Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a water dispenser. Background Technology

[0002] Currently, some water dispensers offer a tea-making function. The machine and the teapot are electrically connected via a coupler to achieve power supply and signal exchange. Furthermore, some water dispensers also feature a direct drinking water function, allowing users to fill their cups directly with water.

[0003] Because the coupler on the machine protrudes at least partially to connect electrically with the teapot, it is difficult or impossible to place a water cup at the location where the coupler is set, which affects the user experience. It is necessary to set up an additional drinking water outlet and a place to put the water cup, which is not conducive to cost control and miniaturization design of the machine. Utility Model Content

[0004] Based on the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide a water dispenser that adds a lifting component to the base assembly so that the lower coupler can switch between an extended position and a retracted position, thereby enabling the base assembly to simultaneously support the kettle and be electrically connected to it, as well as support the water cup.

[0100] The following is based on Figures 1 to 21 This utility model describes the water dispenser in detail.

[0101] In this embodiment, such as Figures 1 to 11 As shown, the water dispenser 100 includes a kettle (not shown), a base assembly 2, and a main unit. An upper coupler is located at the bottom of the kettle. The base assembly 2 includes a support base 21, a lower coupler 221, and a lifting assembly 27. The support base 21 forms a support structure and is a water collection box structure. The support base 21 includes interconnected water collection holes and a water collection cavity. The water collection holes are located on the top wall of the support base 21 to prevent water stains from remaining on the surface of the support base 21 during water dispensing. The lower coupler 221 is movably mounted on the support base 21. Figures 3 to 6 As shown, the lifting assembly 27 includes a linkage 271 and an actuator 272. The linkage 271 includes a connecting part 2711, which is rotatably connected to the support base 21. The linkage 271 is linked with the lower coupler 221.

[0102] The water dispenser 100 may further include a processor (not shown) and a power module (not shown), with a lower coupler 221 electrically connected to both the processor and the power module. In one embodiment of this application, the lower coupler 221 may be directly electrically connected to the processor and the power module via a wire. In another embodiment of this application, the water dispenser 100 may further include a connecting coupler (not shown), which is mounted in the support base 21, and the lower coupler 221 is electrically connected to the processor and the power module via the connecting coupler.

[0103] like Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, when the actuator 272 moves, the actuator 272 drives the linkage 271 to rotate, thereby causing the linkage 271 to switch between the lifting state and the lowering state.

[0104] like Figure 10 and Figure 11As shown, when the linkage 271 switches from the retracted state to the raised state, the linkage 271 drives the lower coupler 221 to move from the retracted position to the extended position. At this time, the lower coupler 221 is at least partially located above the placement surface of the support base 21. When the kettle is placed on the placement surface of the support base 21, the lower coupler 221 can achieve structural and electrical connection with the upper coupler at the bottom of the kettle. The lower coupler 221 is electrically connected to the connecting coupler so that the kettle can be electrically connected to the host (the processor and power module are set on the host). After the kettle is filled with water, it can further perform functions such as cooking and keeping warm.

[0105] like Figure 2 and Figure 3 As shown, when the linkage 271 switches from the raised state to the lowered state, the lower coupler 221 can move from the extended position to the retracted position. At this time, the placement surface of the support base 21 is higher than the highest point of the lower coupler 221. Thus, the placement surface of the support base 21 can be used to support the water cup. Alternatively, at this time, the placement surface of the support base 21 is flush with the highest point of the lower coupler 221. Thus, the placement surface of the support base 21 and the lower coupler 221 can jointly support the water cup. The user can place the water cup stably on the base assembly 2 for direct drinking water.

