Description

Technical Field

[0001] The present invention relates to the field of inductive drainage devices, and in particular, to a drainage device and a washbasin. Background Art

[0002] In the prior art, push-button or flip-type switches are installed at the drain outlets of bathtubs, washbasins, etc., which can switch the drain outlet to the closed state for water storage or to the open state for drainage. However, whether it is a push-button or flip-type switch, when performing the drainage operation, it is necessary to put the hand into the water to open the switch, which is likely to contaminate the washed hands again and requires re-washing.

[0003] In the related art, an inductive drainage device is used to control the opening or closing of the drain outlet, and the operations of drainage or water storage can be realized by recognizing the gestures of the user without directly touching the switch with the hand. The drainage device is installed on the tabletop and communicated with the drain outlet. Since the switch structure of the drainage device is located inside the drainage device and cannot be seen by the user, the user cannot intuitively judge whether the current washbasin is in the water storage state or the drainage state, and it is necessary to perform a water discharge test to know, which makes the user's washing steps cumbersome and affects the user experience. In addition, in order to prevent the washbasin from overflowing, it is necessary to open an overflow port on the side wall of the washbasin, which is relatively unsightly and requires an external overflow pipe, which is not conducive to the simplified design of the product. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a drainage device that can reflect the opening and closing of the water passage in the housing through the relative position relationship between the top cover and the housing, which is relatively intuitive, and can achieve the effect of preventing water overflow through the overflow channel inside the drainage device.

[0005] The present invention also provides a washbasin having the above drainage device.

[0045] Generally, the drain outlet of a common washbasin is located at the bottom of the basin body to facilitate the discharge of sewage. Therefore, a push-button drain device or a flip-up drain device is often provided at the bottom of the basin body 400. However, if the inductive drain device is installed at the bottom of the basin body 400, the sensor cannot sensitively sense the action signal shown by the user due to the influence of the water body. Moreover, there are many electronic control components in the inductive drain device, and there is a great risk of water seepage and leakage if it is installed at the bottom of the basin body 400. Therefore, the inductive drain device is generally installed on one side of the basin body 400 and communicated with the drain outlet 410 on the side wall of the basin body 400 (refer to Figure 1 shown). However, since the switch structure of the inductive drain device is inside the housing 100 of the drain device, it is often impossible to directly see the state of the drain outlet 410 in the current state. Therefore, it gives the user a sense of uncertainty, and it is necessary to conduct a water discharge test to know the state of the drain outlet 410, which is rather troublesome.

[0046] To solve the above problems, an embodiment of the first aspect of the present application proposes a drain device. Refer to Figures 1 to 6 shown, the drain device includes a housing 100 and a valve core 200. The housing 100 defines a water passage 110, and the water passage 110 runs through the housing 100 in the vertical direction. The housing 100 also defines a water inlet 120 on the side wall of the water passage 110 and a water outlet 130 at the lower end of the water passage 110. The valve core 200 is inserted into the water passage 110. The valve core 200 includes a top cover 210, a fixing member 220, a water sealing member 230, and a driving member 240. The fixing member 220 defines a first accommodating cavity for accommodating an inductive component for sensing, an electronic control component, a driving member 240 for driving, etc. The fixing member 220 abuts against the housing 100. The first accommodating cavity has an open mouth, and the top cover 210 closes the open mouth and is movably connected to the fixing member 220, such as Figure 6As shown, a connecting portion extends downward from the outer peripheral edge of the top cover 210 and can be inserted into the first accommodating cavity. Thus, whether the top cover 210 moves downward or upward, the top cover 210 can play a role in closing the open mouth, and can reduce the probability of water entering the first accommodating cavity from the open mouth. As Figure 3 and Figure 4 shown, Figure 3 is a schematic diagram of the water sealing member 230 in the first position, Figure 4 is a schematic diagram of the water sealing member 230 in the second position. Whether in the structure shown in Figure 3 or the structure shown in Figure 4 the top cover 210 can close the open mouth of the first accommodating cavity.

