Description

Split type closestool

Technical Field

The invention belongs to the technical field of sanitary wares, and particularly relates to a novel split type closestool.

Background

Toilets such as toilets and urinals are common sanitary appliances in daily life, and can be mainly divided into siphoning type toilets and direct discharging type toilets; the first is that the inside of the toilet is provided with an inverted S-shaped trap, and the siphon action is generated by the rising of the liquid level in the liner to discharge the dirt in the liner, so the toilet is the most mature and traditional toilet structure. However, the siphon toilet also has the disadvantages of large water requirement for flushing, easy backflow after the main pipeline is blocked, incapability of blocking small animals (flies, mice and the like) from entering and the like.

The direct discharge type toilet bowl largely overcomes the above disadvantages of the siphon type toilet bowl, but is more complicated in its realization structure and various in its valve structure. Most of the existing direct-discharging toilets are driven by a motor, and when the toilet needs to be flushed, a user operates or generates a control signal through induction, so that the motor drives a valve mechanism to open after actuating; however, in practical use, if special situations such as power failure and motor damage occur, the valve mechanism may not be normally opened, water is not stored in the liner of the direct-discharge toilet stool (or a very small amount of water is only filled before use, which can be ignored basically), and the abnormal opening of the valve can cause serious odor in the bathroom, which is not beneficial to daily use. However, in many cases, the conventional direct discharge control mechanism of the toilet cannot be compatible with motor control and manual control, and even if the mechanism can be compatible with motor control and manual control, the structure is relatively complex, and the cost is high, so that the mechanism is not favorable for popularization.

In addition, current closestool no matter be hydrocone type or direct vent, all adopt ceramic to make, because material and technology limit, the structural configuration of traditional closestool often is unreasonable, and electronic or intelligent part often is external or the mode of additional shaping holding portion is settled, is unfavorable for whole pleasing to the eye and part installation.

Therefore, it is necessary to redesign the structure of the existing toilet or the flushing mechanism thereof, and develop a new toilet structure.

Detailed Description

In order that those skilled in the art will better understand the invention and thus more clearly define the scope of the invention as claimed, it is described in detail below with respect to certain specific embodiments thereof. It should be noted that the following is only a few embodiments of the present invention, and the specific direct description of the related structures is only for the convenience of understanding the present invention, and the specific features do not of course directly limit the scope of the present invention. Such alterations and modifications as are made obvious by those skilled in the art and guided by the teachings herein are intended to be within the scope of the invention as claimed.

As shown in fig. 1-6, a split toilet comprises a base, a toilet inner container 13 is arranged in the base, an inner container opening is formed at the upper part of the base for use, and a drainage opening is arranged at the bottom of the toilet inner container 13 for discharging dirt. The closestool comprises a lower closestool body 11, a middle plate 12 and a cover plate 14, wherein an inner cavity is formed in the lower closestool body 11, and a closestool inner container 13 is matched in the inner cavity; meanwhile, the space between the inner container 13 and the inner cavity of the lower barrel 11 is also used for arranging other components of the split toilet, such as a water tank, a valve mechanism, a motor, a control mechanism and the like, so that the integrated toilet shown in fig. 1 is formed.

The upper part of the toilet inner container 13 is fixed on the middle plate 12 to form a whole; the middle plate 12 is fixed on the lower barrel 11, and the cover plate 14 is connected with the middle plate 12 to form the split-type toilet. Preferably, the lower barrel 11, the middle plate 12 and the cover plate 14 are connected in sequence, so that the inner container 13 of the toilet bowl is firmly fixed and the overall appearance is beautiful.

To connect the cover plate 14 and the middle plate 12, a clamping mechanism is disposed therebetween to connect the two. The clamping mechanism comprises a clamping column 17 and a clamping hole 18, a locking block 172 is arranged at the front end of the clamping column 17, and the locking block 172 and the main body of the clamping column 17 form an L-shaped structure; as shown in fig. 6, during connection, the locking post 17 is inserted into the locking hole 18 along the vertical direction, and then displaced along the horizontal direction, so that the locking block 172 is engaged with the inner wall of the locking hole 18, thereby fixedly connecting the cover plate 14 to the middle plate 12. For example, as shown in fig. 6, the locking column 17 is composed of a fixing seat 171, a locking block 172 and a fixing screw 173, the fixing seat 171 is fixed on the bottom of the cover plate 14, and the locking block 172 is connected with the fixing seat 171 through the fixing screw 173.

In a preferred case five, the fastening hole 18 is a through hole penetrating through the middle plate 12; after locking, the locking piece 172 is matched with the bottom surface of the middle plate 12; of course, the locking hole 18 may be an "L" shaped through hole that does not penetrate the middle plate 12, so that the locking can be realized.

