Description

Technical Field

[0001] The invention relates to sanitary appliances, in particular to a toilet seat cover and a control method thereof. Background Art

[0002] To achieve the hot air drying function, existing toilet seats generally have a blower assembly installed on the main body. The blower assembly includes a fan and an air outlet duct, with the inlet of the air outlet duct connected to the outlet of the fan. In one model, the outlet of the air outlet duct includes an upper air outlet and a lower air outlet, with the upper air outlet located above the lower air outlet. The air volume of the upper and lower air outlets is adjusted by controlling the opening of the upper and lower air outlets to achieve a drying effect on different parts of the human body. The specific control method is to respectively install an upper baffle and a lower baffle at the upper and lower air outlets, and then set a drive motor to drive the upper and lower baffles to adjust the air volume of the upper and lower air outlets. This structure requires a drive motor and corresponding control circuit to implement, resulting in high production costs and more complex assembly. Summary of the Invention

[0003] One of the purposes of the present invention is to provide a toilet seat cover that simplifies the driving method of the upper baffle and the lower baffle and reduces the production cost.

[0005] Furthermore, the lower baffle moves from the fifth position to the fourth position by the suction force generated by the reverse rotation of the fan, and the resistance at the hinge of the upper baffle is greater than the resistance at the hinge of the lower baffle.

[0006] Furthermore, an upper hinge shaft is provided at the upper air outlet, the upper baffle is hinged to the upper hinge shaft, and a damping structure is provided on the upper hinge shaft to increase the rotation resistance of the upper baffle.

[0007] Furthermore, the upper baffle moves from the second position to the first position by the suction force generated by the reverse rotation of the fan.

[0008] Furthermore, a movable hole is provided at the lower air outlet, a locking member is installed in the movable hole, and a locking groove is provided at the lower baffle. After the lower baffle moves to the fourth position, the locking member falls into the locking groove to lock the lower baffle.

[0009] Furthermore, the locking member is rotatably connected to the lower air outlet, and the lower baffle is provided with a locking groove. After the lower baffle moves to the fourth position, the bottom end of the locking member falls into the locking groove to lock the lower baffle.

[0010] Furthermore, the unlocking member includes an upper magnet arranged at the bottom of the upper baffle, the locking member is a ferromagnet or a ferromagnet is provided at the top of the locking member, and the unlocking member adsorbs the locking member after the upper baffle moves to the first position to lock the upper baffle, and at the same time makes the locking member disengage from the locking groove to unlock the lower baffle.

[0011] Furthermore, the lower baffle is provided with a blocking rib, which protrudes forward relative to the lower baffle. When the lower baffle is in the sixth position, the blocking rib blocks the movement path of the upper baffle.

[0012] One of the objectives of the present invention is to provide a method for controlling a toilet seat cover, wherein the toilet seat cover is the toilet seat cover of the first technical solution, wherein the resistance at the hinge of the upper baffle is greater than the resistance at the hinge of the lower baffle, and the thrust generated by the forward rotation of the fan unlocks the upper baffle, and the toilet seat cover has a first state, a second state, a third state, and a fourth state, wherein:

[0013] The first state is that the upper baffle is in the second position and the lower baffle is in the fifth position;

[0014] The second state is that the upper baffle is in the third position and the lower baffle is in the fourth position;

[0015] The third state is when the upper baffle is in the first position and the lower baffle is in the sixth position;

[0016] The fourth state is that the upper baffle is in the third position and the lower baffle is in the sixth position;

[0017] The control method includes the following contents:

[0018] When the toilet seat needs to move from the first state to the second state: the fan reverses and operates at the first power W1. The suction force F1 generated by the fan is greater than the resistance at the hinge of the lower baffle and less than the resistance at the hinge of the upper baffle, so that the lower baffle moves from the fifth position to the fourth position. The locking member locks the lower baffle in the fourth position. The fan rotates forward and operates at the second power W2. W2 is greater than W1. The thrust F2 generated by the fan is greater than the resistance at the hinge of the upper baffle, so that the upper baffle moves from the second position to the third position.

[0019] When the toilet seat needs to be restored from the second state to the first state, the fan reverses and operates at the second power W2. The suction force F2' generated by the fan is greater than the resistance at the hinge of the upper baffle, causing the upper baffle to move from the third position to the first position. The unlocking member unlocks the locking member. The fan rotates forward and operates at the third power W3 to unlock the upper baffle. Finally, the fan stops working, and the upper baffle naturally moves to the second position and the lower baffle naturally moves to the fifth position.

