[0036] The following is in conjunction with the appendix Figure 1-5 The embodiments of this application will be described in further detail.

[0037] Figure 1 An isometric view of the water purifier according to one embodiment of this application is shown; Figure 2 An exploded view of a water purifier according to one embodiment of the application is shown; Figure 3 A schematic diagram of the slider 23 and button 22 in one embodiment of this application is shown. (See attached diagram.) Figures 1 to 3 This application provides a water purifier comprising: a main body 1 and a door opening structure 2, the main body 1 and the door opening structure 2 being rotatably connected. The main body 1 includes a housing 11 and a filter element 12 embedded in the housing 11. When the door opening structure 2 is engaged with the main body 1, it provides good dust and water protection for the filter element 12; when the door opening structure 2 is separated from the main body 1, the end of the filter element 12 is exposed, facilitating the installation and removal of the filter element 12.

[0038] In one embodiment of this application, the door opening structure 2 includes: a cover 21, disposed at one end of the filter element 12 in the water purifier; a button 22, movably connected to the cover 21, the first side of the button 22 having a mating part 222; a slider 23, the first surface of the slider 23 having a toggle member 231, the toggle member 231 being inserted into the cover 21, used to control the button 22 to switch between a locked state and an unlocked state according to the user's operation; the second surface of the slider 23 having a locking part 232, the slider 23... The first surface of the button 22 is adjacent to the second surface of the sliding button 23; wherein, when the button 22 is in the locked state, the sliding button 23 moves to the first position, and the locking part 232 and the mating part 222 are misaligned to restrict the movement of the button 22; when the button 22 is in the unlocked state, the sliding button 23 moves to the second position, and the locking part 232 and the mating part 222 are opposite to each other, so that the button 22 can move along the first direction to control the cover 21 to switch between the open state and the closed state.

[0039] The button 22 can move along a first direction and the opposite direction under the action of external force, controlling the cover 21 to switch between an open state and a closed state. The cover 21 is set at one end of the filter element 12. The first side of the cover 21 is hinged to the main body 1 of the water purifier. When switching to the open state, the second side of the cover 21 moves away from the main body 1 of the water purifier with the first side as the axis. When switching to the closed state, the second side of the cover 21 moves towards the main body 1 of the water purifier with the first side as the axis, until it is engaged with the main body 1 of the water purifier.

[0040] Figure 4 A cross-sectional view of the button 22 in one embodiment of this application is shown. For example, as shown... Figure 4 As shown, the first side of button 22 is provided with a first hook 221, and the main body 1 of the water purifier is provided with a second hook 13. When the cover 21 is in the closed state, the first hook 221 and the second hook 13 are engaged. Using external force, button 22 is moved along the first direction, causing the first hook 221 on the first side of button 22 to separate from the second hook 13 on the main body 1, and the cover 21 switches from the closed state to the open state. When it is necessary to switch to the closed state, button 22 moves in the opposite direction of the first direction, causing the first hook 221 on the first side of button 22 to return to the engaged state with the second hook 13 on the main body 1, and the cover 21 switches from the open state to the closed state.

[0041] exist Figure 3In the view shown, the front of the slider 23 is the first side of the slider 23. The toggle member 231 protrudes from the surface of the first side of the slider 23 and passes through the cover 21, so that the user can operate the toggle member 231 from outside the water purifier and thus move the position of the slider 23. The top surface of the slider 23 is the second side of the slider 23, which is provided with a locking part 232 and faces the bottom edge of the button 22. The bottom edge of the button 22 is the first side of the button 22.

[0042] Optionally, the locking part 232 can be a protrusion, and correspondingly, the mating part 222 can be a groove. Figure 4 From the perspective of [unclear context], the slider 23 is in the first position, and the button 22 is in the locked state. The locking part 232 abuts against the lower edge of the first side of the button 22, preventing the button 22 from moving relative to the cover 21. Therefore, the button 22 cannot be pressed by external force, and thus the button 22 cannot be used to control the cover 21 to switch between the open and closed states. Operating the toggle member 231 allows the slider 23 to move along the first direction until it reaches the second position. In the second position, the locking part 232 is located directly below the mating part 222, and the button 22 is in the unlocked state. By pressing the button 22 by external force, the button 22 can move along the second direction, thus controlling the cover 21 to switch between the open and closed states. The first direction is [unclear context]. Figure 3 The direction indicated by the arrow marked "X" in the middle; the second direction is... Figure 3 The direction indicated by the arrow marked "Y".

