[0070] Specifically, the distance between the second pair of photoelectric switches 42 and the water spraying hole 214 in the height is within the range of 20 mm, so that after the paper towel is detected, the water spraying mechanism 2 can timely spray water to increase the coverage area of the wet paper towel.

[0071] Further, a plurality of mounting ribs 407 are arranged in the mounting clamping groove 405, and the mounting ribs abut against the water spraying seat 21.

[0072] Specifically, in order to conveniently support and install the water spraying seat 21, the mounting ribs 407 can be arranged in the mounting clamping groove 405 to support and install the water spraying seat 21 through the mounting ribs 407.

[0073] The water spraying seat is provided with a positioning protrusion 216, and the positioning protrusion 216 protrudes from the water spraying seat 21.

[0074] The positioning protrusion 216 is located between two adjacent mounting ribs 407.

[0078] The limiting column 445 is clamped in the limiting clamping groove 425, the screw passes through the through hole and is screwed on the screw fixing seat 426, the second pair of photoelectric switches 442 are arranged on the water spraying seat 21 and located in the mounting clamping groove 405, and the waterproof cover 443 covers the outer side of the second pair of photoelectric switches 442.

[0079] When the cover 42 is in a closed state, the first pair of photoelectric switches 441 and the second pair of photoelectric switches 442 are oppositely arranged.

[0080] Specifically, in order to detect the position of the paper towel, so that the paper towel is detected during output to trigger the water spraying mechanism 2 to spray water on the output paper towel, a photoelectric detection assembly can be installed on the shell 41 and the cover 42, wherein the first pair of photoelectric switches 441 in the photoelectric detection assembly are fixedly installed on the cover 42 through the waterproof cover 443, and the second pair of photoelectric switches 442 are arranged on the water spraying seat 21 to be assembled to the shell 41 by means of the water spraying seat 21.

[0081] After the first pair of photoelectric switches 441 are fixedly installed on the inner wall of the waterproof cover 443 by means of the screw, the waterproof cover 443 is first clamped in the limiting clamping groove 425 by means of the limiting column 445, and then the waterproof cover 443 is fixed on the cover by means of the screw. In this way, the use of the screw can be reduced to improve the assembly efficiency.

[0082] The first pair of photoelectric switches 441 are fixedly installed on the water spraying seat 21 by means of the screw, so that the water spraying seat 21 can be installed and fixed in the smaller mounting clamping groove 405, which is more conducive to improving the assembly efficiency.

[0083] The waterproof cover 443 and the waterproof cover plate 444 can play a waterproof function to ensure that the influence of splashing water on the first pair of photoelectric switches 441 and the second pair of photoelectric switches 442 is reduced during the process that the water spraying seat 21 sprays water on the output paper towel.

[0084] Based on the above technical scheme, optionally, the dry and wet paper machine further comprises a heating mechanism 1, the heating mechanism 1 comprises a heating container 11 and an electric heating element 12, the heating container 11 is formed with a heating cavity inside, the heating cavity is configured to temporarily store water to be heated, the heating container 11 is provided with a water inlet connecting part 101 and a water outlet connecting part 102, the water inlet connecting part 101 and the water outlet connecting part 102 respectively communicate with the heating cavity, and the electric heating element 12 is configured to heat the water in the heating container 11.

[0085] The water tank 5, the water pump 3, the heating container 11 and the water spraying seat 21 are connected in sequence.

[0086] The heating container 11 is arranged on the shell 41 and is arranged obliquely, and the water inlet connecting part 101 is lower than the water outlet connecting part 102.

[0087] Specifically, the heating container 11 is installed on the shell 41 in an inclined posture, one end of the heating container 11 is high and the other end is low, and the water outlet connecting part 102 is higher than the water inlet connecting part 101 in the height direction. The water in the water tank 5 is transported into the heating container 11 through the water inlet connecting part 101 by the water pump 3, and the water level in the heating container 11 gradually rises during the filling process. 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 part 102.

[0088] During the water filling process of the heating container 11, since the heating container 11 is arranged obliquely and the water outlet connecting part 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 part 102 at the top.

