[0039] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0040] First, refer to Figures 1 - 13A brief description is given to the paint mist capture device 1000 according to the embodiment of the second aspect of the present utility model. The paint mist capture device 1000 includes a container 200 for storing water and an alarm device 100. The water stored in the container 200 is the circulating water during the operation of the paint mist capture device 1000. When the paint mist is captured into the water, the concentration of the water will gradually increase during long-term use. Here, the concentration refers to the concentration of paint residues, organic components in the paint mist, etc. The increase in the concentration of the water makes the quality of the water deteriorate. Therefore, the stored water in the container 200 needs to be treated or replaced with fresh water to enable the stable operation of the paint mist capture device 1000. The alarm device 100 is provided on the container 200 and is used to detect the liquid level and concentration of the liquid to be detected in the container 200.

[0041] Next, reference is made to Figures 1 - 13 describe the alarm device 100 according to the embodiment of the first aspect of the present utility model.

[0042] As Figures 1 - 13 shown, the alarm device 100 according to the embodiment of the first aspect of the present utility model includes: a fixing plate 11, a liquid level detection component, a concentration detection component, and an alarm component.

[0043] Specifically, the liquid level detection component is provided on the fixing plate 11 and is used to detect the liquid level of the liquid to be detected; the concentration detection component is provided on the fixing plate 11 and is used to detect the concentration of the liquid to be detected; the alarm component is provided on the fixing plate 11, and both the liquid level detection component and the concentration detection component are electrically connected to the alarm component.

[0044] In this embodiment, the liquid level detection component and the concentration detection component are provided. The liquid level detection component can detect the liquid level of the liquid to be detected, and the concentration detection component can detect the concentration of the liquid to be detected. Both the liquid level detection component and the concentration detection component are electrically connected to the alarm component. When the liquid level detection component detects that the liquid level exceeds the highest liquid level, the alarm component can issue a liquid level alarm, and when the concentration detection component detects that the concentration exceeds the standard, the alarm component can issue a concentration alarm. Thus, the liquid to be detected in the container 200 can be discharged or replaced in time, well avoiding risks such as liquid overflow and equipment damage caused by exceeding the liquid level or concentration standard, enabling the paint mist capture device 1000 to operate stably, reliably, and for a long time.

[0045] In this embodiment, the liquid level detection component, the concentration detection component, and the alarm component are all provided on the fixing plate 11, with a simple structure, enabling the liquid level detection component, the concentration detection component, and the alarm component to be integrated on the fixing plate 11. Thus, the overall alarm device 100 has good integration and a compact structure. When installing and arranging the alarm device 100, the liquid level detection component, the concentration detection component, and the alarm component can be integrally installed and fixed through the fixing plate 11, making the installation and arrangement of the alarm device 100 more convenient and easier.

[0046] According to the alarm device 100 of the embodiment of the present utility model, by providing a fixing plate 11, a liquid level detection component, a concentration detection component and an alarm component, the liquid level detection component, the concentration detection component and the alarm component are all arranged on the fixing plate 11, and both the liquid level detection component and the concentration detection component are electrically connected to the alarm component, which well integrates the liquid level detection and concentration detection functions and gives an alarm. The structure is simple, the integration is good, and the installation and arrangement are convenient.

[0047] In some embodiments of the present utility model, as Figure 1 shown, the liquid level detection component may include: a mounting plate 12, a first probe 14 and a second probe 15. The mounting plate 12 is connected to the fixing plate 11; both the first probe 14 and the second probe 15 extend in the up and down direction (such as Figure 1 the up and down direction shown) and are arranged at intervals in the first direction (such as Figure 1 the front and back direction shown). The first probe 14 and the second probe 15 are fixed on the mounting plate 12, and the first probe 14 and the second probe 15 cooperate with each other to detect the liquid level of the liquid.

