Description

Technical Field

[0001] This utility model relates to the technical field of bidets, and in particular to a bidet with an external filter. Background Technology

[0002] A bidet is a water outlet device installed on the toilet to wash the buttocks. Due to differences in water quality and the problem of water pollution from long-term use, existing technologies have incorporated filters into bidets to remove impurities and improve water quality. These filters are typically installed between the water inlet pipe and the bidet's inlet, allowing filtered water to enter the bidet. However, this installation method is inconvenient because the water inlet pipe is located behind the toilet, resulting in limited operating space and making filter removal and replacement difficult. Utility Model Content

[0003] The purpose of this utility model is to provide a bidet with an external filter to solve the above-mentioned technical problems, making the filter on the bidet easy to install and remove, and convenient to operate.

[0004] To achieve the above objectives, the solution of this utility model is: a bidet with an external filter, comprising a filter body and a bidet body;

[0005] The filter body is provided with a filter inlet chamber and a filter outlet chamber. The filter body has a filter inlet that leads to the filter inlet chamber and a filter outlet that leads to the filter outlet chamber. Water flows into the filter inlet chamber from the filter inlet, enters the filter outlet chamber after filtration, and then flows out from the filter outlet.

[0006] The bidet body includes a housing with an inlet channel, an outlet channel, and a nozzle. The inlet channel is connected to an external water source, and the outlet channel is connected to the nozzle. The filter body is detachably installed on the housing so that when the filter body is installed on the housing, the inlet of the filter chamber is connected to the inlet channel, and the outlet of the filter chamber is connected to the outlet channel. Water flows through the outlet channel after being filtered by the filter body and is sprayed out from the nozzle.

[0007] Furthermore, the housing is provided with an installation port, which extends into the housing to form an installation channel. The water inlet channel and the water outlet channel extend into the installation channel. One end of the filter body is formed with a plug. The water inlet and water outlet of the filter chamber are formed on the plug, so that when the plug is inserted from the installation port and sealed in the installation channel, the water inlet of the filter chamber is connected to the water inlet channel, and the water outlet of the filter chamber is connected to the water outlet channel.

[0008] Furthermore, the end of the plug protrudes to form an outlet connector, and the filter chamber inlet surrounds the outer periphery of the outlet connector. When the plug is inserted from the installation port and sealed in the installation channel, the outlet connector is sealed in the inlet and outlet channels, so that the filter chamber outlet is connected to the inlet channel, and the inlet channel surrounds the outer periphery of the outlet channel and is connected to the filter chamber inlet.

[0009] Furthermore, it also includes a first water seal, which is installed between the outlet connector and the outlet channel.

[0010] Furthermore, it also includes a second water seal, which is installed between the connector and the installation channel.

[0011] Furthermore, the connector and the installation channel are snap-fitted together.

[0012] Furthermore, a groove is formed on the inner wall of the installation channel, and a locking block is protruded on the outer wall of the connector. An insertion port is formed on the groove for the locking block to be inserted. After the connector is inserted into the installation channel, the locking block aligns with the insertion port and rotates around the axis from the insertion port to lock into the groove, thereby restricting the locking block from sliding axially.

[0013] Furthermore, the bidet body is also equipped with a switching knob, which includes a knob and a switching valve. The knob is connected to one end of the switching valve so that when the switching knob is installed on the housing, the knob protrudes outside the housing. The switching valve is set on the water outlet channel. After the filter body is installed, the switching valve is connected in series between the filter body and the nozzle. Multiple nozzles are provided. The switching valve is used to guide the water flow filtered by the filter body to different nozzles for spraying.

[0014] Furthermore, the bidet body is detachably installed between the toilet seat and the seat ring assembly, with a knob extending outside the toilet seat and located on the side for hand operation, and a nozzle extending into the toilet seat for cleaning the buttocks.

[0015] Furthermore, the filter body consists of a connector and a main body. The connector protrudes from one side of the main body so that after the connector is inserted into the installation channel, the connector is located inside the installation channel, while the main body is located outside the installation channel.

[0016] Furthermore, it also includes a fixing component that is detachably installed on the bidet body. The fixing component has a limiting part formed on it. After the fixing component is installed on the bidet body, the limiting part abuts against the filter body, restricting the filter body from moving away from the installation channel.

[0017] Furthermore, the direction in which the connector of the filter body exits from the installation channel is perpendicular to the direction in which the fastener is removed from the bidet body.

[0018] Furthermore, an installation groove for installing the filter body is formed on the bidet body, and an installation channel is formed in the installation groove. The installation groove is exposed on the side wall of the bidet body. A fastener is used to block the installation groove to restrict the filter body from being removed from the installation groove. After the fastener blocks the installation groove, the fastener and the bidet body are combined to form a complete outer contour of the bidet.

