Embodiments of the present disclosure provide a liquid detector. Referring to fig. 1, the liquid detector includes a housing 5, a first detector 4, and a power supply structure 8.

In some embodiments, the housing 5 includes a housing body 51 and a handle 52. Illustratively, the housing body 51 includes an upper housing 51a and a lower housing 51b, and the upper housing 51a and the lower housing 51b are fixedly connected (e.g., bolted, clamped, etc.). Also illustratively, the handle 52 includes an upper handle and a lower handle. The upper handle and the lower handle are buckled together. Further illustratively, the handle 52 is integrally formed with the housing body 51. In some examples, the upper handle is integrally formed with the upper housing 51a and the lower handle is integrally formed with the lower housing 51 b. Also illustratively, the interface of the handle 52 with the housing body 51 may be smoothly curved so that the operator's fingers rest comfortably on the interface.

The housing 5 has a mounting window 53. The mounting window 53 is used for mounting the first detector 4. For example, the lower housing 5 has a mounting window 53 thereon. In some examples, the housing 5 also has a receiving cavity, which may be understood as an internal cavity of the housing 5.

The first detector 4 is used for detecting the liquid in the metal bottle tank. The first detector 4 includes a heating tip 42 and a first switch 43 coupled.

The first switch 43 is an electronic device configured to open or close a circuit coupled thereto. For example, the first switch 43 may be a contact switch (also referred to as a tact switch), that is, in case of pressing the contact switch, the contact switch can conduct a circuit coupled thereto; when the contact switch is released, the contact switch is reset (the contact switch is reset by the internal metal elastic sheet), and the circuit coupled with the contact switch is disconnected. The circuit coupled thereto is, for example, the circuit of the first detector 4.

The first detector 4 can detect the liquid in the metal bottle by using the heating principle. Illustratively, the heating tip 42 may have a heating function. For example, the heating probe 42 includes a heat conducting sheet (the material of the heat conducting sheet may be a heat conducting material, for example, the heat conducting material may be a metal, etc.) and a heating wire, and the heating wire is disposed in the heat conducting sheet. In some examples, the heating tip 42 may also have the function of detecting temperature. For example, the heater probe 42 also includes a temperature detector (which may also be referred to as a temperature sensor in some embodiments) disposed within the thermally conductive sheet. In this way, the heating tip 42 can be used to heat the metal bottle; the temperature sensor can also be used for detecting the temperature change of the liquid in the metal bottle tank before and after heating.

The heating tip 42 and the first switch 43 are both fixedly provided on the housing 5 at the mounting window 53, the first switch 43 has an activation portion 43a, and the mounting window 53 exposes the heating tip 42 and the activation portion 43a. Here, the first switch 43 may be configured to be turned on when the trigger portion 43a is pressed, the first switch 43 may be turned off when the pressing is removed, or the first switch 43 may be turned on or off under the control of another control switch or key electrically connected thereto. The trigger 43a may also be used to detect whether a container is to be detected, e.g., if there is a container contacting or squeezing the trigger 43a, then there is a container to be detected, and if there is no container contacting or squeezing the trigger 43a, then there is no container to be detected.

In some examples, the trigger portion 43a protrudes from a side of the heating tip 42 near the outside of the housing 5. For example, the first switch 43 also has a pin that is coupled to the first switch 43. In the open state of the first switch 43, the first detector 4 is used to detect the liquid in the container, and the container is in contact with the trigger during the liquid detection.

In a preferred embodiment, for example, the first switch may be configured to be opened when the trigger portion is pressed, that is, the operator holds the metal bottle by one hand and contacts with the first detector 4 (in the embodiment of the present application, it is considered that a certain pressing force is generated when the container contacts with the trigger, and an external force generates an urging force on the container to increase the pressing force of the container on the trigger), and the first detector 4 may be turned on to detect the liquid in the metal bottle, so that the operator may not need to press the detection switch for controlling the first switch to be in the open state for a long time, thereby improving the operation performance and providing higher convenience in use.

