Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, specifically a water dispenser with an easy-to-replace filter cartridge. Background Technology

[0002] As we all know, a water dispenser is a device that provides users with drinking water at a suitable temperature through electric heating or cooling, and is widely used in homes, offices, schools, and other places. It typically has functions such as water filtration, heating, and cooling, allowing people to conveniently obtain clean water at the right temperature. To facilitate filter replacement, existing water dispensers have an access door; simply open the access door to replace the filter. Furthermore, for ease of use, existing water dispensers can be directly connected to a water pipe, eliminating the need for an additional water bottle.

[0003] Existing water dispensers typically expose their outlets to the external environment when not in use, which presents a significant drawback: external dust, hair, and other impurities can easily accumulate at the outlet, potentially clogging the water flow over time; airborne dust and bacteria can also penetrate the machine through the outlet, adhering to the surfaces of components such as the heating element and filter, affecting not only water quality but also potentially causing water blockages and reduced heating efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the shortcomings of the existing technology, this utility model provides a water dispenser with easy filter replacement.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a water dispenser with an easy-to-replace filter element, comprising a body, an inspection door, a protective shell, a connecting mechanism, and a limiting mechanism. The inspection door is located at the rear of the body. The body has a liquid outlet. The protective shell is connected to the body via the connecting mechanism. A sliding groove is formed on the side of the body. One end of a slider extends into the sliding groove, and the other end of the slider is connected to one end of a telescopic rod. The other end of the telescopic rod is connected to one end of a connecting block, and the other end of the connecting block is connected to the protective shell. The protective shell is in contact with the machine body at its top. The liquid outlet is located inside the protective shell. One end of the long block is connected to the machine body, and the other end of the long block extends into the groove opened in the connecting block. One end of the spring is connected to the inner wall of the slide groove, and the other end of the spring is connected to the slider. There are two connecting mechanisms. The limiting mechanism includes a locking block and a locking groove. One end of the locking block is connected to the front of the machine body, and the locking block matches the locking groove. A controller is provided on the top of the machine body, and the controller is electrically connected to the machine body.

[0006] To improve the support effect, the present invention is improved by providing a support block at the bottom of the machine body, the support block being fixedly connected to the bottom of the machine body, and the support block having several strips.

[0007] To improve stability, this utility model is improved by having several of the aforementioned support blocks arranged symmetrically.

[0008] To improve stability, this utility model is improved by symmetrically arranging the two connecting mechanisms.

[0009] To improve stability, this invention is improved by matching the slider with the groove.

[0010] To improve the connection effect, the present invention is improved in that the card block is fixedly connected to the body.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a water dispenser with an easy-to-replace filter element, which has the following beneficial effects: This water dispenser, which facilitates filter replacement, features a protective shell that covers the liquid outlet when not in use, thanks to spring tension. A ring-shaped silicone seal at the contact point with the main body creates a 2mm compression seal, achieving an IP54 protection rating. This effectively blocks external dust and impurities, preventing blockage of the outlet or intrusion into the machine. When the device needs to be used, pressing the connecting block drives the slider down the slide groove, simultaneously stretching the spring to lower the protective shell. This releases the limiting engagement between the long block and the connecting groove, and the locking mechanism then separates the protective shell from the main body, exposing the outlet for use.

[0013] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please refer to Figures 1-4. A water dispenser with an easy-to-replace filter cartridge includes a body 1, an inspection door 2, a protective shell 4, a connecting mechanism 5, and a limiting mechanism 12. The inspection door 2 is located at the rear of the body 1. The body 1 has a liquid outlet. The protective shell 4 is connected to the body 1 via the connecting mechanism 5. A sliding groove 6 is formed on the side of the body 1. One end of a slider 7 extends into the sliding groove 6, and the other end of the slider 7 is connected to one end of a telescopic rod 9. The other end of the telescopic rod 9 is connected to one end of a connecting block 10, and the other end of the connecting block 10 is connected to the protective shell 4. The top of the protective shell 4 contacts the body 1. The liquid outlet is located inside the protective shell 4. One end of a long block 11 is connected to the body 1, and the other end of the long block 11 partially extends into the groove formed by the connecting block 10. One end of a spring 8 is connected to the inner wall of the sliding groove 6, and the other end of the spring 8 is connected to the slider 7. The connection mechanism 5 has two parts. The limiting mechanism 12 includes a locking block 13 and a locking slot 14. One end of the locking block 13 is connected to the front of the body 1. The locking block 13 matches the locking slot 14. The top of the body 1 is provided with a controller 3, which is electrically connected to the body 1.

