[0002] With the development of drinking water equipment, it has more and more functions. The drinking water equipment includes a compressor, a heat exchanger, a refrigerant pipeline and a fan to realize the cooling or heating function of the drinking water equipment. Usually, the heat exchanger is arranged on the side of the compressor and is parallel to the rear panel of the drinking water equipment as a whole.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0034] With the development of drinking water equipment, it has more and more functions. The drinking water equipment includes a compressor, a heat exchanger, a refrigerant pipeline and a fan to realize the cooling or heating function of the drinking water equipment. Usually, the heat exchanger is arranged on the side of the compressor and is parallel to the rear panel of the drinking water equipment as a whole. The fan is arranged corresponding to the heat exchanger. In order to ensure the heat exchange effect of the heat exchanger, the fan needs to be spaced apart from the heat exchanger so that the heat exchanger as a whole falls within the exhaust range of the fan. This leads to a larger volume of the drinking water equipment. Due to the limitation of the volume of the drinking water equipment, the spatial adaptability and production efficiency of the drinking water equipment are easily affected, and thus cannot meet user needs.

[0035] In order to solve this technical problem, the utility model proposes a drinking water device. It should be noted that the drinking water device can be specifically configured as a water purifier, a water dispenser or other equipment with cooling or heating functions to meet the user's cold water or hot water needs.

[0036] The utility model provides a drinking water device.

[0037] See also Figures 1 to 5 In one embodiment of the utility model, the drinking water equipment includes a frame 1, an insulation box 7, a compressor 3, a heat exchanger 4 and a fan 6, the frame 1 includes a base 11 and a bracket 12 arranged on the base 11; the insulation box 7 is installed on the bracket 12; the compressor 3 is arranged on the base 11; the heat exchanger 4 is horizontally placed on the base 11 and is located below the compressor 3, and the base 11 is provided with a vent 113a corresponding to the heat exchanger 4; the fan 6 is horizontally placed on the base 11, and the exhaust port of the fan 6 is arranged corresponding to the vent 113a. In the horizontal direction, the cross-sectional area of ​​the heat exchanger 4 is S1, the area of ​​the vent 113a is S2, the cross-sectional area of ​​the base 11 is S3, and the 1 / 3S3≤S1≤S2.

[0038] The technical solution of the utility model is to place the heat exchanger 4 horizontally on the base 11, and the exhaust port of the fan 6 is set corresponding to the heat exchanger 4, and make S1≤S2, so that the exhaust range of the fan 6 can cover the entire heat exchanger 4, thereby ensuring that the fan 6 can accelerate the heat exchange effect of various parts of the heat exchanger 4, thereby avoiding the local heat exchange unevenness of the heat exchanger 4, and further avoiding the situation where the local temperature of the heat exchanger 4 is too high.

[0039] Next, since the base 11 is also used for installing the compressor 3 and the bracket 12 , the present solution sets 1 / 3S3≤S1, which can avoid interference between the installation of the compressor 3 and the bracket 12 and the heat exchanger 4 .

[0040] Secondly, since the fan 6 and the heat exchanger 4 are placed horizontally on the base 11 and are located below the compressor 3, it is possible to avoid having the heat exchanger 4 and the fan 6 be arranged on the side of the compressor 3, thereby reducing the lateral space of the drinking water equipment. Moreover, since the vent 113a of the present solution is greater than or equal to the area of ​​the heat exchanger 4, the exhaust port of the fan 6 is arranged corresponding to the vent 113a, that is, the exhaust area of ​​the fan 6 is greater than or equal to the area of ​​the heat exchanger 4. Therefore, the fan 6 and the heat exchanger 4 can be arranged close to each other, which is beneficial to reducing the longitudinal space of the drinking water equipment, and further beneficial to improving the miniaturization level of the drinking water equipment.

[0041] Furthermore, the cross-sectional area S1 of the heat exchanger 4 may also be greater than or equal to 2 / 5 S3, which can further improve the heat exchange effect of the heat exchanger 4 and make the structure of the drinking water equipment more compact.

