The top cover shell 200 is installed at the upper opening of the inner washing cavity to seal the inner washing cavity.

[0027] A shelf 140 is horizontally arranged at the bottom of the washing cavity, and the shelf 140 is used to support milk bottles waiting to be cleaned.

[0028] A support stand 110 is vertically arranged in the washing cavity, one end of the support stand 110 is connected to the bottom of the washing cavity, and the other end extends upward to the upper position of the washing cavity.

[0029] The washing device involved in the present application can be single-layer or double-layer. The single-layer washing device refers to a single-layer shell structure in which only an inner cavity shell 100 is arranged on the outside of the washing inner cavity.

[0030] A double-layer washing device refers to a double-layer shell structure formed on the outside of the washing inner cavity. The inner cavity shell 100 in the present application is specifically an inner tank. An outer shell (not shown) is also provided on the outside of the inner cavity shell 100 according to actual usage requirements. A connecting outer edge extending outward is formed on the upper side of the inner cavity shell 100. The inner cavity shell is connected to the outer shell through the connecting outer edge, and the bottom of the outer shell is connected to the support base 300 or is integrally formed with the support base 300.

[0031] The support base 300 is disposed at the bottom of the inner cavity shell 100 . The support base 300 is a shell structure with an upper opening. An installation cavity is formed between the support base 300 and the washing bottom wall 160 of the inner cavity shell 100 .

[0032] A top cover inner cavity is formed in the top cover outer shell 200, and the top cover inner cavity is a closed chamber structure. The driving component 400 is partially installed in the top cover inner cavity. Compared with other washing devices, the main power components of the washing device involved in the present application are installed in the top cover inner cavity.

[0033] The top cover shell 200 specifically includes a shell body and a device cover detachably connected to the device body. During installation, after the power components and the like are fixed in the inner cavity of the top cover, the device cover is placed on top of the shell body to seal the inner cavity of the top cover.

[0034] The driving component 400 provides power for the washing and / or draining process of the washing device. The driving component 400 includes a driving member 410 and a transmission member 440. The driving member 410 is specifically a driving motor, which is arranged in the inner cavity of the top cover. The driving member 410 is vertically arranged in the inner cavity of the top cover. The output end of the driving member 410 extends downward to the outside of the top cover outer shell and is detachably connected to the transmission member 440 arranged in the washing inner cavity.

[0035] Specific reference Figure 2 , Figure 4 as well as Figure 5The transmission member 440 is rotatably connected to the supporting portion 110, a first docking portion 420 is provided at the output end of the driving member 410, a second docking portion 430 is provided at the upper end of the transmission member 440, a cleaning impeller 450 and / or a drainage impeller 460 are connected to the lower end of the transmission member 440, and when the top cover shell 200 is connected to the inner cavity shell 100, the first docking portion 420 is connected to the second docking portion 430, so that the driving member 410 drives the cleaning impeller 450 and / or the drainage impeller 460 to rotate.

[0036] In order to protect the transmission member 440, the present application designs the support stand 110 to be a straight cylindrical structure, with a penetrating support cavity formed inside. The transmission member 440 is specifically a transmission rod, which is arranged in the support cavity. The top of the transmission rod extends to the top of the support stand 110, and the second docking portion 430 is located above the support stand 110.

[0037] Before washing, the top cover shell 200 is first removed from the inner cavity shell 100. During disassembly, the first docking part 420 is separated from the second docking part 430, and then the bottle to be cleaned is placed in the washing inner cavity. Finally, the top cover shell 200 is fixed on the inner cavity shell 100, and the first docking part 420 and the second docking part 430 are reconnected. The driving part 410 drives the transmission part 440 to rotate, and then drives the cleaning impeller 450 and / or the drainage impeller 460 below to rotate, so as to achieve the purpose of washing or drainage.

[0038] Since the driving member 410 involved in the washing device is a low-power driving motor, which is relatively light in weight, the disassembly and assembly of the top cover shell 200 from the inner cavity shell 100 will not impose a great labor burden on the operator.

