Description

Technical Field

[0001] This utility model relates to the field of sanitary equipment technology, and in particular to a smart toilet switch assembly and a smart toilet. Background Technology

[0002] As people's living standards continue to improve, smart toilets are increasingly widely used in daily life, bringing users a great sense of comfort through their convenience and hygiene. Currently, smart toilet sensor switches on the market mainly use infrared sensors, laser sensors, and capacitive sensors to achieve functions such as lid opening and seat opening.

[0003] However, existing technologies have some problems that urgently need to be solved. On the one hand, these sensor switches require electronic control components to function properly, which undoubtedly increases the production cost of smart toilets and affects their price competitiveness in the market. On the other hand, the use of electronic control components may also increase system complexity, thereby reducing the reliability and stability of the product to some extent and causing potential inconvenience to users. For example, false triggering or insensitive sensing may occur during use, affecting the normal use and good experience of the smart toilet.

[0004] Therefore, there is an urgent need for a smart toilet sensor switch technology that can effectively reduce costs and has a simple and reliable structure, in order to overcome the shortcomings of existing technologies and meet the market and users' demand for high-performance, cost-effective smart toilets.

[0005] To address the problems existing in the prior art, this utility model provides a smart toilet switch assembly and a smart toilet, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] According to one aspect of the present invention, the device includes: a housing and a pressing head, one end of the pressing head being movably inserted into the housing and the other end being exposed outside the housing; an elastic reset member being fitted between the pressing head and the housing; at least one end of the housing being provided with a slot; one end of the pressing head extending toward the slot being provided with a hook, and the hook being movably engaged with the slot; the device also includes a reed switch, one end of the housing being fitted with a reed switch, the reed switch being electrically connected to a control module; and one end of the pressing head being fixed with a magnet for opening and closing the reed switch.

[0008] Furthermore, a guide groove is provided above the card slot.

[0009] Furthermore, the inner circumferential surface of the outer shell is provided with a plurality of first positioning grooves at intervals, and the outer circumferential surface of the pressing head is provided with a plurality of first positioning protrusions at intervals, wherein the plurality of first positioning protrusions and the plurality of first positioning grooves are engaged.

[0010] Furthermore, a partition is provided on the inner circumferential surface of the outer shell, which divides the outer shell into an upper chamber and a lower chamber. The pressing head is located in the upper chamber, and the reed switch is located in the lower chamber. A first mounting groove for installing the reed switch is provided on the lower end face of the partition.

[0011] Furthermore, the elastic reset element is a compression spring, and an extension post is provided at one end of the partition extending toward the pressing head. The compression spring is sleeved outside the extension post, with one end of the compression spring abutting against the partition and the other end abutting against the pressing head.

[0012] Furthermore, the pressing head has a flange extending outward from the end away from the outer casing, and a gap is formed between the flange and the outer casing.

[0013] Furthermore, the central axis of the magnet coincides with the central axis of the reed switch, and the magnetic pole direction of the magnet is parallel to the extension direction of the reed inside the reed switch; in the unpressed state, there is a preset distance between the magnet and the reed switch.

[0014] According to another aspect of the present invention, a smart toilet includes a toilet body and a smart toilet switch assembly as described above, wherein the toilet body is provided with a mounting hole and the switch assembly is detachably fixed to the mounting hole.

[0015] Furthermore, it also includes a mounting base and a nut. One end of the mounting base passes through the mounting hole, and the outer peripheral surface of the mounting base is provided with an external thread. The nut is threadedly connected to the mounting base to fix the mounting base in the mounting hole. The outer shell is rotatably inserted into the mounting base. The mounting base is provided with at least one second positioning groove. At least one end of the outer peripheral surface of the outer shell extends toward the mounting base and is provided with a second positioning protrusion. The second positioning protrusion engages with the second positioning groove.

[0016] Furthermore, the second positioning groove is L-shaped.

