Description

Technical Field

[0001] The invention relates to ice making equipment, in particular to an ice making machine. Background Art

[0002] An ice maker is a device that converts water or other liquids into ice cubes through refrigeration technology. Traditional ice makers have a relatively simple function and only have the function of making ice. Hydrogen-rich water, also known as hydrogen water or hydrogen water, is water containing dissolved hydrogen, which has anti-aging, improves metabolism and other effects. As people's living standards continue to improve, people's demand for the quality of goods is also gradually increasing. At present, ice makers only use pure water or filtered water to make ice. If you need to make hydrogen-rich ice, you need to first use a hydrogen-rich water machine to produce hydrogen-rich water, and then pour the hydrogen-rich water into a water dispenser for ice making. The use process is more troublesome and requires the configuration of multiple machines. The cost of ice making is high. Therefore, there is an urgent need for an ice maker that can make hydrogen-rich ice more easily. Summary of the invention

[0003] The object of the present invention is to provide an ice maker to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] An ice maker comprises: a raw water tank; a filter connected to the raw water tank, the filter having a pure water outlet; a pure water kettle, the pure water outlets of which are interconnected, the pure water kettle being connected to a water outlet pipe; a hydrogen production component interconnected with the pure water outlet, the hydrogen production component having a hydrogen outlet, the hydrogen outlet being connected to the water outlet pipe; an ice maker interconnected with the water outlet pipe; and a water outlet nozzle interconnected with the water outlet pipe.

[0006] This technical solution has at least the following beneficial effects: external water is added to the raw water tank, and the water output from the raw water tank is first filtered by the filter, and then pure water is output from the pure water outlet, part of the pure water flows into the pure water kettle, and the water outlet pipe connected to the pure water kettle can be directly output to the water outlet nozzle to output pure drinking water, or output to the ice maker to make ordinary ice; part of the pure water enters the hydrogen production component, and the hydrogen production component decomposes the pure water into hydrogen, which is output from the hydrogen outlet to the water outlet pipe, and pure water with hydrogen can be output from the water outlet pipe. At this time, the pure water with hydrogen can be directly output from the water outlet nozzle, or the pure water with hydrogen can be input into the ice maker to make hydrogen-rich ice in the ice maker. In this way, water or ice containing hydrogen can be output from the ice maker according to usage needs, and the usage functions are more diverse, which can better meet different usage needs and improve the usage experience of the ice maker.

[0007] As a further improvement of the above technical solution, the hydrogen production component includes a water circuit plate, a water storage tank and an electrolyzer, the water storage tank and the pure water outlet are interconnected by a pipeline, a water inlet pipe is formed in the water circuit plate, the water outlet pipe is arranged in the water circuit plate, one end of the water inlet pipe is connected to the water storage tank, and the other end of the water inlet pipe is connected to the water outlet pipe, and a hydrogen joint and a water outlet joint are sequentially arranged on the water outlet pipe in a direction away from the water inlet pipe, the electrolyzer is connected to the water circuit plate, the hydrogen outlet is formed on the bottom side of the electrolyzer, the hydrogen outlet and the hydrogen joint are interconnected, a water inlet joint is arranged on the top side of the electrolyzer, the water inlet joint and the water storage tank are interconnected by a pipeline, and the water outlet joint is respectively connected to the ice maker and the water outlet nozzle by pipelines. The water inlet pipe and the water outlet pipe are directly integrated on the water circuit board, which effectively reduces the risk of leakage in the pipe connection and is conducive to simplifying the pipe connection structure. The electrolyzer is installed on the plate body, and the overall combination forms a hydrogen production module with a simple structure and more convenient maintenance. When hydrogen production is not needed, part of the pure water in the pure water kettle directly enters the water outlet pipe and is output from the water outlet joint to the ice maker or water outlet nozzle; and part of the pure water flowing out of the pure water kettle enters the water storage tank for storage. When hydrogen production is needed, the pure water in the water storage tank is input into the electrolyzer from the water inlet joint on the top side of the electrolyzer, and the pure water is electrolyzed in the electrolyzer. The obtained hydrogen enters the water outlet pipe through the hydrogen outlet through the hydrogen joint, dissolves in the pure water in the water outlet pipe, and then is output from the water outlet joint to the ice maker or water outlet nozzle.

