage openings are arranged on the side wall of the first water drainage channel, wherein a plurality of second water drainage openings are arranged on the side wall of the second water drainage channel, wherein a first flow chamber is formed between the water drainage cover and the flow element, wherein a second flow chamber is formed between the water inlet pipe and the flow element, wherein the first flow chamber communicates with the first water drainage opening, wherein the second flow chamber communicates with the second water drainage opening.

[0010] As a further optimization, water drainage nozzles are arranged on the water drainage cover, wherein a water inlet groove and a water inlet opening are provided on the underside of each water drainage nozzle, wherein the water inlet groove is arranged in a tangential direction to the water inlet opening, wherein the water flow in the first flow chamber exits the water drainage nozzle via the water inlet groove, while the water flow in the second flow chamber exits the water drainage nozzle via the water inlet opening.

[0011] As a further optimization, the outer enclosure of the water drainage assembly is nested with a metal housing, the metal housing being cylindrical in shape, the water drainage assembly being configured to be inserted into the metal housing from one end of the metal housing and to be defined by an insert at the opposite end of the metal housing.

[0012] As a further optimization, the insert is inserted on the side of the water drain assembly opposite the water drain nozzle and a first locking portion is provided on this, wherein a second locking portion is arranged on the water drain assembly, wherein the first locking portion cooperates with the second locking portion to axially limit the water drain assembly and to position the water drain assembly so that the water drain nozzle is inserted accordingly into the mounting hole of the metal housing.

[0013] For further improvement, a limiting portion is provided on the water drain assembly, wherein a positioning hole is provided on the metal housing, wherein the limiting portion engages with the positioning hole to limit the water drain assembly in the circumferential direction, wherein the inner wall of the metal housing is concavely provided with a clamping slot, wherein a snap lock is provided on the water drain assembly, wherein the snap lock engages with the clamping slot to limit the water drain assembly in the axial direction.

Starting from the embodiments of the present utility model, all other embodiments achieved by a person skilled in the art without creative work fall within the scope of the present utility model. Therefore, the following detailed description of the embodiment of the present utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents the selected embodiment of the present utility model.Starting from the embodiments of the present utility model, all other embodiments achieved by a person skilled in the art without creative work fall within the scope of protection of the present utility model. Example

[0018] In connection with the Fig. 1 to 18, in this embodiment, a rod-shaped shower head is provided which comprises a water drainage assembly 1, wherein the water drainage assembly 1 has a water inlet channel 11, a water distribution chamber 12, a water drainage channel and a water drainage nozzle 15, wherein the water inlet channel 11 communicates with the water distribution chamber 12, wherein a water distribution element 2 is arranged in the water distribution chamber 12, wherein it is operated in an operable manner that the water distribution element 2 is moved or rotated in order to select the water drainage channel connected to the water inlet channel 11, wherein all the water drainage nozzles 15 are arranged along the axis of the shower head, wherein each individual water drainage nozzle 15 is connected to at least two different water drainage channels, wherein each water drainage channel forms a different water jet in cooperation with the respective water drainage nozzle 15.

[0019] It should be noted that in the present embodiment, the same water outlet nozzle 15 is connected to at least two different water outlet channels. A water distribution element 2 selects the water outlet channel that is permeable to the water inlet channel 11 to generate different water jet shapes at the water outlet nozzle 15 and thus enable a change of gear. It is easy to understand that the same water outlet nozzle 15 can generate different water jet types, whereby the water outlet areas remain the same in the individual gears. This ensures a constant water outlet area and thus safeguards the shower performance, which improves the shower experience for the user.

[0020] In a preferred embodiment, a water stop portion 21 is provided on the water distribution element 2, wherein the water stop portion 21 serves to seal the water inlet end of the water drainage channel, wherein one end of the water distribution element 2 is arranged in the water distribution chamber 12, while the other end is connected to a push and select structure 3 and is configured to be driven to rotate by the push and select structure 3. For example, two water drainage channels are arranged on the water drainage assembly 1, namely the first water drainage channel 13 and the second water drainage channel 14. When the water stop portion 21 closes the inlet end of the first water drainage channel 13, the first water drainage channel 13 is separated from the water inlet channel 11.In this case, the second water drainage channel 14 communicates with the water inlet channel 11, and the water drainage nozzle 15, together with the second water drainage channel 14, forms a second type of water splash. When the water stop section 21 closes the second water drainage channel 14, the second water drainage channel 14 is separated from the water inlet channel 11. Then, the first water drainage channel 13 communicates with the water inlet channel 11, and the water drainage nozzle 15, together with the first water drainage channel 13, forms a first type of water splash. When the water stop section 21 simultaneously closes part of the first water drainage channel 13 and part of the second water drainage channel 14, a third type of water splash is created between the two water drainage channels and the water drainage nozzle 15. This is not to be understood as exhaustive and does not represent a specific limitation.

[0021] The push and select structure 3 further comprises a push button 31 and a sliding block 32 connected to the push button 31. The sliding block 32 is provided with a rack 321, and the water distribution element 2 is provided with a gear 22 for engaging the rack 321. The sliding block 32 is mounted on the water outlet assembly 1. When the user manually operates the push button 31, the sliding block 32 moves along the axis of the shower head, causing the rack 321 to synchronously drive the gear 22. This causes the water distribution element 2 to move, enabling continuous adjustment of the water outlet paths. Preferably, a limiting groove 23 is provided at the bottom of the water distribution element 2, wherein the limiting groove 23 is inserted into the positioning section 121 of the water distribution chamber 12 in order to limit the angle of rotation of the water distribution element 2 and thus facilitate the gear selection for the user.