[0042] In the technical solution of the utility model, the heat exchanger 4 and the fan 6 are installed in the base 11 and arranged in sequence below the compressor 3. The heat exchanger 4 and the fan 6 are arranged in the longitudinal direction of the base 11 and are both arranged horizontally. Compared with arranging the heat exchanger, the fan and the compressor along the horizontal direction of the drinking water equipment, the space in the base 11 is reasonably utilized, and the space occupied by the drinking water equipment in the horizontal direction can be effectively reduced, ensuring that the overall volume of the base 11 is as small as possible, which can improve the integration level and miniaturization level of the drinking water equipment, and further improve the spatial adaptability of the drinking water equipment, so that the drinking water equipment can be applied to related equipment with refrigeration requirements, which helps to improve production efficiency and reduce production costs.

[0043] In this embodiment, the heat exchanger 4 is configured as a condenser, the drinking water device further includes an evaporator and a tank body, the heat preservation box 7 includes a box body and a box cover, a heat preservation cavity is formed in the box body and the box cover, the evaporator is wrapped around the outer peripheral surface of the tank body, and the evaporator and the tank body are both located in the heat preservation cavity, and the box cover is arranged at the opening of the box body. The heat preservation box 7 is provided to reduce the situation where the evaporator absorbs too much external heat, thereby reducing its cooling effect; at the same time, the heat preservation box 7 can also maintain the temperature of the cold drink in the tank body, preventing the cold drink in the tank body from returning to normal temperature too quickly, thereby reducing the energy consumption of the drinking water device and improving the user experience.

[0044] Of course, in other embodiments, when the heat exchanger 4 is configured as an evaporator, the water device further includes a condenser and a tank body, and the heat preservation box 7 includes a box body and a box cover. A heat preservation cavity is formed in the box body and the box cover. The condenser is wrapped around the outer peripheral surface of the tank body, so as to achieve heating treatment of water or other beverages in the tank body. The liquid in the tank body is heated to a set temperature through the condenser, and then flows through the water nozzle outlet and falls into the user's cup to achieve the function of discharging hot water. The condenser and the tank body are both located in the heat preservation cavity, and the box cover is provided at the opening of the box body. The heat preservation box 7 is provided to reduce the heat diffusion of the condenser to the outside, thereby reducing its heating effect; at the same time, the heat preservation box can also maintain the temperature of the hot drink in the tank body, prevent the hot drink in the tank from returning to normal temperature too quickly, and improve the user experience.

[0045] It can be understood that the compressor 3, the condenser and the evaporator are connected end to end in sequence to realize the circulation of the refrigerant. The compressor 3 sucks the low-temperature and low-pressure refrigerant into the compression chamber, and then compresses the refrigerant into a high-pressure and high-temperature gas through mechanical compression; the high-pressure and high-temperature refrigerant gas is sent to the condenser and becomes a high-pressure liquid through heat release and condensation; the high-pressure liquid then passes through the throttling and pressure-reducing effect of the throttle valve, and is instantly cooled and becomes a low-pressure liquid, and enters the evaporator; in the evaporator, the low-pressure liquid contacts the external air or liquid, absorbs the external heat and vaporizes to become a low-temperature and low-pressure gas; the low-temperature and low-pressure gas is sucked into the compressor 3 for compression again, and this reciprocating cycle continuously absorbs heat from the air to achieve a cooling effect.

[0046] Reference Figures 2 to 5 In this embodiment, the base 11 includes a first mounting portion 11a and two second mounting portions 11b located on opposite sides of the first mounting portion 11a. The first mounting portion 11a is used for mounting the heat exchanger 4 and the fan 6, and the second mounting portion 11b is used for mounting the compressor 3 and the bracket 12. It can be understood that the base 11 is divided into the first mounting portion 11a and the two second mounting portions 11b, and the fan 6 and the heat exchanger 4 are arranged on the first mounting portion 11a, which is conducive to the longitudinal arrangement of the heat exchanger 4 and the fan 6, and the compressor 3 and the bracket 12 are installed on the second mounting portions 11b located on opposite sides of the first mounting portion 11a. In this way, the installation structure of the compressor 3 and the bracket 12 can be avoided from interfering with the heat exchanger 4 and the fan 6. Through reasonable spatial layout, the overall volume of the base 11 is ensured to be as small as possible to improve the integration level and miniaturization level of the drinking water equipment.

[0047] Furthermore, in this embodiment, the bracket 12 is screwed to the second mounting portion 11b. Since the installation process of the screw connection is simple, the installation efficiency of the bracket 12 and the second mounting portion 11b can be improved, and the fastening screw material used in the screw connection is easy to purchase and inexpensive, which is conducive to reducing the cost of the drinking water equipment. Of course, the utility model is not limited to this. In other embodiments, the bracket 12 can also be clamped to the second mounting portion 11b.