Specifically, the heating tip 42 and the first switch 43 are fixedly provided on the housing 5 at the mounting window 53, and both can be exposed through the mounting window 53 (e.g., at least a portion of each of both protrudes from the mounting window 53 to the outside of the housing 5). In one embodiment, the first switch 43 may be turned on by pressing the trigger 43a so that the first detector 4 performs the liquid detection function, i.e., the trigger 43a of the first switch 43 may be contacted with the metal can so that the first switch 43 is turned on, thereby turning on the heating tip 42; meanwhile, as the heating probe 42 and the first switch 43 are exposed by the mounting window 53, the heating probe 42 and the first switch 43 are relatively close to each other, and the metal bottle can is contacted with the heating probe 42 under the condition that the metal bottle can is contacted with the trigger part 43a, the heating probe 42 is heated, and the first detector 4 is used for detecting whether the liquid in the metal bottle can is dangerous liquid or safe liquid.

In some examples, at least a portion of the heating tip 42 and at least a portion of the first switch 43 extend from the mounting window 53, wherein at least a portion of the first switch 43 is not lower (e.g., flush with, e.g., higher than) at least a portion of the heating tip 42 in a direction perpendicular to the heating tip 42 (i.e., a front-to-back direction), which makes it easier to reach the heating tip 42 in the event that the first switch 43 is touched.

Referring to fig. 2, for example, a part of the first switch 43 is located below the heating tip 42, and the triggering portions 43a are respectively located at the sides of the heating tip 42, that is, the heating tip is located between two triggering portions 43a, compared to a case where the triggering portions 43a are also located below the heating tip 42, frequent triggering of the heating tip 42 can be avoided, which helps to prolong the service life of the heating tip 42.

In some examples, the first detector 4 further includes a device housing 41, the device housing 41 being secured to the housing 5 at a mounting window 53, the mounting window 53 exposing the device housing 41. The heating tip 42 and the first switch 43 are both fixedly provided on the device case 41.

The first detector 4 further includes a first rib 44 and a second rib 45, the first rib 44 and the second rib 45 both protrude from one side of the heating probe 42 close to the outside of the housing 5, and the trigger portion 43a is located between the first rib 44 and the second rib 45. Thus, the metal bottle can is positioned between the first rib 44 and the second rib 45 and contacts the trigger part 43a of the first switch 43 to open the first switch 43, so that the situation that the first switch 43 is not touched can be reduced; meanwhile, the metal bottle can is limited between the first convex rib 44 and the second convex rib 45 (see fig. 2, namely, the metal bottle can is horizontally contacted with the heating probe 42), so that the metal bottle can slide on the heating probe 42 and the first switch 43 to play a role in limiting, and the condition of inaccurate detection can be avoided.

In some examples, the device case 41 has a first rib 44 and a second rib 45. In some examples, the side of the first rib 44 and the second rib 45 away from the outside of the housing 5 is flush with the side of the trigger portion 43a away from the outside of the housing 5.

Illustratively, the number of the first ribs 44 and the second ribs 45 is the same as the number of the triggering portions 43a. For example, in the above embodiment, the number of the triggering portions 43a, the number of the first ribs 44, and the number of the second ribs 45 may each be one. Of course, the number of the triggering portions 43a, the number of the first ribs 44, and the number of the second ribs 45 are not limited to one, and for example, the number of the triggering portions 43a, the number of the first ribs 44, and the number of the second ribs 45 may be two.

In some examples, referring to fig. 2, the two triggering portions 43a, the first ribs 44, and the second ribs 45 are each two in number and are respectively located on both sides (e.g., the left and right sides as viewed in fig. 2) of the heating tip 42. In this way, the metal detection bottle can vertically contact the heating tip 42 and the trigger 43a.

