Description

Technical Field

[0001] This utility model relates to the field of alarm technology, and more specifically, to a water immersion alarm device. Background Technology

[0002] A water leak alarm is a device used to detect water leaks or immersion. It is commonly used in homes, offices, warehouses, and other locations to prevent property damage caused by water leaks. A water leak alarm typically consists of a sensor, an alarm unit, and a power supply. The sensor monitors changes in ambient moisture levels; once water comes into contact with the sensor, the alarm mechanism is triggered.

[0003] Moisture in the air may form a thin film of water or condense into water droplets on the sensor surface. Although this phenomenon does not mean that there is actual water immersion or leakage, water can easily accumulate on or under the contact surface of the water immersion alarm, which may cause the sensor to mistakenly think that there is continuous water immersion, thus triggering a false alarm. Utility Model Content

[0004] This invention provides a water immersion alarm device to solve the problem in the prior art where moisture in the air easily condenses on the sensor, causing the sensor to easily generate false alarms.

[0005] This utility model provides a water immersion alarm device, which includes: a housing having a cavity; a water immersion sensing module disposed on the housing, the water immersion sensing module having a monitoring end located outside the cavity; an alarm module disposed inside the cavity, the alarm module emitting an alarm when the monitoring end comes into contact with liquid; a heating module disposed inside the cavity, the heating module being used to heat the monitoring end to evaporate the moisture on the monitoring end; and a control module disposed inside the cavity, the water immersion sensing module, the alarm module, and the heating module being electrically connected to the control module.

[0006] Furthermore, the water immersion alarm device also includes a camera component, which is mounted on the housing and electrically connected to the control module. The camera component captures images of the environment outside the housing.

[0007] Furthermore, the water immersion sensing module includes: a first detection probe electrically connected to the control module, the first detection probe including two spaced-apart first metal heads, the first metal heads protruding from the top of the housing through the cavity; and a second detection probe electrically connected to the control module, the second detection probe including two spaced-apart second metal heads, the second metal heads protruding from the bottom of the housing through the cavity.

[0008] Furthermore, the control module includes: a power supply, disposed within the cavity; a circuit board, disposed within the cavity, electrically connected to the power supply; a water immersion sensing module, an alarm module, and a heating module, each electrically connected to the circuit board; a first metal head disposed on the top surface of the circuit board; and a second metal head disposed on the bottom surface of the circuit board.

[0009] Furthermore, the heating module includes a first resistive element, which is electrically connected to the circuit board and abuts against a first metal head. When current flows through the first resistive element on the circuit board, the first resistive element heats up to heat the first metal head; and / or, the heating module includes a second resistive element, which is electrically connected to the circuit board and abuts against a second metal head. When current flows through the second resistive element on the circuit board, the second resistive element heats up to heat the second metal head.

[0010] Furthermore, the water immersion alarm device also includes a water immersion sensor and a mounting cover. The mounting cover is located on the side of the housing near the second metal head and is spaced apart from the housing. The mounting cover is detachably connected to the housing and has mounting holes. The mounting cover hangs the water immersion alarm device on the external mounting surface through the mounting holes. The water immersion sensor is located on the side of the mounting cover facing the housing and is electrically connected to the control module. The water immersion sensor includes a third detection probe located outside the mounting cover. When the third detection probe comes into contact with liquid, the alarm module issues an alarm.

[0011] Furthermore, the water immersion sensor also includes: a connecting part, one end of which is located between the mounting cover and the housing, and the other end of which extends out of the mounting cover and is electrically connected to the third detection probe; two conductive parts, which are disposed at the ends of the connecting part located between the mounting cover and the housing, and are disposed on the side of the mounting cover facing the housing. The conductive parts are used to abut against the second metal head to conduct water immersion sensor and control module. The two conductive parts are disposed one-to-one with the two second metal heads.

[0012] Furthermore, the housing includes an upper shell and a lower shell, which fit together to form a cavity. An opening is provided on the side wall of the upper shell, and the opening is correspondingly set with the camera component. The camera component captures images of the external environment through the opening. A first metal head protrudes from the upper shell, and a second metal head protrudes from the lower shell. A support foot is provided at the bottom of the lower shell.

