[0001] This utility model belongs to the technical field of drying and preservation devices, and more specifically, it relates to an easy-to-apply preservation bag. Background Technology

[0002] Humidity control is a crucial aspect in daily life and in many industrial production, warehousing and logistics fields. Humid environments can easily cause a series of problems. In industrial production, electronic components and precision instruments are extremely sensitive to humidity. Excessive humidity can lead to short circuits and corrosion of electronic components, as well as reduced instrument accuracy and shortened lifespan.

[0003] However, existing food storage bags still have some shortcomings in use:

[0004] Firstly, currently, food preservation bags are simply placed inside cabinets where humidity needs to be controlled. When the cabinet is large, the food preservation bags cannot be evenly distributed inside the cabinet.

[0005] Secondly, food preservation bags become ineffective after absorbing enough moisture and need to be replaced regularly. However, workers cannot determine when the food preservation bags will expire, so they cannot replace expired food preservation bags in a timely manner. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides an easy-to-apply food preservation bag, which solves the problems that existing food preservation bags cannot be evenly distributed inside the cabinet, and that the food preservation bags become ineffective after absorbing enough moisture and need to be replaced regularly. However, workers cannot determine the expiration time of the food preservation bags, so they cannot replace the ineffective food preservation bags in a timely manner.

[0007] The purpose and effect of this utility model of an easy-to-stick food preservation bag are achieved by the following specific technical means: an easy-to-stick food preservation bag, including a back panel;

[0008] The back panel is a rectangular plate structure. Three Velcro straps are fixedly installed on the rear end face of the back panel, and a placement plate is fixedly installed on the front end face of the back panel. A through-hole is opened on the surface of the placement plate.

[0009] A fixed cylinder is installed on the upper end face of the placement plate. A pad is fixedly installed on the inner end face of the fixed cylinder, and an alarm mechanism is fixedly installed on the outer end face of the fixed cylinder.

[0010] A connecting rod, the upper part of which is located inside the fixed cylinder, the connecting rod is slidably engaged in the round hole on the surface of the placement plate, and a crossbar is fixedly installed on the lower end face of the connecting rod;

[0011] A fixed frame is fixedly installed on the upper surface of the pad, and two conductive circular plates are symmetrically installed inside the fixed frame;

[0012] The food preservation bag has two fixing rings fixedly installed on its upper end face, and the food preservation bag is located directly below the placement plate.

[0013] Furthermore, the alarm mechanism includes:

[0014] The power supply assembly has two sets of inclined support legs fixedly installed on its inner end face. The ends of the support legs are fixedly installed on the outer end face of the fixed cylinder. The power supply assembly is connected to the conductive circular plate at the rear end of the fixed frame through wires.

[0015] Furthermore, the alarm mechanism also includes:

[0016] The alarm is fixedly installed on the outer end face of the fixed cylinder. The alarm is connected to the power supply unit by a wire, and the other end of the alarm is connected to the conductive circular plate at the front end of the fixed frame by a wire.

[0017] Furthermore, a lifting plate is fixedly installed on the upper end face of the connecting rod, the outer end face of the lifting plate is in contact with the inner end face of the fixed cylinder, and a conductive plug is fixedly installed on the lower end face of the lifting plate, with the conductive plug located directly above the fixed frame.

[0018] Furthermore, a compression spring is sleeved on the outside of the connecting rod, with the upper end face of the compression spring fixedly connected to the lifting plate and the lower end face of the compression spring fixedly connected to the upper end face of the placement plate.

[0019] Furthermore, two hooks are fixedly installed on the lower end face of the crossbar, and the fixing ring at the upper end of the food storage bag is sleeved on the hook surface.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Easy installation: The main body of the back panel is a rectangular plate structure with three Velcro straps fixed to its rear end. This design allows the food storage bag to be easily attached to the surface of various items that need to be kept fresh, such as the inner wall of a wardrobe, the outer shell of an appliance, and storage boxes, without the need for additional fixing tools. The installation process is quick and convenient, greatly improving the ease of use. The two hooks on the lower end of the crossbar are connected to the fixing ring at the upper end of the food storage bag. When replacing the food storage bag, there is no need to remove the back panel, extending the service life of the Velcro straps.

[0022] 2. It can monitor in real time and issue an alarm when the food preservation bag fails. The fixed cylinder is equipped with an alarm mechanism. When the food preservation bag inside the bag gradually absorbs moisture and reaches a certain level, the weight increases, which will pull the connecting rod down. The conductive plug at the upper end of the connecting rod will then enter the fixed frame, making the two conductive discs conductive and triggering the alarm to remind the user in real time that the food preservation bag is close to failure and needs to be replaced in time to ensure that the items are always kept in a good preservation environment.

[0023] 3. The structure is compact, and the layout of each component of the food storage bag is reasonable. For example, the fixing tube not only supports the connecting rod and carries the alarm mechanism, but also works with the placement plate to fix the food storage bag. All parts work closely together to achieve multiple functions without taking up too much space. The bag is small and exquisite, making it easy to carry and store. Attached Figure Description

[0032] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0033] Example 1:

[0034] As attached Figure 1 To be continued Figure 6 As shown:

[0035] This utility model provides an easy-to-apply food storage bag, including a back panel 1;

[0036] The back panel 1 is a rectangular plate structure. Three Velcro straps 101 are fixedly installed on the rear end face of the back panel 1, and a placement plate 102 is fixedly installed on the front end face of the back panel 1. A through-hole is opened on the surface of the placement plate 102.