[0048] In this embodiment, the mounting plate 12 is provided. The mounting plate 12 is connected to the fixing plate 11, and the first probe 14 and the second probe 15 are fixed on the mounting plate 12. The structure is simple and it is convenient to install and fix the first probe 14 and the second probe 15. The first probe 14 and the second probe 15 cooperate with each other to detect the liquid level of the liquid. Exemplarily, when the liquid level of the liquid to be detected rises and the rising liquid level reaches the lower ends of the first probe 14 and the second probe 15, the first probe 14 and the second probe 15 come into contact with water. Since water has conductivity, the first probe 14 and the second probe 15 can conduct the liquid level detection circuit where the first probe 14 and the second probe 15 are located through the liquid to be detected, so that the alarm component can give a liquid level warning when the liquid level detection circuit is conducted. Exemplarily, the height position where the lower ends of the first probe 14 and the second probe 15 are located can be set as needed, so that when the liquid level rises and contacts the first probe 14 and the second probe 15, the liquid level is at the highest liquid level.

[0049] In this embodiment, the first probe 14 and the second probe 15 are arranged to extend in the up and down direction and are arranged at intervals in the first direction. The structure is simple, the arrangement is convenient, and it is convenient for the first probe 14 and the second probe 15 to cooperate to detect the liquid level. Optionally, the lower end of the first probe 14 and the lower end of the second probe 15 can be at the same height, so that the first probe 14 and the second probe 15 can cooperate better, and the first probe 14 and the second probe 15 can stably contact the water liquid for liquid level detection.

[0050] In one embodiment of the present utility model, referring to Figure 1 and Figure 2As shown, the position of the mounting plate 12 relative to the fixed plate 11 is adjustable in the up and down direction.

[0051] In this embodiment, the mounting plate 12 is set to be adjustable relative to the fixed plate 11 in the up and down direction, so that the first probe 14 and the second probe 15 can change their height positions with the movement of the mounting plate 12 according to the needs of liquid level detection, enabling the liquid level detection component to meet the needs of different liquid level detections, and thus making the liquid level detection component more convenient and flexible to use.

[0052] In some examples of the present utility model, such as Figure 1 and Figure 2 As shown, the mounting plate 12 may be provided with adjustment holes 121. The adjustment holes 121 extend in the up and down direction and penetrate the mounting plate 12 in the thickness direction of the mounting plate 12. The liquid level detection component further includes a fastener 13. The mounting plate 12 is fixedly connected to the fixed plate 11 through the fastener 13 passing through the adjustment holes 121.

[0053] In this embodiment, the adjustment holes 121 are provided on the mounting plate 12. The adjustment holes 121 extend in the up and down direction. The fastener 13 passes through the adjustment holes 121 to fix the mounting plate 12 to the fixed plate 11. The structure is simple, the fixing is convenient and reliable. The mounting plate 12 can adjust its relative position with the fixed plate 11 in the up and down direction as needed. The mounting plate 12 moves up and down relative to the fastener 13. The adjustment holes 121 extending in the up and down direction can well cooperate with the change of the relative position of the fastener 13 and the mounting plate 12 in the up and down direction, enabling the fastener 13 to fixedly connect the mounting plate 12 and the fixed plate 11 stably and reliably.

[0054] In an example of the present utility model, referring to Figure 2 and Figure 6 As shown, the fixed plate 11 may be provided with mating holes 112. The fastener 13 passes through the adjustment holes 121 and is threadedly connected to the mating holes 112. In this embodiment, the mating holes 112 are provided on the fixed plate 11, so that after the fastener 13 passes through the adjustment holes 121, it can be connected and fixed to the fixed plate 11 through the mating holes 112, thereby fastening the mounting plate 12 to the fixed plate 11. The structure is simple and can well meet the assembly needs of the mounting plate 12 and the fixed plate 11.

[0055] In an embodiment of the present utility model, such as Figure 1 As shown, the concentration detection component may include: a concentration sensor 24 and a liquid sampling brush 22. The concentration sensor 24 is connected to the mounting plate 12. The concentration sensor 24 has a detection portion 241. The concentration sensor 24 is electrically connected to the alarm component. The liquid sampling brush 22 is provided on the mounting plate 12. The liquid sampling brush 22 is movable between a liquid sampling position and a detection position. At the liquid sampling position, the liquid sampling brush 22 is adapted to collect the liquid to be detected. At the detection position, the liquid sampling brush 22 contacts the detection portion 241 so that the concentration sensor 24 contacts the liquid to be detected.