[0048] Reference Figure 4 and Figure 4Specifically, each of the two second mounting portions 11b is provided with a mounting column 117, and the mounting column 117 extends in a direction close to the first mounting portion 11a, and the bracket 12 is connected to the second mounting portion 11b through the mounting column 117; since the mounting column 117 extends in a direction close to the first mounting portion 11a, the tightening direction of the screw is from the second mounting portion 11b to the first mounting portion 11a, and since no other structure is provided on the side of the second mounting portion 11b away from the first mounting portion 11a, when tightening the fastening screw, there is no interference of parts with the tightening operation of the fastening screw, thereby improving the installation efficiency.

[0049] Secondly, the mounting post 117 is arranged on a side of the second mounting portion 11b away from the first mounting portion 11a, so as to ensure the distance between the fastening screw and the second mounting portion 11b, thereby preventing the fastening screw from damaging the heat exchanger 4 during the tightening process when the fastening screw is too long.

[0050] In one embodiment, the bracket 12 is arranged in a U-shape, and a mounting step 115 is provided on the side of the second mounting portion 11b away from each other, and the two opposite support arms of the bracket 12 are both abutted against and mounted on the corresponding mounting steps 115. The two opposite support arms of the bracket 12 are both provided with mounting holes, and the mounting posts 117 are arranged on the wall surface of the mounting steps 115. On the one hand, the bracket 12 is screwed and locked by the matching screw connection between the screw connection member and the mounting hole and the mounting post 117, and on the other hand, the lower end surface of the bracket 12 abuts against the mounting step 115, thereby increasing the stability of the connection between the bracket 12 and the base 11.

[0051] Specifically, the mounting step 115 is provided with a limiting groove, and the two supporting arms are provided with a limiting convex rib on the opposite side. The limiting convex rib extends along the length direction of the supporting arm. When the supporting arm abuts and is mounted on the mounting step 115, the limiting convex rib is limited in the corresponding limiting groove. The limiting convex rib and the limiting groove can not only limit the bracket 12, but also prevent the bracket 12 from lateral deviation. At the same time, the limiting convex rib also enhances the structural strength of the bracket 12, reduces the possibility of deformation of the bracket 12, and thus improves the stability of the drinking water equipment.

[0052] A foot pad 34b is provided between the compressor 3 and the top surface of the second mounting portion 11b, and the compressor 3 is provided with a foot plate. In this case, the foot pad 34b can be configured as a shock-absorbing pad, which is convenient for fasteners to pass through the foot plate, the shock-absorbing pad and the second mounting portion 11b in sequence, so that the compressor 3 can be assembled on the second mounting portion 11b and the shock-absorbing effect can be ensured. The foot plate is fixed to the bottom of the compressor 3, so that the foot plate and the compressor 3 are an integrated structure.

[0053] Furthermore, a foot pad is also provided between the foot plate and the compressor 3. In this case, the foot pad can be configured as an elastic protrusion, with one end fixed on the foot plate and the other end embedded in the compressor 3, which helps to further enhance the overall shock absorption effect and improve vibration transmission.

[0054] In an embodiment of the utility model, weight-reducing holes are provided on the base 11, so that the overall weight of the drinking water equipment can be reduced by providing weight-reducing holes while ensuring that the base 11 has better stability and structural strength, wherein a plurality of weight-reducing holes are provided and distributed on the opening edge of the installation cabin 113; the weight-reducing holes may be blind holes, or may pass through and be connected to the ventilation cabin 111, and the weight-reducing holes may also be provided on the second installation portion 11b.

[0055] In some embodiments, the first mounting portion 11a is provided with a mounting cabin 113, the heat exchanger 4 is disposed in the mounting cabin 113, and the vent 113a is disposed at the bottom of the mounting cabin 113; it can be understood that the mounting cabin 113 can protect the heat exchanger 4. Of course, the present invention is not limited thereto, and in other embodiments, the heat exchanger 4 can also be directly mounted on the upper surface of the first mounting portion 11a.