[0043] Optionally, the locking part 232 can be a groove, and the corresponding mating part 222 can be a protrusion. When the button 22 is in the locked state, the slider 23 moves to the first position, and the mating part 222 abuts against the upper edge of the slider 23 to restrict the movement of the button 22. When the button 22 is in the unlocked state, the slider 23 moves to the second position, and the locking part is opposite to the mating part, so that the button can move along the first direction to control the cover to switch between the open state and the closed state.

[0044] In this embodiment, by moving the slider 23 to the first position or the second position, the control button 22 switches between the locked and unlocked states. The user can control the cover 21 to open or close by simply sliding and pressing. The operation is intuitive and simple, the structure occupies little space, and it can effectively prevent the cover 21 from opening and exposing the filter element 12 due to accidental contact during the operation of the water purifier, thereby improving the safety and reliability of the water purifier.

[0045] Figure 5 A schematic diagram of the inner cover 212 in one embodiment of this application is shown. (See also...) Figures 1 to 5In one embodiment of this application, the cover 21 of the door opening structure 2 includes: an outer cover 211; an inner cover 212, the first surface of the inner cover 212 facing the outer cover 211 and connected to the outer cover 211, and the second surface of the inner cover 212 facing the main body 1 of the water purifier; a receiving cavity is formed between the inner cover 212 and the outer cover 211 for accommodating the button 22 and the slider 23.

[0046] The inner cover 212 and the outer cover 211 can be engaged by snaps or fixed by screws. When the cover 21 is in the closed state, the outer cover 211 serves to seal the filter element 12 and prevent dust and pollution. The button 22 and the slider 23 are both installed between the inner cover 212 and the outer cover 211.

[0047] exist Figure 5 In the view shown, the inner cover 212 has an arc-shaped opening at its first end, which is used to accommodate the end of the filter element 12. The edge of the opening has reinforcing ribs 2124 to increase overall rigidity, prevent deformation during long-term use, and improve durability. The sliding button 23 is located in the area at the top of the reinforcing ribs 2124.

[0048] The inner cover 212 is also provided with a pin hole 2125 at the first end, which is used to cooperate with the pin to hinge the inner cover 212 to the main body 1 of the water purifier, thereby connecting the entire door opening structure 2 to the main body 1 of the water purifier.

[0049] In one possible implementation, a limiting member 2121 is provided on the first surface of the inner cover 212 to limit the movement path of the slider 23.

[0050] Optionally, the limiting member 2121 can be a limiting rib distributed along the moving direction of the slider 23, and the limiting rib includes a first limiting rib and a second limiting rib. Figure 5 From the perspective shown, the first limiting rib is Figure 5 The left-side limiting reinforcement; the second limiting reinforcement is... Figure 5 The right-side limiting rib. The third side of the slide button 23 has a groove that engages with the limiting rib. When the slide button 23 is in the first position, the groove engages with the first limiting rib; when the slide button 23 moves from the first position to the second position, the groove engages with the second limiting rib.

[0051] Optionally, the limiting member 2121 can be a limiting groove provided at both ends or in the middle of the sliding path of the slider 23 to limit the position of the slider 23. The third surface of the slider 23 has a positioning part, which engages with the limiting groove when the slider 23 slides to the first position or the second position.

[0052] Optionally, the limiting member 2121 can be a sliding channel, and the third side of the sliding button 23 is embedded in the sliding channel, moving to the first position or the second position in the sliding channel.

[0053] In this embodiment, the limiting member 2121 provided in the inner cover 212 ensures that the slide button 23 can only move along a specific trajectory, which can prevent the slide button 23 from moving due to vibration or accidental contact, and ensure that the slide button 23 can accurately move to the preset first position or second position, thereby improving the reliability of the locking function.

[0054] See Figures 1 to 3 In one embodiment of this application, the outer cover 211 of the door opening structure 2 is provided with a guide groove 2114; the toggle member 231 is installed in the guide groove 2114, so that the slider 23 can move relative to the button 22 along the extension direction of the guide groove 2114.

[0055] Among them, the toggle 231 on the first surface of the slider 23 is connected to the outside through the guide groove 2114 on the outer cover 211. In this way, the user can operate the toggle 231 from the outside of the water purifier to push the slider 23 along the extension direction of the guide groove 2114, thereby controlling the button 22 to switch between the locked and unlocked states.

