[0041] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0042] In the prior art, pH meter probe cleaning devices include a motor and a cleaning sleeve. During use, the motor drives the cleaning sleeve to move and clean the probe. Because the motor is an electrical component, the pH meter probe cleaning device has certain requirements for its installation environment. This makes it difficult to use in some special environments (such as humid environments), resulting in limited versatility.

[0043] Based on this, the present application provides a cleaning device for a pH meter probe, which can solve the problem of poor versatility of the cleaning device for the pH meter probe.

[0044] Please refer to Figure 1 and Figure 2 , Figure 1 This is a front view of a cleaning device 100 for a pH meter 200 probe 210 in one embodiment of the present application. Figure 2 yes Figure 1 A left side view of the cleaning device 100 is shown.

[0045] An embodiment of the present application provides a cleaning device 100 for a probe 210 of a pH meter 200, comprising a cleaning sleeve 10 and a driving member 20. The cleaning sleeve 10 is used to be mounted on the probe 210 of the pH meter 200, and the driving member 20 is connected to the cleaning sleeve 10. The cleaning device 100 also includes an energy storage component 40, which is connected to the driving member 20. The energy storage component 40 is used to enable the driving member 20 to drive the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200.

[0046] For example, a wiping cloth may be installed on the cleaning cover 10 to clean dirt on the probe 210 .

[0047] Alternatively, the driving member 20 includes a gear and a rack connected in a transmission manner, and the rack is connected to the cleaning sleeve 10. The energy storage assembly 40 can control the gear to rotate around its own axis, thereby driving the rack and the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200.

[0048] It should be noted that the pH meter 200 is generally a slender rod-shaped structure. Figure 1 and Figure 2 , the length direction of the pH meter 200 is parallel to the direction indicated by arrow h and the direction indicated by arrow i. The energy storage assembly 40 can control the driving member 20 to drive the cleaning cover 10 to move in the direction indicated by arrow h, and the energy storage assembly 40 can control the driving member 20 to drive the cleaning cover 10 to move in the direction indicated by arrow i.

[0049] The cleaning device 100 for the probe 210 of the pH meter 200 provided in the embodiment of the present application has a cleaning sleeve 10 for being mounted on the probe 210 of the pH meter 200, the driving member 20 is connected to the cleaning sleeve 10, and the energy storage assembly 40 is connected to the driving member 20. Therefore, the driving member 20 can drive the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200 through the energy storage assembly 40, thereby cleaning the probe 210 of the pH meter 200. There is no need to set up a motor, and there are low requirements for the installation environment. This can solve the problem of poor versatility of the cleaning device 100 for the probe 210 of the pH meter 200.

[0050] The cleaning device 100 for the pH meter 200 probe 210 provided in the embodiment of the present application is a purely mechanical structure, does not require a special installation environment, has a simple structure, and has a low production cost. It can reduce the problem of abnormalities of the probe 210 and can reduce manual operations compared to directly manually wiping the probe 210.

[0051] It should be noted that the driving member 20 can also be directly manually controlled to drive the cleaning cover 10 to reciprocate along the length of the pH meter 200. During the process of manually controlling the driving member 20 to drive the cleaning cover 10 to reciprocate along the length of the pH meter 200, the energy storage assembly 40 can accumulate energy. Therefore, even without manually controlling the driving member 20, the energy stored in the energy storage assembly 40 can be used to enable the driving member 20 to drive the cleaning cover 10 to reciprocate along the length of the pH meter 200.

[0052] For example, the driving member 20 can be configured as a push-pull rod that can be manually controlled to reciprocate along the length of the pH meter 200, thereby driving the cleaning cover 10 to reciprocate along the length of the pH meter 200 and simultaneously storing energy in the energy storage assembly 40. With this configuration, the driving member 20 can be manually controlled to drive the cleaning cover 10 to reciprocate along the length of the pH meter 200, and the energy stored in the energy storage assembly 40 can also be used to enable the driving member 20 to drive the cleaning cover 10 to reciprocate along the length of the pH meter 200.

