Fig. 1 shows a counter basin 100 according to a first embodiment of the present utility model, and fig. 2 shows a state in which the counter basin 100 of fig. 1 is detached from a cover 104 (the cover 104 will be described in detail later). Referring to fig. 1 and 2, the counter basin 100 includes a basin body 101 and a drainer 103, the basin body 101 having a basin cavity 102 capable of receiving water.

Fig. 3 is a sectional view of the tub 100 of fig. 1, and fig. 4 is a sectional view of the drainer 103 of fig. 2. As shown in fig. 4, the drainer 103 includes a drain holder 209, an overflow pipe 201, and a water stop 204. The drain seat 209 is connected with the basin 101, and the drain seat 209 is equipped with the drain passageway 210 that can let water pass through, and the top of drain passageway 210 is the water outlet 206, and the water-stop 204 can seal the water outlet 206. The bottom end of the drain pedestal 209 is adapted to be connected to a drain (not shown) from which water entering the drain channel 210 is subsequently drained. The overflow pipe 201 is provided with an overflow channel 213 and an overflow gap 212, the overflow channel 213 is located inside the overflow pipe 201, and the overflow gap 212 is located on the outer surface of the overflow pipe 201. The overflow pipe 201 is movably connected with the sewer seat 209, and in fig. 4, the overflow pipe 201 can be lifted and lowered relative to the sewer seat 209. The movable connection between the overflow pipe 201 and the drain 209 will be described later. The water stop 204 is fixed relative to the overflow pipe 201, the water stop 204 can move together with the overflow pipe 201, and the water stop 204 and the overflow pipe can move together relative to the sewer base 209. The water stop 204 may be made of rubber.

The water stop 204 is switchable between a closed position and an open position. In fig. 5, the water stop 204 is in the closed position, where the water stop 204 is attached to the top surface of the drain seat 209, the water stop 204 closes the drain port 206, and the basin 102 and the drain port 206 are separated by the water stop 204, i.e., water in the basin 102 cannot pass through the drain port 206. When the water stop 204 is in the closed position, the overflow 212 is lower than the top end of the basin 102. Wherein, the top of the basin 102 refers to the top edge of the side wall of the basin 102. In fig. 6, the water stop 204 is in the open position, where the water stop 204 is disposed above the drain 206 at intervals, the water stop 204 unblocks the drain 206, the drain 206 communicates with the basin 102, and water in the basin 102 can flow through the drain 206 and into the drain channel 210. Referring to fig. 5 and 6, if it is necessary to switch the water stopper 204 from the closed position to the open position, the user needs to move the overflow pipe 201 and the water stopper 204 upward; if it is necessary to switch the water stopper 204 from the open position to the closed position, the user needs to move the overflow pipe 201 and the water stopper 204 downward.

It should be noted that, whether the water stop 204 is in the open position or the closed position, the water stop 204 and the water drain 206 are located below the overflow 212. And, the overflow passage 213 communicates with the drain passage 210 regardless of whether the water stopper 204 is in the open position or the closed position. The overflow path 213 communicates with the drain path 210 in the manner shown in fig. 4. As shown in fig. 4, the drainer 103 further includes a connecting sleeve 203, a water stop 204 is connected to the bottom end of the connecting sleeve 203, the water stop 204 is sleeved outside the connecting sleeve 203, and the connecting sleeve 203 is sleeved outside the overflow pipe 201, so that the relative fixation between the overflow pipe 201 and the water stop 204 is realized. The bottom of the connecting sleeve 203 is in a hub shape, the connecting sleeve 203 is provided with a communication port 214, and the overflow channel 213 and the drain channel 210 are communicated through the communication port 214.

The manner in which the basin 100 is used will be briefly described.

When the user needs to hold the basin 102 with water (e.g., when the user needs to wash clothes in the basin 102, soak something), the user can turn on the faucet and switch the water stop 204 to the closed position. Wherein the faucet is not shown in the drawings, the faucet may be installed at the rear side of the tub 100. Since the drain 206 is closed at this time, water flowing out of the faucet and into the basin 102 cannot enter the drain channel 210 through the drain 206, so that the water in the basin 102 gradually increases.