[0020] When the toilet seat needs to enter the third state from the first state, the fan reverses and operates at the second power W2. The suction force F2' generated by the fan is greater than the resistance at the upper baffle hinge and the resistance at the lower baffle hinge, so that the upper baffle moves from the second position to the first position and the lower baffle moves from the fifth position to the fourth position. The unlocking member keeps the locking member in the unlocked state and locks the upper baffle. The fan rotates forward and operates at a power not less than the first power W1 and less than the second power W2. The thrust generated by the fan is greater than the resistance at the lower baffle hinge and less than the resistance at the upper baffle hinge, so that the upper baffle remains locked and the lower baffle moves from the fourth position to the sixth position.

[0021] When the toilet seat needs to enter the first state from the third state, the fan rotates forward and operates at a power not lower than the second power W2, so that the upper baffle is unlocked, the fan stops working, and the upper baffle moves naturally to the second position, and the lower baffle moves naturally to the fifth position;

[0022] When the toilet seat needs to enter the fourth state from the first state, the fan rotates forward and works at a power not lower than the second power W2, so that the upper baffle moves to the third position and the lower baffle moves to the sixth position. The fan stops working, the upper baffle naturally moves to the second position, the lower baffle naturally moves to the fifth position, and the toilet seat enters the first state from the fourth state.

[0023] After adopting the above technical solution, the present invention has the following advantages: the upper baffle and the lower baffle are both driven by the wind generated by the fan, so there is no need to set up a special drive motor to drive them, which can save the cost of accessories and the corresponding assembly cost, thereby reducing the production cost of the toilet seat. Since the wind force generated by the fan is used purely to control the opening and closing of the upper baffle and the lower baffle, it is only necessary to control the forward and reverse rotation of the fan, which has high feasibility and good reliability. For this purpose, the upper baffle is specially designed to have a first position for closing the upper air outlet, a second position for natural rest, and a third position for opening the upper air outlet in sequence along the air outlet direction, and the lower baffle has a fourth position for closing the lower air outlet, a fifth position for natural rest, and a sixth position for opening the lower air outlet in sequence along the air outlet direction. The upper baffle and the lower baffle do not close the upper air outlet and the lower air outlet when they are naturally resting, and space for the upper baffle and the lower baffle to move in the opposite direction of the air outlet is reserved. Combined with the interaction between the locking part and the unlocking part, a variety of different states can be achieved, such as the upper baffle opens the upper air outlet and the lower baffle opens the lower air outlet, the upper baffle opens the upper air outlet and the lower baffle closes the lower air outlet, and the upper baffle closes the upper air outlet and the lower baffle opens the lower air outlet, so as to meet the different drying needs of users and thus improve the user experience.

[0044] The following specific embodiments are used to describe the technical solution of the present invention in detail.

[0045] Example 1:

[0046] like Figures 1 to 4 As shown, the present invention provides a toilet seat cover, comprising a body 1 and a blowing assembly provided on the body 1, the blowing assembly comprising a fan 2 and an air outlet channel 3, the inlet of the air outlet channel 3 being connected to the outlet of the fan 2, the outlet of the air outlet channel 3 comprising an upper air outlet 301 and a lower air outlet 302, the upper air outlet 301 being located above the lower air outlet 302, an upper baffle 31 driven by the wind force generated by the fan 2 being hinged at the upper air outlet 301, the upper baffle 31 sequentially having a first position for closing the upper air outlet 301 along the air outlet direction (refer to Figure 10 ), the second position of natural rest (see Figure 3 ), open the upper air outlet 301 to the third position (refer to Figure 9 ), the lower air outlet 302 is hinged with a lower baffle 32 driven by the wind generated by the fan 2, and the lower baffle 32 has a fourth position that closes the lower air outlet 302 along the air outlet direction (see Figure 8 ), the fifth position of natural stillness (see Figure 3 ), open the lower air outlet 302 to the sixth position (refer to Figure 12 ), a locking member 33 is provided at the lower air outlet 302, which can lock the lower baffle 32 in the fourth position, and the upper baffle 31 is provided with an unlocking member 34 which can unlock the locking member 33 and cooperate with the locking member 33 to lock the upper baffle 31 in the first position.

