Description

Technical Field

[0001] The invention belongs to public environmental sanitary ware, and in particular relates to an automatic lifting device for a seat ring of an automatic toilet changer and a control method thereof. Background Art

[0002] Nowadays, ordinary people in China are paying more and more attention to public health and safety.

[0003] In public toilets, toilets are a widely used sanitary ware. Traditional public toilets use automatic toilet covers to avoid problems such as unsanitary conditions and cross infection caused by using toilets.

[0004] However, the traditional automatic cover-changing toilet seat requires the user to manually lower or raise the toilet seat when in use. The existing toilet seat with both automatic lifting and automatic cover-changing functions realizes the automatic lifting of the toilet seat by infrared sensing, rather than automatically lifting or lowering the seat. This requires the user to manually adjust the seat, and the traditional automatic cover-changing toilet seat can usually only perform the automatic cover-changing action after the seat is lowered, which makes it difficult to avoid the user's hands from contacting the unclean sanitary membrane.

[0005] Therefore, there is an urgent need for a device that can automatically change sleeves and automatically flip seat rings. Summary of the invention

[0006] To solve the above problems, the present invention is achieved as follows:

[0007] A seat automatic lifting device for an automatic sleeve-changing toilet, comprising a U-shaped seat, a toilet cover, an automatic sleeve-changing mechanism, and a mounting shell arranged on the toilet body, wherein the mounting shell comprises a mounting shell base, a mounting shell cover detachably arranged on the mounting shell base, a first mounting slot, a second mounting slot, and a third mounting slot are arranged in sequence from left to right in the mounting shell, the automatic sleeve-changing mechanism comprises a sleeve-discharging mechanism and a sleeve-collecting mechanism, a single end of the U-shaped seat is pivotally connected to the mounting shell base through a hinge shaft, and further comprises a power supply, a microwave sensing module, an electrical signal processing module, and a driving module, wherein the sensing module, the electrical signal processing module, and the driving module are in communication connection;

[0008] The microwave sensing module continuously detects the changes in the magnetic field in the surrounding space when powered on, and sends an electrical signal to the electrical signal processing module after detecting the changes in the electromagnetic field caused by the movement of the human body. The electrical signal processing module is connected to the enabling end of the driving module, and the electrical signal processing module amplifies the received electrical signal. The driving module works when receiving the amplified electrical signal.

[0009] The microwave sensing module comprises a microwave sensing device disposed in the second mounting groove;

[0010] The electrical signal processing module is an integrated amplifier circuit;

[0011] The driving module comprises a cover-lifting motor for driving the hinge shaft, and an automatic sleeve-changing mechanism connected to the cover-lifting motor via a speed-changing shaft.

[0012] As a further improvement, the lid-lifting motor is arranged outside the mounting shell, and the lid-lifting motor is directly connected to the hinge shaft; the lid-lifting motor is arranged on the side of the U-shaped seat ring close to the second mounting groove, or on the side of the U-shaped seat ring away from the second mounting groove.

[0013] As a further improvement, a cutting piece is provided at the pivotal connection between the U-shaped seat ring and the lid-lifting motor.

[0014] As a further improvement, the cover-lifting motor is arranged in the installation shell; the cover-lifting motor is arranged in the second installation groove, or is arranged in the third installation groove.

[0015] Preferably, the cover-lifting motor is a reduction motor, and the cover-lifting motor is connected to the hinge shaft via a variable speed transmission shaft.

[0016] As a further improvement, the seat ring is pivotally connected to a static-eliminating sheet at one end close to the first mounting groove, a wavy groove is provided on the static-eliminating sheet, and the static-eliminating sheet rests in the first mounting groove.

[0017] As a further improvement, the static electricity removal sheet is made of metal, the seat ring is made of insulating material, and a grounding wire connected to the static electricity removal sheet is arranged inside the seat ring.

[0018] A method for controlling an automatic lifting device for an automatic toilet seat changer comprises the following steps:

[0019] S1: The microwave sensing module continuously detects the magnetic field in the surrounding space. When a human body moves within the effective detection range of the microwave sensing module, the microwave sensing module generates an electrical signal and sends it to the electrical signal processing module;

[0020] S2: After receiving the electrical signal from the microwave sensing module, the electrical signal processing module amplifies the electrical signal and sends the amplified electrical signal to the driving module;

[0021] S3: After receiving the electrical signal from the electrical signal processing module, the driving module performs a corresponding driving action.

[0022] As a further improvement, S3 further includes the following steps:

[0023] S31: Start the automatic sleeve changing mechanism;

[0024] S32: After the automatic sleeve change is completed, the seat ring is turned over.