[0089] In this way, the heating container 11 can be filled with water and the air can be 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 of the water pump 3 through the water spraying hole 214 due to the residual air in the heating container 11.

[0090] 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.

[0096] The extension 117 is provided with the water outlet connection 102.

[0097] Specifically, the extension 117 of the heating cylinder 111 forms a water outlet connection 102, which can meet the requirement of water being output from the heating chamber.

[0098] The extension 117 is also provided with a connecting water tank 119, which connects the water outlet connection 102 and the heating cavity.

[0099] The second cylindrical cover 113 also covers the outside of the connecting water tank 119.

[0100] 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.

[0101] In addition, in order to keep the heating container 11 warm, the heating container 11 is wrapped with an insulation layer 15.

[0106] Specifically, after the heating container 11 is assembled into the shell 41 through the first insertion port 416, the heating container 11 needs to be fixed. By providing a fixed lug 110 on the heating container 11, the fixed lug 110 can be fixedly connected to the shell 41 by screws.

[0107] And, since the fixed lug 110 is arranged obliquely relative to the heating container 11, the heating container 11 can be obliquely installed in the shell 41.

[0108] In order to ensure that the water outlet connection part 102 is higher than the water inlet connection part 101. In the case where the fixed lug 110 is arranged close to the water outlet connection part 102; the heating container 11 is obliquely extended downward by the fixed lug 110. Or, in the case where the fixed lug 110 is arranged close to the water inlet connection part 101, the heating container 11 is obliquely extended upward by the fixed lug 110.

[0109] Further, the second end surface of the shell 41 is provided with a second insertion port 417, and the water tank 5 is obliquely inserted into the shell 41 through the second insertion port 417.

[0110] Specifically, in order to meet the requirements of disassembling the water tank 5, a second insertion port 417 can also be provided on the shell 41, and the water tank 5 can be inserted into the shell 41 through the second insertion port 417.

[0111] Further, the second end surface of the shell 41 is further provided with a detachable second access cover plate 415, and an electrical appliance room is formed between the second access cover plate 415 and the second end surface of the shell 41. An electric control panel 6 is arranged in the electrical appliance room, and the electric control panel 6 is electrically connected with the water pump 3.

[0112] Specifically, in order to facilitate the assembly of the electric control panel 6, an electric appliance chamber can be formed between the shell 41 and the second access cover plate 415 to meet the installation requirements of the electric control panel 6.

[0113] Similarly, the second access cover plate 415 is also provided with a third insertion opening 418, and the water tank 5 is inserted into the shell 41 through the third insertion opening 418 and the second insertion opening 417 in sequence.

[0114] 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.

[0115] The shell 41 is provided with a storage groove, and rotating support portions 403 are arranged on both sides of the storage groove.

[0116] The cover 42 is provided with rotating connection portions 421 on both sides, and second positioning protrusions 422 are arranged on the outer sides of at least one of the rotating connection portions 421.

[0117] The rotating connection portions 421 are rotatably arranged on the rotating support portions 403.

[0119] Specifically, during actual use, when the paper towels placed in the storage groove in the shell 4 are used up, the user needs to open the cover 42 to replace new paper towels. During the process of opening the cover 42, the second positioning protrusions 422 will gradually approach the first positioning protrusions 404. As the cover 42 continues to be turned open, the second positioning protrusions 422 press and pass the first positioning protrusions 404. In this way, when the cover 42 is turned closed under the action of gravity, the first positioning protrusions 404 and the second positioning protrusions 422 can cooperate to block the cover 42 from falling back.

[0155] In one embodiment of this application, for the heating mechanism, since bacteria can easily grow in the water inside the heating mechanism when it is in standby state after heating is completed, the heating mechanism is improved as follows to solve the problem of bacteria growing in the water inside the heating mechanism.

[0156] like Figures 13-16 As shown, this embodiment provides a heating mechanism 1, including:

[0157] A heating container 11 has a heating cavity formed inside it. The heating cavity is configured to temporarily store water to be heated. The heating container 11 is provided with an inlet connection and an outlet connection, which are respectively connected to the heating cavity.

