Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifiers, in particular to a water purifier. BACKGROUND

[0002] The water dispenser equipped with high-efficiency filtering function becomes the only choice of many hotels, aiming to provide safe and clean drinking water source for guests, meet their basic living needs and highlight the environmental protection of the hotel.

[0003] However, the current water dispenser in the market is not perfect, and there is a common defect that is the lack of filter protection mechanism. For example, the cover for covering the filter of the common water dispenser often lacks effective locking or protection design, so that anyone can easily open it. This convenience becomes the "culprit" of filter pollution in some improper use scenarios. Whether it is opened by curious children for fun or not closed in time due to negligence in daily maintenance. And the filter, as the core component of the water purifier, once contaminated, not only will greatly reduce its filtering effect and cannot effectively remove harmful substances in water, but also may breed bacteria, algae and other microorganisms, thereby posing a serious threat to the quality and safety of drinking water. Over time, the health risks of guests are a concern, and the reputation and image of the hotel will also be negatively affected, which is undoubtedly contrary to the original intention of introducing the water dispenser to improve service quality and environmental image.

DETAILED DESCRIPTION

[0035] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in conjunction with the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] In the description of the application, it should be understood that, if there are these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0037] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0039] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" of the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] See Figures 1 to 5 As shown, a water purifier 100 according to some embodiments of this application includes a housing 1, a cover plate 2, and a locking mechanism 4. The housing 1 and the cover plate 2 are detachably assembled and disassembled; that is, the cover plate 2 can be assembled onto the housing 1 to cover the receiving space 10 within the housing 1, and the cover plate 2 can also be detached from the housing 1, thus opening the receiving space 10. When the cover plate 2 is assembled onto the housing 1, the locking mechanism 4 can lock the cover plate 2 onto the housing 1, preventing its detachment, and can also unlock the cover plate 2 from the housing 1, allowing it to be detached. Therefore, the water purifier 100 according to this application includes a locking mechanism 4 to achieve a selective fixed connection between the cover plate 2 and the housing 1.

[0042] The water purifier 100 also includes at least one filter element, which is located in the receiving space 10. When the locking mechanism 4 fixes the cover plate 2 to the housing 1, the cover plate 2 cannot be removed from the housing 1, meaning it covers the receiving space 10, thus effectively protecting the filter element located in the receiving space 10. It should be noted that the water purifier 100 may contain one or more filter elements.

[0043] It is important to understand that, see Figure 1 As shown, in the description of this application, all descriptions are based on the water purifier 100. Figure 1 Taking the center direction as an example, where... Figure 1 The following is an example of how the X direction represents the length of the water purifier 100, the Y direction represents the width of the water purifier 100, and the Z direction represents the height of the water purifier 100.

[0044] For example, in one embodiment of this application, see [reference]. Figure 1As shown, a receiving space 10 is provided inside the housing 1, with the opening of the receiving space 10 located at the upper end of the housing 1. A cover plate 2 is adapted to be fitted onto the upper end of the housing 1. Through the cooperation between the cover plate 2 and the housing 1, the cover plate 2 can cover the opening of the receiving space 10, achieving the effect of opening and closing the receiving space 10. It should be noted that the receiving space 10 can be used to accommodate components of the water purifier 100. It is worth noting that... (Refer to...) Figure 2 As shown, the receiving space 10 can be divided into filter cartridge slots 10a for placing filter cartridges, that is, the filter cartridges are assembled in the receiving space 10. It should be noted that the size of the filter cartridge slots 10a can be specifically set according to the number of filter cartridges installed in the water purifier 100.

[0045] The purified water tank 541 stores purified water. This water, after passing through heating elements, is then supplied to the user. If the purified water tank 541 becomes contaminated, the user's water safety cannot be guaranteed. Therefore, if... Figure 6 As shown, the storage space 10 is also used to house the purified water tank 541 to further ensure the user's water safety.

[0046] See Figure 1 and Figure 3 As shown, in this embodiment, a locking mechanism 4 is provided, and the locking mechanism 4 is provided on the cover plate 2. When the cover plate 2 is assembled onto the housing 1, the locking mechanism 4 can engage with the housing 1 to lock and fix the cover plate 2 to the housing 1. However, it should be noted that in other embodiments of this application, the water purifier 100 may be equipped with multiple locking mechanisms 4; for example, two, three, four, or five locking mechanisms 4 may be provided.

[0047] Furthermore, the locking mechanism 4 is not limited to being installed only on the cover plate 2; it can also be installed on the body housing 1. For the locking mechanism 4 installed on the body housing 1, it is suitable for limiting and cooperating with the cover plate 2, thereby achieving the effect of locking and fixing the cover plate 2 to the body housing 1. It should also be noted that when the water purifier 100 is configured with multiple locking mechanisms 4, these mechanisms can be entirely arranged on the body housing 1 or the cover plate 2, or a portion of the locking mechanisms 4 can be arranged on the body housing 1, while another portion can be arranged on the cover plate 2.

[0048] During the process of installing or removing the cover plate 2 onto the fuselage housing 1, the cover plate 2 has a movement trajectory relative to the fuselage housing 1. This can also be understood as the cover plate 2 moving relative to the fuselage housing 1 along this movement trajectory during installation or removal. (See also...) Figures 1 to 3As shown, in this embodiment, the water purifier 100 also includes a sliding engagement mechanism. The cover plate 2 and the body housing 1 move relative to each other through the sliding engagement mechanism, so that the cover plate 2 can be installed and removed from the body housing 1.