[0056] Furthermore, the first mounting portion 11a is also provided with a fan compartment 111, which is located below the mounting compartment 113 and is connected through the vent 113a. The fan 6 is installed in the fan compartment 111, which can not only protect the fan 6 but also improve the integration. Moreover, the mounting compartment 113 is connected with the fan compartment 111 through the vent 113a, that is, the airflow generated by the fan 6 can directly act on the heat exchanger 4 through the vent 113a, thereby improving the heat exchange efficiency of the heat exchanger 4, and can also effectively change the temperature difference between the compressor 3 and the surrounding air, thereby improving the overall heat exchange efficiency. The horizontal placement of the heat exchanger 4 is mainly relative to the existing upright placement of the heat exchanger 4, and the horizontal placement of the fan 6 makes the exhaust direction of the fan 6 parallel to the longitudinal direction of the drinking water equipment, thereby making the base 11, the heat exchanger 4 and the fan 6 compact and reducing the overall volume.

[0057] In this embodiment, the heat exchanger 4, the base 11 and the fan 6 are arranged in a square shape. It can be understood that the square base 11 has good stability: the square base 11 is composed of four equal right-angled sides. This structure enables it to provide a larger bottom support area, so it can be better and more stably fixed on the ground. Secondly, the square base 11 occupies a small space: although the square base 11 may look larger in size, due to its compact design, it can usually use space more efficiently. Compared with bases 11 of other shapes, the square base 11 can usually provide more stable support when occupying the same area. Next, the square base 11 is easy to install and position: the four corners of the square base 11 make it easier to install and position the device. These corners can be used as reference points to help users quickly and accurately place the device and ensure that it is in a horizontal state.

[0058] The heat exchanger 4 is also arranged in a square shape, and can be matched with the square base 11, so as to reasonably utilize the space of the base 11, improve the effective space utilization rate of the base 11, and thus help to reduce the volume of the drinking water device. Next, the fan 6 is also arranged in a square shape, so that the utilization rate of the exhaust range of the fan 6 can be improved, thereby reducing the volume of the fan 6.

[0059] Reference Figure 3 Furthermore, the heat exchanger 4 is provided with a positioning ear 441, and the bottom of the installation cabin 113 is provided with a positioning column 112 connected to the positioning ear 441, so that the connection strength between the heat exchanger 4 and the first installation part 11a can be enhanced, and at the same time, the risk of damage caused by shaking of the heat exchanger 4 in the installation cabin 113 can be reduced, thereby extending the service life of the heat exchanger 4.

[0060] The connection methods between the positioning ear 441 and the positioning column 112 include but are not limited to bolt connection, plug-in connection, and snap connection.

[0061] Optionally, in this embodiment, the drinking water device further includes a mounting frame 44, the heat exchanger 4 is mounted in the mounting frame 44, and the positioning ears 441 are arranged on opposite sides of the mounting frame 44, which can improve the installation stability of the heat exchanger 4. Furthermore, the mounting frame 44 and the heat exchanger 4 are integrated, which can improve the assembly efficiency of the drinking water device.

[0062] It should be noted that, when the heat exchanger 4 is installed in the installation frame 44 , S1 refers to the horizontal cross-sectional area of ​​the heat exchanger 4 , rather than the overall horizontal cross-sectional area of ​​the heat exchanger 4 and the installation frame 44 .

[0063] Moreover, in an embodiment of the utility model, a heat exchange hole is provided on the side of the installation frame 44 facing the fan 6, wherein the heat exchange hole can be docked with the vent 113a on the installation cabin 113, ensuring that the airflow generated by the fan 6 can directly act on the heat exchanger 4 to achieve high-quality heat exchange.

[0064] Optionally, the heat exchanger 4 includes a multi-layer heat exchange tube row arranged in a vertical direction, and a transfer tube connecting two adjacent heat exchange tube rows. It can be understood that the multi-layer heat exchange tube row arranged in a vertical direction is connected by a corresponding transfer tube to form a heat exchange tube, which can not only reduce the risk of refrigerant leakage, but also increase the contact area between the heat exchanger 4 and the air by the multi-layer heat exchange tube row arranged in a vertical direction, thereby improving the heat exchange capacity of the heat exchanger 4; the heat exchange capacity of the heat exchanger 4 can be enhanced to a certain extent by extending the overall length of the heat exchange tube and extending the time the refrigerant stays in the heat exchange tube. At the same time, due to the bending setting of the heat exchange tube, the overall volume of the heat exchanger 4 can be reduced on the basis of the same heat exchange effect, which helps to achieve the miniaturization of the heat exchanger 4. Of course, in other embodiments, when the heat exchange demand is low, the heat exchanger 4 only includes a single-layer heat exchange tube row.