As the water in the basin 102 increases, when the water level rises to the level of the overflow 212 (with the water stop 204 still in the closed position), water can enter the overflow channel 213 from the overflow 212 and then the drain channel 210, and can be drained away. As such, the water surface remains adjacent to the overflow 212; because the overflow 212 is positioned below the top end of the basin 102 (when the water stop 204 is in the closed position), water in the basin 102 does not overflow from the basin 102 and flow to the ground.

When it is desired to completely drain the water in the basin 102, the user can turn off the faucet and switch the water stop 204 to the open position, allowing the water in the basin 102 to enter the drain channel 210 through the drain 206, thereby allowing the water in the basin 102 to drain.

In summary, water entering the drainer 103 from the overflow 212, and water entering the drainer 103 from the drain 206 can be drained from the drain passage 210 of the drain seat 209. The drainer 103 of the basin 100 itself has an overflow channel 213, and the basin 100 only needs to cooperate with a drain pipe connected to the drain seat 209 to prevent water from overflowing from the basin 102. Therefore, the counter basin 100 of the present utility model requires fewer pipes to be matched, and the counter basin 100 has lower installation cost and higher installation convenience.

It should be noted that, in the first embodiment, the overflow pipe 201 and the water stop 204 may be lifted and lowered relative to the water outlet 209, so as to switch the position of the water stop 204; however, in other embodiments, the overflow 201 and the water stop 204 may also move in a translational manner relative to the drain 209, so long as the water stop 204 can close and open the drain 206. In the first embodiment, when the water stop 204 is in the closed position, the overflow 212 is completely below the top end of the basin 102; in other embodiments, however, the overflow 212 can be only partially below the top of the basin 102. For example, when the water stop 204 is in the closed position, the top wall of the weir 212 is above the top end of the basin 102, but the bottom wall of the weir 212 is below the top end of the basin 102. In addition, in other embodiments, the drainer 103 may not include the connecting sleeve 203, and the water stop 204 is directly and fixedly connected to the overflow pipe 201.

The counter basin 100 of the present utility model is further described below.

Referring to fig. 4, in the first embodiment, the connection sleeve 203 is sleeved outside the overflow pipe 201, and the overflow port 212 of the overflow pipe 201 is exposed outside the connection sleeve 203 so as not to cover the overflow port 212 by the connection sleeve 203. And, the connection sleeve 203 and the overflow pipe 201 are vertically arranged, the connection sleeve 203 is in threaded connection with the overflow pipe 201, and if the overflow pipe 201 rotates relative to the connection sleeve 203, the overflow pipe 201 can lift relative to the connection sleeve 203. When it is necessary to adjust the height of the overflow pipe 201, the user can twist the overflow pipe 201. The advantages of this arrangement are that: on the one hand, since the overflow pipe 201 can be lifted, the height of the overflow port 212 can be adjusted, and the maximum water level in the basin 102 can be adjusted when the water stop 204 is at the closed position; on the other hand, if the height of the overflow 212 deviates from the preset height due to processing errors, assembly errors, etc., the user can adjust the height of the overflow 201, thereby correcting the height of the overflow 212. In addition, since the screw thread has self-locking property and the connection sleeve 203 and the overflow pipe 201 are screw-coupled, there is no need to fix the position of the overflow pipe 201 with respect to the connection sleeve 203 by additionally provided parts in the drainer 103.

Referring to fig. 4, the drainer 103 further includes a positioning nut 202, the positioning nut 202 is sleeved outside the overflow pipe 201, and the positioning nut 202 is screwed with the overflow pipe 201. After the height adjustment of the overflow pipe 201 is completed, the user can tighten the positioning nut 202 so that the bottom surface of the positioning nut 202 abuts against the top surface of the connecting sleeve 203. The positioning nut 202 serves to reduce the risk of the position of the overflow pipe 201 being changed relative to the connection sleeve 203.

