Description

Technical Field

[0001] The invention relates to a water outlet device, in particular to a bathtub water outlet device. Background Art

[0002] When people are using a bathtub, they need to manually check the water level. If the bathtub water is turned on and the person leaves for a long time and forgets to check the water level and turn it off, there is a risk of the bathtub water overflowing, or the water level exceeds the user's required water level, resulting in water waste.

[0003] Most of the traditional bathtub shower systems on the market in North America have a structure where water enters the main control and is divided into upper and lower water outlets. The upper and lower water outlets are connected, and the bathtub faucet has a mechanical switch. When it is turned on, the water is discharged from the bathtub faucet due to continuous pressure relief, and the water will not be discharged from the upper water outlet. When it is closed, due to the internal pressure of the pipe, the water is rushed upward and discharged from the upper water outlet. Because of the simple and practical structure, the upper and lower water outlet switches are not set separately on the main control, but the upper and lower water outlets are directly controlled by adjusting the opening and closing of the lower water outlet. In the electronic quantitative system, in order to ensure the integrity, installation convenience, and compact structure of the electronic quantitative faucet, the solenoid valve is placed in the quantitative faucet. In addition to the manual on and off, there will also be a functional automatic disconnection. When the bathtub faucet of the existing traditional bathtub system is replaced with an electronic quantitative faucet, its solenoid valve will have a functional automatic disconnection, and the water path will go to other terminal water outlets for automatic switching, causing great inconvenience to the user.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-Figure 10 The present embodiment provides a bathtub water outlet device with quantitative water outlet, comprising: a top spray shower 1, a quantitative bathtub faucet 2 and a water outlet control component 3; the top spray shower 1 and the quantitative bathtub faucet 2 are connected to the upper water outlet and the lower water outlet of the water outlet control component 3 through an upper water outlet pipe 4 and a lower water outlet pipe 5 respectively;

[0033] The quantitative bathtub faucet 2 is provided with a water outlet control switch 21, a flow selection switch 22, a water outlet solenoid valve 23, a flow meter 24 and a control chip 25; the control chip 25 is arranged between the water outlet solenoid valve 23 and the lower water outlet pipe;

[0034] The flow selection switch 22 is linked to the encoder 221, and after the encoder is connected to the control chip 25, it has an unlimited water output gear and a plurality of quantitative water output gears;

[0035] The water outlet control switch 21 and the flow selection switch 22 are independently arranged. After the flow selection switch 22 drives the encoder to set a suitable water outlet gear, the water outlet control switch 21 is operated to make the control chip 25 open the water outlet solenoid valve 23 to make the quantitative bathtub faucet 2 discharge water; the flow meter 24 counts the water flow passing through the flow meter 24. When the water flow reaches the set value of the water outlet gear, the control chip 25 closes the water outlet solenoid valve 23 to stop the quantitative bathtub faucet 2 from water.

[0036] Specifically, the quantitative bathtub faucet 2 includes a faucet body, the front lower part of the faucet body is a water outlet, and the front upper part of the faucet body is an opening for installing a water outlet control switch 21 and a flow selection switch 22; a fixed seat 26 is arranged in the faucet body through the opening, and the fixed seat 26 has an opening for installing a connecting member 27, so that one end of the connecting member 27 is plugged and fixed to the fixed seat 26. The flow selection switch 22 is arranged on the outside of the fixed seat 26. In this embodiment, it is a knob, which is rotatably connected to the fixed seat 26 so that it can rotate relative to the fixed seat 26. The water outlet control switch 21 is arranged in the fixed seat 26, so that the water outlet control switch 21 and the flow selection switch 22 are independent. In this embodiment, the water outlet control switch 21 is a sensing component, and its upper surface is exposed at the opening, so that the user can touch the opening part to achieve touch control of water outlet.

[0037] The sensing component needs to be connected to the control chip 25 via a data line, so that after the sensing component receives the touch signal and sends it to the control chip 25, the control chip 25 can control the water outlet solenoid valve 23 to open and discharge water. Similarly, the encoder 221 is also set in the faucet body, and it is also connected to the control chip 25 via a data line, so as to send the gear information set by the user to the control chip.

[0038] In this embodiment, the upper surface of the knob is provided with a flow scale along the circumferential direction, and an indicator cover 28 is also fixedly connected to the upper surface of the fixing seat 26, and an indicator mark is provided on the indicator cover 28. When the user turns the knob, the flow scale rotates relative to the indicator mark, so that which scale on the flow scale the indicator mark finally aligns with represents the flow value set by the user.

[0039] In this embodiment, when the flow selection switch 22 is rotated to one side, the encoder 221 is rotated to the unlimited water outlet position; when the flow selection switch 22 is rotated to the other side, the encoder 221 is rotated to one of the plurality of quantitative water outlet positions. In this way, in addition to selecting a set flow rate, the user can also select an unlimited flow mode, which is similar to the use of a traditional bathtub faucet. This makes it convenient for users to choose whether to use quantitative water outlet.

[0040] In order to identify both the quantitative mode and the infinite mode, the flow scale has a scale corresponding to the infinite water outlet gear and a plurality of scales corresponding to the quantitative water outlet gear; when the knob is rotated so that the scale on the scale is aligned with the indicator mark, the currently selected water outlet flow rate can be indicated.

