Description

Technical Field

[0001] The present invention relates to the technical field of bathroom products, and in particular to a shower head with a roller that switches water sprays. Background Art

[0002] Traditional showerheads typically have only one water outlet style. As people's living standards continue to improve, showerheads with multiple spray styles are gradually appearing on the market. These multiple-style showerheads require a switchable water outlet style. Existing switchable showerheads on the market typically use a push-button or push-button switching method. By actuating the push-button or push-button, and utilizing the transmission relationship between the push-button or push-button and the showerhead's water distribution plate, the water distribution plate rotates, thereby switching the water distribution style. However, these switching methods require bidirectional movement, requiring either forward or reverse movement to switch the water distribution style, making them relatively simple and inconvenient to use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a shower head with a roller for switching water sprays, which can switch the water spray styles using a unidirectional rotating roller and is easy to use.

[0004] In order to solve the above technical problems, the present invention provides a shower head with a roller-switching water spray, comprising a shell, a water inlet assembly, a rolling switching assembly, a water distribution assembly and a water outlet assembly, the shell comprising a handle, the water inlet assembly comprising a water inlet pipe arranged in the handle, the water distribution assembly comprising a water distribution chamber and a water distribution hole, the water outlet assembly comprising at least two water outlet channels, the water inlet pipe being connected to the water distribution chamber, the water distribution chamber being able to be connected to the water outlet channel through the water distribution hole, and the water distribution hole being able to adjust the flow rate of water reaching the water outlet channel when rotating.

[0005] The rolling switching assembly includes a roller and a connecting rod. The roller is hinged to the side of the water inlet pipe. The central axis of the roller passes through the water inlet pipe from the side of the water inlet pipe. The side edge of the roller can expose the outer wall of the handle. The shower head with a roller switching water spray also includes a transmission assembly. When the roller rotates unidirectionally, it can drive the connecting rod to move back and forth through the transmission assembly. The connecting rod can drive the water diversion hole to rotate and perform stepless switching in each of the water outlet channels.

[0006] As an improvement of the above-mentioned scheme, the transmission assembly includes a sliding hole provided on the connecting rod and a driving protrusion provided on the roller. The side of the roller is provided with a limiting groove, and the driving protrusion is fixed in the limiting groove. The side of the driving protrusion protrudes from the side of the roller. The driving protrusion can be inserted into the sliding hole, and the side of the driving protrusion can push the inner side wall of the sliding hole to move back and forth, so that the connecting rod moves back and forth in a direction close to or away from the water diversion chamber.

[0007] As an improvement to the above-mentioned solution, a tooth claw is provided on the side of the driving protrusion, and the tooth claw protrudes from the side of the driving protrusion. The inner side wall of the sliding hole is provided with a first rack and a second rack. The first rack and the second rack are respectively arranged on opposite sides of the sliding hole. When the roller rotates unidirectionally, the tooth claw can engage with the first rack and the second rack separately in turn.

[0008] As an improvement to the above solution, the tooth claw is arranged on one side of the driving protrusion, and the driving protrusion is coaxially arranged with the roller.

[0009] As an improvement to the above solution, the driving protrusion is eccentrically arranged with respect to the roller, the surface of the driving protrusion and the inner side wall of the sliding hole are both smoothly arranged, and the driving protrusion can slide back and forth on the inner side wall of the sliding hole.

[0010] As an improvement to the above solution, the length direction of the sliding hole is perpendicular to the movement direction of the connecting rod, and the driving protrusion can move up and down relative to the connecting rod in the sliding hole.

[0011] As an improvement of the above solution, the water distribution component also includes a water distribution plate, the water distribution hole is provided on the water distribution plate, the water inlet component also includes a fixing seat, the fixing seat is connected to the water inlet pipe, and the center of the water distribution plate is hinged to the fixing seat.

[0012] As an improvement to the above solution, there are two water diversion holes, which are respectively arranged on opposite sides of the water diversion plate. When rotating, the water diversion holes can produce changes in the flow cross-sectional area with the solid part of the water diversion cavity.

[0013] As an improvement of the above solution, the rolling switching assembly also includes a push rod, one end of which is provided with a hinge column, the hinge column protrudes upward, the hinge column is hinged to the connecting rod, and the end of the push rod away from the hinge column is hinged to one side of the water diversion plate.

[0014] As an improvement to the above solution, the water outlet channel includes a first channel, a second channel and a third channel arranged in sequence.

