Detailed Description

The technical solutions herein are further described below by means of specific embodiments in combination with the accompanying drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to be limiting.

In one embodiment of the present application, as shown in fig. 1 to 25, a spray head is provided, which is applied to a toilet to assist the toilet in discharging sewage. As shown in fig. 1 to 6, the jet head is mounted at the jet port 101 of the toilet body 1. The toilet body 1 may be made of ceramic material, plastic material, or the like.

The spray head comprises a body 2 and an adapter 3 sleeved on the outer wall of the body 2. The body 2 may be provided as a cylinder as shown in fig. 11 and 12. The adapter 3 is rotatable about the central axis of the body 2. The adapter 3 is fitted behind the body 2 as shown in fig. 3 and 6. The body 2 is provided with a first waterway 201 and a second waterway 202, and a first water inlet 201a and a first water outlet 201b communicating with the first waterway 201, and a second water inlet 202a and a second water outlet 202b communicating with the second waterway 202, as shown in fig. 11 and 12. As shown in fig. 1 and fig. 4, the first water outlet 201b and the second water outlet 202b are both disposed towards the water inlet of the siphon elbow in the toilet, so that a better flushing effect can be obtained by flushing the first water path 201 or the second water path 202. Wherein, the flow areas of the first water outlet 201b and the second water outlet 202b are different.

The adaptor 3 has a flow path 301 and an inlet 301a and an outlet 301b communicating with the flow path 301. The inlet 301a may be provided in a circular shape or the like, and may be used to externally connect a water pipe to supply water to the spray head. The adapter 3 may communicate with one of the first waterway 201 and the second waterway 202. In the embodiment of the present application, the description of the technical solution is given by taking the communication between the adapter 3 and the first waterway 201 as an example. The outlet 301b of the adapter 3 communicates with the first water inlet 201a as shown in fig. 2.

The spray head provided in this embodiment of the application has two waterways, namely a first waterway 201 and a second waterway 202, and the flow areas of the water outlets of the two waterways are different, so that the closestool provided with the spray head can adapt to various use scenes, for example, when the water supply pressure is large, the waterway with the large flow area of the water outlet can be selected for water supply, the flushing noise can be effectively reduced, and the excellent flushing effect can be obtained. When the water supply pressure is smaller, the waterway with smaller flow area of the water outlet can be selected for water supply, so that a better scouring effect is obtained, and basically the same scouring effect can be ensured under different water supply pressures. Or, two waterways can be selected to supply water simultaneously so as to meet the use requirements of different users. Furthermore, by means of the relative adjustability of the adapter 3 and the body 2, the adjustability of the inlet 301a can be achieved, so as to improve the adjustment flexibility of the jet head, adapt to different toilet arrangements and improve the practicability of the jet head. It will be appreciated by those skilled in the art that the external water source is in communication with the second water inlet 202a and the inlet 301a of the spray head for supplying water to the toilet bowl.

In some exemplary embodiments, as shown in fig. 2 and 5, a water passing groove 4 is provided between the adapter 3 and the body 2. The outlet 301b of the adapter 3 communicates with the first water inlet 201a via the water trough 4. As shown in fig. 2 and 5, the flushing water enters the flow path 301 from the inlet 301a, enters the water passing tank 4 through the outlet 301b, flows into the first water inlet 201a, passes through the first water path 201, and is discharged from the first water outlet 201 b. The water passing groove 4 may be circumferentially provided around the body 2. Depending on the design of the rotation angle range of the adapter 3 relative to the body 2, the water passing groove 4 can encircle a part of the circumference of the body 2 or encircle the body 2.

In some exemplary embodiments, as shown in fig. 2, one of the adapter 3 and the body 2 is provided with an annular groove to enclose an annular water passing groove 4 with the other of the adapter 3 and the body 2. For example, an annular groove may be provided on the adapter 3 to enclose an annular water passing groove 4 with the outer wall of the body 2. Or, an annular groove is arranged on the body 2 so as to enclose an annular water passing groove 4 with the inner wall of the adapter 3. Or, the outer wall of the body 2 and the inner wall of the adapter 3 are respectively provided with an annular groove, and the two annular grooves jointly enclose an annular water passing groove 4. The depth of the water passing groove 4 along the circumferential direction of the body 2 may be designed to be constant as shown in fig. 2, or sequentially designed to be gradually increased as shown in fig. 5, or the like.