It should be noted that, in order to adjust the height of the overflow pipe 201 relative to the connecting sleeve 203, in other embodiments, the connection between the overflow pipe 201 and the connecting sleeve 203 may be configured as a sliding connection. Specifically, the outer circumferential surface of the overflow pipe 201 and the inner circumferential surface of the connection sleeve 203 may not be provided with threads, and the overflow pipe 201 may be slid up and down with respect to the connection sleeve 203; the drainer 103 further includes a locking member (not shown), which may be a latch, a screw, etc., connected to the connection sleeve 203, and the overflow pipe 201 is provided with a plurality of locking holes arranged at intervals in the vertical direction; after the overflow pipe 201 is lifted up and down with respect to the connection sleeve 203, the locking member may be inserted into different locking holes, thereby fixing the overflow pipe 201 at different heights.

Referring to fig. 1 and 2, the basin 100 further includes a shielding cover 104, wherein the shielding cover 104 is detachable from the basin body 101, one of the sidewalls of the basin 102 is provided with a mounting groove 105, and at least a portion of the shielding cover 104 is disposed in the mounting groove 105. Referring to fig. 2 and 3, the shielding cover 104 and the wall surface of the mounting groove 105 define a housing chamber 107, and at least a part of the drainer 103 is disposed in the housing chamber 107. As shown in fig. 5, the bottom end of the shielding cover 104 is provided with a water passing port 106, the accommodating cavity 107 is communicated with the basin 102 through the water passing port 106, and water in the basin 102 can firstly enter the accommodating cavity 107 from the water passing port 106 and then enter the overflow port 212 or the water draining port 206. In this arrangement, the drain 103 is not located in the basin 102, and the shield 104 shields the drain 103, resulting in a higher overall aesthetic appearance of the basin 100. Further, in order to enhance the shielding effect on the drainer 103, the shielding cover 104 may be made of an opaque material, for example, the shielding cover 104 may be made of metal. When a user needs to repair the drainer 103, the user can remove the cover 104 from the mounting groove 105.

Referring to fig. 5, the top end of the shield 104 is provided with a dodging through hole 221, and the top end of the overflow pipe 201 is penetrated in the dodging through hole 221. The escape through hole 221 facilitates the user to contact the overflow pipe 201 of the drainer 103, thereby facilitating the user to switch the position of the water stop 204.

Referring to fig. 4, the drainer 103 further includes a bouncing component 220, the connecting sleeve 203 is movably connected with the sewer seat 209 through the bouncing component 220, after the user presses the overflow pipe 201 once, the water stop 204 can switch the position once, and after the user presses the overflow pipe 201 once again, the water stop 204 resets. The finger of the user may be extended to the escape through hole 221 to press the overflow pipe 201. The bouncing component 220 is provided to facilitate the user to switch the position of the water stop 204.

Fig. 7 is an exploded view of the basin 100 of the first embodiment, and the bouncing component 220 includes a fixed base 218, a movable base 216, an elastic member 222, and a card needle 219. The fixed seat 218 is fixedly connected with the sewer seat 209, and the movable seat 216 is fixedly connected with the connecting sleeve 203. Specifically, referring to fig. 4, the bouncing assembly 220 further includes a stop collar 217, the fixed seat 218, the movable seat 216 and the stop collar 217 are all disposed in the sewer 210, the sewer 209 includes a barrier 211, the stop collar 217 is disposed above the barrier 211, the stop collar 217 is hub-shaped so that water can pass through the stop collar 217, the stop collar 217 is sleeved outside the fixed seat 218, and the stop collar 217 is in threaded connection with the fixed seat 218. I.e. the fixed seat 218 is fixedly connected with the sewer seat 209 through the limit sleeve 217. The top end of the movable seat 216 is in threaded connection with the connecting sleeve 203.