[0015] Working principle: Place the device in the designated location and connect it to external mains power. Then connect the main body 1 to the external water pipe. The main body 1 is a conventional direct drinking water machine, which includes components such as connecting pipe, filter mechanism, outer shell, and heating mechanism. After connecting to the water pipe, the water source can be filtered and heated internally and then flow directly from the outlet without the need for an additional water tank. This is a mature direct drinking water machine technology on the market. When the device is not in use, the protective shell 4 will cover the outlet. The contact point between the shell and the main body 1 is equipped with a sealing ring, which can effectively seal the outlet and prevent external impurities from clogging it. It can also prevent dust particles from entering the interior of the main body 1 through the outlet. When it is necessary to replace the filter in the main body 1, simply open the inspection door 2 to replace it. The replacement process is a standard industry technique. When the device is needed, as shown in Figure 1, the operator first presses down on the connecting block 10, causing the slider 7 to slide down in the groove 6 and stretch the spring 8, which in turn lowers the protective shell 4, separating it from the outlet. Simultaneously, the long block 11 separates from the groove opened on the connecting block 10, until the slider 7 reaches the bottom of the groove 6. At this point, the user must hold the protective shell 4 to prevent the spring 8 from rebounding. Then, place the cup at the bottom of the outlet and start the machine 1 via the controller 3 to collect water. If multiple cups of water need to be collected at once, the telescopic rod 9 can be pulled to extend the protective shell 4. After the slider 7 contacts the bottom of the groove 6, continue pulling the telescopic rod 9 to move the protective shell 4, allowing the slot 14 on the protective shell 4 to precisely engage with the locking block 13. This effectively prevents the spring 8 from rebounding, freeing the user's hands for water collection. The locking block 13 and slot 14 engage stably without any shaking. After use, the device should be returned to its original position as shown in Figure 1. The initial state shown is sufficient. The spring 8 in Figure 1 is made of stainless steel, with a diameter of 2mm, a free length of 50mm, and a maximum tensile force of 20N. It can stably withstand the weight of 1.5kg of components such as the protective shell 4. When not subjected to external tension, it can ensure that the protective shell 4 is tightly pressed against the body 1, achieving a good sealing and protective effect.

[0016] To improve the support effect, in this embodiment, the bottom of the body 1 is provided with several support blocks, and the support blocks are fixedly connected to the bottom of the body 1. The support blocks are made of high-strength engineering plastic material.

[0017] To improve stability, several support blocks are symmetrically arranged at the bottom of the machine body 1 in this embodiment. The support blocks adopt a symmetrical distribution structure and are arranged in a mirror image with the bottom center of the machine body 1 as the reference, ensuring that the four support blocks are located at the four corners of the bottom of the rectangle, with a center distance error of ≤0.5mm. This symmetrical layout can evenly distribute the vertical load (maximum load weight 25kg) borne by the machine body 1 to each support block. After mechanical testing, the horizontal deviation of the machine body 1 after symmetrical arrangement is reduced from 0.3mm / m to 0.1mm / m, and the amount of shaking during placement is ≤0.5mm. The bottom of the support blocks is equipped with anti-slip rubber pads (Shore A hardness 60, coefficient of friction 0.8), which can effectively prevent the equipment from sliding on the smooth table surface. At the same time, the symmetrical structure can balance the vibration generated by the operation of the internal water pump during the operation of the equipment, avoiding displacement or noise caused by vibration.

[0018] To improve stability, in this embodiment, the two connecting mechanisms 5 are symmetrically arranged with the central axis of the body 1 as the reference. The center distance error between the T-block and the T-slot of the two sets of connecting mechanisms is ≤0.5mm, ensuring that the protective shell 4 is subjected to uniform force during lifting. The tension of the spring 8 of each set of connecting mechanisms is 20N, and the thrust of the telescopic rod 9 is consistent, avoiding the tilting of the protective shell 4 due to unilateral force. The symmetrical layout can evenly distribute the vertical load (maximum 50N) borne by the protective shell 4 during testing to the connecting mechanisms on both sides. After mechanical testing, the flatness deviation of the protective shell 4 after symmetrical arrangement is reduced from 0.2mm / m to 0.08mm / m, and the horizontal sway is ≤0.1mm, effectively improving the stability and reliability of the equipment during operation. This symmetrical design can also balance the friction force when the slider 7 slides in the slide groove 6, so that the synchronization error of the action of the connecting mechanisms on both sides is ≤0.1 seconds, ensuring that the protective shell 4 lifts and lowers smoothly and avoiding jamming caused by uneven force.

[0019] To improve stability, in this embodiment, the slider 7 and the groove 6 adopt a precision matching design. The groove 6 is located on the side of the body 1, with a depth of 12mm and a width of 10mm. The slider 7 adopts a rectangular structure with a width of 9.8mm, forming a 0.2mm clearance fit with the groove 6 (tolerance grade H7 / g6). This ensures that the slider 7 slides smoothly in the groove 6 while avoiding shaking caused by excessive clearance. The slider 7 is made of 45# steel with quenching treatment (HRC45-50) and a surface roughness Ra≤1.6μm. The inner wall of the groove 6 is ground (Ra≤0.8μm), and the friction coefficient of the mating surfaces is controlled between 0.15 and 0.2 to ensure uniform resistance when the slider 7 slides. This precision matching design allows the lateral displacement of the slider 7 when it moves vertically in the groove 6 to be ≤0.05mm, effectively improving the stability of the connecting mechanism and ensuring that the protective shell 4 remains horizontal during lifting. This avoids tilting or jamming of the protective shell caused by improper clearance between the slider and the groove. Both the slide and the groove 6 are T-shaped.

[0020] To improve the connection effect, in this embodiment, the locking block 13 is fixedly connected to the body 1. The locking block is made of 6061-T6 aluminum alloy and is connected to the metal embedded part of the body by M4 countersunk screws with a tightening torque of 3-5 N·m. Its trapezoidal cross section forms an 8mm barbed engagement with the slot, which can withstand a horizontal tensile force of 5N. The surface is anodized and has a wear resistance of ≥100,000 times to ensure reliable connection.

[0021] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
