Abstract
Description
Technical Field
[0001] This utility model relates to the field of keyboard technology, and more specifically, to a keyboard with a heating function. Background Technology
[0002] A keyboard is a device used to input commands and data for operating computer equipment. To improve typing feel and alleviate finger stiffness in winter, keyboards can be heated using external devices or special designs. Most existing heated keyboards achieve this by adding a heating element inside the keyboard. The heat generated by this element heats the keycaps, raising their temperature. However, since the keycaps and key switches are mostly made of plastic, they are prone to deformation during prolonged use, leading to frequent replacements and increasing the cost of using the keyboard.
[0003] Based on this, a keyboard with a heating function is proposed. Summary of the Invention

[0024] To make the objectives and advantages of this utility model clearer, the utility model will be further described below with reference to the embodiments; it should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0025] Please see Figures 1-6As shown, a keyboard with a heating function includes a bottom shell 1. A heating cavity 101 is fixedly installed at one corner of the upper surface of the bottom shell 1. A heater 102 is fixedly installed at the rear end of the outer surface of the heating cavity 101. Heating rods are fixedly provided on both sides of the front end of the outer surface of the heater 102. The heating rods extend through the heating cavity 101 and into it. A micro-flow pump 103 is fixedly installed at the front end of the heating cavity 101. A conduit is installed between the micro-flow pump 103 and the heating cavity 101. Several positioning frames 2 are evenly fixedly installed on the upper surface of the bottom shell 1.
[0026] It should be noted that by setting a heating liquid inside the heating chamber 101, the heating liquid inside the heating chamber 101 is heated by the heater 102 to raise its temperature. The heated liquid can then be discharged through the micro-pump 103 for use in heating the keyboard.
[0027] A contact 201 is fixedly installed on the inner bottom surface of the positioning frame 2, and a fixing frame 202 is fixedly installed on the upper surface of the positioning frame 2. A slot 203 is opened through the lower part of the front and rear ends of the outer surface of the fixing frame 202. A guide shaft 3 is movably inserted into the fixing frame 202. The lower surface of the guide shaft 3 contacts the upper surface of the contact 201. A locking block 301 is fixedly installed on the lower part of the front and rear ends of the guide shaft 3. A spring piece is connected between the locking block 301 and the outer surface of the guide shaft 3.
[0028] It should be noted that the keyboard input is achieved by pressing the contact 201 through the guide shaft 3. The angle of the locking block 301 is adjusted by the spring sheet through the slot 203 opened on the fixed frame 202. First, the locking block 301 is pressed to control its unfolding angle and retract. Then, when the guide shaft 3 is inserted into the fixed frame 202, the pressure on the locking block 301 contacts it, and the spring sheet controls the locking block 301 to reset and unfold, thus locking it into the slot 203, thereby completing the fixed connection between the guide shaft 3 and the fixed frame 202.
[0029] A series of guide shafts 3 are connected on their adjacent sides and a guide hose 5 is installed. One end of the guide hose 5 is connected to the micro guide pump 103, and the other end of the guide hose 5 is connected to the heating chamber 101. A top shell 6 is fixedly installed on the upper surface of the bottom shell 1.
[0030] It should be noted that the heating liquid diverted by the micro-diversion pump 103 is circulated through the diversion hose 5, and the diversion shaft 3 is used as the turning point of the heating liquid circulation, so that the heating liquid entering the diversion shaft 3 can stay in the diversion shaft 3 for a short time, thereby further controlling the extension of the heating liquid.
[0031] A fixing seat 4 is provided on one side of the outer surface of several positioning frames 2 that are close to each other. The fixing seat 4 is fixedly connected to the upper surface of the bottom shell 1. A clamp 401 is fixedly installed on the upper surface of the fixing seat 4. Locking screws 402 are spirally inserted through both ends of the clamp 401 and the upper surface of the fixing seat 4. The clamp 401 is sleeved on the outer surface of the flow guide hose 5.
[0032] It should be noted that the guide hose 5 is clamped and fixed by the fixing seat 4 and the clamp 401, so that the guide hose 5 is in a bent state, so as to reserve enough room for the guide shaft 3 to ensure the normal movement of the guide shaft 3 and prevent the use of the keyboard from being affected.
[0033] Several keycaps 601 are inserted and installed on the upper surface of the top shell 6 corresponding to the positioning frame 2. Each keycap 601 has an opening in the middle of its upper surface. A touch cavity 602 is fixedly installed on the keycap 601 through the inner surface of the opening. A shaft 603 is connected to the middle of the lower surface of the touch cavity 602. The shaft 603 is fixedly connected to the upper surface of the guide shaft 3.
[0034] It should be noted that the keycap 601 is used for normal keyboard input. By setting the contact cavity 602, the heating fluid staying in the guide shaft 3 can be introduced into it through the shaft body 603, thereby heating the contact cavity 602. Under this condition, the keycap 601 will come into contact with the contact cavity 602 by touching it. The heating effect of the contact cavity 602 is used to indirectly achieve the heating effect of the keycap 601, thereby improving the comfort of using the keycap 601.
[0035] Secondly, the contact cavity 602 and the keycap 601 are not connected to each other, thus creating a gap between the contact cavity 602 and the keycap 601 to reduce the heat transfer to the keycap 601 and avoid the deformation problem that the keycap 601 is prone to due to prolonged heating.
[0036] In use, the heater 102 is first activated to heat the heating liquid in the heating chamber 101 to raise its temperature. The heated liquid is then discharged through the micro-pump 103 and transmitted to each guide shaft 3 through the guide hose 5. The heated liquid entering the guide shaft 3 can then enter the touch cavity 602 through the shaft body 603, thereby raising the temperature of the touch cavity 602 and indirectly increasing the temperature of the keycap 601, thus achieving the effect of keyboard heating. At the same time, during the heating process, as the micro-pump 103 continues to run, the heating liquid can be circulated from the heating chamber 101 to the touch cavity 602 to ensure continuous heating and heat preservation of the touch cavity 602.
[0037] Secondly, when the heating fluid is transferred through the flow tube 5 and the touch cavity 602 is heated by the heating fluid, the heating fluid is enclosed inside, thus avoiding contact with the keyboard. This reduces the impact of heating on the keyboard while heating.
[0038] The above are merely embodiments of this utility model and are not intended to limit the scope of this 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 principle of this utility model should be included within the scope of the claims of this utility model.
