Description

Technical Field

[0001] The utility model relates to an overhead shower, belonging to the technical field of sprinklers with multiple outlet holes. Background Art

[0002] An overhead shower is a shower head located above the head during use. Due to its wide spraying range and adjustable angle, it is widely favored by consumers. For example, a self-cleaning oxygen-containing overhead shower disclosed in a Chinese utility model patent with the authorization announcement number CN203108678U includes a fixed seat, a gland, a spring, a water distributor, a face cover, a gasket and a body. The fixed seat and the body are threadedly connected to form an accommodation cavity, and the water distributor is located in the accommodation cavity. The face cover includes a disc body and a support column connected to the center of the disc body. A plurality of water outlet holes are provided on the disc body. The support column passes through the water distributor and is connected to the gland. The spring is sleeved outside the support column, and one end of the spring abuts against the gland and the other end abuts against the water distributor. Cleaning needles corresponding to the water outlet holes on the disc body are provided on the water distributor. During use, in the state where the water flow is closed, the face cover is in the upper position under the action of the spring. At this time, each cleaning needle is inserted into the corresponding water outlet hole. When the water flow is opened, the water flow pressure pushes the gland and the face cover downward, so that the water outlet hole is separated from the cleaning needle. At this time, the overhead shower can discharge water. When the water flow is closed, the gland and the face cover reset upward, and the cleaning needle is inserted into the corresponding water outlet hole again, and the dirt and impurities in the water outlet hole are removed, realizing the self-cleaning function.

[0003] The above-mentioned overhead shower has a large number of components, a very complex structure, and of course a relatively high cost. During use, any component failure requires repair, and the failure rate is relatively high. In addition, after long-term use, the spring is prone to rust, so that the initially sprayed water will contain rust. In addition, the water outlet holes of the existing overhead shower are straight downward sprays. The spraying range is ensured by setting a relatively large body and fixed seat, and then installing a relatively large face cover and setting as many water outlet holes as possible (generally more than five circles) on the face cover. The large number of water outlet holes will cause the sprayed water pressure to decrease and at the same time cause waste of water resources. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an overhead shower to solve the problems that the existing overhead shower has a large number of components, resulting in a complex structure, high cost, high failure rate, and the water outlet holes of the existing overhead shower are straight downward sprays and a relatively large face cover is used to set as many water outlet holes as possible, resulting in a decrease in water pressure and waste of water resources.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A top spray shower head, comprising an upper cover and a lower cover detachably connected together. An inlet connection structure for connecting with a water pipe is provided at the top of the upper cover. The inlet connection structure communicates with the inner cavities of both the upper cover and the lower cover. The lower cover includes a water outlet plate, and one to three circles of through water outlet holes are provided on the water outlet plate. Each circle of water outlet holes has a plurality of them and is evenly distributed. Each water outlet hole directly communicates with the inner cavities of the upper cover and the lower cover. At least the outermost circle of water outlet holes is an inclined hole that gradually inclines downward in a direction away from the center of the water outlet plate.

[0007] The beneficial effects of the above technical solution are as follows: The present utility model belongs to an invention creation with element changes. Firstly, the lower cover (equivalent to the face cover in the prior art) and the upper cover (equivalent to the fixed seat in the prior art) are directly detachably connected, changing the installation method of the lower cover, and the lower cover changes from movable to stationary. At the same time, each water outlet hole on the lower cover directly communicates with the inner cavities of the upper cover and the lower cover, eliminating components such as a water distributor, gland, and spring in the prior art, reducing the number of components, simplifying the structure, and can reduce costs and failure rates. And at least the outermost circle of water outlet holes is an inclined hole that gradually inclines downward in a direction away from the center of the water outlet plate. In this way, the sprayed water is in a radial shape, forming an outward diffusion effect, having a larger coverage range, and being easier to cover the human body. Therefore, only one to three circles of water outlet holes need to be provided, without the need to set many circles. Compared with the prior art, the number of water outlet holes can be reduced, thereby improving the problems of reduced water pressure and wasted water resources.

