Description

Technical Field

[0001] The utility model belongs to the technical field of bathroom products, and particularly relates to a shower head capable of rubbing the back. Background Art

[0002] Bathing is a part of daily life, especially during the humid summer months in southern China, when people may need to shower more than once. A shower head, also known as a showerhead, is a common bathroom cleaning tool that facilitates body rinsing. A shower head typically consists of a head with several water outlets, a grip for holding, and a hose connected to the grip.

[0003] The utility patent application number 201720280089.0 discloses a multifunctional back-scrubbing shower head. By setting a bath towel on the shower head, the shower head can be equipped with a back-scrubbing function. However, the above patent has the following problems: people usually need to use a long-handled back-scrubbing brush to conveniently scrub their backs. If the grip length of the patent is the same as that of a conventional shower head, the arm needs to be bent to an uncomfortable angle to scrub the back, which is inconvenient to exert force and easily fatigues the arm. If the grip length is the same as that of the long-handled back-scrubbing brush, it will affect daily washing. In addition, the bath towel is ring-shaped and has a small effective area. When people use the patent to scrub their backs, some parts of the body cannot be scrubbed or the scrubbing is not in place. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a shower head which is more convenient for back scrubbing than the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a shower head that can scrub the back, comprising a head, a grip and a hose arranged on the side of the grip away from the head, the head is provided with a water outlet and a scrubbing structure, the hose is provided with an extension tube made of hard material, the inner wall of the extension tube is provided with an internal thread one on the side facing the grip, and the side of the grip away from the head is provided with an external thread one that is compatible with the internal thread one.

[0006] Using this solution, when a back scrub is needed, the extension tube is secured to the gripping portion through the engagement of the first internal thread and the first external thread. The shower user grips the extension tube to scrub their back, eliminating the need to bend their hands to an uncomfortable angle as with existing technology. This allows for better force application and provides a more enjoyable back scrubbing experience. When the back scrubbing is no longer needed, the extension tube can be detached from the gripping portion by simply rotating it. The extension tube can be moved along the hose for convenient showering and storage.

[0007] As a further configuration of the present invention, the extension tube is a circular tube, and the center line of the extension tube is an arc line, and the arc of the center line of the extension tube is 0.1 rad to 0.15 rad.

[0008] By adopting the above solution, the extension tube is slightly bent as a whole, which makes it easier to exert force and achieves a better scrubbing effect.

[0009] As a further configuration of the present invention, the extension tube includes at least two sections of extension branch tubes, the internal thread 1 is arranged on the extension branch tube closest to the gripping portion, and the two opposite ends of the adjacent extension branch tubes are respectively provided with an internal thread 2 and an external thread 2 adapted to the internal thread 2.

[0010] With this solution, different bathers can connect one or more extension pipes according to their needs to achieve different lengthening effects. When bathers do not need to scrub their backs, the extension pipes will have less impact on the deformation and movement of the hose.

[0011] As a further configuration of the present invention, an anti-slip pattern is provided on the outer wall of the extended branch pipe.

[0012] The above solution increases friction, makes it easier for people taking a bath to hold the extension tube, prevents slipping during the back scrubbing process, and provides a good back scrubbing effect.

[0013] As a further configuration of the present invention, the length of the extended branch pipe is 5 cm to 10 cm.

[0014] Adopting the above scheme provides good growth effect.

[0015] As a further configuration of the present invention, the scrubbing structure includes a scrubbing panel covering the surface where the water outlet is located, a fixing structure is provided between the scrubbing panel and the head to keep the scrubbing panel and the head relatively fixed, an opening is provided at a position of the scrubbing panel corresponding to the water outlet, and the surface of the scrubbing panel facing away from the water outlet is a rough concave-convex surface or a brush is provided on the surface of the scrubbing panel facing away from the water outlet.

[0016] By adopting the above solution, compared with the prior art, the utility model increases the back scrubbing area without hindering the water outflow from the water outlet.

[0017] As a further configuration of the present invention, the bath scrubbing structure includes a circular fixing part surrounding the bath scrubbing panel, and the fixing structure includes an external thread three arranged on the outer edge of the head, an internal thread three arranged on the inner wall of the fixing part and adapted to the external thread three, a convex column arranged on the surface where the water outlet is located, and a limiting groove arranged on the surface of the bath scrubbing panel facing the water outlet; when the external thread three and the internal thread three are fully matched, the convex column is embedded in the limiting groove.

[0018] This solution offers a simple structure and facilitates assembly and disassembly of the scrubbing panel. To secure the scrubbing panel to the head, engage the third external thread with the third internal thread until the boss engages the retaining groove. The boss and the retaining groove prevent the scrubbing panel from rotating during back scrubbing, ensuring proper operation of the scrubbing assembly.

[0019] As a further configuration of the present invention, the limiting groove is an arc-shaped groove smaller than or equal to a hemisphere, and the protruding column is a spherical segment smaller than or equal to a hemisphere.