In terms of materials, the lower barrel body 11, the middle plate 12, the toilet liner 13 and the cover plate 14 are made of polymer materials such as plastics or melamine and the like, so as to be used for manufacturing and assembling the toilet and realize modular design, manufacturing and assembling of each component.

As shown in fig. 7-25, a split type direct discharge toilet comprises a base, a toilet inner container 12 is arranged in the base, a water outlet for discharging the sewage and water in the inner container is arranged at the bottom of the toilet inner container 12, and a ball valve mechanism 2 is arranged below the water outlet to control the opening and closing of the water outlet, so as to form the split type direct discharge toilet.

The ball valve mechanism 2 mainly comprises a first ball valve member 21, a second ball valve member 22 and a valve ball 23, wherein the first ball valve member 21 and the second ball valve member 22 are matched to form a discharge pipeline, and the valve ball 23 is arranged in the discharge pipeline and rotates to control the opening and closing of the discharge pipeline; for example, as shown in fig. 15 and 24, the ball valve mechanism 2 is formed by a first ball valve member 21 located at the upper portion and a second ball valve member 22 located at the lower portion, with a valve ball 23 disposed therebetween. Of course, it may be formed by matching left and right halves.

The toilet further includes a ball control device 100 for controlling the opening and closing of the ball 23. As shown in fig. 16-25, the valve ball control device 100 includes a base plate 110, a manual mechanism 120, a transmission mechanism 130, and a motor 140.

At least one chute mechanism 111 is disposed on the bottom plate 110, and the chute mechanism 111 includes a slope 1111. As shown in fig. 18, the chute mechanism 111 preferably comprises two inclined surface portions 1111 and a concave hole portion 1112 located at the middle of the bottom of the two inclined surface portions 1111.

The manual mechanism 120 is provided with a top pin 121 which can be matched with the chute mechanism 111, the manual mechanism 120 is pivotally matched with the bottom plate 110, when the manual mechanism 120 rotates relative to the bottom plate 110, the top pin 121 makes a circumferential displacement along the inclined surface portion 1111, so that the manual mechanism 120 generates an axial displacement relative to the bottom plate 110 to relatively approach or depart from; for example, when the top pin 121 is displaced from the recessed hole 1112 of the chute mechanism 111 onto the surface of the base plate 110, the manual mechanism 120 is displaced axially relative to the base plate 100 due to the difference in depth between the recessed hole 1112 and the surface.

In addition, the manual mechanism 120 further includes a first transmission mechanism 122, and the output mechanism 130 includes a second transmission mechanism 132 capable of cooperating with the first transmission mechanism 122; one end of the transmission mechanism 130 is formed as an output end 131 connected to the valve ball 23. When the manual mechanism 120 is axially displaced relative to the base plate 110, the manual mechanism 120 engages the output 131 via the first and second actuators 122, 132, such that the manual mechanism 120 in this case can drive the valve ball 23 to rotate to open or close.

The transmission mechanism 130 is further provided with a first coupling portion 133, an output shaft 141 of the motor 140 is provided with a second coupling portion 134, and the first coupling portion 133 and the second coupling portion 134 are coupled, so that the motor 140 can drive the valve ball 23 to rotate to open or close.

In the above toilet, the motor 140 is always connected to the ball valve 23, and the manual mechanism 120 is connected thereto after being subjected to a force and is disconnected without being subjected to a force; this meets the most basic operating requirements, but the motor becomes a force-bearing part in manual operation, which not only increases the resistance but also is disadvantageous for the motor (technically fully feasible).

In order to overcome the above disadvantages, the output mechanism 130 further includes a separating mechanism 135, the separating mechanism 135 is disposed adjacent to the first coupling portion 133, and the separating mechanism 135 is located at a side close to the bottom plate 110, when the manual mechanism 120 is forced to drive it to generate an axial displacement, the first coupling portion 133 changes from a coupling state with the second coupling portion 134 to a mating state with the separating mechanism 135, and the first coupling portion 133 is disposed in a freely rotatable manner relative to the separating mechanism 135; the transmission mechanism 130 is fitted to the ball valve 23 in such a manner as to be axially displaceable. Therefore, when a force is applied to the manual mechanism 120, the manual mechanism 120 is axially displaced relative to the base plate 110, the first coupling portion 133 and the second coupling portion 134 are decoupled and engaged with the separation mechanism 135, and the transmission mechanism 130 and the ball valve 23 are still engaged in the process; that is, after the manual mechanism 120 is forced, it is successfully connected to the ball valve 23, and the motor 140 is separated from the ball valve 23, so that the motor is not affected in the case of manual operation.

