Description

Technical Field

[0001] This utility model relates to the field of psychological testing technology, specifically a psychological testing device. Background Technology

[0002] Sandplay therapy, a commonly used device in psychological testing, is widely applied in fields such as psychological counseling, psychotherapy, and psychological research. By having test subjects place various sand figures in the sand tray, their inner world and psychological state can be visually revealed, providing important analytical data for mental health professionals. However, because sandplay trays are typically used in open environments, the sand can easily become damp after prolonged use and may also contain a significant amount of debris, which can affect the proper use of the sandplay tray and the accuracy of the test results.

[0003] A search revealed a psychological testing device disclosed in Chinese Patent Publication No. CN220735402U. This device proposes controlling the opening and closing of two baffles by rotating a push rod through a handle in the opening and closing assembly. This allows sand to fall from the center of the main chamber into a sand storage box, facilitating the collection of old sand and saving time and effort for staff. Simultaneously, a cover plate can be installed on the top of the main chamber using a matching mounting block. When the device is not in use, the cover plate prevents debris from the external environment from entering the sand, maintaining its cleanliness.

[0004] However, this technical solution still has certain limitations. Although it can quickly collect and store old sand and protect the sand table, sand that has become damp or mixed with garbage and impurities still needs to be handled separately by staff. This includes drying the damp sand and screening the sand mixed with impurities. This is undoubtedly quite time-consuming and laborious, and it fails to fundamentally solve the problem of cumbersome sand handling. It cannot meet the needs of efficient and convenient psychological sand tables in actual use.

[0005] Therefore, this utility model provides a psychological testing device. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: A psychological testing device includes a main housing, a guide shell installed at the bottom of the main housing, a limiting ball rotatably connected to the inner wall of the guide shell, a feeder housing on one side of the main housing, wherein the limiting ball has a through hole, the upper opening of the through hole communicating with the internal space of the main housing, the lower opening of the through hole communicating with the internal space of the guide shell, a filter screen for filtering sand is provided on the inner wall of the through hole, the main housing communicates with the internal space of the guide shell, the guide shell communicates with the internal space of the feeder housing, a feeding port is provided on one side of the feeder housing, the feeding port corresponds to the position of the main housing, a rotating rod is rotatably connected to the inner wall of the feeder housing, a feeding propeller for guiding sand is installed on the side wall of the rotating rod, a drive mechanism for driving the rotating rod is installed at the top of the feeder housing, a collector ring is electrically connected to the bottom of the rotating rod, and the collector ring is installed at the bottom of the feeder housing.

[0008] Preferably, a connecting ring is installed at the top of the filter bag and is installed on the inner wall of the through hole. A counterweight rod is installed at the bottom of the filter bag. Neither the connecting ring nor the counterweight rod is in contact with the main housing. A weight-reducing hollow inner groove is formed inside the limiting ball.

[0009] Preferably, an L-shaped drive rod is installed on one side of the limiting ball, one end of the L-shaped drive rod is rotatably connected to the inner wall of the guide bottom shell, the other end of the L-shaped drive rod is rotatably connected to the outer side of the guide bottom shell, and a handle is rotatably connected to one side of the L-shaped drive rod.

[0010] Preferably, two limiting magnetic rods are installed on one side of the material guide bottom shell, and metal plates are embedded on both sides of the L-shaped drive rod. The metal plates are magnetically attracted to the corresponding limiting magnetic rods.

[0011] Preferably, a support base is installed at the bottom of the feeder housing, and the guide bottom shell and the main box are both located directly above the support base.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] (1) This utility model uses a filter bag to intercept and filter the passing sand, intercepting the garbage and impurities mixed in the sand. The filter bag is a soft filter structure, which can be pulled towards the main box, so that the filter bag is turned outward, making it easy to clean the garbage and impurities inside. It is simple and convenient to use. When the sand is guided upward by the rotating rod and the feeding propeller, it is heated to evaporate the moisture contained in the sand, thereby improving the use effect of the sand.

