Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and in particular to a portable water quality detector. Background Art

[0002] Water quality testing typically involves examining the amount of metallic lead, dissolved oxygen, pH, and bacterial counts in water. For example, total dissolved solids (TDS) can be measured to determine the water's total mineralization. A Chinese utility model patent, published with publication number CN206772960U and titled "A Water Quality Testing Pen," utilizes a movable absorbent block within the pen cap to wipe moisture from the detector's probe, preventing detection errors caused by residual moisture.

[0003] However, since the water absorbent block and the probe are separated by a sealing plate, the sealing performance of the sealing plate will directly affect whether the pen cap can serve as a water container for the detector. If the sealing performance is poor, there will be problems such as water leakage and the water absorbent block will remain wet for a long time. In addition, the water absorbent block is fixed to the pen cap by a number of screws. Since the water absorbent block is a consumable item, this fixing method is cumbersome to operate and can easily damage the inner wall of the pen cap. Summary of the Invention

[0029] It should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] The following will be combined with the Figure 1-7 , the present invention is further described.

[0031] A portable water quality detector includes a detector body 1, wherein the detector body 1 has a first end face 101 and a second end face 102 disposed opposite to each other, a probe 103 is provided on the first end face 101, and further includes:

[0032] a first cover 2 detachably covering the first end surface 101 to cover or expose the probe 103 ;

[0033] The second cover 3 is detachably covered on the second end surface 102 and has two ends open. A water absorbent block 6 for wiping the probe 103 is provided in the second cover 3;

[0034] A quick-release assembly, which includes a clamping portion 4 extending into the second cover body 3, and a pressing portion 5 partially exposed in the second cover body 3. The clamping portion 4 is located on the pressing path of the pressing portion 5, and has an initial state of clamping the water absorbent block 6 and a deformed state of releasing the water absorbent block 6. One end of the pressing portion 5 hidden in the second cover body 3 is spaced apart from the clamping portion 4. When the pressing portion 5 is pressed, the pressing portion 5 is used to abut against the clamping portion 4, and switch the clamping portion 4 from the initial state to the deformed state, so that the water absorbent block 6 is separated from the clamping portion 4 and / or the second cover body 3.

[0035] In this embodiment, Figure 1-Figure 3As shown, the detector body 1 includes a first end face 101 and a second end face 102 that are arranged in opposite directions. A probe 103 is provided on the first end face 101. The probe 103 is connected to the circuit structure in the detector body 1, such as using the conductive substance in the water to detect whether the suspended solids, heavy metals and conductive ions in the water are too high; different application environments are adapted to different probes 103; of course, in order to facilitate the replacement of different probes 103, the probe 103 can be installed on the first end face 101 of the detector body 1 in a plug-in manner. The above is the existing technology and will not be repeated here. Figure 1 As shown, a first cover body 2 and a second cover body 3 are detachably covered on the first end face 101 and the second end face 102 of the detector body 1, respectively. The first cover body 2 can cover or expose the probe 103, which not only protects the probe 103 and prevents dust; but also can be used alone as a water container. When in use, the first cover body 2 is filled with water to be tested, and then the probe 103 is inserted into the water to be tested to perform a rapid test; the water absorbent block 6 in the second cover body 3 is used to wipe the probe 103 after the test is completed, so that it can always remain in a dry state for re-testing, avoiding the situation where errors in the test results are caused by residual moisture; the independently arranged first cover body 2 and the second cover body 3 can be used alone without affecting each other, and are respectively covered on the two end faces of the detector body 1, which are easy to carry and not easy to lose.