[0049] More specifically, in this embodiment, combined with Figure 2 and Figure 3 As shown, the sliding engagement mechanism includes a first sliding limiting part 31 and a second sliding limiting part 32. The first sliding limiting part 31 is selected as a slot, and the second sliding limiting part 32 is selected as a buckle adapted to the slot. The buckle can slide within the slot and also provides a limiting engagement effect. It should be noted that in the embodiments of this application, the first sliding limiting part 31 is selected as a slot, and the second sliding limiting part 32 is selected as a buckle. However, this application is not limited to this. In another embodiment of this application, the first sliding limiting part 31 can be selected as a buckle, and the second sliding limiting part 32 can be selected as a slot.

[0050] See Figure 1 and Figure 2 As shown, in the upper region of the fuselage housing 1, slots (i.e., first sliding limiting parts 31) are respectively provided on the left and right sides of the fuselage housing 1. The slot on the left side of the fuselage housing 1 has an area open to the top and left, and correspondingly, the slot on the right side of the fuselage housing 1 has an area open to the top and right. (See also...) Figure 3 As shown, a corresponding buckle (i.e., the second sliding limit part 32) is provided on the inner side of the edging 21 of the cover plate 2. It should be further noted that... Figure 3 Only the buckle that fits into the slot located on the right side of the housing 1 is shown.

[0051] Combination Figures 1 to 3As shown, taking the assembly of cover plate 2 with the body housing 1 as an example, during the assembly process of cover plate 2 and body housing 1 (i.e., the process of cover plate 2 fastening to body housing 1 along the disassembly and assembly trajectory), in the height direction of the water purifier 100, the operator places cover plate 2 and body housing 1 correspondingly so that the buckle can move from the open area in the slot into the slot. The operator can then fasten cover plate 2 to the upper end of body housing 1, so that the buckle is located in the slot. Then, the operator pushes cover plate 2 forward relative to body housing 1, causing the buckle to move further into the slot. Furthermore, during the forward movement of cover plate 2 relative to body housing 1, the buckle is also adapted to abut against and limit the movement of cover plate 2 in the direction of movement, to prevent cover plate 2 from moving excessively forward, so that cover plate 2 stops at the preset assembly completion position. Additionally, it should be noted that when the buckle is further moved into the slot, the body housing 1 limits the buckle in the height and width directions of the water purifier 100. This can also be understood as the body housing 1 limiting the cover plate 2 in the height and width directions of the water purifier 100.

[0052] Therefore, in this embodiment, when the cover plate 2 stops at the preset assembly completion position, the cover plate 2 can only move backward relative to the body housing 1 along the length direction of the water purifier 100.

[0053] As can be seen from the above, for example, when the first sliding limiting part 31 is selected as one of the buckle and the slot, and the second sliding limiting part 32 is selected as the other of the buckle and the slot, the disassembly and assembly movement trajectory includes a connected first movement direction segment and a second movement direction segment, and the first movement direction segment and the second movement direction segment are in the same plane, and an angle is formed between the first movement direction segment and the second movement direction segment. More specifically, the first movement direction segment extends along the height direction of the water purifier 100, and the second movement direction segment extends along the length direction of the water purifier 100, that is, a 90-degree angle is formed between the first movement direction segment and the second movement direction segment; in other words, the first movement direction segment and the second movement direction segment are perpendicular to each other.

[0054] Next, please combine... Figures 1 to 5 As shown, the locking mechanism 4 includes a locking member 41, which is movably assembled to the cover plate 2 along the locking member movement trajectory S1. The locking member movement trajectory S1 has a locking position and an unlocking position. The locking member 41 is used to reciprocate between the locking position and the unlocking position. It can also be understood that by driving the locking member 41 to move, the locking member 41 can move along the locking member movement trajectory S1 to switch between the locking position and the unlocking position.

[0055] See Figure 4 and Figure 5 As shown, Figure 4 and Figure 5This shows the relative positional relationship between the locking member 41 mounted on the cover plate 2 and the fuselage housing 1 when the cover plate 2 is in the assembled position. Figure 4 The diagram shows a schematic of the locking member 41 in the locking position. Figure 5 The diagram shows a schematic of the locking element 41 in the unlocked position.

[0056] See Figure 4 and Figure 5 As shown, the locking member 41 is provided with a first limiting part 411, which is used to limit and cooperate with the second limiting part 11 of the body housing 1. In this embodiment, the second limiting part 11 is a groove. When the locking member 41 is in the locked position, the first limiting part 411 extends into the second limiting part 11 (the second limiting part 11 is a groove). Thus, in the length direction of the water purifier 100, the first limiting part 411 is adapted to abut against the second limiting part 11. Therefore, when the cover plate 2 is subjected to an external force and has a tendency to move backward along the length direction of the water purifier 100, since the first limiting part 411 and the second limiting part 11 play a limiting role in the length direction of the water purifier 100, the cover plate 2 cannot slide backward relative to the body housing 1. This achieves locking the cover plate 2 relative to the body housing 1 in the assembled position. This prevents the cover plate 2 from being removed from the body housing 1.

[0057] Since the cover plate 2 is locked to the housing 1, it is impossible to remove the cover plate 2 from the housing 1, and therefore it is impossible to open the receiving space 10. This protects the filter element placed in the receiving space 10 and effectively prevents the filter element from being contaminated by human factors.