[0017] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] Firstly, using reed switches instead of traditional infrared, laser, or capacitive sensors eliminates the need for complex electronic control components such as sensor chips and signal processing modules, significantly reducing material and production costs. Through a mechanical structure—the cooperation of a hook and slot—and a magnetic switch—the reed switch and magnet trigger signal—the number of electronic components is reduced, minimizing false triggering or insensitivity issues caused by electronic control malfunctions. The reed switch only responds to the magnetic field of the magnet at close range, avoiding interference from external factors such as ambient light and humidity, ensuring the stability and accuracy of signal transmission.

[0019] Secondly, the guide groove guides the hook to slide along a fixed path, preventing the pressing head from shifting or getting stuck, and ensuring the smoothness and repeatability of the pressing action.

[0020] Thirdly, the fitting design of the first positioning protrusion and the first positioning groove restricts the lateral displacement of the pressing head, which facilitates assembly.

[0021] Fourth, the partition separates the reed switch from the moving area of ​​the pressing head, preventing mechanical vibration or dust from affecting the sensitivity of the reed switch and improving the reliability of signal transmission.

[0022] Fifth, the extension column limits the radial offset of the compression spring, ensuring that the spring is compressed only along the axial direction, making the press head reset more quickly and smoothly.

[0023] Sixth, the gap provides reset space for the pressing head and limits its excessive pressing, preventing damage to internal components due to over-strength.

[0024] Seventh, the switch assembly is fixed by the mounting base and nut. The threaded connection design allows for quick disassembly and replacement of the switch assembly, reducing after-sales maintenance costs. The second positioning groove is L-shaped, which realizes the rotation positioning of the housing, simplifies the installation steps, avoids incorrect installation direction, and improves assembly efficiency.

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0037] like Figures 1 to 9 As shown, this solution provides a smart toilet switch assembly and a smart toilet.

[0038] Please see Figures 1 to 7According to one aspect of this utility model, the switch assembly 100 includes: a housing 1 and a pressing head 2. One end of the pressing head 2 is movably inserted into the housing 1, while the other end is exposed outside the housing 1. Specifically, a flange 24 extends outward from the end of the pressing head 2 away from the housing 1, and a gap 20 is formed between the flange 24 and the housing 1. An elastic reset member 4, which is a compression spring, is assembled between the pressing head 2 and the housing 1. At least one end of the housing 1 is provided with a slot 13, and one end of the pressing head 2 extends toward the slot 13 with a hook 21, which is movably engaged with the slot 13. In this embodiment, there are two slots 13, which are symmetrically arranged at both ends of the housing 1. Correspondingly, there are also two hooks 21, which cooperate with the two slots 13 respectively. Preferably, a guide groove 12 is provided above the slot 13.

[0039] Please see Figures 1 to 7 The system also includes a reed switch 7. One end of the housing 1 is fitted with the reed switch 7, which is electrically connected to the control module (not shown). Specifically, one end of the reed switch 7 is electrically connected to a wire 71, which connects to the control module. A magnet 3 for opening and closing the reed switch 7 is fixed to one end of the pressing head 2. In this embodiment, a second mounting groove 23 is provided at the lower end of the pressing head 2, and the magnet 3 is fixed to this second mounting groove 23 with adhesive. Of course, in other embodiments, the magnet 3 can also be fixed to the lower end of the pressing head 2 in other ways; the fixing method is not limited here. The central axis of the magnet 3 coincides with the central axis of the reed switch 7. This design ensures that the magnetic field uniformly covers the reed of the reed switch 7, avoiding signal offset. The magnetic pole direction of the magnet 3 is parallel to the extension direction of the reed inside the reed switch 7; specifically, the N and S magnetic pole directions of the magnet 3 are parallel to the extension direction of the reed inside the reed switch 7. This parallel arrangement allows the magnetic field lines to pass perpendicularly through the reed contact point, maximizing magnetic flux utilization and reducing the magnetic induction intensity required for triggering. In the unpressed state, there is a preset distance between the magnet 3 and the reed switch 7. This distance is sufficient to ensure that the magnet 3 is not within the effective sensing range of the reed switch 7 when not pressed. The reed switch 7 is a direct application of existing technology, and its working principle will not be elaborated here.