[0106] In the above technical solution, the base assembly 2 is equipped with a lifting component 27, which is configured with a cooperating linkage 271 and an actuator 272. This allows the linkage 271 to switch between a raised state and a lowered state. Simultaneously, since the linkage 271 is linked with the lower coupler 221, the linkage 271 enables the lower coupler 221 to switch between an extended position and a retracted position. Ultimately, the base assembly 2 simultaneously serves the dual functions of supporting the kettle and connecting it electrically, as well as supporting the water cup. This allows the water dispenser 100 to have only one water outlet, facilitating a miniaturized design. Of course, the base assembly 2 of this solution can also be applied to water dispensers with multiple water outlets.

[0107] It should be understood that, normally during the placement of the kettle, the upper coupler of the kettle is inserted vertically downwards into the lower coupler 221. Therefore, if... Figure 3 and Figure 10 As shown, the lower coupler 221 moves along the vertical direction to switch between an extended position and a retracted position.

[0108] In one implementation, such as Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the linkage 271 also includes a driven part 2712 spaced apart from the connecting part 2711. When the actuator 272 moves, the actuator 272 cooperates with the driven part 2712, causing the linkage 271 to rotate around the rotational connection between the connecting part 2711 and the support base 21, thereby switching the linkage 271 between the lifting state and the lowering state.

[0109] In one implementation, such as Figure 2 , Figure 3 , Figure 6 and Figure 11 As shown, the rotation axis of the connecting part 2711 is perpendicular to the movement direction of the lower coupler 221, which helps to increase the movement distance of the driven part 2712 in the movement direction of the lower coupler 221. This helps to ensure that the linkage 271 can meet the design requirements of the lifting and falling amplitude while minimizing the rotation angle of the linkage 271.

[0110] In one implementation, such as Figure 7 and Figure 10 As shown, when the actuator 272 pushes the driven part 2712 upward, the linkage 271 rotates to switch from the lowered state to the raised state. When the actuator 272 withdraws the upward pushing force, the linkage 271 rotates to switch from the raised state to the lowered state.

[0111] Furthermore, such as Figure 7 and Figure 10 As shown, when the actuator 272 withdraws its upward lifting force, the linkage 271 rotates under the gravity of the linkage 271 and the lower coupler 221, switching from the lifted state to the lowered state, thus simplifying the cooperation structure between the actuator 272 and the driven part 2712. Of course, when the actuator 272 withdraws its upward lifting force, the linkage 271 can also switch from the lifted state to the lowered state by the actuator 272. For example, the actuator 272 is the extension rod of a cylinder (not shown in the figure). The actuator 272 is connected to the driven part 2712. When the actuator 272 extends upward, it lifts the linkage 271; when the actuator 272 retracts downward, it pulls the linkage 271 back.

[0112] In one implementation, such as Figure 5 and Figure 6As shown, the lower coupler 221 includes a coupling electronic component 2211 and a mounting component 2212. The coupling electronic component 2211 is mounted on the mounting component 2212 and is used for electrical connection with the upper coupler. The mounting component 2212 is linked with the linkage component 271, and the mounting component 2212 and the coupling electronic component 2211 are sealed by a sealing ring 2213. By adding the mounting component 2212, the linkage component 271 is prevented from directly linking with the coupling electronic component 2211, thus avoiding damage to the coupling electronic component 2211 due to prolonged localized concentrated stress.

[0113] In one implementation, such as Figures 3 to 7 As shown, the linkage 271 also includes a linkage part 2713, which is used to link with the lower coupler 221. The linkage part 2713 is located between the connecting part 2711 and the driven part 2712, which helps to increase the distance between the connecting part 2711 and the driven part 2712. In this way, by increasing the lever arm, the actuator 272 can more easily lift the linkage 271. Of course, the location of the linkage part 2713 is not limited to this; the driven part 2712 can also be located between the connecting part 2711 and the linkage part 2713.

[0114] In one implementation, such as Figures 1 to 3 As shown, the support base 21 includes a base body 2161 and a cover body 2162. The cover body 2162 covers the base body 2161, and the two together form a cavity 218. The lifting assembly 27 is disposed in the cavity 218. The support base 21 is designed as a split structure to facilitate the quick assembly of the lifting assembly 27.