[0039] Alternatively, in some other embodiments, a door may be provided on the side wall of the inner cavity housing 100 to facilitate users to take in and place items to be cleaned.

Specifically, a plurality of docking protrusions are dispersedly arranged on the circumference of the first docking portion 420, a docking cavity opening upward is formed on the second docking portion 430, and a plurality of vertically arranged docking recesses are correspondingly arranged on the side wall of the docking cavity, and the docking protrusions correspond to the docking recesses one by one.

[0041] When the top cover shell 200 is connected to the inner cavity shell 100 from top to bottom, each docking protrusion on the first docking portion 420 is inserted into the corresponding docking recess, thereby realizing the connection between the first docking portion 420 and the second docking portion 430 .

[0042] In some embodiments of the present application, a cleaning impeller 450 is connected to the bottom of the transmission member 440, which is used to provide power for spraying washing water of the washing device.

[0043] refer to Figure 6-Figure 8 A spray assembly 600 is arranged in the washing cavity, and the spray assembly 600 includes a spray pump shell and a spray arm 610. The spray pump shell is specifically connected to the washing bottom wall 160. A pump shell inner cavity is formed in the spray pump shell. The cleaning impeller 450 is installed in the pump shell inner cavity. The transmission member 440 extends from the top of the spray pump shell to the pump shell inner cavity. The cleaning impeller 450 is fixed on the transmission member 440. As the transmission member 440 rotates, the cleaning impeller 450 rotates accordingly.

[0044] A spray support portion 631 is provided above the spray pump housing, and the spray arm 610 is rotatably connected to the spray support portion 631. Spray holes are provided on the spray wall for outputting washing water into the washing inner cavity.

[0045] refer to Fig. 9 The inner cavity of the pump casing includes a water collecting portion 601 and a water passage 602 arranged on the periphery of the water collecting area. The cleaning impeller 450 is arranged in the water collecting portion 601. Each water passage 602 extends outward along the tangent direction of the water collecting portion 601 to form a circular involute structure with the water collecting portion 601. The spray support portion 631 is arranged at the end of the water passage 602.

[0046] The pump casing inner cavity is formed inside the spray pump casing, and the overall shape of the spray pump casing is adapted to the pump casing inner cavity.

[0047] For details, please refer to Figure 8 The spray pump housing includes an upper housing 630 and a lower housing 640 , the upper housing 630 and the lower housing 640 are detachably connected, and a spray support portion 631 is formed on the upper housing 630 .

[0049] The inner cavity of the pump casing is connected to the washing cavity, and an opening is provided on the lower casing 640 for allowing the washing water in the washing cavity to enter the inner cavity of the pump casing.

[0050] In other embodiments, a filter element 150 is further provided between the spray pump housing and the spray arm 610 , and filter holes (not shown) are formed on the filter element 150 for filtering residues to avoid clogging the drain pipe.

[0051] A support platform 164 is provided at a lower position of the washing cavity. The support platform 164 is specifically an annular protrusion on the side wall of the washing cavity. The peripheral side of the filter element 150 is connected to the support platform 164 .

[0052] In some embodiments, two water passages 602 are provided on the peripheral side of the water collecting portion 601, and the two water passages 602 are symmetrically arranged on both sides of the water collecting portion 601, and the extension directions of the two water passages 602 on the water collecting portion 601 are consistent, and the offset direction of each water passage 602 relative to the water collecting portion 601 is consistent with the rotation direction of the cleaning impeller 450, so that when the cleaning impeller 450 rotates, the water flow is guided into each water passage 602, and finally sprayed from the spray arm 610 into the washing cavity.

[0053] The end of each water passage 602 is respectively connected to a spray arm 610, and the spray arm 610 is rotatably connected to the spray support part 631, so that when the washing water is sprayed from the spray arm 610, the spray arm 610 rotates relative to the spray support part 631 under the reaction of the water flow, thereby improving the uniformity of washing.