[0056] In this embodiment, the concentration detection assembly is provided with a concentration sensor 24 and a liquid-taking brush 22. When the concentration detection assembly performs concentration detection, the liquid-taking brush 22 collects the liquid to be detected at the liquid-taking position. The liquid-taking brush 22 moves from the liquid-taking position to the detection position, so that the collected liquid to be detected contacts the detection part 241 of the concentration sensor 24, so that the concentration sensor 24 can detect the concentration of the liquid to be detected. When the concentration detection assembly detects that the concentration exceeds the standard, the alarm assembly issues a concentration alarm, so that the water liquid in the container 200 can be processed in time or new water can be replaced, so that the paint mist capture device 1000 can operate stably.

[0057] In this embodiment, the concentration sensor 24 is connected to the mounting plate 12, and the liquid-taking brush 22 is arranged on the mounting plate 12. The structure is simple, which can well integrate and arrange the concentration detection assembly and the liquid level detection assembly, so that the overall structure of the alarm device 100 is more compact and the integration is better, making the alarm device 100 more convenient to assemble and more convenient and easy to arrange on the container 200.

[0058] In some examples of the present utility model, referring to Figure 1 As shown, the concentration detection assembly may further include a driving motor 21. The driving motor 21 is fixed on the mounting plate 12, and the driving motor 21 is in transmission connection with the liquid-taking brush 22. The driving motor 21 drives the liquid-taking brush 22 to rotate between the liquid-taking position and the detection position. Among them, the driving motor 21 is configured to be operable after the first probe 14 and the second probe 15 are conducted.

[0059] In this embodiment, the driving motor 21 is arranged in the concentration detection assembly. The driving motor 21 drives the liquid-taking brush 22 to rotate between the liquid-taking position and the detection position. The structure is simple, the driving is convenient and reliable, so that the liquid-taking brush 22 can move between the liquid-taking position and the detection position stably and reliably, so that the concentration detection assembly can stably detect the concentration of the liquid to be detected.

[0060] The driving motor 21 in this embodiment is configured to operate after the first probe 14 and the second probe 15 are conducted. Exemplarily, when the alarm device 100 is operating, when the liquid level in the container 200 rises and contacts the first probe 14 and the second probe 15, the water liquid conducts the circuit where the first probe 14 and the second probe 15 are located, and the alarm assembly issues a liquid level alarm. At this time, the driving motor 21 operates, and the concentration detection assembly detects the concentration of the liquid to be detected. When the concentration exceeds the standard, the alarm assembly issues a concentration alarm.

[0061] It can be understood that during the operation of the paint mist collection device, the concentration of the liquid to be detected in the container 200 often does not easily exceed the standard. In this embodiment, the driving motor 21 is set to operate after the first probe 14 and the second probe 15 are conducted, so that the concentration detection component performs concentration detection when the liquid level detection component detects that the water level exceeds the standard. This can reduce the operation frequency of the concentration detection component, avoid the frequent operation of the driving rod motor, thereby reducing the power consumption when the alarm device 100 operates and lowering the operation cost of the alarm device 100.

[0062] In an example of the present utility model, referring to Figure 1 and Figure 8 As shown, the liquid sampling brush 22 may include: a brush rod 221 and a brush body 222. One end of the brush rod 221 is in transmission connection with the driving motor 21, and the other end of the brush rod 221 is provided with the brush body 222. At the liquid sampling position, the liquid sampling brush 22 extends in the up and down direction, and the lower end of the brush body 222 extends downward beyond the lower edges of the first probe 14 and the second probe 15.

[0063] In this embodiment, the liquid sampling brush 22 is provided with a brush rod 221 and a brush body 222, which has a simple structure and is convenient for assembly. When the driving motor 21 operates, it drives the brush rod 221 to rotate, so that the brush body 222 can rotate to the detection position after collecting the liquid to be detected at the liquid sampling position and contact the detection part 241. At the liquid sampling position, in this embodiment, the lower end of the brush body 222 is set to extend downward beyond the lower edges of the first probe 14 and the second probe 15. When the first probe 14 and the second probe 15 are conducted with the liquid to be detected, the brush body 222 can stably and reliably extend into the liquid to be detected to collect the liquid, so that the concentration sensor 24 can stably obtain the liquid to be detected for concentration detection, thereby making the operation of the concentration detection component more stable.