In some examples, the detection principle of the first detector 4 may be: when the metal bottle contacts the first switch 43, the first switch 43 is turned on, the first switch 43 which is turned on turns on the heating probe 42, and the heating probe 42 contacts the metal bottle, the heating probe 42 heats up, and the metal of the metal bottle has heat transfer, so that the heating probe 42 heats the liquid in the metal bottle, after a period of time (for example, within 3S, for example, within 5S), the temperature difference of the liquid in the metal container (for example, the temperature difference can be measured by using a temperature sensor in the heating probe 42) can be measured. The temperature difference is compared with a determination value (which may also be referred to as a predetermined value or a threshold value) of an existing database (for example, a database of hazardous liquids and non-hazardous liquids), and when the detected temperature difference is greater than the determination value, it is indicated that the liquid is a hazardous liquid, otherwise, it is a non-hazardous liquid. It should be noted that the first detector 4 in this embodiment can be used to detect whether the liquid in the metal container is a dangerous liquid or a non-dangerous liquid, and the liquid cannot be accurately obtained as a specific solution.

In some examples, referring to fig. 3, the liquid detector further includes a protective cover k, and the protective cover k is buckled on the first detector 4, so that the protective cover k is buckled on the first detector 4 to avoid collision with the first switch 43 and open the first switch 43 when the first detector 4 is not used; and simultaneously, the pollution on the first detector 4 can be effectively reduced.

In some embodiments, with continued reference to FIG. 3, the liquid detector further comprises a second detector 3 for detecting the liquid in the non-metallic canister. The second detector 3 is fixed on the housing 5; for example, the first detector 4 may be fixed to a side (e.g., right side) of the housing 5, and the second detector 3 may be fixed to the front of the housing 5.

In some examples, the second detector 3 may be a detector capable of emitting microwaves or a detector that can emit electromagnetic waves. The detection of the liquid in the non-metallic container is performed using microwaves or electromagnetic waves. Further, since the second detector 3 can continuously emit microwaves, electromagnetic waves, or the like, the second detector 3 can continuously detect the liquid in the non-metal container. The second detector 3 can be used for detecting whether the liquid in the non-metal container belongs to dangerous liquid or non-dangerous liquid.

With continued reference to fig. 3, the power supply structure 8 is configured to provide a power supply voltage to the liquid detector. In some examples, the power supply structure 8 is configured to provide a supply voltage to the first detector 4. That is, the power supply structure 8 may be coupled with the first detector 4. In some examples, the power supply arrangement 8 also provides a power supply voltage to other electronics of the liquid detector, such as the second detector 3, as well as electronics present below (e.g., display screen, controller, indicator lights, etc.).

The power supply structure 8 is detachably clipped in the hand casing 5. So for power structure 8 can be replaced in a flexible way, even the electric energy is not enough in current power structure 8, can in time carry out the electric energy through the dismantlement mode and supply, and is less to the influence of liquid detection instrument when normal work like this, and the time that needs to interrupt liquid detection promptly is shorter, has higher use convenience. In some examples, the handle 52 has a mounting cavity 52a, e.g., the upper and lower handles snap together, forming the mounting cavity 52a between the upper and lower handles. Wherein, the power supply structure 8 can be installed in the installation cavity 52a and be clamped in the installation cavity 52a.

In some embodiments, referring to fig. 4, 5 and 6, the power supply structure 8 includes a seat 81, a battery 83 and a clasp 82. The battery 83 is fixed to the seat 81. For example, the battery 83 and the seat 81 may be cylindrical, and the battery 83 and the seat 81 may be coaxially fixed. In some examples, battery 83 is mounted within mounting cavity 52a. For example, the battery 83 may be a rechargeable battery 83.

The housing 81 has an installation groove 811. The clip 82 includes a pressing portion 821 and a clip portion 822, the pressing portion 821 is fixedly connected to the clip portion 822, and the pressing portion 821 is elastically provided in the mounting groove 811. In some examples, the power supply structure 8 further includes an elastic member 84, and the pressing portion 821 is elastically disposed in the mounting groove 811 by the elastic member 84. For example, the elastic member 84 may be a metal leaf spring (e.g., a spring steel sheet). The clamping portion 822 extends from the mounting groove 811 and extends into the handle 52, and the clamping portion 822 is clamped with the handle 52. In some examples, the mounting groove 811 has two notches, a first notch and a second notch. Wherein the first notch exposes the pressing portion 821. The catching portion 822 protrudes from the second notch of the mounting groove 811 and extends into the handle 52.