[0015] A single water diversion hole can be communicated with the first channel alone, or two water diversion holes can be communicated with the first channel at the same time, or two water diversion holes can be communicated with the second channel at the same time, or two water diversion holes can be communicated with the third channel at the same time.

[0016] The implementation of the present invention has the following beneficial effects:

[0017] The present invention provides a shower head with a roller-type water-spray switch, comprising a housing, a rolling switching assembly, a water-dividing assembly, and a water-distributing assembly. The housing comprises a handle, the water-dividing assembly comprises a water-dividing chamber and a water-dividing hole, the water-distributing assembly comprises at least two water-distributing channels, the water-dividing chamber can be connected to the water-distributing channels through the water-dividing hole, the rolling switching assembly comprises a roller and a connecting rod, the side edge of the roller can be exposed from the outer wall of the handle, and the rolling switching assembly further comprises a transmission assembly, the roller can drive the connecting rod to move back and forth through the transmission assembly when rotating unidirectionally, and the connecting rod can drive the water-dividing hole to switch sequentially between the various water-distributing channels. Therefore, when in use, the user can operate the shower head while holding the handle, and by rotating the roller unidirectionally, the user can control the switching of the water-spray patterns by switching the different water-distributing channels in sequence, without having to switch the water-spray patterns by repeatedly moving the roller back and forth, which is more convenient to use. Moreover, when the water diversion hole rotates, the flow rate can be changed by changing the area of ​​the water outlet cross-section, thereby changing the flow rate of various water splash patterns. Since the water diversion hole rotates continuously, it can form an effect of infinitely adjusting the water splash pattern and water splash flow rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0025] See also Figure 1 、 Figure 2 and Figure 3The first embodiment of the present invention discloses a shower head with a roller 21 for switching water spray, comprising a housing 6, a water inlet assembly 1, a scroll switching assembly 2, a water distribution assembly 3 and a water outlet assembly 4. The housing 6 includes a handle 61, the water inlet assembly 1 includes a water inlet pipe 11 arranged in the handle 61, the water distribution assembly 3 includes a water distribution chamber 31 and a water distribution hole 32, the water outlet assembly 4 includes a nozzle 41 and at least two water outlet channels 42, the water inlet pipe 11 is connected to the water distribution chamber 31, the water distribution hole 32 can adjust the flow rate of water reaching the water outlet channel 42 when rotating, and when the water distribution hole 32 rotates, the water outlet cross-sectional area between the water distribution hole 32 and the water outlet channel 42 will change, thereby forming a change in flow rate. Water enters the water diversion chamber 31 from the water inlet pipe 11. The water diversion chamber 31 can be connected to the water outlet channel 42 through the water diversion hole 32. The water diversion hole 32 can be moved. By moving the water diversion hole 32, the water diversion hole 32 can be connected to different water outlet channels 42, so that water enters the water outlet channel 42 from the water diversion chamber 31. Different water outlet channels 42 correspond to different water splash patterns, so that water can finally spray out different patterns of water splashes from the nozzle 41. In order to achieve the switching of splash styles, the rolling switching assembly 2 includes a roller 21 and a connecting rod 22. The connecting rod 22 is connected between the roller 21 and the water diversion chamber 31. The roller 21 is hinged to the side of the water inlet pipe 11. In this embodiment, the central axis of the roller 21 passes through the water inlet pipe 11 from the side of the water inlet pipe 11, so that the driving force parallel to the length direction of the handle 61 can drive the roller 21 to roll. In order to facilitate the use of the roller 21, the side edge of the roller 21 can expose the outer wall of the handle 61. In order to realize the function of switching water splashes by unidirectional rotation, the shower head for switching water splashes by the roller 21 further includes a transmission assembly 5. When the roller 21 rotates unidirectionally, the transmission assembly 5 can drive the connecting rod 22 to move back and forth. During the reciprocating movement of the connecting rod 22, the connecting rod 22 can drive the water diversion hole 32 to switch in each of the water outlet channels 42 in sequence, thereby completing the unidirectional rotation of the roller 21 and driving the water diversion hole 32 to switch the water splash in sequence.