[0036] On the other hand, Figure 3 and Figure 5As shown, both ends of the second cover 3 are open structures, which have an inner chamber, and the water absorbent block 6 is located in the inner chamber. In order to facilitate the rapid installation and removal of the water absorbent block 6, the detector also includes a quick-release assembly, which includes a pressing portion 5 and a clamping portion 4 arranged at intervals. Part of the pressing portion 5 is exposed in the second cover 3, and the other part extends into the inner chamber and cooperates with the clamping portion 4. The clamping portion 4 is used to clamp or release the water absorbent block 6 (that is, the clamping portion 4 has an initial pressure to clamp the water absorbent block 6). When in use, an external force acts on the end of the pressing portion 5 exposed from the second cover body 3, prompting the end of the pressing portion 5 hidden in the second cover body 3 to move toward the clamping portion 4 until it abuts against the clamping portion 4, and then pushes the clamping portion 4 to switch from the initial state to the deformed state, thereby causing the clamping portion 4 to release the water absorbing block 6, and the water absorbing block 6 can fall out of the second cover body 3 after being separated from the clamping portion 4; on the contrary, after the external force disappears, the pressing portion 5 returns to its original position, and the clamping portion 4 is tightened. When the water absorbing block 6 is in the second cover body 3, the second cover body 3 is slid back and forth on the first end surface 101 so that the water absorbing block 6 can contact the probe 103 and wipe the moisture attached to it; when not in use, the second cover body 3 is covered on the second end surface 102 of the detector body 1, so that the water absorbing block 6 can be stored in the detector body 1 to form a whole, which is convenient for carrying; the pressing part 5 can push the clamping part 4 to release the water absorbing block 6 under the action of external force, and the clamping part 4 can be restored to the initial state after the external force disappears. During the switching process, the water absorbing block 6 can be quickly disassembled and installed, so as to facilitate the replacement of the water absorbing block 6. The process is simple and easy to operate, which replaces the problem of drilling threaded holes on the second cover body 3 to destroy the integrity of the second cover body 3, and the problem of loose fixation of the water absorbing block 6 after too much replacement frequency.

[0037] The clamping portion 4 includes two fork-shaped hinged rods 401 arranged opposite to each other, and two sets of first connecting rods 402 and second connecting rods 403 for connecting the upper ends and lower ends of the two fork-shaped hinged rods 401 respectively;

[0038] The pressing part 5 includes a pressing head 501, a support rod 502 and a pressing protrusion 503 connected in sequence, and a return spring 504 sleeved on the support rod 502. The pressing head 501 is exposed on the second cover body 3, and the end of the support rod 502 away from the pressing head 501 extends into the second cover body 3, and the pressing protrusion 503 is arranged at a distance from the first connecting rod 402. In the deformed state, the first connecting rod 402 is used to move in the same direction as the pressing protrusion 503, and the second connecting rod 403 releases the water absorbent block 6.

[0039] In this embodiment, Figure 5 、 Figure 7As shown, the clamping part 4 includes a fork-shaped hinged rod 401, a first connecting rod 402 and a second connecting rod 403. The two fork-shaped hinged rods 401 are respectively hinged on the left and right sides of the second cover body 3. When the fork-shaped hinged rod 401 is pressed down, the opening of the fork-shaped hinged rod 401 gradually increases; conversely, when the external force acting on the hinged rod disappears, the opening of the fork-shaped hinged rod 401 gradually decreases; the two first connecting rods 402 are respectively used to connect to the front and rear ends of the upper ends of the two fork-shaped hinged rods 401, and the two second connecting rods 403 are respectively used to connect to the front and rear ends of the lower ends of the two fork-shaped hinged rods 401. The first connecting rod 402 and the second connecting rod 403 arranged at intervals above and below are a group. The water absorbent block 6 is placed between the two second connecting rods 403. With the cooperation of the two fork-shaped hinged rods 401, the two second connecting rods 403 can clamp or release the water absorbent block 6.