In this case, the problem of stress on the motor is solved, but the problem is still somewhat insufficient; that is, the output shaft 141 and the ball valve 23 are engaged in a manner that allows a range of axial displacement, such as by a shaft member and a sleeve; of course, an elastic member may be required to be arranged between the two for resetting.

As shown in fig. 22, for structural optimization, the transmission mechanism 130 may be composed of a first transmission piece 1301, a second transmission piece 1302 and an elastic piece 1303, and the output end 131 is disposed outside the first transmission piece 1301; the inner side of the first transmission piece 1301 is provided with a third coupling part 137, the outer side of the second transmission piece 1302 is formed as a fourth coupling part, and the elastic piece 1303 is arranged between the first transmission piece 1301 and the second transmission piece 1302; the first coupling portion 133 is disposed on the second transmission member 1302 and disposed on the outer side, and the separating mechanism 135 is disposed on the inner side of the second transmission member 1302.

In this toilet, the third coupling part 137 is a track-shaped recess hole formed in the inner side of the first transmission member 1301, the second transmission member 1302 has a track shape matching with the recess hole so that the outer side of the second transmission member 1302 is integrally formed as a fourth coupling part, and the separation mechanism 135 may be a rectangular recess hole; the first transmission mechanism 122 is a concave hole or a convex block; the second transmission mechanism 132 can be a projection or a recess matched with the second transmission mechanism; the first coupling part 133 may be a pin hole, and the second coupling part 134 may be a pin accordingly.

In this way, the direct rigid connection between the output end 131 and the valve ball 23 can be provided, and the above-mentioned axial movable fit is provided in the transmission mechanism 130, which is more advantageous for the control of the toilet and is more convenient for manufacturing, assembling and maintaining.

In some embodiments, the ball control device 100 further includes a front plate 112, and the front plate 112 is fixed to the bottom plate 110 at a distance such that the manual mechanism 120 and the transmission mechanism 130 are disposed therebetween, thereby forming a relatively complete ball control device 100. It is understood that the front plate 112 may be employed to form a unitary structure, whether the actuator 130 is axially displaceably movably engaged with the ball valve 23 as a whole, or whether the actuator 130 is axially displaceably movably disposed within and rigidly connected at its output end 131 to the ball valve 23. For example, the bottom plate 100 and the front plate 112 are connected by screws, and the spacer 113 is provided therebetween to fix them at a distance.

In other embodiments, the toilet further comprises a water tank 31, a water inlet fitting 32, a booster pump 33, a flush dispense fitting 34; the water inlet connector 32 is connected with the water inlet of the water tank 31 through a water inlet pipe 301, a water inlet valve is arranged between the water inlet pipe 301 and the water tank 31 to control the on-off of water inlet, and the water inlet of the water tank 31 is connected with the booster pump 33 and then communicated to the flushing distribution connector 34 through a water outlet pipe 302.

And, the toilet further comprises a manual valve 35; the manual valve 35 is connected to the manual arm 123 of the manual mechanism 120 via the link mechanism 36, so that the manual arm 123 is moved while the manual valve 35 is driven to open; the inlet of the manual valve 35 is connected to the water inlet connection 32 via a manual inlet pipe 303 and the outlet thereof is connected to the flush distribution connection 34 via a manual outlet pipe 304. Preferably, an overflow pipe 305 is further included, one end of which communicates to the upper portion of the tank 301 and the other end communicates to a discharge line or outlet toilet at the rear of the valve ball.

Thus, two modes of manual control and automatic control of flushing can be realized, wherein the automatic control can be started by starting the booster pump 33 through an electric signal, and the manual control is started by applying force to the manual mechanism 120 to drive the manual valve 35 to be opened.

In other embodiments, the toilet further comprises a vent assembly comprising a suction mechanism and a vent mechanism, as shown in fig. 26-28, 14-15.

The air suction mechanism is formed by a middle plate 12 and a cover plate 14, the cover plate 14 and the middle plate 12 are arranged at intervals to form an air suction cavity between the two; the cover plate 14 extends downwards along the mouth part 13a of the inner container to form a first air suction piece 4031; a second air suction piece 4032 is formed on the middle plate 12 along the edge of the inner container opening 13a, the first air suction piece 4031 is matched in the second air suction piece 4032, and the first air suction piece 4031 and the second air suction piece 403are matched to form an air suction port; the middle plate 12 is provided with an exhaust port 1201 for connecting an air duct thereto.