[0115] Furthermore, such as Figure 4 As shown, the bottom wall of the seat 2161 is recessed to form a first recessed structure 21611. The lifting component 27 is partially located within the first recessed structure 21611. Setting the bottom wall of the seat 2161 to have an uneven structure not only accommodates the lifting component 27 but also facilitates the miniaturization of the support seat 21. Alternatively, the lifting component 27 can be entirely located within the first recessed structure 21611. When the linkage 271 is in the lowered state, the lower coupler 221 can be partially located within the first recessed structure 21611 or entirely located outside the first recessed structure 21611.

[0116] In one implementation, such as Figure 4 As shown, one side wall of the seat 2161 is recessed to form a second recessed structure 21612. One side of the lifting component 27 is located in the second recessed structure 21612. Setting one side wall of the seat 2161 to be an uneven structure not only accommodates the lifting component 27, but also facilitates the miniaturization design of the support seat 21.

[0117] In one implementation, such as Figure 1 and Figure 4 As shown, the top of the seat 2161 has a first opening 21613, and one side of the seat 2161 has a second opening 21614. These two openings on the seat 2161 facilitate the assembly of the lifting component 27 into the cavity 218. Preferably, the top of the seat 2161 is completely open, and the side of the seat 2161 with the second opening 21614 is also completely open, providing the operator with a more convenient operating space. Figure 1 and Figure 2 As shown, the cover 2162 has a bent structure to close the first opening 21613 and the second opening 21614.

[0118] In one implementation, such as Figure 1 and Figure 4 As shown, the seat 2161 is provided with a support rib 21615, which is partially located in the first concave structure 21611, and the connecting part 2711 is rotatably connected to the support rib 21615. Of course, the support rib 21615 can also be entirely located in the first concave structure 21611.

[0119] Furthermore, such as Figure 1 and Figure 4 As shown, there are two support ribs 21615, and the connecting part 2711 is a shaft structure, which is rotatably connected to the two support ribs 21615 respectively. The top wall of the support rib 21615 has a locking hole 216151, and the connecting part 2711 is engaged downward in the two locking holes 216151 with a clearance fit. Of course, the assembly structure of the support rib 21615 and the connecting part 2711 is not limited to this. The support rib 21615 may also have a circular hole (not shown in the figure), and the connecting part 2711 passes through the two circular holes with a clearance fit between the connecting part 2711 and the hole wall.

[0120] Furthermore, such as Figure 4 As shown, the support rib 21615 gradually expands in the downward direction to improve the structural stability of the support rib 21615.

[0121] In one implementation, such as Figure 6 and Figure 9 As shown, the lower coupler 221 abuts downward against the linkage 271. Thus, when the linkage 271 switches from the lowered state to the raised state, the linkage 271 raises the lower coupler 221; when the linkage 271 switches from the raised state to the lowered state, the linkage 271 moves downward to the retracted position under its own weight and the weight of the lower coupler 221.

[0122] Furthermore, such as Figure 6 and Figure 9As shown, the lower coupler 221 abuts against the upper surface of the linkage 2713. When the linkage 271 switches between the falling state and the lifting state, the linkage 2713 and the lower coupler 221 remain in contact. Since the lower coupler 221 moves linearly in the up and down direction, in order to prevent the linkage 2713 from getting stuck with the lower coupler 221 during rotation, the linkage 2713 is allowed to slide relative to the lower coupler 221 so that the linkage 271 can rotate smoothly.

[0123] In one implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, the support base 21 is provided with a third mounting hole 21623, through which the lower coupler 221 passes. The third mounting hole 21623 is configured to guide the lower coupler 221 to move linearly in the vertical direction, ensuring that the lower coupler 221 can only move linearly in the vertical direction. Furthermore, the third mounting hole 21623 is located on the cover 2162. By restricting the movement trajectory of the lower coupler 221 through the third mounting hole 21623, it is ensured that the lower coupler 221 can accurately switch between the extended and retracted positions.