[0040] A partition 17 is provided on the inner circumferential surface of the outer casing 1, dividing the outer casing 1 into an upper chamber 18 and a lower chamber 10. The pressing head 2 is located in the upper chamber 18, and the reed switch 7 is located in the lower chamber 10. A first mounting groove 15 for mounting the reed switch 7 is provided on the lower end surface of the partition 17. A limiting groove 16 for limiting the movement of the wire 71 is also provided on the lower end surface of the partition 17. An extension post 171 extends from one end of the partition 17 toward the pressing head 2. A compression spring is sleeved on the extension post 171, with one end of the compression spring abutting against the partition 17 and the other end abutting against the pressing head 2.

[0041] Please see Figures 1 to 7The inner circumferential surface of the outer shell 1 is provided with a plurality of first positioning grooves 11 at intervals, and the outer circumferential surface of the pressing head 2 is provided with a plurality of first positioning protrusions 22 at intervals, and the plurality of first positioning protrusions 22 fit into the plurality of first positioning grooves 11.

[0042] Please see Figures 1 to 9 According to another aspect of this utility model, a smart toilet includes a toilet body 200 and a smart toilet switch assembly as described above. The toilet body 200 is provided with a mounting hole, and the switch assembly 100 is detachably fixed in the mounting hole. Specifically, it also includes a mounting base 5 and a nut 6. One end of the mounting base 5 passes through the mounting hole, and the outer peripheral surface of the mounting base 5 is provided with an external thread. The nut 6 is threadedly connected to the mounting base 5, so that the mounting base 5 is fixed in the mounting hole. The outer shell 1 is rotatably inserted into the mounting base 5. The mounting base 5 is provided with at least one second positioning groove 52. At least one end of the outer peripheral surface of the outer shell 1 extends toward the mounting base 5 and is provided with a second positioning protrusion 14, which engages with the second positioning groove 52. Preferably, the second positioning groove 52 is L-shaped. In this embodiment, there are two second positioning grooves 52, and the two second positioning grooves 52 are mirror images of each other on the mounting base 5. The lower end face of the mounting base 5 is provided with at least one wire hole 51. The wire hole 51 is located below the second positioning groove 52. Preferably, there are two wire holes 51, which are symmetrically arranged on the mounting base 5.

[0043] Working principle:

[0044] When the user applies external force to the end of the pressing head 2 exposed outside the outer casing 1, the pressing head 2 moves downward along the inner cavity of the outer casing 1, causing the magnet 3 fixed at its end to move synchronously. At this time, the hook 21 slides in the slot 13, and the first positioning protrusion 22 cooperates with the first positioning groove 11 to ensure the stability of the vertical movement trajectory of the pressing head 2. During this process, the elastic reset member 4 compresses the spring, accumulating elastic potential energy.

[0045] As the pressing head 2 moves downward, the magnet 3 approaches the reed switch 7. When the magnet 3 enters the effective sensing range of the reed switch 7, the reed switch 7 closes under the action of the magnetic field, conducting the circuit signal and transmitting the signal through the wire 71 to the control module of the smart toilet, triggering the toilet body 200 to perform corresponding functions such as opening the lid and opening the seat. The partition 17 divides the outer shell 1 into an upper chamber 18 and a lower chamber 10, effectively isolating the moving areas of the reed switch 7 and the pressing head 2, avoiding mechanical interference.

[0046] When the user removes the external force, the elastic reset component 4 releases its elastic potential energy, pushing the press head 2 upwards to reset. The magnet 3 then moves away from the reed switch 7, causing the reed of the reed switch 7 to separate, breaking the circuit and terminating signal transmission. The gap 20 between the flange 24 and the outer casing 1 provides travel space for the press head 2 to reset, while the engagement of the hook 21 and the slot 13 limits the upper limit of the press head 2's reset, ensuring stable component reset.

[0047] Furthermore, the switch assembly 100 is fixed to the mounting hole of the toilet body 200 by the mounting base 5 and the nut 6. During installation, the second positioning protrusion 14 engages with the L-shaped second positioning groove 52 in the mounting base 5 to achieve circumferential positioning of the outer casing 1; the wire hole 51 facilitates the passage of the wire 71 and its connection to the control module. This structural design makes the switch assembly 100 detachable and its installation direction adjustable, facilitating maintenance and adaptation to different toilet models.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