The movable seat 216 is shaped as shown in fig. 9 and 10, and the movable seat 216 includes a peripheral portion 301 and a central portion 302, the peripheral portion 301 being disposed around the central portion 302, the peripheral portion 301 being spaced from the central portion 302 so as to form a guide slot 307, the guide slot 307 itself being connected end to end. Referring to fig. 7, the tip of the card pin 219 is disposed in the guide groove 307. By end-to-end of the guide slot 307 is meant that the tip of the needle 219 is able to slide in the guide slot 307 and around the central portion 302 for at least one revolution. The movement trace of the tip of the card needle 219 in the guide groove 307 is heart-shaped. Referring to fig. 7, the bottom end of the needle 219 is rotatably connected to the fixing base 218, so that the top end of the needle 219 can swing. Referring to fig. 8, two ends of the elastic member 222 are respectively connected to the fixed seat 218 and the movable seat 216, and the elastic force of the elastic member 222 is used to drive the movable seat 216 to move upward relative to the fixed seat 218.

The principle of operation of the bouncing assembly 220 is described below. Fig. 11 (a) to 11 (d) sequentially show a process in which the tip of the card pin 219 surrounds the center portion 302 for one week.

In fig. 11 (a), the tip of the needle 219 is in the first position 401. Accordingly, the water stop 204 is at the open position. In this embodiment, the first position 401 is the bottom end of the guiding slot 307. As shown in fig. 8, when the elastic member 222 is in a compressed state, the bottom end of the elastic member 222 abuts against the fixed seat 218, the top end of the elastic member 222 abuts against the movable seat 216, and the elastic force of the elastic member 222 can drive the movable seat 216 to move upwards. Therefore, the top end of the clip 219 may abut against the wall surface of the bottom end of the guide groove 307 by the elastic force of the elastic member 222, so that the clip 219 is kept at the first position 401, and the water stop 204 is kept closed to the water drain 206.

As shown in fig. 9 and 10, the guide groove 307 includes a first section 303, a second section 304, a third section 305, and a fourth section 306, which are connected end to end in this order. Referring to fig. 11 (a) and 11 (b), after the user presses down on the overflow pipe 201, the movable seat 216 moves downward with respect to the fixed seat 218, the tip of the card pin 219 slides along the first section 303, and then the tip of the card pin 219 subsequently enters the second section 304. Since the depth of the tip of the first section 303 is smaller than the depth of the tip of the second section 304, the sidewall of the second section 304 can prevent the tip of the needle 219 from retracting from the second section 304 to the first section 303. Referring to fig. 11 (b) and 11 (c), after the user releases the pressing of the overflow pipe 201, the movable seat 216 moves upward with respect to the fixed seat 218 under the elastic force of the elastic member 222, and the tip of the clip 219 slides leftwards and downwards along the second section 304. Subsequently, the tip of the needle 219 enters the third section 305 from the second section 304, and the tip of the needle 219 abuts against the tip of the central portion 302 under the elastic force of the elastic member 222, thereby being held at the second position 402. In this embodiment, the second location 402 is the top end of the central portion 302, i.e., the junction of the third segment 305 and the second segment 304. As shown in fig. 8, when the tip of the card 219 is in the second position 402, the water stop 204 is in the closed position.

Referring to fig. 11 (c) and 11 (d), after the user presses down on the overflow pipe 201 again, the movable seat 216 moves downward, and the tip of the card pin 219 slides upward and leftward along the third section 305 and enters the fourth section 306. The depth of the tip of the fourth segment 306 is greater than the depth of the tip of the third segment 305 so as to prevent the tip of the stuck needle 219 from retracting from the fourth segment 306 to the third segment 305. The user then releases the overflow 201 and the tip of the catch 219 slides along the fourth segment 306 under the force of the resilient member 222 and returns to the first position 401. The depth of the bottom end of the fourth section 306 is smaller than the depth of the bottom end of the first section 303, so that when the top end of the needle 219 is in the first position 401 and the user presses the overflow pipe 201, the top end of the needle 219 slides along the first section 303 but not along the fourth section 306.

Referring to fig. 7, the elastic assembly further includes a limiting member 215, the movable seat 216 is provided with a limiting groove 223 extending in a vertical direction, the limiting member 215 is connected with the fixed seat 218, and a portion of the limiting member 215 is slidably disposed in the limiting groove 223. The limiting member 215 is provided as a screw in this embodiment. The cooperation between the limiting member 215 and the limiting groove 223 is used for guiding the movable seat 216, so as to prevent the movable seat 216 from rotating.

