Description

TECHNICAL FIELD

[0001] The utility model relates to a clothes airing machine, especially to a high-precision hanging weight detection system of clothes airing machine, which can detect and display the weight of clothes on the airing rod to avoid overloading of the airing rod. BACKGROUND

[0002] During the daily use of the clothes airing machine, users often face the problem of overloading of the airing rod, which not only may cause damage to the mechanical structure of the clothes airing machine, but also may cause deformation of the airing rod, failure of the lifting function and other safety hazards. In order to avoid these problems and improve the service life and safety of the clothes airing machine, many modern clothes airing machines are equipped with a hanging weight detection system.

[0003] The utility model patent with the authorized announcement number of CN206418314U discloses an overload protection device of an electric clothes airing machine, which detects the hanging weight of the electric clothes airing machine by using a hanging weight signal acquisition module to determine the state of the hanging weight of the clothes airing machine, and makes the electronic switch open or prohibits its closure when the hanging weight reaches the overload state, so as to stop the machine or prohibit the operation.

[0004] The utility model patent with the authorized announcement number of CN206873140U discloses an overload protection mechanism of an electric clothes airing machine, which includes a power module base, a steel wire rope turning pulley seat and a return spring.

One end of the return spring is arranged on the turning pulley seat, and the other end is arranged on the power module base. The overload protection mechanism further includes a pressure sensor, a pressure sensor base and a main control board. The pressure sensor is arranged on the pressure sensor base, and the pressure sensor base is arranged on the power module base. When the steel wire rope of the electric clothes airing machine is hung, the turning pulley seat is driven to slide along the sliding groove of the power module base to the pressure sensor and is pressed tightly. The pressure sensor outputs the sensed pressure electric signal to the main control board, and the main control board controls whether the motor stops according to the input pressure electric signal. The overload protection mechanism further includes a display screen. The main control board outputs the display signal to the display screen according to the input pressure electric signal to dynamically display the hanging weight.

In addition, due to the lack of effective mechanical protection measures, the sensor is easily damaged when subjected to an overload force, which affects the service life and reliability of the clothes airing machine.

[0058] like Figures 1 to 7 As shown, a high-precision weight detection system 100 for a clothes drying rack includes a rod base 10, a tension sensor 20, a steel wire rope 30, a control circuit 40, and a display screen 50 as its core components. The control circuit 40 is electrically connected to the display screen 50, receiving and processing weighing signals and displaying the weight information of the clothes on the display screen 50 in real time, providing the user with an intuitive weight reading. The tension sensor 20 is electrically connected to the control circuit 40 and, as a key component of the system, is responsible for accurately detecting the weight of the clothes on the drying rod and converting the weight signal into an electrical signal, which is then transmitted to the control circuit 40.

[0059] In terms of mechanical structure, the lower end of the wire rope 30 is firmly connected to the upper connection end of the tension sensor 20 through the upper fastener, and the connection direction is vertically downward to ensure stable and reliable force transmission; the lower connection end of the tension sensor 20 is vertically fixedly connected to the rod seat 10 through the lower fastener, which further enhances the overall stability of the system.

[0060] In particular, the upper connecting end, the lower connecting end of the tension sensor 20 and the steel wire rope 30 are strictly on the same vertical line, and this unique design can effectively avoid the interference of lateral force caused by the shaking of the clothes drying machine or wind blowing during operation, thereby ensuring the high precision and high stability of the weighing result. Even when the clothes weighing as light as 1 jin or as heavy as 50 jin are hung on the drying rod, the error can be accurately controlled within 1% of the weight of the clothes itself, and the weighing precision of the electronic scale level is truly achieved. The specific technical solutions will be described below:

[0061] The tension sensor 20 is the core component of the high-precision hanging weight detection system of the clothes drying machine, which has a delicate structure and can realize high-precision weight detection and reliable mechanical protection. The sensor mainly consists of an elastic body 21 and a sensing part 22. The elastic body 21 is the main structure of the sensor and has good elastic properties, which can vertically deform under external force. The elastic body 21 is provided with an upper connecting end b1 and a lower connecting end b2 at both ends, which are used for connecting with external structures (such as steel wire ropes and rod seats).

[0062] The sensing part 22 is located at the middle position of the elastic body 21, which makes the tension sensor 20 uniformly perceive the change of the weight of the clothes on the drying rod, thereby realizing high-precision weighing function. The sensing part 22 is provided with a deformation part d on the outside. The deformation part d is one of the key structures of the sensor, which will deform correspondingly when the elastic body 21 vertically deforms under external force. This deformation will trigger the resistance strain gauge or other sensitive elements inside the sensing part 22, thereby generating an electric signal proportional to the size of the external force. Through the processing and analysis of these signals by the control circuit, the accurate measurement of the weight of the clothes is finally realized.

