[0053] An embodiment of the present application provides a dry-wet paper machine, as shown in the figure, the dry-wet paper machine comprises: Figures 1-10

[0054] a shell 4, the shell 4 includes a shell body 41 and a cover body 42, the cover body 42 is rotatably arranged on the shell body 41, and a storage space for storing paper towels is formed between the shell body 41 and the cover body 42; ​

[0055] a water tank 5 arranged on the casing 41;

[0056] a water pump 3 arranged on the casing 41;

[0057] a water spraying mechanism 2 comprising a water spraying seat 21 provided with a water spraying hole 214, the water spraying seat 21 being arranged on the casing 41;

[0058] a heating mechanism 1 comprising a heating container 11 and an electric heating element 12, the heating container 11 being formed with a heating cavity configured to temporarily store water to be heated, the heating container 11 being provided with a water inlet connecting portion 101 and a water outlet connecting portion 102, the water inlet connecting portion 101 and the water outlet connecting portion 102 respectively communicating with the heating cavity, the electric heating element 12 being configured to heat water in the heating container 11;

[0059] the water tank 5, the water pump 3, the heating container 11 and the water spraying seat 21 are sequentially connected;

[0060] the heating container 11 is arranged on the casing 41 and is obliquely arranged, the water inlet connecting portion 101 being lower than the water outlet connecting portion 102.

[0061] Specifically, the heating container 11 is installed on the casing 41 in an oblique posture, one end of the heating container 11 being higher and the other end being lower, and the water outlet connecting portion 102 is higher than the water inlet connecting portion 101 in the height direction. Water in the water tank 5 is transported into the heating container 11 through the water inlet connecting portion 101 by the water pump 3, and the water level in the heating container 11 gradually rises during the filling process, and under the action of the injected water, the air in the heating container 11 is discharged to the outside of the heating container 11 (from the water spraying hole 214) through the water outlet connecting portion 102.

[0062] During the water filling process of the heating container 11, since the heating container 11 is obliquely arranged and the water outlet connecting portion 102 is located at the high position of the heating container 11, the gas in the heating container 11 is completely and effectively discharged from the water outlet connecting portion 102 at the top.

[0063] In this way, the heating container 11 can be filled with water and the air can be completely discharged, so as to avoid the situation that the water supply is not smooth and the water spraying amount is not accurate during the water spraying process through the water spraying hole 214 due to the residual air in the heating container 11.

[0064] Further, the heating container 11 comprises a heating cylinder 111, a first cylinder cover 112 and a second cylinder cover 113, the heating cylinder 111 is connected between the first cylinder cover 112 and the second cylinder cover 113, and a heating cavity is formed between the heating cylinder 111, the first cylinder cover 112 and the second cylinder cover 113;

[0065] The heating cylinder 111 is further provided with an extension part adjacent to the end of the second cylinder cover 113, the extension part protrudes from the outer wall of the heating cylinder 111 and extends upward, and the water outlet connecting part 102 is arranged on the extension part;

[0066] The first cylinder cover 112 is provided with the water inlet connecting part 101.

[0067] Specifically, the heating container 11 adopts a split structure to facilitate assembly, and the heating cylinder 111 is between the first cylinder cover 112 and the second cylinder cover 113.

[0068] In order to facilitate the connection of the waterway, the water inlet connecting part 101 can be arranged on the first cylinder cover 112. The first cylinder cover 112 can be connected with the water pump 3 through the water inlet connecting part 101 to meet the requirement of conveying water into the heating container 11. The water inlet connecting part 101 can be a water inlet connector or the like, which is not limited here.

[0069] In addition, in order to meet the requirement of the heating container 11 to output heated water outward, the heating cylinder 111 is further provided with an extension part 117 adjacent to the end of the second cylinder cover 113, and the extension part 117 protrudes from the outer wall of the heating cylinder 111;

[0070] The water outlet connecting part 102 is arranged on the extension part 117.

[0071] Specifically, the extension part 117 of the heating cylinder 111 forms the water outlet connecting part 102, and the water outlet connecting part 102 can meet the requirement of outputting water in the heating cavity outward.

[0072] The extension part 117 is further provided with a connecting water groove 119, and the connecting water groove 119 communicates the water outlet connecting part 102 and the heating cavity.

[0073] The second cylinder cover 113 further covers the outside of the connecting water groove 119.

[0074] Specifically, in order for the water in the heating cylinder 111 to be heated and then flow to the outlet connection 102 for output, a connecting water tank 119 can be provided between the outlet connection 102 and the port of the heating cylinder 111. In this way, the water in the heating cylinder 111 flows to the outlet connection 102 through the connecting water tank 119. For example, the outlet connection 102 can be a through hole 118, and the connecting water tank 119 connects the through hole 118 to the port of the heating cylinder 111.