[0047] In the present invention, both the upper baffle 31 and the lower baffle 32 are driven by the wind generated by the fan 2, so there is no need to set up a special drive motor to drive them, which can save the cost of accessories and the corresponding assembly cost, thereby reducing the production cost of the toilet seat. Since the opening and closing of the upper baffle 31 and the lower baffle 32 are controlled purely by the wind generated by the fan 2, it is only necessary to control the forward and reverse movement of the fan 2, which has high feasibility and good reliability. For this purpose, the upper baffle 31 is specially designed to have a first position that closes the upper air outlet 301, a second position that is naturally still, and a third position that opens the upper air outlet 301 along the air outlet direction, and the lower baffle 32 has a fourth position that closes the lower air outlet 302, a fifth position that is naturally still, and a sixth position that opens the lower air outlet 302 along the air outlet direction. The upper baffle 31 and the lower baffle 32 are naturally still in the air outlet direction. When the upper air outlet 301 and the lower air outlet 302 are stationary, space is reserved for the upper baffle 31 and the lower baffle 32 to move in the opposite direction of the air outlet. In combination with the interaction between the locking member 33 and the unlocking member 34, a variety of different states can be achieved, such as the upper baffle 31 opening the upper air outlet 301 and the lower baffle 32 opening the lower air outlet 302, the upper baffle 31 opening the upper air outlet 301 and the lower baffle 32 closing the lower air outlet 302, and the upper baffle 31 closing the upper air outlet 301 and the lower baffle 32 opening the lower air outlet 302, so as to meet the different drying needs of the user and thus enhance the user's experience. It should be noted that the closing of the upper air outlet 301 or the lower air outlet 302 mentioned in the present invention does not necessarily require the air volume to be zero. It is just that due to the obstruction of the upper baffle 31 or the lower baffle 32, the air volume of the upper air outlet 301 or the lower air outlet 302 is no longer sufficient to dry the user's body surface.

[0048] Since the fifth position is relatively forward of the fourth position, the lower baffle 32 moves from the fifth position to the fourth position by the suction force generated by the reversal of the fan 2. In order to satisfy the movement of the lower baffle 32 while the upper baffle 31 does not move, the resistance at the hinge of the upper baffle 31 can be designed to be greater than the resistance at the hinge of the lower baffle 32. In this way, when the fan 2 reverses at the first power W1, the suction force F1 generated is sufficient to rotate the lower baffle 32 to move from the fifth position to the fourth position, but cannot move the upper baffle 31 from the second position to the first position. In this way, the upper baffle 31 can remain stationary, and the lower baffle 32 will close the lower air outlet 302. The lower baffle 32 can be locked by the locking member 33 to keep the lower air outlet 302 in a closed state. Specifically, as for the method of generating the damping effect, an upper hinge shaft 35 can be provided at the upper air outlet 301, and the upper baffle 31 is hinged to the upper hinge shaft 35. The upper hinge shaft 35 is provided with a damping structure that increases the rotation resistance of the upper baffle 31, for example Figure 5 As shown, the damping sleeve 351 that increases the rotational friction force, for example Figure 6As shown, a protrusion 352 is provided on the outer periphery of the upper hinge shaft 35 to increase the friction resistance during rotation. Other common structures that form a rotation damping effect can also be used.

[0049] Similar to the drive mechanism for the lower baffle 32, the upper baffle 31 is moved from the second position to the first position by the suction force generated by the reverse rotation of the fan 2. When the resistance at the hinge of the upper baffle 31 is greater than the resistance at the hinge of the lower baffle 32, the fan 2 needs to reverse and operate at the second power W2, so that the suction force F2' generated by the fan 2 is greater than the resistance at the hinge of the upper baffle 31, allowing the upper baffle 31 to rotate to the first position.

[0050] In one embodiment, a movable hole 303 is defined at the lower air outlet 302, a locking member 33 is mounted within the movable hole 303, and a locking slot 321 is defined in the lower baffle 32. After the lower baffle 32 moves to the fourth position, the locking member 33 falls into the locking slot 321, locking the lower baffle 32. The locking member 33 acts as a latch and can fall into the locking slot 321 by its own gravity. This simple and reliable operation requires only the lower baffle 32 to be rotated to the fourth position.