[0124] In one implementation, such as Figure 3 and Figure 5 As shown, the linkage 2713 has an elongated hole 27131, the length of which extends along a first direction a, which is perpendicular to the rotation axis of the connecting part 2711. The lower coupler 221 has an extension post 22121, which is inserted into the elongated hole 27131. When the linkage 271 rotates, the elongated hole 27131 can move relative to the extension post 22121. The elongated hole 27131 restricts the displacement of the extension post 22121 in the extension direction of the rotation axis of the connecting part 2711, which is beneficial for the lower coupler 221 to stably switch between the extended position and the retracted position.

[0125] Furthermore, such as Figure 5 As shown, the elongated hole 27131 is an oblong hole, and the extension post 22121 is a cylinder. When the linkage 271 moves to the point where the end of either end of the elongated hole 27131 contacts the extension post 22121, the contact area between the two can be increased to improve the stability of the limit.

[0126] Furthermore, such as Figure 5 and Figure 6 As shown, the lower coupler 221 has an abutment protrusion 22122, which is connected to the circumferential surface wall of the extension post 22121. The abutment protrusion 22122 abuts downward against the upper surface of the linkage part 2713, as shown. Figure 9 and Figure 10 As shown, when the linkage 271 is in the lifted state, the linkage part 2713 pushes upward to abut against the protrusion 22122, so that the lower coupler 221 is in the extended position; as Figure 6 and Figure 7 As shown, when the linkage 271 switches from the raised state to the lowered state, the abutment protrusion 22122 and the linkage part 2713 remain in contact, and the lower coupler 221 moves downward to the retracted position. Preferably, the lower surface of the abutment protrusion 22122 extends horizontally, and when the linkage 271 is in the lowered state, the upper surface of the linkage part 2713 extends horizontally, so that the linkage part 2713 can more stably support the abutment protrusion 22122.

[0127] Furthermore, such as Figure 5 and Figure 6 As shown, there are two abutment protrusions 22122. The two abutment protrusions 22122 are evenly spaced apart along the circumference of the extension post 22121. In this way, the lower coupler 221 is subjected to balanced force, which is conducive to the lower coupler 221 switching more stably between the extended position and the retracted position.

[0128] In one implementation, such as Figure 5 and Figure 6 As shown, the extension post 22121 and the abutment protrusion 22122 are both provided on the mounting member 2212, so that the lower coupler 221 is linked with the linkage member 271 through the mounting member 2212.

[0129] In one implementation, such as Figure 3 , Figure 5 and Figure 6 As shown, the linkage 271 includes a linkage part 2713, a first lever arm 2714 and a second lever arm 2715. A connecting part 2711 is provided on the first lever arm 2714, and a driven part 2712 is provided on the second lever arm 2715. The first lever arm 2714, the linkage part 2713 and the second lever arm 2715 are connected in sequence to form a space 2716. The space 2716 is used to accommodate all or part of the lower coupler 221, which is beneficial to reduce the size of the base assembly 2 in the vertical direction.

[0130] Furthermore, such as Figure 5 and Figure 6 As shown, the linkage 2713 is located below the middle of the first lever arm 2714 and the second lever arm 2715. One end of the linkage 2713 is connected to the first lever arm 2714 and the included angle between the two is an obtuse angle. The other end of the linkage 2713 is connected to the second lever arm 2715 and the included angle between the two is an obtuse angle. This helps to increase the size of the space 2716 so that more couplers 221 can be accommodated.

[0131] In one implementation, such as Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, the actuator 272 rotates to trigger the linkage 271 to rotate around the rotational connection between the connecting portion 2711 and the support base 21. Of course, the actuator 272 can also move linearly to trigger the linkage 271 to rotate around the rotational connection between the connecting portion 2711 and the support base 21; for example, the actuator 272 can be the extension rod of a cylinder.