[0008] As a further improvement of the above technical solution, the water outlet pipe includes a first horizontal flow section, a narrowing section, an expansion section and a second horizontal flow section connected in sequence, the water inlet pipe is connected to the first horizontal flow section, the inner diameter of the narrowing section gradually decreases in the direction away from the first horizontal flow section, the hydrogen joint is connected between the narrowing section and the expansion section, the inner diameter of the expansion section gradually increases in the direction away from the narrowing section, and the water outlet joint is connected to the second horizontal flow section. Pure water enters the first horizontal flow section, and when entering the narrowing section, the pressure of the pure water in the narrowing section gradually increases due to the gradual reduction of the inner diameter of the narrowing section. When the compressed pure water enters the expansion section, the flow rate is relatively fast. At this time, the hydrogen in the hydrogen joint can be quickly sucked out and enter the expansion section together. When the pure water mixed with hydrogen diffuses in the expansion section, it can promote the diffusion and fusion of hydrogen in the pure water, and then output it outward in the second horizontal flow section, so that the effect of hydrogen input into the pure water pipe and mixing and dissolving with pure water can be improved.

[0009] As a further improvement of the above technical solution, an instant heating module is arranged between the water outlet and the water outlet pipe. When the water outlet pipe outputs to the water outlet, it can be selected whether to start the instant heating module. When the instant heating module works, the water output from the water outlet pipe can be heated, and hot water is output from the water outlet; when the instant heating module does not work, normal temperature water is output from the water outlet.

[0010] As a further improvement of the above technical solution, the ice maker includes an ice-making shell, an ice storage box, a refrigeration device, a rotating drive member and an ice-making box, the ice storage box is connected to the ice-making shell, the water outlet pipe is connected to the bottom of the ice-making shell, the ice-making box is rotatably connected to the ice-making shell, the ice-making box is located above the ice storage box, a water pumping pipe is provided at the bottom of the ice-making shell, the water pumping pipe extends to the top of the ice-making box, the refrigeration device has a refrigeration pipe fixed above the ice-making box, a plurality of ice-making heads extending into the ice-making box are provided on the bottom side of the refrigeration pipe, the rotating drive member is provided on the ice-making shell, the rotating drive member is transmission-connected to the ice-making box, and the rotating drive member can drive the ice-making box to rotate around the refrigeration pipe. Part of the pure water output from the pure water kettle flows into the bottom of the ice-making shell. When ice making is needed, the pure water at the bottom of the ice-making shell is pumped into the ice-making box by using a pumping pipe. The pure water submerges the multiple ice-making heads extending into the ice-making box. The refrigeration device works, and the refrigeration pipe absorbs heat, so that the pure water in the ice-making box gradually condenses into ice cubes on the outside of the ice-making heads. When the ice cubes on the outside of the ice-making heads condense to a certain thickness or the ice making time has passed, the refrigeration pipe releases heat, so that the ice cubes are partially dissolved at the position connected to the outside of the ice-making heads. At this time, the ice cubes fall out and fall into the ice-making box. The rotating drive member drives the ice-making box to rotate, and pours the ice cubes in the ice box into the ice-making shell to achieve ice making.

[0011] As a further improvement of the above technical solution, an ice melting return pipe is provided at the bottom of the ice storage box, and the water outlet direction of the ice melting return pipe is toward the bottom of the ice making shell. The cold water after the ice cubes in the ice storage box are melted can be input into the ice making shell through the ice melting return pipe, so that the water at the bottom of the ice storage box can be kept at a low temperature, the ice making time can be shortened, and the utilization rate of water converted into ice can be improved.

[0012] As a further improvement of the above technical solution, a cold water return pipe is provided at the bottom of the ice making box, and the water outlet direction of the cold water return pipe is toward the bottom of the ice making shell. When the water in the ice storage box needs to be drained, the water can be input to the refrigeration shell through the cold water return pipe for recycling, and the cold capacity of the water is more fully utilized, so that the water at the bottom of the ice storage box is kept at a low temperature.

[0013] As a further improvement of the above technical solution, a sterilizing lamp is arranged in the ice-making shell, which can be used to sterilize the inside of the ice-making shell to reduce the growth of bacteria inside, and can better maintain the cleanliness of the inside of the ice-making shell when the ice-making shell is not used for a long time.