[0058] Additionally, see Figure 5 As shown, when the locking member 41 moves to the unlocked position along the locking member movement trajectory S1, that is, the first limiting part 411 of the locking member 41 moves out of the second limiting part 11 (the second limiting part 11 is a groove), thereby releasing the limiting effect of the second limiting part 11 on the first limiting part 411 (that is, when the locking member 41 is in the unlocked position, the cover plate 2 is allowed to move relative to the body housing 1 along the second movement direction segment). In this way, the cover plate 2 moves backward relative to the body housing 1 under the action of external force, and then the cover plate 2 moves relative to the body housing 1 along the first movement direction segment, that is, the cover plate 2 is lifted along the height direction of the water purifier 100, so that the cover plate 2 is separated from the body housing 1. This achieves the effect of the cover plate 2 opening the receiving space 10, so that the filter element placed in the receiving space 10 can be replaced.

[0059] It should be further noted that in the above embodiment, the structure of the second limiting part 11 is described as a groove, but this application is not limited to this. In other embodiments of this application, the structure of the second limiting part 11 can be configured as a baffle. It is worth noting that, regarding the second limiting part 11, its function is to block and limit the movement of the water purifier 100 in the length direction when the locking member 41 is in the locked position. This application does not impose specific limitations on the structural shape of the second limiting part 11.

[0060] It is important to understand that the second limiting part 11, as referred to here, acts as a blocking and limiting element in the length direction of the water purifier 100, based on the fact that the cover plate 2 needs to move relative to the body housing 1 along the length direction of the water purifier 100 during its disassembly and assembly movement. If the cover plate 2 needs to move relative to the body housing 1 along the width direction of the water purifier 100 during its disassembly and assembly movement, then the second limiting part 11 acts as a blocking and limiting element in the width direction of the water purifier 100. Alternatively, if the cover plate 2 needs to move relative to the body housing 1 along the height direction of the water purifier 100 during its disassembly and assembly movement, then the second limiting part 11 acts as a blocking and limiting element in the height direction of the water purifier 100.

[0061] See Figures 1 to 3 As shown, in another embodiment of this application, the first sliding limiting part 31 is one of a sliding groove and a slider, and the second sliding limiting part 32 is the other of a sliding groove and a slider, with the sliding groove and the slider slidingly engaged. In other words, when the first sliding limiting part 31 is selected as a sliding groove, the second sliding limiting part 32 is selected as the corresponding slider, or when the first sliding limiting part 31 is selected as a slider, the second sliding limiting part 32 is selected as the corresponding sliding groove.

[0062] For example, in the upper region of the housing 1, sliding grooves (i.e., first sliding limiting parts 31) are respectively provided on the left and right sides of the housing 1, and the sliding grooves extend along the length direction of the housing 1 (the length direction of the housing 1 is the same as the length direction of the water purifier 100). The opening of the sliding groove on the left side is open to the left, and the opening of the sliding groove on the right side is open to the right. See also... Figure 3As shown, a corresponding slider (i.e., the second sliding limit part 32) is provided on the inner side of the edging 21 of the cover plate 2. The slider is elongated and extends along the length direction of the cover plate 2 (the length direction of the cover plate 2 is the same as the length direction of the water purifier 100). Based on this, when the cover plate 2 is assembled into the housing 1 (i.e., the slider is located in the corresponding groove), the cover plate 2 can slide relative to the housing 1 along the length direction of the water purifier 100. Therefore, in this embodiment, the disassembly and assembly trajectory is linear, that is, the disassembly and assembly trajectory is parallel to the length direction of the water purifier 100.

[0063] In some of the above embodiments, the water purifier 100 is provided with a sliding engagement mechanism. Under the cooperative action of the first sliding limiting part 31 and the second sliding limiting part 32 in the sliding engagement mechanism, the sliding engagement mechanism can limit the cover plate 2 and the body housing 1 in the height direction of the water purifier 100. Therefore, in the relevant embodiments, by configuring the sliding engagement mechanism to limit the relative position of the cover plate 2 and the body housing 1 in the length direction of the water purifier 100, the effect of locking the cover plate 2 to the body housing 1 can be achieved.

[0064] However, this application is not limited to this. In other embodiments of this application, there are also embodiments without a sliding fit mechanism. In other words, in these embodiments, a sliding fit mechanism is not used to achieve a limiting fit between the cover plate 2 and the body housing 1 in at least one direction of the water purifier 100.

[0065] For example, the water purifier 100 includes at least two locking mechanisms 4, wherein at least one locking mechanism 4 is configured to selectively restrict the movement of the cover plate 2 relative to the body housing 1 in the height direction of the water purifier 100, and at least another locking mechanism 4 is configured to selectively restrict the movement of the cover plate 2 relative to the body housing 1 in the length direction of the water purifier 100. Thus, in this embodiment, the water purifier 100 can achieve the purpose of limiting the fit between the cover plate 2 and the body housing 1 in the height direction of the water purifier 100 without employing a sliding fit mechanism. Multiple locking mechanisms 4 can be provided, allowing these locking mechanisms 4 to perform limiting functions in different directions.