[0040] like Figure 6 As shown, the pressing portion 5 includes a pressing head 501, a support rod 502 and a pressing protrusion 503 connected in sequence from top to bottom. In order to reset the pressing portion 5 as a whole, the pressing portion 5 also includes a reset spring 504 sleeved on the support rod 502; specifically, the pressing head 501 is used to be exposed on the second cover body 3, so that an external force can directly act on the pressing head 501, and the end of the support rod 502 away from the pressing head 501 extends into the second cover body 3 so that the pressing protrusion 503 cooperates with the first connecting rod 402, that is, in the initial state, the pressing protrusion 503 and the first connecting rod 402 are arranged at an upper and lower intervals, so that when there is no external force, the pressing protrusion 503 and the first connecting rod 402 and the water absorbent block 6 are in a relatively static state, at this time, it is used to store the water absorbent block 6 or the probe 10 3 for wiping; in the deformed state, the pressing head 501 is pressed downward, so that the pressing head 501 transmits the force to the pressing protrusion 503 through the support rod 502, prompting the pressing protrusion 503 to gradually approach the first connecting rod 402 until it abuts against it. Under the continuous pressure of the external force, the pressing protrusion 503 pushes the first connecting rod 402 to move downward, thereby deforming the fork-shaped hinged rod 401, and then the two second connecting rods 403 move away from each other to release the water absorbing block 6 therebetween, thereby realizing the function of quickly disassembling the water absorbing block 6; similarly, when installing the water absorbing block 6, the water absorbing block 6 is placed in the second cover body 3 and the pressing head 501 is released to reset the various components. At this time, the two second connecting rods 403 clamp the water absorbing block 6 in the second cover body 3, which will not be described in detail here.

[0041] By pressing the pressing head 501 and transmitting the force through the support rod 502 and the pressing protrusion 503, the fork-shaped hinge can be deformed and drive the two second connecting rods 403 to move away from each other, thereby releasing the water absorbing block 6; there is no need to repeatedly disassemble and install screws in this process, and the operation process is simple; the downward pressing method of replacing the water absorbing block 6 is faster and more convenient.

[0042] An integrated stopper 7 is provided in the second cover 3 . The stopper 7 is provided with a through hole for the support rod 502 to pass through. The return spring 504 is located between the pressing head 501 and the stopper 7 .

[0043] In this embodiment, Figure 5 As shown, in order to reset the pressing head 501 and the pressing protrusion 503, an integrated stopper 7 is provided in the second cover body 3. The stopper 7 is used to close the second cover body 3 and is provided with a through hole for allowing the support rod 502 to pass through the gap. The return spring 504 is sleeved on the support rod 502 and is located between the pressing head 501 and the stopper 7. In this way, when the clamping member switches from the initial state to the deformed state, the pressing head 501 moves downward and compresses the return spring 504. At this time, the support rod 502 can slide downward at the through hole and move the pressing protrusion 503 in the same direction with it; when the pressing head 501 is released, the compressed return spring 504 is reset to push the pressing head 501 to reset upward, so that the pressing protrusion 503 is gradually separated from the first connecting rod 402, so that the second connecting member can clamp the water absorbent block 6 in the second cover body 3.

[0044] In the initial state, the pressing protrusion 503 abuts against the end of the stopper 7 facing away from the return spring 504 .

[0045] like Figure 5 As shown, in order to prevent the pressing protrusion 503 from moving too long and thus being unable to push the first connecting rod 402 to move in the same direction during the process of pressing the pressing head 501, in the initial state, the pressing protrusion 503 can abut against the end of the block 7 away from the return spring 504 to limit the moving distance of the pressing protrusion 503 and prevent the pressing protrusion 503 from separating from the second cover body 3.

[0046] The pressing protrusion 503 and the first connecting rod 402 are perpendicular to each other.

[0047] In this embodiment, Figure 5 As shown, in order to enable the pressing protrusion 503 to push the first connecting rod 402 to move downward and avoid a large distance between the two and a lack of contact, the pressing protrusion 503 and the first connecting rod 402 are arranged vertically. In this way, under the action of the pressing head 501, the pressing protrusion 503 can always be connected with the first connecting rod 402 and push the first connecting rod 402 to move in the same direction as it.

[0048] A limiting protrusion 8 extending in a direction away from the first end face 101 is provided on the second end face 102. The second cover body 3 has a storage state in which it is positively covered on the second end face 102 and a ventilation state in which it is reversely covered on the second end face 102. In the storage state, the limiting protrusion 8 abuts against the water absorbing block 6. In the ventilation state, the limiting protrusion 8 abuts against the pressing head 501, so that the pressing protrusion 503 is in contact with the first connecting rod 402.