[0014] As a further improvement of the above technical solution, the rotary drive member is connected to a paddle in a transmission manner, and travel switches are respectively arranged on both sides of the paddle on the ice-making shell. The rotary drive member can drive the paddle to rotate and make the paddle abut against the trigger end of any one of the travel switches, and the two travel switches are respectively electrically connected to the rotary drive member. When the rotary drive member drives the ice storage box to rotate, the paddle can be driven to rotate synchronously. When the ice storage box rotates to the right position, the paddle abuts against the trigger end of a travel switch. At this time, the rotary drive member can be controlled by the travel switch to stop working, thereby improving the accuracy of the activity stroke of the ice storage box.

[0015] As a further improvement of the above technical solution, a drain valve is provided on the bottom side of the ice making shell. When the inside of the ice making shell needs to be cleaned or the water needs to be changed, the water inside the ice making shell can be drained from the drain valve, thereby reducing bacterial growth and improving the cleanliness of the inside of the ice making shell.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0029] Reference Figure 1 and Figure 2 An ice maker comprises: a raw water tank 1; a filter 2 connected to the raw water tank 1, the filter 2 having a pure water outlet; a pure water kettle 3, the pure water outlets of which are interconnected, and the pure water kettle 3 is connected to a water outlet pipe 512; a hydrogen production component interconnected with the pure water outlet, the hydrogen production component having a hydrogen outlet, and the hydrogen outlet is connected to the water outlet pipe 512; an ice maker 4 connected to the water outlet pipe 512; a water outlet nozzle connected to the water outlet pipe 512.

[0030] In this ice maker, external water is added to the raw water tank 1, and the water output from the raw water tank 1 is first filtered by the filter 2, and then pure water is output from the pure water outlet, and part of the pure water flows into the pure water kettle 3, and the water outlet pipe 512 connected to the pure water kettle 3 can be directly output to the water outlet to output pure drinking water, or output to the ice maker 4 to make ordinary ice; part of the pure water enters the hydrogen production component, and the hydrogen production component decomposes the pure water into hydrogen, which is output from the hydrogen outlet to the water outlet pipe 512, and the pure water with hydrogen can be output from the water outlet pipe 512. At this time, the pure water with hydrogen can be directly output from the water outlet, or the pure water with hydrogen can be input into the ice maker 4 to make hydrogen-rich ice in the ice maker 4. In this way, water or ice containing hydrogen can be output from the ice maker according to the needs of use, and the use functions are more diverse, which can better meet different use needs and improve the use experience of the ice maker.

[0031] The hydrogen production component is mainly used to electrolyze pure water to produce oxygen and input hydrogen into the pure water. In this embodiment, Figure 3 As shown, the hydrogen production component includes a waterway plate 51, a water storage tank 52 and an electrolyzer 53. The water storage tank 52 and the pure water outlet are connected to each other through a pipeline. A water inlet pipe 511 is formed in the waterway plate 51, and the water outlet pipe 512 is arranged in the waterway plate 51. One end of the water inlet pipe 511 is connected to the water storage tank 52, and the other end of the water inlet pipe 511 is connected to the water outlet pipe 512. The upper edge of the water outlet pipe 512 is away from the water inlet pipe 511. A hydrogen connector 513 and a water outlet connector 514 are sequentially arranged, the electrolytic cell 53 is connected to the water plate 51, the hydrogen outlet is formed on the bottom side of the electrolytic cell 53, the hydrogen outlet and the hydrogen connector 513 are interconnected, a water inlet connector 531 is arranged on the top side of the electrolytic cell 53, the water inlet connector 531 and the water storage tank 52 are interconnected through pipelines, and the water outlet connector 514 is respectively connected to the ice maker 4 and the water outlet nozzle through pipelines. The water inlet pipe 511 and the water outlet pipe 512 are directly integrated on the water circuit board 51, which effectively reduces the risk of pipeline connection leakage and is conducive to simplifying the pipeline connection structure. The electrolyzer 53 is installed on the plate body, and the overall combination forms a hydrogen production module with a simple structure and more convenient maintenance. When hydrogen production is not needed, part of the pure water in the pure water kettle 3 directly enters the water outlet pipe 512 and is output from the water outlet joint 514 to the ice maker 4 or the water outlet nozzle; and part of the pure water flowing out of the pure water kettle 3 enters the water storage tank 52 for storage. When hydrogen production is needed, the pure water in the water storage tank 52 is input into the electrolyzer 53 from the water inlet joint 531 on the top side of the electrolyzer 53, and the pure water is electrolyzed in the electrolyzer 53. The obtained hydrogen enters the water outlet pipe 512 from the hydrogen outlet through the hydrogen joint 513, dissolves in the pure water in the water outlet pipe 512, and then is output from the water outlet joint 514 to the ice maker 4 or the water outlet nozzle.