[0065] The tube bodies of two adjacent heat exchange tube rows are staggered in the vertical direction, which can increase the contact area between the tube body and the air at normal temperature, thereby improving the heat exchange effect of the heat exchanger 4.

[0066] In order to ensure the heat exchange effect of the heat exchanger 4 and the reliable deformation of the foot pad 34b, in the embodiment of the utility model, the minimum distance between the compressor 3 and the heat exchanger 4 is greater than or equal to 6mm and less than or equal to 10mm. It can be understood that when the distance between the compressor 3 and the heat exchanger 4 is too small, that is, less than 6mm, the gap between the heat exchanger 4 and the compressor 3 is small, which is not conducive to heat exchange, and the structure is easily damaged due to the small distance. Moreover, the heat discharged by the heat exchanger 4 will also act on the compressor 3; when the distance between the compressor 3 and the heat exchanger 4 is too large, that is, greater than 10mm, the heat dissipation gap between the heat exchanger 4 and the compressor 3 is large, which is not conducive to the miniaturization of the drinking water equipment. Therefore, limiting the minimum distance between the compressor 3 and the heat exchanger 4 to between 6mm and 10mm can not only ensure the heat exchange demand of the heat exchanger 4, but also realize the miniaturization of the drinking water equipment.

[0067] In some embodiments, the base 11 is provided with a draw-out opening 111a and a fan cabin 111 connected to the draw-out opening 111a, and the draw-out opening 111a is used for drawing the fan 6. The fan cabin 111 is used to accommodate the fan 6, and the draw-out opening 111a is provided on the side cavity wall of the fan cabin 111. Furthermore, since the draw-out opening 111a is connected to the fan cabin 111, the fan 6 can be smoothly drawn out of the fan cabin 111 by avoiding the draw-out opening 111a, thereby realizing the lateral drawing of the fan 6.

[0068] Reference Figure 7 In an embodiment of the utility model, a plurality of hanging arms 114 are arranged in the fan compartment, and the hanging arms 114 jointly support the fan 6 and allow the fan 6 to slide, thereby ensuring that the fan 6 is reliably accommodated in the fan compartment 111 and facilitating the sliding movement of the fan 6 relative to the base 11.

[0069] The fan 6 is supported by the hanging arm 114, and the fan 6 can be suspended in the fan compartment 111, which can not only reduce the material used to support the fan 6 and reduce the overall weight of the base 11, but also leave a gap between the fan 6 and the ground to facilitate the in and out of airflow and improve the heat dissipation effect.

[0070] Specifically, in an embodiment of the present utility model, the hanging arm 114 includes a connecting arm and a bearing arm, one end of the connecting arm is connected to the top wall of the cavity of the fan compartment, and the other end is connected to the bearing arm, and the bearing arm is used to support the fan 6. The hanging arm 114 is L-shaped, and the bearing arm extends laterally along the base 11 and can abut against the bottom of the fan 6. The connecting arm extends longitudinally along the base 11 and is located on the side of the fan 6. A sliding gap is arranged between the connecting arm and the fan 6 to improve the convenience of pulling and pulling the fan 6.

[0071] It should be noted that the longitudinal extension of the connecting arm is used to control the distance between the load-bearing arm and the bottom of the installation cabin 113, so as to adapt to the thickness of the fan 6 and ensure the reliable storage of the fan 6. Of course, the length of the connecting arm may be slightly larger than the thickness of the fan 6 to reduce the friction between the fan 6 and the partition; and reinforcing ribs are provided on the side of the connecting arm away from the load-bearing arm, which can improve the structural stability of the hanging arm 114, thereby ensuring the stable support of the hanging arm 114 to the fan 6.