[0132] In one implementation, such as Figure 3 and Figure 5 As shown, the lifting assembly 27 also includes a motor, which is located in the motor housing 274. The output shaft 273 of the motor extends out of the motor housing 274 to be coaxially connected with the actuator 272.

[0133] Of course, the structure of the lifting assembly 27 is not limited to this. In other embodiments (not shown in the figure), the lifting assembly 27 may include a motor, the output shaft of which directly constitutes the actuator. The linkage also includes a linkage part and a driven part, which are distributed sequentially. The centerlines of the connecting part and the driven part coincide. The linkage part is a cam structure, and its surface has a raised surface and a recessed surface. The linkage part abuts upward against the lower coupler 221. When the actuator moves, the driven part drives the connecting part to rotate around its own axis, and the linkage switches between a raised state and a lowered state. When the linkage is in the raised state, the raised surface of the linkage part abuts upward against the lower coupler, so that the lower coupler is in the extended position. When the linkage is in the lowered state, the recessed surface of the linkage part abuts upward against the lower coupler, so that the lower coupler is in the retracted position.

[0134] In one embodiment, when the actuator 272 rotates, the actuator 272 and the driven part 2712 are shaped to fit together, so that the linkage 271 rotates around the rotational connection between the connecting part 2711 and the support base 21. In this solution, the fit structure between the actuator 272 and the driven part 2712 is simple and easy to process.

[0135] Furthermore, when the actuator 272 rotates, the actuator 272 and the driven part 2712 cooperate through the cooperation of the protrusion and the groove, so that the linkage 271 rotates around the rotational connection between the connecting part 2711 and the support base 21. In this solution, the cooperation structure between the actuator 272 and the driven part 2712 is simple and easy to process.

[0136] Furthermore, such as Figure 5 and Figure 8As shown, the driven part 2712 is a downwardly extending driven protrusion. The actuator 272 is provided with an active groove 2721 and a lifting part 2722. The lifting part 2722 is higher than the active groove 2721. During the rotation of the actuator 272, the relative positions of the active groove 2721 and the lifting part 2722 with respect to the driven part 2712 will change. Specifically, when the driven part 2712 and the active groove 2721 are opposite each other in the vertical direction, that is, when the actuator 272 rotates to the point where the active groove 2721 is below the driven part 2712, the driven part 2712 extends into the active groove 2721, so that the linkage 271 is in a fallen state; when the lifting part 2722 lifts the driven part 2712 upward, that is, when the actuator 272 rotates to the point where the lifting part 2722 is below the driven part 2712, so that the linkage 271 is in a lifted state.

[0137] Furthermore, such as Figure 8 As shown, the active groove 2721 extends along the rotation direction of the actuator 272. The two ends of the active groove 2721 extend upwards at an angle, forming a first inclined surface 27211 and a second inclined surface 27212, respectively. The first inclined surface 27211 and the second inclined surface 27212 are spaced apart along the rotation direction of the actuator 272. Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, when the linkage 271 switches from the raised state to the lowered state, the driven part 2712 moves along the first inclined surface 27211. This allows the driven part 2712 to smoothly and quickly extend into the active groove 2721, thereby causing the linkage 271 to quickly switch from the raised state to the lowered state. When the linkage 271 switches from the lowered state to the raised state, the driven part 2712 moves along the second inclined surface 27212. This allows the driven part 2712 to smoothly and quickly move until its bottom wall abuts against the raised part 2722, thereby causing the linkage 271 to quickly switch from the lowered state to the raised state. Preferably, the driven part 2712 has a structure that is larger at the top and smaller at the bottom, providing structural strength while reducing the friction between the driven part 2712 and the active groove 2721.