[0019] Furthermore, a stop portion is formed in the mounting groove, which faces the mounting channel. After the filter body is installed in the mounting groove, the stop portion is spaced apart from the filter body to form an installation gap. When the fastener blocks the mounting groove, the limiting portion is embedded in the installation gap to abut against the filter body.

[0020] Furthermore, on the side of the limiting part facing the filter body, a first abutting surface and an inclined surface are formed sequentially from the fixing member to the mounting groove. The first abutting surface is perpendicular to the direction in which the plug exits from the mounting channel, and the inclined surface is inclined and recessed inward towards the mounting groove.

[0021] The limiting part forms a second abutting surface on the side away from the filter body. The second abutting surface is used to abut against the stop part. When the limiting part is inserted into the installation gap, the second abutting surface abuts against the stop part, and the inclined surface gradually pushes against the filter body in the direction of the installation channel. After the first abutting surface abuts against the filter body, it can restrict the filter body from moving in the direction away from the installation channel.

[0022] Furthermore, the fastener also has a hook, and the hook and the limiting part are located on opposite sides of the fastener. The bidet body has a corresponding hole, so that after the hook is inserted and hooks onto the side wall of the hole, the fastener is restricted from moving up and down. The limiting part can rotate up and down around one end of the hook, so that when the limiting part rotates downward, it is inserted into the installation gap, and when the limiting part rotates upward, it is removed from the installation gap.

[0023] Furthermore, the connection between the connector and the mounting channel is threaded.

[0024] The beneficial effects of this utility model after adopting the above solution are as follows: By installing the filter body as a whole on the housing of the bidet, when the filter body is installed on the housing, the water inlet of the filter chamber is connected to the water inlet channel, and the water outlet of the filter chamber is connected to the water outlet channel. That is, the external water source enters the filter water inlet chamber through the water inlet channel and the water inlet of the filter chamber. After filtration, it flows into the filter water outlet chamber, reaches the water outlet channel through the filter water outlet, and is sprayed out from the nozzle. While ensuring the water quality of the water from the nozzle, the filter body is installed on the bidet body and can be disassembled as a whole, which is convenient to operate. It is convenient to replace the filter element inside the filter body after the filter body is completely disassembled, making it easy to use. Attached Figure Description

[0045] Key points combined Figure 5 As shown, the housing 21 is provided with an installation port 25, which extends into the housing 21 to form an installation channel 26. The water inlet channel 22 and the water outlet channel 23 extend into the installation channel 26, focusing on... Figure 6 As shown, a connector 15 is formed at one end of the filter body 1. The filter chamber inlet 13 and the filter chamber outlet 14 are formed on the connector 15 so that when the connector 15 is inserted from the mounting port 25 and sealed in the mounting channel 26, the filter chamber inlet 13 is connected to the inlet channel 22 and the filter chamber outlet 14 is connected to the outlet channel 23.

[0046] In this specific embodiment, the end of the plug 15 protrudes to form an outlet connector 16, the filter chamber outlet 14 is formed on the outlet connector 16, and the filter chamber inlet 13 surrounds the outer periphery of the outlet connector 16. When the plug 15 is inserted from the mounting port 25 and sealed into the mounting channel 26, the outlet connector 16 is sealed into the inlet / outlet channel 23, so that the filter chamber outlet 14 is connected to the inlet channel 22. The inlet channel 22 surrounds the outer periphery of the outlet channel 23 and is connected to the filter chamber inlet 13. Specifically, there are four filter chamber inlets 13 arranged in a ring array on the end face of the plug 15, which can make the water flow from the inlet channel 22 enter the filter inlet chamber 11 more evenly. Of course, in other embodiments, the number of filter chamber inlets 13 can also be two, three, five or others, without specific limitation.

[0047] Key points combined Figure 4As shown, in order to prevent water from leaking out of the outlet connector 16, a first water seal 3 is also included. The first water seal 3 is sealed between the outlet connector 16 and the water outlet channel 23. Specifically, a first annular groove 161 is formed on the outer side of the outlet connector 16. The first water seal 3 is specifically a first annular sealing ring 31. The first annular sealing ring 31 is embedded in the first annular groove 161.

[0049] Key points combined Figure 5 As shown, the connector 15 and the mounting channel 26 are engaged by a snap-fit ​​mechanism. Specifically, a slot 27 is formed on the inner wall of the mounting channel 26, and a locking block 17 protrudes from the outer wall of the connector 15. A socket 28 is formed on the slot 27 for the locking block 17 to be inserted. After the connector 15 is inserted into the mounting channel 26, the locking block 17 aligns with the socket 28 and rotates around the axis from the socket 28 to engage with the slot 27, thereby restricting the locking block 17 from sliding axially. In use, the connector 15 is inserted into the installation channel 26 from the installation port 25. Rotating the connector 15 easily fixes the filter body 1 onto the bidet body 2. When disassembling, rotating the connector 15 in the opposite direction releases the restriction between the locking block 17 and the locking groove 27, allowing the connector 15 to exit from the installation channel 26.