[0015] (2) Through the combined use of the bottom shell of the guide, the limiting ball and the outer shell of the feeder, the sand can be filtered, guided and heated to remove moisture in a timely manner after use. There is no need for staff to handle the sand separately. They only need to remove the garbage from the filter bag. The working process is time-saving and labor-saving, which can fundamentally solve the problem of cumbersome sand handling, thereby meeting the needs of efficient and convenient psychological sandplay in actual use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 A psychological testing device includes a main housing 1, a guide shell 2 installed at the bottom of the main housing 1, a limit ball 3 rotatably connected to the inner wall of the guide shell 2, and a feeder shell 4 provided on one side of the main housing 1.

[0024] The limiting ball 3 is provided with a through hole 31. The upper opening of the through hole 31 is connected to the internal space of the main box 1, and the lower opening of the through hole 31 is connected to the internal space of the guide bottom shell 2. The inner wall of the through hole 31 is provided with a filter net 32 ​​for filtering sand.

[0025] It should be noted that the limiting ball 3 described in this embodiment controls the discharge of sand inside the main box 1 through the through hole 31 and its own rotation.

[0026] The main housing 1 is connected to the internal space of the guide bottom shell 2, and the guide bottom shell 2 is connected to the internal space of the feeder housing 4.

[0027] It should be noted that the sand inside the main box 1 described in this embodiment can pass through the through hole 31 and the guide bottom shell 2 and be fed into the feeder shell 4.

[0028] A feeding port 41 is provided on one side of the feeder housing 4, and the feeding port 41 corresponds to the position of the main housing 1. A rotating rod 42 is rotatably connected to the inner wall of the feeder housing 4, and a feeding propeller 43 for guiding sand is installed on the side wall of the rotating rod 42.

[0029] It should be noted that, in this embodiment, the feeder housing 4 conveys sand from the bottom to the top inlet 41 position through the rotation of the rotating rod 42 and the feeding propeller 43.

[0030] The top of the feeder housing 4 is equipped with a drive mechanism 421 that drives the rotating rod 42. The bottom of the rotating rod 42 is electrically connected to a slip ring 44, which is installed at the bottom of the feeder housing 4.

[0031] It should be noted that the rotating rod 42 described in this embodiment is a drive motor, and both the rotating rod 42 and the feeding propeller 43 are equipped with heating wires. The collector ring 44 is powered by an external circuit.

[0032] Specifically, to address the issues of sand getting damp and contaminated with garbage, the main housing 1 feeds sand into the through-hole 31 through an opening at the bottom. The filter bag 32 within the through-hole 31 intercepts and filters the passing sand, trapping impurities and debris. The filter bag 32 is a soft filter structure, allowing it to be pulled towards the main housing 1, causing it to flip outwards for easy cleaning of internal debris. This design is simple and convenient. When the limiting ball 3 rotates, it blocks the opening at the bottom of the main housing 1, ensuring a stable internal structure for patient use and preventing accidental sand leakage. The guide shell 2 supports the limiting ball 3. After passing through the through-hole 31 and the filter bag 32, the sand enters the internal space of the guide shell 2, which then guides the sand into the feeder. Inside the shell 4, the connection between the bottom guide shell 2 and the feeder shell 4 is located at the bottom of the feeder shell 4, allowing the sand to be driven and conveyed by the feeder propeller 43. The power line provides power to the heating wire inside the rotating rod 42 and the feeder propeller 43 through the slip ring 44, so that the rotating rod 42 and the feeder propeller 43 heat the sand as they guide it upward, causing the moisture in the sand to evaporate and improving the sand's performance. When the sand is conveyed to the top of the feeder shell 4, it is fed into the main box 1 from the inlet 41, completing a cycle of use. No additional processing of the sand is required; only the waste in the filter bag 32 needs to be removed. The process is time-saving and labor-saving, fundamentally solving the problem of cumbersome sand handling and meeting the needs of efficient and convenient psychological sandplay in actual use.

[0033] In one embodiment of this utility model, such as Figures 1-5 As shown, a connecting ring 321 is installed at the top of the filter bag 32, and the connecting ring 321 is installed on the inner wall of the through hole 31. A counterweight rod 322 is installed at the bottom of the filter bag 32. Neither the connecting ring 321 nor the counterweight rod 322 is in contact with the main box 1. A weight-reducing hollow inner groove 33 is opened in the limiting ball 3.