[0138] Furthermore, such as Figure 5 and Figure 8 As shown, there are two active grooves 2721, two lifting portions 2722, and two driven portions 2712. The active grooves 2721 and the lifting portions 2722 are alternately distributed along the rotation direction of the actuator 272; the two driven portions 2712 are symmetrically arranged about the central axis of the actuator 272. In this way, every time the actuator 272 rotates 90°, the linkage 271 can switch between the raised position and the lowered position.

[0139] Of course, the specific scheme of the cooperation between the actuator 272 and the driven part 2712 through the protrusion and the groove is not limited to this. The driven part 2712 can also be configured as a driven groove (not shown in the figure) and a protruding surface (not shown in the figure), and a lifting protrusion (not shown in the figure) can be provided on the actuator 272. The structure and positional relationship between the driven groove and the protruding surface are the same as the structure and positional relationship between the active groove 2721 and the lifting part 2722 in the aforementioned embodiment. The driven groove and the active groove 2721 have opposite groove opening directions, and the lifting protrusion has the same structure as the driven part 2712 in the aforementioned embodiment but extends in the opposite direction. When the actuator 272 rotates to the point where the lifting protrusion is below the driven groove, the lifting protrusion extends into the driven groove, thereby causing the linkage 271 to be in a lowered state; when the actuator 272 rotates to the point where the lifting protrusion is below the protruding surface of the driven part 2712, the lifting protrusion pushes the protruding surface of the driven part 2712 upward, thereby causing the linkage 271 to be in a lifted state.

[0140] In one implementation, such as Figure 1 and Figure 2 As shown, the base assembly 2 also includes a switch 28, which is used to control the start and stop of the motor so that the user can adjust the position of the lower coupler 221.

[0141] Furthermore, switch 28 also includes a button 281 and a micro switch 282. Button 281 and micro switch 282 are linked, and button 281 is movably mounted on the cover 2162 of support base 21. When the motor is not turned on, pressing button 281 with external force turns on micro switch 282, thereby controlling the motor to turn on. When the motor is turned on, pressing button 281 with external force turns off micro switch 282 and controls the motor to stop running. Of course, the linkage between button 281 and micro switch 282 is not limited to this. It can also be that pressing and holding button 281 turns on micro switch 282, and releasing button 281 turns off micro switch 282.

[0142] In one implementation, such as Figure 14 As shown, the water dispenser 100 also includes a main unit, which has a main unit housing 31. The main unit housing 31 has a water outlet 311, and the support base 21 is located below the water outlet 311. The water dispenser 100 of this solution is equipped with only one water outlet 311, which can realize two functions: filling a kettle and filling a cup. This is beneficial to cost reduction and miniaturization of the whole machine.

[0143] In one embodiment, the main unit includes a raw water tank (not shown in the figure), the support base 21 is located in front of the main unit housing 31, and the raw water tank is located in the rear of the main unit housing 31, so as to reduce the lateral dimension of the whole machine.

[0144] In one implementation, such as Figure 12As shown, the support base 21 is detachably connected to the main unit. In this way, when the coupler 221 is in the retracted position, the water cup is too high to be placed on the base assembly 2. The support base 21 can be removed and the water cup can be placed directly on the table (such as a desktop).

[0145] In yet another implementation, such as Figure 12 As shown, the support base 21 is connected to the main unit via a mounting assembly 4. The mounting assembly 4 includes a moving rail 41 and a hinge 42. The moving rail 41 is mounted to the main unit, and the hinge 42 is movably mounted on the moving rail 41. The support base 21 is hinged to the main unit via the hinge 42. The support base 21 can move along the moving rail 41 to switch between a working position and a non-working position. Figure 14 As shown, when the support base 21 is in the working position, it can assist in receiving water; that is, the user can place a kettle or cup on the base assembly 2 to receive water. Figure 20 As shown, when the cup is too high to be placed on the base assembly 2, the user can drive the support base 21 to move along the moving track 41 to move it from the working position to the non-working position, as shown. Figure 21 As shown, when the support base 21 is in the non-working position, the user can manually rotate the support base 21. The support base 21 moves away from the water receiving area due to the rotation (for example, 90°), and the user can place the water cup directly on the table.