[0063] In order to ensure the safety and reliability of the tension sensor 20 during use, a unique vertical limiting structure F is designed inside the elastic body 21. The structure is composed of limiting components that can move up and down, and its main function is to limit the maximum deformation stroke of the elastic body 21. When the weight of the clothes hung on the drying rod exceeds the designed range, the vertical limiting structure F will start to work, preventing the elastic body 21 from over-deforming, thereby avoiding the damage of the tension sensor 20 caused by excessive external force. This design not only prolongs the service life of the sensor, but also improves the stability and reliability of the whole system.

[0064] In addition, the fastening direction of the upper and lower fasteners of the tension sensor 20 is consistent with the up-and-down cooperation path direction of the vertical limiting structure F. This makes the sensor maintain the stability and consistency of the structure during installation and use, ensures that the force transmission direction is always vertical, thereby avoiding measurement errors caused by lateral force or non-vertical force interference. This integrated design concept not only optimizes the mechanical properties of the sensor, but also improves its adaptability in complex environments.

[0065] In addition, it needs to be pointed out that in the process of using the traditional clothes drying machine, the drying rod will produce lateral force due to wind blowing or shaking, which will have a significant impact on the weighing accuracy. However, the utility model ensures that the force transmission is completely vertical by vertically connecting the lower end of the steel wire rope 30 with the upper connecting end of the specific tension sensor 20 and vertically fixing the lower connecting end of the tension sensor 20 on the rod seat 10. The design of this vertical path enables the sensor to focus on detecting vertical force, thereby realizing high-precision weighing while avoiding measurement errors caused by lateral force, providing a solid technical foundation for high-precision hanging weight detection of the clothes drying machine.

[0066] As shown in Figure 5 and Figure 6 , the sensing part 22 includes an upper sensing part c1 and a lower sensing part c2, the upper side of the upper sensing part c1 is provided with an upper deformation part d1, and the lower side of the lower sensing part c2 is provided with a lower deformation part d2. In actual use, the weight of clothes on the drying rod will be transmitted to the elastic body 21 of the tension sensor 20 through the steel wire rope 30. The elastic body 21 deforms vertically under external force, and this deformation will be further transmitted to the upper deformation part d1 and the lower deformation part d2 of the sensing part 22. Since the upper sensing part c1 and the lower sensing part c2 are located on the upper and lower sides of the elastic body 21 respectively, they can sense the deformation at different positions.

[0067] When subjected to a small vertical force, for example, when only a small amount of light clothes is hung on the drying rod, the deformation of the elastic body 21 is relatively small. At this time, the deformation of the upper deformation part d1 and the lower deformation part d2 is also relatively slight, but it is enough to be detected by the sensing part 22 and generate a corresponding electrical signal. This enables the sensor to maintain high sensitivity even under low load conditions, ensuring accurate response to the weight change of light clothes.

[0068] With the increase of vertical force, for example, the weight of clothes hung on the drying rod gradually increases, and the deformation of the elastic body 21 will also increase accordingly. At this time, the upper deformation part d1 and the lower deformation part d2 will deform to different degrees. Since the upper sensing part c1 and the lower sensing part c2 are located at different positions of the elastic body 21, they can sense deformation in different directions and degrees. The design of this vertical up-down layout enables the sensor to capture deformation information more comprehensively, thereby realizing high-precision weighing.

[0069] The synergy of the upper deformation part d1 and the lower deformation part d2 is the key to achieving high-precision weighing. When the weight of the clothes on the drying rod changes, the deformation of the elastic body 21 will be transmitted to the upper deformation part d1 and the lower deformation part d2 simultaneously. These two deformation parts convert the deformation into electrical signals through internal resistance strain gauges or other sensitive elements. Since the upper sensing part c1 and the lower sensing part c2 are located on the upper and lower sides of the elastic body 21 respectively, they can sense the deformation at different positions, thereby providing more comprehensive and accurate deformation information.

[0070] By processing and analyzing these electrical signals through the control circuit 40, the system can accurately calculate the weight of the clothes on the drying rod. This dual-sensing part design enables the sensor to maintain high precision and stability under different load conditions. Even in extreme cases, such as hanging clothes weighing as light as 1 jin or as heavy as 50 jin, the error of the sensor can be strictly controlled within 1% of the weight of the clothes, achieving the precision of an electronic scale.

[0071] The vertical limiting structure F is a key technical means in the tension sensor 20, and its core purpose is to protect the elastic body 21 from excessive deformation under extreme load conditions, thereby ensuring the long-term stability and reliability of the sensor. Through precise mechanical settings, this structure limits the maximum deformation stroke of the elastic body 21 when subjected to vertical force, preventing the sensor from being damaged due to excessive external force.

[0072] Specifically, the vertical limiting structure F includes two oppositely arranged deformation reverse structures: a first deformation reverse structure r1 and a second deformation reverse structure r2. These two structures are located on the first side upper part and the second side lower part of the elastic body 21 respectively, forming a symmetrical limiting mechanism.