[0158] An electric heating element 12 is disposed on the heating container 11 and configured to heat the water in the heating container 11;

[0159] The heating container 11 is further provided with a first sterilization irradiation port, and a first quartz plate 13 is sealed and covered on the first sterilization irradiation port. A first ultraviolet LED lamp 14 is provided outside the first quartz plate 13. The first ultraviolet LED lamp 14 is configured to irradiate ultraviolet light into the heating container 11 through the first quartz plate 13.

[0160] Specifically, for the heating container 11, a heating cavity is formed inside. The water in the heating cavity can be heated by the electric heating element 12 to meet the requirements of use.

[0161] 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 providing the first sterilization irradiation port on the heating container 11, and by sealing and shielding the first sterilization irradiation port by the first quartz plate 13, the ultraviolet rays generated by the first ultraviolet LED lamp 14 arranged outside the first quartz plate 13 can irradiate into the heating container 11, and the water stored in the heating container 11 is sterilized by the ultraviolet rays, thereby reducing the continuous breeding of bacteria in the heating container 11.

[0162] 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 a heating cavity is formed between the heating cylinder 111, the first end cover 112 and the second end cover 113.

[0165] The first quartz plate 13 is sealed at the port of the heating cylinder 111, and the first ultraviolet LED lamp 14 is installed between the first quartz plate 13 and the second end cover 113, so that the first ultraviolet LED lamp 14 can be conveniently built-in in the heating container 11 to facilitate assembly.

[0166] Further, a stepped surface 114 is formed in the first sterilization irradiation port, the first quartz plate 13 abuts against the stepped surface 114, a sealing ring is arranged between the first quartz plate 13 and the stepped surface 114, and the second end cover 113 abuts against the first quartz plate 13 and presses the first quartz plate 13 tightly on the sealing ring.

[0167] Specifically, in order to improve the installation sealing property of the first quartz plate 13, the stepped surface 114 is formed at the port of the heating cylinder 111 to press the sealing ring between the first quartz plate 13 and the stepped surface 114, and the sealing ring can effectively enhance the connection sealing property between the first quartz plate 13 and the stepped surface 114.

[0169] Specifically, the annular rib 115 formed on the second end cover 113 can exert sufficient pressure on the first quartz plate 13 to ensure that the first quartz plate 13 presses the sealing ring against the stepped surface 114. Meanwhile, the annular rib 115 surrounding the mounting area can also preinstall the first ultraviolet LED lamp 14.

[0170] The through hole 118, the connecting water tank 119 and the port of the heating cylinder 111 are sealed by the first quartz plate 13.

[0171] Further, the heating cylinder 111 is made of a heat-conducting material, and the outer wall of the heating cylinder 111 is provided with a heat-conducting mounting surface 116, and the electric heating element 12 is arranged on the heat-conducting mounting surface 116.

[0172] Specifically, the heating cylinder 111 is made of a heat-conducting material, for example, a conventional heat-conducting material such as stainless steel or aluminum. The outer surface of the heating cylinder 111 is formed with a heat-conducting mounting surface 116, which is a plane. In this way, the heat-conducting connection area between the electric heating element 12 and the heating cylinder 111 can be effectively increased to improve the heating efficiency.

[0173] The electric heating element 12 can be a conventional electric heating element such as a PTC heating sheet or an electric heating plate.

[0174] Based on the heating mechanism 1 in the above embodiment, the dry and wet paper machine provided in the application connects the above heating mechanism 1 between the water spraying mechanism 2 and the water pump 3.

[0175] The first sterilization irradiation port is sealed and covered by the first quartz plate 13, and the first ultraviolet LED lamp 14 is arranged outside the first quartz plate 13. The first ultraviolet LED lamp 14 irradiates ultraviolet rays into the heating container 11. In actual use, the water in the heating container 11 is irradiated by the ultraviolet rays generated by the first ultraviolet LED lamp 14, which can reduce the generation of bacteria, thereby improving the safety and experience of users.

[0176] In an embodiment of the application, for the water spraying mechanism 2, bacteria are easy to breed in the water inside 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 inside the water spraying mechanism 2, the water spraying mechanism 2 is improved and designed as follows.