[0041] The water outlet solenoid valve 23 also needs to be installed in the faucet body. Specifically, a valve seat is provided at the water inlet end of the faucet body, and the water outlet solenoid valve 23 is installed on the valve seat. The flow meter 24 is installed between the water outlet solenoid valve 23 and the water inlet end of the faucet body. The flow meter also needs to be connected to the control chip 25 with a data line, so that the current amount of water flowing through the flow meter 24 is sent to the control chip 25. The control chip 25 compares the current flow that has flowed through the flow meter with the flow set by the user. Once the current flow reaches the flow value set by the user, the control chip 25 controls the water outlet solenoid valve 23 to close.

[0042] In this embodiment, the water inlet end of the faucet body is connected to the water pipe joint on the wall, and the connection between the two is covered by a flange cover. In addition to covering the connection, the flange cover forms a certain space between the flange cover and the wall, and this space can be used to install the control chip 25 and the power supply component 29; the power supply component 29 includes a battery box 291 and a battery holder 292, and the battery box 291 and the battery holder 292 are detachably connected by a connecting mechanism 293.

[0043] Specifically, the connecting mechanism 293 includes a ballpoint pen pressing mechanism 2931, a push block 2932, an elastic buckle 2933 and a battery holder buckle 2934; the push block 2932 is arranged in linkage with the ballpoint pen pressing mechanism 2931, and the elastic buckle 2933 is covered on the outside of the push block 2932; the end of the elastic buckle 2933 away from the push block 2932 is an elastic end, and its width along the direction perpendicular to the movement of the push block 2932 is smaller than the width of the push block 2932; the distance of the elastic end along the moving direction of the push block is smaller than the maximum displacement of the push block 2932 driven by the ballpoint pen pressing mechanism 2931.

[0044] In this embodiment, in order to operate the ballpoint pen pressing mechanism 2931, the battery box 291 further includes a button 2911 for driving the ballpoint pen pressing mechanism. Specifically, the button 2911 is arranged at the front end of the battery box 291 and exposed outside the battery holder 292, so as to facilitate user operation. An elastic rib 2912 is arranged on the side of the battery box 291 facing the button; a limiting surface 2913 is arranged on the side of the button 2911 facing the battery box 291, which abuts against the elastic rib 2912 along the pressing direction;

[0045] With the above arrangement, when the battery box 291 is not pressed and the elastic buckle 2933 has not entered the cavity surrounded by the battery seat buckle 2934, the end surface of the elastic rib 2912 and the limiting surface 2913 on the button 2911 are pressed against each other along the pressing direction to limit the position, so that the button 2911 of the ballpoint pen structure cannot be pressed.

[0046] When the battery box 291 is pressed, the protrusion 2914 is pressed against the step slope 2921, so that the elastic rib 2912 is retracted inward, and the elastic end of the elastic buckle 2933 enters the cavity surrounded by the battery seat buckle 2934. At this time, the button 2911 is released from the limit because the end of the elastic rib 2912 leaves the limit surface 2913, and the button 2911 can be pressed normally.

[0047] When the ballpoint pen pressing mechanism 2931 moves from the initial position to the downward pressing position, the push block 2932 is pushed by the ballpoint pen pressing mechanism 2931 to move downward to the lowest position. At this time, the push block 2932 first moves downward relative to the elastic buckle 2933. Since the width of the push block 2932 is greater than the width between the elastic ends, the push block 2932 will be squeezed with the elastic end during the downward movement, driving the elastic end of the elastic buckle 2933 to expand outward, so that the maximum width of the talk-type buckle 2933 is greater than the minimum width of the battery holder buckle 2934. After the ballpoint pen mechanism 2931 moves to the lowest position and is released, it will rebound a short distance. At this time, the push block 2932 moves upward under the action of the spring, and the maximum width of the elastic buckle 2933 is still larger than the minimum width of the battery seat buckle 2934. The battery box 391 receives the upward force of the battery spring on the battery seat, driving the elastic buckle 2933 to move upward a certain distance, so that the flat parts of the elastic buckle 2933 and the battery seat buckle 2934 press against each other, and are limited in the upward direction, and the battery box 291 is fixedly connected to the battery seat 292.

[0048] If you want to take out the battery box 291, you only need to operate the ballpoint pen pressing mechanism 2931 to reset it.

[0049] In addition, after the battery box 291 is taken out, the elastic buckle 2933 is in a non-expanded and deformed state, which prevents the battery seat buckle 2934 from being blocked by the elastic buckle 2933, causing the battery box to be unable to be installed.

[0050] The battery seat 292 has a cavity for accommodating the battery box 291, and one end of the cavity is an open surface; the side wall of the cavity at the open surface has a stepped inclined surface 2921 along the pressing direction, which is used to shrink the width of the open surface; the outer wall of the elastic rib 2912 has a protrusion 2914;

[0051] Finally, in this embodiment, the water outlet control assembly 3 includes a main control handle 31 and a top spray water outlet switch 32;

[0052] When the main control handle 31 is turned on, the water flows all the way to the lower water outlet pipe 5 and all the way to the top water outlet switch 32; when the main control handle 31 and the top water outlet switch 32 are turned on at the same time, the water flows all the way to the lower water outlet pipe 5 and all the way to the upper water outlet pipe 4 through the top water outlet switch. In this embodiment, the water outlet control component 3 has an operation panel, and the main control handle 31 and the top water outlet switch 32 are both set on the operation panel. As a simple replacement, the top water outlet switch 32 can also be set in other positions, which belongs to the simple replacement of this embodiment.

[0053] The above is only a preferred embodiment of the present invention and cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still fall within the scope of the present invention.