[0066] In another embodiment, the multiple locking mechanisms 4 provided in the water purifier 100 may all be configured to limit movement in the same direction. For example, see [reference needed]. Figures 1 to 3As shown, in this embodiment, taking the cover plate 2 being installed and removed from the housing 1 along the height direction of the water purifier 100 as an example, the installation and removal trajectory is linear and parallel to the height direction of the water purifier 100. Based on this, the locking mechanisms 4 installed on the water purifier 100 are all configured to limit movement along the height direction of the water purifier 100. This achieves the effect of locking the cover plate 2 to the housing 1 via the locking mechanisms 4.

[0067] In summary, according to the water purifier 100 of this application, the locking mechanism 4 has a locking member 41 that can move between a locked position and an unlocked position. When the locking member 41 is in the locked position, it can prevent the cover plate 2 from moving relative to the body housing 1, so that the cover plate 2 is locked and fixed to the body housing 1 to cover the receiving space 10. When the locking member 41 is in the unlocked position, it can allow the cover plate 2 to move relative to the body housing 1, so that the cover plate 2 is removed from the body housing 1 to open the receiving space 10.

[0068] It should be noted that in some of the above embodiments, Figure 4 The locking element 41 is shown in the locked position. Figure 5 The locking element 41 is shown in the unlocked position. It is worth noting that... Figure 4 and Figure 5 The locking and unlocking positions indicated herein represent only the locking and unlocking positions in one embodiment of this application. Regarding the specific positions of the locking and unlocking positions, it is sufficient that when the locking member 41 is in the locking position, it prevents the cover plate 2 from moving relative to the housing 1 along the disassembly / removal trajectory, and when the locking member 41 is in the unlocking position, it allows the cover plate 2 to move relative to the housing 1 along the disassembly / removal trajectory.

[0069] See Figure 4 and Figure 5 As shown, in some embodiments of this application, the locking mechanism 4 further includes a first magnetic element 42, which is assembled on the locking element 41. The first magnetic element 42 is used to cooperate with the second magnetic element to generate a magnetic force. Under the action of the magnetic force, the locking element 41 moves to the unlocked position along the locking movement trajectory S1, thereby allowing the cover plate 2 to move relative to the body housing 1 along the disassembly and assembly movement trajectory, so as to achieve the effect of opening the accommodating space 10 by the cover plate 2.

[0070] For example, in combination Figure 4 and Figure 5 As shown, for example, the first magnetic element 42 is configured as the N pole, and the second magnetic element is configured as the corresponding S pole. Utilizing the principle of attraction between opposite poles of magnets, the first magnetic element 42 and the second magnetic element cooperate to generate a magnetic attraction force. Under the action of this magnetic attraction force, the locking element 41 is driven to move along the locking element movement trajectory S1 to the unlocked position. More specifically, in conjunction with... Figure 4 and Figure 5As shown, when the operator needs to unlock the cover plate 2, the operator places the second magnetic component on the upper surface of the cover plate 2. Along the height direction of the water purifier 100, the orthographic projection of the first magnetic component 42 along the height direction of the water purifier 100 and the orthographic projection of the second magnetic component along the height direction of the water purifier 100 at least partially overlap, so that the first magnetic component 42 and the second magnetic component generate a magnetic attraction force. Under the action of the magnetic attraction force, the locking component 41 moves along the locking component movement trajectory S1 to the unlock position, causing the first limiting part 411 and the second limiting part 11 to be released from their limiting positions. Then, the operator can drive the cover plate 2 to move relative to the body housing 1, causing the cover plate 2 to detach from the body housing 1, thus achieving the effect of opening the receiving space 10.

[0071] It is worth noting that in some embodiments of this application, the locking member 41 is equipped with a first magnetic member 42, and the magnetic force generated by the first magnetic member 42 and the second magnetic member drives the locking member 41 to move along the locking member movement trajectory S1 to the unlocked position. This unlocking method eliminates the need for a keyhole in the water purifier 100, making the appearance of the water purifier 100 neat and aesthetically pleasing, while also concealing the lock body. This increases the difficulty for personnel unfamiliar with the specific opening method to remove the cover 2 from the body housing 1 to open the receiving space 10, thereby more effectively preventing temporary hotel guests from opening the receiving space 10 and causing filter contamination. It should also be noted that in the above embodiments, only the first magnetic member 42 and the second magnetic member cooperate to generate magnetic attraction to achieve the effect of driving the locking member 41 to move. In other embodiments, the first magnetic member 42 and the second magnetic member can also cooperate to generate magnetic repulsion to achieve the effect of driving the locking member 41 to move.

[0072] It should be further explained that in some of the above embodiments, the example given is that the locking member 41 is driven to move along the locking member movement trajectory S1 to the unlocked position by the cooperation of the first magnetic element 42 and the second magnetic element to generate a magnetic force. However, this application is not limited to this. In other embodiments of this application, the locking mechanism 4 also includes a driver (e.g., a servo motor), which is used to drive the locking member 41 to move along the locking member movement trajectory S1 to the unlocked position. Specifically, the water purifier 100 is also equipped with a remote control, which is communicatively connected to the driver, so that the operator can control the driver to drive the locking member 41 to move along the locking member movement trajectory S1 to the unlocked position. Furthermore, the scheme of using a driver to drive the locking member 41 to move along the locking member movement trajectory S1 to the unlocked position also eliminates the need for a keyhole in the water purifier 100, making the appearance of the water purifier 100 neat and beautiful, while also concealing the lock body. This increases the difficulty for people who do not know the specific opening method (such as temporary hotel guests) to remove the cover 2 from the body housing 1 to open the receiving space 10. Therefore, the water purifier 100 according to this application more effectively prevents the problem of filter contamination caused by temporary hotel guests opening the accommodation space 10.