In some exemplary embodiments, as shown in fig. 15 and 16, the adapter 3 may be configured to include an annular socket portion 302 and an outwardly extending extension portion 303. The socket 302 and the extension 303 may be integrally formed, such as by casting or injection molding. The socket 302 is sleeved on the outer wall of the body 2, and the extension 303 extends in the radial direction of the body 2 in a direction away from the central axis of the body 2. The angle between the central axis of the extension 303 and the central axis of the socket 302 may be designed as an acute angle or as an obtuse angle. The inlet 301a may be provided at an end of the extension 303 remote from the body 2. The region of the extension 303 penetrating the inner wall of the socket 302 is provided with an outlet 301b.

In some exemplary embodiments, as shown in fig. 16, the outer wall of the sleeve portion 302 may be designed differently, and a partial area of the outer wall of the sleeve portion 302 may be designed to be thinned, so as to reduce the overall weight of the injector head and reduce the production cost of the product.

In some exemplary embodiments, as shown in fig. 3, the outlet 301b is located at the middle of the water passing groove 4 in the axial direction of the body 2, i.e., in the left-right direction, and the outlet 301b is not located at the end of the water passing groove 4. On the one hand, the assembly precision requirement of the adapter 3 and the body 2 can be reduced, the requirement on the precision of the limiting structure can be reduced, the assembly cost can be reduced, and on the other hand, the arrangement of the sealing structure between the adapter 3 and the body 2 is facilitated, so that the overall sealing performance of the injection head is improved.

In some exemplary embodiments, as shown in fig. 13 and 14, at least a portion of the bottom of the water tub 4 may be inclined to form the guide wall 401. For example, the bottom of the water passing tank 4 is all inclined, or the bottom of the water passing tank 4 is inclined in a region near the first water inlet 201 a. The flow is guided in the direction of the first water outlet 201b by the guide wall 401, as shown in fig. 2 and 5. The flow guide wall 401 can make the flushing water smoothly flow from the water trough 4 to the first waterway 201 and the second waterway 202, so as to obtain better flushing capability.

In some exemplary embodiments, as shown in fig. 13 and 14, the guide wall 401 may be configured as an inclined straight surface, or the guide wall 401 may be configured as an arc surface, so as to adapt to the requirements of different waterway flow areas, so as to improve the flow performance of the fluid.

In some exemplary embodiments, as shown in fig. 2, 5, 13, and 14, a channel and a separation rib 203 disposed in the channel are disposed in the body 2. Dividing rib 203 is used to divide the channel into first waterway 201 and second waterway 202. The dividing rib 203 may be provided in a circular arc shape or in a wave shape or the like along a contour line perpendicular to the central axis direction of the body 2 so that the flushing water obtains good fluidity and the products of the spray head have variety.

As shown in fig. 13, separator rib 203 can include a first segment 203a and a second segment 203b that meet smoothly. Alternatively, as shown in fig. 5 and 14, separator rib 203 includes a first segment 203a, a second segment 203b, and a third segment 203c that meet smoothly. The partition rib 203 can be shared with the water passing groove 4 to simplify the design structure of the jet head and reduce the weight of the whole product. The second section 203b of the separator rib 203 may be used as the guide wall 401.

In some exemplary embodiments, as shown in fig. 2 and 5, the flow area of the first waterway 201 is designed to be a constant value, and the flow area of the first waterway 201 may be the same as the flow area of the first water outlet 201 b. Alternatively, the flow area of the first water channel 201 is designed to be variable in cross section along the axial direction of the first water channel 201, and the flow area of the region of the first water channel 201 near the first water outlet 201b is the same as the flow area of the first water outlet 201 b. Alternatively, the flow area of the first waterway 201 gradually decreases toward the first water outlet 201 b. Alternatively, the flow area of the first water path 201 gradually increases toward the first water outlet 201 b. The flow area of the first waterway 201 is designed by referring to the flow area of the first water outlet 201b, so that abrupt change of the flow area of the first waterway 201 can be avoided, and energy loss of flushing water in the flowing process can be reduced, so that a better flushing effect can be obtained. The flow area of the second water path 202 may be designed with reference to the flow area of the first water path 201, i.e., the flow area of the second water path 202 may be designed to be the same as the flow area of the second water outlet 202b, or the flow area of the second water path 202 in the area near the second water outlet 202b may be designed to be the same as the flow area of the second water outlet 202 b.