[0053] Optionally, the energy storage assembly 40 includes an energy storage gear 41 and a first elastic member 42. The energy storage gear 41 is in driving connection with the driving member 20; the first elastic member 42 is connected to the energy storage gear 41. The first elastic member 42 is compressed to accumulate elastic potential energy, which is used to drive the energy storage gear 41 to rotate about its own axis, so that the driving member 20 drives the cleaning sleeve 10 to reciprocate along the length of the pH meter 200.

[0054] By adopting the above solution, the elastic potential energy stored in the energy storage assembly 40 can be used to enable the driving member 20 to drive the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200.

[0055] Optionally, the driving member 20 includes a connecting gear 23 sleeved on the connecting shaft 21 , and the connecting gear 23 is meshed with the energy storage gear 41 .

[0056] Specifically, the first elastic member 42 may be a spring or a spiral spring.

[0057] Please refer to Figure 2 and Figure 4 In this embodiment, the energy storage assembly 40 further includes an energy storage rack 43, which is connected to the first elastic member 42. By moving the energy storage rack 43, the first elastic member 42 can be compressed and accumulate elastic potential energy.

[0058] In this configuration, by moving the energy storage rack 43, the first elastic member 42 can be compressed and accumulate elastic potential energy, so that the elastic potential energy accumulated by the energy storage assembly 40 can be used to enable the driving member 20 to drive the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200.

[0059] Optionally, the energy storage rack 43 is slidably connected to the housing, and a sliding direction of the energy storage rack 43 relative to the housing is parallel to a length direction of the pH meter 200 .

[0060] Optionally, the energy storage assembly 40 also includes an energy storage connector 44, which is provided with a receiving hole (not shown in the figure) for accommodating the probe 210. The pH meter 200 includes a connecting portion 220 and a limiting portion 230. The probe 210 and the limiting portion 230 are respectively arranged at both ends of the connecting portion 220. The probe 210 can be extended into the cleaning sleeve 10 through the receiving hole so that the limiting portion 230 is in contact with the energy storage connector 44, and drives the energy storage rack 43 to move along the length direction of the pH meter 200, and can cause the first elastic member 42 to be compressed and accumulate elastic potential energy.

[0061] With such a configuration, when the probe 210 is inserted into the cleaning sleeve 10 through the receiving hole, the first elastic member 42 is compressed to accumulate elastic potential energy.

[0062] The energy storage assembly 40 further includes a second elastic member 45 , which is connected to the energy storage rack 43 . The second elastic member 45 is used to apply an elastic force parallel to the length direction of the pH meter 200 to the energy storage rack 43 and / or the energy storage connector 44 .

[0063] With such a configuration, after the energy storage rack 43 moves along the length direction of the pH meter 200 , the energy storage rack 43 can be reset by the elastic force of the second elastic member 45 .

[0064] Specifically, the second elastic member 45 can be a spring or elastic rubber.

[0065] Optionally, the energy storage assembly 40 includes a third gear 46, a fourth gear 47 and a fifth gear 48, the third gear 46 is sleeved on a shaft connected to the first elastic member 42, the fourth gear 47 and the fifth gear 48 are jointly sleeved on another shaft, the third gear 46 and the fourth gear 47 are meshed with each other, and the fifth gear 48 is kneaded with the energy storage rack 43.

[0066] With such an arrangement, when the energy storage rack 43 and the energy storage gear 41 are far apart, the energy storage rack 43 can be moved so that the first elastic member 42 is compressed and elastic potential energy is accumulated.

[0067] Optionally, the cleaning device 100 further includes a shell (not shown in the figure), the cleaning sleeve 10 is slidably connected to the shell, and the sliding direction of the cleaning sleeve 10 relative to the shell is parallel to the length direction of the pH meter 200.

[0068] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 3 yes Figure 1 The top view of the cleaning device 100 is shown. Figure 4 yes Figure 1 A perspective view of a portion of the cleaning device 100 is shown.

[0069] The cleaning device 100 further includes a transmission assembly 30 , and the driving member 20 is transmission-connected to the cleaning sleeve 10 via the transmission assembly 30 .

[0070] By adopting the above solution, when the driving member 20 is far away from the cleaning sleeve 10 , the driving member 20 can still be controlled by the energy storage assembly 40 to drive the cleaning sleeve 10 to move back and forth along the length direction of the pH meter 200 .

[0071] Specifically, the transmission assembly 30 may include gears, belts, connecting rods, etc.