[0073] Combination Figures 3 to 5 As shown, in some embodiments of this application, the first limiting part 411 is provided with an abutment surface 411a and a guide slope 411b facing opposite directions. When the cover plate 2 and the housing 1 are in a snap-fit ​​state and the locking member 41 is in the locked position, the first limiting part 411 of the locking member 41 is located in front of the second limiting part 11 along the length direction of the water purifier 100. If the operator applies a force to the cover plate 2 to move the cover plate 2 from front to back along the disassembly and assembly movement trajectory, the abutment surface 411a is adapted to abut against the second limiting part 11 to limit the movement, thereby restricting the cover plate 2 from further moving from front to back along the disassembly and assembly movement trajectory.

[0074] Furthermore, during the process of the operator changing the cover plate 2 from a released state to a fastened state relative to the body housing 1, the locking member 41 can be in the locked position under the action of force (e.g., the gravity of the locking member 41 and / or the external force acting on the locking member 41), and at this time, the first limiting part 411 of the locking member 41 is located behind the second limiting part 11 along the length direction of the water purifier 100. If the operator applies a force to the cover plate 2 to move the cover plate 2 from back to front along the disassembly and assembly movement trajectory, the guide slope 411b is adapted to contact the second limiting part 11. During the contact between the guide slope 411b and the second limiting part 11, the second limiting part 11 drives the locking member 41 to move from the locked position to the unlocked position along the locking member movement trajectory S1, thereby causing the first limiting part 411 to avoid the second limiting part 11, so that the cover plate 2 can be further moved from back to front along the disassembly and assembly movement trajectory, so that the cover plate 2 and the body housing 1 are in the fastened state.

[0075] See Figure 4 and Figure 5 As shown, in some embodiments of this application, the locking mechanism 4 may further include an elastic element 43. Along the movement trajectory S1 of the locking element, the elastic element 43 is disposed between the cover plate 2 and the locking element 41. The elastic element 43 is used to drive the locking element 41 to reset to the locked position. This ensures that the locking element 41 is in the locked position, effectively guaranteeing that the locking mechanism 4 can be used to lock the cover plate 2 to the housing 1. See also... Figure 4 and Figure 5 As shown, in one embodiment of this application, the elastic element 43 is described as a helical spring, but this application is not limited to this. The elastic element 43 can be a component with elastic properties such as elastic rubber.

[0076] See Figures 3 to 5 As shown, in some embodiments of this application, the locking mechanism 4 further includes a lock housing 44, within which a lock cylinder space 440 is provided, and the locking member 41 is rotatably assembled within the lock cylinder space 440. A clearance hole 442a is provided on the side of the lock housing 44 facing the body housing 1. The clearance hole 442a is used to avoid the first limiting portion 411 of the locking member 41, allowing the first limiting portion 411 to extend out of the lock housing 44 to engage with the second limiting portion 11 of the body housing 1.

[0077] For example, see Figure 4 and Figure 5 As shown, in one embodiment of this application, the lock housing 44 includes a first housing 441 and a second housing 442 that are fastened together in opposite directions. It can also be understood that the first housing 441 and the second housing 442 are fastened together to form the lock housing 44, and the first housing 441 and the second housing 442 are fastened together to jointly define the lock cylinder space 440.

[0078] See Figure 3 As shown, both the peripheral walls of the first housing 441 and the second housing 442 have notches. When the first housing 441 and the second housing 442 are fastened together to form a lock housing 44, the notches in the first housing 441 and the second housing 442 together define a pivot hole 443. Therefore, two axisymmetric pivot holes 443 are defined in the lock housing 44. See also... Figure 4 As shown, along the extending direction of the locking member 41, a pivot shaft 413 is provided at one end of the locking member 41 away from the first limiting part 411. The two ends of the pivot shaft 413 are respectively inserted into two axisymmetric pivot holes 443, so that the locking member 41 can be rotatably assembled to the lock housing 44, so that the locking member 41 moves along the arc-shaped lock movement trajectory S1.

[0079] See Figure 4 and Figure 5As shown, the second housing 442 is also provided with a clearance hole 442a. That is, along the height direction of the water purifier 100, the lock housing 44 is provided with a clearance hole 442a on the side facing the body housing 1. The clearance hole 442a is used to allow the first limiting part 411 provided on the locking member 41 to extend out of the lock housing 44, so that when the locking member 41 is in the locked position, the first limiting part 411 is suitable to abut against and limit the second limiting part 11.

[0080] It should be noted that, see reference Figure 4 and Figure 5 As shown, when the locking member 41 is in the locked position, it abuts against the second housing 442 in the height direction of the water purifier 100. This provides strong support for the locking member 41 from the second housing 442 in the height direction of the water purifier 100, effectively preventing excessive downward displacement of the locking member 41. Furthermore, when the locking member 41 is in the locked position, the distance between the first magnetic member 42 and the upper surface of the cover plate 2 can be precisely limited in the height direction of the water purifier 100. This ensures that the second magnetic member and the first magnetic member 42 placed on the upper surface of the cover plate 2 generate a magnetic attraction force sufficient to drive the locking member 41 to move along the locking member movement trajectory S1, allowing the locking member 41 to move from the locked position to the unlocked position.