[0047] One end of the water sealing member 230 is provided to pass through the fixing member 220 and is respectively connected to the top cover 210 and the driving member 240. The other end of the water sealing member 230 is provided with a sealing portion 233, and the sealing portion 233 can close the water passing channel 110. In Figure 6 the shown embodiment, the end of the water sealing member 230 is provided with a first connecting portion 231 and a second connecting portion 232. A through groove 224 (as shown in Figure 11 ) is provided on the bottom wall of the fixing member 220. The first connecting portion 231 and the second connecting portion 232 can be respectively inserted into the first accommodating cavity through the corresponding through grooves 224. The top cover 210 further includes a third connecting portion 214 extending downward. The first connecting portion 231 and the third connecting portion 214 can be connected by a detachable connection method such as plug connection, snap connection or threaded connection. In Figure 6 the first connecting portion 231 can be snapped into the snap groove on the third connecting portion 214, thereby realizing the synchronous movement of the water sealing member 230 and the top cover 210. Referring to Figures 6 to 8 shown, the second connecting portion 232 extends into the first accommodating cavity and is connected to the driving shaft of the driving member 240 in the first accommodating cavity. The driving shaft of the driving member 240 can extend or retract relative to the main body portion of the driving member 240, and thus can drive the water sealing member 230 to move to the first position and the second position. The driving member 240 can be a motor as shown in Figure 7 or other driving mechanisms such as an air pump or a hydraulic pump.

[0048] As Figure 3 and Figure 4As shown, when the water seal member 230 and the top cover 210 move to the first position, the water seal member 230 opens the water outlet 130, and the sewage in the washbasin can be discharged through the water outlet 410 and the water passage 110, and the top cover 210 extends out of the housing 100. When in the second position, the water seal member 230 closes the water outlet 130, and thus the washbasin is in a water storage state. Due to the linkage effect of the top cover 210 and the water seal member 230, the top cover 210 retracts into the housing 100. Furthermore, the relative position relationship between the top cover 210 and the housing 100 reflects the opening and closing conditions of the water passage 110 in the housing 100 of the drainage device, which is relatively clear and obvious. When using the washbasin, the user can judge whether the current washbasin is in a drainage state or a water storage state by whether the top cover 210 protrudes from the housing 100, and thus can directly perform the washing operation or the action indication of state switching, without having to test the state of the current washbasin by draining water, and can also reduce the waste of water resources.

[0049] The water inlet 120 and the water outlet 130 are defined on the housing 100, as Figure 3 and Figure 4 shown, the water inlet 120 is located on the side wall of the water passage 110, and the water outlet 130 is located at the lower end of the water passage 110. There are two specific implementation manners for the water seal member 230 to open or close the water outlet 130 by moving in the vertical direction:

[0050] 1. As Figure 4 shown, the water passage 110 includes a water drainage section 111 and a water overflow section 112 arranged in sequence in the vertical direction. The water drainage section 111 is located below the water inlet 120 and is communicated with the water outlet 130. The inner diameter of the water drainage section 111 is smaller than that of the water overflow section 112. Thus, the sealing portion 233 of the water seal member 230 can move from the water overflow section 112 to abut against the inner wall of the water drainage section 111, that is, move in the direction from top to bottom to close the water outlet 130.

[0051] 2. The structural schematic diagram of this implementation manner is not shown in the figure, and reference can be made to Figure 4 shown, the water passage 110 includes a water drainage section 111 communicated with the water outlet 130. The water drainage section 111 is located below the water inlet 120. Along the direction from top to bottom, the inner diameter of the water drainage section 111 gradually increases. The sealing portion 233 of the water seal member 230 can move in the direction from bottom to top to abut against the water drainage section 111 to close the water outlet 130.

[0052] The sealing portion 233 can be as Figure 3 and Figure 4The shown sealing rubber ring has an outer diameter larger than the inner diameter of the water discharge section 111. Thus, when the sealing rubber ring moves into the water discharge section 111, it can undergo elastic deformation to fit against the inner wall of the water discharge section 111, thereby achieving the sealing effect on the water passage 110. The sealing part 233 can also be a conical sealing plug. The inner diameter of the water discharge section 111 gradually increases or decreases, and correspondingly, the outer diameter of the sealing plug gradually increases or decreases. The sealing plug can move from the large end to the small end direction of the water discharge section 111 to abut against the inner wall of the water discharge section 111, thus completing the sealing operation. The sealing part 233 can also be provided with a sealing rubber ring on any end face in the up and down direction. There is a section with a sharp increase or decrease in the inner diameter between the water discharge section 111 and the water overflow section 112. Furthermore, the end face of the sealing part 233 can abut against the end face of the water discharge section 111 to complete the sealing operation.