[0073] The vertical limiting structure F realizes precise control of the maximum deformation stroke of the elastic body 21 through the upper and lower limiting of the first limiting block r11 and the first limiting step r12, as well as the upper and lower limiting of the second limiting block r21 and the second limiting step r22. This double limiting mechanism not only improves the reliability of the sensor, but also ensures the stability of the sensor under various load conditions. When the weight of the clothes on the drying rod exceeds the design range, the vertical limiting structure F can quickly start to limit the deformation of the elastic body 21, thereby protecting the sensor from overload damage.

[0074] The design of the vertical limiting structure F not only considers the function of mechanical protection, but also focuses on the synergy with the overall structure of the sensor. The limiting block and the limiting step have very high matching precision, ensuring that they do not affect the sensitivity and accuracy of the sensor in normal working state.

[0075] In addition to the steel wire rope 30 and the tension sensor 20 fastening method needs to be highlighted, the center of the upper connecting end b1 of the tension sensor 20 is provided with a vertical upper threaded hole 01, used for connecting with the lower end of the steel wire rope 30. The lower end of the steel wire rope 30 is provided with an adjusting screw e, which is precisely screwed into the upper threaded hole 01. This threaded connection not only provides high-strength mechanical connection, but also allows fine-tuning of the tension of the steel wire rope 30 by rotating the adjusting screw e, thereby ensuring the stability of the system under different load conditions.

[0076] In order to further enhance the reliability of the connection, an adjusting screw e is screwed on the adjusting screw e. The locking nut e1 is pressed on the top surface of the upper connecting end of the tension sensor 20, and by applying additional pre-tightening force, it prevents the adjusting screw e from loosening due to vibration or external force during use. This double fastening mechanism not only improves the safety of the system, but also ensures that the connection between the steel wire rope 30 and the tension sensor 20 remains stable in long-term use.

[0077] The center of the lower connecting end b2 of the tension sensor 20 is provided with a vertical lower threaded hole 02, used for fixed connection with the rod base 10. The rod base 10 is made of aluminum alloy material, and has a U-shaped structure. This design not only reduces the weight of the system, but also provides good mechanical strength and corrosion resistance. Inside the rod base 10 is a fixed plate 11 for mounting and fixing the tension sensor 20.

[0078] The fixed bolt g connected to the rod base 10 is precisely screwed into the lower threaded hole 02, firmly fixing the tension sensor 20 on the rod base 10. This bolt connection not only provides high-strength mechanical fixation, but also allows precise adjustment of the position of the tension sensor 20 during installation, ensuring its vertical alignment with the steel wire rope 30. This vertical alignment is one of the key factors for achieving high-precision weighing, as it eliminates the interference of lateral forces, ensuring that the sensor only senses vertical forces.

[0079] By setting threaded holes on the upper and lower connecting ends b1 and b2 respectively, and using adjusting screw e and fixed bolt g for connection, the system not only realizes efficient force transmission, but also provides reliable mechanical fixation and adjustment functions. Specifically, the connection points of the steel wire rope 30 and the tension sensor 20 are precisely aligned on the same vertical line, and the system can efficiently transmit vertical forces, avoiding measurement errors caused by inconsistent force directions. This design ensures that the sensor maintains high-precision weighing performance under different load conditions.

[0080] In addition, the double fastening mechanism of the adjusting screw e and the locking nut e1, and the high-strength connection of the fixed bolt g, ensure that the connection between the steel wire rope 30 and the tension sensor 20 remains stable in long-term use.

[0081] In summary, the fastening mode of the steel wire rope 30 and the tension sensor 20 is an important technical means in the high-precision hanging weight detection system of the clothes drying machine. By setting threaded holes at the upper and lower connecting ends b1 and b2 respectively, and using adjusting screws e, locking nuts e1 and fixing bolts g for connection, the system not only realizes efficient force transmission and reliable mechanical fixation, but also provides adjustment function and installation convenience. The optimization of this fastening mode significantly improves the precision, stability and service life of the system, providing a solid technical guarantee for high-precision hanging weight detection of the clothes drying machine.

[0082] The tension sensor 20 adopts an S-shaped structure design and works based on the resistance strain principle, capable of accurately measuring tension and pressure. It has high measurement precision, strong stability, small temperature drift, good output symmetry, compact structure, excellent waterproof performance and other characteristics, and can measure both tension and pressure values, making it very suitable for high-precision hanging weight detection of the clothes drying machine. There are mature products on the market, such as the ZNLBS coin-type micro tension sensor of Zhenno Force, which can be an ideal choice for the system.

[0083] A high-precision hanging weight detection system for a clothes drying machine is introduced, and specific examples are applied to explain the principles and implementation methods of the present application. The above examples are only used to help understand the present application and core ideas. It should be noted that for ordinary technical personnel in this technical field, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