[0072] More specifically, in the embodiment of the present invention, each of the hanging arms 114 is symmetrically arranged, and forms a channel adapted for the installation and sliding of the fan 6, that is, a channel for the installation and sliding of the fan 6 is formed between each of the hanging arms 114 and the bottom of the installation cabin 113, and because each of the hanging arms 114 is symmetrically arranged, the force uniformity of the fan 6 can be ensured, thereby improving the sliding stability of the fan 6;

[0073] The hanging arms 114 located on the same side of the channel are arranged at intervals, and at least some of the carrying arms are provided with guiding slopes. On the one hand, on the basis of ensuring the stability of the installation and sliding of the fan 6, the spacing of the hanging arms 114 is used to reduce the overall weight. On the other hand, since the hanging arms 114 are arranged at intervals, the fan 6 is guided to slide on the upper surface of each carrying arm by providing guiding slopes on the carrying arms, wherein the guiding slopes are provided on the side of the upper surface of the carrying arm close to the pull-out opening 111a, which can reduce the risk of the fan 6 tilting and directly colliding with the next hanging arm 114 during the process of sliding to the next hanging arm 114 when the fan 6 extends into the channel, and cannot smoothly move to the upper surface of the carrying arm. Of course, each carrying arm is provided with a guiding slope, or only one or two carrying arms close to the pull-out opening 111a are provided with a guiding slope, which can ensure the smooth sliding of the fan 6. In addition, in other embodiments, a guiding slope can also be provided on the side of the upper surface of the carrying arm away from the pull-out opening 111a.

[0074] Reference Figure 3 and Figure 6 In an embodiment of the utility model, the fan 6 includes a mounting seat 61 and a fan body 62, the mounting seat 61 is movably connected to the base 11, and the fan body 62 is fixed to the mounting seat 61. In this way, the mounting seat 61 is used as a transition structure between the base 11 and the fan body 62, so as to avoid the fan body 62 being directly connected to the base 11 and affecting the stable operation and structural stability of the fan body 62, thereby ensuring the efficient operation of the fan body 62; and the mounting seat 61 and the fan body 62 are fixed as a whole, which is convenient for the assembly and subsequent movable operation of the fan 6 without affecting the fan body 62 itself.

[0075] Furthermore, the mounting seat 61 is provided with an exhaust port, which is connected to the vent 113a, that is, the airflow generated by the fan 6 can directly act on the heat exchanger 4 through the exhaust port, the vent 113a and the heat exchange port in sequence, thereby improving the heat exchange efficiency of the heat exchanger 4, and can also effectively change the temperature difference between the compressor 3 and the surrounding air, thereby improving the overall heat exchange efficiency.

[0076] In some embodiments, the fan 6 has a limiting portion 612 protruding laterally, and the inner wall of the drawer opening 111 a is provided with a stopper 111 c , and the limiting portion 612 is detachably connected to the stopper 111 c . On the one hand, when the fan 6 extends into the fan compartment 111, the limit portion 612 abuts against the stop portion 111c to limit the further sliding of the fan 6, thereby reducing the risk of collision between the fan 6 and the base 11; on the other hand, by reserving a position for auxiliary fixing and pulling, the limit portion 612 and the stop portion 111c can be fixedly connected during use of the drinking water device to reduce the risk of the fan 6 being separated from the mounting seat 61 and resulting in poor heat dissipation; during maintenance, the limit portion 612 and the stop portion 111c can be separated to facilitate the maintenance and replacement of the fan body 62; and because the limit portion 612 protrudes from the mounting seat 61, it is also convenient to pull the fan 6 to a certain extent, wherein two limit portions 612 are provided, and are arranged on opposite sides of the mounting seat 61 to balance the force of the fan 6 on the base 11 and ensure reliable assembly.

[0077] Specifically, in one embodiment, the limiting portion 612 is connected to the stop portion 111c by a fastener. It can be understood that the fastener can be configured as a screw. At this time, the limiting portion 612 and the stop portion 111c are respectively provided with a first fastening hole and a second fastening hole that are connected to each other. The screw is passed through the first fastening hole and the second fastening hole to realize the series connection of the limiting portion 612 and the stop portion 111c, thereby realizing the relative fixation of the fan 6 and the base 11, and also facilitating the disassembly and assembly of the fan 6 and the base 11.

[0078] In another embodiment, the limiting portion 612 and the stopping portion 111c are snap-connected. It can be understood that a buckle may be provided on one of the limiting portion 612 and the stopping portion 111c, and a bayonet may be provided on the other. The relative fixation of the fan 6 and the base 11 can be achieved by snap-fitting the buckle and the bayonet.

[0079] In another embodiment, the limiting portion 612 is connected to the stopping portion 111c via a fastener, and the limiting portion 612 and the stopping portion 111c are snap-fitted, which helps to strengthen the reliable connection between the limiting portion 612 and the stopping portion 111c.