[0146] In one implementation, such as Figure 12 , Figure 14 and Figure 15 As shown, the main unit 3 includes a main unit housing 31, which has a clearance opening 312. A moving track 41 is located inside the main unit housing 31 to improve the aesthetic appearance of the water dispenser 100. A hinge 42 passes through the clearance opening 312 and is movably mounted on the moving track 41. The contour of the clearance opening 312 restricts the movement direction of the hinge 42, ensuring that the hinge 42 can only move along the extension direction of the moving track 41. Alternatively, the moving track 41 can also be located outside the main unit housing 31.

[0147] Furthermore, such as Figure 17 and Figure 19 As shown, the moving track 41 includes a first guide rail plate 411 and a second guide rail plate 412. The first guide rail plate 411 and the second guide rail plate 412 are arranged opposite to each other to form the moving track 41. The moving track 41 has a simple structure and is easy to process.

[0148] Furthermore, such as Figure 12 and Figure 19As shown, one sidewall of the clearance opening 312 extends toward the interior of the main unit housing 31 to form a first guide rail plate 411, and the other sidewall of the clearance opening 312 extends toward the interior of the main unit housing 31 to form a second guide rail plate 412. The moving track 41 is directly formed on the main unit housing 31 of the main unit 3, simplifying the assembly process. Furthermore, in order to improve the structural strength of the first guide rail plate 411 and the second guide rail plate 412, the bottom wall of the first guide rail plate 411 and the bottom wall of the second guide rail plate 412 are respectively connected to the inner bottom wall of the main unit housing 31.

[0149] In one embodiment, when the support base 21 is in the working position, the support base 21 is limited to the host 3 by the first limiting structure to restrict the support base 21 from moving in the direction away from the host housing 31. At this time, the outer wall of the support base 21 abuts against the outer wall of the host 3, and the outer wall of the host 3 can restrict the support base 21 from moving in the direction toward the host 3, thereby restricting the support base 21 from displacing in the front-back direction.

[0150] Furthermore, the support base 21 is connected to the main unit 3 through the first limiting structure to achieve limiting, which is simple in structure.

[0151] Furthermore, such as Figure 12 , Figure 13 and Figure 20 As shown, the support base 21 has an extension structure 217, and the extension structure 217 has a snap-fit ​​protrusion 2171. The main unit housing 31 of the main unit 3 has an assembly port 316. When the support base 21 is in the working position, the extension structure 217 passes through the assembly port 316 and extends into the main unit housing 31. The snap-fit ​​protrusion 2171 engages with the inner side wall of the main unit housing 31 to restrict the support base 21 from moving away from the main unit housing 31. The snap-fit ​​protrusion 2171 constitutes a first limiting structure. When the support base 21 moves from the working position to the non-working position, the snap-fit ​​protrusion 2171 is squeezed by the assembly port 316, causing the extension structure 217 to deform until the extension structure 217 exits from the assembly port 316. The support base 21 can then smoothly move from the working position to the non-working position.

[0152] To facilitate quick engagement or disengagement of the latching protrusion 2171 with the main unit housing 31, such as... Figure 13 As shown, the extension structure 217 includes a connecting arm 2172 and a hollow part 2173. The hollow part 2173 is C-shaped or U-shaped and is arranged around the connecting arm 2172 so that the connecting arm 2172 has a certain elastic deformation performance. The buckle protrusion 2171 is provided on the connecting arm 2172.

[0153] In one embodiment, when the support base 21 is in a non-working position, the support base 21 is limited to the host 3 by the second limiting structure to restrict the hinge 42 from moving in a direction away from the host housing 31, so as to prevent the hinge 42 and the support base 21 from detaching from the host 3.

