Description

Technical Field

[0001] The utility model relates to the field of detection instruments, in particular to a pH electrode washing device. Background Art

[0002] In the pH determination method for water quality testing, the glass electrode (commonly used such as the electrode of the Hach pH tester) is soaked in pure water for more than 24 hours before use. The pH needs to be positioned before testing. After positioning, the electrode needs to be slowly rinsed with pure water several times using a washing bottle, and then rinsed with water sample 6 to 8 times, and then inserted into the water sample. The pH value can be read directly from the instrument after 1 minute.

[0003] During this process, the pH electrode is not only frequently rinsed, but also has high requirements for the rinsing quality of the electrode. The current main rinsing method is that the operator holds the electrode handle in one hand and a washing bottle (sometimes a test tube or a small beaker is used instead) in the other hand to slowly pour and rinse. This not only makes manual operation easy to fatigue, but also makes it difficult to control the rinsing quality of the electrode.

[0004] Utility model patent CN219224656U discloses a pH measuring device that uses a dedicated rinsing tank and a nozzle to rinse the electrode from the side. This method is difficult to achieve effective rinsing and difficult to control the nozzle to thoroughly rinse the electrode. Furthermore, it cannot be operated when rinsing with a water sample.

[0005] Based on this, the present application proposes a pH electrode washing device. Utility Model Content

[0024] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0025] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0028] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] In this utility model, if Figure 1-2 As shown, a pH electrode washing device is provided, comprising: a collecting tank 1, the collecting tank 1 having a water cavity with an open top; a water sprinkling ring 2, arranged in the water cavity of the collecting tank 1 or on the upper side of the cavity opening of the water cavity of the collecting tank 1, the water sprinkling ring 2 comprising an annular bottom 201 and a side 202 surrounding the bottom 201; a water supply component, comprising a water supply pipe 3, the water supply pipe 3 being connected to the water sprinkling ring 2 so that the water supply pipe 3 can supply water to the upper side of the bottom 201; a fixing assembly, comprising a clamping portion 4 capable of clamping a handle of a fixed electrode 13, and when the handle of the electrode 13 is clamped and fixed in the clamping portion 4, the vertical projection of the electrode 13 can pass through the bottom 201.

[0030] When the electrode 13 needs to be rinsed, the rinse device of the present invention passes the lower section of the electrode 13 through the inner side of the water spraying ring 2, and the handle of the electrode 13 is fixed to the clamping part 4. At this time, water can be supplied to the inner side of the water spraying ring 2 through the water supply pipe 3. The water supplied by the water supply pipe 3 to the inner side of the water spraying ring 2 accumulates in the water spraying ring 2 and surrounds the circumference of the electrode 13, so that the water flows down from the gap between the bottom 201 of the water spraying ring 2 and the electrode 13, so that the water in the water spraying ring 2 can be sprayed downward along the circumference of the electrode 13 more evenly, so as to fully rinse the circumference of the detection part of the electrode 13. After rinsing the detection part of the electrode, the electrode 13 can be moved upward so that the detection head position at the bottom of the electrode 13 is located at the water spraying position inside the water spraying ring. At this time, the water spraying can directly rinse the detection head position at the bottom of the electrode 13.

[0031] When the water sprinkling device of the present invention is performing water sprinkling, the electrode 13 is fixed by a fixing assembly, and water is sprayed through the water sprinkling ring 2, thereby reducing the difficulty and fatigue of the operator in holding the electrode 13 and aligning the hand-held washing bottle, and the problem of water sprinkling uniformity can also be solved by the water sprinkling ring 2 sprinkling water downward in a ring shape.

[0032] It should be noted that in order to show the internal structure of the collection tank, Figure 1A wall of the collecting tank is removed; Figure 1 The water supply pipe is drawn in the figure, which does not affect the technical personnel in this field. Figure 1 The structure shown is used to understand the connection method of the water supply pipe of the present invention.

[0033] In a preferred embodiment, for the structure of the present invention, a further optimized setting is that the water spray ring 2 includes two split semi-ring bodies 5, and the semi-ring bodies 5 are respectively provided with the bottom 201 and the side 202. The two semi-ring bodies 5 are respectively slidably arranged in the collecting trough 1, and the two semi-ring bodies 5 can slide and switch between the spliced ​​state and the separated state.

[0034] As shown in the figure, by setting the water sprinkling ring 2 into two semi-ring bodies 5, the semi-ring bodies 5 can be moved to a separated state when the electrode 13 is installed on the fixed bracket 6 or removed from the fixed bracket 6, so as to prevent the semi-ring bodies 5 from interfering with the installation of the electrode 13, and to prevent the water sample contaminated on the surface of the electrode 13 from contaminating the water sprinkling ring 2, so as to further maintain the water sprinkling effect.

[0035] After the electrode 13 is placed in place, the half rings 5 ​​can be moved to a spliced ​​state to form a complete water spraying ring 2, and the water spraying operation can be carried out at this time.