Specifically, the connector 15 can protrude from any position of the main body 18, and the main body 18 located outside the mounting channel 26 can be easily held by hand, making it easy to install and remove the filter body 1.

[0053] Preferably, the filter body 1 has a cylindrical structure, the connector 15 protrudes from one end of the main body 18, and the outer surface of the main body 18 has a number of anti-slip textures 8.

[0054] Example 2

[0055] like Figure 8-13 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the method of fixing the filter body 1 and the bidet body 2. The key difference is the combination of... Figure 12 As shown, it also includes a fixing member 6, which is detachably installed on the bidet body 2. A limiting part 61 is formed on the fixing member 6. After the fixing member 6 is installed on the bidet body 2, the limiting part 61 abuts against the filter body 1, restricting the filter body 1 from moving in the direction away from the installation channel 26.

[0056] In this specific embodiment, the direction in which the connector 15 of the filter body 1 exits from the installation channel 26 is perpendicular to the direction in which the fixing member 6 is removed from the bidet body 2, so as to avoid the fixing member 6 being pushed out of the bidet body 2 and removed when the filter body 1 exits from the installation channel 26, thus making the installation more secure.

[0057] Key points combined Figure 8-10As shown, a mounting groove 211 for installing the filter body 1 is formed on the bidet body 2. The mounting groove 211 protrudes from the side wall of the housing 21 of the bidet body 2. Preferably, the mounting groove 211 protrudes from the top side of the bidet body 2 for easy installation and removal. The fixing member 6 can block the mounting groove 211 downwards, restricting the filter body 1 from being removed from the mounting groove 211. The fixing member 6 can be removed from the bidet body 2 upwards. After the fixing member 6 blocks the mounting groove 211, the fixing member 6 and the bidet body 2 are combined to form a complete bidet body. The profile is more aesthetically pleasing and complete; in addition, the installation channel 26 is formed in the installation groove 211 and extends laterally. After the filter body 1 is placed into the installation groove 211, it is inserted laterally into the installation channel 26 so that the connector 15 is inserted into the installation channel 26, or it is moved away from the installation channel 26 so that the connector 15 is laterally removed from the installation channel 26; when the connector 15 is inserted into the installation channel 26, the main body 18 of the filter body 1 is placed on the bottom wall of the installation groove 211, and the installation groove 211 can provide support for the main body 18.

[0058] Key points combined Figure 11 As shown, a stop portion 212 is formed in the mounting groove 211, and the stop portion 212 faces the mounting channel 26. After the filter body 1 is installed in the mounting groove 211, the stop portion 212 is spaced apart from the filter body 1 to form a mounting gap 7. When the fixing member 6 blocks the mounting groove 211, the limiting part 61 is inserted into the mounting gap 7 to abut against the filter body 1; then focus on the connection. Figure 13 As shown, preferably, the limiting part 61 facing the filter body 1 has a first abutting surface 611 and an inclined surface 613 formed sequentially from the fixing member 6 to the mounting groove 211. The first abutting surface 611 is perpendicular to the direction in which the plug 15 exits from the mounting channel 26, and the inclined surface 613 is inclined and recessed inward toward the mounting groove 211. The limiting part 61 facing away from the filter body 1 has a second abutting surface 612 formed. The second abutting surface 612 is used to abut against the stop part 212 so that when the limiting part 61 is inserted into the mounting gap 7, the second abutting surface 612 abuts against the stop part 212. As the limiting part 61 is gradually inserted into the mounting gap 7, the inclined surface 613 is gradually pushed against the filter body 1 toward the mounting channel 26 until the first abutting surface 611 abuts against the filter body 1, thus restricting the filter body 1 from moving away from the mounting channel 26, so that the filter body 1 is installed in the mounting groove 211.

[0059] Furthermore, a hook 62 is formed on the fixing member 6. The hook 62 and the limiting part 61 are located on opposite sides of the fixing member 6. A locking hole 213 corresponding to the hook 62 is formed on the body of the bidet 2. After the hook 62 is inserted and hooks the side wall of the locking hole 213, the fixing member 6 is restricted from moving up and down. The limiting part 61 can rotate up and down around one end of the hook 62. When the limiting part 61 rotates downward, it is inserted into the installation gap 7. When the limiting part 61 rotates upward, it is disengaged from the installation gap 7. When the limiting part 61 rotates upward to a certain angle, the hook 62 is disengaged from the locking hole 213, so that the fixing member 6 can be removed from the body of the bidet 2.

[0060] To facilitate disassembly, the rear end of the fastener 6 is also provided with a disassembly part 63, so that after the fastener 6 blocks the mounting groove 211, the disassembly part 63 protrudes from the outer wall of the mounting groove 211, making it easy to hold by hand.

[0061] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