[0013] Furthermore, a sealing element is provided between the upper shell and the lower shell to seal the gap between them.

[0014] Furthermore, the alarm module includes a light alarm module and a sound alarm module, which are respectively installed in the cavity and electrically connected to the control module.

The light-transmitting part is correspondingly installed with the light alarm module, and the sound alarm module abuts against the housing.

[0015] By applying the technical solution of this utility model, the water immersion sensing module monitors water immersion by having its monitoring end come into contact with moisture. By incorporating a heating module within the water immersion alarm device, the monitoring end is heated, thus evaporating condensation, splashes, and other non-water immersion moisture, preventing false alarms caused by this moisture, thereby reducing the false alarm rate and improving alarm accuracy. This also reduces user inconvenience and enhances user trust in the alarm system, especially in high-humidity environments such as bathrooms and kitchens, allowing users to use the device with greater peace of mind without worrying about frequent malfunctions. Furthermore, it avoids performance degradation or damage caused by prolonged moisture on the monitoring end, enhancing the reliability of the water immersion sensing module, extending the lifespan of the water immersion alarm device, reducing maintenance requirements, and thus lowering user maintenance costs and inconvenience.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] like Figures 1 to 4As shown, Embodiment 1 of this utility model provides a water immersion alarm device, which includes a housing 10, a water immersion sensing module 20, an alarm module 30, and a control module 40. The housing 10 has a cavity. The water immersion sensing module 20 is disposed on the housing 10 and has a monitoring end located outside the cavity. The alarm module 30 is disposed inside the cavity; when the monitoring end comes into contact with liquid, the alarm module 30 sounds an alarm. A heating module is disposed inside the cavity and is used to heat the monitoring end to evaporate moisture on it. The control module 40 is disposed inside the cavity, and the water immersion sensing module 20, alarm module 30, and heating module are electrically connected to the control module 40. The control module 40 is signal-connected to the user's smart device, so that the control module 40 can receive information from the water immersion sensing module 20, alarm module 30, and heating module in real time and transmit the information to the user terminal. The user terminal can also control the operation of the above modules through the control module 40.

[0037] By applying the technical solution of this utility model, the water immersion sensing module 20 monitors water immersion by contacting moisture at its monitoring end. A heating module is installed within the water immersion alarm device to heat the monitoring end, thus evaporating condensation, splashes, and other non-water immersion moisture, preventing false alarms caused by this moisture, thereby reducing the false alarm rate and improving alarm accuracy. This also reduces user inconvenience and enhances user trust in the alarm system, especially in high-humidity environments such as bathrooms and kitchens, allowing users to use the device with greater peace of mind without worrying about frequent malfunctions. Furthermore, it avoids performance degradation or damage caused by prolonged moisture at the monitoring end, enhancing the reliability of the water immersion sensing module 20, extending the service life of the water immersion alarm device, reducing maintenance requirements, and thus lowering user maintenance costs and inconvenience.

[0038] like Figure 1 As shown, the housing 10 includes an upper shell 11 and a lower shell 12 that interlock with each other. The upper shell 11 and the lower shell 12 are fixedly connected by fasteners 13 and cooperate to form a cavity. A sealing element 80 is provided between the upper shell 11 and the lower shell 12 to seal the gap between them. This sealing element 80 effectively seals the interior of the water immersion alarm, preventing moisture and dust from entering, enhancing the sealing performance of the housing 10, improving the waterproof and dustproof rating of the water immersion alarm, protecting the internal electronic components from external environmental influences, thereby extending the service life of the device and ensuring stable operation of the alarm in various harsh environments.

[0039] Specifically, the sealing element 80 is a silicone ring, and sealing grooves are correspondingly provided on the edges of the end faces of the upper shell 11 and the lower shell 12. When the upper shell 11 and the lower shell 12 are fastened together, the sealing element 80 is located in the sealing groove and is interference-fitted with the sealing groove. At the same time, the sealing element 80 is fixed to the lower shell 12 by fasteners.