[0177] As Figures 17-19As shown, the embodiment provides a water spraying mechanism 2, comprising:

[0178] A water spraying seat 21 in strip structure, provided with a water supply channel 211 and a plurality of water outlet channels 212, the end of the water spraying seat 21 is provided with a mounting socket 213 communicating with the water supply channel 211, and a plurality of water spraying holes 214 are further provided on the front side of the water spraying seat 21, which communicate with the corresponding water outlet channels 212, and the plurality of water outlet channels 212 respectively communicate with the water supply channel 211;

[0179] A connecting pipe 22, provided with a plurality of connecting holes 221 on the pipe wall, the connecting pipe 22 is sealingly inserted into the mounting socket 213 and extends into the water supply channel 211, and the connecting holes 221 communicate with the corresponding water outlet channels 212;

[0180] A second ultraviolet LED lamp 23, provided at the end of the connecting pipe 22 and configured to irradiate ultraviolet light towards the connecting pipe 22.

[0181] Specifically, the connecting pipe 22 is inserted into the water supply channel 211 of the water spraying seat 21, which can be used to transport water, and 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.

[0182] 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 easy to breed bacteria. By providing the second ultraviolet LED lamp 23 at the end of the connecting pipe 22, the second ultraviolet LED lamp 23 generates ultraviolet light irradiating into the connecting pipe 22, and the stored water in the connecting pipe 22 is sterilized by the ultraviolet light, thereby reducing the continuous breeding of bacteria in the connecting pipe 22.

[0183] 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, and in the case of effectively inhibiting the breeding of bacteria in the connecting pipe 22, the overall number of bacteria can be effectively inhibited.

[0184] 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.

[0185] Specifically, the light reflecting layer provided on the connecting pipe 22 can emit ultraviolet light into the water outlet channel 212, thereby further inhibiting the breeding of bacteria in the water outlet channel 212 to a certain extent.

[0186] Further, the connecting pipe 22 is provided with a positioning portion 222, and the water spraying seat 21 is provided with a positioning matching portion; the positioning portion 222 and the positioning matching portion are connected together.

[0187] Specifically, since the connecting hole 221 arranged on the connecting pipe 22 needs to be communicated with the corresponding water outlet flow channel 212, therefore, after the connecting pipe 22 is inserted into the water inlet flow channel, the connecting hole 221 of the connecting pipe 22 needs to be adjusted to be aligned with the water outlet flow channel 212. In order to improve the assembly convenience, the installation posture of the connecting pipe 22 can be positioned through the mutual positioning and matching of the positioning portion 222 and the positioning matching portion, so that the connecting hole 221 can be aligned with the water outlet flow channel 212.

[0189] In addition, in order to improve the effect of water spraying, the water spraying mechanism 2 further comprises a spray head 25, which is detachably arranged on the water spraying seat 21 and covers the water spraying hole 214.

[0190] Specifically, the water output from the water spraying hole 214 can be treated through the spray head 25 to achieve the effect of spraying. The specific structure of the spray head 25 can adopt the structure of a conventional spray head, which is not limited and described here.

[0191] 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.

[0193] Based on the water spraying mechanism 2 in the above embodiments, 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 water spraying.

[0194] By arranging the connecting pipe 22 in the water supply flow 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 is arranged to irradiate ultraviolet rays into the connecting pipe 22. In actual use, the water in the connecting pipe 22 is affected by the irradiation of the ultraviolet rays generated by the second ultraviolet LED lamp 23, so that the generation of bacteria can be reduced, and the safety and experience of users are improved.

[0195] In the embodiments one and two, the internal water storage in the heating mechanism 1 and the water spraying mechanism 2 is prone to bacterial growth. Therefore, the heating mechanism 1 and the water spraying mechanism 2 are simultaneously improved and designed.