[0054] The spray arm 610 is also provided with a spray column 620 extending upward, and a water outlet is provided on the top of the spray column 620. The top of the spray column 620 is used to support small-caliber items to be cleaned, such as baby bottles. The washing water output from the water outlet on the spray column 620 can be directly transported to the inner cavity of the baby bottle to be cleaned, thereby achieving the purpose of cleaning the inner cavity.

[0055] The spray support part 631 is integrally formed with the upper shell 630 . The spray support part 631 is a through cylindrical structure. A water hole is formed on the side wall of the spray support part 631 . The water in the water channel 602 is transported to the spray arm 610 through the spray support part 631 .

[0056] refer to Figure 2 , Figure 4 as well as Figure 6 In other embodiments, a drainage impeller 460 is connected to the end of the transmission member 440 to drain the water in the washing cavity after washing is completed.

[0057] Specifically, a downwardly extending drainage recess 161 is formed on the washing bottom wall 160 , and the drainage recess 161 is located in the middle of the washing bottom wall 160 . A drainage interface 162 is provided on the side wall of the drainage recess 161 , and the drainage interface 162 is externally connected to a drainage pipe.

[0058] The design direction of the drainage interface 162 is consistent with the tangent direction of the drainage recess 161, and the drainage interface 162 and the drainage recess 161 form a circular involute structure. When the cleaning impeller 450 and the drainage impeller 460 are connected to the transmission member 440 at the same time, the tangent direction of the drainage interface 162 on the drainage recess 161 is opposite to the deflection direction of the water passage 602 relative to the water collection portion 601.

[0059] An assembly end is formed at the bottom of the transmission member 440, and an assembly section is formed on the outer wall of the assembly end. The drainage impeller 460 includes a connecting portion and drainage blades formed on the peripheral side of the connecting portion, and an assembly hole matching the shape of the assembly end is formed on the connecting portion.

[0060] During the cleaning process, the cleaning impeller 450 and the drainage impeller 460 both rotate along the first direction. At this time, the water flow in the water collecting part 601 enters the water passage 602. When the drainage impeller 460 rotates along the first direction, the water flow direction is opposite to the opening direction of the drainage interface 162, and no drainage is performed.

[0061] During the drainage process, the cleaning impeller 450 and the drainage impeller 460 both rotate along the second direction. At this time, the water flow direction in the water collecting portion 601 is opposite to the opening direction of the water passage 602, and no water enters the water passage 602. The water flow direction in the drainage recess 161 is opposite to the opening direction of the drainage interface 162. Under the action of the drainage impeller 460, the water in the drainage recess 161 enters the drainage pipe through the drainage interface 162.

[0062] In other words, the drainage recess 161 is located directly below the transmission member 440, and the drainage impeller 460 is disposed at the bottom of the transmission member 440. The drainage impeller 460 is rotatably connected in the drainage recess 161 to discharge the washing water from the drain pipe.

[0063] The drain pipe extends along the tangent direction of the drain recess 161 , and the extending direction of the drain pipe is opposite to the extending direction of each water passing portion.

[0064] During washing, the transmission member 440 drives the washing impeller and the drainage impeller 460 to rotate along the first direction, and the washing water in the water collecting portion 601 enters the water passing portion under the action of the washing impeller.

[0065] During drainage, the transmission member 440 drives the washing impeller and the drainage impeller 460 to rotate in a second direction opposite to the first direction, and the water in the drainage recess 161 enters the drainage pipe under the action of the drainage impeller 460 .

[0066] The water inlet of the washing device is from top to bottom, and a water inlet pump 800 is also arranged in the inner cavity of the top cover. The water inlet pump 800 is connected with a water supply pipe and a water inlet pipe. The water supply pipe is used for connecting to an external water source, and the water inlet pipe is connected to the washing inner cavity.

[0067] During washing, the water inlet pump 800 is turned on, and the washing water input through the water supply pipe is transported from the water inlet pipe to the washing cavity. Under the action of the cleaning impeller 450, the washing water enters the water passage 602 and is sprayed out from the spray arm 610.

[0068] In other embodiments, in order to improve the cleaning effect, the present application further provides a water heating element in the installation cavity of the support base 300, and a bottom installation port 163 is provided on the washing bottom wall 160.