[0008] Further, the thickness of the water outlet plate is 3 - 5 mm, and the angle between the axis of the water outlet hole and the vertical center line passing through the center of the water outlet plate is 1.5 - 2.5°.

[0009] Further, only one circle of water outlet holes is provided, and each water outlet hole is evenly distributed on a circumference with a diameter of 40 - 45 mm. The central angle between adjacent two water outlet holes is 12°, 15°, or 18°, and the aperture of the water outlet hole is 1 - 1.5 mm.

[0010] Further, the lower cover includes an annular cover body, the annular cover body is detachably connected with the upper cover, the water outlet plate is connected to the lower end of the annular cover body and together with the annular cover body encloses the inner cavity of the lower cover. The lower cover further includes a cover edge connected to the annular cover body and protruding downward from the water outlet plate, and the height of the cover edge is less than the height of the annular cover body.

[0011] Further, the outer peripheral dimensions of the annular cover body and the cover edge are equal, and the inner hole of the cover edge is a tapered hole with a gradually increasing aperture from top to bottom, and the minimum aperture of the tapered hole is greater than the inner hole diameter of the annular cover body.

[0012] Further, the upper cover includes a cylindrical section, an interface section, and a transition section connecting the cylindrical section and the interface section. The interface section is provided with the water inlet connection structure. The outer diameter of the interface section is smaller than that of the cylindrical section. The cylindrical section is detachably connected to the lower cover and the cylindrical section has an outer peripheral surface with the same diameter as that of the lower cover. After the upper cover and the lower cover are connected in place, the outer peripheral surface of the cylindrical section is aligned with the outer peripheral surface of the lower cover and the total height of the upper cover and the lower cover is greater than the outer diameter of the lower cover.

[0013] Further, an internal thread is provided on the inner wall of the lower cover. The cylindrical section of the upper cover is stepped and includes a large-diameter part and a small-diameter part. The large-diameter part is connected to the transition section and the outer diameter of the large-diameter part is equal to the outer diameter of the lower cover. The small-diameter part is provided with an external thread adapted to the internal thread on the inner wall of the lower cover.

[0014] Further, a stepped surface is formed between the large-diameter part and the small-diameter part. An installation groove for installing a sealing ring is provided on one of the upper end surface of the lower cover and the stepped surface.

[0015] Further, the water outlet plate is circular and the diameter of the water outlet plate is 55 - 60 mm.

[0016] Further, the included angle between the axis of the water outlet hole and the vertical center line passing through the center of the water outlet plate is 2°. Description of the Drawings

[0027] The features and performance of the present utility model will be further described in detail below in conjunction with the embodiments.

[0028] Aiming at the technical problems in the prior art, the technical concept of the present utility model is to eliminate components such as the water distributor, gland, and spring in the prior art, so that the lower cover (i.e., the face cover in the prior art) is directly detachably connected to the upper cover (i.e., the fixed seat in the prior art), the lower cover no longer moves, and the structure is simpler; at the same time, at least the outermost water outlet holes are set as inclined holes that gradually tilt away from the center of the water outlet plate from top to bottom, so that the sprayed water is in a radial shape, forming an outward diffusion effect, thereby having a larger coverage range, reducing the number of water outlet holes, and improving the problems of reduced water pressure and wasted water resources.

[0029] Embodiment 1 of the overhead shower of the present utility model:

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the overhead shower includes a lower cover 1, a sealing ring 2, an upper cover 3, a sealing gasket 4, a compression nut 5, a filter screen 6, and a ball joint 7. Among them, the upper cover 3 and the lower cover 1 are detachably connected together, and the specific detachable connection method is a threaded connection. In this embodiment, in combination with Figure 6 and Figure 7As shown in the figure, the lower cover 1 includes an annular cover body 12 and a water outlet plate 11. The annular cover body 12 is detachably connected to the upper cover 3. Specifically, an internal thread 121 is provided on the inner wall of the annular cover body 12. The water outlet plate 11 is connected to the lower end of the annular cover body 12. The water outlet plate 11 and the annular cover body 12 jointly enclose the inner cavity of the lower cover 1. A circle of through water outlet holes 111 is provided on the water outlet plate 11. There are multiple water outlet holes 111 in the circle and they are evenly distributed. Each water outlet hole 111 is an inclined hole that gradually inclines away from the center of the water outlet plate 11 from top to bottom. In this way, the sprayed water is in a radial shape, forming an outward diffusion effect, which can have a larger coverage range and can cover the human body. Therefore, it is not necessary to set many circles of water outlet holes 111 to meet people's shower needs, which greatly reduces the number of water outlet holes set compared with the prior art, thereby improving the problems of reduced water pressure and wasted water resources.