[0040] like Figures 1 to 3 As shown, the water immersion sensing module 20 includes a first detection probe and a second detection probe. The first detection probe is electrically connected to the control module 40 and includes two spaced-apart first metal heads 21 extending from the top of the housing 10 through the cavity. The second detection probe is also electrically connected to the control module 40 and includes two spaced-apart second metal heads 22 extending from the bottom of the housing 10 through the cavity. This configuration allows the water immersion sensing module to monitor water immersion from multiple angles and at different water levels. It can detect not only water accumulation at the bottom of the housing 10 but also potential water droplets falling from the top, enhancing the detection range and sensitivity of the water immersion alarm. When water comes into contact with either the first metal head 21 or the second metal head 22, a conductive path is formed between them, triggering the control module 40, which in turn activates the alarm module 30 to send an alarm signal. Meanwhile, the heating function of the heating module can quickly evaporate residual moisture, which not only avoids continuous false alarms caused by moisture, but also prevents the first metal head 21 and the second metal head 22 from rusting due to water immersion, thus extending the service life of the water immersion sensor module 20.

[0041] It is understandable that monitoring water immersion by forming a conductive circuit with the control module 40 when two metal detectors come into contact with water is an existing technology, and will not be elaborated on here.

[0042] like Figure 4 As shown, in one embodiment of this application, an application scenario for the water immersion alarm device is provided, namely, it is placed on the ground 02. A support foot 121 is provided at the bottom of the lower housing 12, and the housing 10 is placed on the ground 02 via the support foot 121. The first metal head 21 protrudes from the upper housing 11, and the second metal head 22 protrudes from the lower housing 12, with a gap between them and the ground. This not only prevents the second metal head 22 from abrading against the ground, but also prevents water from the ground from entering the housing 10 and damaging the internal components.

[0043] Specifically, three support feet 121 are arranged circumferentially at the bottom of the lower shell 12 to avoid the second metal head 22.

[0044] In other embodiments, the support foot 121 may be single or multiple, and the structure may be circular, square, or other shapes.

[0045] In this embodiment, the water immersion sensing module 20 includes one set of first probes and two sets of second probes. In other embodiments, the number of first and second probes is not limited and can be selected according to actual operating conditions.

[0046] In other embodiments, the water immersion alarm device can be placed at the bend of the water pipe 03 or below a leak point that is prone to leakage. It can detect the upper leak point and whether water accumulation at the bottom has occurred simultaneously by using the first detection probe at the top of the housing 10 and the second detection head at the bottom.

[0047] like Figure 1 As shown, the control module 40 includes a power supply 41 and a circuit board 42. The power supply 41 is housed within the cavity. The circuit board 42 is also housed within the cavity and is electrically connected to the power supply 41. The water immersion sensor module 20, the alarm module 30, and the heating module are all electrically connected to the circuit board 42. A first metal head 21 is located on the top surface of the circuit board 42, and a second metal head 22 is located on the bottom surface. Thus, when the water immersion sensor module 20 detects a water immersion signal, the circuit board 42 can respond quickly, causing the alarm module 30 to issue a warning. Simultaneously, based on customer instructions, the heating module is activated to accelerate water evaporation, effectively preventing false alarms and sensor corrosion. This integrated design not only optimizes the space utilization within the cavity but also enhances the reliability and lifespan of the water immersion alarm.

[0048] Specifically, circuit board 42 is a PCB board. A WIFI antenna 43 is also provided on circuit board 42 for receiving and transmitting signals. Circuit board 42 is snap-fitted between the upper shell 11 and the lower shell 12. The power supply 41 consists of two batteries. Two sets of connectors are provided on the bottom of both sides of circuit board 42. Each set of connectors includes two spaced elastic metal wires 44, which are electrically connected to the positive and negative terminals of the batteries, respectively. The side of the lower shell 12 facing the upper shell 11 has two mounting slots, and the two batteries are fixed in the two mounting slots respectively.