[0026] The beneficial effects of the first embodiment of the present invention are as follows:

[0027] The shower head with a roller 21 for switching water sprays in an embodiment of the present invention is provided with a shell 6, a rolling switching component 2, a water diversion component 3 and a water outlet component 4, wherein the shell 6 includes a handle 61, the water diversion component 3 includes a water diversion chamber 31 and a water diversion hole 32, and the water outlet component 4 includes at least two water outlet channels 42, and the water diversion chamber 31 can be connected to the water outlet channel 42 through the water diversion hole 32, the rolling switching component 2 includes a roller 21 and a connecting rod 22, and the side edge of the roller 21 can expose the outer wall of the handle 61, and the rolling switching component 2 also includes a transmission component 5, and the roller 21 can drive the connecting rod 22 to move back and forth through the transmission component 5 when rotating in one direction, and the connecting rod 22 can drive the water diversion hole 32 to switch in each of the water outlet channels 42 in sequence. Therefore, when in use, the user can control the device by simply gripping the handle 61. Furthermore, by rotating the roller 21 in one direction, the user can control the switching of the water spray patterns by sequentially switching the different water outlet channels 42, eliminating the need to repeatedly move the roller back and forth to switch the water spray patterns, making it more convenient to use. Furthermore, when the water diversion hole 32 rotates, it can change the flow rate by changing the area of ​​the water outlet cross-section, thereby changing the flow rate of various water spray patterns. Because the water diversion hole 32 rotates continuously under the drive of the roller 21, it can achieve the effect of infinitely adjusting the water spray pattern and water flow rate.

[0028] Specifically, the transmission assembly 5 includes a sliding hole 51 provided on the connecting rod 22 and a driving protrusion 52 provided on the roller 21. The driving protrusion 52 and the roller 21 can be integrated or assembled separately. In this embodiment, the driving protrusion 52 is provided separately from the roller 21. A limiting groove 211 is provided on the side of the roller 21. The driving protrusion 52 is fixed in the limiting groove 211. The limiting groove 211 is provided with a limiting latch that can limit the driving protrusion 52, so that the roller 21 can drive the limiting protrusion to rotate together. Preferably, the driving protrusion 52 is coaxial with the roller 21, and the rotational angular velocity of the roller 21 is the same as the rotational angular velocity of the driving protrusion 52. The side of the driving protrusion 52 protrudes from the side of the roller 21 to facilitate connection with the connecting rod 22. The driving protrusion 52 can be inserted into the sliding hole 51. When the roller 21 rotates, it drives the driving protrusion 52 to rotate. During the rotation of the driving protrusion 52, the side of the driving protrusion 52 can push the inner side wall of the sliding hole 51 to reciprocate. The sliding hole 51 drives the connecting rod 22 to move, ultimately causing the connecting rod 22 to reciprocate in a direction toward or away from the water diversion chamber 31. After the connecting rod 22 moves, it can drive the water diversion hole 32 to switch between different water outlet channels 42.

[0029] In the first embodiment of the present invention, a toothed claw 521 is provided on the side of the driving protrusion 52. The toothed claw 521 protrudes from the side of the driving protrusion 52. The inner sidewall of the sliding hole 51 is provided with a first rack 511 and a second rack 512. The first rack 511 and the second rack 512 are respectively provided on opposite sides of the sliding hole 51. In this embodiment, the first rack 511 and the second rack 512 are respectively provided on the upper and lower sides of the sliding hole 51. The shape of the toothed claw 521 corresponds to the shape of the first rack 511 and the second rack 512. When the roller 21 rotates unidirectionally, the toothed claw 521 can engage with the first rack 511 and the second rack 512 in sequence. Specifically, the driving protrusion 52 is coaxially arranged with the roller 21, and the tooth claws 521 are not arranged on the entire circumferential edge of the driving protrusion 52, but are only arranged on one side of the driving protrusion 52. Since there are only a small number of tooth claws 521, the tooth claws 521 on this side can only engage with the first rack 511 or the second rack 512 alone. During the unidirectional rotation of the roller 21, see Figure 4 As the roller 21 rotates clockwise, the toothed claw 521 is first in meshing with the first rack 511. As the rotation continues, the toothed claw 521 gradually rolls to the end of the first rack 511, and the connecting rod 22 moves away from the water diversion chamber 31. After reaching the end, the toothed claw 521 ends its meshing with the first rack 511 and prepares to transition to the meshing state of the second rack 512. Figure 5 As the clockwise rotation continues, the claw 521 contacts the end of the second rack 512, and the connecting rod 22 is then driven to move toward the water diversion chamber 31. As the connecting rod 22 reciprocates toward or away from the water diversion chamber 31, the roller 21 maintains unidirectional rotation, and the water diversion holes 32, driven by the connecting rod 22, are sequentially switched to communicate with the predetermined water outlet channels 42.