[0053] In addition, it should be noted that, as Figure 4 shown, the arrow direction in the figure indicates the moving direction of the water flow. An overflow channel 234 running through in the vertical direction is defined inside the water sealing member 230. A first communication part 235 communicating with the water passage 110 is provided at the upper end of the overflow channel 234, and a second communication part 236 communicating with the water outlet 130 is provided at the lower end of the overflow channel 234. The second communication part 236 is located below the sealing part 233. When the water sealing member 230 is in the second position, the water inlet 120 is communicated with the water outlet 130 through the overflow channel 234. When the water sealing member 230 is in the second position, the original drainage path (i.e., discharging from the water inlet 120 through the water discharge section 111 and out from the water outlet 130) is closed by the sealing part 233, and the water cannot be discharged, so it accumulates in the washbasin. The water level in the washbasin continues to rise, the water submerges the water inlet 120, and continues to accumulate. The water level in the water pipe is kept consistent with the water level in the washbasin. When the water rises to the position of the first communication part 235, the water flows from the first communication part 235 into the overflow channel 234 and is discharged to the water outlet 130 through the second communication part 236, thus ensuring that the water level in the washbasin will not exceed the horizontal height of the first communication part 235 to prevent the water in the washbasin from overflowing and causing waterlogging on the ground.

[0054] Among them, referring to Figure 6 shown, one end of the water sealing member 230 is provided with a first connection part 231 passing through the fixing member 220 and connected to the top cover 210 and a second connection part 232 passing through the fixing member 220 and connected to the driving member 240. The first connection part 231 and the second connection part 232 extend along the axial direction of the water sealing member 230, and a first communication part 235 is defined between the first connection part 231 and the second connection part 232. The number of the first connection part 231 and the second connection part 232 can be adjusted according to the actual situation. As Figure 6In the illustrated embodiment, the water sealing member 230 is provided with two first connecting portions 231 evenly distributed in the circumferential direction and a second connecting portion 232 disposed between the two first connecting portions 231. A first communicating portion 235 is defined between the first connecting portion 231 and the second connecting portion 232, and a third communicating portion communicating with the water passage 110 is further defined between the two first connecting portions 231.

[0055] As Figure 7 and Figure 8 shown, the valve core 200 further includes a first elastic member 250. The first elastic member 250 is disposed in the first accommodating cavity. Two ends of the first elastic member 250 are respectively connected to the top cover 210 and the fixing member 220. When the water sealing member 230 is in the second position, the first elastic member 250 is in a compressed state. Since the first elastic member 250 has a tendency to recover its elastic deformation, an upward elastic force is applied to the top cover 210. The upward elastic force of the top cover 210 is transmitted to the water sealing member 230 through the first connecting portion 231, so that the water sealing member 230 has an upward pre-tightening force. When the user shows a gesture to open the water passage 110 for draining water, the sensing chip 270 recognizes the gesture and issues an instruction to operate the driving member 240. The driving member 240 drives the water sealing member 230 to switch from the second position to the first position. When the driving member 240 operates, since there is an upward pre-tightening force on the water sealing member 230, the driving member 240 can drive the upward movement of the water sealing member 230 with a smaller driving force. When the water sealing member 230 switches from the first position to the second position, the driving member 240 drives the water sealing member 230 to move downward, and the first elastic member 250 is compressed. Since each component such as the water sealing member 230 and the top cover 210 has a certain gravity, the downward gravity of each component will offset a part of the upward elastic force of the first elastic member 250, so that it can move downward more easily and smoothly. Based on the foregoing, through the setting of the first elastic member 250, a motor with a smaller torque can be used to drive a larger load.

[0056] As Figure 8 and Figure 9 shown, the valve core 200 further includes a flip cover 260. A rotating shaft is provided on the bottom surface of the flip cover 260. A groove for accommodating the rotating shaft and a limiting groove 211 provided on the side wall of the groove are provided on the top surface of the top cover 210. Two ends of the rotating shaft are inserted into the limiting groove 211 to realize the rotational connection between the flip cover 260 and the top cover 210. An avoidance portion 212 is further provided on the top cover 210. As Figure 8 and Figure 9 shown, the avoidance portion 212 is an inclined surface, so that when the flip cover 260 rotates relative to the top cover 210, a part extends obliquely upward to protrude from the top cover 210, and a part extends obliquely downward and is accommodated in the avoidance portion 212. Correspondingly, as Figure 6As shown, the fixing member 220 also has a corresponding avoidance structure to avoid interfering with the rotation of the flip cover 260. The second elastic member 213 is also connected to the rotating shaft of the flip cover 260. The second elastic member 213 has a tendency to restore the flip cover 260 to a close fit with the top cover 210. When the user presses the flip cover 260 to flip it, when the user no longer applies pressure, the second elastic member 213 can drive the flip cover 260 to return to a horizontal state. Specifically, the second elastic member 213 can be a torsion spring, and the elastic force of the torsion spring on the flip cover 260 is upward and forward, which can keep the flip cover 260 and the top cover 210 close to each other without tilting.