[0049] like Figure 1 As shown, the water immersion alarm device also includes a camera component 50, which is mounted on the housing 10 and electrically connected to the control module 40. The camera component 50 is used to capture images of the environment outside the housing 10. Thus, when the water immersion sensor module 20 detects water immersion and triggers the alarm, the control module 40 can control the camera component 50 to start immediately, capturing and recording the actual situation of the environment where the alarm is located. The image information is then transmitted to the user's smart device via a wireless network, allowing the user to remotely view the scene in real time and confirm whether water immersion has indeed occurred or if it is a false alarm. This provides a visual verification method and effectively avoids unnecessary interference or false alarms.

[0050] Specifically, an opening 110 is provided on the side wall of the upper shell 11. The opening 110 is correspondingly provided with the camera component 50. The camera component 50 captures images of the external environment through the opening 110. The camera component 50 has a camera located inside the cavity. The lens of the camera faces the opening 110 and captures images of the external environment through the opening 110.

[0051] There are no restrictions on the camera's angle; it is sufficient that the camera can capture images of the ground near the housing 10 through the opening 110.

[0052] Specifically, when the water immersion sensor module 20 detects moisture in the environment through its monitoring terminal, the alarm module 30 will sound an alarm and alert the user to the risk of water immersion. Subsequently, the camera component 50 will capture images of the environment surrounding the housing 10 and send them to the user's smart device. The user can then review the images to determine whether a genuine water immersion has occurred or if it is a false alarm. If it is a false alarm, the customer can remotely control the alarm module 30 to stop the alarm via the control module 40 through their smart device. The control module 40 will then activate the heating module to heat the monitoring terminal. The water immersion sensor module 20 will then stop monitoring. After the heating module has heated one end of the monitoring terminal for a preset time, most of the moisture that triggered the false alarm will evaporate, reducing the possibility of subsequent false alarms. The heating module will then stop working, and the water immersion sensor module 20 will resume monitoring. If it is not a false alarm but a genuine water immersion hazard has occurred, the customer can immediately become aware and take appropriate action. The alarm module 30 will not be shut down, and the heating module will not operate.

[0053] It is understandable that the electrical connections or signal transmission and control between different modules are existing technologies, and will not be elaborated on here.

[0054] Furthermore, the heating module includes a first resistor and a second resistor. The first resistor is electrically connected to the circuit board 42 and abuts against the first metal head 21. When heating of the first metal head 21 is required, the circuit board 42 controls the water immersion sensor module 20 to stop working, and then activates the circuit containing the first resistor, allowing current to flow through the first resistor on the circuit board 42, thereby heating the first resistor to heat the first metal head 21 and evaporate the moisture on it. The second resistor is electrically connected to the circuit board 42 and abuts against the second metal head 22. When heating of the second metal head 22 is required, the circuit board 42 controls the water immersion sensor module 20 to stop working, and then activates the circuit containing the second resistor, allowing current to flow through the second resistor on the circuit board 42, thereby heating the second resistor to heat the second metal head 22 and evaporate the moisture on it. The above-mentioned design utilizes the thermal effect of resistance to quickly evaporate water droplets adhering to the metal head, effectively preventing false alarms caused by environmental factors such as condensation and splashing water, and protecting the sensor's metal head from rust damage, ensuring the long-term stable operation of the water immersion alarm. By using heating and evaporation, not only is the ease of use of the alarm improved, but its adaptability and reliability in humid environments are also enhanced.

[0055] The number of first resistive elements corresponds one-to-one with the number of first metal heads 21, and the number of second resistive elements corresponds one-to-one with the number of second metal heads 22. The first and second resistive elements can be structures such as resistance wires or resistance blocks, and are mounted on the circuit board.

[0056] In this embodiment, the heating temperature of the heating module is between 45°C and 55°C. This temperature range is higher than the indoor temperature, which can evaporate the water droplets on the metal head without overheating and burning the circuit board 42 and other components, thus ensuring the normal operation of the water immersion alarm device.

[0057] In other embodiments, the heating temperature of the heating module can be adjusted according to actual operating conditions.

[0058] In some embodiments, the heating module may include only the first resistive element.