[0030] In order to enable the connecting rod 22 to drive the water diversion hole 32 to switch, the water diversion assembly 3 also includes a water diversion plate 33. The water diversion hole 32 is provided on the water diversion plate 33. The water inlet assembly 1 also includes a fixed seat 12. The fixed seat 12 is connected to the water inlet pipe 11. The center of the water diversion plate 33 is hinged to the fixed seat 12, so that the water diversion plate 33 can rotate relative to the fixed seat 12. The water diversion chamber 31 is located in the fixed seat 12, and the water diversion plate 33 is located in the water diversion chamber 31. The roller 21 is hinged to the side of the fixed seat 12. In this embodiment, the number of the water diversion holes 32 is two, and the two water diversion holes 32 are respectively provided on opposite sides of the water diversion plate 33. In other embodiments, there may be more than two. The water diversion hole 32 can produce a change in the flow cross-sectional area with the solid part of the water diversion chamber 31 when rotating. The water diversion chamber 31 is provided with a water inlet of the water outlet channel 32, and the water inlets are arranged at intervals. In each interval, the water diversion hole 32 can form a water outlet with a continuously changing flow cross-sectional area with the interval when rotating, thereby changing the flow rate flowing into the water outlet channel 32 to achieve the effect of controlling the flow rate of the water splash pattern. In order to completely convert the moving direction of the connecting rod 22 into a horizontal moving direction, the rolling switching assembly 2 also includes a push rod 23, one end of the connecting rod 22 is provided with a hinge column 221, and the hinge column 221 protrudes upward. The hinge column 221 is hinged to the push rod 23, and the end of the push rod 23 away from the hinge column 231 is hinged to one side of the water diversion plate 33. Since there is a certain angle between the handle 61 and the shell 6, the connecting rod 22 will have an up and down direction offset during the movement. In order to offset these offsets, the push rod 23 and the hinge column 231 adopt a hinged form that can move up and down. During the up and down movement of the connecting rod 22, its displacement will be released through the up and down movement of the hinge column 231, thereby not driving the push rod 23 to move up and down, to ensure that the push rod 23 only transmits horizontal displacement and does not transmit up and down displacement. During the movement of the push rod 23, the push rod 23 can drive the hinge point between the push rod 23 and the water diversion plate 33 to move. The hinge point is located at the eccentric position of the water diversion plate 33, so the water diversion plate 33 can rotate, thereby driving the movement and switching of the water diversion hole 32.

[0031] In this embodiment, the water outlet channel 42 includes a first channel 421, a second channel 422 and a third channel 423 arranged in sequence, and different channels correspond to different water outlet patterns. In this embodiment, by rotating the water diversion hole 32, the two water diversion holes 32 can be connected to the first channel 421 and the second channel 422 at the same time, and continue to rotate, the two water diversion holes 32 can be connected to the first channel 421 at the same time, and continue to rotate, the two water diversion holes 32 can be connected to the second channel 422 at the same time, and continue to rotate, the two water diversion holes 32 can be connected to the third channel 423 at the same time. Through the unidirectional rotation of the roller 21, the water diversion hole 32 can switch between the first channel 421, the second channel 422 and the third channel 423 in sequence to form different water splash patterns.

[0032] See also Figure 6 The present invention also discloses a second embodiment. In the second embodiment, the driving protrusion 52 is eccentrically arranged with the roller 21, and the roller 21 can drive the driving protrusion 52 to swing around the hinge point of the roller 21 when it rotates. The surface of the driving protrusion 52 and the inner side wall of the sliding hole 51 are both smoothly arranged, and the driving protrusion 52 can slide back and forth on the inner side wall of the sliding hole 51. When the roller 21 rotates unidirectionally, the driving protrusion 52 will swing with the roller 21 and can slide on the inner side wall of the sliding hole 51. During the sliding process, the connecting rod 22 can be driven to move back and forth through the sliding hole 51. Since the distance between the driving protrusion 52 and the water diversion chamber 31 will repeatedly change between increasing and decreasing when it swings, the connecting rod 22 will also reciprocate in the direction of approaching or moving away from the water diversion chamber 31. In order to prevent the driving protrusion 52 from driving the sliding hole 51 to move up and down when it moves up and down, the length direction of the sliding hole 51 is perpendicular to the movement direction of the connecting rod 22, so that the driving protrusion 52 has the freedom to move up and down relative to the sliding hole 51. Therefore, the driving protrusion 52 can move up and down relative to the connecting rod 22 in the sliding hole 51 without driving the connecting rod 22, so that the connecting rod 22 can only move in one direction.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