[0034] Specifically, the connecting ring 321 supports the filter bag 32, and the filter bag 32 reduces its diameter with the connecting ring 321 as the supporting surface, so that there is a gap between the filter bag 32 and the through hole 31, which facilitates the filtration work. The counterweight rod 322 pulls the filter bag 32 down, so that the filter bag 32 can be in a relatively stable state during filtration. Furthermore, when the filter bag 32 is pulled up and flipped outward, it can be operated by pinching the counterweight rod 322.

[0035] In one embodiment of this utility model, such as Figures 1-5As shown, an L-shaped drive rod 34 is installed on one side of the limiting ball 3. One end of the L-shaped drive rod 34 is rotatably connected to the inner wall of the guide bottom shell 2, and the other end of the L-shaped drive rod 34 is rotatably connected to the outer side of the guide bottom shell 2. A handle 341 is rotatably connected to one side of the L-shaped drive rod 34.

[0036] Specifically, the design of the L-shaped drive rod 34 and the handle 341 makes it convenient for staff to manually operate the rotation of the limit ball 3. By holding the handle 341, the rotation angle of the limit ball 3 can be easily controlled, thereby controlling the sand filtration volume and discharge speed, as well as the sealing and opening control adjustment of the opening below the main box 1.

[0037] In one embodiment of this utility model, such as Figures 1-5 As shown, two limiting magnetic rods 21 are installed on one side of the guide bottom shell 2, and metal plates 342 are embedded on both sides of the L-shaped drive rod 34. The metal plates 342 are magnetically attracted to the corresponding limiting magnetic rods 21.

[0038] It should be noted that the L-shaped drive rod 34 described in this embodiment can only rotate between the two limiting magnetic rods 21.

[0039] Specifically, the limiting magnetic rod 21 and the metal plate 342 are magnetically attracted to each other, which can fix the limiting ball 3 when it rotates to a specific position, preventing the limiting ball 3 from rotating randomly and ensuring the stability of the sand filtration and discharge process. After the sand filtration is completed, the metal plate 342 and the limiting magnetic rod 21 are magnetically attracted to each other, keeping the limiting ball 3 in a suitable position. At this time, the feeder housing 4 can stably guide the filtered sand without affecting the sand transmission due to the shaking of the limiting ball 3, ensuring the stable operation of the device.

[0040] In one embodiment of this utility model, such as Figures 1-5 As shown, a support base 5 is installed at the bottom of the feeder housing 4, and the guide bottom shell 2 and the main box 1 are both located directly above the support base 5.

[0041] Specifically, the support base 5 provides support, ensuring the stability of the entire device, preventing it from tipping over due to an unstable center of gravity during use, protecting the internal structure of the device and the sand, and improving safety during use.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] Working Principle: When the sand in the psychological sand tray needs to be processed, the sand in the main chamber 1 enters the through-hole 31 through the bottom opening. The filter bag 32 on the inner wall of the through-hole 31 intercepts and filters the passing sand, leaving the mixed debris inside the filter bag 32. Since the filter bag 32 is a soft filter structure, it can be turned outward by pinching the counterweight rod 322 and pulling it upward, making it easy to clean the debris inside. The connecting ring 321 provides support for the filter bag 32, creating a gap between the filter bag 32 and the through-hole 31 to facilitate filtration. The counterweight rod 322 pulls the filter bag 32 downward, ensuring the stability of the filter bag 32 during filtration, thus completing the filtration process. The sand passes through the through hole 31 and the filter screen 32 into the bottom guide shell 2. The bottom guide shell 2 guides the sand into the inside of the feeder housing 4. The drive mechanism 421 at the top of the feeder housing 4 drives the rotating rod 42 to rotate. The rotating rod 42 drives the feeding propeller 43 on the side wall to rotate synchronously, thereby conveying the sand located at the bottom of the feeder housing 4 upward. The power line supplies power to the heating wire inside the rotating rod 42 and the feeding propeller 43 through the collector ring 44, heating the sand during the sand conveying process, evaporating the moisture in the damp sand, and improving the sand's performance. Finally, the sand is conveyed to the feeding port 41 at the top of the feeder housing 4 and is then fed back into the main box 1 from there, completing one usage cycle.