[0059] In other embodiments, the heating module may include only the second resistive element.

[0060] like Figures 5 to 8As shown, in Embodiment 2 of this application, a water immersion alarm device is provided, which is mounted on a wall or other mounting surface. The difference from Embodiment 1 is that the water immersion alarm device further includes a water immersion sensor 61 and a mounting cover 70. The mounting cover 70 is located on the side of the housing 10 near the second metal head 22 and is spaced apart from the housing 10. The end of the second metal head 22 extending out of the lower housing 12 is located inside the mounting cover 70; that is, in this embodiment, the second metal head 22 is not used to monitor whether water immersion has occurred. The mounting cover 70 is detachably connected to the housing 10, and the mounting cover 70 is provided with a mounting hole 701. The mounting cover 70 is used to hang the water immersion alarm device on the external mounting surface 01 through the mounting hole 701. A water immersion sensor 61 is disposed on the side of the mounting cover 70 facing the housing 10 and is electrically connected to the control module 40. The water immersion sensor 61 includes a third detection probe, which is located outside the mounting cover 70. When the mounting cover 70 is attached to the mounting surface, the water immersion sensor 61 is located below the mounting cover 70, i.e., below the first detection probe, and works in conjunction with the first detection probe to monitor water immersion at different heights and orientations. When the third detection probe comes into contact with liquid, the alarm module 30 issues an alarm. Thus, the third detection probe extends beyond the mounting cover 70 and is directly exposed to the potential water immersion environment. When the third detection probe comes into contact with liquid, its state change can be quickly transmitted to the control module 40, triggering the alarm module 30 to respond immediately and issue an alarm, realizing real-time monitoring and early warning of water immersion events.

[0061] Furthermore, the externally replaceable water immersion sensor 61 and mounting cover 70 allow the water immersion alarm device to switch between different installation modes according to different usage requirements or installation space. This reduces the maintenance complexity of the equipment while improving the flexibility and reliability of the device.

[0062] Among them, the external mounting surface 01 can be a wall, the side of the device, etc. In this application, the water immersion alarm device is mounted on the wall.

[0063] like Figure 5 and Figure 6As shown, the water immersion sensor 61 also includes a connecting portion 611 and two conductive portions 612. One end of the connecting portion 611 is located between the mounting cover 70 and the housing 10, while the other end extends out of the mounting cover 70 and is electrically connected to the third detection probe. The two conductive portions 612 are located at the end of the connecting portion 611 between the mounting cover 70 and the housing 10, and are positioned on the side of the mounting cover 70 facing the housing 10. The conductive portions 612 abut against the second metal heads 22 to conduct electricity between the water immersion sensor 61 and the control module 40. The two conductive portions 612 correspond one-to-one with the two second metal heads 22. Thus, when water overflows or comes into contact with the third detection probe, the circuit between the conductive portion 612 and the second metal heads 22 closes, thereby triggering signal transmission between the water immersion sensor 61 and the control module 40, achieving timely and accurate water immersion detection and alarm functions. Furthermore, the conductive part 612 is electrically connected to the circuit board 42 through the second probe, without needing to extend into the housing 10. Instead, it can be fixed on the conductive part 612, thus simplifying the overall structure of the water immersion alarm device. This allows the water immersion sensor 61 to be detachably connected to the housing 10 along with the mounting cover 70, making it very convenient to assemble and disassemble the water immersion alarm device according to actual installation and usage requirements.

[0064] In this embodiment, the connecting part 611 is a conductive cable with two conductive wires branching out at its end. Each conductive wire has a metal terminal 6111 at its end. The two metal terminals 6111 are electrically connected to two conductive parts 612, each of which is a metal sheet. The metal sheet and the metal terminals 6111 are fixed together on the mounting cover 70 using fasteners. The metal sheet has a spring clip groove, which corresponds to the second metal head 22. When the mounting cover 70 and the housing 10 are installed in place, the second metal head 22 is positioned within the spring clip groove, which holds the end of the second metal head 22 extending out of the housing 10, thus enabling current conduction.