[0081] Combination Figure 3 and Figure 4 As shown, the first housing 441 and the cover plate 2 are integrally formed, that is, the first housing 441 is integrated into the cover plate 2, and then the second housing 442 is fastened to the first housing 441, thereby achieving the effect of assembling the lock housing 44 onto the cover plate 2, that is, defining the relative position of the lock housing 44 and the cover plate 2.

[0082] See Figure 4 and Figure 5 As shown, the lock housing 44 is also provided with a limiting post 444, which is integrally formed with the cover plate 2 and located within the lock cylinder space 440. During the process of the locking member 41 moving from the locked position to the unlocked position along the lock member movement trajectory S1, the locking member 41 is adapted to abut against the limiting post 444 along the height direction of the water purifier 100. This can prevent the first limiting part 411 from completely moving out of the clearance hole 442a, and ensure that the first limiting part 411 can extend out of the lock housing 44 through the clearance hole 442a during the reciprocating movement of the locking member 41 along the lock member movement trajectory S1.

[0083] See Figure 4 and Figure 5As shown, the locking member 41 is also provided with an assembly groove 412, and the limiting post 444 is adapted to extend into the assembly groove 412, so that the limiting post 444 can not only play the role of abutting and limiting the locking member 41, but also the limiting post 444 and the assembly groove 412 play the role of guiding and cooperating, thereby causing the locking member 41 to move along the locking member movement trajectory S1.

[0084] In another embodiment of this application, taking the elastic element 43 as a helical spring as an example, the elastic element 43 is sleeved on the limiting post 444 and the elastic element 43 is installed in the assembly groove 412. The assembly groove 412 also plays a limiting role for the elastic element 43, thereby preventing the elastic element 43 from separating from the locking element 41 and ensuring that the locking element 41 can be effectively reset to the locking position.

[0085] Combination Figure 1 and Figure 3 As shown, in some embodiments of this application, the housing 1 includes a main body 1a and a head housing 1b. The head housing 1b is assembled to the main body 1a, and the cover plate 2 is used to be movably assembled to the main body 1a along the disassembly and assembly trajectory. Along the height direction of the water purifier 100, the upper end face of the head housing 1b is higher than the upper end face of the main body 1a. Therefore, in order to enable the cover plate 2 to be assembled to the main body 1a, an avoidance notch 22 is provided in the cover plate 2 so that during the process of the cover plate 2 moving along the disassembly and assembly trajectory to be assembled to the main body 1a, the avoidance notch 22 is used to avoid the head housing 1b, thereby enabling the cover plate 2 to completely cover the opening of the accommodating space 10.

[0086] See Figure 6 As shown, in some embodiments of this application, the water purifier 100 further includes a water circuit module 5, which is arranged within the accommodating space 10. The water circuit module 5 includes a first water inlet 51, a second water inlet 52, a filter 53, and a storage and supply water section 54. One end of the filter 53 is connected in parallel with the first water inlet 51 and the second water inlet 52, and the other end of the filter 53 is connected to the storage and supply water section 54. The first water inlet 51 is used to connect to the raw water tank 511, and the second water inlet 52 is used to connect to the raw water source.

[0087] The first water inlet 51 is provided with a first valve body 513, which is configured to selectively connect the first water inlet 51 and the filter section 53. In other words, by controlling the opening and closing of the first valve body 513, raw water stored in the raw water tank 511 can selectively flow into the filter section 53 through the first water inlet 51. Specifically, when the first valve body 513 is open, raw water stored in the raw water tank 511 can flow into the filter section 53 through the first water inlet 51. When the first valve body 513 is closed, raw water stored in the raw water tank 511 cannot flow into the filter section 53 through the first water inlet 51.

[0088] The second water inlet 52 is equipped with a second valve body 523, which is configured to selectively connect the second water inlet 52 and the filter section 53. In other words, by controlling the opening and closing of the second valve body 523, raw water supplied by the raw water source can selectively flow into the filter section 53 through the second water inlet 52. Specifically, when the second valve body 523 is open, raw water supplied by the raw water source can flow into the filter section 53 through the second water inlet 52. When the second valve body 523 is closed, raw water supplied by the raw water source cannot flow into the filter section 53 through the second water inlet 52.

[0089] Thus, the first water inlet 51 and the second water inlet 52 selectively pass raw water into the filter section 53. After being filtered by the filter section 53, the raw water forms clean water that flows to the storage and supply section 54.

[0090] It should be understood that raw water is water that has not been filtered by the filter unit 53, purified water is water that has been filtered by the filter unit 53, the raw water tank 511 can be an external tank placed in the water purifier 100, or the raw water tank 511 can be a tank built into the containing space 10, and the raw water source can be understood as a tap water faucet.

[0091] For example, see Figure 6 As shown, in one embodiment of this application, the water storage and supply unit 54 includes a purified water tank 541, a heating element 543, and a water vapor separator outlet 6. The heating element 543 is connected between the purified water outlet 541b of the purified water tank 541 and the terminal inlet 60a of the water vapor separator outlet 6. The purified water stored in the purified water tank 541 can be heated into hot water by the heating element 543, and then the hot water flows into the water vapor separator outlet 6. Since the hot water contains water vapor, the water vapor can be discharged from the water vapor separator outlet 6 through the gas outlet 60b, and then discharged into the purified water tank 541 through the gas inlet 541c. The purified water tank 541 is also provided with a wastewater outlet, which is used to discharge the purified water stored in the purified water tank 541. In this way, the purified water stored in the purified water tank 541 for a long time can be directly discharged from the water purifier 100 without the heating element 543 and the water vapor separator outlet 6. It can not only remove the purified water that has been stored in the purified water tank 541 for a long time, but also prevent the purified water stored in the purified water tank 541 for a long time from causing pollution to the heating element 543 and the water vapor separator.