[0051] To unlock the lower baffle 32, the locking member 33 can be magnetically drawn out of the locking slot 321. Specifically, the following solution can be employed. The unlocking member 34 comprises an upper magnet disposed at the bottom of the upper baffle 31. The locking member 33 is ferromagnetic or has a ferromagnetic member at its tip. After the upper baffle 31 moves to the first position, the unlocking member 34 attracts the locking member 33 to lock the upper baffle 31, while simultaneously disengaging the locking member 33 from the locking slot 321 to unlock the lower baffle 32. The ingenuity of the present invention lies in the fact that the locking member 33 can both lock the lower baffle 32 in the fourth position and, in conjunction with the unlocking member 34, lock the upper baffle 31 in the first position. The unlocking member 34 serves both to unlock the lower baffle 32 and to lock the upper baffle 31. Because magnetic attraction is employed, as long as the forward rotation of the fan 2 generates sufficient thrust to overcome the magnetic attraction, the unlocking member 34 can separate from the locking member 33, naturally unlocking the upper baffle 31.

[0052] Taking into account that users have different requirements for the size of the wind force when using the single air outlet state with the lower air outlet 302 open and the upper air outlet 301 closed, in order to meet this demand of the user, that is, after the lower air outlet 302 is opened and the upper air outlet 301 is closed, the working power of the fan 2 can be adjusted according to the user's needs, but it will not affect the state of the lower air outlet 302 being opened and the upper air outlet 301 being closed. For this reason, in one embodiment, a blocking rib 322 can be provided on the lower baffle 32, and the blocking rib 322 protrudes forward relative to the lower baffle 32. When the lower baffle 32 is in the sixth position, the blocking rib 322 blocks the movement path of the upper baffle 31, such as Figure 12As shown, when the fan 2 operates at a higher power, the upper baffle 31 cannot open the upper air outlet due to the obstruction of the blocking rib 322, thereby meeting the user's demand for higher wind force. Since the thrust driving the lower baffle 32 to rotate is smaller than the thrust driving the upper baffle 31 to rotate, as long as the fan 2 maintains a power not less than the first power W1 and less than the second power W2, only the lower baffle 32 can be opened, and the upper baffle 31 cannot be opened, which can meet the user's demand for lower wind force.

[0053] Example 2:

[0054] In addition to sliding in the movable hole 303, in another embodiment, the locking member 33 can also be rotatably connected to the lower air outlet 302, such as Figure 7 As shown, after the lower baffle 32 moves to the fourth position, the bottom end of the locking member 33 falls into the locking groove 321 to lock the lower baffle 32 .

[0055] In addition to using magnetic adsorption to unlock the locking member 33, the unlocking member 34 can also be used to push. The top end of the locking member 33 is located on the movement path of the upper baffle 31 when it moves from the second position to the first position. The unlocking member 34 movably connects with the top end of the locking member 33 during the process of following the upper baffle 31 to move from the second position to the first position, so that the bottom end of the locking member 33 disengages from the locking groove 321 to unlock the lower baffle 32 and lock the upper baffle 31 at the same time. The upper baffle 31 is preferably connected to the top end of the locking member 33 by friction or adhesion, so that the fan can push the upper baffle 31 away from the first position when it rotates forward.

[0057] Example 3:

[0058] The present invention also provides a method for controlling a toilet seat cover, wherein the toilet seat cover is the toilet seat cover in the above embodiment, wherein the resistance at the hinge of the upper baffle 31 is greater than the resistance at the hinge of the lower baffle 32, and the thrust generated by the forward rotation of the fan 2 unlocks the upper baffle 31, and the toilet seat cover has a first state, a second state, a third state, and a fourth state, wherein:

[0059] The first state is that the upper baffle 31 is in the second position and the lower baffle 32 is in the fifth position. Figure 3 Standby state shown;

[0060] The second state is that the upper baffle 31 is in the third position and the lower baffle 32 is in the fourth position. Figure 9 The upper air outlet 301 is shown as being open and the lower air outlet 302 is closed in a single air outlet state;

[0061] The third state is that the upper baffle 31 is in the first position and the lower baffle 32 is in the sixth position. Figure 12The lower air outlet 302 is shown as being open and the upper air outlet 301 is closed in a single air outlet state;

[0062] The fourth state is that the upper baffle 31 is in the third position and the lower baffle 32 is in the sixth position. Figure 13 The upper air outlet 301 is open and the lower air outlet 302 is open.