In some embodiments, as shown in fig. 6, the weirs 212 are provided on the outer circumferential surface of the weirs 201. The advantage of this arrangement is that the top surface of the overflow pipe 201 may not need to be perforated, and the area of the top surface of the overflow pipe 201 that can be pressed by the user is larger, which is more convenient and comfortable when the user presses the overflow pipe 201.

Referring to fig. 5, when the water stopper 204 is in the closed position, the top surface of the overflow pipe 201 is flush with the top surface of the cover 104, which is advantageous in improving the overall aesthetic appearance of the counter basin 100. Referring to fig. 6, when the water stopper 204 is in the open position, the top end of the overflow 212 is not higher than the top surface of the cover 104, so that the overflow 212 can be placed to be exposed to the outside of the cover 104, thereby improving the overall aesthetic appearance of the tub 100.

Referring to fig. 7, the drainer 103 further includes an upper seal 205, a lower seal 207, and a lock nut 208 that are sleeved outside of the drain seat 209. The upper seal 205 is clamped between the drain seat 209 and the basin 101, the lock nut 208 is threadedly coupled to the drain seat 209, and the lower seal 207 is clamped between the bottom surface of the basin 101 and the top surface of the lock nut 208. The upper seal 205 and the lower seal 207 may each be made of rubber. The upper seal 205 and the lower seal 207 serve to reduce the risk of water leaking from the gap between the drain pedestal 209 and the basin 101.

Fig. 12 and 13 illustrate a counter basin 100 in another embodiment of the present utility model. The specific arrangement of the drainer 103 of fig. 13 is referred to above and will not be repeated here. The main difference between the counter basin 100 of fig. 12 and the counter basin 100 of fig. 1 is the arrangement of the basin body 101. In fig. 12, the tub body 101 of the counter tub 100 is of an integral structure, that is, the tub body 101 is integrally formed. The basin 100 may be made of ceramic or metal. The basin 101 includes a main body 108 and a receiving portion 109, the main body 108 is provided with a basin 102, the receiving portion 109 is protruded from one of side walls of the basin 102, the receiving portion 109 is further provided with a receiving chamber 107, and at least a part of the drainer 103 is disposed in the receiving chamber 107. The accommodating part 109 is also provided with a water passing port 106, the water passing port 106 is positioned at the bottom end of the accommodating part 109, and the pelvic cavity 102 and the accommodating cavity 107 are communicated through the water passing port 106. The top end of the receiving chamber 107 is open, and the drainer 103 can be moved into and out of the receiving chamber 107 from the top end of the receiving chamber 107 during the mounting or dismounting of the drainer 103. The counter basin 100 further includes a shielding cover 111, and the shielding cover 111 is connected to the top end of the overflow pipe 201 and covers the receiving chamber 107. The shielding cover 111 and the overflow pipe 201 may be connected by a connection method such as a clamping connection or a threaded connection. The counter basin 100 shown in fig. 12 has the advantage that the portion of the drainer 103 that can be directly observed by the user is reduced by shielding the drainer 103 by the accommodating portion 109, thereby improving the aesthetic appearance of the counter basin 100. Moreover, since the shielding cover 111 is not provided with the escape through hole 221 for the overflow pipe 201 to pass through, the tub 100 has a high aesthetic appearance. When the user needs to switch the state of the drainer 103, the user may directly press the shielding cover 111.

Referring to fig. 12, the counter basin 100 is provided with a tap mounting hole 110, and the tap mounting hole 110 is located on the same side of the basin 102 as the shielding cover 111 and is disposed adjacent thereto. Faucet mounting holes 110 are used to mount a faucet. The counter basin 100 provided with the faucet mounting hole 110 facilitates assembly between the counter basin 100 and a faucet. Also, since the tap mounting hole 110 and the shielding cover 111 are located at the same side of the tub 102 and are adjacently disposed, the distance between the tap and the shielding cover 111 is short, and the distance that the user's hand moves between the tap and the shielding cover 111 is short, the user can rapidly switch the state of the drainer 103 after switching the state of the tap. Thus, the counter basin 100 shown in FIG. 12 is advantageous for enhancing the user's use experience.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