[0022] Based on the above-mentioned embodiments, in an optional embodiment of this utility model, the water distribution chamber 12 is arranged perpendicular to the axis of the shower, with both the water inlet channel 11 and the water outlet channel running along the axis of the shower, in order to enable a more compact structure, avoid the intersection of the water channels, simplify the water piping structure, and facilitate the mold design.

[0023] In one embodiment, the water drainage assembly 1 comprises a water inlet pipe 16, a flow element 17 and a water drainage cover 18, wherein the water inlet pipe 16 is equipped with a water inlet channel 11, a first water drainage channel 13, a second water drainage channel 14 and a water distribution chamber 12 which is connected to all of the said channels, wherein a plurality of first water drainage openings 131 are arranged on the side wall of the first water drainage channel 13, wherein a plurality of second water drainage openings 141 are arranged on the side wall of the second water drainage channel 14, wherein a first flow chamber 132 is formed between the water inlet pipe 16 and the flow element 17, wherein a second flow chamber 142 is formed between the water inlet pipe 16 and the flow element 17, wherein the first flow chamber 132 communicates with the first water drainage opening 131,The second flow chamber 142 communicates with the second water outlet opening 141. The water flow from the first water outlet channel 13 flows through the first water outlet opening 131 into the first flow chamber 132, while the water flow from the second water outlet channel 14 flows through the second water outlet opening 141 into the second flow chamber 142. The first water outlet opening 131 and the second water outlet opening 141 are each arranged so that they are evenly distributed along the axis of the shower head to ensure a uniform water flow at all positions.

[0024] Furthermore, water outlet nozzles 15 are arranged on the water outlet cover 18, wherein a water inlet groove 181 and a water inlet opening 182 are provided on the underside of each water outlet nozzle 15, wherein the water inlet groove 181 is arranged in a tangential direction to the water inlet opening 182, wherein the water flow in the first flow chamber 132 exits the water outlet nozzle 15 via the water inlet groove 181, while the water flow in the second flow chamber 142 exits the water outlet nozzle 15 via the water inlet opening 182. That is, when the first water outlet channel 13 is connected to the water inlet channel 11, see curve A in Fig. 2, the water flow flows from the first water outlet channel 13 to the first flow chamber 132 and then enters the water outlet nozzle 15 via the water inlet groove 181. The water is accelerated in the water inlet groove 181, creating a massage flow (first water splash) at the water outlet nozzle 15. If the second water outlet channel 14 is connected to the water inlet channel 11, see curve B in Fig. 2, the water flow flows from the second water outlet channel 14 to the second flow chamber 142 and then enters the water outlet nozzle 15 via the water inlet opening 182. The water is ejected directly from the water outlet nozzle 15 as a second water spray. When both water outlet channels are connected to the water inlet channel 11, a third water spray is created at the water outlet nozzle 15, which is a combination of the first and second water sprays.

[0025] Based on the above-mentioned embodiments, in an optional embodiment of this utility model, the outer casing of the water drainage assembly 1 is nested with a metal casing 4, the metal casing 4 being cylindrical in shape, and the water drainage assembly 1 being configured to be inserted into the metal casing 4 from one end thereof and to be defined by an insert 5 at the opposite end of the metal casing 4. The material of the metal casing 4 may be zinc alloy, stainless steel, or the like. Since the metal casing 4 is directly placed on the water drainage assembly 1 without any particular limitation and no water flows through it, the choice of materials is wider, which facilitates the design of the external appearance.

[0026] In particular, the insert 5 is inserted on the side of the water drainage assembly 1 opposite the water drainage nozzle 15, and a first locking portion 51 is provided thereon. A second locking portion 19 is arranged on the water drainage assembly 1. The first locking portion 51 cooperates with the second locking portion 19 to axially limit the water drainage assembly 1 and to abut the water drainage assembly 1, so that the water drainage nozzle 15 is inserted into the mounting hole 41 of the metal housing 4. The first locking portion 51 is an elastic snap closure in the shape of a pretzel, and the second locking portion 19 has a guide surface compatible with the pretzel shape to enable the smooth insertion of the insert 5. The adjustment of the insert 5 serves, on the one hand, to limit the axial movement of the water drainage assembly 1 and, on the other hand, to facilitate the installation of the water drainage nozzle 15.During installation, the water drain assembly 1 is first inserted into the metal housing 4. At this point, there is still sufficient space in the metal housing 4 to accommodate the water drain nozzle 15 and prevent the water drain nozzle 15 from being scratched by the metal housing 4. After the water drain assembly 1 has been correctly positioned, the insert 5 is then inserted into the metal housing 4 so that the water drain nozzle 15 can be inserted along the mounting hole 41, ensuring easy installation.

[0027] According to the method, a limiting portion 161 is provided on the water drain assembly 1, a positioning hole 42 is provided on the metal housing 4, the limiting portion 161 engaging with the positioning hole 42 to limit the water drain assembly 1 in the circumferential direction, the inner wall of the metal housing 4 being concavely provided with a clamping slot 43, a snap fastener 162 being located on the water drain assembly 1, the snap fastener 162 engaging with the clamping slot 43 to limit the water drain assembly 1 in the axial direction.