[0065] Furthermore, the mounting cover 70 and the housing 10 are engaged by a snap-fit ​​structure. Three snap-fit ​​strips 122 are spaced circumferentially at the bottom of the lower housing 12. The snap-fit ​​strips 122 are located at the ends of the support feet 121. The mounting cover 70 has three snap-fit ​​grooves 71 on the side facing the lower housing 12. When the mounting cover 70 and the housing 10 are installed, the housing 10 and the mounting cover 70 can be fixed by rotating the snap-fit ​​strips 122 and the snap-fit ​​grooves 71 until they are snapped into place. When the housing 10 and the mounting cover 70 are installed in place, the end of the second metal head 22 is located in the spring clip groove. This makes disassembly convenient and does not require professional operation by the user, thus improving the practicality of the water immersion alarm device and the user experience.

[0066] The snap-fit ​​mechanism between the mounting cover 70 and the housing 10 is existing technology. The specific snap-fit ​​structure can be adjusted and replaced according to installation requirements, as long as it enables detachable assembly. To ensure proper snap-fit ​​installation, indicator marks can be placed on the housing 10 or the mounting cover 70 to indicate alignment. Ensuring the end of the second metal head 22 is precisely within the spring clip groove during proper snap-fit ​​installation can be achieved through software or multiple simulations during actual machining; this is also existing technology and will not be elaborated upon here.

[0067] Specifically, the third detection probe has two third metal heads 613. The water immersion sensor 61 also includes a housing 610, which is located outside the mounting cover 70. The connecting part 611 and the third metal heads 613 both extend from the housing 610. The housing 610 is also provided with fixing holes 614, which can be fastened to the external mounting surface or wall using fasteners, ensuring the stability of the water immersion alarm device installation and the detection accuracy of the third detection probe.

[0068] like Figure 1 As shown, the alarm module 30 includes a light alarm module 31 and a sound alarm module 32. The light alarm module 31 and the sound alarm module 32 are respectively disposed within the cavity and electrically connected to the control module 40. A light-transmitting section is provided on the housing 10, which is sealed to the housing 10. The light-transmitting section corresponds to the light alarm module 31, and the sound alarm module 32 abuts against the housing 10. This eliminates the need for through holes on the housing 10 corresponding to the light alarm module 31 and the sound alarm module 32 for light and sound transmission, improving the housing's sealing performance, reducing unnecessary openings, preventing moisture from entering the housing 10, improving the overall protection level of the device, and extending the service life of the water immersion alarm. Simultaneously, it achieves dual visual and auditory warnings, improving the effectiveness and immediacy of the alarm.

[0069] Specifically, the light alarm module 31 includes an indicator light, which is located on the top of the circuit board 42. The part of the upper shell 11 corresponding to the indicator light is thinned to allow light to pass through and ensure the propagation of the light.

[0070] The sound alarm module 32 includes a speaker, which is located on the top of the circuit board 42. The speaker can abut against the upper shell 11 and can resonate with the upper shell 11 to produce sound while emitting sound, ensuring the propagation of sound.

[0071] Specifically, the alarm module 30 also includes a button section, which includes button hardware 33, a user button 34, and a support member 35. The button hardware 33 is located on top of the circuit board 42 and is electrically connected to the circuit board 42. It can be used to control the shutdown of the light alarm module 31 and the sound alarm module 32. The support member 35 is fastened to the top of the button hardware 33 by fasteners, and the button hardware 33 passes through the support member 35. The user button 34 is fixedly located on the top of the support member 35, and the support member 35 supports the user button 34. The upper shell 11 is provided with a pressing hole 111 corresponding to the user button 34. The top of the user button 34 protrudes through the pressing hole 111 for easy pressing by the user. By pressing the user button 34, the user can press the button hardware 33. The user can press and hold the user button 34 to check whether the internal light alarm module 31 and the sound alarm module 32 are working properly or to shut down the alarm.

[0072] The specific pressing duration or working mode of the user button 34 can be selected according to usage needs. The user button 34 is made of rubber to increase the waterproof performance of the housing 10.

[0073] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0074] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0075] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0076] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0077] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0078] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