[0032] Further, such as Figure 4As shown, the water outlet pipe 512 includes a first horizontal flow section 5121, a narrowing section 5122, an expansion section 5123 and a second horizontal flow section 5124 which are connected in sequence, the water inlet pipe 511 is connected to the first horizontal flow section 5121, the inner diameter of the narrowing section 5122 gradually decreases in the direction away from the first horizontal flow section 5121, the hydrogen connector 513 is connected between the narrowing section 5122 and the expansion section 5123, the inner diameter of the expansion section 5123 gradually increases in the direction away from the narrowing section 5122, and the water outlet connector 514 is connected to the second horizontal flow section 5124. Pure water enters the first horizontal flow section 5121, and when it enters the narrowing section 5122, the inner diameter of the narrowing section 5122 gradually decreases, and the pressure of the pure water in the narrowing section 5122 gradually increases. When the compressed pure water enters the expansion section 5123, the flow rate is faster. At this time, the hydrogen in the hydrogen connector 513 can be quickly sucked out and enter the expansion section 5123 together. When the pure water mixed with hydrogen diffuses in the expansion section 5123, it can promote the diffusion and fusion of hydrogen in the pure water, and then output it to the outside in the second horizontal flow section 5124. In this way, the effect of hydrogen input into the pure water pipe and mixed with pure water can be improved.

[0033] In order to further enrich the functions of the whole machine, in this embodiment, an instant heating module is arranged between the water outlet and the water outlet pipe 512. The instant heating module includes a heating pipe, and a heating source is arranged outside the heating pipe. The heating source can be a heating electrical element such as an electric heating pipe and a heating wire, and the heating pipe connects the water outlet and the water outlet pipe 512 to each other. When the water outlet pipe 512 outputs to the water outlet, it can be selected whether to start the instant heating module to work. When the instant heating module works, the water output from the water outlet pipe 512 can be heated, and hot water is output from the water outlet; when the instant heating module does not work, the water output from the water outlet is normal temperature water.

[0034] As a specific embodiment of the ice maker 4, Figure 5 and Figure 6As shown, the ice maker 4 includes an ice-making shell 41, an ice storage box 42, a refrigeration device, a rotary drive member 44 and an ice-making box 45. The ice storage box 42 is connected to the ice-making shell 41, the water outlet pipe 512 is connected to the bottom of the ice-making shell 41, the ice-making box 45 is rotatably connected to the ice-making shell 41, the ice-making box 45 is located above the ice storage box 42, a water pumping pipe is provided at the bottom of the ice-making shell 41, and the water pumping pipe extends to the top of the ice-making box 45, the refrigeration device has a refrigeration pipe 43 fixed above the ice-making box 45, a plurality of ice-making heads 431 extending into the ice-making box 45 are provided at the bottom side of the refrigeration pipe 43, the rotary drive member 44 is provided on the ice-making shell 41, the rotary drive member 44 is transmission-connected to the ice-making box 45, the rotary drive member 44 can drive the ice-making box 45 to rotate around the refrigeration pipe 43, and the rotary drive member 44 can be a driving source such as a rotary cylinder and a rotary motor. Part of the pure water output from the pure water kettle 3 flows into the bottom of the ice-making shell 41. When ice making is needed, the pure water at the bottom of the ice-making shell 41 is pumped into the ice-making box 45 by using a pumping pipe. Of course, the water flow delivery in the above-mentioned various methods needs to be equipped with a delivery pump to provide delivery power. For example, a delivery pump is provided at the bottom of the ice-making shell 41. The delivery pump pumps the water at the bottom of the ice-making shell 41 to the pumping pipe. The pure water immerses the multiple ice-making heads 431 extending into the ice-making box 45. The refrigeration device works and the refrigeration pipe 43 absorbs heat, so that the pure water in the ice box 45 gradually condenses into ice cubes on the outside of the ice head 431. When the ice cubes on the outside of the ice head 431 condense to a certain thickness or the ice making time has passed, the refrigeration tube 43 releases heat, so that the ice cubes are partially melted at the position connected to the outside of the ice head 431. At this time, the ice cubes fall out and fall into the ice box 45. The rotating driving part 44 drives the ice box 45 to rotate, and the ice cubes in the ice box 45 are poured out into the ice shell 41 to achieve ice making.