In some examples, the latch portion 822 is provided with a latch, and the handle 52 is provided with a reverse block, and the latch and the reverse block are cooperatively arranged. That is, after the battery 83 is mounted in the mounting cavity 52a, the latch is snapped onto the inverted block so that the base is coupled to the handle 52.

In some embodiments, referring to fig. 7, the liquid detector further comprises a charger. The charger is configured to charge the power supply structure 8. The charger has a charging slot into which the power supply arrangement 8 is plugged. For example, a battery is inserted into a charging slot to charge the battery. In some examples, the charging principle of the charger may be selected according to the type of battery; for example, the battery is a storage battery, and the charger is a charger for charging the storage battery, so the principle of the charger is not limited in this example, and is not described again. In some examples, the number of charging slots may be at least one (e.g., one, and for example, multiple), such that the charger may charge multiple power supply structures 8.

In some examples, the number of the power structures 8 is two (which can be referred to as a first power structure 8 and a second power structure 8), wherein the first power structure 8 is clamped on the handle 52 to provide a power voltage for the liquid detector; the second power supply arrangement 8 may continue to be charged (e.g. by a charger) as a backup power supply. Therefore, when the first power supply structure 8 is not powered, the first power supply structure is taken down from the handle 52, and the charged second power supply structure 8 is clamped in the handle 52 for use, so that the liquid detector can continue to work. In addition, compared with a liquid detector which is charged by adopting a charging wire, the liquid detector which adopts the charging wire has a limited operation space due to the limitation of the charging wire, and the liquid detector of the example has a larger operation space.

In some embodiments, referring to fig. 8, the handle 52 has a plurality (e.g., two, three, four, etc.) of grooves 52b located on a surface of the handle 52. The groove wall of the groove 52b is provided with anti-slip lines, so that the friction force between fingers and the groove 52b can be increased, and the handle 52 can be better held. Wherein the anti-skid lines can be inclined and convex lines.

In some embodiments, referring to fig. 9 and 10, the liquid detector further includes a second switch 9 and a detection button 6.

The second switch 9 is an electronic device configured to open or close a circuit coupled thereto. In some examples, the second switch 9 may be a contact switch, which may be referred to in relation to the contact switch above.

The second switch 9 is fixedly arranged (e.g. bolted) in the housing 5 (e.g. in the receiving cavity). The first switch 43, the second switch 9 and the first detector 4 are connected in series. The detection button 6 is provided on the housing 5 and configured to control the second switch 9 to be turned on or off. Thus, when the metal bottle can contacts the first switch 43, the first switch 43 is opened; simultaneously pressing the detection button 6, the detection button 6 contacts the second switch 9, so that the second switch 9 is turned on, and in case the first switch 43 and the second switch 9 are turned on simultaneously, the first detector 4 is turned on, i.e. the first detector 4 can perform the liquid detection function. In the case where the first switch 43 or the second switch 9 is turned off, the first detector 4 is turned off. Thus, the first detector 4 is not turned on even when the first switch 43 or the second switch 9 is not touched. Namely, the cooperation of the first switch 43 and the second switch 9 can play a role of preventing accidental touch; therefore, the first detector 4 can not be started without touching the first switch 43 or the second switch 9, namely, the phenomenon that the first detector 4 is frequently started possibly is avoided, and the service life of the first detector 4 is effectively prolonged.

In some examples, the second switch 9 may be coupled to the second detector 3, such that the second detector 3 may be controlled to be turned on or off by the second switch 9.

Referring to fig. 10, the detection button 6 includes a rotation shaft 63, a trigger 61, and a reset member 62. The rotating shaft 63 is fixedly arranged in the accommodating cavity.

The trigger 61 is rotatably arranged on the rotating shaft 63; for example, the trigger 61 is provided with a through hole through which the trigger 61 is rotatably provided on the rotary shaft 63. In some examples, trigger 61 may be shaped like a ski so that it fits the operator's fingers when pressed, making it more comfortable to use. In some examples, the trigger 61 has opposing pressing and contact ends, the pressing end may be an end face of the trigger 61 pressed by the operator; the contact end is the end surface of the trigger 61 contacting the second switch 9, and the through hole is positioned between the pressing end and the contact end, so that the distance from the pressing end to the rotating shaft 63 is larger than the distance from the rotating shaft 63 to the contact end by utilizing the lever principle, and the trigger 61 is pressed more laborsavingly. In some examples, the housing 5 is opened with a through slot, the trigger 61 is rotatably connected to the rotating shaft 63 through the through slot, and a portion of the trigger 61 is exposed from the through slot. Wherein the portion of the trigger 61 that exposes the through slot may be a pressing end.