In some exemplary embodiments, as shown in fig. 2 and 5, in the structure in which the flow area of the first water outlet 201b is smaller than the flow area of the second water outlet 202b, the minimum flow area of the second water path 202 is set in the range of 86.5 square millimeters to 133.0 square millimeters, and the minimum flow area of the first water path 201 is set in the range of 16.0 square millimeters to 35.0 square millimeters. In the structure in which the flow area of the first water outlet 201b is larger than the flow area of the second water outlet 202b, the minimum flow area of the first water path 201 is set in the range of 86.5 square millimeters to 133.0 square millimeters, and the minimum flow area of the second water path 202 is set in the range of 16.0 square millimeters to 35.0 square millimeters. The flow area is set in the range of 86.5 to 133.0 square millimeters and the equivalent circle diameter is in the range of 10.0 to 13.0 millimeters. The flow area is set in the range of 16.0 square millimeters to 35.0 square millimeters and the equivalent circle diameter is in the range of 4.5 millimeters to 6.7 millimeters.

Influencing the spray effect of the spray head in addition to the flow area of the first water outlet 201b and the second water outlet 202b, there is also the effective length of the first water channel 201 and the second water channel 202. The ratio of the effective length of the waterway to the equivalent circular diameter of the flow area of the water outlet is the length-diameter ratio. As shown in fig. 13, 14, and 20, the effective length is a region length in which the flow area of the water channel along the axial direction of the jet head is equal to the flow area of the water outlet, the effective length of the first water channel 201 is denoted as L1, and the effective length of the second water channel 202 is denoted as L2. As shown in fig. 21, the equivalent circle diameter of the flow area of the first water outlet 201b is denoted as D1, and the equivalent circle diameter of the flow area of the second water outlet 202b is denoted as D2. The aspect ratio may be set in a range of between 3.5 and 5.5. When the length-diameter ratio is less than 3.5, the problems of spray water spray divergence and poor scouring function are caused. When the length-diameter ratio is greater than 5.5, serious flow restriction and pressure loss are caused, and the flushing function is also affected.

The larger one of the first water outlet 201b and the second water outlet 202b has a shape as close to a circle, for example, a circle or a large semicircle, so as to control the water jet not to diverge, so that the low-speed water jet still has a certain thrust, the toilet is smoothly siphoned, and dirt in the toilet is taken away. In addition, because the water-saving type toilet is in a high-flow use state, more water in the toilet always covers the sewage inlet of the toilet, and the sewage replacement effect and the sewage discharge performance in various flushing states can be ensured. The smaller flow area of the first water outlet 201b and the second water outlet 202b is in a jetting state with high flow velocity and low flow, and if the jetting water column is in a relatively regular converging state, the problem of incomplete sewage replacement and possible residual sewage is generated, so that the smaller flow area of the first water outlet 201b and the second water outlet 202b needs to be in a slightly divergent jetting effect through the special shape of the outline, for example, the jetting device can be set to be crescent-shaped, so that when the smaller flow area of the first water outlet 201b and the second water outlet 202b is used for jetting, more positions can be cleaned, and residual water is taken away completely, thereby realizing a complete sewage replacement effect and better sewage discharging performance.

In another embodiment of the present application, as shown in fig. 1, 4 and 22, a toilet is provided. The toilet includes a toilet body 1 provided with an injection port 101, and an injection head according to any of the above embodiments. Wherein the jet head is installed at the jet port 101, and the smaller one of the first water outlet 201b and the second water outlet 202b is closer to the bottom of the toilet body 1, that is, closer to the ground.

As shown in fig. 22, the toilet body 1 is provided with a pipe hole 102. The via hole 102 may be a circular hole or the like. Depending on the type of toilet, the pipe passing hole 102 may be provided in any area of A, B, C, D identified in the figure, and the angle of the adaptor 3 of the jet head relative to the body 2 may be adaptively adjusted according to the position of A, B, C, D, for example, as shown in fig. 23 to 25, fig. 23 is a schematic view of a partial cross section of the pipe passing hole 102 in the D area toilet in fig. 22, fig. 24 is a schematic view of a partial cross section of the pipe passing hole 102 in the B area toilet in fig. 22, and fig. 25 is a schematic view of a partial cross section of the pipe passing hole 102 in the C area toilet in fig. 22. By utilizing the jet head provided by the embodiment of the application, the jet head can be suitable for different toilet structures, different pipeline wiring can be handled, higher adjustment flexibility and adaptability are realized, and the toilet provided with the jet head has higher use convenience.