[0035] Naturally, the refrigeration pipe 43 in the refrigeration device can be used for both cooling and heating. For example, the refrigeration device includes a compressor, a refrigeration pipe 43, a capillary tube and a condenser which are connected in a circular manner. When a low-temperature refrigerant is transported to the refrigeration pipe 43, this is the process of making ice on the outside of the ice-making head 431. When a high-temperature refrigerant is transported to the refrigeration pipe 43, this is the process of defrosting the ice-making head 431.

[0036] In some embodiments, an ice melting return pipe 421 is provided at the bottom side of the ice storage box 42, and the water outlet direction of the ice melting return pipe 421 is toward the bottom of the ice making shell 41. Of course, a control valve can be provided in the ice melting return pipe 421 to control the on and off of the water flow. The cold water after the ice cubes in the ice storage box 42 are melted can be input into the ice making shell 41 through the ice melting return pipe 421, so that the water at the bottom of the ice storage box 42 can be kept at a low temperature, the ice making time can be shortened, and the utilization rate of water converted into ice can be improved.

[0037] In some embodiments, a cold water return pipe 451 is provided at the bottom of the ice making box 45, and the water outlet direction of the cold water return pipe 451 is toward the bottom of the ice making shell 41. Similarly, a control valve can be provided in the cold water return pipe 451 to control the on and off of the water flow. When the water in the ice storage box 42 needs to be drained, the water can be input to the cooling shell through the cold water return pipe 451 for recycling, and the coldness of the water can be more fully utilized, so that the water at the bottom of the ice storage box 42 is kept at a low temperature.

[0038] In some embodiments, a germicidal lamp 411 is provided in the ice-making shell 41. The germicidal lamp 411 can be used to sterilize the inside of the ice-making shell 41 to reduce the growth of internal bacteria, especially when the ice-making shell 41 is not used for a long time, the cleanliness of the inside of the ice-making shell 41 can be better maintained.

[0039] In order to ensure that the ice storage box 42 can be moved to the right position, in this embodiment, the rotating driving member 44 is connected to a paddle in a transmission manner, and the ice-making shell 41 is provided with travel switches on both sides of the paddle. The rotating driving member 44 can drive the paddle to rotate and make the paddle abut against the trigger end of any one of the travel switches, and the two travel switches are electrically connected to the rotating driving member 44. When the rotating driving member 44 drives the ice storage box 42 to rotate, the paddle can be driven to rotate synchronously. When the ice storage box 42 rotates to the right position, the paddle abuts against the trigger end of a travel switch. At this time, the rotating driving member 44 can be feedback-controlled by the travel switch to stop working, so that the accuracy of the movable travel of the ice storage box 42 can be improved.

[0040] In some embodiments, a drain valve is provided at the bottom of the ice-making shell 41. When the inside of the ice-making shell 41 needs to be cleaned or the water needs to be changed, the water inside the ice-making shell 41 can be drained from the drain valve, thereby reducing bacterial growth and improving the cleanliness of the inside of the ice-making shell 41.

[0041] In actual use, the raw water tank 1, the filter 2, the pure water kettle 3, the hydrogen production component and the ice maker 4 are all located in the housing 6. Figures 7 to 9 As shown, a first hole is provided on the front side of the shell 6, a side fixing edge 61 is provided on the inner side of the first hole of the shell 6, a first snap-in hole 611 is provided on the side fixing edge 61, and a supporting section 6 protruding from the first hole is provided on the bottom side of the shell 6; a first snap 71 is provided on the surface cover 7 at a position directly opposite to the first snap-in hole 611, the first snap 71 is snapped downwardly to the first snap-in hole 611, and a limiting protrusion 72 is provided on the surface cover 7 facing the first hole, and the limiting protrusion abuts against the top side of the supporting section 6.