[0037] Fixed cylinder 2 is installed on the upper end face of the placement plate 102. A pad 5 is fixedly installed on the inner end face of the fixed cylinder 2, and an alarm mechanism is fixedly installed on the outer end face of the fixed cylinder 2.

[0038] The upper part of the connecting rod 3 is located inside the fixed cylinder 2. The connecting rod 3 is slidably locked in the round hole on the surface of the placement plate 102. A crossbar 301 is fixedly installed on the lower end face of the connecting rod 3.

[0039] The fixing frame 6 is fixedly installed on the upper end face of the pad 5, and two conductive circular plates 601 are symmetrically installed inside the fixing frame 6;

[0040] The food storage bag 9 has two fixing rings 901 fixedly installed on its upper end face, and the food storage bag 9 is located directly below the placement plate 102.

[0041] The alarm mechanism includes: a power supply assembly 7, with two sets of inclined support legs 701 fixedly installed on the inner end face of the power supply assembly 7, and the ends of the support legs 701 fixedly installed on the outer end face of the fixed cylinder 2. The power supply assembly 7 is connected to the conductive circular plate 601 at the rear end of the fixed frame 6 via wires; and an alarm 8, which is fixedly installed on the outer end face of the fixed cylinder 2. The alarm 8 is connected to the power supply assembly 7 via wires, and the other end of the alarm 8 is connected to the conductive circular plate 601 at the front end of the fixed frame 6 via wires. The alarm 8 will sound when powered on, thereby reminding people to replace the fresh food bag 9.

[0042] The upper end face of the connecting rod 3 is fixedly installed with a lifting plate 302. The outer end face of the lifting plate 302 is in contact with the inner end face of the fixed cylinder 2. The lower end face of the lifting plate 302 is fixedly installed with a conductive plug 3021. The conductive plug 3021 is located directly above the fixed frame 6. During use, the weight of the food storage bag 9 increases after absorbing a large amount of water, which overcomes the elastic force of the compression spring 4 and drives the connecting rod 3 to slide downward, thereby allowing the conductive plug 3021 to be inserted into the fixed frame 6. The conductive plug 3021 contacts the two conductive round plates 601, connecting the circuit. The alarm 8 sounds an alarm to remind people to replace the food storage bag 9.

[0043] The connecting rod 3 is fitted with a compression spring 4. The upper end of the compression spring 4 is fixedly connected to the lifting plate 302, and the lower end of the compression spring 4 is fixedly connected to the upper end of the placement plate 102. During use, when the preservation bag inside the preservation bag 9 is not ineffective, its weight is relatively light. Under the elastic force of the compression spring 4, the lifting plate 302 at the top of the connecting rod 3 is in a higher position. The conductive plug 3021 on the lower end of the lifting plate 302 is separated from the conductive round plate 601 inside the fixed frame 6, and the circuit is in an open circuit state.

[0044] Two hooks 3011 are fixedly installed on the lower end of the crossbar 301. The fixing ring 901 at the upper end of the food storage bag 9 is sleeved on the surface of the hooks 3011. During use, when the food storage bag 9 is replaced, it is not necessary to remove the back plate 1, which avoids the process of repeatedly removing and installing the Velcro 101 and can extend the service life of the Velcro 101.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In this invention, the back plate 1 serves as the main support for the entire device. Three Velcro straps 101 are fixedly installed on the rear end of the back plate 1, allowing the food storage bag to be easily attached to the desired position. A through-hole on the placement plate 102 provides a track for the vertical movement of the connecting rod 3. The food storage bag 9 is securely suspended by two fixing rings 901 on the upper end of the crossbar 301, hooked onto the lower end of the crossbar 301. The food storage bag 9 is located directly below the placement plate 102, effectively absorbing moisture. When the food storage bag 9 is not expired, its weight is relatively light. Under the elastic force of the compression spring 4, the lifting plate 302 at the top of the connecting rod 3 is in a higher position. The conductive plug 3021 on the lower end of the lifting plate 302 separates from the conductive circular plate 601 inside the fixing frame 6, resulting in an open circuit. The alarm 8 does not function. With prolonged use... As the food storage bag 9 absorbs a large amount of water, its weight increases, overcoming the elasticity of the compression spring 4 and causing the connecting rod 3 to slide downwards. This allows the conductive plug 3021 to be inserted into the fixing frame 6. The conductive plug 3021 contacts the two conductive discs 601, connecting the circuit. Since the power supply component 7 is connected to the conductive disc 601 at the rear end of the fixing frame 6 via wires, and the alarm 8 is connected to the power supply component 7 and the conductive disc 601 at the front end of the fixing frame 6, the alarm 8 starts working after the circuit is connected, sounding an alarm to remind the user that the food storage bag is close to saturation and needs to be replaced. This ensures that the environment is always in a low humidity state, effectively protecting the items from moisture damage. When replacing the food storage bag 9, it is not necessary to remove the back panel 1, thus avoiding the process of repeatedly removing and installing the Velcro 101, which can extend the service life of the Velcro 101.

[0047] Example 2: Based on the back plate 1 in Example 1, three Velcro straps 101 are fixedly installed on the rear end face of the back plate 1. In actual operation, the worker can increase the number of Velcro straps 101 according to the width of the back plate 1, for example, increase the number of Velcro straps 101 to five, which improves the stability of the back plate 1.