In some exemplary embodiments, the toilet bowl further includes a first water supply assembly (not shown) and a second water supply assembly (not shown). For example, the first water supply assembly may be configured to include a booster pump or the like, which may provide a relatively large water supply pressure to the spray head, and the booster pump may be in communication with the water tank of the toilet bowl through a water pipe. The second water supply assembly may be configured to supply water from tap water with a lower water supply pressure than the first water supply assembly. Alternatively, the first water supply assembly may be configured to supply water from tap water, and the second water supply assembly may be configured to include a booster pump or the like. Alternatively, the first water supply assembly and the second water supply assembly have the same water supply pressure. The water supply pressure of the first water supply assembly and the water supply pressure of the second water supply assembly are designed in a differentiated mode, intelligent design of the closestool can be achieved, different use scenes can be dealt with, and different use environments are met.

The first water supply unit is configured to supply water to one of the first water outlet 201b and the second water outlet 202b having a larger flow area, and the second water supply unit is configured to supply water to one of the first water outlet 201b and the second water outlet 202b having a relatively smaller flow area. That is, the component that supplies water to one of the first water outlet 201b and the second water outlet 202b having a larger flow area is referred to as a first water supply component, and the other is referred to as a second water supply component. For example, the flow area of the first water outlet 201b is larger than the flow area of the second water outlet 202b, the first water supply assembly communicates with the inlet 301a, and flush water is supplied from the first water outlet 201b to the toilet body 1 via the first waterway 201. The second water supply assembly communicates with the second water inlet 202a, and flush water is supplied from the second water outlet 202b to the toilet body 1 via the second waterway 202. The water supply pressure of the first water supply assembly may be set to be greater than that of the second water supply assembly, and the water supply may be performed toward the one of the first water outlet 201b and the second water outlet 202b having the greater flow area by using the first water supply assembly having the relatively greater water supply pressure, so that the spray flushing effect may be enhanced, and the flushing noise may be reduced. The second water supply assembly with relatively smaller water supply pressure is used for supplying water to one of the first water outlet 201b and the second water outlet 202b with smaller flow area, so that the spraying speed can be improved, the flushing effect basically same as that obtained by supplying water from the first water supply assembly is obtained, and the consistency of the multiple flushing effects is ensured.

In some exemplary embodiments, the toilet bowl further includes a controller (not shown), and a control valve (not shown) electrically connected to the controller. The controller is pre-stored with a control program. The controller may be mounted on a component constituting the toilet bowl, or on a wall surface near the toilet bowl, etc. The control valve can be a one-way valve with simple structure, or a three-way valve, etc. Wherein the control valve is provided to be operable under the control of the controller to supply water to the toilet body 1 by the first water supply assembly, or to supply water to the toilet body 1 by the second water supply assembly, or to supply water to the toilet body 1 by both the first water supply assembly and the second water supply assembly. According to the actual use condition of the toilet, the control program in the controller can be set, for example, the first water supply assembly supplies water to the toilet body 1 in a default state, the second water supply assembly supplies water to the toilet body 1 in a manual selection mode, and the first water supply assembly and the second water supply assembly supply water to the toilet body 1 jointly in a manual selection mode.

In some exemplary embodiments, in a structure in which the first water supply assembly includes a booster pump in communication with the toilet tank and the second water supply assembly includes a water supply pipe for communication with tap water, automatic switching of the water supply state may be achieved using a detection unit (not shown) and a standby power supply (not shown). The detection unit is electrically connected with the controller and is used for detecting the pressure on the pipeline. The backup power supply is electrically connected with the controller to provide the energy source for the action of the control valve.

Wherein the detection unit is configured to detect the voltage at the input of the booster pump and send the detected voltage to the controller. When the controller judges that the voltage at the input end of the booster pump is smaller than the working voltage of the booster pump in normal operation, for example, power failure or low voltage, the controller controls the standby power supply to control the control valve, and the second water supply assembly supplies water to the toilet body 1. When the controller judges that the voltage of the input end of the booster pump is not less than the working voltage, the controller can shield the control of the standby power supply, namely, the standby power supply is not started, and the first water supply assembly supplies water to the toilet body 1 through the control of the control valve by the controller.