[0025] The beneficial effects of the present invention are:

[0026] By setting up a motor connected to the hinge shaft, the toilet seat can be automatically flipped up; by setting up a microwave sensing device, compared with the original infrared sensing device, it can also complete the sensing of the human body without setting a light window, avoiding the situation where the light window is blocked by urine stains or stains and the sensing is insensitive and cannot realize the function of automatic cover changing or lid flipping; by communicating and connecting the microwave sensing device, the lid-lifting motor and the automatic cover changing mechanism, the function of automatic cover changing and flipping up the seat can be realized synchronously after the microwave sensing device senses the human body.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0033] Embodiment 1

[0034] refer to Figures 1 to 3 , an automatic lifting device for a seat ring of an automatic sleeve-changing toilet, comprising a U-shaped seat ring 2, a toilet cover 0, an automatic sleeve-changing mechanism, and a mounting shell 1 arranged on a toilet body, the mounting shell 1 comprising a mounting shell base 12, a mounting shell 1 cover detachably arranged on the mounting shell base 12, a first mounting groove 121, a second mounting groove 122 and a third mounting groove 123 are arranged in sequence from left to right in the mounting shell 1, the automatic sleeve-changing mechanism comprises a sleeve-discharging mechanism and a sleeve-collecting mechanism, and a single end of the U-shaped seat ring 2 is pivotally connected to the mounting shell base 12 through a hinge shaft 23;

[0035] It also includes a power supply, a microwave sensing module 101, an electrical signal processing module 102, and a driving module 103, wherein the sensing module, the electrical signal processing module 102, and the driving module 103 are in communication connection;

[0036] The microwave sensing module 101 continuously detects the change of the magnetic field in the surrounding space when powered on, and sends an electrical signal to the electrical signal processing module 102 after detecting the change of the electromagnetic field caused by the movement of the human body. The electrical signal processing module 102 is connected to the enabling end of the driving module 103. The electrical signal processing module 102 amplifies the received electrical signal, and the driving module 103 works when receiving the amplified electrical signal.

[0037] The microwave sensing module 101 includes a microwave sensing device 3 disposed in the second mounting groove 122;

[0038] The electrical signal processing module 102 is an integrated amplifier circuit;

[0039] The driving module 103 includes a cover-lifting motor 4 for driving the hinge shaft 23 , and an automatic sleeve-changing mechanism connected to the cover-lifting motor 4 via a speed-changing shaft.

[0040] As a further improvement, the ejection mechanism includes a sanitary film sleeve 51 and a ejection roller 52 which are correspondingly arranged between the microwave sensing device 3 and the first mounting groove 121 .

[0041] As a further improvement, the collecting mechanism includes a collecting roller 53 correspondingly arranged between the microwave sensing device 3 and the third installation groove 123 .

[0042] Since the sanitary membrane of the automatic changing toilet is mostly made of polymer materials, and the toilet seat is generally made of ceramic or polymer materials, static electricity is easily generated due to friction during the automatic changing process, causing the sanitary membrane to be closely attached to the surface of the toilet seat, and it is easy to be damaged when changing the cover; or it is attached to the user's buttocks when the user leaves the seat, making the user feel uncomfortable and not hygienic enough; therefore, as a further improvement, the seat is pivotally connected to the anti-static sheet 21 at one end close to the first mounting groove 121, and a wavy groove is provided on the anti-static sheet 21, and the anti-static sheet 21 rests in the first mounting groove 121. By providing a wavy groove on the anti-static sheet 21, a certain gap exists between the sanitary membrane and the U-shaped seat 2 when the cover is removed, and the sanitary membrane is not closely attached to the surface of the U-shaped seat 2.

[0043] In order to eliminate static electricity, as a further improvement, the static electricity removal sheet 21 is made of metal, the seat ring is made of insulating material, and a grounding wire connected to the static electricity removal sheet 21 is arranged in the seat ring.

[0045] refer to Figure 1 As a further improvement based on the first embodiment, the cover-lifting motor 4 is arranged outside the mounting shell 1 , and the cover-lifting motor 4 is directly connected to the hinge shaft 23 .

[0046] Among them, when the lid-lifting motor 4 is arranged on the side of the U-shaped seat ring 2 close to the second mounting groove 122, the lid-lifting motor 4 is located above the bottom of the toilet pot and is easily contaminated with dirt. Therefore, as a preference, the lid-lifting motor 4 is arranged on the side of the U-shaped seat ring 2 away from the second mounting groove 122.

[0047] As a further improvement, a cutting piece 22 is provided at the pivotal connection between the U-shaped seat ring 2 and the cover-lifting motor 4 .

[0048] Embodiment 3

[0049] refer to Figure 3 As a further improvement based on the first embodiment, the cover-lifting motor 4 is arranged in the mounting shell 1 .

[0050] Since the U-shaped seat ring 2 is pivotally connected to the mounting shell base 12 at one end via a hinge shaft 23, when the lid-lifting motor 4 is disposed in the mounting shell 1, the motor cannot directly drive the hinge shaft 23 to control the flipping of the U-shaped seat ring 2. Therefore, as a further improvement, the lid-lifting motor 4 is a reduction motor, and the lid-lifting motor 4 is connected to the hinge shaft 23 via a speed change shaft.

[0051] As a further improvement, the cover-lifting motor 4 can be arranged in the first installation groove 121 , the second installation groove 122 or the third installation groove 123 .

[0052] Preferably, the cover-lifting motor 4 is disposed in the second mounting groove 122 or the third mounting groove 123 .

[0054] Based on the first embodiment, the second embodiment or the third embodiment, a control method for an automatic lifting device of a toilet seat with automatic changing cover is provided, comprising:

[0055] S1: The microwave sensing module 101 continuously detects the magnetic field in the surrounding space. When a human body moves within the effective detection range of the microwave sensing module 101, the microwave sensing module 101 generates an electrical signal and sends it to the electrical signal processing module 102;