[0036] In a preferred embodiment, for the structure of the present invention, more specifically, the rinsing device also includes a fixed bracket 6, the fixed bracket 6 is installed with the semi-ring body 5, and the bottom 201 of the fixed bracket 6 has a slider 7 that slides with the cavity mouth of the water cavity.

[0037] In a preferred embodiment, for the structure of the present invention, more specifically, the slider 7 is configured as a plastic slider 7 or a silicone slider 7 , and the slider 7 abuts against the side wall of the collecting tank 1 .

[0038] As shown in the figure, by setting the slider 7 to be a plastic slider 7 or a silicone slider 7, the friction between the slider 7 and the groove wall of the collection groove 1 can be increased to prevent the water spraying ring 2 from moving freely during the water spraying operation.

[0039] In a preferred embodiment, for the structure of the present invention, more specifically, the semi-ring body 5 is detachably connected to the fixing bracket 6, so that the water spray ring 2 can be easily cleaned and replaced.

[0040] In a preferred embodiment, for the structure of the present invention, to be more specific, the fixed bracket 6 includes: a base body 601, supporting the bottom 201 of the semi-ring body 5; a connecting rib 602, which can abut against the outer surface of the side 202 of the semi-ring body 5, and a hook 603 is formed on the top of the connecting rib 602, and the hook 603 can be engaged with the upper edge of the side 202 of the semi-ring body 5.

[0041] As shown in the figure, when installing the semi-ring body 5 on the fixed bracket 6, the bottom 201 of the semi-ring body 5 can be first abutted against the bottom frame 601, and then the upper edge of the side 202 of the semi-ring body 5 can be pressed against the hook 603 to fix the semi-ring body 5 on the fixed bracket 6. When the semi-ring body 5 needs to be removed, the hook 603 can be swung outward and the semi-ring body 5 can be removed by dragging it.

[0042] In a preferred embodiment, the structure of the present invention is further specifically described as follows: the fixing bracket 6 includes two spaced-apart connecting ribs 602. As shown in the figure, the provision of two connecting ribs 602 increases the number of points at which the semi-ring body 5 is fixed, further stabilizing the semi-ring body 5. It also reduces the circumferential dimension of a single connecting rib 602 for fastening and fixing, thereby reducing the difficulty of fastening and fixing.

[0043] In a preferred embodiment, for the structure of the present invention, to be more specific, a side portion 202 of one of the semi-ring bodies 5 is provided with a connecting pipe 8, the water supply pipe 3 is inserted into the connecting pipe 8, and the water supply component also includes a water supply cup 11 connected to the water supply pipe 3.

[0044] As shown in the figure, water can be supplied to the watering ring 2 via the water supply cup 11. In a preferred embodiment, as shown in the figure, a cup holder is provided on one side of the collection tank 1. The cup holder is higher than the watering ring 2. When watering is required, the water supply cup 11 is placed on the cup holder; when watering is not required, the water supply cup 11 is placed lower. During the watering process, the height difference between the water supply cup 11 and the watering ring 2 can be adjusted by holding the water supply cup 11, thereby adjusting the water flow rate from the water supply pipe 3 to the watering ring 2, so that the water in the watering ring 2 accumulates around the electrode 13.

[0045] In a preferred embodiment, the structure of the present invention is further specifically described as follows: the height difference between the lower edge of the connecting pipe 8 and the bottom 201 of the water spray ring 2 is greater than or equal to 2 cm. This allows the connecting pipe 8 to easily create a height difference with the water accumulated in the water spray ring 2, thereby reducing the risk of water accumulated in the water spray ring 2 flowing back into the connecting pipe 8.

[0046] In a preferred embodiment, for the structure of the present invention, to be more specific, the fixing assembly includes a base 9, a support rod 10 arranged on the base 9, a connecting frame that can be vertically slidably arranged on the support rod 10, and an adjusting bolt 12 threadedly engaged with the support rod 10 on the lower side of the connecting frame, and the clamping portion 4 is installed on the connecting frame.

[0047] As shown in the figure, the clamping part 4 can be in the form of an existing pipe clamp. By so setting, the position of the adjusting bolt 12 can be adjusted to adjust the watering position of the electrode 13. The position of the electrode 13 in the water spraying ring 2 can also be slightly adjusted by slightly rotating the connecting frame to further prevent the electrode 13 from having a dead angle in the water spraying. In some embodiments, during the water spraying process, the connecting frame can also be moved up and down so that different positions of the electrode 13 can be directly sprayed with water.

[0048] Among them, regarding the structural form of the connecting frame, as shown in the figure, the connecting frame includes a sleeve that is sleeved on the support rod 10, a cross frame body connected to the sleeve, and the clamping part 4 is fixed to the cross frame body, wherein the sleeve can be set to a plastic sleeve that is interference fit with the support rod 10, so as to prevent the connecting frame from rotating at will.

[0049] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0050] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