[0031] Furthermore, the thickness of the water outlet plate 11 is 3 - 5 mm, and the angle between the axis of the water outlet hole 111 and the vertical center line passing through the center of the water outlet plate 11 is 1.5 - 2.5°. The thickness of the water outlet plate 11 determines the length of the water outlet hole 111. Coupled with the inclination degree of the water outlet hole 111, the diffusion degree of the sprayed water, that is, the shower coverage range, can be determined. The water outlet holes 111 are equal-diameter holes, and their hole diameter is 1 - 1.5 mm. The hole diameter of the water outlet holes 111 themselves determines the water flow rate and pressure. It has been verified that within the above range, it can meet the relatively comfortable shower needs of ordinary people. As a preferred implementation manner, the specific thickness of the water outlet plate 11 is 4 mm, the specific angle between the axis of the water outlet hole 111 and the vertical center line passing through the center of the water outlet plate 11 is 2°, and the specific hole diameter of the water outlet holes 111 is 1.2 mm.

[0032] Furthermore, each water outlet hole 111 is evenly distributed on a circumference with a diameter of 40 - 45 mm. By setting the water outlet holes 111 on a circumference within such a diameter range, and then combining with the thickness dimension of the above-mentioned water outlet plate 11, the inclination angle of the water outlet holes 111, and the hole diameter of the water outlet holes 111 themselves, a more specific and appropriate shower coverage range can be obtained, which can meet the shower needs of most people. As a preferred implementation manner, each water outlet hole 111 is evenly distributed on a circumference with a diameter of 42 mm, and the central angle between two adjacent water outlet holes 111 is 15°. Therefore, there are a total of 24 water outlet holes 111. The number of water outlet holes 111 is relatively reasonable. It is neither too many to affect the water outlet pressure and cause waste of water resources, nor too few to affect the bathing effect. At the same time, the central angle between adjacent water outlet holes 111 is an integer, which is convenient for processing and manufacturing.

[0033] Furthermore, the inner hole diameter of the annular cover body 12 is equal to the diameter of the water outlet plate 11. In fact, the axial length of the internal thread 121 is less than the length of the inner hole of the annular cover body 12. The inner hole of the annular cover body 12 also includes a smooth section, and the inner diameter of the smooth section is equal to the major diameter of the internal thread 121. The water outlet plate 11 is circular, and the diameter of the water outlet plate 11 is 55 - 60 mm. This range defines the volume of the water cavity communicated with the water outlet holes 111. It has been verified that below this range, the pressure of the sprayed water is moderate and very suitable for bathing. As a preferred embodiment, the diameter of the water outlet plate 11 is 58 mm.

[0034] As Figure 7 shown, the lower cover 1 further includes a cover edge 13 connected to the annular cover body 12 and protruding downward from the water outlet plate 11. Through the cover edge 13, it is convenient to place the lower cover 1 or the overhead shower on other objects, and the water outlet holes 111 can be elevated through the cover edge 13 to prevent impurities from entering the water outlet holes 111 and causing blockage. The height of the cover edge 13 is less than the height of the annular cover body 12 to avoid excessive increase in the weight and volume of the lower cover 1. Further, the entire lower cover 1 is injection molded. The outer peripheral dimensions of the annular cover body 12 and the cover edge 13 are equal. The inner hole of the cover edge 13 is a tapered hole with a gradually increasing aperture from top to bottom. The minimum aperture of the tapered hole is greater than the inner hole diameter of the annular cover body 12, so as not to affect the water outlet effect of the water outlet holes 111, and the average wall thickness of the cover edge 13 is relatively small to avoid excessive weight gain.