[0057] Based on the above, when the valve core 200 of the water discharge device fails, the flap 260 is pressed to partially lift up the flap 260, thereby providing a force application location for the user. The user can lift the flap 260 to drive the valve core 200 to separate from the shell 100 as a whole, which greatly facilitates the maintenance and replacement of the valve core 200.

[0058] like Figure 8 As shown, the valve core 200 also includes a sensor chip 270, which can identify the user's actions and then transmit an electrical signal to the driving member 240 to control the operation of the driving member 240 and then control the water sealing member 230 to open or close the water passage 110. In order to achieve the integration of the device, the sensor chip 270 is set on the top cover 210, as shown in FIG. Figure 8 As shown, the top cover 210 is provided with a through slot for exposing the sensing chip 270, and the flip cover 260 is also provided with a through slot for exposing the sensing chip 270. In other embodiments, the sensing chip 270 may also be provided on the top surface of the top cover 210, and connected to the driving member 240, the processing chip and other electronic control components in the first accommodation cavity through a cable passing through the top cover 210.

[0059] like Figure 9 and Figure 10As shown, the water outlet device further includes a power supply component 300. A first fitting portion 140 recessed toward the inside of the housing 100 is provided on the side wall of the housing 100. The power supply component 300 is disposed in the first fitting portion 140. The valve element 200 further includes a wireless charging component 280. A second fitting portion 221 recessed toward the inside of the first accommodation cavity is provided on the side wall of the fixing member 220. The wireless charging component 280 is disposed in the first accommodation cavity and corresponds to the position of the second fitting portion 221. The wireless charging component 280 is wirelessly coupled to the power supply component 300, and energy can be provided to the wireless charging component 280 through electromagnetic induction to ensure the normal operation of components such as the induction chip 270 and the driving member 240. This structural design of wireless charging can avoid arranging a power supply cable connecting the valve element 200 and the housing 100, thereby interfering with the movement or overall removal of the valve element 200. In addition, the concave design of the first fitting portion 140 and the second fitting portion 221 is beneficial to reducing the distance between the wireless charging component 280 and the power supply component 300, making the electromagnetic induction effect better and reducing the energy loss of wireless transmission. In Figure 10 In the illustrated embodiment, a through hole is formed in the second fitting portion 221, and the through hole is used to expose the induction coil of the power supply component 300, so as to reduce the interference and energy absorption of the housing 100 material on electromagnetic induction.

[0060] The top end of the first fitting portion 140 defines a first abutting surface 141 protruding from the inner wall of the housing 100, and the top end of the second fitting portion 221 defines a second abutting surface 223 recessed from the outer wall of the fixing member 220. The first abutting surface 141 and the second abutting surface 223 cooperate to limit the downward displacement of the fixing member 220. By providing the first fitting portion 140 and the second fitting portion 221, while shortening the wireless induction distance, it plays a role in restricting the relative movement between the fixing member 220 and the housing 100, and there is no need to separately provide a structure for restricting its movement, saving space.

[0061] An embodiment of the second aspect of the present application further provides a washbasin, such as Figure 1As shown in the figure, it includes a basin body 400, a tabletop 500 and a drainage device mentioned in the above embodiments. The basin body 400 defines a water storage cavity and a drainage port 410 communicating with the water storage cavity. The tabletop 500 is provided with a mounting hole and a mounting groove for mounting the basin body 400. The drainage device passes through the mounting hole, and the water inlet 120 of the drainage device communicates with the drainage port 410 of the basin body 400. Among them, when the water sealing member 230 is in the first position, the top cover 210 protrudes from the tabletop 500, and when the water sealing member 230 is in the second position, the top cover 210 is flush with the tabletop 500. By using the drainage device in the embodiment of the first aspect, the washbasin of this embodiment can determine the current state of the drainage port 410 through the position of the top cover 210 of the drainage device, so as to clearly and intuitively know whether it is necessary to switch the state of the drainage port 410 to achieve the water storage or drainage function.