[0154] Furthermore, such as Figure 19 As shown, the inner wall of the main unit casing 31 of the main unit 3 is provided with a limiting protrusion 313, which constitutes a second limiting structure, and the structure is simple. Figure 18 and Figure 20 As shown, when the support base 21 is in the non-working position, the limiting protrusion 313 restricts the hinge 42 from moving in the direction away from the main unit housing 31, thereby restricting the support base 21 from moving in the direction away from the main unit housing 31.

[0155] Furthermore, such as Figure 15 and Figure 19 As shown, the hinge 42 has an elongated hole 421, into which a limiting protrusion 313 extends. When the support 21 is in a non-working position, the limiting protrusion 313 abuts against one end of the wall of the elongated hole 421 to achieve restriction. A gap is left between the circumferential outer wall of the limiting protrusion 313 and the wall of the elongated hole 421. When the support 21 switches between the working and non-working positions, the elongated hole 421 can be displaced relative to the limiting protrusion 313.

[0156] In one implementation, such as Figure 15 As shown, the limiting protrusion 313 is provided on the inner bottom wall of the main unit housing 31. Of course, the limiting protrusion 313 can also be provided on the inner side wall of the main unit housing 31. The limiting protrusion 313 has a bent structure so as to partially extend into the elongated hole 421, thereby restricting the hinge member 42 from moving away from the main unit housing 31 when the support base 21 is not in the working position.

[0157] In one implementation, such as Figure 14 , Figure 15 and Figure 19 As shown, the main unit housing 31 includes an upper housing 314 and a bottom housing 315. The upper housing 314 and the bottom housing 315 are detachably connected, which facilitates the installation of the internal components of the main unit 3 into the main unit housing 31. The limiting protrusion 313 is provided on the inner wall of the bottom housing 315.

[0158] In one implementation, such as Figures 15 to 18As shown, the limiting protrusion 313 is provided with a threaded hole 3131. The mounting assembly 4 also includes a bolt 43 and a first washer 44. The bolt 43 passes through the first washer 44 and is screwed into the threaded hole 3131. The head of the bolt 43 presses the first washer 44 downward against one side of the outer wall of the elongated hole 421. In this design, one end of the hinge 42 is restricted by the contour of the clearance opening 312, and the other end of the hinge 42 is pressed by the first washer 44, so that the hinge 42 can move stably in the moving track 41 and prevent the hinge 42 from tilting or wobbling.

[0159] In one implementation, such as Figure 12 , Figure 15 , Figure 16 , Figure 20 and Figure 21 As shown, the hinge 42 includes a hinge shaft 422, and the support base 21 is provided with a bushing 219, which is rotatably sleeved on the hinge shaft 422.

[0160] Furthermore, such as Figures 15 to 17 As shown, the hinge 42 includes a hinge portion 423. The hinge portion 423 has a recess 4231 on the side facing the support base 21. The hinge portion 423 also has a first mounting hole 4232 and a second mounting hole 4233. The hinge shaft 422 is a bolt, and a bushing 219 is inserted into the recess 4231. The hinge shaft 422 passes through the first mounting hole 4232, the bushing 219, and the second mounting hole 4233 in sequence and is then locked by a nut 424. In this design, the recess 4231 in the hinge portion 423 can limit the movement of the hinge shaft 422, and the cavity wall of the recess 4231 can restrict the vertical displacement of the hinge shaft 422. Furthermore, configuring the hinge shaft 422 as a bolt structure facilitates quick and easy assembly of the support base 21 with the mounting assembly 4.

[0161] Furthermore, such as Figures 15 to 17 As shown, the mounting assembly 4 includes a second washer 425, a hinge shaft 422 passes through the second washer 425, and the cap of the hinge shaft 422 presses the second washer 425 against the outer wall of the hinge portion 423 to prevent the hinge shaft 422 from moving axially.

[0162] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