[0035] As Figure 8 and Figure 9 shown, the upper cover 3 includes a cylindrical section 31, an interface section 32, and a transition section 33 connected between the cylindrical section 31 and the interface section 32. The transition section 33 is conical. The interface section 32 is located at the top of the upper cover 3, and its outer diameter is smaller than the outer diameter of the cylindrical section 31. An inlet connection structure for connecting to a water pipe is provided on the interface section 32, and the inlet connection structure is communicated with the inner cavities of both the upper cover 3 and the lower cover 1.

[0036] Combined with Figure 5 shown, the inlet connection structure is specifically a ball joint 7. The ball joint 7 includes a hollow ball head and a connecting pipe. A filter screen 6 is arranged in the connecting pipe. The connecting pipe has internal threads for connecting to a water pipe. The ball head extends into the inner hole of the interface section 32, and a communication hole communicating with the inner hole of the upper cover 3 is provided on the ball head. A compression nut 5 is sleeved outside the ball head. The compression nut 5 has internal threads, and external threads are provided on the outer peripheral surface of the interface section 32. The compression nut 5 is threadedly connected to the interface section 32. By tightening the compression nut 5, the ball joint 7 can be fixed on the interface section 32. By loosening the compression nut 5, the relative angle between the ball joint 7 and the interface section 32 can be adjusted, so as to adjust the appropriate shower angle. In order to ensure the sealing of the ball joint 7 and prevent water from leaking outwards from the upper part of the overhead shower, as Figure 9As shown, a necking structure 321 is provided in the inner hole at the connection position between the interface section 32 and the transition section 33. The necking structure 321 forms a stepped surface 322. The gasket 4 is disposed on the stepped surface 322. The gasket 4 has a spherical surface adapted to the ball joint 7, and the ball head of the ball joint 7 presses against the spherical surface of the gasket 4.

[0037] As Figure 8 and Figure 9 shown, the cylindrical section 31 of the upper cover 3 is stepped and includes a large-diameter portion 311 and a small-diameter portion 312. The large-diameter portion 311 is connected to the transition section 33 and the outer diameter of the large-diameter portion 311 is equal to the outer diameter of the lower cover 1. An external thread adapted to the internal thread 121 on the inner wall of the lower cover 1 is provided on the small-diameter portion 312, which facilitates the connection and disassembly between the two. After the two are connected in place, the outer peripheral surface of the large-diameter portion 311 is aligned with the outer peripheral surface of the lower cover 1, which is relatively aesthetically pleasing and also convenient for packaging and transportation. A stepped surface 313 is formed between the large-diameter portion 311 and the small-diameter portion 312. To ensure the connection sealing performance between the upper cover 3 and the lower cover 1, as Figure 6 and Figure 7 shown, an installation groove 122 for installing the sealing ring 2 is provided on the upper end surface of the lower cover 1. After the upper cover 3 and the lower cover 1 are connected, the sealing ring 2 is squeezed and pressed against the stepped surface 313.

[0038] As Figure 5 and Figure 9 shown, except for the interface section 32, the inner hole of the upper cover 3 mainly includes a tapered hole 34 and a cylindrical hole 35. After water flows into the inner hole of the upper cover 3 from the ball joint 7, it directly flows to the water outlet hole 111 on the lower cover 1, that is, the water outlet hole 111 is directly communicated with the inner cavities of the upper cover 3 and the lower cover 1. No other components are provided in the inner holes of the upper cover 3 and the lower cover 1, eliminating components such as a water distribution body, a gland, and a spring in the prior art, reducing the number of components, simplifying the structure, reducing costs and failure rates, and also solving the problem of rusty water flowing out due to spring rust. At the same time, the entire overhead shower is a structure with a height-to-diameter ratio greater than 1. The total height after the upper cover 3 and the lower cover 1 are connected is greater than the outer diameter of the lower cover 1, with a small lateral dimension, ensuring the water outlet pressure and effectively improving the problem of water resource waste.