[0092] For more details, please refer to Figure 6As shown, in one embodiment of this application, the first water inlet 51 may be provided with a raw water tank 511, a first water pump 512 and a first valve body 513. The raw water tank 511 is also provided with a first liquid level sensor 511a, which is used to monitor the liquid level in the raw water tank 511. The first water pump 512 can be a water pump powered by a 12-volt power supply or a 24-volt power supply.

[0093] The second water inlet section 52 may be equipped with an inlet tee 521, a pressure reducing valve 522, and a second valve body 523. One port of the inlet tee 521 is used to connect to the raw water source, allowing the raw water source to flow into the second water inlet section 52. The pressure reducing valve 522 is used to reduce the pressure inside the second water inlet section 52 to prevent excessive pressure. The second valve body 523 can be a normally closed solenoid valve. The normally closed solenoid valve is in a closed state when not energized, meaning that liquid cannot pass through the normally closed solenoid valve.

[0094] The first water inlet 51 and the second water inlet 52 are connected in parallel to the filter section 53 via a manifold tee 531. The filter section 53 is provided with at least one set of filter cartridges 532, each set of filter cartridges 532 including at least two filter cartridges 532a connected in series. In this embodiment, the filter section 53 is provided with one set of filter cartridges 532, wherein the filter cartridges 532 have two filter cartridges 532a connected in series. The upstream filter cartridge 532a can be a polypropylene activated carbon resin composite filter cartridge, and the downstream filter cartridge 532a can be an activated carbon ultrafiltration composite filter cartridge. The filter section 53 is also provided with a third valve body 533, which is located at the end of the filter section 53, so as to selectively connect the filter section 53 to the storage water supply section 54 by controlling the opening and closing of the third valve body 533. The third valve body 533 can be a normally open solenoid valve.

[0095] The water storage and supply unit 54 includes a purified water tank 541, a second water pump 542, a heating element 543, and a water vapor separator outlet 6. The purified water inlet 541a of the purified water tank 541 is connected to a third valve body 533, allowing purified water obtained after filtration by the filtration unit 53 to flow into the purified water tank 541 for storage. The purified water tank 541 is also equipped with a second liquid level sensor 541d, which is used to monitor the liquid level in the purified water tank 541. When the second liquid level sensor 541d sends the monitored liquid level information to the controller of the purified water tank 541, the controller analyzes and judges the corresponding liquid level information and determines that the liquid level in the purified water tank 541 has reached the maximum liquid level. The controller can then send a control signal to the third valve body 533 (in the case where the third valve body 533 is a normally open solenoid valve) in the filter section 53 to control the third valve body 533 to adjust to the closed state, thereby preventing the liquid level in the purified water tank 541 from being too high.

[0096] The second water pump 542 is connected between the purified water tank 541 and the heating element 543. The second water pump 542 pumps the purified water stored in the purified water tank 541 to the heating element 543, so that the purified water is heated by the heating element 543, enabling the water purifier 100 according to this application to have the function of dispensing hot water. The second water pump 542 can be a water pump powered by a 12-volt or 24-volt power supply. It is worth noting that the heating method of the heating element 543 is optional. For example, when the user needs hot water, the heating element 543 activates its heating function to heat the purified water in the heating element 543 to a preset temperature. If the user needs room temperature water, the heating element 543 does not activate its heating function. This can be understood as the heating element 543 acting as a conduit, allowing room temperature purified water to flow through the heating element 543 into the water vapor separator outlet 6. The user can then access purified water at the water vapor separator outlet 6.

[0097] In one embodiment of this application, see reference Figure 1 As shown, the water circuit module 5 is provided with an inlet water port 50a and a wastewater outlet 50b. The water purifier 100 may also be provided with two elbow-connector pipes 7, which are respectively assembled and connected to the inlet water port 50a and the wastewater outlet 50b, so that the elbow-connector pipes 7 can be indirectly assembled into the housing 1. It should be understood that the water circuit module 5 is assembled inside the housing 1. For the elbow-connector pipe 7 connected to the inlet water port 50a, the port of the elbow-connector pipe 7 furthest from the inlet water port 50a can be connected to a water pipe used to supply raw water. For the elbow-connector pipe 7 connected to the wastewater outlet 50b, the port of the elbow-connector pipe 7 furthest from the wastewater outlet 50b can be connected to a wastewater pipe, which guides the wastewater discharged from the wastewater outlet 50b into a sewage pipe.

[0098] Because of the use of the elbow adapter 7, compared to directly connecting the inlet port 50a and / or the wastewater outlet 50b to a flexible water pipe (i.e., a flexible pipe) is used, the bending problem caused by the angle between the flexible water pipe and the water purifier 100 can be avoided, thus preventing the adverse effects of the flexible water pipe bending. For rigid water pipes (i.e., non-flexible pipes), when the angle between the rigid water pipe and the water purifier 100 is not compatible, the elbow adapter 7 is used to facilitate the connection of the rigid water pipe to the inlet port 50a and the wastewater outlet 50b.