The reset member 62 has an initial state and a reset state. The initial state may be understood as a state in which the restoring member 62 does not have a restoring force (e.g., a torsion force or an elastic force). The reset state may be understood to be a condition in which the reset member 62 has a restoring force. The reset piece 62 is sleeved on the rotating shaft 63, and the reset piece 62 is fixedly connected with the trigger 61 and the shell 5; for example, the return member 62 may be a return spring, which is sleeved on the rotating shaft 63, and both ends of the return spring are fixed to the trigger 61 and the housing 5, respectively.

The principle of the test button 6 may be:

when the trigger 61 is not pulled, the reset piece 62 is in an initial state, and the second switch 9 is closed; that is, in the case where the trigger 61 is not pulled, the restoring member 62 has no restoring force (e.g., torsion or elastic force), and the trigger 61 does not contact the second switch 9, so that the second switch 9 opens the circuit of the detector. As the trigger 61 is pulled, the second switch 9 is opened by the trigger 61, and the reset member 62 is switched from the initial state to the reset state, so that the trigger 61 can be reset. That is, as the trigger 61 is pulled, the trigger 61 contacts the second switch 9 (indicating that the trigger 61 has opened the second switch 9) so that the second switch 9 turns on the circuit of the detector; at this time, the restoring member 62 has a restoring force, and when the trigger 61 is released, the trigger 61 is restored to a state in which the trigger 61 is not pulled by the restoring force of the restoring member 62.

In order to ensure that the trigger 61 can be accurately restored to the condition that the trigger 61 is not pulled under the condition of depending on the torsion or the elasticity of the resetting piece 62, the detection button 6 further comprises a limiting part 64. The stopper 64 is provided in the housing 5 so as to be separated from or in contact with the trigger 61. Thus, when the trigger 61 contacts the stopper portion 64, the stopper portion 64 restricts the rotation of the trigger 61.

Wherein, the trigger 61 can contact with the limit part 64 under the condition that the trigger 61 is not pulled. In this case, in some examples, the restoring member 62 may not have a torsion force or an elastic force. In other examples, the restoring member 62 may have a smaller torsion or spring force, but the torsion or spring force is smaller than the torsion or spring force of the restoring member 62 in the restoring state. As the trigger 61 is pulled, the trigger 61 is separated from the stopper portion 64.

In a possible implementation, the trigger 61 is provided with a projection 611, and the position-limiting portion 64 is also a projection, but the two are arranged convexly opposite to each other, and the projection 611 is used in cooperation with the position-limiting portion 64. For example, the projection 611 is located at the upper part of the position-limiting part 64, and there is a facing area between the projection 611 and the position-limiting part 64, and the facing area can be understood as the area where the projection 611 and the position-limiting part 64 intersect when they are in contact. Thus, when the trigger 61 is pressed, the projection 611 rotates upward with the trigger 61, and the projection 611 is separated from the stopper 64.

In some embodiments, referring to fig. 11, the liquid detector further includes a display assembly 2 and a first buffer member 1.

The display unit 2 has a display surface, which is a surface on which an image is displayed. The display component 2 may be some device capable of displaying images, for example, the display component 2 may be a display screen; also for example, the display assembly 2 may include a display screen and other structures. In some examples, the plurality of grooves 52b are disposed opposite to the plane of the display surface, which can be understood as the grooves 52b are below and the display surface is above. Thus, when the operator holds the handle 52, the fingers are positioned in the recesses 52b and the display screen 22 is positioned above for viewing by the operator.