[0049] In this embodiment, Figure 4 As shown, a limiting protrusion 8 extending away from the first end face 101 is provided on the second end face 102, and the second cover body 3 has a storage state in which it is positively covered on the second end face 102 and a ventilation state in which it is reversely covered on the second end face 102. When the second cover body 3 is in the storage state, that is, the limiting protrusion 8 and the pressing head 501 are spaced apart, the water absorbing block 6 can abut against the limiting protrusion 8 at this time, and the limiting protrusion 8 plays a supporting and limiting role relative to the water absorbing block 6, which can avoid the water absorbing block 6 from being separated from the second cover body 3 due to accidental touching of the pressing head 501; when the second cover body 3 is in the ventilation state When the second cover 3 is reversely closed on the second end surface 102, the limiting protrusion 8 abuts against the pressing head 501, and the opening of the second cover 3 is set in the direction to open the water-absorbing block 6 therein for drying. On the other hand, in order to prevent the water-absorbing block 6 from escaping from the second cover 3 in the ventilation state, when the limiting protrusion 8 abuts against the pressing head 501, the pressing protrusion 503 is in contact with the first connecting rod 402, that is, the pressing protrusion 503 lightly touches the first connecting rod 402, avoiding pushing the first connecting rod 402 to cause the second connecting rod 403 to release the water-absorbing block 6. Specifically, when the initial state is switched to the deformed state, the moving distance of the pressing protrusion 503 is d1, and when the storage state is switched to the ventilation state, the moving distance of the pressing protrusion 503 is d2, and d1 and d2 satisfy d1>d2. When the pressing protrusion 503 moves a distance d1, the second connecting rod 403 can gradually release the water-absorbing block 6 through the first connecting rod 402 and the fork-shaped connecting rod under the action of the pressing protrusion 503; when the pressing protrusion 503 moves a distance d2, the pressing protrusion 503 can fit with the first connecting rod 402. At this time, the pressing protrusion 503 does not prompt the first connecting rod 402 to move downward, so that in the ventilation state, the second connecting rod 403 can still clamp the water-absorbing block 6 in the second cover body 3 to keep the water-absorbing block 6 dry.

[0050] The second cover 3 can be placed on the second end face 102 of the detector body 1 in either the forward or reverse direction. When placed in the forward direction, the absorbent block 6 can be stored in the second cover 3 to prevent it from being lost. When placed in the reverse direction, the absorbent block 6 can be exposed to the air and kept dry by airing it out, thereby reducing detection errors caused by residual moisture on the absorbent block 6 being wiped onto the probe 103. At the same time, whether the second cover 3 is in the stored state or the ventilated state, the limiting protrusion 8 can function as a limiter (i.e., in the stored state, the limiting protrusion 8 limits the absorbent block 6; in the ventilated state, the limiting protrusion 8 limits the pressing portion 5). These two limiting functions can prevent the pressing portion 5 from being accidentally touched as a whole, making the detector easy to carry.

[0051] The second cover 3 is provided with a plurality of ventilation holes 9 .

[0052] In this embodiment, Figure 1 As shown, ventilation holes 9 are provided on the second cover 3 to prevent the water vapor evaporated from the water absorbing block 6 from remaining in the second cover 3. The provision of the ventilation holes 9 can also accelerate the drying of the water absorbing block 6.

[0053] The first cover 2 and the second cover 3 are respectively provided with different anti-slip patterns.

[0054] In this embodiment, Figure 1 As shown, in order to facilitate quick distinction between the first cover body 2 and the second cover body 3, different anti-slip patterns are respectively provided on the first cover body 2 and the second cover body 3. The anti-slip patterns can also increase the friction with the palm to achieve the purpose of quick disassembly and quick assembly of the first cover body 2 and / or the second cover body 3.

[0055] The water absorbing block 6 has a plurality of wiping holes for the probe 103 to pass through.

[0056] In this embodiment, in order to make Figure 3 As shown, in order to increase the contact area between the water absorbing block 6 and the probe 103 and reduce the cleaning dead angle, the water absorbing block 6 is provided with a wiping hole, which is used for the probe 103 to pass through when wiping the probe 103.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