[0064] In an example of the present utility model, as Figure 1 and Figure 10 shown, the concentration detection component may further include a support rod 23. The support rod 23 extends in the first direction. One end of the support rod 23 is connected to the mounting plate 12, and the concentration sensor 24 is fixed to the other end of the support rod 23.

[0065] In this embodiment, the support rod 23 is provided to fix the concentration transmitter on the mounting plate 12, which has a simple structure and is convenient for fixing, enabling the concentration sensor 24 to cooperate well with the liquid sampling brush 22 for concentration detection.

[0066] In an example of the present utility model, as Figure 1 and Figure 11As shown, a first limiting member 25 and a second limiting member 26 may be provided on the mounting plate 12. The liquid taking brush 22 is disposed between the first limiting member 25 and the second limiting member 26. In the liquid taking position, the liquid taking brush 22 abuts against the first limiting member 25. In the detection position, the liquid taking brush 22 abuts against the second limiting member 26.

[0067] In this embodiment, the first limiting member 25 and the second limiting member 26 are provided on the mounting plate 12, so that the liquid taking brush 22 can stably rotate between the liquid taking position and the detection position under the limitation of the first limiting member 25 and the second limiting member 26, and the liquid taking brush 22 can stably rotate to the liquid taking position and the detection position, so that the concentration detection assembly can stably collect the liquid to be detected for concentration detection. Optionally, the first limiting member 25 may be a limiting rod, and the second limiting member 26 may also be a limiting rod.

[0068] In some embodiments of the present utility model, such as Figure 2 and Figure 6 As shown, the fixing plate 11 may be formed with a mounting groove 111. The opening of the mounting groove 111 faces downward and penetrates the fixing plate 11 in the first direction (such as Figure 1 the front-back direction shown). The fixing plate 11 is adapted to be clamped to the edge of the container 200 through the mounting groove 111.

[0069] In this embodiment, the fixing plate 11 is provided with the mounting groove 111 with the opening facing downward, and the mounting groove 111 penetrates the fixing plate 11 in the first direction, so that the mounting groove 111 can be well matched with the edge of the container 200, so that the fixing plate 11 can be easily clamped and fixed to the edge of the container 200. The structure of the mounting groove 111 is simple, and it is clamped and fixed to the edge of the container 200, and the assembly is convenient, making it very convenient for the alarm device 100 to be installed and arranged with the container 200.

[0070] In an embodiment of the present utility model, referring to Figure 1 and Figure 6 As shown, the fixing plate 11 may include: a first plate portion, a second plate portion, and a third plate portion. The first plate portion is horizontally arranged, and the second plate portion and the third plate portion both extend in the up-down direction and the upper ends are respectively connected to both ends of the first plate portion in the second direction (such as Figure 1 the left-right direction shown). The first plate portion, the second plate portion, and the third plate portion cooperate to define the mounting groove 111. The alarm assembly is disposed on the first plate portion, and the mounting plate 12 is fixedly connected to the third plate portion.

[0071] In this embodiment, the fixing plate 11 is provided with a first plate portion, a second plate portion and a third plate portion which cooperate to define an installation groove 111. The structure is simple and can provide a good installation position for the liquid level detection component and the alarm component, making it more convenient to assemble the alarm device 100. Optionally, the fixing plate 11 can be an integral part, which can facilitate the processing of the fixing plate 11 and improve the overall structural strength, enabling the fixing plate 11 to stably and reliably support and fix the liquid level detection component and the like, and making the fixing plate 11 more stable and reliable when clamped and fixed on the container 200.

[0072] In some examples of the present utility model, referring to Figure 1 and Figure 6 as shown, the length dimension of the second plate portion in the up-down direction can be smaller than the length dimension of the third plate portion in the up-down direction. This can make it more convenient and easy to install and disassemble the fixing plate 11 when it is clamped and fixed on the edge of the container 200.

[0073] In some embodiments of the present utility model, referring to Figure 1 as shown, the alarm component can include: an electric control box 31 and a warning light 32.

[0074] In this embodiment, the alarm component includes an electric control box 31 and a warning light 32.