The housing 5 has a display window 5a, and the display window 5a is communicated with the accommodating cavity. In some examples, the shape of the display window 5a may be designed according to the shape of the display surface. For example, the display surface is rectangular, and the display window 5a is also rectangular in shape as the display window 5a. For example, the display surface is circular, and the display window 5a is also rectangular and circular. In other examples, the shape of the display window 5a may be different from the shape of the display surface, for example, the display window 5a may be rectangular and the display surface may be circular.

The display component 2 is arranged in the accommodating cavity; for example, the display module 2 may be hermetically and fixedly disposed within the housing 5. The display window 5a exposes the display surface; the image displayed on the display surface can be viewed through the display window 5a, and the display surface can also be touched.

The first cushion member 1 is disposed on the housing 5, and surrounds the display window 5a. At least a part of the first cushion member 1 protrudes from the display surface toward the outside of the case 5. The material of the first cushioning element 1 may be a cushioning material, for example, the cushioning material may be a thermoplastic polyurethane elastomer (also called thermoplastic polyurethane rubber, abbreviated to TPU).

Exemplarily, the first buffer 1 may have an elongated structure. In some examples, the strip structure may surround the display window 5a and protrude from the display surface all towards the outside of the housing 5, in which case the strip structure may form a closed structure (e.g. rectangular or circular), wherein the shape of the closed structure may be the same as the shape of the display window 5a. In other examples, a portion of the elongated structure (e.g., the portion may be at least one-half of the perimeter of the display window 5 a) may surround the display window 5a and protrude from the display surface toward the outside of the housing 5; that is, the strip structure may constitute an unsealed structure, wherein the perimeter of the unsealed structure is at least one-half of the perimeter of the display window 5a.

Further exemplarily, the first buffer 1 may also be a plurality of block structures. In some examples, the plurality of block structures may be discretely (i.e., with gaps therebetween) disposed on the housing 5, and the plurality of block structures are disposed around the display window 5a, and all of the plurality of block structures protrude from the display surface toward the outside of the housing 5. In other examples, the plurality of block structures may be discretely (i.e., with gaps therebetween) disposed on the housing 5, and a circumference formed by the plurality of block structures is at least one-half of a circumference of the display window 5a, wherein the plurality of block structures protrude from the display surface toward the outside of the housing 5.

Since the first buffer member 1 is protruded from the display surface, that is, a certain distance (referred to as a safety distance) exists between the first buffer member 1 and the display surface. Then, after the liquid detector receives the collision or falls to the ground, the first buffer member 1 contacts with the ground or the collision object, thereby playing a role of buffering. During the contact process, the safety distance is reduced and does not disappear; that is to say there is the safe distance all the time between first bolster 1 and the display surface, and like this, guarantee that the display surface can not direct contact ground or collision object to the effectual condition of receiving the breakage of display module 2 (including display screen 22 at least) has been avoided. And further, the problem that the display screen 22 is easy to break after the liquid detector falls to the ground or collides with an object is solved.

In some embodiments, the housing 5 includes a mounting panel M and a boss 55.

The display window 5a is opened in the mounting panel M. The mounting panel M may be understood as a plane or a curved surface or the like for mounting the display module 2. The installation panel M may also be provided with keys (e.g., an on/off key, a selection key, a function key, etc.). In some examples, the upper housing 51a has a mounting panel M. The mounting panel M may be, for example, an upper surface (i.e., a top surface) of the upper case 51 a.

The projection 55 is provided around the mounting panel M and projects from the mounting panel M toward the outside of the housing 5. The first cushion member 1 is disposed on a side of the projection 55 away from the plane of the display surface. The plane of the display surface can be understood as an infinite extension plane of the display surface. Thus, the protrusion 55 is further disposed between the first buffer member 1 and the display surface, so that the safety distance between the first buffer member 1 and the display surface is increased, and the display surface is protected. The projections 55 can also be used for mounting the first cushioning element 1, for example the first cushioning element 1 can be fixedly connected to the projections 55.

The projections 55 may be ribs. The projection 55 is disposed on the mounting plate surface around the circumference. For example, the rib is arranged on the upper surface of the mounting plate surface around the circumference.

In some embodiments, referring to fig. 12, the display assembly 2 includes a display screen 22, a stationary backplate 24, and a second buffer 23.