The end of the water spraying seat 21 is provided with a mounting socket 213 which communicates with the water supply flow channel 211. The front side of the water spraying seat 21 is further provided with a plurality of water spraying holes 214 which communicate with the corresponding water outlet flow channels 212. The connecting pipe 22 is provided with a plurality of connecting holes 221 on the pipe wall. The connecting pipe 22 is sealingly inserted into the mounting socket 213 and extends into the water supply flow channel 211. The connecting holes 221 communicate with the corresponding water outlet flow channels 212. The second ultraviolet LED lamp 23 is arranged at the end of the connecting pipe 22 and is configured to irradiate ultraviolet rays into the connecting pipe 22;

[0200] The water pump 3, the heating container 11 and the connecting pipe 22 are sequentially connected.

[0201] Specifically, the heating container 11 in the heating mechanism 1 can be irradiated by the first ultraviolet LED lamp 14 to achieve sterilization and bacteriostasis treatment during use. Similarly, the connecting pipe 22 in the water spraying mechanism 2 can be irradiated by the second ultraviolet LED lamp 23 to achieve sterilization and bacteriostasis treatment. The use of ultraviolet light for sterilization of stored water can further reduce the continuous growth of bacteria in the stored water.

[0202] 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 a heating cavity is formed between the heating cylinder 111, the first end cover 112 and the second end cover 113.

[0203] The heating cylinder 111 is further provided with an extension 117 adjacent to the end of the second end cover 113, and the extension 117 protrudes from the outer wall of the heating cylinder 111;

[0204] The extension 117 is provided with a through hole 118, and the surface of the extension 117 opposite to the second end cover 113 is further provided with a connecting water groove 119, and the connecting water groove 119 is connected between the through hole 118 and the port of the heating cylinder 111;

[0205] The first quartz plate 13 is clamped between the heating cylinder 111 and the second end cover 113, and the first quartz plate 13 further seals and covers the through hole 118 and the connecting water groove 119;

[0206] The connecting pipe 22 is sealingly inserted into the through hole 118, and the connecting pipe 22 communicates with the heating cavity through the connecting water groove 119; the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are arranged between the first quartz plate 13 and the second end cover 113;

[0207] The first ultraviolet LED lamp 14 is arranged at the port of the heating cylinder 111 and is configured to irradiate ultraviolet light into the heating cylinder 111 through the first quartz plate 13;

[0208] The second ultraviolet LED lamp 23 is arranged at the through hole 118 and is configured to irradiate ultraviolet light into the connecting pipe 22 through the first quartz plate 13 and the through hole 118.

[0209] Specifically, since the water output by the heating mechanism 1 is transported into the water spraying seat 21 through the connecting pipe 22 and sprayed out from the water spraying hole 214, in order to facilitate the centralized installation of the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23, the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 can be installed on the second end cover 113 of the heating container 11.

[0210] Since the end of the connecting pipe 22 is inserted into the through hole 118 of the extension 117, the through hole 118 is further sealed and covered by the first quartz plate 13. In this way, the second ultraviolet LED lamp 23 can irradiate ultraviolet rays through the first quartz plate 13 and into the connecting pipe 22 through the through hole 118.

[0211] Since the first ultraviolet LED lamp 14 and the second ultraviolet LED lamp 23 are installed between the second end cover 113 and the first quartz plate 13, on the one hand, it is convenient for centralized assembly, and on the other hand, it is also convenient for the second ultraviolet LED lamp 23 to irradiate the inside of the connecting pipe 22 from the end of the connecting pipe 22.

[0212] Further, the pipe body of the connecting pipe 22 exposed between the water spraying seat 21 and the extension 117 is further provided with a protective pipe 26, which is wrapped outside the connecting pipe 22 and located between the water spraying seat 21 and the extension 117.

[0213] Specifically, since the connecting pipe 22 needs to be irradiated with ultraviolet rays, and part of the connecting pipe 22 will protrude outside the water spraying seat 21 and the corresponding port of the connecting pipe 22 will be inserted into the through hole 118. By wrapping the protective pipe 26 outside the connecting pipe 22, on the one hand, it can protect the connecting pipe 22, and on the other hand, it can reduce the ultraviolet rays from the outside of the connecting pipe 22, so as to improve the sterilization intensity of the ultraviolet rays in the connecting pipe 22.