[0075] In addition, in order to keep the heating container 11 warm, the heating container 11 is wrapped with an insulation layer 15.

[0076] like Figure 9 As shown, the first end face of the housing 41 is provided with a first insertion port 416, and the heating container 11 is inserted into the housing 41 at an angle through the first insertion port 416;

[0077] A detachable first inspection cover plate 414 is also provided on the first end face of the housing 41. The first inspection cover plate 414 is arranged on the outside of the heating container 11 and covers the first insertion port 416.

[0078] Specifically, in order to facilitate the maintenance and replacement of the heating mechanism 1 in the future, a first insertion port 416 can be provided on the housing 41. The heating container 11 in the heating mechanism 1 can be inserted into the housing 41 at an angle through the first insertion port 416, and then the outside is covered and protected by the first inspection cover plate 414.

[0079] Furthermore, the heating container 11 is provided with a fixed lifting lug 110, which is arranged at an angle relative to the heating container 11.

[0080] Specifically, after the heating container 11 is assembled into the housing 41 via the first insertion port 416, the heating container 11 needs to be fixed. This is done by setting a fixing lug 110 on the heating container 11, which can be fixedly connected to the housing 41 by screws.

[0081] Furthermore, since the fixed lug 110 is arranged at an angle relative to the heating container 11, the heating container 11 can be installed at an angle in the housing 41.

[0082] In order to ensure that the water outlet connection 102 is higher than the water inlet connection 101, when the fixed lug 110 is arranged close to the water outlet connection 102, the heating container 11 extends downward from the fixed lug 110. Alternatively, when the fixed lug 110 is arranged close to the water inlet connection 101, the heating container 11 extends upward from the fixed lug 110.

[0083] Further, a second insertion port 417 is arranged on the second end surface of the shell 41, and the water tank 5 is inserted into the shell 41 via the second insertion port 417.

[0084] Specifically, in order to meet the requirement of disassembling the water tank 5, a second insertion port 417 can also be arranged on the shell 41, and the water tank 5 can be inserted into the shell 41 via the second insertion port 417.

[0085] Further, a second removable inspection cover plate 415 is arranged on the second end surface of the shell 41, and an electrical appliance chamber is formed between the second inspection cover plate 415 and the second end surface of the shell 41, and an electric control panel 6 is arranged in the electrical appliance chamber, and the electric control panel 6 is electrically connected with the water pump 3.

[0086] Specifically, in order to facilitate the assembly of the electric control panel 6, an electrical appliance chamber is formed between the shell 41 and the second inspection cover plate 415 to meet the installation requirement of the electric control panel 6.

[0087] Similarly, a third insertion port 418 is arranged on the second inspection cover plate 415, and the water tank 5 is inserted into the shell 41 via the third insertion port 418 and the second insertion port 417.

[0088] In another embodiment of the present application, as shown in Figure 10 In order to prevent the cover 42 from automatically turning over due to gravity after being opened, the following structural improvements are made to the shell 4.

[0089] The shell 41, in which a storage groove is formed, and rotating support portions 403 are arranged on both sides of the storage groove on the shell 41, and a first positioning protrusion 404 is arranged on the outside of at least one of the rotating support portions 403 on the shell 41;

[0090] The cover 42, rotating connection portions 421 are arranged on both sides of the cover 42, and a second positioning protrusion 422 is arranged on the outside of at least one of the rotating connection portions 421 on the cover 42;

[0091] The rotating connection portions 421 are rotatably arranged on the rotating support portions 403;

[0092] In addition, the first positioning protrusion 404 and the second positioning protrusion 422 are configured such that, after the cover 42 is turned open, the second positioning protrusion 422 abuts against the first positioning protrusion 404 to support the cover 42.

[0093] Specifically, in actual use, when the paper in the storage groove in the shell 4 is used up, the user needs to open the cover 42 to replace the new paper. During the process of opening the cover 42, the second positioning protrusion 422 will gradually approach the first positioning protrusion 404, and as the cover 42 continues to rotate and open, the second positioning protrusion 422 extrudes and passes over the first positioning protrusion 404, so that when the cover 42 is flipped and closed under the action of gravity, the first positioning protrusion 404 and the second positioning protrusion 422 can cooperate to block the cover 42 from falling back.

[0094] During the replacement of the paper, the cooperation of the first positioning protrusion 404 and the second positioning protrusion 422 can block the cover 42 from falling back, thereby improving the convenience of the user during the replacement of the paper.

[0095] Among them, for the first positioning protrusion 404, a corresponding first positioning protrusion 404 can be configured for each rotating support part 403, and correspondingly, on the cover 42, a corresponding second positioning protrusion 422 is configured for each rotating connecting part 421.