[0042] In this panel assembly, after the cover 7 is connected to the shell 6, the cover 7 closes the first hole on the shell 6, and the internal space enclosed by the two can be used to load electrical components such as the raw water tank 1, the filter 2, the pure water kettle 3, the hydrogen production component and the ice maker 4. When it is necessary to maintain the internal electrical components, the cover 7 can be moved upward relative to the shell 6, so that the first buckle 71 is upwardly disengaged from the first buckle hole 611, thereby opening the first hole. When it is necessary to reinstall the cover 7 into the shell 6, the cover 7 is pressed against the side fixing edge 61 of the shell 6 located on the inner side of the first hole, and the side fixing edge is used to fix the cover 7. 61 limits the installation position of the face cover 7, and buckles the first buckle 71 downward into the first buckle hole 611. By utilizing the cooperation between the two, the face cover 7 can be limited from slipping out of the shell 6, and the limiting protrusion can abut against the top side of the supporting section 6, limiting the face cover 7 from continuing to move downward, and providing support for the bottom position of the face cover 7, so that the face cover 7 and the shell 6 can be quickly connected. The installation limit provided by the side fixed edge 61 and the support provided by the supporting section 6 can improve the stability of the overall structural connection, reduce the exposure of the structure, improve the overall appearance, and make it more practical.

[0043] In order to make the top of the cover 7 and the top of the shell 6 more tightly connected, in this embodiment, the shell 6 is provided with an upper support edge 63 at the top side of the first hole, and a positioning hole 631 is provided at the top side of the upper support edge 63. A positioning block 73 is provided at the top side of the cover 7 facing the positioning hole 631, and the positioning block 73 is connected in cooperation with the positioning hole 631. When the cover 7 is installed into the shell 6, the upper support edge 63 at the top side of the shell 6 can play a supporting and limiting role for the cover 7, and can limit the downward installation stroke of the cover 7 at the top position of the cover 7. After the cover 7 is installed in place on the shell 6, the positioning block 73 at the top side of the cover 7 is connected in cooperation with the positioning hole 631 at the top side of the upper support edge 63, so that the cover 7 cannot be directly removed outward, thereby improving the stability of the cover 7 when it is installed into the shell 6.

[0044] After the first buckle 71 and the first buckle hole 611 are buckled together, the cover 7 and the housing 6 can be further fastened to each other. Specifically, a connecting piece is penetrated upward from the bottom side of the supporting section 6, and the connecting piece is matched and connected in the limiting protrusion 72. In practical applications, the connecting piece can be a screw or a bolt. After the cover 7 is installed in the housing 6, a connecting piece can be penetrated upward from the bottom side of the supporting section 6, so as to further lock the cover 7 to the supporting section 6 and prevent the cover 7 from directly falling out.

[0045] The first snap-fitting hole 611 can be an opening in a rectangular or elliptical shape. In order to facilitate the connection and mutual stabilization of the first snap-fitting hole 611 with the first snap-fitting hole 611, in the present embodiment, the first snap-fitting hole 611 includes a pre-installed section 6111, a reduction section 6112 and a positioning section 6113 arranged in sequence from top to bottom. The lateral width of the pre-installed section 6111 is greater than the lateral width of the positioning section 6113, and the lateral width of the reduction section 6112 gradually decreases downward. The first snap-fitting hole 71 is located in the positioning section 6113, and the end of the first snap-fitting hole 71 extending into the positioning section 6113 has a snap-fitting portion protruding downward. When the first buckle 71 on the face cover 7 is matched and connected to the first snap hole 611 of the side fixing edge 61, the first buckle 71 is first inserted into the pre-installed section 6111. Since the lateral width of the pre-installed section 6111 is relatively large, the first buckle 71 can be easily matched with the first snap hole 611, so that the face cover 7 is pre-positioned on the shell 6. Then the face cover 7 is moved downward so that the first buckle 71 enters into the positioning section 6113 along the shrinking section 6112 whose lateral width gradually decreases downward. The positioning section 6113 with a smaller lateral width is used to limit the left and right movement of the first buckle 71, and the downward protruding buckle portion of the first buckle 71 is used to limit the face cover 7 from directly detaching from the shell 6 outward, thereby improving the stability of the connection between the face cover 7 and the shell 6.

[0046] The cover 7 can be a whole plate structure, and can be further designed as a split structure with a detachable plate body. Specifically, the cover 7 is provided with a second hole, and the cover 7 is detachably connected to a decorative plate 8 at the position of the second hole. The cover 7 is also provided with a detachable decorative plate 8. After the decorative plate 8 is removed from the cover 7, some electrical components inside the cover 7 can be adjusted and maintained through the second hole, thereby improving the overall convenience of use.