The display screen 22 has opposing display and non-display sides. One side of the display surface is a display side, and one side of the non-display surface is a non-display side, i.e., the display side and the non-display side are opposite. The display surface of the display screen 22 may be the display surface of the display module 2. In some examples, the display 22 may be a liquid crystal display 22. The liquid crystal display 22 is, for example, a liquid crystal display 22 of a touch type (e.g., a liquid crystal display 22 of a capacitance type).

The fixed back plate 24 is disposed on the non-display side of the display screen 22 and is fixedly connected to the housing 5. The second cushion member 23 is disposed between the stationary backplate 24 and the display screen 22.

The fixing back plate 24 may be fixed in the accommodating cavity of the housing 5 by a connecting member such as a bolt, so as to firmly mount the display screen 22 in the accommodating cavity of the housing 5. The second buffer 23 may be a buffer material, which may be a buffer foam, for example. The second buffer member 23 may be fixed between the non-display side of the display screen 22 and the fixed back plate 24 by means of gluing or the like. When the liquid detector is impacted, the second buffer member 23 plays a role of buffering, and the collision between the display screen 22 and the fixed back plate 24 is reduced.

The second cushion member 23 has a hollow portion 23a. Illustratively, in a direction perpendicular to the display surface, there is an overlapping region between the projection of the display window 5a on the second buffer 23 and the hollow portion 23a. It can be understood that the hollow portion 23a and the display window 5a have the same hollow position in the direction perpendicular to the display surface. The cutout 23a may be designed according to the non-display side of the display screen 22. In some examples, the display screen 22 includes electronic components and connecting lines between coupled electronic components, wherein portions of the electronic components and connecting lines are located on a non-display side of the display screen 22; then, when the second buffer 23 is fixed on the non-display surface of the display screen 22 (for example, the second buffer 23 is fixed on the frame of the non-display surface of the display screen 22), the part of the electronic components and the connecting wires can be located in the hollow portion 23a, so that the part of the electronic components and the connecting wires can be prevented from contacting the fixed back plate 24, and the occurrence of cracks and the like on the display surface of the display screen 22 can be reduced.

Since in the case of a gap between the display screen 22 and the housing 5 at the position of the display window 5a, some impurities and water may enter into the liquid detector through the gap, which may affect the use of the liquid detector, the display module 2 further includes a sealing ring 21. The display screen 22 is arranged in the receiving cavity at the position of the display window 5a by means of the sealing ring 21. In this way, the sealing ring 21 seals the gap between the display screen 22 and the receiving cavity at the position of the display window 5a, so that impurities and water are prevented from entering the liquid detector through the gap.

The shape of the seal ring 21 may be designed according to the shapes of the display window 5a and the display screen 22, for example, if the shapes of the display window 5a and the display screen 22 are both rectangular, then the shape of the seal ring 21 is also rectangular. In some examples, the sealing ring 21 may be fixed in the receiving cavity at the position of the display screen 22 and the display window 5a by gluing. In other examples, a mounting groove 811 is provided in the receiving cavity at the position of the display window 5a, and the sealing ring 21 is mounted in the mounting groove 811 and connected with the display screen 22 by glue. The cross section of the sealing ring 21 is rectangular, so that the sealing ring 21 can be conveniently placed (for example, placed in the mounting groove 811, and for example, placed in the accommodating cavity at the position of the display window 5 a), and the sealing ring 21 is prevented from being twisted, knotted or wound.

In some embodiments, the liquid detector further comprises a controller and at least one of an indicator light, a buzzer, a vibrator, a data transmission interface, and a camera disposed on the housing 5 and coupled to the controller. In some examples, the liquid detector comprises one of the above, for example, may be an indicator light, a buzzer, a vibrator, a data transmission interface, or a camera. In some examples, the liquid detector includes at least two of the foregoing, such as an indicator light and a buzzer, and further such as an indicator light, a buzzer, and a vibrator, and is not limited to the foregoing combinations, for example, the liquid detector may include an indicator light, a buzzer, a vibrator, a data transmission interface, and a camera.

The above description is only for the specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto, and any person skilled in the art will appreciate that changes or substitutions within the technical scope of the present disclosure are included in the scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