[0020] The above solution makes it convenient for the operator to rotate the fixing portion to limit or release the limiting relationship between the boss and the limiting groove.

[0021] As a further configuration of the present invention, the outer wall of the fixing portion is provided with an annular anti-slip layer extending along the circumference of the fixing portion, and the anti-slip layer is composed of anti-slip lines.

[0022] The above solution makes it easy for an operator to apply force to the fixing portion and to rotate the fixing portion.

[0023] The present invention will be further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, the terms "first," "second," and "third" are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0031] The specific implementation of the present invention is as follows Figure 1-4 shown.

[0032] A shower head capable of back scrubbing comprises a head 1, a grip 2, and a hose 3 disposed on the side of the grip 2 facing away from the head 1. In this embodiment, the grip 2 and hose 3 are secured together by a threaded fit. The head 1 is provided with a bath scrubbing structure and a plurality of water outlet holes 11 of varying sizes. The hose 3 is fitted with an extension tube 5 made of a hard material. The inner wall of the extension tube 5 is provided with an internal thread 51 on the side facing the grip 2, and the side of the grip 2 facing away from the head 1 is provided with an external thread 21 that mates with the internal thread 51. When a back scrubbing is required, the extension tube 5 is secured to the grip 2 through the engagement of the internal thread 51 and the external thread 21. When a shower user grips the extension tube 5 to scrub their back, they no longer need to bend their hands to an uncomfortable angle as with conventional shower heads, enabling better exertion and providing a more enjoyable back scrubbing experience. When back scrubbing is no longer required, the extension tube 5 can be detached from the grip 2 by rotating it. The extension tube 5 can be moved along the hose 3 for convenient showering and storage.

[0033] The extension tube 5 is a circular tube, and the center line of the extension tube 5 is an arc line, and the arc of the center line of the extension tube 5 is 0.14 rad. The extension tube 5 is slightly curved as a whole, so that the scrubbing effect is better.

[0034] In this embodiment, the extension tube 5 includes two 7 cm long extension branch tubes 52, and the internal thread 1 51 is set on the extension branch tube 52 closest to the gripping part 2. Each extension branch tube 52 is provided with an anti-slip pattern 523, and the opposite ends of adjacent extension branch tubes 52 are respectively provided with an internal thread 2 521 and an external thread 2 522 adapted to the internal thread 2 521.

[0035] Different bathers can connect one or more extension tubes 52 to achieve different lengthening effects based on their needs. When a bather doesn't need a back scrub, the extension tube 52 provides less obstruction to the deformation and movement of the hose 3. The anti-slip pattern 523 increases friction, making it easier for the bather to grip the extension tube 5, preventing slipping during back scrubbing and providing a superior back scrubbing effect.

[0036] The bath scrubbing structure includes a bath scrubbing panel 41 covering the surface where the water outlet 11 is located, and a circular fixing portion 42 surrounding the bath scrubbing panel 41. The bath scrubbing panel 41 has an opening 411 at a position corresponding to the water outlet 11, and the surface of the bath scrubbing panel 41 facing away from the water outlet 11 is a rough, concave-convex surface. The outer edge of the head 1 is provided with an external thread 3 12, and the inner wall of the fixing portion 42 is provided with an internal thread 3 421 that matches the external thread 3 12. The surface where the water outlet 11 is located is provided with three protrusions 13 that are rotationally symmetrical along the axis of the bath scrubbing panel 41, and the surface of the bath scrubbing panel 41 facing the water outlet 11 is provided with three limiting grooves 422. When the external thread 3 12 and the internal thread 3 421 are fully matched, each protrusion 13 is respectively embedded in a limiting groove 422.

[0037] Compared to existing technologies, this embodiment increases the back-scrubbing area without obstructing water flow from the water outlet 11. To secure the scrubbing panel 41 to the head 1, the external thread 3 12 engages the internal thread 3 421 until the boss 13 engages the retaining groove 422. The boss 13 engages the retaining groove 422 to prevent the scrubbing panel 41 from spinning during scrubbing. The simple structure allows for easy assembly and disassembly.

[0038] The limiting groove 422 is an arc-shaped groove smaller than a hemisphere, and the boss 13 is a spherical segment smaller than a hemisphere, so that the operator can easily rotate the boss 13 to form a limiting relationship with the limiting groove 422 or release the limiting relationship between the two.

[0039] The outer wall of the fixing portion 42 is provided with an annular anti-slip layer 423 extending along the circumference of the fixing portion 42 . The anti-slip layer 423 is composed of anti-slip lines, which facilitates the operator to apply force to the fixing portion 42 and to facilitate the operator to rotate the fixing portion 42 .

[0040] The present invention is not limited to the above-mentioned specific implementation methods. Those skilled in the art can implement the present invention in various other specific implementation methods based on the contents disclosed in the present invention. Any simple changes or modifications made to the design structure and concept of the present invention fall within the scope of protection of the present invention.