[0056] The outer cover 211 has an L-shaped rib 2111 facing the inner cover 212. The rib 2111 includes a first rib segment 2112 and a second rib segment 2113 that are perpendicular to each other. The first rib segment 2112 is located close to the button 22, and there is a gap between the second rib segment 2113 and the first side of the button 22.

[0057] The second rib segments 2113 of the oppositely arranged ribs 2111 are respectively located on both sides of the slide button 23.

[0058] The inner cover 212 has a mounting area 2126 at its second end. The ribs 2111 of the outer cover 211 cooperate with the mounting area to form a button mounting area, allowing the button 22 mounted in the mounting area to move relative to the cover 21. When the button 22 is installed in the cover 21, the surface of the second side of the button 22 is slightly higher than the surface of the second end of the inner cover 212, facilitating user finger pressing. Figure 3 In the view shown, the top edge of the button is the second side of the button.

[0059] In one possible implementation, a mounting hole is provided on the second rib segment 2113; a guide post 223 is also provided on the first side of the button 22, and the first end of the guide post 223 passes through the mounting hole, so that the button 22 can move along the extension direction of the guide post 223.

[0060] exist Figure 3 From this perspective, the extension direction of the guide post 223 is the second direction indicated by the arrow marked "Y".

[0061] Optionally, the guide posts 223 are arranged in pairs. Two mounting slots 224 are provided on the first side of the button 22, symmetrically arranged on both sides of the mating part 222. The guide posts 223 are disposed in the mounting slots 224. Thus, the symmetrically arranged guide posts 223 on both sides of the mating part 222 can keep the button 22 moving stably along the second direction, preventing the button 22 from tilting, shaking, or jamming during movement due to force on one side. This ensures precise engagement between the button 22 and other components of the water purifier, controlling the cover 21 to switch between open and closed states.

[0062] In one possible implementation, an elastic element 24 is provided between the button 22 and the cover 21, so that the button 22 can be evenly stressed under external force and can automatically reset after the external force is removed, ensuring that the door opening structure 2 can work normally.

[0063] Optionally, the elastic element 24 can be a spring, which is sleeved on the guide post 223 between the first side of the button 22 and the outer cover 211. When the button 22 is in the unlocked state, when an external force is applied to the button 22, the guide post 223 of the button 22 moves through the outer cover 211 in the second direction, and the spring is compressed; when the external force is removed, the spring drives the button 22 to reset.

[0064] Optionally, the elastic element 24 can be an elastic pad made of silicone or rubber. When the button 22 is pressed, the elastic pad is deformed by pressure and returns to its original shape after being released, pushing the button 22 back to its original position.

[0065] Optionally, the elastic element 24 can be a magnetic body, and the button 22 can be reset by using magnetic force to install magnets of the same or opposite poles on the inner cover 212 or the outer cover 211.

[0066] In one possible implementation, the button 22 has a waist hole 225; the outer cover 211 is provided with a connector, which passes through the waist hole 225 and connects to the inner cover 212, so that the button 22 can move along the extension direction of the waist hole 225.

[0067] exist Figure 3 From the perspective of [the viewpoint], each end of the second side of button 22 has a shoulder 226. When button 22 is in a free state, the shoulder 226 of button 22 abuts against the outer cover 211. A waist hole 225 can be provided near each shoulder 226, and the connector on the outer cover 211 passes through the waist hole 225 to form a sliding guide structure, allowing button 22 to move in the second direction.

[0068] In one possible implementation, the first side of the inner cover 212 is also provided with a support portion 2122, which is located near the waist hole 225 on the button 22.

[0069] Optionally, the support 2122 is a cavity structure with an opening on one side, and a connecting base 2123 is provided in the cavity for connecting with the connector in the outer cover 211. In this way, when the button 22 moves along the second direction, the support in the inner cover 212 and the outer cover 211 provide support for the two sides of the button 22 respectively, which can effectively prevent the button 22 from tilting during movement and further improve the stability of the connection between the button 22, the inner cover 212 and the outer cover 211.

[0070] In this embodiment, the waist hole 225 cooperates with the connector on the outer cover 211 to slide and guide the third and fourth sides of the button 22. The guide post 223 passes through the outer cover 211 to slide and guide the first side of the button 22. This ensures that the button 22 remains stable during the user's press and will not tilt or get stuck due to lateral force. Furthermore, when the button 22 is in the locked state, the support part 2122 in the inner cover 212, the outer cover 211, the guide shaft of the button 22, and the waist hole 225 cooperate to still ensure the stability of the button 22 and prevent the button 22 from tilting or falling out.