[0072] In this embodiment, the transmission assembly 30 includes a transmission connector 31, a transmission elastic member 32, and a cam 33. The transmission connector 31 is connected to the cleaning sleeve 10; the transmission elastic member 32 is connected to the transmission connector 31, and the transmission elastic member 32 is used to apply an elastic force parallel to the length direction of the pH meter 200 to the transmission connector 31. The end of the transmission connector 31 away from the cleaning sleeve 10 is connected to the cam 33, and the cam 33 is in transmission connection with the driving member 20. The energy storage assembly 40 is used to enable the driving member 20 to drive the driving cam 33 to rotate about the axis of the cam 33, thereby causing the transmission connector 31 to reciprocate along the length direction of the pH meter 200.

[0073] By adopting the above solution, the energy storage component 40 can accumulate energy by manually controlling the driving member 20 to drive the cam 33 to rotate around the axis of the cam 33, thereby causing the transmission connecting member 31 to move back and forth along the length direction of the pH meter 200, and the structure of the transmission component 30 is relatively simple.

[0074] It can be understood that the transmission connection member 31 and the cam 33 can form a cam-connecting rod mechanism.

[0075] Specifically, the transmission elastic member 32 can be a spring or elastic rubber. The transmission assembly 30 can be arranged in the housing, and the opposite ends of the transmission elastic member 32 are connected to the housing and the transmission connecting member 31 respectively.

[0076] For example, the driving member 20 includes a connecting shaft 21; the transmission assembly 30 includes a transmission shaft 34, a first gear 35 and a second gear 36, the first gear 35 and the cam 33 are fixedly mounted on the transmission shaft 34, the second gear 36 is mounted on the connecting shaft 21, and the first gear 35 and the second gear 36 are meshed.

[0077] With such an arrangement, the cam 33 can be driven to rotate around the axis of the cam 33 by simply rotating the connecting shaft 21 , thereby enabling the transmission connection between the cam 33 and the driving member 20 to be realized more conveniently.

[0078] Specifically, the connecting shaft 21 and the transmission shaft 34 are both rotatably connected to the housing.

[0079] Optionally, the driving member 20 includes a rotating portion 22 fixedly connected to the connecting shaft 21, the rotating portion 22 can rotate together with the connecting shaft 21, and the rotating portion 22 is located outside the housing. Such an arrangement can facilitate the rotation of the connecting shaft 21 through the rotating portion 22.

[0080] Please refer to Figures 1 to 4 In this embodiment, the second gear 36 can follow the driving member 20 to move along the length direction of the connecting shaft 21, so that the first gear 35 and the second gear 36 are disengaged.

[0081] By adopting the above solution, when there is no need to drive the cleaning sleeve 10 to reciprocate along the length direction of the pH meter 200, the first gear 35 and the second gear 36 can be disengaged.

[0082] The second gear 36 includes a main body 361 and an engaging portion 362 connected to each other. The main body 361 is sleeved on the connecting piece. The main body 361 rotates around the axis of the connecting shaft 21 so that the engaging portion 362 intermittently engages with the first gear 35 .

[0083] With such arrangement, the driving member 20 can be manually controlled to drive the main body 361 to rotate around the axis of the connecting shaft 21, so that the meshing portion 362 is intermittently meshed with the first gear 35, thereby causing the cam 33 to intermittently rotate around the axis of the cam 33, so that the transmission connecting member 31 and the cleaning sleeve 10 can intermittently reciprocate along the length direction of the pH meter 200, thereby being able to intermittently clean the probe 210 of the pH meter 200, that is, the probe 210 of the pH meter 200 can be cleaned at regular intervals.

[0084] For example, the second gear 36 can be a half gear, and the first gear 35 can be a full gear. The design makes the time interval between each engagement of the second gear 36 and the first gear 35 be 12 hours. The driving member 20 can be moved along the length direction of the connecting shaft 21 so that the second gear 36 and the first gear 35 are staggered in the meshing position and disengaged. At this time, by rotating the connecting shaft 21, the relative position of the teeth of the second gear 36 and the first gear 35 can be adjusted, that is, the time when the teeth of the second gear 36 start to mesh with the first gear 35 can be adjusted, thereby adjusting the cleaning time without adjusting the electrical structure.

[0085] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