[0063] The fifth state is that the upper baffle 31 is in the second position and the lower baffle 32 is in the sixth position. Figure 14 The lower air outlet 302 is shown as being open and the upper air outlet 301 is naturally stationary in a single air outlet state;

[0064] The control method includes the following contents:

[0065] In order to achieve a single air outlet state with the upper air outlet 301 open and the lower air outlet 302 closed, that is, when the toilet seat needs to enter the second state from the first state: the fan 2 is reversed and operates at the first power W1, and the suction force F1 generated by the fan 2 is greater than the resistance at the hinge of the lower baffle 32 and less than the resistance at the hinge of the upper baffle 31, so that the lower baffle 32 moves from the fifth position to the fourth position, as shown in FIG. Figure 8 As shown, the locking member 33 locks the lower baffle 32 in the fourth position, the fan 2 rotates forward and works at the second power W2, W2 is greater than W1, and the thrust F2 generated by the fan 2 is greater than the resistance at the hinge of the upper baffle 31, so that the upper baffle 31 moves from the second position to the third position, as shown in FIG. Figure 9 As shown;

[0066] When the toilet seat needs to be restored from the second state to the first state, the fan 2 is reversed and operates at the second power W2. The suction force F2' generated by the fan 2 is greater than the resistance at the hinge of the upper baffle 31, so that the upper baffle 31 moves from the third position to the first position. Figure 10 As shown, the unlocking member 34 unlocks the locking member 33. If the fan 2 stops working at this time, the upper baffle 31 will remain in the first position and the lower baffle 32 will naturally move from the fourth position to the fifth position. Figure 11 As shown, in order to unlock the upper baffle 31, the fan 2 needs to rotate forward and operate at the third power W3, which is not less than W2. The thrust F3 generated by the fan 2 separates the unlocking member 34 from the locking member 33, and the upper baffle 31 is unlocked. Finally, the fan 2 stops working, and the upper baffle naturally moves to the second position and the lower baffle naturally moves to the fifth position.

[0067] In order to achieve a single air outlet state with the lower air outlet 302 open and the upper air outlet 301 closed, that is, when the toilet seat needs to enter the third state from the first state, the fan 2 is reversed and operates at the second power W2. The suction force F2' generated by the fan 2 is greater than the resistance at the hinge of the upper baffle 31 and the resistance at the hinge of the lower baffle 32, so that the upper baffle 31 moves from the second position to the first position and the lower baffle 32 moves from the fifth position to the fourth position. Figure 10 As shown, the unlocking member 34 keeps the locking member 33 in the unlocked state and locks the upper baffle 31. The fan 2 rotates forward and operates at a power not lower than the first power W1 and lower than the second power W2. The thrust generated by the fan 2 is greater than the resistance at the hinge of the lower baffle 32 and less than the resistance at the hinge of the upper baffle 31, so that the upper baffle 31 remains locked and the lower baffle 32 moves from the fourth position to the sixth position, as shown in FIG. Figure 12 As shown;

[0068] When the toilet seat cover needs to enter the first state from the third state, the fan 2 rotates forward and operates at a power not lower than the second power W2 to unlock the upper baffle 31, and the fan 2 stops working, so that the upper baffle 31 moves naturally to the second position, and the lower baffle 32 moves naturally to the fifth position; it can be understood that if a blocking rib 322 is provided on the lower baffle 32, when the toilet seat cover needs to enter the first state from the third state, it is necessary to first stop the fan 2 and allow the lower baffle 32 to move naturally to the fifth position, and then the fan 2 rotates forward and operates at a power not lower than the second power W2 to unlock the upper baffle 31, and then the fan 2 stops working again, so that the upper baffle 31 moves naturally to the second position, and the lower baffle 32 moves naturally to the fifth position;

[0069] In order to realize the dual air outlet state of opening the upper air outlet 301 and opening the lower air outlet 302, that is, when the toilet seat cover needs to enter the fourth state from the first state, the fan 2 rotates forward and works at a power not lower than the second power W2, so that the upper baffle 31 moves to the third position and the lower baffle 32 moves to the sixth position. Figure 13 As shown, the fan 2 stops working, the upper baffle 31 naturally moves to the second position, the lower baffle 32 naturally moves to the fifth position, and the toilet seat cover enters the first state from the fourth state.

[0070] In order to realize the single air outlet state in which the lower air outlet 302 is open and the upper air outlet 301 is naturally still, the toilet seat cover can enter the fifth state from the first state, the fan 2 rotates forward and works at a power lower than the second power, the upper baffle 31 remains stationary, and the lower baffle 32 moves to the sixth position. Figure 14 As shown, the toilet seat cover can also enter the fifth state from the third state. The fan 2 rotates forward and operates at a power not lower than the second power W2, so that the upper baffle 31 is unlocked. The upper baffle 31 is blocked by the blocking rib 322 and stays in the second position. The lower baffle 32 is maintained in the sixth position. The fan 2 stops working, and the lower baffle 32 naturally moves to the fifth position. The toilet seat cover enters the first state from the fifth state.