[0096] By arranging the rotating support part 403 on the shell 41 on both sides of the storage groove, the rotating support part 403 cooperates with the rotating connecting part 421 on the cover 42 to meet the rotation requirement of the cover 42, and at the same time, the first positioning protrusion 404 is arranged on the shell 41 outside the rotating support part 403, and correspondingly, the second positioning protrusion 422 is arranged on the cover 42 outside the rotating connecting part 421. In use, after the cover 42 is opened, the second positioning protrusion 422 passes over the first positioning protrusion 404, and the second positioning protrusion 422 abuts against the first positioning protrusion 404, thereby blocking the cover 42 from automatically flipping under the action of gravity, so as to improve the use reliability of the user.

[0097] Further, the cover 42 is further provided with a first guide sliding groove 423, the first guide sliding groove 423 is a circular arc structure, and the first guide sliding groove 423 surrounds the periphery of the rotating connecting part 421.

[0098] The first positioning protrusion 404 is slidably arranged in the first guide sliding groove 423, and the second positioning protrusion 422 is located in the first guide sliding groove 423.

[0099] Specifically, the first guide sliding groove 423 can cooperate with the first positioning protrusion 404 to guide the rotation of the cover 42 relative to the shell 41. The second positioning protrusion 422 is located in the first guide sliding groove 423, and then after the cover 42 is opened, the first positioning protrusion 404 supports the second positioning protrusion 422 in the first guide sliding groove 423 to maintain the cover 42 in the opened state.

[0100] Similarly, a second guide chute can also be arranged on the shell 41, the second guide chute is in a circular arc structure, and the second guide chute surrounds the periphery of the rotating support part 403; the second positioning protrusion 422 is slidably arranged in the second guide chute, and the first positioning protrusion 404 is located in the second guide chute.

[0101] Further, in order to realize the cooperation of the rotating connecting part 421 and the rotating support part 403 to meet the requirement of the rotation of the cover body 42, the rotating connecting part 421 is in a shaft structure, and the rotating support part 403 is in a hole structure; or the rotating connecting part 421 is in a hole structure, and the rotating support part 403 is in a shaft structure.

[0102] In another embodiment of the present application, as shown in Figure 4 The shell 41 is formed with a mounting space, and the water tank 5, the water pump 3 and the heating container 11 are arranged in the mounting space.

[0103] Specifically, the shell 41 can be formed with a mounting space to meet the mounting requirements of the water tank 5, the water pump 3 and the heating container 11.

[0104] In order to realize the separation of space to install different components, the mounting space includes a first mounting channel 401 and a second mounting channel 402.

[0105] The first mounting channel 401 is used to independently install the water tank 5, thereby meeting the use requirement that the water tank 5 needs to be disassembled and refilled during use, and the second mounting channel 402 is used to install the water pump 3 and the heating container 11. In this way, the water tank 5 which needs to be frequently disassembled and assembled can be independently installed, so as to avoid the influence of the frequent disassembly and assembly of the water tank 5 on the fixed heating container 11 and the water pump 3, thereby improving the use reliability.

[0106] In order to reduce the overall processing difficulty of the shell 41 and make it more convenient for the operator to assemble the related components to the shell 41, the structure of the shell 41 is improved as follows.

[0142] Specifically, for the heating container 11, a heating cavity is formed in the inside, and the water in the heating cavity can be heated under the action of the electric heating element 12, thereby meeting the use requirements.

[0143] In the state of not being used, the water in the heating container 11 is in a static state, and with the extension of time, the water in the heating container 11 is easy to breed bacteria. By arranging the first sterilization irradiation port on the heating container 11 and sealing and shielding the first sterilization irradiation port by the first quartz plate 13, ultraviolet rays generated by the first ultraviolet LED lamp 14 arranged outside the first quartz plate 13 can be irradiated into the heating container 11, and the water stored in the heating container 11 is sterilized, thereby reducing the continuous breeding of bacteria in the heating container 11.

[0144] Further, the heating container 11 comprises a heating cylinder 111, a first end cover 112 and a second end cover 113, the heating cylinder 111 is connected between the first end cover 112 and the second end cover 113, and the heating cavity is formed between the heating cylinder 111, the first end cover 112 and the second end cover 113;

[0158] In an embodiment of the application, for the water spraying mechanism 2, bacteria are easy to breed in the water in the water spraying mechanism 2 in the standby state after the water spraying operation is completed. In order to solve the problem of bacteria breeding in the water in the water spraying mechanism 2, the water spraying mechanism 2 is improved and designed as follows.