[0047] As a way of detachably connecting the decorative panel 8 to the face cover 7, in the present embodiment, the face cover 7 is provided with a side limiting edge 74 at the inner side of the second hole, the top of the side limiting edge 74 is inclined and extends away from the shell 6, a second snap-in hole 741 is provided on the side limiting edge 74, the top of the decorative panel 8 is inclined and extends away from the shell 6, a second snap-in hole 741 is provided on the decorative panel 8, the decorative panel 8 is provided with a second snap-in hole 81 at a position opposite to the second snap-in hole 741, the decorative panel 8 is abutted against the side limiting edge 74, and the second snap-in hole 741 is upwardly snap-in connected to the second snap-in hole 741. When installing the decorative panel 8 into the face cover 7, the decorative panel 8 is installed into the face cover 7 from bottom to top, so that the second clip 81 is upwardly clipped into the second clip hole 741. At this time, the inclined extending portion of the top of the decorative panel 8 abuts against the inclined extending position of the top of the side limiting edge 74, thereby limiting the upward movement of the decorative panel 8. The second clip 81 and the second clip hole 741 are mutually matched and connected, so as to achieve a stable installation of the decorative panel 8 on the face cover 7.

[0048] In practical applications, there are multiple first buckles 71 and multiple first snap holes 611, and the first buckles 71 and the first snap holes 611 form a connection group. Multiple connection groups can be provided between the cover 7 and the shell 6 to improve the connection stability between the cover 7 and the shell 6. Figure 5 As shown, there are multiple numbers of the second buckle 81 and the second snap-in hole 741, respectively. In at least one of the second buckle 81 and the second snap-in hole 741 that cooperate with each other, a positioning protrusion 811 is provided on one side of the second buckle 81, and a positioning slot 7411 is provided on one side of the second snap-in hole 741. The positioning protrusion 811 is matched and connected in the positioning slot 7411. In application, since the second buckle 81 is a structural member protruding from the face cover 7, it itself can produce a certain elastic deformation along the width direction of the second snap-in slot, so that the positioning protrusion 811 can enter and exit the positioning slot 7411. A second clip 81 cooperates with a second clip hole 741 to form a clip group. A plurality of clip groups are arranged between the decorative panel 8 and the face cover 7 to form connection limitations at different positions. In at least one clip group, a positioning protrusion 811 is also arranged on the second clip 81, and a positioning slot 7411 is also arranged in the second clip hole 741. The positioning protrusion 811 cooperates with the positioning slot 7411 to maintain the second clip 81 in a state of being connected to the second clip hole 741, so that the decorative panel 8 is installed more firmly on the face cover 7.

[0049] Furthermore, a slot 75 is provided on the side of the bottom of the cover 7 away from the housing 6, and an anti-drop cap is provided on the top of the slot 75. An insert block is provided on the side of the bottom of the decorative plate 8 facing the housing 6, and the insert block passes through the slot 75 and is inserted into the anti-drop cap. When the decorative plate 8 is connected to the cover 7 from bottom to top, the insert block at the bottom of the decorative plate 8 passes through the slot 75 at the bottom of the cover 7 and is inserted into the anti-drop cap, thereby limiting the position of the bottom of the decorative plate 8, which is conducive to preventing the bottom of the decorative plate 8 from being separated from the bottom of the cover 7, and further improving the stability of the connection between the decorative plate 8 and the cover 7.

[0050] In some embodiments, a limiting column 82 is provided on the side of the decorative plate 8 facing the housing 6, and a limiting plate 64 is provided in the housing 6 facing the second hole. The limiting plate 64 is provided with a limiting hole 641 extending in the up-down direction, and the limiting column 82 is inserted into the limiting hole 641. When the decorative plate 8 and the cover plate are connected to the housing 6 as a whole, the limiting column 82 is inserted into the limiting hole 641. The middle position of the decorative plate 8 can be limited by the cooperation of the limiting column 82 and the limiting hole 641. When the first buckle 71 is downwardly connected to the first clamping hole 611, the limiting column 82 also moves downward in the limiting hole 641 to the position. At this time, the downward movement of the limiting column 82 can be limited, thereby ensuring the travel limit of the first buckle 71 and the first clamping hole 611 after mutual cooperation.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