[0099] See Figure 6 and Figure 7As shown in some embodiments of this application, the water vapor separator 6 is provided with a flow space 60, which is connected to both the terminal water inlet 60a and the gas outlet 60b. When the purified water flowing into the flow space 60 from the terminal water inlet 60a is hot water, the water vapor carried by the hot water can be discharged from the flow space 60 through the gas outlet 60b and flow into the purified water tank 541 through the gas inlet 541c connected to the gas outlet 60b. This enables the water vapor separator 6 to have a water vapor separation function, which can effectively prevent the outflowing water from failing to form a water column and from spraying steam, thereby preventing the hot water from scalding the user. It's important to understand that: "When water is heated, it produces steam. If this steam flows out along with the hot water, it can easily cause scalding when the user fills the container. A steam separator separates the steam from the hot water, ensuring only hot water flows out of the outlet, reducing the risk of the user coming into contact with hot steam. For example, in a water dispenser without a steam separator, a large amount of hot steam may spray out along with the hot water when it's dispensed; if the user accidentally touches the steam, they could be scalded. With a steam separator, this situation can be avoided."

[0100] Furthermore, combined Figure 7 and Figure 8 As shown, the water vapor separator 6 also has a water vapor outlet 60c, which is the outlet of the water supply unit 54. That is, the purified water flowing into the flow space 60 is discharged through the water vapor outlet 60c. It is worth noting that the water vapor outlet 60c includes at least two unit outlets 62. These unit outlets 62 have different height differences within the flow space 60, allowing the water vapor in the flow space 60 to be configured to flow out through the unit outlets 62 where purified water has not flowed, thus achieving water vapor separation. It is also worth noting that the water vapor separator 6 according to this application has at least two stages of water vapor separation, where the first stage of water vapor separation is achieved by the gas outlet 60b, and the second stage of water vapor separation is achieved by the water vapor outlet 60c.

[0101] Combination Figure 7 and Figure 8 As shown, a plurality of flow dividers 61 are provided within the flow space 60, which are used to form a plurality of unit outlets 62 with different height differences within the flow space 60. More specifically, in conjunction with Figure 7 and Figure 8 As shown, the flow space 60 is provided with two first diversion baffles 61a and one second diversion baffle 61b, wherein the two first diversion baffles 61a are symmetrically arranged and spaced apart, and the second diversion baffle 61b is connected between the two first diversion baffles 61a. The plurality of unit outlets 62 formed in the flow space 60 include one first-order unit outlet 62a, one second-order unit outlet 62b and two third-order unit outlets 62c.

[0102] It is worth noting that along the height direction of the water vapor separation outlet 6 (i.e. Figure 7 and Figure 8 As shown in the Z direction, the upper surface of the second diversion baffle 61b is higher than the first-order unit outlet 62a, and the upper surface of the first diversion baffle 61a is higher than the upper surface of the second diversion baffle 61b. This can also be understood as follows: when the liquid level in the first-order unit outlet 62a is higher than the height of the second diversion baffle 61b, the purified water in the first-order unit outlet 62a can overflow from the first-order unit outlet 62a into the second-order unit outlet 62b; when the liquid level in the second-order unit outlet 62b is higher than the height of the first diversion baffle 61a, the purified water in the second-order unit outlet 62b can overflow from the second-order unit outlet 62b into the third-order unit outlet 62c. Furthermore, when the liquid level in the first-stage unit outlet 62a is lower than the height of the second diversion baffle 61b, the purified water can only be discharged through the first-stage unit outlet 62a. However, due to the low density of the gas, water vapor can be discharged through the second-stage unit outlet 62b and the third-stage unit outlet 62c. Similarly, when the influent in the first-stage unit outlet 62a overflows into the second-stage unit outlet 62b, and the liquid level in the second-stage unit outlet 62b is lower than the height of the second diversion baffle 61b, the purified water can only be discharged through the first-stage unit outlet 62a and the second-stage unit outlet 62b. At this time, water vapor can be discharged through the third-stage unit outlet 62c.

[0103] In summary, the water vapor separation outlet 6 according to this application not only has the function of two-stage water vapor separation in general, but also can be further subdivided into multiple sub-stage water vapor separation in the second stage. As described in the above embodiments, two first diversion baffles 61a and one second diversion baffle 61b are provided in the flow space 60 to form a first-order unit outlet 62a, a second-order unit outlet 62b, and two third-order unit outlets 62c within the flow space 60. The first sub-stage water vapor separation occurs when purified water is discharged only through the first-order unit outlet 62a, and water vapor is discharged through the second-order unit outlet 62b and the third-order unit outlet 62c; the second sub-stage water vapor separation occurs when purified water is discharged through the first-order unit outlet 62a and the second-order unit outlet 62b, and water vapor is discharged through the third-order unit outlet 62c.

[0104] It is also worth noting that by providing several flow-diverting baffles 61 within the flow space 60, these baffles create several unit outlets 62 with different height differences within the flow space 60. The flow-diverting baffles 61 slow down the flow velocity of the liquid. When the flow velocity of the purified water flowing into the flow space 60 from the terminal inlet 60a is too high, the flow-diverting baffles 61 slow down the flow velocity, making it easier for the water flowing out of the steam outlet 60c to form a water column, reducing splashing, and thus reducing the risk of scalding the user with high-temperature purified water, thereby improving the user experience.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
