Description

Technical Field

[0001] This utility model relates to the field of touch panel technology, specifically to a touch module for a household vacuum freeze dryer. Background Technology

[0002] Freeze-drying is a method of preserving a substance by first freezing it into a solid state, and then sublimating the water content from the solid state into a gaseous state. In compressed air drying, freeze-drying works by lowering the temperature of the compressed air, causing the moisture in the compressed air to separate out. The working principle of a freeze dryer is similar to that of a refrigerator; compressed air passes through refrigerated compressed air pipes, and its temperature drops to the required level, achieving the desired dryness.

[0003] Existing household vacuum freeze dryers are controlled by industrial-grade integrated touchscreen computers, which have the following disadvantages: 1. High operational complexity, with nested multi-level menus and redundant functions, requiring frequent clicks to switch interfaces, resulting in high user learning costs and potential response delays; 2. High production costs, with high-cost industrial-grade screens and motherboards, requiring customized software development; 3. Difficult power consumption and maintenance, as high-power screens and systems require continuous power supply, and software failures require professional maintenance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a touch control module for a household vacuum freeze dryer, which is easy to operate and convenient to disassemble and maintain.

[0006] In this technical solution, a touch panel is provided on the touch panel box. The touch panel has a touch area that can be compressed when pressed, so as to ensure that the sensing circuit board receives the sensing signal and realize simple and effective control. This method of control is simple and reduces the difficulty of operation. Since the entire touch panel is a single module, the power consumption is low, and when it has a problem, it can be quickly replaced by simply unplugging the quick-connect terminal.

[0007] Preferably, the surface of the touch panel box on which the touch panel is mounted has through holes arranged opposite to each touch area, the touch-sensitive spring passes through the through holes and abuts against the touch area, and an LED light module connected to the sensing circuit board is provided in the through holes.

[0008] Preferably, the upper end of the touch panel box is provided with a positioning groove for installing the touch panel, the touch panel is installed in the positioning groove, and the through holes are arranged at intervals on the bottom wall of the positioning groove.

[0009] Preferably, the lower end of the touch panel box is provided with a base plate, and the base plate is detachably connected to the lower end of the touch panel box.

[0010] Preferably, the touch area is provided with control marks formed by screen printing.

[0011] The beneficial effects of this utility model are: the touch panel in this utility model adopts a single-layer logic design to eliminate redundant operations and reduce the difficulty of user operation; compared with the existing touch panel, the display screen and operating system are eliminated, and low-cost touch chips and customized PCBs are used to reduce costs; at the same time, the modular design of the touch panel is conducive to reducing power consumption and supporting quick replacement.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] like Figure 1 and Figure 2As shown in the figure, a specific embodiment of this utility model provides a touch control module 200 for a household vacuum freeze dryer. The panel structure can improve the convenience of operation, disassembly, and maintenance. Specifically, it includes a touch control panel box 100, with a touch control panel 200 at the top of the touch control panel box 100. The touch control panel 200 has touch areas arranged at intervals. A sensing circuit board 300 is provided inside the touch control panel box 100. The sensing circuit board 300 has a plurality of sensing touch springs 400 arranged at intervals. The upper end of each sensing touch spring 400 abuts against a corresponding touch area of ​​the touch control panel 200. The sensing circuit board 300 is also connected to a connection terminal 500 through a circuit.

[0019] like Figure 1 and Figure 2 As shown, in this embodiment, the touch panel 200 is installed on the upper end of the touch panel box 100. When used with the device, it is connected to the device through the connection terminal 500. By pressing the touch panel 200, the touch spring 400 senses the touch signal. In use, the user lightly touches the touch area according to the function of each touch area, which compresses the touch spring 400 to ensure that the sensing circuit board 300 receives the sensing signal, thus achieving simple and effective control. This method of control is simple and reduces the difficulty of operation. Since the entire touch panel 200 is a single module, the power consumption is low, and when it has a problem, it can be quickly replaced by simply unplugging the quick-connect terminal.

[0020] like Figure 1 and Figure 2 As shown, in order to assemble the touch-sensitive spring 400 inside the touch panel box 100, this embodiment provides through holes 110 on the surface of the touch panel 200 mounted in the touch panel box 100, which are arranged opposite to each touch area. The touch-sensitive spring 400 passes through the through holes 110 and abuts against the touch area. An LED light module connected to the sensing circuit board 300 is provided inside the through holes 110. At the same time, control marks are formed on the touch area by screen printing. In practical applications, the control marks can be hollowed-out patterns and text. When the user lightly touches the touch area, the corresponding LED light module will light up. The light passing through the hollowed-out patterns and text is more easily captured by the human eye, making it easier for the user to quickly identify, simplifying the control method, reducing the difficulty of operation, and making it more convenient for the user to operate.

[0021] like Figure 1 and Figure 2As shown, in this embodiment, a positioning groove 120 for mounting the touch panel 200 is provided at the upper end of the touch panel box 100. The touch panel 200 is installed in the positioning groove 120, and various through holes 110 are arranged at intervals on the bottom wall of the positioning groove 120. In this way, the touch panel 200 can be assembled in the positioning groove 120, improving the integrity of the overall structure. A base plate 130 is provided at the lower end of the touch panel box 100. The base plate 130 is detachably connected to the lower end of the touch panel box 100. In practical applications, the base plate 130 is fixed to the touch panel box 100 with screws to achieve the effect of protecting the circuit board and to facilitate disassembly.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