[0159] As shown in Figures 17-19 The water spraying mechanism 2 provided by the embodiment comprises:

[0160] A water spraying seat 21 in a strip structure, a water supply channel 211 and a plurality of water outlet channels 212 are arranged in the water spraying seat 21, an installation socket 213 communicating with the water supply channel 211 is arranged at the end of the water spraying seat 21, a plurality of water spraying holes 214 are arranged on the front side of the water spraying seat 21, the water spraying holes 214 communicate with the corresponding water outlet channels 212, and the plurality of water outlet channels 212 respectively communicate with the water supply channel 211;

[0161] A connecting pipe 22, a plurality of connecting holes 221 are arranged on the pipe wall of the connecting pipe 22, the connecting pipe 22 is sealingly inserted into the installation socket 213 and extends into the water supply channel 211, and the connecting holes 221 communicate with the corresponding water outlet channels 212;

[0162] A second ultraviolet LED lamp 23 is arranged at the end of the connecting pipe 22 and configured to irradiate ultraviolet light into the connecting pipe 22.

[0163] Specifically, the connecting pipe 22 is inserted into the water supply channel 211 of the water spraying seat 21, and the connecting pipe 22 can be used to transport water. After the water in the connecting pipe 22 is transported into the water spraying seat 21, the water in the connecting pipe 22 flows into the corresponding water outlet channel 212 through the connecting hole 221 to meet the requirement of water outlet.

[0164] In the state of not being used, the water in the connecting pipe 22 is in a static state, and with the extension of time, the water in the connecting pipe 22 is prone to bacterial growth. By arranging the second ultraviolet LED lamp 23 at the end of the connecting pipe 22, the second ultraviolet LED lamp 23 generates ultraviolet light irradiation into the connecting pipe 22, and the water stored in the connecting pipe 22 is subjected to sterilization treatment by the ultraviolet light, thereby reducing the continuous growth of bacteria in the connecting pipe 22.

[0165] The pipe diameter of the connecting pipe 22 is larger than that of the water outlet channel 212, so the water storage capacity in the connecting pipe 22 will be much larger than that of the water outlet channel 212. In the case of effectively inhibiting the growth of bacteria in the connecting pipe 22, the overall bacterial number can be effectively inhibited.

[0166] Preferably, the outer wall of the connecting pipe 22 is further provided with a light reflecting layer, which is configured to reflect ultraviolet light towards the connecting hole 221.

[0169] Specifically, since the connecting hole 221 arranged on the connecting pipe 22 needs to communicate with the corresponding water outlet channel 212, after the connecting pipe 22 is inserted into the water inlet channel, the connecting hole 221 of the connecting pipe 22 needs to be adjusted to be aligned with the water outlet channel 212. In order to improve the assembly convenience, by positioning the positioning portion 222 and the positioning matching portion, the installation posture of the connecting pipe 22 can be positioned so that the connecting hole 221 can be aligned with the water outlet channel 212.

[0172] Specifically, the water output from the water spraying hole 214 can be treated by the spray head 25 to achieve a spraying effect. The specific structure of the spray head 25 can adopt the structure of a conventional spray head, which is not limited and described here.

[0173] Further, for the second ultraviolet LED lamp 23, it can be installed at any end of the connecting pipe 22. For example, the second ultraviolet LED lamp 23 is arranged outside the water spraying seat 21, and the second ultraviolet LED lamp 23 is located outside the outer pipe opening of the connecting pipe 22.

[0174] Alternatively, the water spraying seat 21 is provided with a second sterilization irradiation opening, which is arranged at the end of the water supply channel 211, and the second sterilization irradiation opening is in communication with the water supply channel 211. The second sterilization irradiation opening is sealingly provided with a second quartz plate 24; the second ultraviolet LED lamp 23 is arranged outside the second quartz plate 24, and the second ultraviolet LED lamp 23 is located outside the inner pipe opening of the connecting pipe 22.

[0175] Based on the water spraying mechanism 2 in the above embodiment, the dry and wet paper machine provided by the application directly or indirectly connects the water spraying mechanism 2 and the water pump 3 to realize sterilization and water spraying.

[0176] By arranging the connecting pipe 22 in the water supply channel 211 of the water spraying seat 21, the connecting pipe 22 is used to meet the requirement of supplying water to the water spraying hole 214, and the end of the connecting pipe 22 is further provided with the second ultraviolet LED lamp 23. The second ultraviolet LED lamp 23 irradiates ultraviolet rays into the connecting pipe 22, so that in actual use, the water in the connecting pipe 22 can be reduced by the ultraviolet irradiation of the second ultraviolet LED lamp 23. Bacteria are generated, thereby improving the user safety and experience.

Ultraviolet rays are used to sterilize the stored water, thereby reducing the continuous breeding of bacteria in the stored water.

[0190] The second ultraviolet LED lamp 23 is arranged at the through hole 118 and is configured to irradiate ultraviolet rays into the connecting pipe 22 through the first quartz plate 13 and the through hole 118.