[0039] In other embodiments of the overhead shower: when there is only one circle of water outlet holes, the angle between the axis of each water outlet hole and the vertical center line passing through the center of the water outlet plate can also be 1.5° or 2.5°, and of course it can also be 1° or 3°.

[0040] In other embodiments of the overhead shower: The water outlet holes on the water outlet plate can be arranged in two circles, including the inner circle of water outlet holes and the outer circle of water outlet holes. The water outlet holes in the inner circle are straight holes extending vertically, and the water outlet holes in the outer circle are inclined holes. The angle between the outer circle of water outlet holes and the vertical center line passing through the center of the water outlet plate is 1.5 - 2.5°, specifically it can be 1.5°, 2° or 2.5°.

[0041] In other embodiments of the overhead shower: When there are two circles of water outlet holes on the water outlet plate, both circles of water outlet holes can be inclined holes, and the inclination angles are the same. Of course, the inclination angles can also be different. For example, the inclination angle of the inner circle of water outlet holes is less than that of the outer circle of water outlet holes.

[0042] In other embodiments of the overhead shower: The water outlet holes on the water outlet plate can also be arranged in three circles. At this time, the water outlet holes in the innermost circle can be set as straight holes extending vertically, and the water outlet holes in the outermost circle and the middle circle are inclined holes. And the inclination angles of the inclined holes can be the same. Of course, they can also be different. For example, the inclination angle of the water outlet holes in the middle circle is less than that of the water outlet holes in the outermost circle.

[0043] In other embodiments of the overhead shower: When there are three circles of water outlet holes on the water outlet plate, all three circles of water outlet holes can be inclined holes, and from the inside to the outside, the inclination angles of each circle of water outlet holes increase in turn.

[0044] In other embodiments of the overhead shower: The thickness of the water outlet plate can also be 3 mm or 5 mm. Of course, it can also be 3.5 mm, 4.5 mm, 5.5 mm or 2.8 mm.

[0045] In other embodiments of the overhead shower: When there is only one circle of water outlet holes, each water outlet hole can be arranged on a circumference with a diameter of 40 mm. Of course, the diameter can also be 41 mm, 43 mm, 44 mm, 45 mm, 46 mm or 39 mm; in other embodiments, the central angle between adjacent two water outlet holes can also be 12° or 18°. Of course, the central angle can also have a decimal, and according to the specific size of the water outlet plate, the central angle can be larger; in other embodiments, the aperture of the water outlet hole can also be 1 mm, 1.1 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm or 0.9 mm.

[0046] In other embodiments of the overhead shower: The inner hole of the lower cover edge can be an equal-diameter hole, and the diameter of the cover edge is less than the inner hole diameter of the annular cover body.

[0047] In other embodiments of the overhead shower: The lower cover can not include a cover edge. At this time, the end face of the water outlet hole is directly flush with the end face of the lower cover.

[0048] In other embodiments of the overhead shower: an installation groove may be provided on the stepped surface of the upper cover to install a sealing ring, and at this time, the sealing ring is in extrusion contact with the upper end surface of the lower cover.

[0049] In other embodiments of the overhead shower: the sealing ring may also be sleeved on the outer peripheral surface of the small-diameter part. At this time, the sealing ring is in sealing cooperation with the inner wall of the lower cover, and at this time, there is no need to provide an installation groove on the end surface of the lower cover or the stepped surface of the upper cover.

[0050] In other embodiments of the overhead shower: the outer diameter of the large-diameter part of the upper cover may also be greater than the outer diameter of the lower cover. At this time, after the upper cover and the lower cover are connected in place, the outer peripheral surface of the large-diameter part is not aligned with the outer peripheral surface of the lower cover.

[0051] In other embodiments of the overhead shower: the detachable connection method between the lower cover and the upper cover may not be internal and external threads, but flange connection. At this time, flanges are respectively provided at the edges of the lower cover and the upper cover, and bolts pass through the two flanges and are fixed with nuts.

[0052] In other embodiments of the overhead shower: the transition section may not be conical, but flat.
